Additionally, it is confirmed that the mass of amine mist is larger than that of amine vapor and have a great influence on amine emission. However, it is very difficult to reduce the amount of amine mist with conventional method like a packed bed tower. In this study, we have designed and constructed a bench-scale plant and evaluated effective countermeasures to reduce amine mist for mitigation of amine emissions. Firstly, we have confirmed how the test conditions affected characteristics of amine mist in mist generation section. Then we could succeed in generating simulated amine mist like the actual amine mist derived from MEA or TS-1 at the outlet of the absorber tower in Mikawa pilot plant. Secondly, we have prepared two demister sets (coarse and fine) with two different diameters for each and measured number concentration of amine mist in this mist reduction section. Then the mist removal efficiency of fine demister is very high compared with that of coarse demister. Additionally, the removal efficiency of over 1 μm is approximately 99% in the case of fine demister. Finally, we have checked pressure drop regarding gas velocity passing through a coarse or fine demisters. As a result, the value of pressure drop with fine demister was about ten times as large as that of coarse demister.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126434809","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 capacity demands both opacity respect—preserving a gap between the self we present and the self we conceal—and an ability to call into question practices that are ethically wanting. Pushed to its limit, the smooth optimisation of our environment may prevent us from experiencing many of the tensions that otherwise prompt us to reconsider accepted practices. An optimally personalised world may not ever call for any ‘action’ as Hannah Arendt describes it.Can systems be designed to personalise responsibly? Greater time and research needs to be invested in designing a range of viable ‘perspective widening’ tools, as many such tools either burden users with little guarantee of meaningful engagement, or underestimate the extent to which individuals’ preferences are themselves malleable. Any approach that tries to predict what users might like, or what might change their views, risks the same pitfalls as any other form of personalisation. Instead, we argue that the most promising avenue is to push for diverse uses of newly developed systems, and measure those systems’ success at least partly on that basis. Inviting appropriation and repurposing would help keep users engaged in systems of data collection and profiling. This will not be a straightforward task: sometimes it will be in tension with traditional measures of success and performance. Yet the increasing integration of algorithmic systems in society requires us to widen our understanding of agency beyond a narrow, decontextualised focus on passive consumption preferences.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134025247","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}

Most of the rainwater is wasted due to the runoff in absence of proper water harvesting plan. It is required to develop a technique to harvest rainwater from all possible ways. It is easy to implement the project of rainwater harvesting system on National Highways. Longitudinal as well as cross-sectional slopes of National Highways are already very accurate to channelize the rainwater for harvesting. In this study, an integrated approach for assessing the rainwater harvesting capacity in minimum cost by using GIS and field survey approach for the study area on National Highway 27, Udaipur bypass. In a pilot study of 5 km segment of National Highway 27, it is found that 65 million liters of water can be harnessed for future use by 2000 villagers for about 240 days with per capita consumption of 135 lpcd (litre per capita demand). RS and GIS provide a good opportunity to gain a better understanding of contour pattern, natural and manmade profiles. The result indicates the application of GIS techniques help for conducting detailed field survey for planning the proper drainage system along the highways to store rainwater in the nearest reservoir. The socioeconomic survey was also conducted to select a good insight into the local situation.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114484972","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}

Smart (technological) hospitals represent long-termed investments where public and private players interact with banking institutions and eventually patients, to satisfy a core welfare need. Characteristics of smart hospitals are critically examined, together with private actors’ involvement and flexible forms of remuneration. Technology-driven smart hospitals are so complicated that they may require sophisticated PPP. Public players lack innovative skills, whereas private actors seek additional compensation for their non-routine efforts and higher risk. PPP represents a feasible framework, especially if linked to Project Financing (PF) investment patterns. Whereas the social impact of healthcare investments seems evident, their financial coverage raises growing concern in a capital rationing context where shrinking public resources must cope with the growing needs of chronic elder patients. Results-Based Financing (RBF) is a pay-by-result methodology that softens traditional PPP criticalities as availability payment sustainability or risk transfer compensation. Waste of public money can consequently be reduced, and private bankability improved. In this study, we examine why and how advanced Information Technology (IT) solutions implemented in “Smart Hospitals” should produce a positive social impact by increasing at the same time health sustainability and quality of care. Patient-centered smart hospitals realized through PPP schemes, reshape traditional healthcare supply chains with savings and efficiency gains that improve timeliness and execution of care.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127423784","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}
