The reaction of SeCl4 with the ubiquitous tert-butyl-substituted diazabutadiene ligand results in the isolation of a rare example of a 1,2,5-selenadiazolium cation, representing a novel route to Se-N ring formation; these heterocycles can be derivatised at selenium, which has led to the identification of a short Se...N secondary bonding interaction.

Abstract—Extracting and determining chlorophyll pigments (chlorophyll a and b) in green leaves are the procedures based on the solvent extraction of pigments in samples using N,Ndimethylformamide as the extractant. In this study, two species of soluble inorganic selenium forms, selenite (Se) and selenate (Se) at different concentrations were investigated on maize plants that were growing in nut...

Typical white muscle disease was produced within nine weeks in normal lambs fed pelleted, selenium-deficient meadow hay. Treatment with CSIRO 5% selenium pellets and grinders prevented the condition and provided adequate selenium for normal growth and health. All pellets were recovered at autopsy. Affected lambs given selenium pellets eventually recovered; in these, macroscopic lesions were bar...

Enshi is a high selenium (Se) region in Hubei, China, where human selenosis was observed between 1958 and 1963. This study investigated the daily dietary Se intake of residents in Shadi, a town located 72 km northeast of Enshi City, to assess the risk of human selenosis in the high Se area. Foods consumed typically by the local residents and their hair samples were analyzed for total Se concent...

Two experiments were conducted to study the effect of supplemental selenium at levels of 0, .1, .2, or .4 mg/kg to a finishing beef catt le diet containing .08 mg/kg. In one experiment, an increase (P<.05) in gain was obtained from adding .1 mg selenium per kilogram. However, in a second experiment, no benefit was obtained from adding .1 mg/kg and supplemental levels of either .2 or .4 mg/kg re...

The 4.6-hour Kr" period was reported by SnelP as a result of deuteron bombardment of krypton. The Kr" period was not obtained by Clancy' as a result of alpha-particle bombardment of selenium. In the latter bombardments, only a 114-minute krypton period, assigned to the excited level of stable Kr~, and a 33-hour krypton period, assigned to Kr ' ", were observed. The Kr'~ period was then consider...

An interaction between dietary cobalt and selenium was revealed when groups of female weanling rats were fed standard rations, containing different concentrations and ratios of the two trace elements, continuously over a 15 week period. It was found that the levels of selenium in the heart and skeletal muscle were positively related to dietary selenium and negatively related to dietary cobalt, ...

To determine the effects of maternal supranutritional selenium (Se) supplementation and maternal nutritional plane on offspring growth potential, ewes were randomly assigned to 1 of 6 treatments in a 2 × 3 factorial arrangement [dietary Se (adequate Se; 9.5 μg/kg body weight vs. high Se; 81.8 μg/kg body weight initiated at breeding) and plane of nutrition [60%, 100%, or 140% of requirements; in...

We investigate the mechanisms of the nonmetal-metal transitions of Se and Te induced by the volume compression both in the solid and liquid states by the density functional method. The volume compression increases the band width and the system transforms from nonmetal to metal phase both in the crystalline Se and Te. When the system has structural disorder, the energy of the anti-bonding level ...
