    Agriculture is the most important industry of the Sudan, and Gezira its major producing area. Gezira cotton earns most of the country's foreign exchange and the need to produce still more has led to intensification of production. The pressures created by this are accentuating old and creating new problems, thus putting strain on the technically good, but limited, resources of the Agricultural Research Corporation (ARC), which is responsible for most of the research on agricultural problems in the Sudan. The ARC therefore requested technical assistance from the IAEA to help with these studies. (author)

    The Sudan's population characteristics, geographical features, history, political conditions, and foreign relations are profiled. The 1984 population of Sudan has been estimated at 21.1 million, with an estimated annual growth rate of 3.0%. Approximately 25% of the Sudanese population resides in urban areas. Major religions are Islam, indigenous beliefs (in southern Sudan), and Christianity. The official language is Arabic, although English and tribal languages are also spoken. Education is compulsory for 9 years, but the attendance rate is only 48%. The infant mortality rate is 118.0/1000 live births, and life expectancy is 47 years. 78.4% of the work force is engaged in agriculture, 9.8% in industry and commerce, and 6% in government. The estimated gross national product for 1981-83 was $27.36 billion, with an estimated annual growth rate of 2.7% in 1982-83. Per capit income was approximately $361 in 1982, with an average annual inflation rate of 20-30%. Sudan's population is composed of 2 distinct cultures, Arab and black African, and effective collaboration between them poses one of the nation's principal internal problems. The 5 northern regions cover almost 2/3 of Sudan and include most urban centers. Most of the 13 million Sudanese who live in this area are Arabic-speaking Muslims of several distinct tribal groups. The southern region has a population of about 5.5 million and a predominantly rural, subsistence economy. The south also contains many tribal groups and uses many more languages than the north. Sudan's primary resources are agricultural. Although the country is trying to diversify its cash crops, cotton and cottonseed account for more than 50% of export earnings. Another large export crop is gum arabic. Grain sorghum is the principal food crop, and wheat is grown for domestic consumption. Livestock production has vast potential and many animals, particularly camels and sheep, are exported to other Arab countries. The inadequate transportation

    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: 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.

    2015-06-01

    Full Text Available The Sudan currency crisis in 2012 occurred when the Sudanese pound lost 66 percent of its value against the US dollar. In this article we adopt statistical methods such as the signal approach and econometric methods such as the Probit Model for identifying and evaluating the currency crisis. We utilize some economic indicators that have the ability to predict the crisis. We examined the capability of these indicators in generating an early warning system for Sudan currency crisis. The study confirms that the incidence of currency crisis in Sudan increases by increase in inflation rate, increase in import percentage of GDP, rise in claims against the central government, reduction in external reserves and existence of political crisis. Moreover, the study finds that the most important predictor of currency crisis in Sudan is decline in external reserves.

    Full Text Available Background: The Republic of the Sudan located in north-east of Africa and is considered to be a lower-middle income country. The country has well established healthcare system with many drawbacks mainly due to economic and managerial reasons followed by prolonged political instability and sanctions. Objective: The aim of this study is to give an insight over the health services system in Sudan and to analyze the strength, weakness, opportunities, and threats (SWOT. Materials and Methods: The search was done from two electronic databases: MEDLINE/Pubmed and from public search engines: Google Scholar and Google with key Search words used mainly as “Healthcare system in Sudan“. Additionally, SWOT analysis of healthcare system in Sudan was carried out based on the Roemer's model of health service system. Results: The Sudanese healthcare system was analyzed for different components of the system: The system in Sudan has full package of strategic plans and policies be it in a long term or short. Despite this there is poor implementation and organization along with frail health information system. The main external factors that drawback the system is the overall economic instability which resulted in cutting of the health expenditure. Conclusion: The Sudan is a rich country in terms of natural resources and population. Its health service system has strengths and weaknesses. It needs to build on its qualified human work force, stress on its well-designed short and long-term strategies on health care system and the partnership with external funding institutions, while overcoming the challenges on creating the proper health information system, economic support system and centralization of health service and professionals.

    2016-08-01

    Dental caries in preschool children remains a major dental public health problem and affects significant numbers of children in developed and developing countries. The incidence is increasing in developing countries, such as Sudan, because of lifestyle changes, absence of oral health-preventive services and inadequate access to oral health care. This study assessed the prevalence of dental caries and toothbrushing habits among 3- to 5-year-old preschool children in Khartoum State, Sudan, and described the correlation between the mean decayed, missing and filled tooth (dmft) score for primary teeth with toothbrushing and sugar consumption. The subjects were 553 preschool children with their mothers/guardians, selected by random sampling from the kindergartens of the seven localities of Khartoum State, Sudan. Data were obtained through clinical examination using a modified World Health Organization (WHO) examination data-capture sheet and through structured administered interviews with mothers/guardians. The prevalence of dental caries was 52.4%, with a mean dmft score of 2.3. There was an increase in the dmft scores with increasing age. The frequency of children who brushed their teeth regularly at least once a day was high (83.4%), lower dmft scores were associated with starting toothbrushing earlier in life and with increased frequency of brushing per day. Eating sugar-containing food was significantly associated with dmft score. The prevalence of dental caries was found to be high among 3- to 5-year-old preschool children, and caries experience increased with age. This was mostly associated with sugar consumption and therefore calls for educational interventions to control sugar intake. The toothbrushing habit is well established in Khartoum State, Sudan, as a large number of children were found to be brushing their teeth regularly. No significant association was found between feeding habits and dmft score. © 2016 FDI World Dental Federation.

The present study was planned to confirm the presence of piroplasmosis in camels from the Eastern region of the Sudan (Gedarif State using microscopical (blood film and molecular technique (PCR. A total of 55 camels of different sexes (34 females and 21 males were sampled from four localities of the state between January 2011 and January 2012. The prevalence rates using parasitological and molecular examinations were 43.6% and 74.5%, respectively. The prevalence rates significantly vary between the localities (p=0.011 but not between the different sexes (p=0.515. PCR technique showed higher sensitivity than microscopy. The present paper was to be the first report investigating camel piroplasmosis using both parasitological and molecular methods in the Eastern region of the Sudan. Further studies in the phylogenetic sequencing are to be continued for parasite speciation. Moreover, studies on the clinical and economic consequences of camel piroplasmosis are recommended.

    Full Text Available Sudan is one of the largest African countries, covering an area of 1.9 million km2—approximately one fifth of the geographic area of the United States. The population is 30 million people, the majority of whom (68% live in rural areas, as compared with the sub-Saharan African average of approximately 62%. Sudan is considered a lower-middle income country—with 47% of the population living below the poverty line and a gross domestic product (GDP of US $62 billion in 2010. In addition to excessive burden of communicable diseases such as malaria, tuberculosis, and schistosomiasis, Sudan is particularly susceptible to both natural and manmade disasters. Drought and flood are quite common due to Sudan’s proximity to and dependency on the Nile, and throughout history Sudan has also been plagued with internal conflicts and outbreaks of violence, which bring about a burden of traumatic disease and demand high quality emergency care. The purpose of this paper is to describe the state of emergency care and Emergency Medicine education, and their context within the Sudanese health care system. As is the case in most African countries, emergency care is delivered by junior staff: new graduates from medical schools and unsupervised medical officers who handle all types of case presentations. In 2001, increased mortality and morbidity among unsorted patients prompted the Ministry of Health to introduce a new triage-based emergency care system. In late 2005, twenty-one Emergency physicians delivered these new Emergency Services. In 2011, following a curriculum workshop in November 2010, the Emergency Medicine residency program was started in Khartoum. Currently there are 27 rotating registrars, the first class of whom is expected to graduate in 2015.

    Full Text Available Improving knowledge on local determinants of visceral leishmaniasis (VL is crucial to guide the development of relevant control strategies. This study aimed to identify individual and household level determinants of primary VL in 24 highly endemic villages of Tabarak Allah hospital's catchment area, Gedaref State, Sudan.From September 2012 to July 2013, in an unmatched case-control design, 198 patients with primary VL were compared to 801 controls free of VL symptoms and with a negative VL rapid test. Using random spatial sampling, controls were selected with a distribution of age, sex and village of residence proportionate to the distribution of the target population. Data were collected using a structured questionnaire.Children and men were at higher risk of VL. Reporting VL patient(s in the household in the previous year was the strongest VL risk factor. In a multivariate analysis, VL risk increased with household size, sleep location (outside the yard, not in the farm, evening outdoor activities in the rainy season (playing, watching TV, radio listening, use of ground nut oil as animal repellent and of smoke of Acacia seyal as indoor repellent, presence of dogs in the yard at night, Acacia nilotica in the yard's immediate surroundings and of a forest at eye range. VL risk appeared to decrease with the use of drinking water sources other than the village water tank, a buffer distance from the adjacent house yard, and with the presence of animals other than dogs in the yard at night. In contrast with previous studies, housing factors, mosquito-net use, black cotton soil, ethnicity, socioeconomic index, presence of Balanites aegyptica and Azadirachta indica in the yard were not independent VL determinants.Although these results do not provide evidence of causality, they provide useful suggestions for guiding further intervention studies on VL preventive measures.

    Full Text Available Abstract Background Phlebotomus papatasi the vector of cutaneous leishmaniasis (CL is the most widely spread sand fly in Sudan. No data has previously been collected on insecticide susceptibility and/or resistance of this vector, and a first study to establish a baseline data is reported here. Methods Sand flies were collected from Surogia village, (Khartoum State, Rahad Game Reserve (eastern Sudan and White Nile area (Central Sudan using light traps. Sand flies were reared in the Tropical Medicine Research Institute laboratory. The insecticide susceptibility status of first progeny (F1 of P. papatasi of each population was tested using WHO insecticide kits. Also, P. papatasi specimens from Surogia village and Rahad Game Reserve were assayed for activities of enzyme systems involved in insecticide resistance (acetylcholinesterase (AChE, non-specific carboxylesterases (EST, glutathione-S-transferases (GSTs and cytochrome p450 monooxygenases (Cyt p450. Results Populations of P. papatasi from White Nile and Rahad Game Reserve were sensitive to dichlorodiphenyltrichloroethane (DDT, permethrin, malathion, and propoxur. However, the P. papatasi population from Surogia village was sensitive to DDT and permethrin but highly resistant to malathion and propoxur. Furthermore, P. papatasi of Surogia village had significantly higher insecticide detoxification enzyme activity than of those of Rahad Game Reserve. The sand fly population in Surogia displayed high AChE activity and only three specimens had elevated levels for EST and GST. Conclusions The study provided evidence for malathion and propoxur resistance in the sand fly population of Surogia village, which probably resulted from anti-malarial control activities carried out in the area during the past 50 years.

Vegetation cover, plant density, carrying capacity, and biomass production were assessed. Chemical analyses were done for selected plants to determine their nutritive values. The results showed high significant differences in vegetation attributes (density, cover and biomass production between closed and open areas. Closed areas had higher carrying capacity compared to open rangelands. Crude protein (CP and ash contents of range vegetation were found to decrease while Crude fiber (CF and Dry matter yield (DM had increased with growth. The study concluded that closed rangelands are better than open rangelands because it fenced and protected. Erosion index and vegetation degradation rate were very high. Future research work is needed to assess rangelands characteristics and habitat condition across different ecological zones in North Darfur State, Sudan.DOI: http://dx.doi.org/10.3126/ije.v3i3.11093 International Journal of Environment Vol.3(3 2014: 332-343

    Full Text Available Introduction Bleeding due to oesophageal varices is the most common cause of upper gastrointestinal tract haemorrhage in Gezira State, Central Sudan. Endoscopic injection sclerotherapy (EST is a valuable therapeutic modality for the management of variceal bleeding. Other options for treatment such as variceal band ligation are either expensive or unavailable. Objectives A retrospective study to evaluate the outcome of (EST in the management of bleeding oesophageal varices due to portal hypertension in Gezira State, the centre of a developing country, Sudan. Methods A total of 1073 patients, during 2001-2010, were carefully selected particularly those with bleeding oesophageal varices consequent to portal hypertension. EST was performed using a standard technique and ethanolamine oleate (5% was utilized as sclerosing agent. Results There were 777 males (72.4% and 296 females (27.6% in a ratio of 2.6. The causes of portal hypertension were found to be schistosomal periportal fibrosis (PPF in 1001 (93.3% patients, liver cirrhosis in 60 (5.5% mixed PPF and cirrhosis in seven (0.7% and portal vein thrombosis in five (0.5% patients. Full obliteration of varices required a mean of four sessions with a range of 2-6. In the present study 350 (32.6% patients have been followed up until complete sclerosis of varices. Conclusion This study provides evidence that endoscopic injection sclerotherapy is an important component in the management of bleeding oesophageal varices caused by hypertension. It is a safe and effective procedure.

  12. Re-engineering the state, awakening the nation: Dams, islamist modernity and nationalist politics in Sudan

    Full Text Available This article investigates how and why dam building has fulfilled a crucial role in hegemonic projects of elite consolidation and nation-building. By drawing on the case of Sudan’s Dam Programme and the associated propaganda the Khartoum government has produced, we show how the dams have not just served to materially restructure the Sudanese political economy but have also been essential in the attempted rekindling of the identity of both the regime and the country. Massive investment in hydro-infrastructure dovetailed with the political rebalancing of an authoritarian system in crisis, turning dam-builders into nation-builders: the message of the dams as midwife to a pious, prosperous and revitalised Sudan allowed it to reconcile the nationalism of its military and security wing with the enduring ambitions for transformation of its Islamist base. Dam building in Sudan, as elsewhere, has thus meant a physical redrawing of the landscape and intensified rent creation and seeking but also embodies a high modernist narrative that matches the interests and worldviews of very different constituencies. This, we argue, helps explain its salience in earlier periods of state-building and nation-building, as well as contemporarily

    Full Text Available Abstract Background In this paper, we report an outbreak of bovine trypanosomiasis in Kurmuk District, Blue Nile State, Sudan that involved an infection with four Trypanosoma species in cattle. The outbreak occurred in June 2010 when indigenous cattle, mainly Kenana and Fulani breed types, crossed the national Sudanese border to Ethiopia and returned. A veterinarian was notified of massive deaths in the cattle populations that recently came from Ethiopia. All animals involved in the outbreak were from the nomadic Fulani group and resident local cattle were not infected and no death has been reported among them. A total of 210 blood samples were collected from the ear vein of cattle. A few samples were also collected from other domestic animals species. Parasitological examinations including hematocrit centrifugation techniques (HCT and Giemsa-stained thin blood films were carried out. ITS1-PCR, which provides a multi-species-specific diagnosis in a single PCR, was performed. Findings Parasitological examinations revealed that 43% (91/210 of the affected cattle population was infected with two morphologically distinct trypanosomes. Seventy animals (33.3% were infected with T. vivax and twenty one (10% with T. congolense. In contrast, ITS1-PCR was able to identify four Trypanosoma species namely T. vivax, T. congolense, T. simiae and T. brucei in 56.7% (80/141. T. brucei showed the highest prevalence of 36.9% (52/141 and the lowest 19% (27/141 was displayed by T. congolense. Furthermore, and because ITS1-PCR could not differentiate between T. brucei subspecies, serum resistance-associated (SRA gene based PCR was used to detect the human T. brucei rhodesiense in T. brucei positive samples. None of the samples was shown positive for T. b. rhodesiense. The identity of the 400 bp PCR product originating from T. simiae, was further confirmed by sequencing and subsequent phylogenetic analysis. Conclusions The outbreak of bovine trypanosomiasis occurred

    Draught animal technology (DAT) can potentially play a central role in agriculture transformation for traditional farmers. This study surveyed the state of DAT in En-Nhoud area, North Kordofan State, Sudan in an attempt to have a clear view of the changes brought about by introducing the technology. The study followed the cross-sectional survey design. Farmers were selected from ten clusters (villages) and data were collected using questionnaires and face to face interviews with farmers in addition to group discussions with them and the different actors in the field. The results showed that farmers appreciate the role played by DAT, but they highlighted the need for further capacity building and technical backup. Harnessing issues are not well understood and applied by the farmers. The different actors involved in DAT in the area lack networking and coordination, and this reflected on the many problems and constraints faced by the farmers.

    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.

    Safety performance evaluation enables decision makers improve safety acts. In Sudan, accident records, statistics, and safety performance were not evaluated before maintenance of accident records became mandatory in 2005. This study aimed at evaluating and comparing safety performance by accident records among different cities and industrial sectors in Khartoum state, Sudan, during the period from 2005 to 2007. This was a retrospective study, the sample in which represented all industrial enterprises in Khartoum state employing 50 workers or more. All industrial accident records of the Ministry of Manpower and Health and those of different enterprises during the period from 2005 to 2007 were reviewed. The safety performance indicators used within this study were the frequency-severity index (FSI) and fatal and disabling accident frequency rates (DAFR). In Khartoum city, the FSI [0.10 (0.17)] was lower than that in Bahari [0.11 (0.21)] and Omdurman [0.84 (0.34)]. It was the maximum in the chemical sector [0.33 (0.64)] and minimum in the metallurgic sector [0.09 (0.19)]. The highest DAFR was observed in Omdurman [5.6 (3.5)] and in the chemical sector [2.5 (4.0)]. The fatal accident frequency rate in the mechanical and electrical engineering industry was the highest [0.0 (0.69)]. Male workers who were older, divorced, and had lower levels of education had the lowest safety performance indicators. The safety performance of the industrial enterprises in Khartoum city was the best. The safety performance in the chemical sector was the worst with regard to FSI and DAFR. The age, sex, and educational level of injured workers greatly affect safety performance.

    Spotted fever group (SFG) rickettsiosis is caused by obligatory intracellular Gram-negative bacteria that belong to the genus Rickettsia . Ticks belonging to the family Ixodidae can act as vectors, reservoirs or amplifiers of SFG rickettsiae. This study was conducted to estimate the seroprevalence of SFG rickettsioses in cattle, sheep and goats from Khartoum State, Sudan. Blood samples were collected from a total of 600 animals (sheep, goats and cattle) from 32 different farms distributed in three locations in Khartoum State during the period January to December 2012. Sera were tested for antibodies against SFG rickettsiae using IFAT. The prevalence of seropositivity was 59.3% in sheep, 60.1% in goats and 64.4% in cattle. Season was significantly ( P <  0.05) associated with seroprevalence of SFG rickettsiae in cattle during winter. The SFG rickettsiae antibodies prevalence was significantly higher in female compared with male in sheep, but there were no significant differences between male and female in either cattle or goats. The prevalence was significantly higher in adult animals compared with young in both sheep and goats. With regard to management system, there was a significant difference in the prevalence in cattle raised in closed system compared with those raised in semi-intensive system. In contrast, there was significant difference in the seroprevalence of SFG in sheep where the prevalence was higher in the sheep raised in semi-intensive system compared with those raised in close system. There was no significant difference in the seroprevalence in goats with regard to management systems. The unexpected high prevalence of SFG rickettsia antibodies in domestic ruminants sera suggest that the veterinary and public health impact of these agents in Sudan need further evaluation especially in humans.

    Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease caused by CCHF virus (CCHFV) of the genus Nairovirus in the family Bunyaviridae. CCHFV causes subclinical infection in domestic livestock and an often fatal hemorrhagic illness in humans, with approximately 30% mortality rates. In the present study, a cross-sectional serosurvey was conducted in a total of 282 randomly selected cattle from five localities in East Darfur State, Sudan. The exposure status to CCHF was determined using enzyme-linked immunosorbent assay (ELISA) for detection of CCHFV-specific IgG antibodies in cattle serum samples. The CCHFV-specific IgG antibodies were detected in 54 out of 282 animals, accounting for a 19.14% prevalence rate. Older cattle (>2 years of age) were approximately five times more likely to be infected with the virus (OR=4.90, CI=1.28-18.98, p-value=0.02). Heavily tick-infested cattle (ticks all over the body) were at 11 times higher at risk compared to tick-free animals (OR=11.11, CI=2.86-43.25, p-value=0.01). Grazing system is another factor affecting CCHF, where cattle grazing on open system were 27 times more at risk compared to other grazing systems (OR=27.22, CI=7.46-99.24, p-value=0.001). There was an association between localities and CCHF cattle (OR=0.24, CI=0.07-0.83, p-value=0.02). This study confirms the exposure of cattle to CCHF in East Darfur and identifies potential risk factors associated with the disease. Further epidemiological studies and improved surveillance are urgently needed to prevent a possible outbreak of CCHF among humans in the Darfur region of Sudan. Copyright © 2015 Elsevier GmbH.

    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.

    The willingness-to-pay (WTP) with contingent valuation (CV) method has been proven to be a valid tool for the valuation of non-market goods or socio-economic costs of road traffic accidents among communities in developed and developing countries. Research on accident costing tends to estimate the value of statistical life (VOSL) for all road users by providing a principle for the evaluation of road safety interventions in cost-benefit analysis. As in many other developing countries, the economic loss of traffic accidents in Sudan is noticeable; however, analytical research to estimate the magnitude and impact of that loss is lacking. Reports have shown that pedestrians account for more than 40% of the total number of fatalities. In this study, the WTP-CV approach was used to determine the amount of money that pedestrians in Sudan are willing to pay to reduce the risk of their own death. The impact of the socioeconomic factors, risk levels, and walking behaviors of pedestrians on their WTP for fatality risk reduction was also evaluated. Data were collected from two cities-Khartoum and Nyala-using a survey questionnaire that included 1400 respondents. The WTP-CV Payment Card Questionnaire was designed to ensure that Sudan pedestrians can easily determine the amount of money that would be required to reduce the fatality risk from a pedestrian-related accident. The analysis results show that the estimated VOSL for Sudanese pedestrians ranges from US$0.019 to US$0.101 million. In addition, the willingness-to-pay by Sudanese pedestrians to reduce their fatality risk tends to increase with age, household income, educational level, safety perception, and average time spent on social activities with family and community.

    Bluetongue virus (BTV) is an insect-transmitted virus, which causes bluetongue disease (BT) in sheep and a fatal hemorrhagic infection in North American white-tailed deer. However, in cattle the disease is typically asymptomatic and no overt clinical signs of disease appear to be associated with BTV infection. Serological evidence and isolation of different BTV serotypes have been reported in Sudan, however, no information is currently available in regard to previous exposure of Sudanese livestock to BTV infection in East Darfur State, Sudan. To determine the prevalence of BTV antibodies and to identify the potential risk factors associated with BTV infection among cattle in East Darfur State, Sudan. A total of 224 blood samples were collected randomly from five localities in East Darfur State, Sudan. The serum samples were screened for detection of BTV-specific immunoglobulin G (IgG) antibodies using a competitive enzyme-linked immunosorbent assay (c-ELISA). Serological evidence of BTV infection was observed in 150 out of 224 animals accounting for a 67% prevalence rate among cattle in East Darfur State. Older cattle (>2 years of age) were six times more likely to be infected with BTV (OR = 6.62, CI = 2.87-15.26, p-value = 0.01). Regarding animal source (contact with other herds) as a risk factor, it was shown that cattle purchased from market or introduced from other herds were 3 times at higher risk of being infected with BTV (OR = 3.87, CI = 1.07-13.87, p value = 0.03). Exposure of cattle to the insect vector increased the risk of contracting BTV infection by six times compared to non-exposed cattle (OR = 6.44, CI = 1.53-27.08, p value = 0.01). The present study indicated that age, animal source and the intensity of the insect vector are influential risk factors for BTV infection in cattle in the Darfur region. Surveillance for BTV infection should be extended to include other susceptible ruminants and to study the distribution of the insect vectors to better

    Full Text Available The aim of this study was to determine the occurrence of tuberculosis in cattle slaughtered at Nyala abattoirs, South Darfur State, Sudan during the period April 2006 – May 2008. In total 2794 cattle were examined for tuberculous lesions. Tuberculous lesions (n = 163 were found in 40 (1.4% animals, among which seven had generalized tuberculosis and 33 localized tuberculosis, mainly in the lungs, thoracic lymph nodes, and/or in the liver, spleen, kidneys and mesenteric lymph nodes. Tissue samples were collected either in 10% formal saline for routine histopathology or in ice packs for direct microscopy and culturing. Direct microscopy showed that 124 (76.1% tuberculous lesions harbored acid fast bacilli, whereas 17 (10.4% isolates of Mycobacterium spp. were recovered in pure Lowenstein-Jensen medium cultures and identified as M. bovis (n = 11 and M. farcinogenes (n = 6. Granulomatous inflammation was evident in all sections of tuberculous lesions. Further studies are needed to identify mycobacteria species causing tuberculosis in other animal species.

    Full Text Available Abstract The study was conducted over a two years period of 2012 and 2013 at three sites of Alfashir locality Ummarahik 25km north of Alfashir Fashar in eastern part of Alfashir about 5km and Berka 30km west of Alfashir Western Sudan in semi-arid zone. The aim of this study was to assess rangeland attributes. Measurements of plant density vegetation cover range production and carrying capacity were assessed. Results showed that total forage production was low and inadequate to satisfy requirements of livestock for inhabiting the area average range production all over the area was found to be 50.68 kgha and 59.21 kgha for the seasons 2012 and 2013 respectively. The average ground cover was about 34.71 and 42.41 for two seasons. The average plant density for the first season was 27.1 plantm2 while the average plant density for the second season was 29.4 plantm2. The study concluded that unwise utilization and exploitation of the rangelands particularly by man causes range deterioration and serious reduction in range production in both quantity and quality so the study suggested that improvement and rehabilitation such lands rangelands should be done. Further research work is needed to assess rangeland attributes across different ecological zones in North Darfur State.

    Linear programming was used to simulate the farming systems of small pump schemes in Shendi Area, River Nile State, Sudan, to assess the prospect for technology use in cool-season food legumes and wheat. Different production activities, with respect to target crops, were identified to reflect different technology levels. The model constraints were the pump capacity, the scheme size and family labour. Alternative versions of the model were developed to examine possible production options that exist and to examine the effects of alternative resource levels and policy options, which are likely to affects adoption. The model results revealed that while farmers traditional practices were not economically feasible options, tendency is for adoption of medium rather than the recommended high technology levels. This reflects actual farmers behaviour, particularly for irrigation water, and indicates that water is the main resource constraint. The results also showed that the technology is not well supported by the traditional institutions of production relation, which create conflicting perception between resource owner to wards technology use.(Author)

    To evaluate the ultrasound findings of urinary schistosomiasis in Quran school (Khalwas) children in Gezira State Sudan, we studied all the students from two schools. A total of 103 boys were tested for urinary schistosomiasis using the urine filtration method. Schistosoma haematobium (S. haematobium) eggs were counted. Ultrasound was performed for all the positive subjects. Seventy-three (71%) subjects were positive for S. haematobium. The mean age was 11.3 ± 2.9 years. Sixty-six (90.4%) subjects showed urinary tract abnormalities. The findings revealed the following degrees of wall thickening: 53.0% mild, 18.2% moderate and 21.2% severe. Urinary bladder polyp(s) were noted in 43.3% (single) and 40.9% (multiple) of the subjects, and calcification of the bladder wall was observed in 7.6% subjects. Ureteric dilatation was noted in 38/73 (52.0%), while hydronephrosis was detected in 19/73 (26.3%). The vast majority of urinary tract schistomiasis lesions were in the urinary bladder. Ultrasound is a useful tool for identifying the morbidity of S. haematobium in endemic areas.

    Eastern Sudan has high prevalence of female circumcision and child marriage constituting a risk for developing obstetric fistula. Few studies have examined gender roles' relation with obstetric fistula in Sudan. To explore the associated power-relations that may put women at increased risk for developing obstetric fistula, we conducted nine interviews with women living with obstetric fistula in Kassala in eastern Sudan. Using a Foucauldian discourse analysis, we identified three discourses: powerlessness, normalization, and covert resistance. Existing power-relations between the women and other societal members revealed their internalization of social norms as absolute truth, and influenced their status and decision-making power in regard to circumcision, early marriage, and other transformative decisions as well as women's general behaviors. The women showed subtle resistance to these norms and the harassment they encountered because of their fistula. These findings suggest that a more in-depth contextual assessment could benefit future maternal health interventions.

    Data on childhood epilepsy in Sudan are scarce and the only published study on its prevalence was published in 1983. This study aimed to determine the current prevalence of epilepsy in school children in Khartoum State. This is an analytical population-based, cross-sectional study conducted in Khartoum State, Sudan. The study included students in the basic (primary) schools aged 6-14 years. Simple random sampling was used to draw a cluster of four of the seven localities comprising Khartoum State. The sample frame consisted of 1609 public schools (808,624 pupils) and 787 private schools (194,613 pupils), a total of 2396 schools (1,003,237 pupils). A sample size of 75 940 pupils was estimated and 250 schools were drawn from a sample frame of 2396 schools using a stratified random sampling technique. Consent was obtained from the headmaster/head teacher of the selected schools who arranged a meeting with the tutor/teacher responsible for each class. The study team asked whether any of the pupils was ever noticed or known to have had any kind of seizures, and a confidential letter was sent to the parents of each identified pupil. The letter included an explanation of the aims of the study, information on the research group and the kind of help the research group could offer; contact numbers and email addresses were made available if they wished to participate in this study. Those who consented to participate were then given an appointment at the Epilepsy Outpatient Department, Gaafar Ibnauf Children's Hospital, Khartoum where they were evaluated by the paediatric neurologist. Altogether, 74,949 pupils were enrolled for the study, 398 of whom were identified initially as having seizures and 332 of whom (83.4%) were identified by a paediatric neurologist. Of the 332, 303 (91.3%) proved to have epileptic seizures, 250 (82.5%) were known to have epilepsy, and 53 (17.5%) were newly diagnosed during the survey. The male to female ratio was 1.5:1.

    Full Text Available Background Visceral leishmaniasis (VL (known as kala azar is associated with low socioeconomic status, and patients are among the poorest. In Sudan visceral leishmaniasis is one of the most important infectious diseases with an estimated 20,000 cases annually; 80% in Gedaref State. The social, economic, and behavioral factors play an important role in establishing both individual and population-wide vulnerability to the disease. Methods A descriptive cross-sectional community based study was conducted at Barbar Elfugara village to determine the socioeconomic and behavioral risk factors among head of the households regarding infection with VL. A sample size of 224 heads of households was determined using statistical formula. Data were collected using questionnaire, observation check list and reviewing records. SPSS was used for analyzing data and chi-square test for the association between different variables. Results The main risk factors of kala azar were gender {males were affected more than twice females (24.4%:9.1%}; the age group {<20 yrs (42.9%}. Other factors were illiteracy (30.1%, occupation mainly farmers (28.2%, poverty (39.1%, large families (31% and living in one house room (45.5%. The results showed that the respondents were highly aware of kala azar (97.3%, the majority (90.8% believed that kala azar is transmitted by an insect but only (55.5% of them were aware of the sand fly. The respondents showed poor knowledge of breeding sites (25.5% and biting time (34.5%. Consistent use of insecticide treated nets and sleeping inside habit were strongly protective (P=0.01 (P=0.00. Conclusion The study showed that the low socioeconomic status and poor knowledge of KA transmission are the major risk factors for KA infection in the area.

    Full Text Available The severe Sahel catastrophe in 1968–1974 as well as repeated famines and food shortage that have hit many African countries during the 1970s have highlighted the need for further research concerning land degradation and environmental monitoring in arid and semi-arid areas. Land degradation, and desertification processes in arid and semi-arid environment were increased in the last four decades, especially in the developing countries like Sudan. To test to what extent remote sensing and geographical information science (GIS methodologies and techniques could be used for monitoring changes in arid and semi-arid regions and environment, these methodologies have long been suggested as a time and cost-efficient method. In this frame, spectral Mixture Analysis (SMA, Object-based oriented classification (Segmentation, and Change Vector Analysis are recently much recommended as a most suitable method for monitoring and mapping land cover changes in arid and semi-arid environment. Therefor the aim of this study is to use these methods and techniques for environmental monitoring with emphasis on desertification and to find model that can describe and map the status and rate of desertification processes and land cover changes in semi-arid areas in White Nile State (Sudan by using multi-temporal imagery of the Landsat satellite TM (1987, TM (2000, and ETM+ (2014 respectively. The paper also discusses and evaluates the efficiency of the adapted methodologies in monitoring the land degradation processes and changes in the arid and semi-arid regions.

    To complete the baseline trachoma map of Sudan by estimating the prevalence of trachoma and associated risk factors in the five Darfur States and Khartoum State. Using a standardized methodology developed for the Global Trachoma Mapping Project, we undertook a cross sectional, community-based survey in each of 32 evaluation units (EUs) covering all accessible districts. We enumerated a total of 84,568 individuals, with 73,489 people (86.9%) examined from 20,242 households in 908 villages. The highest prevalence of trachomatous inflammation - follicular (TF) in children was found in El Fashir district (18.7%), and the lowest in El Malha district (0.0%). Five districts (El Fashir, Zalinji, Azoom, Maleet, and El Koma) were in the three EUs that had TF prevalences above the 10% threshold at which the World Health Organization recommends mass treatment with azithromycin, together with facial clean3liness and environmental improvement interventions, for at least 3 years. The highest trachomatous trichiasis prevalence in adults was found in the EU composed of Forbranga and Habillah (1.2%), and the lowest in the EU composed of As-salam and Belale districts in South Darfur (0.0%). TF in children was independently associated with younger age, unimproved sanitation in the household, having ≥5 children in the household, outside annual maximum temperatures Darfur, but in general the prevalence throughout Darfur and Khartoum was low.

    This study deals with the theoretical and experimental aspects of X-ray diffraction (XRD) technique. Moreover the XRD technique has been used to investigate the clay mineral types and their distribution for samples obtained from exploration wells in the Mugald Sedimentary Basin in Western Sudan. The studied samples range in depth from 1524 m to 4572 m. The XRD analysis of samples shows that they consist of kaolinite, smectite, illite, chlorite and the mixed-layer smectite/illite. Kaolinite has higher abundance (15 - 72 %) followed by illite (7 - 34 %), smectite (11 - 76 %) and the less abundance of chlorite and the mixed-layer smectite/illite. Non-clay minerals found include quartz and cristabolite. The clay mineral types and their vertical distribution reflect various controls such as environmental, burial diagenesis, source rocks and climatic influences in the Muglad Sedimentary Basin.

Even though the Sphere Handbook was chosen as the best available "gold standard" to benchmark Nafeer's efforts, it showed significant limitations in effectively measuring this group. It appears that independent spontaneous volunteer initiatives, like Nafeer, potentially can improve community resilience and play a significant role in the humanitarian response. Such organizations should be the subject of increased research activity. Relevant bodies should consider issuing separate guidelines supporting spontaneous volunteer organizations.

    Fresh vegetables are considered as vital nutrients of a healthy diet as they supply the body with essential supplements. The consumption of raw vegetables is the main way for transmission of intestinal parasitic organisms. This study was aimed at detecting the parasitic contamination in fresh vegetables sold in two central open-aired markets in Khartoum state, Sudan. In this prospective cross-sectional study, a total of 260 fresh vegetable samples and 50 water samples used to sprinkle vegetable(s) were collected from two central open-aired markets (namely; Elshaabi and Central markets) during November 2011 to May 2012. The samples were microscopically examined for detection of parasitic life forms using standardized parasitological techniques for protozoans and helminthes worms. Of the 260 fresh vegetable samples, 35 (13.5 %) were microscopically positive for intestinal parasites whereas 7/50 (14 %) of water samples used to sprinkle vegetable(s) were found positives. Remarkably, high level of contamination in fresh vegetable samples was recorded in lettuce (Lactuca sativa) 36.4 % (4/11) while cayenne pepper (Capsicum annuum) and cucumber (Cucumis sativus) were not contaminated. The identified protozoans and helminthes were Entamoeba histolytica/dispar, Entamoeba coli, Giardia lamblia, Ascaris lumbricoides, Strongyloides stercoralis, T. trichiura and hookworms. The most predominant parasite encountered was E. histolytica/dispar (42.9 %) whereas both T. trichiura and A. lumbricoides (2.9 %) were the least detected parasites. None of the fresh vegetables had single parasitic contamination. The highest percentages found in water samples used to sprinkle vegetable(s) was for Strongyloides larvae 60 % (3/5). It is worth-mentioned that the rate of contamination in Elshaabi market was higher compared with Central market. However, there was no significant correlation between the type of vegetables and existence of parasites in both markets and a high significant

    Natural radioactivity is a source of continuous exposure to human beings. In Port Sudan city, the main port of Sudan, data on the levels of natural radioactivity in soil is required. The aim of this study was to measure the activity concentration as well as the absorbed dose and annual effective dose of the naturally occurring radionuclides 238 U, 232 Th, and 40 K in soil samples collected from different locations around Red Sea costa areas in Port Sudan city. Activity concentrations were measured using gamma ray spectrometry (Nal) detector. Results showed that the average activity concentration of 238 U, 232 Th and 40 K were found to be 21.86, 17.55, 85.50 Bqkg 1 , respectively, with an average absorbed dose of 10.42, 9.40 and 3.57 nGyh 1 , respectively. The average annual effective dose values were found to be 11.89, 11.54 and 4.37 μSvy 1 for 238 U, 232 Th and 40 K, respectively. The measured values were comparable with other global radioactivity measurements and found to be safe for public and environment.(Author)

  2. A questionnaire survey of poultry layer farmers in Khartoum State, Sudan, to study their antimicrobial awareness and usage patterns

    Full Text Available An initial census of layer farms in Khartoum State, Sudan, was carried out in late 2007 and early 2008 and found that there were 252 layer farms with a total population of 2 221 800 birds. This paper reports the findings of the census. Based on this information, a structured questionnaire survey of 92 farms was then conducted in the state in April 2008 to collect data on antibiotic usage, demographic data and public health awareness. Ninety-eight per cent of participating farms comprised open-sided houses. It was found that 49% of the farms surveyed were on antibiotic treatment when the survey was conducted, whilst 59% of the farms had used antibiotics within the last 3 months. The study found that farmers and producers had a lack of knowledge about antimicrobial residues, their withdrawal periods and the risk posed by the consumption of these residues. The study also concluded that traditional farming systems in Sudan relied heavily on antimicrobial medication to control disease and almost half of the farms surveyed were treating their flocks with antimicrobials. In addition to this, there was a lack of disease control programmes which probably resulted in a massive use of antibiotics to control endemic diseases. This was further compounded by the absence of governmental supervision and control on the use of drugs.

    Both inadequate and high intakes of iodine are associated with thyroid disease and associated abnormalities. Consumption of foods deficient in iodine induces hypothyroidism. Conversely, excessive intake of the nutrient precipitates hyperthyroidism. Iodine deficiency causes impairment of thyroid hormonogenesis resulting in goiter (struma), cretinism which is associated with increased prenatal and infant mortality, deafness, motor disabilities and mental retardation due to damage during fetal and neonatal brain development. We have assessed the iodine status of school children from the locality of Port Sudan, Red Sea State of Eastern Sudan. The primary sources of iodine of the children are mainly iodized salt and rations supplied by local donors and various aid agencies operating in the Sudan. Male and female children (n=141), aged 6 to 12 years (median age 9.8 years), were selected for the survey using a multistage random sampling technique, between May 22 and August 25, 2006. All the children were assessed for urinary iodine and visible goiter. In addition, the iodine content of twenty salt samples was determined using the lodometric titration method and spot test kits. The components of other foods that are routinely consumed by the children and households were noted using a questionnaire form. Urinary iodine concentration exceeded 300 microg/l and 1000 microg/l in 65% and 9.9% of the children, respectively. The highest urinary iodine level was 1470 microg/l. The prevalence of visible goiter was 17%. All the salt samples collected from the schools had more than 150mg potassium iodate per kg of salt. The results of this pilot survey reveal that excessive intake of iodine in children exists in Port Sudan. Inappropriate and unregulated local fortification of salt and lack of monitoring of the imported and donated salt is the primary reason for the excessive intake. There is an urgent need for a regulatory mechanism during the process of iodine fortification and at

    Little is known about the coverage of routine immunization service in South Darfur state, Sudan. Therefore, this study was conducted to determine the vaccination rate and barriers for vaccination. A cross-sectional community-based study was undertaken in Nyala locality, south Darfur, Sudan, including urban, rural and Internal Displaced Peoples (IDPs) population in proportional representation. Survey data were collected by a questionnaire which was applied face to face to parents of 213 children 12-23 months. The collected data was then analyzed with SPSS software package. Results showed that vaccination coverage as revealed by showed vaccination card alone was 63.4% while it was increased to 82.2% when both history and cards were used. Some (5.6%) of children were completely non-vaccinated. The factors contributing to the low vaccination coverage were found to be knowledge problems of mothers (51%), access problems (15%) and attitude problems (34%). Children whose mother attended antenatal care and those from urban areas were more likely to complete their immunization schedule. In conclusion, the vaccination coverage in the studied area was low compared to the national coverage. Efforts to increase vaccination converge and completion of the scheduled plan should focus on addressing concerns of caregivers particularly side effects and strengthening the Expanded Programmer on Immunization services in rural areas.

    Recent research suggests an emergence of eating disorders [ED] in non-western settings for unknown reasons. This research investigates the presence of ED in Khartoum State [Sudan], and explores relevant factors amongst women at risk of ED and stakeholders involved with mental health care and policy-making. Women from four summer schools were approached and screened for risk of ED using a validated and adapted form of the Eating Attitudes Test-26. Focus groups were performed within the schools, selected participants at high risk were interviewed, and interviews with stakeholders were performed. Around a third (32.6%) of participants scored as having high risk of ED. Interviews showed recurring themes determining eating attitudes including: intention, knowledge, environment and habit. Stakeholders' opinions depended on whether they work directly with those affected by ED or in policy-making. The former advocated increased attention on ED, the latter did not. Overall, services for ED were lacking. A high presence of negative eating attitudes was found amongst screened participants with high risk of ED. Individual intention overrides all other determinants for abnormal eating. Moreover, evidence suggests that westernization may attribute to ED, supporting the view that ED are culturally bound. The differing stakeholders' views, together with other data found in this study, allow a number of recommendations for increasing awareness and identification of ED in Sudan.

    Full Text Available Purpose: Most causes of childhood visual impairment are either treatable or preventable. Eye health education plays an important role in reducing avoidable causes of visual impairment as well as to help ensure a healthy and educated community. The main objective of this study was to assess the Knowledge, Attitudes and Practices of the students and their parents on childhood eye services and barriers for accessing child eye care. Methods: The study was conducted in South Darfur State of Sudan between January and February 2015. Both quantitative and qualitative methods were used to collect data from eight secondary schools. Four schools for boys and four schools for girls were randomly selected from a list of 21 districts of South Darfur State and the Knowledge, Attitudes and Practices surveys were conducted with the students to collect quantitative data. In addition, seven focus group discussions were conducted with the children’s parents to collect qualitative data. Results: The majority (57.5% of the students reported that they knew about refractive error; however, 33.07% reported never hearing about refractive error. About 70.3% of the respondents believed that uncorrected refractive error leads to visual impairment, 21% believed refractive error did not cause visual impairment and 30.5% reported that wearing spectacles was not effective in the treatment of refractive error. With regard to the information about eye healthcare, 88.1% of the participants reported they did not have enough information about eye care. The reported need for more information about prevention, treatment and symptoms was 34.0%, 31.4% and 17.5%, respectively. With regard to barriers, 80.6% of the students reported never having had their eyes tested. The most cited barriers were cost, fear of wearing spectacles and fear of an eye examination. In addition, 72.6% of students reported that their health insurance did not cover eye care services. Most (53.6% of the parents

    Conflict in North Darfur state, Western Sudan started in 2003, and the delivering of curative health services was becoming a greater challenge for the country's limited resources. NGOs have played an important role in providing curative health services. To examine the role that Non-Governmental Organizations (NGOs) have played in providing curative health services, as well as to identify the difficulties and challenges that affect NGOs in delivering curative health services. Secondary data was collected from different sources, including government offices and medical organizations in Sudan and in North Darfur state. Primary data was obtained through interviews with government and NGOs representatives. The interviews were conducted with (1) expatriates working for international NGOs (N=15) (2) health professionals and administrators working in health sector (N= 45) in the period from November 2010 to January 2011. The government in North Darfur state spent 70% of its financial budget on security, while it spent it less than 1% on providing health services. The international NGOs have been providing 70% of curative health services to the State's population by contributing 52.9% of the health budget and 1 390 health personnel. Since 2003 NGOs have provided technical assistance to the health staff. As a result, more than fifty nurses have been trained to provide care and treatment, more than twenty-three doctors have been trained in laboratory equipment operation, and approximately six senior doctors and hospital directors have received management training. NGOs have been managing and supporting 89 public health facilities, and established 24 health centres in IDP camps, and 20 health centres across all the districts in North Darfur state. The NGOs have played an important role in providing curative health services and in establishing good health facilities, but a future problem is how the government will run these health facilities after a peaceful settlement has been

    Raman spectroscopy combined with multivariate analysis was evaluated as a tool for detecting Sudan I dye in culinary spices. Three Raman modalities were studied: normal Raman, FT-Raman and SERS. The results show that SERS is the most appropriate modality capable of providing a proper Raman signal when a complex matrix is analyzed. To get rid of the spectral noise and background, Savitzky-Golay smoothing with polynomial baseline correction and wavelet transform were applied. Finally, to check whether unadulterated samples can be differentiated from samples adulterated with Sudan I dye, an exploratory analysis such as principal component analysis (PCA) was applied to raw data and data processed with the two mentioned strategies. The results obtained by PCA show that Raman spectra need to be properly treated if useful information is to be obtained and both spectra treatments are appropriate for processing the Raman signal. The proposed methodology shows that SERS combined with appropriate spectra treatment can be used as a practical screening tool to distinguish samples suspicious to be adulterated with Sudan I dye.

    The Khor Arbaat basin is the main source of potable water supply for the more than 750,000 inhabitants of Port Sudan, eastern Sudan. The variation in hydraulic conductivity and storage capacity is due to the heterogeneity of the sediments, which range from clay and silt to gravely sand and boulders. The water table rises during the summer and winter rainy seasons; it reaches its lowest level in the dry season. The storage capacity of the Khor Arbaat aquifer is estimated to be 21.75 × 106 m3. The annual recharge through the infiltration of flood water is about 1.93 × 106 m3. The groundwater recharge, calculated as underground inflow at the ‘upper gate’, is 1.33 × 105 m3/year. The total annual groundwater recharge is 2.06 × 106 m3. The annual discharge through underground outflow at the ‘lower gate’ (through which groundwater flows onto the coastal plain) is 3.29 × 105 m3/year. Groundwater discharge due to pumping from Khor Arbaat basin is 4.38 × 106 m3/year on average. The total annual groundwater discharge is about 4.7 × 106 m3. A deficit of 2.6 × 106 m3/year is calculated. Although the total annual discharge is twice the estimated annual recharge, additional groundwater flow from the fractured basement probably balances the annual groundwater budget since no decline is observed in the piezometric levels.

    Bovine tuberculosis (BTB) is a widespread zoonosis in developing countries but has received little attention in many sub-Saharan African countries including Sudan and particularly in some parts such as Darfur states. This study aimed to detect bovine tuberculosis among caseous materials of cattle slaughtered in abattoirs in South Darfur State, Sudan by using microscopic and PCR-based methods. The study was a cross-sectional abattoir-based study which examined a total of 6,680 bovine carcasses for caseous lesions in South Darfur State between 2007 and 2009. Collected specimens were examined for the presence of acid-fast bacilli (AFB) by using microscopic and culture techniques. Isolated mycobacteria were identified by selected conventional cultural and biochemical tests in comparison to a single tube multiplex PCR (m-PCR) assay which detect Mycobacterium bovis-specific 168-bp amplicons. Of the total 6,680 slaughtered cattle examined in South Darfur, 400 (6 %) showed caseations restricted to lymph nodes (86.8 %) or generalized (13.2 %). Bovine tuberculosis was diagnosed in 12 (0.18 %), bovine farcy in 59 (0.88 %), unidentified mycobacteria in 6 (0.09 %), and missed or contaminated cultures in 7 (0.1 %). Out of 18 cultures with nonbranching acid-fast rods, 12 amplified unique 168-bp sequence specific for M. bovis and subsequently confirmed as M. bovis. With the exception of the reference M. tuberculosis strains, none of the remaining AFB amplified the 337-bp amplicon specific for M. tuberculosis. It could be concluded that bovine tuberculosis is prevalent among cattle in South Darfur representing 4.5 % from all slaughtered cattle with caseous lesions. The study sustains microscopy as a useful and accessible technique for detecting AFB. m-PCR assay proved to be valuable for confirmation of BTB and its differentiation from other related mycobacteriosis, notably bovine farcy.

    Full Text Available In Sudan pests and diseases are the major problem of vegetables production. Tomato crop is considered as the most important vegetable crop in the country according to its economic and nutrition value. There are many pest and diseases retarding tomato production such as whitefly, American bollworm, TYLCV and powdery mildew. Therefore some IPM options for tomato and onion were validated in FFS in order to help farmers in controlling the most important pests and diseases. The main objective of this study was to determine the impact of FFS on farmer's adoption of IPM options for tomato in the Gezira State, Sudan. Field survey was used to collect data from three Farmer Field Schools in the Gezira State namely: Um Dagarsi, Hantoub and Faris in the 2009/2010 growing season. All FFS participants were used, i.e. 30 FFS- participants from each school. Equal number of non-FFS participants (90 was used for comparison, by using the simple random sampling technique. The collected data were statistically analyzed and interpreted using percentage, frequency distribution and chi-square test. The results showed that the FFS schools were positively affected farmer's adoption of IPM options for tomato. It can be concluded that the FFS approach is very efficient in the transfer of farm technology for vegetable farmers through their participation in various activities of FFS schools. Thus, FFS approach must become national policy, share authority of extension organizations in control and execution of FFS activities with farmer unions for more effective participations of clientele in all activities of the schools and More efforts should be exerted in distribution of all inputs to farmers with reasonable prices through various agricultural centres.

    Full Text Available In order to decrease the prevalence of trachoma within the country, the Republic of South Sudan has implemented components of the SAFE strategy in various counties since 2001. Five counties in Eastern Equatoria state were surveyed in order to monitor progress of programmatic interventions and determine if additional rounds of Mass Drug Administration with azithromycin were needed.Five counties (Budi, Lafon, Kapoeta East, Kapoeta South and Kapoeta North were surveyed from April to October 2015. A cross-sectional, multi-stage, cluster-random sampling was used. All present, consenting residents of selected households were examined for all clinical signs of trachoma using the World Health Organization (WHO simplified grading system. 14,462 individuals from 3,446 households were surveyed. The prevalence of trachomatous inflammation-follicular (TF in children ages one to nine years ranged from 17.4% (95% Confidence Interval (CI: 11.4%, 25.6% in Budi county to 47.6%, (95% CI: 42.3%, 53.0% in Kapoeta East county. Trachomatous trichiasis (TT was also highly prevalent in those 15 years and older, ranging between 2.6% (95% CI: 1.6%, 4.0% in Kapoeta South to 3.9% (95% CI: 2.4%, 6.1% in Lafon. The presence of water and sanitation were low in all five counties, including two counties which had a complete absence of latrines in all surveyed clusters.To our knowledge, these were the first trachoma surveys conducted in the Republic of South Sudan since their independence in 2011. The results show that despite years of interventions, four of the five surveyed counties require a minimum of five additional years of SAFE strategy implementation, with the fifth requiring at minimum three more years.

    In the Sudan, Schistosoma mansoni infections are a major cause of morbidity in school-aged children and infection rates are associated with available clean water sources. During infection, immune responses pass through a Th1 followed by Th2 and Treg phases and patterns can relate to different stages of infection or immunity. This retrospective study evaluated immunoepidemiological aspects in 234 individuals (range 4-85 years old) from Kassala and Khartoum states in 2011. Systemic immune profiles (cytokines and immunoglobulins) and epidemiological parameters were surveyed in n = 110 persons presenting patent S. mansoni infections (egg+), n = 63 individuals positive for S. mansoni via PCR in sera but egg negative (SmPCR+) and n = 61 people who were infection-free (Sm uninf). Immunoepidemiological findings were further investigated using two binary multivariable regression analysis. Nearly all egg+ individuals had no access to latrines and over 90% obtained water via the canal stemming from the Atbara River. With regards to age, infection and an egg+ status was linked to young and adolescent groups. In terms of immunology, S. mansoni infection per se was strongly associated with increased SEA-specific IgG4 but not IgE levels. IL-6, IL-13 and IL-10 were significantly elevated in patently-infected individuals and positively correlated with egg load. In contrast, IL-2 and IL-1β were significantly lower in SmPCR+ individuals when compared to Sm uninf and egg+ groups which was further confirmed during multivariate regression analysis. Schistosomiasis remains an important public health problem in the Sudan with a high number of patent individuals. In addition, SmPCR diagnostics revealed another cohort of infected individuals with a unique immunological profile and provides an avenue for future studies on non-patent infection states. Future studies should investigate the downstream signalling pathways/mechanisms of IL-2 and IL-1β as potential diagnostic markers in order to

    Full Text Available Abstract Background The maternal mortality ratio in Sudan was estimated at 750/100,000 live births. Sudan was one of eleven countries that are responsible for 65% of global maternal deaths according to a recent World Health Organization (WHO estimate. Maternal mortality in Kassala State was high in national demographic surveys. This study was conducted to investigate the causes and contributing factors of maternal deaths and to identify any discrepancies in rates and causes between different areas. Methods A reproductive age mortality survey (RAMOS was conducted to study maternal mortality in Kassala State. Deaths of women of reproductive age (WRA in four purposively selected areas were identified by interviewing key informants in each village followed by verbal autopsy. Results Over a three-year period, 168 maternal deaths were identified among 26,066 WRA. Verbal autopsies were conducted in 148 (88.1% of these cases. Of these, 64 (43.2% were due to pregnancy and childbirth complications. Maternal mortality rates and ratios were 80.6 per 100,000 WRA and 713.6 per 100,000 live births (LB, respectively. There was a wide discrepancy between urban and rural maternal mortality ratios (369 and 872100,000 LB, respectively. Direct obstetric causes were responsible for 58.4% of deaths. Severe anemia (20.3% and acute febrile illness (9.4% were the major indirect causes of maternal death whereas obstetric hemorrhage (15.6%, obstructed labor (14.1% and puerperal sepsis (10.9% were the major obstetric causes. Of the contributing factors, we found delay of referral in 73.4% of cases in spite of a high problem recognition rate (75%. 67.2% of deaths occurred at home, indicating under utilization of health facilities, and transportation problems were found in 54.7% of deaths. There was a high illiteracy rate among the deceased and their husbands (62.5% and 48.4%, respectively. Conclusions Maternal mortality rates and ratios were found to be high, with a wide

    Full Text Available Exposure to natural sources of radiation, especially 222Rn and its short-lived daughter products has become an important issue throughout the world because sustained exposure of humans to indoor radon may cause lung cancer. The indoor radon concentration level and radon effective dose rate were carried out in the dwellings of Medani, El Hosh, Elmanagil, Haj Abd Allah, and Wad Almahi cities, Gezira State - Central Sudan, in 393 measurements, using passive integrated solid-state nuclear track devices containing allyl diglycol carbonate plastic detectors. The radon concentration in the corresponding dwellings was found to vary from (57 ± 8 Bq/m3 in Medani to 41 ± 9 Bq/m3 in Wad Almahi, with an average of 49 ± 10 Bq/m3. Assuming an indoor occupancy factor of 0.8 and 0.4 for the equilibrium factor of radon indoors, we found that the annual effective dose rate from 222Rn in the studied dwellings ranges from 1.05 to 1.43 mSv per year and the relative lung cancer risk for radon exposure was 1.044%. In this research, we also correlated the relationship of radon concentration and building age. From our study, it is clear that the annual effective dose rate is larger than the “normal” background level as quoted by UNSCEAR, lower than the recommended action level of ICRP, and less than the maximum permissible dose defined by the International Atomic Energy Agency.

    Full Text Available A reverse transcription-polymerase chain reaction (RT-PCR was used to amplify 1412 bp of the fusion protein gene (F gene of four Newcastle disease virus (NDV isolates; two velogenic (TY-1/90 and DIK-90 and two lentogenic isolates (Dongla 88/1 and GD.S.1. Following sequencing, nucleotide sequences were annotated and 894 bp were compared phylogenetically with those from strains previously reported in the Sudan and the virus strains published on the GenBank. It could be demonstrated that TY-1/90 and DIK-90 strains belong to the genotype VI of NDV and are in close genetic relationship to sub- genotype VIb. TY-1/90 and DIK-90 strains were observed to be genetically unrelated to the earlier Sudanese isolates of 1970/80s and the late of 2000s suggesting a different origin. The close genetic relationship to the European and African pigeon paramyxovirus type 1 (PPMV-1 suggests a common ancestor. Dongola, GD.S.1 strains were classified into genotype II that comprises non-pathogenic lentogenic NDV strains. The present genetic classification of NDV isolates of the Sudan provides valuable information on genotypes of NDV. Further molecular epidemiological investigations of the recent outbreaks of Newcastle disease in the Sudan are needed in order to improve the efficiency of control strategies and vaccine development.

    Full Text Available Water rather than land is the limiting factor for crop production in Sudan. This study attempts to use the water footprint (WFP and virtual water concepts to account for crops water consumption under the Sudanese rainfed and irrigated conditions. The general average of the green WFP of sorghum and millet were found to be about 7700 and 10700 m3 ton-1, respectively. According to experimental results at three different climates, in-situ rainwater harvesting techniques could reduce the WFP of rainfed sorghum by 56% on the average. The blue component (surface water shows the highest contribution to the total WFP of irrigated crops: 88% for cotton, 70% for sorghum, 68% for groundnut and 100% for wheat. However, the role of the green water (rainwater is not marginal since it largely influences the operation and maintenance (silt clearance of the gravity-fed irrigation system. Under normal conditions, the annual total virtual water demand of sorghum (the dominant food crop in Sudan is found to be 15 km3, of which 91% is green water. During a dry year, however, Sudan could experience a deficit of 2.3 km3 of water, necessitating the adoption of a wise food stocking-exporting policy.

    In this study blood samples were collected from 665 female from Northern State of Sudan, 606 of those females are married and only 59 females are singles. These samples were used to estimate the normal CA 15-3 which was found to be similar to the international one and that is ranged from zero to 35 mlu/ml. When the same techniques were used using samples collected from patients who have been clinically diagnosed as breast cancer, CA 15-3 levels were found to be higher in most of these samples and the other finding is that the risk of getting breast cancer is starting from age 25 years. On the other hand , 650 males were participated in this study to estimate normal value of PSA, of them 553 were married. And again the levels estimated for this marker was found to be the same as that used globally which is ranged from zero to four ng/ml. When blood samples from prostate patients were assayed for PSA, the results showed high levels of this marker in almost all the samples as expected but the important finding is that prostate cancer is age depend. At the end of the project, many recommendations highlighted to be considered in the near future.(Author)

    The objective of this study is to develop a digital GIS model; that can evaluate, predict and visualize carbon monoxide (CO) levels in Khartoum state. To achieve this aim, sample data had been collected, processed and managed to generate a dynamic GIS model of carbon monoxide levels in the study area. Parametric data collected from the field and analysis carried throughout this study show that (CO) emissions were lower than the allowable ambient air quality standards released by National Environment Protection Council (NEPC-USA) for 1998. However, this pilot study has found emissions of (CO) in Omdurman city were the highest. This pilot study shows that GIS and geostatistical modeling can be used as a powerful tool to produce maps of exposure. (authors)

    The purpose of this study is to evaluate the Quality Assurance procedures in the Military Corps in Khartoum state, through the comprehensive Quality Control QC procedures of the x-ray machines and darkrooms in the x-ray departments, and to provide a Quality Assurance Manual to support the federal ministry of Health running QA program. This study is the first time that the departments of the Military Corps apply QC tests on their x-ray machines. The total number of x-ray machines in Khartoum state is 10 machines with 4 darkrooms. Only three of the x-ray machines are tested and the results showed that there are unacceptable parameters of the major exposure factors which determine the image quality. The percentage of accuracy defects are 67% for kVp Accuracy, 67% for Time Accuracy, 33% for Relative mA Linearity, 33% for Relative mAs Linearity, 67% for kVp Reproducibility, 67% for Collimator test. Also the tested darkrooms showed that the percentage of unacceptable parameters as: 15% for tested intensifying screens, 18% for tested Cassettes, 100% for light leakage, 67% for Safelight. Reject film Analysis showed that 5.3% and 10% is the reject percentage during four months for the main and casualty centers respectively. Personal monitoring records showed that the dose is within the dose limits the maximum and minimum Dose equivalent in 2001 is 4.231 Sv, 0.154 Sv and in 2002 is 2.736 Sv, 0.167 Sv consequently, and the monitoring has been stopped since July 2002. Also the study reveals that only 4% from the total cost of the x-ray machines owned by the mentioned hospitals is the price of the QC test tools equipments. The study gives a review of all definitions and QC procedures needed for the QA manual and can be referenced as a QA Manual for the Military Corps or any other hospital.

    Full Text Available Background: Global estimates suggest there are almost 19 million visually impaired children worldwide, the major cause being uncorrected refractive error (RE. Aim: To assess the prevalence of visual impairment (VI and RE among Sudanese school-aged children. Setting: Eight randomly selected primary schools from 21 districts in South Darfur State of Sudan were involved. Methods: A school-based cross-sectional study of RE and VI in primary schoolchildren from grades 1 to 8 (children aged 6–15 years was investigated. A Refractive Error Study in Children (RESC protocol was implemented to determine the prevalence of RE and VI in these schoolaged children. Participants were enrolled through stratified multistage cluster sampling of four all-male and four all-female primary schools from South Darfur State of Sudan. Examination procedures followed the RESC protocol, which included visual acuity (VA measurements, binocular vision assessments, retinoscopy and autorefraction under cycloplegia, as well as examination of the external eye, anterior-segment, media and fundus. Results: A total of 1775 children were invited to participate in the study and 1678 were examined resulting in a participation rate of 94.5%. The findings indicated that the prevalence of uncorrected, presenting and best-corrected VA of 6/12 or worse was 6.4% (95% confidence interval [CI], 4.9–7.9, 4.4% (95% CI, 2.9–5.9 and 1.2% (95% CI, 0.3–2.7 respectively. RE was the cause of VI in 57% of participants, retinal disorders in 13.1%, amblyopia in 5.6%, corneal opacity in 0.9%, cataract in 3.7%, with the causes of reduced vision undetermined in 10.3% and various other causes contributed 9.3%. External and anterior-segment abnormalities were observed in 10.2% of children. This was mainly allergic conjunctivitis (5.3% followed by bacterial and viral conjunctivitis (4.2%. The prevalence of myopia (≥|-0.50 D| in one or both eyes was 6.8% (95% CI, 5.3–8.3, hypermetropia (≥ 2 D was

    Material and methods: A total of 300 serum samples were taken from jugular veins of cattle and screened by Rose Bengal Plate Test (RBPT and Serum Agglutination Test (SAT. The RBPT-positive samples were all tested using c-ELISA. Results: Antibodies were detected with an overall seroprevalence of 25.7% using RBPT and 22.7% using SAT while slightly less than two thirds of the RBPT-positive samples were cELISA-positive. The herd and within-herd seroprevalences were 76.7% (n=23 and from 10.0-80.0%. Moreover, significant statistical dissimilarities were not observed between the seroprevalence of the different categories of the investigated risk factors by RBPT. Only milking method ( and #967;2=3.976; P=0.046 was found to have an influence on the RBPT-positive status for brucella infection in the univariate analysis. Additionally, natural breeding (OR=3.61; 95% CI 1.192 and ndash;10.96; P=0.023 was the only observed risk factor with an increased odd of being RBPT positive. The Kappa analysis showed an almost perfect agreement between the results of the RBPT and the SAT tests. Conclusion: The prevalence of anti-brucella antibodies in Khartoum state was relatively higher; therefore, brucellosis in cattle is, perhaps, a significant public health problem. It is recommended to raise awareness of cattle owners and/or herders on the routes of transmission of brucellosis. [J Adv Vet Anim Res 2016; 3(2.000: 134-144

    To determine whether pre-emptive oral cholera vaccination reduces disease severity and mortality in people who develop cholera disease during an outbreak. The study involved a retrospective analysis of demographic and clinical data from 41 cholera treatment facilities in South Sudan on patients who developed cholera disease between 23 April and 20 July 2014 during a large outbreak, a few months after a pre-emptive oral vaccination campaign. Patients who developed severe dehydration were regarded as having a severe cholera infection. Vaccinated and unvaccinated patients were compared and multivariate logistic regression analysis was used to identify factors associated with developing severe disease or death. In total, 4115 cholera patients were treated at the 41 facilities: 1946 (47.3%) had severe disease and 62 (1.5%) deaths occurred. Multivariate analysis showed that patients who received two doses of oral cholera vaccine were 4.5-fold less likely to develop severe disease than unvaccinated patients (adjusted odds ratio, aOR: 0.22; 95% confidence interval, CI: 0.11-0.44). Moreover, those with severe cholera were significantly more likely to die than those without (aOR: 4.76; 95% CI: 2.33-9.77). Pre-emptive vaccination with two doses of oral cholera vaccine was associated with a significant reduction in the likelihood of developing severe cholera disease during an outbreak in South Sudan. Moreover, severe disease was the strongest predictor of death. Two doses of oral cholera vaccine should be used in emergencies to reduce the disease burden.

    Full Text Available Objective: This study aimed to determine the prevalence and assess antimicrobial susceptibility of extended- spectrum β-lactamase-producing Escherichia coli isolated from clinical specimens of patients at hospitals in Khartoum State, Sudan.Methods: During April to August 2011, a total of 232 E. coli isolates were collected from various clinical specimens of patients. Isolates were identified, tested for antimicrobial susceptibility and screened for ESBL production as per standard methods. The double-disk diffusion method was used to confirm ESBL production using antimicrobial disks of ceftazidime (30 μg, cefotaxime (30 μg, with or without clavulanic acid (10 μg. A zone difference of >5 mm between disks was considered indicative of ESBL production.Results: Out of 232 E. coli isolates, 70 (30.2% were found to be positive for ESBL by the applied phenotypic methods. ESBL-producing isolates yielded high resistance rates for trimethoprim-sulfamethoxazole (98.6%, tetracycline (88.6%, nalidixic acid (81.4% and ciprofloxacin (81.4%. The highest antimicrobial activities of ESBL-producing isolates were observed for amikacin (95.7%, followed by tobramicin (74.3% and nitrofurantoin (68.6%. Resistance to quinolones, aminoglycosides, trimethoprim-sulfamethoxazole, tetracycline, nitrofurantoin and chloramphenicol was higher in ESBL than non-ESBL isolates (p<0.05. The frequency of ESBL-producing isolates varied among hospitals (18.2% to 45.1%, although a high prevalence was recorded as 45.1% at Khartoum Teaching Hospital. Wound specimens were the most common source of ESBL-producing isolates. The proportion of ESBL-producing E. coli did not differ significantly between adults and children (31% vs. 27%.Conclusion: The prevalence of ESBL-producing E. coli detected in this study is of great concern, which requires sound infection control measures including antimicrobial management and detection of ESBL-producing isolates.

To document and measure health-related activities executed by an international nongovernmentalo rganisation to sustainably strengthen the capacity of the health system in delivering essential health services to pregnant women and children under two years of age, including new-borns and infants. A range of mixed methods, including in-depth interviews, focus group discussions, observation, and uncontrolled cross-sectional before-and-after surveys using Henderson’s method were carried out. The unit of analysis was mothers of children under two years of age, and community health workers (CHWs. An estimated 39 000 children under age two were attended to by CHWs. Coverage of essential maternal and childhealth care (MCH increased in all single interventions, ranging from a minimum of 5% points to a maximum of 49% points during the implementation period. The capacity of the health system to deliver essential MCH services improved by building the supply and performance of the health workforce through task-shifting and in-service training. Likewise, operational linkages between community structures and local health services were strengthened. In conclusion, this program supported health system strengthening, mainly in the areas of service delivery, health workforce, and medical products, vaccines, and technologies. The project also informed policy at district and national levels and repositioned the maternal, neonatal, and child health (MNCH agenda to further scale up these activities. An evaluation of a four year USAID-funded child survival project implemented by an international non-governmental organisation (NGO in fragile-state context showed progress and challenges in health system strengthening for maternal health practices and community case management of diarrhoea, pneumonia, and

    The causes of cancer in River Nile state are differ between environmental and radiological, this paper tried to make comparison between the two causes, to determine the real cause behind the large rising of cancer cases in this state, considering the daily habits for the patients and the possible contamination in the natural resources around them. The noticeable thing that most of cancer cases are might be due to the high concentration of nitrate pollutant detected in natural resources such as drinking water; also by looking to the radioactive elements we see there's high concentration of some radioactive elements specially the K-40 which found in Portulaca Oleracea.

    In the present study, air samples have been collected from different areas in Khartoum and River Nile States. Sample collection was performed over different periods of time (1-2 hours). The average elemental concentrations for Ca, Cr, Fe, Co, Ni, Br and Pb have been determined using energy dispersive x-ray fluorescence (EDXRF). The accuracy of measurements has been investigated by using Standard Reference Material (SRM) IAEA- Soil-7. In Khartoum State, the average elemental concentrations of Ca, Cr, Fe, Co, Ni, Br and Pb in the expected contaminated sites were 83.27, 0.001, 36.12, 14.051, 0.1, 7.057 and 11.122 μg/m 3 , respectively. In River Nile State proposed contaminated sites the average elemental concentrations of Ca, Cr, Fe, Co, Ni, Br and Pb were 19.387, 3 , respectively. The results showed that higher values were found for the crustal elements (Ca, Fe) while lower values were found for the elements emitted from other sources. Enrichment factors were calculated for the elements which showed that the elements Ca, Cr and Ni were not enriched, while Pb and Co were enriched possibly through anthropogenic emission. A ratio of Br/Pb in aerosol similar to the ratio in the petrol burned is indicative of a source of both lead and bromine.(Author)

    Full Text Available In the Sudan, Schistosoma mansoni infections are a major cause of morbidity in school-aged children and infection rates are associated with available clean water sources. During infection, immune responses pass through a Th1 followed by Th2 and Treg phases and patterns can relate to different stages of infection or immunity.This retrospective study evaluated immunoepidemiological aspects in 234 individuals (range 4-85 years old from Kassala and Khartoum states in 2011. Systemic immune profiles (cytokines and immunoglobulins and epidemiological parameters were surveyed in n = 110 persons presenting patent S. mansoni infections (egg+, n = 63 individuals positive for S. mansoni via PCR in sera but egg negative (SmPCR+ and n = 61 people who were infection-free (Sm uninf. Immunoepidemiological findings were further investigated using two binary multivariable regression analysis.Nearly all egg+ individuals had no access to latrines and over 90% obtained water via the canal stemming from the Atbara River. With regards to age, infection and an egg+ status was linked to young and adolescent groups. In terms of immunology, S. mansoni infection per se was strongly associated with increased SEA-specific IgG4 but not IgE levels. IL-6, IL-13 and IL-10 were significantly elevated in patently-infected individuals and positively correlated with egg load. In contrast, IL-2 and IL-1β were significantly lower in SmPCR+ individuals when compared to Sm uninf and egg+ groups which was further confirmed during multivariate regression analysis.Schistosomiasis remains an important public health problem in the Sudan with a high number of patent individuals. In addition, SmPCR diagnostics revealed another cohort of infected individuals with a unique immunological profile and provides an avenue for future studies on non-patent infection states. Future studies should investigate the downstream signalling pathways/mechanisms of IL-2 and IL-1β as potential diagnostic markers

    The dental professions hold an important responsibility in the control of oral cancer and the early diagnosis highly depends on their knowledge. The present study was developed to assess the knowledge, attitude, and practice of dentists in Khartoum State regarding oral cancer prevention and early detection. An administered questionnaire was structured and sent to all licensed 130 dentists working in public dental clinics in Khartoum State. Responses to the questionnaire were analyzed using descriptive and analytical statistics. Although the majority of the dentists were knowledgeable about the major risk factors of oral cancer, more than half of the dentists reported they do not carry out any special examination to detect oral cancer in age 40 and above in asymptomatic patients. Dentists indicated their lack of training as the main barrier for conducting a comprehensive oral cancer examination. Interestingly, the vast majority of the dentists express their interest to have further oral cancer educational and training sessions. The findings of the present study suggested strongly that educational and training interventions are necessary to enhance preventive measures which may lead to reduce mortality and morbidity from oral cancer.

    Yellow fever (YF) is a vector-borne disease transmitted to humans by infected Aedes mosquitoes, while hepatitis E virus (HEV) is a waterborne disease that is transmitted through the fecal-oral route. Both diseases have very close clinical presentation, namely fever, jaundice, malaise, and dark urine; they differ in severity and outcome. In this cross-sectional, laboratory-based study, an attempt was made to measure the correlation of concomitant YF and HEV infection in Darfur States during the previous YF outbreak in 2012. Results found concomitant outbreaks of YF and HEV at the same time with very weak statistical correlation between the two infections during the outbreak period, with Cramer's V correlation 0.05 and insignificant p value of 0.86. This correlation indicates that clinicians and care providers in tropical areas have to deal with clinical case definitions used for disease surveillance very carefully since prevalence of HEV infection is relatively common and this increases the possibility of misclassification and missing YF cases, particularly initial index cases, in a season or outbreak.

    Full Text Available Aim: This study was conducted in dairy cattle in Nyala, South Darfur State, during the period from June to September 2015, to study the prevalence of bovine tropical theileriosis. Materials and Methods: Apparently, healthy cattle of different age groups, different breeds, and from both sexes were randomly selected from seven locations. Three age groups of cattle were selected, group one <1 year old, group two 1-3 years old, and group three older than 3 years. These cattle were indigenous and cross (Friesian X zebu. A total of 150 blood samples were collected for blood smears, blood in EDTA tubes, and serum samples as well as ticks infesting cattle. Three diagnostic techniques were used such as blood smear, indirect fluorescent antibody test (IFAT, and polymerase chain reaction (PCR. Results: Of 150 samples, 11 (7.3%, 95% confidence interval [CI]: 9.1-5.5 were positive for Theileria spp. piroplasms in the blood smears, 70 (46.7%, 95% CI: 35.7-57.7 were positive for Theileria annulata antibodies in the IFAT, and of 100 samples, 39 (39%, 95% CI: 46.6-31.4 were positive for T. annulata using PCR. The prevalence of T. annulata was higher in indigenous breed than cross cattle by the three diagnostic techniques. The highest prevalence of T. annulata was recorded among cattle older than 3 years old. There were three genera and ten species of ticks found feeding on cattle. These were Rhipicephalus evertsi evertsi, Rhipicephalus decoloratus, Rhipicephalus annulatus, Hyalomma dromedrii, Hyalomma impeltatum, Hyalomma rufipes, Hyalomma anatolicum, Hyalomma truncatum, Amblyomma variegatum, and Amblyomma lepidum. Conclusion: The study concluded that tropical theileriosis is prevalent among dairy cattle in Nyala. H. anatolicum was found in very low numbers, suggesting other ticks may play a role in the transmission of the disease. Molecular characterization of T. annulata is recommended for accurate mapping of the disease and evaluates the magnitude problem of

    A cross sectional study was conducted in Khartoum State. A total of 45 males' traffic policemen were divided into two groups according to exposure to car exhaust; n=30 taken as exposed group, n=15 taken as controls, who were not exposed to car exhaust. The study was conducted to determine lead concentrations in traffic ambient air, to determine lead levels in blood of traffic policemen, and to evaluate the effect of exposure to car exhaust on traffic policemen during January 2009. The level of lead in ambient air was determined in 14 locations which were taken randomly at the intersections and entrances to the bridges using personal sampler "Cassella, U.K". The blood samples of all policemen were analyzed by atomic absorption Spectrophotometer to determine lead levels. A questionnaire was designed to assess the adverse health effects on the traffic policemen. The degree of environmental lead pollution in traffic ambient air was found to be 0.1937 +/- 0.1768 mg/m3 with range between 0.000-0.5166 mg/m3. In seven locations out of fourteen locations lead concentrations were 0.1940 and 0.5166 above the permissible level of 0.15 mg/m3 permitted internationally. Blood lead levels on traffic policemen (exposed and control groups) were found to be 2.4691 +/- 1.4065 microg/100 ml and 0.3944 +/- 1.2471 microg/100 ml respectively and there is no significant differences between the two groups where using SPSS program. A questionnaire findings were: average age mean of 35.9 +/- 7.7 years, 47.48% worked for periods of more than 20 years, 74.19% did not work before joining the traffic police, 51.6% of them recognized traffic air pollution as a problem of high level, 45.2% of them estimated it as medium, and 3.2% as low. As habits 38.71% were smokers, and for health complaints, 61.29% have various complaints of headache, fatigue, abdominal, hypertension and anemia.

    Full Text Available There have been recent incidences of weather extremes in the West African Sudan Savanna and farmers have responded through implementation of relevant adaptation strategies. For a deeper insight into farmers’ adaptation to climatic shocks, this study documents farmers’ perception of recent changes in the local climate, and identifies factors that influence the number and choice of strategies implemented. Interdependencies among strategies are explored and joint and marginal probabilities of adoption estimated. Upper East Ghana and Southwest Burkina Faso are used as the case study regions. These regions were selected due to extreme reliance of inhabitants on agriculture for sustenance, and their recent exposure to weather extremes. Through estimation of a Poisson regression and multivariate probit model to identify the major factors that influence the number and choice of strategies adopted, we discover that, limited access to credit, markets, and extension services, smaller cropland area, and low level of mechanization could impede effective adaptation to weather extremes. To enhance farmers’ adaptive capacity, policy makers and various stakeholders need to contribute towards improving farmers’ access to credit, markets, and extension services, and implement measures to promote mechanization.

    Darfur region in western Sudan is located in one of the world's most inhospitable environments, adjacent to the Sahara desert, conflicts and drought have severely degraded this fragile area, devastating the environment, livestock and people. Northern Darfur is bedeviled with frequent drought due to insufficient water resources, high summer temperatures, and poor precipitation. Monitoring drought and providing timely seasonal predictions is important for integrated drought risk reduction in the region. This paper evaluates drought conditions in North Darfur by applying meteorological, remote sensing and crop production data, as well as the Driving force-Pressure-State-Impacts-Response (DPSIR) assessment framework. Interviews, group discussions and participant observations were conducted in order to understand the DPSIR framework indicators. The relationship between the Reconnaissance Drought Index (RDI), Vegetation Condition Index (VCI) and Soil Moisture Content Index (SMCI) were evaluated utilizing data from all five North Darfur counties during 10 growing seasons (2004-2013). Our results showed a strong correlation between RDI, VCI, and SMAI. Also, a significant agreement was noticed between Yield Anomaly Index (YAI) and Rainfall Anomaly Index (RAI). Generally, a high correlation coefficient was obtained between the meteorology drought index and remote sensing indices, which demonstrates the effectiveness of the above indices for evaluating agricultural drought in the sub-Saharan area. Keywords: Drought; Vegetation Condition Index; Reconnaissance Drought Index; Soil Moisture Content Index; North Darfur.

    Covalent organic polymers (COPs) connected by covalent bonds are a new class of porous network materials with large surface area and potential superiority in sample pretreatment. In this study, a new hydrazone linked covalent organic polymer (HL-COP) adsorbent was well-designed and synthesized based on a simple Schiff-base reaction. The condensation of 1,4-phthalaldehyde and 1,3,5-benzenetricarbohydrazide as organic building blocks led to the synthesis of HL-COP with uniform particle size and good adsorption performance. This HL-COP adsorbent with high hydrophobic property and rich stacking π electrons contained abundant phenyl rings and imine (CN) groups throughout the entire molecular framework. The adsorption mechanism was explored and discussed based on π-π affinity, hydrophobic effect, hydrogen bonding and electron-donor-acceptor (EDA) interaction, which contributed to its strong recognition affinity to target compounds. Enrichment factors were 305-757 for six Sudan dyes by HL-COP micro-solid phase extraction (μ-SPE), indicating its remarkable preconcentration ability. Furthermore, the adsorption amounts by HL-COP μ-SPE were 1.0-11.0 folds as those by three commonly used commercial adsorbents. Then, HL-COP was applied as adsorbent of online μ-SPE coupled with high performance liquid chromatography (HPLC) for enrichment and analysis of trace Sudan dyes in food samples with detection limit of 0.03-0.15μg/L. The method was successfully applied for online analysis of chilli powder and sausage samples. Sudan II and Sudan III in one positive chilli powder sample were actually found and determined with concentrations of 8.3 and 6.8μg/kg, respectively. The recoveries of chilli powder and sausage samples were in range of 75.8-108.2% and 73.8-112.6% with relative standard deviations of 1.2-8.5% and 1.9-9.4% (n=5), respectively. The proposed method was accurate, reliable and convenient for the online simultaneous analysis of trace Sudan dyes in food samples

    This study investigates the nature of the nitrate concentration and its effect on the quality of groundwater in the Bara basin in North Kordofan State Sudan. The principal objective of this study is to: detect possible NO 3 sources affecting groundwater quality. The δ 15 N results included two range of values, which suggested two different nitrogen sources in different parts of the study area. The data used in this study includes lithological logs, pumping and recovery data and chemical analysis. Rock ware, surfer, aquitest and aquichem software programs were used to analyze the data. which is the based on the lithological logs from nine shallow wells and seven deep boreholes. The geological formation was found to be the Umm Ruwaba formation which consists of two aquifers an upper shallow one and the other deep aquifer. The transmissivity of the upper aquifer was found to be 0.528m 2 / day, which is good and the average of hydraulic conductivity was found to be 0.08 4 m/ day, which is high and the storativity is 0.08 1 . The direction of flow of groundwater was found to be from North West to North East over all the area. Chemical analysis showed that the TDS concentration in the study area is within the permissible limits of the Sudanese and the WHO standards. The calcium concentration in the study area also found to be within the permissible limits of the Sudanese and the WHO standards. The nitrate concentration in the upper aquifer ranges between 9.68 and 891 mg/1 which is above the permissible limit of the Sudanese and the WHO standards. The water type in the upper aquifer was found to be calcium-nitrate-chloride-bicarbonate. It appears that the source of the calcium is either for the decay of dead animal bones or the dissolution of calcareous deposits within the upper aquifer. It can be concluded that the quality of groundwater in the study area is good for the human consumption. (Author)

    In late 2012 and in conjunction with South Sudan's Ministry of Health - National Malaria Control Program, PSI (Population Services International) conducted a comprehensive mapping exercise to assess geographical coverage of its integrated community case management (iCCM) program and consider scope for expansion. The operational research was designed to provide evidence and support for low-cost mapping and monitoring systems, demonstrating the use of technology to enhance the quality of programming and to allow for the improved allocation of resources through appropriate and need-based deployment of community-based distributors (CBDs). The survey took place over the course of three months and program staff gathered GPS (global positioning system) data, along with demographic data, for over 1200 CBDs and 111 CBD supervisors operating in six counties in South Sudan. Data was collated, cleaned and quality assured, input into an Excel database, and subsequently uploaded to geographic information system (GIS) for spatial analysis and map production. The mapping results showed that over three-quarters of CBDs were deployed within a five kilometer radius of a health facility or another CBD, contrary to program planning and design. Other characteristics of the CBD and CBD supervisor profiles (age, gender, literacy) were more closely matched with other regional programs. The results of this mapping exercise provided a valuable insight into the contradictions found between a program "deployment plan" and the realities observed during field implementation. It also highlighted an important need for program implementers and national-level strategy makers to consider the natural and community-driven diffusion of CBDs, and take into consideration the strength of the local health facilities when developing a deployment plan.

    2011-01-01

    Indoor air pollution from burning solid fuels for cooking is a major environmental health problem in developing countries, predominantly affecting children and women. Traditional household energy practices also contribute to substantial time loss and drudgery among households. While effective interventions exist, levels of investment to date have been very low, in part due to lack of evidence on economic viability. Between 2004 and 2007, different combinations of interventions – improved stoves, smoke hoods and a switch to liquefied petroleum gas – were implemented in poor communities in Nepal, Sudan and Kenya. The impacts were extensively evaluated and provided the basis for a household-level cost-benefit analysis, which essentially followed the methodology proposed by the World Health Organization. The results suggest that interventions are justified on economic grounds with estimated internal rates of return of 19%, 429% and 62% in Nepal, Kenya and Sudan, respectively. Time savings constituted by far the most important benefit followed by fuel cost savings; direct health improvements were a small component of the overall benefit. This paper describes the methodology applied, discusses the findings and highlights the methodological challenges that arise when a global approach is applied to a local programme. - Highlights: ► A project to alleviate indoor smoke from cooking fires in Sudan, Kenya and Nepal was evaluated. ► Investments for improving indoor air quality are shown to be justifiable on economic grounds. ► Savings in time and fuel costs, as well as health improvements are key benefits. ► The challenges of applying a global cost-benefit approach to a local programme are examined.

    Full Text Available Abstract Background Toombak is a form of smokeless tobacco, locally made and consumed in Sudan. It is associated with a number of health hazards, particularly oral cancer. This study was set out to assess the prevalence and socio-demographic distribution of its use, and to explore the socio-cognitive factors affecting the intention to use Toombak among secondary school students in Khartoum State, Sudan. Methods A cross-sectional school-based study was conducted in 2013–2014 where schools were randomly selected using a one-stage stratified sampling procedure. The sample size was calculated to consist of 1526 students. Data were collected through a self-administered questionnaire, which contained some cognitive constructs; information received, social image, attitudes, normative social influence, accessibility to Toombak, socio-demographics and Toombak use related variables. Results A total of 1670 secondary school students participated in the study. More than half of them 53.4% were <15-years-old and 53.6% were females. Only 5.3% of the students reported intention to use Toombak. Among the students 10.9% were ever Toombak users, 81.6% reported a positive attitude towards its use and 60.7% had received information about its harmful effects. A total of 72.6% reported normative social influence towards using Toombak and 62.5% perceived a negative social image attached to its use. Most of the students, 70.8% reported exposure to anti-Toombak information, 41.8% confirmed exposure to Toombak advertisement and 87.5% reported indirect access to its sale. Younger students reported ever use of Toombak less frequently than their older counterparts (38.4% versus 61.6%, p < 0.001. Males reported ever use of Toombak more frequently than did females (74.3% versus 25.7%, p < 0.001. According to the regression model, individuals who perceived a positive social image of Toombak users and had past experience were more likely to intend to its use. Conclusions

    Multivariate statistical techniques are efficient ways to display complex relationships among many objects. An attempt was made to study the radioactive data in two types of Sudanese phosphate deposits; Kurun and Uro phosphate, using several multivariate statistical methods. Pearson correlation coefficient revealed that a U-238 distribution in Kurun phosphate is controlled by the variation of K-40 concentration, whereas in Uro phosphate it is controlled by the variation of U-235 and U-234 concentration. Histograms and normal Q–Q plots clearly show that the radioactive variables did not follow a normal distribution. This non-normality feature observed may be attributed to complicating influence of geological factors. The principal components analysis (PCA) gives a model of five components for representing the acquired data from Kurun phosphate, where 89.5% of the total variance is explained. A model of four components was sufficient to represent the acquired data from Uro phosphate, where 87.5% of the total data variance is explained. The hierarchical cluster analysis (HCA) indicates that U-238 behaves in the same manner in the two types of phosphates; it associated with a group of four radionuclides; U-234, Po-210, Ra-226, Th-230, which the most abundant radionuclides, and all belong to the uranium-238 decay series. Two parameters have been adapted for the direct differentiate between the two phosphates. Firstly, U-238 in Uro phosphate have shown higher degree of mobility (CV% = 82.6) than that in Kurun phosphate (CV% = 64.7), and secondly, the activity ratio of Th-230/Th-232 in Uro phosphate is nine times than that in Kurun phosphate. - Highlights: ► Multivariate statistical techniques were used to characterize radioactive data. ► U-238 in Uro phosphate shows higher degree of mobility (CV% = 82.6). ► U-238 in Kurun phosphate shows lower degree of mobility (CV% = 64.7). ► The radioactive variables did not follow a normal distribution. ► The ratio of Th

    An experiment was conducted at Merowe Research Station farm, in the Northern State, Sudan, during 2008/2009 and 2009/2010 seasons. The objectives of the experiment were to determine the damage inflicted by a wild sorghum species (Sorghum arundinaceum (Del.) Stapf. ) on the yield of faba bean (Vicia faba L.) and to evaluate the efficacy of the post-emergence herbicide clodinafop-propargyl (Topik) on wild sorghum and its effect on faba bean yield. The wild sorghum reduced faba bean crop stand and straw and seed yields by 53% - 76%, 76% - 79% and 88% - 91%, respectively, compared with the hand-weeded control. Faba bean was tolerant to the herbicide. The herbicide, at all rates, effected complete (100%) and persistent control of the wild sorghum and resulted in faba bean seed yield comparable to the hand-weeded control. The lowest dose (0.075 kg a.i/ha) of the herbicide used was equal to 75% of the dose recommended for the control of wild sorghum in wheat. It is concluded that clodinafop-propargyl at 0.075 kg a.e/ha could be used in controlling wild sorghum in faba bean. At this rate, the marginal rate of return was about 35 which indicating that every monetary unit (SDG 1) invested in the mentioned treatment would be returned back, plus additional amount of 35 SDG.(Author)

    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 (spices and are most likely a result of cross-contamination during preparation and storage and not intentional adulteration.

    The Sudan, along with all Sahelian countries, faces urgent environmental problems caused, in part, by the clear-cutting of scrub for firewood. Analyzes the economic consequences of a policy often proposed to reduce the consumption of firewood. Specifically, the authors simulate the policy of introducing more efficient wood burning stoves into households by using an Applied General Equilibrium (AGE) model. The results indicate that the anticipated reduction in the economy-wide demand for wood, based on the increase in the technical efficiency of the stoves, is not fully realized. 23 refs., 2 figs., 5 tabs

    In this study, surface soil and street dust samples were collected from Khartoum State, from areas exposed to industrial and traffic emission and from areas expected to be free from elemental emission to serve as control. Samples were digested using wet digestion method to determine the total concentration of Na, K, Cr, Mn, Fe, Cu, Zn and Pb using Atomic Absorption spectrophotometer (Aas), X-Ray fluorescence and flame photometer. Also samples were chemically fractionated using chemical specification method, and the solutions analyzed using Aas to determine the chemical form of the elements. Quality assurance of the data was achieved through the analysis of certified reference material. The range of the total concentration for Na, K, Mn, Fe, Cu, Zn and Pb are 400-5175, 220-4690, 0.07-315.25, 20-250, 2050.8-46000, 0.5-2305, 4.5-280, 9.5-6200 mg/kg respectively. results obtained agree with expected emission profile as inferred from the emitting source locations. Distribution of elements from emitting source locations and control samples in different chemical fractions was carried out, and the findings reinforced by enrichment factors calculations as well by the results obtained by statistical multi-variate analysis methods such as principle compared with previous literature.(Author)

    Absorption and fluorescence spectra of three Sudan dyes (SudanIII, SudanIV and Sudan black B) were recorded in various solvents with different polarity in the range of 300-800 nm, at room temperature. The solvatochromic method was used to investigate dipole moments of these dyes in ground and excited states, in different media. The solvatochromic behavior of these substances and their solvent-solute interactions were analyzed via solvent polarity parameters. Obtained results express the effects of solvation on tautomerism and molecular configuration (geometry) of Sudan dyes in solvent media with different polarity. Furthermore, analyze of solvent-solute interactions and value of ground and excited states dipole moments suggests different forms of resonance structures for Sudan dyes in polar and low-polar solvents.

    Located on the Bahr el Jebel in South Sudan, the Sudd is one of the largest floodplain wetlands in the world. Seasonal inundation drives the hydrologic, geomorphological, and ecological processes, and the annual flood pulse is essential to the functioning of the Sudd. Despite the importance of the flood pulse, various hydrological interventions are planned upstream of the Sudd to increase economic benefits and food security. These will not be without consequences, in particular for wetlands where the biological productivity, biodiversity, and human livelihoods are dependent on the flood pulse and both the costs and benefits need to be carefully evaluated. Many African countries still lack regional baseline information on the temporal extent, distribution, and characteristics of wetlands, making it hard to assess the consequences of development interventions. Because of political instability in Sudan and the inaccessible nature of the Sudd, recent measurements of flooding and seasonal dynamics are inadequate. Analyses of multitemporal and multisensor remote sensing datasets are presented in this paper, in order to investigate and characterize flood pulsing within the Sudd wetland over a 12-month period. Wetland area has been mapped along with dominant components of open water and flooded vegetation at five time periods over a single year. The total area of flooding (both rain and river fed) over the 12 months was 41 334 km2, with 9176 km2 of this constituting the permanent wetland. Mean annual total evaporation is shown to be higher and with narrower distribution of values from areas of open water (1718 mm) than from flooded vegetation (1641 mm). Although the exact figures require validation against ground-based measurements, the results highlight the relative differences in inundation patterns and evaporation across the Sudd.

    Full Text Available Sudán ha sufrido varios conflictos en su periferia desde 1955, solo contando con un periodo relativamente pacífico de una década en 1972-1983. Sin embargo, a pesar de sus conflictos regionales el Estado sudanés excluyente ha sobrevivido hasta hoy. Su supervivencia ha sido posible no sólo por las prestaciones económicas que acompañan el reconocimiento internacional, sino también por la intervención externa por parte de otros estados y actores privados. Este artículo pretende explicar cómo se configuró Sudán como una entidad política, y cómo una élite árabe-musulmana ha conseguido construir y mantener el estado excluyente lo suficientemente fuerte como para combatir los desafíos que se presentan desde la periferia. El artículo también señala cómo la relación que ha mantenido el Estado sudanés con actores internacionales le ha permitido sobrevivir a pesar de prolonga dos periodos de conflictos armados regionales.  Sudan has suffered many periphery conflicts since its independence in 1955, enjoying only one relatively pacific decade from 1972 to 1983. In spite of its regional conflicts, however, the Sudanese state has survived till today. This has been possible not only because of the economic assistance that accompanies its international recognition, but also because of the foreign intervention by other states and private actors. This article aims to explain the configuration of Sudan as a political entity, and how an Arab-Muslim elite has managed to build and maintain the marginalizing state strong enough to fight the challenges arising at its periphery. The article also elucidates how the relationship between the Sudanese state and international actors has allowed for its survival in spite of prolonged periods of regional armed struggle.

    Full Text Available Introduction: Unintended or unplanned pregnancy has been a distressing reality among females in the reproductive age group particularly in developing countries. The repercussions of such events range from illegal abortions to various health related problems associated with pregnancy in mothers. The current study aimed to determine the prevalence of unintended pregnancy among married women in an urban and rural community in Khartoum state, to determine the associated factors of unintended pregnancy and to verify the reasons behind unintended pregnancy as perceived by the married women in the area. Methodology: It was a community?based; cross sectional study conducted in Riyadh and Alshekh Elfadni areas in Khartoum state. The sample size was calculated as 341. The study population were married women of reproductive age (15?49 years, selected by multistage stratified sampling. Data was collected by a pre?tested questionnaire and analysed by SPSS software. Chi square test was used to test the association between the dependent and independent variables. Level of significance was determined at 95% (P value < 0.05 was considered as significant. Results: Prevalence of unintended pregnancy was high at 30.2% among the study sample. Significant association (95% CI, p<0.05 was seen between unintended pregnancy and education, household size, parity and use of modern contraceptives methods Conclusion: This study concluded that the prevalence of unintended pregnancy among married women in rural and urban communities in Khartoum state is high. The unintended pregnancy increases as the level of education increases. Women with big household size and high parity are more likely to have experienced unintended pregnancy. The most important reason behind unintended pregnancy is less spacing between one pregnancy and the other.

    An outbreak of a devastating virus disease occurred in common ben (phaseolus vulgaris) in Berber area, the River Nile State, during the 2004/2005 cropping season, with symptoms of stunting and yellowing. The disease incidence reached a level of more than 85% in all visited fields. One hundred fifty symptomatic samples, collected from different fields at Hudeiba, Berber and Shendi were blotted on nitrocellulose membranes and tested for the presence of different viruses, using the tissue blot immunoassay (TBIA) technique. The results of the serological tests revealed that 95% of the samples were positive for cowpea mild mottle virus (CPMMV). Among the common bean genotypes screened for resistance to CPMMV, only RO/2/1 and Giza 3 were resistant to the disease.(Author)

    While many health services strive to be equitable, accessible and inclusive, peoples’ right to health often goes unrealized, particularly among vulnerable groups. The extent to which health policies explicitly seek to achieve such goals sets the policy context in which services are delivered and evaluated. An analytical framework was developed – EquiFrame – to evaluate 1) the extent to which 21 Core Concepts of human rights were addressed in policy documents, and 2) coverage of 12 Vulnerable Groups who might benefit from such policies. Using this framework, analysis of 51 policies across Malawi, Namibia, South Africa and Sudan, confirmed the relevance of all Core Concepts and Vulnerable Groups. Further, our analysis highlighted some very strong policies, serious shortcomings in others as well as country-specific patterns. If social inclusion and human rights do not underpin policy formation, it is unlikely they will be inculcated in service delivery. EquiFrame facilitates policy analysis and benchmarking, and provides a means for evaluating policy revision and development. PMID:22649488

    Full Text Available Severe acute malnutrition and acute systemic infection are often synergistic in children and lead to considerable mortality. The main aim of this research was to determine whether children with severe acute malnutrition can mount an acute phase reactant response measured by C-reactive protein. This was a descriptive, cross-sectional, hospital-based study that was carried out in the five main children hospitals in Khartoum state, from November 1st, 2012 to March 1st, 2013. 132 children with severe acute malnutrition were included in the study. Data collection included history, examination and C-reactive protein measurement. The data were analyzed using Statistical Package for Social Sciences (SPSS for descriptive and inferential statistics. The main results revealed that 93(70.5% children between 12-23 months of age and most of them had marasmus. Diarrhoea was the commonest presenting symptoms in 86.4%, followed by fever and vomiting. Most of the children (82.6% had positive C-reactive protein with variable levels. In conclusion malnourished children are able to synthesize C-reactive protein in response to an infectious process and the magnitude of this response is increased in those with severe infections.

The optimal plan and existing farm situation were changed by 3.3 and 5.6% for gross margin and cash income, respectively. Results of LP also indicated a positive change in production patterns of resource use; 3.3, 6.2, 3.5, 3.3 and 9.1% for land, cash income, labour, seeds supply and productivity, respectively under existing and optimal plan. Partial crop budgeting revealed that, all treatments were financially gave positive returns. Dominance analysis showed that cowpea ainelgazal, okra, roselle and sesame herhri crops were dominated by crops of millet ashana, watermelon, groundnut and guar, respectively. Marginal analysis exposed that, for every SDG 1.00 invested in improved seeds cultivation, farmer can expect to cover the SDG 1.00 and obtain an additional SDG 1.345; then, additional seed rate implies a further marginal rate of SDG 43.9. Sensitivity analysis for cost over run and benefit reduction by 10% indicated highly stability with MRR of 1.22, 3.991 and 1.21 and 3.951% for watermelon and guar, respectively. The productivity of improved seeds compared to local ones was increased in some varieties and decreased among others. This study reached to some recommendations for improving crop productivity, production and livelihood of

    The current socio-economic and political landscape of Sudan and South Sudan can be described as one that is war-ridden and deeply divided by religion, culture, ethnicity and ownership over oil. It has been more than twelve months since the secession of Southern Sudan from the North (See Map 1). Despite the secession, general instability continues. To deal with this turmoil, Sudan declared a so-called “state of emergency” in 2012 along its border with South Sudan. The reason for this was the o...

    The WHO Global Code of Practice on the International Recruitment of Health Personnel (hereafter the WHO Code) was adopted by the World Health Assembly in 2010 as a voluntary instrument to address challenges of health worker migration worldwide. To ascertain its relevance and effectiveness, the implementation of the WHO Code needs to be assessed based on country experience; hence, this case study on Sudan. This qualitative study depended mainly on documentary sources in addition to key informant interviews. Experiences of the authors has informed the analysis. Migration of Sudanese health workers represents a major health system challenge. Over half of Sudanese physicians practice abroad and new trends are showing involvement of other professions and increased feminization. Traditional destinations include Gulf States, especially Saudi Arabia and Libya, as well as the United Kingdom and the Republic of Ireland. Low salaries, poor work environment, and a lack of adequate professional development are the leading push factors. Massive emigration of skilled health workers has jeopardized coverage and quality of healthcare and health professional education. Poor evidence, lack of a national policy, and active recruitment in addition to labour market problems were barriers for effective migration management in Sudan. Response of destination countries in relation to cooperative arrangements with Sudan as a source country has always been suboptimal, demonstrating less attention to solidarity and ethical dimensions. The WHO Code boosted Sudan's efforts to address health worker migration and health workforce development in general. Improving migration evidence, fostering a national dialogue, and promoting bilateral agreements in addition to catalysing health worker retention strategies are some of the benefits accrued. There are, however, limitations in publicity of the WHO Code and its incorporation into national laws and regulatory frameworks for ethical recruitment. The

    A rapid analysis method by coupling carbon nanotube film (CNTF) microextraction with desorption corona beam ionization (DCBI) was developed for the determination of Sudan dyes (I-IV) and Rhodamine B in chilli oil samples. Typically, CNTF was immersed into the diluted solution of chilli oil for extraction, which was then placed directly under the visible plasma beam tip of the DCBI source for desorption and ionization. Under optimized conditions, five dyes were simultaneously determined using this method. Results showed that the analytes were enriched by the CNTF through the π-π interactions, and the proposed method could significantly improve the sensitivities of these compounds, compared to the direct analysis by DCBI-MS/MS. The method with a linear range of 0.08-12.8 μg g(-1) and good linear relationships (R(2) > 0.93) in a multiple reaction monitoring (MRM) mode was developed. Satisfactory reproducibility was achieved. Relative standard deviations (RSDs) were less than 20.0%. The recoveries ranged from 80.0 to 110.0%, and the limits of detection (LODs) were in the range of 1.4-21 ng g(-1). Finally, the feasibility of the method was further exhibited by the determination of five illegal dyes in chilli powder. These results demonstrate that the proposed method consumes less time and solvent than conventional HPLC-based methods and avoids the contamination of chromatographic column and ion source from non-volatile oil. With the help of a 72-well shaker, multiple samples could be treated simultaneously, which ensures high throughput for the entire pretreatment process. In conclusion, it provides a rapid and high-throughput approach for the determination of such illicit additions in chilli products.

    The humanitarian response to the crisis in Darfur is the largest humanitarian operation in the world. To investigate the evolution of the conditions of the affected population, we analysed trends in malnutrition and mortality, the most widely accepted indicators for assessing the degree of severity of a crisis. We did a meta-analysis of 164 publicly available surveys taking into account changes in the contextual situation and humanitarian aid; type of population [residents and internally displaced persons (IDPs)]; and seasonal variations. Data on global acute malnutrition (GAM), severe acute malnutrition (SAM), crude death rate (CDR) and under-five death rate (U5DR) were analysed using a random effect model. GAM and SAM decreased by 16% and 28%, respectively, in 2004-05, whereas CDR dropped by 44-75% per year depending on state and type of population and U5DR decreased by an overall 50% yearly. Both security and the humanitarian contexts became increasingly complex after 2005, but levels of malnutrition stabilized in North and South Darfur. In West Darfur, GAM remained stable but SAM tended to increase for IDPs, although mortality rates remained constant. Mortality increased slightly for residents in South Darfur after 2005, even though nutritional status was stable. GAM, SAM, CDR and U5DR fluctuated markedly with seasons. A meta-analysis of myriads of surveys permitted us to draw an overall picture of the situation in Darfur and to identify some of its influencing factors. The large humanitarian operation, which gained momentum through 2004-05, was able to contain the crisis despite huge difficulties, but did not compensate for seasonal variations. The situation has remained fragile with some negative patterns tending to emerge. It is crucial that the humanitarian situation continues to be closely monitored.

    Full Text Available Aim: The survey was carried out to detect anti- C. burnetii antibodies in goat's sera samples in eight States in the Sudan during September 2010 – July 2011. Materials and Methods: In a preliminary study, four hundred and sixty caprine sera samples collected from eight States in the Sudan were screened for anti- Coxiella burnetii (the causative agent of Q fever antibodies using a commercial indirect ELISA (iELISA kit. Results: The results showed an overall prevalence rate 24.22% of Q fever antibodies. The prevalence rate of antibodies ranged from 6.7% in Kassala to 40% in South Darfur. The prevalence rates were highest in South Darfur (40% and South Kordofan (34.7%, moderate in El Gazira (29.7%, Khartoum (29.1%, the Northern (24% and the River Nile (20.2% States. It was lowest in the White Nile (7.5% and Kassala (6.7% States. Conclusion: It could be concluded that Q fever is prevalent in goats in the Sudan. Therefore, further epizootiological investigations on Q fever in other farm animals and man at the country level is important to monitor and determine the magnitude of Q fever infection in order to estimate its economic impact on animal industry and its public health hazard in the Sudan. In addition, the impact of Q fever among shepherds should be studied. [Vet. World 2012; 5(7.000: 394-397

    The natural radionuclide content of 20 samples collected from Kurun Mountain, western Sudan, has been determined using gamma spectrometry. The data showed that ''2''3 8 U and its decay products were the principal contributors of radioactivity in phosphate deposits. The range of the activity concentration was measured in apatite phosphate rock samples was 378.03-1332.58 Bq/Kg with a mean value of 815.46 Bq/Kg and the data showed that most of samples concentrated in medial comparable with top and bottom of mountain. The distribution of samples indicated that the weathering effect and the rainfall may be the main reasons to enhance the mobility and solubility of uranium from top to bottom of mountain.(Author)

    The mechanisms of the toxicity of Sudan dyes to the key antioxidant enzyme catalase (CAT) were investigated by spectroscopic methods, calorimetry techniques, enzyme activity assay, and molecular docking. Results showed that Sudan dyes bound to CAT through hydrophobic force, which changed the microenvironment of tryptophan and tyrosine residues, leading to a conformational alteration and shrinkage of the protein. Enzyme activity assay and molecular docking revealed that the activity of CAT was slightly inhibited in the presence of Sudan dyes. In comparison, the binding of Sudan II with CAT was slightly stronger than Sudan IV. Also, Sudan II and Sudan IV showed a different impact on the microenvironment of aromatic amino acid residues. But the dyes had very similar effects on conformation and activity of the protein. This work provides an essential reference for the evaluation of Sudan dyes' effects on body's antioxidant defense system and safe use of Sudan dyes. © 2017 Wiley Periodicals, Inc.

    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)

    The impacts of armed conflict on ecosystems are complex and difficult to assess due to restricted access to affected areas making satellite remote sensing a useful tool for studying direct and indirect effects of conflict on the landscape. The Imatong Central Forest Reserve (ICFR) in South Sudan together with the nearby Dongotana Hills and the Agoro-Agu Forest Reserve (AFR) in Northern Uganda share a boundary and encompass a biologically diverse montane ecosystem. This study used satellite data combined with general human population trends to examine the impact of armed conflict and its outcome on similar forest ecosystems both during and after hostilities. A Disturbance Index (DI) was used to investigate the location and extent of forest cover loss and gain in three areas for two key time periods. Results indicate that the rate of forest recovery was significantly higher than the rate of disturbance both during and after wartime in and around the ICFR. In contrast, the nearby Dongotana Hills experienced relatively high rates of disturbance during both periods; however, post war period losses were largely offset by some gains in forest cover. Discussions with local inhabitants confirmed these findings and provided further insights into the underlying causes impacting forest cover and wildlife. South Sudan is the latest nation to join the Global Environment Facility (GEF). While the GEF does not explicitly address conflict, many of the projects it supports occur in conflict and post-conflict zones with wide-ranging repercussions for both people and the environment. In an effort to assess best practices for working in conflict and post-conflict areas, the GEF Scientific and Technical Advisory Panel (STAP) will undertake an analysis of GEF-funded projects over the last two decades to identify where the GEF has promoted cooperation between groups and states, and/or made a positive contribution toward conflict avoidance resulting in shared environmental benefits.

The prevalence was observed to be high in crossbred dams (70% with statistically significant difference (P<0.05 compared to local ecotype (9.3%. However, no correlation was observed between infection rates in two age groups. Conclusion: Neosporosis is prevalent in cattle in most States of Sudan. Absence of evidence of infection in three of the States investigated may reflect the small number of herds and sera tested. [Vet. World 2012; 5(8.000: 465-468

    Full text: Background: Despite relative political stability, humanitarian situation in Warrap State in South Sudan remains fragile as several vulnerable households are facing crisis resulting in acute food insecurity. High levels of food insecurity are concentrated in the areas with increased internally displaced populations. The WFP 2012 annual nutrition and livelihood report indicated that 12% and 27% of IDPs and returnees respectively were severely food insecure. These communities live in areas that are adversely affected by multiple shocks, including border insecurity, excessive seasonal flooding, inflation austerity, and a high influx of returnees which contributed to poor humanitarian indicators. World Vision South Sudan (WVSS) provided emergency nutrition support to the communities in Gogrial West, Gogrial East, Tonj North, Tonj South and Tonj East to reduce severe malnutrition and deaths. The nutrition interventions focused on capacity building on community structure that refers children under-five years with severe acute malnutrition for treatment to community-based outpatient therapeutic treatment (OTP) sites, run by WVSS’s volunteer workers and other NGO partners. Objectives: The purpose of this article is to inform the review of the prevalence of moderate acute malnutrition in communities that faced prolonged crisis Method: review of the baseline and post intervention nutrition survey reports conducted using the ena- for SMART methodology & annual nutrition and livelihood reports. The review covered four areas of operation in Warrap State. Findings: the findings showed the prevailing nutrition status reflects unacceptable thresholds in most of the years where the survey was conducted. The global acute malnutrition situation is to be critical (above 15%) with little change in the levels of moderate acute malnutrition during the course of the years except seasonal variation due to unchanged underlying and root c (Table1 - display omitted).

    2013-11-01

    Human resources for health (HRH) in the Sudan were limited by shortages and the maldistribution of health workers, poor management, service fragmentation, poor retention of health workers in rural areas, and a weak health information system. A "country coordination and facilitation" process was implemented to strengthen the national HRH observatory, provide a coordination platform for key stakeholders, catalyse policy support and HRH planning, harmonize the mobilization of resources, strengthen HRH managerial structures, establish new training institutions and scale up the training of community health workers. The national government of the Sudan sanctioned state-level governance of the health system but many states lacked coherent HRH plans and policies. A paucity of training institutions constrained HRH production and the adequate and equitable deployment of health workers in rural areas. The country coordination and facilitation process prompted the establishment of a robust HRH information system and the development of the technical capacities and tools necessary for data analysis and evidence-based participatory decision-making and action. The success of the country coordination and facilitation process was substantiated by the stakeholders' coordinated support, which was built on solid evidence of the challenges in HRH and shared accountability in the planning and implementation of responses to those challenges. The support led to political commitment and the mobilization of resources for HRH. The leadership that was promoted and the educational institutions that were opened should facilitate the training, deployment and retention of the health workers needed to achieve universal health coverage.

    Tinker, J

    1978-01-01

    Formerly productive areas have become wasteland as the desert advances in the Sudan. To understand how desertification is undermining the very survival of the Sahel, one ecosystem is reviewed in detail here: the gum arabic zone of Kordofan. After cotton, gum arabic is Sudan's largest export, worth from $14-26 million in recent years. In this zone the ecologically balanced cycle of gum gardens, fire, grain crops, and fallow is now breaking down; the 1968-1973 drought having in many areas delivered the final blow. Because of a growing population, the cultivation period is extended, and the soil becomes impoverished. Overgrazing in the fallow period, and the lopping of gum trees for firewood is producing a low return on the gum trees. Without this gum to harvest for cash, farmers must repeatedly replant their subsistence crops until the land becomes useless sand. The Sudanese have recognized the problem earlier than most, and a number of imaginative and practicable pilot projects are already in use: 1) waterpoint management; 2) construction of firebreaks; 3) land threatened by shifting dunes has been enclosed by stockproof fence and afforested with local trees; and 4) shelter belts have been planted around town perimeters where old gum tree stumps have started to sprout and the grass is reseeding itself. Out of these pilot projects, and with the advice of the U.N. Environment Program, the U.N. Development Program, and FAO, the Sudanese have developed a modest $26 million desert encroachment control and rehabilitation program (DECARP).

    North Darfur State has been affected by conflict since 2003 and the government has not been able to provide adequate curative health services to the people. The government has come to rely on Non-Governmental Organizations (NGOs) to provide curative health services. This study was conducted to examine the existing collaboration between government and NGOs in curative health service delivery in North Darfur State, and to identify the challenges that affect their collaboration. Documentary data were collected from government offices and medical organizations. Primary data were obtained through interviews with government and NGOs representatives. The interviews were conducted with (1) expatriates working for international NGOs (N=15) and (2), health professionals and administrators working in the health sector (N= 45). The collaboration between the government and NGOs has been very weak because of security issues and lack of trust. The NGOs collaborate by providing human and financial resources, material and equipment, and communication facilities. The NGOs supply 70% of curative health services, and contribute 52.9% of the health budget in North Darfur State. The NGOs have employed 1 390 health personnel, established 44 health centres and manage and support 83 health facilities across the State. The NGOs have played a positive role in collaborating with the government in North Darfur State in delivering curative health services, while government's role has been negative. The problem that faces the government in future is how health facilities will be run should a peaceful settlement be reached and NGOs leave the region.

  6. The transboundary non-renewable Nubian Aquifer System of Chad, Egypt, Libya and Sudan: classical groundwater questions and parsimonious hydrogeologic analysis and modeling

    Parsimonious groundwater modeling provides insight into hydrogeologic functioning of the Nubian Aquifer System (NAS), the world's largest non-renewable groundwater system (belonging to Chad, Egypt, Libya, and Sudan). Classical groundwater-resource issues exist (magnitude and lateral extent of drawdown near pumping centers) with joint international management questions regarding transboundary drawdown. Much of NAS is thick, containing a large volume of high-quality groundwater, but receives insignificant recharge, so water-resource availability is time-limited. Informative aquifer data are lacking regarding large-scale response, providing only local-scale information near pumps. Proxy data provide primary underpinning for understanding regional response: Holocene water-table decline from the previous pluvial period, after thousands of years, results in current oasis/sabkha locations where the water table still intersects the ground. Depletion is found to be controlled by two regional parameters, hydraulic diffusivity and vertical anisotropy of permeability. Secondary data that provide insight are drawdowns near pumps and isotope-groundwater ages (million-year-old groundwaters in Egypt). The resultant strong simply structured three-dimensional model representation captures the essence of NAS regional groundwater-flow behavior. Model forecasts inform resource management that transboundary drawdown will likely be minimal—a nonissue—whereas drawdown within pumping centers may become excessive, requiring alternative extraction schemes; correspondingly, significant water-table drawdown may occur in pumping centers co-located with oases, causing oasis loss and environmental impacts.

    Sudan I is a carcinogenic and mutagenic azo-compound that has been utilized as a common adulterant in spice and spice blends to impart a desirable red color to foods. A novel biosensor combining molecularly imprinted polymers (MIPs), thin layer chromatography (TLC) and surface enhanced Raman spectroscopy (SERS) could determine Sudan I levels in paprika powder to 1 ppm (or 2 ng/spot). Sudan I spiked paprika extracts (spiking levels: 0, 1, 5, 10, 40, 70 and 100 ppm) were prepared. Sudan I imprinted polymers were synthesized by employing the interaction between Sudan I (template) and methacrylic acid (functional monomer), followed by washing to remove Sudan I leaving the Sudan I-binding sites exposed. MIPs were used as a stationary phase for TLC and could selectively retain Sudan I at the original spot with little interference. A gold colloid SERS substrate could enhance Raman intensity for Sudan I in this MIP-TLC system. Principal component analysis plot and partial least squares regression (R(2)=0.978) models were constructed and a linear regression model (R(2)=0.983) correlated spiking levels (5, 10, 40, 70 and 100 ppm) with the peak intensities (721 cm(-1)) of Sudan I SERS spectra. Both separation (30-40s) and detection (1s or 0.1s) were extremely fast by using both commercial bench-top and custom made portable Raman spectrometers. This biosensor can be applied as a rapid, low-cost and reliable tool for screening Sudan I adulteration in foods. Copyright © 2015 Elsevier B.V. All rights reserved.

    Due to rapid urbanization in Khartoum State, Domestic Solid Waste (DSW) management remains the biggest obsession that recurrently attracts the attention of the concern authorities and stakeholders. As one of the seven localities comprised the state, the Sharg El Neel Locality was chosen to study the DSW management efficiency. The materials and methods employed in collection of data is a package of techniques, one of which was by conducting interviews using structured and unstructured questions mainly directed to appropriate persons i.e., householders and particular government employees directly engaged in DSW management operations. The main findings reached in this study were that local authorities lack the necessary capacities to handle the immense problems of DSW management. Shortages of funds, inadequate number of workers, lack of transport and facilities and weakness of attitudes of respondents found to be among factors hindering the DSW management. Accordingly, proper scheduled and timing, well-trained public health officers and sanitary overseers and strict sustainable program to controlling flies, rodents, cockroach and other disease vectors are essential to properly managing DSW. Otherwise, problems resulting from solid waste generation in the study area will be magnitudized and the surrounding environment will definitely be deteriorated.

    Mass drug administration (MDA) of antibiotics is a key component of the so-called "SAFE" strategy for trachoma control, while MDA of anthelminthics provides the cornerstone for control of a number of other neglected tropical diseases (NTDs). Simultaneous delivery of two or more of these drugs, renowned as "integrated NTD control," is being promoted to reduce costs and expand intervention coverage. A cost analysis was conducted alongside an MDA campaign in a remote trachoma endemic area, to inform budgeting for NTD control in South Sudan. A first round of antibiotic MDA was conducted in the highly trachoma endemic county of Mayom, Unity state, from June to August 2010. A core team of seven staff delivered the intervention, including recruitment and training of 44 supervisors and 542 community drug distributors. Using an ingredients approach, financial and economic costs were captured from the provider perspective in a detailed costing database. Overall, 123,760 individuals were treated for trachoma, resulting in an estimated treatment coverage of 94%. The economic cost per person treated was USD 1.53, excluding the cost of the antibiotic azithromycin. Ninety four per cent of the delivery costs were recurrent costs, with personnel and travel/transport costs taking up the largest share. In a remote setting and for the initial round, MDA of antibiotics was considerably more expensive than USD 0.5 per person treated, an estimate frequently quoted to advocate for integrated NTD control. Drug delivery costs in South Sudan are unlikely to decrease substantially during subsequent MDA rounds, as the major cost drivers were recurrent costs. MDA campaigns for delivery of one or more drugs in South Sudan should thus be budgeted at around USD 1.5 per person treated, at least until further costing data for delivery of other NTD drugs, singly or in combination, are available.

    Full Text Available Bank failures threaten the economic system as a whole. Therefore predicting bank financial failures is crucial to prevent andor lessen its negative effects on the economic system. Financial crises affecting both emerging markets and advanced countries over the centuries have severe economic consequences but they can be hard to prevent and predict identifying financial crises causes remains both science and art said Stijn Claessens assistant director of the International Monetary Fund. While it would be better to mitigate risks financial crises will recur often in waves and better crisis management is therefore important. Analyses of recurrent causes suggest that to prevent crises governments should consider reforms in many underlying areas. That includes developing prudent fiscal and monetary policies better regulating the financial sector including reducing the problem of too-big-to-fail banks and developing effective macro-prudential policies. Despite new regulations and better supervision crises are likely to recur in part because they can reflect deeper problems related to income inequality the political economy and common human behavior. As such improvements in crisis management are also needed. This is originally a classification problem to categorize banks as healthy or non-healthy ones. This study aims to apply Discriminant analysis and Support Vector Machines methods to the bank failure prediction problem in a Sudanese case and to present a comprehensive computational comparison of the classification performances of the techniques tested. Eleven financial and non-financial ratios with six feature groups including capital adequacy asset quality Earning and liquidity CAMELS are selected as predictor variables in the study. Credit risk also been evaluated using logistic analysis to study the effect of Islamic finance modes sectors and payment types used by Sudanese banks with regard to their possibilities of failure.

    Female genital mutilation and cutting (FGM/C, herein FGM) is a widespread and harmful practice. The Government developed a national campaign in Sudan, called Saleema, to change social norms discouraging FGM. Saleema translates to being "whole", healthy in body and mind, unharmed, intact, pristine, and untouched, in a God-given condition. An interim evaluation was conducted using focus groups among Sudanese adults. The primary aim was to explore perceptions of the Saleema poster exemplars and to assess if the desired themes were being communicated. Secondary aims were to understand more about participants' information sources, values, and suggestions for the campaign broadly. The Saleema campaign evaluation included four focus groups from each of the 18 states in Sudan (72 total). Participants were presented with three poster stimuli from the Saleema campaign and asked about the content and their reactions. Themes were coded inductively by concepts that arose through content in the transcripts. Codes were also reviewed in conjunction with themes from the broader Saleema evaluation framework. Participants reported the most common source of information or admiration was from local leaders who are responsive to a community, media-based outlets, and discussions among community members. Participants held high value for education, community solidarity, and/or religious devotion. Participants had positive opinions of Saleema and responded positively to the branding elements in the posters and the campaign as a whole. The most common suggestion was continued awareness. Advocacy, training, and posters were suggested to highlight the harms of FGM through leaders or in community settings. Individuals suggested that these activities target older women and individuals in rural villages. There was also a burgeoning theme of targeting youth for support of the campaign. The results of this focus group analysis demonstrate support for future Saleema campaign efforts promoting

    Recent epidemics of visceral leishmaniasis (VL) in Sudan and South Sudan (locally known as Kala Azar) have caused an estimated 100,000 deaths and have renewed the impetus for defining the ecological boundaries of this vector borne disease. In the past 30 years outbreaks have occurred cyclically within this country, but recent shifts in endemicity have necessitated a more robust understanding of the drivers of the disease. Previous work (e.g. Gebre-Michael et al., 2004; Ashford & Thomson, 1991; Hoogstraal & Heyneman, 1969) has suggested that the primary biological vector in this region, the female sand fly Phlebotomus orientalis, exhibits sensitivities to environmental and climatic variables. Results of this study showed a relationship between precipitation and inundation during months of the transmission season (April-July) and the number of confirmed cases in the following September-January period. Particular months of the transmission season with below-average precipitation were better indicators of lagged reports of VL than others. During VL epidemics (2009, 2010, 2011) the month of June exhibited below average precipitation. The two largest epidemics (2010, 2011) were associated with years of below average precipitation in the month of April. Inundation during April-July (AMJJ) also exhibited a strong inverse relationship with reported VL cases in the following September- January (SONDJ). This relationship was best explored when comparing the VL case data of a specific medical center to the inundation anomalies. Results are typified by the Lankien Medical Center analysis where below average inundation during April displays an inverse relationship with VL cases in the following SONDJ. Drought may lead to below average inundation, which could allow for soils to maintain their fissures, thus maintaining the sand fly breeding habitat, resulting in a sustained breeding season for the sandflies (Quate, 1964). Above-average precipitation and inundation might have the

    It has been 20 years since the introduction of health insurance in Sudan. This study was the first one that explored health insurance services in Sudan from the perspectives of the insurers. This was a qualitative, exploratory, interview study. The sampling frame was the list of Social Health Insurance and Private Health Insurance institutions in Sudan. Participants were selected from the four Social Health Insurance institutions and from five Private Health Insurance companies. The study was conducted in January and February 2017. In-depth individual interviews were conducted with a convenient sample of key executives from the different health insurers. Ideas and themes were identified and analysed using thematic analysis. The result showed that universal coverage was not achieved despite long time presence of Social Health Insurance and Private Health Insurance in Sudan. All participants described their services as comprehensive. All participants have good perception of the quality of the services they provide, although none of them investigated customer satisfaction. The main challenges facing Social Health Insurance are achieving universal coverage, ensuring sustainability and recruitment of the informal sector and self-employed population. Consumers' affordability of the premiums is the main obstacle for Private Health Insurance, while rising healthcare cost due to economic inflation is a challenge facing both Social Health Insurance and Private Health Insurance. In spite of the presence of Social Health Insurance and Private Health Insurance in Sudan, the country is still far from achieving universal coverage. Moreover, the sustainability of health insurance is questionable. The main reasons include low governmental financial resources and lack of affordability by beneficiaries especially for Private Health Insurance. This necessitates finding solutions to improve them or trying other types of health insurance. The quality of services provided by Social

    This article describes a UN HIV/AIDS and sexually transmitted disease (STD) project in war-torn south Sudan. The 3-year project relies on collaboration between adversaries and implementation in government-held and rebel-controlled areas. The project aims to reduce the risk and vulnerability to HIV/AIDS/STDs and to foster dialogue among adversaries as a means of conflict resolution. The World Health Organization will contribute technical assistance. Local partners including the government, the Southern Sudan Independence Movement, and the Sudanese People's Liberation Movement will contribute resources valued at about $100,000. The total UN contribution is about $300,000. HIV transmission has increased due to a high concentration of military personnel and population displacement. Available information suggests that the south has the highest HIV prevalence and 46% of known AIDS cases. STDs increased from 2.3% in 1989 to 14.1% in 1994. The project focuses on women, youth, and other vulnerable groups. The project is in its 9-month preparatory phase. The preparatory phase includes analysis of the HIV/AIDS/STD situation, design of a sustainable program, assessment of causative factors, and establishment of a mechanism for effectively coordinating the project. The civil war will affect priorities, strategies, and activities. In government-controlled areas, the Sudan National AIDS program will conduct activities. In non-government areas, the Sudan Rehabilitation and Relief Association, the Relief Association for South Sudan, and health and humanitarian authorities of the liberation groups will conduct programs. The UN Office of Special Projects will provide oversight during the preparatory phase. Sudan's UN Country Theme Group on HIV/AIDS will be the coordinating group.

    An investigation was carried out on the effect of γ-radiation on the absorption spectra of Sudan red and Sudan blue dyes in organic solutions. A continuous decrease in the absorbance values at the absorption bands was observed with an increase of absorbed dose. The radiation sensitivities of decoloration gave widely different radiation chemical reduction yields (G-values) for the bleaching of both dyes depending on whether xylene, ethyl acetate, or chloroform was used as the solvent. On the basis of experimental results, suggestions are made concerning the dye solutions as prospective dosimeters. The following absorbed dose ranges can be covered: 10 1 -10 2 Gy by 10 -5 M Sudan red or Sudan blue in chloroform; 4 x 10 2 -4 x 10 3 Gy by 10 -5 M Sudan red or Sudan Blue in ethyl acetate; 10 3 -3 x 10 4 Gy by 5 x 10 -6 M Sudan red in xylene.

    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. 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. 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. Toombak use and infection with high risk Human Papilloma Virus (HPV) were extensively investigated and linked to the aetiology of oral cancer in Sudan.

    In this study we estimated the entrance skin doses ESDs for patients undergoing selected diagnostic X -ray examinations in two large public hospitals in Khartoum state, Sudan. The study included the examinations of the chest posterior-anterior (PA) , skull antero-posterior (AP), skull Lateral (LAT) , Lumber spine AP/LAT, abdomen Intravenous urogram (IVU) and Pelvis AP. Totally, 241 patients were included in this study. ESDs were estimated from patients specific exposure parameters using established relation between output (μ Gy/mAs) and tube voltage (kVp). The estimated ESDs ranged from 0.18 - 1.05 mGy for chest PA, 0.98 - 3.48 mGy for Skull (AP), 0.66 - 2.75 mGy for skull (LAT), 1.22 - 4.35 mGy for abdomen (IVU), 1.18 - 5.75 mGy for Pelvis, 1.52 - 5.01 mGy Lumbar spine AP and 2.48 - 10.41 mGy for Lumbar spine (LAT). These values compare well with the international reference dose levels. This study provides additional data that can help the regulatory authority to establish reference dose level for diagnostic radiology in Sudan

    2004-10-01

    The Darfur region of Sudan, composed of three states with a population of approximately six million, has experienced civil conflict during the previous year, resulting in the internal displacement of approximately one million residents and an exodus of an estimated 170,000 persons to neighboring Chad. The conflict has left a vulnerable population with limited access to food, health care, and other basic necessities. In addition, measles vaccination coverage has been adversely affected; in 2003, coverage was reported to be 46%, 57%, and 77% in North, West, and South Darfur, respectively. This report describes measles-control activities in Darfur region conducted by the Federal Ministry of Health (FMOH) in Sudan in collaboration with the United Nations and nongovernmental organizations (NGOs) during March-August 2004. Ongoing measles transmission in camps for internally displaced persons (IDPs) and neighboring communities in Darfur led to a regionwide measles vaccination campaign targeting all children aged 9 months-15 years, resulting in a reduction in reported measles cases. Once security is improved, ongoing efforts to increase measles vaccine coverage will be required to eliminate persistent susceptibility to measles in the Darfur population.

    This study is performed to improve radiation protection level in well logging include tow case studies in Sudan (Lost or misplaced sources). General review of radiation and radiation protection basic concept is highlighted discussed. Also preview of well logging practice and source of radiation use in well logging, safety of radiation sources, storage and manage of not use sources (weak sources) and protection of worker and potential exposure for public and worker, investigations in cause of lost or misplaced sources in well. Assessment was made in well logging using checklist prepared in accordance with the International Atomic Energy Agency IAEA basic safety standard, International Committee for Radiological Protection ICRP and safety in transport of radiation sources. The checklist includes all requirement of radiation protection. It is found that all requirement was present except the delay of calibration of radiation detectors, the movement of radiation sources form storage to base of manipulated area need adequate care for shielding and safe transport and personal monitoring service must be provide in Sudan. Investigation was made in cause of lose of nine radiation source in well it is found that all those sources were loss in different depth in the well and with deferent location and there was no risk because there was no contamination of fluids which caused by damage of loss sources. Some recommendations were stated that, if implemented could improve the status of radiation protection in well logging. (Author)

  16. A review of visceral leishmaniasis during the conflict in South Sudan and the consequences for East African countries.

    2016-08-22

    Visceral leishmaniasis (VL), caused predominantly by Leishmania donovani and transmitted by both Phlebotomus orientalis and Phlebotomus martini, is highly endemic in East Africa where approximately 30 thousands VL cases are reported annually. The largest numbers of cases are found in Sudan - where Phlebotomus orientalis proliferate in Acacia forests especially on Sudan's eastern border with Ethiopia, followed by South Sudan, Ethiopia, Somalia, Kenya and Uganda. Long-standing civil war and unrest is a dominant determinant of VL in East African countries. Here we attempt to identify the correlation between VL epidemics and civil unrest. In this review, literature published between 1955 and 2016 have been gathered from MSF, UNICEF, OCHA, UNHCR, PubMed and Google Scholar to analyse the correlation between conflict and human suffering from VL, which is especially apparent in South Sudan. Waves of forced migration as a consequence of civil wars between 1983 and 2005 have resulted in massive and lethal epidemics in southern Sudan. Following a comprehensive peace agreement, but especially with increased allocation of resources for disease treatment and prevention in 2011, cases of VL declined reaching the lowest levels after South Sudan declared independence. However, in the latest epidemic that began in 2014 after the onset of a civil war in South Sudan, more than 1.5 million displaced refugees have migrated internally to states highly endemic for VL, while 800,000 have fled to neighboring countries. We find a strong relationship between civil unrest and VL epidemics which tend to occur among immunologically naïve migrants entering VL-endemic areas and when Leishmania-infected individuals migrate to new areas and establish additional foci of disease. Further complicating factors in East Africa's VL epidemics include severe lack of access to diagnosis and treatment, HIV/AIDS co-infection, food insecurity and malnutrition. Moreover, cases of post-kala-azar dermal

    This article presents results of measurements for the calibration of radiation protection area monitoring instruments carried out during the period 2006-2008 at Secondary Standard Dosimetry Laboratory of Sudan. The work performed included quality assurance measurements, measurements for the dosimeter calibrations and uncertainty analysis. Calibrations were performed using 137 Cs gamma ray sources produced by OB 85 and OB 34/1 gamma calibrators producing air kerma rate that ranged from 10 μGy/h to 50 mGy/h. Area monitoring instruments were calibrated in terms of ambient dose equivalent, H*(10) derived using air kerma to ambient dose equivalent conversion coefficients. Results are presented for 78 area monitoring instruments representing most commonly used types in Sudan. Radioactive check source measurements for the reference chamber showed deviation within 1% limit. The accuracy in the beam output measurements was within 5% internationally considered as acceptable. The results highlighted the importance of radiation protection calibrations. Regulations are further need to ensure safety aspect really meet the required international standards.

  19. TEACHING THE VIOLENT PAST IN SECONDARY SCHOOLS IN NEWLY INDEPENDENT SOUTH SUDAN

    Directory of Open Access Journals (Sweden)

    Merethe Skårås

    2016-12-01

    Full Text Available This article analyses the teaching and learning of South Sudan history from 1955–2005 in secondary schools in South Sudan with a specific focus on national unity. The article draws on two periods of focused ethnography, from September to December 2014 and July to September 2015, including classroom observation and interviews with teachers, student teachers and students in two geographical locations. Additionally, 69 written essays from secondary school students of History have been analysed in order to get an insight into their knowledge of the recent violent past. The use of classroom video observation makes a significant contribution to the field as most studies focus on documents and textbooks. The analysis focuses on national unity and uses theories of collective memory and attribution to examine the narratives of the past. The article argues that the national narrative of South Sudan is still closely tied to enemy images of the former enemy of Sudan in the north, while internal ethnic tensions are suppressed and excluded from the official national narrative taught in the classroom.

    2017-11-01

    Full Text Available This article explores the complexity of the spatial construction of ethnicity, identity, and sociopolitical interaction among South Sudanese ethnic groups. The article focuses on the interplay between social interaction and the construction of ethnic identity as they affect the notion of human interaction and welfare. The narratives are based on the political sociology of South Sudan after its independence from Sudan and challenges endured in the process of sociopolitical transformation towards the reconstruction of national identity and peaceful coexistence. This discourse gives meaning to visible and invisible ethno-cultural constructions that shaped the norms of social and political interactions among various ethnic groups in the country. The analysis concluded that South Sudan society is socially, politically, and culturally constructed along ethnicized communities with variant perceptions of group and regional identities based on both primordial ties and instrumentalists’ perceptions. These unique characteristics of spaces and construction of social structure has created multi-faceted challenges in the process of social, economic and political reconstruction after the independent of South Sudan in July 2011.

    During the last 5 years of Sudan's decade-long civil war, increased fighting and food shortages in southern Sudan have led to displacement of large numbers of persons. In late 1992, the United Nations (UN), the government of Sudan, and factions of the Sudanese People's Liberation Army negotiated increased access for delivery of relief aid to civilians in southern Sudan. To assist in the targeting of food and other relief aid, CDC and the U.S. Agency for International Development's Office of Foreign Disaster Assistance conducted rapid assessments of nutritional status (children aged Akon (Bahr el Ghazal) (Figure 1).

    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

    Dispersive liquid-phase microextraction with solidification of floating organic drop (SFO-DLPME) is one of the most interesting sample preparation techniques developed in recent years. In this paper, a new, rapid, and efficient SFO-DLPME coupled with high-performance liquid chromatography (HPLC) was established for the extraction and sensitive detection of banned Sudan dyes, namely, Sudan I, Sudan II, Sudan III, and Sudan IV, in foodstuff and water samples. Various factors, such as the type and volume of extractants and dispersants, pH and volume of sample solution, extraction time and temperature, ion strength, and humic acid concentration, were investigated and optimized to achieve optimal extraction of Sudan dyes in one single step. After optimization of extraction conditions using 1-dodecanol as an extractant and ethanol as a dispersant, the developed procedure was applied for extraction of the target Sudan dyes from 2 g of food samples and 10 mL of the spiked water samples. Under the optimized conditions, all Sudan dyes could be easily extracted by the proposed SFO-DLPME method. Limits of detection of the four Sudan dyes obtained were 0.10-0.20 ng g(-1) and 0.03 μg L(-1) when 2 g of foodstuff samples and 10 mL of water samples were adopted, respectively. The inter- and intraday reproducibilities were below 4.8% for analysis of Sudan dyes in foodstuffs. The method was satisfactorily used for the detection of Sudan dyes, and the recoveries of the target for the spiked foodstuff and water samples ranged from 92.6 to 106.6% and from 91.1 to 108.6%, respectively. These results indicated that the proposed method is simple, rapid, sensitive, and suitable for the pre-concentration and detection of the target dyes in foodstuff samples.

    2015-01-01

    Emerging as a sovereign state from decades of civil war, the Republic of South Sudan now faces poverty, a lack of health care infrastructure, a high burden of infectious diseases and a widespread food insecurity. School-aged children and youth, in particular, represent a high-risk demographic for malnutrition and infectious diseases. We screened 109 school-aged children and youth for nutritional status and malaria antigenaemia in Akuak Rak, South Sudan, and found a large proportion of underweight (77/109 = 73%) and prevalent malaria (44/109 = 40%). There was no significant association between malnutrition and malaria. This study represents one of the few published reports on child and youth nutritional status and malaria prevalence in South Sudan since its independence. The implementation of nutrition and malaria screening combined with evidence-based interventions in schools could help target this high burden vulnerable group.

    Beilharz, Traude H; Preiss, Thomas

    2011-01-01

    Nearly all eukaryotic mRNAs terminate in a poly(A) tail that serves important roles in mRNA utilization. In the cytoplasm, the poly(A) tail promotes both mRNA stability and translation, and these functions are frequently regulated through changes in tail length. To identify the scope of poly(A) tail length control in a transcriptome, we developed the polyadenylation state microarray (PASTA) method. It involves the purification of mRNA based on poly(A) tail length using thermal elution from poly(U) sepharose, followed by microarray analysis of the resulting fractions. In this chapter we detail our PASTA approach and describe some methods for bulk and mRNA-specific poly(A) tail length measurements of use to monitor the procedure and independently verify the microarray data.

It focused on cancer patients who were treated by radiation therapy in the period between 2008 and 2009. The study investigator the risk and causative factors and geographical distribution over the sudan states and the relationship of incidence with some patient's customs and dietary habits. 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.

    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)

    Full Text Available Abstract Background Cutaneous Leishmaniasis (CL is endemic in Sudan. It is caused by Leishmania major parasites and transmitted by Phlebotomus papatasi sandflies. Recently, uncommon clinical manifestations of CL have been reported. Moreover, L. donovani parasites that cause Visceral Leishmaniasis (VL have been isolated from CL lesions of some patients who contracted the disease in Khartoum State, Central Sudan with no history of travelling to VL endemic sites on south-eastern Sudan. Because different clinical manifestations and the parasite behaviour could be related to genetic differentiation, or even sub-structuring within sandfly vector populations, a population genetic study was conducted on P. papatasi populations collected from different localities in Khartoum State known for their uncommon CL cases and characterized by contrasting environmental conditions. Methods A set of seven microsatellite loci was used to investigate the population structure of P. papatasi samples collected from different localities in Khartoum State, Central Sudan. Populations from Kassala State, Eastern Sudan and Egypt were also included in the analyses as outgroups. The level of genetic diversity and genetic differentiation among natural populations of P. papatasi was determined using FST statistics and Bayesian assignments. Results Genetic analyses revealed significant genetic differentiation (FST between the Sudanese and the Egyptian populations. Within the Sudanese P. papatasi populations, one population from Gerif West, Khartoum State, exhibited significant genetic differentiation from all other populations including those collected as near as 22 km. Conclusion The significant genetic differentiation of Gerif West P. papatasi population from other Sudanese populations may have important implication for the epidemiology of leishmaniasis in Khartoum State and needs to be further investigated. Primarily, it could be linked to the unique location of Gerif West

    An empirical analysis of the demand for international reserves in the Sudan is presented, based on the error-correction model. This model is parametrically rich enough to allow the division of the effects into long-run influences, short-term adjustments, and proportional equilibrium impacts. Beside addressing conventional issues in reserve demand literature, the model explicitly incorporates the impact on reserve demand of remittances transferred by Sudanese nationals working abroad and the i...

    Use of mobile information technology may aid collection of real-time, standardised data to inform and improve decision-making for polio programming and response. We utilised Android-based smartphones to collect data electronically from more than 8,000 households during a national round of polio immunisation in South Sudan. The results of the household surveys are presented here, together with discussion of the application of mobile information technology for polio campaign planning, implementation and evaluation in a real-time setting. Electronic questionnaires were programmed onto Android-based smartphones for mapping, supervision and survey activities during a national round of polio immunisation. National census data were used to determine the sampling frame for each activity and select the payam (district). Individual supervisors, in consultation with the local district health team, selected villages and households within each payam. Data visualisation tools were utilised for analysis and reporting. Implementation of mobile information technology and local management was feasible during a national round of polio immunisation in South Sudan. Red Cross visits during the polio campaign were equitable according to household wealth index and households who received a Red Cross visit had significantly higher odds of being aware of the polio campaign than those who did not. Nearly 95% of children under five were reported to have received polio immunisation (according to maternal recall) during the immunisation round, which varied by state, county and payam. A total of 11 payams surveyed were identified with less than 90% reported immunisation coverage and the least poor households had significantly higher odds of being vaccinated than the most poor. More than 95% of households were aware of the immunisation round and households had significantly higher odds of being vaccinated if they had prior awareness of the campaign taking place.

    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.

    Full Text Available Heavy seasonal rains cause the River Nile in Sudan to overflow and flood the surroundings areas. The floods destroy houses, crops, roads, and basic infrastructure, resulting in the displacement of people. This study aimed to forecast the River Nile flow at Dongola Station in Sudan using an Artificial Neural Network (ANN as a modeling tool and validated the accuracy of the model against actual flow. The ANN model was formulated to simulate flows at a certain location in the river reach, based on flow at upstream locations. Different procedures were applied to predict flooding by the ANN. Readings from stations along the Blue Nile, White Nile, Main Nile, and River Atbara between 1965 and 2003 were used to predict the likelihood of flooding at Dongola Station. The analysis indicated that the ANN provides a reliable means of detecting the flood hazard in the River Nile.

    Conclusion: Due to an absence of published literature in Sudan, much of the data have been recorded from paper records and empirical observations. Prehospital care and injury prevention in the Sudan is a recent initiative, but it is developing into a promising model with many opportunities for improvement. This momentum should be nurtured and requires a purposive, collective collaboration to draw a blueprint for a locally relevant, effective and efficient prehospital system in Sudan. It is hoped that this article will highlight and encourage further progress.

    Sudan is the largest country in Africa and the Middle East. It has an area of 2. 7 m/sup 2/. This represents more than 8% of the African Continent and almost 2% of the World total area. The country is rejoined into 26 states, 112 Provinces and 614 Localities, constituting the Federal Republic. The geography of Sudan is classified from North to South into desert (34%), semi desert (20%), wood-forest- (35%), agricultural land (7%) and swamps and wetlands (1 %). The population of the country is estimated to be 30.3 million, which is unevenly distributed over the 26 states. The majority of the population is concentrated in 6 states of the central region. About 60% of the population live along the banks of the Nile. Natural disasters and civil conflicts have resulted in high rates of rural-urban migration reaching approximately 15%. Egypt is in the North of Sudan, The Red Sea in the Northeast, Ethiopia and Eritrea in the East, Kenya in the South, Central Africa in the Southwest, Chad in the West border of Sudan and Libya in the Northwest. The climate of Sudan is wholly tropical and rainfall varies with an average less than 75 mm/ annum in the desert and 75-300 mm/annum in semi-desert confined entirely to July and August, to an average of 300-1500 mm/annum in woodland Savannah.

    Full Text Available The plants of genus Cymbopogon are well known for their use in traditional medicine and for their high content of essential oils that are widely used as flavoring agents, fragrances, cosmetics, and pharmaceuticals. Essential oils isolated from the dried stems and inflorescence of cultivated Cymbopogon schoenanthus (L. Spreng. (Poaceae collected from Khartoum state (Sudan in two periods were studied. The results of chemical analysis of C. schoenanthus revealed that this plant is rich in essential oil which is a valuable source of the commercially important monoterpene, piperitone (47.7-71.5%. Other abundant constituents of the oils were intermedeol (6.1-17.3%, δ-2-carene (4.5-10.0% and elemol (2.7-9.0%. The essential oil from the inflorescence was tested for spasmolytic activity using three different experimental models: against spontaneous contractions, contractions induced with acetylcholine and contractions induced with potassium chloride. The oil exhibited strong, significant and dose-dependent spasmolytic activity, indicating the possibility for further investigations of this essential oil for its medicinal purposes or application in food industry.

    The Darfur region of Sudan has been an intense focus of humanitarian concern since rebellions began there early in 2003. In 2004, the US Secretary of State declared that conflict in Darfur represented genocide. Since 2003, many sample surveys and various mortality estimates for Darfur have been made. Nonetheless, confusion and controversy surrounding mortality levels and trends have continued. For this project, results were reviewed from the highest quality field surveys on mortality in Darfur conducted between 2003 and 2008. Trend analysis demonstrated a dramatic decline in mortality over time in Darfur. By 2005, mortality levels had fallen below emergency levels and have continued to decline. Deaths directly due violence have declined as a proportion of all of the deaths in Darfur. Declining mortality in Darfur was not associated with other proximate improvements in well-being, such as improved nutrition. Without large-scale, humanitarian intervention, continuing high rates of mortality due to violence likely would have occurred. If mortality had continued at the high rate documented in 2004, by January 2009, there would have been 330,000 additional deaths. With the humanitarian assistance provided through the United Nations and non-governmental organizations, these people are alive today. A focus on excess deaths among noncombatants may draw attention away from other needs, such as establishing better security, improving service delivery to the displaced, and advocating for internally displaced persons to be reached today and to re-establish their lives and livelihoods tomorrow.

    Results: Positive results were found in 29 (12.8% cattle, 31 (9.8% sheep and 11 (47.8% goat samples. All the studied areas showed positive results. Highest prevalence (66.7% was detected in the sheep and goats in Khartoum, followed by in goats in Nyala (33.3% at western Sudan. Sequence analyses of PIV3 of different regions of Sudan indicated that these were similar in sequence and length. The BLAST analysis indicated that the test sequences were closely related to the available annotated sequences at the GenBank. All these sequences matched with Bovine parainfluenza virus 3 except two those were matching with Swine parainfluenza virus 3. Conclusion: The results prove the existence of PIV3 infection in cattle, sheep and goats in the studied areas in Sudan and suggest its possible role in the respiratory infections. Genetic analysis indicate that the virus is mostly similar with bovine PIV3. [J Adv Vet Anim Res 2016; 3(3.000: 236-241

    Cerebral malaria is considered a leading cause of neuro-disability in sub-Saharan Africa among children and about 25% of survivors have long-term neurological and cognitive deficits or epilepsy. Their development was reported to be associated with protracted seizures, deep and prolonged coma. The study was aimed to determine the discharge pattern and to identify potential and informative predictors of neurological sequelae at discharge, complicating childhood cerebral malaria in central Sudan. A cross-sectional prospective study was carried out during malaria transmission seasons from 2000 to 2004 in Wad Medani, Sinnar and Singa hospitals, central Sudan. Children suspected of having cerebral malaria were examined and diagnosed by a Pediatrician for clinical, laboratory findings and any neurological complications. Univariate and multiple regression model analysis were performed to evaluate the association of clinical and laboratory findings with occurrence of neurological complications using the SPSS. Out of 940 examined children, only 409 were diagnosed with cerebral malaria with a mean age of 6.1 ± 3.3 yr. The mortality rate associated with the study was 14.2% (58) and 18.2% (64) of survivors (351) had neurological sequelae. Abnormal posture, either decerebration or decortication, focal convulsion and coma duration of >48 h were significant predictors for surviving from cerebral malaria with a neurological sequelae in children from central Sudan by Univariate analysis. Multiple logistic regression model fitting these variables, revealed 39.6% sensitivity for prediction of childhood cerebral malaria survivors with neurological sequelae (R² = 0.396; p=0.001). Neurological sequelae are common due to childhood cerebral malaria in central Sudan. Their prediction at admission, clinical presentation and laboratory findings may guide clinical intervention and proper management that may decrease morbidity and improve CM consequences.

    Ebola hemorrhagic fever (EHF) is an emerging threat to public health. The last epidemic in West Africa had a great effect on the affected communities. Timely and effective interventions were necessary in addition to community participation to control the epidemic. The knowledge, attitude and practices of vulnerable communities remain unknown, particularly in Sudan. The aim of this study was to explore the knowledge, attitude and practices of rural residents in Sudan regarding Ebola hemorrhagic fever. We conducted a cross sectional, community-based large-scale study in Al Gaziera state in rural Sudan in eight localities. In total, 1500 random adult participants were selected. The participants were assessed by a predesigned pretested questionnaire regarding their knowledge, attitude and practices regarding Ebola. Their sources of information were determined, and we assessed demographic factors as predictors of knowledge. We found poor knowledge, a fair attitude and suboptimal practices among the participants. The main sources of information were the press and media. Education was the only predictor of knowledge regarding Ebola. A lack of knowledge and suboptimal preventive practices mandates orientation and education programs to raise public awareness. Health care providers are advised to engage more in educating the community. Copyright © 2016 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Summary: We conducted a cross-sectional survey to determine the prevalence of the human immunodeficiency virus (HIV among pregnant women attending a major hospital in Kassala state, eastern Sudan. Unlinked anonymous testing of residual blood specimens, which were originally collected for other routine clinical purposes, was performed using rapid immunochromatographic assays. In total, 430 residual blood specimens were consecutively collected over a 6-week period (April–May 2010. Specimens from the antenatal clinic (ANC constituted 50.7% (218/430 of the total whereas specimens from the labour ward accounted for the remaining 49.3% (212/430. The median age of pregnant women was 29 years (range 16–40. The prevalence of HIV-1 infection was 0.23% (1/430 [95% confidence interval = 0.01–1.29%]. The only reactive specimen came from a 20-year-old ANC attendee. We report low HIV prevalence among pregnant women in eastern Sudan but further research is needed to confirm our findings. An integrated framework to diagnose and treat maternal HIV infection should be developed in order to prevent transmission to infants. Keywords: HIV, Prevalence, Pregnancy, Eastern Sudan

    Agricultural expansion and over-cutting of trees for fuelwood are important causes of deforestation in arid and semi-arid countries such as Sudan. The consequence is increased desertification and high erosion and loss of soil nutrients leading to declining agricultural productivity. However, the social costs of the deforestation externality are not taken into account in present forest management and land use planning in Sudan leading to under-pricing and over-exploitation of the country's forest resources. This study evaluated the suitability of approaches commonly used by most forest resource management agencies for prediction of the state and control of harvesting of forest resources against alternative empirical simulation models using relevant information about economic behaviour of trading agents in the fuelwood market. Results showed the clear superiority of models integrating market behaviour over current approaches in the ability to better simulate real trends of wood consumption and hence depletion rates. The study also adopted an optimal control model to derive socially optimal forest harvesting regimes. The results showed that current rates of forest resource rent recovery and reforestation efforts are very far from optimal. Results also suggest that, in addition to optimal pricing and higher reforestation efforts, promotion and availability of fuel substitutes and investment in wood energy conversion efficiencies have a strong potential for curbing the problem of deforestation in Sudan.

    Sudan dyes in spices are often assumed to arise from cross-contamination or malicious addition. Here, experiments were carried out to identify the potential source of Sudan I-IV in Capsicum fruits through investigation of their contents in native Capsicum tissues, soils and associated agronomic materials. Sudan II-IV was not detected in any of the tested samples. Sudan I was found in almost all samples except for the mulching film. Sudan I concentrations decreased from stems to leaves and then to fruits or roots. Sudan I levels in soils were significantly elevated by vegetation treatment. These results exclude the possibility of soil as the main source for Sudan I contamination in Capsicum fruits. Further study found out pesticide and fertilizer constitutes the major source of Sudan I contamination. This work represents a preliminary step for a detailed Sudan I assessment to support Capsicum management and protection in the studied region. Copyright © 2014 Elsevier Ltd. All rights reserved.

    In 2009, the international Stop Transmission of Polio (STOP) program began supporting the Global Polio Eradication Initiative in the Republic of South Sudan to address shortages of human resources and strengthen acute flaccid paralysis surveillance. Workforce capacity support is provided to the South Sudan Expanded Program on Immunization by STOP volunteers, implementing partners, and non-governmental organizations. In 2013, the Polio Technical Advisory Group recommended that South Sudan transition key technical support from external partners to national staff as part of the Polio Eradication and Endgame Strategic Plan, 2013-2018. To assist in this transition, the South Sudan Expanded Program on Immunization human resources development project was launched in 2015. This 3-year project aims to build national workforce capacity as a legacy of the STOP program by training 56 South Sudanese at national and state levels with the intent that participants would become Ministry of Health staff on their successful completion of the project. © The Author 2017.

    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.

    The red dye Sudan I was investigated by Raman spectroscopy using different excitation wavelengths (1064, 532 and 244 nm). A calculation of the Raman spectrum based on quantum mechanical ab initio density functional theory (DFT) was made using the RB3LYP method with the 3-21G and 6-311+G(d,p) basis...... of the Sudan I molecule was involved in the majority of the vibrations through N N and C–N stretching and various bending modes. Low-intensity bands in the lower wavenumber range (at about 721, 616, 463 and 218 cm−1) were selectively enhanced by the resonance Raman effect when using the 532 nm excitation line....... Comparison was made with other azo dyes in the literature on natural, abundant plant pigments. The results show that there is a possibility in foodstuff analysis to distinguish Sudan I from other dyes by using Raman spectroscopy with more than one laser wavelength for resonance enhancement of the different...

    Full Text Available Cancer treatment is still nascent to non-existent in South Sudan. Basic surgical removal of cancer growths is the only option for many people. The country does not possess an oncology facility and consequently, with no access to chemotherapy and radiotherapy, treatment is a major challenge. Those who can afford it are referred for further management to countries such as the Sudan, Egypt, Uganda, India or South Africa.

    Medical diaspora options, including the engagement of expatriate physicians in development efforts within their home country, are being called for to reverse the effects of brain drain from developing countries. This paper presents the results of a study exploring the potential contributions for the Sudanese Medial Diaspora Options to the healthcare delivery system (HCDS) in Sudan, focusing on the options of temporal and permanent returns and the likely obstacles faced in their implementation. This was a cross-sectional study using a mixed methods design including quantitative and qualitative approaches. For the quantitative approach, the study, which focused on the possible contribution of the diaspora to healthcare delivery in Sudan, was based on an online survey using random purposive and snowballing sampling techniques involving 153 Sudanese physicians working in Saudi Arabia and other Gulf States, the United Kingdom, the Republic of Ireland, and the United States of America. The qualitative approach involved in-depth interviews with returnee physicians and key informants in Sudan, focusing on the return experiences, the barriers for return, and the options to improve future contributions. Despite contributions of the Sudanese medical diaspora being of a small scale considering the size of the phenomenon, as well as infrequent and not appropriately organized, their inputs to academia and the links built with overseas institutions and specialist clinical services were nevertheless remarkable. The main barrier to temporal return was inappropriate organization by the local counterparts, while those for permanent return of physicians were poor work environment, insufficient financial payment, unsecured accommodation, and offspring education. The study identified short-term return as a feasible option considering the country's current conditions. Proper coordination mechanisms for short-term returns and facilitation of permanent return through stakeholders

    Measurements of uranium and thorium isotopes, {sup 226} Ra, {sup 210} Po, {sup 228} Ra, {sup 40} K and fallout radionuclide {sup 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 {alpha} spectrometry. The external exposure due to {gamma} 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 {mu}Sv/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.

    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.

  18. Sudan: the human price of oil

    International Nuclear Information System (INIS)

    2000-01-01

    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 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 The recent case of the arrest, prosecution and imprisonment of Mariam Yahya Ibrahim Ishag of Sudan has drawn attention to the place of Islamic sharia law in contemporary, diverse and multireligious communities and nation states. Islamic sharia law was used to charge Mariam of apostasy; she was subsequently sentenced to 100 lashes followed by hanging. Religious extremism and one of its resultant effects, namely persecution, particularly of women and other minorities, is a persistent hindrance to ongoing efforts against poverty responses. Religious extremism goes against the spirit of Article 18 of the Universal Declaration of Human Rights and Article 18 of the International Covenant of Civil and Political Rights, of which many nation states are signatories. The Catholic vows of consecration � poverty, chastity and obedience � are very helpful perspectives that can assist in pursuing responses to religious extremism and the resultant intolerance, persecution and dispossession.Intradisciplinary and/or interdisciplinary implications: Drawing from the Roman Catholic Church�s vows of consecration, the article argues for a stance that communities can take in situations that call for solidarity with people in vulnerable situations.

    Full Text Available The objective of this study is to analyze and compare tannins of three common Acacia species of Sudan, since vegetable tannins are important in leather industry. Acacia nilotica and Acacia seyal samples were collected from Sunt Forest in Khartoum State, while Acacia senegal samples were collected from the Debabat Forest in South Kordofan State. Bark samples from bulk collections of the three Acacia species were extracted with boiled deionized water. The amount of tannins present in these bulk samples was determined by Folin-Denis method for total phenolic materials, followed by precipitation with hide-powder. The difference between the amount of phenolic materials present before and after addition of hide-powder represents the amount of tannins present. The percentage of tannins in the leaves, bark, and mature and immature fruits of collections of individuals of Acacia species was estimated; mature and immature fruits of Acacia nilotica contain tannins (22.15% and 22.10%, resp.. The leaves of Acacia nilotica and Acacia seyal contain tannins (11.80% and 6.30%, resp..

    Drought is a natural hazard characterized by an abnormally dry event in the hydrological cycle caused by insufficient precipitation over an extended period of time, which affects more people than any other natural disaster and results in social, economic and environmental costs. In Africa, the economic system is based primarily on natural resources for example farming. For this reason, climate variability and events such as drought are phenomena that can represent significant disturbances and threats in the agricultural systems. In particular, this study concerns the monitoring of environmental changes in the south sector of South Sudan. The climate and environment in the South Sudan have shown localised changes during the course of this century and recurrent wars and droughts in the last years determined a large food-crisis. Actually, the security situation is stabilised with sporadic fighting concentrated in Jonglei, Unity and Upper Nile States. With the stabilisation of the conflict, many refugees have returned to their regions, trying to recover the economic structure based mainly on agriculture. For this reason, it is important to monitoring and analysis the vegetation and drought trend over the last years to support agricultural development and food security, in particular in post-conflict areas. This study focuses on the analysis of the relationship between the temporal variations of state of vegetation and the precipitation patterns. A historical analysis of the vegetation behaviour (NDVI) and the drought during the year is developed. In addition, with the aim to identify the wet and dry seasons, an analysis of precipitation is performed. Based on the vegetation and precipitation trends obtained, it is possible to characterize the best areas to start an agricultural system, giving priority to certain areas in order to plan the land use for agricultural purposes and programming crop (which and where). Consequently, with the aim to identify possible

    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)

    Graphical abstract: Display Omitted -- Highlights: •A well-dispersed AuNPs/RGO nanocomposite was fabricated via a green and in situ reduction method. •This nanocomposite displays excellent electro-catalysis activity for the oxidation of Sudan I. •The AuNPs/RGO/GCE exhibits superior comprehensive properties for the detection of Sudan I. •This proposed method was successfully applied to detect Sudan I in chilli powder and ketchup sauce. -- Abstract: In this paper, we are presenting a facile, green and in situ synthesis strategy for the convenient preparation of well-dispersed gold nanoparticles (AuNPs)-decorated reduced graphene oxide (RGO) without the use of any template molecules and poisonous reductant. The as-synthesized nanocomposite has been detailedly characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray powder diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis as well as electrochemical technologies. The morphological and structural characterizations illustrate that AuNPs can be efficiently decorated on RGO with the Au content of 20.33 wt% in the matrix and the size of the embedded AuNPs vary between 25 and 40 nm. The electrochemical investigations confirm that the small-sized AuNPs on the RGO film can remarkably boost the electrocatalytic activity for the oxidation of Sudan I, which can be used as an enhanced electrochemical sensing platform for the sensitively detection of the toxicant Sudan I. Moreover, the kinetic parameter studies demonstrate that the Sudan I electro-oxidation at the AuNPs/RGO electrode is a diffusion-controlled process which involves two-electron and two-proton transfer. Under the optimal conditions, a wide linear range of Sudan I detection from 0.01 to 70 μmol L −1 with good linearity (R 2 = 0.9965, 0.9942) and a low detection limit (1.0 nmol L −1 , S/N = 3) were obtained.

    A method development for the determination of an aromatic amine degraded from an azo dye in cloths was carried out. Sodium dithionite was used to cleave the azo bond of Sudan I into its aromatic amines, and the amines, mainly aniline were analyzed using high performance liquid chromatography (HPLC) with UV detection. The efficiency of the reduction process of Sudan I, based on the degree of decolorisation of dye, was measured using the spectrophotometer. The optimized values of the reduction process was found effective when 1:1 ratio of 0.30 % sodium dithionite to Sudan I (dit/ Sud) was used at pH 8. The recovery percentage and relative standard deviation (R.S.D.) of this method was found to be 62.9 - 88.4 % and 7.6 - 21.5 %, respectively. The proposed method was tested on self-dyed cloth samples with Sudan I. Aniline released from the reduction of Sudan I was detected in the self-dyed cloth samples. The results of this study demonstrate the applicability of sodium dithionite for the reduction of the azo dye in the cloth samples. (author)

    Four wheat (Triticum aestivum L.) cultivars, namely condor, El-Nellene, Wadi El Neil and Debeira were characterized on biochemical and molecular bases. The biochemical ones were protein-banding patterns, using sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and isozymes to identify the biochemical genetic fingerprint of the four cultivars. Water-soluble protein-banding pattern showed no polymorphisms among the tested cultivars. The data from starch gel electrophoresis of enzymes, malate dehydrogenase (MDH), esterase (EST) and acid phosphate (ACPH) showed that the cultivars are monomorphic. Further trials to identify the molecular genetic fingerprints of the studied cultivars were carried out using RAPD-PCR twenty-five primers were tested to perform. RAPD-PCR analysis. From the PCR products, a phylogenetic map, i.e, dendrogram, was constructed for the studied cultivars which depicted tow groups. The first group contained Wadi El Neil and Deberia with 48.4% similarity, and the second group contained Condor and El Neileen with 100% similarity. There was no similarity between Condor and Debeira (100% dissimilarity). Therefor, these data can be used subsequently for genetic engineering research and for wheat breeding programmes in the Sudan.(Author)

    This community-based research explores community perspectives on human rights barriers that women encounter in a postconflict setting of southern Sudan. An ethnographic design was used to guide data collection in five focus groups with community members and during in-depth interviews with nine key informants. A constant comparison method of data analysis was used. Atlas.ti data management software facilitated the inductive coding and sorting of data. Participants identified three formal and one set of informal community structures for human rights. Human rights barriers included shifting legal frameworks, doubt about human rights, weak government infrastructure, and poverty. The evolving government infrastructure cannot currently provide adequate human rights protection, especially for women. The nature of living in poverty without development opportunities includes human rights abuses. Good governance, protection, and human development opportunities were emphasized as priority human rights concerns. Human rights framework could serve as a powerful integrator of health and development work with community-based organizations. Results help nurses understand the intersection between health and human rights as well as approaches to advancing rights in a culturally attuned manner.

    Basic questions regarding families of coherent states include describing some constructions of such and the way they can be applied to operator theory or partial differential equations. In both questions, pseudodifferential analysis is important. Recent developments indicate that they can contribute to methods in arithmetic, especially modular form theory. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Coherent states: mathematical and physical aspects’.

    Sorghum-Sudan grass hybrid containing high hydrocyanic acid content can cause hydrocyanic acid poisoning to the livestock and limit the popularization of this forage crop. Molecular markers associated with low hydrocyanic acid content can speed up the process of identification of genotypes with low hydrocyanic acid content. In the present study, 11 polymorphic SSR primers were screened and used for bulked segregant analysis and single marker analysis. Three SSR markers Xtxp7230, Xtxp7375 and Bnlg667960 associated with low hydrocyanic acid content were rapidly identified by BSA. In single marker analysis, six markers Xtxp7230, Xtxp7375, Bnlg667960, Xtxp67-11, Xtxp295-7 and Xtxp12-9 were linked to low hydrocyanic acid content, which explained the proportion of phenotypic variation from 7.6 % to 41.2 %. The markers identified by BSA were also verified by single marker analysis. The three SSR marker bands were then cloned and sequenced for sequence homology analysis in NCBI. It is the first report on the development of molecular markers associated with low hydrocyanic acid content in sorghum- Sudan grass hybrid. These markers will be useful for genetic improvement of low hydrocyanic acid sorghum-Sudan grass hybrid by marker-assisted breeding.

    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 T{sub 4}, T{sub 3}, 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 {mu}g/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 2.70{mu}g/d1 in Kosti town 46.40 {mu}g/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

  20. The Domestic Origins of Sudan's External Debt Crisis

    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.

    The economic, social, ecological and environmental roles and benefits of forests are obvious and need no emphasis. Inefficient use of fuel wood is considered one of the important causes of deforestation. Use of more efficient improved cookstoves is proposed as one of the measures that can reduce demand for fuel wood and charcoal and help in lowering the annoying deforestation rate in many developing countries. During the 1980s and 1990s several programs aiming at testing and disseminating energy saving technologies were implemented in Sudan. One of these technologies was improved cookstoves, which was intended to increase the efficiency of using energy from biomass sources. This study is carried out to examine the adoption rate and the factors affecting adoption of improved cookstoves in Khartoum State. The study is based on primary data collected through personal interviews with husbands and wives in 300 randomly selected households. Regression analysis was used to analyze the data. The results showed that the device's adoption rate was very low. The improved cookstove's relative advantage, housewife's exposure to messages about improved cookstoves, educational level of the housewife and the average educational level of the female household's members had significant positive effect on the household's innovativeness regarding adoption of improved cookstove. Wife's age and the educational level of the husband had negative significant effects. In the Sudanese patriarchal society all the household domestic tasks, particularly food preparation and related activities, are considered women's responsibilities and all the decisions related to them are taken by women. Therefore, these results could be understood as a reflection of the division of labor, gender relations and decision-making process in the Sudanese household.

    In 1996, an epidemic outbreak of visceral leishmaniasis (VL) started in Barbar el Fugara, a village in Gedarif State (eastern Sudan). From 1997 to 2000, regular epidemiological studies were carried out in the human population, as well as in mammals and sand flies. In symptomatic patients, 46/69 lymph node, 6/20 post kala-azar dermal leishmaniasis (PKDL) and 1/4 cutaneous cultures in NNN medium were positive. In 69 dogs, 23/79 lymph node cultures were positive. In other mammals (47 rodents, five donkeys, one mongoose and one monkey) spleen and/or blood cultures were negative. Characterization of isolated strains (by starch gel electrophoresis and isoelectrofocusing) identified three zymodemes of Leishmania donovani, two of L. infantum and two of L. archibaldi complexes from patient samples and three zymodemes of L. donovani, three of L. infantum and two of L. archibaldi complexes from dog samples. Five of them were present in both man and dog. For the first time, a strain from a PKDL case was identified as L. infantum, and a child had the same L. infantum zymodeme in VL and in subsequent PKDL. Blood samples from dogs were studied by immunofluorescent antibody test (IFAT). The seroprevalence in dogs was 72.5%, 74.3% and 42.9% in 1998, 1999 and 2000, respectively. By using CDC miniature light traps 12 745 sand flies were collected and then identified. Phlebotomus papatasi (7%) and P. orientalis (5%) were sympatric, mainly inside homes (85% and 75%, respectively). These results, the relative stability of seroprevalence in dogs and the intradomiciliar presence of P. orientalis, known as a vector of VL in Sudan, suggest several hypotheses: (i) man is responsible for the disease in dogs, (ii) the dog is the reservoir of VL, (iii) the dog is an intermediate host between a possible sylvatic cycle and the anthroponotic cycle. More extensive studies are needed to assess the transmission cycle of VL in this area of Sudan.

    A novel, simple, fast, and miniaturized method, termed in-line micro-matrix solid-phase dispersion (in-line MMSPD), coupled with high performance liquid chromatography (HPLC) was developed for the simultaneous extraction and determination of Sudan dyes (i.e. Sudan I-IV, Sudan orange G, Sudan black B, and Sudan red G) with the aid of an experimental design strategy. In this method, a matrix solid-phase dispersion (MSPD) column including a suitable mixture of polar sorbents was inserted in the mobile phase pathway, and while the interfering compounds were retained, the analytes were eluted and entered into the analytical column. In this way, the extraction, elution, and separation of the analytes were performed sequentially. Under the optimal experimental conditions (including the amount of sample, 0.0426g; amount of dispersant phase, 0.0216g of florisil, 0.0227g of silica, 0.0141g of alumina; and blending time, 112s), the limits of detection (LODs), limits of quantification, linear dynamic ranges, and recoveries were obtained to be 0.3-15.3μgkg(-1), 1-50μgkg(-1), 50-28,000μgkg(-1), and 94.5-99.1%, respectively. The results obtained showed that determination of the selected Sudan dyes in food samples using an enough sensitive and a simple analytically validated method like in-line MMSPD may offer a suitable screening method, which could be useful for food analysis and adulteration.

  4. The Historical and religious conditions of the split of Sudan ... in the context of Christian-Muslim relationships

    Directory of Open Access Journals (Sweden)

    Waldemar Cisło

    2014-04-01

    Full Text Available The split into the predominantly Muslim Northern Sudan, and Southern Sudan with a Christian and animist majority, had been emerging in the course of many centuries. Without any doubt, one is bound to mention the natural and geographical boundaries, the ethnical diversity of the regions, the influence exercised during the centuries by the Egyptians, Arabs and later on by the British. According to the opinions of some experts on the subject, there can be two distinct matters that have contributed to the split of the North and the South. These were education and religion. Apart from education, also the issue of religion was dividing the Sudan. After the declaration of independence on January 1, 1954 all the Christian private schools in the South were closed down. There remained only state schools with Arabic as the language of instruction and with the upbringing model based on the Koran teaching. Having obtained political independence, the fears of the British administration and Christian missionaries became a reality: Islam was made the state religion. The only way to attain an occupational and social status was to convert to Islam. Frequently, this took place according to the rule of an already accomplished fact or by pressure. In the context of Sudan, one of the biggest country in Africa, with its population of over 37 million, made up of 70 per cent Muslim believers , 14 per cent of Christians, and 12 per cent of animists, it is of great importance for the perception of fundamentalism to be familiar with the history of this country.

    This study assessed willingness to pay for National Health Insurance Fund (NHIF) among public servants in Juba City. NHIF is the proposed health insurance scheme for South Sudan and aims at achieving universal health coverage for the entire nation's population. One compounding issue is that over the years, governments' spending on healthcare has been decreasing from 8.4% of national budget in 2007 to only 2.2% in 2012. A cross-sectional study design using contingent evaluation was employed; data on willingness to pay was collected from 381 randomly selected respondents and 13 purposively selected key informants working for the national, state and Juba County in September 2015. Qualitative data were analysed using conceptual content analysis. T-tests and linear regressions were performed to determine association between WTP for NHIF and independent variables. Up to 381 public servants were interviewed, of which 68% indicated willingness to pay varying percentages of total monthly individual income for NHIF. Over two-thirds (67.8%) of those willing to pay could pay up to 5% of their total monthly income, 22.9% could pay up to 10% and the rest could pay 25%. Over 80% were willing to pay up to 50 SSP (1 USD = 10 SSP) premiums for medical consultation, laboratory services and drugs. The main factors influencing the respondents' decisions were awareness, alternative sources of income, household size, insurance cover and religion. Willingness to pay is mainly influenced by awareness, alternative sources of individual income, household size, insurance cover and religion. Most of the public servants were aware of and willing to pay for NHIF and prefer a premium of up to 5% of total monthly income. There is need to create awareness and reach out to those who do not know about the scheme in addition to a detailed analysis of other stakeholders. Consideration could be made by the Government of South Sudan to start the scheme at the earliest opportunity since the majority of

    Full Text Available A cross sectional survey was carried out in dairy farms in four States of Sudan to determine prevalence of reproductive health disorders that affect dairy cattle industries in the country. A total of 575 adult female cows in dairy farms located in Khartoum, Gezira, Sennar, and White Nile States were investigated using questionnaire survey and face-to-face interviews with the owners. The results indicated that 24.4% of the animals were affected with one or more reproductive health disorders. Abortion (57.1% represented the major health problem affecting calf yield, followed by infertility (34.3% and neonatal death (8.6%. Other health problems included stillbirth, vaginitis and retained placenta, anomalies, metritis and repeat breeder. Most of the abortion cases were detected during third trimester (76.25% followed by first (12.5% and second (11.25% trimesters. Finally, countrywide investigations of reproductive disorders and increasing awareness to the owners are recommended for designing successful control strategies of reproductive disorders in Sudan.

    Full Text Available The aim of this study was to determine the health hazards acquired by the residents nearby Soba sewage treatment plant. A descriptive cross-sectional study was carried out in Soba locality, Khartoum, Sudan. An interviewer-administrated questionnaire was assigned to 462 residents of the area living in four geographically distributed squares around the sewage plant. The data was analyzed in SPSS; Cronbach’s alpha reliability scale of measurement was used to check the internal validity of six variables related to the quality of life. A logistic regression analysis was used to assess the relationship between the health hazards and the quality of life. Among the 462 residents, difficulty in breathing (37.9% and nausea (37.2 were the principal health hazards. Moreover, the residents had a satisfactory level of awareness (88.7% about the health hazards. The utmost impact on the quality of life was psychological (97.2%. It was statistically correlated with the reported factors, which impacted the quality of life in the district as revealed by the Cronbach’s alpha reliability test with absenteeism (P=0.026, disability (P=0.014, socialization (P=0.032 and death (P=0.016. A logistic regression analysis revealed chemical hazards had a statistically significant association (P<0.05 with quality of life of the residents of Soba district. The study strongly entails the fact that sewage treatment plants crave exceptional consideration from the concerned responsible authorities, together with the fact that the evolved health threats should be confronted with immense responsibility as soon as possible.

  15. Sources of Sahelian-Sudan moisture: Insights from a moisture-tracing atmospheric model

    The summer rainfall across Sahelian-Sudan is one of the main sources of water for agriculture, human, and animal needs. However, the rainfall is characterized by large interannual variability, which has attracted extensive scientific efforts to understand it. This study attempts to identify the source regions that contribute to the Sahelian-Sudan moisture budget during July through September. We have used an atmospheric general circulation model with an embedded moisture-tracing module (Community Atmosphere Model version 3), forced by observed (1979-2013) sea-surface temperatures. The result suggests that about 40% of the moisture comes with the moisture flow associated with the seasonal migration of the Intertropical Convergence Zone (ITCZ) and originates from Guinea Coast, central Africa, and the Western Sahel. The Mediterranean Sea, Arabian Peninsula, and South Indian Ocean regions account for 10.2%, 8.1%, and 6.4%, respectively. Local evaporation and the rest of the globe supply the region with 20.3% and 13.2%, respectively. We also compared the result from this study to a previous analysis that used the Lagrangian model FLEXPART forced by ERA-Interim. The two approaches differ when comparing individual regions, but are in better agreement when neighboring regions of similar atmospheric flow features are grouped together. Interannual variability with the rainfall over the region is highly correlated with contributions from regions that are associated with the ITCZ movement, which is in turn linked to the Atlantic Multidecadal Oscillation. Our result is expected to provide insights for the effort on seasonal forecasting of the rainy season over Sahelian Sudan.

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)

    This paper extends in two directions the results of prior work on generalized linear covariance analysis of both batch least-squares and sequential estimators. The first is an improved treatment of process noise in the batch, or epoch state, estimator with an epoch time that may be later than some or all of the measurements in the batch. The second is to account for process noise in specifying the gains in the epoch state estimator. We establish the conditions under which the latter estimator is equivalent to the Kalman filter.

    International Nuclear Information System (INIS)

    Osman, M.Y.

    2008-01-01

    Regulation of the use of ionizing radiation started formally in 1971 when an act has been issued by which the ministry of health was entitled to establish a Radiation Protection Technical Committee (RPTC) as a regulatory body. However, this act didn't come into effect because of the lack of regulations needed to execute the regulatory functions stated in that law. In 1972 the Sudan Atomic Energy Commission (SAEC) act was issued by which the commission was designated as a promoter for the use of nuclear technology. This law was later replaced by the 1996 act by which the Sudan Atomic Energy Corporation (SAEC) was established within the ministry of higher education and latter within the Ministry of Science and Technology (MOST). The board of the corporation established a technical committee (Radiation Protection Technical Committee (RPTC)) to carry out the regulatory functions assigned to the board by the act. The 1996 act didn't repeal the 1971 act; as a result, the two conflicting and overlapping acts are still valid. In 2003 the 1996 act was cancelled and to be replaced by an Order of Establishment within a general law for corporations in the Sudan. In spite of all these mess in providing a proper legislative framework, the RPTC (MOST) managed to secure a fair control of the use of radiation in different applications within the country. In this report, the current status of regulating the use of ionizing radiation as well as major challenges is described

    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.

    2008-01-01

    Radiation doses to patients from some common paediatric X-ray examinations were studied in three hospitals in Khartoum state (Sudan)). Entrance surface dose (ESD) was determined from exposure settings using DosCal software. Totally, 459 patients were included in this study. Mean ESDs obtained from anteroposterior projection for chest, skull, abdomen and pelvis for neonates falls in the range of 52-100, 115-169, 145-183, 204-242 μGy, respectively. For a 1-y-old infant, mean ESD range was 80-114, 153-202, 204-209, 181-264 μGy, respectively. Some doses for neonates and infants were exceeding the reference doses by >20%. The results highlighted that a good technique has to adhere to guidelines necessarily. As demonstrated elsewhere, patients' doses were high in departments using single-phase generators compared with those using constant potential. The results presented will serve as a baseline data needed for deriving reference doses for paediatric X-ray examinations in Sudan. (authors)

    Protozoa are eukaryotic cells distributed worldwide in nature and are receiving increasing attention as reservoirs and potential vectors for the transmission of pathogenic bacteria. In the environment, on the other hand, many genera of the protozoa are human and animal pathogens. Only limited information is available on these organisms in developing countries and so far no information on their presence is available from Sudan. It is necessary to establish a molecular identification of species of the protozoa from drinking and environmental water. 600 water samples were collected from five states (Gadarif, Khartoum, Kordofan, Juba, and Wad Madani) in Sudan and analysed by polymerase chain reaction (PCR) and sequencing. 57 out of 600 water samples were PCR positive for protozoa. 38 out of the 57 positive samples were identified by sequencing to contain 66 protozoa species including 19 (28.8%) amoebae, 17 (25.7%) Apicomplexa, 25 (37.9%) ciliates, and 5 (7.6%) flagellates. This study utilized molecular methods identified species belonging to all phyla of protozoa and presented a fast and accurate molecular detection and identification of pathogenic as well as free-living protozoa in water uncovering hazards facing public health.

    Enteric fever has persistence of great impact in Sudanese public health especially during rainy season when the causative agent Salmonella enterica serovar Typhi possesses pan endemic patterns in most regions of Sudan - Khartoum. The present study aims to assess the recent state of antibiotics susceptibility of Salmonella Typhi with special concern to multidrug resistance strains and predict the emergence of new resistant patterns and outbreaks. Salmonella Typhi strains were isolated and identified according to the guidelines of the International Standardization Organization and the World Health Organization. The antibiotics susceptibilities were tested using the recommendations of the Clinical Laboratories Standards Institute. Predictions of emerging resistant bacteria patterns and outbreaks in Sudan were done using logistic regression, forecasting linear equations and in silico simulations models. A total of 124 antibiotics resistant Salmonella Typhi strains categorized in 12 average groups were isolated, different patterns of resistance statistically calculated by (y = ax - b). Minimum bactericidal concentration's predication of resistance was given the exponential trend (y = n e x ) and the predictive coefficient R 2  > 0 current antimicrobial drug resistance patterns of community-acquired agents causing outbreaks.

    2002-01-01

    The responses of calotropis procera and cassia senna to soil ph, Ca, Mg, K, Na, Mn, Fe, NH 4 -N and P were investigated in three sites in central Sudan, namely Omdurman, Wadelmajzob (Wad Medani) and Kosti. The investigation was carried out by chemical analysis of soil and pant samples collected randomly from 25 sampling points at each site. The data of the soil chemical analysis were analysed using the principal component analysis (PCA). The PCA reflected some what low range of variation in the distribution of the soil nutrient within each of the three investigated sites. Chemical analysis of C. procera and C. senna plants, collected from three investigated sites, showed that they have different levels of nutrients uptake. Although C. senna tends to have low mineral requirements compared with C. procera. it was completely absent from Kosti sit. This may be due to the acidity and high Mn levels at this site.(Author)

    Full Text Available Abstract Background Pregnant women are more susceptible to malaria, which is associated with serious adverse effects on pregnancy. The presentation of malaria during pregnancy varies according to the level of transmission in the area. Our study aimed to demonstrate the prevalence and risk factors for malaria (age, parity and gestational age among pregnant women of eastern Sudan, which is characterized by unstable malaria transmission. Methods The prevalence and possible risk factors for Plasmodium falciparum malaria were investigated in 744 pregnant Sudanese women attending the antenatal clinic of New Haifa Teaching Hospital, eastern Sudan, during October 2003-April 2004. Results A total 102 (13.7% had P. falciparum malaria, 18(17.6% of these were severe cases (jaundice and severe anaemia. Univariate and multivariate analysis showed that, age and parity were not associated with malaria. Women who attended the antenatal clinic in the third trimester were at highest risk for malaria (OR = 1.58, 95% CI = 1.02–2.4; P Women with malaria had significantly lower mean haemoglobin (9.4 g/dl, 95% CI 9.1–9.7 versus 10.7, CI 10.6–10.8, P Conclusion The results suggest that P. falciparum malaria is common in pregnant women attending antenatal care and that anaemia is an important complication. Preventive measures (chemoprophylaxis and insecticide-treated bednets may be beneficial in this area for all women irrespective of age or parity.

    Schistosomiasis and soil-transmitted helminthiasis (STHs) are target neglected tropical diseases (NTDs) of preventive chemotherapy, but the control and elimination of these diseases have been impeded due to resource constraints. Few reports have described study protocol to draw on when conducting a nationwide survey. We present a detailed methodological description of the integrated mapping of schistosomiasis and STHs on the basis of our experiences, hoping that this protocol can be applied to future surveys in similar settings. In addition to determining the ecological zones requiring mass drug administration interventions, we aim to provide precise estimates of the prevalence of these diseases. A school-based cross-sectional design will be applied for the nationwide survey across Sudan. The survey is designed to cover all districts in every state. We have divided each district into 3 different ecological zones depending on proximity to bodies of water. We will employ a probability-proportional-to-size sampling method for schools and systematic sampling for student selection to provide adequate data regarding the prevalence for schistosomiasis and STHs in Sudan at the state level. A total of 108,660 students will be selected from 1811 schools across Sudan. After the survey is completed, 391 ecological zones will be mapped out. To carry out the survey, 655 staff members were recruited. The feces and urine samples are microscopically examined by the Kato-Katz method and the sediment smears for helminth eggs respectively. For quality control, a minimum of 10% of the slides will be rechecked by the federal supervisors in each state and also 5% of the smears are validated again within one day by independent supervisors. This nationwide mapping is expected to generate important epidemiological information and indicators about schistosomiasis and STHs that will be useful for monitoring and evaluating the control program. The mapping data will also be used for overviewing

    From 2006 to 2012, the South Sudan Guinea Worm Eradication Program reduced new Guinea worm disease (dracunculiasis) cases by over 90%, despite substantial programmatic challenges. Program logistics have played a key role in program achievements to date. The program uses disease surveillance and program performance data and integrated technical-logistical staffing to maintain flexible and effective logistical support for active community-based surveillance and intervention delivery in thousands of remote communities. Lessons learned from logistical design and management can resonate across similar complex surveillance and public health intervention delivery programs, such as mass drug administration for the control of neglected tropical diseases and other disease eradication programs. Logistical challenges in various public health scenarios and the pivotal contribution of logistics to Guinea worm case reductions in South Sudan underscore the need for additional inquiry into the role of logistics in public health programming in low-income countries.

    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.

    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)

    The timely collection and analysis of all safeguards relevant information is the key to drawing and maintaining soundly-based safeguards conclusions. In this regard, the IAEA has made multidisciplinary State Evaluation Groups (SEGs) central to this process. To date, SEGs have been established for all States and tasked with developing State-level approaches (including the identification of technical objectives), drafting annual implementation plans specifying the field and headquarters activities necessary to meet technical objectives, updating the State evaluation on an ongoing basis to incorporate new information, preparing an annual evaluation summary, and recommending a safeguards conclusion to IAEA senior management. To accomplish these tasks, SEGs need to be staffed with relevant expertise and empowered with tools that allow for collaborative access to, and analysis of, disparate information sets. To ensure SEGs have the requisite expertise, members are drawn from across the Department of Safeguards based on their knowledge of relevant data sets (e.g., nuclear material accountancy, material balance evaluation, environmental sampling, satellite imagery, open source information, etc.) or their relevant technical (e.g., fuel cycle) expertise. SEG members also require access to all available safeguards relevant data on the State. To facilitate this, the IAEA is also developing a common, secure platform where all safeguards information can be electronically stored and made available for analysis (an electronic State file). The structure of this SharePoint-based system supports IAEA information collection processes, enables collaborative analysis by SEGs, and provides for management insight and review. In addition to this common platform, the Agency is developing, deploying, and/or testing sophisticated data analysis tools that can synthesize information from diverse information sources, analyze diverse datasets from multiple viewpoints (e.g., temporal, geospatial

    In the present work radioactivity in building materials (granite) central Sudan was evaluated. In general the building materials used in Sudan are derived either from rocks or soil. These contain trace amounts of naturally occurring radioactive materials(NORMs), so it contains radionuclides from uranium and thorium series and natural potassium. The levels of these radionuclides vary according to the geology of their site of origin. High levels increase the risk of radiation exposure in homes(especially exposure due to radon). Investigation of radioactivity in granite used of the building materials in Sudan is carried out, a total of 18 major samples of granite have been collected and measured using X- ray fluorescence system (30 mci). The activity concentrations have been determined for uranium ("2"3"8U), thorium ('2"3"2Th) and potassium("4"0K) in each sample. The concentrations of uranium have been found to range from 14.81 Bq/kg to 24.572 Bq/kg, thorium between 10.02 Bq/kg and 10.020-84.79 Bq/kg and the potassium concentration varies between 13.33 Bq/kg to 82.13 Bq/kg. Limits of radioactivity in the granite are based on dose criteria for controls. This study can be used as a reference for more extensive studies of the same subject in future. (Author)

    This study was designed to update the existing information concening goiter prevalence and iodine deficiency disorders in omdurman city and to compare the effects of thyroxine versus iodine in the treament of simlpe goiter. Thyroxine in different doses is commonly used in treatment of simple goiter in Sudan. The goiter survey was conducted in Omdurman secondary school for girls (Khartoum state). Of the goitrous subjects 99 girls were selected to participate in the treament protocol. A control group of 54 non-goitrous subjects from the same school were also included. The goitrous subjects were divided randomly into two groups receiving either daily dose of 100 μg thyroxine for six months or a single dose of 400 mg of oral iodine in the form of iodized oil. Blood and urine samples were collected from the goitrous and control group and recollected from the goitrous subjects every six weeks for six months. Goiter size was assessed at 3,6 and 14 months after the commencement of the treament. Blood samples were analyzed for serum level of T4,T3 and TSH using sensitive radioimmunoassay techniques. Urine samples were analyzed for urinary iodine excretion. Goiter was found in 139 students out of 1034, (13.4%). They were all euthyroid with simple diffuse goiter.T4 in the goitrous group (93.3±26.9 nmole /L (mean±SD)) was significanty lower than in the control group (106.4±18.2nmole/L,p<0.05).

    1980-02-01

    An analytical theory has been developed which allows one to calculate the occurrence probability of the top event of a fault tree with multistate (two or more than two states) components. It is shown that, in order to correctly describe a system with multistate components, a special type of boolean algebra is required. This is called 'boolean algebra with restrictions on variables' and its basic rules are the same as those of the traditional boolean algebra with some additional restrictions on the variables. These restrictions are extensively discussed in the paper. It is also shown that the boolean algebra with restrictions on variables facilitates the task of formally combining fault tree analysis with state analysis. The computer program MUSTAFA 1 based on the above theory has been developed. It can analyse fault trees of system containing statistically independent as well as dependent components with two or more than two states. MUSTAFA 1 can handle coherent as well as non coherent boolean functions. (orig.) 891 HP/orig. 892 MB [de

    Full Text Available South Sudan is one of the most endemic countries for visceral leishmaniasis (VL, and is frequently affected by large epidemics. In resource-limited settings, clinicians require a simple clinical tool to identify VL patients who are at increased risk of dying, and who need specialised treatment with liposomal amphotericin B and other supportive care. The aim of this study was to develop and validate a clinical severity scoring system based on risk factors for death in VL patients in South Sudan.A retrospective analysis was conducted of data from a cohort of 6,633 VL patients who were treated in the Médecins Sans Frontières (MSF hospital in Lankien between July 2013 and June 2015. Risk factors for death during treatment were identified using multivariable logistic regression models, and the regression coefficients were used to develop a severity scoring system. Sensitivity and specificity of score cut-offs were assessed by receiver operating characteristic (ROC analysis.In multivariable models, risk factors for death in adult VL patients were: anaemia (odds ratio (OR 4.46 (95% CI 1.58-12.6 for Hb <6g/dL compared with ≥9g/dL, nutritional status (OR 4.84 (2.09-11.2 for BMI <13 kg/m2 compared with ≥16 kg/m2, weakness (OR 4.20 (1.82-9.73 for collapsed compared with normal weakness, jaundice (OR 3.41 (1.17-9.95, and oedema/ascites (OR 4.86 (1.67-14.1. For children and adolescents the risk factors were: age (OR 10.7 (6.3-18.3 for age <2 years compared with 6-18 years, anaemia (OR 7.76 (4.15-14.5 for Hb <6g/dL compared with ≥9g/dL, weakness (OR 3.13 (22.8-105.2 for collapsed compared with normal weakness, and jaundice (OR 12.8 (4.06-40.2. Severity scoring predictive ability was 74.4% in adults and 83.4% in children and adolescents.Our evidenced-based severity scoring system demonstrated sufficient predictive ability to be operationalised as a clinical tool for rational allocation of treatment to VL patients at MSF centres in South Sudan.

    This study monitors some trace elements concentration in street and industrial dust from Wad Medani city, Gezira State in central Sudan. A total of 20 samples of dust were collected from crowded and non-crowded streets, material processing workshop and a tannery. Samples were treated by sequential chemical extraction in five fractions, which termed as exchangeable fraction, carbonate fraction, Fe-Mn oxides fraction, organic matter fraction and residual fraction. The same samples were digested by wet method. The obtained solutions were analyzed for Cr, Fe, Ni, Cu, Zn, and Pb content using Atomic Absorption Spectrometer (AAS) and for Na and K content using Flame Emission Spectrometer (FES). X-Ray Fluorescence Spectrometer (XRF) was used to determine the total content of Na, K, Cr, Fe, Ni, Cu, Zn and Pb in the bulk sample. Results of total content, which obtained by AAS, FES and XRF spectrometry, were compared with each other and with total content for the fractionated samples. Certified reference materials from IAEA were analyzed to make sure of the data obtained. The ranges of concentrations obtained are 113-3900 μg/g for Cr, 0.3-110.4 mg/g for Fe, 27-500 μg/g for Ni, 34.7-4390 μ/g for Cu, 62-1320 μg/g for Zn and 40-1250 μg/g for Pb dry weight. The obtained results were analyzed statistically using multivariate methods that include Correlation Matrices, Principal Component Analysis (PCA) and cluster analysis. The concentrations of trace elements in street and industrial dust of Wad Medani were compared with those values in literature. It has been observed that the dust from street and industrial area of wad Medani is slightly affected by anthropogenic sources.(Author)

    To investigate the epidemiology of sickle cell disease (SCD) and determinants of knowledge, attitudes and practices (KAP) towards SCD in western Kordofan State, Sudan. A community-based, descriptive, cross-sectional study was conducted in three towns. Three hundred and seventy-two households were polled, and blood samples for haemoglobin phenotyping were collected from 1116 individuals. Sociodemographic, socio-economic and KAP data were collected using investigator-administered questionnaires. Descriptive, frequency distribution and multiple regression analyses were performed. About 50.9% of the study population were Misseriya tribes. Consanguineous marriages were reported by 67.5% of the households. The highest percentage of homozygous SCD was 2.8% among children under 5 years of age. About 24.9% were carriers of HbS allele (HbAS). HbS allele frequency was highest in children aged 5-11 years (18.3%, CI: 13.7-22.9%) and lowest in males >15 years old (12.0%, CI: 6.1-17.9%). The average HbS frequency across all age groups was 14.5% (95% CI: 12.2-16.8%). The most frequent β-globin gene cluster haplotype was the Cameroon (30.8%), followed by the Benin (21.8%), the Senegal (12.8%) and the Bantu (2.2%) haplotypes. About 17.0% of all-cause child deaths were due to SCD. The estimated change in log odds of having the SS genotype per year increase in age was (-) 0.0058 (95% CI -0.0359, 0.0242). This represents a non-statistically significant 2.9% increase in 5-year mortality for individuals with the SS genotype relative to those with AS and AA genotypes. About 46.9% of the households had poor knowledge, 26.1% had satisfactory knowledge, and 26.9% had good knowledge about sickle cell disease. Mothers' and fathers' educational levels were significant predictors of good knowledge about SCD (P < 0.05). About 48.0% had a satisfactory attitude towards sickle cell disease while 30.7% had poor attitude and only 21.3 showed good attitudes. Poor knowledge about SCD and low socio

    Full Text Available The majority of those living in the border region of Kenya, Sudan, and Uganda are pastoralists, whose livelihoods are dictated by the upkeep and size of their herds. Harsh environmental conditions force pastoralists to migrate in search of water and pasturelands during the dry season. With limited access to water and competing rights to land, intertribal conflict arises when pastoralists from one tribe enter the territory of another. The increased availability of small arms in the region from past wars increasingly makes ordinary clashes fatal. Governments in the region have responded with heavy-handed coercive disarmament operations. These have led to distrust and subsequent violent clashes between communities and security providers. This report reviews the scale, consequences of, and responses to the many pastoral conflicts, utilizing methodological tools such as key informant interviews, retrospective analysis, and a thorough review of available literature.

    El-Fadni Suliman, Issameldin

    This thesis explores language policies, language conflict and language-user attitudes toward arabicization which refers to the use of Arabic as a medium of instruction in teaching medicine in universities in the Sudan. It follows up these objectives: (1) To highlight the roots of arabicization and implemented language planning activities through document analysis. (2) To report on the advantages and disadvantages of both Arabic and English as media of instruction in teaching medicine in the Sudan. (3) To survey the attitudes of students and their instructors in the colleges of Khartoum, Omdurman and Gezira universities towards arabicization using two similar developed questionnaires and an interview for faculty members. The questionnaires were distributed to the students and faculty members in the three colleges to probe six factors: (I) The extent of use of languages of instruction (2) Readiness of the students to receive medical studies in English (3) The difficulties they face (4) English as a medium of instruction in medical colleges (5) Arabic as a medium of instruction in medical colleges (6) Students' preference of a language of instruction. The study utilized tables, charts and chi square tests to illustrate the attitudes of students and their faculty members. The study has revealed that the attitude of most of the students and their faculty members were in favor of arabicization in principle. In fact, students showed support for the pedagogical benefits of Arabic like they can prepare and study in Arabic in less time than English. They can take more notes in Arabic than in English. The study has highlighted that Arabic as a native language of the students offers them a mighty and indispensable support for the ability to convey ideas, capacity for imaginative or creative thinking than the limited capacity given by the foreign language. Notwithstanding, English is reported to be very important for students' current medical studies and future career. The

    In the field of inertial confinement fusion (ICF), numerical simulation plays a very important role reproducing real results with a good accuracy. Once considered the needed simplificative approximations, it is obtained and equation system that has to be solved in a more or less complex way. Anyway these simulation codes have to fit the behaviour of real materials with the help of some flexible parameters. In the case of fluid dynamics, the key to fit the equation system to the real material behaviour are the equations of state (EOS) involved in the problem. This is why there is an actual need of using accurate data in order to obtain results that match the real behaviour of materials. Nowadays there are several available sources of real EOS data. These sources are based either in theoretical models fixed with experimental results or in analytical approximations to those models. In this article a comparative analysis is made between two of the most used EOS data sources in simulations. The aim of this work is to check the quality of these data that is commonly used and on which the accuracy of the results depend. (Author) 3 refs

    Echinococcus granulosus (EG) complex, the cause of cystic echinococcosis (CE), infects humans and several other animal species worldwide and hence the disease is of public health importance. Ten genetic variants, or genotypes designated as (G1-G10), are distributed worldwide based on genetic diversity. The objective of this study was to provide some sequence data and phylogeny of EG isolates recovered from the Sudanese one-humped camel (Camelus dromedaries). Fifty samples of hydatid cysts were collected from the one- humped camels (Camelus dromedaries) at Taboul slaughter house, central Sudan. DNAs were extracted from protoscolices and/or associated germinal layers of hydatid cysts using a commercial kit. The mitochondrial NADH dehydrogenase subunit 1 (NADH1) gene and the cytochrome C oxidase subunit 1 (cox1) gene were used as targets for polymerase chain reaction (PCR) amplification. The PCR products were purified and partial sequences were generated. Sequences were further examined by sequence analysis and subsequent phylogeny to compare these sequences to those from known strains of EG circulating globally. The identity of the PCR products were confirmed as NADH1 and cox1 nucleotide sequences using the Basic Local Alignment Search Tool (BLAST) of NCBI (National Center for Biotechnology Information, Bethesda, MD). The phylogenetic analysis showed that 98% (n = 49) of the isolates clustered with Echinococcus canadensis genotype 6 (G6), whereas only one isolate (2%) clustered with Echinococcus ortleppi (G5). This investigation expands on the existing sequence data generated from EG isolates recovered from camel in the Sudan. The circulation of the cattle genotype (G5) in the one-humped camel is reported here for the first time.

  18. The monogenetic Bayuda Volcanic Field, Sudan - New insights into geology and volcanic morphology

    The small monogenetic Bayuda Volcanic Field (BVF; 480 km2), comprising at least 53 cinder cones and 15 maar volcanoes in the Bayuda desert of northern Sudan is one of a few barely studied volcanic occurrences of Quaternary age in Sudan. The exact age of the BVF and the duration of volcanic activity has not yet been determined. Furthermore, not much is known about the eruptional mechanisms and the related magmatic and tectonic processes that led to the formation of the volcanic field. In the framework of a larger project focusing on these points it is the purpose of this contribution to provide a first account of the general geology of the BVF volcanoes as well as a first description of a general stratigraphy, including a first description of their morphological characteristics. This was done by means of fieldwork, including detailed rock descriptions, as well as the analysis of satellite images (SRTM dataset at 30 m spatial resolution). The BVF cinder cones are dominated by scoracious lapilli tephra units, emplaced mainly by pyroclastic fallout from Strombolian eruptions. Many cones are breached and are associated with lava flows. The subordinate phreatomagmatism represented by maar volcanoes suggests the presence of ground and/or shallow surface water during some of the eruptions. The deposits constituting the rims around the maar volcanoes are interpreted as having mostly formed due to pyroclastic surges. Many of the tephra rings around the maars are underlain by thick older lava flows. These are inferred to be the horizons where rising magma interacted with groundwater. The existence of phreatomagmatic deposits may point to a time of eruptive activity during a phase with wetter conditions and therefore higher groundwater levels than those encountered historically. This is supported by field observations as well as the morphological analysis, providing evidence for relatively high degrees of alteration of the BVF volcanoes and therefore older eruption ages as

    Objective: This study was aimed to assess oral cancer awareness among a selected Sudanese population and to evaluate their knowledge and treatment seeking behavior. Methods: A questionnaire- based survey was performed on the general population who attended the oral cancer awareness campaigns carried between 2015 and 2016 in different geographic areas of the Sudan. It was focusing on general awareness of oral cancer, oral cancer risk factors, oral cancer clinical signs/symptoms and treatment seeking behavior. Data were entered by Microsoft excel 2007 and analyzed by SPSS (version 20) using chi square test with P value oral cancer and the media was the common source of information (75.7%). Of all participants only 45.3% mentioned that they don’t have enough knowledge on oral cancer. Some participants believe that oral cancer is treatable (66.5%) whilst 30.4% respond by I don’t know. More than 80% of the respondents were aware that smokeless tobacco (toombak) is a risk factor for oral cancer. While 60.1% were aware of alcohol as a risk factor and 66.2% were aware of smoking as a risk factor. When qui square test was done, smokers were found to be the least to seek help in comparison to non-smokers. The same result was obtained from alcohol consumers but it was different in snuff dippers, as the latter response was similar to that of the non-snuff dippers. Conclusion: This study revealed a level of around 66.6% of oral cancer awareness in different states of Sudan. Counseling sessions should be conducted when necessary with further investigations to find out the reasons behind the continued practice of high risk habits, despite knowledge.

    Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral zoonotic disease caused by Crimean-Congo hemorrhagic fever virus (CCHFV), a member of the genus Nairovirus in the family Bunyaviridae. CCHF is typically asymptomatic in animals but can be highly fatal in humans approaching case fatality rate of approximately 30%. In the present investigation, a cross sectional study was conducted to determine the prevalence of CCHF and to identify the potential risk factors associated with CCHFV seropositivity among the one-humped camel (Camelus dromedaries) in Central Sudan. A total of 361 camels selected randomly from six localities were employed in the study. Sera sampled were tested for the presence of CCHFV-specific immunoglobulin G (IgG) antibodies using enzyme-linked immunosorbent assay (ELISA). CCHFV seropositivity was recorded in 77 out of 361 animals accounting for a prevalence rate of 21.3%. Age (OR = 3.6, CI = 1.72-7.79, p-value = 0.026); locality (OR = 5.85, CI = 1.81-18.83, p- value = 0.003), tick number (OR = 4.6, CI = 1.37-9.81, P-value 0.04); tick control (OR = 2.2, CI, 1.11-4.35, P-value = 0.023) and breed (OR = 6.60, CI = 2.38-18.36, P-value = 0.001) were recorded as potential risk factors for contracting CCHF. The prevalence of CCHF is significantly high among camels in Khartoum State, Sudan. Age, breed, locality and tick control are considered as potential risk factors for contracting CCHF. This study would be expected to reduce the impact on the livelihood of pastoral communities and ultimately avoid disease spread in human.

    Full Text Available Abstract Background Enteric fever has persistence of great impact in Sudanese public health especially during rainy season when the causative agent Salmonella enterica serovar Typhi possesses pan endemic patterns in most regions of Sudan - Khartoum. Objectives The present study aims to assess the recent state of antibiotics susceptibility of Salmonella Typhi with special concern to multidrug resistance strains and predict the emergence of new resistant patterns and outbreaks. Methods Salmonella Typhi strains were isolated and identified according to the guidelines of the International Standardization Organization and the World Health Organization. The antibiotics susceptibilities were tested using the recommendations of the Clinical Laboratories Standards Institute. Predictions of emerging resistant bacteria patterns and outbreaks in Sudan were done using logistic regression, forecasting linear equations and in silico simulations models. Results A total of 124 antibiotics resistant Salmonella Typhi strains categorized in 12 average groups were isolated, different patterns of resistance statistically calculated by (y = ax − b. Minimum bactericidal concentration’s predication of resistance was given the exponential trend (y = n ex and the predictive coefficient R2 > 0 < 1 are approximately alike. It was assumed that resistant bacteria occurred with a constant rate of antibiotic doses during the whole experimental period. Thus, the number of sensitive bacteria decreases at the same rate as resistant occur following term to the modified predictive model which solved computationally. Conclusion This study assesses the prediction of multi-drug resistance among S. Typhi isolates by applying low cost materials and simple statistical methods suitable for the most frequently used antibiotics as typhoid empirical therapy. Therefore, bacterial surveillance systems should be implemented to present data on the aetiology and current

    Full Text Available Background: In South Sudan, women disproportionately bear the burden of morbidity and mortality related to sexual and reproductive health, with a maternal mortality ratio of 789 deaths per 100,000 live births. Design: A qualitative study was conducted to analyze how gendered social relations among the Fertit people affect women's ability to exercise control over their reproductive lives and thereby their sexual and reproductive health. Transcripts of 5 focus group discussions and 44 semi-structured interviews conducted with purposefully selected community members and health personnel were analyzed using Connell's relational theory of gender. Results: Women across all age groups report that they have little choice but to meet the childbearing demands of husbands and their families. Women, both young and old, and also elders, are frustrated about how men and society are letting them down and how they are left to bear the reproductive burden. The poverty and chronic insecurity in South Sudan mean that many men have few sources of pride and achievement; conformity and complicity with the hegemonic practices accord both security and a sense of belonging and privilege to men, often at the expense of women's reproductive health. Conclusions: Inequalities in the domestic, social, and economic spheres intersect to create social situations wherein Fertit women's agency in the reproductive realm is constrained. In South Sudan, as long as economic and social opportunities for women remain restricted, and as long as insecurity and uncertainty remain, many women will have little choice but to resort to having many children to safeguard their fragile present and future. Unless structural measures are taken to address these inequalities, there is a risk of both a widening of existing health inequalities and the emergence of new inequalities.

    In the last couple of decades there has been an impressive increase in applications of radioactive material. Such an extensive and widely spread usage of radioactive materials demands safe transportation of radioactive material from the production site to the application location, as well as quick and effective response in a case of an unexpected transportation event according to Sudan Atomic Energy Commission (SAEC) regulation. The thesis described the local practice for transport of radioactive material as compared to the international standards for radiation protection, and also discussed the emergency procedures that must be follow in case of accident during transport of radioactive material. Furthermore, the objective of this study was also to set proposals for how to cope in the event of a radiological accident. The study methods included survey of current literature on safe transport of radioactive material, survey of national regulations on the subjects in additional to case studies aimed at investigating the practical issues pertinent to transport of radioactive materials in Sudan. A comprehensive review was presented on how to classification of radioactive packages and general requirement for all packaging and packages according to international standard. transport of number of radioactive sources from Khartoum airport to the field was evaluated with regard transport index, category of source, type of package, dose rate around the source, time to destination and means of transport of doses to public, worker are be made. All results were within the limit specified in the national as well as international regulation. The study has addressed for the first time the practice of transport of radioactive material in Sudan. It is anticipated that the results will encourage national organizational and professional bodies to enhance radiation protection and safety of radioactive sources. (Author)

    Diabetes mellitus accounts for 11% of total health expenditure worldwide, and most people with diabetes live in low- and middle-income countries. The present study examined the economic and social effects attributed to diabetes in Sudan by calculating out-of-pocket medical expenses and the health and social effects of the disease for people with diabetes (n = 375) and their families compared with a non-diabetic control group (n = 375), matched for age, sex, and residence area. Data were obtained in 2013 in four states within the Sudan, via structured interviews, using instruments from the International Diabetes Federation. Descriptive statistics were used to analyze differences between case and control participants. The median total annual medical expenditure was fourfold higher for people with than without diabetes (US$579 vs US$148, respectively). Annual mean expenditure was 85% higher for those with diabetes (US$1004 vs US$544). People with diabetes were also significantly more likely to suffer from serious comorbidities, such as cardiovascular disorders and foot ulcers, compared with control participants. Moreover, those with diabetes reported a higher proportion of personal adverse social effects, such as being prevented from doing paid work or participating in education, both for themselves and their families. The high economic burden and adverse social effects on people with diabetes and their families in Sudan call for the development of evidence-based policy and program strategies for the prevention and management of diabetes, with an emphasis on low-resource communities. © 2017 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    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

    We report that the intensity of the blue fluorescence of copper nanoclusters coated with polyethyleneimine (PEI) is strongly reduced in the presence of the food dyestuffs Sudan I-IV. This finding was exploited in a label-free fluorescence assay for these Sudan dyes both in ethanol and aqueous solutions. The PEI-capped nanoclusters have an average diameter of 1.8 nm and are displaying, under 355 nm excitation, a blue emission at 480 nm that matches the absorption bands of the Sudan dyes. The clusters are stable in solution for at least 1 month. Under optimum conditions, this assay can be applied to the quantification of the dyes Sudan I, II, III, and IV, respectively, in the 0.1−30, 0.1–30, 0.1–25, and 0.1–25 μM concentration ranges, and the detection limits (3σ/slope) are 65, 70, 45, and 50 nM, respectively. The capability of reducing the fluorescence of the PEI-capped copper nanoclusters is directly related to the number of the functional groups in that Sudan III and IV give lower detection limits. This analytical scheme exhibits a remarkably high selectivity for the Sudan dyes over potentially interfering substances. The method was successfully applied to determine Sudan I, II, III, and IV in hot chilli powder. (author)

    Full Text Available Sudan grass (Sorghum sudanense is an annual warm-season gramineous forage grass that is widely used as pasture, hay, and silage. However, drought stress severely impacts its yield, and there is limited information about the mechanisms of drought tolerance in Sudan grass. In this study, we used next-generation sequencing to identify differentially expressed genes (DEGs in the Sudan grass variety Wulate No.1, and we developed simple sequence repeat (SSR markers associated with drought stress. From 852,543,826 raw reads, nearly 816,854,366 clean reads were identified and used for analysis. A total of 80,686 unigenes were obtained via de novo assembly of the clean reads including 45,065 unigenes (55.9% that were identified as coding sequences (CDSs. According to Gene Ontology analysis, 31,444 unigenes were annotated, 11,778 unigenes were identified to 25 categories in the clusters of orthologous groups of proteins (KOG classification, and 11,223 unigenes were assigned to 280 Kyoto Encyclopedia of Genes and Genomes (KEGG pathways. Additionally, there were 2,329 DEGs under a short-term of 25% polyethylene glycol (PEG treatment, while 5,101 DEGs were identified under the long-term of 25% PEG treatment. DEGs were enriched in pathways of carbon fixation in photosynthetic organisms and plant hormone signal transduction which played a leading role in short-term of drought stress. However, DEGs were mainly enriched in pathway of plant hormone signal transduction that played an important role under long-term of drought stress. To increase accuracy, we excluded all the DEGs of all controls, specifically, five DEGs that were associated with high PEG concentrations were found through RNA-Seq. All five genes were up-regulated under drought stress, but the functions of the genes remain unclear. In addition, we identified 17,548 SSRs obtained from 80,686 unigenes. The newly identified drought tolerance DEGs will contribute to transgenic breeding efforts, while

  16. The question of women and environment in the Sudan: inquiries into eco-feminism and feminist environmentalism.

    Nageeb, S A

    1994-12-01

    This article discusses a theoretical framework suggested by Agarwal on eco-feminism in the context of Sudan and the Kordofam region of Sudan. The paper focuses specifically on one aspect of eco-feminism that is discussed by Shiva (1988). Eco-feminism is the link between the domination and suppression of women and the domination and exploitation of nature. Women are identified with nature, while men are closer to culture, which places women in an inferior position. Because of the link of women with nature, women have a vested interest in restructuring the domination of nature. Feminism and environmentalism both reflect egalitarian and nonhierarchical systems. This analysis tests whether women are the central actors of environment and whether women's and environmental interests can be advanced simultaneously. The Indian experience reflects the class and gender process that results in loss of knowledge and livelihoods among poor rural women. The impact is related to the interaction between ideology and political and economic power. Grass-roots resistance to environmental degradation is strong, and women are engaged due to threats to survival. Sudanese women's role, position, status, and relation to the environment is shaped by the patriarchal order, class, ethnicity, and the sexual division of labor. The Shiva concepts apply to Sudan and the Kordofan region. The marginalization of traditional farming and pastoralism has pushed the growing population into marginal environmental zones. The focus on cash-oriented development, political instability, and insufficient and corrupt bureaucracies have aggravated the environmental crisis. Social inequality has increased. Shiva's theories do not fit Sudanese society and Agarwal's perspective is too general. Some Sudanese women have accumulated wealth, commercial interests, and exploited land.

    Full Text Available Objectives. To assess participants’ knowledge about HIV/AIDS and to identify the factors associated with HIV/AIDS in Sudan. Methods. Observational cross-sectional study carried out at Omdurman National Voluntary Counseling and Testing Centre, Sudan covered 870 participants. Sociodemographic data as well as information related to sexual behavior were collected. Results. Most of the respondents were knowledgeable about the true transmission modes for AIDS virus. Very few respondents knew someone infected with AIDS (4.5%, died of AIDS (8.1%, accepted to live with someone infected with AIDS (4.7% or to work with someone infected with AIDS (2.1%. Regarding sexual behavior, 96.5% had reported their first sexual experience between 20 and 30 years, with 85.7% reporting one or two partners, and only 1.8% reported using condom. Multivariate logistic regression showed that circumcision, religion, marital status, age at first sex, number of sexual partners, education level, and misconception of knowledge are the main risk factors associated with HIV/AIDS. Conclusion. Our results showed that a number of diversity risk factors were associated with HIV/AIDS. It is unlikely that a holistic approach will be found to immediately change sexual-risk-relating behavior. Interventions including sustained educational programs, promotion of condom, and encouragement of voluntary testing and active involvement of the country’s political and religious leaders will be needed to alleviate this problem.

    As a result of the current exponentially growing refugee population from the Middle-East and East Africa (Sudan, Darfur, Eritrea), clinicians (including forensic pathologists) are seeing atypical skin lesions, mainly of a traumatic nature, but in some cases associated with long-standing lesions related to ethnic practices. A case of torture sequelae is presented herein in a patient originally from Darfur (Sudan): cutaneous incisions were made on old scars several times using a knife. The clinical presentation of scarification lesions and that of atypically healed wounds (presumably an effect of inflammation induced by the introduction of irritating foreign bodies such as sand, salt, etc.) are completely different: in all cases they indicate a relative timeframe of the facts, which the clinician should not overlook in reconstructing the patient's course and the injuries to which he has been subjected (hence the proposed designation of "palimpsest scar", in the sense that a palimpsest is a manuscript on a parchment that previously contained writing but has been scratched clean to be overwritten). Thus, a "palimpsest scar" constitutes a fresh scar on top of and hiding another (ritual) scar in a context of ethnic cleansing. The diagnostic and clinical significance comes from the importance of differentiating between ethnic-type lesions and those induced by physical violence and abuse in a context of war.

    Full Text Available Abstract Background Investigating use and determinants of family planning methods may be instructive in the design of interventions to improve reproductive health services. Findings Across sectional community-based study was conducted during the period February-April 2010 to investigate the use of family planning in Kassala, eastern Sudan. Structured questionnaires were used to gather socio-demographic data and use of family planning. The mean ± SD of the age and parity of 613 enrolled women was 31.1 ± 7 years and 3.4 ± 1.9, respectively. Only 44.0% of these women had previously or currently used one or more of the family planning methods. Combined pills (46.7% and progesterone injection (17.8% were the predominant method used by the investigated women. While age, residence were not associated with the use of family planning, parity (> five, couple education (≥ secondary level were significantly associated with the use of family planning. Husband objection and religious beliefs were the main reasons of non-use of family planning. Conclusion Education, encouragement of health education programs and involvement of the religious persons might promote family planning in eastern Sudan.

    Full text: Individual Monitoring Service (IMS) is a dosimetry service provided by Radiation Protection Department (RPD) of Sudan Atomic Energy Commission (SAEC) to monitor about 400 occupational exposed workers all over the country. Measurements were done using thermoluminescence dosimeters (TLD). The calibration of the TLD system was performed on a phantom with application of suitable correction factors in the SSDL using Cs-137 and different qualities of x-ray energies. Personal dose equivalents Hp(10) and Hp(0.07) were evaluated by employing one individual dosimeter to be carried continuously by the occupational exposed person while at work. In this work the dose received by workers in x-ray diagnostic radiology, radiotherapy, nuclear medicine, research and industrial radiography were evaluated. Radiation doses for the years 1999, 2000, 2001, 2002 and 2003 were compared. From the results obtained, it was noticed that individual monitoring service had expanded over the last years. The average individual annual dose in different applications is less than 1 mSv/y except for the workers in industrial radiography, only 12 radiation workers (3.64 %) received doses exceeding 1 mSv and no individual approached the dose limit of 20 mSv recommended by the ICRP and set by Sudan's regulations.

    International Nuclear Information System (INIS)

    2001-01-01

    Geography: Sudan is the largest country in Africa with a total area of 2.6M km 2 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.

  2. Spatial accessibility to basic public health services in South Sudan

    Directory of Open Access Journals (Sweden)

    Peter M. Macharia

    2017-05-01

    Full Text Available At independence in 2011, South Sudan’s health sector was almost non-existent. The first national health strategic plan aimed to achieve an integrated health facility network that would mean that 70% of the population were within 5 km of a health service provider. Publically available data on functioning and closed health facilities, population distribution, road networks, land use and elevation were used to compute the fraction of the population within 1 hour walking distance of the nearest public health facility offering curative services. This metric was summarised for each of the 78 counties in South Sudan and compared with simpler metrics of the proportion of the population within 5 km of a health facility. In 2016, it is estimated that there were 1747 public health facilities, out of which 294 were non-functional in part due to the on-going civil conflict. Access to a service provider was poor with only 25.7% of the population living within one-hour walking time to a facility and 28.6% of the population within 5 km. These metrics, when applied sub-nationally, identified the same high priority, most vulnerable counties. Simple metrics based upon population distribution and location of facilities might be as valuable as more complex models of health access, where attribute data on travel routes are imperfect or incomplete and sparse. Disparities exist in South Sudan among counties and those with the poorest health access should be targeted for priority expansion of clinical services.

    The aim of this study was to investigate the prevalence of obesity, dietary habits, and sedentary patterns among Sudanese adolescents. A multistage stratified sampling method was used to select 945 adolescents (507 males and 438 females) aged 14 to 18 years, from Khartoum State, Sudan. A self-reported pretested questionnaire was used to collect the data. Overweight and obesity were determined using the International Obesity Task Force standard, which is based on body mass index for sex and age. Overweight and obesity were growing problems among urban Sudanese adolescents (10.7%). Breakfast was commonly consumed on a daily basis by the majority of adolescents (74.2%), followed by lunch (63.9%) and supper (33.5%). Snacking was not a common practice among these individuals. Vegetables (63.9%) were more frequently consumed (more than 3 days per week) than fruit (30.1%). There were significant differences between genders regarding intake of vegetables (P Sedentary behaviors (long duration of television viewing and Internet use) were highly prevalent, and physical activity was rarely practiced (6.8%). The findings indicated that risk factors for diet-related chronic diseases such as unhealthy dietary habits and sedentary behaviors are starting to rise among urban adolescents in Sudan. This creates the need for immediate action to prevent and control these risk factors before these diseases become major public health problems. © The Author(s) 2016.

    To determine the effect of 7 days tactile kinesthetic stimulation (TKS) on preterm infants' weight and hospital stays in Khartoum State, Sudan. This is a quasi-experimental study, it was conducted in 4 hospitals between January and June 2013, Khartoum, Sudan, and it involved 160 preterm infants randomly assigned into the case and control groups (80 neonates in each). Preterm infants in the control group received routine nursing care, while preterm infants in the case group received TKS for 3 periods, 15 minute per day for 7 constitutive days, in addition to routine care. Data was collected using a structured self-designed and validated questionnaire, checklist, and weighting scale. Weight gain and hospital stay were compared between the 2 groups. Over the constitutive 7 days, the case group gained significantly more weight (1071 gm versus 1104 gm) compared with the control group (1077 gm versus 1084 gm) (1084.55±90.74) who gained only 6.9 gm within the same 7 days without TKS treatment. The mean difference in weight gain was significant (p=0.00). The hospital stay for preterm infants in the case group was significantly shorter (18.05±9.36 versus 25.47±10.25; p=0.00). Tactile kinesthetic stimulation for preterm infants has a beneficial effect on weight gain and earlier discharge from hospital, which are sequentially efficient and cost effective.

A total of 140 samples comprising of vaginal swab (n=97, placenta (n=15, whole blood (n=19, uterine fluid (n=1, and serum (n=8 were collected from 16 dairy herds showing particularly high rate of abortion and infertility in Khartoum State. The samples were used for virus isolation, and were tested by Enzyme-Linked Immunosorbent Assay (ELISA and polymerase chain reaction (PCR. No virus could be isolated from the samples inoculated for isolation in cell culture. Out of 80 specimens tested by ELISA, 7 (8.75% were found to be positive, and one sample was doubtful. Using PCR, 11 (10.7% out of 103 samples were found to be positive. When comparing between two methods for DNA extraction, the DNA extracted by commercial kit was found to be better in quality as compared to the DNA extracted using phenol/chloroform/isoamyl-alcohol method. The study confirmed the presence of BoHV-1 in cattle farms with reproductive problems in Sudan.

    2015-12-01

    Full Text Available Pathway analysis is a set of widely used tools for research in life sciences intended to give meaning to high-throughput biological data. The methodology of these tools settles in the gathering and usage of knowledge that comprise biomolecular functioning, coupled with statistical testing and other algorithms. Despite their wide employment, pathway analysis foundations and overall background may not be fully understood, leading to misinterpretation of analysis results. This review attempts to comprise the fundamental knowledge to take into consideration when using pathway analysis as a hypothesis generation tool. We discuss the key elements that are part of these methodologies, their capabilities and current deficiencies. We also present an overview of current and all-time popular methods, highlighting different classes across them. In doing so, we show the exploding diversity of methods that pathway analysis encompasses, point out commonly overlooked caveats, and direct attention to a potential new class of methods that attempt to zoom the analysis scope to the sample scale.

    2015-05-01

    Despite the increasing awareness of the importance of emerging vector-borne diseases, human tick-borne diseases, particularly rickettsial infections, are overlooked, especially in the countries such as Sudan with limited resources to perform molecular-based surveys. This study aimed at detection and genetic characterization of Rickettsia spp. in ticks collected from Sudan. The samples were first screened for the presence of rickettsial agents by gltA real-time PCR and subsequently characterized by gltA and ompA PCR and size-based multispacer typing. The results demonstrated the wide distribution of Rickettsia africae and/or closely related species across Sudan. The results of this report highlight the need for careful consideration of rickettsial infections in patients with nonmalarial febrile illness in this country. Nationwide surveillance on ticks associated with human rickettsial infections in Sudan is warranted.

    Turbulence and edge states are investigated numerically in a plane Poiseuille flow driven by a fixed pressure gradient. Simulations are carried out within the minimal flow unit, a concept introduced by Jiménez and Moin (1991 J . Fluid Mech. 225 213–40) to unravel the dynamics of near-wall structures in the absence of outer large-scale motions. For both turbulent and edge regimes the activity appears to be localised near only one wall at a time, and the long term dynamics features abrupt reversals. The dynamics along one reversal is structured around the transient visit to a subspace of symmetric flow fields. An exact travelling wave solution is found to exist very close to this subspace. Additionally the self-similarity of the asymmetric states is addressed. Contrary to most studies focusing on symmetric solutions, the present study suggests that edge states, when localised near one wall, do not scale in outer units. The current study suggests a composite scaling. (paper)

  7. The applicability of space imagery to the small-scale topographic mapping of developing countries: A case study — the Sudan

    Science.gov (United States)

    Petrie, G.; El Niweiri, A. E. H.

    After reviewing the current status of topographic mapping in Sudan, the paper considers the possible applications of space inagery to the topographic mapping of the country at 1 : 100,000 scale. A comprehensive series of tests of the geometric accuracy and interpretability of six types of space imagery taken by the Landsat MSS, RBV and TM sensors, the MOMS scanner, the ESA Metric Camera and NASA's Large Format Camera have been conducted over a test area established in the Red Sea Hills area of Sudan supplemented by further interpretation tests carried out over the area of Khartoum and the Gezira. The results of these tests are given together with those from comparative tests carried out with other images acquired by the same sensors over test areas in developed countries (UK and USA). Further collateral information on topographic mapping at 1 : 100,000 scale from SPOT imagery has been provided by the Ordnance Survey based on its tests and experience in North Yemen. The paper concludes with an analysis of the possibilities of mapping the main (non-equatorial) area of Sudan at 1 : 100,000 scale based on the results of the extensive series of tests reported in the paper and elsewhere. Consideration is also given to the infrastructure required to support such a programme.

  8. Disarmament, demobilisation and reintegration in South Sudan: The limits of conventional peace and security templates

    This report explores the DDR programme in South Sudan; in particular how it has evolved, what the major challenges have been to its implementation and, finally, what can realistically be expected from renewed efforts to disarm and reintegrate fighters vis-à-vis security imperatives on the ground. DDR has been identified as a main priority in the Republic of South Sudan and a prerequisite to pave the way for future stability and development. The basic argument presented here is that standard D...

    We adapted a rapid monitoring method to South Sudan, a new nation with one of the world's highest maternal and child mortality rates, aiming to assess coverage of maternal, neonatal and child health (MNCH) services at the time of independence, and introducing a monitoring and evaluation system (M&E) for equity-sensitive tracking of progress related to Millennium Development Goals (MDG) 4 and 5 at national, state and county levels to detect local variability. We conducted a national cross-sectional household survey among women from six client populations in all, but six of South Sudan's 79 counties. We used lot quality assurance sampling (LQAS) to measure coverage with diverse MNCH indicators to obtain information for national-, state- and county-level health system management decision-making. National coverage of MNCH services was low for all maternal and neonatal care, child immunisation, and child care indicators. However, results varied across states and counties. Central Equatoria State (CES), where the capital is located, showed the highest coverage for most indicators (e.g. ≥4 antenatal care visits range: 4.5% in Jonglei to 40.1% in CES). Urban counties often outperformed rural ones. This adaptation of LQAS to South Sudan demonstrates how it can be used in the future as an M&E system to track progress of MDGs at national, state and county levels to detect local disparities. Overall, our data reveal a desperate need for improving MNCH service coverage in all states. © 2015 The Authors.Tropical Medicine & International Health Published by John Wiley & Sons Ltd.

  10. Carbonization of some fast-growing species in Sudan

    1993-01-01

    Four wood species, indigenous Acacia seyal (talh) and exotic fast-growing Conocarpus lancifolius (damas), Eucalyptus microtheca (kafur) and Prosopis chilensis (mesquite) grown in Sudan, were assessed and compared as raw materials for charcoal making. The effects of production method (traditional earth mound and improved metal kiln) and the physical and chemical properties of the wood and bark on the yield and quality of charcoal produced were assessed. Regression analyses of wood properties and heat value data indicated high negative correlations of the wood heat value with halocellulose and ash, and high positive correlations with wood density, lignin, and alcohol-benzene and hot-water solubles. Carbonization with the Tropical Products Institute metal kiln produced higher yields (33%) than the traditional earth mound (27%), although the difference in energy transformation yields was found to be insignificant both between appliances and species.

  11. Holocene Lake and Shallow Water Sediments at Mograt Island, Sudan

    Directory of Open Access Journals (Sweden)

    Dittrich Annett

    2017-06-01

    Full Text Available This paper presents the results of stratigraphic excavation and soil studies carried out at Mograt Island, the largest of the Nilotic islands in Sudan. Due to its restricted insular environments, Holocene alluvial deposits were observed to be interlocked with archaeological remains of different periods, allowing for a combined chronostratigraphic approach to study both cultural and climatic events. To better understand the environmental context through soil components and pedological features at a microscopic scale, soil block samples were accordingly collected and studied by the application of soil micromorphology. This approach provides insights into the history of Nile terrace aggradation through the suspension of Nile sediment loads under stillwater conditions as well as of the periodical establishment of shallow water pools at the islands′ plateaus by the surface run-off from local rains. Since these patterns vary significantly from the present situation, they offer a key to the scenario in which specific early agricultural and animal herding practices evolved.

  12. CONTROL OF SCHISTOSOMIASIS IN THE GEZIRA IRRIGATION SCHEME, SUDAN.

    2017-01-01

    This paper analyses the changing patterns of infection with Schistosoma mansoni and S. haematobium in the Gezira Irrigation Scheme, Sudan. Taking a historical perspective, it shows the way in which factors such as ecology, biology, social and economic variables and politics have shaped patterns of infection, and how different kinds of strategies have been developed to control schistosomal infection over time. Wider political and economic issues at both national and international levels have shaped these strategies, influencing the prevalence and intensity of schistosomal infection at a local level. By highlighting the inter-play between the above-mentioned factors, the article reflects on the wisdom of prioritizing community-directed mass drug administration for the control of schistosomiasis in Gezira and elsewhere. The review demonstrates that not all efforts to control schistosomiasis are sustainable. A comprehensive control strategy involving political commitment, community participation and socioeconomic development is important for sustainable control of schistosomal infection.

    Full Text Available Sudan dyes (Table 1 [1], a class of synthetic azo dyes and classified as category 3 carcinogens by the International Agency for Research on Cancer[2], have been received considerable attention all over the world, especially in the past decade, which are found to be non-authorized and illegally added into food products, such as chili-, curry-, curcuma- and palm oil-containing foodstuffs, meats, spice mix, as well as feedstuffs and feed poultry, to enhance or maintain the appearance due to their intensive color and low price[3,4]. In addition, they are extensively applied in industrial and scientific areas, such as oils, textiles, plastics, waxes, inks, films, cosmetic products, shoe and floor polishing, and spirit varnishing[5-7]. Obviously, there exist a variety of potential sources for environmental contamination by Sudan dyes, thus threatening human health and the safety of ecosystems. It is reported that sub parts per billion levels of Sudan dyes were present in paprika fruits during the vegetation process, particularly, Sudan I existed in almost all samples, including paprika fruits, soils and agronomic materials from some fields in China[8],the levels in soils were significantly elevated by vegetation treatments, and pesticides and fertilizers constitute the major source of Sudan I contamination[9]. Till now, the investigation on contaminative behavior and environmental effects is rarely involved, and biogeochemical cycles of Sudan dyes are rarely concerned either.

    2014-10-01

    We adapted a rapid quality of care monitoring method to a fragile state with two aims: to assess the delivery of child health services in South Sudan at the time of independence and to strengthen local capacity to perform regular rapid health facility assessments. Using a two-stage lot quality assurance sampling (LQAS) design, we conducted a national cross-sectional survey among 156 randomly selected health facilities in 10 states. In each of these facilities, we obtained information on a range of access, input, process and performance indicators during structured interviews and observations. Quality of care was poor with all states failing to achieve the 80% target for 14 of 19 indicators. For example, only 12% of facilities were classified as acceptable for their adequate utilisation by the population for sick-child consultations, 16% for staffing, 3% for having infection control supplies available and 0% for having all child care guidelines. Health worker performance was categorised as acceptable in only 6% of cases related to sick-child assessments, 38% related to medical treatment for the given diagnosis and 33% related to patient counselling on how to administer the prescribed drugs. Best performance was recorded for availability of in-service training and supervision, for seven and ten states, respectively. Despite ongoing instability, the Ministry of Health developed capacity to use LQAS for measuring quality of care nationally and state-by-state, which will support efficient and equitable resource allocation. Overall, our data revealed a desperate need for improving the quality of care in all states. © 2014 John Wiley & Sons Ltd.

  15. Plain radiography procedures in Sudan: examination frequency and collective dose

    Musa, B. E. Y.

    2010-12-01

    According to the previous studies diagnostic examinations are the largest man-made source to collective dose (CED) in world. It was observed that, despite of the large number of medical x-ray installations in Sudan and in particular conventional x-ray procedures, studies aimed at estimating collective effective dose in diagnostic radiology were lacking. The purpose of this study was to estimate the annual frequency of plain radiography examinations and to estimate the annual collective effective dose to Sudanese population due to plain radiography examinations, selected by their high frequencies or their relatively high doses delivered to patient. To have an idea about the typical examinations frequencies, data were collected from a sample of ten hospitals in Khartoum. The collected data provided information about the x-ray machine manufacture, year of installation and frequency of some examinations per day. The annual collective doses from all medical examinations to the population are: 441, 166, 630, 544, 276, 525, 30, 9, 12 and 161 man Sv from abdomen AP, chest AP, pelvis, lumbar spine PA, lumbar spain PA, lumbar- sacral joints, Skull AP, Skull LAT, Skull PA and from others examination, respectively. The resulting annual collective effective dose was evaluated 2793 man Sv, with the largest contribution of pelvis and LS examinations and lowest contribution of skull examinations. Collective effective dose resulting from the use of plain radiography examinations in the Sudan is small compared with global results. But that dose not negate the need to conduct radiological surveys in frequent intervals to meet the increase of successive x-ray equipment to try to estimate and reduce the doses of patients and the public.

  16. HIV/AIDS: Knowledge, attitudes and practices among adolescents in Nimule, South Sudan

    Directory of Open Access Journals (Sweden)

    Michael Bol Jool Dit

    2018-02-01

    Full Text Available Background: HIV is an infectious virus commonly transmitted through body fluids mostly semen and blood. It causes a serious and non-curable disease with grave consequences especially in sub-Saharan Africa. In South Sudan the prevalence rate of HIV was estimated at 2.6% in 2016. The treatment options are scarce and educational programs limited. This is of great concern since limited knowledge and awareness of HIV is a major risk factor particularly, among young people. Method: A cross-sectional survey using self-administered questionnaires among adolescents was carried out in November 2016. Results: Sixty-five students participated in the study. In general they had good knowledge about HIV/AIDS with the majority having heard of HIV. Majority stated that HIV spreads through sex (82%, blood transfusion (95%, and from mother to child during pregnancy and delivery (66%. Several misconceptions were present with 43% responding that HIV can be transmitted through mosquito bites and 18% stating that the virus can be spread through shaking hands, hugging and living in the same house. Conclusion: Though the respondents showed fair knowledge about HIV/AIDS, there are still some areas in which they lack knowledge especially regarding spread of the disease and practice. More information about HIV/AIDS and sexual education should be made available.

    2013-01-01

    We propose a scheme capable of performing complete Bell-state analysis for a single-photon hybrid entangled state. Our single-photon state is encoded in both polarization and frequency degrees of freedom. The setup of the scheme is composed of polarizing beam splitters, half wave plates, frequency shifters, and independent wavelength division multiplexers, which are feasible using current technology. We also show that with this setup we can perform complete two-photon Bell-state analysis schemes for polarization degrees of freedom. Moreover, it can also be used to perform the teleportation scheme between different degrees of freedom. This setup may allow extensive applications in current quantum communications

    Few studies have focused on the bacterial species associated with the deterioration of the dental and gingival health of children with congenital heart defects (CHD). The aims of this study were (1) to examine the dental plaque of children with CHD in order to quantify bacterial load and altered bacterial composition compared with children without CHD; and (2) to investigate the correlation between the level of caries and gingivitis and dental biofilm bacteria among those children. In this cross-sectional study, participants were children (3-12 years) recruited in Khartoum State, Sudan. A total of 80 CHD cases from the Ahmed Gasim Cardiac Centre and 80 healthy controls from randomly selected schools and kindergartens were included. Participants underwent clinical oral examinations for caries (decayed, missing, and filled teeth indices [DMFT] for primary dentition, and DMFT for permanent dentition), and gingivitis (simplified gingival index [GI]). Pooled dental biofilm samples were obtained from four posterior teeth using paper points. Real-time quantitative polymerase chain reaction was used for the detection and quantification of Streptococcus mutans , Streptococcus sanguinis, and Lactobacillus acidophilus . Checkerboard DNA-DNA hybridization was used for the detection of 40 additional bacterial species. CHD cases had a significantly higher caries experience (DMFT = 4.1 vs. 2.3, p  bacterial species exhibited significantly higher mean counts among CHD cases ( p  bacterial species in their dental plaque, which correlated with higher levels of caries and gingivitis.

    1992-01-01

    The country programme summary reported here is one in the series of such studies being undertaken of the Agency's TC programme with Member States. With over $5.7 million of Agency support received, Sudan ranks 31st among all recipients of technical assistance in the period 1958 through 1991. Over the past ten years, almost equal shares of this assistance were provided in the form of equipment (46%) and training (42%), and only a small percentage was provided in the form of expert services (12%). The best part of the resources was made available through the Technical Assistance and Co-operation Fund (77%), while in-kind and extrabudgetary contributions account for 13% and 10% of the resources, respectively. With regard to project disbursement during the past ten years, by sector, the two largest areas have been general atomic energy development (37%) and agriculture (21%), followed by nuclear medicine (14%). Smaller shares (6% each) have gone to nuclear physics and chemistry, nuclear engineering and technology, hydrology, and nuclear safety

  8. Local justice and power of an official nature in Southern Sudan

    Directory of Open Access Journals (Sweden)

    Cherry Leonardi

    2009-12-01

    Full Text Available In this article, the author examines the growing ambiguity that characterises the administration of justice in southern Sudan since an autonomous government was set up, thanks to the 2005 peace agreement. While the State was a distant, separate body owing to the monopoly exerted over it by the peoples of the North, its courts of justice, precarious though they might be, could be viewed in the South as an agent that is neutral, albeit distant from local power networks: it was considered to be the hakuna sphere of power, to which people would only resort after the closest systems of conflict resolution (based on family ties had failed. However, the creation of an autonomous government has brought the hakuna sphere closer to local reality, creating interferences between two realities that had become accustomed to functioning in a parallel manner. This new situation has generated new dynamics as regards how to react to local conflicts and also, logically, with respect to how to go about resolving them.

    2016-01-01

    This study is aimed to determine trace elements concentrations (Ca, Cu, Cr, K,Fe, Mn, Ni, Sr and Zn) in Grewia tenax collected from Darfur state western of Sudan. X- ray fluorescence (X RF) technique was used to determine elements concentration. A series of plant standard reference materials(ISE 2012-1) were used to check the reliability of employed technique by comparing the obtained results with the certified values, to estimate possible factors for correcting the concentration of some elements. The results showed that, X RF is a suitable method for measuring Ca, Cu, K, Fe, Mn, Sr and Zn elements. On the other hand, X RF for Cr and Ni determination in plant samples, these elements have showed a deviation from their certified values. Concentration of Fe was about 35 mg/kg in Grewia tenax samples where as K and Ca showed maximum levels about 16000 and 8500 mg/kg respectively, Cu showed minimum concentration about 10 mg/kg. The effect of geographical location on trace elements concentration in plants has been examined through determination of element in different species of Grewia tenax that collected from different locations in Darfur region. Most of the measured elements showed that there is no significant impact of locations on the difference of element contents.(Author)

  10. The Disintegration of the Military Integration Process in South Sudan (2006–2013

    Directory of Open Access Journals (Sweden)

    Lesley Anne Warner

    2016-09-01

    Full Text Available This article argues that military integration served a critical purpose in 2006, arguably preventing large-scale conflict within South Sudan and ensuring a level of stability prior to the CPA-mandated referendum on self-determination in 2011. Nonetheless, integration was poorly-conceived and implemented, and received limited support from third party actors that were more focused on rightsizing the SPLA and transforming it into a conventional, professional military. The de facto open-door nature of South Sudan’s integration process created incentives for armed rebellion, while failed rightsizing initiatives increased pressure on the military integration process as the most expedient way of mitigating the threat these groups posed to stability. Integration thus became an end in and of itself rather than a transitional measure to contain former combatants while the government worked out a more long-term solution for South Sudan’s security sector. Consequently, the SPLA was in a state of arrested development, preventing efforts to transform the military from gaining traction, and making the force more likely to fragment along factional lines during periods of heightened political competition.

  11. Studies of the incidence of post-operative deep-vein thrombosis in Sudan, using 125I-fibrinogen

    Hassan, M.A.

    1974-01-01

    Sudanese patients undergoing surgery in Khartoum Civil Hospital were investigated for evidence of post-operative deep vein thrombosis by means of the 125 I-fibrinogen test. An analysis of the results obtained in an initial series of 100 patients undergoing various operations including prostatectomy (transvesical or retropubic), vagotomy and drainage, cholocystectomy, various operations on the urinary bladder, various operations on the hip, splenectomy, herniorrhaphy, nephrectomy and haemorrhoidectomy revealed an incidence of post-operative deep vein thrombosis of 12.0%. There was no significant variation of incidence with age or sex. A subsequent analysis of the results obtained in 104 patients undergoing prostatectomy (transvesical or retropubic) revealed an incidence of deep vein thrombosis of 9.6%. These values differ markedly from the incidences of 21-47% reported in Sweden and UK. It is suggested that the indicence of post-operative deep vein thrombosis is lower in Sudan than in European countries

    Directory of Open Access Journals (Sweden)

    Anne Walraet

    2008-10-01

    Full Text Available This article analyses how Budi County in Eastern Equatoria State (South Sudan was governed during the 1990s and up to mid-2007. Because its capital Chukudum was the SPLM/A headquarters almost throughout that period, it provides us with an interesting case from which to explore how the SPLM/A governed during the war and how this impacts on the post-war peace. One observation is that the war, besides a period of devastation and human suffering, was also a time of economic opportunities and social differentiation. For that reason this article will also explore livestock trade as a new mode of wealth appropriation and the changing nature of cattle raiding, and how this interferes with the struggle for regulatory power and governable “spaces”. This means that we comprehend the economy as a political terrain. At the same time we leave room for sociological perspectives, to complement the more restricted “competition for resources and gains” approach to conflict and violence. The article is written in three sections. In the first section we briefly clarify why in 1999 there was an uprising in Budi County against SPLM/A rule and why it engendered massive local support. In the second section we examine one of the most destructive manifestations of violence that affect Budi county: cattle raiding. We look at it from a perspective that has been under-researched in the eld: that of trans-border trade. In the last section we look at how, after the peace of 2005, newly appointed local government authorities are (reclaiming do- mains of state regulation that previously lay rmly in the hands of the military. Particular attention is given to the capacity of the local authorities to guarantee security and provide protection.

    The challenges presented by traumatic injuries in low-resource communities are especially relevant in South Sudan. This study was conducted to assess whether a 3-day wilderness first aid (WFA) training course taught in South Sudan improved first aid knowledge. Stonehearth Open Learning Opportunities (SOLO) Schools designed the course to teach people with limited medical knowledge to use materials from their environment to provide life-saving care in the event of an emergency. A pre-test/post-test study design was used to assess first aid knowledge of 46 community members in Kit, South Sudan, according to a protocol approved by the University of New England Institutional Review Board. The course and assessments were administered in English and translated in real-time to Acholi and Arabic, the two primary languages spoken in the Kit region. Descriptive statistics, t-test, ANOVA, and correlation analyses were conducted. Results included a statistically significant improvement in first aid knowledge after the 3-day training course: t(38)=3.94; Pfirst of its kind in South Sudan, provides evidence that a WFA training course in South Sudan is efficacious. These findings suggest that similar training opportunities could be used in other parts of the world to improve basic medical knowledge in communities with limited access to medical resources and varying levels of education and professional experiences.

  16. Conflicts in the Horn of Africa and their Consequences on Sudan's Stability and Security

    Directory of Open Access Journals (Sweden)

    Elfatih Abdullahi Abdel Salam

    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.

    Full Text Available Objective: To study risk factors associated with post partum haemorrhage (PPH in Juba Teaching Hospital, South Sudan. Method: An unmatched case control study was conducted in which 44 cases and 88 Controls were involved, from September to December 2011. Data was collected using a structured questionnaire in face to face interviews, and analyzed using Epi-info 3.5.3 statistical programme to determine if there was a correlation. Results: Maternal demographic and obstetric characteristics were found to be associated with the risk of bleeding during Bivariate analysis. However, age was found to confound emergency admission, uterotonic use (Oxytocin and Misoprostol use and delivery type, the latter being modified, in the development of post partum haemorrhage. Conclusion: These results indicate that active management of the third stage of labour (AMTSL and prompt intervention reduced the risk of developing PPH. Understanding the factors that cause PPH will allow us to better strengthen and effect pre delivery and emergency obstetric care which may help us reduce maternal mortality due to post partum haemorrhage.

    Thermoluminescence dating of a set of 29 pottery sherds excavated at the neolithic sites of El Kadada and El Ghaba (near Shendi, Central Sudan) was carried out at Bordeaux University. The archaeological dose was measured using the fine grain technique. The annual dose was determined by analytical techniques (neutron activation analysis, ICP spectrometry, XRF, low background gamma spectrometry) and by ''on-site'' measurements of the environmental radioactivity (gammametry). The crystalline inclusions of the samples were characterized by optical microscopy and cathodoluminescence: the TL minerals mainly consist of quartz and K-feldspar crystals. In some cases, radioactive inclusions of zircons and monazites are observed. The TL and the radiocarbon dates show a good agreement, verifying the validity of the radiocarbon ages which were suspected to be too old because of the nature of the dated material (shells). Taking into account all the chronological data, it is shown that El Ghaba and El Ghaba necropolis were used respectively within the 4800-3300 B.C. and 4200-3000 B.C. date-ranges for neolithic cultures, the occupation of El Kadada starting five or six centuries later than El Ghaba.

    The purpose of this study was to assess patient radiation dose during fluoroscopy examinations using contrast media in Sudan. Data was collected from the Department of Radiology of the Military Hospital in Omdurman. The quality control tests on the Fluoroscopy machine indicated that it is performing self-consistently. The patient doses were obtained from measurements made using Kerma Area Product (KAP) meter. Measurements were made on sixty patients. The special examinations considered were hysterosalpinogram (HSG), A sanding (A.S), D.Standing (D.S) , Gastrointestinal (G.I) tract and Sinogram. The KAP meter readings obtained were 2.68 ±1.80 mGy.m 2 ; 5.16 ±3.53 mGy.m 2 ; 9.15 ± 3.53 mGy.m 2 ; 5.80 ±6.22 mGy.m 2 and 10.33 ±10.69 mGy.m 2 respectively. Improved patient protection can be achieved by the adoption of standardized and optimized institutional protocols using equipment with an integrated dose management system. The cumulative reference point air-kerma data, along with KAP, should be routinely recorded in the patient records for trend analysis to provide the means to enhance optimization of patient protection in fluoroscopy practice.

    Full Text Available Objectives: There is increasing awareness about the effects of circadian misalignment on health and work. In the present study, we aimed to investigate the effects of chronotype on academic achievement among medical students. Methods: A cross-sectional comparative study was conducted among 140 medical students (64 who averaged an A grade and 76 who averaged a C grade completing the clinical phase at the medical college of Omdurman University, Sudan. The participants were asked to sign a written informed consent and to keep a diary detailing their bedtime, wake-up time, sleep latency, and sleep duration during working days and weekends. Then, the participants were invited to respond to a questionnaire. The chronotype was calculated from the mid-sleep time during the weekend and sleep debt. Various sleep parameters were then compared between the two groups. A t-test and logistic regression analysis were used to test the statistical significance. Results: The medical students with average grades were more of the evening chronotype than the students with excellent grades (p  0.05. Conclusion: Students whose average grade was a C were more likely to have a later bedtimes during weekdays and weekends, sleep more during weekends, and were more evening.

    The negative impact of war is apparent at various levels of the Sudanese society. Economic, social, and political instability is occurring on a large scale and the most vulnerable groups are women and children. This report aimed to document women's human rights violations in the ongoing armed conflict situation in Sudan, with the emphasis on rape; investigate the forms of violence against women in a situation of armed conflict; present testimonies of women survivors; and use the document for advocacy. A total of 20 testimonies were obtained, which clearly indicated that rape is a systematic practice in areas of conflict regardless of whether the Sudanese People's Liberation Army, the Khartoum government, or bandit groups that take advantage of the chaos, have attacked civilians. In view of this, regional agencies should show more seriousness in finding solutions for the war, and perpetrators of rape should be brought to justice so as to change the perception of rape as an unfortunate but inevitable side effect of war.

    1996-01-01

    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)

    2011-01-01

    Endoscopic retrograde cholangiopancreatography (ERCP) procedure is an invasive technique that requires fluoroscopic and radiographic exposure. The purpose of this study was to determine the occupational dose of ionising radiation at three gastroenterology departments (Fedial, Soba and Ibn seena hospitals) in Khartoum (Sudan). The radiation dose was measured during 55 therapeutic ERCP procedures. Thermoluminescence dosemeters were used. The mean radiation dose for the first operator was 0.27 mGy for the eye lens, 0.21 for the thyroid, 0.32 for the chest, 0.17 for the hand and 0.22 for the leg. The mean radiation dose for the second operator was 0.21 mGy for the hand and 0.20 mGy for the chest, while the mean radiation dose for the nurse was 0.44 mGy for the hand and 0.19 for the chest. The radiation dose received by the staff in these hospitals was found to be higher than most of the values in the literature. The radiation absorbed dose received by the different organs is relatively low. Additional studies need to be conducted for radiation dose optimisation. (authors)

    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 2 38U , 2 32T h and 4 0K 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.

    1988-01-01

    Field cylinders as described in the model experiment for determination of 14 C-DDT in Sudan Gezira soil were prepared and samples were collected for determination of 14 C-activity at various intervals. About 83-87% of the applied radioactivity was recovered in the extracts from the top 10 cm layer of soil. The loss rate of the chemical from soil increased with time apparently by volatilization and thermal degradation due to high soil temperature, intensive solar radiation and low soil organic matter. This resulted in a half-life of approx. 5 weeks. The major part of the chemical and possible metabolites were detected in the top 10 cm layer. Approximately 8-10% of the applied 14 C was detected in samples collected after 16-20 weeks. TLC and autoradiography indicated the presence of p,p'-DDT and p,p'-DDE as the major metabolite. Also traces of TDE were detected in some samples. These results showed that under Sudanese tropical conditions, DDT dissipates very rapidly in soils compared to dissipation in temperate regions.

    Children are more radio sensitive than adult. This study aims to assess radiation doses and the associated hazards to pediatric during cardiac catheterization procedures. Radiation dose for 112 patients was estimated in the biggest cardiac center in Sudan. The median KAP in Gy cm"2, CK in mGy, number of frames and fluoroscopy time in minutes were (4.6, 29.0, 340.4, 13.5) and (6.0, 35.0, 318, 9.8) for the diagnostic and therapeutic cardiac procedures, respectively. The median (KAP in Gy cm"2, effective dose in mSv) for different age groups in the intervals of less than 1 year, 1-<5 years, 5-<10 years and 10- 15 years old were (2.2, 4.4), (2.5, 5.0), (4.2, 5.1) and (8.5, 4.1) respectively. Including all the procedures using the multiplicative model of ICRP 60, the mean attributable lifetime risk for stochastic effect was 0.08 and 0.05% for girls and boys, respectively. Training is needed to raise staff awareness about radiation protection. (authors)

    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

    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 P O5 %) 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)

    Full Text Available The Islamic State’s recent losses on the battlefield, including significant casualties within its media and propaganda division, offer a unique opportunity to inject competing and alternative messages into the information space. This paper proposes that the content of such messages should be guided by a linkage-based analysis of existing Islamic State messaging. A linkage-based analysis of a top-level 2017 audio message by Islamic State spokesperson Abu Hasan al Muhajir offers several potential insights into crafting effective content for competing and alternative messages. A comparison of the 2017 work to earlier Islamic State messaging also reveals specific opportunities to undermine the credibility of the organisation’s broader propaganda programme by highlighting the organisation’s repeated failure to follow through on its extravagantly promised commitment to achieving its stated goals.

    Full Text Available Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6 % of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e. the number of infected acini / number of infected ticks. At Wad-Medani, 8.6 % of 162 ticks were infected and the mean intensity of infection was 7.9. The prevalence of infection was higher in female than in male ticks at both localities. When adult H. a. anatolicum were applied onto two susceptible calves, both animals developed the severe form of theileriosis.

    2013-01-01

    There is a large disparity in the amount of wind power capacity installed in each of the states in the U.S. It is often thought that the different policies of individual state governments are the main reason for these differences, but this may not necessarily be the case. The aim of this paper is to use statistical methods to study the factors that have the most influence on the amount of installed wind capacity in each state. From this analysis, we were able to use these variables to accurately predict the installed wind capacity and to gain insight into the driving factors for wind power development and the reasons behind the differences among states. Using our best model, we find that the most important variables for explaining the amount of wind capacity have to do with the physical and geographic characteristics of the state as opposed to policies in place that favor renewable energy. - Highlights: • We conduct a statistical analysis of factors influencing wind capacity in the U.S. • We find that state policies do not strongly influence the differences among states. • Driving factors are wind resources, cropland area, and available percentage of land

    The inquisitiveness about what happens in the brain has been there since the beginning of humankind. Functional magnetic resonance imaging is a prominent tool which helps in the non-invasive examination, localisation as well as lateralisation of brain functions such as language, memory, etc. In recent years, there is an apparent shift in the focus of neuroscience research to studies dealing with a brain at 'resting state'. Here the spotlight is on the intrinsic activity within the brain, in the absence of any sensory or cognitive stimulus. The analyses of functional brain connectivity in the state of rest have revealed different resting state networks, which depict specific functions and varied spatial topology. However, different statistical methods have been introduced to study resting state functional magnetic resonance imaging connectivity, yet producing consistent results. In this article, we introduce the concept of resting state functional magnetic resonance imaging in detail, then discuss three most widely used methods for analysis, describe a few of the resting state networks featuring the brain regions, associated cognitive functions and clinical applications of resting state functional magnetic resonance imaging. This review aims to highlight the utility and importance of studying resting state functional magnetic resonance imaging connectivity, underlining its complementary nature to the task-based functional magnetic resonance imaging.

  19. 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.

    Wang, Lihui

    2014-01-01

    With the increasing complexity and dynamism in today’s machine design and development, more precise, robust and practical approaches and systems are needed to support machine design. Existing design methods treat the targeted machine as stationery. Analysis and simulation are mostly performed at the component level. Although there are some computer-aided engineering tools capable of motion analysis and vibration simulation etc., the machine itself is in the dry-run state. For effective machine design, understanding its thermal behaviours is crucial in achieving the desired performance in real situation. Dynamic Thermal Analysis of Machines in Running State presents a set of innovative solutions to dynamic thermal analysis of machines when they are put under actual working conditions. The objective is to better understand the thermal behaviours of a machine in real situation while at the design stage. The book has two major sections, with the first section presenting a broad-based review of the key areas of ...
