The material was subsequently employed as adsorbent for the efficient capture of o-nitrophenol (ONP) from aqueous solutions. With the change of the ratio of MgO template to waste PET, the prepared porous carbon has controllable specific surface area. The sample of WPC-1.5 exhibits a remarkable specific surface area of 885.99 m 2 /g. Static adsorption experiments demonstrate that this material possesses a substantial adsorption capacity for ONP, achieving a value of 474 mg/g. The WPC-1.5 was characterized by scanning electron microscopy, BET and adsorption kinetic and equilibrium isotherms evaluation.","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"536 1","pages":"02015-02015"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.e3s-conferences.org/articles/e3sconf/pdf/2024/66/e3sconf_eppct2024_02015.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most research on xenobiotics has focused on the gut microbiota while neglecting other body sites, yet over two-thirds of pharmaceuticals are primarily excreted in urine. As a result, the urinary microbiota is exposed to many xenobiotics in much higher concentrations than in the gut. Microbial xenobiotic biocatalysis in the bladder has implications for urinary tract infections and the emergence of antibiotic resistance. However, we have limited knowledge of biotransformations catalyzed by the urinary microbiota. In this perspective, we investigated differences in physicochemical conditions and microbial community composition between the gut and urinary tract. We used a comparative enzyme class mining approach to profile the distribution of xenobiotic-transforming enzyme homologs in genomes of urinary bacteria. Our analysis revealed a discontinuous distribution of enzyme classes even among closely related organisms. We detected diverse amidase homologs involved in pharmaceutical and dietary additive biotransformation pathways, pinpointing microbial candidates to validate for their involvement in xenobiotic transformations in urine. Overall, we highlight the biocatalytic potential of urinary tract bacteria as a lens to study how the human microbiota may respond and adapt to xenobiotic inputs.</p>","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"1 1","pages":"424-431"},"PeriodicalIF":1.2,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79862503","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 founders of EACEF are Prof. Dr.-Ing. Harianto Hardjasaputra, Professor of Pembangunan Jaya University – Indonesia, and Prof. Dr.-Ing. Karl-Heinz Reineck, Senior Lecturer of the University of Stuttgart-Germany. Both would like to further their many years of cooperation with their international colleagues (especially those from Europe and Asia) through EACEF. EACEF is a forum to promote cooperation and understanding between European and Asian countries, focusing on Civil Engineering expertise. EACEF will play an essential role as the bridge between these two continents in linking European and Asian Civil Engineers, especially those committed to sustainable development and environmentally friendly buildings. The conference has been conducted biannually since 2007 in Jakarta, Indonesia, and has been conducted in several countries as well. The details of previous conferences can be found at https://eacef.com/. As the biannual conference, the 8th EACEF conference should be conducted in September 2021. However, due to the COVID-19 pandemic, the EACEF committee decided to postpone the 8th EACEF conference to October 2022.\u0000 This Proceeding contains papers based on invited keynote speeches and oral presentations at the 8th EACEF conference 2022 “Advanced and Innovative Technology for Sustainable Infrastructure”. The event was held on October 4th-5th 2022 at OST Eastern Switzerland University of Applied Sciences, Switzerland and on October 12th-13th at University of Atma Jaya Yogyakarta, Indonesia. The event covered several topics: “Structural Engineering”, “Construction Material”, “Construction Management”, “Infrastructure Engineering”, and “Geotechnical Engineering”.\u0000 The conference started with plenary sessions of keynote speakers on October 4th-5th 2022 (online presentation) and followed by technical sessions on October 12th-13th 2022 (hybrid presentation) which were divided into three parallel sessions. Each keynote speech took 30 minutes for presentation and discussion while speakers in technical sessions were given 10 minutes and 5 minutes for presentation and discussion, respectively. There was a total of 13 keynote speakers and 64 presenters which consist of both academicians and professionals from Indonesia as well as other countries such as China, Germany, Japan, Switzerland, Morocco, United States of America, Malaysia, Brunei Darussalam, United Kingdom, and Australia.

In parallel with traditional reference texts, online internet search via Google Image Search (GIS) is commonly used and offers an accessible fund of reference images for ophthalmology trainees seeking rapid exposure to images of retinal pathology. However, the accuracy and quality of this tool within this context is unknown. We aim to evaluate the accuracy and quality of GIS images of selected retinal pathologies. <b>Methods</b>  A cross-sectional study was performed of GIS of 15 common and 15 rare retinal diseases drawn from the American Academy of Ophthalmology residency textbook series. A total of 300 evaluable image results were assessed for accuracy of images and image source accountability in consultation with a vitreoretinal surgeon. <b>Results</b>  A total of 377 images were reviewed with 77 excluded prior to final analysis. A total of 288 (96%) search results accurately portrayed the retinal disease being searched, whereas 12 (4%) were of an erroneous diagnosis.

Under the deregulated electricity market, IES operator gains profits by providing customers with energy service, including electricity, heat or cooling energy. With the deepening of market reform, higher penetration rate of renewable energy, economic risks embed in the IES. Based on this, an optimal scheduling model of regional IES considering uncertainties is proposed, aiming at maximizing the profits. Scenario analysis method has been adopted to model the uncertainties: Markov-Chain-Monte-Carlo (MCMC) sampling method, which has a better performance in fitting the probability distribution, is utilized to generate scenarios; K-means clustering method is applied to narrow down the sampling sets. By replacing the parameters in the deterministic model with the sampling sets, a series of optimal results can be achieved. The case study shows that the cooling storage tank can improve the economic benefits about 4.97% by converting electricity to cooling energy at lower price period and releasing energy at peak hours. Besides, through the proposed optimization model, operators can have a straight understanding of the venture brought by the uncertainties and a more reliable scheduling result is formed for reference.","PeriodicalId":11445,"journal":{"name":"E3S Web of Conferences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42220935","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}
