ABSTRACT

Computers have simplified our working life to be more efficient and productive, for example, communication can be done through mail and instant messaging, presentation can be shared through Netmeetings and meeting minutes can be stored in workspace or shared drives. Computers, especially notebooks and laptops  are very synonymous with mobile lifestyles as it is very convenient. LAN and wireless facilities which allow users to access borderless information at anywhere and at any time, turn the computer into a necessity rather than a luxury. However these gadgets sometimes malfunction and not every computer owner is a troubleshooter or able to find out the root cause of the malfunction. This is where the expert system is needed for help to any user as a first aid approach to identifying and solving the problem. This paper presents one of such expert system designs and is limited to PC hardware maintenance and troubleshooting covering to the Monitor, Hard drive, Keyboard, Mouse, Audio device, and Missing/Lost Documents via a rule base diagnostic system using PHP

ABSTRACT

In the present paper, the boundary layer flow of viscous incompressible and electrically conducting fluid past a stretching plate has been considered. The boundary value problem governing the flow has been solved as initial value problem for velocity function using shooting method first, then Runge-Kutta method of order four. The values of velocity function so obtained have been used in the solution of heat transfer problem. The results have been discussed graphically.
Keywords: Boundary layer equation, Stretching plate, heat transfer.

ABSTRACT

The IPS 42 ionosonde was used to collect data at Ouagadougou, Burkina Faso (12.40N, 1.50W, dip 5.90N), an equatorial station in West Africa, using IPS 42 ionosonde, were used for this work. Ionograms for years of high solar activity [1990 (Rz=143) and 1991(Rz=146)] were analysed. The parameters used for this study are the peak electron density (NmF2), height of occurrence (hmF2) and the slab thickness (TF2)  of the F2 layer of the ionosphere respectively; as well as the IRI (international reference ionosphere) bottom side profile parameter B0, shape parameter B1, for the F2 region. The simultaneous effects of geomagnetic storms on these parameters were investigated.

ABSTRACT

The levels of trace metals were determined in the Moringa oleifera (drumstick). The leave, bark and root part samples of Moringa oleifera, located in Kazaure local government area of Jigawa state, Nigeria were analyzed for trace metals using atomic absorption spectrophotometer(AAS). Generally, the plant accumulate metals in the order Fe > Pb > Cr > Cd. The root samples concentrated the highest level of all the metals. The result revealed the accumulated amount of trace metals in leave sample as 0.053mg/kg(Cr), 0.160mg/kg(Pb), 0.573mg/kg(Fe) and 0.035mg/kg(Cd), in the bark sample as 0.199mg/kg(Cr), 0.293mg/kg(Pb), 3.244mg/kg(Fe) and 0.187mg/kg(Cd) and in the root sample as 0.355mg/kg(Cr), 0.393mg/kg(Pb), 10.374mg/kg(Fe) and 0.259mg/kg(Cd).  The range of metal concentration determined in Moringa oleifera   as a whole is Cr (0.05 – 0.35mg/kg), Pb (0.16 – 0.39 mg/kg), Fe (0.57 – 10.37 mg/kg), and Cd (0.04 – 0.26 mg/kg). The relative high concentration of the lead over chromium is attributable to vehicular emission experienced in the studied area. Levels of metals in the Moringa oleifera sample were generally below the WHO and FAO maximum permissive limits. The values so detected in this study are within safe levels, hence the consumption of Moringa oleifera amidst the inhabitant of Kazaure poses no immediate health hazards.

ABSTRACT

In this twenty –first century, budgets, as an integral component of constitutional democracy, have become a prerequisite for good governance. Apart from promoting transparency and accountability in public fund management, budgeting is also a fiscal instrument for self-assessment. Post budget review activities are used to gauge overall performance. This places a lot of emphasis on the need to ensure its proper implementation. Nigeria has intimidating, top class financial experts/technocrats, who have drafted some of the best annual budgets in the whole of sub-Saharan Africa. Unfortunately, this has not driven Nigeria up the ladder of development. Poor budget implementation has resulted in a form of public governance bedeviled by unemployment, poor public infrastructures, the lack of public accountability etc. Consequently, the cost of doing business in Nigeria has been on the increase. This has discouraged investors and limited the availability of foreign capital for a sustainable national development.  The major objective of the study was to analyze the relationship between budget implementation and good governance in Nigeria, using the former to enhance the latter. Data collected from secondary sources were critically analyzed, using indicators such as economic efficiency, technical efficiency and operational efficiency. Analysis showed that certain factors, such as gross corruption, lack of oversight function, delays in implementation, unrealistic goals etc have not enabled budget implementation to maximize Good Governance in Nigeria. To remedy the situation, certain recommendations were proffered to bridge the gaps.

Keywords- Budget, Implementation, Good Governance, Development, Efficiency, Effectiveness.

ABSTRACT

The study examines the effects of manager’s managerial skills on staff efficiency and effectiveness in organization. Recent evidence confirms that despite more than a decades scholarly available strategies of managerial skills to enhance staff efficiency and organizational effectiveness and productivity, many organizations in various countries currently experiencing managerial skills problems led to organizational under productivity and staff inefficiency and ineffectiveness. The total population of sixty (60) staff were used as data sources. Administration of self-designed questionnaire was also used to gather information. The data collected were subjected for appropriate statistical technique of Pearson Product Moment (PPM) (correlation coefficient r). The result obtained from the analysis showed that there existed a strong relationship between manager’s managerial skills and staffs efficiency and effectiveness in organization. The study also emphasize the needs for managers to acquire basic skills approach such as technical, human, conceptual, diagnostics and communication skills  through education, experience and mentor relationship. This paper further appeal for organizational manager’s to learn the roles and functions necessary to practice for organizational success. On the basis of this finding, several recommendations were highlighted for further research.

ABSTRACT

The history of the Nigerian Pensions administration dates back to the 1950s.The Pension Reforms Act of 2004 brought into limelight the new pension scheme in Nigeria which is a defined contributory scheme unlike the old scheme which was largely defined benefits. Although the new scheme is adjudged to be better than the old scheme in that it is  expected to help remedy the deficiencies and inadequacies prevalent in the old scheme, it is advocated that only proper coordination, supervision and regulation of the pension industry in Nigeria will make the new pension scheme to fulfill its objective.

ABSTRACT

Nigeria evidently has a history of national economic planning of policies and programmes which spans both the colonial and post-colonial periods as enunciated in this paper. There is however, no gain saying the fact that no country can attain any form of development without putting in place sound policies and programmes. It is on this premise that the paper established the nexus between government policies/programmes and national development. Thus, Nigeria must thrive to put in place sound policies and programmes if the country must attain the much needed national development towards becoming an economic giant by the year 2020. In the context of the foregoing, the paper recommends among others that; Policies and programmes must be a direct reflection of available human and material resources, cultural realities and political persuasions and also policies and programmes must be rooted in deep democratic norms of accountability, transparency and fiscal discipline because of the choking impact of corruption on policies and programmes in Nigeria over the years.

ABSTRACT

The thrust of this paper is to examine the relationship between corporate social responsibilities and companies performance. Three consecutive years data were collected on profit after tax, companies’ contribution towards education, health and community development from the annual reports of twenty companies quoted in the Nigeria Stock Exchange. The ordinary least square regression result of the data collected on both corporate social responsibilities and firm performance revealed that while there is positive and not significant relationship between profitability and companies’ contribution towards education and health, there is negative and not significant relationship between profitability and communities’ development investment by companies in Nigeria. it is on this note it is recommended that while corporate social responsibilities could be seen as good gesture by companies and therefore encourage, corporate entities should not be coerced to undertake more than what they can comfortably contribute to their host communities as corporate social responsibilities.

Keywords: corporate social responsibility, Corporate Performance, National Health Insurance Scheme, Education Tax.
