IN a previous paper [Morris and Morris, 1930] it was shown that drying of blood at 1050 for a period of 4 hours led to, a diminution in the chlorine content and it was suggested that the chlorine lost by drying was probably contained in a volatile organic compound. Sunderman and Williams [1931] published figures indicating that while a loss of chlorine occurred on drying blood and tissues it co...
Autopsy specimens from human victims or experimental animals that die due to acute chlorine gas exposure present features of cardiovascular pathology. We demonstrate acute chlorine inhalation-induced reduction in heart rate and oxygen saturation in rats. Chlorine inhalation elevated chlorine reactants, such as chlorotyrosine and chloramine, in blood plasma. Using heart tissue and primary cardio...
Society’s preference for bottled water mainly comes from a dislike of the mildly pungent taste and odor of tap water. Such odor and taste may be caused by chlorine residual (in the form of free chlorine or chloramines), which is maintained in a water distribution system to prevent regrowth of microorganisms and is thus present in tap water. To encourage individuals who drink bottled water to sh...
A method has been developed for the synthesis of granular polymeric materials with immobilized N-chloro-sulfonamide groups. Commercially available resin polymers widely applied preparation ion exchangers have used as polymer carriers. The elaborated technological conditions make it possible to modify these resins a high conversion degree, without deteriorating strength characteristics, and poss...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Exposure of Escherichia coli O157:H7 to chlorine before heat treatment results in increased production of heat shock proteins. Current heating regimens for pasteurizing apple cider do not account for chlorine exposure in the wash water. This research determined the effect of sublethal chlorine treatment on thermal inactivation of E. coli O157:H7. D58-values were calculated for stationary-phase ...
Chlorine is a common agent found worldwide in industrial and household applications. This element is found everywhere and anywhere around the globe. Because of its ubiquitous nature in the world, chlorine-injured patients may be expected at all medical facilities, from large-urban to small-community to austere-tent facilities. Chlorine has been used as a chemical weapon since 1915 and has been ...
A test system for water distribution was used to evaluate the stability and effectiveness of three residual disinfectants--free chlorine, combined chlorine, and chlorine dioxide--when challenged with a sewage contaminant. The test distribution system consisted of the street main and internal plumbing for two barracks at Fort George G. Meade, MD. To the existing pipe network, 152 m (500 ft) of 1...
