Uncertainty is an important factor that needs to be considered while analyzing the performance of any engineering *** order to quantify uncertainty,fuzzy set theory is frequently used by most of researchers,including energy system *** to the classical reliability theory,component lifetimes have crisp parameters,but due to uncertainty and inaccuracy in data,it is sometimes very difficult to determine the exact values of these parameters in real-world *** overcome this difficulty in the current research,failure and repair rates were taken as triangular fuzzy numbers to determine the fuzzy availability of a system undergoing calendar-based periodic inspection subject to multiple failure modes(FMs).It was assumed that each component in the system had an exponential failure rate and repair rate with fuzzy *** FMs were explicitly taken into account when a functional state of the system was *** FM had a random failure *** the occurrence of any failure,a random time was selected for the relevant corrective repair *** proposed research was studied for one of the major sources of green energy,namely a wind turbine system wherein all the derived propositions have been implemented on it.

In this extensive investigation,the impact of borax decahydrate as a fuel additive in a diesel single-cylinder engine was rigorously *** decahydrate was introduced at concentrations of 5,15,25 and 35 g in 500 ml of biodiesel,forming five unique fuel mixtures with conventional diesel:90%diesel+10%spirulina biodiesel(Sb10),Sb10+1 g borax decahydrate(Sb10b1),Sb10+3 g borax decahydrate(Sb10b3),Sb10+5 g borax decahydrate(Sb10b5)and Sb10+7 g borax decahydrate(Sb10b7).The investigation encompassed four diverse loading conditions and yielded insightful ***,at full load,Sb10b3 exhibited a higher cylinder peak pressure than diesel,reaching 69.25 *** release rate profiles demonstrated superior efficiency for Sb10 at 50%load,with a cumulative heat release rate of 950 J/°CA,which is lower than the 1050 J/°CA of *** intensity(KI)evaluations revealed that,although Sb10 and Sb10b1 exhibited higher KI than diesel at full load due to elevated peak pressure,Sb10b7 showed no knocking across all loads,indicative of reduced in-cylinder *** meticulous numerical analysis emphasizes the potential of borax decahydrate as a catalyst and enhancer,providing valuable insights into the combustion dynamics of these alternative fuel blends and their viability for sustainable and efficient engine *** summary,out of all the blends,Sb10b3 could be a potential diesel fuel replacement fuel for compression-ignition engines.

位于印度莫拉达巴德的国际营养学院（会）始建于1986年，其基础是印度营养学院（会）。它有两个职能：一是类似于营养学研究所性质的科学研究和教育的实体，二是类似于营养学会性质的群众性学术团体。学术的专业性质侧重于医学营养学，工作的对象以印度为基点，着眼于第三世界。它通过多年的实地研究后指出，由于第三世界居民原来的饮食等情况的特点，对那些发达国家饮食营养指南的移植要慎重。其研究实体是营养学研究中心，研究重点是心血管疾病和老年营养，现在正在进行欧共体等支持的关于老年人的生活饮食习惯与疾病谱的研究和抗氧化营养素与动脉粥样硬化的研究等，这些研究工作又与国外多个研究机构合作，现已初见成效。国际营养学院（会）每二年组织一次国际性学术会议，今年7月份在加拿大班夫举行第六届世界临床营养会议，主题是抗氧化剂与疾病。
