Abstract: Objective: To review the outcome of prostaglandin induction of labor in term pregnant women with previous one ce-sarean section compared to those without previous Cesarean section. Design: 18 years retrospective review of hospital records and case note review of index cases. Setting: University hospital. Population: Three hundred and twenty two women who had their labor induced with prostaglandin E2. One hundred and sixty one women had one previous Ce-sarean section. Methods: This study was conducted at King Fahad University Hospital, University of Dammam. It is a tertiary referral center with approximately 2300 births per year. We searched the hospital's records of deliveries from January 1992 to December 2009 and reviewed all indications and outcomes of prostaglandin induction of labor in women with one previous Cesarean section. The control group was composed of women who had their labor induced with prostaglandin but without previous Cesarean section. Main outcome measures: Labor outcome and uterine rup-ture Results: Three hundred and twenty two women were included. All received prostaglandin E2 for induction of labor. One hundred and sixty one women had one previous Cesarean section (study group) and the rest had no previous Ce-sarean section (control group). There was no difference in the rate of vaginal delivery between study and control group, 68.3% and 79.5% (p value 0.3), respectively. The rate of uterine rupture was 30 times higher in study group (2.5% Vs 0.033%). Conclusion: In women with one previous Cesarean section, induction of labor with prostaglandin leads to comparable rate of vaginal delivery similar to those without prior Cesarean section but with relatively high risk of uter-ine rupture.

Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.37077
Abstract: From 2007-2009, National Energy and Water Research Center (NEWRC) on behalf of Abu Dhabi Water and Electricity Authority (ADWEA) conducted a long term baseline study of nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), ozone (O3) and particulate matter <10 μm in diameter (PM10) using ambient air quality station located in the vicinity of Al Mirfa power plant in Abu Dhabi, United Arab Emirates (UAE).The objective of this study was to establish baseline levels and study the behavior of airborne pollutants from natural as well as anthropogenic origins with temporal variations. The study reveals that the average hourly values for NO2, SO2, and 8 hour average of CO were within the acceptable levels of 400, 300 and 30,000 μg/m3 respectively, whereas the levels of O3 as 8 hour average (<200 μg/Nm3) and PM10 (<150 μg/Nm3) occasionally exceeded the FEA permissible limits during the study period. Seasonal variation based on three years data reveals that the highest concentration of NO2 and SO2 were during winter and for CO and O3 during summer months. Results indicate that the levels of SO2 and CO were significantly controlled and improved while the fuel combustion of Al Mirfa power plant had increased from 2007 to 2009. Dust has significantly impact on the air quality by elevated levels of PM10 exceed in several instances associated with regional sand- storm during the monitoring period.

Journal of Signal and Information Processing (JSIP) , 2017, DOI: 10.4236/jsip.2017.81001
Abstract: Encryption and decryption method of three-dimensional objects uses holograms computer-generated and suggests encoding stage. Information obtained amplitude and phase of a three-dimensional object using mathematically stage transforms overlap stored on a digital computer. Different three-dimensional images restore and develop the system for the expansion of the three-dimensional scenes and camera movement parameters. This article talks about these kinds of digital image processing algorithms as the reconstruction of three-dimensional model of the scene. In the present state, many such algorithms need to be improved in this paper proposing one of the options to improve the accuracy of such reconstruction.

Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2011, DOI: 10.4236/jcdsa.2011.12007
Abstract: Professor Syed Ghulam Shabbir (1923-2002), is one of the Pakistani well-known dermatologists. In 1986, Shabbir and his colleagues described a novel autosomal recessive syndrome, which they called laryngoonychocutaneous syndrome. They reported this condition, in 22 patients in 12 families living in Lahore, Pakistan. This syndrome is characterized by cutaneous erosions, nail dystrophy and exuberant vascular granulation tissue in certain epithelia, especially conjunctiva and larynx. This report sheds light on Shabbir and the syndrome that bears his name.

Rami Al-Ruzouq, Samih Al Rawashdeh
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.62014
Abstract:

Mining activities often cause dramatic changes in landscapes, particularly in the dump sites and its surrounding environment. Land rehabilitation is the process of renovating damaged land to some extent of its original shape and aims to minimize and mitigate the environmental effects to allow new land uses. The success of different rehabilitation strategy and newly suggested urban and architecture modeling depends on the landscape characterization (topography of the study area and its derivatives such as slope and aspects, geological and geomorphologic nature of the study area). The aim of this study is to demonstrate the utility of different methodologies based on geomatics techniques (Photogrammetry, Remote Sensing, Global Positioning System (GPS) and three dimensional Geographic Information System (GIS)) for highlighting landscape characterization which is needed for rehabilitation of Mahis area. Photogrammetric adjustment procedures were used to create digital elevation model and Orth-Photo model for the study area using aerial images. Remote sensing data were used for land classification to provide vital information for rehabilitation planning. GPS field observations were used to build spatial network for the study area based on ground control point collections. Finally, realistic representation of the study area with three dimensional GIS was prepared for the study area considering ease and flexible updating of the geo-spatial database.

Open Journal of Therapy and Rehabilitation (OJTR) , 2016, DOI: 10.4236/ojtr.2016.43015
Abstract: Existing literature indicates that a weight-management program that includes diet modification, Physical Activity (PA) instructions and behavioral modification in weight reduction increases obese adolescents’ participation in PA. However, the effect of such a program on obese Saudi adolescents is unknown. Objective: To examine the effects of a weight-management program in terms of decreasing Body Mass Index (BMI) and improving participation in PA in obese Saudi adolescents, and to establish whether differences exist between genders in response to a weight-management program. PA was measured by Arab Teens Life Style (ATLS) questionnaire for both groups. Results: A wide range of differences in PA and sedentary time are evident between new and weight- managed patients and two genders. PA performance was significantly higher among the weight- managed patients compared with new patients. Also, for boys there were no differences between both groups in PA performance. While, girls’ PA was significantly higher among the girls in weight- managed group compared with girls in new patients group. Weight-managed patients spend significantly less time on the computer and/or the Internet per day compared with new patients. After treatment, the mean BMI among the weight-managed patients slightly decreased. Conclusion: The study findings suggest that the weight-management program could be effective in treating Saudi obese adolescents due to its effect in BMI reduction and greater improvement in PA performance. The surprising result from this study, PA differences between the groups were because of the total PA of girls only, meaning that obesity treatment program can lower the percentage of obesity among women and increase their levels of physical activity.

Wael Al-Aghawani, Isam AL Naser
Pharmacology & Pharmacy (PP) , 2019, DOI: 10.4236/pp.2019.105019
Abstract:
Salvia officinalis has been commonly used in Syria and other Middle East countries in popular medicine for many medical purposes. One of the strong claims about its properties is the spasmolytic effect. The aim of this research was to investigate the spasmolytic effect of ethanolic extract of Salvia officinalis in isolated rabbit ileum preparations. Male rabbits were sacrificed and portions of ileum were isolated and mounted in Tyrode’s solution. Afterwards, the experiments were performed according to different groups with different spasmogenic agents: the first group was only with spontaneous contraction, the second was KCl-induced contractions and the third was Carbachol-induced contractions. The examined extract was added cumulatively in all previous groups. Verapamil was used as a reference. The results showed profound relaxing effect of S. officinalis extract in mentioned groups, especially in the group of KCl-induced contraction. These findings suggest that the main mechanism of the spasmolytic action is related to the

Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.29099
Abstract: Due climatic variability and anthropogenic changes, floods have been raised lately in several regions worldwide. The resulting impact from floods is often harmful. This can be applied to Saudi Arabia, the country which is known by dry climatic conditions, and it became lately a typical region for such natural hazard. Hence, floods are observed as a yearly disaster with high magnitude of influence. Jeddah, a coastal Saudi city on the Red Sea to the west, has witnessed severe event in November 2009, when flooded water and sediments (torrents) invaded the urban areas and resulted decease of many people and destroyed the infrastructure and civilized zones. The lack of mitigation implements exacerbated the problem. This study implies an assessment of flood hazard risk in Jeddah region. It aims to identify the zones subjected to flood and then inducing the influencing factors at different levels of effect. For this purpose space techniques were utilized, with a focus on IKONOS satellite images, which are characterized by high resolution in identifying terrain features. In addition Geographic Information System (GIS) was also used to support space techniques. Thus, damaged areas and the mechanism of flooding process were recognized. This helps avoiding further urban expansion in areas under flood risk and will aid decision maker to put new strategies for hazard management.
Low Temperature Gas Sensing Coatings Made Through Wet Chemical Deposition of Niobium Doped Titanium Oxide Colloid  [PDF]
Naji Al Dahoudi
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.24034
Abstract: Niobium doped titanium oxide (TiO2) colloid was synthesized to fabricate a hydrogen gas sensor layer on oxidized silicon wafer substrate. The layers were obtained using spin coating technique and then heated in air at 500°C for 30 min. The doping of TiO2 led to a significant enhancement of the sensitivity of the layer especially at low operating temperature. The effect of doping was found effective of operating the sensor at relatively low temperature (150°C). The layers show a very smooth nanostructure with average roughness of less than 0.5 nm. The behavior of the sensing characteristics of such layers was discussed related to their chemical compositions, morphology and their crystalline structure. The morphological and structural characteristics of the layers were studied through X-ray diffraction (XRD) and Atomic force microscopy (AFM).
