The Warfare agents possess different characteristics and belong to various classes of compounds with pronounced physicochemical, physiological and chemical properties. They are classified in many ways based on their volatility, as persistent or non-persistent agents. The more volatile an agent, the quicker it evaporates and disperses. The volatile agents like chlorine, phosgene and hydrogen cyanide are non-persistent agents whereas the less volatile agents like sulfur mustard and Vx are persistent agents, based on their chemical structure, they are classified as organophosphorus , organosulfur and organofluorine compounds and arsenicals.
Impact Factor of a scholarly journal is calculated by measuring the average number of citations to recent articles published in the particular journal. Impact factor gives the importance of a Specific journal with respect to other journals. Impact factor is calculated based on the average number of citations a paper published in a particular journal receives in a span of two years. Impact factor for the new journals will be considered after two years. Impact factor of a particular journal will give complete picture of the quality and standards of the journals. For example, if a journal has an impact factor of 5 in 2012, then its papers published in 2010 and 2011 received 5 citations each on average in 2012. The 2012 impact factor of a journal would be calculated as follows:
X = Number citation for the articles published during 2010 and 2011.
Y = the total number of articles published by that journal in 2010 and 2011
2012 impact factor = X/Y.
