Highlights: → The total neutron flux spectrum of the compact core of Ghana's miniature neutron source reactor was studied. → Using 20,484 energy grids, the thermal, slowing down and fast neutron energy regions were studied. - Abstract: The total neutron flux spectrum of the compact core of Ghana's miniature neutron source reactor was understudied using the Monte Carlo method. To create small energy groups, 20,484 energy grids were used for the three neutron energy regions: thermal, slowing down and fast. The moderator, the inner irradiation channels, the annulus beryllium reflector and the outer irradiation channels were the region monitored. The thermal neutrons recorded their highest flux in the inner irradiation channel with a peak flux of (1.2068 ± 0.0008) x 10 12 n/cm 2 s, followed by the outer irradiation channel with a peak flux of (7.9166 ± 0.0055) x 10 11 n/cm 2 s. The beryllium reflector recorded the lowest flux in the thermal region with a peak flux of (2.3288 ± 0.0004) x 10 11 n/cm 2 s. The peak values of the thermal energy range occurred in the energy range (1.8939-3.7880) x 10 -08 MeV. The inner channel again recorded the highest flux of (1.8745 ± 0.0306) x 10 09 n/cm 2 s at the lower energy end of the slowing down region between 8.2491 x 10 -01 MeV and 8.2680 x 10 -01 MeV, but was over taken by the moderator as the neutron energies increased to 2.0465 MeV. The outer irradiation channel recorded the lowest flux in this region. In the fast region, the core, where the moderator is found, the highest flux was recorded as expected, at a peak flux of (2.9110 ± 0.0198) x 10 08 n/cm 2 s at 6.961 MeV. The inner channel recorded the second highest while the outer channel and annulus beryllium recorded very low flux in this region. The flux values in this region reduce asymptotically to 20 MeV.

The effects of gamma and neutron irradiations on two different types of transistors, Junction Field Effect Transistor (JFET) and Bipolar Junction Transistor (BJT), were investigated. Irradiation was performed using a Syrian research reactor (RR) (Miniature Neutron Source Reactor (MNSR)) and a gamma source (Co-60 cell). For RR irradiation, MCNP code was used to calculate the absorbed dose received by the transistors. The experimental results showed an overall decrease in the gain factors of the transistors after irradiation, and the JFETs were more resistant to the effects of radiation than BJTs. The effect of RR irradiation was also greater than that of gamma source for the same dose, which could be because neutrons could cause more damage than gamma irradiation.

The MCNP-4C code was used to model the 3-D core configuration for the Syrian Miniature Neutron Source Reactor (MNSR). The continuous energy neutron cross sections were evaluated from ENDF/B-VI library to calculate the thermal and fast neutron fluxes in the MNSR inner and outer irradiation sites. The thermal fluxes in the MNSR inner irradiation sites were measured for the first time using the multiple foil activation method. Good agreements were noticed between the calculated and measured results. This model is used as well to calculate neutron flux spectrum in the reactor inner and outer irradiation sites and the reactor thermal power. Three 3-D neutronic models for the Syrian MNSR reactor using the MCNP-4C code were developed also to assess the possibility of fuel conversion from 89.87 % HEU fuel (UAl 4 -Al) to 19.75 % LEU fuel (UO 2 ). This model is used in this paper to calculate the following reactor core physics parameters: clean cold core excess reactivity, calibration of the control rod worth and calculation its shut down margin, calibration of the top beryllium shim plate reflector, axial neutron flux distributions in the inner and outer irradiation sites and the kinetics parameters ( ι p l and β e ff).

The prototype miniature neutron source reactor (MNSR) designed by China Institute of Atomic Energy has been operated successfully for more than 3 years and the practical experience enriches the original design idea. The commercial MNSR is under study design and develop in following aspects: 1. Prolonging the control rod cycle duration and core burn-up life; 2. Increasing the neutron flux per unit power. Obviously, the MNSR will show more advantages in extending application area and in providing the core using low envichment fuel. (Liu)

The uranium 235 is often used as a fuel to produce the energy in nuclear reactors. Uranium nuclei are fissioned with thermal neutrons and produce energy plus a number of neutrons. A fraction of such fission neutrons is involved in other fission with new nuclei to sustain the fission reactions. The remain fraction of the neutrons is lost from the reactor in two ways: escaped from the reactor, or absorbed with other nuclei that exist in the reactor before or produced from fission. Fission nuclei which absorb neutrons heavily are called p oison , such as Xe 135. Because Xe 135 absorbs neutrons heavily, it reduces the number of neutrons in the reactor. Hence, Xe 135 is studied explicitly in the MNSR reactor, and calculation of its negative reactivity is presented in this research during the operation, equilibrium, and after the shutting down of the reactor.

The analytical methods, step change in reactivity and ramp change in reactivity as well as numerical methods, fixed point iteration and Runge Kutta-gill were used to simulate the initial build up of neutrons in a miniature neutron source reactor with and without temperature feedback effect. The methods were modified to include photo neutron concentration. PARET 7.3 was used to simulate the transients behaviour of Ghana Research Reactor-1. The PARET code was capable of simulating the transients for 2.1 mk and 4 mk insertions of reactivity with peak powers of 49.87 kW and 92.34 kW, respectively. PARET code however failed to simulate 6.71 mk of reactivity which was predicted by Akaho et al through TEMPFED. (au)

Determining control rod characteristics is an essential problem of nuclear reactor analysis. In this research, the integral control rod worth of the miniature neutron source reactor MNSR is investigated. Some other parameters of the nuclear reactor, such as core excess reactivity, shut down margin, are also calculated. Group constants for all reactor components are generated by the WIMSD code and then are used in the CITATION code to solve the neutron diffusion equations. The maximum relative error of the calculated results compared with the measurement data is about 3.5%. (author)

A permanent epithermal neutron irradiation facility was designed in the Syrian Miniature Neutron Source Reactor (MNSR) by using the cadmium (cylindrical vial 1.0 mm in thickness, 38.50 mm in diameter and 180 mm in length) as thermal neutron shielding material, for a permanent epithermal neutron activation analysis (ENAA). This site was designed by shielding the internal surface of the aluminum tube of the first outer irradiation site in the MNSR reactor. I was used the activation detectors 0.1143% Au-Al alloy foils with 0.1 mm thickness and 2.0 mm diameter for measurement the thermal neutron flux, epithermal and R c d=A b are/A c over ratio in the outer irradiation site. Distribution of the thermal neutron flux in the outer irradiation capsule has been found numerically using MCNP-4C code with and without cadmium shield, and experimentally by irradiating five copper wires using the outer irradiation capsule. Good agreements were obtained between the calculated and the measured results. (author)

As first step of a program to design a repetitive pulsed neutron generator for applications, two miniature plasma foci have been designed and constructed at the Chilean commission of nuclear energy. The devices operate at an energy level of the order of tens of joules (PF-50 J, 160 nF capacitor bank, 20-35 kV, 32-100 J, {approx} 150 ns time to peak current) and hundred of joules (PF-400 J, 880 nF, 20-35 kV, 176-539 J, {approx} 300 ns time to peak current). Neutron emission has been obtained in both devices operating in deuterium. A specific technique was necessary to develop in order to detect neutron pulsed of 10{sup 4} neutrons per shot. The maximum total neutron yield measured was of the order of 10{sup 6} and 10{sup 4} neutrons per shot in the PF-400 J and PF-50 J respectively. Axial and radial measurements of the neutron emission are presented and the anisotropy is evaluated in this work. The neutrons are measured by pairs of silver activation counters, {sup 3}He detectors and scintillator-photomultiplier detectors. (authors)

2005-05-01

The Xe-135 equilibrium reactivity was calculated previously using the WIMSD4 and CITATION codes to estimate the fission product poisoning factor in the Syrian Miniature Neutron Source Reactor (MNSR). The fission product poisoning factor was used to calculate the Xe-135 concentrations and reactivities during the reactor operation, at saturation, and after shutdown. The fission product poisoning factor is used in this study to calculate the Sm-149 concentrations and reactivities during the reactor operation, at saturation, and after shutdown. The results are compared with Xe-135 concentrations and reactivities which were calculated before. The Xe-135 concentration increases versus the reactor operation time and reaches 2.836*10 13 atoms/cm 3 after 6 hours, where the Sm-149 concentration reaches 0.745*10 12 atoms/cm 3 . The Xe-135 and Sm-149 reactivities reach -0.451 and -0.256*10 -3 mk respectively after 6 hours of the reactor operation time. It is found that the Xe-135 and Sm-149 reactivities do not reach the equilibrium reactivities during typical reactor daily operating time. The Xe-235 concentration and reactivity are increased and reach to maximum values after 30000 second from the reactor shut down. Its maximum reactivity is -0.903 mk. Hence, the Xe-235 generates -0.452 mk extra reactivity after the reactor shutdown. The Sm-149 concentration and reactivates are increased after the reactor shut down. The Sm-149 reactivity reaches -0.249*10 -2 mk after 100000 second from the reactor shut down, and the Sm-149 introduces -2.231*10 -3 mk extra reactivity after the reactor shut down. Finally, the amount of Sm-149 accumulated in the reactor core after 1, 2, 5, and 10 years of the reactor operation time are: 3.995*10 -3 , 7.694*10 -3 , 17.226*10 -3 , and 2.892*10 -2 grams respectively.

Several explanations for this neutron dose-rate effect have been proposed, but further investigation is necessary to determine the mechanisms involved. In all cell transformation studies to date the immortalized, aneuploid 10T1/2 cell-line has been used. These cells may be premalignant; thus their response characteristics and, in particular, the nature of the transformation event, might differ from that in a normal, fibroblast cell. One reason for the present study was to determine whether the low-dose-rate effect of fission neutrons could be demonstrated in normal cells. If so, a normal cell system, which would more closely resemble a normal in vivo system, could be used for mechanistic studies. We chose Syrian hamster embryo (SHE) fibroblasts which are normal, diploid cells with a limited life span in culture. Upon exposure to low doses of ionizing radiation, the fraction of the cells that are transformed can be identified in a standard 8--10 day colony assay by examining their clonal morphology. Transformed cells form colonies with a dense, criss-crossed or piled-up structure. A high percentage of the transformed colonies can be further propagated and will acquire additional neoplastic characteristics; i.e., anchorage independence, immortality, altered proteolytic activity, karyotype alterations, and finally, tumorigenicity.

The Chinese Miniature Neutron Source Reactor (MNSR) is a low power research reactor with maximum thermal neutron flux of 1 x 10 12 n.cm -2 .s -1 in one of its inner irradiation channels and thermal power of approximately 30kW. The MNSR is designed based on the Canadian SLOWPOKE reactor and is one of the smallest commercial research reactors presently available in the world. Its commercial versions currently in operation in China, Ghana, Iran, Nigeria, Pakistan and Syria, is considered as an excellent tool for Neutron Activation Analysis (NAA), training of Scientist, and Engineers in nuclear science and technology and small scale radioisotope production. The paper highlights the basic design and theory of the commercial MNSR, its safety features, applications and advantages over the Chinese Prototype. The experimental flux characteristics determined in this work and in similar studies by other authors reveal that the commercial MNSR has more flux stability, longer life span, higher negative temperature coefficient of reactivity and low under-moderation compared to its prototype in China. The result shows that the facility is safe for reactor physics experiments, teaching and training of students and also ideal for application of NAA for the determination of elemental composition of biological and environmental samples. It can also be a useful tool for geochemical and soil fertility mapping. (author)

The Syrian crisis is considered the 'world's single largest crisis for almost a quarter of a century that has the biggest refugee population from a single conflict in a generation' (UN High Commissioner for Refugees, 2016). The rapid adoption of Facebook among Syrians questions whether it helps in maintaining the social capital of a war-torn nation and a dispersed Syrian population worldwide. Data was collected by means of a Facebook survey from 964 Syrian users. Results indicated that Facebook enhanced social identity and social capital through facilitating communication, collaboration and resource sharing among dispersed Syrians inside and outside the country. However, the offline rift of the nation was extended to Facebook through promoting hate speech among opposed parties. Results of this study may advance the understanding of the role of Facebook on social capital in countries going through similar crisis situations.

Determine the impact of the Syrian crisis on the hospitalization of Syrians in a psychiatric setting. All Syrians admitted to a psychiatric hospital in Lebanon between the 1st of January 2009 and the 31st of December 2013 were included. Number of admissions, psychiatric disorders and demographic and clinical data relative to patients were compared between those admitted before and after the crisis. 44 patients were admitted before the crisis and 106 after it. The distribution of diagnosis varied significantly after the crisis (p = 0.056) with the majority of patients being admitted for schizophrenia (37.7 %). The prevalence of suicidal ideation was higher after the crisis (p = 0.03) but suicidal attempts, need for electroconvulsive therapy and length of hospitalization did not differ significantly between both groups. Clinicians should be aware of the possible burden of mental illness in Syrians after the beginning of the Syrian crisis.

Methods Review of secondary data from gray literature and reports focusing on the influx of Syrian refugees to Lebanon by visiting databases covering humanitarian response in complex emergencies. Limitations include obtaining majority of the data from gray literature and changing statistics due to the instability of the situation. Results The influx of Syrian refugees to Lebanon, an already weak and vulnerable state, has negatively impacted life in Lebanon on different levels including increasing demographics, regressing economy, exhausting social services, complicating politics, and decreasing security as well as worsened the life of displaced Syrians themselves. Conclusion Displaced Syrians and Lebanese people share aggravating hardships of a mutual and precarious crisis resulting from the Syrian influx to Lebanon. Although a lot of response has been initiated, both populations still lack much of their basic needs due to lack of funding and nonsustainable program initiatives. The two major recommendations for future interventions are to ensure continuous and effective monitoring and sustainability in order to alleviate current and future suffering in Lebanon.

Full Text Available This article touches upon geopolitical dimension of the Syrian conflict. The authors consider in details regional subdivision of Syria and relations of Syrian regions with border countries. The authors of the article conclude that Arab nationalism as the Syrian state ideology and positioning of Syria as the center of Arab world were indispensable taking into account multiconfessional nature of Syria. Authors study the geostrategical doctrine of Hafez Asad (1970-2000 aimed to restore the territorial integrity of Syria (return of the Golan heights and creation of Great Syria, bring to light reasons of the alliances of Syria with Soviet Union and Iran. The authors discover reasons of hostility toward Syria from such actors as United States, Saudi Arabia, Turkey. The hostile attitude of the US political elites toward the Syrian state can be explained by American intention to undermine strategic partnership between Syria and Iran. Enmity of Saudi hostility toward the Syrian regime began with the assassination of the Lebanese Prime Minister Rafic Hariri (2005. This action destroyed the political balance in Lebanon and was considered by the Saudis as a threat to their interests. Article contains analysis of the Syrian role in the Saudi-Iranian rivalry. To opinion of the authors, Turkish involvement in the Syrian conflict began with the attempts of the regime’s change in this country and evolved to the defense of Turkish national interests from the Kurdish factor. The authors make some conclusions about the role of US, Iran, Saudi Arabia, Turkey in the Syrian conflicts. In the article it’s made some forecasts about the development of Syrian conflict. The authors especially predict possibility of disintegration of the Syrian state according to spheres of influence of the external actors involved to this conflict with Mediterranean coast, Homs and Damascus under the control of government, northern regions of the country under Kurdish control, Raqqa

Full Text Available While the Syrian refugees crisis has increasingly continued its effect in both Turkey and other neighboring countries and European countries for more than five years, refugees do not adapt themselves to society in country of asylum, and are exposed to social exclusion. The purpose of the study is to explore social representations of social media users toward Syrian refugees in Turkey with a qualitative approach; because social representations may indicate the problems in the integration process of Syrian refugees and Turkish society, and the reasons of social exclusion toward Syrian refugees. Accordingly 98 entries, which were taken from frequently used social dictionaries in Turkey, were evaluated by researchers and seven thematic units were formed. Thematic units reflect (i perceived negative features of Syrian refugees, (ii perceived threats in Turkey due to Syrian refugees, (iii criticisms toward Syrian refugees policy of Turkish government, (iv positive attitudes toward Syrian refugees, (v perceived political importance of Syrian refugees, (vi proposed solutions toward perceived Syrian refugees problem, and (vii other criticisms toward Syrian refugees issue. Findings provide useful information which can be used to enable the social adaptation of Syrian refugees into Turkish society

Although Arabian horses have been bred in strains for centuries and pedigrees have been recorded in studbooks, to date, little is known about the genetic diversity within and between these strains. In this study, we tested if the three main strains of Syrian Arabian horses descend from three founders as suggested by the studbook. We examined 48 horses representing Saglawi (n = 18), Kahlawi (n = 16) and Hamdani (n = 14) strains using the Equine SNP70K BeadChip. For comparison, an additional 24 Arabian horses from the USA and three Przewalski's horses as an out group were added. Observed heterozygosis (H o ) ranged between 0.30 and 0.32, expected heterozygosity (H e ) between 0.30 and 0.31 and inbreeding coefficients (F is ) between -0.02 and -0.05, indicating high genetic diversity within Syrian strains. Likewise, the genetic differentiation between the three Syrian strains was very low (F st  horses. Among Arabian horses, we found three clusters containing either horses from the USA or horses from Syria or horses from Syria and the USA together. Individuals from the same Syrian Arabian horse strain were spread across different sub-clusters. When analyzing Syrian Arabian horses alone, the best population differentiation was found with three distinct clusters. In contrast to expectations from the studbook, these clusters did not coincide with strain affiliation. Although this finding supports the hypothesis of three founders, the genetic information is not consistent with the currently used strain designation system. The information can be used to reconsider the current breeding practice. Beyond that, Syrian Arabian horses are an important reservoir for genetic diversity. © 2017 Stichting International Foundation for Animal Genetics.

Polycapillary neutron lenses

The principle of multiple mirror reflection from smooth surfaces at small grazing angles enables the transport and guiding of high intensity slow neutron beams to locations of low background for neutron scattering and absorption experiments and to provide facilities for multiple instruments. Curved guides have been widely used at cold neutron facilities to remove the unwanted radiation (fast neutrons and gamma rays) from the beam without the use of filters. A typical guide has transverse dimensions of 50 mm and, with a radius of curvature of 1 km, transmits wavelengths longer than 5 A. Much tighter curves requires narrower transverse dimensions, otherwise there is little transmission. Typical neutron benders have a number of slots with transverse dimensions of ∼5 mm. Based on the same principle but using a different technology, recent developments in glass polycapillary fibers have produced miniature versions of neutron guides. Fibers with many thousands of channels having sizes of ∼ 10 μm enable beams of long wavelength neutrons (λ > 4 A) to be transmitted efficiently in a radius of curvature as small as a fraction of 1 m. A large collection of these miniature versions of neutron guides can be used to bend the neutron trajectories such that the incident beam can be focused. (author)

Syrian Issue in the Discourses of Political Leaders

2016-11-01

Full Text Available Syrian conflict as a part of social movements called as Arab Spring has been turned into a civil war. As a result of this Turkey has come to face with the biggest refugee crisis of its entire history. Thus political parties have used different discourses on Syrian conflict and refugee crisis according to new social, economical and political conditions. In this paper political discourses used by Turkish political leaders between 2011-2015 are examined in the context of their politics for Syrian conflict and refugees. The main goal of this work is to contribute to a better contemplation on the Syrian conflict and refugee crisis by ascertaining political parties’ approaches.

Full Text Available The remaining small Jewish communities of Syria run the risk of disappearing completely due to the marginalization suffered as a consequence of the political situation since 1948. The Eli Cohen affair (1965, the Six-­Day War (1967, and the Yom Kippur War (1973 made the Baathist authorities of the country consider definitively the Syrian Jews as suspected Zionists or Zionist sympathizers. Nevertheless, in Syrian popular perceptions, the view of the Jews and Judaism did not always coincide with the ideology and propaganda emanating from the regime. In fact it is very interesting to note how good memories of times past, about an erstwhile coexistence with members of the Jewish community, still survive among many Syrians, both Muslims and Christians, belonging to the so-­called “urban middle class.” This paper evaluates some examples, in the forms of anecdotes, popular sayings and proverbs, dealing with the Jews, and popularized in Syrian colloquialisms, in order to reveal some of the popular views of Judaism and Jews within Syrian society.

The Syrian Civil War started in March 2011 and it was seen as a result of Arab Spring, that noteworthy affects this region. But, although it had been a few years the Arab Spring hasn't come to Syria yet. While Syrian people,neighbor countries and the people in the region were all waiting for the spring to come, the rising of the Civil Wars and the affects of military, political and the economics sports of the countries that Syrian Regime politically, economically and commercially aligned with, had been turned into a humanitarian tragedy. As a result of the civil attacks of the Regime of Syrian to his people, around 300.000 people did,around 6.5 million people have been displaced, the numbers of the people need help increased to 10 million and so the number of the Syrian refugees in the neighbor countries reached to 3.795.284. As a result of this civil war in Syria 1.679.963 Syrian Arab Republic citizens have come to our country as refuges since 2011. The number of Syrian refugees reached 326 333 in Gaziantep Province.

A nationwide investigation of radon levels in Syrian houses was carried out during the period 1991-1993. Passive radon diffusion dosemeters using polycarbonate detectors were distributed in houses all over Syria. Detectors were subjected to electrochemical etching to reveal latent tracks of alpha particles. The mean radon concentration in Syrian houses was found to be 45 Bq m -3 with some values several times higher. This investigation indicated that there were a few houses in Syria that require remedial action. Most houses that have high levels of radon were found in the southern area, especially in the Damascus governorate. The study also indicated that radon concentrations were higher in old houses built from mud with no tiling. (author)

Introduction Many Syrians have left their country and migrated to other countries since March 2011, due to the civil war. As of March 2016, a total of 2,747,946 Syrian refugees had immigrated to Turkey. Some Syrian refugees have been living in camps, while 2,475,134 have been living in metropolitan areas, such as Ankara. Study Objective This study investigated Emergency Medical Service (EMS) utilization among Syrian refugees residing in Ankara. This study was a descriptive, cross-sectional database analysis using data obtained from the Department of EMS of the Ankara Provincial Health Directorate. Five stations in the Altındağ region of Ankara responded to 42% of all calls from Syrian refugees. Prehospital EMS in Ankara have been used mostly by Syrian refugees younger than 18-years-old. Study findings also suggest that medical staff in regions where Syrian refugees are likely to be treated should be supported and provided with the ability to overcome language barriers and cultural differences.

The mechanical properties of AISI 304 stainless steel irradiated for over a decade in the Experimental Breeder Reactor (EBR-II) were measured using miniature mechanical testing methods. The shear punch method was used to evaluate the shear strengths of the neutron-irradiated steel and a correlation factor was empirically determined to predict its tensile strength. The strength of the stainless steel slightly decreased with increasing irradiation temperature, and significantly increased with increasing dose until it saturated above approximately 5 dpa. An effective tensile strain hardening exponent was also obtained from the data which shows a relative decrease in ductility of steel with increased irradiation damage. Ferromagnetic measurements were used to observe and deduce the effects of the stress-induced austenite to martensite transformation as a result of shear punch testing.

The increasing flow of Syrian refugees to Turkey, coupled with their extended stay, highlights the need for culturally competent health care, which includes nursing interventions. The purpose of this study was to describe the experiences of nurses who provide care for Syrian refugees in internal medicine clinics in a hospital located in Turkey. This descriptive study was based on qualitative content analysis using an inductive approach and involved discovery and description of the data. The study sample consisted of 10 nurses who work at the internal medicine clinic of a State Hospital in Turkey. Data were collected using semistructured interviews. Three themes with related subthemes were derived from the data. Nurses who participated in the study experienced: (a) Nurses found communicating with Syrian refugees and their families difficult in the clinic. (b) Nurses observed and experienced differences and similarities in caring for Turkish and Syrian patients. (c) Nurses expressed and displayed compassion toward Syrian refugees during the caring process. In order for nurses to provide the best care for Syrian refugee patients, it is important to identify cultural caring behaviors observed by nurses in the promotion of culturally congruent nursing and health care.

This research examines photojournalist’ perspectives of Syrian refugees in Europe, encoding, and dissemination processes. It employs a qualitative approach and functionalism perspective of mass media by sending questionnaires to voluntary respondents. The findings show sharing similar background and/or having experiences in the Middle Eastern countries highly influence the perspective of photojournalists on Syrian refugees. The encoding process covers through research of priority issues, target audience, trustworthiness of photos, and audience interpretation. The distribution method includes taking advantages of personal social media to promote the links of photos. As part of mass media industry, photojournalists play a crucial role to contribute to social integration, particularly, in creating a shared understanding between European community and Syrian refugees. The current research serves as a basis to future investigations on the perspective of European community towards Syrian refugees, whether or not their perspective is influenced by such photos.

Full Text Available Background and Design: The frequency and variety of dermatological diseases significantly changed after 2011 in the regions where the Syrian refugees migrated because of the civil war in Syria where is bordered by our country. To reveal these changing, the demographic and dermatological data of the Syrian refugees were retrospectively examined in faculty of medicine, department of dermatology of our city where a significant amount of Syrian refugees have been living. Materials and Methods: A total of 326 refugees immigrated to our city and have been living in tent cities, and applied to our department between September 2012-July 2014 were included to our study. Age, gender, dermatological and laboratory findings were retrospectively examined. Skin diseases were examined in 16 groups according to the their frequency. The patients were divided into 4 age groups as 0-20, 21-40, 41-60 and, 61 and over; three most common diseases for each age group were analyzed. Results: Of 326 patients, 126 (38.7% were males, 200 (61.3% were females and the difference was significant in term of gender. The age range of the patients was 0 to 77 years, and the mean age was 21.6±10.5. The majority of patients were in 0-20 age group. Dermatological infectious diseases were the most frequent diseases group and cutaneous leishmaniasis was the most diagnosed dermatological disease among patients. Conclusion: Preventive health care services should be performed to prevent dermatological infectious diseases which are commonly seen in Syrian refugees, especially cutaneous leishmaniasis which is already endemic in our country, and limitations to reach physicians of these patients should be amended.

The effect of trade liberalisation on Syrian agriculture

Basel Abbas

2010-01-01

Full Text Available Syrian agricultural policy should be characterized by a high level of government intervention, including fixed prices, government monopoly in strategic crop marketing, government distribution of industrial fertilizers, significant barriers on food and agricultural commodities import and so on. Although there were certain changes and liberalization in this area during several last years, the Syrian agriculture remains as the most regulated sector of national economy in Near east and northern Africa.On the other hand, we may state the fact that Syrian governmental agriculture policy was successful considering so called strategic crops most of all in achieving self-sufficiency in wheat production, also an essential increase of cotton production volume which represents most important export crop of this near east country, took a part. Besides this progress there was restriction of disparity development in countryside and municipal household’s incomes, which is partial reason for slowing down of Syrian countryside poverty. These positive outcomes were reached at the expense of increasing go­vern­men­tal expenses and worsening of resources efficiency usage both in agriculture production and energy sectors. Considering forecasted spend of oil sources, the Syrian government will be ne­ce­s­sa­ri­ly forced to search for alternative resources of economic growth and government budget incomes in near future.The last five year country plan presumes consequental delimitation of grants and implication of value added tax. There is to be a quite large liberalisation in agriculture sector, which should lead to consequential down of wheat production, sugar beet and cotton and increase of barley, lentil and chickpea production.

Lebanon is the main hosting country for the Syrian crisis, with more than one million Syrian refugees. The objective of this study was to determine the prevalence of post-traumatic stress disorder (PTSD), and identify its possible predictors, in a sample of Syrian refugees living in camps in Lebanon. We conducted a household survey on Syrian refugees between 18 and 65years old in 6 camps of the Central Bekaa region, using the Mini International Neuropsychiatric Interview (M.I.N.I.) as a diagnostic tool. Among the 452 respondents, we found a lifetime prevalence of PTSD of 35.4%, and a point prevalence of 27.2%. The lifetime prevalence of SUD was 1.99% and the point prevalence 0.66%. Multivariate logistic regression could not identify any predictor of current PTSD among a list of demographic variables, but identified the Syrian hometown as a significant predictor of lifetime PTSD (p=.013), with refugees from Aleppo having significantly more PTSD than those coming from Homs (adjusted OR 2.14, 95% CI [1.28, 3.56], p=.004). PTSD was a real mental health issue in our sample of adult Syrian refugees in Central Bekaa camps, unlike SUD. Copyright © 2016 Elsevier Inc. All rights reserved.

Adversarial Framing: President Bashar al-Assad’s Depiction of the Armed Syrian Opposition

Full Text Available 'This paper evaluates how Syrian president Bashar al-Assad is framing his opponents in the context of the Syrian civil war. The question is addressed by conducting a qualitative thematic analysis of 13 interviews he gave to international television news networks and newspapers between March and November 2013. It is found that Al-Assad consequently labels the armed opposition as “terrorists” preponderantly composed of groups affiliated to Al-Qaeda. The “terrorists” are framed as posing a threat to the region as well as to international security on a global scale. Furthermore, Al-Assad denies the armed opposition its Syrian grassroots by portraying them as outside aggressors fighting for foreign interests. They are also depicted as “enemies of the Syrian people”, responsible for all the atrocities and human suffering committed during the Syrian civil war.' ' '

To the best of our knowledge, the mental health status of physically injured Syrian refugees has not yet been investigated. The aim of this study was to examine the prevalence of psychiatric morbidity among physically injured Syrian refugees in Turkey receiving treatment at the main rehabilitation centre near the Syrian border. This is a cross sectional study. Information was collected from consenting injured Syrian refugees at Dar-el-Shefa'a Hospital in Reyhanlı (Turkey) during a one week period in December 2012 and another one week period in August 2013. A clinical psychiatric interview was conducted to determine a diagnosis according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM) IV-TR. A total of 40 refugees consented and completed a clinical psychiatric interview. All refugees in this study did not have a significant past psychiatric history. The most prevalent current diagnosis was major depressive disorder (22.5%), adjustment disorder (20%), and post-traumatic stress disorder (15%). Five (12.5%) patients had no evidence of a psychiatric disorder. The prevalence of psychiatric morbidity among injured Syrian refugees in our study was extremely high. This may help guide the treatment and management of this select population. This study had a low number of participants. The method of assessment was not standardized with a validated tool. This study may help guide the treatment and management of this select population, both in neighbouring countries and as resettled refugees in Western host countries. Copyright © 2017 Elsevier Inc.

No study has investigated the availability and adherence of preventive oral care products on the Syrian market to evidence-based international recommendations. Data were collected in 2012, and updated in 2016, in terms of availability, characteristics and adherence to evidence-based international recommendations. Few preventive products adhered to the recommendations. Despite the large decrease in the number of oral care products on the Syrian market, due to the Syrian crisis, nonadherence of some of the available products is still present. A multisectorial approach at a policy level is needed to address such important limitations. The Syrian Ministry of Health should reform regulations for fluoride products to become subject to drug monitoring systems; the Syrian Arab Committee for Measurements and Standards needs to update its standards; and the Syrian General Dental Association should distribute a preventive booklet to dental practitioners.

This paper is based on a report commissioned by the United Nations High Commissioner for Refugees, which aims to provide information on cultural aspects of mental health and psychosocial wellbeing relevant to care and support for Syrians affected by the crisis. This paper aims to inform mental health and psychosocial support (MHPSS) staff of the mental health and psychosocial wellbeing issues facing Syrians who are internally displaced and Syrian refugees. We conducted a systematic literature search designed to capture clinical, social science and general literature examining the mental health of the Syrian population. The main medical, psychological and social sciences databases (e.g. Medline, PubMed, PsycInfo) were searched (until July 2015) in Arabic, English and French language sources. This search was supplemented with web-based searches in Arabic, English and French media, and in assessment reports and evaluations, by nongovernmental organisations, intergovernmental organisations and agencies of the United Nations. This search strategy should not be taken as a comprehensive review of all issues related to MHPSS of Syrians as some unpublished reports and evaluations were not reviewed. Conflict affected Syrians may experience a wide range of mental health problems including (1) exacerbations of pre-existing mental disorders; (2) new problems caused by conflict related violence, displacement and multiple losses; as well as (3) issues related to adaptation to the post-emergency context, for example living conditions in the countries of refuge. Some populations are particularly vulnerable such as men and women survivors of sexual or gender based violence, children who have experienced violence and exploitation and Syrians who are lesbian, gay, bisexual, transgender or intersex. Several factors influence access to MHPSS services including language barriers, stigma associated with seeking mental health care and the power dynamics of the helping relationship. Trust

A cross-sectional correlational study was conducted with a convenient sample of 550 Syrian refugees. Out of all the study participants, 88% reported seeking social support, 64.5% reported using avoidance, and 39.5% reported using problem solving. Participants who were male, single, and younger, and who had a higher education and a higher total income were satisfied with their income, were employed and free of chronic illnesses, and had higher problem-solving scores. Higher social support-seeking scores were associated with being female, older, and widowed; having a lower education and lower total income; being dissatisfied with their income; being nonemployed; and having chronic illnesses. A number of significant predictors were identified for each coping strategy. The results of this study could be used to formulate programs and develop services regarding the stressors encountered by Syrian refugees and their coping strategies.

2009-01-01

Presenting neutronic calculations pertaining to the Iranian miniature research reactor is the main goal of this article. This is a key to maintaining safe and reliable core operation. The following reactor core neutronic parameters were calculated: clean cold core excess reactivity (ρ ex ), control rod and shim worth, shut down margin (SDM), neutron flux distribution of the reactor core components, and reactivity feedback coefficients. Calculations for the fuel burnup and radionuclide inventory of the Iranian miniature neutron source reactor (MNSR), after 13 years of operational time, are carried out. Moreover, the amount of uranium burnup and produced plutonium, the concentrations and activities of the most important fission products, the actinide radionuclides accumulated, and the total radioactivity of the core are estimated. Flux distribution for both water and fuel temperature increases are calculated and changes of the central control rod position are investigated as well. Standard neutronic simulation codes WIMS-D4 and CITATION are employed for these studies. The input model was validated by the experimental data according to the final safety analysis report (FSAR) of the reactor. The total activity of the MNSR core is calculated including all radionuclides at the end of the core life and it is found to be equal to 1.3 x 10 3 Ci. Our investigation shows that the reactor is operating under safe and reliable conditions.

The neutrons generator becomes miniature; Le generateur de neutrons se miniaturise

Energy Technology Data Exchange (ETDEWEB)

Boulben, A

2005-05-01

A mini neutrons generator has been designed by researchers of the California university of Los Angeles which does not need any high voltage power supply ar any radioactive element. The system comprises a tubular vacuum chamber of few tenths of cm filled up with gaseous deuterium at very low pressure (0.7 Pa) and an erbium deuteride (ErD{sub 3}) screen. A lithium tantalate (LiTaO{sub 3}) pyroelectric crystal and a tungsten electrode are used to ionize and accelerate the gaseous deuterium with a minimum energy need. The collision of deuterium ions with the screen generates a maximum flow rate of about a thousand neutrons per second. Short paper. (J.S.)

Three innovative sub-miniature fission chambers (SMFC), designed and manufactured at the Nuclear Measurement Systems Laboratory (LSMN) of CEA/Cadarache, were extensively tested in the BR2 research reactor at SCK•CEN, Mol. We present the experimental results for the (thermal) neutron sensitivity, the gamma-induced signal, the signal due to activation, the current picked up by the signal cable, the global current/voltage characteristics and the long term behaviour up to a thermal neutron fluence of 2.7·1021 n/cm2. We also compare the data with results from calculations with our FCD computer code. The onset of the saturation domain is well predicted by FCD; the neutron sensitivities can be accounted for perfectly after a refinement of the FCD model.

Frantic Waiting: NGO Anti-Politics and "Timepass" for Young Syrian Refugees in Jordan

Directory of Open Access Journals (Sweden)

Ann-Christin Wagner

2017-12-01

Full Text Available Drawing on Sukarieh and Tannock's political economy of youth approach, this paper explores how Syrian refugee youth is constituted in protracted displacement in Jordan. It investigates a juvenile population often overlooked in Forced Migration Studies, disenfranchised rural Syrians, who fail to develop practices of youthfulness, yet in exile are subjected to alternative productions of youth by the aid sector. Depoliticized NGO youth programming overlooks Syrians' limited access to the labour market and higher education. While educational trainings aim to produce entrepreneurial and citizen refugees, they ultimately contribute to the creation of timepass and precarious lives. This research is grounded in fourteen months of ethnographic fieldwork with Syrian refugees in a border town in northern Jordan.

The aim of this study was to evaluate the demographic and clinical characteristics of Emergency Department (ED) visits made by Syrian refugees and to assess the cost of their healthcare. This retrospective study was conducted in adult Syrians who visited the ED of Adiyaman University Training and Research Hospital, Adiyaman Province, Turkey, between 01 January and 31 December 2015. We evaluated 10,529 Syrian refugees who visited the ED, of whom 9,842 were included in the study. The number of ED visits significantly increased in 2015 compared with 2010; the increase in the proportion of total ED visits was 8% (n = 11,275, dif: 8%, CI 95%: 7.9- 8.2, p refugees and the remaining 1.5% accounted for the visits made by other individuals. Upper respiratory tract infections (URTI) were the diseases most frequently presented (n = 4,656; 47.3%), and 68.5% of ED visits were inappropriate (n = 6,749). The median ED length of stay (LOS) of the Syrian refugees was significantly longer than that of the other individuals visiting the ED (p refugees who visited the ED was calculated as US$ 773,374.63. This study showed that Syrian refugees have increased the proportion of ED visits and the financial healthcare burden. The majority of ED visits made by Syrian refugees were inappropriate. In addition, their ED LOS was longer than that of other individuals making ED visits.

The Syrian conflict has displaced over 1.2 million Syrians into Lebanon. As a result of displacement, some Syrian families are turning to child marriage as a coping mechanism. The prevalence of early marriage has reportedly increased and the average age of marriage decreased during the crisis. The aim of the project was to understand the underlying factors contributing to child marriage among Syrian refugees in Lebanon using Cognitive Edge's SenseMaker®. This manuscript explores the process of implementing this novel research tool in a humanitarian setting. Twelve interviewers conducted SenseMaker® interviews with married and unmarried Syrian girls, Syrian parents, as well as married and unmarried men. Participants were asked to share a story about the lives of Syrian girls in Lebanon and to self-interpret the narratives by answering follow-up questions in relation to the story provided. Data collection occurred across three locations: Beirut, Beqaa, and Tripoli. In total 1422 narratives from 1346 unique participants were collected over 7 weeks. Data collection using SenseMaker® was efficient, capable of electronically capturing a large volume of quantitative and qualitative data. SenseMaker® limitations from a research perspective include lack of skip logic and inability to adjust font size on the iOS app. SenseMaker® was an efficient mixed methods data collection tool that was well received by participants in a refugee setting in Lebanon. The utility of SenseMaker® for research could be improved by adding skip logic and by being able to adjust font size on the iOS app.

2016-01-01

Since March 2011, an estimated 600,000 Syrian refugees crossed into Jordan, of which 52% were children. Demand for health care is overwhelming. The burden of heart disease in Syrian refugee children is not known. The aim of this study WAS to describe heart disease in Syrian refugee children in terms of diagnoses, presentation, outcome, and funding sources for treatment. From April 1, 2012 to April 30, 2014, data on Syrian refugee children who were referred to the Pediatric Cardiology Department at Jordan University Hospital and were found to have heart disease was recorded. In this study, we describe diagnoses, presentations, complications, and mortality. We discuss therapeutic procedures and their funding sources. Patients were followed until July 31, 2014. In all, 119 children, median age 2 years (6 days to 16 years), were diagnosed with heart disease. At presentation, 37% had failure to thrive, 13% had severe complications, and 32% of cyanotic patients had severe hypoxia with oxygen saturation of Syrian refugee children constitutes a major problem for both patients and health systems of host countries. Late presentation and diagnosis, high rate of complications, suboptimal living conditions, lack of funding, shortage of specialized centers and personnel, and high mortality rates are among the major challenges facing this patient population.

The Syrian conflict has displaced five million individuals outside their country with Lebanon hosting the largest numbers per capita. Around 24% of Syrian refugees fleeing to Lebanon are women of reproductive age (15-49). Yet, a better understanding of the sexual and reproductive health needs of Syrian refugee women in Lebanon is required to improve provided services. Eleven focus group discussions were conducted in four regions of Lebanon with 108 Syrian refugee women of reproductive age. Thematic analysis was used to examine the data. Interviewed women were mainly adults. They believed that, in Lebanon, they were subjected to early marriage compared to the norm in Syria due to their financial situation and uncertainty. Cost was reported as the main barrier to use contraception in Lebanon but some Syrian refugee women were not aware of free services covering sexual and reproductive health. In general, marriage, pregnancy, and family planning behavior of Syrian refugee women in Lebanon slightly differed from those in Syria pre-conflict in terms of age of marriage, conception subsequent to marriage, and contraception method. Hence, interventions to increase awareness of subsidized sexual and reproductive health services, including free contraceptives at primary health care centers, and those targeting protection from early marriage of Syrian refugee women in Lebanon are strongly recommended.

NORM waste management in the oil and gas industry. The Syrian experience

International Nuclear Information System (INIS)

Al-Masri, M.S.; Suman, H.

2003-01-01

Syrian experience with respect to naturally occurring radioactive materials (NORM) waste produced by the Syrian oil industry is described. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubings which are considered to contain the highest levels of radium isotopes ( 226 Ra, 228 Ra, 224 Ra); this type of waste being currently stored in standard barrels in a controlled area. Second, sludge wastes containing low levels of radium isotopes were found in large amounts in each Syrian oilfield; plastic lined disposal pits were constructed in each area for temporary storage. However, disposal criteria for the above two categories of NORM waste are still under discussions. Third, soil contaminated with NORM as a result of uncontrolled disposal of production water was also considered as NORM waste. The Syrian criteria for disposal and clean up of this type of waste has been defined and approved by the Regulatory Office. (author)

Ideological Tensions in the Ranks of Syrian Officers: the Trigger of Military Circles Transformation in the Country?

Directory of Open Access Journals (Sweden)

Jana Kostrounova

2012-06-01

Full Text Available Despite the research by some authors on the Syrian Arab Republic and its stand in the Middle East Region, little is known about the perspective of the Syrian military, unofficially called the “elder statesman”, who rules this country. The overall image that emerges not only from the Arab media during the revolutionary year 2011 is ambivalent: lazy, corrupt, unpatriotic, apathetic soldiers with poor fighting spirits versus the Free Syrian Army newly formed in July 2011. This paper recovers some perspectives of the Syrian revolt and tries to answer, whether or whether not is the newly based military opposition in the country a real threat to the Assad regime. An analysis of historical background, Syrian veterans, relation between the official political doctrine and Islam brings new perspectives and own explanations that could even challenge some of the widely held assumptions about the Syrian military: 1 There is and won’t be any “civil war” in the Syrian Arab Republic at all; this conflict should be viewed as Islamic fitna and its roots come from the 1970’s. It is a regime strongly connected to rife corruption at the top ranks, hurting the morale of the lower, but stronger Islamic ranks; 2 Doctrinal relations between the Syrian army and official religious authorities in the Muslim world have been always tense; and 3 The Syrian army would have found the necessity of its own, inner transformation despite of the so-called “Arab Spring 2011”. This paper suggests that the character of the Syrian national revolt may be intended to reflect a deeper ideological antagonism between the Sunni and Shia Islam.

An ultra miniature pinch-focus discharge

International Nuclear Information System (INIS)

Soto, L.; Pavez, C.; Moreno, J.; Pavez, C.; Barbaglia, M.; Clausse, A.

2004-01-01

As a way to investigate the minimum energy to produce a pinch plasma focus discharge, an ultra miniature device has been designed and constructed (nano focus NF: 5 nF, 5-10 kV, 5-10 kA, 60-250 mJ, 16 ns time to peak current). Sub-millimetric anode radius covered by a coaxial insulator were used for experiments in hydrogen. Evidence of pinch was observed in electrical signals in discharges operating at 60 mJ. A single-frame image converter camera (4 ns exposure) was used to obtain plasma images in the visible range. The dynamics observed from the photographs is consistent with: a) formation of a plasma sheath close to the insulator surface, b) fast axial motion of the plasma sheath, c) radial compression over the anode, and d) finally the plasma is detached from the anode in the axial direction. The total time since stage a) to d) was observed to be about 30 ns. X ray and neutron emission is being studied. Neutron yield of the order of 10 3 neutrons per shot is expected for discharges operating in deuterium at 10 kA. (authors)

The Perspective of Trabzon Public on the Syrians in the Scope of Temporary Protection

Mine GÖZÜBÜYÜK TAMER

2016-12-01

Full Text Available As a result of the crisis environment that started in Syria in March 2011 and the conflicts that have been going on until today, millions of Syrians have had to leave their countries in order to provide life and property security and to find better life opportunities. They have migrated towards foremost Turkey, Lebanon, Iraq, Jordan and European Union (EU countries. This movement of the Syrians towards other countries deeply affects many countries. Due to the fact that Turkey is a neighboring country, it is one of the countries most affected by this process. Besides its geographical proximity, the presence of religious, historical and cultural ties has also been instrumental in making this effect more noticeable. The aim of this study is to determine the issues about Syrians who fled from the ongoing civil war in Syria and took refuge in Turkey from the point of view of the public in Trabzon. For this purpose, firstly, Trabzon public opinion has been established on the basis of acceptance of the Syrians within the temporary protection to Turkey and the perspective on how to manage and what to do about the policies envisaged for the Syrians. Then the predictions about the permanence of the Syrians in Turkey were put forward and the view of the people of Trabzon on the long term was evaluated. However, in the case of Trabzon, it was tried to reveal the thoughts and expectatitions of the Syrian people under temporary protection of the Turkish society.

In this study, we aimed to compare the Syrian refugees and resident Turkish pregnant population in terms of Toxoplasma seroprevalence. Data acquired from Kahramanmaraş Necip Fazıl City Hospital Department of Obstetrics and Gynecology between 2012 and 2013 were analyzed retrospectively. Results of 7201 Toxoplasma IgM tests and 4113 Toxoplasma IgG tests were evaluated. For 2012 and 2013 Toxoplasma IgM seropositivity was found in Syrian refugees 4.76% and 4.84% respectively in our study. In the same population Toxoplasma IgG seropositivity rates were 80% and 62.6%, respectively. Toxoplasma IgM seropositivity rates for the native peoples in Turkey in 2012 and 2013 was 1.96% and 2.34%, while in the same population Toxoplasma IgG seropositivity was detected 49.7% and 45.7% respectively. Toxoplasma IgM seropositivity was statistically higher in Syrian refugees for each year (p Syrian refugees was statistically higher (p Syrian refugees living in the region of Kahramanmaraş were statistically higher than the rates of local inhabitants, we consider that this condition should be taken into account in the follow-ups of Syrian pregnant refugees outnumbering in Kahramanmaraş and its vicinity.

Violence Against Displaced Syrian Women in Lebanon.

Usta, Jinan; Masterson, Amelia Reese; Farver, JoAnn M

2016-10-01

This study used focus group discussions to explore 29 Syrian women's experiences of being displaced refugees in Lebanon. Women reported intimate partner violence (IPV), harassment, and community violence. They experienced difficult living conditions characterized by crowding and lack of privacy, adult unemployment, and overall feelings of helplessness. Most frequently, they used negative coping strategies, including justification and acceptance of IPV and often physically harmed their own children due to heightened stress. Some sought support from other Syrian refugee women. Although the study did not address the root causes of IPV, the results shed light on women's experiences and indicate that training them in positive coping strategies and establishing support groups would help them face IPV that occurs in refugee settings.

Benage, Matthew; Greenough, P Gregg; Vinck, Patrick; Omeira, Nada; Pham, Phuong

2015-01-01

After more than three years of violence in Syria, Lebanon hosts over one million Syrian refugees creating significant public health concerns. Antenatal care delivery to tens of thousands of pregnant Syrian refugee women is critical to preventing maternal and fetal mortality but is not well characterized given the multiple factors obtaining health data in a displaced population. This study describes antenatal care access, the scope of existing antenatal care, and antenatal and family planning behaviors and practice among pregnant Syrian refugees in various living conditions and multiple geographic areas of Lebanon. A field-based survey was conducted between July and October 2013 in 14 main geographic sites of refugee concentration. The assessment evaluated antenatal services among a non-randomized sample of 420 self-identified pregnant Syrian refugee women that included demographics, gestational age, living accommodation, antenatal care coverage, antenatal care content, antenatal health behaviors, antenatal health literacy, and family planning perception and practices. In total, 420 pregnant Syrian refugees living in Lebanon completed the survey. Of these, 82.9% (348) received some antenatal care. Of those with at least one antenatal visit, 222 (63.8%) received care attended by a skilled professional three or more times, 111 (31.9%) 1-2 times, and 15 (4.3%) had never received skilled antenatal care. We assessed antenatal care content defined by blood pressure measurement, and urine and blood sample analyses. Of those who had received any antenatal care, only 31.2% received all three interventions, 18.2% received two out of three, 32.1% received one out of three, and 18.5% received no interventions. Only (41.2%) had an adequate diet of vitamins, minerals, and folic acid. Access, content and health behaviors varied by gestational age, type of accommodation and location in Lebanon. Standards of antenatal care are not being met for pregnant Syrian refugee women in

The intrarenal distribution of 125I-albumin in the syrian hamster

International Nuclear Information System (INIS)

Moeller, P.

1977-01-01

The intrarenal distribution of radioiodinated human serum albumin ( 125 RISA) after intravenous injection was studied in Syrian hamsters by scintillation counting and frozen section autoradiogrpahy. After 15, 30, and 60 min the virtual plasma albumin space in the renal cortex of the hamster represented 6.49, 7.13, and 8.06% respectively of the kidney tissue volume. From the cortex to the renal papilla the albumin space increased to about 30% of the tissue volume. In comparison to this the albumin space in the renal cortex of the rat was about 20%, and in the renal papilla about 33% (11). Frozen section autoradiography indicated that the distribution of radioalbumin in the renal cortex if the Syrian hamster is limited mainly to the kidney vessels, being especially noticeable in the glomerular capillaries. Toward the papilla increasingly greater (mainly extratubular) activity could be observed not only intravascularly but also interstitially. In the cortex of the rat kidney, on the other hand, radioactive albumin was accumulated (probably by filtration and reabsorption) predominantly in the proximal tubular epithelium. Within 30 min the kidneys of the rat excreted more than 10 times as much 125 I than the hamster kidneys. These results (substantially less cortical accumulation and urinary excretion of radioalbumin in the Syrian hamster) indicate that, in contrast to the rat, obviously much less albumin is filtered (and then accumulated by proximal reabsorption) by the Syrian hamster glomeruli. This suggests that the Syrian hamster kidney is more suitable than the rat kidney for determining the interstitial, cortical, albumin space. (orig./AJ) [de

Using MCNP-4C code for design of the thermal neutron beam for neutron radiography at the MNSR

International Nuclear Information System (INIS)

Shaaban, I.

2009-11-01

Studies were carried out for determination of the parameters of a thermal neutron beam at the MNSR reactor (MNSR-30 kW) for neutron radiography in the vertical beam port by using the MCNP-4C (Monte Carlo Neutron - Photon transport). Thermal, epithermal and fast neutron energy ranges were selected as 10 keV respectively. To produce a good neutron beam in terms of intensity and quality, several materials Lead (Pb), Bismuth (Bi), Borated polyethelyene and Alumina Oxide (Al 2 O 3 ) were used as neutron and photon filters. Based on the current design, the L/D of the facility ranges between 125, 110 and 90. The thermal neutron flux at the beam exit is 1.436x10 5 n/cm2 .s ,1.843x10 5 n/cm2 .s and 2.845x10 5 n/cm2 .s respectively, middots with a Cd-ratio of ∼ 2.829, 2.766, 3.191 for the L/D = 125, 110, 90 respectively. The estimated values for gamma doses are 6.705x10 -2 Rem/h and 1.275x10 -1 Rem/h and 2.678x10 -1 Rem/ h with bismuth. The divergent angle of the collimator is 1.348 degree - 2.021 degree. Such neutron beams, if built into the Syrian MNSR reactor, could support the application of NRG in Syria. (author)

The Politics of Syrian Refugees in Turkey: A Question of Inclusion and Exclusion through Citizenship

2018-03-01

Full Text Available Turkey began to receive refugees from Syria in 2011 and has since become the country hosting the highest number of refugees, with more than 3.5 million Syrians and half a million people of other nationalities, mainly from Afghanistan, Iraq and Iran. An important turning point regarding the legal status of Syrian refugees has come with recent amendments to the Turkish citizenship law. Based on ongoing academic debates on integration and citizenship, this article will explore these two concepts in the case of Syrian refugees in Turkey. We will argue that the shift in the Turkish citizenship law is a direct outcome of recent migration flows. We further argue that the citizenship option is used both as a reward for skilled migrants with economic and cultural capital and as a tool to integrate the rest of the Syrians. It also reflects other social, political and demographic concerns of the Turkish government. Using our recent ethnographic study with Syrians and local populations in two main refugee hosting cities in Turkey, Istanbul and Gaziantep, we will locate the successes and weaknesses of this strategy by exemplifying the views of Syrian refugees on gaining Turkish citizenship and the reactions of Turkish nationals.

Full Text Available Assessment of bone mineral density (BMD using dual energy X-ray absorptiometry (DXA technique is considered as a standard technique for diagnosing osteopenia and osteoporosis and evaluating the severity of such diseases. Numerous studies have demonstrated the necessity to establish an ethnic-specific reference data for Bone mineral density measurements. Such data are lacking for the Syrian population. The objectives of this study are (1 to establish BMD reference values in a group of healthy Syrian women using DXA technique, (2 to compare with values from other populations, (3 to study the prevalence of osteopenia and osteoporosis in Syrian women using the manufacturer reference values. A total of 951 healthy Syrian women aged 20-79 years participated in this study. Weight, height, and BMI have been determined. BMD measurements were performed using Lunar Prodigy Advance System (GE. The data were compared with those from other populations. The results have demonstrated the expected decline in BMD with age after peaking at 30-39 years old group. The peak values of the lumbar spine and femur neck were 1.16 (0.12, and 0.95 (0.13 g/cm2, respectively. The results of the Syrian women were compared with those from other populations and the differences were presented. Osteopenia was diagnosed in 35.80% and 60.31% and osteoporosis in 6.23% and 2.72% in lumbar spine and femur neck, respectively, of women 50-59 years of age. These ratios increased to 36.84%, 68.42% and 23.68%, 13.10%, respectively, in the age group more than 59 years. BMD values of the Syrian women were determined for the first time. The results demonstrate the importance of establishing population-specific reference range for BMD values for an accurate assessment of Osteoporosis. High prevalence of osteopenia and osteoporosis was demonstrated in Syrian using the manufacturer reference values.

Full Text Available The media coverage of women migrations has played an important role in shaping public opinion and governmental policies. This article aims at exploring the media portrayals of Syrian Migrant Women in Turkey. For this purpose, the research data were collected from the three Turkish online newspaper websites, Hürriyet, Birgün and Sabah, each of which has different editorial policy in representing migration, during one year period. The findings of quantitative content analysis of the news stories regarding Syrian migrant women would provide an understanding of the gender dimension of migration in Turkey. It concludes that Syrian Migrant Women in Turkey generally are reported on crime news and are framed as victims or perpetrators. However, the newspapers rarely report their hard living conditions.

The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system. Changing lifestyles and aging populations are shifting the global disease burden towards increased non-infectious diseases including chronic conditions, co-morbidities, and injuries which are more complicated and costly to manage. The strain placed on health systems threatens the ability to ensure the health needs of both refugees and host country populations are adequately addressed. In light of the increasing challenges facing host governments and humanitarian actors to meet health needs of Syrian refugees and affected host communities, this study was undertaken to assess utilization of health services among Syrian refugees in non-camp settings. A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households. Differences in household characteristics by geographic region, facility type, and sector utilized were examined using chi-square and t-test methods. Care-seeking was high with 86.1 % of households reporting an adult sought medical care the last time it was needed. Approximately half (51.5 %) of services were sought from public sector facilities, 38.7 % in private facilities, and 9.8 % in charity/NGO facilities. Among adult care seekers, 87.4 % were prescribed medication during the most recent visit, 89.8 % of which obtained the medication. Overall, 51.8 % of households reported out-of-pocket expenditures for the consultation or medications at the most recent visit (mean US$39.9, median US$4.2). Despite high levels of care-seeking, cost was an important barrier to health service access for Syrian refugees in Jordan. The cessation of free access to health care since the time of the survey is likely to have worsened

Predicting the duration of the Syrian insurgency

Full Text Available While there were several relatively short uprisings in Northern Africa and the Middle East during the Arab Spring, the dispute between the rebels and government forces in Syria has evolved into a full-scale civil war. We try to predict the length of the Syrian insurgency with a three-stage technique. Using out-of-sample techniques, we first assess the predictive capacity of 69 explanatory variables for insurgency duration. After determining the model with the highest predictive power, we categorize Syria according to the variables in this final model. Based on in-sample approaches, we then predict the duration of the Syrian uprising for three different scenarios. The most realistic point prediction is 5.12 years from the insurgency’s start, which suggests an end date between the end of 2016 and early 2017.

Comparison of calculated integral values using measured and calculated neutron spectra for fusion neutronics analyses

1987-01-01

The kerma heat production density, tritum production density, and dose in a lithium-fluoride pile with a deuterium-tritum neutron source were calculated with a data processing code, UFO, from the pulse height distribution of a miniature NE213 neutron spectrometer, and compared with the values calculated with a Monte Carlo code, MORSE-CV. Both the UFO and MORSE-CV values agreed with the statistical error (less than 6%) of the MORSE-CV calculations, except for the outer-most point in the pile. The MORSE-CV values were slightly smaller than the UFO values for almost all cases, and this tendency increased with increasing distance from the neutron source

2017-09-01

Purpose The influx of Syrian refugees into Jordan and Lebanon over the last 5 years presents an immense burden to national health systems. This study was undertaken to assess utilization of maternal health services among Syrian refugees in both countries. Description A cross-sectional survey of Syrian refugees living in urban and rural (non-camp) settings was conducted using a two-stage cluster survey design with probability proportional to size sampling in 2014-2015. Eighty-six percent of surveyed households in Lebanon and 88% of surveyed households in Jordan included women with a live birth in the last year. Information from women in this sub-set of households was analyzed to understand antenatal and intrapartum health service utilization. Assessment A majority of respondents reported seeking antenatal care, 82% and 89% in Jordan and Lebanon, respectively. Women had an average of at least six antenatal care visits. Nearly all births (98% in Jordan and 94% in Lebanon) took place in a health facility. Cesarean rates were similar in both countries; approximately one-third of all births were cesarean deliveries. A substantial proportion of women incurred costs for intrapartum care; 33% of Syrian women in Jordan and 94% of Syrian women in Lebanon reported paying out of pocket for their deliveries. The proportion of women incurring costs for intrapartum care was higher in Jordan both countries for women with cesarean deliveries compared to those with vaginal deliveries; however, this difference was not statistically significant in either country (Jordan p-value = 0.203; Lebanon p-value = 0.099). Conclusion Syrian refugees living in Jordan and Lebanon had similar levels of utilization of maternal health services, despite different health systems and humanitarian assistance provisions. As expected, a substantial proportion of households incurred out-of-pocket costs for essential maternal and newborn health services, making cost a major factor in care

The influx of Syrian refugees into Jordan presents an immense burden to the Jordanian health system, particularly in treating chronic health conditions. This study was undertaken to assess utilization of health services for chronic health conditions among Syrian refugees in non-camp settings. A survey of Syrian refugees in Jordan was undertaken in June 2014 to characterize health seeking behaviors and issues related to accessing care for hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, and arthritis. A cluster design with probability proportional to size sampling was used to attain a nationally representative sample of 1550 non-camp Syrian refugee households. Of 1363 cases with a chronic health condition diagnosis, 84.7% had received care in Jordan. Public facilities faced a heavy burden serving over half (53.9%) of care-seekers; the remainder received care in the private (29.6%) and NGO/charity (16.6%) sectors. Individuals with non-communicable diseases (NCDs) in the central region of Jordan and with arthritis had the lowest rates of care-seeking when compared to other regions and conditions. Overall, 31.6% of care-seekers had an out-of-pocket payment for the most recent care-seeking event which averaged 18.8 USD (median = 0 USD), excluding cost of medications. Forced displacement presents major challenges to those with NCDs, which have the potential to seriously impact both the quality of life and life expectancy amongst refugees. NCD patterns among Syrian refugees indicate the importance of continuing support to public sector services in Jordan to adequately meet expanding needs and ensure appropriate prevention and control of priority NCDs.

Syrian Refugees, Health and Migration Legislation in Turkey.

Science.gov (United States)

Ekmekci, Perihan Elif

2017-12-01

This paper discusses the crucial effects of Turkish health and migration laws on Syrian refugees' access to public health services and social determinants of health. Key aspects of current Turkish laws affect the health of both refugees and Turkish citizens in many ways. The huge influx of refugees is increasing communicable disease risks, overcrowding hospitals, and more generally straining financial and health resources. Turkey's United Nations membership and its candidacy for European Union (EU) have led to increased alignment of Turkey's refugee and migration policies with international law. Major differences remain, however, and Turkey's remaining noncompliance with international refugee laws is a major force driving Syrian refugee's flight to EU countries, as refugees desperately seek the right to better health and social services.

A Content Analysis on the Representation of Syrian Asylum Seekers in the Turkish Press

Directory of Open Access Journals (Sweden)

Müzeyyen Pandır

2015-11-01

Full Text Available This article is a content analysis of the representation of Syrian asylum seekers in the Turkish press. The research sample includes news reports, columns and visuals published in 2014 in five national newspapers with the highest circulation figures (“Hürriyet”, “Sabah”, “Posta”, “Sözcü”, “Zaman”. The article is part of a larger research project, which is funded by TÜBİTAK, investigating the representation of Syrian asylum seekers between 2011 and 2015 in Turkish newspapers. Analysing news texts and columns is widely held in research projects. However, conducting a visual analysis on news photographs is usually overlooked. This study investigates news texts and news photographs together. The study shows that the coverage of Syrian asylum seekers has usually a positive or neutral content. However, the results also point out the ambivalence in the representations of asylum seekers. The representations of Syrian asylum seekers portray these individuals mostly as “poor” people “in need of help” as well as “threats” for social security. These frequently repeated representations and ambivalence show that the representation of Syrian asylum seekers in Turkish newspapers reproduces the stereotypical representation of asylum seekers as defined in international studies.

Since 2013, hundreds of thousands of refugees have migrated southward to Jordan to escape the Syrian civil war that began in mid-2011. Evaluating impacts of conflict and migration on land use and transboundary water resources in an active war zone remains a challenge. However, spatial and statistical analyses of satellite imagery for the recent period of Syrian refugee mass migration provide evidence of rapid changes in land use, water use, and water management in the Yarmouk-Jordan river watershed shared by Syria, Jordan, and Israel. Conflict and consequent migration caused ∼50% decreases in both irrigated agriculture in Syria and retention of winter rainfall in Syrian dams, which gave rise to unexpected additional stream flow to downstream Jordan during the refugee migration period. Comparing premigration and postmigration periods, Syrian abandonment of irrigated agriculture accounts for half of the stream flow increase, with the other half attributable to recovery from a severe drought. Despite this increase, the Yarmouk River flow into Jordan is still substantially below the volume that was expected by Jordan under the 1953, 1987, and 2001 bilateral agreements with Syria.

The Syrian War has created a mass exodus of Syrian citizens to neighboring countries and exposed them to many atrocities. We explored factors affecting well-being and posttraumatic growth (PTG) of refugees residing in Jordan. Participants (N = 250) were surveyed via nongovernmental organizations (NGOs). Outcome criteria included a global well-being rating and the Posttraumatic Growth Inventory. Trauma exposure assessment included The Harvard Trauma Questionnaire (HTQ) and The War Events Questionnaire. Ordinary least squares regression examined associations between potential contributors to refugee well-being and PTG, including work, age, sex, income, education, posttraumatic stress disorder (PTSD) severity, physical pain, health, NGO assistance, psychotic/affective mental disorder, and length of residence in Jordan. Mean participant score on the PTSD-HTQ scale was 2.37 (SD = 0.63; range: 1 [no symptoms] to 3.88 [extremely severe symptoms]). Additionally, 74.6% of participants received NGO assistance and 92.7% experienced war events. Univariate and multivariate results indicated enhancement of well-being was associated with income, r = .34, β = .26, p Syrian refugees' mental health.

Trafficking and Syrian Refugee Smuggling: Evidence from the Balkan Route

Danilo Mandic

2017-06-01

Full Text Available As of March 2016, 4.8 million Syrian refugees were scattered in two dozen countries by the civil war. Refugee smuggling has been a major catalyst of human trafficking in the Middle East and Europe migrant crises. Data on the extent to which smuggling devolved into trafficking in this refugee wave is, however, scarce. This article investigates how Syrian refugees interact with smugglers, shedding light on how human smuggling and human trafficking interrelated on the Balkan Route. I rely on original evidence from in-depth interviews (n = 123 and surveys (n = 100 with Syrian refugees in Jordan, Turkey, Greece, Serbia, and Germany; as well as ethnographic observations in thirty-five refugee camps or other sites in these countries. I argue that most smugglers functioned as guides, informants, and allies in understudied ways—thus refugee perceptions diverge dramatically from government policy assumptions. I conclude with a recommendation for a targeted advice policy that would acknowledge the reality of migrant-smuggler relations, and more effectively curb trafficking instead of endangering refugees.

The three-dimensional (3-D) detection of millimeter-scale ionization trails is of interest for detecting nuclear recoils in directional fast neutron detectors and in direction-sensitive searches for weakly interacting massive particles (WIMPs), which may constitute the Dark Matter of the universe. We report on performance characterization of a miniature gas target Time Projection Chamber (TPC) where the drift charge is avalanche-multiplied with Gas Electron Multipliers (GEMs) and detected with the ATLAS FE-I3 Pixel Application Specific Integrated Circuit (ASIC). We report on measurements of gain, gain resolution, point resolution, diffusion, angular resolution, and energy resolution with low-energy X-rays, cosmic rays, and alpha particles, using the gases Ar:CO{sub 2} (70:30) and He:CO{sub 2} (70:30) at atmospheric pressure. We discuss the implications for future, larger directional neutron and Dark Matter detectors. With an eye to designing and selecting components for these, we generalize our results into analytical expressions for detector performance whenever possible. We conclude by demonstrating the 3-D directional detection of a fast neutron source.

Full Text Available The conflict in Syria between the government of Bashar al-Assad and various other forces, which started in the spring of 2011, continues to cause displacement within the country and across the region. By the end of 2014, an estimated 7.6 million people were internally displaced and 3.7 million Syrians had fled the country since the conflict began (OCHA 2014; UNHCR 2015a. The refugee situation caused by the Syrian conflict is dire, and it has placed enormous strain on neighboring countries. Lebanon, Jordan, Iraq, Egypt, and Turkey host massive numbers of Syrian refugees, and Syrians have been seeking protection beyond these countries in increasing numbers since 2011.This paper looks at the burdens and costs of the Syrian refugee crisis and considers how they have, or have not, been shared by the international community at large, and in particular by Germany, Sweden, the United Kingdom, and the United States. It also considers to what degree Syrians have been able to find protection in states outside the region. Germany and Sweden, by the end of 2014, had provided protection to the largest number of Syrian refugees outside the region. Although Germany, Sweden, the United Kingdom, and the United States differ in the level of protection provided to Syrians, all four states have increased protection to Syrians via resettlement and asylum (and in the case of the US temporary protected status since 2012. Despite this, the degree of protection provided by the four states is modest in relation to that provided by neighboring countries to Syria, and far more could be done. This paper also argues that the international community as a whole has not sufficiently contributed toward alleviating the burden caused by the Syrian refugee influx, in terms of both financial assistance and refugee resettlement.The paper puts forward two general recommendations to reduce the strain on neighboring countries: increase the level of burden sharing by the international

DeLuca, P.M. Jr.

1988-01-01

The purpose was to investigate the radiological physics and biology of very low energy photons derived from a 1-GeV electron synchrotron storage ring. An extensive beam line and irradiation apparatus was designed, developed, and constructed. Dosimetry measurements required invention and testing of a miniature absolute calorimeter and a cell irradiation fixture suitable for scanning exposures under computer control. Measurements of the kerma factors of oxygen, aluminum and silicon for 14-20 MeV neutrons. Custom designed miniature proportional counters of cylindrical symmetry were employed in these determinations. The oxygen kerma factor was found significantly lower than values calculated from microscopic cross sections. We also tested Mg and Fe walled conventional spherical counters. The direct neutron-counting gas interaction is significant enough for these counters that a correction is needed. We also investigated the application of Nuclear Magnetic Resonance spectroscopy to radiation dosimetry. Our purpose was to take advantage of recent development of very high-field magnets, complex RF-pulse techniques for solvent suppression, and improved spectral analysis techniques

Metabolic influences on circadian rhythmicity in Siberian and Syrian hamsters exposed to long photoperiods.

Challet, E; Kolker, D E; Turek, F W

Calorie restriction and other situations of reduced glucose availability in rodents alter the entraining effects of light on the circadian pacemaker located in the suprachiasmatic nuclei. Siberian and Syrian hamsters are photoperiodic species that are sexually active when exposed to long summer-like photoperiods, while both species show opposite changes in body mass when transferred from long to short or short to long days. Because metabolic cues may fine tune the photoperiodic responses via the suprachiasmatic nuclei, we tested whether timed calorie restriction can alter the photic synchronization of the light-entrainable pacemaker in these two hamster species exposed to long photoperiods. Siberian and Syrian hamsters were exposed to 16 h:8 h light:dark cycles and received daily hypocaloric (75% of daily food intake) or normocaloric diet (100% of daily food intake) 4 h after light onset. Four weeks later, hamsters were transferred to constant darkness and fed ad libitum. The onset of the nocturnal pattern of locomotor activity was phase advanced by 1.5 h in calorie-restricted Siberian hamsters, but not in Syrian hamsters. The lack of phase change in calorie-restricted Syrian hamsters was also observed in individuals exposed to 14 h:10 h dim light:dark cycles and fed with lower hypocaloric food (i.e. 60% of daily food intake) 2 h after light onset. Moreover, in hamsters housed in constant darkness and fed ad lib., light-induced phase shifts of the locomotor activity in Siberian hamsters, but not in Syrian hamsters were significantly reduced when glucose utilization was blocked by pretreatment with 500 mg/kg i.p. 2-deoxy-D-glucose. Taken together, these results show that the photic synchronization of the light-entrainable pacemaker can be modulated by metabolic cues in Siberian hamsters, but not in Syrian hamsters maintained on long days.

Humanitarian organisations supporting Syrian refugees in Jordan have conducted needs assessments to direct resources appropriately. To present a model of psychosocial concerns reported by Syrian refugees and a peer review of research practices. Academic and grey literature databases, the United Nations Syria Regional Response website, key humanitarian organisation websites and Google were searched for needs assessments with Syrian refugees in Jordan between February 2011 and June 2015. Information directly reporting the views of Syrian refugees regarding psychosocial needs was extracted and a qualitative synthesis was conducted. Respondents reported that psychological distress was exacerbated by both environmental (financial, housing, employment) and psychosocial outcomes (loss of role and social support, inactivity), which are themselves stressors. Need for improvement in research methodology, participatory engagement and ethical reporting was evident. Participatory engagement strategies might help to address identified psychosocial outcomes. More rigorous qualitative methods are required to ensure accuracy of findings. © The Royal College of Psychiatrists 2016.

Cesium-137 inventories and atmospheric fluxes have been determined using radiocesium distributions in undistributed soil profiles, collected from 38 sites distributed all over the Syrian lands. Results have shown that 137 Cs inventories determination by Soil Layers Sum Method is more accurate than the Integration Method, where the best curve fitting of 137 Cs distribution with depth is difficult to establish. 137 Cs inventories ranged from 441 Bq.m - 2 and 13312 Bq.m - 2 using the Layers Sum Method with a mean value of 3679 Bq.m - 2; the highest values observed were in the coastal, middle and north east regions. This is due to the fact that most of Chernobyl accident atmospheric fall-out of cesium 137 had entered the Syrian land came from the west boarders (Mediterranean sea). While the lowest values were found to be in the samples collected from the east south region. In addition, 137 Cs flux ranged from 3.1 kBq m - 2y - 1 and 527.8 kBq m - 2 y - 1 with a mean value of 65.7 kBq m - 2y - 1. Moreover, there was a semi linear relationship found between 137 Cs flux and the height above sea level. While no linear relationship was found between 137 Cs flux and annual rainfall. On the other hand, the external radiation dose to Syrians that due to gamma-rays emitted from cesium 137 decay has been determined and reached a mean value of 166μ Sv.y - 1. This value is about 20% of the radiation dose received by the Syrian from naturally occurring radionuclides in soil. (Author)

As the civil war in Syria enters its fifth year, the Israeli government continues to provide humanitarian aid to Syrian civilians in Israeli hospitals. Many wounded Syrian children are treated at the Galilee Medical Center (GMC). Due to the patients' incomplete medical history and increasing infection rates in Syria, contact isolation and screening cultures for multi-drug resistant bacteria (MDR's) are conducted upon admission for all Syrian children. To describe the rate of MDR carriage in Syrian children and compare it to hospitalized Israeli children. Prospective collection of screening culture data of Syrian patients admitted to GMC between 6/2013-11/2014 and comparison with Israeli children admitted between 1-3/2014. Extended-spectrum beta- lactamase-producing Enterobateriaceae (ESBL), Vancomycin-resistant Enterococcus (VRE), Carbapenem-resistant Enterobacteriaceae (CRE), and Methicillin-resistant Staphylococcus aureus (MRSA) were considered MDR's. Of 47 pediatric Syrian patients, 41 were severely wounded. MDR's were found in 37 (79%) children; most of the isolates were ESBL+ Escherichia coli. Over half of the ESBL's were resistant to additional antibiotics such as sulfa and quinolones; no resistance to amikacin was found. In comparison, in 6 of 40 (15%) Israeli children, MDR's (all ESBL's) were found (p<0.001). In hospitalized Syrian children, contact isolation and screening cultures for MDR's have an important role in the prevention of nosocomial transmission and establishment of empiric antimicrobial protocols. In suspected infections in Syrian children, amikacin and carbapenems are the antimicrobials of choice. MDR's are carried to a lesser extent in Israeli children but due to their importance, further largescale research is needed.

Neutron spectrum in concrete bombarded by 14 MeV neutrons was measured using a miniature NE213 spectrometer and multi-foil activation method. A good agreement between those two experimental methods was obtained within experimental errors. The measured spectrum was compared with calculated ones using two-dimensional transport code DOT3.5 with 125 group structure cross section libraries based on ENDF/B-IV, JENDL-2, and JENDL-3T (the testing version of JENDL-3.) In the D-T neutron peak region, measured and calculated neutron spectra agreed well with each other for those libraries. However, disagreements of about -10 % to +50 % and -30 % to +40 % were obtained in the MeV region and still lower neutron energy range, respectively. As a result, it was concluded that those discrepancies were caused by the overestimation of secondary neutrons emitted by inelastic scattering from O, Si, and/or Ca which were the main components of concrete.

The Syrian conflict has resulted in over 2.3 million child refugees in the Middle East and the prevalence of early marriage has reportedly increased among displaced Syrian families. This study explores the underlying factors contributing to child marriage among Syrian refugees in Lebanon with the goal of informing community-based strategies to address the issue. In July-August 2016, trained interviewers collected self-interpreted stories in Lebanon using Cognitive Edge's SenseMaker, a mixed-method data collection tool. Participants included married and unmarried Syrian girls, Syrian parents as well as married and unmarried men. Each participant shared a story about the experiences of Syrian girls and then interpreted the story by plotting their perspectives on a variety of questions. Patterns in the responses were analysed in SPSS and the accompanying qualitative narratives were reviewed to facilitate interpretation of the quantitative results. 1422 self-interpreted stories from 1346 unique participants were collected with 40% of shared stories focused on (n=332) or mentioning (n=245) child marriage. Quantitative data summarised the different perspectives of female and male participants. Syrian girls and mothers were more likely to share stories about protection/security and/or education and were more likely to report that girls were overprotected. Male participants were more likely to share stories about financial security as well as sexual exploitation of girls and more often reported that girls were not protected enough. Despite these gendered perspectives, many of the shared narratives highlighted similar themes of financial hardship, lack of educational opportunities and safety concerns around sexual and gender-based violence (SGBV). A complex myriad of factors contribute to early marriage including poverty, lack of educational opportunities and concerns about SGBV. Sexual exploitation under the guise of marriage is a reality for some Syrian girls. Gender

Full Text Available Thirty four Syrian isolates of Tomato spotted wilt virus (TSWV collected from tomato and pepper were tested against five specific monoclonal antibodies using TAS-ELISA. The isolates were in two serogroups. Fourteen tomato and sixteen pepper isolates were similar in their reaction with MAb-2, MAb-4, MAb-5 and MAb-6, but did not react with MAb-7 (Serogroup 1. Meanwhile, four isolates collected from pepper reacted with all the MAbs used (Serogroup 2. The expected 620 bp DNA fragment was obtained by RT-PCR from six samples using a specific primer pair designed to amplify the nucleocapsid protein (NP gene of TSWV. The PCR products were sequenced and a phylogenetic tree was constructed. Sequence analysis revealed that the Syrian TSWV isolates were very similar at the nucleotide (97.74 to 99.84% identity and amino acid (96.17 to 99.03% identity sequences levels. The phylogenetic tree showed high similarity of Syrian TSWV isolates with many other representative isolates from different countries.

In view of the importance of in-core measurements the distinction is made between detectors used outside and inside the core. In the former case proportional counters, fission chambers and boron chambers are reviewed in turn. The only in-core detectors considered are those giving a direct measurement, i.e. supplying an electric signal representative of the neutron fluence rate while in the measurement position at the point given. Two kinds of detectors are used for direct measurements: miniature fission chambers and collectors, known also as neutron-electron converters [fr

Full Text Available The current globalization system interconnects conflicts, problems and social policies in such a way that they do not only concern their countries of origin, but all the nations in the world. This paper is a bibliographic review with two main lines. The first one is focused on the root causes of the Syrian War and, as a consequence, the thousands of Syrian refugees it created. They were forced to flee from their country, and had to face several difficulties and overcome all kind of obstacles, which has been the source of many tragedies. The contribution of resilience as a social intervention approach with Syrian refugees from the point of view of Social Work is the second line of this paper. This social intervention approach is aimed at strengthening and empowering people against adversity in order to cope with trauma. This objective and the purpose of Social Work are one and the same: to guarantee and promote Human Rights all over the world.

Refugees have had major challenges to meet their health care needs throughout history especially in war zones and natural disaster times. The health care needs of Syrian refugees have been becoming an increasingly important issue. We aimed to examine the prevalence of post-traumatic stress disorder (PTSD) and explore its relation with various socioeconomic variables among Syrian refugees, who sought asylum in Turkey. This cross-sectional study was conducted in a tent city. Sample size calculation yielded 352 and the participants of the study were determined randomly. Experienced and native Arabic speaking, psychiatrist evaluated the participants. The frequency of PTSD was 33.5%. Through the binary logistic regression analysis, we calculated that the probability of having PTSD among Syrian refugees in our sample was 71%, if they had the following features: with female gender; being diagnosed with psychiatric disorder in the past; having a family history of psychiatric disorder; and experiencing 2 or more traumas. The findings of our study suggest that PTSD among Syrian refugees in Turkey might be an important mental health issue in refugee camps especially among female refugees, who were exposed to 2 or more traumatic events and had a personal or family history of psychiatric disorder.

The Ghana Research Reactor-1 (GHARR-1) is a commercial version of the Miniature Neutron Source Reactor (MNSR) and has operated at different power levels since its commissioning in March 1995. As required for all nuclear reactors, neutronic and thermal hydraulic analysis are being performed for the HEU-LEU core conversion studies of the Ghana Research Reactor-1 (GHARR-1) facility, which is a commercial version of the Miniature Neutron Source Reactor (MNSR). Stochastic Monte Carlo particle transport methods and tools (MCNP4c/MCNP5) were used to fine-tune a previously developed 3-D MCNP model of the GHARR-1 facility and perform neutronic analysis of the 90.2% HEU reference and candidate LEU (UO{sub 2}, U{sub 3}Si{sub 2}, U-9Mo) fresh cores with varying enrichments from 12.6%-19.75%. In this paper, the results of the progress made in the Monte Carlo neutronic analysis of the HEU reference and candidate LEU fuels are presented. In particular, a comparative performance assessment of the LEU with respect to neutron flux variations in the fission chamber and experimental irradiation channels are highlighted.

2016-08-01

Full Text Available A 14-month-old intact male Syrian hamster was admitted for lethargy and hematuria. A total body radiographic image and abdominal ultrasonography showed the presence of a vesical calculus. During cystotomy, a sterile urine sample was obtained and sent to the diagnostic laboratory along with the urolith for analysis. Urine culture was found negative for bacterial growth, and the urolith was identified as a calcium-oxalate stone. Diet supplementation with palmitoylethanolamide, glucosamine and hesperidin was adopted the day after discharge. One year follow up revealed no presence of vesical calculi. Although this is the report of a single clinical case, this outcome differs from the results reported in the literature characterized by recurrences after few months. Considering the positive outcome and the beneficial properties of palmitoylethanolamide, glucosamine, and hesperidin, these nutritional elements in Syrian hamsters, are recommended to reduce recurrence after surgical treatment of urolithiasis.

In this report, we present the feasibility study of using pre-cracked miniature multi-notch bend bar specimens (M4CVN) with a dimension of 45mm (length) x 3.3mm (width) x 1.65mm (thickness) to characterize the transition fracture toughness of Eurofer97 based on the ASTM E1921 Master Curve method. From literature survey results, we did not find any obvious specimen size effects on the measured fracture toughness of unirradiated Eurofer97. Nonetheless, in order to exclude the specimen size effect on the measured fracture toughness of neutron irradiated Eurofer97, comparison of results obtained from larger size specimens with those from smaller size specimens after neutron irradiation is necessary, which is not practical and can be formidably expensive. However, limited literature results indicate that the transition fracture toughness of Eurofer97 obtained from different specimen sizes and geometries followed the similar irradiation embrittlement trend. We then described the newly designed experimental setup to be used for testing neutron irradiated Eurofer97 pre-cracked M4CVN bend bars in the hot cell. We recently used the same setup for testing neutron irradiated F82H pre-cracked miniature multi-notch bend bars with great success. Considering the similarity in materials, specimen types, and the nature of tests between Eurofer97 and F82H, we believe the newly designed experimental setup can be used successfully in fracture toughness testing of Eurofer97 pre-cracked M4CVN specimens.

The civil war in Syria that began in 2011 has displaced millions of Syrians of all ages. While the number that have arrived in the United States is small in comparison to many other countries, it is important that nurses and other healthcare workers here understand that many of them have faced considerable trauma and endured stresses. Most of them are Muslims. Muslims in the United States and elsewhere represent a heterogeneous group of people with a long intellectual and cultural history. Islamic cultural patterns do pose unique barriers to a primarily Anglo-Saxon medical system that medical practitioners need to consider in order to avoid misunderstanding and provide culturally sensitive care. The authors discuss the Syrian refugee crisis and the experience of being a Muslim or Arab American patient in U.S. healthcare settings.

The current study explores the perceived quality of life of Syrian refugees who have entered the Kurdistan Region of Iraq. Two hundred and seventy participants residing in refugee camps in the Erbil region in Kurdistan completed the WHOQOL-BREF, which measures Quality of Life (QOL) within four domains; physical, psychological, social relationships and environment. Syrian refugees in Kurdistan scored significantly lower for general population norms on physical health, psychological and environment QOL, and score significantly lower for physical health and psychological QOL for refugees in the Gaza strip. However, respondents in the current sample scored significantly higher on environment QOL compared to refugees in the Gaza strip, and significantly higher on all the QOL domains than those reported for refugees in West Africa. Finally, Syrian refugees in Kurdistan scored significantly higher than general population norms for social relationships QOL. The current findings provide the first report of QOL domain scores among Syrian refugees in the Kurdistan camps and suggest that social relationships and environmental QOL circumstances are relatively satisfactory, and that further investigation might be focused on physical and psychological QOL.

In recent years, there had been much interest in the concentrations of trace metals occurring in human and animal tissues and in the manner in which these concentrations may alter in malignant and other diseases. Neutron activation analysis is consider one of several methods that have been described for the determination of trace elements in biological materials. This method possesses the sensitivity and specificity necessary for the estimation at the concentrations existing naturally in most tissues, particularly when only small samples are available for analysis. The purpose of this study was to compare blood concentrations of trace elements Co, Cr, Fe, Rb, Sc, Se, Th, and Zn of lymphomas Syrian patients with those of healthy volunteers. Also, determine the relationships between trace elements concentration and the histological type of lymphomas. The blood samples were collected from 39 healthy volunteers and 49 patients with histologically confirmed lymphomas (29 Hodgkin's HL and 20 non-Hodgkin's lymphomas NHL), and analyzed to obtain the concentration of the trace elements in blood. Then, comparison between the healthy volunteers and lymphomas patients (both HL and NHL) was made to elucidate differences of the concentration distributions of the elements in blood. However, statistical analysis using Student's t test revealed significantly high concentrations of Co, Cr, Sc, and Th in lymphoma patients. Whereas Fe and Rb were found significantly decreased in lymphomas patient comparing to control group. Increasing or decreasing concentrations of Se and Zn in lymphoma patients was found not significant. Comparison between the healthy volunteers and non-Hodgkin's lymphomas patients reveled that Co, Cr, Sc, and Th were significantly elevated whereas, Rb only one trace element was decreased and all change in concentrations (elevating or decreasing) of Se and Zn were not significant. Comparison between the healthy volunteers and Hodgkin

To compare obstetric and perinatal outcomes of Syrian refugee pregnants and Turkish counterparts who gave birth at a tertiary center in İstanbul. A retrospective study including the birth records of 704 Syrian refugees and 744 Turkish pregnant women between January 2016 and May 2017 were analyzed. Demographic data, obstetric and neonatal outcomes were compared. The primary aims of this study were to evaluate the pregnancy outcomes and cesarean rates between the groups. The secondary outcomes were the use of antenatal vitamin supplementation, hemoglobin-hematocrit values, and maternal complications. Our results showed that the use of folic acid and iron supplementation rates during pregnancy were similar between the groups (folic acid supplementation 8.1% vs 6.5%, p=0.264; iron supplementation 20.7% vs 19.6%, p=0.125; respectively for Turkish women and Syrian refugees). Cesarean rates were significantly higher for Turkish patients than in Syrian refugees (42.7% vs 32.7%; pyrian refugees (37.7±2.3 vs 36.4±2.3 weeks, pyrian refugees, respectively, p=0.105). Although obstetric complications were seen more often in Syrian refugees, it did not reach statistical difference (9.7% vs 8.1%, respectively, p=0.285). Syrian refugees use antenatal vitamin supplementations at similar rates to Turkish citizens and obstetric and perinatal outcomes are similar between the groups.

By the summer of 2014, the Syrian crisis resulted in a regional humanitarian emergency with 2.9 million refugees, including 608,000 in Jordan. These refugees access United Nations High Commissioner for Refugees (UNHCR)-sponsored clinics or Jordan Ministry of Health clinics, including tuberculosis diagnosis and treatment. Tuberculosis care in Syria has deteriorated with destroyed health infrastructure and drug supply chain. Syrian refugees may have undiagnosed tuberculosis; therefore, the UNHCR, the International Organization for Migration (IOM), the National Tuberculosis Program (NTP), and the Centers for Disease Control and Prevention developed the Public Health Strategy for Tuberculosis among Syrian Refugees in Jordan. This case study presents that strategy, its impact, and recommendations for other neighboring countries. UNHCR determined that World Health Organization (WHO) criteria for implementing a tuberculosis program in an emergency were met for the Syrian refugees in Jordan. Jordan NTP assessed their tuberculosis program and found that access to Syrian refugees was the one component of their program missing. Therefore, a strategy for tuberculosis control among Syrian refugees was developed. Since that development through work with IOM, UNHCR, and NTP, tuberculosis case detection among Syrian refugees is almost 40 % greater (74 cases/12 months or 1.01/100,000 monthly through June 2014 vs. 56 cases/16 months or 0.73/100,000 monthly through June 2013) using estimated population figures; more than two fold the 2012 Jordan tuberculosis incidence. Additionally, the WHO objective of curing ≥85 % of newly identified infectious tuberculosis cases was met among Syrian refugees. Tuberculosis (TB) rates among displaced persons are high, but increased detection is possible. High TB rates were found among Syrian refugees through active screening and will probably persist as the Syrian crisis continues. Active screening can detect tuberculosis early and reduce risk

Perspectives of application of isotope techniques in hydrology in the Syrian Arab Republic

1986-01-01

The Syrian Arab territories are located in the warm moderate region, under arid and semi-arid conditions. In spite of the occurrence of main springs and permanent rivers, groundwater resources available are a limiting factor for socio-economic development in several Syrian regions. Investigation and development of these resources are facing serious problems, for which the application of isotope and nuclear techniques could be a significant process and a deterministic tool. So far, and on the light of current applications, the Syrian Arab Republic is already involved in the isotopic hydrology sector, and so it is needful to set up, in the near future, a relevant unit, on a centralized basis covering the concerned authorities demands, under co-ordinated and integrated conditions. The international co-operation would be of a concrete importance in this respect, to provide the mentioned unit with equipment, training of scientific and technical staff, and consultancy services during the period of establishment. 14 refs.

Studies were designed to identify genes induced following low-dose neutron but not following γ-ray exposure in fibroblasts. Our past work had shown differences in the expression of β-protein kinase C and c-fos genes, both being induced following γ-ray but not neutron exposure. We have identified two genes that are induced following neutron, but not γ-ray, exposure: Rp-8 (a gene induced by apoptosis) and the long terminal repeat (LTR) of the human immunodeficiency (HIV). Rp-8 mRNA induction was demonstrated in Syrian hamster embryo fibroblasts and was found to be induced in cells exposed to neutrons administered at low (0.5 cGy/min) and at high dose rate (12 cGy/min). The induction of transcription from the LTR of HIV was demonstrated in HeLa cells bearing a transfected construct of the chloramphenicol acetyl transferase (CAT) gene driven by the HIV-LTR promoter. Measures of CAT activity and CAT transcripts following irradiation demonstrated an unresponsiveness to γ rays over a broad range of doses. Twofold induction of the HIV-LTR was detected following neutron exposure (48 cGy) administered at low (0.5 cGy/min) but not high (12 cGy/min) dose rates. Ultraviolet-mediated HIV-LTR induction was inhibited by low-dose-rate neutron exposure

Syrian refugees in Kurdistan scored significantly lower for general population norms on physical health, psychological and environment QOL, and score significantly lower for physical health and psychological QOL for refugees in the Gaza strip. However, respondents in the current sample scored significantly higher on environment QOL compared to refugees in the Gaza strip, and significantly higher on all the QOL domains than those reported for refugees in West Africa. Finally, Syrian refugees in Kurdistan scored significantly higher than general population norms for social relationships QOL. The current findings provide the first report of QOL domain scores among Syrian refugees in the Kurdistan camps and suggest that social relationships and environmental QOL circumstances are relatively satisfactory, and that further investigation might be focused on physical and psychological QOL.

Many surveys have underlined the high levels of distress Syrian refugees have endured since the conflict aroused in their country, yet few have used reliable diagnostic tools for the clinical assessment of resulting mental disorders. The aim of our study is to assess for the onset of new depressive disorders following the Syrian war, and to investigate the correlation of religiosity with depression. Single individual interviews were used, in a sample of 310 Syrian forced migrants, retrospectively assessing for depressive disorders with onset at different timelines of the conflict outbreak. Religiosity was assessed in a cross-sectional design using a reliable, recently developed and tested tool. Bivariate analysis and logistic regression analysis were used with a level of significance at 0.05. The prevalence of current depression was 43.9% (95% Confidence Interval (CI): 38.5-49.4%) with no difference across all socio-demographic factors, including gender. The overall mean for religiosity for the current sample was moderate (mean=9.76; standard deviation SD=2.34). No substantial correlation was found with religiosity. The prevalence rate for pre-war depression was 6.5% (95% CI: 4.2-9.8%) following the global pattern of socio-demographic epidemiological characteristics. Prevalence for past depression was 27.1% (95% CI: 22.5-32.3%); for current dysthymia: 4.5% (95% CI: 2.7-7.4%); for prewar and past dysthymia: 1% (95% CI: 0.3-2.8%), all with no significant differences detected across all demographic variables. In this retrospective study on a sample of Syrian refugees who fled their country after the war, we found a substantial emergence of depressive disorders with no meaningful correlation with the level of religiosity.

The aim of thus study is to investigate the risk of exposure to Uranium and its radioactive products in Syrian phosphate miners (Khneefees and Al-sharkia). Chromosomal aberrations have been estimated in peripheral blood lymphocytes of miners using whole blood cultures `in vitro` for 48 hrs. The control group has been the normal population in damascus 180 km far from khneefees and 210 km from Al-sharkia. Our results have shown a significant difference between the miners and our control group; however there was no significant difference between the two miners groups. These results show an accumulative biological effect induced by environmental contamination in the Syrian phosphate mines. 3 figs., 3 tabs.

Recent reports have suggested that child marriage among Syrians may be increasing as a result of displacement and conflict. This study sought to gather qualitative data about the factors that promote child marriage practices among Syrian refugees in Al Marj area in the Bekaa valley, Lebanon, where the majority of Syrian refugees have settled in Lebanon. The second aim of this study was to generate recommendations on how to mitigate the drivers and consequences of child marriage practices based on the findings. Eight focus group discussions were conducted separately with married and unmarried young women and mothers and fathers of married and unmarried women. Furthermore, researchers conducted 11 key informant interviews with service providers and stakeholders to understand how conflict and displacement influenced marriage practices of Syrian refugees in Al Marj community. Although child marriage was a common practice in pre-conflict Syria, new factors seem to contribute to a higher risk of child marriage among Syrian refugees in Lebanon. Respondents cited conflict- and displacement-related safety issues and feeling of insecurity, the worsening of economic conditions, and disrupted education for adolescent women as driving factors. Service providers, young women, and parents also reported changes in some marriage practices, including a shorter engagement period, lower bride price, change in cousin marriage practices, and a reduced age at marriage. Recommendations for interventions to mitigate the drivers of child marriage and its negative consequences should be built on a clear understanding of the local refugee context and the drivers of child marriage in refugee settings. Interventions should involve multiple stakeholders, they should be adjusted to target each specific context, age group and marital status. For these interventions to be effective, they should be addressed concurrently, and they should be delivered in a culturally sensitive and practical manner.

Norm waste in oil and gas industry: The Syrian experience

International Nuclear Information System (INIS)

Al-Masri, M.S.; Suman, H.

2001-01-01

This paper describes the Syrian experience in respect to Naturally Occurring Radioactive Materials (NORM) waste in Syrian oil and gas industry. NORM can be concentrated and accumulated in tubing and surface equipment of oil and gas production lines in the form of scale and sludge. NORM waste (scale, sludge, production water) is therefore generated during cleaning, physical or chemical treatment of streams. Uncontrolled disposal of this type of waste could lead to environmental pollution, and thus eventually to exposure of members of the public. The presence of NORM in Syrian oil fields has been recognized since 1987 and AECS has initiated several studies, in cooperation with oil companies, to manage such type of waste. Three categories of NORM waste in Syrian oil fields were identified. Firstly, hard scales from either decontamination of contaminated equipment and tubular using high-pressure water systems or mechanical cleaning at site are considered to contain the highest levels of radium isotopes ( 226 Ra, 228 Ra, 224 Ra). Secondly, sludge wastes are generated with large amount but low levels of radium isotopes were found. Thirdly, contaminated soil with 226 Ra as a result of uncontrolled disposal of production water was also considered as NORM waste. The first waste type (scale) is stored in Standard storage barrels in a controlled area; the number of barrels is increasing with time. High levels of radium isotopes were found in these scales. The options for disposal of these wastes are still under investigations; one of the most predominant thinking is the re-injection into abundant wells. For sludge waste, plastic lined disposal pits were constructed in each area for temporary storage. Moreover, big gas power stations have been built and operated since the last ten years. Maintenance operations for these stations produce tens of tones of scales containing radon daughters, 210 Pb and 210 Po with relatively high concentrations. The common practice used to dispose

More than one hundred different food stuffs (meat, vegetables cereals, seafood,..) have been collected during 1998, 1999 and 2000 and analyzed for radioactivity as part of the National Food Monitoring Program in Syria. Results have shown that most of the observed concentrations were within the range of the worldwide values with the exception of relatively high levels of 210 Po being observed in fish, vegetables, mushrooms, herbs and flowers. The daily intakes of the radionuclides studied have been evaluated. Relatively high values, in comparison with some countries, were found for 210 Po (1.9 Bq/day). This is due to high content of 210 Po in wheat (2.3 Bq/kg) consumed by Syrians, the daily consumption of wheat by Syrians is about 526 g. In addition, natural and artificial radionuclides in some manufactured food of Syrian infant and their intake rates have been determined. Seventeen manufactured food and eleven types of canned milk were collected from the local market and their radioactivity analyzed. 210 Po activity concentration varied between 0.38 and 2.89 Bq/kg dry wt. in canned milk while the highest concentration in infant food was found to be 1.69 Bq/kg dry wt. Other radionuclide concentrations were below the limit of detection of 3 Bq/kg dry wt. and 4 Bq/kg dry wt. for 22' 6Ra and 228 Ra, respectively, while uranium concentration varied between 2.2 and 10.5 μg/kg dry wt. in milk samples and 0.78-6.0 μg/kg dry wt. in other food samples.

The study was conducted to assess the health needs of urban refugees living in İstanbul. A mixed methods approach was adopted to interview Syrian women from households, doctors, decision makers and NGO representatives. The data were collected between June and October 2015. The main challenges were the cost of living in İstanbul, increased rent and language barrier. Almost half (49.6%) of the interviewed women did not know about free health care rights for Syrians. In the last 30 days preceding the interview, 58.6% of the participants sought health care primarily through state hospitals, primary health care centres and pharmacies. The participants had difficulty in accessing health care due to the language barrier and a lack of knowledge of the Turkish health care system. Waiting time at hospitals and negative attitudes of health care staff reduced satisfaction in these services. In relation to life in Turkey, the main issues for Syrian refugees were not directly related to health. They have been given the right to access health care, although had many difficulties in understanding and accessing services in a crowded city.

The Syrian public health and humanitarian crisis: A 'displacement' in global governance?

Science.gov (United States)

Akbarzada, Sumaira; Mackey, Tim K

2018-07-01

Ongoing failure by the international community to resolve the Syrian conflict has led to destruction of critical infrastructure. This includes the collapse of the Syrian health system, leaving millions of internally displaced persons (IDPs) in urgent need of healthcare services. As the conflict intensifies, IDP populations are suffering from infectious and non-communicable disease risks, poor maternal and child health outcomes, trauma, and mental health issues, while healthcare workers continually exit the country. Healthcare workers who remain face significant challenges, including systematic attacks on healthcare facilities and conditions that severely inhibit healthcare delivery and assistance. Within this conflict-driven public health crisis, the most susceptible population is arguably the IDP. Though the fundamental 'right to health' is a recognised international legal principle, its application is inadequate due to limited recognition by the UN Security Council and stymied global governance by the broader international community. These factors have also negatively impacted other vulnerable groups other than IDPs, such as refugees and ethnic minorities, who may or may not be displaced. Hence, this article reviews the current Syrian conflict, assesses challenges with local and global governance for IDPs, and explores potential governance solutions needed to address this health and humanitarian crisis.

We aimed to compare the clinical characteristics and pregnancy outcomes in women who are Syrian refugees and Turkish women who are non-refugees at a maternity center in Istanbul, Turkey. A total of 600 singleton pregnancies who delivered at Sisli Hamidiye Etfal Training and Research Hospital were included in the study. Demographic data, obstetrical history, clinical findings, obstetrical and neonatal outcomes were compared between 300 Syrian refugees and 300 control patients. The Syrian refugee patients were significantly younger than Turkish patients. The percentage of adolescents aged 12-19 years were significantly higher in the Syrian patients (14.3 vs. 5.3 %, p refugee patients had no antenatal care. However, this ratio was only 7.7 % for the control group (p refugee control patients, refugee women in our study had poor antenatal care but no adverse perinatal outcomes were observed. Further larger multicenter studies may provide more convincing data about obstetric outcomes in the Syrian refugee population as well as adolescent pregnancies in this population.

The Brotherhood Medical Center: Collaborative Foundation of Maternity and Children’s Healthcare Facility for Displaced Syrians

2018-01-01

The United Nations has declared the Syrian conflict, with more than 50% of Syria’s population currently displaced, as the worst humanitarian crisis of the twenty-first century. The Syrian conflict has led to a collapse of infrastructure, including access to critical and lifesaving healthcare services. Women and children account for approximately 75% of internally displaced Syrians and refugees. This population is also particularly vulnerable to poor health outcomes, a condition worsened by lack of access to maternal and child health services. In response to this crisis, a partnership of Saudi and Syrian physicians established a non-profit healthcare facility named the Brotherhood Medical Center (BMC) to serve women and children within a safe area near the Syrian–Turkish border. The project began in September 2014 and was implemented in three phases of establishment, phased construction and formal launch and operation. Currently, the BMC is working at about 70% of its capacity and is run in partnership with the Syrian Expatriate Medical Association. Although there was strong initial support from donors, the BMC continues to face many financial and operational challenges, including difficulties in transferring money to Syria, shortage of medical supplies, and lack of qualified medical personnel. Despite these challenges, the BMC represents a critical model and an important case study of the challenges of delivering healthcare services to underserved populations during an ongoing conflict. However, more robust support from the international community is needed to ensure it continues its important health and humanitarian mission. PMID:29721489

Previous work has shown that exposure of cells to ionizing radiations causes modulation of a variety of genes, including those encoding c-fos, interleukin-1, tumor necrosis factor, cytoskeletal elements, and many more. The experiments reported herein were designed to examine the effects of either JANUS neutron or γ-ray exposure on expression of genes encoding nucleus-associated proteins (H4-histone, c-jun, c-myc, Rb, and p53). Cycling Syrian hamster embryo cells were irradiated with varying doses and dose rates of either JANUS fission-spectrum neutrons or γ-rays; after incubation of the cell cultures for 1 h following radiation exposure, mRNA was harvested and analyzed by Northern blot. Results revealed induction of transcripts for c-jun, H4-histone, and Rb following γ-ray but not following neutron exposure. Interestingly, expression of c-myc was repressed following γ-ray but not following neutron exposure. Radiations at different doses and dose rates were compared for each of the genes studied

Systemic violence against Syrian refugee women and the myth of effective intrapersonal interventions.

Science.gov (United States)

Yasmine, Rola; Moughalian, Catherine

2016-05-01

Since the uprising in Syria in March 2011, over 4.3 million Syrians have fled to neighboring countries. Over a million have sought refuge in Lebanon, constituting almost a quarter of the Lebanese population and becoming the largest refugee population per capita in the world. With inequitable health coverage being a longstanding problem in Lebanon, Syrian refugee women's health, and specifically their sexual and reproductive health, is disproportionately affected. An increase in gender-based violence and early marriage, a lack of access to emergency obstetric care, limited access to contraception, forced cesarean sections, and high cost of healthcare services, all contribute to poor sexual and reproductive health. In this commentary, we conceptualize violence against Syrian refugee women using the ecological model, exploring the intersections of discrimination based on ethnicity, gender, and socioeconomic status, while critiquing interventions that focus solely on the intrapersonal level and ignore the role of microsystemic, exosystemic, and macrosystemic factors of negative influence. These social determinants of health supersede the individual realm of health behavior, and hinder women in taking decisions about their sexual and reproductive health. Copyright © 2016 Elsevier Inc.

Sex division of labour in Syrian school textbooks

Science.gov (United States)

Alrabaa, Sami

1985-12-01

The sexist division of labour, particularly in the occupational sector, which is believed to be more eminent in developing countries than in the developed ones, is reinforced by school textbooks. This state of affairs is hampering sex-role equality on the way to emancipation. Various Syrian school textbooks have been scrutinized and proved to be malebiased in content and language. Despite quantitative growth of education, the emancipatory quality of the school textbooks leaves much to be desired. The government has had the chance since 1963 to produce textbooks conductive to its promise of sex-role equality in education. The textbooks portray males for a bustling world of decision making, while conditioning the females to seek fulfilment in the background where servitude and support are the only requirement. Females are derogated and victimized. These contents, which are internalized at school and reproduced in society, certainly do not serve development. The exclusion of one-half of the population from contributing to the tasks of development is a waste of human talent which no society can afford. Furthermore, the sexist portrayal of females in Syrian textbooks is a pale reflection of Arab women in Arab history and literature.

Radiation-induced anorexia in Syrian hamsters

Energy Technology Data Exchange (ETDEWEB)

Kindt, A.; Sattler, E.L.; Schraub, A.

1980-10-01

The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation.

Full Text Available Instead of hastening political change, the Syrian uprising has led to greater authoritarianism. At first, president Bashar al-Assad adopted various cosmetic reforms (a party law and constitutional referendum, which were designed more as a survival strategy than a genuine process of political liberalisation. In its first four years, the Syrian crisis has gone from being an anti-authoritarian popular uprising to a proxy war with the active presence of Saudi Arabia, Iran, Qatar and Turkey. Control of the state apparatus on the part of the Alawite minority has been instrumentalised by the Salafist and jihadist groups to intensify sectarianism and claim the establishment of an Islamic State.

In war areas a lot of children die as well as adults. According to UNICEF, almost 2 million children have died in the wars took place in the last 10 years. In this study, we aimed to evaluate demographical data and injury characteristics of Syrian children who were wounded in Syria Civil War and died while being treated in Turkey. Postmortem examination and autopsy reports of 985 forensic deaths from Hatay -a Syrian neighborhood city of Turkey-between January 2012 and August 2014 were analyzed retrospectively. Among 763 Syrian people who were wounded in the war and died while being treated in Turkey, 140 cases (18.3%) who were younger than 18 years of age were taken into the scope of this study. Among those cases 77.9% (n = 109) were male and 22.1% were female. Median ages of female cases are 14 (min-max: 2-18) and median age of female cases are 9 (min-max: 1-18). Frequency distribution is highest between 13 and 18 years of age (n: 71, 50.7%). In 70% (n: 98) of cases, cause of death is bombing and shrapnel injuries, 13.6% (19) of them were killed by gunshot wounds. According to injury sites most of the injuries were reported to be on multiple body parts (54.3%, n: 76) and only head and neck injuries (%30). Cause of death was intracranial bleeding and cerebral parenchymal injury in most of the cases (n: 66, %47.1) followed by vascular damage with external bleeding (n: 15, %10.7) and internal organ damage with internal bleeding (n: 15, %10.7). The cases had very high level Abbreviated Injury Scales and Injury Severity Sores. In conclusion, a lot of children have died in the Civil War of Syria. Their average abbreviated injury scale and injury severity score values reported very high. Children that we evaluated were mostly died of head and neck injuries predominantly caused by bombing attacks and Autopsies of them revealed fatal intracranial hemorrhages and parenchymal injuries.

Establishing capabilities for combating illicit trafficking: the Syrian experience

International Nuclear Information System (INIS)

Othman, I.; Suman, H.

2008-01-01

Since the late 80's, Syria has been taking steps towards combating illicit trafficking or inadvertent movement involving radioactive or nuclear material within the country or across its border. By applying the proper combination of technical and procedural measures, an acceptable level of performance has been achieved. The measures undertaken by AECS include anticipative measures, which aim at identifying potential loss of control over radioactive sources and potential illicit trafficking within the country, as well as defensive measures which aim at detection of and response to events of illicit trafficking. In addition, a tight follow up of radiation source along their entire lifetime in the Syrian territory, supported by proper data analysis is one of the most efficient tools for identifying potential loss of control over sources. AECS has established Border Monitoring Centers (BMC) in almost all border crossings. They work in close cooperation with the customs and other relevant authorities at the Syrian borders. AECS has been also providing the necessary training for the frontline officers. (author)

The conflict in Syria that began in 2011 has resulted in the exodus of over 5 million Syrian refugees to neighbouring countries, with more than one million refugees currently registered by UNHCR in Lebanon. While some are living in tented settlements, the majority are living in strained conditions in rented accommodation or collective shelters in the Bekaa Valley next to Syria. Adolescents are particularly vulnerable in any crisis. In 2013-4, the American University in Beirut in collaboration with the Women's Refugee Commission, Johns Hopkins and Save the Children, sought to understand the specific experiences of very young adolescents, those 10-14 years of age, in this protracted crisis context. The study was conducted in 2014 in Barelias and Qabelias - two urban areas located close to each other in the Beka'a valley that has a large concentration of Syrian refugees. Focus group discussions (FGDs), including community mapping and photo elicitation, were conducted with 10-12 and 13-14 year old Syrian refugee adolescents, in order to obtain information about their experiences and perspectives. FGDs were also implemented with 15-16 year old Syrian refugees and separately also with adult refugees, to consider their perspectives on the needs and risks of these adolescents. A total of 16 FGD (8 for each sex, with 6-9 participants in each) were conducted in Arabic across the two sites, with 59 female participants and 59 male participants. The experiences and risks faced by these adolescents were significantly impacted by economic strain and loss of educational opportunities during displacement, and only a minority of adolescents in the study reported attending school. Additionally, on-going protection risks for girls were felt to be higher due to the crisis and displacement. In Lebanon this has resulted in increased risks of child marriage and limitations in mobility for adolescent girls. Adolescents, themselves expressed tensions with their Lebanese counterparts and

The Syrian Vulnerable Person Resettlement Programme: evaluation of Edinburgh's reception arrangements.

2017-11-07

During 2015 and 2016 a group of Syrian refugees were resettled in Edinburgh, Scotland under the United Kingdom Government Syrian Vulnerable Person Resettlement Programme. We evaluate the strengths and weaknesses of the settling in arrangements for these refugees. Semi-structured interviews were conducted with five Arabic interpreters who had worked extensively with these refugees. Interviews sought their impressions about what went well or was not successful. Interviews were transcribed and key themes extracted and analysed. Six themes emerged: 'first impressions', language skills, different healthcare systems, health of the refugees, relationships between the interpreters and refugees and support for the interpreters. The welcoming arrangements went well and exceeded refugees' and interpreters' expectations. There was perhaps too much information given immediately and reinforcing details about various public services and facilities after a first few months would be worthwhile. The Syrians were unfamiliar with NHS structures and found lack of direct specialist access surprising. Problems were amplified by low English levels. A need for Arabic literacy classes was also identified. Interpreters were often used informally out-of-hours and a better system with first contact in Arabic should be established. Interpreters find this work particularly stressful and the provision of psychological support for them should be prioritized. © The Author 2017.

The ongoing Syrian war has resulted in many changes in the social and economic life of Syrians. To date, no study has documented the relationship between smoking behaviour and the war. To determine the prevalence of cigarette smoking among university students during the crisis in Damascus, Syrian Arab Republic, and the impact of the war on smoking behaviour. We conducted an anonymous online cross-sectional survey of 1027 undergraduate students from all years and colleges at Damascus University. The overall prevalence of tobacco smoking was 24.73% for cigarettes and 30.4% for waterpipe. Prevalence of cigarette smoking was significantly higher in men, non-health profession students, and in students living away from their families. There was no significant difference in prevalence of smoking cigarettes when comparing students according to their origin (urban vs rural), year of study, and change of residence due to war. War was associated with a significant increase in mean number of cigarettes smoked daily, and 53.1% of smokers reported that the number of cigarettes consumed per day had increased since the beginning of the war. Increased smoking is an additional health concern in areas of conflict and may require special consideration and efforts by public health authorities.

Miniature proportional counter for compression measurements of laser-fusion targets

International Nuclear Information System (INIS)

Lane, S.M.; Dellis, J.H.; Bennett, C.K.; Campbell, E.M.

1981-10-01

Direct drive laser fusion targets consisting of DT gas encapsulated in glass microshells produce 14.1 MeV neutrons that can interact with silicon-28 nuclei in the glass to produce a 2.2 minute aluminum-28 activity. From the number of 28 Al nuclei created and the neutron yield, the compressed glass areal density can be found. To determine the number of activated atoms created, we collect approximately one-half of the target debris on a thin metal foil which is transferred to our beta-gamma coincidence detector. This detector consists of a 25 cm x 25 cm NaI(Tl) crystal having a 5 cm x 15 cm well. We have recently built a miniature proportional counter that fits into this well and is used to detect beta particles. It is constructed of .025 cm thick copper and has nine separate chambers through which methane flows. The coincidence background is 0.14 cpm and the measured beta efficiency is 45%. We are now building a .0125 cm thick counter made of aluminum having a predicted efficiency of > 90%

Helium production measurements for neutron dosimetry and damage correlations

Farrar, H. IV; Lippincott, E.P.

1978-01-01

Helium accumulation fluence monitors (HAFM's), consisting of miniature vanadium capsules containing small, accurately-known amounts of 10 B or 6 Li, are being used routinely for neutron dosimetry measurements in breeder reactor environments. Additionally, solid wires of Al, Fe and Cu have been irradiated by 14.8-MeV neutrons from the d-T reaction, and measurements of the helium production along these wires have given detailed neutron fluence profiles. Additional materials with relatively high (n,α) cross sections are being tested in a wide variety of neutron environments to select HAFM sets that will provide spectral information by unfolding techniques. The mass spectrometric helium measurement technique has been demonstrated to produce results with better than 2% (1 sigma) absolute accuracy. Intercomparisons with other laboratories have demonstrated good correlations with radiometric and fission chamber dosimetry results

2016-01-01

With over one million Syrian refugee children in the region, we undertook this study to characterize care-seeking behaviors and health service utilization for child refugees with the aim of informing humanitarian programming for non-camp settings in Jordan. A survey of Syrian refugees living outside of camps in Jordan was conducted using a 125 × 12 cluster design with probability proportional to size sampling to obtain a representative sample. The questionnaire focused on access to health services, including a module on care seeking for children. Care seeking was high with 90.9% of households with a child less than 18 years seeking medical care the last time it was needed. Households most often sought care for children in the public sector (54.6%), followed by private (36.5%) and charity sectors (8.9%). Among child care seekers, 88.6% were prescribed medication during the most recent visit, 90.6% of which obtained the medication. Overall, 49.4% of households reported out-of-pocket expenditures for either the consultation or prescribed medications at the most recent visit (mean $US21.1 and median $US0). Syrian refugees had good access to care for their sick children at the time of the survey; however, this has likely deteriorated since the survey because of the withdrawal of free access for refugees. The number of refugees in Jordan and relative accessibility of care has resulted in a large burden on the health system; the Jordanian government will require additional support if current levels of health access are to be maintained for Syrian refugees. © 2016 The Authors.

The aim of this study was to investigate the effect of Syrian refugees on the pharmaceutical sector in Jordan. Based on a standardized methodology developed by the WHO, Level II Facility (2009) structured questionnaires (including: medicine access [availability, affordability and geographical accessibility], quality, and rational use of medicines) were used to investigate the effect of Syrian refugees influx on the pharmaceutical sector in Jordan. Lists of essential medicines (N = 50) were included in the survey forms. The results showed more progress in all indicators for the public sector compared with the previous results in the 2009 survey and in comparison to the private sector. For example, access to medicines improved in the public sector while it decreased (if it did not remain the same) in the private sector. Also, average stock out duration time decreased dramatically in both public and private sectors. As indicated by the median price ratio (MPR), brand prices increased much in the public health facilities while they decreased by 23%-30% in the private sector. In northern areas where most Syrian refugees stay, a significant decrease in availability was noticed, in addition to the dramatic decrease in days of average stock out and adequate inventory record percentage of those medicines. In conclusion, despite the international help received to support health care provision and medications procurement for the refugees, more support is needed immediately.

Ammouneh, H.; Arabi, M.; Shoaib, A.

2011-01-01

Thirty Erwinia amylovora strains, collected from the main rosaceous crop-growing regions in Syria, were chosen as representatives of all major pathogenicity groups and were genetically studied by AFLP. Eight primer combinations were utilized and approximately 300 scorable bands in total were generated. Based on similarity coefficient, E. amylovora strains were placed into a main cluster containing two sub clusters, indicating very low genetic variations among the studied pathogen. The existence of two plasmids, pEA29 (present in nearly all E. amylovora isolates) and pEL60 (present mainly in Lebanese strains), was confirmed using multiplex PCR in all tested Syrian E. amylovora strains, indicating that Lebanese and Syrian isolates may share a common origin.(author)

Detecting overweight and obesity among young Syrian boys based on skinfold thickness

Full Text Available There is no data on the prevalence of overweight and obesity in young Syrian boys. Therefore, the present study aimed to provide baseline and reference data on the prevalence of overweight and obesity among young Syrian boys using skin-fold thickness measurements and deuterium dilution (DD as a reference method. The sample of 2470 healthy Syrian 18- to 19-year-old boys were enrolled in this study. SFTs were measured at the biceps (B, triceps (T, subscapular (SI and suprailiac locations (SS were done and validated using the DD technique as a reference method. Receiver operating characteristics (ROC curve was drawn to determine appropriate cut-off points of the Σ2 limb SFT (T+B, Σ2 trunk SFT (SI+SS, Σ4 SFT (T+B+SI+SS and Log Σ4 SFT for defining overweight and obesity. The overall prevalence of overweight and obesity in young Syrian boys, based on biceps SFT, triceps SFT, subscapular SFT, suprailiac SFT, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT, logarithm Σ4 SFT, and DDT were 35.3%, 32%, 31.6%, 14.8%, 32.9%, 26.6%, 28.1%, 24.1%, 46.5%, respectively. Strongly positive correlation was found between SFT and total body fat in adolescents. For diagnosing overweight on the basis of Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT, we propose the following cut-off points: 17.25 mm, 23.50 mm, 39.25 mm and 1.60, respectively. To predict obesity, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT threshold were increased to 23.25 mm, 32.50 mm, 55.25 and 1.75, respectively. Basing on SFT clearly leads to underestimates of the prevalence of weight problems among young boys. SFT measurement screen missed 11.2 to 31.7% of overall overweight and obesity cases.

Radiation-induced anorexia in Syrian hamsters

Kindt, A.; Sattler, E.L.; Schraub, A.

1980-01-01

The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation. (orig.) [de

1995-01-01

A greenhouse pot experiment was conducted to evaluate the fertilizer use efficiency of three Syrian rock phosphates in comparison to Mussoorie rock phosphate from India for maize grown in a laterite (ultisol) and an alluvial (entisol) soil amended with sulphur, and using sup 3 sup 2 P-labelled triple superphosphate (TSP). Results showed that application of rock phosphates (RPs) to laterite soil significantly increased the dry matter yields of maize shoots, whereas, in alluvial soil, RPs were not found effective in increasing the yields. Data further indicated that all the three Syrian RPs were equally efficient in increasing dry matter yields in laterite soil and were superior to Mussoorie rock phosphate (MRP). Sulphur added in combination with RPs significantly enhanced the dry matter production as well as 'A' value of alluvial soil. Application of sulphur in conjunction with RPs significantly increased the 'A' value of laterite soil however, sulphur did not contribute to any significant increase in the yields. Syrian RPs were more reactive in soils than Mussoorie RP. (author). 7 refs., 6 tabs

Social context modulates food hoarding in Syrian hamsters

Directory of Open Access Journals (Sweden)

Bibiana Montoya

2016-09-01

Full Text Available The effect of the presence of a con-specific in the temporal organization of food hoarding was studied in two varieties of Syrian hamster (Mesocricetus auratus: golden and long-haired. Four male hamsters of each variety were used. Their foraging behavior was observed during four individual and four shared trials in which animals were not competing for the same food source or territory. During individual trials, long-haired hamsters consumed food items directly from the food source, transporting and hoarding only remaining pieces. During shared trials, the long-haired variety hoarded food items before consumption, and increased the duration of hoarding trips, food handling in the storage, and cache size. Golden hamsters maintained the same temporal organization of hoarding behavior (i.e., hoarding food items before consumption throughout both individual and shared trials. However, the golden variety increased handling time at the food source and decreased the duration of hoarding trips, the latency of hoarding and storing size throughout the shared trials. In Syrian hamsters, the presence of a con-specific may signal high probability of food source depletion suggesting that social pressures over food availability might facilitate hoarding behavior. Further studies are required to evaluate cost-benefit balance of food hoarding and the role of cache pilferage in this species.

Strange Animals and Creatures in Islamic Miniatures: Focusing on Miniatures of the Conference of the Birds

Directory of Open Access Journals (Sweden)

Neda Rohani

2017-09-01

Full Text Available Strange animals and creatures have always existed in every mythological culture. In Iran's pre-Islamic and post-Islamic miniatures and reliefs, there are many strange animals and creatures such as dragons and phoenix which were associated with the Iranian culture and civilization. Because of presence of these strange creatures, particularly human life, these creatures are first used in mythological life and then symbolically to express human ideas. However, these animals were present in both mythology and epics and, later in the Islamic era, in the mystical stories, educational stories and admonishing anecdotes like Sanai, Attar, and Rumi. This study tends to investigate genealogy of strange animals and creatures in ancient Iranian reliefs and their continued presence in miniatures of Islamic era as well as presence of these creatures in miniatures which are based on Attar’s Conference of the Birds. In fact, this study reviews elements and symbolic concepts of animals, allowing a deeper understanding of function of elements and symbolism in works of Iranian miniaturists. Contemplation of miniatures, icons and the relationship between literature and miniatures will lead to many results in recognition of mystical intellectual foundations. Therefore, this study tends to investigate mysterious and unknown aspects of Iranian miniatures and find their relationship with culture and stories.

Building upon social psychological work on social identity and mental health, this study among Syrian refugees in Turkey examined the importance of multiple group memberships and identity continuity for mental health and well-being. A survey study was conducted among the very difficult to reach population of Syrian refugees (N = 361). With path analysis in AMOS the associations were examined between multiple group memberships, social identity continuity and mental health and psychological well-being. Indicate that belonging to multiple groups before migration was related to a higher likelihood of having preserved group memberships after migration (i.e., sense of social identity continuity), which, in turn, predicted greater life satisfaction and lower levels of depression. Multiple group membership, however, was also directly related to higher depression. Findings are discussed in relation to the importance of multiple group membership and feelings of identity continuity for refugees.

Since the Syrian civil war began in 2011, most of the Syrian refugees have immigrated to Turkey due to its open gate policy and the width of the border. By the end of 2015, it was estimated that there were 2.5 million Syrian refugees in Turkey. Many of the Syrian refugees live in Sanliurfa due to its location on the border with Syria. Trichomonas vaginalis, apart from viral agents is the most common parasite among sexually transmitted infection agents. The aim of this study was to determine the prevalence of T.vaginalis among female married Syrian refugees living outside of the camps in Sanliurfa city center, aged between 15-49 years with complaints of vaginitis. This multi-purpose survey was carried out between February and March of 2015, in collaboration with the United Nations Population Fund and Harran University. This study was approved under the heading of "General Health Status of Female Syrian Refugees" by the Ethics Committee of Harran University Faculty of Medicine. A total of 460 Syrian refugees house were selected using the probability cluster sampling method, with a 95% confidence level and a 5% confidence interval with a design effect. Two women refused to participate in the study, and the response rate was 99.6%. Two Syrian nurses, one laboratory technician, and one interpreter who knew Kurdish and Arabic were hired for the field survey. A structured questionnaire written in Turkish was translated to Arabic and used to collect the sociodemographic data during face to face interviews. According to the questionnaire data, the women with the complaints of vaginal discharge, unusual vaginal bleeding and/or dyspareunia were invited to the Gynecology Department of Harran University Research and Training Hospital for a medical examination. During gynecological examination, swab samples obtained from posterior fornix were evaluated by direct microscopy and Giemsa staining methods for the presence of T.vaginalis trophozoites.

Full Text Available In recent years, a lot of demonstrations of the miniaturized instruments were reported for genomic applications. They provided the advantages of miniaturization, automation, sensitivity, and specificity for the development of point-of-care diagnostics. The aim of this paper is to report on recent developments on miniaturized instruments for genomic applications. Based on the mature development of microfabrication, microfluidic systems have been demonstrated for various genomic detections. Since one of the objectives of miniaturized instruments is for the development of point-of-care device, impedimetric detection is found to be a promising technique for this purpose. An in-depth discussion of the impedimetric circuits and systems will be included to provide total consideration of the miniaturized instruments and their potential application towards real-time portable imaging in the “-omics” era. The current excellent demonstrations suggest a solid foundation for the development of practical and widespread point-of-care genomic diagnostic devices.

2017-12-01

Full Text Available Lebanon is characterised by a touristic industry, making of it the highest touristic destination in the Arab world before 1975, the year in which Lebanon's civil war has erupted, a war from which Lebanon still suffers until now. Moreover, Lebanon suffers from internal political conflicts and the repercussions of the geopolitical conflicts in the Middle East, the latest of which is the Syrian war. While the crises in Lebanon prevail- from political, security, economic, social to even environmental - Lebanese policymakers are still seeking to make out of Lebanon a country considered as a touristic one, and are working on achieving a sustainable touristic development. In this context, this study tackles the crisis that Lebanon is experiencing as a result of forced Syrian displacement into its territory, and sheds light on its negative and positive effects on Lebanese tourism. The study also aims to determine the effectiveness of sustainable tourism development in times of crisis, based on the study of Lebanese touristic data during a specific period of time.

The Syrian armed conflict has been ongoing since 2011 and has already caused thousands of deaths. The analysis of death tolls helps to understand the dynamics of the conflict and to better allocate resources and aid to the affected areas. In this article, we use information on the daily number of deaths to study temporal and spatial correlations in the data, and exploit this information to forecast events of deaths. We found that the number of violent deaths per day in Syria varies more widely than that in England in which non-violent deaths dominate. We have identified strong positive auto-correlations in Syrian cities and non-trivial cross-correlations across some of them. The results indicate synchronization in the number of deaths at different times and locations, suggesting respectively that local attacks are followed by more attacks at subsequent days and that coordinated attacks may also take place across different locations. Thus the analysis of high temporal resolution data across multiple cities makes it possible to infer attack strategies, warn potential occurrence of future events, and hopefully avoid further deaths.

1990-01-01

The effectiveness of gamma-irradiation with dose rate8 X 10 -2 and 7 X 10 -3 Gy/min was determined. The translocation yield in Syrian hamster spermatogonia was used as index of genetic injury. The results obtained allowed to determine the RBE of the tested dose rate of photon radiation ti 0.8 and 0.4, respectively for 8 x 10 -2 and 7 x 10 -3 Gy/min. In contrast to mice and rats, under the same exposure conditions the mutation rate in Syrian hamsters showed a gradual decline with reducing the emissive power, without sharp changes. The reduction of the extent of genetic injury was also less abrupt. These results once more point to the importance of the mammalian species being used, regarding the manifestation of the effect of the dose rate. 1 fig., 2 tabs., 25 refs

Treating patients with care and respecting their cultural values are key factors necessary to enhance the quality of nursing care. The objective of this study was to explore and describe the difficulties experienced by hospitalized Syrian refugees and their expectations from nurses and hospital administration. We used a descriptive qualitative research approach to engage 30 Syrian refugees undergoing treatment in internal medicine who met the study criteria. Data were collected using a descriptive questionnaire and a semi-structured interview with open-ended interview questions. Interview transcripts were analysed using an inductive coding approach. Descriptive questions were analysed and presented via number and percentage. Other data were assessed using content analysis methods. Three major themes were developed following the analysis of the interviews. We determined that the refugees who participated in the study experienced difficulties in communicating, meeting their personal needs and correctly following treatment instructions. They also had certain expectations from the hospital administration and nurses, and they felt gratitude for both nurses and the nation of Turkey. The results of this study, shared with the executive administration of the hospital, may result in new policies which will help new Syrian refugee patients and patients with similar needs to have better experience related to patient care, communications and meeting personal needs. It is important that nurses and other healthcare provider consider the difficulties and expectations of refugees regarding healthcare services and include same in the development of provider training programmes. Development of public health welfare and employment law and policies help to lay the groundwork for successful integration of refugees in new cultures and countries. © 2016 International Council of Nurses.

Doganay, Mehmet; Demiraslan, Hayati

2016-01-01

After the Arab Spring uprising, Syria descended into a civil war in 2011. By March 2016, the United Nations reported that 13.5 million Syrians required humanitarian assistance, including 6.6 million internally displaced persons and more than 4.8 million refugees outside of Syria. Turkey is currently hosting the largest number of Syrian refugees-more than 2.7 million. A limited number of refugees are living in camps settled around the border, and others are spread throughout Turkey. This explosive and unexpected increase in the Syrian population in Turkey has had several negative impacts on health and social determinants. The overload of healthcare facilities has led to shortages in childhood immunization programs, drugs, and access to clean water and food supplies. According to Ministry of Health data, more than 7.5 million Syrians were examined at outpatient clinics, and 299,240 were hospitalized; most of those hospitalized were injured and wounded victims who require and have been occupying intensive care units. The refugees generally live in crowded and unsanitary conditions, which may lead to the spread of respiratory, skin, gastrointestinal, and genital system infections. Currently, measles, poliomyelitis, leishmaniasis, and multidrug-resistant tuberculosis are the reemerging infections being most frequently recorded. Multidrug-resistant gram-negative bacterial infections seem to be an increasing problem in gunshot or surgical wounds. Hepatitis A, malaria, and varicella have been seen with a high incidence among the refugees. There are many problems waiting to be resolved for health and living standards in Turkey.

Canada welcomed 33 723 Syrian refugees between November 2015 and November 2016. This paper reports the results of a rapid assessment of health care needs and use of health care services among newly arrived Syrian refugees in Toronto. A cross-sectional study was conducted in Toronto among Syrian refugees aged 18 years or more who had been in Canada for 12 months or less. Participants were recruited initially through distribution of flyers in hotels and through direct referrals and communication with community and settlement agency partners, and then through snowball sampling. We collected sociodemographic information and data on self-perceived physical health and mental health, unmet health care needs and use of health care services. A total of 400 Syrian refugees (221 women [55.2%] and 179 men [44.8%]) were enrolled. Of the 400, 209 (52.2%) were privately sponsored refugees, 177 (44.2%) were government-assisted refugees, and 12 (3.0%) were refugees under the Blended Visa Office-Referred Program. They reported high levels of self-perceived physical and mental health. Over 90% of the sample saw a doctor in their first year in Canada, and 79.8% had a family doctor they saw regularly. However, almost half (49.0%) of the respondents reported unmet health care needs, with the 3 most common reasons reported being long wait times, costs associated with services and lack of time to seek health care services. Many factors may explain our respondents' high levels of self-perceived physical and mental health during the first year of resettlement, including initial resettlement support and eligibility for health care under the Interim Federal Health Program. However, newly arrived Syrian refugees report unmet health care needs, which necessitates more comprehensive care and management beyond the initial resettlement support.

1991-01-01

The effects of neutron irradiation on the steel reactor vessel for the modular high-temperature gas-cooled reactor (MHTGR) are being investigated, primarily because the operating temperatures are low [121 to 210 degrees C (250--410 degrees F)] compared to those for commercial light-water reactors (LWRs) [∼288 degrees C (550 degrees F)]. The need for design data on the reference temperature shift necessitated the irradiation at different temperatures of A 533 grade B class 1 plate. A 508 class 3 forging, and welds used for the vessel shell, vessel closure head, the vessel flange. This paper presents results from the first four irradiation capsules of this program. The four capsules were irradiated in the University of Buffalo Reactor to an effective fast fluence of 1 x10 18 neutron/cm 2 [0.68 x 10 18 neutron/cm 2 (>1 MeV)] at temperatures of 288, 204, 163, and 121 degrees C (550, 400, 325, and 250 degrees F), respectively. The yield and ultimate strengths of both steel plate materials of the MHTGR Program increased with decreasing irradiation temperature. Similarly, the 41-J Charpy V-notch (CVN) transition temperature shift increased with decreasing irradiation temperature (in agreement with the increase in yield strength). The miniature tensile and automated ball indentation (ABI) test results (yield strength and flow properties) were in good agreement with those from standard tensile specimens. The miniature tensile and ABI test results were also used in a model that utilizes the changes in yield strength to estimate the CVN ductile-to-brittle transition temperature shift due to irradiation. The model predictions were compared with CVN test results obtained here and in earlier work. 5 refs., 11 figs., 6 tabs

2014-12-01

The vitamin D endocrine system regulates bone metabolism and calcium homeostasis as well as cellular proliferation and differentiation. Vitamin D receptor (VDR) mediates Vit-D activity, thus VDR gene polymorphisms may correlate with different diseases. This study aimed to determine the distribution of VDR gene (Taq-I and Apa-I) polymorphisms using a RFLP in unrelated normal healthy individuals of Syrian population. Allelic frequencies were 65% vs 35% and 66% vs 34% for T vs t and A vs a alleles, respectively. Genotype distribution was 36%, 58% and 6% for TT, Tt and tt and 42%, 47% and 10% for AA, Aa and aa, respectively. These results demonstrate that the frequency and distribution of the VDR polymorphisms in Syrian population are different from other populations worldwide.

2017-02-01

Cutaneous leishmaniasis (CL) is an important public health problem with around 2.000 autochthonous reported cases each year in Turkey. Due to the civil war in Syria, Turkey received around three million refugees and they are mainly located at either camps or homes in south/southeastern part of Turkey. In the present study, we aimed to collect samples from CL suspected patients admitting to State Hospital in Gaziantep City and perform parasitological and DNA-based techniques for diagnosis as well as species identification of the parasite for better understanding the prevalence of each species among Turkish and Syrian patients in the region. The collection of samples was carried out between January 2009 and July 2015. The lesion aspiration samples were taken and stained with Giemsa stain followed by microscopical examination for parasitological diagnosis. After the DNA extraction from Giemsa stained slides, real time and semi-nested PCRs both targeting ITS1 region were performed for molecular diagnosis and species identification. A total of 567 people were admitted to the hospital with the suspicion of CL and 263 (46.4%) of them were found to be positive by parasitological examination. One hundred seventy-four (66.15%), 88 (33.46%) and 1 (0.38%) of them were Turkish, Syrians and Afghan, respectively. Slide samples obtained from 34 CL suspected patients were analyzed by PCR and 20 of them were found positive. Eighteen (13 Turkish and 13 Syrians) of the positive samples were identified as L. tropica, while two (1 Turkish and 1 Syrian) of them were L. infantum. In conclusion, the effects of Syrian civil war on the epidemiology of CL in Gaziantep city is demonstrated in the present study. The use of molecular tool in the diagnosis of leishmaniasis is effective, sensitive and time saving which will enable the species typing. Species typing of the causative agent in endemic areas will bring valuable data to epidemiological knowledge. Copyright © 2016 Elsevier B.V. All

Highlights: • We carried out a CFD study to investigate transient natural convection in MNSR. • We applied porous media approach to simplify the complex core of MNSR. • Method have been verified with experimental data. • Temperature difference between the core inlet and outlet has been obtained. • Flow pattern and temperature distribution have been presented. - Abstract: The small and complex core of Isfahan Miniature Neutron Source Reactor (MNSR) in addition to its large tank makes a parametric study of natural convection difficult to perform in aspects of time and computational resources. In this study, in order to overcome this obstacle the porous media approximation has been used. This numerical technique includes two steps, (a) calculation of porous media variables such as porosity and pressure drops in the core region, (b) simulation of natural convection in the reactor tank by assuming the core region as a porous medium. Simulation has been carried out with ANSYS FLUENT® Academic Research, Release 16.2. The core porous medium resistance factors have been estimated to be, D{sub ij} = 1850 [1/m] and C{sub ij} = 415 [1/m{sup 2}]. Natural Convection simulation with Boussinesq approximation and variable property assumption have been performed. The experimental data and nuclear codes available in the literature, have verified the method. The average temperature difference between the experimental data and this study results was less than 0.5 °C and 2.0 °C for property variable technique and Boussinesq approximation, respectively. Temperature distribution and flow pattern in the entire reactor have been obtained. Results have shown that the temperature difference between core outlet and inlet is about 18°C and in this situation flow rate is about 0.004 kg/s. A full parametric study could be the topic of future investigations.

Neuropsychiatric disorders among Syrian and Iraqi refugees in Jordan: a retrospective cohort study 2012-2013.

The burden of neuropsychiatric disorders in refugees is likely high, but little has been reported on the neuropsychiatric disorders that affect Syrian and Iraqi refugees in a country of first asylum. This analysis aimed to study the cost and burden of neuropsychiatric disorders among refugees from Syria and Iraq requiring exceptional, United Nations-funded care in a country of first asylum. The United Nations High Commissioner for Refugees works with multi-disciplinary, in-country exceptional care committees to review refugees' applications for emergency or exceptional medical care. Neuropsychiatric diagnoses among refugee applicants were identified through a retrospective review of applications to the Jordanian Exceptional Care Committee (2012-2013). Diagnoses were made using International Classification of Disease-10(th) edition codes rendered by treating physicians. Neuropsychiatric applications accounted for 11% (264/2526) of all Exceptional Care Committee applications, representing 223 refugees (40% female; median age 35 years; 57% Syrian, 36% Iraqi, 7% other countries of origin). Two-thirds of neuropsychiatric cases were for emergency care. The total amount requested for neuropsychiatric disorders was 925,674 USD. Syrian refugees were significantly more likely to request neurotrauma care than Iraqis (18/128 vs. 3/80, p = 0.03). The most expensive care per person was for brain tumor (7,905 USD), multiple sclerosis (7,502 USD), and nervous system trauma (6,466 USD), although stroke was the most frequent diagnosis. Schizophrenia was the most costly and frequent diagnosis among the psychiatric disorders (2,269 USD per person, 27,226 USD total). Neuropsychiatric disorders, including those traditionally considered outside the purview of refugee health, are an important burden to health among Iraqi and Syrian refugees. Possible interventions could include stroke risk factor reduction and targeted medication donations for multiple sclerosis, epilepsy, and

Between international donors and local faith communities: Intermediaries in humanitarian assistance to Syrian refugees in Jordan and Lebanon.

2018-06-12

This paper explores the crucial part that faith-based organisations (FBOs) play in acting as intermediaries between international donors and local faith communities (LFCs) implementing humanitarian relief projects for Syrian refugees. Humanitarian responses to the mounting Syrian refugee crisis have coincided with greater collaboration between international donors and LFCs. This cooperation often is facilitated by a complex web of non-state intermediaries at the international, national, and local level. This study probes the breadth of roles of these intermediaries, drawing on primary data from case studies of two Christian intermediaries supporting Christian LFCs as they deliver aid primarily to Muslim Syrian refugees in Jordan and Lebanon. The results of the study are connected to the wider literature on LFCs in humanitarian response, revealing how intermediaries address issues of accountability, capacity-building, impartiality, neutrality, and professionalism. The paper concludes by offering suggestions for further research on intermediaries as key actors in the localisation of humanitarian assistance. © 2018 The Author(s).

Purpose: Peripheral dose in radiotherapy treatments represents a potential source of secondary neoplasic processes. As in the last few years, there has been a fast-growing concern on neutron collateral effects, this work focuses on this component. A previous established methodology to estimate peripheral neutron equivalent doses relied on passive (TLD, CR39) neutron detectors exposed in-phantom, in parallel to an active [static random access memory (SRAMnd)] thermal neutron detector exposed ex-phantom. A newly miniaturized, quick, and reliable active thermal neutron detector (TNRD, Thermal Neutron Rate Detector) was validated for both procedures. This first miniaturized active system eliminates the long postprocessing, required for passive detectors, giving thermal neutron fluences in real time. Methods: To validate TNRD for the established methodology, intrinsic characteristics, characterization of 4 facilities [to correlate monitor value (MU) with risk], and a cohort of 200 real patients (for second cancer risk estimates) were evaluated and compared with the well-established SRAMnd device. Finally, TNRD was compared to TLD pairs for 3 generic radiotherapy treatments through 16 strategic points inside an anthropomorphic phantom. Results: The performed tests indicate similar linear dependence with dose for both detectors, TNRD and SRAMnd, while a slightly better reproducibility has been obtained for TNRD (1.7% vs 2.2%). Risk estimates when delivering 1000 MU are in good agreement between both detectors (mean deviation of TNRD measurements with respect to the ones of SRAMnd is 0.07 cases per 1000, with differences always smaller than 0.08 cases per 1000). As far as the in-phantom measurements are concerned, a mean deviation smaller than 1.7% was obtained. Conclusions: The results obtained indicate that direct evaluation of equivalent dose estimation in organs, both in phantom and patients, is perfectly feasible with this new detector. This will open the door to an

Studying mental and physical health problems in refugees facilitates providing suitable health care, thus improving their quality of life. We studied depression tendency in Syrian refugees in Jordan in the light of chronic diseases and medication availability. Also, depression prevalence and depression comorbidity with chronic diseases were identified. In this multicenter cross-sectional survey, data from Syrian refugees attending Caritas centers in 6 Jordanian cities from November 2013 through June 2014 were analyzed. Participants' demographics, depression, previously diagnosed chronic diseases, and newly diagnosed chronic diseases and the availability of medications were studied. Logistic regression was used to examine predictors for depression. Of 765 refugees who participated, about one-third demonstrated significant depression as measured by the Beck Depression Inventory. Descriptive analyses showed that depression was comorbid in 35% of participants with previously diagnosed chronic diseases and in 40% of participants with newly diagnosed chronic diseases. Newly diagnosed chronic diseases and lack of medications significantly contributed to depression, but the regression model as a whole explained less than 5% of the variance. Because the regression model showed low effect size, we concluded that newly diagnosed chronic diseases and medication shortages could not predict depression in Syrian refugees residing in Jordan. Therefore, further studies of additional factors are recommended. Prompt measures have to be taken to prevent the spread of chronic diseases and improve mental health in this fragile population.

Congenital cataracts and microphthalmia in the Miniature Schnauzer were inherited as an autosomal recessive trait. Eighteen matings of affected X affected Miniature Schnauzers resulted in 87 offspring with congenital cataracts and microphthalmia (49 males/38 females). Two matings of congenital cataractous and microphthalmic Miniature Schnauzers (2 females) X a normal Miniature Schnauzer (1 male) yielded 11 clinically normal Miniature Schnauzers (7 males/4 females). Eighteen matings of congenital cataractous and microphthalmic Miniature Schnauzers (6 males) X carrier Miniature Schnauzers (9 females) produced 81 offspring; 39 exhibited congenital cataracts and microphthalmia (20 males/19 females) and 42 had clinically normal eyes (17 males/25 females).

Obesity has become a serious epidemic health problem in both developing and developed countries. There is much evidence that obesity among adolescents contributed significantly to the development of type 2 diabetes and coronary heart disease in adulthood. Very limited information exists on the prevalence of overweight, obesity, and associated metabolic risk factors among Syrian adolescents. Therefore, the purpose of this study was to determine the relationship between obesity determined by body mass index and the major metabolic risk factors among Syrian adolescents. A cross-sectional study of a randomly selected sample of 2064 apparently healthy Syrian adolescents aged 18 to 19 years from Damascus city, in Syria, was performed. Body mass index and blood pressure were measured. Serum concentrations of glucose, triglycerides, total cholesterol, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol were determined. Metabolic syndrome was defined using the national criteria for each determined metabolic risk factor. Individuals with a body mass index 25 to 29.9 were classified as overweight, whereas individuals with a body mass index ≥30 were classified as obese. A receiver operating characteristics curve was drawn to determine appropriate cut-off points of the body mass index for defining overweight and obesity, and to indicate the performance of body mass index as a predictor of risk factors. The obtained data showed that blood pressure and the overall mean concentrations of fasting blood sugar, triglycerides, cholesterol, low-density lipoprotein-cholesterol, and triglycerides/high-density lipoprotein-cholesterol were significantly higher in overweight and obese adolescent groups (p index and some metabolic risks, the data suggest the best body mass index cut-offs ranged between 23.25 and 24.35 kg/m 2 .

C-reactive protein (CRP) is a sensitive marker for inflammation in people and dogs. In people, an association between CRP concentration and atherosclerosis has been reported. Atherosclerosis is rare in dogs, but the Miniature Schnauzer breed may be at increased risk for developing this vascular disease. It is not known if CRP concentrations in Miniature Schnauzer dogs differ from those in other dog breeds. Our objectives were to validate an automated human CRP assay for measuring CRP in dogs and compare CRP concentrations in healthy Miniature Schnauzer dogs with those in non-Miniature Schnauzer breeds. Sera from 37 non-Miniature Schnauzer dogs with inflammatory disease were pooled and used to validate a human CRP immunoturbidimetric assay for measuring canine CRP. Blood was collected from 20 healthy Miniature Schnauzer dogs and 41 healthy dogs of other breeds. Median serum CRP concentration of healthy Miniature Schnauzer dogs was compared with that of healthy non-Miniature Schnauzer dogs. The human CRP assay measured CRP reliably with linearity between 0 and 20 mg/L. CRP concentration for healthy Miniature Schnauzer dogs (median 4.0 mg/L, minimum-maximum 0-18.2 mg/L) was significantly higher than for the healthy non-Miniature Schnauzer dogs (median 0.1 mg/L, minimum-maximum 0-10.7 mg/L); 17 of the 20 Miniature Schnauzer dogs had values that overlapped with those of the non-Miniature Schnauzer dogs. Median CRP concentration of Miniature Schnauzer dogs was slightly higher than that of other breeds of dogs. A relationship between higher CRP concentration in Miniature Schnauzer dogs and idiopathic hyperlipidemia, pancreatitis, and possible increased risk for atherosclerosis remains to be determined. ©2011 American Society for Veterinary Clinical Pathology.

There is a need for Municipal Solid Waste (MSW) stream characterization and composition analysis to allow for an accurate estimation of its recycling potential and for effective management of the entire system. Recycling provides employment and a livelihood for vulnerable social groups such as refugees. The aim of this paper is to determine the composition of MSW in Zaatari Syrian Refugee Camp, where approximately 430,000 Syrian refugees have passed through the camp. The representative waste samples and analysis included household waste and commercial waste produced by the refugees in the selected districts in Zaatari. The waste sampling was performed in 2015 over two seasons to ensure that the seasonal fluctuations in the composition of the waste stream are taken into consideration. Hand sorting was used for classifying the collected wastes into the categories and subcategories. The organic waste represents the main waste category with 53% of the total MSW, while plastics, textile, and paper and cardboard are 12.85%, 10.22% and 9%, respectively. Moreover, the MSW composition percentage in Zaatari Camp is similar to that in municipalities in Jordan with slight disparity. The potential recyclable materials market has been investigated in this study. Plastics and paper and cardboard have significant potential to be separated and collected for recycling purposes. Financial revenues of potential recyclables have been analyzed based on local prices. Recycling model in the camp is also proposed based on the present study findings. Consequently, these results should be taken as a baseline for all Syrian refugees camps in the Middle East, as well as, in Europe. Copyright © 2016 Elsevier Ltd. All rights reserved.

Introduction: There are nearly 3 million Syrian refugees, with more than 1 million in Lebanon. We combined quantitative and qualitative methods to determine cesarean section (CS) rates among Syrian refugees accessing care through United Nations High Commissioner for Refugees (UNHCR)-contracted hospitals in Lebanon and possible driving factors. Methods: We analyzed hospital admission data from UNHCR’s main partners from December 2012/January 1, 2013, to June 30, 2013. We collected qualitative data in a subset of hospitals through semi-structured informant interviews. Results: Deliveries accounted for almost 50 percent of hospitalizations. The average CS rate was 35 percent of 6,366 deliveries. Women expressed strong preference for female providers. Clinicians observed that refugees had high incidence of birth and health complications diagnosed at delivery time that often required emergent CS. Discussion: CS rates are high among Syrian refugee women in Lebanon. Limited access and utilization of antenatal care, privatized health care, and male obstetrical providers may be important drivers that need to be addressed. PMID:25191143

Refugee women are almost five times more likely to develop postpartum depression than Canadian-born women. This can be attributed to various difficulties they faced before coming to Canada as well as during resettlement. Moreover, refugee women usually face many obstacles when accessing health services, including language and cultural barriers, as well as unique help-seeking behaviors that are influenced by various cultural and practical factors. There has been a recent, rapid influx of Syrian refugees to Canada, and many of them are childbearing women. However, little is known about the experiences that these women have encountered pre- and post-resettlement, and their perceptions of mental health issues. Thus, there is an urgent need to understand refugee women's experiences of having a baby in Canada from a mental health perspective. A mixed methods research design included 12 Syrian refugee women who migrated to Saskatoon in 2015-16 and who were either pregnant or 1 year postpartum. The data were collected during a single focus group discussion and a structured questionnaire. Our results showed that more than half of participants have depressive symptoms, half of them have anxiety symptoms, and one sixth have PTSD symptoms. Three major themes emerged from the qualitative data: 1) Understanding of maternal depression; 2) Protective factors for mental health; and 3) Barriers to mental health services. Maternal depression is an important feature in Syrian refugee women recently resettled in Canada. Reuniting these women with their families and engaging them in culturally appropriate support programs may improve their mental health outcomes.

Full Text Available The relationships between breadmaking quality, kernel properties (physical and chemical, and dough rheology were investigated using flours from six genotypes of Syrian wheat lines, comprising both commercially grown cultivars and advanced breeding lines. Genotypes were grown in 2008/2009 season in irrigated plots in the Eastern part of Syria. Grain samples were evaluated for vitreousness, test weight, 1000-kernel weight and then milled and tested for protein content, ash, and water content. Dough rheology of the samples was studied by the determination of the mixing time, stability, weakness, resistance and the extensibility of the dough. Loaf baking quality was evaluated by the measurement of the specific weight, resilience and firmness in addition to the sensory analysis. A comparative study between the six Syrian wheat genotypes and two English flour samples was conducted. Significant differences were observed among Syrian genotypes in vitreousness (69.3%–95.0%, 1000-kernel weight (35.2–46.9 g and the test weight (82.2–88.0 kg/hL. All samples exhibited high falling numbers (346 to 417 s for the Syrian samples and 285 and 305 s for the English flours. A significant positive correlation was exhibited between the protein content of the flour and its absorption of water (r = 0.84 **, as well as with the vitreousness of the kernel (r = 0.54 *. Protein content was also correlated with dough stability (r = 0.86 **, extensibility (r = 0.8 **, and negatively correlated with dough weakness (r = −0.69 **. Bread firmness and dough weakness were positively correlated (r = 0.66 **. Sensory analysis indicated Doumah-2 was the best appreciated whilst Doumah 40765 and 46055 were the least appreciated which may suggest their suitability for biscuit preparation rather than bread making.

1999-01-01

Neutronics analysis of both MNSR and Slowpoke reactors were made. Calculations including flux distribution, power estimation, excess and shutdown reactivity margins, flooding effects of irradiation sites, and initial investigation of fuel conversion from high to low enriched uranium were discussed. A neutronic 3-D model, dedicated mainly for the MNSR, has been developed to perform such neutronic calculations for both reactors. Well-known cell and core calculation codes such as WIMSD4 and CITATIONS have been used. It was found out that it is possible to lower the fuel enrichment of the Miniature Neutron Source Reactor (MNSR) to 20% using U O 2 as fuel instead of U Al 4 . The number of fuel elements required for the new core is 199. The use of double thickness of the bottom reflector in Slowpoke reactor made it possible to load the reactor with lower enriched fuel compared to MNSR. Values of reactivity flooding effects for single or combination of inner irradiation sites were obtained accurately. Results show good agreement with reported data for MNSR. (author)

Feasibility studies on the production of essential radioisotopes (24Na and 32P) using the Ghana Miniature Neutron Source Reactor (GHARR-1)

Dotse, S.C.

2012-01-01

Feasibility studies on the production of 32 P and 24 Na using a Miniature Neutron Source Reactor named Ghana Research Reactor-1 (GHARR-1) has been conducted. A theoretical model of the cyclic activation technique was developed for the simulation of specific activities under varying parameters. Specific activity values estimated for four cycles of irradiation with activation parameters falling within the specifications of the reactor were experimentally validated. Experimented results were compared to those theoretically estimated for both 24 Na and 32 P. Experimented specific activity values for both radioisotopes generally fell below their theoretical values but recorded activity build-ups from one cycle to the other. The 24 Na nuclide showed a regular pattern for the increase in specific activity from one cycle to the next with an average percentage difference of experimented to theoretical value of 19%. The 32 P nuclide showed an irregular pattern for the increase in specific activity from one cycle to the next with an average percentage difference of experimental to theoretical value of 11%. The specific activities experimentally attained, with reference to activity levels used for various applications in agriculture and industry suggests the cyclic activation technique can be used for the production of radioisotopes of appreciable activities using low power research reactors, which are characterised with limited excess core reactivity and cannot sustain long periods of irradiation.

For two years the State of Israel has been treating casualties from the Syrian civil war. The Galilee Medical Center in Nahariya is the main hospital for this humanitarian mission. Objectives: To evaluate the demographic and clinical characteristics of the casualties that were treated in our department. Information from medical records of all Syrian casualties evacuated to the Galilee Medical Center were evaluated. Between March 2013 and December 2014, 450 casualties were evacuated to the Galilee Medical Center. Of those, 45 were treated in the Department of Otolaryngology - Head and Neck Surgery. Of the 45 cases, 43 were male (95.5%) and the mean age was 30.4 years (range 1-79 years). There was a significant difference in terms of gender (p Syria, and 12 died. Of all Syrian injured treated in the ENT department, the vast majority were young men. The main cause of injury was gunshot wounds. It is likely that the lack of protective gear that exist in western armies is a factor in the complex injuries treated at the Galilee Medical Center.

2015-01-01

This study examined intra- and interindividual variations in parental legitimacy beliefs in a sample of 883 Arab refugee adolescents (M(age) = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians in Amman, Jordan. Confirmatory factor analyses showed distinct latent factors for moral-conventional, prudential, and personal legitimacy items. Older adolescents rated legitimacy lower for personal issues, but higher for prudential issues. Beliefs were associated with socioeconomic status (fathers' education, family size), particularly for personal issues, but were more pervasively associated with displacement-related experiences. Greater war trauma was associated with less prudential legitimacy for all youth and more authority legitimacy over moral-conventional issues for Syrian youth. Greater hopefulness was associated with more authority legitimacy over all but personal issues. © 2015 The Authors. Child Development © 2015 Society for Research in Child Development, Inc.

Exploiting social media for Army operations: Syrian crisis use case

Science.gov (United States)

Kase, Sue E.; Bowman, Elizabeth K.; Al Amin, Tanvir; Abdelzaher, Tarek

2014-05-01

Millions of people exchange user-generated information through online social media (SM) services. The prevalence of SM use globally and its growing significance to the evolution of events has attracted the attention of the Army and other agencies charged with protecting national security interests. The information exchanged in SM sites and the networks of people who interact with these online communities can provide value to Army intelligence efforts. SM could facilitate the Military Decision Making Process by providing ongoing assessment of military actions from a local citizen perspective. Despite potential value, there are significant technological barriers to leveraging SM. SM collection and analysis are difficult in the dynamic SM environment and deception is a real concern. This paper introduces a credibility analysis approach and prototype fact-finding technology called the "Apollo Fact-finder" that mitigates the problem of inaccurate or falsified SM data. Apollo groups data into sets (or claims), corroborating specific observations, then iteratively assesses both claim and source credibility resulting in a ranking of claims by likelihood of occurrence. These credibility analysis approaches are discussed in the context of a conflict event, the Syrian civil war, and applied to tweets collected in the aftermath of the Syrian chemical weapons crisis.

Kidney size may be altered in renal diseases, and the detection of kidney size alteration has diagnostic and prognostic values. We hypothesized that radiographic kidney size, the kidney length to the second lumbar vertebra (L2) length ratio, in normal Miniature Schnauzer dogs may be overestimated due to their shorter vertebral length. This study was conducted to evaluate radiographic and ultrasonographic kidney size and L2 length in clinically normal Miniature Schnauzers and other dog breeds to evaluate the effect of vertebral length on radiographic kidney size and to reestablish radiographic kidney size in normal Miniature Schnauzers. Abdominal radiographs and ultrasonograms from 49 Miniature Schnauzers and 54 other breeds without clinical evidence of renal disease and lumbar vertebral abnormality were retrospectively evaluated. Radiographic kidney size, in the Miniature Schnauzer (3.31 ± 0.26) was significantly larger than that in other breeds (2.94 ± 0.27). Relative L2 length, the L2 length to width ratio, in the Miniature Schnauzer (1.11 ± 0.06) was significantly shorter than that in other breeds (1.21 ± 0.09). However, ultrasonographic kidney sizes, kidney length to aorta diameter ratios, were within or very close to normal range both in the Miniature Schnauzer (6.75 ± 0.67) and other breeds (7.16 ± 1.01). Thus, Miniature Schnauzer dogs have breed-specific short vertebrae and consequently a larger radiographic kidney size, which was greater than standard reference in normal adult dogs. Care should be taken when evaluating radiographic kidney size in Miniature Schnauzers to prevent falsely diagnosed renomegaly.

THE PROBLEM OF SYRIAN REFUGEES IN EUROPE AND JOHN RAWLS'S THEORY OF JUSTICE

Full Text Available One of the painful problems of the current world reality is the situation of Syrian refugees, many of whom choose Europe as a destination. This migratory process is the result of a violent civil war, which devastates the population of Syria over the last six years. The Syrian conflict is part of an international scenario where geopolitical relations no longer behave as they were in the beginning of the process of globalization and human rights seek to survive as an essential instrument for maintaining civility. Thus, this study had as objective to analyze the questions around the migratory flow, in the light of the Theory of Justice of John Rawls, whose proposal alerts to the traps of the utilitarianism and preaches the cooperation between the human beings. As a response to the proposed comparison, it was observed the difficulty in extending the idea of justice, in the manner thought by Rawls, to the tension addressed, since the power of fraternity is precisely made.

This study revisited the prevalence of posttraumatic stress disorder (PTSD) and examined a hypothesized model describing the interrelationship between trauma exposure characteristics, trauma centrality, emotional suppression, PTSD, and psychiatric comorbidity among Syrian refugees. A total of 564 Syrian refugees participated in the study and completed the Harvard Trauma Questionnaire, General Health Questionnaire (GHQ-28), Centrality of Event Scale, and Courtauld Emotional Control Scale. Of the participants, 30% met the cutoff for PTSD. Trauma exposure characteristics (experiencing or witnessing horror and murder, kidnapping or disappearance of family members or friends) were associated with trauma centrality, which was associated with emotional suppression. Emotional suppression was associated with PTSD and psychiatric comorbid symptom severities. Suppression mediated the path between trauma centrality and distress outcomes. Almost one-third of refugees can develop PTSD and other psychiatric problems following exposure to traumatic events during war. A traumatized identity can develop, of which life-threatening experiences is a dominant feature, leading to suppression of depression with associated psychological distress.

  This study was undertaken to investigate whether a single G deletion within a series of seven G residues (codon 196) at the exon 9-intron 9 boundary of the enamelin gene ENAM and a tri-nucleotide deletion at codon 180 in exon 7 (GGA vs deletion) of ameloblastin gene AMBN could have a role in autosomal amelogenesis imperfecta among affected Syrian families.   A new technique - size-dependent, deletion screening - was developed to detect nucleotide deletion in ENAM and AMBN genes. Twelve Syrian families with autosomal-dominant or -recessive amelogenesis imperfecta were included.   A homozygous/heterozygous mutation in the ENAM gene (152/152, 152/153) was identified in affected members of three families with autosomal-dominant amelogenesis imperfecta and one family with autosomal-recessive amelogenesis imperfecta. A heterozygous mutation (222/225) in the AMBN gene was identified. However, no disease causing mutations was found. The present findings provide useful information for the implication of ENAM gene polymorphism in autosomal-dominant/-recessive amelogenesis imperfecta.   Further investigations are required to identify other genes responsible for the various clinical phenotypes. © 2010 Blackwell Publishing Asia Pty Ltd.

Small Scaffolds, Big Potential: Developing Miniature Proteins as Therapeutic Agents.

Science.gov (United States)

Holub, Justin M

2017-09-01

Preclinical Research Miniature proteins are a class of oligopeptide characterized by their short sequence lengths and ability to adopt well-folded, three-dimensional structures. Because of their biomimetic nature and synthetic tractability, miniature proteins have been used to study a range of biochemical processes including fast protein folding, signal transduction, catalysis and molecular transport. Recently, miniature proteins have been gaining traction as potential therapeutic agents because their small size and ability to fold into defined tertiary structures facilitates their development as protein-based drugs. This research overview discusses emerging developments involving the use of miniature proteins as scaffolds to design novel therapeutics for the treatment and study of human disease. Specifically, this review will explore strategies to: (i) stabilize miniature protein tertiary structure; (ii) optimize biomolecular recognition by grafting functional epitopes onto miniature protein scaffolds; and (iii) enhance cytosolic delivery of miniature proteins through the use of cationic motifs that facilitate endosomal escape. These objectives are discussed not only to address challenges in developing effective miniature protein-based drugs, but also to highlight the tremendous potential miniature proteins hold for combating and understanding human disease.

Asiello, Peter J; Baeumner, Antje J

2011-04-21

Micro-Total Analysis Systems (µTAS) for use in on-site rapid detection of DNA or RNA are increasingly being developed. Here, amplification of the target sequence is key to increasing sensitivity, enabling single-cell and few-copy nucleic acid detection. The several advantages to miniaturizing amplification reactions and coupling them with sample preparation and detection on the same chip are well known and include fewer manual steps, preventing contamination, and significantly reducing the volume of expensive reagents. To-date, the majority of miniaturized systems for nucleic acid analysis have used the polymerase chain reaction (PCR) for amplification and those systems are covered in previous reviews. This review provides a thorough overview of miniaturized analysis systems using alternatives to PCR, specifically isothermal amplification reactions. With no need for thermal cycling, isothermal microsystems can be designed to be simple and low-energy consuming and therefore may outperform PCR in portable, battery-operated detection systems in the future. The main isothermal methods as miniaturized systems reviewed here include nucleic acid sequence-based amplification (NASBA), loop-mediated isothermal amplification (LAMP), helicase-dependent amplification (HDA), rolling circle amplification (RCA), and strand displacement amplification (SDA). Also, important design criteria for the miniaturized devices are discussed. Finally, the potential of miniaturization of some new isothermal methods such as the exponential amplification reaction (EXPAR), isothermal and chimeric primer-initiated amplification of nucleic acids (ICANs), signal-mediated amplification of RNA technology (SMART) and others is presented.

The Middle East respiratory syndrome coronavirus (MERS-CoV does not replicate in Syrian hamsters.

Directory of Open Access Journals (Sweden)

Emmie de Wit

Full Text Available In 2012 a novel coronavirus, MERS-CoV, associated with severe respiratory disease emerged in the Arabian Peninsula. To date, 55 human cases have been reported, including 31 fatal cases. Several of the cases were likely a result of human-to-human transmission. The emergence of this novel coronavirus prompts the need for a small animal model to study the pathogenesis of this virus and to test the efficacy of potential intervention strategies. In this study we explored the use of Syrian hamsters as a small animal disease model, using intratracheal inoculation and inoculation via aerosol. Clinical signs of disease, virus replication, histological lesions, cytokine upregulation nor seroconversion were observed in any of the inoculated animals, indicating that MERS-CoV does not replicate in Syrian hamsters.

Pedro Fernandes

2010-03-01

Full Text Available The use of biocatalysts for the production of both consumer goods and building blocks for chemical synthesis is consistently gaining relevance. A significant contribution for recent advances towards further implementation of enzymes and whole cells is related to the developments in miniature reactor technology and insights into flow behavior. Due to the high level of parallelization and reduced requirements of chemicals, intensive screening of biocatalysts and process variables has become more feasible and reproducibility of the bioconversion processes has been substantially improved. The present work aims to provide an overview of the applications of miniaturized reactors in bioconversion processes, considering multi-well plates and microfluidic devices, update information on the engineering characterization of the hardware used, and present perspective developments in this area of research.

The effects of liquid storage at 15 degrees C on the fertilizing ability of miniature pig semen were investigated. Characterization of ejaculated semen from 3 miniature boars was carried out. Semen volume and pH were similar among these boars. In one of the boars, sperm motility was slightly low, and sperm concentration and total number of sperm were significantly lower than in the others (P semen was substituted with various extenders (Kiev, Androhep, BTS and Modena) by centrifugation and semen was stored for 7 days at 15 degrees C. Sperm motility was estimated daily at 37 degrees C. For complete substitution of seminal plasma, Modena was significantly more efficient than the other extenders (P Semen from each of the 3 miniature boars that had been stored for 5 to 7 days at 15 degrees C in Modena was used for artificial insemination of 15 miniature sows. The farrowing rates were 100, 100 and 60%, and litter sizes were 6.4 +/- 1.5, 5.8 +/- 0.8 and 5.0 +/- 1.0 for each boar semen, respectively. The boar that sired the smallest farrowing rate was the same one that showed lower seminal quality with respect to sperm motility, sperm concentration and total number of sperm. These results suggest that miniature boar semen can be stored for at least 5 days at 15 degrees C by the substitution of seminal plasma with Modena extender.

Furet, J.

1977-01-01

The aims of neutronic control instrumentation are briefly recalled and the present status of materials research and development is presented. As for the out-of-pile instrumentation, emphasis is put on the reliability and efficiency of the detectors and the new solutions of electric signal processing. The possible reactivity measurements at rest are examined. As for in-pile instrumentation results relating to mobile detectors of the type of miniaturized fission chambers are presented. The radiation tests on course of development for several years in the working conditions of neutron self-powdered detectors are analyzed so as to show that their use as built-in in-core instrumentation is to be envisaged at short term. Basic options inherent to the 'Nuclear Safety' philosophy that define the protection system are recalled. A definition and a justification of the performance testing of the instrumentation at rest and in-service are then derived. Some new solutions are envisaged for processing the digital data obtained from the various sensors . A quality control of the materials setting conditions (especially electric noise) ensures a high reliability and availability of the materials involved in the neutron control and the protection system in working conditions [fr

Refugees all over the world are facing several health-related problems. Chronic diseases among Syrian refugees in Jordan are high. The Home Medication Management Review (HMMR) service could be ideal to optimize refugees' health management. To assess the impact of the HMMR service on the type and frequency of Treatment Related Problems (TRPs) among Syrian refugees living in Jordan. This prospective randomized single blinded intervention-control study was conducted in three main cities in Jordan, between May and October 2016. Syrian refugees with chronic conditions were recruited and randomized into intervention and control groups. The HMMR service was conducted for all patients to identify TRPs at baseline. Data were collected via two home visits for all study participants. Clinical pharmacist's recommendations were written in a letter format to the physicians managing the patients in the intervention group only. Physicians' approved recommendations were conveyed to the patients via the pharmacist. Interventions at the patient level were delivered by the pharmacist directly. Patients were reassessed for their TRPs and satisfaction 3 months after baseline. Syrian refugees (n = 106) were recruited with no significant differences between the intervention (n = 53) and control groups (n = 53). A total of 1141 TRPs were identified for both groups at baseline, with a mean number of 10.8 ± 4.2 TRPs per patient. At follow-up, there was a significant decrease in the number of TRPs among the intervention group (P service. Identified TRPs are high amongst Syrian refugees living in Jordan. The HMMR service significantly reduced the number of TRPs, and was highly accepted by the physicians. Refugees reported high satisfaction with this service. Copyright © 2018.

Shlewit, H.; Alibrahim, M.

2007-01-01

Uranium concentrations were analyzed in the Syrian phosphate deposits. Mean concentrations were found between 50 and 110 ppm. As a consequence, an average phosphate dressing of 22 kg/ha phosphate would charge the soil with 5-20 g/ha uranium when added as a mineral fertilizer. Fine grinding phosphate produced at the Syrian mines was used for uranium recovery by carbonate leaching. The formation of the soluble uranyl tricarbonate anion UO 2 (CO 3 ) 3 4- permits use of alkali solutions of sodium carbonate and sodium bicarbonate salts for the nearly selective dissolution of uranium from phosphate. Separation of iron, aluminum, titanium, etc., from the uranium during leaching was carried out. Formation of some small amounts of molybdates, vanadates, phosphates, aluminates, and some complexes metal was investigated. This process could be used before the manufacture of TSP fertilizer, and the final products would contain smaller uranium quantities. (author)

Cutaneous leishmaniasis (CL), seen endemically in many countries, is a widespread protozoon disease all around the world. The neighboring countries of Turkey namely Iran, Iraq and Syria are highly endemic regions for CL, and more than 98% of the cases in Turkey are reported from South and Southeastern Anatolian regions. The aim of this study was to detect the prevalence of CL in Nizip, a district of Gaziantep province of southeastern Turkey, for three and half year period and to call attention to the dramatic increase of CL cases observed after the Syrian civil war. A total of 416 samples obtained from clinically suspected CL patients (of them 341 were Syrian refugees) who were admitted to Nizip State Hospital between January 1st 2010 and March 19th 2013 were included in the study. Lesion samples were collected according to the notice issued by Turkish Ministry of Health and Giemsa-stained smears were examined under the microscope (x1000). Samples from 77 patients (18.5%) yielded positive results with the observation of Leishmania amastigote forms. Fourty-seven (61%) of patients were female and 30 (39%) were male. Of the positive patients 52 (67.5%) belonged to 0-19 age group, 13 (16.9%) 20-39 and 12 (15.6%) 40-60 age groups. In the evaluation of the lesion characteristics, 33 (43%) patients had single and 44 (57%) had multiple lesions with a distribution mainly on face, arm and lower extremities, in a decreasing order. The period of time for the development of the lesions varied from 1.5 month to one year with the mean value of 3.4 months. There was no statistically significant relationship between the age and gender of patients, and the characteristics (quantity, distribution and time of occurence) of lesions (p> 0.05). The number of domestic and Syrian CL cases detected in Nizip in the years of 2010, 2011, 2012 and 2013 (the first three months) were as follows; 1 and 0, 2 and 0, 7 and 0, 5 and 62, respectively. So a total of 62 (80.5%) and 15 (19.5%) of CL

The small punch (SP) test as one of the useful small specimen testing technique (SSTT) has been developed to evaluate the fracture toughness, ductile-brittle transition temperature (DBTT) and tensile properties for neutron irradiated structural materials. The SP tests using the miniaturized specimens of φ3 mm TEM disk and 10 mm 2 coupon were performed for six kinds of ferritic steels of F-82, F-82H, HT-9, JFMS, 2.25-1Mo and SQV2A. It was shown that the temperature dependence of SP fracture energies with scatter in miniaturized testing can give reliable information on the DBTT by use of the statistical analysis based on the Weibull distribution. A good correlation between the DBTT of the SP tests and that of the standard CVN test has been obtained for the various nuclear ferritic steels. The SP test was performed for cryogenic austenitic steels as a way of evaluating elastic-plastic fracture toughness, J IC , on the basis of a universal empirical relationship between J IC and SP equivalent fracture strain, ε-bar qf . The SP testing using the neutron irradiated specimens of 2.25Cr-1Mo, F-82, F-82H and HT-9 steels was successfully applied and presented the neutron radiation induced changes on the DBTT, fracture toughness and tensile properties.

Wiegel, B

2002-01-01

The original Bonner sphere spectrometer as it is used and characterized by PTB consists of 12 polyethylene spheres with diameters from 7.62 cm (3'') to 45.72 cm (18'') and a sup 3 He-filled spherical proportional counter used as a central thermal-neutron-sensitive detector and as a bare or cadmium-shielded bare detector. In this paper, a set of four new spheres made of polyethylene with copper or lead inlets is introduced. All spheres are less than 18 kg in mass and their responses to high energy neutrons increase with energy as a result of the increasing (n,xn) cross-sections of copper and lead. The fluence response matrix was calculated up to 10 GeV using an extended neutron cross-section library (LA150) and the MCNP(X) Monte Carlo code. Calibration measurements with neutron energies up to 60 MeV were used to compare the calculated response functions to measured values. For measurements outside the laboratory, a miniaturized, battery-powered electronic set-up was developed. This system with the additional, ...

There are currently more people displaced by conflict than at any time since World War II. The profile of displaced populations has evolved with displacement increasingly occurring in urban and middle-income settings. Consequently, an epidemiological shift away from communicable diseases that have historically characterized refugee populations has occurred. The high prevalence of non-communicable diseases (NCDs) poses a challenge to in terms of provision of appropriate secondary and tertiary services, continuity of care, access to medications, and costs. In light of the increasing burden of NCDs faced by refugees, we undertook this study to characterize the prevalence of NCDs and better understand issues related to care-seeking for NCDs among Syrian refugees in non-camp settings in Jordan. A cross-sectional survey of 1550 refugees was conducted using a multi-stage cluster design with probability proportional to size sampling to obtain a nationally representative sample of Syrian refugees outside of camps. To obtain information on chronic conditions, respondents were asked a series of questions about hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and arthritis. Differences by care-seeking for these conditions were examined using chi-square and t-test methods and characteristics of interest were included in the adjusted logistic regression model. Among adults, hypertension prevalence was the highest (9.7%, CI: 8.8-10.6), followed by arthritis (6.8%, CI: 5.9-7.6), diabetes (5.3%, CI: 4.6-6.0), chronic respiratory diseases (3.1%, CI: 2.4-3.8), and cardiovascular disease (3.7%, CI: 3.2, 4.3). Of the 1363 NCD cases, 84.7% (CI: 81.6-87.3) received care in Jordan; of the five NCDs assessed, arthritis cases had the lowest rates of care seeking at 65%, (CI:0-88, p = 0.005). Individuals from households in which the head completed post-secondary and primary education, respectively, had 89% (CI: 22-98) and 88% (CI: 13-98) lower odds of seeking care

Miniaturization and cost reduction of spectrometer and sensor technologies has great potential to open up new applications areas and business opportunities for analytical technology in hand held, mobile and on-line applications. Advances in microfabrication have resulted in high-performance MEMS and MOEMS devices for spectrometer applications. Many other enabling technologies are useful for miniature analytical solutions, such as silicon photonics, nanoimprint lithography (NIL), system-on-chip, system-on-package techniques for integration of electronics and photonics, 3D printing, powerful embedded computing platforms, networked solutions as well as advances in chemometrics modeling. This paper will summarize recent work on spectrometer and sensor miniaturization at VTT Technical Research Centre of Finland. Fabry-Perot interferometer (FPI) tunable filter technology has been developed in two technical versions: Piezoactuated FPIs have been applied in miniature hyperspectral imaging needs in light weight UAV and nanosatellite applications, chemical imaging as well as medical applications. Microfabricated MOEMS FPIs have been developed as cost-effective sensor platforms for visible, NIR and IR applications. Further examples of sensor miniaturization will be discussed, including system-on-package sensor head for mid-IR gas analyzer, roll-to-roll printed Surface Enhanced Raman Scattering (SERS) technology as well as UV imprinted waveguide sensor for formaldehyde detection.

This study investigated the impact of trauma exposure characteristics on post-traumatic stress disorder (PTSD) and psychiatric co-morbidity among Syrian refugees. One thousand one hundred and ninety-seven refugees residing in Turkey and Sweden participated in the research. They completed the Harvard Trauma Questionnaire and the General Health Questionnaire-28. Forty-three percent of refugees met the cutoff for PTSD. After adjusting for location of residence, witnessing horror and exposure to life threat and assault were significantly correlated with PTSD and psychiatric co-morbidity respectively. Death of, or life threat to family members or friends were significantly correlated with both distress outcomes. Refugees residing in Turkey had significantly higher levels of PTSD, psychiatric co-morbidity and trauma characteristics than those living in Sweden. To conclude, Syrian refugees who witnessed horror, life threat or had family or friends die, tended to have elevated psychological distress. Levels of distress among resettled refugees can vary depending on country of resettlement. We recommend systematic mental health screening and implementation of psychotherapeutic interventions to address issues pertaining to subjective experience of resettlement and trauma exposure for Syrian refugees.

Prior to the conflict, Syria had relatively high fertility rates. In 2010, it had the sixth highest total fertility rate in the Arab World, but it witnessed a fertility decline before the conflict in 2011. Displacement during conflict influences fertility behaviour, and meeting the contraceptive needs of displaced populations is complex. This study explored the perspectives of women and service providers about fertility behaviour of and service provision to Syrian refugee women in Bekaa, Lebanon. We used qualitative methodology to conduct 12 focus group discussions with Syrian refugee women grouped in different age categories and 13 in-depth interviews with care providers from the same region. Our findings indicate that the displacement of Syrians to Lebanon had implications on the fertility behaviour of the participants. Women brought their beliefs about preferred family size and norms about decision-making into an environment where they were exposed to both aid and hardship. The unaffordability of contraceptives in the Lebanese privatised health system compared to their free provision in Syria limited access to family planning services. Efforts are needed to maintain health resources and monitor health needs of the refugee population in order to improve access and use of services.

Introduction Studying mental and physical health problems in refugees facilitates providing suitable health care, thus improving their quality of life. We studied depression tendency in Syrian refugees in Jordan in the light of chronic diseases and medication availability. Also, depression prevalence and depression comorbidity with chronic diseases were identified. Methods In this multicenter cross-sectional survey, data from Syrian refugees attending Caritas centers in 6 Jordanian cities from November 2013 through June 2014 were analyzed. Participants’ demographics, depression, previously diagnosed chronic diseases, and newly diagnosed chronic diseases and the availability of medications were studied. Logistic regression was used to examine predictors for depression. Results Of 765 refugees who participated, about one-third demonstrated significant depression as measured by the Beck Depression Inventory. Descriptive analyses showed that depression was comorbid in 35% of participants with previously diagnosed chronic diseases and in 40% of participants with newly diagnosed chronic diseases. Newly diagnosed chronic diseases and lack of medications significantly contributed to depression, but the regression model as a whole explained less than 5% of the variance. Conclusion Because the regression model showed low effect size, we concluded that newly diagnosed chronic diseases and medication shortages could not predict depression in Syrian refugees residing in Jordan. Therefore, further studies of additional factors are recommended. Prompt measures have to be taken to prevent the spread of chronic diseases and improve mental health in this fragile population.

The Syrian civil war since 2011 has led to one of the most complex humanitarian emergencies in history. The objective of this study was to document the impact of the conflict on the familial, educational, and public health state of Syrian children. A cross-sectional observational study was conducted in May 2015. Health care workers visited families with a prospectively designed data sheet in 4 Northern Syrian governorates. The 1001 children included in this study originated from Aleppo (41%), Idleb (36%), Hamah (15%), and Lattakia (8%). The children's median age was 6 years (range, 0-15 years; interquartile range, 3-11 years), and 61% were boys. Almost 20% of the children were internally displaced, and 5% had deceased or missing parents. Children lacked access to safe drinking water (15%), appropriate sanitation (23%), healthy nutrition (16%), and pediatric health care providers (64%). Vaccination was inadequate in 72%. More than half of school-aged children had no access to education. Children in Idleb and Lattakia were at greater risk of having unmet public health needs. Younger children were at greater risk of having an incomplete vaccination state. After 4 years of civil war in Syria, children have lost parents, live in substandard life quality circumstances, and are at risk for outbreaks because of worsening vaccination states and insufficient availability of health care providers.

Calculation of neutron importance function in fissionable assemblies using Monte Carlo method

International Nuclear Information System (INIS)

Feghhi, S.A.H.; Shahriari, M.; Afarideh, H.

2007-01-01

The purpose of the present work is to develop an efficient solution method for the calculation of neutron importance function in fissionable assemblies for all criticality conditions, based on Monte Carlo calculations. The neutron importance function has an important role in perturbation theory and reactor dynamic calculations. Usually this function can be determined by calculating the adjoint flux while solving the adjoint weighted transport equation based on deterministic methods. However, in complex geometries these calculations are very complicated. In this article, considering the capabilities of MCNP code in solving problems with complex geometries and its closeness to physical concepts, a comprehensive method based on the physical concept of neutron importance has been introduced for calculating the neutron importance function in sub-critical, critical and super-critical conditions. For this propose a computer program has been developed. The results of the method have been benchmarked with ANISN code calculations in 1 and 2 group modes for simple geometries. The correctness of these results has been confirmed for all three criticality conditions. Finally, the efficiency of the method for complex geometries has been shown by the calculation of neutron importance in Miniature Neutron Source Reactor (MNSR) research reactor

ABSTRACT In the sixth year of the Syrian conflict, 11 million people have been displaced, including more than 1.1 million seeking refuge in Lebanon. Prior to the crisis, noncommunicable diseases (NCDs) accounted for 80% of all deaths in Syria, and the underlying health behaviors such as tobacco use, obesity, and physical inactivity are still prevalent among Syrian refugees in Lebanon. Humanitarian agencies initially responded to the acute health care needs of refugees by delivering services to informal settlements via mobile medical clinics. As the crisis has become more protracted, humanitarian response plans have shifted their focus to strengthening local health systems in order to better address the needs of both the host and refugee populations. To that end, we identified gaps in care for NCDs and launched a program to deliver chronic disease care for refugees. Based on a participatory needs assessment and community surveys, and building on the success of community health programs in other contexts, we developed a network of 500 refugee outreach volunteers who are supported with training, supervision, and materials to facilitate health promotion and disease control for community members, target NCDs and other priority conditions, and make referrals to a primary health care center for subsidized care. This model demonstrates that volunteer refugee health workers can implement community-based primary health activities in a complex humanitarian emergency. PMID:28928227

Conclusion: among injuries related to war, the highest rate of mortality was observed in head–neck, abdomen and vascular injuries. We believe that the higher mortality rate in the Syrian Civil War, compared to the Bosnia, Vietnam, Lebanon and Afghanistan wars, is due to seeing civilians as a direct target during war.

The aim of the research was to induce mutations characterized by lodging resistant and high yielding ability in two syrian local durum wheat land races. This research was carried out at two periods during 1983-1987 and from 1991-1993. At the first period, Kernels of Hourani and Senatore Cappelle were treated with 10, 15, 20, 25 and 30 K rad of gamma rays at the Laboratory of the commission of Syrian Atomic Energy to induce mutations. The treated Kernels were planted in 1983/1984 season. After that, selection were practicised on plants which characterized by good performance and lodging resistant. During the successive seasons, screening were made on mutant lines to keep out only lines which show adaptability to intensive cultivation. Second period includes testing of selected lines at two govern orates of syria (Raqqa and Aleppo) during three successive seasons; 1991/1992 and 1992/1993 under intensive cultivation conditions (fertilization, irrigation, stands, etc.).

Retention and mobilization by Ca-DTPA of 241 Am and 252 Cf from rats, Syrian and Chinese hamsters are compared. Previous observations of a much longer residence time of actinides in hamsters liver than in rat liver are confirmed. Identical dose-effect functions were obtained for skeleton of rats and Syrian hamsters whereas 252 Cf removal from Chinese hamster skeleton was lower. The mobilization of 241 Am was lower than that of 252 Cf. With regard to species differences, qualitatively similar results were obtained for 241 Am as for 252 Cf. The results will be discussed with regard to the reduction by DTPA treatment of radiation risk in animal species with different biological half times of actinides in their livers. In this connection, attention will be paid to the usefulness of long-term DTPA treatment

Anastomosis is a common surgical procedure using staples or sutures in an open or laparoscopic surgery. A more effective and much less invasive alternative is to apply the mechanical pressure on the tissue over a few days [1]. Since the pressure is produced by the attractive force between two permanent magnets, the procedure is called magnamosis[1]. To ensure the two magnets are perfectly aligned during the surgery, a miniaturized batteryless Radio Frequency IDentification (RFID) tag is developed to wirelessly telemeter the status of a pressure sensitive mechanical switch. Using the multi-layer circular spiral coil design, the diameter of the RFID tag is shrunk to 10, 15, 19 and 27 mm to support the magnamosis for children as well as adults. With the impedance matching network, the operating distance of these four RFID tags are longer than 10 cm in a 20 × 22 cm(2) area, even when the tag's normal direction is 45° off the antenna's normal direction. Measurement results also indicate that there is no noticeable degradation on the operating distance when the tag is immersed in saline or placed next to the rare-earth magnet. The miniaturized RFID tag presented in this paper is able to support the magnamosis and other medical applications that require the miniaturized RFID tag.

Lung lecithin synthesis in Syrian hamster lung: effect of pulmonary lavage

International Nuclear Information System (INIS)

Henderson, R.F.

1976-01-01

A single pulmonary lavage in the Syrian hamster stimulated the synthesis of both the surface-active dipalmitoyl lecithin and its proposed precursor, the unsaturated lecithins. The rate of breakdown of the two types of lung lecithin did not appear to be greatly affected by the lavage. The data were consistent with the view that alveolar lecithins are secreted by the tissue into the alveoli and that unsaturated lecithins are the precursors of dipalmitoyl lecithin

1994-01-01

For measurements of thermal diffusivity of miniature-size specimens heavily irradiated by neutrons, a new Q-switched laser-flash instrument was developed. In the present instrument the time-resolution was improved to 0.1 ms by using a laser-pulse width of 25 ns. The realization of high time-resolution made it possible to measure the thermal diffusivity of thin specimens. It is expected that copper of 0.7 mm thick, and SUS 304 of 0.1 mm could be used for the measurements. In case of ATJ graphite, 0.5 mm thick specimen could be used for the reliable measurement in the temperature range of 300-1300 K. (author)

2004-04-01

Full Text Available The purpose of this paper is to examine how ICT development is progressing and what kind of political and social effects have been occurring (or could occur in the near future in Middle Eastern Arabic countries. To examine this theme, this paper will adopt the Syrian Arab Republic as a case. To understand the Syrian government's policy toward the ICT development, it is necessary to examine the domestic political situation, since they are closely related. Under the Bashar Al- Asad's regime, we can confirm several reasons why they have to move forward on their ICT development policy and why it has become a crucial issue, which they cannot evade, as they had done under the previous regime, Hafez Al- Asad's regime. The situation that the Syrian government is facing right now is known by the term, "Dictator's Dilemma". This paper tries to provide bases in order to examine and explore this dilemma in Syria. Also, when we examine ICT development in Syria, it is important to consider the ICT support policies, which are mainly conducted by OECD countries and international organizations and stem from the issue of "Digital Divide". This is why international assistances could have great effect on ICT development in Syria. As a provisional conclusion of this paper, I will summarize how we can understand the current situation of ICT development in Syria, and I will also comment on the future prospect of the dilemma that the Syrian government is facing at the present time.

Evaluation of an accelerated lambing system in Syrian Awassi ewes, using hormonal treatments inside and outside the breeding season

International Nuclear Information System (INIS)

Zarkawi, M.

2010-04-01

An experiment was carried out on Syrian Awassi ewes to assess the accelerated lambing system (three lambings in 2 years) by synchronising and induction of oestrus and increasing ovulation rate using hormonal treatments (intravaginal sponges: FGA + equine chorionic gonadotrophin: eCG). Fifty intact cyclic Syrian Awassi ewes aged 2- 4 years with an average live weight of 51.4 kg were used for 4 years (6 lambings). Ewes were divided into 2 groups: 40 ewes in the treated (T) and 10 in the control (C). Ewes in the T group were treated with FGA for 14 days and injected intramuscularly at sponge withdrawal with 500 IU eCG. Results indicated that, throughout the 6 breeding periods, oestrus induction rate was 100%, and all ewes in the T group were mated within 1-5 days post sponge removal as compared to 10-11 days for ewes in the C group. Treated ewes had higher rates of lambing, multiple birth and fecundity. Repeated administration of eCG (6 times at 8 months interval) had no negative effect on fertility of Syrian Awassi ewes. However, anti-eCG antibodies were produced following eCG injections. (author)

Rihawy, M.S.; Bakraji, E.H.; Odeh, A.

2014-01-01

The chemical composition and concentration of Syrian cumin (Cuminum cyminum L.) were investigated. The particle-induced X-ray emission (PIXE) analytical technique was used to analyze a wide range of elements from Mg to Sr. The advantages and disadvantages of the PIXE technique in plant material elemental analysis are discussed. A high level of iron was detected in the cumin samples, clarifying the possible contribution of cumin to maintaining the immune system. The contribution of the elements in cumin seeds to the dietary recommended intakes (DRI) of elements was evaluated. Additionally, GC–MS measurements were performed to determine the chemical composition of cumin essential oil. Twenty-one components were identified, and cuminaldehyde, γ-terpinene, o-cymene, limonene and β-pinene were determined to be the major constituents. A correlation between the chemical composition of cumin seeds and their use as a traditional remedy is proposed. - Highlights: • To our knowledge, there is no published studies focus on the Syrian cumin composition (neither elemental nor essential oil components) in spite of its valuable medicinal importance in the country. • This work is basically dedicated to investigate both elemental content and essential oil component of the Syrian cumin seeds. • The elemental analysis was performed using PIXE, a very powerful elemental analysis technique and the essential oil components were determined using GC–MS

In this study, we examine the role of nuclear data in Instrumental Neutron Activation Analysis (INAA) particularly as it affects determination of reactor flux parameters and application of comparator methods. The work reviewed the available sources of nuclear data, the variations that exist from one source to the other and the effects of such variations on INAA. Measurement of Neutron flux parameters in inner and outer irradiation channel of a miniature neutron source reactor was carried out using two independent nuclear data sources to investigate the effects of inconsistency of nuclear data on the precision of analytical result. The result obtained shows a slight variation of flux parameters with nuclear data source. It was also observed that modification of the earlier compiled basic nuclear data lead to inconsistencies in the secondary data that applies it. (author)

Miniature mass analyzer

CERN Document Server

Cuna, C; Lupsa, N; Cuna, S; Tuzson, B

2003-01-01

The paper presents the concept of different mass analyzers that were specifically designed as small dimension instruments able to detect with great sensitivity and accuracy the main environmental pollutants. The mass spectrometers are very suited instrument for chemical and isotopic analysis, needed in environmental surveillance. Usually, this is done by sampling the soil, air or water followed by laboratory analysis. To avoid drawbacks caused by sample alteration during the sampling process and transport, the 'in situ' analysis is preferred. Theoretically, any type of mass analyzer can be miniaturized, but some are more appropriate than others. Quadrupole mass filter and trap, magnetic sector, time-of-flight and ion cyclotron mass analyzers can be successfully shrunk, for each of them some performances being sacrificed but we must know which parameters are necessary to be kept unchanged. To satisfy the miniaturization criteria of the analyzer, it is necessary to use asymmetrical geometries, with ion beam obl...

Novel lipoprotein density profiling in healthy dogs of various breeds, healthy miniature schnauzers, and miniature schnauzers with hyperlipidemia

Science.gov (United States)

2013-01-01

Background Despite the importance of abnormalities in lipoprotein metabolism in clinical canine medicine, the fact that most previously used methods for lipoprotein profiling are rather laborious and time-consuming has been a major obstacle to the wide clinical application and use of lipoprotein profiling in this species. The aim of the present study was to assess the feasibility of a continuous lipoprotein density profile (CLPDP) generated within a bismuth sodium ethylenediaminetetraacetic acid (NaBiEDTA) density gradient to characterize and compare the lipoprotein profiles of healthy dogs of various breeds, healthy Miniature Schnauzers, and Miniature Schnauzers with primary hypertriacylglycerolemia. A total of 35 healthy dogs of various breeds with serum triacylglycerol (TAG) and cholesterol concentrations within their respective reference intervals were selected for use as a reference population. Thirty-one Miniature Schnauzers with serum TAG and cholesterol concentrations within their respective reference intervals and 31 Miniature Schnauzers with hypertriacylglyceridemia were also included in the study. Results The results suggest that CLPDP using NaBiEDTA provides unique diagnostic information in addition to measurements of serum TAG and cholesterol concentrations and that it is a useful screening method for dogs with suspected lipoprotein metabolism disorders. Using the detailed and continuous density distribution information provided by the CLPDP, important differences in lipoprotein profiles can be detected even among dogs that have serum TAG and cholesterol concentrations within the reference interval. Miniature Schnauzers with serum TAG and cholesterol concentrations within the reference interval had significantly different lipoprotein profiles than dogs of various other breeds. In addition, it was further established that specific lipoprotein fractions are associated with hypertriacylglyceridemia in Miniature Schnauzers. Conclusions The results of the

Miniature Scroll Pumps Fabricated by LIGA

Science.gov (United States)

Wiberg, Dean; Shcheglov, Kirill; White, Victor; Bae, Sam

2009-01-01

Miniature scroll pumps have been proposed as roughing pumps (low - vacuum pumps) for miniature scientific instruments (e.g., portable mass spectrometers and gas analyzers) that depend on vacuum. The larger scroll pumps used as roughing pumps in some older vacuum systems are fabricated by conventional machining. Typically, such an older scroll pump includes (1) an electric motor with an eccentric shaft to generate orbital motion of a scroll and (2) conventional bearings to restrict the orbital motion to a circle. The proposed miniature scroll pumps would differ from the prior, larger ones in both design and fabrication. A miniature scroll pump would include two scrolls: one mounted on a stationary baseplate and one on a flexure stage (see figure). An electromagnetic actuator in the form of two pairs of voice coils in a push-pull configuration would make the flexure stage move in the desired circular orbit. The capacitance between the scrolls would be monitored to provide position (gap) feedback to a control system that would adjust the drive signals applied to the voice coils to maintain the circular orbit as needed for precise sealing of the scrolls. To minimize power consumption and maximize precision of control, the flexure stage would be driven at the frequency of its mechanical resonance. The miniaturization of these pumps would entail both operational and manufacturing tolerances of pump components. In addition, the vibrations of conventional motors and ball bearings exceed these tight tolerances by an order of magnitude. Therefore, the proposed pumps would be fabricated by the microfabrication method known by the German acronym LIGA ( lithographie, galvanoformung, abformung, which means lithography, electroforming, molding) because LIGA has been shown to be capable of providing the required tolerances at large aspect ratios.

2018-01-01

In order to improve measurement techniques for neutron flux assessment, a unique system for online measurement of fast neutron flux has been developed and recently qualified in-pile by the French Alternative Energies and Atomic Energy Commission (CEA) in cooperation with the Belgian Nuclear Research Centre (SCK•ECEN). The Fast-Neutron-Detection-System (FNDS) has been designed to monitor accurately high-energy neutrons flux (E > 1 MeV) in typical Material Testing Reactor conditions, where overall neutron flux level can be as high as 1015 n.cm-2.s-1 and is generally dominated by thermal neutrons. Moreover, the neutron flux is coupled with a high gamma flux of typically a few 1015 γ.cm-2.s-1, which can be highly disturbing for the online measurement of neutron fluxes. The patented FNDS system is based on two detectors, including a miniature fission chamber with a special fissile material presenting an energy threshold near 1 MeV, which can be 242Pu for MTR conditions. Fission chambers are operated in Campbelling mode for an efficient gamma rejection. FNDS also includes a specific software that processes measurements to compensate online the fissile material depletion and to adjust the sensitivity of the detectors, in order to produce a precise evaluation of both thermal and fast neutron flux even after long term irradiation. FNDS has been validated through a two-step experimental program. A first set of tests was performed at BR2 reactor operated by SCK•CEN in Belgium. Then a second test was recently completed at ISIS reactor operated by CEA in France. FNDS proved its ability to measure online the fast neutron flux with an overall accuracy better than 5%.

Feasibility studies on large sample neutron activation analysis using a low power research reactor

International Nuclear Information System (INIS)

Gyampo, O.

2008-06-01

Instrumental neutron activation analysis (INAA) using Ghana Research Reactor-1 (GHARR-1) can be directly applied to samples with masses in grams. Samples weights were in the range of 0.5g to 5g. Therefore, the representativity of the sample is improved as well as sensitivity. Irradiation of samples was done using a low power research reactor. The correction for the neutron self-shielding within the sample is determined from measurement of the neutron flux depression just outside the sample. Correction for gamma ray self-attenuation in the sample was performed via linear attenuation coefficients derived from transmission measurements. Quantitative and qualitative analysis of data were done using gamma ray spectrometry (HPGe detector). The results of this study on the possibilities of large sample NAA using a miniature neutron source reactor (MNSR) show clearly that the Ghana Research Reactor-1 (GHARR-1) at the National Nuclear Research Institute (NNRI) can be used for sample analyses up to 5 grams (5g) using the pneumatic transfer systems.

FY 2006 Miniature Spherical Retroreflectors Final Report

Anheier, Norman C.; Bernacki, Bruce E.; Krishnaswami, Kannan

2006-12-28

Research done by the Infrared Photonics team at Pacific Northwest National Laboratory (PNNL) is focused on developing miniature spherical retroreflectors using the unique optical and material properties of chalcogenide glass to reduce both performance limiting spherical aberrations. The optimized optical performance will provide efficient signal retroreflection that enables a broad range of remote detection scenarios for mid-wave infrared (MWIR) and long-wave infrared (LWIR) sensing applications. Miniature spherical retroreflectors can be developed to aid in the detection of signatures of nuclear proliferation or other chemical vapor or radiation signatures. Miniature spherical retroreflectors are not only well suited to traditional LIDAR methods for chemical plume detection and identification, but could enable remote detection of difficult semi-volatile chemical materials or low level radiation sources.

Given the scarcity of mental health resources available for refugees in areas of conflict, it is imperative to investigate interventions that would be accepted by the refugees. In this study we surveyed 354 Syrian refugees using the HADStress screening tool and asked about their openness to referral to psychiatry and telepsychiatry. Of the surveyed sample, 41.8% had scores on HADStress that correlate to posttraumatic stress disorder. However, only 34% of the whole sample reported a perceived need to see a psychiatrist, and of those only 45% were open to telepsychiatry. Women, those who were bilingual, and those with positive HADStress status were less likely to accept telepsychiatry; however, this finding did not reach statistical significance. This study reports a partial acceptance of Syrian refugees for telepsychiatric services despite the high prevalence of psychological stress.

Rhetoric of civil conflict management: United Nations Security Council debates over the Syrian civil war

Directory of Open Access Journals (Sweden)

Juraj Medzihorsky

2017-04-01

Full Text Available This paper introduces a spatial model of civil conflict management rhetoric to explore how the emerging norm of responsibility to protect shapes major power rhetorical responses to civil war. Using framing theory, we argue that responsibility to protect functions like a prescriptive norm, such that representing a conflict as one of (1 human rights violations (problem definition, implies rhetorical support for (2 coercive outside intervention (solution identification. These dimensions reflect the problem-solution form of a prescriptive norm. Using dictionary scaling with a dynamic model, we analyze the positions of UN Security Council members in debates over the Syrian Civil War separately for each dimension. We find that the permanent members who emphasized human rights violations also used intervention rhetoric (UK, France, and the US, and those who did not used non-intervention rhetoric (Russia and China. We conclude that, while not a fully consolidated norm, responsibility to protect appears to have structured major power rhetorical responses to the Syrian Civil War.

2012-01-01

14 known point mutations in the androgen receptor gene (AR) causing male infertility were screened by real time PCR and by DNA sequencing, in order to identify point mutations in the AR gene causing infertility in azoospermic men. We screened 110 Syrian patients suffering from non-obstructive azoospermia with no chromosomal aberrations or AZF micro deletions. We discovered a new AR mutation, del 57Leu, described for the first time as a possible cause of male infertility. Furthermore, we found two patients with the Ala474Val mutation and one patient bearing the Pro390Ser mutation. Our results indicate that these mutations are significant markers for idiopathic male infertility in the Syrian society and in Mediterranean populations in general. (author)

Research on deep hibernators almost exclusively uses species captured from the wild or from local breeding. An exception is Syrian hamster (Mesocricetus auratus), the only standard laboratory animal showing deep hibernation. In deep hibernators, several factors influence hibernation quality, including body mass, sex and diet. We examined hibernation quality in commercially obtained Syrian hamsters in relation to body mass, sex and a diet enriched in polyunsaturated fatty acids. Animals (M/F:30/30, 12 weeks of age) were obtained from Harlan (IN, USA) and individually housed at 21 °C and L:D 14:10 until 20 weeks of age, followed by L:D 8:16 until 27 weeks. Then conditions were changed to 5 °C and L:D 0:24 for 9 weeks to induce hibernation. Movement was continuously monitored with passive infrared detectors. Hamsters were randomized to control diet or a diet 3× enriched in linoleic acid from 16 weeks of age. Hamsters showed a high rate of premature death (n = 24, 40%), both in animals that did and did not initiate torpor, which was unrelated to body weight, sex and diet. Time to death (31.7 ± 3.1 days, n = 12) or time to first torpor bout (36.6 ± 1.6 days, n = 12) was similar in prematurely deceased hamsters. Timing of induction of hibernation and duration of torpor and arousal was unaffected by body weight, sex or diet. Thus, commercially obtained Syrian hamsters subjected to winter conditions showed poor survival, irrespective of body weight, sex and diet. These factors also did not affect hibernation parameters. Possibly, long-term commercial breeding from a confined genetic background has selected against the hibernation trait.

Full Text Available Background. Hearing impairments (HI are the most common birth defect worldwide. Very large numbers of genes have been identified but the most profound is GJB2. The clinical interest regarding this gene is very pronounced due to its high carrier frequency (0.5–5.4% across different ethnic groups. This study aimed to determine the prevalence of common GJB2 mutations in Syrian patients with profound sensorineural HI. Methods. We carried out PCR, restriction enzyme based screening, and sequencing of 132 Syrian patients diagnosed clinically with hereditary deafness for different GJB2 mutations. Results. The result revealed that, in GJB2 gene, c.35delG is the most prevalent among affected studied subjects (13.64%, followed by c.457G>A (2.4%. Conclusion. The benefit of this study on the one hand is its first report of prelingual deafness causative gene mutations identified by sequencing technology in the Syrian families. It is obvious from the results that the deployment in biomedical research is highly effective and has a great impact on the ability to uncover the cause of genetic variation in different genetic diseases.

Political violence is known to cause psychological distress. There is a large body of empirical studies drawing correlations between war trauma, torture, and post-traumatic stress disorder (PTSD). However, there are few studies on the effects of war-related trauma among Syrian refugees after events following the 'Arab Spring' uprisings between 2010 and 2012. This study examines the association of PTSD symptoms with torture and other traumatic events among Syrian Kurdish refugees living in Kurdistan Region, Iraq. The experiences and PTSD symptoms among 91 Syrian Kurdish refugees in the Arbat camp in the Sulaymaniyah Governorate of the Kurdistan Region of Iraq were assessed using the Harvard Trauma Questionnaire, sections I, IV, and V. Results showed that the estimated levels of PTSD symptoms were high: between 35 and 38%. There were no significant gender differences in the occurrence of PTSD symptoms. However, men reported more general traumatic experiences than women. There were significant positive correlations between PTSD symptoms with traumatic events and torture ( r = 0.500, r = 0.366, respectively). Examining the mental health impact of torture and other traumatic events among refugees has possible implications for organizations managing rehabilitation programs for individuals who have been exposed to traumatic events.

The civil war in Syria including the deliberate targeting of healthcare services resulted in a complex humanitarian emergency, seriously affecting children's health. The objectives of this study are to document diagnoses and disease categories in Northern Syrian children after four years of conflict, and to document infectious diseases and injuries in this vulnerable population. In a prospective cross-sectional observational sample study conducted in May 2015, healthcare workers registered demographics, comorbidities, and diagnoses (categorised according to the International Classification of Diseases version 10) in children visited at home and in internally displaced persons camps in four Syrian governorates. Of 1080 filled-out records, 1002 were included. Children originated from Aleppo (41%), Idleb (36%), Hamah (15%) and Lattakia (8%). Median age was 6 years (0-15; IQR 3-11), 61% were boys, 40% were younger than 5 years old. Children suffered from respiratory (29%), neurological (19%), digestive (17%), eye (5%) and skin (5%) diseases. Clinical malnutrition was seen in 4%, accidental injury in 3%, intentional injury in 1%, and mental disorders in 2%. Overall, 64% had features of infectious diseases (OR 0.635; CI 0.605-0.665). Most common comorbidities were chronic respiratory diseases (14, malnutrition (5%), acute flaccid paralysis (5%), and epilepsy (4%). Logistic regression analysis indicated that the risk for children to have communicable diseases was higher in Aleppo than in Idleb (OR 1.7; CI 1.2-2.3), Hamah (OR 4.9; CI 3.3-7.5), or Lattakia (OR 5.5; CI 3.3-9.3). Children in Aleppo and Lattakia were more at risk to be injured than in Idleb (OR 5.6; CI 2.1-14.3), or in Hamah (OR 5.9; CI 1.4-25.6), but more often from intentional violence in Lattakia. Mental problems were more prominent in Hamah. Four years far in the conflict, 64% of the studied children in four Northern Syrian governorates suffer from infections, mostly from respiratory, neurological and

Miniature synaptic currents have long been known to represent random transmitter release under resting conditions, but much remains to be learned about their nature and function in central synapses. In this work, we describe a new class of miniature currents ("preminis") that arise by the autocrine activation of axonal receptors following random vesicular release. Preminis are prominent in gabaergic synapses made by cerebellar interneurons during the development of the molecular layer. Unlike ordinary miniature postsynaptic currents in the same cells, premini frequencies are strongly enhanced by subthreshold depolarization, suggesting that the membrane depolarization they produce belongs to a feedback loop regulating neurotransmitter release. Thus, preminis could guide the formation of the interneuron network by enhancing neurotransmitter release at recently formed synaptic contacts. Copyright 2010 Elsevier Inc. All rights reserved.

Miniaturized Environmental Monitoring Instrumentation

Energy Technology Data Exchange (ETDEWEB)

C. B. Freidhoff

1997-09-01

The objective of the Mass Spectrograph on a Chip (MSOC) program is the development of a miniature, multi-species gas sensor fabricated using silicon micromachining technology which will be orders of magnitude smaller and lower power consumption than a conventional mass spectrometer. The sensing and discrimination of this gas sensor are based on an ionic mass spectrograph, using magnetic and/or electrostatic fields. The fields cause a spatial separation of the ions according to their respective mass-to-charge ratio. The fabrication of this device involves the combination of microelectronics with micromechanically built sensors and, ultimately, vacuum pumps. The prototype of a chemical sensor would revolutionize the method of performing environmental monitoring for both commercial and government applications. The portable unit decided upon was the miniaturized gas chromatograph with a mass spectrometer detector, referred to as a GC/MS in the analytical marketplace.

Spectral effects in low-dose fission and fusion neutron irradiated metals and alloys

International Nuclear Information System (INIS)

Heinisch, H.L.; Atkin, S.D.; Martinez, C.

1986-04-01

Flat miniature tensile specimens were irradiated to neutron fluences up to 9 x 10 22 n/m 2 in the RTNS-II and in the Omega West Reactor. Specimen temperatures were the same in both environments, with runs being made at both 90 0 C and 290 0 C. The results of tensile tests on AISI 316 stainless steel, A302B pressure vessel steel and pure copper are reported here. The radiation-induced changes in yield strength as a function of neutron dose in each spectrum are compared. The data for 316 stainless steel correlate well on the basis of displacements per atom (dpa), while those for copper and A302B do not. In copper the ratio of fission dpa to 14 MeV neutron dpa for a given yield stress change is about three to one. In A302B pressure vessel steel this ratio is more than three at lower fluences, but the yield stress data for fission and 14 MeV neutron-irradiated A302B steel appears to coalesce or intersect at the higher fluences

2017-01-01

Full Text Available Rail-gun should not only be used to military applications, but also can be developed as applications in the civilian aspects of the market. With the development of the electromagnetic launch technology, based on the similarity theory, using the existing rail-gun model to guide the construction of more economical miniature calibre rail-guns, and apply it in some machinery and equipment, this idea will open up a wider rail-gun application space. This article will focus on the feasibility of application of miniature calibre rail-guns in the mechanical arm. This paper designs the schematic diagram, then theoretical analyzes force conditions of the armature in the mechanical arm, calculates the possible range of the current amplitude and so on. The existing rail-gun model can be used to guides design the circuit diagram of the miniature calibre rail-gun. Based on the similarity theory and many simulation experiments, designed the experimental parameters of a miniature rail-gun and analyzed the current, Lorentz force, velocity, and location of the existing rail-gun and miniature rail-gun. The results show that the rail-gun launching technology applied to robot arms is feasibility. The application of miniature calibre rail-guns in the mechanical arm will benefit to the further development of rail-guns.

2004-01-01

Polonium-210 was determined in 34 kinds of imported tea and 9 kinds of mat collected from the Syrian local market. The 210 Po concentration was found to vary from 5.5 to 39 Bq x kg -1 and 47 to 82 Bq x kg -1 in tea and mat samples, respectively. In addition 210 Po was also determined in tea and mat infusions where different infusion conditions have been examined: amount, temperature and infusion time. The results have shown that the amount of 210 Po transferred from tea and mat leaves to the aqueous extract ranged from 9 to 21% and 3 to 15%, respectively. The annual intake of 210 Po by Syrians due to tea consumption and mat infusions was calculated and found to be 9 Bq and 151 Bq for tea and mat respectively: washing of mat with warm water is recommended before preparation the infusions to decrease the annual intake of 210 Po.

Reporting from Turkey's frontier with the civil war in Syria, we examined the demographic characteristics, psychiatric diagnoses and treatments for the Syrian refugee patients who have presented to Gaziantep University, Child and Adolescent Psychiatry Clinic through 2016 and the first half of 2017 retrospectively, having aimed to understand the special characteristics and needs of this novel patient group. Within a year and a half, we evaluated 51 children and adolescents and 25 (51%) had come from refugee camps, where primary healthcare services are available. Twenty-eight patients (54.9%) had special educational needs. Among our patients, there were only 15 (29.4%) girls. After our experience with refugee patients, we conclude that the role of primary healthcare services in reaching psychiatric treatment should be investigated for child refugees that special educational needs of Syrian refugees in Turkey needs urgent attention and that more research is needed to establish whether gender may be a factor in negligence of internalising symptoms by refugee families.

Puspitasari, N. B.; Pujotomo, D.; Muhardiansyah, H.

2017-12-01

The number of electronic devices in Indonesia in the last 10 years has been increasing quite drastically which contributes to more electronic waste. E-waste or electronic waste have different characteristics from other kinds of waste. Components of electronic waste often poisonous, consisting dangerous chemicals. The telephone card wasted is also an electronic waste. One alternative to handle and manage telephone card waste is to recycle it into collectible miniature vehicles. But the price of these miniatures is quite high, causing low interest in buying them. A research on the price of miniature vehicles in relation to consumers’ Ability to Pay (ATP) and Willingness to Pay (WTP) needs to be done. Segmentation analysis data, target, product positioning and product marketing mix are needed before commencing the research. Data collection is done through a survey by spreading questionnaire to 100 miniature vehicle collectors in Semarang, questioning their ability and willingness to pay recycled miniature vehicles. Calculations showed average ATP of Rp.112.520, 24 and average WTP of Rp.76.870. The last result showed the estimate pricing according to ATP and WTP which is Rp.66.000 with 58% of the respondents claiming to be willing and able to pay that price.

Agency, resistance and (forced mobilities.The case of Syrian refugees in transit through Italy.

Directory of Open Access Journals (Sweden)

Chiara Denaro

Full Text Available Abstract During the biennium 2013–2014 Syrian refugees started to reach Italy through Mediterranean seaborne migration routes, from Libya and Egypt. Their presence contributed to partially modifying the configuration of the incoming migration flows to Italy, both in terms of socio-demographic composition and access to the European asylum system. Data shows that most of the Syrian refugees who landed in Italy between 2013 and 2014 decided to pursue their journeys to Northern Europe, by overcoming the restrictions imposed by the Dublin Regulation. The article focuses on the phenomenon of transit, as an interesting standpoint from which to observe certain acts of agency and resistance, put in place by refugees in order to “choose the country where to live” (Denaro, 2016: the refusal to provide fingerprints during identification, the organization of hunger strikes, the secondary mobility per se. Moreover, the article attempts to shed light on the relational and socio-political context in which these practices have taken shape, by focusing on the construction of relationships with activists and volunteers, and the (explicit and tacit processes of negotiation which refugees conducted with police authorities and other stakeholders.

Soft error modeling and analysis of the Neutron Intercepting Silicon Chip (NISC)

International Nuclear Information System (INIS)

Celik, Cihangir; Unlue, Kenan; Narayanan, Vijaykrishnan; Irwin, Mary J.

2011-01-01

Soft errors are transient errors caused due to excess charge carriers induced primarily by external radiations in the semiconductor devices. Soft error phenomena could be used to detect thermal neutrons with a neutron monitoring/detection system by enhancing soft error occurrences in the memory devices. This way, one can convert all semiconductor memory devices into neutron detection systems. Such a device is being developed at The Pennsylvania State University and named Neutron Intercepting Silicon Chip (NISC). The NISC is envisioning a miniature, power efficient, and active/passive operation neutron sensor/detector system. NISC aims to achieve this goal by introducing 10 B-enriched Borophosphosilicate Glass (BPSG) insulation layers in the semiconductor memories. In order to model and analyze the NISC, an analysis tool using Geant4 as the transport and tracking engine is developed for the simulation of the charged particle interactions in the semiconductor memory model, named NISC Soft Error Analysis Tool (NISCSAT). A simple model with 10 B-enriched layer on top of the lumped silicon region is developed in order to represent the semiconductor memory node. Soft error probability calculations were performed via the NISCSAT with both single node and array configurations to investigate device scaling by using different node dimensions in the model. Mono-energetic, mono-directional thermal and fast neutrons are used as the neutron sources. Soft error contribution due to the BPSG layer is also investigated with different 10 B contents and the results are presented in this paper.

A new/old type of neutron spectrometer

International Nuclear Information System (INIS)

Vylet, V.; Fasso, A.; Luckau, N.

1998-01-01

The proposed portable spectrometer is a large sphere made of a plastic scintillator loaded with boron, possibly enriched with boron 10. The sphere is divided into spherical shells coated with a reflective or opaque material. Each shell is made of two hemispherical shells or smaller segments. Each segment is connected by a light-guide to a photomultiplier or a photodiode. It might be possible to use miniature photomultipliers directly embedded in detector layers. Each shell measures the thermal fluence at a different moderator depth and the set of shell responses can be used to unfold the original neutron spectrum, covering the range of energies from thermal to 20 MeV.

Full Text Available Colonization of gut microbiota in mammals during the early life is vital to host health. The miniature piglet has recently been considered as an optimal infant model. However, less is known about the development of gut microbiota in miniature piglets. Here, this study was conducted to explore how the gut microbiota develops in weaned Congjiang miniature piglets. In contrast to the relatively stabilized gut fungal community, gut bacterial community showed a marked drop in alpha diversity, accompanied by significant alterations in taxonomic compositions. The relative abundances of 24 bacterial genera significantly declined, whereas the relative abundances of 7 bacterial genera (Fibrobacter, Collinsella, Roseburia, Prevotella, Dorea, Howardella, and Blautia significantly increased with the age of weaned piglets. Fungal taxonomic analysis showed that the relative abundances of 2 genera (Kazachstania and Aureobasidium significantly decreased, whereas the relative abundances of 4 genera (Aspergillus, Cladosporium, Simplicillium, and Candida significantly increased as the piglets aged. Kazachstania telluris was the signature species predominated in gut fungal communities of weaned miniature piglets. The functional maturation of the gut bacterial community was characterized by the significantly increased digestive system, glycan biosynthesis and metabolism, and vitamin B biosynthesis as the piglets aged. These findings suggest that marked gut microbial changes in Congjiang miniature piglets may contribute to understand the potential gut microbiota development of weaned infants.

Miniature, Single Channel, Memory-Based, High-G Acceleration Recorder (Millipen)

Rohwer, Tedd A.

1999-01-01

The Instrumentation and Telemetry Departments at Sandia National Laboratories have been instrumenting earth penetrators for over thirty years. Recorded acceleration data is used to quantify penetrator performance. Penetrator testing has become more difficult as desired impact velocities have increased. This results in the need for small-scale test vehicles and miniature instrumentation. A miniature recorder will allow penetrator diameters to significantly decrease, opening the window of testable parameters. Full-scale test vehicles will also benefit from miniature recorders by using a less intrusive system to instrument internal arming, fusing, and firing components. This single channel concept is the latest design in an ongoing effort to miniaturize the size and reduce the power requirement of acceleration instrumentation. A micro-controller/memory based system provides the data acquisition, signal conditioning, power regulation, and data storage. This architecture allows the recorder, including both sensor and electronics, to occupy a volume of less than 1.5 cubic inches, draw less than 200mW of power, and record 15kHz data up to 40,000 gs. This paper will describe the development and operation of this miniature acceleration recorder

Miniature fission chambers are suited tools for instrumenting experimental reactors, allowing online and in-core neutron measurements of quantities such as fission rates or reactor power. A new set of such detectors was produced by CEA to be used during the next experimental program at the EOLE facility starting in 2013. Some of these detectors will be employed in pulse mode for absolute measurements, thus requiring calibration. The calibration factor is expressed in mass units and thus called 'effective mass'. A calibration campaign was conducted in December 2012 at the SCK.CEN BR1 facility within the framework of the scientific cooperation VEP (VENUS-EOLE-PROTEUS) between SCK.CEN, CEA and PSI. Two actions were conducted in order to improve the calibration method. First a new characterisation of the thermal flux cavity and the MARK3 neutron flux conversion device performed by SCK.CEN allowed using calculated effective cross sections for determining detectors effective masses. Dosimetry irradiations were performed in situ in order to determine the neutron flux level and provide link to the metrological standard. Secondly two fission chambers were also calibrated at the CEA CALIBAN reactor (fast neutron spectrum), using the same method so that the results can be compared with the results obtained at the SCK.CEN. In this paper the calibration method and recent improvements on uncertainty reduction are presented. The results and uncertainties obtained in the two reactors CALIBAN and BR1 are compared and discussed. (authors)

Double and triple entanglement in a single neutron system

International Nuclear Information System (INIS)

Erdösi, D.

2015-01-01

Single-neutron interferometry is used in various experiments to study the foundations of quantum mechanics. The drawback of this technique, however, is that the contrast of neutron interferometers is very prone to disturbances, in particular, temperature variations. In order to achieve very low degrading of the contrast, we develop new devices to manipulate the neutron-s spin and energy in the interferometer. These devices open the door for quantum state generation with much higher fidelities than it has been possible so far in neutron interferometry. Spin rotators with time-dependent (radio-frequency (RF)) field change both spin and energy. We improve our RF spin-rotators for the interferometer by equipping them with miniature Helmholtz coils, which allows to adjust the energy shift due to each RF coil independently. This is essential for the generation of certain quantum states. This improvement is made possible by a new coil cooling method. Furthermore, we also develop new Larmor precession accelerators and decelerators that do not consume energy and hence do not produce heat at all. We demonstrate two applications of the new spin and energy manipulators by generating bi- and tripartite entanglement between the neutron's spin, energy and path degrees of freedom in the interferometer: we succeed in generating a Bell-like state and GHZ- and W-like states. For Bell state generation we also introduce a convenient spin preparation scheme that uses our Larmor precession manipulator. We achieve a considerably more significant violation of a Bell-like inequality than with the previous method, thus further confirming quantum contextuality. With our RF spin rotators we achieve for the GHZ- and W-like states fidelities between 95 and 99%. (author) [de

As Syria enters its fifth year of conflict, the number of civilians killed and injured continues to rise sharply. Along with this conflict comes the rapid decline of medical care, specifically cancer care. To determine physician and equipment availability, cancer screening and management, and possible solutions relative to various major cities, a survey was distributed to physicians inside Syria through the help of the humanitarian organization Syrian American Medical Society. Online surveys were distributed to both certified oncologists who work in cancer clinics and general physicians who work in rural and mobile clinics inside Syria. Variables assessed were physician specialty, location, population, cost, regional situation (besieged versus government controlled), and resource availability and access. Results were stratified by location and physician specialty. Survey results revealed a large shortage of specialized physicians and inhibited accessibility to screening and management options in besieged areas compared with government-controlled regions. Physicians within both government-controlled and besieged cities reported limited or no targeted agents, radiation therapy, clinical trials, bone marrow transplantation, positron emission tomography scans, magnetic resonance imaging, and genetic testing. The Syrian civil war has resulted in suboptimal oncology care in the majority of the region. In consideration of specific deficiencies in cancer care, we recommend several solutions that may better the level of care in Syria: patient education on medical documentation and self-examination; online consultation; and cheap, effective screening methods. The implementation of these recommendations may change the course of cancer care in a country that has deteriorated into the worst humanitarian crisis of the century.

Full Text Available With the value given to the art and the artist, high quality works of art in many fields were produced in the Ottoman Era. The art of weaving also lived its brightest period in terms of color, design, and weaving techniques in the Ottoman Empire in XVI. Ce ntury. The weaving products shaped the lifestyles of the people in those times and received great interest in the Palace as well. Silk woven fabrics had become such a great power in those times that it became the greatest symbol showing the power of the Ot toman Empire to the foreigners, and the determiner of the social standing within the society. The Ottoman Sultans used their clothing, which they made to become flamboyant with embroideries, to distinguish themselves from the public, and make them accept t heir power. Among the presents that were presented to the Sultans, clothes, kaftans, and similar fabrics as well as other precious presents, were frequent. The miniature manuscripts that were produced in the Palace are in the quality of unique documents t hat transfer yesterday’s knowledge to the modern age. It is easy to decode the dimensions of the clothing habits, decoration elements and hierarchy concepts of the Ottoman Era, as well as the weaving activities by using the miniature manuscripts. On the ot her hand, these elements constitute a rich alphabet in transferring the emotional structure of the society in those times, the traditions and habits to our world today. The greatest share in this effort belongs to the artists who depicted the miniatures by staying loyal to the texts in the manuscripts as well as to their active participation in the events of those times and their narrating the events as the very first observers. In addition, the muralists depicting the manuscripts and their undertaking the job of drawing the designs on the original fabric helped them to reflect the richness in the design of those times to the miniatures. In this study, the weavings and the accessories

Full Text Available This paper aims at explaining the lessons learned from the chemical attacks that took place in 2013 in the Syrian military conflict, especially the sarin attacks on the Ghouta area of Damascus on August 21. Despite the limitations the UN Mission found while investigating the use of chemical weapons (CW in Syria, some interesting conclusions for the scientific and medical community can be obtained from its reports. These include the advantages of the Chemical Weapons Convention procedure for the investigation of alleged CW use, when compared with the United Nations mechanism for similar investigations, the difficulties of differential diagnosis based only on clinical signs and symptoms and the impact of secondary contamination when responding to a CW attack.

The Syrian golden hamster drinks alcohol readily, but only achieves moderate blood alcohol levels, and does not go through withdrawal from alcohol. Because the hamster is a model of caloric homeostasis, both caloric content and reward value may contribute to the hamster’s alcohol consumption. The current study examines alcohol consumption in the hamster when a caloric or non-caloric sweet solution is concurrently available and caloric intake in the hamster before, during, and after exposure t...

Variable recruitment in bundles of miniature pneumatic artificial muscles.

DeLaHunt, Sylvie A; Pillsbury, Thomas E; Wereley, Norman M

2016-09-13

The natural compliance and force generation properties of pneumatic artificial muscles (PAMs) allow them to operate like human muscles in anthropomorphic robotic manipulators. Traditionally, manipulators use a single PAM or multiple PAMs actuated in unison in place of a human muscle. However, these standard manipulators can experience significant efficiency losses when operated outside their target performance ranges at low actuation pressures. This study considers the application of a variable recruitment control strategy to a parallel bundle of miniature PAMs as an attempt to mimic the selective recruitment of motor units in a human muscle. Bundles of miniature PAMs are experimentally characterized, their actuation behavior is modeled, and the efficiency gains and losses associated with the application of a variable recruitment control strategy are assessed. This bio-inspired control strategy allows muscle bundles to operate the fewest miniature PAMs necessary to achieve a desired performance objective, improving the muscle bundle's operating efficiency over larger ranges of force generation and displacement. The study also highlights the need for improved PAM fabrication techniques to facilitate the production of identical miniature PAMs for inclusion in muscle bundles.

Refugees in Jordan have an increased burden of cancer due to hard conditions and low income. An increase in awareness of the early signs of cancer could prompt early diagnosis. The current study aims to explore the level of cancer knowledge and barriers to seeking care among Syrian refugees in Jordan. A descriptive cross-sectional survey design was used. Two hundred and forty-one Syrian refugees living in the north of Jordan completed the Cancer Awareness Measure. The mean age was 27.9 (SD 9.1) years, ranging from 18 to 47 years. More than half (56%) of the participants were female. Participants were able to recognize a low number of symptoms (mean 4.4, SD 2.3) and risk factors (4.7 (out of 11), SD 1.9). The most commonly reported barrier was having no medical insurance (83.4%). Refugees' knowledge of symptoms and risk factors was generally unsatisfactory. Barriers to seeking medical care were prevalent. Much work is needed to overcome barriers and enhance knowledge that can hinder early diagnosis and treatment.

Miniature Blimps for Surveillance and Collection of Samples

Jones, Jack

2004-01-01

Miniature blimps are under development as robots for use in exploring the thick, cold, nitrogen atmosphere of Saturn's moon, Titan. Similar blimps can also be used for surveillance and collection of biochemical samples in buildings, caves, subways, and other, similar structures on Earth. The widely perceived need for means to thwart attacks on buildings and to mitigate the effects of such attacks has prompted consideration of the use of robots. Relative to rover-type (wheeled) robots that have been considered for such uses, miniature blimps offer the advantage of ability to move through the air in any direction and, hence, to perform tasks that are difficult or impossible for wheeled robots, including climbing stairs and looking through windows. In addition, miniature blimps are expected to have greater range and to cost less, relative to wheeled robots.

Miniature scientific-grade induction magnetometer for cubesats

2017-04-01

One of the main areas of space research is the study and forecasting of space weather. The society is more and more depending nowadays on satellite technology and communications, so it is vital to understand the physical process in the solar-terrestrial system which may disturb them. Besides the solar radiation and Space Weather effects, the Earth's ionosphere is also modified by the ever increasing industrial activity. There have been also multiple reports relating VLF and ELF wave activity to atmospheric storms and geological processes, such as earthquakes and volcanic activity. For advancing in these fields, the AC magnetic field permanent monitoring is crucial. Using the cubesat technology would allow increasing the number of measuring points dramatically. It is necessary to mention that the cubesats use for scientific research requires the miniaturization of scientific sensors what is a serious problem because the reduction of their dimensions leads, as a rule, to the parameters degradation, especially of sensitivity threshold. Today, there is no basic model of a sensitive miniature induction magnetometer. Even the smallest one of the known - for the Bepi-Colombo mission to Mercury - is too big for cubesats. The goal of the present report is to introduce the new design of miniature three-component sensor for measurement of alternative vector magnetic fields - induction magnetometer (IM). The study directions were concentrated on the ways and possibilities to create the miniature magnetometer with best combination of parameters. For this a set of scientific and technological problems, mostly aimed at the sensor construction improvement, was solved. The most important parameter characterizing magnetometer quality is its own magnetic noise level (NL). The analysis of the NL influencing factors is made and the ways to decrease it are discussed in the report. Finally, the LEMI-151 IM was developed for the SEAM cubesat mission with optimal performances within the

2000-02-01

Polonium 210 distribution in Syrian phosphogypsum and its leaching mechanisms have been evaluated. Radiochemical analysis have shown that 210 Po concentration in Syrian phosphogypsum is always higher than 226 Po concentrations were found to vary between 373 and 589 Bq.Kg -1 with an average value of 471 Bq.Kg -1 , which is lower than those values reported in other countries. 210 Po was found to be more enhanced in smaller particles; a specific activities of 827 Bq.Kg -1 in particles with size less than 250 mesh being observed. Leaching experiments using distilled water have shown that 210 are strongly bounded to phosphogypsum particles. The amount of 210 Po transferred to aqueous media does not exceed 5.6% and 8.4% for batch wise and continuous leaching respectively; lowering the ph has increased this percentage to 20%. In addition, leaching with diluted sulfuric acid indicated that 80% of polonium is present as water insoluble quadrivalent polonium sulphate while 20% as soluble simple polonium sulfate (2PoO 2 .So 3 ). While leaching with selective agents such as MgCl 2 and NH 4 AC have shown that 58% of polonium is present on the surface of gypsum lattice. However, the obtained data could be used to explain environmental pathway of 210 Po from phosphogypsum. (Author)

The problem of vision-guided control of miniature mobile robots is investigated. Untethered mobile robots with small physical dimensions of around 10 cm or less do not permit powerful onboard computers because of size and power constraints. These challenges have, in the past, reduced the functionality of such devices to that of a complex remote control vehicle with fancy sensors. With the help of a computationally more powerful entity such as a larger companion robot, the control loop can be closed. Using the miniature robot's video transmission or that of an observer to localize it in the world, control commands can be computed and relayed to the inept robot. The result is a system that exhibits autonomous capabilities. The framework presented here solves the problem of climbing stairs with the miniature Scout robot. The robot's unique locomotion mode, the jump, is employed to hop one step at a time. Methods for externally tracking the Scout are developed. A large number of real-world experiments are conducted and the results discussed.

Trace elements determination in Syrian honey using x-ray fluorescence technique

Khuder, A.; Ahmad, M.; Saour, G.

2009-05-01

Major and trace elements of S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr in 27 Syrian honey samples, which collected from different areas in the country, in addition to 3 imported honey samples, were determined by dry ashing method for XRF analysis. The samples were diluted and homogenized with a binder made from cellulose powder. The analyzed elements were divided into three groups, relating to the secondary targets used for X-ray excitation. The internal standard method for XRF analysis with a Mo secondary target was used for the determination of the first group of elements: Sr, Rb, Se, As, Zn, Cu, Ni, and Fe. While, the external standard method for XRF analysis with Cu and Ti secondary targets was used for the determination of the second: Mn, Cr, Ti, Ca, K, and third: Cl, and S group of elements, respectively. The results were accurate with a relative standard error less than 4.2 %. The problem of element loss was overcome by the complete drying of honey samples before their ashing. The moisture content was obtained using mass loss and refractive index methods. As a result, the lower limits of detection (LLD) obtained by Mo-XRF was in the range from 0.011 μg Sr/g to 0.064 μg Fe/g, resulting for samples containing 0.1 % ash and collecting live time 1000 s; while, LLD obtained by Cu-XRF was in the range 0.014 μg Mn/g to 0.057 μg K/g. LLD for S and Cl using Ti secondary target was with values of 0.503 μg/g and 1.96 μg/g, respectively. The enhancement factor obtained by drying method for XRF was in the range from 147 to 1667. Normal concentration of elements in Syrian honey was obtained. The concentration of elements was comparable to those obtained by other workers for honeys in different countries. Elements of K, Ca, and Cl were predominantly distributed in all Syrian honey samples. Elements of Sr, Zn, Cu, Fe, Ti, and S were well distributed in all honey samples. While, the concentrations of Rb, Ni, Mn, Cr elements in some honey samples were below the

Miniaturization leads to considerable reorganization of structures in insects, affecting almost all organs and tissues. In the smallest insects, comparable in size to unicellular organisms, modifications arise not only at the level of organs, but also at the cellular level. Miniaturization is accompanied by allometric changes in many organ systems. The consequences of miniaturization displayed by different insect taxa include both common and unique changes. Because the smallest insects are among the smallest metazoans and have the most complex organization among organisms of the same size, their peculiar structural features and the factors that limit their miniaturization are of considerable theoretical interest to general biology.

Science.gov (United States)

Li, Songsheng; Zhang, Guoye; Chen, Bin; Shen, Yuan

2017-07-01

The working performances of miniature ball bearings are obviously affected by its’ geometric structure parameters. In this paper, quasi-static analysis theory is applied in the design of miniature ball bearings. Firstly, it is studied the influence of geometry structure, preload and rotating speed on the dynamic performance of bearing. Secondly, bearing dynamic characteristics are analyzed which include the bearing stiffness and Spin to roll Ratio. Lastly, the contact stress and bearing life are calculated. The results indicate that structure parameters play an importance role in bearing’s dynamic performances. Miniature ball bearings which have lager ball number, bigger ball diameter and smaller inner race groove radius can get better performances while velocity and preload have great impact on the bearing life. So that parameters of miniature bearing should be chosen cautiously.

Use of miniature tensile specimen and video extensometer for measurement of mechanical properties

International Nuclear Information System (INIS)

Kumar, Kundan; Pooleery, Arun; Madhusoodanan, K.

2014-08-01

Miniaturisation of the tensile test specimen below the sub-size level poses various challenges, such as conformity of specimen to various acceptance criteria as per standard test specimen, aspect ratio, minimum number of grains required in a gauge cross-section, fabrication for uniformity in metrological values, etc. Apart from these, measurement of strain over a very limited available space on the test specimen is another practical challenge. Despite these limitations, miniature specimen testing is increasingly being used worldwide these days. The driving forces behind increasing use of miniature test techniques are new material development, assuring fitness of component after in-service-inspection, low dose of radiation exposure due to smaller dimensions of test specimens etc. However, the evaluation of mechanical properties from a miniature tensile test has a greater advantage over the other miniature novel test techniques, such as small punch test, ABI, miniature fatigue and impact tests etc., as it is a direct method of measurement of mechanical properties. This report covers various aspects of miniature tensile test methodologies, which include geometrical design of specimen having gauge length of 3-5 mm, fabrication, development of special fixtures for gripping the test specimens, and use of optical method for strain measurement. The geometrical design of the specimen and its behaviour over application of tensile load has been established using FEM analysis. A good agreement between conventional and miniature test results exemplifies the potential of the miniature tensile test technique. (author)

Pasini, Silvia; Bianchi, Elena; Dubini, Gabriele; Cortelezzi, Luca

2017-11-01

Computational fluid dynamic (CFD) simulations allowed us to conceive and design a miniaturized inertial impactor able to collect fine airborne particulate matter (PM10, PM2.5 and PM1). We created, by 3D printing, a prototype of the impactor. We first performed a set of experiments by applying a suction pump to the outlets and sampling the airborne particulate of our laboratory. The analysis of the slide showed a collection of a large number of particles, spanning a wide range of sizes, organized in a narrow band located below the exit of the nozzle. In order to show that our miniaturized inertial impactor can be truly used as a personal air-quality monitor, we performed a second set of experiments where the suction needed to produce the airflow through the impactor is generated by a human being inhaling through the outlets of the prototype. To guarantee a number of particles sufficient to perform a quantitative characterization, we collected particles performing ten consecutive deep inhalations. Finally, the potentiality for realistic applications of our miniaturized inertial impactor used in combination with a miniaturized single-particle detector will be discussed.

2016-01-01

Given the large burden of non-communicable diseases (NCDs) among both Syrian refugees and the host communities within which they are settled, humanitarian actors and the government of Lebanon face immense challenges in addressing health needs. This study assessed health status, unmet needs, and utilization of health services among Syrian refugees and host communities in Lebanon. A cross-sectional survey of Syrian refugees and host communities in Lebanon was conducted using a two-stage cluster survey design with probability proportional to size sampling. To obtain information on chronic NCDs, respondents were asked a series of questions about hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and arthritis. Differences in household characteristics by care-seeking for these conditions were examined using chi-square, t-test, and adjusted logistic regression methods. Over half (50.4 %) of refugee and host community households (60.2 %) reported a member with one of the five NCDs. Host community prevalence rates were significantly higher than refugees for all conditions except chronic respiratory diseases ( p  = 0.08). Care-seeking for NCDs among refugees and host community households was high across all conditions with 82.9 and 97.8 %, respectively, having sought care in Lebanon for their condition. Refugees utilized primary health care centers (PHCC) (57.7 %) most often while host communities sought care most in private clinics (62.4 %). Overall, 69.7 % of refugees and 82.7 % of host community members reported an out-of-pocket consultation payment ( p  = 0.041) with an average payment of US$15 among refugees and US$42 for the host community ( p Syrian crisis and the burden on the Lebanese health system, implications for both individuals with NCDs and Lebanon's health system are immense. The burden of out of pocket expenses on persons with NCDs are also substantial, especially given the tenuous economic status of many refugees

From the experimental and theoretical studies made upon the BONNER's spheres System with a I 6 Li(Eu) crystal and with a miniaturized 3 He counter we get the normalized energy response functions R*sub(i)(E). This normalization is obtained by the mathematization of the Resolution Function R*(i,E) in the Log-Normal distribution hypothesis to mono energetic neutrons given in April 1976 to the International Symposium on Californium 252. The fit of the Log-Normal Hypothesis with the experimental and Theoretical data is very satisfactory. The parameter's tabulated values allow a precise interpolation, at all energies between 0.4 eV and 15 MeV and for all spheres diameters between 2 and 12 inches, of the discretized R*sub(ij) Reference Matrix for the applications to neutron dosimetry and spectrometry [fr

2012-01-01

To develop the fatigue life evaluation technique using miniature specimen, the investigation of the effect of specimen size and specimen shape on the fatigue life and the development of the fatigue testing machine, especially the extensometer, were carried out. The effect of specimen size on the fatigue life was almost negligible for the round-bar specimens. The shorter fatigue life at relatively low strain range conditions for the hourglass specimen that the standard specimen were observed. Therefore the miniature round-bar specimen was considered to be adequate for the fatigue life evaluation using small specimen. Several types of the extensometer system using a strain gauge and a laser has been developed for realizing the fatigue test of the miniature round-bar specimen at high temperature in vacuum.

Ongoing armed conflict in Syria has caused large scale displacement. Approximately half of the population of Syria have been displaced including the millions living as refugees in neighboring countries. We sought to assess the health and nutrition of Syrian refugees affected by the conflict. Representative cross-sectional surveys of Syrian refugees were conducted between October 2 and November 30, 2013 in Lebanon, April 12 and May 1, 2014 in Jordan, and May 20 and 31, 2013 in Iraq. Surveys in Lebanon were organized in four geographical regions (North, South, Beirut/Mount Lebanon and Bekaa). In Jordan, independent surveys assessed refugees residing in Za'atri refugee camp and refugees residing among host community nationwide. In Iraq, refugees residing in Domiz refugee camp in the Kurdistan region were assessed. Data collected on children aged 6 to 59 months included anthropometric indicators, morbidity and feeding practices. In Jordan and Lebanon, data collection also included hemoglobin concentration for children and non-pregnant women aged 15 to 49 years, anthropometric indicators for both pregnant and non-pregnant women, and household level indicators such as access to safe water and sanitation. The prevalence of global acute malnutrition among children 6 to 59 months of age was less than 5 % in all samples (range 0.3-4.4 %). Prevalence of acute malnutrition among women 15 to 49 years of age, defined as mid-upper arm circumference less than 23.0 cm, was also relatively low in all surveys (range 3.5-6.5 %). For both children and non-pregnant women, anemia prevalence was highest in Za'atri camp in Jordan (48.4 % and 44.8 %, respectively). Most anemia was mild or moderate; prevalence of severe anemia was less than or equal to 1.1 % in all samples of children and women. Despite the ongoing conflict, results from all surveys indicate that global acute malnutrition is relatively low in the assessed Syrian refugee populations. However, prevalence of anemia

Ferrets and mice are frequently used as animal models for influenza research. However, ferrets are demanding in terms of housing space and handling, whereas mice are not naturally susceptible to infection with human influenza A or B viruses. Therefore, prior adaptation of human viruses is required for their use in mice. In addition, there are no mouse-adapted variants of the recent H3N2 viruses, because these viruses do not replicate well in mice. In this study, we investigated the susceptibility of Syrian hamsters to influenza viruses with a view to using the hamster model as an alternative to the mouse model. We found that hamsters are sensitive to influenza viruses, including the recent H3N2 viruses, without adaptation. Although the hamsters did not show weight loss or clinical signs of H3N2 virus infection, we observed pathogenic effects in the respiratory tracts of the infected animals. All of the H3N2 viruses tested replicated in the respiratory organs of the hamsters, and some of them were detected in the nasal washes of infected animals. Moreover, a 2009 pandemic (pdm09) virus and a seasonal H1N1 virus, as well as one of the two H3N2 viruses, but not a type B virus, were transmissible by the airborne route in these hamsters. Hamsters thus have the potential to be a small-animal model for the study of influenza virus infection, including studies of the pathogenicity of H3N2 viruses and other strains, as well as for use in H1N1 virus transmission studies. IMPORTANCE We found that Syrian hamsters are susceptible to human influenza viruses, including the recent H3N2 viruses, without adaptation. We also found that a pdm09 virus and a seasonal H1N1 virus, as well as one of the H3N2 viruses, but not a type B virus tested, are transmitted by the airborne route in these hamsters.

Miniature Schnauzer dogs are predisposed to idiopathic hypertriglyerceridemia, which increases risk for diseases such as pancreatitis and gallbladder mucocele. Recently, elevated triglyceride concentrations have been associated with proteinuria in this breed, although it is difficult to determine which abnormality is primary. Retrospective review of renal tissue from 27 proteinuric Miniature Schnauzers revealed that 20 dogs had ultrastructural evidence of osmophilic globules consistent with lipid in glomerular tufts. Seven of these dogs had lipid thromboemboli in glomerular capillary loops that distorted their shape and compressed circulating erythrocytes. Triglyceride concentrations were reported in 6 of these 7 dogs, and all were hypertriglyceridemic. In addition, glomerular lipidosis (defined as accumulation of foam cells within peripheral capillary loops) was identified in a single dog. The remaining 12 dogs had smaller amounts of lipid that could only be identified ultrastructurally. Neither signalment data nor clinicopathologic parameters (serum albumin, serum creatinine, urine protein-to-creatinine ratio, and blood pressure) differed among the various types of lipid lesions. During the time course of this study, all dogs diagnosed with glomerular lipid thromboemboli were Miniature Schnauzers, underscoring the importance of recognizing these clear spaces within capillary loops as lipid.

Three miniature sheet-type tensile specimens and a miniature rod-type specimen are being used to determine irradiated tensile properties for alloy development for fusion reactors. The tensile properties of type 316 stainless steel were determined with these different specimens, and the results were compared. Reasonably good agreement was observed. However, there were differences that led to recommendations on which specimens are preferred. 4 references, 9 figures, 6 tables

Analysis of nonlinear elastic behavior in miniature pneumatic artificial muscles

Hocking, Erica G.; Wereley, Norman M.

2013-01-01

Pneumatic artificial muscles (PAMs) are well known for their excellent actuator characteristics, including high specific work, specific power, and power density. Recent research has focused on miniaturizing this pneumatic actuator technology in order to develop PAMs for use in small-scale mechanical systems, such as those found in robotic or aerospace applications. The first step in implementing these miniature PAMs was to design and characterize the actuator. To that end, this study presents the manufacturing process, experimental characterization, and analytical modeling of PAMs with millimeter-scale diameters. A fabrication method was developed to consistently produce low-cost, high performance, miniature PAMs using commercially available materials. The quasi-static behavior of these PAMs was determined through experimentation on a single actuator with an active length of 39.16 mm (1.54 in) and a diameter of 4.13 mm (0.1625 in). Testing revealed the PAM’s full evolution of force with displacement for operating pressures ranging from 207 to 552 kPa (30-80 psi in 10 psi increments), as well as the blocked force and free contraction at each pressure. Three key nonlinear phenomena were observed: nonlinear PAM stiffness, hysteresis of the force versus displacement response for a given pressure, and a pressure deadband. To address the analysis of the nonlinear response of these miniature PAMs, a nonlinear stress versus strain model, a hysteresis model, and a pressure bias are introduced into a previously developed force balance analysis. Parameters of these nonlinear model refinements are identified from the measured force versus displacement data. This improved nonlinear force balance model is shown to capture the full actuation behavior of the miniature PAMs at each operating pressure and reconstruct miniature PAM response with much more accuracy than previously possible.

2013-03-01

The development of internet of things has brought new opportunities and challenges to the application of RFID tags. Moreover, the Miniaturization application trend of tags at present has become the mainstream of development. In this paper, the double-layer design is to reduce the size of HF antenna, and the magnetic null point of magnetic reconnection region between the RLC resonant circuit and the reader provides sufficient energy to the miniaturization of antenna. The calculated and experimental results show that the miniaturization of HF antennas can meet the reading and writing requirement of the international standard ISO/IEC14443 standard. The results of this paper may make a positive contribution to the applications of RFID technology.

Radon concentrations in groundwater were measured from six monitoring stations that were distributed along the Syrian rift valley, with time intervals of one month over a span of more than six years from 1992 to 1998. This set of data was integrated and statistically handled in order to be used as a significant base for estimating the range of natural radon background variations in groundwater along the concerned zone. The results reveal that only few anomalous radon values were recorded during the given time-window, which might be caused by tectonic disturbances or otherwise in the study region. (author)

Al-Masri, M. S.; Shwekani, R.; Jerbi, B.; Awad, I.

2006-06-01

In the present study, exposure levels and radon concentrations have been measured in natural gas production lines at the Syrian gas company. The study area includes gas stations for directories of Der Ezzor, Al-Jbessa, Al-Hassaka, and the middle region. The results showed that radiation exposure rates in remote stations and internal stations were within the natural levels except for two main locations, viz reflex pumps and propane production unites; 3 μSvhr -1 was reported. Radon concentration in Syrian natural gas varied between 15.4 Bqm - 3 and 1141 Bqm - 3; coproduced natural gas was found to contain higher concentration that the free natural gas. In addition, radon concentrations were higher in the central processing facilities that the well heads; these high levels are due to pressurizing and concentrating processes that enhance radon gas and its daughters concentrations in these stations. Moreover, a value of 659 Bqm - 3 in Al-Jbessa directorate gas and 225 Bqm - 3 in Al-Hassaka directorate gas were reported. While the concentration was lower in gas producing safur; a value of 80 Bqm - 3 was observed. On the other hand, maximum radon gas concentrations and its daughters in workplace air environment was found to be relatively high in the gas analysis laboratory and they are due to gas release inside the lab during analysis in addition to good separation of these laboratories from the surrounding environment.

Blocking oxytocin receptors inhibits vaginal marking to male odors in female Syrian hamsters.

Science.gov (United States)

Martinez, Luis A; Albers, H Elliott; Petrulis, Aras

2010-12-02

In Syrian hamsters (Mesocricetus auratus), precopulatory behaviors such as vaginal scent marking are essential for attracting a suitable mate. Vaginal marking is dependent on forebrain areas implicated in the neural regulation of reproductive behaviors in rodents, including the medial preoptic/anterior hypothalamus (MPOA-AH). Within MPOA-AH, the neuropeptide oxytocin (OT) acts to facilitate copulation (lordosis), as well as ultrasonic vocalizations towards males. It is not known, however, if OT in this area also facilitates vaginal marking. In the present study, a specific oxytocin receptor antagonist (OTA) was injected into MPOA-AH of intact female Syrian hamsters to determine if oxytocin receptor-dependent signaling is critical for the normal expression of vaginal marking elicited by male, female, and clean odors. OTA injections significantly inhibited vaginal marking in response to male odors compared with vehicle injections. There was no effect of OTA on marking in response to either female or clean odors. When injected into the bed nucleus of the stria terminalis (BNST), a nearby region to MPOA-AH, OTA was equally effective in decreasing marking. Finally, the effects of OTA appear to be specific to vaginal marking, as OTA injections in MPOA-AH or BNST did not alter general locomotor activity, flank marking, or social odor investigation. Considered together, these results suggest that OT in MPOA-AH and/or BNST normally facilitates male odor-induced vaginal marking, providing further evidence that OT generally supports prosocial interactions among conspecifics.

The purpose of this study was to evaluate the cationic trypsinogen gene in miniature schnauzers for possible mutations. Genetic mutations have been linked with hereditary pancreatitis in humans. Four miniature schnauzers were selected on the basis of a clinical history of pancreatitis. One healthy miniature schnauzer and 1 healthy mixed breed canine were enrolled as controls. DNA was extracted from these canines using a commercial kit. Primers were designed to amplify the entire canine cationic trypsinogen cDNA sequence. A polymerase chain reaction (PCR) was performed and products were purified and sequenced. All sequences were then compared. The healthy control canine, a healthy miniature schnauzer, and the 4 miniature schnauzers with pancreatitis showed identical sequences of the cationic trypsinogen gene to the published sequence. We conclude that, in contrast to humans with hereditary pancreatitis, mutations of the cationic trypsinogen gene do not play a major role in the genesis of pancreatitis in the miniature schnauzer.

2012-01-01

The Monte Carlo method, using the MCNP4C code, was used in this paper to calculate the power distribution in 3-D geometry in the fuel rods of the Syrian Miniature Neutron Source Reactor (MNSR). To normalize the MCNP4C result to the steady state nominal thermal power, the appropriate scaling factor was defined to calculate the power distribution precisely. The maximum power of the individual rod was found in the fuel ring number 2 and was found to be 105 W. The minimum power was found in the fuel ring number 9 and was 79.9 W. The total power in the total fuel rods was 30.9 k W. This result agrees very well with nominal power reported in the reactor safety analysis report which equals 30 k W. Finally, the peak power factors, which are defined as the ratios between the maximum to the average and the maximum to the minimum powers were calculated to be 1.18 and 1.31 respectively. (author)

The aim of our study was to investigate the clinical and histopathological characteristics of cutaneous leishmaniasis (CL) in the city of Sanliurfa in Turkey, where Syrian refugees also reside. At the Harran University Hospital outpatient clinics between 2012 and 2013, 54 CL cases, including 24 Syrian patients, underwent punch biopsy of the skin and/or a touch imprint. Patients in whom leishmania parasites were detected were included in the study. The clinical and histopathological data of the patients were obtained by a review of the patients' medical records. All the slides of each patient were re-evaluated histopathologically. Fifty-four cases (mean age; 17 ± 12 years), consisting of 32 males (59.3%) and 22 females (40.7%), were examined. The most common site of involvement was the face (63%). The most common presentation was noduloulcerative lesions (57.4%). Histopathologically, the majority of the cases exhibited hyperkeratosis, follicular plugging of the epidermis, chronic inflammatory infiltration, leishmania amastigotes and non-caseating granulomatous inflammation in the dermis. CL presents with a wide spectrum of expression, both clinically and histologically, and may mimic other inflammatory and neoplastic diseases. The diagnosis of CL relies on the identification of leishmania amastigotes in either a direct smear of the lesion or in a tissue section.

The aim of our studies was to elucidate the biochemical mechanisms responsible for the differences in the biological half life of actinides in the liver of different mammalian species. Rats and mice were chosen as models for rapid elimination, and Syrian and Chinese hamsters as models for slow elimination. To distinguish between fixation in lysosomes and mitochondria, the lysosomes were isolated following injection of Triton WR1339 6 days after 239 Pu administration. The animals were sacrificed 4 days later. In order to study the possible association with ferritin, 59 Fe was also injected. Liver homogenates were subjected to differential and isopycnic centrifugation in a sucrose density gradient. The typical shift in the density of the lysosomal marker acid phosphatase from rho approximately 1.2 to rho approximately 1.1 following Triton WR1339 injection was observed in all species. It was possible therefore to separate lysosomes from other cell organelles, especially mitochondria. It was concluded that: 1) Mitochondria can virtually be excluded as binding sites in all four species; 2) Lysosomes are one important storage site in rats, mice and Syrian hamsters; 3) If 239 Pu is bound to another cell constituent in addition to lysosomes in the hamster species (which is not yet proven) its density should be approximately 1.17.

Full Text Available The association between increasing obesity and metabolic syndrome among adolescent and the adverse consequences in adulthood including type-2 diabetes and coronary heart disease is well documented. The main objectives of this study were to evaluate the major metabolic risk factors and some clinical important parameters in Syrian male adolescents (18-19 years old, and to assess the correlations between BF% determined by BIA-man prediction equation and metabolic risk factors in the same group. The correlations between body fat percentage (BF% based on BIA-man predictive equations, blood pressure, fasting blood sugar (FBS, cholesterol (Chol, low density lipoprotein cholesterol (LDL-C, high density lipoprotein cholesterol (HDL-C, triglycerides (TG, Hematocrit (Ht, and hemoglobin (Hb in 1596 healthy Syrian adolescents aged 18-19 years and the mean values of these parameters were examined. Data showed that, DBP, Chol, TG, LDL and TG/HDL-C were significantly (p<0.05 higher in overweight and obese subjects in compression to normal weight cases. Whereas, SBP, FBS and Ht were significantly (p<0.05 higher in obese subjects in compression to normal weight. However, all measured variable related to metabolic syndrome risk factors increased with increasing the BF% determined by BIA-man. The present study suggests that % BF by BIA-man is a good predictor of metabolic risks factors for Syrian adolescents.

Full Text Available Two people, from two different cultural backgrounds, with two different pasts, meet each other. The following article deals with the process of these two people´s becoming acquainted. Two years ago, Omar Khir Alanam was forced to leave his native Syria; he eventually arrived in Austria. In the spring of 2015, we met in Graz. We got together frequently, talked about everyday life and Syrian food. However, we never talked about our pasts. After a van attack in Graz on 20 June 2015, in which three people were killed and several badly injured, we became aware of how differently this affected us. Only then, after this horrible incident, did our individual pasts which colored our perceptions of the event become a major topic of interviews and discussions. During the process, the research took on a dialogic character. Only the mutual interest in the seemingly foreign enabled us to understand each other.

Laser direct marking applied to rasterizing miniature Data Matrix Code on aluminum alloy

2016-03-01

Precise miniaturization of 2D Data Matrix (DM) Codes on Aluminum alloy formed by raster mode laser direct part marking is demonstrated. The characteristic edge over-burn effects, which render vector mode laser direct part marking inadequate for producing precise and readable miniature codes, are minimized with raster mode laser marking. To obtain the control mechanism for the contrast and print growth of miniature DM code by raster laser marking process, the temperature field model of long pulse laser interaction with material is established. From the experimental results, laser average power and Q frequency have an important effect on the contrast and print growth of miniature DM code, and the threshold of laser average power and Q frequency for an identifiable miniature DM code are respectively 3.6 W and 110 kHz, which matches the model well within normal operating conditions. In addition, the empirical model of correlation occurring between laser marking parameters and module size is also obtained, and the optimal processing parameter values for an identifiable miniature DM code of different but certain data size are given. It is also found that an increase of the repeat scanning number effectively improves the surface finish of bore, the appearance consistency of modules, which has benefit to reading. The reading quality of miniature DM code is greatly improved using ultrasonic cleaning in water by avoiding the interference of color speckles surrounding modules.

Voluntary exercise increases resilience to social defeat stress in Syrian hamsters.

2018-05-01

Exposure to social stressors can cause profound changes in an individual's well-being and can be an underlying factor in the etiology of a variety of psychopathologies, such as post-traumatic stress disorder (PTSD). In Syrian hamsters, a single social defeat experience results in behavioral changes collectively known as conditioned defeat (CD), and includes an abolishment of territorial aggression and the emergence of high levels of defensive behaviors. In contrast, voluntary exercise has been shown to promote stress resilience and can also have anxiolytic-like effects. Although several studies have investigated the resilience-inducing effects of voluntary exercise after exposure to physical stressors, such as restraint and electric shock, few studies have examined whether exercise can impart resilience in response to ethologically-based stressors, such as social defeat. In Experiment 1, we tested the hypothesis that voluntary exercise can have anxiolytic-like effects in socially defeated hamsters. In the elevated plus maze, the exercise group exhibited a significant reduction in risk assessment, a commonly used index of anxiety, compared to the no-exercise group. In the open-field test, animals in the exercise group exhibited a significant reduction in locomotor behavior and rearing, also an indication of an anxiolytic-like effect of exercise. In Experiment 2, we examined whether exercise can reverse the defeat-induced potentiation of defensive behaviors using the CD model. Socially defeated hamsters in the exercise group exhibited significantly lower levels of defensive/submissive behaviors compared to the no-exercise group upon exposure to the resident aggressor. Taken together, these results are among the first to suggest that voluntary exercise may promote resilience to social defeat stress in Syrian hamsters. Copyright © 2018 Elsevier Inc.

Ceramics research in a high-energy neutron source

International Nuclear Information System (INIS)

Clinard, F.W. Jr.

1989-01-01

The studies on the irradiation effect to ceramics have added much to the basic understanding of their behavior, for example, the amorphous state of ceramics related to radiation-induced metamictization, the radiation-induced strengthening and toughening due to ultrafine defect aggregates, the in situ degradation of electrical resistivity, the role of radiation-induced defects on thermal conductivity and so on. Most of the irradiation testing on ceramics in the fields of structural and thermal properties have been carried out by using fast fission neutrons of about 1 MeV, but if this energy could be significantly changed, the size and nature of damage cascade and the quantity of transmutation gases produced would change. The significance of neutron source parameters, the special test requirement for ceramics such as the use of miniature specimens, the control of test environment, the transient reduction of electrical resistivity and so on are discussed. A special case of ceramic studies is that on new oxide superconductors. These materials can be made into amorphous state at about 1 dpa using 1 MeV electrons, and are considered to be fairly damage-sensitive. (K.I.)

Since the civilian war in Syria began, thousands of seriously injured trauma patients from Syria were brought to Turkey for emergency operations and/or postoperative intensive care. The aim of this study was to present the demographics and clinical features of the wounded patients in Syrian civil war admitted to the surgical intensive care units in a tertiary care centre. The records of 80 trauma patients admitted to the Anaesthesia, General Surgery and Neurosurgery ICUs between June 1, 2012 and July 15, 2014 were included in the study. The data were reviewed regarding the demographics, time of presentation, place of reference, Acute Physiology and Chronic Health Evaluation II (APACHE II) score and Injury Severity Score (ISS), surgical procedures, complications, length of stay and mortality. A total of 80 wounded patients (70 males and 10 females) with a mean age of 28.7 years were admitted to surgical ICUs. The most frequent cause of injury was gunshot injury. The mean time interval between the occurrence of injury and time of admission was 2.87 days. Mean ISS score on admission was 21, and mean APACHE II score was 15.7. APACHE II scores of non-survivors were significantly increased compared with those of survivors (P=0.001). No significant differences was found in the age, ISS, time interval before admission, length of stay in ICU, rate of surgery before or after admission. The most important factor affecting mortality in this particular trauma-ICU patient population from Syrian civil war was the physiological condition of patients on admission. Rapid transport and effective initial and on-road resuscitation are critical in decreasing the mortality rate in civil wars and military conflicts.

Full Text Available Alternative methods to the utilization of laboratory animal blood and its by-products are particularly attractive, especially regarding hamsters due to their small size and difficulties in obtaining serial blood samples. Steroid hormone metabolite quantification in feces, widely used in studies of free-ranging or intractable animals, is a non-invasive, non-stressor, economical, and animal saving technique which allows longitudinal studies by permitting frequent sampling of the same individual. The present study was undertaken to determine the suitability of this method for laboratory animals. Estradiol and progesterone metabolites were quantified by radioimmunoassay in feces of intact, sexually mature female Syrian hamsters during the estrous cycle (control and in feces of superovulated females. Metabolites were extracted by fecal dilution in ethanol and quantified by solid phase radioimmunoassay. Median estrogen and progesterone concentrations were 9.703 and 180.74 ng/g feces in the control group, respectively. Peaks of estrogen (22.44 ± 4.54 ng/g feces and progesterone (655.95 ± 129.93 ng/g feces mean fecal concentrations respectively occurred 12 h before and immediately after ovulation, which is easily detected in this species by observation of a characteristic vaginal postovulatory discharge. Median estrogen and progesterone concentrations (28.159 and 586.57 ng/g feces, respectively were significantly higher in superovulated animal feces (P < 0.0001. The present study demonstrated that it is possible to monitor ovarian activity in Syrian hamsters non-invasively by measuring fecal estradiol and progesterone metabolites. This technique appears to be a quite encouraging method for the development of new endocrinologic studies on laboratory animals.

We report a demonstration of a very small microwave atomic clock using the 12.6 GHz hyperfine transition of the trapped {sup 171}Yb ions inside a miniature, completely sealed-off 3 cm{sup 3} ion-trap vacuum package. In the ion clock system, all of the components are highly miniaturized with low power consumption except the 369 nm optical pumping laser still under development for miniaturization. The entire clock, including the control electronics, consumes <300 mW. The fractional frequency instability of the miniature Yb{sup +} clock reaches the 10{sup -14} range after a few days of integration.

The miniaturization of spectrometer can broaden the application area of spectrometry, which has huge academic and industrial value. Among various miniaturization approaches, filter-based miniaturization is a promising implementation by utilizing broadband filters with distinct transmission functions. Mathematically, filter-based spectral reconstruction can be modeled as solving a system of linear equations. In this paper, we propose an algorithm of spectral reconstruction based on sparse optimization and dictionary learning. To verify the feasibility of the reconstruction algorithm, we design and implement a simple prototype of a filter-based miniature spectrometer. The experimental results demonstrate that sparse optimization is well applicable to spectral reconstruction whether the spectra are directly sparse or not. As for the non-directly sparse spectra, their sparsity can be enhanced by dictionary learning. In conclusion, the proposed approach has a bright application prospect in fabricating a practical miniature spectrometer.

Full Text Available Andes virus (ANDV is highly pathogenic in humans and is the primary etiologic agent of hantavirus cardiopulmonary syndrome (HCPS in South America. Case-fatality rates are as high as 50% and there are no approved vaccines or specific therapies for infection. Our laboratory has recently developed a replication-competent recombinant vesicular stomatitis virus (VSV-based vaccine that expressed the glycoproteins of Andes virus in place of the native VSV glycoprotein (G. This vaccine is highly efficacious in the Syrian hamster model of HCPS when given 28 days before challenge with ANDV, or when given around the time of challenge (peri-exposure, and even protects when administered post-exposure. Herein, we sought to test the durability of the immune response to a single dose of this vaccine in Syrian hamsters. This vaccine was efficacious in hamsters challenged intranasally with ANDV 6 months after vaccination (p = 0.025, but animals were not significantly protected following 1 year of vaccination (p = 0.090. The decrease in protection correlated with a reduction of measurable neutralizing antibody responses, and suggests that a more robust vaccination schedule might be required to provide long-term immunity.

2018-01-01

Tensile and creep properties of new austenitic steel Sanicro 25 at room temperature and operating temperature 700 °C were investigated by testing on miniature specimens. The results were correlated with testing on conventional specimens. Very good agreement of results was obtained, namely in yield and ultimate strength, as well as short-term creep properties. Although the creep rupture time was found to be systematically shorter and creep ductility lower in the miniature test, the minimum creep rates were comparable. The analysis of the fracture surfaces revealed similar ductile fracture morphology for both specimen geometries. One exception was found in a small area near the miniature specimen edge that was cut by electro discharge machining, where an influence of the steel fracture behavior at elevated temperature was identified.

1986-01-01

The measurement of total body fat is of importance in studies of nutritional assessment, dietary regimens, and for the management of obesity. In the past, fat has been determined either by anthropometric methods, which introduce high uncertainties, or by model-dependent estimation of fat-free tissue. The validity, however, of the different models in disease is questionable. Total body carbon measurements provide a more direct evaluation of body fat both in normal subjects and in patients. The authors present here a facility for carbon measurements without the use of a major accelerator. The same facility can be used for the measurement of other major body elements and for the evaluation of the body's compartments. Carbon is measured in vivo through neutron inelastic scattering, by detecting the 4.44 MeV gamma rays. A miniature (10 cm long) 14 MeV D-T neutron generator is used. The short half-life of the 4.44 MeV state of carbon requires detection of the gamma rays simultaneously with the 10 μs neutron pulse. Generators with low pulsing rate were found inappropriate for carbon measurement because of their low duty-cycle (high neutron output during pulse). The detection system consists of NaI(T1) detectors and fast electronics for handling the high even rate during the neutron pulse. A description of the facility and an evaluation of the technique will be presented

Miniature specimen technology for postirradiation fatigue crack growth testing

1979-01-01

Current magnetic fusion reactor design concepts require that the fatigue behavior of candidate first wall materials be characterized. Fatigue crack growth may, in fact, be the design limiting factor in these cyclic reactor concepts given the inevitable presence of crack-like flaws in fabricated sheet structures. Miniature specimen technology has been developed to provide the large data base necessary to characterize irradiation effects on the fatigue crack growth behavior. An electrical potential method of measuring crack growth rates is employed on miniature center-cracked-tension specimens (1.27 cm x 2.54 cm x 0.061 cm). Results of a baseline study on 20% cold-worked 316 stainless steel, which was tested in an in-cell prototypic fatigue machine, are presented. The miniature fatigue machine is designed for low cost, on-line, real time testing of irradiated fusion candidate alloys. It will enable large scale characterization and development of candidate first wall alloys

This study examined the inter-relationship between trauma centrality, self-efficacy, posttraumatic stress disorder (PTSD) and psychiatric co-morbidity among a group of Syrian refugees living in Turkey, and whether gender would moderate the mediational effect of self-efficacy on the impact of trauma centrality on distress. Seven hundred and ninety-two Syrian refugees completed the Harvard Trauma Questionnaire, General Health Questionnaire-28, Centrality of Event Scale and Generalized Self-Efficacy Scale. The results showed that 52% met the cutoff for PTSD. Trauma centrality was positively correlated with PTSD, psychiatric co-morbidity and self-efficacy. Self-efficacy was negatively correlated with PTSD only. Gender did not moderate the mediational effect of self-efficacy on the path between trauma centrality and distress outcomes. To conclude, following exposure to traumatic events, more than half reported PTSD. Perception of the future and identity construction was affected. Signs of psychological distress were evident, alongside resilience, regardless of gender. Copyright © 2017 Elsevier Ltd. All rights reserved.

Ebola hemorrhagic fever (EHF) is a severe viral infection for which no effective treatment or vaccine is currently available. While the nonhuman primate (NHP) model is used for final evaluation of experimental vaccines and therapeutic efficacy, rodent models have been widely used in ebolavirus research because of their convenience. However, the validity of rodent models has been questioned given their low predictive value for efficacy testing of vaccines and therapeutics, a result of the inconsistent manifestation of coagulopathy seen in EHF. Here, we describe a lethal Syrian hamster model of EHF using mouse-adapted Ebola virus. Infected hamsters displayed most clinical hallmarks of EHF, including severe coagulopathy and uncontrolled host immune responses. Thus, the hamster seems to be superior to the existing rodent models, offering a better tool for understanding the critical processes in pathogenesis and providing a new model for evaluating prophylactic and postexposure interventions prior to testing in NHPs.

Full Text Available The article deals with pictorial metamorphosis in the opening pages of two early 14th-century manuscripts of the Estoire del saint Graal. Firstly, the episodes depicted are analysed iconographically and formally. Secondly, it explores how pictorial narrative is established in the multi-compartmentalised miniature, that is how the images are linked internally in order to convey a narrative that has its beginning and its ending. Thirdly, it is shown how the images in the opening miniature communicate with other miniatures in the manuscript and how the course of interpretation, signaled by the opening miniature, is succeeded and confirmed by the selection of episodes which are subsequently depicted, as well as by the way in which the episodes depicted are pictorially interpreted.

Full Text Available New World arenaviruses cause fatal hemorrhagic disease in South America. Pirital virus (PIRV, a mammarenavirus hosted by Alston’s cotton rat (Sigmodon alstoni, causes a disease in Syrian golden hamsters (Mesocricetus auratus (biosafety level-3, BSL-3 that has many pathologic similarities to the South American hemorrhagic fevers (BSL-4 and, thus, is considered among the best small-animal models for human arenavirus disease. Here, we extend in greater detail previously described clinical and pathological findings in Syrian hamsters and provide evidence for a pro-inflammatory macrophage response during PIRV infection. The liver was the principal target organ of the disease, and signs of Kupffer cell involvement were identified in mortally infected hamster histopathology data. Differential expression analysis of liver mRNA revealed signatures of the pro-inflammatory response, hematologic dysregulation, interferon pathway and other host response pathways, including 17 key transcripts that were also reported in two non-human primate (NHP arenavirus liver-infection models, representing both Old and New World mammarenavirus infections. Although antigen presentation may differ among rodent and NHP species, key hemostatic and innate immune-response components showed expression parallels. Signatures of pro-inflammatory macrophage involvement in PIRV-infected livers included enrichment of Ifng, Nfkb2, Stat1, Irf1, Klf6, Il1b, Cxcl10, and Cxcl11 transcripts. Together, these data indicate that pro-inflammatory macrophage M1 responses likely contribute to the pathogenesis of acute PIRV infection.

In recent years the use of miniature and/or microscale versions of the more popular mass spectrometers have been realised. This has led to the development of portable analytical devices for a range of 'in the field' sensing applications in aerospace, environmental monitoring, medical diagnosis and process control. In this paper the principles underpinning the development of miniature quadrupole mass spectrometers are reviewed. Two different microfabrication methods are compared with a conventional QMS used for residual gas analysis in the range 1-100 Da.

The suitability of Syrian Portland cement for disposal of solidified low-level radioactive waste was assessed by measuring the leaching rate of 134 Cs. In ordinary cement concrete, a leaching rate of 1.309 x 10 -3 g/cm 2 per day was measured. Mixing this concrete with microsilica reduced significantly the leaching rate to 3.106 x 10 -4 g/cm 2 per day for 1% mixing, and to 9.645 x 10 -5 g/cm 2 per day for 3% mixing. It was also found that the application of a latex paint reduced these leaching rates by about 10%. These results, along with mechanical strength tests (under radiation exposure, high temperature, long water immersion and freeze-thaw cycling) indicate that Syrian Portland cement is suited for the disposal of low-level radioactive waste.

Full Text Available Background: The aim of our study was to investigate the clinical and histopathological characteristics of cutaneous leishmaniasis (CL in the city of Sanliurfa in Turkey, where Syrian refugees also reside. Materials and Methods: At the Harran University Hospital outpatient clinics between 2012 and 2013, 54 CL cases, including 24 Syrian patients, underwent punch biopsy of the skin and/or a touch imprint. Patients in whom leishmania parasites were detected were included in the study. The clinical and histopathological data of the patients were obtained by a review of the patients′ medical records. All the slides of each patient were re-evaluated histopathologically. Results: Fifty-four cases (mean age; 17 ± 12 years, consisting of 32 males (59.3% and 22 females (40.7%, were examined. The most common site of involvement was the face (63%. The most common presentation was noduloulcerative lesions (57.4%. Histopathologically, the majority of the cases exhibited hyperkeratosis, follicular plugging of the epidermis, chronic inflammatory infiltration, leishmania amastigotes and non-caseating granulomatous inflammation in the dermis. Conclusion: CL presents with a wide spectrum of expression, both clinically and histologically, and may mimic other inflammatory and neoplastic diseases. The diagnosis of CL relies on the identification of leishmania amastigotes in either a direct smear of the lesion or in a tissue section.

The purpose of this study was to examine the economic and financial feasibility of a food irradiation project proposed by the Syrian Atomic Energy Commission. The prime purpose of the project was to irradiate two important agricultural products, namely, onion and potato. The irradiation process has the effect of reducing sprouting significantly. In Syria onions are usually stored in well ventilated warehouses at ambient temperature. Our investigation showed that sprouting started after 1.5 months of storage. It is estimated that the sprouting rate reaches 100% after five months of storage. This implies a waste factor of 50%. (author). 7 refs., 4 tabs

In Nigeria, the first Nuclear Reactor achieved critically on February 03, 2004 at about 11:35 GMT and has been commissioned or training and research. It is a Miniature Neutron Source Reactor (MNSR), code-named Nigeria Research Reactor-1 (NIRR-1). NIRR-1 has a tan-in-pool structural configuration and a nominal thermal power rating of 30 Kw. With a built-in clean old core excess reactivity of 3.77 mk determined during the on-site zero and critically experimental, the reactor can operate for a n.cm-2 .s-1 in the inner irradiation channels). Under these conditions, the reactor can operate with the same fuel loading for over ten years with a burn-up of <1%. A detailed description of operating characteristics for NIRR-1, measured during the on-site zero-power and criticality experiments has been given elsewhere. In order to extend its utilization to include absolute and ko-NAA methods, the neutron spectrum parameters in the irradiation channels: power and critically experiments has been given elsewhere. In order to extend it's the irradiation channels: thermal-to-epithermal flux ration, F; and epithermal flux shape factor, a in both the inner and outer irradiation channels must be determined experimentally. In this work, we have developed and experimental procedure for monitoring the neutron spectrum parameters in an inner irradiation channel based on irradiation and gamma-ray counting of detector foils via (n,y), (n,p) and (n,a) dosimetry reactions. Results obtained indicate that a thermal neutron flux of (5.14+-0.02) x 1011 n/c m2.s determined by foil activation method in the inner irradiation channel, B2, at a power level of 15.5 kw corresponds to the flux indicators on the control console and the micro-computer control system respectively. Other parameters of the neutron spectrum determined for inner irradiation channel B2, are: a -0.0502+0.003; 18.92+-0.14; F = 3.87=0.23. The method was validated through the comparison of our result with published neutron spectrum

Plasma Structure and Behavior of Miniature Ring-Cusp Discharges

Science.gov (United States)

Mao, Hann-Shin

Miniature ring-cusp ion thrusters provide a unique blend of high efficiencies and millinewton level thrust for future spacecraft. These thrusters are attractive as a primary propulsion for small satellites that require a high delta V, and as a secondary propulsion for larger spacecraft that require precision formation flying, disturbance rejection, or attitude control. To ensure desirable performance throughout the life of such missions, an advancement in the understanding of the plasma structure and behavior of miniature ring-cusp discharges is required. A research model was fabricated to provide a simplified experimental test bed for the analysis of the plasma discharge chamber of a miniature ion thruster. The plasma source allowed for spatially resolved measurements with a Langmuir probe along a meridian plane. Probe measurements yielded plasma density, electron temperature, and plasma potential data. The magnetic field strength was varied along with the discharge current to determine the plasma behavior under various conditions. The structure of the plasma properties were found to be independent of the discharge power under the proper scaling. It was concluded that weaker magnetic fields can improve the overall performance for ion thruster operation. To further analyze the experimental measurements, a framework was developed based on the magnetic field. A flux aligned coordinate system was developed to decouple the perpendicular and parallel plasma motion with respect to the magnetic field. This was done using the stream function and magnetic scalar potential. Magnetic formulae provided intuition on the field profiles dependence on magnet dimensions. The flux aligned coordinate system showed that the plasma was isopycnic along constant stream function values. This was used to develop an empirical relation suitable for estimating the spatial behavior and to determine the plasma volume and loss areas. The plasma geometry estimates were applied to a control volume

The number of human teeth that can be radiographically taken is limited. Moreover, at least two X-ray shots are required to get images of teeth from both sides of the mouth. In order to overcome the disadvantages of conventional dental radiography, a dental radiograph has been proposed in which an X-ray tube is inserted into the mouth while an X-ray detector is placed outside the mouth. The miniature X-ray tube is required small size to insert into the mouth. Recently, we have fabricated a miniature x-ray tube with the diameter of 7 mm using a carbon nanotube (CNT) field. But, commercialized miniature X-ray tube were adopted a thermionic type using tungsten filament. The X-ray tubes adopted thermionic emission has a disadvantage of increasing temperature of x-ray tube. So it need to cooling system to cool x-ray tube. On the other hands, X-ray tubes adopted CNT field emitters don't need cooling systems because electrons are emitted from CNT by applying high voltage without heating. We have developed the miniature x-ray tube that produce x-ray with uniform spatial distribution based on carbon nanotube field emitters. The fabricated miniature x-ray tube can be stably and reliably operated at 50kV without any vacuum pump. The developed miniature X-ray tube was applied for intraoral dental radiography that employs an intra-oral CNT-based miniature X-ray tube and extra-oral X-ray detectors. An X-ray image of many teeth was successfully obtained by a single X-ray shot using the intra-oral miniature X-ray tube system. Furthermore, images of both molar teeth of pig were simultaneously obtained by a single X-ray shot. These results show that the intraoral dental radiography, which employs an intraoral miniature X-ray tube and an extraoral X-ray detector, performs better than conventional dental radiography

2016-09-01

Full Text Available The availability of devices for cancer biomarker detection at early stages of the disease is one of the most critical issues in biomedicine. Towards this goal, to increase the assay sensitivity, device miniaturization strategies empowered by the employment of high affinity protein binders constitute a valuable approach. In this work we propose two different surface-based miniaturized platforms for biomarker detection in body fluids: the first platform is an atomic force microscopy (AFM-based nanoarray, where AFM is used to generate functional nanoscale areas and to detect biorecognition through careful topographic measurements; the second platform consists of a miniaturized electrochemical cell to detect biomarkers through electrochemical impedance spectroscopy (EIS analysis. Both devices rely on robust and highly-specific protein binders as aptamers, and were tested for thrombin detection. An active layer of DNA-aptamer conjugates was immobilized via DNA directed immobilization on complementary single-stranded DNA self-assembled monolayers confined on a nano/micro area of a gold surface. Results obtained with these devices were compared with the output of surface plasmon resonance (SPR assays used as reference. We succeeded in capturing antigens in concentrations as low as a few nM. We put forward ideas to push the sensitivity further to the pM range, assuring low biosample volume (μL range assay conditions.

2017-01-01

The push towards miniaturized electronics calls for the development of miniaturized energy-storage components that can enable sustained, autonomous operation of electronic devices for applications such as wearable gadgets and wireless sensor networks. Microsupercapacitors have been targeted as a viable route for this purpose, because, though storing less energy than microbatteries, they can be charged and discharged much more rapidly and have an almost unlimited lifetime. In this Review, we discuss the progress and the prospects of integrated miniaturized supercapacitors. In particular, we discuss their power performances and emphasize the need of a three-dimensional design to boost their energy-storage capacity. This is obtainable, for example, through self-supported nanostructured electrodes. We also critically evaluate the performance metrics currently used in the literature to characterize microsupercapacitors and offer general guidelines to benchmark performances towards prospective applications.

The Miniature Neutron Source Reactor (MNSR) in Syria has five inner irradiation sites in the annulus Beryllium reflectors to analyze the unknown samples using the Neutron Activation Analysis technique and to produce medium and short half life isotopes. The fast neutron flux spectrum has a special importance in the MNSR reactor physics where this spectrum is required to measure the fast neutron flux in the MNSR inner irradiation sites. Hence, calculation of the fast neutron flux spectrum in the MNSR inner irradiation site is conducted in this work using the WIMSD4 code. The energy range is divided in the WIMSD4 to 69 energy groups. The first six energy groups represent the fast neutron ranging from 0.5 to 10 MeV. To calculate the fast neutron flux spectrum in the MNSR inner irradiation site using the WIMSD4 code, the MNSR is modeled as a super unit cell. This cell consists of three regions which are: the homogenized core, annulus Beryllium, and water. The fast neutron spectrum is calculated also using the U 235 fission neutron spectrum approximation. The U 235 fission neutron spectrum agrees very good with the WIMSD4 results when neutron energy exceeds 1 MeV, but it fails when the neutron energy ranges from 0.5 to 1 MeV. The WIMSD4 code is used as well to calculate the microscopic fission cross sections for the U 238 using six energy groups where a unit cell of U 238 is used since the U 238 is usually used to measure the fast neutron flux in the reactor. The macroscopic fission cross sections for the U 238 are calculated first then the microscopic fission cross sections are calculated knowing the U 238 atomic density. (Author)

Umbarger, C.J.; Wolf, M.A.

1980-01-01

A miniaturized radiation chirper for use with a small battery supplying on the order of 5 volts is described. A poor quality CdTe crystal which is not necessarily suitable for high resolution gamma ray spectroscopy is incorporated with appropriate electronics so that the chirper emits an audible noise at a rate that is proportional to radiation exposure level. The chirper is intended to serve as a personnel radiation warning device that utilizes new and novel electronics with a novel detector, a CdTe crystal. The resultant device is much smaller and has much longer battery life than existing chirpers

A Typology of Secondary Stressors Among Refugees of Conflict in the Middle East: The Case of Syrian Refugees in Jordan.

As the years of displacement accumulate, the burden of secondary stressors (i.e., stressors not directly related to war) increase on the shoulders of millions of refugees, who do not have the option of either returning home due to war or having a sustainable livelihood in the host countries. This paper aims to shed light on the overlooked importance of secondary stressors among refugees of conflict in developing countries; it will do this by highlighting the experience of Syrian refugees in Jordan, and developing a typology of these stressors. We approached this issue using two levels of exploration. In study 1, we used participant observation and 15 in-depth interviews in Irbid, Jordan. Data were analysed qualitatively using thematic analysis to explore the different types of stressors. In study 2, a questionnaire survey among Syrian refugees in Jordan (n = 305) was used to collect data about a wide range of stressors. Responses were subjected to factor analysis to examine the extent to which the stressors could be organized into different factors. The thematic analysis suggested three different types of secondary stressors: financial (money related), environmental (exile structures and feelings created by it), and social (directly related to social relations). The factor analysis of the survey data produced a similar typology, where secondary stressors were found to be grouped into four main factors (financial, services, safety, and relations with out-groups). The final result is a typology of 33 secondary stressors organised in three main themes. Syrian refugees in Jordan suffer the most from financial stressors, due to loss of income and high living expenses. Environmental stressors arise from exile and are either circumstantial (e.g., services and legal requirements) or created by this environment (e.g., instability and lack of familiarity). Social stressors were observed among a considerable section of refugees, varying from stressors due to being targeted as

DEZP Company has used to collect product water, scale and sludge in artificial pits. Run-off channel had been created to allow water to run-off into the desert. A radioactive contamination by NORM in DEZP oil fields (JAFRA) has occurred and quite significant area of land has been affected. As a part of the remediation project the volume of contaminated soil with NORM according to the Syrian criteria for clean up and disposal has been determined. Surface and core soil samples were collected from the contaminated areas and analyzed for 226 Ra. The results have shown that contamination has reached a depth of more than one meter in the surface water pit. The estimated contaminated soil that needs disposal according to the Syrian criteria was calculated and found to be about 3161 m 3 . Most of the contaminated soil was found to be in the surface water pit. In addition, the contamination in the mud pit and the run-off channel was rather small and could be treated on site. However, the obtained results can be used for preparation of the remediation plan where size of the disposal pit and on site treatment is defined. The plan should be submitted to the Syrian Regulatory Office for review and approval to initiation of the remediation work (author)

The light microscope is traditionally an instrument of substantial size and expense. Its miniaturized integration would enable many new applications based on mass-producible, tiny microscopes. Key prospective usages include brain imaging in behaving animals towards relating cellular dynamics to animal behavior. Here we introduce a miniature (1.9 g) integrated fluorescence microscope made from mass-producible parts, including semiconductor light source and sensor. This device enables high-speed cellular-level imaging across ∼0.5 mm2 areas in active mice. This capability allowed concurrent tracking of Ca2+ spiking in >200 Purkinje neurons across nine cerebellar microzones. During mouse locomotion, individual microzones exhibited large-scale, synchronized Ca2+ spiking. This is a mesoscopic neural dynamic missed by prior techniques for studying the brain at other length scales. Overall, the integrated microscope is a potentially transformative technology that permits distribution to many animals and enables diverse usages, such as portable diagnostics or microscope arrays for large-scale screens.

Al-Hilal, M.; Al-Ali, A.; Jubeli, Y.

1997-02-01

Groundwater radon data were recorded once every two months from six monitoring sites of the Syrian rift valley during the year 1996. Radon samples were measured from deep artesian wells and from continuously-flowing springs that are distributed along this most active seismic zone in Syria. The available data were integrated with previously measured groundwater radon data from the same stations in order to estimate the range of normal radon fluctuations in the region. The estimation of such range may enable the separation between usual groundwater radon variations from other outliers which may indicate possible tectonic activities or earthquake hazards in the study area. Periodical radon measurements based on two months intervals and long distance between sampling stations does not enable us to trust with high level of confidence the connection between radon values and any possible earth dynamics. Therefore, shorter measuring time with closer monitoring sites are highly recommended to achieve the optimum advantage of such application. (Author). 8 Figs., 2 Tabs., 10 Refs

Shlewit, H.; Alibrahim, M.

2007-01-01

Syrian petroleum coke samples were characterized and submitted for salt-roasting treatment in electric furnace to evaluate the convenience of this procedure for the extraction of the vanadium, nickel and sulfur from coke. Both solution and solid residue remaining after salt roasting were separated by filtration and were analyzed for vanadium, nickel and sulfur. The solution was analyzed by UV-Visible spectroscopy for vanadium and nickel and gravimetrically for sulfur. The solid residue and the untreated samples of petroleum coke were analyzed by XRF spectrometry. Results showed that more than 90% of sulfur and 60% of vanadium could be extracted by salt roasting treatment. An alternative procedure has been suggested, in which, more than 80% of sulfur and small percentage of vanadium can be leached by 0.75 M of Na 2 CO 3 solution at 70-80 Co. Vanadium was selectively extracted by DEHPA/TBP from the loaded leached solution. The extraction procedure flowsheet was also suggested. (authors)

Scandinavia’s Daughters in the Syrian Civil War: What can we Learn from their Family Members’ Lived Experiences?

Directory of Open Access Journals (Sweden)

Andrea Aasgaard

2017-12-01

Full Text Available The phenomenon of Scandinavians joining Salafi-jihadi groups in the Syrian civil war is high on the political agendas of Scandinavian countries. To counter the phenomenon, authorities are increasingly focused on the inclusivity of families in efforts to counter violent extremism. However, research on the topic is limited. This article seeks to remedy this, by investigating the insights that can be gained from the lived experiences of relatives of three Scandinavian women who have joined Syrian Salafi-jihadi groups, primarily the Islamic State, based on ethnographic fieldwork. Through a narrative analysis of family members’ stories, this article critically discusses two different ways that family members’ lived experiences are used within the field of violent extremism. Firstly, media and researchers use the lived experiences of family members to explain why European Muslims join Salafi-Jihadi groups. Secondly, political initiatives increasingly emphasise that families should be involved in efforts to stop young men and women from becoming foreign fighters. This article employs these insights to discuss how the narratives of family members can be used to understand why people become foreign fighters, and to consider the role of the family in countering violent extremism efforts.

The Syrian refugee crisis in Lebanon required a fast and efficient comprehensive rescue strategy. Professionals working in emergency response were neither prepared to provide psychological first aid nor prepared to screen for mental health disorders in child refugees. This article examines the efficacy of a national training program in psychological first aid (PFA) to enhance the readiness of mental health field workers in the Syrian refugee response. Participant (N = 109) were recruited from Lebanese ministries and nongovernmental organizations. They received a 2.5-day training on PFA and on screening for mental health disorders in children. Their knowledge and perceived readiness were assessed before the training, immediately after the training, and 1 month after the training using 2 evaluation forms. Evaluation Form A was a multiple choice questionnaire composed of 20 questions and created on the basis of the content of the training, and Evaluation Form B was a Likert-type scale of 20 items created based on the core components of PFA. The data of 60 participants were analyzed. The results showed a significant increase in knowledge and readiness, specifically on the components related to the principles and techniques of PFA.

This study was carried out to develop a miniature magnetic fluid (MF) seal working in a liquid environment. The miniature MF seal is intended for use in a catheter blood pump. The requirements for the MF seal included a size of less than Ø4×4.5 mm, shaft diameter of 1 mm, sealing pressure of 200 mmHg, shaft speed of up to 40000 rpm, and life of one month. The miniature MF seal was composed of an NdFeB magnet (Ø4×Ø2×1) sandwiched between two pole pieces (Ø4×Ø1.1×0.5). A shield (Ø4×Ø1.2×1.5) was placed on the pole piece facing the liquid to minimize the influence of pump flow on the MF. The seal was installed on a Ø1 shaft. A seal was formed by injecting MF (Ms: 47.8 kA/m and η: 0.5 Pa·sec) into the gap between the pole pieces and the shaft. Total volume of the MF seal was 44 μL. A sealing pressure of 370 mmHg was obtained at motor speeds of 0-40,000 rpm. The seal remained perfect for 10 days in saline under the condition of a pump flow of 1.5 L/min (The test was terminated in accordance with plans). The seal remained intact after ethylene oxide sterilization during which the seal was exposed to high pressures. In conclusion, the newly developed MF seal will be useful for a catheter pump. - Highlights: • A miniature magnetic fluid seal working in a liquid environment was developed. • The seal can be installed on Ø1 mm shaft and can seal against 370 mmHg at 40000 rpm. • The magnetic fluid seal will be useful for a catheter blood pump.

The purpose of this article is to underline the miniaturized LC instrumental system and describe the evolution of commercially available systems by discussing their advantages and drawbacks. Nowadays, there are already many miniaturized LC systems available with a great variety of pump design, interface and detectors as well as efficient columns technologies and reduced connections devices. The solvent delivery systems are able to drive the mobile phase without flow splitters and promote gradient elution using either dual piston reciprocating or syringe-type pumps. The mass spectrometry as detection system is the most widely used detection system; among many alternative ionization sources direct-EI LC-MS is a promising alternative to APCI. In addition, capillary columns are now available showing many possibilities of stationary phases, inner diameters and hardware materials. This review provides a discussion about miniaturized LC demonstrating fundamentals and instrumentals' aspects of the commercially available miniaturized LC instrumental system mainly nano and micro LC formats. This review also covers the recent developments and trends in instrumentation, capillary and nano columns, and several applications of this very important and promising field.

The insecticide buprofezin was examined for its genotoxicity in cultured Syrian hamster embryo cells in order to better understand the mechanisms underlying the genotoxicity of the compound in mammalian cells. Exposure to buprofezin concentrations of 12.5-100 microM did not significantly affect the colony-forming ability of the cells, but did result in increased frequencies of morphologically transformed colonies. Treatment with buprofezin did not cause a detectable induction of DNA repair synthesis, an indicator of DNA damage, but significantly increased the frequency of micronuclei. Immunostaining of the cells with antikinetochore antibody (CREST antibody) showed that essentially all of the buprofezin-induced micronuclei were kinetochore-positive. The results suggest that morphological transformation of Syrian hamster embryo cells by buprofezin results from an interaction of the compound or a metabolite of it with the mitotic apparatus rather than from DNA damage.

2007-04-01

This paper describes recent progress conducted towards the development of a miniature fiber Bragg grating sensor interrogator (FBG-Transceiver TM) system based on multi-channel integrated optic sensor (InOSense TM) microchip technology. The hybrid InOSense TM microchip technology enables the integration of all of the functionalities, both passive and active, of conventional bench top FBG sensor interrogator systems, packaged in a miniaturized, low power operation, 2-cm x 5-cm package suitable for the long-term structural health monitoring in applications where size, weight, and power are critical for operation. The FBG-Transceiver system uses active optoelectronic components monolithically integrated to the InOSense TM microchip, a microprocessor controlled signal processing electronics board capable of processing the FBG sensors signals related to stress-strain and temperature as well as vibration and acoustics. The FBG-Transceiver TM system represents a new, reliable, highly robust technology that can be used to accurately monitor the status of an array of distributed fiber optic Bragg grating sensors installed in critical infrastructures. Its miniature package, low power operation, and state-of-the-art data communications architecture, all at a very affordable price makes it a very attractive solution for a large number of SHM/NDI applications in aerospace, naval and maritime industry, civil structures like bridges, buildings and dams, the oil and chemical industry, and for homeland security applications. The miniature, cost-efficient FBG-Transceiver TM system is poised to revolutionize the field of structural health monitoring and nondestructive inspection market.

This study was intended to report our recent experience of bladder injuries due to gunshots in the Syrian conflict and review the literature regarding diagnosis and treatment. Twenty-two cases with abdominal and inguinal firearm wounds and bladder ruptures sustained in the Syrian conflict were reported. Age, mechanism/location of damage, associated injuries, Revised Trauma Score (RTS), Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), and complications were analyzed. The severity of the bladder injuries was classified according to the American Association for the Surgery of Trauma Organ Injury Scaling (AAST-OIS grade ?II database).The type of the bladder rupture was defined according to the classification System for Bladder Injury Based on Findings at CT Cystography. The mean age was 26 years (range, 18-36). The mean ISS was 22 (10-57), mean TRISS was 0.64 (0.004-0.95), and mean RTS was 6.97 (3.30-7.84). In the mortality group, the mean ISS, TRISS, and RTS were 48 (36-57), 0.016 (0.004-0.090), and 4.10 (3.30-4.92), respectively; whereas, the mean ISS, TRISS, and RTS were found as 21 (10-26), 0.64 (0.49-0.95), and 7.24 (5.65-7.84), respectively in the survival group (P=0.06). CT-cystography showed seventeen type 2, three type 4, and two type 5 bladder injuries. According to AAST-OIS, there were nine grade IV, six grade III, five grade II, and two grade V injuries. In war settings, when injuries are often severe and multiple surgical exploration and closure are mandatory, mortality risk is associated with high ISS and low TRISS and RTS values.

The current conflict in Syria continues to displace thousands to neighboring countries, including Lebanon. Information is needed to provide adequate health and related services particularly to women in this displaced population. We conducted a needs assessment in Lebanon (June-August 2012), administering a cross-sectional survey in six health clinics. Information was collected on reproductive and general health status, conflict violence, stress, and help-seeking behaviors of displaced Syrian women. Bivariate and multivariate analyses were conducted to examine associations between exposure to conflict violence, stress, and reproductive health outcomes. We interviewed 452 Syrian refugee women ages 18-45 who had been in Lebanon for an average of 5.1 (± 3.7) months. Reported gynecologic conditions were common, including: menstrual irregularity, 53.5%; severe pelvic pain, 51.6%; and reproductive tract infections, 53.3%. Among the pregnancy subset (n = 74), 39.5% of currently pregnant women experienced complications and 36.8% of those who completed pregnancies experienced delivery/abortion complications. Adverse birth outcomes included: low birthweight, 10.5%; preterm delivery, 26.5%; and infant mortality, 2.9%. Of women who experienced conflict-related violence (30.8%) and non-partner sexual violence (3.1%), the majority did not seek medical care (64.6%). Conflict violence and stress score was significantly associated with reported gynecologic conditions, and stress score was found to mediate the relationship between exposure to conflict violence and self-rated health. This study contributes to the understanding of experience of conflict violence among women, stress, and reproductive health needs. Findings demonstrate the need for better targeting of reproductive health services in refugee settings, as well as referral to psychosocial services for survivors of violence.

Variants in the serine protease inhibitor Kazal type 1 (SPINK1) gene have been associated with pancreatitis in Miniature Schnauzers. Replication of the association in an independent population is necessary to determine if genetic screening for SPINK1 variants should be considered in clinical practice. An association between the SPINK1 exonic variant c.74A > C and pancreatitis exists in Miniature Schnauzers. In addition, the variant is absent or rare in Standard Schnauzers, a related breed that is not reported to have an increased risk for pancreatitis. Case-control study. Seventeen Miniature Schnauzers with pancreatitis (cases), 60 mature Miniature Schnauzers with no substantial history of gastrointestinal signs in their lifetime (controls), and 31 Standard Schnauzers of unknown pancreatitis status. A PCR-RFLP assay was used to genotype dogs for the c.74A > C SPINK1 variant. Allele and genotype frequencies were reported for Schnauzers and compared between case and control Miniature Schnauzers. The c.74A > C variant was the major allele in both Schnauzer breeds with a frequency of 0.77 in Miniatures and 0.55 in Standards. The allele and genotype frequencies were similar between Miniature Schnauzers with and without a history of pancreatitis and did not impart an increased risk for pancreatitis. Genotyping a larger population of the Miniature Schnauzer breed than a previous study, along with a Standard Schnauzer cohort, demonstrated that the SPINK1 c.74A > C variant is a common polymorphism in the Schnauzer lineage. Furthermore, we were unable to confirm a relationship between the variant and clinically detectable pancreatitis in Miniature Schnauzers.

2016-05-01

We report on a miniature fiber-optic multiphoton microscopy (MPM) system based on a frequency-doubled femtosecond Er-doped fiber laser. The femtosecond pulses from the laser source are delivered to the miniature fiber-optic probe at 1.58 µm wavelength, where a standard single mode fiber is used for delivery without the need of free-space dispersion compensation components. The beam is frequency-doubled inside the probe by a periodically poled MgO:LiNbO3 crystal. Frequency-doubled pulses at 786 nm with a maximum power of 80 mW and a pulsewidth of 150 fs are obtained and applied to excite intrinsic signals from tissues. A MEMS scanner, a miniature objective, and a multimode collection fiber are further used to make the probe compact. The miniature fiber-optic MPM system is highly portable and robust. Ex vivo multiphoton imaging of mammalian skins demonstrates the capability of the system in imaging biological tissues. The results show that the miniature fiber-optic MPM system using frequency-doubled femtosecond fiber laser can potentially bring the MPM imaging for clinical applications.

Full Text Available Background: The most common mental health problems among refugees are depression and posttraumatic stress disorder (PTSD. Eye movement desensitization and reprocessing (EMDR is an effective treatment for PTSD. However, no previous randomized controlled trial (RCT has been published on treating PTSD symptoms in a refugee camp population. Objective: Examining the effect of EMDR to reduce the PTSD and depression symptoms compared to a wait-list condition among Syrian refugees. Method: Twenty-nine adult participants with PTSD symptoms were randomly allocated to either EMDR sessions (n=15 or wait-list control (n=14. The main outcome measures were Impact of Event Scale-Revised (IES-R and Beck Depression Inventory (BDI-II at posttreatment and 4-week follow-up. Results: Analysis of covariance showed that the EMDR group had significantly lower trauma scores at posttreatment as compared with the wait-list group (d=1.78, 95% CI: 0.92–2.64. The EMDR group also had a lower depression score after treatment as compared with the wait-list group (d=1.14, 95% CI: 0.35–1.92. Conclusion: The pilot RCT indicated that EMDR may be effective in reducing PTSD and depression symptoms among Syrian refugees located in a camp. Larger RCTs to verify the (cost- effectiveness of EMDR in similar populations are needed.

There is a clear need for miniaturized, lightweight, accurate and inexpensive star tracker for spacecraft with large anglar rate. To face these new constraints, the Beijing Institute of Space Long March Vehicle has designed, built and flown a low cost miniaturized star tracker that provides autonomous ("Lost in Space") inertial attitude determination, 2 Hz 3-axis star tracking, and digital imaging with embedded compression. Detector with high sensitivity is adopted to meet the dynamic and miniature requirement. A Sun and Moon avoiding method based on the calculation of Sun and Moon's vector by astronomical theory is proposed. The produced prototype weight 0.84kg, and can be used for a spacecraft with 6°/s anglar rate. The average angle measure error is less than 43 arc second. The ground verification and application of the star tracker during the pick-up flight test showed that the capability of the product meet the requirement.

Assessment of the gas dynamic trap mirror facility as intense neutron source for fusion material test irradiations

International Nuclear Information System (INIS)

Fischer, U.; Moeslang, A.; Ivanov, A.A.

2000-01-01

The gas dynamic trap (GDT) mirror machine has been proposed by the Budker Institute of nuclear physics, Novosibirsk, as a volumetric neutron source for fusion material test irradiations. On the basis of the GDT plasma confinement concept, 14 MeV neutrons are generated at high production rates in the two end sections of the axially symmetrical central mirror cell, serving as suitable irradiation test regions. In this paper, we present an assessment of the GDT as intense neutron source for fusion material test irradiations. This includes comparisons to irradiation conditions in fusion reactor systems (ITER, Demo) and the International Fusion Material Irradiation Facility (IFMIF), as well as a conceptual design for a helium-cooled tubular test assembly elaborated for the largest of the two test zones taking proper account of neutronics, thermal-hydraulic and mechanical aspects. This tubular test assembly incorporates ten rigs of about 200 cm length used for inserting instrumented test capsules with miniaturized specimens taking advantage of the 'small specimen test technology'. The proposed design allows individual temperatures in each of the rigs, and active heating systems inside the capsules ensures specimen temperature stability even during beam-off periods. The major concern is about the maximum achievable dpa accumulation of less than 15 dpa per full power year on the basis of the present design parameters of the GDT neutron source. A design upgrading is proposed to allow for higher neutron wall loadings in the material test regions

Full Text Available This paper reports a miniaturized piezoelectric accelerometer suitable for a small haptic actuator array. The accelerometer is made with zinc oxide (ZnO nanowire (NW grown on a copper wafer by a hydrothermal process. The size of the accelerometer is 1.5 × 1.5 mm2, thus fitting the 1.8 × 1.8 mm2 haptic actuator array cell. The detailed fabrication process of the miniaturized accelerometer is illustrated. Performance evaluation of the fabricated accelerometer is conducted by comparing it with a commercial piezoelectric accelerometer. The output current of the fabricated accelerometer increases linearly with the acceleration. The miniaturized ZnO NW accelerometer is feasible for acceleration measurement of small and lightweight devices.

Full Text Available Human adenoviruses have been studied extensively in cell culture and have been a model for studies in molecular, cellular, and medical biology. However, much less is known about adenovirus replication and pathogenesis in vivo in a permissive host because of the lack of an adequate animal model. Presently, the most frequently used permissive immunocompetent animal model for human adenovirus infection is the Syrian hamster. Species C human adenoviruses replicate in these animals and cause pathology that is similar to that seen with humans. Here, we report findings with a new Syrian hamster strain in which the STAT2 gene was functionally knocked out by site-specific gene targeting. Adenovirus-infected STAT2 knockout hamsters demonstrated an accentuated pathology compared to the wild-type control animals, and the virus load in the organs of STAT2 knockout animals was 100- to 1000-fold higher than that in wild-type hamsters. Notably, the adaptive immune response to adenovirus is not adversely affected in STAT2 knockout hamsters, and surviving hamsters cleared the infection by 7 to 10 days post challenge. We show that the Type I interferon pathway is disrupted in these hamsters, revealing the critical role of interferon-stimulated genes in controlling adenovirus infection. This is the first study to report findings with a genetically modified Syrian hamster infected with a virus. Further, this is the first study to show that the Type I interferon pathway plays a role in inhibiting human adenovirus replication in a permissive animal model. Besides providing an insight into adenovirus infection in humans, our results are also interesting from the perspective of the animal model: STAT2 knockout Syrian hamster may also be an important animal model for studying other viral infections, including Ebola-, hanta-, and dengue viruses, where Type I interferon-mediated innate immunity prevents wild type hamsters from being effectively infected to be used as
