triacylglyceride composition of cottonseed oil by hplc and gc

the triacylglyceride components of cottonseed oil were isolated and positively identified by a combination of high performance liquid chromatography (hplc) and gas chromatography (gc). both reversed-phase hplc and capillary gc were capable of separating the oil into triacylglyceride peaks. these peaks were isolated by hplc, and their comp..

cleaning system for optimum raw materials utilisation

the function of the 'pneuma-reiniger' coarse dust separator is to remove coarse impurities and heavy particles. up to about 10 of the impurities present in the wastes are separated and removed from the cotton by purely mechanical means in this unit. the task of the next cleaning unit in the line is thus made easier and it prevents coarse ..

diffusion processes during formation of low linear density polyacrylonitrile fibers

solvent content effect on precipitation diffusion properties of binary and ternary acrylonytrile copolymers in spinning bath has been studied. the method of finishing optical boundaries (trickling method) has been applied. threshold concentration of the solvent is estimated for the polymer - solvent - precipitant system relationship betwe..

appliance to standard medical centrifuge, functionally replacing special device for cotton cork production, is presented general view and drawings of the appliance are given. the structure is designed in form of foundation mounted on a centrifuge shell and table fixed on columns by scorns and lifted by handle. needle with a ristrictor is ..

bronchial reactivity among cotton workers in relation to dust and endotoxin exposure

bronchial reactivity was measured before work among non-smoking female and male workers from carding, spinning, warping and weaving areas in a cotton mill. airport baggage loaders were used as controls. the amount of dust and endotoxin was measured at the different workplaces. statistically significant decreases in fev//1 were found betwe..

briquettability of the kirghiz brown coals with cotton tar

possibility of production of briquettes with the bonds from brown coals of almalyks, adulaksk and karachinsk fields of kyrgyzstan has been studied under laboratory conditions. usage of cotton tar and fatty tar of oil-fat combinates as an emulsion permits to produce qualitative briquettes from brown coals. cost of briquettes decreases as t..

influence of harvest factors on cotton yield and quality

research studies were conducted during the 1980s to evaluate the relationship between harvest systems, harvest aid chemicals, and harvest environments to cotton yield and quality. cotton yield and quality were reduced in three out of five years with once over and delayed harvesting compared to twice over harvesting. the most significant f..

the textile industry is one of the earliest industries to occur in many developing countries. this paper attempts to analyze the relevance to developing countries of alternative technologies available for different stages of textile manufacture. the scope is restricted to the main apparel fibres cotton and manmade fibres. the discussion i..

industrial recovered-materials-utilization targets for the textile-mill-products industry

the congress, in the national energy conservation and policy act of 1978 (necpa), directed the department of energy to establish materials recovery targets for the metals and metal products, paper and allied products, rubber, and textile-mill-products industries the targets were developed to provide incentives for using energy-saving reco..

hybrid fuels for highway transportation. second annual technical progress report for the period 1 june 1979-1 june 1980

a program has been developed to investigate the potential of hybrid fuels for use in highway transportation. hybrids are fuels derived from combinations of readily available energetic non-conventional materials with petroleum. they are generally formulated as solutions, emulsions, or slurries. the underlying objective of the program is to..
