    Conservation Officers: A Force Multiplier for Homeland Security

    Today's law enforcement officers—both conservation and police—find themselves adapting to an emerging and dynamic threat environment. Policies and practices aimed at the prevention of threats have focused primarily on federal, state, and local police agencies. At a time when terrorists, extremists, and activists have begun to widen their array of attack methods, collaboration across all sectors of law enforcement becomes essential. More specifically, an increased vulnerability to biological threats has not been met by steps to prevent or mitigate these threats. Conservation officers have a unique and integral role to enhance homeland security efforts given their day-to-day operations and interactions with the community, especially rural America. This article will discuss the role of conservation officers as it relates to homeland security—a significant conceptual component to research and practice that has largely been ignored by both academics and professionals. The integration of conservation officers into the proactive information sharing environment will be discussed to strengthen a culture of information sharing as it pertains to an “all-threats, all-hazards” philosophy and to enhance national security awareness. Moreover, this article will challenge the traditional range of threats associated with biological terrorism by providing an illustrative case study

    Diesters of poly (ethylene glycol) with various a amino acid hydrochlorides were synthesized using dicyclohexyl carbodiimide as coupling agent. The use of hydrochloride as amino protecting group in dicyclohexyl carbodiimide mediated condensation reactions of amino acids was demonstrated for the first time

    Background:Cerebrovascular accidents (CVA) or stroke ranks first in frequency and important among all the neurological diseases of adult life. 50% of neurological disorders in a hospital are of this type. It is the third leading cause of death throughout the world. The prolonged morbidity and extended hospitalization required by these patients makes the disease one of the most devastating in medicine. The purpose of the present study was to document the presence or absence of hemorrhage or infarct, to determine the size, location of infarct, reasonably assessing the territory to blood vessels involved and to detect the incidence of negative cases of clinically suspected stroke.Methods:100 cases admitted to KIMS, Hubli and those referred to the NMR scan centre, Hubli with the clinical diagnosis of acute stroke were taken up for the study. The study was done from May 2010 to April 2012.Results:Out of 100 patients clinically suspected of CVA, submitted for CT scan study of the brain, 69 patients had infarcts, 21 patients had hemorrhage, 8 patients had CVT, 1 patient had SAH and 1 patient had normal scans. Infarcts (69%) formed the major group of the CVA cases involving most commonly the LMCA territory in 10 (14.49%) patients. Hemorrhage (21%) formed the second major group of CVA cases involving most commonly the RMCA territory 9 (42.85%) patients.Conclusions:CT scanning is a gold standard technique for the diagnosis and management of stroke and can be ideally done in all cases.The role of computed tomography in the evaluation of                cerebrovascular accident

    Novel low antimicrobial toxicity imidazolium ionic liquids: design, synthesis and their applications in organic synthesis

    This thesis is focused on the synthesis and application of ionic liquids in organic synthesis. A library of novel imidazolium ionic liquids was designed and synthesised in efforts to find molecules which had reduced anti-microbial toxicity and increased aerobic biodegradation. Synthesis of novel ionic liquids has been carried with efficient and easy methods to achieve atom economy, reduced number of steps and high yields. Ionic liquids synthesized in the lab have been tested either as a catalyst in acetalization reactions, or as a solvent in Carbonyl-Ene reactions. These studies have given excellent results and clearly demonstrated the potential and applicability of ionic liquids in organic synthesis. Working with our collaborators, anti-microbial toxicity and biodegradation of these ionic liquids has been studied. Preliminary studies of the toxicity of all ionic liquids were performed against a panel of 12 fungi and 8 bacterial strains. Antifungal and antibacterial toxicity studies demonstrated that most of these ionic liquids did not inhibit the growth of any organism screened at concentrations of 2.0 mM. Biodegradation studies of the novel of novel ionic liquids have also been performed and have given valuable information on the next step in rational design towards novel readily biodegradable ionic liquids
