Abstract The conventional method of design of reinforced concrete structures commonly used in Nigeria is the BS 8110 method. This project shO\S a comparative stud~ of BS 8110 and Eurocode 2 for the design or reinforced concrete elements of a building Vith the aim of determining "hich of the two codes provides the most economic design is carried out using manual calculations. A library complex of three storey building was selected and designed taking into account dead and live loads and assumi...
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 Fertilizer application in earthen ponds has been used as a low cost method of sustainable aquaculture production.

This study comparatively evaluates the behavior of the flexural crack and diagonal crack of ultra-high performance fiber reinforced concrete beam containing coarse aggregate (UHPFRC-CA) under applied shear load. The beams were tested under four point loading arrangement to investigate the influence that shape of steel fiber, steel fiber volume (Vf) and shear span-depth ratio (a/d) have on their crack behavior. The results obtained from the study showed that decrease in a/d significantly incr...
This research assesses the capability of existing shear capacity equations to adequately predict the shear strengths/ultimate loads of ultra-high performance fibre reinforced concrete (UHPFRC) beams in order to check their level of accuracy and to determine the equation that can be reliably used to predict/design UHPFRC beams against shear loading. Influential shear variables like shear span-depth ratio (a/d), percentage volume of steel fibre (Vf), longitudinal tensile reinforcement ratio (ρ...
Abstract Natural resource management is one of the most key focuses in today's global agenda in view of the increasing challenges of climate change and environmental degradation. Sustainable development, closely knitted with natural resource management, offers a way out to reduce climate impacts through balanced ecosystems and use of resources[1]. Various states adopt these practices in an attempt to increase their environmental resilience and economic stability. Kenya's natural resources, mi...
Some people think they can be good preachers because they know what ought to be said, but they pay no attention to how it should be said, that is, the concrete way of constructing a sermon. They complain when people do not listen to or appreciate them, but perhaps they have never taken the trouble to find the proper way of presenting their message. It should be noted that 'the obvious importance of the content of evangelization must not overshadow the importance of its ways and means.' Concer...
Abstract In the wake sustainability agendas that lead to green growth in the developing countries, the focus has been in the practice and accounting for Social, Environmental and Economic (SEE) activities by both processing and manufacturing organizations. Organizations practice social responsibilities with the view of reaping long term returns or merely complying with regulations, information which is obtained from their annual reports via various media. These reports however, in the purvie...
Abstract Crushed stone is a by-product of crushing stone which has been considered as unsalable and of no significant value. But entrepreneurs seek to use all resources and reduce waste to increase their profit margin and thus utilization of crushed stones will reduce pollution of; natural habitat, air, water and soil. Not much has been done in stone dust utilization and thus this paper examines not only the technological feasibility of using quarry dust as a concrete building material but a...
Abstract Irrigation plays a critical role in addressing food security as envisaged in Kenya’s development blueprint, the Big Four Agenda. However, the performance of any open channel irrigation system is a function of its canal conveyance efficiency, among other factors. To overcome challenges with irrigation water conveyance at the Ahero Irrigation Scheme, a Hydrologic Engineering Centre River Analysis System (HEC-RAS) model was used to simulate the flow characteristics at the tail-end se...
Abstract: Studies on the Rise of Rwanda and development are not a new concept at all. However, most of these studies do not present concrete criteria for determining how the country has marketed herself as a regional hub for international conferences. This study attempts to fill the academic gap by examining other international conference cities and identifying the similarities or/ and differences they have with Kigali City. To achieve these objectives, this thesis employed a qualitative res...
Abstract: The world is continually hearing about the unrelenting expansion of the use of digital technologies like social media around the globe. The relevance of social media channels to diplomacy goes far beyond usage numbers. The universal use of social media has important strategic implications for the diplomatic community because it has fundamentally changed the ways that governments engage with their citizens and position themselves on the global stage. Social media has fundamentally i...
