The absence of vision in half of a visual field is described as hemianopsia. The visual field of each eye can be divided in two vertically, with the outer half being described as temporal, and the inner half being described as nasal.
The Dahlgren Decon solution will neutralize a wide range of substances, from toxic industrial chemicals and materials to chemical warfare and biological agents. The new decontamination solution has a moderate pH and does not generate toxic-byproducts.
The fluid polymer is then forced through the spinneret, where the polymer cools to a rubbery state, and then a solidified state. There are different types of spinning. Dry spinning is also used for fiber-forming substances in solution. However, instead of precipitating the polymer by dilution or chemical reaction, solidification is achieved by evaporating the solvent in a stream of air or inert gas.
