Mathematical modeling assisted investigation of forward osmosis as pretreatment for microbial desalination cells to achieve continuous water desalination and wastewater treatment by Yuan, Heyang

“…When further tested with actual domestic wastewater amended with glucose and NaHCO3, the FO-MDC system generated a desalinated effluent containing 1130mgTDSL-1. The results of this study suggest that proper coordination of the treatment capacity of the two membrane-based treatment processes could create a potentially effective system for wastewater reuse and seawater desalination.…”

Production of phycocyanin by Leptolyngbya sp. in desert environments by Schipper, Kira

“…Increasing temperatures were found to improve the biomass productivity and phycocyanin content, which, at 40 °C, were 1.09 ± 0.03 gX·L−1·d−1 and 72.12 ± 3.52 mgPC·gX−1, respectively. The optimum biomass productivity was found at a light intensity of 300 μmol·m−2·s−1, with higher light intensities causing a decrease of 15%. …”

Effects of the P20 protein from Bacillus thuringiensis israelensis on insecticidal crystal protein Cry4Ba by Jaoua, Samir

“…The combination of P20 protein with Cry4BLB delta-endotoxin led to a stable mortality rate of 25% with doses ranging from 0.2 mg l−1 to 0.6 mg l−1. Cry4BLB crystals produced in the presence of P20 were much less soluble than those produced by the control strain lacking P20 at pH lower than or equal to 10.5. …”

Acute mercury toxicity modulates cytochrome P450, soluble epoxide hydrolase and their associated arachidonic acid metabolites in C57Bl/6 mouse heart by Amara, Issa E.A.

“…Mercury toxicity was induced by a single intraperitoneal injection (IP) of 2.5mg/kg of mercuric chloride (HgCl2). Our results showed that mercury treatment caused a significant induction of the cardiac hypertrophy markers, atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP); in addition to Cyp1a1, Cyp1b1, Cyp2b9, Cyp2b10, Cyp2b19, Cyp2c29, Cyp2c38, Cyp4a10, Cyp4a12, Cyp4a14, Cyp4f13, Cyp4f15, Cyp4f16 and Cyp4f18 gene expression. …”

Impact of combined oil-in-water emulsions and particulate suspensions on ceramic membrane fouling and permeability recovery by Abdalla M.

“…Results showed the addition of suspended solids to the o/w emulsion to be extremely deleterious to sustaining both the permeability and selectivity of the membrane. The addition of 1500 mg·L−1 of bentonite to a 10 vol.% emulsion resulted in a permeability decrease of 3.5–5 times over that recorded for the emulsion, and 8–36 times lower than that of the bentonite suspension. …”
