One-dimensional nanostructures exhibit interesting electronic and optical properties due to their low dimensionality leading to quantum confinement effects. ZnO has received lot of attention as a nanostructured material because of unique properties rendering it suitable for various applications. Amongst the different methods of synthesis of ZnO nanostructures, the hydrothermal method is attract...

Fitzgerald trait, an asymptomatic disorder, is associated with abnormalities of surface-mediated plasma reactions, including coagulation via the intrinsic pathway, augmentation of the clot-promoting properties of factor VII, kaolin-mediated fibrinolysis, kinin generation, and enhancement of vascular permeability by diluted plasma (PF/Dil). These abnormalities can be corrected by Fitzgerald fact...

Incubation of normal human plasma with low amounts of sulfatides resulted in the initiation of intrinsic coagulation and the appearance of kallikrein activity. The optimal initiation of procoagulant and kallikrein amidolytic activity was dependent on the presence of factor XII, high molecular weight kininogen, and prekallikrein. Since the activated partial thromboplastin clotting times in preka...

AIM To describe the relationship between the parenchymal pressure changes and the development of hydrocephalus in kaolininjected neonatal rats according to cerebral regions and time intervals of developing hydrocephalus. MATERIAL AND METHODS Neonatal rats aged 2 to 3 days were examined in 5 groups as kaolin frontal "K-F", kaolin parietal "KP", saline frontal "SF-F", saline parietal "SF-P" and...

Kaolin-SO3H as a new solid acid is prepared via reaction of kaolin and chlorosulfonic acid. This natural based catalyst is very inexpensive and easy available. Imidazoles are an important class of heterocycles being the core fragment of different natural products and biological systems such as anti-allergic, anti-inflammatory, analgesic, antifungal, antimycotic, antibiotic, antiulcerative, anti...

Weathering of rocks generated large volumes of kaolin clays, quartz sands and micas, as well as other minerals, especially iron and titanium oxides. Kaolin is an economically important raw material often used in wide variety of ceramic applications, from high quality tableware and sanitaryware to electrical porcelain, tiles and glasses. There are some less common uses including glass fibre, whi...

long-chain diacrylate crosslinkers based on linear α,ω-diols were synthesized and characterized using ftir and 1h nmr spectroscopy. the highest reaction yield (99.5%) was due to polyethylene glycol diacrylate 1000 (pegda-1000). then, kaolin-containing poly(potassium acrylate-acrylic acid) superabsorbent composites and kaolin-free counterparts were synthesized using pegda-1000.the effect of the ...

In this paper presents the mathematical model of hydrothermal processes in thermal power plant with different wind direction scenarios in the water reservoir, which is solved by the Navier Stokes and temperature equations for an incompressible fluid in a stratified medium. Numerical algorithm based on the method of splitting by physical parameters. Three dimensional Poisson equation is solved w...

It is known that pica, the consumption of non-nutritive substances such as kaolin, can be induced by administration of toxins or emetic agents in rats. In the present study, we examined the effects of intraperitoneal (i.p.) administration of cyclophosphamide on pica behavior and on the concentration of 5-hydroxyindoleacetic acids (5HIAA) in cerebrospinal fluid (CSF) in the following five strain...
