This SafetyNet suggests chemical substitutes for commonly used chemicals to promote a safer work environment. Consider using the safer substitute if it works in your process: Sample of Chemical Substitute List. View full list here [1].

Refrigerants that are used in refrigeration systems, cause environmental difficulties such as depletion of ozone layer and greenhouse effect. Thus, we must find substitutes for such refrigerants, in this paper, the effect of refrigerant on the thermodynamics performance of refrigeration cycles are studied. To do this, a refrigerator that has designed for R12, is simulated. Results show that pur...

Growth behavior of Clostridium botulinum type E beluga was studied in Acipenser persicus granular caviar treated with 5% NaCl, 5%NaCl plus 0.3% boric acid and 0.4%borax and 5%NaCl plus 0.15% methyl paraben incubated at temperatures -2, 5 and 15 °C for 224 days. The initial number of inoculated bacterial spore was 5.1×104 cfu/g caviar in each treated sample. The number of bacterial spores in sam...

labeling system for all exports. While CITES deliberates, Russian reports suggest that the Caspian nations will lobby for an increased quota, following their meeting in Moscow earlier this month. The Caspian nations’ reprieve comes as the community awaits word of a decision by the U.S. Fish and Wildlife Service to list beluga as endangered. Such a ruling, now 2 months overdue, would ban all imp...

Modelling criminal trial verdict outcomes using social network measures is an emerging research area in quantitative criminology. Few studies have yet analyzed which of these measures are the most important for verdict modelling or which data classification techniques perform best for this application. To compare the performance of different techniques in classifying members of a criminal netwo...
