Computer-Based Laboratory Simulation (CBLS) as an effective instructional approach for electro-chemistry lessons and Rivers State students’ academic performance in chemistry was investigated in this study. Quasi experimental research design was adopted for the study. The purposive sampling technique was used to select Emohua local government area out of the nine (9) local government areas in Rivers State central educational zone in Rivers State. Simple random sampling by balloting was used to select four (4) senior secondary schools out of the eighteen (18) schools inn Emohua local government area that participated in the study. The non-ramdomized sampling was used to obtain a sample size of one hundred (100) SS2 chemistry students comprising 55 males and 45 females that participated in the study. The chemistry performance test instruction was used to collect data for the study. The data collected were analysed by using mean and standard deviation to answer all the research questions while analysis of covariance was used to test the hypothese at .05 level of significance. The study found that, there is significant difference between the mean performance of students exposed to CBLS in chemistry and those taught using lecture method, P.05. The study recommends that chemistry teachers should often CBLS to enhance higher performance of students in chemistry.

This research investigates the geothermal properties of hydrocarbon reservoirs in Tebidaba Field, OML 63 in the Niger Delta basin, Nigeria, using continuous temperature, gamma ray, neutron, density and resistivity log data. Techlog and Excel softwares were employed for data loading, analysis, and visualization of reservoir tops, and bases. The results showed that the reservoir thickness ranges between 18.24m and 45.06m with an average of net thickness of 37.74m. The temperature of the reservoirs ranges between 83.11 and 83.59oC with average reservoir temperature of 83.14oC.  The geothermal gradient ranges between 12.62oC/km to 17.57oC/km with an average of 16.70oC/km.  The thermal conductivity varies from 2.06Wm-1k-1 to 2.58Wm-1k-1 with an average of 2.43Wm-1k-1. Heatflow ranges from 32.56mWm-2 to 45.38mWm-2 with an average of 40.54mWm-2. The porosity of the reservoirs ranges between 28.54% and 38.90% with an average of 33.55%. Shale volume ranges from 0.50 to 0.63 with an average of 0.56 in the reservoir. The sand volume ranges between 0.37 and 0.50 with an average of 0.44. The results suggest that the hydrocarbon bearing sand reservoir has a favourable geothermal condition and highlights the influence of depth, porosity and lithology on the thermal characteristics of the reservoirs. The crossplots of temperature against depth and lithology validates the fact that temperature increases with depth as sand volume decreases, while shale volume increases with increasing depth. This study provides a new insight of the geothermal properties of hydrocarbon reservoirs in Tebidaba Field ( OML 63), which is crucial for evaluating reservoir productivity and exploitability.

Sedentary behaviour characterised by prolonged sitting or low energy activities such as screen time has become increasingly common among young adults due to academic, occupational and social demands. This lifestyle is associated with negative health outcomes such as reduced physical fitness, increased risks of obesity and poor mental wellbeing. The study investigated the determinants of sedentary behaviour among young adults in Port Harcourt Local Government Area, Rivers State. A descriptive survey design was adopted for the study and the population comprised of all young adults in Port Harcourt Local Government Area, Rivers State who were resident in the area as at the time of the study. Cochrane formula was used to obtain of sample of 384 and a multistage sampling procedure was used to distribute the sample. The instrument for data collection was a self-structured questionnaire with 0.774 coefficient of reliability. Descriptive analysis was done using frequency counts, percentages, mean and standard deviation, while the hypotheses were tested using Analysis of Variance (ANOVA) at 0.05 alpha level of significance. The findings showed that 16.9% exhibited very high sedentary behaviour. 50.0% of respondents between 20years and below exhibited high level of sedentary behaviour while 76.0% of those between ages 31years and above exhibited low level of sedentary behaviours. More than half of the respondents (both males and females) exhibited high level sedentary behaviour. 63.3% of those who always succumb to negative peer pressure exhibited high level of sedentary behaviour while more than half of those who were poor as well as those who were in the upper exhibited high level of sedentary behaviour. More than half (63%) of the respondents with good health status exhibited low sedentary behaviour while more than half of those with very poor health status exhibited high sedentary behaviour. Furthermore, it was revealed that age (F= 13.065; p= 0.000), peer pressure (F= 18.140; p= 0.000), socio-economic status (F= 11.352; p= 0.000) and health status (F= 10.356; p= 0.000) were significant determinants of sedentary behaviour among young adults in Port Harcourt Local Government Area, Rivers State. Parents and caregivers should organize family outings that involve physical activities such as hiking, biking, or team sports to encourage their wards participate in a more active lifestyle; in addition, Public Health Workers should run awareness campaigns through social media, television, and community programs to educate youth and their families about the importance of reducing sedentary behaviour and increasing physical activity.

With keen research interest, this paper focused on the provisions of urban infrastructural facilities by major stakeholders and  the numerous benefits derived from it in the long run.  The aim is to see how satisfactory residents are and beautiful the built environment appears or looks when infrastructural facilities are developed and managed properly by experts. The researchers adopted a method that utilizes both primary and secondary sources of data collection.Questionnaires were administered to residents in the field within the study areas, and the retrieved questionnaire formed the basis for analysis and interpretations. The researchers preferably made use of the descriptive statistics because it gives room for easy understanding and explanations. Furthermore, a very interesting statistical tool called chi-square was also significant in the testing of hypothesis carefully formulated in the body of the work. The study revealed that, infrastructural facilities development is capital intensive but its importance cannot be over emphasized. Recommending that, government at all the levels should declare a state of emergency on the development of infrastructure owing to its economic and environmental values. The study concludes that government should encourage private individuals in the building and management of infrastructural facilities

Probiotics are live microorganisms that confer health benefits when consumed in adequate amounts. Probiotics have been widely known for its beneficial effects on human health. They consist of different types of foods for many decades. Fermentation, is an old method that has been used to improve nutritional value and food preservation. Fermented dairy products and vegetables have been suitable means for consumption  of probiotics. In Africa, many of the seasoning agents are products of alkaline fermentation of  plant-seed, legume based products and in some cases, animal proteins and seafood. Consumption of probiotics have shown antimicrobial, anti-inflammatory, and cholesterol-lowering effects due to its symbiotic blend of bacteria and yeast. Probiotics contain antioxidants to protect the body from oxidative stress and chronic diseases. Probiotics support microbial diversity in the gut, enhances lactose digestion, reduce diarrhoea, aids digestion and improves lactose tolerance. Various types of bacteria are generally contained in probiotics, they are Lactobacillus, Streptococcus, Lactococcus, Enterococcus and Bifidobacterium. Although it has seemed that dairy products were the primary source of probiotic bacteria until now, the popularity of fruit and vegetable juices is increasing more rapidly. Previous studies have revealed some indigenous Nigerian local foods, beverages, staples and spices like pap, garri, palm wine, iru, ugba, etc, that we consume are actually excellent sources of probiotics. Probotics have been proposed as preventive and therapuetic measures, in order to restore the healthy composition and function of the gut microbiome. By incorporating probiotics into our diet and lifestyle, we can take a proactive approach to maintaining our health and preventing diseases.
