Jolt to Quit Smoking

... In addition, the hemoglobin in smokers' blood has carbon monoxide attached to it and can't carry as much oxygen. Both smokers and former smokers have more atherosclerosis in the blood vessels of the heart that lower the oxygen level. Any of these factors can result in an imbalance of oxygen supply compar...

Heparin Based Nanoscale Materials Developed For Dialysis Treatment

The Multi-Faceted Chemical Benzene

...radical hydroxyl reacts with the benzoic acid, the carbon dioxide is removed and what is left is benzene. But no action was taken by the FDA to impose penalties or regulations on the soft drink industry. One reason for the rather lax way in which the problem was handled was the fact that the risks posed ...

Fuel demand to be met by Bio-diesel

...uilt oxygen, which helps to reduce the emission of carbon dioxide and other polluting particles. "In a nutshell, bio-diesel is eco-friendly," Kumar told IANS. "We have already developed small units with capacities of five, 10 and 50 litres and one 1,000-litre unit will be ready within five to six months...

Liquid Respiration Respirator For Premature Babies

...the very last alveoli. Here oxygen is released and carbon dioxide taken up in the same way as on the respiration surface. Then the respirator extracts part of the perfluorocarbon from the lungs and introduces the next oxygenated dose. The same machine carries out the removal of CO2 from the perfluorocarbon ...
