This was a multicenter, double-blind case–control trial across three centers in India which enrolled a total of 1095 adults in two groups—590 participants with diabetes and 505 healthy controls. The primary outcome was the difference in thermography readings between the two groups. The secondary outcomes included the correlation of thermography readings with HbA1C, considered the gold standard. The thermography readings at all seven sites were lower in people with diabetes as compared to the control group. However, this attained statistical significance across four sites—forehead (Δmean difference = 0·34, 95% CI [0·14–0·53], medial canthus of both eyes (Δmean difference = 0·48, 95% CI [0·31–0·66], pinna of both ears (Δmean difference = 0·53, 95% CI [0·28–0·73]) and palmar surface of both hands (Δmean difference = 0·28, 95% CI [0·02–0·53]). In addition, thermography readings showed a significant negative correlation with HbA1C values across these four sites, although the strength of the correlation was weak. This study sheds light on the utility of thermography for large-scale noninvasive diagnosis of diabetes mellitus. Future research should focus on large-scale community screening of early asymptomatic disease as well as micro- and macrovascular complications to define its exact role in the overall disease management pathway.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 5","pages":"561 - 569"},"PeriodicalIF":1.2,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139645176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to finite sources of fossil fuels and rise in exhaust emissions resulting into global warming, the researchers have shifted to the petroleum fuel alternatives. The present work considers the different engine input factors (i.e., blending ratio and load) while evaluating the different performance parameters (brake thermal efficiency), combustion (brake-specific fuel consumption), and emission parameters (nitrogen oxide, carbon monoxide, and hydrocarbon) while using waste cooking oil biodiesel in a four-stroke single-cylinder diesel engine. A hybrid RSM coupled with NSGA-II technique has been considered for optimizing the performance, combustion, and emission characteristics. The novelty of this work is the application of NSGA II, which has been successfully applied in the simultaneous optimization of brake-specific fuel consumption, brake thermal efficiency, and different emission parameters, viz. carbon monoxide, nitrogen oxide, and hydrocarbon. Five optimum combinations have been evaluated from the 39 Pareto solutions set, and their confirmation tests have also been conducted. From the analysis, the brake thermal efficiency of 31.29% and brake-specific fuel consumption of 0.261 kg/kW-hr along with values of the emissions such as nitrogen oxide: 63.470 ppm, carbon monoxide: 0.085% and hydrocarbons: 20.724 ppm have been achieved. The results are very much within the acceptable limits which confirms the feasibility for the use of waste cooking oil biodiesel in the four-stroke diesel engine.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 5","pages":"515 - 520"},"PeriodicalIF":1.2,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
