    Notes: In order to determine the optimum method for extraction of the entire flavour profile of sausages, three extraction techniques, solvent extraction (SE), purge and trap (PT), and simultaneous distillation extraction (SDE), were compared. Similarly, to effectively analyse the volatile compounds of low-fat (〈3%) and regular-fat (approximately 15%) sausages, three isolation techniques were investigated and gas chromatography (GC) and gas chromatography–mass spectrometry (GC/MS) were used for final identification of compounds. A total of thirty-three volatile compounds were identified in the sausages by SDE, twelve by SE, and nine by PT. In the SE method, fats interfered in the extraction of some volatile components, resulting in lower recovery and longer isolation time when compared with the other two methods. The PT method might not be a good extraction method because of the loss of heterocyclic compounds. However, the SDE method showed greater yields and recognized more volatiles when compared with SE. Furfural, trans-caryophyllene, and myristicine were the predominant volatile compounds extracted by SDE. These results suggest that the SDE method is the most efficient method in isolating volatile compounds in both regular- and low-fat sausages. The amounts of volatile compounds, such as, 4-acethyl-3-methyl pyrazole, 1,4-dimethyl benzene, p-ethylguaiacol and β-caryophyllene were higher in regular-fat sausages; however, the amounts of myristicine and hexadecanoic acid were higher in low-fat sausages.

    Notes: N-type ZnTe layers with high electron concentration are grown by molecular-beam epitaxy using aluminum as the donor species. The ZnTe:Al layers show a high structural quality with a narrow x-ray diffraction linewidth (24 arcsec) and a high carrier concentration up to n=4×1018 cm−3 with low resistivity (ρ=0.017 Ω cm). The dependence of the electron mobility on the carrier concentration suggests that the dominant scattering mechanisms in the ZnTe:Al layers are ionized impurity scattering and polar optical phonon scattering. The photoluminescence spectrum of moderately doped ZnTe layers shows strong Al–donor-related bound exciton lines: I2 (2.378 eV) and donor–acceptor pair emission (zero phonon energy=2.324 eV) with a weak deep-level emission (2.19 eV). Highly Al-doped layers show an increase in the deep-level emission intensity and a decrease in carrier mobility, which are interpreted in terms of the increase in the carrier compensation. © 2001 American Institute of Physics.

    Notes: Moisture, total fat and cholesterol of goat liver, kidney, heart, Longissimus dorsi (LD) and Biceps femoris (BF) muscles were determined. Samples were taken from 10 Alpine and 10 Nubian post-weaned goat kids that were fed a complete diet treated with 4 levels of Ca for 12 wk before slaughter. Mean moisture (%), total fat (%) and cholesterol (mg/100g wet tissue) for the respective tissues were: 75.9, 3.26, 214.2; 82.0, 3.14, 276.7; 79.2, 4.32,167.5; 79.2, 2.27, 57.8; 80.4, 2.03, 69.5. These goats contained less cholesterol in liver and more cholesterol in kidney and heart than the same organs in mutton samples reported previously. Fat and cholesterol were significantly (P 〈 0.01) influenced by dietary Ca, breed and tissue, while moisture was affected only by tissue.

    Notes: : The combined influence of preheat treatment, mixing with various proteins, and the addition of microbial transglutaminase (MTGase) on the physicochemical properties of bovine collagen-peptide (BCP) gel was investigated. The preheat treatment and the mixing with various proteins contributed to the enhancement of the gel strength and polymerization of BCP. The gel made with 0.1% MTGase showed the highest breaking strength. The melting point of the preheated BCP gel was higher than that of the unheated one (P 〈 0.05). The gel made with a combination of preheated BCP-casein or preheated BCP-soybean protein showed a higher melting point than that made with preheated BCP alone (P 〈 0.05). The sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) pattern of the mixture of preheated BCP with casein or soybean protein showed that the protein bands with relatively low molecular weights disappeared and the bands with relatively high molecular weights increased. Observation by a scanning electron microscope revealed that the preheated BCP gel prepared with MTGase had a well-defined cross-linked network and showed some clumps of aggregated proteins. These results show that preheating, mixing with other proteins and MTGase treatment, are effective ways to make BCP a fine biopolymer.

    Notes: A CoSi2 buffer layer was prepared in polycrystalline silicon (polysilicon) plug for preventing an undesired microvoid between the polysilicon plug and Ir/Ti diffusion barrier. Since the microvoid generates random function fail, resulting in low wafer yield of a 4 Mb ferroelectric random access memory device, we developed the thermally stable CoSi2 buffer layer for eliminating the random single bit fails. The ferroelectric capacitors using the CoSi2 buffer layer showed a low contact resistance of 96 Ω per contact in 1k serial contact array with contact size of 0.6 μm, and also exhibited great ferroelectric properties such as remnant polarization and coercive voltage of 20 μC/cm2 and 1.2 V, respectively. Scanning electron microscopy analyses confirmed that no microvoid was formed between the interface between the Ir/Ti barrier layer and the CoSi2 buffer layer. © 2002 American Institute of Physics.

    Notes: We present the results of the formation of the InAs quantum dots (QDs) on the (100) In1−xAlxAs(InAlAs)/InP substrate by using relaxed InAlAs buffer layers with different compositions. Variations of surface morphology of InAs QDs as a function of InAs–InAlAs lattice mismatch have been evaluated by atomic force microscopy. When the lattice mismatch increases from 2.4% to 4.2%, the size of QDs decreases, and the density of QDs increases. Each of these dependences can be fitted to a power function of the misfit unless the Al diffusion, roughness of the buffer layer, and/or the ripening of small dots modify the size and density.© 2001 American Institute of Physics.

    Notes: A reliable Ir diffusion barrier was prepared on polysilicon plugged substrate with a contact size of 0.6 μm. Using a Ti adhesion layer and stress-relief process, it was possible to integrate the Ir barrier into a high density 4 Mb ferroelectric random access memory device. After heat treating sol-gel derived Pb(Zr1−xTix)O3 (PZT) films at 700 °C, the Ir barrier contact displayed an ohmic behavior and showed a low resistance of 130 Ω per contact in 1k serial contact array. The PZT films on Pt/IrO2/Ir poly-plugged substrate exhibited excellent ferroelectric properties such as remnant polarization and coercive voltage of 25 μC/cm2 and 1.15 V, respectively. Auger depth profile and transmission electron microscopy analyses confirmed that no appreciable oxidation was formed between the Ir barrier and the polysilicon plug. © 2000 American Institute of Physics.

    Notes: The growth of high quality CdTe epitaxial films on p-InSb(111) by a simple method of temperature gradient vapor transport deposition was carried out to investigate the possibility of the existence of a two-dimensional electron gas with high mobility at CdTe/InSb heterointerfaces. From the x-ray diffraction analysis, the grown layer was found to be a CdTe epitaxial film. Photoluminescence measurements at 15 K showed that a CdTe film grown on InSb(111) in the temperature range between 180 and 280 °C appeared to have an optimum crystal perfection at a substrate temperature of about 245 °C. These results also indicated that the CdTe films grown above 245 °C contained a significant problem due to interdiffusion from the InSb substrates during the growth.

    Description: Background Peri-coronary adipose tissue attenuation expressed by fat attenuation index (FAI) on coronary CT angiography (CCTA) reflects peri-coronary inflammation and is associated with cardiac mortality. CCTA also provides two-dimensional and three-dimensional quantification of the individual component of atherosclerotic plaque and entire vessel. The atherosclerotic burden or disease extent in entire epicardial coronary arteries provides prognostic information in patients with coronary artery disease. Purpose This study sought to explore the prognostic significance of FAI values and whole vessel and lesion plaque quantification on CCTA in stable patients with intermediate epicardial stenosis evaluated by fractional flow reserve (FFR). Methods A total of 277 patients (277 lesions) with intermediate coronary stenosis who underwent FFR measurement and CCTA were studied. FAI was assessed by the crude analysis of the mean CT attenuation value (−190 to −30 Hounsfield units; higher values indicating inflammation) on CCTA. CT findings including whole vessel and lesion plaque quantification, and target vessel myocardial mass were investigated. Major adverse cardiovascular outcome (MACE) was defined as all cause death, cardiac death, myocardial infarction, unplanned revascularization, and heart failure requiring admission. Survivals from MACE were assessed. Results The mean FAI and the median FFR values were −71.6 and 0.77, respectively. FFR values were weakly albeit significantly correlated with FAI values. (r=−0.016, P=0.008.) MACE was occurred 43 (15.5%) patients during 5 years F-up. ROC analyses revealed that best cut-off value of FAI to predict MACE was −73.1. Kaplan-Meier analysis revealed that lesions with FAI ≥−73.1 had a significantly higher risk of MACE. (Chi-square 5.5, P=0.019) FFR values and the percutaneous coronary intervention were not predictive of MACE. Multivariate COX proportional hazards regression analysis revealed that age, remodeling index, and lesions with FAI ≥−73.1 were independent predictors of MACE. Conclusion The peri-coronary inflammation evaluated by FAI and CT remodeling index enhances cardiac risk prediction in chronic coronary syndrome patients with intermediate lesions. Non-invasive comprehensive CT assessment may help identify high risk patients of subsequent clinical events and provide enhanced patient management.
