background: sick leave from work due to psychiatric disorders is a major public health problem, not only in japan but also worldwide. as males and females in japan tend to differ in their approach to work, a gender difference in perfectionism might be expected. we investigated the background factors leading to long-term absence from work due to sickness among psychiatric outpatients in japan . ...
two-dimensional electrophoresis (2-d electrophoresis) is a powerful and extensively used method for analysis of complex protein mixtures extracted from cells, tissue, or other biological samples such as helminth parasites including, f. hepatica. each spot on the resulting two-dimensional collection corresponds to a single protein species in the sample. this study was carried out to detect of gs...
“wild thorns” is a novel written by the palestinian novelist sahar khalifeh; it focuses on the colonisation of palestine from a feminist point of view. she considers the israeli colonisation as a patriarchy. this paper aims at investigating two types of colonization that have been represented in the form of patriarchy in the novel. the investigation of the issue of palestine from a feminist poi...
the aim of this paper is to introduce and study a new concept of strong double δ ( a ) σ -convergence sequences with respect to an orlicz function, and some properties of the resulting sequencespaces were also examined. in addition, we define the δ ( a ) σ -statistical convergence and establish someconnections between the spaces of strong double δ ( a ) σ -convergence sequences and the space of...
double-diffusive mixed convection in a lid-driven square enclosure filled with al2o3-water is numerically investigated. two-dimensional nonlinear governing equations are discretized using the control volume method and hybrid scheme. the equations are solved using simpler algorithm. the results are displayed in the form of streamlines, isotherms, and iso-concentrations when the richardson number...
myostatin or growth and differentiation factor 8 (gdf8), has been known as the factor causing double muscling phenotypes in which a series of mutations make the myostatin protein inactive, hence disabling it to regulate the deposition of muscle fibre. this phenotype happens with high frequency in a breed of sheep known as the texel. quantitative trait loci (qtl) studies show that a portion of t...
Let be a Banach algebra. Let be linear mappings on . First we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple Banach algebras, in certain case. Afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...
در این پایان نامه حل دستگاه معادلات خطی با استفاده از روش های تکراری دو گامی ایستا در حالت کلی و در حالتهای خاص بررسی می شود. همچنین خواص همگرایی این روشها برای ماتریس های نامنفی و نیمه معین مثبت (هرمیتی یا غیر هرمیتی) بررسی می شود. در ادامه روش jdsor (jocobi double sor) که یک روش تکراری دو مرحله ای می باشد را معرفی و خواص آن را بررسی می کنیم. در هر بخش با چند مثال عددی نتایج نظری بدست آمده را ...
A two stage process including a sintering under a cyclic loading is proposed as an alternative fabrication method of dense FeAl intermetallics from elemental powder mixtures. The first stage (pre-sintering) is conducted at two temperature values (620 °C and 670 °C, respectively) under a static and a cyclic loading with a frequency of 20, 40 and 60 Hz. The second one includes a pressureless sint...
