Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management, and data dissemination protocols have been specially designed for WSNs. The focus has been given to the routing protocols which might differ depending on the application and network architecture. In this(More)
IP Multimedia Subsystem (IMS) is very impor-tant due to the critical role it plays in the Next Generation Network (NGN) of the Fixed and Mobile Networks. Voice traffic in IMS will be served using Internet Protocol (IP) which is called Voice over IP (VoIP). This paper uses the "E-Model", (ITU-T G.107), as an optimization tool to select network and voice(More)
AIM To evaluate the accuracy of middle cerebral/umbilical artery resistance index (C/U RI) ratio in predicting acidemia and low Apgar score at 5 minutes after birth in the infants of women with preeclampsia. METHODS This prospective case-control study performed at Kasr El Aini University Hospital included 50 pregnant women with preeclampsia with or(More)
AIM To assess the effectiveness of low-dose aspirin in the prevention of preeclampsia and intrauterine growth restriction (IUGR) in high-risk pregnant women with abnormal findings at uterine artery Doppler velocimetry performed at 14-16 weeks. DESIGN Randomized controlled clinical trial. SETTING Department of Obstetrics and Gynecology, Faculty of(More)
Etodolac (ET) is a nonsteroidal anti-inflammatory drug with proved potential antitumor and uric acid lowering effects. It shows dissolution rate-dependent bioavailability. This work was carried out to improve the dissolution rate of etodolac using three carriers of known potential to improve solubility and hence dissolution rate of poorly soluble drugs(More)
In the present work the antiglaucoma drug, acetazolamide, was formulated as an ion induced nanoemulsion-based in situ gel for ocular delivery aiming a sustained drug release and an improved therapeutic efficacy. Different acetazolamide loaded nanoemulsion formulations were prepared using peanut oil, tween 80 and/or cremophor EL as surfactant in addition to(More)
Norgestrel, a synthetic progestin chemically derived from 19-nortestosterone, is six times more potent than progesterone, with variable binding affinity to various steroid receptors. The levonorgestrel-releasing intrauterine system (LNG IUS) provides a long-acting, highly effective, and reversible form of contraception, with a pearl index of 0.18 per 100(More)
Evaluating the IP Multimedia Subsystem (IMS) Performance is very important due to the critical role it plays in the Next Generation Network (NGN) of the Fixed and Mobile Networks. This paper proposes three robust and scalable methods that can be used to evaluate the performance, the Compliance of the IMS controllers and benchmark their different vendors.(More)
The ultimate goal of the BIM concept is to create a complete digital model of the building to insure the generation of an accurate bill of material and cost estimate along with coordinated drawings and details. This goal might need the contribution of various disciplines to provide the needed level of information. The development of capable specialized(More)
