background and objective: methicillin resistance in staphylococcus aureus is an increasingly important clinical problem. a chromosomal gene, meca, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in staphylococcus aureus. we evaluated the validity of disk diffusion test by using oxacillin, methicillin and cefoxitin disks with consideration of the pres...

conclusions altogether, ozone had significant positive effects on patients with disk herniation unresponsive to other conservative and minimally invasive treatments. background disk herniation (dh) is one of the most common disk lesions, inducing low back pain (lbp). various therapeutic options have been proposed for treatment of disk herniation (dh). intradiscal injection of ozone has been sug...

in this paper, finite element elastic contact analysis of a functionally graded (fg) hollow brake disk in contact with pad, subjected to rotation, contact pressure and frictional heat is presented. the material properties vary through the thickness according to a power-law characterised by a grading index, n. the material property is purely steel at the core part and gradually moves and approac...

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...
