Pokiez Casino offers new players up to 15% rakeback for the first week. In practice, this means that at best you will get back 15% of the money you invested – won or lost.
Rakeback differs from rakeback, traditionally used in online casinos, in that you get your money back from all the money you bet, not just from the money you lost. The amount of rakeback at pokiez log in depends on how much you bet.
However, you will receive at least five percent of your first bets. After that, the rakeback amount will gradually increase to that 15 percent.
Pokiez Casino – Promotions and Tournaments
More enjoyable online casino games are offered. For example, various changing offers and an exciting bonus bot called Rainbot in English Sade.
This bot appears in the rather popular Pokiez Casino chat room about every ten minutes and rewards players.
Pokiez Casino – VIP Program
The Pokiez Casino VIP Program is different from the usual loyalty points where you can earn daily credits to play casino games.
The number of credits depends on your daily level, which in turn depends on how much you play. The three levels in order of merit are as follows: Silver, Gold and Emerald.
Pokiez Casino Game Account?
Signing up for a Pokiez Casino account is a little different than what you normally do. First, enter your email address, name and come up with a password. After that, you can already log in, but you still need to provide additional information about yourself in order to manage your money.
To increase your winnings, Pokiez Casino reserves the right to request additional proof of your identity. Such documents may include, for example:
- Proof of identity (e.g. passport)
- A scanned copy of a credit/debit card in the user’s name.
- Financial account
- Birth certificate
- Check or other proof of payment
- Other supporting documents
Pokiez Casino Game Selection
Pokiez Casino has over 2,000 slot machines for everyone, including more than 30 traditional game manufacturers including all traditional favorites like NetEnt, Play ‘n’ Go, and Yggdrasil.
In addition, there are interesting small gaming studios, as well as exclusive slots like the military-themed Pokiez Casino Strike, created by Caleta Games for Casino. Worth a look!
On the Live Casino side, you’ll find a total of 81 gaming tables from four different providers. Thus, the live tables from Evolution Gaming , Microgaming , Pragmatic Play and One Touch are quite versatile. Live Casino’s game selection includes a long list of traditional live casino games such as blackjack, Texas Hold’em, roulette and baccarat. Also available are popular live games from Evolution Gaming, such as Crazy Time and Monopoly live .
Pokiez Casino – Roulette, high-low and craps
Let’s highlight them separately under the headings Roulette, Hi-lo and Crash. These are, in fact, constantly running quite dynamic and exciting games. This online casino calls them Pokiez Casino Originals.
Although these first two games themselves are not original to this online casino, as they have been played on the world stage.
Roulette, like the other two games, works all the time and is a nice place to visit, it always makes little difference if you enter even euros or a couple of reds. A new round starts about every ten seconds, and the table is always in use.
Thus, high-low is a traditional card game in which you guess whether the next card will be bigger or smaller than the one on the table. This has made Pokiez Casino a pretty exciting game. Crash, on the other hand, is a pretty simple game mathematically.
There is an arrow that runs along the curve and stops at a certain point. The stopping point determines the payout ratio at which you get your bet back. Crash uses the SHA256 algorithm as the basis for its game. SHA comes from the words Secure Hash Algorithm.
So, it’s an IT encryption technology and so on. KVG, that is, look up google, please!

Find out the way to take care of every thing from behaviour to well being questions with our professional pet recommendation. Goldendoodle’s make wonderful assistance dogs and have been used as guide dogs, service canines, remedy canines and sniffer dogs. The Standard Poodle originated in Germany as a water retrieving dog, particularly bred for the aim of hunting waterfowl. This breed is commonly depicted donning haircuts which are regarded as all about trend, however their uncommon style is actually excess of that.
Of course, these can all be kept in check and at bay by offering your dog with all necessary care. Ensure plenty of exercise, a wholesome and balanced diet, heat and comfy sleeping quarters, and so forth. By caring on your pet you guarantee their health is in prime.
How A Lot Does A Mini Goldendoodle Cost?
We anticipate our breeders to show honesty, integrity, and fairness in coping with different owners, breeders, purchasers of puppies and most of the people. We really feel that the deliberate manufacturing of “Golden Doodles” profoundly violates that trust. The Golden Retriever, as a purebred dog, comes from generations and generations of breeding canines with a typical gene pool and a attribute appearance, temperament and performance.
After a hard day of play, the Goldendoodle will happily relax on the sofa and chill with the household. This man will do everything that he probably can to get at your plate. On the plus facet, he’s a minimum of cordial and might be happy to swap his dish for yours! The smaller poodles may be aggressive to individuals outdoors their households or to other canine. They should have early socialization to different individuals and pets and a firm hand in training.
F1 Minature Goldendoodle Puppies On The Market
The curls of your Goldendoodle’s coat will begin to turn out to be extra noticeable during this period and those with straighter coats will develop their waves. All their reserves throughout their first few weeks will be centered on growing and as such they will sleep as a lot as 90% of the time. They will feed between 6 and 8 times a day and during their first week it’s expected that they may double their delivery weight. They will have their first experiences of being petted as mother cleans them by licking their coats and they’re going to instinctively respond to heat, touch and odor. During the primary couple of weeks pups need to be stimulated to go potty as they’re unable to manage this themselves. They are additionally unable to manage their own physique temperature which is why snuggles with mum is so essential.
PuppySpot Goldendoodles is the best place in California to find the proper Teacup Goldendoodles for you and your beloved ones. There are loads of resources online if you wish to purchase a Teacup Goldendoodle puppy. A fast search on Teacup Goldendoodle Puppies on the market close to me will list quite a few results in each major space or location.

At the beginning of April, the occupants of a building on rue Dominici had to leave their accommodation urgently because of a risk of collapse. Building work is expected to begin in September.
A “risk of imminent collapse of the building”: this is what we can read on the municipal decree dating from April 1, hung on a barrier in rue Dominici, in the old center of Cahors. In order to avoid a tragedy, the tenants of the two apartments in the building concerned had been urgently relocated.
As of March 25, the owners had called on a company to support the facade facing Dominici Street. Five months later, the props continue to support the frame. During the summer, they were even reinforced. Entering the building, whose main entrance is at 107 rue Blanqui, parallel to rue Dominici, is still prohibited until further notice. At the beginning of May, the tenants were authorized to enter the building exceptionally to proceed with their move.
A specific procedure to follow
Work is expected to begin in September. But before that, a particular procedure had to be followed: intervening on a medieval building implies certain rules. “A project manager has been appointed by the owners. He is responsible for making proposals. As we are on what is called a remarkable heritage site, an SPR, the perimeter is protected”, explains Isabelle Hidalgo, director of general and legal affairs of the city of Cahors and Greater Cahors. As provided for in the legislative framework, an ABF, architect of the buildings of France, must then decide before any intervention. “Either this architect will validate the proposals, or he will make prescriptions”, develops Isabelle Hidalgo. This procedure is in progress. In the meantime, “the city regularly monitors [la façade, NDLR]. The owners are very mobilized on this file. They’re doing whatever it takes to make it happen,” she continues.
The work should then mainly concern the resumption of the masonry of the facade overlooking rue Dominici. According to the decree of April 1, the building presents a “very significant detachment of the lintel of the door, a large crack between the wooden door and the lintel, crumbling, falling materials and an absence of plaster as well as holes on the main facade which has a domed appearance”.
But this exterior work does not mean that the building will immediately become habitable again: a second phase of work will have to be launched, to carry out interior redevelopment.

When would you use a regression model?
Regression analysis is used when you want to predict a continuous dependent variable from a number of independent variables.
If the dependent variable is dichotomous, then logistic regression should be used..
How do you tell if a regression model is a good fit?
In general, a model fits the data well if the differences between the observed values and the model’s predicted values are small and unbiased. Before you look at the statistical measures for goodness-of-fit, you should check the residual plots.
Why do we use two regression equations?
In regression analysis, there are usually two regression lines to show the average relationship between X and Y variables. It means that if there are two variables X and Y, then one line represents regression of Y upon x and the other shows the regression of x upon Y (Fig. 35.2).
Why is it called regression?
The term “regression” was coined by Francis Galton in the nineteenth century to describe a biological phenomenon. The phenomenon was that the heights of descendants of tall ancestors tend to regress down towards a normal average (a phenomenon also known as regression toward the mean).
What is a good R squared value?
Any study that attempts to predict human behavior will tend to have R-squared values less than 50%. However, if you analyze a physical process and have very good measurements, you might expect R-squared values over 90%.
How do you write a regression model?
A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).
What is the purpose of regression equation?
A model regression equation allows you to predict the outcome with a relatively small amount of error. In this model, Yi represents an outcome variable and Xi represents its corresponding predictor variable. The equation also contains numerical relationships between the predictor and the outcome.
What does a regression equation tell you?
A regression equation is used in stats to find out what relationship, if any, exists between sets of data. For example, if you measure a child’s height every year you might find that they grow about 3 inches a year. That trend (growing three inches a year) can be modeled with a regression equation.
What does regression model mean?
Regression is a statistical method used in finance, investing, and other disciplines that attempts to determine the strength and character of the relationship between one dependent variable (usually denoted by Y) and a series of other variables (known as independent variables).
Which regression model is best?
Statistical Methods for Finding the Best Regression ModelAdjusted R-squared and Predicted R-squared: Generally, you choose the models that have higher adjusted and predicted R-squared values. … P-values for the predictors: In regression, low p-values indicate terms that are statistically significant.More items…•
What is a regression model example?
Simple regression analysis uses a single x variable for each dependent “y” variable. For example: (x1, Y1). Multiple regression uses multiple “x” variables for each independent variable: (x1)1, (x2)1, (x3)1, Y1).
What is an example of regression problem?
These are often quantities, such as amounts and sizes. For example, a house may be predicted to sell for a specific dollar value, perhaps in the range of $100,000 to $200,000. A regression problem requires the prediction of a quantity.
What are the two regression equations?
2 Elements of a regression equations (linear, first-order model) y is the value of the dependent variable (y), what is being predicted or explained. a, a constant, equals the value of y when the value of x = 0. b is the coefficient of X, the slope of the regression line, how much Y changes for each change in x.
How do you explain multiple regression models?
Multiple regression generally explains the relationship between multiple independent or predictor variables and one dependent or criterion variable. A dependent variable is modeled as a function of several independent variables with corresponding coefficients, along with the constant term.
What is simple regression analysis?
Simple linear regression analysis is a statistical tool for quantifying the relationship between just one independent variable (hence “simple”) and one dependent variable based on past experience (observations).
What is the difference between regression and correlation?
The difference between these two statistical measurements is that correlation measures the degree of a relationship between two variables (x and y), whereas regression is how one variable affects another.

Artistic expressions are vital in civic education and public enlightenment in democratic societies. In ensuring an open and democratic governance, artists play an important role, addressing political, social and economic issues in ways that appeal to emotions, promote citizens’ right to information and public participation. For artists to function effectively in this role, artistic freedom is a precondition. According to UNESCO [.pdf], artistic freedom is defined as “the freedom to imagine, create and distribute diverse cultural expressions free of governmental censorship, political interference or the pressures of non-state actors. It includes the right of all citizens to have access to these works and is essential for the wellbeing of societies.”
Although violations of artistic freedom are a global phenomenon, as evidenced in The State of Artistic Freedom 2019 Report [.pfd], artistic expressions with dissenting views are brazenly suppressed in Sub Saharan Africa by politicians, clerics, community leaders and others who feel challenged in their bid to hold on to power and influence by artists. Musicians, composers, filmmakers, comedians, playwrights, visual artists, poets and other artists increasingly struggle to create critical works as a result of restrictions imposed by the state, religious establishments, traditional practices and social customs. Artists have faced and continue to face censorship, threats, attacks, harassments, arrests and prosecutions arising from these obstacles.
Former UN Special Rapporteur on Cultural Rights, Ms Farida Shaheed, embarked on a comprehensive study on these issues. She presented the landmark Report of the Special Rapporteur in the field of cultural rights: The right to freedom of expression and creativity [.pdf] in 2013, which became the benchmark upon which new global reports have been developed to track these restrictions to artistic freedom worldwide. The former UN Special Rapporteur, among other recommendations, urged UN Member States to review legislations and practices restricting the right to freedom of artistic expression in compliance with their obligations to respect, protect and fulfil this right, and raised concerns about the need for urgent discussions in several areas identified in the report.
The challenges to artistic freedom are worsened by limitations to judicial independence in a number of African states. Although many African countries practice democracy, the overall independence of courts is less than the global average [.pdf]. Despite the diversity in regimes under which African courts operate, many countries in the region share similar characteristics. Courts in Africa are vulnerable to undue interferences such as threats, attacks, bribery and removal of judges by the executive arm of government. Undue interferences also occur in the form of informal networks arising from political affiliations, ethnic and religious ties.
In Uganda, widespread criticisms of the government have been strongly reflected in artistic expressions in recent times. Through music and other art forms, many artists, including popular reggae dancehall star Bobi Wine, raised concerns over a 2018 law by President Yoweri Museveni’s administration, which removed the upper presidential age limit to allow the eligibility of the 74-year-old president to run for a sixth term in 2021. Ugandan activist, academic, feminist and poet, Stella Nyanzi, was one of such strong creative voices that have criticised the president and his government. In September 2018, she posted a poem on Facebook using a metaphorical expression to describe the birth of the President and his mother's vagina as part of the broader criticisms of his perceived oppression of the country for over 30 years. She was arrested in November 2018. On 2 August 2019, Nyanzi was found guilty of “cyber harassment” and sentenced to 18 months imprisonment. She, however, was expected to serve only nine months having already been incarcerated nine months awaiting trial. The judgement prompted unrest within the court's premises where a plastic bottle was reportedly thrown at the magistrate and a confrontation averted between supporters of Nyanzi and the police.
Similarly, cultural activists in Nigeria and around the world condemned what was widely criticized as an unjust imprisonment of a Kano-based musician Mohammed Yusuf. Known by his stage name AGY, the artist was arrested on 18 June 2019 and sentenced barely two days after for allegedly insulting Kano State governor Abdullahi Ganduje in a song. The alleged insult relates to the verses of the lyrics composed in Hausa language, which says, “The Kano governor has already turned blind. I swear, what you did is hurting us. For lucre, the governor is more than a thief. For lucre, the governor can sell out Goggo [his wife].” The governor is widely believed to be corrupt. In October 2018, video clips of the governor receiving what appeared like US dollar notes went viral. It was said to have been recorded by a spy camera and published by an online medium Daily Nigerian to press for investigations into allegations of bribe payments from contractors.
In what appeared as window-dressing to create a favorable impression of the prosecution, AGY was also charged with two counts of releasing a song and music video without the permission of the Kano State Censorship Board. He was sentenced to two years imprisonment, with an option of 50,000 naira fine for each of the two counts, totalling 100 000 naira ($280). However the first count of "insulting" the governor had no sentencing option other than imprisonment. The artist is currently serving his jail term.
In October 2019, Guinean reggae artist Elie Kamano [pictured at the top of this post] was reported arrested for participating in a peaceful protest opposing the attempts to secure a third term by President Alpha Condé. He was sentenced to one year imprisonment alongside other protesters. According to Guinee News, the reggae star and other imprisoned activists were released on 28 November 2019 after the first appeal hearing. The case was adjourned to 5 December 2019.
The popular saying in Nigeria that “the judiciary is the last hope of the common man”, including for an artist who uses creative expression to challenge the status quo, is fast becoming a fallacy in many African countries. The examples above, which are just a few of more than 40 similar cases documented so far in the course my research as an O’Brien Fellow in Residence at McGill, the question of judicial independence in Africa raises concerns. There have been numerous controversial judgments by courts across the continent in 2019 that have fallen short of international human right standards.
It is also noteworthy that judicial independence is negatively impacted by outright disregard for court orders by the executive arm of government and their agencies. On 6 December 2019, armed security operatives reportedly stormed a federal high court in Nigeria to forcefully re-arrest a journalist, Omoyele Sowore who was on trial in less than 24 hours after being granted bail. The judge and court officials reportedly fled the courtroom for their own safety. Such brazen disregard for rule of law creates an atmosphere of fear and undermines the independence of the judiciary.
Many of the prosecutions observed in my research of cases involving artists were politically motivated. The judgements appear to have been influenced contrary to the general principle that “for judgement to be fair, it must also be seen to be fair”. The danger in politically motivated prosecutions and influenced judgements is immeasurable. It fosters impunity by politicians to abuse justice system and use prosecution to give legitimacy to oppression and tyranny. One of the key objectives of my research is to provide verifiable evidence that cultural activists need in advocating for justice. To protect artistic freedom in Africa and empower artists to exercise their civic responsibilities, citizens and civil society must stand up and demand for an independent, transparent and accountable judiciary.
Without an independent judiciary, there will be no true art, and no rule of law.
The image used to illustrate this post is a still from a video by Guinean reggae artist Elie Kamano, who was arrested for participating in a peaceful protest opposing President Alpha Condé's attempts to secure a third term, and whose case is ongoing.

text: BACKGROUND: Inflammation contributes to the pathophysiology of major depressive disorder (MDD), and anti-inflammatory strategies might therefore have therapeutic potential. This trial aimed to determine whether adjunctive aspirin or rosuvastatin, compared with placebo, reduced depressive symptoms in young people (15-25 years). METHODS: YoDA-A, Youth Depression Alleviation with Anti-inflammatory Agents, was a 12-week triple-blind, randomised, controlled trial. Participants were young people (aged 15-25 years) with moderate to severe MDD (MADRS mean at baseline 32.5 ± 6.0; N = 130; age 20.2 ± 2.6; 60% female), recruited between June 2013 and June 2017 across six sites in Victoria, Australia. In addition to treatment as usual, participants were randomised to receive aspirin (n = 40), rosuvastatin (n = 48), or placebo (n = 42), with assessments at baseline and weeks 4, 8, 12, and 26. The primary outcome was change in the Montgomery-Åsberg Depression Rating Scale (MADRS) from baseline to week 12. RESULTS: At the a priori primary endpoint of MADRS differential change from baseline at week 12, there was no significant difference between aspirin and placebo (1.9, 95% CI (- 2.8, 6.6), p = 0.433), or rosuvastatin and placebo (- 4.2, 95% CI (- 9.1, 0.6), p = 0.089). For rosuvastatin, secondary outcomes on self-rated depression and global impression, quality of life, functioning, and mania were not significantly different from placebo. Aspirin was inferior to placebo on the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF) at week 12. Statins were superior to aspirin on the MADRS, the Clinical Global Impressions Severity Scale (CGI-S), and the Negative Problem Orientation Questionnaire scale (NPOQ) at week 12. CONCLUSIONS: The addition of either aspirin or rosuvastatin did not to confer any beneficial effect over and above routine treatment for depression in young people. Exploratory comparisons of secondary outcomes provide limited support for a potential therapeutic role for adjunctive rosuvastatin, but not for aspirin, in youth depression.

EXTROVERTSpace Propulsion 05 AE6450 Fall 2008 Lecture #5 Nozzles Types of nozzles Expansion Ratio criteria Nozzle heat transfer and materials issues In this lecture we will cover:
EXTROVERTSpace Propulsion 05 NOZZLES The function of the rocket nozzle is to convert the thermal energy in the propellant into kinetic energy as efficiently as possible, in order to obtain high exhaust velocity along the desired direction. The mass of a rocket nozzle is a large part of the engine mass. Many of the failures encountered in rocket engines are also traceable to failures of the nozzle – historical data suggest that 50% of solid rocket failures stemmed from nozzle problems. The design of the nozzle must trade off: 1.Nozzle size (needed to get better performance) against nozzle weight penalty. 2.Complexity of the shape for shock-free performance vs. cost of fabrication

EXTROVERTSpace Propulsion 05 Nozzle Types The subsonic portion of the nozzle is quite insensitive to shape – the subsonic portion of the acceleration remains isentropic. The divergent nozzle is where the decisions come into play. Conical Nozzle Easier to manufacture – for small thrusters Divergence losses: Exit velocity is not all in the desired direction. Bell Nozzle Complex shape Highest efficiency (near axial flow at exhaust) Large base drag during atmospheric flight after burnout Plug Nozzle or Aerospike Nozzle (linear or annular) (X-33, VentureStar, 1960s concept ) Altitude compensating (see Chang 3-30c) Expansion- Deflection Nozzle (E-D) Shortest nozzle of the “enclosed” types.

EXTROVERTSpace Propulsion 05 Bell Nozzle Complex shape Highest efficiency (near axial flow at exhaust) Large Base Drag during atmospheric flight after burnout A true bell nozzle is contoured to minimize the turning (compression) shock losses at the wall as the flow expands, but still turning the flow towards an axial exhaust. Note that the flow may still be under-, over- or fully-expanded at the exit, and hence shocks / expansions may exist downstream.

EXTROVERTSpace Propulsion 05 Comparison of bell and cone nozzles For the same , we would expect A bell nozzle, while more complex to build, will generally yield a more efficient exhaust than a cone in a shorter nozzle length. Same nozzle efficiency factor can be reached with about 70% of the length of a cone nozzle. Alternatively, efficiency factor can be increased from about 98% for a cone to about 99.2% for a bell of the same length
EXTROVERTSpace Propulsion 05 Types of Nozzles Types of nozzles Expansion Ratio criteria Nozzle heat transfer and materials issues In this lecture we will continue the discussion on nozzles:
EXTROVERTSpace Propulsion 05 Annular Nozzles Expansion-Deflection Nozzle and Plug Nozzle Substantially shorter than conical or bell nozzles for the same thrust and area ratio. Design-point performance is nearly as good. Off-design performance is better under conditions where conventional nozzles would be over-expanded. Common feature: Free shear layer bounding nozzle flow.

EXTROVERTSpace Propulsion 05 Contraction Ratio vs. Throat diameter Also, the contraction rate can be empirically determined as a function of D t. Chang gives a range from 2 to 5 for the e c for low thrust engines (smaller D t ), and from 1.3 to 2.5 for higher thrust engines (Larger D t ). Knowing L* and e c for a given A t and propellant, we can estimate the required combustor length, Lc, for the cylinder section.
EXTROVERTSpace Propulsion 05 Sources of losses 1. We have already discussed the effect of non-axial flow at the nozzle exit. Other sources of losses 2. Friction: Small in large engines, but can be significant for large . 3. Heat loss - Exit velocity is lower than expected due to enthalpy losses (fairly small). Non-uniform flow at exit - can be a big effect if the nozzle flow is separated inside. - Open cycle mass flow losses Note that the mas flow rate through the throat, which is what goes through the nozzle, may be less than the propellant consumption rate, because some of the propellant is diverted to run the pumps or not recaptured after use as coolant.
EXTROVERTSpace Propulsion 05 Losses (continued) 4. Nozzle chemistry (recombination) Recombination can actually increase C* above the frozen flow nozzle assumption as species recombine if equilibrium flow is assumed. if frozen flow is assumed and Taken together, all of these corrections will yield a “real” lambda of 0.9 to 0.98 (Humble pp.206) depending on the cycle, nozzle, throat losses, etc.

A Canadian Bison Association survey that was conducted in the first quarter of 2018 shows continued growth in the sector.
Executive director Terry Kremeniuk said the association does its own census because the federal census numbers are gathered in June.
“That’s probably the lowest point in the year in terms of the number of animals in the country,” he said at the 2018 CBA convention.
According to the 2016 census, there were slightly more than 119,300 bison, along with 975 producers and an average herd size of 122.
He said when he took those numbers and adjusted for animals born, slaughtered and exported, he believes the population last Jan. 1 was about 150,000 animals.
Given efforts like Bison One Million and optimism in the industry, Kremeniuk told producers the long-term future is bright.
The CBA survey was first done in 2014 and updated last year. The first survey talked to 343 producers, but only 126 participated in 2018.
Still, Kremeniuk found a fairly stable industry with an average herd size of 257 in 2018, down about a dozen animals. The average number of breeding bulls was 12.8, compared to 12, and the average number of cows calving was 92.5, down slightly from 95.
However, he found it interesting that in 2014, 42 percent of respondents were planning to expand while last year 68 percent said that was a goal.
“Those types of numbers raise questions about what is the growth of the herd,” he said.
“It’s very difficult to say at this point in time.”
Further analysis of the numbers found that about a third of the cow herd is less than five years old, while about 60 percent is between five and 17 years old. Ten percent of the cow herd is still productive at older than 17 years.
The average bull age is six.
The weaning percentage is 83, while the average weaning weight of bulls is about 470 pounds and heifers are about 425 pounds.
“As time goes on we’re getting more and more industry data, and hopefully this information is helpful in terms of you planning your business,” Kremeniuk said.
He said the CBA is getting more questions from other stakeholders such as lenders and policymakers about the data it is collecting.
“Any data that we can share with those folks increases the profile and makes sure the interests of the industry are reflected,” he said.

Scam artists might be targeting visitors from cruise ships because they know passengers cannot afford to be delayed for fear of missing a ship's departure. A group from Brooklyn that disputed a taxi fare and refused to pay were driven to the police station by their driver. They ended up in a brawl with police and were arrested while their ship sailed without them. They now face a criminal trial. Whether the taxi driver tried to rip them off is less important than the lesson: Research rates and negotiate the fare in advance - and be prepared to pay if confronted with a rip-off.

Brief of the Case
Delhi High Court held In the case of CIT vs. Morgan Securities & Credits Pvt. Ltd. that any changes in the audited financials like for e.g., the ‘regrouping’ of shares in the present case, if at all permissible, has to be preceded by a legally acceptable procedure adopted by the Assessee, and in any event prior to the finalization and signing of the audited balance sheet for a particular financial year.
Facts of the Case
Assessee is a private limited company engaged in the business of trading and finance. For the AY 2005-06, the Assessee filed its return of income on 31st October 2005 declaring a total income of Rs.3,75,88,170 which comprised of business loss of Rs.(-)1,08,73,143, net short term capital gain of Rs.4,84,61,310 and long term capital gain of Rs.51,92,406. The AO noticed from Clause 11 of the tax audit report (TAR) in Form 3CD that there has been a change in the method of accounting affecting the profitability of the company. The inventory of shares valued at Rs. 9,83,45,399 had been treated as investment in the current year.
According to the AO, the only motive for this undue change in this year appeared to be lowering the tax incidence and taking undue benefit of the exemption from tax on long term capital gains under Section 10(38) of the Act and concessional rate of tax @ 10% on short term capital gains under Section 111A. Treating the entire shares held by the Assessee as stock in trade, the AO treated the resultant profit from the sale of shares in the sum of Rs.10,22,58,060 as business profit in the hands of the Assessee and directed it to be brought to tax as such.
Held by CIT (A)
The CIT (A) held that the transactions under consideration were on investment account and not stock in trade and directed the AO to amend the computation of total income accordingly.
Held by ITAT
ITAT held that the AO had accepted the stand of the Assessee that shares were held as investment for AY 2004-05 as well. According to the ITAT, the AO could not have taken a different view for AY 2005-06 particularly since there was no material on record to justify it.
Held by High Court
The record of the AO for AY 2005-06 reveals an important fact concerning the regrouping of the investment by the Assessee for the year ending 31st March 2004. It is seen that the audited balance sheet of the Assessee for the year ending 31st March 2005 contains two columns giving the figures as on 31st March 2004 and 31st March 2005. It is seen that in this balance sheet the figures given for the “inventory‟ as on 31st March 2004 have sought to be shown as per ‘regrouping’. However, balance sheet as on 31st march 2014 were not produced.
It is, therefore, not clear whether after the signing of the audited balance sheet as on 31st March 2004 by Directors and CA any resolution was passed by the Board of Directors of the Assessee deciding to treat as investment, the shares shown therein as stock in trade. This is an important aspect which does not appear to have merited attention by the CIT (A) or even the ITAT.
It is unacceptable that after an audited balance sheet of a company for a financial year is signed by its Directors and statutory Auditors, and submitted to the statutory authorities, including the ROC and the income tax authorities, the figures in such balance sheet for the closing stock of shares can simply be altered subsequently by adopting the device of regrouping by the Assessee, even by a Board resolution. That is a process unknown to the law.
Even from the point of view of principles governing statutory accounts, such change cannot be simply give effect to in the balance sheet and P&L account for a subsequent year. For instance, such a change, as was sought to be made by the Assessee in the instant case, to the value of the closing stock of shares by treating it as investment instead of stock-in-trade, would affect in the balance sheet and P&L accounts for at least two financial years. It is doubtful if this can at all be done particularly if the statutory authorities including the ROC and the income tax authorities have already been provided with such signed audited accounts for a particular financial year.
Considering that above aspects having not been examined by the ITAT, the Court sets aside the order of the and remands the said appeal to the ITAT for a fresh consideration keeping in view the above aspects. The ITAT is urged to call for the complete details of the records both from the AO as well as the CIT (A) and any further relevant particulars to arrive at a correct decision.
Accordingly, appeal disposed of.

Kistos spuds UK exploration well, considers future drilling program for oil field offshore the Netherlands
(WO) – Kistos, a low carbon intensity oil and gas producer pursuing a strategy to acquire assets with a role in energy transition, provided an update on its drilling activities in the Netherlands and the United Kingdom.
The Benriach exploration well, located on block 206/05c (Kistos 25%) West of Shetland and operated by TotalEnergies E&P UK, has been spudded by the Transocean Barents. The operator estimates it is targeting P50 prospective resources of 638 Bcf (160 Bcf or 28MMboe net to Kistos).
The well is expected to complete in Q3 2023. The dry hole post-tax cost net to Kistos is forecast to be roughly £2.5 million ($2.71 million) as a result of Kistos’ tax paying position and the enhanced investment allowances from the Energy Profits Levy.
After arriving on location at the Q10-A gas field (Kistos 60%) in November 2022, the Valaris 123 rig recently departed after safely completing its work program. The results of the campaign were mixed.
This was due to mechanical issues arising from utilizing the existing well stock rather than reservoir performance issues. The Kistos technical team, with the assistance of external consultants, is undertaking a detailed evaluation of the results and future production enhancement options.
Future work programs are being considered and could include the drilling of further Zechstein clastics wells in 2024 in combination with development drilling at the Orion oil field. Engineering design work has now been completed to enable the installation of two more risers on the platform, which would allow it to host additional wells.
The Orion field continues to progress through the Concept Select Phase, which Kistos is undertaking with the assistance of Rockflow Resources.
Andrew Austin, Kistos' Executive Chairman, said, "We are excited that the Benriach well is underway. It is an important milestone for the company with the potential to add significant reserves.”
He added, “I would like to congratulate our team in the Netherlands on the safe completion under difficult weather conditions of the operational work program. The process of fully evaluating the results of the campaign is ongoing, and will inform the planning of future work programs, including the potential operational synergies with the Orion oil field development.”

Throughout the month of October, Metrograph, the relatively new art-house-flavored theater on New York’s Lower East Side, is screening movies made in the 1990s that are queer in one way or another. The offerings range from highly political films and documentaries that address the pressing issues that gay Americans faced during the decade to mainstream Hollywood films that helped normalize the lives of gay people to mainstream audiences. The survey is titled “Queer 90s” with 29 films screening and includes Derek Jarman’s 1993 film Blue, the last he would make before dying of AIDS–related complications, three of Sadie Benning’s shorts, Gus Van Sant’s My Own Private Idaho (1991), Celluloid Closet (1995), which looks at the AIDS activist Vito Russo’s research of queerness throughout the history of movie making, and more mainstream gems, like Basic Instinct (1992) and Cruel Intentions (1999).
The series kicks off tonight with a screening of Todd Haynes’s Poison (1991), which will be introduced by Christine Vachon, one of the film’s producers, who most recently produced Haynes’s 2015 Oscar-nominated film Carol. Another thing to look forward to, taking place on Wednesday, October 12, is an introduction by, and Q&A with, director Tom Kalin and Hilton Als, who co-wrote the script for Swoon (1992). I spoke with the team behind the series, Jacob Perlin, Metrograph’s director of programming, and Michael Lieberman, its head of publicity, to find out more about the series.
This interview has been edited and condensed.
ARTnews: How did you come up with the idea for the “Queer 90s” film series?
Michael Lieberman: It was something that I’d been thinking about for a long time, just as somebody who came of age in the ’90s, watched a lot of these films in the ’90s, and was trying to figure out a way to reconcile all the different pieces that were there. They don’t all necessarily talk to each other or communicate with each other as works, but they all came out at the same time and I feel like that decade acted as a bridge. We attempt to treat this whole series as an anthology of different voices in a period of time that was tumultuous. It was a transition period from the beginnings of queer civil rights to the present day.
Jacob Perlin: I’ve always been interested in a type of programming that’s simultaneously film history and social history. It’s only years later where trends are more evident and you can see the great cultural impact that these films had collectively, even if they weren’t exactly in dialogue with each other at the time.
Lieberman: The ’90s are also a thing right now. There are a lot of films in there that we like that aren’t necessarily important cultural milestones but were a part of that landscape that I feel are equally important.
Perlin: And films that define the way culture was looking at these issues at the time. That’s how a film like Basic Instinct fits in. It was very much a part of the cultural conversation.
Lieberman: There were talks about boycotting that film by gay and lesbian groups in the ’90s.
Perlin: If you’re attempting to examine the way homosexuality was depicted in American cinema in that decade, you include a film like Basic Instinct. It’s just part of the cultural climate of that period, both the film being made and the reaction against it and its popularity, everything. It fills out the picture.
I noticed that you included a lot of art-slanted films in the series, like Derek Jarman’s Blue. What was the reasoning behind that?
Lieberman: When we were discussing this, Blue was always at the top of the list. This was a film made by a man dying of AIDS. He had lost his sense of sight at the time, so he could no longer direct films. If you see the film, it’s the color, the Yves Klein blue with dialogue over it. That film is one of the great films of all time because it’s made out of the absolute need to express yourself. … [The films] all served a collective purpose, which is representation of a queer voice.
How did you go about choosing the list?
Lieberman: Well, we had a very large list.
Perlin: But it’s not going to be a hundred film series; it’s going to be a month-long series, so how do you do it. One thing is that none of the filmmakers are represented by more than one title.
Lieberman: We also narrowed things down thematically. We couldn’t show five of the same types of films. We wanted to make sure that every type of gay film was represented and the major artists were all there. But I do think it gives people a big enough picture of what the landscape was like. It could have been a 200-film series.
What kind of role did the producers and production companies play in creating this cultural landscape that you talked about earlier?
Perlin: A vast majority of these films were independently produced and independently distributed, in some cases by the filmmakers themselves, or by very small companies that were the only companies that were willing to take chances on films like this. What you’re seeing is that it was a period of time where the distributors were small companies and individuals and played a real role in getting these films out.
Lieberman: You can talk about Zeitgeist Films putting out Poison.
Perlin: Poison is the perfect example.
Lieberman: On top of that Poison was hugely controversial. Jesse Helms denounced it on the Senate floor, which is an insane thing to think about now.
Do you think these films and going to the movies acted as a form of community for queer people?
Lieberman: I think that cinema is a meeting place. I think that for a lot of queer people in the ’90s going to a movie about a sympathetic queer character by a queer filmmaker is in a way a place where you can be—where you can see something like yourself, in an environment that’s constructed closer to the world you live in. When I heard that something way playing in the art theater in my hometown about a gay character, I’d see every single one of these films. You would also hear about things in a different way, in magazines, in newspapers and wait for it to come for you. Eventually, you’d find it and it’d be an event. This was something you were anticipating.

In an interview conducted after he watched the first atomic test, he quoted from the Bhagavad Gita: "'Now I am become Death, the Destroyer of Worlds.' I suppose we all felt that way." When asked in an interview at Rochester University seven years after the Alamogordo nuclear test whether that was the first atomic bomb ever to be detonated, his reply was, "Well, yes, in modern history." "Ancient cities whose brick and stonewalls have literally been vitrified, that is, fused together, can be found in India, Ireland, Scotland, France, Turkey and other places. There is no logical explanation for the vitrification of stone forts and cities, except from an atomic blast. Another curious sign of an ancient nuclear war in India is a giant crater near Bombay. The nearly circular 2,154-metre-diameter Lonar crater, located 400 kilometres northeast of Bombay and aged at less than 50,000 years old, could be related to nuclear warfare of antiquity. No trace of any meteoric material, etc., has been found at the site or in the vicinity, and this is the world's only known "impact" crater in basalt. Indications of great shock (from a pressure exceeding 600,000 atmospheres) and intense, abrupt heat (indicated by basalt glass spherules) can be ascertained from the site.

Studies of gene expression profiling have been successfully used for the identification of molecules to be employed as potential prognosticators. In analogy with gene expression profiling, we have recently proposed a novel method to identify the immunophenotypic signature of B-cell chronic lymphocytic leukemia subsets with different prognosis, named surface-antigen expression profiling. According to this approach, surface marker expression data can be analysed by data mining tools identical to those employed in gene expression profiling studies, including unsupervised and supervised algorithms, with the aim of identifying the immunophenotypic signature of B-cell chronic lymphocytic leukemia subsets with different prognosis. Here we provide an overview of the overall strategy employed for the development of such an "outcome class-predictor" based on surface-antigen expression signatures. In addition, we will also discuss how to transfer the obtained information into the routine clinical practice by providing a flow-chart indicating how to select the most relevant antigens and build-up a prognostic scoring system by weighing each antigen according to its predictive power. Although referred to B-cell chronic lymphocytic leukemia, the methodology discussed here can be also useful in the study of diseases other than B-cell chronic lymphocytic leukemia, when the purpose is to identify novel prognostic determinants.

COLUMBUS, Ohio (AP) — Ohio Supreme Court Justice Pat DeWine has recused himself from hearing a would-be gubernatorial candidate’s lawsuit challenging his disqualification from the ballot.
DeWine filed his recusal Wednesday in the case of Democrat Jon Heavey. Heavey is a Cleveland-area physician and venture capitalist who entered the race on the Feb. 7 filing deadline. He has put $1.5 million of his own money into his campaign.
DeWine is the son of another candidate in the race: Republican Attorney General Mike DeWine. Mike DeWine’s running mate, Secretary of State Jon Husted (HYOO’-sted), is among parties Heavey has sued.
Heavey wants the high court to reverse Husted’s decision removing him from the ballot.

BAMAKO (Reuters) - Gold ore production in Mali jumped 15 percent in 2012 to 50.272 tonnes, from 43.5 in 2011, as miners followed through with
expansion plans despite a political crisis and a war, the government said on Thursday.
Output from Mali's southern gold mines is expected to expand further to 57 tonnes this year, said Djibouroula Togola, the technical advisor in charge
of production at the West African nation's Mines Ministry.
"Despite the crisis, we exceeded our forecasts in 2012. The industrial mines produced 46.272 tonnes and the artisanal miners produced four tonnes,
bringing total output to 50.272 tonnes," he told Reuters.
"In 2013, we expect industrial production of 53 tonnes and artisanal production of four tonnes. So the forecast for 2013 is around 57 tonnes," he
The increase comes despite turmoil in the country - Africa's No. 3 gold producer behind South Africa and Ghana - which suffered a coup in March and
where French and regional troops are helping the army combat Islamist rebels in the north.
All of the country's gold production is in the south.
Gold companies with mines in Mali - including Randgold Resources, AngloGold Ashanti and Avion Gold - have been publicly playing down the risks of the
crisis to production and shipping.
Togola said the construction of a new mine by Canadian miner Robex Resources, expected to produce two tonnes per year over 10 years, had further
brightened the outlook.
Malian officials have said the chaos has also left its second economic pillar, cotton, largely untouched.
Where is the Mansa Musa of todays Mali.

Reflection | As we turn to chapter 5, Peter heads into the homestretch of his first letter to scattered Christians throughout Asia Minor. In our passage for today, Peter will begin by addressing the elders. He then will widen his circle of focus to include the younger members in the community. He will conclude by providing counsel for all believers. We will look at the bulk of these instructions to the collective group next time.
First, Peter begins by speaking to the elders: “To the elders among you, I appeal as a fellow elder and a witness of Christ’s sufferings…” (verse 1). “Elder” comes from the Greek word, “presbyterous” and biblically, it refers to those are called and serve in leading the local church. Contrary to popular Christian thought, age is not a scriptural criterion for occupying this role. However, maturity, experience, and moral integrity, which often come with age, are the specific qualifications spelled out in the New Testament (see 1 Timothy 3:1-17, Titus 1:5-9).
Peter makes his appeal to these leaders as one who is also an elder. Let us recognize there is much more to Peter’s resume than this designation. Even though he points to his experience as an eyewitness, Peter could have more explicitly referenced his authority as an apostle – as one of the original twelve disciples who first followed Jesus. He also could have spoken about his missionary journeys and decisive moments at the forefront of the start of the early Church. Right from the start, Peter is modeling the overall posture he is encouraging these elders to adopt – one of humble service rather than elevating oneself above others.
Appealing to his empathy with these elders in their task, Peter frames their shared job description through the lens of a familiar scriptural image: “Be shepherds of God’s flock that is under your care…” (verse 2). The imagery of shepherding is richly biblical, permeating Israel’s story. Israel is God’s flock and God himself is their shepherd (see Psalm 23:1-4; 28:9). Jesus intentionally associated Himself with this role and thus proclaimed Himself to be both the Messiah and God in the flesh when he declared that he was the Good Shepherd (see John, chapter 10. Peter points to this understanding of Christ later in the passage as he talks of “the Chief Shepherd” who will return later (verse 4).
Like a shepherd, an elder’s role is one of supervision. The Greek word used literally means “to take oversight,” or “to look diligently after.” Elders are those who watch over the community. It’s a role that requires paying attention to what is happening within the fellowship as well as being aware of what’s going on in the lives of those who make up the local church. Elders, however, are not merely spectators. They keep an eye out in order to anticipate and initiate in the tending of needs – in helping and guiding the flock.
Peter stresses that serving as elder is not something one ought to do “because you must, but because you are willing, as God wants you to be…” Those in the church should not take on a role of leadership to fulfill the expectations of others. Leadership in the Body of Christ always must be a willing response to being called by the Holy Spirit. The Lord desires that one serves just as one gives – willingly and therefore, wholeheartedly. A person forced into spiritual leadership by the pressure or demands of others cannot and will not serve as God intends. He or she will either abuse or be abused in their role – individually burning out or burning others and thus driving them away from God and the Church.
Hence Peter goes on to add a caution against “pursuing dishonest gain” and “not lording it over those entrusted to you but being examples to the flock” (verse 3). Those who answer the call of leadership in the church must be eager to serve for the sake of the Great Commission and the Kingdom of God alone. Our role, those of us who are elders or leaders, is to serve. Personal gain – be it material goods, psychological affirmation, or a desire for control – must not be one’s motivation as an elder.
Rather than seeking the enrichment or aggrandizement of oneself, a Christ-like leader ought to aim to guide others in their Christian walk. Peter rounds out his instructions by indicating this kind of leadership is about showing, not merely telling. An elder’s primary responsibility is to be a living witness to other believers of how to follow Jesus – particularly in the face of hardship, suffering, and persecution.
Elders are those who lead by first following Jesus. Peter makes this clear by reminding those to whom he is writing that the community of believers belongs to God and not to its human leaders. Peter understands both himself and the “fellow elders” to whom he speaks as being “under-shepherds.” All leaders in the Church but especially those who serve as elders must remember they serve not on the basis of their own authority by that of Christ Himself – the One who alone can gather and restore God’s scattered people.
Peter’s instructions prove that it is easy to lead others badly, by serving reluctantly, or for personal gain, or in a domineering and controlling way. True Christian leadership is the call to serve. Jesus taught about it this way: “The greatest among you is to be the servant of all” (see Matthew 20:20-28). In order to serve like this, the answer to the call to shepherd must always first be understood as a call to be shepherded. Elders who are not regularly yielding, abiding, and being cared for by Jesus should not be leading anybody. Leaders in the Church lead well – in a manner that is healthy and effective – not because of their great faith but because of Jesus’ faithfulness.
Peter learned this lesson the hard way. It all came together for him over a charcoal fire on a beach in the aftermath of his three-fold denial of Christ. When Jesus was asking Peter “Do you love me?” and then in response to each of Peter’s affirmations told him to “Feed my sheep,” Jesus was communicating a crucial truth. Peter’s ability to feed Christ’s sheep would not come from Peter’s undying loyalty to Jesus but rather from Jesus’ faithful love toward Peter that always would restore and sustain Peter despite his disloyalty.
Leadership is never an easy task. It is often a thankless one. Some have said, “Leadership is its own reward.” Peter seemingly agrees when he assures the elders to whom he is writing, when Jesus returns at the end of all things, “you will receive the crown of glory that will never fade away” (verse 4). The exact meaning of this phrase is unclear. But if nothing else, Peter is assuring elders that their service and sacrifice for Christ are never in vain and will not be forgotten. The reward for leading like Jesus is that we become more like Christ in our character and person. In other words, we draw closer to who we are meant to become.
Peter now turns to those who are younger, spiritually speaking, in the community, and calls for them to “submit yourselves to your elders” (verse 5). This simple and concise direction falls in line with a theme Peter has unpacked throughout this letter. Christians live together under several layers of authority. God in Christ, our Creator and our Redeemer, is the ultimate authority over us. In our service to the Lord, we exist in a broken world that is temporarily held together by various forms of human authority – by governing bodies in the public realm or family structures in the home.
Similarly, within the Church itself, there is a configuration of organizational leadership. Those who are called to shepherd need to be followed by the flock. As members of the Church, we are to follow Jesus by following those whom Christ has called to lead us. Both a church without leadership and a church that will not submit to biblical leadership is a church that is liable to propagate a damaging witness to Jesus and to do harm to others. As followers of Jesus, we are not called to blind allegiance but rather to evaluate and hold our leaders accountable. Church leadership, however, is not accountable to our personal preferences or desires. Church leadership is to be held accountable to teaching and direction that are demonstrably from God’s Word and Spirit and centered in Christ.
Peter extends his appeal not on the basis of a hierarchy of power but according the scriptural principle of mutual submission. He instructs both elders and members, young and old alike: “All of you, clothe yourselves with humility toward one another.” Properly understood, the biblical understanding of humility is not about self-hatred or putting oneself down. As C.S, Lewis once wrote, “Humility is not thinking less of yourself, but thinking of yourself less.”
In other words, biblical humility is about deferring to God and not ourselves as the center of the universe. Humbling ourselves is to live rightly before the Lord – to glorify Him through how we treat others – with respect, with dignity, with love.
Notice how Peter describes the act of humbling ourselves. It is a choice rather than something that instinctively comes from within us. Submitting to one another is like putting on a change of clothes. We have to take off our normal “outfit” – the posture out of which we normally operate. And what is our typical demeanor? The Bible is repetitive on this count. Either out of fear and insecurity or arrogance and presumption, our default attire is our pride. No one likes their pride being wounded. All of us have a hard time accepting when we are wrong – and even when we do accept it, many of us still believe we ought to be right!
Unchecked pride became our go-to designer wear that moment back in the Garden when we started to convince ourselves we knew better than God. And it’s remained in fashion for humanity ever since. Peter, however, quoting Proverbs 3:34, reminds us changing our attire is necessary “because God opposes the proud but shows favor to the humble.” Our refusal to promote and serve others above ourselves is not just a denial of the dignity and the needs of those around us; it is an affront to God – the One in whose image we are all made. To live for ourselves is to live opposed to God because we were created to live for God by existing in concert and in care of each other.
Pride is resistant to grace – both the need for it and continuing to rely upon it. Still, it can be hard surrendering the thickness of the skin of our ego. Practicing humility is putting on much more intimate wear. It exposes us and makes us vulnerable rather self-protected. We resist humility and safeguard our pride because we are afraid of becoming insignificant, of going unrecognized, of making ourselves nothing. Anticipating this, Peter directs us to “Cast all your anxiety on him because he cares for you” (verse 7).
Just a verse earlier, he assures us that when we humble ourselves, we are not ultimately unguarded but rather we are putting ourselves “under God’s might hand.” Such a continual step of faith and trust will not go unanswered by our good, good Father. In yielding the work of seeking our own glory and instead seeking to serve and work for the good of others, at exactly the right time, Peter promises, God “will lift us up.” As Christians, we must never fear death – even the death of our pride in service to others. Because, thanks to Jesus, when we die to ourselves, our resurrection in Christ is always assured.
Consider & Discuss | Do you lead and follow with humility? What anxieties do you feel when submitting to authority? How does this instruction about elder relationships help you understand God as the Chief Shepherd? Through Peter’s words about leadership and humility, what is God asking of you personally? How do you see pride impacting your relationship with God? With other people? How is pride connected to anger, bitterness, envy, lust, anxiety, and other besetting sins? What anxieties or worries are you carrying that you need to put in the Lord’s hand so that you can be lifted up by Him?
Prayer Focus | Heavenly Father, I come before Your throne of grace and mercy asking You to lead me through Your Word and Your Spirit in humbling myself – first, before You and then, before others. I confess that many times I am well-pleased with myself to the point of arrogance and presumption towards You and my brothers and sisters around me. I confess that my pride also can be driven by my fears or my longings about what others think of me. Teach and guide me to relinquish my pride – to let my ego and my self-centeredness fall by the wayside so that I may instead be clothed in Your compassion and love. Give me a deeper sense of humor so that I can laugh at myself rather than take myself so seriously. When I am tempted to view myself as greater than anyone, snuff out the tinder of my self-importance by overwhelming me with the magnitude of Your glory and grace. Help me to remember that when I humble myself before You, I am trusting You and You will always lift me up. Amen.

As Cape Fear River Watch prepares to hold its annual LakeFest, the water quality of the Wilmington lake continues to cause concerns
WILMINGTON – Kermit the Frog's old catchphrase is still true at Greenfield Lake: it ain't easy being green.
Years after the popular Wilmington lake was diagnosed with a litany of water quality problems, including an infestation of algae and the presence of fecal matter, Greenfield Lake is still on the state’s list of impaired waters -- a designation it's held since 2014.
This Saturday, Cape Fear River Watch will host LakeFest, its annual celebration of the lake, inviting residents to explore the urban lake, take guided eco-tours, and learn about the ecology of the 250-acre city park that surrounds the lake.
But for those who study the lake, its health is still a source of concern that needs to be addressed.
Mike Mallin, a research professor at the University of North Carolina Wilmington (UNCW), said the lake’s issues have only gotten worse with time. Each year, it is besieged by a blanket of algae that, once it dies each fall, leaves behind an even bigger problem than decreased visibility.
“The natural bacteria multiples like crazy,” Mallin said. “They suck the dissolved oxygen out of the water.”
A dozen years ago the city took several measures to address the annual bloom, including the installation of aerators to break it up and adding sterile carp to munch on the excess aquatic weeds.
More recently, Wilmington Mayor Bill Saffo said the N.C. Department of Transportation’s replacement of 70-year-old culvert under Burnett Boulevard/South Front Street that allows for excess water to drain faster and updated stormwater and residential construction runoff regulations have all helped the situation.
But the mayor said there's more to be done.
“It is very important we work to keep making improvements to the lake," Saffo said. "As the area around it is redeveloped, more people are going to be visiting it."
But Mallin, who has been testing the lake for two decades, said the nitrogen and phosphorus levels are still high, which set the stage for the annual bloom of the deep green and blue algae from the water's surface to the lake floor.
“The amount of blooms has gone drastically higher,” he said. “The city will have to implement a plan to reduce the amounts of nitrogen and phosphorus. We know a significant amount is coming in from the streams.”
Mallin’s student Nick Iraola recently completed research into what the streams are dumping into the lake. He found Jumping Run Branch stream, which extends as far east as 17th Street, and Squash Branch stream, the closest to the park's boathouse, contributed the most pollutants.
One major factor in the lake’s health is the urbanization of the area surrounding it, which contributes runoff pollutants to the water -- including fecal matter.
Even something as simple as pet feces left abandoned around the lake can be washed in by rainfall, Mallin said, adding that picking up after pets is one of the simple things residents can do to help improve the lake's health.
On the government side, Mallin said he presented the research paper's findings to city staff members this week and hopes the report prompts some action. Possible strategies to improve the lake’s health could be strengthening the vegetative buffers along streams or installing more advanced options that could absorb some of the nitrogen and phosphorus.
Building constructed wetlands to treat the contaminated water before it reaches the lake could also prove beneficial, Mallin said.
“The city is very aware of the issues,” he said. "My hope is this research will guide the city on what to do next."
