 Abstract

Tubesheet of the Shell and tube heat exchangers designed as per part UHX of ASME Pressure vessels codes. In the past, the tubesheet was designed by this analytical method irrespective of tube layout. However this analytical method does not holds good for NTIW type Tube layout. This research work presents design and analysis of NTIW tubesheet shell and tube type heat exchanger using ASME code formula, TEMA Standards and FEA analysis. After completion of design calculation and stress results by analysis, the stresses at various location on tubesheet i.e. at perforated and non-perforated region has been evaluated. In this research, design has been carried out in PV Elite 2017 software. Design data and other important things were provided by the external guide as per requirement. Design has been carried out as per ASME Section viii, Div.1, UHX-13 and according to TEMA Standard. After completion of design, analytical calculation of NTIW tubesheet was performed in PV Elite software and then after the analytical design report for NTIW tubesheet was generated. After design and analytical calculation, FEA analysis has been carried out in Ansys. For analysis, to overcome the higher hardware requirements of computer as the numbers of tubes are 6992, the criteria of equivalent perforated material given in ASME Section VIII, Div.2, part 5, Annexure 5E utilized for analysis. So in this research we have compare different stresses at different location of perforated and non-perforated regions using FEA analysis. So after studying the the results, it is observed that the stress induced in analysis are higher and deformation is also higher. So it can be concluded from the comparison of the results that the analytical method does not provide the reliable design of tubesheet as per UHX. Hence, the tubesheet thickness can be increased and the stress for same design condition shall be evaluated.

 Abstract

Virtual reality is an experience that puts the user into a simulated environment meant to reproduce the feelings we experience in our real life. It uses computer technology to place the user inside this reality instead of having him to look at a screen. It tries to simulate as many of our senses as possible such as sound, smell, vision, touch etc. to immerse us into the virtual world. They are used in entertainment industries to put the users in the media they are using, in the military to provide them with the real life situations the soldiers may face or in the learning and education department to provide them with deep learning of their courses.

 Abstract

Tourism is one of the drivers of the economic progress of the community and increases government income. Through tourism, it can create jobs and thus reduce unemployment. However, if tourism is not managed properly, it will not increase or boost the economy. This is the case in small Islands in Guinea-Bissau. Guinea-Bissau has very beautiful islands, blue sea, very white sand, birds, sea hippos and a very beautiful culture. However, this is not managed and even there is no promotion or even no assistance from the tourism office. So that it results in very small community income and very low tourism office income.

 Abstract

This paper intends to analyse the treatment of womanhood in T. D. Ramakrishnan's Sugandhi Enna Andal Devanayaki and Mani Ratnam's Kannathil Muthamittal. Women are adversely affected in power struggles. Irrespective of age and status, women are abused in the patriarchal society. The mental and physical agony experienced by the female characters finds expression through the two medium; fiction and film. The conventional and unconventional womanhood and motherhood are addressed in a traumatic manner that highlights the plight of women in the Sri Lankan Civil War. Womanhood portrayed in the two narratives exemplify the role of women in nation building. The choices made by the female characters ultimately define their inclination towards motherhood or nationalism. This study is an attempt to showcase the different perspectives of womanhood and their bruised self, rather than confining them to typical stereotypes.

How it is formed :- Serum Vitamin E level in the body totally depends on the liver. Liver which function is to take up the nutrient after various forms are absorbed from the small intestine. After the process of metabolism, the liver rescretes only alpha tocopherol and other forms of vitamin E are excreted. We know that, free radicles are the molecules containing an unshared electron. Antioxidant in the form of Vitamin E protect the cells from the damaging effects of free redicles. Free radicals are responsible for the developing cardiovascular disease and malignancy also. Immunity is also produce by vitamin E, Apha tocopherol of inhabits the activity of protein kinase C, which is an enzgme involved in cell proliferation and differentiation in smooth muscle cells, platelets and monocites. Vitamin E also replete endothelial cells lining the interior surface of blood vessels are better able to resist blood cell components adhering to this surface. Vitamin E also increases the expression of two enzymes that the arachidonic acid metabolism, therapy increasing the release of prostocyclin from the endothelium which in turn, dilatos blood vessels and inhibits platelet aggregation.
