This paper investigates the phenomenon of slant fracture observed in stable tearing tests of many ductile materials, where an initially flat crack, loaded under remote Mode I conditions, tends to grow into a slant crack and stay in the slant configuration until final fracture. In an effort to identify potential reasons why cracks prefer to grow in a slant manner, three-dimensional finite elemen...

background: although, nontuberculous mycobacteria can cause disease in different organisms, they usually are not reported in most countries because scientists in general consider them as non-pathogens. but, increasing nontuberculous mycobacteria diseases occurrence has changed this belief. nevertheless, there is no meta-analysis review about prevalence of nontuberculous mycobacteria in iran. me...

conclusion according to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. we resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. the complication rate is very low. the us-assisted percutaneous liver biopsy should be used for all cases. results a total of 1018 patients we...

The paper proposes to compare static and dynamic properties of three structural adhesives selected for the integration optical space systems. These comparisons are based on an original methodology using test drop weight impact determine best shock-strength candidate. In a first section, design rig integrating modified Arcan fixture is described. Then validity discussed simplified case thanks an...

background : lung cancer is still the leading cause of cancer- related deaths and most of themâ  are normally diagnosed in late stages, so there is an urgent need to establish reliable tools for the identification at early stages of the disease. in this study, we use an eleven gene signature test to examine lung biopsy specimens for diagnostic, prognostic & therapeutic purposes. methods : bronc...
