Dangers Of Teeth Whitening

Submitted by: Jenna Smith

The amount your teeth discolor sometimes depends on the kinds of food you eat or the medicines you take. It doesn’t always depend on how many times in a day you brush. Dentists teach proper brushing techniques because they say that improper brushing strokes could do more harm than good especially when done briskly with a hard-bristled brush.

Most of us have a fear of going to a dentist because of which our teeth suffers from various problems. It is true that you should brush your teeth at least twice a day but you should also visit a dentist once every six months. Most of us have a very busy schedule and taking time out to visit a dentist is often very difficult that is why our white suffers. Whiter teeth give a healthy and attractive look but faded or yellow teeth look pretty dirty and untidy they actually spoil the entire look of a person. It is not that difficult to maintain bright and white teeth when so many cosmetic teeth whitening solutions are available in the market.

Horizontal Brushing, according to the hygienists, cause scraping of enamel that leads to exposure of the dentin which causes sensitivity and appearance of a darker yellow shade. It looks very undesirable especially today when people may judge you on the appearance of your teeth.

When your teeth are yellow, it looks like something is wrong – they may look decayed and not very attractive to many. Yet, it is not quite right to equate yellow teeth with unhealthy teeth – although the correlation may be there. Appearances can be deceiving.

Bleached teeth could be unhealthy teeth but they look spotless. How many people who bleach often are facing gum recession? This is a question to ask the next time you consider bleaching your teeth.

There are many products on the market intended for whitening. But how do you know if the use of such a product will guarantee the health of your teeth and gums?

Bleaching can reach right into the tooth pulp and in the worst cases can actually kill the tooth. Therefore, the tooth will eventually turn brown and require a crown. Is that the result you are looking for?

Please exercise caution when considering the possibility of whitening your teeth. Patients often want to use budget friendly yet safe and effective products. Brushing alone may not be the answer and teeth whitening products can strip enamel thus leading to hypersensitivity, according to research. Some people have observed that prolonged use of toothpaste with whiteners make there teeth sensitive to cold beverages and to a blow of air directly on their teeth.

Upon looking at pictures of people after a whitening session, the enamel looks really chalky white and rough. One caption says that the teeth are extremely sensitive at this time.

The teeth may look several shades lighter but does that really look attractive? A little tooth discoloration may be fine as long as your teeth are not decaying and your gums are healthy. If the teeth are healthy, then maybe the right answer is to leave them as they are. The bleached look just does not appear natural.

If bleaching or whitening harms the health of the teeth or gums, is it really worth it? Be careful when bleaching teeth.

Afghan women’s rights official shot dead

Tuesday, September 26, 2006

Safia Ahmed-jan, the director of the Afghan Ministry of Women’s Affairs for the Khandahar province and an advocate of women’s rights and a strong critic of the Taliban‘s repression of those rights, was shot dead by unidentified gunmen outside her home in Khandahar city in southern Afghanistan on Monday.

Safia Ama-jan, as she was known locally, is the first woman official to be targeted by the Taliban-led insurgency since it was deposed in 2001.

Safia Ahmed-jan taught at a girls’ school and was a high-school principal in Khandahar prior to the Taliban’s 1996 rise to power in Afghanistan. When the Taliban regime banned education for girls and forbade women from working outside the home, she ran an underground school for girls at her home, said her son Naqibullah, speaking to the Associated Press.

After the Taliban government was overthrown in 2001, Ahmed-jan became the provincial chief for women’s affairs in 2002, when the ministry was established and has since then held that position, worked for women’s rights and particularly, championed the cause of educating girls. Her secretary, Abdullah Khan told Associated Press that among her most successful projects were the vocational training schools she opened in Khandahar, where almost 1000 women were taught baking, tailoring and other skills.

Ahmed-jan has also been fiercely critical of the repression of women during the Taliban rule, in a region that has remained conservative and emerged as a hotbed of the Taliban’s insurgent activity. Her requests for personal security guards and transport went unheeded by the government, according to local media reports, though her nephew, Muhammad Asif told the New York Times that Ahmed-jan preferred to keep a low profile and used a taxi or public transport even though her office maintained cars and drivers.

Ahmed-jan was shot dead outside her house at about 7:30 a.m. local time (UTC+4:30) on Monday, as she left for work in a taxi. The gunmen are believed to have left scene on a motorcycle, and tyre marks have been found by the police, said the provincial governor Asadullah Khaled, who visited the scene of the attack.

Ahmed-jan was shot four times with a pistol, Muhammad Haidar, who worked in her office told the New York Times. Mohammad Nader, the head nurse at Khandahar’s main hospital where Ahmed-jan was taken to, confirmed to the Chicago Tribune that she was shot four times, including once in the head.

She was about 65 years old.

Accounts of the shooting are sketchy, several reports suggesting no one witnessed it. However, one man, identified as Allaudin told Al Jazeera that he saw two men on motorcycles waiting on the road, who attacked Ahmed-jan as she left her house.

A spokesman for the Khandahar governor, Daud Ahmadi confirmed the death and said that Ahmed-jan had died on the spot. An investigation into the attack has begun, and local officials have blamed the Taliban.

Hundreds of men and women, including the Governor Asadullah Khaled were present at Ahmed-jan’s funeral on Monday evening, which took place in Khandahar’s main Shia mosque.

The killing has been strongly condemned by the Afghan President Hamid Karzai as well as aid and human rights organisations in Afghanistan.

Aleem Siddique, a spokesman for the United Nations Assistance Mission in Afghanistan (UNAMA), said that UNAMA was “appalled at the senseless murder” of a woman who was working to ensure a full and equal part in the future of Afghanistan for its women. He added, “We share the sentiment of the majority of Afghan people who are appalled at this killing.”

Abdul Quadar Noorzai, head of the Afghan Independent Human Rights Commission (AIHRC) for the Khandahar region told IRIN News that Ahmed-jan’s death will have a “serious impact on women’s activities in the south where women are already suffering from … the deteriorating security and conservative traditions,”.

Fariba Ahmedi, a woman MP from Khandahar who was present at Ahmed-jan’s funeral told the Associated Press, “The enemy of Afghanistan killed her, but they should know it will not derail women from the path we are on. We will continue on our way,”.

Sonja Bachmann, a U.N. political officer who knew Ahmed-jan well told the New York Times that Ahmed-jan “did a good job, she worked in a very low-key way and worked hard to raise awareness about women’s issues.”

Reuters and Associated Press received phone calls, claiming responsibility for the attacks on behalf of Mullah Sadullah, a regional Taliban commander, but no confirmation of the claim has been possible.

Another caller, who identified himself as Taliban commander Mullah Hayat Khan told Al Jazeera that Ahmed-jan was killed because she worked for the government.

The Taliban-led insurgency has stepped up attacks in recent months, killing hundreds of people this year.

Last week, 19 Afghans working for reconstruction projects in the region were killed after their bus was ambushed.The Governor of Paktia province, a close associate of President Karzai, was killed in a suicide bombing on September 10.

Attacks on schools have also been stepped up. According to the Afghan education ministry, there have been 158 attacks on schools this year, compared to 146 last year. The attacks on schools are believed to be due partly to the Taliban’s opposition to educating girls, as well as a way to undermine the Afghan government and it’s reconstruction efforts.

Twelve suspected militants and two Afghan police officers were reported killed on Monday in separate incidents which also left eight others and a U.S. soldier wounded.

“People are scared, of course,” Ahmad-jan’s co-worker Haidar said, “How can we feel secure when the head of our department is killed in front of her house?”

Evangelist Kent Hovind’s tax trial begins

Saturday, October 21, 2006

Evangelist Kent Hovind and his wife, Jo, are trying to convince a federal jury that their money from video and amusement park admission sales belong to God and cannot be taxed. The trial began at United States District Court for the Northern District of Florida on Tuesday October 18, 2006 after twelve jury members and two alternates were selected to decide on the 58 federal courts against Hovind and his wife. The trial was expected to take at least two weeks to complete with the prosecution hoping to rest its case Tuesday, but a defense attorney became ill and the Judge delayed the trial until October 30th.

Hovind is a Young Earth creationist who does many speaking engagements and debates. He also sells videos giving a pro-creationism perspective, which he receives income for. Hovind, who calls himself “Dr. Dino”, received a Ph.D in “Christian education” from the unaccredited correspondence school Patriot Bible University in 1991.

Prosecutor Michelle Heldmeyer said from 1999 to March 2004, the Hovinds took in more than $5 million. Heldmeyer charged Hovind on 12 counts for failing to pay about $470,000 in federal income, Social Security and Medicare taxes for his ministry employees between March 31, 2001, and Jan. 31, 2004. Counts 13 through 57 include Hovind’s wife for making 45 transactions in a little more than a year, sometimes taking out as much as $9,500 at a time. Banks are required to report cash withdrawals that exceed $10,000.

In count 58 against Kent includes filing a frivolous lawsuit against the IRS, demanding damages for criminal trespass, filing an injunction against an IRS agent, making threats against investigators and those cooperating with the investigation, and filing false complaints against the IRS for false arrest, excessive use of force and theft.

In July with his attorney, Public Defender Kafahni Nkrumah, Hovind stated that he did not recognize the government’s right to try him on tax-fraud charges.

This is not the first time Hovind has found himself in legal trouble. In 2002 he refused to get a $50.00 building permit for his Dinosaur Adventure Land, and after three years of legal battles the court ruled that he get a permit or the building would be razed. The park, which depicts dinosaurs as coexisting with humans in the last 6-4,000 years with the more recent “dinosaurs” being the Loch Ness monster, is reportedly open after Hovind paid for the permit and fines totaling $10,402.64.

More directly, M.C. Powe, an IRS officer who investigates people who have unpaid tax returns or unpaid tax liabilities, testified at Hovind’s current trial on October, 19, 2006 that she first attempted to collect taxes from the Hovinds in 1996. She noted Hovind tried several “bullying tactics” that included suing her at least three times. These resulted in each case being thrown out.

Assistant U.S. Attorney Benjamin Beard handled Hovind’s bankruptcy in 1996 testified on Wednesday that in 1996 after Hovind’s vehicles were seized by the IRS, he filed under the Chapter 13 “wage-earner plan,” available only to those who have a regular source of income. However, Hovind wrote that he had no form of income, that he rejected his Social Security number and that his employer was God, Beard testified.

In a 2005 affidavit, the Hovinds argue that Social Security is essentially a “Ponzi scheme.” The Hovinds referred to the United States Government as “the ‘bankrupt’ corporate government” and said they were renouncing their United States citizenship and Social Security numbers to become “a natural citizen of ‘America’ and a natural sojourner.”

Wikisource has original text related to this article:

On Thursday an employee of AmSouth Bank explained that the Currency Transaction Reports requires the bank to report any time a cash amount of $10,000 or more is withdrawn or deposited. This employee noted that various records demonstreated Jo Hovind had made transactions up to $15,000 at a time.

Also on Thursday Hovind’s former neighbor testified regarding Hovind’s purchasing of her Palafox Street home. On the stand she said Hovind paid her $30,000 in cash as part of the $155,000 sale.

In this week’s trial two of Hovind’s workers testified in federal court that they didn’t consider where they worked to be a church. In court Hovind maintains he does not have to pay the taxes because his employees were “volunteers,” “missionaries” or “ministers” and his business was a ministry.

However, Brian Popp, Hovind’s employee for at least eight years, said he considered himself a minister at the time of his employment, but said Hovind’s ministry isn’t a church. Popp also testified that Hovind knew about the bank’s requirement to report transactions over $10,000 and said it was “not safe to carry large sums of cash.”

Further, Popp said Hovind told his workers not to accept mail addressed to “KENT HOVIND” because Hovind told the workers the government created a corporation in his “all-caps name” and if the mail was accepted, Hovind claimed, it would be accepting the responsibilities associated with that corporation.

Diane P. Cooksey, served as a sales representative for the ministry from January 2003 to June 2005, and said Hovind expected to pay her own taxes. Cooksey said, “He explained what his belief was, right up front in the interview, that I would pay my own taxes.” As told’s worker, she received $10 an hour in a weekly paycheck, punched a time clock, was given 10 paid vacation days a year, and considered herself an employee, not a missionary as a few others called themselves.

The IRS raided Hovind’s Dinosaur Adventure Land in April 2004, after which Hovind required his employees to sign nondisclosure agreements. “I was uncomfortable signing it, I guess, because of not having a full understanding,” Cooksey said.

Rebekah Horton, vice president of the unaccredited Pensacola Christian College, took the stand on the second day of the trial and testified that “We know the Scriptures do not promote (tax evasion)”. “It’s against Scripture teaching.”

Horton was given a videotape in the mid 1990s from a woman who worked for Hovind. The video contained “another evangelist advocating tax evasion,” Horton explained. The woman who gave the tape to Horton claimed Hovind’s philosophy as “You were giving a gift with your work, and they were giving a gift back to you.”

Pensacola Christian College decided to disallow its students from working with Hovind’s Creation Science Evangelism and reported Hovind’s scheme to the IRS.

On Friday, attorney David Charles Gibbs testified that Hovind claimed he had no obligation to pay employee income taxes and explained with “a great deal of bravado” how he had “beat the tax system.” Gibbs is an attorney with the Gibbs Law Firm, also is affiliated with the Christian Law Association, a nonprofit organization founded by his father that offers free legal help to churches nationwide in a suburb of St. Petersburg, Florida. Gibbs attended the Marcus Pointe Baptist Church when Hovind was a guest speaker at the church on October 17, 2004. Hovind invited Gibbs and others to Hovind’s home for pizza and soda.

Gibbs testified they talked for many hours, and Hovind “tried to stress to me that he was like the pope and this was like the Vatican.” Also Gibbs explained Hovind also told him he preferred to deal in cash because “dealing with cash there is no way to trace it, so it wasn’t taxable.”

Wikisource has original text related to this article:

Later on Friday, Special IRS Agent Scott Schneider took up the remainder of the day and is expected to resume Monday. Schneider told the jury his investigation revealed that Hovind “hadn’t filed tax returns ever, to my knowledge.”

Hovind tried suing the IRS and Schneider several times to avoid providing information required by the IRS. Each filing was thrown out by the judges.

Schneider’s discussed documents seized during the 2004 raid of Hovind’s property. These documents, Schneider explained, indicated Hovind ran his ministry as a business with “meticulous” payroll documents and a time clock employees had to punch in and out.

In the raid cash was found “all over the place.” Ultimately, $42,000 in cash was seized along with half-dozen guns (including a SKS semiautomatic) at the Hovinds’ home.

The Pensacola News Journal noted that “in one memo, Jo Hovind informed her daughter, who works at the park, that her pay would be docked $10 for talking too long on the telephone when she should have been working.”

India records 14 millionth case of COVID-19 amid new surge in infections

Sunday, April 18, 2021

According to multiple reports, India recorded its 14 millionth case of COVID-19 and new infections of over 200 thousand on Thursday, causing multiple hospitals running on full capacity.

The 200739 new infections is twice what was seen during its last peak in September, rising after the superspreading events such as political rallies in local and state elections and religious events, official complacency and highly infectious new variants of the virus. According to Reuters, the government blamed wilful disregard of social distancing measures and face mask mandates. A Railway Protection Force officer told The Telegraph (Kolkata) “[t]he number of unmasked passengers was much more last month. The renewed surge in Covid numbers has triggered some caution but many are still without masks.”

According to CNBC, India overtook Brazil as the second-most infected country on April 12, though still behind the United States. The new strain has forced hospitals into drastic measures, including two or three patients sharing a bed at Lok Nayak Hospital and converting over a dozen hotels and banquet halls in New Delhi into COVID-19 treatment centres. The states Maharashtra, Madhya Pradesh and Gujarat among others have reported a shortage of oxygen; India Today reported on the Ahmedabad Medical Association pleading the state government for oxygen, writing to Gujarat chief minister Vijay Rupani “[i]f such conditions persist, the death toll will rise, violence against doctors will increase and doctors will be forced to shut down their hospitals due to lack of oxygen supply”.

Nationally, the government has shifted its focus from vaccine exporting to domestic production, entering 114 million jabs in peoples’ arms — the third-most, behind the US and China — and three million on Wednesday after recently approving for emergency use its third vaccine: Russia-developed Sputnik V. The government maintains there is not an oxygen shortage and that the primary issue with distributing inoculations to states is over-planning, not a supply shortage.

New Delhi announced stay-at-home orders and shuttered restaurants, malls, gyms and spas, with an exception for movie theatres at limited times and at limited capacity. Mumbai went further Wednesday, closing most industries, businesses and public places and restricting movement of people amidst a surge of labourers to the city. In addition to many cities and towns, the epicentral city of Maharashtra imposed a curfew, with only essential services open between 8pm and 7am. The Central Board of Secondary Education (CBSE) Class 10 exams have been cancelled, and Class 12 exams postponed.

There has also been 1038 new deaths, adding to the total death count of over 173 thousand and putting a strain on local cremation centres and burial grounds. It remains fourth in its death count after the US, Brazil and Mexico.

Medtronics Recall 6931 Lead}

Medtronics Recall 6931 Lead

by

John Humphrey

In October 2007, the patients and doctors were informed of the Medtronic recall of the Sprint Fidelis lead Model 6931. It was found that the Medtronic 6931 lead along with lead Models 6930, 6948 and 6949 were at risk of developing fractures in particular locations. As of October 2007, Medtronic was aware of at least 665 chronic fractures in returned Sprint Fidelis leads. The majority of these fractures (approximately 90%) have occurred in the anode or cathode conductors.

The Medtronic recall applies only to the leads and not implanted defibrillation or pacemaker devices. If a patient has one of the implanted leads their Patient ID card should contain one of the following four sets of numbers: 6930, 6931, 6948, 6949. These numbers may be part of a longer string of numbers on the ID card. Pacemakers help keep the heart from going too slowly compared to defibrillators which keep the heart from going too fast. The Medtronic Sprint Fidelis recall does not include Medtronic devices that are pacemakers. Patients who have Medtronic ICDs or CRT-Ds without Sprint Fidelis leads are also not affected by the Medtronic recall.

The 6931 Medtronic lead is a thin wire that connects an implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) directly to the heart. Defibrillators monitor a patients heart rhythms. They are surgically implanted for patients at high risk of sudden cardiac arrest. An electrical shock is transmitted or rapid pacing to restore normal rhythm when irregular heartbeats are detected. Defibrillators keep the heart from going too fast.

A total of 268,000 Sprint Fidelis leads were implanted in patients throughout the world, with 172,000 leads implanted in the United States. As of January 2007, approximately 5,387 Medtronic Sprint Fidelis Model 6931 leads had been implanted. Implantable cardioverter defibrillators (ICDs) and Cardiac Resynchronization Therapy-Defibrillators (CRT-Ds) are used to treat abnormal heart rhythms in patients which can cause the heart to suddenly stop. ICDs and CRT-Ds shock the heart back into normal rhythm by delivering a pulse of energy through an electronic wire (lead) that is connected to the heart.

Patients who have either received a Medtronic recall letter or have one of the lead recall Models listed on their patient ID card are urged to contact their doctors office with any questions about their leads. Doctors are encourage to analyze the risks versus benefits of either leaving the lead implanted along with careful monitoring or implanting a different lead model. Extraction of leads involves serious risks to the patient. Medtronics Independent Physician Quality Panel recommends that if one of the recalled leads (Medtronic lead 6931) requires removal, the surgery be performed by a doctor with extensive extraction experience.

It has been reported that doctors with limited extraction experience may significantly increase the risk of complications during extraction. Some of the reported complications of lead removal include: lead breakage and migration; avulsion of veins, myocardium of the tricuspid valve; tears of the myocardium or veins; hemothorax, tamponade, perforation, emergency cardiothoracic surgery, pulmonary emboli, and death. Lead extraction carries risks that need to be considered and discussed between the patient and their doctor. Published literature suggests major complications (death or surgical intervention) from lead extraction range from 1.4 7.3%.

Ginsburg becomes first United States Supreme Court justice to officiate a same-sex marriage

Sunday, September 1, 2013

Yesterday, Ruth Bader Ginsburg became the first United States Supreme Court justice to officiate a same-sex marriage. The ceremony took place in the District of Colombia, in the atrium of the John F. Kennedy Center for the Performing Arts. The center’s President Michael M. Kaiser married economist John Roberts before a group of around 200 guests.

Ginsburg is quoted by the Washington Post as saying of her officiating, “I think it will be one more statement that people who love each other and want to live together should be able to enjoy the blessings and the strife in the marriage relationship […] It won’t be long before there will be another”. The Supreme Court Justice is scheduled to officiate at another same-sex wedding ceremony later this month between David Hagedorn and director of communications and executive affairs for the National Weather Service Michael Widomski.

Justices occasionally perform marriages, often for those who have clerked for them. Ginsburg suggested same-sex couples hadn’t requested justices marry them before lest their involvement interfere if and when the issue came before the Supreme Court. Opposite-sex marriages officiated by members of the Supreme Court included Ginsburg officiating at her son’s wedding, and Justice Clarence Thomas officiating at one of Rush Limbaugh’s weddings.

Ginsburg was among the justices siding with the majority in two cases dealing with same-sex marriage that came before the Supreme Court this year.

Same-sex marriage is legal in thirteen US states and the District of Colombia. It is also legal in or in parts of seventeen other countries.

Apple unveils iPhone 4, iOS 4 at Worldwide Developers Conference 2010

Tuesday, June 8, 2010

Yesterday, at this year’s Apple Worldwide Developers Conference (WWDC), company CEO Steve Jobs unveiled iPhone 4, along with the new iOS 4 operating system for Apple mobile devices.

The announcement was long-awaited but not a very big surprise. In April, the technology blog Gizmodo obtained a prototype of the new phone and published details of it online. While introducing iPhone 4, at the annual conference, Jobs started by hinting at the incident, saying, “Stop me if you’ve already seen this.”

The new iPhone was praised by Jobs as “the biggest leap we’ve taken since the original iPhone.” It is only 9.3 millimetres (0.37 inches) thick, making it “the thinnest smartphone on the planet”, a 24 percent reduction from Apple’s previous model, the iPhone 3GS. Structure-wise, iPhone 4 has a new stainless steel frame, which acts as an antenna, supposedly boosting its signal reception abilities and possibly reducing the amount of dropped calls. It also has a new screen, dubbed a “retina display,” which displays images at 326 pixels per inch. During the keynote, Jobs demoed the device’s new internal gyroscope as well. Even though it now uses Apple’s faster A4 processor (first used in its iPad tablet), iPhone 4 has a claimed seven hours of 3G talk time, up two hours from the 3GS.

In addition to its design features, Jobs showed off iPhone 4’s new video calling abilities. This feature is called FaceTime, and connects with other iPhone 4s via Wi-Fi. The phone has two cameras: one on the front for video chats, and one on the back for taking pictures and other videos. The rear camera has a resolution of five megapixels, is capable of recording high-definition video, and has an LED flash.

The iPhone 4 will use Apple’s latest mobile operating system, iOS 4. Formerly “iPhone OS,” iOS 4 was first introduced by Apple in April, and includes multitasking capabilities. Jobs called the new software “the most advanced mobile operating system in the world.” iOS will support Apple’s new mobile advertising service, iAd, which goes live on July 1.

iPhone 4 will be available on June 24 in the United States, United Kingdom, France, Germany, and Japan. It comes in two colors—black and white—and two storage capacities. The 16GB version is priced at US$199 and the 32GB version at US$299. The iPhone 3GS’s price will be reduced to US$99, and the iPhone 3G will be discontinued. iOS will be available as a free software update to users of compatible older Apple devices (including the 3GS) on June 21. In the U.S., iPhone 4 will only be available on AT&T’s cellular network, despite calls for Apple to let the iPhone be used on other carriers, such as Verizon.

Competition-wise, the BlackBerry mobile device is still the most popular smartphone right now. Apple is also facing some serious competition from web giant Google’s Android operating system, as well as Palm’s webOS. Earlier this year, Android phones managed to outsell iPhones. iPhone users, however, account for over half of those surfing the Internet on a mobile browser in the U.S. Jobs also noted that over five billion iOS applications, commonly called “apps,” have been purchased from Apple’s App Store. The App Store currently has around 225,000 different apps for sale.

WHO warns of thousands of new Ebola cases

Wednesday, September 10, 2014

Liberia is expected to see thousands of new Ebola cases within the next three weeks, the World Health Organisation (WHO) said yesterday.

The current outbreak of the virus in West Africa is believed to have killed 2,100 people, including 79 health workers. As well as Liberia, Guinea, and Sierra Leone are at the centre of the outbreak, with Nigeria, and Senegal also effected.

As soon as a new Ebola treatment facility is opened, it immediately fills to overflowing with patients

Liberia is proving particularly vulnerable to the spread of the virus. Before the outbreak, the country had only one doctor for every 100,000 inhabitants, and a severe shortage of beds. The WHO stated that “as soon as a new Ebola treatment facility is opened, it immediately fills to overflowing with patients”.

The UK military have said they will build a 50 bed centre near Sierra Leone’s capital, with the US saying it would send a 25 bed field hospital. This falls short of the 1,000 beds an investigative team from WHO says is needed in Liberia’s capital, Monrovia, alone.

WHO says a three- to four-fold increase in the efforts of those combating the outbreak is needed.

The African Union also warned of the economic impact of the outbreak, urging a lifting of travel bans and border closures. WHO have previously warned that such travel restrictions increased the chance of food shortages. An agreement made yesterday is expected to lead to those restrictions imposed in the last few months being lifted.

Questions To Ask A Wedding Photographer

Submitted by: Teena Celis

Once you search for a wedding photographer, you should know precisely what queries to inquire so you will fully understand specifically what you will be getting after you hire one.

Denver wedding photography guru Matt Kelly said, Most wedding photographers provide you with more than just snapping the photographs at your wedding and then providing you images. It s essential that you ask several inquiries so that you know exactly what is available from a particular photography studio.

What questions should you ask?

It is less likely that you have ever had to hire a wedding photographer before so here are some questions you need to ask when you check out a photographer s studio.

Does the photographer are known for wedding photography? You want the reply to be yes . Be sure to check out his or her portfolio to make sure (s)he has a good amount of experience.

Is there more than one photographer available? If the answer is yes, browse through each photographer s portfolio to see whose style appeals to you. Be sure that the one you want is available on the time of your wedding.

How does the studio handle your prints? Do they do the editing and enhancing, color correction, and actual printing? If you ve seen the portfolios, ask who did the post-shooting work. You want only professionals for this part of the job.

[youtube]http://www.youtube.com/watch?v=IAU7RAtUk7o[/youtube]

Will the studio give you proofs so that you can pick the photos you want for your wedding album?

How long after the wedding before you receive the proofs?

If the wedding photographer has to travel out of town to your wedding, ask if there is an extra fee for that.

Does the photographer offer packages deals, and if so, what is included?

If shooting film, who keeps the negatives?

If using a digital camera, can you get a CD of the photos in additional to a wedding album? Is there an extra free for that?

How long will it take to get the final prints?

If you want some of your wedding photos in black and white, make sure to ask if the studio offers this option.

Ask for a list of recommendations. An experienced professional wedding photographer should have one. Before hiring anyone, make sure to follow up and call several of the references to see what their experience with the photographer was like.

Does the wedding photographer have liability insurance? You definitely want to hire one that does in cases where anyone at the wedding gets hurt, like stumbling over some of the photography equipment.

What are the backup plans if the photographer gets ill or has an emergency?

Will the photographer bring more than one camera to the wedding in case one malfunctions? Backup equipment is a must.

Ask if you can see a sample deal so that you will know what to expect, in general, when you hire your wedding photographer.

What will the photographer wear to the wedding? You want to be sure (s)he doesn t show up in jeans and a tee shirt if the wedding is formal or semi-formal.

Will (s)he be using an assistant? If so, is there an extra charge for that?

If you ask all these questions and more, Denver wedding photography expert Kelly said, an experienced wedding photographer will not mind. In fact, (s)he will be very happy to see you ve done your study as this will lead to open communication with no unpleasant surprises.

Don t be shy about asking all of your questions. You want to be sure to hire one of the best wedding photographer for your very special day.

Wikinews interviews British sensory biologist Dominic Clarke about floral electric fields and bees

Sunday, February 24, 2013

Last Thursday, British sensory biologist Dominic Clarke and other authors published research about detection of floral electric fields by bees in journal Science. The research involved studying bees’ reaction to flowers with different electric fields. The researches concluded that bees can choose flowers based on their electric fields, and remember them as they do with color and other characteristics of flowers.

This Friday Wikinews interviewed Dominic Clarke about the research.

((Wikinews)) What caused your initial interest in electric fields of flowers?

Dominic Clarke: There has been a considerable amount of speculation in the scientific literature since the 60s about the role of electric fields in pollination. It has been suggested that the electric field that arises between a charged bee and a grounded flower may be responsible for increasing the efficiency of pollen transfer between the two. We looked at this literature as sensory biologists and naturally formed the question ‘can bees sense these fields?’. Since we couldn’t find any answers to that question in the literature, we decided to find out for ourselves.

((WN)) How was the new phenomenon discovered?

DC: We use what’s called ‘differential conditioning’, where bees are trained to find a sucrose reward from an array of flowers, where only half of the flowers contain the reward. In our experiment, the flowers that were rewarded (with a sugary solution) were marked with a small electric field (about the same strength as around a flower in the wild). The ones that were not rewarded were not marked with fields. Since the electric field is the only thing that differs between the two flowers, we know that if the bees can learn to tell them apart, they can sense the electric field. Our bees were able to pick the rewarded flower 80% of the time when the electric field was present as a cue. When the electric field was switched off, they could only get it right half the time, which is the same as if they were just picking flowers at random.

((WN)) How many species of flowers and bees did you study during your research?

DC: We focus on one species of bee, the bumblebee Bombus terrestris. And we look mainly at Petunia flowers (P. integrifolia). These two species provide the bulk of our data, but we do consider other flowers like geraniums, daisies, clematis and foxglove, and other species of bee (particularly the honeybee Apis mellifera).

((WN)) Do you have diagrams, sketches, or drawings of electric field around a bee and a flower?

DC: I have attached a picture of a computer model of the electric field around a flower called “Flower Potentials and Fields”.

((WN)) Was it known that bees have a charge before?

DC: Yes, reports as early as the 70s have measured electrical charge on bees, but it was not known before whether or not they could sense such charges.

((WN)) What environment did you study the flowers and bees in? A laboratory? A garden? Natural environment?

DC: The behavioural tests were carried out in a laboratory because we needed to be able to precisely control the environment in which the bees were tested. Future work will be aimed at trying to get out into the bees’ natural environment and trying to figure out exactly what role(s) this sense plays in their lives.

((WN)) What equipment was used during the research? How did you measure the charge?

DC: Charge was measured using a device called a “Faraday Pail”. It is basically an electrically shielded metal cup, the voltage of which changes according to how much charge is inside it. We can measure this voltage when a bee flies in and so measure its charge. We did this with 51 individual bees.

((WN)) What were the roles of the people involved in the research? What activity was most time-consuming?

DC: It was very collaborative in all aspects of the research. I carried out the bulk of the experimental work and data analysis, but the process of designing the experiment, figuring out how to do the analysis, choosing which ideas to follow and which to put on the shelf etc., that is highly collaborative. Then of course comes the long period of writing, re-writing, re-re-writing, sending out to colleagues for feedback, re-re-re-writing, submission, peer-review, editing re-submission etc. which is also a collaboration between all the authors. A large part of doing science is talking as well; meeting, planning brainstorming. It feels to me like putting together the paper took the longest, but perhaps that’s just because it’s the most fresh in my mind.

((WN)) What do you see as possible directions for future research in this field? What do you think possible applications of the discovery can be?

DC: The two big questions now are “how do the bees do this?” and “why do they do this?”. The first is a case of pinning down the sensory mechanism used by the bees to detect the fields, and the second will involve a great deal of field-based experiments. We need to get out of the laboratory and understand the role this phenomenon plays in the lives of bees in the wild.

((WN)) Thank you for sharing your insight and details. Have a good time.
