  • Assessment of Absolute Cluster of Differentiation 4 (CD4) count in HIV patients using antiretroviral Therapy(ART) in Kosti White Nile state- Sudan

HIV infection is characterized by a gradual deterioration of immune function. CD4 cell count is used to determine how well the immune system of HIV patients because it is the first cells invaded by HIV virus. HIV patients start ART treatment if CD4 equal or less than 500 cells.    In 2014, across- sectional study conducted in ART center in Kosti , White Nile State in Sudan. The  positive HIV individuals were enrolled in this study, their ages range between 19-51 years old. The aim of this study to evaluate the immune system of HIV patient using ART. The test group was compared with control group from normal health persons, a blood samples were collected from both groups. Flow cytometer method were used to measure CD4 cells.                                                                                                                                                           

The result of this study we found a significant increasing in CD4 cell in HIV patient when starting  ART treatment ,  also it showed CD4 count increase in males more than females . Result of this study also present insignificant between result and control  result due to decrease CD4 in Sudanese. Result of the present study most age suspected to infection with HIV young persons. Also in this study found that the CD4 cells in normal health Sudanese people were  low. In Conclusion,  the present study indicated that the CD4 count can be used as  assessment method of immune system of HIV patients and to evaluate it when HIV patients start ART therapy.

  • دور المؤسسات الحكومية في حفظ وأمن الأرشيف (دراسة حالة)

للمؤسسات الحكومية دور كبير في حفظ وأمن الأرشيف وهي المراكز الرئيسية لتجميع الأرشيف القومي وقد هدفت هذه الدراسة إلي التعرف علي الطرق المتبعة في حفظ وأمن الأرشيف بالمؤسسات الحكومية  والتعرف علي مدي تطبيق المواصفات المعيارية الخاصة بحفظ الأرشيف بالمؤسسات الحكومية وقد أتبع الباحث المنهج الوصفي بدراسة حالة أرشيف الأمانة العامة لحكومة ولاية الجزيرة –السودان  والمنهج التاريخي ، وتم إجراء مقابلات شخصية مع العاملين بأرشيف الأمانة العامة للحكومة إضافة إلي الملاحظة المباشرة  ، وتوصلت الدراسة إلي عدد من النتائج من أهمها:  هنالك دور كبير يقوم به أرشيف أمانة حكومة ولاية الجزيرة في حفظ أرشيف المؤسسات الحكومية العاملة بالولاية كما أنه لا تتوافر بالمبني المعايير التي وضعت لحفظ وأمن الأرشيف وخاصة من المخاطر الطبيعية و تتبع في حفظ أرشيف أمانة الحكومة الطريقة الألفبائية العددية، ومن أهم التوصيات : أنشاء دار الوثائق الولائية استنادا علي أرشيف أمانة حكومة ولاية الجزيرة  وضرورة حوسبة أرشيف أمانة الحكومة .

  • Effects of Chlorpyrifos, Imidacloprid and neem seed powder on emergence of adults of the invasive fruit fly Bactrocera dorsalis (Diptera:Tephritidae)

Bactrocera invadens (Drew, Tsuruta and White) (Diptera:Tephritidae) is an invasive fruit fly species of Asian origin which was detected in twenty African countries. Now, the species is well established in several parts of the Sudan. The effects of Chlorpyrifos, Imidacloprid and neem seed powder on emergence of B. dorsalis adults were determined under laboratory condition. Third instars larvae were exposed to treated and untreated (control) sand.  Chlorpyrfos were tested at 2, 4,8,12,16 and 32 ppm, Imidacloprid at 2, 4, 8,16 and 32 ppm and neem seed powder at 312.5  (0.031%), 625 (0.063%),1250 (0.125%), 2500 (0.25%) and 5000 ppm (0.5%). Twenty mature third instars larvae were placed in petri dish (15 cm in diameter) to allow them to pupate in the treated and untreated sand. They were supplied with small pieces of mango fruit pulp to feed on. The experiment was replicated three times. Number of emerged adults was recorded after ten days and the mortality rate (%) was calculated. Observations on the effect of the tested chemicals on the pupae formation were taken. Data were analyzed using probit analysis. The three tested chemicals were found to be effective in inhibiting the emergence of adults but with varying degrees. The inhibition always increased with increasing the concentration of the chemicals. Chlorpyrifos was the most effective among the tested chemicals, with an LC50 of 4.13 ppm compared to Imidacloprid and neem seed powder which had an LC50 of 10.14ppm and 1299.63 ppm, respectively. Emergence of adults was completely inhibited at concentration of 32 ppm of Chlorpyrifos. Pupation was much affected by Chlorpyrifos  and Imidacloprid compared to neem seed powder.

ABSTRACT

 

     The Gezira Scheme used to be the main contributor to wheat production in Sudan, but production was sharply declined during the last few years. The main objective of this study was to appraise resource use in wheat production in the Gezira Scheme in season (2014/15).  The techniques of descriptive analysis, multiple linear regression and Cobb -Douglas production function were employed in this paper as analytical tools. Results showed that 78% of variation in wheat yield was due to variations in resource use. Elasticity of labor and capital were 0.08 and 0.14, respectively. There are technical inefficiency and technological change problems and underutilized resources. It was concluded that farmers were not optimally utilizing resources and there is an ample scope for improvements in resource utilization. The study recommended cultivation of improved varieties and application of the different agricultural operations at the optimum timing to increase productivity.

  • Effect of Powder Preparation of Clove, Ginger, Garad and Galangal on the Infestation of Sorghum Grains Caused by Khapra Beetle Larvae Trogoderma granarium

Sorghum is the most important cereal crops in the Sudan, used for both human and animal diet. Khapra beetle (Trogoderma granarium) is the major storage pest of Sorghum grains. This study was conducted to reveal the efficacy of clove, Syzygium aromaticum, ginger zingiber officinale, Garad Acacia nilotica and galangal Alppina officinarum on Khapra beetle larva. The experiment was carried out in the laboratory to rear Khapra beetle larvae on Sorghum grains treated with powder of the above botanicals crops. Ten Khapra beetle larvae were added to each treatment. Five treatments replicated five times arranged in Complete Randomized Design. The treatments were consisted of sorghum treated with powder of clove, ginger, garad and galangal, and untreated sorghum grains taken as a control. Five parameters (weight losses of sorghum grain, Khapra beetle larvae mortality, adults emerged, seed germination and seed damage) were used to show the effect of these botanical crops on Khapra beetle larvae. Khapra beetle larvae mortality and weight losses were counted every week, adults counted after their emergency (after ten weeks), seed damage and seed viability were done at the end of the experiment. The result indicated that these botanical crops significantly (p < 0.05) reduced the damage level of Khapra beetle larvae on Sorghum grains. clove powder showed the lowest weight losses, highest mortality, highest seed germination, and lowest seed damage, followed by ginger, garad, galangal and untreated Sorghum grain. From this study we can conclude that clove crop is the most important crop to control Khapra beetle larvae
