Standard treatment of poisoning by organophosphorus anticholinesterases uses atropine to reduce the muscarinic effects of acetylcholine accumulation and oximes to reactivate acetylcholinesterase (the effectiveness of which depends on the specific anticholinesterase), but does not directly address the nicotinic effects of poisoning. Bispyridinium molecules which act as noncompetitive antagonists...

Chemistry by computer provides access to microsystem information not readily achieved by other means. Simple computational analysis of saturated triglyceride polymorphism by molecular mechanics within constraints provided by X -ray data show that polymethylene interactions determine hydrocarbon crystal properties when they account for more than 60 percent of the total molecular interaction ener...

We have investigated the effects of film composition and thickness on the rate of pH-induced response of a copolymer film containing predominately polymethylene with randomly distributed carboxylic acid side groups (denoted as PM-CO2H). These responsive films are prepared directly onto a gold electrode surface by surface-catalyzed polymerization and subsequent hydrolysis. We measured electroche...

releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...

lish Midlands, is famous for its association with Robin Hood, whose statue stands in the shadow of the castle wall. The Sheriff of Nottingham still has a special role in the city government although happily no longer strikes terror into the hearts of the good citizens. Recently a new attraction, a windmill, has appeared on the Nottingham skyline (see figure 1). The sails turn on windy days and ...

urban green spaces are one of the most important services in modern cities and form a set of urban sustainable development factors which receive considerable attention from urban planners. this paper explains how land use can be optimally allocated to urban public green spaces. in this study, some of the factors influencing urban green spaces in a period from 1373 to 1384 were studied. moreover...
