Item A Comparative Analysis of Grillage method and Beam line analysis of a reinforced concrete waffle bridge deck(Nigeria Journal of Engineering and Applied Sciences (NJEAS), 2022-01-12) 8. Adamu, H. N.; Abbass, B. A.; Abubakar, M.; Yusuf, A.; Kolo, D. N.; Shehu, M.The analysis of reinforced concrete waffle bridge deck using chanchaga bridge as a case study was carried out with the aid of computer program written in MATLAB. The bridge deck which is a beam bridge was idealized to be a waffle slab. A mathematical model of the bridge was developed using the method of grillages because very complex shapes of problem domain with prescribed conditions can be handled easily using the method. The bridge deck was modelled as interconnection of grid elements. The analysis was carried out using direct stiffness matrix method. The nodal displacements and the resulting static internal forces; shear forces, bending moments and twisting moments of each grid element were determined using the matrix. The results obtained using the method of grillages were then compared with beam line analysis and the former method gave a 10% decrease in forces which will result in the reduction of overall design and materials by 10%.Item A Comparative Study of Library and Information Science (LIS) Education A Case of Kenya and India(The Global Education Network in Collaboration with The University of Lome, Togo, 2020) Goshie, Rhoda WusaItem A Comparative Study of Library and Information Science (LIS) Education: A case of Kenya and India(The Global Education Network in Collaboration with the University of Lome, Togo, 2020) Goshie, RhodaLibrary and Information (LIS) as the name implies is a combination of two fields namely library and information science. The joint term is associated with schools of library and information science (SLIS). Most of the education transformation efforts worldwide are focused on how education, which is very laudable, but very little, is being done about the what. in this era of knowledge economy and information society, information is the driving force of any kind of societal development in all sectors of economy, intellectual and culture. The key is the delivery of information to the society. LIS is the academic and professional study of how information and information carriers are produced, disseminated, discovered, evaluated, selected, acquired, used, organized, maintained and managed. The origin growth and development of library programs varies from one country to another. The emergence of information and communication technologies (ICTs) particularly, the internet and other related technologies have brought about a fundamental and dramatic shift in global educational system which is changing by day. The purpose of this paper is to compare the library and information science (LIS) education in Kenya and India for the progress of the programs in other parts of the country. The paper listed the challenges that could likely stand as a stumbling block to LIS education. Recommendations were provided at the end of the paperItem A STUDY OF THE EFFECT OF DEGRADATION ON INDUSTRIAL GAS TURBINE PERFORMANCE(Journal of Science, Technology, Mathematics and Education (JOSTMED), FUT Minna, 2016-03-15) Nasir, .A.; Usman, .S. A.; Mohammed, .A.; Muhammed, .S. N.; Bori IgeComponent degradation is a very common problem associated with operating industrial gas turbines. The major components so affected by this phenomenon are compressor, combustor and turbine blades. This paper studied the effect of degradation on gas turbine performance. The study involved the analyses of operating parameters effects for Siemens gas turbine engines model SGT5 – 2000E coded GT11 and GT21 in the power stations at Geregu power stations. The parameters considered were ambient temperature, exhaust temperature, combustion chamber pressure and turbine entry temperature, GT11 is degraded while GT21 is newly installed engine both in the same location at Geregu I and II power stations in Ajaokuta, Kogi State in the North central part of Nigeria.Simulations were carried out using Gas turb 11 simulation software, results of engine performance parameters were compared and it was revealed that due to component degradation, the turbine entry temperature (TET) increased to 1049.67oC, the fuel flow increased by 8.49% and power fell by 7.14%. Consequently, the cost of power loss is one hundred and eighty-seven million, one hundred and eleven thousand, seven hundred and fifty-three naira ninety-two kobo (₦187,111,753.92k) over a period of one year for the degraded gas turbine.Item An evaluation of mechanical properties and estimation of environmental reduction factors in welded API X70 steel pipeline in natural seawater(Taylor & Francis Ltd, 2023-06-20) Oyewole, Adedipe; Adulrahman, Bala Gambo; Joseph, Babalola Agboola; Kafayat Toyin, Obanimomo; Asipita, Salawu AbdulrahmanDue to the detrimental effect of damage induced by seawater in pipeline structures, there is a need to investigate the effects of natural seawater and air environments on mechanical properties of representative pipeline materials, to obtain useful data for estimation of their service lives. Hence, in this work, a X70 steel pipeline plate was welded using submerged arc welding technique; and subjected to air and natural seawater environments. Test specimens were soaked in seawater for twelve months at 28 °C. The parent plates, weld regions and the heat affected zones were investigated by evaluating their mechanical properties and fracture surfaces. The experimental findings revealed that the tensile strengths of parent and weld were 634.00 MPa and 674.00 MPa respectively, while the compressive stresses were 750.10 MPa and 750.40 MPa respectively with highest hardness value of 239HV. The findings also revealed that weld area and heat affected zone depend on material thickness, heat input and possible effect of residual stresses in the weldment. The fracture surfaces of test specimens showed combination of brittle and ductile failure mechanisms. Comparison of the test results revealed that seawater had significant effect on the mechanical properties and surface morphology of the API X70 steel pipeline with respect to immersion time.Item Analysing the Physical Condition of Buildings: A Case Study of an Institution of Learning in Nigeria(School of Environmental International Conference (SETIC 2024), School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria, 2024-11-29) Abass, Abdulshakur; Ogunbode, Ezekiel Babatunde; Olubajo, Oluseun OlukemiBuildings depreciate with time and gradually perform less than they are expected. This is a concern for building owners and users. Research on depreciation of buildings tends to focus on identifying or categorising defects. However, investigations that examine the condition of public buildings that inhabit large and frequent users is limited. The aim of this research is to analyse the physical condition of public buildings in an institution of learning. This study adopts a case study approach involving physical observations and the condition rating of three buildings in an institution of learning in Nigeria. The results of the analysis showed that there were several similar defects on the walls, floors, roof, electrical and mechanical services. The results on the condition of the buildings showed average condition index values indicating that the buildings were in moderate condition with the laboratory in a better condition with an average condition rating of 0.58 and the offices with an average condition rating of 0.52 and the classes with an average condition rating of 0.44. The study argues that improving the condition or state of the buildings would lead to enhanced building performance.Item Analysis of Exhaust Gas Emissions from Gasoline engine-powered passenger vehicles in Nigeria(International Journal of Engineering Trends and Technology (IJETT), 2016-04-22) Nasir, .A.; Bori Ige; Shiru, .B. S.; Mohammed, .A.Emissions from vehicles in developing country constitute a large percentage of global emissions. The study involved the analysis of exhaust emissions using a gas analyser. The vehicles studied are mini buses and private vehicles of different model of carswhich constitute about 80% of the vehicles on Nigeria roads. It was established that the main types of exhaust gases from the automobiles were CO2, NO2, CO, and O2. The highest emission of CO2 was found to be 413.13 mg/m3 in the 2007 Peugeot car model. The highest exhaust gas emission of NOx, O2 and CO was discovered in the 1998 Honda passenger car model and recorded as 40.23 mg/m3, 45.41mg/m3 and 192.43 mg/m3respectively. The study of emissions will spur further studies on more efficient combustor design aimed at minimizing emissions.Item Assessing the Role of Librarians in Combating Health Misinformation during Pandemics in Minna Metropolis.(Department of Library & Information Science, Federal University Lokoja, Kogi State, 2024-12-19) Gana, Leah Yebo; Emeka, C.; Madaki, A. M.; Salubuyi, M. A.The adverse effects of misinformation on societal progress, particularly in the realm of health, are well-known. Librarians, as guardians of information, have vital role in disseminating accurate information to the public. This research paper explores the potential of the field of librarianship in countering health misinformation. The study examines existing literature on the societal role of librarians in combating misinformation. Additionally, interviews were conducted with all librarians from tertiary institutions in Minna metropolis to investigate their roles in disseminating factual information during the Covid-19 outbreak. The research explores the strategies employed by librarians to combat misinformation, the challenges they faced in this endeavour, and assesses the impact of these strategies on mitigating Covid-19 misinformation. The study delves into both the misinformation encountered by the community and the persisting beliefs in misinformation. Furthermore, it investigates the channels through which communities receive health information. The paper outlines effective initiatives within the Library and Information Systems (LIS) profession, emphasising recommendations for librarians to enhance their role in the digital age and contribute successfully to the field of public health. Seven librarians from all tertiary libraries in the Minna metropolis were interviewed. Additionally, One Hundred (100) residents from ten communities were randomly selected to fill out questionnaires to ascertain the impact tertiary libraries have on misinformation in the communities. Only librarians from health institutions attempted to educate the communities, with little impact felt.Item ASSESSMENT OF KNOWLEDGE ACQUIRED THROUGH TRAINING FOR JOB PERFORMANCE AMONG LIBRARIANS IN SELECTED LIBRARIES IN NORTH-CENTRAL, NIGERIA(Library Department, University of Nigeria, Nsukka., 2022-03) Goshie, Rhoda Wusa; Muthee, Daniel; Mutwiri, CarolineThe sufficiency of the service is dependent on the Librarians who are properly prepared and constantly learning .As a result, the quality of educational options and the capacity of personnel to take advantage of such chances on a regular basis are critical concerns. Librarians and more information employee need to continue to aspire for greatness in the discipline by constantly upgrading and improving their knowledge and competency as maintained by the IFLA code of ethics. Training of the librarians is a necessity which helps in assisting to carry out services that are acceptable. It is therefore paramount to study the assessment of the Knowledge for librarians and how it affects their job performance in the 21st century librarianship. A descriptive survey design was used for this study. The population of the study was 382 librarians from seven academic libraries in North- Central, Nigeria. Structured questionnaire was used to collect data for the investigation and the sampling technique used was census also known as total enumeration. The results shows that majority of the librarians have no adequate knowledge through training received and have not applied the knowledge for librarians effectively which leads to low performance on the job because most of these libraries do not have ICT knowledge such as; content curation and digital asset management . Nevertheless, they are not competent in applying the knowledge in discharging their duties. The paper concludes that Librarians should not focus on theoretical part of the profession but should emphasize on the application of knowledge of Librarianship on their job performance. The paper recommended that there should be provision of adequate training and retraining of librarian, adequate IT infrastructure should be provided and there should be standing policies for attending the trainings for effective job performance among librarians.Item Assessment of Plagiarism in Undergraduate Projects in the Department of Library and Information Technology, Federal University of Technology, Minna, Niger State(Nigerian Libraries: Journal of the Nigerian Library Association (NLA), 2017) Abduldayan, F.J.; Obaje, A.M.; Oyedum, G.U.The study examined students' plagiarism in undergraduate final year projects for the 2014/2015 academic session in the Department of Library and Information Technology, Federal University of Technology, Minna. Turnitin anti-plagiarism software was used in checking the similarity index and percentage of plagiarized content in the students’ projects. The acceptable benchmark for similarity index was 20% in line with the University policy. All the cases of plagiarism are treated as a case of examination misconduct by the University. The study utilized the analysis of Turnitin anti-plagiarism software as the method for determining the rate of plagiarism. The total population of 42 students for the 2014/2015 was considered, of which 31 (73.8%) successfully trained in their work and graduated with percentages ranging from 14% to 20% similarity indices. The study determined different tricks and methods adopted by students in manipulating the results of Turnitin in order to get the acceptable percentages. Findings revealed some of the challenges faced by students while using Turnitin for plagiarism check. These included students’ lack of paraphrasing skills, time constraints, and lack of continuous monitoring of students’ progress by faculty instructors. The study concluded that Turnitin has helped improve students’ work integrity among students and staff and has also ensured integrity in intellectual outputs emanating from the university. This has led to the increased research visibility and academic ranking of the Federal University of Technology, Minna on the Web. The study recommended that the University should encourage all students to start turning in their work early and not at the end of the project, as this would give them time to paraphrase their work before submission deadlines. The need for comprehensive training on how to paraphrase contents was also recommended.Item Attitude of library personnel towards preservation practices in academic libraries in Niger State, Nigeria(Journal of Library Services and Technologies, 6(1), 26 - 39, 2024, 2024-03-18) Fati Abubakar1 , G.

Therefore, email and mobile SMS services should be introduced that will distribute current information to library users on time.Item Case Hardening of Mild Steel Using Animal Bone, Charcoal and Sea Shells as Carburizers(Nigeria Journal of Engineering and Applied Sciences (NJEAS), FUT Minna, 2016-08-24) Muriana, .R. A.; Bori Ige; Abubakre, .O. K.; Abu, .J. O.; Sani, .C. E.Samples of Mild steel were treated in carburizing media which included animal bone, wood charcoal and sea shells at varied temperatures. Micro structural analyses, chemical composition tests, and mechanical properties tests were carried out on the carburized samples. Results indicated that the treated samples could be used in local production of some engineering components such as gears in place of imported components where hardness is considered together with toughness. The case hardening of the mild steel with charcoal granules gave the highest carburization of 0.905% on the surface with the highest hardness value of 69.3 HRA.Item Cavitational Deterioration of Diesel Power Plant Cylinder Liner(Journal of Mechanical and Energy Engineering, 2020-12-10) Bako, .S.; Nasir, .A.; Bori Ige; Musa, .N.The generating station in which diesel engine is used as a prime mover for generating electrical energy is known as diesel power plant. The cylinders liner are cylindrical component that are fixed inside the engine block. The function of the cylinder liners is to retain the working fluid and to guide the piston. Most diesel power plant uses wet-cylinder liners that are exposed to intensive cavitation. The paper aimed at studying the behavior of the cylinder liners that can lead to cavitation. The analysis involves, modeling and simulation in using Solidworks Software. The analysis shows that the cylinders are subjected to harmonic vibration resulting to momentary separation of the coolant from the cylinder wall, creating a pressure difference around the coolant surface which forms air bubbles. These bubbles explode at an extreme velocity. The explosion of these bubbles release surface energy known as cavitation. The energy hammers the cylinder liner surface thereby removing minute particles of metal from the surface of the vibrating cylinder leading to cavitational deterioration. The paper hereby calls on automotive designers to take critical measures in designing of; cylinder liner, water jacket and the entire cooling system, in order to control this phenomenon.Item Characterization and Management of Solid Waste Generated in Nasarawa LGA in Nasarawa State, Nigeria(Middle-East Journal of Scientific Research, 2016-01-18) Nasir, .A.; Kasimu, .U.; Bori Ige; Mohammed, .A.Solid wastes constitute a significant amount to environmental hazard in the society. The need to characterize solid wastes as an initial step to proffer solution to the problem of solid waste management cannot be over emphasized. In Nasarawa local government area (LGA) in Nasarawa state, the solid waste materials are characterized into six (6) different materials type which includes paper/cardboard, plastic food pack/plastic bottles, metal cans, food waste, polythene bags/polystyrene food pack and other combustible miscellaneous waste material. The waste characterization shows that Polythene bags/polystyrene food packs constitute the highest waste of 141.09 kg/day collected during the study period. This is followed by food waste with 130.37 kg/day. Plastic food pack/plastic bottles, metal cans, paper/cardboard and others has 64.64 kg/day, 59.39 kg/day, 53.51 kg/day and 29.15 kg/day respectively. The non-biodegradable wastes such as polythene bags/polystyrene food pack, plastic food pack/plastic bottles and metal cans constitute about 56 % (257 Kg/day) of the total waste collected during the study period. It is recommended that Nasarawa state waste management scheme should include the adoption of 3R’s methods scheme for reducing the biodegradable waste components and also employed for reducing the non-biodegradable waste components.Item Condition Surveys and Assessment of Buildings: A Review of Approaches Adopted(Proceedings of the 5th International Conference of School of Environmental (SETIC 2024), October, 2024, School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-11-07) Abass Abdulshakur; Olubajo Oluseun OlukemiBuilding condition surveys and assessment is increasingly becoming an important issue. This is because people spend a lot of time residing or working in buildings and knowledge of the condition of a building can reduce the likelihood of fatalities in the event of a disaster or building collapse. Research on building condition surveys and assessment tends to adopt varying approaches that seems to be contradicting. This study aims at examining the dominant research approaches on building condition surveys/assessment and to underline their assumptions, limitations and arguments. A review of the literature on condition surveys and assessment of building is executed. This literature is categorised into major themes, synthesised and the typical focus is challenged. The results show that four dominant approaches have been adopted in literature namely: model-based approach, fuzzy theory approach, condition index approach and the digital approach. The study argues that a combined or hybrid approach provides an alternative approach that will unearth reliable data on a building that can be triangulated or validated by comparing the different data on the condition of a building.Item Continuous Professional Development for Information Professionals Through The Nigerian Library Association(School of Science and Technology Education (SSTE), Federal University of Technology Minna, Niger State. Nigeria, 2017-10-03) Goshie, Rhoda Wusa; JImada, Aisha; Abdullahi Mahadi, Bilkisu; Aliyu, HadizaThis paper reviews the continuous professional development of information professionals through the Nigerian Library Association. Professional development is a lifelong learning and is indispensable for professional growth and instrumental for sustaining one’s competence. The library can also become more productive with new skills and knowledge acquired through professional development programs. The various professional development programs put in place by librarians include seminars, peer coaching, workshops, conferences, mentorship, courses, symposium real-time webcasts, and distance learning programs with interactive capabilities. The paper discusses the importance of professional development programs which includes updating knowledge and skills in existing and new areas of practice, keeping professional qualifications up-to-date, raising one’s profile through certifications and networking, making oneself more marketable to future employers, and obtaining new improved skills-making challenges tasks easier. The paper highlighted the problems associated with attending professional development which include; lack of interest, un- acceptance of submitted papers and lack of awareness.Item CUSTOMERS' INTENSION TO CHANGE MOBILE COMMUNICATION NETWORKS REGARDING QUALITY OF INFORMATION SERVICES PROVISION IN ZARIA METROPOLIS(I-manager's mobile Applications and Technologies, 2019-01) Hassan, Hadizatu; Goshie, Rhoda Wusa; JImada, Aisha; Oyewumi, Roseline; Amata, SadiyaThe study was undertaken to determine customers' intension to change mobile communication networks regarding quality of information services provision in Zaria metropolis. The study raised three research questions and answers were sought to them, among which are the types of information services provided by mobile communication network to customers in Zaria metropolis, customers satisfaction level, and their intension to change network providers regarding information service quality. Survey research method was adopted for the study and data was collected from the sample of 1,269 out of the total population study of 1534. The data were analyzed descriptively using frequency tables, percentage, mean, and mode. The study revealed that customers in Zaria metropolis are provided with a wide range of information services. It was also revealed that customers are partially satisfied with the overall services of call, SMS, Internet, and SIM card service in the entire networks. It is recommended that attention should be directed toward services with lower satisfaction by setting a target using a set of benchmark of ACSI and N.C.C standard of communication services, to serve as a guide for mobile network industries and telecommunication industries to raise the satisfaction level so as to maintain the market share, maintain and generate their customersItem DESIGN AND CONSTRUCTION OF A SMALL SOLAR POWERED AIR BLOWER FOR CHARCOAL FIRED FURNACE(JOURNAL OF THE NIGERIAN INSTITUTION OF MECHANICAL ENGINEERS, 2019-09-30) Muhammad, .A. B.; Nasir, .A.; Ayo, .S. A.; Bori IgeIn Nigeria almost all the local foundry shops rely on the manually operated blowers for supplying air for the combustion of the charcoals to melt metals. This manually operated blower has showed that much man-hour is required during firing as one laborer is dedicated to driving the rotary blower. This is labourous and reduces the rate of productivity of the enterprise. Therefore, it is necessary to find easier ways of supplying the energy required for the combustion so as to increase productivity. A solar powered blower is designed and constructed in this work. The performances of manually operated and solar powered air blowers are compared. Performance results of the manually operated air blower showed that it takes about 67 minutes and 42 minutes to melt 4kg of aluminum and zinc respectively. On the other hand, for the solar-powered air blower, it takes about 30 minutes and 17 minutes to melt 4kg of aluminum and zinc respectively. This indicates that the solar-powered air blower takes a shorter time to melt metals when compared with the manually operated air blower. In addition, the solar powered air blower eliminates the laborious aspect of supplying energy for melting metals and also reduces the times spent in metal melting process.Item Design and Construction of a Spring Stiffness Testing Machine(American Journal of Engineering Research (AJER), 2015) O. A. Olugboji; M. S. Abolarin; J. Y. Jiya; G. M. Alaya; C. K. AjaniA spring stiffness testing machine was produced which differentiates a good spring from bad one using hydraulic principle and locally sourced materials were used to produce at relative low cost and high efficiency. It also categories each spring by stiffness into one of several distinct categories based on its performance under test. This is to ensure that in the final assembly process, springs with similar performance characteristics are mated to ensure a better ride, more précised handling and improved overall vehicle or equipment performance. The construction of the machine involves basically the fabrication process which includes such operation as cutting, benching, welding, grinding, drilling, machining, casting and screw fastening. Taken into consideration under test, were types of compression springs with varying spring loading and their different displacement recorded at different pressures to compare their stiffness.
