The quick method with gas sensor detection and colorimetric ion identification using a commercial Quantofix kit, as well as precipitation with AgNO3, offered preliminary information completed by Fourier Transform Infrared Spectroscopy (FTIR). Pollutants that reached the canal waters either by air (evaporation) or by discharges or through rainwater were analysed from the point of view of the degree of danger, sources of waste materials, as well as their circuit in the environment. Hydrogen cyanide, nitrites, nitro compounds, sulfites and sulphates, sulfonic tension-active compounds, peroxydes and hyperoxydes, azo-compounds, organic and inorganic acids of high corrosive potential, and Fe ions were generally the detected pollutants, each of them with specific harmful potential contributing as well in a cumulative effect to endangering human health directly or indirectly as environmental circulating contaminants.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135484669","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}

Inspection under UV light has shown that there was no previous retouching or overpainting on either painting. Microchemical tests identified the type of canvas. The radiograms indicated whether pigments with lower or higher atomic masses were used and how well the ground was rubbed among the threads of the canvas. A better penetration of the ground into the canvas and layers of oil dye that were applied to both sides of Painting 1 contributed to its better protection against high humidity. TLC revealed the type of ground on both paintings as a classic chalk-glue ground. The high humidity was responsible for the occurrence of metal soaps on Painting 2, which were confirmed by FTIR. The XRF analysis was used to describe the pigment palette, trace the causes of existing damages, and facilitate retouching. The results of this integrated diagnostic approach were used to optimise the conservation and better understand the features and techniques used in the creation of Bosnian socialistic artwork.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485150","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 2018, the Indonesian Government created a new policy to restore this watershed, named Citarum Harum, by putting together multiple actors to combat watershed degradation, including one unique actor, namely the Indonesian military. This anomaly had created a new pattern and dynamics in watershed restoration. Historically, Indonesia had a peculiar civil-military relationship with the past military government. This creates a unique framework for how actors currently react to military involvement. This article examines these phenomena and elucidates the effectiveness of military involvement in watershed restoration. The study was conducted by the Citarum Harum watershed restoration programme in West Java, Indonesia. This study used in-depth interviews and multi-level stakeholder influence mapping on multiple informants involved in the restoration. The findings indicate a good shift in actor relations that creates improvements in watershed restoration. However, several other conditions also arise from the military's involvement, such as overlapping authorities, incompetency on some technicalities, desynchronization, and a shift in public perception. These problems require some adjustment in the roles of both civil and military personnel in the restoration programme to optimise the military's involvement further.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135484820","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 solution is to utilise the potential of the Siak River and its historical heritage through waterfront city (WFC) management. Structuring a WFC based on a low-carbon concept can solve environmental problems by significantly reducing carbon emissions. This study aims to inventory, map, and evaluate the condition of the existing landscape, analyse public perceptions, and develop recommendations for a WFC with a low-carbon landscape concept. The methods used are historic urban landscape analysis, spatial analysis with land evaluation, community perception, and the preparation of recommendations. The results showed that the management of historical and cultural heritage is still poor. Based on the evaluation of land suitability, the WFC area has the potential to develop tourism, settlement, conservation, and pond areas with varying degrees of suitability according to the function of the area and several limiting factors. Through public perception, the level of enthusiasm of respondents is very high for applying the low-carbon landscape concept. Recommendations are made with the 15-Minute City Strategy through zoning and management programmes, namely tourism, mixed-use, conservation, and cultural preservation.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135484668","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 can be achieved by using modern methods, techniques, and tools (such as specific design methods and detailing, material mix design, specific material parameters, etc.) to redesign traditional Romanian housing entities, utilising existing construction materials and techniques predominantly of rural origin, empirically validated over the centuries, and reformatting them with modern scientific knowledge to generate a new model that is valid and compatible with current safety, aesthetic, and quality requirements. Earthen buildings, whether vernacular or constructed with qualified personnel such as craftsmen and traditional masons, use different techniques and construction technologies (rammed and poured, load-bearing walls, adobe bricks, mixed wood-earth structures, etc.) and were developed differently across the Romanian territory, depending on the climatic and relief zoning. By optimising these techniques and technologies, identifying their vulnerabilities and corresponding engineering solutions to counter them, and establishing pertinent fields of applicability in direct relation to their physical, mechanical, and durability characteristics and their evaluated bearing capacity, the conservation of the Romanian traditional housing legacy can be achieved. The opportunity of the proposed research is clearly connected to the current context of almost half of the Romanian population leaving for rural areas, including residential buildings made of earth. Supplementary, traditional building materials, like earth, clay, wood, etc., are based on primary natural resources, and they will generate ecologic housing concepts with a high degree of eco-efficiency in terms of use/re-use and recyclability, energy saving, and the health of the living space, in accordance with the general drive for resource savings and Circular Economy implementation in all fields, including the construction industry.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135485151","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}

MFCs were inoculated with PR3, acclimated with glucose then operated with bamboo hydrolysates containing different total reducing sugars as the anolytes. Total sugar consumption of the MFCs for electricity conversion varied from 76.25 to 96.30% after 48 hours of operation in bamboo hydrolysates. Results from electrochemical analysis showed that MFC with 9.0 g/L sugars from bamboo hydrolysates had better electricity production, with the maximum open-circuit voltage of 620 mV, current density of 1092.08 mA/m2 and power density of 91.16 mW/m2.

Due to differences in the raw material used and the manufacturing techniques, some of the current attempts at replicating Damascus steel have failed. The study of Damascus steel provided the opportunity to observe in detail the laborious process of manufacturing this material, which involves the free forging and welding of different layers of steel to obtain a particularly strong and durable final product. To carry out this research, high-quality materials were selected from a catalogue of steels, with a particular focus on achieving the best results. In this case, two types of steel were chosen to create Damascus steel: AISI 1095 and 15N20 steel. Both materials have been selected for their individual properties, such as mechanical resistance and durability, which contribute to the ultimate quality of Damascus steel. This rigorous selection of materials ensured a high-quality and authentic product. Throughout this study, a functional furnace was built capable of contributing to the welding and forging processes of these two different materials. This furnace played a crucial role in obtaining true Damascus steel. By applying a complex process of heating and forging and then repeating this process, the layers of steel were welded together, resulting in a final material that is extremely strong and has a unique aesthetic appearance. Processing and laboratory tests were carried out on the obtained Damascus steel to evaluate its mechanical properties, including the processing of the results using Autodesk Inventor Professional 2023 and simulation in Ansys 2023.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135484819","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}
