The effect of soluble fluorine species in different concentrations on the catabolic activity of Desulfotomaculum ruminis bacteria has been studied. The fluoride concentrations tolerated by and toxic to the bacteria have been determined. The degree of fluorine species toxicity was found to depend on the form in which fluorine is introduced into the medium and increases in the following order: Na...
introduction: soil erosion by water is one of the most important processes of land degradation, especially in semi-arid areas. among different types of the soil erosion, gully erosion accounts as one of the most critical processes which can cause soil destruction, changes in landscape and water resources filling of reservoir of dams,decrease in water transport capacity of rivers and agricultura...
Eighteen spring-born Columbia ram, wether, and zeranol-implanted ram lambs were examined to determine the influence of castration or zeranol implantation on collagen characteristics of skin, fell, and epimysium and possible relationships between collagen properties of each tissue and difficulty of pelt removal. Pelt removal force was lower in wethers than in rams (P < .05) and intermediate for ...
A total of 104 coagulase negative staphylococci, belonging to S. capitis, S. hominis, S. haemolyticus and S. warneri, originating from the collection of the Department of Pharmaceutical Microbiology (ZMF), Medical University of Lodz, Poland, were tested for their synergistic hemolytic activity. 83% of strains produced δ-hemolysin, however, the percentage of positive strains of S. haemolyticus, ...
Hydraulic conductivity in response to exchangeable sodium percentage and solution salt concentration
LFYgene plays important roles in determining plant flowering mainly by controlling the timing of phase transition. Constitutive under-expression of LFY gene in Arabidopsis resulted in the formation of late flowering and highly branching phenotype. In this paper, we investigated some physiological and biochemical properties of the transformantsthat were down-regulated LFY gene expression to dela...
This study aimed to investigate the irrigation water quality, major pollution sources, and human health hazards by focusing on heavy metal concentrations in surface of Han River watershed, South Korea that supplies for consumption irrigation. Here, Mn was found have highest mean concentration, with maximum concentration recorded at IH-2. The were higher during summer fall than spring. metals re...
1. Strontium absorption was studied in vivo with loops of ileum in rachitic chicks and found to be increased by vitamin D(3), bile salts and sodium lauryl sulphate. 2. Bile salts and sodium lauryl sulphate rendered strontium soluble in butanol-benzene (1:1, v/v). 3. Bile was not concerned in the absorption of iron in rats from its water-soluble form, ferrous sulphate. 4. Ligation of the bile du...
to investigate the effects of sowing date on yield and quality of six forage maize cultivars in rasht region, a field study was conducted in 2010. the experimental design was a randomized complete block using a factorial arrangement with three replications. treatments consisted of four levels of sowing date (22 may, 3, 15 and 25 june), and six maize cultivars (sc 260, dc 370, sc 500, sc 647, sc...
