Organ donation includes the mediums of medically and surgically transplanting the tissue or organ from one individual known as the organ donor, to be placed in the body of another individual who is referred to as the recipient. The act of transplanting may become a dire medical procedure when the organs of a recipient suffer failure, damage, injury or disease.
ABSTRACT Biogas refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Organic waste such as dead plant and animal materials, animal dung, and kitchen waste can be converted into biogas. The main objective of the study was to find out how biogas production process is well known by the local communities in Kampala, Uganda. The specific objectives were to find out the potential organic solid wastes used for biogas production, establish the benefits of u...
Abstract: Onion is an important crop both as a condiment and income generation for smallholder farmers in North western Zone of Tigray. However, Continuous use of inorganic fertilizers and inappropriate soil fertility management practices are among the major factors limiting onion productivity in the North Western Tigray. Therefore, a field experiment was undertaken in Selekleka district from October 2015 to June 2016 to assess the effects of integrated nutrient management on growth, bulb yi...
ABSTRACT Despite 19 years of its existence, organic cotton production (OCP) system has not been adopted as envisioned. This study therefore sought to identify and assess constraints to its adoption and consequent diffusion, both in temporal and spatial dimensions. A survey study was conducted using almost equal number of both organic and conventional farmers. The key methodological features involved interviewing 59 organic and 60 conventional cotton farmers using structured questionnaire. Oth...
Abstract Planting pits are rain water harvesting structures that trap water and nutrients in surface runoff and rain water falling directly into the pits. Planting pits have been promoted for improving crop yields without considering the nutrient dynamics. To contribute to this knowledge, a study was conducted to determine the soil nutrient content after four seasons of growing sorghum and pigeon pea in rotation in “Chololo” and “Five by Nine” pits. Two planting pits; “Five by Nine...
ABSTRACT The study was carried out to assess the effects of bio- slurry and farm yard manure on soil amelioration and yields of Chinese cabbage in Nyumbanitu and Itulike villages in Njombe Tanzania. Chinese cabbage is a very important crop for human nutrition as a source of vitamins, minerals and dietary fiber. However, soil acidity and nutrient deficiencies limit Chinese cabbage production in many tropical soils. The overall objective was to quantify the effects of bio- slurry and farm yard...
This study aimed to evaluate the influence of organomineral fertilizer on the growth and mineral composition of Moringa oleifera organs. The experiment included three doses of cow dung, three doses of mineral fertilizers and two doses combining mineral fertilizers and cow dung. Soil samples and samples of M. oleifera organs were analyzed. Results revealed the contribution of fertilizer to improve soil chemical properties, except pH. The best vegetative development was obtained with the d...
ABSTRACT In Nigeria, use of urine for fertigation has been limited because of its liquid form, odour and the unsanitary disposal methods. This poses great hazard to man and the environment. Converting urine into dry fertilizer product (struvite) helps extract nutrients contained in urine and also eliminates handling problems. The study was aimed at converting urine to struvite and comparing its effectiveness on plant growth with inorganic fertilizer (NPK). The study involved the extraction ...
ABSTRACT Organic-inorganic hybrid perovskite solar cells have attracted great attention in the photovoltaic research community in recent years due to its ease of processing, low cost of production, superb light-harvesting characteristics, and relatively high efficiency which make it more preferable over other existing solar cell materials. Lead-based perovskites (CH3NH3PbX3, X= Cl, I, Br) solar cells have recently attained a high efficiency of ~19.3% which far surpasses the efficiencies of m...
Abstract: Knowledge of quantity and composition of urban solid waste is required and considered as a basis for designing and operating appropriate solid waste management systems. Cognizant of this, a study was initiated to characterize the household solid waste generation rate and its physico-chemical composition based on a field survey and waste measurement in Haramaya town, Eastern Hararghe Zone, Ethiopia. For this study households were stratified into three groups based on level of their ...
Abstract Agricultural mechanization embraces the use of tools, implements, and machines for a wide range of farm operations from land preparation to planting, harvesting, omfarm processing, storage, and marketing of products while soil degradation is defined as the process which lowersthe current and/or the potential capability of soil. This study was therefore to assess the degree of mechanized agriculture and its role in soil degradation in Moiben division in Uasin Gishu district, Rift Va...
ABSTRACT Ethiopia’s agricultural sector accounts to 40 percent of national Gross Domestic Product. This shows that the sector is important in improving the livelihoods of the bulk of the population. Despite its importance, the agricultural sector in Ethiopia is characterized by low productivity. To improve this and overall economic growth, the Ethiopian government has focused on promotion of organic fertilizer use. However, adoption of organic fertilizer remains low in most parts of Ethiopi...
ABSTRACT This research was primarily designed to help improve students’ academic performance in naming organic compounds using molecular model set in Effiduase Senior High School in the Sekyere East district of the Ashanti Region. Experimental design was used for this study where the form three science classes were put into two groups. Science one students formed the control group and were taught using traditional approach while the science two students comprised the experimental group a...

ABSTRACT Taking into account the danger in the continual use of synthetic chemicals in the production of vegetables and the increase in demand for organic products, this research set out to ascertain the perception of consumers on organic products, and estimate consumer willingness to pay for organic cabbage in the Accra metropolitan area of Ghana. Furthermore, the study identifies the factors that influence the consumers‟ willingness to pay premium for organic cabbage. A face-toface ...
