The average life span of knee prosthesis used in Total Knee Replacement (TKR) is approximately 10 to 15 years. Literature indicates that the reasons for implant failures include wear, infection, instability, and stiffness. However, the majority of failures are due to wear and tear of the prosthesis. The most common biopolymer used in TKR  is Ultra High Molecular Weight Polyethylene (UHMWPE). Pr...

A detailed experimental evaluation of earcons was carried out to see whether they are an effective means of communicating information in sound. An initial experiment showed that earcons were better than unstructured bursts of sound and that musical timbres were more effective than simple tones. Musicians were shown to be no better than non-musicians when using musical timbres. A second experime...

The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...

Aerosol solvent extraction system (ASES) was used to prepare micro-particle of acetaminophen by supercritical carbon dioxide as an anti-solvent. Experiment was carried out at various temperatures, pressures, solvents and investigated the effects of these parameters on particle size, size distribution and morphology by SEM and laser diffraction particle size analyzer. It seems that the choice of...

the results of researches in the field of the using x-ray in all over the world have been successful. the main subject which needs more investigation and have been allocated part of the researches in most of the atomic research institutes, is the research about possible harms of irradiated food for human beings, base on the researches, using irradiation for inhibition of sprouting and preservat...

This paper reports an experiment conducted to assess the contribution of a computer system in the milking parlor to the detection of mastitis and estrous (udder infection and the time to inseminate the cow). The experiment was carried out in a herd of 700 cows in Israel. It was found that the computer system contributed markedly to the cows' productivity and profitability. (

This research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1,  0.2 and  0.3 mg/Kg) on reproductive traits of rooster. Semen was collected using abdominal massage and samples were mixed together. Sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. This experiment was carried out based on...
