study of operating conditions of bar flatteners of no. 2 550-mm mill

causes of section straightener (mill 550-2) low reliability were studied. severe wear of rolls, frequent failure of individual units (particularly, spider of carbon shaft) as well as significant residual edge curvature of straightened channels are characteristic of operation of the above machines. analysis of section straightener operatio..

field evaluation of color/trash meters

two laboratory-type video color/trash meters were installed and evaluated in a commercial gin during the 1989 and 1990 ginning seasons. calibration of the meters was accomplished using manufacturer-supplied reference standards. during the 12-week ginning season each year, in which about 18,000 bales were ginned, the meters performed witho..

briquetting of carbonized cotton stalk

woody biomass, in the form of firewood and charcoal, is the main energy source in the sudan. agricultural residues in this country are assessed and their use as energy sources is investigated cotton stalks are produced in two large agricultural processes and have been used for this purpose. the conversion process of cotton stalks to usabl..

synthesis and properties of regular star polybutadienes with 32 arms

a dendrimer carbosilane containing 32 si-cl bonds in the perimeter has been prepared and has been used as a coupling agent to prepare 32-arm star polybutadienes. the dilute-solution properties $left angle bracket$ r//g**2 $right angle bracket$ , a//2, $left bracket$ $eta$ $right bracket$ , and d//0 have been measured in one good solvent a..

collection of spores of various fungi by a reuter centrifugal sampler

a method was developed to evaluate the performance of a reuter centrifugal sampler with respect to the relative and absolute efficiency of collecting fungal spores under controlled conditions species tested included penicillium viridicatum which has small subglobose spores and alternaria alternata which has larger irregular spores. the ex..

energetics of cotton agronomy

agronomic data from a sample hectare of cotton-growing area of our farm were examined for energy inputs, outputs and balance for comparison with monetary values. mechanized farming consumed about 45 of the energy inputs and accounted for about 20 of the expenses the major cost (53) was for manpower, which accounted for about 5 of the ener..

ultraviolet-radiation-induced graft copolymerization of styrene and acrylonitrile onto cotton cellulose

photoinitiated graft copolymerization of the vinyl monomers, styrene and acrylonitrile, onto cotton cellulose was studied using uranyl nitrate and ceric ammonium nitrate as photoinitiators. uranyl nitrate photoinitiation showed a higher level of grafting for styrene, whereas in the case of acrylonitrile ceric ammonium nitrate was found to..

characterization of smoke from smoldering combustion for the evaluation of light scattering type smoke detector response

experiments were performed to characterize smoke produced from smoldering materials using light scattering theory. a prototype scattered light detection instrument (sldi) was developed to measure the intensity of light scattered at various angles by smoke particles. a gallium arsenide solid-state laser was used as the source, with photodi..

comparison of multispectral video and spot-1 hrv observations for cotton affected by soil salinity

a 15-ha field of cotton (gossypium hirsutum l.) with an erratic pattern of soil salinity was overflown twice during the 1989 growing season with each of two sensor systems, a multispectral videography system and the high resolution visible (hrv) scanner of the french polar-orbiting satellite spot. the objectives were to compare the respon..
