Abstract: A method of treating a subterranean formation. The method may include providing a well treatment including a treatment complex formed of a treatment agent encapsulated, entrapped, or embedded in a polysaccharide, introducing the treatment complex into a wellbore through a subterranean formation, and allowing the treatment complex to release the treatment agent over a release time period. The method may include allowing the treatment complex to release the treatment agent after a delay time period from the introduction of the treatment complex into the wellbore.

Abstract: A method of purifying ammonia borane is provided whereby crude ammonia borane is dissolved in a basic aqueous solution, the solution is heated to decompose and precipitate impurities found in the crude ammonia borane, and the impurities are separated by filtration. The aqueous solution containing dissolved ammonia borane is then cooled to a temperature of from 10° C. to ?10° C., to precipitate the ammonia borane, which is recovered and dried to yield a high-purity product.

Abstract: A venting apparatus includes a projecting member with a projection base, and a mating socket member with a socket base, and first and second ducts in fluid communication with an appliance to vent emissions along an emission flow path. The projection base engages a first one, and the socket base engages a respective other one, of the first and second ducts. The projecting and socket members have default configurations. The projecting member is movable from the default configuration towards a deflected configuration, and biased for return therefrom. The first and second ducts are movable between sliding and locked configurations. In the sliding configuration, the projecting and socket members bear against one another, with the projecting member removed from the default configuration. In the locked configuration, the projecting member is in the default configuration, and secured to the socket member, such that the second duct securely engages the first duct.

Abstract: An improved process for making 5,11-dihydro-11-ethyl-5-methyl-8-{2-{(1-oxido-4-quinolinyl)oxy}ethyl}-6H-di pyrido[3,2-b:2?,3?-e][1,4]diazepin-6-one.

Abstract: A process for making nevirapine, comprising the following steps: (a) reacting a 2-halo-3-pyridinecarbonitrile of the formula wherein X is a fluorine, chlorine, bromine or iodine atom, preferably chlorine or bromine, with cyclopropylamine, to yield 2-(cyclopropylamino)-3-pyridinecarbonitrile; (b) hydrolyzing the 2-(cyclopropylamino)-3-pyridinecarbonitrile to yield 2-(cyclopropylamino)-3-pyridine carboxylic acid; (c) isolating the 2-(cyclopropylamino)-3-pyridine carboxylic acid from the reaction medium; (e) treating the 2-(cyclopropylamino)-3-pyridine carboxylic acid with a chlorinating agent, to yield 2-(cyclopropylamino)-3-pyridinecarbonyl chloride; (f) reacting the 2-(cyclopropylamino)-3-pyridine carbonyl chloride with a 2-halo-4-methyl-3-pyridinamine of the formula wherein X is a fluorine, chlorine, bromine or iodine atom, preferably chlorine or bromine, to produce an N-(2-halo-4-methyl-3-pyridinyl)-2-(cyclopropylamino)-3-pyridinecarboxamide; and (g) cyclizing the N-
