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.
A Spectrum Sensing Framework for UWB-Cognitive Network  [PDF]
Deah J. Kadhim, Saba Q. Jobbar
Wireless Sensor Network (WSN) , 2010, DOI: 10.4236/wsn.2010.28077
Abstract: Due to that the Ultra Wide Band (UWB) technology has some attractive features like robustness to multipath fading, high data rate, low cost and low power consumption, it is widely use to implement cognitive radio network. Intuitively, one of the most important tasks required for cognitive network is the spectrum sensing. A framework for implementing spectrum sensing for UWB-Cognitive Network will be presented in this paper. Since the information about primary licensed users are known to the cognitive radios then the best spectrum sensing scheme for UWB-cognitive network is the matched filter detection scheme. Simulation results verified and demonstrated the using of matched filter spectrum sensing in cognitive radio network with UWB and proved that the bit error rate for this detection scheme can be considered acceptable.
Water Transfer Methods in Response to Water Demand for Agricultural Practice at Chanchaga River and Tagwai Dam in Niger State, Nigeria
Musa, J. J.,Saba, V.
Journal of Environmental Issues and Agriculture in Developing Countries , 2011,
Abstract: Water remains the determinate factor in intensifying agricultural and non agricultural activities. Considerable investment in water transfer will improve availability of water for irrigation. Random selection method was used to administer questionnaires to the farmers on the irrigation scheme of Chanchaga River and other activities carried out in the area. Some of these questionnaires were also distributed to the farmers along the major course of the Tagwai dam. Farmers who have their farmlands upstream the Tagwai dam were observed as 77.05%, the midstream had a population 6.89% farmers while at the downstream, was 16.06%. A total of 315 copies of structured questionnaire were distributed to the respondents. It was observed that the water transfer for Agricultural (irrigation) purposes is relatively not enough. Consequently, it is recommended that government should make water available for farmers to have access at all time when needed for bountiful crop yield.

International Journal of Morphology , 2009, DOI: 10.4067/S0717-95022009000400038
Abstract: due to our interest in clarifying the congenic problems at the origin of the coronary arteries, we have published in the early 70′s a theory (borges et al., 1974) in which the coronary arteries would be the last pair of aortic arches that, at the beginning of the embryogenesis, would be connected with the previous arch, trunk of the lung's artery through a duct which we named "ductus coronarius".
Genetic diversity among varieties and wild species accessions of pea (Pisum sativum L.) based on SSR markers
J Nasiri, A Haghnazari, J Saba
African Journal of Biotechnology , 2009,
Abstract: To assess the genetic relations inPisum genus and to examine putative duplicate accessions, 20 pea varieties (Pisum sativum L.) with 57 accessions from wild Pisum species fulvum, subspecies (subsp.) asiaticum, elatius, thebaicum, abyssinicum, transcaucasicum and arvense were analyzed using 10 out of 20 microsatellite primer pairs. We genotyped all accessions. In total, 59 alleles were identified in whole collection. The maximum number of alleles (8 alleles) was obtained from the PEACPLHPP, AF004843, and AA43090 loci. The maximum number of private alleles (4) in the wild collection was detected in AF004843 locus but in the cultivar collection, it was detected in AA430902 and PSBLOX13.2 loci. Cluster analysis and principal coordinate analysis located accessions in 3 groups and cultivated varieties were obviously separated from the wild accessions. Analysis of molecular variance (AMOVA) revealed that the intergroups component of variance (29%) is lower than the intragroups component of variance (71%).

Z Khanjani,J Babapour,G Saba
Journal of Shahid Sadoughi University of Medical Sciences , 2012,
Abstract: Introduction: Today revising and rethinking of the appearance and eliminating its flaws, real or imaginary, through cosmetic surgery is the main concern of some individuals. This study was conducted in order to compare the body image, depression and anxiety disorders between applicants of cosmetic surgery and non-applicants. Methods: The present study is of cause–comparison type. Cosmetic surgery applicants involved 62 participants who were selected by available sampling from those who referred to specialized centers for cosmetic surgery in Urumia during a three-month period; the non-applicants were homogenized with applicants regarding their age, gender, and level of education who were selected from the applicants’ relatives. So the study subjects were 124 individuals. Data were collected via a questionnaire about demographic characteristics, SCL-90-R and PSDQ questionnaires. The data were submitted to SPSS (ver. 16) and were analyzed using descriptive statistics, multivariable analysis of variance (MANOVA), and t-test. Results: Results showed that there is a significant difference between applicants for cosmetic surgery and non-applicants in regard to body image, depression and anxiety disorders. Conclusion: Like other medical specialties, cosmetic surgical interventions should undergo precise clinical trial before exerting on the patients. Therefore, Assessment and encouraging patients to refer to psychiatrists and consultants before operation is significant.
Relationship between Osmotic Adjustment with Soluble Carbohydrates and Proline and Role of Osmotic Adjustment in Grain Yield of Wheat Lines under Drought Stress
Sh. Javanmardi,R. Fotovat,J. Saba
Journal of Science and Technology of Agriculture and Natural Resources , 2010,
Abstract: Osmotic adjustment is generally regarded as an important adaptation of wheat to drought. Because it helps to maintain turgor and cell volume, osmotic adjustment is often thought to promote growth, yield, or survival, of plants in dry soils. However, a physiological rationale for such views is lacking. This study was conducted to determine the effect of osmotic adjustment and some of its components on the wheat yield. Ten bread wheat cultivars were grown in pots under different watering levels using a split plot design. During grain filling stage, RWC, leaf sugar content, proline content and osmotic regulation were estimated by sampling flag leaf under normal and stress conditions. Main stem was used for measuring sugar content of different parts of stem. Although there were some differences in osmotic regulation in wheat lines, there were no relationships between yield and osmotic regulation. It was shown that these components probably have a little share in wheat osmotic regulation.
Characterizing Internet Video for Large-scale Active Measurements
Saba Ahsan,Varun Singh,J?rg Ott
Computer Science , 2014,
Abstract: The availability of high definition video content on the web has brought about a significant change in the characteristics of Internet video, but not many studies on characterizing video have been done after this change. Video characteristics such as video length, format, target bit rate, and resolution provide valuable input to design Adaptive Bit Rate (ABR) algorithms, sizing playout buffers in Dynamic Adaptive HTTP streaming (DASH) players, model the variability in video frame sizes, etc. This paper presents datasets collected in 2013 and 2014 that contains over 130,000 videos from YouTube's most viewed (or most popular) video charts in 58 countries. We describe the basic characteristics of the videos on YouTube for each category, format, video length, file size, and data rate variation, observing that video length and file size fit a log normal distribution. We show that three minutes of a video suffice to represent its instant data rate fluctuation and that we can infer data rate characteristics of different video resolutions from a single given one. Based on our findings, we design active measurements for measuring the performance of Internet video.
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.
