Effect of Thermal Barrier Coating With Different Thickness in Piston to Enhance Temperature Distribution
Authors: Sujeet Kumar, Anurag Bagri, Vinay Kumar Yadav
Abstract
In the current work, the CAD model of pistonhas been developed by using ANSYS design modeler. The model has been simulated using ANSYS software on steady state thermal and static structural domain 15.0 workbench in order to observe various parameters effecting the temperature distribution between different thickness of thermal barrier coating. Four types of configurations of coating thickness were used i.e. 0.5, 0.7, 0.9, 1.2 mm. An optimized model of pistonhas been developed as stated configurations of coated piston. The simulations have been performed at a standard temperature that is the temperature generated during working of internal combustion engine. The simulation of the optimized model gives lower value of temperature distribution, thermal stress and deformation. The results are validated with reported existing previous work. The configuration of thickness between 0.7 to 0.9 of thermal barrier coating coated with sodium stannate material exhibits higher temperature distribution compared to titanium dioxide, zirconium and Ai - Si.

Abstract
Dengue is another infection caused by mosquitoes. It is a very common infection mainly in tropical and subtropical regions. In India, it is affected in all regions urban and rural. Dengue hemorrhagic fever is a very serious condition that has serious complications that leads to hospitalization and also death in some people especially in children. Second-time infection is dangerous but, one type of virus provides lifelong immunity. But the vaccine is available from 2015 for the age group between 9 to 45 who has previously dengue fever. According to the data by National Vector Borne Disease Control program, there is a drastic decrease in the death rate in India due to dengue fever. Carica papaya is a tropical plant, the leaves extract has medicinal and nutritional benefits and has a significant effect in Dengue fever patients in increasing platelet count. India has a strong culture of using herbs, and plant- based products in the treatment of various diseases. In the present study, thirty patients who are affected with dengue fever and platelets below 40,000 cmm, who are admitted to the different hospitals of Mumbai are selected. As per the doctor’s advice, they have consumed 30ml of Carica papaya leaf extract, evaluation study is done to find the efficacy of Carica papaya leaf extract in increment of platelets. In all the patients it is observed there is a significant increase in the platelet count from baseline to day 6. It is evident that the leaf extract has the efficacy to increase platelet count and will aid in controlling complications and hospital stay.

Abstract
Plastic waste has emerged as one of most difficult to tackle waste due to long life of plastics. Polyethylene terephthalate (PET) in one of major plastics which is used to make bottles for beverages and packaged drinking water. These bottles are mostly of single use and are needed to be disposed once used thus having a great environmental impact. On the other side concrete is a major construction material and raw material for making it are growing scarce. Finding alternative to the cement, fine aggregates and coarse aggregates for concrete is need of the situation. There have been many studies done for checking the effect of use of PET waste on mechanical strengths of concrete i.e., compressive strength, split tensile strength and flexural strength. This paper examines various literature reviews in which waste PET has been used as partial replacement in concrete. Plastics are an astounding discovery of man and have become an indispensable and inseparable part of a common man’s life. The disposing off of several existing forms of plastics in nature has always been a key matter of concern to man. Plastics are one of such products which are littering the oceans and environment. Hence there is a dreadful requirement of some solution to effectively solve this problem of disposal to reduce the environmental strain. The researchers are trying to incorporate one waste product or the other into concrete so that it can help in a dual way- decreasing the strain on environment and the effective utilization by enhancement of various mechanical properties of concrete. Research studies have made it quite clear that the PET waste has the capability to enhance various parameters of concrete which is a far better option than sending it to landfill. The research studies on PET fibres have also confirmed one more thing that these can be more effectively utilized by modifying the shape of fibres and their bonding properties.

Abstract
In the course of recent years, numerous organizations have acquired advantages from the execution of cloud solutions inside the organization. Because of the benefits like adaptability, portability, and costs saving, the quantity of cloud clients is required to develop quickly. Therefore, organizations need a safe method to authenticate its clients to guarantee the usefulness of their administrations and information put away in the cloud storages are overseen in a private climate. In the current methodologies, the client verification in cloud computing depends on the qualifications presented by the client like secret word, token and computerized authentication. Lamentably, these accreditations can frequently be taken, inadvertently uncovered or difficult to recollect. Taking into account this, we propose a biometric-based validation convention to help the client verification for the cloud climate. Our answer can be utilized as the second factor for the cloud clients to send their verification demands. In our plan, we join a few players (customer, administration specialist and specialist co-op) to work together to play out the coordinating with activity between the inquiry include vector and the biometric layout of the client. Specifically, we consider an appropriated situation where the biometric layouts are put away in the cloud storage while the client validation is performed without the spillage of any sensitive data.
