 Abstract

Labyrinth seals are used to perform sealing around the rotating Parts of various mechanical machineries. Its work is to minimize escape of fluid essentially gases from high pressure area to low pressure area this is process by building of series of labyrinth teeth which are arranged to provide a close clearance gap between the stator and rotor components of the machine, this may cause a pressure drop occurs across each gap. The main aim of this study is to discuss the Optimization of Circular-Grooved Square Cavity Labyrinth Seal and CFD Analysis Based on ANN Modelling. The methodology for developing two semi-theoretical-semi-experimental formulae and linking them with the ANN technique for obtaining the optimal CSLS is described in this paper. It is concluded that the CFD analyses of the optimal seals confirmed the improvements caused by the cavity shape and captured performance parameter trends. The Pr values of 1.6 are found in the best circular-grooved square and triangular cavity labyrinth seals.

 Abstract

The Kole wetland, one of the largest, highly productive and one of the rice granaries of Kerala, has been declared in Ramsar convention for protection. Ponnani Kole, the study area, is situated in south-west of Malappuram and north-west of Thrissur districts, is the northern most extension of the Vembanad Kole Ramsar site. However, to the best of our knowledge, no solemn attempts were made to study the ecological impacts of these Kole wetlands especially emphasising biodiversity, physico chemical characters and human dependence. The present study is based on field survey and laboratory analysis of selected species. The study reveals the significant variation in stress physiology among plants grown in the area of high ecosystem diversity. It is also noticed, a massive destruction of the vegetation in the Koleland are very high due to natural and anthropogenic activities. Soil erosion also very high in Koleland and this leads to declination of vegetation as well. Study elucidated the physiological changes and related tolerance mechanism that occur in three plants according to the ecological variations during different seasons.

 Abstract

Health is a defining concern in public policy discussions in every mature society, often mandating the deployment of enormous populations. Inequalities in health, access to health care, and the quality/cost of treatment contribute to a nation's economic well-being, given a current biological understanding of health and illness. Health insurance covers all clinical quality, not only medical treatment. There cannot be a sole emphasis on publicly financed health care but also on incentives and disincentives for self-care and treatment funded by private individuals to recover from sickness. In countries such as India, where private out-of-pocket expenditure dominates health care expenses, the resulting repercussions are sure to be regressive. At its core, the healthcare system is viewed as general welfare. Consequently, its demand and supply cannot be determined by the market's invisible hand. Vulnerable people should be prioritized, such as children, women, and the elderly. The disparity in health status among rural and urban regions and across states is well established. As one age, inequalities between urban and rural areas grow more prominent, with a five age gap becoming more evident. Apart from the battle for survival, rural villages are infamous for their lack of access to almost every community service. The prevalent practice of female feticide is expected to exacerbate the disparities among rural and urban children. This paper discusses the present Indian health system. The research will concentrate on the health system and its prospects, including its problems and concerns.

 Abstract

The study was conducted to develop and evaluate different evaporation estimation models considering importance and difficulty in measurement of evaporation.Models were developed for predicting pan and pond evaporation on multiple linear regression, and energy balance method. For pan evaporation, model developed by energy balance method gave results with highest coefficient of determination (R2 = 0.9473), lowest root mean square error (1.1403 mmday-1) with closer association between estimated and observed evaporation. For pond evaporation the model developed by stepwise multiple linear regression analysis gave results with highest coefficient of determination (R2 = 0.9638), lowest root mean square error (0.7377 mmday-1) with closer association between estimated and observed evaporation.

 Abstract

Users have control over their health and well-being thanks to AI. AI also enhances the ability of healthcare professionals to recognize the recurring patterns and needs of the patients they look after, allowing them to provide better feedback, guidance, and support for preserving health. In this paper we understand hoe the reliability model works for AI techniques used in excretory problem in medical field. All are important; if AI techniques and equipment are used to cure excretory diseases then reliability model gives the reliability of those particular AI technique in particular excretory diseases.
