high resolution planetary albedos - values and variability
the spectral variability of high-resolution planetary albedo is shown to be a useful tool in surface-type analysis. the possibility of using comparison between planetary albedos in selected wavelength regions for cirrus cloud identification has been investigated. the results of an analysis of digital data streams from the polar orbiter sa..
formulation of nondairy coffee whiteners with cottonseed protein isolates
nondairy coffee whiteners were prepared on a pilot scale using four different glandless cottonseed protein isolates prepared by different processes. bulk density, whitening capacity, cream separation and oil retention capacity of the whiteners were compared to those formulated with sodium caseinate and a commercial whitener glandless cott..
gossypol - high-performance liquid chromatographic analysis and stability in various solvents
an improved high performance liquid chromatography (hplc) method of gossypol analysis was developed and compared with the current spectrophotometric method. gossypol was determined in four samples of cottonseeds of gossypium birsutum with varying contents of gossypol, as well as in the stems and roots of g. arboreum and g thurber. the roo..
acidic hexane extraction of oilseeds: product quality
in the reported experiments, cottonseed was extracted with hexane and acidic hexane (hexane that contained 2-25 acetic acid) and properties of the resultant miscellae and meals were compared for each sample. pigment contents were only slightly larger in acidic hexane miscellae. settling rates of marc particles were much faster through aci..
hydrogenation of cyclopropenoid fatty acids occurring in cottonseed oil
in the reported experiments, the hydrogenation of cyclopropenoid acids and their relative reactivities during hydrogenation as compared to linoleic and oleic acids were examined nickel, palladium and platinum catalysts were used. the effect of temperature and type of catalyst were demonstrated in a series of hydrogenation experiments of s..
isolation of indole-3 carboxaldehyde from cotton plant parts
in the reported experiments, indole-3 carboxaldehyde was isolated from aqueous extracts of cotton plant parts by hplc. it was identified by its mass spectrum which was identical to that of an authentic sample of indole-3 carboxaldehyde. a mechanism to account for the mass spectral fragmentation pattern is proposed. 7 refs
surface-enhanced resonance raman scattering from water-soluble porphyrins adsorbed on a silver electrode
resonance raman (rr) and surface-enhanced resonance raman (serr) spectroscopy have been used to study two water-soluble porphyrins, tetrasodium meso-tetrakis(4-sulfonatophenyl) porphine(tspp) and meso-tetrakis(4-carboxyphenyl)porphine (tcpp) both compounds were found to adsorb spontaneously at a silver electrode and exhibit intense serr s..
mechanochemical process in cotton cellulose fiber
mechanical processing of cotton cellulose by means of a fiber cutter resulted in the disaggregation and defiberation of fiber bundles, shortening of fiber length, and loss of degree of polymerization. it is evident that the mechanical energy supplied by shear forces is sufficient to cause homolytic scission of cellulose main chains. mecha..
linear optical birefringence and dichroism measurement in liquids and colloidal dispersions
an apparatus is described for measuring the linear birefringence and linear dichroism induced in liquids or dispersions by an applied magnetic field. the apparatus uses a vibrating beam phase modulator and conventional optical and electro-optical components. it is capable of measuring $delta$ n $prime$ (the real part of the complex birefr..
magnetic birefringence of polystyrene sulphonate: molecular weight and concentration dependence
in the reported experiments, the specific cotton-mouton constant of water solutions of pss-na** $plus$ of different molecular weight have been measured at concentrations below 2 in the absence and presence of added salt. a bare persistence length q $equals$ 12 a is found from the high ionic-strength molecular weight and concentration inde..
