I have no doubt that in this country the Heberden Society was a much-needed stimulus to the development ofa group of professional rheumatologists, for whom the Society provided self-respect at a time when ...

Based on the hypothesis that soil properties and productivity components should be affected by different tillage methods, field laboratory experiments were conducted to study effects of zero (ZT), one pass disc plough (P), plus harrow (PH) two passes (PHH) distribution bulk density, available water capacity, pH, organic matter, phosphorus, iron oxide aluminium at depths, their productivity. The...

background aeromonas hydrophila cause one of the most important diseases in fishes and lead to economic losses, and may be contaminated human beings. objectives the current research aimed to investigate the anti-bacterial activity shown by the extracts prepared from different parts of olea europea, myrtus communis, thymus vulgaris, rosmarinuis officinalis, and achillea falcata that grow in syri...

Perforated discs have many applications in different parts of industry. By making such disks of functionally graded materials, more capabilities can be obtained from them. Vibration analysis of these kinds of disks can help us make them more efficient. In this paper, modeling and evaluation of disk vibration of functionally graded materials with regard to thickness were carried out using Abaqus...

The Border Air Quality and Meteorology Study (BAQS-Met) was an intensive, collaborative field campaign during the summer of 2007 that investigated the effects of transboundary pollution, local pollution, and local meteorology on air quality in southwestern Ontario. This analysis focuses on the measurements of the inorganic constituents of particulate matter with diameter of less than 1 μm (PM1)...
