osha regulations and risk assessments

the paper reviews the rational process by which occupational safety and health administration (osha) develops standards for the prevention of occupationally related illnesses. the hazards caused by lead, arsenic, cotton dust and coke oven emissions are discussed

diurnal variations of vegetation canopy structure

the leaf inclination-azimuth angle distribution is a major determinant of the electromagnetic response of vegetation canopies in field and modeling studies, researchers commonly assume that (i) leaf orientation can be described by two separate distributions of inclination and azimuth angles, (ii) the leaf inclination angle distribution of..

filament polyester: an international view

the interrelationship of cotton-crop land, population, climatic conditions and fiber economics suggests a resurgence in the use of filament polyester. it is believed that textured polyester will exhibit outstanding growth in developing countries during this decade, in its own right, and as a replacement for spun yarns in selected end-uses

antioxidant activity of amino acids in two vegetable oils

results of an experimental program are presented which show that of 27 amino acids studied, most had some antioxidant activity when added in aqueous solution to either safflower oil or a mixture of sunflower and cottonseed oil (active oxygen and storage methods) cysteine-hcl, glutamic acid-hcl (in the mixture), and glutamic acid-hcl (in s..

some experiments on detergency in aqueous and nonaqueous media - 15. influence of antiredeposition agents on the deposition of hydrophobic particulate soil on different textiles - 1

data are presented which show that the antideposition properties of antiredeposition agents depend not only on thier concentration and on the nature of the textile, but also on the particle size of the soil and on its degree of dispersion. it is found that the nonionic antiredeposition agents are more effective than cmc for preventing the..

some experiments on detergency in aqueous and non-aqueous media - 14. influence of chemical and mechanical wear of cotton on the deposition of hydrophobic particulate soil

data are presented which show that deposition of hydrophobic particulate soil on cotton fabric laundered 35 times and bleached by hypochlorite is proportional to the logarithm of the degree of polymerization. it follows that chemical wear decreases deposition this is attributed to the increase in the number of carboxyl end-groups when cel..

analytical method of ultra-trace tellurium for samples of sea- and environmental-water

a method is presented for the concentration of tellurium in sulfhydral cotton fiber. the mechanism of te-re catalytic polarographic behavior has been studied. the optimal conditions of systems are proposed. an analytical procedure of preconcentration with sulfhydral cotton fiber and catalytic polarographic determination of ultra-trace tel..

effect of silvicultural practices on wood quality of southern hardwoods

survey data are presented which reveal that the availability of quality natural southern hardwoods is increasing although still restricted. responses from fertilization, irrigation, and fertilization, pruning, and thinning are commonly obtained in improving tree growth and quality. hardwood plantations are being established at a rate of a..

chemical profiling of washed and mechanically cleaned cotton

in the reported experiments, cotton samples were analyzed after water washing or mechanical cleaning to compare the effects of such processes on chemical content of the bulk cotton. water extracts of the samples were analyzed for organic carbon content by measuring total organic carbon and for ionizable species by measuring conductance. t..
