Flood Hazard Mapping of Lower Indus Basin Using Multi-Criteria Analysis  [PDF]
Saba Zehra, Sheeba Afsar
Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.44008
Abstract: Flooding has been one of the recurring occurred natural disasters that induce detrimental impacts on humans, property and environment. Frequent floods is a severe issue and a complex natural phenomenon in Pakistan with respect to population affected, environmental degradations, and socio-economic and property damages. The Super Flood, which hit Sindh in 2010, has turned out to be a wakeup call and has underlined the overwhelming challenge of natural calamities, as 2010 flood and the preceding flood in 2011 caused a huge loss to life, property and land use. These floods resulted in disruption of power, telecommunication, and water utilities in many districts of Pakistan, including 22 districts of Sindh. These floods call for risk assessment and hazard mapping of Lower Indus Basin flowing in the Sindh Province as such areas were also inundated in 2010 flood, which were not flooded in the past in this manner. This primary focus of this paper is the use of Multi-criteria Evaluation (MCE) methods in integration with the Geographical Information System (GIS) for the analysis of areas prone to flood. This research demonstrated how GIS tools can be used to produce map of flood vulnerable areas using MCE techniques. Slope, Aspect, Curvature, Soil, and Distance from Drainage, Land use, Precipitation, Flow Direction, and Flow Accumulation are taken as the causative factors for flooding in Lower Indus Basin. Analytical Hierarchy Process-AHP was used for the calculation of weights of all these factors. Finally, a flood hazard Map of Lower Indus Basin was generated which delineates the flood prone areas in the Sindh province along Indus River Basin that could be inundated by potential flooding in future. It is aimed that flood hazard mapping and risk assessment using open source geographic information system can serve as a handy tool for the development of land-use strategies so as to decrease the impact from flooding.
Determination Cadmium and Lead Pollution Resources of Ardabil Plain Underground Waters  [PDF]
Saba Hajjabbari, Ebrahim Fataei
Open Journal of Ecology (OJE) , 2016, DOI: 10.4236/oje.2016.69053
Abstract: Underground water is among the most important sources of drinking water. The aim of this study was to determine the concentrations of heavy metals (cadmium, lead) in providing plain of Ardabil in 2015. This study was cross-sectional, drinking water samples from 100 wells were prepared according to standard procedures. The dimensions of 350 × 350 meter grid station via a station in the network were determined by atomic absorption spectrometry AAS analysis of samples. The data obtained were analyzed using SPSS software. The average concentrations of lead, cadmium in groundwater wells in the area were also studied. The mean concentrations measured in the majority of groundwater wells in the plain of Ardabil lower than the allowed amount were designated according to a national standard.
Chaos Behavior and Estimation of the Unknown Parameters of Stochastic Lattice Gas for Prey-Predator Model with Pair-Approximation  [PDF]
Saba Mohammed Alwan
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.715148
Abstract: In this paper, the problem of chaos, stability and estimation of unknown parameters of the stochastic lattice gas for prey-predator model with pair-approximation is studied. The result shows that this dynamical system exhibits an oscillatory behavior of the population densities of prey and predator. Using Liapunov stability technique, the estimators of the unknown probabilities are derived, and also the updating rules for stability around its steady states are derived. Furthermore the feedback control law has been as non-linear functions of the population densities. Numerical simulation study is presented graphically.

Saba J. Al Heshemi
Open Journal of Obstetrics and Gynecology (OJOG) , 2017, DOI: 10.4236/ojog.2017.72028
Abstract: Background: Peripartum hysterectomy is the procedure of removing the uterus after vaginal delivery or cesarean birth; it remains a life-saving procedure in cases of severe uterine hemorrhage. Objective: To know the incidence of peripartum hysterectomy in Misan province, what is the main cause of this procedure, and if there is any change in the incidence of this procedure during a 3 year study period. Method: A descriptive cross sectional study was done in Misan province for all cases of peripartum hysterectomy during the period from 2014-2016. All information regarding present pregnancy, previous obstetric history, the cause of peripartum hysterectomy, any complications & infant outcome, were taken from the case sheet & from the patients themselves. 50 patients were enrolled in this study, and only 30 patients needed peripartum hysterectomy and 20 patients’ uterus were saved by repair surgery. Results: During the study period of 3 years, there was 72,720 deliveries, and during that time 30 peripartum hysterectomies were carried out of the 50 cases studied, which gave an incidence of 0.4/1000 deliveries. The patients were diagnosed as: rupture uterus in 30 (60%) cases, adherent placenta in 14 (28%) & 6 (12%) cases had atonic uterus. The major postoperative complication was anemia which complicated 23 (46%) cases, & then bladder injury 5 (10%). Admission to ICU was needed for 24 (48%) cases. There were 32 (64%) cases needed ≥4 units of blood transfusion. There were 38 (76%) cases stayed in hospital for ≥4 days. The most common cause for peripartum hysterectomy was for adherent placenta (28%) & rupture uterus (20%). Conclusion: The incidence of peripartum hysterectomy was 0.4/1000 (0.04%) deliveries. The most common reason behind peripartum hysterectomy was for adherent placenta and next was for uterine rupture. The rate of this procedure was not changed during the study period.
Students’ and Instructors’ Perceptions of Turnitin: A Plagiarism Deterrent?  [PDF]
Najwa Saba Ayon
Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.813141
Abstract: Academicians consider plagiarism a major threat to academia. To combat that threat, a lot of universities, including the researcher’s university, have been using Turnitin. It is believed that this software is likely to deter students’ plagiarism. The aim of this study is, therefore, to investigate1) the impact of Turnitin on students’ plagiarism from the perspectives of both students and instructors in a private Lebanese English-speaking university and 2) the reasons that push students to plagiarize. A concurrent mixed-methods design is employed, and different data collection methods are used. The data are analyzed quantitatively and qualitatively. Findings reveal that although a lot of the participants perceive Turnitin as a good deterrent to plagiarism, it did not completely inhibit it. The findings also reveal that not all instructors were committed enough to use Turnitin in their courses. Some of the reasons for plagiarism that the participants named are lack of citation skills, laziness, and indifference among students to abide by ethical writing norms.Besides reinforcing the use of Turnitin among all instructors, the researcher recommends that students’ writing and citation skills be improved and that students be helped to become more ethical writers.

RGO : Revista Gaúcha de Odontologia , 2010,
Abstract: Objective: To verify the association between periodontal disease and lung disease from an epidemiological, case and control survey, in patients who attended the first aid service of the Adriano Jorge Foundation Hospital, Manaus, Amazonas, Brazil, from June 2006 to February 2007. Methods: The sample consisted of 140 patients, among whom community-acquired pneumonia was present in 60% (n = 70), and chronic obstructive pulmonary disease in 40% (case-group); and 70 patients without respiratory disease (control group), ranging between 19 and 69 years of ages, with a mean age of 41.3, and standard deviation of 13.6 years. The clinical parameters for evaluating periodontal changes were obtained by means of pocket depth, bleeding on probing, plaque index and clinical attachment loss. Results: Both groups showed no significant difference in any of the control variables (p>0.05). The groups showed significant difference only in the plaque index (p <0.05) and the mean was 0.36, standard deviation 0.30 in control group, and in the cases a mean of 0.51, standard deviation 0.35. Conclusion: Periodontal disease showed no significant association with lung disease, both in severity and extension (p> 0.05). Due to the increase in the bacterial plaque index in the oral cavity of patients with respiratory diseases, further studies should be conducted to verify what the relationship between the two diseases is.
