    Background The United Nations Relief and Works Agency for Palestine refugees in the Near East (UNRWA) has periodically estimated infant mortality rates among Palestine refugees in Gaza. These surveys have recorded a decline from 127 per 1000 live births in 1960 to 20.2 in 2008. Methods We used the same preceding-birth technique as in previous surveys. All multiparous mothers who came to the 22 UNRWA health centres to register their last-born child for immunization were asked if their preceding child was alive or dead. We based our target sample size on the infant mortality rate in 2008 and included 3128 mothers from August until October 2013. We used multiple logistic regression analyses to identify predictors of infant mortality. Findings Infant mortality in 2013 was 22.4 per 1000 live births compared with 20.2 in 2008 (p = 0.61), and this change reflected a statistically significant increase in neonatal mortality (from 12.0 to 20.3 per 1000 live births, p = 0.01). The main causes of the 65 infant deaths were preterm birth (n = 25, 39%), congenital anomalies (n = 19, 29%), and infections (n = 12, 19%). Risk factors for infant death were preterm birth (OR 9.88, 3.98–24.85), consanguinity (2.41, 1.35–4.30) and high-risk pregnancies (3.09, 1.46–6.53). Conclusion For the first time in five decades, mortality rates have increased among Palestine refugee newborns in Gaza. The possible causes of this trend may include inadequate neonatal care. We will estimate infant and neonatal mortality rates again in 2015 to see if this trend continues and, if so, to assess how it can be reversed. PMID:26241479

    High Radon levels are present in the granite and grandiositic rocks that. spread in sand dunes along coast of Gaza. Such materials are rich in uranium and T widely used in the construction of dwelling in the Gaza, and their contribution to high indoor Radon levels is most relevant.The present work aims to investigate approaches, measures and detection of indoor Radon level throughout Gaza Strip. Five hundred CR-39 dosimeters were distributed over six locations in the middle Yv-region of Gaza Strip. Results suggest that Radon concentrations range from l3.36 to 83.82 Bq/m 3 and a maximum value of 97.01 Bq/m 3 .The average Radon concentrations was 37.83 Bq/m 3 with standard deviation of 11.23.The results provide a framework for future studies that include a large, broader survey of Radon concentration in Palestine

    Full Text Available Background: iron deficiency anemia is the most common type of nutritional anemia; it has been recognized as an important health problem in Palestine. This study was conducted to estimate the prevalence and to identify possible risk factors of iron deficiency anemia among kindergarten children living in the marginalized areas of the Gaza Strip and to evaluate the effectiveness of supplementing oral iron formula in the anemic children. Methods: the study included 735 (384 male and 351 female kindergarten children. Data was collected by questionnaire interviews, anthropometric measurements, and complete blood count analysis. All iron deficient anemic children were treated using an oral iron formula (50 mg ferrous carbonate + 100 mg vitamin C /5 mL and the complete blood count was reassessed after three months. A univariate analysis and a multiple logistic regression model were constructed; crude and adjusted odds ratios (OR, and 95% confidence intervals (95% CI were calculated. Results: the overall prevalence of iron deficiency anemia was 33.5% with no significant differences between boys and girls. Significantly different prevalences of iron deficiency anemia were reported between different governorates of the Gaza Strip. Governorate, low education level of the parents and smoking are significant risk factors for children developing anemia. Significantly lower complete blood count parameters, except for WBC, were reported in anemic children. The oral iron treatment significantly improved hemoglobin concentrations, and normalized the iron deficiency marker. Conclusions: iron deficiency anemia is a serious health problem among children living in the marginalized areas of the Gaza Strip, which justifies the necessity for national intervention programs to improve the health status for the less fortunate development areas.

    The construction industry is one of the most hazardous industries in developing countries. Understanding the safety climate or culture of a workplace, the perceptions and attitudes of workforce are important factors in assessing safety needs. The construction industry in Palestine, by its inherent nature, is susceptible to potentially dangerous conditions that affect the safety of all personnel working in construction projects. This paper reports, based on a questionnaire survey, the perception of owners, consultants and contractors towards safety in the Gaza Strip. The results showed that, most of the participants in the survey had accidents in their construction projects. The findings indicated that, main causes of fatalities and injuries are falling from heights, dropped objects and materials and being caught under excavations. Carelessness of workers, lack of safety knowledge and lack of safety training are the main three reasons that contributed to the increase rate of accidents among construction workers in the Gaza Strip. Therefore, contactors should prepare safety training programs which help personnel to carry out various accidents preventive activities effectively. Training material should discuss the cost of accidents, the influence of good safety performance and should stress the safety objectives of the company, the relevant laws and legislation and contractual relationships with clients regarding safety matters.

    The prevalence of metabolic syndrome is raising worldwide; however, the role of diet in the origin of metabolic syndrome is not understood well. This study identifies major dietary patterns among type 2 diabetes mellitus patients with and without metabolic syndrome; and its association with metabolic syndrome components in Gaza Strip, Palestine. This cross sectional study was conducted among 1200 previously diagnosed type 2 diabetes mellitus (both genders, aged 20 - 64 years) patients receiving care in primary healthcare centers in Gaza Strip, Palestine. Metabolic syndrome was defined based on the International Diabetes Federation criteria; dietary patterns were evaluated using a validated semi-quantitative food frequency questionnaire. Statistical analysis was performed using SPSS version 20. Two major dietary patterns were identified by factor analysis: Asian-like pattern and sweet-soft drinks-snacks pattern. After adjustment for confounding variables, patients in the highest tertile of the Asian-like pattern characterized by a high intake of whole grains, potatoes, beans, legumes, vegetables, tomatoes and fruithad a lower odds for (Metabolic syndrome, central obesity, high triglycerides, low HDL cholesterol and high blood pressure), (OR 0.766 CI 95% (.642-.914)), (OR 0.797 CI 95% (.652-.974)), (OR 0.791 CI 95% (.687-.911)), (OR 0.853 CI 95% (.743-.978)) and (OR 0.815 CI 95% (.682-.973)) respectively, (P value metabolic syndrome and its components. The Asian-like pattern may be associated with a lower prevalence of metabolic syndrome and its components among type 2 diabetes patients.

Nusantara Bioscience 6: 26-32. Wastewater disposal into the Mediterranean coast of the Gaza Strip has many negative effects, whether on the environment or on human health, thus microbiological analysis of seawater samples was carried out. The microbial analysis was confined on two types of fecal indicators (fecal coliform and fecal streptococci, in addition to a single type of bacteria (pseudomonas. This study was conducted between the beginning of July 2012 to the mid of October 2012 over an area extended from the proposed Khan Younis fishing port to Gaza fishing port, with a length of about 23 km. The study area was divided into five zones. The samples were collected in two rounds: the first round included 75 samples that collected along the study area during the summer season. The second round included 19 samples that collected in the autumn season to compare it with their counterparts that have been collected in the summer season. Laboratory analysis showed the presence of contamination in many of these samples. The results also showed that the pollution was concentrated in and surrounding the mouths of wastewater outfalls. Depending on the microbial analyses, which have been collected in the first round, the fecal coliform appeared in 61% of the samples, while fecal streptococci appeared in all samples and pseudomonas appeared in 33% of the samples. The pollutants were widespread along the study area, which are the result mainly from wastewater discharge into the sea. A risk analysis was done for season variations using the second moment method; in general, it was found that risk in both seasons was high especially in summer.

    Assessment of the prevailing safety culture within the Gazan health care system can be used to identify problem areas. Specifically, the need for improvements, raising awareness about patient safety, the identification and evaluation of existing safety programs and interventions for improving the safety culture. This study aims to assess the safety culture in the neonatal intensive care units (NICUs) in Gaza Strip hospitals and to assess the safety culture in regards to caregivers' characteristics. In a cross-sectional study using a census sample, we surveyed all nurses and physicians working in at all the NICUs in the Gaza Strip, Palestine. The Safety Attitudes Questionnaire (SAQ) which includes six scales was used to assess participants' attitudes towards safety culture. The overall score for SAQ was 63.9. Domains' scores ranged between 55.5 (perception of management) and 71.8 (stress recognition). The scores reported by our participants fell below the 75 out of a possible score of 100, which was considered as a cut-off point for a positive score. Moreover, our results revealed substantial variation in safety culture domain scores among participating NICUs. These results should be an indicator to our health care policy makers to modify current or adopt new health care policies to improve safety culture. It should also be a call to design customized programs for improving the safety culture in NICUs in the Gaza Strip. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Interprofessional collaboration and teamwork between nurses and physicians is essential for improving patient outcomes and quality of health services. This study examined the attitudes of nurses and physicians toward nurse-physician collaboration. A cross-sectional study was conducted among nurses and physicians (n=414 in two main referral public hospitals in the Gaza Strip using the Arabic Jefferson Scale of Attitude toward Physician-Nurse Collaboration. Descriptive statistics and difference of means, proportions, and correlations were examined using Student’s t-test, one-way ANOVA, and Pearson correlation and p<0.05 was considered as statistical significant. Response rate was 42.8% (75.6% for nurses and 24.4% for physicians. Nurses expressed more positives attitudes toward collaboration than physicians (M ± SD on four-point scale: 3.40±0.30 and 3.01±0.35, resp. and experience duration was not proved to have an interesting influence. Teamwork approach in the professional practice should be recognized taking into consideration that the relationship between physicians and nurses is complementary and nurses are partners in patient care.

    Seawater intrusion is one of the major threats to freshwater resources in coastal areas, often exacerbated by groundwater overexploitation. Mitigation measures are needed to properly manage aquifers, and to restore groundwater quality. This study integrates three computational tools into a unified framework to investigate seawater intrusion in coastal areas and to assess strategies for managing groundwater resources under natural and human-induced stresses. The three components are a three-dimensional hydrogeological model for density-dependent variably saturated flow and miscible salt transport, an automatic calibration procedure that uses state variable outputs from the model to estimate selected model parameters, and an optimization module that couples a genetic algorithm with the simulation model. The computational system is used to rank alternative strategies for mitigation of seawater intrusion, taking into account conflicting objectives and problem constraints. It is applied to the Gaza Strip (Palestine) coastal aquifer to identify a feasible groundwater management strategy for the period 2011-2020. The optimized solution is able to: (1) keep overall future abstraction from municipal groundwater wells close to the user-defined maximum level, (2) increase the average groundwater heads, and (3) lower both the total mass of salt extracted and the extent of the areas affected by seawater intrusion.

    The aim of this study was to evaluate the adherence to anti-diabetic medications among patients with type 2 diabetes mellitus (DM) seeking medical care in the Gaza Strip, Palestine. A cross-sectional study was conducted among 369 primary care patients with type 2 DM from October to December 2016. Adherence to medications was measured using the Morisky Medication Adherence Scale (MMAS-4). Socio-demographic and clinical variables, provider-patient relationship, health literacy, and health belief were examined for each patient. Univariate, binary logistic regression and multiple linear regression were applied to determine the independent factors influencing adherence to anti-diabetic medications using SPSS version 22. Of all the respondents, 214 (58%), 146 (39.5%), and nine (2.5%) had high (MMAS score = 0), medium (MMAS score = 1 + 2), and low (MMAS score ≥ 3) adherence to anti-diabetic medications, respectively. Factors that were independently associated with adherence to anti-diabetic medications were as follows: female gender [odds ratio (OR): 1.657, 95% confidence interval (CI): 1.065-2.578] and perception of disease's severity (OR: 1.510, 95% CI: 0.410-5.560). Elderly ( t  = 1.345) and longer duration of DM ( t  = 0.899) were also predictors of adherence but showed no statistical significance ( p  > 0.05). The level of complete adherence to anti-diabetic medications was sub-optimal. New strategies that aim to improve patients' adherence to their therapies are necessary taking into consideration the influencing factors and the importance of having diabetes educators in the primary care centers.

    Stunting continues to be a major public health problem in developing countries. It is one of the most important risk factors for morbidity and mortality during childhood. In Palestine, it is another health problem, which adds to the catastrophic issues in the region. This study aimed to determine the prevalence of stunting and its associated factors among preschool children in the Gaza Strip. A cross-sectional study design was conducted in the Gaza Strip. A total of 357 children aged 2-5 years and their mothers aged 18-50 years were recruited. A multistage cluster sampling was used in the selection of the study participants from three geographical areas in the Gaza Strip: Jabalia refugee camp, El Remal urban area, and Al Qarara rural area. A structured questionnaire was used for face- to -face interviews with the respective child's mother to collect sociodemographic information and feeding practice. Anthropometric measurements for children were taken to classify height-for-age (HAZ), while maternal height was measured as well. Descriptive and binary logistic regression analyses were applied to determine the prevalence and associated factors with stunting. The total prevalence of stunting in this study was 19.6%, with the highest prevalence being (22.6%) in Jabalia refugee camp. It turns out that shorter mothers had increased the odds of stunting in preschool children in the Gaza Strip. Children born to mothers whose height was 1.55-1.60 m or 1.60 m. Moreover, parental consanguinity increased the risk of stunted children (p = 0. 015). This study showed the prevalence of stunting was of alarming magnitude in the Gaza Strip. Our results also demonstrated that parental consanguinity and short maternal stature were associated with stunting. Culturally appropriate interventions and appropriate strategies should be implemented to discourage these types of marriages. Policy makers must also raise awareness of the importance of the prevention and control of

    The Quaternary rocks of the Gaza Strip mainly consist of clastic sedimentary rocks. In Wadi Gaza, the outcropping rocks consist of brownish fine-grained deposits, sandstones, and conglomerates. The deposits have been studied from a genetic point of view, and six facies have been described: (i) graded clast-supported conglomerates, (ii) cross-bedded clast-supported conglomerates, (iii) sandy matrix conglomerates, (iv) cross-laminated medium-grained sandstones, (v) graded coarse-grained sandstones, and (vi) massive sandstones. The field work observations and granulometric analysis show that the sphericity of the grains increase toward the west, where its value ranges from ∼0.64 in the east to ∼0.70 in the west. In addition, the grain forms tend to be disc shape in the east, whereas they tend to be disc-to spheroid shape in the west, and they become well rounded to well sorted toward the west. Moreover, the features, geometry, and spatial relationship among these facies suggest that the Wadi Gaza was meandering wadi fed from Beir Sheva and the Northern Negev in the southeast of Gaza Strip through Wadi Al Shallala and Wadi Sheneq and from Hebron mountains in the West Bank at the east through Wadi Al Shari'a alluvials. Within the Gaza Strip, paleocurrent data ranges from 210° to 310°, indicating a mean a paleoflow direction to the W (276°) and a median value about 275°. The sedimentary rocks in the Wadi Gaza are considered to be deposited in two periods of climate conditions: the coarse-grained rocks were deposited during the period of wet condition before 12.4 ka age, whereas the eolinite fine-grained rocks were deposited during semiarid climate conditions which are younger in age than 12.4 ka.

    The increasing number of obesity and overweight cases in developing countries, especially among women, requires serious attention because of its effects on the health care system and the quality of life. Few studies have been conducted in the Gaza Strip to determine obesity and overweight prevalence and the associated factors. This study aimed at determining the prevalence of obesity and overweight cases in relation to socio-demographic factors among mothers aged 18-50 years in the Gaza Strip-Palestine from June 2012 to September 2012. Mothers childbearing age 18-50 years (n = 357) were selected using a cross-sectional multistage sampling methodology from three different geographical locations, namely, El Remal urban area, Jabalia refugee camp, and Al Qarrara rural area. The weight and height of the mothers were measured, and their body mass indexes (BMI) were computed. The mothers were categorized according to the criteria of World Health Organization (WHO) for BMI. The criteria categorize mothers as overweight if they have a BMI 25-29.9 kg/m(2) and obese if their BMI ≥ 30.0 kg/m(2). Obesity and overweight rates in urban area, refugee camp, and rural area were found to be 57.0%, 66.8%, and 67.5%, respectively. Moreover, BMI increased with age, adjusted b = 0.39; 95% CI (0.31, 0.48); p = < 0.001, whereas BMI was lower in low-income subjects, adjusted b = -1.59, 95% CI (-2.74,-0.44), p = 0.007. Housewives were more susceptible to obesity than employed woman, adjusted b = -2.76, 95% CI (-5.33,-0.19), p = 0.036. However, the study found no association among BMI level and household size, geographical location, educational level, and family assistance. The results showed that obesity and being overweight are highly prevalent among women in the Gaza Strip. Independent predictors of obesity in the population studied were increasing age, high income, and housewives. This finding is an important baseline for the monitoring of obesity and

    We have developed a new methodology for assessing solid waste management in a situation of armed conflict. This methodology is composed of six phases with specific activities, and suggested methods and tools. The collection, haulage, and disposal of waste in low- and middle-income countries is so complicated and expensive task for municipalities, owing to several challenges involved, that some waste is left in illegal dumps. Armed conflicts bring further constraints, such as instability, the sudden increase in violence, and difficulty in supplying equipment and spare parts: planning is very difficult and several projects aimed at improving the situation have failed. The methodology was validated in the Gaza Strip, where the geopolitical situation heavily affects natural resources. We collected information in a holistic way, crosschecked, and discussed it with local experts, practitioners, and authorities. We estimated that in 2011 only 1300 tonne day(-1) were transported to the three disposal sites, out of a production exceeding 1700. Recycling was very limited, while the composting capacity was 3.5 tonnes day(-1), but increasing. We carefully assessed system elements and their interaction. We identified the challenges, and developed possible solutions to increase system effectiveness and robustness. The case study demonstrated that our methodology is flexible and adaptable to the context, thus it could be applied in other areas to improve the humanitarian response in similar situations. © The Author(s) 2014.

    Celiac disease (CD) diagnosis can be established by serological and small bowel biopsy (SBB), while absence of HLA-DQ2 and -DQ8 haplotypes excludes the disease. The present study aims at evaluating the diagnosis of a representative sample of pediatric and adult CD patients of Gaza strip in light of DQ2 and DQ8 haplotypes expression. Unrelated CD patients (n = 101) and matched healthy controls (n = 97) were genotyped for DQA1*05, DQB1*02 and DQB1*03:02 alleles by allele-specific real-time PCR. The diagnosis was re-evaluated according to the patient laboratory tests and HLA-DQ genotype. The diagnosis of 35 patients who have been managed for CD could not be confirmed. Twenty-five of them were diagnosed upon their clinical presentation only. The remaining were either negative for serological and SBB tests or negative for HLA-DQ haplotypes. The HLA-DQ alleles were negative in 4 SBB and one Anti-EMA positive patients. The frequency of DQ2 and DQ8 haplotypes among the remaining 65 confirmed cases was 70.8 and 15.4%, respectively, compared to 17.5 and 27.8% in the controls. The DQB1*02 allele was the most common in the cases (84.6%) followed by DQA1*05 allele (80%) and DQB1*03:02 allele (20%). The DQA1*05 allele was commonest in the control group (54.6%) followed by DQB1*02 allele (42.3%) and DQB1*03:02 allele (28.9%). Absence of HLA-DQ2 and HLA-DQ8 genotyping in the workup of patients may result in CD misdiagnosis, particularly in a setting with poor histopathological diagnostic capacity.

    Full Text Available OBJECTIVE: Nutritional deficiencies are very significant to the overall health of humans at all ages and for both genders, yet in infants, children and women of childbearing age these deficiencies can seriously affect growth and development. The present work is aimed to assess homocysteine and vitamin B12 status in females with iron deficiency anemia from the Gaza Strip.METHODS: Venous blood samples were randomly collected from 240 female university students (18-22 years old and parameters of the complete blood count, serum ferritin, homocysteine and vitamin B12 were measured. Statistical analysis included the t-test and analysis of variance (ANOVA using the IBM SPSS software (version 18. Statistical significance was set for p-values <0.05.RESULTS: The results revealed that 20.4% of the students have iron deficiency anemia. The mean serum vitamin B12 level in females with iron deficiency anemia (212.9 ± 62.8 pg/mL was significantly lower than in normal controls (286.9 ± 57.1 pg/mL and subjects with microcytic anemia and normal ferritin (256.7 ± 71.1 pg/mL. Significantly higher serum homocysteine levels were reported in the iron deficiency anemia group (27.0 ± 4.6 µmol/L compared to normal controls (15.5 ± 2.9 µmol/L and in subjects with microcytic anemia and normal ferritin (18.1 ± 2.7 µmol/L. Statistically significant negative correlations were reported for serum homocysteine with serum ferritin, vitamin B12, hemoglobin, and hematocrit levels.CONCLUSION: Important associations were found between serum homocysteine and markers of iron deficiency. Monitoring homocysteine levels might be essential to understand the development of different clinical conditions including anemia. It seems necessary to conduct prospective trials to determine whether treating anemia ameliorates homocysteine levels.

    Full Text Available Abstract The conflict between Israel and Palestine on Gaza Strip has caused not only military casualties but also civilian casualties which are protected by the international law. The protection of civilians in armed conflict is basically set in the Geneva Convention of 1949 which has been ratified by Israel and Palestine, in which violations of its provisions constitute war crimes. This paper discusses the mechanism of the International Criminal Court based on the Rome Statute 1998 in enforcing the law against war crimes on Gaza Strip. Articles 13 and 15 of Rome Statute 1998 provide jurisdiction for the settlement of an international criminal case. Palestine has made several attempts in accepting the jurisdiction of the ICC in 2009 and 2015, namely through their declaration and accession which further gave legal implication on the implementation of the international law. Based on these studies, this paper will further discuss the legal implication of the Palestine's declaration in 2009 and 2015, as well as its accession in 2015. Abstrak Konflik yang telah terjadi bertahun-tahun antara Israel dan Palestina di jalur Gaza telah memakan tidak hanya korban militer namun juga korban sipil yang dilindungi oleh hukum internasional. Perlindungan terhadap penduduk sipil dalam konflik bersenjata pada dasarnya diatur dalam Konvensi Jenewa IV tahun 1949 yang telah diratifikasi oleh Israel dan Palestina di mana pelanggaran terhadap ketentuannya merupakan kejahatan perang. Penulis dalam tulisan ini membahas mengenai mekanisme International Criminal Court berdasarkan Statuta Roma 1998 dalam menegakkan hukum terhadap kejahatan perang di jalur Gaza. Berdasarkan Statuta Roma 1998 Pasal 13 dan 15, ICC memiliki yurisdiksi atas penyelesaian suatu kasus pidana internasional yang diajukan negara anggota, rekomendasi Dewan Keamanan PBB, investigasi mandiri yang dilakukan oleh jaksa Mahkamah Pidana Internasional, atau deklarasi ad hoc yang dilakukan bagi negara bukan

    Full Text Available Sediment load materials is one of the key factors that determine the surface water quality, both of oceanic and river water, and it specifies water optical properties. Thus it provides a background for a plenty of applications and projects in the water and oceanography community. Landsat detects and classifies reflected solar energy from bodies on the earth's surface. Suspended sediments existing in water column have an optical influences. So that, Landsat images could detect suspended sediments concentration in such a water surface. In this study we have three main objectives to be achieved as; TSS Concentration maps generation in the Gaza Strip coastal zone, achieving analysis processes on TSS trend itself and TSS related coastal phenomenon, and investigation of the ability of Landsat images to detect TSS comprehensively in a wavy coastal zone. For this purpose two landsat TM5 images acquired in 1999 and 2010, one Landsat TM7 images acquired in 2003, and 2 Landsat Oli 8 images acquired in 2014 and 2015 were used for TSS mapping. In addition, 64 TSS in-situ tested samples were also to calculate a correlation equation between Digital Numbers - DN in each image pixels and TSS values in the ground data. All image analysis and remote sensing steps have been done in this study using Integrated Land and Water Information System - ILWIS software version ILWIS academic 3.3. Green and Red bands in all used Landsat images contained the highest linear correlation factors -R- for the images acquired in 1999, 2003, 2010, 2014, and 2015. Resulted correlation factors were higher by reducing time difference between acquisition time and sampling time. Generated maps showed that circulation in Gaza coastal area are counterclockwise, and it brings the sediments from Nile River Delta toward Gaza Strip.

    Theoretical assessments of power density in far-field conditions were used to evaluate the levels of environmental electromagnetic frequencies from selected GSM900 macrocell base stations in the West Bank and Gaza Strip. Assessments were based on calculating the power densities using commercially available software (RF-Map from Telstra Research Laboratories-Australia). Calculations were carried out for single base stations with multi-antenna systems and also for multiple base stations with multi-antenna systems at 1.7 m above the ground level. More than 100 power density levels were calculated at different locations around the investigated base stations. These locations include areas accessible to the general public (schools, parks, residential areas, streets and areas around kindergartens). The maximum calculated electromagnetic emission level resulted from a single site was 0.413 μW cm -2 and found at Hizma town near Jerusalem. Average maximum power density from all single sites was 0.16 μW cm -2 . The results of all calculated power density levels in 100 locations distributed over the West Bank and Gaza were nearly normally distributed with a peak value of ∼0.01% of the International Commission on Non-Ionizing Radiation Protection's limit recommended for general public. Comparison between calculated and experimentally measured value of maximum power density from a base station showed that calculations overestimate the actual measured power density by ∼27%.

    In the Mediterranean region, particularly in the Gaza strip, an increased risk of drought is among the major concerns related to climate change. The impacts of climate change on water availability, drought risk and food security can be assessed by means of hydro-climatological modeling. However, the region is prone to severe observation data scarcity, which limits the potential for robust model parameterization, calibration and validation. In this study, the physically based, spatially distributed hydrological model WaSiM is parameterized and evaluated using satellite imagery to assess hydrological quantities. The Triangle Method estimates actual evapotranspiration (ETR) through the Normalized Difference Vegetation Index (NDVI) and land surface temperature (LST) provided by Landsat TM imagery. So-derived spatially distributed evapotranspiration is then used in two ways: first a subset of the imagery is used to parameterize the irrigation module of WaSiM and second, withheld scenes are applied to evaluate the performance of the hydrological model in the data scarce study area. The results show acceptable overall correlation with the validation scenes (r=0.53) and an improvement over the usual irrigation parameterization scheme using land use information exclusively. This model setup is then applied for future drought risk assessment in the Gaza Strip using a small ensemble of four regional climate projections for the period 2041-2070. Hydrological modeling reveals an increased risk of drought, assessed with an evapotranspiration index, compared to the reference period 1971-2000. Current irrigation procedures cannot maintain the agricultural productivity under future conditions without adaptation. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background The present work aims at determining HCV genotypes in patients with chronic HCV infection, in Gaza strip, Palestine. The most common risk factors for HCV transmission were also evaluated in conjunction with the genotyping data. Results The study shows that there are only two major genotypes of HCV in Gaza Strip: Genotype 1 (subtypes 1a and 1b collectively contribute to 28.3% of the cases, and genotype 4 (subtypes 4a and 4c/d collectively contribute to 64.1% of the cases. Mixed infection with the two genotypes was also present among 7.6% of the cases. In this study a statistically significant relationship was established between the distribution of these genotypes and the patients' living place, traveling history, history of blood transfusion and history of surgical operations. Conclusion The present study is the first to link HCV genotyping in Gaza strip with its possible roots of transmission. Traveling to endemic countries, especially Egypt; blood transfusion and surgical operations are major roots of HCV infection in Gaza strip. The results indicate that iatrogenic and nosocomial procedures may be responsible for the majority of HCV infections in Gaza strip.

    Full Text Available Background: The Rh blood group system is the second most clinically significant blood group system. It includes 49 antigens, but only five (D, C, E, c and e are the most routinely identified due to their unique relation to hemolytic disease of the newborn (HDN and transfusion reactions. Frequency of the Rh alleles showed variation, with regard to race and ethnic. Objectives: The purpose of the study was to document the Rh alleles′ frequencies amongst males (M and females (F in Gaza city in Palestine. Materials and Methods: Two hundred and thirty-two blood samples (110 M and 122 F were tested against monoclonal IgM anti-C,anti-c, anti-E, anti-e and a blend of monoclonal/polyclonal IgM/IgG anti-D. The expected Rh phenotypes were calculated using gene counting method. Results: The most frequent Rh antigen in the total sample was e, while the least frequent was E.The order of the combined Rh allele frequencies in both M and F was CDe > cDe > cde > CdE > cDE > Cde > CDE. A significant difference was reported between M and F regarding the phenotypic frequencies (P < 0.05. However, no significance (P > 0.05 was reported with reference to the observed and expected Rh phenotypic frequencies in either M or F students. Conclusion: It was concluded that the Rh antigens, alleles and phenotypes in Gaza city have unique frequencies, which may be of importance to the Blood Transfusion Center in Gaza city and anthropology.

    A high prevalence of dental fluorosis has been identified among children in the Gaza Strip. This study aimed to determine the history of breastfeeding and dietary behaviours among children in the Gaza Strip and to examine potential associations with the prevalence and severity of dental fluorosis. A cross-sectional study recruited a stratified cluster random sample of 350 children aged 12-18 years and their mothers. Data about dietary behaviours in the first 7 years of life were collected by interview questionnaire. Dental fluorosis was determined using the Thyllstrup-Fejerskov index. A majority of children were breastfed exclusively in the first 6 months (82.9%) but 98.1% were given tea in the first year of life. The prevalence of dental fluorosis was 78.0%. Both intake of animal proteins and plant proteins were negatively associated with the prevalence and severity of dental fluorosis. Further studies to investigate fluoride intake is required to plan preventive interventions.

    Food security is a major issue in Palestine for both political and physical reasons, with direct effects on the local population living conditions: the nutritional level of people in Gaza is classified by FAO as "insecure". As most of the protein supply comes from irrigated agricultural production and aquaculture, freshwater availability is a limiting factor to food security, and the primary reason for frequent conflicts among food production processes (e.g. aquaculture, land livestock or different types of crops). In this study we use Life Cycle Analysis to assess the environmental impacts associated to all the stages of water-based protein production (from agriculture and aquaculture) in the Gaza strip under different agricultural scenarios and hydroclimatic variability. As reported in several recent studies, LCA seems to be an appropriate methodology to analyze agricultural systems and assess associated food security in different socio-economic contexts. However, we argue that the inherently linear and static nature of LCA might prove inadequate to tackle with the complex interaction between water cycle variability and the food production system in water-scarce regions of underdeveloped countries. Lack of sufficient and reliable data to characterize the water cycle is a further source of uncertainty affecting the robustness of the analysis. We investigate pros and cons of LCA and LCA-based option planning in an average size farm in Gaza strip, where farming and aquaculture are family-based and integrated by reuse of fish breeding water for irrigation. Different technological solutions (drip irrigation system, greenhouses etc.) are evaluated to improve protein supply and reduce the pressure on freshwater, particularly during droughts. But this use of technology represent also a contribution in increasing sustainability in agricultural processes, and therefore in economy, of Gaza Strip (reduction in chemical fertilizers and pesticides etc.).

    This study aimed at comparing primary school students' anthropometry to the dimensions of school furniture and determining whether the furniture used matches the students' anthropometry. A sample of 600 male students, whose ages were between 6 and 11 years, from five primary schools in the Gaza Strip governorates participated in the study. Several students' body dimensions were measured. The dimensions measured included elbow-seat height, shoulder height, knee height, popliteal height and buttock-popliteal length. Measurements of the dimensions of the classroom furniture indicated that there was a considerable mismatch between the students' body dimensions and the classroom furniture. The mismatches in seat height, seat depth and desk height occurred for 99% of the students, while the mismatch for the back rest height was only 35%. Two design specifications were proposed in order to decrease the mismatch percentage based on the data obtained. The two proposed designs showed a considerable improvement in the match percentages as compared to the existing design. STATEMENT OF RELEVANCE: Having identified mismatches between the dimensions of the school furniture used in primary schools in the Gaza Strip, two new design specifications are proposed and shown to improve match with the students' anthropometric dimensions. The findings of the study are also an important addition to local knowledge on school children's anthropometry.

    Full Text Available Abstract Coeliac disease is an important clinical disorder affecting the human gastrointestinal tract leading to multiple signs and symptoms in different body organs. This disease was the subject of a cross sectional descriptive-analytic study conducted in the Gaza Strip during 2010. Objectives were oriented to identify and verify several variables and attributes affecting the prognosis of coeliac disease in the patients. Ninety five children out of 113 patients were arranged into two groups according to age from 2 to 11 years and from 12 to 18 years old. Results showed the poor interest of health professionals regarding coeliac disease in the Gaza Strip. The mean age of study population was 5.47 years for males and 8.93 years for females. The lifestyle of coeliac patients was directly proportional with better nutritional indictors. Poor recognition of the emblem illustrating gluten in foods implicates effective health awareness or promotion. The more knowledgeable patients or mothers (P = 0.036 were the more compliant. The compliance to giving gluten free foods outside home was statistically significant (P = 0.037. Similarly, cautious approach when buying foods or detergents (P = 0.011. According to BMI 74.4%, 23.4% and 3.2% of all patients were normal, underweight and overweight respectively. Albumin blood level was normal in 32.6% and low in 67.4%. Meanwhile, blood calcium level was normal in 76.8%, low in 21.1% and high in 2.1% of all patients. Conclusion: The study showed that recreation and social activities for coeliac patients are substantially missing in the Gaza Strip. Moreover, the study proved that AEI is a reliable centre for care of coeliac disease patients and conducting relevant studies. Recommendation: There is a need for thorough and continuous community and institutional mobilization regarding coeliac disease in the Gaza Strip and in Palestine.

    This study was designed to estimate the birth prevalence of children with congenital heart disease born in the Gaza Strip during 2010 and to compare these with estimates from elsewhere. We reviewed the medical records of all children born in 2010 who were diagnosed, treated, and/or followed up in the four paediatric cardiology clinics in the Gaza Strip. Data were also obtained from El Makassed Hospital in East Jerusalem and from the Schneider Hospital, Wolfson Medical Center, and Tel HaShomer Hospital in Israel, where we had referred some of our patients for percutaneous or surgical treatment. A total of 598 children with congenital heart disease were detected among the 59,757 children born alive in the Gaza Strip during 2010, yielding a birth incidence of 10 per 1000 live births. The most frequently occurring conditions were ventricular septal defects (28%), ostium secundum atrial septal defects (17%), patent ductus arteriosus (8.5%), and pulmonary valve abnormalities (8%). In this study, 7% of the children died. The actuarial survival at 6 months and 1 year of age was 94% and 93%, respectively, and remained stable over 18 months of follow-up. The birth incidence of congenital heart disease in the Gaza Strip in 2010 (10 per 1000) is higher than most estimates in Western Europe (8.2 per 1000 live births) and North America (6.9 per 1000 live births) but is similar to estimates from other parts of Asia (9.3 per 1000 live births).

    Water scarcity and food security are major issues in the Gaza Strip. This area is characterized by one of the highest densities in the world and it is affected by both severe scarcity of water resources and limited trading possibilities.Given this context, the enhancement of domestic food production is considered a fundamental strategy in achieving food security in the area. For this reason, rural people play a crucial role in implementing sustainable strategies for enhancing the domestic food production while preserving water resources. In order to investigate the effectiveness of existing agricultural scenarios in achieving food security in a sustainable manner, we propose a framework to assess food production systems in terms of their contribution to the nutritional and economic conditions of rural households and their impact on water resources. In particular, the latter has been carried out through the water footprint indicator proposed by the Water Footprint Network. The case study analyzed is a sample farm located in the Gaza Strip, whose food production is based on horticulture, animal husbandry and aquaculture. The study is articulated into two main parts: first, we compare alternative scenarios of vegetal and animal food production in terms of food supply, water consumption and economic income at the household scale; then, we extend the analysis to evaluate the potential contribution of domestic food production to the food security in the whole Gaza Strip, focusing on the nutritional dimension, and providing a preliminary assessment of the environmental and economic sustainability. In particular, we evaluate water appropriation for domestic food production and compare it with the availability of water resources in the region. The outcomes highlight that the domestic food production can potentially satisfy both a basic diet and economic income for rural household, but the related appropriation of freshwater results unsustainable with respect to the fresh

    Seawater pollution problems are gaining interest world wide because of their health impacts and other environmental issues. Intense human activities in areas surrounding enclosed and semi-enclosed seas such as the Mediterranean Sea always produce in the long term a strong environmental impact in the form of coastal and marine degradation. This paper is concerned with the use of ANNs (Artificial Neural Networks) MLP ( Multilayer Perceptron) model for the prediction of pH and EC (Electrical Conductivity) in water quality parameters along Gaza city coast. MLP neural networks are trained and developed with reference to three major oceanographic parameters (water temperature, wind speed and turbidity) to predict the values of pH and EC; these parameters are considered as inputs of the neural network. The data collected comprised of four years and collected from nine locations along Gaza coastline. Results show that the model has high capability and accuracy in predicting both parameters. The network performance has been validated with different data sets and the results show satisfactory performance. Results of the developed model have been compared with multiple regression statistical models and found that MLP predictions are slightly better than the conventional methods. Prediction results prove that the proposed approach is suitable for modeling the water quality in the Mediterranean Sea along Gaza. (author)

    The Israeli attack on the Gaza Strip from 27 December 2008 to 19 January 2009 was characterised by gross, unprecedented human rights violations, which were the result of a deliberate political decision to overlook the loss of civilian lives in order to save those of Israeli soldiers. These violations included attacking medical personnel and civilians, impeding emergency medical evacuations, restricting health care for the civilian population, preventing referral to care outside the Gaza Strip and jeopardising distribution of medical supplies and food. This article will focus on the right to health of Palestinians under Israeli occupation by presenting case studies that have been collected by Physicians for Human Rights-Israel. It will emphasise how the Palestinian medical system has been stretched to its breaking point, severely and negatively affecting the provision of medical services; the consequences of denying patients referral to care outside the Gaza Strip; and other severe violations of human rights. It will conclude by reiterating that only the withdrawal of Israeli occupation from Palestinian land can guarantee the right to health of Palestinians.

    A positive association between dental fluorosis prevalence and fluoride (F) concentration in drinking waters has been detected in Gaza Strip. Total Daily Fluoride Retention (TDFR), and Fractional Urinary Fluoride Excretion (FUFE) indicate F body burden; important in assessing fluorosis risk in susceptible age groups. 1, To determine and compare Daily Urinary Fluoride Excretion (DUFE) and FUFE of 3-4-year-olds living in lower ( 1.2 ) ppm F tap water areas; 2, To determine any relationship between i, DUFE and tap water F; ii, DUFE and Total Daily Fluoride Intake (TDFI); iii, TDFI and TDFR. 24-hour urine and tap water samples were collected from 216 children exposed to lower (n = 81), moderate (n = 72), or higher (n = 63) tap water F. ANOVA with Tukey's Test and Pearson's correlation were used to examine differences in mean DUFE and FUFE and relationships between variables. Mean drinking water F was 0.11(sd 0.17), 0.14 (sd 0.28) and 0.38 (sd 0.63) ppmF respectively. Differences (p water F; DUFE and TDFI, and; TDFI and TDFR. DUFEs of children drinking waters with 0.11 and 0.14ppm F, represented low F usage. The group drinking 0.38ppm F water represented optimal F usage. The weak significant positive association of DUFE with home tap water F suggests low validity for tap water F in estimating F exposure.

    Artificial intelligence (AI) techniques have increasingly become efficient alternative modeling tools in the water resources field, particularly when the modeled process is influenced by complex and interrelated variables. In this study, two AI techniques—artificial neural networks (ANNs) and support vector machine (SVM)—were employed to achieve deeper understanding of the salinization process (represented by chloride concentration) in complex coastal aquifers influenced by various salinity sources. Both models were trained using 11 years of groundwater quality data from 22 municipal wells in Khan Younis Governorate, Gaza, Palestine. Both techniques showed satisfactory prediction performance, where the mean absolute percentage error (MAPE) and correlation coefficient ( R) for the test data set were, respectively, about 4.5 and 99.8% for the ANNs model, and 4.6 and 99.7% for SVM model. The performances of the developed models were further noticeably improved through preprocessing the wells data set using a k-means clustering method, then conducting AI techniques separately for each cluster. The developed models with clustered data were associated with higher performance, easiness and simplicity. They can be employed as an analytical tool to investigate the influence of input variables on coastal aquifer salinity, which is of great importance for understanding salinization processes, leading to more effective water-resources-related planning and decision making.

    In the context of violations of human rights and insecurity, the Gaza Community Mental Health Programme (GCMHP) provides mental health services and psychosocial interventions that match local cultural and social norms. The GCMHP uses a community mental health approach to promote the psychological wellbeing of the people living in the Gaza Strip and advocate on mental health issues. The GCMHP provides preventive and therapeutic care to a broad public health spectrum of Gazan society. Services are provided in terms of preventative public health at the primary, secondary, and tertiary levels. Data reported here are from 2014-16. For primary prevention, our services include advocacy, public awareness, and media campaigns aimed at raising awareness about and preventing common mental disorders and behavioural difficulties in children. 35 878 people are estimated to have benefited from these programmes. The GCMHP also provides psychological first aid and crisis intervention to vulnerable persons and a free telephone counselling service. About 12 943 persons have received individual sessions, and 2590 persons have received telephone counselling. The GCMHP also provides training to enhance the skills of professionals of local organisations working in mental health and psychosocial services. 3557 people have attended these programmes. As secondary prevention, the GCMHP offers individual and group psychotherapy, and routine home visits are provided for torture survivors and individuals and families exposed to cumulative trauma. 11 713 individuals have received such services. As tertiary prevention, rehabilitation services including physiotherapy and occupational therapy are provided to help patients regain their role as active members of the community. 398 people have received these services. A public health-oriented approach to mental health services fits the socioecological model that locates individuals and families within the context of their community, religious

    Siege, a process of political domination aimed at isolating an entire population, is a unique threat to health-care provision. The aim of this study was to qualitatively examine the effects of the Israeli siege on the practices and systems that underlie health in the Gaza Strip. Data were from participant observation between 2009 and 2017, including 20 interviews with doctors and health administrators in non-governmental organisations (NGO), government, and UN sectors. All participants were provided with a description of the study and provided written consent to participate. The study was approved through the Human Subjects Review process at Bucknell University and the University of Washington. The data were analysed using a critical political economic framework, based on the concepts of primitive accumulation, accumulation by dispossession, surplus populations, and de-development. These analytical frames are further developed to interpret neoliberal trends in health-care systems organising and financing as they apply in the distorted social and economic context of siege. The elimination of political sovereignty through the twin processes of occupation and siege are the primary impediments to the successful promotion of public health in the Gaza Strip. Findings indicate that siege impinges on effective health-care provision by withholding materials and resources and undermining the health care at a systems level. These strains pose considerable threats to health care, within the ministry of health and among other entities in the Gaza Strip that deliver care. Gazan society is divested of the underpinnings necessary for a well functioning sovereign health-care infrastructure. Instead of a self-governing, independent system, this analysis reveals a system that is comprised of captive clients who are entirely dependent on Israel, international bodies, and the aid industry for goods and services, with no means of independent development. The siege represents a

    Twelve elements (Ag, Al, As, Cd, Ca, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were analyzed in 120 composite samples of influent and effluent wastewater; the results revealed that domestic wastewater influent contains considerable amounts of heavy metals and the partially functional treatment plants of Gaza are able to remove 40-70% of most metals during the treatment process. Heavy metals in 31 industrial wastewater effluents are within the ranges of international standards. All industries of Gaza are light, despite that they have no treatment facilities, their effluents are being discharged to municipal sewerage system and the existing treatment plants are capable to absorb the industrial effluents with no significant impact on treatment bioprocesses. Thirty parameters were determined in 35 sludge samples; P, AOX, C, S, CaCO{sub 3}, Mg, Ca, Na, K, Li, Cu, Zn, Ni, Pb, Mn, Fe, Cr, Co, Cd, As, Hg, Ti, Se, Br, Rb, Th, Sr, Y, U, and Zr. Although there are no treatment facilities for sludge within the treatment plants, the results indicated that sludge in general is clean of heavy metals. Zinc and AOX only showed anomalous concentrations; more than 85% of sludge samples showed that averages of zinc and AOX are 2000 mg/kg and 550 mg Cl/kg, respectively, which exceed the standards of all industrial countries for sludge to be used in land application.

    Abstract Objective To present data from a 2008 infant mortality survey conducted in Jordan, Lebanon, the Syrian Arab Republic, the Gaza Strip and the West Bank and analyse infant mortality trends among Palestine refugees in 1995–2005. Methods Following the preceding birth technique, mothers who were registering a new birth were asked if the preceding child was alive or dead, the day the child was born and the date of birth of the neonate whose birth was being registered. From this information, neonatal, infant and early child mortality rates were estimated. The age at death for early child mortality was determined by the mean interval between successive births and the mean age of neonates at registration. Findings In 2005–2006, infant mortality among Palestine refugees ranged from 28 deaths per 100 000 live births in the Syrian Arab Republic to 19 in Lebanon. Thus, infant mortality in Palestine refugees is among the lowest in the Near East. However, infant mortality has stopped decreasing in recent years, although it remains at a level compatible with the attainment of Millennium Development Goal 4. Conclusion Largely owing to the primary health care provided by the United Nations Relief and Works Agency (UNRWA) for Palestine Refugees in the Near East and other entities, infant mortality among Palestine refugees had consistently decreased. However, it is no longer dropping. Measures to address the most likely reasons – early marriage and childbearing, poor socioeconomic conditions and limited access to good perinatal care – are needed.

    To assess total and faecal coliform contamination in water wells and distribution networks over the past 7 years, and their association with human health in Khan Yunis Governorate, Gaza Strip. Historical data and interview questionnaire. Data were obtained from the Palestinian Ministry of Health on total and faecal coliform contamination in water wells and distribution networks, and on the incidence of water-related diseases in Khan Yunis Governorate. An interview questionnaire was conducted with 210 residents of Khan Yunis Governorate. Total and faecal coliform contamination exceeded the World Health Organization's limit for water wells and networks. However, the contamination percentages were higher in networks than in wells. Diarrhoeal diseases were strongly correlated with faecal coliform contamination in water networks (r=0.98). This is consistent with the finding that diarrhoeal diseases were the most common self-reported diseases among the interviewees. Such diseases were more prevalent among subjects who drank municipal water than subjects who drank desalinated or home-filtered water (odds ratio=2.03). Intermittent water supply, insufficient chlorination and sewage flooding seem to be associated with self-reported diseases. Residents in the Gaza Strip have a good level of knowledge about drinking water contamination, and this is reflected in good practice. Water quality has deteriorated in the Gaza Strip, and this may contribute to the prevalence of water-related diseases. Self-reported diseases among interviewees in Khan Yunis Governorate were associated with source of drinking water, intermittent water supply, insufficient chlorination, sewage flooding and age of water networks.

    This study aimed to assess the level of posttraumatic stress disorder and to examine the relationship between exposure to war stress and posttraumatic symptoms among health care providers following Israeli offensives against Gaza Strip in 2014. A cross-sectional design was used for this study. We targeted all nurses and doctors working in three governmental hospitals in the Gaza Strip and worked with victims of the last war, more specifically, those who were working in emergency departments, intensive care units, operating rooms, surgical departments, and burn units. A demographic sheet and Impact Event Scale-Revised were used in this study. The Impact Event Scale-Revised has three sub-scales; intrusion, avoidance, and hyper-arousal. The results showed that 291 (89.8%) of 324 participants had scores more than 35 (threshold cut-off point) on the Impact Event Scale-Revised. Scores ranged from zero to 80 with a mean of 52.13. Females had higher levels of stress (55.79) than males (51.63) and nurses (54.85) had more stress than physicians (47.38). The most frequent symptoms of trauma subscales was "avoidance" (mean=20.04), followed by "intrusion" (mean=17.83), and then "hyper-arousal" (mean=14.27). Levels of trauma symptoms were not affected by place of living, hospital of work, while level of education had impacted level of trauma. The findings showed that health care providers suffered from severe posttraumatic symptoms after exposure to prolonged war stress. This level of trauma among health care providers warrants intervention programs to reduce stress and trauma among Gaza health care providers after the war. Copyright © 2015 Elsevier Inc.

    The second (Al-Aqsa) intifada (Arab violent uprising) which erupted across Israel in 2000 eventually led the Israel Defense Forces to deploy armored tracked vehicles (ATVs) (tanks, armored personal carriers, and D-9 bulldozers) within Israel's agricultural periphery of the Gaza Strip, following daily attempts by Arab terrorists and guerillas to penetrate Israel. Combat movement of the ATVs was mainly concentrated to dirt roads, between agricultural fields, wherever possible. As a result of semi-arid Mediterranean (climate) winter rains, annually averaging 250 - 350 mm, it was reported that ATVs often sank in muddy terrain. This study investigated what caused ATVs to sink. The main data collected concerning the types of vehicles that sank related to: land-use characteristics, soil type, and daily rainfall. Interviews with commanders were also conducted for additional details. Between the fall and spring, surveys and weekly / bi-weekly field soil cone penetrometer tests were conducted at ten sites with different pedological and land-use characteristics. The loess soils, especially in agricultural fields, were generally found to be conducive to ATV traffic, even shortly after rainstorms of 10-30 mm. However, following several rainfall events exceeding 10 mm, ATVs and tanks regularly sank into local topographic depressions in the undulating landscape. These consisted of short segments of dirt roads where runoff and suspended sediment collected. After the early rains in late fall, tank ruts fossilize and become conduits of concentrated runoff and fine particles eroded by ATV activity during the summer months. Tank track ruts that formed in mud, compacted the soil, drastically altered drainage patterns by directing significant surface flow, and suspended sediment into these depressions, creating "tank-traps" whose trafficability ranged from "untrafficable" to "trafficable with constraints." This study shows that intense, routine, defensive military activity operated

    Full Text Available Shoulder pain among paraplegic persons has negative effects on their lives. The prevalence of shoulder pain among persons with spinal cord injury (SCI varies from 30% to 70% in different studies and may be related to repetitive use of the shoulder during self-care and wheelchair-related activities. Purpose: This study focused on the prevalence of shoulder pain and examined its effects on activities of daily living and social participation, and on functional, work and recreational or athletic activities. It also aimed to detect the degree of satisfaction with shoulder functioning wheelchair users who were paraplegic due to  spinal cord injury, in the Gaza strip.  Methods: Cross sectional study design was used to collect data from 80 persons with paraplegia, post rehabilitation, who were still using manual wheelchairs (MWC for ambulation. After giving informed consent, the selected persons were interviewed directly in their homes, and filled questionnaires which included the demographic data, Wheelchair User’s Shoulder Pain Index (WUSPI and Shoulder Rating Questionnaire (SRQ.Results: The prevalence rate of shoulder pain among paraplegics who use manual wheelchairs was 62%. Pushing a wheelchair for 10 minutes or more, and propulsion up ramps or inclines outdoors were the most common activities that caused and exacerbated shoulder pain. Sixty four percent from among the study sample mentioned that they had no limitation in shoulder-using ability during daily personal and household activities, while the rest experienced different degrees of limitation. Seventy-four percent reported no limitation during recreational or athletic activities, while the rest (26% agreed that pain has variably limited their participation in these activities. Fourteen percent from the sample rated the overall degree of satisfaction with their shoulder functioning as fair, and the rest rated their satisfaction from good to excellent.Conclusion: Shoulder pain, ranging

    Metabolic syndrome (MetS) which is a multifaceted syndrome, has been demonstrated as a common precursor for developing cardiovascular diseases and/or type 2 diabetes mellitus. Different diagnostic definitions for MetS have been proposed and recommended. We set up to evaluate the reliabilities of the National Cholesterol Education Program's Adult Treatment Panel III (NCEP/ATP III) and the International Diabetes Federation (IDF) definitions in diagnosing MetS among Gaza Strip Palestinians. This cross sectional study involved a randomly selected two hundred and thirty apparently healthy adults from the Gaza Strip. Anthropometric measurements, blood pressure, fasting plasma glucose, lipid profile, and questionnaire interviews were performed. The overall prevalence of MetS in our Gaza Strip cohort was 23.0% and 39.5% according to NCEP/ATP III and IDF definitions respectively (pdefinition (mean 3.42 ± 0.63 vs 3.52 ± 0.69 respectively, p=0.865). Both IDF and NCEP/ATP III showed an increased prevalence of MetS with age, and body mass index (BMI), however they revealed different prevalence trends with sex. Except for BMI, there were no significant differences in the general and metabolic related characteristics between subjects with MetS of IDF and NCEP/ATP III definitions. Independently of the definition used, MetS is highly prevalent in Gaza Strip population, with a steady increase in MetS prevalence through age and BMI. The IDF definition tends to give higher values for MetS prevalence, and therefore could be more appropriate for diagnosing MetS in Gaza Strip cohort. Copyright © 2012 Diabetes India.

    Full Text Available Abstract: This article deals with analyzing the place and the political Islam occupies on the Palestinian territories. The author tries to prove that despite the “Arab spring” and growing popularity of Islamism in the neighbor Arab countries its popular support among Palestinians is low. The main reason for this is Israeli total control of political, economic and - partially - social processes taking place in the West Bank. Position of the officials in Ramallah who together with Tel-Aviv strictly contain spread of Islamism throughout the West Bank also has a strong suppressing effect. Central Palestinian leadership may be called one of the few secular political establishments that are still in power in the Arab countries. The main explanation for this is the desire to make a positive effect on the international community, which Palestine totally depends on in political and financial terms. Also one should keep in mind secular beliefs of the current political elite in Palestine. President Mahmoud Abbas with his counterparts from FATAH and PLO represent old type of Arab nationalist politicians, almost all of who were stripped from power after the beginning of “Arab spring” in 2011. Finally, Palestinian society itself still feels united by the idea of national liberation from the Israeli occupation. This helps Palestinians to put aside the issue of religious self-identification. According to the surveys, most of Palestinians still rank their national identity number while describing their identity, while religion comes only second (despite the strong stable tendency for growing Islamization of their views. The only Palestinian enclave where political Islam has gained ground is isolated Gaza Strip. However ruling there “Islamic Resistance Movement” (HAMAS, despite declared anti-Zionism and Islamism, in reality show pragmatic readiness for certain coordination of its actions with Israel and central government in Ramallah.

    Full Text Available Abstract Background There is growing recognition of the psychological impact of adversity associated with armed conflict on exposed civilian populations. Yet there is a paucity of evidence on the value of mental health programs in these contexts, and of the chronology of psychological sequelae, especially in prolonged conflicts with repeated cycles of extreme violence. Here, we describe changes in the psychological profile of new patients in a mental health program after the military offensive Cast Lead, in the context of the prolonged armed conflict involving the Gaza Strip. Methods This study analyses routinely collected program data from a Médecins Sans Frontières mental health program in the Gaza Strip spanning 2007–2011. Data consist of socio-demographic as well as clinical baseline and follow-up data on new patients entering the program. Comparisons were made through Chi square and Fisher’s exact tests, univariate and multivariate logistic and linear regression. Results PTSD, depression and other anxiety disorders were the most frequent psychopathologies, with 21% having multiple diagnoses. With a median of nine sessions, clinical improvement was recorded for 83% (1122/1357, and more common for those with separation anxiety, acute and posttraumatic disorders as principal diagnosis (855/1005, compared to depression (141/183, p Conclusion Evolving changes in patient volume, diagnoses and recall period to triggering events suggest a lengthy and durable effect of an intensified exposure to violence in a context of prolonged conflict. Our findings suggest that mental health related humanitarian relief in protracted conflicts might need to prepare for an increase in patients with changing profiles over an extended period following an acute flare-up in violence.

    The sustainable management of waste requires a holistic approach involving a range of stakeholders. What can often be difficult is to understand the manner in which different types of stakeholder networks are composed and work, and how best to enhance their effectiveness. Using social network analysis and stakeholder analysis of healthcare waste management stakeholders in the case study region of the Gaza Strip, this study aimed to understand and examine the manner in which the networks functioned. The Ministry of Health was found to be the most important stakeholder, followed by municipalities and solid waste management councils. Some international agencies were also mentioned, with specific roles, while other local institutions had a limited influence. Finally while health-care facilities had a strong interest in waste management, they were generally poorly informed and had limited links to each other. The manner in which the networks operated was complicated and influenced by differences in perception, sharing of information, access to finance and levels of awareness. The lack of a clear legal framework generated various mistakes about roles and responsibilities in the system, and evidently regulation was not an effective driver for improvement. Finally stakeholders had different priorities according to the waste management issues they were involved with, however segregation at the source was identified as a key requirement by most. Areas for improving the effectiveness of the networks are suggested. The analysis utilized an innovative methodology, which involved a large number of stakeholders. Such an approach served to raise interest and awareness at different levels (public authorities, health providers, supporting actors, others), stimulate the discussion about the adoption of specific policies, and identify the effective way forward.

    Maternal exposure to environmental tobacco smoke (ETS) is a major health hazard as it contains lower doses of the toxins that smokers' inhale. Prenatal exposure to wood fuel smoke has been linked to delivering low birth weight (LBW) infants. The study aims to assess the association between prenatal exposure to ETS and wood fuel smoke and LBW. A case-control study in ratio 1:1 was conducted in two hospitals with obstetric services in Gaza Strip. Subjects were selected during May-June and July-August 2007 from attenders of Mbarak Hospital and Shifa Medical Centre, respectively. 184 (41.2%), and 79 (17.7%) out of 446 participants were exposed to environmental tobacco smoke and wood fuel smoke, respectively. Adjusted maternal exposure to ETS (especially the number of cigarettes smoked, water pipe and wood fuel smoke) was associated with LBW infants. Cigarette smoke exhibits an independent dose-response risk of LBW after adjusting for confounders. Prenatal exposure to cigarette smoke indoors is related to a reduction in birth weight of infants of -237 g (95% CI: -415, -58) for pregnant women exposed to 1-20 cigarettes per day and -391 g (95% CI: -642, -140) for exposure to more than 20 cigarettes per day. Exposure to wood fuel smoke exhibits a reduction of infants' adjusted mean birth weight by -186 g (95% CI: -354, -19). Prenatal exposure to passive smoking and wood fuel smoke are independently associated with LBW. Both these factors are modifiable exposures that could possibly lead to a reduction of delivering LBW infants.

    2010-11-01

    Full Text Available In 1996, Osama bin Laden declared jihad against the American forces occupying Saudi Arabia, calling for Muslims to expel the infidels from the “land of the two holy places.” The first sacred ground mentioned in this statement, however, was not Saudi Arabia but Palestine. His words seething with hatred, bin Laden scorned the Arab regimes for failing to recapture Jerusalem and described the situation as a festering wound upon the Islamic 'umma'.[1] Fourteen years later, even after orchestrating devastating attacks in three Western capitals, Bin Laden’s al-Qaeda is still unable to do much against Israel besides issuing scathing diatribes. Its most vigorous efforts to establish itself in the Palestinian arena have been in the Gaza Strip. Here, however, al-Qaeda-linked groups are stymied by a perhaps surprising adversary: Hamas. But despite Hamas’s efforts to suppress them, 'Salafi'-jihadi groups maintain an underground presence. Even if al-Qaeda affiliates remain weak operationally in comparison to Hamas, al-Qaeda’s ideology of global jihad seems to be on the rise in Gaza. Meanwhile, the al-Qaeda leadership is relentless in pursuing new and ingenious ways for its agents to penetrate the Strip. A Hamas weakened by a tightened blockade or another war with Israel would leave an opening for 'Salafi'-jihadi militants. The prospect of these al-Qaeda-linked factions upsetting a fragile peace needs to be considered among the many other factors relevant to engagement with Hamas.

    Full Text Available The primary aim of this paper is to identify the skills that both construction clients and contractors identify as critical to improving the building sector’s overall productivity in the Gaza Strip, Palestine. Through a comprehensive questionnaire targeting key project stakeholders (namely, clients and contractors, this paper also evaluates the factors affecting skills upgrade and the continuity of training approaches currently used in this sector. Mentoring appears to be the preferred training approach for clients and contractors alike. According to respondents, decision-making, problem solving and goal setting skills are highly critical. Furthermore, conventional face-to-face meetings were identified as the most suitable communication channel to obtain and exchange project information. Staff self-interest and willingness to upgrade their skills were ranked as the most important factors influencing the effectiveness of the professional training process. Based on the study findings, the paper concludes with a set of practical recommendations.

    The atrocities in Syria have been covered in the four general medical weekly journals in the USA and the UK. Medical journal articles addressing political determinants of public health have rightly described and criticised the international community's failure to enforce humanitarian law while urging global bodies of power to ensure protection of civilians and civilian infrastructure and medical services. Discussions of the political influences on health of people in the occupied Palestinian territory (West Bank and Gaza Strip) seem to be considered politically out-of-bounds by some medical journals. This study used a keyword-based search to explore patterns of publication about the occupied Palestinian territory and Israel by four large US and European medical journals. The four highest ranked, peer-reviewed, international medical journals were searched: The Journal of the American Medical Association (JAMA), The New England Journal of Medicine (NEJM), The Lancet, and The British Medical Journal (BMJ). Searches were conducted between Sept 1 and Sept 6, using each journal's search engine with the keywords "Gaza", "West Bank" and the stems "Palestin*" and "Israel*" in all fields for the period Jan 1, 1990, to Sept 6, 2016. News and commentary articles were included in the findings. The searches found the term "Palestin*" in 49 articles from the two US journals (32 in JAMA; 17 in NEJM) and 694 articles in the two UK journals (236 in The Lancet; 458 in BMJ). "Israel*" was found in 840 articles in US journals (386 in JAMA; 454 in NEJM) and in 2972 articles in UK journals (1388 in The Lancet; 1584 in BMJ). "West Bank" was found in nine articles in US journals (nine in JAMA; none in NEJM) and in 297 articles from the UK (211 in The Lancet; 86 in BMJ). "Gaza" was found in 18 articles in US journals (15 from JAMA; three from NEJM) and in 487 articles in UK journals (324 in The Lancet; 166 in BMJ). Compared with the two US-based medical journals, the UK journals published

    The goal of the study was to determine the long-term prevalence of combat-related treatment seeking and posttraumatic stress disorder (PTSD) in Israel's veterans deployed to the Second Lebanon War (2006) and "Operation Cast Lead" in the Gaza Strip (2009). The prevalence of treatment seeking and DSM-IV-TR diagnoses among Israel Defense Force (IDF) veterans was assessed using seven and five year's surveillance and records. The whereabouts and combat exposure of veterans during the war was determined based on the IDF's Operations Directorate records. Overall prevalence of treatment seeking was 1.32% and 0.38% in the Second Lebanon War and "Operation Cast Lead", respectively. The prevalence of treatment-seeking veterans from the Second Lebanon War and in "Operation Cast Lead" was significantly higher in soldiers deployed to high combat-exposure zones (2.19% and 3.1%, respectively), relative to low combat-exposure zones (0.24% and 0.06%, respectively), and relative to soldiers deployed elsewhere (0.26% and 0.02%, respectively). PTSD prevalence was similar among treatment-seeking veterans deployed in high combat-exposure zones in both combats. There is a gap of anywhere between 3% and 11% between treatment seeking by IDF veterans following war deployment and the actual prevalence of PTSD in this soldier population.

    The state formation process in Palestine started after the Oslo agreements between Israel and Palestine in 1994, which established a Palestinian quasi-state. The process came, however, to an almost complete halt with the onset of the second intifada in late 2000 and definitely with the Israeli reoccupation of the West bank and Gaza in 2002. At the time of writing, Palestine is divided into eight zones, with 120 checkpoints and 220 enclaves, a wall is being built, the economy is in ruins and t...

  7. Advocating change in Palestine. Advocacy for reproductive health: Palestine.

    1996-01-01

    The Palestinian Family Planning and Protection Association (PFPPA) recently implemented a new strategic plan based on the Strategic Plan of the International Planned Parenthood Federation (IPPF) aimed at the empowerment of women. Advocacy is the central part of the program with preparing the services and dealing with the issue of population. In early 1995 a round of meetings in the West Bank and the Gaza Strip launched the plan with new programs for women, youth, men, information, education, and communication, and service provision to start in January 1996. In Gaza the Youth Program is well under way. Five members were selected from each of 50 groups for a 1-week training course in Gaza City in November 1995. The topics included: mutual respect between husband and wife, discussion of the role of family planning in the context of Islam, the rights and wrongs of polygamy, and the hotly debated issue of sex segregation in education. The PFPPA staff was initially apprehensive about the new youth and women's program plans to broaden family planning to women's empowerment and sexual and reproductive health. An IPPF-sponsored video was also shown in Hebron, West Bank, on the problem of early marriage. It featured Palestinian women: one with 12 children who was married at age 13; a mother whose husband wanted to marry off their 12-year-old daughter; and portrayed pressure from husbands and other family members to produce many children. The new strategy engendered debate in the West Bank and Gaza among village women and young people, while in the meantime the training of government health workers started in sexual and reproductive health counseling. In the village of Tkooi, near Bethlehem, a counselor held sessions on the oppression of women and psycho-physiological problems and stress. A lawyer also summarized women's economic and property rights, which most of them were unaware of.

    Liquefied petroleum gas (LPG) is widely used in the Gaza Strip for domestic purposes, in agriculture and industry and, illegally, in cars. This study aimed to identify possible health effects on workers exposed to LPG in Gaza governorates. Data were collected by a questionnaire interview, and haematological and biochemical analyses of venous blood samples were made from 30 workers at filling and distribution stations and 30 apparently healthy controls. Statistically significant differences were found in all self-reported health-related complaints among LPG workers versus controls. LPG workers had significantly higher values of red blood cell counts, haemoglobin, haematocrit mean corpuscular haemoglobin and platelet counts. They also had significantly higher values of kidney function tests (urea, creatinine and uric acid) and liver function enzyme activities (aspartate aminotransferase and alanine aminotransferase). LPG workers at Gaza Strip petroleum stations are at higher risk for health-related symptoms and clinical abnormalities.

    2017-08-01

    Palestinian neurosurgery started with Dr. Antone Tarazi as the first Palestinian neurosurgeon. Before that, there was no organized neurosurgery specialty, and general surgeons performed neurosurgical procedures. Here we review the history of neurosurgery and neurosurgical applications in Palestine, evaluate some limitations of the current system, and discuss major challenges to improving this system. We collected information from various sources in either English or Arabic. The development of neurosurgery and neurosurgical training in Palestine began in 1960 with the first center established in Jerusalem, which provided much-needed neurosurgical services and training in the fields of neurosurgery and neurology. Palestine has produced a number of its own neurosurgeons and has promoted further progress by establishing the Palestinian Neurosurgical Society in 2014. Today, there are 34 neurosurgeons (including 1 female neurosurgeon) and 17 residents providing expert care in 17 centers across Palestine, along with 1 neurosurgical residency program. Neurosurgery in Palestine has faced many challenges, some of which have been overcome. However, there remain many challenges, which will require much time and effort to surmount. Political stabilization is a significant factor in the progress of neurosurgery in Palestine. Copyright © 2017 Elsevier Inc. All rights reserved.

    During four separate Israeli military attacks on Gaza (2006, 2009, 2012, and 2014), about 4000 Palestinians were killed and more than 17 000 injured (412 killed and 1264 injured in 2006; 1383 killed and more than 5300 injured in 2009; 130 killed and 1399 injured in 2012; and 2251 killed and 11 231 injured in 2014). An unknown number of people had traumatic amputations of one or more extremities. Use of unmanned Israeli drones for surveillance and armed attacks on Gaza was evident, but exact figures on numbers of drone strikes on Gaza are not available. The aim of this study was to explore the medical consequences of strikes on Gaza with different weapons, including drones. We studied a cohort of civilians in the Gaza Strip who had one of more traumatic limb amputation during the Israeli military attacks between 2006 and 2016. The study was done at The Artificial Limb and Polio Center (ALPC) in the Gaza Strip where most patients are treated and trained after amputation. We used standardised forms and validated instruments to record date and mechanism of injury, self-assessed health, socioeconomic status, anatomical location and length of amputation, comorbidity, and the results of a detailed clinical examination. The studied cohort consisted of 254 Paletinian civilians (234 [92%] men, 20 [8%] women, and 43 [17%] children aged 18 years and younger) with traumatic amputations caused by different weapons. 216 (85%) people had amputations proximal to wrist or ankle, 131 (52%) patients had more than one major amputation or an amputation above the knee, or both, and 136 (54%) people were injured in attacks with Israeli drones, including eight (40%) of the women. The most severe amputations were caused by drone attacks (p=0·0001). Extremity injuries after drone attacks led to immediate amputation more often than with other weapons (p=0·014). Patients injured during cease-fire periods were younger than patients injured during periods of declared Israeli military

  18. A SUSTAINABLE APPROACH FOR URBAN INTEGRATION OF HAMM M SAM RAH IN THE HISTORIC CITY OF GAZA

    Directory of Open Access Journals (Sweden)

    Nihad Almughany

    2009-03-01

    Full Text Available Throughout historical ages, Gaza has been viewed amongst the most important cities of Palestine. The historic centre of Gaza is among the most important sites in the city as it bustles with business activities and is the place of major historic sites, and cultural and architectural legacy in the region. The city of Gaza used to have several public baths which were built to meet the hygiene and health needs of the local inhabitants. Furthermore, they played an important social role as gathering places for socio-cultural events, parties and meetings. It is most unfortunate that a large number of these baths have disappeared, apart from the Samarah bath in Al Zaitoun neighbourhood at the heart of the old city. Hence, the preservation of this unique genuine heritage building is of high importance. This paper attempts to establish key scenarios to integrate the hammām into the Old City urban fabric. The study is based on the hypothesis stating that a sustainable approach can be achieved by associating the hammām to its urban context. Thus, the hammām will constitute an important part of a touristic tour including the main urban entities composing the old City: Al-Omari Mosque, Qisaria Market, Pasha Palace and Khan Al- Zait. Three main scenarios will be proposed, analyzed and explored. The study concludes by suggesting an appropriate scenario for the adaptive re-use of the building, in order to preserve the hammam.

    Full Text Available In clinical practice, physicians have recently attempted to avoid mechanical ventilation (MV as much as possible and have started to use non-invasive ventilation (NIV in patients with respiratory failure. A prospective observational study was conducted to assess the applicability, effectiveness, and safety of NIV in managing patients with respiratory failure in Palestine. Fifty-two patients (39 patients from West Bank and 13 patients from Gaza Strip who fulfilled criteria for inclusion were admitted to the two medical care units of the An-Najah National Teaching Hospital during a 10-month period. These patients formed the study population to receive NIV. The results came with baseline (mean ± SD pH, PaO2, and PaCO2 measurements of 7.36 ± 0.1, 75.62 ± 32.7, and 46.5 ± 20.86 mmHg, respectively. The primary indication for NIV was hypoxemic respiratory failure (n = 38, 73%. The success rate with NIV was 78%, with 40 out of 52 patients weaned successfully. Significant improvements were observed in the first hour following institution of NIV in pH (7.38 ± 0.07, P < 0.001, PaO2 (90.4 ± 52.4, P < 0.001, and PaCO2 (40.4 ± 12.6, P < 0.001. These physiological parameters continued to improve up to the time of weaning: pH (7.39 ± 0.07, P < 0.001, PaO2 (99.9 ± 44.3, P < 0.001, and PaCO2 (38.6 ± 13.9, P < 0.001. The parameters were maintained within 12 h post-weaning: pH (7.39 ± 0.08, P < 0.001, PaO2 (97 ± 30.3, P < 0.001, and PaCO2 (36.9 ± 10.3, P < 0.001. This study has shown benefits of NIV in avoiding the call for invasive MV in patients exhibiting respiratory failure of varied etiology, with similar results comparable to previous studies in developed countries. Thus, increased usage of NIV in respiratory failure is likely to affect favorably in countries with limited resources such as Palestine.

    Yakubu Ozohu-Suleiman

    2015-07-01

    Full Text Available It is often assumed that local media are a potential deescalating tool in global conflict. This study examines how four leading newspapers in Southeast Asia (Star of Malaysia, Philstar of the Philippines, Jakarta Post of Indonesia, and The Nation of Thailand reported the Israeli-Palestinian conflict during the year after the 2009 Gaza War. A census of 536 reports was coded for tones (to detect alignment, frames (to detect characterization of the conflict, and sources (to examine correlation with coverage tones. The results show fragmented alignment of the newspapers with Palestine and Israel. Conflict frames on offensives, fighting, threats, military strategies, demonization, death, and destruction were most prevalent. Coverage tones were significantly correlated with sources, suggesting that the potential of local media to serve as deescalating tools in global conflicts is subject to the varying political contexts in which they operate in relation to specific conflicts.

  7. Offshore tsunami deposits signify risk for heavily populated southern Levant Coastline (Gaza and Ashkelon)

    The southern Levantine coastline is exposed to a variety of potential tsunami-generating sources, including far field influences such as large earthquakes and volcanic eruptions as well as near field offshore landslides along the continental slope, where slumping features are present throughout the area. Not only does this coast boast a long history of continuous occupation but also today large cities (e.g. Tel Aviv, Ashdod, Ashkelon, and Gaza) and related critical infrastructure such as ports, power plants, chemical industries, roads, etc. are located along this corridor. In addition, further to the south, the Gaza Strip has one of the highest population densities in the world and is dependent on external assistance for many basic needs, goods and infrastructure. Newly obtained sediment cores from the shallow shelf offshore Ashkelon (~12 km north of Gaza City) exhibit several events that can be linked to historical records. These cores can be subdivided in two general horizon types that show relative changes to one another across different proxies. The continuous input of Nile-delta sands results in a homogenous and stable 'background' sediment represented by well sorted, finer sands, few inclusions, lower proportions of A. parkinsoniana relative to fossil tests, and very few yellow-stained and blackened specimens. Contrasting these normal marine condition deposits are high energy tsunamigenic deposits characterized by poor sorting, with inclusions of a range of whole, articulated, and fragmented shells, wood, charcoal, and sub-angular to rounded pebbles. Newly mapped and quantified offshore bathymetric evidence for landslides and slumping motion has identified features that are large enough to generate tsunamis that would affect the study area. These were modeled as possible sources and compared to different far field events. Some of those tsunamigenic horizons could be assigned to specific events ranging between the youngest at 1202AD to the oldest prehistoric

  8. Crisis of Legitimacy in Palestine

    2016-04-01

    Full Text Available Abstract: Palestinian society is geographically separated and politically fragmented. This is attributed to partisan affiliation and alignment, absence of conceptual and professional framework of civil society, unethical approach of Palestinian political leaders, and unconstitutional political institutions. Such polarization and division have created political antagonism within elites and between factions. The broad objective of this research is to investigate the legitimacy crisis in Palestine, the current political dilemma in the Palestinian Authority, and the public response to the situation. The research introduces direct and thorough understanding of the developing political context surrounding these issues; taking into consideration that growing deficit in legitimacy could create potentially dire consequences, particularly if present trends on the ground continue. The research promotes an analytical perspective based on legitimacy theory and exploring recent public opinion polls. This study formulates a constructive analysis of the failure of the Palestinian political institutions at the leadership level to meet the basic expectations of the Palestinian people and the unproductive methodology of hampering the implementation of the Basic Law concerning the Palestinian political system. It reviews the empirical dilemmas of the Palestinian Authority and eliminates several assumptions of Fatah and Hamas’s - main parties - political and domestic priorities. The possibility of a new Palestinian political phenomena emerging is in the context of a new popular mobilisation lessened by the fact that both movements (Fatah and Hamas are firmly enmeshed in the very fabric of Palestinian society through patronage networks.

This study builds on existing research on war-related factors that may affect health-care staff by particularly focusing on trauma exposure in both professional and everyday life, as well as on correlates of later positive psychological changes. What this paper adds to existing knowledge? It shows that one in five nursing staff working in Gaza experienced post-traumatic stress symptoms within the clinical range, 2 years after an incursion on Gaza and after being exposed to substantial trauma during this period. Participants appeared to develop a variety of post-traumatic growth responses following trauma exposure. Although nurses experienced traumatic events both as civilians and in their health-care capacity, personal exposure was strongly associated with PTSD symptoms. What are the implications for practice? Support to nursing and other health-care professionals in war situations should entail different levels, remain available well after an acute conflict, and take into consideration both personal and practice-related traumatic events. Mental health nursing practitioners can play a pivotal role in this. To establish the association between war traumatic experiences, post-traumatic stress disorder (PTSD) symptoms and post-traumatic growth among nurses in the Gaza Strip, 2 years after an incursion on Gaza, and during a period of ongoing trauma exposure. This study builds on existing evidence by considering exposure to personal and work-related traumatic events, and on factors associated with later positive psychological adaptation. The sample consisted of 274 randomly selected nurses in Gaza who completed the Gaza Traumatic Events Checklist, PTSD Checklist, and Posttraumatic Growth Inventory. Of the nurses, 19.7% reported full PTSD. There was a significant relationship between traumatic events and PTSD scores; as well as between community-related traumatic events and post-traumatic growth. Participants reported a range of traumatic

    Motivated by the problem of finding an explicit description of a developable narrow Moebius strip of minimal bending energy, which was first formulated by M. Sadowsky in 1930, we will develop the theory of elastic strips. Recently E.L. Starostin and G.H.M. van der Heijden found a numerical description for an elastic Moebius strip, but did not give an integrable solution. We derive two conservation laws, which describe the equilibrium equations of elastic strips. In applying these laws we find...

Considérant qu'elle s'inscrit dans une logique israélienne consistant à tout mettre en œuvre pour repousser sine die tout accord sur le fond avec les Palestiniens, il suggère que la force réelle ou alléguée de Hamas est utilisée par le gouvernement israélien pour justifier auprès de la communauté internationale en termes de lutte contre le terrorisme une politique en réalité visant à détruire toute institutionnalisation du nationalisme palestinien.This article is an attempt to explore new schemes for the full understandig of what was the challenge in the last war in Gaza’s Strip. Between December 27th and January 21st nothing less than 1330 people died while 5450 others remained injuried on the Palestinian side. Ten Israeli soldiers and three civilians died in the meantime. This article is an interpretation of the Israeli way of managing the image of the Palestinian resistance movment in years, through the Muslim Brothers, FATHA, and now Hamas, as a danger for democracy and the western world. The figure of the trouble maker is used in order to justify a long term conflict which end Israel is the only country capable to put an end to.

    Disease severity scores such as CURB-65 are often used to guide the management of patients with community-acquired pneumonia. Early and adequate empirical antibiotic treatment reduces mortality. The aim of this study was to examine the severity assessment and management of patients presenting with community-acquired pneumonia at the European Gaza Hospital in the Gaza Strip and to compare this to the best available evidence. Medical records of all patients admitted to the European Gaza Hospital with a diagnosis of community-acquired pneumonia between Dec 1, 2015, and March 31, 2016, were reviewed retrospectively. Clinical practice was compared with recommendations for severity assessment and the management of community-acquired pneumonia, as reported in guidelines by the National Institute for Health and Care Excellence and the American Thoracic Society. Ethical approval was obtained from the General Directorate of Human Resources. 141 patients were admitted to the European Gaza Hospital with community-acquired pneumonia during the study period. Records of 41 patients were missing or could not be retrieved. The mean age of patients was 55·9 years (SD 20·2). Blood urea and nitrogen concentrations were not documented for 48 (48%) patients, and respiratory rate was not documented for 73 (73%) patients. The CURB-65 score was determined only for 12 (12%) patients. Microbiological testing was done only for two (2%) patients. Although 18 different antibiotic regimens were used, 81 (81%) patients received a β-lactam plus macrolide combination therapy, either given alone (49 [49%] patients) or with another antibiotic (32 [32%] patients), which is in line with the recommendations for patients admitted to hospital with community-acquired pneumonia. 43 (43%) patients received anti-viral drugs, and 41 (41%) patients received corticosteroids. Clinicians were poorly adherent to current standards of care in severity assessment and management of community-acquired pneumonia

  15. Ionic and isotopic ratios for identification of salinity sources and missing data in the Gaza aquifer

    2006-03-01

    Groundwater is the only source of fresh water in the Gaza Strip. However, it is severely polluted and requires immediate effort to improve its quality and increase its usable quantity. Intensive exploitation of groundwater in the Gaza Strip over the past 40 years has disturbed the natural equilibrium between fresh and saline water, and has resulted in increased salinity in most areas. Salinization in the coastal aquifer may be caused by a single process or a combination of different processes, including seawater intrusion, upconing of brines from the deeper parts of the aquifer, flow of saline water from the adjacent Eocene aquifer, return flow from irrigation water, and leakage of wastewater. Each of these sources is characterized by a distinguishable chemistry and well known isotopic ratios. In this paper Na/Cl, SO 4/Cl, Br/Cl, Ca/(HCO 3+SO 4), and Mg/Ca ionic ratios were used to distinguish different salinization sources. δ11B and 87Sr/ 86Sr isotopic composition were also included in the model to study their importance in this monitoring task. The task of monitoring and the associated decision making process are characterized by a high degree of uncertainty with respect to input data and accuracy of models. For this reason, probabilistic expert systems, and more specifically, Bayesian belief networks (BBNs) are used to identify salinization origins. The BBN model incorporates the theoretical background of salinity sources, area-specific monitoring data that are characteristically incomplete in their coverage, expert judgment, and common sense reasoning to produce a geographic distribution for the most probable sources of salinization. The model is also designed to show areas where additional data on chemical and isotopic parameters are needed.

  19. A Simulation/Optimization approach to manage groundwater resources in the Gaza aquifer (Palestinian Territories) under climate change conditions

    The Gaza aquifer is the main source of water for agricultural, domestic, and industrial uses in the Gaza Strip. The rapid increase on water demand due to continuous population growth has led to water scarcity and contamination by seawater intrusion (SWI). Furthermore, current projections of future climatic conditions (IPCC, 2007) point to potential decreases in available water, both inflows and outflows. A numerical assessment of SWI in the Gaza coastal aquifer under climate induced changes has been carried out by means of the CODESA-3D model of density-dependent variably saturated flow and salt transport in groundwaters. After integrating available data on climatology, geology, geomorphology, hydrology, hydrogeology, soil use, and groundwater exploitation relative to the period 1935-2010, the calibrated and validated model was used to simulate the response of the hydrological basin to actual and future scenarios of climate change obtained from different regional circulation models. The results clearly show that, if current pumping rates are maintained, seawater intrusion will worsen. To manage sustainable aquifer development under effective recharge operations and water quality constraints, a decision support system based on a simulation/optimization (S/O) approach was applied to the Gaza study site. The S/O approach is based on coupling the CODESA-3D model with the Carroll's Genetic Algorithm Driver. The optimization model incorporates two conflicting objectives using a penalty method: maximizing pumping rates from the aquifer wells while limiting the salinity of the water withdrawn. The resulting coastal aquifer management model was applied over a 30-year time period to identify the optimum spatial distribution of pumping rates at the control wells. The optimized solution provides for a general increase in water table levels and a decrease in the total extracted salt mass while keeping total abstraction rates relatively constant, with reference to non

    For the last two centuries, Palestinian territory had faced several changes. This is due to historical precedents and the unstable political situation in the area. This has resulted in mutli-faced challenges in Palestine. The objective of this paper is to analyse and understand the major factors that had impacted the urban planning, urban form and urban development of the Palestinian territory. The findings showed that the lack of available land, rapid urban population growth, failure in urban planning policy decisions, the unstable political situation on the ground, fragmented urban developments in the west bank area, and also diffusion of urban sprawls within the landscapes and around the cities are the major factors that caused challenges in Palestine’s cities.

    Palestine receives good solar radiation throughout the year. The orientation of a solar collector (SC) in space is the primary factor influencing the quantity of absorbed solar radiation energy. By maximizing the optimal angles of a solar collector, the maximum of solar radiant energy will be achieved. This paper discussed a study that presented a new design idea of a one axis two position manual tracking photovoltaic (PV) system and demonstrated the enhancements on the optimum design. The purpose of this study was to provide technical information about tilt angle and orientation of PV panels for architects who are interested in building integrated photovoltaic (BIPV) systems and practitioner engineers who are interested in the utilization of renewable energy to enhance the efficiency of PV systems while reducing costs. The optimum tilt angle was determined mathematically. The optimum tilt angle depends on the geographical position and on the investigation period when the position of a solar collector will be stationary. The paper presented a case study on the lighting Gaza Valley project, which involved the re-design and re-evaluation for orientation and tiling of a previous design. It was concluded that power generation could be increased by 17 percent of the previous design, and can be increased by 3 percent of the optimum design without any additional cost. 12 refs., 3 tabs., 14 figs.

    Full Text Available Through some extremely difficult experiences, education in general and Higher Education in particular has remained a constant focus of resources in Palestine.  Due to the ongoing occupation of Palestine, Palestinian universities could not expect to contribute significantly to economic development in the same way as other institutions around the world. However, the establishment and development of universities in Palestine meant that Palestine was investing in Palestinians, and, for reasons discussed in this paper, the development represented a clear breakthrough to be celebrated throughout Palestinian society. Most of the previous studies on the Economics of Higher Education (HE have not explicitly dealt with the Economics of Higher Education under occupation, especially in Palestine, neglecting much of the broader context and strategic impact of Palestinian Higher Education. This research investigates in depth Palestinian HE socio-economic outcomes for Palestinians, bringing to the light the meaning of HE under occupation that goes beyond mere economic impact to include its impact on Palestinians' human capital, dignity, and national identity reflecting the unique case of Palestine. This research reveals that from very early on it was clear that Palestinian Higher Education could not give the economy a boost, but that universities did give people a pride in Palestine, which, given the conditions of a brutal military occupation that increasingly separated one Palestinian from the next, amounted to quite a significant achievement. It demonstrated the central role Palestinian HE plays in the life of Palestinians as it is goes beyond means of economic growth to means of survival, building human capital, and maintaining people's dignity and national identity.

    This article examines some techno-political aspects of the early years of electrification in British-ruled 1920s Palestine. It emphasizes the importance of local technical, topographical and hydrological forms of knowledge for understanding the dynamics of electrification. Situating the analysis in a general colonial context of electrification, the study shows that British colonial rulers lagged behind both German firms and local entrepreneurs in understanding the specific conditions pertaining to electrification in Palestine. Subsequently, the study shows that the British had limited control of the actual electrification process and its declared/professed developmental purposes, thereby complicating assumptions about electrification as a tool of the Empire/tool of empire. Finding some similarities between the cases of electrifying Palestine and India, the article's findings may shed further light on the importance of micro-politics of knowledge for understanding the trajectory of electrification in the colonies.

    Full Text Available Abstract Background Medical research productivity reflects the level of medical education and practice in a particular country. The objective of this study was to examine the quantity and quality of medical and biomedical research published from Palestine. Findings Comprehensive review of the literature indexed by Scopus was conducted. Data from Jan 01, 2002 till December 31, 2011 was searched for authors affiliated with Palestine or Palestinian authority. Results were refined to limit the search to medical and biomedical subjects. The quality of publication was assessed using Journal Citation Report. The total number of publications was 2207. A total of 770 publications were in the medical and biomedical subject areas. The annual rate of publication was 0.077 articles per gross domestic product/capita. The 770 publications have an h-index of 32. One hundred and thirty eight (18% articles were published in 46 journals that were not indexed in the web of knowledge. Twenty two (22/770; 2.9% articles were published in journals with an IF > 10. Conclusions The quantity and quality of research originating from Palestinian institutions is promising given the scarce resources of Palestine. However, more effort is needed to bridge the gap in medical research productivity and to promote better health in Palestine.

    2017-05-05

    This study investigates emotional display rules within the Palestinian context, focusing on the seven basic emotions in a sample of 150 college students from the Gaza Strip and the West Bank. Overall, participants felt that it was more appropriate to express positive emotions (happiness and surprise) than negative powerful (anger, contempt and disgust) or negative powerless (fear and sadness) emotions. They also perceived it to be more appropriate to express positive and negative powerless emotions to ingroup than outgroup members and to express negative powerful emotions to lower status compared to higher status individuals. Gender differences were also found: men endorsed greater expression of both powerful and, surprisingly, powerless emotions than women, but only when interacting with outgroup members. Results are interpreted in terms of the cultural values of individualism-collectivism and power distance as well as cultural differences in emotional expressiveness between collectivistic societies. This study is one of the first to examine emotional display rules in an Arab population, thus expanding our current knowledge base. © 2017 International Union of Psychological Science.

    Gampe, David; Ludwig, Ralf

    2013-04-01

    According to current climate projections, Mediterranean countries are at high risk for an even pronounced susceptibility to changes in the hydrological budget and extremes. While there is scientific consensus that climate induced changes on the hydrology of Mediterranean regions are presently occurring and are projected to amplify in the future, very little knowledge is available about the quantification of these changes, which is hampered by a lack of suitable and cost effective hydrological monitoring and modeling systems. The European FP7-project CLIMB is aiming to analyze climate induced changes on the hydrology of the Mediterranean Basins by investigating seven test sites located in the countries Italy, France, Turkey, Tunisia, Gaza and Egypt. CLIMB employs a combination of novel geophysical field monitoring concepts, remote sensing techniques and integrated hydrologic modeling to improve process descriptions and understanding and to quantify existing uncertainties in climate change impact analysis. One of those seven sites is the Gaza Strip, located in the Eastern Mediterranean and part of the Palestinian Autonomous Area, covers an area of 365km² with a length of 35km and 6 to 12km in width. Elevation ranges from sea level up to 104m in the East of the test site. Mean annual precipitation varies from 235mm in the South to 420mm in the North of the area. The inter annual variability of rainfall and the rapid population growth in an highly agricultural used area represent the major challenges in this area. The physically based Water Simulation Model WaSiM Vers. 2 (Schulla & Jasper (1999)) is setup to model current and projected future hydrological conditions. The availability of measured meteorological and hydrological data is poor as common to many Mediterranean catchments. The lack of available measured input data hampers the calibration of the model setup and the validation of model outputs. WaSiM was driven with meteorological forcing taken from 4

    Full Text Available This paper aims to examine how literacy rate affects unemployment among different ages in Palestine. Using labour force surveys and annual reports of Palestinian Central Bureau of Statistics (PCBS, 2000-2015, we analyzed 16 years (2000-2015 regarding unemployment percentage and literacy rates among different ages in both genders in Palestine. Linear regression models were used to show how literacy rate affects unemployment among the various ages. The results showed that literacy rate is significantly correlated with the percentage of unemployment among ages of (15 to 24, 25 to 34, and 35 to 44. Gender is significantly correlated with the percentage of unemployment among the ages of (15 to 24, 25 to 34, and 45 to 54. A positive relationship appears between literacy and unemployment. Females have more unemployment than males among ages of (15 to 24 and 25 to 34. On the other side, females have less unemployment than males in the (35 to 44 and 45 to 54 age categories.

  14. [The organization of Jewish dentists in pre-Israel Palestine].

    Science.gov (United States)

    Keren-Kratz, M

    2016-04-01

    The first modern dental institutes were established in Europe and in the USA during the 1840s. At that period there wasn't a single qualified doctor in Palestine, not to mention a professional dentist. A couple of decades later, as the number of Christian pilgrims grew, some modern hospitals were established and a few non-Jewish dentists opened their clinics in Jerusalem, which was then and in the following decades, the region's largest city. In Europe, dentistry became a popular profession among Jews in general and among Jewish women in particular. The first Jewish dentist settled in Jerusalem in the mid-1880s. Other dentists were slow to arrive and their number began to grow only after the turn of the 20th century. Their professional education varied from those who were trained as apprentices by other dentists to those which studied a couple of years in an academic dental school. The devastation caused by WWI prompted American-Zionist organizations to send a special medical unit to Palestine in 1918. Along medical supplies it also brought a small group of doctors and dentists. The two American dentists that decided to remain in Palestine took upon themselves to spread their medical and scientific knowledge. They also organized the dentists, whose number grew considerably during the 1920s, and called the authorities to regulate the dental profession. In 1926 the British authorities issued a decree regulating all medical professions. It demanded that dental practitioners will be licensed after proving their previous studies and professional knowledge. In 1931, local dentists' organizations decided to establish the Palestine Dental Association. Five years later it was accepted as a member by the International Dental Federation (FDI) and was recognized by the local authorities. Since the 1930s, prominent Jewish dentists from abroad were invited to come to Palestine to lecture, and local dentists participated in international conferences. This prompted the first

    The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), the main primary healthcare provider for 4.9 million Palestinian refugees, spent USD18.3 million on essential medicines dispensed free-of-charge through clinics in five areas of operation ('fields'): Gaza, Jordan, Lebanon, Syria, and the West Bank (2010). Faced with budget contraints and an increasing demand for medicines to treat chronic conditions, the objective of our study was to assess UNRWA's medicine procurement prices to see if savings could be possible. In July 2011, data was collected from UNRWA headquarters in Jordan. Price analyses focused on the top 80 medicines by value, accounting for 93% of pharmaceutical expenditure from the General Fund, with comparisons to international, regional and national references. Prices were also compared for the few medicines procured both through UNRWA's central tender (centrally) and by the fields directly (locally). Central procurement prices did not differ markedly from reference prices: median ratios of UNRWA prices to Management Sciences for Health's International Drug Price Indicator Guide, Jordan's Joint Procurement Department, Gulf Cooperation Council, and IDA Foundation bulk packs were 0.99, 1.00, 0.98 and 1.12 respectively. Applying the lowest comparator price to five comparatively higher priced medicines would yield savings of USD1.4 million. Local procurements were generally less cost-effective than central tender procurement, with notable differences across fields and medicines. Overall, UNRWA's procurement prices were competitive despite the relatively small quantities procured. Regular monitoring of procurement prices and quantities is needed in order to make informed decisions. Our evaluation also underscores the heavy burden of antidiabetic medicines and antimicrobials on UNRWA procurement expenditure.

    About 16 000 Micro Strip Gas Chambers like this one will be used in the CMS tracking detector. They will measure the tracks of charged particles to a hundredth of a millimetre precision in the region near the collision point where the density of particles is very high. Each chamber is filled with a gas mixture of argon and dimethyl ether. Charged particles passing through ionise the gas, knocking out electrons which are collected on the aluminium strips visible under the microscope. Such detectors are being used in radiography. They give higher resolution imaging and reduce the required dose of radiation.

    1995-04-01

    At the end of the 80's, some of the large European airlines expressed a wish for paint systems with improved strippability on their aircraft, allowing the possibility to strip down to the primer without altering it, using 'mild' chemical strippers based on methylene chloride. These improvements were initially intended to reduce costs and stripping cycle times while facilitating rapid repainting, and this without the need to change the conventionally used industrial facilities. The level of in-service performance of these paint systems was to be the same as the previous ones. Requirements related to hygiene safety and the environment were added to these initial requirements. To meet customers' expectations, Aerospatiale, within the Airbus Industry GIE, formed a work group. This group was given the task of specifying, following up the elaboration and qualifying the paint systems allowing requirements to be met, in relation with the paint suppliers and the airlines. The analysis made in this report showed the interest of transferring as far upstream as possible (to paint conception level) most of the technical constraints related to stripping. Thus, the concept retained for the paint system, allowing selective chemical stripping, is a 3-coat system with characteristics as near as possible to the previously used paints.

    An innovative photosensitive gaseous detector, consisting of a GEM like amplification structure with double layered electrodes (instead of commonly used metallic ones) coated with a CsI reflective photocathode, is described. In one of our latest designs, the inner electrode consists of a metallic grid and the outer one is made of resistive strips; the latter are manufactured by a screen printing technology on the top of the metallic strips grid The inner metallic grid is used for 2D position measurements whereas the resistive layer provides an efficient spark protected operation at high gains - close to the breakdown limit. Detectors with active areas of 10cm x10cm and 10cm x20cm were tested under various conditions including the operation in photosensitive gas mixtures containing ethylferrocene or TMAE vapors. The new technique could have many applications requiring robust and reliable large area detectors for UV visualization, as for example, in Cherenkov imaging devices.

    2015-11-01

    The selection of an ambush-cum-foraging site and proper prey are indispensable for maintaining an adequate energy intake by sit-and-wait predators to optimize survival and future fitness. This is important for snakes, where an ambush site has suitable ambience. We studied the foraging strategy of the Palestine Saw-scaled Viper (Echis coloratus) at an avian migratory stopover site. Following initial observations, we hypothesized that vipers are able to discern the body mass of a perched bird and hunt accordingly. We implemented an experiment where vipers chose between four groups of migratory Blackcaps with different body mass. Prey choice by vipers of both age classes was not random and adults focused on Blackcaps with the lightest body mass. Juveniles displayed a variability of prey choice but selected mainly birds from the lightest categories. We concluded that Saw-scaled Vipers hunt prey based on thermal cues; juveniles practice on different prey groups prior to perfecting their foraging techniques i.e., hunting is a learned process; and that they prefer birds with the lowest body mass. The last because Blackcaps, when on migration, save energy by entering a state of deep torpor in which they sacrifice their vigilance capabilities. Copyright © 2015 Elsevier B.V.

  14. A Cost Analysis of Kidney Replacement Therapy Options in Palestine

    2015-03-01

    Full Text Available This study provides a cost analysis of kidney replacement therapy options in Palestine. It informs evidence-based resource allocation decisions for government-funded kidney disease services where transplant donors are limited, and some of the common modalities, i.e., peritoneal dialysis (PD and home hemodialysis (HD, are not widely available due to shortages of qualified staff, specialists, and centers to follow the patient cases, provide training, make home visits, or provide educational programs for patients. The average cost of kidney transplant was US$16 277 for the first year; the estimated cost of HD per patient averaged US$16 085 per year—nearly as much as a transplant. Consistent with prior literature and experience, while live, related kidney donors are scarce, we found that kidney transplant was more adequate and less expensive than HD. These results have direct resource allocation implications for government-funded kidney disease services under Palestinian Ministry of Health. Our findings strongly suggest that investing in sufficient qualified staff, equipment, and clinical infrastructure to replace HD services with transplantation whenever medically indicated and suitable kidney donors are available, as well as deploying PD programs and Home HD programs, will result in major overall cost savings. Our results provide a better understanding of the costs of kidney disease and will help to inform Ministry of Health and related policy makers as they develop short- and long-term strategies for the population, in terms of both cost savings and enhanced quality of life.

    2003-12-01

    Full Text Available The essence of the British military and security formula in Palestine was the smooth establishment of the Jewish national home with minimum costs of lives and money. However, this British pro-Zionist policy created a continuous security problem, and opened the door to all possibilities of Palestinian revolts and uprisings of both national and religious nature. The British were very active in disarming the Arabs and adopted stringent measures to crush their uprisings and revolts. But, they turned a blind eye to the Jewish arms smuggling and Jewish military organizations, especially, the Hagana, which later became the backbone of the Israeli Army. During Palestinian uprisings of 1920, 1921 and 1929 against the Zionists, most of the Palestinian casualties were inflicted by the British forces despite the fact that the Palestinians avoided attacking the British. The British-Zionist cooperation reached its peak during the Palestinian revolt of 1936-1939, and took different forms, including allowing the Jews to establish a military force of twenty two thousand men under the pretext of protecting the Jewish community.

    2007-01-01

    Environmental Management of stone cutting industry in Hebron, Palestine, is required to reduce the industry's adverse impacts on the downstream agricultural land and on the drinking water aquifers. This situation required the implementation of an industrial waste water management strategic approach and technology within the environmental need and available technical and financial resources. Ten pilot projects at different locations were built at Hebron to reduce or eliminate the incompatible discharge of the liquid and solid waste to the environment and improve the stone cutting industry's effluent quality. A review of existing practices and jar test experiments were used to optimize the water recycling and treatment facilities. The factors reviewed included influent pumping rates and cycles, selection of the optimal coagulant type and addition methods, control of sludge recycling process, control over flow rates, control locations of influent and effluent and sludge depth. Based on the optimized doses and Turbidity results, it was determined that the use of Fokland polymer with an optimal dose of 1.5 mg/L could achieve the target turbidity levels. The completion of pilot projects resulted in the elimination of 18% of the total stone cutting waste discharges in Hebron. The results included an improvement in the recycled effluent quality by 44.99%. This in turn reduced the long term operating costs for each participating firm. A full-scale project that will include all the stone cutting firms in Hebron industrial area is required. (author)

    Full Text Available Abstract: An Analysis of the Islamic and Conventional Banking Profitability in Palestine. The research paper examines the performance of profitability of Islamic banks against conventional banks for the period of 2005 to 2010. Two alternative measurements of banking profitability such as Return on Equity (ROE and Return on Assets (ROA are used to examine whether there is any differences of profit rate between Islamic, local and foreign conventional banks. The study concludes that Islamic banks generally provide the similar profit rate compared to local banks, however Islamic banks provide lower profit rate compared to foreign banks. Finally the findings also suggest that there is no statistical significant difference in mean return between the Islamic banks, local and foreign banks in Palestine. The study recommends the critical needs for Islamic regulation in order to improve the role of Islamic banking industry in Palestine.

    2006-05-10

    Spray forming is a competitive low-cost alternative to ingot metallurgy for manufacturing ferrous and non-ferrous alloy shapes. It produces materials with a reduced number of processing steps, while maintaining materials properties, with the possibility of near-net-shape manufacturing. However, there are several hurdles to large-scale commercial adoption of spray forming: 1) ensuring strip is consistently flat, 2) eliminating porosity, particularly at the deposit/substrate interface, and 3) improving material yield. Through this program, a new strip/sheet casting process, termed spray rolling, has been developed, which is an innovative manufacturing technique to produce aluminum net-shape products. Spray rolling combines the benefits of twin-roll casting and conventional spray forming, showing a promising potential to overcome the above hurdles associated with spray forming. Spray rolling requires less energy and generates less scrap than conventional processes and, consequently, enables the development of materials with lower environmental impacts in both processing and final products. Spray Rolling was developed as a collaborative project between the University of California-Davis, the Colorado School of Mines, the Idaho National Engineering and Environmental Laboratory, and an industry team. The following objectives of this project were achieved: (1) Demonstration of the feasibility of the spray rolling process at the bench-scale level and evaluation of the materials properties of spray rolled aluminum strip alloys; and (2) Demonstration of 2X scalability of the process and documentation of technical hurdles to further scale up and initiate technology transfer to industry for eventual commercialization of the process.

  1. Electronic rumble strip

    Stauffer, Donald R.; Lenz, James

    1997-02-01

    Single vehicle run-off-road accidents are responsible for significant numbers of injuries and fatalities, and significant property damage. This fact spurs interest in warning systems to alert drivers that vehicles are drifting towards the edge of the road, and that a run-off road accident is imminent. An early attempt at such a warning system is the use of machined grooves on the shoulder to create a rumble strip. Such a system only provides warning, however, as the vehicle actually leaves the traffic lane. More desirable is a system that warns in anticipation of such departure. Honeywell has under development a magnetic lateral guidance system that couples a sensitive magnetoresistive transducer with a magnetic traffic marking tape being developed by 3M. While this development was initially undertaken for use in automated highways, or for special tasks such as guiding snowplow owners, the system can provide an effective, all-weather warning system to provide alert of impending departure from the roadway. This electronic rumble strip is actually a simpler system than the baseline guidance system, and can monitor both distance from the traffic lane edge and the speed of approach to the edge with a low cost sensor.

    This work presents the results of exposure levels to radio frequency (RF) emission from different sources in the environment of the West Bank-Palestine. These RF emitters include FM and TV broadcasting stations and mobile phone base stations. Power densities were measured at 65 locations distributed over the West Bank area. These locations include mainly centres of the major cities. Also a 24 h activity level was investigated for a mobile phone base station to determine the maximum activity level for this kind of RF emitters. All measurements were conducted at a height of 1.7 m above ground level using hand held Narda SRM 3000 spectrum analyzer with isotropic antenna capable of collecting RF signals in the frequency band from 75 MHz to 3 GHz. The average value of power density resulted from FM radio broadcasting in all investigated locations was 0.148 μW cm -2 , from TV broadcasting was 0.007 μW cm -2 and from mobile phone base station was 0.089 μW cm -2 . The maximum total exposure evaluated at any location was 3.86 μW cm -2 . The corresponding exposure quotient calculated for this site was 0.02. This value is well below unity indicating compliance with the International Commission on non-ionising Radiation protection guidelines. Contributions from all relevant RF sources to the total exposure were evaluated and found to be ∼62 % from FM radio, 3 % for TV broadcasting and 35 % from mobile phone base stations. The average total exposure from all investigated RF sources was 0.37 μW cm -2 . (authors)

  3. Apartheid in the Holy Land: Theological reflections on the Israel and/or Palestine situation from a South African perspective

    2016-11-01

    Full Text Available I first attempt to draw a comparison between the Israel-Palestine conflict and the South African experience of apartheid. Drawing on other established sources and personal experience, I conclude that, while there may be some differences between the two contexts, in essence, the similar experiences of colonialisation and racialisation makes the apartheid comparison compellingly relevant. I then proceed to theologically explore the themes of justice and reconciliation and what it may mean in the context of Israel-Palestine whilst extracting from the South African experience. The article also offers some reflections on the role of the Church in addressing the Israel-Palestine conflict.

    2015-12-01

    Full Text Available Films from or about Palestine are frequently programmed at international film festivals. They are sometimes released in cinemas and quite often presented in special screenings at various institutions all over the Western World. Due to the scarcity of screens and the boycott of Israel, they are seen to a lesser extend in Arab countries. Compared to screenings of other Arab films or the presentation of movies from other former colonies and mandatory territories, Western audiences often react highly emotional to the images from Palestine. In debates questions for a better understanding of the films’ subject or context are barely ever asked. Rather the foreign spectators seem to have a sense of belonging and to claim the right for co-determination. Where do these emotional ties originate from? In recent years a large number of films shot in Palestine during the late Ottoman period and the British mandate were made accesssible online, mainly by the Steven Spielberg Film Archive in Jerusalem and the British War Museum in London. Libraries like the Library of Congress in Washington digitized parts of their photographic collections. Based on them as well as on the films I work with as distributor and programmer for Arab film series, in this article I look at images on and from Palestine and ask for what purpose, in which context and by whom they were made and distributed.

Howell, Deena Khalil and Salman Elbedour ( Psychological Trauma: Theory, Research, Practice, and Policy , Advanced Online Publication, May 30, 2016, np). There were grammatical errors to the Method section of the abstract and the Method subsection Participants. Corrected versions are provided. (The following abstract of the original article appeared in record 2016-26488-001.) Objective: The pathogenic impact of ongoing political conflict on children and adolescents has been well-documented in the literature. The present study, by contrast, examined the factors that support adolescent health and utilized a salutogenic model to examine prevalence of depression and anxiety and predictors of resilience in a group of adolescents attending secondary school in Gaza. There were 335 Palestinian adolescents (n = 335) enrolled in 11th and 12th grades in secondary schools in Gaza refugee camps completed the Beck Depression Inventory, the Beck Anxiety Inventory, and self-report measures assessing coping skills, self-regulation, optimism, parenting style, family sense of coherence, national identity, ethnic identity, and other demographic variables. Participants with stronger national identity, stronger family sense of coherence, greater self-regulation, and more optimism reported less depressive and anxious symptoms. In a logistic regression analysis, significant predictors of resilience (minimal to no anxiety and depression, n = 135) were age, optimism, family sense of coherence, ethnic identity, self-regulation, and coping skills. These findings indicate that older age, optimism, perception of family seeing the world as comprehensible, manageable, and meaningful, stronger Arab ethnic identity, greater self-regulation and stronger coping skills promote adolescent adaptation and health.

    Gastroenteritis is considered one of the leading causes of morbidity and mortality in children especially in developing countries. It is a major childhood problem in Gaza and one of the most common etiologic agents of iron deficiency anemia (IDA). This study was conducted to investigate possible changes in blood parameters that are associated with gastroenteritis infection among kindergarten children in Gaza. A cross-sectional case-control study was performed including kindergarten children suffering from gastroenteritis and matched healthy control group. Types of etiological agents were identified using standard microbiological and serological procedures. Blood samples were collected for estimation of complete blood count and for determination of serum iron, total iron binding capacity (TIBC), and transferrin saturation. Independent sample t-test was used for comparisons and performed using SPSS software version 17(Chicago Illinois USA). The prevalence of enteric pathogens among cases (88.5% [85/96]) was significantly higher than in asymptomatic controls (11.1% [6/54]). The most common enteric pathogens isolated were Entamoeba histolytica (28% [42/91]) and Giardia lamblia (26.7% [40/91]). Blood tests revealed that 21.8% (21/96) of cases and 14.8% (8/54) of controls had IDA, which were not significantly different. Meanwhile, a significant difference was found between the TIBC and hemoglobin in cases compared to controls. This study indicates that gastroenteritis infection could be considered as a common health problem in kindergarten children in Gaza, and it is possibly associated with changes in hemoglobin concentration and TIBC.

    Resilience and distress in Israeli society were assessed at three points in time: before and after the Israeli disengagement from Gaza, and after the second Lebanese war. A random sample of 366 Israelis was assessed for nation-related anxiety and hostility, personal resources and post-traumatic symptoms. The lowest levels of anxiety were observed at the second time point, after the disengagement. Respondents with high-resilience profiles showed lower levels of post-traumatic symptoms and higher levels of personal resources. The findings underscore Israelis' resilience and the importance of personal resources in ongoing nationally stressful situations.

  17. Range gated strip proximity sensor

    McEwan, T.E.

    1996-12-03

    A range gated strip proximity sensor uses one set of sensor electronics and a distributed antenna or strip which extends along the perimeter to be sensed. A micro-power RF transmitter is coupled to the first end of the strip and transmits a sequence of RF pulses on the strip to produce a sensor field along the strip. A receiver is coupled to the second end of the strip, and generates a field reference signal in response to the sequence of pulse on the line combined with received electromagnetic energy from reflections in the field. The sensor signals comprise pulses of radio frequency signals having a duration of less than 10 nanoseconds, and a pulse repetition rate on the order of 1 to 10 MegaHertz or less. The duration of the radio frequency pulses is adjusted to control the range of the sensor. An RF detector feeds a filter capacitor in response to received pulses on the strip line to produce a field reference signal representing the average amplitude of the received pulses. When a received pulse is mixed with a received echo, the mixing causes a fluctuation in the amplitude of the field reference signal, providing a range-limited Doppler type signature of a field disturbance. 6 figs.

    It is foreseen to increase the luminosity of the LHC at CERN around 2020 by about an order of magnitude (SLHC). The ATLAS experiment will require a new particle tracking system for SLHC operation in order to cope with the increase in background events by about one order of magnitude at the higher luminosity. , an all silicon detector with enhanced radiation hardness is being designed. A massive R&D programme, involving many particles physics groups and several leadings manufacturers of silicon detectors for particle physics, is underway to develop silicon sensors with sufficient radiation hardness. In this framework new sensor materials like p-type silicon and the 3D technology are investigated. In parallel, the SCT commissioning experience has taught us to look into alternative module concepts, in which higher levels of integration are combined with the modularity of the SCT approach. We will report on the status of the R&D projects on radiation hard silicon strip detectors for particle physics, link...

    A phased upgrade of the Large Hadron Collider (LHC) at CERN is planned. The last upgrade phase (HL-LHC) is currently foreseen in 2022-2023. It aims to increase the integrated luminosity to about ten times the original LHC design luminosity. To cope with the harsh conditions in terms of particle rates and radiation dose expected during HL-LHC operation, the ATLAS collaboration is developing technologies for a complete tracker replacement. This new detector will need to provide extreme radiation hardness and a high granularity, within the tight constraints imposed by the existing detectors and their services. An all-silicon high-granularity tracking detector is proposed. An international R&D collaboration is working on the strip layers for this new tracker. A number of large area prototype planar detectors produced on p-type wafers have been designed and fabricated for use at HL-LHC. These prototype detectors and miniature test detectors have been irradiated to a set of fluences matched to HL-LHC expectatio...

    Moreas, G.; Hardy, Y.

    1999-01-01

    With the aim of enhancing coating quality control during galvannealing process, an online microscopic image acquisition sensor has been developed at CRM. In galvannealing process, the ζ phase surface density is a coating quality characteristic, and the on-line microscope, equipped with optics placed at 20 mm from the surface, grabs 250 μm x 190 μm images on which ζ crystals (approximate dimensions: 1 μm x 10 μm) can be clearly identified. On-line, the sensor is mounted in front of a roll where the strip has a stable position. The coating surface to sensor optics distance is continuously measured by an accurate triangulation sensor (1 μm repeatability) and is adjusted in such a way that, due to roll eccentricity, the image is focused at least twice per revolution. When focused, image of moving product is frozen by a short (10 ns) laser light pulse and is grabbed. The obtained image is then processed to extract ζ phase percentage and allows adjustment of process parameters to reach the desired coating characteristics. (author)

    Psoriasis is a frequent skin inflammatory disorder that inflicts millions of patients around the globe. To meet their healthcare needs, patients with psoriasis often seek treatment outside the allopathic paradigm. Use of medicinal plants has emerged as one of the most common and preferred modalities of complementary and alternative medicine (CAM). The aim of this study was to investigate the use of medicinal plants by patients with psoriasis in the West Bank of Palestine. The current study was a questionnaire based cross-sectional descriptive study on the use of medicinal plants by psoriasis patients in the West Bank of Palestine. A sample of 149 patients with psoriasis who were visiting outpatient clinics responded to the questionnaire in face to face interviews. Medicinal plants were used by 81 (54.4%) patients with psoriasis. Patients used 33 medicinal plants belonging to 26 families. Plants belonging to Lamiaceae and Leguminosae were the most commonly used by the study patients. Aloe vera, Trigonella arabica, Catharanthus roseus and Anthemis cotula were the most frequently used medicinal plants to treat psoriasis. Leaves and fruits were the most commonly used parts by the study patients. Paste was the most commonly used form of preparation. The use of medicinal plants was significantly associated with age and monthly household income of the patients. Enhancement of immunity, improving conventional therapy and reduction of side effects were the most commonly self-reported reasons for using medicinal plants. Patients with psoriasis in Palestine seem to use medicinal plants as a CAM modality to manage their psoriasis. Many medicinal plants were commonly used by patients with psoriasis. More randomized clinical trials are needed to demonstrate safety and efficacy for the majority of these medicinal plants reported to be used by patients with psoriasis in Palestine.

    During the summer of 2014, Israel initiated a major air and land offensive against the Gaza strip (Operation ‘Protective Edge’). Palestine responded by engaging in a set of what can be termed ‘coercive policies’, using the threat of activating the jurisdiction of the International Criminal Court...... (ICC) as leverage. This was the first time in history that an international actor used a possible recourse to the Court in such an explicitly coercive manner. Hence, this case enables us to conduct some preliminary analyses of this strategy’s effectiveness. Specifically, Palestine tried first to stop...... the Israeli offensive itself and later, after combat operations had ended, to compel the United Nations (UN) Security Council to demand an Israeli withdrawal to the 1967-borders. Palestine’s policies, however, did not succeed. Its threats did not secure an Israeli withdrawal from Gaza, nor did they compel...

  8. A molecular epidemiology survey of respiratory adenoviruses circulating in children residing in Southern Palestine.

    Directory of Open Access Journals (Sweden)

    Lina Qurei

    Full Text Available A molecular epidemiology survey was performed in order to establish and document the respiratory adenovirus pathogen profiles among children in Southern Palestine. Three hundred and thirty-eight hospitalized pediatric cases with adenovirus-associated respiratory tract infections were analyzed. Forty four cases out of the 338 were evaluated in more detail for the adenoviruses types present. All of the children resided in Southern Palestine, that is, in city, village and refugee camp environments within the districts of Hebron and Bethlehem. Human adenoviruses circulated throughout 2005-2010, with major outbreaks occurring in the spring months. A larger percent of the children diagnosed with adenoviral infections were male infants. DNA sequence analysis of the hexon genes from 44 samples revealed that several distinct adenovirus types circulated in the region; these were HAdV-C1, HAdV-C2, HAdV-B3 and HAdV-C5. However, not all of these types were detected within each year. This is the first study ever conducted in Palestine of the genetic epidemiology of respiratory adenovirus infections.

    2016-03-01

    Full Text Available During the Gaza-Israel conflict of July-August 2014, a large volume of creative, multimodal digital content aimed at influencing public opinion was disseminated on social media by belligerents and their supporters. This paper highlights two related features of this ‘viral agitprop’: the use of a diverse range of novel, hypermediated forms to represent a limited set of messages, and thematisation of the act of mediation itself. I argue that these practices are a response to the challenges of communicating with multiple publics within data streams that are crowded, competitive and fast-moving. I suggest this content represents a distinctive new Internet genre which problematises accounts of the relationship between war and media by Friedrich Kittler and Jean Baudrillard.

  10. Profiles of refugee and non-refugee Palestinians from the West Bank and Gaza.

    Science.gov (United States)

    Al-qudsi, S S

    2000-01-01

    Relying on demographic and labor surveys which the Palestinian Central Bureau of Statistics collected in 1995, this article investigates the profile of West Bank and Gaza refugees. Refugees are better educated and have higher fertility than non-refugee Palestinians, but the difference is small. However, they have a significantly lower participation rate, a higher unemployment rate and a higher incidence of arrests and work stoppage than the corresponding rates among non-refugee Palestinians. A smaller proportion of Palestinians commute to work into the Israeli labor market and refugees earn lower wages than nonrefugees. Returns to investment in education are small for both groups. High fertility among refugees imposes a future challenge for policy makers in terms of resources required for the provision of appropriate education and health facilities. Employing future labor market entrants is another serious policy challenge.

    2018-03-01

    Full Text Available This study sees the city not only as the primary venue of the capitalism, but as a stage of future wars, as it is observed that the city has been taken and thought as a battlespace in contemporary wars. We are considering that the city has been used by insurgent groups such as terrorists, insurgents and drug traffickers, who hide and use the physical infrastructure of the city in fighting regular armies as a way to reduce military power disparities. Because of this, his life in the city has been affected by conflicts in urban terrain, that aim to not only destroy the enemy, but to destroy its survival space, denying the city. This destruction of the urban space as part of a war strategy, is first analyzed in Gaza, and then to question the extent to which this occurs in the city of Rio de Janeiro.

    An analysis of the strip waveguide is presented with special emphasis on reflection and transmission of a wave obliquely incident on the side of a strip. Mode conversion and the contribution of radiation modes are taken into account in the formulation. The numerical results of the mode conversion and attenuation constant of the fundamental leaky mode are presented and compared with the results of other authors. The numerical accuracy of our analysis is also checked by two different procedures. It is found that the radiation modes have considerable effects on the waveguide characteristics.

    The purpose of this study was to evaluate the results of gluteal suspension with polypropylene strips. Ninety healthy female patients between the ages of 20 and 50 years (mean, 26 years), who wished to remodel their buttocks from December 2004 to February 2013 were studied retrospectively. All 90 patients were treated with 2 strips of polypropylene on each buttock using the following procedures: 27 (30 %) patients were suspended with polypropylene strips; 63 (70 %) patients were treated with tumescent liposuction in the sacral "V", lower back, supragluteal regions, and flanks to improve buttocks contour (aspirated volume of fat from 350 to 800 cc); 16 (18 %) patients underwent fat grafting in the subcutaneous and intramuscular layers (up to 300 cc in each buttock to increase volume); 5 (6 %) patients received implants to increase volume; and 4 (4.4 %) patients underwent removal and relocation of intramuscular gluteal implants to improve esthetics. Over an 8-year period, 90 female patients underwent gluteal suspension surgeries. Good esthetic results without complications were obtained in 75 of 90 (84 %) cases. Complications occurred in 15 of 90 (16.6 %) patients, including strip removal due to postoperative pain in 1 (1.1 %) patient, and seroma in both subgluteal sulci in 3 (3.3 %) patients. The results of this study performed in 90 patients over 8 years showed that the suspension with polypropylene strips performed as a single procedure or in combination with other cosmetic methods helps to enhance and lift ptosed gluteal and paragluteal areas.

    2006-06-01

    On 21st November 1916, the Royal Navy Hospital ship 'Britannic' (the sister ship of the 'Titanic') was torpedoed near the island of Kea in the Aegean Sea. Captain Dr. John Cropper, aged 52, was one of 30 people who drowned of the 1100 on board. Dr. Cropper was born in 1864, at Guisborough, England. He obtained his medical degree from Cambridge University in 1891. After his marriage to Anne Ellen Walker in 1895, the Church Missionary Society sent him on a medical mission to Palestine. Dr. Cropper stayed in Palestine for about 10 years working in Acre, Nablus, Ramallah and Jerusalem. He published his experiences in 35 articles and letters in English medical periodicals, more than anyone else did in Palestine at that time. In those publications, he described various operations that he carried out and observations on infectious diseases, most of which were the first descriptions from that remote and unhealthy country. His prominent research was in the field of malaria - the most common and important disease in Palestine during that period. It was less than two years after Grassi's discovery of the role of Anopheles mosquitoes as the vector of human malaria that Dr. Cropper carried out surveys of larval and adult mosquitoes in correlation with malarial distribution in Palestine. Dr. Cropper was the first who routinely examined slides microscopically in Palestine and correctly diagnosed the type of malaria. Dr. Cropper was also the first in Palestine to suggest antimalarial measures aimed directly at the mosquito vector and paid attention to ecological aspects such as breeding places and the daily behavior of adult mosquitoes. Dr. Cropper noted the common antimalarial measurements of that time, such as covering of wells, planting of Eucalyptus trees to drain swamps and the routine use of quinine as a preventive medicine, but he wrote that those measures were not effective under the local conditions. He suggested that the only effective measures must be aimed against the

    Recent ethnopharmacological surveys showed that herbal remedies are the most preferred modality of complementary and alternative medicine (CAM). In Palestine as in many other countries, herbal remedies are widely used in the treatment of many diseases. The aim of this study was to investigate the use of herbal remedies by women living with breast cancer in the West Bank of Palestine. This study was a questionnaire based cross-sectional descriptive study on the use of herbal remedies by breast cancer patients in the West Bank. A questionnaire was distributed to 115 patients at outpatient cancer clinics in face to face interviews. The study had a response rate of 89.6%. Of all respondents, 68% were herbal remedies users. Women with breast cancer used 46 plant species belonging to 32 families. Of these, Brassicaceae and Lamiaceae were the most prevalent. Ephedra alata was the most commonly used plant species in the treatment of breast cancer. Leaves and seeds were the most commonly used parts and decoction was the most commonly used method of preparation. Herbal remedies users were more likely to use herbal remedies instead of chemotherapy. The most commonly stated reason for using herbal remedies was the belief in boosting the patient's immune system to fight cancer. The use of herbal remedies is prevalent in breast cancer patients in Palestine. The use of herbal remedies was associated with educational level, time since diagnosis, type of surgery use, and use of endocrine therapy. It was apparent that the majority of users were satisfied with herbal remedies use. Clinical trials and pharmacological tests are required to be established for the presence of side effects, toxicity and efficacy for these herbal remedies. Copyright © 2015 Elsevier Ireland Ltd.

    Mental health system reform is urgently needed in Gaza to respond to increasing mental health consequences of conflict. Evidence from mental health systems research is needed to inform decision-making. We aimed to provide new knowledge on current mental health policy and legislation, and services and resource use, in Gaza to identify quality gaps and areas for urgent intervention. As part of a mixed methods study, we used the World Health Organization's Assessment Instrument for Mental Health Systems Version 2·2 to collect data on mental health services and resources. Data collection was carried out in 2011, based on the year 2010. Gaza's mental health policy suggests some positive steps toward reform such as supporting deinstitutionalisation of mental health services. The decrease in the number of beds in the psychiatric hospital and the progressive transition of mental healthcare toward more community based care are indicative of deinstitutionalisation. However, mental health legislation in support of deinstitutionalisation in Gaza is lacking. The integration of mental health into primary healthcare and general hospitals has not been fully achieved. Mental health in Gaza is underfunded, human rights protection of service users is absent, and human resources, service user advocacy, and mental health training are limited. Priority needs to be given to human rights protection, mental health training, and investment in human and organisational resources. Legislation is needed to support policy and plan development. The ongoing political conflict and expected increase in need for mental health services demonstrates an urgent response is necessary.

The migration movement to the Palestinian lands for Zionist purposes covers a period for the Jewish people full of patience, seriousness and sacrifices. Especially the rich Jews living in Europe and America supplied the money flow through the companies they set up and the Jews who were the idea-father of the Zionism made great efforts to get the Jewish people all over the world to migrate to the holy lands.

    2018-02-01

    Geochemical studies of planetary accretion and evolution have invoked various degrees of collisional erosion to explain differences in bulk composition between planets and chondrites. Here we undertake a full, dynamical evaluation of 'crustal stripping' during accretion and its key geochemical consequences. Crusts are expected to contain a significant fraction of planetary budgets of incompatible elements, which include the major heat producing nuclides. We present smoothed particle hydrodynamics simulations of collisions between differentiated rocky planetesimals and planetary embryos. We find that the crust is preferentially lost relative to the mantle during impacts, and we have developed a scaling law based on these simulations that approximates the mass of crust that remains in the largest remnant. Using this scaling law and a recent set of N-body simulations of terrestrial planet formation, we have estimated the maximum effect of crustal stripping on incompatible element abundances during the accretion of planetary embryos. We find that on average approximately one third of the initial crust is stripped from embryos as they accrete, which leads to a reduction of ∼20% in the budgets of the heat producing elements if the stripped crust does not reaccrete. Erosion of crusts can lead to non-chondritic ratios of incompatible elements, but the magnitude of this effect depends sensitively on the details of the crust-forming melting process on the planetesimals. The Lu/Hf system is fractionated for a wide range of crustal formation scenarios. Using eucrites (the products of planetesimal silicate melting, thought to represent the crust of Vesta) as a guide to the Lu/Hf of planetesimal crust partially lost during accretion, we predict the Earth could evolve to a superchondritic 176Hf/177Hf (3-5 parts per ten thousand) at present day. Such values are in keeping with compositional estimates of the bulk Earth. Stripping of planetary crusts during accretion can lead to

    Full Text Available Abstract Background Canine visceral leishmaniasis (CVL is caused by Leishmania infantum in all Mediterranean countries. The Leishmania parasite is transmitted by the bite of a corresponding sand fly vector and primarily maintained in nature by wild and domestic reservoirs, including dogs, foxes and jackals. Infected dogs are the primary reservoir host in endemic regions and are the most significant risk disposing humans to infection. The present study aimed at assessing the prevalence of infection with Leishmania and identification of Leishmania infantum in domestic dogs in the West Bank, Palestine. Methods The infection rate among domestic dogs collected from seven districts in the Palestinian West Bank was investigated by examination of parasites in culture from the buffy coat using serological and molecular methods; based on ELISA, internal transcribed spacer 1 (ITS1 and cysteine protease (CPB PCR. Results Out of 215 dogs examined for Leishmania, 36 (16.7% were positive in at least one method. Twenty three animals (11.5% were positive for Leishmania DNA, whereas, ELISA and culture revealed 16 (7.5%, and 4 (1.5% respectively. CPB-PCR on one of three culture-positive isolates revealed Leishmania infantum as the causative agent for Leishmania infection in dogs. Conclusions Our study showed that canine leishmania infection is prevalent with varying degrees in all the seven studied districts in Palestine despite the absence of human VL cases in 4 of these districts. The causative agent was confirmed to be Leishmania infantum.

    Until 1929, midwifery in Palestine was relatively open to anyone and only partially regulated by the 1918 Public Health Ordinance, legislated shortly after the beginning of British rule. This article describes the factors that guided the shaping of midwifery and suggests possible sources of inspiration for the British legislator in crafting the Midwives Ordinance in 1929, including American, local (Jews and Arabs), and British ones. The Midwives Ordinance reflects the adjustment of midwifery to changes in the society that evolved under the British Mandate. The ordinance shows how the modern midwife's role contracted relative to the traditional one, in the context of social processes in other countries, east and west. This historical research project is based on interviews, archive documents and research literature. It analyzes the British interests in regulating midwifery, including the rationale of preserving public health and reducing infant mortality, against a background of political power struggles as well as cultural, social and professional diversity in Palestine (the tensions between the powers of doctors, nurses, and pharmacists).

    To compare the nature and determinants of child discipline in Qatar and Palestine among young adults through retrospective survey to develop legislation, policies and interventions for effective prevention of child maltreatment, and educational materials to promote positive discipline among parents and caregivers. Cross-sectional random household surveys were conducted in each country (Qataris N=697, Palestinians N=2064) using ISPCAN Child Abuse Screening Tool-Retrospective (ICAST-R) for young adults (18-24 years), to investigate child discipline methods into the maltreatment range. Qatari young adults were more educated (pdiscipline they received in childhood was not reasonable and not justified compared to Palestinian participants. The more advantaged Qatari population was less likely to experience disciplinary methods that experts developing the ICAST-R defined as abuse compared to Palestinians where the higher incidence of child abuse could be attributed to lower economic advantage, lower level of education and greater exposure to violence. Suggestions are made for future studies in Qatar and Palestine to develop survey methodology with a more culturally appropriate level of intrusion, such as indirect yet meaningful child maltreatment questions.

  5. Investigating the Relationship Between Drone Warfare and Civilian Casualties in Gaza

    Directory of Open Access Journals (Sweden)

    Dr. Ann Rogers

    2014-12-01

    Full Text Available Unmanned aerial vehicles (UAVs, better known as drones, are increasingly touted as ‘humanitarian’ weapons that contribute positively to fighting just wars and saving innocent lives. At the same time, civilian casualties have become the most visible and criticized aspect of drone warfare. It is argued here that drones contribute to civilian casualties not in spite of, but because of, their unique attributes. They greatly extend war across time and space, pulling more potential threats and targets into play over long periods, and because they are low-risk and highly accurate, they are more likely to be used. The assumption that drones save lives obscures a new turn in strategic thinking that sees states such as Israel and the US rely on large numbers of small, highly discriminating attacks applied over time to achieve their objectives. This examination of Israel’s 2014 war in Gaza argues that civilian casualties are not an unexpected or unintended consequence of drone warfare, but an entirely predictable outcome.

    While the Large Hadron Collider (LHC) at CERN has started operation in autumn 2008, plans for a luminosity upgrade to the Super-LHC (sLHC) have already been developed for several years. This projected luminosity increase by an order of magnitude gives rise to a challenging radiation environment for tracking detectors at the LHC experiments. Significant improvements in radiation hardness are required with respect to the LHC. Using a strawman layout for the new tracker of the ATLAS experiment as an example, silicon strip detectors (SSDs) with short strips of 2-3 cm length are foreseen to cover the region from 28 to 60 cm distance to the beam. These SSD will be exposed to radiation levels up to 10{sup 15}N{sub eq}/cm{sup 2}, which makes radiation resistance a major concern for the upgraded ATLAS tracker. Several approaches to increasing the radiation hardness of silicon detectors exist. In this article, it is proposed to combine the radiation hard 3D-design originally conceived for pixel-style applications with the benefits of the established planar technology for strip detectors by using SSDs that have regularly spaced doped columns extending into the silicon bulk under the detector strips. The first 3D SSDs to become available for testing were made in the Single Type Column (STC) design, a technological simplification of the original 3D design. With such 3D SSDs, a small number of prototype sLHC detector modules with LHC-speed front-end electronics as used in the semiconductor tracking systems of present LHC experiments were built. Modules were tested before and after irradiation to fluences of 10{sup 15}N{sub eq}/cm{sup 2}. The tests were performed with three systems: a highly focused IR-laser with 5{mu}m spot size to make position-resolved scans of the charge collection efficiency, an Sr{sup 90}{beta}-source set-up to measure the signal levels for a minimum ionizing particle (MIP), and a beam test with 180 GeV pions at CERN.

    1982-01-01

    A new approach is presented to diffraction problems involving plane strip barriers or slit apertures. These are problems that display the effects of multiple interacting edges. The approach taken here provides exact, compact solutions. The theory is introduced through a series of examples that are, in fact, the 'standard' problems of the subject, diffraction of a plane oblique wave by a slit, for example. In each case, the solutions are found to depend explicitly on a single 'special' function and its Fourier transform. These fundamental functions are described, with the emphasis placed on practical computational methods. The example problems are all couched in the language of acoustics.

    Full Text Available The German press has often been accused of fanning, through one-sided reportage (bias on the Israeli-Palestinian conflict, not only anti-Israeli, but also anti-Semitic attitudes in their readers. A content analytic study by Maurer and Kempf (2011 of a representative sample of the reportage on the second Intifada and the Gaza war does not support these claims. The study concentrated above all on escalation vs. de-escalation-oriented representations of the conflict parties. Using the same text material (N = 396 newspaper articles, the present study has the aim of determining the representation (framing of Israeli and Palestinian victims, as well as the representation of responsibility for this victimization in German quality newspapers. By means of Latent Class Analysis, consistent patterns of style characteristics are identified that emphasize or suppress the aspects of victimization and responsibility. These media frames are then studied in regard to their partisanship (bias and tendency over time (second Intifada vs. Gaza war. It was found that from the second Intifada to the Gaza war the media frames increasingly show a pro-Palestinian bias, while the pro-Israeli bias in the reportage becomes weaker. In part, this is counterbalanced in that frames that try for balance with a pro-Israeli tendency emphasize Israeli civilian victims. Thereby all the newspapers studied display the here identified forms of bias to the same degree, so that it is not the press „in itself“ that can be judged to be biased, but rather the individual articles in all the newspapers take clear positions.

    Full Text Available Die deutsche Medienberichterstattung über den Nahost-Konflikt wurde verschiedentlich dahingehend kritisiert, einen anti-israelische Bias zu haben, der die alten, gebräuchlichen Vorurteile und Stereotype gegenüber Juden stärke und die Anschuldigung unterstütze, die Juden würden die Tragik des Holocaust missbrauchen um die israelische Palästina-Politik zu rechtfertigen: Insbesondere während des Gaza-Krieges sei Israel als Aggressor dargestellt, der palästinensische Terrorismus dagegen heruntergespielt worden. Bisher gibt es kaum systematische Forschung zu dieser Frage. Die vorliegende Studie soll diese Lücke zu füllen helfen, indem sie eine vergleichende Inhaltsanalyse der Berichterstattung über die 2.

Die Ergebnisse der Studie zeigen, dass die Darstellung beider Konflikte weit differenzierter war als von ihren Kritikern angenommen. Auch während des Gaza-Krieges hat die deutsche Qualitätspresse ihr Bestes getan, sich nicht auf die Seite der Palästinenser zu schlagen. Falls sie tatsächlich zur Stärkung anti-israelischer oder sogar antisemitischer Einstellungen beigetragen hat, so war dies eher der Erzeugung von Reaktanz geschuldet als einem anti-israelischen Bias der Berichterstattung.

    2007-12-01

    Full Text Available Since the restoration of democracy, Spain’s successive governments have been noted for their favourable stance toward the issue of Palestine and their support for the creation of a sovereign independent state in the territories that Israel occupied during the Six-Day War. Yasser Arafat’s visit to Spain in the time of the UCD, the holding of the Madrid Conference during the term of government of the PSOE and the designation of Miguel Ángel Moratinos as the EU’s special envoy for the Peace Process during the Partido Popular’s term of government are some of the landmarks that have expressed this exemplary relationship between the Spanish State and the Palestine question. However, the victory of Hamas in the legislative elections of 25 January 2006 radically changed the situation, as it led to Rodríguez Zapatero’s government joining the international boycott of the new Islamist executive; even so, the Spanish government clearly maintained its support for restarting the Peace Process, in the form of its backing for Mahmud Abbas, the President of the Palestine Authority. The armed conflict in Gaza in June 2007 which led to the Islamists retaking the Gaza Strip and the formation of a new government in the West Bank led by the technocrat Salam Fayad served to normalise the situation, given that it encouraged the raising of international sanctions and a return to normality in Spanish-Palestine relations.

  19. Ammonia stripping of biologically treated liquid manure.

    Alitalo, Anni; Kyrö, Aleksis; Aura, Erkki

    2012-01-01

    A prerequisite for efficient ammonia removal in air stripping is that the pH of the liquid to be stripped is sufficiently high. Swine manure pH is usually around 7. At pH 7 (at 20°C), only 0.4% of ammonium is in ammonia form, and it is necessary to raise the pH of swine slurry to achieve efficient ammonia removal. Because manure has a very high buffering capacity, large amounts of chemicals are needed to change the slurry pH. The present study showed that efficient air stripping of manure can be achieved with a small amount of chemicals and without strong bases like NaOH. Slurry was subjected to aerobic biological treatment to raise pH before stripping. This facilitated 8 to 32% ammonia removal without chemical treatment. The slurry was further subjected to repeated cycles of stripping with MgO and Ca(OH)(2) additions after the first and second strippings, respectively, to raise slurry pH in between the stripping cycles. After three consecutive stripping cycles, 59 to 86% of the original ammonium had been removed. It was shown that the reduction in buffer capacity of the slurry was due to ammonia and carbonate removal during the stripping cycles.

    The LHCb experiment faces a major challenge from the large amounts of data received while the LHC is running. The ability to sort this information in a useful manner is important for working groups to perform physics analyses. Both hardware and software triggers are used to decrease the data rate and then the stripping process is used to sort the data into streams and further into stripping lines. This project studies the hundreds of stripping lines to look for overlaps between them in order to make the stripping process more efficient.

    The 'KATOD-1', a 16-channels readout ASIC, has been designed to perform tests of P3 and P4 full-scale prototypes of the cathode strip chamber for the ME1/1 forward muon station of the Compact Muon Solenoid (CMS) experiment. The ASIC channel consists of two charge-sensitive preamplifiers, a three-stage shaper with cancellation, and an output driver. The ASIC is instrumented with control of gain, in the range of (-4.2 : +5.0) mV/fC, and control of output pulse-shape. The equivalent input noise is equal to 2400 e with the slope of 12 e/pF for detector capacity up to 200 pF. The peaking time is 100 ns for the chamber signal. The ASIC has been produced by a microwave Bi-jFET technology

  4. One flag, two rallies: Mechanisms of public opinion in Israel during the 2014 Gaza war.

    Feinstein, Yuval

    2018-01-01

    In Israel, public reaction to the 2014 Gaza war included massive support for the military operation and a sharp increase in the popularity of Prime Minister Netanyahu. To understand what caused these "rally-round-the-flag" (RRTF) effects, panel data were collected from a representative sample of the Jewish majority in Israel during and after the war. The article integrate empirical and theoretical arguments from public opinion studies, and from social and political psychology, to contextualize and guide the analysis. The results reveal that perceived threat to collective security produced two simultaneous rally outcomes through distinct processes: First, increased identification with the ethno-national Jewish group led to a rally behind Israel's prime minister. Second, anger toward Hamas and sentiment of national superiority, which was activated by increased ethno-national identification, produced a rally behind the military operation. In addition to explaining its specific empirical case, this study makes three broader contributions. First, it extends the investigation of the RRTF phenomenon in wartime beyond the popularity of the head of the state (the focus of most previous studies) by also examining levels of support for the use of military power. Second, it reveals some of the mechanisms through which distinct elements of popular nationalism mediate the relationship between war events and heterogeneous rally effects. Third, this study shows that the mechanisms that have been detected in studies of individual attitudes and behavior in small groups under conditions of perceived threat or competition can help explain the behavior of these individuals as members of larger, imagined national communities during war.

    Knowledge of groundwater recharge constitutes a valuable tool for sustainable management in karst systems. In this respect, a quantitative evaluation of groundwater recharge can be considered a pre-requisite for the optimal operation of groundwater resources systems, particular for semi-arid areas. This paper demonstrates the processes affecting recharge in Palestine aquifers. The Central Western Catchment is one of the main water supply sources in the West Bank. Quantification of potential recharge rates are estimated using chloride mass balance (CMB) and empirical recharge equations over the catchment. The results showing the spatialized recharge rate, which ranges from 111-216 mm/year, representing 19-37% of the long-term mean annual rainfall. Using Water Balance models and climatological data (e. g. solar radiation, monthly temperature, average monthly relative humidity and precipitation), actual evapotranspiration (AET) is estimated. The mean annual actual evapotranspiration was about 66-70% of precipitation.

    2012-05-01

    Information about the rate of smoking and factors associated with initiating and maintaining the behaviour is scarce in Palestine. The aim of this study was to explore the rate of and attitudes towards smoking among An-Najah National University students. During spring 2010, a questionnaire adopted from the Global Health Professionals Survey and the Global Youth Tobacco Survey was administered to 954 randomly selected full-time students. Overall 34.7% of the study sample were cigarette or waterpipe smokers, and this rate was higher among males than females (52.7% versus 16.5%). In logistic regression analysis, sex (male), type of college (humanities), older age and higher family income were predictors of current smoking status. Smokers had more negative attitudes to banning smoking in public areas on campus and to education about the harmful effects of smoking. Antismoking programmes with special attention to males and students in humanities are badly needed.

  7. Stillness and Motion: Depicting the Urban Landscape of Palestine in the 19th Century

    2013-12-01

    Full Text Available This paper aims at offering valuable insights into the complex encounter between 19th-century Western travelers and the urban landscape of Palestine. The first part shows that, despite their efforts to distance themselves from the religious overtones of their predecessors, visitors tended to shove aside what they considered as ‘inauthentic’ or the product of acculturation in favor of a more conventional portrayal drawing on biblical imagery. This idealized vision was bound to struggle with disappointment, and the second part of this paper looks at how the representations of the city moved in the course of the 19th century from a purely pictorial transposition to a more practical and informed understanding of otherness. Travel writers began to devote considerable portions of their narratives to various aspects of life in the oriental town, while still predominately focusing on what they viewed as exotic and remote in comparison to European, and to a larger extent, Western culture.

  10. Mechanical behaviour of a creased thin strip

    2018-02-01

    Full Text Available In this study the mechanical behaviour of a creased thin strip under opposite-sense bending was investigated. It was found that a simple crease, which led to the increase of the second moment of area, could significantly alter the overall mechanical behaviour of a thin strip, for example the peak moment could be increased by 100 times. The crease was treated as a cylindrical segment of a small radius. Parametric studies demonstrated that the geometry of the strip could strongly influence its flexural behaviour. We showed that the uniform thickness and the radius of the creased segment had the greatest and the least influence on the mechanical behaviour, respectively. We further revealed that material properties could dramatically affect the overall mechanical behaviour of the creased strip by gradually changing the material from being linear elastic to elastic-perfect plastic. After the formation of the fold, the moment of the two ends of the strip differed considerably when the elasto-plastic materials were used, especially for materials with smaller tangent modulus in the plastic range. The deformation patterns of the thin strips from the finite element simulations were verified by physical models made of thin metal strips. The findings from this study provide useful information for designing origami structures for engineering applications using creased thin strips.

  12. Health journalism in the service of power: 'moral complacency' and the Hebrew media in the Gaza-Israel conflict.

    Birenbaum-Carmeli, Daphna

    2014-05-01

    The power of health news as a vehicle in the production of meaning in the service of power is the core of this article. Tracking the media coverage of a medical service, it shows how a routine practice can be invoked at a time of armed conflict so as to enhance a benevolent state image. The case at hand is the medical treatment of Gaza children in Israeli hospitals. A series of Internet searches revealed a group of publications on the subject in the Hebrew media, during and shortly after Israel's assault on Gaza in the winter of 2008-2009. In the press articles the treatments were invariably constituted as the epitome of Israel's compassion towards the enemy's children. This image relied, however, on a simultaneous silencing of other aspects of these treatments, which would have challenged this image. The monolithic depictions give rise to the notion of reversed moral panic or 'moral complacency', wherein the media amplifies a little-known social phenomenon into an epitome of societal values and charges it with significance on a national scale. The article ends with considering some features that possibly render health news an especially convenient domain for state-supportive media presentations. © 2014 The Author.

  13. CMS Silicon Strip Tracker Performance

    CERN Document Server

    Agram, Jean-Laurent

    2012-01-01

    The CMS Silicon Strip Tracker (SST), consisting of 9.6 million readout channels from 15148 modules and covering an area of 198 square meters, needs to be precisely calibrated in order to correctly reconstruct the events recorded. Calibration constants are derived from different workflows, from promptly reconstructed events with particles as well as from commissioning events gathered just before the acquisition of physics runs. The performance of the SST has been carefully studied since the beginning of data taking: the noise of the detector, data integrity, signal-over-noise ratio, hit reconstruction efficiency and resolution have been all investigated with time and for different conditions. In this paper we describe the reconstruction strategies, the calibration procedures and the detector performance results from the latest CMS operation.

    An ultrasonic inspection system was assembled to inspect the JBK-75 stainless steel sheath material (for the Large Coil Project) for the Westinghouse-Airco superconducting magnet program. The mechanical system provided for handling the 180-kg (400-lb) coils of strip material [1.6 mm thick by 78 mm wide by 90 to 120 m long (0.064 by 3.07 in. by 300 to 400 ft)], feeding the strip through the ultrasonic inspection and cleaning stations, and respooling the coils. We inspected 54 coils of strip for both longitudinal and laminar flaws. Simulated flaws were used to calibrate both inspections. Saw-cut notches [0.28 mm deep (0.011 in., about 17% of the strip thickness)] were used to calibrate the longitudinal flaw inspections; 1.59-mm-diam (0.063-in.) flat-bottom holes drilled halfway through a calibration strip were used to calibrate the laminar flaw tests

    The association between education and wealth, as fundamental determinants of health, and smoking is well-established. Yet, social inequalities have received little attention in the expanding field of tobacco research in the Arab region. In this study, we examine inequalities in cigarette smoking by education and wealth in four Arab countries. Utilizing the most recently available population-level data sets (Syria 2009 PAPFAM, Jordan 2012 DHS, Palestine 2010 Family Health Survey, and Lebanon 2004 PAPFAM), we tested the association between cigarette smoking and education and wealth-controlling for age, marital status, and region of residence-for each country, and among men and women depending on data availability. Cigarette smoking prevalence among Arab men is high- 51.3% in Syria, 39.7% in Palestine, and 42.1% in Lebanon; among women, prevalence is 8.4% in Syria, 10.9% in Jordan, and 24.3% Lebanon. Cigarette smoking shows the expected patterns inequalities by education among men in Syria, Palestine, and Lebanon, and among women in Jordan and Lebanon. On the other hand, wealth does not show a clear pattern in its association with cigarette smoking and, in some cases (men in Palestine and women in Syria) the behavioral risk is higher among the wealthiest. Available data from 2004-2012 show that cigarette smoking among men and women in the four Arab countries is predominant among those with limited access to education as a fundamental cause. The weak or absent negative association between wealth and cigarette smoking suggests that access to material resources does not precipitate a reduction in the consumption of tobacco.

    2017-09-01

    Conclusion: Potential medication dosing errors were high among pediatric hospitalized patients in Palestine. Younger patients, patients with lower body weight, who were prescribed higher number of medications and stayed in hospital for a longer time were more likely to have inappropriate doses, so these populations require special care. Many children were hospitalized for infectious causes and antibiotics were widely used. Strategies to reduce pediatric medication dosing errors are recommended.

    Sawyer, Craig; The ATLAS collaboration

    2017-01-01

    The module design for the Phase II Upgrade of the new ATLAS Inner Tracker (ITk) detector at the LHC employs integrated low mass assembly using single-sided flexible circuits with readout ASICs and a powering circuit incorporating control and monitoring of HV, LV and temperature on the module. Both readout and powering circuits are glued directly onto the silicon sensor surface resulting in a fully integrated, extremely low radiation length module which simultaneously reduces the material requirements of the local support structure by allowing a reduced width stave structure to be employed. Such a module concept has now been fully demonstrated using so-called ABC130 and HCC130 ASICs fabricated in 130nm CMOS technology to readout ATLAS12 n+-in-p silicon strip sensors. Low voltage powering for these demonstrator modules has been realised by utilising a DCDC powerboard based around the CERN FEAST ASIC. This powerboard incorporates an HV multiplexing switch based on a Panasonic GaN transistor. Control and monitori...

  19. Aeroelastic deformation of a perforated strip

    2018-01-01

    We perform a combined experimental and numerical investigation into the static deformation of perforated elastic strips under uniform aerodynamic loading at high-Reynolds-number conditions. The static shape of the porous strips, clamped either horizontally or vertically, is quantified as they are deformed by wind loading, induced by a horizontal flow. The experimental profiles are compared to numerical simulations using a reduced model that takes into account the normal drag force on the deformed surface. For both configurations (vertical and horizontal clamping), we compute the drag coefficient of the strip, by fitting the experimental data to the model, and find that it decreases as a function of porosity. Surprisingly, we find that, for every value of porosity, the drag coefficients for the horizontal configuration are larger than those of the vertical configuration. For all data in both configurations, with the exception of the continuous strip clamped vertically, a linear relation is found between the porosity and drag. Making use of this linearity, we can rescale the drag coefficient in a way that it becomes constant as a function of the Cauchy number, which relates the force due to fluid loading on the elastic strip to its bending rigidity, independently of the material properties and porosity of the strip and the flow speed. Our findings on flexible strips are contrasted to previous work on rigid perforated plates. These results highlight some open questions regarding the usage of reduced models to describe the deformation of flexible structures subjected to aerodynamic loading.

  20. Resurgent voices on the Israel-Palestine conflict: An appraisal of the alternative pathways towards resolving the conflict

    Directory of Open Access Journals (Sweden)

    Muhammad Yaseen Gada

    2016-07-01

    Full Text Available This review discusses the changing perceptions and resurgent voices towards the peaceful solution of the Israel-Palestine conflict. The review draws on studies, presented in five recent books, conducted by specialists in the area of (Israel-Palestine Conflict Resolution and International Studies. The question of whether the two-state solution is still feasible has caused much debate in various academic and public spheres over the last decade or so. The studies, conducted both inside and outside of Israel and Palestine, provide ample support that there have been growing dissenting voices and increasing peaceful resistance against the dominant view of the two-statism that divides territory and segregates the indigenous population with its history of harmony and coexistence. Despite their different views, the authors collectively maintain that in the current milieu of deadlock in the peace process, there is an urgent need to rethink and reformulate the two-state solution that perpetuates the Israeli hegemony and the unleashing of various discriminatory measures against the Palestinian population. Based on some key-common themes pervasive in the works under review, there is ample and growing support to the claim that the one-state solution offers a wider perspective of equal human rights and justice.

  1. A video strip chart program

    Jones, N.L.

    1994-01-01

    A strip chart recorder has been utilized for trend analysis of the Oak Ridge National Laboratory EN tandem since 1987. At the EN, the author could not afford the nice eight channel thermal pen recorder that was used at the 25 URC. He had to suffice with two channel fiber tip or capillary pen type recorders retrieved from salvage and maintained with parts from other salvaged recorders. After cycling through several machines that eventually became completely unserviceable, a search for a new thermal recorder was begun. As much as he hates to write computer code, he decided to try his hand at getting an old data acquisition unit, that had been retrieved several years ago from salvage, to meet his needs. A BASIC language compiler was used because time was not available to learn a more advanced language. While attempting to increase acquisition and scroll speed on the 6 MHz 80286 that the code was first developed on, it became apparent that scrolling only the first small portion of the screen at high speed and then averaging that region and histogramming the average provided both the speed necessary for capturing fairly short duration events, and a trend record without use of back scrolling and disk storage routines. This turned out to be quite sufficient

    PASTA is the 64 channel front-end chip, designed in a 110 nm CMOS technology to read out the strip sensors of the Micro Vertex Detector (MVD) of the PANDA experiment. This chip provides high resolution timestamp and deposited charge information by means of the time-over-threshold technique. Its working principle is based on a predecessor, the TOFPET ASIC, that was designed for medical applications. A general restructuring of the architecture was needed, in order to meet the specific requirements imposed by the physics programme of PANDA, especially in terms of radiation tolerance, spatial constraints, and readout in absence of a first level hardware trigger. The first revision of PASTA is currently under evaluation at the Forschungszentrum Jülich, where a data acquisition system dedicated to the MVD prototypes has been developed. This paper describes the main aspect of the chip design, gives an overview of the data acquisition system used for the verification, and shows the first results regarding the performance of PASTA.

    LLNL is collaborating with the UC Berkeley College of Engineering to develop and demonstrate a system of thermal remediation techniques for rapid cleanup of localized underground spills. Called dynamic stripping to reflect the rapid and controllable nature of the process, it will combine steam injection, direct electrical heating, and tomographic geophysical imaging in a cleanup of the LLNL gasoline spill. In the first eight months of the project, a Clean Site engineering test was conducted to prove the field application of the techniques. Tests then began on the contaminated site in FY 1992. This report describes the work at the Clean Site, including design and performance criteria, test results, interpretations, and conclusions. We fielded 'a wide range of new designs and techniques, some successful and some not. In this document, we focus on results and performance, lessons learned, and design and operational changes recommended for work at the contaminated site.

    In this work deuteron stripping reactions are studied using the distorted wave born approximation employing dirac phenomenological potentials. In 1982 Shepard and Rost performed zero-range dirac phenomenological stripping calculations and found a dramatic reduction in the predicted cross sections when compared with similar nonrelativistic calculations. We extend the earlier work by including full finite range effects as well as the deuteron's internal D-state. Results will be compared with traditional nonrelativistic approaches and experimental data at low energy.

    Johner, Alexander Marc; Pandis, Nikolaos; Dudic, Alexander; Kiliaridis, Stavros

    2013-04-01

    In this in-vitro study, we aimed to investigate the predictability of the expected amount of stripping using 3 common stripping devices on premolars. One hundred eighty extracted premolars were mounted and aligned in silicone. Tooth mobility was tested with Periotest (Medizintechnik Gulden, Modautal, Germany) (8.3 ± 2.8 units). The selected methods for interproximal enamel reduction were hand-pulled strips (Horico, Hapf Ringleb & Company, Berlin, Germany), oscillating segmental disks (O-drive-OD 30; KaVo Dental, Biberach, Germany), and motor-driven abrasive strips (Orthofile; SDC Switzerland, Lugano-Grancia, Switzerland). With each device, the operator intended to strip 0.1, 0.2, 0.3, or 0.4 mm on the mesial side of 15 teeth. The teeth were scanned before and after stripping with a 3-dimensional laser scanner. Superposition and measurement of stripped enamel on the most mesial point of the tooth were conducted with Viewbox software (dHal Software, Kifissia, Greece). The Wilcoxon signed rank test and the Kruskal-Wallis test were applied; statistical significance was set at alpha ≤ 0.05. Large variations between the intended and the actual amounts of stripped enamel, and between stripping procedures, were observed. Significant differences were found at 0.1 mm of intended stripping (P ≤ 0.05) for the hand-pulled method and at 0.4 mm of intended stripping (P ≤ 0.001 to P = 0.05) for all methods. For all scenarios of enamel reduction, the actual amount of stripping was less than the predetermined and expected amount of stripping. The Kruskal-Wallis analysis showed no significant differences between the 3 methods. There were variations in the stripped amounts of enamel, and the stripping technique did not appear to be a significant predictor of the actual amount of enamel reduction. In most cases, actual stripping was less than the intended amount of enamel reduction. Copyright © 2013 American Association of Orthodontists. Published by Mosby, Inc. All rights

To examine the empirical relationship between these explanatory variables and real (GDP growth the study adopted a standardized Cobb- Douglas production function by using the annual official data of the Palestinian Central Bureau of Statistics (PCBS, and applying the Ordinary least Square method (OLS and Second Order Auto Correlation Techniques. The empirical results of the model applied indicated that there is a positive relationship between the size of domestic working labour force, real gross domestic capital formation, real domestic exports and real gross domestic product( RGDP, and a negative relationship between real domestic imports of goods and services, and political instability and the real growth of (GDP. The study suggested several recommendations that can boost the level of growth, among them the most important one, is the urgent need for more investment in the economy as it leads to more formation of domestic capital which can count more in terms of economic growth in many ways.

    Full Text Available In arid and semi-arid regions, the availability of adequate water of appropriate quality has become a limiting factor for development. This paper aims to evaluate the potential for rainwater harvesting in the arid to semi-arid Faria Catchment, in the West Bank, Palestine. Under current conditions, the supply-demand gap is increasing due to the increasing water demands of a growing population with hydrologically limited and uncertain supplies. By 2015, the gap is estimated to reach 4.5 × 106 m3. This study used the process-oriented and physically-based TRAIN-ZIN model to evaluate two different rainwater harvesting techniques during two rainfall events. The analysis shows that there is a theoretical potential for harvesting an additional 4 × 106 m3 of surface water over the entire catchment. Thus, it is essential to manage the potential available surface water supplies in the catchment to save water for dry periods when the supply-demand gap is comparatively high. Then a valuable contribution to bridging the supply-demand gap can be made.

    Full Text Available This study aims to introduce Virtual Reality (VR techniques as a tool to develop an interactive environment for cultural heritage sites in Palestine; these sites have their own specific problems and challenges, which have significantly affected most of the existing sites and cause their continuous deterioration. The virtual replicas of these sites and landscapes can act as a medium for their preservation, documentation, interpretation and intervention, assisting in education, tourism and an increase in public awareness regarding their significant value. For this purpose, Hisham Palace in Jericho was chosen as a case study. The historical layers of Hisham Palace were studied and visualized using advanced 3D visualization techniques by applying a five-step approach to analyze and model different elements of the palace to assemble them at a later stage. This approach was implemented due to the critical condition of the physical remains and the insufficient literature on the history of the palace. As a result, a initial 3D virtual reality model was obtained, presented and discussed in a 3D immersive  environment at the Virtual Reality Lab (VR Lab at Birzeit University.

    Full Text Available This study examines the role that fan communities in Israel and Palestine play in the transcultural dissemination of Korean popular music, or “K-pop.” Based on in-depth interviews with fans, a survey of K-pop online communities, discourse analysis of online discussions, and participation in K-pop gatherings, this article examines the practice of K-pop, its localization and institutionalization, and its influence on the identities of fans. Special attention is given to the role of K-pop fans as cultural mediators who create necessary bridges between the music industry and local consumers and thus play a decisive role in globalizing cultures. Typically, literature on the globalization of popular culture either utilizes a top-down approach, depicting powerful media industries as making people across the world consume their products, or emphasizes a bottom-up resistance to the imposition of foreign cultures and values. This article suggests that popular culture consumption not only changes the lives of a few individuals but that these individuals may themselves play a decisive role in connecting globalized culture with local fandom.

    Energy conservation in utilities has played a vital role in improving energy efficiency in the industrial, commercial and residential sectors. The electrical energy consumption in Palestine has increased sharply in the past few years and achieved by the end of 2001 to 10% per year. It is expected that this percentage will increase to about 12% if the current political situation will end hopefully with peace. Modern energy efficient technologies are needed for the national energy policy. Such technologies are investigated in this paper. Implementing of a national 3 years project aiming at energy efficiency improvement in residential and industrial sectors as well as in public utilities, which include wide range of diversified audits and power measurements, had led to creating this paper. Measurement and audit results had shown that the total conservation potential in these sectors is around 15% of the total energy consumption. The associated costs of the investment in this field are relatively low and correspond to a pay back period varying in the range from 6 to 36 months. Consequently, the energy conservation policy will be seriously improved in the forthcoming years. It is estimated that 10% of the new energy purchasing capacity will be reduced accordingly

    Natural plants products are one of the famous and commonly utilized remedies used in fighting diseases. This study was conducted to evaluate antioxidant activity of plants commonly used in Palestine (Urtica urens, Rumex cyprius and Borago officinalis). Free radical scavenging activity method was evaluated by using 2,2-diphenyl-1-picryl-hydrazyl-hydrate. The result show that the overall antioxidant activity of Rumex cyprius was the highest among the plants, followed by Urtica urens, and Borago officinalis; respectively. The (IC(50)) values of the methanolic extracts were 29.70±0.60μg/ml, 5.07±0.49μg/ml, 39.92± 0.52 μg/ml for Urtica urens, Rumex cyprius and Borago officinalis respectively. The results of this study revealed that these edible plants have high antioxidant activity and therefore they can provide natural sources of antioxidants and can be useful in preventing various diseases including cancer. These exhibited properties propose that such plants extracts can possibly be used as natural preservatives in the food and pharmaceutical industries and further characterization of Rumex cyprius constituents is needed.

  18. Water Grabbing in Colonial Perspective: Land and Water in Israel/Palestine

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available 'Water grabbing' and 'land grabbing' have been referred to as a new colonialism, dispossessing small farmers and indigenous people of land and water for the sake of investors. The current 'grabbing' is driven by perceived scarcity of food and sustainable energy, and is enabled by global financial instruments and commodity speculation. In this paper, we argue that while in many ways different, the 'new colonialism' of land/water grabbing may be better understood through analysis of old colonialism. We use actor network and place modernisation theories to analyse the history and practice of Zionist land/water grabbing in Israel/Palestine as an ongoing remnant of old colonialism. While there are clearly unique aspects to this case, there are similarities in processes, such as the narrative of modernising 'barren', 'infertile', and 'undeveloped' land. The ongoing power imbalance in water management and access, the disproportionate burden on Palestinians of growing water scarcity, and the inability of technical fixes to address the problems of relative deprivation may be seen as cautionary tales for current 'water grabbing'.

    Value of information (VOI) analysis evaluates the benefit of collecting additional information to reduce or eliminate uncertainty in a specific decision-making context. It makes explicit any expected potential losses from errors in decision making due to uncertainty and identifies the “best” information collection strategy as one that leads to the greatest expected net benefit to the decision-maker. This study investigates the willingness to pay for groundwater quality monitoring in the Eocene Aquifer, Palestine, which is an unconfined aquifer located in the northern part of the West Bank. The aquifer is being used by 128,000 Palestinians to fulfill domestic and agricultural demands. The study takes into account the consequences of pollution and the options the decision maker might face. Since nitrate is the major pollutant in the aquifer, the consequences of nitrate pollution were analyzed, which mainly consists of the possibility of methemoglobinemia (blue baby syndrome). In this case, the value of monitoring was compared to the costs of treating for methemoglobinemia or the costs of other options like water treatment, using bottled water or importing water from outside the aquifer. And finally, an optimal monitoring network that takes into account the uncertainties in recharge (climate), aquifer properties (hydraulic conductivity), pollutant chemical reaction (decay factor), and the value of monitoring is designed by utilizing a sparse Bayesian modeling algorithm called a relevance vector machine.

    The energy situation in Palestine is somewhat unique when compared to other countries in the Middle East. There are virtually no available natural resources, and due to the ongoing political situation, the Palestinians rely (or have to rely) almost totally on Israel for their energy needs. This paper presents three energy supply alternatives for a remote village represented in PV system, diesel generator and electric grid. Design of these systems and the associated costs of their utilization are illustrated. Economic evaluation methods are used to compare the economic-effectiveness of these energy systems. The results show that, utilizing of PV systems for rural electrification in Palestine is economically more useful than using diesel generators or extension of the high voltage electric grid. The obtained results represents also a helpful reference for energy planers in Palestine and justify the consideration of PV systems more seriously. (orig.)

  1. Development of floating strip micromegas detectors

    Bortfeldt, Jonathan

    2014-04-28

    Micromegas are high-rate capable, high-resolution micro-pattern gaseous detectors. Square meter sized resistive strip Micromegas are foreseen as replacement of the currently used precision tracking detectors in the Small Wheel, which is part of the forward region of the ATLAS muon spectrometer. The replacement is necessary to ensure tracking and triggering performance of the muon spectrometer after the luminosity increase of the Large Hadron Collider beyond its design value of 10{sup 34} cm{sup -2}s{sup -1} around 2020. In this thesis a novel discharge tolerant floating strip Micromegas detector is presented and described. By individually powering copper anode strips, the effects of a discharge are confined to a small region of the detector. This reduces the impact of discharges on the efficiency by three orders of magnitude, compared to a standard Micromegas. The physics of the detector is studied and discussed in detail. Several detectors are developed: A 6.4 x 6.4 cm{sup 2} floating strip Micromegas with exchangeable SMD capacitors and resistors allows for an optimization of the floating strip principle. The discharge behavior is investigated on this device in depth. The microscopic structure of discharges is quantitatively explained by a detailed detector simulation. A 48 x 50 cm{sup 2} floating strip Micromegas is studied in high energy pion beams. Its homogeneity with respect to pulse height, efficiency and spatial resolution is investigated. The good performance in high-rate background environments is demonstrated in cosmic muon tracking measurements with a 6.4 x 6.4 cm{sup 2} floating strip Micromegas under lateral irradiation with 550 kHz 20 MeV proton beams. A floating strip Micromegas doublet with low material budget is developed for ion tracking without limitations from multiple scattering in imaging applications during medical ion therapy. Highly efficient tracking of 20 MeV protons at particle rates of 550 kHz is possible. The reconstruction of the

    Full Text Available The paper discusses the issue of obtaining high quality cast workpieces of magnesium alloys produced by strip roll-casting. Producing strips of magnesium alloys by combining the processes of casting and rolling when liquid melt is fed continuously to fast rolls is quite promising and economic. In the process of sheet stamping considerable losses of metal occur on festoons formed due to anisotropy of properties of foil workpiece, as defined by the macro- and microstructure and modes of rolling and annealing. The principal causes of anisotropic mechanical properties of metal strips produced by the combined casting and rolling technique are the character of distribution of intermetallic compounds in the strip, orientation of phases of metal defects and the residual tensions. One of the tasks in increasing the output of fit products during stamping operations consists in minimizing the amount of defects. To lower the level of anisotropy in mechanical properties various ways of treating the melt during casting are suggested. Designing the technology of producing strips of magnesium alloys opens a possibility of using them in automobile industry to manufacture light-weight body elements instead of those made of steel.

    We review progress in the development and applications of superconducting nano-strip particle detectors. Particle detectors based on superconducting nano-strips stem from the parent devices developed for single photon detection (SSPD) and share with them ultra-fast response times (sub-nanosecond) and the ability to operate at a relatively high temperature (2–5 K) compared with other cryogenic detectors. SSPDs have been used in the detection of electrons, neutral and charged ions, and biological macromolecules; nevertheless, the development of superconducting nano-strip particle detectors has mainly been driven by their use in time-of-flight mass spectrometers (TOF-MSs) where the goal of 100% efficiency at large mass values can be achieved. Special emphasis will be given to this case, reporting on the great progress which has been achieved and which permits us to overcome the limitations of existing mass spectrometers represented by low detection efficiency at large masses and charge/mass ambiguity. Furthermore, such progress could represent a breakthrough in the field. In this review article we will introduce the device concept and detection principle, stressing the peculiarities of the nano-strip particle detector as well as its similarities with photon detectors. The development of parallel strip configuration is introduced and extensively discussed, since it has contributed to the significant progress of TOF-MS applications. (paper)

    In order to use Airborne Gamma-ray Spectrometry (AGS) for contamination mapping, for source search etc. one must to be able to eliminate the contribution to the spectra from natural radioactivity. This in general is done by a stripping technique. The parameters for performing a stripping have until recently been measured by recording gamma spectra at special calibration sites (pads). This may be cumbersome and the parameters may not be correct when used at low gamma energies for environmental spectra. During 2000-2001 DTU tested with success a new technique for Carborne Gamma-ray Spectrometry (CGS) where the spectra from the surveyed area (or from a similar area) were used for calculating the stripping parameters. It was possible to calculate usable stripping ratios for a number of low energy windows - and weak source signals not detectable by other means were discovered with the ASS technique. In this report it is shown that the ASS technique also works for AGS data, and it has been used for recent Danish AGS tests with point sources. (Check of calibration of AGS parameters.) By using the ASS technique with the Boden data (Barents Rescue) an exercise source was detected that has not been detected by any of the teams during the exercise. The ASS technique therefore seems to be better for search for radiation anomalies than any other method known presently. The experiences also tell that although the stripping can be performed correctly at any altitude there is a variation of the stripping parameters with altitude that has not yet been quite understood. However, even with the oddly variations the stripping worked as expected. It was also observed that one might calculate a single common set of usable stripping factors for all altitudes from the entire data set i.e. some average a, b and c values. When those stripping factors were used the stripping technique still worked well. (au)

    Generic substitution in several countries has become a common practice. Besides, it is considered as a major cost minimizing strategy meant to contain pharmaceutical expenditure without compromising healthcare quality. However, the safety and quality issues of generic products are of top concerns of general practitioners and health work professionals. This study aimed to investigate community pharmacist's knowledge, attitudes and practices toward generic medicines in Palestine. This study was a cross-sectional observational study employing a self-administered questionnaire. The questionnaire was of four main sections: demographic and practice details of the participants, knowledge, attitudes and the influencing factors related to selection and dispensing of generic medicines. A convenience sampling technique was implemented in this study in which the data collection form was distributed in West Bank- Palestine among a set of practicing pharmacists. Mann-Whitney-U or Kruskal-Wallis tests were used to comparison of different issues as appropriate. P-values of medicines was (5.91 ± 1.27) where the highest score was 8 of 10. Knowledge score was not significantly influenced by any of the socio-demographic characteristics. Our data showed that most of included pharmacists in the study (95.4%) agreed that health authorities should implement bioequivalence policies prior to marketing approval of generics, while 87.4% of participants agreed that they should be given the right to substitute generics and the majority (62.3%) support generic substitution for brand name drugs in all cases when a generic is available The main two factors affect pharmacists' selection and dispensing of generic medicines are personal faith in the product (86.1%) and cost effectiveness of generic medicines (84.1%). Generic medicines substitution among pharmacists is widespread and prevalent. Our data found that participant pharmacists in Palestine had basic knowledge with regards to generic

    We present results of the analysis of a galaxy redshift catalog made at the 6-m telescope by Karachentsev and Kopylov (1990. Mon. Not. R. astr. Soc., 243, 390). The catalog covers a long narrow strip on the sky (10 arcmin by 63 0 ) and lists 283 galaxies up to limiting blue magnitude m B = 17.6. The strip goes through the core of Coma cluster and this is called the 'Coma strip' catalog. The catalog is almost two times deeper than the CfA redshift survey and creates the possibility of studying the galaxy distribution on scales of 100-250 Mpc. Due to the small number of galaxies in the catalog, we were able to estimate only very general and stable parameters of the distribution. (author)

  8. Wokker. Notes on a Surrealist comic strip

    Full Text Available This essay explores the creation and development of a British comic strip, Wokker (1971-1999, and its connections with the surrealist movement. Although the strip is remarkable for its content and formalist properties, it remains obscure both because of its publishing circumstances, and because it does not fit easily into a history of comics. Rather it can be argued that its conceptual roots can be traced to the artistic ferment that happened in Paris in the 1920s (with Breton as a key reference point, and that it represents a very English, and late-flowering, example of the surrealist idea.

    A section of the LEP beam pipe. This is the chamber in which LEP's counter-rotating electron and positron beams travel. It is made of lead-clad aluminium. The beams circulate in the oval cross-section part of the chamber. In the rectangular cross-section part, LEP's innovative getter-strip vacuum pump is installed. After heating to purify the surface of the getter, the strip acts like molecular sticky tape, trapping any stray molecules left behind after the accelerator's traditional vacuum pumps have done their job.

    The Silicon Strip Tracker (SST) of the CMS experiment is, with 9.6 million readout channels, the largest strip tracker ever built. In order to correctly interpret and reconstruct the events recorded it needs to be precisely calibrated, thus ensuring that it fully contributes to the physics research program of the CMS experiment. In 2009 and 2010, the performance of the SST has been carefully studied using cosmic muons and tracks from proton-proton collisions at centre-of-mass energies of 900 GeV, 2.36 TeV and 7 TeV. In this paper, we present some results of the detector performance.

    Headache is one of the most common complaints in clinical practice. Few studies regarding headache in university students have been conducted in the Middle East. The objective of this study was to explore the prevalence, clinical characteristics, triggering factors and treatment options of headaches in university undergraduate students in Palestine/Middle East. Data were collected by interviewing a sample of 1900 students. The Headache Assessment Quiz was used to measure quality and severity of headache and to collect data on triggering factors and symptom management. A total of 1808 (95.2%) reported having at least one headache episode in the previous year. A positive family history of headache was found in 40% of students. The prevalence rate of frequent headache (tow or more episodes/month) was found in 1096 (60.9%) students; 613 women (55.9%). Of those having frequent headaches, 228 (20.8%) experienced moderate to severe episodes, 341 (31.2%) had pulsating, throbbing and pounding pain, and 274 (25%) had unilateral pain. The most common triggering factors among students with frequent headaches were: tension/stress (78.2%) and sleep deprivation (75.4%). Less than 5% of students sought medical assistance during headache episodes. Most students (79.1%) reported self-therapy with a single analgesic (53.4%), herbs (10.2%) or combination (15.5%), while 20.9% reported using no medication of any type to decrease pain. Paracetamol (48.5%) followed by ibuprofen (4.9%) were the most commonly used non-prescription analgesic drugs. Headache is a prevalent symptom in the college age population. Further research is needed to determine the prevalence of specific types of headaches. Healthcare providers are required to educate this population as well as to assist students in properly diagnosing and treating headache types.

    Full Text Available Occupational hazards, exposure to blood and body fluids (BBF accidents and safety precautions constitute an important public health issue. We assessed the prevalence and determinants of exposure to occupational hazards among nurses, and their knowledge of occupational safety precautions. In a cross-sectional study, we surveyed 332 nurses working in 4 hospitals, Nablus, West Bank, Palestine, by a questionnaire. Bivariate analysis tested the associations between ever exposure and the high likelihood of BBF exposure and the independent socio-demographic and occupational variables. Binary logistic regression analysis was used to assess the associations between the same two exposures and selected independent variables (those significant in the bivariate analysis. Prevalence of ever exposure to BBF was 51.7%, and was associated with working in private and charitable hospitals (OR 2.62, 2.68, respectively, having 4–6 family members (OR 0.52 and “nursing” being as one's top career choice at university (OR 0.48. The prevalence of high likelihood of BBF exposure was 62.2%, and was associated with working in charitable and private hospitals (OR 7.81, 2.43, respectively and “nursing” being as one's top career choice (OR 0.57. Regarding knowledge, most respondents believed it is necessary to enact laws and regulations regarding occupational safety precautions, reported the use of sharps containers, immediate disinfection after an accident, reporting an accident, and using personal protective equipment. Nurses had adequate knowledge of the risks of their hospital work. Nevertheless, they exhibited high prevalence of exposure to BBF accidents. Future studies are needed to re-evaluate existing occupational safety guidelines in hospitals, establish monitoring and evaluation protocols for health care workers' adherence to the guidelines, and institute well-defined policies for reporting occupational injury incidents so these can be handled appropriately.

    2018-02-01

    Radiation doses to patients resulting from chest X-ray examinations were evaluated in four medical centers in the West Bank and East Jerusalem-Palestine. Absorbed organ and effective doses were calculated for a total of 428 adult male and female patients by using commercially available Monte Carlo based softwares; CALDOSE-X5 and PCXMC-2.0, and hermaphrodite mathematical adult phantoms. Patients were selected randomly from medical records in the time period from November 2014 to February 2015. A database of surveyed patients and exposure factors has been established and includes: patient's height, weight, age, gender, X-ray tube voltage, electric current (mAs), examination projection (anterior posterior (AP), posterior anterior (PA), lateral), X-ray tube filtration thickness in each X-ray equipment, anode angle, focus to skin distance and X-ray beam size. The average absorbed doses in the whole body from different projections were: 0.06, 0.07 and 0.11 mGy from AP, PA and lateral projections, respectively. The average effective dose for all surveyed patients was 0.14 mSv for all chest X-ray examinations and projections in the four investigated medical centers. The effect of projection geometry was also investigated. The average effective doses for AP, PA and lateral projections were 0.14, 0.07 and 0.22 mSv, respectively. The collective effective dose estimated for the exposed population was ~60 man-mSv. © The Author 2017. Published by Oxford University Press. All rights reserved.

    Full Text Available Abstract Background Radon gas is considered as a main risk factor for lung cancer and found naturally in rock, soil, and water. The objective of this study was to determine the radon level in the drinking water sources in Nablus city in order to set up a sound policy on water management in Palestine. Methods This was a descriptive study carried out in two phases with a random sampling technique in the second phase. Primarily, samples were taken from 4 wells and 5 springs that supplied Nablus city residents. For each source, 3 samples were taken and each was analyzed in 4 cycles by RAD 7 device manufactured by Durridge Company. Secondly, from the seven regions of the Nablus city, three samples were taken from the residential tap water of each region. Regarding the old city, ten samples were taken. Finally, the mean radon concentration value for each source was calculated. Results The mean (range concentration of radon in the main sources were 6.9 (1.5-23.4 Becquerel/liter (Bq/L. Separately, springs and wells' means were 4.6 Bq/L and 9.5 Bq/L; respectively. For the residential tap water in the 7 regions, the results of the mean (range concentration values were found to be 1.0 (0.9-1.3 Bq/L. For the old city, the mean (range concentration values were 2.3 (0.9-3.9 Bq/L. Conclusions Except for Al-Badan well, radon concentrations in the wells and springs were below the United State Environmental Protection Agency maximum contaminated level (U.S EPA MCL. The level was much lower for tap water. Although the concentration of radon in the tap water of old city were below the MCL, it was higher than other regions in the city. Preventive measures and population awareness on radon's exposure are recommended.

    The death notification forms (DNFs) are important documents. Thus, inability to fill it properly by physicians will affect the national mortality report and, consequently, the evidence-based decision making. The errors in filling DNFs are common all over the world and are different in types and causes. We aimed to evaluate the quality of DNFs in terms of completeness and types of errors in the cause of death section. A descriptive study was conducted to review 2707 DNFs in North West Bank/Palestine during the year 2012 using data abstraction sheets. SPSS 17.0 was used to show the frequency of major and minor errors committed in filling the DNFs. Surprisingly, only 1% of the examined DNFs had their cause of death section filled completely correct. The immediate cause of death was correctly identified in 5.9% of all DNFs and the underlying cause of death was correctly reported in 55.4% of them. The sequence was incorrect in 41.5% of the DNFs. The most frequently documented minor error was "Not writing Time intervals" error (97.0%). Almost all DNFs contained at least one minor or major error. This high percentage of errors may affect the mortality and morbidity statistics, public health research and the process of providing evidence for health policy. Training workshops on DNF completion for newly recruited employees and at the beginning of the residency program are recommended on a regular basis. As well, we recommend reviewing the national DNFs to simplify it and make it consistent with updated evidence-based guidelines and recommendation.

  20. Parental self-feeding effects on parental care levels and time allocation in Palestine sunbirds.

    Directory of Open Access Journals (Sweden)

    Shai Markman

    Full Text Available The trade-off between parents feeding themselves and their young is an important life history problem that can be considered in terms of optimal behavioral strategies. Recent studies on birds have tested how parents allocate the food between themselves and their young. Until now the effect of food consumption by parent birds on their food delivery to their young as well as other parental activities has rarely been studied. I have previously shown that parent Palestine sunbirds (Nectarinia osea will consume nectar and liquidized arthropods from artificial feeders. However, they will only feed their young with whole arthropods. This provided a unique opportunity to experimentally manipulate the food eaten by parents independent of that fed to their offspring. Here, I hypothesized that parents invest in their current young according to the quality of food that they themselves consume. Breeding pairs with two or three nestlings were provided with feeders containing water (control, sucrose solution (0.75 mol or liquidized mealworms mixed with sucrose solution (0.75 mol. As food quality in feeders increased (from water up to liquidized mealworms mixed with sucrose solution: 1 Parents (especially females increased their food delivery of whole arthropod prey to their young. 2 Only males increased their nest guarding effort. Nestling food intake and growth rate increased with increasing food quality of parents and decreasing brood size. These results imply that increasing the nutrient content of foods consumed by parent sunbirds allow them to increase the rate at which other foods are delivered to their young and to increase the time spent on other parental care activities.

    2015-01-01

    A critical component of the DNA Medicine Institute's Reusable Handheld Electrolyte and Lab Technology for Humans (rHEALTH) sensor are nanoscale test strips, or nanostrips, that enable multiplexed blood analysis. Nanostrips are conceptually similar to the standard urinalysis test strip, but the strips are shrunk down a billionfold to the microscale. Each nanostrip can have several sensor pads that fluoresce in response to different targets in a sample. The strips carry identification tags that permit differentiation of a specific panel from hundreds of other nanostrip panels during a single measurement session. In Phase I of the project, the company fabricated, tested, and demonstrated functional parathyroid hormone and vitamin D nanostrips for bone metabolism, and thrombin aptamer and immunoglobulin G antibody nanostrips. In Phase II, numerous nanostrips were developed to address key space flight-based medical needs: assessment of bone metabolism, immune response, cardiac status, liver metabolism, and lipid profiles. This unique approach holds genuine promise for space-based portable biodiagnostics and for point-of-care (POC) health monitoring and diagnostics here on Earth.

    Response of three 150x150x450mm short reinforced concrete (RC) columns confined with different types of confining steel was investigated. Standard stirrups, strips and stapled strips, each having same cross-sectional area, were employed as confining steel around four comer column bars. Experimental work was aimed at probing into the affect of stapled strip confinement on post elastic behavior and ductility level under cyclic axial load. Ductility ratios, strength enhancement factor and core concrete strengths were compared to study the affect of confinement. Results indicate that strength enhancement in RC columns due to strip and stapled strip confinement was not remarkable as compared to stirrup confined column. It was found that as compared to stirrup confined column, stapled strip confinement enhanced the ductility of RC column by 183% and observed axial capacity of stapled strip confined columns was 41 % higher than the strip confined columns.

    2014-01-01

    Full Text Available A novel pattern reconfigurable antenna concept utilizing rectangular dielectric resonator antenna (DRA placed over dielectric substrate backed by a ground plane is presented. A dual strip excitation scheme is utilized and both excitation strips are connected together by means of a 50 Ω microstrip feed network placed over the substrate. The four vertical metallic parasitic strips are placed at corner of DRA each having a corresponding ground pad to provide a short/open circuit between the parasitic strip and antenna ground plane, through which a shift of 90° in antenna radiation pattern in elevation plane is achieved. A fractional bandwidth of approximately 40% at center frequency of 1.6 GHz is achieved. The DRA peak realized gain in whole frequency band of operation is found to be above 4 dB. The antenna configuration along with simulation and measured results are presented.

    Superconducting strip-line detectors (SSLDs) are an important emerging technology for the detection of single molecules in time-of-flight mass spectrometry (TOF-MS). We present an experimental investigation of a SSLD laid out in a parallel configuration, designed to address selected single strip-lines operating in the single-strip switch regime. Fast laser pulses were tightly focused onto the device, allowing controllable nucleation of a resistive region at a specific location and study of the subsequent device response dynamics. We observed that in this regime, although the strip-line returns to the superconducting state after triggering, no effective recovery of the bias current occurs, in qualitative agreement with a phenomenological circuit simulation that we performed. Moreover, from theoretical considerations and by looking at the experimental pulse amplitude distribution histogram, we have the first confirmation of the fact that the phenomenological London model governs the current redistribution in these large area devices also after detection events.

    The planned HL-LHC (High Luminosity LHC) is being designed to maximise the physics potential of the LHC with 10 years of operation at instantaneous luminosities of \\mbox{$7.5\\times10^{34}\\;\\mathrm{cm}^{-2}\\mathrm{s}^{-1}$}. A consequence of this increased luminosity is the expected radiation damage requiring the tracking detectors to withstand hadron equivalences to over $1x10^{15}$ 1 MeV neutron equivalent per $cm^{2}$ in the ATLAS Strips system. The silicon strip tracker exploits the concept of modularity. Fast readout electronics, deploying 130nm CMOS front-end electronics are glued on top of a silicon sensor to make a module.

    Stuart Reigeluth

    2011-04-01

    Full Text Available In the Arab-Israeli conflict, the creation and maintaining of resistance groups, as well as their recurring confrontations with Israel, take place with greater intensity in the Palestinian territories and Lebanon. In the same way that the Palestine Islamic Resistance Movement (Hamas was born out of the military occupation of the West Bank, Jerusalem and the Gaza Strip, the Lebanese Party of God (Hezbollah emerged to counteract the presence of Israel and her allies in the south of Lebanon. The pressure exerted on Israel to leave the south of Lebanon (2000 and the Gaza Strip (2005 engendered massive popular support which resulted in victories in both municipal and national elections. Both armed Islamist groups shifted towards increasingly passive policies, though at the same time they continue to be condemned to ostracism by the United States and Europe, the rupture with the secular parties became deeper, and thus the solution was deferred: the creation of coalition governments respected by their own peoples. Today, this continues to be the greatest challenge to establishing democracy in the Middle East; in no other place is this more acute than in Palestine and the Lebanon.

  19. Bird community response to filter strips in Maryland

    Filter strips are strips of herbaceous vegetation planted along agricultural field margins adjacent to streams or wetlands and are designed to intercept sediment, nutrients, and agrichemicals. Roughly 16,000 ha of filter strips have been established in Maryland through the United States Department of Agriculture's Conservation Reserve Enhancement Program. Filter strips often represent the only uncultivated herbaceous areas on farmland in Maryland and therefore may be important habitat for early-successional bird species. Most filter strips in Maryland are planted to either native warm-season grasses or cool-season grasses and range in width from 10.7 m to 91.4 m. From 2004 to 2007 we studied the breeding and wintering bird communities in filter strips adjacent to wooded edges and non-buffered field edges and the effect that grass type and width of filter strips had on bird community composition. We used 5 bird community metrics (total bird density, species richness, scrub-shrub bird density, grassland bird density, and total avian conservation value), species-specific densities, nest densities, and nest survival estimates to assess the habitat value of filter strips for birds. Breeding and wintering bird community metrics were greater in filter strips than in non-buffered field edges but did not differ between cool-season and warm-season grass filter strips. Most breeding bird community metrics were negatively related to the percent cover of orchardgrass (Dactylis glomerata) in ???1 yr. Breeding bird density was greater in narrow (60 m) filter strips. Our results suggest that narrow filter strips adjacent to wooded edges can provide habitat for many bird species but that wide filter strips provide better habitat for grassland birds, particularly obligate grassland species. If bird conservation is an objective, avoid planting orchardgrass in filter strips and reduce or eliminate orchardgrass from filter strips through management practices. Copyright ?? 2011 The

    Herbal self-therapy is a common practice among Palestinians. However, no published data are available on herbal self-therapy in the Middle East in general, and in Palestine in particular. This study was conducted to (1) determine the extent of herbal self-therapy among university students, (2) investigate the different types of herbal remedies used and (3) investigate the correlates and reasons associated with such practices. This cross-sectional, descriptive study was carried out using a structured questionnaire that contained five sections: (1) demographics; (2) medication knowledge and self-care orientation; (3) types of herbal remedies used; (4) clinical conditions treated; and finally, (5) the reasons reported by students for herbal self-therapy practice. Pearson chi(2), multiple logistic regression and one-way ANOVA were performed using SPSS 13 program. 33.9% of the respondents reported using herbal remedies in self-therapy. Female gender, students at medical colleges and those with high self-care orientation were significant predictive model for herbal use. Sage (Salvia fruticosa L.), chamomile (Chamaemelum nobile L.), anise (Pimpinella anisum L.), and thyme (Thymus vulgaris L.) were the most commonly utilized herbal remedies. The types of herbal remedies selected were significantly influenced by gender, but not by the level of medication knowledge or self-care orientation. Herbal remedies were used primarily for the treatment of headache, flu, menstrual pain and sore throat. The main motivating factor for using herbal remedies reported for using herbal remedies was simplicity of symptoms. Herbal self-therapy was a common practice among university students. Health care providers need to be aware of the students' self-therapy practices and need to have sufficient knowledge regarding herbs not simply because of the widespread use, but also because of significant reported side effects. Academics need to consider offering courses about herbal remedies to

    An application of treated sewage sludge on agricultural land has been widely accepted, as this method is simple and economical for disposal of wastewater residues. When applied properly on an agricultural land, sludge can replenish organic matter and nutrients in soil. Although sewage sludge has been used in agriculture in many parts of the world, its acceptability varies with different cultures and beliefs among farmers. Farmers' concerns on sludge use are primarily due to its anthropogenic origin, pollutants that it carries, a general perception of sewage being dirty, and its offensive odor. This paper aims to investigate farmers' perceptions on land application of treated sewage sludge on their farm. This study targeted two farming communities, namely, Anza and Beit Dajan villages, located in Jenin and Nablus districts in the West Bank, Palestine. In this study, a sample of 106 farmers were randomly selected and surveyed through a mixture of structured and open-ended questions. Results indicated that, overall, farmers have positive perceptions on land application of sludge. A majority of the farmers are in favor of the concept of sludge use when a planned wastewater treatment plant is constructed and it becomes operational. Results also indicate that a majority of the farmers are in favor of using sludge for fertilizing fruit trees, rather than growing vegetables and other plants in a greenhouse, and that many of them have knowledge of sludge properties and advantages and disadvantages of sludge use in agriculture. Despite the positive perceptions by the majority of farmers, a small fraction of the farmers are in disfavor of the use of sludge for the following reasons: psychological and social concerns, potential health risks, and their religious beliefs. Results further suggest that the land application of treated sewage sludge can be accepted by more farmers if the consumers are willing to buy agricultural products fertilized by sludge, sludge meets the public

  2. Development of maintenance composite priority index for buildings in Palestine: A pilot case study

    2017-11-01

    The current building maintenance practices in Palestine are not based on scientific systematic methods. Most of the municipalities use one criterion to define the maintenance priorities, which is the "worst-first" criterion. Therefore, the current practices in defining buildings maintenance plans are not dealing with the known phases that are generally followed, including those in establishing building inventories, building condition survey, detailed visual inspection, identification of the proper maintenance and rehabilitation measures, and setting priorities. Accordingly, the recent preparation of the Operation and Maintenance (O&M) Manual for Palestinian municipalities is an important step to guide them towards preparing and implementing their O&M priority-based plans, considering scare resources. During the course of preparation of the Manual, the proposed procedures were applied at ten pilot municipalities. This study aims to explore the outcome of the implementation of the 2014/2015 O&M buildings maintenance priorities at these municipalities through the development of maintenance composite priority index (PI). The new proposed priority index is a scientific tool that will identify the priority of maintenance buildings through using a systematic procedure instead of first worst one. To achieve this, analyses of the outcome of a questionnaire designed to collect relevant information from these municipalities was conducted. The maintenance priority index for buildings is calculated considering different indicators among them building status (condition), classification and importance of the building, number of beneficiaries (users), safety aspects (severity level in the building), and people complaints. The main component of the PI is the building condition index (BCI) which forms about 40% of the total weight. The physical inspection, which is the main input for calculating the BCI, is conducted on two levels; the primary level, and the secondary level. The

  3. An inquiry into socio-historical factors contributing to poverty within the Early Church in Palestine

    Directory of Open Access Journals (Sweden)

    Frederick Kakwata

    2015-11-01

    Full Text Available This article seeks to investigate the root causes of poverty in the early Christian community.The view that is put forward and argued in this article is that poverty was widespread in early Christianity with particular reference to the converted Jews in Palestine. This was the result of socio-historical factors, namely the Israelites’ contact with Canaanites during the conquest,and the implementation of the secular leadership paradigm derived from those paga n nations around Israel, which led to their subjugation under the oppressive and exploitative and economic structures of the Roman Empire. For that reason many believers, newly converted Jews, at that time were destitute and impoverished as they belonged to the lower classes in society. In spite of this state of affairs, the early Christians in Jerusalem seemed to have faced the challenges of poverty with a measure of success as can be attested by the statement ‘for there was no needy person amongst them …’ (Ac 4:34. ’n Ondersoek na sosio-historiese faktore wat tot armoede binne die vroeë Christelikekerk in Palestina bygedra het. Die doel van hierdie artikel is om die grondoorsake van armoede in die vroeë Christelike gemeenskap te ondersoek met spesifieke verwysing na die bekeerde Jode in Palestina. Die standpunt wat in hierdie artikel gestel en beredeneer word, is dat armoede algemeen in die vroeë Christendom voorgekom het. Dit was as gevolg van verskeie sosio-historiese faktore, waaronder die Israeliete se kontak met die Kanaäniete ná die inname, asook die instelling van die sekulêre paradigma oor leierskap wat Israel aan die naburige heidennasies ontleen het en wat op hulle verknegting onder die Romeinse Ryk se onderdrukkende en uitbuitende strukture uitgeloop het. ’n Groot aantal gelowiges, bekeerde Jode, was in daardie tyd behoeftig en armoedig omdat hulle deel van die laer klasse in die samelewing was. Tog, ten spyte van hierdie omstandighede, het die vroeë Christene

  4. Apartheid et Israël-Palestine : enseignements et contresens d’une analogie

    2004-11-01

    Full Text Available L’analogie entre l’apartheid et la situation en Israël-Palestine envahit les commentaires et les analyses. Elle prend cependant différentes formes. L’usage radical et systématique de l’analogie vise à condamner l’Etat d’Israël et le sionisme dans leur nature même. Cette approche infondée est aisément réfutable par l’analyse comparée des deux systèmes politiques et sociaux, y compris la discrimination des Arabes israéliens par rapport à celle des non Blancs en Afrique du Sud de l’apartheid. L’usage conjoncturel à visée critique ou constructive de l’analogie s’applique quant à elle exclusivement au traitement des Territoires occupés par Israël et fait référence à la politique du « grand apartheid » et ses bantoustans. Bien que s’appuyant sur quelques éléments communs, cet usage de l’analogie ne résiste pas à une analyse technique et contextualisée des ingénieries territoriales et politiques. Là où le « grand apartheid » relevait d’un système politico-territorial profondément raciste mais de nature postcoloniale, la politique israélienne vis-à-vis des Territoires occupés et plus généralement le sionisme contemporain, apparaissent comme un nationalisme de pratique coloniale, au sens étroit du terme (primat de l’appropriation foncière et de l’annexion sur les autres formes de domination. Les perspectives de résolution du conflit font également l’objet d’approches comparatives qui s’intéressent à l’expérience sud-africaine. Là aussi l’analogie entre les deux situations offre peu de points communs sur lesquels s’appuyer pour concevoir les modalités d’un compromis géopolitique et d’une réconciliation. En revanche, le rapport renouvelé au territoire et à la souveraineté, esquissé à Genève, relève d’un post-sionisme territorial qui semble porteur de solutions.

  5. Ammonia recovery from anaerobically digested cattle manure by steam stripping.

    2006-01-01

    Ammonia recovery from anaerobically digested cattle manure effluents through steam stripping was studied at a stripping tower temperature of 98-99 degrees C and a steam-water ratio approximately 56-72 g/L. The digested manure effluents were first treated by microfiltration and then the permeate was used as feed in steam stripping. The stripping performance was evaluated under different feed pH values, ammonia concentrations and temperatures. The increase of the initial feed pH does not significantly improve ammonia stripping efficiency due to the fact that the stripped effluent pH is increased during steam stripping. This suggests that steam stripping of anaerobically digested manure effluents for ammonia recovery may not need pre-raised pH. In contrast, the pH value of the synthetic ammonia wastewater containing NH4Cl dramatically decreases after steam stripping. Increasing the feed temperature slightly improves ammonia stripping efficiency, but reduces the concentration of the recovered ammonia in the condensate due to an increased condensate volume at a higher feed temperature. Therefore, the feed temperature should be controlled at an optimum point that can compromise the condensate ammonia concentration and the ammonia stripping efficiency. Experimental results indicate that recovery of ammonia from anaerobically digested cattle manure effluents as NH4OH is technically feasible.

    This paper describes a dual beam thruster that has been designed, constructed, and tested. The system is suitable for two-axes attitude control and is comprised of two orthogonal strips, each capable of producing 0.30 mlb thrust and beam deflections of more than plus or minus 20 deg. The nominal specific impulse for the thruster is 5000 sec, and the thrust level from each strip can be varied from 0 to 100%. Neutralizer filaments that were developed and life tested over 2000 hours producing more than 40 mA of electron emission per watt of input power are also discussed. The system power required for clean ionizers is approximately 200 W.

  7. Nuclear reactor spring strip grid spacer

    Patterson, J.F.; Flora, B.S.

    1980-01-01

    An improved and novel grid spacer was developed for use in nuclear reactor fuel assemblies. It is comprised of a series of intersecting support strips and a peripheral support band attached to the ends of the support strips. Each of the openings into which the fuel element is inserted has a number of protruding dimples and springs extending in different directions. The dimples coact with the springs to secure the fuel rods in the openings. Compared with previous designs, this design gives more positive alignment of the support stips while allowing greater flexibility to counterbalance the effects of thermal expansion. The springs are arranged in alternating directions so that the reaction forces tend to counterbalance each other, which in turn minimizes the reaction loads on the supporting structure. (D.N.)

    Full Text Available In this article, the analysis of dualband L-strip fed compact semi-circular disk microstrip patch antenna has been presented using circuit theory concept. The antenna parameters such as return loss, VSWR and radiation pattern are calculated. The effect of geometric dimensions of the proposed antenna such as length of vertical and horizontal portion of L-strip is investigated. It is found that antenna resonate at two distinct modes i.e. 1.3 GHz and 6.13 GHz for lower and upper resonance frequencies respectively. The bandwidth of the proposed antenna at lower resonance frequency is 6.61% (simulated and 10.64% (theoretical whereas at upper resonance frequency, it is 6.02% (simulated and 9.06 % (theoretical. The theoretical results are compared with IE3D simulation results as well as experimental results and they are in close agreement.

    Full Text Available Strip-till save costs by reducing tillage on the area of sugar beet rows only. The seeding system is characterized by a deep loosening of soil with a tine combined with a share and by following tools generating fine-grained soil as seed bed. In cooperation with the Kverneland company group Soest/Germany a strip tiller combined with precision seeder was designed and tested in field experiments. Tilling and seeding was performed in one path on fields with straw and mustard mulch. Even the plant development was slower as compared to conventional sawn sugar beets the yield was on equivalent level. Further field experiments are planned to attest constant yield, cost and energy efficiency of the seeding system.

    Many of the technical problems of generating a large thin liquid sheet from 0.02 to 0.20 μm thick (3 to 40 μgm/cm 2 ) have been solved. It is shown that this perennial sheet is stable and consonant in dimension. Several ion beam species from the SuperHILAC have been used for evaluation; at 0.11 MeV/n. In one of three modes this sheet serves as an equivalent substitute for a carbon foil. The second mode is characterized by a solid-like charge state distribution but with a varying fraction of unstripped ions. The third mode gives stripping performance akin to a vapor stripping medium. 9 references, 7 figures

    Limitation of bridge's carrying bearing capacity due to aging and deterioration is a common problem faced by road administration and drivers. Rehabilitation of bridges including strengthening may be applied in order to maintain or upgrade existing bridge parameters. The case studies of strengthening of two small bridges with high modulus prestressed CFRP strips have been presented in the paper. The first one - reinforced concrete slab bridge - and the other - composite steel-concrete girder bridge - have been successfully upgraded with quite new technology. In both cases the additional CFRP reinforcement let increasing of bridge carrying capacity from 15 till 40 metric tons. The CFRP strip prestressing system named Neoxe Prestressing System (NPS), developed by multi-disciplinary team and tested at full scale in Rzeszow University of Technology, has been also described in the paper.

    Many supersymmetric models such as the constrained minimal supersymmetric extension of the Standard Model (CMSSM) feature a strip in parameter space where the lightest neutralino χ is identified as the lightest supersymmetric particle, the lighter stop squark t{sub 1} is the next-to-lightest supersymmetric particle (NLSP), and the relic χ cold darkmatter density is brought into the range allowed by astrophysics and cosmology by coannihilation with the lighter stop squark t{sub 1} NLSP. We calculate the stop coannihilation strip in the CMSSM, incorporating Sommerfeld enhancement effects, and we explore the relevant phenomenological constraints and phenomenological signatures. In particular, we show that the t{sub 1} may weigh several TeV, and its lifetime may be in the nanosecond range, features that are more general than the specific CMSSM scenarios that we study in this paper.

    An antenna comprises electrical conductors arranged to form a radiating element including a folded line configuration and a distributed strip configuration, where the radiating element can be in proximity to a ground conductor and/or arranged as a dipole. Embodiments of the antenna include conductor patterns formed on a printed wiring board, having a ground plane, spacedly adjacent to and coplanar with the radiating element. An antenna can comprise a distributed strip patterned on a printed wiring board, integrated with electronic components mounted on top of or below the distributed strip, and substantially within the extents of the distributed strip. Mounting of electronic components on top of or below the distributed strip has little effect on the performance of the antenna, and allows for realizing the combination of the antenna and integrated components in a compact form. An embodiment of the invention comprises an antenna including a distributed strip, integrated with a battery mounted on the distributed strip.

    The stability of H - beams passing through strong magnetic fields has been relevant to accelerator transport problems and, recently, to neutral beam preparation techniques. The H - electron detachment rate was measured as a function of rest-frame electric field and provides parameters for a theoretical lifetime expression. The limitations imposed on H - transport by magnetic stripping, and neutral-beam preparation in emittance growth, magnetic fields, and beam energies are discussed. Application techniques are also briefly discussed

    Full Text Available Cystic fibrosis (CF is an autosomal recessive inherited life-threatening disorder that causes severe damage to the lungs and the digestive system. In Palestine, mutations in the Cystic Fibrosis Transmembrane Conductance Regulator gene (CFTR that contributes to the clinical presentation of CF are ill defined. A cohort of thirty three clinically diagnosed CF patients from twenty one different Palestinian families residing in the central and southern part of Palestine were incorporated in this study. Sweat chloride testing was performed using the Sweat Chek Conductivity Analyzer (ELITECH Group, France to confirm the clinical diagnosis of CF. In addition, nucleic acid from the patients' blood samples was extracted and the CFTR mutation profiles were assessed by direct sequencing of the CFTR 27 exons and the intron-exon boundaries. For patient's DNA samples where no homozygous or two heterozygous CFTR mutations were identified by exon sequencing, DNA samples were tested for deletions or duplications using SALSA MLPA probemix P091-D1 CFTR assay. Sweat chloride testing confirmed the clinical diagnosis of CF in those patients. All patients had NaCl conductivity >60 mmol/l. In addition, nine different CFTR mutations were identified in all 21 different families evaluated. These mutations were c.1393-1G>A, F508del, W1282X, G85E, c.313delA, N1303K, deletion exons 17a-17b-18, deletion exons 17a-17b and Q1100P. c.1393-1G>A was shown to be the most frequent occurring mutation among tested families. We have profiled the underling mutations in the CFTR gene of a cohort of 21 different families affected by CF. Unlike other studies from the Arab countries where F508del was reported to be the most common mutation, in southern/central Palestine, the c.1393-1G>A appeared to be the most common. Further studies are needed per sample size and geographic distribution to account for other possible CFTR genetic alterations and their frequencies. Genotype

    Evidence is conflicting as to the whether tobacco smoking prevalence is higher in refugee than non-refugee populations. The aim of this study was to compare the prevalence and frequency of tobacco smoking in Palestine refugee and non-refugee adolescent populations in the Middle East. We conducted a cross-sectional analysis of the Global Youth Tobacco Survey (GYTS) conducted in Jordan, Lebanon, Syria, and the West Bank among adolescent Palestine refugees and non-refugees. Age- and sex-adjusted regression models assessed the association between refugee status and current (past-30 day) tobacco use prevalence and frequency. Prevalence estimates for current tobacco smoking were similar between Palestine refugee and non-refugee groups in Jordan (26.7 % vs. 24.0 %), Lebanon (39.4 % vs. 38.5 %), and the West Bank (39.5 % vs. 38.4 %). In Syria, Palestine refugees had nearly twice the odds of current tobacco smoking compared to non-refugees (23.2 % vs. 36.6 %, AOR 1.96, 95 % CI 1.46-2.62). Palestine refugees consumed more cigarettes per month than non-refugees in Lebanon (β 0.57, 95 % CI 0.17-0.97) and Palestine refugees consumed more waterpipe tobacco per month than non-refugees in Syria (β 0.40, 95 % CI 0.19-0.61) and the West Bank (β 0.42, 95 % CI 0.21-0.64). Current tobacco smoking prevalence is in excess of 20 % in both adolescent Palestine refugee and non-refugee populations in Middle Eastern countries, however Palestine refugees may smoke tobacco more frequently than non-refugees. Comparison of simple prevalence estimates may therefore mask important differences in tobacco use patterns within population groups.

  1. CLOSED-LOOP STRIPPING ANALYSIS (CLSA) OF ...

    Science.gov (United States)

    Synthetic musk compounds have been found in surface water, fish tissues, and human breast milk. Current techniques for separating these compounds from fish tissues require tedious sample clean-upprocedures A simple method for the deterrnination of these compounds in fish tissues has been developed. Closed-loop stripping of saponified fish tissues in a I -L Wheaton purge-and-trap vessel is used to strip compounds with high vapor pressures such as synthetic musks from the matrix onto a solid sorbent (Abselut Nexus). This technique is useful for screening biological tissues that contain lipids for musk compounds. Analytes are desorbed from the sorbent trap sequentially with polar and nonpolar solvents, concentrated, and directly analyzed by high resolution gas chromatography coupled to a mass spectrometer operating in the selected ion monitoring mode. In this paper, we analyzed two homogenized samples of whole fish tissues with spiked synthetic musk compounds using closed-loop stripping analysis (CLSA) and pressurized liquid extraction (PLE). The analytes were not recovered quantitatively but the extraction yield was sufficiently reproducible for at least semi-quantitative purposes (screening). The method was less expensive to implement and required significantly less sample preparation than the PLE technique. The research focused on in the subtasks is the development and application of state-of the-art technologies to meet the needs of the public, Office of Water,

  2. Deuteron stripping reactions with Tabakin potential

    1976-05-01

    Deuteron stripping reactions are considered. Due to the strong repulsion between nucleons at very short distances, we have investigated the nuclear short-range correlations. The neutron proton nuclear potential in the deuteron is taken as a short-range repulsive core surrounded by a long-range attractive potential. The neutron-proton potential is taken as the Tabakin separable potential to take into account the short-range correlations. The differential cross-sections for deuteron stripping reactions have been calculated in two different cases by taking Yamaguchi or Breit et al type parameters for the Tabakin potential used. The angular distributions for different (d,p) stripping reactions on the different target nuclei 28 Si, 32 , 34 S, 36 Ar, 40 , 48 Ca, 50 , 52 , 54 Cr have been calculated using the DWBA calculations. Our present theoretical calculations for the angular distributions of the different reactions cosidered have been fitted to the experimental data, where good agreement is obtained. The extracted spectroscopic factors from the present work are found to be more reliable

    The module is made out of four 6 cm x 6 cm single sided Si microstrip detectors. Two detectors are butt glued to form a 12 cm long mechanical unit and strips of the two detectors are electrically connected to form 12 cm long strips. The butt gluing is followed by a back to back attachment. The module in this note is the Rφ module where the electronics is oriented parallel to the strip direction and bonded directly to the strips. This module concept provides the maximum signal-to-noise ratio, particularly when the front-end electronics is placed near the middle rather than at the end. From the noise analysis, it is concluded that the worst-case ΔENC (far-end injection) between end- and center-tapped modules will be 120 to 210 el. rms (9 to 15%) for a non-irradiated detector and 75 to 130 el. rms (5 to 9%) for an irradiated detector, for a metal strip resistance of 10 to 20 Ω/cm

    In six United Nations Relief and Works Agency (UNRWA) primary health care clinics in Jordan serving Palestine refugees diagnosed with hypertension, to determine the number, characteristics, programme outcomes and measures of disease control for those registered up to 30 June, 2013, and in those who attended clinic in the second quarter of 2013, the prevalence of disease-related complications between those with hypertension only and hypertension combined with diabetes mellitus. Retrospective cohort study with programme and outcome data collected and analysed using E-Health. There were 18 881 patients registered with hypertension with females (64%) and persons aged ≥ 40 years (87%) predominating. At baseline, cigarette smoking was recorded in 17%, physical inactivity in 48% and obesity in 71% of patients. 77% of all registered patients attended clinic in the second quarter of 2013; of these, 50% had hypertension and diabetes and 50% had hypertension alone; 9% did not attend the clinics and 10% were lost to follow-up. Amongst those attending clinic, 92% had their blood pressure measured, of whom 83% had blood pressure <140/90 mm Hg. There were significantly more patients with hypertension and diabetes (N = 966, 13%) who had disease-related complications than patients who had hypertension alone (N = 472, 6%) [OR 2.2, 95% CI 2.0-2.5], and these differences were found for both males [18% vs. 10%, OR 1.9, 95% CI 1.6-2.2] and females [11% vs. 5%, OR 2.4, 95% CI 2.1-2.9]. Large numbers of Palestine refugees are being registered and treated for hypertension in UNRWA primary health care clinics in Jordan. Cohort analysis and E-Health can be used to regularly assess caseload, programme outcomes, clinic performance, blood pressure control and cumulative prevalence of disease-related complications. Current challenges include the need to increase clinic attendance and attain better control of blood pressure. © 2014 John Wiley & Sons Ltd.

    This study aimed at isolation of phenol degrading bacteria from olive mill wastes in Palestine. The efficiency of phenol removal and factors affecting phenol degradation were investigated. A bacterial strain (J20) was isolated from solid olive mill waste and identified as Bacillus thuringiensis based on standard morphological, biochemical characteristics and 16SrRNA sequence analysis. The strain was able to grow in a phenol concentration of 700 mg/L as the sole carbon and energy source. The culture conditions showed a significant impact on the ability of these cells to remove phenol. This strain exhibited optimum phenol degradation performance at pH 6.57 and 30 °C . Under the optimized conditions, this strain could degrade 88.6% of phenol (700 mg/L) within 96 h when the initial cell density was OD 600 0.2. However, the degradation efficiency could be improved from about 88% to nearly 99% by increasing the cell density. Immobilization of J20 was carried out using 4% sodium alginate. Phenol degradation efficiency of the immobilized cells of J20 was higher than that of the free cells, 100% versus 88.6% of 700 mg/L of phenol in 120 h, indicating the improved tolerance of the immobilized cells toward phenol toxicity. The J20 was used in detoxifying crude OMWW, phenolic compounds levels were reduced by 61% compared to untreated OMWW after five days of treatment. Hence, B. thuringiensis-J20 can be effectively used for bioremediation of phenol-contaminated sites in Palestine. These findings may lead to new biotechnological applications for the degradation of phenol, related to olive oil production.

    This is the first study to investigate how actively engaged and vigorous people remain in their life tasks in the midst of chronic exposure to significant traumatic events. We sought to identify risk and protective factors for engagement within the context of ongoing exposure to political violence and social upheaval. We randomly identified and interviewed 1,196 adult residents of the West Bank and Gaza during a period of violent conflict on 3 occasions: (1) September-October 2007, (2) April-May 2008, and (3) October-November 2008. Participants were asked about their exposure to political violence, symptoms of depression, and posttraumatic stress (PTS) symptoms, their level of social support, psychosocial resource loss, and positive engagement in life tasks. Path modeling revealed that trauma exposure indirectly affected engagement through its impact on resource loss and PTS and depression symptoms. PTS symptoms at Wave 2 were modestly related to greater engagement at Wave 3, and depression symptoms did not independently predict engagement at Wave 3. Psychosocial resource loss at Wave 1 and Wave 2 was the best overall predictor of engagement at Wave 3, through its direct and indirect effects via PTS symptoms. Greater engagement was also predicted by greater social support, being more educated, being younger, and being more religious. The relative independence of psychological distress and engagement was noted as a critical finding supporting a key tenet of positive psychology. The relationship of resource loss and social support with engagement suggests that bolstering psychosocial resources may offer a route for primary and secondary prevention amidst chronic traumatic conditions. © 2012 Guilford Publications, Inc.

    High pressure water cutting techniques have a wide range of applications to the American space effort. Hydroblasting techniques are commonly used during the refurbishment of the reusable solid rocket motors. The process can be controlled to strip a thermal protective ablator without incurring any damage to the painted surface underneath by using a variation of possible parameters. Hydroblasting is a technique which is easily automated. Automation removes personnel from the hostile environment of the high pressure water. Computer controlled robots can perform the same task in a fraction of the time that would be required by manual operation.

    The Compact Muon Solenoid (CMS) experiment at LHC features the largest Silicon Strip Tracker (SST) ever build. This device is immersed in a 4T magnetic field and, in conjunction with a Pixel system, it allows the momentum of the charged particles to be measured and the heavy-flavour final states to be tagged despite the hostile radiation environment. The impact of operating conditions and physics requirements on the SST layout and design choices is discussed and the expected performances are reviewed. The SST collaboration is now facing the production of the ~15000 modules and their assembly into the SST substructures. A status is given.

    Heung, L.K.; Gibson, G.W.; Ortman, M.S.

    1991-01-01

    A catalytic exchange process for stripping elemental tritium from gas streams has been demonstrated. The process uses a catalyzed isotopic exchange reaction between tritium in the gas phase and protium or deuterium in the solid phase on alumina. The reaction is catalyzed by platinum deposited on the alumina. The process has been tested with both tritium and deuterium. Decontamination factors (ration of inlet and outlet tritium concentrations) as high as 1000 have been achieved, depending on inlet concentration. The test results and some demonstrated applications are presented

    2005-01-01

    Strip extensometry tests are usually considered less reliable than trephinate inflation tests in studying corneal biomechanics. In spite of the evident simplicity of strip extensometry tests, several earlier studies preferred inflation tests in determining the constitutive relationship of the cornea and its other material properties, such as Young's modulus and the hysteresis behaviour. In this research, the deficiencies of the strip tests are discussed and a mathematical procedure presented ...

    Full Text Available Deformation strips have been experimentally revealed and described while stretching of cylindrical samples by means of computer thermography. It has been established that temperature of shift strip surface grows smoothly up to the stage of crack origin in material defect. Sharp growth of surface temperature occurs when tensile stresses reach tensile strength. Change in surface temperature occurs wavy after destruction (while cooling the sample. Processes of material destruction origin and development  characterize temperature changes in deformation strips.

  15. 'Irish & Roman Catholic Which Upsets All the People Here': Michael McDonnell and British Colonial Justice in Mandatory Palestine, 1927-1936.

    Science.gov (United States)

    Davis, Simon

    2017-10-23

    In 1927 Michael McDonnell, a diasporic Irish Catholic, was appointed Mandatory Palestine's Chief Justice, being directed to institute firm British-style legal-judicial foundations for future self-governance. This entailed common, equal status for Arab and Jewish Palestinians, implicitly de-privileging the Jewish National Home. McDonnell was resisted in this by the British Mandate's Anglo-Jewish, pro-Zionist Attorney General, Norman Bentwich. McDonnell prevailed but only at the cost of being characterized lastingly as a pro-Arab, Catholic anti-Semite. McDonnell's continuing defence of a supreme, independent judiciary antagonized the Palestine Executive of High Commissioner Arthur Wauchope, who tried to co-opt rather than subordinate Zionist interests. Consequent frictions culminated in 1936 with McDonnell adjudicating against supra-legal British repression of Palestine's great Arab rebellion. For this he was dismissed and ostracized, subsequently publishing critiques of British policy in fringe right-wing organs. Yet McDonnell professed explicitly non-racist views, reflecting a liberal-minded, constitutional Irish nationalist equation of Palestine with Ireland, seeing comparable settler-colonial abuses and native distress as remediable only by transcendentally impartial justice. Britain reneging on these principles led McDonnell, like those Irish imperial servants noted in India, to identify with colonial subjects against colonialism. His case is one of empire as a system of domination being challenged from within, although his removal foreshadowed emerging imperial counter-insurgency's tendency not only to repress subject populations but deny civil-progressive alternatives for managing post-colonial transition. © The Author [2017].

  16. Stability of barotropic vortex strip on a rotating sphere.

    Sohn, Sung-Ik; Sakajo, Takashi; Kim, Sun-Chul

    2018-02-01

    We study the stability of a barotropic vortex strip on a rotating sphere, as a simple model of jet streams. The flow is approximated by a piecewise-continuous vorticity distribution by zonal bands of uniform vorticity. The linear stability analysis shows that the vortex strip becomes stable as the strip widens or the rotation speed increases. When the vorticity constants in the upper and the lower regions of the vortex strip have the same positive value, the inner flow region of the vortex strip becomes the most unstable. However, when the upper and the lower vorticity constants in the polar regions have different signs, a complex pattern of instability is found, depending on the wavenumber of perturbations, and interestingly, a boundary far away from the vortex strip can be unstable. We also compute the nonlinear evolution of the vortex strip on the rotating sphere and compare with the linear stability analysis. When the width of the vortex strip is small, we observe a good agreement in the growth rate of perturbation at an early time, and the eigenvector corresponding to the unstable eigenvalue coincides with the most unstable part of the flow. We demonstrate that a large structure of rolling-up vortex cores appears in the vortex strip after a long-time evolution. Furthermore, the geophysical relevance of the model to jet streams of Jupiter, Saturn and Earth is examined.

    An improved strip detector and a method for making such a detector in which a high resistivity N conduction semiconductor body has electrode strips formed thereon by diffusion is described. The strips are formed so as to be covered by an oxide layer at the surface point of the PN junction and in which the opposite side of the semiconductor body then has a substantial amount of material etched away to form a thin semiconductor upon which strip electrodes which are perpendicular to the electrodes on the first side are then placed

  18. Strip defect recognition in electrical tests of silicon microstrip sensors

    Energy Technology Data Exchange (ETDEWEB)

    Valentan, Manfred, E-mail: valentan@mpp.mpg.de

    2017-02-11

    This contribution describes the measurement procedure and data analysis of AC-coupled double-sided silicon microstrip sensors with polysilicon resistor biasing. The most thorough test of a strip sensor is an electrical measurement of all strips of the sensor; the measured observables include e.g. the strip's current and the coupling capacitance. These measurements are performed to find defective strips, e.g. broken capacitors (pinholes) or implant shorts between two adjacent strips. When a strip has a defect, its observables will show a deviation from the “typical value”. To recognize and quantify certain defects, it is necessary to determine these typical values, i.e. the values the observables would have without the defect. As a novel approach, local least-median-of-squares linear fits are applied to determine these “would-be” values of the observables. A least-median-of-squares fit is robust against outliers, i.e. it ignores the observable values of defective strips. Knowing the typical values allows to recognize, distinguish and quantify a whole range of strip defects. This contribution explains how the various defects appear in the data and in which order the defects can be recognized. The method has been used to find strip defects on 30 double-sided trapezoidal microstrip sensors for the Belle II Silicon Vertex Detector, which have been measured at the Institute of High Energy Physics, Vienna (Austria).

    2004-12-01

    Full Text Available Pavement weathering or stripping is a major distress in highway networks in arid regions. Using the Saudi Arabian road network as a case study area, seventeen road test sections were selected, out of which eight were stripped and nine were non-stripped. Aggregates from quarries used to build these sections were also collected and subjected to detailed physical and chemical tests to evaluate the ability of these tests to distinguish between stripped and non-stripped sections. The modified Lottman test was used to distinguish between compacted mixes. In addition, the Swedish Rolling Bottle test, was also found to be effective in being able to distinguish between different asphalt-aggregates for stripping potential. Eleven anti-stripping liquid additives, lime and cement, in addition to two polymers, were evaluated for their ability to reduce/eliminate stripping potential of stripping-prone aggregates. It was found that EE-2 Polymer, Portland cement, and their combination were effective with all aggregate sources.

    Full Text Available BackgroundDespite the huge numbers of the internationally produced and implemented Clinical Practice Guidelines (CPGs, the compliance with them is still low in health care. This study aimed at assessing the attitudes of Palestinian health-care professionals toward the most perceived factors influencing the adherence to the CPG for Diabetes Mellitus in the Primary Health-care centers of the Ministry of Health (PHC-MoH and the Primary Health-care centers of the United Nations Relief and Works Agency for Palestine Refugees (PHC-UNRWA using a validated questionnaire.MethodsA cross-sectional design was employed with a census sample of all Palestinian family doctors and nurses (n = 323. The Cabana theoretical framework was used to develop a study questionnaire. A cross cultural adaptation framework was followed to develop the Arabic version questionnaire. The psychometric properties of Arabic version were finally assessed.ResultsThe Arabic version questionnaire showed a good construct validity and internal consistency reliability. The overall adherence level to the diabetic guideline was disappointingly suboptimal 51.5% (47.3% in the PHC-MoH and 55.5% in the PHC-UNRWA P = 0.000. The most frequently perceived barriers in the PHC-MoH were lack of incentives, lack of resources, and lack of guideline trustworthiness, whereas the lack of time and the lack of guideline trustworthiness were the most prominent barriers in the PHC-UNRWA. In spite of the lack of trustworthiness of the diabetic guideline, most respondents in both settings had a positive attitude toward guidelines in general, but this attitude was not a predictor of guideline adherence.ConclusionThe good validity and reliability of our questionnaire can provide support for the accuracy of our findings. Multifaceted implementation strategies targeting the main barriers elicited from this study are required for addressing the lack of incentives, organizational resources, lack of confidence

    2007-12-01

    We measured villous cell intracellular pH (pH(i)) and solute diffusion between the bathing media and the epithelial cells in stripped, chambered mouse duodenum. Apical perfusion of a high CO2 solution rapidly acidified the upper villous cells with recovery after its removal. Apical zoniporide (ZP) enhanced CO(2)-induced acidification. Serosal ZP, dimethylamiloride (DMA) or stilbene anion transport inhibitors failed to alter CO(2)-induced acidification, whereas serosal high CO(2) buffer acidified the upper villous cells. Serosal 5-hydroxytryptamine rapidly acidified the upper villous cells. All serosally-perfused fluorescent compounds stained the crypt area, but not the villi or villous cells. In contrast, intravenous carboxyfluorescein quickly diffused into the interstitial space of the entire mucosa, and mucosally perfused fluorescent compound rapidly penetrated the epithelial cell layer. In muscle-stripped duodenum mounted in a small-aperture perfusion chamber, serosal solutes can readily diffuse only to the crypt cell region, whereas access to the villous epithelial cells is diffusion-limited. In contrast, rapid villous cell responses to serosally applied solutes are best explained by neural reflexes. Limited viability of the villous cells and impaired structural stability of the villi further limit long-term, villous cell functional studies of mucosal preparations mounted in small aperture diffusion chambers.

    Throughout history, every civilization in the world used plants or their derivatives for treatment or prevention of diseases. In Palestine as in many other countries, herbal medicines are broadly used in the treatment of wide range of diseases including urological diseases. The main objective of this research is to study the use of herbal remedies by herbalists and traditional healers for treatment of various urological diseases in the West Bank regions of Palestine and to assess their efficacy and safety through the literature review of the most cited plants. The study included a survey part, plant identification and a review study. The first part was a cross-sectional descriptive study. Face to face questionnaires were distributed to 150 traditional healers and herbalist in all regions of the West Bank of Palestine. The literature review part was to assess the most cited plants for their efficacy and toxicity. One hundred forty four herbalists and traditional healers accepted to participate in this study which was conducted between March and April, 2016. The results showed that 57 plant species belonging to 30 families were used by herbalists and traditional healers for treatment of various urinary tract diseases in Palestine. Of these, Apiaceae family was the most prevalent. Paronychia argentea, Plantago ovata, Punica granatum, Taraxacum syriacum, Morus alba and Foeniculum vulgare were the most commonly used plant species in the treatment of kidney stones, while Capsella bursa-pastoris, Ammi visnaga and Ammi majus were the most recommended species for treatment of urinary tract infections and Portulaca oleracea used for renal failure. In addition Curcuma longa and Crocus sativus were used for enuresis while Juglans regia, Quercus infectoria, Sambucus ebulus and Zea mays were used for treatment symptoms of benign prostate hyperplasia. Fruits were the most common parts used, and a decoction was the most commonly used method of preparation. Through literature

    The maternal near-miss approach has been increasingly used as a tool to evaluate and improve the quality of care in maternal health. We report findings from the formative stage of a World Health Organization (WHO) funded implementation research study that was undertaken to collect primary data at the facility level on the prevalence, characteristics, and management of maternal near-miss cases in four major public referral hospitals - one each in Egypt, Lebanon, Palestine and Syria. We conducted a cross sectional study of maternal near-miss cases in the four contexts beginning in 2011, where we collected data on severe maternal morbidity in the four study hospitals, using the WHO form (Individual Form HRP A65661). In each hospital, a research team including trained hospital healthcare providers carried out the data collection. A total of 9,063 live birth deliveries were reported during the data collection period across the four settings, with a total of 77 cases of severe maternal outcomes (71 maternal near-miss cases and 6 maternal deaths). Higher indices for the maternal mortality index were found in both Al Galaa hospital, in Egypt (8.6%) and Dar Al Tawleed hospital in Syria (14.3%), being large referral hospitals, compared to Ramallah hospital in Palestine and Rafik Hariri University hospital in Lebanon. Compared to the WHO's Multicountry Survey using the same data collection tool, our study's mortality indices are higher than the index of 5.6% among countries with a moderate maternal mortality ratio in the WHO Survey. Overall, haemorrhage-related complications were the most frequent conditions among maternal near-miss cases across the four study hospitals. In all hospitals, coagulation dysfunctions (76.1%) were the most prevalent dysfunction among maternal near-miss cases, followed by cardiovascular dysfunctions. The coverage of key evidence-based interventions among women experiencing a near-miss was either universal or very high in the study hospitals

    Medication dosing errors are a significant global concern and can cause serious medical consequences for patients. Pediatric patients are at increased risk of dosing errors due to differences in medication pharmacodynamics and pharmacokinetics. The aims of this study were to find the rate of medication dosing errors in hospitalized pediatric patients and possible associated factors. The study was an observational cohort study including pediatric inpatients less than 16 years from three governmental hospitals from the West Bank/Palestine during one month in 2014, and sample size was 400 pediatric inpatients from these three hospitals. Pediatric patients' medical records were reviewed. Patients' weight, age, medical conditions, all prescribed medications, their doses and frequency were documented. Then the doses of medications were evaluated. Among 400 patients, the medications prescribed were 949 medications, 213 of them (22.4%) were out of the recommended range, and 160 patients (40.0%) were prescribed one or more potentially inappropriate doses. The most common cause of hospital admission was sepsis which presented 14.3% of cases, followed by fever (13.5%) and meningitis (10.0%). The most commonly used medications were ampicillin in 194 cases (20.4%), ceftriaxone in 182 cases (19.2%), and cefotaxime in 144 cases (12.0%). No significant association was found between potentially inappropriate doses and gender or hospital (chi-square test p -value > 0.05).The results showed that patients with lower body weight, who had a higher number of medications and stayed in hospital for a longer time, were more likely to have inappropriate doses. Potential medication dosing errors were high among pediatric hospitalized patients in Palestine. Younger patients, patients with lower body weight, who were prescribed higher number of medications and stayed in hospital for a longer time were more likely to have inappropriate doses, so these populations require special care.

    1995-01-01

    An elongated fixture handle member is connected to a fixture body member with both members having interconnecting longitudinal central axial bores for the passage of an optical cable therethrough. The axial bore of the fixture body member, however, terminates in a shoulder stop for the outer end of a jacket of the optical cable covering both an optical fiber and a coating therefor, with an axial bore of reduced diameter continuing from the shoulder stop forward for a predetermined desired length to the outer end of the fixture body member. A subsequent insertion of the fixture body member including the above optical fiber elements into a chemical stripping solution results in a softening of the exposed external coating thereat which permits easy removal thereof from the optical fiber while leaving a desired length coated fiber intact within the fixture body member.

    2011-01-01

    The Large Hadron Collider at CERN will extend its current physics program by increasing the peak luminosity by one order of magnitude. For ATLAS, one of the two general-purpose experiments of the LHC, an upgrade scenario will imply the complete replacement of its internal tracker due to the harsh conditions in terms of particle rates and radiation doses. New radiation-hard prototype n-in-p silicon sensors have been produced for the short-strip region of the future ATLAS tracker.

    1995-04-01

    Dynamic Underground Stripping (DUS) is a combination of technologies targeted to remediate soil and ground water contaminated with organic compounds. DUS is effective both above and below the water table and is especially well suited for sites with interbedded sand and clay layers. The main technologies comprising DUS are steam injection at the periphery of a contaminated area to heat permeable subsurface areas, vaporize volatile compounds bound to the soil, and drive contaminants to centrally located vacuum extraction wells; electrical heating of less permeable sediments to vaporize contaminants and drive them into the steam zone; and underground imaging such as Electrical Resistance Tomography to delineate heated areas to ensure total cleanup and process control. A full-scale demonstration was conducted on a gasoline spill site at Lawrence Livermore National Laboratory in Livermore, California from November 1992 through December 1993

    Strip extensometry tests are usually considered less reliable than trephinate inflation tests in studying corneal biomechanics. In spite of the evident simplicity of strip extensometry tests, several earlier studies preferred inflation tests in determining the constitutive relationship of the cornea and its other material properties, such as Young's modulus and the hysteresis behaviour. In this research, the deficiencies of the strip tests are discussed and a mathematical procedure presented to take account of these deficiencies when obtaining the corneal material properties. The study also involves testing 10 pairs of porcine corneas using both strip extensometry and trephinate inflation techniques and the results are subjected to mathematical back analysis in order to determine the stress-strain behaviour. The behaviour obtained from the strip extensometry tests and using the new mathematical analysis procedure is shown to match closely the inflation test results.

    The feasibility of using of current-biased superconducting strips for radiation detection is investigated. Narrow Ta strips are exposed to 5.5 MeV [alpha]-particle radiation and the rise-time of the induced voltage pulses is measured as function of temperature and bias current. The rise-time of the voltage signal strongly depends on the site on the strip which is hit by the [alpha]-particle. In order to determine the spatial resolution of a superconducting strip detector, position-sensitive measurements were performed. The maximum lateral resolution estimated so far is 25[mu]m in a 7[mu]m wide, 340 nm thick and 0.6 mm long Ta-strip. (orig.)

    Full Text Available This paper focuses on the voltammetric determination of lead, cadmium and zinc in water. Two ways of determining were investigated: individually and all three metals simultaneously. The experiments were performed using the Potentiometric Stripping Analysis (PSA. Determination of metals in real samples was preceded by preliminary tests. Preliminary investigations were performed in order to determine the optimal conditions of measurement. It was concluded that the process of determining was for most part influenced by: pH, time of metals extraction, stirring rate of the solution and the thickness of the mercury layer on the working electrode. The smallest concentrations of metals which can be determined using this method are: for lead 22.48 μg dm-3, for cadmium 16.23 μg dm-3 and for zinc 18.75 μg dm-3. The obtained results deviated from the actual 1.12% for lead, 1.91% for cadmium and 1.81% for zinc. All tests (individually and simultaneously were conducted from model solution with concentration as follows: 44.96 μg dm-3 for lead, 32.47 μg dm-3 for cadmium and 37.50 μg dm-3 for zinc. The results of individual measurements deviated by 1.02% lead, 1.90% for cadmium and 1.89% for zinc. Simultaneously the contents were lower than real for: -4.58% for lead, cadmium for -1.91% and -1.89% for zinc. For the conditions determined, except for lead, deviations did not exceed ±2% . This indicates that Potentiometric Stripping Analysis is a good way of individual and simultaneous determination of lead, cadmium and zinc and for determination of their concentrations in water (river and groundwater.

    Coupons with the same composition and thickness (4.0 mm nominal gauge) obtained from hot strips of low carbon steel underwent a series of investigations to analyze the microstructural characteristics and mechanisms responsible for their differences in mechanical properties. Two different industrial technologies were adopted, although the strips used in this research were produced on the same Compact Strip Production (CSP) line. One of the strips was produced with a routine γ→α CSP thermal history, but the other with a γ→α→γ* conventional thermal history. The only difference between them was that one technology had a α→γ* thermal history. Different specimens of both types of strips were prepared for metallographic observation, tensile tests, electron back-scattered diffraction tests and positron annihilation technique tests. Experimental results showed that the differences in mechanical properties could be ascribed to dissimilarities not only in the grain size and textural components but also in dislocation density

The development of technology to improve soil quality in marginal lands to be productive lands is still widely open for agricultural development in Indonesia. Rooting medium quality can be improved by changing soil tillage method and observing the proper crop irrigation technology. It can be the solution for crop cultivation in clay loam soil. This study aimed to obtain water movement model in a minimally-tilled clay soil with strip shallow irrigation. The concept is limited soil-tillage with strip shallow irrigation method, water supply technique, and crop water requirement. Method used in this study includes developing water movement model (software development in a minimally-tilled clay soil with subsurface irrigation. In the final stages, research also conducted water movement analysis testing apparatus in the laboratory, field validation of the subsurface irrigation performance, and cultivation technique testing to chili pepper growth (Capsicum annuumL.. The development of water movement simulation on a limited strip-tillage with subsurface irrigation uses the concept to quantify the amount of water in the soil. The analysis of movement pattern was demonstrated on contour patterns. It showed that the wetting process can reach depth zone – 5 cm to the rooting zone. It was an important discovery on the development of minimum stripe tillage soil with subsurface irrigation. Specifically, it can be concluded that: the result of fitting by eyes to diffusivity graphic and water content obtained the required parameter values for soil physical properties.

    To illustrate the method of cohort reporting of persons with diabetes mellitus (DM) in a primary healthcare clinic in Amman, Jordan, serving Palestine refugees with the aim of improving quality of DM care services. A descriptive study using quarterly and cumulative case findings, as well as cumulative and 12-month analyses of cohort outcomes collected through E-Health in UNRWA Nuzha Primary Health Care Clinic. There were 55 newly registered patients with DM in quarter 1, 2012, and a total of 2851 patients with DM ever registered on E-Health because this was established in 2009. By 31 March 2012, 70% of 2851 patients were alive in care, 18% had failed to present to a healthcare worker in the last 3 months and the remainder had died, transferred out or were lost to follow-up. Cumulative and 12-month cohort outcome analysis indicated deficiencies in several components of clinical care: measurement of blood pressure, annual assessments for foot care and blood tests for glucose, cholesterol and renal function. 10-20% of patients with DM in the different cohorts had serious late complications such as blindness, stroke, cardiovascular disease and amputations. Cohort analysis provides data about incidence and prevalence of DM at the clinic level, clinical management performance and prevalence of serious morbidity. It needs to be more widely applied for the monitoring and management of non-communicable chronic diseases. © 2012 Blackwell Publishing Ltd.

    Among the most basic challenges of hydrology are the quantitative understanding of the processes of runoff generation and prediction of flow hydrographs. Traditional techniques have been widely applied for the estimation of runoff hydrographs of gauged catchments using historical rainfall-runoff data and unit hydrographs. Such procedures are questioned as to their reliability and their application to ungauged, arid and semiarid catchments. To overcome such difficulties, the use of physically based rainfall-runoff process of Faria Catchment using the lately developed KW-GIUH. Faria catchment, located in the northeastern part of the West Bank, Palestine, is characterized as a semiarid region with annual rainfall depths ranging on average from 150 to 640 mm at both ends of the catchment. The Geographical Information System (GIS) techniques were used to shape the geomorphological features of the catchment. A GIS based KW-GIUH hydrological model was used to stimulate the rainfall-runoff process in the three sub-catchments of Faria, namely: Al-Badan, Al-Faria and Al-Malaqi. The simulated runoff hydrographs proved that the GIS-based KW-GIUH model is applicable to semiarid regions and can be used to estimate the unit hydrographs in the West Bank catchments. (author)

    Full Text Available The mutation rate and genetic variability of hepatitis B virus (HBV are crucial factors for efficient treatment and successful vaccination against HBV. Until today, genetic properties of this virus among the Palestinian population remain unknown. Therefore, we performed genetic analysis of the overlapping S and polymerase genes of HBV, isolated from 40 Palestinian patients' sera. All patients were HBsAg positive and presented with a viral load above 105 HBV genome copies/ml. The genotyping results of the S gene demonstrated that HBV D1 was detected in 90% of the samples representing the most prominent subgenotype among Palestinians carrying HBV. Various mutations existed within the S gene; in five patients four known escape mutations including the common G145R and D144E were found. Furthermore, a ratio of 4.25 of non-synonymous to synonymous mutations in the S gene indicated a strong selection pressure on the HBs antigen loops of HBV strains circulating in those Palestinian patients. Although all patients were treatment-naïve, with the exception of one, several mutations were found in the HBV polymerase gene, but none pointed to drug resistance. The study presented here is the first report to address subgenotypes and mutation analyses of HBV S and polymerase genes in Palestine.

    Hospitals and health centers provide a variety of healthcare services and normally generate hazardous waste as well as general waste. General waste has a similar nature to that of municipal solid waste and therefore could be disposed of in municipal landfills. However, hazardous waste poses risks to public health, unless it is properly managed. The hospital waste management system encompasses many factors, i.e., number of beds, number of employees, level of service, population, birth rate, fertility rate, and not in my back yard (NIMBY) syndrome. Therefore, this management system requires a comprehensive analysis to determine the role of each factor and its influence on the whole system. In this research, a hospital waste management simulation model is presented based on the system dynamics technique to determine the interaction among these factors in the system using a software package, ithink. This model is used to estimate waste segregation as this is important in the hospital waste management system to minimize risk to public health. Real data has been obtained from a case study of the city of Nablus, Palestine to validate the model. The model exhibits wastes generated from three types of hospitals (private, charitable, and government) by considering the number of both inpatients and outpatients depending on the population of the city under study. The model also offers the facility to compare the total waste generated among these different types of hospitals and anticipate and predict the future generated waste both infectious and non-infectious and the treatment cost incurred.

    Eight accessions of olive trees from three common varieties in Palestine, Nabali Baladi, Nabali Mohassan and Surri, were genetically evaluated using five simple sequence repeat (SSR) markers. A total of 17 alleles from 5 loci were observed in which 15 (88.2%) were polymorphic and 2 (11.8%) were monomorphic. An average of 3.4 alleles per locus was found ranging from 2.0 alleles with the primers GAPU-103 and DCA-9 to 5.0 alleles with U9932 and DCA-16. The smallest amplicon size observed was 50 bp with the primer DCA-16, whereas the largest one (450 bp) with the primer U9932. Cluster analysis with the unweighted pair group method with arithmetic average (UPGMA) showed three clusters: a cluster with four accessions from the ‘Nabali Baladi’ cultivar, another cluster with three accessions that represents the ‘Nabali Mohassen’ cultivar and finally the ‘Surri’ cultivar. The similarity coefficient for the eight olive tree samples ranged from a maximum of 100% between two accessions from Nabali Baladi and also in two other samples from Nabali Mohassan, to a minimum similarity coefficient (0.315) between the Surri and two Nabali Baladi accessions. The results in this investigation clearly highlight the genetic dissimilarity between the three main olive cultivars that have been misidentified and mixed up in the past, based on conventional morphological characters.

This study aims to investigate how use of the Kindle can enhance individuals’ English language learning—more specifically their attitudes, reading comprehension, vocabulary development and pronunciation performance—in the context of informal and lifelong learning in Palestine, and to explore the further potential of scaling up the use of e-readers at a national level. At the piloting stage of this initiative, the study operated at two levels (micro and meso of the M3 evaluation framework. Mixed methods were used: qualitative data were obtained through a case study of the practices and perceptions of two teachers in two classrooms in the Qalqilia center and quantitative data were collected through a survey of 114 learners. The study shows that the Kindle’s technological affordances are effective in creating a flexible, authentic and interactive environment for English language learning, provided that teachers change their teaching methods to take full advantage of the features of mobile technologies to create innovative learning approaches aligned with the needs of the e-generation. It was also found that despite some concerns with the usability issue, attitudes towards learning English changed positively and learners’ vocabulary and pronunciation improved.

    This study presents the seasonal variations of indoor radon levels in dwellings located in the Ramallah province and East Jerusalem suburbs, Palestine. The measurements were performed during the summer and winter of the year 2006/2007 using CR-39 solid-state-nuclear-track detectors. The total number of investigated buildings is 75 in summer and 81 in winter. A total number of 142 dosemeters are installed in dwellings for each season for a period of almost 100 d. The radon concentration levels in summer varied from 43 to 192 Bq m -3 for buildings in the Ramallah province and from 30 to 655 Bq m -3 for East Jerusalem suburbs. In winter, the radon concentration levels are found to vary from 38 to 375 Bq m -3 in the Ramallah buildings and from 35 to 984 Bq m -3 in East Jerusalem suburbs. The obtained results for radon concentration levels in most places are found to be within the accepted international levels. (authors)

    1991-01-01

    Membrane air stripping has recently been proposed as a possible method to remove volatile organic chemicals (VOCs) and radon from drinking water supplies. Current and anticipated regulatory requirements, driven by health consequences, make the removal of these contaminants mandatory. This work examines the use of plate and frame membrane air stripping for the removal of VOCs and radon from a water supply. The theoretical basis of membrane air stripping and a literature review are included. The advantages of membrane air stripping versus other methods of removal, as well as the advantages of a plate and frame configuration versus a hollow fiber configuration for membrane air stripping are discussed. Multiple regression/correlation techniques are used to model mass transfer coefficients and fluid resistances. An economic evaluation is performed using the developed models. The costs of comparable membrane and packed tower air stripping systems are 4.86 cents per thousand gallons versus 4.36 cents per thousand gallons, respectively. This work indicates that plate and frame membrane air stripping may, in fact, prove to be an economical alternative to packed tower aeration and carbon adsorption for the removal of VOCs and radon

    Poor screw purchase because of osteoporosis presents difficulties in ankle fracture fixation. The aim of our study was to determine if cortical thickness, unicortical versus bicortical purchase, and bone mineral density are predictors of inadvertent screw stripping and overtightening. Ten paired cadaver ankles (average donor age, 81.7 years; range, 50-97 years) were used for the study. Computed tomography scanning with phantoms of known density was used to determine the bone density along the distal fibula. A standard small-fragment, 7-hole, one-third tubular plate was applied to the lateral surface of the fibula, with 3 proximal bicortical cortical screws and 2 distal unicortical cancellous screws. A posterior plate, in which all 5 screws were cortical and achieved bicortical purchase, was subsequently applied to the same bones and positioned so that the screw holes did not overlap. A torque sensor was used to measure the torque of each screw during insertion (Ti) and then stripping (Ts). The effect of bone density, screw location, cortical thickness, and unicortical versus bicortical purchase on Ti and Ts was checked for significance (P screws were inadvertently stripped and 12% were overtightened. Despite 21% of the screws being stripped or being at risk for stripping, we found no significant predictors to warn of impending screw stripping. Additional work is needed to identify clinically useful predictors of screw stripping. PMID:23569675

    In the reductive stripping of uranium from an organic extractant in a uranium recovery process, the use of phosphoric acid having a molarity in the range of 8 to 10 increases the efficiency of the reductive stripping and allows the strip step to operate with lower aqueous to organic recycle ratios and shorter retention time in the mixer stages. Under these operating conditions, less solvent is required in the process, and smaller, less expensive process equipment can be utilized. The high strength H/sub 3/PO/sub 4/ is available from the evaporator stage of the process.

    The CMS Silicon Strip Tracker (SST), comprising 9.6 million readout channels from 15148 modules covering an area of about 200 square meters, needs to be precisely calibrated in order to correctly interpret and reconstruct the events recorded from the detector, ensuring that the SST performance fully meets the physics research program of the CMS experiment. Calibration constants may be derived from promptly reconstructed events as well as from pedestal runs gathered just before the acquisition of physics runs. These calibration procedures were exercised in summer and winter 2009, when the CMS detector was commissioned using cosmic muons and proton-proton collisions at a center-of-mass energies of 900 GeV and 2.36 TeV. During these data taking periods the performance of the SST was carefully studied: the noise of the detector, the data integrity, the signal-to-noise ratio, the hit reconstruction efficiency, the calibration workflows have been all checked for stability and for different conditions, at the module...

    The rolled strip pulse forming line (RSPFL) has advantages of compactness, portability, and long pulse achievability which could well meet the requirements of industrial application of the pulse power technology. In this paper, an improved RSPFL with an additional insulator between the grounded conductors is investigated numerically and experimentally. Results demonstrate that the jitter on the flat-top of the output voltage waveform is reduced to 3.8% due to the improved structure. Theoretical analysis shows that the electromagnetic coupling between the conductors of the RSPFL strongly influences the output voltage waveform. Therefore, the new structure was designed to minimize the detrimental effect of the electromagnetic coupling. Simulation results show that the electromagnetic coupling can be efficiently reduced in the improved RSPFL. Experimental results illustrate that the improved RSPFL, with dimensions and weight of Φ 290 × 250 mm and 16 kg, when used as a simple pulse forming line, could generate a well shaped quasi-square pulse with output power of hundreds of MW and pulse duration of 250 ns. Importantly, the improved RSPFL was successfully used as a Blumlein pulse forming line, and a 10.8 kV, 260 ns quasi-square pulse was obtained on a 2 Ω dummy load. Experiments show reasonable agreement with numerical analysis.

    1984-01-01

    The anodic stripping voltammetry (ASV) is routinely applied to control of Cu(II) in heavy water in the primary cooling loop of the Nuclear Power Reactor. The anodic stripping voltammetry (ASV) is a very well-known technique in electroanalytical chemistry. However, due to the complexity of the phenomena, it is practised with the fundamentals of empiric considerations. A geometric model for the anodic stripping voltammetry (ASV) from thin film electrodes which can be calculated by explicit digital simulation method is proposed as a possibility of solving the electrochemically reversible, cuasi-reversible and irreversible reactions under linear potential scan and multiple potential scans. (Until now the analytical mathematical method was applied to reversible reactions). All the results are compared with analytical solutions and experimental results and it permits to conclude that the anodic stripping voltammetry (ASV) can be studied with the simplicity and potentialities of explicit digital simulation methods.

    The CMS silicon strip tracker, providing a sensitive area of approximately 200 m 2 and comprising 10 million readout channels, has recently been completed at the tracker integration facility at CERN. The strip tracker community is currently working to develop and integrate the online and offline software frameworks, known as XDAQ and CMSSW respectively, for the purposes of data acquisition and detector commissioning and monitoring. Recent developments have seen the integration of many new services and tools within the online data acquisition system, such as event building, online distributed analysis, an online monitoring framework, and data storage management. We review the various software components that comprise the strip tracker data acquisition system, the software architectures used for stand-alone and global data-taking modes. Our experiences in commissioning and operating one of the largest ever silicon micro-strip tracking systems are also reviewed

    Nayfeh, A. H.; Reed, H. L.

    1982-01-01

    Linear triple deck, closed form solutions for mean-flow quantities are developed for axisymmetric incompressible flow past a body with porous strips. The solutions account for upstream influence and are linear superpositions of the flow past the body without suction plus the perturbations due to the suction strips. Flow past the suctionless body is calculated using the Transition Analysis Program System, and a simple linear optimization scheme to determine number, spacing, and mass flow rate through the strips on an axisymmetric body is developed using the linear, triple-deck, closed-form solutions. The theory is demonstrated by predicting optimal strip distributions, and the effect of various adverse pressure-gradient situations on stability is studied.

  1. High Pressure Water Stripping Using Multi-Orifice Nozzles

    Science.gov (United States)

    Hoppe, David

    1999-01-01

    The use of multi-orifice rotary nozzles greatly increases the speed and stripping effectiveness of high pressure water blasting systems, but also greatly increases the complexity of selecting and optimizing the operating parameters. The rotational speed of the nozzle must be coupled with its transverse velocity as it passes across the surface of the substrate being stripped. The radial and angular positions of each orifice must be included in the analysis of the nozzle configuration. Orifices at the outer edge of the nozzle head move at a faster rate than the orifices located near the center. The energy transmitted to the surface from the impact force of the water stream from an outer orifice is therefore spread over a larger area than energy from an inner orifice. Utilizing a larger diameter orifice in the outer radial positions increases the total energy transmitted from the outer orifice to compensate for the wider distribution of energy. The total flow rate from the combination of all orifices must be monitored and should be kept below the pump capacity while choosing orifice to insert in each position. The energy distribution from the orifice pattern is further complicated since the rotary path of all the orifices in the nozzle head pass through the center section. All orifices contribute to the stripping in the center of the path while only the outer most orifice contributes to the stripping at the edge of the nozzle. Additional orifices contribute to the stripping from the outer edge toward the center section. With all these parameters to configure and each parameter change affecting the others, a computer model was developed to track and coordinate these parameters. The computer simulation graphically indicates the cumulative affect from each parameter selected. The result from the proper choices in parameters is a well designed, highly efficient stripping system. A poorly chosen set of parameters will cause the nozzle to strip aggressively in some areas

    The Feshbach projection formalism is used to calculate the form factors for the (d,n) stripping process to isolated analog resonances. These are used in a standard DWBA stripping calculation in which the radial integration over all space is accomplished by including outerspace contributions evaluated along the complex contours of Vincent and Fortune. It turns out that the shape and magnitude of the predicted cross section is quite insensitive to the continuum proton wave emanating from the resonant residual state. (Author) [pt

  6. A new strips tracker for the upgraded ATLAS ITk detector

    Science.gov (United States)

    David, C.

    2018-01-01

    The ATLAS detector has been designed and developed to function in the environment of the present Large Hadron Collider (LHC). At the next-generation tracking detector proposed for the High Luminosity LHC (HL-LHC), the so-called ATLAS Phase-II Upgrade, the fluences and radiation levels will be higher by as much as a factor of ten. The new sub-detectors must thus be faster, of larger area, more segmented and more radiation hard while the amount of inactive material should be minimized and the power supply to the front-end systems should be increased. For those reasons, the current inner tracker of the ATLAS detector will be fully replaced by an all-silicon tracking system that consists of a pixel detector at small radius close to the beam line and a large area strip tracker surrounding it. This document gives an overview of the design of the strip inner tracker (Strip ITk) and summarises the intensive R&D activities performed over the last years by the numerous institutes within the Strips ITk collaboration. These studies are accompanied with a strong prototyping effort to contribute to the optimisation of the Strip ITk's structure and components. This effort culminated recently in the release of the ATLAS Strips ITk Technical Design Report (TDR).

  7. Efficient ozone, sulfate, and ammonium free resist stripping process

    Dattilo, Davide; Dietze, Uwe

    2014-07-01

    In recent years, photomask resist strip and cleaning technology development was substantially driven by the industry's need to prevent surface haze formation through the elimination of sulfuric acid and ammonium hydroxide from these processes. As a result, conventional SPM (H2SO4 + H2O2) was replaced with Ozone water (DIO3) for resist stripping and organic removal to eliminate chemical haze formation [1, 2]. However, it has been shown that DIO3 basted strip and clean process causes oxidative degradation of photomask materials [3, 4]. Such material damage can affect optical properties of funcitional mask layers, causeing CD line-width, phase, transmission and reflection changes, adversely affecting image transfer during the Lithography process. To overcome Ozone induced surface damage, SUSS MicroTec successfully developed a highly efficient strip process, where photolysis of DIO3 is leading to highly reactive hydroxyl radical formation, as the main contribution to hydrocarbon removal without surface damage [5]. This technology has been further extended to a final clean process, which is utilizing pure DI water for residual organic material removal during final clean [6]. Recently, SUS MicroTec did also successfully release strip and clean processes which completely remove NH4OH, eliminating any chemicals known today to induce haze [7]. In this paper we show the benefits of these new technologies for highly efficient sulfate and ammonium free stripping and cleaning processes.

    1994-04-01

    This is a comprehensive effort to develop direct strip casting to the point where a pilot scale program for casting carbon steel strip could be initiated. All important aspects of the technology were being investigated, however the program was terminated early due to a change in the business strategy of the primary contractor, Armco Inc. (focus to be directed at specialty steels, not low carbon steel). At termination, the project was on target on all milestones and under budget. Major part was casting of strip at the experiment casting facility. A new caster, capable of producing direct cast strip of up to 12 in. wide in heats of 1000 and 3000 lb, was used. A total of 81 1000-1200 lb heats were cast as well as one test heat of 3000 lb. Most produced strip of from 0.016 to 0.085 in. thick. Process reliability was excellent for short casting times; quality was generally poor from modern hot strip mill standards, but the practices necessary for good surface quality were identified.

    The purpose of this study is to examine the unit costs of a multi-service hospital in Palestine for the period 2005-2007. We investigate the cost structure of the Rafidya Hospital located in Nablus city, for both inpatient and outpatient departments. This study uses cost-volume-profit (CVP) analysis, also known as breakeven analysis. CVP analysis requires examining total costs, along with fixed and variable costs. CVP analysis illuminates how changes in assumptions about cost behaviour and the relevant range in which those assumptions are valid affect the relationships among revenues, variable costs and fixed costs at various production levels. For the hospital of interest, we find that fixed costs account for 70% of total costs, and variable costs were 30% of total costs. Inpatient departments accounted for 86% of total costs, and outpatient departments were 14% of total costs. Results of the breakeven analysis illustrate that several departments charge sufficient fees to cover all unit costs. Results provide useful information about unit cost based on four categories: (1) unit cost per admission of each department, (2) unit cost per patient day of each department, (3) unit cost per admission with annual capital cost of each department and (4) unit cost per patient day with annual capital cost. Our results provide hospital cost information that can be used by decision-makers to provide and expand healthcare services, in an effort to increase sustainability and profitability. The use of cost analysis by administrators and regulators will improve the quality of financial information, as well as enhance the efficient use of scarce resources.

    This study examines the effect of the Maternal and Child Health (MCH) handbook--a home-based health record--on women's knowledge and behavior in the Jericho and Ramallah Governorates of Palestine. This study uses a repeated, cross-sectional data set in which pre- and post-intervention situations are incorporated on two groups: those exposed and those not exposed to the MCH handbook. We employed a difference-in-difference regression analysis utilizing a pre-tested knowledge, attitude, and practice survey of women at 24 MCH 'treatment' centers (N=260, 270, pre-/post-) in comparison with the women at 6 MCH centers (N=70, 70, pre-/post-) where the MCH handbook was not released. A trained facilitator conducted a series of focus group discussions with 42 women who were the clients of MCH services and 25 health providers, both from the intervention area, to confirm the results obtained from the quantitative study. Knowledge related to MCH such as the importance of exclusive breastfeeding and how to cope with the risks of rupture of membranes during pregnancy increased among MCH handbook users, especially among less-educated women. The MCH handbook may be an effective tool for communication with health providers and husbands, for both highly educated and less-educated women during their first pregnancy. Our results suggest that although less-educated women rarely read the handbook themselves at home, they became familiar with health information and options related to MCH through personalized guidance that was provided by health providers at health facilities utilizing MCH handbook. The MCH handbook may be an effective tool to improve (i) communication between the client and the health provider and (ii) women's knowledge- and health-seeking behaviors related to maternal, newborn, and child health.

    The planned HL-LHC (High Luminosity LHC) is being designed to maximise the physics potential of the LHC with 10 years of operation at instantaneous luminosities of 7.5x1034cm−2s−1. A consequence of this increased luminosity is the expected radiation damage requiring the tracking detectors to withstand hadron equivalences to over 1x1015 1 MeV neutron equivalent per cm2 in the ATLAS Strips system. The silicon strip tracker exploits the concept of modularity. Fast readout electronics, deploying 130nm CMOS front-end electronics are glued on top of a silicon sensor to make a module. The radiation hard n-in-p micro-strip sensors used have been developed by the ATLAS ITk Strip Sensor collaboration and produced by Hamamatsu Photonics. A series of tests were performed at the DESY-II and CERN SPS test beam facilities to investigate the detailed performance of a strip module with both 2.5cm and 5cm length strips before and after irradiation with 8x1014neqcm−2 protons and a total ionising dose of 37.2MRad.

    Radon concentration and annual effective doses were measured in drinking water in the Southern Part of West Bank – Palestine, by using both passive and active techniques. 184 samples were collected from various sources i.e. tap water, groundwater, rain waters and mineral waters. It is found that the annual effective dose resulting from inhalation and ingestion of radon emanated from all types of drinking water is negligible compared to the total annual effective dose from indoor radon in the region. Results reveal that there is no significant public health risk from radon ingested and inhalation with drinking water in the study region. - Highlights: • The radon concentrations are measured for drinking water samples in the southern part of West Bank – Palestine. • We conclude that there is no significant public health risk from radon ingested and inhalation with drinking water in the study region. • We recommend that this study can be used as a baseline for information or further research

    Most health-care organisations are increasingly interested in assessing the quality of their services. Patient satisfaction has a central role in the quality assessment in health care because it reflects the appropriateness of services from the clients' perspectives. The aim of this study was to assess the level of satisfaction in patients with non-communicable diseases (mainly diabetes and hypertension) who receive services from UNRWA health centres in Gaza governorates. In this cross-sectional study we chose a random sample of participants who presented to the randomly selected six health centres for treatment of non-communicable diseases. Through an exit interviewing technique, participants were chosen according to the study eligibility criteria and were requested to complete a questionnaire. The total instrument reliability (Cronbach's Alpha) was very high (0·936). To examine construct validity, we used Factor Analysis Principal Component Extraction with Varimax Rotation and Kaiser Normalisation with a cutoff point of 0·4. The reported variance was 42·28%, indicating high validity. Ethical approval from the Palestinian Ministry of Health (the Helsinki committee) was obtained, and verbal consent was obtained from the participants. 327 (82%) of 400 eligible patients completed the questionnaire. The reported overall satisfaction level with services for non-communicable diseases was moderately high (72%). The study extracted six domains that could constitute a framework for patient satisfaction with services at UNRWA clinics for non-communicable diseases. Elicited satisfaction scores about these domains varied and ranged from 57% to 84%. Although high satisfaction levels were found with general impressions, accessibility, communication, and interpersonal relationships, patients had a low level of satisfaction with the technical quality of services, clinic environment, and convenience of the services.

    Elliptical cluster galaxies are progressively stripped of their atmospheres due to their motion through the intracluster medium (ICM). Deep X-ray observations reveal the fine-structure of the galaxy’s remnant atmosphere and its gas tail and wake. This fine-structure depends on dynamic conditions (galaxy potential, initial gas contents, orbit through the host cluster), orbital stage (early infall, pre-/post-pericenter passage), and ICM plasma properties (thermal conductivity, viscosity, magnetic field structure). We aim to disentangle dynamic and plasma effects in order to use stripped ellipticals as probes of ICM plasma properties. This first paper of a series investigates the hydrodynamics of progressive gas stripping by means of inviscid hydrodynamical simulations. We distinguish a long-lasting initial relaxation phase and a quasi-steady stripping phase. During quasi-steady stripping, the ICM flow around the remnant atmosphere resembles the flow around solid bodies, including a “deadwater” region in the near wake. Gas is stripped from the remnant atmosphere predominantly at its sides via Kelvin–Helmholtz instabilities. The downstream atmosphere is largely shielded from the ICM wind and thus shaped into a tail. Observationally, both this “remnant tail” and the stripped gas in the wake can appear as a “tail”, but only in the wake can galactic gas mix with the ambient ICM. While the qualitative results are generic, the simulations presented here are tailored to the Virgo elliptical galaxy M89 (NGC 4552) for the most direct comparison to observations. Papers II and III of this series describe the effect of viscosity and compare to Chandra and XMM-Newton observations, respectively.

    Combustible nitrocellulose ordnance casings offer advantages of: light weight, low cost, low detectability, and quick cycling of rounds by immediate disposal. However, mechanical strength is degraded with time by the action of humidity and nitroester diffusion through the casing to adhesives. The primary development effort of this study is a means to detect nitroester migration to the crucial skive joint which binds an assortment of warhead choices to propellant casings. This work has developed a prototype colorimetric indicator strip which, when applied in a field environment, produces a purple tint proportional to casing nitroester concentration, and inversely proportional to remaining adhesive joint strength. This work addressed the three steps in indicator strip use: (1) A suggested protocol for indicator strip preparation was developed. Various coatings, support reagents, and backings were examined resulting in a choice of polyethylene tape coating over separate AB- and C-impregnated cellulose punches. Various methods of punch creation and impregnation were tried resulting in stirred aqueous solutions and suspensions of AB and C, respectively. (2) Suggested protocols for indicator strip application to lab backings and field casings were developed. After chemical stripper was applied to the alumina-polyurethane paint on casings, C and AB punches were stacked and double-tape sealed. (3) A means for indicator strip monitoring was developed. From known time of indicator reaction, casing humidity, and indicator color, a means for field concentration determination was determined. Lab time-lapse photography was used to calibrate the indicator at a single level of humidity.

  18. Theoretical study of H- stripping with a wiggler magnet

    International Nuclear Information System (INIS)

    Hutson, R.L.

    1991-01-01

    The first step for injecting protons into the LAMPF Proton Storage Ring (PSR) at LANL is to strip a beam of 800-MeV H - ions to H 0 with a 1.8-T dipole magnet. Because of the finite lifetime of energetic H - ions in the magnetic field, their trajectories bend before stripping causing the angular spread of the beam, and therefore its emittance, to grow during the stripping process. In the case of the PSR, the horizontal beam emittance grows by a factor of roughly three during injection. As a consequence, beam losses in the ring are significantly greater than they would be if there were not emittance growth. A speculative technique is proposed in which the beam divergence growth and resulting emittance growth is reduced by stripping the H - in a wiggler magnet whose transverse field alternates in direction as a function of position along the beam axis. The wiggler field configuration is adjusted so that the angular beam spread introduced during passage through one unidirectional-field increment of path is relatively small and so that 99.99% of the beam is stripped after passing through the whole magnet. With careful field design the net added angular beam spread is reduced because the incremental angular spreads are painted back and forth over the same small range. In the hypothetical case described, the calculated emittance growth and beam loss increase are significantly smaller than those calculated for a conventional stripper magnet. 3 refs., 3 figs

    Cutaneous leishmaniases (CL) are vector-borne parasitic diseases endemic in many countries of the Middle East including Palestine. Between 1994 and 2015, 2160 clinically suspected human cases of CL from the Jericho District were examined. Stained skin tissue smears and aspirates were checked by microscopy and cultured for promastigotes, respectively. For leishmanial species identification, amplification products from a PCR-ITS1 followed by RFLP analysis using Hae III. Data were analyzed using Epi Info free-software. The overall infection rate was 41.4% (895/2160), 56.3% (504/895) of the cases were male, 43.7% (391/895) female, 60.5% (514/849) children under age 14, 41.3% (259/627) of the cases were caused by Leishmaniamajor and 57.3% (359/627) by Leishmaniatropica. The case numbers peaked in 1995, 2001, 2004, and 2012. Statistically-significant clusters of cases caused by L. major were restricted to the Jericho District; those caused by L. tropica were from the districts of Jericho, Bethlehem, Nablus and Tubas. CL is seasonal and trails the sand fly season. Distribution of cases was parabolic with fewest in July. The monthly total number of cases of CL and just those caused by L. major correlated significantly with temperature, rainfall, relative humidity, evaporation, wind speed and sunshine (P<0.05, r 2 =0.7-0.9 and P<0.05, r 2 =0.5-0.8, respectively). Cases caused by L. tropica, significantly, had a single lesion compared to cases caused by L. major (P=0.0001), which, significantly, had multiple lesions (P=0.0001). This and previous studies showed that CL is present in all Palestinian districts. The surveillance of CL has increased public awareness and molecular biological methodology for leishmanial species identification is an essential addition to classical diagnosis. The overall results are discussed, correlated to climatic and environmental changes and large-scale human activities. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available The increasing spread of β-lactamase-producing pathogens represents an emerging serious public health threat specially to treat nosocomial infections. This study was carried out to determine the prevalence and molecular characterization of β-lactamase-producing Enterobacter cloacae isolates; and to estimate the prevalence of integrons in these isolates. A total of 41 clinical isolates of E. cloacae were recovered from different hospitals in the North West Bank-Palestine. Enterobacter cloacae isolates were identified using API 20E system and β-lactamase genes (ESBL, MBL and AmpC β-lactamase genes detection was carried out using multiplex PCR technique. Results of the current research showed that the prevalence of β-lactamases among the studied clinical E. cloacae isolates was (34/41 82.9%. The prevalence of ESBLs, MBLs and AmpC β-lactamase genes was 80.5%, 14.6% and 9.8%, respectively. For ESBL, blaTEM gene was the most dominant with a prevalence rate 63.4%. Other detected genes were 31.7%, 29.3, and 7.3% for blaOXA, blaSHV and blaCTX-M, respectively. Coexistence of 2 ESBL genes or more was detected in 39% of E. cloacae isolates. For AmpC β-lactamases only blaDHA gene was detected with a prevalence 4.9%, whereas for MBLs, the prevalence of blaIMP alone was 9.8%, blaSPM and blaIMP, and blaSIM and blaSPM together was 2.4% for each. A total of 8 isolates (19.5% showed coexistence with at least another type of β-lactamases. In this study, class 1 integrons were detected only in β-lactamase-producing E. cloacae isolates with prevalence of (17/34 50% among β-lactamase producers. ERIC-PCR typing of 34 clinical isolates of E. cloacae harbored different β-lactamase genes, were grouped into 5 ERIC PCR profiles (clusters at a 70% similarity level. Results of ERIC-PCR typing showed that at lease there are 3 identical clones circulating among these hospitals and the predominant clone is C1CL1.

    Full Text Available Background: Essential oils (EOs are complex mixtures of several components gifted with a wide array of biological activities. The present research was designed to evaluate whether commercial essential oils could be effective by examining their in vitro antioxidant, cytotoxic, and apoptotic properties of nine commercially available EOs in Palestine, namely, African rue, basil, chamomile, fennel, fenugreek, ginger, spearmint, sage, and thyme, and to assure their effective use. Methods: The cytotoxic activity was determined using HT29-19(A non-muco secreting and HT29-muco secreting (MS cell lines. MTT, and trypan blue tests, and DPPH radical scavenging have also been assayed on the studied EOs. Results: In this work chamomile oil showed the lowest IC50 at the content of 60 µL/mL, while all other EOs reached such a decrease when 70–80 µL/mL was used on HT-29 (MS cell lines. In HT-29 19(A cells, 50% of viability was obtained when 80 µL/mL of ginger and African rue was used, while all other EOs needed more than 80 µL/mL to reach such a decline in viability. Otherwise, an MTT assay on HT-29 (MS displayed ginger EO with the lowest IC50, followed by African rue and sage, with 40, 48 and 53 µL/mL, respectively. Otherwise, for the rest of the EOs, the IC50 was obtained by assaying around 80 µL/mL. Ginger showed the lowest IC50 with 60 µL/mL and thyme was the highest with 77 µL/mL when HT-29 19(A cells were used. Conclusion: The most active EOs were found to be ginger, chamomile oil, and African rue. In general, the results demonstrate that most commercial EOs tested in this work possess low, or no biological activities; this may be due to processing, storage conditions, and handling or other reasons, which may cause losses in the biological and pharmacological properties that endemically exist in the Eos; hence, more investigation is still required on commercial EOs before they are recommended to the public.

    Based on the model of lattice dynamics together with the transfer matrix technique, we investigate the thermal conductances of phonons in quasi-one-dimensional disordered graphene strips with armchair edges using Landauer formalism for thermal transport. It is found that the contributions to thermal conductance from the phonon transport near von Hove singularities is significantly suppressed by the presence of disorder, on the contrary to the effect of disorder on phonon modes in other frequency regions. Besides the magnitude, for different widths of the strips, the thermal conductance also shows different temperature dependence. At low temperatures, the thermal conductance displays quantized features of both pure and disordered graphene strips implying that the transmission of phonon modes at low frequencies are almost unaffected by the disorder

    Silicon strip detectors are widely used as part of the inner tracking layers in particle physics experiments. For applications at the luminosity upgrade of the Large Hadron Collider (LHC), the sLHC, silicon detectors with extreme radiation hardness are required. The 3D detector design, where electrodes are processed from underneath the strips into the silicon bulk material, provides a way to enhance the radiation tolerance of standard planar silicon strip detectors. Detectors with several innovative 3D designs that constitute a simpler and more cost-effective processing than the 3D design initially proposed were connected to read-out electronics from LHC experiments and subsequently tested. Results on the amount of charge collected, the noise and the uniformity of charge collection are given.

    Full Text Available This study addresses the use of combined stripping systems to investigate the technical feasibility of extracting thick coal seams underlying deep overburden strata. The possibility of using multiple draglines in tandem with bucket wheel excavator systems is explored. Pit geometry design alternatives incorporating a triple dragline excavation fleet with bucket wheel excavator-cross pit spreader subsystems (BWE+XPS are examined. A production simulation algorithm, which emphasizes synchronizing excavator units in the triple dragline system, is developed. The combined methodology is evaluated in Sector-D of the Afşin-Elbistan lignite basin, one of the most important resources for electricity production in Turkey. The results reveal that a combined stripping fleet may successfully perform overburden stripping at the predetermined rate and uncover coal seams.

    In March 2007 the assembly of the Silicon Strip Tracker was completed at the Tracker Integration Facility at CERN. Nearly 15% of the detector was instrumented using cables, fiber optics, power supplies, and electronics intended for the operation at the LHC. A local chiller was used to circulate the coolant for low temperature operation. In order to understand the efficiency and alignment of the strip tracker modules, a cosmic ray trigger was implemented. From March through July 4.5 million triggers were recorded. This period, referred to as the Sector Test, provided practical experience with the operation of the Tracker, especially safety, data acquisition, power, and cooling systems. This paper describes the performance of the strip system during the Sector Test, which consisted of five distinct periods defined by the coolant temperature. Significant emphasis is placed on comparisons between the data and results from Monte Carlo studies.

    Full Text Available According to the movement mechanism of strip and rollers in tandem mill, the strip between two stands was simplified to axially moving Euler beam and the rollers were simplified to the inertial component on the fixed axis rotation, namely, inertial boundary. Nonlinear vibration mechanical model of Euler beam with inertial boundary conditions was established. The transverse and longitudinal motion equations were derived based on Hamilton’s principle. Kantorovich averaging method was employed to discretize the motion equations and the inertial boundary equations, and the solutions were obtained using the modified iteration method. Depending on numerical calculation, the amplitude-frequency responses of Euler beam were determined. The axial velocity, tension, and rotational inertia have strong influences on the vibration characteristics. The results would provide an important theoretical reference to control and analyze the vertical vibration of moving strip in continuous rolling process.

  8. ISM stripping from cluster galaxies and inhomogeneities in cooling flows

    Analyses of the x ray surface brightness profiles of cluster cooling flows suggest that the mass flow rate decreases towards the center of the cluster. It is often suggested that this decrease results from thermal instabilities, in which denser blobs of gas cool rapidly and drop below x ray emitting temperatures. If the seeds for the thermal instabilities are entropy perturbations, these perturbations must enter the flow already in the nonlinear regime. Otherwise, the blobs would take too long to cool. Here, researchers suggest that such nonlinear perturbations might start as blobs of interstellar gas which are stripped out of cluster galaxies. Assuming that most of the gas produced by stellar mass loss in cluster galaxies is stripped from the galaxies, the total rate of such stripping is roughly M sub Interstellar Matter (ISM) approx. 100 solar mass yr(-1). It is interesting that the typical rates of cooling in cluster cooling flows are M sub cool approx. 100 solar mass yr(-1). Thus, it is possible that a substantial portion of the cooling gas originates as blobs of interstellar gas stripped from galaxies. The magnetic fields within and outside of the low entropy perturbations can help to maintain their identities, both by suppressing thermal conduction and through the dynamical effects of magnetic tension. One significant question concerning this scenario is: Why are cooling flows seen only in a fraction of clusters, although one would expect gas stripping to be very common. It may be that the density perturbations only survive and cool efficiently in clusters with a very high intracluster gas density and with the focusing effect of a central dominant galaxy. Inhomogeneities in the intracluster medium caused by the stripping of interstellar gas from galaxies can have a number of other effects on clusters. For example, these density fluctuations may disrupt the propagation of radio jets through the intracluster gas, and this may be one mechanism for producing Wide

    To provide the best spatial resolution for the particle trajectory reconstruction and a very fast readout, the inner tracking system of CMS is build up of silicon detectors with a pixel tracker in the center surrounded by a strip tracker. The silicon strip tracker consists of so-called modules representing the smallest detection unit of the tracking device. These modules are mounted on higher-level structures called shells in the tracker inner barrel (TIB), rods in the tracker outer barrel (TOB), disks in the tracker inner disks (TID) and petals in the tracker end caps (TEC). The performance of the participating two shells of the TIB, four rods of the TOB and two petals of the TEC (representing about 1% of the final strip tracker) could be studied in different magnetic fields over a period of approximately two month using cosmic muon signals. The last test before inserting the tracker in the CMS experiment was the Tracker Slice Test performed in spring/summer 2007 at the Tracker Integration Facility (TIF) at CERN after installing all subdetectors in the tracker support tube. Approximately 25% of the strip tracker +z side was powered and read out using a cosmic ray trigger built up of scintillation counters. In total, about 5 million muon events were recorded under various operating conditions. These events together with results from commissioning runs were used to study the detector response like cluster charges, signal-to-noise ratios and single strip noise behaviour as well as to identify faulty channels which turned out to be in the order of a few per mille. The performance of the silicon strip tracker during these different construction stages is discussed in this thesis with a special emphasis on the tracker end caps. (orig.)

  10. Experimental evidence that wildflower strips increase pollinator visits to crops.

    Wild bees provide a free and potentially diverse ecosystem service to farmers growing pollination-dependent crops. While many crops benefit from insect pollination, soft fruit crops, including strawberries are highly dependent on this ecosystem service to produce viable fruit. However, as a result of intensive farming practices and declining pollinator populations, farmers are increasingly turning to commercially reared bees to ensure that crops are adequately pollinated throughout the season. Wildflower strips are a commonly used measure aimed at the conservation of wild pollinators. It has been suggested that commercial crops may also benefit from the presence of noncrop flowers; however, the efficacy and economic benefits of sowing flower strips for crops remain relatively unstudied. In a study system that utilizes both wild and commercial pollinators, we test whether wildflower strips increase the number of visits to adjacent commercial strawberry crops by pollinating insects. We quantified this by experimentally sowing wildflower strips approximately 20 meters away from the crop and recording the number of pollinator visits to crops with, and without, flower strips. Between June and August 2013, we walked 292 crop transects at six farms in Scotland, recording a total of 2826 pollinators. On average, the frequency of pollinator visits was 25% higher for crops with adjacent flower strips compared to those without, with a combination of wild and commercial bumblebees (Bombus spp.) accounting for 67% of all pollinators observed. This effect was independent of other confounding effects, such as the number of flowers on the crop, date, and temperature. Synthesis and applications. This study provides evidence that soft fruit farmers can increase the number of pollinators that visit their crops by sowing inexpensive flower seed mixes nearby. By investing in this management option, farmers have the potential to increase and sustain pollinator populations over time.

    Highlights: • A visual strip sensor for on-site detection of iron has been developed and made. • The sensor is easy to synthesize, portable and recyclable with shelf life >1 year. • Visual detection limit for iron using the present sensor is 50 ng mL{sup −1}. • Visual strip sensor was applied to ground water and fruit juices. - Abstract: A visual strip has been developed for sensing iron in different aqueous samples like natural water and fruit juices. The sensor has been synthesized by UV-radiation induced graft polymerization of acrylamide monomer in microporous poly(propylene) base. For physical immobilization of iron selective reagent, the in situ polymerization of acrylamide has been carried out in the presence of 1,10-phenanthroline. The loaded strip on interaction with Fe(II) in aqueous solution turned into orange red color and the intensity of the color was found to be directly proportional to the amount of Fe(II) in the aqueous sample. The minimal sensor response with naked eye was found for 50 ng mL{sup −1} of Fe in 15 min of interaction. However, as low as 20 ng mL{sup −1} Fe could be quantified using a spectrophotometer. The detection limit calculated using the 3s/S criteria, where ‘s’ is the standard deviation of the absorbance of blank reagent loaded strip and ‘S’ is the slope of the linear calibration plot, was 1.0 ng mL{sup −1}. The strip was applied to measure Fe in a variety of samples such as ground water and fruit juices.

    A comic strip about a plane mirror was used in a high school optics test, and it was perceived that a large portion of the students believed that the mirror should be larger than the object so the virtual image could be entirely visible. Inspired on the comic strip, an experimental demonstration with flat mirrors was developed, in order to readdress this topic learning. Students were encouraged to create their own investigation of the phenomenon with a simple instrumental apparatus and also suggest different experimental approaches.

    Reed, H. L.; Nayfeh, A. H.

    1981-01-01

    This paper addresses the stability of two-dimensional, incompressible boundary-layer flow over plates with suction through porous strips. The mean flow is calculated using linearized triple-deck, closed-form solutions. The stability results of the triple-deck theory are shown to be in good agreement with those of the interacting boundary layers. Then different configurations of number, spacing, and mass flow rate through such porous strips are analyzed and compared with nonsimilar uniform-suction stability results from the point of view of applicability to laminar flow control.

  16. The Las Vegas Strip as a Genuinely Invented Global Landscape

    Directory of Open Access Journals (Sweden)

    Daniel Ortega

    2004-12-01

    Full Text Available Las Vegas, Nevada, is typically recognised as a place via a single urban gesture, that gesture being Las Vegas Boulevard, which is more commonly referred to as "The Strip". In constructing a thesis around the theme, "Here or There? Interconnections between the Global and the Local", one cannot ignore the invitation to discuss globalisation and its effects on a particular local fabric. For the purpose of this text, globalisation can be thought of as what Carmona et al describe as an intricate series of events leading to the world "becoming increasingly interconnected, with centralised decision making exploiting economies of scale and standardisation" (2003: 101. The centralised decision-making process for The Strip is evident in the strategy to develop individually themed casino resorts along Las Vegas Boulevard that respond to a competitive economy, thus creating a newly standardised landscape. If we also understand that globalisation can be thought of as the development of an interconnected world where economic, political and cultural boundaries can be easily crossed, this work can begin to define how the Las Vegas Strip is a genuinely invented global landscape. This paper addresses the "here-ness" as well as the "there-ness" of The Strip, while offering a dialectical framework for establishing a meaning of place by having 'there' placed 'here'. By employing semiological interpretations of real landscapes from around the globe (for example, Venturi et al, 1972, The Strip becomes a newly invented landscape of "simulations" (Baudrillard, 1988. As such, The Strip acts as a narrative that forms a unique place, opening the door to questions of authenticity and identity. This paper concludes by focusing on the question of "Here or There?" as an appropriate deviation from the assumed role that the post-modern landscape of the Las Vegas Strip plays. This work is intended to be a point of departure from the frequent criticism of the Las Vegas Strip as

    2015-01-01

    Full Text Available The aim of the present study was to examine the phenomenological qualities of self-reported negative and positive memories. The study was conducted in the Gaza Strip, Palestine, and a total of 134 autobiographical memories about negative and positive events were analyzed using a version of the Phenomenological Questionnaire for Autobiographical Memory (Manzanero & López, 2007. Participants were university students, 80 percent were women and 20 percent were men. Results showed that negative memories are more confused, more complex, and decay more over time than positive ones. In contrast, no differences were found between positive and negative memories on sensory information, spatial location, vividness, definition, accessibility, fragmentation, recall perspective, doubts about the accuracy of the memory, and how much participants recovered and talked about the event. High Dimensional Visualization (HDV graph revealed that there were individual differences between negative and positive memories but no consistent differences across participants.

  2. Visual method for detecting critical damage in railway contact strips

    2018-05-01

    Ensuring an uninterrupted supply of power in the electric traction is vital for the safety of this important transport system. For this purpose, monitoring and diagnostics of the technical condition of the vehicle’s power supply elements are becoming increasingly common. This paper presents a new visual method for detecting contact strip damage, based on measurement and analysis of the movement of the overhead contact line (OCL) wire. A measurement system configuration with a 2D camera was proposed. The experimental method has shown that contact strips damage can be detected by transverse displacement signal analysis. It has been proven that the velocity signal numerically established on that basis has a comparable level in the case of identical damage, regardless of its location on the surface of the contact strip. The proposed method belongs to the group of contact-less measurements, so it does not require interference with the structure of the catenary network nor the mounting of sensors in its vicinity. Measurement of displacements of the contact wire in 2D space makes it possible to combine the functions of existing diagnostic stands assessing the correctness of the mean contact force control adjustment of the current collector with the elements of the contact strip diagnostics, which involves detecting their damage which may result in overhead contact line rupture.

    Floating strip Micromegas are high-accuracy and discharge insensitive gaseous detectors, able to track single particles at fluxes of 7 MHz/cm{sup 2} with 100 μm resolution. We developed low-material-budget detectors with one-dimensional strip readout, suitable for tracking at highest particle rates as encountered in medical ion transmission radiography or inner tracker applications. Recently we additionally developed Kapton-based floating strip Micromegas with two-dimensional strip readout, featuring an overall thickness of 0.011 X{sub 0}. These detectors were tested in high-rate proton and carbon-ion beams at the tandem accelerator in Garching and the Heidelberg Ion-Beam Therapy Center, operated with an optimized Ne:CF{sub 4} gas mixture. By coupling the Micromegas detectors to a new scintillator based range detector, ion transmission radiographies of PMMA and tissue-equivalent phantoms were acquired. The range detector with 18 layers is read out via wavelength shifting fibers, coupled to a multi-anode photomultiplier. We present the performance of the Micromegas detectors with respect to timing and single plane track reconstruction using the μTPC method. We discuss the range resolution of the scintillator range telescope and present the image reconstruction capabilities of the combined system.

    Here, we report a simple and ultrasensitive upconversion fluorescent strip sensor based on NaYF4:Yb,Er nanoparticles (NPs) and the lateral flow immunochromatographic assay (LFIA). Carboxyl-modified β-NaYF4:Yb,Er NPs were successfully synthesized by a facile one-pot solvothermal approach, upon further coupling with monoclonal antibody, the resultant UCNPs-antibody conjugates probes were used in LFIA and served as signal vehicles for the fluorescent reporters. V. anguillarum was used as a model analyte to demonstrate the use of this strip sensor. The limit of the detection for the fluorescent strip was determined as 102 CFU mL-1, which is 100 times lower than those displayed by enzyme-linked immunosorbent assays, while the time needed for the detection was only 15 min. Furthermore, no cross-reaction with other eight pathogens was found, indicating the good specificity of the strip. This developed LFIA would offer the potential as a useful tool for the quantification of pathogens analysis in the future.

    Full Text Available Research on healthy behaviour such as physical activity and healthy nutrition and their combination is lacking among university students in Arab countries. The current survey assessed healthy nutrition, and moderate/vigorous physical activity (PA of 6266 students in Egypt, Libya, and Palestine. We computed a nutrition guideline achievement index using WHO recommendation, as well as the achievement of PA recommendations using guidelines for adults of the American Heart Association guidelines. Latent class regression analysis identified homogenous groups of male and female students, based on their achievements of both guidelines. We examined associations between group membership and achievement of guidelines. A three-class solution model best fitted the data, generating three student Groups: “Healthy Eaters” (7.7% of females, 10.8% of males, “Physically Active” (21.7% of females, 25.8% of males, and “Low Healthy Behaviour” (70.6% of females, 63.4% of males. We did not observe a latent class that exhibited combined healthy behaviours (physically active and healthy eaters, and there were no major differences between countries. We observed a very low rate of healthy nutrition (≈10% of students achieved greater than four of the eight nutrition guidelines, with little gender differences across the countries. About 18–47% of students achieved the PA guidelines, depending on country and gender, more often among males. Few females achieved the PA guidelines, particularly in Libya and Palestine. Culturally adapted multi-behavioural interventions need to encourage healthy lifestyles, nutrition and PA behaviours. National policies need to promote active living while addressing cultural, geographic, and other barriers to young adults’ engagement in PA.

  15. Pros and cons of flowers strips for farmers. A review

    Uyttenbroeck, R.

    2016-01-01

    Full Text Available Description of the subject. To counteract environmental problems due to agricultural intensification, European farmers can apply agri-environmental schemes in their fields. Flower strips are one example of these schemes, with the aim of supporting biodiversity, leading to an increase in "useful" species groups such as pollinators for crop pollination and natural enemies for pest control. However, to our knowledge, a complete appraisal of the pros and cons of flower strips, from a farmer's point of view, does not yet exist. It is proposed that better and more complete information could increase the adoption and implementation of such agri-environmental schemes. Objectives. This study aims 1 to assess the pros and cons of flower strips, from a farmer's point of view, and 2 to highlight the knowledge gaps that exist in the scientific literature, for the different types of pros and cons. Method. We listed the different components of the appraisal of pros and cons and conducted a systematic screening of the scientific literature on flower strips and these components. Results. The largest part of the 31 selected studies was concerning agronomical and ecological processes, such as pollination and animal pest control. Most of them indicated positive effects of flower strips. For many components of the appraisal, mostly economic and social ones, few or no studies were found. Conclusions. While a positive balance of pros and cons, from a farmer's point of view, came from our literature screening, large research gaps still remain and more research is required, especially in the economic and social components of the evaluation.

    The objective of this study was to determine whether humans could detect long-chain fatty acids when these lipid molecules are delivered to the oral cavity by edible taste strips. For suprathreshold studies, up to 1.7 umoles of stearic acid or linoleic acid were incorporated into 0.03 mm thick, one-inch square taste strips. Normalized taste intensity values for stearic acid were in the barely detectable range, with values equal to, or slightly above control strips. One-third of test subjects described the taste quality as oily/fatty/waxy. Approximately 75% of test subjects could detect the presence of linoleic acid when this fatty acid was incorporated into dissolvable strips. Normalized taste intensity values for linoleic acid were in the weak to moderate range. The most commonly reported taste quality responses for linoleic acid were fatty/oily/waxy, or bitter. When nasal airflow was obstructed, the perceived taste intensity of linoleic acid decreased by approximately 40 percent. Taste intensity values and taste quality responses for linoleic acid were then compared among tasters and non-tasters of 6-n-propylthiouracil (PROP). Individuals who could detect the bitter taste of PROP reported higher taste intensity values for linoleic acid compared with PROP non-tasters. However, taste quality responses for linoleic acid were similar among both PROP tasters and PROP non-tasters. These results indicate that humans can detect long-chain fatty acids by both olfactory and non-olfactory pathways when these hydrophobic molecules are delivered to the oral cavity by means of edible taste strips. These studies further show that genetic variation in taste sensitivity to PROP affects chemosensory responses to the cis-unsaturated fatty acid linoleic acid in the oral cavity. PMID:22521910

    Blood glucose levels were estimated in 101 neonatal blood samples using three glucose test strip methods and the results compared with those from a laboratory. BM-test-glycemie 20-800 test strips and Reflotest-hypoglycemie test strips gave a rapid and reliable estimate of blood glucose level in the range 0-8 mmol/l (0-140 mg/100 ml). Dextrostix test strips tended to overestimate all blood glucose levels.

    Lab scale experiments were undertaken to investigate air stripping as method for removing ammonia from cattle effluents and, more concretely, from the liquid fraction of swine manure. The effects of packet size, influent pH, air to liquid flow ratio and liquid recirculation flow in the stripping tower were investigated. The high ammonia removal efficiency of the air stripping method indicates that it could provide an interim solution for current waste management problems in the swine industry. (Author) 5 refs.

  7. The new silicon strip detectors for the CMS tracker upgrade

    International Nuclear Information System (INIS)

    Dragicevic, M.

    2010-01-01

    The first introductory part of the thesis describes the concept of the CMS experiment. The tasks of the various detector systems and their technical implementations in CMS are explained. To facilitate the understanding of the basic principles of silicon strip sensors, the subsequent chapter discusses the fundamentals in semiconductor technology, with particular emphasis on silicon. The necessary process steps to manufacture strip sensors in a so-called planar process are described in detail. Furthermore, the effects of irradiation on silicon strip sensors are discussed. To conclude the introductory part of the thesis, the design of the silicon strip sensors of the CMS Tracker are described in detail. The choice of the substrate material and the complex geometry of the sensors are reviewed and the quality assurance procedures for the production of the sensors are presented. Furthermore the design of the detector modules are described. The main part of this thesis starts with a discussion on the demands on the tracker caused by the increase in luminosity which is proposed as an upgrade to the LHC accelerator (sLHC). This chapter motivates the work I have conducted and clarifies why the solutions proposed by myself are important contributions to the upgrade of the CMS tracker. The following chapters present the concepts that are necessary to operate the silicon strip sensors at sLHC luminosities and additional improvements to the construction and quality assurance of the sensors and the detector modules. The most important concepts and works presented in chapters 7 to 9 are: Development of a software framework to enable the flexible and quick design of test structures and sensors. Selecting a suitable sensor material which is sufficiently radiation hard. Design, implementation and production of a standard set of test structures to enable the quality assurance of such sensors and any future developments. Electrical characterisation of the test structures and analysis

  8. Slip Morphology of Elastic Strips on Frictional Rigid Substrates.

    The morphology of an elastic strip subject to vertical compressive stress on a frictional rigid substrate is investigated by a combination of theory and experiment. We find a rich variety of morphologies, which-when the bending elasticity dominates over the effect of gravity-are classified into three distinct types of states: pinned, partially slipped, and completely slipped, depending on the magnitude of the vertical strain and the coefficient of static friction. We develop a theory of elastica under mixed clamped-hinged boundary conditions combined with the Coulomb-Amontons friction law and find excellent quantitative agreement with simulations and controlled physical experiments. We also discuss the effect of gravity in order to bridge the difference in the qualitative behaviors of stiff strips and flexible strings or ropes. Our study thus complements recent work on elastic rope coiling and takes a significant step towards establishing a unified understanding of how a thin elastic object interacts vertically with a solid surface.

  9. Feature curve extraction from point clouds via developable strip intersection

    Directory of Open Access Journals (Sweden)

    Kai Wah Lee

    2016-04-01

    Full Text Available In this paper, we study the problem of computing smooth feature curves from CAD type point clouds models. The proposed method reconstructs feature curves from the intersections of developable strip pairs which approximate the regions along both sides of the features. The generation of developable surfaces is based on a linear approximation of the given point cloud through a variational shape approximation approach. A line segment sequencing algorithm is proposed for collecting feature line segments into different feature sequences as well as sequential groups of data points. A developable surface approximation procedure is employed to refine incident approximation planes of data points into developable strips. Some experimental results are included to demonstrate the performance of the proposed method.

    2005-01-01

    Air-cooled heat sinks are employed in many electronic cooling applications since they provide significant heat transfer enhancement and operational flexibility. Strip-shaped fin heat sink is of interest and needs to be investigated as general cooling products for more applicability. The purposes of this study are to evaluate heat sink performance without bypass flow condition and to determine optimal heat sink geometries. The results show that the decreasing rate of thermal resistance of a heat sink decreases with increasing inlet air velocity, and the increasing rate of pressure drop increases with increasing inlet air velocity, but is not affected by input power. The increasing rate of optimal longitudinal fin spacing is larger than that of transverse fin spacing. The strip fin heat sink tested in this study showed better cooling performance compared to that of other plate fin type

    The CMS Silicon Strip Tracker (SST), consisting of more than 10 million channels, is organized in about 15,000 detector modules and it is the largest silicon strip tracker ever built for high energy physics experiments. The Data Quality Monitoring system for the Tracker has been developed within the CMS Software framework. More than 100,000 monitorable quantities need to be managed by the DQM system that organizes them in a hierarchical structure reflecting the detector arrangement in subcomponents and the various levels of data processing. Monitorable quantities computed at the level of individual detectors are processed to extract automatic quality checks and summary results that can be visualized with specialized graphical user interfaces. In view of the great complexity of the CMS Tracker detector the standard visualization tools based on histograms have been complemented with 2 and 3 dimensional graphical images of the subdetector that can show the whole detector down to single channel resolution. The fu...

  12. Silicon strip detectors for the ATLAS HL-LHC upgrade

    CERN Document Server

    Gonzalez Sevilla, S; The ATLAS collaboration

    2011-01-01

    The LHC upgrade is foreseen to increase the ATLAS design luminosity by a factor ten, implying the need to build a new tracker suited to the harsh HL-LHC conditions in terms of particle rates and radiation doses. In order to cope with the increase in pile-up backgrounds at the higher luminosity, an all silicon detector is being designed. To successfully face the increased radiation dose, a new generation of extremely radiation hard silicon detectors is being designed. We give an overview of the ATLAS tracker upgrade project, in particular focusing on the crucial innermost silicon strip layers. Results from a wide range of irradiated silicon detectors for the strip region of the future ATLAS tracker are presented. Layout concepts for lightweight yet mechanically very rigid detector modules with high service integration are shown.

  13. A new semicustom integrated bipolar amplifier for silicon strip detectors

    International Nuclear Information System (INIS)

    Zimmerman, T.

    1989-01-01

    The QPA02 is a four channel DC coupled two stage transimpedance amplifier designed at Fermilab on a semicustom linear array (Quickchip 2S) manufactured by Tektronix. The chip was developed as a silicon strip amplifier but may have other applications as well. Each channel consists of a preamplifier and a second stage amplifier/sharper with differential output which can directly drive a transmission line (90 to 140 ohms). External bypass capacitors are the only discrete components required. QPA02 has been tested and demonstrated to be an effective silicon strip amplifier. Other applications may exist which can use this amplifier or a modified version of this amplifier. For example, another design is now in progress for a wire chamber amplifier, QPA03, to be reported later. Only a relatively small effort was required to modify the design and layout for this application. 11 figs

    2017-12-01

    This study proposes a technique to straighten bent metallic strips with magnetic-force-assisted laser irradiation. Experiments were conducted for three different types of mechanically-bent mild strips. The first type was bent strips without any heat treatment. The second type was stress-relieved and third type was subcritical-annealed bent strips. These strips were straightened following different schemes of laser irradiation sequence to understand the performance of straightening. A parametric study was conducted by varying laser power and scanning speed. Micro-hardness, tensile test, Charpy impact test and microstructure after straightening were also studied. Different scanning schemes provided different microstructures and mechanical properties. Any serious deterioration in the quality of straightened strips was not noticed. Overall, subcritical-annealed bent strips provided the best performance in straightening. The proposed straightening scheme has potential of becoming an industrial practice.

  15. The Theoretical Instability Strip of V777 Her White Dwarfs

    Science.gov (United States)

    Van Grootel, V.; Fontaine, G.; Brassard, P.; Dupret, M.-A.

    2017-03-01

    We present a new theoretical investigation of the instability strip of V777 Her (DBV) white dwarfs. We apply a time-dependent convection (TDC) treatment to cooling models of DB and DBA white dwarfs. Using the spectroscopic calibration for the convective efficiency, ML2/α=1.25, we find a wide strip covering the range of effective temperature from 30,000 K down to about 22,000 K at log g = 8.0. This accounts very well for the empirical instability strip derived from a new accurate and homogenous spectroscopic analysis of known pulsators. Our approach leads to an exact description of the blue edge and to a correct understanding of the onset and development of pulsational instabilities, similarly to our results of TDC applied to ZZ Ceti white dwarfs in the recent past. We propose that, contrarily to what is generally believed, there is practically no fuzziness on the boundaries of the V777 Her instability strip due to traces of hydrogen in the atmospheres of some of these helium-dominated-atmosphere stars. Contrary to the blue edge, the red edge provided by TDC computations is far too cool compared to the empirical one. A similar situation was observed for the ZZ Ceti stars as well. We hence test the energy leakage argument (i.e., the red edge occurs when the thermal timescale in the driving region becomes equal to the critical period beyond which gravity modes cease to exist), which was successful to correctly reproduce the red edge of ZZ Ceti white dwarfs. Based on this argument, the red edge is qualitatively well reproduced as indicated above. However, upon close inspection, it may be about 1000 K too cool compared to the empirical one, although the latter relies on a few objects only. We also test the hypothesis of including turbulent pressure in our TDC computations in order to provide an alternate physical mechanism to account for the red edge. First promising results are presented.

    Damages to MSGCs (Micro-Strips Gas Chambers) induced by discharges have been investigated. Optimization of electrode shapes and/or deposition of a protective coating allows the potential difference between anode and cathode, thus increasing the gain. For prototypes of MSGCs made at the Centre de Recherches Nucleaires, each step of the manufacturing processes was carefully controlled. Results are presented on the influence of cleaning processes on the surface resistance of glass substrates. (author). 21 refs., 8 figs., 2 tabs
