ABSTRACT The emergence of Information and communication technologies (ICTs), and e-Government, has made it possible to improve efficiency and effectiveness of internal administration within government and to re-locate government service from government offices to locations closer to the citizens. However, in its effort to have ICT systems that make these services available to citizens, most of the system projects have not been sustainable as the systems do not last or achieve the objective th...
ABSTRACT Rice (Oryza sativa L.) is the main staple food for more than half of the world’s population. Improving cooking and eating quality of rice is one of the important objectives of many plant breeding programs. Aroma and cooked kernel elongation are two critical parameters that determine the market value, cooking and eating qualities of rice. The objective of this study was to evaluate the phenotypic and genetic diversity of thirteen (13) Oryza sativa L. populations from Ke...

The research designs adopted for this study are ex-post facto and survey which was conducted using a well structured questionnaire to obtain information. The sampling designs adopted are simple random sampling for questionnaire distribution and judgemental sampling for the selection of three r...
ABSTRACT This study calibrates an intercity travel demand model which uses the principal structural variables that have been identified in the literature. It uses a robust econometric method which has been little applied in the sphere of land transport in Nigeria. This research develops an urban public travel demand model for 19 directional O-D city-pair network originating from Owerri Urban. Using revealed preference data from the period of 2014 to 2016 which was filtered into 207 observati...
ABSTRACT Dissatisfaction expressed by clients on the poor performance and level of service received from construction industry operators especially professionals gave birth to the need for this study. This study examined the measurement, valuation and payment for bills of quantities items consistently not executed by contractors in Nigeria. Primary data for this study was obtained from questionnaire randomly administered to Quantity Surveyors at a conference in 2008 and secondary data obtain...
ABSTRACT This research is geared toward assessing the extent cost of retaining an aging server hardware has affected the transition to current server hardware in a developing country like Nigeria. Primary data were the major source of data for the study. The collected data were subjected to multiple regression analysis. The study found that software update, Random Access Memory (RAM) maintenance, hard disk maintenance and power/ cooling costs have significant cost impact on aging server hard...
ABSTRACT This research was conducted to determine if quality assurance and its strategies are effective for successful project execution in the construction industries. Data was obtained from both primary and secondary sources. The primary sources consisted of questionnaires and observations while the secondary data consisted of texts, websites and journals. Percentages were used to analyze data and analysis of variance (ANOVA) was adopted in testing hypothesis. Among the major result of dat...
ABSTRACT The introduction of Computer into Pension Management System has greatly improved the retrieval of files in Pension department. This is made possible due to the enormous capabilities of computers. In order to help these capabilities of information, every system or organization that is non-computerized is now being computerized. Pension is a periodic payment made to public servants who have completed their service usually between 10 to 35 years. The manual process refers to the writin...
ABSTRACT Studies on the biosorption potentials of Zea mays cobs and Musa paradisiaca peels in the treatment of waste effluent from paint industry, was carried out. Standard laboratory procedures using 400 ml of the effluent were adopted to assess the values of Pb, Fe, Cland PO4, BOD and TDS at pH 6.7 and pH 10.0 before and after treatment of the effluent with 1g and 3g of pulverized corn cobs and plantain peels. Standard procedures were adopted for the phytochemical screening of the biosorbe...
ABSTRACT This research focused on assessing the port performance: the queuing theory approach using Apapa port complex (APC) as the case study. The research was designed and carried out to answer among others the following questions: to assess the level of vessel turnaround time, traffic intensity, the waiting time of calling vessels at the port? Also, to determine the probability of vessel queuing on arrival at the port? To answer these questions only primary means of data collection were u...
ABSTRACT This study assessed the productivity and efficiency of airports in Nigeria employing the method of Data Envelopment Analysis (DEA).Two variants of DEA models were estimated and their outputs compared in order to enhance the robustness of the study. These models include the one based on Constant Returns to Scale (CRS) to characterise the input-output combinations and that based on Variable Returns to Scale (VRS). It is sometimes argued that DEA models generally tend to overestimate e...
ABSTRACT This project is carried out with the aim of x-raying the difficulties experienced by private developers in providing commercial housing for the people of Bayelsa State. The primary data for the study were captured through structured questionnaires. The data were analyzed using Pie chart distribution and analysis of variance statistical methods. The analyzed data were used to test the postulated hypothesis. The results showed that cost of site preparation and the terrain of the state...
ABSTRACT Biofertilizers offer commercially feasible and environmentally sound means for supplementing nutrient supply to crops. The basic problem in acquiring quality rhizobia biofertilizers is the low number of efficient cells. The major limitations affecting the quality of rhizobia biofertilizers are; short storage duration, unavailability of appropriate carrier materials, and susceptibility to high temperature. The present study evaluated the effects of selected carrier materials and stora...
ABSTRACT This study shows the effect of changes in GDP, population, foreign trade and seaport access corridors of ECOWAS member countries, especially the littoral States, on the growth of freight volumes of their respective economies. The primary aim of the research is to develop a short sea shipping model for the ECOWAS sub-region, with the objective of reducing the cost per transported unit within the sub-region and predicting the growth of short sea shipping freight in ECOWAS economies. T...
