To boldly go where public health hasn't gone before

Rollins School of Public Health researchers will soon take their research into orbit, partnering with the National Aeronautics and Space Administration (NASA) in a new satellite mission to study air pollution.

NASA chose Rollins as a joint recipient of its $100 million award � $2.3 million of which will come to Rollins � to study the effects of air pollution on the population through a satellite mission, according to Yang Liu, associate professor of environmental health. He noted that this is the first time a NASA space mission has incorporated a public health component.

"We're the scientific guinea pig," Liu said.

The Rollins research group, led by Liu, co-created the project idea with NASA's Jet Propulsion Laboratory (JPL). The mission will construct and use a Multi-Angle Imager for Aerosols (MAIA) device to record airborne particulate matter, which will collect data on the effects of pollution on public health from at least 10 locations with major metropolitan areas.

Once constructed by JPL, the MAIA device will be mounted on a compatible Earth-orbiting satellite. "Even though it's a small mission, it's actually the first ever in which we get to work with NASA engineers to build public health into the DNA of this instrument," Liu said.

The Rollins team will analyze the data to make predictions about public health issues such as birth outcomes and cardiovascular disease. The team will also serve as the public health liaison between JPL and other institutions in the complete research group. Recruited by Liu, the complete group has teams at University of California, Los Angeles, Harvard University, University of British Columbia, and University of Dalhousie.

Because the device will orbit via satellite, it will provide a more holistic view of air pollution data than the commonly used ground monitors.

"It's very difficult to cross to a completely different scientific community and convince them that this mission is not only worthwhile but also feasible," Liu said. "Hopefully, Emory will make a mark in NASA history."

GATHERING INFORMATION KYA HAI gathering information iska nam se h pata chalta hai ki ye hame information dene ke kam me aata hai ab aapke dimag me ye sawal aaraha hoga ki ye kin kin chijo ka information hame deta hai to aapko shortcut me batao to ye hamari target ka detail deta hai jaise ki hame kisi website ka detail chahiye to ham isse apne target matlab oss website ka pura detail isse h nikal sakte hai . Information Gathering ek parnetration testing ka sabse pahla phase hai agar Information Gathering aapke target ke bare me puri tarah se detail nahi dikha raha hai to iska yahi matlab hai ki aap jis website ko target bana rahe ho wo highlly protected hai jisko Information Gathering Access nahi kar pa raha hai but ab aisa nhi hai kyoki ab Information Gathering ki jarurat bas hame procces ko pura karne ke liye karte hai kyoki ab kali linux hamare kam ko bahut h eassy bana diya hai kali linux ki madad se hamara 50% kam aasan ho jata hai bas hame command ki achi jankari honi chahiy...

Any nearly pure Aloe vera  liquid product, whether called Gel, Juice or Whole Leaf Extract, comprises the fluid  obtained by breaking up the structure of the Aloe leaf and separating off the solid  residues to leave a more or less clear solution. The Egyptians called Aloe the �Plant of Immortality� because it can live and even bloom   without soil. Aloe has been used medicinally since at least the first century C.E. and  continues to be used extensively worldwide. In Egypt, aloe was called �the plant of  immortality� and was given as an offering at the funerals ...
