This research addresses the gap on the limited work published on the pollutants present and dissolved in the water. Relatively little attention has been given to the study area, where different shipping operations may have considerable impacts on the water quality in the port environment. Based on the standards set by the Taiwan International Ports Corporation (TIPC), pH and DO are within the permissible values. DO was markedly lower during high tide, which was consistent with the findings of other researchers. The concentration of mercury, arsenic, and chromium were all below the detection limits of the measuring equipment used in the research. Water quality is significantly affected by the location of sampling area, whereas the inner port area showed relatively higher level of contamination compared with the measurements taken at the outer port area. Based on the independent samples Mann-Whitney U test conducted, tidal condition does not significantly affect the distribution of measurements of the water quality parameters.","PeriodicalId":394576,"journal":{"name":"Proceedings of the 8th World Congress on New Technologies","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127490022","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}

Among the biodegradable biopolymers, the ones based on polysaccharides like chitosan have presented great interest. After cellulose, chitosan is produced by chitin’s deacetylation, the most bountiful natural polysaccharide. The The FTIR analysis confirmed the characteristic peaks related to chitosan and nanoparticles and the interactions developed between the components. The SEM/ EDX analyses confirm the presence of nanoparticles in the membranes’ structure and their relatively homogeneous distribution conferring the premises of using them as reproducible membranes for water purification applications. The TG/ DSC analysis on the subjected samples illustrated the thermal behaviour and the composition very close to the theoretical ones, again confirming a good homogeneity of the samples. Following the antimicrobial assessments, the composite membranes have inhibited the adherence of the tested microbial strains. Therefore, E. coli ATCC 25922 and Citrobacter sp. were the most sensitive to the as-developed membranes. Also, the composite membranes had moderate antimicrobial activity against Gram-positive strains resistant to antibiotics ( E. faecalis VRE 2566 and S. aureus MRSA 5578), which indicates that the as-presented composite membranes showed great perspective in developing membranes for water purification applications.","PeriodicalId":394576,"journal":{"name":"Proceedings of the 8th World Congress on New Technologies","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123397394","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}

Biofene® (or trans-β-farnesene) is a synthetic biology derived product using yeast fermentation of sugarcane. This production originates spent broth, an aqueous waste stream typically applied to land by fertirrigation. On one hand, spent broth contains recoverable added-value compounds; on the other hand, an improper disposal of this waste stream could result in negative effects and give rise to environmental concerns. Hence the importance of implementing the bio-waste refinery and circular bio-economy concepts for recovering high-value bio-products. Cosmetic industries are committed to find natural, sustainable, and functional ingredients meeting consumer’s and entities rigorous demands. Spent broth may be a source of such ingredients. Thus, the objective of this work was to assess the fractionation of the spent broth stream from Biofene® production to obtain a concentrated nutrient rich extract with potential application on cosmetics. The spent broth’s was pretreated for mineral recovery, using a chemical free process developed within the Alchemy Project. The pre-treated spent broth was then fractionated in a cascade membrane filtration process, in an attempt to recover a rich peptide and minerals fractions. This process comprised three steps: microfiltration (MF), ultrafiltration (UF), and nanofiltration (NF). The composition of the obtained fractions was monitored in terms of total proteins and minerals contents, amino acids profile, and antioxidant capacity. All experiments were done in a crossflow filtration unit (Sepa CF, Sterlitech), coupled to a pump (G13-X, Hidra-Cell®) applying a feed recirculation of ca. 250 L/h. Microfiltration aimed to the clarification of the pre-treated spent broth, fermentation spent broth stream. The product preliminary characterization reveals interesting nutrients and bioactivities, suggesting a potential application in cosmetic industry.","PeriodicalId":394576,"journal":{"name":"Proceedings of the 8th World Congress on New Technologies","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127020383","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 low-resource settings or field settings, the ability to perform surgeries is often limited by a lack of surgical instruments. On-demand manufacture of surgical instruments via 3D printing may offer a low-cost, reliable, convenient solution for provision of necessary care, particularly during trauma or emergency situations. The global coronavirus-19 disease pandemic has emphasized the need for rapid manufacturing of surgical instruments at the point of care, as the pandemic has often limited patient access to hospitals, due to measures to minimize the spread of infectious disease. Moreover, the ability to 3D print surgical instruments is a priority for enabling surgery during space missions. Recent progress has been made on 3D printing of commonly used surgical instruments from plastics. Important surgical tools such as forceps, scalpel handles, needle drivers, Army/Navy retractors, and hemostats have all been 3D printed, with typical print times on the order of hours. This paper assesses the current status of 3D printing of surgical instruments. The review will include 3D printing methods, raw materials, design times, print times, sterilization methods, and the types of surgical instruments that have been successfully printed. In addition, the results of mechanical testing and simulated surgical testing of 3D printed surgical instruments will be described. Finally, avenues for future work will be identified, including the need for faster print times, and the necessity for producing more intricate instruments via 3D printing. © 2022, Avestia Publishing.

However, the presence of heavy metals is also detected in CWs. This paper presents the water quality monitoring results of a CW in Melbourne, Australia. A statistical analysis has been undertaken to determine the correlation of heavy metals with TN, TP and TSS. The analysis revealed that the treatment performance did not comply with the best practice management guidelines and the wetland is experiencing significant metal pollution. The results showed that TN and TP concentrations are negatively correlated and TSS are strongly correlated with the concentration of metal pollutants including Al, Cu and Fe. Meanwhile, significant correlations are discovered between metals such as Zn and Cu, Al and Cr than between the common pollutants. As this is a preliminary analysis, further investigations are needed to validate the relationships. It is envisioned that the outcome of this research will assist CWs owners and managers to assess the effectiveness of CWs in reducing the levels of not only the common three pollutants but also heavy metals.","PeriodicalId":394576,"journal":{"name":"Proceedings of the 8th World Congress on New Technologies","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130910495","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 research investigates the number of reported adverse events related to the use of prescription opioids and opioid overdose treatments during the COVID-19 pandemic, lending further insight into the impact the COVID-19 pandemic has had on the opioid epidemic. We hypothesized that adverse events for both prescription opioids and opioid overdose treatments rose during the COVID-19 pandemic, due to isolation and lack of access to healthcare services. Using data from the Food and Drug Administration Adverse Event Reporting System (FAERS), we analyzed the number of adverse drug events (ADE) in the years 2020 and 2021 compared to 2019, specifically for the medications Naloxone(G), Naloxone Hydrochloride(G), Oxycodone(G), Oxycodone Hydrochloride(G), and Oxycontin(P). We also analyzed the most commonly reported types of adverse reactions and the age of the reporters. The data reveals an alarming spike in the number of ADEs attributed to Naloxone(G) from 2019 to 2020, increasing by 148% and then another 29% in 2021. Similarly, the number of ADEs reported for Naloxone Hydrochloride(G) nearly rose four-fold from 66 to 246. For the prescription opioid Oxycodone(G), there was a 78% increase in ADEs from 2019 to 2020. More concerningly, there was a 434% spike in the number of ADEs for Oxycodone Hydrochloride(G) and more than thirteen-fold the number of cases in 2020 than 2019 for Oxycontin(P). Finally, we found the most commonly reported reactions were \"overdose,” \"drug dependence,” \"drug withdrawal syndrome,” and \"drug abuse”;the 18–64-year-old age group reported the majority of the cases. These results highlight the need to increase focus on the opioid epidemic, specifically monitoring the use of prescription opioids. © 2022, Avestia Publishing.
