Authors: Murry Thomas , Branski Ryan C. , Yu Kathy , Cukier‐Blaj Sabrina , Duflo Suzy , Aviv Jonathan E. 
Published: June 2010

AbstractObjectives/Hypothesis:Although the diagnostic accuracy of paradoxical vocal fold movement disorder and chronic cough has improved, the underlying pathophysiology remains relatively unknown. We hypothesize that one potential etiological factor in these patients is an aberrant laryngeal sensory response and sought to determine if respiratory retraining in addition to antireflux therapy alters this aberrant response.Study Design:Retrospective, outcomes.Methods:Sixteen patients who had been on at least 3 months of twice‐daily proton pump inhibitors with no subjective improvement in their primary complaint of cough, self‐reported symptoms of gastroesophageal and laryngopharyngeal reflux, and concurrent paradoxical vocal fold movement (PVFM) were included in the current study. In addition to continuing twice daily pharmacological therapy, subjects underwent a course of respiratory retraining. Outcome measures including the Reflux Symptom Index (RSI), transnasal flexible laryngoscopy, and laryngopharyngeal sensory discrimination thresholds were obtained prior to and following a course of respiratory retraining.Results:Mean bilateral laryngeal sensory response improved significantly after combined respiratory retraining and aggressive proton pump inhibitor therapy (P = .01). In addition, mean RSI score decreased significantly following treatment (P = .02). Specifically, 13 of 16 patients experienced improved sensory response, corresponding with patient reports of improved PVFM symptoms following treatment.Conclusions:Aberrant laryngeal sensation was identified in patients with PVFM and chronic cough. This response, however, normalized following a limited course of respiratory retraining, corresponding with improved patient symptoms. Laryngoscope, 2010

AbstractThe effects of zinc oxide and/or polyethylene glycol (PEG) as electrolyte additives on the corrosion and electrochemical performances of pure aluminum in 4.0 M KOH solutions were investigated by means of hydrogen collection, polarization curve, galvanostatic discharge, scanning electron microscopy (SEM), and energy dispersive analysis of X‐ray (EDAX). The addition of ZnO markedly inhibited the corrosion of aluminum in 4.0 M KOH solutions, resulting from the deposition of zinc with high hydrogen evolution overpotential in aluminum surfaces. The introduction of PEG in the alkaline zincate solution obviously improved the deposition of zinc by increase in the overpotential of zinc deposition, thus the corrosion rate of aluminum in the alkaline zincate solutions with PEG was further decreased. The enhancement effect of PEG on the inhibition of zinc oxide first increased and then decreased with increasing the content of PEG in the electrolyte. The electrolyte system with 0.2 M ZnO and 2.0 mM PEG presented the highest inhibition efficiency (98.8%) for the corrosion of aluminum. The results of galvanostatic discharge indicated that the aluminum anode shows excellent discharge performances in the 4.0 M KOH solution with 0.2 M ZnO and 2.0 mM PEG.
Preparation of Polybenzimidazole/Lithium Hydrazinium Sulfate Composite Membranes for High‐Temperature Fuel Cell Applications
Authors: Jung Jung‐Woo , Kim Sung‐Kon , Lee Jong‐Chan 
Published: June 2010

AbstractPBI‐LiHzS composite membranes were prepared by casting N,N'‐DMAc solutions containing PBI and LiHzS, where the LiHzS contents in the membranes were between 2.5 and 10 wt.‐%. LiHzS was obtained by reacting hydrazine sulfate and lithium carbonate in water. PBI‐LiHzS composite membranes were thermally stable up to approximately 300 °C and their acid‐absorbing capabilities were comparable to those of the pure PBI membranes. The proton conductivity of PBI‐LiHzS composite membranes (2.12 × 10−2 S · cm−1 at 180 °C and 0% RH) was higher than that of pure PBI membranes when used at the same acid doping levels. The mechanical stability of the composite membranes having less than 5 wt.‐% of LiHzS was found to be close to that of pure PBI membranes.magnified image
The differential roles of brand credibility and brand prestige in consumer brand choice
Authors: Baek Tae Hyun , Kim Jooyoung , Yu Jay Hyunjae 
Published: June 2010

AbstractThis study explores how brand credibility and brand prestige affect brand purchase intention and empirically investigates how the combinatory mechanism of brand credibility and brand prestige materialize across multiple product categories. The proposed model of six latent constructs is tested with structural equation modeling analysis: brand credibility, brand prestige, perceived quality, information costs saved, perceived risk, and brand purchase intention. The results suggest that both brand credibility and brand prestige positively influence brand purchase intention through perceived quality, information costs saved, and perceived risk under different product categories representing the high and low self‐expressive nature. Several implications for advertising messages and brand positioning strategies are discussed. © 2010 Wiley Periodicals, Inc.
Measuring childhood materialism: Refining and validating Schor's Consumer Involvement Scale
Authors: Bottomley Paul A. , Nairn Agnes , Kasser Tim , Ferguson Yuna L. , Ormrod Johanne 
Published: June 2010

AbstractThis paper examines the measurement of childhood materialism using Schor's (2004) Consumer Involvement Scale. Schor treated consumer involvement empirically as a unidimensional construct, though she suggested that conceptually it may be multidimensional. Using confirmatory factor analysis procedures on data collected from children in the U.S. and U.K., the psychometric superiority of a three‐factor structure is established, comprising dissatisfaction, consumer orientation, and brand awareness components. Additional analyses demonstrate distinct associations between each of these components and other constructs, including self‐esteem, outside school activities, and child–parent relations. The scale's generalizability across boys and girls is also confirmed. The results suggest that Schor's Consumer Involvement Scale will be useful for researchers interested in studying the important topic of materialism in children. © 2010 Wiley Periodicals, Inc.
UWB printed monopole antenna with embedded reconfigurable multiband filter based on miniaturized ground plane slot
Authors: Khidre Ahmed , Rahman Adel Abdel , Elsadek Hala , Omar Abbas , Ragai Hani 
Published: June 2010

AbstractUWB printed monopole antenna with embedded reconfigurable multiband frequency notch function is proposed. Frequency notch is achieved by using a ground‐plane slot. Lumped capacitors are added to miniaturize the slots and hence take advantages of adding more slots to reject more bands without increasing the overall size of the antenna. Added capacitors are also enhancing band rejection and introduce tunable capability. Reconfigurabiltiy is introduced in a way you can independently switch ON/OFF the band notches by mean of RF switches. Investigation on the effect of lumped capacitor is presented. Simulation results of S11 for different states and radiation patterns at different frequencies are also presented. Simulation results are verified with measurements. The commercial CST Microwave Studio 5 is used for simulations and performance optimizations. © 2010 Wiley Periodicals, Inc.

Published: June 2010

AbstractA simple all‐optical add‐drop multiplexer scheme is presented by utilizing cross gain modulation (XGM) and four‐wave mixing (FWM) effects in a single semiconductor optical amplifier (SOA). When the synchronized data stream and control signal is launched into a SOA, FWM generates the dropped channel, while XGM is used to clean the corresponding bit slots for adding new data. This function is demonstrated at 10 Gbit/s by simulation and experiment. Both of them show good performance. © 2010 Wiley Periodicals, Inc.

Published: June 2010

AbstractWe report on a single‐longitudinal‐mode single‐wavelength fiber laser and its applications for measuring localized temperature variation. The laser was developed using a fiber Bragg grating. The laser wavelength was single‐longitudinal‐mode with optical signal‐to‐noise ratio (OSNR) of more than 40 dB. The temperature sensitivity of the system was 11.08 pm/°C. To demonstrate the promising application of the laser sensor developed, we used the sensor to monitor the localized temperature of TiO2 nanotubes during the photochemical process, and superparamagnetic iron oxides nanoparticles when exposed to low frequency magnetic field. The output of the laser was monitored using a scanning Fabry–Perot spectrum analyzer of resolution 6.7 MHz and an optical spectrum analyzer of resolution 3.75 GHz. © 2010 Wiley Periodicals, Inc.

A novel reconfigurable microstrip antenna with polarization diversity
Authors: Sung Y. 
Published: June 2010

AbstractIn this letter, a novel reconfigurable microstrip antenna with polarization diversity is proposed.The proposed antenna has a simple structure, consisting of a corner‐truncated square radiating patch, two small triangular conductors, and a microstrip line feed. The proposed antenna can produce left hand circular polarization or right hand circular polarization according to the on‐ or off‐state of PIN diode, which is between radiating patch and parasitic triangular conductor. Comparing with a conventional antenna, the proposed antenna may obtain a size reduction of the antenna system and a low‐consumption current because the required PIN diode is reduced by half. Measured results show that symmetrical radiation patterns with good CP characteristics are obtained at the resonant frequency. © 2010 Wiley Periodicals, Inc.

AbstractTo investigate compact shape bandpass filter, a second‐order microstrip with three controllable finite transmission zero points is proposed in this article. The U‐shape slots are designed to suppress spurious band, and controllable stopband characteristics can be achieved simultaneously, as well as skirt selectivity. The simulated results agree very well with measurements. When compared with other similar structure, the proposed filter is much more efficient than other counterpart. © 2010 Wiley Periodicals, Inc.

Size‐reduced defected ground microstrip directional coupler
Authors: Mohra Ashraf S. , Alkanhal Majeed A. , Abdullah Esmat A. 
Published: June 2010

AbstractIn this article, size reduction and harmonic suppression in coupled‐lines microstrip directional couplers is attained using dumbbell, and reshaped dumbbell slots, as defected patterns, specifically placed under the metering position in the ground plane. Quantitative investigation of the performance of the directional coupler as controlled by the variations of the DGS rectangular slots height, DGS gap length, and the DGS reshaped rectangular slot height is presented. This concept is further illustrated experimentally for a 12 dB coupler realized on RT/Duroid 5880 substrate. The proposed DGS design confers size reduction because of the shift of the operating frequency to lower values. The measurements are in a good agreement with the simulated results and emphasize the size reduction and the harmonics suppression of the DGS coupled‐lines microstrip directional coupler. © 2010 Wiley Periodicals, Inc.

Design of compact, narrow‐band, band‐pass microwave filters in coplanar waveguide technology
Authors: Behdad Nader 
Published: June 2010

AbstractA new topology for designing compact, band‐pass filters of arbitrary order is proposed. The basic building block of band‐pass filters designed using this technique is a capacitively coupled second‐order filter, which can be thought of as the unit cell of a higher order band‐pass filter. The second‐order filter is composed of slow‐wave transmission line resonators separated by an inductive admittance inverter. To easily control the bandwidth of the filter, the entire structure is capacitively coupled to the feeding transmission lines using series capacitors. This unit cell can be used in different cascading schemes to obtain filters of odd and even orders. Using this technique, band‐pass filters with fractional bandwidths in the range of 1–20% can easily be designed. Several different examples of such band‐pass filters along with their measurement results are presented and discussed in this article. © 2010 Wiley Periodicals, Inc.

Enabling international communication among Brazilian occupational therapists: seeking consensus on occupational terminology
Authors: Magalhaes Lilian , Galheigo Sandra Maria 
Published: June 2010

AbstractThe purpose of this study was to examine how key occupational therapy terminologies are used by Brazilian occupational therapists. A nominal group approach combined with a Delphi technique involving 31 Brazilian occupational therapists was applied. A sociolinguistic approach was adopted since it broadens our understanding of the social and cultural determinants of terminology consolidation. Brazilian occupational therapists were found to adopt the term activity more often than human action or doing. Even less often were praxis and occupation applied. No consensus was reached regarding which of the terms is most preferred.While Brazilian occupational therapists have been developing their profession from international standards, it is still embedded in local demands and policies. Additionally, the political context must be considered when building an international dialogue between members of a professional body. Such a dialogue could engage professionals from different countries in meaningful exchanges about their practices. These exchanges may lead to the development of solid professional communities that can contribute meaningfully to social change. Copyright © 2010 John Wiley & Sons, Ltd.
Effects of multiwalled carbon nanotube on holographic polymer dispersed liquid crystal
Authors: Sun Ka Ram , Kim Byung Kyu 
Published: June 2010

AbstractThe morphology and electro‐optical performance of holographic polymer dispersed liquid crystal (HPDLC) were investigated with the addition of multiwalled carbon nanotube (CNT), both pristine and chemically modified one (CNT‐CC). With the addition of CNT, the diffraction efficiency increased and showed a maximum at 0.6% while nucleation was delayed due to the increased mixture viscosity. Film was driven only with CNT due to the induced local electric field of polymer to overcome the threshold resistance. Among the two types of CNT, chemically modified one gave finer CNT dispersion, lower mixture viscosity, larger liquid crystal (LC) droplet, higher diffraction efficiency, and shorter response time while the pristine CNT decreased the driving voltage.
