quartz, chlorite, kaolinite, illite and various carbonate minerals) and intergranular porosity were also quantified through modal analysis. The longest axis of >100 grains were measured in each sample to produce grain size distribution plots, and the sorting parameter was calculated from the grain ...
Bacterial biomass found in soil ranges from 300 to 3000 kg/ ha. There are approximately 108to 109bacteria in a gram of soil, most of them (>99%) have not been or cannot be cultured in the laboratory. Common bacterial genera isolated from soil includeBacillus, Arthrobacter, Pseudomonas, Agro...
The Vajont hydropower station dam and reservoir was located at the foot of Mt. Toc in the Dolomite region of the Italian Alps. In October 1963, a large landslide of 260 million m3 of rock (equivalent of cube with a 650 meter side) filled the reservoir...
The deal: Honey contains trace amounts of vitamins and minerals, and because it has a lower glycemic index than sucrose, studies suggest it may not raise blood sugar as fast as other sweet products.14 It's generally better for the body to have a slow and steady rise in blood sugar after...
