Many of them can be useful in biot echnology and pharmacy. Like other novel molecules from natural sources, they can help combat some global problems, such as antibiotic resistance and cancer treatment failure [1]. Extreme and unexplored environments may constitute a valuable source of fung i with high antimicrobial and anticancer potential [2]. Special attention can be paid to fungal guttates, which are known to contain a plethora of secondary metabolites [3]. In the study, we evaluated ten microscopic fungi isolated from coal -related enviro nments (coal lumps, mine water, and black soot) for their ability to secrete bioactive compounds into the guttation droplets. The isolates have been identified based on marker genes ITS, TEF1-α and TUB2 , and divided into genera: Aspergillus , Gliomastix , Penicillium , Simplicillium and Trichoderma . For optimisation of the guttation process, the fungi were grown on various media and incubated in temperatures 7, 17 and 27℃. The droplets formed at the top of mycelium were collected and subsequently subjected to bioassays. The antibacterial and antifungal activities of the exudates were evaluated using agar well -diffusion assay [4] against selected Gram - positive and Gram - negative bacteria, yeast and filamentous fungi. The anticancer activity was tested using MTS method [5], on the brain (LN - 229) and breast (MCF - 7) cancer cell lines. The guttation exudates secreted by Penicillium sp. MW - W400 - 5(F), Trichoderma sp. Cin -9, Simplicillium sp. MW - W600 - 40A and MW - W600 - 39 showed antibacterial activity towards Bacillus subtilis , Staphylococcus aureus and Yersinia enterocolitica , as well as antifungal effect against yeast Candida albicans . Moreover, the guttates of two fungal strains, Aspergillus MW - W600 - 11 and MW - W200 - 2, exhibited promising anticancer activity on the brain (LN - 229) and breast (MCF - 7) cancer cell lines in vitro . Additionally, they showed high selectivity, as they were significantly less toxic towards non-cancer cells, normal human dermal fibroblasts. The most active exudates are being subjected to further, chemical analyses. Chemical composition of their exudates is being investigated using liquid chromatography - mass spectrometry to identify potentially bioactive metabolites. While, genomes of the fungi were sequenced, and bioinformatic analysis in terms of bio synthetic genes detection is ongoing. Our current results showed that coal-related fungi could be a promising resource of new metabolites with antimicrobial and anticancer properties.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128744370","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}

Polypogon australis (Brong.) a native Chilean grass (Gramineae), is a facultative metallophyte that spontaneously colonizes abandoned mine tailing dumps. Genetic edition may be used to improve its metal tolerance and accumulation capabilities and thus to enhance its soil metal phytoextraction potential. At present, there are no protocols to carry out in vitro somatic embryogenesis and callus induction in P. australis which may lead to obtaining a complete gene-edited plant. In this study methodologies for massive in vitro plant tissue culture, callus formation and regeneration were studied by germinating and growing P. australis seeds in plates with Murashige and Skoog (MS) medium supplemented with sucrose and MS vitamins under controlled conditions (24°C, 4LS, 16/8; light/dark). A methodology for callus formation and plant tissue regeneration was carried out by cutting the seedlings in segments that were placed in plates with callus induction medium (CIM) and kept in darkness for 3 weeks, under control conditions (24°C, 0/24; light/dark). Results showed that both the medium and the growth conditions were effective for seed germination and early development of P. australis . A germination potential of 44-51% for P. australis seeds in the first 15 days was observed. After 7 days, callus development began only in the first segment corresponding to the hypocotyl. Therefore, for obtaining calluses of P. australis seedlings the optimal tissue was the hypocotyl. The percentage of callus formation was up to 38.9%.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124232320","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}

Silva","doi":"10.11159/icepr23.139","DOIUrl":"https://doi.org/10.11159/icepr23.139","url":null,"abstract":"Extended Abstract Plastics materials are known to release and spread organic contaminants in the environment. The generalized contamination by these materials occurs after adsorption and spreading of coexisting organic contaminants such as polycyclic aromatic hydrocarbons [1], by releasing plastics additives such as plasticizers, antioxidants, and flame retardants, and also by releasing products resulting from the degradation of the polymer matrix. As plastics are generally considered stable materials, this last contribution to environmental contamination has been overlooked. However, thought proceeding at low rates [2], plastics undergo degradation, which leads to formation/release of microplastics, nanoplastics and organic molecules. Plastics of all sizes are therefore exposed to degradation and potentially release organic compound in the environments contributing to their generalized contamination. The main abiotic degradation pathways include thermal oxidation and photooxidation. Both reaction types are radical processes, starting by the formation of carbon centred radicals on the plastics surfaces, which then react with oxygen leading to a cascade of reactions that ends with the incorporation of oxygen in the polymer structure. Released compounds result from multiple scissions of polymer chains. We have been studying the thermal and photochemical oxidation of microplastics on surfaces. Due to its exposure to both, sunlight and temperature in environmental conditions, we have been studying the degradation of these materials on beach sand surfaces. Both gas-phase released products and non-volatile compounds have been studied under thermal degradation and lamp irradiation conditions. Products released to the gas phase have been studied by SPME-GC-MS while the non-volatile compounds remaining on the surfaces have","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115614844","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}

Exposure to high levels of noise can cause many health problems in people of all ages. This study aims to measure indoor and outdoor noise quality and to observe student noise exposure at Mahindra University premises. The noise in classrooms and laboratories was recorded as a measure of indoor noise. In the afternoon sessions, the noise level in the classroom peaked up to 80 dB, which might be potentially dangerous to the students. The outdoor noise measurements were recorded at twelve different locations inside the University campus during working and non-working. The spatial distribution of the noise map was plotted. The frequency distribution curve suggested that the students were exposed to higher noise levels mainly in indoor areas than in the outdoors. The overall outdoor noise at the selected sites ranged from 53 to 65 dB when the traffic noise data at the main entry gate was excluded. The University has exceeded the maximum permissible noise level, which is 55 dB(A) suggested by WHO. This can result in noise pollution issues that annoy individuals, make it difficult to concentrate, hinder communication, and increase stress which could result in the poor academic performance of students.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134357415","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}

With limitations that COVID-19 had on the ability to track medical based data, a controversy on the effect of COVID-19 on the incidence of arrhythmic activity has been apparent. To determine the effect that pandemic had on the incidence arrhythmic activity, we studied adverse event trends of 4 anti-arrhythmic agents — propafenone, sotalol, amiodarone, and dronedarone. Extracting data from the FDA FAERS database, we concluded significant (p<0.05) decreases for propafenone (55.8% decrease) and amiodarone and dronedarone (16.9% decrease) from 2020 to 2021 as well as an insignificant decrease for sotalol (30% decrease). In response to suggestive decreasing trends, we proceeded with a cost-analysis to explore possible reasons behind sudden decreases in reported adverse events. Using the Medicare Part D database, data for costs between generic vs. brand-name for previously examined antiarrhythmic agents as well as associations between 30-day fills and adverse event reports was examined. For each of the agents, the brand-name agents had a significantly higher cost than the brand-name agents. Associations between adverse events and 30-day fills were demonstrated through R2 values, which resulted in values of 0.238 for propafenone, 0.796 for sotalol, and 0.651 for amiodarone and dronedarone. We concluded that cost did not have a significant effect on adverse event reporting. Overall, we recommend further study into the potential underdiagnosis and undertreatment of cardiac arrhythmias during the COVID-19 pandemic, which can have dangerous implications on the long-term mortality of individuals without the appropriate materials. To accomplish this, it is necessary to analyze 2022 adverse event data for various anti-arrhythmic agents to observe new or continuing trends.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"12 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114101465","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 this paper, a cost-effective 400 kWh thermal energy storage prototype for waste heat recovery at high temperature is tested over different charging and discharging conditions. The technology studied is based on the use of steel slag as thermal energy storage material and air as heat transfer fluid, in a packed bed reactor of 1 m 3 . Since the steel slag is a by-product of the steelmaking industry its cost is almost negligible, whilst its thermomechanical properties make it very attractive to store heat. The aim of the testing studies is to gather information regarding the heat exchange efficiency between the heat transfer fluid and the slag in different temperature levels, reproducing common industrial off-gas waste heat release. Finally, with these results a technoeconomic calculation approach is provided in the frame of a real waste heat recovery plant in the steelmaking industry, which confirms this technology as a very promising candidate for waste heat recovery solutions.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127763174","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}

Chromium Pillared Clay (CrPC) and Aluminium Pillared Clay (AlPC) were characterized using Scanning Electron Microscope, X ray diffraction, Energy dispersive X ray analysis and point of zero charge. The basal spacing increase in the interlamellar space confirmed the successful pillaring of clays. Acid Violet 19 (AV-19) dye was used as model adsorptive. Batch adsorption kinetic studies at ambient conditions revealed that the Pseudo Second Order (PSO) model could characterize the adsorption. The PSO rate constant for CrPC and AlPC were 0.0082 g/mg min and 0.0831 g/mg min, respectively. Langmuir isotherm fitted the equilibrium results for both the adsorption systems. The maximum adsorption capacity for the AV-19 dye on CrPC was 37.54 mg/g, while it was 24.33 mg/g for AlPC at ambient conditions. Thermodynamic analysis showed that the adsorption in both adsorbents was endothermic. The effect of pH on adsorption capacity suggested that electrostatic interactions were the primary contributing mechanism for dye adsorption on CrPC and AlPC. The results showed that the pillared clay adsorbents effectively treated the AV-19 dye-containing wastewater.","PeriodicalId":398088,"journal":{"name":"Proceedings of the 9th World Congress on New Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116750081","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}
