A Model to Predict Granular Activated Carbon Backwash Curves
Authors: Dabrowski Wojciech , Spaczyńska Marta , Mackie R. Ian 
Published: January 2008

AbstractA mathematical model that produces curves for predicting the expansion of granular activated carbon (GAC) filter beds has been developed and applied to several widely used commercial GAC products. Initially, the hydraulic load required to produce a given bed expansion was assumed to be inversely proportional to the viscosity. This assumption was then modified by assuming a power law for the dependence on viscosity. The errors were sufficiently small to allow practical application of the formulae presented in this paper. The potential for application of the method was tested and is illustrated by an example.
Electro‐Catalytic Degradation of Phenol Organics with SnO2‐Sb2O3/Ti Electrodes
Authors: Zhu Kaijin , Zhang Wencai , Wang Huifang , Xiao Zhongliang 
Published: January 2008

AbstractThe effect of extraordinary degradation of phenol organics on the SnO2‐Sb2O3/Ti electrode is investigated through experimental research and theoretical analysis. The phenol organics contained 4‐chloro‐phenol, 4‐bromo‐phenol, and 2‐iodo‐phenol. At a current density of 4 mA cm–2 and an electrolysis time of 12 h, the degradation efficiency of the phenols was over 98% with a relatively short degradation time, whereas the degradation time of the PbO2/Ti electrode surpassed 40 h while delivering 100% disposal efficiency. Therefore, the effectiveness of electrochemical (EC) oxidation by the SnO2‐Sb2O3/Ti was superior to that of the PbO2/Ti electrode. At the same time, the SnO2‐Sb2O3/Ti had higher oxygen generation potential and lower electron consumption than the other electrodes. This was mainly due to the effect of the middle Sb2O3 layer, which due to its high porosity and good catalytic effect, contributed to a better catalysis than the SnO2 part.
Family history and survival after colorectal cancer diagnosis

Published: January 2008

AbstractBACKGROUNDA history of colorectal cancer in a first‐degree relative is a recognized risk factor for developing this malignancy. The influence of a family history of colorectal cancer on survival after a diagnosis of colorectal cancer was examined in a large cohort of women.METHODSWe analyzed data from 1001 women diagnosed with colorectal cancer while participating in a prospective cohort study. Data on family history were obtained before cancer diagnosis. We computed Cox proportional hazards for cancer‐specific and overall mortality according to a family history of colorectal cancer, adjusting for other predictors for survival.RESULTSBefore diagnosis, 16% of colorectal patients reported a history of colorectal cancer in a first‐degree relative. Patients with a history of colorectal cancer in 1 or more first‐degree relatives experienced an adjusted hazard ratio (HR) for overall mortality of 1.32 (95% confidence interval [CI], 1.01–1.72) and colorectal cancer‐specific mortality of 1.38 (95% CI, 1.02–1.86) when compared with those without a family history. Moreover, patients with 2 or more affected relatives had an HR for overall mortality of 2.07 (95% CI, 1.14–3.76) and cancer‐specific mortality of 2.19 (95% CI, 1.10–4.38). The significant deleterious effect of family history was limited to patients with advanced disease at presentation and cancers originating in the colon.CONCLUSIONSAmong women with colorectal cancer, a history of colorectal cancer in a first‐degree relative was associated with a significant decrease in survival. Additional study is needed to validate these findings and determine whether specific germline polymorphisms correlate with clinical outcomes. Cancer 2008. © 2008 American Cancer Society.
Neuroblast proliferation on the surface of the adult rat striatal wall after focal ependymal loss by intracerebroventricular injection of neuraminidase

Published: January 2008

AbstractThe subventricular zone of the striatal wall of adult rodents is an active neurogenic region for life. Cubic multiciliated ependyma separates the subventricular zone from the cerebrospinal fluid (CSF) and is involved in the control of adult neurogenesis. By injecting neuraminidase from Clostridium perfringens into the right lateral ventricle of the rat, we provoked a partial detachment of the ependyma in the striatal wall. The contralateral ventricle was never affected and was used as the experimental control. Neuraminidase caused widening of the intercellular spaces among some ependymal cells and their subsequent detachment and disintegration in the CSF. Partial ependymal denudation was followed by infiltration of the CSF with macrophages and neutrophils from the local choroid plexus, which ependymal cells never detached after neuraminidase administration. Inflammation extended toward the periventricular parenchyma. The ependymal cells that did not detach and remained in the ventricle wall never proliferated. The lost ependyma was never recovered, and ependymal cells never behaved as neural stem cells. Instead, a scar formed by overlapping astrocytic processes sealed those regions devoid of ependyma. Some ependymal cells at the border of the denudated areas lost contact with the ventricle and became located under the glial layer. Concomitantly with scar formation, some subependymal cells protruded toward the ventricle through the ependymal breaks, proliferated, and formed clusters of rounded ventricular cells that expressed the phenotype of neuroblasts. Ventricular clusters of neuroblasts remained in the ventricle up to 90 days after injection. In the subventricular zone, adult neurogenesis persisted. J. Comp.

Phase‐field model for deposition of pyrolytic carbon
Authors: Ekhlakov A. , Dimitrov S. , Langhoff T.‐A. , Schnack E. 
Published: January 2008

AbstractA diffuse interface model for the determination of the evolution of the deposited substrate surface during isobaric, isothermal chemical vapour infiltration (CVI) of pyrolytic carbon is proposed. A continuous scalar phase‐field parameter is introduced to label explicitly the solid and the gas phases within the system. Following the conceptual line of Ginzburg–Landau theory, we formulate the initial boundary value problem of CVI. In variance with the traditional formulations, we account for the different intensities of homogeneous and heterogeneous chemical reactions during CVI by introducing a scalar‐valued intensity parameter that depends only on the phase‐field. The various homogeneous and heterogeneous reaction processes during CVI are described in terms of a reduced chemical reaction scheme. Finally, we discuss the application of the developed methodology for numerical simulation of a simplified two‐dimensional model problem. Using a finite element method, we obtain numerical approximations for the concentration profiles along the direction of infiltration. Copyright © 2008 John Wiley & Sons, Ltd.
The effects of variable fluid properties and magnetic field on the flow of non‐Newtonian fluid film on an unsteady stretching sheet through a porous medium
Authors: Elgazery Nasser S. , Hassan M. A. 
Published: January 2008

AbstractThe effects of variable viscosity, variable thermal diffusivity and magnetic field on the flow and heat transfer in a laminar liquid film of non‐Newtonian fluid on a horizontal stretching sheet through a porous medium are analyzed. Using a similarity transformation, the governing time‐dependent boundary‐layer equations for momentum and thermal energy are reduced to a set of coupled nonlinear ordinary differential equations. The resulting seven‐parameter problem is solved numerically by using Chebyshev pseudospectral method for some representative value of the parameters. The numerical results show that variable viscosity, variable thermal diffusivity, the upper limit of apparent viscosity according to biviscosity model, the unsteadiness parameter, the magnetic parameter, and the permeability parameter have significant influences on the velocity and temperature profiles, shear stress, and Nusselt number.It is observed that the presence as well as the increase in the unsteadiness parameter S, variable viscosity parameter β1, the upper limit of apparent viscosity β, and the magnetic parameter M lead to decrease in the fluid film thickness η∞. Also, as film thickness approaches zero as S comes close to the critical value; then, there is no available solution for the problem. The velocity profiles supported this result, since close to this critical value the velocity of the fluid vanishes. Copyright © 2008 John Wiley & Sons, Ltd.
An efficient admission control for IEEE 802.11 networks based on throughput analyses of (un)saturated channel
Authors: Lin Lidong , Fu Haohuan , Jia Weijia 
Published: January 2008

AbstractThis paper presents a novel analytical model and an efficient admission control (AC) algorithm for IEEE 802.11 distributed coordinated function access mechanism. In contrast to the previous approaches, both saturated and unsaturated states of network are analyzed and the impacts of error‐frame rate and retransmission limit are also taken into account based on an improved Markov chain model. Thus, the network resources can be efficiently utilized. Taking the throughput difference between saturated and unsaturated states as the residual bandwidth, an efficient AC algorithm is designed to utilize the network resources effectively. Extensive simulation data match our analytical results and demonstrate that the AC algorithm is efficient and can make the effective utilization of network resources.

Estimation of charge distribution on a bulky solid dielectric using regularization technique
Authors: Tatematsu Akiyoshi , Hamada Shoji , Takuma Tadasu 
Published: January 2008

AbstractWe have been studying a multi‐point charge measurement method using an electrostatic probe. In this technique, charge densitiesxmust be estimated from the probe outputsbby an inverse calculation based on an equationAx=b. The matrixAis obtained by applying a numerical field calculation technique. When the matrixAis in ill‐condition, the solution often makes no sense, including extremely large errors. Therefore, we apply the regularized least squares method (RLS) with a penalty term to perform the inverse calculation stably for the ill‐conditioned matrix. The penalty term imposes some constraints on the solutions. In this paper, first, we have analyzed the accuracy of the charge distribution estimated by the inverse calculation. Although the perturbation bound of the solution errors has already been proposed for the least squares method, it has not yet been given for the RLS. We have derived the equations that express the perturbation bound of the solution errors in applying the RLS to evaluate the estimation accuracy. Second, we have applied the above equations to an experimental result for a cylindrical dielectric solid, and estimated the charge distribution represented by 10,140 unknowns. We have utilized an iteration technique and the symmetric configuration of the measured arrangement so as to reduce the amount of operations and memory capacity required for the inverse calculation. © 2008 Wiley Periodicals, Inc.

Generation of pseudo‐random numbers by chaos‐type function and its application to cryptosystems
Authors: Toyama Junichiro , Kawamoto Shunji 
Published: January 2008

AbstractThe logistic map is known to be one of the nonlinear difference equations as a chaos map, and to generate pseudo‐random numbers. However, since the chaos has a highly sensitive dependence on initial conditions and accumulates inevitable round‐off errors caused by iterating the map, the numerical generation of exact chaotic time series is said to be impossible. The aim of this paper is, first, to propose an algorithm to generate exact chaotic time series of a chaos‐type function derived from the exact chaos solution. Next, the pseudo‐random numbers are evaluated by four tests and the accumulation of chi‐square values. Also, an application to cryptosystems, which do not need the synchronization in usual computer environments, is considered. © 2008 Wiley Periodicals, Inc.

Published: January 2008

AbstractRenewable forms of energy such as wind power or photovoltaic energy are environmentally focused, but the fluctuation of the output power of such renewable forms of energy may cause excessive variation of the voltage or frequency of the grid. Increasing the amount of renewable energy would degrade the quality of the grid. Micro grids, in which dispersed power sources compensate variations in the generation of renewable energy, can expand the limits of installation of renewable forms of energy by maintaining the quality of the interconnected grid. This paper discusses the use of gas turbines to absorb power variations from wind generation and the loads. In order to control the output power, gas turbines must run under partial load, which results in lower efficiency. An evaluation of the micro grids is made with consideration of their efficiency, the installed capacity of wind power generation systems, and frequency stability for islanded operation. © 2008 Wiley Periodicals, Inc.

A bidirectional isolated DC/DC converter as a core circuit for 3.3‐kV/6.6‐kV power conversion systems in the next generation
Authors: Inoue Shigenori , Akagi Hirofumi 
Published: January 2008

AbstractThis paper describes a bidirectional isolated DC/DC converter considered as a core circuit for next‐generation 3.3‐kV/6.6‐kV high‐power‐density power conversion systems. The DC/DC converter is intended to use power switching devices based on SiC and/or GaN, which will be available on the market in the near future. A 350‐V, 10‐kW, and 20‐kHz DC/DC converter is designed, constructed, and tested in this paper. It consists of two single‐phase full‐bridge converters with the latest trench‐gate Si‐IGBTs and a 20‐kHz transformer with a nano‐crystalline soft‐magnetic material core and litz wires. The transformer plays an essential role in achieving galvanic isolation between the two full‐bridge converters. The overall efficiency from the DC‐input to DC‐output terminals is accurately measured to be as high as 97%, excluding gate drive circuit and control circuit losses from the whole loss. Moreover, loss analysis is carried out to estimate effectiveness in using SiC‐based power switching devices. The loss analysis clarifies that the use of SiC‐based power devices may bring a significant reduction in conducting and switching losses to the DC/DC converter. As a result, the overall efficiency may reach 99% or higher. © 2008 Wiley Periodicals, Inc. Electr Eng Jpn, 163(2): 75–83, 2008; Published online in Wiley InterScience (www.interscience.wiley.com).

Published: January 2008

AbstractWe propose an improvement of an information filtering process with independent components selection. The independent components are obtained by Independent Components Analysis and considered as topics. Selection of independent components is an efficient method of improving the accuracy of the information filtering for the purpose of extraction of similar topics by focusing on their meanings. To achieve this, we select the topics by Maximum Distance Algorithm with Jensen‐Shannon divergence. In addition, document vectors are represented by the selected topics. We create a user profile from transformed data with a relevance feedback. Finally, we sort documents by the user profile and evaluate the accuracy by imputation precision. We carried out an evaluation experiment to confirm the validity of the proposed method considering meanings of components used in this experiment. © 2008 Wiley Periodicals, Inc.

Structural and Magnetic Properties of Two Copper(II) Complexes Based on Dinuclear Copper(II) Metallacyclophane
Authors: Qu Xiaoni , Song Xueyan , Li Wei , Xu Yunhe , Li Licun , Liao Daizheng , Jiang Zonghui 
Published: January 2008

AbstractTwo new oxamato‐bridged copper(II) complexes of formula Na10[{Cu2(mpba)2}2(μ1,1‐N3)2]·18H2O (1) and [{Cu2(mpba)2}Cu2(H2O)8]·6H2O (2) [mpba = 1,3‐phenylenebis(oxamato‐N,N′)] have been synthesized and characterized. X‐ray crystallographic studies of complex 1 reveal a metallamacrocycle structure in which two dinuclear copper(II) metallacyclophane anions are linked by two single symmetric azido ligands in an end‐on mode at axial–axial positions. These metallamacrocycle units are self‐assembled through sodium cations and water molecules, affording an intricate 3D network. Complex 2 consists of 2D brick‐wall‐like layers assembled from dinuclear metallacyclophane [Cu2(mpba)2]4– anions and copper(II) cations. Magnetic susceptibility measurements of complex 1 in the temperature range 2–300 K show dominating ferromagnetic coupling mediated by the m‐phenylenediamide bridge and weak antiferromagnetic interaction transmitted by the azido ligand.(© Wiley‐VCH Verlag GmbH & Co.
