enhanced pesticide metabolism, a previously unreported effect of dietary fibre in mammals. / reprint: enhanced pesticide metabolism, a previously unreported effect of dietary fibre in mammals

the effects of various dietary fibers on the metabolism of the organochlorine insecticide, lindane, were compared. groups of six weanling female sprague-dawley rats were fed either a synthetic low-residue diet (lrd), lrd + 10 pectin, lrd + 10 agar, lrd + 10 cellulose, or purina lab chow for 28 days. the animals were then dosed orally with..

quantitative analysis of defects in silicon. silicon sheet growth development for the large area silicon sheet task of the low cost solar array project. quarterly progress report no. 1

the objective of this program is to evaluate and, if possible, predict the conversion efficiency for a variety of silicon samples with differences in structural defects, such as grain boundaries, twin boundaries, precipitate particles, dislocations, etc. it is important to know the type of defect/defects, and the concentration at which su..

enzyme technology digest. an information exchange in enzyme technology. volume 5, number 1, march 1976

enzyme technology digest, an information exchange in enzyme technology, is issued three times a year. this issue includes a feature article on the utilization of agricultural wastes--the enzymatic hydrolysis of matrix polysaccharides. a meeting report on the symposium on chemistry and applications of coenzymes and coenzyme analogs is pres..

array automated assembly: phase 2. quarterly report for period ending march 31, 1978

surface topography of texturized solar cells was investigated. no significant differences were found between high output and low output cells with a common texturizing treatment. differences were found between high output and low output cells with a common texturizing treatment. differences were found associated with variation in the dama..

bibliography on fibers and composite materials 1972-1978,

this bibliography continues and updates previously issued reports by battelle's columbus laboratories information centers on fibers, fiber-reinforced composites, as well as laminate, particulate, and eutectic composite materials. no organic matrix composites or fibers are included. this edition includes 2367 literature references publishe..

surface finish from reflected laser light

the characteristics of reflectance patterns generated when a laser beam strikes a machined surface contain adequate information to determine the degree of surface finish. an extensive development endeavor has established equipment and procedures required to properly extract data from reflectance patterns to obtain a repeatable correlation..

cuprous oxide photovoltaic cells

cuprous oxide, with a band gap of 2.0 ev, is an attractive material for solar cells because of low cost and great availability. the current conversion efficiency is 1, but theoretical estimates are 13. for various schottky barriers, e.g., al/cu sub 2 o, it is proposed that the v/sub oc/ is limited by chemical conversion of the junctions t..

automated production of insulated footwear

the objective of the project was to establish the necessary production equipment requirements to set up a production facility to produce an expanded polyurethane pull-on type insulated boot and included the selection, evaluation, and design of equipment using standard process engineering practices and procedures. this report contains a bo..

factors affecting the deformation of tungsten (a literature survey)

background information relative to wrought tungsten forming was required in support of development studies. seven principal areas of tungsten metallurgy were of interest: fabrication methods, delamination, recrystallization, heat treatment, fracture characteristics, impurity effects, and surface treatments. pertinent information in metal ..

adaptation of ion beam technology to microfabrication of solid state devices and transducers

a number of areas were investigated to determine the potential uses of ion beam techniques in the construction of solid state devices and transducers and the packaging of implantable electronics for biomedical applications. the five areas investigated during the past year were: (1) diode-like devices fabricated on textured silicon; (2) a ..
