Abstract: Transporant and conducting cadimum oxide (CdO)and maganese doped cdo (Mn:CdO) thin films were deposited using a low cost dip coating method on the glass substrate at 400◦C. For Mn doping concentration of magnanese choloride 2% (0.039582gm) was used in the spraying precursor solution. The CdO and Mn  film were investigated using uv-vis spectroscopy ,FTIR spectroscopy and thickness measurement.The optical band gap of the films decreases from 5.69 eV with increasing concentration of maganese, Optical absorption spectra of Cdo film decreases with increases doping concentration of maganese. The FTIR study reveals that the CdO and Mn the functional groups are presented. The Airwedge method of CdO and Mn: the thickness of the thin films to increases with CdO doping percentage from pure CdO 1.2504×10-3mm at 0.1% Mn 4.1344×10-3mm. It is observed that the Mn doped CdO is higher than the pure CdO.

Abstract: This study examined the challenges that women face accessing political leadership positions with particular reference to Kenyan women. The research notes that the various challenges can be linked to the social construction of gender roles in Kenya and around the world. The degree of attention given to women politicians in Kenya has considerably increased in recent years. The research however presents that women are still underrepresented in political leadership positions. It further argues that different societies are less cooperative in ensuring that women take senior leadership positions both in the public and the private sphere. The purpose of this study was to investigate the relationship between women and global politics addressing the various challenges faced by women in achieving political leadership positions in Kenya. The study also examined the performance of Kenya in gender equality highlighting the two third gender representation rule in the Kenyan parliament. The research further acknowledges that cultural practices and gender stereotyping may have influenced male perceptions on women political leadership in the past, but closely examine that good leadership is not based on gender but qualities a person possesses, regardless of their gender.

Keywords: women politicians, global politics, political leadership positions.

Abstract: Ethiopia is a country whose half of GDP lies on agricultural products. It is the birthplace of coffee Arabica. The use of pesticide is increasing worldwide, and particularly among rural populations of the developing world whose economy relies mostly in agriculture. Thus, contamination of the environment with pesticides and the pesticides entry into the food chain is unavoidable especially in developing countries. A study was conducted to investigate Organochlorinated pesticides residue levels in coffee beans commodities from Oromia region, Ethiopia. HRGC/HRMS was used for the determination of 23 organochlorine pesticides compounds in all samples. The extraction and clean up were done based on QuEChERS methods with slightly modification. ∑HCH, ΣAldrin, heptachlor, Endrin, ΣChlordane and Mirex were not detected in all of green coffee beans. Gamma-HCH, heptachlor, trans-chlordane, o,p'-DD, p,p'-DDE, o,p'-DDD, p,p'-DDD, o,p'-DDT and p,p’-DDT were detected at BQL. DDT and their metabolites were detected in most of coffee samples ranged 0.062ng/g to 51.7ng/g. Para, para’-DDT isomer was the dominant contaminant in green coffee beans. Our finding results obtained in this study provide vital information for the control and address further significance of researches on Organochlorinated pesticides in Ethiopia.

Abstract: Increasing human civilization is generating large amount of waste and sewage and at the same time demand for water is also increasing. As the available water sources are limited, recycling of sewage has become need of time. Current study involves the construction of filters using charcoal and some antimicrobial agents to filter sewage water. The filter was constructed using layers of charcoal in order of decreasing surface area of adsorption. Characterisation of the filter was done and physical parameters of sewage water before and after filtration were tested. To reduce the microbial load of the filtered water sample, addition of various antimicrobial agents into the filter was done. The antimicrobials used were silver, lemon and 10% vinegar. The microbial load of sample was determined by standard plate count technique and count was found to be TLTC (too less to count), 1.62×106 cfu/ml, TLTC (too less to count) for silver, lemon and 10% vinegar respectively. From the obtained results it can be stated that the filter is efficient in sewage water treatment. The obtained water can be recycled and used for recreational purposes like in toilets, for washing purposes, in agriculture, etc.
