Either the single mechanism or a combination of these well regulatory mechanisms helps the bacterial cell to retain essential quantity of zinc and to avoid the toxic concentration of zinc to build up inside the cell.
The effective atomic number and effective electron density are the basic essential quantities used for determining the penetration of X-ray and gamma photons in matter.
More efficient storage methods are essential if large quantities of yams are to be collected at regional centres.
In the organic farming system plant production mostly depends on the decomposition of soil organic matter through the activity of the microbial biomass, which is able to provide significant quantities of essential nutrients for plant growth.
These four classes of food wastes were considered for evaluation in the present study as they contribute particularly large quantities of essential elements.
Thus, the organic fertilizer produced by the new process (Fig. 1) can be widely used in agriculture to supply sufficient organic matter for the carbon-craving soil and balanced quantities of essential nutrients for plants.
This enhanced growth was also confirmed from the quantities of essential elements i.e. carbon, hydrogen and nitrogen.
Only 27% of hospitals and about 40% of other health facilities report receiving the requested quantities of essential drugs ordered through the National Medical Store (NMS) [ 13].
Only 27% of hospitals and about 40% of other facilities reported receiving the quantities of essential drugs they ordered through the NMS [ 13].
Because Se is also an essential micronutrient, small additional quantities of this element may have been transferred to eggs as an active constituent of important seleno-proteins.
