some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
A 47-year-old woman with myasthenia gravis treated with azathioprine, prednisone, and plasmapheresis was admitted for respiratory failure following 2 weeks of fever with splenomegaly, jaundice, coagulopathy, and pancytopenia (white blood cells, 1.1 3 10/L with 64% neutrophils; hemoglobin, 9.5 g/dL; platelets, 79 3 10/L) but no substantial schistocytosis. Triglyceride (330 mg/dL) and ferritin (7...
The plant-specific NAC transcription factors play important roles in plant response to drought stress. Here, we have compared the expression levels of a subset of GmNAC genes in drought-tolerant DT51 and drought-sensitive MTD720 under both normal and drought stress conditions aimed at identifying correlation between GmNAC expression levels and drought tolerance degree, as well as potential GmNA...
in this paper we prove that each element of any regular baer ring is a sum of two units if no factor ring of r is isomorphic to z_2 and we characterize regular baer rings with unit sum numbers $omega$ and $infty$. then as an application, we discuss the unit sum number of some classes of group rings.
In this research, feasibility study of integrating thermal desalination unit with Gas Turbine (GT) has been investigated using retrofit and grass root design techniques for Lavan Island Oil Refinery which is located in Persian Gulf. According to computed parameters on developed code for the power generation unit No.1 using EES (Engineering Equation Solver) software, thermal efficiency of t...
ATCA H i and radio continuum observations of the peculiar southern galaxy IC 2554 and its surroundings reveal typical signatures of an interacting galaxy group. We detected a large H i cloud between IC 2554 and the elliptical galaxy NGC 3136B. The gas dynamics in IC 2554 itself, which is sometimes described as a colliding pair, are surprisingly regular, whereas NGC 3136B was not detected. The H...
