Electrical resistivity evolution during precipitation in Al-Sc alloys is modeled using cluster dynamics. This mesoscopic modeling has already been shown to correctly predict the time evolution of the precipitate size distribution. In this work, we show that it leads too to resistivity predictions in quantitative agreement with experimental data. We only assume that all clusters contribute to th...

Pharmacological effects of camel urine (CU), its protein precipitate (PP), diluted urine (DU) and chloroformic extract (CE) were investigated. The PP inhibited the spontaneous movements of the isolated rat duodenum at a dose rate of 0.1ml/bath. Diluted female camel urine (0.4 ml/bath) or its protein precipitate (0.8 ml/bath) on rat fundus and rabbit jejunum revealed serotonin like effect which ...

distilled water it becomes cloudy owing to partial precipitation of the serum globulin. Under certain circumstances, a copious precipitate forms instead of a mere cloudiness. This precipitate is due to a globulin-like substance as is evident from the following facts:? (1) It is soluble in normal saline, in dilute acids, and in dilute soda bicarb, solution. It is also soluble in sodium hydrate s...

THE causes and mechanisms of urolithiasis are even nowadays not well understood. An increased concentration of crystalloids in urine as happens, for· example, in dehydration is one of the factors frequently cited. Randall (1937) drew attention to the importance of urinary tract infections as an initiating factor, and proposed that some stones started off as a plaque-like precipitate on the muco...

Precipitates of the ordered L12 ’ phase (dispersed in the face-centered cubic or FCC  matrix) were imaged in Rene 88 DT, a commercial multicomponent Ni-based superalloy, using energy filtered transmission electron microscopy (EFTEM). Imaging was performed using the Cr, Co, Ni, Ti and Al elemental L-edges in the energy loss spectrum. Manual and automated segmentation procedures were utilized f...

Experimental Section 1. Materials Melamine, sulfuric acid (H 2 SO 4) and triethanolamine were purchased from Chengdu Kelong Chemical Reagent Factory. Pluronic P123 was purchased from Aldrich. All reagents were used as received without further treatment. 2. Synthesis of mesoporous graphitic carbon nitride The following is a typical procedure for synthesis of worm-like mesoporous graphitic carbon...
