upgrading of low-grade jute and cuttings part ii: interaction between jute fibres and microbial enzymes

an investigation is reported in which two isolated strains, a niger and a. terreus, exhibited similar enzyme activity, but a. niger showed the maximum pectinlyase activity (acidic). an enzyme extract of both the strains and commercial enzymes (flaxzyme and bioxylanase) softened jute cuttings within 24 hours. the physico-mechanical propert..

molecular resolution images of enzyme-containing langmuir-blodgett films

langmuir-blodgett technology has been used for fabricating systems consisting of mixed layers of behenic acid and glucose oxidase. these systems have been imaged by atomic force microscopy at a molecular level. the observation of these samples shows the presence of the glucose oxidase molecules organized in parallel ridges, and individual..

brush-type stripper for double-row cotton

a brush-type stripper was modified to fit double-row plantings having the two rows on each bed 30 to 40 cm apart. performance characteristics were compared with those of a finger-type stripper during two seasons of field testing. the brush stripper proved to be more tolerant of adverse conditions and had lower field losses, less trash wit..

toxaphene washoff from cotton plants by simulated rainfall

agricultrual chemical transport modeling requires predicting insecticide washoff by rainfall from plant canopy to soil and its subsequent transport in runoff and sediments. one such chemical, toxaphene (chlorinated camphene), is applied to cotton for insect control in the south during july and august, months of high-intensity thunderstorm..

cotton harvesting decision aid model

this paper describes the harvesting analysis simulation program (hasp) developed at texas tech university. the primary purpose of hasp is to provide an estimate of cotton harvest operation costs arising from the use of a specified set of equipment under specified conditions. harvesting and ginning operations are simulated on a daily basis..

influence of temik (aldicarb) on herbicide persistence in cultivated cotton field soil under field conditions

the effect of the insecticide temik on the persistence of the herbicides cotoran and cobex was investigated in cultivated cotton fields. temik was applied to the soil which had also been treated with cotoran or cobex. residues were determined at 15 day intervals for four months. temik was found to inhibit the degradation of both compounds..

prefacturing pressure transient testing: east texas cotton valley tight gas play

one of the low permeability gas plays that amoco is currently developing is the cotton valley sands of east texas. this study presents certain aspects of amoco's prefracturing pressure transient testing experience in the cotton valley. it covers the objectives and reasons for testing, test design, mechanical aspects of testing, and data a..

module system of handling and storage of seed cotton

a complete system of handling and storage of seed cotton has been developed. the system consists of a mechanized module builder, pallets, handling and transport system and a mechanized gin feeder the cotton is formed into a free standing stack by the module builder that compacts the cotton as it is received with a traversing compactor. th..

further studies of the fractorgraphy of cotton fibers

the authors' previous work on the fractography of cotton has been extended to include a comparison of cotton varieties, differences between individual fibers of different strength, fracture of mercerized cotton in water, fracture of crosslinked cotton (including tests in water, and at and between reversals), fractures at different tempera..
