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...

Abstract This experiment was conducted to determine the effect of kaolin clay application and deficit irrigation on quantitative characteristics pumpkin in a field located Siahbaz village Khoy, Iran. In order investigate yield components ( Cucurbita pepo L.), this experimental considered. An performed with at four levels (complete irrigation, from shoot stage, flowering stage seed filling stage...

The isolation and characterization of the first component of the kinin-forming system in human and rabbit plasma are presented. Functionally, the molecule is the precursor of the activator of prekallikrein (Pre-PKA) and evidence is presented that it is identical with Hageman factor (clotting factor XII). The component from each plasma possessed similar characteristics. This molecule was found t...

This paper presents a systematic bench-scale laboratory study performed to assess the transient behavior of chromium, nickel, and cadmium in different soils during electrokinetic remediation. A series of laboratory electrokinetic experiments was conducted using two different clayey soils, kaolin and glacial till. For each type of soil, four electrokinetic experiments with 1, 2, 4, and 10 d of t...

the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...

Background: Curcumin is yellow pigment of tumeric, and, that is extracted from it lawsonia (2-hydroxy 1,4 naphtoquinon) is a natural product and it is extracted from henna. Ginger is a dried rhizomes gained from a plant called zingiber officinalea, which is extracted from the family of ginger. Material and Methods: This experimental study performed on adult male rats. Acute inflammatory edema ...

sunburn damage is a physiological disorder, which reducing pomegranate fruits quality and result to huge loss to the gardeners yearly. in this study, the effects of kaolin on maintaining fruit quality and decreasing sunburn damage of malas-e-torsh-e-saveh pomegranate was investigated. processed kaolin (surround® wp) with 0, 2.5, 5 and 10 % (w/v) was sprayed over the whole canopy and fruits at 4...

A patient is described who had a long history of abuse of kaolin and morphine mixture which ultimately proved fatal.

Results: Mean ACT value was 180±24 seconds. Femoral hemostasis was achieved with a double suture-based VCD deployment in 30 (67%) patients or a double VCD with cross-over balloon inflation in the remaining 15 (33%) patients. Bleeding after VCDs occurred in 15 (33%) pts. The kaolin-based dressing, activates the intrinsic blood coagulation pathway thus allowing for a short manual hemostasis perio...

The deflocculation effect of conventional additives to kaolin suspensions is evaluated from the results standard rheological measurements. Several widely used electrolytes (NaOH, Na2C03, Na2Si03, SHMP = sodium hexametaphosphate, and CMC = sodium salts of carboxymethylcellulose) have been tested. The optimal concentrations of these deffloculants, in respect to reaching the maximum reduction of i...
