The pre-composting process of inked waste paper serves to reduce Pb levels in compost raw materials the form by using (lead) degradation agents corn cob charcoal, activated PGPR and cow rumen liquor. This study intends ensure quality after being given pb agents. test AAS (Atomic Absorbtion Spectrophotometer) method cellulolytic bacteria pour plate method. data were statistically tested with Ano...

This case study of a cell culture process development lab shows how various common analytical instruments were quickly and effectively integrated into a comprehensive process control and data management system. Streaming time-stamped results from these instruments directly into the process control system enabled automated real-time feedback and advanced characterizations of cell viability, inst...

PURPOSE To learn how the local context may affect a city's ability to regulate alcohol products such as high-alcohol-content malt liquor, a beverage associated with heavy drinking and a spectrum of nuisance crimes in urban areas. APPROACH An exploratory, qualitative case study comparing cities that adopted policies to restrict malt liquor sales with cities that considered, but did not adopt p...

Keep in mind the importance of cadmium, cobalt and nickel ions as environmentally and economically strategic heavy metals, the application of two acidic extractants, named bis(2-diethylhexyl)phosphoric acid (DEHPA) and 2-thenoyltrifluoroacetone (HTTA), was assessed for the extraction-recovery of these ions from leached solution of spent rechargeable Ni-Cd batteries. The conditions for leach...

Our objective is to estimate the relative price elasticity of demand for malt liquor beer (MLB), regular beer, hard liquor, and a combined group of all other alcoholic beverages. Three hundred and twenty-nine alcohol consumers (mostly male) in South-Central Los Angeles answered a series of questions pertaining to expected consumption responses to hypothetical price increases. We found that base...

The accuracy of predicting fetal maturity by ultrasound cephalometry, radiology, and liquor studies in patients with unknown confinement dates has been compared. The best prediction was given by ultrasound cephalometry. Liquor studies were least helpful.

Some treatment plants in operation have not been designed to fulfill the required standards of phosphorus removal. A possibility to upgrade the efficiency of phosphorus removal could be elimination of the phosphorus returned with sludge processing liquors by releasing and recovering from sewage sludge. The phosphorus recovery can occur from sewage sludge by chemical methods or from supernatant ...

A new kind of retarding polycarboxylate superplasticizer (M20S80) was prepared through the modification of black liquor and polycarboxylate superplasticizer (S) through an Fe-H2O2 reaction system. The synthesis process of M20S80 was introduced. Infrared spectrum analysis (FT-IR) was used to investigate the changes in functional groups in M20S80. At the same time, a mixture of LM20S80 was made b...

A scalable new mathematical model based on the principles of Process Integration has been developed for the analysis of multiple effect evaporator (MEE) systems. It uses the concepts of stream analysis, temperature path and internal heat exchange for the formulation of model equations. In addition to above the model also takes into account variable physico-thermal properties of steam/vapor, con...
