Thus, the need to look into ways of accelerating and transforming carrot utilization into more commercialized usage in order to add value to the developmental strides of any nation where carrot is cultivated like Nigeria. This study concluded that the optimization of the carrot oil extracted from crushed carrot and coconut oil (biomass volume) via soxhlet equipment using Box-Behnken Design (BBD) of Response Surface Methodology (RSM) approach, generated an ideal optimal output of 18.58 wt% at SW of 60 g, BV of 200 ml and ET of 14mins. Although, three input elements which are sample weight (SW), biomass volume (BV), and extraction time (ET) were modelled to generate 17 setups by BBD, but standard order (Std) 8 from the 17 setups generated an ideal output of 18.58 wt%. Thus, the process optimization of the extraction process via BBD of RSM showed that both the coefficient of determination (R2) which is 0.9886, and the difference between adjusted R2 and predicted R2 which is less than 0.2 fall within an ideal range. Also, the elements considered for modeling are mutually significant with the quadratic model equation and the interactive effects of the independent parameters on the carrot oil output showed that an increase in the sample weight and time led to a corresponding increase in the carrot oil output, and this is corroborated by the perturbation plot. Additionally, the physiochemical valuables of the carrot oil generated showed that the free fatty acid and the acid value were very low signifying that the carrot oil is edible and can be used in the manufacturing process using the saponification method in making soap and moisturizing cream for the benefit of mankind.","PeriodicalId":508164,"journal":{"name":"Journal of Engineering Research and Reports","volume":"12 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140081897","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}

To tackle this issue and maximize well production, obtained pressure build-up time data at a steady production rate from a vertical producing oil WELL 20A, was analysed to establish the wellbore and reservoir characteristics. A numerical well test simulator (Matlab) is used to simulate damage in the area close to the wellbore, a Microsoft Excel sheet and an analytical approach to calculate the impact of wellbore and reservoir factors such as skin, wellbore storage, and average reservoir permeability. In order to determine whether the numerical well test simulator was successful at performing pressure transient analysis on observed data, the findings from the analytical solutions using Microsoft Excel Sheet and numerical well test simulator Matlab were compared. Comparable outcomes for the permeability and skin values were obtained from the build-up test data analysis generated; hence, the negative skin values for wells 20A acquired after the analysis suggest that the formation is not damaged. This indicate that well 20A is not a candidate for workover operations.","PeriodicalId":508164,"journal":{"name":"Journal of Engineering Research and Reports","volume":"35 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140432019","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}

For the safety of plane gate, this paper adopts Ansys software to establish a finite element model of plane gate, and calculates the most dangerous point stress of plane gate by considering its most unfavourable loading condition. At the same time, the service life of the allowable stress reduction was considered. The analysis results show that the planar gate meets the strength safety. The main beam is simplified into slender beam and thin-walled deep beam, and the calculation formula of slender beam in the mechanics of materials and thin-walled deep beam in the literature is used to calculate the positive bending stress in the mid-span cross-section of the main beam of the gate, and a comparative analysis is carried out with the results of Ansys, which shows that the positive bending stress in the mid-span cross-section of the main beam obtained by simplifying the main beam into a thin-walled deep beam is more close to the results of Ansys calculation.

This work evaluated ergonomic compliance and work-related musculoskeletal disorders among fully remote workers in Lagos. Following approval, 371 remote workers were recruited to participate in a cross-sectional study. They responded to a Questionnaire, the main study tool, which biodata, work information, knowledge of ergonomics, workstation compliance, level of support offered by employer to aid ergonomic compliance, behavioral factors, musculoskeletal disorder symptoms and medical Information regarding past and present diagnosis/ treatment. To support data on workspace compliance, physical and virtual observations were carried out on 361 workspaces. Collated data were analyzed using descriptive tools. The data analysis showed that a large percentage of remote workers, about 66.31% had high knowledge on ergonomics. However, a relatively lower percentage, about 23.36% had highly compliant workspaces. Only 8% were highly compliant based on behavioral patterns as a larger 48% fell into the low category. The study showed that only 15.36% of employers gave a very high level of support to encourage ergonomic compliance. The Most prevalent musculoskeletal disorder amongst the population studies is the lower back pain, which has been suffered by 90.5% of respondents at varying durations and levels. This was closely followed by the upper back pain at 85.7% then eye pain at 47.1. The study shows a positive correlation between Employer support and: ergonomic compliance based on workspaces, ergonomic compliance based on behavioral patterns as well as knowledge on ergonomics at 0.26828222, 0.151881985 and 0.188086546 respectively. There is an urgent need to educate employees on ergonomic safety, create effective occupational health plans tailored specifically for the remote work model, develop feasible measures for compliance checks, and work with authorities to enact laws to protect the health and safety of remote workers in the long run.","PeriodicalId":508164,"journal":{"name":"Journal of Engineering Research and Reports","volume":"109 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140439775","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}

The system can produce an electric signal that can emit mechanical ultrasound signals to be harnessed using a series-connected eight piezo-electric discs. To power up the system, it uses four Li-ion rechargeable batteries charged by using solar energy from the home solar system. Besides, it uses LEDs to indicate the status of the repellent system. \u0000Results: The generated ultrasonic signal is observed on the oscilloscope screen and its’ value is exhibited on the LCD screen to evaluate the system performance. Testing confirms that the system can drive away mosquitoes within its 3 m surroundings in 2-3 minutes.
