    Notes: Summary.  The nucleotide sequences of the entire protein coding regions of the thymidine kinase (TK) genes of macropodid herpesvirus type 1 (MaHV-1) and type 2 (MaHV-2) were determined. The coding region of the MaHV-1 TK gene was 984 bp long and was predicted to encode a polypeptide of 327 amino acids. The coding region of the MaHV-2 TK gene was 1020 bp long and encoded a polypeptide of 340 amino acids. Comparisons of their deduced amino acid sequences with those of fifteen other herpesviruses revealed close homology to those of other alphaherpesviruses, particularly to human herpesvirus type 1 (HHV-1) and type 2 (HHV-2).

    Notes: Abstract The competition between fusion-fission and deeply inelastic reactions in the Cl + Ni system has been studied by investigating the exit channelQ-value dependence of theZ-distributions of fission-like fragments. TheZ-, kinetic energy- and angular distributions of the fission-like fragments produced in the37Cl +64Ni system atE lab=170, 186 MeV and in the28Si +74Ge system atE lab=176 MeV have been measured by counter telescopes. TheZ-distribution of the37Cl +64Ni system was found to be essentially the same as that of the35Cl +62Ni system at the same bombarding energy. It is shown that this result can not be explained by the statistical fusion fission model but is consistent with a deeply inelastic model. A systematic study of the fission-like phenomenon in this mass region indicates that the maximum angular momenta for fusion reactions as well as the minimum angular momenta for DIC can be reproduced by the Bass model in the sliding limit (f=1.0) while the maximum angular momenta for fully energy-damped deeply inelastic reactions are governed by the strong interaction radius as predicted by the successive critical distance fusion model. The significance of these results are discussed.

    Notes: Using an Al/SiO2(wet)/Si0.9Ge0.1/n–Si/Al capacitor structure, effects of oxidation on bulk trap and interface states near the SiO2/SiGe interface are investigated. Two peaks at the energy levels of 0.23 eV (D1) and 0.40 eV (D2) below the conduction band edge are observed with the capacitance deep level transient spectroscopy (DLTS) method. The DLTS measurement results show a characteristic feature of interface states for the D1 peak. The interface state distribution obtained by the capacitance–voltage method also has a high density (6.9×1012/cm2 eV) peak at an energy level of 0.23 eV below the conduction band edge. The Si–O– dangling bonds are thought to be the source of the D1 peak. The annealing behaviors of the D2 peak show that D2 is a divacancy related bulk trap. The capture cross section and the trap density for the bulk trap D2 are 2.06×10−15/cm2 and 1.8×1014/cm3, respectively. The density of D2 is significantly reduced after low temperature postmetallization annealing. © 1999 American Institute of Physics.

    Notes: It is proposed that the nucleation and growth of the amorphous phase through the solid-state amorphizing reaction in thin-film diffusion couples can be predicted by using the concept of effective driving force. The effective driving force consists of two factors: (i) the thermodynamic driving force given by maximum free-energy difference between the physical mixture of binary elements and the amorphous phase (ΔGmax), and (ii) the kinetic factor given by a ratio of the effective radius of the interstitial site in the host matrix to the atomic radius of the diffusing species (Rm/d). From the comparison of reported experimental results, it is shown that the criterion of effective driving force holds well for predicting the nucleation of the amorphous phase in metal/silicon systems as well as that of metal/metal systems. In addition, the concept of effective driving force holds well for predicting the growth tendency of the amorphous phase in metal/silicon systems. © 1995 American Institute of Physics.

    Notes: The gel strength of the minced fish product made from the unwashed mullet mince was found higher than that of the washed product. Transglutaminase (TGase) was found in the water soluble fraction of mullet muscle. It's optimal temperature was at 30C to 35C and the optimal pH was 7.5 to 7.7. Increased setting time at 30C, increased the gel strength of the minced fish product produced from the unwashed mullet mince.p-Chloromercuribenzoate (PCMB), an inhibitor to TGase was added to the mullet mince up to 2.0 mM, the mince was set at 35C and then heated to 85C. The gel strength of the product was inversely correlated to the PCMB concentration, Y1= - 0.45X + 1.66 (r = 0.95). Studies of setting of the mullet mince at temperatures ranging 20 to 60C indicated that maximal gel strength was obtained at 35C, coinciding with the optimal temperature of TGase. Meat from 21.5 monthold grey mullet produced a minced product of higher gel strength than those produced from younger fish, although the muscle TGase activities were not significantly different.

    Notes: Abstract Recently metal oxides, especially tin oxides, have been investigated as negative electrodes in Li-ion batteries. Different compounds such as amorphous SnO2, SnO and SnSiO3 have been electrochemically cycled versus a metallic lithium electrode. In this study, the reversible capacities as well as the cycling behavior of crystalline SnO2 thin films and powders have been investigated. SnO2 powder exhibits a reversible capacity as high as 600 mAh/g over more than 50 cycles versus a metallic lithium electrode. Based on these results, we give clues for the future investigations of metal oxides as anodes in lithium ion batteries and discuss what can be the expected capacities of such negative electrodes.

    Notes: Abstract • Background: Scanty information is available on the changes in conformational structure and composition of human lens capsule in cases of hereditary congenital cataract. The purpose of this study was to use Fourier-transformed infrared (FT-IR) spectroscopy to determine the secondary structure and composition of hereditary cataractous human lens capsule, as compared with normal human lens capsule. • Methods: FT-IR spectroscopy with the Fourier self-deconvolution and curve-fitting program was performed, and second-derivative analysis was used to verify the peak positions and assignments of the IR spectra. • Results: The curve-fit FT-IR spectra revealed that the content of hydroxylysine and arginine were clearly higher in the lens capsule of the hereditary congenital patient, but the content of aspartic acid significantly lower, than in normal human lens capsules. The secondary conformational changes in a-helix, triple helix and random coil structures were important findings in the lens capsule of a hereditary cataractous patient. • Conclusion: Possible alterations in secondary structures and compositions of lens capsule are observed in the hereditary congenital cataractous patient by using FTIR spectroscopy with curve-fitting and second-derivative analysis.

    Notes: The atomic layer deposition technique has been applied to the growth of Al2O3 thin films on the substrates of Si(100), 100-nm-thick SiO2 covered Si(100) [SiO2/Si(100)], and 90-nm-thick TiN covered SiO2/Si(100). The growth rate of Al2O3 films was 0.19 nm/cycle and identical for all substrates employed under the surface controlled process. However, the optical properties of Al2O3 films were significantly affected by different substrates. The average interband-oscillator energy and refractive index parameter were determined to be 3.330 eV and 2.992×10−14 eV m2 for Al2O3 film grown on Si(100), while those for the film grown on SiO2/Si(100) were 4.492 eV and 2.074×10−14 eV m2, respectively. © 1997 American Institute of Physics.

    Notes: The thermal conductivities of α-Al2O3 and κ-Al2O3 wear-resistant coatings are measured using the 3ω method in the temperature range 80〈T〈600 K. The coatings are 13 μm thick and deposited by chemical vapor deposition on substrates of Co-cemented WC. The α-Al2O3 coating has a thermal conductivity comparable to sapphire at T〉300 K. The relatively small thermal conductivity of κ-Al2O3, a factor of ∼3 smaller than α-Al2O3, suggests that this metastable phase of alumina can be applied as an effective thermal barrier for cutting tools. © 1998 American Institute of Physics.
