Nephrogenic metaplasia is a benign tumor characterized by urothelial tubulo - papillary structures. It is also called nephrogenic adenoma . It is a benin lesion and highly prone to recurrency. We report a case of a bladder nephrogenic metaplasia of a 65 years old patient with hematuria and POLLAKIURIA. Clinical examination was normal . Ultrasonography showed a circumferential thickening bladder , while cystoscopy showed a tumor at the dome and the right side. A transurethral resection of the bladder was performed. Histological study concluded at the existence of nephrogenic metaplasia of the bladder mucosa . The evolution was favorable and postoperative controls, including cystoscopy and intravenous urography (IVU ) at 1, 3 and 6 months were normal.

Amaranthus hybridus and Adansonia digitata leaves were analysed for their proximate and mineral elements (potassium, sodium, calcium and magnesium) using standard methods of food analysis. Ash contents of 19.72±0.5 and 10.63±0.2% for both samples revealed that they are good mineral source. 35.30±6.3 and 45.44±8.1% of carbohydrate concentrations obtained resulted in high energy values. Potassium has the highest concentration among the mineral elements analysed with 1133±4.50 and 892±3.10mg/100g, followed by calcium with 737±2.30 and 1042±6.20mg/100g for the leaves of Amaranthus hybridus and Adansonia digitata respectively. However, the ratio of sodium to potassium values obtained from the two leafy vegetables in this study indicated that they could possibly serve to reduce high blood pressure diseases in the human body. Nutrient density (ND) greater than 100% recorded for all the elements indicated that vegetables of our study can serve as source of supplement for these mineral elements.

In this paper we interest to how we can make a multiphysics model of IM, the FEM currently represents the state-of-the-art in the numerical magnetic field computation relating to electrical machines. FEM is a numerical method to solve the partial differential equations that expresses the physical quantities of interest, in this case thermal transfer and Maxwell’s equations. This approach is possible by using special simulation package frequently exploited bout in university and industry. A simple description of each one of this famous software is presented. In this moment, with the complicity of the problem, we made a decoupling between the thermal phenomena, electromagnetic and mechanics phenomena, in the first time we considers only the transient thermal and the other phenomena are in steady state, on the other hand in the second times the thermal behavior is ignored. FEM analysis is used for study state and transient mode, thermal transient, magnetic field calculation, the magnetic flux density and vector potential of machine is obtained. In this model we including, non linear material characteristics, eddy current effect, torque-speed characteristics, and magnetic analysis are investigated. Finally some simulation results of induction motor modeled by Motor-CAD and Maxwell software are given and commented.

Different management styles are in vogue in the management world and are practiced by educational managers to enhance individual and collective efficiency of employees Participative management is a practice that managers use as an attempt to satisfy employees and increase productivity. This review looks at the research on participative management and the effects on mental health of Bushehr have been a high school teacher. research methods, descriptive correlative The populations of this study consisting of all secondary school teachers in the province The school 2010-2011year and have been working as number 950 out of the total of 250 people were selected. Through participatory management information questionnaires reliability 0/85 mental health reliability 0/89 were collected. For data analysis, descriptive and inferential statistics were used The level of inferential statistics Pearson correlation coefficient and multiple regression analysis were used to analyze the data, The results showed that there is a significant positive relationship between participative management and mental health.

The study specifically described the socio-economic status of the people involved in the production, distribution and consumption of convenience foods in Lafia urban of Nasarawa state. It identified the factors that influence the entry into convenience food enterprise, factors necessitating the demand and supply of the products and examined the costs and returns of three convenience foods. The data collected were analyzed using descriptive statistics, inferential statistics (multiple regression analysis), the four points likert scale and the enterprise gross margin. The major findings indicated that female producers of convenience foods were more than male producers, the multiple regression result on the effects of socio-economic characteristics of consumers on the amount of money spent on consumer foods revealed that R2 value is 0.697. This implied that 67.7% of the total variation in output (Y) is explained by the combined influences of the independent variables in the model. The gross margin enterprise revealed that the sale of convenience foods in Lafia metropolis is profitable. The study concluded by advocating for provision of credit facilities amongst others to producers and distributors of convenience foods with limited income.

The significance of temperature and geothermal gradient in relation to hydrocarbon occurrence in the BARA Field, western Niger Delta was studied using bottom hole temperature logs. The average depth to the floor of the oil generative window (7182.3m) shows that commercial hydrocarbon accumulation still lies below the final drilled depth in the field. The average geothermal gradient of 1.74 oC /100m shows that the field is thermally mature for commercial accumulation of hydrocarbon. This is evidenced in the occurrence of hydrocarbon in the wells drilled within the field. The geothermal gradient decreases radially from the centre of the field to the edges based on the position of the five wells in the field, this is confirmed by the average thermal conductivity which tends to increase radially from the centre to the edges. Areas with high shale percentage show high geothermal gradient values while areas with high sand percentage show low geothermal gradient values. Significant hydrocarbon occurrence lies below the top of the calculated depth of oil ceiling (3508.89m) and within the oil generative window of the worldwide catagenesis range (50oC to 200oC). Rapid change in geothermal gradient occurs in intervals where there are hydrocarbon accumulation showing that, changes in geothermal gradient can be used to enhance exploration activities. The occurrence of hydrocarbon within the oil generative window in terms of temperature and depth, suggests that adjacent shales of the Agbada Formation are possible source rock.

Water is arguably one of the most priceless gift of nature that is regarded as the life line on earth, both aquatic and terrestrial organisms depends on it. The general desire to protect fresh water fisheries has led to an expansion of research into their water quality requirements, in terms of their physicochemical parameters such pH, temperature, dissolve oxygen, transparency, total alkalinity, total hardness, electrical conductivity, total dissolved matter, e.t.c. (Ibrahim et. al., 2009). The limnochemical status of River Ngadda was investigated within a twelve month period at three different sampling stations (Monday market bridge, Lagos bridge and Gwange bridge) which has varying degree of anthropogenic activities. All data gotten were compared with World Health Organization (WHO) standards. The comparison of estimated values of different parameters with W.H.O. standards indicated that the river water is polluted with reference to most parameters studied with Monday Market Bridge being most culpable, followed by Gwange and Lagos Bridges respectively, however some parameters such as temperature, pH, and TSS still within allowable permit. There is therefore an urgent need for improved water quality management within the study area with emphasis on the Monday market area more so because of the use of this water body by some inhabitants around it for household activities like cooking, washing and even drinking for both human and livestock.
