Weakly cemented rocks are characterized by low strength, loose structure, and easy disintegration. High-intensity mining activities can damage rupture such rock bodies induce damage, as flaking roofing on roadways. To reveal the intensity influence weakly rocks’ deformation a numerical particle flow model of sandstone was established based theory. Uniaxial compression simulation tests were cond...

a 74-year-old male patient was admitted to our emergency department with post-mi angina. on account of the anginal complaint that continued for three days, a coronary artery angiography was undertaken. a percutaneous transluminal coronary angioplasty was performed, followed by the implantation of a coronary stent, and coronary perfusion (timi-3) was achieved in the left anterior descending arte...

pneumatic rectosigmoid rapture is usually occurred following the inappropriate fun by direct entering a high volume of the air through the pneumatic device to the anus. such an event was reported for the first time in 1904 by stone. diagnosis and treatment of such injuries are often delayed because of some social limitations and preventing the patient form explaining the event. colon sigmoid ru...

Partial rupture of the distal biceps tendon is a relatively rare event, and various degrees of partial tendon tears have been reported. In the current study four patients with partial atraumatic distal biceps tendon tears (mean age, 59 years; range, 40-82 years) are reported. In all four patients, a common clinical pattern emerged. Pain at the insertion of the distal biceps tendon in the radius...
