The variance-covariance method is employed at low doses and in radiation fields of low dose rates from an 241Am (4 nGy/s) and a 90Sr (300 nGy/s) source. The preliminary applications and results illustrate some of the potential of the method, and show that the dose average of lineal energy or energy imparted can be determined over a wide range of doses and dose rates. The dose averages obtained ...
طی یک مطالعه آماری از نوع prevalence cross sectional study تعداد 178 نفر زن و مرد 44- 35 ساله و 150 نفر زن و مرد بالای 64 ساله مورد ارزیابی قرار گرفتند. نتایج حاصله بطور خلاصه عبارتند از: 1- میانگین DMFT در گروه سنی 44- 35 ساله برابر (15.4±7.3) بوده در حالیکه در گروه سنی 90- 65 ساله (5.7 ± 29.01) بوده است که در این مطالعه اختلاف معنی‌دار بوده است.(P<0.001) 2- در این تحقیق میانگین پوسیدگی با سن ...
Abstract Background and Aims Whether early eGFR declines (eGFR below age-expected values) in younger adults are associated with adverse outcomes is unknown. We aim to estimate the association of an decline by age group (18-39, 40-49, 50-65 years). Methods included 8.9 million (aged 18-65) ≥1 value using linked healthcare datasets Ontario from January 2008-March 2020. The categories &lt;60 &...
CONTEXT Case series demonstrate that bariatric surgery can be performed with a low rate of perioperative mortality (0.5%), but the rate among high-risk patients and the community at large is unknown. OBJECTIVES To evaluate the risk of early mortality among Medicare beneficiaries and to determine the relative risk of death among older patients. DESIGN Retrospective cohort study. SETTING AN...
In this paper, we characterise the compromise value of a game as the barycentre of the edges of its core cover. For this, we introduce the τ∗ value, which extends the adjusted proportional rule for bankruptcy situations and coincides with the compromise value on a large class of games.
the aim of the present study was to investigate the effect of two aerobic training programs with different intensities on some cardiovascular risk factors in young girls. for this purpose, 42 girls (mean age 20.59±1.46 years, height 160.29±4.75 cm, weight 59.23±8.82 kg, bmi 22.08±3.41 kg/m2, %bf 15.42±3.85 and vo2max 25.34±3.96 ml/kg/min) were voluntarily participated in this study and divided ...

هدف از این مقاله، بررسی اثر اضافه‌شدن کانال میانی در فرایند اکستروژن در کانال‌های هم مقطع زاویه‌دار (ECAP) بر‌روی خواص مکانیکی و ریزساختار مس خالص است. به این منظور، سه قالب با زوایای داخلی 65، 75 و 90 درجه طراحی و ساخته شد و نمونه های مسی درون تمامی این قالب ها طی 4 پاس اکستروژن مورد بررسی قرار گرفتند. نتایج حاصل از بررسی ریز ساختار مس نشان داد که با افزایش تعداد پاس اکستروژن، ساختار فلز مس در...
BACKGROUND To understand the influence of age on treatment and outcomes, we analyzed the largest group of patients 75 years or older with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PPCI) in a clinical trial. METHODS We analyzed data from 5745 patients in the Assessment of Pexelizumab in Acute Myocardial Infarction trial from July 13, 20...
