ABSTRACT This study was conducted in the context of the organic chemistry aspect of the Integrated Science course for the pre-service teachers in St. Teresa’s Colleges of Education, Hohoe in the Volta Region of Ghana. The study examined new ways of guiding students to conceptualise organic chemistry that was developed to promote in-depth understanding of aliphatic organic compounds to students. Applying a case study and action research paradigm, pre-test and post-test questions were ...
ABSTRACT The aim of this study was in two to investigate; firstly, (i) location of radiosensitive organs in the interior of four (4) paediatric anthropomorphic phantoms, and, secondly, (ii) effectiveness of single and double bismuth thyroid shields, distance between shield and phantom surface, during paediatric multi-detector computed tomography (MDCT) using fixed tube current (FTC) and automatic exposure control (AEC) on dose reduction and image quality. Four (4) paediatric anthropomorphic p...
Seeking for and provision of healthcare service has been an important phenomenon in the history of man. Thus belief: religious and cultural, play important roles in shaping the way and nature people seek for and provide medical care. Since the period of Islamic resurgence in the Kano Metropolis in the 1980s, religion has been playing pivotal role in the way and nature the price of Kano patronised medical services. Thus modern Islamic health centers were founded. These health centers provided ...
ABSTRACT A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals , plants , fungi , and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers , or exoskeletons . Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates , lipids , pr...
ABSTRACT High and sustainable kenaf production in a fragile tropical soil requires the use of soil amendments. Arbuscular Mycorrhizae (AM) are important for nutrition of plants in nutrient depleted soils of the tropics. Due to insufficient information on kenaf production using fertilizers and AM, the effects of fertilizers and AM on soil chemical properties, growth and fibre yield of kenaf were investigated. Screenhouse and field experiments were conducted at the Institute of Agricultural Res...
ABSTRACT Climate variability and change pose serious challenges to smallholder farmers and agro-pastoralists. Nonetheless, their trends and impacts on rain-fed farming system (RFFS) in semi-arid areas of Tanzania have not sufficiently been explored. This study was conducted in Iramba and Meatu districts to contribute to this knowledge gap. The study specifically (i) assessed meteorological data trends of rainfall and temperature between 1994 and 2011; (ii) determined farmers’ perception of ...
ABSTRACT This project investigated the effects of organic turmeric-supplemented-diet for rabbits on the recovery of the structural integrity of liver after exposure to ultraviolet radiation. Thirty five weaned rabbits between 8-10 weeks of age, randomly allocated to a control (A) and five (5) treatments: B, C, D, E and F were used for this experiment. Group A: fed organic feed without turmeric inclusion and not radiated, Group B: fed diet supplemented with 2% turmeric as its constituents but ...
ABSTRACT Farming has a huge potential in offering employment to the youth considering its wider labour absorptive capacity. Despite the recognition of employment creation, youth participation in working as a farmer is low due to their attitudes towards farming. The current study describes socio-economic factors that influence formation of youth attitudes in Kuresoi Sub-County, Nakuru County, Kenya. A sample of 120 youths was selected randomly from registered youth groups. Data was collected ...
This project investigated the effects of organic turmeric on the liver and oxidative stress of the brain in rabbit acutely exposed to ultraviolet radiation. Thirty five weaned rabbits between 8-10 weeks of age, randomly allocated to control (A) and five (5) treatments: B, C, D, E and F were used for this experiment. Treatment A: fed organic feed without turmeric inclusion and not radiated, Treatment B: fed diet supplemented with 2% turmeric as its constituents but not radiated, Treatm...
Abstract: Ruminants such as cattle, goats, sheep, and camels host highly diverse microbial communities in their rumens that ferment fibrous plant materials to produce energy. However, this fermentation process also generates significant amounts of volatile organic compounds and greenhouse gases, such as carbon dioxide and methane, which are released into the environment through various excretion routes. The accumulation of these gases in the atmosphere contributes to global warming and clima...
Reduced farm productivity in smallholder farms is the principal cause of food insecurity in semi- arid parts of Kenya. This is mainly attributed to soil fertility depletion, land degradation, low soil moisture and climate change. Climate change due to increased carbon dioxideemission into the atmosphere has impacted negatively on the food productivity in Africa. The objectives of this study were: 1) to determine the effect of different organic residues on soil carbon accumulation in soil. 2)...
ABSTRACT The study analyzed small-scale cassava-based farmers’ demand and utilization for microfinance banks credit in Imo State, Nigeria. The specific objectives were to: examine the socio-economic characteristics of small-scale cassava-based farmers; determine the amount of credit demanded and obtained by small-scale cassava-based farmers; estimate the factors influencing the amount of credit demanded by small-scale cassava-based farmers; estimate the determinants on the amount of credit...
A human or animal with an infection has another organism inside them which gets its sustenance (nourishment) from that person, it colonizes that person and reproduces inside them. The human with that organism (germ) inside is called the host, while the germ or pathogen is referred to as a parasitic organism. Another name for an organism that causes infection is an infectious agent. It is only an infection if the colonization harms the host i.e parasitic relationship. It feeds and multiply ...
ABSTRACT This research investigates the effects of bending on the electrical, optical, structural and mechanical properties of flexible organic photovoltaic (OPV) cells. Bulk heterojunction organic solar cells were fabricated on Polyethylene terephthalate (PET) substrates using Poly-3-hexylthiophene: [6, 6]-phenyl-C61-butyric acid methyl ester (P3HT: PCBM) as the active layer and Poly (3, 4-ethylenedioxythiophene) Polystyrenesulfonate (PEDOT: PSS) as the hole injection layer. All the organic...
ABSTRACT This study aimed at analyzing the contribution of sunflower production to the livelihood of farmers and development of small scale industries. The study collected information from 101 sample size. The methods used to collect data were Interview, Questionnaires, Participatory Observation, Focus Group Discussion and Institutional Capacity Assessment (ICA). The findings revealed that Production trend of sunflower for the past five years in 2007-20011 has a tendency of falling and rising...
