  3. Water use efficiency studies of Acacia senegal (L.) Willd provenances in Sudan

    International Nuclear Information System (INIS)

    An experiment was conducted in 1989 to screen Acacia senegal L. Willd provenances collected from within the natural gum belt for high water use efficiency. Thirteen provenances were tested for water use efficiency and consequently 6 out of them were selected for further screening. The selection was based on their performance in the preliminary screening. Both the preliminary and the detailed study revealed that provenances 7, 3 and 11 combine high dry matter production with high water use efficiency. Water use efficiency and dry matter production appears to be negatively correlated with root length density and root/shoot ratios. Provenances 7 which exhibited the highest water use efficiency and dry matter yield had the lowest root/shoot ratio and also a low root length density. Based on these studies provenance 7 can be considered a suitable candidate for introduction into gum-belt of Sudan through for rehabilitation of this region. (author). 5 refs, 1 fig., 3 tabs

  4. Phosphorus use efficiency of the gum arabi tree (Acacia senegal (L) Willd) in Sudan

    International Nuclear Information System (INIS)

    This study was conducted to identify gum arabic tree (Acacia senegal L. Willd) provenances with high efficiency for phosphorus uptake and use. Thirteen provenances were collected from different habitats with the gum belt of the Sudan. A preliminary trial was conducted during the period 1989-1992 at the Gezira Agricultural Research Station in Wad Medani. This study revealed that there are clear genotypic differences in phosphorus use efficiency, nitrogen yield and dry matter production. All the provenances tested also exhibited a high ability for survival under the dry climatic conditions as prevailing in the gum belt of Sudan. Based on differences in phosphorus use efficiency observed in the preliminary study, 4 provenances were selected for a detailed study. Provenance 11 and 2 represented the highly efficient group, provenance 7 the moderately efficient group and provenance 13 the low efficient group. The detailed study revealed that provenance 11 is superior to all others in terms of biomass production as well as in phosphorus use efficiency. Although the ability to take up phosphorus was low, this was compensated by having a high root length density enabling the tree to take up a quantity of phosphorus similar to that taken up by other provenances. The high ability to convert the absorbed phosphorus into a greater quantity of dry matter made this provenance the best in phosphorus use efficiency. These results suggest that provenance 11 may be a suitable candidate to be introduced into the gum belt of Sudan in support of its rehabilitation programme. (author). 13 refs, 4 figs, 5 tabs

    Tomato is an important vegetable crop and its production is adversely affected by leaf curl disease caused by begomovirus. Leaf curl disease is a serious concern for tomato crops caused by begomovirus in Jeddah, Kingdom of Saudi Arabia. Tomato leaf curl disease has been shown to be mainly caused either by tomato leaf curl Sudan virus or tomato yellow leaf curl virus as well as tomato leaf curl Oman virus. Many tomato plants infected with monopartite begomoviruses were also found to harbor a symptom enhancing betasatellites. Here we report the association of tomato leaf curl Sudan virus causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia. The complete genome sequence analysis showed highest (99.9 %) identity with tomato leaf curl Sudan virus causing leaf curl disease in Arabian Peninsula. In phylogenetic relationships analysis, the identified virus formed closest cluster with tomato leaf curl Sudan virus. In recombination analysis study, the major parent was identified as tomato leaf curl Sudan virus. Findings of this study strongly supports the associated virus is a variant of tomato leaf curl Sudan virus causing disease in Sudan, Yemen and Arabian Peninsula. The betasatellites sequence analysis showed highest identity (99.8 %) with tomato leaf curl betasatellites-Amaranthus-Jeddah. The phylogenetic analysis result based on betasatellites formed closed cluster with tomato yellow leaf curl Oman betasatellites. The importance of these findings and occurrence of begomovirus in new geographic regions causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia are discussed. PMID:27366765

The work force totals 3 million. Senegal claims a population comprised of 5 ethnic groups and various others, 3 religious beliefs, and speaking 5 languages. No period of education is listed as compulsory, with the country overall experiencing 28% literacy. The infant mortality rate is 78/1,000, while life expectancy is 48 years. 1989 GDP was $5 billion, and was growing at the rate of 6%. 1988 per capita GDP was $630, with a 1989 inflation rate of 2%. Agriculture accounts for 22% of GDP, industry for 24%; 1990 international trade deficit totalled $209 million. Additional data are provided on Senegal's people, government, economy, international affiliations, defense, history, political conditions, principal government officials, foreign relations, and bilateral relations with the United States. Senegal suffers from a resource-poor economy vulnerable to environmental and international commodity price fluctuations. The country depends heavily on international donor assistance. 70% of the labor force is engaged in farming, with peanuts accounting for 1/2 of agricultural output. Agroindustry investment is planned to bring Senegal further along toward food self-sufficiency. Fishing, phosphate production, and tourism are all areas for economic growth. Economic reforms along with favorable weather in recent years have resulted in real GDP growth. Foreign investment is welcomed in Senegal, as demonstrated by revised terms set forth in the investment code of 1987. PMID:12178030

  8. Development of a Model for Estimation of Acacia Senegal Tree Biomass Using Allometry and Aster Satellite Imagery at Ennuhud, West Kordofan State, Sudan

    The current paper deals with the development of a biomass model for Acacia senegal trees by applying allometric equations for ground data combined with ASTER satellite data sets. The current study is conducted around Ennuhud area which is located in Ennuhud locality in West Kordofan State, Sudan. Primary data are obtained by application of random sampling around Ennuhud town where Acacia senegal tree species is abundant. Ten sample units are taken. Each unit contains five sample plots (15x15 m), one in the centre and the others in the four directions 100 m away from the centre forming a total of 50 sample plots. The tree coordinates, diameter/diameters (diameter at breast height ≥ 5 cm), height and crown diameters will be recorded. Sensor data were acquired from ASTER remote sensing satellite (29.03.2007 & 26.01.2011) and integrated with the in-situ data. The expected findings allow for the calculation of the mean diameter of trees. The tree above ground biomass (TAGB), tree below ground biomass (TBGB) and the tree total biomass (TTB) of Acacia senegal are computed consequently. Remotely sensed data are integrated with the ground data for creating the data base for calculating the correlation of the relationship between the two methods of data collection. The application of allometric equations is useful as a non-destructive method for biomass estimation by the application of remote sensing is recommended for biomass modelling over large areas.

    industrial sector reinvests part of its benefits, one can reasonably say that this sector could improve its performances in its traditional borders of production and maintenance. This will encourage enterprices concerned to pursue their development which is in straight line the process of economic and social development of Senegal. Regarding solar energy, the investments realised are negligible. But they are necessary and take part in the development process of the Senegalese rural community. This same applies to projects related to the protection of forest and community reforestation. Thus the installation of new and renewable forms of energies like solar energy as well as the reforestation projects are perfectly in line with the 9th Economic and Social Development Plan which is ongoing. This plan insists on the need to preserve the natural and forestry resources and to reinforce their potentialities. In this development strategy, the environment is identified as one of the most strategic sector which will ensure sustainable development. This is why this present project combines sectoral approaches from a more global perspective of actions undertaken (industry, PME, rural and urban zones etc..) convinced about the strong interdependence between the environment, energy and development. The different measures of mitigation options proposed here, will on the one hand compete with the accelaration of the electrification process of rural and village communities, and with sustainable economic develoment of these entities.

    An experiment was conducted to screen Acacia senegal (L.) Willd provenances collected from within the gum arabic belt, for their combined high water use efficiency (WUE) and high phosphorus use efficiency (PUE). Thirteen provenances were collected and their seedlings grown in a field naturally containing 22.1 kg/ha P. An additional 21.5 kg/ha P was applied to half the seedlings. Irrigation was applied when 75% of the available water was depleted. The results indicated that there was no significant response to the applied P, but that the provenances differed widely in their response to the limited water supply. Provenances collected from clayey soils had a higher WUE than those collected from sandy sites, probably because of better adaptation to the experimental site. (author). 2 figs, 4 tabs

    We examined the effects of intercropping with Acacia senegal (L.) Willd on growth and yield of sorghum (Sorghum bicolor L.),sesame (Sesamum indicum L.) and roselle (Hibiscus sabdariffa).Field experiments were conducted in El-Obeid Research farm (13°10' N; 30°12' E),North Kordofan State,Sudan,during 2002-2003 in an 11-year-old A.senegal plantation.The experimental design was randomized complete block design (RCBD) with four replications.Data were recorded for plant height (cm),fresh weight (kg·ha-1),dry weight (kg·ha-1),crop yield (kg·ha-1),and gum yield (kg·ha-1).We used Land Equivalent Ratios (LER) and simple financial analyses of gross surpluses to evaluate the productivity and profitability of the different treatments.The results indicated that A.senegal trees had a beneficial effect on crop performance and yield as well as gum yield.Significant differences (p < 0.05)were obtained for plant height,fresh weight,dry weight and crop yield.Therefore,yield of sorghum,sesame and roselle under intercropping system were 13.7%,23.8% and 20.9% higher than that obtained in the sole cropping system respectively.The highest yield increase was observed with sesame (23.8%).Gum yield (g/tree/picking) was significantly (p < 0.05) increased for sorghum,sesame and roslle under intercropping system.The highest yield of (298 g/tree/picking) was obtained when roselle was intercropped with A.senegal,while the least gum yield of (239 g·tree-1) was recorded in pure A.senegal plot.All the treatments gave land equivalent ratio (LER) of more than one-indicating the superiority of growing the field crops in intercropping over the sole cropping systems.The highest LER of 3.8 was obtained for sesame intercropped with A.senegal (Hashab),followed by 3.7,when sorghum was intercropped with A.senegal and 3.3 when roselle intercropped with A.senegal.All the treatments gave positive net revenues,the highest being for intercropped sorghum (558 SDG·ha-1) (SDG=Sudanese gienh

The main objective was to investigate the soil physical and chemical properties and yield of groundnut (Arachis hypogea, sesame (Sesamum indicum and roselle (Hibiscus sabdariffa of an Acacia senegal agroforestry system in comparison with the sole cropping system. Data were recorded for soil physical and chemical properties, soil moisture content, number of pods per plant, fresh weight (kg ha^−1 and crop yield (kg ha^−1. The treatments were arranged in Randomized Complete Block Design (RCBD and replicated four times.Significant differences (P < 0.05 were obtained for sand and silt content on both sites, while clay content was not significantly different on both sites. The nitrogen (N and organic carbon were significantly (P < 0.05 higher in the intercropping system in Eldemokeya Forest Reserve compared with sole cropping. Soil organic carbon, N and pH were not significant on El-Obeid site. Yet the level of organic carbon, N, P and pH was higher in the intercropping system.Fresh weight was significantly different on both sites. The highest fresh weight was found in the intercropping system. Dry weights were significantly different for sesame and roselle on both sites, while groundnut was not significantly different. On both sites intercropping systems reduced groundnut, sesame and roselle yields by 26.3, 12 and 20.2%, respectively. The reduction in yield in intercropping plots could be attributed to high tree density, which resulted in water and light competition between trees and the associated crops.

    The Sudan currently has a population of 18,618,000, with an annual rate of population growth of 3.1% and a rate of natural increase of 2.8%. Population size estimates for the year 2000 range from 32,064,000-33,762,000. The Sudan does not have an explicit policy to modify population growth, although the government is currently in the early stages of formulating a population policy. The current population growth rate is considered satisfactory because of the lack of population pressure on presently developed land, large areas of undeveloped land and unutilized agricultural potential, and low levels of open unemployment. However, the government seeks to modify spatial distribution to attain a better balance between population and resources. This will be accomplished through social infrastructure investments in rural and desert areas, regional development, sedentarization of nomads, development of new towns, and administrative decentralization. In addition, there is major concern with the high influx of undocumented workers and refugees and the significant emigration of skilled personnel. Life expectancy at birth stands at 45.1 years and the infant mortality rate is 131/1000. Current levels and trends of mortality are considered unacceptably high. Major health problems include schistosomiasis, malaria, malnutrition, infectious childhood diseases, and unsafe water. Primary health care is being prioritized to reduce regional differentials in health status and increase accessibility to health services. The total fertility rate has remained constant at 6-7 births/woman, but the government has been cautious with regard to family planning because of generally negative attitudes of Sudanese women toward birth control. Family planning has been integrated into maternal and child health services, although close to half of all ever-married women have never heard of family planning methods and only 6% of currently married fecund women are contraceptive users.

    Full Text Available Background: This article outlined the diversified history, the current state and future prospects of planning and evaluation in Senegal. Objectives: The aim was to nurture debate on the quest for a more ‘African-rooted evaluation practice’. Method: The article was based on an extensive grey literature review, the author’s involvement in SenEval and personal interviews. The literature on development evaluation and evaluation capacity development helped to frame the overall analysis. Results: Donor policies and practices have heavily influenced evaluation practice in Senegal but recent changes are shifting the emphasis to more context-specific practice. Some encouraging signs are the creation of a high-level commission for evaluation, the impulsion of results-based management in public administrations and the improved monitoring of poverty reduction strategies. Also promising are the individual evaluation capacities of some local actors and more diversified, professionalised training. The last flagship activities promoted by SenEval, a voluntary organisation of professional evaluators, and the prospects of its formalisation, could be a turning point in the development of evaluation in Senegal. Nevertheless, evaluation practice remains today focused more on accountability and controlthan on learning. Moreover, the institutional setup is not coherent and consolidated to ensure a perennial system to manage, conduct and use evaluations, ensuring their quality and inclusion in the policy cycle. Conclusion: We argued that SenEval has a significant role to play in boosting demand, strengthening the policy and institutional framework and promoting exchanges with the African and international evaluation community.

  7. Vegetation impoverishment despite greening: a case study from central Senegal

    2013-01-01

    Recent remote sensing studies have documented a greening trend in the semi-arid Sahel and Sudan zones of West Africa since the early 1980s, which challenges the mainstream paradigm of irreversible land degradation in this region. What the greening trend means on the ground, however, has not yet been explored. This research focuses on a region in central Senegal to examine changes in woody vegetation abundance and composition in selected sites by means of a botanical inventory of woody vegetation species, repeat photography, and perceptions of local land users. Despite the greening, an impoverishment of the woody vegetation cover was observed in the studied sites, indicated by an overall reduction in woody species richness, a loss of large trees, an increasing dominance of shrubs, and a shift towards more arid-tolerant, Sahelian species since 1983. Thus, interpretation of the satellite-derived greening trend as an improvement or recovery is not always justified. The case of central Senegal represents only one of several possible pathways of greening throughout the region, all of which result in similar satellite-derived greening signals.

Literacy was at the 50% level among men and 25% among women. Of the work force of 3 million, 66% are foreign workers. The labor force is distributed as follows: agriculture, 14%; industry, 11%; services, commerce, and government, 53%; construction, 20%; and oil and mining, 2%. The GDP was US$98.1 billion in 1985-86, with an annual growth rate of 8% and a per capita GDP of $9800. Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development. PMID:12178138

    The gum arabic belt in Sudan plays a significant role in environmental, social and economical aspects. This research was conducted in North Kordofan State, which is affected by modifications in conditions and composition of vegetation cover trends in the gum arabic belt as in the rest of the Sahelian Sudan zone. The objective of the paper is to study the classification, changes and analysis of the land use and land cover in the gum arabic belt in North Kordofan State in Sudan. The study used imageries from different satellites (Landsat and ASTER) and multi-temporal dates (MSS 1972, TM 1985, ETM+ 1999 and ASTER 2007) acquired in dry season. The imageries were geo-referenced and radiometrically corrected by using ENVI-FLAASH software. Image classification (pixel-based) and accuracy assessment were applied. Application of multi-temporal remote sensing data demonstrated successfully the identification and mapping of land use and land cover into five main classes. Forest dominated by Acacia senegal class was separated covering an area of 21% in the year 2007. The obvious changes and reciprocal conversions in the land use and land cover structure indicate the trends and conditions caused by the human interventions as well as ecological impacts on Acacia senegal trees. Also the study revealed that a drastic loss of forest resources occurred in the gum arabic belt in North Kordofan during 1972 to 2007 (25% for Acacia senegal trees). The study concluded that, using of traditional Acacia senegal-based agro-forestry as one of the most successful form in the gum belt.

    2012-07-01

    The gum arabic belt in Sudan plays a significant role in environmental, social and economical aspects. The belt has suffered from deforestation and degradation due to natural hazards and human activities. The research was conducted in North Kordofan State, which is affected by modifications in conditions and composition of vegetation cover trends in the gum arabic belt as in the rest of the Sahelian Sudan zone. The research investigated the possibility of identification, monitoring and mapping of the land use land cover changes and dynamics in the gum arabic belt during the last 35 years. Also a newly approach of object-based classification was applied for image classification. The study used imageries from different satellites (Landsat and ASTER) and multi-temporal dates (MSS 1972, TM 1985, ETM+ 1999 and ASTER 2007) acquired in dry season (November). The imageries were geo-referenced and radiometrically corrected by using ENVI-FLAASH software. Application of multi-temporal remote sensing data in gum arabic belt demonstrated successfully the identification and mapping of land use land cover into five main classes. Forest dominated by Acacia senegal class was separated covering an area of 21% and 24% in the year 2007 for areas A and B, respectively. The land use land cover structure in the gum arabic belt has obvious changes and reciprocal conversions between the classes indicating the trends and conditions caused by the human interventions as well as ecological impacts on Acacia senegal trees. The study revealed a drastic loss of Acacia senegal cover by 25% during the period of 1972 to 2007. The study come out with some valuable recommendations and comments which could contribute positively in using remotely sensed imagery and GIS techniques to explore management tools of Acacia senegal stands in gum Arabic belt.

  4. Comparison of the binding of the dyes Sudan II and Sudan IV to bovine hemoglobin

    International Nuclear Information System (INIS)

    Sudan dyes are widely used in industry, and sometimes illegally used as food additives despite their potential toxicity. In this work, the interactions of Sudan II and Sudan IV with bovine hemoglobin (BHb) were investigated by fluorescence, synchronous fluorescence, resonance light scattering (RLS), UV–vis absorption, circular dichroism (CD), and molecular modeling techniques. Binding of Sudan dyes to BHb could cause static quenching of the fluorescence, indicating changes in the microenvironment of tryptophan and tyrosine residues. The binding constants estimated for Sudan II and IV were 1.84×104 L mol−1 and 2.54×104 L mol−1, respectively, at 293 K (20 °C). Each protein molecule bound one Sudan molecule approximately. Sudan II and IV were held at the hydrophobic cavity of BHb mainly by hydrophobic interaction. The decrease of α-helix and the increase of β-sheet seen in the CD spectra revealed a conformational alteration of the protein. From all the results, we conclude that Sudan IV has a stronger impact on the structure and function of BHb than that of Sudan II. -- Highlights: • Spectroscopic results show interaction details of Sudan II and IV with BHb. • The interaction of BHb with Sudan dyes is spontaneous with a 1:1 stoichiometry. • Sudan II and IV are located at the hydrophobic cavity of the BHb, and form complexes via hydrophobic interaction. • A stronger influence of bovine hemoglobin is caused by Sudan IV than that of Sudan II

  5. Senegal's national policy to combat climate change

    International Nuclear Information System (INIS)

    Senegal's participation in the Earth Summit meeting in Rio in 1992 demonstrated its national political stand towards environmental causes. An initiative was taken to educate the population on greenhouse gas (GHG) emissions in relation to different sectors, including the energy sector, transportation, agriculture, forestry and waste management. Later, a group of negotiators followed the works of subsidiary bodies of the Kyoto Agreement. As a non-Annex 1 developing country, Senegal is not required to reduce GHG emissions as are Annex 1 countries. Therefore, Senegal has used judicial tools to benefit from the transfer of clean technologies. The implementation of Senegal's national adaptation action plan has involved global organizations, sectorial studies, public consultations, prioritization and project formulation. The action plan addresses concerns such as water resources, variation in precipitation, drought, agriculture and its vulnerability, and negative impacts due to climate change. The technical solutions include the promotion of agroforestry technologies; crop diversification; water conservation; community wood use; and, prevention of bush fires. Since several geographical regions within Senegal are also affected by global warming, policies are being formulated to protect humid zones and help in the fight against invasive species. Senegal imports much of its energy sources. Households rely on wood and coal for energy. New measures are being adapted and new sustainable technologies are being proposed for fireplaces, better recycling, and better landfill sites. 8 figs

    International Nuclear Information System (INIS)

    In this research project, an inventory for the different radioisotopes that were imported by public and private sectors of Sudan in the period between ( 2007-2011) has been set up. These organizations import the appropriates for different but in general we classify them into these applications: Medical, Industrial, Agricultural and Research. However, each broad discipline is subdivided into subgroups. This inventory will help those who are willing to establish research reactors in Sudan on the type and power of the reactors to be purchases according to the actual needs of Sudan with forecasting of the near and for future needs. Also the expenditure that has been spent by these organizations have been estimated for most of the radioisotopes. It was observed that almost 50% of the expenditure went for the fright charges as these radioisotopes need special handling and care by installing a research reactor in Sudan, the cost of purchasing will be cut down several folds. Also it will help in availability of the radioisotopes with very short half lives (hours to days). This will be reflected in the cut down the cost of tests and provision of new tests.(Author)

    1985-01-01

    Sudan is surrounded by eight countries and has marked movement of population across its borders. At one time yaws and syphilis were important public health problems in the Sudan. Following the wide use of penicillin, both diseases were much reduced in prevalence and were no longer public health problems. However, the extensive population movement and particularly the huge influx of refugees across the border pose important potential hazards. The rapid urbanization and the social and cultural changes that followed economic development affected family ties and community behavior and resulted in a marked increase in the prevalence of sexually transmitted diseases, including syphilis. It is difficult to know the true magnitude of the problem because of the poor health information system and coverage. Improvement of the surveillance system is urgently needed, and more attention needs to be paid to treponemal infections. This entails improvement in health services and training of health personnel.

  14. Forestry policy and charcoal production in Senegal

    International Nuclear Information System (INIS)

    This paper examines the historical, social and political-economic dynamics of environmental policy implementation in Senegal's charcoal market. It explores the relationship between urban demand for charcoal and its rural environmental consequences. It focuses on the ways in which the social and political-economic relations within the market and between the market and state shape production, exchange, regulation, and ultimately the social and econological consequences of charcoal production and use. The article begins by characterizing the patterns of woodfuel supply and use in Senegal and by recounting the historical perception and response to environmental problems associated with the woodfuel trade. It describes the social and economic organization of production and exchange, followed by an analysis of policy implementation. It also shows that where social relations dominate production and exchange, environmental policy making and implementation will be an iterative process. Sustainable resource management is not implemented once and for ever, but will come and go. (author)

  15. Risk analysis. HIV / AIDS country profile: Senegal.

    Science.gov (United States)

    1996-12-01

    Since the first acquired immunodeficiency syndrome (AIDS) case was confirmed in 1986, Senegal has conducted an aggressive prevention campaign. Senegal's National AIDS Committee has noted the contributions of poverty and migration to the spread of AIDS. By June 1994, 1297 AIDS cases had been reported and an estimated 500,000 people (1.4% of the population) were infected with human immunodeficiency virus (HIV)-1 and 2. The highest rate of HIV infection (14%) exists among commercial sex workers. At present, HIV/AIDS cases are concentrated in Dakar, Kaolack, the Matam region, and Ziguinchor; however, the growing importance of inter-regional trading is expected to spread HIV to the smaller towns and rural areas. Also salient is the recent devaluation by 50% of the CFA franc, which has reduced the public sector workforce and led many poor urban residents into commercial sex work. CFA devaluation has made Senegal attractive to tourists and business visitors--another factor responsible for growth of the legalized commercial sex industry. Although sex workers are instructed in condom use and tested annually for HIV, only 850 of the 2000 registered sex workers have reported for check-ups, and the majority of prostitutes are unregistered. Senegal's AIDS Plan for 1994-98 focuses on care of AIDS patients, pressures placed on family structures by HIV, and AIDS-related erosions in the status of women. Each health service region has its own local plan for AIDS/HIV and sexually transmitted diseases, supervised by a regional committee. Public education has involved outreach to religious leaders, promotion of affordable condoms, and distribution of over 75,000 leaflets to key target populations. About US $16 million of the $25,688,875-budget HIV/AIDS program for 1994-98 was pledged by external donors. PMID:12320531

The household was the basic unit of data collection; ten villages were selected as study localities. Ten respondents from each village were randomly chosen for the interview. Frequency distribution results showed that almost all the respondents have a particularly favourable perception of the community forestry programmes implemented and they perceive the best type of management for running these forests which is to be owned and managed by them. They participated in different programe activities and willing to further participation in tree planting activities. Women have possessed positive attitudes towards community forestry although they were not fully involved in community forestry Practices. Stepwise multiple linear regression analysis showed a statistical significant relation between some selected variables (Respondents age, educational level, main occupation, respondents indigenous knowledge, family uses of different forestry products, awareness of causes of forest destruction and finally respondents awareness of environmental problems exerted important influences on the attitudes and participation of respondents. This study suggests that the project and the forest services should continue addressing local development needs, encourage women's participation in community forestry, and work toward dispute settlement of community forest-user groups, if it wants to win the support of local communities for long-term environmental conservation goals.

  4. Environment of paleowater in Sudan

    International Nuclear Information System (INIS)

    Many natural and environmental developments created the conditions for paleowater occurrence in Sudan and possibly other areas. The major developments include: geological, structural and climatic. The geological environment includes the formation of Basement Complex (BC), which are the oldest rocks emplaced during Pre-Cambrian to the early Jurassic followed by the severe erosion, magmatism and deformation during the Jurassic. The uncomfortable deposition of the sedimentary rocks started in the Paleozoic and continued in association with the tectonic activities. Structural features resulted from the frequent tectonic activities controlled the configuration and geographical distribution of the sedimentary basins. The NW Central African Shear Zone CASZ, slip fault Wrench Strike to the West of the CASZ and the Garaf Strike Slip fault led to the establishment of depressions and deposition of the Paleozoic and Mesozoic sediments forming the sedimentary basins in Northwest (Sahara), in Southwest (Bagara) and in the east central (R Atbra)of Sudan respectively. The paleoclimatic investigations in the region covering: Lake Chad, the Nile system, Ethiopian Plata, Libya and Egypt suggested humid conditions between 40,000 and 3,000 Bp. The wet period was interrupted by dry periods. The early wet periods were recorded in Lake Chad. The estimated age of Paleowater cluster between 30,000-20,000 and 10,000 and 3000 BP and few ages between 10,000 and 20,000 PB in agreement with the defined dry period between 20,000 and 13,000 BP. The recharge of the Nubian aquifer remains a debatable topic. The so far conducted studies using environmental isotopes and hydrochemistry on the basis of conventional approaches suggest. The infiltration rate of water from the rainfall is estimated at 0.4 and 1.0 mm/y in the arid zones in the north (R Atbra Basin) and increases up to 10.0mm/y in the relatively wet areas in the south (Bagara Basin). The lateral recharge from the Nile system is evident up to

  6. Factors Affecting Adoption of Agroforestry Farming System as a Mean for Sustainable Agricultural Development and Environment Conservation in Arid Areas of Northern Kordofan State, Sudan

    International Nuclear Information System (INIS)

    Arid and semi-arid areas represent about 60 percent of Sudan total area. One of the main environmental problems in the arid and semi-arid areas is diffraction's which reduces the natural potential of the already fragile ecosystems and renders rural people vulnerable to food shortages, the vagaries of weather and natural disasters. Deforestation which is considered one of the most critical environmental problems facing the world is one of the main causes of diffraction's. Between the years 1990 and 2005 Sudan lost about 8.8 millions hectares of forests, which represents 11%, of its forests mainly because of subsistence activities such as overgrazing, trees cutting and expansion of traditional agriculture. One of the areas that are very much affected by diffraction's is Northern Kordofan State. To rescue the situation the government of Sudan, with assistance from the United Nations Development Program (UNDP) and some donors, implemented a project that aimed primarily at restocking Acacia Senegal trees in Northern Kordofan State. This study is intended to explore the factors that caused differential rate of farmers' adoption rate of the Acacia Senegal based agroforestry farming system. The study data was collected from a clustered random sample of 300 farmers, through face to face interviews using a questionnaire that was pre-tested and validated. Frequency distribution and multiple regression analysis were used to analyze the data. It has been found that farmers' adoption of agroforestry farming system in Northern Kordofan state was significantly affected by the farmers' level of formal education, contact with extension agents, level of environmental awareness, cosmopoliteness, total area of owned land and extent of social participation.

    Full Text Available Application of new and renewable sources of energy available in Sudan is now a major issue in the future energy strategic planning for the alternative to the fossil conventional energy to provide part of the local energy demand. Like many of the African leaders in renewable energy utilisation, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios for the new century emphasise the untapped potential of renewable resources are needed. Rural areas of Sudan can benefit from this transition. The increased availability of reliable and efficient energy services stimulates new development alternatives. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale plant especially for use in remote rural areas.

    Summer rains in western and southern Sudan have declined by 10-20 percent since the mid-1970s. Observed warming of more than 1 degree Celsius is equivalent to another 10-20 percent reduction in rainfall for crops. The warming and drying have impacted southern Darfur and areas around Juba. Rainfall declines west of Juba threaten southern Sudan's future food production prospects. In many cases, areas with changing climate are coincident with zones of substantial conflict, suggesting some degree of association; however, the contribution of climate change to these conflicts is not currently understood. Rapid population growth and the expansion of farming and pastoralism under a more variable climate regime could dramatically increase the number of at-risk people in Sudan over the next 20 years.

    2002-08-01

    Between 1990 and 2001, the laboratory of Paludologie of IRD at Dakar collected over 5,500 snakes from all over Senegal. By studying this collection, an entirely new species was discovered for science and eight new species for Senegal. The presence of many specimens of rare species and the great number of localities from which snakes were collected also allowed us to solve several delicate taxonomic problems and better to specify the biogeography of Senegalese snakes. Currently, the presence in Senegal of at least 55 different species has been established with certainty. The data collected simultaneously on the burden of snakebites for public health shows considerable differences according to geographic area, with populations from south-eastern Senegal being more exposed to the risk of death by snakebite.

    Full Text Available Objectives: To review the studied risk factors that linked to aetiology of oral cancer in the Sudan. There have been numerous reports in the increase in the incidence of oral cancer from various parts of the world. A recent trend for a rising incidence of oral cancer, with the absence of the well established risk factors, has raised concern. Although, there are inconsistent data on incidence and demographical factors, studies suggest that the physiologic response to risk factors by men and women vary in different populations.Material and Methods: This review principally examines 33 publications devoted to aetiology of oral cancer in the Sudan, in addition to some risk factors that are commonly practiced in the Sudan.Results: Several studies examining risk factors for oral cancer include tobacco use (Smoked and Smokeless, alcohol consumption, occupational risk, familial risk, immune deficits, virus infection and genetic factors.Conclusions: Toombak use and infection with high risk Human Papilloma Virus (HPV were extensively investigated and linked to the aetiology of oral cancer in Sudan.

  14. The Eradication of Rinderpest from Southern Sudan

    International Nuclear Information System (INIS)

    In 1994, Veterinaires Sans Frontieres (VSF) Belgium was one of the NGOs that joined the Operation Lifeline Sudan (OLS) Livestock Programme coordinated by the United Nations Children's Fund (UNICEF) in conflict-affected southern Sudan. The objective of the programme was to improve household food security through the control of rinderpest and the establishment of community-based animal health services. VSF Belgium trained and supported community-based animal health workers (CAHWs) in several agropastoralist communities of southern Sudan. The CAHWs carried out rinderpest vaccination using heat-stable vaccine, and provided vaccinations and treatments for other important diseases of cattle, sheep, goats and poultry. In 1996, VSF Belgium set up a training centre for mid-level animal health workers, to provide a cadre of animal health auxiliaries (AHAs) as CAHW supervisors and field coordinators. As a result of the widespread vaccination efforts, rinderpest outbreaks decreased and apparently stopped. The last confirmed rinderpest outbreak was in 1998, although there was a suspected but unconfirmed outbreak in 2001. About this time, FAO-GREP advised the Republic of Sudan to stop vaccinating and to enter the surveillance phase of the OIE Pathway to freedom from rinderpest.

Conclusions: * Summer rains have remained steady in Senegal over the past 20 years but are 15 percent below the 1920-1969 average. * Temperatures have increased by 0.9° Celsius since 1975, amplifying the effect of droughts. * Cereal yields are low but have been improving. * The amount of farmland per person is low and declining rapidly. * Current population and agriculture trends could lead to a 30-percent reduction in per capita cereal production by 2025.

  17. Hyperlipidaemia in Saudi Arabia

    International Nuclear Information System (INIS)

    Objective was to determine the prevalence of hyperlipidemia among Saudis of both genders in rural and urban communities. Selected Saudis in the age group of 30-70 years were studied over a 5-year period between 1995 and 2000 in Saudi Arabia. Data were obtained from history, physical examination and analysis of fasting plasma lipids. The data were analyzed to classify individuals with hypercholesterolemia (HC) (total cholesterol >=5.2 mmol/l) and hypertriglyceridemia (HT) (total triglycerides >=1.69 mmol/l). Logistic regression analysis was performed to provide a risk assessment model and correlation with other coronary artery disease (CAD) risk factors. The number of study samples included in the final analysis was 16,819. The prevalence of HC was 54% with mean cholesterol level of 5.4+-1.52 mmol/l. Prevalence of HC among males was 54.9% and 53.2% for females, while 53.4% among urban Saudis and 55.3% for rural Saudis. Hypertriglycemia prevalence was 40.3% with mean triglycerides level of 1.8+-1.29 mmol/l. Males had statistically significant higher HT prevalence of 47.6% compared to 33.7% in females (p<0.0001). Hyperlipidemia is reaching higher prevalence rates in KSA. This finding may suggest that CAD will soon be a major health problem. Reduction in obesity by adopting healthier eating problem habits and increasing physical activity are of considerable importance to our community. (author)

  20. Saudi Arabia : emerging with influence

    International Nuclear Information System (INIS)

    Energy and the Saudi economy were discussed with reference to reserves, oil prices, gross domestic product co-movements, and gas resources and development. In particular, this presentation reviewed the emergence and prospects of the petrochemical industry of Saudi Arabia using statistical, institutional and economic analyses relying on a wide range of data sources. Saudi Arabia has the world's largest oil reserves, at 263 billion barrels. In the 1990s, more than 54 Tcf of non-associated gas reserves were added to Saudi Arabia's resource base, more than doubling its proven non-associated gas reserves to approximately 97 Tcf. With 138 Tcf of associated gas reserves, Saudi Arabia holds the fourth largest gas reserves in the world at nearly 235 Tcf. First, this presentation identified and evaluated the endowments as well as the institutional and strategic forces that are driving the growth of the petrochemical industry in Saudi Arabia. Some of the economic, technical and geopolitical factors that influenced the increase in oil prices between 2003 and 2005 were also identified. The dual relationship between the Saudi petrochemical industry and long term economic performance of the Saudi economy were illustrated within a broad domestic economic diversification policy objective. The future growth prospects and challenges facing the Saudi petrochemical industry were also evaluated with respect to the evolving economic reform policies and Saudi international commitments. Potential implications for the petrochemical industry in North America were also identified, in terms of technology transfer and having Saudi Arabia secure the markets in order to meet its commitment to the World Trade Organization. tabs., figs

  1. Methods for Extraction and Charaterization of Tannins from Some Acacia Species of Sudan

    2016-06-01

    Full Text Available The study is aimed to analyze and compare extraction methods of tannins from three common Acacia species of Sudan. The Acacia species selected were Acacia nilotica, Acacia seyal and Acacia senegal. Bark samples from bulk collections of the three Acacia species were extracted with water, 80% methanol and 70% acetone. Two sets of extraction were made, one by boiling and a second by shaking the samples in the respective solvents for eight hours at room temperature. Although the amount of material extracted by these two procedures did not differ greatly (P > 0.05, 70% acetone was a more efficient solvent than either water or 80% methanol. The tannins of mature fruits extract of Acacia nilotica were identified by using Thin Layer Chromatography (TLC, Ultraviolet and Infrared spectroscopy. Comparisons of absorption spectra and TLC of the reference tannins and some phenolics with that of Acacia nilotica extracts revealed the presence of both condensed and hydrolyzable tannins, since it consists of catechin, tannic and gallic acids. Catechin considered to be the phenolic precursor of condensed tannins. Hydrolysis of Acacia nilotica extract, tannic and gallic acids by butanolic-hydrochloric acid yielded gallic acid which is considered to be a chemical precursor of hydrolyzable tannins

  14. Mapping the potential risk of mycetoma infection in Sudan and South Sudan using ecological niche modeling.

    2014-10-01

    Full Text Available In 2013, the World Health Organization (WHO recognized mycetoma as one of the neglected tropical conditions due to the efforts of the mycetoma consortium. This same consortium formulated knowledge gaps that require further research. One of these gaps was that very few data are available on the epidemiology and transmission cycle of the causative agents. Previous work suggested a soil-borne or Acacia thorn-prick-mediated origin of mycetoma infections, but no studies have investigated effects of soil type and Acacia geographic distribution on mycetoma case distributions. Here, we map risk of mycetoma infection across Sudan and South Sudan using ecological niche modeling (ENM. For this study, records of mycetoma cases were obtained from the scientific literature and GIDEON; Acacia records were obtained from the Global Biodiversity Information Facility. We developed ENMs based on digital GIS data layers summarizing soil characteristics, land-surface temperature, and greenness indices to provide a rich picture of environmental variation across Sudan and South Sudan. ENMs were calibrated in known endemic districts and transferred countrywide; model results suggested that risk is greatest in an east-west belt across central Sudan. Visualizing ENMs in environmental dimensions, mycetoma occurs under diverse environmental conditions. We compared niches of mycetoma and Acacia trees, and could not reject the null hypothesis of niche similarity. This study revealed contributions of different environmental factors to mycetoma infection risk, identified suitable environments and regions for transmission, signaled a potential mycetoma-Acacia association, and provided steps towards a robust risk map for the disease.

  15. Prediction of temperature and precipitation in Sudan and South Sudan by using LARS-WG in future

    Global warming has brought great pressure on the environment and livelihood conditions in Sudan and South Sudan. It is desirable to analyze and predict the change of critical climatic variables, such as temperature and precipitation, which will provide valuable reference results for future water resources planning and management in the region. The aims of this study are to test the applicability of the Long Ashton Research Station Weather Generator (LARS-WG) model in downscaling daily precipitation and daily maximum (Tmax) and daily minimum (Tmin) temperatures in Sudan and South Sudan and use it to predict future changes of precipitation; Tmin and Tmax for nine stations in Sudan and South Sudan are based on the SRA2 scenario of seven General Circulation Models (GCMs) outputs for the periods of 2011-2030, 2046-2065, and 2080-2099. The results showed that (1) the LARS-WG model produces good performance in downscaling daily precipitation and excellent performance in downscaling Tmax and Tmin in the study region; (2) downscaled precipitation from the prediction of seven GCMs showed great inconsistency in these two regions, which illustrates the great uncertainty in GCMs' results in the regions; (3) predicted precipitation in rainy season JJA (June, July, and August) based on the ensemble mean of seven GCMs showed a decreasing trend in the periods of 2011-2030, 2046-2065, and 2080-2099 in Sudan; however, an increasing trend can be found in SON (September, October, and November) in the future; (4) precipitation in South Sudan has an increasing trend in most seasons in the future except in MAM (March, April, and May) season in 2011-2030; and (5) predictions from seven GCMs showed a similar and continuous increasing trend for Tmax and Tmin in all three future periods, which will bring severe negative influence on improving livelihoods and reducing poverty in Sudan and South Sudan.

    Assessment of water availability and demand in Lake Guiers, SenegalWater resources are critical to economic growth and social development. In most African countries, supply of drinking water to satisfy population needs is a key issue because of population growth and climate and land use change. During the last three decades, increasing population, changing patterns of water demand, and concentration of population and economic activities in urban areas has pressurize Senegal's freshwater resources. To overcome this deficit, Senegal turned, to the exploitation of the Lake Guiers. It is the sole water reservoir which can be used extensively as a stable freshwater. Its water is use for irrigating crops and sugar refinery and as a drinking water resource for urban centres, including Dakar, the capital city of Senegal, as well as for the local population and animal herds. To ensure sustainability, a greater understanding of Lake Guiers's water resources and effective management of its use will be required. In this study we developed and quantified future water situation (water availability and demand) in Lake Guiers under scenarios of climate change and population growth until 2050, using the water management model WEAP (Water Evaluation And Planning system). The results show that the pressure on Lake Guiers's water resources will increase, leading to greater competition between agriculture and municipal demand site. Decreasing inflows due to climate change will aggravate this situation. WEAP results offer basis to assister lake Guiers water resources manager for an efficient long-term planning and management.

    A survey form provided by the Joint FAO/IAEA Division was used to collect data on village poultry production in the Sudan. The production system in the households was based on scavenging indigenous domestic chickens, at times accompanied by pigeons, guinea fowls, ducks or turkeys. The average flock size was 18.8 birds and included 44.3% hens, 10% cocks, 20% growers and 24.8% chicks. The hen to cock ratio was 4.4:1. Average egg production was 3.1 per hen per month, of which 76% were incubated by hens. About 78% of incubated eggs hatched of which 75% survived the brooding period. Approximately half of the households provided the chickens with housing. Around 25.7% of interviewed households used chicken manure as fertilizer. While scavenging, chickens fed on insects, grass, vegetables and kitchen wastes. Feed supplements included sorghum, millet and sometimes wheat bran and alfalfa. The ownership of village chickens was shared between all gender categories and all were involved in the management of the birds. The major constraints to village poultry production in the Sudan were identified and included inadequate health care, poor production, inappropriate housing and poor knowledge of poultry management.

  6. Histopathological patterns of nasopharyngeal carcinoma in Sudan

    International Nuclear Information System (INIS)

    Objective was to study histopathological patterns of nasopharyngeal carcinoma (NPC) in Sudanese patients and to compare them with the internationally published series. A retrospective review for records of NPC patients treated in the Institute of Nuclear Medicine, Molecular Biology and Oncoloy (INMO), Wadmedani, Sudan during the period 2000-2005 was conducted. Parameters included in the review were histological types of NPC according to the World Health Organization (WHO) classification, age, gender, locality, ethnicity and stage. All cases of NPC with positive histology were included while other types of histology lymphoma, sarcoma were excluded. The SPSS software was used for data entry and analysis. Total number of patients with NPC was 103. Age range from 11-82 years, median was 41 years and mean was 45.5 years of age. Male, female ratio was 2:1. The WHO histology type-3 was 73.8% of cases, WHO type-2 was 26.2%, and there was no case of WHO type1 found in this study population. Neck swelling is the most common presenting system 77.8%. Patterns of NPC classification resembles those seen in endemic areas like South China. Dominanant histology was WHO-type 3. Identifying risk factors for NPC in Sudan is required. (author)

    Objective: To investigate the epidemiological factors of tuberculosis (TB) in eastern Sudan. Methods:The socio-demographic and clinical data was retrieved from the database at Kassala hospital during the year of 2011. The medical file of consequent patients who was discharged from the same ward in the hospital was reviewed to act as control for the TB patients. Results:A total of 670 patients were registered at Kassala hospital with clinical, laboratory and radiological evidence proven TB. Pulmonary TB accounted for 73.4%while extra-pulmonary TB was reported in 26.6%of all TB patients. The mean age (SD) was not significantly different between the cases and controls (670 in each arm). TB patients were those who had less education, and the infection more likely common among male patients. Conclusions: Intervention from outside the health field in particular awareness of associated risk factors and improvement of the educational level potentially will strengthen TB control.

    Four eucalypts (Eucalyptus camaldulensis, Eucalyptus microtheca, Eucalyptus tereticornis and Eucalyptus citriodora) grown in Sudan were examined for their suitability for pulping and papermaking with different alkaline methods. Their physical, morphological and chemical characteristics are reported. The pulping trials with E. citriodora and E. tereticornis were carried out using the kraft-AQ, soda-AQ, modified AS/AQ (ASA), ASAM and kraft methods. For the other two species, only the ASAM and the kraft process were applied. ASAM pulping gave the best results in terms of yield, degree of delignification, mechanical and optical pulp properties. The best pulps, obtained in kraft and ASAM cooking of E. citriodora, were bleached to 88% ISO brightness in a totally chlorine free bleaching sequence (OQ1O/PQ2P). The bleached pulps, especially the ASAM pulp, showed good papermaking properties and would be suitable for manufacture of writing and printing grades of paper. PMID:15935655

  18. Radiochemical studies on environmental radioactivity in Sudan

    International Nuclear Information System (INIS)

    Measurements of uranium and thorium isotopes, 226 Ra, 210 Po, 228 Ra, 40 K and fallout radionuclide 137 Cs in soil samples collected from different districts in Sudan, rock phosphate samples collected from the uro and kurun rock phosphate deposits in the eastern part of the Nuba mountains in Western Sudan, and surface marine sediments and marine organisms collected from the sudanese coastal waters of the Red Sea have been made using a high resolution gamma-spectrometry, radiochemical separation and α spectrometry. The external exposure due to γ radiation from the ground has been calculated. The average exposure was found to be 45.4 ± 21.3 nGy/h, corresponding to the annual dose equivalent of 278 μSv/y. With the exception of some areas, the calculated exposure falls within the global wide range of outdoor radiation exposure given in the UNSCEAR publications. The nation-wide average concentrations of 226 Ra, 238 U, 232 Th, 40 K and 137 Cs determined were 31.6 ± 27, 20.1 ± 16.4, 19.1 ± 8.1, 280.3 ± 137.6 and 4.1 ± 4.3 Bq/Kg, respectively. This shows that there is little contamination due to fallout radioactivity at survey sites. The exchangeable radium fraction constitutes 19-24% of the total radium content. The data show that 238 U and its decay products are the principal contributors of radioactivity in both phosphate deposits at Uro and Kurun. The equivalent mass concentrations of uranium in the Uro rock phosphate fall within the range that could be economically recovered as the by-product of fertilizer industry. The mean activity concentrations weighted by average agricultural consumption of 300 kg/ha of untreated ground rock fertilizer resulted in an annual distribution of 120.63 Bq Ra/m2 with Uro rock and 12.97, 0.21 and 4.24 Bq/m2 respectively, with Kurun rock fertilizer. The external radiation exposure over agricultural areas was estimated 23.41 x 10 -9 Gy/h and 2.59 x 10 -9 Gy/h at 1 m above ground level for Uro and Kurun rock phosphate fertilizers

  19. Sudan: the human price of oil

    International Nuclear Information System (INIS)

    This series of eight information bulletins by Amnesty International is intended to draw attention to the link between the massive human rights violations by the security forces of the Government of Sudan and various government-allied militia forces, and the oil operations by foreign companies (which include Canada's Talisman Energy, Denim Pipeline Construction Ltd., and Roll'n Oil Field Industries). The human rights violations cited by Amnesty International include atrocities and the forcible internal displacement of large populations of local people living in the oil fields and surrounding areas. It is alleged that the foreign oil companies involved in this lucrative operation expect the Sudanese government to provide a secure environment and protect oil company staff and assets, and turn a blind eye to human rights violations by the government security forces in the name of protecting the security of the oil-producing areas. In raising awareness of the problem, Amnesty International hopes to establish a dialogue with the foreign oil companies and sensitize them to their responsibilities to promote a better human rights environment in the areas where they are active in oil exploration and extraction. The information bulletins provide a background to the problem; detail the human rights violations committed in the name of oil; establish the link between oil, weapons purchases by the Sudanese government and human rights violations; describe the oil companies and their responsibilities and international standards on internal displacement of populations; and makes recommendations to the Government of Sudan, to the armed opposition groups, to the oil companies and to the international community at large to bring an end to the human rights violations that over the last three decades have cost tens of thousands of lives and displaced hundreds of thousands of people

    Full Text Available Background: Hypospadias is one of the commonest penile abnormalities in new born males, and occurs as a result of a birth defect resulting in a urethral opening anywhere from the glans penis along the ventral aspect of the shaft of the penis up to the scrotum or the perineum in extreme cases. The condition has a huge impact on the patient′s psychological, emotional and sexual well being. This study aimed to evaluate the current trend in the treatment of hypospadias in Sudan. Materials and Methods: The was a retrospective study done in Elribat university hospital, department of Paediatrics surgery, for patients who underwent hypospadias surgical repair in the period January 2006 to June 2007. Results: There were 50 patients in this study. Regional distribution of the patients showed that 52% of the patients live in Khartoum state, the capital, while 48% were from the peripheries; 12% of patients had family history of similar condition (Hypospadias and 54% were of low socioeconomic status. Anterior hypospadias was the commonest type (46%, and associated chordee occurred in most of the patients (88%. The most common associated anomalies found were undescended testicles (20% and inguinal hernia only in 2%. The most common type of repair was MAGPI (meatal advancement and glanuloplasty with 42% of cases, anterior hypospadias commonest type with 46% of cases, 12% of cases had a family history of the condition and an overall complication rate of 26%. Chordee was the most prevalent association in 88% of cases. Conclusion: There is a high familial tendency for hypospadias in Sudan. Associated chordee and other anomalies are in keeping with other reports. Corrective surgery for hypospadias is associated with high complication rate in our setting. Collaboration between surgical specialties such as plastic surgeons, paediatrics urologist and general surgeons may improve the present complication scenario.

    In Senegal, great amounts of data are daily generated by medical activities such as consultation, hospitalization, blood test, x-ray, birth, death, etc. These data are still recorded in register, printed images, audios and movies which are manually processed. However, some medical organizations have their own software for non-standardized patient record management, appointment, wages, etc. without any possibility of sharing these data or communicating with other medical structures. This leads to lots of limitations in reusing or sharing these data because of their possible structural and semantic heterogeneity. To overcome these problems we have proposed a National Medical Information System for Senegal (SIMENS). As an integrated platform, SIMENS provides an EHR system that supports healthcare activities, a mobile version and a web portal. The SIMENS architecture proposes also a data and application integration services for supporting interoperability and decision making. PMID:27577338

    The communication and migration patterns of a country are shaped by its socioeconomic processes. The economy of Senegal is predominantly rural, as agriculture employs over 70% of the labor force. In this paper, we use mobile phone records to explore the impact of agricultural activity on the communication and mobility patterns of the inhabitants of Senegal. We find two peaks of phone calls activity emerging during the growing season. Moreover, during the harvest period, we detect an increase in the migration flows throughout the country. However, religious holidays also shape the mobility patterns of the Senegalese people. Hence, in the light of our results, agricultural activity and religious holidays are the primary drivers of mobility inside the country.

  5. Saudi Arabia plans future strategy

    International Nuclear Information System (INIS)

    The future strategy of Saudi Arabia with respect to its oil production capacity is discussed. A major uncertainty affecting planning is the prospect of an Iraqi return to the market as and when Saddam Hussein falls or he manages to comply fully with all the UN resolutions and sanctions are lifted. It is believed that Iraq could at very short notice be capable of exporting 2mb/d of crude rising to 2.5 mb/d within a few months. This is 10% of OPEC's physically traded crude. Also taken seriously are Baghdad's assertions that Iraq will have a production capacity of about 6mb/d by the year 2000. Saudi officials are concerned that OPEC is not ready to tackle the impact of an Iraqi return to the market at a time when some OPEC members are producing above quota anyway. The most likely outcome is thought to be that OPEC would simply raise their nominal production ceiling. Against this background, Saudi Arabia has embarked on the exploitation of the gigantic oil reserves of the Shaybah field. This development offers the kingdom an ability, on the one hand, to increase its earnings while remaining within its OPEC quota and, on the other hand, to increase output substantially should it ever appear that its best interests are served by not adhering to quotas.

  8. Cholera outbreak in Senegal in 2005: was climate a factor?

    Guillaume Constantin de Magny

    Full Text Available Cholera is an acute diarrheal illness caused by Vibrio cholerae and occurs as widespread epidemics in Africa. In 2005, there were 31,719 cholera cases, with 458 deaths in the Republic of Senegal. We retrospectively investigated the climate origin of the devastating floods in mid-August 2005, in the Dakar Region of Senegal and the subsequent outbreak of cholera along with the pattern of cholera outbreaks in three other regions of that country. We compared rainfall patterns between 2002 and 2005 and the relationship between the sea surface temperature (SST gradient in the tropical Atlantic Ocean and precipitation over Senegal for 2005. Results showed a specific pattern of rainfall throughout the Dakar region during August, 2005, and the associated rainfall anomaly coincided with an exacerbation of the cholera epidemic. Comparison of rainfall and epidemiological patterns revealed that the temporal dynamics of precipitation, which was abrupt and heavy, was presumably the determining factor. Analysis of the SST gradient showed that the Atlantic Ocean SST variability in 2005 differed from that of 2002 to 2004, a result of a prominent Atlantic meridional mode. The influence of this intense precipitation on cholera transmission over a densely populated and crowded region was detectable for both Dakar and Thiès, Senegal. Thus, high resolution rainfall forecasts at subseasonal time scales should provide a way forward for an early warning system in Africa for cholera and, thereby, trigger epidemic preparedness. Clearly, attention must be paid to both natural and human induced environmental factors to devise appropriate action to prevent cholera and other waterborne disease epidemics in the region.

    2016-06-01

    Full Text Available Growing Jatropha curcas for energy applications in has been established through several initiatives in Senegal. The government of Senegal launched the National Jatropha Programme (NJP in 2006 with the goal of planting 321,000 ha of Jatropha curcas, with an average of 1000 hectares (ha in each rural locality. This paper reviews existing policies with relevance to Jatropha curcas L production in Senegal. It assesses the NJP implementation, identifies potential gaps and provides recommendations with regards to planning, institutional management, regulation, and implementation. The potential of Jatropha and other biodiesel crop options, based on findings from an agro-environmental mapping exercise have been shown. Findings show that prior policies in agricultural and energy sectors had been instrumental in developing the NJP. It highlights significant challenges in the value chain, the implementation of NJP and on the importance of using empirical assessment of evidence to inform on the biodiesel crop type compared to a focus on only one crop, Jatropha. Agro-environmental mapping was identified as useful technique prior to biodiesel cultivation. The work reported here indicates Jatropha having the largest suitability of land areas equating to almost thirty times (30 the original estimations in the NJP followed by Pongamia and sunflower with 6,796,000 ha and 5,298,900 ha respectively. Recommendations are provided suggesting, scientifically sound analysis from agro-environmental mapping to inform on the suitability of areas for Jatropha cultivation and on environmentally, socially and culturally sensitive areas. Policy options have been suggested for environmentally benigned sustained biodiesel activities in Senegal.

    During the past decade, the Kingdom of Saudi Arabia has undergone rapid economic growth and development. This expansion stems from the increase in the Kingdom's production of petroleum--oil being the source of most of the country's exports, foreign exchange, and government revenues. However, despite this growth, Saudi Arabia is one of the top foodstuff importers among developing countries. It has been estimated that the value of Saudi agriculture imports in 1981 increased about 33 percent to ...

  4. Overview of mutation breeding in Sudan

    International Nuclear Information System (INIS)

    Mutation breeding has effectively started about twenty years ago with the implementation of the first technical cooperation (TC) project of the IAEA in Sudan. This presentation highlights achievements and prospect of this collaboration. The first TC project (SUD 5/023) was confined to cotton and sugarcane while in the following projects (SUD 5/028 and SUD 5/030) other crops such as sesame, banana, tomato, groundnuts and cereals were included. The mutation program also benefited from the regional projects (RAF5/50 and RAF5/56). Plant breeders involved in mutation breeding increased from less than five in the first project to over 15 in the current one. A banana mutant cultivar (ALBEELY) was released in the year 2003. Albeely excelled the yield of the existing cultivars by 40% and has better crop stand and fruit quality. Albeely is becoming popular and widely preferred by farmers. A drought tolerant ground nut mutant (Barberton-B-30-3) and a number of promising mutants resistant for tomato yellow leaf curl virus (TYLCV) are being evaluated in multi-location trails in preparation for their commercial release. Cotton germplasm has been enrich with a number of useful mutants carrying resistance for bacterial blight and fusarium wilt disease in addition to mutants for weak fiber attachments and high ginning out turn and lint percentage. These mutants are being used in the breeding program and promising lines are under field evaluation for release. The mutation breeding program is strengthened by installing irradiator and establishing tissue culture and molecular laboratories. It is evident that the TC program of the IAEA has contributed significantly to the establishment and sustainability of mutation breeding and related biotechnologies in Sudan. The program is progressively expanding and a number of outstanding cultivars were released or in the pipeline. Intensive work is under way to generated production package for these mutants and set a demonstration plot program

    1995-12-01

    Full Text Available Domestic factors played a significant role in Sudan's external debt crisis which emerged in the early 1980's. Personal rule and related political survival considerations undermined on-going economic adjustment programmes and prompted heavy external borrowing. Borrowing from abroad went unchecked because of the absence of an effective debt management system. It was also fuelled by economic corruption and the decline of cotton, Sudan's principal export crop. The absence of an effective debt management mechanism and economic corruption were a product of the lack of political and fiscal accountability in the context of personal rule.

    Background The classification of HIV-1 strains in subtypes and Circulating Recombinant Forms (CRFs) has helped in tracking the course of the HIV pandemic. In Senegal, which is located at the tip of West Africa, CRF02_AG predominates in the general population and Female Sex Workers (FSWs). In contrast, 40% of Men having Sex with Men (MSM) in Senegal are infected with subtype C. In this study we analyzed the geographical origins and introduction dates of HIV-1 C in Senegal in order to better understand the evolutionary history of this subtype, which predominates today in the MSM population Methodology/Principal Findings We used a combination of phylogenetic analyses and a Bayesian coalescent-based approach, to study the phylogenetic relationships in pol of 56 subtype C isolates from Senegal with 3,025 subtype C strains that were sampled worldwide. Our analysis shows a significantly well supported cluster which contains all subtype C strains that circulate among MSM in Senegal. The MSM cluster and other strains from Senegal are widely dispersed among the different subclusters of African HIV-1 C strains, suggesting multiple introductions of subtype C in Senegal from many different southern and east African countries. More detailed analyses show that HIV-1 C strains from MSM are more closely related to those from southern Africa. The estimated date of the MRCA of subtype C in the MSM population in Senegal is estimated to be in the early 80's. Conclusions/Significance Our evolutionary reconstructions suggest that multiple subtype C viruses with a common ancestor originating in the early 1970s entered Senegal. There was only one efficient spread in the MSM population, which most likely resulted from a single introduction, underlining the importance of high-risk behavior in spread of viruses. PMID:22470456

    2009-07-01

    The establishment of a Shi`i Islamic network in Senegal is one alternative to following the country's dominant Sufi orders. I examine Senegalese conversion narratives and the central role played by the Iranian Revolution, contextualizing life stories (trans)nationally in Senegal's political economy and global networks with Iran and Lebanon. Converts localize foreign religious ideologies into a 'national' Islam through the discourse that Shi`i education can bring peace and economic development to Senegal. Senegalese Shi`a perceive that proselytizing, media technologies, and Muslim networking can lead to social, cultural and perhaps even political change through translating the Iranian Revolution into a non-violent reform movement.

    Full Text Available The main objective of this research is to study the role of energy consumption in economic growth in Saudi Arabia over the period of 1971–2012 using the autoregressive distributed lag (ARDL cointegration procedure, and based on neoclassical growth, endogenous growth, and ecological-economics viewpoints. Our empirical results show the existence of a cointegrating relationship between the different variables investigated. In addition, all the inputs (conventional and non-conventional Granger cause economic growth in both the short and long runs. Our findings confirm the energy-led growth hypothesis in the case of Saudi Arabia. Hence, energy conservation policies may deteriorate economic growth in Saudi Arabia if they are not followed by measures that improve energy efficiency, energy saving technologies and encourage the investment and use of renewable energy sources such as solar and wind energies that can participate in the attenuation of climate changes.

    Full Text Available Renal involvement determines the prognosis of systemic lupus erythematosus (SLE. The aims of this study were to assess the clinical, laboratory and therapeutic aspects of lupus nephritis (LN in Senegal in order to improve its management. We included all patients presenting with SLE followed-up in the Internal Medicine and Dermatology Clinics of the Aristide Le Dantec University Teaching Hospital of Dakar, from January 1993 to December 2002. Patients with SLE without evidence of LN (defined by proteinuria more than 0.5 g/24 hours and/or hematuria were excluded. A total of 74 patients with a diagnosis of SLE were studied, 42 of whom (56.75% had features of LN. Their mean age was 29.6 years and male-female ratio was 0.13. The nephrotic syndrome was seen in 45.23% of the cases and renal insufficiency in 37.71%. Renal biopsy was performed in 52.38% of the cases, which showed predominantly WHO classes IV and V lesions. The main treatment modality employed was corticoste-roids, while immunosuppressive drugs in addition were used in 35.71% of the patients. The short-term prognosis was favorable but in the middle-term, many patients were lost to follow-up. We conclude that early diagnosis by systematic urine screening, good patient information, percutaneous renal biopsy and use of appropriate immunosuppressive therapy will help improving the prognosis of LN in Senegal.

  16. Licensing and inspection of industrial radiography in Sudan

    International Nuclear Information System (INIS)

    The use of radioisotopes in Sudan started in 1965 in the medical field, and gradually expanded in agriculture, animal research, hydrology and recently industry. During the last 4 years oil industry in Sudan became one of the biggest activity. Almost 11 foreign companies are involved in oil industry including exploration, establishment of refineries and construction of pipelines. Sudan's pipeline is the longest in Africa, about 1600 Km. The estimated number of radiation workers in these Companies are 100, some of them are locals. The country Regulatory Authority is Sudan Atomic Energy Commission (SAEC). The Commission provides personal monitoring services to all radiation workers in the country. Only about 20% of the radiation workers in these companies are under monitoring services. The total number of registered sources about 500. Number of sources used in the industrial applications of about 40% of the inventory. SAEC has difficulties in controlling the industrial radiography in the country. These difficulties can be summarized as follows: a. Difficulties in pertaining information provided by the Companies, which include: not all sources used by companies are licensed and registered; not all workers are under personal monitoring services; no notification system available by the companies to the regulatory authority in case of accidents; not enough information available by the companies to SAEC regarding the radiation work done by them (transparency). b. Poor communications with the companies. c. Resources constrains: Not enough resources for inspection missions (means of transportation). (author)

  1. Current situation of Peste des petits ruminants (PPR) in Sudan

    International Nuclear Information System (INIS)

    The current situation of Peste des petits ruminants (PPR) in Sudan was investigated. A total of 1198 serum samples were collected from camels (392), sheep (500) and goats (306) at different areas in Sudan (Khartoum, Gezira, River Nile, Kordofan, White Nile, Gedarif, Kassala, Blue Nile, Tambool, Port Sudan, Halfa ElGadida). A total of 61 tissue samples were also collected from various PPR suspected outbreaks in sheep and goats in 2008. Collected sera were examined for PPR antibodies using cELISA. Collected tissue samples were tested for PPR antigen using IcELISA. Both tests were done according to the product manual of the kits manufacturer (CIRAD EMVT, Montpellier, France 2005), distributed by BDSL. A total of 336 sheep, 170 goat samples were found to be positive. Only one camel serum was positive. The PPR antigen was detected in 26 out of 61 samples. The PPR antibody and antigen detection results are summarized. The results showed that PPR exists in Sudan in different localities. The overall detected seroprevalence of PPR was 62.8%, which is higher than that previously reported (50%) in Sudan. Sheep were noticed to have higher percentage of seropositivity than goats (67.7 vs. 55.6%, respectively) in agreement with the results of Intisar et al. The highest seroprevalence of PPR (95%) was noticed in Kassala samples from Eastern Sudan followed by 83.3% in Blue Nile region (Eastern to South Sudan) and Gedarif (73.8%). PPR antibodies were found to be prevalent in sheep samples in Khartoum State (93.8%), then Gedarif (88.6%), Blue Nile (83.6%) and Gezira (73.6%). PPR antigen detection was carried out using IcELISA; the overall detected samples were 42.6% of 61 tested samples. Highest prevalence of the disease was noticed in River Nile, Gedarif and Kassala (100%) however only one sample was tested from each locality; Samples collected from Kordofan area showed 63.6% positivity while those of Gezira State were 27%.

    Full Text Available BACKGROUND: Despite historical evidence of blinding trachoma, there have been no widespread contemporary surveys of trachoma prevalence in the northern states of Sudan. We aimed to conduct district-level surveys in this vast region in order to map the extent of the problem and estimate the need for trachoma control interventions to eliminate blinding trachoma. METHODS AND FINDINGS: Separate, population based cross-sectional surveys were conducted in 88 localities (districts in 12 northern states of Sudan between 2006 and 2010. Two-stage cluster random sampling with probability proportional to size was used to select the sample. Trachoma grading was done using the WHO simplified grading system. Key prevalence indicators were trachomatous inflammation-follicular (TF in children aged 1-9 years and trachomatous trichiasis (TT in adults aged 15 years and above. The sample comprised 1,260 clusters from which 25,624 households were surveyed. A total of 106,697 participants (81.6% response rate were examined for trachoma signs. TF prevalence was above 10% in three districts and between 5% and 9% in 11 districts. TT prevalence among adults was above 1% in 20 districts (which included the three districts with TF prevalence >10%. The overall number of people with TT in the population was estimated to be 31,072 (lower and upper bounds = 26,125-36,955. CONCLUSION: Trachoma mapping is complete in the northern states of Sudan except for the Darfur States. The survey findings will facilitate programme planning and inform deployment of resources for elimination of trachoma from the northern states of Sudan by 2015, in accordance with the Sudan Federal Ministry of Health (FMOH objectives.

  5. Rapid evolution of water resources in the Senegal delta

    In recent decades major water developments have led to an agricultural transformation of the Senegal delta both in Senegal and Mauritania. This otherwise, semi-arid region of the Sahel band now has an abundant supply of freshwater all year round mostly used for irrigation and urban water supply, including for the capital cities of the two countries. Archives from the Landsat satellites and in-situ hydrographs were used in this paper to retrace and analyse the hydrological changes that have taken place in the region since the middle of the 20th century. The satellite archives indicate that the area covered by irrigation increased by one order of magnitude from 73 km2 in 1973 to ~ 770 km2 in 2010. The observed hydrological changes are complex, multi-faceted and often of great magnitude. If the water cycle was representative of natural conditions in the early 1980s, it is now representative of a heavily modified system controlled and impacted by human activities. The first hydraulic infrastructure was installed in 1947 to enable the Lake of Guiers to become the main water supply for Dakar. Two large dams were built on the Senegal River in the mid-1980s that modified the hydrological regime of the river by 1) preventing seawater intrusion, 2) raising the stage of the river and of Lake of Guiers and 3) moderating floods. Another recent hydrological change in the delta was the opening of river mouth in 2003, which has led to a reduction of the average water level while increasing the semi-diurnal tidal wave between the river mouth and Diama. Each phase of these river regime changes and each step of the irrigation expansion are expressed in localised changes in the physical groundwater system. Increasingly, the retroaction from the shallow aquifer systems is observed as a rise of the saline water table. This poses a threat to the environmental and agricultural value of the region, and the salinization of the soils. Mitigating actions for this threat are currently being

  6. Agricultural water and energy use in the Senegal River Valley

    Masiyandima, M. C.; Sow, A.

    2015-12-01

    Assessment of the productivity of irrigation water is important measuring the performance of irrigation schemes especially in water scarce areas. Equally important for performance is the energy cost of providing water for irrigation. Sahel irrigation schemes are dependent on pumping water from rivers into a network of gravity operated channels. In the Senegal River valley in Senegal the cost of pumping water and for irrigation has been estimated to be 20-25% of total rice production costs. Irrigation schemes in the valley are characterized by low water productivity. We analysed rice production, irrigation water use and energy use for supplying irrigation water at Pont Gendarme, Ndiawar and Ngallenka MCA irrigation schemes in the Senegal River valley. For the 2013 rainfall season the mean yield ranged between 6 and 8t ha-1. Dry season yield ranged between 1.7 and 6.8t ha-1. Energy use for irrigation in the Ndiawar irrigation scheme was 8kg MJ-1 and 6.4kg MJ-1 in the 2013 and 2014 rainfall seasons respectively. In 2014 (rainfall season) energy productivity of irrigation water was 8.5, 8.0 and 16.4 kg MJ-1 at Ngallenka MCA, Ndiawar and Pont Gendarme respectively. Dry season (2014) energy productivity at Ndiawar and Pont Gendarme was 3.4 and 11.2kg MJ-1 respectively. Productivity of irrigation water was similar for all schemes (0.37kg m-3 at Pont Gendarme, 0.42kg m-3 at Ngallenka MCA, and 0.41kg m-3 Ndiawar). Energy use for the supply of irrigation water in the rainfall season ranged from 403 to 1,002MJ ha-1. Dry season irrigation energy use was 589MJ ha-1 Pont Gendarme and 331MJ ha-1 at Ndiawar. Reducing water use in these schemes through better water management will result in lower production costs and increased margins for the farmers. The observations from 2013 - 2014 highlight the importance of using both water and energy productivity to assess performance of irrigation schemes.

    This article discusses return migration and evaluates the government's role in developing the potential of return migrants in Senegal. The three sections give a profile of return migrants, Senegal's pertinent official policies, and recommendations for action to improve reintegration into the local context. Although capital and goods flow freely in the global marketplace, globally, the flows of workers are constrained by restrictive immigration policies of host countries. Senegal and France have agreed to cooperate by containing migration flows and promoting migrants as agents of development, who can bring needed skills back to the countries of origin. Senegal has out-migration of about 50% of the poorest households. Receiving countries are scattered throughout the world. France receives about 105,000 and Cote d'Ivoire receives about 150,000. Migrants may be registered or unregistered. Migrants maintain close ties in their homeland and send remittances.

    2015-03-01

    Full Text Available This study was undertaken between 2008 and 2010 to assess annual gum production potential per tree for different varieties of Acacia senegal (var. kerensis; var. senegal and var. leiorhachis growing naturally in Kenyan drylands. Eight sample plots of 1.0 hectare were established, one at each site. All trees in each sample plot were measured for basal diameter and classified into three diameter size classes (3.0-6.0 cm, 6.1-9.0 cm and > 9.0 cm. Ten trees from each diameter class were selected for tapping while another ten trees left untapped as control. Results indicate that gum yield by different varieties of A. senegal varied with basal diameter (BD size classes. A. senegal var. senegal yielded high quantities of gum compared to the other two varieties. Tapping increased yield by 47.1%, 91.8% and 85.7% for trees in diameter classes 3.0-6.0cm, 6.1-9.0cm and >9.0 cm respectively. On average, tapping increased gum production by 74.9%. These results can be used for estimating gum yield potential of naturally growing A. senegal in relation to the variety, tree size and site conditions. Besides, the upshot of these findings offers new management guidelines that can improve gum production through tapping for the economic, social and environmental benefits of local communities living in the drylands of Kenya.

  11. Career profile of dentists in Saudi Arabia

    International Nuclear Information System (INIS)

    The aims of the present survey were to determine whether differences existed between male and female dentists in Saudi Arabia in career development, positions occupied within their employment, and to analyze the effect of different variables on their career development in some of the provinces in Saudi Arabia. A self-conducted questionnaire was distributed among male and female dentists, general practitioners as well as specialists, working at several governmental hospitals in Saudi Arabia. The questionnaires consisted of 40 questions in the format of multiple choices and yes/no answer. Data were analyzed by gender with the significant difference level set at (P < 0.05). The response rate was 40.8% of which 51.9% were females and 48.1% males with 70% of them below 45 years of age. No significant difference was found between males and females in having higher education or additional degrees. The specialty that was highly reported among females was pedodontics and in males, orthodontics. Males were more likely to hold authorized administrative positions (63%), while females held administrative positions which were internally arranged by their departments (57%). Eighty-three percent of female respondents thought that there was favouritism towards males in appointment to administrative positions, while only 5.5% of male respondents reported that there was favouritism to females in occupying the same positions. There was no significant difference between male and female dentists in Saudi Arabia with respect to job opportunities, working hours and relationships with their colleagues. In addition, there is evidence of an intensifying determination of female dentists in Saudi Arabia, to pursue their chosen career while coping with the diverse demands of being a professional, a wife and mother.

    We successfully cultured 36 Plasmodium falciparum isolates from blood samples of 44 malaria patients admitted to the Hôpital Principal de Dakar (Dakar, Senegal) during August-December 2014. The prevalence of isolates with in vitro reduced susceptibility was 30.6% for monodesethylamodiaquine, 52.8% for chloroquine, 44.1% for mefloquine, 16.7% for doxycycline, 11.8% for piperaquine, 8.3% for artesunate, 5.9% for pyronaridine, 2.8% for quinine and dihydroartemisinin, and 0.0% for lumefantrine. The prevalence of isolates with reduced in vitro susceptibility to the artemisinin-based combination therapy partner monodesethylamodiaquine increased from 5.6% in 2013 to 30.6% in 2014. Because of the increased prevalence of P. falciparum parasites with impaired in vitro susceptibility to monodesethylamodiaquine, the implementation of in vitro and in vivo surveillance of all artemisinin-based combination therapy partners is warranted.

  17. Nuclear cardiology in Senegal: a luxury or a need?

    International Nuclear Information System (INIS)

    Aim: to sensitize at the same time experts and public authorities on the interest of the establishment of nuclear cardiology in Senegal. Material and method: the radioimmunoassay of micro-albuminuria, early marker of cardiovascular morbid-mortality was carried out in the nuclear medicine department of Dakar on a population of 100 diabetic patients (74 of type 1 and 26 of type 2) presenting one or more traditional cardiovascular risk factors. Out of these patients, 39% had abnormal rest ECG, asymptomatic in half of the cases. Results: prevalence of micro-albuminuria is high (24%). There is no significant difference in distribution between type I and type 2. Micro-albuminuria > 30 mg/24 h exists in 16,3% of patients with lipid abnormalities (ratio: total cholesterol/HDL cholesterol > 5), 30% of obese, 75% of hypertensive patients and 43,6% of patients with abnormal rest ECG, who would benefit from myocardial perfusion imaging (MPI): about 17% of patients involved in this study. No or weak correlation is found between micro-albuminuria and traditional risk factors. Conclusion: From these results and available epidemiological data in 2005, the estimate of the requirements in nuclear cardiology for the Senegalese diabetic population, indicates that 3740 patients should have benefited that year from it. Considering that this figure underestimates the real needs, taking into account the needs brought back to a population of 10 million inhabitants and the expect expansion of the diabetic disease, it appears justified to include the nuclear cardiology in the national programmes of prevention of the public health in Senegal.

    Mathieu, Gueye; Meissa, Diouf

    2007-01-01

    Six administrative regions of Senegal were investigated. Forty species of vegetable leaves which are traditionally consumed in Senegal have been inventoried. All species are members of twenty-one families the most numerous of which are Amaranthaceae Juss., Malvaceae Juss., Moraceae Link., the Papilionaceae Giseke and Tiliaceae Juss. The species are subdivided into three groups: cultivated leafy vegetables, plants gathered annually, perennial sub-ligneous and ligneous species. The gathered species represent 67.5% of the inventory, 40.7% of which is ligneous. Cultivated species account for 32.5% of the inventory. The species are consumed for their medicinal properties, nutritive value and eating habits linked to specific ethnic traditions. During the drought years, with the scarcity of main food (millet, mays) consumption of leafy vegetables is high. All species reported except Sesuvium portulacastrum L. are consumed like vegetable herbs. The species of Hibiscus are eaten in spinach and condiment form while Sesuvium portulacastrum L is cooked in salad. Of the forty species examined, eleven are widely consumed. Within the entire study area, Hibiscus sabdariffa predominates among species consumed, followed by Moringa oleifera Lam. and Senna obtusifolia Link. A high consumption level of some species like amarante, Corchorus tridens L., Corchorus aestuans L., Leptadenia hastata Decne. and Vigna unguiculata (L.) Walp is confined to certain areas. In addition to their consumption as vegetables, the medicinal uses of 57.5% of these is of primary importance. The most commonly exploited parts are, respectively, leaf (40%), roots (20%), and bark (13.3%). Among the numerous pathologies treated, abscess, constipation, and rheumatism are predominant followed by aphrodisiac uses. The Amaranthus spp. L., Leptadenia hastata Decne., Senna obtusifolia Link., Adansonia digitata L. and Tamarindus indica L. are species with multiple medicinal uses. PMID:20161914

  19. Correlation between NDVI and the annual groundnut yield in Senegal

    A key strategy to assert and minimize risk in agriculture is to gather information about the factors that may affect the production. That is why remote sensing measurements have become a fundamental tool in this area. Between all the existing measurements, the Normalized Difference Vegetation Index (NDVI) is one of the most useful. The NDVI, which is computed using satellite images, takes into account the physicochemical mechanism of the photosynthesis in order to quantify the photosynthetic activity of a an area. A natural question that arises from the risk and hazard management point of view is if this index can help us estimate or even forecast the yield of a given harvest. Intuitively, this should be possible if a correlation between NDVI and yield is found. We have focused our study in the country of Senegal, where more than 70% of the work force is employed in the agricultural sector. Since Senegal is also one of the most important peanut oil producer and exporter, the crop we have chosen for this research is the peanut. The economic relevance of this product guarantees that a significant fraction of the soil will be used for this crop. We have worked with NDVI data computed from satellite images taken with the MODIS instrument of the Terra satellite launched by NASA on 1999. In order to explore the correlations with agricultural yield, we have also retrieved production data from the Food and Agriculture Organization (FAO) of the United Nations. The results we have obtained suggest that a linear correlation between NDVI and yield do exist; moreover, this correlation can be enhanced if, instead of yearly averages of NDVI, the NDVI corresponding to a smaller time period -which lies within the growing season - is taken.

  20. Water management in the Senegal River Delta: a continuing uncertainty

    M. Mietton

    2007-11-01

    Full Text Available Water management is the driving force behind the productivity of the ecosystems of the Senegal River Estuary and floodplains. It is dependent on human decision-making, but has been separated from the River's flooding since the building of the Diama Dam. The current objectives of the Office de Mise en Valeur du fleuve Sénégal (OMVS: Senegal River Development Agency are mainly turned towards the development of irrigated agriculture on the former floodplains and since 2002 the production of hydroelectric power at Manantali. In October 2003, a four-metre-wide runoff canal, which quickly widened into a breach several hundred metres across, was dug in the Barbary Spit area to protect the city of Saint-Louis from heavy flooding. The hydraulic quality of the area downstream from the dam has improved to the extent that there is no longer any flooding there, but as the management of the dams concerns only the section of the river between Manantali and Diama, a certain amount of flood risk probably still persists. The intrusion of seawater into the estuary is also threatening ecosystems and fresh water supplies, and abruptly altering agricultural practices such as fruit and vegetable growing in the Gandiolais district. When added to the tentative efforts to coordinate the management of the two dams, with no management objective downstream from Diama, such permanent modifications impose serious constraints on the managers and residents of the lower delta. This paper presents an overview of the constraints and uncertainties at different levels and scales. This wholly human-wrought environment can be considered as a learning experience, where a large number of variables need to be monitored closely and an ongoing process of participatory analysis should be backed up by multidisciplinary research.

  1. Mermithid nematodes found in adult Anopheles from southeastern Senegal

    2012-06-01

    Full Text Available Abstract Background Over two dozen mermithid nematodes have been described parasitizing mosquitoes worldwide, however, only two species were found in Africa. Mermithid nematodes kill their mosquito host upon emergence, which suggests that they could be developed as biological control agents of mosquitoes. Both Romanomermis culicivorax and Romanomermis iyengari have been reared for mass release to control numerous Anopheles species vector populations, and in one instance this may have led to reduced malaria prevalence in a human population. Methods Anopheles mosquitoes were collected during a malaria study in southeastern Senegal. Two different adult blood fed mosquitoes had a single mermithid nematode emerge from their anus while they were being held post-capture. Primers from the 18 S rDNA were developed to sequence nematode DNA and screen mosquitoes for mermithid DNA. 18 S rDNA from the Senegalese mermithid and other mermithid entries in GenBank were used to create a Maximum Parsimony tree of the Mermithidae family. Results The mermithid was present in 1.8% (10/551 of the sampled adult Anopheles species in our study area. The mermithid was found in An. gambiae s.s., An. funestus, and An. rufipes from the villages of Ndebou, Boundoucondi, and Damboucoye. Maximum parsimony analysis confirmed that the nematode parasites found in Anopheles were indeed mermithid parasites, and of the mermithid sequences available in GenBank, they are most closely related to Strelkovimermis spiculatus. Conclusions To our knowledge, this is the first report of mermithids from adult Anopheles mosquitoes in Senegal. The mermithid appears to infect Anopheles mosquitoes that develop in diverse larval habitats. Although maximum parsimony analysis determined the mermithid was closely related to Strelkovimermis spiculatus, several characteristics of the mermithid were more similar to the Empidomermis genus. Future mermithid isolations will hopefully allow: formal

  2. Zika virus emergence in mosquitoes in southeastern Senegal, 2011.

    Directory of Open Access Journals (Sweden)

    Diawo Diallo

    Full Text Available Zika virus (ZIKV; genus Flavivirus, family Flaviviridae is maintained in a zoonotic cycle between arboreal Aedes spp. mosquitoes and nonhuman primates in African and Asian forests. Spillover into humans has been documented in both regions and the virus is currently responsible for a large outbreak in French Polynesia. ZIKV amplifications are frequent in southeastern Senegal but little is known about their seasonal and spatial dynamics. The aim of this paper is to describe the spatio-temporal patterns of the 2011 ZIKV amplification in southeastern Senegal.Mosquitoes were collected monthly from April to December 2011 except during July. Each evening from 18:00 to 21:00 hrs landing collections were performed by teams of 3 persons working simultaneously in forest (canopy and ground, savannah, agriculture, village (indoor and outdoor and barren land cover sites. Mosquitoes were tested for virus infection by virus isolation and RT-PCR. ZIKV was detected in 31 of the 1,700 mosquito pools (11,247 mosquitoes tested: Ae. furcifer (5, Ae. luteocephalus (5, Ae. africanus (5, Ae. vittatus (3, Ae. taylori, Ae. dalzieli, Ae. hirsutus and Ae. metallicus (2 each and Ae. aegypti, Ae. unilinaetus, Ma. uniformis, Cx. perfuscus and An. coustani (1 pool each collected in June (3, September (10, October (11, November (6 and December (1. ZIKV was detected from mosquitoes collected in all land cover classes except indoor locations within villages. The virus was detected in only one of the ten villages investigated.This ZIKV amplification was widespread in the Kédougou area, involved several mosquito species as probable vectors, and encompassed all investigated land cover classes except indoor locations within villages. Aedes furcifer males and Aedes vittatus were found infected within a village, thus these species are probably involved in the transmission of Zika virus to humans in this environment.

    The progress of women in physics education in the last five years was surveyed in the six top universities in Sudan. The data reveal great increases in the number of females studying undergraduate physics. Most were studying experimental physics rather than theoretical physics, especially the laser and electronics fields. It appears undergraduate laboratory experiments are an important factor in attracting women to physics. Our survey found that girls are encouraged to study physics at the high school level. However, the data also showed that the fewer tendencies to study physics among the women after high school are due to the limited job opportunities and low income of teachers. Postgraduate physics study is handicapped by lack of institutions, financial constraints, and lack of qualified advisors. Improvement of education systems and new ways of teaching will have great influences on attracting women to physics in Sudan.

  6. Prevalence of Trypanosoma vivax in cattle in central Sudan

    International Nuclear Information System (INIS)

    The study was conducted to validate an antibody-detection ELISA test (Ab-ELISA) using pre-coated ELISA plates with crude antigen preparation of Trypanosoma vivax and to study the prevalence of T. vivax infection in central Sudan. A total of 704 blood samples were collected from cattle in central Sudan, a known endemic area of T. vivax infection. Additionally, 74 blood samples were collected from northern Sudan (Atbra town), an area presumed to be T. vivax-free. Sera were collected during the period September 1998 to May 1999 during three different seasons (summer, autumn and winter). Under the existing laboratory conditions, the test showed a clear distinction between different controls, i.e. strong positive control (C++), weak positive control (C+), negative control (C-) and the conjugate control (Cc). A percent positivity of 25% was taken as a cut-off value to determine the positivity or negativity of the test. The acceptable optical density range of strong positive control (C++) was 0.65-1.22. Lower and upper percent positivity limits for different controls were also determined. The study showed that T. vivax is endemic in central Sudan with 1.4% prevalence based on parasitological examination and 29.26% on Ab-ELISA. The infection rate was significantly higher during the autumn and winter than in summer. Young cattle showed significantly lower infection rates than adults as indicated by both the parasitological and the Ab-ELISA test. In relation to husbandry practice, migratory cattle showed significantly higher rates of prevalence than resident cattle. There was no significant difference in average packed red cell volume (PCV) values between ELISA positive and ELISA negative animals. Calves of less than one year of age showed significantly lower PCV values when belonging to migratory herds than to resident herds. (author)

    2011-11-01

    Full Text Available Among arid zone tree species, Acacia senegal and Prosopis cineraria are the most important dryland resources of Western Rajasthan desert ecosystem. Due to ecological, biological and molecular similarities, they are often studied together. The climatic conditions in this region restrict the build-up of soil organic matter and soils are generally deficient in nitrogen. Studies were carried out to isolate and molecularly characterize the diverse group of plant growth promoting rhizobacteria from root nodules of native A. senegal and P. cineraria and their effect on seed germination and seedling traits in two genotypes of A. senegal. The direct sequencing of 16S rDNA region resulted in molecular identification of plant growth promoting rhizobacteria as Bacillus licheniformis, Sinorhizobium saheli isolated from root nodules of A. senegal and S. kostiense and S. saheli isolated from root nodules of P. cineraria. The partial sequences of 16S rDNA were assigned Gen accession numbers HQ738496, HQ738499, HQ738506 and HQ738508. Scarification treatment with sulphuric acid (98% for 15 minutes was able to break the exogenous seed dormancy and enhanced germination percentage in control treatment to 90% and 92.5% in A. senegal in genotypes CAZRI 113AS and CAZRI 35AS, respectively. The treatments with Bacillus licheniformis or S. kostiense, either inoculated individually or as coinoculants, had positive effect on phenotypic traits of germination. Two A. senegal genotypes exhibited significant differences with regard to all the phenotypic traits. On the other hand, treatments with S. saheli isolated from either A. senegal or P. cineraria had negative effects on germination and related phenotypic traits. Values of the coeffivient of determination (R2 over 80% for root length versus shoot length, root/shoot ratio and seedling weight respectively validate that the observed attributes are inter-dependable and linear progression trend can be predicted.

Corresponding Nd model ages (tDM) cluster around 0.84 Ga for the mostly volcanic-derived Blue Nile, Atbara, and Main Nile muds, range 1.2 - 1.5 Ga for tributaries draining Ethiopian basement rocks, and reach as high as 2.4 Ga for the Bahr Ez Zeraf. The different Nd isotopic signal between mud and sand samples is closely controlled by mineralogical composition, Nd and other REE being chiefly contributed by ultradense minerals (e.g., monazite), and consequently concentrated in the finest size fractions of each sample (Garzanti et al., 2008).

  18. Core inflation indicators for Saudi Arabia

    Directory of Open Access Journals (Sweden)

    Alkhareif Ryadh M.

    2015-01-01

    Full Text Available This paper constructs and analyzes core inflation indicators for Saudi Arabia for the period of March 2012 to May 2014 using two alternative approaches: the exclusion method (ex food and housing/rent and the statistical method. The findings of the analysis suggest that the ex food and housing/ rent inflation is more volatile than the overall CPI inflation over the sample period. In contrast, the statistical core inflation is relatively more stable and less volatile. Moreover, the ex food and housing/rent inflation is only weakly correlated with headline inflation, whereas the statistical core inflation exhibits a stronger correlation. This combination of lower volatility and higher correlation with headline inflation makes the statistical method a much better choice for policymakers. From a monetary policy standpoint, using a bundle of core inflation measures, including both properly constructed exclusion and statistical methods, is more desirable, especially when variation across measures is widespread, as is the case in Saudi Arabia.

    Full Text Available The expansion of power generation in Saudi Arabia is essential in order to meet the expected growth of its electricity demand. Due to the availability of high solar irradiation, vast rainless area and longtime sun light, Saudi Arabia is one of the most suitable countries to utilize solar energy resources in greater extend. Kingdom has planned to increase the production of solar power in order to meet a considerable share of country’s future energy demand. Numerous installation and research works are going on nowadays in the kingdom in order to attain its targets of solar power capacity in the coming years. Hence latest updates of country’s solar industry are essential for further research and R&D works in this field. Saudi Arabia’s current status and future possibility of solar industry are discussed in this paper.

  20. Peaceful nuclear energy to Saudi Arabia

    International Nuclear Information System (INIS)

    The argument for and against the application of peaceful nuclear energy in Saudi Arabia is discussed in terms of the country's industrial development and power requirement for electricity and desalination. The discussion leads to the conclusion that due to its large oil reserve, Saudi Arabia may tolerate a considerate approach to nuclear energy up to the year 2000. Beyond this date, nuclear energy should be used in order to achieve the desired industrial maturity in the country. The introduction of nuclear energy, however, will be faced with three constraints, namely man power availability, cooling water requirement, and the size of the electrical grid. The period 1980-2000 is thus most suitable for important preparation steps, among which are the adoption of regulatory provisions, establishment of nuclear facilities with necessary equipments, and staff training for regulatory, organizational, and technical activities. The paper outlines a scheme for the initiation steps and efforts to meet these requirements. (orig.)

  3. Implementation of nuclear desalination in Saudi Arabia

    International Nuclear Information System (INIS)

    Most of the Saudi desalination plants are of the multistage flash (MSF) type. These plants are often constructed as a dual purpose installation, producing power and water. MSF plants are considered to be energy intensive, where the energy cost is a major controlling parameter in the overall cost of desalination. Oil price fluctuations affect the cost of desalted water significantly. On the other hand, nuclear power offers price stability in the long term. Nuclear powered desalination provides long term availability of indigenous fuel, as well as long term fuel price stability. It has a minimum environmental impact if compared with other conventional desalination processes. The operational expenses of nuclear desalination are far lower than those of conventional plants. implementation of nuclear desalination in Saudi Arabia is essential where large water requirements exist. The CANDU PHWR is the appropriate type of nuclear reactor for Saudi Arabia. A hybrid reverse osmosis/MSF CANDU PHWR is the candidate system for applying dual purpose nuclear desalination plants in Saudi Arabia. (author)

  4. Low immune response to hepatitis B vaccine among children in Dakar, Senegal.

    Marie-Anne Rey-Cuille

    Full Text Available HBV vaccine was introduced into the Expanded Programme on Immunization (EPI in Senegal and Cameroon in 2005. We conducted a cross-sectional study in both countries to assess the HBV immune protection among children. All consecutive children under 4 years old, hospitalized for any reason between May 2009 and May 2010, with an immunisation card and a complete HBV vaccination, were tested for anti-HBs and anti-HBc. A total of 242 anti-HBc-negative children (128 in Cameroon and 114 in Senegal were considered in the analysis. The prevalence of children with anti-HBs ≥ 10 IU/L was higher in Cameroon with 92% (95% CI: 87%-97% compared to Senegal with 58% (95% CI: 49%-67%, (p<0.001. The response to vaccination in Senegal was lower in 2006-2007 (43% than in 2008-2009 (65%, (p = 0.028. Our results, although not based on a representative sample of Senegalese or Cameroonian child populations, reveal a significant problem in vaccine response in Senegal. This response problem extends well beyond hepatitis B: the same children who have not developed an immune response to the HBV vaccine are also at risk for diphtheria, tetanus, pertussis (DTwP and Haemophilus influenzae type b (Hib. Field biological monitoring should be carried out regularly in resource-poor countries to check quality of the vaccine administered.

  5. Initiative for 100% rural electrification in developing countries: Case study of Senegal

    International Nuclear Information System (INIS)

    Sub-Saharan Africa has the lowest access to electricity in the World. In Senegal, less than 25% of the rural population benefit of electricity service. Solar energy offers an important potential to Senegal with over 3000 h of sunlight a year. This is a real opportunity to generalize the access to electricity. But, the efforts to bridge the gap must be diversified and completed. We approach the problem of rural electrification with a different point of view. Grid expansion and centralized solutions may be adequate for villages with a population organized in high-density of habitations. Small size villages or those with highly dispersed population may need different propositions because of cost. These regions will not be the priority of electrification programs. Furthermore, this rural population is characterized by its low income and saving. Such a conjuncture suggests the opportunity of a service based fees model for access to electricity. On the basis of a fees-for-service model, individual standalone photovoltaic systems may be a more appropriate solution to cover the priority needs of lighting and mobile phones battery charge for telecommunication. We present a pilot project in a village of Senegal to support the model and demonstrate its feasibility. - Highlights: • Rural electrification in developing countries. • Problems of access to electricity in rural areas. • Fees-for-service solution for small villages/highly dispersed population villages. • Situation of Senegal. • Presentation of a pilot project in a small village of Senegal

    Full Text Available Acacia senegal L. (Fabaceae seeds are essential ingredient of “Pachkutta,” a specific Rajasthani traditional food. The present study explored antiatherosclerotic and cardioprotective potential of Acacia senegal seed extract, if any, in hypercholesterolemic diet-induced atherosclerosis in rabbits. Atherosclerosis in rabbits was induced by feeding normal diet supplemented with oral administration of cholesterol (500 mg/kg body weight/day mixed with coconut oil for 15 days. Circulating total cholesterol (TC, HDL-cholesterol (HDL-C, LDL-cholesterol (LDL-C, triglycerides, and VLDL-cholesterol (VLDL-C levels; atherogenic index (AI; cardiac lipid peroxidation (LPO; planimetric studies of aortal wall; and histopathological studies of heart, aorta, kidney, and liver were performed. Apart from reduced atherosclerotic plaques in aorta (6.34±0.72 and increased lumen volume (51.65±3.66, administration with ethanolic extract of Acacia senegal seeds (500 mg/kg/day, p.o. for 45 days to atherosclerotic rabbits significantly lowered serum TC, LDL-C, triglyceride, and VLDL-C levels and atherogenic index as compared to control. Atherogenic diet-induced cardiac LPO and histopathological abnormalities in aorta wall, heart, kidney, and liver were reverted to normalcy by Acacia senegal seed extract administration. The findings of the present study reveal that Acacia senegal seed extract ameliorated diet-induced atherosclerosis and could be considered as lead in the development of novel therapeutics.

    1993-08-01

    Studies of the factors determining migratory patterns in the Senegal River Valley usually stress the importance of economic factors related to colonial domination. But when cultural factors and the social relations governing them are examined in a comparative study of ethnic groups, distinct population subgroups may be revealed to have differential migratory patterns. The Soninka and the Poular, two groups highly affected by migration, were chosen for an analysis of the impact of specific historical experiences on migratory behavior. A historical analysis of colonial archives and anthropological and historical monographs and the 1982-83 "Survey of Migration in the Valley of the Senegal River" provided data. The survey indicated that Soninka and Poular migratory patterns differed from each other, but that both differed from the migratory patterns of all other ethnic groups in the region. Soninka migration is international and oriented primarily toward Europe. It has recently become more intense than that of the poular. The determinants of migration in the two groups appear related more to the structure of households than to lack of educational and health facilities or even of food at the village level. Pastoral life and its associated beliefs and religious ideology appear to have been the principal determinants of precolonial movement among the Poular, while Soninka migration responded more to competition over control of manpower. Itinerant commercial activity was coupled with use of slave labor to ensure food production. But the suppression of slavery and crises of subsistence aggravated by colonial policy provoked ever more distant migration, which found a focus in the French demand for labor after World War II. Migration as an alternative does not appear to have been as significant for the Poular until more recently, when subsistence agriculture and the sale of animals were no longer sufficient to cover monetary needs. Male migration among the Soninka is a

    Diallo, Adja Madjiguene

    Polyploidy is defined as possession of more than two sets of chromosomes of an organism. It is known to play a major role in evolution of organisms, but few studies are available on Sahelian trees. In the case of Acacia senegal (distributed across the Sahel), it is important to clarify the...... potential role of polyploidy in adaptation to dry growth conditions. This thesis therefore aims at increasing the understanding of polyploidization in adaptation of A. senegal by the means of population genetics and quantitative genetic tools. An assessment of the distribution of polyploids across ten...... populations within cytotypes revealed that the studied polyploid populations were more differentiated than diploid ones. The analysis of genetic relationships further suggest multiple origins of polyploid A. senegal and provide novel information for understanding the evolutionary history of the recently...

  1. Liquefied Petroleum Gases (LPG) and the fight against deforestation: the Senegal example

    International Nuclear Information System (INIS)

    Domestic LPG consumption in Senegal is over 40,000 tonnes in 1992, thus preserving more than 33,000 hectares of forest. Three reasons explain the success of the 'butanization' policy implemented by the country in its fight against deforestation: political desire, constant cooperation between the public authorities and distributors, but also a supply of gas and inexpensive cookers. The penetration of these butane cookers on the market occurred mainly in urban areas (it is the leading household appliance of urban families in Senegal), but it is also quite visible in rural areas as well, explained Mr. Boubacar Barry General Manager of Totalgaz Senegal in his speech 'How to fight the Growing Desert with Simple Means and a little imagination' during the 6th World LPG Meeting last October in Marrakech. 2 figs., 3 photos

    2014-09-01

    Full Text Available Mounting evidence from satellite observations of a re-greening across much of the Sahel and Sudan zones over the past three decades has raised questions about the extent and reversibility of desertification. Historical ground data that could help in interpreting the re-greening are scarce. To fill that void, we tapped into the collective memories of local land users from central and western Senegal in 39 focus groups and assessed the spatial association between their perceptions of vegetation changes over time and remote sensing-derived trends. To provide context to the vegetation changes, we also explored the land users' perspective on the evolution of other environmental and human variables that are potentially related to the greening, using participatory research methods. While increases in vegetation were confirmed by the study participants for certain areas, which spatially corresponded to satellite-observed re-greening, vegetation degradation dominated their perceptions of change. This degradation, although spatially extensive according to land users, flies under the radar of coarse-resolution remote sensing data because it is not necessarily associated with a decrease in biomass but rather with undesired changes in species composition. Few significant differences were found in the perceived trends of population pressure, environmental, and livelihood variables between communities that have greened up according to satellite data and those that have not. Our findings challenge the prevailing chain of assumptions of the satellite-observed greening trend indicating an improvement of environmental conditions in the sense of a rehabilitation of the vegetation cover after the great droughts of the 1970s and 1980s, and the improvement of environmental conditions possibly translating into more stable livelihoods and greater well-being of the populations. For monitoring desertification and rehabilitation, there is a need to develop remote sensing

    Lower- and middle-income countries (LMICs) are experiencing rapid changes in access to and use of new internet and digital media technologies. The purpose of this study was to better understand how younger audiences are navigating traditional and newer forms of media technologies, with particular emphasis on the skills and competencies needed to obtain, evaluate and apply health-related information, also defined as health and media literacy. Sixteen focus group discussions were conducted throughout Senegal in September 2012 with youth aged 15-25. Using an iterative coding process based on grounded theory, four themes emerged related to media use for health information among Senegalese youth. They include the following: (i) media utilization; (ii) barriers and conflicts regarding media utilization; (iii) uses and gratifications and (iv) health and media literacy. Findings suggest that Senegalese youth use a heterogeneous mix of media platforms (i.e. television, radio, internet) and utilization often occurs with family members or friends. Additionally, the need for entertainment, information and connectedness inform media use, mostly concerning sexual and reproductive health information. Importantly, tensions arise as youth balance innovative and interactive technologies with traditional and conservative values, particularly concerning ethical and privacy concerns. Findings support the use of multipronged intervention approaches that leverage both new media, as well as traditional media strategies, and that also address lack of health and media literacy in this population. Implementing health-related interventions across multiple media platforms provides an opportunity to create an integrated, as opposed to a disparate, user experience. PMID:25113152

    The purpose of this one-year cross-sectional study conducted in 1997 was to estimate the direct cost of stroke management in the Neurology Department of Fann University Hospital in Dakar, Senegal. Data were collected about the type of care services required and related spending. Cost analysis was made in CFA Francs (CFAF), the Senegalese currency (1 USD = 500 CFAF in 1997). A total of 1260 patients were hospitalized in the department including 383 for stroke (30.4%). Mean age was 60.8 +/- 14.2 years and men accounted for 49.2% of the population. The mortality rate was 46.2% among hospitalized patients. A total of 33,573 medical acts were carried out including 12,052 (35.9%) for stroke management. The direct cost of stroke management was 32,614,442 CFAF with a mean cost of 78,426 CFAF per patient. The cost was 18,839 CFAF in the patient care unit (57.8%) and 4,954,635 CFAF in the neuroradiology unit (15.2%). The cost of health care personnel was 19,373,172 CFAF (59.4%) and the cost for drugs and other medical products was 8,253,246 CFAF. Health education programs aimed at increasing awareness of risk factors are needed to reduce the cost of stroke management in this difficult economic period. PMID:16465816

  5. Summary of Reports from the Country Representatives: Senegal

    International Nuclear Information System (INIS)

    Malaria Situation: Malaria is the main cause of morbidity in Senegal and accounts for 7,000 deaths/year. There has been an increase in the number of severe malaria cases as well as new epidemics in irrigated areas and in peri-urban situations. Drug resistance is extensive and increasing but chloroquine is still effective. Drug resistance has had a major impact on child mortality. The front-line drug is chloroquine which can be substituted by amodiaquine. The second line treatment is sulfadoxin-pyrimethamin (SP) and for severe cases quinine is used. There is some evidence that resistant gametocytes are more infectious than sensitive ones. Epidemiology: In the Sahelian and Sahelo-sudanian areas An. arabiensis is the most abundant species but in the Sudanian region An. funestus and An. gambiae occur in larger numbers. The infection rate is generally lower in An. arabiensis where it co-exists with An. gambiae. There is fairly widespread resistance to DDT but permethrin and deltamethrin are still effective. Malaria Control: There are 38 impregnated bednet centres giving 25% coverage and operated by 152 trained technicians. In Dakar and other urban areas house spraying is used.

    Beyond assessment and analysis of observed and simulated malaria parameters, this study is furthermore undertaken in the framework of predictability of malaria outbreaks in Senegal and remote regions in Sahel, which are found to take place two months after the rainy season. The predictors are the sea surface temperature anomalous patterns at different ocean basins mainly over the Pacific and Atlantic as they are related to changes in air temperature, humidity, rainfall and wind. A relationship between El Niño and anomalous malaria parameters is found. The malaria parameters are calculated with the Liverpool Malaria Model (LMM) using meteorological datasets from different reanalysis products. A hindcast of these parameters is performed using the Sea Surface temperature based Statistical Seasonal ForeCAST (S4CAST) model developed at UCM in order to predict malaria parameters some months in advance. The results of this work will be useful for decision makers to better access to climate forecasts and application on malaria transmission risk.

    2001-01-01

    Over 24 years, from 1976 to 1999, we conducted a prospective study of overall and cause-specific mortality among the population of 42 villages of south-eastern Senegal. Of 4228 deaths registered during this period, 26 were caused by snakebite, 4 by invertebrate stings and 8 by other wild or domestic animals. The average annual mortality rate from snakebite was 14 deaths per 100,000 population. Among persons aged > or = 1 year, 0.9% (26/2880) of deaths were caused by snakebite and this cause represented 28% (26/94) of total deaths by accidents. We also investigated the snake fauna of the area. Of 1280 snakes belonging to 34 species that were collected, one-third were dangerous and the proportion of Viperidae, Elapidae and Atractaspidae was 23%, 11% and 0.6%, respectively. The saw-scaled viper Echis ocellatus was the most abundant species (13.6%). Other venomous species were Causus maculatus (6.5%), Naja katiensis (5.5%), Bitis arietans (2.7%), Elapsoidea trapei (2.4%), Naja nigricollis (1.2%), Naja melanoleuca (1.1%), Atractaspis aterrima (0.4%), Dendroaspis polylepis (0.3%) and Naja haje (0.1%).

  15. Preliminary survey of ticks (Acari : Ixodidae on cattle in northern Sudan

    Directory of Open Access Journals (Sweden)

    D.A. Salih

    2004-11-01

    Full Text Available In a cross sectional survey conducted during the period June 2001 to July 2002, the geographical distribution of ticks on cattle in the Sudan was determined. Seventeen locations were surveyed from Northern, Central, Eastern, Western, Blue Nile and White Nile Provinces. Total body collections of ticks were made from 20 cattle at each location. Four tick genera and 11 species were identified. The tick species collected included Amblyomma lepidum, Amblyomma variegatum, Boophilus decoloratus, Hyalomma anatolicum anatolicum, Hyalomma dromedarii, Hyalomma impeltatum, Hyalomma marginatum rufipes, Hyalomma truncatum, Rhipicephalus evertsi evertsi, Rhipicephalus sanguineus group and Rhipicephalus simus simus. Major ecological changes have occurred due to extensive animal movement, deforestation, desertification and establishment of large mechanized agricultural schemes. These factors have certainly affected the distribution of ticks and tick-borne diseases in the Sudan. The absence of A. variegatum and A. lepidum in northern Sudan was not surprising, since these tick species are known to survive in humid areas and not in the desert and semi-desert areas of northern Sudan. The absence of B. annulatus in northern and central Sudan is in accordance with the finding that this tick species is restricted to the southern parts of the central Sudan. The presence of H. anatolicum anatolicum in Um Benin in relatively high abundance is an interesting finding. The present finding may indicate that the southern limit of this species has changed and moved southwards to latitude 13o N. It is concluded that major changes in tick distribution have taken place in the Sudan

  16. Summary of Reports from the Country Representatives: Sudan

    International Nuclear Information System (INIS)

    Geography: Sudan is the largest country in Africa with a total area of 2.6M km2 and malaria endemicity increases from north to south as the isohytes increase. Malaria Situation: Malaria is hypoendemic in the north, meso-endemic in the central regions and some holoendemic transmission in the south where transmission is perennial. Epidemiology: P. falciparum is the main parasitic species and malaria prevalence was 12.75 in 1998. There are 31 species of Anopheles identified in Sudan, 18 of which are malaria infectious. An. arabiensis is the principal vector and is distributed thoughout the country. An. funestus and An. gambiae are vectors in the south. An. arabiensis is highly endophilic except in the east and is strongly anthropophilic. The species is well adapted to dry conditions and in the seasonal breeding areas the vector density can be virtually zero. It is not clear how these areas become re-infested in the rainy season. There is little inversion polymorphism in Sudanese populations of An. arabiensis. Malaria Control: Mosquito control activities focus mainly on residual house spraying but with some fogging activities in irrigated areas. Malathion house spraying is used in Khartoum but the use of impregnated bed nets is not popular. There is also some aerial spraying.

    Outbreaks of infections with chikungunya virus (CHIKV) have previously been reported from Sudan but the prevalence in the general population is unknown. We investigated the seroprevalence of CHIKV infection in 379 serum samples from patients with fever in the outpatient clinics of three hospitals in eastern and central Sudan. The seroprevalence was 1.8%, indicating that CHIKV infections are rare in these parts of Sudan. As the vector Aedes aegypti is endemic in this area, the population is at risk for a CHIKV epidemic.

  2. Medication administration errors in Eastern Saudi Arabia

    International Nuclear Information System (INIS)

    To assess the prevalence and characteristics of medication errors (ME) in patients admitted to King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia. Medication errors are documented by the nurses and physicians standard reporting forms (Hospital Based Incident Report). The study was carried out in King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia and all the incident reports were collected during the period from January 2008 to December 2009. The incident reports were analyzed for age, gender, nationality, nursing unit, and time where ME was reported. The data were analyzed and the statistical significance differences between groups were determined by Student's t-test, and p-values of <0.05 using confidence interval of 95% were considered significant. There were 38 ME reported for the study period. The youngest patient was 5 days and the oldest 70 years. There were 31 Saudis, and 7 non-Saudi patients involved. The most common error was missed medication, which was seen in 15 (39.5%) patients. Over 15 (39.5%) of errors occurred in 2 units (pediatric medicine, and obstetrics and gynecology). Nineteen (50%) of the errors occurred during the 3-11 pm shift. Our study shows that the prevalence of ME in our institution is low, in comparison with the world literature. This could be due to under reporting of the errors, and we believe that ME reporting should be made less punitive so that ME can be studied and preventive measures implemented (Author).

  3. Stress among dentists in Jeddah, Saudi Arabia

    International Nuclear Information System (INIS)

    The objective of this study was to identify various stress factors affecting dentists and to evaluate their stress manifestations and stress management. A questionnaire was distributed among dentists residing in Jeddah, Saudi Arabia. The questionnaire classified stress factors into professional, patient-related, dental procedure-related, and office management factors. Sign and symptoms of stress manifestations and management were also evaluated. The sample included 80 females and 75 males, with 47% of them below the age of 30 years. Out of the total sample, the largest percentage (60.6%) were general practitioners, 47.7% had experience of less than 5 years and 32.2% had 11 years of experience. The highest mean scores of stress were related to professional factors and dental procedure-related factors. Among those, the main significant factors that caused stress in the surveyed sample were lack of time in relation to workload (76.1%), limited visibility and accessibility (67.7%). The most common manifestations of stress were nervousness (95%), musculoskeletal fatigue (72%) and anger (58%). Dentists predominantly managed their stress by praying and reading holy books (80%) and by spending time alone (75%) or with family and friends (70%). The most prevalent and significant causes of stress among dentists working in Jeddah, Saudi Arabia were professional in nature. Stress has been manifested by nervousness and musculoskeletal problem and was mainly managed by praying and spending time alone or with family and friends. (author)

  7. Selection of the most suitable phosphorus fertilization in some soils of Senegal: use of phosphorus 32

    Energy Technology Data Exchange (ETDEWEB)

    The phosphorus status and phosphorus fertilization of Senegal soils were analyzed by the isotopic dilution kinetics method. With this method, the mobility of phosphate ions is described by four parameters: two of them are related to the quantity of available phosphate and the two others are related to the kinetics of exchange between soil and its bathing solution. All these soils are very poor in available soil phosphorus and fertilization appears necessary to increase cropping intensity. Local ores (rock phosphate and phospal) were tested and compared with superphosphate. In the major part of Senegal, the main plain, where the pluviometry is low or very low, the fixation capacity is restricted: superphosphate increased easily available phosphorus but the productivity of soils is restricted by the lack of water. Near the great rivers -Casamance and Senegal Rivers-, where irrigation becomes a great possibility, the fixation capacity of soils for phosphate ions is very high. For this reason, near the river, in the North of Senegal, superphosphate does not increase available phosphorus even when in large quantity and it seems useful to spread rock phosphate which is cheap compared to superphosphate. In this case, the aim of the agronomist must be the maintenance of soil phosphorus status.

    The Sahara desert transports large quantities of dust over the Sahelian region during the Northern Hemisphere winter and spring seasons (December-April). In episodic events, high dust concentrations are found at the surface, negatively impacting respiratory health. Bacterial meningitis in particular is known to affect populations that live in the Sahelian zones, which is otherwise known as the meningitis belt. During the winter and spring of 2012, suspected meningitis cases (SMCs) were with three times higher than in 2013. We show higher surface particular matter concentrations at Dakar, Senegal and elevated atmospheric dust loading in Senegal for the period of 1 January-31 May during 2012 relative to 2013. We analyze simulated particulate matter over Senegal from the Weather Research and Forecasting (WRF) model during 2012 and 2013. The results show higher simulated dust concentrations during the winter season of 2012 for Senegal. The WRF model correctly captures the large dust events from 1 January-31 March but has shown less skill during April and May for simulated dust concentrations. The results also show that the boundary conditions are the key feature for correctly simulating large dust events and initial conditions are less important.

    Full Text Available The construction of the Diama dam on the Senegal river, the Manantali dam on the Bafing river, Mali and the ensuing ecological changes have led to a massive outbreak of Schistosoma mansoni in Northern Senegal, associated with high intensity of infections, due to intense transmission, and the creation of new foci of S. haematobium. Data on the vectorial capacity of Biomphalaria pfeifferi from Ndombo, near Richard Toll, Senegal are presented with sympatric and allopatric (Cameroon S. mansoni. Comparisons are made on infectivity, cercarial production, chronobiology of cercarial emergence and longevity of infected snails. Recent data on the intermediate host specificity of different isolates of S. haematobium from the Lower and Middle Valley of the Senegal river basin (SRB demonstrate the existence of at least two strains of S. haematobium. The role of Bulinus truncatus in the transmission of S. haematobium in the Lower and Middle Valleys of the SRB is reviewed. Both S. haematobium and S. mansoni are transmitted in the same foci in some areas of the SRB.

    2016-01-01

    Polyploidy is a common phenomenon in the evolution of angiosperms. It has been suggested that polyploids manage harsh environments better than their diploid relatives but empirical data supporting this hypothesis are scarce, especially for trees. Using microsatellite markers and flow cytometry, we examine the frequency of polyploids and diploids in a progeny trial testing four different populations of Acacia senegal, a species native to sub-Saharan regions of Africa. We compare growth between cytotypes and test whether polyploid seedlings grow better than diploids. Our results show that polyploids coexist with diploids in highly variable proportions among populations in Senegal. Acacia senegal genotypes were predominantly diploid and tetraploid, but triploid, pentaploid, hexaploid, and octaploid forms were also found. We find that polyploids show faster growth than diploids under our test conditions: in an 18 years old field trial, polyploid superiority was estimated to be 17% in trunk diameter and 9% in height while in a growth chamber experiment, polyploids grew 28% taller, but only after being exposed to drought stress. The results suggest that polyploid A. senegal can have an adaptive advantage in some regions of Africa. PMID:27379120

    Full Text Available Among arid zone tree species, Acacia senegal and Prosopis cineraria are the most important dryland resources of Western Rajasthan desert ecosystem. Due to ecological, biological and molecular similarities, they are often studied together. The climatic conditions in this region restrict the build-up of soil organic matter and soils are generally deficient in nitrogen. Studies were carried out to isolate and molecularly characterize the diverse group of plant growth promoting rhizobacteria from root nodules of native A. senegal and P. cineraria and their effect on seed germination and seedling traits in two genotypes of A. senegal. The direct sequencing of 16S rDNA region resulted in molecular identification of plant growth promoting rhizobacteria as Bacillus licheniformis, Sinorhizobium saheli isolated from root nodules of A. senegal and S. kostiense and S. saheli isolated from root nodules of P. cineraria. The partial sequences of 16S rDNA were assigned Gen accession numbers HQ738496, HQ738499, HQ738506 and HQ738508. Scarification treatment with sulphuric acid (98% for 15 minutes was able to break the exogenous seed dormancy and enhanced germination percentage in control treatment to 90% and 92.5% in A. senegal in genotypes CAZRI 11113AS and CAZRI 35AS, respectively. The treatments with Bacillus licheniformis or S. kostiense, either inoculated individually or as coinoculants, had positive effect on phenotypic traits of germination. Two A. senegal genotypes exhibited significant differences with regard to all the phenotypic traits. On the other hand, treatments with S. saheli isolated from either A. senegal or P. cineraria had negative effects on germination and related phenotypic traits. Values of the coeffivient of determination (R2 over 80% for root length versus shoot length, root/shoot ratio and seedling weight respectively validate that the observed attributes are inter-dependable and linear progression trend can be

  4. Transboundary water resources management and livelihoods: interactions in the Senegal river

    2016-04-01

    In Sub-Saharan Africa, 90 % of wetlands provide ecosystem services to societies, especially for agriculture and fishing. However, tropical rivers are increasingly regulated to provide hydroelectricity and irrigated agriculture. Modifications of flows create new hydrological conditions that affect floodplains ecology and peoples' livelihoods. In the Senegal river valley, large dams were built during the 1980's to secure water resources after a decade of water scarcity in the 1970's: Manantali in the upper basin with a reservoir of 12km3 and Diama close to estuary to avoid saltwater intrusion during dry season. Senegal river water resources are known under the supervision of Senegal River Basin Development Organization (OMVS), which defines water allocation between different goals (electricity, irrigation, traditional activities). This study, based on the concept of socio-hydrology, analyses socio-ecological changes following thirty years of dam management. The work enlightens adaptation mechanisms of livelihoods from people living along the river floodplain and feedback on water ressources. The study uses a mixed method approach, combining hydrological analyses, literature review and data collection from surveys on stakeholders and key informants level in the middle Senegal valley. Our results suggest that in all the Senegal river valley, socio-ecological changes are driven by new hydrological conditions. If dam management benefit for peoples with electrification and development of an irrigated agriculture, it has also emphasized the floodplain degradation. Flooded area has decline and are more irregular, causing an erosion of floodplain supporting services (traditional activities as fishing, grazing and flood-recession agriculture). These conditions reduce peoples' livelihood possibilities and irrigation is the only regular activity. As a feedback, irrigated agriculture increases withdrawals in the river and, recently, in aquifers posing a new uncertainty on water

    2014-08-01

    Full Text Available This study is about the revolution of information and communication technology (ICT. It deals with the evolution of banking technology (BT, electronic banking (e-banking and mobile banking (m-banking in Sudan. It intends to explore the practice of m-banking in Sudan. The focus is on the availability of adequate infrastructure and on the challenges and risks that face m-banking services in Sudan. The findings showed that although mbanking is believed to be essential, still the services provided are at an infant stage. It is also found that concerned parties are not fully cooperating. This raises risks and constitutes challenges that hinder full utilization of m-banking in Sudan. Based on these results, the main recommendation of the researchers was that regulatory policies should be stated clearly to ensure full collaboration between all concerned parties. This is to support bank managers and decision makers in formulating their strategic plans to deliver competitive services.

This study summarizes recent scientific evidence of environmental and occupational links to nearly 30 types of cancer. the discussion of each cancer type is introduced by highlights of trends in incidence. The study considers additional indication that involuntary exposures are linked to cancers, such as patterns observed in different geographic areas and among different population patterns of cancer in children. The purpose of this study is to review scientific evidence, particular y epidemiologic evidence. regarding the contribution of environmental and occupational exposures to the overall cancer incidence in the Sudan. The study discussed that the widespread exposures from air and water pollution, the work environment, exposure resulting form personal habits such as smoking and drinking and the diet are major contributors to cancer in human. In the past three decades, there have been several efforts to estimate the proportion of caner due to these involuntary exposure, starting with an ambitious effort by different scientists. This study provided and alternative interpretation of the evidence of cancer incidence to particular factors. We conclude the study by recommending the significance of giving environmental and occupational links to cancer serious consideration by individuals and institutions concerned with cancer prevention, particularly those involved in research and education.

  10. Multi Plumes and Their Flows beneath Arabia and East Africa

    Science.gov (United States)

    Chang, S.; van der Lee, S.

    2010-12-01

    The three-dimensional S-velocity structure beneath Arabia and East Africa is estimated down to the lower mantle to investigate vertical and horizontal extension of low-velocity anomalies that bear out the presence of mantle plumes and their flows beneath lithosphere. We estimated this model through joint inversion of teleseismic S- and SKS-arrival times, regional S- and Rayleigh waveform fits, fundamental-mode Rayleigh-wave group velocities, and independent Moho constraints from receiver functions, reflection/refraction profiles, and gravity measurements. With the unprecedented resolution in our S-velocity model, we found different flow patterns of hot materials upwelling beneath Afar beneath the Red Sea and the Gulf of Aden. While the low-velocity anomaly from Afar is well confined beneath the Gulf of Aden, inferring mantle flow along the gulf, N-S channel of low velocity is found beneath Arabia, not along the Red Sea. The Afar plume is distinctively separate from the Kenya plume, showing its origin in the lower mantle beneath southwestern Arabia. We identified another low-velocity extension to the lower mantle beneath Jordan and northern Arabia, which is thought to have caused volcanism in Jordan, northern Arabia, and possibly southern Turkey. Comparing locations of mantle plumes from the joint inversion with fast axes of shear-wave splitting, we confirmed horizontal plume flow from Afar in NS direction beneath Arabia and in NE-SW direction beneath Ethiopia as a likely cause of the observed seismic anisotropy.

    2014-01-01

    Full Text Available Achieving and maintaining a stable nursing workforce is an important issue for the well-being of the rapidly growing population of Saudi Arabia. However, high turnover of expatriate staff and low recruitment of Saudi nationals have led to a serious staff shortage in the professions, particularly of well-qualified and experienced nurses. Nursing leaders need to work to improve the image of nurses and facilitate the recruitment of women into the nursing profession. Reduced working hours and part-time contracts with increased salaries and benefits could attract more young women to the profession, as might the provision of facilities such as private transportation and on-site childcare. Furthermore, establishing a national association for nurses would advance the nursing profession and help to ensure that all nurses undertake fully comprehensive training before entering the workforce.

    Full Text Available This paper studies the education-employment nexus in the context of Senegal. Using the 2005 Senegal Household Survey, we find that households’ heads with higher education (lower secondary level and above are less likely to be self-employed but more likely to be working in the public sector. Disaggregation by gender and location (rural vs. urban does not affect the results. Besides, female headed households with secondary education and above are more likely to be employed in the private sector. The results suggest the importance of steps for extensive promotion of education (especially for an upward revision of the level of compulsory education in resolving the persistent unemployment problem and improving the job availability in the private sector.

    The bacterium Tropheryma whipplei, which causes Whipple disease in humans, is commonly detected in the feces of persons in Africa. It is also associated with acute infections. We investigated the role of T. whipplei in febrile patients from 2 rural villages in Senegal. During June 2010-March 2012, we collected whole-blood finger-prick samples from 786 febrile and 385 healthy villagers. T. whipplei was detected in blood specimens from 36 (4.6%) of the 786 febrile patients and in 1 (0.25%) of the 385 apparently healthy persons. Of the 37 T. whipplei cases, 26 (70.2%) were detected in August 2010. Familial cases and a potential new genotype were observed. The patients' symptoms were mainly headache (68.9%) and cough (36.1%). Our findings suggest that T. whipplei is a cause of epidemic fever in Senegal. PMID:27314980

    Schistosomiasis is the second most significant parasitic disease in children in several African countries. For this purpose, the "Programme National de Lutte contre les Bilharzioses" (PNLB) was developed in partnership with the World Health Organization (WHO) to control this disease in Senegal. However, geographic isolation of Bedik ethnic groups challenged implementation of the key elements of the schistosomiasis program in eastern Senegal, and therefore, a hospital was established in Ninefescha to improve access to health care as well as laboratory support for this population. The program we have implemented from 2008 in partnership with the PNLB/WHO involved campaigns to 1) evaluate schistosomiasis prevalence in children of 53 villages around Ninefescha hospital, 2) perform a mass drug administration following the protocol established by the PNLB in school-aged children, 3) monitor annual prevalence, 4) implement health education campaigns, and 5) oversee the building of latrines. This campaign led to a drop in schistosomiasis prevalence but highlighted that sustainable schistosomiasis control by praziquantel treatment, awareness of the use of latrines, and inhabitants' voluntary commitment to the program are crucial to improve Schistosoma elimination. Moreover, this study revealed that preschool-aged children, for whom praziquantel was not recommended until 2014 in Senegal, constituted a significant reservoir for the parasite. PMID:27430549

    Approximately 700,000 women in Senegal have suffered female genital mutilation (FGM). Now, following a vote upon legislation banning FGM, public opinion in the country over the practice is more divided than ever. The practitioners of FGM are not taking the law seriously, while politicians hesitate to openly condemn the practice, which still occurs widely in rural zones. Most of the 140 parliamentarians do not believe that laws alone can successfully end FGM in Senegal. Some deputies and feminists believe that several years of sensitization on the issue will be needed to effectively reduce the frequency with which FGM is practiced. Only optimists believe FGM will disappear on its own. The debate threatens to resurface in some areas during the year 2000 presidential election. One deputy from the governing party, originally from southern Senegal, states that he dares not tell his constituency that the president himself created the anti-FGM legislation, especially when locally elected leaders finance villages¿ FGM-related celebrations. According to a scholar of the Koran, FGM is an Islamic practice, but it is not taught in the Koran. FGM is therefore a cultural practice borne from individual choice. In Kolda, 650 km south of Dakar, the practitioners of such mutilation argue that they would rather be imprisoned than abandon the practice they consider to be an immutable component of their cultural history.

    Arid countries like Saudi Arabia often depend on fossil groundwater. Hence, thorough studies of the available resources are crucial. In the course of such investigations, analyses of δ18O and δD are frequently applied to constrain the provenance of the waters and to reconstruct the (paleo)climatic conditions during their recharge. Yet, to be able to evaluate the isotopic signature of the groundwater, one also has to know the isotopic composition of current precipitation. Although a few rain water analyses are available for Central Saudi Arabia in the literature - mostly in unpublished consultant reports - a Local Meteoric Water Line has never been established. To complement the available data, 28 rain events occurring in Riyadh between 2009 and 2013 were studied for their stable isotope composition. Samples were collected as integral samples, i.e., they represent the entire precipitation event. Moreover, one event was sampled several times, aiming at an evaluation of intra-storm variability. During selected storms, a grab sample was taken for 3H analysis. The event samples showed δ18O and δD values scattering between -6.5 and +9.5 and between -30 and +50 ‰ V-SMOW, respectively. In the course of the event that was sequentially sampled, a proceeding isotopic depletion was observed with respect to both isotopes. The relatively large ranges of δ-values for 18O and D of approximately 7 and 38 ‰ V-SMOW highlight the general need for integral sampling. The obtained grab samples are characterized by moderate 3H concentrations of a few Tritium Units. Further results will be presented and discussed in view of associated weather data (e.g. rain amount and temperature) and the probable moisture sources derived from back-trajectories, which were calculated using HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory Model; Draxler & Rolph, 2003).

  7. Mantle plumes and associated flow beneath Arabia and East Africa

    Chang, Sung-Joon; Van der Lee, Suzan

    2011-02-01

    We investigate mantle plumes and associated flow beneath the lithosphere by imaging the three-dimensional S-velocity structure beneath Arabia and East Africa. This image shows elongated vertical and horizontal low-velocity anomalies down to at least mid mantle depths. This three-dimensional S-velocity model is obtained through the joint inversion of teleseismic S- and SKS-arrival times, regional S- and Rayleigh waveform fits, fundamental-mode Rayleigh-wave group velocities, and independent Moho constraints from receiver functions, reflection/refraction profiles, and gravity measurements. In the resolved parts of our S-velocity model we find that the Afar plume is distinctly separate from the Kenya plume, showing the Afar plume's origin in the lower mantle beneath southwestern Arabia. We identify another quasi-vertical low-velocity anomaly beneath Jordan and northern Arabia which extends into the lower mantle and may be related to volcanism in Jordan, northern Arabia, and possibly southern Turkey. Comparing locations of mantle plumes from the joint inversion with fast axes of shear-wave splitting, we confirm horizontal mantle flow radially away from Afar. Low-velocity channels in our model support southwestward flow beneath Ethiopia, eastward flow beneath the Gulf of Aden, but not northwestwards beneath the entire Red Sea. Instead, northward mantle flow from Afar appears to be channeled beneath Arabia.

    Full Text Available The main purpose of this research was to gain an understanding of the adoption behavior of mobile computing in Saudi Arabia. In particular, it aimed to acquire new insight into mobile computing trends, specifically in Saudi Arabia, in order to develop hypotheses and formulate precise criteria for mobile computing evaluation. In order to achieve these aims, the researcher created a focus group by recruiting eight participants with solid background knowledge of usability engineering and mobile computing. The focus group proposed a four-phase process: determination, qualification, categorization and evaluation of the mobile computing applications developed by Saudi organizations. During the determination phase, two hundred and twenty seven (n=227 mobile applications were determined as having been developed by organizations in Saudi Arabia. During the qualification phase, one hundred and forty two (n=142 mobile applications were qualified. Within the categorization phase, the experts categorized only the qualified applications into a two-level categorization hierarchy. Finally, in the evaluation phase, the qualified applications were evaluated in terms of purpose, platform, visual appearance, content, organization and usability. The results herein revealed that 43% of the mobile applications in Saudi Arabia were M-Government applications, while 57% were M-Business applications. In addition, the study proposed a sample of thirty six (n=36 applications as having statistical significance from all of the mobile applications in Saudi Arabia.

  9. Human African trypanosomiasis in South Sudan: how can we prevent a new epidemic?

    Directory of Open Access Journals (Sweden)

    José A Ruiz-Postigo

    Full Text Available Human African trypanosomiasis (HAT has been a major public health problem in South Sudan for the last century. Recurrent outbreaks with a repetitive pattern of responding-scaling down activities have been observed. Control measures for outbreak response were reduced when the prevalence decreased and/or socio-political crisis erupted, leading to a new increase in the number of cases. This paper aims to raise international awareness of the threat of another outbreak of sleeping sickness in South Sudan. It is a review of the available data, interventions over time, and current reports on the status of HAT in South Sudan. Since 2006, control interventions and treatments providing services for sleeping sickness have been reduced. Access to HAT diagnosis and treatment has been considerably diminished. The current status of control activities for HAT in South Sudan could lead to a new outbreak of the disease unless 1 the remaining competent personnel are used to train younger staff to resume surveillance and treatment in the centers where HAT activities have stopped, and 2 control of HAT continues to be given priority even when the number of cases has been substantially reduced. Failure to implement an effective and sustainable system for HAT control and surveillance will increase the risk of a new epidemic. That would cause considerable suffering for the affected population and would be an impediment to the socioeconomic development of South Sudan.

    A novel method for the extraction of Sudan dyes including Sudan I, II, III, and IV from environmental water by magnetic titanium dioxide nanoparticles (Fe3O4@TiO2) coated with sodium dodecylsulfate (SDS) as adsorbent was reported. Fe3O4@TiO2 was synthesized by a simple method and was characterized by transmission electron microscopy, Fourier-transform infrared spectrometry, and vibrating sample magnetometer. The magnetic separation was quite efficient for the adsorption and desorption of Sudan dyes. The effect of the amount of SDS, extraction time, pH, desorption condition, maximal extraction volume, and humic acid on the extraction process were investigated. This method was employed to analyze three environmental water samples. The results demonstrated that our proposed method had wide linear range (25-5,000 ng L(-1)) with a good linearity (R (2) > 0.999) and low detection limits (2.9-7.3 ng L(-1)). An enrichment factor of 1,000 was achieved. In all three spiked levels (25, 250, and 2,500 ng L(-1)), the recoveries of Sudan dyes were in the range of 86.9-93.6 %. The relative standard deviations obtained were ranging from 2.5 to 9.3 %. That is to say, the new method was fast and effective for the extraction of Sudan dye from environmental water.

    1995-06-01

    Full Text Available Armed conflicts in the Horn of Africa have been raging in that region for the last forty years with tragic consequences for human life and for economic advancement. These conflicts have three different, but overlapping dimensions: the intrastate, the interstate, and the global levels. The conflicts are of a decided relevance for the Sudan, and particularly to the rebellion in the southern Sudan. The lack of security and stability in southern Sudan forced hundreds of thousand southerners into neighbouring countries, especially Ethiopia and Uganda. Likewise, the Sudan hosted hundreds of thousands Eritreans, Ethiopians, and Ugandans caught in the crossfire of their national conflicts. This development not only created a heavy economic burden on these relatively poor and economically underdeveloped communities, but led to strained political relations among governments. The Sudan has deep-seated security concerns emanating from the tragic developments in that part of the world. It is argued that one practical step to defuse the situation is to look for political solutions for essentially political problems. The next step that follows logically from the first step is to establish economic cooperation arrangements with a view to creating a future economic community in that African region.

  13. Ancient Hydrothermal Springs in Arabia Terra, Mars

    Science.gov (United States)

    Oehler, Dorothy Z.; Allen, Carlton C.

    2008-01-01

    Hydrothermal springs are important astrobiological sites for several reasons: 1) On Earth, molecular phylogeny suggests that many of the most primitive organisms are hyperthermophiles, implying that life on this planet may have arisen in hydrothermal settings; 2) on Mars, similar settings would have supplied energy- and nutrient-rich waters in which early martian life may have evolved; 3) such regions on Mars would have constituted oases of continued habitability providing warm, liquid water to primitive life forms as the planet became colder and drier; and 4) mineralization associated with hydrothermal settings could have preserved biosignatures from those martian life forms. Accordingly, if life ever developed on Mars, then hydrothermal spring deposits would be excellent localities in which to search for morphological or chemical remnants of that life. Previous attempts to identify martian spring deposits from orbit have been general or limited by resolution of available data. However, new satellite imagery from HiRISE has a resolution of 28 cm/pixel which allows detailed analysis of geologic structure and geomorphology. Based on these new data, we report several features in Vernal Crater, Arabia Terra that we interpret as ancient hydrothermal springs.

    Full Text Available Abstract The global malaria situation, especially in Africa, and the problems frequently encountered in chemical control of vectors such as insecticide resistance, emphasize the urgency of research, development and implementation of new vector control technologies that are applicable at regional and local levels. The successful application of the sterile insect technique (SIT for the control of the New World screwworm Cochliomyia hominivorax and several species of fruit flies has given impetus to the use of this method for suppression or elimination of malaria vectors in some areas of Africa including Northern State of Sudan. The research and development phase of the Northern State feasibility study has been started. Sudanese stakeholders are working side-by-side with the International Atomic Energy Agency in the activities of this important phase. Several ethical, legal and social issues associated with this approach arose during this phase of the project. They need to be seriously considered and handled with care. In this paper, these issues are described, and the current and proposed activities to overcome potential hurdles to ensure success of the project are listed.

    Full Text Available Jir hur is a traditional fermented food of the Fur tribe of western Sudan prepared from bulrush millet (Penisitum typhoidism. The microbiological changes during the fermentation stages were monitored. LAB count increased from 4.48 in raw millet to 7.19 log/cfug in jir hur and yeast count increased from 3.77 to 7.55 log/cfug, respectively with significant changes in pH from 6.66 in raw millet to 3.68 in jir hur. The fermentation of millet into jir was a homo-lactic acid fermentation that involved a complex microbial succession between LAB and yeast. LAB was the predominant microorganisms during the first fermentation with significant increase in yeast counts. Pediococcus halophilus, Pediococcus inopinatus and Pediococcus urinaeequi were the dominant lactic acid bacteria species at all times with the association of Lactobacillus acidophilus and Lactobacillus jensenii at the second fermentation. The yeast species Schizosaccharomyces pombe, Saccharomycods sinensis and Trichosporon adeninovorans were followed in succession during jir fermentation stages.

    Full Text Available This field study was conducted between Oct 2005 and Aug 2008 in Gedarif state, eastern Sudan. The objective was to provide knowledge on constraints faced by camel herders, and to identify the solutions as an essential step towards the development of camel herding in this state. A set of detailed structured questionnaires were used to collect information from camel herders. The results showed that, nomadic tribes in the study area (58.8% represented by Lahaween and Rofaah tribes and their dwelling type is tents made from (Hair & wool. Semi nomadic tribes (30.9% represented by Kenana and Rashaida tribes and their dwelling type is cottage made from branches of trees and sorghum stalk and the sedentary tribe (10.3% represented by Shokria tribes and their dwelling type are buildings made from either mud or bricks with cement. There was a high percent of family members who are illiterate. It was clear that the level of provision of most services needed by the herders and owners is relatively very low. The camel owners annually need to sell 5 to 6 camels to feed 100 camels on sorghum stalks in the dry season. The serious livelihood constraints were education, electricity, water supply and veterinary services. More care from the government and non government organizations is recommended.

  18. Characterisation of phosphate rocks at kurun mountain, Sudan

    International Nuclear Information System (INIS)

    This main objective of this study was to characterise some Sudanese phosphate raw materials collected from Jebel Kurun, located in the eastern part of Nuba Mountain, Western Sudan. The study also aimed to investigate the association between uranium and phosphate and to determine the concentration of some essential elements and trace elements in the phosphate rock. A total of 30 samples were collected from Karun's eastran mountains, near Abujibiha City and have been analyzed for the selected elements using x-ray fluorescence. The obtained results showed that the average concentration of elements was Ca (11.3) and Fe (1.7) as a percentage, while it was Cu (1617.7), Ni (258.4), Pb (185.9), Ti (27.62), V (3779.9), U (160.9), Zn (152.8) and Mn (776.3) in ppm. The average total phosphorus content (analyzed as PO5%) using UV-visible spectrometer was found to be 30.54%. This could be considered is acceptable percentage for phosphate to be 30.54%. This could be considered is acceptable percentage for phosphate to be used in industrial fertilizers and phosphoric acid production. The average total calcium carbonate was 15.7%. For the elements distribution, uranium found to be more concentrated in the summit of Jebel Kurun, and it displayed a correlation with lead. Furthermore, four groups of association have been noticed, based on elements concentrations.(Author)

  19. Studies on simple goitre epidemiology and aetiology in Sudan

    International Nuclear Information System (INIS)

    The objectives of this study were to map the prevalence of goiter in Sudan and to study the etiological factors involved. A further objective was to explore the use of serum thyroglobulin (Tg) level in the assessment of endemic goiter. The survey took place in the period from June to November 2006. The survey covered nine cities including Nyala and Elfasher (Western part), Wau (in the South), Atbara and Dongula (in the north), Dmazine (South East), Port Sudan (Eastern part), Kosti and Khartoum (in the Centre ). Khartoum was divided into three different cities Khartoum, Khartoum North and Omdurman. The study included 6181 male and female schoolchildren at the age 6-12 years old. All the children were clinically examined for the presence of goiter using WHO palpation method. Blood samples were randomly collected from 360 children (30-37) from each selected city irrespective of their thyroid status or gender. Serum samples were analyzed for the concentration of T4, T3, TSH, and Tg. Casual urine samples were also collected from the same selected subjects. Urine samples were analyzed for iodine and thiocyanate concentrations. Water samples were collected from each school and analyzed for the concentration of Ca, Mg, Cl, F and total Hardness. The results indicated that the overall total goiter rate was 40.62%. The highest goiter rate was found in Kosti town (77.67%) and the lowest in Omdurman Khartoum state (12.22%). The overall median urinary iodine excretion (UIE) was 6.55 μg/dl. Iodine deficiency was detected in 70.28% of the children and there were great variations in the median UIE from region to anther started from as low as 2.70μg/d1 in Kosti town 46.40 μg/d1 in Port Sudan city (at the cost of the Red Sed). The overall median concentration of urinary thiocyanate was 0.37 mg/d1. There were also variations in the median levels of urinary thiocyanate from city to another and slightly exceeded the cut off point (0.0.46 mg/d1) in pupils from Wau and Nyala cities

    Background. Youth populations are vulnerable to substance use particularly in developing countries where circumstances may be favorable for it. There is no published data on substance use among the youth in Sudan other than on tobacco use. Objectives. The aim of this study was to investigate the prevalence, circumstances, and factors associated with substance use. Methods. An institution-based survey was conducted on a sample of 500 students. Data was collected using a questionnaire designed by the WHO for student drug surveys and analyzed using IBM SPSS version 20. Results. The overall prevalence of substance use is 31%. The current prevalence of tobacco, cannabis, alcohol, amphetamines, tranquilizers, inhalants, opiates, cocaine, and heroin use was 13.7%, 4.9%, 2.7%, 2.4%, 3.2%, 1%, 1.2%, 0.7%, and 0.5%, respectively. Curiosity (33.1%) was the main reason for initiation of substance use. The main adverse effects reported were health problems (19.7%) and theft (19.7%). Peers (40.9%) were the prime source of substance use. On multivariate analysis, male sex was the principle predictor for substance use (AOR: 5.55; 95% CI: 3.38, 9.17). Conclusion. Strategies to control substance use should encompass the role of the university and parents in observing and providing education to improve awareness of substances and their consequences.

    Roseires Reservoir, located on the Blue Nile River in Sudan, is the first trap to the sediments coming from the vast upper river catchment in Ethiopia, which suffers from high erosion and desertification problems. The reservoir has already lost more than one-third of its storage capacity due to sedimentation in the last four decades. Appropriate management of the eroded soils in the upper basin could mitigate this problem. In order to do that, the areas providing the highest sediment volumes to the river have to be identified, since they should have priority with respect to the application of erosion control practices. This requires studying the sedimentation record inside Roseires Reservoir in order to assess when and how much sediment is deposited and to identify its source. This paper deals with the identification of deposition time and soil stratification inside the reservoir, based on historical bathymetric data, numerical modelling and newly acquired soil data. The remoteness of the study area and the extreme climate result in coring campaigns being expensive and difficult. Therefore, these activities need to be optimised and coring locations selected beforehand. This was done by combining bathymetric data and the results of a depth-averaged morphodynamic model recording the vertical stratification in sediment deposits. The model allowed for recognising the areas that are potentially subject to neither net erosion nor bar migration during the lifespan of the reservoir. Verification of these results was carried out by analysing sediment stratification from the data collected during the subsequent field campaign.

    Full Text Available Abstract Upon the signing of the Comprehensive Peace Agreement in 2005, the Republic of South Sudan (RSS has faced a lot of challenges, such as a lack of infrastructure, human resources and an enormous burden of vector borne diseases including malaria. While a national malaria strategic plan 2006-2011 was developed, the vector control component has remained relatively weak. The strategy endorses the distribution of long-lasting insecticidal nets (LLINs as the frontline intervention with other interventions recommended only when technical and institutional capacity is available. In 2006, a draft integrated vector management (IVM strategic plan 2007–2012 was developed but never implemented, resulting in minimal coordination, implementation and coverage of malaria vector control tools including their inherent impact. To address this challenge, the vector control team of the National Malaria Control Programme (NMCP is being strengthened. With the objective of building national capacity and technical collaboration for effective implementation of the IVM strategy, a national malaria vector control conference was held from 15-17th October 2012 in Juba. A range of NMCP partners, state ministries, acadaemia, private sector, national and international non-governmental organizations, including regional and global policymakers attended the meeting. The conference represented a major milestone and made recommendations revolving around the five key elements of the IVM approach. The meeting endorsed that vector control efforts in RSS be augmented with other interventions within the confines of the IVM strategy as a national approach, with strong adherence to its key elements.

  4. Investigation of radioactivity in flour and bread improvers in Sudan

    International Nuclear Information System (INIS)

    The measurement of radionuclides concentration is useful in determining the radiological risk due to internal dose from flour and bread improvers. From the radiation protection point of view, the main goal is obtain the annual average dose to which of flour and bread improvers commonly used in Sudan has been carried out. Thirty samples have been collected from Khartoum state and measured using gamma spectrometry system. The obtained result showed that ranges of the activity concentrations of detected radionuclides, Cs-137 and K-40 vary between 0.40-8.89 and 8.58- 772.34 Bq.kq-1 respectively. Using estimated data of consumption rates, the annual effective dose for the population has been calculated and found to be 5.6x10-09 mSv/y for Cs-137 and 2.92x10-07 mSv/y for k-40. This value is relativity low if compared with recommended limits of exposure from this route of intake. (Author)

  5. Investigation of soil radioactivity of Alkhwai area central Sudan

    International Nuclear Information System (INIS)

    The present study is the first of its type to be conducted in Alkhwai area aiming at thorough investigation of natural environmental radioactivity. Considerable variation in soil radioactivity with location is observed. Results show that the average concentrations of 238U, 232Th and 40K in soil were found to be 14.79± 2.43, 20.71± 3.59 and 162.09± 21.19 respectively and have the range 10.0-21.98, 13.89-28.55 and from 113.51 to 219.45 respectively. It is observed that there is strong correlation between Uranium-Thorium and fair correlation between Uranium-Potassium and Thorium-Potassium. The average value of calculated gamma radiation dose rate in Alkhwai district was estimated to be (26.10) n Gy h-1 comparable with the world average (59 n Gy/h). The average dose from gamma radiation dose rate to an individual assuming a tropical rural setting is estimated to be 32.03 μSv/year, which is considered to be within the normal range for doses from natural sources. Further measurements of ambient dose for more soil type at different geological features of Sudan are needed to establish a more comprehensive database on the relationship between gamma radiation dose and geological-soil information.

  6. X-ray diffraction analysis of mudstone from nw sudan

    International Nuclear Information System (INIS)

    This study deals with the theoretical and experimental aspects of the x-ray diffraction technique (XRD). The XRD technique is used to investigate fine structure of matter, and it is most efficient method for the determination of the mineralogical composition of rocks. The XRD technique is used also to investigate the clay mineralogical of mud-stones of the Nubian sandstones of north western Sudan. The XRD results revealed that the mud-stone samples are composed, in decreasing abundance's of kaolinite, smectite, chlorite and illite. Non-clay minerals reported include quartz, feldspars and geothite. Kaolinite dominates in most of samples with percentages ranging between 78-96%. Smectite comes second in abundance and ranges between 10-24%, followed by chlorite and illite which showed the lowest abundance's. The dominance of kaolinite over smectite indicates that intense chemical weathering and leaching occurred under warm humid climate interrupted by dry periods. Most probably these clay minerals were produced by inheritance and partly by neo formation. The variation of the chemical composition of these mud stones is due basically to differences in clay mineralogy which was controlled by source rock geology, weathering physicochemical behavior of elements, local environment and climatic condition in the past.

  7. Phytochemical studies of flavonoids from polygonum glabrum L of Sudan

    International Nuclear Information System (INIS)

    A semi- aquatic plant, Polygnum glabrum wild of the family polygonaceae was reported in traditional medicine of Sudan as anthelmintic and as a remedy against intestinal colics.The literature reported the isolation and structure elucidation of the bioactive agents as being sequi terpenes. The flavonoids of the Sudanese species were not investigated before. The present work consisted of phyto chemical study of the leaves of Polygonum galbrum wild. Before experimentation, a through authentication of the plant was done to correct previously reported errors. In the first stages a phyto chemical screening was made which confirmed the presence of flavonoid compounds in higher amounts than the other classes of natural products present in the plant. Different chromatographic techniques of isolation were assayed but the fractionation of flavonoids was successfully done with preparative thin layer chromatographic techniques. Yellow crystals, namely (two compounds) were obtained in pure form and identified as being flavonoids. Spectral studies were performed on Infra-Red and Ultra- Violet spectrophotometers. The computerized Ultra- Violet spectrophotometer allowed us to obtain complete data about the studied compounds. Structure elucidation was attempted and the structure of the isolated flavonoids were suggested as being Isorhamnetin and Diosmetin. (Author)

  8. Sero-monitoring of rinderpest in the Sudan

    International Nuclear Information System (INIS)

    The indirect ELISA for the detection of antibodies to rinderpest virus has been established at the Soba Veterinary Research Laboratory along with all the necessary equipment for rinderpest sero-surveillance as envisaged under the Pan African Rinderpest Campaign (PARC). The ELISA technique was compared with the virus neutralization test and found to give comparable results. A local negative OD value was established from Sudanese cattle known not to have been in contact with rinderpest virus either through vaccination or infection. A system for the collection and transportation of sera to the central testing laboratory at Soba was established, along with a procedure for the labelling and storage of the sera at Soba to form a serum bank. A pilot sero-survey for rinderpest in some nomadic herds located in the centre of Sudan revealed that animals above three years of age had levels of immunity around 90%, those of two to three years 75% and those below two years 65%. A second survey carried out at selected dairy herds in the Khartoum area showed even higher levels of immunity (95%). These preliminary results indicate that where vaccination teams have been able to operate excellent levels of immunity have been achieved. (author). 5 refs, 2 figs, 4 tabs

    From December 2005 to June 2007, a total screening of all 1418 government primary schools in Khartoum State, Sudan, was performed to estimate ocular problems among children aged 6-15 years. We screened 671,119 children (56.7% males) for significant refractive error and other eye ailments. Ocular problems were found in 20,321 (3.03%) children. The 3 localities with highest ocular pathology were Karary (26.2%), Ummbada (21.0%) and Jabal Awlia (15.7%). The overall prevalence of refractive error was 2.19%. Myopia was found in 10,064 (1.50%) children while 4661 (0.70%) were hyperopic. Other ocular problems included vernal keratoconjunctivitis, vitamin A deficiency, microbial conjunctivitis, strabismus and corneal opacity. Only 288 (0.04%) children were diagnosed with active trachoma: 86.5% of these were from Ummbada locality, on the periphery ofthe State, where transportation facilities are poor and poverty is widespread. Overall, 99% of the eye ailments identified are either treatable or preventable. To reduce these and to achieve the goals of Vision 2020, an effective and efficient school health programme is needed.

    Surface water from Miri Lake and groundwater from around Kadugli (West-Central Sudan) obtained by means of hand-pumps was analysed for {sup 238}U, {sup 226}Ra, {sup 222}Rn, and {sup 232}Th activity concentrations. The surface water showed very low levels of radionuclide concentrations: <1.0-7.5, 8.5-16.5, <1.6, and <0.1-0.39 mBq L{sup -1} for {sup 238}U, {sup 226}Ra, {sup 222}Rn, and {sup 232}Th, respectively. Groundwater revealed a significant amount of natural radioactivity (16.1-1720, 7.7-14.3, 3000-139,000, <0.1-39 mBq L{sup -1}) respectively. The overall annual effective dose was below the WHO reference dose level of 0.1 mSv yr{sup -1} except in one groundwater sample with an associated dose of 0.7 mSv yr{sup -1}.

  12. Economic development and the allocation of petroleum products in Sudan

    International Nuclear Information System (INIS)

    The Sudanese economy has been characterized in recent years by severe energy shortages which have affected all economic activity. More than 94% of the commercial energy is imported and the level of such imports is seriously limited by the current foreign exchange crisis. However, the problem is not just one of foreign exchange; there is also the problem of utilization of resources to avoid bottleneck problems of supply. The allocation of petroleum products in Sudan has had a severe effect on all aspects of economic life. The aim of this paper is to highlight the problem and to build a model to optimize the distribution of petroleum products in order to achieve at least a minimal supply in all regions. A large linear programming model has been developed and the solution indicates that current facilities should be able to satisfy 96% of the 1986 demand, about 30% more than the actual supply. Furthermore, with a little investment in storage facilities and extra trucks, the supply could satisfy total demand in the immediate future

    Full Text Available Literature is ripe with the scholarly contributions on brand development from all aspects. The new marketing tools and techniques are introduced frequently. However, the impact social media has had on brand development is no match to traditional promotion in 4Ps. The information about Saudi Arabia is specially rare. This article based on a survey of 200 social media users on www.surveymonkey.com evaluates the role of social media in brand development in Saudi Arabia. The results from this Saudi example show that social media including Facebook and Twitter are among the most effective tool to develop a brand as compared to traditional promotional methods. It has also been found that these media are more successful in Saudi Arabia to develop the brand recall and image.

    Full Text Available Abstract Background Medical education in Saudi Arabia is facing multiple challenges, including the rapid increase in the number of medical schools over a short period of time, the influx of foreign medical graduates to work in Saudi Arabia, the award of scholarships to hundreds of students to study medicine in various countries, and the absence of published national guidelines for minimal acceptable competencies of a medical graduate. Discussion We are arguing for the need for a Saudi national medical licensing examination that consists of two parts: Part I (Written which tests the basic science and clinical knowledge and Part II (Objective Structured Clinical Examination which tests the clinical skills and attitudes. We propose this examination to be mandated as a licensure requirement for practicing medicine in Saudi Arabia. Conclusion The driving and hindering forces as well as the strengths and weaknesses of implementing the licensing examination are discussed in details in this debate.

    Ziad A. Memish

    2015-05-01

    Full Text Available Rabies is endemic in animals in the Arabian Peninsula. Although Saudi Arabia is the largest country in the Peninsula, little has been published about the rabies situation in the country. A total of 11 069 animal bites to humans were reported during 2007–2009, and 40 animals suspected of rabies were examined for rabies infection from 2005 through 2010. Results suggest that animal-related injuries in Saudi Arabia remain a public health problem, with feral dogs accounting for the majority of bites to humans and for the majority of animals found to be rabid. Over the last 10 years, no confirmed human rabies case has been reported. More detailed information about the epidemiology of animal bites and that of animal rabies in Saudi Arabia would be of great interest, notably to provide a basis on which vaccination recommendations could be made for the numerous international travellers visiting the country.

    Full Text Available Education remains one of the most important economic development indicators in Saudi Arabia. This is evident in the continuous priority of the development and enhancement of education. The application of technology is crucial to the growth and improvement of the educational system in Saudi Arabia. Introducing SMART Table technology in the Saudi Arabian education system is argued in this paper as being able to assist teachers and students in the process of accommodating both technological changes and new knowledge. SMART Tables also can enhance the level of flexibility in the educational system, thus improving the quality of education within a modern Saudi Arabia. It is crucial to integrate technology effectively and efficiently within the educational system to improve the quality of student outcomes. This study will consider the potential benefits and recommendations associated with the adoption of SMART Tables in Saudi Arabian education system.

    2013-10-01

    Several irregularly shaped craters located within Arabia Terra, Mars, represent a new type of highland volcanic construct and together constitute a previously unrecognized Martian igneous province. Similar to terrestrial supervolcanoes, these low-relief paterae possess a range of geomorphic features related to structural collapse, effusive volcanism and explosive eruptions. Extruded lavas contributed to the formation of enigmatic highland ridged plains in Arabia Terra. Outgassed sulphur and erupted fine-grained pyroclastics from these calderas probably fed the formation of altered, layered sedimentary rocks and fretted terrain found throughout the equatorial region. The discovery of a new type of volcanic construct in the Arabia volcanic province fundamentally changes the picture of ancient volcanism and climate evolution on Mars. Other eroded topographic basins in the ancient Martian highlands that have been dismissed as degraded impact craters should be reconsidered as possible volcanic constructs formed in an early phase of widespread, disseminated magmatism on Mars.

    Full Text Available Acacia senegal (L Willd. and Acacia seyal Del. are highly nitrogen-fixing and moderately salt tolerant species. In this study we focused on the genetic and genomic diversity of Acacia mesorhizobia symbionts from diverse origins in Senegal and investigated possible correlations between the genetic diversity of the strains, their soil of origin, and their tolerance to salinity. We first performed a multi-locus sequence analysis on five markers gene fragments on a collection of 47 mesorhizobia strains of A. senegal and A. seyal from 8 localities. Most of the strains (60% clustered with the M. plurifarium type strain ORS 1032T, while the others form four new clades (MSP1 to MSP4. We sequenced and assembled seven draft genomes: four in the M. plurifarium clade (ORS3356, ORS3365, STM8773 and ORS1032T, one in MSP1 (STM8789, MSP2 (ORS3359 and MSP3 (ORS3324. The average nucleotide identities between these genomes together with the MLSA analysis reveal three new species of Mesorhizobium. A great variability of salt tolerance was found among the strains with a lack of correlation between the genetic diversity of mesorhizobia, their salt tolerance and the soils samples characteristics. A putative geographical pattern of A. senegal symbionts between the dryland north part and the center of Senegal was found, reflecting adaptations to specific local conditions such as the water regime. However, the presence of salt does not seem to be an important structuring factor of Mesorhizobium species.

  19. Essays on oil and business cycles in Saudi Arabia

    Science.gov (United States)

    Aba Alkhail, Bandar A.

    This dissertation consists of three chapters. Chapter one presents a theoretical model using a dynamic stochastic general equilibrium (DSGE) approach to investigate the role of world oil prices in explaining the business cycle in Saudi Arabia. This model incorporates both productivity and oil revenue shocks. The results indicate that productivity shocks are relatively more important to business cycles than oil shocks. However, this model has some unfavorable features that are associated with both investment and labor hours. The second chapter presents a modified theoretical model using DSGE approach to examine the role of world oil prices versus productivity shocks in explaining the business cycles in Saudi Arabia. To overcome the unfavorable features of the baseline model, the alternative model adds friction to the model by incorporating investment portfolio adjustment cost. Thus, the alternative model produces similar dynamics to that of the baseline model but the unfavorable characteristics are eliminated. Also, this chapter conducts sensitivity analysis. The objective of the third chapter is to empirically investigate how real world oil price and productivity shocks affect output, consumption, investment, labor hours, and trade balance/output ratio for Saudi Arabia. This chapter complements the theoretical model of the previous chapters. In addition, this study builds a foundation for future studies in examining the impact of real world oil price shocks on the economies of key trade partners of Saudi Arabia. The results of the third chapter show that productivity shocks matter more for macroeconomic fluctuations than oil shocks for the Saudis' primary trade partners. Therefore, fears of oil importing countries appear to be overstated. As a whole, this research is important for the following reasons. First, the empirical model is consistent with the predictions of our theoretical model in that productivity is a driving force of business cycles in Saudi Arabia

  20. A new genus for a rare African vespertilionid bat: insights from South Sudan

    Full Text Available A new genus is proposed for the strikingly patterned African vespertilionid “Glauconycteris” superba Hayman, 1939 on the basis of cranial and external morphological comparisons. A review of the attributes of a newly collected specimen from South Sudan (a new country record and other museum specimens of “G.” superba suggests that “G.” superba is markedly distinct ecomorphologically from other species classified in Glauconycteris and is likely the sister taxon to Glauconycteris sensu stricto. The recent capture of this rarely collected but widespread bat highlights the need for continued research in tropical sub-Saharan Africa and in particular, for more work in western South Sudan, which has received very little scientific attention. New country records for G. cf. poensis (South Sudan and G. curryae (Gabon are also reported.

  2. Towards global Guinea worm eradication in 2015: the experience of South Sudan.

    Science.gov (United States)

    Awofeso, Niyi

    2013-08-01

    For centuries, the Guinea worm parasite (Dracunculus medinensis) has caused disabling misery, infecting people who drink stagnant water contaminated with the worm's larvae. In 2012, there were 542 cases of Guinea worm reported globally, of which 521 (96.1%) were reported in South Sudan. Protracted civil wars, an inadequate workforce, neglect of potable water provision programs, suboptimal Guinea worm surveillance and case containment, and fragmented health systems account for many of the structural and operational factors encumbering South Sudan's Guinea worm eradication efforts. This article reviews the impacts of six established Guinea worm control strategies in South Sudan: (1) surveillance to determine actual caseload distribution and trends in response to control measures; (2) educating community members from whom worms are emerging to avoid immersing affected parts in sources of drinking water; (3) filtering potentially contaminated drinking water using cloth filters or filtered drinking straws; (4) treating potentially contaminated surface water with the copepod larvicide temephos (Abate); (5) providing safe drinking water from boreholes or hand-dug wells; and (6) containment of transmission through voluntary isolation of each patient to prevent contamination of drinking water sources, provision of first aid, and manual extraction of the worm. Surveillance, community education, potable water provision, and case containment remain weak facets of the program. Abate pesticide is not a viable option for Guinea worm control in South Sudan. In light of current case detection and containment trends, as well as capacity building efforts for Guinea worm eradication, South Sudan is more likely to eradicate Guinea worm by 2020, rather than by 2015. The author highlights areas in which substantial improvements are required in South Sudan's Guinea worm eradication program, and suggests improvement strategies. PMID:23623648

  4. A review of soil conservation in the Sudan (1940-1979)

    International Nuclear Information System (INIS)

    Soil Conservation in the Sudan started in the late thirties, and in 1942 a Soil Conservation Committee was set up to report on Soil Conservation Situation. Later a Soil Conservation Section was set which developed into a department taking the responsibility of drinking water points distribution and soil and water management in rural areas. In 1974 a desert encroachment project was proposed to cover most affected areas with the help of F.A.O. Soil Conservation is an important problem in Sudan and much work is needed to tackle this problem. The application of radioisotope and radio-tracer techniques are also needed for tackling this problem. (author)

    [figure removed for brevity, see original site] This scene from the dust covered plains of eastern Arabia Terra portrays a range of geological time. Three craters at the center of the image capture some of this range. Two have the classic bowl-shape of small, relatively recent craters while the one just to the north has seen much more history. Its rim has been scoured away by erosion and its floor has been filled in by material likely of a sedimentary nature. The channels that wind through the scene may be the oldest features present while the relatively dark streaks scattered about could have been produced in the past few years or even months as winds remove a layer of dust to reveal darker material below.Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion.

The aim of this study is to explore the attitudes, beliefs and motivations of Saudis toward blood donation. Materials and Methods: The study was conducted at the Donor Centers at King Khalid University Hospital (KKUH Blood Bank and King Saud University Students Health Center, Riyadh. A self-administered questionnaire was distributed to donors (n = 517 and nondonors (n = 316, between February and June 2008. All were males. Results: Ninety-nine percent of the respondents showed positive attitude toward blood donations and its importance for patients care, and object the importation of blood from abroad. Blood donors: Ninety-one percent agree that that blood donation is a religious obligation, 91% think no compensation should be given, 63% will accept a token gift, 34% do not object to donating six times/year and 67% did not mind coming themselves to the donor center to give blood. Nondonors: Forty-six percent were not asked to give blood and those who were asked mentioned fear (5% and lack of time (16% as their main deterrents. Reasons for rejection as donors include underweight and age (71% and health reasons (19%. Seventy-five percent objected to money compensation but 69% will accept token gifts and 92% will donate if a relative/friend needs blood. Conclusion: These results reflect an encouraging strong positive attitude toward blood donation. Further future planning with emphasis on educational/publicity programs and careful organization of donor recruitment campaigns could see the dream of total voluntary nonremunerated blood donations should not take long to be true.

  15. LIVESTOCK INTEGRATION IN THE IRRIGATED AGRICULTURAL SYSTEM IN SUDAN

    Directory of Open Access Journals (Sweden)

    R.M. ELZAKI

    2011-11-01

    Full Text Available Towards the end of the 1990’s a significant decline in the areas sown to various crops and a sharp drop in productivity have been witnessed in Sudan's irrigated agriculture. At the same time feed shortages formed a main constraint on livestock production in the country. Under such a situation integration of fodder production activities within the existing crop rotations in irrigated agriculture seems plausible. Based on an optimization economic model, namely linear programming, this paper aims at investigating such prospects. The objective function in the basic model was to maximize farm returns. The analysis was based on primary data collected in the irrigated Gezira Scheme, generated through a comprehensive field survey in addition to supportive secondary data. The results showed the feasibility of introducing the fodder legume Dolichos lablab in the rotation for various reasons, such as no fertilizer needs and low demands for water and labour. A number of scenarios analyses of fodder-introducing were conducted around the results of the basic model run. All scenarios demonstrated tangible increases in farm returns, indicating that fodder cultivation would be profitable. Farmers’ income would be enhanced, either directly through fodder returns or indirectly by raising livestock products. Furthermore, fodder introduction would be conducive to reducing irrigation water requirements. Under the present and suggested changes in resource availability tomato, sorghum and cotton production would yield superior profitability to that of wheat, groundnut and onions. With the optimal production plan returns were higher than in the present situation by about 24%, while water requirement was 32% less.

  16. Radioactivity levels of basic foodstuffs and dose estimates in Sudan

    International Nuclear Information System (INIS)

    In this work a comprehensive study was carried out for the determination of different radionuclides activities in foodstuff consumed and evaluation of dose levels in different food stuffs were collected from eight States in Sudan (cereals, vegetables, meat, fruits, milk, and fermented milk, baby milk, cans, spices, additives, others). The concentrations of different radionuclides in the food samples were determined by gamma spectrometry using an HPGe detector. Radionuclides observed include: Bi-212, Bi-214, Cs-134, Cs-137, K-40, Pb-212, Pb-214, Ra-224, Ra-226, Th-228, Ac-228, TI-208, Th-232, and U-238. The activity concentration of these radionuclides were found in the following ranges: 0.51 - 19.42 Bq/Kg, 0.47 - 12.13 Bq/kg, 0.5 - 1.29 Bq/kg, 0.001 - 3.41 Bq/kg, 19.25 -2521.82 Bq/kg, 0.08 - 6.84 Bq/kg, 0.02 - 6.87 Bq/kg, 6.08 - 32.02 Bq/kg, 0.03 - 21. 53 Bq/kg, 0.92 - 26.77 Bq/kg, 0.91 - 1200 Bq/kg, 0.14 - 2.58 Bq/Kg, 0.03 - 9.65 Bq/kg, 0.03 - 9.65 Bq/kg and 0.82 - 5.27 Bq/kg respectively. High concentrations were typically found in portulaca, the lowest concentrations were found in barley and bread additives. The annual effective dose due to the different foodstuff estimated was found to be 2.78±0.44 mSv/y and 1.18±mSv/y for age categories 7-12 y and> 17y respectively. (Author)

    A survey of radiation doses to children and adults from diagnostic radiography has been carried out in seven hospitals in Sudan. In four hospitals only pediatric examinations were died. In two hospitals only adult patients were recorded and in one hospital both kinds of patients (pediatric and adults) were evaluated. For pediatric patients only chest x-ray examination was evaluated and children were divided according to age ranges: from (0-1) and 5) years for chest AP only and from (5-10) and (10-15) for chest PA. For adult patients the examinations were chest AP and PA, abdomen AP and skull AP and PA. Entrance Surface Dose SD) and the Effective Dose (E) were calculated using the Dose Cal software. The mean ESD r children, measured in p.Gy, ranged from (45-53) and (53-56) for (0-1) and (1-5) years, respectively and from (55-71) and (68-85) for (5-10) and (10-15) years, respectively. In two of le pediatric hospitals the mean ESD values were greater than the CEC Reference Dose Levels. In El bulk and Si nar hospitals the values ranged from 167-261 and 186-308 μGy for the age ranges (0-1) and (1-5) respectively and 167-194 and 279-312 μGy for the age ranges of (5-10) and (10-15) respectively. For adult patients the ESD and E dose values evaluated in Alfisal hospital presented values comparable with the CEC Reference Dose Level. However for Alshorta hospital the values were higher for the chest AP and PA with results for ESD 0.446 and 0.551 mGy respectively

    Invited Paper Forty years ago Colin Renfrew declared that "every archaeological problem starts as a problem in geoarchaeology" (Renfrew, 1976 p. 2). With this assertion in mind, this paper draws upon the findings from field research in two sectors of the Nile Valley of Northern Sudan dedicated to the exploration of human-environment interactions during the middle and late Holocene. This part of the Nile corridor contains a rich cultural record and an exceptionally well preserved Holocene fluvial archive. A distinctive feature of these records is the variety of evidence for interaction between desert and river over a range of spatial and temporal scales. This interaction presented both challenges and opportunities for its ancient inhabitants. This paper will present evidence for large-scale landscape changes driven by shifts in global climate. It will also show how we have integrated the archaeological and geological records in the Northern Dongola Reach and at Amara West - where long-term field projects led by archaeologists from the British Museum have recognised the importance of a sustained commitment to interdisciplinary research to achieve a fully integrated geoarchaeological approach across a range of scales. The former project is a large-scale landscape survey with multiple sites across an 80 km reach of the Nile whilst the latter has a strong focus on a single New Kingdom town site and changes in its environmental setting. By combining multiple archaeological and geological datasets - and pioneering the use of OSL dating and strontium isotope analysis in the Desert Nile - we have developed a new understanding of human responses to Holocene climate and landscape change in this region.

  19. Pathogenesis and immunology of ruminant schistosomiasis in the Sudan

    International Nuclear Information System (INIS)

    Schistosoma bovis in the Kosti area (Sudan) was almost 90% in cattle up to 2 years old but fell to around 30% by 10 years of age. Infection incidence followed a markedly seasonal pattern of transmission. Infected animals either lost weight or gained less weight than controls. This was associated with the development of severe anaemia and hypoalbuminaemia, which in turn were due to massive blood and plasma losses through the gut mucosa. The epizootiological work suggested that cattle can acquire resistance to S. bovis as a result of repeated field infections. This was tested by artificially challenging field-infected cattle, together with animals of similar age and breed from a non-enzootic area. Animals reared in an enzootic environment clearly become solidly resistant to a cercarial challenge sufficient to cause fatal disease in cattle from non-enzootic areas. The mechanisms responsible for this phenomenon are being studied. Immunization with irradiated vaccines was tested in the laboratory. A marked reduction in the faecal egg counts, worm burdens, tissue egg counts and clinical manifestations of the vaccinated compared with non-vaccinated cattle and sheep indicated significant protection. Vaccination efficacy was also tested under field conditions. A group of calves was immunized with irradiated S. bovis schistosomula and a second group served as controls. These animals were released into the field in the enzootic area of Kosti and followed up for 10 months. The results showed 80% reduction in the faecal egg counts and about 70% protection in terms of reduced worm and tissue egg counts in vaccinated compared with non-vaccinated calves. Further evidence of resistance was shown by the lower mortality rate in the former animals. Vaccination against schistosomiasis can be of practical benefit to livestock

  20. Marriage pattern in the Sudan and its interrelation with fertility.

    Science.gov (United States)

    Khalifa, M

    1986-06-01

    The marriage pattern is an aspect of the social, economic and cultural conditions of a population. Recent changes taking place in Sudanese society are associated with a slight increase in the mean age at 1st marriage for females. Demographic and economic factors may be responsible for the change. The migration of Sudanese males at marriageable ages to the rich oil countries resulted in an unbalanced sex ratio which may be responsible for a marriage squeeze. The same effect is taking place as a result of high rural-urban migration. Increasing economic pressure has created a need for employment of women outside the home. This phenomenon has helped to change the role concept of both sexes and provided an alternative to early marriage. There has been a remarkable expansion of women's education in the Sudan since independence in 1956. Economic pressure has also affected the age at marriage by making marriage less feasible. Financial preparations for a marriage, in both urban and rural areas, appear to exert a significant pressure towards marital postponement. Postponement of marriage is associated with more marital stability and reductions in the amount of lost reproductive time. Also, the fertility of the women who marry late is only slightly less than that of those who marry young. Late marriers catch up with those who married young and the slight excess experienced by the young marriers takes place towards the end of the reproductive life. Changes in the Sudanese birth rate are not expected to accompany the process of development. The current level and effectiveness of birth control are not enough to affect fertility especially as it is not aimed at reducing the number of births. Reductions in the level of Sudanese fertility can be achieved only through improvement of the effectiveness of family planning programs. PMID:12280549

  1. Computed tomography quality control (QC) status in Sudan

    International Nuclear Information System (INIS)

    Quality control (QC) tests were performed to eleven computed tomography (CT) scanners in Khartoum, the capital of Sudan. The work was performed as part of the authorization procedure, which was requested on behalf of the Radiation Protection Technical Committee (RPTC), the regulatory authority in Sudan. The purpose of the present study is to address malfunctioning of CT scanners and define its impact on image quality and state to which extent it can affect the diagnostic information gained from undergoing CT scanning. For the sake of achieving a thorough study of this issue, the relevant hospital staff - technologists, radiologists and medical engineers - were involved in this study through discussion and questionnaire. The measurements were performed in accordance with IEC and ImPACT CT quality control protocols. The following tests were involved: average CT number for water, CT number uniformity, noise, high contrast resolution, low contrast resolution, slice thickness, and CT number linearity. All scanners under study were tested, different performance phantoms were used as each manufacturer has its own phantom but all are testing same parameters, however each with its own method, e.g. for spatial resolution some using bar pattern while others using drilled holes, but both reflect the same result when expressed in terms of limited resolution in millimetres. The primary analysis of collected data revealed that more than 60% of scanners under study were installed within the last three years. Nevertheless, the dominant feature among all scanners was the absence of quality assurance and quality control programmes - no acceptance testing is performed upon installation of the equipment, no designated personnel are available for quality control measurements, no preventive maintenance and regular calibration are being conducted. In some units, no performance phantoms were supplied with the scanner, and generally, the importance of quality control is not highly

    The biomedical research sector in Saudi Arabia has recently received special attention from the government, which is currently supporting research aimed at improving the understanding and treatment of common diseases afflicting Saudi Arabian society. To build capacity for research and training, a number of centres of excellence were established in different areas of the country. Among these, is the Centre of Excellence in Genomic Medicine Research (CEGMR) at King Abdulaziz University, Jeddah, with its internationally ranked and highly productive team performing translational research in the area of individualized medicine. Here, we present a panorama of the recent trends in different areas of biomedical research in Saudi Arabia drawing from our vision of where genomics will have maximal impact in the Kingdom of Saudi Arabia. We describe advances in a number of research areas including; congenital malformations, infertility, consanguinity and pre-implantation genetic diagnosis, cancer and genomic classifications in Saudi Arabia, epigenetic explanations of idiopathic disease, and pharmacogenomics and personalized medicine. We conclude that CEGMR will continue to play a pivotal role in advances in the field of genomics and research in this area is facing a number of challenges including generating high quality control data from Saudi population and policies for using these data need to comply with the international set up.

    Many studies that research bio-nanocomposites utilize techniques that involve the dispersion of strengthening components like silica, metal and metal oxides through a host biopolymer matrix. The biggest success factor for the bio-nanocomposite is having a smooth integration of organic and inorganic phases. This interattraction between the surfaces of inorganic particles and organic molecules are vital for good dispersion. In this study, a novel biodegradable antibacterial material was developed using gum arabic from Senegalia senegal (stabilizer), silica (structure reinforcer) and zero valent iron particles. Silica particles work to not only strengthen the mechanical properties of the Senegalia senegal but also prevent the accumulation of ZVI nanoparticles due to attraction between hydroxyl groups and FeO. The gum arabic/Fe-SiO2 bio-nanocomposite showed effective antibacterial property against the Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. Using Scanning electron microscopy, homogeneous dispersion and uniform particle size was viewed in the biopolymer. X-ray diffraction studies of iron particles organization in Senegalia senegal also showed that the main portion of iron was crystalline and in the form of FeO and Fe0. X-ray photoelectron spectroscopy was used to evaluate the chemical composition of the surface but no appreciable peak was measured for the iron before Ar etching. These results suggest that the surface of iron nanoparticles consist mainly of a layer of iron oxides in the form of FeO. Thermal gravimetric analysis was used to determine the thermal stability and absorbed moisture content.

  18. Early Infant Male Circumcision in Cameroon and Senegal: Demand, Service Provision, and Cultural Context

    ABSTRACT Background: Male circumcision is almost universal in North and West Africa, and practiced for various reasons. Yet there is little documentation on service delivery, clinical procedures, policies, and programmatic strategies. The United Nations Children’s Fund (UNICEF) commissioned country program reviews in 2014 to shed light on the delivery of male circumcision services for infants in Cameroon and Senegal. Methods: We conducted a policy desk review, key informant interviews, and focus group discussions at health centers and in communities. Between December 2014 and January 2015, we conducted 21 key informant interviews (13 with regional and district officers, 5 with national officers, and 3 with UNICEF officials) and 36 focus group discussions (6 with men, 6 with women, 12 with adolescent boys, and 12 with service providers). Some of the men and women were parents of the adolescents who participated in the focus group discussions. In the French-speaking areas, the focus group discussions were conducted in French through an accredited translator, audio recorded, and transcribed into English. Results: All of the facilities we visited in Cameroon and Senegal offer medical male circumcision, with 10 out of 12 performing early infant male circumcision (EIMC) routinely. Neither country has policies, guidelines, or strategies for EIMC. The procedure is done mainly by untrained service providers, with some providers using modern circumcision devices. There are no key messages on EIMC for families; the increasing demand for EIMC is led by the community. Conclusion: Despite the absence of national policies and strategies, EIMC is routinely offered at all levels of the health care system in Cameroon and Senegal, mainly by untrained service providers. Improving circumcision services will require guidelines for EIMC and improvements in training, equipment, supply chains, recordkeeping, and demand creation. PMID:27413080

  19. Reconstructing Colonization Dynamics of the Human Parasite Schistosoma mansoni following Anthropogenic Environmental Changes in Northwest Senegal.

    Frederik Van den Broeck

    2015-08-01

    Full Text Available Anthropogenic environmental changes may lead to ecosystem destabilization and the unintentional colonization of new habitats by parasite populations. A remarkable example is the outbreak of intestinal schistosomiasis in Northwest Senegal following the construction of two dams in the '80s. While many studies have investigated the epidemiological, immunological and geographical patterns of Schistosoma mansoni infections in this region, little is known about its colonization history.Parasites were collected at several time points after the disease outbreak and genotyped using a 420 bp fragment of the mitochondrial cytochrome c oxidase subunit 1 gene (cox1 and nine nuclear DNA microsatellite markers. Phylogeographic and population genetic analyses revealed the presence of (i many genetically different haplotypes at the non-recombining mitochondrial marker and (ii one homogenous S. mansoni genetic group at the recombining microsatellite markers. These results suggest that the S. mansoni population in Northwest Senegal was triggered by intraspecific hybridization (i.e. admixture between parasites that were introduced from different regions. This would comply with the extensive immigration of infected seasonal agricultural workers from neighboring regions in Senegal, Mauritania and Mali. The spatial and temporal stability of the established S. mansoni population suggests a swift local adaptation of the parasite to the local intermediate snail host Biomphalaria pfeifferi at the onset of the epidemic.Our results show that S. mansoni parasites are very successful in colonizing new areas without significant loss of genetic diversity. Maintaining high levels of diversity guarantees the adaptive potential of these parasites to cope with selective pressures such as drug treatment, which might complicate efforts to control the disease.

  20. Stable isotopes for body composition and breast milk intake assessments: IAEA initiatives in Ghana and Senegal

    International Nuclear Information System (INIS)

    Body composition can be measured by various techniques. However, The only way in which lean body mass and fat body mass can be measured accurately in free-living human subjects is to use a kinetic method with water labelled with 2H and or 18O. Known as the 'stable isotope dilution method' this procedure is now accepted worldwide. In addition, This technique has been validated to assess infant milk intake. Indeed, the dose-to-mother isotope dilution method measures breast milk output and mother's body composition with minimum interference on the lactation process.The IAEA Technical Cooperation projects in Senegal and Ghana were aimed at estimating breast milk output and mother's body composition by deuterium dilution methods among lactating mothers, who were the beneficiaries of the National Supplementary Feeding Programme. A dose of deuterium oxide was orally administrated to the mothers and saliva samples were collected from both the babies and the mothers before and after the administration of the dose. Enrichment of the saliva samples was measured by a fast, easy and less expensive method, which uses a Fourier Transformed Infrared Spectrometer (FTIR). In Senegal, the study has been conducted on 206 women paired with their children and 1876 saliva samples have been analysed in duplicate. In Ghana, 150 paired women with their children have been selected for the study and 2100 saliva samples have been analysed. Following results were obtained after a 3 months supplementary feeding: There is a significant increase in mother's lean body mass (41.35Kg ± 5.00) vs (34.63Kg ± 6.09) respectively in supplemented and non-supplemented mothers in Ghana. And, (40Kg±4) vs (37Kg±4) respectively in supplemented and non-supplemented mothers in Senegal; Breast Milk volume increased significantly in Ghana's study (1050 ml ±280) vs (850 ml± 150).

    This paper investigates the impact of female employment on fertility in two urban contexts in sub-Saharan Africa: Dakar (Senegal) and Lomé (Togo). The hypothesis that wage employment and maternal obligations are incompatible seems to be corroborated in Lomé, where women are likely to consider work as a legitimate alternative to their role as a mother or spouse. Being involved in economic activity is a real option and can therefore impact upon their reproductive life. By contrast, in Dakar wor...

    At the crossroads between Africa and Eurasia, Arabia is necessarily a melting pot, its peoples enriched by successive gene flow over the generations. Estimating the timing and impact of these multiple migrations are important steps in reconstructing the key demographic events in the human history. However, current methods based on genome-wide information identify admixture events inefficiently, tending to estimate only the more recent ages, as here in the case of admixture events across the Red Sea (~8-37 generations for African input into Arabia, and 30-90 generations for "back-to-Africa" migrations). An mtDNA-based founder analysis, corroborated by detailed analysis of the whole-mtDNA genome, affords an alternative means by which to identify, date and quantify multiple migration events at greater time depths, across the full range of modern human history, albeit for the maternal line of descent only. In Arabia, this approach enables us to infer several major pulses of dispersal between the Near East and Arabia, most likely via the Gulf corridor. Although some relict lineages survive in Arabia from the time of the out-of-Africa dispersal, 60 ka, the major episodes in the peopling of the Peninsula took place from north to south in the Late Glacial and, to a lesser extent, the immediate post-glacial/Neolithic. Exchanges across the Red Sea were mainly due to the Arab slave trade and maritime dominance (from ~2.5 ka to very recent times), but had already begun by the early Holocene, fuelled by the establishment of maritime networks since ~8 ka. The main "back-to-Africa" migrations, again undetected by genome-wide dating analyses, occurred in the Late Glacial period for introductions into eastern Africa, whilst the Neolithic was more significant for migrations towards North Africa.

  10. Subacute thyroiditis in Western Saudi Arabia

    International Nuclear Information System (INIS)

    The aim of this study is to assess the clinical presentation of 23 patients with subacute thyroiditis (SAT) and the diagnostic value of radionuclear scan. This is a cohort study, which consists of 23 patients with a suspected diagnosis of subacute thyroiditis. The study was carried out in the Endocrinology Clinic, King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia between July 2002 and July 2004. Medical charts including age, gender, clinical presentation, systemic symptoms and clinical examination of the thyroid gland were reviewed. Laboratory data included white blood count and its differential count, erythrocyte sedimentation rate (ESR), thyroid function test and thyroid antibodies. The radionuclear scan results were also noted. The mode of therapy provided to patients and the outcome of the treatment during a follow up period of 2 years was reported. Twenty-three adult patients with subacute thyroiditis (15 females and 8 males with a female to male ratio of 1.9:1) were reviewed over a 2-year period. The mean age was 35.8+9.2 years. Eighteen patients (78%) had an upper respiratory tract infection at the initial clinical presentation. Twenty patients (87%) visited an Ear, Nose and Throat specialist for sore throat and abnormal sensation in the throat at least 2 weeks before presentation to the endocrinologist. Two patients were admitted to a medical unit with a diagnosis of fever of unknown origin for 4 weeks. All patients had an elevated free thyroxine (35.7+19.8 pmol/L) and suppressed thyroid-stimulating hormone (TSH) (0.043+0.065IU). The radionuclear scan showed either no uptake at all in 12 patients or minimal uptake in 11 patients (0.32+0.55%). Eight patients (35%) received prednisolone therapy alone with an average dose of 30-40 mg daily for 7-8 days; 7 patients (30%) were treated with non-steroidal anti-inflammatory drugs (NSAIDs) only.

    The signing of the Comprehensive Peace Agreement (CPA) in Sudan has created a new opportunity for peace. Approaches to food security must now be reoriented based on the agro-ecological diversity in Sudan. WFP is in a unique position to catalyse an approach to food security that meets immediate needs and contributes to long-term recovery, in collaboration with the Government of National Unity (GNU) and the Government of South Sudan (GOSS). Aggregate food production in Sudan has increased in the past decade. At sub-regional levels, however, many areas remain food insecure. Major research must be undertaken to identify optimum levels of food production and barriers to access to food at sub-regional levels as a first step towards linking deficit areas with areas of surplus. Initiatives must also be undertaken to facilitate increased integration between sub-regions. Increased sub-regional linkages could ensure more efficient delivery of food in the short term as well as recovery and economic growth in the long term. PMID:17349002

    2015-05-01

    The effects of development and the uncertainty of a changing climate in eastern Africa pose myriad challenges for water managers along the Blue Nile. Sudan's large irrigation potential, hydroelectric dams, and prime location within the basin mean that Sudan's water management decisions will have great social, economic and political implications for the region. At the same time, Sudan's water use options are constrained by tradeoffs between upstream irrigation developments and downstream hydropower facilities as well as by the country's commitments under existing or future transboundary water sharing agreements. Here, we present a model that can be applied to evaluate optimal allocation of surface water resources to irrigation and hydropower in the Sudanese portion of the Blue Nile. Hydrologic inputs are combined with agronomic and economic inputs to formulate an optimization model within the General Algebraic Modeling System (GAMS). A sensitivity analysis is performed by testing model response to a range of economic conditions and to changes in the volume and timing of hydrologic flows. Results indicate that changing hydroclimate inputs have the capacity to greatly influence the productivity of Sudan's water resource infrastructure. Results also show that the economically optimal volume of water consumption, and thus the importance of existing treaty constraints, is sensitive to the perceived value of agriculture relative to electricity as well as to changing hydrological conditions.

  9. Determination of polonium 210 in different types of tobacco consumed in Sudan

    International Nuclear Information System (INIS)

    The carcinogenic effect of 210 Po with respect to lung cancer is an important problem in many countries with very high cigarette consumption. Sudan is one of the consumptions of cigarettes in the world. The aim of this study was the determination polonium-210 in different parts of tobacco plant comes from China and Brazil consumed in cigarette in Sudan and determination of 210 Po in five most frequently smoked brands more consumption in Sudan. The annual committed effective dose from cigarette was determined and comparison with other results reported in literature. The tobacco plant (leaves and root) for analysis were collected from Haggar factory in Sudan and another brand were collected randomly from markets, only the most popular one was chosen for analysis (Bringi, Lord, Winner, Goal, Benson). The polonium-210 activity was measured on an alpha-spectrometer equipped with semiconductor surface barrier silicon detectors after spontaneously plated onto asilver disc from hydrochloric acid medium. Polonium samples were measured for 2-3 days. The accuracy and precision of radiochemical method were evaluated using (IAEA-326). The values of activity concentration of 210 Po found in cigarettes consumed in Sudan are within of the range of values found in the literature. The 210 Po presented concentration in different brands ranging from 22.8 to 51.6 Bqkg-1(average 36.54 Bq kg-1). The activity concentration of 210 Po in popular brand cigarette tobacco is higher than that in fine brand cigarette tobacco. Found the highest concentration in the raw material compared to the final product is attributed that to the import, storage and manufacturing processes. Activity determination indicates those cigarettes consumed in Sudan are comparable to the values reported in China and Brazil that the raw material comes from these two countries. The polonium is non-uniformly distributed within the tobacco plants analyzed in this study, the highest levels were found in the leaves

    Full Text Available To characterize hepatitis C virus (HCV epidemiology and assess country-specific population-level HCV prevalence in four countries in the Middle East and North Africa (MENA region: Djibouti, Somalia, Sudan, and Yemen.Reports of HCV prevalence were systematically reviewed as per PRISMA guidelines. Pooled HCV prevalence estimates in different risk populations were conducted when the number of measures per risk category was at least five.We identified 101 prevalence estimates. Pooled HCV antibody prevalence in the general population in Somalia, Sudan and Yemen was 0.9% (95% confidence interval [95%CI]: 0.3%-1.9%, 1.0% (95%CI: 0.3%-1.9% and 1.9% (95%CI: 1.4%-2.6%, respectively. The only general population study from Djibouti reported a prevalence of 0.3% (CI: 0.2%-0.4% in blood donors. In high-risk populations (e.g., haemodialysis and haemophilia patients, pooled HCV prevalence was 17.3% (95%CI: 8.6%-28.2% in Sudan. In Yemen, three studies of haemodialysis patients reported HCV prevalence between 40.0%-62.7%. In intermediate-risk populations (e.g.. healthcare workers, in patients and men who have sex with men, pooled HCV prevalence was 1.7% (95%CI: 0.0%-4.9% in Somalia and 0.6% (95%CI: 0.4%-0.8% in Sudan.National HCV prevalence in Yemen appears to be higher than in Djibouti, Somalia, and Sudan as well as most other MENA countries; but otherwise prevalence levels in this subregion are comparable to global levels. The high HCV prevalence in patients who have undergone clinical care appears to reflect ongoing transmission in clinical settings. HCV prevalence in people who inject drugs remains unknown.

    Structural and maturation studies in the northwest of the Muglad Basin, Sudan showed a thick sedimentary section up to 9000 m in the deep sub-basins and an average of about 6000 m in the Sharaf-Abu Gabra Ridge. The isopach map of the Lower Cretaceous Abu Gabra-Sharaf formations, which contain source rocks, showed a thickness of sedimentary section between 2000 and 5000 m. The burial history showed high subsidence rates during the first rifting phase with relatively low subsidence rates during the following two phases in this part of the basin. Significant erosion of the sedimentary section occurred in the ridge area during Miocene and Cenomanian-Albian times. The geothermal gradients in the modelled wells range between 18 and 27.5 °C/km corresponding to the relatively wide range of present day heat flow of between 37 and 63 mW/m 2, averaging 50 mW/m 2. Heat flow history curves consistent with vitrinite reflectance data were adopted with elevated high heat flow (75 mW/m 2) during the first rifting phase followed by minor peaks (average 60 mW/m 2) during the second and the third rifting phases. Application of a kinetic vitrinite maturation model resulted in a present day oil window between 2000 and 4500 m. The source rock of the Abu Gabra (AG) and Sharaf (SH) formations, which has an average total organic carbon of 1.0% and hydrogen index (HI) of 280, was modelled for hydrocarbon generation. The section was divided into four layers; AG-1 (Albian), AG-2 (Aptian), SH-1 (Barremian) and SH-2 (Neocomian). Conditions for hydrocarbon generation are present throughout the Sharaf formation and in AG-2. The generation model suggests an average generation amount of 4 mgHC/g rock in the lower three modelled layers with a timing range between 120 Ma and the present. Total calculated oil volume is about 370 US billion bbls and the expected volume expelled and migrated (40%) is 150 US billion bbls. The total gas expelled and migrated (90%) is 1600 US trillion cu ft. Retention of

  12. Demographic intermediation between development and population redistribution in Sudan.

    Science.gov (United States)

    Farah, A A

    1983-12-01

    This article analyzes the causes of population distribution in various geographical regions of Sudan. Population distribution is a function of fertility, mortality, and net migration. These variables are primarily caused by changes in socioeconomic factors prevailing in each area. The analysis shows that the population distribution among the geographical regions is primarily shaped by the differential development actions during the last 2 decades. The regional variability of population growth and density largely reflects regional development. Provinces are classified into 3 groups according to stages of population growth. The 1st group is composed of the 3 southern provinces, characterized by the highest mortality, lowest fertility, a marginal volume of net migration, and the lowest overall population growth rate during the last 2 decades. These are the poorest provinces in terms of per capita income, education, communication, and health measures. The 2nd group comprises Dafur, Kordofan, Northern and Red Sea Provinces, which generally reflect an intermediate stage in the demographic evolution in the country. Fertility is positively correlated and mortality is inversely related to the level of per capita income, resulting in an inverse relationship between the 2 vital rates. Therefore, the natural growth will probably increase. However, there are also areas of out-migration. Their future population growth and density will depend on the extent to which the out-migration will affect their natural growth rates. The 3rd group is composed of Khartoum, Blue Nile and Kassala provinces. They have the highest fertility, lowest mortality and highest volume of in-migration. Therefore, they witnessed the highest population growth rate and population density during the period. They encompass the largest urban centers with the highest degree of modernization and family planning activities. It is postulated that their future fertility and mortality rates will decline in varying

  16. Financing energy SMEs in Ghana and Senegal: Outcomes, barriers and prospects

    International Nuclear Information System (INIS)

    The article presents the findings of primary research carried out in Ghana and Senegal, which revisited the main assumptions behind the African Rural Energy Enterprise Development (AREED) initiative (2002–2012), and other donor-backed programmes, designed to promote small and medium-sized energy enterprises (energy SMEs). These assumptions were (1) that the lack of affordable local financing presented the most significant barrier to setting up and expanding energy SMEs, and (2) that these barriers would be overcome by a ‘demonstration effect’ whereby successful businesses, supported by donor-backed programmes, could in turn influence the commercial financial sector to invest in energy SMEs, thus triggering a virtuous circle of growth and profitability. - Highlights: • Analysis of the AREED ‘demonstration effect’ in Senegal and Ghana. • Commercial financial backing for SMEs remains a serious challenge for entrepreneurs. • Structural issues that increase the financial risk of investing in energy SMEs. • High transaction costs of investing in SMEs. • Longer supply chains and slower pay-back periods for capital-intensive technologies

  17. Analysis of the cost and benefit of bovine artificial insemination in Senegal

    International Nuclear Information System (INIS)

    A field survey was conducted to determine the rate of success of artificial insemination (AI) in cattle in Senegal and the benefit obtained by raising the resulting F1 crossbred heifers. The area selected was the first one in which a public AI programme was implemented. A questionnaire was administered to farmers regarding the management of cattle and the costs and benefits of the AI service. Out of 207 inseminations, 80 were successful, resulting in a calving rate of 38.6%. The F1 crossbreds produced 8.9 litres of milk per day, compared with 2 litres per day for the local breeds, and had a lactation length of 13 months. The death rate for crossbred calves during the first year of life was 22.5%. The total cost for an AI was FCFA 48 143 per cow, and was mostly subsidized by the Senegal State. The net profit for the producer was FCFA 35 (Euro 1 = approx. FCFA 660) per litre of milk produced by a crossbred. The proportional costs of the different components of the AI service were 12.5% for the purchase and conservation of semen, 21.9% for the synchronization of heats and 53% for provision of the AI service. The study identified weaknesses and limitations in the dairy production system. Future actions are recommended to improve the results of AI, to reduce the costs and to increase the benefits to producers. (author)

  18. The Role of Productive Water Use in Women’s Livelihoods: Evidence from Rural Senegal

    Directory of Open Access Journals (Sweden)

    Emily van Houweling

    2012-10-01

    Full Text Available Enhancing livelihoods and promoting gender equity are primary goals of rural development programmes in Africa. This article explores the role of productive water use in relation to these goals based on 1860 household surveys and 15 women’s focus groups conducted in four regions of Senegal with small-scale piped water systems. The piped systems can be considered 'domestic plus' systems because they were designed primarily for domestic use, and also to accommodate small-scale productive uses including livestock-raising and community-gardening. This research focuses on the significance of productive water use in the livelihood diversification strategies of rural women. In Senegal, we find that access to water for productive purposes is a critical asset for expanding and diversifying rural livelihoods. The time savings associated with small piped systems and the increased water available allowed women to enhance existing activities and initiate new enterprises. Women’s livelihoods were found to depend on productive use activities, namely livestock-raising and gardening, and it is estimated that one half of women’s incomes is linked to productive water use. While these findings are largely positive, we find that water service and affordability constraints limit the potential benefits of productive water use for women and the poorest groups. Implications for targeting women and the poorest groups within the domestic plus approach are discussed.

  19. Population structure of newly established Anopheles funestus populations in the Senegal River basin using paracentric chromosomal inversions.

    Anopheles funestus is one of the major vectors of malaria in sub-saharan Africa. Because of several cycles of recurrent drought events that have occurred in the sahelian zone, this species had disappeared from this area since the 1970s following a disappearance of its specific breeding sites. Its comeback was, however, recently observed particularly in the Senegal River basin following the implementation of two dams. Because the implementation of hydro-agricultural and irrigation settings are suspected to be involved in the reestablishment of An. funestus populations and that paracentric inversions are involved in the adaptation to various environments, the present study was undertaken in 3 villages of the Senegal River basin (Keur Mbaye, Mbilor and Gankette Balla), (i) to study the chromosomal polymorphism of the newly established An. funestus populations in the Senegal River basin using paracentic inversions from ovarian nurse cells and (ii) their relationship with other populations of this species located in different environmental contexts (Dielmo in sudanian zone, Sankagne and Kouvar in northern sudano-guinean zone and Ngari in southern sudano-guinean zone) in order to know the key factors leading to their reestablishment in this area. Our results showed that the newly established An. funestus populations' exhibit low level of chromosomal polymorphism with two chromosomal inversions (the fixed 2Rs and the polymorphic 3La) out of the 9 paracentric inversions described up to now in An. funestus in Senegal. At population level, no significant deviation from Hardy-Weinberg equilibrium was observed for almost all inversions. Furthermore, significant genetic differentiation was revealed between the populations from the Senegal River basin and those from the sudanian and southern sudano-guinean zones and was not linked to geographical distance. However, the populations from the Senegal River basin were close or slightly differentiated to those from the northern

    Full Text Available Mesquite has received increased consideration at public and social levels. It is perceived as valuable in its role in forest products and environmental concern. The principal objective of the present study was to evaluate the perception of local communities towards using mesquite products as compared to indigenous species. The study investigated the main factors affecting mesquite spread and reviewed the state of knowledge about the extent of mesquite invasion in forest reserves in Kassala State in eastern Sudan. The aim was also to provide guidelines for management and control of mesquite tree and to assess the impact of education level on the person's perception towards the tree and its products. In a cross-sectional survey, a total of 431 farmers were interviewed using several data collection methods including interviews, informal discussions and questionnaires. Previous inventories and surveys were based on ground and aerial techniques. Cross tabulations of selected variables were created as a support to fulfill the tests of significant internal differences between different variables among different categories of respondents. Chi-square tests were used to disaffiliate aspects related to local understanding and external influences. In the present study, 24 cross tabulated actions were tested by chi-square to provide in numerical figures the level of similarities or differences between categories of users. A summary of the chi-square test values were arranged in ascending order ranging from chi-square value of 9.436 to chi-square value of 245.55. An attempt was made to elucidate the socioeconomic factors, to evaluate the attitude of local communities towards mesquite eradication and replacement. The results of the study revealed that mesquite provides benefits, but also causes problems. According to the perception of the respondents, mesquite provides a wide range of products and services to local communities that make the species valuable

  5. Effects of climate change on agriculture and environment in the semi-arid tropic - with Senegal as an example

    International Nuclear Information System (INIS)

    Some of the likely effects of the climate changes, projected by IPCC, on agriculture and environment in Senegal have been described. If rainfall does indeed increase, as suggested by the IPCC WG1 report, reversal of negative trends in vegetation productivity, associated with the droughts of the last decades on the 20th Century, will be expected to occur. Present tendencies towards encroachment of crop cultivation on rangelands will be reinforced. These effects are likely to be economically beneficial to Senegal, yet their importance will be determined by the extent to which other factors will counteract them. With respect to crop and rangeland productivity nutrient-limitations will become increasingly important if not avoided by increased application of mineral fertilizers which is presently uneconomical. If rainfall does not increase significantly, the probable higher temperatures will tend to decrease crop and rangeland productivity, due to an increase in evapotranspirations rates. Also, the competition for water resources is likely to be intensified, especially the water resources of the Senegal River which are shared by four countries. The greater international focus on climate issues also affects Senegal by putting an economic value on carbon storage and avoidance of emissions of greenhouse gases. Current trends of expanding agriculture into rangelands and woodland areas imply a reduction in the storage of carbon in vegetation and soils. The use of fire as a natural resource management practice may have significant impacts on emissions, and may therefore be affected by emission policies. The challenge for Senegal will be to develop policies and preparedness in order to adapt to the changes that are likely to come. Presently, government policies are only to a very limited extent taking the projected change into consideration. (LN)

    2015-03-01

    Saudi Arabia is the third-largest Arab country with a moderate annual burden of tuberculosis. However, tuberculosis (TB) is among several infectious diseases that have not been brought under control, despite the government's considerable efforts. This is clearly evidenced by the ongoing transmission of several imported and indigenous clades of Mycobacterium tuberculosis. In addition, the country faces the threat from rising proportions of extrapulmonary TB, non-tuberculous mycobacterial infections, and drug resistance. Furthermore, the country falls behind the global targets set by World Health Organization for the success rate of TB treatment. The country needs more population-based research studies, centralized and easily accessible clinical data registries, and centralized research and diagnostic facilities.

    We studied knowledge of nutritional needs during pregnancy and lactation in 150 pregnant Saudi women at three primary health care centers in Riyadh, Saudi Arabia. We used an interview schedule to collect data regarding the women's knowledge and to determine the effects of certain independent variables on the knowledge scores. Green et al.'s (1980) PRECEDE model provided the theoretical framework for the study. Descriptive statistics, t test, and chi-square methods were used to analyze the data. The majority of the women had poor nutrition knowledge scores, with no significant differences among the three centers. A positive relationship was found between knowledge score and educational level. Negative relationships were found between knowledge score and number of pregnancies, number of deliveries, and number of living children. The findings have several implications for efforts to improve the health status of women in Saudi Arabia. PMID:8002417

    Sudan I, II, III and IV dyes are banned for use as food colorants in the United States and European Union because they are toxic and carcinogenic. These dyes have been illegally used as food additives in products such as chilli spices and palm oil to enhance their red colour. From 2003 to 2005, the European Union made a series of decisions requiring chilli spices and palm oil imported to the European Union to contain analytical reports declaring them free of Sudan I–IV. In order for the USFDA to investigate the adulteration of palm oil and chilli spices with unapproved colour additives in the United States, a method was developed for the extraction and analysis of Sudan dyes in palm oil, and previous methods were validated for Sudan dyes in chilli spices. Both LC-DAD and LC-MS/MS methods were examined for their limitations and effectiveness in identifying adulterated samples. Method validation was performed for both chilli spices and palm oil by spiking samples known to be free of Sudan dyes at concentrations close to the limit of detection. Reproducibility, matrix effects, and selectivity of the method were also investigated. Additionally, for the first time a survey of palm oil and chilli spices was performed in the United States, specifically in the Washington, DC, area. Illegal dyes, primarily Sudan IV, were detected in palm oil at concentrations from 150 to 24 000 ng ml−1. Low concentrations (adulteration. PMID:26824489

    Highlights: • A lipophilic sensor layer was applied to enzymatically grown SERS substrates. • Sudan III molecules could be detected in presence of water-insoluble competitors. • The carcinogenic food dye Sudan III was detected in a relevant concentration range. • Multivariate statistics allows quantitative measurements of Sudan III. • Sudan III contaminations were successfully detected out of spiked paprika powder. - Abstract: Food safety is a topic of great importance for our society which places high demands on analytical methods. Surface enhanced Raman spectroscopy (SERS) meets the requirements for a rapid, sensitive and specific detection technique. The fact that metallic colloids, one of the most often used SERS substrates, are usually prepared in aqueous solution makes the detection of water-insoluble substances challenging. In this paper we present a SERS based approach for the detection of water-insoluble molecules by applying a hydrophobic surface modification onto the surface of enzymatic generated silver nanoparticles. By this approach the detection of the illegal water-insoluble food dyes, such as Sudan III in presence of riboflavin, as water-soluble competitor, is possible. Moreover, we demonstrate the usability of this kind of SERS substrates for determination of Sudan III out of spiked paprika extracts.

  12. Human security in Sudan: The report of a Canadian Assessment Mission

    International Nuclear Information System (INIS)

    In October 1999 the Minister of Foreign Affairs and the Minister for International Co-operation announced the creation of an assessment mission to Sudan to examine allegations about human rights abuses, including the practice of slavery and to investigate and report on alleged link between oil development and human rights violations, particularly in respect of the forced removal of populations around oil fields and oil-related developments. The investigation was the result of allegations concerning the forced relocation of civilian populations in the vicinity of the oil field in the interest of a more secure environment for oil extraction by the Government of Sudan and its partners, which include Talisman Energy Inc., a Canadian oil company. In creating the Mission, the Department of Foreign Affairs declared that if it became evident that oil extraction is exacerbating the conflict in Sudan, or the the human rights violations, the Government of Canada may consider applying economic and trade sanctions. This report contains the results of the Mission's observations and meetings with members of the Government of Sudan, opposition leaders, human rights, civil society, and diplomatic representatives, as well as displaced Southern Sudanese and the UN officials trying to help them. The Mission also thoroughly examined Talisman Energy Inc.'s operations in Sudan and the extent to which oil extraction is exacerbating conflict in that country. The overall conclusion of the Mission's investigation is that while the on-going civil war in Sudan is not about oil, oil has become a key factor, and it is exacerbating the conflict. With regard to the role of Talisman, the conclusion was that the company did not do all that it could to keep itself fully informed as to what was happening, and while some progress has been made in curbing human rights violations, the oil operations in which Talisman is involved add to the conflict and suffering.

    Allergenicity Prosopis juliflora pollen antigen has been reported fromonly a few countries, including the US, South Africa, India and Kuwait. Insome parts of Saudi Arabia, species of Prosopis have been introduced by themillions as roadside ornamentation. There appear to be four flowering seasonsduring which pollen grains float in all directions. However, the role ofProsopis pollen as the sensitizing and/or rhinitis in the Kingdom has neverbeen evaluated. A total of 473 allergic patients suffering from the bronchialasthma in four different geographical regions (Abha, Qassim, Hofuf, Gizan),and attending allergy clinics and chest disease centers of university andMinistry of Health hospitals in the region were tested for immediatehypersensitivity reaction to Prosopis Juliflora allergens. Airborne pollengrains at one center were also studied for one full year, using volumetricsampling techniques. A total of 76.1% patients in Qassim, 37.5% in Gizan, 29%in Abha and 11% in Hofuf reacted positively to Prosopis antigen. Multiplesensitivities to other pollen antigens were detected in all patients. Thelevel of airborne Prosopis pollen detected in Gizan exceeded 90 grains m ofair. In view of documented evidence of Prosopis pollen as a sensitizingfactor in Saudi Arabia has been confirmed. However the cause of elicitationof symptoms in many multiple sensitive patients, together with the questionof cross-reactivities, needs thorough and detailed investigation. In vitroconfirmation of all positive results is also required to incriminate Prosopisas one of the major allergens in parts of Saudi Arabia. (author)

Additionally, to test the robustness of the results, the fully modified ordinary least squares (OLS regression, the dynamic OLS regression, and the Hansen test are used. Our results show that the variables are cointegrated when energy intensity is the dependent variable. It is also found that urbanization positively affects energy intensity in both the short term and the long term. Causality tests indicate that urbanization causes economic output that causes energy intensity in the long term. Our results do not support the urban compaction hypothesis where urban cities benefit from basic public services and economies of scale for public infrastructure. Therefore, measures that slow down the rapid urbanization process should be taken to reduce energy intensity in Saudi Arabia. In addition, reducing energy inefficiency in energy consumption should be a strategy to attain sustainable development in the near future in Saudi Arabia.

  17. A refined approach: Saudi Arabia moves beyond crude

    International Nuclear Information System (INIS)

    Saudi Arabia's role in global energy markets is changing. The kingdom is reshaping itself as a supplier of refined petroleum products while moving beyond its long-held role as a simple exporter of crude oil. This change is commensurate with the typical development trajectory of a state progressing to a more advanced stage of global economic integration. Gains from increased refining include reducing fuel imports and capturing margins now bequeathed to competitors. Refining also allows the kingdom to export its heavy crude oil to a wider array of customers, beyond select importers configured to handle heavy crudes. However, the move also presents strategic complications. The world's 'swing supplier' of oil may grow less willing or able to adjust supply to suit market demands. In the process, Saudi Arabia may have to update the old “oil for security” relationship that links it with Washington, augmenting it with a more diverse set of economic and investment ties with individual companies and countries, including China. -- Highlights: •Saudi Arabia is diverting crude oil into an expanding refining sector. •In doing so, the kingdom is moving beyond its role as global “swing supplier” of crude oil. •The kingdom will benefit from increased refining, including enhanced demand for heavy crude. •Strategic complications may force it to seek security partners beyond Washington

    This study assesses the potential impacts of climate change on water resources and the effect of statistical bias correction on the projected climate change signal in hydrological variables over the Upper Senegal Basin (West Africa). Original and bias corrected climate data from the regional climate model REMO were used as input for the Max Planck Institute for Meteorology-Hydrology Model (MPI-HM) to simulate river discharge, runoff, soil moisture and evapotranspiration. The results during the historical period (1971-2000) show that using the bias corrected input yields a better representation of the mean river flow regimes and the 10th and 90th percentiles of river flow at the outlet of the Upper Senegal Basin (USB). The Nash-Sutcliffe efficiency coefficient is 0.92 using the bias corrected input, which demonstrates the ability of the model in simulating river flow. The percent bias of 3.88% indicates a slight overestimation of the river flow by the model using the corrected input. The evaluation demonstrates the ability of the bias correction and its necessity for the simulation of historical river regimes. As for the potential changes of hydrological variables by the end of 21st century (2071-2100), a general decrease of river discharge, runoff, actual evapotranspiration, soil moisture is found under two Representative Concentration Pathways (RCP4.5 and RCP8.5) in all simulations. The decrease is higher under RCP8.5 with uncorrected data in the northern basin. However, there are some localized increases in some parts of the basin (e.g Guinean Highlands). The projected climate change signal of these above variables has the same spatial pattern and tendency for the uncorrected and bias corrected data although the magnitude of the corrected signal is somewhat lower than that uncorrected. Furthermore, the available water resources are projected to substantially decrease by more than -50% in the majority of the basin (especially in driest and hottest northern basin

    Full Text Available Abstract Background Although adult mosquito vectors of sylvatic arbovirus [yellow fever (YFV, dengue-2 (DENV-2 and chikungunya (CHIKV] have been studied for the past 40 years in southeastern Senegal, data are still lacking on the ecology of larval mosquitoes in this area. In this study, we investigated the larval habitats of mosquitoes and characterized their seasonal and spatial dynamics in arbovirus foci. Methods We searched for wet microhabitats, classified in 9 categories, in five land cover classes (agriculture, forest, savannah, barren and village from June, 2010 to January, 2011. Mosquito immatures were sampled monthly in up to 30 microhabitats of each category per land cover and bred until adult stage for determination. Results No wet microhabitats were found in the agricultural sites; in the remaining land covers immature stages of 35 mosquito species in 7 genera were sampled from 9 microhabitats (tree holes, fresh fruit husks, decaying fruit husks, puddles, bamboo holes, discarded containers, tires, rock holes and storage containers. The most abundant species was Aedes aegypti formosus, representing 30.2% of the collections, followed by 12 species, representing each more than 1% of the total, among them the arbovirus vectors Ae. vittatus (7.9%, Ae. luteocephalus (5.7%, Ae. taylori (5.0%, and Ae. furcifer (1.3%. Aedes aegypti, Cx. nebulosus, Cx. perfuscus, Cx. tritaeniorhynchus, Er. chrysogster and Ae. vittatus were the only common species collected from all land covers. Aedes furcifer and Ae. taylori were collected in fresh fruit husks and tree holes. Species richness and dominance varied significantly in land covers and microhabitats. Positive associations were found mainly between Ae. furcifer, Ae. taylori and Ae. luteocephalus. A high proportion of potential enzootic vectors that are not anthropophilic were found in the larval mosquito fauna. Conclusions In southeastern Senegal, Ae. furcifer and Ae. taylori larvae showed a more

The basic argument of these studies is that peace deals consolidate mainly the power of the signatories to the detriment of other major political forces. This article illustrates that, in contrast to many cases, the Comprehensive Peace Agreement (CPA, which was signed in 2005 between the government of Sudan represented by the ruling party, the National Congress Party (NCP and the Sudan People’s Liberation Movement/Army (SPLM/A, has led to an important political transformation in state structure as well as in power relations. Although the CPA enhanced the legitimacy of the SPLM and the NCP and consolidated their political domination, it, nevertheless, contributed to a significant political opening for other political forces in the North and in the South. The CPA put an end to the historically exclusive political hegemony of the North. This article focuses on the dynamics of relations between the SPLM and the NCP during the transitional period and illustrates how these dynamics have impacted upon the process of political transformation. Untersuchungen zu Friedensvereinbarungen kommen zumeist zu dem Schluss, dass die enthaltenen Machtteilungsklauseln einer langfristigen demokratischen Transformation abträglich sind. Als wichtigstes Argument wird dabei angeführt, dass Friedensvereinbarungen vor allem die Position der unterzeichnenden Partner stärken – zum Schaden anderer bedeutender politischer Kräfte. Der vorliegende Beitrag zeigt auf, dass – im Gegensatz zu vielen anderen Fällen – das Umfassende Friedensabkommen (Comprehensive Peace Agreement, CPA, das 2005 von der Regierung des Sudan, repräsentiert durch die Regierungspartei National Congress Party (NCP und die Sudan People’s Liberation Movement/Army (SPLM/A, unterzeichnet wurde, zu einem erheblichen Wandel sowohl

The aim of this study was to assess the level of public knowledge and attitude toward blood donation in Saudi Arabia. Methods: Using a previously validated questionnaire that comprises 38 questions to assess the levels of knowledge, attitudes, and motivations towards blood donation, 469 Saudi adults who attended different shopping malls in Riyadh, Saudi Arabia were surveyed. Multiple regression analyses were used to identify the significant predictors of blood donation, with the significance set at P<0.05. Results: Approximately half of all subjects (53.3% reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P<0.001. After adjustment for confounders, a higher knowledge score (t=2.59; P=0.01, a higher attitude score (t=3.26; P=0.001, and male sex (t=10.45; P<0.001 were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively, whereas a lack of time was the main reason for males (59.5%. Conclusion: Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor

  3. Survey of diseases and parasites of honeybees (Apis mellifera L.) in Sudan

    International Nuclear Information System (INIS)

    A survey of the honeybee diseases and parasites including questionnaires were carried out in eight bee areas in Sudan during the season 2002/03. About 117 local colonies and 324 packages of imported colonies of Apis mellifera were inspected, in addition to 25 colonies of Apis florea. All areas were found to be free of most bacterial brood diseases and fungal diseases, except the bacterial brood disease (Serratia marcescens) which was merely detected in 2.6% of Khartoum colonies. However, non infective dysentery was the only adult disease found during this study infecting 18.2% of Kordofan colonies. On the other hand, the parasitic mite (Varroa jacobsoni) was reported as first record in Sudan, detected only in Khartoum State infecting about 75% of colonies in apiaries and 27% of wild colonies. Sudanese honeybees were found to be characterized by hygienic behaviour of colonies which resist most pests and diseases, and no chemicals were used for control.(Author)

  4. Heavy Thunderstorm Synoptic Climatology and Forcing Mechanisms in Saudi Arabia.

    Meteorologists are required to provide accurate and comprehensive weather information for planning and operational aviation, agricultural, water projects and also for the public. In general, weather phenomena such as thunderstorms over the area between the tropics and the middle latitudes are not fully understood, particularly in the Middle East area, for many reasons such as: 1) the complexity of the nature of the climate due to the wide-ranging diversity in the topography and landscape in the area; 2) the lack of meteorological data in the area; and 3) the lack of studies on local weather situations. In arid regions such as Saudi Arabia, the spatial and temporal variation of thunderstorms and associated rainfall are essential in determining their effects on social and economic conditions. Thunderstorms form rapidly, due to the fact that the significant heating of the air from the surface and the ensuing rainfall usually occurs within a short period of time. Thus, understanding thunderstorms and rainfall distribution in time and space would be useful for hydrologists, meteorologists and for environmental studies. Research all over the world has shown, however, that consideration of local factors like Low Level Jets (LLJ), moisture flux, sea breezes, and the Red Sea Convergence Zone (RSCZ) would be valuable in thunderstorm prediction. The combined effects of enhanced low-level moisture convergence and layer destabilization due to upslope flow over mountainous terrain has been shown to be responsible for thunderstorm development in otherwise non-favourable conditions. However, there might be other synoptic features associated with heavy thunderstorms or cause them, but these features have not been investigated in any research in Saudi Arabia. Thus, relating the local weather and synoptic situations with those over the middle latitudes will provide a valuable background for the forecasters to issue the medium-range forecasts which are important for many projects

  10. Climate change, conflict and development in Sudan: global neo-Malthusian narratives and local power struggles.

    Dystopian accounts of climate change posit that it will lead to more conflict, causing state failure and mass population movements. Yet these narratives are both theoretically and empirically problematic: the conflict–environment hypothesis merges a global securitization agenda with local manipulations of Northern fears about the state of planetary ecology. Sudan has experienced how damaging this fusion of wishful thinking, power politics and top-down development can be. In the 1970s, global resource scarcity concerns were used locally to impose the fata morgana of Sudan as an Arab-African breadbasket: in the name of development, violent evictions of local communities contributed to Sudan's second civil war and associated famines. Today, Darfur has been labelled ‘the world's first climate change conflict’, masking the long-term political-economic dynamics and Sudanese agency underpinning the crisis. Simultaneously, the global food crisis is instrumentalized to launch a dam programme and agricultural revival that claim to be African answers to resource scarcity. The winners, however, are Sudan's globalized Islamist elites and foreign investors, whilst the livelihoods of local communities are undermined. Important links exist between climatic developments and security, but global Malthusian narratives about state failure and conflict are dangerously susceptible to manipulations by national elites; the practical outcomes decrease rather than increase human security. In the climate change era, the breakdown of institutions and associated violence is often not an unfortunate failure of the old system due to environmental shock, but a strategy of elites in wider processes of power and wealth accumulation and contestation.

    Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermonthica population. In the laboratory, 27 varieties were screened for post-attachment resistance using the rhizotron technique. Varieties displaying high post-attachment resistance, Umgar, NERICA5, and NERICA13 together with NERICA4, NERICA18, and Nipponbare, a lowland rice variety, were further evaluated for performance and Striga resistance in pot and semi-controlled open air experiments and for germination inducing activity in a laboratory. In addition, comparative studies on reaction of Umgar, Kosti1 and Kosti2, released varieties for commercial production in Sudan, to the parasite were performed in two pot experiments. In the pot experiments Umgar and NERICA5, consistently, sustained the lowest Striga emergence (harvest, was 2.0, 2.0, 4.8, 13.5, 13.3, and 18.3 on Umgar, NERICA5, NERICA13, NERICA4, NERICA18, and Nipponbare, respectively. Striga had no adverse effects on total above-ground parts and panicle dry weight in Umgar and NERICA5. Germination-inducing activity of root exudates, at 14 days after sowing onward, was markedly lower for Umgar than for NERICA5, NERICA13, NERICA4, and NERICA18. Based on these findings, Umgar has both pre and post-attachment resistance to a resident Striga population in Sudan. Kosti1 and Kosti2 did not exhibit Striga-resistance at the same level as Umgar. Further the resistance of NERICA5, a variety reported to be endowed with a broad spectrum resistance to Striga species and ecotypes, at least to one resident Striga population in Sudan was clearly indicated.

    Twenty-two commonly used pesticides were monitored during autumn, winter, and summer of 2004-2005 in 27 water samples from three sites along the White Nile in Sudan (former Sudan). Sites were selected to reflect pesticides gathered from drainage canals in central Sudan and from upstream sources. Collected samples were extracted and subjected to gas chromatographic analysis. Pesticides levels were measured in nanograms per liter. Pesticides residues were detected in 96 % of the samples with a total residue burden of 4132.6 ng L(-1), and an overall mean concentration and range of 50.99 and not detected-1570 ng L(-1), respectively. Ororganochlorines were the most frequently detected contaminants, which were found in 70 % of the samples, causing a total burden of 2852.8 ng L(-1), followed by pyrethroids 15 % of the samples, with a total burden of 926.5 ng L(-1). The tested herbicides were detected in ˂4 % of the samples with a total burden of 353.3 ng L(-1), while organophosphorus levels were below the detection limit. The most frequent contaminants were the following: heptachlor and its epoxide (52 % of samples), followed by DDTs (dichlorodiphenyltrichloroethanes) (DDT and DDE, in 19 % of the samples), cypermethrin and fenvalerate (in 11 % of the samples), and pendimethalin (in oxyfluorfen were not detected in the analyzed samples. Generally, levels were least in autumn, and followed by summer and winter. Sources of contamination might include agricultural lands in central Sudan and upstream sources. Both recent and old contaminations were indicated. PMID:27230426
