Aim: This study aimed at compiling all hepatitis B results for prospective employees screened at the Cape Coast Metropolitan Hospital. This information is relevant in identifying those who are already infected, as well as susceptible individuals, to promote the establishment of prevention and control measures within work environments. Method: This study extracted data from laboratory records into Microsoft Excel and used for the analysis. Results: In this report, 13.3% (4/30) of prospective employees were found to be sero-positive for hepatitis B surface antigen (HBsAg). The remaining were sero-negative (susceptible), and required vaccination. All of the four (4) found to be sero-positive were chronically infected [both hepatitis B envelope antibody (HBeAb) and core antibody (HBcAb) - positive], that is, capable of transmitting to susceptible individuals if the proper infection prevention practices are not well implemented in their homes and work places. Only males were found to be positive, while all females were negative. Conclusion: Continuous education, screening, management of infected individuals and vaccination of the susceptible, will go a long way to curbing the spread of hepatitis B infection. Contribution/ Originality
This study contributes to existing information, and draws attention to occupational support in the management of hepatitis B infection. Medical Sciences » Journal of Diseases » Month: 03-2020 Issue: 1

Journal: International Journal of Business, Economics and Management
This study seeks to construct a financial safety index (FSI) for Nigeria. FSI is important for early detection of financial stress and ensures that the financial system is better positioned to reduce the likelihood of financial crisis and negative outcomes on real economic activities. It has capacity to guide policies that are likely to ensure the safety of financial system as well as those that are likely to distort the system. It also has ability of providing support for policy on external economic factors that can affect a country’s financial system. Hence, the developed index incorporates factors that have made significant impacts on Nigeria’s financial system in recent years. It is estimated using principal component analysis (PCA) and some major incidents of systemic pressure were identified from the constructed FSI. The constructed FSI was able to largely capture key macroeconomic trends and developments that shaped the financial industry within the study period. This confirms the relevance of the indicators selected for building the index and implies that the selected indicators played critical roles in the determination of Nigeria’s financial safety. Therefore, the index would assist both the fiscal and monetary policymakers in taking preventive measures against financial instability. Contribution/ Originality
This study contributes to the existing literature by constructing a financial safety index (FSI) for Nigeria, based on major factors that have made significant impacts on the financial system in recent years. The study, therefore, tests previous theories with recent data and suitable methodology. Economics » International Journal of Business, Economics and Management » Month: 01-2020 Issue: 1

Journal: The International Journal of Biotechnology
Dearth of information on response of hexapod orders to light sources and colours informed this study. The study was conducted in Federal University Wukari, Nigeria in the month of May, 2019 to evaluate the attractiveness of hexapod orders to Light-emitting Diode (LED) and Incandescent bulb light colours. Daily sampling using fabricated light traps with 5 different colours (white, yellow, red, green and blued) for each bulb type in 6 replicates was done. A trap with no lighting source was the control. Hexapods collected were sorted into their respective orders. Of the overall 13 insect orders collected, LED bulbs attracted 11 while incandescent, 10. Even though, certain hexapod orders exhibited higher affinity to specific colours, statistical analysis revealed that of the 11 orders from LED, differences in the mean number of insects attracted among the bulb colours was significant (p<0.05) only in Coleoptera and Lepidoptera while for incandescent bulb colours, the mean number of insects attracted was significant for Coleoptera, Lepidoptera, Hemiptera, Hymenoptera, Orthoptera, Mantodea, Odonata and Homoptera. Insect orders generally had higher affinity to white and blue colours. LED bulb colours significantly attracted higher number of insects than their corresponding incandescent colours, except for white on which incandescent was more attractive (p>0.05). Overall, attractiveness to hexapod orders increases with rinsing light intensity and LED bulbs were found to be more attractive to hexapods than do incandescent bulbs. Therefore, LED bulbs of higher light intensity with colours around the blue/white spectrum show potential for use in manipulating hexapods for man’s benefit. Contribution/ Originality
This study discovers that hexapod orders are largely highly responsive positively to blue and white electric light of higher intensity. It also shows that, the LED bulbs were generally more attractive to the hexapod orders than the incandescent. This knowledge can be harnessed in manipulating the hexapods for man’s benefit.

Journal: International Journal of Climate Research
This study was carried out to evaluate the level of environmental awareness of stakeholders in the urban and rural settlements in Delta State, southern Nigeria so as to infer the depth of environmental education that would be embarked on. Five major stakeholders in the state that constituted the major strata of sampling were selected. A total of 14 communities; 7 in the urban/semi urban local governments and 7 in the rural local governments were studied using the stratified sampling technique. Descriptive statistic was adopted for the study and questionnaires were administered to stakeholders. The study revealed that contrary to findings from a number of studies in other part of the globe, students were more knowledgeable on environmental issues followed by public/civil servants and traders/businessmen among stakeholders from the urban settlements. Stakeholders younger in age were not more knowledgeable than older stakeholders in the rural settlements about environmental problems. Male stakeholders had higher percentage level of awareness than their female counterparts. A higher percentage of stakeholders from the rural settlements are still not aware on the environmental terms sought for in this study than stakeholders from urban settlements. This study recommends that given the current level of environmental degradation experienced on a daily base in Nigeria and the limited awareness level of stakeholders on environmental issues, government at various levels should through wider publicity in the ministries of environment and education intensify the campaign on environmental education. Contribution/ Originality
This study is one of the very few studies which have investigated the environmental awareness level among stakeholders in the rural-urban communities of Nigeria. The analysis and findings will enrich the depth of available literature on environmental awareness of stakeholders in developing nations.

Journal: International Journal of Education and Practice
This study aimed at designing a framework to help students develop a conceptual understanding of redox reactions, which draws on constructivist learning theory. This framework was in the form of participatory teaching and learning approach comprising Insight, Interaction, Task, and Forum. The framework was designed and developed based on the literature and used in a teaching trial. At the prototype phase of the design-based approach, a mixed methods design was employed in data collection. Fifteen students from a second-year senior high school class responded to the achievement test and interacted with the researchers. A stratified sampling procedure was used to select the students. In lessons on redox reactions, the framework helped the teacher to identify students’ alternative conceptions and confronted them through cognitive engagements leading to conceptual understanding in redox reactions. Percentages, related samples t-test, and themes were used to analyse data. The results showed that there was an improvement in students’ conceptual understanding of redox reactions. It is, therefore, recommended that chemistry educators and researchers should use the framework in large scale research to assure the scientific community the efficacy of it in developing conceptual change in students. Contribution/ Originality
The study contributes to the existing literature by the design and development of an alternative framework for participatory instruction, which is all encompassing in approach. Unlike other instructions, the framework; Insight, Interaction, Task, and Forum, takes advantage of alternative conceptions and ends with students’ ability to evaluate colleague’s presentations.

Chemical Changes Associated with Repetitive Re-Use of Vegetable Oil during Deep Frying of Bean Cake, Plantain and Yam
Oil re-use is a common practice in households. Oxidative and hydrolytic reactions have been reported to cause significant changes in oil quality. This study was carried out to determine the chemical changes specific to beans cake (Vigna unguiculata), Plantain (Musa paradisiaca) and yellow yam (Discorea cayenensis) frying with repetitive re-use of oil. Refined vegetable and palm oil were used for five consecutive frying operations for bean cake, plantain and yam. Free fatty acids, iodine value, peroxide value and saponification value of the first, third and fifth frying operations were determined using standard methods. For refined vegetable oil, the FFA range for repeated frying operations obtained for bean cake, plantain and yam were 0.31-0.53, 0.37-0.52 and 0.40 to 0.53 % oleic respectively. While palm oil re-use had a range of 11.87 to 14.97 in the value of their FFA. Peroxide value (3.24- 4.92 meq/kg), Iodine value (91.09-107.00 mg/100g) and Saponification value (125.00-152.66 mgKOH/g) were obtained for re-use refined vegetable oil while Peroxide value (27.95-77.02 meq/kg), Iodine value (131.68-210.89 g/100g) and Saponification value (179.45-197.50 mgKOH/g) were obtained for re-use palm oil. Generally, frying operation led to increase in the FFA of refined vegetable oil. Frying operation for peroxide value significantly varied for all frying operation for plantain. Significant difference existed in iodine value at p<0.05 among frying operations for bean cake and yam. Changes in chemical properties of oil were affected by frying duration and food material fried. Contribution/ Originality
The present study reported variations in the chemical properties of vegetable oil as affected by the type of food material (bean cake, plantain and yam) during repeated frying operation. Extent of changes caused by hydrolytic and oxidative reactions is dependent on the food material used for deep frying operation. This work also was able to ascertain that acceptable oil re-use depended on the frying duration and food material.

Utilization of multispectral satellite images is an excellent approach in the reconnaissance stage of gold prospecting due to its high effectiveness and low cost. This research used Landsat 8 Remote Sensing data and Geographical Information System to identify, delineate and map hydrothermal alteration zone relating to gold pattern mineralization in Prestea Huni Valley District in the Western Region of Ghana. Principle Component Analysis (PCA), three band combinations, spectral rationing and Crosta techniques are used in this study. For three band combinations, bands 5, 4, 3 and 5, 6, 7 are used to map location of hydrothermal alterations. Band ratios (7/5and6/7), (6/5) and (4/2) are used to identify presence of clay, ferrous and iron oxide minerals respectively. Sabin's ratio 4/2, 6/7 and 6/5, Kaufmann ratio 7/5, 5/4 and 6/7, and 4/2, 6/7 and 5 are used to identify vegetation, outcrop and hydrothermal alterations respectively. Crosta and PCA techniques were used to suppress the interference of vegetation in delineating the alteration zones. Results revealed that the three band combinations and spectral ratioing clearly depicts hydrothermal deposit of ferrous minerals, clay and iron oxide minerals. PCA identifies presence of iron-oxide and hydroxyl minerals as bright pixels. The first three high order principal components (PC1, PC2 and PC3) of input spectral bands gave more than 98% of the spectral information. Thus, the results from satellite images an effective and efficient way of mapping hydrothermal alteration zones at regional scale. Contribution/ Originality
This is one of the very few studies which have investigated to identify hydrothermally alteration relating to gold mineralization.
