mononuclear and binuclear cationic complexes of vanadium(ii)

even though severe difficulties with crystallographic disorder have made it impossible for the authors to obtain complete or accurate structures for $left bracket$ v//2cl//3(thf)//6 $right bracket$ $left bracket$ alcl//2r//2 $right bracket$ compounds, the presence of the dinuclear cation, very similar to that in $left bracket$ v//2cl//3(t..

flexible flat conductor for connection between an integrated circuit chip and printed circuit board

ic chips are conventionally mounted with their contact pads directly connected to the terminals on a ceramic or epoxy glass p/c board. as circuit-packaging applications require increasing packaging densities, the separation distance between adjacent ic chips on the p/c board decreases. when changes are necessary, it becomes difficult to m..

temperature fields in components of cotton ginning equipment in continuous laser treatment

three-dimensional and approximate systems of the heat conductivity equations are used to determine nonstationary temperature fields in a ring-shaped sheet and a strip in continuous laser treatment conditions. the specific power of radiation varied in accordance with the normal distribution law. the dependence of the temperature of the str..

computation of the discrete fourier transform on the cellular array processor

the cellular array processor is a single-instruction multiple data type of computer. one application is the evaluation of discrete fourier transforms using new algorithms that exploit the parallelism in the cellular array processor architecture. execution times are much shorter than for general-purpose array processors

helium and electron beam induced enhancement in adhesion of al, au and pt films on glass

30-1100 nm thick films of al, au and pt were deposited on glass substrates and bombarded with 2 mev he**2** $plus$ ions or 10 kev electrons. scotch tape, cotton bud abrasion and scratch tests were employed to measure adhesion changes, as a function of dose, dose rate, film thickness, method of film deposition, aging and thermal annealing ..

recovery of water-soluble solvents from oilseeds

water-soluble solvents such as ethanol and isopropanol are recovered from oilseeds in equipment similar to that used for recovering hexane, but the bases for design are considerably different. present and future commercial processes employing aqueous solvents are described, and desolventizing extracted particulates from them examined, par..

diurnal movements of cotton leaves expressed as thermodynamic work and entropy changes

three angles were measured per leaf to establish the solar induced trajectories for cotton leaves comprising both irrigated and unirrigated cotton canopies. these data and values for the solar coordinates were subsequently used to calculate changes in the angle $gamma$ between the normal to each leaf and the sun. these results indicate th..

uptake of nitrogen-15 by cotton under salt stress

evidence was gathered to evaluate the effect of salt stress on **1**5n absorption rate by plants, to indicate how plant parts (roots and shoots) react to nac1 stress conditions. nitrogen (**1**5nh//4) absorption studies were on cotton (gossypium hirsutum l. ) grown in complete hoagland nutrient solution in pots with various nac1 concentra..

hydraulic behaviour of perforated plates using water and solid material

general theories for pressure drop across a plate are given the hydraulic characteristics of a perforated plate when partially covered with solid material are investigated. tests were carried out initially with clean water and later with the addition of small pieces of cotton wool to simulate the effect of solids loading on the plate. the..

sorption of heavy metals with corncob hydroxylate-red onion skin resins

the disposal of organic wastes is becoming a serious problem, having arisen through rapid urbanization of an increased population and public awareness on the quality of the environment. recently, studies have been reported on the removal of toxic heavy metal ions from effluents by treating with various agricultural products such as tree b..
