Some finite difference methods for a kind of GKdV equations
Authors: Lai X. , Cao Q. 
Published: August 2006

AbstractIn this paper, some finite difference schemes I, II, III and IV, are investigated and compared in solving a kind of mixed problem of generalized Korteweg‐de Vries (GKdV) equations especially the relative errors. Both the numerical dispersion and the numerical dissipation are analysed for the constructed difference scheme I. The stability is also obtained for scheme I and the constructed predictor–corrector scheme IV by using a linearized stability method. Other two schemes, II and III, are also included in the comparison among these four schemes for the numerical analysis of different GKdV equations. The results enable one to consider the relative error when dealing with these kinds of GKdV equations. Copyright © 2006 John Wiley & Sons, Ltd.
A Novel Concept for Photovoltaic Cells: Clusters of Titanium Dioxide Encapsulated within Zeolites as Photoactive Semiconductors
Authors: Álvaro Mercedes , Carbonell Esther , Atienzar Pedro , García Hermenegildo 
Published: August 2006

AbstractDiscrete clusters of TiO2 (of only a few titanium atoms) are prepared within the internal micropore space of zeolite Y (4.8 wt % Ti loading) and characterized by Raman spectroscopy (rutile‐ and anatase‐like structures), electron microscopy combined with elemental analyses (coincident Si and Ti spatial distribution), and X‐ray diffraction (minor zeolite crystallinity decrease). The parent TiO2@Y sample is modified either by adsorption of acid‐organic compounds (benzoic and 4‐aminobenzoic acids or catechol) or by nitrogen doping. After modification, the optical UV/Vis spectrum of the parent TiO2@Y (onset of the absorption band at wavelengths <300 nm and bandgap of 4.2 eV) changes, and the appearance of new bands expanding to the visible region is observed. In contrast to the inactive zeolite Y matrix, all the zeolite‐encapsulated TiO2 species exhibit a photovoltaic response. The influence of the I2/I3− concentration in the electrolyte solution on the temporal profile of the photovoltage clearly shows that I2/I3− is also a suitable carrier for the positive charge in zeolite‐based photovoltaic devices. The photocurrent response and the efficiency of the photovoltaic cell based on zeolite‐encapsulated TiO2 materials depend on the nature of the organic modifier and on the N‐doping. The most efficient photovoltaic cell is that based on N‐doped TiO2@Y, which exhibits a VOC (voltage at open circuit) of 270 mV, an ISC of 5.8 μA (current at short circuit), and a fill factor (FF) of 0.4. Although these values are low compared to current dye‐sensitized TiO2 solar cells, our findings could open up a promise for a stimulating research on the photovoltaic activity of zeolite‐based host–guest solids.
From necessity to responsibility: evidence for corporate environmental citizenship activities from a developing country perspective
Authors: Küskü Fatma 
Published: August 2006

AbstractThe objective of this study is to focus on corporate activities conducted to protect and preserve the environment, and to evaluate these activities with respect to social responsibility in a developing country setting. This study also tries to find out whether corporations take part in these activities due to social expectations and legal obligations or due to their own social awareness. The data was collected from Turkey, which is a good example of a developing country with its economic situation. Corporations from the automotive, pharmaceutical and textile industries were studied, as the products and the process of production of these industries pose a threat to the environment. The research findings show that in adopting environmental citizenship policies corporations are more influenced by ‘obligatory regulations’ coming from institutional forces than by ‘voluntary regulations’ coming from their own social awareness.

Homoepitaxial Growth on a 4H‐SiC C‐Face Substrate
Authors: Kojima K. , Kuroda S. , Okumura H. , Arai K. 
Published: August 2006

AbstractHomoepitaxial growth on a 4H‐SiC carbon face (C‐face) was investigated. The C‐face showed a similar site‐competition phenomenon to that seen on a 4H‐SiC Si‐face. This site‐competition phenomenon was distinctly sensitive to growth pressure. The surface morphology of the C‐face epitaxial layer was sensitive to surface imperfections on the substrate. The growth window of 4° off‐axis, C‐face substrates was shown to be wider than that of the corresponding Si‐face. A specular surface morphology without a bunched step structure was obtained over a whole 2 inch C‐face substrate with a vicinal off‐angle of 0.5°.
Reducing Planar Defects in 3C–SiC
Authors: Nagasawa H. , Yagi K. , Kawahara T. , Hatta N. 
Published: August 2006

AbstractThe planar defects that occur at the 3C–SiC/Si(001) interface can be classified as anti‐phase boundary (APB) and stacking‐fault (SF). In order to reduce SFs and APBs simultaneously, 3C–SiC is grown on undulant‐Si in which the surface is covered with continuous slopes oriented in the [110] and [$ \bar 1 \bar 1$0] directions. This eliminates APBs at each slope of an undulation via step‐flow epitaxy. In addition, SFs with an exposed C‐face on the (001) surface (SFC) are eliminated via self‐vanishing, while those with an exposed Si‐face on the (001) surface (SFSi) form triangular shapes that expand with increasing 3C–SiC thickness. To remove any SFSithat cannot be eliminated on the undulant Si, an advanced SF reduction method involving homoepitaxial growth, called switch‐back epitaxy (SBE), is investigated.
Thick Silicon Carbide Homoepitaxial Layers Grown by CVD Techniques
Authors: Henry A. , ul Hassan J. , Bergman J. P. , Hallin C. , Janzén E. 
Published: August 2006

AbstractThe growth of thick epitaxial SiC layers needed for high‐voltage, high‐power devices is described for two types (horizontal and vertical) of hot‐wall (HW) CVD reactors. In both cases, the advantages of HWCVD are the better cracking efficiency of the precursor gases and better temperature distribution together with low input power. Characterizations of some examples of thick SiC layers grown are given.
Thermodynamic Aspects of the Growth of SiC Single Crystals using the CF‐PVT Process
Authors: Chaussende D. , Blanquet E. , Baillet F. , Ucar M. , Chichignoud G. 
Published: August 2006

AbstractThe main trends that govern the continuous‐feed physical vapor transport (PVT), bulk‐crystal‐growth process is investigated experimentally, together with thermodynamic and computation fluid dynamics (CFD) calculations. Several chemical systems are considered. An analysis of the chemistry of every successive step (CVD, transfer, and PVT) is presented first. The effects of hydrogen and chlorine are then investigated. Then, the interaction between the different steps is discussed. The strong chemical interaction which exists between the CVD and the PVT zones is demonstrated to require the consideration of the whole process and not the two zones separately.
Growth of Silicon Carbide Bulk Crystals with a Modified Physical Vapor Transport Technique
Authors: Müller R. , Künecke U. , Queren D. , Sakwe S. A. , Wellmann P. 
Published: August 2006

AbstractIn this paper, the development of the modified physical vapor transport (M‐PVT) method for SiC bulk crystal growth is reviewed. For this technique, elements from CVD are combined with the conventional PVT (physical vapor transport) method to achieve a better process and particularly dopant control. To this end, an additional gas flow is introduced directly into the growth chamber of a PVT growth system. For stable crystal growth it is important that the additional gas flow is of the same order of magnitude as the SiC‐species flow by sublimation. Doping experiments resulted in phosphorous concentrations up to 1.5 × 1018 cm–3 and aluminum concentrations up to 1.3 × 1020 cm–3 using a PH3‐flow and a solid aluminum source in an external reservoir as dopant source, respectively. Also, the growth of a crystal with alternating p‐ and n‐type regions for the investigation of the charge carrier‐dependant dislocation evolution in SiC is presented to illustrate the outstanding flexibility that is offered by the M‐PVT method.
Prediction of radiosensitivity in human bladder cell lines using nuclear chromatin phenotype
Authors: Rajab Nor F. , McKenna Declan J. , Diamond Jim , Williamson Kate , Hamilton Peter W. , McKelvey‐Martin Valerie J. 
Published: August 2006

AbstractBackground:Nuclear texture analysis measures phenotypic changes in chromatin distribution within a cell nucleus, while the alkaline Comet assay is a sensitive method for measuring the extent of DNA breakage in individual cells. The authors aim to use both methods to provide information about the sensitivity of cells to ionizing radiation.Methods:The alkaline Comet assay was performed on six human bladder carcinoma cell lines and one human urothelial cell line exposed to γ‐radiation doses from 0 to 10 Gy. Nuclear chromatin texture analysis of 40 features was then performed in the same cell lines exposed to 0, 2, and 6 Gy to explore if nuclear phenotype was related to radiation sensitivity.Results:Comet assay results demonstrated that the cell lines exhibited different levels of radiosensitivity and could be divided into a radiosensitive and a radioresistant group at >6 Gy. Using stepwise discriminant analysis, a subset of important nuclear texture features that best discriminated between sensitive and resistant cell lines were identified A classification function, defined using these features, correctly classified 81.75% of all cells into their radiosensitive or radioresistant groups based on their pretreatment chromatin phenotype. Posttreatment chromatin changes also varied between cell lines, with sensitive cell lines showing a relaxed chromatin conformation following radiation, whereas resistant cell lines exhibited chromatin condensation.Conclusions:The authors conclude that the alkaline Comet assay and nuclear texture methodologies may prove to be valuable aids in predicting the response of tumor cells to radiotherapy. © 2006 International Society for Analytical Cytology
Retransmission strategies for an acceptable quality of HDTV in the wireless and wired home scenario
Authors: Vanhaverbeke Frederik , Moeneclaey Marc , Vleeschauwer Danny De 
Published: August 2006

AbstractWe evaluate the performance of various retransmission schemes to achieve the goal of less than one visible distortion in twelve hours for high definition television. The focus is on an indoor wireless link and a DSL link, and we consider systems where the packets are protected by means of retransmissions with and without forward error correcting (FEC) codes. In order to achieve a satisfactory performance with restricted latency, we propose an unconventional retransmission procedure. The overall conclusion is that retransmissions without FEC achieve the best performance with the lowest latency, lowest overhead and lowest complexity, both in the wireless and the wired home scenario.
