Measurement and Analysis of Electromagnetic Field Strength in Port Harcourt and its Environs Due to Treasure FM Radio Transmitter

Abstract: This paper Presents the measurement of electromagnetic field strength of Treasure FM transmitter operating at a frequency of 98.5MHz in Port Harcourt and its environs with the aid of an Automated Band Scanner GPS system. The measurement were carried out by taking the radio Station’s transmitter as a reference point at the Centre and selecting 24 measuring points around the transmitter. These points were selected with 1km spacing taken as the interval between two measuring points, summing up to a total of 6km due North, East, West and South of the Radio Transmitter respectively. The result obtained was critically analyzed and interpreted with the aid of an attenuation decay curve. The behavior of the signal was seen to be a function of the Ground Constant of the terrain, reflection of the signal from the earth surface, Diffraction by obstacles and transmitter parameters such as transmitter Power, Antenna Gain and Antenna Height.

Finance Applications Of Game Theory And Behavioral Finance

Abstract: This paper briefly reviews and synthesizes the finance applications of game theory and behavioral finance. It demonstrated how game theoretic techniques have allowed insight into these puzzles with higher order beliefs, informational cascades and heterogeneous prior beliefs. It has also helped in resolving the apparent empirical anomalies in traditional finance theories using the two building blocks of behavioral finance.

Study of Microbial Community of Hydrocarbon Impacted Sites of Bodo Oilfield, Ogoniland Rivers State, Nigeria

Abstract: Hydrocarbon pollution has greatly altered the normal microbial flora of our environments; this has led to the succession of hydrocarbonoclastic microbes in oil impacted sites. This study is a comparative study of the microbial flora of hydrocarbon impacted site of Bodo oilfield and the non-impacted site in Ogoniland. A total of 12 samples were collected, 6 from the oil impacted site, and 6 from the non-impacted site. The sample were coded A –F. The physicochemical parameter of soil was determined, the microbiological examination was conducted to determine the bacterial and fungal communities present at each site. The result shows that higher population of oil-degrading microorganisms were found on the hydrocarbon impacted site, prominent among them were Micrococcus, Acinetobacter, Corynebacterium, Bacillus, Pseudomonas, Flavobacterium, Actinomycetes, fungi isolated from impacted sites includes Candida, Rhizopus mucor and Aspergillus, while the non-impacted site has: streptococcus, staphylococcus, E.coli, and Actinomycetes species. There were also fungal isolate of which only Candida was the only isolate. A microbial growth ranges between 1.1 x 103 to 9.1 x 103 CFU/ml.

Test for Aggregational Gaussianity (AG) in Petroleum Prices Returns

Abstract: The work aims at investigating and establishing if Aggregational Gaussianity, (AG) is in the dynamics of petroleum prices. This AG aspect is the phenomenon in which the empirical distribution of log-returns tends to normality (or as the time scale over which the returns are calculated increases). In order to achieve this, the petroleum price series was tested for arch effects. In addition, tests for Aggregational Gaussianity, (AG) were carried out using qualitative (graphical) approach and inferential approach, (involving statistical inference). The study shows that the presence of arch effects does not guarantee existence of AG. It is also observed that qualitative (graphical) approach may suggest normality and hence, presence of AG, on the other hand, inferential approach (involving statistical tests) gives a better picture of the actual conclusion, of the presence (or otherwise) of AG in the data set, with a 99.97% rejection from normality by the three tests-Kolmogorov-simonorv,Shapiro-Wilks, and Anderson-darling. In the circumstance, there is no evidence to confirm a discernible presence of AG in the dynamics of petroleum prices. The non-existence of AG in the study shows the instability in the dynamics of petroleum prices, since one cannot invoke normality as an invariant property this, among other factors, make the economy unstable as it is oildriven. However, since the highest percentage of the budget for the country is based on the petroleum sales, which as this study reveals is unstable, hence, diversification of the economy is proposed. The softwares used in the work are Eviews 10, Minitab 18, Spss 17, Easy-fit 5.6 professional, and R 3.2.2.

Variations in growth performance traits and economic analysis of two Nigerian indigenous chicken strains and their crossbred

Abstract: This study was undertaken to compare growth performance and economics of production of two Nigerian indigenous chicken strains andtheircrossbred.The parent lines of theNigerian indigenous chicken population used consisted of two strains, the normal feather (NF)and the naked neck(NN),obtained from pure bred strains of Nigerian indigenous chickens maintained at the Directorate of University farm, Federal University of Agriculture, Abeokuta, Nigeria. Three genetic groups comprising a combination of NF male X NN female (GG1), NN male X NN female (GG2) and NN male X NF female (GG3) were used for the study. The results revealed that though chicks from GG2 were heavier (P 0.05) among the three groups. Birds from GG3 were however, able to utilize feed consumed by 11.21 and 12.93% more efficiently than GG1 and GG2 respectively. Feed cost per kg weight gain was least for GG3 ( 520) with gross margin of 132.35 and 133.43 above GG1 and GG2 respectively. GG3 had the best profitability index and return on investment. Crossbreeding naked neck and normal feather showed superiority in growth and economic returns and is therefore recommended in breeding/production programmes targeted at expanding Nigerian indigenous chicken production.
