Infrared microspectroscopy is a tool with potential for studies of the microstructure, chemical composition and functionality of plants at a subcellular level. Here we present the use of high-resolution bench top-based infrared microspectroscopy to investigate the microstructure of Triticum aestivum L. (wheat) kernels and Arabidopsis leaves. Images of isolated wheat kernel tissues and whole whe...

The transition from healthy myocardium to hypertensive heart disease is characterized by a series of poorly understood changes in myocardial tissue microstructure. Incremental alterations in the orientation and integrity of myocardial fibers can be assessed using advanced ultrasonic image analysis. We used a modified algorithm to investigate left ventricular myocardial microstructure based on a...

From numerical point of view, analysis and optimization in computational material engineering require efficient approaches for microstructure representation. This paper develops an approach to establish an image-based interpolation model in order to efficiently parameterize microstructures of a representative volume element (RVE), based on proper orthogonal decomposition (POD) reduction of dens...

We develop a network model of bone microstructure and dynamics, BoneNET, which is capable of quantitative assessment of Bone Mineral Density (BMD) and bone remodelling dynamics. First, we introduce a network model of bone microstructure by describing structural properties and process of bone network modelling. Secondly, we explain a mathematical model of bone microstructure by analysing the den...

We report on observations of microstructure at 4.85 and 1.41 GHz of pulsars strong enough for the observation of single pulses with time resolution between 7 µs and 160 µs. All five pulsars observed at 4.85 GHz show microstructure in a large fraction of their pulses. We confirm that microstructure seems to be a common property of the pulsar emission mechanism and not only an additional feature ...

in the present study, the effect of porosity on the cathode microstructure (50:50 wt. % lsm: ysz) of a solid oxide fuel cell (sofc) has been examined. a 3-d finite element method for mixed ionic and electronic conducting cathodes (miec) is presented to study the effects of porosity on cell performance. each microstructure was realized using the monte carlo approach with the isotropic type of gr...

in this study, the changes in microstructure of hp-nb cast heat resistant steel after 8 years of service at high temperatures were investigated. study of microstructure using optical microscopy (om) and scanning electron microscopy (sem) equipped with an energy dispersive spectrometry (eds) showed that the microstructure of this steel in as-cast condition includes an austenitic matrix, and that...

this paper presents an investigation on the effect of temperature and raw material on microstructure of fine cellular foam used as the insulation of coaxial cables. a set up was prepared and used to produce fine cellular foamed insulation. as the physical  blowing agent, butane was used. the effect of temperature on the microstructure of polyethylene (pe) was worth to note. at high temperature,...

This research aims to deepen the understanding of the interaction mechanisms between microwave and matter in a metal-ceramic system based on in situ synchrotron radiation computed tomography. A special internal "core-shell" microstructure was discovered for the first time and used as an indicator for the interaction mechanisms between microwave and matter. Firstly, it was proved that the microw...

Elastic metamaterials have unusual microstructures that can make them exhibit unusual dynamic behavior. For instance, if treated as classical elastic solids, these materials may have frequency-dependent effective mass densities which may become negative in certain frequency range. In this study, an approach for developing microstructure continuummodels to represent elastic metamaterials was pre...
