Experimental analysis of free convective heat transfer through micro channels with different configuration
The microchannel heat sinks play a very important role in the functioning of the microelectronic components. In this paper, the focus is on the convective heat transfer performance of the microchannels with different diameters and configurations. The heat transfer performance is a function of surface area available for the heat transfer and the heat transfer coefficient of the heat carrying medium. It is highly desirable to understand the fluid flow and the heat transfer characteristics of a buoyancy-induced micro pump and micro heat exchanger in microfluidic and thermal systems. In this study, we experimentally investigate the fully developed natural convection in an open-ended vertical cylindrical microchannel with asymmetric wall temperature distributions. The experiments were conducted in both horizontal and vertical orientations. Results reveal that in most of the natural convection situations, the volume flow rate at the micro scale is higher than that at the macro scale. It is, therefore, concluded that the temperature jump condition induced by the effects of rarefaction and fluid-wall interaction plays an important role in slip-flow natural convection and heat transfer rates are higher than vertical configurations the evaluated experimental results are compared with available literature and graphically noted.

Modified genetic algorithm for automated facility layout design
The placement of facilities is a fundamental task in many industries, and the facility layout problem is frequently encountered. This paper describes the implementation of a modified genetic algorithm for solving the facility layout problem by minimizing the total material handling the cost. An isomer-based elitism is applied and the performance of the proposed algorithm is compared with previous results in the literature. An extended method for measuring the efficiency of the algorithm is proposed. The results suggest that the efficiency of the proposed methodology is competitive with prior work and that isomer-based elitism should be reviewed for application in a wider range of problems.

A review on digitalization of SHG with mobile usage in India
Microfinance program promoted by the government of India through ‘The National Bank for Agriculture and Rural Development’ (NABARD) has impacted thousands of villages throughout India for the last twenty years. According to NABARD, 11crore household across India with over 87 lakh Self Help Groups created deposits over Rs. 195 billion. India has a platform of over billion mobile users and a half billion internet users and financial transactions, especially through United Payment Interface by the government of India, make the financial transaction process easy and transparent through banks for customers. E-Shakti launched by NABARD in 2015 has digitalizing information of SHG across India. World bank has seen online bookkeeping of SHG raising over a million transactions every week across lakhs of house households even in a rural area. This paper presents the significance of paradigm shift of digitalization of SHG with mobile.

CFD analysis of combustion chamber of SI engine during suction stroke
This work is suitable for the IC engine design and analysis industry in understanding the various performance characteristics of the flat and dome head piston. The design of the piston and chamber has a vital role in the optimized performance of an engine. There are lots of studies undergone about the new piston geometries and designs to achieve the optimized results. Studies about the piston and combustion process include both the structural and thermal analysis because both pressure and temperature are the two important properties which affect the performance of the piston and chamber. This work designs a new model of flat and dome piston for an assumed optimized output of the existing engine and chamber. This work will be helpful for the new inventions in engine development. In this work piston and chamber are modelled in CATIA v5 software and these models are imported into ANSYS software and analysis is employed. Structural and thermal analysis of the piston and air flow analysis of the chamber is employed for both flat and domed piston.

Synthesis of FeOOH by electrochemical deposition techniques
We are conducting FeOOH platelets were successfully synthesized on ITO substrate by an electrochemical deposition method also conducting a multi-disciplinary research work that involves the development of nanostructured thin films of semiconductors for different applications. Nanotechnology is widely considered to constitute the basis of the next technological revolution, following on from the first Industrial Revolution, which began around 1750 with the introduction of the steam engine and steelmaking. Nanotechnology is defined as the design, characterization, production, and application of materials, devices, and systems by controlling shape and size of the nanoscale. The nanoscale itself is at present considered to cover the range from 1 to 100 nm. All samples prepared in thin film forms and the characterization revealed their nanostructure. The major exploitation of thin films has been in microelectronics, there are numerous and growing applications in communications, optical electronics, coatings of all kinds, and in energy generation. A great many sophisticated analytical instruments and techniques, largely developed to characterize thin films, have already become indispensable in virtually every scientific endeavor irrespective of discipline. Among all these techniques, electrodeposition is the most suitable technique for nanostructured thin films from aqueous solution served as samples under investigation. The electrodeposition of metallic layers from aqueous solution is based on the discharge of metal ions present in the electrolyte at a cathodic surface (the substrate or component.) The metal ions accept an electron from the electrically conducting material at the solid- electrolyte interface and then deposit as metal atoms onto the surface. The electrons necessary for this to occur are either supplied from an externally applied potential source or are surrendered by a reducing agent present in solution (electroless reduction). The metal ions themselves derive either from metal salts added to the solution, or by the anodic dissolution of the so-called sacrificial anodes, made of the same metal that is to be deposited at the cathode.

A review on mouth dissolving tablets of Glimepiride
Oral route is considered as the most common and preferred technique for drug administration because it is considered as the easiest and simplest method. The route provides simplicity of drug administration in a handy way and individuals tend to be more knowledgeable about this particular route. The latest developments in Novel Drug Delivery System (NDDS) seeks for improving effectiveness and molecules security that were used previously by preparing a suitable dosage forms for administration. Now a days the problems such as dysphagia are faced by the conventional dosage forms like capsules and tablets, which results in ineffective therapy because of high incidence of non-compliance. Mouth dissolving tablets (MDTs) were developed to prevent above issues in conventional dosage forms. These MDTs have easy administration, dose uniformity, and good hardness as well as are the first preference for the travelling, geriatric, and pediatric patients. This paper provides a review for MDT because of its wide significance, as well as such drug delivery system may help for better compliance of patient along with ultimate clinical output.
