ABSTRACT The study examined the state of health and safety risk management practices in the building sector of the construction industry and has the objectives to: evaluate the construction risks inherent in the building sector of the construction industry; examine the health and safety risk management processes adopted by the construction industry in Nigeria; validate the existence of identified factor(s) militating against the implementation of health and safety practices in the constructio...
In this study, the structural investigation and design of the G+ 12 building with a flat slab as well as a regular slab were accomplished. The project was initiated by performing a literature study regarding the building design by utilising different books and articles. Them, the design attributes, equipment, and materials were chosen for the design of the proposed buildings. The building models having flat slabs and regular slabs were generated by employing the ETABS program. After that, the...
Abstract Sudanese rural tanning is an inherited craft. The methods and the indigenous materials employed by the rural tanners have remained unchanged for a long time. This is due to poverty, illiteracy, poor communications and lack of access to modern scientific technologies of leather production. As a result, the leathers produced by rural tanners are hard, crusty, liable to crack, tear. Moreover, the process period is long. The objective of the study is to investigate the possibilities of a...
ABSTRACTSolid waste (garbage) is increasingly becoming a big problem in many cities of the world andKansanga Parish in Makindye East Division- Kampala City is no exception. This report is from astudy that looks at the nature, practices, challenges, and possible solutions for garbagemanagement systems at community level in Kansanga Parish, Makindye East division. The studyplaces emphasis on domestic waste. This is because in Kansanga Parish this category generatessubstantial amounts of solid w...

The ultimate purpose of this project investigates COMPARATIVE STUDY OF THE ENGINEERING PROPERTIES OF SANDCRETE BLOCKS USING DIFFERENT BRANDS/GRADE OF CEMENT. Over 90% of physical infrastructures in Nigeria are being constructed using sandcrete blocks making it a very important material in building construction. It is widely used in Nigeria, Ghana, and other African countries as load bearing and non-load bearing walling units. For a long time in Nigeria, sandcrete blocks are manufactured in ma...
Abstract Roughly 50% of the fruit mass remains as waste after fresh consumption or processing of citrus fruits. The build-up of these wastes typically signifies an economic and environmental nuisance owing to disposal problems. However, studies have shown that biogas can be recovered as a valuable product from citrus wastes due to its high concentration in soluble sugars, making it a suitable source of cellulosic biomass. DLimonene, the major constituent of essential oil present in citrus pe...
Abstract Water is not only essential for maintaining life; it is a key component of sustainable social and economic development having links to, inter alia, health, “sense of place”, food production and industrial growth. Although progress has been made with regard to water supply, it is estimated that there are still 2.4 million people in South Africa without access to adequate water and sanitation services as defined by the United Nations (Statistics South Africa, 2008). It is possible...
ABSTRACT Engineering structures subjected to dynamic loading exhibit vibration motions. These vibrations induce accelerations on the structures and their component parts. The accelerations in turn generate inertia forces that propagate the vibrations and significantly affect the response of the structures and their components parts to external loading. This cyclic cause and effect situation result in randomly oriented and time-dependent displacements as the basic response criteria of s...
ABSTRACT The major source of water in EMENE, the study area is rain, streams and well water. Waste management has been a problem in Nigeria and so many developing nations. Most organic pollutant and pollute our underground waters. In this research, three wells were reported polluted in the compound of Adedoyin school of preliminary studies, this research was carried out to know if pollution was as a result of a dump site found inside the compound. Well B was more closer to the dump site, fol...
ABSTRACT Construction industry has complexity in it nature because it contains large number of parties such as clients, consultants and contractors. The factors that influence construction management practice differ from country to country, due to prevailing conditions. The objective of this project is to identify factors that influence construction management practice in Nigeria construction industry and elicit perceptions/ranking of the severity using relative importance index of the vario...
ABSTRACT In the recent time, the use of low cost biosorbents like bacteria, fungi, algae and some agricultural by-products have been investigated for their biosorption capacities. In this work, the biosorptions of three heavy metals (zinc, copper and manganese) from aqueous wastewater solution by five micro-organisms (Bacillus circulans, Pseudomonas aeruginosa, Staphylococcus xylosus, Streptomyces rimosus and Saccharomyces sp.(Yeast) were investigated using a combined flow and batch process...
ABSTRACT The assumed deflection shapes used in the approximate methods such asin the Rayleigh–Ritz method were normally formulated by inspection andsometimes by trial and error, until recently, when a systematic method ofconstructing such a function in the form of characteristic orthogonal polynomials(COPs) was developed in 1985. However, vibrational analyses of plates with all edges free or clamped are much more complicated. This project aims at establishing particular expressions for the...
Abstract In Nigeria, stress challenges are usually prevalent mostly in construction industry. The construction industry is a competitive and challenging industry. Therefore, most of the construction professionals suffer from stress. This study aims to explore the relationship between stressors, stress levels, performance, and coping behaviors among construction professionals. These professionals include project managers, architects, field and office engineers, designers, and other profe...
Abstract Bioremediation has been proven to be the most effective method of cleaning up oil contaminated soils through the application of nutrients and microorganism to contaminated soils. Hence, this research was aimed at investigating the effects of particle sizes on bioremediation of crude oil polluted sandy soils. Six different soil samples were sieved using the B.S sieve sizes. The sieve sizes were classified into X and Y such that X is fine to coarse sand while Y is very fine to coarse ...
