TL;DR: Cholestyramine-pretreatment seemed to be a suitable experimental model for the depletion of bile acids in rat bile.
Abstract: Bile flow and biliary excretion of dihydroxy- and trihydroxy-bile acids have been determined in control, cholestyramine (250--2000 mg/kg p.os)- and aluminium hydroxide (250--2000 mg/kg p.os)-pretreated rats. Cholestyramine proved to be a more potent bile acid depleting agent than aluminium hydroxide. The depressing effect of cholestyramine on bile flow was also more significant than that of aluminium hydroxide. Cholestyramine-pretreatment seemed to be a suitable experimental model for the depletion of bile acids in rat bile.

TL;DR: In this paper, a preparation method of an expanding type halogen-free organic fire-proof blocking material was proposed, which comprises the following steps of: selecting raw materials of aluminium hydroxide, ceramic powder, expanding type graphite, iron oxide red, dioctyl phthalate, zinc borate, alumina silicate fibre, acrylic resin, dibutyl phthate, polyamide resin 650, gaseous phase white carbon black and ammonium polyphosphate in a certain ratio.
Abstract: The invention relates to a preparation method of an expanding type halogen-free organic fireproof blocking material. The preparation method comprises the following steps of: selecting raw materials of aluminium hydroxide, ceramic powder, expanding type graphite, iron oxide red, dioctyl phthalate, zinc borate, alumina silicate fibre, acrylic resin, dibutyl phthalate, polyamide resin 650, gaseous phase white carbon black and ammonium polyphosphate in a certain ratio; mixing and stirring the polyamide resin 650, the dioctyl phthalate, the gaseous phase white carbon black, the ammonium polyphosphate and the dibutyl phthalate to obtain bonded resin; placing the aluminium hydroxide, the ceramic powder, the expanding type graphite and the iron oxide red into a stirring machine to stir; adding the bonded resin and the acrylic resin into a premixed filler to mix and stir into a viscous soft ball-like substance; and placing the viscous soft ball-like substance in the above procedure into an extruder to perform extrusion molding. By the preparation method, the defect that irritant gases and smoke generated by the conventional organic fireproof blocking material under the action of a fire disaster penetrate holes to diffuse and spread all around is overcome; and the problems of damage to a human body and corrosion to equipment caused by toxic halogen acid hydrogen are solved.

TL;DR: In this paper, a method of synthesizing the T type zeolite membrane by the microwave heating method is characterized in including the major steps as follows: (A) preparing the seed crystal porous basal membrane: mixing the t type zeolate seed crystal with the distilled water, ultrasonic dispersing into even zeolate suspension, and forming a layer of evenly distributed zeoline seed crystals on the basal membrane by dip coating method.
Abstract: A method of synthesizing the T type zeolite membrane by the microwave heating method is characterized in including the major steps as follows: (A) preparing the seed crystal porous basal membrane: mixing the T type zeolite seed crystal with the distilled water, ultrasonic dispersing into even zeolite suspension, and forming a layer of evenly distributed zeolite seed crystals on the basal membrane by the dip coating method; and (B) synthesizing the T type zeolite membrane: fixing the seed crystal basal membrane, synthesizing by the conventional hydrothermal method, and synthesizing by the microwave heating; and taking out, cooling, washing with the distilled water to neutrality, and drying. The alkali source is sodium hydroxide, potassium hydroxide, etc. The silicon source is silica sol, sodium silicate, white carbon black, etc. The aluminum source is aluminium hydroxide, sodium aluminate, aluminum sheet, etc. The preparation method of the zeolite membrane has greatly shortened synthesis time compared with the conventional heating synthetic method. The synthesized T type zeolite membrane has excellent alcohol/water pervaporation property, and high synthesis repeatability.

TL;DR: In this paper, a process for the preparation of polyaluminium hydroxychloride complexes having the general formula Al(OH)xCly in solution or in solid form and intended to be used as flocculants and coagulants at water purification, sludge dewatering and paper production is described.
Abstract: The present invention relates to a process for the preparation of polyaluminium hydroxychloride complexes having the general formula Al(OH)xCly in solution or in solid form and intended to be used as flocculants and coagulants at water purification, sludge dewatering, plant dewatering and paper production, whe-reby one reacts aluminium chloride in solution with aluminium hydroxide, or aluminiumoxide hydrates at a temperature of 120-170°C at an elevated pressure for 1.5-5 hrs, whereby the rela-tionship AlCl3:Al(OH)3 is thus adjusted that the relationship OH:Al in the resulting compound Al(OH)xCly becomes 0.5 to 1.5, preferably 0.8 to 1.2.

TL;DR: In this paper, a method for increasing electric strength of highvoltage insulation in humid environment consists of applying, to the surface of the insulating element, hydrophobic coating consisting of organic-silicon material with addition of titanium dioxide, which solidifies at a normal temperature.
Abstract: The proposed method for increasing electric strength of high-voltage insulation in humid environment consists inn applying, to the surface of the insulating element, hydrophobic coating consisting of organic-silicon material with addition of titanium dioxide, which solidifies at a normal temperature. The said material is diluted with organic solvent mixed with low-molecular organic-silicon liquid with addition of aluminium hydroxide.
