A novel tetra-peptide insertion was identified in Gag-p6 ALIX-binding region, which appeared in protease inhibitor failure Indian HIV-1C sequences (odds ratio 17.1, P < 0.001) but was naturally present in half of untreated Ethiopian HIV-1C sequences. The insertion is predicted to restore ALIX-mediated virus release pathway, which is lacking in HIV-1C. The clinical importance of the insertion needs to be evaluated in HIV-1C dominating regions wherein the use of protease inhibitor drugs are being scaled up.

To review the design of working research model associated with maximum utilization of waste heat via installation of water chamber in between compressor and condenser. Vapour compression refrigeration system is most typically and domestic and as well large-scale approach to generating refrigerating effect. On the process, it rejects large amount of heat which is actually dumped to environment as waste products. The rejected waste heat could possibly be utilized to run any low-grade heat required refrigerating system. The recovered hot water could be put to use for home purpose like heating water, bathing, washing in addition to large scale industrial purpose like fabricating, processing, diluting, incorporating water into product or perhaps for sterilization necessities. This paper proposes and attain optimum utilization of waste heat recovery from VCR system that has nominal constructional, renovation and operating cost, substantially useful for domestic intent.

In the present work of CFD analysis of NACA 2313 and NACA 7322 is to find out the efficient airfoil design out of the two airfoils. The coordinates of airfoils were generated by using NACA 4 digit airfoil generator. Results are computed by ANSYS FLUENT 14.5. Analysis is based on various parameters like Coefficient of lift, Coefficient of drag, coefficient of Pressure, and Pressure around the airfoil. The comparison is carried out at 6° and 10° of Angle of attack. An airfoil which has high Coefficient of lift/Coefficient of drag ratio is considered to be better than the other. In this case, based on simulation results it is concluded that the airfoil NACA 2313 is superior to NACA7322.

On the face upcoming energy crises in the world it becomes necessary to focus the alternative of conventional fuel. To overcome this extra energy due to which this crisis persist and to investigate these substitutes of conventional fuels it is also necessary to examine them in a well manner so that they can fulfill the requirement of energy in an economic way. This paper is focused to analysis the thermal performance use such resource that is biodiesel derived from waste cooking oil (WCO) and its blend by setting up experimental setup in compression ignition engine. In this paper the thermal analysis of exhaust gas of an engine has been carried out using WCO Biodiesel blend as a fuel. This is carried out by measuring the temperature of exhaust gas with respect to different values of power output along with the fuel consumption. The Biodiesel is blended with pure diesel in different proportions as B5, B10, B20, B40, B60, B80 and B100 and same is used in CI engine in varying load cond...

In the COVID-19 pandemic, control of airborne virus transmission is exceptionally challenging as it is attached to suspended particles in the air and stays for an extended time. Air contaminated with airborne viruses holds a substantial risk for household transmission. In this study, a novel thermal treatment system is modeled based on porous heating for the decontamination of airborne SARS-Cov-2. The model includes an air heating domain, insulated chamber, buffer tank and heat exchanger. The airborne SARS-Cov-2 is decontaminated when passing through a porous heat pipe and the insulated chamber for an anticipated dwelling period of more than 5 min at 105°C and further stored in a buffer tank for natural cooling. The obligatory decontaminated air is allowed in the residential space under ambient conditions passing through a heat exchanger. The numerical investigation of the porous pipe model at different L/D ratios with altered porosities aims to establish the best-performing porous domain. Besides this, the buffer tank is intended to maintain buffer storage of the treated air and significant natural cooling before passing to the heat exchanger. A solar PV module is proposed to meet the prerequisite energy requirements of the equipped devices.

Room air conditioners are mostly used in a particular room in public buildings. RACs used for both heating as well as cooling purposes. RACs are available in different variants like 1 ton, 2 ton. In this paper, we will determine and find out exact or near about the temperature required for the selected room in which we put AC. This is important for some reasons. Undersized unit AC-This will not cool the room in more summer or hot weather season. Oversized unit AC-This will affect the body comfort by more cooling and also high money. So, by using calculation of room we will able to find out how much we have to give cooling or heating the room. For this we will save energy as well as money and the wastage of heat in the atmosphere.

Plate heat exchanger PHE) is type of heat exchanger in which heat transfer takes place between fluids through separating wall. The geometry of PHE is one of the most important factors of rate of heat transfer and pressure drop .corrugation of plate inhances heat transfer due to increasing the turbulence in flow. Now a day PHE is being used widely in heating application, food industry, chemical industry, refrigeration industry, marine application and fresh water generation system from sea water. The objective of this paper is to review the effect of chevron angles and numerical investigation of dimensionless numbers. Further we shall design the PHE by using the solid work design software with chevron angles 45•, 61•, 63•, and 65• at constant dimensions. The rate of heat transfer coefficient, pressure drop dimensionless numbers like Nusselt, Prandtl and Reynolds numbers will be evaluated by using the Ansys simulation software.

Research Scholar SRCEM Banmore Gwalior M.P Assistant Professor SRCEM Banmore Gwalior (M.P.) ABSTRACT-The Airfoil NACA 4415 of aerodynamics are mainly used as a wind turbine blades. So the selection of suitable angle of attack for the projected airfoil section involves in this. So the reason of this study is to investigate the behavior of NACA 4415 air foil at different operating condition. In this research CFD analysis has been done over NACA 4415 has been used in fluent 6.3.26. The CFD analysis has been done for angle of attack 12 0 , 14 0 , 16 0 and 18 0 at Reynolds Numbers 1000000 and 1500000. It was found as the angle of attack enhances, the coefficient of lift also enhances, but after 16 0 coefficient of lift started to reduces due to adverse pressure gradient at the trailing edge.

In this work an indirect evaporative cooling system is applied in a dessert cooler instead of direct evaporative cooling system. This work is carried out to cool the air without letting air come in direct contact with coolant (water) and it was done to contain the humidity at low level inside the room which is to be cooled. To achieve this object a heat exchanger was introduced where indirect evaporative cooling takes place and to enhance air cooling a cooling tower and forced air draught on surface of heat exchanger was also added. This work had shown efficiency up to 72-89% and was able to bring the room temperature from 35℃ to 30℃.
