comparative uptake of actinides by plants and rats from the shoreline of a radioactive pond

to compared the bioaccumulation of several actinide elements by plants and rats from a contaminated pond shoreline, concentrations of **2**3**3u, **2**3**8u, **2**4**1am, **2**4**4cm, and **2**3**9pu were measured radiochemically in shoreline sediment, emergent macrophytes, cotton rats and soil and fescue grass collected 3-5 m away from t..

fungal degradation of cotton cordages under outdoor weathering

the indian tropical climatological conditions are ideal for generating optimum fungal activity and all types of service stores made from cotton have been found to suffer fungal attack resulting in their unserviceability and loss of materials. under tropical conditions the fungal degradation in cotton cordages is both intensive and extensi..

separation of seed by-products by an ac electric field

a method for separating constituents of the by-products derived from agricultural processes offers the possibility of recovering their valuable components. partial sorting by a unique electric field enriches the protein concentration in sunflower-seed meal and cottonseed meal by removing objectionable components such as hulls or gossypol...

response of cotton water stress indicators to soil salinity

a field study was conducted on cotton (gossypium hirsutum l c. v. acala sj-2) to investigate the effects of soil salinity on the responses of stress indices derived from canopy temperature, leaf diffusion resistance and leaf water potential. the four salinity treatments used in this study were obtained by mixtures of aqueduct and well wat..

automatic fruit pressure tester

an electrically driven fruit pressure tester with rack and pinion drive was interfaced to an automatic recorder. the device provides the fruit industry with a firmness tester that saves about 55 labor and minimizes operator variability errors when compared to hand-held equipment. 12 refs

disengagement of needle thread from rotating hook, effects of its timing on tightening tension, industrial single-needle lockstitch sewing machine

this paper aims to investigate experimentally the disengagement of needle thread from rotating hook in an industrial single-needle lockstitch sewing machine with respect to tightening tension. for this purpose, the disengagement of the thread from rotating hook was photographically observed, and the resultant changes in needle thread tens..

radiation-induced conductivity in foamed dielectrics

through observation of radiation-induced current transients which occur in foamed insulators (foamed silica, epoxy resin, and common cotton wool) when exposed to a pulse (40 ns) electron irradiation in vacuum and in air the authors show that hot electrons ( $less than$ 30ev) are responsible for a vacuum response while the conventional tra..

measurement of volumetric and linear shrinkage on black cotton soil

experimental investigations on the shrinkage of expansive black cotton soil have been made to study the process of shrinkage. tests have been conducted on compacted soil specimens with different water contents under controlled conditions of temperature and humidity. the changes that take place in the air and water phases of specimens have..

cleanroom wipers: a comparative study

an examination is made of several different forms of contamination that are associated with wiping materials. an outline is also given of some testing methods that can be used to determine the level of cleanliness of currently available wiping products. the best performers in the organic-residue test were found to be products made of abac..

wearing comfort of water absorbent acrylic fibers

the physical properties of water absorbent porous acrylic fibers related to wearing comfort, i. e. , water absorbency, drying, warmth retention, air permeability and frictional property have been compared with those of cotton and other fibers. an investigation has shown that, compared to regular acrylic fibers, modified water absorbent ac..
