No full textPhysical properties of neem (Azadirachta indica) seeds and kernels relevant in the design of processing machineries
No full textThis study was undertaken to determine some physical properties of neem seeds and kernels such as axial dimensions, true density, bulk density, surface area, sphericity, moisture content, coefficient of friction, angle of repose and porosity that are relevant in the design of processing machineries. Results shows that the seeds and kernels have major, intermediate and minor diameter values of 13.641.15 mm, 6.800.41 mm and 5.540.44 mm and 9.321.13 mm, 4.320.63 mm and 3.380.35 mm respectively. The true density, bulk density, surface areas and the sphericity determined were 379.0015.16 kg/m3, 39.2930.001 kg/m3, 169.9331.15 mm2, 0.640.043 for the seed while for the kernel were 930.038.53 kg/m3, 534.8910.99 kg/m3, 70.6313.98 mm2, 0.610.044 respectively at an average moisture content of 13.80 % for the seed and 11.9 % for the kernel on wet basis. The coefficient of friction determined on three different structural surfaces namely plywood, glass and mild steel for the seeds were 0.38, 0.42 and 0.33 respectively at an angle of repose of 34.52o while that of the kernels were 0.49, 0.56 and 0.43 respectively at an angle of repose of 42.47°. The mean porosity obtained for the seed and kernel were 89.62 % and 42.47 % respectively
Effect of Density on the Natural Resistance of Ten Selected Nigerian Wood Species to Subterranean Termites
No full textThe effect of density on the natural resistanceof ten selected Nigerian wood species to subterraneantermites was investigated. Wood samples obtainedfrom mixed-conversion boards were used such that thesamples contained both sapwood and the heartwood.They were sawn to 35×35×450mm stake and dried at103 ±20C till a constant weight was achieved. Densityof the selected wood species was determined. Basedon the observed average density, the wood specieswere classified into high, medium or low density.Graveyard test method was used to assess the naturalresistance of the samples on a site dominated byMacrotermes sybhylinus, a family of subterraneantermites. Weekly visual observations of the stakeswere taken as specified in ASTM D3345-80 Standardsfor 24 weeks. The wood samples were withdrawn atthe 24th week of exposure to termites and weight lossdue to termites’ attack was estimated. Result obtainedshowed the relationship between wood density, weightloss and the ASTM ratings. A strong but negativecorrelation (R2= -0.70) existed between weight lossand wood density while a strong positive correlation(R2=0.83) existed between ASTM values and wooddensity. These results indicated that wood species inthe high density class had a better resistance totermites’ attack. The influence of mixed conversion onthe resistance of wood species to subterraneantermites was also reported, since it is the mostcommon method of conversion in the Nigeriansawmills. The sapwood of high density species are notdurable as revealed in the study thus the preservativetreatment is imperative for long service-life
Boko Haram Insurgency and Nigeria’s Foreign Policy in the Lake Chad Region
No full textThis paper examined the implications of Boko Haram insurgency on Nigeria’s foreign policy in the Lake Chad region. The study purposely evaluated how Nigeria’s foreign policy have been jeopardized, disrupted and negatively affected by the activities of Boko Haram insurgency and terrorism in the region. The study is purely qualitative in nature and used secondary data. The data were analyzed thematically through content analysis. The linkage theory was adopted in the analysis of this work. The findings of this study revealed that the emergence of Boko Haram insurgency and terrorist acts plummeted Nigeria’s relevance in the Lake Chad region and the international community. The insurgents’ activities led to the displacement of people from Borno, Yobe and Adamawa states in the form of Internally Displaced Persons (IDPs) fleeing to safer havens within the nation and refugees were fleeing to neighbouring countries like Niger, Chad and Cameroun in the region. It is therefore recommended among others that, Nigerian government should improve the socioeconomic conditions of Nigerians to dissuade them from all forms of recruitment to Boko Haram sect. Nigerian government should deepen collaboration with the governments of Member States of the Lake Chad Basin Commission to devise strategies to meaningfully address the Boko Haram insurgency through military and non-military approaches
Availability of Instructional Materials on Students’ Academic Performance in Senior Secondary Schools in Maiduguri Metropolis, Borno State
No full textThis study examined the availability of instructional materials and students’ academic performance in senior secondary schools, Maiduguri Metropolis, Borno State, Nigeria. Two (2) objectives and a null hypothesis were used to determine the availability of instructional materials and students’ academic performance in senior secondary schools in Borno state. Survey and Correlational design were used. The total population of the study was 1,236 teachers and 10,349 students out of which 371 teachers and 3,105 students were sampled through simple random sampling. SSCE results for five consecutive years of the 2014-2018 academic sessions were obtained for the study. Checklist and Pro-forma were used for data collection. Data collected were analyzed using Pearson Product Moment Correlation coefficient, frequency and percentage at 0.05 level of significance. The study revealed a significant relationship between availability of instructional materials and students’ academic performance in senior secondary schools in Maiduguri Metropolis. The study also found that the instructional materials for teaching and learning are available. Based on the findings, it was recommended that government and other stakeholders should continue to support schools in the state with the necessary instructional materials needed for teaching and learning and School administration should emphasize the use of instructional materials to make learning easier
A Bi-Model Machine Learning Driven Application for Diagnosing the Dominant Illness among Typical Nigerian University Students
No full textThe implementation and deployment of machine learning models for the diagnosis of dominant illnesses among students require significant investment in technology and infrastructure, which is among the barriers for healthcare organizations with limited resources. In order to increase its adoption, this research suggests the creation of a Bi-Model Machine Learning Driven Application that will enable university students to get diagnosed with common ailments. The plan is to apply a high-level model using a hybrid methodology that combines the development of Machine Learning Models with Agile Software Development. In order to do this specifically, Python was used to implement exploratory data analysis, classification, and regression models, as they have proven to be highly effective in both diagnosing the primary illness and predicting the length of hospital stay. The bi-model were built with four different algorithms each, so as to adopt the ones with best performance for the deployment. The model built with Gradient Boosting Classifier has 100% accuracy, 100% precision, 100% recall as compared to other three algorithms through three repeated training of the model. On the prediction of admission duration task, Gradient Boost Regression works best, and this is because it has the least Root Mean Square Error of 0.57 and Mean Absolute Error to be 0.423 among other compared three algorithms, as measured. This was achieved through the use of fresh localized dataset from the Federal University Lokoja Health Center, which was pre-processed, and stored in the file manager/internal storage for visualization and modelling. Furthermore, the completed models was deployed to a web application using flask and Mysql Lite Database. In the end, the application reduced human error in diagnosis and care management of the student population while they are pursuing their education by enabling evidence-based awareness, educated public health policy, and individualized treatment
