There is a lot of development in surgery and prosthetic fields. For this purpose, a lot of materials are used as implants for replacing them in place of damaged parts. These materials are called bio materials. It has been observed that one of the most important properties governing the suitability of the material to be a bio implant is ‘wear resistance’ ‘Corrosion Resistance’. This paper explains about mechanical properties on Magnesium hybrid composites for bio-medical applications.

Shielded metal gas welding techniques’ impact on the welding of AISI1040 steel have been qualitatively investigated (MIG and TIG). The experimental layout must be developed using the Taguchi approach. Arc voltage, arc current, welding speed, nozzle to work distance, and gas pressure have all been found to have an effect on weld quality. The backing plate’s thickness as well as the plate’s thickness both matter. A trial design based on an orthogonal array is used to create weldments. To determine how successfully the weldments were welded, a set of tests are performed on them. ANOVA is used to assess the suitability of the data. The computed result is used as a contribution from each parameter to obtain the optimum values for fault minimization. Weldments are examined using an angle beam test, and the outcomes are assessed using ultrasound testing (UT). The presence of faults in the tested specimens, such as LOP, ...

The main problem of the air preheater is the leakage of air on the side of the gas flue and thus lead to improper thermal performance. Thehigh ash content in Indian coal also adds to the problems associated with air tube heating. Air preheaters are designed to meet the operational requirements with consideration of the most impact parameters. heat transfer, leakage and pressure reduction. In the current work the performance of the air-conditioning heater is being tested with the help of the computational fluid dynamics (CFD)Fluent 14.0 analysis tool.

In this present investigation 304L having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity. Argon and CO 2 was employed for shielding purposes. The fusion zone is defined by a few geometrical characteristics, such as bead width, bead height, and penetration depth. A number of factors influence the configuration of the fusion zone, including gas flow rate, voltage, travel speed, and wire feed rate. Micro hardness measurements were done over the weld bead base material to better understand the Knoop micro hardness.

The acetate group confers acetyl-TAG with unique physical properties such as reduced viscosity and lower freezing point, providing advantages for use as emulsifiers, lubricants, and 'drop-in' biofuels. Previously, the synthesis of acetyl-TAG in the seeds of the oilseed crop Camelina sativa was achieved through the heterologous expression of the diacylglycerol acetyltransferase gene EaDAcT, isolated from Euonymus alatus seeds that naturally accumulate high levels of acetyl-TAG. Subsequent work identified a similar acetyltransferase, EfDAcT, in the seeds of E. fortunei, that possessed higher in vitro activity compared to EaDAcT. In this study, the seed specific expression of EfDAcT in camelina led to 20 mol% increase in acetyl-TAG levels over that of EaDAcT. Coupling EfDAcT expression with suppression of the endogenou...

They are also widely used in process applications as well as the refrigeration and air conditioning industry. The robustness and medium weighted shape of Shell and Tube heat exchangers make them well suited for high pressure operations. The aim of this study is to experiment, validate and to provide design suggestion to optimize the shell and tube heat exchanger (STHE). The heat exchanger is made of acrylic material with 2 baffles and 7 tubes made of stainless steel. Hot fluid flows inside the tube and cold fluid flows over the tube in the shell. 4 K-type thermocouples were used to read the hot and cold fluids inlet and outlet temperatures. Experiments were carried out for various combinations of hot and cold water flow rates with different hot water inlet temperatures. The flow conditions are limited to the lab size model of the experimental setup. A commercial CFD code wa...

Their superior specific strength and stiffness characteristics have made them very competitive in the aerospace industry. The primary limitation of fiber reinforced composites is fracture toughness, specifically delamination. Delamination failures are common due to the nature of composite construction. A variety of manufacturing techniques are available to make composites. Generally, all these methods employ a layered stacking of fibers in a primary plane. The interface between these layers is typically not reinforced with fibers and is the source of delamination or interlaminar fracture. Porosity and Other manufacturing related defects also introduce nucleation sites for delamination. Methods exist to evaluate and quantify inter-laminar fracture toughness, both experimentally and analytically. The material property that best represents resistance to delamination is the strain energy release rate (G C). This can be experimentally obtained and numerically predicted with some success. The primary focus of this study was to characterize and address interlaminar fracture in composites. An interlaminar fracture for mode I crack propagation was analysed for GFRP materials having 0 0 orientation of fibres. Experimental investigation of G C was done for 40%, 50% and 60% of fibre volume. Test was conducted using Double Cantilever Beam specimen. Results obtained were again correlated with Numerical analysis using VCCT method. Results of both experimental and numerical methods were in good agreement.

This paper focuses a new technique for detecting any modification in the time series profile shape caused by an impending earthquake to identify precursors as well as an image processing technique for epicenter detection. For this purpose IGS Global Navigation Satellite System (GNSS) Total Electron Content Data (TEC) are utilized from different stations across the world. From the experiment it is observed that the method may detect earthquake precursors a few hours or days prior to the main event due to ionospheric perturbations induced by initiation of earthquake process.
