Source attribution of black carbon in Arctic snow.
Snow samples obtained at 36 sites in Alaska, Canada, Greenland, Russia, and the Arctic Ocean in early 2007 were analyzed for light-absorbing aerosol concentration together with a suite of associated chemical species. The light absorption data, interpreted as black carbon concentrations, and other chemical data were input into the EPA PMF 1.1 receptor model to explore the sources for black carbo...
متن کاملYeast-generated CO2 as a convenient source of carbon dioxide for adult mosquito sampling.
A new, convenient method was developed to supply CO2 for mosquito sampling by using yeast, which converts sugar into CO2 and ethyl alcohol. The system could, at average, generate 32.4 ml/min of CO2 for at least 27 h. The total weight of the CO2 generated was estimated to be 94 g. The efficacy of yeast-generated CO2 as attractant for mosquitoes was significant, and the following 6 mosquito speci...
متن کاملConvenient method for synthesis of a carbon-14 analogue of DL-Phenyl alanine
DL-Phenyl alanine labeled with carbon-14 in the α-position has been synthesized from ethyl[2-14C] acetate as part of a 6-step sequence.
متن کاملHuman placenta as a convenient source of creatine kinase BB.
We demonstrate that human placenta is a convenient source of creatine kinase isoenzyme BB. We compare the physicochemical and catalytic properties with those of other creatine kinase isoenzymes: purified human abdominal muscle MM and brain BB. We also describe a stabilizing medium for creatine kinase BB. Human placental and brain BB have similar catalytic properties, the respective Km values fo...
متن کاملA CONVENIENT SYNTHESIS OF MACROCYCLIC DIAMIDES
Some new macrocyclic dibenzotrioxadiamides, dibenzotetraoxadiamide, dibenzopentaoxadiamide, dibenzothiatrioxadiamide, tribenzotrioxadiamides and tetrabenzohexaoxadiamide (14-21), (26) and (27) have been prepared. These compounds were obtained in the macrocyclization step by reacting the diamine (4) with appropriak dicaxboxylic acid dichlorides (5-13) and (24). The cyclization does not requ...
