Hierarchical faujasite zeolites made up of nanoparticle aggregates (NAs) and layer-like structures (LL) are evaluated for xylene adsorption in both gas liquid phases. For NA zeolites, several samples with varying external surfaces meso/macropore volumes considered. Compared to conventional faujasite, isotherms as measured by means thermogravimetric experiments display higher capacities the fauj...
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Objective(s) In recent years highly selective COX-2inhibitors were withdrawn from the market because of an increased risk of cardiovascular complications. In this study we were looking for potent compounds with moderate selectivity for cox-2. So, four analogues of 4, 5-diaryl-2-(2-alkylthio-5-imidazolyl) imidazole derivatives were synthesized and their anti-inflammatory and anti-nociceptive ac...
Frequency modulation (FM) is computed from the temporal sequence of activated auditory nerve fibers representing different frequencies. Most studies in the inferior colliculus (IC) have inferred from extracellular recordings that the precise timing of nonselective inputs creates selectivity for FM direction and velocity (Andoni S, Li N, Pollak GD. J Neurosci 27: 4882-4893, 2007; Fuzessery ZM, R...
In situ(11)B NMR monitoring, computational modeling, and external trapping studies show that selectivity and extent of H(2) release in metal-catalysed dehydrogenation of ammonia borane, NH(3)BH(3), are determined by coordination of reactive aminoborane, NH(2)BH(2), to the metal center.
Mazindol has been explored as a possible agent in cocaine addiction pharmacotherapy. The tetracyclic compound inhibits both the dopamine transporter and the serotonin transporter, and simple chemical modifications considerably alter target selectivity. Mazindol, therefore, is an attractive scaffold for both understanding the molecular determinants of serotonin/dopamine transporter selectivity a...
