One hundred and forty five (145) senior secondary two (SS II) students from four co-educational secondary schools were used as sample for the study. A 35-item Likert scale instrument called Students’ Motivation toward Learning Physics Questionnaire (SMoTLPQ), whose reliability coefficient was computed as 0.72 using Cronbach’s coefficient alpha method on the Statistical Package for Social Sciences (SPSS) Software Version 25, was used to elicit information. Three research questions were raised and answered using mean while four hypotheses were formulated and tested at α = 0.05 using Analysis of Covariance (ANCOVA). Findings revealed, amongst others, that students taught using J4CLSachieve significantly higher than students instructed under conventional lecture method (CLM), irrespective of gender and the type of school they attend. Based on the findings, recommendations were made which include encouraging Physics teachers to employ J4CLSin teaching secondary school students, since the method has been found to improve students’ motivation toward learning Physics and it is gender-friendly and independent of school type in terms of improving their motivation.","PeriodicalId":104417,"journal":{"name":"International Journal of Research Findings in Engineering, Science and Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129714669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Battery storage is needed because of the intermittent nature of photovoltaic solar energy generation and also because of the need to store up excess energy generated in periods of high demand or for sales to the National Grid System. The study consists of three parts; namely: (a) to undertake a comprehensive review of current battery storage technologies. (b) To investigate the performance of the main battery storage technologies that is commercially available (efficiency, energy density, power density, self-discharge per day and power rating); (c). Undertake comparison of battery energy storage technologies. From the findings, it shows that the Lithium Ion Battery technology is the most reliable and most widely used technology for residential applications. It has the best performance characteristics (efficiency, energy density, power density, moderate self-discharge and power rating) however, lithium ion batteries are still relatively expensive among others. Due to these features the Lithium Ion Battery technology stands a total chance of dominating the Battery technology market for residential and automotive applications. Also shows from the findings, the performing reliability of the Lithium ion battery by using the battery application requirements and the dangers in operating at a not required specification. More recommendations were made in areas of challenges faced by the battery storage technologies in order to make improvement.","PeriodicalId":104417,"journal":{"name":"International Journal of Research Findings in Engineering, Science and Technology","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128178123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is however a lack of studies on water quality using multivariate statistical techniques to predict the sources of pollutant along Otamiri-Ochie River. Multivariate statistical approaches, including principal component analysis (PCA) and cluster analysis (CA) were employed to evaluate the water quality of the River. In this study, eight physico-chemical parameters were analysed in each water sample collected from four sampling sites surrounded by dumpsites along the River. Exploratory analysis of the dataset involved use of PCA, CA and water quality index (WQI) in attempt to identify the sources of variation measured in the samples. PCA was used to reduce the dataset to three components with predominantly dissolved oxygen (DO), total dissolved solids (TDS) and total suspended solids (TSS) contributing to over 55% of the total variance. CA classified the sites into two distinct groups identified as the upstream and downstream of the River. Chokocho (CHR) axis of the River was identified as being closer to the pollutant source and hence it is the most heavily polluted portion of the River. WQI value suggests that the water is unsuitable for drinking and may likely not be fit for domestic uses. The results prove multivariate statistics to be a powerful tool in identifying pollutant sources, which can be applied to both urban and rural water bodies.","PeriodicalId":104417,"journal":{"name":"International Journal of Research Findings in Engineering, Science and Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133249286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, to show the application of Z-test statistical tool in research. Adamawa state is the area of study and 392 building and construction workers that were convicted for offences of various categories in the area of the study is the population of the study, what is the gender difference in crime involvement by workers in the building and construction industry in Adamawa state? Is the research question. The null hypothesis tested was “there is no significant difference in gender in crime involvement by workers in the building and construction industry in Adamawa State.” The study was based on secondary data extracted from Adamawa State Statistical Year Book 2012 for period of 4 years (20012-2016). Ten crime types that included theft, cheat, trespass, enticement, deformation of character, mischief, force and assault, conspiracy, intimidation, possession of weapons, were considered for the study. The data obtained was analysed and the hypothesis tested using Z-test at 0.05level of significance. The result of the analysis showed that female workers commit less crime than male workers in the building and construction industry in Adamawa state. The study recommended that, there should be Prompt and consistent punishment for male workers offenders so as to help reduce the incidence of male workers crime commitment high rate. Positive motivation of the workers in the building and construction industry in the state was recommended. The significance of the study if published include: 1. Adamawa state building and construction industry managers will benefit from the findings of the study because it had remained them on crime involvement rate by workers in the industry and that may motivate them to include remedies or control measures in the management of their workers. 2. Authors and researchers too, because it will remain them on how and when to apply the Z-test of hypothesis when writing: research reports, journals for publication, and other similar issues. 3. Similar benefit goes to the Building and construction industry stakeholders, in that it can be a source of information to them at home and workplaces on the behaviours of their workers in relation to crime commitment in the industry. 4. Not only the above stated, Building and construction industries workers themselves will learn some lesson when they witness high gravity of punishments being awarded for such offences in the industry as listed above.","PeriodicalId":104417,"journal":{"name":"International Journal of Research Findings in Engineering, Science and Technology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128489973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative analysis of hotel operating statistics for the purpose of classification is achieved through inter-hotel comparison scheme. Inter- hotel comparison is a system where hotels of comparable standards agree that their performance statistics be collected, analyzed and compared by a center so that each hotel is able to assess its performance in relation to other hotels in the scheme. Hotels in Yola lack this medium. The purpose of this study was to determine the perception and willingness of hotels to participate in a comparative scheme with a view to improving on their service quality delivery and financial activities. Three ratios each of profitability and cost factors were investigated in twelve (12) hotels. Raw figures supplied by the hotels were processed into ratios through the process of common size analysis. It was found out that the hotels have understanding about the importance of inter-hotel comparison and the resources to participate in such scheme. A trial analysis of available ratios showed that some of the hotels were actually doing better than others.

The extract proportions 2, 4, 6, 8 and 10 (mg/ml) respectively were used to formulate the soaps. The results of the soap characterization were: pH (9.3); foamability (3.5cm), color (light yellow).The antibacterial investigation used Ciprofloxacin and ketoconazole as positive controls whereas Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and Candida albicans were clinical isolates of microbes used. Sensitivity test was conducted and an in vitro evaluation of the anti-microbial activity was conducted using ditch-plate techniques. Strains of reference microbes namely Candida albicans, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli were tested at four different soaps’ concentrations (0.0, 2.0, 5.0 and 8.0 mg/ml). ANOVA mean results of zones of inhibition also revealed variability of antimicrobial activity among the natural formulated soaps with strong positive correlation (r= 0.9912 ; P > 0.01) between zones of inhibition and soaps’ concentrations was evidenced. Blend 8:2 of the formulation exhibited the largest zone of inhibition (40 mm) on S. aureus, followed by Candida albicans with (35 mm) zone of inhibition whereas the least zone of inhibition (1.8 mm) was observed in 2mg/ml extract formulation. The high pH shows it conforms to NAFDEC set range of 9 to 11 pH.
