M. Kalantar and G. Fantozzi,

Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...

Background and purpose: Methicillin-resistant Staphylococcus. aureus (MRSA) is specific strain of S.aureus that is a major cause of nosocomial infection. Nowadays, Vancomycin is the first-line treatment of severe MRSA infections. However, resistance to Vancomycin is reported in the form of Vancomycin-resistant Staphylococcus aureus (VRSA) too. This study aimed at determining the prevalence of M...

The rheological regulation of the “three high” (high temperature, high density and high salinity) water-based drilling fluid is a worldwide problem due to the combined influence of temperature, solid content and salinity. This paper investigates the factors and regulation methods about rheological property of “three high” water based drilling fluid, and the effects of clay, salinity and weighti...

conclusions resistance to oxacillin and other antibiotics was high, and most of the isolates were found to be multi-drug resistance (mdr). plasmid analysis of representative s. aureus isolates also demonstrates the presence of a wide range of plasmid sizes, with no consistent relationship between plasmid profiles and resistance phenotypes. regular surveillance of hospital infections and monitor...

The combinations of antiretroviral (ARV) drugs have proven effective in controlling the progression of AIDS, but these benefits can be compromised by drug resistance. Thus, drug-resistance testing has become an important tool in the management of HIV-infected individuals.1 Drug resistance develops when mutations in the HIV virus proteins occur due to amino acid substitutions.2 Drug resistance t...

Mostaan, H., Safari, M.,

Weldability of high carbon steels due to the high percentage of carbon and consequently formation of martensitic structure is very poor. In this research, resistance spot welding of eutectoid high carbon steel 1075 is experimentally and numerically investigated from various points of view. The effect of welding current as one of the most effective parameters on failure mode, mechanical properti...

background the rapid emergence of antibiotic resistance, especially broad-spectrum antibiotics, resulted in the avid use of new potent antibiotics. ceftriaxone and ceftazidime, two third-generation cephalosporin, are usually used to manage complicated and uncomplicated infections. the use of cefepime in resistant infections is increasing gradually, which put this potent antibiotic at risk of re...
