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 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.

Full Text Available Aim: This cross-sectional survey was conducted to detect anti- N. caninum antibodies in bovine dams' sera samples in nine States of the Sudan. Materials and Methods: Two hundred and seventy six bovine dams' sera samples collected from nine States in the Sudan were screened for anti-Neospora caninum antibodies using a commercial competitive ELISA (cELISA kits. Results: The results showed an overall prevalence rate of 15.9% (range 6.7% - 70% of Neospora caninum antibodies. The prevalence rates were high in White Nile (70% and North Kordofan (30%, moderate in the Northern (15.6%, Red Sea (13.3% States and was low in the South Kordofan (9.4% and River Nile (6.7%. States with high values of percentage inhibition (PI detected in White Nile State compared to other States. No antibodies were detected in El Gadarif, Kassala and South Darfur States. 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

Natural infection rates and transmission of Theileria annulata by Hyalomma anatolicum anatolicum ticks in the Sudan

2005-09-01

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.

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)

Dosimetric studies based on the radiation-induced bleaching of Sudan red and Sudan blue dyes in organic solutions

International Nuclear Information System (INIS)

Souka, N.; Farag, A.N.

1990-01-01

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.

2000-01-01

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)

Spatial and temporal distribution of the malaria mosquito Anopheles arabiensis in northern Sudan: influence of environmental factors and implications for vector control

2009-06-01

Full Text Available Abstract Background Malaria is an important public health problem in northern Sudan, but little is known about the dynamics of its transmission. Given the characteristic low densities of Anopheles arabiensis and the difficult terrain in this area, future vector control strategies are likely to be based on area-wide integrated pest management (AW-IPM that may include the sterile insect technique (SIT. To support the planning and implementation of future AW-IPM activities, larval surveys were carried out to provide key data on spatial and seasonal dynamics of local vector populations. Methods Monthly cross-sectional larval surveys were carried out between March 2005 and May 2007 in two localities (Dongola and Merowe adjacent to the river Nile. A stratified random sampling strategy based on the use of Remote Sensing (RS, Geographical Information Systems (GIS and the Global Positioning System (GPS was used to select survey locations. Breeding sites were mapped using GPS and data on larval density and breeding site characteristics were recorded using handheld computers. Bivariate and multivariate logistic regression models were used to identify breeding site characteristics associated with increased risk of presence of larvae. Seasonal patterns in the proportion of breeding sites positive for larvae were compared visually to contemporaneous data on climate and river height. Results Of a total of 3,349 aquatic habitats sampled, 321 (9.6% contained An. arabiensis larvae. The frequency with which larvae were found varied markedly by habitat type. Although most positive sites were associated with temporary standing water around the margins of the main Nile channel, larvae were also found at brickworks and in areas of leaking pipes and canals – often far from the river. Close to the Nile channel, a distinct seasonal pattern in larval populations was evident and appeared to be linked to the rise and fall of the river level. These patterns were not

A sudden onset of cholera in South Sudan, in April 2014 in Northern Bari in Juba town resulted in more than 400 cholera cases after four weeks of initial outbreak with a case of fatality rate of CFR 5.4%. The total number of reported cholera cases for the period of April to July, 2014 were 5,141 including 114 deaths. With the limited efficacy of cholera vaccines, it is necessary to develop mechanisms to predict cholera occurrence and thereafter devise intervention strategies for mitigating impacts of the disease. Hydroclimatic processes, primarily precipitation and air temperature are related to epidemic and episodic outbreak of cholera. However, due to coarse resolution of both datasets, it is not possible to precisely locate the geographical location of disease. Here, using Land Surface Temperature (LST) from MODIS sensors, we have developed an algorithm to identify regions susceptible for cholera. Conditions for occurrence of cholera were detectable at least one month in advance in South Sudan and were statistically sensitive to hydroclimatic anomalies of land surface and air temperature, and precipitation. Our results indicate significant spatial and temporal averaging required to infer usable information from LST over South Sudan. Preliminary results that geographically location of cholera outbreak was identifiable within 1km resolution of the LST data.

Evaluation of normal values of Ca-15-3 and PSA for the people of Northern State of Sudan

Bafaraj, S.M.I.

2007-06-01

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 Status of Women in Physics in Sudan

2009-04-01

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.

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)

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).

Sudan.

1984-05-01

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.

2013-07-01

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.

2014-12-01

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.

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 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.

Determination of Aniline Degraded From Sudan I in Cloths

Wei, C.K.; Fung, L.C.; Men, C.K.

2013-01-01

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)

Geology and geophysics of the West Nubian Paleolake and the Northern Darfur Megalake (WNPL-NDML): Implication for groundwater resources in Darfur, northwestern Sudan

Science.gov (United States)

Elsheikh, Ahmed; Abdelsalam, Mohamed G.; Mickus, Kevin

2011-08-01

The recent delineation of a vastly expanded Holocene paleo-lake (the Northern Darfur Megalake which was originally mapped as the West Nubian Paleolake and here will be referred to as WNPL-NDML) in Darfur in northwestern Sudan has renewed hopes for the presence of an appreciable groundwater resource in this hyper-arid region of Eastern Sahara. This paleolake which existed within a closed basin paleo-drainage system might have allowed for the collection of surface water which was subsequently infiltrated to recharge the Paleozoic-Mesozoic Nubian Aquifer. However, the presence of surface exposures of Precambrian crystalline rocks in the vicinity of the paleolake has been taken as indicating the absence of a thick Paleozoic-Mesozoic sedimentary section capable of holding any meaningful quantity of groundwater. This work integrates surface geology and gravity data to show that WNPL-NDML is underlain by NE-trending grabens forming potential local Paleozoic-Mesozoic aquifers that can hold as much as 1120 km 3 of groundwater if the sedimentary rocks are completely saturated. Nevertheless, it is advised here that recharge of the Nubian aquifer under WNPL-NDML is insignificant and that much of the groundwater is fossil water which was accumulated during different geological times much wetter than today's hyper-arid climate in Eastern Sahara. Excessive extraction will lead to quick depletion of this groundwater resource. This will result in lowering of the water table which in turn might lead to the drying out of the oases in the region which provide important habitats for humans, animals and plants in northern Darfur.

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.

Currency Crisis in Sudan in 2012: An Econometric Analysis

Directory of Open Access Journals (Sweden)

Alamedin Bannaga, Dr.

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.

Rapid fluorescence assay for Sudan dyes using polyethyleneimine-coated copper nanoclusters

International Nuclear Information System (INIS)

Ling, Yu; Li, Jia Xing; Li, Nian Bing; Luo, Hong Qun; Qu, Fei

2014-01-01

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)

Sudan dyes are banned to be used in food additives because of the carcinogenicity of their metabolites. A rapid and sensitive indirect competitive enzyme-linked immunosorbent assay (ELISA) was developed to detect the residues of Sudan dyes. Novel immunogen and coating antigen were synthesized via glutaraldehyde linking. The hapten-bovine serum albumin (BSA) was applied as immunogen and the hapten-ovalbumin (OVA) was served as coating antigen. The monoclonal antibody obtained showed high sensitivity to Sudan I with an IC(50) value of 1.7 μg L(-1) in buffer and was suitable to detect the residues of Sudan red in food products. The specificity of the assay was studied by measuring cross-reactivity of the antibody with the structurally related compounds of Sudan II (red (120%). Chilli jam and chilli oil samples spiked with Sudan dyes were analyzed by the method. The detection limit (LOD) of the ELISA method applied in chilli jam and chilli oil was 9.0 μg L(-1) and 19.6 μg L(-1), respectively. The recovery rates of Sudan-I in chilli oil and chilli jam were in the range of 80%-110% with coefficients of variation <25%. The intra-assay variation and inter-assay variation in buffer were both <9%.

Chemical control of wild sorghum (sorghum arundinaceum Del. Stapf. in faba bean (vicia faba L.) in the Northern State of Sudan

International Nuclear Information System (INIS)

Bedry, K. A. M.; Elamin, A. E. M.

2011-01-01

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)

Powerlessness, Normalization, and Resistance: A Foucauldian Discourse Analysis of Women's Narratives On Obstetric Fistula in Eastern Sudan.

Science.gov (United States)

Hamed, Sarah; Ahlberg, Beth-Maina; Trenholm, Jill

2017-10-01

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.

131I levels in cow's milk following ingestion of contaminated alfalfa or sudan grass

International Nuclear Information System (INIS)

Black, S.C.; Stanley, R.E.; Barth, D.S.

1975-08-01

A dry aerosol, consisting of submicrometer diatomaceous earth particles tagged with 131 I, was released over two different types of growing forage (alfalfa and Sudan grass) at the Experimental Dairy Farm on the Nevada Test Site. Following deposition of the aerosol, the two forage types were chopped and fed to different groups of lactating dairy cows. The dual objectives of the study were to evaluate the relationship of 131 I secretion in milk to the ingestion of different types of contaminated forage and to obtain a further indication of the possible influence on milk radioiodine levels of changing the particle size of the contaminant. The ratios of the peak activity concentrations measured in the milk to the peak activity concentrations in the forage were computed to be 0.0145 for the cows fed contaminated alfalfa and 0.0082 for those fed contaminated Sudan grass. Comparison of the results from this study with those from earlier studies indicates the major effect on activity levels in the milk can be related to forage type. Ingestion of Sudan grass by the cow reduces the transfer of radioiodine to milk by one half compared to ingestion of alfalfa. (U.S.)

Polar and low polar solvents media effect on dipole moments of some diazo Sudan dyes

Science.gov (United States)

Zakerhamidi, M. S.; Golghasemi Sorkhabi, Sh.; Shamkhali, A. N.

2014-06-01

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.

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.

• Adansonia digitata L. is one of the most important indigenous fruit trees of mainland Africa. Despite its significance for subsistence and income generation of local communities, little is known about the genetic and morphological variability of East African populations of A. digitata, including those of Sudan. The aim of the current study, therefore, was to analyze genetic and morphological variability of different baobab populations in Kordofan, Sudan and to estimate the effect of human intervention on genetic differentiation and diversity.• A total of 306 trees were randomly sampled from seven spatially separated locations in the Nuba Mountains, Sudan, to cover a wide range of differing environmental gradients and management regimes ('homesteads' and 'wild'). Genetic analyses were conducted using nine microsatellite markers. Because of the tetraploid nature of A. digitata, different approaches were applied to estimate patterns of genetic diversity. Investigations were completed by measurements of dendrometric and fruit morphological characters.• Genetic diversity was balanced and did not differ between locations or management regimes, although tendencies of higher diversity in 'homesteads' were observed. A Bayesian cluster approach detected two distinct gene pools in the sample set, mainly caused by one highly diverse population close to a main road. The variability of tree characters and fruit morphometries was high, and significantly different between locations.• Results indicated a rather positive effect with human intervention. The observed populations provide a promising gene pool and likely comprise ecotypes well-adapted to environmental conditions at the northern distribution range of the species, which should be considered in conservation and management programs. © 2014 Botanical Society of America, Inc.

The Impact of Conflict on Forests in South Sudan

Gorsevski, V.; Kasischke, E. S.; Dempewolf, J.; Loboda, T. V.; Geores, M.

2014-12-01

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.

Talisman Energy Inc. is a large independent Canadian oil and gas producer with operations worldwide, including operations in Sudan, Malaysia, Trinidad and Colombia. This report includes a discussion on seismic exploration in the Acevedo block in Colombia, but most of the report focuses on operations in Sudan because that is the primary concern of many stakeholders, particularly the impact of the long-running civil war in that country and the way in which oil revenues will be used. The report describes Talisman Energy's compliance with the International Code of Ethics for Canadian Business which Talisman adopted in December 1999. The report evaluates Talisman's progress towards achieving objectives in the areas of human rights, community participation, employee rights, ethical business conduct, health, safety and the environment. Talisman will continue to advocate peace and the fair distribution of oil revenues. It was noted that the funding provided by the Sudan oil project consortium Greater Nile Petroleum Operating Company (GNPOC) for community development was increased for 2002. Talisman and GNPOC funding helps in community development initiatives such as the provision of water wells, health clinics and schools in Sudan. PricewaterhouseCoopers (PwC) was asked by Talisman to gather comments on the company's operations in Sudan from a range of stakeholder groups. This report presents audit statements by PwC regarding Talisman's social responsibility. The report also included an independent opinion regarding the challenge of facing ethical dilemmas in business. tabs., figs.

Salim, Anas Mustafa Ahmed; Hamed, Fatima Hashim Mahmoud

2018-01-01

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

The Domestic Origins of Sudan's External Debt Crisis

Directory of Open Access Journals (Sweden)

Abdel Rahman Ahmed Abdel Rahman

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.

Building a National Heritage Registry for the Sudan: the Friedrich W. Hinkel Archive Digitization Project

Science.gov (United States)

Lawrenz, S.

2017-08-01

The Republic of the Sudan is home to outstanding and diverse cultural heritage ranging from Neolithic sites of human activity and settlement to historic sites of the 19th and 20th century. While certain phases of the Sudan's cultural heritage such as the period of Egyptian influence during the second and first millennium B.C. have been the focus of archaeological research since the 19th century, other aspects of the country's rich history have remained largely unknown locally and internationally due to a lack of documentation and registration of such sites. Since 2014, the German Archaeological Institute (DAI) has been engaged in an effort to support the creation of a national heritage registry in close cooperation with the National Corporation for Antiquities and Museums (NCAM) by digitizing the archive of German architect Friedrich W. Hinkel and engaging in capacity building measures focusing on analog and digital data curation. The archive contains structured information (photos, drawings, maps and assembled written documentation) regarding over 14,000 archaeological and historical sites in the Sudan using an alphanumeric coding system that allows for easy integration of data in a digital environment such as the DAI's IT infrastructure, the iDAI.world. As such the data assembled by Hinkel will serve as the basis of the national heritage registry currently in development.

Yong

2017-01-01

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.

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.

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.

Spatiality of ethnic identity and construction of sociopolitical interaction in South Sudan

Directory of Open Access Journals (Sweden)

Kon K. Madut

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.

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.

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

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.

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

Del Viso, N

1997-01-01

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.

2018-01-15

Sudan I is a carcinogenic industrial azo-dye, forbidden for use in food. However, it has been detected in food on several occasions, such as in paprika, used in animal husbandry to enhance egg yolk colour. Therefore, an animal experiment was designed to simulate the transfer of Sudan I to eggs after its unintentional administration to laying hens. A group of laying hens (n=18) received feed contaminated with Sudan I at the raising concentrations: 0.45mg/kg, 4.97mg/kg and 42.1mg/kg. Residues of Sudan I were detected in egg yolks (0.29±0.03µg/kg, mean±SD) only after the administration of the feed contaminated with the dye at the highest concentration. The determined concentrations were much lower than expected based on the compound's lipophilicity. In conclusion, the transfer of Sudan I to eggs was limited and strongly dependent on its concentration in feed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Sporotrichoid cutaneous leishmaniasis due to Leishmania major of different zymodemes in the Sudan and Saudi Arabia: a comparative study

DEFF Research Database (Denmark)

Gaafar, A; Fadl, A; el Kadaro, A Y

1994-01-01

Sporotrichoid cutaneous leishmaniasis is due to dissemination of amastigotes via the lymphatics to the subcutaneous tissues. A comparison was made between the potential to disseminate by this route of 2 parasites of different zymodemes in Sudan and Saudi Arabia. In Sudan cutaneous leishmaniasis...... is caused by Leishmania major zymodeme LON-1, and in Saudi Arabia by L. major LON-4. Sporotrichoid leishmaniasis was significantly more common in Sudan, occurring in 23% of patients compared with 10% in Saudi Arabia. Lymph node involvement was slightly more prevalent in the Sudan. Clinical and pathological...... differences between subcutaneous nodules, particularly when they ulcerate, and multiple primary cutaneous lesions are described and treatment of localized and sporotrichoid leishmaniasis is discussed. The pathological features of the primary lesions in the Sudan and Saudi Arabia were similar....

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

International Nuclear Information System (INIS)

Awadalla, M.S.; Badawi, A.E.

1980-01-01

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

Khalafalla, A.I.; Awad, S.; Hass, W.

2002-01-01

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.

A cluster of fatal hepatitis cases in northern Cameroon in 1984 stimulated a field investigation to rule out an epidemic of yellow fever. A serosurvey of villages in the extreme north of the country, in a Sudan savanna (SS) phytogeographical zone, disclosed no evidence of recent yellow fever infection. However, further south, in a Guinea savanna (GS) phytogeographical zone, serological evidence was found of endemic yellow fever virus transmission. The results indicate a potential for epidemic...

Assessment of radioactivity in building material(granite) in Sudan

International Nuclear Information System (INIS)

Osman, Z. A; Salih, I; Albadwai, K. A; Salih, A. M; Salih, S. A.

2016-01-01

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)

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

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.

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

Ultra-Sensitive Lab-on-a-Chip Detection of Sudan I in Food using Plasmonics-Enhanced Diatomaceous Thin Film.

Science.gov (United States)

Kong, Xianming; Squire, Kenny; Chong, Xinyuan; Wang, Alan X

2017-09-01

Sudan I is a carcinogenic compound containing an azo group that has been illegally utilized as an adulterant in food products to impart a bright red color to foods. In this paper, we develop a facile lab-on-a-chip device for instant, ultra-sensitive detection of Sudan I from real food samples using plasmonics-enhanced diatomaceous thin film, which can simultaneously perform on-chip separation using thin layer chromatography (TLC) and highly specific sensing using surface-enhanced Raman scattering (SERS) spectroscopy. Diatomite is a kind of nature-created photonic crystal biosilica with periodic pores and was used both as the stationary phase of the TLC plate and photonic crystals to enhance the SERS sensitivity. The on-chip chromatography capability of the TLC plate was verified by isolating Sudan I in a mixture solution containing Rhodamine 6G, while SERS sensing was achieved by spraying gold colloidal nanoparticles into the sensing spot. Such plasmonics-enhanced diatomaceous film can effectively detect Sudan I with more than 10 times improvement of the Raman signal intensity than commercial silica gel TLC plates. We applied this lab-on-a-chip device for real food samples and successfully detected Sudan I in chili sauce and chili oil down to 1 ppm, or 0.5 ng/spot. This on-chip TLC-SERS biosensor based on diatomite biosilica can function as a cost-effective, ultra-sensitive, and reliable technology for screening Sudan I and many other illicit ingredients to enhance food safety.

Preparation of carbon quantum dots from cigarette filters and its application for fluorescence detection of Sudan I.

Science.gov (United States)

Anmei, Su; Qingmei, Zhong; Yuye, Chen; Yilin, Wang

2018-09-06

Carbon quantum dots (CQDs) with quantum yield of 14% were successfully synthesized via a simple, low-cost, and green hydrothermal treatment using cigarette filters as carbon source for the first time. The obtained CQDs showed a strong emission at the wavelength of 465 nm, with an optimum excitation of 365 nm.Sudan I with maximum absorption wavelength at 477 nm could selectively quench the fluorescence of CQDs. Based on this principle, a fluorescence probe was developed for Sudan I determination. Furthermore, the quenching mechanism of the CQDs was elucidated. A linear relationship was found in the range of 2.40-104.0 μmol/L Sudan I with the detection limit (3σ/k) of 0.95 μmol/L. Satisfactory results were achieved when the method was submitted to the determination of Sudan I in food samples. Copyright © 2018 Elsevier B.V. All rights reserved.

The state of emergency care in the Republic of the Sudan

Directory of Open Access Journals (Sweden)

Nada Hassan A. A-Rahman

2014-06-01

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.

Emergency measles control activities--Darfur, Sudan, 2004.

Science.gov (United States)

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.

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 use of radioisotope technology in petrochemical industry in Sudan started in 2003, since then gamma scanning for distillation columns and tracer applications for leak detection was performed 6 times at a refinery 60 Km away from Khartoum, by Sudan Atomic Energy Commission II T group. This paper focuses on safety and radiation protection for this practice, also describes safety requirements, the emergency plan and evaluation of dose worker value which was done on these missions. The assessment of worker's doses performed showed that they are within an acceptable range. Recommendations are made to even bring them lower. The paper also sheds light on some problems raised and suggests remedial actions.(Author)

Container contamination as a possible source of a diarrhoea outbreak in Abou Shouk camp, Darfur province, Sudan.

Science.gov (United States)

Walden, Vivien Margaret; Lamond, Elizabeth-Anne; Field, Sally A

2005-09-01

Diarrhoea is one of the five major causes of death in an emergency setting and one of the three main causes of death in children (Curtis and Cairncross, 2003). In June 2004, an outbreak of shigellosis was confirmed in Abou Shouk camp in the Northern Darfur province of Sudan. As water testing showed no contamination, it was assumed that post-collection contamination was happening. The decision was taken to launch a programme of mass disinfection of all water containers in order to break the contamination cycle. Diarrhoea figures from the clinics showed a fall in cases following the cleaning campaign. It is extremely difficult to obtain good and statistically rigorous data in an emergency setting, the priority being to intervene rapidly to prevent further cases of diarrhoea. However, the results do appear to indicate that the disinfection programme has had an impact on the prevalence of bloody and watery diarrhoea.

CONTROL OF SCHISTOSOMIASIS IN THE GEZIRA IRRIGATION SCHEME, SUDAN.

Science.gov (United States)

Amin, Mutamad; Abubaker, Hwiada

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.

Sudan challenges the sand dragon.

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).

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.

To study the factors influencing happiness of grandmothers raising grandchildren in the rural areas of Northern Thailand. Cross-sectional survey research was conducted among 400 grandmothers, aged 50-79 years, who raised their grandchildren in the rural areas of Northern Thailand. Participants were selected by cluster sampling. Data were collected through a structured interview from April to July 2009 and analyzed by frequency, percentage, Pearson product moment correlation coefficient, and Multiple regression analysis. Nearly half (46.8%) of grandmothers raising grandchildren had high level of happiness, followed by moderate level (40.4%) and low level (12.8%). The factors, which significantly influenced the happiness of the grandmothers, were self-esteem, social support, and family relationships (p-value happiness of the grandmothers by 48.1%. Self-esteem had the highest predictive power of happiness among grandmothers. The factors influencing happiness of grandmothers raising grandchildren were self-esteem, social support, and family relationships. To promote happiness of grandmothers, responsible organizations should establish activities that enhance the grandmother's self-esteem, provide sufficient social support, and promote good family relationships.

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)

2016-01-01

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

Rajabi, Maryam; Sabzalian, Sedigheh; Barfi, Behruz; Arghavani-Beydokhti, Somayeh; Asghari, Alireza

2015-12-18

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.

2010-01-01

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.

2013-10-01

Full Text Available Summary: Introduction: Sudan is subject to repeated outbreaks, including Viral Hemorrhagic Fever (VHF, which is considered to be a very serious illness. Yellow Fever (YF outbreaks in Sudan have been reported from the 1940s through 2005. In 2012, a new outbreak of YF occurred in the Darfur region. Objective: To identify the potential for an outbreak, to diagnose the disease and to be able to recognize its cause among the initial reported cases. Methodology: >This is a descriptive and investigative field study that applies standard communicable disease outbreak investigation steps. The study involved clinical, serological, entomological and environmental surveys. Results: The field investigation confirmed the outbreak and identified its cause to be YF. Conclusion: National surveillance systems should be strong enough to detect VHFs in a timely manner. Local health facilities should be prepared to promptly treat the initial cases because the case fatality ratios (CFRs are usually very high among the index cases.

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

Science.gov (United States)

Lenhardt, Nils; Borah, Suranjana B.; Lenhardt, Sukanya Z.; Bumby, Adam J.; Ibinoof, Montasir A.; Salih, Salih A.

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

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

Science.gov (United States)

Al-Salem, Waleed; Herricks, Jennifer R; Hotez, Peter J

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

Depletion of forest resources in Sudan. Intervention options for optimal control

International Nuclear Information System (INIS)

Hassan, Rashid; Hertzler, Greg; Benhin, James K.A.

2009-01-01

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.

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.

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.

Henry Solomon Wellcome: A philanthropist and a pioneer sponsor of medical research in the Sudan.

Science.gov (United States)

Adeel, Ahmed Awad A

2013-01-01

Henry Solomon Wellcome, the famous drug manufacturer had a fascinating association with the Sudan. Besides supporting tropical medicine research in this country, he established an extensive project in the Sudan that aimed at combining archeological excavations, philanthropy and social reform. This article is an archives-based account on this side of Wellcome's association with the Sudan. The article starts with Wellcome's early years in the American Midwest and the evolution of his career and his rise as a world-renowned drug manufacturer. After the battle of Omdurman, Wellcome visited Sudan in 1900 - 1901 where he offered to support the establishment of the research laboratories which later came to be known as the Wellcome Tropical Research Laboratories in Khartoum. He then became directly involved in the planning and running of extensive archeological excavations in the central Sudan. This project served as a field in which Wellcome found an outlet for his philanthropy. More than 4000 labourers were employed in Jebel Moya. Professional archeologists and anatomists were recruited by Wellcome to supervise the work, and all the requirements in terms of equipment were catered for. Wellcome devised a Savings Bank System whereby part of the earnings of each labourer were saved to him till the end of the season. He also introduced one of his innovations: aerial photography using box kite which was used for the first time in archeology. Wellcome made it a rule that no applicant should be turned away. The Camp Commandant had to find suitable work for each applicant, including the handicapped who were assigned to appropriate jobs like mending baskets or cutting grass for building huts. Wellcome's welfare work had a significant impact on the local inhabitants of Jebel Moya. Henry Solomon Wellcome, 1906. Oil painting by Hugh Goldwin Riviere. Credit: Wellcome Library.

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

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.

Khalid Noteila M

2012-11-01

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

Dispersive liquid-phase microextraction with solidification of floating organic droplet coupled with high-performance liquid chromatography for the determination of Sudan dyes in foodstuffs and water samples.

Science.gov (United States)

Chen, Bo; Huang, Yuming

2014-06-25

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.

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.

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

Wu, Mianmian; Li, Pan; Zhu, Qingxia; Wu, Meiran; Li, Hao; Lu, Feng

2018-05-01

There has been an increasing demand for rapid and sensitive techniques for the identification of Sudan compounds that emerged as the most often illegally added fat-soluble dyes in herbal medicine. In this report, we have designed and fabricated a functionalized filter paper consisting of gold nanorods (GNRs) and mono-6-thio-cyclodextrin (HS-β-CD) as a surface-enhanced Raman spectroscopy (SERS) substrate, in which the GNR provides sufficient SERS enhancement, and the HS-β-CD with strong chemical affinity toward GNR provides the inclusion compound to capture hydrophobic molecules. Moreover, the CD-GNR were uniformly assembled on filter paper cellulose through the electrostatic adsorption and hydrogen bond, so that the CD-GNR paper-based SERS substrate (CD-GNR-paper) demonstrated higher sensitivity for the determination of Sudan III (0.1 μM) and Sudan IV (0.5 μM) than GNRs paper-based SERS substrate (GNR-paper), with high stability after the storage in the open air for 90 days. Importantly, CD-GNR-paper can effectively collect the Sudan dyes from illegally adulterated onto samples of Resina Draconis with a simple operation, further open up new exciting opportunity for SERS detection of more compounds illegally added with high sensitivity and fast signal responses.

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

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.

The role of COMESA in promoting intra-regional agricultural trade: Case study of Sudan

Directory of Open Access Journals (Sweden)

Azharia Abdelbagi Elbushra

2011-06-01

Full Text Available African countries have created many regional trade agreements with the economic objectives of reducing trade barriers and encouraging economic growth. The COMESA is an example of regional integration singed on 1993 by 19 African countries including Sudan. COMESA represents a chance for member countries to enhance their economic and social relations through increasing intra-trade. The objective of this paper is to assess the role of COMESA in promoting intra-regional agricultural trade between Sudan and COMESA countries. A multi-market model with Armington non-linear specification was applied. The paper results showed that there is a great potential for Sudan to increase its agricultural exports to other COMESA countries. The domestic agricultural markets are expected to be hampered by imports surge and increase in competition, while the producers of agricultural export commodities will be better off. In order to compete and benefit from potential in the COMESA markets, the paper recommended improving efficiency in the Sudanese agricultural sector through increasing productivity, lowering cost of production, enhancing marketing services, attaining economies of scale and attracting foreign investment.

Benmassaoud, Yassine; Villaseñor, María J; Salghi, Rachid; Jodeh, Shehdeh; Algarra, Manuel; Zougagh, Mohammed; Ríos, Ángel

2017-05-01

Two methods for the determination of Sudan dyes (Sudan I, Sudan II, Sudan III and Sudan IV) in food samples, by solid phase extraction - capillary liquid chromatography, are proposed. Both methods use nanocellulose (NC) extracted from bleached argan press cake (APC), as a nano-adsorbent recycled from an agricultural waste material. One of the methods involves the dispersion of NC in food sample extracts, along with the waste and eluents being separated by centrifugation. In the other method, NC was modified by magnetic iron nanoparticles before using it in the extraction of Sudan dyes. The use of a magnetic component in the extraction process allows magnetic separation to replace the centrifugation step in a convenient and economical way. The two proposed methods allows the determination of Sudan dye amounts at the 0.25-2.00µgL -1 concentration range. The limit of detections, limit of quantifications and standard deviations achieved were lower than 0.1µgL -1 , 0.20µgL -1 and 3.46% respectively, when using NC as a nano-adsorbent, and lower than 0.07µgL -1 , 0.23µgL -1 and 2.62%, respectively, with the magnetic nanocellulose (MNC) was used. Both methods were applied to the determination of Sudan dyes in barbeque and ketchup sauce samples, obtaining recoveries between 93.4% and 109.6%. Copyright © 2017 Elsevier B.V. All rights reserved.

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.

Transport of radioactive material in Sudan practice and regulations

Abdalla, M. K. E.

2010-12-01

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)

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.

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.

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.

Case-based surveillance measles data was defined according to World Health Organization (WHO) guidelines. A total of 511 measles cases were studied from 2011 to 2015 in Southern Darfur State, Sudan and 58.1% of cases were confirmed from Nyala city. About 43.4% of cases were males, 56.6% of cases were female, and 47.7% were children under five years old. Similarity, within February to June, the cases increased by 8.0% in children vaccinated through measles campaign, and 5.3% in children that used child vaccination card and 78.7% in unvaccinated one. The epidemiologically linked (EPI-Linked) measles cases declined from 2011 to 2015; consequently, Measles still remain to be a significant challenge in south Darfur state, Sudan.

2008-01-01

To set up an immunoassay-based method to detect Sudan dyes and Para red, we generated a monoclonal antibody (Mab) using a specially designed carboxyl derivative of Sudan I (CSD I) as the immunogen. CSD I was synthesized by azocoupling reaction using 2-naphthol and diazotised 4-aminobenzoic acid. The antibody was obtained from a hybridoma, which was derived from the fusion of the mouse myeloma SP2/0 cells and the splenocytes from the mice immunized with the CSD I-bovine serum albumin (BSA) conjugate. In addition, we showed that the Mab was highly specific for Sudan I, III and Para red. The limit of detection was approximately 0.01 ng mL -1 in phosphate-buffered saline (PBS) buffer and 0.5 ng g -1 in chilli tomato sauce. The recoveries of Sudan I, III and Para red for the chilli tomato sauce were from 84% to 99% and coefficients of variation were from 14.9% to 33.3%. Thus, the enzyme-linked immunosorbent assay (ELISA) method is a rapid and high throughput screening tool to detect Sudan dyes and Para red in food products

A cluster of fatal hepatitis cases in northern Cameroon in 1984 stimulated a field investigation to rule out an epidemic of yellow fever. A serosurvey of villages in the extreme north of the country, in a Sudan savanna (SS) phytogeographical zone, disclosed no evidence of recent yellow fever infection. However, further south, in a Guinea savanna (GS) phytogeographical zone, serological evidence was found of endemic yellow fever virus transmission. The results indicate a potential for epidemic spread of yellow fever virus from the southern GS zone to the nothern SS zone of Cameroon, where immunity in the population was low.

Full Text Available A rapid and sensitive method based on ultrafast liquid chromatography–tandem mass spectrometry was developed and validated for simultaneous determination of Sudan I, Sudan II, Sudan III, and Sudan IV levels in rat whole blood. Cleanert C18 mixed-mode polymeric sorbent was used for effective solid-phase extraction cleanup. Separation was carried out on a reversed-phase C18 column (100 mm×2.1 mm, 1.8 μm using 0.1% (v/v formic acid in water/0.1% (v/v formic acid in acetonitrile as the mobile phase in gradient elution. Quantification was performed by an electrospray ionization source in the positive multiple reaction monitoring mode using D5-Sudan I as the internal standard. Calibration curves showed good linearity between 0.2 and 20.0 μg/L, with correlation coefficients higher than 0.9990. The average recovery rates were between 93.05% and 114.98%. The intra- and inter-day relative standard deviations were within 6.2%. The lower limit of quantification was 0.2 μg/L. All the analytes were found to be stable in a series of stability studies. The proposed method was successfully applied to a pharmacokinetic study of four Sudan dyes after oral administration to rats.

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.

2014-01-01

Sudan has been decided to prepare a strategy plan for the first nuclear power plant for various reasons like production electricity and increase the national industries besides the capabilities to do the scientific and research activities. Sudan has been started to establish and develop a master plan for the human resource development and makes a comprehensive realistic assessment about the organizational, educational and industrial capabilities and determines the requirements for developing the quality and quantity of human resources needed. The national nuclear regulatory authority has been started to update all legislation and regulations and also reviews and evaluates the international agreements and conventions related to the nuclear energy. In this profile we used the methodology of the international atomic energy agency to assess and evaluate the capacity building in Sudan. The expected outcomes from this profile are identified the gaps regarding the strengthening the national infrastructure and nuclear regulatory framework and issuing regulations to met the requirements for safety and security of the nuclear power plant. The availability of the human resources skills are important for effectively monitors the activities of the companies and facilities involved in nuclear power plant. The new nuclear law and the new national policy of the nuclear program are now under the process of approval.(author)

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.

Summary of Reports from the Country Representatives: Sudan

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.

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.

Analysis of farmers’ adaptation to weather extremes in West African Sudan Savanna

Directory of Open Access Journals (Sweden)

David Boansi

2017-06-01

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.

Full Text Available Access to financial service has become a key phenomenon for economic development and poverty alleviation .Microfinance is one way of fighting poverty in Sudan, where most citizens are in need of it. However, despite the initial results showing a positive impact of microfinance on the livelihood of low-income people in Sudan, around 8 million of the Sudanese poor people are excluded from microfinance services. One potential remedy for the limited outreach of microfinance in Sudan may lie within enhancing the capacity of microfinance services providers (MFPs in the utilization of modern technology. Recent innovation in providing financial services in a convenient and efficient way is the use of mobile banking (m-banking technology in microfinance. M-banking promises to increase the efficiency and outreach of microfinance services in developing countries. This paper tries to examine the factors that influence the adoption of m-banking by microfinance sector in Sudan. In this respect, hypotheses were developed guided by Unified Theory of Acceptance and Use of Technology (UTAUT and Technology-organization-Environment (TOE models. Primary data were collected from MFPs and microfinance customers in Sudan using questionnaires and interviews. The study contributes to knowledge in terms of methods used by extending aforementioned theories through adding new variables to both models by putting both models in one study to fill the gaps in past studies; via examination of the demand (customers and supply (institutions through modifying them to include new variables related to m-banking in microfinance.

As a result of armed civil conflict in South Sudan that started in mid-December of 2013, an estimated 1.1 million persons were internally displaced, and approximately 400,000 refugees fled South Sudan to neighboring countries (primarily to Ethiopia, Uganda, Sudan, and Kenya). Refugees from South Sudan arriving in Ethiopia are sheltered in three refugee camps located in Gambella region: Leitchuor, Kule, and Tierkidi. The camps were established during January-May 2014 and have estimated refugee populations of 47,000, 51,000, and 50,000, respectively. Reports from health clinics and humanitarian agencies providing assistance to refugees suggested poor nutritional status of arriving refugees and elevated mortality rates. To assess the nutritional status of refugee children aged 6-59 months and mortality rates (crude [all ages] and aged <5 years), the Administration for Refugee and Returnee Affairs (an Ethiopian government aid agency), the United Nations High Commissioner for Refugees, World Food Programme, and United Nations Children's Fund, in collaboration with CDC, conducted cross-sectional population-representative surveys in Leitchuor, Kule, and Tierkidi camps during June-July 2014. Anthropometric measurements in children were taken using standard procedures, and nutritional status was classified based on 2006 World Health Organization (WHO) growth standards. Hemoglobin was measured using HemoCue Hb 301. Anemia was diagnosed according to WHO thresholds. Retrospective mortality rates in Leitchuor and Kule were measured using a household census method.

This work describes the mutagenic response of Sudan III, an adulterant food dye, using Salmonella typhimurium assay and the generation of hazardous aromatic amines after different oxidation methods of this azo dye. For that, we used metabolic activation by S9, catalytic oxidation by ironporphyrin and electrochemistry oxidation in order to simulate endogenous oxidation conditions. The oxidation reactions promoted discoloration from 65% to 95% of Sudan III at 1 × 10(-4)molL(-1) and generation of 7.6 × 10(-7)molL(-1) to 0.31 × 10(-4)molL(-1) of aniline, o-anisidine, 2-methoxi-5-methylaniline, 4-aminobiphenyl, 4,4'-oxydianiline; 4,4'-diaminodiphenylmethane and 2,6-dimethylaniline. The results were confirmed by LC-MS-MS experiments. We also correlate the mutagenic effects of Sudan III using S. typhimurium with the strain TA1535 in the presence of exogenous metabolic activation (S9) with the metabolization products of this compound. Our findings clearly indicate that aromatic amines are formed due to oxidative reactions that can be promoted by hepatic cells, after the ingestion of Sudan III. Considering that, the use of azo compounds as food dyestuffs should be carefully controlled. Copyright © 2013 Elsevier Ltd. All rights reserved.

2012-11-01

To identify and understand knowledge and practice among traditional birth attendants (TBAs), a total of 111 TBAs were interviewed at Kassala, Eastern Sudan between March and April 2011. Hand-washing prior to the delivery was a universal practice but only 25.2% of the interviewed TBAs used sterilised equipment. TBAs in this study appeared to have a low level of awareness about when a mother should be referred to hospital, and lacked basic information on family planning and HIV/AIDS. None of these 111 TBAs knew or used equipment for neonatal resuscitation (such as bag, tube and mask) or knew neonatal signs that needed extra attention such as change in skin colour, weak suckling and respiratory distress, and nearly one-third (28.8%) of the respondents believed in a few days delay in milk production. Thus, substantial effort is needed to improve the knowledge and practice among TBAs in Eastern Sudan, including training programmes, and this might be the best hope to achieve the Millennium Development Goals.

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)

Trachoma and women: latrines in Ethiopia and surgery in Southern Sudan

Directory of Open Access Journals (Sweden)

Paul M Emerson

2009-06-01

Full Text Available Although there may be an underlying biological reason that more women are affected by trachoma and trichiasis, the role of women as childcare providers is a likely cause. In most countries where trachoma is endemic, girls grow up in environments where one of their primary activities is taking care of their younger family members and siblings. This continues into adulthood, with women carrying the main responsibility of caring for children. During their lifetime, women therefore spend more time in direct contact with children who may be infected. Ethiopia and Southern Sudan are two locations with an exceedingly high burden of trachoma. Projects focusing on environmental improvement (in Ethiopia and increasing access to surgery (in Southern Sudan have made significant progress towards reducing the impact of the disease on women. These examples show how trachoma programmes can address the particular needs of women while designing interventions aimed at eliminating blinding trachoma in the community as a whole.

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.

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 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

Measurements of uranium and thorium isotopes, 226 Ra, 210 Po, 228 Ra, 40 K and fallout radionuclide 137 Cs in soil samples collected from different districts in Sudan, rock phosphate samples collected from the uro and kurun rock phosphate deposits in the eastern part of the Nuba mountains in Western Sudan, and surface marine sediments and marine organisms collected from the sudanese coastal waters of the Red Sea have been made using a high resolution gamma-spectrometry, radiochemical separation and α spectrometry. The external exposure due to γ radiation from the ground has been calculated. The average exposure was found to be 45.4 ± 21.3 nGy/h, corresponding to the annual dose equivalent of 278 μSv/y. With the exception of some areas, the calculated exposure falls within the global wide range of outdoor radiation exposure given in the UNSCEAR publications. The nation-wide average concentrations of 226 Ra, 238 U, 232 Th, 40 K and 137 Cs determined were 31.6 ± 27, 20.1 ± 16.4, 19.1 ± 8.1, 280.3 ± 137.6 and 4.1 ± 4.3 Bq/Kg, respectively. This shows that there is little contamination due to fallout radioactivity at survey sites. The exchangeable radium fraction constitutes 19-24% of the total radium content. The data show that 238 U and its decay products are the principal contributors of radioactivity in both phosphate deposits at Uro and Kurun. The equivalent mass concentrations of uranium in the Uro rock phosphate fall within the range that could be economically recovered as the by-product of fertilizer industry. The mean activity concentrations weighted by average agricultural consumption of 300 kg/ha of untreated ground rock fertilizer resulted in an annual distribution of 120.63 Bq Ra/m 2 with Uro rock and 12.97, 0.21 and 4.24 Bq/m 2 respectively, with Kurun rock fertilizer. The external radiation exposure over agricultural areas was estimated 23.41 x 10 -9 Gy/h and 2.59 x 10 -9 Gy/h at 1 m above ground level for Uro and Kurun rock phosphate fertilizers

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

The recent droughts in Western Ethiopia and Sudan in a climatic context

Energy Technology Data Exchange (ETDEWEB)

Mattsson, J.O.; Rapp, A. (University of Lund, Lund (Sweden). Dept. of Physical Geography)

1991-08-01

Examined here are two recent episodes of drought that occurred in western Ethiopia, Sudan and elsewhere in the Sahelian zone immediately south of the Sahara during the periods 1968-1973 and 1979-1984. These are shown to have followed a series of similar episodes during the earlier decades of the 1900s. Another disaster of drought, war and famine struck western Ethiopia and Sudan in 1990-1991. The zone has been arid for the past 4000 years at least. The dryland degradation associated with episodes of drought is considered to result from a combination of climatic and human impact factors. It is suggested that recently elucidated correlations between the Sahelian drought episodes and oceanic temperatures and circulation lead to the possibility of developing a predictive system for Sahelian droughts. However, to establish a functional early-warning system will require a sustained trans-disciplinary research and development effort of some magnitude.

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

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

Science.gov (United States)

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.

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. 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). 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. 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.

Magnetic solid-phase extraction is an effective and useful technique to preconcentrate trace analytes from food samples. In this study, a magnetic trimeric chromium octahedral metal-organic framework (Fe 3 O 4 -NH 2 @MIL-101) was fabricated and characterized. Fe 3 O 4 -NH 2 @MIL-101 was applied as an adsorbent of magnetic solid-phase extraction combined with high performance liquid chromatography to effectively isolate and simultaneously determine six Sudan dyes (Para Red, Sudan I-IV, and Sudan Red 7B) from tomato sauce. Potential factors affecting the MSPE were investigated in detail, and adsorption efficiency of Fe 3 O 4 -NH 2 @MIL-101 was compared with those of conventional adsorbents, such as neutral alumina, HLB, and C 18 . The developed method facilitated the extraction with using only 3 mg of adsorbent in 2 min. In addition, enhancement factors of 50, linear range of 0.01-25 μg/mL, and detection limit (S/N = 3) of 0.5-2.5 μg/kg were obtained. The intra-day and inter-day recoveries for spiked Sudan dyes were in the range of 72.6%-92.9% and 69.6%-91.6%, respectively, with relative standard deviations of ≤9.2%. Copyright © 2018 Elsevier B.V.

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.

2009-01-01

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)

'That thing of human rights': discourse, emergency assistance, and sexual violence in South Sudan's current civil war.

Science.gov (United States)

Luedke, Alicia Elaine; Logan, Hannah Faye

2018-01-01

One of the most widely covered aspects of the current conflict in South Sudan has been the use sexual violence by rival factions of the Sudan People's Liberation Movement/Army (SPLM/A) and other armed groups. While this has had the positive effect of ensuring that sexual violence is an integral component of intervention strategies in the country, it has also had a number of unintended consequences. This paper demonstrates how the narrow focus on sexual violence as a 'weapon of war', and the broader emergency lens through which the plight of civilians, especially women, has been viewed, are overly simplistic, often neglecting the root causes of such violence. More specifically, it highlights how dominant discourses on sexual violence in South Sudan's conflict have disregarded the historically violent civil-military relations that have typified the SPLM/A's leadership, and the structural violence connected with the local political economy of bride wealth and the associated commodification of feminine identities and bodies. © 2018 The Author(s).

Peste des petits ruminants (PPR) is an acute viral disease of small ruminants. The disease was first reported in Tanzania in 2008 when it was confined to the Northern Zone districts bordering Kenya. The present study was carried out to confirm the presence of PPR virus (PPRV) in Tanzania and to establish their phylogenetic relationships. Samples (oculonasal swabs, tissues and whole blood) were obtained from live goats with clinical presentation suggestive of PPR and goats that died naturally in Ngorongoro (Northern Tanzania) and Mvomero (Eastern Tanzania) districts. The clinical signs observed in goats suspected with PPR included fever, dullness, diarrhea, lacrimation, matting of eye lids, purulent oculonasal discharges, cutaneous nodules, erosions on the soft palate and gums and labored breathing. Post mortem findings included pneumonia, congestion of the intestines, and hemorrhages in lymph nodes associated with the respiratory and gastrointestinal systems. PPRV was detected in 21 out of 71 tested animals using primers targeting the nucleoprotein (N) gene. Phylogenetic analysis, based on the N gene, indicated that PPRV obtained from Northern and Eastern Tanzania clustered with PPRV strains of Lineage III, together with PPRV from Sudan and Ethiopia. The findings of this study indicate that there are active PPRV infections in Northern and Eastern Tanzania, suggesting risks for potential spread of PPR in the rest of Tanzania. © 2014 The Authors.

Nodding syndrome (NS) and Onchocerca Volvulus (OV) in Northern Uganda.

Science.gov (United States)

Lagoro, David Kitara; Arony, Denis Anywar

2017-01-01

Nodding Syndrome (NS) is a childhood neurological disorder characterized by atonic seizures, cognitive decline, school dropout, muscle weakness, thermal dysfunction, wasting and stunted growth. There are recent published information suggesting associations between Nodding Syndrome (NS) with cerebrospinal fluid (CSF) VGKC antibodies and serum leiomidin-1 antibody cross reacting with Onchocerca Volvulus ( OV ). These findings suggest a neuro-inflammatory cause of NS and they are important findings in the search for the cause of Nodding Syndrome. These observations perhaps provide further, the unique explanation for the association between Nodding Syndrome and Onchocerca Volvulus . Many clinical and epidemiological studies had shown a significant correlation between NS and infestation with a nematode, Onchocerca volvulus which causes a disease, Onchocerciasis , some of which when left untreated can develop visual defect ("River Blindness"). While these studies conducted in Northern Uganda and Southern Sudan indicate a statistically significant association with ( OV infection (using positive skin snips), we observe that ( OV is generally endemic in many parts of Sub Saharan Africa and Latin America and that to date, no NS cases have been recorded in those regions. This letter to the Editor is to provide additional information on the current view about the relationship between Nodding Syndrome and Onchocerca Volvulus as seen in Northern Uganda.

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.

Pharmaceutical representatives are an important promotional tool for pharmaceutical companies. This cross-sectional, exploratory study aimed to determine pharmaceutical representatives' beliefs and practices about their professional practice in Sudan. A random sample of 160 pharmaceutical representatives were interviewed using a pretested questionnaire. The majority were male (84.4%) and had received training in professional sales skills (86.3%) and about the products being promoted (82.5%). Only 65.6% agreed that they provided full and balanced information about products. Not providing balanced information was attributed by 23.1% to doctors' lack of time. However, 28.1% confessed they sometimes felt like hiding unfavourable information, 21.9% were sometimes or always inclined to give untrue information to make sales and 66.9% considered free gifts as ethically acceptable. More attention is needed to dissemination of ethical codes of conduct and training about the ethics of drug promotion for pharmaceutical representatives in Sudan.

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

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.

Lung cancer is a major cause of cancer death worldwide. The aims of this study were to analyze presentation, treatment and survival for lung cancer in northern Italy, and identify factors influencing survival. A total of 1180 lung cancer cases diagnosed in four north Italian cancer registries (Biella, Modena, Reggio Emilia, Romagna) in 2003-2005 were analyzed. Information on morphology, stage, diagnostic examinations, chemotherapy, radiotherapy, and surgical treatment was collected from clinical records. Three-year relative survival and relative excess risks of death were estimated. Overall, 10% of cases were stage I, 50% stage IV, and 12% stage unknown. Romagna - where sophisticated diagnostic examinations were performed more often - had proportionately more microscopically verified cases and resected cases than Biella. Romagna had also high proportions of cases given chemotherapy and radiotherapy. Three-year survival was 14%, range 10% (Biella) to 19% (Romagna); 69% for stage I, 3% for stage IV. Stage I survival was higher in Romagna (82%) than Reggio Emilia and Biella (60-61%) but for operated stage I cases, survival was similar (88%) in Romagna and Biella. The fully adjusted model showed a higher risk of death in Biella (1.23, 95%CI 1.02-1.48) than Modena (reference). Stage and surgery are key factors influencing survival. Centralizing lung cancer treatment to improve diagnostic work-up may improve outcomes. Copyright © 2013 Elsevier Ltd. All rights reserved.

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.

Effect of desertification and soil salinity on land productivity in the Sudan

International Nuclear Information System (INIS)

El-Karouri, M.O.H.

1980-01-01

Although the Sudan contains one of the largest reserves of cultivable and irrigable land in the world, desertification and salinization have had a severe effect on soil productivity. Irrational cultivation of marginal lands and the abuse of tractor power have led to severe erosion problems. Deforestation, overgrazing and the use of fire in land clearing have destroyed natural vegetation. Desertification has claimed most of the land between latitudes 15 0 and 17 0 N and continues to move rapidly. The wild life habitants has been drastically altered with many species becoming extinct. Conflicts have arisen between nomads and cultivators. The government has thus developed a six year programme with emphasis on range seeding, afforestation, water conservation, fire control, sand dune stabilization and shelter belt development. Soil salinity and sodicity present both chemical and physical soil problems especially in irrigated regions. Since the Sudan is increasing its irrigated area from 2 to 4 million ha the problems will increase. Gypsum has not been effective in reclaimation but cultural practices such as ridge planting, timely seeding, and crop selection have shown promise. (author)

Prolonged conflict in South Sudan exacerbated gender disparities and inequities. This study assessed differences in attitudes towards gender inequitable norms and practices by sex, age and education to inform programming. Applying community-based participatory research methodology, 680 adult respondents, selected by quota sampling, were interviewed in seven South Sudanese communities from 2009 to 2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age and education. Of 680 respondents, 352 were female, 326 were male and two did not report their sex. The majority of respondents agreed with gender inequitable household roles, but the majority disagreed with gender inequitable practices (i.e., early marriage, forced marriage and inequitable education of girls). Respondents who reported no education were more likely than those who reported any education to agree with gender inequitable practices (all p gender inequitable norms in the household but an overall disagreement with gender inequitable practices in sampled communities. The findings support that education of both women and men may promote gender equitable norms and practices.

Full Text Available Abstract Background Since 1900s, visceral leishmaniasis (VL has been among the most important health problems in Sudan, particularly in the endemic areas such as eastern and central regions. Methods This was a cross sectional, hospital-based study conducted from 1st January 2015 to 31st December 2015 to investigate the epidemiological factors of VL in Gadarif hospital, eastern Sudan. Results During the study period there were 47 identified children with VL among 145 suspected cases. The most common clinical presentations were fever (47, 100%, pallor (47, 100%, weight loss (40, 85.1%, splenomegaly (37, 78.7%, lymphadenopathy (33, 70.2%, vomiting (32, 68% cough (28, 59%, loss of appetite (22, 46.8%, diarrhoea (17, 36.1% and jaundice (5, 10.6%. With regard to the outcome after short term follow up 37 patients (78.8% improved without complications, while 3 (6.4%, 2 (4.3%, 2 (4.3%, 1 (2.1%, 1 (2.1% and 1 (2.1% developed pneumonia, otitis media, septicaemia, urinary tract infection, parasitic infestation and PKDL respectively. Lower mean of haemoglobin level was observed among the VL cases in comparison with the suspected cases (in whom VL was excluded haemoglobin level {8.9 (3.1 Vs 11 (6.3, P = 0.021}. Again more proportion of anaemic (47 (100% Vs 14 (14.2%, P = 0.000 and severely anaemic (23 (48.9% Vs 2 (2%, P = 0.006 patients was detected among the infected children. Using logistic regression analyses there was significant association between rural residence (CI = 1.5–24, OR = 19.1, P = 0.023, male gender (CI = 6.6–18.7, OR = 6.4, P = 0.001 and VL among children. Conclusions While there is an advance in prevention and management of visceral leishmaniasis our results indicate that VL is still a public health problem with its severe complications among children in eastern Sudan.

Full Text Available Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermonthica population. In the laboratory, 27 varieties were screened for post-attachment resistance using the rhizotron technique. Varieties displaying high post-attachment resistance, Umgar, NERICA5, and NERICA13 together with NERICA4, NERICA18, and Nipponbare, a lowland rice variety, were further evaluated for performance and Striga resistance in pot and semi-controlled open air experiments and for germination inducing activity in a laboratory. In addition, comparative studies on reaction of Umgar, Kosti1 and Kosti2, released varieties for commercial production in Sudan, to the parasite were performed in two pot experiments. In the pot experiments Umgar and NERICA5, consistently, sustained the lowest Striga emergence (< 2.2 Striga plants per pot, while NERICA13 and NERICA4 supported 1.8–5.7 and 8.7–16.4 Striga plants per pot, respectively. In an artificially Striga-infested field, number of emergent Striga plants per 10 rice hills, at harvest, was 2.0, 2.0, 4.8, 13.5, 13.3, and 18.3 on Umgar, NERICA5, NERICA13, NERICA4, NERICA18, and Nipponbare, respectively. Striga had no adverse effects on total above-ground parts and panicle dry weight (DW in Umgar and NERICA5. Germination-inducing activity of root exudates, at 14 days after sowing onwards, was markedly lower for Umgar than for NERICA5, NERICA13, NERICA4, and NERICA18. Based on these findings, Umgar has both pre and post-attachment resistance to a resident Striga population in Sudan. Kosti1 and Kosti2, did not exhibit Striga-resistance at the same level as Umgar. Further the resistance of NERICA5, a

The unprecedented 2014-2015 Ebola virus disease (EVD) outbreak in West Africa has highlighted the need for effective therapeutics against filoviruses. Monoclonal antibody (MAb) cocktails have shown great potential as EVD therapeutics; however, the existing protective MAbs are virus species specific. Here we report the development of pan-ebolavirus and pan-filovirus antibodies generated by repeated immunization of mice with filovirus glycoproteins engineered to drive the B cell responses toward conserved epitopes. Multiple pan-ebolavirus antibodies were identified that react to the Ebola, Sudan, Bundibugyo, and Reston viruses. A pan-filovirus antibody that was reactive to the receptor binding regions of all filovirus glycoproteins was also identified. Significant postexposure efficacy of several MAbs, including a novel antibody cocktail, was demonstrated. For the first time, we report cross-neutralization and in vivo protection against two highly divergent filovirus species, i.e., Ebola virus and Sudan virus, with a single antibody. Competition studies indicate that this antibody targets a previously unrecognized conserved neutralizing epitope that involves the glycan cap. Mechanistic studies indicated that, besides neutralization, innate immune cell effector functions may play a role in the antiviral activity of the antibodies. Our findings further suggest critical novel epitopes that can be utilized to design effective cocktails for broad protection against multiple filovirus species. Filoviruses represent a major public health threat in Africa and an emerging global concern. Largely driven by the U.S. biodefense funding programs and reinforced by the 2014 outbreaks, current immunotherapeutics are primarily focused on a single filovirus species called Ebola virus (EBOV) (formerly Zaire Ebola virus). However, other filoviruses including Sudan, Bundibugyo, and Marburg viruses have caused human outbreaks with mortality rates as high as 90%. Thus, cross

The Carboniferous Lisburne Group is a major carbonate reservoir unit in northern Alaska. The lisburne is detachment folded where it is exposed throughout the northeastern Brooks Range, but is relatively underformed in areas of current production in the subsurface of the North Slope. The objectives of this study are to develop a better understanding of four major aspects of the Lisburne: (1) The geometry and kinematics of detachment folds and their truncation by thrust faults, (2) The influence of folding on fracture patterns, (3) The influence of deformation on fluid flow, and (4) Lithostratigraphy and its influence on folding, faulting, fracturing, and reservoir characteristics.

Summary: Herein, a novel electrochemical method was de veloped for the determination of Sudan II based on the electrochemical catalytic activity of graphene modified glassy carbon electrode (GME) and the enhancement effect of sodium dodecyl sulfate (SDS). In a pH 6.0 phosphate buffer solution, Sudan II exhibited a pair of well-defined quasi reversible redox peaks at the GME in the presence of 5.0x10/sup -5/ mol L/sup 1/ SDS. The oxidation peak current of Sudan II was linearly proportional to its concentration in a range from 4.0x10/sup -8/ to 4.0x10/sup -6/ mol L/sup 1/, with a linear regression equation of ipa (A) = 3.35 c + 5.96 x 10/sup -6/, r = 0.9988 and a detection limit of 8.0x10/sup -9/ mol L/sup 1/. The recoveries from the standards fortified blank samples were in the range of 94.7% to 97.5% with RSD lower than 4.0%. The novel method has been successfully used to determine Sudan II in food products with satisfactory results. (author)

The Fragility of the Liberal Peace Export to South Sudan: Formal Education Access as a Basis of a Liberal Peace Project

Directory of Open Access Journals (Sweden)

Ngambouk Vitalis Pemunta

2014-01-01

Full Text Available This study examines the disjuncture between the policy transposition of the Liberal Peace Project (LPP in South Sudan from the country's local context. It underlines how deep rooted historical exclusion from social welfare services reinforces political exclusion and exacerbates poor civic engagement among different ethnicities in the country causing a constant relapse to violence. The study combines a qualitative review of data from Afrobarometer, the National Democratic Institute, international NGOs, and South Sudan's government reports within depth interviews and participants' observation. The research finds that restricted access to formal education alongside the conservative and orthodox approaches to peacebuilding, which broadly focus on centralised urban political institutions and exclude diverse local needs and preferences, limit citizenship participation to elections and preclude an equitable social order in South Sudan, establishing a continuum of fragile authoritarian peace, institutional peace and constitutional peace. In an emancipatory approach, the study proposes a framework that prioritizes an extended access to primary and post-primary vocational education as a more credible establishment for sustainable civil peace in the country. The LPP by the international community needs to be tailored to enhance the political will of the South Sudan government to extend free primary education access, incentivize primary education with school feeding programmes and to invigorate vocational training curricula. These will yield civil peace dividends, which avert South Sudan's structural source of relapse into violence with sustainable disincentives. Apart from women's empowerment through education and in all spheres of life, the government needs to ensure sustainability by guaranteeing a sustainable future for the present and for returning refugees by reducing the effects of climate change so as to cope with the increasing pressure on natural

This research represents taxonomical, anatomical, and chemotaxonomical studies of mosses of Jebel Marra, Darfour State, Sudan. This study and for the first time includes the bryoflora checklist of the Sudan which is gathered from many previous studies, in addition to the present study. The fully identified mosses for the study area are 12 species belonging to 8 different families and 10 different genera. Three genera from the family Bottiaceae, 2 from the family Bartramiaceae,2 from Funariaceae, and one genus recorded for each of the families: Ditrichaceae, Bryaceae,Thuidiaceae and Polytrichaceae. Key to the studied genera is constructed and full species description and illustrations of the most taxonomically important characters are included. In this study the genus Ceratodon Brid. Is recorded for the first time in Sudan, and to the specific level, 5 species are encountered for the time: Barbula Ehenbergii, Philonotis tenuis, Philonotis longiseta, Ceratodon Purpureus, and Thuidium furfurosum. For each species determination of the levels of the heavy metal: sodium, potassium, zinc, cobalt, copper, manganese and iron are studied, in addition to nitrogen and chlorophyll content. ( Author)

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

["Palimpsest scar" lesions in a context of torture (Darfur, Sudan)].

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.

Little is known about the experiences of displaced individuals en route to destination countries. We investigated the reported prevalence of exposure to traumatic experiences during migration among a consecutive sample of adult asylum seekers (n = 895 Eritrean, n = 149 Sudanese) who sought health services in the Physicians for Human Rights Open-Clinic in Israel. Percentage of Eritrean and Sudanese men and women who reported witnessing violence (Eritrea: men: 41.3 %, women: 29.3 %; Sudan: men: 16.8 %, women: 22.2 %) and/or being a victim of violence (Eritrea: men: 56.0 %, Women: 34.9 %; Sudan: men: 51.9 % women: 44.4 %) during migration varied by gender and country of origin. Findings highlight the need for a well-coordinated international cooperation to document and prevent these transgressions.

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

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

Sudan is subject to repeated outbreaks, including Viral Hemorrhagic Fever (VHF), which is considered to be a very serious illness. Yellow Fever (YF) outbreaks in Sudan have been reported from the 1940s through 2005. In 2012, a new outbreak of YF occurred in the Darfur region. To identify the potential for an outbreak, to diagnose the disease and to be able to recognize its cause among the initial reported cases. >This is a descriptive and investigative field study that applies standard communicable disease outbreak investigation steps. The study involved clinical, serological, entomological and environmental surveys. The field investigation confirmed the outbreak and identified its cause to be YF. National surveillance systems should be strong enough to detect VHFs in a timely manner. Local health facilities should be prepared to promptly treat the initial cases because the case fatality ratios (CFRs) are usually very high among the index cases.

Haridi, A A; el Safi, S H; Jobin, W R

1985-04-01

The ampullarid snail Marisa cornuarietis was imported to the Sudan in 1981 for evaluation as a biological control agent against the planorbid snails which transmit human schistosomes. In initial field studies in small protected ponds the generation time of M. cornuarietis was 4 months, as in Puerto Rico. The snails reached 4 cm in diameter after 1 year, compared to 3 cm in Puerto Rico. Their population density varied from 60 to 175 snails per metre of shore-line, compared to a similar pond in Puerto Rico where the stable density was about 115 snails per metre. The proportion surviving after 1 year was 0.03, less than the annual proportion surviving of 0.10 in Puerto Rico. Thus the preliminary results indicated that the ampullarid snails could establish strong populations in permanent habitats in central Sudan where there was adequate food, although it might take longer than it does in Puerto Rico.

Full Text Available Drug promotion by medical representatives is one of the factors that influence physicians' prescribing decisions and choice of drugs.To assess the influence of medical representatives on prescribing practice of physicians in health facilities, Mekelle, Northern Ethiopia.Facility-based cross-sectional study was conducted enrolling all physicians working in public and private health facilities. All public and private health facilities were included and similarly, all physicians rendering services in these facilities were sampled in the study. The data were collected from February to March, 2015. Data were then entered into Epidata Version 3.1 and transferred to STATA version 12 for analysis. Both bivariable and multivariable logistic regressions were used to determine predictors.Of the ninety physicians approached in this study, 40 (48.2% of the physicians believed that their prescribing decisions were influenced by visits of medical representatives (MRs. The odds of physicians who received gifts from MRs being influenced to prescribe their respective products was six times higher than those who reported not accepting any gifts [AOR = 6.56, 95% CI: 2.25, 19.13]. Stationery materials 23(35.4% and drug samples 20(54.2% were the commonest kinds of gifts given to physicians and face to face talking 45(54.2% was the most frequent promotional methods. The finding of this study showed that around thirty-nine percent of MRs have had negative attitude toward competitors' product. Moreover, working in private health facility was also another predictor of influence of prescribing decision in the study area [AOR = 12.78, 95% CI: 1.31, 124.56].Nearly half of the physicians working in Mekelle reported that their prescribing decisions were influenced by MRs in the last 12 months. Accepting gifts and working in private health facilities were predictors of influencing prescribing decisions. However, most MRs fails to provide adequate and accurate information

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.

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.

2012-02-01

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.

Eighty-four stray dogs shot as a part of a governmental rabies control program in two neighboring towns of central Sudan were examined for the presence of Echinococcus spp. and other intestinal helminths. Echinococcus worms were identified to species level by PCR and gene sequencing. For comparative reasons, rectal content of the necropsied dogs was examined for helminth eggs and subjected to copro-PCR for Echinococcus. At necropsy, 51.2% (43/84) of the dogs harbored Echinococcus canadensis (G6/7) worms with worm burdens ranging from 22,000 to 80,000. Dipylidiun caninum was found in 53.6% of the dogs. At coproscopy, taeniid eggs were found in 37 of the 43 dogs which were positive for Echinococcus at necropsy, but none in the 41 necropsy-negative dogs. In addition, 58% of the rectal samples contained eggs of Toxocara spp., 34.5% eggs of Trichuris spp. (34.5%), and 26% eggs of Ancylostoma caninum. Copro-PCR gave positive results for E. canadensis with 97.5% (39/40) of nonhibiting samples from the necropsy positive dogs; the one remaining dog tested positive for E. granulosus sensu stricto (G1), whose partial cox1 and nad1 sequences showed a 100% identity with various reference sequences of the G1 genotype. 100% of 38 non-inhibited samples taken from the necropsy-negative dogs were also negative in copro-PCR. This is the first study which combines prevalence and genetic identification of Echinococcus spp. in dogs of Sudan. Together with a recent report from cattle, it confirms the autochthonous presence, at low level, of E. granulosus sensu stricto in Central Sudan.

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.

Fathelrahman M. Hassan

2012-06-01

Full Text Available Sixty nine per cent of people with hemophilia symptoms in rural areas were accessed to laboratory diagnosis and care support in Sudan, where technical expertise and health care facilities was less than optimal. There were many reasons for the inadequate care of hemophilic patients: the perception of rarity of the disease; lacked of laboratory facilities to diagnose the disorder; lacked of understanding of the disorder by patients, their relatives, and even healthcare providers; poorly developed blood bank facilities; and lacked of adequate factor supply were just some examples. The Sudanese Hemophilia Care Association (SHCA was attempted to address many of these issues by establishing hemophilia care programs and by educating and training healthcare practitioners so that a healthcare team could be organized that attempts to ameliorate these problems and provides treatment options. However, it was possible to manage hemophiliac’s patients with limited resources. Strategies for conserving factor concentrates were included education of doctors and patients, prenatal diagnosis, increasing the use of anti fibrinolytic agents, physiotherapy, the use of fibrin glue, and simple orthotics and prosthetic measures. An outreach program would be initiated to ensure that hemophilia care and diagnosis was available outside the capital city. Official recognition of hemophilia laboratory diagnosis and treatment centers and designated centers by the government could also be very beneficial in ensuring adequate care in rural areas in Sudan.

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

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.

Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05). Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

Nodding Syndrome (NS), previously called Nodding Disease, is a chronic and debilitating illness affecting thousands of children aged 3-18 years in post-conflict Northern Uganda and South Sudan. Characterised by malnutrition, stunted growth, mental retardation and seizures, some researchers have designated it as epilepsy. With reports appearing in Northern Uganda in1997, NS reached epidemic proportions around 2000-2003 when people were moved into Internally Displaced People's (IDP) camps. Investigations for infections (onchocerciasis) and toxins have been inconclusive as to cause, treatment or outcome. No study has addressed the possible relationship of NS to childhood war-trauma experiences. To explore a possible relationship of exposure to prolonged war-trauma and the emergence of epidemic NS in Northern Uganda. This study was a case-series descriptive psychiatric naturalistic field observations of NS cases from homesteads in Northern Uganda and psychiatric investigations and treatment of NS cases referred to Mulago National Referral and Teaching Hospital. Detailed Psychiatric clinical evaluations and field observations revealed that NS children had been exposed to severe war-related psychological and physical trauma as well as non-specific CNS insults including untreated CNS infections/infestations and malnutrition possibly causing seizures. Many children suffered post-traumatic stress disorder (PTSD) and depression. NS could present as an association of childhood complex PTSD, (called Developmental Trauma Disorder), occurring in the chronically war-traumatised children of Northern Uganda, complicated by severe prolonged depression with its characteristic symptoms of psychomotor retardation, anxiety, anhedonia and anorexia. This, coupled with food shortages, resulted in malnutrition, wasting and stunted growth with severe avitaminoses. Many children had seizures. All this calls for multi-disciplinary treatment approaches.

Calculations of the external exposure due to γ radiation from the ground have been made from the results of the measurements of radionuclide activity concentrations in the soil at various locations in Sudan. The average exposure was found to be 45 nGy.h -1 , corresponding to the annual dose equivalent of 278 μSv.y -1 . With the exception of the Arkuri and Dumper areas in the western part of the country, the calculated exposure falls within the global wide range of outdoor radiation exposure given in the UNSCEAR publications. The nationwide average concentrations of 226 Ra, 238 U, 232 Th, 40 K and 137 Cs determined were 31.62, 20.11, 19.10, 280.29 and 4.12 Bq.kg -1 , respectively. This shows that there is little contamination due to fallout radioactivity at survey sites. (author)

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

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.

What will happen if we do nothing to control trachoma: health expectancies for blinding trachoma in southern Sudan.

Full Text Available Uncontrolled trachoma is a leading cause of blindness. Current global trachoma burden summary measures are presented as disability adjusted life years but have limitations due to inconsistent methods and inadequate population-based data on trachomatous low vision and blindness. We aimed to describe more completely the burden of blinding trachoma in Southern Sudan using health expectancies.Age and gender specific trachomatous trichiasis (TT prevalence was estimated from 11 districts in Southern Sudan. The distribution of visual acuity (VA in persons with TT was recorded in one district. Sudan life tables, TT prevalence, and VA were used to calculate Trichiasis Free Life Expectancy (TTFLE and Trichiasis Life Expectancy (TTLE using the Sullivan method. TTLE was broken down by VA to derive TTLE with normal vision, TTLE with low vision, and TTLE with blindness. Total life expectancy at birth in 2001 was 54.2 years for males and 58.1 for females. From our Sullivan models, trichiasis life expectancy at the age of 5 years was estimated to be 7.0 (95% confidence interval [CI] = 6.2-7.8 years (12% [95% CI = 11-14] of remaining life for males and 10.9 (95% CI = 9.9-11.9 years (18% [95% CI = 16-20] of remaining life for females. Trichiasis life expectancy with low vision or blindness was 5.1 (95% CI = 3.9-6.4 years (9% [95% CI = 7-11] of remaining life and 7.6 (95% CI = 6.0-9.1 years (12% [95% CI = 10-15] of remaining life for males and females, respectively. Women were predicted to live longer and spend a greater proportion of their lives with disabling trichiasis, low vision, and blindness compared to men.The study shows the future burden associated with doing nothing to control trachoma in Southern Sudan, that is, a substantial proportion of remaining life expectancy spent with trichiasis and low vision or blindness for both men and women, with a disproportionate burden falling on women.

2006-03-01

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.

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.

Full Text Available Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05. Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

In this study, the Sudan low and the associated Red Sea trough (RST) are objectively identified using the mean sea level pressure (SLP) data from the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis dataset covering the period 1955-2015. The Sudan low was detected in approximately 60.6% of the autumn periods, and approximately 83% of the detected low-pressure systems extended into RSTs, with most generated at night and during cold months. The distribution of the RSTs demonstrated that Sudan, South Sudan and Red Sea are the primary development areas of the RSTs, generating 97% of the RSTs in the study period. In addition, the outermost areas affected by RSTs, which include the southern, central and northern Red Sea areas, received approximately 91% of the RSTs originating from the primary generation areas. The synoptic features indicated that a Sudan low developed into an RST when the Sudan low deepened in the atmosphere, while the low pressures over the southern Arabian Peninsula are shallow and the anticyclonic systems are weakened over the northern Red Sea. Moreover, stabile areas over Africa and Arabian Peninsula form a high stability gradient around the Red Sea and the upper maximum winds weaken. The results of the case studies indicate that RSTs extend northward when the upper cyclonic and anticyclonic systems form a high geopotential gradient over Arabian Peninsula. Furthermore, the RST is oriented from the west to the east when the Azores high extends eastward and the Siberian high shrinks eastward or shifts northward.

Experiences of some Canadian geologists working in Sudan are described. Glad to be back in Canada after several years of exploration work for various international exploration companies, they have fond memories of the people, who for the most part live under very primitive conditions, and constant exposure to the ravages of tribal wars. They characterize the attitude of Canadians working in Sudan towards the native population as one that puts high values on human rights, safety, work ethics, and individual responsibility. They defend Canadian presence in these far-off regions as beneficial to the native population, by bringing Canadian standards and a civilized version of industry to an area that has seen very little of that in the past. In contrast to the situation on Canadian rigs, on Chinese oil rigs favoritism and racism are the rule; the Chinese do not see that humanitarian issues are any of their concerns

The study focuses on the role of the fired clay brick making industry (BMI) on deforestation and greenhouse gas (GHG) emissions in Sudan. The BMI is based on numerous kilns that use biomass fuel, mainly wood which is largely harvested unsustainably. This results in potential deforestation and land degradation. Fuelwood consumption data was collected using interviews and questionnaires from 25 BMI enterprises in three administrative regions, namely Khartoum, Kassala and Gezira. Annual fuelwood consumption data (t dm yr -1 ) was converted into harvested biomass (m 3 ) using a wood density value of 0.65 t dm m -3 . For annual GHG estimations, the methodological approach outlined by the Intergovernmental Panel on Climate Change (IPCC) was used. According to our results, the annual deforestation associated with the BMI for the whole of Sudan is 508.4 x 10 3 m 3 of wood biomass, including 267.6 x 10 3 m 3 round wood and 240.8 x 10 3 m 3 branches and small trees. Total GHG emissions from the Sudanese BMI are estimated at 378 028 t CO 2 , 15 554 t CO, 1778 t CH 4 , 442 t NO X , 288 t NO and 12 t N 2 O per annum. The combined CO 2 -equivalent (global warming potential for 100-year time horizon) of the GHG emissions (excluding NO X and NO) is 455 666 t yr -1 . While these emissions form only a small part of Sudan's total GHG emissions, the associated deforestation and land degradation is of concern and effort should be made for greater use of sustainable forest resources and management

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

Science.gov (United States)

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.

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.

A simple spectrophotometric methods has been developed for the determination of nortriptyline hydrochloride in pure and in pharmaceuticalformulations based on the formation of ion-pair complexes with sudun II (S II ), sudan (IV) (S IV ) and sudan black B (S BB ). The selectivity of the method was improved through extraction with chloroform. The optimum conditions for complete extracted colour development were assessed. The absorbance measurements were made at 534, 596 and 649 nm for S II , S IV and S BB complexes, respectively. The calibration graph was linear in the ranges 0.5- 280. 0.5- 37.5 and 0.5 - 31.0 μg ml -1 of the drug usiny the same reagents, respectively. The precision of the procedure was checked by calculating the relative standard deviation of ten replicate determinations on 15 μg ml -1 of nortriptyline HCI and was found to be 1.7, 1.3 and 1.55% using S II , S IV , and S BB complexes, respectively. The molar absorptivity and Sandell sensitivity for each ion-pair were calculated. The proposed methods were successfully applied to the deterniination of pure nortriptyline HCI and in pharmaceutical formulations, and the results demonstrated that the method is equally accurate, precise and reproducible as the official method.

Plain radiography procedures in Sudan: examination frequency and collective dose

International Nuclear Information System (INIS)

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.

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.

Conceptualisation of Snowpack Isotope Dynamics in Spatially Distributed Tracer-Aided Runoff Models in Snow Influenced Northern Cathments

We use the Spatially distributed Tracer-Aided Rainfall-Runoff (STARR) modelling framework to explore non-stationary flow and isotope response in three northern headwater catchments. The model simulates dynamic, spatially variable tracer concentration in different water stores and fluxes within a catchment, which can constrain internal catchment mixing processes, flow paths and associated water ages. To date, a major limitation in using such models in snow-dominated catchments has been the difficulties in paramaterising the isotopic transformations in snowpack accumulation and melt. We use high quality long term datasets for hydrometrics and stable water isotopes collected in three northern study catchments for model calibration and testing. The three catchments exhibit different hydroclimatic conditions, soil and vegetation types, and topographic relief, which brings about variable degree of snow dominance across the catchments. To account for the snow influence we develop novel formulations to estimate the isotope evolution in the snowpack and melt. Algorithms for the isotopic evolution parameterize an isotopic offset between snow evaporation and melt fluxes and the remaining snow storage. The model for each catchment is calibrated to match both streamflow and tracer concentration at the stream outlet to ensure internal consistency of the system behaviour. The model is able to reproduce the streamflow along with the spatio-temporal differences in tracer concentrations across the three studies catchments reasonably well. Incorporating the spatially distributed snowmelt processes and associated isotope transformations proved essential in capturing the stream tracer reponse for strongly snow-influenced cathments. This provides a transferrable tool which can be used to understand spatio-temporal variability of mixing and water ages for different storages and flow paths in other snow influenced, environments.

2017-04-01

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.

Full Text Available Rhizobia are able to increase yield of non-leguminous species through production of phyto-stimulating substances. This study aimed to evaluate the inoculation effect of rhizobia UFRGS Lc348 and VP16 on millet and Sudan grass yield and germination, and verify the enrichment effect of culture medium with tryptophan, which leads on the rhizobium/plant interaction. Experiments in vitro and greenhouse conditions were conducted. In millet, the inoculation with VP16 grown in culture medium with or without tryptophan induces greater length of hypocotyl and epicotyl under in vitro conditions. UFRGS Lc348 treatment induces longer hypocotyls of millet under in vitro conditions. No effects were observed with the millet inoculation in greenhouse. In Sudan grass, inoculation with VP16 enriched with tryptophan increased dry matter in shoots of adult plants. In millet seedlings had achieved an increasing in elongation in vitro conditions, which could represent an adaptive advantage in the search for water and nutrients in the rhizospheric environment during the initial growth of millet. Similarly, if verified in field conditions, Sudan grass had achieved an increasing in greenhouse conditions with the inoculation of tryptophan-enriched VP16, which could be correlated with a significant gain in crop yield. Therefore, these relationships between tryptophan-enriched VP16 and Sudan grass should be verified in subsequent studies under field conditions.

Carbonization of some fast-growing species in Sudan

Energy Technology Data Exchange (ETDEWEB)

Khristova, P.; Khalifa, A.W. (Khartoum Univ. (Sudan). Forestry Dept.)

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.

Present status and future trends of industrial radioisotopes application in Sudan

International Nuclear Information System (INIS)

Salih, A.S.

2008-06-01

Radioisotopes continue to play an important role in better management of natural resources, industrial growth and environmental preservation. The success of radioisotope applications is due primarily to the ability, conferred by the unique properties of radioactive materials, to collect data, where conventional methods fail or become uneconomical. These are prompt, on-line, in-situ and do not disturb the main industrial process in any way. In Sudan, the application of these nuclear techniques has considerable economic and environmental impact. This paper casts light on the present application of radioisotopes and future trends in the country.(Author)

2016-01-01

Full Text Available Anopheles arabiensis Patton (Diptera: Culicidae is considered the most efficient malaria vector in eastern Sudan. This study aims to characterize the breeding sites of An. arabiensis throughout the year in and around Kassala town, eastern Sudan. Diverse larval habitat types were visited and characterized based on the habitat type and chemical composition. Mosquito larvae were found in many diverse habitats. During the rainy season, rain pools and water bodies created by the seasonal Gash River serve as the main breeding sites. In the dry season, irrigation canals, seepage from water pipes, neglected wells, artificial containers, and man-made ditches serve as the main breeding sites. Breeding water showed a pH of 7.9 and a low concentration of the total dissolved salts. The results of this study may be considered in planning and implementing larval control programs in the area.

Arabicization in high education: The case of medical colleges in the Sudan

Science.gov (United States)

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

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.

2011-01-01

Reproductive success is a critical component of individual fitness, and also an important determinant of growth rates of populations characterized by early maturity and high fecundity. We used radiotelemetry data collected during 2003-2008 to estimate reproductive parameters in a declining northern bobwhite (Colinus virginianus) population in South Florida, and to test hypotheses regarding factors influencing these parameters. The overall clutch size was 12.10 ?? 0.22, but females laid more eggs in their first clutch (12.43 ?? 0.24) than in subsequent clutches (10.19 ?? 0.53) within a nesting season. Daily nest survival was higher for first (0.966 ?? 0.003) than subsequent nests (0.936 ?? 0.011). Hatchability (proportion of laid eggs that hatched conditional upon nest survival to hatching) was 0.853 ?? 0.008, but was higher for nests incubated by females (0.873 ?? 0.009) than those incubated by males (0.798 ?? 0.018). The proportion of individuals attempting a second nest was 0.112 ?? 0.024 and 0.281 ?? 0.040 when the first nest was successful and failed, respectively. Hatchability was lower when the nesting habitat was burned the previous winter. We found no evidence that food strip density (a management practice to provide supplemental food) influenced any of the reproductive parameters. Mean summer temperature affected hatchability, nest survival, and proportion of nests incubated by males. Overall, the reproductive output in our study population was lower than that reported for most other bobwhite populations, indicating that low reproductive performance may have contributed to bobwhite population declines in our study site. These results suggest that current management practices, particularly those related to habitat and harvest management, need careful evaluation. ?? 2010 Springer-Verlag.

Regulatory Infrastructure for Radiation Safety and the Security of Radioactive Sources in Sudan, Present Status, Achievements and Future Challenges

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

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.

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

Directory of Open Access Journals (Sweden)

Maimuna Mohamud

2016-06-01

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

2011-01-01

This study was carried out to estimate the examination frequency and collective dose to population from CT procedures in Sudan. To calculate the annual collective dose from CT examinations a survey was done at 10 hospitals providing data of examinations frequency per day. The data of effective dose have been obtained from pervious study on effective dose per CT examination in Sudan. Then the annual examination frequency and annual collective effective dose had been calculated and discussed providing that the annual collective effective dose from CT examinations is (1482 man.Sv). The highest percentage examination frequency was for head examination (40%). The highest percentage contribution to the total collective dose from CT examinations was for abdomen examinations (32%). The calculated annual examination frequency and annual collective effective dose had been compared with the results of literature and international studies to evaluate the estimated values. The calculated annual collective dose from CT examinations is much lower comparing with the results presented in the literature. The study offers an insight on the examination frequency and the percentage of the risk from different standard radiographic examination within the country. (Author)

Influence of seasonality and gestation on habitat selection by northern Mexican gartersnakes (Thamnophis eques megalops.

Directory of Open Access Journals (Sweden)

Tiffany A Sprague

Full Text Available Species conservation requires a thorough understanding of habitat requirements. The northern Mexican gartersnake (Thamnophis eques megalops was listed as threatened under the U.S. Endangered Species Act in 2014. Natural resource managers are interested in understanding the ecology of this subspecies to guide management decisions and to determine what features are necessary for habitat creation and restoration. Our objective was to identify habitat selection of northern Mexican gartersnakes in a highly managed, constructed wetland hatchery. We deployed transmitters on 42 individual gartersnakes and documented use of habitat types and selection of specific habitat features. Habitat selection was similar between males and females and varied seasonally. During the active season (March-October, gartersnakes primarily selected wetland edge habitat with abundant cover. Gestating females selected similar locations but with less dense cover. During the inactive season (November-February, gartersnakes selected upland habitats, including rocky slopes with abundant vegetation. These results of this study can help inform management of the subspecies, particularly in human-influenced habitats. Conservation of this subspecies should incorporate a landscape-level approach that includes abundant wetland edge habitat with a mosaic of dense cover for protection and sparsely vegetated areas for basking connected to terrestrial uplands for overwintering.

To examine the influence of newspaper and Internet advertising, word-of-mouth endorsement and student experience in attracting applicants for junior medical officer positions in the Northern Territory. A retrospective study. Fifty-four applicants for junior medical officer positions. Proportion of applicants who reported newspaper advertising, Internet advertising, word of mouth or personal experience in attracting their application for an intern or resident medical officer position. Nineteen per cent of applicants saw the newspaper advertisement and 52% of the Internet advertisement. Eighty-seven per cent of applicants were influenced by word-of-mouth endorsement and 52% by student experience in the Northern Territory or Indigenous health. These results suggest that word-of-mouth endorsement has the greatest influence in attracting applicants for junior medical officer positions in Northern Territory hospitals.

Comprehensive tobacco advertising/promotion bans are effective against adolescent smoking but many developing countries have implemented only partial bans. This study examines the association between advertising/promotions exposure and adolescent cigarette smoking risk in North Africa, and possible mediation of this association by parent and peer smoking. Adolescent data (n=12 329) from the Global Youth Tobacco Survey were analyzed (Libya, 2007; Egypt, 2005; Morocco, 2006; Tunisia 2007; and Sudan, 2005). Current smoking (any cigarette use in the past 30 days) and never-smokers' initiation susceptibility (composite of openness to accepting a cigarette from a friend and intention to start smoking in the next year) outcomes were examined. Advertising/promotion exposures included media and in-person contacts. Weighted univariate, bivariate and multivariable analyses were conducted. Current smoking prevalence ranged from 5.6% (Egypt) to 15.3% (Tunisia) among boys, and 1.1% (Libya and Egypt) to 2.0% (Morocco and Sudan) among girls. Initiation susceptibility ranged from 14.1% (Sudan) to 25.0% (Tunisia) among boys, and from 13.3% (Sudan) to 15.0% (Libya) among girls. Ninety-eight percent of adolescents reported exposure to at least one type of advertising/promotion. In multivariable analyses adjusting for demographics, each type of advertising/promotion was significantly and positively associated with boys' current smoking status; most advertising/promotion exposure types were also positively associated with initiation susceptibility among boys and girls. Peer smoking only partially mediated these associations. Tobacco advertising/promotion exposure was highly prevalent and associated with adolescents' smoking risk in these countries. The comprehensiveness and enforcement of advertising/promotion bans needs to be enhanced.

The cost of antibiotic mass drug administration for trachoma control in a remote area of South Sudan.

Kolaczinski, Jan H; Robinson, Emily; Finn, Timothy P

2011-10-01

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 Objective: The objective of this study was to identify rabies virus in camels and other animals in Sudan. Materials and methods: Four camel samples were collected from Garraht Elzawia, Kab-kabia and North Darfur areas in Sudan. The samples were collected based on clinical signs. In addition, two camel samples were obtained from Khartoum and Tambool, one goat sample was collected from El-Fashir, and one cattle sample was obtained from Atbara. The samples were transported to the Veterinary Research Institute (VRI at Khartoum, Sudan for further studies. The samples were subjected for nested and hemi nested RT-PCR (hnRT-PCR along with the gold standard Fluorescent antibody test (FAT to diagnose rabies. Results: Out of eight samples, seven were found to be positive by both FAT and RT-PCR methods. The remaining one sample was positive by FAT but negative by hnRT-PCR indicating the suitablity of hnRT-PCR along with FAT for accurate diagnosis of rabies in animals. Conclusion: The study concluded that FAT and RT-PCR are useful tools for research and diagnosis of rabies. [J Adv Vet Anim Res 2016; 3(3.000: 274-277

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.

International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Sudan. February-March 1981

The IUREP Orientation Phase Mission to the Democratic Republic of the Sudan believes that the Speculative Resources of the country might fall between 20,000 and 40,000 tonnes uranium and more. This indicates that the Speculative Resources of the Sudan could be significantly higher than previously estimated (7,500 tonnes uranium) by the NEA/IAEA Steering Group on the Uranium Resources - IUREP Phase I. The Government is willing to consider valid exploration programmes presented by prospective partners as long as they serve the interests of both parties. Within the general six-year (1977/78-1982/83) plan for development of the country's mineral resources, the Ministry of Energy and Mining has set up certain priorities which it would like to see expeditiously implemented: uranium exploration and production stands high on the list of priorities. On the basis of very limited information on regional geology and on previous exploration which was available to the Mission, it is estimated that the greatest potential for the Speculative Resources of possible economic significance will prove to occur in the following geological environments of the Sudan (Red Sea Hills area is not included): precambrian basement complex, palaeozoic-mesozoic-tertiary sedimentary basins and the tertiary to recent calcretes. The IUREP Orientation Phase Mission believes that some 20 Million US$ (very rough estimate) will be needed to (1) check the validity of the basic geological concepts formulated on the uranium potential of the selected areas, (2) accumulate diagnostic geological, geophysical, geochemical data indicative of a true uranium potential there, (3) study the basement complex rocks and the sedimentary formations at least on a broad structural-stratigraphic reconnaissance basis (a tremendous amount of valuable water drilling data has accumulated over the last years for some of the selected sedimentary basins) and (4) determine the most appropriate investigation techniques to be utilized

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

Full Text Available A “turn-on” fluorescent sensor, SU-CM is synthesized for Mg2+ detection. The design of SU-CM is based on Schiff base ligand which is derived from the reaction between hydroxymethyl coumarin and aminated Sudan I dye. The low concentration of SU-CM (1 × 10−6 M exhibits a good sensitivity to Mg2+ in isopropyl alcohol solution at room temperature when excited at 372 nm. The titration of Mg2+ into SU-CM undergoes a linear enhancement with increasing concentrations of Mg2+ up to a final mole ratio of 1:1. In addition, SU-CM also shows an excellent specificity from the results that fluorescent intensity emitted at 474 nm is not influenced by adding other 12 ions. Our research suggests that SU-CM may become a favorable candidate for establishment of an efficient Mg2+ response.

Calistus Wilunda

Full Text Available South Sudan has one of the world's poorest health indicators due to a fragile health system and a combination of socio-cultural, economic and political factors. This study was conducted to identify barriers to utilisation of institutional childbirth services in Rumbek North County.Data were collected through 14 focus group discussions with 169 women and 45 men, and 18 key informant interviews with community leaders, staff working in health facilities, traditional birth attendants, and the staff of the County Health Department. Data were analysed using inductive content analysis.The barriers to institutional childbirth were categorised under four main themes: 1 Issues related to access and lack of resources: long distance to health facilities, lack of transportation means, referral problems, flooding and poor roads, and payments in health facilities; 2 Issues related to the socio-cultural context and conflict: insecurity, influence of the husband, lack of birth preparedness, domestic chores of women, influence of culture; 3 Perceptions about pregnancy and childbirth: perceived benefit of institutional childbirth, low childbirth risk perception, and medicalisation of childbirth including birth being perceived to be natural, undesirable birth practices, privacy concerns, and fear of caesarean section; and 4 Perceptions about the quality of care: inadequate health facility infrastructure and perceived neglect during admission.Multiple factors hinder institutional childbirth in Rumbek North. Some of the factors such as insecurity and poor roads are outside the scope of the health sector and will require a multi-sectoral approach if childbirth services are to be made accessible to women. Detailed recommendations to increase utilisation of childbirth services in the county have been suggested.

Full Text Available The present work aimed to observe the infection pattern of Bovine herpes virus-1 (BoHV-1 in dairy cattle with reproductive problems in Sudan. 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.

Full Text Available Background: Diarrhoeal diseases have remained a major health problem in South Sudan where they accounted 45% prevalence in under five-year olds. Between 2006 and 2007, the country reported a morbidity of 8,337 cases and 176 deaths due to diarrhoeal outbreaks. Methodology: We investigated causative agents of diarrhoeal diseases and their antibiogram in persons presenting with diarrhoea to selected health facilities in Juba. Results: Bacterial agents were prevalent in 20(6.9% of the 286 patients with 5.7%(4/70 in under five-year olds alone. S. dysenteriae 50% (10/20 accounted for the majority of the identified pathogens followed S. flexneri 25% (5/20 and S. typh 25% (5/20. Antibiotic testing showed that S. flexneri (5/5 and S. typhi (5/5 were all 100% sensitive to ceftriaxone, and gentamicin while S. dysenteriae had varying sensitivity to ciprofloxacin (70%, nalidixic acid (90%, and ceftriaxone(100%. These pathogens had 100% resistance to amoxicillin, ampicillin, tetracycline and cotrimoxazole. No difference existed in isolation rates among different age groups, educational status, gender, water drank, use of chlorine, toilet use, exposure at home to diarrhoea patient, hand washing with soap and location of residence. However, diarrhoeagenic bacteria isolation was higher for participants with no source of income (OR=6.08, p<0.05. Conclusion: With emerging menace of resistance to commonly used antibiotics in South Sudan we recommend antibiotic resistance monitoring and regulation of antibiotic use.

The micromorphological investigation on several pluristratified archaeological sites in central Sudan (Al-Khiday, left bank of the White Nile, Khartoum region, Sudan) permitted to elucidate depositional and post-depositional processes playing a role in the formation and preservation of the archaeological record. At Al-Khiday sites are located at the top of small mounds, representing the remains of Pleistocene sandy fluvial bars, and were attended since the beginning of the Holocene. The first occupation of the area corresponds to a pre-Mesolithic cemetery; than Mesolithic groups lived upon the mounds and their occupation is testified by several archaeological features: pits filled by ash and bones and living floors. Preserved Neolithic features are scarce and limited to few graves (V millennium BC). After this phase, a long gap in human attendance is registered, during which wind continued to dismantling the mounds and the sites; at ca. 2000 years BP Meroitic/Post-Meroitic groups built their tombs at the top of the archaeological sequences and altered most of the stratigraphic record. Thanks to micromorphology, it was possible to distinguish between archaeological strata still in situ and those disturbed by natural and anthropic processes; furthermore, this approach allowed to interpret the significance of several archaeological features (living floors, fireplaces, and garbage pits). In this case micromorphology of archaeological deposits was a key tool to reconstruct the depositional and post-depositional processes that contributed to the formation and preservation of the archaeological record.

2013-01-01

Full Text Available Among insect fauna reported in Sudan, Galeatus scrophicus Saunders, was detected earlier in last century, and known as a pest of sunflower. Nevertheless, very limited research works have yet been conducted on this pest. Therefore, this study was proposed to cover certain bio-ecological aspects of G. scrophicus, including host range, geographical and intra-host distributions, seasonal abundance and life cycle of pre-adult stages. Such parameters were fulfilled through surveys, field experiments and laboratory works. The results revealed seven host plants for the pest under the family Compositae, viz., Helianthus annus L., Lactuca sativa L., Lactuca taraxifolia (Willd. Schumach, Sonchus cornutus Hochst. Ex Oliv.+ Hiern, Sonchus oleraceus L., Xanthium brasilicum Vell. and Pluchea diosecoridis (L. DC., all of them, except the former species, were new records. Higher numbers of nymphs and adults were reported on the upper surfaces than on the lower sides of plant leaves. However, the pest was found in all sunflower areas in central Sudan. The seasonal counts showed that the highest population of the pest occurred in winter as compared with autumn season. On the other hand, the mean total durations of pre-imaginal stages were shorter in autumn (14.12 ± 0.15 days than in winter (25.27 ± 0.26 season. Therefore, some detrimental factors that seem to suppress the pest population buildup in autumn were suggested, and recommended for additional studies so as to design appropriate ecologically sound control measures.

Effects Of Poor Quality Desert Grass And Subsequent Refeeding On A High Plane Of Nutrition On Growth And Body Composition Of Sudan Desert Lambs

Mahgoub, O.

1994-01-01

Full Text Available Forty two, 21 males and 21 females, weaned Sudan Desert lambs were divided according to sex and live weight into three equal groups (3 x 14. Each group was randomly fed ad libitum for 11 weeks on one of three diets : humra Aristida funiculata Trin. & Rupr., humra plus limited amound of cotton seed cake, and a balanced ration. After those 11 weeks of differential feeding, each group was fed ad libitum on the balanced ration for 12 weeks. Six lambs (3 males and 3 females, 2 from each group, were randomly slaughtered at the start of the differential feeding period. Half of the remaining lambs (3 x 6 in each treatment group (3 x 12 were slaughtered at the end of the differential feeding period and the other half (3 x 6 at the end of the experiment. Live-weight growth of lambs fed humra, with or without supplemental cottonseed cake, was restricted compared to lambs fed the balanced ration. Upon refeeding, previously restricted growing lambs expressed compensatory growth. The pattern of relative increase in weight of body components was not affected by nutritional history but was influenced by body weight. Following refeeding, animals fed earlier humra with or without cottonseed cake, recovered in body conformation and composition. It was concluded that, supplementation of range lambs with a source of protein during the season of graze scarcity and afterwards feeding them on high energy yielding rations shortly before slaughter is recommended under the conditions of the Sudan.

Northern peatland carbon biogeochemistry. The influence of vascular plants and edaphic factors on carbon dioxide and methane exchange

International Nuclear Information System (INIS)

Oequist, M.

2001-01-01

The findings reported in this thesis and in the accompanying papers are based on both laboratory and field investigations of carbon transformation dynamics on the process scale and at the resolution of individual peatland plant communities. The data from one of the studies also is extrapolated in an attempt to identify environmental controls on regional scales in order to predict the response of northern peatlands to climate warming. The laboratory experiments focus on how climate variations, inducing fluctuations in groundwater level and also soil freeze-thaw cycles, influences organic matter mineralisation to carbon dioxide and methane. The field studies investigate year-to-year variations and interdecadal differences in carbon gas exchange at a subarctic peatland, and also how the physiological activities of vascular plants control methane emission rates. The main conclusions presented include: Soil freeze-thaw events may be very important for the annual carbon balance in northern peatlands, because they have the potential to increase mineralisation rates and alter biogeochemical degradation pathways. Vascular plants exert a strong influence on methane flux dynamics during the growing season, both by mediating methane transport and through substrate-based interactions with the soil microbial community. However, there are important species-related factors that govern the nature and extent of this influence. Caution has to be taken when extrapolating field data to estimate regional carbon exchange because the relevance of the specific environmental parameters that control this exchange varies depending on resolution. On broad spatial and temporal scales the best predictor of peatland methane emissions is mean soil temperature, but also microbial substrate availability (expressed as the organic acid concentration in peat water) is of importance. This temperature sensitivity represents a strong potential feedback mechanism on climate change

The effect of labor migration on relations of exchange and subordination among the Rashaayda Bedouin of Sudan.

Young, W C

This study is based on qualitative data gathered during 3 years of fieldwork among the Rashaayda, Arabic-speaking pastoralists in Sudan. Prior to 1956, every Rashiidy household was linked to other households by 3 types of social relations: 1) patrilineal descent, 2) co-residence, and 3) incorporation by purchase. After 1956, "slaves" retained membership in the tribe, but were not economically dependent on "free owners" and lived apart from "free" Rashaayda. Yet most Rashaayda sought aid from 1) patrilineal kin, 2) neighbors, and 3) former "owners" or "slaves." If the household were short of workers it could recruit extra help from neighboring households and from households that were not co-resident but were related to it agnatically. Due to rising oil prices, in 1974 opportunities for Rashiidy men in oil-exporting countries became available. The 1st Rashaayda to go to the Gulf (in 1975) were men from impoverished households who had lost most of their animals and had abandoned pastoral nomadism. There were jobs in the Gulf for expert camel racers, herders, livestock brokers, and clerks. To buy plane tickets to Mecca, the migrants sold their few remaining animals. Once these 1st migrants had found jobs, they were allowed to remain in the country as legal workers. When their terms of employment were over, most migrants returned to Sudan and transformed their wages into durable wealth. The success of this 1st group encouraged a 2nd group of less impoverished men to consider migration (1977-1980). Like the 1st group, the 2nd group had to obtain capital, contract, extra labor (at home), and investment opportunities to be able to leave. For the 2nd group, obtaining these things was more difficult: 1) they had to sell more milk and camels than they would normally, 2) they either had to travel to Saudi Arabia as pilgrims and contact employers then or purchase contracts from Rashaayda who had returned to Sudan, 3) they had to hire outsiders to work for them while they were

Population living in the Red Sea State of Sudan may need urgent intervention to correct the excess dietary iodine intake.

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

The inhabitants of western Sudan use traditional medicine for the treatment of various ailments due to lack of medical doctors and unaffordable prices of pharmaceutical products. The present study is the first documentation of the traditional plant knowledge on medicinal uses of plants by healers in Algoz (South Kordofan), Sudan. Ethnobotanical data were collected over a period from March to November 2015 using semi-structured interviews with 30 healers (24 male and 6 female) living in the investigated area. Quantitative indices such as use categories, use value (UV) and informant consensus factor (ICF) were intended to evaluate the importance of medicinal plant species. A total of 94 medicinal plants, which belong to 45 families and 81 genera, were recorded in the study area. The most represented families are Leguminosae with 20 species followed by Combretaceae (6 species), Rubiaceae (5 species) and Asteraceae (4 species). The reported species were belonging to herbs (43%), trees (28%), shrubs (22%), climbers (4%) and parasites (3%). Root and stem (21% each) were the most plant parts used. A majority of remedies are administered orally (67%) where infusion (36%) and maceration (32%) are the most used methods. The highest ICF (0.87) was reported for poisonous animal bites followed by urinary system diseases (0.89), blood system disorders (0.88) and gynaecological diseases (0.87). Anastatica hierochuntica, Ctenolepis cerasiformis, Echinops longifolius, Cleome gynandra, Maerua pseudopetalosa, Martynia annua, Oldenlandia uniflora, Opuntia ficus-indica, Solanum dubium, Sonchus cornutus, Tribulus terrestris and Drimia maritima were reported for the first time in this study. The number of medicinal plants reported in this paper reflects evidence that Algoz area had a high diversity of medicinal plants which will continue to play an important role in the healthcare system in the study area.

This study aimed to highlight nutritional status, dietary habits and sedentary patterns among university students in Khartoum state, Sudan. A cross-sectional survey was carried out among 400 university students (183 males and 217 females) from University of Khartoum, Sudan. A pre-validated self-reported questionnaire was used to collect the data. Weight and height were measured and body mass index was used to determine obesity status. Of the students, 20.5, 14.7, and 1.7 % were underweight, overweight and obese, respectively. The majority of students (85.5 %) consumed breakfast daily. About 45 and 21.8 % of students consumed vegetables and fruit, respectively, on more than 3 days a week. Fast food was consumed significantly more (p < 0.01) for more than 3 days per week by females (44.2 %) than males (27.3 %). Females (42.9 %) were more likely to watch television for 3 h and more per day than males (30.6 %) (p < 0.039). Males (33.9 %) were more prone to sleep for fewer than 7 h per day than females (23 %) (p < 0.016). The health authority in Sudan should not only focus on prevention of malnutrition among children but also should organize programs to promote healthy eating and lifestyle among children and youths to prevent and control alarming risk factors for chronic diseases.

Human influences on the health of northern peatlands

International Nuclear Information System (INIS)

Gorham, E.

1991-01-01

The present area of peat is estimated to be 342 million hectares, with an average depth of 2.3 m. Peatlands are of interest for their flora and fauna, as a habitat for wildlife, for their capacity to moderate stream flows, and for their sequestration of nitrogen and sulfur (elements important in stream and lake acidification). Of great biogeochemical significance is the role of northern peatlands in the global carbon cycle. Their total stock of carbon stored as peat is 455 Pg, or 64% of the amount present as atmospheric CO 2 , 55% of total plant biomass, and 30% of the global pool of soil carbon excluding peat. The rate of peatland sequestration of atmospheric carbon is very small compared to current emissions of 5.6 Pg from fossil fuel combustion. On the other hand, northern peatlands emit ca 0.046 gigatonnes of carbon in the form of methane, which is about 20 times as effective as a greenhouse gas than CO 2 . Human disturbances to peatlands come directly from forestry, agriculture, and fuel/horticultural peat extraction, and indirectly from destruction or utilization of surrounding upland ecosystems, deposition of pollutants, and global warming. Approaches to the study of human impacts on peatlands are outlined and suggestions are offered to guide peatland research. Peatland conservation and restoration are also briefly reviewed. 65 refs

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

Impacts of Northern Pike on stocked Rainbow Trout in Pactola Reservoir, South Dakota

Establishment of nonnative Northern Pike Esox lucius in Pactola Reservoir, South Dakota, has prompted concern among biologists about the influence of this species on the lake’s intensively managed salmonid fisheries. Ancedotal information suggests that catch rates of Rainbow Trout Oncorhynchus mykiss have declined while mean size and abundance of Northern Pike has increased, although quantitative information on diet and growth of the Northern Pike population is lacking. To address potential interactions between Northern Pike and Rainbow Trout, we assessed size-dependent predation by Northern Pike on Rainbow Trout and determined the relative energetic contribution of stocked Rainbow Trout to Northern Pike growth using bioenergetics modeling. Stable isotopes combined with traditional diet analyses revealed that smaller Northern Pike (Trout contributed less than 10% to their annual energy consumption. In contrast, larger Northern Pike (≥600 mm TL) consumed primarily Rainbow Trout, which accounted for 56% of their annual energy consumption. Combining estimates of Northern Pike predation with production costs of catchable-size Rainbow Trout revealed that annual economic losses ranged from US$15,259 to $24,801 per year. Over its lifespan, an age-10 Northern Pike was estimated to consume ~117 Rainbow Trout worth approximately $340. Thus, Northern Pike predation substantially influences salmonid management initiatives and is likely a primary factor contributing to reduced Rainbow Trout abundance and return to anglers in Pactola Reservoir. Strategies for reducing Northern Pike predation on Rainbow Trout include increasing the size of stocked fish or altering the timing and spatial distribution of stocking events.

Full Text Available Eight outbreaks of peste des petits ruminants in sheep and goats were reported in White Nile State, Sudan, between 2008 and 2009. A mortality rate of 4.2% was reported across the different outbreaks. Clinically the disease was characterised by high fever, ocular and nasal discharge, pneumonia, ulceration of the mucous membranes, diarrhoea and death. The postmortem findings included necrotic lesions in the mouth and gastrointestinal tract, and swollen, oedematous lymph nodes associated with the lungs and intestine. Of the 209 serum samples tested by competitive enzyme-linked immunosorbent assay, 113 (54% were found positive. Peste des petits ruminants virus was confirmed in tissues, nasal swabs and blood samples by immunocapture enzyme-linked immunosorbent assay, reverse-transcription polymerase chain reaction and isolation of the virus in culture of lamb testicle cells.

The within-outbreak diversity of hepatitis E virus (HEV) was studied during the outbreak of hepatitis E that occurred in Sudan in 2004. Specimens were collected from internally displaced persons living in a Sudanese refugee camp and two camps implanted in Chad. A comparison of the sequences in the ORF2 region of 23 Sudanese isolates and five HEV samples from the two Chadian camps displayed a high similarity (>99.7%) to strains belonging to Genotype 1. But four isolates collected in one of the Chadian camps were close to Genotype 2. Circulation of divergent strains argues for possible multiple sources of infection.

Directional Absorption of Parameterized Mountain Waves and Its Influence on the Wave Momentum Transport in the Northern Hemisphere

Science.gov (United States)

Xu, Xin; Tang, Ying; Wang, Yuan; Xue, Ming

2018-03-01

The directional absorption of mountain waves in the Northern Hemisphere is assessed by examination of horizontal wind rotation using the 2.5° × 2.5° European Centre for Medium-Range Weather Forecasts ERA-Interim reanalysis between 2011 and 2016. In the deep layer of troposphere and stratosphere, the horizontal wind rotates by more than 120° all over the Northern Hemisphere primary mountainous areas, with the rotation mainly occurring in the troposphere (stratosphere) of lower (middle to high) latitudes. The rotation of tropospheric wind increases markedly in summer over the Tibetan Plateau and Iranian Plateau, due to the influence of Asian summer monsoonal circulation. The influence of directional absorption of mountain waves on the mountain wave momentum transport is also studied using a new parameterization scheme of orographic gravity wave drag (OGWD) which accounts for the effect of directional wind shear. Owing to the directional absorption, the wave momentum flux is attenuated by more than 50% in the troposphere of lower latitudes, producing considerable orographic gravity wave lift which is normal to the mean wind. Compared with the OGWD produced in traditional schemes assuming a unidirectional wind profile, the OGWD in the new scheme is suppressed in the lower stratosphere but enhanced in the upper stratosphere and lower mesosphere. This is because the directional absorption of mountain waves in the troposphere reduces the wave amplitude in the stratosphere. Consequently, mountain waves are prone to break at higher altitudes, which favors the production of stronger OGWD given the decrease of air density with height.

Full Text Available This study was conducted at Um Kaddada, North Darfur State, Sudan, at two sites (closed and open for two consecutive seasons 2008 and 2009 during flowering and seed setting stages to evaluate range attributes at the locality. A split plot design was used to study vegetation attributes. Factors studied were management systems (closed and open and growth stages (flowering and seed setting. 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.

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.

Organic Matter Quality and its Influence on Carbon Turnover and Stabilization in Northern Peatlands

Turetsky, M. R.; Wieder, R. K.

2002-12-01

Peatlands cover 3-5 % of the world's ice-free land area, but store about 33 % of global terrestrial soil carbon. Peat accumulation in northern regions generally is controlled by slow decomposition, which may be limited by cold temperatures and water-logging. Poor organic matter quality also may limit decay, and microbial activity in peatlands likely is regulated by the availability of labile carbon and/or nutrients. Conversely, carbon in recalcitrant soil structures may be chemically protected from microbial decay, particularly in peatlands where carbon can be buried in anaerobic soils. Soil organic matter quality is controlled by plant litter chemical composition and the susceptibility of organic compounds to decomposition through time. There are a number of techniques available for characterizing organic quality, ranging from chemical proximate or elemental analysis to more qualitative methods such as nuclear magenetic resonance, pyrolysis/mass spectroscopy, and Fourier transform infrared spectroscopy. We generally have relied on proximate analysis for quantitative determination of several organic fractions (i.e., water-soluble carbohydrates, soluble nonpolars, water-soluble phenolics, holocellulose, and acid insoluble material). Our approaches to studying organic matter quality in relation to C turnover in peatlands include 1) 14C labelling of peatland vegetation along a latitudinal gradient in North America, allowing us to follow the fate of 14C tracer in belowground organic fractions under varying climates, 2) litter bag studies focusing on the role of individual moss species in litter quality and organic matter decomposition, and 3) laboratory incubations of peat to explore relationships between organic matter quality and decay. These studies suggest that proximate organic fractions vary in lability, but that turnover of organic matter is influenced both by plant species and climate. Across boreal peatlands, measures of soil recalcitrance such as acid

The purpose of this study was to evaluate the extent of the Hg geochemical anomaly arising in the Amiata and Tolfa complex to the coastal area of northern Latium and to examine the possible influence on this area by the Mignone River, and by the small coastal basins, which are characterized by both previous mining activities and decades of past industrial impact. The results confirm the extension of the anomaly of concentrations of Hg in the coastal area of northern Latium, with the northern sector influenced by the contributions of the Fiora and Mignone Rivers and the southern sector influenced by the contributions of minor basins. The results show high values of the Adverse Effect Index throughout the considered area and highlight the need for further investigation in order to assess the impact of human activities on the present and past values of Hg in marine sediments.

To establish the influence of acculturation strategies on quality of life, henceforth QoL. Using a cross-sectional design, two questionnaires were applied, the WHOQoL-BREF from the World Health Organization and Basabe's acculturation strategies. The questionnaires were applied to 853 Colombian and Peruvian immigrants living in Northern Chilean cities of Arica, Antofagasta and Santiago de Chile. In the psychological and social domains, as well as in the overall assessment of QoL, the most beneficial strategies are those where customs are maintained from the homeland, where "integration" then "separation" are the most beneficial. On the contrary, when the strategy for maintaining homeland customs is low, the QoL tends to be lower. The strategy of "marginalized" is associated with a lower QoL. Acculturation strategies mildly or moderately affect the psychological and social domains of quality of life as well as the overall assessment of QoL.

Full Text Available Study setting: Juba Teaching Hospital, Juba city, Republic of South Sudan, 2010. Objective: To examine, knowledge, attitude and practices of tuberculosis (TB patients enrolled on tuberculosis treatment, Juba, South Sudan. Design: Descriptive study Results: Knowledge in TB: Of the 102 patients interviewed; up to 80.4% were not knowledgeable on cause of TB, 52% did not know correct signs and symptoms of TB, 39.2% did not know overall treatment duration, 54.9% did not know the importance of strict adherence to treatment. Knowledge on correct diagnosis was 87.3% and on correct means of TB transmission was 79.4%. Practices and Attitudes: On practices; 94.1% respondents were able to perform at least one task to stop spread of disease, access to free TB test occurred in 100% of cases and for free drugs in 99% cases. Health care workers correctly suspected TB on first contact in 95.1% of cases. Patients were offered health education on drug side effects in 93.1% of cases, on HIV testing and counselling in 74.5% of cases. Disclosure of TB diagnosis by patient to family or community did not occur in 91.2% cases. Family, community and employers offered support to patients in 92.2%, 95.1% and 98% of cases respectively. Conclusion: We found key knowledge gaps among Juba TB patients enrolled on treatment. These knowledge gaps are probably responsible for the high treatment defaulter rates reported in Juba, South Sudan. Tuberculosis patients are still not interested to freely reveal disease diagnosis to members of the family and community at large.

Applying global cost-benefit analysis methods to indoor air pollution mitigation interventions in Nepal, Kenya and Sudan: Insights and challenges

International Nuclear Information System (INIS)

Malla, Min Bikram; Bruce, Nigel; Bates, Elizabeth; Rehfuess, Eva

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.

A simple, effective, and robust magnetic solid-phase extraction method was developed using magnetite/reduced graphene oxide nanoparticles as the adsorbent for the simultaneous determination of Sudan dyes (I, II, III, and IV) in foodstuffs. The magnetite/reduced graphene oxide nanoparticles were characterized by X-ray diffraction, scanning electron microscopy, and vibrating sample magnetometry. The extraction parameters including extraction time, elution solution, and elution time and volume were investigated in detail. Such magnetite/reduced graphene oxide nanoparticles based magnetic solid-phase extraction in combination with high-performance liquid chromatography and variable wavelength detection gave the detection limits of 3-6 μg/kg for Sudan I-IV in chili sauce, tomato sauce, chili powder, and chili flake samples. The recoveries were 79.6-108% at three spiked levels with the intra- and inter-day relative standard deviations of 1.2-8.6 and 4.5-9.6%, respectively. The feasibility was further performed by a comparison with commercial alumina-N. This method is suitable for the routine analysis of Sudan dyes due to its sensitivity, simplicity, and low cost. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

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.

To assess the influence of smoking and tombak (local smokeless tobacco) dipping by parents, teachers and friends on cigarette smoking and tombak dipping by school-going Sudanese adolescents. This was a school-based cross-sectional survey was conducted in 2005-2006. Logistic regression was used for the analysis. A total of 4277 Sudanese school-going adolescents (aged 11-17 years) from 23 schools who completed an anonymous self-administered questionnaire on the use of tobacco products. Main outcome measures were self-reported tobacco use during the previous month defined current tobacco use. Ever smoking, tombak dipping and other tobacco products were also considered as outcomes. After adjusting for sex, age and school grade, adolescents' smoking habits were strongly associated with the habit in their parents and friends and, more weakly, with tombak dipping by teachers. When adjusted for each other, the association with smoking in friends was unaffected and remained significant (prevalence OR (POR) of having ever smoked was 1.94, 95% CI 1.64 to 2.29; OR of being current smoker was 3.77, 95% CI 2.80 to 5.07). Tobacco smoking in friends was positively associated with adolescents ever tombak dipping (POR 1.81, 95% CI 1.41 to 2.33) and current dipping (OR 3.33, 95% CI 2.20 to 5.05). The association with parental habits was reduced but still significantly elevated. Tombak dipping by teachers was only associated with adolescents ever tobacco smoking. Tobacco use by parents, teachers and friends was associated with adolescents' tobacco habits. The influence of friends was the strongest. In developing programmes against adolescents' tobacco habits, there is need to target the influence of these 'significant others'. Sudan needs to develop and implement comprehensive anti-smoking and anti-tombak dipping legislation to reduce the growing prevalence of such habits.

Climate and anthropogenic activities such as afforestation and nitrogen deposition all impact soil pH. Understanding the spatial pattern of soil pH and the factors that influence it can provide basic information for generating appropriate strategies for soil resource management and protection, especially in light of increasing anthropogenic influences and climate change. In this study, we investigated the spatial and vertical pattern of soil pH and evaluated the influence of climate and nitrogen deposition using 1647 soil profiles 1 meter in depth from 549 plots in plantation forests of northern China. We found that soil pH decreased from the southwest to the northeast in the study region and had a similar spatial pattern before and after afforestation. Furthermore, our results show that climate and nitrogen deposition fundamentally influence the pattern of soil pH. Specifically, increasing precipitation significantly decreased soil pH (with a mean rate of 0.3 for every 100 mm rainfall, ppH (0.13 for every degree centigrade, ppH (ppH directly and indirectly through climate-plant-soil interactions. As the risks from both climate change and nitrogen deposition increase, there is an urgent need to further understanding of soil pH dynamics and to develop informed policies to protect soil resources.

Soda-anthraquinone (soda-AQ), alkaline sulphite-anthraquinone (AS-AQ) and alkaline sulphite-anthraquinone-methanol (ASAM) pulping of date palm rachis and leaves from Sudan was carried under different conditions, and pulps with variable yields and mechanical properties were obtained. The date palm rachis gave best yields and mechanical properties with the AS-AQ or the ASAM process, while the leaves were best pulped with the soda method with low yield, but very good strength properties. Blending with 10% and 30% kenaf bark pulp was beneficial, especially for the AS-AQ pulps. Totally chlorine free (TCF) bleached rachis pulps were obtained of high brightness and strength properties suitable for use in writing and printing papers.

The African Sahel region is known to be highly vulnerable to climate variability and change. We analyze rainfall in the Sahelian Sudan in terms of distribution of rain-days and amounts, and examine whether regional climate models can capture these rainfall features. Three regional models namely, Regional Model (REMO), Rossby Center Atmospheric Model (RCA) and Regional Climate Model (RegCM4), are evaluated against gridded observations (Climate Research Unit, Tropical Rainfall Measuring Mission, and ERA-interim reanalysis) and rain-gauge data from six arid and semi-arid weather stations across Sahelian Sudan over the period 1989 to 2008. Most of the observed rain-days are characterized by weak (0.1-1.0 mm/day) to moderate (> 1.0-10.0 mm/day) rainfall, with average frequencies of 18.5% and 48.0% of the total annual rain-days, respectively. Although very strong rainfall events (> 30.0 mm/day) occur rarely, they account for a large fraction of the total annual rainfall (28-42% across the stations). The performance of the models varies both spatially and temporally. RegCM4 most closely reproduces the observed annual rainfall cycle, especially for the more arid locations, but all of the three models fail to capture the strong rainfall events and hence underestimate its contribution to the total annual number of rain-days and rainfall amount. However, excessive moderate rainfall compensates this underestimation in the models in an annual average sense. The present study uncovers some of the models' limitations in skillfully reproducing the observed climate over dry regions, will aid model users in recognizing the uncertainties in the model output and will help climate and hydrological modeling communities in improving models.

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.

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

The Carboniferous Lisburne Group is a major carbonate reservoir unit in northern Alaska. The Lisburne is folded and thrust faulted where it is exposed throughout the Brooks Range, but is relatively undeformed in areas of current production in the subsurface of the North Slope. The objectives of this study were to develop a better understanding of four major aspects of the Lisburne: (1) The geometry and kinematics of folds and their truncation by thrust faults. (2) The influence of folding on fracture patterns. (3) The influence of deformation on fluid flow. (4) Lithostratigraphy and its influence on folding, faulting, fracturing, and reservoir characteristics. Symmetrical detachment folds characterize the Lisburne in the northeastern Brooks Range. In contrast, Lisburne in the main axis of the Brooks Range is deformed into imbricate thrust sheets with asymmetrical hangingwall anticlines and footwall synclines. The Continental Divide thrust front separates these different structural styles in the Lisburne and also marks the southern boundary of the northeastern Brooks Range. Field studies were conducted for this project during 1999 to 2001 in various locations in the northeastern Brooks Range and in the vicinity of Porcupine Lake, immediately south of the Continental Divide thrust front. Results are summarized below for the four main subject areas of the study.

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.

Although metallic mineral resources are most important in the economy of Mongolia, mining activities with improper management may result in the pollution of stream waters, posing a threat to aquatic ecosystems and humans. In this study, aiming to evaluate potential impacts of metallic mining activities on the quality of a transboundary river (Selenge) in central northern Mongolia, we performed hydrochemical investigations of rivers (Tuul, Khangal, Orkhon, Haraa, and Selenge). Hydrochemical analysis of river waters indicates that, while major dissolved ions originate from natural weathering (especially, dissolution of carbonate minerals) within watersheds, they are also influenced by mining activities. The water quality problem arising from very high turbidity is one of the major environmental concerns and is caused by suspended particles (mainly, sediment and soil particles) from diverse erosion processes, including erosion of river banks along the meandering river system, erosion of soils owing to overgrazing by livestock, and erosion by human activities, such as mining and agriculture. In particular, after passing through the Zaamar gold mining area, due to the disturbance of sediments and soils by placer gold mining, the Tuul River water becomes very turbid (up to 742 Nephelometric Turbidity Unit (NTU)). The Zaamar area is also the contamination source of the Tuul and Orkhon rivers by Al, Fe, and Mn, especially during the mining season. The hydrochemistry of the Khangal River is influenced by heavy metal (especially, Mn, Al, Cd, and As)-loaded mine drainage that originates from a huge tailing dam of the Erdenet porphyry Cu-Mo mine, as evidenced by δ 34 S values of dissolved sulfate (0.2 to 3.8 ‰). These two contaminated rivers (Tuul and Khangal) merge into the Orkhon River that flows to the Selenge River near the boundary between Mongolia and Russia and then eventually flows into Lake Baikal. Because water quality problems due to mining can be critical

In the agriculture-pasturage ecotone of Northern China, a typical zone with linear boundary of cropland and grassland was chosen to investigate its soil moisture regime, and the moving split-window technique was adopted to study the edge influence of soil moisture at the boundary. The results showed that the edge influence was 10 m, from 6 m within grassland and 4 m within cropland, and was categorized as the acute change type boundary. Accordingly, the farmland-grassland landscape boundary could be divided into three functional zones, i.e., grassland zone, farmland zone, and compositional ecotone zone. Soil moisture content varied abruptly in the ecotone zone, but presented linear distribution in both grassland zone and farmland zone. The average soil moisture content in grassland was about 1 g x g(-1) higher than that in farmland, which was mainly caused by the decreased capillary moisture capacity of farmland. Owing to the different vegetation cover, farmland and grassland had different transpiration and evaporation, which led to the diverse soil moisture regime, making soil water potential changed and water movement from one ecosystem to another possible.

Miombo woodlands are important in southern Africa as they occupy over 50% of the land and, their good and services support a large proportion of people in the region. Anthropogenic fires occur in miombo every year especially in the dry season (May - October). This study explores the influence of annual rainfall, elephant density, human density and corridors, and vegetation on the fire frequency. It was carried out in Niassa Reserve located in northern Mozambique, the largest and more pristine conservation area of miombo woodlands in the world. We used a time series analysis and statistical t-test of MODIS-derived Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) to explore the relationship between biomass and fire frequency. The influence of rainfall, elephants, people and vegetation on fire return was explored using a stepwise logistic regression analysis. The results of this study indicate that fire frequency is higher in places with high biomass at beginning of the dry season. In these areas fire seems to be more intense and to strongly reduce biomass in the late dry season. Land cover is the strongest predictor of fire frequency, but elephant density, annual rainfall and human corridors are also important.

Full Text Available O Sudão viveu, durante mais de duas décadas, uma guerra particularmente violenta, opondo o governo ditatorial árabe-muçulmano do Norte e os rebeldes cristãos e animistas do Sul. Por muitos considerado mais um exemplo do "choque civilizacional" previsto por Samuel Huntington (1996, o conflito sudanês esconde, no entanto, uma realidade muito mais complexa de assimetrias e desigualdades políticas e socioeconômicas profundas. Para o maior país do continente africano, as promessas de paz materializaram-se com o Acordo Geral de Paz assinado em 9 de janeiro de 2005. Momento alto de um processo tão longo e complexo como o conflito, este acordo é ambicioso, incluindo vários protocolos relativos à partilha de poder e riqueza entre as partes e prevendo, pela primeira vez, a possibilidade de secessão do Sul, mediante um referendo a se realizar ao fim de um período interino de seis anos, durante o qual vigorará um governo de unidade nacional. Mas o Sudão vive ainda uma paz incerta, dificultada não apenas pelos muitos obstáculos à implementação do acordo, mas também porque desafiada pela violência genocida no Darfur e por uma crescente instabilidade nas regiões do Leste. A partir de um olhar mais rigoroso sobre a complexidade da guerra e da paz no Sudão, procura-se avaliar os mais recentes desenvolvimentos do processo de paz e perceber que desafios se colocam agora às perspectivas de um futuro mais próspero e pacífico no país.For more than two decades, Sudan has experienced a particularly violent conflict, opposing the northern Arab Muslim dictatorial government and the southern Christian and animist rebels.

A bacterial strain (JH 70-4) exhibiting plant growth promoting characteristics (indoleacetic acid production and 1-aminocyclopropane-1-carboxylate deaminase activity), as well as heavy metal(loid) (HM) tolerance and Pb precipitation, was isolated from HM-contaminated soil at an abandoned mine site. The bacterium was identified as Pseudomonas fluorescens based on 16S rDNA sequencing. The JH 70-4 strain induced precipitation of Pb as PbS nanoparticles, confirmed by X-ray diffraction. Solution pH, incubation time, and Pb concentration influenced removal and PbS formation. Inoculating contaminated soil with JH 70-4 decreased Pb availability; exchangeable Pb decreased while organic- and sulphide-bound Pb increased. The toxicity characteristic leaching procedure showed a 65% decrease in Pb in leachate 60 d after inoculating soil with JH 70-4. Shoot and root lengths of Sudan grass grown in the inoculated soil were greater than in the uninoculated soil. Findings suggest that microbial Pb fixation is a viable strategy for remediating soil and promoting plant growth for phytostabilization of contaminated sites.
