The research emphasizes the crucial nature of protecting and managing groundwater quality in this region, as it is vulnerable to contamination. The spatial distribution patterns of groundwater quality in the area are depicted in this article. The physicochemical properties of fifty (50) water samples are directly related to residents' environmental and health status. The physicochemical parameters measured using the American Public Health Association procedure (APHA)—including pH, conductivity, total dissolved solids, sulphate, nitrate, sodium, chloride, and total hardness—were below the limit established by WHO (2011). Iron in most boreholes is found to be above the WHO standard for drinking water. With the help of ArcGIS software, these results were modeled using the inverse distance-weighted method to provide the spatial pattern of groundwater. The spatial distribution map delineates groundwater suitability zones of 55% and unsuitability zones of 45% for groundwater extraction of water points in yenagoa affected by high iron content. As a result, GIS is a powerful tool for making critical decisions in waste management-related issues, such as identifying areas where waste management practices may be deficient and allowing for targeted initiatives to improve waste management practices and reduce waste's negative impact on the ecosystem and public health.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84952815","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}

However, some clinical complications that are inherent to the treatment may occur, such as fracture of instruments inside the conduit, perforations, and anatomical anomalies. When this occurs and it is not possible to carry out an endodontic intervention, opt for endodontic surgery. The aim of this study is to report a clinical case of endodontic surgery in a lower molar with a fractured file and resorption process. A patient was assisted who had a necrotic dental element, symptomatic, mesial root with fractured file and distal root with resorption process proven in the initial radiograph. In the first session, anesthesia, access surgery, absolute isolation, irrigation with 2.5% sodium hypochlorite were performed and an attempt was made to remove the fractured instrument with an operating microscope and an ultrasound insert, but this was unsuccessful. In this way, the dental element instrumented with rotary files logic 25/05, dried and filled with thermoplasty technique, using bioceramic cement. In the second session, endodontic surgery was performed with removal of the fractured instrument. A 2-month follow-up was performed, analyzing the pathology and symptomatology regression. The patient was asymptomatic and undergoing tissue repair in the mesial and distal root. It is possible to conclude with this clinical case that endodontic surgery is feasible in cases of fractured instrument and resorption process, thus allowing the remission of the pathological process, paralysis of the infectious process and permanence of the function and aesthetics of the dental element.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":"PP 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84303916","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 goal was to understand the close connection between fluctuating temperatures and elephant movement toward human habitations. A questionnaire was utilized to gather insights from 53 individuals, primarily adults residing around Lékédi National Park. Statistical analysis of the collected data revealed a significant correlation between the percentage of individuals noticing changes in Moabi tree productivity and variations in mean annual temperature. The mean annual temperature had increased by +0.06°C over the two consecutive 5-year intervals between 2011 and 2020 (study period). The survey indicated that 56.6% of respondents perceived the Moabi fruit harvest as average in the last two years, and around 90% of people had witnessed their own or a relative’s field being devastated by elephants during the same period. Notably, 96.23% of respondents believed that present-day elephants are getting closer to human dwellings, compared to 3.77% who thought they were moving farther away. The lack of available Moabi fruit would encourage elephants to venture into secondary forests, thereby escalating the risk of human-elephant conflict.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78584126","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}

This article studies the PID（Proportion Integration Differentiation）controller design method and fuzzy PID controller design method based on the Ball & Beam system, aiming to achieve effective control of system stability and performance. Firstly, a force analysis was conducted on the Ball & Beam system, and a mathematical model was established based on the Lagrangian equation, providing a foundation for the subsequent design of control strategies. Next, we conducted an analysis of stability and performance indicators, including overshoot, adjustment time, etc., to evaluate the performance of the two PID controllers. Finally, the optimal PID controller is determined by adjusting their respective control parameters, and the accuracy, speed, and stability of the proposed algorithm and model are verified through their corresponding response curves. The simulation and experimental results show that the fuzzy PID controller can quickly stabilize the ball at the target position compared to the conventional PID controller and has good practicality, stability, rapidity, and accuracy.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135053708","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}

In order for farmers to have greater productivity, more profits and exports, they started to use pesticides on their plantations, making excessive use of this product. Knowing the damage that this product can cause, the objective of this work was to compare the research published to date on the possibility of the presence of pesticides in food and natural resources, in addition to their possible influences on the environment and the health of the population. The method used to develop this work was a bibliographical review on the topic of pesticides, the damage to the environment and human health due to their intensive use. The results obtained from the authors cited on the intensive use of pesticides are the risks of diseases in men such as cancer, infertility, impotence, miscarriages, among others. There is also a risk of contamination of breast milk and the birth of babies with autism. In the environment, there is contamination of soil, water, air, food and malformations and death of animals. In order to minimize the impacts of pesticides on the environment and human health, the correct use of this product is necessary, using them according to the leaflet, in the correct dosage, in addition to the correct disposal of packaging and aerial spraying at the limit according to the relevant law.

In addition to these, there are efforts to search for increasingly ecologically correct processes and products. Coming to common sense and delivering a quality product, on time and that generates the least amount of waste and impact on the environment is the current challenge. The article shows two systems, lean manufacturing and its tools to help reduce waste, and Cleaner Production, which seeks to optimize resources in favor of the lowest impact to be generated. In addition to these, it aims to show the benefits generated by them when applied correctly. The article was developed through qualitative research, with searches carried out for case studies and articles, through exploratory and bibliographical research. Lean Manufacturing aims to highlight and eliminate all waste, whether in the productive area or in the administrative area, Cleaner Production aims to identify the generation of impacts and highlight them in the search for the elimination of generation. As a result, there is a similarity between both methodologies, but with different focuses, one more structured with defined methodologies and analysis and implementation tools, the other with step-by-step implementation, but somewhat superficial.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85487977","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}
