BACKGROUND Tobacco smoking is the main health-care problem in the world. Evaluation of scientific output in the field of tobacco use has been poorly explored in Middle Eastern Arab (MEA) countries to date, and there are few internationally published reports on research activity in tobacco use. The main objectives of this study were to analyse the research output originating from 13 MEA countrie...
Reduced antiplatelet effect of clopidogrel assessed with multiple electrode aggregometry (MEA) and vasodilator stimulated phosphoprotein-phosphorylation (VASP-P) assay has been proven to predict major adverse cardiovascular events (MACE) after coronary stenting. So far no consecutive registry has evaluated the usefulness of different adenosine diphosphate-based platelet function tests to predic...
Copulas are a general tool for assessing the dependence structure of random variables. Important properties as well as a number of examples are discussed, including Archimedean copulas and the Marshall-Olkin copula. As measures of the dependence we consider linear correlation, rank correlation, the coefficients of tail dependence and association. Copulas are a tool for modeling and capturing th...
BACKGROUND Microelectrode array (MEA) devices are frequently used in neural circuit studies, especially in retinal prosthesis. For a high throughput stimulation and recording paradigm, it is desirable to obtain the responses of multiple surface RGCs initiated from the electrical signals delivered to multiple photoreceptor cells. This can be achieved by an high density MEA-tissue-MEA (MTM) sandw...
H(+)-pumping ATPases were detected in microsomal vesicles of oat (Avena sativa L. var Lang) roots using [(14)C]methylamine distribution or quinacrine fluorescent quenching. Methylamine (MeA) accumulation into vesicles and quinacrine quench were specifically dependent on Mg,ATP. Both activities reflected formation of a proton gradient (DeltapH) (acid inside) as carbonyl cyanide m-chlorophenylhyd...
هدف اصلی این تحقیق بررسی شروع رشد مُد i تورق در کامپوزیت های لایه ای چند جهتی با ترک بین دو لایه صفر درجه است. به عبارت دیگر تاثیر لایه های دوردست محل تورق، بر توزیع نرخ رهایی انرژی کرنشی در پیشانی ترک و مقدار بار بحرانی نمونه تیر یک سرگیردار دولبه بررسی شده است. همچنین شرایط لازم برای تعیین چقرمگی شکست بین لایه ای تیر یک سر گیردار دولبه با چیدمان دلخواه، بر اساس معادل سازی آن با چیدمان تک جهته ...
This work provides new viscosity data of unloaded and partially carbonated aqueous monoethanolamine-piperazine (MEA-PZ) solutions at temperatures between 303.15 373.15 K a N2 pressure 400 kPa. In both cases, the MEA-PZ was measured three different concentrations PZ 5, 10, 15 wt % by keeping concentration MEA constant 30 %. For solutions, measurements were performed varying CO2 0.13 0.55 mol CO2...
their excellent safety profile, despite their low transgene expression efficiency in comparison to that of viral vectors. For their administration, cationic lipid-mediated transfer is a promising approach, because of its low toxicity, ease of preparation, and potential for active targeting. One disadvantage associated with the use of DNA–cationic lipid complexes systemically is the induction of...
در جوامع معمولی آماری، اغلب وضعیت توزیع عادی یا نرمال حاکم است و لذا در آنها استفاده از تابع چگالی احتمال گوسی یا نرمال و استفاده از میانگینگیری حسابی یا معمولی کار صحیحی میباشد. اما اگر جامعه آماری از تعدادی جهت دلخواه فضایی تشکیل شده باشد، وضعیت توزیع عادی یا نرمال حاکم نمیباشد. در این شرایط از تابع چگالی احتمال فیشر ومیانگینگیری برداری میتوان بهره برد. یکی از جوامع آماری جهتی، جامعه آما...
