    This true-color image over Morocco was acquired on April 23, 2000, by NASA's Moderate-resolution Imaging Spectroradiometer, or MODIS, flying aboard the Terra spacecraft. The image was produced using a combination of the sensor's 250-m and 500-m resolution bands. Notice the exquisite detail in the colors and textures of the variety of land surface features in northwestern Africa. The heavily-vegetated (green pixels) peninsula in the top center of the image is the southern shore of the Strait of Gibralter--the passage between the Atlantic Ocean and the Mediterranean Sea. Notice the patchy formation of low-level cumulus clouds (white pixels) over this region, suggesting a moister climate that contributes to better plant growth. On the tip of this peninsula is the coastal city of Tangier. Moving west along the coastline, the city of Casablanca lies about 200 miles (330 km) southwest of Tangier, and about 50 miles south of Rabat, the capital city. Both Casablanca and Rabat are visible as small grey clusters of pixels. About 200 miles due south of Casablanca, the Atlas Mountains (brownish pixels) are running in a northeasterly direction toward Algeria, Morocco's eastern neighbor. Toward the bottom right side of the image is a portion of the northwestern edge of the Sahara Desert. The most yellow pixels toward the southeast corner of the image is the region in the Sahara known as the Great Western Erg, in Algeria.

    One of the largest miscible gas injection projects in the world is in its 12th year in the Intisar ''D'' field in the Socialist People's Libyan Arab Jamahiriya. As of March 31, 1981, cumulative oil production totaled 890 MMbbl (141.4 X 10/sup 6/ m/sup 3/) of oil, or 56% recovery of the estimated stock-tank original oil in place (OOIP). This past performance and recent simulation studies indicate a final recovery efficiency on the order of 70%.

  18. Groundwater vulnerability mapping of Qatar aquifers

    NASA Astrophysics Data System (ADS)

    Baalousha, Husam Musa

    2016-12-01

    Qatar is one of the most arid countries in the world with limited water resources. With little rainfall and no surface water, groundwater is the only natural source of fresh water in the country. Whilst the country relies mainly on desalination of seawater to secure water supply, groundwater has extensively been used for irrigation over the last three decades, which caused adverse environmental impact. Vulnerability assessment is a widely used tool for groundwater protection and land-use management. Aquifers in Qatar are carbonate with lots of fractures, depressions and cavities. Karst aquifers are generally more vulnerable to contamination than other aquifers as any anthropogenic-sourced contaminant, especially above a highly fractured zone, can infiltrate quickly into the aquifer and spread over a wide area. The vulnerability assessment method presented in this study is based on two approaches: DRASTIC and EPIK, within the framework of Geographical Information System (GIS). Results of this study show that DRASTIC vulnerability method suits Qatar hydrogeological settings more than EPIK. The produced vulnerability map using DRASTIC shows coastal and karst areas have the highest vulnerability class. The southern part of the country is located in the low vulnerability class due to occurrence of shale formation within aquifer media, which averts downward movement of contaminants.

  20. Qatargas exporting LNG from Qatar`s new Ras Laffan Port

    SciTech Connect

    1997-02-24

    When the 135,000 cu m LNG carrier Al Zubarah departed Ras Laffan Port in December, Qatar entered a new era of commerce that will both boost the emirate`s economic development and influence energy trade around the world. The event capped more than a decade of planning, design, and construction of Ras Laffan Port--the world`s newest and largest LNG exporting facility. During the 1980s, the focus in Qatar was on exploration and development of North field, which holds the world`s largest reserves of nonassociated natural gas. In the 1990s, efforts concentrated on establishing a direct production and export link between North field, the new multi-billion-dollar Qatar Liquefied Gas Co. (Qatargas) gas liquefaction plant at Ras Laffan, and LNG export facilities at the 8.5 sq km Ras Laffan Port. Markets of the Far East will be first to be served by LNG from Ras Laffan Port. Two 25-year LNG supply contracts have been signed with buyers in Japan and South Korea, and negotiations are under way with potential customers from China, Taiwan, and Thailand. The paper describes the port, its operations, and export projects.

    2014-01-01

    Abstract We have updated the list of the lizard species present in Qatar and produced the first distribution maps based on two field surveys in 2012 and 2013. We used the QND95/Qatar National Grid with a grid of 10 × 10 km squares for mapping. Our results show the occurrence of 21 lizard species in Qatar, from the 15 species indicated in the last biodiversity report conducted in 2004. The most abundant family found in Qatar is Gekkonidae with nine species (Bunopus tuberculatus, Cyrtopodion scabrum, Hemidactylus robustus, H. flaviviridis, H. persicus, Stenodactylus arabicus, S. slevini, S. doriae, Pseudoceramodactylus khobarensis), followed by Lacertidae with four species (Acanthodactylus schmidti, A. opheodurus, Mesalina brevirostris, M. adramitana), Agamidae with three species (Trapelus flavimaculatus, Uromastyx aegyptia, Phrynocephalus arabicus), Scincidae with two species (Scincus mitranus, Trachylepis septemtaeniata), and Varanidae (Varanus griseus), Sphaerodactylidae (Pristurus rupestris) and Trogonophiidae (Diplometopon zarudnyi) with one species each. The species richness fluctuated largely across Qatar between one and eleven species per grid square. We believe that the lizard fauna records in Qatar are still incomplete and that additional studies are required. However, our study here fills a gap concerning lizard biodiversity knowledge in the Gulf Region. PMID:24493961

    2016-04-30

    Qatar's once extensive coral communities have undergone considerable change in recent decades. We quantitatively surveyed three coral assemblages in Qatar to assess current status, and compared these against 14 sites in Bahrain and the United Arab Emirates to evaluate Qatar in a larger biogeographic context. Umm Al-Arshan had the highest species richness of 17 sites examined in the southern Arabian Gulf, as well as the highest coral cover and the only Acropora observed on sites in Qatar. Coral cover and richness were more modest at Fuwayrit and Al-Ashat, reflecting greater impacts from earlier stress events. Two distinct communities were identified across the southern Gulf, with Umm Al-Arshan clustering with high-cover, mixed merulinid/poritid assemblages that were less impacted by earlier bleaching and long-term stress, while Fuwayrit and Al-Ashat grouped with a lower-cover, stress-tolerant community characteristic of more extreme environments in the southern Gulf. We recommend implementation of a nation-wide baseline assessment of coral communities to guide development of an MPA network and long-term coral monitoring program for Qatar.

  4. Hydrocarbon potential of Morocco

    SciTech Connect

    Achnin, H.; Nairn, A.E.M.

    1988-08-01

    Morocco lies at the junction of the African and Eurasian plates and carries a record of their movements since the end of the Precambrian. Four structural regions with basins and troughs can be identified: Saharan (Tarfaya-Ayoun and Tindouf basins); Anti-Atlas (Souss and Ouarzazate troughs and Boudnib basin); the Essaouria, Doukkala, Tadla, Missour, High Plateau, and Guercif basins; and Meseta and Rif (Rharb and Pre-Rif basins). The targets in the Tindouf basin are Paleozoic, Cambrian, Ordovician (clastics), Devonian (limestones), and Carboniferous reservoirs sourced primarily by Silurian shales. In the remaining basins, excluding the Rharb, the reservoirs are Triassic detritals, limestones at the base of the Lias and Dogger, Malm detritals, and sandy horizons in the Cretaceous. In addition to the Silurian, potential source rocks include the Carboniferous and Permo-Carboniferous shales and clays; Jurassic shales, marls, and carbonates; and Cretaceous clays. In the Rharb basin, the objectives are sand lenses within the Miocene marls. The maturation level of the organic matter generally corresponds to oil and gas. The traps are stratigraphic (lenses and reefs) and structural (horsts and folds). The seals in the pre-Jurassic rocks are shales and evaporites; in the younger rocks, shales and marl. Hydrocarbon accumulations have been found in Paleozoic, Triassic, Liassic, Malm, and Miocene rocks.

    2015-10-01

    Few estimates of fungal disease frequency have been attempted in the Middle East. We have estimated the burden of fungal infections in Qatar. The aim of the study was to compute and determine the burden of serious fungal infections, in an attempt to estimate fungal disease frequency, which has not previously been attempted in this country. Disease statistics were collected from the Microbiology laboratory database and from 2011 WHO statistics. The data are expressed per 100,000 populations. The reported cases of candidaemia rose to 288 with an estimated rate of 15.4/100,000. A real increase in the burden of candidaemia was found over that previously reported (12.9/100,000) for the years 2004-2009. Candida peritonitis was estimated in 8.02 cases/100,000 population. Recurrent (≥4 year(-1) ) vaginal infections affect at least 32,782 women with a rate of 3506/100,000 inhabitants. Severe asthma with fungal sensitisation affected 1486 people, allergic bronchopulmonary aspergillosis 1126 people and chronic pulmonary aspergillosis 176 people. Rhinosinusitis, mucormycosis and Fusarium infection occurred at rates of 2.31, 1.23, 1.86 cases/100,000 respectively. The estimated rate of invasive aspergillosis was very low (0.6/100,000). Low rates of Cryptococcus meningitis and Pneumocystis pneumonia are attributable to low HIV infection rates. In conclusion, fungal infections are increasingly reported, especially candidaemia. Surveillance and guidelines are needed to optimise care and management of common fungal infections. In addition, a fungal registry system needs development for surveillance.

  7. Impact of noncommunicable diseases in the State of Qatar

    PubMed Central

    Al-Kaabi, Salma Khalaf; Atherton, Andrew

    2015-01-01

    This study, commissioned by the Supreme Council of Health in the State of Qatar, focuses on the main noncommunicable diseases (NCDs) globally and regionally, in order to gauge their potential impact on Qatar. The research shows that the Gulf Cooperation Council is projected to be affected dramatically by NCDs in the coming years. The top five NCDs that will affect Qatar in terms of economic burden and disability-adjusted life years are cardiovascular diseases, mental health and behavioral disorders, cancer, respiratory diseases, and diabetes. Whilst these diseases have diverse effects on patients, their causes can be traced to “… common lifestyle-related, or behavioral, risk factors such as tobacco use, a diet heavy in fat, and physical inactivity”. The total direct and indirect costs to the Gulf Cooperation Council calculated for the above five NCDs were $36.2 billion in 2013, which equates to 150% of the officially recorded annual health care expenditure. If this trajectory is maintained, spending per head of population in Qatar will reach $2,778 by 2022. These figures demonstrate not only the potential financial impact of the main NCDs, but also give an idea of how the current health system is working to address them. PMID:26170702

  12. Joining the nursing profession in Qatar: motives and perceptions.

    PubMed

    Okasha, M S; Ziady, H H

    2001-11-01

    We aimed to identify why female students in Qatar decide to become nurses and how the students perceived the community attitude towards nursing. A self-administered anonymous questionnaire was distributed to all (57) female students of the four academic classes of the Nursing Unit, University of Qatar for the academic year 1999-2000. The two commonest reasons for joining the nursing profession were an interest in medical services and the humanitarian nature of nursing. There were 33 (57.89%) students who considered there was a negative community attitude towards nursing mainly due to the presence of male patients and colleagues and the working hours. A mass media campaign and govemmental support were two strategies suggested to change this.

  13. Arranging marriage; negotiating risk: genetics and society in Qatar.

    Kilshaw, Susie; Al Raisi, Tasneem; Alshaban, Fouad

    2015-01-01

    This paper considers how the globalized discourse of genetic risk in cousin marriage is shaped, informed and taken up in local moral worlds within the context of Qatar. This paper investigates the way Qataris are negotiating the discourse on genetics and risk. It is based on data from ongoing ethnographic research in Qatar and contributes to anthropological knowledge about this understudied country. Participants were ambivalent about genetic risks and often pointed to other theories of causation in relation to illness and disability. The discourse on genetic risk associated with marrying in the family was familiar, but for some participants the benefits of close marriage outweighed potential risks. Furthermore, the introduction of mandatory pre-marital screening gave participants confidence that risks were monitored and minimized.

  18. Identification of wind fields for wave modeling near Qatar

    NASA Astrophysics Data System (ADS)

    Nayak, Sashikant; Balan Sobhana, Sandeepan; Panchang, Vijay

    2016-04-01

    Due to the development of coastal and offshore infrastructure in and around the Arabian Gulf, a large semi-enclosed sea, knowledge of met-ocean factors like prevailing wind systems, wind generated waves, and currents etc. are of great importance. Primarily it is important to identify the wind fields that are used as forcing functions for wave and circulation models for hindcasting and forecasting purposes. The present study investigates the effects of using two sources of wind-fields on the modeling of wind-waves in the Arabian Gulf, in particular near the coastal regions of Qatar. Two wind sources are considered here, those obtained from ECMWF and those generated by us using the WRF model. The wave model SWAN was first forced with the 6 hourly ERA Interim daily winds (from ECMWF) having spatial resolution of 0.125°. For the second option, wind fields were generated by us using the mesoscale wind model (WRF) with a high spatial resolution (0.1°) at every 30 minute intervals. The simulations were carried out for a period of two months (7th October-7th December, 2015) during which measurements were available from two moored buoys (deployed and operated by the Qatar Meteorological Department), one in the north of Qatar ("Qatar North", in water depth of 58.7 m) and other in the south ("Shiraouh Island", in water depth of 16.64 m). This period included a high-sea event on 11-12th of October, recorded by the two buoys where the significant wave heights (Hs) reached as high as 2.9 m (i.e. max wave height H ~ 5.22 m) and 1.9 (max wave height H ~ 3.4 m) respectively. Model results were compared with the data for this period. The scatter index (SI) of the Hs simulated using the WRF wind fields and the observed Hs was found to be about 30% and 32% for the two buoys (total period). The observed Hs were generally reproduced but there was consistent underestimation. (Maximum 27% for the high-sea event). For the Hs obtained with ERA interim wind fields, the underestimation was

    Qatar׳s farm workers provide a unique population for exposure study: they are young, healthy males. This study combined trace element profiles in urine and toenail with survey information from 239 farm workers to assess the extent to which the biomarkers provide complementary exposure information. Urinary Mo levels (average=114 µg/L) were elevated; average urinary values (µg/L) for all other elements were: V (1.02), Cr (0.55), Mn (2.15), Fe (34.1), Co (0.47), Ni (2.95), Cu (15.0), As (47.8), Se (25.7), Cd (1.09), Ba (22.5), Pb (2.50) and U (0.15). Average toenail concentrations (mg/kg) were: Mn (2.48), Cu (4.43), As (0.26), Se (0.58), Mo (0.07), Cd (0.03), Ba (1.00), Pb (0.51) and U (0.02). No significant association was found between corresponding elements in urine and toenails. Elemental profiles suggest groundwater (with the exception of Mo) and soil-dust-crop exposure pathways cannot account for elemental variations. The main factors moderating trace element contents are related to depuration processes involving participants׳ trace element body burden prior to work in Qatar, and interactions of trace element metabolic cycles which over-ride the exposure footprint. Toenail and urine need to be carefully validated before reliable use as biomarkers of exposure in general populations for most elements in the study.

  20. Anti-Atlas Mountains, Morocco

    NASA Technical Reports Server (NTRS)

    2002-01-01

    The Anti-Atlas Mountains of northern Africa and the nearby Atlas mountains were created by the prolonged collision of the African and Eurasian tectonic plates, beginning about 80 million years ago. Massive sandstone and limestone layers have been crumpled and uplifted more than 4,000 meters in the High Atlas and to lower elevations in the Anti-Atlas. Between more continuous major fold structures, such as the Jbel Ouarkziz in the southwestern Anti-Atlas, tighter secondary folds (arrow) have developed. Earlier, the supercontinent of Pangea rifted apart to form precursors to the Mediterranean and the Atlantic Ocean (Beauchamp and others, 1996). In those seas sands, clays, limey sediments, and evaporite layers (gypsum, rock salt) were deposited. Later, during the mountain-building plate collision, the gypsum layers flowed under the pressure and provided a slippery surface on which overlying rigid rocks could glide (Burkhard, 2001). The broad, open style of folds seen in this view is common where evaporites are involved in the deformation. Other examples can be found in the Southern Zagros of Iran and the Sierra Madre Oriental of Mexico.

    The objective of this study was to find out the perceptions of age and aging among women in Qatar. Respondents consisted of 250 women aged between 20 and 70 years, selected from those attending the health centers in Doha city, the capital of Qatar. They were interviewed using a pretested validated questionnaire, and data were collected through direct face-to-face interviews using the incidental sampling method. It was found that physical appearance and mental alertness were the most important criteria for defining aging in men and women. A statistically significant association was found between age of respondents and physical criteria for aging such as hair color (p < .000) in women and body image in men (p < .0298). As for aging characteristics, decreasing hearing ability (p < .000), performance as before (p < .004), more irritability (p < .0227), ability to travel alone (p < .0429), needs check up (p < .001), and needs a geriatric home (p < .001) were statistically associated with age of women studied. Both positive (socializing factors, independence, housework, retirement, and geriatric care) and negative stereotyping (care for self, learning capabilities, irritability, and worries) with regard to aging were evident among the Qatari women. In general, Qatari women had several positive attitudes toward aging. Such attitudes could be utilized in any health promotion for elderly people.

    The objective of this study was to analyze long-term temperature-related phenomena in the eastern portion of the Middle East, focusing on the coastal region of Qatar. Extreme temperature indices were examined, which were defined by the Expert Team on Climate Change Detection and Indices, for Doha, Qatar; these indices were then compared with those from neighboring countries. The trends were calculated for a 30-year period (1983-2012), using hourly data obtained from the National Climatic Data Center. The results showed spatially consistent warming trends throughout the region. For Doha, 11 of the 12 indices studied showed significant warming trends. In particular, the warming trends were represented by an increase in the number of warm days and nights and a decrease in the number of cool nights and days. The high-temperature extremes during the night have risen at more than twice the rate of their corresponding daytime extremes. The intensity and frequency of hot days have increased, and the minimum temperature indices exhibited a higher rate of warming. The climatic changes in Doha are consistent with the region-wide heat-up in recent decades across the Middle East. However, the rapid economic expansion, increase of population since the 1990s, and urban effects in the region are thought to have intensified the rapidly warming climate pattern observed in Doha since the turn of the century.

    The prevalence of use of complementary and alternative medicine (CAM) is widespread and is growing worldwide. This cross-sectional study in Qatar examined the use of CAM and its correlates among Arab women in their midlife years. Women aged 40–60 years (n = 814) were recruited at primary health-care centres in Qatar and completed a specially designed, pre-tested questionnaire. Overall, 38.2% of midlife women in Qatar had used CAM in the previous 12 months. Nutritional remedies and herbal remedies were the most commonly used CAM therapies, followed by physical methods. Qatari nationality and higher level of education were independently associated with CAM use. Menopause transition status was not independently associated with use of CAM. The prevalence of CAM use by women in Qatar was high, consistent with other reports worldwide. It is essential to educate and inform patients and health-care providers about the benefits and limitations associated with CAM. PMID:25343468

    Fluoridation of drinking water has been recognized as one of the most effective ways of achieving community-wide exposure to the caries prevention effects of fluoride (F). A vast majority of people in Qatar use bottled water for drinking. Use of bottled water without knowing the F level may expose children to dental caries risk if the F level is lower than optimal or to dental fluorosis if the F level is too high. The aim of this study was to determine the F concentration of bottled water available in Qatar. A total of 32 brands of bottled water were evaluated. The F concentrations displayed on the labels were recorded. The F ion-selective electrode method was used to measure the F concentration in water samples, and three measurements were taken for every sample to ensure reproducibility. The p value was set at 0.05. The F concentration ranged from 0.06 to 3.0 ppm with a mean value of 0.8 ppm (±0.88). The F levels were provided by the manufacturers on the labels of 60 % of the samples, but this was significantly lower than the measured F levels (p < 0.0001). Moreover, bottled water that was produced in Saudi Arabia had significantly higher levels of F when compared to those produced in other countries (p < 0.05). There was a wide variation in the F levels in the different brands of bottled water. Furthermore, there was a significant disparity between the F levels which were measured and those that were provided on the labels.

    The European Commission (EC) supports programs using radio to inform and educate about HIV and AIDS in developing countries, particularly with regard to illiterate or rural populations. In 1992, in Comoros (where 80% of adults and 65% of persons aged 15-25 listen to radio and there is no national television and only one printed medium--a French magazine), as part of a National AIDS Programme initiative aimed at mobilizing youth and women leaders, two journalists of the national radio channel produced an EC-supported series of 20 radio programs that were broadcast twice weekly every other week as part of the popular program "Sante" (Health). A series of 11 programs were broadcast in 1994-95 by Radio Comoros and by two private stations that were popular with youth. Surveys showed the following: 1) the popular shows were the main source of information on HIV/AIDS and were particularly successful in rural communities when broadcast in the local language; 2) the majority of villagers wanted this and other health information to continue; and 3) public information regarding sexuality was accepted by a large majority. The radio series caused Islamic religious leaders to discuss HIV prevention and condoms. An EC-supported project in Morocco occurred in 1993. The 3-month national information campaign about HIV/AIDS covered myths and rumors, infection risks, prevention measures, the disease and women and youth, the epidemic's socioeconomic impact, the role of nongovernmental organizations (NGOs), and the role of the media. A 1-hour program in Arabic was broadcast twice a week for 24 weeks, 12 30-minute programs were broadcast in three Berber dialects, and several short spots were aired daily. The program format included presentations and discussions by health staff, psychologists, sociologists, and NGO staff; listener participation was allowed. 1000 men and 700 women were surveyed using a questionnaire. Roadside interviews were conducted in some cities. These showed that the

    Qatar's economy is based on oil and gas industry, which are mostly located in coastal regions. Therefore, better understanding of coastal weather, characteristics of surface layer and turbulence exchange processes is much needed. However, the turbulent atmospheric layer study in this region is severely limited. To support the broader aim and study long term precise wind information, a micro-meteorological field campaign has been carried out in a coastal location of north Qatar. The site is based on a 9 m tower, installed at Al Ghariya in the northern coast of Qatar, equipped with three sonic anemometers, temperature-humidity sensor, radiometer and a weather station. This study shows results based on the period August 2015 to July 2016. Various surface layer characteristics and modellings coefficients based on Monin Obukhov similarity theory is studied for the year and seasonal change is noted. Along with the seasonal variabilities of different weather parameters also observed. We hope this long term field observational study will be very much helpful for research community especially for modelers. In addition, two beach and shoreline monitoring cameras installed at the site could give first time information on waves and shoreline changes, and wind-wave interaction in Qatar.

    A structured research programme is one of the main pillars of a trauma care system. Despite the high rate of injury-related mortalities, especially road traffic accidents, in Qatar, little consideration has been given to research in trauma. This review aimed to analyse research publications on the subject of trauma published from Qatar and to discuss the progress of clinical research in Qatar and the Gulf Cooperation Council countries with special emphasis on trauma research. A literature search using PubMed and Google Scholar search engines located 757 English-language articles within the fields of internal medicine, surgery and trauma originating from Qatar between the years 1993 and 2013. A steep increase in the number of trauma publications since 2010 could be linked to the setting up of a trauma research centre in Qatar in 2011. We believe that establishing a research unit has made a major impact on research productivity, which ultimately benefits health care.

    Microplastics are firmly recognized as a ubiquitous and growing threat to marine biota and their associated marine habitats worldwide. The evidence of the prevalence of microplastics was documented for the first time in the marine waters of Qatar's Exclusive Economic Zone (EEZ). An optimized and validated protocol was developed for the extraction of microplastics from plankton-rich seawater samples without loss of microplastic debris present and characterized using Attenuated Total Reflectance-Fourier Transform Infrared spectroscopy. In total 30 microplastic polymers have been identified with an average concentration of 0.71particlesm(-3) (range 0-3particlesm(-3)). Polypropylene, low density polyethylene, polyethylene, polystyrene, polyamide, polymethyl methacrylate, cellophane, and acrylonitrile butadiene styrene polymers were characterized with majority of the microplastics either granular shape, sizes ranging from 125μm to 1.82mm or fibrous with sizes from 150μm to 15.98mm. The microplastics are evident in areas where nearby anthropogenic activities, including oil-rig installations and shipping operations are present.

    NASA Technical Reports Server (NTRS)

    2003-01-01

    The Anti-Atlas Mountains of Morocco formed as a result of the collision of the African and Eurasian tectonic plates about 80 million years ago. This collision destroyed the Tethys Ocean; the limestone, sandstone, claystone, and gypsum layers that formed the ocean bed were folded and crumpled to create the Atlas and Anti-Atlas Mountains. In this ASTER image, short wavelength infrared bands are combined to dramatically highlight the different rock types, and illustrate the complex folding. The yellowish, orange and green areas are limestones, sandstones and gypsum; the dark blue and green areas are underlying granitic rocks. The ability to map geology using ASTER data is enhanced by the multiple short wavelength infrared bands, that are sensitive to differences in rock mineralogy. This image was acquired on June 13, 2001 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils

    Cyberbullying is a worldwide problem affecting mental health, education, safety and general well-being for individuals across the globe. Despite the widespread availability of the Internet, research into prevalence rates of cyberbullying in Qatar is lacking and legislating for the crime has been slow to develop. Recently there have been some positive initiatives in the country such as a Cybercrime Prevention Law, the development of a National ICT Strategy, and a website detailing safe practice guidelines for Internet usage. However, the implementation and usage of these initiatives are still limited and there is a lack of awareness of cyberbullying in Qatar. As a result, the risk factors and consequences among school-aged children are unknown. The current paper presents an evaluation of the legislative and public policy solutions to cyberbullying available in Qatar, and outlines the critical challenges that could potentially face educators in shaping best practice guidelines for the future.

    Objectives Breast cancer incidence rates are rising in Qatar. Although the Qatari government provides subsidised healthcare and screening programmes that reduce cost barriers for residents, breast cancer screening (BCS) practices among women remain low. This study explores the influence of socioeconomic status on BCS among Arab women in Qatar. Setting A multicentre, cross-sectional quantitative survey was conducted with 1063 Arab women (87.5% response rate) in Qatar from March 2011 to July 2011. Women who were 35 years or older and had lived in Qatar for at least 10 years were recruited from seven primary healthcare centres and women's health clinics in urban and semiurban regions of Qatar. Associations between socioeconomic factors and BCS practice were estimated using χ2 tests and multivariate logistic regression analyses. Results Findings indicate that less than one-third of the participants practised BCS appropriately, whereas less than half of the participants were familiar with recent BCS guidelines. Married women and women with higher education and income levels were significantly more likely to be aware of and to practise BCS than women who had lower education and income levels. Conclusions Findings indicate low levels of awareness and low participation rates in BCS among Arab women in Qatar. Socioeconomic factors influence these women's participation in BCS activities. The strongest predictors for BCS practice are higher education and higher income levels. Recommendations Additional research is needed to explore the impact of economic factors on healthcare seeking behaviours in the Middle Eastern countries that have a high national gross domestic product where healthcare services are free or heavily subsidised by the government; promotion of BCS and intervention strategies in these countries should focus on raising awareness about breast cancer, the cost and benefit of early screening for this disease, particularly among low-income women.

    Leishmaniasis in its cutaneous form is a public health problem in Morocco. The objectives of this study were to assess the development of its epidemiological profile, identify the relevant species, and determine the location of the identified cases and their distribution by year, by sex, and by age. This retrospective epidemiological study covers a period of 88 years and concerns all reported cases of cutaneous leishmaniasis (CL) in Morocco from the first description in 1922 until 2010. During this period, 56,194 cases have been reported; they account for 95.7% of all cases of leishmaniasis (n = 58,710). The endemicity of CL has changed over time. The increase in its incidence is likely to be explained both by improved reporting and by a real increase in the number of cases.

  2. Pediatric oncology in Morocco: achievements and challenges.

    2012-03-01

    Cancer in children is quickly becoming one of the leading causes of non traumatic death among children. In pediatric oncology, palliative care is a primary component of the cancer control plan. In low income countries also known as emerging nations or developing countries access to adequate care remains a challenge for most pediatric oncology patients. In Morocco the situation has dramatically improved in the last few years as both the government and NGOs have become more aware of the importance and urgency of the issue. The incidence of cancer in patients under 15 years of age in Morocco is estimated to be 1000 new cases per year and the incidence of leukemia to be 100 new cases diagnosed per year. Pediatric cancer patients are mostly managed by public hospitals. Thus they are highly influenced by the Moroccan public health system, which is now considering cancer management a priority. Since health cover is very limited, most chemotherapy drugs were purchased by local parent associations. Recently, a new large Moroccan NGO (ALSC) provides anti-cancer drugs to all government-run oncology units. Despite all the progress, Morocco has witnessed in the pediatric oncology field, the palliative aspect of the care is not yet organized. Pediatric oncology is supported by the work of the National Society of Pediatric Oncolgy. The opioide therapy is available. However its use is strongly limited by the current restrictive and obsolete legislation which represents a major barrier to care. Despite the latest progress, pediatric oncology in Morocco still needs to improve in order to achieve performances comparable to those of the developed world. These improvements include better survival rates, less treatment abandonment, developing new techniques, improving quality of life and creating data collection teams. In order for this action to succeed all the stakeholders (government, NGOs, medical societies, oncology teams) must work together and coordinate their efforts.

    As with many other areas in the world, the application of horizontal well technology in Qatar has changed the {open_quotes}old time{close_quotes} reservoir development philosophy and approach. QGPC`s first experience with this technology was for increased injectivity in an upper Jurassic reservoir which is comprised by alternating high and low permeable layers. The first well drilled in 1990 offshore was an extreme success and the application was justified for fieldwide implementation. Huge costs were saved as a result. This was followed by 2 horizontal wells for increased productivity in a typically tight (< 5 mD) chalky limestone of Cretaceous age. A fourth offshore well drilled in a thin (30 ft) and tight (10-100 mD) Jurassic dolomite overlaying a stack of relatively thick (25-70 ft) and {open_quotes}Watered Out{close_quotes} grain and grain-packstones, (500-4500 mD) indicated another viable and successful application. A similar approach in the Onshore Dukhan field has been adopted for another Upper Jurassic reservoir. The reservoir is 80 ft thick and is being developed by vertical wells. However, permeability contrast between the upper and lower cycles had caused preferential production and hence injection across the lower cycles, leaving the upper cycles effectively undrained. Horizontal wells have resulted in productivity and injectivity improvements by a factor 3 to 5 that of vertical wells. Therefore a field wide development scheme is being implemented. 3D seismic and the imaging tools, such as the FMS, reconciled with horizontal cores have assisted in understanding the lateral variation and the macro and micro architectural and structural details of these reservoirs. Such tools are essential for the optimum design of horizontal wells.

    Samples of atmospheric dust from Qatar have been collected and analyzed for major and trace elemental composition. Twenty-one samples were collected in 2014 and 2015 from Doha, Al Khor, Katara, Sealine, and Al Waab by a variety of techniques. Some samples were collected during the megastorms that occurred in April 2015. Back trajectories were determined for each sample using the NOAA HYSPLIT model over a 50 hour time interval. Our samples were about equally divided between northerly (n=12; northern Saudi Arabia, Kuwait or Iraq) and southerly (n=8; SE Saudi Arabia, United Arab Emirates and Oman) sources. One sample originated directly westward, in Saudi Arabia. Samples were microwave-assisted total acid digested (HF+HCl+HNO3) and analyzed by inductively coupled plasma-mass spectroscopy (ICP-MS) and inductively coupled plasma-optical emission spectroscopy (ICP-OES). There are only 12 out of 23 elements for which the Qatari dust was enriched relative to upper continental crust (UCC). Calcium was especially enriched at 400% relative to UCC. About 33% of the total sample mass was CaCO3, reflecting the composition of surface rocks in the source areas. Of the elements typically associated with anthropogenic activity, Ag, Ni and Zn were the most enriched relative to UCC, with enrichment factors of 182%, 233% and 209%, respectively. Others like Pb and V were not significantly enriched, with enrichment factors of 25% and 3%, respectively. The major elements Al, Mn and Fe were depleted relative to UCC because of the strong enrichment in CaCO3, with enrichment factors of -58%, -35% and -45% respectively. We separately averaged the samples with northern and southern origins to see if composition could be used to identify source. Only three elements had a statistical difference. Pb and Na were higher in the samples from the Se while Cr was higher in those from the north.

  7. Seasonal Variability in Tropospheric Ozone Distribution Over Qatar

    NASA Astrophysics Data System (ADS)

    Ayoub, Mohammed; Ackermann, Luis

    2015-04-01

    We report on the vertical distribution and seasonal variability in tropospheric ozone over the Middle East through one year of weekly ozonesondes launched from Doha, Qatar during 2014. A total of 49 2Z-V7 DMT/EN-SCI Electrochemical Concentration Cell (ECC) ozonesondes employing a 1% buffered potassium iodide solution (KI), coupled with iMet-1-RS GPS radiosondes were launched around 1300 local time. The authors used the SkySonde telemetry software (developed by CIRES and NOAA/ESRL) and developed robust in-house data quality assurance and validation methodologies. The average height of the thermal tropopause is between 15-17.5 km (125-85 hPa). Monthly average relative humidity around the tropopause shows an enhancement during the months of June through the beginning of October. Monthly average temperature profiles show the development of the subtropical subsidence inversion around 5-6 km (450-520 hPa) between the months of April through October. The subsidence inversion is strongest during the months of June and July and is accompanied by a sharp drop in relative humidity over a 100-300 m in the vertical. The monthly average ozone background concentration between the Planetary Boundary Layer (PBL) height and the subsidence inversion increases from 50 ppb in the winter to almost 80 ppb in the summer months. An enhancement of up to 50% in the average ozone in the mid-to-upper troposphere (above the subsidence inversion) is strongest during the summer months (June through September) and results in average concentrations between 80-100 ppb. In the upper troposphere (above 13 km/200 hPa) ozone concentrations are highest during the spring and summer months. This is coupled with a drop in the average height of the tropopause. HYSPLIT back-trajectory analysis shows the enhancement in mid-to-upper tropospheric ozone in the summer is due to persistent high pressure over the Middle East between the months of June through September.

    2015-04-01

    The Kingdom of Morocco is a country of 33 million people where about thirty French schools enroll 32,000 students including a majority of Moroccans. The Rabat Center includes several institutions enrolling 5,700 students aged 10 to 18 years old whose High School René Descartes is directed by the A.E.F.E, "Agency for French Teaching Abroad". Sixteen professors teach S.V.T. "Sciences de la Vie et de la Terre" that focuses on biology and geology. The programs involved are French but the biology-geology colleagues seek to place the teaching of geology in the context of Morocco through the choice of Moroccan examples. (https://sites.google.com/site/aefesvtmaroc/) Morocco's geology lends itself to this approach! The laboratory is equipped with a seismometer in the network "Sismos to School" (https://sites.google.com/a/lycee-descartes.ma/rabt_sismo/home) and we have the equipment necessary for making thin sections of the Moroccan rocks for practical work on a polarizing microscope. We organize several field trips: On a half-day in the region of Rabat, 12-year old pupils of "5ème", learn about reading the landscape and studying sedimentary rocks such as marls and sandstones. On a 3-day excursion in the region of Azrou, the16-year old pupils of "première scientifique" study the tectonic context of formation of mineral resources. A 2-day trip in the region of Oulmès, the17-year old pupils of "terminale scientifique" (the last year in the French system finishing with the "baccalaureate") study continental crust, tectonics and geothermal energy. These field trips will be presented in this poster. Students make field studies: observation, testing, photography, drawing and taking notes. Some works are evaluated during the field trip, others are the subject of home work: preparing a slide show, an audio recording work...

  10. Transit Timing Variation Measurements of WASP-12b and Qatar-1b: No Evidence Of Additional Planets

    NASA Astrophysics Data System (ADS)

    Collins, Karen A.; Kielkopf, John F.; Stassun, Keivan G.

    2017-02-01

    WASP-12b and Qatar-1b are transiting hot Jupiters for which previous works have suggested the presence of transit timing variations (TTVs) indicative of additional bodies in these systems—an Earth-mass planet in WASP-12 and a brown-dwarf mass object in Qatar-1. Here, we present 23 new WASP-12b and 18 new Qatar-1b complete (or nearly complete) transit observations. We perform global system fits to all of our light curves for each system, as well as RV and stellar spectroscopic parameters from the literature. The global fits provide refined system parameters and uncertainties for each system, including precise transit center times for each transit. The transit model residuals of the combined and five minute binned light curves have an rms of 183 and 255 parts per million (ppm) for WASP-12b and Qatar-1b, respectively. Most of the WASP-12b system parameter values from this work are consistent with values from previous studies, but have ∼40%–50% smaller uncertainties. Most of the Qatar-1b system parameter values and uncertainties from this work are consistent with values recently reported in the literature. We find no convincing evidence for sinusoidal TTVs with a semi-amplitude of more than ∼35 and ∼25 s in the WASP-12b and Qatar-1b systems, respectively.

    2015-02-25

    The objectives of this study were to assess the needs of schoolchildren relating to medication safety and to develop and implement a health promotion programme in Qatar. Semi-structured interviews were completed with teachers, nurses and school administrators at 2 primary schools in Doha. Two main themes were identified from these interviews, namely medication basics and medication safety. Subsequently, a 25-minute health promotion programme was developed and delivered to 11 groups of schoolchildren aged 6-10 years. The student groups contained both expatriate and local Qatari students. The programme was evaluated based on perceptions of site representatives, investigators and peer reviewers using a standardized evaluation form. All the evaluators agreed that the programme was beneficial and should be recommended to other schools in Qatar. This study can serve as a prototype for future programmes in the Eastern Mediterranean Region and elsewhere.

    2014-09-01

    The World Health Organization recommends that all countries develop a cancer control program. Qatar is the first country in the Gulf Cooperation Council to develop such a plan, with its National Cancer Strategy 2011-2016. Three years into implementation, meaningful progress has been made, particularly in reducing patient waiting times, creating a multidisciplinary approach to cancer treatment, and fostering international research collaboration. Challenges include attracting sufficient numbers of trained health care workers, reaching a diverse population with messages tailored to their needs, and emphasizing cancer prevention and early detection in addition to research and treatment. Qatar's example shows that best practices developed in North America, Western Europe, and Australasia can be assimilated in a very different demographic and cultural context when such approaches are tailored to local characteristics and circumstances.

    Warren, Christopher; Dupont, Jennifer; Abdel-Moati, Mohamed; Hobeichi, Sanaa; Palandro, David; Purkis, Sam

    2016-04-30

    A framework is proposed for utilizing remote sensing and ground-truthing field data to map benthic habitats in the State of Qatar, with potential application across the Arabian Gulf. Ideally the methodology can be applied to optimize the efficiency and effectiveness of mapping the nearshore environment to identify sensitive habitats, monitor for change, and assist in management decisions. The framework is applied to a case study for northeastern Qatar with a key focus on identifying high sensitivity coral habitat. The study helps confirm the presence of known coral and provides detail on a region in the area of interest where corals have not been previously mapped. Challenges for the remote sensing methodology associated with natural heterogeneity of the physical and biological environment are addressed. Recommendations on the application of this approach to coastal environmental risk assessment and management planning are discussed as well as future opportunities for improvement of the framework.

    A study on (137)Cs, (40)K, (226)Ra, (228)Ra, and (238)U was carried out along the EEZ of Qatar. Results serve as the first ever baseline data. The level of (137)Cs (mean value 1.6 ± 0.4 Bq m(-3)) in water filters was found to be in the same order of magnitude as reported by others in worldwide marine radioactivity studies. Results are also in agreement with values reported from other Gulf regions. The computed values of sediment-water distribution coefficients Kd, are lower than the values given by IAEA. Measurements were carried out for bottom sediments, biota samples like fish, oyster, sponge, seashell, mangrove, crab, shrimp, starfish, dugong and algae. The 'concentration factors' reported for biota samples are below the levels published by IAEA and cause no significant impact on human health for seafood consumers in Qatar.

    Drought vulnerability assessment and mapping in Morocco Authors: Yasmina Imani 1, Ouiam Lahlou 1, Si Bennasser Alaoui 1 Paulo Barbosa 2, Jurgen Vogt 2, Gustavo Naumann 2 1: Institut Agronomique et Vétérinaire Hassan II (IAV Hassan II), Rabat Morocco. 2: European Commission, Joint Research Centre (JRC), Institute for Environment and Sustainability (IES), Ispra, Italy. In Morocco, nearly 50% of the population lives in rural areas. They are mostly small subsistent farmers whose production depends almost entirely on rainfall. They are therefore very sensitive to drought episodes that may dramatically affect their incomes. Although, as a consequence of the increasing frequency, length and severity of drought episodes in the late 90's, the Moroccan government decided, to move on from a crisis to a risk management approach, drought management remains in practice mainly reactive and often ineffective. The lack of effectiveness of public policy is in part a consequence of the poor understanding of drought vulnerability at the rural community level, which prevents the development of efficient mitigation actions and adaptation strategies, tailored to the needs and specificities of each rural community. Thus, the aim of this study is to assess and map drought vulnerability at the rural commune level in the Oum Er-Rbia basin which is a very heterogeneous basin, showing a big variability of climates, landscapes, cropping systems and social habits. Agricultural data collected from the provincial and local administrations of Agriculture and socio-economic data from the National Department of Statistics were used to compute a composite vulnerability index (DVI) integrating four different components: (i) the renewable natural capacity, (ii) the economic capacity, (iii) human and civic resources, and (iv) infrastructure and technology. The drought vulnerability maps that were derived from the computation of the DVI shows that except very specific areas, most of the Oum er Rbia

  20. Comparison of intestinal parasitic infection in newly arrived and resident workers in Qatar

    PubMed Central

    2011-01-01

    Background The rapid growth of Qatar in the last two decades has been associated with an enormous expansion of building programs in its cities and in the provision of new service industries. This in turn has attracted a large influx of immigrant workers seeking employment in jobs associated with food handling, domestic service and the building industry. Many of these immigrants come from countries in the tropics and subtropics where intestinal parasitic infections are common. Methods We analyzed intestinal parasitic infections recorded in 2008 among immigrant and long-term resident workers in Doha city, Qatar (n = 1538). Stool examinations were carried out at the Hamad Medical Corporation and at the Medical Commission in Doha using standard procedures. Results Overall, 21.5% of subjects were infected with at least one of the species recorded (8 helminth and 4 protozoan species; the highest prevalence was for hookworms = 8.3%) and there were strong regional effects on prevalence of helminths, with subjects from North East Africa and Nepal showing particularly high prevalence. Most helminths declined in prevalence in subjects that acquired residency status in Qatar, especially among female subjects, but there was a marked exception among male Nepalese workers, who continued to harbour helminth infections (notably hookworms) after they became residents. Contrary to all other regional groups the prevalence of Giardia duodenalis was higher among Nepalese residents compared with new arrivals, while Blastocystis hominis infections were more common among residents of all regions, and especially among North East Africans. Conclusions Our analysis has identified male Nepalese workers as a particular risk group continuing to harbour hookworm infection and G. duodenalis as residents, and subjects from North East Africa are as particularly likely to acquire B. hominis infection after settling in the country. These conclusions have important implications for the health

The analytical techniques of scanning electron microscopy (SEM) and X-ray powder diffraction (XRPD) were used to study the samples. For the samples from Qatar, six of the 19 (32%) contained galena (lead sulfide, PbS)--all as the main component. However, for the samples from Yemen, five of the ten (50%) samples contained galena as the main component, with another three having it present as a minor component. Overall, the other main components were found to be: amorphous carbon (3), iron oxides (hematite, Fe2O3; and goethite, FeO(OH)) (1), quartz (SiO2) (1), sassolite (H3BO3) (5), talc (Mg3Si4O10(OH)2) (1), and zincite (ZnO) (7).

    The causes of infectious diarrhea among the migrant worker population in Qatar are not well understood. We conducted a prospective observational study to understand the demographic and clinical characteristics and infectious causes of diarrhea among migrant workers in Doha, Qatar. A total of 126 male workers presenting to the Qatar Red Crescent Worker's Health Center outpatient clinic or emergency department were studied over a 5-month period in 2015-2016. Epidemiologic surveys were administered to all subjects and the prevalence of 22 different stool pathogens was determined using multiplex polymerase chain reaction (PCR) (FilmArray(®) Gastrointestinal PCR). A target pathogen was identified in 62.7% of subjects. Enteropathogenic Escherichia coli was the most prevalent pathogen and was detected in 24.6% of subjects, followed by Salmonella (22.2%), enteroaggregative E. coli (15.1%), Giardia lamblia (9.5%), and enterotoxigenic E. coli (8.7%). Multiple pathogens were identified in 49.3% of positive stool samples. In a multivariable analysis, the presence of a heart rate ≥ 90 (adjusted odds ratio [OR] = 3.7, 95% confidence interval [CI] = 1.4-10.0) and > 5 fecal leukocytes/high-power field (adjusted OR = 2.8, 95% CI = 1.2-7.0) were significant predictors of detecting an acute inflammatory pathogen by PCR. Use of multiplex PCR enabled the detection of gastrointestinal pathogens in a high proportion of cases, illustrating the utility of this diagnostic tool in epidemiologic studies of infectious diarrhea.

    To compare the nature and determinants of child discipline in Qatar and Palestine among young adults through retrospective survey to develop legislation, policies and interventions for effective prevention of child maltreatment, and educational materials to promote positive discipline among parents and caregivers. Cross-sectional random household surveys were conducted in each country (Qataris N=697, Palestinians N=2064) using ISPCAN Child Abuse Screening Tool-Retrospective (ICAST-R) for young adults (18-24 years), to investigate child discipline methods into the maltreatment range. Qatari young adults were more educated (p<0.001) and had more full-time employment (p=0.004) than Palestinian young adults. Qatar reported lower physical and emotional abuse compared to their counterparts in Palestine, e.g. Hit/Punch, Kick (p<0.001) and Insult/Criticize, Threaten to be hurt/killed (p<0.001). Qatari participants found any harsh discipline they received in childhood was not reasonable and not justified compared to Palestinian participants. The more advantaged Qatari population was less likely to experience disciplinary methods that experts developing the ICAST-R defined as abuse compared to Palestinians where the higher incidence of child abuse could be attributed to lower economic advantage, lower level of education and greater exposure to violence. Suggestions are made for future studies in Qatar and Palestine to develop survey methodology with a more culturally appropriate level of intrusion, such as indirect yet meaningful child maltreatment questions.

  4. A road map to Translational Medicine in Qatar and a model for the world

    Translational Medicine (TM) in Qatar is part of a concerted effort of the Qatari medical and scientific leadership supported by a strong political will by Qatari authorities to deliver world-class health care to Qatari residents while participating in the worldwide quest to bridge the gap between bench-to-bedside-to-community. TM programs should embrace the Qatar National vision for research to become an international hub of excellence in research and development, based on intellectual merit, contributing to global knowledge and adhering to international standards, to innovate by translating new and original ideas into useful applications, to be inclusive at the national and international level, to build and maintain a competitive and diversified economy and ultimately improve the health and well-being of the Qatar’s population. Although this writing focuses on Qatar, we hope that the thoughts expressed here may be of broader use for the development of any TM program particularly in regions where an established academic community surrounded by a rich research infrastructure and/or a vibrant biotechnology enterprise is not already present.

    Atmospheric surface layer is the interaction medium between atmosphere and Earth's surface. Better understanding of its turbulence nature is essential in characterizing the local weather, climate variability and modeling of turbulent exchange processes. The importance of Middle East region, with its unique geographical, economical and weather condition is well recognized. However, high quality micrometeorological observational studies are rare in this region. Here we show experimental results from micrometeorological observations from an experimental site in the coastal region of Qatar during August-December 2015. Measurements of winds are obtained from three sonic anemometers installed on a 9 m tower placed at Al Ghariyah beach in northern Qatar (26.08 °N, 51.36 °E). Different surface layer characteristics is analyzed and compared with earlier studies in equivalent weather conditions. Monthly statistics of wind speed, wind direction, temperature, humidity and heat index are made from concurrent observations from sonic anemometer and weather station to explore variations with surface layer characteristics. The results also highlights potential impact of sea breeze circulation on local weather and atmospheric turbulence. The observed daily maximum temperature and heat index during morning period may be related to sea breeze circulations. Along with the operational micrometeorological observation system, a camera system and ultrasonic wave measurement system are installed recently in the site to study coastline development and nearshore wave dynamics. Overall, the complete observational set up is going to provide new insights about nearshore wind dynamics and wind-wave interaction in Qatar.

    The objective of our study was to describe the molecular support of carbapenem resistance from randomly selected clinical isolates of multidrug-resistant (MDR) Acinetobacter baumannii as a pilot study from the Hamad Medical Corporation (HMC), Qatar. Results of our report will be used to study carbapenemases using molecular techniques in all isolated MDR A. baumannii. Forty-eight MDR A. baumannii were randomly selected from isolates preserved at HMC. Identification of all isolates was confirmed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Antibiotic resistance was tested phenotypically by Phoenix and confirmed by Etest. The molecular support of carbapenemases (bla OXA-23, bla OXA-24, bla OXA-58, bla NDM) was investigated by real-time PCR. The epidemiologic relatedness of the isolates was verified by phylogenetic analysis based on partial sequences of CsuE and bla OXA-51 genes. All 48 isolates were identified as A. baumannii and were confirmed to be resistant to most antibiotics, especially meropenem, imipenems, ciprofloxacin, levofloxacin, amikacin, gentamicin and most of the β-lactams; they were sensitive to colistin. All the isolates were positive for bla OXA-23 and negative for the other tested carbapenemase genes. Clonality analysis demonstrated that different lineages were actually circulating in Qatar; and we suggest that an outbreak occurred in the medical intensive care unit of HMC between 2011 and 2012. Here we report the emergence of MDR A. baumannii producing the carbapenemase OXA-23 in Qatar.

    The parasite fauna of stray cat populations, comprising mainly helminth parasites, is described for the first time from the arid environment of the Qatar peninsula. During the winter and summer months of 2005, 824 faecal samples were examined from six sites in Qatar. Up to seven species of parasites were identified, six of which were nematodes - Strongyloides stercoralis as the most prevalent (18.4%), followed by Aelurostrongylus abstrusus (7.5%), Toxocara cati (6.1%), Ancylostoma tubaeforme (5.9%) and Physaloptera sp. (4.8%) and Toxascaris leonina (0.7%) - and one sporozoan species, Isospora felis (0.5%). Unidentified cestode eggs were also recovered from 10.7% of samples examined. The parasite species were found to be highly overdispersed in faecal samples from all sites, whereas the prevalence and intensity of infections were influenced by site and season. Infection levels tended to be higher during the winter season, especially in the case of A. abstrusus and A. tubaeforme, when conditions of temperature and humidity were more favourable for the development of egg and/or larval stages of parasites compared with the extremely hot and dry summer months. The results are discussed in relation to the distribution of the cat population in the vicinity of Doha and its outskirts and the potential threat of parasite transmission to human communities in Qatar.

    The education system in Qatar comprises of both private schools, which receive money through student fees, and public schools, which are fully government-funded. In the mid-2000s, Qatar started its transition towards an independent school model with the aim of eventually converting all public schools into government-supported independent schools. The idea was to give public schools more autonomy in terms of hiring decisions, adoption of curriculum and textbooks, and budget spending, enabling them to emulate some of the private schools' strategies for turning out successful students. This study examines evidence from the 2006-2012 administrations of the Program for International Student Assessment (PISA) in Qatar in order to evaluate whether or not recent educational reform efforts in this country have succeeded in bridging the literacy divide between private and public schools. The results, presented in a number of detailed tables and discussed in the last part of the article, indicate that there is a significant difference in key literacy skills between the two types of schools. Private schools were found to outperform their public counterparts in areas such as mathematics, reading and science, both before and after controlling for important student-level differences, and this gap has evidently persisted from 2006 to 2012.

  9. Energy trump for Morocco: the oil shales

    The mainstays of the economy in Morocco are still agriculture and phosphates; the latter represent 34% of world exports. Energy demand in 1985 will be probably 3 times that in 1975. Most of the oil, which covers 82% of its energy needs, must be imported. Other possible sources are the rich oil shale deposits and nuclear energy. Four nuclear plants with a total of 600 MW are projected, but shale oil still will play an important role. A contract for building a pilot plant has been met recently. The plant is to be located at Timahdit and cost $13 million, for which a loan from the World Bank has been requested. If successful in the pilot plant, the process will be used in full scale plants scheduled to produce 400,000 tons/yr of oil. Tosco also has a contract for a feasibility study.

    Recent advances in medical technology and key discoveries in biomedical research have the potential to improve human health in an unprecedented fashion. As a result, many of the Arab Gulf countries, particularly Qatar are devoting increasing resources toward establishing centers of excellence in biomedical research. However, there are challenges that must be overcome. The low profile of private medical institutions and their negligible endowments in the region are examples of such challenges. Business-type government controlled universities are not the solution for overcoming the challenges facing higher education and research programs in the Middle East.During the last decade, Qatar Foundation for Education, Science and Community Development has attracted six branch campuses of American Institutions of higher learning to the Education City in Qatar, a 2500-acre area, which is rapidly becoming a model of integrating higher education and research in the region. Not-for profit, time-tested education institutions from abroad in public-private partnership with local organizations offer favorable conditions to build robust research programs in the region. Weill Cornell Medical College in Qatar (WCMC-Q) of Cornell University is an example such an institution. It is the first and only medical school in Qatar.WCMC-Q's interwoven education, research and public health based framework lays a sturdy foundation for developing and implementing translational medicine research programs of importance to the State of Qatar and Middle Eastern nations. This approach is yielding positive results. Discoveries from this program should influence public policy in a positive fashion toward reducing premature mortality and morbidity due to diabetes, obesity, heart disease and cancer, examples of health conditions commonly encountered in Qatar.

  17. Carboniferous sedimentation and tectonics in southern Morocco

    1988-08-01

    The Carboniferous rocks of southern Morocco record the gradual change from the extensional tectonic style of the early Paleozoic to a compressional regime. During the Tournaisian and early Visean, northwest compression formed a rising anticline in the Anti-Atlas, which provided sediments to shallow marine basins formed in the flanking synclines. During the late Visean, tectonic activity increased markedly, and northward-downthrowing normal/oblique slip faulting formed submarine fault scarps. Turbidity currents and debris flows together with giant exotic blocks were shed northward from these scarps. The turbidity currents were deflected eastward to flow down the axes of these small easterly plunging marine basins. A late Visean phase of minor folding with locally developed cleavage and quartz veining closed these basins. The folded sequences are unconformably overlain by uppermost Visean fluvial sediments deposited from northward and eastward-flowing rivers. During the Pennsylvanian, collisional tectonics recorded in the Moroccan Meseta to the north were probably responsible for thrust faulting and the formation of a high-angle cleavage. Thick (up to 4.5 km) sandstones and conglomerates with red mudstones, paleosols, and coals are preserved on the fringes of the area. These were deposited by southeast-flowing rivers and are interpreted as the eroded remnants of a syn-postorogenic molasse deposited in a major foredeep south of the main orogen.

  18. Gas potential of the Rharb Basin, Morocco

    1995-08-01

    The Rharb basin in northern Morocco is a Tertiary foreland filled by clastic series during Miocene and Pliocene times These sediments, derived from the Prerif to the North-East and the Meseta to the South, are characterized by two main turbiditic sequences during much of the Upper Tortonian/Messinian and Lower Pliocene. These deep water sand deposits were probably related to both uplifting of the Rif and prerif and relative change of sea level. Although the first oil discovery in the basin was made by the beginning of the 1920`s and that over 25 billions cf of gas have been discovered by exploration drilling, the problem still facing exploration in the area is seismic resolution and reprocessing. Recent studies, based on high seismic resolution techniques and general integrated basin study have permitted to gain a deep insight of stratigraphy and distribution of deep water sand within the Upper Miocene series and their fluid content and provide critical data for evaluating hydrocarbon potential. Such evaluation combined with structural configuration and seals allows assessment of different prospects for gas exploration. Out of more 100 amplitude anomalies identified in the area based on new exploration concepts, 7 are recently drilled with 4 discoveries and 8 are proposed for drilling.

    2014-01-01

    Background To ensure the oral health of a population, clinicians must deliver appropriate dental services, and local communities need to have access to dental care facilities. However, establishment of this infrastructure must be based on reliable information regarding disease prevalence and severity in the target population. Objectives The aims of this study were to measure the incidence of dental caries in school children aged 12–14 throughout Qatar, including the influence of socio-demographic factors. Materials and methods A cross-sectional study was conducted in Qatar from October 2011 to March 2012. A total of 2113 children aged 12–14 were randomly selected from 16 schools located in different geographic areas. Three calibrated examiners using World Health Organization (WHO) criteria to diagnose dental caries performed the clinical examinations. Data analyses were subsequently conducted. Results The mean decayed, missing, and filled teeth index values were respectively 4.62 (±3.2), 4.79 (±3.5), and 5.5 (±3.7), for 12, 13, and 14 year-old subjects. Caries prevalence was 85%. The mandibular incisors and canines were least affected by dental caries, while maxillary and mandibular molars exhibited the highest incidence of dental caries. Dental caries were affected by socio-demographic factors; significant differences were detected between female and male children, where more female children showed dental caries than male children. In addition, children residing in semi-urban areas showed more dental caries than in urban areas. Conclusion Results indicated that dental caries prevalence among school children in Qatar has reached critical levels, and is influenced by socio-demographic factors. The mean decayed, missing, and filled teeth values obtained in this study were the second highest detected in the Eastern Mediterranean region. PMID:25057232

  20. Physician perceptions of pharmacist roles in a primary care setting in Qatar

    2012-01-01

    Purpose Pharmacists are uniquely trained to provide guidance to patients in the selection of appropriate non-prescription therapy. Physicians in Qatar may not always recognize how pharmacists function in assuring safe medication use. Both these health professional groups come from heterogeneous training and experiences before migrating to the country and these backgrounds could influence collaborative patient care. Qatar Petroleum (QP), the largest private employer in the country, has developed a pharmacist-guided medication consulting service at their primary care clinics, but physician comfort with pharmacists recommending drug therapy is currently unknown. The objective of this study is to characterize physician perceptions of pharmacists and their roles in a primary care patient setting in Qatar. Methods This cross-sectional survey was developed following a comprehensive literature review and administered in English and Arabic. Consenting QP physicians were asked questions to assess experiences, comfort and expectations of pharmacist roles and abilities to provide medication-related advice and recommend and monitor therapies. Results The median age of the 62 (77.5%) physicians who responded was between 40 and 50 years old and almost two-third were men (64.5%). Fourteen different nationalities were represented. Physicians were more comfortable with pharmacist activities closely linked to drug products than responsibilities associated with monitoring and optimization of patient outcomes. Medication education (96.6%) and drug knowledge (90%) were practically unanimously recognized as abilities expected of pharmacists, but consultative roles, such as assisting in drug regimen design were less acknowledged. They proposed pharmacist spend more time with physicians attending joint meetings or education events to help advance acceptance of pharmacists in patient-centered care at this site. Conclusions Physicians had low comfort and expectations of patient

    Re-examination in February 1986 of areas studied by the author in 1966 and 1967 revealed rapid rates of sedimentation and diagenesis along the east coast of the Qatar Peninsula. At Ras UmSa on the northeast side of Qatar, a series of chenier-like beaches and curved spits is building southward under the influence of longshore currents. Beach and spit growth increasingly protects the shoreline and allows tidal flats to form in their lee. As these spits accrete, they become armored on their lagoonal side by beachrock formation. In the last 20 years a spit approximately 1/2 km long has grown, and beachrock has already armored its recurved lagoonal side. At Umm Said on the southeast side of Qatar, seawardly accreting barchan dunes composed of quartz sand have built a 40-km long, 10-km wide sabkha as thick as 30 m. Aerial and ground photographs show that certain dunes near the seaward edge of the sabkha have migrated into the sea and have contributed to shoreline accretion. The observed rate of dune migration suggests that within approximately 100 years the remaining quartz sands are depleted and blown into the sea because there is no replenishment of the dune field. Subsequently, the area reverts to one of carbonate deposition. Fine-grained dolomite is presently precipitating in interstitial brines in the landwardmost portions of this unusual sabkha. In the geologic record, such a deposit would be an anomalous, porous and permeable, cross-bedded, linear, 30-m thick, dolomite-cemented sandstones body encased in carbonate sediments. A modern model such as the one at Umm Said can provide useful clues for determining the origin of similar deposits in ancient rocks.

    Background: The aim of this study was to assess the oral health knowledge behaviour and practices among school children in Qatar. Materials and Methods: A cross-sectional study was carried out in Qatar from October 2011 to April 2012. A total of 2200 school children aged 12–14 years were approached from 16 schools of different areas. The information about oral health knowledge and sources of information was obtained through a self-administrated questionnaire. Data analyses were performed. Results: The overall response rate was (96%). Only (25.8%) of children reported a high level of oral health knowledge. After each meal, tooth brushing was observed by a very low percentage of children (3.7%). About 44.6% of children recognized dental floss as a cleaning device for between the teeth. A large number of children (32.5%) thought incorrectly that one must visit the dentist only in case of pain. A great majority was not aware of cariogenic potential of soft drinks (39%) and sweetened milk (97.8%). Less than half (38.9%) of children actually had heard about fluoride. Only (16.8%) correctly answered the question about sign of tooth decay. Slightly, less than half (48.4%) could not define the meaning of plaque. Parents were the most popular (69.1%), source of oral health information for the children. Conclusion: The oral health knowledge in Qatar is below the satisfactory level. Parents were the most popular source of oral health knowledge for the children followed by dentists, school teachers, and media. PMID:27605993

    Cutaneous leishmaniasis (CL) is a public health problem on a global level because it affects the population of 88 countries. In Morocco, it is widely distributed, caused by Leishmania tropica, Leishmania major and Leishmania infantum rarely. The geographical distribution of different forms of leishmaniasis in Morocco is linked to well described bioclimatic zones. Over the past two decades, the epidemiological situation of CL has changed significantly. It acquire an increasingly epidemic status with geographic expansion to previously free areas and the emergence of overlapping foci of cutaneous leishmaniasis and visceral leishmaniasis in several provinces of Morocco. In this review the evolution of the epidemiological situation and epidemiological factors which influenced the course of it in the past two decades will be reported.

    Background Visceral leishmaniasis (VL) is a neglected parasitic disease that is fatal if left untreated. VL is endemic in Morocco and other countries in North Africa were it mainly affects children from rural areas. In Morocco, the direct observation of Leishmania parasites in bone marrow aspirates and serological tests are used to diagnose VL. Glucantime is the first line of treatment. The objective of this study was to report the costs associated to standard clinical management of pediatric VL from the provider perspective in Morocco. As a secondary objective we described the current clinical practices and the epidemiological characteristics of pediatric VL patients. Methods From March to June 2014 we conducted a survey in eight hospitals treating pediatric VL patients in Morocco. A pro-forma was used to collect demographic, clinical and management data from medical records. We specifically collected data on VL diagnosis and treatment. We also estimated the days of hospitalization and the time to start VL treatment. Costs were estimated by multiplying the use of resources in terms of number of days in hospital, tests performed and drugs provided by the official prices. For patients receiving part of their treatment at Primary Health Centers (PHC) we estimated the cost of administering the Glucantime as outpatient. We calculated the median cost per VL patient. We also estimated the cost of managing a VL case when different treatment strategies were applied: inpatient and outpatient. Results We obtained data from 127 VL patients. The median total cost per pediatric VL case in Morocco is 520 US$. The cost in hospitals applying an outpatient strategy is significantly lower (307 US$) than hospitals keeping the patients for the whole treatment (636 US$). However the outpatient strategy is not yet recommended as VL treatment for children in the Moroccan guidelines. VL diagnosis and treatment regimens should be standardized following the current guidelines in Morocco

    In September 2011 the fortress Al Zubarah, built in 1938 as a typical Arabic fortress and restored in 1987 as a museum, was recorded by the HafenCity University Hamburg using terrestrial laser scanning with the IMAGER 5006h and digital photogrammetry for the Qatar Museum Authority within the framework of the Qatar Islamic Archaeology and Heritage Project. One goal of the object recording was to provide detailed 2D/3D documentation of the fortress. This was used to complete specific detailed restoration work in the recent years. From the registered laser scanning point clouds several cuttings and 2D plans were generated as well as a 3D surface model by triangle meshing. Additionally, point clouds and surface models were automatically generated from digital imagery from a Nikon D70 using the open-source software Bundler/PMVS2, free software VisualSFM, Autodesk Web Service 123D Catch beta, and low-cost software Agisoft PhotoScan. These outputs were compared with the results from terrestrial laser scanning. The point clouds and surface models derived from imagery could not achieve the same quality of geometrical accuracy as laser scanning (i.e. 1-2 cm).

    Objective. To develop, implement, and evaluate a course-based, cross-cultural student interaction using real-time videoconferencing between universities in Canada and Qatar. Design. A professional skills simulation practice session on smoking cessation was run for students in Qatar (n=22) and Canada (n=22). Students role played cases in small group situations and then interacted with colleagues from the other country regarding culturally challenging situations and communication strategies. Assessment. Students were assessed on analytical content and communication skills through faculty member and peer evaluation. Cultural competency outcomes were assessed using a postsession survey. Overall, 92.3% of respondents agreed that learning was enhanced through the cross-cultural exchange, and 94.9% agreed that insight was gained into the health-related issues and needs of people from another culture. Conclusion. A course-based, cross-cultural interaction was an effective method to incorporate cultural competency principles into student learning. Future initiatives should increase direct student interaction and focus on culturally sensitive topics. PMID:25861107

    Cultural life scripts (CLS) are culturally shared cognitive representations of the expected order and timing of important life events in a prototypical life. Through three studies data from Qatar were analysed and compared to previously collected data from Denmark, Turkey, and the US. In Study 1 we examined the CLS of Qatar in order to determine whether the clear segregation of men and women as well as the centrality of religion in this society would influence the CLS. A total of 55 Qatari undergraduates completed the standard CLS task, imaging a Qatari infant of their own as well as the opposite gender. In Study 2 important personal life story events were collected from 83 Qatari undergraduates in order to explore the overlap between remembered life events and CLS events. Study 3 was a reanalysis of CLS data from Denmark, Turkey, and the US. There was a considerable overlap of events across cultures, but we also found that the Qatari CLS showed more gender differences and contained more religious and positive events compared to the other three countries.

    This article presents the results of a patient satisfaction survey carried out in an acute care hospital complex in Doha, Qatar, in the Middle East. The objectives were to determine the level of patient satisfaction as follows: in general, in 18 different patient areas and services, for Qatar citizens and noncitizens, among patients with different sociodemographic characteristics, and in technical and interpersonal areas of care. The quantitative, descriptive survey design involved two 73-item questionnaires, one in English and one in Arabic. It was given to medical, surgical, and obstetric and gynecologic patients. Satisfaction was rated on a 5-point scale, and univariate statistics and chi-square analysis were used to determine frequencies and statistical differences. The response rate was 77%; 84% rated the overall quality of care excellent or very good. Respondents gave nursing services the highest ratings and slightly favored technical over interpersonal care. The results show that patients are willing to participate in the survey process and that the questionnaire is a valuable tool for measuring satisfaction and for obtaining feedback and continuous evaluation of services.

    This study aimed to evaluate the feasibility and psychometric defensibility of implementing a comprehensive objective structured clinical examination (OSCE) on the complete pharmacy programme for pharmacy students in a Middle Eastern context, and to identify facilitators and barriers to implementation within new settings. Eight cases were developed, validated, and had standards set according to a blueprint, and were assessed with graduating pharmacy students. Assessor reliability was evaluated using inter-class coefficients (ICCs). Concurrent validity was evaluated by comparing OSCE results to professional skills course grades. Field notes were maintained to generate recommendations for implementation in other contexts. The examination pass mark was 424 points out of 700 (60.6%). All 23 participants passed. Mean performance was 74.6%. Low to moderate inter-rater reliability was obtained for analytical and global components (average ICC 0.77 and 0.48, respectively). In conclusion, OSCE was feasible in Qatar but context-related validity and reliability concerns must be addressed prior to future iterations in Qatar and elsewhere.

    A survey of the helminths of 658 adult cats from feral urban and suburban populations in Qatar was conducted across all months in 2006 and 2007. Six species of helminths were identified, comprising two cestodes (Taenia taeniaeformis [73.6%] and Diplopylidium acanthotetra [47.1%]) and four nematodes (Ancylostoma tubaeforme [14.7%], Physaloptera praeputialis [5.2%], Toxocara cati [0.8%] and Toxascaris leonina [0.2%]), and 83% of cats were infected with at least one of these. The average number of species harboured was 1.4 and the average worm burden was 55.8 worms/cat. The vast majority of worms (97.6%) were cestodes, nematodes being relatively rare. Prevalence and abundance of infections were analyzed, taking into consideration four factors: year (2006 and 2007), site (urban and suburban), season (winter and summer) and sex of the host. Analyses revealed marked year effects, female host bias in some species and interactions involving combination of factors, but especially sex and season of the year. The results indicate that whilst the majority of adult feral cats in Qatar carry helminth infections, infections are variable between years and subject to annual changes that may reflect climatic and other environmental changes in the rapidly developing city of Doha and its suburban surroundings. Only two species have the potential to infect humans and both were rare among the sampled cats (A. tubaeforme and T. cati).

    We report the discovery and initial characterization of Qatar-2b, a hot Jupiter transiting a V = 13.3 mag K dwarf in a circular orbit with a short period, P{sub b} = 1.34 days. The mass and radius of Qatar-2b are M{sub P} = 2.49 M{sub J} and R{sub P} = 1.14 R{sub J}, respectively. Radial-velocity monitoring of Qatar-2 over a span of 153 days revealed the presence of a second companion in an outer orbit. The Systemic Console yielded plausible orbits for the outer companion, with periods on the order of a year and a companion mass of at least several M{sub J}. Thus, Qatar-2 joins the short but growing list of systems with a transiting hot Jupiter and an outer companion with a much longer period. This system architecture is in sharp contrast to that found by Kepler for multi-transiting systems, which are dominated by objects smaller than Neptune, usually with tightly spaced orbits that must be nearly coplanar.

  11. The diabetes-obesity-hypertension nexus in Qatar: evidence from the World Health Survey

    2014-01-01

    Background As countries develop economically, an “epidemiological transition” occurs whereby a set of chronic diseases increasingly becomes a country’s health challenge. Against this background, this paper examines the most common conditions associated with the prevalence of diabetes in Qatar, with a specific focus on the diabetes-obesity-hypertension nexus. Methods We analyzed data from the World Health Organization’s World Health Survey conducted in the State of Qatar in 2006. The survey included demographic, anthropometric, and blood chemistry measurements. Using multivariate logistical regression analysis, we assessed the most common conditions associated with diabetes, using both objective and subjective measures of diabetes. The objective measures relied on random blood sugar tests, and the subjective measure included respondents who affirmatively answered the question on diabetes diagnosis. We repeated our analysis on respondents who had blood glucose levels high enough to be considered diabetic/glucose intolerant but did not answer affirmatively on the question of diabetes diagnosis. Results When using the objective measure of diabetes, the following conditions appeared significant: obesity (OR = 1.5, 95% CI = 1.2 – 1.9), higher income (OR = 1.4, 95% CI = 1.0 – 1.9), high cholesterol (OR = 1.4, 95% CI = 1.0 – 1.9), having Qatari origin (OR = 1.3, 95% CI = 1.0 – 1.7), and increasing systolic blood pressure (SBP) 120–139 mmHg (OR = 1.5, 95% CI = 1.2 – 2.0), SBP 140–159 mmHg (OR = 2.2, 95% CI = 1.6 – 3.1), SBP > 160 mmHg (OR = 3.2, 95% CI = 2.0 – 5.3). Similar results were obtained using the subjective measure of diabetes as a dependent variable. When applied to the group of respondents that included pre-diabetics and those who did not know they were diabetic, obesity and hypertension appeared as the only statistically significant explanatory variables. Conclusion High

    Objectives To determine optimum measurements for abdominal obesity and to assess the prevalence and determinants of metabolic syndrome in Qatar. Design National health survey. Setting Qatar National STEPwise Survey conducted by the Supreme Council of Health during 2012. Participants 2496 Qatari citizens aged 18–64 representative of the general population. Primary and secondary outcome measures Measure of obesity (body mass index, waist circumference or waist-to-height ratio) that best identified the presence of at least 2 other factors of metabolic syndrome; cut-off values of waist circumference; frequency of metabolic syndrome. Results Waist circumference ≥102 for men and ≥94 cm for women was the best predictor of the presence of other determinants of metabolic syndrome (raised blood pressure, fasting blood glucose, triglycerides and reduced high-density lipoprotein cholesterol). Using these values, we identified 28% of Qataris with metabolic syndrome, which is considerably lower than the estimate of 37% calculated using the International Diabetes Federation (IDF) criteria. Restricting the analysis to participants without known elevated blood pressure, elevated blood sugar or diabetes 16.5% would be classified as having metabolic syndrome. In a multivariable logistic regression analysis, the prevalence of metabolic syndrome increased steadily with age (OR=3.40 (95% CI 2.02 to 5.74), OR=5.66 (3.65 to 8.78), OR=10.2 (5.98 to 17.6) and OR=18.2 (7.01 to 47.5) for those in the age group ‘30–39’, ‘40–49’, ‘50–59’, ‘60–64’ vs ‘18–29’; p<0.0001), decreased with increasing educational attainment (OR=0.61 (0.39 to 0.96) for those who attained ‘secondary school or more’ compared with ‘less than primary school’; p=0.03) and exercise (OR=0.60 (0.42 to 0.86) for those exercising ≥3000 vs <600 MET-min/week; p=0.006) but was not associated with smoking or diet.

    Objectif : Evaluer les perceptions et attitudes des fumeurs de pipe à eau (shisha) au Qatar en ce qui concerne les risques sanitaires associés à l'addiction et déterminer leurs intentions d'arrêter.Méthodes : Une enquête transversale a été réalisée auprès de 181 fumeurs de pipe à eau. Les participants ont été approchés dans des lieux publics ainsi que dans des cafés à shisha au Qatar. Le questionnaire a inclus des items liés aux perceptions, aux attitudes et aux intentions de s'arrêter. Des études statistiques descriptives et déductives ont été réalisées pour analyser les données, avec P ⩽ 0,05 considéré comme statistiquement significatif.Résultats : Près de 44% des répondants pensaient que fumer une pipe à eau était plus sûr que fumer des cigarettes, et plus de 70% ne verraient pas d'inconvénient à ce que leurs enfants se mettent à fumer la pipe à eau. De plus, plus de la moitié des fumeurs actuels voulaient arrêter de fumer la shisha à un moment ou à un autre et 17% indiquaient qu'une préoccupation relative à leur santé était le facteur de motivation principal dans leur intention d'arrêter.Conclusion : Une large proportion de fumeurs de shisha la considérait comme une alternative plus sûre que les cigarettes, mais ils admettaient volontiers qu'ils avaient l'intention d'arrêter. Ces résultats soulignent la nécessité d'élaborer des interventions à visée éducative et des campagnes de sensibilisation ainsi que d'imposer des lois strictes relatives à l'utilisation de la pipe à eau dans des lieux publics au Qatar.

    1988-03-01

    A hydrodynamic model is described to account for oil and gas occurrences in the Cretaceous of offshore Qatar, in the Arabian Gulf. Variable and inconsistent fluid levels and variable formation water potentials and salinities cannot be explained by combinations of stratigraphic and structural trapping. Indeed, there is no structural closure to the southwest of the oil and gas accumulations. The water-potential and salinity data and oil distribution are consistent with this model and indicate that a vigorous hydrodynamic system pervades the Cretaceous of the Arabian Gulf region. Extensive upward cross-formational discharge is taking place in the North Area. This cross-formation water flow could be partly responsible for localized leaching and reservoir enhancement in the chalky limestones.

    Background: Type II diabetes mellitus (DM) is one of the leading chronic diseases in Qatar as well as worldwide. However, the risk factors for DM in Qatar and their prevalence are not well understood. We conducted a case-control study with the specific aim of estimating, based on data from outpatients with DM in Qatar (cases) and outpatient/inpatient controls, the association between demographic/lifestyle factors and DM. Methods: A total of 459 patients with DM from Hamad General Hospital (HGH) outpatient adult diabetes clinics, and 342 control patients from various outpatient clinics and inpatient departments within Hamad Medical Corporation (HMC) (years 2006–2008), were recruited. The association between risk factors and DM was evaluated using bivariate and multivariable logistic regression analyses. In addition to odds ratios (OR) and 95% confidence intervals (95% CI), we estimated the population attributable risk fractions for the DM demographic/lifestyle risk factors. Results: Qatari nationality was the strongest risk factor for DM (adjusted OR = 5.5; 95% CI = 3.5–8.6; p < 0.0001), followed by higher monthly income (defined as ≥ 3000 Qatari Riyals, adjusted OR = 5.1; 95% CI = 3.0–8.7; p < 0.0001), age >65 years (adjusted OR = 3.3; 95% CI = 0.9–11.4; p = 0.06), male gender (adjusted OR = 2.9; 95% CI = 1.8-4.8; p < 0.0001), obesity (BMI ≥ 30, adjusted OR = 2.2; 95% CI = 1.5-3.2; p < 0.0001), no college education (adjusted OR = 1.7; 95% CI = 1.2–2.6; p = 0.009), and no daily vigorous/moderate activity (adjusted OR = 1.5; 95% CI = 0.9–2.3; p = 0.12). Among Qatari nationals, obesity was found to be the main risk factor for DM (unadjusted OR = 3.0; 95% CI = 1.6–5.6; p < 0.0001), followed by no college education (unadjusted OR = 2.7; 95% CI = 1.5–5.1; p = 0.001), while consanguinity did not appear to play a major role in predicting DM (unadjusted OR = 1.5; 95% CI = 0.8–2.8; p = 0

    The study aimed to confirm the presence of historic oyster banks of Qatar and code the biotopes present. The research also collated historical records and scientific publications to create a timeline of fishery activity. The oyster banks where once an extremely productive economic resource however, intense overfishing, extreme environmental conditions and anthropogenic impacts caused a fishery collapse. The timeline highlighted the vulnerability of ecosystem engineering bivalves if overexploited. The current status of the oyster banks meant only one site could be described as oyster dominant. This was unexpected as the sites were located in areas which once supported a highly productive oyster fishery. The research revealed the devastating effect that anthropogenic impacts can have on a relatively robust marine habitat like an oyster bed and it is hoped these findings will act as a driver to investigate and map other vulnerable habitats within the region before they too become compromised.

    Background: The Middle East region is predicted to have one of the highest prevalence of diabetes mellitus (DM) in the world. The risk of diabetes continues to increase worldwide and its public health burden is unevenly distributed across socioeconomic strata. This burden is not only related to health care costs, but also to indirect costs caused by loss of productivity from disability and premature mortality. Aim: This study aims to estimate the economics cost of type 2 Diabetes Mellitus [T2DM] among adults in Qatar using national data, and to quantify the potential effect of a suggested preventive intervention program. Design: It is an observational cohort study. Setting: The survey was based on registry at the Hamad General Hospital and Primary Health Care (PHC) centers in the State of Qatar. Subject: This study consisted of patients above 25 years of age with diagnosed diabetes mellitus registered at Hamad General Hospital and Primary Health Care (PHC) centers during January 2004 to July 2014. Methods: We developed a dynamic model in which actual incidence, prevalence, and life expectancy data are used and alternative assumptions about future trends in these parameters can be incorporated. Linear regression model has been performed to forecast the burden of diabetes in oil-rich country. Results: According to the dynamic model, a 10% increased in the number of diabetic patients in the State of Qatar from 33 610 in 2005 to 122 000 in 2012 (about 1% annually). The annual diabetes incidence rate was higher in women than in men during a period between 2005 to 2015 years. The static model forecasted as 10% increase over 10 years. The relative increase in prevalence of diabetes and number of diabetic people are higher in women than in men (16.6%; 17.5% and 18.4% in men vs. 22.6%; 23.8% and 25.1% in women). Most of the increase in prevalence of diabetes is projected to occur in younger age groups where it is estimated to increase among age groups of 50-59 years and

    Prompted by cases of acute hepatitis in expatriate workers presenting at Alkhor Hospital, Qatar, a limited prospective observational study was conducted from July 2005 to June 2006 to determine the epidemiological and clinical features of patients (predominantly Nepalese) presenting with acute hepatitis. Countrywide during that period samples from 86 Nepalese presenting at different centers were found to be anti-HEV IgG positive and 50 of these were also positive for anti-HEV IgM. Fifty-eight of those Nepalese were seen and treated at Alkhor Hospital and of them 43 were confirmed as cases of acute HEV, being positive for both anti-HEV IgM and IgG. The remaining 15 were diagnosed as probable cases of acute HEV on the basis of clinical and epidemiological similarity. It seems likely that transit in Kathmandu in reportedly unsanitary conditions was the focus of infection. In some of those examined at Alkhor, ultrasound detected a thickened gallbladder wall in 30 of 39 (76.9%) with two cases having clinical acalcular cholecystitis. Higher levels of alanine aminotransferase and aspartate aminotransferase were associated with severe disease and derangement in coagulation. On the available evidence hepatitis E was imported by expatriate workers and it is clear that medical screening of these workers pre- and post-arrival must be improved to prevent further outbreaks. It is also essential that health care workers in Qatar are made aware of this ongoing problem of imported HEV and understand the variable presentation of the condition.

    Background: This study was designed to identify the incidence, injury patterns, and actual medical costs of occupational-related falls in Qatar, in order to provide a reference for establishing fall prevention guidelines and recommendations. Settings and Design: Retrospective database registry review in Level 1 Trauma Center at Tertiary Hospital in Qatar. Materials and Methods: During a 12-month period between November 1st 2007 and October 31st 2008, construction workers who fell from height were enrolled. A database was designed to characterize demographics, injury severity score (ISS), total hospital length of stay, resource utilization, and cost of care. Statistical Analysis: Data were presented as proportions, mean ± standard deviation or median and range as appropriate. In addition, case fatality rate and cost analysis were obtained from the Biostatistics and finance departments of the same hospital. Results: There were 315 fall-related injuries, of which 298 were workplace related. The majority (97%) were male immigrants with mean age of 33 ± 11 years. The most common injuries were to the spine, head, and chest. Mean ISS was 16.4 ± 10. There was total of 29 deaths (17 pre-hospital and 12 in-hospital deaths) for a case fatality rate of 8.6%. Mean cost of care (rounded figures) included pre-hospital services Emergency Medical Services (EMS), trauma resuscitation room, radiology and imaging, operating room, intensive care unit care, hospital ward care, rehabilitation services, and total cost (123, 82, 105, 130, 496, 3048,434, and 4418 thousand United States Dollars (USD), respectively). Mean cost of care per admitted patient was approximately 16,000 USD. Conclusions: Falling from height at a construction site is a common cause of trauma that poses a significant financial burden on the health care system. Injury prevention efforts are warranted along with strict regulation and enforcement of occupational laws. PMID:23724377

    Aims: Qatar-1b is a close-orbiting hot Jupiter (Rp ≃ 1.18 RJ, Mp ≃ 1.33 MJ) around a metal-rich K-dwarf, with orbital separation and period of 0.023 AU and 1.42 days. We have observed the secondary eclipse of this exoplanet in the Ks band with the objective of deriving a brightness temperature for the planet and providing further constraints to the orbital configuration of the system. Methods: We obtained near-infrared photometric data from the ground by using the OMEGA2000 instrument at the 3.5 m telescope at Calar Alto (Spain) in staring mode, with the telescope defocused. We have used principal component analysis (PCA) to identify correlated systematic trends in the data. A Markov chain Monte Carlo analysis was performed to model the correlated systematics and fit for the secondary eclipse of Qatar-1b using a previously developed occultation model. We adopted the prayer bead method to assess the effect of red noise on the derived parameters. Results: We measured a secondary eclipse depth of 0.196%+ 0.071%-0.051%, which indicates a brightness temperature in the Ks band for the planet of 1885+ 212-168 K. We also measured a small deviation in the central phase of the secondary eclipse of -0.0079+ 0.0162-0.0043, which leads to a value for ecosω of -0.0123+ 0.0252-0.0067. However, this last result needs to be confirmed with more data.

    Tinea capitis (TC) is a contagious infection that affects mainly children and teenagers. A retrospective study was realized at the mycology-parasitology department of the Ibn Sina hospital in Rabat, Morocco. The study includes 125 cases of TC. The mean age is 12.73 ± 11.61 year. The isolation of TC is dominated by two species Trichophyton violaceum 76 (60.8%) and Microsporum canis 27 (21.6%). Trichophyton verrucosum was isolated only in male and all of rural origin. In adults over 18 years, the most isolated species is T. violaceum (six cases) in females. For the last thirty years, the epidemiological profile of TC remains almost the same in Morocco.

    The Atlantic Ocean, Straits of Gibraltar, and Alboran Sea (the westernmost portion of the Mediterranean Sea) separate Spain on the left from Morocco on the right. Algeciras Harbor is the prominent notch cut out of the eastern end of the north shore of the Strait; the Rock of Gibraltar is the tiny arrowhead that separates the notch from the Alboran Sea. The Sierra Nevada, farther away down the Spanish coast, lives up to its name in this April scene. The difference in elevation between the Sierra Morena and the Guadalquivir River valley is highlighted nicely by cumulus clouds. Tangier, Morocco can be seen as a light-toned spot on the southern shore of the Strait, near the entrance to the Atlantic Ocean.

    Morocco's health system remains weak in spite of the improvement of other development indicators in the last ten years. Health remains one of the major challenges to lower the social disparities that are the priority for the authorities. Despite the goodwill of all stakeholders, significant reforms implemented respond only partially to the needs of the population. Morocco established several public insurance schemes, of which one focuses on the poorest, to achieve financial-risk protection for its population. Nevertheless, achieving universal health coverage through one of its dimensions is not sufficient, and all the effort being concentrated in one area has shown the deterioration of equity in access to and quality of health services. Moreover, the insurance schemes did not reach their objectives of protecting a majority of Moroccans from financial hardship. PMID:26405489

    Consistent constraints of an over-thickened crust beneath the Rif Cordillera (N. Morocco) are inferred from analyses of recently acquired seismic datasets including controlled source wide-angle reflections and receiver functions from teleseismic events. Offline arrivals of Moho-reflected phases recorded in RIFSIS project provide estimations of the crustal thicknesses in 3D. Additional constraints on the onshore-offshore transition are inferred from shots in a coeval experiment in the Alboran Sea recorded at land stations in northern Morocco. A regional crustal thickness map is computed from all these results. In parallel, we use natural seismicity data collected throughout TopoIberia and PICASSO experiments, and from a new RIFSIS deployment, to obtain receiver functions and explore the crustal thickness variations with a H-κ grid-search approach. This larger dataset provides better resolution constraints and reveals a number of abrupt crustal changes. A gridded surface is built up by interpolating the Moho depths inferred for each seismic station, then compared with the map from controlled source experiments. A remarkably consistent image is observed in both maps, derived from completely independent data and methods. Both approaches document a large crustal root, exceeding 50 km depth in the central part of the Rif, in contrast with the rather small topographic elevations. This large crustal thickness, consistent with the available Bouguer anomaly data, favors models proposing that the high velocity slab imaged by seismic tomography beneath the Alboran Sea is still attached to the lithosphere beneath the Rif, hence pulling down the lithosphere and thickening the crust. The thickened area corresponds to a quiet seismic zone located between the western Morocco arcuate seismic zone, the deep seismicity area beneath western Alboran Sea and the superficial seismicity in Alhoceima area. Therefore, the presence of a crustal root seems to play also a major role in the

    Poisonous stings caused by scorpion constitute a public health problem in Morocco because of their frequency severity and socio-economic consequences that they generate. The province of Khouribga surveyed for this study is situated in a zone of high incidence and high lethality caused by scorpion stings in Morocco. In order to analyze the epidemiological profile and the poisoning risk factors, we are presenting the results of a past study conducted from April to December 2001. It consisted in making an exhaustive follow up from admission to release of all patients stung by scorpion. These patients consulted a sanitary structure (dispensary health centre or hospital) in the province of Khouribga, Morocco. Within a total of 1212 cases of stings, 63% of them occurred at night (between 06 pm and 06 am) particularly during July and August. Youngsters under fifteen represented 36% of these cases. 3.4% of the people who got stung presented typical poisoning and envenomation. The delay expected from sting to transfer to a medical structure was 1.85 +/- 0.11 hours for the patients who recovered against 2.67 +/- 0.11 for those who did not recover. To be noticed as well that 1.3% of the subjects who got stung die. Variance analysis indicates that the type of sanitary structures receiving patients, admission classes, and age of patients influence significantly the recovery rate of people who are stung.

    Kidney transplantation is still underdeveloped in Morocco. In order to anticipate needs and discuss a possible reorganization of the provision of care, an estimate of the number of patients who would benefit from kidney transplant was conducted. This study was done in two steps. During the first step, based on the French renal replacement therapy registry (Rein), we develop a prediction score based on the likelihood of being treated by an autonomous dialysis (hemodialysis in self-care unit or peritoneal dialysis non-assisted by a nurse) and be registered on the national kidney transplant waiting list. During the second step, we apply this score to the data of the registry Magredial (Moroccan registry of renal replacement therapy, deployed in seven regions). Twelve parameters were related to autonomy and registration on the waiting list. Each of these parameters has been assigned a weight. Each patient was assigned a number of points, sum of different weights. By retaining a threshold of 21 points (80% specificity), 2260 subjects (57%) had a score less than or equal to this threshold in Magredial. With a number of patients on dialysis in Morocco estimated to 13,000 in late 2013, the estimated need for kidney transplant will be of 7410. This estimate should encourage professionals and health authorities of Morocco to engage more effort in the implementation of actions related to the transplant program.

    Daily mortality rates of female Culicoides imicola were found for eight sites in Morocco in 1994 and for six sites in 1995. The mortality rates were found by operating Pirbright-type light traps for a number of consecutive nights in late summer or autumn and finding the parous rate assuming a feeding interval of 3 to 5 days. The mortality rates were calculated according to established methods. In Morocco the daily mortality rates were found to vary from about 5% per day (Arbaoua, 1994, 1995 and Sidi Moussa 1995) up to 20-25% per day (Berkane, Marrakech, Tangier). In general, estimates of daily mortality rate were consistent between the two years of study. Among sites, daily mortality rate was significantly correlated with the average night-time minimum wind speed but not mean or maximum night-time wind speeds, or with temperature, humidity or saturation deficit. The observed mortality rates suggest that at Arbaoua, were 1,000 flies to become infected with African horse sickness virus, at least 330 would live long enough to take 3 or more infective blood meals on hosts. At Berkane, the survival rate per 1,000 is less than 10. In general, the pattern observed for daily mortality rate, combined with the relative population sizes of C. imicola in Morocco, agree well with the observed distribution of African horse sickness in the country during the 1989-1991 epizootic.

    Background: Although pharmacists have great potential to modify and optimize drug therapy in pregnancy and lactation, current literature demonstrates that they do not routinely provide this care and often feel ill equipped to do so. The objective of this study was to determine pharmacists’ knowledge and perceptions of maternal-fetal medicine in Canada, Uganda and Qatar. Secondary objectives were to determine factors associated with pharmacists’ knowledge and to characterize training opportunities and resources available to practising pharmacists. Methods: A cross-sectional survey using online software (SurveyMonkey) was sent to the e-mails of potential research participants. Practising pharmacists and resident pharmacists in British Columbia, Canada; the country of Qatar; and the country of Uganda were eligible for inclusion. The survey was designed to assess knowledge and perceptions, and to create a baseline inventory of current practice and information resources used in practice. Results: The mean knowledge assessment scores of pharmacists in Canada, Qatar and Uganda were 62.9%, 53.3%, and 57.7%, respectively (p < 0.05). Pharmacists in British Columbia scored higher on knowledge assessment than pharmacists in Qatar (p < 0.05), but other country comparisons were not significant. No predefined factors (gender, years of experience, practice area or parental status) were found to be significant in determining the knowledge score. More than two-thirds of pharmacists expressed interest in participating in continuing education opportunities in maternal-fetal medicine. Conclusion: Pharmacists have differing levels of knowledge in the area of maternal-fetal medicine. Continuing education and degree curricula should be reviewed and developed to fill the knowledge gaps of student pharmacists and practising pharmacists in maternal-fetal medicine. PMID:25364351

    Qatar is a rapidly developing country in which expatriate workers constitute the majority of population. Also, Qatar is an example of right-sided road driving convention (RDC) country. The aim of our study is to analyse the traffic-related pedestrian injuries (TRPI) amongst expatriates in relation to RDC. A retrospective analysis of prospectively collected data of TRPI patients who were admitted to the only Level I trauma centre in Qatar between 2009 and 2011 was performed. Demographics, country of origin, time of injury, injury severity score (ISS), RDC, morbidity and mortality were analysed. Of the 4997 injured patients, 601 (12%) were pedestrians. Of these, 92% were expatriates. The mean age was 31.8 ± 17 and 64% of them were 18-45 years old. Mean ISS was higher in those who were injured on weekends (15.4 ± 10) in comparison to working days (13.5 ± 10) (p = 0.04). The overall mortality was 15%. Sixty-seven percent of those who died were from left RDC countries. Expatriate workers, originally from left RDC countries are disproportionately affected by TRPI. This group of injured patients requires focused injury prevention programmes that are culture and language appropriate.

    In 1985, Glynn et al. [Journal of Medical Virology 17:371-375] reported on epidemic viral hepatitis in Qatar and concluded that 72% (91/126) had acute enterically transmitted non-A, non-B viral hepatitis (ET-NANBH). Most of the patients (98%) presented within 8 weeks of arrival in Qatar and were migrant workers from the Indian subcontinent. The data was reanalysed for evidence of infection with hepatitis E virus (HEV). Seventy-eight of 91 (86%) of stored sera were still suitable for analysis since collection in 1981. A newly described enzyme immunoassay (EIA) for both IgG and IgM anti-HEV was used (Abbott Laboratories, Delkenheim, Germany); 59/78 (76%) were positive for either or both assays. All but two were from the Indian subcontinent. The data suggest that HEV was the major cause of ET-NANBH in Qatar in 1981, particularly among newly arrived migrant workers from the Indian subcontinent.

    The development of the Qatar National Historic Environment Record (QNHER) by the Qatar Museums Authority and the University of Birmingham in 2008 was based on a customised, bilingual Access database and ArcGIS. While both platforms are stable and well supported, neither was designed for the documentation and retrieval of cultural heritage data. As a result it was decided to develop a custom application using Open Source code. The core module of this application is now completed and is orientated towards the storage and retrieval of geospatial heritage data for the curation of heritage assets. Based on MIDAS Heritage data standards and regionally relevant thesauri, it is a truly bilingual system. Significant attention has been paid to the user interface, which is userfriendly and intuitive. Based on a suite of web services and accessed through a web browser, the system makes full use of internet resources such as Google Maps and Bing Maps. The application avoids long term vendor ''tie-ins'' and as a fully integrated data management system, is now an important tool for both cultural resource managers and heritage researchers in Qatar.

    With interest in establishing baseline concentrations of 137Cs in soil from the Qatarian peninsula, we focus on determination of the activity concentrations in 129 soil samples collected across the State of Qatar prior to the 2011 Fukushima Dai-ichi nuclear power plant accident. As such, the data provides the basis of a reference map for the detection of releases of this fission product. The activity concentrations were measured via high-resolution gamma-ray spectrometry using a hyper-pure germanium detector enclosed in a copper-lined passive lead shield that was situated in a low-background environment. The activity concentrations ranged from 0.21 to 15.41 Bq/kg, with a median value of 1 Bq/kg, the greatest activity concentration being observed in a sample obtained from northern Qatar. Although it cannot be confirmed, it is expected that this contamination is mainly due to releases from the Chernobyl accident of 26 April 1986, there being a lack of data from Qatar before the accident. The values are typically within but are sometimes lower than the range indicated by data from other countries in the region. The lower values than those of others is suggested to be due to variation in soil characteristics as well as metrological factors at the time of deposition.

    The expanding economy of Qatar in the last two decades has attracted immigrants, often from countries with poor socio-economic levels. Many arrive with patent intestinal parasitic infections, and recent analyses have indicated consistently rising trends in the prevalence of some infections. Here, we examined 18,563 hospital records of subjects in Qatar seeking medical assistance for a variety of ailments, combining data from 2009 to 2011 with the earlier dataset from 2005 to 2008 to enable trends to be identified across a 7-year period. We found that 8.6% were infected with one or more species of parasites, however in contrast to the earlier period (2005–2008), in the latter 3 years there were falling trends of prevalence providing some optimism that parasitic infections among the resident immigrants have begun to decline. We identified also geographic regions from which resident workers still maintain a relatively high prevalence of helminth infections despite their long-term residence in Qatar. PMID:23478576

    The climate of the State of Qatar and the adjacent region is dominated by subtropical dry, hot desert climate with low annual rainfall, very high temperatures in summer and a big difference between maximum and minimum temperatures, especially in the inland areas. The coastal areas are influenced by the Arabian Gulf, and have lower maximum, but higher minimum temperatures and a higher moisture percentage in the air. The global warming can have profound impact on the mean climate as well as extreme weather events over the Arabian Peninsula that may affect both natural and human systems significantly. Therefore, it is important to assess the future changes in the seasonal/annual mean of temperature and precipitation and also the extremes in temperature and wind events for a country like Qatar. This study assesses the performance of the Coupled Model Inter comparison Project Phase 5 (CMIP5) simulations in present and develops future climate scenarios. The changes in climate extremes are assessed for three future periods 2016-2035, 2046-2065 and 2080-2099 with respect to 1986-2005 (base line) under two RCPs (Representative Concentrate Pathways) - RCP4.5 and RCP8.5. We analyzed the projected changes in temperature and precipitation extremes using several indices including those that capture heat stress. The observations show an increase in warm extremes over many parts in this region that are generally well captured by the models. The results indicate a significant change in frequency and intensity of both temperature and precipitation extremes over many parts of this region which may have serious implications on human health, water resources and the onshore/offshore infrastructure in this region. Data from a high-resolution (20km) AGCM simulation from Meteorological Research Institute of Japan Meteorological Agency for the present (1979-2003) and a future time slice (2075-2099) corresponding to RCP8.5 have also been utilized to assess the impact of climate change on

    Objective: To determine the prevalence of eclampsia in Qatar, the associated maternal and perinatal outcomes for the period from January 1991 to December 2009 and to define any possible preventive measures to this potentially fatal complication. Methods: A retrospective case review was performed of all women with eclampsia admitted to the Women's Hospital and Obstetrics and Gynecology department at Al Khor Hospital for the period from January 1991 to December 2009. Details were collected by reviewing the files of the patients from the medical records. Data were analyzed by either X2 analysis or the unpaired student “t” test as appropriate. Results: During the period of the study there were 224,809 births. Seventy women developed eclampsia (0.31/1000 deliveries), 44.3% of them were antepartum, 31.4% postpartum and 24.3% intrapartum eclampsia. 34.3% of patients presented with fits, 38.5% presented with pre-eclampsia (PE) and 20% presented with severe pre eclampsia; 18.5% were mild PE and another 27.2% were admitted with different complaints. Symptoms of impending eclampsia were seen in 22.9% of the PE patients. Thirty percent had no antenatal care (ANC). Antihypertensive therapy was given to 72% of cases. Antiepileptic therapy was administered to 48% of cases and 58.5% received magnesium sulfate. Eclampsia was associated with increased rate of cesarean section (CS) (64.2%). There was one maternal death, and the rate of major maternal complications was 20%. The perinatal mortality rate was 12.8%. Conclusion: The incidence of eclampsia in Qatar is 0.31 per 1000 deliveries. Although rare, this condition is associated with increased maternal morbidity and perinatal mortality. However our result is lower than reported worldwide. Improvement of obstetric care by having high index of suspicion even with apparently low risk patients, using magnesium sulfate prophylaxis for all cases of severe pre-eclampsia, in addition to community based approach to improve community

    Bovine tuberculosis (BTB) is an endemic zoonosis in Morocco caused by Mycobacterium bovis, which infects many domestic animals and is transmitted to humans through consumption of raw milk or from contact with infected animals. The prevalence of BTB in Moroccan cattle is estimated at 18%, and 33% at the individual and the herd level respectively, but the human M. bovis burden needs further clarification. The current control strategy based on test and slaughter should be improved through local context adaptation taking into account a suitable compensation in order to reduce BTB prevalence in Morocco and decrease the disease burden in humans and animals. We established a simple compartmental deterministic mathematical model for BTB transmission in cattle and humans to provide a general understanding of BTB, in particular regarding transmission to humans. Differential equations were used to model the different pathways between the compartments for cattle and humans. Scenarios of test and slaughter were simulated to determine the effects of varying the proportion of tested animals (p) on the time to elimination of BTB (individual animal prevalence of less than one in a thousand) in cattle and humans. The time to freedom from disease ranged from 75 years for p = 20% to 12 years for p = 100%. For p > 60% the time to elimination was less than 20 years. The cumulated cost was largely stable: for p values higher than 40%, cost ranged from 1.47 to 1.60 billion euros with a time frame of 12 to 32 years to reach freedom from disease. The model simulations also suggest that using a 2mm cut off instead of a 4mm cut off in the Single Intradermal Comparative Cervical Tuberculin skin test (SICCT) would result in cheaper and quicker elimination programs. This analysis informs Moroccan bovine tuberculosis control policy regarding time frame, range of cost and levels of intervention. However, further research is needed to clarify the national human-bovine tuberculosis ratio in Morocco

    Northwestern Morocco is undergoing a sudden change in the level of infrastructure growth and pressure on the environment from increased tourism. The ongoing changes are raising questions about how the ecosystem will react, and the relevant drivers of these changes. The Oued Laou valley in north-west Morocco hosts high landscape, species and human cultural diversity. The Talassemtane National Park has been established to preserve the environment in this region; however, what information tools are available to children regarding this environment? The ecosystem is illustrated here using three components: herpetofauna (representing ecosystem components), problems related to water quantity and quality (representing interactions within ecosystem components) and Talassemtane National Park (representing a case of ecosystem management). A children's book was written on this topic, and when the book was delivered to pupils, a questionnaire was included, aimed at determining their sources of environmental information. The results identified major changes in the sources of information utilized by children in this part of Morocco, a clear role of schools in explaining ecosystem components, and an increasing role of TV in environmental information supply. The role of the family was found to be less important than TV or school. Another major source of pupils' environmental knowledge is personal observation and hands-on experience, both for rural and urban children. Children are willing to discover and understand complex systems, and researchers should be encouraged to supply children with correct and up-to-date information on environmental systems, focusing at first on the local environment, as a background for sustainable development.

    We have obtained new regional centroid moment tensors (RCMTs) for 35 earthquakes occurred in Morocco and vicinity between 2008 and 2012. During this time period an unprecedented number of broadband stations (more than 100) were operating in the region, providing high-quality waveform data that were used to obtain RCMTs from waveform inversion. The main part of this dataset was composed of temporary broadband stations that were concurrently deployed in different seismic experiments (i.e. IberArray, PICASSO, Muenster, Bristol). The events analyzed in this study are moderate in size, ranging in moment magnitude Mw from 3.5 to 4.8. Their predominant mechanisms correspond to reverse and strike-slip faulting, although normal and "mixed" mechanisms are also observed. In spite of this variability in mechanism type, when analyzed in terms of the orientation of the P (compression) axes two major groups can be distinguished. The first group, corresponding to earthquakes in the Altas and NE Morocco is characterized by near-horizontal P axes oriented in an approximately NW-SE direction that coincides with the direction of convergence between Africa and Eurasia. A small clockwise rotation of the orientation of the P axes is observed from eastern Morocco to the western Atlas. The second group corresponds to earthquakes in the western Rif, that are characterized also by horizontal P axes, but oriented in a SW-NE direction, almost perpendicular to the first group. These earthquakes are part of a cluster located north of Ouezzane. The mechanisms in this second cluster are consistent with recent GPS results that show that the western Rif is moving in a SW direction with respect to the African (Nubia) plate.

    CDC is working closely with the World Health Organization (WHO) and other partners to better understand the public health risk presented by a recently detected, novel coronavirus. This virus has been identified in two patients, both previously healthy adults who suffered severe respiratory illness. The first patient, a man aged 60 years from Saudi Arabia, was hospitalized in June 2012 and died; the second patient, a man aged 49 years from Qatar with onset of symptoms in September 2012 was transported to the United Kingdom for intensive care. He remains hospitalized on life support with both pulmonary and renal failure. Person-to-person or health-care-associated transmission has not been identified to date. Interim case definitions based on acute respiratory illness and travel history were issued by WHO on September 29 and include criteria for "patient under investigation," "probable case," and "confirmed case". This information is current as of October 4. Updates on the investigation and the WHO case definition are available at http://www.who.int/csr/don/en/index.html.

    The effect of weather on sport events is not well studied. It requires special attention if the event is taking place at a time and place with extreme weather situations. For the world soccer championship in Qatar (Doha 2022), human biometeorological analysis has been performed in order to identify the time of the year that is most suitable in terms of thermal comfort for visitors attending the event. The analysis is based on thermal indices like Physiologically Equivalent Temperature (PET). The results show that this kind of event may be not appropriate for visitors, if it is placed during months with extreme conditions. For Doha, this is the period from May to September, when conditions during a large majority of hours of the day cause strong heat stress for the visitors. A more appropriate time would be the months November to February, when thermally comfortable conditions are much more frequent. The methods applied here can quantify the thermal conditions and show limitations and possibilities for specific events and locations.

    Despite their wealth and modern road systems, traffic injury rates in Middle Eastern countries are generally higher than those in Western countries. The authors examined traffic injuries in Qatar during 2000-2010, a period of rapid population growth, focusing on the impact of speed control cameras installed in 2007 on overall injury rates and mortality. During the period 2000-2006, prior to camera installation, the mean (SD) vehicular injury death rate per 100,000 was 19.9±4.1. From 2007 to 2010, the mean (SD) vehicular death rates were significantly lower: 14.7±1.5 (p=0.028). Non-fatal severe injury rates also declined, but mild injury rates increased, perhaps because of increased traffic congestion and improved notification. It is possible that speed cameras decreased speeding enough to affect the death rate, without affecting overall injury rates. These data suggest that in a rapidly growing Middle Eastern country, photo enforcement (speed) cameras can be an important component of traffic control, but other measures will be required for maximum impact.

    Exome sequencing of families of related individuals has been highly successful in identifying genetic polymorphisms responsible for Mendelian disorders. Here, we demonstrate the value of the reverse approach, where we use exome sequencing of a sample of unrelated individuals to analyze allele frequencies of known causal mutations for Mendelian diseases. We sequenced the exomes of 100 individuals representing the three major genetic subgroups of the Qatari population (Q1 Bedouin, Q2 Persian-South Asian, Q3 African) and identified 37 variants in 33 genes with effects on 36 clinically significant Mendelian diseases. These include variants not present in 1000 Genomes and variants at high frequency when compared to 1000 Genomes populations. Several of these Mendelian variants were only segregating in one Qatari subpopulation, where the observed subpopulation specificity trends were confirmed in an independent population of 386 Qataris. Pre-marital genetic screening in Qatar tests for only 4 out of the 37, such that this study provides a set of Mendelian disease variants with potential impact on the epidemiological profile of the population that could be incorporated into the testing program if further experimental and clinical characterization confirms high penetrance.

    There has been little research into the effectiveness of primary-care diabetes clinics in the Middle East. This study in Qatar compared patient outcomes at a primary-care facility with a dedicated diabetes clinic and one without. Using a cross-sectional method, data on demographics, diabetes status and 6 clinical outcomes of diabetes care were collected from the records of patients who visited the clinics during 2012. Diabetes management in both facilities improved clinical outcomes over the 1-year observation period. The mean total cholesterol of patients attending the special clinic (n = 102) decreased significantly from 4.66 to 4.27 mmol/dL and LDL cholesterol from 3.42 to 3.22 mmol/dL. The LDL cholesterol of patients receiving standard care (n = 108) reduced significantly from 3.41 to 3.22 mmol/dL and HDL cholesterol increased from 0.83 to 0.87 mmol/dL. Inter-provider comparisons indicated that the outcomes in the facility with a diabetes clinic were not superior to those in the facility with standard care.

    Contagious caprine pleuropneumonia (CCPP) caused by Mycoplasma capricolum subsp. capripneumoniae is a highly contagious and serious respiratory disease of domestic goats, characterized by coughing, severe respiratory distress, and high mortality rates. The lesions at necropsy are mainly a fibrinous pleuropneumonia with increased straw-colored pleural fluid. An outbreak of CCPP in wild goat (Capra aegagrus), Nubian ibex (Capra ibex nubiana), Laristan mouflon (Ovis orientalis laristanica), and gerenuk (Litocranius walleri) occurred at Al Wabra Wildlife Preservation in the State of Qatar. The disease was suspected because of the clinical symptoms and the necropsy findings and was confirmed by the isolation and identification of the causative organism. This new finding indicates that CCPP should be considered a potential threat to wildlife and the conservation of endangered ruminant species, especially in the Middle East, where it is enzootic because of its presence in chronic carriers. Susceptible imported animals should be quarantined and vaccinated. The preferred samples for diagnosis are the pleural fluid, which contains high numbers of Mycoplasma, and sections of hepatized lung, preferably at the interface of normal and diseased tissues. Samples must be shipped to diagnostic laboratories rapidly, and appropriate cool conditions must be maintained during shipping.

    The water supply of many countries in the Middle East relies mainly on water desalination. In Qatar, the water network is completely fed with water from desalination plants. One of these power and desalination plants is located in Ras Abu Fontas, 20 km south of the capital Doha. The heat required for thermal desalination is provided by steam which is generated in waste heat recovery boilers (HRB) connected to gas turbines. Additionally, gas fired boilers or auxiliary firing in the HRBs are used in order to decouple the water generation from the electricity generation. In Ras Abu Fontas some auxiliary boilers run 24/7 because the HRB capacity does not match the demand of the desalination units. This paper contains the techno-economic analysis of two large-scale commercial solar field options, which could reduce the fuel consumption significantly. Both options employ parabolic trough technology with a nominal saturated steam output of 350 t/h at 15 bar (198°C, 240 MW). The first option uses direct steam generation without storage while the second relies on common thermal oil in combination with a molten salt thermal storage with 6 hours full-load capacity. The economic benefit of the integration of solar power depends mainly on the cost of the fossil alternative, and thus the price (respectively opportunity costs) of natural gas. At a natural gas price of 8 US-/MMBtu the internal rate of return on equity (IRR) is expected at about 5%.

    Objectives: The purpose of this study was to investigate the physicians’ perceptions, and expectations of their experiences with the pharmacists at Hamad Medical Corporation (HMC) in Qatar. Method: A cross-sectional study was conducted at HMC between January and March 2006 using a validated questionnaire. The self-administered questionnaire was distributed to 500 physicians who were working at HMC comprising Hamad General Hospital, Women’s Hospital, Rumaila Hospital, Al-Amal Hospital, Al Khor Hospital, and primary health centers. The questionnaire was composed of four parts, investigating the physicians’ expectations, experiences, and perceptions of the pharmacists. Results: A total of 205 questionnaires were completed (response rate 41%). A total of 183 physicians (89%) expected the pharmacist to educate patients about safe and appropriate use of drugs, whereas 118 (57%) expected the pharmacist to be available for health-care team consultation during bedside rounds. The indices of physicians showing how comfortable they were with pharmacists, and their expectations of pharmacists, were 61% and 65%, respectively, whereas the index on experience of physicians with pharmacists was lower (15%). Conclusions: Physicians were comfortable with pharmacists and had high expectations of pharmacists in performing their duties. However, physicians reported a poor experience with pharmacists, who infrequently informed them about the effectiveness of alternative drugs, patients experiencing problems with prescribed medications, and who took personal responsibility to resolve any drug-related problem.

    Curating boats can be difficult. They are complex structures, often demanding to conserve whether in or out of the water; they are usually large, difficult to move on land, and demanding of gallery space. Communicating life on board to a visiting public in the terra firma context of a museum can be difficult. Boats in their native environment are inherently dynamic artifacts. In a museum they can be static and divorced from the maritime context that might inspire engagement. New technologies offer new approaches to these problems. 3D laser scanning and digital modeling offers museums a multifaceted means of recording, monitoring, studying and communicating watercraft in their care. In this paper we describe the application of 3D laser scanning and subsequent digital modeling. Laser scans were further developed using computer-generated imagery (CGI) modeling techniques to produce photorealistic 3D digital models for development into interactive, media-based museum displays. The scans were also used to generate 2D naval lines and orthographic drawings as a lasting curatorial record of the dhows held by the National Museum of Qatar.

    The objective of the study was to determine the effects of tobacco use on selected markers of health and lung function in professional athletes. A total of 108 male professional athletes participated in the study from ten ball game teams in the same sport league in Qatar (age = 26.4 ± 5.1 yrs, height = 190.6 ± 11.9 cm, and weight = 91.5 ± 16.4 kg). The athletes have been playing professionally for about 6.3 years on average. In addition to demographic and tobacco use status, the following clinical variables were measured: resting blood pressure, heart rate, FVC, FEV1 sec, and PEF. The prevalence of tobacco use among the athletes was 27.7%. The FVC, FVC%, and FEV1% were significantly lower among the smokers compared to the nonsmokers (p = 0.003, 0.044, and 0.001, resp.). There were no significant differences between cigarettes smokers and nonsmokers in BP, HR, FEV1, FEV1/FVC, PEF, and PEF%. Similarly, those who smoked shisha had lower FEV1% values as compared to those who did not smoke shisha (p = 0.001). The decrease of FEV1 and FVC among smokers compared to nonsmokers is similar to what has been reported in the literature about other populations. PMID:28025593

    Objective: To evaluate Qatari pharmacists’ prescribing, labeling, dispensing and counseling practices in response to acute community-acquired gastroenteritis. Methods: The simulated patient method was used in this study. Thirty pharmacies in Doha were randomly selected and further randomized into two groups: Face-to-Face (n=15) vs. Telephone-call (n=15) per simulated patient; 2 simulated patients were involved. Prescribing, labeling, dispensing and counseling practices were assessed. Data analysis was performed using Mann-Whitney and chi square tests at alpha=0.05. Results: Most pharmacists prescribed and dispensed medicines (96%), including antimicrobials (43.9%), antidiarrheals (36%), antiemetics (5.1%) and antipyretics (3%). Counseling practices were poor (62.1% in the face-to-face group vs 70% in the telephone-call group did not counsel simulated patients about the dispensed medicines; p-value=0.50). In more than one-third of the encounters, at least one labeling parameter was missing. The duration of each interaction in minutes was not significantly different between the groups [median (IQR); 3(4.25) in the face-to-face group versus 2(0.25) in the telephone-call group; p-value=0.77]. No significant differences in prescribing or dispensing behaviors were present between groups (p-value>0.05). Conclusion: Qatar community pharmacists’ labeling, dispensing, and counseling practices were below expectation, thus urging the need for continuous professional development. PMID:28042351

    In Morocco, the seroprevalence of toxoplasmosis in pregnant women living in Rabat, was estimated by analyzing antibodies (IgG, IgM) levels using an ELISA test. The analysis of 2456 serums at the Institut National d'Hygiène showed that the seroprevalence of toxoplasmosis is about 50.6%. According to the questionnaire, the lack of knowledge about this disease and soil contact could be the main causes of toxoplasmosis infection. The use of IgG avidity test has excluded a recent infection in 93.5% of pregnant women with IgM positive sera.

    Leishmania infantum (Kinetoplastida: Trypanosomatidae) infection is transmitted by an infected female sand fly (Diptera: Psychodidae, Phlebotominae) of the subgenus Larroussius: Phlebotomus ariasi, Phlebotomus perniciosus, and Phlebotomus longicuspis in the Mediterranean basin. In Morocco, the vectorial role of P. ariasi was demonstrated, while that of P. longicuspis and P. perniciosus is not elucidated. In addition, Moroccan P. longicuspis and P. perniciosus populations present a higher morphologic and genetic variability. It was classified as P. perniciosus complex, including typical (PN) and atypical (PNA) morphs of P. perniciosus, P. longicuspis sensu stricto (LCss), and a sibling species of P. longicuspis (LCx). With the aim to study the ecological and epidemiological status of P. perniciosus complex species in Morocco, entomological surveys were carried out during three entomological seasons (2012, 2013, and 2014). We collected a total of 6298 specimens from 81 localities of northern, central, and southern Morocco. After describing the geographical distribution of P. perniciosus complex trough Morocco according to many variables (altitude, latitude, and longitude), we discuss the resulting epidemiological implications of its species. Our results highlight the geographical distribution of the two morphs of P. perniciosus through Morocco: PN is limited to the north, while PNA is widespread in northern, central, and southern Morocco. In terms of vectorial role, we hypothesize the potential involvement of PN, LCss, and LCx, at least, with P. ariasi, in the epidemiological cycle of L. infantum in Morocco.

The samples (sea water, plankton, shellfish and sediment) were collected fortnightly for two years from three study sites on the coast Tamouda Bay in northern Morocco. The charge of Vibrio alginolyticus is determined by MPN method. The physicochemical parameters including temperature of sea water, pH, salinity, turbidity and chlorophyll a concentration were determined. Analysis of variance of specific variables and several principal component analyses showed that the temperature of seawater is the major determinant of seasonal distribution of Vibrio alginolyticus. The results showed a positive linear correlation between Vibrio alginolyticus and the water temperature, pH, turbidity and chlorophyll a. Similarly, there are seasonal variations and spatial of Vibrio alginolyticus in marine environment of the Tamouda bay and the highest concentrations were recorded in both years of study during the warm season whereas it was minimal during the cold season. Linear positive correlation was recorded between Vibrio alginolyticus populations in all ecological types of samples studied.

    Geologic, geophysical and remote sensing evidence shows that the Paleozoic basement of Morocco is fragmented at various scales. Wrench faults, difficult to identify by conventional methods were examined from a regional perspective and through careful observation and assessment of many factors. Subsurface structural mapping and geoseismic cross-sections supported by outcrop studies and geomorphological features revealed a network of strike slip faults. Although controversy still surrounds interpretation of major faults as wrench type, with various amounts of strike-slip, or as reverse dip-slip with large amount of shortening, mapping of these basement fault block pattern in Moroccan sedimentary basins revealed literally many correlations of these blocks with prospective structures. These range from simple fault traps, to horst blocks, to fracture systems, to asymmetrical folds over reverse faults. Additionally, many types of stratigraphic traps correlate with basement shear zones. One example is the Middle Devonian algal mounds complex in the Doukkala Basin that evidently formed on fault scarps and/or fault-caused sea floor highs. The present study demonstrates that most of defined prospective structures in Morocco result from basement fault control and considers precise mapping of these pattern a pervasive and prerequisite exploration approach to go forward in upcoming exploration programs.

    In order to select the main medicinal plants used in folk medicine to treat arterial hypertension and/or diabetes, a survey was undertaken in different areas of oriental Morocco. The patients (370 women and 256 men) were divided into three groups: diabetics (61%), hypertensives (23%) and hypertensive diabetic persons (16%). On average, 67.51% of patients regularly use medicinal plants. This proportion is perceptibly the same in all groups and does not depend on sex, age and socio-cultural level. This result shows that phytotherapy is widely adopted in northeastern Morocco. For diabetes, 41 plants were cited, of which the most used were Trigonella foenum-graecum L. (Leguminosae), Globularia alypum L. (Globulariaceae), Artemisia herba-alba Asso. (Compositae), Citrullus colocynthis (L.) Schrad. (Cucurbitaceae) and Tetraclinis articulata Benth. (Cupressaceae). In the hypertension's therapy 18 vegetal species were reported, of which the most used were Allium sativum L. (Liliaceae), Olea europea L. (Oleaceae), Arbutus unedo L. (Ericaceae), Urtica dioica L. (Urticaceae) and Petroselinum crispum A.W. Hill (Apiaceae). Among the 18 species used for hypertension, 14 were also employed for diabetes. Moreover, these two diseases were associated in 41% of hypertensives. These findings suggest that hypertension observed in this region would be in a large part related to diabetes.

    The lower Mesozoic half grabens of northern Morocco form part of an extensional system that is related to the opening of the western Tethys. They appear to be somewhat younger than the Triassic-Jurassic systems associated with the opening the Atlantic Ocean. During the Tertiary and as consequence of the Alpine collision of Africa with Europe, these half graben systems were inverted as shown by the High and the Middle Atlas mountains. Seismic illustrations of similar but smaller inversion structures are available from the Guercif area and the [open quotes]Rides Prerifaines[close quotes] of northern Morocco. These seismic profiles serve as small models for the much larger Atlas Mountains. In the Guercif area, the inversions are limited in scope, but in the [open quotes]Ride Prerifaines[close quotes] are extensive decollement systems that sole out in the Triassic evaporites. These systems evolve into complex thrust faults and associated lateral ramps that are strongly influenced by the configuration of the Jurassic transtensional systems. Significant hydrocarbon accumulation have been known for some time from the [open quotes]Rides Prerifaines.[close quotes] A review of the geometry of the inverted half-graben systems, combined with detailed stratigraphic studies, is likely to lead to the discovery of additional reserves in the area.

    Morocco is known to a region of frequent witness of meteorite falls and/or recovery. This dictate the necessity to create the first Moroccan meteor network. This paper presents the results of the 2012 Geminid observation campaign performed at the Atlas Golf Marrakesh, Marrakesh, Morocco. It was found that the Geminids duration is generally correlated to their magnitude. Moreover, we analyse a Geminid spectrum showing a normal class spectrum, with high sodium content. Morocco is found to be an excellent place for meteor observation and future work and collaboration are presented.

  8. Procedures of recruiting, obtaining informed consent, and compensating research participants in Qatar: findings from a qualitative investigation

    Background Very few researchers have reported on procedures of recruiting, obtaining informed consent, and compensating participants in health research in the Arabian Gulf Region. Empirical research can inform the debate about whether to adjust these procedures for culturally diverse settings. Our objective was to delineate procedures related to recruiting, obtaining informed consent, and compensating health research participants in the extremely high-density multicultural setting of Qatar. Methods During a multistage mixed methods project, field observations and qualitative interviews were conducted in a general medicine clinic of a major medical center in Qatar. Participants were chosen based on gender, age, literacy, and preferred language, i.e., Arabic, English, Hindi and Urdu. Qualitative analysis identified themes about recruitment, informed consent, compensation, and other research procedures. Results A total of 153 individuals were approached and 84 enrolled; the latter showed a diverse age range (18 to 75 years); varied language representation: Arabic (n = 24), English (n = 20), Hindi (n = 20), and Urdu (n = 20); and balanced gender distribution: women (n = 43) and men (n = 41). Primary reasons for 30 declinations included concern about interview length and recording. The study achieved a 74% participation rate. Qualitative analytics revealed key themes about hesitation to participate, decisions about participation with family members as well as discussions with them as “incidental research participants”, the informed consent process, privacy and gender rules of the interview environment, reactions to member checking and compensation, and motivation for participating. Vulnerability emerged as a recurring issue throughout the process among a minority of participants. Conclusions This study from Qatar is the first to provide empirical data on recruitment, informed consent, compensation and other research procedures in a general

    Human Papillomavirus (HPV) infections are known to cause cervical cancer worldwide, however, limited information is currently available on prevalence, types distribution and risk factors for HPV infection in the Arab countries. We conducted a cross-sectional observational study exclusively of women of Arabic origin residing in Qatar (n = 406) who were selected from the Women’s Hospital at Hamad Medical Corporation (HMC) and Health Centers of the Primary Health Care Corporation in Doha, Qatar over the period March 2013 to August 2014. Socio-demographic, behavioral and clinical data were collected. Four hundred and six cervical smears and 292 blood samples were included in the study. HPV typing was done using HPV type-specific primers-based real-time PCR, and Sanger sequencing. HPV-IgG and IgM were quantified using ELISA assays. The prevalence of HPV infection amongst Qatari and non-Qatari Arab women were 9.8% and 6.1%, respectively and 7.6% and 16.7% in women with normal and abnormal cytology, respectively. HPV 81 was the most commonly found genotype in women with normal cytology (34.5%), whereas HPV 81, 16 and 59 in women with abnormal cytology (25.0% each). All the HPV DNA positive women were seronegative and HPV-IgG prevalence was higher in Qatari women than in non-Qatari Arab women. None of the studied factors had any significant association with HPV-DNA positivity or HPV-IgG seropositivity. The overall identified HPV DNA prevalence and HPV seroprevalence among Arab women in Qatar were on the low side compared to global levels. PMID:28046025

    We present 17 high-precision light curves of five transits of the planet Qatar-2 b, obtained from four defocused 2 m-class telescopes. Three of the transits were observed simultaneously in the Sloan g'r'i'z' passbands using the seven-beam Gamma Ray Burst Optical and Near-Infrared Detector imager on the MPG/ESO 2.2-m telescope. A fourth was observed simultaneously in Gunn grz using the Centro Astronómico Hispano Alemán 2.2-m telescope with Bonn University Simultaneous Camera, and in r using the Cassini 1.52-m telescope. Every light curve shows small anomalies due to the passage of the planetary shadow over a cool spot on the surface of the host star. We fit the light curves with the PRISM+GEMC model to obtain the photometric parameters of the system and the position, size and contrast of each spot. We use these photometric parameters and published spectroscopic measurements to obtain the physical properties of the system to high precision, finding a larger radius and lower density for both star and planet than previously thought. By tracking the change in position of one star-spot between two transit observations, we measure the orbital obliquity of Qatar-2 b to be λ = 4.3° ± 4.5°, strongly indicating an alignment of the stellar spin with the orbit of the planet. We calculate the rotation period and velocity of the cool host star to be 11.5 ± 0.2 d and 3.28 ± 0.04 km s-1 at a colatitude of 74°. We assemble the planet's transmission spectrum over the 386-976 nm wavelength range and search for variations of the measured radius of Qatar-2 b as a function of wavelength. Our analysis highlights a possible H2/He Rayleigh scattering in the blue.

    Qatar, a narrow peninsula covering an area of 11437 sq km, extends northwards into the Arabian Gulf for about 160km and has a maximum width of 88km. The convex shape of the coast-line and narrowness of the peninsula results in the Qatar region experiencing complex wind patterns. The geometry is favorable for formation of the land-sea breeze from both coastal sides of the peninsula. This can lead to the development of sea breeze convergence zones in the middle of the country. Although circulations arising from diurnal thermal contrast of land and water are amongst most intensively studied meteorological phenomena, there is no reported study for the Qatar peninsula and very few studies are reported for the Arabian Gulf region as whole. It is necessary to characterize the wind field for applications such as assessing air pollution, renewable energy etc. A non-hydrostatic mesoscale model, Weather Research and Forecast (WRF) with a nested high resolution grid permits the investigation of such fine scale phenomena. Data from eighteen land based Automated Weather Stations (AWS) and two offshore buoys deployed and maintained by the Qatar Meteorological Department were analyzed. Based on the analysis a clear case of sea breeze convergence were seen on 18 September 2015. Model simulations were used to investigate the synoptic conditions associated with the formation of this event. The season is characterized by week ambient north westerly wind over the Arabian Gulf. The WRF model performance is validated using observed in-situ data. Model simulations show that vertical extent of sea breeze cell was up to 1 km and the converging sea breeze regions were characterized with high vertical velocities. The WRF simulation also revealed that with high resolution, the model is capable of reproducing the fine scale patterns accurately. The error of predictions in the inner domain (highest resolution) are found to be relatively lower than coarse resolution domain. The maximum wind speed

    2013-01-01

    Background Despite rising breast cancer incidence and mortality rates, breast cancer screening (BCS) rates among women in Qatar remain low. Previous studies indicate the need to better understand the many complex beliefs, values, and attitudes that influence Arab women’s health seeking behavior for the development of culturally appropriate and effective intervention strategies to address breast cancer in the Middle East. This study investigates beliefs, attitudes, and BCS practices of Arabic-speaking women in Qatar. Methods A multicenter, cross-sectional quantitative survey of 1,063 (87.5% response rate) Arabic-speaking female Qatari citizens and non-Qatari residents, 35 years of age or older, was conducted in Qatar from March 2011 to July 2011. Associations between beliefs and BCS practice were estimated using chi-square tests and multivariate logistic regression analyses. Participants who adhered to BCS guidelines (BCS practice = Yes) were compared to those who did not (BCS practice = No). Results In addition to low levels of awareness and low participation rates in BCS, one quarter of the participants stated their doctors talked to them about breast cancer, and less than half of the women interviewed believed breast cancer can be prevented. Women who engaged in BCS practice were more likely to have a doctor who talked to them about breast cancer, to believe they were in good–excellent health, that cancer can be prevented, or that cancer might be hereditary. The majority wanted to know if they had cancer and felt their health care needs were being met. The main reasons given for not planning BCS were lack of a doctor’s recommendation, fear, and embarrassment. Conclusions These findings indicate that a variety of channels (health care providers, media, breast cancer survivors, community leaders) should be utilized to create culturally appropriate breast cancer intervention programs and increased awareness of breast cancer, BCS, and the benefits of

    Background: The use of emergency department (ED) services for non-urgent conditions is well-studied in many Western countries but much less so in the Middle East and Gulf region. While the consequences are universal—a drain on ED resources and poor patient outcomes—the causes and solutions are likely to be region and country specific. Unique social and economic circumstances also create gender-specific motivations for patient attendance. Alleviating demand on ED services requires understanding these circumstances, as past studies have shown. We undertook this study to understand why female patients with low-acuity conditions choose the emergency department in Qatar over other healthcare options. Setting and design: Prospective study at Hamad General Hospital's (HGH) emergency department female “see-and-treat” unit that treats low-acuity cases. One hundred female patients were purposively recruited to participate in the study. Three trained physicians conducted semi-structured interviews with patients over a three-month period after they had been treated and given informed consent. Results: The study found that motivations for ED attendance were systematically influenced by employment status as an expatriate worker. Forty percent of the sample had been directed to the ED by their employers, and the vast majority (89%) of this group cited employer preference as the primary reason for choosing the ED. The interviews revealed that a major obstacle to workers using alternative facilities was the lack of a government-issued health card, which is available to all citizens and residents at a nominal rate. Conclusion: Reducing the number of low-acuity cases in the emergency department at HGH will require interventions aimed at encouraging patients with non-urgent conditions to use alternative healthcare facilities. Potential interventions include policy changes that require employers to either provide workers with a health card or compel employees to acquire one for

    We used a combination of subjective (questionnaire) and objective (urinary metabolites) measurements to evaluate factors that can predict the exposure of farm workers in Qatar to organophosphate pesticides and to assess whether the levels of exposure are associated with any self-reported health outcomes. The results show that pesticides were being extensively mishandled in the farms. Very few (<2%) of the farm workers knew the names of the pesticide they were using, and about one-third of the participants did not know the amount of pesticides to be applied to the crops. Nearly all (96%) of the participants had participated in mixing pesticides together before use and few (29%) used protective clothing while engaged in this operation. A significant number of participants (18%) had no knowledge that pesticides are a health hazard. At least one dialkyllphosphate (DAP) metabolite was detected in every worker. The geometric mean (GM) concentration of the dimethylalkylphosphates (DMAP) was 108 nM (range, from below the limit of detection (LOD) to 351 nM), and the GM for the diethylalkylphosphates (DEAP) was 43 nM (range, LOD-180 nM). The GM for total concentration of the metabolites (DAP) of 146 nM (maximum value estimated to be 531 nM) is below the values that have been reported for farmers in some countries, but higher than the levels in the general populations of many countries. We explored the influence of metal exposure and found consistent and negative relationships between the DAP metabolites and the concentrations of most of the trace elements in the urine of the farm workers; the negative associations were statistically significant for Cr, Mn, Fe, Ni, As, and Pb. We suspect that the negative associations are not source-dependent but may be reflective of antagonistic relationships in human metabolism of OPPs and trace metals; hence we recommend that metals should be included as co-factors in assessing the health effects of OPP exposure.

    The Qatar-2 transiting exoplanet system was recently observed in short-cadence mode by Kepler as part of K2 Campaign 6. We identify dozens of starspot-crossing events, when the planet eclipses a relatively dark region of the stellar photosphere. The observed patterns of these events demonstrate that the planet always transits over the same range of stellar latitudes and, therefore, that the stellar obliquity is less than about 10°. We support this conclusion with two different modeling approaches: one based on explicit identification and timing of the events and the other based on fitting the light curves with a spotted-star model. We refine the transit parameters and measure the stellar rotation period (18.5 ± 1.9 days), which corresponds to a “gyrochronological” age of 1.4 ± 0.3 Gyr. Coherent flux variations with the same period as the transits are well modeled as the combined effects of ellipsoidal light variations (15.4 ± 4.8 ppm) and Doppler boosting (14.6 ± 5.1 ppm). The magnitudes of these effects correspond to a planetary mass of 2.6+/- 0.9 {M}{Jup} and 3.9+/- 1.5 {M}{Jup}, respectively. Both of these independent mass estimates agree with the mass determined by the spectroscopic Doppler technique (2.487+/- 0.086 {M}{Jup}). No occultations are detected, giving a 2σ upper limit of 0.06 on the planet’s visual geometric albedo. We find no evidence for orbital decay, although we are only able to place a weak lower bound on the relevant tidal quality factor: {Q}\\star \\prime > 1.5× {10}4 (95% confidence).

    The medical humanities, a cross-disciplinary field of practice and research that includes medicine, literature, art, history, philosophy, and sociology, is being increasingly incorporated into medical school curricula internationally. Medical humanities courses in Writing, Literature, Medical Ethics and History can teach physicians-in-training communication skills, doctor-patient relations, and medical ethics, as well as empathy and cross-cultural understanding. In addition to providing educational breadth and variety, the medical humanities can also play a practical role in teaching critical/analytical skills. These skills are utilized in differential diagnosis and problem-based learning, as well as in developing written and oral communications. Communication skills are a required medical competency for passing medical board exams in the U.S., Canada, the UK and elsewhere. The medical library is an integral part of medical humanities training efforts. This contribution provides a case study of the Distributed eLibrary at the Weill Cornell Medical College in Qatar in Doha, and its collaboration with the Writing Program in the Premedical Program to teach and develop the medical humanities. Programs and initiatives of the DeLib library include: developing an information literacy course, course guides for specific courses, the 100 Classic Books Project, collection development of 'doctors' stories' related to the practice of medicine (including medically-oriented movies and TV programs), and workshops to teach the analytical and critical thinking skills that form the basis of humanistic approaches to knowledge.

    Public health surveillance systems should be evaluated periodically, and should involve an assessment of system attributes. Objective: Evaluate hospital-based surveillance of communicable diseases using the elements of timeliness and data quality. Method: Descriptive study was conducted of communicable diseases reported at The Cuban Hospital, Qatar during January 2012 to December 2013. The completeness of notifications were assessed for contact number, address, place of work, and date of symptom onset. Time between the symptoms onset and physician notification, time between physician and Supreme Council of Health notification and time between physician notification and lab confirmation were calculated for each case. Analysis: Percentage of cases with documented essential information and 95% confidence interval (CI) were determined. Mean and standard deviation (SD) of time were calculated. Results: 1065 patients were reported, 75% were male, 80% non-qataries and 91.5% were group 1 (high priority) diseases. Symptom onset date was documented in 91.5% (95% CI, 89.8; 93.2) of cases; contact number in 84.7% (82.5;86.8), with lower frequencies for address (68.1%, 65.3;70.9) and place of work (60.5%, 57.5;63.4). Diagnostic time for tuberculosis was 61.7 days (SD 93.0), acute hepatitis 18.5 days (SD 17.6), typhoid fever 17.0 days (SD 11.6 days), other diseases of sexual transmission 300.2 days, chronic hepatitis 165 days and AIDS 154.5 days. The time of notification to the Supreme Council of Health for group 1 diseases was 1.2 days (SD 1.4). Conclusion: Our results show that the quality of essential data and timeliness is not sufficient to meet the needs of the health system. Additional studies should focus on the evaluation of time delay for diagnosis of high priority diseases. PMID:25320693

    Hip fracture has never been studied before, either in Morocco or in the adjacent countries of the south bank of the Mediterranean Sea. The aim of this study was to investigate the incidence rate of hip fracture in 2002 in Rabat Province, a large area in the northwest of The Kingdom of Morocco, by the use of register information and medical records collected from the five public hospitals of the region. The hip fracture data were restricted to cervical or trochanteric types. There was a total of 150 hip fractures (83 in women and 67 in men) in the over-50-year-old population in the Province of Rabat during 2002. The age-adjusted 1-year cumulative incidence of hip fracture was 52.1/100,000 [95% confidence interval (CI) 40.9-63.3/100,000] in women and 43.7/100,000 (95% CI 33.3-52.2/100,000) in men. The standardized incidence rate against the 1985 US population was 80.7/100,000 (95% CI 78.5-93.0/100,000) for women and 58.5/100,000 (95% CI 47.9-68.1/100,000) for men. The mean (standard deviation) age of patients with a hip fracture was 70.7 (9.4) years for women and 70.4 (10.0) years for men. The overall female-to-male ratio of hip fracture was 1.19 for age-adjusted hip fracture incidence and 1.30 for standardized incidence. A marked increase in incidence rate was found for both men and women with increasing age, becoming exponential after the age of 50 years. The mean age for hip fracture was 70.7 (9.4) years in women and 70.4 (10.0) years in men (P > 0.05). Women had a cervical-to-trochanteric ratio of 0.97 compared to men, at 1.03. The characteristics of hip fractures described in this study suggest that fragility fractures occur in North Africa, although substantially less frequently than in most European, North American and Asian countries but more frequently than sub-Saharan African countries, in agreement with the north-south gradient observed in the epidemiology of osteoporosis. The low incidence of hip fragility fracture rate is most likely the result of

    This study assessed students' attitudes toward science in Qatar. A cross-sectional, nationwide probability sample representing all students enrolled in grades 3 through 12 in the various types of schools in Qatar completed the 'Arabic Speaking Students' Attitudes toward Science Survey' (ASSASS). The validity and reliability of the 32-item instrument, encompassing five sub-scales, have already been shown to be robust. The present analysis focused on responses from 1978 participants representing the students who completed the ASSASS in Arabic. Descriptive statistics were computed and a competing pair of multiple indicators multiple causes models is presented that attempt to link patterns in students' responses to the ASSASS with a set of indicators. The final model retained student age, gender, nationality (i.e. Qatari vs. Non-Qatari Arab), and school type as indicators. Findings from this study suggest that participants' attitudes toward science decrease with age, and that these attitudes and related preferences are influenced by students' nationality and the type of school they attend. Equally important, the often-reported advantages for male over female precollege students in terms of attitudes toward science were much less prominent in the present study.

    Economic globalization and advances in technology have made it more feasible and even necessary to develop international research collaborations in global public health. Historically, collaborations in global research described in the literature have been mostly “North-South” collaborations in which the more developed “North” country works together with a developing “South” country to conduct research in the latter. This type of collaboration has for the most part, represented unequal partnership and rarely left behind a lasting impact. Recently, the opportunity for a new kind of international research partnership has emerged in which the host country has significant financial resources, but relatively limited expertise in research methodology or techniques and research implementation. This type of collaboration features a relative equalization of power between the international partners. The purpose of this paper is to describe the process of building a successful research collaboration between a team in the United States and a team in Qatar, a rich Arabic nation in Gulf. We present a case study that provides an overview of our own project focused on the development of a culturally and linguistically adapted health care quality instrument for Qatar, discussing many of the benefits and challenges we encountered during each phase of instrument development. We present recommendations for researchers seeking sustainable and equitable partnerships with the Arab World. PMID:23121751

    Mangroves are unique ecosystems that dominate tropical and subtropical coastlines around the world. They provide shelter and nursery to wide variety of species such as fish and birds. Around 73 species of mangroves were recognized around the world. In Qatar, there is only one mangrove species Avicennia marina that is predominant along the northeastern coast. Assessing the health of these valuable ecosystems is vital for protection, management, and conservation of those resources. In this study, an integrated approach of chemical and remote sensing analysis was implemented to investigate the current status of the mangrove trees in Al-Khor, Qatar. Fifteen different A. marina trees from different locations in the mangrove forest were examined for their chlorophyll and nitrogen content levels. Soil analysis was also conducted to understand the effect of moisture on nitrogen availability. Results shows that currently, mangroves are in a good status in terms of nitrogen availability and chlorophyll levels which are related and both are key factors for photosynthesis. Remote sensing techniques were used for chlorophyll prediction. The results showed that these methods have the potential to be used for chlorophyll prediction and estimation.

    Sandflies are vectors of protozoa, viruses, and bacteria. To investigate the transmission of phleboviruses, a total of 8753 sandflies were collected in four foci of leishmania. A total of 16 distinct species were morphologically identified. Nested-PCR and cell culture screening for phleboviruses, using an assay targeting the polymerase gene, showed positive results for 19 pools of sandflies. Sequencing of the corresponding products confirmed the results and allowed identification of Toscana virus exclusively. Corresponding sandfly species originated from four different foci, and were different from those commonly reported in the literature. Sequence analysis shows that the Moroccan Toscana viruses belong to genotype B and appear close to the Toscana viruses isolated in France and Spain. This study reported the existence of the virus in the north, center and south of the country. The abundance and diversity of sandflies in Morocco, Mediterranean climate, would support the continuous circulation of Toscana virus in our country, posing a potential risk of emergence of these arboviruses.

    On the basis of a market survey, Centre National de l'Energie, des Sciences et des Techniques Nucléaires carried out a feasibility study of a commercial irradiation facility, identified the principal products which will be retained for the industrial applications and evaluated the projection of their volumes for the next five years. The site implementation of the irradiation plant is defined according to the national nuclear regulation and respecting the end users requirements. The costs of the irradiation services and the transport have been discussed and accepted by the industrials. This study shows that all the conditions are regrouped now in Morocco to introduce the irradiation technology to the industrial scale.

    Tsunami evacuation plan is an important tool to mitigate the tsunami impact. It is the most efficient way to save human lives, well before the waves reach the threatened coastal area, by providing evacuation routes and appropriate shelters. In this study, we propose a tsunami evacuation plan for the city of Tangier-Morocco. This plan is designed considering the tsunami threat from the tsunamigenic sources located in the SW Iberia Margin and using the inundation maps of the worst case to define the limit of flooding area. The evacuation plan is elaborated through modelling the required time for the threatened coastal population to reach the shelters. Results of this study will be useful for decision makers and local authorities in preventing the community resiliency for tsunami hazard. This work received funding from collaborative project ASTARTE - Assessment Strategy and Risk Reduction for Tsunamis in Europe Grant 603839, FP7.

    In this paper, we present a multivariate approach (waters, sediments, microfauna) concerning the environmental state of the Nador Lagoon (NE Morocco). The normal water quality parameters (salinity, pH, nutrients) of the dominant marine flows are altered by local fecal water effluents, urban discharges, sewages derived from a water treatment station, and residues originated in a slaughterhouse. The geochemical analyses carried out in surficial sediment samples show very high concentrations of all metals studied near an old iron mine and moderate contents between Nador and its treatment station. Ostracods are good bioindicators of these environmental impacts, with the presence of a highly brackish assemblage in the quieter, more confined areas or the appearance of opportunistic species under hypoxic conditions. In addition, these microcrustaceans are absent in polluted bottom sediments or areas with high hydrodynamic gradients, whereas they decrease in both density and diversity if the subaerial exposure increases.

    Digital diseases of cattle, as defined by the "International Council on Digital Diseases of the Ruminants" were studied on 32 farms with various management systems in Morocco. This study involved 953 cattle without lameness for claw examination and 89 lame cattle for detailed clinical examination and semiological trimming of the eight claws. Claw deformities, interdigital dermatitis and ungular erosion, chronic diffuse aseptic pododermatitis, circumscribed pododermatitis and deep digital diseases were described regarding their prevalence and clinical characteristics, including their distribution on fore and hind limbs, and on antero-medial, antero-lateral, postero-medial and postero-lateral claws. Interrelationships between different digital diseases and relationships between some digital diseases and environmental factors were searched by correlation studies. The results are compared with the characteristics of the same digital diseases in other countries.

    The prevalence of infection by Anaplasma spp. (including Anaplasma phagocytophilum) was determined using blood smear microscopy and PCR through screening of small ruminant blood samples collected from seven regions of Morocco. Co-infections of Anaplasma spp., Babesia spp, Theileria spp. and Mycoplasma spp. were investigated and risk factors for Anaplasma spp. infection assessed. A total of 422 small ruminant blood samples were randomly collected from 70 flocks. Individual animal (breed, age, tick burden and previous treatment) and flock data (GPS coordinate of farm, size of flock and livestock production system) were collected. Upon examination of blood smears, 375 blood samples (88.9%) were found to contain Anaplasma-like erythrocytic inclusion bodies. Upon screening with a large spectrum PCR targeting the Anaplasma 16S rRNA region, 303 (71%) samples were found to be positive. All 303 samples screened with the A. phagocytophilum-specific PCR, which targets the msp2 region, were found to be negative. Differences in prevalence were found to be statistically significant with regard to region, altitude, flock size, livestock production system, grazing system, presence of clinical cases and application of tick and tick-borne diseases prophylactic measures. Kappa analysis revealed a poor concordance between microscopy and PCR (k = 0.14). Agreement with PCR is improved by considering microscopy and packed cell volume (PCV) in parallel. The prevalence of double infections was found to be 1.7, 2.5 and 24% for Anaplasma-Babesia, Anaplasma-Mycoplasma and Anaplasma-Theileria, respectively. Co-infection with three or more haemoparasites was found in 1.6% of animals examined. In conclusion, we demonstrate the high burden of anaplasmosis in small ruminants in Morocco and the high prevalence of co-infections of tick-borne diseases. There is an urgent need to improve the control of this neglected group of diseases.

    Sharp linear gradients in maps of potential field data are generally assumed to result from sharp discontinuities or boundaries between rocks having different densities or magnetic susceptibilities and are usually associated with faults or other geological contacts. The computation of the horizontal gradients of the gravity field permits us to localize the limits of such blocks and then the fault locations. The horizontal derivative maxima of the Bouguer anomaly and its upward continuation at several heights show lineaments that could reflect the layout of faults and/or contacts and their dip directions. The application of this method to the Bouguer anomaly map of Morocco (with 19,571 points, using an average crustal density ρ = 2.67 g/cm3) allowed us to perform a multiscale analysis of the gravimetric lineaments of the country. The obtained structural map is consistent with several faults already identified in previous studies, and highlights five new major subsurface faults systems with location and dip: the Saghro fault system; Bou-Arfa Midelt fault system; Sidi Slimane Mezquitem fault; Ksar El Kebir-Chefchaouen fault and the Rifan West Mediterranean fault. In addition, this study suggests a new shape and localization for the Agadir-Oujda trans-Moroccan major fault with a NE-SW direction and 900 km length, subdividing Morocco into two main domains. The results of this study contribute to the improvement of the regional structural map of the north western part of Africa, which is situated within the convergence zone between Africa and Eurasia.

    Specific calcitic geological formations produced by water (speleothems and travertines) constitute an attractive environment for Humans through recent Quaternary period. The potential contribution of calcite analysis is exceptional because beyond the fact that it is close system for U-series dating, it also registers oxygen stable isotope (delta 18O) variations which reveal temperature fluctuations and carbon stable isotopes (12C and 13C) which reveal, different types of vegetation (herbaceous or arboreal) that successively appeared through icehouse and greenhouse periods. Hydrothermal travertine delta 13 C values are displaced to more positive value than the average of meteogene (fluvial) travertines. Growth stages of calcite can be dated using several radiochronological methods, extended from present time until 500 ka with U-series dating method, and using paleomagnetic studies for older Pleistocene period. Geochemical and paleomagnetic data allow constraining human development within the Quaternary chronostratigraphic scale which is compared to the marine isotopic scale as a reference. Meteogene travertines are less suitable for geochemical isotopic studies and radiochonology than hydrothermal travertine due to their numerous impurities. Here we present the first results obtained by the studies of Moroccan hydrothermal and fluvial travertine in 24 archeological sites distributed on the Moroccan territory. Two main information about growth periods are obtained: (1) travertine precipitation is effective from 1.1 millions years to Holocene, (2) growth periods are observed during both glacial and interglacial stages of the global climatic frame.The travertine prehistoric human occupation is discontinuous during the older periods but becomes more continuous since MIS 9 (350 ka). In the SE Morocco, in the Tafilalet area, flint fragments and Levallois nuclei were found upon travertine. They are probably relevant to Mousterian culture (from 200 to 35 ka.). Human

    A well dated Holocene speleothem (stalagmite) from the Middle Atlas Mountains in Morocco has been investigated for its continental climate record. The aim is to compile an improved understanding of the climatically complex triple point of the North Atlantic, Mediterranean and Saharan / Monsoonal climate realms in NW Africa. At present, only few studies concerning continental climate reconstructions from NW Africa have been published (Lamb et al. 1995, Cheddadi et al. 1998, Genty et al. 2006). Given the significance of this region, this lack of data forms a strong motivation for additional, well dated climate records. The speleothem (GP2) was sampled in the 'Grotte de Piste' (ca 800 m above sea level), mean annual precipitation is about 930 mm (mainly falling in the winter season) and the mean annual temperature is about 13° C. GP2 is 60 cm tall and grew - based on U/Th MC-ICP-MS data - continuously between 11.5 kyr BP (early Holocene) and 2.9 kyr BP (late Holocene). X-Ray Diffraction data indicate a mainly aragonitic mineralogy. 'Hendy tests' suggest that CaCO3 precipitation was close to isotopic equilibrium with respect to oxygen isotopes, however kinetic effects might have influenced carbon isotopes. Carbon and oxygen isotope data have been measured along a transect with increments of approximately 1 mm representing a resolution of about 15 yrs. Highly covariant oscillations in δ13C and δ18O with an average cyclicity of about 410 yrs. are observed. These oscillations coincide with macroscopically visible high density and low density layers, possibly reflecting a higher or lower amount of inclusions and perhaps higher and lower growth rates. Geochemical analysis of speloan aragonite is accompanied by cave monitoring that has started in November 2009. Parameters quantified include: drip water parameters, cave air humidity, pCO2 and cave air temperature. Precipitation experiments using watch glasses will also be performed.

    Frequency-dependent attenuation (Q- 1) in the crust of northern Morocco is estimated from Lg-wave spectral amplitude measurements every quarter octave in the frequency band 0.8 to 8 Hz. This study takes advantage of the improved broadband data coverage in the region provided by the deployment of the IberArray seismic network. Earthquake data consist of 71 crustal events with magnitudes 4 ≤ mb ≤ 5.5 recorded on 110 permanent and temporary seismic stations between January 2008 and December 2013 with hypocentral distances between 100 and 900 km. 1274 high-quality Lg waveforms provide dense path coverage of northern Morocco, crossing a region with a complex structure and heterogeneous tectonic setting as a result of continuous interactions between the African and Eurasian plates. We use two different methods: the coda normalization (CN) analysis, that allows removal of the source and site effects from the Lg spectra, and the spectral amplitude decay (SAD) method, that simultaneously inverts for source, site, and path attenuation terms. The CN and SAD methods return similar results, indicating that the Lg Q models are robust to differences in the methodologies. Larger errors and no significant frequency dependence are observed for frequencies lower than 1.5 Hz. For distances up to 400 km and the frequency band 1.5 ≤ ƒ (Hz) ≤ 4.5, the model functions Q(f) = (529- 22+ 23)(f/1.5)0.23 ± 0.06 and Q(f) = (457- 7+ 7)(f/1.5)0.44 ± 0.02 are obtained using the CN and SAD methods, respectively. A change in the frequency dependence is observed above 4.5 Hz for both methods which may be related to the influence of the Sn energy on the Lg window. The frequency-dependent Q- 1 estimates represent an average attenuation beneath a broad region including the Rif and Tell mountains, the Moroccan and Algerian mesetas, the Atlas Mountains and the Sahara Platform structural domains, and correlate well with areas of moderate seismicity where intermediate Q values have been obtained.

    The study of hepatitis B virus (HBV) genomic heterogeneity has become a major issue in investigations aimed at understanding the relationship between HBV mutants and the wide spectrum of clinical and pathological conditions associated with HBV infection. The objective of the current study was to find out the pattern of HBV genotypes circulating in Morocco and to investigate the precore (PC) and basal core promoter (BCP) mutants' status in Moroccan chronic hepatitis B patients. Viral genotypes were determined in 221 chronic carriers using INNO-LiPA HBV assay and hemi-nested PCR. Phylogenetic analysis was performed in 70 samples, and multiplex PCR method was used to confirm some genotyping results. PC and CP mutants were determined using Inno-Lipa. All isolates were successfully genotyped. The genotype distribution was D in 90.45% of cases, A (5.9%), E (1 case), and mixed genotypes (5 A/D and 2 D/F) in 3.17% patients. HBV carried in the HBV/D samples could be assigned to D7 (63.3%), D1 (32.7%) and 2% of strains to each D4 and D5, all HBV/A belonged to A2 subgenotype and HBV/E strain could not be sub-genotyped. In 70 studied strains, HBV mutants were detected in 88.6% of cases; PC mutants were detected in (40%) of patients and 21.5% present a mixture of wild type and G1896A mutation. BCP mutants were observed in 65.7% of cases, 22.9% were found to have the T1762/1764A double mutation, 18.6% had A1762/1764T mutation and 22.9% of patients showed the A1762T/G1764A double mutation with either A1762T/G1764T mutation. Co-infection by PC and BCP mutants was detected in 52.9% of cases. Movement from place to place most likely shapes the observed genotype distribution and consequent prevalence of genotypes other than A2 or D7 in this population. High circulation of PC and BCP mutants is common in chronic hepatitis B infection in Morocco.

    Little is known regarding attitudes of healthcare professional students towards team-based care in the Middle East. As modernization of health systems is rapidly occurring across the Gulf Cooperation Council countries, it is important for students to engage in interprofessional education (IPE) activities. The objective of this study was to assess pre-clinical students' attitudes towards interprofessional healthcare teams after completion of their first IPE activity. A previously validated questionnaire was distributed to 25 pharmacy and 17 nutrition students at Qatar University after participation in an IPE event. Questions related to quality of team-based care and physician centricity. Results showed high agreement regarding high quality care provided by teams yet students were unsure of the value of team-based care when considering required time for implementation. Results provide baseline data for future studies to assess student attitudes throughout the professional programs and give valuable insight for future IPE program design in the Middle East.

    This paper presents data from the first major survey of the diversity, biology and fisheries of elasmobranchs in the Persian (Arabian) Gulf. Substantial landings of elasmobranchs, usually as gillnet by-catch, were recorded in Kuwait, Qatar and the Emirate of Abu Dhabi (part of the United Arab Emirates), although larger elasmobranchs from targeted line fisheries were landed in Abu Dhabi. The elasmobranch fauna recorded was distinctive and included species that are undescribed, rare and have a highly restricted known distribution. Numerical abundance was dominated by sharks (c. 80%), of which carcharhinids were by far the most important. The milk shark Rhizoprionodon acutus and whitecheek shark Carcharhinus dussumieri together comprised just under half of all recorded individuals. Around 90% of recorded sharks were small (50-90 cm total length, L(T) ) individuals, most of which were mature individuals of species with a small maximum size (<100 cm L(T) ), although immature individuals of larger species (e.g. Carcharhinus sorrah and other Carcharhinus spp.) were also important. The most frequently recorded batoid taxa were cownose rays Rhinoptera spp., an undescribed whipray, and the granulated guitarfish Rhinobatos granulatus. The first size, sex and maturity data for a wide range of Gulf elasmobranch species are presented (including L(T) at 50% maturity for males of four shark species) and include some notable differences from other locations in the Indo-West Pacific Ocean. A number of concerns regarding the sustainability of the fishery were highlighted by this study, notably that most of the batoid species recorded are classed by the IUCN Red List as vulnerable, endangered, data deficient or not evaluated. Despite their considerable elasmobranch landings, none of the three countries sampled have developed a 'Shark Plan' as encouraged to do so under the FAO International Plan of Action: Sharks. Furthermore, Kuwait and Qatar currently report zero or no elasmobranch

    One response to humanity's unsustainable use of natural resources and consequent degradation, even destruction of the environment, is to establish conservation areas to protect Nature and preserve biodiversity at least in selected regions. In Qatar, the government has shown strong support for this approach, confronted by the environmental consequences of oil and gas extraction and rapid urban development, by designating about one-tenth of the country a conservation area. Located in the west of the peninsula, it comprises the Al Reem Reserve, subsequently declared a UNESCO Biosphere Reserve. Several approaches have figured in conservation, currently popular is co-management featuring participation of the local population, which recognises that people's activities often contribute to today's environment, with the promotion of bio-cultural diversity. However, these assumptions may not hold where rapid social and cultural change occurs, as in Qatar. We explore the implications of such change, notably in land use. We detail changes resulting with the move from nomadic to sedentary lifestyles: in land access, which now features tribal-state control, and herding strategies, which now feature migrant labour and depend on imported fodder and water, underwritten by the country's large gas and oil revenues. Current stocking arrangements - animals herded in much smaller areas than previously - are thought responsible for the degradation of natural resources. The place of animals, notably camels, in Qatari life, has also changed greatly, possibly further promoting overstocking. Many local people disagree. What are the implications of such changes for the participatory co-management of conservation areas? Do they imply turning the clock back to centrally managed approaches that seek to control access and local activities?

    The purpose of this study was to determine the prevalence and severity of dental caries and dental fluorosis, as well as various other oral conditions, in 2378 subjects (ages seven to 60) living in the fluoridated area of Khouribga and the non-fluoridated area of Beni Mellal, Morocco. The community index of dental fluorosis (CFI) ranged from 1.99 to 2.80 in the high-fluoride area: Over 90% of the population was affected, and more than one-third of the subjects showed moderate dental fluorosis. However, in Beni Mellal, more than 96% of the dentate subjects examined were free of dental fluorosis, and the CFI of 0.02 was considered not significant. Significant differences were observed between the two areas with respect to caries prevalence. DMFT and DMFS indices were markedly lower in the fluorosis area of Khouribga. The oral conditions of subjects appeared to be better in Khouribga, where the gingival and calculus indices were significantly lower than in Beni Mellal. The analyses of covariance showed no significant differences in plaque accumulation (PI) between the Khouribga and Beni Mellal samples. However, a close statistical correlation was found between PI and GI in Beni Mellal and Khouribga.

    Enosiaspis hrungnir gen. et sp. nov., a new species of marrellomorph arthropod from the Lower Ordovician (Tremadocian) Fezouata biota of Morocco, is described. This taxon is characterised by the possession of a cordiform dorsal carapace with an anterior notch and a doublure-like structure formed from fused marginal spines, covering the entire body. The head comprises at least five segments which bear an anterior pair of antenna, followed by three pairs of potentially biramous, geniculate appendages. The trunk possesses around 25 pairs of delicate, almost filamentous appendages, which decrease in size posteriorly. Similar features are also found in Xylokorys chledophilia from the Silurian of England, and Vachonisia rogeri from the Devonian of Germany, indicating acercostracan affinities for E. hrungnir. This was tested using a phylogenetic analysis which resolved this taxon as sister taxon to a group composed of the formerly mentioned taxa. The similarities between the ventral spinose carapace doublure of E. hrungnir and the mediolateral spines of marrellid marrellomorphs further support claims that the dorsal shield of acercostracans evolved from the fusion of spinose anlagen, akin to the formation of the carapace of crustaceans.

    Across the northwestern Tabular Middle Atlas of Morocco there are many examples of landscapes, rocks and fossils that provide key evidence of a particular moment or period in Earth history. Such Earth heritage sites are important for educating the general public in environmental matters. They also serve as tools for demonstrating sustainable development and for illustrating methods of site conservation as well as remembering that rocks, minerals, fossils, soils, landforms form an integral part of the natural world. The significance of certain sites for aesthetic or tourism reasons is obvious. There are numerous geosites, which could contribute to effective exploitation of geotourism, often in conjunction with ecotourism. The strategy employed to such sites involves close consultation with all communities in the vicinity of the respective geosite and is not only aimed at tourism and education, but also at sustainable improvement of the infrastructure of the people of this area. Geological heritage sites, properly managed, can generate employment and new economic activities, especially in regions in need of new or additional sources of income.

    In Morocco, socioeconomic fields are vulnerable to weather extreme events. This work aims to analyze the frequency and the trends of temperature and rainfall extreme events in two contrasted Moroccan regions (the Tensift in the semi-arid South, and the Bouregreg in the sub-humid North), during the second half of the 20th century. This study considers long time series of daily extreme temperatures and rainfall, recorded in the stations of Marrakech and Safi for the Tensift region, and Kasba-Tadla and Rabat-Sale for the Bouregreg region, data from four other stations (Tanger, Fes, Agadir and Ouarzazate) from outside the regions were added. Extremes are defined by using as thresholds the 1st, 5th, 90th, 95th, and 99th percentiles. Results show upward trends in maximum and minimum temperatures of both regions and no generalized trends in rainfall amounts. Changes in cold events are larger than those for warm events, and the number of very cold events decrease significantly in the whole studied area. The southern region is the most affected with the changes of the temperature regime. Most of the trends found in rainfall heavy events are positive with weak magnitudes even though no statistically significant generalized trends could be identified during both seasons.

    This study is based on a site survey carried out in the capital city of Morocco, Rabat. For this aim, we used a technique based on the recording and processing of seismic ambient noise to characterize local geological conditions in terms of the dynamic response of soil during earthquakes. This technique consists of an assessment of the spectral ratio of the horizontal to vertical components of microtremors recorded at the surface during a few minutes, and allows determination of the fundamental period and the maximum amplification factor at the site of measurement. We applied this technique in the city of Rabat to obtain distribution maps of dominant periods and amplification factors assessed in more than 250 sites. In order to discuss the results of this study, we used the information available in this zone about the lithology and topography to correlate the obtained values of dominant periods and amplification factors with the ground conditions. Finally, we established a microzoning map of the city of Rabat based on the contours of dominant periods. The microzoning map established in this study can be used by engineers and decision makers for urban and land use planning and also as a guide in reduction of the seismic vulnerability of buildings.

    The multi-mycotoxin contamination of ninety-eight (98) couscous semolina samples collected from various areas in Morocco was investigated in this study. Samples were surveyed for the presence of 22 mycotoxins (four aflatoxins, ochratoxin A, diacetoxiscyrpenol (DAS), three fumonisins, beauvericin (BEA), deoxynivalenol (DON), 15-acetyl-deoxynivalenol (15-ADON), 3-acetyl-deoxynivalenol (3-ADON), nivalenol (NIV), sterigmatocystin (STG), zearalenone (ZEA), four enniatins, T-2 and HT-2 toxins). Results showed that 96 out of 98 total couscous samples (98%) were contaminated by at least one mycotoxin. Enniatin B (ENB), Enniatin B1 (ENB1), Enniatin A1 (ENA1) and zearalenone (ZEA) have shown the highest incidences in contaminated samples. The dietary exposure was estimated to be 1.02, 0.57, 0.06, 0.57 and 0.3μg/kgbw/day for the sum of (DON+3-ADON+15-ADON), fumonisins (FB1+FB2+FB3), the sum of (T2+HT-2), NIV and ZEA, respectively.

    This report is an overview of the energy market in four West African countries: The Ivory Coast, Morocco, Nigeria, and Senegal. We feel these countries are representative of the West African region. Together they account for 75% of the total energy use in West Africa, 78% of GDP, and 76% of population. The purpose of the study is to analyze the evolution of energy demand in the context of the general socio-economic background of the region. The study also examines energy supply and trade related to the energy sector. The analysis focuses on the study of commercial fuels. Although we have reviewed studies of wood, solar, wind, and agricultural residues, we leave out detailed discussions of these non-commercial energy forms. The first part of the report is an assessment of the trends in energy demand in the four study countries. We discuss the main factors driving energy demand sector by sector. This is followed by a review of the primary energy resources of the countries, and of the capacity for production of secondary fuels. The last section looks at energy trade, with particular emphasis on the role of the United States.

    Mixed phenotype acute leukemia (MPAL) includes biphenotypic and bilineal types of leukemia, which constitute rare subtypes that require individualized therapy. Outcomes in Moroccan patients with MPAL are unknown. Among 1264 patients with acute leukemia, 20 were classified as having MPAL, including 17 with biphenotypic acute leukemia (1.3%) and 3 with bilineal leukemia (0.2%). There were 8 adults and 12 children. In 12 cases (60%), leukemic blasts expressed myeloid and T-lymphoid antigens, and, in 5 cases (25%), leukemic blasts expressed B lymphoid antigens plus myeloid antigens. Patients were initially treated on protocols for acute myeloid leukemia (n=4), acute lymphoblastic leukemia (ALL, n=14), or with palliative care (n=2). The probability of survival at 2 years in MPAL cases was 52%± 14%. Six of the 12 patients younger than 15 years remain alive versus 1 of 8 adult patients. Patients treated with ALL-directed therapy had significantly higher overall survival than those treated with acute myeloid leukemia-directed therapy (P=0.003). There was no association between the phenotypic characteristics and the clinical outcome (P=0.83). In conclusion, MPAL represents 1.5% of acute leukemia in Morocco. The prognosis is poor, but initial treatment with therapy directed toward ALL, improved supportive care, and the prevention of abandonment of therapy may improve outcomes in this subgroup of patients.

    The studied area is on the west of Morocco in the High moroccan western Atlas. It is limited by Amizmiz and the Essaouira city. Lower Cretaceous - Barremian, Aptian and Albian- of Essaouira basin show tickness and variable lithology from east to west basin. The Barremian is caracterised by clays and calcareous, Aptian and Albian are caracterised by several typical marls and carbonates. The Albian is homogeneous in all the basin. Only Barremian sommit Aptian are very rich on planctonic Foraminifera, the base of this level is poor on planctonic Foraminifera. The Albian present several bentic Foraminifera like Pleurostomella. Biostratigraphy and micropalaentology study, essentially, based on planctonic Foraminifera can listing 24 species indicating 13 biozones in this area. The Barremian interval is composed of three biozones : - Hedbergella sigali biozone indicating the Early Barremian. - Hedbergella similis biozone, Globigerinneloïdes gottisi and Globigerinelloïdes duboisi are incated the Upper Barremian. The Aptian is recognised by six biozones : - Early Aptian interval is caracterised by the Schackoina cabri, Globigerinelloïdes ferreolensis, Globigerinelloïdes algerianus, Hedbergella gorbachikae and Hedbergela trochoïdea biozones. - Upper Aptian is recognised by Ticinella bejaouensis and base of Hedbergella planispira biozones. The Albian is caracterised by three biozones : - Hedbergella planispira biozone of Lower Albian. - Ticinella primula and Biticinella breggiensis biozones who caracterised the Upper Albian. Planomalina buxtorfi is also present but smal size. This study was followed by Pr. Saloua Gargouri Razgallah ( FS- Tunis- Tunisia)

    Saccharomyces cerevisiae is a cosmopolitan yeast, widely used in agro-alimentary and pharmaceutical industry. Its impact in human pathology is rare, but maybe still underestimated compared to the real situation. This yeast is currently considered as an emerging and opportunistic pathogen. Risk factors are immunosuppression and intravascular device carrying. Fungemias are the most frequent clinical forms. We report the first case of S. cerevisiae invasive infection described in Morocco, and to propose a review of the literature cases of S. cerevisiae infections described worldwide. A 77-year-old patient, with no notable medical history, who was hospitalized for a upper gastrointestinal stenosis secondary to impassable metastatic gastric tumor. Its history was marked by the onset of septic shock, with S. cerevisiae in his urine and in his blood, with arguments for confirmation of invasion: the presence of several risk factors in the patient, positive direct microbiological examination, abundant and exclusive culture of S. cerevisiae from clinical samples. Species identification was confirmed by the study of biochemical characteristics of the isolated yeast. Confirmation of S. cerevisiae infection requires a clinical suspicion in patients with risk factors, but also a correct microbiological diagnosis.

    The coastal aquifer system of Chaouia is recognized as one of the most important aquifers in Morocco that is affected by salinization in the coastal fringe. The purpose of this study is to highlight the origin of salinization by sampling and analyzing groundwater from 44 wells for major elements. This study was carried out in May 2011. The results indicate that, in the central and downstream parts, the dominant facies are Mg2+, Na+ and Cl-, while Ca2+ and HCO3- dominate in the upstream zones. Ion exchange processes, under seawater intrusion, control the concentration of ions such as calcium, magnesium and sodium. Moreover, groundwater is oversaturated with respect to carbonate minerals (calcite and dolomite), and under-saturated with respect to evaporate minerals (gypsum, halite). The contribution of dissolved halite and gypsum in the groundwater mineralization is revealed by their positive correlation between (Na + Cl) and (Ca + SO4), respectively. Furthermore, the comparison of the hydrochemical results to drinking water quality standards by World Health Organization (2008) shows that more than a half of the water sampled is not suitable for drinking purposes, especially with respect to high levels of EC, TDS, Cl- and NO3-. In addition, high mineralization is found to be a consequence of seawater intrusion and anthropogenic activities.

    Mediterranean forests in northern Morocco have been studied. Tree species composition and abundance were investigated in 84 forest sites, distributed throughout the sandstone formation of the Tangier region. The relative abundance of 15 tree and arborescent shrub species was related, by ordination analysis, to altitude, disturbance by fire, and soil fertility. High-elevation forests were dominated by Cedrus atlantica, Quercus pyrenaica and Pinus pinaster. Sacred forests (protected as holy burial places) had a distinct stand structure, and were considered as refuges, for maintaining biodiversity at landscape scale. The evergreen oak Quercus suber and the semideciduous Quercus canariensis co-dominated the lowland forests. The mean basal area of the studied forests was 34 m 2 ha -1. The mean trunk size (dbh) for Q. suber was 24 cm and for Q. canariensis 36.5 cm; in both cases there were indications of declining regeneration at population level. A comparative biogeographical analysis with the equivalent region in southern Spain (separated by the Strait of Gibraltar; 14 km wide), indicated a possible biodiversity loss in the Moroccan forests.

    The autochthonous Cretaceous in the Rharb basin of northern Morocco is located underneath a cover of neogene sediments and of the Prerif nappe olistostrome, which was emplaced during the Tortonian 7 m.y. The presence of infranappe Cretaceous sediments is documented in a few onshore wells in the Rharb basin and in the adjacent Prerif Rides area, as well as in the Rif Mountains. Their presence in the deeper portion of the Rharb basin is difficult to detail because of poor seismic resolution data beneath dispersive prerif nappe. A recent study of offshore seismic data acquired by PCIAC in 1987 indicates that the infranappe interval can be more than 1500 m thick in some of the offshore Kenitra area. These sediments have seismic signatures that would correspond to Middle Cretaceous transgressions, culminating with a Turonian highstand. Their deposition systems were located on the northern and western flanks of the Meseta and were followed by a hiatus lasting until the Miocene. Regional studies of gravity and magnetic data provide and additional understanding of the Rif province, its evolution, and the possible presence of autochthonous Cretaceous sediments below the prerif nappe cover. The infranappe of Rharb basin has a good potential to develop into a major hydrocarbon play with the presence of middle Cretaceous reservoir rocks, Turonian-Cenomanian black shale source rocks, as well as the timely combination of trap formation, source rock maturation, and hydrocarbon migration.

    Environmental pollution of fish with organic contaminants is a topic of rising attention in Morocco. Polycyclic aromatic hydrocarbons (PAH) are prominent organic contaminants which are rapidly metabolized in fish. Their metabolites are accumulated in the bile fluid and can be used to assess PAH exposure. The two PAH metabolites 1-hydroxypyrene and 1-hydroxyphenanthrene were quantified in European eels (Anguilla anguilla) from two Moroccan river systems by high-performance liquid chromatography with fluorescence detection. Mean values ranged from 52 to 210 ng/mL 1-hydroxypyrene and from 61 to 73 ng/mL 1-hydroxyphenanthrene. The overall concentrations of PAH metabolites in eel from Morocco appeared moderate compared to eel from European rivers and coastal sites. The present study provides first information on concentrations of PAH metabolites in fish from Morocco.

    Around the world and especially in summer, the scorpion envenomation is a real public health problem. In Morocco, its gravity is due to the diversity of genera of the Buthidae family whose their venom is potentially lethal, mainly the genus Androctonus, Buthus and Hottentota. The areas most affected by this problematic are the central and southern of Morocco. The lethality of scorpion's venom primarily affects children. It is rich in neurotoxic polypeptides that have targeted ion channel membrane Na(+), K(+) activated or not by Ca(++). The toxins polymorphism causes pathophysiological disorders. The diversity of symptomatic treatment in the absence of immunotherapy is due to variability in clinical pictures, which depends on the species involved and the patient at risk. The objective of this review is to highlight the magnitude of the scorpion envenomation by describing its epidemiological characteristics, elucidate the pathophysiological effects of the venom of the most dangerous scorpions in Morocco the genus Androctonus, Buthus and Hottentota, and their therapeutic treatment.

    Tick-borne relapsing fever (TBRF) is caused by Borrelia spirochetes transmitted to humans by Argasid soft ticks of the genus Ornithodoros. We investigated the presence of Ornithodoros ticks in rodent burrows in nine sites of the Gharb region of northwestern Morocco where we recently documented a high incidence of TBRF in humans. We assessed the Borrelia infection rate by nested PCR and sequencing. All sites investigated were colonized by ticks of the Ornithodoros marocanus complex and a high proportion of burrows (38.4%) were found to be infested. Borrelia infections were observed in 6.8% of the ticks tested. Two Borrelia species were identified by sequencing: B. hispanica and B. crocidurae. The discovery in northwestern Morocco of Ornithodoros ticks infected by B. crocidurae represents a 350 km range extension of this Sahelo-Saharan spirochete in North Africa. The spread of B. crocidurae may be related to the increasing aridity of northwestern Morocco in relation to climate change.

    2015-01-01

    Previous population genetic studies on the Mediterranean mussel Mytilus galloprovincialis have shown the existence of two well differentiated sets of populations around Southern European coasts, one Atlantic and another Mediterranean. Those two population pools are kept apart by the Almería - Oran Oceanographic Front (AOOF), an oceanographic discontinuity acting either as a cause of such differentiation or simply as a means of maintaining two historically differentiated gene pools. The role of the Gibraltar Strait at shaping mussel larval flow entering the Alboran Sea has been much less addressed, especially regarding mussel swarms inhabiting the northern coast of Morocco. The present study applies seven microsatellite markers to describing the genetic status of northern Moroccan populations of M. galloprovincialis and their relationship with the two well-characterized mussel gene pools from southern Europe. We show that the Atlantic Iberia gene pool extending continuously from the Cantabrian Sea (NE Iberia) to the Alboran Sea (SE Iberia) up to the AOOF is well differentiated from the Atlantic Moroccan mussel. Either an oceanographic barrier or a limited larval dispersal or both, are required to explain this unexpected intercontinental differentiation regarding previous studies on this species. Populations from Atlantic Morocco conformed to a single gene pool (FST ± SD = 0.012 ± 0.007) as opposed to the reported latitudinal barrier to gene flow at Cape Ghir in western Morocco. Additionally, a significant restriction to gene flow was observed between Atlantic Morocco and Alboran Morocco (FST ± SD = 0.038 ± 0.010) in contrast to the reported mussel genetic continuity along the Iberian coast up to AOOF. Three major mussel gene pools appear to meet at this crossroads between continents and between seas, namely, a Mediterranean European subpopulation, an Atlantic Iberia subpopulation including the Alboran Sea, and an Atlantic Morocco subpopulation.

    The authors describe the factors that led Weill Cornell Medical College in Qatar (WCMC-Q) to establish the Center for Cultural Competence in Health Care from the ground up, and they explore challenges and successes in implementing cultural competence training.Qatar's capital, Doha, is an extremely high-density multicultural setting. When WCMC-Q's first class of medical students began their clinical clerkships at the affiliated teaching hospital Hamad Medical Corporation in 2006, the complicated nature of training in a multicultural and multilingual setting became apparent immediately. In response, initiatives to improve students' cultural competence were undertaken. Initiatives included launching a medical interpretation program in 2007; surveying the patients' spoken languages, examining the effect of an orientation program on interpretation requests, and surveying faculty using the Tool for Assessing Cultural Competence Training in 2008; implementing cultural competence training for students and securing research funding in 2009; and expanding awareness to the Qatar community in 2010. These types of initiatives, which are generally highly valued in U.S. and Canadian settings, are also apropos in the Arabian Gulf region.The authors report on their initial efforts, which can serve as a resource for other programs in the Arabian Gulf region.

    The rapid urbanization, industrialization and economic expansion in the Middle East have led to increased levels of atmospheric pollution with important implications for human health and climate. We applied the online-coupled meteorological and chemical transport Weather Research and Forecasting/Chemistry (WRF-Chem) model over the Middle Eastern domain, to simulate the concentration of gas and aerosols with a special focus over the state of Qatar. WRF-Chem was set to simulate pollutant concentrations along with the meteorology-chemistry interactions through the related direct, indirect and semi-direct feedback mechanisms. A triple-nested domain configuration was used with a high grid resolution (1x1 km2) over the region of Qatar. Model predictions are evaluated against intensive measurements of meteorological parameters (temperature, relative humidity and wind speed) as well as ozone and particulate matter taken from various measurement stations throughout Doha, Qatar during summer 2015. The ability of the model to capture the temporal and spatial variability of the observations is assessed and possible reasons for the model bias are explored through sensitivity tests. Emissions of both fine and coarse mode particles from construction activities in large urban Middle Eastern environments comprise a major pollution source that is unaccounted for in emission inventories used so far in large scale models for this part of the world.

    The intracontinental High and Middle Atlas mountain belts in Morocco intersect to form the southern and western margins of the Missour basin, an intermontane basin formed as a result of the uplift and inversion of the Mesozoic Atlas paleorifts. These rifts were areas where the crust was greatly attenuated and more subject to deformation in response to nearby plate boundary tectonics. Data from observations based on seismic reflection profiles and wells over the Missour basin for hydrocarbon exploration and field mapping were used to understand the basin evolution, structural styles, and inversion timing of the nearby Atlas Mountains. Hercynian and Mesozoic normal faults were reactivated into high-angle reverse and thrust faults in the Mesozoic during the Jurassic, Early Cretaceous (early Alpine phase), and the Paleogene (late Alpine phase). The reactivation of synrift normal faults of the paleo-Atlas rifts inverted previous half grabens into anticlinal structures, with the axis of the half graben centered below the axis of the inverted anticline. The resulting inverted fold geometries are controlled by the geometries of the extensional planar or listric faults. The Atlas paleorift system is one of the largest rift systems in Africa. Little hydrocarbon exploration has occurred within the Atlas Mountains and the margins of the paleo-Atlas rift system. Inversion of synrift structures can lead to both the destruction and preservation of synrift traps and the creation of new hydrocarbon traps. The study of the effects of inversion in the Missour basin may lead to the discovery of footwall subthrust hydrocarbon traps in the Mesozoic sedimentary sequence of the Atlas Mountains.

    - In Morocco, reducing soil erosion and land degradation is a national priority for improving soil quality and protecting downstream water quality and quantity. The combined use of Cs-137 and Be-7 techniques permit to estimate long and short term erosion and deposition magnitudes under different agro-environment and climatic conditions and then to evaluate the effectiveness of soil conservation practices. Case studies using Cs-137 and Be-7 were carried out in three Moroccan agricultural sites: Marchouch, Harchane and Oued Mellah located in Rabat, Tétouan and Chaouia-Ouardigha regions, respectively. In these sites, fallout Cs-137 measurements allowed a retrospective assessment of long term (50-60 years) soil redistribution rates while fallout Be-7 (half-life of 53 days) was used to document short term soil erosion associated with rainfall events for different tillage systems and land uses. Long term soil erosion rates of the three regions evaluated by the Cs-137 method, ranged from 8 to 58 t/ha/yr. Mostly located in the upslope part of the fields, the eroding zones represented more than 70% of the total area. For the experimental sites in Rabat and Tétouan, the results obtained using Be-7 indicated that soil loss has been reduced significantly under no-till as compared to conventional tillage. Indeed, soil erosion rates were lowered by 50% for the Marchouch site and by 40% for the Harchane site. Concerning the Oued Mellah watershed, the results highlighted that high density Atriplex plantations have reduced soil loss by approximately 60 to 80%, while for the site under fruit plantations and cereals, soil erosion has been decreased by 58%.

    Knowledge of the distribution of water vapor in both time and space is essential for understanding weather and global climate change. This study presents the results of precipitable water vapor (PWV) estimates from GPS data for three continuously operating GPS stations in Morocco (Rabat, Tetouan, and Ifrane) for the period 2001 to 2007. The conversion of atmospheric delays to integrated water vapor was carried out using interpolated surface meteorological parameters derived from the global numerical weather model analysis from the National Centers for Environmental Prediction (NCEP). The surface pressure extracted from the NCEP model was compared with observations provided from the synoptic network of the Moroccan Meteorological Agency (DMN). Good agreement was found between the two data sets with a bias of less than 1hPa. We compared the GPS derived PWV with the nearest radiosondes at the Rabat and Tetouan stations. The results show overall good agreement between the two data sets (mean difference < 2.5Kg/m2). The NCEP PWV compared well with GPS observations with a mean difference of less than 2.5 Kg/m2 and a standard deviation of less than 3.5 Kg/m2, confirming the potential of ground based GPS to provide an accurate and continuous description of water vapor field variations. The study showed by means of GPS, radiosondes and both NCEP model, a clear seasonal cycle of PWV with the highest values recorded during June, July, August, and September, peaking at 29 Kg/m2. The highest seasonal modulations seen at the 3 GPS stations were linked to large-scale atmospheric circulation.

    The objectives of this epidemiological study on cystic echinococcosis (CE) in Morocco (2001-2004) were to update the prevalence of CE in different animal species living in the most important areas of the country and to collect protoscoleces and germinal layers for genetic research purposes. The post mortem inspection concerned 2948 sheep, 2337 goats, 618 cattle, 482 camels and 455 equines (325 horses, 60 mules and 70 donkeys) in five different regions: the Rif (Mediterranean coast and high mountains of the Rif), the Loukkos (Atlantic northwest plain), the center (Rabat and Casablanca regions), the Middle Atlas mountains and the south (arid and semi desert areas). The global CE infection prevalence rates obtained were 22.98% in cattle, 10.58% in sheep, 12.03% in camels, 17.80% in equines and 1.88% in goats. The infection rates were especially high in the Middle Atlas in cattle (48.72%) and in the Loukkos in cattle and sheep (37.61 and 31.65%, respectively). The majority of infected cattle (49.6%) and sheep (52.1%) had hydatid cysts in both liver and lungs. Except for cattle, the liver was more infected than lungs in all the other animal species. Animals more than 5 years old were the most infected in all species. The mean CE infection rates of these animals were about 56% in cattle, 40% in sheep, 20% in camels, 17.80% in equines and 7% in goats. These rates were much higher in the Loukkos (85% of cattle and 59% of sheep) and in the Middle Atlas (68% of cattle and 45% of sheep) than in the other regions. Results showed that Echinococcus granulosus is in an endemic steady state with no evidence of protective immunity in the intermediate hosts. The mean numbers of infections per year are 0.099 for cattle, 0.063 for sheep, 0.03 for camels and 0.010 for goats.

    Field studies on cannabis cultivation have provided socio-economic data relating to, inter alia, production, yield and income. But only laboratory analyses of cannabis plants can provide information on their chemical composition and their levels of psychoactive constituents, thus enabling them to be classed as a drug type or a fibre type. The present study, which covers cannabis in its fresh, dried and powdered forms, drew on fresh samples, obtained on the day they were harvested or immediately after preparation; that was done in order to prevent any alteration in the A-9-tetrahydrocannabinol (THC) caused by the oxidation that takes place as the product ages. The purpose of this study is to determine the THC level in 245 specimens obtained from 30 cannabis plots in three provinces of northern Morocco: Al Hoceima and Chefchaouen, where cannabis cultivation has a long tradition, and Larache, where cannabis cultivation has started only recently. Qualitative analysis using high performance liquid chromatography with diode array detection revealed the presence of both the acid and the decarboxylated form of the main cannabinoids, cannabidiol, THC and cannabinol, and gas chromatography/mass spectrometry was used for the characterization of minor cannibinoids. Quantitative analysis using gas chromatography coupled with mass spectrometry made it possible to determine the average delta-9-THC content of cannabis in its fresh form (0.5 per cent), its dry form (2.21 per cent) and its powdered form (8.3 per cent). The results show that the traditional areas of cannabis cultivation--Al Hoceima and Chefchaouen--produce cannabis with a higher delta-9-THC content than the Larache region. In addition, the present study establishes that male plants, often considered deficient in delta-9-THC, contain levels of the same order as those recorded for female plants, both in the leaves and in the tops.

  7. Heavy metals distribution in sediments of Nador lagoon (Morocco)

    The Nador lagoon is a paralic system, located North-East of Morocco. At the present time this ecosystem undergoes an anthropic stress induced by urban, industrial and agricultural releases, and also by fishery activity which enriches this ecosystem in organic and inorganic wastes. A geochemical study has been undertaken, first to define the areas contaminated by heavy metals (Zn, Cu, Co, Cr and V), and second to caracterize the different mineral phases, which trap these elements. Sediment samples were collected on twenty-eight stations scattered all over the lagoon, and each core (30 cm) was subdivided in two horizons (surface and depth). Mineralogical analyses as well as major and trace elements analyses were performed on surface and deep sediments. The results on major element analyses (Si, Al, Ca, Mg, Na, P) show an enrichment in halite and phosphates in the surface sediments. This highlights on one hand, low water exchange rates between the lagoon and the Mediterranean sea, and on the other hand, an increase in organic releases related to the urban, agricultural and fishery activities. The highest concentrations in inorganic micro-pollutant were recorded N-E of the lagoon and close to Nador city. With reference to the geochemical background, it can be concluded that there is a slight contamination in heavy metals. Moreover, enrichment factor calculations (EF) for heavy metals point out an increase in metal elements as following: Zn>Co>Cr>V>Cu. Sequential extractions were performed to determine the behaviour of these micro-pollutants. Thus, it was shown that carbonates, oxides and phosphates are the preferential mineral phases for trapping these heavy metals.

    Origanum compactum L. (Lamiaceae) is one of the most important medicinal species in term of ethnobotany in Morocco. It is considered as a very threatened species as it is heavily exploited. Its domestication remains the most efficient way to safeguard it for future generations. For this purpose, wide evaluation of the existing variability in all over the Moroccan territory is required. The essential oils of 527 individual plants belonging to 88 populations collected from the whole distribution area of the species in Morocco were analyzed by GC/MS. The dominant constituents were carvacrol (0 - 96.3%), thymol (0 - 80.7%), p-cymene (0.2 - 58.6%), γ-terpinene (0 - 35.2%), carvacryl methyl ether (0 - 36.2%), and α-terpineol (0 - 25.8%). While in the Middle Atlas region and the Central Morocco mainly carvacrol type samples were found, much higher chemotypic diversity was encountered within samples from the north part of Morocco (occidental and central Rif regions). The high chemical polymorphism of plants offers a wide range for selection of valuable chemotypes, as a part of breeding and domestication programs of this threatened species.

    Understanding past human-climate-environment interactions is essential for assessing the vulnerability of landscapes and ecosystems to future climate change. This is particularly important in southern Morocco where the current vegetation is impacted by pastoralism, and the region is highly sensitive to climate variability. Here, we present a 2000-year record of vegetation, sedimentation rate, XRF chemical element intensities, and particle size from two decadal-resolved, marine sediment cores, raised from offshore Cape Ghir, southern Morocco. The results show that between 650 and 850 AD the sedimentation rate increased dramatically from 100 cm/1000 years to 300 cm/1000 years, and the Fe/Ca and pollen flux doubled, together indicating higher inputs of terrestrial sediment. Particle size measurements and end-member modelling suggest increased fluvial transport of the sediment. Beginning at 650 AD pollen levels from Cichorioideae species show a sharp rise from 10% to 20%. Pollen from Atemisia and Plantago, also increase from this time. Deciduous oak pollen percentages show a decline, whereas those of evergreen oak barely change. The abrupt increase in terrestrial/fluvial input from 650 to 850 AD occurs, within the age uncertainty, of the arrival of Islam (Islamisation) in Morocco at around 700 AD. Historical evidence suggests Islamisation led to population increase and development of southern Morocco, including expanded pastoralism, deforestation and agriculture. Livestock pressure may have changed the vegetation structure, accounting for the increase in pollen from Cichorioideae, Plantago, and Artemisia, which include many weedy species. Goats in particular may have played a dominant role as agents of erosion, and intense browsing may have led to the decline in deciduous oak; evergreen oak is more likely to survive as it re-sprouts more vigorously after browsing. From 850 AD to present sedimentation rates, Fe/Ca ratios and fluvial discharge remain stable, whereas

  17. Preliminary Investigations on the Distribution of Leptospira Serovars in Domestic Animals in North-west Morocco.

    Leptospirosis is a neglected zoonosis of global importance with a complex epidemiology that affects humans, domestic and wild mammals. However, due to the diversity of clinical signs and difficulties of establishing a confirmatory laboratory diagnosis, the disease remains poorly investigated, particularly in the developing world. In Morocco, a descriptive study of the seroprevalence of Leptospira infection in animals has never been undertaken. To fill this gap, the current study was conducted on a subset of animals in north-west Morocco as a preliminary step towards understanding the epidemiological patterns of animal leptospirosis in the country. The study was conducted on 289 serum samples collected between January and April 2012 from dogs, cattle, sheep, goats and donkeys in the areas of Rabat-Temara, Sidi Kacem and Oulmes. All serum samples were tested by the MAT with 14 reference strains of the most prevalent pathogenic serovars of Leptospira and two serovars of non-pathogenic Leptospira. The overall seroprevalence of Leptospira in cattle, sheep, goats, dogs and donkeys was 15%, 18%, 20%, 21% and 20%, respectively. The most prevalent serogroups found in each species were Ballum, Sejroe, and Australis in cattle, Ballum, Australis and Sejroe in sheep, Australis and Ballum in goats, Javanica and Australis in donkey and Australis, Ballum and Canicola in dogs. Of all the serogroups tested in this study, Icterohaemorrhagiae, the only serogroup which has been previously reported in humans in Morocco, was rarely reactive. The majority of reactive sera were collected from low land areas. A large number of sera samples classified as seronegative when tested against pathogenic leptospires were positive when tested against non-pathogenic leptospires; this is suggestive of possible novel, as yet unclassified, Leptospira serovars in Morocco. Eleven of thirteen sheep urine samples were positive by real-time PCR confirming their role as Leptospira carriers in Morocco.

  18. The added value of water footprint assessment for national water policy: a case study for Morocco.

    2014-01-01

    A Water Footprint Assessment is carried out for Morocco, mapping the water footprint of different activities at river basin and monthly scale, distinguishing between surface- and groundwater. The paper aims to demonstrate the added value of detailed analysis of the human water footprint within a country and thorough assessment of the virtual water flows leaving and entering a country for formulating national water policy. Green, blue and grey water footprint estimates and virtual water flows are mainly derived from a previous grid-based (5 × 5 arc minute) global study for the period 1996-2005. These estimates are placed in the context of monthly natural runoff and waste assimilation capacity per river basin derived from Moroccan data sources. The study finds that: (i) evaporation from storage reservoirs is the second largest form of blue water consumption in Morocco, after irrigated crop production; (ii) Morocco's water and land resources are mainly used to produce relatively low-value (in US$/m3 and US$/ha) crops such as cereals, olives and almonds; (iii) most of the virtual water export from Morocco relates to the export of products with a relatively low economic water productivity (in US$/m3); (iv) blue water scarcity on a monthly scale is severe in all river basins and pressure on groundwater resources by abstractions and nitrate pollution is considerable in most basins; (v) the estimated potential water savings by partial relocation of crops to basins where they consume less water and by reducing water footprints of crops down to benchmark levels are significant compared to demand reducing and supply increasing measures considered in Morocco's national water strategy.

    Cervical cancer is a major public health concern in Morocco where it represents the second most common and lethal cancer in women. Human papillomavirus (HPV) vaccines have been licensed in Morocco since 2008 but there are no available data on their acceptability. This study aimed to assess awareness of HPV and the vaccine, and to identify factors associated with acceptability of the vaccine among parents in Morocco. We carried out a questionnaire-based survey using face-to-face interviews in a sample of 852 parents (670 mothers and 182 fathers) with at least one unmarried daughter ≤26 years. We collected data within public and private health centres and clinics in four regions in Morocco between July and August 2012. The main outcome measure was parental acceptability of the HPV vaccine for their daughter(s). Responses revealed very low awareness of HPV infection (4.7%) and the HPV vaccine (14.3%). None of the participants had vaccinated their daughter(s) against HPV and vaccine acceptability was low among mothers (32%) and fathers (45%). Higher education and income, previous awareness of the HPV vaccine and endorsement of the belief that a recommendation from the Ministry of Health or a doctor to have the vaccine would be encouraging, were associated with mothers' HPV vaccine acceptability. Non-acceptability among mothers was associated with having more than two daughters, believing the vaccine was expensive, lack of information and believing that whatever happens to an individual's health is God's will. The only factor associated with the fathers' acceptability of the vaccine was the cost of the vaccine. Increasing HPV and HPV vaccine awareness through educational campaigns, along with active recommendation by physicians and a publically funded vaccination programme could increase parental acceptability of the HPV vaccine in Morocco.

    Background Medicinal plant trade is important for local livelihoods. However, many medicinal plants are difficult to identify when they are sold as roots, powders or bark. DNA barcoding involves using a short, agreed-upon region of a genome as a unique identifier for species– ideally, as a global standard. Research Question What is the functionality, efficacy and accuracy of the use of barcoding for identifying root material, using medicinal plant roots sold by herbalists in Marrakech, Morocco, as a test dataset. Methodology In total, 111 root samples were sequenced for four proposed barcode regions rpoC1, psbA-trnH, matK and ITS. Sequences were searched against a tailored reference database of Moroccan medicinal plants and their closest relatives using BLAST and Blastclust, and through inference of RAxML phylograms of the aligned market and reference samples. Principal Findings Sequencing success was high for rpoC1, psbA-trnH, and ITS, but low for matK. Searches using rpoC1 alone resulted in a number of ambiguous identifications, indicating insufficient DNA variation for accurate species-level identification. Combining rpoC1, psbA-trnH and ITS allowed the majority of the market samples to be identified to genus level. For a minority of the market samples, the barcoding identification differed significantly from previous hypotheses based on the vernacular names. Conclusions/Significance Endemic plant species are commercialized in Marrakech. Adulteration is common and this may indicate that the products are becoming locally endangered. Nevertheless the majority of the traded roots belong to species that are common and not known to be endangered. A significant conclusion from our results is that unknown samples are more difficult to identify than earlier suggested, especially if the reference sequences were obtained from different populations. A global barcoding database should therefore contain sequences from different populations of the same species to assure the

    Two controlled-source wide angle seismic reflection experiments have been acquired recently (2010 and 2011) in northern Africa across Morocco. A lithospheric scale transect can be constructed by joining both data sets. Hence, an approximately 700 km-long seismic velocity cross section can be derived. From south-to-north the transect goes from the Sahara Platform, south of Merzouga, to Tanger in the north. The first experiment, SIMA, aimed to constrain the crustal structure across the Atlas Mountains. The Rif, the orogenic belt located just south of the coast of Alboran Sea, was the target of the second experiment, RIFSIS. In both cases 900 recording instruments (TEXANS) from the IRIS-PASSCAL instrument center were used to record the acoustic energy generated by explosion shots. In both experiments the shots consisted of 1 TM of explosives fired in ~30 m deep boreholes. Although the data quality varies from shot to shot, key seismic phases as Pg, PmP, Pn, and a few intra-crustal arrivals have been identified to constrain the velocity-depth structure along the whole transect. Forward modelling of the seismic reflection/refraction phases reveals a crust consisting of 3 layers in average. The Moho topography shows from south to north a relatively moderate crustal root beneath the High Atlas, which can reach 40-42 km depth. The crust is thicker beneath the Rif where the Moho is imaged as an asymmetric feature that locally defines a crustal root reaching depths of 50 km and suggesting a crustal imbrication. P wave velocities are rather low in the crust and upper mantle. First arrivals/reflections tomography supports the forward modelling results. Low fold wide-angle stacks obtained by using hyperbolic move-out reveals the geometry of the Moho along the entire transect. Beneath the Atlas, the moderate crustal root inferred is not isostatically consistent with the high surface elevations, hence supporting the idea of a 'mantle plume' as main contributor to the Atlas

    As a manifestation of the epidemiologic transition being experienced throughout the developing world, the prevalence of diabetes mellitus (DM) is increasing. However, whether an individual's risk of cardiovascular diseases as a consequence of DM is also higher in these countries is unknown. We conducted a case-control study at the medical center in the state of Qatar comparing the prevalence of DM in 512 patients who were admitted with acute myocardial infarctions (MI) and 262 cases of cerebrovascular accidents (CVA) to 382 hospital and outpatient controls to calculate the odds ratios (OR) associated with DM for MI and CVA. The OR for MI was estimated to be 4.01 compared to 2.92 for other countries in the Middle East and 1.75 for North America. The OR was even higher for Qatari natives. Understanding the reasons for this increase, including genetic differences, lifestyle, and medical management issues, is critical for the design and prioritization of effective interventions.

    Oil and gas as the non-renewable resources are considered very valuable for the countries with petroleum economics. These resources are not only diffused equally around the world, but also they are common in some places which their neighbors often come into conflicts. Consequently, it is vital for those countries to manage their resource utilization. Lately, game theory was applied in conflict resolution of common resources, such as water, which is a proof of its efficacy and capability. This paper models the conflicts between Iran and its neighbors namely Qatar and Iraq between their oil and gas common resources using game theory approach. In other words, the future of these countries will be introduced and analyzed by some well-known 2 × 2 games to achieve a better perspective of their conflicts. Because of information inadequacy of the players, in addition to Nash Stability, various solution concepts are used based on the foresight, disimprovements, and knowledge of preferences. The results of mathematical models show how the countries could take a reasonable strategy to exploit their common resources.

    Recently, extensive R&D has been conducted, both by industry and academia, to significantly raise the conversion efficiency of commercial photovoltaic (PV) modules. The installation of PV systems aimed at optimizing solar energy yield is primarily dictated by its geographic location and installation design to maximize solar exposure. However, even when these characteristics have been addressed appropriately, there are other factors that adversely affect the performance of PV systems, namely the temperature-induced voltage decrease leading to a PV power loss, and the dust accumulation (soiling). The latter is the lesser acknowledged factor that significantly influences the performance of PV installations especially in the Middle East region. In this paper we report on the investigation of the structural and physical properties of the desert-dust particles in the State of Qatar. The dust particles were collected directly from the PV panels installed in desert environment and characterized by different techniques, including scanning electron, optical and atomic force microscopies, X-ray diffraction, energy-dispersive, UV-Vis, micro-Raman and Fourier transform infrared spectroscopy. The vibrating sample magnetometry analyses were also conducted to study the magnetic properties of the dust particles. The influence of the dust accumulation on the PV panel performance was also presented and discussed. PMID:27526667

    The use of strontium-isotope ratios of dolomites to constrain timing and mechanism of diagenesis has been investigated on Jurassic Arab IV dolomites from offshore Qatar. Reservoir quality is determined by two types of dolomites, which were differentiated geochemically (cathodoluminescence, fluid inclusions, and carbon and oxygen stable isotopes): (1) stratigraphically concordant sucrosic dolomites with high porosity formed during early near-surface diagenesis (Jurassic) and (2) stratigraphically discordant cylindrical bodies of massive, porosity-destroying dolomites formed late during deep burial diagenesis (Eocene-Pliocene). Detailed Sr-isotope analysis of dolomites from the Arab IV confirms an Early Jurassic age of the sucrosic, high porosity dolomites ({sup 87}Sr/{sup 86}SR = 0.70707 for NBS 987 = 0.71024) with magnesium and strontium being derived from Jurassic seawater. Late Tertiary compressional orogeny of the Zagros belt to the north is proposed to have caused large-scale squeezing of fluids from the pore system of sedimentary rocks. A regional deep fluid flow system developed dissolving infra-Cambrian evaporites upflow and causing large-scale deep burial dolomitization downflow.

    Colony-forming eutrophic marine microorganisms in ballast water were counted in samples taken on board in 2002 and 2003. In the ballast water in Japan, viable cell numbers were highly variable but not by more than 10(5.1) colony-forming units (CFU)ml(-1) regardless of season. Even when ballast water was discharged offshore, values varied but not by more than 10(5.0) CFUml(-1). The effectiveness of the ballast water exchange was unconfirmed, except for the February 2003 voyage. No microbial colonies were counted in the reloaded ballast water in the high seas on that voyage, which contributed to the reduction of the total number of viable cells sampled in the discharged ballast water at the Ras Laffan port in Qatar. In sediment samples, the values of 10(5.2) - 10(6.0) CFUml(-1) were estimated for all seasons in which voyages took place. The maximum of the marine Vibrio species, 110 CFUml(-1), was observed in the ballast water sample taken in July 2003. The estimated total viable cell numbers in sediments were higher than those counted in the ballast water throughout the experiments, indicating the importance of sediment management as well as ballast water management on vessels traveling from Japan.

    The burgeoning immigrant population in major immigrant-receiving countries in North America and Europe has necessitated researchers and policymakers in these countries to examine the academic success of children of immigration and the factors contributing to their academic success. However, there is sparse research on the academic trajectories of children of immigration in other continents, such as Asia. Hence, the purpose of the present study was to examine first- and second-generation immigrant adolescents' mathematics achievement and dispositions towards mathematics in comparison to their native peers in one of the Middle Eastern countries in Asia, Qatar. The results of the study indicated that both first- and second-generation immigrant adolescents tended to have higher mathematics achievement, intrinsic motivation to learn mathematics, instrumental motivation to learn mathematics, mathematics self-efficacy, and mathematics self-concept than did their native counterparts. Moreover, immigrant adolescents tended to have lower mathematics anxiety than did their native peers. The study also revealed significant differences between first- and second-generation immigrant adolescents with respect to their mathematics achievement and dispositions towards mathematics.

    Antibodies to Middle East respiratory syndrome coronavirus (MERS-CoV) were detected in serum and milk collected according to local customs from 33 camels in Qatar, April 2014. At one location, evidence for active virus shedding in nasal secretions and/or faeces was observed for 7/12 camels; viral RNA was detected in milk of five of these seven camels. The presence of MERS-CoV RNA in milk of camels actively shedding the virus warrants measures to prevent putative food-borne transmission of MERS-CoV.

    believed that IM would cure the disease. The MPR results reveal that 16% of patients had poor access to treatment through the hospital pharmacy. DISCUSSION AND CONCLUSION This is the first prospective study to evaluate CML patients’ adherence and response to IM in Qatar. The high rate of treatment failure observed in Qatar is explained by poor adherence. An economic factor (unaffordable drug prices) is one of the main causes of nonadherence and efforts should be made locally to improve access to medication for cancer diseases. Other risk factors associated with poor adherence could be improved by close monitoring and dose adjustment. Monitoring risk factors for poor adherence and patient education that include direct communication between the health-care teams, doctors, nurses, pharmacists, and patients are essential components for maximizing the benefits of TKI therapy and could rectify this problem. The preliminary results show that patients’ response to treatment may be directly linked to patients’ adherence to treatment. However, further in-depth and specific analysis may be necessary in a larger cohort. PMID:27721664

    Self-governance and responsibility are two traits associated with neoliberal citizenship in scholarly and popular discourses, but little of the literature on this topic focuses on North Africa. My goal, in this article, is not only to fill this void but also to complicate understandings of neoliberalism through an examination of the relationship between reproductive health care, development policy, and popular Islamic beliefs in Morocco. My discussion is based on fieldwork in Rabat, Morocco, which included observations in health clinics, interviews with patients and staff, and visits to patients' homes. By analyzing the childbearing and childrearing practices of Moroccan women who visited the clinics, I pose that neoliberal logic cannot be predefined or understood as a monolithic concept. I demonstrate that women were active in their own governance and accountable for their reproductive behaviors, but they did so because of their understandings of what Islam says about fertility and motherhood.

    A new species of fairy shrimp, Linderiella jebalae sp. nov., was found in temporary ponds located in the Rif region of northern Morocco. Morphological characters of females, such as the basal long warty outgrowth of the antennae, the highly developed cuticular papillae in the second genital segment, and the presence of a keel-shaped process directed posteriorly in dorsal side of the brood pouch, clearly distinguish this species from the others of the genus. In the case of males, the basiomedial antennal outgrowth and the distal segment of the antenna are diagnostic features for the species. Cyst ornamentation, characterized by thick, blunt and sometimes truncated spines, also separate this species. This is the fourth known Palaearctic Linderiella species, all of them described recently (from 1980s onwards) and located in a restricted area, from south-eastern France to Iberian Peninsula and Morocco.

    Severe combined immunodeficiency disease (SCID) of horses is an autosomal, recessive hereditary disease occurring among Arabian or crossbred Arabian horses. The genetic defect responsible was previously identified as a 5-base pair deletion in the gene encoding the catalytic subunit of the DNA dependant protein kinase (DNA-PKcs). This study was carried out to determine the frequency of SCID and identify horses carrying the gene for SCID among Arabian and Arabian crossbred stallions and mares in Morocco using a DNA-based test. Twenty-one horses were SCID carriers: 14 (7%) Arabians, 6 (4%) Arab-Barbs and one (33%) Anglo-Arab. After analysing their genealogy, 3 imported stallions were identified that disseminated the mutant gene of DNA-PKcs in Morocco.

    The Stratocumulus cloud formation is very common in the Canary Islands (Spain) and on the Atlantic coast of Morocco. This cloud formation behaves as if it was fog when it comes into contact with the relief and its liquid content can be captured by artificial systems. The origin of this cloud formation is connected with the Azores anti-cyclone and with the anomalous structure of the low layers of the atmosphere caused by a subsidence thermal inversion. The aim of this article is to define a pattern of the most favourable meteorological and atmospheric conditions for this cloud formation to appear. In order to do this, a database has been compiled with the information about the days on which water has been collected in Morocco since June, 2006. This was when the collaboration with the Si Hmad Derhem Foundation (Casablanca) began. As well as meteorological data and data on water quantities, weather maps, thermodynamic soundings and satellite images are also analysed. The following two sites were studied: Anaga, on the island of Tenerife, Canary Islands, 864 m a.s.l. and 4 km from the coast, and Boutmezguida, Morocco, 1,225 m a.s.l. and 30 km from the coast. The research was conducted in three stages. The first stage consisted of looking for the most appropriate sites to obtain the greatest efficiency in fog water collection; the Standard Fog Collector (SFC, Schemenauer and Cereceda, 1994) was used for this purpose. The second stage consisted of studying the most favourable meteorological conditions for water collection where the Quarter Fog Collector (QFC, Marzol, 2002) connected to an automatic weather station providing information on temperature, humidity, precipitation, wind speed and direction and the amount of water collected on the netting every ten minutes was used to do this. The aim of the third stage, which was by nature an applied stage, was to construct large-sized fog collectors (Large Fog Collector, LFC) so that the water collected could be put to

    The dynamics underlying cereal crops in the northern region of Morocco is investigated using a global modelling technique applied to a vegetation index time series derived from satellite measurements, namely, the normalized difference vegetation index from 1982 to 2008. Two three-dimensional chaotic global models of reduced size (14-term and 15-term models) are obtained. The model validation is performed by comparing their horizons of predictability with those provided in previous studies. The attractors produced by the two global models have a complex foliated structure-evidenced in a Poincaré section-rending a topological characterization difficult to perform. Thus, the Kaplan-Yorke dimension is estimated from the synthetic data produced by our global models. Our results suggest that cereal crops in the northern Morocco are governed by a weakly dissipative three-dimensional chaotic dynamics.

    Egypt has the highest prevalence of recorded hepatitis C virus (HCV) worldwide, estimated nationally at 14.7%, which is attributed to extensive iatrogenic transmission during the era of parenteral antischistosomal therapy (PAT) mass-treatment campaigns. The objective of our study was to attempt to highlight to what extent HCV transmission is ongoing and discuss the possible risk factors. We studied the prevalence of HCV among 7.8% of Egyptians resident in Qatar in relation to age, socioeconomic status, and PAT and discuss the possible risk factors. HCV testing was conducted in 2,335 participants, and results were positive for 13.5%, and 8.5% for those aged below 35 years. The prevalence of HCV in the PAT-positive population was 23.7% (123 of 518, 95% confidence interval [CI] 20.2%-27.6%) compared with 11.2% in the PAT-negative group. Significantly higher HCV prevalence occurred in participants who were older than 50 years (23%, 95% CI 19.3%-27.1%) compared to those aged 45-50 years (19.3%, 95% CI 15.2%-23.8%), 35-45 years (11.1%, 95% CI 8.9%-13.7%), and less than 35 years (8.5%, 95% CI 6.8%-10.4%) (P<0.0001). Insignificant higher prevalence occurred in the low socioeconomic group (14.2%, 95% CI 11.3%-17.4%). Logistic regression analysis revealed that increasing age, history of PAT, bilharziasis, and praziquantel were common risk factors, but there was no relation with dental care. Host genetic predisposition seems to be a plausible underlying factor for susceptibility among Egyptians and intense ongoing infection.

    Background Screening for hepatitis C has been found to be beneficial in high-risk individuals and ‘baby boomers’. Objective Our aim was to screen for hepatitis C in average and high-risk individuals and compare the disease characteristics and response to treatment among the screened group (SG) and non-screened group (NSG). Method Community-based screening for hepatitis C was done in the average and high-risk populations of Qatar. Screening was done using rapid point-of-care testing. All patients with stage 1 fibrosis on liver biopsy were treated with pegylated interferon and ribavirin. Results In total, 13,704 people were screened and 272 (2%, 95% CI (1.8–2.2%) had positive antibodies to hepatitis C. During the same period, 237 non-screened patients (NSG) with hepatitis C were referred for treatment. Alanine and aspartate aminotransferases (ALT, AST) and overall fibrosis were significantly lower in the SG as compared with the NSG (p = 0.04, 0.04 and 0.01, respectively). The response to treatment was similar in the SG as compared with the NSG (sustained viral response 61.7 % versus 69.1%, p = 0.55). Average-risk patients had significantly lower ALT levels (p = 0.04) but had similar response to treatment as the high-risk individuals (sustained viral response 63.2 % versus 61%, p = 0.87). Conclusion Screening detects hepatitis C with lesser fibrosis but does not result in better response to pegylated interferon and ribavirin as compared with non-screened patients. PMID:26279845

    The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the four main layers (L1-L4) in the photosynthetic mats. Chlorophyll a (Chl a) concentration and distribution (measured by HPLC and hyperspectral imaging, respectively), the phycocyanin distribution (scanned with hyperspectral imaging), oxygenic photosynthesis (determined by microsensor), and the abundance of photosynthetic microorganisms (from 16S and 18S rRNA sequencing) decreased with depth in the euphotic layer (L1). Incident irradiance exponentially attenuated in the same zone reaching 1% at 1.7-mm depth. Proteobacteria dominated all layers of the mat (24%-42% of the identified bacteria). Anoxygenic photosynthetic bacteria (dominated by Chloroflexus) were most abundant in the third red layer of the mat (L3), evidenced by the spectral signature of Bacteriochlorophyll as well as by sequencing. The deep, black layer (L4) was dominated by sulfate reducing bacteria belonging to the Deltaproteobacteria, which were responsible for high sulfate reduction rates (measured using 35S tracer). Members of Halobacteria were the dominant Archaea in all layers of the mat (92%-97%), whereas Nematodes were the main Eukaryotes (up to 87%). Primary productivity rates of Um Alhool mat were similar to those of other hypersaline microbial mats. However, sulfate reduction rates were relatively low, indicating that oxygenic respiration contributes more to organic material degradation than sulfate reduction, because of bioturbation. Although Um Alhool hypersaline mat is a nutrient-limited ecosystem, it is interestingly dynamic and phylogenetically highly diverse. All its components work in a highly efficient and synchronized way to compensate for the lack of nutrient supply provided during regular inundation periods.

    Background Breastfeeding is considered as gold standard for infant nutrition and should be interrupted only when a compelling indication exists. Certain medical conditions such as abortion, stillbirth, HIV infection, or infant galactosemia and certain medications such as chemotherapy necessitate lactation inhibition to protect the health of mother and infant. Drug use evaluation (DUE) studies are done to explore the current practice in a setting and help to identify areas in which further information and education may be needed by clinicians. Objective The aim of this study was to conduct a DUE of cabergoline to assess indications for lactation inhibition, dosage regimen, and its safety. Method A retrospective cross-sectional DUE study was conducted over a period of 4 months from September 1, 2013, till December 31, 2013, at the Women’s Hospital, Qatar. All cabergoline prescriptions written for lactation inhibition within 10 days of delivery or abortion were included in the study. A descriptive data analysis was undertaken. Results Of the 85 patients included, stillbirth (50.6%) was considered as the main reason for lactation inhibition, followed by abortion (27.1%) and neonatal death (12.9%). The remaining 9.4% of the patients had live baby, and the majority of them were prescribed cabergoline for lactation inhibition because their maternal medical conditions required the use of drugs with insufficient safety data (n=6). Seventy-four percent of patients received cabergoline at accurate time and dose. However, 14% of the patients had preexisting hypertensive disorder and 58.3% of them were diagnosed as uncontrolled hypertension. Conclusion The current DUE study found that cabergoline was mainly used to inhibit lactation for patients with stillbirth, abortion, and neonatal death. In mothers who use medications for other medical conditions, benefits and risks of breastfeeding should be carefully balanced before prescribing cabergoline. Current prescribing pattern

    The occurrence of chlorine dioxide (ClO2) disinfection by-products (DBPs) in drinking water, namely, chlorite, chlorate, and trihalomethanes (THMs), was investigated. Two-hundred-ninety-four drinking water samples were collected from seven desalination plants (DPs), four reservoirs (R), and eight mosques (M) distributed within various locations in southern and northern Qatar. The ClO2 concentration levels ranged from 0.38 to <0.02 mg L(-1), with mean values of 0.17, 0.12, and 0.04 mg L(-1) for the DPs, Rs, and Ms, respectively. The chlorite levels varied from 13 μg L(-1) to 440 μg L(-1), with median values varying from 13 to 230 μg L(-1), 77-320 μg L(-1), and 85-440 μg L(-1) for the DPs, Rs, and Ms, respectively. The chlorate levels varied from 11 μg L(-1) to 280 μg L(-1), with mean values varying from 36 to 280 μg L(-1), 11-200 μg L(-1), and 11-150 μg L(-1) in the DPs, Rs, and Ms, respectively. The average concentration of THMs was 5 μg L(-1), and the maximum value reached 77 μg L(-1) However, all of the DBP concentrations fell within the range of the regulatory limits set by GSO 149/2009, the World Health Organization (WHO), and Kahramaa (KM).

    Objectives Depression is associated with increased morbidity and mortality rates among cardiovascular patients. Depressed patients have three times higher risk of death than those who are not. We sought to determine the presence of depressive symptoms, and whether gender and age are associated with depression among Arab patients hospitalised with cardiac conditions in a Middle Eastern country. Setting Using a non-probability convenient sampling technique, a cross-sectional survey was conducted with 1000 Arab patients ≥20 years who were admitted to cardiology units between 2013 and 2014 at the Heart Hospital in Qatar. Patients were interviewed 3 days after admission following the cardiac event. Surveys included demographic and clinical characteristics, and the Arabic version of the Beck Depression Inventory Second Edition (BDI-II). Depression was assessed by BDI-II clinical classification scale. Results 15% of the patients had mild mood disturbance and 5% had symptoms of clinical depression. Twice as many females than males suffered from mild mood disturbance and clinical depression symptoms, the majority of females were in the age group 50 years and above, whereas males were in the age group 40–49 years. χ2 Tests and multivariate logistic regression analyses indicated that gender and age were statistically significantly related to depression (p<0.001 for all). Conclusions Older Arab women are more likely to develop mood disturbance and depression after being hospitalised with acute cardiac condition. Gender and age differences approach, and routine screening for depression should be conducted with all cardiovascular patients, especially for females in the older age groups. Mental health counselling should be available for all cardiovascular patients who exhibit depressive symptoms. PMID:27388362

    Antimicrobial-resistant non-typhoidal Salmonella (NTS) are an important cause of infection in Africa, but there is a lack of information on their molecular mechanisms of resistance and epidemiology. This study contributes to fill this gap through the characterization by pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), plasmid profiling and analysis of antibiotic-resistance determinants of 94 Salmonella enterica strains isolated from food in Morocco. PFGE revealed considerable heterogeneity among the strains, showing 32 pulsotypes. MLST of strains representative of the different serovars evidenced 13 sequence types (STs), three of which were newly identified (ST1694, ST1768 and ST1818) and nine not previously reported in Morocco. Thirty-four strains harbored from one to four plasmids, of IncI1 group in S. Mbandaka, IncFIIA in S. Typhimurium, IncL/M in S. Hadar and S. Blockley. For the first time in Morocco an intact Salmonella Genomic Island 1 (SGI1) carrying the resistance genes aadA2, floR, tetG, blaPSE-1 and sul1 was detected in S. Typhimurium DT104. In serovar Hadar resistance to ampicillin, tetracycline and streptomycin was associated to blaTEM-1, tetA and strA genes respectively, whereas one mutation in gyrA (Asp87Asn) and one in parC (Thr54Ser) genes conferred resistance to nalidixic acid. These findings improve the information on foodborne Salmonella in Morocco, evidencing the presence of MDR strains potentially dangerous to humans, and provide useful data for future studies.

    The Mhorr gazelle (Gazella dama mhorr) became extinct in the wild in the 1960s. The current world zoo population amounts to some 240 animals, going back to only 12 founders. In a cooperate international operation Mhorr gazelles of European zoo populations were successfully reintroduced to national parks and nature reserves in Morocco and Tunisia in the years 1990/1992. The genetical and ecological prerequisites as well as the breeding aspects are discussed.

  8. Imaging Canary Island hotspot material beneath the lithosphere of Morocco and southern Spain

    The westernmost Mediterranean has developed into its present day tectonic configuration as a result of complex interactions between late stage subduction of the Neo-Tethys Ocean, continental collision of Africa and Eurasia, and the Canary Island mantle plume. This study utilizes S receiver functions (SRFs) from over 360 broadband seismic stations to seismically image the lithosphere and uppermost mantle from southern Spain through Morocco and the Canary Islands. The lithospheric thickness ranges from ∼65 km beneath the Atlas Mountains and the active volcanic islands to over ∼210 km beneath the cratonic lithosphere in southern Morocco. The common conversion point (CCP) volume of the SRFs indicates that thinned lithosphere extends from beneath the Canary Islands offshore southwestern Morocco, to beneath the continental lithosphere of the Atlas Mountains, and then thickens abruptly at the West African craton. Beneath thin lithosphere between the Canary hot spot and southern Spain, including below the Atlas Mountains and the Alboran Sea, there are distinct pockets of low velocity material, as inferred from high amplitude positive, sub-lithospheric conversions in the SRFs. These regions of low seismic velocity at the base of the lithosphere extend beneath the areas of Pliocene-Quaternary magmatism, which has been linked to a Canary hotspot source via geochemical signatures. However, we find that this volume of low velocity material is discontinuous along strike and occurs only in areas of recent volcanism and where asthenospheric mantle flow is identified with shear wave splitting analyses. We propose that the low velocity structure beneath the lithosphere is material flowing sub-horizontally northeastwards beneath Morocco from the tilted Canary Island plume, and the small, localized volcanoes are the result of small-scale upwellings from this material.

    The GM immunoglobulin allotype polymorphism was investigated in four Moroccan populations: three Berber groups from Khenifra (Middle Atlas), Amizmiz (High Atlas), and Bouhria (Beni Snassen) and one Arabic-speaking sample from the Doukkala area (Abda, Chaouia, Doukkali, and Tadla districts in south-central Morocco). In order to characterize the genetic relationships between the populations, our results were compared with those obtained for other North African groups (from Morocco, Algeria, Tunisia, and Niger) and for Middle-East Africans, sub-Saharans, and Southwest Europeans. Based on GM haplotype frequencies, Factorial Correspondence Analyses, F(ST) significance testing, and hierarchical analyses of variance were performed. Our results reveal that Moroccan populations have heterogeneous GM profiles with high frequencies of GM haplotypes in Europeans (from 76% for Doukkala to 88% for Bouhria) and relatively high frequencies of GM haplotypes in sub-Saharans (from 11% for Bouhria to 23% for Amizmiz). The genetic diversity observed among Moroccans is not significantly correlated with either geographic or linguistic differentiation. In spite of their cultural and historical differentiation, we did not discover any significant genetic differences between Berbers and Arabic-speakers from Morocco. However, when large geographical areas are considered, our population samples are integrated in the North African GM variation, significantly distant from sub-Saharan groups but with a close relationship with Southwest European populations.

  11. Cultural constructions of "obesity": understanding body size, social class and gender in Morocco.

    This article presents data from an in-depth qualitative study of overweight and diabetic women in Morocco, a North African country experiencing a rapid increase in obesity according to national statistics. This case study explores the heterogeneous relationship among health, culture and religion in Morocco by highlighting the relationship between the intricacies of women's everyday lives and their body sizes. My findings suggest that although the Body Mass Index (BMI) of adult women has been documented to have increased in Morocco along with other macroeconomic changes (i.e., increases in urbanization, etc.), "obesity" has yet to be universally medicalized in the Moroccan context. As such women do not generally utilize a medicalized concept of obesity in reference to their larger body sizes. Rather, cultural constructions of "obesity" are understood through cultural understandings of a larger body size, religious beliefs about health and illness, and the nature of women's religious participation. This stands in contrast to dominant accounts about the region that promote an overall veneration of a larger body size for women.

    We initiated GPS observations in Morocco during 1999 with the installation (May) and observation (October) of a 23-station network distributed throughout most of the country and extending from the Anti Atlas in central Morocco to the Rif Mountains along the Mediterranean coast. With UNAVCO assistance, we installed continuously recording, on-line GPS stations in Rabat (298, relocated 500), Tetouan (500), and Ifrane (701). We completed the first repeat observations of the network during February 2001. The resulting velocity estimates have uncertainties of about 3 mmyr E-W, and 2 mm/yr N-S (1 sigma, scaled). For the most part, the velocity determinations are within the uncertainties at the 95% confidence level. However, the preliminary velocities suggest N-S shortening between stations in the Rif Mountains and those in the Middle Atlas Mountains and the Anti Atlas. Furthermore, we see no clear evidence of significant northwestward motion of this part of the African plate (i.e., northwest Africa) relative to Eurasia, as is predicted by global plate models (Nuvel-1; 4.5 mmyr ~ NW). We are planning a repeat occupation of the survey network in October 2001. With three surveys over a two-year period, we should have substantially better constraints on present-day kinematics. We will present the results of this survey and discuss their implications for models of Africa plate motion and the active dynamics of Morocco and the Alboran Sea region.

    Sheep pox is endemic in most parts of Northern Africa and has the potential to cause severe economic problems. Live attenuated vaccines are used in Morocco, and in many other countries, to control the disease. Sheep pox virus (SPPV) re-appeared in 2010 causing a nodular clinical form previously not observed in Morocco. The severe clinical signs observed during the course of this outbreak and initial reports citing similarity in nucleotide sequence between the Moroccan vaccine strain and field isolates warranted a more in depth analysis of this epizootic. In this study, sequence analysis showed that isolates obtained from four provinces of eastern Morocco were identical, demonstrating that a single SPPV strain was responsible for the 2010 epizootic. In addition, the genome fragments sequenced and phylogenetic analyses undertaken as part of this study showed significant differences between field isolates and the Moroccan vaccine strain. New PCR methods were developed to differentiate between wild-type isolates and vaccine strains of SPPV. Using these methods, no trace of wild-type SPPV was found in the vaccine and no evidence was found to suggest that the vaccine strain was causing clinical disease.

    Malaria resurgence risk in Morocco depends, among other factors, on environmental changes as well as the introduction of parasite carriers. The aim of this paper is to analyze the receptivity of the Loukkos area, large wetlands in Northern Morocco, to quantify and to map malaria transmission risk in this region using biological and environmental data. This risk was assessed on entomological risk basis and was mapped using environmental markers derived from satellite imagery. Maps showing spatial and temporal variations of entomological risk for Plasmodium vivax and P. falciparum were produced. Results showed this risk to be highly seasonal and much higher in rice fields than in swamps. This risk is lower for Afrotropical P. falciparum strains because of the low infectivity of Anopheles labranchiae, principal malaria vector in Morocco. However, it is very high for P. vivax mainly during summer corresponding to the rice cultivation period. Although the entomological risk is high in Loukkos region, malaria resurgence risk remains very low, because of the low vulnerability of the area.

    Of the 12 or more sedimentary basins in Morocco, only three contain or have contained oil and gas production: the onshore Essaouira, Rharb, and Prerif basins. Large quantities of heavy oil and some light oil in place were also found in the Atlantic Tarfaya basin off Southwest Morocco, but these have been classified as noncommercial. Oil production has been established on the south flank of the Prerif foreland basin east of the Rharb basin; this production is now shut-in, as is gas and oil production in the Essaouria basin. As a result, no oil production exists today in Morocco, and only minor gas production and reserves in Neogene reservoirs exist in the Rharb basin. This situation is somewhat puzzling because thick, attractive sediments containing potential oil source beds, reservoirs, and traps are present in many of the basins, and oil and gas shows were present in many exploration wells across the country. The authors summarize here the known petroleum-geological parameters of the Prerif basin with the hope of raising some general exploration interest in this attractive new play region.

    The "Lisbon" earthquake of November 1, 1755, the effects of which have been described at length in the Iberian Peninsula, was likewise strongly felt in Morocco, especially on the Atlantic coast, which was laid waste not only through the direct agency of seismic waves, but also through that of a formidable tsunami. The study of these effects in Morocco, based on a critical analysis of European and Arab sources entailing, whenever possible, a consultation of the original sources, has lead to the hypothesis that two distinct destructive earthquakes would have followed the main shock of November 1; one, on November 18, 1755, was probably an aftershock of the November 1 event and originated in the Gorringe Bank; the other, on November 27, 1755, was located in the Meknes area and is supposed to have destroyed that town. The values of intensities interpreted from the observations of the November 1 event have been compared with the values derived from the attenuation laws obtained from the recent earthquake of February 28, 1969 originating at the same source, the Moroccan isoseismals of which are well established. Extrapolated isoseismals for the effects of the November 1, 1755 event in Morocco as derived from this study are then assigned

    Bensaid, M.; Mahmood, A.

    Preliminary results of a tectonlinear study of Landsat MSS images in bands, 4, 5 and 7 covering Middle Morocco are presented. The relationships between lineaments and large-scale structural patterns are studied and compared with geological and ore deposits distribution data on the area. Middle Morocco in this article comprises parts of the Moroccan Meseta, Central and Eastern High Atlas and northeastern Anti-Atlas. Rocks of all ages, from Precambrian to Quaternary, are found, and the structural evolution of the area is due to Precambrian, Variscan and Alpine orogenies. Two main lineament sets are recognized on the satellite images. These are NE-SW and NW-SE. The NW-SE set of lineaments is prominent in older Precambrian and Paleozoic terranes, whereas the NE-SW set is observed both in the old inliers and massifs as well as in the younger mountain chains. The NE-SW lineaments therefore represent reactivated fractures that should have played an important role in the tectonics and sedimentary cycles of Middle Morocco. Other lineament trends are seen only in specific regions of the study area. Several major ore deposits follow lineament trends both in the basement and cover rocks. This is particularly true of endogenic deposits in the Anti-Atlas and in the Central Paleozoic massif.

    413 (119 men, 294 women) undergraduate university students in Qatar completed an Arabic version of the Learning and Study Strategies Inventory (LASSI) measuring Anxiety, Attitude, Concentration, Information Processing, Motivation, Self-testing, Selecting Main Ideas, Study Aids, Time Management, and Test Strategies. The students' learning and study strategies scores were similar to those reported in the literature. Factor analysis indicated the same general factors as in the original study. Internal consistency estimates ranged from .62 to .88. Nine of the 10 scales (i.e., all with the exception of the Study Aids) significantly correlated with students' GPAs. Scores obtained from these scales provide valid assessments of Qatar University students' use of learning and study strategies related to skill, will, and self-regulation components of strategic learning and also academic achievement. There also were statistically significant differences between higher and lower achieving students in their learning and study strategies. This study also explored the use of the LASSI as a predictive measure of academic achievement. Anxiety and test strategies were significant predictors of academic achievement as measured by students' GPA.

    The goal of this study was to establish the first baseline measurements for radioactivity concentration of the artificial radionuclide 137Cs in soil samples collected from the Qatarian peninsula. The work focused on the determination of the activity concentrations levels of man-made radiation in 129 soil samples collected across the landscape of the State of Qatar. All the samples were collected before the most recent accident in Japan, “the 2011 Fukushima Dai-ichi nuclear power plant accident”. The activity concentrations have been measured via high-resolution gamma-ray spectrometry using a hyper-pure germanium detector situated in a low-background environment with a copper inner-plated passive lead shield. A radiological map showing the activity concentrations of 137Cs is presented in this work. The concentration wasfound to range from 0.21 to 15.41 Bq/kg. The highest activity concentration of 137Cs was observed in sample no. 26 in North of Qatar. The mean value was found to be around 2.15 ± 0.27 Bq/kg. These values lie within the expected range relative to the countries in the region. It is expected that this contamination is mainly due to the Chernobyl accident on 26 April 1986, but this conclusion cannot be confirmed because of the lack of data before this accident.

    Background: Misoprostol is a synthetic prostaglandin E1 that induces cervical effacement and uterine contractions at all gestational ages, thus facilitating uterine evacuation and pregnancy termination. Successful medical evacuation of spontaneous miscarriage with minimal adverse effects can be performed using misoprostol-only regimen if given as indicated and if the administered dose, frequency of the dosage, and number of total doses are appropriate. Aim: To conduct a drug use evaluation by investigating indications, appropriateness of dosing, and clinical outcome of misoprostol-only regimen when used for medical evacuation of spontaneous miscarriage at the Women's Hospital in Doha, Qatar. Materials and methods: A retrospective descriptive drug use evaluation was conducted on women with spontaneous miscarriage who received misoprostol for medical evacuation during August 2013. The current practice at the Women's Hospital was compared with the recommendation from the World Health Organization (WHO). Patients were stratified into three groups based on weeks of amenorrhea. Results: A total of 107 patients received misoprostol during August 2013, of which 33 (31%) were included in the study. In these patients, the main indication for misoprostol use was missed miscarriage (54.5%). In the group of patients at ≤ 9 weeks of gestation, 80% received an initial dose of 800 μg, 80% received frequency within the WHO recommendation, and the majority had surgical evacuation (80%). In the group of patients at 10–12 weeks of gestation, more than 80% received an initial dose of 800 μg, 6% received frequency within the WHO recommendation, and more than 75% had successful medical evacuation. In the group of patients at 13–22 weeks of gestation, more than 80% received an initial dose of 400 μg, more than 80% received frequency within the WHO recommendation, and 54% had successful medical evacuation. Overall, more than 70% of the patients received ≤ 3 total doses of

    Introduction Acute coronary syndrome (ACS) is one of the leading causes of morbidity and mortality worldwide. Secondary cardiovascular risk reduction therapy (consisting of an aspirin, a β-blocker, an ACE inhibitor or an angiotensin II receptor blocker and a statin) is needed for all patients with ACS. Less than 80% of patients with ACS in Qatar use this combination after discharge. This study is aimed to evaluate the effectiveness of clinical pharmacist-delivered intervention at discharge and tailored follow-up postdischarge on decreasing hospital readmissions, emergency department (ED) visits and mortality among patients with ACS. Methods and analysis A prospective, randomised controlled trial will be conducted at the Heart Hospital in Qatar. Patients are eligible for enrolment if they are at least 18 years of age and are discharged from any non-surgical cardiology service with ACS. Participants will be randomised into 1 of 3 arms: (1) ‘control’ arm which includes patients discharged during weekends or after hours; (2) ‘clinical pharmacist delivered usual care at discharge’ arm which includes patients receiving the usual care at discharge by clinical pharmacists; and (3) ‘clinical pharmacist-delivered structured intervention at discharge and tailored follow-up postdischarge’ arm which includes patients receiving intensive structured discharge interventions in addition to 2 follow-up sessions by intervention clinical pharmacists. Outcomes will be measured by blinded research assistants at 3, 6 and 12 months after discharge and will include: all-cause hospitalisations and cardiac-related hospital readmissions (primary outcome), all-cause mortality including cardiac-related mortality, ED visits including cardiac-related ED visits, adherence to medications and treatment burden. Percentage of readmissions between the 3 arms will be compared on intent-to-treat basis using χ2 test with Bonferroni's adjusted pairwise comparisons if needed. Ethics and

  3. Estimation of the cost of treatment by chemotherapy for early breast cancer in Morocco

    2010-01-01

    Background Breast cancer is the first cancer in women both in incidence and mortality. The treatment of breast cancer benefited from the progress of chemotherapy and targeted therapies, but there was a parallel increase in treatment costs. Despite a relatively high incidence of many sites of cancer, so far, there is no national register for this disease in Morocco. The main goal of this paper is to estimate the total cost of chemotherapy in the early stages of breast cancer due to its frequency and the chances of patients being cured. This study provides health decision-makers with a first estimate of costs and the opportunity to achieve the optimal use of available data to estimate the needs of antimitotics and trastuzumab in Morocco. Method We start by evaluating the individual cost according to the therapeutic sub-groups, namely: 1. Patients needing chemotherapy with only anthracycline-based therapy. 2. Patients needing chemotherapy with both anthracycline and taxane but without trastuzumab. 3. Patients needing trastuzumab in addition to chemotherapy. For each sub-group, the protocol of treatment is described, and the individual costs per unit, and for the whole cycle, are evaluated. Then we estimate the number of women suffering from breast cancer on the basis of two data bases available in Morocco. Finally, we calculate the total annual cost of treatment of breast cancer in Morocco. Results The total cost of breast cancer in Morocco is given in Moroccan dirhams (MAD), the US dollar at the current exchange rate (MAD 10 = USD 1.30) and in international dollars or purchasing power parity (MAD 10 = PPP 1.95). The cost of a therapy with trastuzumab is 8.4 times the cost of a sequential chemotherapy combining anthracycline and taxane, and nearly 60 times the cost of chemotherapy based on anthracycline alone. Globally, between USD 13.3 million and USD 28.6 million need to be devoted every year by the Moroccan health authorities to treat women with localized breast

    Two periods of geological research can be recognized in the Ediacaran and Cambrian of Morocco. The period 1917-1945 is represented by an exploration phase that led to numerous discoveries of Cambrian faunas overlying conformably or unconformably, thick, metamorphic, Precambrian formations. The Moroccan Geological Society (SGM) published numerous geological maps with notices and regional monographies. The second period (1948-1995) allowed erection of detailed litho- and biostratigraphic sketches for stratigraphic subdivisions, among which the proposal of alternative (radiometric and chemostratigraphic) methods to precisely locate the Precambrian-Cambrian boundary in Morocco.

    In Morocco, wheat production shows a high inter-annual variability due to uncertain rainfall. In view of the importance of this resource to the country's economy, it is important to gain a better understanding of the natural large-scale climate oscillation governing this variability. In this study, we analyzed de-trended (1) time series of common wheat yields (1983-2008) from 11 agricultural provinces that account for 80% of national wheat production; (2) monthly rainfall and 10-day temperature from ten meteorological stations; (3) 10-day normalized difference vegetation index (NDVI) from the AVHRR sensor; (4) monthly atmospheric climate indices [North Atlantic Oscillation (NAO) and Scandinavian Pattern (SCA)] and monthly 500 hPa geopotentials fields; and (5) monthly sea surface temperature (SST) fields and indices (NIÑO3, Tropical North Atlantic and Tropical South Atlantic). The relationship between rainfall and temperature during tillering in early winter and grain filling in early spring and wheat yields already observed at the plot scale was also found to be significant at the provincial scale. The linkages between wheat yields and large scale climate have been analyzed for the first time over Morocco. In agreement with previous studies, results show a complex and competing influence of different climate phenomena. The NAO is found to be significantly related to yields during the early stage of wheat growth in December, whereas the SCA correlates with yields later in the season, in January and February. Interesting lagged correlations with higher lead time are also highlighted, with the leading modes of SST variability in the equatorial Atlantic during October (the "Atlantic Niño" mode) and in the North Atlantic (the "Atlantic tripole" mode) in February. Our conclusion is that regional climate indices and variables represent valuable information with which to increase lead time and skill regarding wheat yield predictions in Morocco.

    Since the end of last century, qualified meteorological events of "exceptional" causing floods have ceased to occur in Morocco and elsewhere, with a recurrence increasingly high, prompting to wonder about the "new" mode of climate's hydrothermal functioning inducing torrential rains, as well as its effect on the environment and societies.The latest event is the disaster of November 2014 flooding in southern Morocco, which is due especially to the non usual rains return.Weather conditions were marked by enhanced Meridian Atmospheric Circulation (MAC), characterized by persistent high temperatures during the autumn period in Morocco, mainly south of the Atlas, combined by the intrusion of a cold drop in the beginning of the event on 11.17.2014, and straightforward installation of a planetary valley across the Moroccan coast on 11.24.2014, which has evolved into storm (Xandra) in which depression has reached the surprising value of 975 hPa on 11.28.2014.Human and material damage caused by this flood are impressive: people died, roads, bridges and crops have been destroyed, overwhelmed dams. It has been a catastrophe.This event and others like it (Mohammedia 2002, Tangier 2008, Gharb 2009-2010, Casablanca 2010), must be considered as references for the simulation of future situations, and integration into development plans on future.This communication aims to identify the processes and conditions that have generated these events causing floods, the "exceptional" characteristics of recorded rainfall, the spatial and temporal distribution of events. Those floods affect the whole country, especially low areas, foothills and the mouths of rivers. There are the most vulnerable locations mainly on the autumn which is the most exposed to torrential rainfall season !! ... Etc.

    The North-western coast of Morocco has approximately 160 km from Asila city while passing by the towns of Tangier, Fnideq, M'diq and Tetouan to Oued Laou and shelters wetlands (lake Smir.), beaches, cliffs and mountains. Investigations carried out in 2000-2001 in this zone show scattered beaches and wetlands (Smir lake, Maleh river) polluted by oil. These polluted beaches and coastal wetlands are generally close to Marina or fishing ports and to the residential areas. Cases of fish (Rays and other Chondrychtiens), tortoises (Caretta caretta) and dolphins dead have been noted in some of these beaches during spring and summer (2000-2001) most probably because of oil pollution. Increased dredging in beaches (Haouara, Martil...) involves the salinity of the ground water and the disturbance of the marine biodiversity. Some management (construction of Kabila marina and Smir dam) involved disturbance of hydrology (salinity increased) and biodiversity (migration of the Birds from Smir lake towards Smir dam) in Smir lake. This management, dredging, algae extraction and oil act on the coastal biodiversity and involve the deterioration of the natural environment. The beaches polluted by oil obstruct the tourism activity. Measurements of prevention (by prohibition to get rid of the motor oil and the washing of the boats on the open sea, construction of sewage stations and industrial water purification) are necessary for the conservation of biological diversity and the tourism development. The cleaning of the beaches polluted within the framework of the activities of the ONG or the local communities is also necessary. An integrated coastal zone management is necessary for the nature conservation and the sustainable development of the North Western of Morocco. Keywords: Oil pollution, Biodiversity, Coast, Morocco.

    A Water Footprint Assessment is carried out for Morocco, mapping the water footprint of different activities at river basin and monthly scale, distinguishing between surface- and groundwater. The paper aims to demonstrate the added value of detailed analysis of the human water footprint within a country and thorough assessment of the virtual water flows leaving and entering a country for formulating national water policy. Green, blue and grey water footprint estimates and virtual water flows are mainly derived from a previous grid-based (5×5 arc minute) global study for the period 1996–2005. These estimates are placed in the context of monthly natural runoff and waste assimilation capacity per river basin derived from Moroccan data sources. The study finds that: (i) evaporation from storage reservoirs is the second largest form of blue water consumption in Morocco, after irrigated crop production; (ii) Morocco’s water and land resources are mainly used to produce relatively low-value (in US$/m3 and US$/ha) crops such as cereals, olives and almonds; (iii) most of the virtual water export from Morocco relates to the export of products with a relatively low economic water productivity (in US$/m3); (iv) blue water scarcity on a monthly scale is severe in all river basins and pressure on groundwater resources by abstractions and nitrate pollution is considerable in most basins; (v) the estimated potential water savings by partial relocation of crops to basins where they consume less water and by reducing water footprints of crops down to benchmark levels are significant compared to demand reducing and supply increasing measures considered in Morocco’s national water strategy.

    The Moulouya river has the largest catchment in Morocco and drains an area characterized by active crustal deformation during the Late Cenozoic due to the N-S convergence between the African and Eurasian plates. As yet, its Pleistocene terrace sequence remains poorly documented. Our study focuses on the lowermost reach of the river in north-eastern Morocco, which drains the Zebra-Triffa sedimentary basin directly upstream of the estuary. New field observations, measurements and sedimentological data reveal contrasting fluvial environments on each side of a newly identified, W-E striking thrust zone disrupting the sedimentary basin. On the one hand, long-lasting fluvial aggradation, materialized by 37 m-thick stacked terraces, has occurred in the footwall of the thrust. On the other hand, the hanging wall is characterized by a well-preserved terrace staircase, with three Pleistocene terrace levels. Whilst the identification of this thrust zone question some previous interpretations about the local (hydro-)geology, it is consistent with the statement that most of the Plio-Quaternary deformation in the eastern Rif mountains has concentrated in this region of Morocco. Our new data and interpretations also agree with morphometric indicators showing that the whole Moulouya catchment is at desequilibrium state (i.e. several knickzones in its longitudinal profile), showing several knickzones in its longitudinal profile, is at disequilibrium state. We also suggest that the knickzone in the Beni Snassen gorge, located directly upstream of the Zebra-Triffa sedimentary basin, could (partly) result from a transient fluvial reaction to Late Cenozoic thrusting activity and correlated uplift in the hanging wall.

    A study of planktonic and benthic foraminifera from 17 marl samples of the upper Late Miocene to the Early Pliocene from the Eastern Rabat area (Morocco) was carried out. The benthic fauna is analyzed quantitatively and sorted by a cluster analysis. The resulting faunal assemblages, together with the Planktonic/Benthic-ratio and the species richness, are attached to three different environments: an Ammonia beccarii-assemblage of the inner shelf (inner neritic); a Hanzawaia boueanum-assemblage of the middle shelf (middle neritic); and a Planulina ariminensis-assemblage of the upper slope (upper bathyal). In their temporal succession they represent a transgression-regression sequence.

    Different glazed ceramics and glass artifacts, coming from the excavations of the Sijilmassa site and exhibited in CERA (center for Alaouite studies and research) in Rissani (Morocco), were analysed by portable X-ray fluorescence spectrometry. All glazed ceramics are lead glaze and their ceramic bodies are calcareous clay. Glass objects are different nature: lead-glass, lead-lime-alkaline and potassium-lime glass. Classical elements were used to colour glaze and glass: tin for white, cobalt ore for blue, copper for green, manganese and iron for black and iron for yellow.

    The analyses of wide-angle reflections of controlled source experiments and receiver functions calculated from teleseismic events provide consistent constraints of an over-thickened crust beneath the Rif Cordillera (North Morocco). Regarding active source data, we investigate now offline arrivals of Moho-reflected phases recorded in RIFSIS project to get new estimations of 3D crustal thickness variations beneath North Morocco. Additional constrains on the onshore-offshore transition are derived from onland recording of marine airgun shots from the coeval Gassis-Topomed profiles. A regional crustal thickness map is computed from all these results. In parallel, we use natural seismicity data collected throughout TopoIberia and PICASSO experiments, and from a new RIFSIS deployment, to obtain teleseismic receiver functions and explore the crustal thickness variations with a H-κ grid-search approach. The use of a larger dataset including new stations covering the complex areas beneath the Rif Cordillera allow us to improve the resolution of previous contributions, revealing abrupt crustal changes beneath the region. A gridded surface is built up by interpolating the Moho depths inferred for each seismic station, then compared with the map from controlled source experiments. A remarkably consistent image is observed in both maps, derived from completely independent data and methods. Both approaches document a large modest root, exceeding 50 km depth in the central part of the Rif, in contrast with the rather small topographic elevations. This large crustal thickness, consistent with the available Bouguer anomaly data, favor models proposing that the high velocity slab imaged by seismic tomography beneath the Alboran Sea is still attached to the lithosphere beneath the Rif, hence pulling down the lithosphere and thickening the crust. The thickened area corresponds to a quiet seismic zone located between the western Morocco arcuate seismic zone, the deep seismicity area

    A repertory of Roman military bronze equipment (1st- 3rd century AD) found at the archaeological site of Thamusida (Rabat, Morocco) was analysed by non-destructive X-ray fluorescence and time of flight neutron diffraction (ToF-ND). Most objects are made of leaded alloys, where copper is combined with tin and/or zinc and, in six cases, to arsenic as well. A mixed technology was employed, making a limited use of "pure" semi-finished materials if compared with the large utilization of recycled materials (brass and bronze).

    Pilot region of the GeRiSa project (Gestion des risques de l'environnement dans la région de Safi) is the Sahel of Abda (Morocco) located on the Atlantic coast of western Morocco between the lagoon of Oualidia and the Tensift river basin. It belongs to the Coastal Meseta and forms an erosional platform covered by accumulations of various Meso-cenozoic sediments. Firstly, the study area is characterized by a variety of geomorphological units (depressions, plateaus, cliffs, dunes, estuaries, etc.) and shows a considerable natural richness. Secondly, it illustrates its importance for the national economy by intensive social and economic activities. During the last century, this region has been affected by intensive changes from urban growth, tourism, industrial and commercial development, inducing a considerable vulnerability to natural hazards such as coastal erosion, landslides, flooding, Tsunamis and seismicity. In order to give solutions to these problems, the three-year GeRiSa project with the support of the bilateral Moroccan-German Programme of Scientific Research (PMARS) promoted by the Federal Ministry of Education and Research (BMBF) and the German Aerospace Center (DLR), will implement a knowledge pool and a risk management centre for natural hazards at the Polydisciplinary Faculty of the Cadi Ayyad University of Safi (Morocco). GeRiSa addresses fundamental scientific, environmental and anthropological problems of national importance and social relevance. The aim is a regional real-time geoinformation system with worldwide access via Internet and interdisciplinary dynamic content, enabling the communication between universities, local authorities and public organisation. In this sense, this multidisciplinary project focuses on a synthesis of various works, approaches and collaborations in-progress, previous completed projects and already existing data combining it with new research results. One of the main research targets within this project is the

    The origin of the Triassic-Jurassic (Tr-J) mass extinction is still a matter of debate: proponents of the idea that continental flood basalts of the Central Atlantic Magmatic Province (CAMP) are responsible for the crisis are opposed by those who favor an extraterrestrial origin linked to the impact of meteorite. Principal limitations reside in the difficulty to date and correlate CAMP lavas with the marine realm turnover. One argument widely used to suggest that CAMP lavas pre-dated the Tr-J boundary in Morocco is based on the presence of two brief magnetic reversals in the intermediate units of the Tiourjdal and Oued Lahr sections (Morocco) that were correlated to the E23r chron from the Newark basin and to the SA5n.2r/3r and SA5r chrons of the Saint Audrie Bay [Knight, K.B., Nomade, S., Renne, P.R., Marzoli, A., Betrand, H., Youbi, N., 2004. The Central Atlantic Magmatic Province at the Triassic-Jurassic boundary: paleomagnetic and 40Ar/ 30Ar evidence from Morocco for brief, episodic volcanism. Earth and Planetary Science Letters 228, 143-160]. However the primary origin for these negative (reverse) magnetic components is questionable since no field or reversal test was provided to constrain the primary character of the remanence as well as because the small number of samples. Here we have conducted a detailed paleomagnetic and magnetic mineralogy study of the interbedded limestones of the Tiourjdal section and of other CAMP lavas sections where the intermediate unit is complete, namely the Tizi El Hajaj, Jbel Imzar and Aït Ourir sections, to better constrain the origin and stratigraphic location of these negative magnetic components. We show that the interbedded limestones of the Tiourjdal section were entirely remagnetized by chemical processes via acid and oxidizing hydrothermal fluids generated by eruptions of CAMP lavas. In addition, magnetostratigraphic data of the Tizi El Hajaj, Jbel Imzar and Aït Ourir sections show that the entire intermediate unit

    The aim of this study was to determine potential relationships between anthropometric parameters and athletic performance with special consideration to repeated-sprint ability (RSA). Sixteen players of the senior male Qatar national soccer team performed a series of anthropometric and physical tests including countermovement jumps without (CMJ) and with free arms (CMJwA), straight-line 20 m sprint, RSA (6 × 35 m with 10 s recovery) and incremental field test. Significant (P < 0.05) relationships occurred between muscle-to-bone ratio and both CMJs height (r ranging from 0.56 to 0.69) as well as with all RSA-related variables (r < -0.53 for sprinting times and r = 0.54 for maximal sprinting speed) with the exception of the sprint decrement score (Sdec). The sum of six skinfolds and adipose mass index were largely correlated with Sdec (r = 0.68, P < 0.01 and r = 0.55, P < 0.05, respectively) but not with total time (TT, r = 0.44 and 0.33, P > 0.05, respectively) or any standard athletic tests. Multiple regression analyses indicated that muscular cross-sectional area for mid-thigh, adipose index, straight-line 20 m time, maximal sprinting speed and CMJwA are the strongest predictors of Sdec (r(2) = 0.89) and TT (r(2) = 0.95) during our RSA test. In the Qatar national soccer team, players' power-related qualities and RSA are associated with a high muscular profile and a low adiposity. This supports the relevance of explosive power for the soccer players and the larger importance of neuromuscular qualities determining the RSA.

    Purpose: The aim of this study was to evaluate radiation doses to pediatric patients undergoing standard radiographic examinations using Direct Digital Radiography (DDR) in Paediatric emergency center of Hamad General Hospital (HGH) in state of Qatar and compared with regional and international Dose Reference Levels (DRLs). Methods: Entrance Skin Dose (ESD) was measured for 2739 patients for two common X-ray examinations namely: Chest AP/PA, Abdomen. Exposure factors such as kV, mAs and Focal to Skin Distance (FSD) were recorded for each patient. Tube Output was measured for a range of selected kV values. ESD for each individual patient was calculated using the tube output and the technical exposure factors for each examination. The ESD values were compared with the some international Dose Reference Levels (DRL) for all types of examinations. Results: The most performed procedure during the time of this study was chest PA/PA (85%). The mean ESD values obtained from AP chest, PA chest and AP abdomen ranged 91–120, 80–84 and 209 – 659 µGy per radiograph for different age’s groups respectively. Two protocols have been used for chest AP and PA using different radiological parameters, and the different of ESD values for chest PA and were 41% for 1 years old child, 57% for 5 years old for chest AP. Conclusion: The mean ESD were compared with those found in literature and were found to be comparable. The radiation dose can be reduced more for Chest AP and PA examination by optimization of each investigation and hence more studies are required for this task. The results presented will serve as a baseline data needed for deriving local reference doses for pediatric X-ray examinations in this local department and hence it can be applied in the whole Qatar.

    Phlebotomine sand flies (Diptera: Psychodidae) were collected continuously, using sticky traps, during 1 year from October 2002 to September 2003, in an urban area of Marrakech city (Morocco). A total of 3277 specimens were collected belonging to five species. Phlebotomus (Phlebotomus) papatasi (54.6%) is the predominant species followed by Sergentomyia (Sergentomyia) minuta (20%), S. (S.) fallax (11.3%), P. (Paraphlebotomus) sergenti (10.3%) and P. (Larroussius) longicuspis (3.8%). Data analyses showed a mono-modal annual pattern for P. sergenti and a bi-modal one for the other species. P. papatasi, the proven vector of Leishmania major in Morocco, was active throughout the year. This species did not diapause in this region. P. papatasi population peaked in June and November, which relating to the periods of risk in this area. Its preferred temperature ranged between 32 and 36 degrees C but no significant correlation was found between its density and the temperature. Considering the high density and long activity period of P. papatasi, the area of Marrakech should be regarded as a potential focus for L. major. This suggests the need for a continuously surveillance to prevent risk of zoonotic cutaneous leishmaniasis.

    The isolation of patulin-producing Penicillia in apples collected in different markets in four localities in Morocco is reported. Fungi were identified by β-tubulin sequencing and further characterized using a specific PCR-based method targeting the isoepoxydon dehydrogenase (IDH) gene to discriminate between patulin-producing and non-producing strains. Production of patulin was also evaluated using standard cultural and biochemical methods. Results showed that 79.5% of contaminant fungi belonged to the genus Penicillium and that Penicillium expansum was the most isolated species (83.9%) followed by Penicillium chrysogenum (~9.7%) and Penicillium crustosum (~6.4%). Molecular analysis revealed that 64.5% of the Penicillium species produced the expected IDH-amplicon denoting patulin production in these strains. However, patulin production was not chemically confirmed in all P. expansum strains. The isolation of IDH(-)/patulin(+) strains poses the hypothesis that gentisylaldehyde is not a direct patulin precursor, supporting previous observations that highlighted the importance of the gentisyl alcohol in the production of this mycotoxin. Total agreement between IDH-gene detection and cultural/chemical methods employed was observed in 58% of P. expansum strains and for 100% of the other species isolated. Overall the data reported here showed a substantial genetic variability within P. expansum population from Morocco.

    Juniperus thurifera L. is an important tree endemic to the western Mediterranean basin that it is able to grow in semi-arid climates. It nowadays exhibits a disjunct distribution pattern, occurring in North Africa, Spain, France and the Italian Alps. The Strait of Gibraltar has acted as an efficient barrier against gene flow between African and European populations, which are considered different subspecies by some authors. We aimed at describing the intraspecific genetic diversity of J. thurifera in populations from the Iberian Peninsula and Morocco and the phylogeographical relationships among these populations. The ploidy level of J. thurifera was examined and eleven nuclear microsatellites (nSSRs) developed for J. thurifera were assessed for genotyping this species. Six nSSRs were polymorphic and subsequently used to assess the genetic diversity and structure of the studied populations. Genotyping of the tetraploid J. thurifera using nuclear microsatellites supports the separation of Moroccan and Spanish populations into two genetically differentiated groups that correspond to the proposed subspecies africana and thurifera. High values of within population genetic diversity were found, that accounted for 90% of the total genetic variance, while population structure was weak. The estimators of genetic diversity were higher in populations of Spain than in populations of Morocco pointing for a possible loss of genetic diversity during the spread of this species to Africa from Europe.

    Geomorphological heritage is a widely used term in European and North-American countries, but is still scarcely mentioned in Africa. Nevertheless, the attractiveness of the African countries is often intimately connected to its breathtaking and endless geological landscapes. Morocco is one of those countries that has the widest diversity in landscapes and landforms, ranging from the Mediterranean and Atlantic coasts over the Rif, Middle Atlas, High Atlas and Anti-Atlas mountain chains to the great rocky and sandy deserts in the South. A wide variety of geological units hosting different types of important economic mineral deposits cover a temporal range from Late Precambrian to Quaternary. A detailed geomorphological study has been carried out in the region of Ifrane and Azrou (Middle Atlas, Central Morocco) using a combination of high resolution satellite data and direct field observations integrated by geological maps and scientific literature. In order to describe and evaluate the geomorphological heritage of this area, 40 geomorphosites have been selected comprising springs, karst landforms (polje, dolines, caves, sinkholes, stone forests, cryptokarstic dolines), carbonate depositional landforms (travertines and waterfalls), fluvial landforms (meanders, canyons, palaeo-valleys, etc.), structural landforms (triangular facets, hogbacks, cuestas, residual outcrops, etc.) and volcanic landforms (volcanoes, caldeira, pyroclastic cones, lava tube). The results of this research have been summarised in a thematic map, representing the geomorphosites related to various landscape units.

    A retrospective study was conducted of burn patients admitted to the military hospital in Rabat, Morocco, in the 6-yr period from 2004 to 2009. This is the first multivariate study to be performed in Morocco. The epidemiological data from the 291 patients hospitalized were collected and studied. The type of burn was indicated in 284 of the patients: 94% of the injuries were thermal burns, 4% were electrical burns, and 1.5% chemical burns. In 261 cases the exact aetiology was noted: 56% of accidents were caused by flames, 38% by hot liquids, 4% by electric current, and 2% by chemicals. The distribution of the Moroccan population is as follows: 0-4 yr, 7%; 5-l4 yr, 8%; 15-19 yr, 8%; 20-59 yr, 70%; over 60 yr, 7%. The male/female sex ratio was 1.63. The mean duration of hospitalization stay was 42 ± 62 days. The mean body surface area burned was 21 ± 18%. Total mortality was 5%; 57% of deaths were due to septic shock. Our results were similar to data from other studies in the literature, with certain characteristics in our series, especially the age bracket most affected, the body surface area burned, and the mechanisms of injury.

    Fifty eight (58) samples of cereals for human consumption (20 corn flour, 17 wheat flour) and poultry feeds (n=21) purchased from popular markets of Rabat in Morocco were analyzed for aflatoxins (AF) by HPLC with immunoaffinity column (IAC) clean-up and fluorimetric detection. The incidence of AF in corn, wheat flour and poultry feeds was about 80, 17.6 and 66.6% respectively. High contamination levels were found in corn and poultry feeds samples. Levels of contamination of analyzed samples with AFB1 ranged from 0.23 to 11.2, 0.03 to 0.15 and 0.05 to 5.38 ng/g for corn, wheat and poultry feeds respectively. Results showed also that the contamination of 10% of samples of corn was higher than the limit set by EU regulations for AFB1 and total AF. This is the first report on the determination of AF in corn, wheat and poultry feeds from Morocco by HPLC and IAC.

    Previous studies have shown that Argan fruits contain a large variety of polyphenolic compounds. Recently, another class of polyphenolic compounds, namely amino phenols have been detected and identified in immature Argan fruits. The objective of this study, was to establish whether or not, these novel compounds are also present in mature Argan fruits. To this end, a comparison was made between mature fruits from two regions of Morocco. Nineteen major compounds were identified and quantitated, including amino phenols, flavonoids, and phenolic acids by chromatographic methods in mature Argan fruits from the two regions of Morocco (Essaouira and Agadir). The phenolic acids were identified as gallic acid and 3,4-dihydroxybenzoic acid; the amino phenols as Arganimide A, and argaminolics A-C, and the flavonoids as rutin pentoside, quercetin-3-O-arabinoside, quercetin glycogallate, quercetin-3-O-rhamnogalactoside, rutin, quercetin-3-O-galactoside (hyperoside), quercetin-3-O-glucoside (quercitrin), quercetin-3-O-arabinoside, quercetin glycohydroxybenzoate, quercetin glycosinapate, quercetin glycoferulate, quercetin glycocoumarate and quercetin. n=145.

    Cutaneous leishmaniasis (CL) is a major public health problem in Morocco. Three distinct parasites are involved; Leishmania tropica, Leishmania major and Leishmania infantum. The objective of this study is to investigate the epidemiological and the clinical features of endemic foci of CL in Sidi Kacem and Ouazzane provinces in the north of Morocco including molecular identification of parasites. We studied the evolution and the distribution of 1,656 CL cases coming from 39 sectors in these provinces between 1997 and 2012. The causative agents of CL in these areas were identified by using the ITS1-PCR-RFLP method. A tendency of seasonality in incidence was observed, showing a peak in April. Most infected patients were from Ouazzane province. The patients' ages ranged from 6 months to 85 years; 54% of them were females. The highest rate lesions were found in the age group of 9 years or less and most lesions were localized in the face (79.6%). The movement of populations from neighboring endemic areas and establishment of habitation in areas where housing conditions are unfavorable favored the emergence of the disease.

  8. Highlights of NASA/DOE photovoltaic market assessment visit to Morocco

    1981-01-01

    A broad range of agricultural, rural development, and other power applications in various regions of Morocco were examined to determine the potential market for photovoltaic products in Moroccan development. The primary focus of the study was the agriculture sector which accounts for approximately 17% of the country's GNP. The country has a clear need for reliable remote power systems, but does not have the financial resources to invest in the relatively high capital cost PV equipment. A modest potential for PV use was identified in nonagricultural rural services, such as refrigerators for rural clinics and rural radio-telephones. The main potential for PV in Morocco in the next five years lies mainly in the telecommunications sector. Applications include rural TV sets, TV repeater stations, microwave relay stations, and railroad, marine, and airline signalling. Market size estimates were derived from development and expansion plans. At an average customer cost for complete installed systems from $18/Wp to $30/Wp the total potential market value is estimated in the range of $6.6 to $11 million over the 1981-1986 period.

    Results of a month-long study in Morocco aimed at assessing the market potential for stand-alone photovoltaic systems in agriculture and rural service applications are presented. The following applications, requiring less than 15 kW of power, are described: irrigation, cattle watering, refrigeration, crop processing, potable water and educational TV. Telecommunications and transportation signalling applications, descriptions of power and energy use profiles, assessments of business environment, government and private sector attitudes towards photovoltaics, and financing were also considered. The Moroccan market presents both advantages and disadvantages for American PV manufacturers. The principle advantages of the Moroccan market are: a limited grid, interest in and present use of PV in communications applications, attractive investment incentives, and a stated policy favoring American investment. Disadvantages include: lack of government incentives for PV use, general unfamiliarity with PV technology, high first cost of PV, a well-established market network for diesel generators, and difficulty with financing. The market for PV in Morocco (1981-1986), will be relatively small, about 340 kwp. The market for PV is likely to be more favorable in telecommunications, transport signalling and some rural services. The primary market appears to be in the public (i.e., government) rather than private sector, due to financial constraints and the high price of PV relative to conventional power sector.

    Clays are a natural resource used for millennia. Currently applications such as industrial minerals are diversified. In this context, our goal is to estimate the potential of the many clay deposits in northern of Morocco. The choice of this region is justified by the particular abundance of clay deposits used to manufacture building materials (brick, ceramic and refractories) and pottery. This study focuses on the mineralogical, chemical and geotechnical characterization tests carried out on Tangier-Tetouan and Meknes clays from northern of Morocco. The suitability of raw clay material from those regions in order to produce ceramic and brick has not been tested yet. The results revealed that the studied samples are diversified, kaolinite and illite (Tetouan clay) and kaolinite and illite and smectite and vermiculite (Tangier and Meknes clay) based materials. There were no major differences in grain-size distribution, whereas Meknes clay was more plastic than Tetouan-Tangier clay. The cation exchange capacity show that Meknes and Tangier clay were more important than Tetouan clay. Specific surface area and thermal analaysis complete this caracterization. It was found that almost all technological properties of the Meknes clay deposit are led to the manufacture of ceramic floor tile, and Tetouan-Tangier clay provide opportunities to making brick and ceramic floor. The Tetouan-Tangier and Meknes clay are a potential ceramic raw material for growing Morrocan ceramic tile and brick industries.

    Juniperus thurifera L. is an important tree endemic to the western Mediterranean basin that it is able to grow in semi-arid climates. It nowadays exhibits a disjunct distribution pattern, occurring in North Africa, Spain, France and the Italian Alps. The Strait of Gibraltar has acted as an efficient barrier against gene flow between African and European populations, which are considered different subspecies by some authors. We aimed at describing the intraspecific genetic diversity of J. thurifera in populations from the Iberian Peninsula and Morocco and the phylogeographical relationships among these populations. The ploidy level of J. thurifera was examined and eleven nuclear microsatellites (nSSRs) developed for J. thurifera were assessed for genotyping this species. Six nSSRs were polymorphic and subsequently used to assess the genetic diversity and structure of the studied populations. Genotyping of the tetraploid J. thurifera using nuclear microsatellites supports the separation of Moroccan and Spanish populations into two genetically differentiated groups that correspond to the proposed subspecies africana and thurifera. High values of within population genetic diversity were found, that accounted for 90% of the total genetic variance, while population structure was weak. The estimators of genetic diversity were higher in populations of Spain than in populations of Morocco pointing for a possible loss of genetic diversity during the spread of this species to Africa from Europe.

    The purpose of this paper is to provide a summary of Morocco's climate extreme trends during the last four decades. Indices were computed based on a daily temperature and precipitation using a consistent approach recommended by the ETCCDI. Trends in these indices were calculated at 20 stations from 1970 to 2012. Twelve indices were considered to detect trends in temperature. A large number of stations have significant trends and confirm an increase in temperature, showing increased warming during spring and summer seasons. The results also show a decrease in the number of cold days and nights and an increase in the number of warm days and nights. Increasing trends have also been found in the absolute warmest and coldest temperatures of the year. A clear increase is detected for warm nights and diurnal temperature range. Eight indices for precipitation were also analyzed, but the trends for these precipitation indices are much less significant than for temperature indices and show more mixed spatial patterns of change. Heavy precipitation events do not exhibit significant trends except at a few locations, in the north and central parts of Morocco, with a general tendency towards drier conditions. The correlation between these climate indices and the large-scale atmospheric circulations indices such as the NAO, MO, and WEMO were also analyzed. Results show a stronger relationship with these climatic indices for the precipitation indices compared to the temperature indices. The correlations are more significant in the Atlantic regions, but they remain moderate at the whole country scale.

    We investigate the respective roles of crustal tectonic shortening and asthenospheric processes on the topography of the High Atlas and surrounding areas (Morocco). The lithospheric structure is modeled with a direct trial-and-error algorithm taking into account gravity (Bouguer and free air), geoid, heat flow, and topography. Three parallel cross sections, crossing the High Atlas and Anti-Atlas ranges, show that the lithosphere is thinned to 60 km below these mountain ranges. An analysis of the effect of the lithospheric thinning allows us to conclude that the whole topography of the Anti-Atlas, which belongs to the Sahara domain, is due to asthenospheric processes. In the High Atlas the lithospheric thinning explains a third of the relief of the western High Atlas, 500 m for a mean altitude of 1500 m, and half of the relief of the central High Atlas, 1000 m for a mean altitude of 2000 m. At the scale of Morocco the domain affected by lithospheric thinning forms an elongated NE-SW strip crossing not only the main structural zones but also the Atlantic margin to the south and the Africa-Eurasia plate boundary to the north. This major lithospheric thinning is associated with Miocene to recent alkaline volcanism and seismicity. We propose that this thermal anomaly is related to a shallow mantle plume, emplaced during middle to late Miocene time, during a period of relative tectonic quiescence.

    Astronomy education in Morocco, like in many developing countries, is not well developed and lacks the very basics in terms of resources, facilities and research. In 2004, the International Astronomical Union (IAU) signed an agreement of collaboration with Al Akhawayn University in Ifrane to support the continued, long-term development of astronomy and astrophysics in Morocco. This is within the IAU program "Teaching for Astronomy Development" (TAD). The initial focus of the program concentrated exclusively on the University's Bachelor of Science degree program. Within this program, and during two years, we were successful in providing adequate astronomy training to our physics faculty and few of our engineering students. We also offered our students and community general astronomy background through courses, invited talks and extra curricular activities. The project is now evolving towards a wider scope and seeks promoting astronomy education at the high school level. It is based on modules from the Hands on Universe (HOU) interactive astronomy program. Moroccan students will engage in doing observational astronomy from their PCs. They will have access to a world wide network of telescopes and will interact with their peers abroad. Through implementing astronomy education at this lower age, we foresee an increasing interest among our youth not only in astronomy but also in physics, mathematics, and technology. The limited astronomy resources, the lack of teachers experience in the field and the language barrier are amongst the difficulties that we'll be facing in achieving the objectives of this new program.

    Digital data from a telemetered, short-period seismic network in Morocco provide a new perspective for understanding the cause of severe shaking and macroseismic reports in Morocco produced by large offshore earthquakes located along the Azores-Gibraltar seismic zone. Even though the earthquake epicenters are 500-1000 km away from the Moroccan coast, historical records show that such events are capable of producing considerable damage in inland areas. We analyze 15 earthquakes that occurred in this region. The records show multiple S phases with varying frequencies and amplitudes. The S phase with the largest amplitude, usually misinterpreted as Sn, has a phase velocity of 4.2-4.4 km/s. We show that these S arrivals can best be explained as Sn to Sg converted phases. Calculated locations of the conversion points for these phases exhibit two distinct zones almost parallel to the Atlantic coastline: one is located along the passive continental margin and the other is located about 100 km inland from the coastline. We interpret these two zones to be regions where a sudden change in crustal thickness occurs. Such zones act to focus and magnify the amplitudes of seismic phases.

    Cutaneous leishmaniases (CL) are endemic in Morocco. They are common in the human population in different localities such as Aichoun in Sefrou province, Morocco. This study was carried out in Aichoun locality from April to October 2012 in order to study the spatiotemporal trends of the main Leishmania phlebotomine vectors in this focus. Overall, 1171 sand flies, belonging to four species, were collected by sticky traps. Phlebotomus sergenti was the predominant species (78.4%) followed by Ph. perniciosus (10.5%), Ph. papatasi (7.94%), and Ph. longicuspis (3.16%). Sandflies were active during 6 months (May–October). Ph. sergenti, Ph. perniciosus, and Ph. papatasi displayed a bimodal distribution with a first peak in July and a second peak in September, while Ph. longicuspis showed a monophasic trend with a peak in August. The high abundance and the lengthy period of activity of Ph. sergenti and Ph. perniciosus, vectors of L. tropica and L. infantum, respectively, are a cause for concern as they indicate the high potential risk of Leishmania transmission in the studied areas.

    The contamination of meat and meat products with Shiga toxin-producing O157:H7 and non-O157 Escherichia coli (STEC), obtained from markets in Casablanca, Morocco, was investigated. A total of 460 meat and meat products were sampled between March 2004 and July 2006 analysed and 176 strains of E. coli were isolated from these samples. The presence of the stx1, stx2, eae and ehxA genes, recognized as major virulence factors of STEC, was tested in E. coli isolates by polymerase chain reaction (PCR). STEC was detected in 4 (0.9%) samples. The result of serotyping by molecular method showed that two of these STEC isolates corresponded to the serotype O157:H7. The others Shiga toxin-producing E. coli non-O157 corresponded to O6:H21 and O76:H19. The presence of O157:H7 and non-O157 STEC in meat and meat products marketed in Casablanca, Morocco, emphasizes the importance of implementing the Hazard Analysis and Critical Control Point (HACCP) system, as well as the need for implementing, evaluating, and validating antimicrobial interventions to reduce the presence of potential pathogenic microorganisms.

    Abstract The results, of a conducted study carried out to analyze variations in ambient seismic noise levels at sites of the installed broadband stations in Morocco, North Africa, are obtained. The permanent and the temporary seismic stations installed in Morocco of the Scientific Institute ( IS, Rabat, Morocco), institute de Ciencias de la Tierra Jaume almera (ICTJA, Barcelona, Spain) and Institut für Geophysik (Munster, Germany) were used in this study. In this work, we used 23 broadband seismic stations installed in different structural domains covering all Morocco from south to north. The main purposes of the current study are: 1) to present a catalog of seismic background noise spectra for Morocco obtained from recently installed broadband stations, 2) to assess the effects of experimental temporary seismic vault construction, 3) to determine the time needed for noise at sites to stabilize, 4) to establish characteristics and origin of seismic noise at those sites. We calculated power spectral densities of background noise for each component of each broadband seismometer deployed in the different investigated sites and then compared them with the high-noise model and low-noise Model of Peterson (1993). All segments from day and night local time windows were included in the calculation without parsing out earthquakes. The obtained results of the current study could be used forthcoming to evaluate permanent station quality. Moreover, this study could be considered as a first step to develop new seismic noise models in North Africa not included in Peterson (1993).

    2013-01-01

    Background In Morocco, the social and legal framework surrounding sexual and reproductive health has transformed greatly in the past decade, especially with the introduction of the new Family Law or Moudawana. Yet, despite raising the minimum age of marriage for girls and stipulating equal rights in the family, child and forced marriage is widespread. The objective of this research study was to explore perspectives of a broad range of professionals on factors that contribute to the occurrence of child and forced marriage in Morocco. Methods A qualitative approach was used to generate both primary and secondary data for the analysis. Primary data consist of individual semi-structured interviews that were conducted with 22 professionals from various sectors: health, legal, education, NGO’s and government. Sources of secondary data include academic papers, government and NGO reports, various legal documents and media reports. Data were analyzed using thematic qualitative analysis. Results Four major themes arose from the data, indicating that the following elements contribute to child and forced marriage: (1) the legal and social divergence in conceptualizing forced and child marriage; (2) the impact of legislation; (3) the role of education; and (4) the economic factor. Emphasis was especially placed on the new Family Code or Moudawana as having the greatest influence on advancement of women's rights in the sphere of marriage. However, participants pointed out that embedded patriarchal attitudes and behaviours limit its effectiveness. Conclusion The study provided a comprehensive understanding of the factors that compound the problem of child and forced marriage in Morocco. From the viewpoint of professionals, who are closely involved in tackling the issue, policy measures and the law have the greatest potential to bring child and forced marriage to a halt. However, the implementation of new legal tools is facing barriers and resistance. Additionally, the legal and

    Among African countries, Morocco is probably one of the most exposed to tsunami hazard. Indeed, Morocco is integrated in the particular geodynamic context of the northern African margin characterized by the existence of the Azores-Gibraltar fault separating two active tectonic plates: the African and the Eurasian plates. This area generated and still generates many large earthquakes exceeding a magnitude of 6. The Moroccan Atlantic coasts are thus exposed to tsunamigenic earthquakes occurring offshore. Tsunamis generated in this area are not frequent but can be really disastrous and could have a huge impact. In the framework of the SCHEMA project, a 3 year European project, we studied the consequences on the Moroccan coastal area of two potential tsunami scenarios, applying the generic methodology developed during the project for building tsunami vulnerability and impact maps. The study focuses on the "Rabat Zaïr" region. Centred on the Bouregreg Valley, this study area encompasses three main coastal and densely populated towns of Morocco: Rabat (capital), Salé and Temara. Using a combination of numerical modelling, field surveys, earth observation and GIS data, the risk has been evaluated for this highly vulnerable area (flat topography, small beaches with many tourists in summer, presence of several bridges on the Bouregreg river separating Rabat and Salé, presence of a dam upstream the 2 cities, and development of a new residential and touristic complex on the coastline and in the vicinity of the estuary). Two scenarios of tsunami have been studied to estimate the hazard on the coastal zone of Rabat: a worst case scenario based on the historical Lisbon earthquake of 1755 as well as a moderate scenario based on the historical Portugal earthquake of 1969. For each scenario, numerical models allowed to produce inundation maps consisting of inundation limits as well as maximum water heights.

    In Morocco, Culex pipiens plays a role in the high annoyance experienced by most urban cities, suburban and rural areas, especially since it was strongly suspected as the most likely vector in the transmission of West Nile virus epidemics that have hit Morocco in 1996. Chemical insecticides are generally the way in which they use the programs against harmful mosquitoes and disease vectors. However, the repeated and excessive use of these products regularly led to the emergence of the phenomenon of insect resistance. At the center of Morocco, information on the susceptibility or resistance to insecticides in mosquitoes (larvae and adults) vectors of diseases or pests, are almost nonexistent. This article reports the results of studies conducted between 2007 and 2010 with sensitivity tests WHO on larvae local populations of Culex pipiens collected in three lodging in the city of Fez, towards the insecticide mostly used by hygienic services: temephos. Five concentrations of insecticide (0.0025 mg/l, 0.005 mg/l, 0.0125 mg/l, 0.025 mg/l, 0.0625 mg/l) in addition to control, were used to determine the LC50 and LC 90 of Culex pipiens species towards temephos. Sensitivity tests were carried out at the entomology unit and monitoring of insect sensitivity towards insecticides installed at the Regional Diagnostic Laboratory Epidemiological and Environmental Hygiene (LRDEHM), Fez, under the Regional Directorate of Health in Fes Boulemane Region. The LC50 and LC90, concentrations corresponding to 50 and 90% mortality were determined graphically, by the linear relationship between the decimal logarithm of insecticide concentrations (x-axis) and the percentage of mortality transformed into probit values (ordinate) on logarithmic gausso paper. Resistance rates were determined on the basis of the sensitivity of a reference strain (S-Lab). The bioassay results affirmed the presence of resistance in larvae Culex pipiens towards temephos and that this species has also equally

    The Moulouya river has the largest catchment in Morocco and drains an area which is characterized by active crustal deformation during the Late Cenozoic due to the convergence between the African and Eurasian plates. As yet, its Pleistocene terrace sequence remains poorly documented. Our study focuses on the lowermost reach of the river in NE Morocco, which drains the Triffa sedimentary basin directly upstream of the estuary. New field observations, measurements and sedimentological data reveal contrasted fluvial environments on either side of a newly identified thrust zone, which disrupts the whole sedimentary basin and is associated with N-S compressive shortening in this region (Barcos et al., 2014). Long-lasting fluvial aggradation, materialized by ≥37 m-thick stacked fill terraces, and the development of a well-preserved terrace staircase, with (at least) three Pleistocene terrace levels, occur in the footwall and the hanging wall of the thrust, respectively. Same as for the Pleistocene terrace sediments of the middle Moulouya, a recurrent sedimentary pattern, characterized by fining-upward sequences was observed in the studied terrace profiles. Assessing the rates of crustal deformation along this main thrust zone requires age estimations for these Pleistocene terrace deposits of the lower Moulouya on each side of the thrust. Samples for luminescence (OSL/IRSL), electron spin resonance (ESR, on quartz) and cosmogenic nuclide dating (26Al/10Be, burial dating) were collected in terrace deposits located both in the foot- and hanging walls. Sample preparation and analysis as well as age determination are in progress. The preliminary data mentioned above, soon to be completed by chronological data, agree well with morphometric indicators stating that the whole Moulouya catchment is at disequilibrium state (Barcos et al., 2014). This is confirmed by several knickpoints in its longitudinal profile. Late Cenozoic uplift associated with crustal shortening, which

    Context. Our understanding of the formation and evolution of planetary systems is still fragmentary because most of the current data provide limited information about the orbital structure and dynamics of these systems. The knowledge of the orbital properties for a variety of systems and at different ages yields information on planet migration and on star-planet tidal interaction mechanisms. Aims: In this context, a long-term, multi-purpose, observational programme has started with HARPS-N at TNG and aims to characterise the global architectural properties of exoplanetary systems. The goal of this first paper is to fully characterise the orbital properties of the transiting system Qatar-1 as well as the physical properties of the star and the planet. Methods: We exploit HARPS-N high-precision radial velocity measurements obtained during a transit to measure the Rossiter-McLaughlin effect in the Qatar-1 system, and out-of-transit measurements to redetermine the spectroscopic orbit. New photometric-transit light-curves were analysed and a spectroscopic characterisation of the host star atmospheric parameters was performed based on various methods (line equivalent width ratios, spectral synthesis, spectral energy distribution). Results: We achieved a significant improvement in the accuracy of the orbital parameters and derived the spin-orbit alignment of the system; this information, combined with the spectroscopic determination of the host star properties (rotation, Teff, log g, metallicity), allows us to derive the fundamental physical parameters for star and planet (masses and radii). The orbital solution for the Qatar-1 system is consistent with a circular orbit and the system presents a sky-projected obliquity of λ = - 8.4 ± 7.1 deg. The planet, with a mass of 1.33 ± 0.05 MJ, is found to be significantly more massive than previously reported. The host star is confirmed to be metal-rich ([Fe/H] = 0.20 ± 0.10) and slowly rotating (vsinI = 1.7 ± 0.3 km s-1

    The nocturnal activity of phlebotomine sandflies (Diptera: Psychodidae) was studied "at an epidemic focus" on human cutaneous leishmaniasis due to Leishmania tropica Wright in Chichaoua province, in Morocco. Sandflies were collected using light and sticky-paper traps changed at 2-h intervals, inside and around houses, in August and October 2004. Overall, 633 sandflies, belonging to six species of Phlebotomus and three of Sergentomyia, were collected. Sandfly activity was nocturnal and higher at twilight. Several activity patterns were observed according to the species. Phlebotomus (Paraphlebotomus) sergenti Parrot, 1917, the suspected vector of L. tropica in this focus, was caught during each collection performed from 1900 to 0500 hours, the numbers of species caught peaked at 1900-2100 hours. There were seasonal variations of the nocturnal activity, which could be related to the variations in temperature and relative humidity.

    A mosaic constructed from three ERTS MSS band 5 images enlarged to 1:500,000 compares favorably with a similar scale geologic map of southern Morocco, and a near-similar scale Gemini 5 photo pair. A comparative plot of lineations and generalized geology on the three formats show that a significantly greater number of probable fractures are visible on the ERTS imagery than on the Gemini photography, and that both orbital formats show several times more lineaments than were previously mapped. A plot of mineral occurrences on the structural overlays indicates that definite structure-mineralization relationships exist; this finding is used to define underdeveloped areas which are prospective for mineralization. More detailed mapping is possible using MSS imagery than on Gemini 5 photographs, and in addition, the ERTS format is not restricted to limited coverage.

    The allele frequency distribution of 15 short tandem repeats (STR) loci contained in the AmpFlSTR Identifiler PCR Amplification Kit (Applied Biosystems), was determined in two Berber populations from Asni and Bouhria, in Central and Eastern Morocco, respectively. A total of 209 individuals were typed. No deviations from the Hardy-Weinberg equilibrium were observed for Asni at the 15 STRs loci whereas for the Bouhria samples, two loci (D5S818 and TH01) showed significant departures from Hardy-Weinberg expectations (after Bonferroni's correction). All loci are highly polymorphic and population differentiation tests showed that the Moroccan samples from Asni and Bouhria have significant differences in 4 out of 15 loci (D21S11, D7S820, D16S539 and TPOX). The aim of the study was to obtain accurate allele frequencies relevant for forensic applications. Comparative analyses between our population data and other population samples gathered from the literature are also presented.

    Wollastonite outcrops at the Palaeozoic terrains of the central haut-atlas (Morocco), as irregular bodies together with garnets, pyroxenes and vesuvianite. Its formation is genetically linked to the intrusion of the Azegour post-Hercynian granite, which cut various rocks (carbonates, schistosed sandstones and volcanic complex) and induced a high-temperature contact metamorphism. Emanations from the intrusive fluid flows, principally consisting of silica and iron, reacted with calcareous rocks for forming calc- and iron-silicates assemblages (wollastonite, garnet and pyroxene). Investigations realized by X-ray diffraction, optical and scanning electron microscopes, and electron microprobe showed that wollastonite is a pure and good crystallized mineral with the chemical formula [Ca 0.96Mn 0.02Fe 0.01P 0.01]SiO 3, and the aspect- ratio (length to diameter) of the fibers is very high (>20:1).

    Firing technological properties ( linear shrinkage, apparent density, open porosity and bending strength) of a raw clay from Ourzazat (Morocco) were measured for 850 ≤ T ≤ 1125° C and correlated to the microstructure changes. The slight increase of porosity and the feeble reduction of density observed for T < 1000 ° C, are linked to the escape of CO{2}, resulting from the decomposition of dolomite. The almost constancy of linear shrinkage is related to the opposite effects due to the neocristallization of pyroxenes and olivine, and the onset of the sintering process. The latter magnesian phases arise from the decomposition of fibrous minerals and dolomite. For higher temperatures, the drastic increases of density, linear shrinkage and bending strength, which are intended by a sharp reduction of porosity, is interpreted in terms of a quantitative development of melt. On the other hand, it is observed that the colour of shards changes likely because of the concomitant disappearance of hematite and formation of pyroxenes.

    Despite the severity of land degradation in Morocco, only limited data are available on the actual magnitude of soil erosion rates. Most of the previous research used conventional measurements. Since the mid 1990's only a few studies reported the use of the 137-Cs approach and, excess lead-210 (210-Pbex) as soil tracer in Morocco. The site under investigation is a one hectare agricultural field dominated by cereals under conventional tillage (plough depth ~ 16 cm) and semiarid climate located in Marchouch 68 km south east from Rabat (Morocco). In this field, 50 soil core samples were collected along 5 parallel transects. The initial 137-Cs and 210-Pb fallout were assessed through 12 core samples collected in an undisturbed pasture located 3 km from the field studied. After γ-spectrometry analysis, the areal activities of 137-Cs and 210-Pbex were converted into soil redistribution rates using the convertion model Mass Balance Model II (MBM II). Soil redistribution rates obtained from both isotopes were analyzed using geostatistic approach and a classical interpolation concept (Inverse Distance Weighting (IDW)). Maps of soil redistribution were established and a sediment budget for the whole field was calculated. For the reference site, the vertical distribution associated with both radionuclides was similar and concentrated in the top 10 cm with a clear exponential decrease with depth. The reference inventories values were estimated at 3305 Bq m-2 (n = 12; CV of 30%) and 1445 Bq m-2 (n = 12; CV of 18%) for 210-Pbex and 137-Cs, respectively. For the cultivated site, experimental variograms of soil redistribution rate calculated from the data provided by the 137-Cs and 210-Pbex results were fitted. Following the optimization of variographic parameters and the cross-validation analysis, the geostatistical study of the data set reported a very weak autocorrelation. So, a simple spatialisation of the data set using IDW2 was used to spatialise the soil redistribution

    How might the ethnographer conduct research on health and suffering among populations who would rather remain hidden? Drawing on my research with female sex workers in southern Morocco, I suggest and demonstrate an approach that allows interlocutors' discretionary practices to guide ethnographic inquiry. I show how boundary work--as a politics of visibility founded on practices of discretion, concealment, and distancing--emerged as central to my interlocutors' livelihood strategies and their efforts to enact moral personhood, integrate themselves into networks of solidarity, and articulate social critiques. A methodological focus on discourses and practices of boundary drawing, I argue, was essential for conceptualizing and representing the suffering of the women with whom I worked. Using boundary work as a guide, the ethnographer does not give voice to suffering, but learns how suffering is already voiced as part of attempts to survive, aspire, and become.

    The first isolation and characterisation of infectious bronchitis (IB) viruses from poultry flocks in Morocco are reported. Five isolates designated D, E, F, H and M were related serologically to the Massachusetts serotype, while the sixth, isolate G, was found to be different from any previously reported serotype of IB virus. Neutralising antibodies to isolate G have been detected in sera collected from commercial flocks in Britain, although the virus has not been isolated. While all six isolates caused respiratory disease typical of IB in experimentally infected 3-week-old specified pathogen-free (SPF) chickens, isolate G was unusual in that it could be isolated from several parts of the alimentary tract for up to 21 days post inoculation, and from the duodenum up to 28 days. H120 vaccines protected chicks challenged with isolates E and F but not isolate G.

    We report here an evaluation of the dissemination of nim genes, encoding 5-nitroimidazoles resistance, among Bacteroides clinical strains isolated in Morocco. This study was done using a PCR method. Among 60 strains studied, nine contain a copy of a nim gene. The sequence determination of these genes showed that they are homologous to three nim genes previously characterized in strains isolated in France: nimB (five genes), nimC (three genes), and nimA (one gene). Although the nimA and nimC genes were previously identified on plasmids pIP417 and pIP419, respectively, we found here that they have a chromosomal location. The MICs of three 5-nitroimidazole antibiotics (metronidazole, ornidazole, and tinidazole) of the nim gene-containing strains were very low (0.5-2 microg/ml), indicating that the nim genes were not efficiently expressed in these clinical isolates.

    Both sexes of Onychogomphus boudoti sp. nov. Ferreira (Odonata: Anisoptera: Gomphidae) and exuviae are described and illustrated from a single locality in Morocco. This newly discovered species differs markedly from other Onychogomphus species by the morphology of the male epiproct and the female vulvar scale. It is genetically distinct in the mitochondrial DNA and the nuclear PRMT gene from all other Western Palaearctic Onychogomphus species. The known distribution of the new species is confined to a small stream with unusual habitat characteristics in the vicinity of Khenifra, in the Middle Atlas, where it experiences low population size and limited genetic diversity. We suggest listing this species both locally and globally as "Critically Endangered" [CR (B1, B2 + abiii)] following the IUCN Red List Categories and Criteria.

    During the monitoring programme of harmful algal blooms established along the south Atlantic coast of Morocco, a bimonthly determination of harmful algae and phycotoxins analysis in Perna perna was carried out from May 2003 to December 2004. Results of mouse bioassay (in organs and whole flesh) showed a seasonal evolution of paralytic shellfish poisoning (PSP) toxin. The mussel's contamination was associated with the occurrence in water of Alexandrium minutum. The PSP toxin profile obtained with high-performance liquid chromatography (HPLC/FD) revealed the dominance of gonyautoxins GTX2 and GTX3 and a minority of GTX1, GTX4 and saxitoxin (STX). This profile explains that the toxicity was mainly associated with A. minutum.

    The Topoiberia-Iberarray broad-band seismic network has covered in three successive legs the Iberian Peninsula and the Northern part of Morocco, allowing to acquire new seismological data with unprecedented resolution and coverage. One of the classical approaches used to infer information on the structure of the crust using passive seismic data is the inspection of the P-to-S conversions at the main discontinuities. In particular, the application of the H-K technique allows to evaluate the thickness and the mean Vp/Vs ratio for the crust beneath each available station. In this contribution, we benefit from the dense Topoiberia-Iberarray seismic network, with stations distributed on a regular 60 x 60 km grid, to obtain a detailed map of the Moho topography and the Vp/Vs variations beneath Iberia and Northern Morocco. This region show a great geodynamical diversity, including, North to South, crustal imbrication in the Pyrenean range, a large and relatively undisturbed Variscan Massif in the center of Iberia and areas of complex and still not completely understood geodynamics in the Alboran domain and the Atlas range. Beneath Northern Morocco, strong lateral variations of the crustal thickness are observed, depicting three domains: a previously unidentified thick crust (reaching at least 45 km) beneath the Rif, a thinned crust region beneath NE Morocco, with depths ranging from 22 to 30 km, and a region of 27-34 km thick crust in the Atlas domain and its foreland regions. Vp/Vs ratios show normal values close to 1.75 for most stations except for the Atlas domain, where several stations give low Vp/Vs ratios of around 1.71. Beneath Southern Iberia, the Moho show also significant variations. The highest values of crustal thickness in this region, reaching 46 km, are found under the External zones of the Betic range, near the contact with the Alboran Domain. Southeastern Iberia is affected by significant crustal thinning (from 19 km to 30 km) occurring over a short

    In the lagoon system of Moulay Bouselham, on the Atlantic coast of Morocco, drainage bring nutriments and sediments from irrigation systems to the open lagoon. The recent intensification of farming in the surrounding area is the chief cause of this. We studied the chemical pollution of the lagoon, which serves as a nature reserve, by analyzing the nitrate content of the water and the organochlorine pesticide content of the sediment. Comparison with similar ecosystems showed that the sediments were only moderately contaminated. However, the level of nitrates in the water was found to exceed the upper limit of the range of concentrations considered safe for human health in European regulations. The level of nitrate pollution in the area seems to be increasing, whereas organochloride pesticide pollution is on the decrease. The washing out of fertilizer during winter is responsible for much of the nitrate pollution in this season whereas in summer, urban effluents is the chief cause of nitrate contamination.

    An evaluation was made of the risk of contamination by faecal parasites in the population from the use of wastewater in agriculture. The study was based in 3 rural clusters in the northern region of Settat city, Morocco: 2 rural clusters exposed to untreated wastewater in agriculture and 1 not exposed. The sample comprised 333 people aged 3-60+ years: 214 exposed and 119 non-exposed. Stool samples were collected and examined for intestinal parasites. The results showed that the prevalence of intestinal parasitosis (i.e. evidence of at least 1 type of parasite) in the exposed group was significantly higher that the non-exposed group (66.4% versus 31.9%; relative risk 2.1). The household crowding index was also higher in the exposed group.

    This article studies the central role of nation-states in the Red Cross during the interwar period. In the late nineteenth century, Spain pioneered the creation of European-style humanitarian institutions in Morocco. However, its perennial instability as a state, aggravated by the colonial disaster of 1898, put an end to the regenerationist project of a Moroccan Red Cross. When the Spanish protectorate was established in 1912, the Spanish Red Cross was overshadowed by competition from its French counterpart, the internationalization of Tangiers and resistance from the local inhabitants. This culminated in the so-called Rif War of 1921-1927, a mixture of anticolonial revolt and international war that vividly exposed the ingrained deficiencies of the Spanish State and its Red Cross.

    The objective of this research was to estimate the attributable fraction (AF) of lung cancer linked to smoking in Morocco. The estimation was based on the SAMMEC (Adult Smoking-Attributable Mortality, Morbidity and Economic Costs) method based on the Levin formula to calculate AF linked to tobacco. Data about frequencies, association measures and relative risks were taken from available sources. The AF of lung cancer linked to smoking was about 87%, and around 3049 cases of this cancer in men could be avoided if tobacco use could be prevented. About a 10% reduction in smoking prevalence would result in a reduction of 346 lung cancer cases. Our study provides additional important elements for further advocacy to policy-makers to implement a tobacco control strategy based on a prevention policy in line with the epidemiological situation which could avoid a huge burden on the country.

    The Cambrian Tamdroust and Bab n'Ali Volcanic Complexes represent two magmatic episodes developed in the latest Ediacaran-Cambrian Atlas Rift of Morocco. Their rifting pulses were accompanied by accumulation of volcanosedimentary edifices (dominated by effusive lava flows in the former and explosive acidic aprons in the latter) associated with active tilting and uplift. Sealing of their peneplaned horst-and-graben palaeotopographies led to the onset of distinct onlapping geometries and angular discordances capping eroded basements ranging from the Ediacaran Ouarzazate Supergroup to the Cambrian Asrir Formation. Previous interpretations of these discordances as pull-apart or compressive events are revised here and reinterpreted in an extensional (rifting) context associated with active volcanism. The record of erosive unconformities, stratigraphic gaps, condensed beds and onlapping patterns across the traditional "lower-middle Cambrian" (or Cambrian Series 2-3) transition of the Atlas Rift must be taken into consideration for global chronostratigraphic correlation based on their trilobite content.

    This study evaluates the levels of nitrates and pesticides occurring in groundwater and agricultural soil in the Mnasra, Morocco area, a zone with intensive agricultural activity. A set of 108 water samples and 68 soil samples were collected from ten selected sites in the area during agricultural seasons, from May 2010 to September 2012. The results reveal that 89.7% of water samples exceeded the standard limit of nitrate concentrations for groundwater (50 mg/L). These results can be explained by the prevailing sandy nature of the soil in the area, the frequency of fertilizer usage, and the shallow level of the water table, which favors the leaching of nitrate from field to groundwater. In contrast, the selected pesticide molecules were not detected in the analysed soil and water samples; levels were below the quantification limit in all samples. This situation could be explained by the probable partial or total transformation of the molecules in soil.

    Summary Morocco has made significant strides in building its HIV research capacity. Based on a wealth of empirical data, the objective of this study was to conduct a comprehensive and systematic literature review and analytical synthesis of HIV epidemiological evidence in this country. Data were retrieved using three major sources of literature and data. HIV transmission dynamics were found to be focused in high-risk populations, with female sex workers (FSWs) and clients contributing the largest share of new HIV infections. There is a pattern of emerging epidemics among some high-risk populations, and some epidemics, particularly among FSWs, appear to be established and stable. The scale of the local HIV epidemics and populations affected show highly heterogeneous geographical distribution. To optimize the national HIV response, surveillance and prevention efforts need to be expanded among high-risk populations and in geographic settings where low intensity and possibly concentrated HIV epidemics are emerging or are already endemic.

    Gaining control over refugee flows and undocumented migrants currently dominate the media and political arenas in Europe. Underlying driving and enduring forces, such as employment-related migration pressure, tend to be relegated to the background. In this article, we explore migration pressure prospects up to 2035 in four countries with a tradition of emigration to Europe: Algeria, Morocco, Tunisia and Turkey. More specifically, we first derive a simple decomposition model based on the relationship between working-age population (WAP) growth and growth of gross domestic production (GDP) and worker productivity (GDP/W). From this model, we derive an indicator of migration pressure: size of the non-employed population in a country. This model is then used as framework for deriving storylines for three different scenarios of economic and demographic change up to 2035. Subsequently, storylines are operationalized, leading to scenario estimates of migration pressure up to 2035. The implications of the results are then discussed. Time series of macro-level economic and demographic data are used to underpin scenario assumptions. Scenario results suggest that in all countries employment ratios are expected to increase, but only in Tunisia is the size of the non-employed population-our indicator of migration pressure-expected to decline, irrespective of the scenario. Depending on the scenario, migration pressure remains high in Turkey and Morocco and may even become somewhat higher. The general conclusion is that in the long term, after 2035, labour migration pressure can be expected to decrease because the growth and size of the working-age population is decreasing while employment ratios are rising.

    The term 'Pan African' orogeny was first proposed in 1964 for a tectonothermal event in Africa ~ 500+/- 50 Ma. Over the past 50 years, the Pan African orogeny has been extended to as much as ~1050-450 Ma and recognized in other Gondwanan continents where regional names such as Brasiliano (South America), Adelaidean (Australian) and Bearmore (Antarctica) have been applied. The Pan African time span of ~500 million years is much longer than any Phanerozoic orogeny. However, it does correlate with time ranges of well defined Phanerozoic orogenic cycles such as the Appalachian cycle, extending from ~1,100 to 250 Ma, and the Cordilleran cycle of ~350 Ma to the present. A significant difference of course is that the Appalachian orogenic cycle has long been recognized as consisting of separate Grenville, Taconic, Acadian and Alleghenian orogenies. Similarly, the Mesozoic-Cenozoic Cordilleran orogenic cycle consists of distinct Antler, Sonoma, Nevadan, Sevier, Laramide and ongoing Cascadian-Andean orogenies. Until recently, the absence of precise geochronology in West Africa has prevented a more refined analysis of individual orogenic events within the Pan-African orogenic cycle. Since 2000, precision geochronologic dating by various researchers in the Anti-Atlas Mountains, Morocco, has provided critical data by which it is now appropriate to designate a Pan African orogenic cycle consisting of three separate orogenic events. We herein propose the following distinct orogenic events in the Anti-Atlas Mountains of Morocco: Iriri-Tichibanine orogeny (750-700 Ma), Bou Azzer orogeny (660-640 Ma) and the WACadomian orogeny (620-580 Ma).

    The emergence and the rapid spread of Pseudomonas aeruginosa carrying carbapenemases represent a serious threat to public health due to their delicate therapy. This work was performed to establish the resistance profile and to detect carbapenemases producing in 123 P. aeruginosa isolates. Among these 55 are environmental isolates and 68 are from the two major hospitals of Meknes-Tafilalet region in Morocco. All strains were tested against 14 antipseudomonal drugs by disc diffusion method. On carbapenem resistant strains minimum inhibitory concentrations of imipenem were determined by the E-test method. The modified Hodge test and EDTA tests were used for the detection of carbapenemases and metallo-β-lactamases (MBLs), respectively. PCR and DNA sequencing were conducted to detect carbapenemase-encoding genes and the enzyme types. 12% of isolates was susceptible to all antibiotics tested and Carbapenem resistance was observed in 33 P. aeruginosa isolates, 33.3% of them were multi-drug resistant. Among carbapenem resistant strains only two (6.1%) were positive for carbapenemases and also for MBLs. In addition to their resistance to almost all β-lactams tested, the MBLs producing strains were resistant to aminoglycosides. Molecular biology techniques confirmed the phenotypic results obtained for the two strains carbapenemase producers and demonstrated that each one of them carried blaVIM-2. The present study reports the first isolation of blaVIM genes in clinical isolates of P. aeruginosa in Morocco. Such isolates represent a serious emerging threat requiring strict hygiene measures to better control their spread.

    This study was undertaken in the Province of Sidi Kacem in northwest Morocco between April 2010 and March 2011. The main objective of the study was to determine the prevalence of Echinococcus granulosus (Eg) infection in owned dogs. This province was selected as a case study because of the social conditions, geographic and climatic diversity making it a model representative of many parts of Morocco. The survey was carried out in 23 rural communes and in the 5 municipalities (urban districts) of the Province and sampling was undertaken in randomly selected households. A total of 273 owned dogs comprising 232 from the 23 rural communes (rural dogs) and 41 from the 5 municipalities (urban dogs) were tested. Arecoline hydrobromide purgation was selected as the diagnostic method of choice to enable visualisation of expelled worms by dog owners, thereby imparting messages on the transmission mode of Eg to humans and farm animals. Of the 273 dogs tested, purgation was effective in a total of 224 dogs (82.1%). The overall estimated prevalence of Eg infection was 35.3% (79/224, 95% CI 22.3-47.0%). Dogs inhabiting rural communes were at greater risk of infection (38.0%, 95% CI 31.1-45.3%) than dogs roaming in municipalities or urban areas (18.8%, 95% CI 7.2-36.4%) and the prevalence of infection was higher in those inhabiting rural communes with slaughterhouses (62.7%, 95% CI 48.1-75.9%) than in communes without (29.1%, 95% CI 21.7-37.2%). This first assessment of Eg infection in Sidi Kacem Province indicates a key role of rural slaughterhouses in parasite transmission to dogs.

    The body structure and nutritional status of Moroccan women who have immigrated to Italy are examined here in relation to changes in their alimentary behaviors and life-styles, and compared with those of women living in Morocco, who still retain a traditional rural life-style. It is known that the choice to migrate to a foreign country may not only lead to conflicting situations, when the people involved encounter socio-cultural contexts which are very different from those of their original countries, but such choices may also involve severe consequences for health and nutritional status, following changes in alimentary behaviors and life-styles. Among groups recently migrated to Italy, the Moroccan-community is an appropriate reference to highlight these effects. The choice to examine women as the focus of this survey allows extension of observations of their nutritional behavior to the whole family group. According to the bio-indicators examined here, groups of immigrant women are quite different from those remaining at home. The former show a considerable increase in weight, as assessed by both anthropometric and impedentiometric parameters. More than one-third of Moroccan immigrant women are obese, to an extent well beyond that of women in Morocco. The cause of this difference is ascribed to quantitative and qualitative changes induced after migration. Migrant women tend to adopt a mixed diet, which includes both traditional food and that typical of the host country. However, there is a considerable increase in the use of prepared foods, such as pasta, among farinaceous products, and meat, although vegetables and fruit are also consumed. Moroccan women consider both their socio-economic status and alimentary behavior as very private matters--an attitude which makes it difficult to recruit them for this kind of research. Future interventions require their preliminary acceptance and involvement in research aims, to demonstrate its great importance in improving

    Coastal areas in the North of Morocco are at risk of tsunami inundation. Overland tsunami propagation leads to widespread and dramatic changes in coastal morphology due to sediments erosion, transport and deposition processes. Tsunami sediments transport and morphological changes must take into consideration bed-load and suspended load transport of non-cohesive sediments and suspended load of cohesive sediments. Numerical calculation of suspended sediment transport/deposition is performed by solving the advection-diffusion equations for the suspended sediment, where the velocities are obtained from the hydrodynamic modelling. In this study, we assess the morphological changes under tsunami impact at the Bay of Tangier-Morocco. We use a coupled hydrodynamic and morpho-dynamic numerical code, based on two open sources codes: COMCOT and Xbeach, to simulate the tsunami impact and the associated sediments transport and deposition. COMCOT solves the shallow water equations to calculate the inundation characteristics (flow depth and velocity), while Xbeach allows solving the advection-diffusion equations to determine the amount of sediments eroded, transported and deposed. The results of this study are presented in terms of maps displaying the amount of sediments eroded, transported and deposed at the bay of Tangier following a tsunami similar to the 1755 Lisbon event. We find that the bay of Tangier is vulnerable to morphological changes under tsunami threat coming from SW Iberia margin.

    This work is based on the compilation and re-evaluation of the most significant data, either personal or from the literature, concerning the Moroccan Variscides. The latter constitute the only, moderately disturbed or even undisturbed part of the South-Western Branch of the Variscan Belt, facing directly NW Gondwana. They include two orogenic segments, namely the northern Mauritanides and the Meseta Domain exposed in the Saharan and Atlas-Meseta regions respectively, and a foreland belt cropping out essentially in the Anti-Atlas. The eastward thrust units of Saharan Morocco (Oulad Dlim) mostly originate from the West African Craton (WAC) border in an area of thin Palaeozoic sedimentation. Thin-skinned fold-thrust foreland arcs develop progressively northward (Zemmour) at the expense of the increasingly thick Palaeozoic series, whereas thick-skinned deformation characterizes the inverted proximal paleomargin in the Anti-Atlas Domain. As suggested by the Meseta and Anti-Atlas stratigraphic similarities, the Meseta Domain corresponds to a collage of moderately displaced, thinned crustal blocks from the distal Gondwana paleomargin. Variscan deformation is dominated by NW-verging thrusts, and metamorphism developed in the thickened tectonic prism in relation with crustal anatexis at depth. The Meseta-Anti-Atlas boundary is a major, ENE-trending transpressional dextral fault referred to as the South Meseta Fault (SMF). Discussing the correlations between the Variscan segments of Morocco and SW Iberia allows us to suggest that a latitudinal transform zone similar to the SMF separated these segments during the Late Palaeozoic. Subduction of the Rheic Ocean crust would have been directed SE-ward along both the Iberian and Moroccan Meseta, and NW-ward south of the SMF, i.e. along the WAC.

    Background Stroke is a growing public health concern in low- and middle- income countries. Improved knowledge about the association between socioeconomic status and stroke in these countries would enable the development of effective stroke prevention and management strategies. This study presents the association between socioeconomic status and the prevalence of stroke in Morocco, a lower middle-income country. Methods Data on the prevalence of stroke and stroke-related risk factors were collected during a large population-based survey. The diagnosis of stroke in surviving patients was confirmed by neurologists while health, demographic, and socioeconomic characteristics of households were collected using structured questionnaires. We used Multiple Correspondence Analysis to develop a wealth index based on characteristics of the household dwelling as well as ownership of selected assets. We used logistic regressions controlling for multiple variables to assess the statistical association between socioeconomic status and stroke. Findings Our results showed a significant association between household socioeconomic status and the prevalence of stroke. This relationship was non-linear, with individuals from both the poorest (mainly rural) and richest (mainly urban) households having a lower prevalence of stroke as compared to individuals with medium wealth level. The latter belonged mainly to urban households with a lower socioeconomic status. When taking into account the urban population only, we observed that a third of poorest households experienced a significantly higher prevalence of stroke compared to the richest third (OR = 2.06; CI 95%: 1.09; 3.89). Conclusion We conclude that individuals from the most deprived urban households bear a higher risk of stroke than the rest of the population in Morocco. This result can be explained to a certain extent by the higher presence of behavioral risk factors in this specific category of the population, which leads in

    Paleomagnetic data able to constrain the paleoposition of the West African Craton (WAC) during Paleo-Mesoproterozoic are absent, mainly due to gaps on the sedimentary record and intense remagnetizations. Dykes that intrude several Proterozoic inliers of WAC in the Anti-Atlas Belt (southern Morocco) have recently been subjected to geochronological studies, which revealed ages between Paleoproterozoic and early Neoproterozoic. Therefore, these dykes represent a window of opportunity for paleomagnetic studies aiming to infer about the paleoposition of WAC during Proterozoic. On this scope we conducted a paleomagnetic study on seven Proterozoic dykes of the Iguerda inlier. We determined the paleomagnetic directions and evaluated their meaning by rock magnetic and mineral analyses, complemented by petrographic observations. Results revealed that these rocks record the presence of a complex history of remagnetization events, mostly assigned to several Phanerozoic thermal/chemical events. In particular, we found components assigned to the late stages of Pan African orogeny (s.l.), to the Late Carboniferous Variscan orogeny, and to more recent events. The recognized remagnetization processes are related to widespread metamorphic events under greenschist facies followed by low-temperature oxidation, both responsible for the formation of new magnetic phases (magnetite and hematite). The primary (magmatic) thermo-remanent magnetization of the dykes was obliterated during these events through multiple thermal and chemical remagnetizations. For only one dyke the presence of primary magnetization is possible to infer, though not to confirm, and would place WAC at an equatorial position around 1750 Ma.

    Aims Understanding type 2 diabetes mellitus is critical for designing effective diabetes prevention policies in Qatar and the Middle East. Methods Using the Qatar 2012 WHO STEPwise approach to surveillance survey, a subsample of 1224 Qatari participants aged 18–64 years was selected. Subjects had their fasting blood glucose levels tested, had not been diagnosed with or treated for diabetes, had a fasting time >12 hours and were not pregnant. We applied a hypothesized structural equation model (SEM) to assess sociodemographic, behavioral, anthropometric and metabolic variables affecting persons with type 2 diabetes mellitus. Results There is a direct effect of triglyceride levels (0.336) and body mass index (BMI) (0.164) on diabetes status. We also found that physical activity levels negatively affect BMI (−0.148) and positively affect high-density lipoprotein (HDL) (0.106); sociodemographic background negatively affects diet (−0.522) and BMI (−0.352); HDL positively affects total cholesterol (0.230) and has a negative effect on BMI (−0.108), triglycerides (−0.128) and waist circumference (−0.104). Diet has a positive effect on triglycerides (0.281) while family history of diabetes negatively affects total cholesterol (−0.104). BMI has a positive effect on waist circumference (0.788) and mediates the effects of physical activity over diabetes status (−0.028). BMI also mediates the effects that sociodemographic factors (−0.058) and physical activity (−0.024) have on diabetes status. BMI and HDL (−0.002) together mediate the effect of physical activity on diabetes status and similarly HDL and tryglycerides (−0.005) also mediate the effect of physical activity on diabetes status. Finally diet and tryglycerides mediate the effects that sociodemographic factors have on diabetes status (−0.049). Conclusions This study's main finding is that triglyceride levels and BMI are the main variables directly affecting diabetes status in the Qatari

    Salmonella enterica is one of the most commonly reported causes of bacterial foodborne illness around the world. Understanding the sources of this pathogen and the associated factors that exacerbate its risk to humans will help in developing risk mitigation strategies. The genetic relatedness among Salmonella isolates recovered from human gastroenteritis cases and food animals in Qatar were investigated in the hope of shedding light on these sources, their possible transmission routes, and any associated factors. A repeat cross-sectional study was conducted in which the samples and associated data were collected from both populations (gastroenteritis cases and animals). Salmonella isolates were initially analyzed using multi-locus sequence typing (MLST) to investigate the genetic diversity and clonality. The relatedness among the isolates was assessed using the minimum spanning tree (MST). Twenty-seven different sequence types (STs) were identified in this study; among them, seven were novel, including ST1695, ST1696, ST1697, ST1698, ST1699, ST1702, and ST1703. The pattern of overall ST distribution was diverse; in particular, it was revealed that ST11 and ST19 were the most common sequence types, presenting 29.5% and 11.5% within the whole population. In addition, 20 eBurst Groups (eBGs) were identified in our data, which indicates that ST11 and ST19 belonged to eBG4 and eBG1, respectively. In addition, the potential association between the putative risk factors and eBGs were evaluated. There was no significant clustering of these eBGs by season; however, a significant association was identified in terms of nationality in that Qataris were six times more likely to present with eBG1 compared to non-Qataris. In the MST analysis, four major clusters were presented, namely, ST11, ST19, ST16, and ST31. The linkages between the clusters alluded to a possible transmission route. The results of the study have provided insight into the ST distributions of S. enterica and

    In Morocco, the Marrakech-Tensift-Al Haouz region is one of the 16 regions most affected by poisoning. The aim of this study was to determine the epidemiological profile of poisoning recorded in the study region. A retrospective study of poisoning cases, declared between 1981 and 2008 in the Morocco Poison Control and Pharmacovigilance Center, was conducted. During the study period, 8517 poisoning cases were collected. The average age of patients was 22 ± 15 years. The male/female sex ratio was 0.85. Food poisoning was the most reported in the region, with 26.6% of cases. Among the 2,779 patients for whom the outcome was known, 65 died, with lethality rate of 23.4‰. The maximum lethality rate was recorded among those poisoned by paraphenylenediamine (170.7‰).

    Brucellosis is one of the most widespread zoonoses in the world caused by several species of the genus Brucella. The disease, eradicated in many developed countries, is a re-emerging neglected zoonosis endemic in several zones especially in the Mediterranean region, impacting on human health and livestock production. A One Health approach could address brucellosis control in Morocco but scarcity of reliable epidemiological data, as well as underreporting, hinders the implementation of sustainable control strategies. Surveillance and control policies implemented by the Moroccan government in domestic animals (cattle and small ruminants) in the last few decades are assessed for disease impact. This study considers the origins of animal brucellosis in Morocco and the potential for emergence of brucellosis during a shift from extensive to intensive livestock production.

    At least three distinctive cycles are preserved in the carbon-isotope patterns for the Vendian/Tommotian interval for the Siberian platform and the Anti-Atlas Mountains of Morocco. In Siberia, and early Tommotian carbon cycle provides the first detailed test of correlations based on archaeocyathid biostratigraphy between classic sequences on the Aldan and Lena rivers, and demonstrates that the Early Cambrian zone boundaries are reasonably good time lines. The carbon signal is preserved in both limestone and dolomite and across regional facies variations. The {delta}{sup 13}C results from the late Vendian section in Morocco display a pattern similar to that found in Siberia, suggesting that carbon isotopes can be used to test stratigraphic correlations on an intercontinental scale.

    Objective. To assess pharmacy students' knowledge and perceptions of doping and anti-doping in sports and to explore the curricular needs for undergraduate pharmacy in the field of sports pharmacy. Methods. A cross-sectional, descriptive, web-based survey of pharmacy students was conducted at Qatar University College of Pharmacy from March to May 2014. Data were analyzed using descriptive and inferential statistics. Results. Eighty respondents completed the online survey (80% response rate). Sixty percent were unaware of the World Anti-Doping Agency, and 85% were unaware of the International Pharmaceutical Federation's statement on the pharmacist's role in anti-doping. Students' knowledge score regarding the prohibited status of drugs that may be used by athletes was around 50%. Fourth-year pharmacy students had significantly higher knowledge scores than the other groups of students. Respondents acknowledged the important role of health care professionals, including pharmacists, as advisors on the safe and effective use of drugs in sports. Ninety percent of the students supported the inclusion of sports pharmacy in the curriculum. Conclusion. Pharmacy students indicated a strong desire to play a role in doping prevention and ensure safe and rational use of drugs among athletes. They suggested requiring an education and training strategy for sports pharmacy in undergraduate pharmacy curricula.

    This study examines the lack of a noticeable indigenous labor movement in the contemporary Gulf Arab countries of Bahrain, Kuwait and Qatar; it focuses on the emergence, after the discovery of oil, of an industrial Gulf labor force, and on the evolution of the British policy towards oil and Gulf oil workers. The period examined begins with the discovery of oil in Bahrain in 1932 (the first such discovery on the Arab side of the Gulf), and ends with the Suez Crisis of 1956. The latter is a watershed event in Gulf history. It is argued that the Suez Crisis was in large part responsible for the long-term defeat of the indigenous labor movement in the Gulf. Attention is given to the parts played by the British Government of India, the Foreign Office, the local Shaikhs, the Gulf nationalists, and by the workers themselves. Policies towards workers passed through two different periods. In the first, 1932-1945, the Government of India had no direct interest in the Gulf labor situation; in the second, 1946-1956, the Foreign Office took increased interest in the welfare of local oil workers, primarily because of the importance of oil to reconstruction of the British economy after the war. However, the Suez Crisis in 1956 convinced the British to withdraw their support for the workers.

    In Morocco, cutaneous leishmaniasis (CL) caused by Leishmania (L.) tropica is a major public health threat. Strains of this species have been shown to display considerable serological, biochemical, molecular biological and genetic heterogeneity; and Multilocus Enzyme Electrophoresis (MLEE), has shown that in many countries including Morocco heterogenic variants of L. tropica can co-exist in single geographical foci. Here, the microsatellite profiles discerned by MLMT of nine Moroccan strains of L. tropica isolated in 2000 from human cases of CL from Chichaoua Province were compared to those of nine Moroccan strains of L. tropica isolated between 1988 and 1990 from human cases of CL from Marrakech Province, and also to those of 147 strains of L. tropica isolated at different times from different worldwide geographical locations within the range of distribution of the species. Several programs, each employing a different algorithm, were used for population genetic analysis. The strains from each of the two Moroccan foci separated into two phylogenetic clusters independent of their geographical origin. Genetic diversity and heterogeneity existed in both foci, which are geographically close to each other. This intra-focal distribution of genetic variants of L. tropica is not considered owing to in situ mutation. Rather, it is proposed to be explained by the importation of pre-existing variants of L. tropica into Morocco.

    The High Atlas and the Anti Atlas are fold-belts linked to former and still ongoing continent-continent collisions. Despite their high elevation, studies indicate a lack of a deep crustal root (<40 km) while the lithosphere underneath is thinned (<100 km). Previous explanations for this thinning include asthenospheric upwelling due to small-scale convection or a small plume. We use data recorded at stations in SW Morocco to analyse teleseismic P- and S-wave receiver functions. Our study yields a crustal thickness ranging from 24 km near the Atlantic coast to 44 km beneath the High Atlas with an average crustal Vp/Vs ratio of 1.77 in the entire region. A crustal thickness of 40 km cannot entirely support the topography in this region. Furthermore, we find the lithosphere-asthenosphere boundary at ˜80 km depth. The lithosphere beneath SW Morocco is thinner than beneath northern Morocco (>150 km). This lithospheric thinning supports the theory of thermal compensation of the mountain ranges. The mantle transition zone thickness amounts to 240 ± 10 km. The transition zone seems to be slightly thinned which might indicate a higher mantle temperature in this region.

    2016-03-01

    This study explores the origins and consequences of a unique, secret, French-American collaboration to prospect for uranium in 1950s Morocco. This collaboration permitted mediation between the United States and France. The appearance of France in an American-supported project for raw nuclear materials signalled American willingness to accept a new nuclear global order in which the French assumed a new, higher position as regional nuclear ally as opposed to suspicious rival. This collaboration also permitted France and the United States to agree tacitly to the same geopolitical status for the French Moroccan Protectorate, a status under dispute both in Morocco and outside it. The secret scientific effort reassured the French that, whatever the Americans might say publicly, they stood behind the maintenance of French hegemony in the centuries-old kingdom. But Moroccan independence proved impossible to deny. With its foreseeable arrival, the collaboration went from seductive to dangerous, and the priority of American and French geologists shifted from finding a major uranium lode to making sure that nothing was readily available to whatever post-independence interests might prove most powerful. Ultimately, the Kingdom of Morocco took a page out of the French book, using uranium exploration to assert sovereignty over a different disputed territory, its de facto colony of the Western Sahara.

  11. A sheeppox outbreak in Morocco: isolation and identification of virus responsible for the new clinical form of disease

    PubMed Central

    2014-01-01

    Background Sheeppoxvirus (SPPV) is a member of the Capripoxvirus genus of the Poxviridae family, which causes significant economic losses in Morocco. The resurgence of the sheeppox disease during 2010 was characterized by an emergence of a classical nodular form for the first time in Morocco. However, little is known about the virus strain responsible for nodular form. In this study, thirty three sheep, from the eastern region of Morocco, clinically infected were examined and dead animals were autopsied. A rapid diagnostic assay for SPPV using different type of clinical samples would be useful for outbreak management. The aim of this work was to isolate the virus strain responsible for nodular form and we identified and compared by phylogenetic analysis the field strain with Moroccan vaccine strain targeting the thymidine kinase (TK) gene and the chemokine analogue receptor of interleukin (IL8) gene. Further, it was important to investigate and validate a real-time PCR using different clinical and post-mortem samples to manage epidemic sheeppox disease. Results The nodular form of sheeppox disease observed in Morocco was clinically characterized by fever, depression, lacrimation, diarrhea in lambs and nodule. At necropsy, the most affected organ was the lung. The etiological strain was successfully isolated from lung nodule in a dead lamb and was identified by using real-time PCR that has been tested and validated on different types of clinical and post mortem samples from naturally infected animals. Sequence and phylogenetic analysis of TK and IL8 gene showed that there was a very close relationship between field and vaccine strain. They were clustered within other SPPV strains. Conclusion In the current study, we show for the first time the nodular form of sheeppox in Morocco. We demonstrate a robust real-time PCR-based diagnostic assay to detect the sheeppox virus in multiple sample that can be implemented to efficiently manage the disease outbreak. Our study

  12. Sexual violence and sub-Saharan migrants in Morocco: a community-based participatory assessment using respondent driven sampling

    2014-01-01

    Background The European Union contracted Morocco to regulate migration from so-called “transit migrants” from Morocco to Europe via the European Neighbourhood Policy. Yet, international organisations signal that human, asylum and refugee rights are not upheld in Morocco and that many sub-Saharan migrants suffer from ill-health and violence. Hence, our study aimed at 1) investigating the nature of violence that sub-Saharan migrants experience around and in Morocco, 2) assessing which determinants they perceive as decisive and 3) formulating prevention recommendations. Methods Applying Community-Based Participatory Research, we trained twelve sub-Saharan migrants as Community Researchers to conduct in-depth interviews with peers, using Respondent Driven Sampling. We used Nvivo 8 to analyse the data. We interpreted results with Community Researchers and the Community Advisory Board and commonly formulated prevention recommendations. Results Among the 154 (60 F-94 M) sub-Saharan migrants interviewed, 90% reported cases of multiple victimizations, 45% of which was sexual, predominantly gang rape. Seventy-nine respondents were personally victimized, 41 were forced to witness how relatives or co-migrants were victimized and 18 others knew of peer victimisation. Severe long lasting ill-health consequences were reported while sub-Saharan victims are not granted access to the official health care system. Perpetrators were mostly Moroccan or Algerian officials and sub-Saharan gang leaders who function as unofficial yet rigorous migration professionals at migration ‘hubs’. They seem to proceed in impunity. Respondents link risk factors mainly to their undocumented and unprotected status and suggest that migrant communities set-up awareness raising campaigns on risks while legal and policy changes enforcing human rights, legal protection and human treatment of migrants along with severe punishment of perpetrators are politically lobbied for.

    The evolution of the Moroccan Atlantic rifted margin is marked by a period of abnormal and excessive early post-rift subsidence during the Late Jurassic-Early Cretaceous affecting the proximal coastal basins, the continental shelf and the distal deep basins, which acted coevally to km-scale uplift and erosion of large domains to the east. The tectonics of the uplift event are still unclear, as it took place 30 to 50 Myr after lithospheric breakup between Morocco and Nova Scotia and prior to the Atlas/Alpine contraction, which gave rise to the Atlas and the Rif mountain belts. The Essaouira-Haha basin, located on the coastal plain of the Atlantic rifted margin of Morocco, and bounded by two uplifted Paleozoic basement highs (i.e. the Massif Ancien of Marrakech, to the east, and the Jebilet, to the northeast), is an ideal location to investigate the tectonic processes that might have triggered these vertical movements. Although most of the deformation observed in the basin is classically attributed to Upper Cretaceous halokinesis and Neogene Atlas contraction, recent works have shown the existence of contractional structures. We carry out a structural analysis of the Jbel Amsittene Anticline, located in the middle of the Essaouira-Haha basin to investigate the tectonics of its formation and its relationship with the above-mentioned exhumation. We show structural field data along several cross-sections transecting the anticline, and characterize a salt-cored fault propagation fold verging north, with a Triassic salt acting as a detachment plane. Regional kinematic indicators and structures show overall NNW-SSE to NNE-SSW shortening and active tectonics during the postrift phase, as indicated by syn-tectonic wedges seen for the Late Jurassic to Early Cretaceous period. These facts discard the "salt-drives-tectonics" theory to let "tectonic-drives-salt" one to rise, and point to factors other than small-cell mantle convection acting during the evolution of the Moroccan

    The most characteristic topographic features of Morocco are the Atlas Mountains and the Rif Coordillera. These two orogenic belts are the response of different geodynamic processes acting at lithospheric scale caused by a unique driver, the collision between two tectonic plates. Both are located within the diffuse plate boundary zone separating Africa and Europe. The boundary zone is characterized by a relatively broad zone of deformation that includes Mountain chains in southern Iberia, the Betics and the Rif cordillera in Morocco. The zone delineates the arcuate arc system of Gribraltar. Within the last decade a large international effort have been devoted to the area mostly leaded by Spanish groups with the collaboration of international research teams (including scientist form Europe and USA). Key multi-seismic projects have been developed that aim to constrain the structure, composition and tectonic scenario from south of the Atlas to the Betics, across the Rif cordillera and the Alboran basin. The multidisciplinary research program includes: natural source (earthquakes) recording with temporal deployments of broad band (BB) instrumentation and, controlled source seismic acquisition experiments where, spatially dense recording of wide-angle seismic reflection shot gathers were acquired. The passive experiments consisted on: a transect from Merzouga across the Gibraltar arc and into the Iberian peninsula (untill south of Toledo); a nearly regular grid of BB which was achieve by multiple deployments of a number of BB. The controlled source datasets were able to constrain the crustal structure and provide seismic P-wave propagation velocity models from the coast across the Rif and the Atlas. Travel-time inversion of the controlled source seismic data across the Atlas constraints a crustal root to the south of the High Atlas, and reveals mantle wedge. A limited crustal imbrication also appears in the Middle Atlas. The crustal thickness, does not exceeded 40 km in

    With precipitations close to 227 mm/year in average, the coastal region of south Morocco presents a chronically shortage of drinkable and fresh water. Since 1994, in the Mirleft area (150 km south of Agadir), inhabitants are facing a critically drought event. In the year 2007, only 49 mm of rain was recorded. However, measurements in Mirleft in the same year, showed that the dew yield was on order of 40 % of rain fall. In order to show to the local population the interest of recovering dew water in addition to rain water, a small nearby village (Idouasskssou, 8 km SE of Mirleft) was equipped with three pilot condensers of 136 m2 total surface area. In order to ensure a good integration of the project by the village inhabitants, a local organization (Association IMRJANE) collaborated to the project. A concrete tank at ground level with a flat horizontal surface, easily accessible for inhabitants and also a model for traditional Morocco terrace roofings, has been equipped with two lines of condensers (40.6 m²). All roofing materials were from local shops. Only the special radiative and hydrophilic coating was coming from non local resources (see www.opur.fr). The top of a second tank (aside the first one) was renovated and covered with a 21.2 m² two slopes steel roof, insulated and painted with the special dew coating as above. These roofs represent a condensation surface comparable to that of a very little house. A third condenser, with 73.8 m² surface area, was implemented directly on the ground, ensuring minimal work and very cheap implementation costs. Dew was collected and measured in one of the concrete tanks. The water production during 6 months, from 15-12-2008 to 31-07-2009 (137 dew events, 47 % of days) was more than 3800 L (more than 0.2 mm/dew day). It is important to note that, while the devices are specifically designed to condense dew water, they also harvest rain and fog as well, thus providing to the population a valuable water resource.

    Roughly 15 years ago it was discovered that substantial parts of the Morocco passive continental margin experienced km-scale, post-rift exhumation. It was predicted that the sands resulting from the associated erosion would be present in the offshore and potentially form hydrocarbon reservoirs. At the same time, anomalous post-rift vertical movements have been documented in various localities of the world and rifted continental margins are at present exciting objects of research. Following intense research efforts the knowledge of the kinematics of vertical movements and their implications for sedimentary systems is increasing. The low-T geochronology initially limited to the classical Meseta-Massif Ancien de Marrakech transect has been expanded reaching the Reguibate Massif to the S and covering, possibly more importantly, one transect in E-W direction along the Anti Atlas. Exhumation occurred along two dominant trends. In N-S direction a several hundred-kilometers long exhuming domain developed roughly parallel to the Atlantic margin. Changes in magnitude and timing of exhumation are observed along this elevated domain associated with E-W trending undulations. The timing of main stage of upward movement of E-W trending highs seems to be Late Jurassic-Early Cretaceous in the Meseta and High Atlas and somewhat older, Early to Middle Jurassic, in the Anti-Atlas and Reguibate. The discovery of E-W trending highs and lows has major implication for sediment distribution and dispersal. At the large scale, it means that the drainage basins were smaller than initially predicted. This seems to be compatible with the paucity of sands encountered by recent exploration wells drilled offshore Morocco. At the scale of several kilometers, W-E trending anticlines and synclines developed in a generally subsiding coastal environment. These folds often had an expression at the sea floor documented by ravinement surfaces and (Jurassic) reef build-ups on top of the anticlines

  17. Simulating Evapotranspiration In The DrÂa Valley, Southern Morocco: Model Sensitivity To Surface Properties

    Hübener, H.; Sogalla, M.; Kerschgens, M.

    Within the interdisciplinary project IMPETUS (an integrated approach to the efficient management of scarce water resources in West Africa) the effect of interaction be- tween the earth's surface and atmosphere on fresh water availability is investigated. In this study the focus is laid upon model studies for for regions north and south of the Sahara. At the high-resolution end of the meteorological model chain employed in IMPETUS, simulations with the non-hydrostatic mesoscale model FOOT3DK (Flow Over Orographically structured Terrain, 3-Dimensional, Cologne-version) are carried out for two subcatchments in Morocco and Benin. The main objectives are: 1) to estab- lish high-resolution, area covering data-sets of evaporation, precipitation and related quantities, and 2) to assess the sensitivity of the atmospheric branch of the hydro- logical cycle to variations in the land surface. For this purpose, FOOT3DK is nested into the Local-Model (LM) of the German Weather Service (DWD), which is used for episode simulations within IMPETUS. For a first case study sensitivity tests have been carried out with FOOT3DK on 3 km horizontal resolution for the mid and lower Drâa valley in Morocco, south of the Atlas mountains. Special emphasis is given to response of the model to heterogeneities in soil water content and in soil type. Considering the response to heterogeneities in soil water content, two different methods were used to artificially enhance the water ressources available for transpiration. Results show not only enhanced transpiration rates, but also changes in near surface atmospheric flow patterns. This is due to stabilisation of the atmosphere on account of reduced near surface temperatures associated with enhanced evapotranspiration. To examine the model sensitivity to soil types, the uniform soil type taken from LM-simulations is replaced by a more realistic height dependent soil type distribution. Simulations show only small sensitivity to these changes

    SummaryTwo coastal sites were investigated in an arid region of southwest Morocco to determine the amount of dew, fog and rain that could be collected from rooftops for household use. Systematic measurements were performed in Mirleft (43 m asl, 200 m from the coast) for 1 year (May 1, 2007 to April 30, 2008) and in Id Ouasskssou (240 m asl, 8 km from the coast) for three summer months (July 1, 2007 to September 30, 2007). Dew water was collected using standard passive dew condensers and fog water by utilizing planar fog collectors. The wind flow was simulated on the rooftop to establish the location of the fog collector. At both sites, dew yields and, to a lesser extent, fog water yields, were found to be significant in comparison to rain events. Mirleft had 178 dew events (48.6% of the year, 18 ± 2 L m-2 cumulated amount) and 20 fog episodes (5.5% of the year, 1.4 L m-2 with uncertainty -0.2/+0.4 L m-2 cumulated amount), corresponding to almost 40% of the yearly rain contribution (31 rain events, 8.5% of the year, 49 ± 7 mm cumulated amount). At Id Ouasskssou there were 50 dew events (7.1 ± 0.3 L m-2, 54.3% frequency), 16 fog events (6.5 L m-2 with uncertainty -0.1/+1.8 L m-2, 17.4% frequency) and six rain events (16 ± 2 mm, 6.5% frequency). Meteorological data (air and dew point temperature and/or relative humidity, wind speed and wind direction, cloud cover) were recorded continuously at Mirleft to assess the influence of local meteorological conditions on dew and fog formation. Using the set of collected data, a new model for dew yield prediction based on artificial neural networks was developed and tested for the Mirleft site. This model was then extrapolated to 15 major cities in Morocco to assess their potential for dew water collection. It was found that the location of the cities with respect to the Atlas mountain chain, which controls the circulation of the humid marine air, is the main factor that influences dew production.

  19. Botanical identification of medicinal roots collected and traded in Morocco and comparison to the existing literature

    2013-01-01

    Background A literature review revealed heavy reliance on a few key publications for identification of medicinal plant species from local or vernacular names and a lack of citation of voucher specimens in many publications. There is a need for more reliable and standardized data on the identity of species used for medicine, especially because local names vary from region to region. This is especially true in the case of medicinal roots, for which identification of species is difficult. This paper contributes to existing data on the species sold as medicinal roots (and other underground plant parts such as bulbs, corms, rhizomes and tubers) in Morocco. Methods Data were collected in collaboration with herbalists in Marrakech and collectors in rural regions near Marrakech where species are collected from the wild. The ethno-medicinal uses of these species were also recorded. Results We identified the vernacular names for 67 medicinal roots (by free listing) used to treat a variety of human diseases. We were able to collect and identify one or more species for 39 of the recorded vernacular names. The ones we were not able to identify were either imported or no longer available in the markets. We collected more than one species for some of the vernacular names for a total of 43 species. We identified six new vernacular names and four species which had not been previously described in the literature. Our botanical identification matched at least one of the names listed in the literature 63% of the time and did not match any species listed in the literature 37% of the time. Of the three most commonly cited pieces of literature we compared to, we found the greatest overlap with the broader, more comprehensive work of Bellakhdar 1997 (as opposed to Benchâabane and Abbad 1997 which worked in a similarly focused geographical area). However there was only 63% agreement between Bellakhdar 1997 and our botanical identifications, and 29% of the time our identification didn

    Soil salinization is major environmental issue in irrigated agricultural production. Conventional methods for salinization monitoring are time and money consuming and limited by the high spatiotemporal variability of this phenomenon. This work aims to propose a spatiotemporal monitoring method of soil salinization in the Tadla plain in central Morocco using spectral indices derived from Thematic Mapper (TM) and Operational Land Imager (OLI) data. Six Landsat TM/OLI satellite images acquired during 13 years period (2000-2013) coupled with in-situ electrical conductivity (EC) measurements were used to develop the proposed method. After radiometric and atmospheric correction of TM/OLI images, a new soil salinity index (OLI-SI) is proposed for soil EC estimation. Validation shows that this index allowed a satisfactory EC estimation in the Tadla irrigated perimeter with coefficient of determination R2 varying from 0.55 to 0.77 and a Root Mean Square Error (RMSE) ranging between 1.02 dS/m and 2.35 dS/m. The times-series of salinity maps produced over the Tadla plain using the proposed method show that salinity is decreasing in intensity and progressively increasing in spatial extent, over the 2000-2013 period. This trend resulted in a decrease in agricultural activities in the southwestern part of the perimeter, located in the hydraulic downstream.

    Background There is wide variation in clinical presentation and outcome of lupus nephritis (LN) among different ethnic groups. Few data for LN exist on North Africans, especially those from Morocco. The aim of our study was to review retrospectively the features and outcome of LN in Moroccan patients. Patients and methods We performed a single-center retrospective study. A total of 114 patients with LN were included. All patients met American Rheumatism Association criteria. LN was classified according to the International Society of Nephrology/Renal Pathology Society classification. We adopted previously defined outcome criteria for LN. Results There were 101 females and 13 males, with a mean age of 29.9 years. At first presentation, we noted hypertension in 33%, hematuria in 76%, nephrotic syndrome in 53%, and renal failure in 60% of cases. Renal biopsy revealed predominant proliferative classes in more than 80% of patients. Patients received different regimens mainly based on intravenous cyclophosphamide. After a mean follow-up of 22 months, remission occurred in 45.5%, relapses in 82%, end-stage renal failure in 21%, and death in 16% of cases. Infection and neurological and cardiovascular diseases were the most frequent causes of death. Conclusion LN seems to be severe in our study, with a predominance of proliferative forms, severe renal manifestations, and poor renal and overall survival. PMID:24294005

    Seventy bacterial strains were isolated from root nodules of the legume Hedysarum flexuosum grown wild in soils from Northwest Morocco. Repetitive extragenic palindromic (REP)-polymerase chain reaction (PCR) clustered the strains into 30 REP-PCR groups. The nearly complete sequence of the 16S rRNA gene from a representative strain of each REP-PCR pattern showed that 17 strains were closely related to members of the genus Rhizobium of the family Rhizobiaceae of the Alphaproteobacteria. Pairwise alignments between globally aligned sequences of the 16S rRNA gene indicated that the strains from H. flexuosum had 99.75-100% identity with Rhizobium sullae type strain IS123(T). The phenotypic characteristics analyzed allowed description of a wide physiological diversity among the isolates, where the carbohydrate assimilation test was the most discriminating. Analysis of the 16S rRNA gene of a representative strains from the remaining 13 REP-PCR groups showed they belong to a wide variety of phylogenetic groups being closely related to species of genera Stenotrophomonas, Serratia, Massilia, Acinetobacter, Achromobacter, and Pseudomonas from the Beta- and Gammaproteobacteria. The R. sullae strains identified in this study produced effective symbiosis with their original host plant. None of the other bacterial strains could form nodules on H. flexuosum.

    The Kem Kem beds in South Eastern Morocco contain a rich early Upper (or possibly late Lower) Cretaceous vertebrate assemblage. Fragmentary remains, predominantly teeth and jaw tips, represent several kinds of pterosaur although only one species, the ornithocheirid Coloborhynchus moroccensis, has been named. Here, we describe a new azhdarchid pterosaur, Alanqa saharica nov. gen. nov. sp., based on an almost complete well preserved mandibular symphysis from Aferdou N'Chaft. We assign additional fragmentary jaw remains, some of which have been tentatively identified as azhdarchid and pteranodontid, to this new taxon which is distinguished from other azhdarchids by a remarkably straight, elongate, lance-shaped mandibular symphysis that bears a pronounced dorsal eminence near the posterior end of its dorsal (occlusal) surface. Most remains, including the holotype, represent individuals of approximately three to four meters in wingspan, but a fragment of a large cervical vertebra, that probably also belongs to A. saharica, suggests that wingspans of six meters were achieved in this species. The Kem Kem beds have yielded the most diverse pterosaur assemblage yet reported from Africa and provide the first clear evidence for the presence of azhdarchids in Gondwana at the start of the Late Cretaceous. This, the relatively large size achieved by Alanqa, and the additional evidence of variable jaw morphology in azhdarchids provided by this taxon, indicates a longer and more complex history for this clade than previously suspected.

    Intestinal parasites are common in the Moroccan population. Enteroparasites in children from four schools in urban and rural areas of Tetouan (Morocco) were studied to treat these children and to design prevention and control programs. A total of 673 children were examined. The prevalence of parasitized children was 51%. The average number of enteroparasites was half in urban areas than in rural areas. Multiple parasitism appeared in 30% of the samples presenting two, three, or four parasites. The most prevalent parasite was Blastocystis hominis (64%). Giardia duodenalis was the most frequent pathogen, with an overall prevalence of 20% (24% in rural areas and 16% in urban areas). Other pathogenic enteroparasites were Cyclospora cayetanensis (5% in rural and urban areas), Iodamoeba butschlii, Hymenolepis spp., Trichuris trichiura and Enterobius vermicularis, with prevalence lower than 2%. In this work, G. duodenalis genotypes were molecularly characterized by a study of the glutamate dehydrogenase (gdh) and 18S rRNA genes. This is the first study of molecular characterization of G. duodenalis in Moroccan children, and the sequence analysis revealed both Assemblage A (AII) and Assemblage B (BIII, BIV), with the predominance of Assemblage BIV (73%).

    This study, a companion paper to Renou et al. (2011), focuses on the application of a GIS-based method to assess building vulnerability and damage in the event of a tsunami affecting the coastal area of Rabat and Salé, Morocco. This approach, designed within the framework of the European SCHEMA project (www.schemaproject.org) is based on the combination of hazard results from numerical modelling of the worst case tsunami scenario (inundation depth) based on the historical Lisbon earthquake of 1755 and the Portugal earthquake of 1969, together with vulnerability building types derived from Earth Observation data, field surveys and GIS data. The risk is then evaluated for this highly concentrated population area characterized by the implementation of a vast project of residential and touristic buildings within the flat area of the Bouregreg Valley separating the cities of Rabat and Salé. A GIS tool is used to derive building damage maps by crossing layers of inundation levels and building vulnerability. The inferred damage maps serve as a base for elaborating evacuation plans with appropriate rescue and relief processes and to prepare and consider appropriate measures to prevent the induced tsunami risk.

    Leishmaniases are parasitic diseases frequent in the Mediterranean Basin. Cutaneous leishmaniasis (CL) has been recently emerged in several new foci, causing a public health problem in Morocco. This study was performed to evaluate the epidemiological status of cutaneous leishmaniasis (CL) in Beni Mellal and Fquih Ben Saleh Provinces and to identify the causative agent. A total of 584 (56% female, 44% male) confirmed cases of CL were enrolled during the study period 2000-2012. Majority of cases (56%) were recorded in three sectors: Zaouiat Cheikh, Beni Mellal and Oulad Ayad. Fisher statistical test showed that there is a significant effect of the total cases of CL affected in the 185 localities. The age distribution of CL cases was relatively stable, with the majority of patients (62.34%) aged less than 9 years old with significant differences (p-value<2.2e-16). CL lesions were mostly located on the face (89%). The average number of lesions per patient was 1.38. Leishmania tropica was identified as the causative agent based on species-specific ITS1-PCR-RFLP assay.

    Integrating the control of multiple neglected zoonoses at the community-level holds great potential, but critical data is missing to inform the design and implementation of different interventions. In this paper we present an evaluation of an integrated health messaging intervention, using powerpoint presentations, for five bacterial (brucellosis and bovine tuberculosis) and dog-associated (rabies, cystic echinococcosis and leishmaniasis) zoonotic diseases in Sidi Kacem Province, northwest Morocco. Conducted by veterinary and epidemiology students between 2013 and 2014, this followed a process-based approach that encouraged sequential adaptation of images, key messages, and delivery strategies using auto-evaluation and end-user feedback. We describe the challenges and opportunities of this approach, reflecting on who was targeted, how education was conducted, and what tools and approaches were used. Our results showed that: (1) replacing words with local pictures and using "hands-on" activities improved receptivity; (2) information "overload" easily occurred when disease transmission pathways did not overlap; (3) access and receptivity at schools was greater than at the community-level; and (4) piggy-backing on high-priority diseases like rabies offered an important avenue to increase knowledge of other zoonoses. We conclude by discussing the merits of incorporating our validated education approach into the school curriculum in order to influence long-term behaviour change.

    Population growth, urbanisation and increased per capita milk consumption are main reasons for recent increasing milk demand in Africa. Due to globalisation, it is important to know how competitive various production systems are, especially as most governments promote local production and disfavour dairy imports. The TIPI-CAL (Technology Impact, Policy Impact Calculations model) was used to analyse and compare costs and returns of predominant dairy farming systems in South Africa, Morocco, Uganda and Cameroon. Results show that, as farms grew larger in size, family resources (especially land and labour) became insufficient and there was need for their acquisition from external sources. Though extensive dairy farming systems had the lowest cost of milk production (<20 US-$ per 100 kg milk), their input productivities and milk yields were lower, leading to very low net cash returns from dairying. Large intensive farms in South Africa had relatively low costs (<30 US-$ per 100 kg milk) and a high Return on Investment (ROI) due to a higher efficiency of input utilisation. It was concluded that, intensification of dairy farming and simultaneously increasing the scale of production will greatly increase productivity of farm inputs, thus recommended for development of the dairy sector in African countries.

    We describe an extensive ichnofossil assemblage from the likely Cenomanian-age 'lower' and 'upper' units of the 'Kem Kem beds' in southeastern Morocco. In the lower unit, trace fossils include narrow vertical burrows in cross-bedded sandstones and borings in dinosaur bone, with the latter identified as the insect ichnotaxon Cubiculum ornatus. In the upper unit, several horizons preserve abundant footprints from theropod dinosaurs. Sauropod and ornithischian footprints are much rarer, similar to the record for fossil bone and teeth in the Kem Kem assemblage. The upper unit also preserves a variety of invertebrate traces including Conichnus (the resting trace of a sea-anemone), Scolicia (a gastropod trace), Beaconites (a probable annelid burrow), and subvertical burrows likely created by crabs for residence and detrital feeding on a tidal flat. The ichnofossil assemblage from the Upper Cretaceous Kem Kem beds contributes evidence for a transition from predominantly terrestrial to marine deposition. Body fossil and ichnofossil records together provide a detailed view of faunal diversity and local conditions within a fluvial and deltaic depositional setting on the northwestern coast of Africa toward the end of the Cretaceous.

    Interruption in tuberculosis (TB) treatment still remains the most important challenge for control of the disease. This study aimed to identify the determinants of TB treatment default in Fez, Morocco. A 1:2 pair-matched case-control study was carried out in the TB control units in Fez. Cases were defaulters to TB treatment and were matched by age and sex to non-defaulters (controls). Of the 320 patients (108 defaulters, 212 controls), 80.6% were male. The main reason for defaulting reported by patients was the sensation of being cured. Predictive factors for treatment default in the multivariate conditional logistic regression analysis, were: relapsed case (adjusted OR = 4.49; 95% Cl: 1.87-10.8), current smoking (aOR= 2.10; 95% Cl: 1.07-4.14), alcohol use (aOR = 2.92; 95% Cl: 1.04-8.19), being more than 30 minutes away from the health centre (aOR = 3.34; 95% Cl: 1.06-10.5) and perception of having received insufficient explanation about the disease (aOR = 2.87; 95% CI: 1.53-5.36). The rate of defaulting in Fez can be lowered through targeted and realistic measures.

    Iron deficiency anaemia is an important health problem in Morocco. This study was conducted to estimate the prevalence of anaemia among school children in Kenitra. The sample represents school children of all educational levels and age ranged between 6-15 years. The level of hemoglobin, haematocrit, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration was measured in a group of 271 school children. The seric iron was assessed and anaemia was defined when hemoglobin < 11.5 g dL(-1). A questionnaire was developed to obtain information about the daily food consumption and socio-economic conditions. The prevalence of anaemia was 16.2%. The mean hemoglobin concentration was 12.53 g dL(-1) in boys and 12.52 g dL(-1) in girls. The results suggest that iron deficiency is an important determinant of anaemia in this population. There was a significant relationship between education of the mother and anaemia in children (p = 0.004) but not with the family income. It is concluded that improving the economic status of the family, women education and health education about balanced animal and plant food consumption are recommended strategies to reduce the burden of anaemia.

    We studied the contamination by organochlorine insecticides of the clams and eels in Moulay Bousselham lagoon, on the west coast of Morocco. DDT and its metabolites, DDE and DDD, were found to have accumulated in the lipids of all specimens. Organochlorine concentration in clams was highest for samples taken from the mouth of channels draining agricultural land. Organochlorine content was more than 100 ng/g in some cases in this area, whereas it was less than 40 ng/g in the rest of the lagoon. Organochlorine content peaked in May and then decreased after egg laying. Marked concentration of these pesticides was observed in eels, which are mobile and carnivorous. Organochlorine content peaked in November, mainly among the large specimens preparing to migrate to the ocean. DDT was stored in lipids, at concentrations up to 2,000 ng/g. However, even this high concentration is below the upper limit for human consumption. The higher proportion of DDE than of DDT shows that most of the contamination is not recent. BHC and cyclodienes were also detected, at low concentrations. The contamination of eels and clams in the Moulay Bouselham does not currently pose a threat to public health.

    The southwestern Middle Atlas (Morocco), which has long been regarded as a southern extension of the Tabular Middle Atlas (Ain Leuh Causse), actually consists of a broad syncline and narrow anticlinal ridges that were folded between the Liassic and Dogger epochs. Using lithostratigraphic, biostratigraphic and structural analysis, we draw the geometry of structures during the Late Liassic-Early Dogger epoch and reconstruct the various stages of their evolution. This area, which has been considered a coastal border of the tethyan atlasic trough, corresponds to a distinct basin composed of a mosaic of sub-basins tilting to the west (i.e., toward the Atlantic). These sub-basins are attributable to a double-structuring: (1) SW-NE superimposed on existing anticlinal ridges and (2) submeridian which original direction SSW-NNE seems to indicate an influence of the Atlantic coast. Tectonic segmentation preceded the Early Toarcian anoxic crisis, and tectono-eustatic interactions continued during the Late Liassic and Early Dogger epochs. Sub-basins subsequently functioned alternately as depressions in the early Late Toarcian and early- and -middle Aalenian epochs or as depocentres in the Late Toarcian and Late Aalenian epochs. Tectonics and eustasy caused a palaeobiological subdivision during the Early and Middle Aalenian epochs, as indicated by significant SE-NW segregation between ammonite faunas of Tethyan and northwestern European origin. This study indicates that the original palaeogeographic position of the southwestern Middle Atlas was at the crossroads of the Tethyan and Atlantic margins.

    Microbiological analysis of 1025 marine samples, including 345 from seawater, 337 from shellfish, and 343 from sediments collected between January 2000 and December 2002 from 18 shellfish sites on the Atlantic coast of mid-west of Morocco (Agadir region), yielded 143 strains of Listeria (Listeria monocytogenes: 38; L. innocua: 109; L. ivanovii: 1). The overall incidence of Listeria sp. in the coastal environment was 5.3%. Thirteen L. monocytogenes strains were isolated from seawater, 7 from sediment, and 12 from shellfish. The 38 strains of L. monocytogenes were phenotypically characterized. All belonged to two chemotypes according to appareillage et procédé d'identification (API) Listeria classification: 8 strains were type 2510, alpha-mannosidase-negative and hemolytic; and 30 strains were type 6510, alpha-mannosidase-positive, of which 8 strains were nonhemolytic. All the L. monocytogenes strains belonged to the 1/2 serogroup, with serovar 1/2b clearly prevalent (78.9%), although some nonhemolytic strains were serovar 1/2a. This collection of L. monocytogenes strains included 6 different pulsotypes as assessed by DNA macrorestriction with the restriction enzymes AscI and ApaI.

    The aim of this work was using the legume plant Anthyllis vulneraria L. (ecotype metallicolous) as a trap plant, in order to isolate metal-tolerant rhizobial strains from metal-contaminated soils from Morocco, with pollution indexes spanning three orders of magnitude. As bioindicator, soil bacterial density was inversely correlated to the pollution index. Forty-three bulk soil bacteria and sixty two bacteria from nodules were isolated. The resistance of bacteria from nodules to heavy metals was four to ten times higher than that of bulk soil bacteria, reaching high maximum tolerable concentrations for Cd (2 mM), Cu (2 mM), Pb (7 mM), and Zn (3 mM). Besides, some strains show multiple metal-tolerant abilities and great metal biosorption onto the bacterial surface. Amplification and restriction analysis of ribosomal 16S rDNA (ARDRA) and 16S ribosomal DNA (rDNA) sequencing were used to assess biodiversity and phylogenetic position among bacteria present in nodules. Our results suggest that a great diversity of non-rhizobial bacteria (alpha- and gamma-proteobacteria) colonize nodules of Anthyllis plants in contaminated soils. Taking together, our results evidence that, in polluted soils, rhizobia can be displaced by non-rhizobial (and hence, non-fixing) strains from nodules. Thus, the selection of metal-resistant rhizobia is a key step for using A. vulneraria symbioses for in situ phytoremediation.

    Sera from 221 cattle were collected in 25 farms in Morocco to investigate the evidence and circulation of some of the main bovine abortive agents in the dairy cattle farming, where abortions are often reported. All sera were examined for brucellosis, 176 for neosporosis, 88 for leptospirosis, and 42 for Bovine viral diarrhoea (BVD/MD), Bovine Herpesvirus 1 (BHV-1) (Infectious bovine rhinotracheitis, IBR/IPV), and Bovine Herpesvirus 4 (BHV-4) infections (at least 1 sample per herd). Abortions were reported in 23 (10.4%) of the 221 tested cattle. Antibodies against the investigated pathogens were detected in all samples tested, with an overall seroprevalence of 33.48% for Brucella, 9.09% for Leptospira, 8.52% for Neospora, 37.71% for BVDV, 50% for BHV-1, 9.52% for BHV-4. As for Leptospira antibodies against serovars Hardjo, Pomona, and Tarassovi were identified. Mixed infections were common. The lack of evidence of non-infectious factors epidemiologically related to abortions suggested that the investigated agents are to be considered important risk factors in the dynamic of the abortion syndrome, even if further investigations are necessary to identify the abortion cause. Particular attention should be paid on brucellosis, considering the high seroprevalence and its zoonotic relevance.

    Numerous studies on the impact of anthropogenic activities on coastal water quality have been carried out in the last three decades, focusing mainly on urban expansion and agricultural development in coastal areas. In this study, we assess heavy metal pollution in the superficial and cored sediment of the Oualidia lagoon (Morocco). Superficial and cored sediment samples from the Oualidia lagoon were analyzed for Al, Fe, Cu, Zn, Pb, Mn, Ni, Cr, Hg and Cd using ICP-MS. Sediments near urban and agricultural areas are commonly contaminated with heavy metals and the concentrations found in surface sediments are significantly higher than those from 50-100 years ago. The concentrations of these elements decrease sharply with depth in the sediment column and the elements are preferentially enriched in the <2 µm-size fraction of the sediment. The enrichment factors (EF) and statistical analyses, demonstrated that heavy metals that might pose a risk (Pb, Cu and Hg) have become largely enriched in the lagoon sediments during the recent period of agricultural intensification. Ni and Cr are the main pollutants originating from urban sewage. Keywords: Coastal land use, heavy metals, sediment pollution, lagoon.

  18. Famine relief and imperial policy in early modern Morocco: the political functions of public health.

    There has been no systematic ethnology nor comparative history of public health. In fact, there has been a broad consensus that prior to the arrival of missionaries and colonial health authorities there was no indigenous public health. These assumptions apply to only some settings and do not reflect the general history of public health. The present study concerns public health in the first century of Alawi rule in Morocco, ca. 1670-1790. The early Alawi sultans undertook public health programs, most of which concerned the prevention and relief of mass starvation. Goals of the programs were consistent with other features of their public policies. Effectiveness of the programs was limited partly by technical and scientific factors, but more by political constraints, especially the sultans' higher priorities for political stability than public welfare and public health. These data provide important insights not only into Moroccan social and political history, but also into the more general problem of the political nature of public health.

    Background New tetradactyl theropod footprints from Upper Jurassic (Oxfordian-Kimmeridgian) have been found in the Iouaridène syncline (Morocco). The tracksites are at several layers in the intermediate lacustrine unit of Iouaridène Formation. The footprints were named informally in previous works “Eutynichnium atlasipodus”. We consider as nomen nudum. Methodology/Principal Findings Boutakioutichnium atlasicus ichnogen. et ichnosp. nov. is mainly characterized by the hallux impression. It is long, strong, directed medially or forward, with two digital pads and with the proximal part of the first pad in lateral position. More than 100 footprints in 15 trackways have been studied with these features. The footprints are large, 38–48 cm in length, and 26–31 cm in width. Conclusions/Significance Boutakioutichnium mainly differs from other ichnotaxa with hallux impression in lacking metatarsal marks and in not being a very deep footprint. The distinct morphology of the hallux of the Boutakioutichnium trackmaker –i.e. size and hallux position- are unique in the dinosaur autopodial record to date. PMID:22180775

    1994-07-01

    The Rharb basin in Morocco is a Tertiary foreland filled by clastic series during the Miocene and Pliocene. This terrigenous influx, derived from the prerif to the northeast and the Meseta to the south, is characterized by a sandy episode during much of the Messinian and the Tortonian. The sand deposits were probably related to the uplift and major erosion of a part of the prerif during the sliding of an olistostrome (prerif nappe). Although most of the wells drilled in the basin have encountered biogenic gas accumulations, the problem still facing exploration in the area is seismic resolution and thin-bed tuning analysis. Recent studies using high seismic resolution techniques have permitted the authors to gain a deep insight into the stratigraphy and depositional environment of the thin sand reservoirs and their fluid content. AVO stratigraphy, inversion of seismic traces into acoustic impedance traces and seismic attributes calculation, and computing provide a remarkable example of the possibilities of depicting the lateral and vertical evolution of reservoir facies and localizing biogenic gas accumulations. Out of five recent exploratory wells drilled based on this new technique, three encountered gas-bearing sands with economic potential. Fifty-three amplitude anomalies have been identified and await processing.

  1. Contribution of structural geology to assessment of hydrocarbon play in Casablanca Offshore, Morocco

    The Casablanca offshore area, is located in the northwestern part of the Meseta structural domain of Morocco. The Moroccan meseta consists of two major zones, separated by a shearing and overthrusting zone. The eastern zone, contains outcroping massifs that are characterized by Hercynian granitic intrusives and Cambrian to Carboniferous rocks that were strongly folded and faulted during the Hercynian event. The Casablanca offshore area is presently covered by good quality and recently acquired, seismic, gravity and magnetic data. The previous petroleum exploration studies carried out in Casablanca offshore, worked out different structural models based on seismic interpretation, but these models do not agree exactly neither with the gravity and magnetic data nor with the regional structural framework. However, recent study of several structural features, outcropping immediately to the East of the study area, resulted in the elaboration of new structural transects that were used as model for the achievement of new and more accurate seismic interpretation. The Paleozoic rocks were also studied for their hydrocarbon potential as source rocks, reservoir rocks and seals. These new concepts summarize the great petroleum exploration interest in this area and may provide giant discoveries of oil and/or gas fields.

    West Nile disease (WND) is one of the most widespread mosquito-borne infectious diseases in the World. In Morocco the first WND cases were reported in equines in 1996. After an apparent epidemiological silence, WND re-occurred in 2003 and in 2010, when the disease was reported in equines living in the central and north-western part of the country. Eco-climatic variables are known to influence the mosquito presence and abundance and, therefore, the probability of occurrence of mosquito-borne infections. The remote sensed values of Land Surface Temperature (LST), Normalised Difference Vegetation Index (NDVI) and rainfall registered from 2001 to 2010 were evaluated for a possible association with the occurrence of WND cases in 2003 and in 2010. In the zones where WND cases occurred, NDVI values recorded in 2003 and 2010, from June to November, were significantly higher than those registered during the same months in the rest of the decade. Rainfall data showed higher peaks in 2003 and 2010, when the number of days with extreme rainfall was significantly higher during 1-2 months before the occurrence of WND cases. Temperature does not seem to play an important role in Moroccan epidemiological conditions.

    Feeding wildlife is a very popular tourist activity, largely because it facilitates the close observation of animals in their natural habitat. Such provisioning may benefit animals by improving their survival and reproductive success, especially during periods of natural food shortage. However, provisioning by tourists may also have negative impacts on the health of the animals involved; to date such impacts are poorly understood. Here, we investigated the effects of tourist provisioning on the health of wild adult Barbary macaques, Macaca sylvanus, in Morocco. We compared health measures between a heavily provisioned group and a group that received negligible food from tourists and, in the former group, we also assessed health measures in relation to the intensity of provisioning. We used a broad range of non-invasive health measures relating to birth rate and survival, disease and injury risk, body size and condition, and physiological stress. Our findings indicate that feeding by tourists may overall have negative impacts on the health of Barbary macaques, being linked in particular to larger body size, elevated stress levels and more alopecia. Finally, we propose a framework to help consider the potential costs and benefits of provisioning, which may facilitate future research and management decisions on whether—and how much—provisioning is acceptable.

The detected residue levels ranged from 0.001 to 0.400 mg kg(-1) for dicofol, from 0.003 to 0.170 mg kg(-1) for procymidone, from 0.001 to 0.250 mg kg(-1) for chlorothalonil, from 0.050 to 0.500 mg kg(-1) for bifenthrin, from 0.001 to 0.010 mg kg(-1) for λ-cyhalothrin, from 0.001 to 0.300 mg kg(-1) for cypermethrin, from 0.010 to 1 mg kg(-1) for deltamethrin and from 0.003 to 1.123 mg kg(-1) for endosulfan. European MRL for endosulfan in tomatoes set in 0.500 mg kg(-1), was exceeded in 8 samples, and MRL for deltamethrin set in 0.300 mg kg(-1) for tomatoes was exceeded in 2 samples.

  5. Argan woodlands in South Morocco as an area of conflict between degradation and sustainable land use

    The Argan woodlands are endemic for South Morocco and prone to degradation through expanding and intensifying agriculture and overgrazing. Unvegetated areas extend further due to degradation of soil and vegetation. Here infiltration is less than on vegetated areas, while runoff and soil erosion increase. The sale of the highly valuable oil, gained from the seeds of the argan tree, can be seen as an economic alternative for the region and a chance of survival for the argan woodlands. With the introduction of women's cooperatives for the production and sale of the oil, the Gesellschaft für Technische Zusammenarbeit (GTZ, Association for Technical Cooperation) hoped to halt argan degradation from 1995 to 2002. The effects of this approach shall be studied in a proposed DFG-project. The erosion gradient between soils under canopy cover and intertree areas in varying stages of degradation will be at the center of the analysis. Insight into onsite and offsite degradation shall be gained through the measurement of runoff and erosion rates, which lead to rill and gully erosion downslope. Measurements of soil chemical and physical properties might also help indicate when an argan woodland can be classified as natural. Furthermore to be studied are the effects of the new found value of the Argan woodlands among the local population with focus on regional tourism and a possible reduction of grazing pressure. Sustainable soil management in combination with the needs of the local population is essential for a sustainable land use in the region.

    A serological survey was conducted to estimate the seroprevalence of 5 major abortive infections in 13 sheep flocks and 10 goat herds in 2 regions of Morocco. A total of 308 from aborted females (202 ewes and 106 does) and 197 sera (97 ewes and 99 does), were tested for brucellosis, chlamydiosis, Q fever, toxoplasmosis, and for 9 major serovars of Leptospira. An average abortion rate of 12.10% was found in ewes and 10.26% in does. The serological analyses revealed the presence of all 5 abortive infections, both in sheep and in goats. Ten (43%) herds/flocks were positive to brucellosis, 21 (91%) to chlamydiosis, 17 (74%) to toxoplasmosis, 13 (57%) to Q fever, and 5 (22%) to leptospirosis. Leptospira spp. serovars Copenhageni and Grypothyphosa were found in a single sheep flock, while Tarassovi and Copenhageni were detected in 4 goat herds. Of the 23 investigated herds/flocks, 22 (96%) showed mixed infections. The findings of this study confirmed the possible involvement of the 5 selected abortive infections in abortion outbreaks occurring in the investigated regions. Further investigations are needed to better understand the aetiology of infectious abortions in herds and flocks within investigated regions.

    Dust devils are vertical convective vortices occurring on Earth and Mars [1]. Entrained particle sizes such as dust and sand lifted by dust devils make them visible [1]. On Earth, finer particles (<~50 μm) can be entrained in the boundary layer and transported over long distances [e.g., 2]. The lifetime of entrained particles in the atmosphere depends on their size, where smaller particles maintain longer into the atmosphere [3]. Mineral aerosols such as desert dust are important for human health, weather, climate, and biogeochemistry [4]. The entrainment of dust particles by dust devil and its vertical grain size distribution is not well constrained. In situ grain size samples from active dust devils were so far derived by [5,6,7] in three different continents: Africa, Australia, and North America, respectively. In this study we report about in situ samples directly derived from active dust devils in the Sahara Desert (Erg Chegaga) in southern Morocco in 2012 to characterize the vertical grain size distribution within dust devils.

    Complete, articulated crinoids from the Ordovician peri-Gondwanan margin are rare. Here, we describe a new species, Iocrinus africanus sp. nov., from the Darriwilian-age Taddrist Formation of Morocco. The anatomy of this species was studied using a combination of traditional palaeontological methods and non-destructive X-ray micro-tomography (micro-CT). This revealed critical features of the column, distal arms, and aboral cup, which were hidden in the surrounding rock and would have been inaccessible without the application of micro-CT. Iocrinus africanus sp. nov. is characterized by the presence of seven to thirteen tertibrachials, three in-line bifurcations per ray, and an anal sac that is predominantly unplated or very lightly plated. Iocrinus is a common genus in North America (Laurentia) and has also been reported from the United Kingdom (Avalonia) and Oman (middle east Gondwana). Together with Merocrinus, it represents one of the few geographically widespread crinoids during the Ordovician and serves to demonstrate that faunal exchanges between Laurentia and Gondwana occurred at this time. This study highlights the advantages of using both conventional and cutting-edge techniques (such as micro-CT) to describe the morphology of new fossil specimens. PMID:26664800

    The general geology of the peraluminous rocks of the Bou-Azzer region (Central Anti-Atlas, Morocco) and their firing transformations were investigated by several techniques: optical microscopy, microprobe analysis, X-ray diffraction (XRD), X-ray fluorescence (XRF), thermal analysis, scanning electron microscope (SEM), energy dispersive spectrometry (EDS), and by measuring selected physical properties. The results of the geological study show that these rocks consist mainly of a quartz-pyrophyllite assemblage (70-74 wt.% SiO 2 and 14-17 wt.% Al 2O 3), associated with minor amounts of muscovite and nacrite. They formed from a progressive deformation and hydrothermal alteration of felsic volcanic rocks. The principal mineralogical transformations recorded from rhyodacite to peraluminuous rocks are: K-feldspar → muscovite → pyrophyllite. Regarding the firing transformations, it is found that up to about 1100 °C the rock samples are subjected to expansion associated with the destruction of the pyrophyllite hydroxyl framework. The estimated amount of energy associated with this process is 50.226 kJ/mol. Beyond 1100 °C, a marked shrinkage was observed, due to the formation of a glassy phase, and the precipitation of mullite, cristobalite and K-feldspar. The reaction pathways for these phases are proposed and the evolved heat is determined (-160.928 kJ/mol).

    Objective. In the present study, we aimed to investigate epidemiological, clinical, and etiological characteristics of acute upper gastro-intestinal bleeding. Materials and Methods. This retrospective study was conducted between January 2003 and December 2008. It concerned all cases of acute upper gastroduodenal bleeding benefited from an urgent gastro-intestinal endoscopy in our department in Morocco. Characteristics of patients were evaluated in terms of age, gender, medical history, presenting symptoms, results of rectal and clinical examinations, and endoscopy findings. Results. 1389 cases were registered. As 66% of the patients were male, 34% were female. Mean age was 49. 12% of patients had a history of previous hemorrhage, and 26% had a history of NSAID and aspirin use. Endoscopy was performed in 96%. The gastroduodenal ulcer was the main etiology in 38%, followed by gastritis and duodenitis in 32.5%. Conclusion. AUGIB is still a frequent pathology, threatening patients' life. NSAID and aspirin are still the major risk factors. Their impact due to peptic ulcer remains stable in our country. PMID:21991509

    Objectives To determine the distribution of cervical high-risk human papillomavirus genotypes and their association to cellular abnormalities in women from Fez and its neighborhood. Methods Women attending the Hassan II University Hospital for cervical pap smears were recruited after an informed consent. Interviews and two cervical samples were performed for each woman. Cervical samples were used for cytological analysis and HPV DNA detection. HPV was typed using a method based on multiplex PCR with fluorescently labeled specific primers followed by capillary electrophoresis. The study was approved by the ethics committee of the Faculty of Medicine and Pharmacy of Fez. Results The HPV prevalence in the studied population was 43.1% and the most prevalent types were HPV 53 (23 cases); HPV 16 (20 cases); HPV 35 (18 cases); HPV 51 (10 cases) and HPV 56 (7 cases). From the 619 confirmed pap smears, 20% were abnormal. The cytological abnormalities were significantly associated to HPV infection, women age, number of pregnancies and parity (p < 0.05). Conclusion More attention should be given to HPV in Morocco because it represents an important public health concern. The distribution of carcinogenic HPV types in the studied population is different from the data in other regions but epidemiological studies in other Moroccan regions are required. PMID:26731415

    Anaplasma phagocytophilum is an emerging tick-borne zoonosis with extensive increased interest. Epidemiological data are available in several regions of the USA, Europe and Asia in contrast to other parts of the world such as North Africa. Blood samples of 261 healthy individuals divided in two groups i.e., dog handlers and blood donors were analysed. Indirect immunofluorescent assay using a commercial kit was performed to detect specific A. phagocytophilum IgG. Two dilutions were used to assess the prevalence of seroreactive samples. Demographic variables were assessed as potential risk factors using exact logistic regression. Seropositivity rates reached 37% and 27% in dog handlers and 36% and 22% in blood donors. No statistically significant differences were found in the prevalence rates between the two groups. Analysis of risk factors such as gender, age groups, outdoor activities, self-reported previous exposure to ticks, or contact with domestic animals (dogs, cats, ruminants and horses) did not shown any significant difference. A. phagocytophilum exposure was common in both high-risk population and blood donors in Morocco. PMID:27532208

    Four imbricated mafic to felsic plutons of Variscan age from Morocco have been investigated for their cooling history and geochemical interactions with surrounding continental rocks. Oxygen isotope compositions of whole rocks and minerals have been used to model the cooling rates of these kilometer-sized intrusions. By combining both the knowledge of oxygen-self diffusion data of rock-forming minerals and the determination by IR-spectroscopy of the water content of quartz, the cooling times are estimated ranging from 105 to 5 × 105 years in agreement with the shallow emplacement (4-6 km depth) of these intrusions into the continental crust. Such fast cooling rates could explain why after assimilation of the various country rocks, heterogeneities of both neodymium and strontium isotope ratios were still preserved. A progressive δ18O increase from the mafic to felsic terms of the plutonic suite, which does not excess 1 to 1.5‰, could be explained by the assimilation of metamorphosed pelitic and volcanic rocks that constitute the basement of the Tichka plutonic complex.

    Characterization of the petroleum potential for the Atlantic margin of Morocco has been based primarily on limited, antiently acquired organic geochemical data. These indicate the area of drilling behind the paleoshelf edge to be only fair in organic carbon and C15+ extract values with predominantly terrestrial kerogen types. Recently acquired geochemical data obtained from relatively recent drilling both behind and beyond the paleoshelf edge indicate 4 depositional facies containing hydrogen rich amorphous kerogen assemblages. These are: (1) Lower to Mid Jurassic inner shelf facies probably deposited in algal rich lagoon-like, (2) Lower Cretaceous non marine coaly facies probably deposited in algal rich swamplike environments, (3) Middle Cretaceous facies characterized by restrited anoxic environment with sediments rich in marine kerogen types deposited under sluggish wather circulation, (4) Upper Cretaceous to Tertiary outer-shelf to Upper slope facies probably deposited under algal-rich upwelling systems. Of these, the Cretaceous facies is the most widespread and represents the best source rock potential characteristics. Correlation of these facies to recently acquired good quality seismic packages allows for extrapolation of probable organic facies distribution throughout the continental margin. This should enhance the hydrocarbon potential of the Mesozoic and Cenozoic sediments both landward and seaward of the paleoshelf edge and thus permits refinement of strategies for hydrocarbon exploration in the area.

    The rising demand for water and the contamination of shallow water table aquifers has led authorities in NE Morocco to look for deeper groundwater resources in the Triffa Plain, namely in Lower Jurassic (Lias) dolomitic limestones. The liassic aquifer is of strategic importance for the development of the region, however, its hydrodynamic behaviour is poorly understood due to lack of hydrogeological data and block structure. This article presents a first effort towards understanding the structure and hydraulic behaviour of the aquifer. Exploration borehole data and results from geophysical campaigns were integrated into a GIS environment to build a preliminary model of the aquifer structure. The aquifer behaves as an unconfined aquifer in the northern part of the Béni Snassen Mountains (the recharge area), but as it dips to the north, it becomes confined by marls and shales of the Middle/Upper Jurassic. Even though piezometric level data are scarce, a tentative piezometric map was produced. Three blocks separated by NW-SE trending faults in a horst and graben structure, with distinct flow behaviours were identified: Berkane, Fezouane and Sidi Rahmoun blocks. Those blocks also show differences in hydraulic conductivity distribution. As a result of the reaction with the dolomitic limestones, the groundwater is of calcium-magnesium bicarbonate type. Groundwater temperature as measured in springs ranges from 29 °C to 37 °C in springs and constitutes a potential low enthalpy geothermal resource.

    Salmonella is among the most important food borne pathogens worldwide contaminating a wide range of animal products including meat products. The aims of this study go through two steps: The first step is to estimate the proportion of sausages products contaminated with Salmonella in Meknes city (Morocco), which were collected from various shopping sites: butchery, street vendors, supermarket and souk (Weekly market combines the population of the small villages around Meknes city). The second one is to identify serovars, to determine the antimicrobials resistance patterns of isolates and to detect the invA and spvC genes. 34 (21.79%) Salmonella were isolated, recovered 4 serogroups and 12 serotypes. The most prevalent serotypes were Salmonella Corvallis (23.53%) and Salmonella Kentucky (17.65%). All Salmonella isolates were tested for their susceptibility to 18 selected antimicrobials agents, of which 100% were resistant to at least one antimicrobial, 85.30% (29/34) were resistant to two or more antimicrobials and 44.12% (15/34) were resistant to at least three antimicrobials. All Salmonella are resistant to ampicillin, 76.47% to streptomycin, 20.59% to sulfonamides, 17.65% to Tetracycline and 11.77% to Ofloxacin. The "ACSSuT" penta-resistance pattern was observed in tow of the Salmonella Typhimurium strains. In addition, this study showed that all Salmonella strains (34) were positive for invasion gene invA and negative for the virulence gene spvC.

    This study was undertaken to determine the possible health risk associated with raw wastewater use in agricultural purposes, particularly, the transmission of parasite infections among children of five regions in Beni-Mellal, Morocco. In a randomly-selected sample of 1343 children, 740 of them were from five regions using raw wastewater for agriculture, and 603 were from 4 control regions that do not practice wastewater irrigation. One or more parasite infections were identified in 50.8% of the children living in the wastewater re-use regions and in 8.2% only of the others. The seven parasites identified were Entamoeba histolytica, Giardia intestinalis, Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis, Hymenolepis nana, Taenia saginata, which infected 34.3%, 5.1%, 20.5%, 0.4%, 5.2%, 7.2%, 0.5% in the exposed population and 4.3%, 0.3%, 3.8%, 0.3%, 1.0%, 0.6% and 0.0% in the control population respectively. In conclusion, raw wastewater use in Beni-Mellal lead to a high risk of parasite infections. Adequate treatment of wastewater is highly recommended.

    Air temperature is considered to be an essential variable for the study and analysis of meteorological regimes and chronics. However, the implementation of a daily monitoring of this variable is very difficult to achieve. It requires sufficient of measurements stations density, meteorological parks and favourable logistics. The present work aims to establish relationship between day and night land surface temperatures from MODIS data and the daily measurements of air temperature acquired between [2011-20112] and provided by the Department of National Meteorology [DMN] of Casablanca, Morocco. The results of the statistical analysis show significant interdependence during night observations with correlation coefficient of R2=0.921 and Root Mean Square Error RMSE=1.503 for Tmin while the physical magnitude estimated from daytime MODIS observation shows a relatively coarse error with R2=0.775 and RMSE=2.037 for Tmax. A method based on Gaussian process regression was applied to compute the spatial distribution of air temperature from MODIS throughout the city of Casablanca.

    The cork oak forest of Ma'amora in north-western Morocco was the largest cork oak forest in the world until the beginning of the 20th century. Due to growing land use for agriculture and urbanization, however, this forest has become fragmented into relatively small and isolated patches. The effects of this fragmentation on the diversity of wild animal communities have never been investigated despite the importance of such investigations in elaborating long-term conservation plans of the biodiversity of this forest system. In this study of a sample of 44 forest patches we assessed the relationships between species numbers of wintering, breeding and spring migrant birds and patch size, shape, isolation and vegetation structure. We found that species richnesses of the three studied bird assemblages were strongly related to local vegetation structure, namely to the diversity and abundance of trees and bushes. Patches with higher diversity and cover of trees and bushes support higher numbers of bird species. However, patch size, shape and isolation were not significant predictors of bird richness. These results suggest that bird communities in the studied forest patches were more likely shaped by local habitat suitability rather than the amount of habitat or patch isolation. The results also demonstrate negative effects of current human pressures, namely logging, grazing and disturbance, on the diversity of bird communities in this forest system. This emphasizes the need for urgent management efforts aiming at reducing the negative impacts of forest use by humans on bird diversity in this forest system.

  20. Longitudinal to transverse drainage network evolution in the High Atlas (Morocco): The role of tectonics

    The High Atlas of Morocco is a still-active, linear intracontinental mountain chain in the NW African plate, which results from weak crustal thickening associated with rift inversion during the Cenozoic and from uplift related to mantle thermal doming. A striking morphological feature of the High Atlas is the occurrence of both transverse and longitudinal (i.e., strike-parallel) drainage characterized by deep fluvial incision of more than 1000 m in low-relief topography of the axial zone of the chain. Most of the transverse component of the drainage appears to postdate the longitudinal component as indicated by recent or incipient captures and wind gaps. The longitudinal drainage is inherited from an early stage of fluvial organization controlled by the tectonic structures developed during upper crustal folding and thrusting in the post-Paleozoic cover. Amplification of N-S regional slope in the western High Atlas by continued crustal shortening and thickening triggered: (i) higher erosion rates in transverse than in longitudinal catchments and (ii) captures of longitudinal streams by transverse ones, creating a new organization of the drainage system toward the regional slope. Such evolution from a longitudinal to a transverse-dominated drainage may represent a common mechanism of fluvial network development in mountain belts where the amplification of the regional slope results from long-lived lithospheric convergence.

    The High Atlas of Morocco is a linear intracontinental mountain chain in the NW African plate. The Atlas mountain system results from weak crustal thickening associated with rift inversion during Cenozoic times and from uplift related to lithospheric-scale thermal doming, approximately parallel to the trend of the chain. A striking morphological feature of the High Atlas is the occurrence of both transverse and longitudinal drainage characterized by deep fluvial incision of more than 1000 m in low-relief topography of the axial zone of the chain. Most of the transverse component of the drainage appears to postdate the longitudinal component as indicated by recent or incipient captures and wind gaps. The longitudinal drainage is inherited from an early stage (Paleogene to Miocene in age) of fluvial organization controlled by the tectonic structures developed during upper crustal folding and thrusting in the post-Paleozoic cover. Post-Miocene, amplification of N-S regional slope in the western High Atlas by crustal shortening and thickening triggered: (i) higher erosion rates in transverse than in longitudinal catchments and (ii) captures of longitudinal streams by transverse ones creating a new organization of the drainage system toward the regional slope. Such evolution from a longitudinal to a transverse-dominated drainage may represent a common mechanism of fluvial network development in mountain belts where the amplification of the regional slope results from long-lived lithospheric convergence.

    The study is an environmental isotope investigation of groundwater samples from the Turonian Aquifer of Tadla Basin in Morocco for the purpose to confirm that this aquifer could be a potential site for palaeoclimate reconstruction. The collected groundwater samples were examined for δ18O, δ2H, δ13C, noble gas concentrations, radiocarbon and tritium. Radiocarbon ages obtained from different isotope geochemical models indicates that the recharge of all these water samples occurred during the Holocene, we obtained a palaeotemperature record for the last 10 kyr. The calculated noble gas solubility temperatures of the confined part of the aquifer are varying around the recent mean annual soil temperature of 19 °C. However the noble gas temperatures of the unconfined part of the aquifer are a few degree C higher than expected. The obtained noble gas and tritium values might be stated this hypothesis as well. Based on these data, we conclude that the Turonian aquifer might be a potential place for Late-Pleistocene palaeoclimate reconstruction if the research area would be extended in the direct of flow-path towards the western part of the basin and towards the foothill of the Phosphates Plateau.

    In Middle East and North Africa (MENA) countries, renewable groundwater and surface water supply are limited while demand for water is growing rapidly. Climate change is expected to increase water demand even further. The main aim of this paper is to evaluate the water supply-demand imbalances in Iran, Morocco and Saudi Arabia in 2040-2050 under dry, average and wet climate change projections and to show on the basis of the marginal cost and marginal value of water the optimum mix of supply-side and demand-side adjustments to address the imbalance. A hydrological model has been used to estimate the water supply-demand imbalance. Water supply and demand curves have been used to explore for which (marginal value of) water usage the marginal cost of supply-enhancement becomes too expensive. The results indicate that in the future in all cases, except in Iran under the wet climate projection, the quantity of water demanded has to be reduced considerably to address the imbalance, which is indeed what is currently happening already.

    We describe an extensive ichnofossil assemblage from the likely Cenomanian-age ‘lower’ and ‘upper’ units of the ‘Kem Kem beds’ in southeastern Morocco. In the lower unit, trace fossils include narrow vertical burrows in cross-bedded sandstones and borings in dinosaur bone, with the latter identified as the insect ichnotaxon Cubiculum ornatus. In the upper unit, several horizons preserve abundant footprints from theropod dinosaurs. Sauropod and ornithischian footprints are much rarer, similar to the record for fossil bone and teeth in the Kem Kem assemblage. The upper unit also preserves a variety of invertebrate traces including Conichnus (the resting trace of a sea-anemone), Scolicia (a gastropod trace), Beaconites (a probable annelid burrow), and subvertical burrows likely created by crabs for residence and detrital feeding on a tidal flat. The ichnofossil assemblage from the Upper Cretaceous Kem Kem beds contributes evidence for a transition from predominantly terrestrial to marine deposition. Body fossil and ichnofossil records together provide a detailed view of faunal diversity and local conditions within a fluvial and deltaic depositional setting on the northwestern coast of Africa toward the end of the Cretaceous.

    Volubilis is the most excavated and the best preserved archaeological site of Morocco. Located about thirty kilometres north of Meknes, it was a Mauritanian capital founded in the 3rd century B.C., and became an important outpost of the Roman Empire. Volubilis monuments are constructed with five regional lithotypes of limestone. A grey massive limestone and beige-yellowish calcarenite limestone are the two most largely used on Volubilis site, representing respectively about 30% and 60 % of the total volume of building stones. Field observations showed that the calcarenite limestone is more decayed than the massive limestone and is mainly affected by scaling, alveolization and sanding. This work aims to estimate the role of environmental conditions on the decay of the calcarenite stone through the effect of thermal stresses and freezing-thawing action. Air temperature data of Meknes station is analysed. Furthermore, mineralogical composition of the calcarenite limestone and its intrinsic properties required for stress calculation are determined. The results of this study show that the calcarenite limestone is a quite soft carbonate stone, contains about 71 % of calcite, 18 % of quartz and others accessory minerals. Besides, there is no risk of damage due to freezing-thawing processes. Nonetheless, thermal stresses may have an important role in the decay of calcarenite stones of the Volubilis site.

  6. Late Triassic to middle Jurassic history of the north-central high Atlas, Morocco

    The Lower and Middle Jurassic (Liassic and Dogger) rocks in the north-central High Atlas and on the adjacent Oran Meseta, Morocco, were deposited on the subsiding margin of the Triassic/Jurassic High Atlas trough. This and the Middle Atlas trough formed as a result of rifting of the Moroccan Meseta and oran Meseta from the Saharan craton during initial stages of the opening of the modern Atlantic. The Tethys seaway flooded these troughs in the early Liassic, resulting in deposition of several thousand meters of liassic and Dogger limestone and marlstone. The deepening-upward Liassic section in the north-central High Atlas reflects the rapid development of the short-lived High Atlas trough, which formed in the Late Triassic-Early Liassic flooding by the Tethys established carbonate tidal flats on the Oran Meseta, a shelf margin at the basin's edge, and slope and basin-floor deposition within the trough. Rapid subsidence of the margin brought slope and basin floor sediments on top of the platform margin as the trough developed. Subsidence slowed toward the end of the Lias, resulting in progradation of the shelf-margin environments. At the end of the Lias, a portion of the margin slid into the basin, followed by debris shed off the slide scar. Continued marlstone and limestone deposition filled the basin during the Dogger, marking the end of rift-related sedimentation in the High Atlas trough.

    The old ochre-pyrrhotite mine of Kettara, near Marrakech (Morocco) ceased operating some 30 years ago but its excavations, plants, and tailings have been totally abandoned since then. Geochemical analyses of the soils, stream sediments and waters of the surrounding area were carried out to assess the pollution impact of this mining site. Tailing characterization showed the presence of sulphide primary minerals, as well as secondary ones containing among others (Fe, S, Cu, Pb, Zn, Cd, Ni, Cr, Co, As, Se). In spite of the presence of theses pollutants in the Acid Mine Drainage (AMD) of Kettara, groundwater did not show significant levels of these metals probably related to the low ion circulation under the local dry climate with low annual rainfall that prevents metal ion circulation. The chemical analyses of soil and stream sediment samples included elements most of which are internationally considered as dangerous for human health (As, Cd, Co, Cr, Cu, Fe, Ni, Pb, S, Se and Zn). Geochemical maps of these elements showed that Cr and Ni were linked to mafic intrusions of Kettara sector. Sulphur is linked to the mining activity and the others are related both to lithological outcrops and mining activity. However, the levels of these contaminants did not exceed Italian Standards of soil pollution.

  8. Detailed mineralogy and petrology of manganese oxyhydroxide deposits of the Imini district (Morocco)

    Manganese ore in the Cenomanian-Turonian dolostone of the Imini district (south of the High Atlas, Morocco) displays a high Mn content due to the occurrence of pyrolusite, cryptomelane, hollandite sensu stricto, coronadite, romanechite, and lithiophorite. The orebodies occur mainly as three stratabound layers along the ~25-km-long ore belt following a WSW-ENE direction. Using scanning electron microscopy (SEM-EDS) coupled with X-ray diffraction (XRD), we here refine the mineralogy and petrology of Mn oxides and oxyhydroxides in order to constrain the paragenetic sequence and define the main processes of ore formation. Deposition and concentration of Mn oxyhydroxides follow a two-step sequence after dolomitization: (1) replacement of dolomite fabric (dolomite micrite and dolomite rhombs) by hollandite group minerals leading to a textural conservation and then (2) neoformation of collomorphous aggregates in an opened and brecciated system. These observations are consistent with a multistage evolution including multiple reworking and brecciation. Pyrolusite is the main Mn oxide observed in the Imini district during both early and late stages. The superficial environment provides supergene conditions suitable for the deposition of only Mn oxyhydroxides. This supergene environment and the occurrence of multiple bands of hollandite group minerals indicate an external migration (allochthonous supply) of Mn and associated elements, contemporaneous to an in situ chemical and mechanical dissolution of the host dolostone. The lithological heterogeneities of dolostone and its chemical environment compared to less permeable surrounding rocks may have provided the conditions to concentrate Mn oxides and oxyhydroxides.

    2007-05-01

    The biologic origin of objects with microbe-like morphologies from the oldest preserved terrestrial sedimentary rocks remains a matter of controversy. Their biogenicity has been questioned, as well as the claim that they are convincing evidence of early life. Though minerals with microbe-like morphologies represent ambiguous evidence of life, they are, in a number of conditions, the only achievable information. In this study, the focused ion beam (FIB) electron microscopy technique was used for nano and micrometer-scale high-resolution imaging and in situ microsectioning of filamentous microfossils. The structural elements of these filaments, their spatial relationships with the host rock, and artifacts produced by alteration of the original morphology due to laboratory sample processing have been clearly defined. The in situ sectioning provided a means by which to investigate surface and subsurface microstructures and perform different analytical techniques on the same object, which minimizes sample destruction and avoids excessive manual handling and exposure of the specimen during analysis. Improvement in the morphological and compositional evaluation of the filaments has facilitated the development of a hypothesis regarding the metabolic pathway of the filamentous microfossils preserved in the Middle Devonian-aged Hollard Mound deposit, Anti-Atlas, Morocco. The results of this study demonstrate the potential of the FIB/SEM (scanning electron microscopy) system for detecting microbial-scale morphologies.

    Introduction There are limited studies on consumer behaviour toward counterfeit products and the determining factors that motivate willingness to purchase counterfeit items. Aim This study aimed to fill this literature gap through studying differences in individual ethical evaluations of counterfeit drug purchase and whether that ethical evaluation affected by difference in income. It is hypothesized that individuals with lower/higher income make a more/less permissive evaluation of ethical responsibility regarding counterfeit drug purchase. Materials and Methods To empirically test the research assumption, a comparison was made between people who live in the low-income country Sudan and people who live in the high-income country Qatar. The study employed a face-to-face structured interview survey methodology to collect data from 1,170 subjects and the Sudanese and Qatari samples were compared using independent t-test at alpha level of 0.05 employing SPSS version 22.0. Results Sudanese and Qatari individuals were significantly different on all items. Sudanese individuals scored below 3 for all Awareness of Societal Consequences (ASC) items indicating that they make more permissive evaluation of ethical responsibility regarding counterfeit drug purchase. Both groups shared a basic positive moral agreement regarding subjective norm indicating that influence of income is not evident. Conclusion Findings indicate that low-income individuals make more permissive evaluation of ethical responsibility regarding counterfeit drugs purchase when highlighting awareness of societal consequences used as a deterrent tool, while both low and high-income individuals share a basic positive moral agreement when subjective norm dimension is exploited to discourage unethical buying behaviour.

    Torque Teno virus (TTV) has been associated with non A-G hepatitis. The goal of this study was to estimate the infection rates and genotypic characteristics of TTV in the State of Qatar. A total of 644 blood samples representing different nationalities: (i) Qatari (118) and (ii) non-Qatari (526) nationals (mostly from Arab and South Eeast Asia countries) were tested for the presence of TTV DNA by nested PCR. The majority (573) of the blood samples belonged to healthy blood donors, whereas 54 and 53 of the blood samples belonged to patients infected with hepatitis B virus (HBV) and hepatitis C virus (HCV), respectively. The results obtained showed that the TTV infection rates in the healthy blood donors, and those infected with HBV or HCV patients were 81.4, 90.75 and 84.9%, respectively. Significant association between TTV viremia and age, or nationality was observed. Sequence analysis of PCR fragments amplified from the 5'-untranslated region (5'-UTR) of all (531) TTV positive samples showed that 65.5% (348/531) of the PCR fragment sequences were classified into main genogroup 3, followed by main genogroups 5 (24%), 2 (5.8%), and 1 (4.7%). Genogroup 4 was not detected among the our studied subjects. Phylogenetic and pairwise analyses using sequences from TTV viremic samples also showed an overall close similarity to the main genogroup 3. In conclusion, there was no significant difference in the rates of TTV detection among Qataris and non-Qataris and several genotypes, mainly genotype 3, were isolated.

    The Asian tiger mosquito Stegomyia albopicta (= Aedes albopictus) (Diptera: Culicidae), native to Asian forests, is a nuisance mosquito and is responsible for the transmission of arboviruses of public health importance, such as dengue, chikungunya and Zika viruses. It has colonized parts of all continents, except Antarctica, over the past 30-40 years. However, to date, the only records of S. albopicta in North Africa refer to occasional collections in 2010 and 2014 in Algeria. In early September 2015, S. albopicta larvae and adults were collected in a district of Rabat, Morocco. Morphological identification was confirmed by molecular analysis. This is the first record of this invasive mosquito in Morocco. A national surveillance programme will be implemented in 2016 to establish its geographical distribution in Morocco and to instigate control measures to prevent the establishment of new populations and the transmission of arboviruses.

    Erwinia amylovora causes economic losses that affect pear and apple production in Morocco. Here, we report comparative genomics of four Moroccan E. amylovora strains with the European strain CFBP1430 and North-American strain ATCC49946. Analysis of single nucleotide polymorphisms (SNPs) revealed genetic homogeneity of Moroccan's strains and their proximity to the European strain CFBP1430. Moreover, the collected sequences allowed the assembly of a 65 kpb plasmid, which is highly similar to the plasmid pEI70 harbored by several European E. amylovora isolates. This plasmid was found in 33% of the 40 E. amylovora strains collected from several host plants in 2009 and 2010 in Morocco.

  14. Irrigated Agriculture in Morocco: An Agent-Based Model of Adaptation and Decision Making Amid Increasingly Frequent Drought Events

    NASA Astrophysics Data System (ADS)

    Norton, M.

    2015-12-01

    In the past 100 years, Morocco has undertaken a heavy investment in developing water infrastructure that has led to a dramatic expansion of irrigated agriculture. Irrigated agriculture is the primary user of water in many arid countries, often accounting for 80-90% of total water usage. Irrigation is adopted by farmers not only because it leads to increased production, but also because it improves resilience to an uncertain climate. However, the Mediterranean region as a whole has also seen an increase in the frequency and severity of drought events. These droughts have had a dramatic impact on farmer livelihoods and have led to a number of coping strategies, including the adoption or disadoption of irrigation. In this study, we use a record of the annual extent of irrigated agriculture in Morocco to model the effect of drought on the extent of irrigated agriculture. Using an agent-based socioeconomic model, we seek to answer the following questions: 1) Do farmers expand irrigated agriculture in response to droughts? 2) Do drought events entail the removal of perennial crops like orchards? 3) Can we detect the retreat of irrigated agriculture in the more fragile watersheds of Morocco? Understanding the determinants of irrigated crop expansion and contractions will help us understand how agro-ecological systems transition from 20th century paradigms of expansion of water supply to a 21st century paradigm of water use efficiency. The answers will become important as countries learn how to manage water in new climate regimes characterized by less reliable and available precipitation.

    Background In Morocco, the main strategies of leishmaniasis vector control are based on environmental modifications. Use of local residual indoor spraying with synthetic pyrethroids is often envisaged. The need to evaluate this control method is essential. The current study was conducted to determine the efficacy of an alphacypermethrin IRS program against leishmaniasis vectors in an endemic area in the north of Morocco. Methods The survey was conducted in four neighbouring localities in three different districts in northern Morocco: Ait Chaib and Aichoun in Sefrou district, Bouassem (Boulmane) and Lmrouj (Taounate). Indoor residual spraying with alphacypermethrin at a dose of 30 mg/m2 was used in Ait Chaib and Lmrouj localities during 2010, 2011 and 2012, while localities of Aichoun and Bouassem were taken as control. In the four studied areas, sand flies were collected bimonthly from April to November in 2011 and 2012, using sticky traps, to determine their abundance and feeding pattern. Alphacypermethrin IRS were evaluated for their residual effect using the WHO cone bioassay test. Leishmaniasis incidence was estimated by passive and active case detection in each study area. Results Significant reductions in leishmaniasis incidence and in gravidity rate were observed when comparing sprayed and unsprayed localities. The residual activity of alphacypermethrin at the concentration used lasted 10 weeks after spraying. However, the abundance of sand flies was not significantly affected by alphacypermethrin IRS. Conclusion This study indicated that IRS has a significant impact on leishmaniasis transmission; therefore it could be recommended as an effective tool for leishmaniasis control in areas with high leishmaniasis transmission.

    Background Cystic echinococcosis (CE) is a neglected parasitic zoonosis with considerable socioeconomic impact on affected pastoral communities. CE is endemic throughout the Mediterranean, including Morocco, where the Mid Atlas is the most prevalent area for both human and animal infection. The highest hospital annual incidence of human CE is recorded in the provinces of Ifrane and El Hajeb. However, hospital-based statistics likely underestimate the real prevalence of infection, as a proportion of cases never reach medical attention or official records. Methodology/Principal findings In 2012, a project on clinical management of CE in Morocco was launched with the aims of estimating the prevalence of human abdominal CE in selected rural communes of the above mentioned provinces using ultrasound (US) screening and training local physicians to implement US-based focused assessment and rational clinical management of CE according to the WHO-IWGE Expert Consensus. A total of 5367 people received abdominal US during four campaigns in April-May 2014. During the campaigns, 24 local general practitioners received >24 hours of hands-on training and 143 health education sessions were organized for local communities. We found an overall CE prevalence of 1.9%, with significantly higher values in the rural communes of Ifrane than El Hajeb (2.6% vs 1.3%; p<0.001). CE cysts were predominantly in inactive stage, especially in older age groups. However, active cysts were present also in adults, indicating acquisition of infection at all ages. Province of residence was the only risk factor consistently associated with CE infection. Conclusions/Significance Our results show a high prevalence and on-going, likely environmental transmission of CE in the investigated provinces of Morocco, supporting the implementation of control activities in the area by national health authorities and encouraging the acceptance and divulgation of diagnosis and treatment algorithms based on imaging for

    The nearly complete skeleton of a large sauropod discovered at Wawmda (High Central Atlas of Morocco) in strata of Bathonian-Callovian age represents a new taxon: Atlasaurus imelakei n.g., n.sp. The sauropod appears to be closer to Brachiosaurus than any other known sauropod, but possesses (relative to the length of the dorsal vertebral column) a larger skull, shorter neck, longer tail and more elongated limbs. The presence of large sauropods of Middle Jurassic age is very important in understanding the history and the evolution of these Mesozoïc giants.

    In the present study, Mycobacterium tuberculosis complex (MTBC) clinical isolates from culture-positive TB patients in Morocco were studied by spoligotyping and 12-loci MIRU-VNTR typing methods to characterize prevalent genotypes (n = 219 isolates from 208 patients). Spoligotyping resulted in 39 unique patterns and 167 strains in 30 clusters (2-50 strains per cluster). Comparison with international database showed that 29 of 39 unique patterns matched existing shared spoligotype international types (SITs). Nine shared types containing 10 strains were newly created (SIT 2891 to SIT 2899); this led to the description of 69 SITs with 206 strains and two orphan patterns. The most prevalent spoligotype was SIT42 (LAM; n = 50 or 24% of isolates). The repartition of strains according to major MTBC clades was as follows LAM (46.1%)> Haarlem (26%) >ill-defined T superfamily (22.6%) and S clade (0.96%). On the other hand, Beijing, CAS (Central Asian) and EAI (East-African Indian) strains were absent in this setting. Subsequent 12-Loci MIRU typing resulted in a total of 25 SIT/MIT clusters (n = 66 isolates, 2-6 isolates per cluster), with a resulting recent transmission rate of 22.3%. The MIRU-VNTR patterns corresponded to 69 MITs for 138 strains and 46 orphan patterns. The most frequent patterns were MIT43 (n = 8), MIT9 (n = 7) and MIT42 (n = 7). HGDI analysis of the 12 MIRU loci showed that loci 10, 23 and 40 were highly discriminative in our setting. The results also underlined the usefulness of spoligotyping and MIRU-VNTR to detect mixed infections among certain of our TB patients. Globally, the results obtained showed that TB is almost exclusively transmitted in Morocco through evolutionary-modern MTBC lineages belonging to principal genetic groups 2/3 strains (Haarlem, LAM, T), with a high level of biodiversity seen by MIRU typing. This study provides with a 1st global snapshot of MTBC population structure in Morocco, and validates the potential use of spoligotyping in

    Samples of dust deposits were periodically collected from July 1, 1997 to January 30, 1999, at Souss-Massa basin, in the South of Morocco. Granulometrical, geochemical and mineralogical characterisations show that quartz, calcite and feldspars dominate the mineral contents of the dust deposit with a minor clay fraction. It indicates the mineralogical composition of dust collected in peri-Saharan regions. The material collected in the summer period is dominated by local dust against a mixture of local and proximal dusts in the winter period.
