Growing evidence suggests that most particles formed during natural gas combustion are in the nanoscale. There exists the potential for adverse effects due to exposure to these unintentionally produced particles. This exposure may be occupational, in the home, or in ambient air. Currently, measurement...

Hydrogen peroxide inhalation is another effective treatment for pneumonia. The process oxidizes the lungs, which functions to eliminate infection and other pathogens. The additional oxygen in the system also supports lung function. Pneumonia can range from mild to life-threatening. However, as you will...
“The oil and gas industry has left thousands of orphaned wells from previous fossil fuel booms. Taxpayers may wind up on the hook for the considerable expense of plugging and reclaiming orphaned wells – Cabot Oil & Gas claims to have spent $730,000 per well to cap three shale gas wells ...
Extracts from these stems have been shown to contain enormous amount of phytochemicals which have antioxidants, haematinic effect, antimicrobial effects etc, which significantly builds the blood cells, boosts the immune systems, cleanses the circulatory system, helps to balance the entire body’s syste...
The major exposure of the population to natural radiation arises from inhalation of the short-lived radioactive progeny of the radioactive noble gas radon-222, which in turn is a sixth-generation radioactive decay product of natural uranium. The amount of radon-222 present in the air depends ...
Then samples were weighed and hermetically sealed to prevent the escape of radon gas. Samples were kept for 45 days to obtain a secular balance between 226Ra (238U daughter) and 232Th daughter before the measurements20. Activity determination The activity of each sample was counted for a period...
The concentrations of NO, NO2 and NOx for direct injection (DI) combustion were analysed on the basis of experimental data by using a rapid compression machine fuelled with compressed natural gas (CNG) and gasoline. The analysis showed that the maximum values of NO and NO2 for stratified comb...

stem cells therein. Amniotic stem cell preparations contain many of the growth factors and signaling proteins produced by MSC’s (which is why they are somewhat clinically effective), but their diminished effects are not sustained since there are no live stem cells present to continue producing ...
