Kaolin is an industrial mineral used in a wide variety of applications due to its crystalline structure, and elemental composition. After kaolin undergoes heat treatment specific temperature range, metakaolin, which exhibits strong pozzolanic reaction, formed. This paper examines the effects different qualities on thermal activation process metakaolin production. The depend impurities they cont...

Abstract Lettuce is a crop sensitive to water availability as it needs more in cultivation. Kaolin has been reported reduce the impact of drought stress plants. However, use kaolin increase lettuce growth under condition not yet. In this study, effect suboptimal watering was investigated. foliar application (3%, 5%, and 6%) tested on group consisting 5 plants grown reduced greenhouse. height, n...

Unhydrated aminopropyl triethoxysilane was used to modify calcined kaolin produced from coal-bearing kaolinite. The aim develop a simple and economic modification method without the need for solution immersion subsequent wastewater treatment. samples before after were tested using multiple methods, such as XRD, MAS-NMR, FT-IR, XPS, SEM. study results indicate that this can effectively improve s...

Thirty patients with systemic lupus erythematosus (SLE) and suspected secondary antiphospholipid antibody syndrome (APLAS) were evaluated in the study based on their clinical manifestations. The aim was to study the prevalence of various antiphospholipid antibodies, compare the tests used for their detection and to find a correlation between clinical and laboratory parameters. Coagulation tests...

1. The unsaturated lipoids (serum antitrypsin) can be adsorbed from guinea pig serum, rabbit serum, and horse serum by kaolin, starch, agar, and bacteria. 2. Diphtheria toxin and cobra venom also reduce the serum antitrypsin, possibly because of their affinity for lipoids. 3. Anaphylatoxins represent sera rendered toxic by partial removal of serum antitrypsin. 4. The matrix of the protein split...

Klebsiella pneumoniae H12 produced a newly identified extracellular polysaccharide in an ethanol medium with a yield of 3.0 g/l. The molar composition of the polysaccharide was 56.04% galactose, 25.92% glucose, 10.92% galacturonic acid, 3.71% mannose, and 3.37% glucuronic acid. The addition of 0.5%-1.5% NaCl increased production. The polysaccharide flocculated with kaolin clay in suspension at ...

The full elastic tensors of the sheet silicates muscovite, illite-smectite, kaolinite, dickite, and nacrite have been derived with first-principles calculations based on density functional theory. For muscovite, there is excellent agreement between calculated properties and experimental results. The influence of cation disorder was investigated and found to be minimal. On the other hand, stacki...

PURPOSE The aim of this study was to assess the pharmacophysiological significance of the enteric nervous system for the mechanical responses of lower esophageal sphincter (LES) in infantile rats with kaolin-induced hydrocephalus. MATERIAL AND METHODS Hydrocephalus was created in 7-day-old rats by injection of kaolin into the cisterna magna. After 10 days, rats were decapitated. Contractile (...

This study deals with the behaviour of mixtures of sand and saturated kaolin paste considered as composite materials made of permeable and deformable (with non-linear behaviour) matrix (the kaolin paste) with rigid and impervious inclusions (the sand grains). Oedometric and permeability tests conducted on such mixtures highlight the key role of the state of the clay paste, and show the existenc...

Blood plasma obtained from an individual with abnormal thromboplastin formation, due to deficiency of Fletcher factor, was fully corrected by 2% of normal, Hageman factor- or PTA-deficient plasma. It was also reconstituted by addition of highly purified human or rabbit prekallikrein. The plasma failed to generate kinin upon exposure to kaolin, a defect which was also corrected by addition of pr...
