Abubakar Tafawa Balewa University

Bauchi, Nigeria

Abubakar Tafawa Balewa University , is a federal university of technology located in Bauchi, northern Nigeria. The university is named after the first Prime Minister of the Federal Republic of Nigeria, Sir Abubakar Tafawa Balewa. The motto of the university is DOCTRINA MATER ARTIUM, which literally means "Education is the mother of the practical arts". The university is known for having one of the best Engineering programme in Nigeria.The Abubakar Tafawa Balewa University was established in 1980 as Federal University of Technology, Bauchi, Nigeria. The institution's first set of students were admitted in October 1981 for pre-degree and remedial programmes while the degree courses of the School of Science and Science Education began in October 1982. On 1 October 1984, the University was merged with Ahmadu Bello University Zaria, Nigeria with a subsequent change of its name to Abubakar Tafawa Balewa College, Ahmadu Bello University, Bauchi Campus. The University regained its autonomous status in 1988 following a general demerger of such institutions. This was followed by a subsequent change of its name to Abubakar Tafawa Balewa University, Bauchi.The Academic pattern of the University was formulated in 1980 after consultation with invited subject experts from Nigeria, United Kingdom and the United States of America. The solid foundation upon which the curriculum of the former Federal University of Technology was built was responsible for its sustenance all through the years of its existence and in particular after the merger. The curriculum adopted was purely applied in nature, for a technologically based institution and it is this theme that is being maintained in all the units of the University.Over two decades in existence, the University has come a long way in addressing some of the engineering, agricultural, scientific, environmental and technological challenges common to third world nations like Nigeria having been adjudged the fifth best University with one of the best engineering programmes in Nigeria.The University offers degrees through six schools: the School of Engineering, Science, Environmental Technology, Agriculture, Management Technology and the School of Technology Education. The University offers entry level bachelors degrees as well as both Masters and Doctorate degrees. Each school is headed by a Dean who reports directly to the Vice Chancellor. The Vice Chancellor is the executive head of the University. The Vice Chancellor is appointed by the Federal Government of Nigeria on recommendation by the Governing Council of the University. The current Vice Chancellor is Professor M. H. Muhammad. Wikipedia.

Abdominal pregnancy has remained a big challenge worldwide especially in developing countries where there are limitations in diagnostic resources. The most important approach is to be vigilant for the unexpected as most patients present with no specific symptoms or clinical signs. It also poses great challenges in diagnosis and management, and is associated with a lot of morbidity and mortality. This series of six cases, each presenting in a peculiar way, typically illustrates these issues. The cases were managed in three different hospitals in the last 15 years. These series is aimed at highlighting the atypical presenting features of advanced abdominal pregnancy and the need for vigilance when there is suspicion of a case. It is also aimed at showing the difficulty of diagnosis and management of advanced abdominal pregnancy in low resource environment. © 2013 Elsevier Ireland Ltd. All rights reserved.

The aim of this paper is to systematically determine the effect of scale on masonry structural behaviour under various loading conditions. Small scale models have been employed to understand masonry structural behaviour over the years, because testing prototype masonry structures is both costly and challenging to undertake in a controlled laboratory environment. A programme of tests have been carried out at four scales namely prototype, half, fourth and sixth scale under five different loading conditions; compression, shear, diagonal tension, flexure and bond tension, with a view to understanding how each of these conditions affects masonry structural behaviour over the range of scales enumerated. The results show that scale or size effect is mostly pronounced in the masonry compressive strength. © 2010 RILEM.

An adsorption study was carried out with powdered activated carbon (PAC) prepared from leather buffing waste by steam activation after carbonization at temperatures between 500-800°C. Adsorption performance of each activated carbon test was carried out using methylene blue, a medium sized dye molecule commonly used to determine adsorption efficiency of adsorbents. The results obtained reveal an increase in adsorption of methylene blue with decrease in temperature of carbonization indicating that lower temperature of carbonization yields carbon with greater adsorption capacity. Also, this suggests that carbonization at temperatures below 500°C may be preferred. The carbon had adsorption capacity of 90.4mg/L of a solution containing 100mg/l of the dye. The effect of time and carbon dosage on adsorption indicates that activated carbon from leather buffing waste is competitive with the reference carbon indicating it can be used to adsorb dyes, decolorize organic compounds and treat waste water. Data corresponding to the adsorption of methylene blue onto the best activated carbon produced (BD5) using the Freundlich and Langmuir adsorption isotherm model established a fit with an R2value of 0.915 and 0.989 respectively.

The use of the internet in the 21st century is indisputable to the people worldwide. People have become dependent on the internet's connectivity to conduct business, share information, and collaborate. Yet, some people use the internet as an avenue for illegal activities such as breaking into other people computers or networks, damaging and stealing information, and blocking or denying legitimate users from services they subscribed. Actually, these illegal activities are made possible because the internet is based on all end users being trusted to act appropriately [20]. Nevertheless, security experts have suggested in some researches that Internet Service Providers (ISPs) should be called to the chain of security responsibilities because they believe that ISPs are in suitable position to protect (police) the internet. They argue that ISPs control the gateway through which internet security breaches pass to their customers. Moreover, they consider that ISPs can use advanced technologies to detect illegal activities. In addition, ISPs have broader knowledge of cyber threats that affect internet users and businesses. The purpose of this paper is to review literatures on the responsibilities of ISPs in securing their customers' network, and find out whether there are legal provisions, or liabilities that are bindings on the ISPs to provide security for their customers. The questions here, are ISPs responsible for end users' network security? Are there legal provisions binding ISPs to provide the network security to their subscribers? In addition, what are the recommended security considerations they should be responsible to provide?. © 2005 - 2013 JATIT & LLS. All rights reserved.

Today, there is a tendency to forget that there are still many locations in the world which do not have an electrical connection to a central utility network. Furthermore, in many places due to remoteness and cost, it is unlikely that a main grid connection will ever be established. However the need for power still exists. Nigeria is abundantly blessed with all major sources of energy; solar power, wind, geothermal and bio-energy. But my country lacks the expertise to control and utilize these sources of power. Many remote areas of developing countries like Nigeria lacked supply of conventional energy sources (oil, grid extension) due to cost and poor infrastructure. However, many of them are also fortunate enough to live in the proximity to potential indigenous renewable energy sources such as hydro, solar, and wind. This paper presents the concept of using more than one renewable energy sources/technologies in solving the energy problem of rural or remote centers, especially in a region with renewable energy potential. © 2015 IEEE.

Nowadays information technology (IT) adoption is considered to be the main driver of improved performance in all types of knowledge-based organizations. This article is an attempt to provide insight into whether IT adoption (ITA) increases innovation tendency by universities and what kind of influence the level of staff capabilities exerts in this relationship. By using data from a survey of 228 individuals drawn from universities in Northern Nigeria, three models were developed and tested by means of parametric analyses of multiple correlation and regression to explain the relationships between ITA, staff knowledge capabilities (SKC) and universities’ innovative behaviour (UIB). Results of the analysis show a positive link between the variables, signifying that universities exhibiting high level of innovative output are those that have intensely adopted IT and employ and train staff to increase their knowledge capabilities. © 2015 Intellect Ltd Article.

Removal of undesirable components is essential to improve the nutritional quality of legumes and effectively utilize their full potential as poultry feed ingredient. It is widely accepted that simple and inexpensive processing techniques are effective methods of achieving desirable changes in the composition of seeds. Different authors have reported that soaking, cooking, toasting, autoclaving, microwave cooking, pressure cooking, extrusion cooking, germination and chemical treatment improve the quality of legumes because of the removal or inactivation of some anti-nutritional factors. In many instances, usage of only one method may not effect the desired removal of anti-nutritional substances and a combination of two or more methods may be required. © Asian Network for Scientific Information, 2010.

Cement production process has been highly energy and cost intensive. The cement plant requires 8784 h per year of the total operating hours to produce 640,809 tonnes of clinker. To achieve effective and efficient energy management scheme, thermal energy audit analysis was employed on the pyroprocessing unit of the cement plant. Fuel combustion generates the bulk of the thermal energy for the process, amounting to 95.48% (4164.02 kJ/kgcl) of the total thermal energy input. Thermal efficiency of the unit stands at 41%, below 50-54% achieved in modern plants. The exhaust gases and kiln shell heat energy losses are in significant quantity, amounting to 27.9% and 11.97% of the total heat input respectively. To enhance the energy performance of the unit, heat losses conservation systems are considered. Waste heat recovery steam generator (WHRSG) and Secondary kiln shell were studied. Power and thermal energy savings of 42.88 MWh/year and 5.30 MW can be achieved respectively. Financial benefits for use of the conservation methods are substantial. Environmental benefit of 14.10% reduction in Greenhouse gases (GHG) emissions could be achieved. © 2009 Elsevier Ltd. All rights reserved.

This paper employs a MATLAB based system identification toolbox (SID) to obtain a mathematical model of a loss-in-weight (LIW) feeder. In this study a pseudorandom binary sequence (PRBS) was used to excite a loss-inweight feeder used in a cement manufacturing process. The input and output data were then processed using a MATLAB system identification toolbox that yielded an ARMAX model of the process. The identified model was sufficiently validated in the MATLAB control toolbox. Details of data capture, system identification, open-loop simulation, and validation tests were presented in this paper. The results are well assuring to control practitioners and students that MATLAB SID toolbox is a perfect candidate for offline process identification. © Springer-Verlag Berlin Heidelberg 2015.

The effectiveness of different strains of Metarhizium anisoplae Metchn (V275, V245 & Ma23), Verticillium lecanii Zimm (KV71, KV181 and KV183) and Paecilomyces lilacinus Thom (P251) as biological control agents were evaluated against Maize Weevil (Sitophilus zeamais Motsch). The experiments were laid down in completely randomised design with eight treatments. Each treatment was replicated three times. Overall assessment of the bioassay experiments showed that all the fungal isolates tested were significantly (P < 0.05%) better than the control treatment. However, the percentage cumulative mortality of S. zeamais was observed to be higher in treatments where insects were treated with higher concentrations of conidia. Among all the strains evaluated V275, V245 and KV 183 proved to be more effective than the rest of the isolates. In other words, the mortality of S. zeamais was found to be highly dependent on conidia concentration and isolates V275, V245 and KVL183 provided a higher protection of maize grain against S. zeamais at all the levels of conidial concentrations tested. In conclusion, all the tested isolates especially V275, V245 and KV183 have potential value to provide protection to maize grain against S. zeamais. The result also highlights the need for screening of more virulent isolates against S. zeamais in the management of the insect. © 2010 Taylor & Francis.
