Cupriavidus sp. strain CNP-8 isolated from a pesticide-contaminated soil was able to utilize 2-chloro-4-nitrophenol (2C4NP) as a sole source of carbon, nitrogen and energy, together with the release of nitrite and chloride ions. It could degrade 2C4NP at temperatures from 20 to 40 °C and at pH values from 5 to 10, and degrade 2C4NP as high as 1.6 mM. Kinetics assay showed that biodegradation of...

The results of magnetostriction constant A, of multilayer Ni-Ag films are reported. The measurements have been performed at room temperature using strain modulated ferromagnetic resonance method. The magnetostriction constant As depends linearly on the inverse Ni layer thickness. This effect is suggested to be due to the reduced local symmetry in interfaces.

The new stand called DURAMETR with a computer program based on LabVIEW software to investigate textile creep is described. An analysis of filament creep under constant load is presented. A comparative analysis of changes of filament strain under constant load obtained from DURAMETR, and the INSTRON tester which uses the XII cyclic program is presented.

Strain rate dependent bone fracture thresholds are investigated to improve the understanding of dynamic lower extremity injury criteria for threats at different rates of compressive impact. Cortical bone specimens were extracted from eleven bovine femur bones and compressed at constant strain rates (10 s, 10 s, 10 s and 3×10 s). The experimental bone response is fitted with a viscoelastic const...

Brillouin scattering in perfluorinated graded-index (PFGI-) polymer optical fibers (POFs) has been extensively studied for structural health monitoring, including seismic diagnosis. Here, we measure the propagation loss of PFGI-POFs at telecom wavelengths as a function of large applied strain (up to 100%) at three optical powers and as a function of strain rate at a constant optical power. The ...

background recently, assessment of the atrial motion and deformation indices obtained via doppler myocardial imaging (dmi) has been proposed as a new method of exploring the atrial function. objective our aim was to assess the right atrial (ra) regional function using myocardial velocities, strain, and strain rate imaging (sri) and compare it with the function of the inter-atrial septum (ias) a...

BACKGROUND Although left atrial (LA) dysfunction is common in heart failure with preserved ejection fraction (HFpEF), its functional implications beyond the reflection of left ventricular (LV) pathology are not well understood. The aim of this study was to further characterize LA function in HFpEF patients. METHODS AND RESULTS We performed cardiac magnetic resonance myocardial feature trackin...

Numerical methods like the finite element (FE) method are often used to evaluate the reliability of electronic packages. However, the accuracy of non-linear numerical analyses should be confirmed by experimental measurements. In this study, we evaluated the strain distribution in flip chip (FC) packages with multi-layered printed circuit boards (PCBs) by combining the digital image correlation ...
