Fournier’s gangrene of the penis: A rare case report and review of the literature
Fournier's gangrene is a rare, fulminant, usually a localized disease of the external genitalia, anorectal and perineal region, with an occasional extension up to the abdominal wall. Mainly associated with men and those over the age of 50, Fournier’s gangrene has been shown to have a predilection for patients with diabetes as well as people who are long-term alcohol misusers. The usual organism is an anaerobic streptococcus synergistic with other organisms. Although considerable progress has been made in the treatment of this disease, it remains a serious and debilitating condition with a high mortality rate. Early therapy is the key, including hospitalization, debridement of the entire shaft of the penis distal to the devastated area, without excising the normal skin, parenteral broad-spectrum antibiotics, and skin grafting. We here-in present two clinical cases of Fournier’s gangrene of the external genitalia. Our case was unusual in that only the penis was involved, which is very rare.

Influence of Heat of Combustion on the Physicochemical Properties of Rice-bran Obtained from Mubi, Adamawa State, Nigeria
Rice bran, one of the most abundant and valuable byproducts produced during the rice milling process, is of steadily growing interest in recent years due to its potential health benefits. Herein, we investigate and report the physicochemical properties of rice bran obtained from Mubi, Adamawa State, Nigeria. The rice bran was initially combusted and soil samples of the baked, unbaked soil and surrounding particular area where we carried out the combustion were collected and analyzed for its physicochemical properties. The results revealed that the baked soil has a higher concentration of calcium, magnesium, potassium and sodium than the unbaked soil. Furthermore, retention of water (tension) and the ability to absorb water (infiltration) was discovered to be higher in the baked soil sample. This shows that the heat of combustion of rice bran affects the physical, chemical and mechanical properties of soil in a peculiar way.

Exercise among dialysis patients
Physical inactivity is a strong predictor of mortality in patients with end-stage renal disease and is associated with poor physical functioning. Patients with end-stage renal disease are inactive even compared to sedentary individuals without kidney disease. We sought to analyze the level of physical activity in our chronic hemodialysis patients and to identify patient barriers to physical activity. Adult patients on hemodialysis in the Department of Renal Dialysis and Renal Transplantation at the Mohammed V Military Training Hospital in Rabat were recruited and asked to complete the update Baecke physical activity questionnaire in French named AQAP (Physical Activity Self-Questionnaire) A total of 52 patients participated in the study, the mean age of the patients was 50 years ± 16.55 with extremes ranging from 24 to 76 years, sex ratio (H / F) was 1.1. The majority of participants strongly agreed that a sedentary lifestyle was a health risk and that increasing exercise was a benefit. 23% report having no physical activity. 74% of patients report difficulty in performing significant physical exertion. 17 % of patients report having a regular physical activity and sport. However, 49% of participants reported at least one barrier to physical activity. The most commonly reported barriers were fatigue on dialysis days shortness of breath and depression. Exercise provides beneficial effects in end stage renal disease, our study identified a number of barriers to physical activity that can be addressed in studies aimed at increasing levels of physical activity.

Joint Influence of Internal & External Operating Environments on Accuracy of Performance Forecasting
This article analyses the influence of the combined effect of the internal (IOE) and external (EOE) operating environments on the accuracy of performance forecasting (APF) in large manufacturing firms (LMFs) in Kenya. The objective of this study was to assess if the combined effect of the operating environments precipitated any change in any of the measures of APF. Against the backdrop of internal management conflicts of interest and exogenous events, poor forecasting in LMFs is commonplace. However, in recent times, LMFs have tended to hire skilled forecasting personnel. This study therefore, assumes that the qualified forecasting staff ensures accuracy in preparing future budgets. Both IOE and EOE are said to influence the performance of manufacturing operations. The study identified IOE and EOE influencers of firm performance and tested these against critical measures of APF. To isolate statistical significance of results, regression analysis was applied using data collected through a structured questionnaire administered among randomly selected LMFs. Results indicated that there was evidence that the combined effect of IOE and EOE had a moderating influence on APF through ROS when objective forecasting was applied, and through EV when combination forecasting was used.

Evaluation of the photocatalytic degradation of eosin red using anatase nano titanium dioxide – UV System
Synthetic dyes are essential raw materials in numerous industrial processes, which include textile, food, cosmetic, and pharmaceutical industries. However, they constitute environmental pollutants when discharged as wastewater effluents without adequate treatment. This work is focused on the treatment of a dye, Eosin Red, through the photocatalytic degradation process using anatase nano titanium dioxide. The light source for this experiment is an 8 W monochromatic UV bulb, which provides wavelength of sufficient energy to overcome the anatase titanium dioxide band energy of 3.2 eV. Dye concentration reduction was determined using a UV/Vis Spectrophotometer, with 519 nm as the wavelength of maximum absorbance of Eosin Red dye. The result obtained showed a significant degree of ER photodegration and highlighted the dependence of the photodegradation process on some influencing parameters like initial concentration of dye, catalytic loading, contact time, and pH. The kinetic study in this research indicates that the photodegradation of Eosin red dye strongly follows pseudo-first-order kinetics, as is evident in the R2 and k’ values of 0.998 and 0.0115 min-1 respectively of 10ppm Eosin red

Effective use of Abacus in the Teaching and Learning of Mathematics among class three Teachers in Public Primary Schools in Kasipul Division Rachuonyo South Sub County, Kenya
Abacus has been considered as one of the most significant tools used for teaching and learning of mathematics among primary school mathematics teachers since it helps in spurring better performance in mathematics. However, most of the teachers who use it have reported poor and perennial ineffective use of Abacus in Rachuonyo South Sub County. It is a simple mathematics tool used for calculation and easy to use when solving problems in mathematics. The study objectives were to; find out how the effective use of Abacus can be achieved; to determine age and gender differences in the effective use of Abacus, to explore the challenges faced by mathematics teachers in using Abacus and finally to establish the strategies that could ensure the effective use of Abacus in the teaching and learning of mathematics in public primary schools. Using descriptive survey design, this study was framed from Vygotsky’s constructivism theoretical perspective. This study targeted 170 public primary schools with 1,069 mathematics teachers of which568 were males and 501 were females. Purposive random sampling technique was used to select a sample size of 30% which was 51 public primary schools and 321 class three mathematics teachers. Questionnaires were used for quantitative data collection. Interviews were conducted among 51 heads of mathematics department while observation was done throughout the process. The validity of the instruments for data collection was ensured by expert judgment of the University lecturers. The reliability was determined by the Split Half method and a reliability coefficient of r=0.791was reported. Trustworthiness of the study ensured the validity and reliability of the data from the study. The quantitative data was analysed using descriptive statistics with the aid of Statistical Package for Social Sciences SPSS version 22 while qualitative data was analysed based on the construct items relating to important components on the use of Abacus. The study established that, Abacus improves performance in mathematics among pupils in primary schools in Kasipul Division. The findings of the study also revealed that, teachers had positive attitude towards Abacus. Abacus is good and effective in spurring new skills for teaching and learning of mathematics, however, most of the mathematics teachers lack the skills to use abacus effectively and need to be trained on the use of abacus. Age differences did not significantly affect the effectiveness in the use of Abacus in teaching mathematics; however, there was gender difference on the effective use of Abacus for teaching mathematics where effectiveness for male teachers was higher than that of their female counterparts. The study also established several challenges faced by mathematics teachers in the use of Abacus simply due to lack of skills. The study findings established that, mathematics teachers adopted several strategies to ensure effective use of Abacus in the teaching and learning of mathematics. The study recommended that, the Kenyan Ministry of Education should train the mathematics teachers on the effective use of abacus. Moreover, the Kenya Institute for Curriculum Development should infuse the use of Abacus into the mathematics syllabus. The significance of this study therefore is that, it is believed the findings of this study will be used by mathematics teachers to improve in teaching mathematics, provide curriculum planners with an insight to infuse effective use of abacus in mathematics curriculum development and finally it is hoped that this study will generate knew knowledge in this field of study and further research.
