    Octupole deformations play a significant role in the rare-earth region of the nuclear chart. We will study the ground state properties in the even-even Sm isotopes, and investigate the role of octupole deformation and its effect on several ground state properties, such as binding energy, binding energy per nucleon, neutron and proton mean radii, and two neutron separation energy. For this investigation covariant density functional theory with BCS approximation for the pairing correlation will be employed

    Identification of dynamic parameters and friction coefficients

    No full text
    This paper presents the method for identification of the dynamic parameters and coefficients of friction of planar robots. The dynamic equations of the robot are directly differentiated in order to find the identification Jacobian members. The set of base inertial parameters are determined symbolically and the identification procedure is developed with respect to them. A polynomial model is adopted for the joint frictions and the identification Jacobian is expressed in an extended form which allows identification of the friction coefficients along with the robot inertial parameters. The method has been applied to the robot under study and the practical results proved remarkable improvement in the robot mode

    Evaluation of Accuracy of Episiotomy Incision in a Governmental Maternity Unit in Palestine: An Observational Study

    Episiotomy should be cut at certain internationally set criteria to minimize risk of obstetric anal sphincter injuries (OASIS) and anal incontinence. )e aim of this study was to assess the accuracy of cutting right mediolateral episiotomy (RMLE). An institution-based prospective cohort study was undertaken in a Palestinian maternity unit from February 1, to December 31, 2016. Women having vaginal birth at gestational weeks ≥24 or birthweight ≥1000 g and with intended RMLE were eligible (n � 240). Transparent plastic films were used to trace sutured episiotomy in relation to the midline within 24-hour postpartum. )ese were used to measure incisions’ distance from midline, and suture angles were used to classify the incisions into RMLE, lateral, and midline episiotomy groups. Clinical characteristics and association with OASIS were compared between episiotomy groups. A subanalysis by profession (midwife or trainee doctor) was done. Less than 30% were RMLE of which 59% had a suture angle of <40° (equivalent to an incision angle of <60°). )ere was a trend of higher OASIS rate, but not statistically significant, in the midline (16%, OR: 1.7, CI: 0.61–4.5) and unclassified groups (16.5%, OR: 1.8, CI: 0.8–4.3) than RMLE and lateral groups (10%). No significant differences were observed between episiotomies cut by doctors and midwives. Most of the assessed episiotomies lacked the agreed criteria for RMLE and had less than optimal incision angle which increases risk of severe complications. A well structured training program on how to cut episiotomy is recommended.Non

    A joint research project between Birzeit University and the University of California-Davis6th Balkans Joint Conference and Exhibition to be held in Tirana, Albania, on 7-9 November 2018, at Expocity Albania. The Conference Theme “Water and Nature” brings attention to the need for preserving nature and exploring nature based solutions in order to overcome the water challenges, and to ensure better water supply and sewerage services and protection of the public health. The Balkans Joint Conference and Exhibition has truly established itself as a major knowledge sharing and networking event in the Western Balkans water sector. With an audience of over 450 participants from the Greater Balkan Region, the Conference offers a platform where water professionals, policymakers, and business professionals from the sector gather and discuss issues of concern, exchange information, and share experiences in an effort to help the further development of the water supply and wastewater sector in the Greater Balkan Region.This study entails planning, operation and assessment of two composting pilots using different mixture ratios of domestic organic waste, municipal sewage sludge, horse manure and saw dust. The first experiment, winter season, comprised five composting piles with different mixtures (ratio 2:1 wet weight) were prepared. The second experiment, summer period, carbon to nitrogen ratios (C: N) were tested for four mixed samples. Using plastic containers, various compost mixtures were processed in a greenhouse at Birzeit University Campus under controlled conditions (moisture, temperature and pH). In both experiments, no major deviations in the moisture content and pH values, but larger deviations were recorded in process temperature. Over the 100 experimental days during winter (first experiment), the temperature ranged from 7 °C to 41 °C compared with summer composting phase (23 0C to 66 0C). Samples from raw and finished compost were tested for physical, chemical and microbial quality parameters. The results revealed that the compost quality for the both experiments complied with U.S. EPA compost regulations. All samples of raw and finished compost were free from the Salmonella. During winter, results showed no major differences in the fecal coliforms and E. coli content (≤1000 CFU/g) in the finished compost from all compost piles. However, compost pile 3, a mixture of domestic organics, sludge and sawdust exceeded the fecal coliforms rule indicating low sludge stabilization degree. For the second experiment, the microbial indicators in the finished compost complied with U.S. EPA standards pertinent to fecal coliforms (≤1000 CFU/g) and Salmonella free in the finished compost. The reduction in mass weight of raw compost materials reached 58% for pile 2, during summer compared with 56 % for pile 5 during winter. Pile number 4 (two domestic organics and one sludge), processed during winter and pile 2 (one domestic organics, two manure, one sludge), processed during summer, complied with U.S. EPA (40 CFR Part 503) standards than other composting piles in two experimental periods. Composting variable mixtures of domestic organics, horse manure and municipal sludge forms an effective and a sustainable management technology for the reduction of operational expenditures of municipal waste management in Palestinian communities.University of California-Davis-Diamond Dubai Sustainability Research and Training Program (SRTP No. 201500387-02

    Complications of type 2 diabetes mellitus in Ramallah and al-Bireh : the Palestinian diabetes complications and control study (PDCCS)

    No full text
    Background: Type 2 diabetes mellitus (T2DM) is a growing pandemic that will lead, if not managed and controlled, to frequent complications, poor quality of life, and high rates of disability and death. Little is known about T2DM complications in Palestine. The aim of this study is to estimate the prevalence of T2DM complications in Ramallah and al-Bireh governorate of Palestine. Methods: The study was conducted in eleven primary healthcare clinics offering services for persons with T2DM. Macrovascular complications were assessed using the Diabetes complication index. Microvascular complications were measured by physical examinations and laboratory tests. Questionnaires, laboratory tests, and physical examinations were used to assess socio-demographic characteristics, co-morbidities and other risk factors. Results: 517 adult men and nonpregnant women participated in the study (166 men, 351 women). The response rate was 84%. Mean age and mean duration of diabetes were 58.1 and 9.4 years respectively. Prevalence of diagnosed microvascular and macrovascular complications was 67.2% and 28.6% respectively. 78.2% of the participants had poor glycemic control (HbA1c ≥ 7.0%). Conclusion: Significant proportions of persons with T2DM had macro- and microvascular complications and poor metabolic control. These findings are important for policy development and the planning of health services
