data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
A genetic determinant of the phenotypic variance of the molecular weight of low density lipoprotein.
The molecular weight of monodisperse human plasma low densitylipoprotein has been measured in 69 individuals and found to vary over the range of 2.4 to 3.9 X 10-6. By contrast, the molecular weight of low density lipoprotein measured on two separate occasions for specific individuals shows a mean difference of 0.07 X 10-6 and a standard deviation of 0.08 X 10-6; hence low density lipoprotein di...
black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
A huge advance in our understanding on the relevance of phenotypic plasticity in evolutionary processes has taken place during the last decades. However, there are several specific topics in which the phenotypic plasticity framework has not been deeply considered. One of these topics is our current interpretation of trait repeatability, which is defined as the consistency of a trait over time (...
background and objective: shigella species belong to the family enterobacteriaceae, which cause dysentery with abdominal pain and tenesmus in human. our country is one of the endemic and occasional epidemic areas of the disease. in the present study, repetitive extragenic palindromic polymerase chain reaction (rep-pcr) technique that has high differentiation and specificity power compared to ph...
