The article is devoted to modification of the impact devices Leeb hardness testers for implementation dynamic instrumented indentation method. results obtained made it possible construct a load–displacement curve using primary EMF signals and determine values dissipated elastic body energy, maximal load indentation, residual penetration depth geometric parameters region, namely contact area ind...

The present paper deals with the mixed mode fracture analysis of a weakened orthotropic half-plane with multiple cracks propagation. The orthotropic half-plane contains Volterra type glide and climb edge dislocations. It is assumed that the medium is under in-plane loading conditions. The distributed dislocation technique is used to obtain integral equations for the dynamic problem of multiple ...

A new balanced-force algorithm is presented for modeling interfacial flow with surface tension. The algorithm is characterized by a pressure-correctionmethodwith the interfaces represented by volume fractions.Within this flow algorithm, we devise a continuous (e.g., continuum surface tensionmodel) and a sharp (e.g., a ghost fluidmethod) interface representation of the surface-tension-induced in...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...

The development and design of the biocompatible and biodegradable thermodynamically stable micellar and microemulsion transparent dispersions to reduce the free and unbounded drugs concentration in the blood is a basic challenge in field of drug efficacy and bioavailability of drugs. In the current work, solubilization capacity of the drug (Tocopherol), oil (Ethyl Butyrate), and oil+drug (1:1 m...

Human induced pluripotent stem (hiPS) cell culture using Essential 8™ xeno-free medium and the defined xeno-free matrix vitronectin was successfully implemented under adherent conditions. This matrix was able to support hiPS cell expansion either in coated plates or on polystyrene-coated microcarriers, while maintaining hiPS cell functionality and pluripotency. Importantly, scale-up of the micr...

Despite the importance of multiaxial failure of trabecular bone in many biomechanical applications, to date no complete multiaxial failure criterion for human trabecular bone has been developed. By using experimentally validated nonlinear high-resolution, micromechanical finite-element models as a surrogate for multiaxial loading experiments, we determined the three-dimensional normal strain yi...

The successful development of an optimal canopy vegetation index dynamic model for obtaining higher yield can offer a technical approach for real-time and nondestructive diagnosis of rice (Oryza sativa L) growth and nitrogen (N) nutrition status. In this study, multiple rice cultivars and N treatments of experimental plots were carried out to obtain: normalized difference vegetation index (NDVI...

The paper presents a methods to retrieve the speed of the sea surface from Along Track Interferometry (ATI) data beside the typical use for target speed retrieval, which is also mentioned. The describe technique provides for a data prefiltering in order to obtain the necessary accuracy because of the law speed range of the currents. Furthermore, an example of target velocity estimation is provi...

We examine the correlation between the plasmon field distribution and the sensitivity enhancement for both reflectionand transmission-type localized surface plasmon resonance (LSPR) biosensors with surface-relief gold nanogratings. In our calculation, the near-field characteristics are obtained from the finite-difference time-domain method and compared with the refractive index sensitivity as a...
