nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
In the affine plane AG(2, q) the point (x, y) is incident with the line Y = mX + α if and only if α = −mx + y. Hence α is a root of R(T,m) of multiplicity k if and only if the line Y = mX + α is incident with k points of the set A. This observation allows one to look at a problem of the following type: Given a subset of points of the affine plane that has restricted intersection properties with...
Background & Objectives: Recognition of epidemiology of acute myocardial infraction (AMI) in every region could be a need for design the programs for prevention of AMI. In this study we assessed the epidemiology of changes in AMI from 2002-2006 in Birjand(east of Iran). Methods: All of the patients which hospitalized by AMI diagnosis from 2002-2006 years, included in this study. We compared ...
The present review describes the author's involvement and contributions to the development of the semiconductor laser and terahertz oscillators at his laboratory during the period between 1957 and now. The author cites records to show that the idea of a semiconductor laser was documented as a Japanese patent in April 1957 prior to those of G. Gould in 1957 and C.H. Townes in 1958. Terahertz osc...
Being a derivative of the famous IEEE 802.11 family of standards [1], which was originally targeted at indoor wireless communication, the IEEE 802.11p amendment for vehicular communication [2] still bears certain assumptions about the wireless channel which do not apply for vehicular scenarios. As IEEE standardization is finished, international harmonization of local standards is already on the...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
