|Using agricultural residues for industrial purposes is a much more environmentally friendly practice than many residue disposal methods currently in use Agricultural residues are an excellent alternative to using virgin wood fiber for many reasons. Aside from their abundance and renewability, using agricultural residues will benefit farmers, industry and human health and the environment. Wheat straw, for example, is being grown at yields of between 1-3 tons per acre. This income is a boon to farmers. In fact, one manufacturer, Agriboard Industries, claims that local farmers stand to make more from selling the wheat straw than from selling the actual crop. Until recently, many farmers disposed of agricultural wastes by burning or land filling them. The manufacturers currently using wheat straw as an industrial feedstock pay up to $45 per ton.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
