an understanding of the strength of rice grains as affected by moisture content and temperature is important for analysis and prediction of cracking and/or breakage behavior during handling and processing. further, the magnitude of these properties at various moisture contents and temperatures is needed for the accurate design of milling machinery so that grain damage is minimized. to determine...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

The mechanical characteristics of rock salt have an important influence on the safety of the salt cavity. The acoustic emission (AE) technique was used to analyze the generation of microcracks in rock salt under uniaxial compression condition. By monitoring acoustic emission in whole process of stress strain curve under uniaxial compression test, the damage characteristic of rock salt is obtain...

Introduction: Recently, new plates with locking screws have been developed and used for medial open-wedge high tibial osteotomy (HTO). The purpose of this study was to evaluate and compare biomechanical properties of different internal fixations in open-wedge HTO using the two currently available locking plates. Methods: Eight paired fresh-frozen cadaveric lower extremities were vertically embe...

AIMS A comprehensive description of transcatheter heart valve (THV) failure has not been performed. We undertook a systematic review to investigate the aetiology, diagnosis, management, and outcomes of THV failure. METHODS AND RESULTS The systematic review was performed in accordance with the PRISMA guidelines using EMBASE, MEDLINE, and Scopus. Between December 2002 and March 2014, 70 publica...

Heart failure is a disease that may present with various presentations depending on different etiological factors. External pressure the heart one of rare causes can cause failure. Here, we presented 73-year-old female patient inoperable endometrial cancer who developed due to hiatal hernia compression.

The nanomechanical response properties of 3C-SiC nanowires are investigated using molecular dynamics simulation with Tersoff bond-order interatomic potential. Under axial compression and tensile strain, the computed Young’s modulus and structural changes at elastic limit do not depend appreciably on the diameter of the nanowire except for the nanowire of the smallest diameter 1 nm under compres...

The result showed that the brittle failure was extinct, and the new-type shear walls had good deformability whose ductility factors were over 4.3. The axial compression ratio had significant influence on the mechanical properties of the new-type shear walls. As the increscent of the axial compression ratio, the shear capacity and initial stiffness were improved, but the energy-dissipating capac...

IVF is one of the most comprehensively registered interventions in clinical medicine. IVF is regarded as safe with very few complications. We report a woman who developed acute renal failure due to compression of both ureters from enlarged stimulated ovaries. The condition was diagnosed using ultrasound and magnetic resonance imaging (MRI). The condition was treated with insertion of double-J s...

Retrograde locked intramedullary nailing has gradually been widely used to treat femoral supracondylar fractures. Because a standard femoral supracondylar nail has unique disadvantages: high price and potentially inducing a femoral shaft stress fracture, it is often replaced by a traditional femoral or tibial locked nail. A biomechanical comparison was therefore made between both traditional lo...
