ABSTRACT

The utilization of Public-Private Partnerships (PPP) procurement model for infrastructural development in Nigeria is being gradually embraced as a number of construction projects are being arranged through this model. This model is being applied more in countries like UK and China among others where drivers for the utilization of the system have been studied. Efforts at investigating critical factors for utilization of this procurement model have not received proper and adequate attention in Nigeria. Therefore, the objectives of the study were to identify the necessary factors for the utilisation of PPP procurement model in Nigeria and to assess the level of utilisation of PPP procurement model in Nigeria. Abuja was used as the study area because of its features as one of the metropolitan cities and Federal Capital Territory of Nigeria where building and engineering construction activities are at its peak, coupled with its soaring population which makes the provision of public infrastructure paramount for the benefits of its growing population. Factors evaluated in the study were those perceived to be critical to the peculiarity of the Nigerian construction industry. Respondents were built environment professionals in government ministries, departments, agencies and parastatals, public and private institutions, financiers of PPP arrangements, contractors and stakeholders involved in PPP projects. Data obtained were analysed using descriptive statistics. It was concluded from the findings that, the necessary factors considered for the utilization of PPP procurement model in Nigeria are accelerated projects development, facilitated creative and innovative approaches as well as technology transfer to local enterprises. Furthermore, the level of ultilisation of PPP procurement model has 57.1% of the respondents not involved in PPP procurement model. This may not be unconnected to the fact that the PPP procurement model is yet to be fully embraced for all infrastructure development purposes in Nigeria. It was therefore recommended that, the Infrastructure Concession Regulatory Commission (ICRC) and other relevant stakeholders should carry out sensitization campaign on the knowledge of the benefits of the model among professionals because PPP provides solutions such as finances, expertise and technological know-how to solving the problems encountered by the public sector in providing infrastructure.

ABSTRACT

The main thrust of this paper discussed the impact of militarization of the Niger Delta region of Nigeria. The Niger is Delta famous for crude oil production, but it is crises prone which results to the region been highly militarized. The militarization of the Niger Delta have provided the situation whereby there is a high military presence in the region, which leads to occasional confrontation between the armed forces and other para-military units in the Niger Delta with organized militant movements and dissenting element in communities that are also interested in benefiting from the resources in the region. The paper relied on secondary sources of data collection method. The results of findings show that the militarization of the Niger Delta have considerably adverse impacts on national security and economic stability, formation of armed groups, public service delivery, oil companies and the international community. Therefore, the paper recommended that government should adopt measures that encourage peaceful resolution of conflict in order to de-militarize Niger Delta for enhanced economic and socio-political development of the region.

ABSTRACT

This study sought to find out the effects of using Tiv language as medium of instruction on students’ achievement in Basic Science and Technology at Upper Basic Education in Katsina-Ala Local Government area of Benue state. The study was carried out in two secondary schools in Katsina-Ala Government area of Benue State. Two intact classes of the schools were assigned to experimental and control conditions. Experiment lasted for two weeks. It started with a pretest before treatment and a posttest after treatment using Basic science and Technology achievement test (BSAT). Mean and standard deviation were used to answer the research questions while analysis of covariance (ANCOVA) was the statistical tool to test the hypotheses. The result showed that students in experimental group who were taught in Tiv did not perform better than the control taught in English language and there was no significant difference in the achievement scores of male and female students taught in Tiv language. Based on the findings, the researcher recommended that the use of Tiv language alone in teaching of Basic science and Technology should be discourage, however, Basic Science and Technology teachers may use Tiv language as an instructional tool in teaching of Basic Science and Technology at Upper Basic Education in Katsina-Ala Local Government Area of Benue State.

ABSTRACT

Excessive workload is known for centuries for its eventual deleterious effect on health and performance and, as a result, on productivity and loss of man hours in various spheres of endeavour. It is also salient amongst the reasons many tertiary institutions of learning fall short of standards required for accreditation by various accrediting commissions with inadequate numbers of qualified teachers assigned to ever increasing numbers of yearly student admissions which, in turn, is designed to satisfy the educational needs of a geometrically expanding population. In a number of institutions, threats to accreditation in one or more disciplines usually gives rise to frantic curbing of number student admissions over several years t improve facility. This is a critical look at the effect of excessive teacher workload on the quality of education.

Study Objective/Setting: To determine the influence of student numbers and classes taken by each lecturer on the quality and academic performance of students at our academic health sciences institution.

Method: A five – year retrospective study of students’ academic performance against numbers of students under the tutelage of the teachers. We studied three clinical levels taught by the Department of Surgery of our tertiary academic medical sciences centre from 2008/2009 to 2012/2013 academic sessions. Outcomes were documented as scores from the examinations conducted over the period of five (5) academic sessions.

Results: Between 2008/09 and 2012/13 academic sessions, there was58.6% and 50.4% progressive reduction of 400 level and 600 level medical students, respectively, taught by 19 teachers over those sessions. This was reflected as 55.2% reduction in teachers’ workload, between 2008/09 and 2012/13, as well as 22.4% and 21.6% improvement in academic scores at both 400 Level and 600 Level medicine classes, respectively. Thus, there is a strong positive linear correlation between teachers’ workload and the performance scores of students at each academic level. (Pearson’s r = 0.78).

Conclusion: There is, incontrovertibly, the need to establish more standard accredited higher institutions of learning to accommodate the teeming numbers of young prospective graduates, as well, reduce the workload (pressure of work) on the teachers. These will serve to reduce the number of students per teacher, foster student – teacher educational interractions, reduce the demand on tenuous teaching facility in resource-limited settings and improve the quality of the nation’s young workforce graduating each session from institutions of higher learning.

ABSTRACT

The study assessed sweet orange production and its post-harvest losses among farmers in North-Eastern Zone of Benue State, Nigeria.Specifically, the objectives of the study were to: find out the quantity of oranges produced by farmers, examine the extent of post-harvest losses of orange and explore possible ways to reduce post-harvest losses of orange in the area. One hypothesis was formulated to authenticate the result of the study. The study adopted duffusionist theory. Cross-sectional design was employed. A sample size of 313 respondents was drawn from a population of 1442 registered orange farmers using multi-stage sampling technique. The instruments for data collection were questionnaire, KII and FGD. Data collected through these methods were analysed using descriptive statistics to address research objectives, while ANOVA was used to test the hypothesis at 0.05 level of significance. Findings revealed that most orange plantations in the study area were within one hectare and less than a hectare. The cultivars grown were mostly Ibadan Sweet and Valencia. An average of 22,164.6bags of oranges were harvested, 16,672.3bags were sold while 5,492.3bags of oranges were lost. Findings revealed that the extent to which post-harvest losses of orange occurred in the area was as high as 21-30 per cent. These losses were noticed to occur in all the post-harvest stages of orange. However, plucking and bagging (31% and above) were the principal stages of post-harvest losses of orange. The study therefore recommended awareness and sensitisation creation on post-harvest losses of orange among farmers, change in settlement pattern among the people of the study area, farmers before harvesting the fruits should endeavour to spread cushions around the tree canopies and harvest at the appropriate time of the day, possibly when the grounds are dry, among other recommendations as strategies to increase orange plantations and reduce post-harvest losses in the area.

ABSTRACT

The objectives of this research are to extract the air-dried stem bark (500g) of citrus aurantifolia with methanol using cold infusion (maceration) technique, partition the extract  with solvents of graded polarities (n-hexane, ethyl acetate, n-butanol suspended in water) and phytochemically screened and fractionate and purify the n-butanol partitioned portion using a combination of column and thin layer chromatographyand finally subject the possible pure fraction(s)  to gas chromatography and mass spectrometry (GC-MS) analysis. The methanol crude extract yield 14.90% w/w dark green in colour, gummy in texture. the n-hexane partitioned portion yield 0.44% w/w  light green in colour oily paste texture, ethylacetate partitioned portion yield 5.32% w/w  dark brown in colour, gummy in texture, while n-butanol yield 21.04%w/w, brown in colour, gummy in texture and finally aqueous partitioned portion yield 52.08% w/w  brown in colour power in texture respectively. The presence of metabolites such as carbohydrates, cardiac-glycosides, terpeniods, flavonoids, tannins and phlobatannins were recorded in the methanol crude extract while, anthraquinones, alkaloids and saponins were not detected in methanol crude stem bark extract. Whereas cardiac-glycosides, terpeniods and flavonoids were present in n-hexane portion and n-butanol portion but carbohydrates, anthraquinones, tannins, saponins, phlobatannins and alkaloids were not found in both of the portions.. The purification of compounds was done by using a combination of column and thin layer chromatography techniques. The n-butanol partitioned portion was subjected column chromatography after, rerunning, recombination and pooling four compounds, coded Ca1, Ca2, Ca3 and Ca4 were obtained. The melting points were sharp and uncorrected. In gas chromatography and mass spectrometry (GC-MS) analysis of compound of sample Ca1 fourteen compounds were identified by comparison with the library of NIST. Among the compounds, were found to be 3, 5, 9-Trioza-5-Phosphaheptacos-18-en-1-aminium, Pentacosanoic acid, Oleic acid, 7, 8-Epoxylanostan-11-ol. Analysis of Compound of sample Ca2  shows that only one compound was identified by comparison with the library of NIST. The compound was found to be 3H-Cycloocta[c]pyran-3-one. Analysis of Compound of sample Ca3 shows eight compounds were identified by comparison with the library of NIST. Among the compounds were found to be 1, 3-Dioxane, Pregn-5-en-20-one, 9-Octadecenoic acid, Heptadecanoic acid, Epoxylanostan-11-ol. Analysis of Compound of sample Ca4  shows that eight compounds were identified by comparison with the library of NIST. Among the compounds were found to be Glycidol stearate, Andrast-4-ene-3-one, Octadecanoic acid, Dihydromorphine.. The dihydromorphine which believed to be a reduced formed of morphine with a molecular formula of C17H21NO3. It has been reported thatthe 7, 8-double bond of morphine also is not required for analgesic activity as indicated by the relative analgesic potency of dihydromorphine. Also, oxidation of the 6-OH of dihydromorphine to yield hydromorphone further increases activity.

ABSTRACT

In this study, the potential of limestone as an adsorbent of different particle sizes for the removal of arsenic from drinking water was investigated. Effects of various operating parameters such as particle size, contact time and adsorbent dosage ere studied using batch adsorption studies. X-ray fluorescence (XRF) was used to certify the mineral composition of limestone. This method shows maximum removal of arsenic 98.4 % under the following operating conditions: contact time 10 min, adsorbent dosage 2 g, particle size 2 µm and temperature 28 oC. Pseudo-first and pseudo-second-order kinetic models were employed to elucidate the adsorption behaviour of the system. The result of the adsorption process showed a poor correlation value with the pseudo-second-order model compared to the pseudo-first-order. This designates that the rate-determining steps in the adsorption of arsenic could be physical adsorption processes.
