Abstract: Increasing anthropogenic activities within the catchment of River Tano continues to threaten the river water quality but data is limited. Seasonal variations in some physicochemical and nutrients water quality parameters of River Tano were studied between November, 2016 and October, 2017 using electrometric and standard methods. The objective was to assess changes in physicochemical parameters and nutrient concentrations with the season and to generate useful information for water quality managers and policy makers to ameliorate the problem. The results showed significantly higher rainy season values for all the nutrients and the physicochemical parameters studied. The source of River Tano recorded pH levels lower than WHO minimum permissible level for both seasons but got corrected after 7.2 km from the source. The river was also challenged in terms of colour (61.0±4.6 NTU), total phosphorus content (0.376±0.3 mg/L), total suspended solids (69.7±24 mg/L), turbidity (96.2±21 mg/L) and electrical conductivity (252±33 µS/cm) since the levels of these parameters exceeded the permissible levels for WHO. Some physicochemical parameters and nutrients correlated strongly to indicate a possible common source to the water body. Cluster analysis extracted two clusters of the seasonal sampling sites for physicochemical parameters and three clusters for nutrients also confirming their respective possible common sources to the river. It is recommended that the buffer zone policy must be enforced to avert further deterioration of the river water quality. Industries must be compelled to treat their effluent before discharging into water bodies

Abstract: Genetic disease is caused by a gene change. Genetic disease is one of the types of diseases affecting the personal, family and social life. One of the types of genetic disease is Rabson Mendenhall Syndrome. The Rabson Mendenhall Syndrome (RMS) was first described by Rabson and Menden-hall in 1956. Rabson Mendenhall syndrome is an extremely rare genetic disorder with autosomal recessive inheritance of unknown prevalence that is estimated to affect less than 1 per million people worldwide characterized by severe insulin resistance. The present study is a case report of a patient with Rabson Mendenhall Syndrome in Iran. A 6 year old girl presented with severe hyperglycemia and loss of consciousness and acidosis. In spite of taking large doses of insulin, her sugars were uncontrolled. She had severe acanthosis nigricans. There was associated growth retardation, dental dysplasia, distent abdomen, emaciated extremities and clitoromegaly. In last admission with diabetic ketoacidosis she was treated with intravenous fluids, insulin drip, metformin and also pioglitazone, antibiotics and other supportive treatments as needed, but unfortunately after few days this treatments could not save her and patient expired. There is no complete cure for the condition and the current treatments are difficult and not very promising.

Abstract: The study dealt with the impact of human resource development on the economic development in the Sudan. It is one of the most important problems of development failure. The weakness of human capacity and the absence of the administrative system is a major obstacle to development plans. Therefore, the success of economic development depends on the human element. What are the difficulties that affect the development and performance of human resources and how to use human resources in an optimal way and to benefit from them in achieving economic development. The most important recommendations are: a. Attention should be given to increasing training opportunities, namely, human development; b. Increasing gross domestic product (GDP) of economic development, which include.

Abstract: This research deals with the reduction of colour in the pharmaceutical effluent by Treculia Africans seed coat (TA) as a coagulant using Box behnken design (BBD) from the response surface methodology (RSM). The pharmaceutical effluent was subjected to physicochemical analysis to determine the level of pollution. The coagulant was characterized by Fourier transformed infrared (FTIR) and Scanning electron micrograph (SEM). Result of the physicochemical analysis of the pharmaceutical effluent showed that the colour of the effluent is purple and its pH (8.11), Hardness (176 mg/L), phosphate 10.22 mg/L) and turbidity 560 mg/L) were found to be above WHO permissible limit of effluent disposal. BBD generated 17 experimental run in which coagulation-flocculation process was carried out. These experimental data were analyzed by analysis of variance (ANOVA) and was found to fit 2nd order polynomial model (quadratic equation). The plot of predicted versus actual data confirmed that the model describe explicitly the colour reduction efficiency. The process parameters such as coagulant dosages (100-500 mg/L), settling time (10-50 minutes) and pH (2-10) were optimized to get the best treatment condition for colour reduction efficiency. The optimum colour reduction efficiency is 64.36% at coagulant dosage of 252.32 mg/L, settling time of 25.31 minutes and pH of 2.89. The SEM image after treatment suggested that pollutant has been removed from the pharmaceutical effluent since there is change in the surface morphology of the coagulant while FTIR analysis result after treatment proposed removal and addition of bonds due to interaction between the colloid particles of the pharmaceutical effluent and the coagulant. Hence, Treculia Africans seed coat (TA) can serve as alternative coagulant for reduction of colour from Pharmaceutical effluent.
