uniaxial compressive strength (ucs) and elastic properties of rocks play a major and vital role for the design of any engineering structure. the specimen diameter size is one of the main factors that influencing on ucs, elasticity modulus and poisson’s ratio (e and υ). here, an attempt has been made to investigate the effect of specimen diameter size on ucs, e and υ. moreover, we studied the co...
As a low melting point alloy, Sn58Bi alloy plays unique role in many fields. However, the brittleness of is limitation that has to be addressed for wider applications. According previous studies, third element addition favorable improved ductility, which attributable structure refinement. Therefore, laser beam powder bed fusion technology was adopted prepare components. Additionally, as-printed...
In this study, X-ray computed tomography (X-ray CT) in situ compressive loading was used, combination with digital volume correlation (DVC), to analyze the localized damage behavior of cement mortar, cracking process, microstructural changes, and strain distribution. By using CT, it possible identify three-dimensional structure two-dimensional internal morphology compressed mortar. The developm...
Background/Aim: To evaluate void volumes in oval-shaped root canals obturated with three different obturation systems using microcomputed tomography (micro-CT). Material and Methods: Twenty-four distal roots of mandibular molar teeth were prepared randomly divided into groups (n = 8 each group). The single cone (SC), GuttaCore (GC), warm vertical compaction (WVC) techniques. Each specimen was s...
Abstract Strongyloidiasis is caused by infestation with Strongyloides stercoralis, a free living tropical and semitropical soil helminth that has a larval form that penetrates intact skin. Clinical manifestations may be varied from an asymptomatic infection in immunocompetent hosts to a diffuse and fatal form in immunocompromised hosts. We report a 56-year-old man from Dezful (sou...
background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...
BACKGROUND Histopathology is the only accepted method to measure and stage the breast tumor size. However, there is a need to find another method to measure and stage the tumor size when the pathological assessment is not available. Micro-computed tomography. (micro-CT) has the ability to measure tumor in three dimensions in an intact lumpectomy specimen. In this study, we aimed to determine th...
