Fiber-reinforced polymeric composites are used widely due to their unique properties of light weight, stiffness and high strength weight ratio. During processing and servicing, the composite materials undergoes delamination, and petalling. Computational model was constructed for finite element modeling to reflect material purpose under impact load and relevant material properties were taken. In...

Many companies in India manufacture solar water heaters but these are not becoming popular in the domestic sector because of their high cost. The Ministry of Non-Conventional Energy Sources (MNES), New Delhi is recommending flat-plate collectors with copper (Cu) risers, headers and plate. Therefore, their cost is high. Long term studies have been carried out at the Central Arid Zone Research In...

This paper presents the first study of the UV imaging of spots on thin-layer chromatographic plates whilst still wet with solvent. Imaging of spots of benzophenone during and after development was carried out using a charge-coupled device camera. Limits of detection were found to be 5 ng on a wetted plate and 3 ng for a dry plate and the relationship between peak area and sample loading was fou...

Now a days, significant amount of aluminium alloy are being used to fabricate components such as engine blocks, cylinder heads, suspension control arms, wheels and pistons. In response to consumer demands for the increase in performance, the use of aluminium has grown dramatically in the recent years. So in order to produce a sound LM6 (Al-12%Si) Aluminium alloy casting, a new approach is made ...

The present work focuses on a numerical investigation of nanofilms’ (water/copper and water/aluminium) evaporation inside heat exchanger by mixed convection flowing down one channel plate. was composed two parallel vertical plates. wetted plate heated while the other maintained isothermal dry. impact dispersion different types nanoparticles in liquid film their volume fraction mass exchange pro...

The radiolucent surface plate of the C-arm image intensifier is often used as an operating table, particularly in surgery on the hand. The advantages include easier positioning and clearer quality of the image. We wish to draw attention to the dangers of this practice. Examination of our image intensifier has shown three penetrating holes and a number of scratch marks on the surface plate which...

Modern field fortification systems are very large and cause a logistical burden during setup, thus setting the requirement for their modification. A simulation study was conducted to correlation between compaction of sand energy absorbed by it when impacted solid steel projectile at 850 m/s. Furthermore, sandbag modified addition plates in system observe change penetration absorption behaviour ...

pant h & tripathi s. 2011. Fumigation of wood with aluminium phosphide for protection against fungi. The search for alternatives to the environmentally harmful fumigant methyl bromide has led to the evaluation of phosphine as preshipment and in-transit treatments for logs and sawn timber. The biological activity of aluminium phosphide against wood decaying fungi was determined using agar plate ...
