Dietary consistency has been shown to influence cross-sectional area and fiber type composition of the masticatory muscles. However, little is known about the effects of dietary consistency on masticatory muscle fiber architecture. In this study, we explore the effects of dietary consistency on the internal architectu…
With two different methods, ibuprofen was entrapped into porous hollow silica nanoparticles (PHSNs) carriers, which were synthesized through a sol-gel route by using CaCO3 nanoparticles as the inorganic templates. By employing pressured CO2 as the loading medium, the amount of ibuprofen that was pressed into the carri…
The self-organization of citrate- and acrylate-stabilized gold nanoparticles onto SiO2/hydroxyl-, amino- and nitro-terminated surfaces was investigated as a function of pH. Bare clean Si/SiO2 substrates were used as the SiO2/hydroxyl-terminated surfaces and self-assembled monolayers (SAM) of (3-aminopropyl)trimethoxys…
The potential use of sustainable polymer based composites, obtained from renewable resources, is revised in terms of properties and envisaged applications. Using the typical specifications required within the automotive industry as reference, the potential of these composites is evaluated and some alternative routes f…
Zinc tin oxide based thin-film transistors are fabricated via reactive magnetron sputtering using a metallic zinc/tin alloy target. The oxygen partial pressure and total sputtering pressure are explored. An oxygen partial pressure and total sputtering pressure of 0.8 and 30mTorr, respectively, are found to be optimal.…
A glyph-based method for visualizing the nematic liquid crystal alignment tensor is introduced. Unlike previous approaches, the glyph is based upon physically-linked metrics, not offsets of the eigenvalues. These metrics, combined with a set of superellipsoid shapes, communicate both the strength of the crystal's unia…
A novel apparatus for gas phase heterogeneous catalysis kinetics is described. The apparatus enables fast isotopic transient kinetic analysis (ITKA) to be performed in which both the gaseous and adsorbed species inside the catalytic reactor are monitored simultaneously with rapid-scan transmission Fourier transform in…
A nonreciprocal left-handed transmission line is proposed and investigated, which is composed of a normally magnetized ferrite microstrip line periodically loaded with inductive stubs but without capacitive loading. The circuit configuration becomes simpler than that of a nonreciprocal left-handed transmission line wi…
A small drug molecule, L-DOPA, was converted into well-defined dendritic macromolecules. Their monodisperse nature was shown by NMR, MALDI-TOF-MS, and PAGE. A third-generation L-Dopa dendrimer contained 30 L-Dopa residues, which made up its core, branches, and periphery. Individual L-Dopa moieties in the dendrimer wer…
Thermoplastic natural rubber (TPNR) hybrid composite with short glass fiber (GF) and empty fruit bunch (EFB) fiber were prepared via the melt blending method using an internal mixer type Thermo Haake 600p. The TPNR were prepared from natural rubber (NR), liquid natural rubber (LNR) and polypropylene (PP) thermoplastic…
Large single crystals of oxygen-deficient Sr6Co5O(15-delta) compounds, i.e., Sr6Co5O14.70 and Sr6Co4.9Ni0.1O14.36, were obtained by using K2CO3 flux in the presence of additives of transition metal oxides. The single-crystal structure determination shows that the structures of Sr6Co5O14.70 and Sr6Co4.9Ni0.1O14.36 crys…
A horizontal wicking experiment is proposed to measure the wicking behavior of textiles. A syringe supplying a continuous flow of distilled water is in contact with the absorbing fabric resulting in a wicking region. The increase in wicking area or the wicking area after a certain time is recorded with a digital camer…
Nanosized 10 mol% MgO‐doped ZrO 2 powder was prepared via coprecipitation, followed by a washing–drying–calcining treatment. Water, ethanol, and a mixture of water and ethanol (volume ratio 1:1) were, respectively, used as solvents for precipitating and washing. These solvents had great influence on the dispersion of…
Heterostructured ZnO–ZnS core-shell nanotube arrays with the diameters of 50–80nm and lengths up to 1μm were synthesized by a two-step chemical reaction. First, the ZnO layer was grown by atomic-layer deposition. It was found that the preferred growth orientation was strongly dependent on the substrate temperature. Af…
The fabrication of the next generation of complex oxide thin film-based micro and nanoscale devices, such as, for example, low and high density nonvolatile ferroelectric random access memories (FeRAMS), high-dielectric constant (K) high-frequency devices, and the next generation of complimentary metal oxide semiconduc…
Laboratory-scale experiments were performed with Zircaloy-4 fuel cladding, irradiated to 39 and 44 GWd/t at a PWR, for evaluating high burn-up fuel rod behavior in a loss-of-coolant accident. Short test rods, fabricated with the cladding were heated, isothermally oxidized at 1,303 to 1,451 K in steam flow, and quenche…
This article reviews the body of work aimed at elucidating the mechanisms of action by which natural products of plant origin exert a vasodilatory effect at the level of the vasculature. The search was restricted to 4 mechanisms: the nitric oxide system and (or) reactive oxygen species, the eicosanoid system, potassiu…
In the present study, we describe the features of programmed cell death of the ovarian nurse cells occurring during vitellogenesis of the silkmoth Bombyx mori. At developmental stage 5, the nurse cells occupy one-half of the follicular volume and obtain a rather spherical shape, while the nurse cell nuclei appear larg…
For the purpose of the developing Pb-free piezoelectric ceramics, the dielectric and piezoelectric properties of two series of KNbO 3 –NaNbO 3 –LiNbO 3 –SrTiO 3 (KN–NN–LN–ST) perovskite ceramics, namely 0.47KN–0.47NN–(0.06- x )LN– x ST (0≤ x ≤0.06) and 0.45KN–0.45NN–(0.10- y )LN– y ST (0.02≤ y ≤0.10) were investigated…
The identification of biological reference conditions specific to each type of water body is essential for the development of sound biological indicators and criteria. The purpose of the present study was to establish the reference conditions of each stream type sampled in southern Québec (Canada) using benthic diatom…
