About 350-400 metric tonnes of municipal solid waste is generated by the city, the major portion of which is constituted by organic waste (40%), inert waste (25%), plastic (15%), textiles (13%), and paper (7%). Inefficient waste collection, uncontrolled waste dumping, and absence of waste segregation at source have subjected the environment and human health to very serious risks. This review highlights waste generation and disposal practices and the scope for recycling and waste-to-energy (WtE) in the context of Jammu City. Recent attempts involving Integrated SWM facilities in Kot Bhalwal and bio-remediation projects of Jammu City appear to be a little promising in terms of solving issues regarding the accumulation of waste. However, considerable challenges remain, such as a low level of awareness among members of the public, minimal infrastructure for the practice, and carelessness in the execution of the policies. Therefore, improving waste segregation at source, recycling facilities upgrading of landfills with scientific treatment methods, and mass awareness campaigns are essential for ensuring sustainable waste management in Jammu City. In addition, artificial intelligence (AI) can also present a transformative solution by optimizing waste collection routes, automating segregation, and enhancing recycling. Further, AI-powered smart bins, WtE technologies, and detection of illegal dumping can improve efficiency and sustainability. Integrating AI with community engagement and policy measures such as incentives for eco-friendly practices can drive Jammu toward a smart, data-driven waste management system, reducing pollution and conserving resources. Finally, the imposition of fines on businesses for improper disposal and penalty on people involved in improper disposal practices can enhance the efficiency of waste management as well.","PeriodicalId":39371,"journal":{"name":"岩土工程学报","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://assets.cureusjournals.com/artifacts/upload/review_article/pdf/5381/20251029-190930-o6uoa7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147900972","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}

Salt is produced with three types of qualities which include salt quality one, salt quality two, and salt quality three. Salt quality three is salt that has the lowest quality such as the color of salt that is dull and not consumed. These three quality salts are usually used for agriculture and agriculture. Improvement of salt quality is done by doing the process of recrystallization which then the results of the recrystallization process are measured by looking at changes in NaCl content and salt color. This research was conducted in West Pademawu, Pademawu District, Pamekasan Regency as a place to recrystallize salt and Village Unit Cooperatives \"Karya Sakti\" Montok Larangan District Pamekasan Regency as a place to conduct laboratory tests on the content of NaCl. The analysis used to determine the improvement in salt quality is the content of NaCl and the color of salt. The research design used is a complete random design (RAL) factorial. The use of the factorial RAL method has three factors, namely, the first factor is the composition of the solution with two levels, namely 15% and 20%. The second factor is the temperature with two levels is 110oC and 120oC. The third factor is the length of boiling with two levels, namely one hour and two hours. Data is analyzed by conducting Analysis Of Variance (ANOVA) tests and further tests.. The results of the analysis showed that no significant influence was influenced by the interaction factors between the composition of the solution, temperature, and length of boiling of NaCl and salt color. But from the results of the process of recrystallization of NaCl salt content and salt color experienced an increase that originally had NaCl content of 94,59% to 98%. Similarly, the color of salt has increased which was originally at the 4th level then increased to level 2. With the process of recrystallization of salt, salt that was original of three qualities increased to two qualities.","PeriodicalId":39371,"journal":{"name":"岩土工程学报","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83333661","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 work, three types of additives (molybdenum disulphide, fumed silica, and polytetrafluoroethylene) were tested as thermal stability additive. The grease was characterized using ASTM International standards and SKF’s Grease Test Kit. Based on grease characterization, the addition of additive was found slightly affecting the grease properties. Fumed silica was observed able to improve the grease thermal stability by 3.6%.

Through a numerical case, change of safety factor in the whole process of the pile driving is analyzed. And the effect of pile diameter, slope angle and distance between pile and slope top on the change of safety factor of slope is discussed. The results show that the pile driving force and the plastic zone at pile top have an adverse effect on slope stability, which leads to a decrease in the safety factor, while the anti-sliding effect of the pile has a positive contribution to the slope stability, especially when the end of pile is below the sliding surface. The safety factor decreases significantly with the increase of the pile diameter, and it significantly increases after the pile end penetrates through the sliding surface. The greater the slope angle, the smaller the safety factor after pile driving. The safety factor drops more slowly with the increase of the distance of the pile away from the slope top, and the effect of the plastic zone on the safety factor also gradually decreases. The pile driving will not affect the stability of the sliding surface when the pile is far from the top of the slope. The results may provide some guiding significance and reference value for the design and construction of static pile driving adjacent to slopes.","PeriodicalId":39371,"journal":{"name":"岩土工程学报","volume":"31 1","pages":"1720-1726"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82458094","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, the solutions obtained from the approaches are in general limited to a designated slope or the same kind of slopes. It seems that a wide applicability of the solutions in their present form is rather difficult. Based on the kinematic theorem and the assumption of combined log-spiral rotational failure mechanism, the integral formulation for expressing the rate of external work rate due to soil weight and seismic loading is derived under the framework of pseudo-static method considering the complex geometrical configurations and the multilayer soils in slopes with multi-row anchors. Further, the work-energy balance equation is established, and the analytical expressions for the global factors of safety (FS) and the yield acceleration coefficient of anchored slopes are obtained by using the strength reduction technique combined with the optimization method. Moreover, the permanent displacement with Newmark's method is also solved. Several representative examples are employed to validate the analytical solutions, and some comparisons of the FSs and the corresponding critical sliding surfaces obtained by various methods are also made. The results show that the analytical approach can yield the high-accuracy solutions and is widely applicable to the seismic stability analysis of complex slopes with multi-row anchors.

It is of great importance to consider the rocking vibration of the foundations in the lateral vibration analyses of wind turbine structures. In order to avoid resonance, which is very dangerous to high structures, the first-order natural frequencies of the wind turbine structures are always designed as away from 1P and 3P(2P) ones, so it is very important to calculate the natural frequencies of the wind turbine structures accurately during the design procedures. At present, the methods for calculating the dynamic characteristics of the wind turbine structures, including the natural frequencies, are usually based on the assumption of base fixity. Inaccuracies may occur in these methods for not considering the impedance of foundations. In this work, the coupled horizontal-rocking impedance of the pile group is derived and its impact on the resonance characteristics of the wind turbine structures is studied. First, a simplified method to determine the horizontal-rocking impedance of the pile group with dynamic Winkler model is proposed and verified by comparison against some published accurate solutions. Second, a lateral vibration equation for the wind turbine structures is derived with the consideration of the foundation impedance. Finally, through an example of wind turbine structure, the influence of the foundation impedance on the resonance characteristics of the structure is studied, and the proposed simplified method is verified by use of the finite element method.","PeriodicalId":39371,"journal":{"name":"岩土工程学报","volume":"28 1","pages":"286"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90913605","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}
