Background Fractional Flow Reserve (FFR) is an invasively determined index of the functional severity of an intermediate coronary stenosis by measuring the pressure drop across the lesion [1]. Noninvasive pressure gradient (ΔP) measurements using phase-contrast (PC)-MRI have been attempted in the aorta, carotid, and renal arteries [2-4]. The purpose of this study is to assess the reproducibilit...
During high-frequency oscillatory ventilation (HFOV), a situation may occur where the mean alveolar pressure (mPalv) differs significantly from airway (mPaw). Studies documenting differences between these pressures during HFOV have documented states of both higher and lower mPalv compared to mPaw. The effect parameters on difference is not yet understood. aim this study investigate how phenomen...
Induced subgraphs of Johnson graphs (JIS for short) were studied first time in 2010 by R. Naimi and Jaffrey Shaw [3]. They proposed a conjecture “ The graph Δp is JIS if and only if p is odd ”. We have attacked this conjecture and have been able to prove that If p is odd then Δp is JIS. Furthermore, we have characterize all graphs of order less than 6 and of size less than 7 into JIS and Non-JI...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
abstract abstract of thesis (includes summary, goals, execution methods, and results) story “al-obnosat al-bayza” is one of the short stories from “hanna mineh” collection. this story is a selection of lives of some humans during a voyage together, each of them is a symbol of human nature (love, mind, kindness) and examine social, cultural, and political aspects of governing system, and it...
esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
Background Fractional flow reserve (FFR) is an invasive diagnostic tool to evaluate the functional significance of an intermediate coronary stenosis by quantifying the pressure gradient (ΔP) across that stenosis [1]. Noninvasive ΔP measurement (ΔPMR) using phase-contrast (PC)-MRI in conjunction with Navier-Stokes (NS) equations has been attempted in large to medium size vessels [2-4], and recen...
Ventilator settings resulting in decreased driving pressure (ΔP) are positively associated with survival. How to further foster the potential beneficial mediator effect of a reduced ΔP? One possibility is promoting the active modification of the lung's "mechanical scenario" by means of lung recruitment and positive end-expiratory pressure selection. By taking into account the individual distrib...
