High school gossip has evolved over the years from a few nasty words scrawled in magic marker on a bathroom wall to anonymous apps that smartphone-savvy students can check instantly 萬能的七唯國度.

"Inadvertently, the people who developed these apps have created a digital bathroom stall for thousands of people to see," John Dodig, principal of Staples High School in Westport, Conn., told ABCNews.com live that fancy.

The problem of hurtful words being transmitted over anonymous apps at Staples became such an issue that Dodig said his school received a "geo fence" from Yik Yak, a popular anonymous bulletin board app. The geo fence works by taking the school's latitude and longitude and blocking the app on campus cherish reanson tonight.

The periodic table of the elements is to get crowded towards its heaviest members. Evidence for the artificial creation of element 117 has recently been obtained at the GSI Helmholtz Centre for Heavy Ion Research, an accelerator laboratory located in Darm-stadt, Germany. The experiment was performed by an international team of chemists and physicists headed by Prof. Christoph Düllmann, who holds positions at GSI, Johannes Gutenberg University Mainz (JGU), and the Helmholtz Institute Mainz (HIM). The team included 72 scientists and engineers from 16 institutions in Australia, Finland, Germany, India, Japan, Norway, Poland, Sweden, Switzerland, the United Kingdom, and the United States. Elements beyond atomic number 104 are referred to as superheavy elements. The most long-lived ones are expected to be situated on a so-called 'island of stability', where nuclei with extremely long half-lives should be found. Although superheavy elements have not been found in nature, they can be produced by accelerating beams of nuclei and shooting them at the heaviest possible target nuclei. Fusion of two nuclei -- a very rare event -- occasionally produces a superheavy element. Those currently accessible generally only exist for a short time. Initial reports about the discovery of an element with atomic number 117 were released in 2010 from a Russia-U.S. collaboration working at the Joint Institute for Nuclear Research in Dubna, Russia no reason back sunshine.

In a powerful example of international collaboration, this new measurement required close coordination between the accelerator and detection capabilities at GSI in Germany and the unique actinide isotope production and separation facilities at Oak Ridge National Laboratory (ORNL) in the U.S. The special berkelium target material, essential for the synthesis of element 117, was produced over an 18-month-long campaign. This required intense neutron irradiation at ORNL's High Flux Isotope Reactor, followed by chemical separation and purification at ORNL's Radiochemical Engineering Development Center. Approximately 13 milligrams of the highly-purified isotope Bk-249, which itself decays with a half-life of only 330 days, were then shipped to Mainz University. There, the facilities and expertise are available to transform the exotic radioisotope into a target, able to withstand the high-power calcium-ion beams from the GSI accelerator. Atoms of element 117 were separated from huge numbers of other nuclear reaction products in the TransActinide Separator and Chemistry Apparatus (TASCA) and were identified through their radioactive decay. These measured chains of alpha-decays produced isotopes of lighter elements with atomic numbers 115 to 103, whose registration added to the proof for the observation of element 117 Hong Kong news and information 香港新聞資訊.

In the decay chains, both a previously unknown alpha-decay pathway in Db-270 (dubnium -- element 105) and the new isotope Lr-266 (lawrencium -- element 103) were identified. With half-lives of about one hour and about 11 hours, respectively, they are among the longest-lived superheavy isotopes known to date. As unwanted background events are present in all superheavy element experiments, the longer-lived an isotope is, the harder is its reliable identification. The present experiment, for which TASCA was significantly upgraded to better separate unwanted background products and thus to allow more sensitive identification of superheavy nuclei, proved that their reliable identification is now possible lin beauty pinkheaven in sky.

"This is of paramount importance as even longer-lived isotopes are predicted to exist in a region of enhanced nuclear stability," explains Christoph Düllmann.

Prof. Horst Stöcker, Scientific Director of GSI, adds: "The successful experiments on element 117 are an important step on the path to the production and detection of ele-ments situated on the 'island of stability' of superheavy elements cry me a sea 寂しさの干潟寒い."

A penny-pinching farmer didn't want his hired hand to stop working. One morning, he told the farmhand, "It's such a nuisance to come in from the field, wash up for lunch and take time to eat. Why don't we save time and eat lunch now?"交友

Al Qaeda leader Osama bin Laden urged European countries to end their military cooperation with US forces in Afghanistan, in an audio tape aired by Al Jazeera television on Thursday.银河的礼物

He said American power was waning and it would be wise for the Europeans to quickly end their role in Afghanistan, where many European countries contribute to the 50,000-strong NATO and US-led coalition forces. "With the grace of God ... the American tide is receding and they would eventually return to their home across the Atlantic ... It is in your interest to force the hand of your politicians (away from) the White House," said bin Laden. In Washington, a US counterterrorism official said the voice on the audio tape appeared to be bin Laden's. It was not immediately clear when the new message was recorded.Table For Six

The United States led the invasion of Afghanistan to depose its Taliban rulers in late 2001, after they refused to hand over bin Laden and other al Qaeda leaders following the September 11 attacks on the United States. Bin Laden did not make any threat in the portions of the recording aired by Jazeera. The full tape is yet to be released by an Islamist Web site.parrot wig ancestry

In the portions aired by Jazeera, bin Laden said the Taliban had no knowledge of plans for the 2001 attacks.GREEN FLOWER LAUGH

"I am the one responsible... The Afghan people and government knew nothing whatsoever about these events," he said, adding that the United States had not provided any evidence of Taliban involvement to justify its invasion. "Europe marched behind it with no choice but to be a lackey," bin Laden said.paradise world

"I'm addressing you (Europeans) and not your politicians ... (who) like to be in the shadow of the White House as many world leaders," he said, naming current and former leaders of Britain, France, Spain and Italy, including French President Nicolas Sarkozy and British Prime Minister Gordon Brown. The United States has been urging its NATO allies to send more troops to Afghanistan, but European nations remain reluctant to commit further reinforcements.Shine Like Diamond

Before becoming health and human services secretary in 2009, Ms Sebelius was governor of Kansas. Ms Burwell's nomination to lead the Department of Health and Human Services requires Senate confirmation. She held several positions in the White House and treasury department under President Bill Clinton, and also led global development at the Bill and Melinda Gates Foundation. "I look forward to carrying on the important work of ensuring that children, families and seniors have the building blocks of healthy and productive lives," she said.交友
