Buckling of Steel Portal Frames Considering Material Non-Linearity
Diyala Journal of Engineering Sciences, 2015 In this research, an experimental study was carried out to investigate the failure modes of eight frames with IPE cross-sections. The study was conducted by subjecting these frames to two equal concentrated loads (applied directly on columns); however ...

Research on Energy Dissipation Laws of Coal Crushing under the Impact Loads
Shock and Vibration, 2021 Dynamic crushing characteristics of coals are closely related with energy absorption and release of coals under certain strain rate. Hence, it is necessary to investigate energy dissipation laws of coal crushing under the impact loads with different ...

Analysis of Energy Transmission and Deformation Characteristics of Coal-Rock Combined Bodies
Geofluids, 2022 A coal-rock system is a common combination form in coal mines. In order to explore the energy interchange law of a coal-rock combined body and the interaction relationship between the two bodies, loading tests of coal-rock combined bodies with different ...

Effects of inbreeding and genetic modification on
, 2010 Background Genetic modification of mosquitoes offers a promising strategy for the prevention and control of mosquito-borne diseases. For such a strategy to be effective, it is critically important that engineered strains are competitive enough to serve ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]
, 2016 Density is a fundamental property of porous media such as snow. A wide range of snow properties and physical processes are linked to density, but few studies have addressed the uncertainty in snow density measurements.

The strain-energy density function of the urinary bladder.
The Tohoku Journal of Experimental Medicine, 1982 In previous articles we proposed a finite deformation theory of the urinary bladder. The present paper is the third article in a series of these works. Our aim is to study more carefully the strain-energy density function W of the urinary bladder, because the determination of this function W is one of the central problems in the finite deformation ...
