The water turbine rotation is delivered to a generator, which generates electricity. The quantity of electricity that can be produced at a hydroelectric plant relies upon two variables. These variables are (1) the vertical distance that the water falls, called the "head",...
When seeds are primed with nanoparticles, water enters the seed through the seed coat by fastening the germination rate with a better establishment [163]. Servin and White [164] explained that nanoparticles could cause phytotoxicity through the release of toxic ions, and an excess of reactive ...

We outline the processes by which plant carbon enters the soil and critically evaluate isotopic methods to quantify them. Then, we consider the balancing CO2 flux from soil and detail the importance of partitioning the sources of this flux into those from recent p 展开 ...
That is, the ratio PES/EU does not provide any useful information about either the exploitation of the PES into EC (e.g. the efficiency of the power plant generating electricity) or the conversion of the EC into EU (e.g. the efficiency of the refrigerator in using electricity). On the...
