ABSTRACT As the prices of building materials in the country continue to increase sharply, there is growing need to source local materials as alternative for farm building constructions. This project investigates the performance of a cylindrical shell built of laterized concrete for storage of foodgrains or water. L In order to optimize the mix ratio of the constituent materials that will produce maximum strength, a mathematical model which relates the strength of laterized concrete and its ...
Abstract This research assessed the structural characteristics and quality of reinforced concrete primary materials which are cements, aggregates (fine and coarse) and reinforcing steel used in concrete works in Lagos State with a view to determining the extent to which they conform with the requirements of relevant standards. This is achieved by using relevant laboratory procedures to determine their physical, mechanical, chemical and microstructural properties and compare them with the rel...
Some industrial equipment such as electric tranformers and capacitors are located in vaults and substations on flat concrete surfaces. Due to accidents, normal routine maintenance, or replacements, this equipment may spill oil that may contain PCBs on these surfaces. These spills must be cleaned up in accordance with United States Environmental Protection Agency's (USEPA) guidelines. Current cleanup operations are abiotic in nature, encompassing both physical and chemical methods. These metho...
ABSTRACT The quality of building materials has been documented to be one of the causes of building collapse all over the world. An experimental study was conducted to determine the effect of fines (clay/silt) content in sand and water-to-cement ratio on the workability, compressive strength, tensile strength and flexural strength of concrete. A total of 270 specimens were cast and tested with varying fines content in sand of 2%, 4%, 6%, 8%, 10% and 12%; and variable water-to-cement rat...
ABSTRACT One of the ways to increase the strength properties of concrete is adding fibre material into the concrete. While to reduce a noise in construction project, a self compacting concrete was a good choice in the project. This thesis presents a study into the strength properties of self compacting beam concrete using plantain bunch fibre. Mix proportion of 1:1.82:1.27with different fractions of fibre namely: 0.00%, 0.25%, 0.50% and 0.75% by weight of cement with water cement ratio ...
Abstract The term Geopolymer was introduced to represent the mineral polymers resulting from geochemistry. The process involves a chemical reaction under highly alkaline conditions on Si-Al minerals, yielding polymeric Si-O-Al-O bonds in amorphous form. The actual compressive strength of the concrete depends on various parameters such as the ratio of the activator solution to fly ash, molarity of the alkaline solution, ratio of the activator chemicals, curing temperature etc. In recent years,...
ABSTRACT The study was conducted to evaluate practical diets for Nile tilapia Oreochromis niloticus composed of fishmeal, soybean meal, cotton seed cake meal and sunflower seed cake meal. Five isonitrogenous (30 g 100 g-1), isolipidic (10 g 100 g-1) and isoenergetic (18 kJ g-1) test diets were formulated. The control diet composed of fish meal (22%) and soybean meal (30%) as the major sources of protein. In the other test diets, fish meal was fixed at 5%, while inclusion of soybean meal, cott...
ABSTRACT The purpose of this study was to comparatively assess patients’ and nurses’ perceptions of nurse caring behaviours in Jos University Teaching hospital (JUTH) and Plateau State Specialist Hospital (PSSH) Jos. A cross-sectional descriptive survey design was employed to study 332 patients and nurses. No sampling was done as all the subjects who met the inclusion criteria were included in the study. Data were collected using a modified Caring Behavior Assessment questionnaire (CBA-...
Abstract The teaching of mathematics has been viewed classically at all onsets and specific patterns of work teaching methodologies versus the consequent content analysis have been invaluably developed at various research phases. The study looks critically at mathematics as a subject and its relative relevance within the performance environment and it entrenches the whole concept of the same to further evaluation. Study after study has at all time given us concrete evidence of the concept of ...
ABSTRACT This study analyzed state sovereignty vis-a-vis the international relationship between Uganda and Kenya towards Uganda, 1963-20 I 4, with a specific focus on commercial and economic foreign policies. It contends that until2014 Uganda remained Kenya's leading trade partner, thereby necessitating an analysis of Kenya's foreign policy tools and instruments towards Uganda. Kenya's foreign policy generally aims at protecting Kenyan territorial integrity/ security and maximizing wealth cr...
ABSTRACT This study was prompted by the recurrent Jnter-ethnic crises that have become a common feature of our national life. It was observed that the better part of the forty years of political independence in Nigeria has witnessed a disturbing trend of ethnic nationalism that has continued to threaten her corporate existence. This development, notwithstanding the interpretation that many observers may have given it, simply underscores the inability of the Nigerian political system to accom...
ABSTRACT This descriptive and quantitative study was conducted in Marmanet zone, Nyahuru district, to investigate the prevalence of and the problems which the childen suffering from behavioral disorders were facing at school. The variables measured include; the existence of such pupils in inclusive schools, the challenges which they face and the problems they cause to other pupils as well as their teachers, and how the schools have intervened for them. The study utilized a semi-structured que...
Abstract This Paper Attempts To Reflect On The Majority Of The Right To Development In Uganda As Provided In The 1995 Uganda Constitution, Against The Background Of Principles And Dimensions Of The United Nations Declaration On The Right To Development And The African Charter On Human And People's Rights (Article 22). The 1995 Constitution Recognizes The Right To Development, Stressing The Role Of People And The State In The Development In Uganda, Bringing To The Fore To The Need For Balance...
ABSTRACT The study was carried out to determine influence of drug abuse on domestic violence .ln particular, the study sought to explore the experiences of the main objectives of this study included; to establish the relationship between drug abuse and domestic violence; to identify the causes of drug abuse in Kikamula Sub County; to identify the effects of drug abuse on the community members of Kikamula Sub County; and to identify the possible measures put forward to control drug abuse in K...
ABSTRACT Many Network administrators and network analysts in organizations do not know which intrusion detection system to use. This is partly due to the fact that there is no clear comparison between the different intrusion detection systems. Therefore. organizations need concrete comparisons between different tools in order to choose which best suitc for their needs is. This research aims at comparing anomaly with signature detection methods in order to establish which is best suited to gua...
