Simple Printed WWAN Monopole Slot Antenna with Parasitic Shorted Strips for Slim Mobile Phone Application
Authors: Chang Chih‐Hua , Wei Wan‐Chu , Ma Pei‐Ji , Huang Shao‐Yu 
Published: October 2015

ABSTRACTIn this article, a simple printed monopole slot antenna with two parasitic shorted strips (a longer parasitic shorted strip and a shorter parasitic shorted strip) for penta‐band wireless wide area network operation in the slim mobile phone is presented. The monopole slot has a length of 40 mm only and is disposed near the bottom edge of the system ground plane of the mobile phone with a small distance of 6.5 mm. By adding longer parasitic shorted strip connected to the bottom corner edge of the system ground plane, good excitation of the monopole slot antenna at its fundamental (quarter‐wavelength) mode and chassis dipole‐type mode of the system ground plane can be obtained. The shorter parasitic shorted strip contributes additional resonant mode to the antenna. The excited resonant modes form two wide operating bands to cover the GSM850/900 operation (824–960 MHz) and GSM1800/1900/WCDMA Band I operation (1710–2170 MHz), respectively. Details of the proposed antenna are presented. The specific absorption rate results for the antenna with the presence of the head and hand phantoms are also studied. © 2013 Wiley Periodicals, Inc.

Published: October 2015

ABSTRACTThis article presents a method to extract the elements of the electrical equivalent circuit model CMOS pads using two uniform transmission lines fabricated on a lossy Si substrate. The lengths of the uniform transmission lines are different, while its characteristic impedances are equal and can be of an arbitrary value. The proposed method is useful for modeling CMOS pads that can be represented by symmetrical and reciprocal ABCD matrices, denoted as [Mpad]. Then a T‐network is used to represent the CMOS pad and its elements are determined converting [Mpad] into a Z‐parameters matrix. Experimental data from 0.4–20 GHz show a high correlation with theoretical data. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:3033–3037, 2013
Design Construction and Testing of a Compact Size Patch Antenna for RFID Applications
Authors: Islam S. , Latrach M. 
Published: October 2015

ABSTRACTThis article presents the miniaturization techniques of multilayers patch antennas in the UHF frequency band for RFID applications. By embedding suitable slots in a radiating patch, enhanced impedance bandwidth can be obtained with compact size antenna. In this study, first a patch on multilayer substrate will be presented and then its miniaturized form will be presented. The miniaturized form is obtained by etching two long slots on both size of the feeding line and also two other rectangular slots at the radiation edge of the patch. Simulation and experimental results indicate that a size reduction of up to 30% is possible by using the technique. The simulation gain of the first antenna is 8.32 dB, whereas the gain of the compact antenna is 7.68 dB. The measurement results agree very well with the simulation results. The impedance bandwidth of the antennas before and after the miniaturization remains almost unchanged. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2920–2925, 2013

A New Narrow Band Frequency Selective Surface Geometry Design at the Unlicensed 2.4‐GHz ISM Band
Authors: Kartal Mesut , Pinar Sedef Kent , Doken Bora , Gungor Ismail 
Published: October 2015

ABSTRACTWireless devices in the unlicensed instruments, scientific, and measurements (ISM) bands cause mutual interference in indoor environments. This interference degrades the system performance and compromises security. Transforming existing building walls to a band stop frequency selective surface (FSS) can be an efficient solution for such problems. This work is proposed to design FSS for interference mitigation and network security within the buildings in the unlicensed 2.4‐GHz ISM band and to provide maximum transparency at broadcast frequencies. A 2.4‐GHz ISM band is a relatively narrow band which cannot be met by a conventional FSS for a wide range of incidence angle. Whereas wireless signals in indoor environment have a wide range of incidence angle. To obtain the desired narrow band response, a new FSSs element geometry is introduced which has a stable frequency response for TE polarization when the angle of incident wave is varied from 0° to 70°. HFSS software is used for simulation and design purposes. The obtained simulation and measurement results show that desired frequency response is achieved for TE polarization successfully. © 2013 Wiley Periodicals, Inc.

Weak forms for modelling of rotationally symmetric, multilayered structures, including anisotropic poro‐elastic media
Authors: Östberg M. , Göransson P. , Hörlin N‐E. , Kari L. 
Published: October 2015

SUMMARYA weak form of the anisotropic Biot's equation represented in a cylindrical coordinate system using a spatial Fourier expansion in the circumferential direction is presented. The original three dimensional Cartesian anisotropic weak formulation is rewritten in an arbitrary orthogonal curvilinear basis. Introducing a cylindrical coordinate system and expanding the circumferential wave propagation in terms of orthogonal harmonic functions, the original, geometrically rotationally symmetric three dimensional boundary value problem, is decomposed into independent two‐dimensional problems, one for each harmonic function. Using a minimum number of dependent variables, pore pressure and frame displacement, a computationally efficient procedure for vibro‐acoustic finite element modelling of rotationally symmetric three‐dimensional multilayered structures including anisotropic porous elastic materials is thus obtained. By numerical simulations, this method is compared with, and the correctness is verified against, a full three‐dimensional Cartesian coordinate system finite element model.

Plant growth‐promoting rhizobacteria (PGPR) facilitate the plant growth and enhance their induced systemic resistance (ISR) against a variety of environmental stresses. In this study, we carried out integrative analyses on the proteome, transcriptome, and metabolome to investigate Arabidopsis root and shoot responses to the well‐known PGPR strain Paenibacillus polymyxa (P. polymyxa) E681. Shoot fresh and root dry weights were increased, whereas root length was decreased by treatment with P. polymyxa E681. 2DE approach in conjunction with MALDI‐TOF/TOF analysis revealed a total of 41 (17 spots in root, 24 spots in shoot) that were differentially expressed in response to P. polymyxa E681. Biological process‐ and molecular function‐based bioinformatics analysis resulted in their classification into seven different protein groups. Of these, 36 proteins including amino acid metabolism, antioxidant, defense and stress response, photosynthesis, and plant hormone‐related proteins were up‐regulated, whereas five proteins including three carbohydrate metabolism‐ and one amino acid metabolism‐related, and one unknown protein were down‐regulated, respectively. A good correlation was observed between protein and transcript abundances for the 12 differentially expressed proteins during interactions as determined by qPCR analysis. Metabolite analysis using LC‐MS/MS revealed highly increased levels of tryptophan, indole‐3‐acetonitrile (IAN), indole‐3‐acetic acid (IAA), and camalexin in the treated plants. Arabidopsis plant inoculated P. polymyxa E681 also showed resistance to Botrytis cinerea infection. Taken together these results suggest that P. polymyxa E681 may promote plant growth by induced metabolism and activation of defense‐related proteins against fungal pathogen.
Synthesis and characterization of physically crosslinked N‐vinylcaprolactam, acrylic acid, methacrylic acid, and N,N‐dimethylacrylamide hydrogels

Published: October 2015

ABSTRACTPhysically crosslinked hydrogels based on N‐vinylcaprolactam/acrylic acid and N‐vinylcaprolactam/methacrylic acid were prepared via free radical polymerization. These temperature responsive hydrogels were characterized in terms of glass transition, phase separation temperature, potentiometric titration and swelling properties. Results showed that phase transition temperature was dependent on the pH value of the solution; increasing pH led to higher lower critical solution temperature (LCST) values which was related to the dissociative behaviors of the carboxylic group of MAc in the buffered solutions. Additionally, with the incorporation of N,N‐dimethylacrylamide into the system, cloud point measurements and MDSC showed an increased in the LCST. This increase was based on hydrophilicity, the hydrophilic–hydrophobic balance was disturbed, and consequently, the LCST behavior was shifted. The pKa of the copolymers ranged between 5.6 and 6.5, while for the terpolymers pKa ranged between 5.3 and 6. At high pH (>10), the COOH group is deprotonated and negatively charged (COO−), while at low pH (1–3) the carboxylic group remains protonated which results in hydrogen bonding between the hydroxyl groups (from NaOH) and the excess of HCl. These results correlate with swelling studies where above the pKa value the hydrogels dissolved rapidly compared to below pKa they did not dissolve at all. © 2013 Wiley Periodicals, Inc. J. Polym.

Reinforcing the role of psycho‐social oncology in global cancer prevention: applying psycho‐oncology research in programmes and practice
Authors: Dunn Jeff , Adams Cary , Holland Jimmie , Watson Maggie 
Published: October 2015

AbstractOver the past decade, global action to address the emerging crisis in non‐communicable diseases (NCDs) has escalated. Central to these efforts has been the support and influence of the World Health Organisation and the United Nations with the 2000 civil societies represented by the Non‐Communicable Disease Alliance. In particular this reached expression in the world's first High Level Meeting on NCDs by the United Nations leading to the 2011 Political Declaration urging a coordinated global response to NCDs.Where then does psycho‐oncology sit in this global context? Psycho‐oncology practitioners and their collective, the International Psycho‐Oncology Society (IPOS), have traditionally been situated within a patient focus and context. However, through linkages with community‐based and non‐government cancer organisations' agencies, psycho‐oncology research and practice has played a key role in reducing cancer risk, improving cancer survivorship, and influencing social and cultural change to eliminate disease‐related stigma. As a discipline, psycho‐oncology has contributed to widespread recognition of patient‐centred care in cancer and along with a broad acceptance and endorsement of the IPOS International Standard. However psycho‐oncology is less well accepted in nation‐state cancer plans and herein lies opportunity.This special issue includes research across the illness continuum from cancer prevention to screening and early detection, and then to tertiary prevention with lifestyle considerations for cancer survivors. Importantly this demonstrates the capacity within psycho‐oncology to develop new understandings of cancer as not only a disease but also a context linked to individual, community, and society health and well‐being.

Spectral Investigation and Color Properties of Copper(I) Halides CuX (X=F, Cl, Br, I) in Pyrotechnic Combustion Flames
Authors: Koch Ernst‐Christian 
Published: October 2015

AbstractFour pyrotechnic compositions containing copper or its compounds and different halogens were tailored to produce the emitters copper(I) fluoride, CuF, copper(I) chloride, CuCl, copper(I) bromide, CuBr, and copper(I) iodide, CuI. The UV/Vis emission spectra of these compositions were measured and allow for the identification and assignment of the above species CuF, CuCl, CuBr, and CuI. Copper(I) fluoride is a poor emitter with a very narrow green band centered at λ=493 nm only. In contrast all the other copper(I) monohalides have extended band systems with boundaries ranging from about λ=400 to 540 nm. CuCl yields a blue chemiluminescence, whereas CuBr surprisingly gives a highly saturated (Σ=95 %) intense blue violet (λd=459 nm) emission. CuI displays an overall bluish green emission only due to more intense band systems λ>500 nm. The spectral properties of all the emitters and the color values of the emitters in the 1931‐CIE color diagram are presented.

Improvement of analytical method for chlorine dual‐inlet isotope ratio mass spectrometry of organochlorines
Authors: Gilevska Tetyana , Ivdra Natalija , Bonifacie Magali , Richnow Hans‐Hermann 
Published: October 2015

RationaleThe development of compound‐specific chlorine isotope analysis (Cl‐CSIA) is hindered by the lack of international organochlorine reference materials with isotopic compositions expressed in the δ37Cl notation. Thus, a reliable off‐line analytical method is needed, allowing direct comparison of the δ37Cl values of molecularly different organic compounds with that of ocean‐water chloride, to refer measurement results to a Standard Mean Ocean Chloride (SMOC) scale.MethodsThe analytical method included sealed‐tube combustion of organochlorines, precipitation and subsequent conversion of formed inorganic chlorides into methyl chloride (CH3Cl) for the determination of δ37Cl values by Dual‐Inlet Isotope Ratio Mass Spectrometry (DI‐IRMS). A sample preparation step most sensitive to the sample size – dissolution of the inorganic copper chlorides formed by combustion of organochlorines – was identified.ResultsRecovery of 94 ± 5% of chlorine was reached by applying determined optimal conditions for the dissolution, implying good external precision of δ37Cl values (–0.18 ± 0.03‰, 1σ, n = 3). Validation of the optimized method by the analysis of the produced and initial CH3Cl samples with known δ37Cl values vs SMOC resulted in a difference of 0.11 ± 0.04‰ (1σ, n = 3), confirming the external precision and accuracy of the entire method.ConclusionsThe efficiency of the sample preparation method for CH3Cl‐DI‐IRMS analysis is independent both of the chemical structure of the chlorinated compound and of the amount of chlorine in the sample. This method has the potential to be applied to a broad range of chlorinated organic compounds, e.g. reference material for the calibration of methods for Cl‐CSIA against SMOC.

Published: October 2015

RationaleWhen applying biosynthetic engineering approaches at the early stages of drug discovery, e.g. aiming to develop novel tetracycline analogues, target compounds are generally produced by engineered microorganisms in low yields. Rapid and reliable identification of metabolites with desired structural modification directly from bacterial cultures is therefore of great importance.MethodsStructural elucidation of atypical tetracyclines was carried out by fragmentation applying electrospray ionisation tandem mass spectrometry (ESI‐MS/MS) (triple quadrupole – linear ion trap; Applied Biosystems 4000 QTRAP) and a high‐resolution mass spectrometer (Agilent Technologies 6224 TOF). Fragmentation patterns were obtained either with direct injection or by applying separation of target compounds with high‐performance liquid chromatography (HPLC) prior to mass spectrometry. In‐source and CID fragmentation were compared. Theoretical calculations of target structures using the Gaussian programme suite were carried out with the aim of strengthening experimental structural elucidation.ResultsRecombinant strains of Amycolatopsis sulphurea producing atypical tetracyclines chelocardin, modified chelocardin analogues (9‐demethylchelocardin and 2‐carboxyamido‐2‐deacetyl‐chelocardin (CDCHD), and anhydrotetracycline (ATC) were analysed by collision‐induced dissociation (CID) fragmentation with higher collision energies to yield structurally important fragments which were identified. We have demonstrated that ATC is more prone to fragmentation compared to its epimer, which was further supported by comparison of both structures calculated with ab initio calculations.ConclusionsWe have demonstrated that fragmentation patterns of atypical tetracyclines in CID‐MS spectra enable rapid structural elucidation of target metabolites produced by cultures of genetically engineered bacteria. This method is of significant importance for early stages of drug development considering that isolation of target metabolites produced at low concentration is challenging.

Published: October 2015

AbstractThis article presents a case study of the source‐area treatment of tetrachloroethene (PCE) in a low‐permeability formation using zero‐valent iron (ZVI). Evidence of the stimulation of biological reduction processes within the treatment zone occurred. Pneumatic fracturing and injection of microscale ZVI slurry in the overburden and weathered bedrock zones was performed at a commercial brownfields redevelopment site in Maryland. A 20,000‐square‐foot source area impacted with PCE at concentrations greater than 15,000 µg/L was treated at depths ranging from 10 to 70 feet bgs. An average ZVI dosage of 0.0024 iron‐to‐soil mass ratio within the overburden zone led to a 75 percent decrease in PCE mass in less than one year. For the weathered bedrock zone, an average 0.0045 iron‐to‐soil mass ratio resulted in a 92 percent decrease in PCE mass during the same period. The reducing environment and hydrogen generated by the ZVI may have stimulated Dehalobacter populations, as evidenced by concentrations up to 104 cells per milliliter measured within the treatment area despite a groundwater pH as high as 9. The biological reductive dechlorination of the chlorinated ethenes explains the temporary increase in trichloroethene and cis‐1,2‐dichloroethene concentrations. © 2013 Wiley Periodicals, Inc.
Chlorinated Solvent Treatment Wetland

Published: October 2015

AbstractA first‐of‐its‐kind wetland restoration project was completed in October 2000 to treat trichloroethene‐(TCE‐)impacted groundwater from a former manufacturing facility prior to discharge into a highly valued recreational surface water body in the upper Midwest. This article summarizes the design, construction, operation, and effectiveness of the restored wetland. The groundwater‐surface water discharge zone at the site was restored as a wetland to improve the natural degradation of TCE and subsequent degradation by‐products. For the past 11 years, the treatment wetland performance was evaluated by monitoring the wetland vegetation, wetland hydraulics, and water chemistry. Water quality data have been used to assess the wetland geochemistry, TCE and TCE‐degradation by‐product concentrations within the wetland, and the surface water quality immediately downgradient of the wetland. The treatment wetland has been performing according to design, with TCE and TCE‐degradation by‐products not exceeding surface water criteria. The monitoring results show that TCE and TCE‐degradation by‐products are entering the treatment wetland via natural hydraulic gradients and that the geochemistry of the wetland supports both reductive dechlorination (anaerobic degradation) and cometabolic degradation (aerobic degradation) of TCE and TCE‐degradation by‐products: cis‐ and trans‐1,2‐dichloroethene and vinyl chloride. © 2013 Wiley Periodicals, Inc.
