Effect of operating variables on exergetic efficiency of an active gas turbine power plant

Abstract: The effect of operating thermodynamic variables on the exergetic efficiency of an active gas turbine power plant was investigated. The study is primarily aimed at analysing the performance of the turbine plant and examine how the changes in the operating thermodynamic variables affect the performance of the gas turbine components and the entire turbine plant. The operating variables considered are: ambient temperature (AT), turbine isentropic efficiency (TIE), compressor isentropic efficiency (CIE), compressor pressure ratio (CPR) and turbine inlet temperature (TIT). The results obtained show that a degree increase in AT, lead to 0.45% decrease in the overall exergetic efficiency of the plant, 0.27MW increase in total exergy destruction rate and 0.1%, 0.32% and 0.23% increase in exergy destruction rate of the compressor, combustion chamber and turbine respectively. Similarly, the overall exergetic efficiency of the turbine increased by 0.06% for 5% increase in CPR and decreased by 0.04% for 7% increase in CPR. TIT, TIE and CIE have profound effect on the exergetic efficiency of the plant. However, for moderate changes in CPR, CIT and TIE no severe changes were noticed in the gas turbine performance.

Conflict Management in the Nigerian University System

Abstract: Conflict is an attendant feature of human interaction and cannot be eliminated; however, its proper management and transformation are essential for peace and progress in human society. It has been observed that Nigerian universities has for decades been faced with so many crisis ranging from conflict between academic staff and university administrators, students versus academic staff, students versus university authorities , non-academic staff versus university administrators. The conflicts have given rise to distrust and hostility among professionals and academics, thus, contributing in hampering smooth, effective and efficient administration in the universities. It also appeared that despite this situation, stakeholders in education seemed to develop non-challant attitude towards these conflicts. If this role conflict is not checked it can be descriptive and negative as people involved will often see one another as enemies. This is unwholesome for the University community and Nigeria educational system as a whole. This paper examined conflict management in higher institutions of learning with specific reference to Nigerian Universities. Some causes of conflict were identified as well as ways these conflicts could be managed. Well-fashioned recommendations on how conflict could be more effectively managed for the achievement of the system's mission, goals and objectives and in particular the pursuit of industrial harmony in the system were also made.

Contending Issues in the Management of Intergovernmental Relations in the Nigerian Federal Administration System

Abstract: Intergovernmental Relations (IGR) is the interaction that takes place among different levels of government within a country State governments are independent within constitutional limitations of the centre while local governments are subordinated to the states Usually, the concept is mostly associated with states having a multi-ethnically segmented administrative system like Nigeria where relationship between the Federal and the major component units are formally spelt out in the constitution A full analysis of IGR must cover Federal-State-Local, Federal-State, Federal-Local, Inter-State, State-Local, and Inter-Local relations enshrined in the constitutional framework The main issues given prominence in the study of IGR, are the allocation of jurisdictional/constitutional powers, administrative/political mechanisms, and intergovernmental fiscal relations This paper attempts to examine each of these issues in turn highlighting the increasing dependence of the states and Local Governments on the Federal government and the ubiquity of Federal Government in areas considered an exclusive pressure of the state and local government It also draws the attention to worthwhile lessons that Nigeria could learn from the experiences of its operation in a federal administration system DOI: 105901/mjss2014v5n3p226

Onchocerciasis in the upper imo river basin, Nigeria: prevalence and comparative study of waist and shoulder snips from mesoendemic communities.

Abstract: Background: Onchocerciasis is endemic in the Imo River Basin, Nigeria. This study was aimed at assess­ing the prevalence and intensity of microfilaria of Onchocerca volvulus in the area. Methods: A cross-sectional study was carried out in the Okigwe Local Government Area, Imo State, Nige­ria. Two skin snips (one from the waist and another from the shoulder) were taken from 1024 individu­als examined. The survey coverage was high (91.8% of the study population). An individual was considered mf positive if either of the waist or shoulder snips or both were mf positive. The SPSS for Win­dows package was used for entering and analysis of data. Results: Thirty-seven percentage of those examined was positive for Onchocerca volvulus microfilariae (39.2% of males and 34.9% of females). The mf prevalence increased steadily with increasing age to reach 70.4% in the oldest age group. The overall mf Geometric Mean Intensity among mf positive individuals was 16 mf/skin snip and was significantly higher among males (18 mf/skin snip) than females (14 mf/skin snip) (p < 0.01). A scatter plot of microfilariae numbers in snips from the waist against numbers in snips from the shoulder of the same individuals, showed close correlation (Pearson's correlation coefficient = +0.90; p < 0.01), and those with mf intensities below 10 mf/snip had a more scattering tendency away from the regression line than those with higher mf intensities. Conclusion: Onchocerciasis is a public health concern in the area. Perhaps, 10 mf/snip is critical intensity threshold for reliable sampling using corneo-scleral punch.
