Our goal is to study the output process of a queue of which conditions the interdeparture time will preserve the IFR property. We found the interdeparture time doesn’t always preserve the IFR property even if the interarrival time and service time are both Erlang distributions with IFR. We give theoretic analysis and present numerical results of Em/Ek/1 queues. We show it by numerical examples ...
A fungal pathogen that killed adult Diaphorina citri Kuwayama (Asian citrus psyllid) (Hemiptera: Psyllidae) in Florida citrus groves during the fall of 2005 was identified and characterized. Investigation of this pathogen is important because D. citri vectors citrus greening disease (Huanglongbing), which was reported in Florida in 2005. The morphological and genetic data generated herein suppo...
چکیده اینترنت دارای کارکردهای مثبت و منفی و آشکار و پنهان است یعنی هم می تواند سازنده باشد و هم مخرب و هم می تواند نیت و هدف آشکار یا نهان داشته باشد و به عنوان یک فناوری برتر می تواند بر روی نسل جوان و خانواده ها تاثیر بگذارد لذا هدف اصلی این پژوهش ، بررسی میزان استفاده جوانان از اینترنت وتاثیر اینترنت بر روابط دانش آموزان با والدینشان می باشد.روش انتخاب شده برای این تحقیق پیمایش می باشد و ج...
Objectives The fractional flow reserve (FFR) is an index of the severity of coronary stenosis that has been clinically validated in several studies. The instantaneous wave-free ratio (iFR) and the resting distal coronary artery pressure/aortic pressure (Pd/Pa) are nonhyperemic pressure-derived indices of the severity of stenosis. This study sought to examine the diagnostic accuracy of the iFR a...
OBJECTIVES This study sought to compare fractional flow reserve (FFR) with the instantaneous wave-free ratio (iFR) in patients with coronary artery disease and also to determine whether the iFR is independent of hyperemia. BACKGROUND FFR is a validated index of coronary stenosis severity. FFR-guided percutaneous coronary intervention (PCI) improves clinical outcomes compared to angiographic g...
OBJECTIVES This study sought to examine the clinical performance of and theoretical basis for the instantaneous wave-free ratio (iFR) approximation to the fractional flow reserve (FFR). BACKGROUND Recent work has proposed iFR as a vasodilation-free alternative to FFR for making mechanical revascularization decisions. Its fundamental basis is the assumption that diastolic resting myocardial re...
This study investigates the effect of corporate governance mechanisms on Internet financial reporting (IFR) behavior. We rely upon agency theory to predict an association between the extent of a firm’s Internet disclosure behavior and its corporate governance structures. We measure corporate governance by shareholder rights, ownership structure, and board composition. We develop a disclosure in...
مسئله و هدف: خانواده اولین و بنیادیترین نهاد موجود در جامعه است که هم ضامن سلامت و هم بقای جامعه تلقی می گردد.اما خانواده همیشه قادر به نگهداشت انسجام و هدایت اعضاء به سمت یک هدف نیست و برخی از اوقات دچار گسست در بین اعضای خود می گردد که در نهایت این فاصله و گسست می تواند منجر به فروپاشی این نهاد بسیار مهم شود،در سالهای اخیر طلاق به مانند یک موریانه پایه های خانواده ایرانی را فروریخته و درهیچ ز...
The efficacy of topical, leaf residue, and soil drench applications with Isaria fumosorosea blastospores (Ifr strain 3581) was assessed for the management of the citrus root weevil, Diaprepes abbreviatus (L.). Blastospores of Ifr were applied topically at a rate of 10⁷ blastospores mL-1 on both the larvae and adults, and each insect stage was incubated in rearing cups with artificial diet at 25...
The IFR system is a RPC-based detector used to identify muons and neutral hadrons in the BaBar experiment at PEP II machine in SLAC. The RPC system can be used to reconstruct the trajectory of muons, pions and neutral hadrons interacting in the iron of the IFR. The different range and hit pattern allow to discriminate different particles crossing the IFR. An overview of the system design and th...
