Understanding policy volatility in Sudan:

"In this paper we present the findings of a qualitative investigation into some dimensions and implications of policy volatility in the realms of natural resource (NR) governance and devolution in contemporary Sudan, with particular reference to Greater Kordofan. Our goal is to map out some aspects of the interplay between volatility, disempowerment processes affecting both state agents and the rural population, and certain problems of governance that are characteristic but not unique to Sudan. In particular, we argue that volatility is a dimension of poor governance worthy of investigation in its own right, as it is a primary ingredient of what we may call a “self-disempowering state,” where adaptive learning in policy processes is impeded and successful devolution faces particularly complex obstacles. The policy domain that we consider for analysis includes laws, regulations and policies enacted under the label of “Decentralization, Land Allocation and Land Use,” as well as large development projects supporting the decentralization or devolution of NR management to local communities in the region." from Authors' AbstractPolicy Volatility, Devolution, Communities, Governance, Rural population., Decentralization, Natural resource management, Land allocation, Land use, Greater Kordofan,

Prevalence and Risk Factors of Obesity among Elderly attending Geriatric Outpatient Clinics in Mansoura City

Obesity is a major public health problem affecting all ages in both developed and developing countries. It is considered the fifth leading risk factor for deaths all over the world as about 2.8 million people die due to obesity each year directly or indirectly.  Obesity in elderly is considered one of the most serious public health challenges for all over the world. It is a complex; multifactorial disease arises from the interactions between genetic, environmental and behavioral factors together with other factors results in energy imbalance and promotes excessive fat deposition. Aim: to Determine Prevalence and Risk Factors of Obesity among Elderly attending Geriatric Outpatient Clinics in Mansoura City. Method: Descriptive, analytical, cross sectional hospital based research design was used. The study carried out on 126 elderly attending Geriatric outpatient clinics in the specialized medical hospital and general hospital in Mansoura City. Data was collected using 3 tools, socio-demographic and clinical data structured interview sheet, Health promoting Lifestyle profile II (HPLPII), Body Mass Index. Results: The results indicate that the prevalence of obesity among elderly attending Geriatric Outpatient Clinics in Mansoura City was 33.3% and there was significant relation between positive family history of obesity, unhealthy lifestyle as poor nutritional habits, and lack of physical activity, poor stress management and obesity. Conclusion: Increase awareness about obesity and healthy lifestyle is essential for elderly to prevent obesity and its complications. Keywords: Obesity, Elderly, Risk Factors, prevalence, Lifestyl

Descriptive Epidemiology of Hemophilia and Other Coagulation Disorders in Mansoura, Egypt: Retrospective Analysis.

Hemophilia represent the most severe inherited bleeding disorder (INB), it’s thought to affect inviduals from all geographical areas in equal frequency. In Egypt which has a population of approximately (80million) consanguineous marriage are frequent, therefore autosomal recessive coagulation disorders reach a higher prevalence than in many other countries

Molecular epidemiology of antibiotic-associated diarrhoea due to Clostridium difficile and clostridium perfringens in Ain Shams University Hospitals

Background: As we are living in the era of antibiotic overuse, antibiotic associated diarrhea (AAD) is considered now a distinct health problem with a need for more attention. Aim of the Study: was to perform a highly specific detection and definition of pathogenic Clostridium perfringens and Clostridium difficile related AAD in children compared to adults and geriatircs. Patients and Methods: One hundred and fifty patients diagnosed for AAD were included in this study (50 children, 50 adults and 50 geriatric patients). All of them were subjected to full medical history including complete therapeutic history of antibiotics and collection of stool sample during the attack for detection of Clostridium perfringenes enterotoxin (CPEnt) and Clostridium difficile cytotoxin by (EIA) kit. PCR detection of Clostridium perfringenes cpe gene (Coding gene for CPEnt) was performed as well. Results: Results showed that prevalence of Clostridium difficile cytotoxin was 24% while Clostridium perfringenes enterotoxin was 12% as detected by EIA in faecal specimens as a whole. Detection of cpe gene by PCR was positive in 16% of all cases. Children (OR: 4.2, 95% CI: 1.3-14.8, P_0.01) and geriatric patients (OR: 3.4, 95% CI: 1.2-13.5, P_0.02) were significantly more prone to Clostridium difficile AAD compared to adults. Also, childhood was a significant risk for Clostridium perfringens AAD (OR: 2.1, 95% CI: 0.54-7.4, P_0.04). In Conclusion: children and geriatric patients are more vulnerable to develop AAD with antibiotic abuse compared to adults.

INFLUENCE OF SPRAYING WITH GA3 AND SOME FERTILIZATION TREATMENTS ON QUALITY AND FLOWERING OF BOUGAINVILLEA GLABRA CHOISY PLANTS

A pot experiment was consummated under open field conditions at the nursery of Hort. Res. Inst., ARC., Giza, Egypt during 2015 and 2016 seasons to study the effect of spraying with gibberellic acid at 0, 500, 1000 and 1500 ppm concentrations (as a foliar spray 6 times with one month interval) and some fertilization treatments (without fertilization, NPK at 2 g/pot and phosphorein at 5 g/pot as soil drench) and their interactions on vegetative, flowering, root growth and chemical composition of 3-months-old Bougainvillea glabra plants grown in 20-cm-diameter plastic pots filled with a mixture of sand, loam and peatmoss (1:1:1, v:v). The obtained results indicated that all fertilization treatments significantly improved all vegetative, flowering and root growth traits of the plants compared to control, especially the interaction treatments between NPK at 2 g/pot and gibberellic acid at 1500 ppm in all vegetative growth characters, leaves content of chlorophylls a and b, carotenoids and total carbohydrates, N, P and K % followed by the plants treated with phosphorein at 5 g/pot as a soil drench and GA3 at 1500 ppm. Hence, in order to get the best growth and high quality plants, it is recommended to treat the plants with NPK at 2 g/pot and spraying the foliage till run-off with 1500 ppm of GA3 solution 6 times with one month interval

Role of serum allograft inflammatory factor-1 (AIF-1) in Egyptian type 2 diabetic patients

Background. Diabetes mellitus (DM) is a powerful and independent risk factor for cardiovascular disease. The atherosclerosis process in diabetes is indistinguishable from that of the nondiabetic population, but it begins earlier and is often more extensive and more severe. AIF-1 promotes chemotaxis, spreading and migration of macrophages and vascular smooth muscle cells (VSMCs) which suggest a role of AIF-1 in the atherosclerotic plaque formation. Thus, this study determines the role of AIF-1 in the Egyptian type 2 diabetic patients. Results. The level of AIF-1 was significantly higher in the type 2 diabetic group when compared to the control group (p = 0.000). In type 2 diabetic patients group, there was a significant positive correlation between CIMT and AIF-1 (r = 0.468, p = 0.000). In addition to the positive correlation between CIMT and AIF-1, CIMT in regression model analysis was significantly positive contributing to the outcome variable (AIF-1) (p < 0.05), denoting the possible role of elevated serum AIF-1 level in atherosclerotic process with further studies on larger scale needed

Effects of ammonia toxicity on growth performance, cortisol, glucose and hematological response of Nile Tilapia (Oreochromis niloticus)

Ammonia is a production limiting factor in the aquaculture media affecting fish production. A study was designed to scrutinize effects of ammonia on growth performance, survival, cortisol and hematological parameters of Tilapia fish. The study examined effects of 96 h-incubation of male and female Tilapia with 3 mg ammonium chloride per a liter of water compared to control. The study has been carried out in the physiology laboratory of the department of animal and fish production, Alexandria University. Fourteen aquaria were used (6 control and 8 ammoniated). Each aquarium contained 6 fish (half the population males and the other have females). Duration of the control reared fish was 30 days, however the duration for ammoniated group was 4 days. In all stressed fish, there found decreases in final body weight, average daily gain and specific growth rate as compared to controls. Hematological parameters revealed increases (P0.05) in total leukocyte counts in both males and females exposed to stressors. There were significant decreases (P0.05) in red blood cell, hematocrit value and hemoglobin concentration in both males and females. There were non-significant differences (P0.10) in these parameters between males and females. Exposing both male and female tilapia to ammonia, resulted in increases (P0.05) in mean corpuscular volume (MCV). Mean corpuscular hemoglobin (MCH) didn’t change in male tilapia, while females expressed increased MCH values in the ammonia condition. Mean corpuscular hemoglobin concentration (MCHC) decreased (P0.05) under ammonia with no differences between males and females. Differential leukocyte count exhibited increases (P0.05) in neutrophils in ammonia-exposed males and females and decreases (P0.05) in eosinophils and monocytes in males, but not in females. However, lymphocytes decreased (P0.05) in both females and males exposed to ammonia. Cortisol level increased (P0.05) by about 2 folds in both sexes of fish exposed to ammonia (2.95 and 2.72 vs6.40 and 6.48 ng/ml in control males and females vs ammonia-exposed males and females).Rearing tilapia fish in media containing high level (3mg/l water) of ammonium chloride not only deteriorated growth rate but it also negatively affected the health wellbeing.

Effect of FSW Parameters on The Microstructure and Mechanical Properties of T-joints between Dissimilar Al-Alloys

The main purpose of this research is to develop T-joints between the aluminum AA 2024-T4 and AA 7075-T6 using friction stir welding.  The effect of tool geometries, tool traveling speed, and rotational rate in the welded T-joints were investigated and discussed. Three different tools were used with different shoulder to pin ratios 3.28, 3.36, and 4.31. After optimization, the best tool dimension has used with the different rotational and welding speeds. Three tool traverse speeds of 50, 75, and 100 mm/min were used. Two rotation rates of 800 rpm and 1000 rpm were applied. After FSW, at a number of the above FSW parameters' combinations, macrostructure and microstructure analyses were done using optical microscopy. In order to have an insight into the mechanical properties, hardness measurements and tensile testing were carried out. Using small shoulder to pin ratio produced visually unacceptable T-joint. Opposite happened by using the tool with 4.31 of shoulder to pin ratio. Furthermore, the results showed sound T-welds with no obvious defects at high rotational rate of 1000 rpm with the two used traveling speeds. Asymmetric temperature distribution was observed between the two sides, advance side (AS) and retreating side (RS
