The needs for safe, therapeutically effective antidiarrheal combination continuously lead to effective treatment. When administered simultaneously, metronidazole-kaolin interactions have been reported by FDA but not studied. This paper is the first to study metronidazole-kaolin interactions. Adsorption isotherms of a metronidazole-kaolin antidiarrheal combination from aqueous solutions at an in...

Apoptosis was measured in rat alveolar macrophage NR8383 cells challenged in vitro with respirable quartz or kaolin dust and with the dusts pretreated with dipalmitoyl phosphatidylcholine (DPPC) to model conditioning of respired dusts by interaction with a primary phospholipid component of pulmonary surfactant. Quartz dust is known to induce apoptosis in vitro and in vivo. For this study, quart...

The paper reports a process for synthesis of γ-alumina from kaolin. Kaolin was transformed to meta-kaolin by calcination at 800 ̊C for 2h. γ-alumina powder was synthesized through extracting alumina from metakaolin via H2SO4 and meta-kaolin reactions and consequently precipitation in ethanol, which led to form the aluminum sulfate. The precipitated aluminum sulfate was dried and calcined at 900 ̊...

Both aprotinin and in vitro heparin and protamine dosing assays (RxDx System) have been shown to reduce postoperative bleeding in the cardiac surgery patient. While celite activated clotting time tests in the presence of heparin are artificially prolonged by aprotinin, the kaolin based ACT is not. In order to optimize heparin anticoagulation management during cardiac surgery when aprotinin is u...

Introduction: Inferred paleolakes on the surface of Mars are key targets for astrobiology. To date, pale-olakes have been identified primarily based on mor-phologic evidence, including inlet and outlet channels, deltas, and horizontal bedding in closed basins [1-3]. Clay minerals have been identified in some of these settings, but these may be detrital [4]. Other alteration products such as eva...

High production of biodiesel results in a surplus glycerol as byproduct that leads to drastic decline the price well overall production. Alternative methods must be introduced for economical process via utilization crude into valuable chemicals or fuel additives. This study introduces an ecofriendly solketal synthesis from and acetone presence novel metakaolin clay catalyst, which is useful add...

This paper presents the results of consolidated and undrained (CU) triaxial cyclic tests related to influence tire waste addition on strength characteristics two different soils from Southern Poland: unswelling kaolin swelling red clay. The test procedure included normally remolded specimens prepared pure clay (RC) (K) their mixtures with fractions shredded rubber powder (P) granulate (G) in 5%...

Natural gas hydrates exist in large quantities nature and represent a potential source of energy, mostly the form methane gas. Knowledge about hydrate formation clayey sand is importance for understanding production from reservoirs, as well impact global warming on stability subsurface hydrates. In this paper, we explore effect clay content phase transitions unconsolidated at realistic reservoi...

Formulation of traditional hard porcelain generally requires 50% kaolin, 25% silica and feldspar. Four porcelains formulation using the casting method, were prepared with different percentages kaolinitic clay, sand pegmatite referenced respectively NONG, SAB PEG. The physico-chemical, mechanical mineralogical characteristics evaluated on specimens formulated sintered at temperatures from 1200?C...

We tested effects of kaolin particle film on oviposition, larval mining, and infestation of cotton by pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), in the laboratory, greenhouse, and field. In laboratory choice tests, females laid seven times more eggs on untreated bolls than on bolls treated with kaolin. When neonates were put on bolls in the laboratory, each b...
