A Gridded Data Set of Temperature and Salinity Produced by Using Objective Analysis Method for China Offshore Waters and Adjacent Sea Are. For example, one of the most popular data sets on multidisciplinary repository Dryad is about wood density around the world. MegaFace's creators say it's the largest publicly available facial-recognition dataset out there. Create a data set that lists work items, including the STATE_NAME column. Our study will use a large corporate dataset from a major medical company to examine how technology extends our working hours and thus interferes with necessary cognitive recovery, resulting in huge health care costs and turnover costs for employers.

Unified Named Entity Recognition as Word-Word Relation Classification Cystic fibrosis affects 30,000 children and young adults in the US alone Cystic fibrosis affects 30,000 children and young adults in the US alone Inhaling the mists of salt water can reduce the pus and infection that fills the airways of cystic fibrosis sufferers, although side effects include a nasty coughing fit and a harsh taste. That's the conclusion of two studies published in this week's issue of The New England Journal of Medicine. They found that inhaling a mist with a salt content of 7 or 9% improved lung function and, in some cases, produced less absenteeism from school or work. Cystic fibrosis, a progressive and frequently fatal genetic disease that affects about 30,000 young adults and children in the US alone, is marked by a thickening of the mucus which makes it harder to clear the lungs of debris and bacteria. The salt water solution "really opens up a new avenue for approaching patients with cystic fibrosis and how to treat them," says Dr Gail Weinmann, of the US National Heart, Lung, and Blood Institute, which sponsored one of the studies. Mark Elkins of the Royal Prince Alfred Hospital in Sydney, Australia and colleagues authored one of the new published studies. The team found that the 83 volunteers who regularly inhaled a 7% mist of salty water had fewer breathing problems and less absenteeism from school or work than those who inhaled a solution with a salt content of under 1%. "Adding salt [and water] to the airway surfaces of patients with cystic fibrosis is beneficial" for both children and adults, they conclude. All of the patients first inhaled a chemical to try to open their lung passages as much as possible. In the second study, US-based Assistant Profsesor Scott Donaldson of the University of North Carolina at Chapel Hill and his colleagues found that a 7% salt mist "produced a sustained acceleration of mucus clearance and improved lung function" because it helped hydrate the lungs. In an accompanying editorial, Dr Felix Ratjen of the Hospital for Sick Children in Toronto, Canada, cited several unpleasant side effects of the salt mist treatment including a bad taste, coughing fits and the lengthy 30 minutes it can take to administer. He added that in the study by Elkins and team, patients may not have received the best long-term antibiotic treatment. That would make the inhaled salt water mist appear more effective than it would have been if people were getting a better drug, says Ratjen. Weinmann says limitations inherent to the treatment mean a salt water mist "may be just a first step" in treating cystic fibrosis. Scientists have rescued a mouse immune system that was overwhelmed by a systemic blood infection. But will this work in humans? Scientists have discovered how infections that invade the whole body, like malaria, disable the immune system and prevent it from detecting and fighting other microorganisms. The Australian and German researchers say the discovery may help scientists to develop vaccines that restore immunity in people with systemic or 'whole body' infections. They publish their research today online in the journal Nature Immunology. The immune response is alerted when specialised sentries of the immune system, dendritic cells, detect a virus or bacteria. They alert the immune system by capturing infected cells and displaying fragments or antigens of the pathogen on their surface in a process called cross-presentation. Lead researcher Dr Jose Villadangos, an immunologist from the Walter and Eliza Institute of Medical Research in Melbourne, says systemic infections such as malaria or sepsis, a bacterial infection of the blood, overstimulate dendritic cells. This results in the immune system's critical alarm system shutting down. "This doesn't occur in local infections because only a few dendritic cells are involved," Villadangos says. "But in the case of malaria infections and sepsis, dendritic cells throughout the body are concentrated on alerting the immune system, which prevents them from detecting and responding to any new infections." A new type of vaccine? Villadangos and colleagues managed to restore immunity in mice with an immune system compromised by sepsis. They injected them with a live vaccine made of dendritic cells that had been exposed to a secondary virus in the laboratory, and subsequently displayed antigens of that virus. Villadangos says the findings show the missing link in the immunosupressed animal is the capacity of the dendritic cells to display the antigens of new viruses. "We should be able to take dendritic cells from a patient with sepsis or malaria and expose them to antigens of the virus of a secondary infection and inject them back into the patient. "This strategy is already being used in the development of anti-cancer vaccines. We are yet to find out if will work against secondary infections in humans with a systemic infection," Villadangos says. Scientists will analyse the contents of this capsule for clues about how the solar system began A seven-year quest to return to Earth pristine samples from the solar system's formation ended in triumph in a dark and wet Utah desert at the weekend. "It's hard to describe what it feels like to be at this point of the mission," University of Washington researcher and lead scientist of the Stardust mission Professor Don Brownlee said shortly after the probe's touchdown at 10:10 UTC (21:10 AEDT) on Sunday. "We travelled almost 3 billion miles in space. We visited a comet, grabbed a piece of it and it landed here this morning," Brownlee said. "It's an incredible thrill." Stardust released its precious cargo during a high-speed flyby of Earth, sending the tyre-sized canister soaring through space at a blazing speed of about 46,000 kilometres per hour when it smashed into the planet's atmosphere. This makes it the fastest human-made object, topping the record set in May 1969 by the returning Apollo 10 command module. As its heat-shield fried away, a comet-like plume formed in its wake, looking like a torch that was visible in parts of the western US. "We weren't quite sure how bright it was going to be and some people didn't think we would see anything," says Brownlee, who slipped outside the Utah base with some of his team members to try to spot the capsule's streak across the sky. After scanning the sky for several minutes, Brownlee finally found an object that he said looked like Mars, but was clearly not where Mars was at the time. "It was twinkling a little bit, getting a little brighter, and moving. I thought, maybe that's a helicopter. But it kept getting brighter and brighter and brighter," he says. The object was reddish in colour and trailed a bright, glowing plume behind it, Brownlee says. "It's ironic, you have a comet mission that ends producing a comet." Collecting spacedust During its time in space, Stardust passed by Comet Wild-2 (Vilt-2) and extended a gel-filled collecting device to trap some particles to take back to Earth. It also collected bits of interstellar dust. Scientists believe comets contain unaltered material that was used to form the solar system. "We did this miss
