The crystal structures of three new ternary compounds, NaCd0.92Sn1.08 (I), Na(Cd0.28Sn0.72)2 (II), and Na2CdSn5 (III) synthesized in a sodium-cadmium-tin system were determined by single-crystal X-ray analysis to be the following: (I) LiGeZn-type structure (hexagonal, = 4.9326(1) Å, c 10.8508(3) space group P-6m2); (II) CaIn2-type 4.8458(2) 7.7569(3) P63/mmc); isotype with tI-Na2ZnSn5 (tetragon...
FIG. 1. Effect of citrate ion concentration on the growth of Staphylococcus aureus, phage type 42D, at pH 7.2. Photo-nephelometer was nulled after the addition of 0.1 ml of an 18-hr (27 C) broth culture of staphylococci to 7.5 ml of broth. The left ordinate is a measure, expressed in arbitrary units of "nephelos," of the numbers of bacteria growing in the presence of five different concentratio...
High-temperature positron two-dimensional angular correlation of annihilation radiation ~2D-ACAR! measurements have recently been succesfully applied to map parts of the Fermi surface of YBa2Cu3O72d . Using the same principle, we have been able to observe with a bulk sensitive method, the Fermi surface of Nd22xCe xCuO42d . Although positron trapping by defects and correlation effects are strong...
Feeding beta-adrenergic agonists promotes muscle growth. Early histological techniques failed to show precisely how feeding ractopamine-HCl (Paylean) alters muscle growth in pigs. To understand these effects, an indirect enzyme-linked immunosorbent assay (ELISA) was used to determine the abundance of each adult skeletal muscle myosin heavy chain isoform, one means of assigning muscle fiber type...
The purpose of this study was to investigate the effects of diet supplemented with different levels of phytosterols (PS) on growth performance and lipid metabolism in broilers. A total of four hundred 1-day-old chicks (female: male =1:1) were randomly assigned into 4 treatments, each of which replicated 5 times with 20 chicks per replicate. Birds were fed with a basal diet without any additive ...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
the main purpose of the present study was to investigate the relationship between listening proficiency and metacognitive listening strategies awareness among low, mid, and highly self-regulated students. three hundred and seventy one efl students participated in this study (all grade 3 and 4 high-school students who were studying in khansar in academic year 1391-92). to gather the data, three ...
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Background Chromium (Cr) supplements used as “magic lift” without authentications and Cr contaminated sewage water cultivate vegetables and crops around the vicinity of big cities. It is scientific responsibility to find out the toxic effects and preventive measures against such pollutants by local cheapest sources. Testicular histopathology of hexavalent chromium (Cr+6) was investigated in adu...
