in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
Abstract Background: Human beings have always used plants to cure diseases. Recently, some researches have revealed that Thymbra spicata’s essential oils contains Carvacrol and Thymol both of these compounds have anti-bacterial effects. In this study, we aimed to investigate the anti-bacterial properties of the essential oil of Thymbra spicata a native plant of Ilam province. Materials and ...
Sulfur is an essential element for a variety of cellular constituents in all living organisms. In tRNA molecules, there are many sulfur-containing nucleosides, such as the derivatives of 2-thiouridine (s(2)U), 4-thiouridine (s(4)U), 2-thiocytidine (s(2)C), and 2-methylthioadenosine (ms(2)A). Earlier studies established the functions of these modifications for accurate and efficient translation,...
Uptake and translocation of cations play essential roles in plant nutrition, signal transduction, growth, and development. Among them, potassium (K+) and sodium (Na+) have been the focus of numerous physiological studies because K+ is an essential macronutrient and the most abundant inorganic cation in plant cells, whereas Na+ toxicity is a principal component of the deleterious effects associa...
Potassium (K(+)) is an essential macronutrient required for plant growth, development and high yield production of crops. Members of group I of the KT/HAK/KUP family of transporters, such as HAK5, are key components for K(+) acquisition by plant roots at low external K(+) concentrations. Certain abiotic stress conditions such as salinity or Cs(+)-polluted soils may jeopardize plant K(+) nutriti...
this study focuses on tracing the clearly defined elements of magic realism in toni morrison’s song of solomon as an illustrious african american example of the mode. magic realism is a fictional technique that combines fantasy with raw physical reality in a search for truth beyond that available from the surface of everyday life. toni morrison, as a distinguished african-american practitioner ...
Growth of five strains of sulfur-oxidizing bacteria Acidithiobacillus thiooxidans, including strain NB1-3, was inhibited completely by 50 microM of sodium tungstate (Na(2)WO(4)). When the cells of NB1-3 were incubated in 0.1 M beta-alanine-SO(4)(2-) buffer (pH 3.0) with 100 microM Na(2)WO(4) for 1 h, the amount of tungsten bound to the cells was 33 microg/mg protein. Approximately 10 times more...
tains more nitrogen than any other element. Fourth, nitrogen is a very dynamic element in the soil system. Its concentration is constantly changing, usually decreasing. The other essential elements are significantly more stable in soils. Nitrogen, therefore, must be routinely added to turfgrass to maintain a soil level sufficient for turfgrass growth. An ideal nitrogen fertilization maintenance...
The plant hormone abscisic acid (ABA) regulates many essential processes in growth and development. The recent characterization of ABA-sensitivity mutations in RNA-binding proteins has led to the recognition of a functional link between post-transcriptional mRNA processing and the ABA signal transduction machinery. By influencing transcript abundance, these RNA-binding proteins may modulate ABA...
