 Abstract

Friction welding method is one of the most simple, economical and highly productive method in joining dissimilar materials. It is widely used in the automotive, medical and aerospace industrial applications. The purpose of this present work was to assess the development of solid state juncture of dissimilar materials of H30 aluminum and BS970 mild steel. The joints were obtained by Friction Welding (FW) process, which combines the heat generated from friction between two surfaces. The results were analysed by means of tensile, Rockwell hardness test and metallographic tests. Solid state welding processes are characterized by the absence of melting and the formation of narrow heat affected zone (HAZ). The metallurgical properties are usually excellent and most of the processes can be mechanized or automated to be used as high production rate processes.The FW proves to be a great method for obtaining junctures between dissimilar materials which is not possible by fusion welding process.

 Abstract

This research is literally conducted to get out the ways to improve the shopping experiences of the consumers which involve both online consumers as well as traditional consumers. While conducting the current research, 200 respondents are asked to provide their expectations in the form of ranks as per their priorities. This survey is basically an Exploratory cum Descriptive in nature and purposive sampling is done for the research. This study focuses on the suggestions or recommendations of the consumers who are having different educational qualifications. The study found the key points of both of the shopping modes on which the sellers must work on to enhance their sale volume and convenience of the consumers as well.

Abstract: Atherosclerosis is the hardening of the arteries due to plaque formation. Oxidative stress and inflammation are involved in the initiation and propagation of atherosclerosis, mainly through oxidative modification of low density lipoprotein. Reactive oxygen or nitrogen species are released by NAD(P)H oxidase, nitric oxide synthase, xanthine oxidase, lypoxygenase or myeloperoxidase. Body has antioxidants defense system (enzymatic and non enzymatic) for the prevention of accumulation of free radicals. Imbalance between oxidants and antioxidants results in oxidative modification in the arterial wall leading to atherosclerosis. This review focuses on the participation of reactive oxygen species (ROS), reactive nitrogen species (RNS) and inflammation in atherosclerosis.

 Abstract

Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compatibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper presents an experimental procedure for the design of self- compacting concrete mixes. The test results for acceptance characteristics of self-compacting concrete such as slump flow, V-funnel and L-Box are presented. Further, compressive strength at the ages of 28, 56, and 90 days was also determined and results are included here.

 Abstract

The Present study was aimed to estimate and investigate some physico-chemical parameters of Wular Lake of Kashmir, India. During the present study six water samples from four accessible areas of Wular Lake were collected and analyzed for the physicochemical properties. Analysis showed a great variation in water quality among the different basins. The incoming flow channel i.e., river Jhelum and the entire catchment are having deteriorated water qualities and possible reason for this could be the increasing eutrophication resulting from agricultural practices in the nearby catchment area or tourism activity.

 Abstract

One of the challenging problems in the steel rolling industry is the distribution of the heat flux across the geometry of the rolled plate under the cooling effect of water jet. Thus, the present work focuses on the heat transfer phenomenon of the steel rolled plate. The results obtained by the simulation studies indicate that wherein the nozzle of the jet is inclined at an angle more heat flux can be generated but the variation of the microstructure is not uniform across the width due to the impingement angle. Thus, maximum turbulence is observed at 450 jet angle. The results also indicated that the heat transfer coefficients are nonlinear functions of surface temperature. At the stagnation point, the surface temperature and heat transfer coefficient are not effected by the temperature of the cooling medium i.e., impingement of jet of water.

 Abstract

With the instigation of Ad-blocking, online publishers seeking the standpoint of revenue blockage, since they rely on digital advertisements for revenues, but Ad- blocking prevents the ads, adopting sponsored content and native advertising which support internet content. Ad blockers could also push up the price of anything subsidized by advertising. For example, Fandango.com imposes a service charge on the sale of movie tickets through its site but also carries advertising in order to supplement revenue. If the site is no longer able to monetize its ad space, it would likely raise ticket prices on consumers to make up for the lost profit. This can apply to thousands of businesses across the Internet.
