Estimation of Background Induced Temperature in and Around Bakery Ovens for Some Selected Locations in Calabar

Abstract: Estimation of background induced temperature from six selected Bakery Ovens in Calabar was investigated. An in-situ measurement approach was adopted in order to quasi-accurately estimate temperature of Oven; wind speed in bakery and ambient temperature around the bakery. The relationships between the measured parameters were obtained from plots of wind speed against Temperature and Temperature of oven against distance from Oven. Statistical correlations of wind speed values and temperature were estimated, which yielded a good positive correlation coefficient for wind speed and temperature in all cases and for all the six locations under study, with the relevant plots; these clearly show that all of the two parameters; wind speed and temperature are necessary to be used in analysing and assessing the wellbeing of workers in the perceived heat stressed environment. On the other hand, the coefficient of determination value shown on each of the correlation plots depicts that the models relating the Temperature and wind speed in each case respectively are good performing models. It was found out that the temperature exposure of workers in all the bakeries under study exceeded the WHO (20oC -29oC) exposure limit for comfort. All the bakeries visited during this study used firewood industrial oven.

Impact of social media use on utilization of library resources: a study of post-graduate university students in cross river state of nigeria

Abstract: Research Goals: This research investigates social media platforms' impact on “utilization of library resources by postgraduate students in Universities of Cross River State, Nigeria”. This study recognizes how social media has influenced our life daily, the people using social media are increasing day by day. Currently, social media tools have become important communication and learning tools to attract everyone with its unique features of information update. The social media users can share their ideas, images, documents, and videos with others through social media platforms like WhatsApp, Blogs, and YouTube. One major challenge of libraries has been the accessibility and “utilization of library resources, low utilization of library resources mostly by postgraduate students has necessitated this research work to find out the influence of WhatsApp, Blogs, and YouTube on the utilization of library resources among postgraduate students if deployed in libraries. To achieve this, one hypothesis was formulated. The study made use of postgraduate students of Universities in Cross River State, Nigeria.Methods: The research design for this work was survey research. The population was 565 post graduate students. Accidental and purposive sampling techniques were used to select the sample. The instrument for data collection was a structured and validated questionnaire titled social media platforms impact on the utilization of library resources (SMPIULRQ). Cronbach Alpha reliability method was used to estimate its reliability. The data were analyzed using Multiple Regression statistics. The hypothesis was tested at .05 level of significance.Results /Findings: The findings reveal that there is a significant positive influence of WhatsApp”, Blogs, and YouTube on the utilization of library resources.Conclusion/ Implications: Librarians should create an adequate technology environment in the library that will promote and encourage the use of social media tools or platforms to increase student's utilization of library resources. This will help them develop ICT skills in the ever-changing world of technology. It was also recommended that postgraduate students should make an individual effort to train themselves on the use of social media platforms for academic as this will help them learn more effectively.

A Critique on the Foundational Response Surface Methodology for Exploring Optimal Regions

Abstract: The interest of most process engineers in industries is usually to optimize the yield of their processes. Not until 1951, imprecise methodologies were used in industries for this purpose. However, in 1951, G. E. P. Box and K. B. Wilson invented the technique of Response Surface Methodology (RSM) as one used for the optimization of the yield of processes. Being an initial idea, this paper has considered RSM as a foundational idea. In particular, it criticizes this foundational idea from the angle of its intuitive approach to searching for near-optimal settings of industrial processes, should such processes fail to run at optimal settings. RSM uses the tools of canonical transformation and analysis (a trial-and-error routine) for this search. Regardless, the foundational response surface methodology is acknowledged to be primarily efficient for determining the optimum response.
