Abstract:The research paper focused on analysing in-Cylinder pressure, NOx formation of three different fuel combinations like EPEG 5.5, 6.5 and 7.5. The combustion process in a CI engine is divided into four stages. These are as follows, Ignition Delay, Rapid pressure rise or period of uncontrolled combustion, Controlled or constant pressure rise, burning of the expansion stroke. The variation of in-cylinder pressure with crank angle plotted concerning CA. Experimentally analysis of In-Cylinder pressure and heat release rate for the single-cylinder engine. NOx emissions of the EPEG7.5 fuel engine are 10.23% lower than the base fuel engine and 2.5% lower than the EPEG6.5 fuel engine. NOx emissions of the EPEG7.5 engine are 5.39% lower compared to the EPEG5.5 fuel engine. NOx emission of four ethanol test fuels follows a similar trend for without EGR mode when load increasing from 0.5 to 3.99 kW. In-Cylinder Pressure variation concerning crank angle for CFMs of 0.0256, 0.0327 and 0.0338 g/cycle. It can be observed from the experiments that the in- Cylinder peak pressure are attained near TDC, and the in-cylinder pressure with CA with 20% EGR mode is slightly less than without EGR.

Abstract:This research article focused on partially stabilised zirconium nano-surface coating for piston head and cylinder head surface to perform the experimental investigation on direct-ethanol blend with 7.5 percent by mass of polyethene glycol (PEG7.5) fuel injection in the high compression ignition (EDICI) engine. NOx and soot emissions should be minimised while still increasing fuel economy. EDICI also removes NOx and soot, resulting in a low equivalence ratio and low flame temperatures. For starters, reaction rates are related to temperature and equivalence ratio. Injection, evaporation, and mixing processes are also involved in combustion. The pollution rating of the engine is used to investigate the engine's effect on emissions. The primary goal of this research article is to improve the engine's thermal efficiency. Just one-third of the energy in the fuel is converted into proper operation. This investigation was carried out in order to carry out this mission. As opposed to the uncoated engine, the coated engine's BTE (BTB) improves. Thermal conductivity is poor in the ceramic coating. Productivity increased as a result of the reduction in a wall surface. The variance of BTE is determined by thermal conductivity. BTE is 6.1 percent for 8YSZ + Al2O3 + TiO2

Abstract:This topic is involved in the subsurface site investigation to characterize different soil formations with particular emphasis on the swelling characteristics of the clays. The data were input into a geographic information system GIS with interactive maps. These maps are used to identify the swelling potential at various locations of puducherry with the study of damages in the form of cracks identified. The efficiency is very high when using computer techniques. Engineering properties of an expansive soil are investigated using in situ and compacted samples. The objective of the topic is to discuss the factors influencing the swelling behaviour and the associated damage in low rise buildings. The allowable and prediction of such damages in residential buildings is presented in terms of engineering properties and associated damage. Presence of high plastic clay indicates the existence of expansion soil problems. Expansive soils all over the world cause serious problems on civil engineering structures which lead to lakhs of amount to rectify the damage problems associated in the buildings. Soil properties mapped in this study which influence the damage potential of the engineering structures are clay mineralogy, liquid limit, plastic limit and initial water content, plasticity index, dry density. Environmental factors and initial moisture content, climate, Ground water drainage conditions and vegetation and soil profile of clay soil of the study are made in the database. So knowledge of this soil characteristic to the public will be useful to choose correctly the right type of foundations and right time to progress the stages of constructions.

Abstract:Bacterial strain capable of producing extracellular blue-green pigment was isolated from soil samples. The blue-green extracellular supernatant showed antimicrobial effect against F. oxysporum and E. coli DH5α on solid culture. Minimum inhibitory concentration (MIC) for both the microorganisms were measured by the Kirby-Bauer method. The extracellular supernatant had shown more inhibitory effect on E. coli DH5α than F. oxysporum confirming better antibacterial efficiency than antifungal one. The characteristic blue colour of the chloroform extract obtained from the extracellular matrix of the bacterial culture indicates the pigment and the bacterial isolate to be pyocyanin and Pseudomonas aeruginosa respectively.

Abstract:This study aims to prove the effect of information quality and service quality on customer experience and its impact on customer trust and customer advocacy. Customer experience is used as the primary assessment between behavior before making a purchase and behavior after purchasing. This type of research is explanatory research, which uses direct surveys of airline passengers in Indonesia through an online questionnaire to obtain primary data. Then it is processed using the smartpls3 application. The results showed that information quality and service quality had a direct effect on customer experience and indirectly had an impact on customer trust and customer advocacy. Service quality has the most dominant influence on customer experience than information quality. Information quality and service quality have an indirect effect on customer advocacy through customer experience and customer trust.
