Abstract: The persistent escalation of cost of both building and infrastructural projects in Nigeria is alarming. In other to improve upon the existing scenario, this study investigated and evaluated determinants of construction cost in Nigeria. The objectives of the study include: Comparative cost analysis of construction projects in Nigeria with that of some African countries, evaluation of construction cost matrix and suggestion to improve on existing scenario. Data obtained through stratified probabilistic sampling technique from 50 Nigerian Quantity Surveyors through structured questionnaire were analyzed quantitatively and the findings of the study revealed that high cost of construction materials, inflation, monopolistic market for construction materials, deliberate inflation of contract sum and kick back syndrome are major determinants of cost of construction in Nigeria. The study concluded that to curb this menace, measures outlined in the study must be implemented.

ABSTRACT

It has been argued in recent times that the quantity of crude oil export increases as the year increases as well as production of crude oil, yet Nigerian economy decreases as the year increases. Hence, there is need to evaluate or build a model in order to help policy makers forecast the quantity of crude oil export in Nigeria. The aim of this paper is to fit an appropriate model to the crude oil export in Nigeria. Therefore, we estimated the autoregressive integrated moving averages: ARIMA(1,1,1), ARIMA(2,11), ARIMA(1,12), ARIMA(2,1,2) SARIMA (1,1,1) (1,1,1)12, SARIMA(1,1,1)(2,1,1)24 and their various autocorrelation function (ACF) and partial autocorrelation function (PACF). Based on Ljung-Box statistics, the ACF and PACF, we choose SARIMA(1,1,1)(2,1,1)24 as the appropriate model. This model has also, the least mean squared Error (MSE). Therefore we forecasted Nigeria’s crude oil export with SARIMA(1,1,1)(2,1,1)24; the results indicate that Nigeria crude oil export will decrease in the long run therefore there is need for diversification of Nigeria economy.

ABSTRACT

Mathematical models have been used to provide an explicit framework for understanding malaria transmission dynamics in human population for over 100 years, with the disease still thriving and threatening to be a major source of death and disability due to changed environmental and socio- economic conditions. In recent years, many more of the numerical methods were used to solve a wide range of mathematical, physical, and engineering problems both linear and non-linear. In this work, we used the Homotopy Perturbation Method (HPM) to obtain the analytic solution of the differential equations of the (SIR-SI) mathematical model and we apply the Bellman and Cooke’s theorem of stability to verify the stability of the model at equilibrium state. This work confirms the power, simplicity and efficacy of the method, also this method is a suitable method for solving any partial differential equations or system of partial differential equations as well.

ABSTRACT

A field experiment was carried out during the rainy seasons of 2005, 2006 and 2007   at the Abubakar Tafawa Balewa University Teaching and Research Farm, Bauchi, to study sowing date on the growth and yield of sesame (Sesamum indicum L.).  The treatments consisted of three sowing dates which were, 30/6/, 15/7 and 30/7. These treatments were laid out into a Randomized Complete Block Design (RCBD). From results obtained and analysed it indicated Sowing sesame   on 15th and 30th July produced heavier seeds than when the crops are sown on 30th June,  there was  no clear distinction among the different sowing dates on number of capsules per plant.  Effect of Sowing date sesame yield and yield related characters revealed sowing date having significant effect on sesame number of capsules per plant throughout the period of the investigation Significantly heaviest 1000(g) seed weight was observed in crops sown on July 15 & 30 (2.03, 2.03), while significantly highest seed yield(kg/ga)  was observed in crops sown on 30-6, in 2006. Cropping season, hence sesame producers in the study area advised to sesame their sesame early as soon as the rain establishes.

ABSTRACT

The research was experimented to study the economic and performance of broiler finisher on vital feed and graded levels of some agro-by products. The experimental birds used were sixty (60) in number aged five weeks, were assigned to four treatments in a completely randomized design replicated thrice with fifteen (15) birds per treatment. Diet T1, was a control diet of 100% VF while diets T2, T3 and T4 were mixed with some agro-by products of 40% SC, 40% CHP and 40% CH respectively. The findings shows that the total final, average and total daily body weight were significant at (p>0.01). While average daily body weights, total daily feed intake average daily feed intake, and feed conversion ratio were significant at (p>0.05). Then the cost savings (Nkg) in which the Economic analysis was purposely experimented was best on T4, T3 and T2 with (N330kg), (N290/kg) and (N250%/kg) respectively, and poorest on control diet with (N0.00k/kg). The carcass characteristics were significant (p>0.05) on carcass weight, heads weight, sharisk weight and gizards weight while other are not significant (p>0.05%). Agro-by products such as cowpea husk and sorghum chaft could be incorporated into poultry feeds to reduce cost of poultry feeds.

ABSTRACT

With over 200 million people in Nigeria, feeding and meeting their nutritional needs is not only challenging for the nation but crucial and critical for the quality and quantity of human resource available for sustainable food security.  If Nigeria is to meet the Sustainable Development Goal 2 of Zero Hunger and Goal 3 of Good Health and well Being; the issue of food security thus becomes inevitable because food crisis (food insecurity) has become a persistently volatile problem in the country recently with Nigeria skyrocketing food importation. Like many other developing countries, Nigeria has experienced a shortage of food supplies due to economic instability, severe drought, flood and persistent conflicts etc. To feed the future population of Nigeria which the United Nations has projected to reach 398 million in 2050, there is a need to examine the food security apparatus of the nation which will no doubt impact on the nation’s sustainable development. Thus, this paper x-rays the place of food security: Issues and challenges. The paper recommends among others the need for improvement in technology, ensured security of lives and property of farmers and appropriate policy and political will by the government so as to enhance increased domestic production and reduced importation of food.

ABSTRACT

The research was a study on adoption and utilization of new media technology among rural farmers in Gidan-Kwano community of Minna, Niger State. The objective was to find out the level of exposure to digital media use in their occupation, their awareness about the importance of the technology, their readiness to adopt the technology amongst others. Survey was adopted while questionnaire and semi-structured interview were the research instruments used. The population of the study was 4000 farmers. Krejcie and Morgan table for sample size determination was used to derive a sample size of 351. Data were analyzed using descriptive statistics and Yin’s thematic explanation model. Findings revealed that the major hindrance to the adoption and utilization of new media by top farmers in the study area is that of illiteracy and poverty. This aligned with the reason behind their ignorance of the importance of the technology hence couldn’t apply it. Furthermore, some farmers who adopted the use were not comfortable with it due technical challenges in operating the device and other challenges encountered. The study further confirm that findings conducted by several scholars in this area which is illiteracy, poverty, poor power supply, poor network by service providers amongst others is true and therefore, opined that until the findings and recommendations made by scholars are taken seriously by government and relevant institutions, organizations and agencies, researches will continue to move in circles without any significant advancement.

ABSTRACT

Geophysical investigation involving the use of vertical electrical sounding (VES) on  grid-A part of Felele campus, Federal University Lokoja, Nigeria with  objectives  to delineating depth to fresh basement, fractured zones in the study area for potential groundwater exploration within the crystalline basement rocks. The area is underlain by the Crystalline Basement rocks composed of granite gneiss, quartzite and intrusions.  PASI Terrameter was used and the symmetrical Schlumberger configuration adopted. A total of four (4) Vertical Electrical Sounding (VES) stations were established. Preliminary input data from the field were inputed into the WINRESIST software to generate real resistivities and depths to geoelectric layers. Three (3) geoelectric layers were interpreted, the first layer is the top soil made up of resistivity values ranging from 141 Ωm – 486.1 Ωm and depth to weathered basement of 1.2-2.5m. It is inferred that this layer does not consist of the same material across the entire length of the profile. The second layer is made up of resistivity values ranging from 37.9Ωm to 85.6Ωm and depth to fresh basement of 11.2 – 16.1m. Its inferred to composed mostly of fractured and unconsolidated rocks, loose gravel, sandy soil and clayey. The resistivity value within this layer indicates that is it good for groundwater exploration and the third layer has the highest resistivity values ranging from 821.2 Ωm – 2695Ωm with an infinite depth. It’s entirely composed of fresh basement rock which is possibly of the gneissic suite.

THE TRADITIONAL SETTLEMENT PATTERNS IN THE JOS METROPOLIS AND THE CHALLENGES TO THE “GREATER JOS MASTER PLAN” OF THE 21ST CENTURY.

ABSTRACT

Before its growth to urban status, where today, is called the Jos metropolis had been settled by indigenous populations (Berom, Anaguta, Rukuba and Afizere). As elsewhere in the Middle Belt area, Jos was dotted here and there with traditional settlements linking one settlement to another by narrow footpaths. The advent of colonialism and attendant mining activities introduced into the Jos area some semblance of modern settlement, with wider motorable roads. However, this development had continued but at a “snail pace”. The problem today is how a truly modern pattern of settlement can be developed, to replace the stubbornly surviving traditional settlement pattern. The problem has lingered through the ages with one master plan to another, with just some minimal successes. This has triggered in the following questions: what has been the actual problem besetting the implementation of the Greater Jos Master Plan? What does the Greater Jos Master Plan involve? What has been the reaction of the indigenous populations to the plan? These and many more constitute the focus of this paper. The method adopted here involved the use of questionnaire, administered to selected elders of the Jos metropolis and staff of the Ministry of Land Survey and Town Planning. Responses were matched against a few existing written reports for objective appreciation of the problem and what suggestions can be made. The findings showed that in addition to reluctance to pay compensation, there has never been a programme of enlightenment.

ABSTRACT

Underlying the selection of contractors is the use of contractor pre-qualification data in order to identify the most qualified contractor. This research was aimed at evaluating the criteria for selecting contractors for construction projects on the basis of their order of importance and ease of usage respectively. Primary data was elicited from a sample size of 77 clients, 83 consultants and 65 contractors spread across the six states of North-Central Nigeria. Frequency distribution tables, percentiles, mean item score, and analysis of variance constitute the tools for data analysis. The study revealed that the major rationale for stakeholders’ adoption of contractor selection criteria is to meet clients’ objectives. While technical competence constitutes a major driver for contractor selection, the study unveiled that only financial reputation exhibits statistical significance with respect to ease of use towards selecting competent contractors in the study area. It was recommended that stakeholders should pay serious attention to technical competence and the quality of past performance which are essential determinants for contractor pre-qualification; reason being that a technically competent contractor with track record of quality project delivery will automatically pass the assessments tests with respect to indices of financial reputation and managerial capacity.
