AmI is a new information paradigm where people are empowered through a digital environment that is “aware” of their presence and context and is sensitive, adaptive and responsive to their needs. In this paper, we describe the intelligent Classroom (iClass) which aims to realize the AmI vision in Education in universities and schools. We will describe the architecture employed to build the iClass and we will present three different directions including the utilization of RFID technology, interacting with the user via speech and developing intelligent agents to learn the user behavior and adapt to its change over short and long time intervals.

The present report summarizes the experience of a tertiary care center in the present Lebanese war. Between 1975 and 1986, approximately 30,000 war casualties were treated at the American University of Beirut Medical Center (AUBMC). A disaster plan was implemented whenever more than 25 major trauma victims were received within 1 hour. In-field stabilization and emergency room (ER) thoracotomy were not employed. The results are illustrated by an analysis of 1,500 cases of abdominal trauma, (1,314 high-velocity gunshot wounds, 29 stab wounds, 157 blunt injuries). A total of 1,420 patients were operated on within 6 hours of admission and 711 within the first hour. Overall mortality was 130, 8.7%; 9.5% for gunshot wounds, 3.4% for stab wounds, and 2.5% for blunt trauma. One hundred forty-five patients or 9.7% had negative findings at laparotomy. The factors affecting mortality were hypotension on admission (26.5% for a BP less than 90 mm Hg and 2.8% for a BP higher than 90 mm Hg) and the presence of extra-abdominal injuries (14.4% with and 4.4% without). The chief causes of death were hemorrhage (3.7%), sepsis (2.1%), and ARDS (1.2%).

To identify fetal and maternal factors that might influence bone turnover, we prospectively studied 50 infants (30 preterm and 20 full-term) born at Ain Shams University Obstetric Hospital in Cairo, Egypt. Maternal parity and medical history and infant's weight, gestational age, gender and anthropometrical measurements were recorded. Cord blood samples were collected and serum type I collagen Cterminal propeptide (PICP) was assessed as a marker for fetal bone formation. First morning urine samples were collected and pyridinoline cross-links of collagen (Pyd) were measured as an index for bone resorption. Serum PICP was higher in premature infants when compared with full-term infants (73.30 Ϯ 15.1 versus 64.3 Ϯ 14.7, p ϭ 0.022) and was higher in male premature infants when compared with females (81.64 Ϯ 9.06 versus 66.0 Ϯ 15.7, p ϭ 0.018). In a multiple regression model using PICP as the dependent variable and controlling for different infant and maternal conditions, PICP significantly correlated with infant gender (r ϭ 8.26 Ϯ 4.1, p ϭ 0.05) maternal parity (r ϭ Ϫ2.106 Ϯ 0.99, p ϭ 0.041) and diabetes (r ϭ 22.488 Ϯ 8.73, p ϭ 0.041). Urine Pyd tended to increase in premature infants (612 Ϯ 308 versus 434 Ϯ 146, p ϭ 0.057) and correlated significantly with gestational age (r ϭ Ϫ63.93 Ϯ 19.55, p ϭ 0.002). Therefore, bone formation (PICP) is influenced by fetal age and gender, as well as maternal parity and diabetes. Bone resorption (Pyd) is mostly dependent on gestational age only. Further in-depth studies are needed to enrich management of this vulnerable population.

Premature infants have shown favorable outcomes in response to massage and physical activity. Whether such intervention can stimulate bone formation or decrease bone resorption is yet to be determined.

In this article, we explore the concept of an elastic &# x201C; HPC as a Cloud&# x201D; abstraction, the software infrastructure needed to support such an abstraction, and how scientific applications can use it. We have developed a prototype framework that transforms the Blue Gene/P system into an elastic Cloud. This framework ...

The synthetic antioxidants used were butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), propyl gallate (PG) and tertiary-butyhydroquinone (TBHQ). Other antioxidants such as ascorbyl palmitate (AP), mixed tocopherols (TOCO) and monoacylglycerol citrate (MGC) were also employed. The effectiveness of these antioxidants and their combinations was assessed using the Rancimat test by measuring the induction period for the oxidation of sunflower oil after heating at 180C for 1 h and comparing it to the oxidation kinetics of the oil without added antioxidants. All antioxidants and their binary or ternary mixtures showed different degrees of thermal instability. TBHQ individually, among all the examined antioxidants, showed the highest thermal stability. On the other hand, AP as an antioxidant in sunflower oil exhibited low stability during heating. The thermal stability of AP could be enhanced by the addtion of BHA or BHT in binary mixtures at a ratio of 1:3 (w/w). In addition, the ternary mixture of AP, TOCO and MGC (65:25:10) in sunflower oil also showed a higher stability to thermal inactivation. However, the ternary mixture containing 0.13% AP, 0.05% TBHQ and 0.02% MGC provided the optimal protection during thermal treatment. Although a combination of 0.13% BHT, 0.05% AP and 0.02% MG was very effective synergistically at room temperature, it showed a higher susceptibility to thermal inactivation. It was
