Abstract: Nanoparticles (NPs) are tiny materials having size ranges from 1 to 100 nm. They can be classified into different classes based on their properties, shapes or sizes. There are different types of NPs like men made NPs and Natural NPs but we are discussing about monometallic NPs and Bimetallic NPs. We deal with bimetallic NPs. NPs possess unique physical and chemical properties due to their high surface area and nanoscale size. Some properties like optical properties, thermal properties, magnetic properties are described here. Their reactivity, toughness and other properties are also dependent on their unique size, shape and structure. Due to these characteristics, they are suitable candidates for various commercial and domestic applications, which include catalysis, imaging, medical applications, energy-based research, and environmental applications. There are many methods for synthesis of NPs, we are using Chemical reduction by Microwave irradiation. We are synthesizing on Fe CO and Fe Mn nanoparticles. EDS technique is used for the elemental analysis or chemical characterization of a sample. Transmission electron microscopy is used to determine particle size.

Abstract: The rising energy independence and environmental concerns are key drivers in the growing popularity of electric vehicles (EVs). Because of the intermittent nature of the renewable energy sources, this may cause a high-frequency oscillation of the power system. From another aspect, all the EVs have in common the batteries, which provide the storage capability that can be effectively harnessed when the vehicles are integrated into the grid. Such a storage capability can effectively integrate wind power into the grid and all indicators signalize that the EVs are the most promising technology of the future transportation system. In this paper, different case studies are applied on one area power system to show the effect of the high wind energy penetration on the power system frequency and how the EVs can play an effective role in mitigating the power system frequency oscillation and supporting the more penetration of the wind energy into smarter electrical grids. In addition, an advanced controller has been designed to improve the frequency response and to compensate the delay of the system. The designed controller is a genetic algorithm (GA) based PID (proportional-integral-derivative) controller, it has been proposed for tuning optimized PID parameters. The results show that the controller has played an effective role in decreasing the response overshoot and settling time when used with the EVs. The used variable load, the thermal power plant parameters, and the wind turbine parameters are the same for the five case studies [1].

Abstract: This study was designed to analyze the profitability of cowpea production in Mubi South Local Government Area of Adamawa state. The primary data were collected through the use structured questionnaires. purposive and simple random sampling technique were used for the selection of study area. Descriptive statistics and inferential techniques were used as analytical tools. The result shows that most of the cowpea producer 64% were aged between 20-49 years with males dominating the business and majority of the respondents (57%) were married. Household size were relatively large, 78% had some form of formal education and a greater proportion of the respondents (86%) do not belong to any farmer’s association. Most of the respondents (61%) are full time farmer, while about 92 % of cowpea farmers had between 6 - >15 years of experience in cowpea production. Most of the farmers 78% had one form of formal education. The computed gross margin and net farm income were N289, 128.2/ha. and N286, 976.3/ha. respectively for cowpea production, which indicate that cowpea production is profitable in the area. It is recommended that, there is need for government support in terms of revitalization and priority finding extension delivery activities and agricultural development programs (ADP) in the study and area, access to subsidized farm input (such as pesticide, fertilizer and herbicide) and making credit facilities accessible and affordable to enable farmers boost their production.

Abstract: This study was to determine the prevalence of WMSDs among commercial tricycle in Borno State. Across-sectional study of the commercial tricycle riders was carried out using the standardized Nordic Questionnaire. Descriptive Statistics of mean, standard deviation, frequency and percentage were used to summarize the data, while chi-square was used to test difference in prevalence of WMSDs of selected socio-demographic and work-related characteristics of the participants at 0.05alpha level. Work related musculoskeletal disorders (WMSDs) have become a major problem in many industrialized countries and a comparable trend has also been observed in developing countries. The results showed the overall 12 months prevalence of self –reported WMSDs to be 99.7%., with the two shoulders most commonly affected with a prevalence of 89.1%. There was statistically significant difference in 12 months prevalence of WMSDs among commercial tricycle riders of different educational level (x² =11.449; P-value=0.010) with those in the age group of 18-35 years recorded the highest prevalence rate of 78.2%. There was a high 12 months prevalence of WMSDs among the commercial tricycle riders with the highest prevalence observed in the shoulder region. This study supports the need for vigilant ergonomic intervention at job sites and early ergonomic education as an integral part of apprenticeship and training of commercial tricycle riders in order to prevent the incidence and prevalence of WMSDs among this group of individuals.

Abstract: Erectile dysfunction (ED) is one of the many results of degenerative lifestyles which includes lack of exercise, poor fitness and poor nutrition, which most often results from poor circulation. Exercise, fitness and proper nutrition can improves vascular health and reverse or control the factors that contribute to erectile dysfunction. Men who are fit and exercised vigorously for 20 to 30 minutes per day are said to be less likely to have erection problems as inactive men The incidence of ED was said to be common among of men aged 18 to 59 years., and higher among men with certain medical disorders such as diabetes mellitus, heart disease, hypertension, and decreased HDL levels. Exercise has also been shown to regulates blood sugar by increasing the amount of energy utilized and helps maintain healthy weight and body composition, inaddition to increase in testosterone levels which enhances libido in male. Men who are physically inactive are more likely to develop prostate cancer, and fitness appeared to have an impact towards lowering the risk of developing prostate cancer. Maintaining a healthy weight, reducing stress and making healthy food and beverage choices, can have a positive effect on a man’s ability to achieve and maintain an erection. Excess body fat is clearly related to several health problems, including cardiovascular diseases, diabetes mellitus (type II), and certain forms of cancers, all of which are detrimental to penal erectile functioning. Men who typically consume foods that promote inflammation and contain cancer-promoting substances; that is high in fat, lots of red meat, and one that is low in fiber, fruits and vegetables, have a higher risk of developing ED than men who do not eat these foods. Eating foods that contain folic acid, vitamin C, and vitamin E support the pathways that lead to the release of nitric oxide and promotion of erectile functioning. Alcohol abuse in men for instance had been found to cause a disruption in testosterone production and shrinkage of the testes

Abstract: Stem cells are derived from embryonic and non-embryonic tissues. Most stem cell studies are for animal stem cells and plants have also stem cell. Stem cells were discovered in 1981 from early mouse embryos. Stem cells have the potential to develop into all different cell types in the living body. Stem cell is a body repair system. When a stem cell divides it can be still a stem cell or become adult cell, such as a brain cell. Stem cells are unspecialized cells and can renew themselves by cell division, and stem cells can also differentiate to adult cells with special functions. Stem cells replace the old cells and repair the damaged tissues. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. This article introduces recent research reports as references in the related studies.
