The appellate courtâs task is to determine whether or not the law was applied correctly in the trial court. Appeals courts consist of three judges and do not use a jury. A court of appeals hears challenges to district court decisions from courts located within its circuit, as well as appeals from decisions of federal administrative agencies.
Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however. A few species of bacteria are able to use arsenic compounds as respiratory metabolites.he main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon.
Arsenic has many applications: Some compounds of arsenic are used as insecticides.In medicine, arsenic trioxide is used in the treatment of psoriasis. An isotope of arsenic (A â¦ s-74) is used as a tracer in some diagnostic imaging.Most metallic arsenic is used in forming alloys of lead and copper. (Unalloyed lead is too soft for many purposes).Arsenic atoms are used to create n-type regions in silicon, when fabricating transistors and integrated circuits.
