Principle of silage making At harvest, plant cells do not immediately “die”; they continue to respire as long as they remain ade-quately hydrated and oxygen is available. The oxygen is necessary for the physiological process of respi-ration, which provides energy for functioning cells. In this process, carbohydrates (plant sugars) are con-sumed

The gold in the veins can be in many different forms like nuggets or sheets, or in gold compounds. In recovering gold from vein ore, the ore is first crushed in rod or ball mills. In this process the ore is crushed to a powdery substance from which the gold can be extracted by gravity separation.
Gold can be concentrated and recovered by applying different gold refining process methods and the final product has variable quality. In this way, it is necessary to have a better marketable product so that the incomes can be improved.
Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.

covered by photoresist. This process is called doping, because impurities are introduced into the silicon. This alters the conductive properties of the silicon (making it conductive or insulating, depending on the type of ion used) in selected locations. Here we show the creation of wells, which are regions within which transistors will be formed.
