uptake, accumulation, and translocation of arsenical compounds by cotton

cotton plants grown in solution culture were exposed to arsenic trioxide (as//2o//3) from 0 to 8 $mu$ g as ml** $minus$ **1. arsenic was readily taken up by the roots but was not translocated to the shoots. in contrast, when carcodylic acid was applied in the range of 0-40 $mu$ g as ml** $minus$ **1, as was found not only in the roots but..

on the abnormally wide domain boundary in a polyaxial ferromagnet

a model is proposed for the domain boundary between cotton domains in a polyaxial ferromagnetic plate in which the magnetic flux inside a specimen is closed and there is a faraday magnetic phase in that domain boundary. the model provides a qualitative explanation of the abnormally wide domain boundaries observed on planar specimens of cu..

on the structure of cobalt garnet, a new synthetic silicate containing 8-coordinated cobalt(ii)

the x-ray structure of the coo//8 unit in cobalt garnet, a new synthetic silicate of the composition co//3al//2si//3o//1//2, is presented. the unit can be taken as a deformed cube, but its central co**i**i is more regularly 8-coordinated than that in $left bracket$ co(no//3)//4 $right bracket$ **2** $minus$ studied formerly by bergman and..

modelling of the human vasomotor control system and its application to the investigation of arterial disease

a control systems approach has been made to the investigation of the peripheral vasomotor control system. the thermal vasomotor control of digital bloodflow has been investigated in 46 subjects fourteen were controls, 26 were suffering from raynaud's phenomenon and the rest had suspected malfunctions of the sympathetic nervous system. to ..

dielectric constant of cotton

a technology derived from the technique for measuring magnetic susceptibility is applied to determine the average dielectric constant of cotton fibers. to a large extent the dielectric constant measurements are independent of the packing fraction and are reasonably independent of the shape of teh sample. the results obtained at a frequenc..

nutritional and toxicological evaluation of hibiscus sabdariffa oil and cleome viscosa oil

mesta seed oil (hibiscus sabdariffa), like cottonseed oil, contains cyclopropenoid fatty acids (2. 9) and epoxy fatty acids (2 6) in addition to normal fatty acids found in vegetable oils cleome viscosa (capparidaceae) seed oil is rich in linoleic acid (70) and free from any abnormal chemical constituents. nutritional and toxicological ev..

experimental study of the linear magnetic birefringence in erbium iron garnet

linear magnetic birefringence (cotton-mouton effect) and optical axis position have been measured in er//3fe//5o//1//2 crystals in the voigt geometry in the 10 - 300 k temperature range deviation of the optical axis away from the magnetic field direction is found below the compensation temperature, when the magnetic field is not applied a..

technical and economic assessment of charcoal and densified fuel from water hyacinths and cotton stalks

a study is presented on the production of charcoal and densified fuel using water hyacinths and cotton stalks as a feedstock. both biomasses have no economic value and occur in fairly high concentrations. the circumstances of the town of kosti in the sudan are specifically investigated. 23 refs

some experiments on detergency in aqueous and non-aqueous media - 13. builder effects in hard water versus builder effects in distilled water: single component formulations

in the reported experiments, the effect of different builders upon particulate soil removal and specific redeposition in distilled and hard water in the presence of a low concentration of anionic surfactant was studied, using six different soiled cotton fabrics, one soiled pe/cotton fabric, two different unsoiled cotton fabrics and two di..

enhanced cellulase production in mutants of thermomonospora curvata

thermomonospora curvata, a thermophilic actinomycete, secretes multiple forms of endo- $beta$ , 1-4-glucanase (eg) when grown on a cellulose-mineral salts liquid medium. the eg activity (measured as carboxymethyl cellulose hydrolysis) was separated by ion exchange chromatography into three distinct components which differed in their kinet..
