Aerobic, anoxic, and anaerobic selectors have become popular for controlling filamentous bulking in activated sludge systems; however, selectors are not always successful. Regression analyses of data collected from 48 full-scale wastewater treatment plants, with operating selectors, provided a method for ranking the importance of selector operating and design parameters (with respect to their i...

Levamisole has been implicated in the vasculitis and aganulocytosis. It has been pulled from the United States market for human use. Due to its euphoric and bulking properties, it has been . used as a bulking agent in cocaine. We hereby present a case of a 56-year-old Hispanic male, who developed vasculitis due to cocaine use adulterated with levamisole.

This study investigated the effects of different proportions (0%, 5%, 10%, 15%) bulking agent (vinasse, mushroom bran, and tobacco powder) on maturity gaseous emissions in chicken manure composting. The results showed that all treatments reached standard harmless disposal. With exception control treatment, CH4, N2O, NH3 had been prepared using addition mixed agents were effectively reduced by 2...

Introduction The purpose of this systematic review is to evaluate whether implantable versus injectable bulking agents (second-line therapies) are equal/superior in terms effectiveness (severity, quality life [QoL], sustainability) and safety (adverse events) for fecal incontinence (FI). Methods A was conducted five databases were searched (Medline via Ovid, Embase, Cochrane Library, University...

Undesirable taste is one of several important formulation problems that are encountered with certain drugs. The problem of bitter and obnoxious taste of is a challenge to the pharmacist in the present scenario. Several oral pharmaceuticals and bulking agents have unpleasant, bitter-tasting components. The desire of improved palatability in these products has prompted the development of numerous...

Sludge bulking causes loss of biomass in the effluent and deterioration of effluent water quality. This study explored the use of nano zero-valent iron (NZVI with an average particle size of 55 ± 11 nm) for sludge bulking control. In two Modified Ludzack-Ettinger (MLE) activated sludge treatment systems, a single dose of NZVI at the final concentration of 100 mg Fe per L in the mixed liquor red...

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of nylon polymers, which function in cosmetics primarily as bulking and opacifying agents. The Panel reviewed relevant animal and human data related to these large polymers and determined that they are not likely to penetrate the skin. Whatever residual monomers may be present were not present at a sufficient level to cause...
