Pitch control is one of t he  major aspects of wind turbine control, particularly over high wi nd s p e e d  a n d  oscillations. General El e c t r i c  (GE) model of  wi n d  t ur bi ne  i s practically compatible with the structure of the wind turbines. I t  h a s  b e e n  p r o v e d t h a t  simulation results using this model are closer to the actual case, compared to other available mod...

Porphyromonas gingivalis biofilms are implicated in the pathology of peri-implantitis and periodontitis. In this study, D-arginine (R), D-methionine (M), D-histidine (H), a mixture these D-amino acids (D-AAs) were investigated as an effective therapeutic strategy against P. biofilms. The bacterial growth activity minimum inhibitory concentrations determined for each D-AA, along with effects D-A...

as a continuous research for discovery of new cox-2 inhibitors, chemical synthesis, in vitro biological activity and molecular docking study of anew group of 1,4-dihydropyridine (dhp) derivatives were presented. novel synthesized compounds possessing a cox-2 so2me pharmacophore at the para position of c-4 phenyl ring, different hydrophobic groups (r1) at c-2 position and alkoxycarbonyl groups (...

urinary 1-hydroxypuren (1-ohp) is commonly used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons (pahs). for evaluation of human exposure to such compounds, biological monitoring is an essential process, in which, preparation of samples is one of the most time-consuming and error-prone aspects prior to chromatographic techniques. in this...

introduction: in continuation of recent development of possible c-x-c chemokine receptor type 4 (cxcr4) imaging agents, we report the development of a possible cxcr4 targeted therapy agent. methods: [153sm]labeled 1,1′-[1,4-phenylenebis(methylene)] bis-1,4,8,11-tetraazacyclo -tetradecane ([153sm]-amd3100) was prepared using [153sm]smcl3 and amd-3100 for 24h at 50°c in acetate buffer.stability ...

rapid and highly efficient synthesis of 2- or 2,5-substituted 1,3,4-oxadiazoles by the condensation of aryl carboxylic acid hydrazides and orthoesters can be achieved under microwave irradiation using an unmodified commercial over in unsealed vessels.

The present study was aimed to determine the protective effects of Plantago major L (PM) leaf extracts on the testicular torsion/detorsion (T/D)-induced ischemia/reperfusion (I/R) injury in rats. Twenty-four mature male Sprague-Dawley rats, weighing 200-220 g, were selected. They were randomly divided into four groups of six animals each: Sham (sham-operated rats; all the surg...
