Fluid-structure interaction (FSI) was used to determine the structural mechanical characteristics of full tubular and axial-flow pumps. The results showed that as flow rate increases, total deformation equivalent stress are significantly reduced. max (MTD) (MES) pump impeller occur on outer edge blade. There two concentrations in impeller, one which is located outlet area rim, other hub. Howeve...

Certain species of Hermetia illucens, also known as the Black Soldier Fly(BSF), were found in a compost plant in Roorkee located in Northern India. Its larvae arevoracious eaters of organic waste, hence can play an ecologically-important role in solidwaste management. Morphological analysis of various stages of BSF life cycle by SEMshowed that its body along with its wings is densely covered wi...

In this research the biodegradability of 2,6-pyridine dicarboxylic acid (PDA) was evaluated. This compound has been used as a chelating agent for extraction of metal ions from contaminated soils. Initial experiments indicated that PDA was not biodegraded by unacclimated mixed cultures to any degree. However, acclimated mixed cultures degraded more than 80% of this compound within 12 h under di€...

BACKGROUND Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. METHODS With a numerical musculoskeletal shoulder model, we analysed and compared three values of thickness of a typical all-polyethylene glenoid compo...

This study was to develop a radiation sterilized polypropylene/ethylene-propylene diene monomer (PP/EPDM) binary blends using melt blending and the mechanical properties of were studied. The PP/EPDM prepared in ratios 80:20, 60:40, 50:50, 40:60 20:80. then compressed for 12 minutes Hot Cold Press machine cut into 1mm, 3mm 6mm thickness tensile test, impact hardness test Fourier Transform Infrar...

Axisymmetric vibration of an infinite Pyrocomposite circular hollow cylinder made of inner and outer pyroelectric layer of 6mm-class bonded together by a Linear Elastic Material with Voids (LEMV) layer is studied. The exact frequency equation is obtained for the traction free surfaces with continuity condition at the interfaces. Numerical results in the form of data and dispersion curves for th...

The in vitro construction of tissue-engineered small diameter (<6mm) blood vessels with sufficient strength and mechanical compliance has evaded researchers. We hypothesize that the high spatial organization of the medial layer of vascular smooth muscle cells (VSMCs) and their surrounding matrix provides high burst strength, compliance, and stability. We investigated the effect of microfabricat...

A modification has been done in the normal injection hole of 35◦, by injecting the cold fluid at different angles(compound angle) in lateral direction, providing a significant change in the shape of holes which later we found in our numerical investigation giving good quality of effectiveness in cooling. Different L/D ratios are also studied for each compound angle. The numerical simulation is ...

The spine rod in the spinal fixation system should be tough enough to support the dynamic force and flexible also for flexible movement. 5.5 mm ~ 6 mm diameter spine rods made of Ti-6Al-4V ELI are common products. Two possibilities are studied. The one is that while keeping the flexibility unchanged (using 6mm diameter), how much the fatigue strength can be increased. The other is while the fle...
