This study examined the application of modified clay mineral waste material (MCMWM) for removal of phosphorus (P) from aquatic systems including surface water and wastewater related to the application of recycled solid waste materials. The effects of ionic strength and pH on P adsorption by MCMWM were investigated at pH values of 3, 5, 6, 7 and 9 with P concentrations of 10, 20, 40, 100 and 200...

Arsenic (As)-contaminated soil and water vary with pH and concentrations of As and P. This study examined the effects and interactions of three factors, pH, As and P, on As hyperaccumulator Pteris vittata L. to optimize plant growth and maximize As removal from contaminated sites, especially water. Two sets of hydroponic experiments were conducted using three-factor, five-level central composit...

background and aim(s): this in vitro study compared the effects of mineral trioxide aggregate (mta), calcium enriched mixture (cem) cement, biodentine (bd) and octacalcium phosphate (ocp) on the viability of human gingival fibroblasts (hgfs). material and methods: after completion of the setting time of understudy materials, fibroblasts were placed in 24-well insert plates and 1mg of the unders...

Biomaterials are increasingly used for bone tissue regeneration because of their potential to overcome the morbidity caused by autologous grafts and allografts. A combination properties is required, as biocompatibility, osteoconductivity, good mechanical strength fracture toughness. In this research, a compound alumina matrix with calcium titanate phosphate proposed. Magnesium stearate was poro...

The objectives of this study were to determine the influence of pH and MyHC isoforms on myofibrillar and actin-activated myosin subfragment 1 (S1) ATPase activity and the protective effect of actin. Red (RST) semitendinosus and white (WST) semitendinosus myofibrils were incubated at pH 7, 6, or 5.5 with 0 or 2mM ATP. RST and WST S1 isolates were incubated at pH 7, 6, or 5.5 in the presence or a...

Abstract The reaction of 5‐Ph 2 P‐Ace‐6‐Li (prepared in situ from 6‐Ph P‐Ace‐5‐Br and n ‐BuLi the presence TMEDA) with B(OMe) 3 B(O i ‐Pr) , respectively, provided boronic esters P‐Ace‐6‐B(OR) ( 1 a R=Me; b R= ‐Pr; Ace=acenaphthyl). Hydrolysis crude mixture afforded acid P‐Ace‐6‐B(OH) ), which crystallizes as hydrogen bonded complex ⋅ TMEDA CHCl . Condensation yielded related boroxine [5‐Ph P‐A...

A series of 1,4-phenylenes X-C(6)H(4)-BDB with a 1,3,2-benzodiazaborolyl (BDB) and a phosphorus based end group [X = PPh(2) (2), P(O)Ph(2) (3), P(S)Ph(2) (4), P(Se)Ph(2) (5), P(AuCl)Ph(2) (6) and P(Me)Ph(2) (7)] as well as 2-(2')thienyl-1,3,2-benzodiazaboroles with a second end group X [X = PPh(2) (8), P(S)Ph(2) (9), P(Se)Ph(2) (10) and P(Me)Ph(2) (11)] in the 5' position were synthesised using...
