Diabetic Retinopathy is a microvascular impairment which leads to blindness in the developed and developing countries. The DR progress from non - proliferative diabetic retinopathy to proliferative diabetic retinopathy were new blood vessels are formed which is called as microaneurysms. The onset of diabetic retinopathy depends on the period of the diabetes mellitus. The uncontrolled blood glycaemic level results in diabetic retinopathy. The single nucleotide polymorphism or genetic variants may be responsible for the genesis of diabetic retinopathy. This review paper mainly focuses on the diabetic retinopathy, its pathophysiology and its genetics which includes VEGF, AGEs, ALR, Epo and eNOS. The ubiquitin proteasome pathway also plays a major role in DR as the expression of Proteins of the UPS system are high in retina and any variation in the gene causes the DR. The SNPs that are associated with diabetic retinopathy in different cohort is also discussed in this review. © 2020 Elsevier Ltd. All rights reserved.

The objective of the work is to provide the outcomes of Scanning Electron Microscope (SEM) and X-ray diffraction (XRD) tests and their investigations on natural, lime-treated clay and lignosulphonate-treated clay to estimate the percentage of bonding compounds after soil stabilization. XRD tests were performed on natural soil and soil-treated mixtures of 3% lignosulphonate by mass. These mixes were tested at a distinct period of curing of 28 days and tested as the sample before the addition of lignosulphonate and after treatment of soil with lignosulphonate. Strength Improvement has been observed due to the increase in Quartz mineral which is SiO2 in nature. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

In this paper a unique approach towards decision making process and better quality care inPati healthcare applications is developed by using the Machine Learning (ML) concepts as an alternative mode for identifying the characteristics and patient satisfaction (PS) in the proposed healthcare system. Extracting the information from raw data using some algorithmic approach is known as Data mining. In this a ML approach is used in determining the patient satisfaction in health care sector. Applied regression models to determine the patient satisfaction and also correlation methods is identified as an important attribute to be considered in determining the better quality of health care application models. The data set is taken based on the opinion on three types of data such as a) patient opinion towards hospital care b) nurse opinion towards workplace and c) Administrative aspects of healthcare. Our findings revealed high accuracy in Regression (88%), that helps in concluding by considering the administrative and workplace attributes related to patient satisfaction. The results are validated using traditional statistical methods like binomial correlation and linear regression. © 2019 IEEE.

作者： Anbuchezhiyan, G. Saravanan, R. Pugazhenthi, R. Rathinam, V. Nagireddy, Madhavi Saveetha University Tamil Nadu Chennai Pin Code - 602105 India Department of Mechanical Engineering Vels Institute of Science Technology & Advanced Studies Chennai 600117 India Department of Automobile Engineering VNRVJIET Hyderabad 500043 India Department of Aeronautical Engineering MLR Institute of Technology Telangana Hyderabad 500043 India

Metal cutting, in general, produces heat, which has an impact on the machining quality of the final job. The surface quality of the shaft is a major factor in fatigue stress shaft failures. Coconut oil or leftover coconut oil from Kerala chips was utilized here. shop The cutting zone temperature response is utilized to optimize the metal removal process's parameters. The cutting speed was changed from 40 to 190 m/min, the tool feed rate was varied from 0.05 to 0.20 mm/rev, and the CVD coated tool was employed with four different nose radius 0.3 mm, 0.6 mm, 0.9 mm, and 1.2 mm, and an L16 orthogonal array was used to generate the minimal experimental combinations. The results were compared to current dry machining procedures. According to the results of the experimental investigation, the proposed Alumina Nanoparticles enriched waste coconut oil based wet machining method reduces the Cutting zone temperature by 27.36 percent on average and ensures that the results do not violate the statistical assumption, it can be recommended for processing SAE 1045 material for shaft manufacturing. © 2022

Giri, Jayant Department of Mechanical Engineering Vels Institute of Science Technology & ampAdvanced Studies Tamil Nadu Chennai India Department of Mechanical Engineering Saveetha School of engineering SIMATS Tamil Nadu Chennai India Department of Mechanical Engineering Yeshwantrao chavan College of Engineering Maharashtra Nagpur India

A research endeavor is currently underway to examine the experimental analysis and development of a fuzzy model aimed at predicting the Coefficient of Performance (COP) and Mass Flow Rate within the parameters of a refrigeration process utilizing a novel refrigerant blend with nano additive materials was used. Through the application of Fuzzy logic methodology, the inquiry has pinpointed the process parameters that exhibit the most advantageous outcomes in attaining an elevated COP, alongside diminished values for compressor discharge temperature, compressor power, and mass flow rates. The investigation delves into the potential utilization of a blend comprising R152a, R290, R600, and R600a with nano particle of Al2O3. Validation of the projected outcomes was carried out through confirmation tests, which have deemed the results to align precisely with the anticipated values. The principal objective of this empirical investigation is to evaluate the operational efficacy of a residential window air conditioning unit when contemplating the substitution of R-22 with a blend of R152a, R290, R600, and R600a with nano particle of Al2O3. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

This manuscript presents the outcome of an experimental investigation conceded out to optimize the mix proportions of the concrete by the Taguchi method of parameter design. The concrete mix design is done by the L9 orthogonal array that is 34. When a new material is used in the concrete all the mix variables are taken into account so that it may cost so much, it means more need for money, material, personnel and time. In order to reduce the number of mix combination in concrete, the Taguchi method is used. In this project the cement sand and aggregate are partially replaced by cement as fly ash, river sand as M-sand and the compression values are taken and the value is compared with the conventional concrete special concrete compression value is compared with the conventional concrete and S/N value is taken from the compression value and the comparison of the values are done. In order to attain good strength and to avoid cracks, sisal fiber is added in the concrete with a percentage of (1, 1.5, and 2). © Published under licence by IOP Publishing Ltd.
