In circumstances such as in vitro fertilization (IVF) or in patients with luteal phase defect, one needs to ensure the establishment of pregnancy as soon as possible. At the same time, a question arises: How can a physician make sure that the β-hCG is of an endogenous source and not the residue of the prescribed drugs (hCG)? In this article we have studied the elimination time of 1M inject...

One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best solution. Since it is required to run the reservoir simulator hundreds of times, the process...

We present a real-time face tracker in this paper The system has achieved a rate of 30% frameshecond using an HP-9000 workstation with a framegrabber and a Canon VC-CI camera. It can track a person 'sface while the person moves freely (e.g., walks, jumps, sits down and stands up) in a room. Three types of models have been employed in developing the system. First, we present a stochastic model t...

This work demonstrates that excess hot-carrier currents in SO1 MOSFETs are caused by self-heating. Self-heating-free Ism data should be used for dynamic lifetime extrapolation due to long thermal time constant. The underlying mechanism, increased impact ionization with temperature at low drain bias, is studied experimentally from the angle of thermal activation energy. Our study indicates that ...

in this study, we aimed to investigate reproductive performance in estrus-induced zandi ewes treated with equine chorionic gonadotrophin (ecg) injection in combination with prostaglandin f2α (pgf2α)and gonadotrophin releasing hormone (gnrh) during non-breeding season. the estrous cycle was synchronized using controlled internal drug release (cidr) for 12 days. the ewes were randomly assigned to...

According to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injectio...

hemiscorpius lepturus is the most dangerous scorpion species, endemic in khuzestan province and other southwestern areas of iran, causing morbidity and mortality in children and adults. the efficacy of the antivenom for reversal of manifestation caused by venom of this scorpion is a controversial issue. in the present work, h. lepturus venom (1500 µg/kg) was subcutaneously injected into two ...

It is well known that a small fraction of positive ions can destabilize diocotron modes on electron plasmas. However, the historical (and recent) interpretation of experimental results in terms of 2D (or modified 2D) theories of ion-induced instabilities is apparently erroneous. Here, we experimentally characterize a strong exponential instability with no threshold, obtaining growth rates order...

Network-level emulation has recently been proposed as a method for the accurate detection of previously unknown polymorphic code injection attacks. In this paper, we extend network-level emulation along two lines. First, we present an improved execution behavior heuristic that enables the detection of a certain class of non-self-contained polymorphic shellcodes that are currently missed by exis...
