This research work, which presents a simplified technique of modelling steel fibers, uses python algorithm that can be directly run in ABAQUS to automatically generate the location and orientation fibers rectangular ultra-high performance concrete specimen, so effect on properties such specimen investigated through numerical simulation. method is fast, applied structural members bigger dimensio...

remains of fossil herbivorous mammal from families like elephantidae, rhinocerotidae, giraffidae, bovidae and equidae have been studied systematically from a new fossiliferous horizon from the ilkhchi area in the southeastern high foothills of sahand. genera such as hipparion, gazella, samotherium, chilotherium and choerolophodon and some undetermined specimens are identified and reported. base...

Aortic aneurysm is a chronic degenerative condition associated with atherosclerosis. Recent studies have revealed that angiotensin (Ang) II plays important roles in atherosclerosis. In this study, to investigate the relationship between aortic aneurysm and Ang II, we measured the activities of the angiotensin (Ang) II-forming enzymes, angiotensin converting enzyme (ACE) and chymase-like enzyme,...

Laboratory experiments are an effective way to study the initiation and propagation of hydraulic fractures for complex stress level structure underground reservoirs. However, it is difficult observe directly in rock or mortar specimens. In this study, a kind transparent rock-like material whose tension–compression ratio reaches 1/9.5 at normal temperature was obtained, which helped us directly....

The Gen-Probe PACE 2 assay (Gen-Probe Inc., San Diego, Calif.) was compared with culture for the detection of Neisseria gonorrhoeae in endocervical specimens that were mailed to the laboratory. During mail transport, the specimens were exposed to extremes of hot and cold weather for several days before arriving in the laboratory. Specimens on culture plates deteriorated during transport, as evi...

SUMMARY The general lack of success that has attended attempts to establish tumor cell lines from solid specimens of breast carcinoma prompted our use of pleural effusions for this purpose. This paper summarizes tissue culture studies on five sequential pleural effusions from each of two patients with breast carcinoma. The morphology of cells in fresh specimens and cultures was documented by li...
