A revision is presented of the original description by Warren [ X-ray Diffraction , (1969), pp. 275–298. Massachusetts: Addison-Wesley] of the intensity distribution of powder-pattern reflections from f.c.c. metal samples containing stacking and twin faults. The assumptions (in many cases unrealistic) that fault proba…
ABSTRACT: Various procedures for extracting collagen and/or gelatin from megrim skins were compared on the basis of gelatin functional properties. It was possible to prepare a dry powder of soluble collagen with good viscoelastic and gelling properties, which can be converted into gelatin by dissolving at temperatures…
Abstract A new method for separate identification and determination of the spatial distribution of the two components of the energy intensity in an ultrasound bath (due to the ultrasound waves and cavitation activity) uses two media—cavitating (water) and noncavitating (silicon oil)—under the conditions of the acousti…
The orbital character, orientation, and magnetic polarization of the $\mathrm{O}\ensuremath{-}2p$ unoccupied states near the Fermi level ${(E}_{F})$ in ${\mathrm{CrO}}_{2}$ was determined using polarization-dependent x-ray absorption spectroscopy and x-ray magnetic circular dichroism from high-quality, single-crystal…
We investigate the three-dimensional morphology of the dendrite tip using the phase-field method. We find that, for low undercoolings, this morphology is ostensibly independent of anisotropy strength except for a localized shape distortion near the tip that only affects the value of the tip radius $\ensuremath{\rho}$…
The great reduction in thermal conductivity of skutterudites upon filling the ``void'' sites with rare-earth (RE) ions is key to their favorable thermoelectric properties but remains to be understood. Using lattice dynamic models based on first-principles calculations, we address the most popular microscopic mechanism…
The methods of the probability theory have been used in order to build up a model of hysteresis which is different from the well-known Preisach model. It is assumed that the system consists of large number of abstract particles in which the variation of an external control parameter (e.g., the magnetic field) may resu…
A theory is developed to explain various types of electronic collective behaviors in doped manganites ${R}_{1\ensuremath{-}x}{X}_{x}{\mathrm{MnO}}_{3}(R=\mathrm{La},$ Pr, Nd, etc. and $X=\mathrm{Ca},$ Sr, Ba, etc.). Starting from a realistic electronic model, we derive an effective Hamiltonian by utilizing the project…
As a means of effective utilization of fish water-soluble proteins (FWSP), which are mostly discarded into the waste water of seafood processing plants, the development and characterization of edible films from FWSP of blue marlin meat were investigated. The film-forming solutions were prepared from 3% FWSP solutions…
A detailed analysis of structural and position dependent characteristic features of helices will give a better understanding of the secondary structure formation in globular proteins. Here we describe an algorithm that quantifies the geometry of helices in proteins on the basis of their C alpha atoms alone. The Fortra…
The present investigation evaluates the effects of long-term, local delivery of insulin, insulin-like growth factor-1 (IGF-1), and basic fibroblast growth factor (bFGF) on fat-graft survival using a poly (lactic-co-glycolic-acid)-polyethylene glycol (PLGA/PEG) microsphere delivery system. Twelve-micrometer PLGA/PEG mi…
Previously, we reported the implantation of a single tissue engineered leaflet in the posterior position of the pulmonary valve in a lamb model. The major problems with this leaflet replacement were the scaffold's inherent stiffness, thickness, and nonpliability. We have now created a scaffold for a trileaflet heart v…

ABSTRACT: The effects of moisture sorption on physical properties of native and cross‐linked starch films in the glassy state were studied. Water played a dual role as a plasticizer or an antiplasticizer, depending on the physical property measured. Plasticizing effects were clearly evident in the case of the calorime…
ZnO thin films were epitaxially grown on α-Al2O3 (0001) substrate by radio-frequency (rf) magnetron sputtering. Among the ZnO films deposited at 550 °C, the film deposited at 80 W has the narrowest full width half maximum (FWHM) of x-ray diffraction (XRD) θ-rocking curve, 0.16°, indicating a highly c-axis oriented col…
Room-temperature white light emission can be obtained from a family of europium-containing hybrid materials called di-ureasils—organically modified silicates in which oxyethylene chains of different length are grafted by means of urea crosslinks to the siliceous backbone. It is demonstrated that the emission color may…
IEEE Electrical Insulation Magazine engineer might use this only for a basic understanding of the method and rather use a commercial FEA software that is widely available today. The book ends with a chapter on the design considerations in an avionics electronic package. Engineers who need to perform back-ofthe-envelop…
A general purpose transformation vector, designated pPha‐T1, was constructed for use with the diatom Phaeodactylum tricornutum Bohlin. This vector harbors the sh ble cassette for primary selection on medium containing the antibiotic zeocin, and a multiple cloning site flanked by the P. tricornutum fcp A promoter. pPha…
QPA (quantitative phase analysis) of polycrystalline materials using XRPD (X-ray powder diffraction) can be performed using the combined Rietveld and reference intensity ratio (RIR) methods, providing an estimate of both the crystalline and the amorphous phase in a mixture. Although the accuracy of estimates of the ph…
The impedance of the cubic perovskite BaZr 0.9 Y 0.1 O 3‐δ has been systematically investigated in dry and wet atmospheres at high and low oxygen partial pressures. In the grain interior, conductivity contributions from oxygen ions, electron holes, and protons can be identified. Below 300°C, proton conduction dominate…
