in this study we report the rock magnetic properties of surface soil samples and their spatialvariability from the northernmost district of kerala to understand pedogenic processes and soil erosion. themagnetic signal is mainly from fine grained pedogenic magnetite as other sources like anthropogenic andlithogenic magnetite, bacterial magnetite and greigite are absent. the surface soil samples ...

the term “system” is defined as «elements standing interaction». this implies that a change in any given element should bring about changes in other elements of the system and thus may be used to identify the boundaries of a system. a system can be a machine, a man, or a community. each of these may be part of a greater system (super system) or include several smaller systems (subsystems). syst...

Relativistic elasticity on an arbitrary spacetime is formulated as a Lagrangian field theory which is covariant under spacetime diffeomorphisms. This theory is the relativistic version of classical elasticity in the hyperelastic, materially frame-indifferent case and, on Minkowski space, reduces to the latter in the limit c → ∞. The field equations are cast into a first – order symmetric hyperb...

Purpose Ni-Ti alloy has been increasingly applied to dental and medical devices, however, it contains nickel, which is known have adverse effects on the human body. The purpose of this study was form a nickel-free surface oxide layer by electrolytic treatment for better biocompatibility. Methods Ni-49.15Ti (mol%) used, performed in electrolytes under 50 V 30 minutes. were composed lactic acid, ...

BACKGROUND To evaluate the effect of perfusion status on elasticity measurements of different compartments in the kidney using shear wave elastography (SWE) both in vivo and ex vivo. METHODS Thirty-two rabbit kidneys were used to observe the elasticity variation caused by renal artery stenosis and vein ligation in vivo, and six beagle kidneys were studied ex vivo to explore the effect of rena...

BACKGROUND Quantifying passive stretching responses of individual muscles helps the diagnosis of muscle disorders and aids the evaluation of surgical/rehabilitation treatments. Utilizing an animal model, we demonstrated that shear elastic modulus measured by supersonic shear wave elastography increases linearly with passive muscle force. This study aimed to use this state-of-the-art technology ...
