The recent discovery that a gravitational wave GW170817, that resulted from a binary neutron star merger   arrived at the same time (to within ~1.7 s) as the gamma ray burst GRB170817A   , and that electromagnetic (EM) radiation over a wide spectrum was detected within a short time period, as summarized in  , demonstrated that gravitational waves (GWs) travel at the same speed as EMWs through intergalactic space (IGS) and the Milky Way (MW) with negligible dispersion. However, the purpose of this work is to point out that it does not necessarily follow that the GWs and EMWs traveled through the IGS with the vacuum speed of light, because of a new description of dark energy proposed by the author recently     , in which an alternative to the accelerating universe was introduced to provide another explanation for the increased apparent magnitude of the Type Ia supernovae (SNe Ia) that led to the accelerating universe    . The model assumes that dark energy is only in IGS, and that it does not have a negative pressure causing the universe to accelerate, but for , later reduced to , it has an index of refraction n, with that results in the speed of light through IGS to be reduced to ~2c/3. However, the speed of EMWs as well as GWs within the galaxies themselves is c. Although the particle nature of dark energy is left open, it is proposed that dark energy is a different phase of dark matter. The Einstein de Sitter (EdS) universe, with a multiplicative correction for distance, was used as the alternative to the ΛCDM universe, with which it was compared, in order to determine n by a least squares fit which yielded . In the previous work     , there was no discussion of GWs, but now, because of the above finding that GWs travel at the same speed as EMWs, it follows that the model predicts that GWs also travel through IGS with reduced speed c/n. As a further prediction, it is shown that the reduced speed of light leads to a redetermination of the Hubble constant, which in turn leads to a resolution of a long-standing difficulty concerning the age of the EdS universe. Since no dispersion was observed over the optical range in the SNe Ia studies    , it was noted in  that if this held over the entire EM spectrum, as has now been shown to be the case, this would provide a simple explanation for the absence of neutrino correlation with GRBs found by IceCube   , which is further extended in this work to include the negative findings of Borexino   . Additional references to other negative findings are also given below. It is proposed that the predicted speed reduction through IGS for GWs that is the same as that for EMWs, together with a possible relation of electromagnetic parameters to gravitational parameters noted previously    , as well as the absence of dispersion, are implications of a unified theory of gravitation and electromagnetism. There is a brief description, based on earlier work  , on how the model can be tested astronomically by searching for heretofore ignored possible galactic sources of discordant redshifts, together with an improved discussion over that given previously of how this type of search could be used to falsify the model.
2. Determination of Index of Refraction
A least squares fit of n, denoted by n(ls), to the increased apparent magnitude of the SNe Ia given in  for the ΛCDM universe, based on a comparison with the EdS universe, and a correction to the apparent magnitude δm, led to for . The correction δm was shown in  to be given by
in which n was taken to be a constant independent of z. Fiducial values of the cosmological density parameters, , were used in  . In  , Table 1 gives the percentage agreement for the increase in apparent magnitude of the SNe Ia for the EdS universe with that for the ΛCDM universe, when the correction δm is taken into account. The model can also account for the increased distances to the “standard ruler” of the baryon acoustic oscillations (BAO)   , with the logarithm of the fractional correction to the distance given by
Also in  , Table 3 makes the comparison for d. As expected, the two Tables are in perfect agreement when rounding-off errors are allowed for, since . The percentage of agreement of the model with ΛCDM ranges from −6.7% for z = 0.1, to 6.7% for z = 1.0, with zero disagreement for . For the BAO, there are two distances: The angular distance and the luminosity distance that differ by factors of . However, for the ratio , and that for , the factors cancel, so that they have the same logarithm given by d. This increase of distance, and hence size of the EdS universe, because of the reduced speed of light, can be shown to give an alternative explanation to the Large Scale Structure (LSS) studies that support the accelerating universe, but for brevity will not be given here.
3. Dark Matter and Dark Energy
It was also assumed that dark energy, characterized by its macroscopically-large index of refraction, results from the dark matter that was originally in IGS having undergone a phase transition due to its cooling because of the expansion of space. In contrast, the dark matter associated with the galaxies themselves did not develop such an index of refraction, since galaxies do not expand with the expansion of space, so that the speed of light within the galaxies remains the vacuum speed. Thus, in this model, dark energy is a different phase of dark matter, not a different substance, the particle nature of which is left open. For simplicity, it is left to later work to take into account that there will be a transition region at the outermost halo regions of galaxies, so that n will not jump sharply from within a galaxy to in the IGS. Also, since at the universe appears to have started to accelerate  , it is assumed that the phase change into dark energy began at about this value of redshift, in which the index of refraction started to rise from to . Since the EdS universe continued to decelerate during this phase change there is no difficulty with the Copernican principle, as far as the expansion of space is concerned, unlike the case for the accelerating universe. However, at this point, there is a problem: The EdS universe works with cold dark matter, hence it is at zero temperature, yet the model assumes it was the cooling of dark matter in the IGS that led to the phase transition. The neglect of this problem is another simplification a more advanced model will have to address, possibly by working with some form of warm dark matter, for which there is wide discussion in the literature. Thus, in this highly simplified model, the dark energy contributes only to the energy density of the source tensor, so that with the dark matter plus baryon matter, for the flat EdS universe, one has . Although the flat EdS universe was used for comparison with the flat ΛCDM universe, the corrections provided by (1) or (2) do not require this. Thus in  , the EdS value for n(ls) was obtained for comparison with a closed universe with , a somewhat greater departure from unity than for Planck  , with curvature density . There is also a critique of the cosmological term in conjunction with this study in  , as well as another in  .
4. Electromagnetism and Density Parameters
In an attempt to understand how the value of n might be related to cosmological density parameters, it was noted in  that if one assumes the dark energy behaves as an isotropic linear medium in electromagnetic theory, then , where K is the dielectric constant, and is the relative permeability, and that if one further assumes
where is the density parameter for dark energy, and is the same in magnitude as the density parameter associated with the cosmological term, so that , then
For the fiducial values of and used to determine n from Equation (1), one obtains , in good agreement with . Since for , where , because the proposed phase change has not yet occurred, based on the finding in  , Equation (4) only holds near the present epoch, where n can be taken as constant. It was later found that if instead of basing on the range of redshifts , one chose , then . This smaller range was chosen partly on the basis that the increasing disagreement with the ΛCDM at the higher redshifts is due to the possibility that the proposed phase transition is not complete, so that n < 1.5 for these higher values of z, and also partly because kinematic considerations, given below, suggest . This reduced range of redshifts includes the range for the BAO studies   whose distance measurements were for galaxies with an effective redshift . One can now use to re-determine and by employing Equation (4), and the prediction that from the EdS model, which is also the prediction of inflation    , although independent of it. From these two relations one obtains
and with , one has , which is in perfect agreement with the Planck  value, , which in turn is in excellent agreement with the BOSS  value, , based on BAO studies of the flat ΛCDM universe. One can now redo the least squares determination of n, using the new values, , and , for the accelerating universe, and for , and one finds again . This value for n, together with further analysis, will make it possible next to resolve the problem concerning the age of the EdS universe. Note; Planck  gives slightly different values for and the Hubble constant; however, in view of the magnitude of the uncertainties, such changes will be ignored.
Finally, to correct the discussion of the behavior of in  , it was later noticed one should have for instead of . This can be achieved if instead of (3) one sets
so that , where , and for , and for . Also, for , and for . Then one has
and hence for , , and , as required. It is possible the contemplated unified theory will help to justify (6).
5. Age of the Universe, and the Hubble Constant
As is well-known, the age problem arises as follows: The expansion parameter in the Friedmann, Le Maître Robertson Walker (FLRW) line element, , ( ), for the flat EdS universe, obeys the equation , where is the time from the Big Bang to the present epoch, for which , and hence it is the age of the EdS universe. The Hubble constant , from its definition as , is therefore given by , so that the age satisfies . For the approximate value, (current values of are given below), one has , which is in significant disagreement with the ages of the oldest globular clusters in the MW, with a best fit of 12.6 Gyr  . The resolution is to notice that one of the assumptions that is made in determining the Hubble constant empirically is that the light from the red-shifted galaxies traveled through the dark energy of IGS with speed c. However, apart from the time light spent traveling through the MW with speed c (which can be neglected for this preliminary work since it is estimated to contribute less than ~0.5%), according to the model, the light actually traveled through IGS with speed c/n. Also, since the redshifts used in determining satisfy , as noted below, it is justifiable to treat n as a constant. Then, from the first-order Doppler-effect, that can be used to determine , when higher-order corrections are neglected, one has , instead of , where v is the speed of the receding galaxy after possible peculiar velocity has been taken into account.. Hence, with , one has , instead of the customary . Since the relation that originally defined the Hubble constant can be written , where D is the proper distance to the receding galaxy, upon introducing the expression , to allow for the reduced speed of light, one has
It follows that the age of the EdS universe, instead of that given above, is actually given by
For there is obviously an exact cancellation of the 2/3 factor (to be further discussed below), so that the revised age of the EdS universe is , which is the same as for a universe that had expanded uniformly. For , from Planck  , and from (9), for , the revised age of the EdS universe is
It will be noted that this age is significantly greater than the age of the ΛCDM universe given by Planck  as . This is because the decelerating EdS universe necessarily takes longer to expand to than the accelerating universe. It was noted in  that the ages of the oldest stars in the MW could help to determine which age is more likely. For example, the subgiant HD140283 was found to have an age of  that is accommodated more readily by the EdS age than that of the accelerating universe. Nevertheless, as pointed out in  , because of the large uncertainty in the star’s age, it could still be younger than the age of the universe, given then as . A related issue concerns the present tension between the Planck  value of , based on the CMB, and the value  , that emerges from a local determination, based on the cosmic distance ladder (CDL) that uses the Cepheid variables, and the SNe Ia for . This tension shows up for the model in the following way: Thus, the CDL determination of leads to a Hubble time, , and hence with in (9), yields an age for the EdS universe of , which is in tension with the age of HD140283. In contrast, the Planck  value of is consistent with a BAO determination that yielded  , and the value from BOSS that yielded,  . However, HOLiCOW  , based on gravitational lensing, employed a fiducial value , which favors the CDL value, hence HOLiCOW is also in tension with the CMB and BAO determinations, as discussed in the literature, and hence with the model as well. Also, as noted in  , the GW signal, together with redshift measurement, yield  ; however, because of the large uncertainty, it is compatible with both groups.
It was noted above that for , there is an exact cancellation of the 2/3 factor in (9), which would seem to imply that n is the reciprocal of the 2/3 factor. Although a dynamical explanation has not been found, there is the following kinematic explanation. Since the Hubble constant for a universe that expands uniformly, denoted here by , satisfies , and since for the EdS universe, one has . Hence, in (8), if one sets , and , one obtains . However, this does not explain dynamically how the dark energy could acquire this value of n, along with the absence of dispersion. As suggested above, possibly such an explanation, including one for (6) would emerge from the contemplated unified theory, as well as a prediction of the functions and .
6. Absence of Neutrinos Correlated with GRBs
Another type of prediction concerns failed attempts to correlate high energy neutrinos with gamma ray bursts (GRBs) as discussed in  , which will be further extended here by considering a lower range of neutrino energies that was not discussed earlier. But before doing this, it is appropriate to comment on the neutrinos from SN 1987a    in the Large Magellanic Cloud. It was found that the light arrived 2 - 3 hrs after the neutrino detection, see ref.1 in  . However, if dark energy were present between the LMC and the MW, that extended for a distance as small as, say, one light-day, a reduced speed for that distance with would have led to a time difference of ~12 hrs, plus the time for the light to leave the supernova. Although a smaller distance cannot be ruled out, it is more likely the dark matter halo of the MW overlaps with the LMC in such a way that the cosmological expansion of space between the two galaxies either did not occur, or if it did, it was negligibly small. Thus, in this sense, the LMC is not extragalactic to the MW.
For brevity, only IceCube   and Borexino   findings will be discussed next, but other searches for a wide range of energies with the same null results are in  -  . As noted in  , IceCube  found no correlation of high energy neutrinos with GRBs, while in  two PeV neutrinos were observed that were not correlated with any GRB. One possible explanation is that the sources of GRBs, although enormously energetic, do not produce a fluence of high energy neutrinos sufficient enough to be detected, and that the PeV neutrinos just happened to be passing through IceCube, is discussed in  . The proposed model suggests another possibility: Since according to it, GRBs travel with speed ~2c/3 through IGS, even if GRB sources did produce a sufficient fluence of neutrinos, they would have arrived millions of years before IceCube was built. While the two PeV neutrinos were possibly associated with an event that produced a GRB that will not arrive until the distant future. Indeed, according to the model, under the well-established prior that GRBs, along with accompanying optical and radio waves    , arise from cosmologically-distant sources, neutrinos from such sources, even if the fluence were sufficient to exceed background, could never show any correlation with a GRB. This prediction is supported by Borexino’s failure to find any low-energy (1.8 MeV - 17 MeV) neutrino and anti-neutrino signals correlated with GRBs  . In particular, Borexino’s search from 2007 to 2015 for neutrino and anti-neutrino events correlated with 2350 GRBs, found no statistically significant excess over background. A possible explanation that assumes that there was too small a fluence of neutrinos and anti-neutrinos from GRB sources requires 2350 assumptions, one for each event, with no way to check empirically. More recently, Borexino searched for neutrinos correlated with the arrival of GWs  , but none were found, beyond solar and background neutrinos. Thus, it is sufficient for the above proposition to be valid, if the speed of the GRBs and the GWs through IGS is ~2c/3 for . Indeed, from the standpoint of Occam’s Razor, it is the preferable explanation, since it is much simpler. Two astronomical tests of this assumption for visible light are of special interest, because they can be readily carried out, and for completeness will be summarized next, with some abbreviations to the discussion in  , as well as some improvements.
7. Discordant Redshifts
Astronomers have observed galaxies to have seemingly close companions with higher redshifts that have led to their description as “discordant redshifts”. The current explanation, in accordance with the generally accepted view that higher redshifts correspond to greater distances, is that the higher redshift companion is the image of a galaxy that is behind the lower redshift galaxy, and shining through, thereby giving the impression that it is near the lower redshift galaxy, even though it is at an astronomically-large distance behind it. The term, “accidental superposition,” is used to describe this scenario. An analysis of 64 cases of discordant redshifts, compiled by Arp  , who disputed the standard explanation, led Bahcall  , after making suitable assumptions, to estimate that ~40 cases were due to accidental superposition. He went on to conclude that, in view of the large uncertainty in the numbers he was using, all the cases were due to accidental superposition. However, the author’s re-examination in  of Bahcall’s estimate  , found that he had rounded-up two of his proposed numbers before taking the product that led to the estimated ~40 cases, and that when one did not round-up, the ~40 cases were reduced to 30 cases. This suggested that about half of the 64 cases are due to some other cause, which the model provides, as will be shown next.
Assume that off to the side, angle-wise, of the lower redshift galaxy there is a higher redshift galaxy that can be viewed directly by the astronomer, although, because of the well-known general relativistic deflection of light that passes outside, but near, the lower redshift galaxy, the higher redshift galaxy will appear shifted by a small angle from its actual position. Also, a light ray from the higher redshift galaxy, that travels at a suitable angle with respect to the direct ray, and strikes the lower redshift galaxy at an angle , less than the critical angle relative to the local normal, upon entering the galaxy, because of Snell’s law, will be bent away from the normal by an angle , with , in accordance with for IGS, and for the galaxy, Since galaxies do not have sharp boundaries, the actual refraction will take place gradually, and depend on the variation of the index of refraction from its value in IGS, to that within the galaxy. However, if the variation is sufficiently smooth, this should not affect the qualitative result. After entry, the light will then travel straight through the lower redshift galaxy, in the absence of scattering and/or absorption, and, upon exiting, it will be bent towards the normal, and then, under suitable geometrical conditions, travel on to the astronomer, who will see an image of the higher redshift galaxy as a companion to the lower redshift galaxy, and describe it as a discordant redshift. An idealized figure is in  in which the lower redshift galaxy is treated as a perfect sphere with a sharp boundary, and refraction of the light entering the MW is ignored.
Thus, to test the model, astronomers might look for higher redshift galaxies that are off to the side, angle-wise, of lower redshift galaxies that match the higher redshift of the companions and their other features. If such galaxies were found, it would validate the model, but if they were not found, it would not necessarily falsify it, since such a finding would indicate that Bahcall’s conclusion was correct, but not some of his estimated numbers. However, the model would certainly be falsified if a higher redshift galaxy were found off to the side, angle-wise, of a lower redshift galaxy, and in such a position that it could have given rise to a discordant redshift companion, but did not, since this would mean that light had entered the lower redshift galaxy without experiencing refraction, in conflict with the model.
If the model were to pass the proposed astronomical tests, not only would it provide an alternative explanation to the accelerating universe for the increased apparent magnitudes of the SNe Ia, and the increased distances to the standard ruler of the BAO, but in view of the recent discovery     that the speed of a GW is the same as that of a GRB, it would indicate that GWs also experience the same reduction in their speed through the dark energy of IGS as EMWs, a possibility that was not considered in     . This possibility, along with the proposed relation of EM parameters to gravitational parameters in (3) and (6), together with the absence of dispersion, may be seen as implications of Einstein’s long-sought unified theory of gravitation and electromagnetism. Other predictions of the model are: dark energy as a different phase of dark matter, an increased age of the universe, a reduced value for the Hubble constant, and, significantly, the absence of the arrival of neutrinos correlated with either GRBs or GWs, a prediction that, in the case of GRBs, is already supported by numerous observations.

LED represents light emitting diode and it's also the most efficient lighting technology that's developing most rapidly these days. When you've got the highest quality LED, you will benefit from the greatest durability and light when compared with other kinds of lighting. There are many things you might not know about this type of lighting, though if you did, you'll agree that it is the best kind of lighting as compared with others.
This kind of lights are power efficient to a very large degree plus it comes with the potential of adjusting the complete lighting structure on the planet. There are several sorts of LEDs plus some bring residential purposes. Among those which might be the best save around 75% of their time and they also last around 25 times when compared to the incandescent lighting. This will mean great savings, in particular when a lot more people decide to use this kind of lighting down the road.
Differences along with other varieties of lighting
There's a massive difference involving the LED types of lighting in comparison with others.
The sunlight source: this is one of the differences. LEDs are of a fleck of paper size. They're also a mix of blue, green and red and so they emit white light.
The direction: LEDs usually emit their light really specific direction and therefore you don't have to work with diffusers and reflectors to capture light. This makes them very efficient for numerous uses. Other sorts of lighting require reflection and often much of the light isn't getting to areas targeted.
Heat: usually, there's little or no heat emission. The incandescent bulbs release around Ninety percent of one's by means of heat whilst the CFLs stand at 80 percent.
Different purposes of LED
Today, there's a wide selection of industrial and home products that offer LED lighting. Their email list continues growing. This rapid expansion of we've got the technology has generated more products along with efficiency in manufacturing and that's why consumers can also enjoy even more affordable prices. One of the most popular products include:
Commercial and industrial lighting: since LEDs are directional and efficient in nature, it's caused them to be a good idea for plenty of industrial uses. These are quite commonly used in parking garage, streets, walkways and some other type of outdoor areas that need light. Others include task lighting, modular lighting, in addition to refrigerated case lighting.
Lighting with the cooking: LEDs are directional and small , hence they are fantastic for countertop lighting useful for reading recipes and cooking. The color appears blue or cooler than most would desire in a kitchen and shadowing can occur. It is therefore important to select the products carefully so as to discover what is most ideal within your target space.
The recessed downlights: these are generally often employed in bathrooms, hallways and residential kitchens along with different commercial and office settings. Most people are while using the downlights as well as the LED has decreased wattage to some degree.
High bay led lights are the best option if you're looking to get a great lighting option. There are plenty of bay LED lamps that you could pick from. Using LED lighting could have a direct impact in your home along with your pocket, so that it is one of the most reasonable option for all.

Experts say water damage from wind-blown attic snow could worsen with melting
Just as the lingering snow and ice from the weekend's Winter Storm Goliath seem to be diminishing on Lubbock streets, they're posing new threats in Lubbock area homes.
The city of Lubbock released a statement Wednesday warning homeowners of possible snow accumulation in attics after the city saw more than 11 inches of snow in what is not the third greatest snowfall event in the city's history.
"Homeowners are encouraged to check their attics for possible snow accumulation. High winds may have blown snow into homes through the attic vents, especially those on the north side of homes. Melting snow could cause sheetrock problems," according to the release.
Few know about it better than Lubbock area water damage repairmen like Joel Mowery and Warren Johnson.
And it's a problem they expect will get worse as the snow and ice melt and homeowners and business owners start noticing water dripping or water-soaked rings forming on their ceilings.
Mowery, co-owner of Servpro in Lubbock, said it's a problem he's having to deal with at work and at home.
As he and his crews were responding to about half a dozen snow-in-attic or roof collapse calls - including at a section of the South Plains Mall - Mowery got a call from his daughter reporting water was dripping from their ceiling.
"Well, I'm out here helping everyone else's attic," he said with a chuckle.
Both Mowery and Warren described a relatively straightforward process to remedy the immediate problem. The water-saturated insulation must be removed to allow the area to dry to prevent mold or mildew buildup. Depending on the magnitude of the problem, crews may have to replace damaged sheet rock.
Removing the insulation is necessary to help the attic dry but also poses other risks, including exposing pipes to freezing air that could cause them to burst.
"It's a difficult situation," he said.
Warren, a co-owner of Rainbow International in Lubbock, said it's a problem that can be difficult to prevent, but said actions such as covering vents such as turbine ventilators can help.
Along with the South Plains Mall roof collapse, Mowery said his company has responded to a couple other ceiling collapses due to melting snow. One way to prevent a sagging ceiling from caving in is to poke a whole in it with a screw driver, alleviating the pressure. It's good to have a bucket to collect the water.

Now your Smok can smartly adjust the voltage to provide you with a longer, more flavorful Vapor. Another great feature is a built in “drip around” electrode so any moisture produced while vaporizing can easily wick away.
While the strength output and overall performance of both the Smok Novo 2 Package is great, the true advancement comes coming from how a devices talk with one other. The note 2 system comes with 2 metal plates on the base that a lock the screen in place. The screen is completely enclosed, keeping warmth and other outdoors influences from influencing the device. This guarantees your unit will constantly be working at its optimal level, no matter what else you usually are doing.
One of the particular first things I noticed about the Smok Novo a couple of was how effortless it was to employ. With the incorporated manual, the user has everything they will need to get going including the two starter kits. Also though there is a digital keypad situated on the side, I didn’t have any issues with getting the controls. When you are finished charging the unit, it makes environment up simple as just installing typically the two noVo a couple of pod system fittings on the bottom part side from the package.
Together with the electronic temp controller (ECC), typically the e-liquid level in the reservoir is automatically adjusted based about your present vaporizer options. This allows you in order to slowly mix your current liquid so it doesn’t dry out too quickly before it is usually ready to be ingested. Another positive aspect of the Smok Novo 2 will be the two various sized tanks which usually provide an improve in vapor top quality. The larger tank will be meant to be used regarding a longer duration of time while the particular smaller tank will be meant used in between sessions.
My simply gripe with the particular Smok Novo two Pro is the non-automated power result reduction feature. Although it caused it to be easier to control our vaporizer since the particular power output was limited, it took a new few minutes in order to figure out how you can properly implement the particular feature. When changing between different power settings, the gadget would often totally reset itself resulting within a loss associated with vapor quality. Thankfully, this may not be a frequent occurrence and most users have had simply no issues with this specific power reduction feature. In general, the Smok Novo 2 creates a much longer-lasting lasting vapor as compared to the original.
The Smok Novo 2 Pod System is a great excellent upgrade for any avid vaper who prefers an even more automated experience whenever you need to change their vapor options.

The Sultan of Sokoto, Alhaji Saad Abubakar III, on Friday charged political leaders in the country to intensify efforts in satisfying the needs of the people.
Abubakar gave the charge in Katsina at the inauguration of Shehu Usman Dan Fodiyo Friday mosque constructed by the state government.
He said that politicians were elected to serve the people and the nation, hence the need for them to give priority to the welfare of the electorate.
Abubakar said that they should try to emulate past leaders who were being remembered for the selfless services they rendered to people.
He urged the followers to continue to pray for the well-being of the leaders and for peace and unity in the country.
The sultan noted that development could only be achieved in peaceful environment, urging Muslims faithful to reflect on the teachings of Islam and respect the faith of other believers

This paper describes the novel development of a micro-tensile testing method that allows testing at elevated temperatures. Instead of using a furnace, a titanium/platinum thin film micro-heater was fabricated on a conventional dog-bone-shaped test structure to heat up its gauge section locally. An infrared (IR) camera with 5 µm resolution was employed to verify the temperature uniformity across the gauge section of the test structure. With this micro-heater-integrated test structure, micro-tensile tests can be performed at elevated temperatures using any conventional tensile testing system without any major modification to the system. In this study, the tensile test of the single crystal silicon (SCS) thin film with (1 0 0) surface orientation and 〈1 1 0〉 tensile direction was performed at room temperature and elevated temperatures, up to 300 °C. Experimental results for Young's modulus as a function of temperature are presented. A micro-sized SCS film showed a low dependence of mechanical properties on temperature up to 300 °C.

Ambitious plans to revamp the shopping heart of Newcastle city centre could bring millions more visitors to the city, add £78m to the local economy and create up to 300 new jobs.
Newcastle City Council has unveiled an initial £3m plan to transformation the area around Northumberland Street and maintain its place as one of the country’s prime retail destinations.
The scheme would see an experimental closure of Blackett Street to traffic, the creation of new event space on and around Northumberland Street and a huge cleaning operation in the city centre.
But the authority has larger plans for a £20m scheme which could fully pedestrianize Blackett Street and would see the focus move onto the empty plot of land on Pilgrim Street that is hoped would attract high-end shops, as well as housing and offices, to the city centre.
A council study of the long-term plans estimates that they could lead to an additional 2.6m people coming to the city centre, 300 new jobs, and almost £78m gross value added to the local economy.
But the council is unlikely to have all of the funding for that scheme and will need to get support from private companies and other public organisations to make that happen.
The plans have been drawn up by the council in partnershp with businesses in the city centre which have formed a Northumberland Street Working Group.
Mark Williams, independent chair of that group, said: “These plans form the first stage of an ambitious programme that a wide group of stakeholders have contributed to and support, as it impacts their city and investment.
“The council are leading by funding this phase, following which they and all other stakeholders need to contribute to the expansion and running of these improvements. The approach though is ground breaking and one which others will look to follow.”
Sean Bullick, chief executive of Business Improvement District NE1, added: “We now need to connect all those areas up by curating the city centre to increase footfall and dwell and to improve the relationship between the retail and the leisure offer. This initial investment and the interventions planned really up our game, and support our ambitions to become an international destination of choice.”
The initial £3m package set to be agreed by the council next week will create new spaces for activities, entertainment and events - partly on Northumberland street and partly by extending paving on Northumberland Road to create an extended pedestrian space.
It is also proposed to reorganise and enhance street trading and alter servicing arrangements to properties, offering a less cluttered and people friendly environment.
Blackett Street will be changed to remove buses on a trial basis to give people priority, with buses using the existing loop around John Dobson Street, New Bridge Street, Pilgrim Street, Market Street and Percy Street.
It is hoped to have the street blocked to traffic in time for next year’s Great Exhibition of the North.

New rumors suggest that Apple entered two new connectors in the next iPad Pro. Their purpose is not yet clear, but it seems they can be used to power peripherals. The only certainty is that they are totally unpublished.
iPad Pro, the next generation will have two new connectors
According to “reliable sources in China” cited by Mac Otakara, the next ones iPad Pro 11 and 12.9 inches they will have the same design, the same body. But two new connectors, both top and bottom on the device (oriented horizontally).
These two new inputs will have four pins. So one more than the Smart Connector, used by Apple to connect accessories such as the Magic Keyboard to its most powerful tablet. And one less than the connector MagSafe 3which allows you to recharge the i MacBook. So a totally new hardware interface for the Apple.
According to Mac Otakara, these could be inputs designed to load peripherals connected via port Thunderbolttaking advantage of the new DriverKit in iPadOS. But this remains only a hypothesis: at the moment it is difficult to understand their use.
Especially since Apple seems to have decided to place two in the body of the iPad Pro. It could be just a choice of convenience. But given the difficulty of having to then test iPads for safety and resistance to water and dustit seems difficult to think that they are not two for a good reason.
Apple had introduced it Smart Connector in 2015 on the iPad Pro, to then introduce theUSB-C n2018 and a door Thunderbolt in 2021 (thanks also to M1). This seems like a new evolution, but in what direction?
Apple should unveil the devices in the coming months, but it seems not at the event of the September 7, when it introduces iPhone. We should therefore wait a little longer to discover the usefulness of these new ports.

I heard about this latest bit of pro-abortion news yesterday afternoon. Normally, I would have been seized by the urge to blog. But I have been flying solo this week, taking the full brunt of running the household while my husband is out of town. Not to mention finishing my [expletive deleted] LL.M. thesis and looking for gainful employment. I am tired. And suddenly, I was overcome by a feeling that the battle had been lost, that everything had been written, every argument laid out, and still, people didn’t care.
But when I heard that the said award had been granted for “outstanding service to humanity and for his contribution to the cause of equality for women” the feeling of hopelessness was quickly replaced by an overwhelming urge to yell at someone. I tried writing, I did. But I couldn’t write anything that wasn’t seasoned with a generous dose of profanities. Out of respect for our beloved readers, I chose to run 5 km during my daughters’ gym class before heading home at 9 pm to make lunches, clean the kitchen, run a load of laundry, sign permissions, take out the trash, read bedtime stories, and watch three consecutive episodes of Jon & Kate +8 while checking my emails. In the end, I went to bed way too late to be angry and am therefore in a much better disposition to write a well-balanced thoughtful post. Well, we’ll see.
Equality for women. The cause of equality for women. And what would be abortion’s contribution to equality for women? We hear it so much we no longer pause to wonder “oh yeah? and why is that?” This is not a rhetorical question. We need to reflect on the underlying assumptions of making abortion an “equality” issue. Because if equality between men and women really hinges on access to abortion, we are a lot farther behind achieving meaningful equality than we flatter ourselves to be. Women need abortion to be equal in order not to be weighted down by children.
This premise contains, at first glance, two important inequalities. The first one being that men are not (or shouldn’t be) weighted down by children. The second one being that children are social dead weight. I believe that thoughtful abortion advocates would see clearly through the inequality of equality through abortion but would counter-argue that in the present circumstances, it is unfair to make women bear the brunt of our social inertia. But what pro-woman pro-life advocates see is that equality has been achieved at the cost of fairness and that access to abortion has only promoted the inferiority of women as bearers of children. The vicious circle has to stop an we need to make women equal as they are — with a uterus and all — not as society wishes them to be.
Equally problematic is the notion that equality in society is somehow “granted.” Think about it: we have “achieved” equality with access to abortion. Shouldn’t we just “be” equal? Doesn’t the very idea of having to achieve equality fundamentally unequal and unfair? It would be equivalent to saying that immigrants achieve equality once they become white, anglo-saxon and Protestant. What kind of equality is that?
Let’s not wonder why there’s misunderstanding over the fabric of the abortion issue in this country.
To correct the above phrasing, the court’s ruling in 1988 declared the law that regulated access to abortion to be unconstitutional. Over 20 years later, and no new law regulating access to abortion has been passed, contrary to the wishes of the Supreme Court. “thus confirming” nothing…nothing at all. On se permet des choses, en tout cas!

Judge Lucy Koh called Qualcomm's licensing practices on cellular patents anti-competitive in a sweeping 233-page decision
Qualcomm must end its “no license, no chips” policy and renegotiate all of its existing licenses for cellular patents, a San Jose judge ruled. The 233-page decision will impact virtually all cellular chip and systems vendors on the cusp of a transition to 5G.
Judge Lucy Koh also ruled that Qualcomm cannot enter any exclusive licensing deals, essentially invalidating its recent landmark deal with Apple. In addition, it must license its standards-essential patents (SEPs) to chip rivals and let the U.S. Federal Trade Commission (FTC) monitor its licensing practices for seven years.
If it stands, the ruling could slash billions of dollars off of Qualcomm’s existing and future licensing revenues. Qualcomm said that it will seek an immediate stay of the ruling and an expedited appeal.
“We strongly disagree with the judge’s conclusions, her interpretation of the facts, and her application of the law,” said Don Rosenberg, general counsel of Qualcomm.
The decision cites the potential for Qualcomm’s anti-competitive behavior to adversely affect the rollout of 5G cellular. “There is a sufficient likelihood that Qualcomm will hold monopoly power in the 5G modem chip market such that exclusive dealing agreements for the supply of modem chips could foreclose competition in that emerging market,” Judge Koh wrote.
In court testimony, Qualcomm said that it has more than 130,000 cellular patents. It claims that it has a 12- to 24-month lead in 5G silicon over rivals such as Huawei, Samsung, and Mediatek. The same day that Qualcomm struck its exclusive deal with Apple in April, Apple’s LTE chip suppler, Intel, ended plans for 5G modems.
Beyond appeals that could drag on for years, the ruling faces scrutiny from the Trump administration, which has weighed in before on 5G. Earlier this month, the Department of Justice filed an unusual “statement of interest” in the case, advising Koh not to disrupt 5G markets.
The White House aims to curb Huawei’s 5G sales, citing national security concerns. It also quashed Broadcom’s hostile takeover of Qualcomm, also raising national security concerns over 5G when Broadcom was still based in Singapore.
Defending her decision, Judge Koh detailed both Qualcomm’s behavior and legal precedents for her ruling. In a 68-page section, the ruling details Qualcomm’s anti-competitive deals with more than 16 OEMs, including Apple, Huawei, LGE, Samsung, Sony, and Vivo.
“Qualcomm has cut off OEMs’ chip supply, threatened OEMs’ chip supply, withheld sample chips, delayed software and threatened to require the return of software, withheld technical support, and refused to share patent claim charts or patent lists,” Koh wrote, calling the practices “unique in the industry.”
The decision also cites numerous incentives that hampered competition, including rebates to Apple for exclusivity and a 2018 payment of $100 million to Samsung so it would not raise antitrust issues with regulators. “Chip incentive funds result in exclusivity and near-exclusivity and, by preserving Qualcomm’s royalty rates, enable Qualcomm to continue to collect its unreasonably high royalty rates on rivals’ chips,” she wrote.
Koh devoted 10 pages of the ruling to detailing how Qualcomm refused to license at least nine chip rivals, including Broadcom, Huawei’s HiSilicon, Intel, LGE, Mediatek, Samsung, and Texas Instruments. It set what she suggested was an unfair industry practice.
“Qualcomm stopped licensing rival modem chip suppliers … because Qualcomm determined that it was far more lucrative to license only OEMs,” she wrote. “Following Qualcomm’s lead, other SEP licensors like Nokia and Ericsson have concluded that licensing only OEMs is more lucrative and structured their practices accordingly.”
Decision takes into account impact on 5G
The decision comes as 5G networks and systems are just starting a ramp, and many say they will be key to their growth. Qualcomm has at least a dozen licensees whose deals may already cover 5G, Koh wrote, citing Qualcomm’s own documents and comments.
“To permit Qualcomm to continue to charge unreasonably high royalty rates would perpetuate its artificial surcharge on rivals’ chips, which harms rivals, OEMs, and consumers, and would enable Qualcomm to continue to reap the fruits of its Sherman Act violation,” she said. “Thus, the Court finds it necessary to require Qualcomm to renegotiate those license agreements.”
Qualcomm typically charges handset makers a fraction of a handset’s selling price as a patent royalty fee —7% in a deal with Apple. In a January 2018 presentation to stockholders, Qualcomm said that its revenues more than doubled in the transition to LTE and that it was “poised to achieve substantial returns on 5G investment.”
However, Qualcomm’s royalties are “unreasonably high,” Koh wrote. “According to internal Qualcomm documents not created for antitrust investigations, other patent holders like Nokia and Ericsson have made comparable or even greater contributions to cellular standards than Qualcomm.”
The high rates “may dissuade OEMs from investing in new features that would benefit consumers because an OEM will have to pay Qualcomm additional royalties if the new features add to the handset’s price,” she added.
Koh cited a Qualcomm strategic plan from 2008 in which executives said that cellular modems drove value in past handsets, but now, value comes from new user experiences.
Analysts, some of whom were still reviewing the 233-page decision, had mixed opinions.
Patrick Moorhead of Moor Insights & Strategy called the ruling “a travesty … [with] many inaccuracies and omissions that should make a stay and appeal successful.”
For example, he said, “Judge Koh says Qualcomm created device-based licensing. It didn’t. Ericsson did.”
The ruling could lower Qualcomm’s royalties, but it won’t change the fact that most handset makers use Qualcomm chips, said Linley Gwennap of the Linley Group. “I don’t see these changes helping other chipmakers win business from Qualcomm. Most of the OEMs’ design decisions are based on the merits of the chips, not the licensing.”
Kevin Krewell of Tirias Research called the remedies “severe.” He questioned whether the FTC will continue to push the case hard under appeal, given pressure from the Department of Justice.

Hemoglobin electrophoresis is the most commonly performed test to determine a person's hemoglobin type. Widely available in the United States, it uses an electric charge to differentiate between normal and abnormal types of hemoglobin and is performed after a simple blood draw. Hemoglobin electrophoresis is performed on all newborns in more than 40 states.
Early diagnosis of SCD is critical so that children who have the disease can begin receiving the proper care as soon as possible—and so their parents can become educated about the disease. Evidence indicates that early identification of children with SCD, along with appropriate treatment, significantly improves their chances of survival during childhood.
Some groups have suggested that student and professional athletes be screened for the sickle-cell trait, based on the belief that those with the trait are more likely than those without it to develop certain complications of vigorous exercise and dehydration, such as heat stroke, exhaustion, and muscle damage due to overexertion. This notion is controversial, however, because many physicians believe that athletic coaches and trainers should safeguard all athletes, regardless of their sickle cell trait status, against complications of vigorous exercise—and that athletes with the trait should not be singled out for special treatment. Moreover, U.S. deaths due to such complications still occur predominantly among athletes without the sickle-cell trait.
SCD also can be diagnosed before a child is born with a fetal blood draw—an option some parents choose, particularly if they both carry the hemoglobin S gene, or if one carries the hemoglobin S gene and the other carries a different abnormal hemoglobin, such as hemoglobin C. This test tells parents whether their child will be born with one of the types of SCD. If SCD is diagnosed, parents may choose to terminate the pregnancy.
To optimally manage their disease, people with SCD are required to undergo a number of regular tests and monitoring procedures. Some tests are age specific; others are necessary throughout life.

Despite the growing popularity of crossover utility vehicles, or CUVs, for those with serious towing and hauling needs there are few substitutes for a full-blown, body-on-frame SUV, among them the 2008 Dodge Durango, a seven-passenger muscle machine with a rugged and distinctive style, a fairly plush interior and the option of a HEMI V8 under the hood. Although not as large as a Chevrolet Suburban, the Durango has grown large enough to compete head-on with such competitors as the Chevrolet Tahoe and Ford Expedition. Dodge’s MDS (Multiple-Displacement System) technology helps save some gas, and alternative fuel fans will find a friend in the new 4.7-liter Flex-Fuel V8 that can run on either gasoline or E85.
If you need a roomy SUV but the thought of a full-size Suburban turns you off, check out the 2008 Dodge Durango. It offers seating for seven and still has a fair amount of room for cargo behind the third-row seat. Power freaks will love the optional 5.7-liter HEMI V8 engine.
A new 4.7-liter V8 engine producing 303 horsepower replaces the previous 4.7-liter engine. The new powerplant also provides better fuel economy. The ParkView rear back-up camera system is now available.
On the road, the Durango delivers a noticeably smoother ride than its predecessor and several others in the class. The quieter interior is free from the intrusive wind and tire noise of the first generation. The steering is pretty impressive for a vehicle of this size, with good response and feedback that allow the driver to make exact lane changes and easily negotiate tight turns. Power for the base Durango is supplied by a sturdy 3.7-liter V6, with the 4.7-liter Magnum and the mighty 5.7-liter HEMI V8s as options. The base Durango is rear-wheel drive and offers the option of on-demand four-wheel drive; V8-powered Durangos have a tow/haul transmission setting that reduces gear searching by remaining in a lower gear for better pulling power.
The powerful HEMI V8 engine adds less than a thousand dollars to the price tag without a huge penalty in fuel economy.

Available on the SLT and Adventurer trims, these seats add warmth without having to add expensive leather as well.

Hyderabad: Researchers have identified five super hero foods
that will save the world, and incidentally all of them have strong
links to Andhra Pradesh.
Green gram, disease-resistant bananas, drought-tolerant maize, scuba
rice and bitter gourd are the top five foods that will not only save
the world, but also keep humanity healthy with increased immunity
against diseases. All these foods have a strong traditional link with
Andhra Pradesh, and in fact, one of them, scuba rice, has been
conceptualised in the State.
The Readers Digest, UK edition, in its recent issue listed these five
foods as the one that will save the world. Researchers in the State
have been busy working on these foods for several years to improve
their nutrition traits on one hand, and productivity on the other.
The city-based International Crops Research Institute for Semi Arid
Tropics (Icrisat) has carried out pioneering research on
drought-tolerant maize, while the World Vegetable Centre located on
the Icrisat campus is busy searching for the ideal bitter gourd with
the maximum momordicin content that could fight diabetes effectively,
besides building up immunity against a plethora of diseases.
Green gram (moong dhal or Pesarpappu) is an inseparable ingredient of
the Andhra kitchen and State-based research institutes including
Icrisat have conducted a number of research studies on this nutritious
legume. Incidentally, green gram is sown in as much as four lakh
hectares in the State.
Scuba rice is the brainchild of local farm scientists and the rice
variety was tested for the first time in the State. It can survive
under flood condition for several days without being damaged. Scuba
rice is best suited for flood-hit areas like coastal regions where
this variety can stay submerged under water for almost two weeks.
The Horticulture Research Centre, Kovvur, has conducted several
studies on disease-resistant bananas. It is also doing research on
banana germplasm and improving the nutrition content of the fruit.
“The World Vegetable Center’s improved mungbean is the result of
decades of research. It has high iron content, and its short maturity,
which allows farmers to include the crop in rice or wheat rotations.
Bitter gourd, with compounds that increase insulin sensitivity, lower
blood glucose, and help regulate glucose uptake, could provide a cheap
way to control rising rates of diabetes, particularly in developing
countries,” point out scientists at the Centre.

WELL over 1,000 people visited a public exhibition of plans for the redevelopment of Bicester Village, Tesco and Bicester Business Park last week.
Regional corporate affairs manager for Tesco, Simon Petar, said the exhibition was “extremely positive”.
He said: “Over 1,000 people attended over two days and there was overwhelming support for the plans.
“It’s good news for everybody. It will improve the highways network beyond recognition, which is what our customers have been asking for for quite some time.”
Bicester Village spokesman Miranda Markham said: “We were delighted to see so many residents visit, and those that came were largely very supportive of what we are proposing.
“The computer-generated model was hugely popular. People could see £11 million of road improvements working in real time and how the traffic would flow.
“We’re closer now to being able to deliver those very much needed road improvements.
“The next step for us will be to submit the plans and move forward with the process.”
But Bicester town councillor Les Sibley said an increase in the number of visitors to Tesco and Bicester Village once the improvements were completedwould cause more traffic chaos.
And, he added, the expansion would have a big impact on the town centre redevelopment.
He said: “If you have a new business park and Tesco, which will sell more items, that will attract more people to the area. People will go to the edge of town Tesco and Bicester Village because it offers free parking. This will have a big impact on the Bicester town centre redevelopment.”

Environment Secretary Ra-mon Paje stressed the need to conserve water at Angat Dam despite its abundance at present to ensure water availability at the height of the El Niño phenomenon early this year.
“Conservation should start this January even if Angat’s water level is high,” he said.
He noted that the National Water Resources Board (NWRB) will soon review Angat’s water situation and the latest El Niño forecast so government can allocate water from the dam accordingly for the coming months.
Rain-fed Angat supplies water for irrigation, power generation and Metro Manila’s needs.
Last year, NWRB reduced allocation of Angat water for Metro Manila and suspended normal supply of irrigation water.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) had warned that El Niño may intensify to a new record level, further prompting government to implement contingency measures.
In late 2015, however, Angat Dam’s water situation improved as rainfall from several tropical cyclones increased its reserve.
On Saturday, the dam’s water level stood at 213.50 meters, higher than the flood season high water level of 212 meters.
But Paje said that the public should still conserve water because of the possibility that there could be no rain for months.
Pagasa’s forecast released this week indicates Angat Dam will likely face water woes in the first semester of the year. The dam’s water level will likely dip to 208 meters by February, the weather bureau said.

Coal and nuclear electricity generation off to a rocky start in 2018
Energize Weekly, February 14, 2018
The prospects for coal-fired and nuclear electricity generation got off to a shaky start in 2018 with a projected record number of coal unit closures and three nuclear power plants set for shutdown.
The Trump administration has been trying to find ways to bolster the two sectors. It proposed giving subsidies to plants in wholesale markets, contending they added to the resiliency and security of the grid. In January, the Federal Energy Regulatory Commission rejected the plan.
Energy Secretary Rick Perry is reportedly weighing the use of emergency orders to keep some coal-fired plants online.
Despite these actions, about 15,000 megawatts (MW) of coal-fired capacity will close this year, more than double the closures in 2017, according to an analysis by the Institute for Energy Economics & Financial Analysis (IEEFA), a non-profit, foundation-funded group.
“In electricity generation—the key market for coal—the industry is increasingly uncompetitive and is losing market share,” David Schlissel, lead author on the report and IEEFA director of resource planning analysis, said in a statement.
In major wholesale electricity markets, coal-fired generation has slipped since 2009 to 32 percent from 70 percent in the PJM, which covers Mid-Atlantic and Midwest states; to 46 percent from 64 percent for the Midcontinent Independent System Operator (MISO), which serves all or parts of 15 states and Canadian provinces.
The federal Energy Information Agency (EIA) in its February Short-term Energy Outlook projects annual consumption of coal by the utility industry dropping by 15.5 million tons between 2018 and 2019 to 646 million tons.
The EIA said that the coal plants retired since 2008 were relatively old and small, averaging 52 years and 105 MW. But the IEEFA analysis identifies eight plants ranging from 1,184 MW to 2,308 MW slated to close between 2017 and 2020, with most closing this year.
As for nuclear plants, in January, NextEra Energy said its 647 MW Duane Arnold nuclear plant in Palo, Iowa, will be shuttered when its contract to supply Alliant Energy runs out. FirstEnergy Corp. said its Davis-Besse nuclear plant in Oak Harbor, Ohio, may also be headed for early closure.
In February, Exelon said it would close its Oyster Creek plant in Lacey Township, N.J., the oldest operating commercial nuclear plant in the U.S., in October, a year ahead of schedule.
The pressures on coal-fired and nuclear generation are much the same. The IEEFA listed them as increased competition from low-cost renewables, low natural gas prices and competition from natural gas-fired generators, low energy market and capacity market prices and nearly flat demand for electricity.
An analysis released in January by Massachusetts Institute of Technology researcher Jesse Jenkins placed most of nuclear power’s problems at the foot of natural gas. Jenkins analyzed the impact of flat demand, wind power and natural gas on the 19 nuclear plants in the PJM market.
Jenkins noted that due to new drilling techniques, market prices for natural gas dropped 72 percent between 2008 and 2016.
“The drop in the price of natural gas appears responsible for the majority of observed declines in electricity prices across the 19 PJM nuclear plants over this period . . . 50 to 86 percent of the observed changes,” Jenkins said.
There appears to be little relief. The EIA projects the spot price for natural gas, at the Henry Hub, a major distribution point, to remain below $3.50 through 2050.
In January, NextEra announced in its quarterly earnings that it was taking a $258 million after-tax impairment on the Duane Arnold facility, Iowa’s only nuclear plant, “reflecting the company’s belief that it is unlikely the project will operate after 2025.”
The plant has a license to operate through 2034, and NextEra said it will continue to seek a contract extension.
Alliant, however, is hedging its position. “The cost of wind energy right now has really dropped as well as the cost of natural gas to be at levels where they are competitive and have never been before,” Justin Foss, a spokesman for Alliant told the Cedar Rapids Gazette. “We are continuing to pursue different options for our customers to make sure that they get the best value.”
FirstEnergy also said that unless bolstered by state subsidies, its Davis-Besse plant would also likely close. James Pearson, the company’s chief financial officer, told the Toledo Blade the plant cannot cover its costs in the PJM wholesale electricity market.
Illinois and New York State have already approved as much as $10 billion in subsidies to keep nuclear plants in those states open for the next decade.
On Feb. 2, Exelon announced that it had reached an agreement with New Jersey state regulators to close Oyster Creek this coming October.
“The plant faces a unique set of economic conditions and changing environmental regulations that make ending operations in 2019 the best option for the company, employees and shareholders,” Chris Crane, Exelon’s chief operating officer, said in a statement.
In addition to low natural gas prices, nuclear and coal face as much as 100 gigawatts of wind and solar coming online by 2022, according to S&P Global Market Intelligence, as prices decline and performance rises.
The squeeze placed on coal and nuclear in the wholesale markets was underscored by an IEEFA analysis of bids into the PJM capacity market. PJM operates the market to ensure it has adequate generating capacity.
In the May 2017 auction PJM conducted for the 2020-2021 delivery year, prices were about 23 percent lower than those set in the 2016 auction. Some of the bids were 54 percent below the capacity prices set in the 2015 auction for the delivery year 2018-2019.
So, the capacity price dropped from $100 a MW-day in 2019-2020 to $76.53 MW-day for 2020-2021.
“This means that a typical 600 MW coal-fired plant that will receive $33 million in capacity revenues during the 2018-2019 delivery year will earn only $15.4 million in the 2020-2021 delivery year. This represents a sharp drop in revenues and could render unprofitable previously profitable units,” the IEEFA analysis said.


Sweeping modernization called for by former NRC Official
Washington DC — Former U.S. NRC Commissioner Jeffrey S. Merrifield called for a comprehensive new framework (PDF file) for Advanced Reactor licensing reform in an issue brief outlined at the National Press Club on 2/231/6.
Merrifield, who served two terms with the Nuclear Regulatory Commission, chairs the Advanced Reactors Task Force of the U.S. Nuclear Infrastructure Council, a nuclear industry business consortium. The Council is the founder and organizer of the Advanced Reactors Technical Summit, most recently held at the Oak Ridge National Laboratory earlier this month. Merrifield is a Partner with Pillsbury Winthrop Shaw Pittman law firm.
Merrifield noted that a confluence of environmental, energy security and competitiveness considerations are accelerating the compelling need for the expedited development of Advanced Nuclear Reactors in the United States and worldwide.
“Deployment of this new generation of reactors,” he said, “will require a new model, one that is more dynamic and capable of forming private-public partnerships in support of private-sector innovation driven initially by private-sector investment.
“The current framework of U.S. government policy, legislation, regulation and requirements, research and development support, and fee-based licensing is more aligned with past development efforts than what is needed for the future to commercialize a new generation of Advanced Reactors,” Merrifield said.
“This is particularly true of the U.S. Nuclear Regulatory Commission (NRC) licensing process, which presents one of the largest risk factors confronting private developers of Advanced Reactors as it does not accommodate a staged investment approach as the technology development and licensing risks are addressed and resolved.
“Congress should consider significant policy changes. It should provide additional resources to both agencies as well as direct them to focus and mobilize their resources and expertise on the goal of expanding nuclear energy options with Advanced Reactors.
Both the DOE and NRC must be proactive in developing their capabilities and engaging with the Advanced Reactor community. The unique features being trail blazed by Advanced Reactors justify an updated and modernized NRC design review and licensing process,” added the former Commissioner.
Among the 11 specific reforms proposed in the licensing modernization framework are:
• A mandate for a 36-month Advanced Reactor licensing review by the NRC;
• General revenue funding to allow the NRC to waive the fees for the review of Advanced Reactors through their final design approval and for regulatory infrastructure and staffing to review and approve Advanced Reactor technology designs;
• Establishment of a phased design review and licensing process that would provide intermediate milestones towards a design certification that would include an early determination of licensability to enable continued development of designs without requiring a complete design to be submitted upfront;
• Development of a risk informed licensing process for Advanced Reactors that recognizes their reduced source term risk and avoids the unnecessary implementation of regulatory requirements that are more appropriate for large light water reactor technologies;
• Resolution of generic policy issues pertinent to Advanced Reactors within two years.
The issue brief’s conclusion:
“It is time to make dramatic changes in the way we pursue, support and license Advanced Reactor technologies to achieve the full measure of their promise and the success the nation needs for the future. While this will require a sustained focus and investment of resources by government, the return on investment will be pivotal in ensuring the U.S. maintains its technological leadership in nuclear energy’s vital and carbon-free source of clean energy while providing jobs, economic competitiveness and energy security while improving our nation’s environment and health.”

According to the Energy Information Administration, production of natural gas from shale formations has increased approximately 30 percent from 2006 to 2012. This increase, due to advancements in drilling technologies, has caught the EPA off guard and left it with limited knowledge about the amount of pollutants entering the groundwater, surface water or air.
This poses an issue because states rely on the EPA’s information when issuing permits or determining if someone breaks a rule, and these decisions are being compromised if they are reliant on non-existent or questionable water quality or air emissions data. This realization is also a bit concerning considering hydraulic fracturing releases chemicals such as methane, the main component of natural gas and also a potent greenhouse gas.
The EPA has agreed it needs to improve its data, and is working with the appropriate parties to ensure the continued expansion of oil and natural gas drilling is done safely and responsibly. This situation shows that being prepared to handle big data like this is vitally important. Locus’ EIM and ePortal software are Cloud-based platforms for effectively managing air emissions, as well as hydrofracking data of any kind, water, groundwater, SPCC, and compliance information. By managing this information in one, easily accessible, web-based platform it is easier to stay on top of essential data collection, and to make sure your data quality is at its best.


3.3 Sediment transport processes over benthic ecosystemsGo back to program
About the theme
The fundamental aim of this project was to build on ‘conventional’ knowledge of sediment transport over bare sandy beds to develop new transport formulations applicable to a broad range of bottom types. Critically, it is shown here that conventional sediment transport models break down dramatically in canopy environments. These models typically either (1) ignore the flow attenuation provided by the canopy or (2) assign an enhanced bed stress to canopy regions (to diminish the flow), a correction which ultimately enhances sediment erosion (relative to adjacent regions without canopies). Both of these errors can result in massive over-prediction of the capacity for sediment to be mobilised within the canopy, and thus significant underestimation of the threat from dredging activities.
- To further our understanding of sediment dynamics in bioclastic environments by allowing for conversion of existing grain size distributions to settling velocities and thus allowing for the hydrodynamic properties and transport modes of grains to be established.
- To assess the ‘rough-wall’ boundary layer flow dynamics and turbulent shear stresses over a coral reef flat.
- To quantify the grain-size distribution and concentrations of suspended sediment in the water column.
- To evaluate how modifications to the mean and turbulent flow structure alter suspended sediment grain sizes, SSCs, and SSFs over a rough coral reef flat, including the implications for making robust sediment transport predictions within reef environments.
- To assess the variability of sea-swell waves, infragravity waves and mean currents at different locations and timescales in a fringing reef.
- To quantify the magnitude as well as the spatial and temporal variability of suspended sediment concentrations.
- To evaluate how the suspended sediment concentrations that were observed relate to the prevailing hydrodynamic processes.
- To build predictive capability for the two key hydrodynamic parameters, bed shear stress and near-bed turbulent kinetic energy, that are expected to govern sediment erosion and deposition in coastal canopies.

Luisa's Vegan, Colombia 66%
This Colombia bar is part of an amazing project. Luisa’s motto is that Luisa need high quality beans to make award-winning chocolate. For that and alongside the University of Nottingham, they are using science and DNA sequencing to discover what makes a great Bean. Using her scientific knowledge, Luisa travelled to Colombia to share and teach her knowledge with the farmers. She is involved in a program to empower the female farmers to use their land for cacao, coined “the Peace Crop”, rather than cocaine and take ownership of their land.
The first crop when Luisa arrived in Colombia made a bland and bitter chocolate, soon after using Luisa’s knowledge to implement the necessary means to cultivate premium cacau, everyone started noticing the difference in the Colombia bars and today this bar is an awarded chocolate by the The Great Taste, The International Chocolate Awards and The Academy of Chocolate Awards.

I purchased a 2013 Lincoln MKX in January 2013. It currently has 12,500 km. I noticed a cut on the sidewall of a tire and would like to have it replaced. However, I am being told that I should replace tires in pairs. Someone else told me I would have to replace all the tires or the AWD would not operate properly. Before I go to the tire store, could you please advise me if I have to replace one, two or all four tires. – Martin, Toronto
Can you ease into re-tirement by changing one tire at a time? Probably not – it depends on how much wear you have on the other three, says the Rubber Association of Canada.
"If you had a brand new car, had only driven it for a couple of days and were replacing it with the same kind of tire, I'd say you could replace just the one, no problem," says Ralph Warner, director of operations for the association, which represents Canada's tire manufacturers. "But without seeing them, it's impossible to judge."
Just a few thousand kilometers on the road could wear down the old tires enough that a new tire – even if you managed to find the exact same model as the others – could have noticeably deeper treads. A good tire shop would be able to tell you if the difference is subtle enough to let you replace just one.
"There's no firm and fast rules, it's a judgment call," Warner says.
Here's why. Because it still has full treads, the new unworn tire would be larger than the rest, which could make the traction control system (TCS) think the other tires are spinning.
"Traction control systems sense revolution of the tires and compare one to another, they respond when they find one tire is slipping," Warner says. "You run the risk of tricking the TCS into acting when in fact there's nothing wrong."
The TCS and Anti-lock Braking System (ABS) use speed sensors in each wheel. The system doesn't know that one of the tires is a different size. It just knows that the tires are spinning at different speeds, and that it needs to get them to spin at the same speed. Most systems do that by triggering the brakes.
Often, you can replace two tires instead of all four. With the MKX, Ford says it's usually fine to replace tires in pairs, since the ABS and TCS can compensate if the front and rear tires aren't worn equally.
Christine Hollander, Ford of Canada's communications manager says the AWD system isn't the problem here - it shouldn't be fooled into activating when it doesn't need to by tire wear alone. But the replacement tires should be the same size, and have the same speed rating and load index as the others.
While changing two is fine, four new tires guarantee that all the tires start out with the same amount of traction – and traction keeps your car in the road, Warner says.
If you combine two badly worn tires with two new tires, you could get the same trouble you'd get if you put two winter tires on a car instead of four.
With the stickier tires on the front and all seasons on the back, you could get oversteer, meaning the car turns more sharply than you want it to, which could steer you into an oncoming vehicle. If the new tires are switched to the back, you could get understeer, which is when the car doesn't steer enough. You could drive straight though a corner instead of turning.
Understeer is the lesser of the two evils (there aren't usually oncoming Mack trucks in ditches). If you do get just two new tires, make sure the newer tires are on the back, Warner says.
"Bottom line, find a tire shop you trust and get their advice," he says. "I know people get concerned about whether the service guy is trying to just get money out of them... but your car's designed to have equal traction on all four wheels."

How are you feeling about your chances of a pay raise in the next 12 months? Are you feeling more concerned lately about layoffs at your company? In the latest Glassdoor Employment Confidence Survey, conducted online on its behalf by Ipsos Media, Glassdoor takes a current pulse on how employees and job seekers are feeling – not only about their expectation for a pay raise, but other factors, too. The survey monitors four key indicators of employee confidence: salary expectations, job security, re-hire probability and company outlook. Highlights from this latest report are included below:
Optimism Around Company Outlook & Salary Increases
Employee optimism related to pay raises within 12 months, as well as overall company outlook continues to rise during the first quarter of 2012. In fact, for the first time in four years, more employees expect a pay raise than those who do not – 43% of employees expect a pay raise in the next 12 months, while 38% of employees do not, and 19% report they don’t know. A year ago (first quarter of 2011), employee optimism over pay raises was at one of its lowest levels in four years – with only 35% of employees optimistic of a pay increase within 12 months.
The optimism around pay increases may be tied to the fact that more employees believe their company’s outlook is improving. Nearly half (46%) of employees believe their company outlook will be better in the next six months, up six points from the prior quarter, reaching the highest level ever, since Glassdoor began conducting this survey in 2008.
In addition, men continue to be more optimstic than women when it comes to company outlook, but the gap has narrowed in the past year. In the first quarter of 2012, 48% of men felt their company’s outlook will improve within six months, compared to 45% of women. One year ago (the first quarter of 2011) 50% of men were optimistic that their company outlook would improve within six months, compared to just 28% of women.
Concern About Layoffs Edges Up, While Optimism Trips Over Job Market Prospects
While much of this latest survey is encouraging, at the same time, more employees are concerned about layoffs, not only for themselves, but also for co-workers. Nearly one in five (19%) are concerned they could be laid off in the next six months, up two points from the fourth quarter after declining the two preceding quarters. One-third of employees (33%) are also concerned co-workers could be laid off in the next six months, rising five points from the fourth quarter of 2011.
To add to rising layoff concerns, employees are growing less optimistic about their job prospects should they lose their current position. The survey shows that 37% of employees are confident in their ability to find a job matched to their experience and compensation levels, if they were to lose their current job, within six months. This figure has dropped to its lowest since the fourth quarter of 2010.
It’s also worth pointing out that more than one-third (36%) of those unemployed but looking for work say they believe it is likely they will find a job in six months, up six points from the fourth quarter of 2011, to its highest level since this survey began in 2008.

Rencia Lourens RADMASTE Centre Using the CASIO fx-82ZA PLUS for functions in the FET band
Some remarks A calculator is a tool. Learners should Know where answers come from. Understand mathematics. Teachers should Teach the mathematics. Explain the reasoning behind why the calculator methods work. BUT the calculator can (and should) become a tool to assist.
CAPS Functions form 35% of the Grade 12 paper 1, 45% in Grade 11 and 30% in Grade 10 (CAPS). The calculator can be used to support the calculations needed to draw and interpret the graphs of the functions.
So how can I use this as a teacher to enhance understanding? Some thoughts The meaning of symmetry The minimum value The meaning of a plotted graph The shape of a quadratic function Just checking – the turning point is (2; -5)
xf(x) -5-43 -4-31 -3-21 -2-13 -7 0-3 1 2 3-3 4-7 5-13 y-intercept Turning point should be here No x-intercept?
Seems as there are no x- intercepts. Focus on turning point first. Will be between x=1 and x=2. The turning point is below the x-axis. All the graph values are below the x-axis. So no x-intercepts. x 1 1.25-0.8125 1.5-0.75 1.75-0.8125 2
xf(x) -5-119 -4-75 -3-39 -2-11 9 021 125 221 39 4-11 5-38 y-intercept Turning point should be here x-intercept should be here
Somewhere between x = -2 and x = -1 the one x-intercept should lie and somewhere between x = 3 and x = 4 the other x-intercept should lie. So we are going to look at smaller domains and smaller steps.
