Determination of heat flow anomaly in Agbor, delta state
Heat flow values were obtained from four boreholes located at Agbor, Delta State, Nigeria. The values obtained from the four wells, A, B, C and D was respectively 75, 68, 60 and 56mWm-2. However, the average value of 64.75mWm-2 is very close to the estimated value of 65mWm-2 from the semi-empirical law of heat flow versus lithospheric age. The platinum resistance thermometer and the thermistor were used for the measurement of borehole temperature. From the measured temperature distribution, the temperature gradient was computed. The formation heat flow was obtained by multiplying the gradient by the mean thermal conductivity of the rocks. The interpretation of high and low values of heat flow in wells A and D respectively were explained. However anomalous high heat flow values have been observed in well A. The result reveals that a hot plate mobility of heat carrier through some structural boundary and chemical reactions of some organic matters are some specific causes of high heat flow anomaly in the area of the research.

Divalent Nickel (Ni2+) Removal Using Thermally Derived and Regenerated Activated Cocos nucifera Shells
Thermo-chemically cracked cocos nucifera shells were converted into useful adsorbent using chemical activation method. Regeneration of the spent carbon was carried out via thermal regeneration method. The re-derived filter was used in the adsorption of nickel (Ni) from a simulated Ni2+ solution. Qualitative characterization was carried out using the Fourier Transformed Infra Red Spectrophotometer while Atomic Adsorption Spectrophotometer was used to analyze the equilibrium phase Ni2+ concentration. Comparative study of the derived and regenerated activated carbons was carried out using kinetic adsorption studies approach. From the experimental runs, it was evident that derived cocos nucifera shells activated Carbon provided slightly higher removal efficiency values than the vice for Nickel uptake. Investigations with applicability test supported the pseudo second order kinetics as best model in explaining the sorption rate (k2 = 0.744) as against the proposed linear and first order kinetics. Generally, reuse of spent coconut shell carbon and its investigated film diffusion transport mode in removal of Ni2+ is critical a study with a worthwhile adoption in remediation study.

Do interest inventories accurately predict the kind of work in which individuals will be satisfied: definitions, trends and application within a South African context
Vocational interests are an enduring and compelling aspect of individual differences and the most popular means for matching individuals to environments, to improve occupational success and job satisfaction. Interests have received its’ strongest impetus from vocational and educational counselling, gaining considerable attention in areas of vocational choice, such as career development and choice, interest testing and career counselling. It has been to a lesser extent incited by personnel classification and selection. This article attempts to analyse whether interest inventories accurately predict the kind of work in which individuals will be satisfied in.

Effects of ventilation on indoor radon concentrations in offices in Ladoke Akintola University of technology ogbomoso, Nigeria
Radon and its progenies are potential health hazards. The levels of radon concentration in homes and workplaces have been found to depend on meteorological and geological conditions, construction materials, and ventilation. The variation of radon concentration with ventilation conditions in ten offices at the campus of Ladoke Akintola University of Technology, Ogbomoso, Nigeria, has been studied in this work.The measurement of Radon-222 concentrations at each of the locations was done using an active electronic radon gas detector (pro series 3, model HS71512). The statistical variation of the five ventilation conditions with Radon-222 was determined at 0.05 level of significance, using analysis of variance. The Radon-222 concentrations for various ventilation conditions ranged from 20.0 to 51.8Bq m-3. The average concentration of indoor radon in the offices was measured to be 37.0 ± 8.39 Bq m-3. Natural mode of ventilation was discovered to be the most efficient way to lower the radon levels which were observed to depend significantly on the ventilation conditions. Despite the significant effect of ventilation on the indoor radon level, the radon concentration values in all the ventilation conditions investigated however were lower than the recommended intervention level of between 200 – 600 Bq m-3.

Employees’ perception about organizational culture; with and without ethnic diversity
Conducive organizational culture has been proved to be imperative for an efficient organizational performance. Organizations that ensure a favorable work environment for their employees are able to achieve a higher level of professionalism than others. Literature also reveals that a diverse workforce has advantages of more dynamic knowledge, variety of experiences from different backgrounds and multicultural pool of human capital that help create an improved organizational climate through better work involvement, supervisory support, innovation & flexibility, clarity of goals and welfare. Thus if ethnic diversity is integrated with organizational culture of an organization, then it creates a better work environment that leads to an enhanced employees’ productivity. The study was conducted on two higher level educational institutions in two different countries: a university in Pakistan having a homogeneous workforce and a college in the Sultanate of Oman carrying a heterogeneous workforce where diversity is integrated with organizational culture as a diverse work force from many different cultural backgrounds and nationalities is working in Omani educational institutions. After data analysis, it was found that faculty members working in a diversity integrated culture have a better perception about their organization than those serving in a culture without diversity. It was concluded that Employees perceive an organizational culture as more attractive and better in which workforce in ethnically diverse, which also means a favorable organizational climate.
