Authors: Wei Wei , Yeh Jen‐Taut , Li Peng , Li Min‐Rui , Li Wei , Wang Xin‐Ling 
Published: July 2010

AbstractThe effect of nonsolvent on morphologies of electrospun polyamide 6 (PA6) fibers was reported in this study. An investigation of electrospinning PA6 / formic acid (FA) / dichloromethane (DCM) solutions was conducted, wherein FA was used as solvent and DCM was used as nonsolvent for PA6. It is interesting to note that PA6 pellets could dissolve in FA/DCM mixtures with various volume ratios faster than in pure FA. Moreover, the addition of DCM to PA6/FA solution modified the solution properties, that is, conductivity, surface tension, and viscosity. It is found that at any fixed PA6 concentration, the conductivity values and surface tensions values of PA6/FA/DCM solution reduce significantly, whereas the viscosity values of PA6/FA/DCM solution increase significantly, as the volume fraction of DCM in FA/DCM increase. The influences of mixed solvents component on morphological appearance and sizes of the resulting PA6 electrospun fibers were also investigated. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Effect of solid state grinding on properties of PP/PET blends and their composites with carbon nanotubes
Authors: Koysuren Ozcan , Yesil Sertan , Bayram Goknur 
Published: July 2010

AbstractIn this study, it was aimed to improve electrical conductivity and mechanical properties of conductive polymer composites, composed of polypropylene (PP), poly(ethylene terephthalate) (PET), and carbon nanotubes (CNT). Grinding, a type of solid state processing technique, was applied to PP/PET and PP/PET/CNT systems to reduce average domain size of blend phases and to improve interfacial adhesion between these phases. Surface energy measurements showed that carbon nanotubes might be selectively localized at PET phase of immiscible blend systems. Grinding technique exhibited improvement in electrical conductivity and mechanical properties of PP/PET/CNT systems at low PET compositions. Ground composites molded below the melting temperature of PET exhibited higher tensile strength and modulus values than those prepared above the melting temperature of PET. According to SEM micrographs, micron‐sized domain structures were obtained with ground composite systems in which PET was the minor phase. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
On delay‐dependent stabilization of retarded systems—an integral‐inequality based approach
Authors: Song Yan , Wang Jingcheng 
Published: July 2010

AbstractIn this paper, a new integral‐inequality method is proposed by taking both the Leibniz‐Newton formula and the discussed system into account. By using a Lyapunov‐Krasovskii functional approach combined with the new integral inequality, we present the new stabilization criteria for the time‐delay system which employs a memoryless state feedback control law. We exert ourselves to find a less conservative transformation way by bringing the free weighting matrices into the integral inequality, and also these free matrices express greatly the relationships among the system variables and among the terms in the Leibniz‐Newton formula. The techniques applied here improve the results in existing literature. The results obtained by solving LMIs in this note are illustrated to be less conservative comparing with the previous ones. Moreover, numerical examples demonstrate the validity and the evident superiority of the proposed criteria.Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Neural‐network‐based predictive controller design: An application to temperature control of a plastic injection molding process
Authors: Lu Chi‐Huang , Tsai Ching‐Chih , Liu Chi‐Ming , Charng Yuan‐Hai 
Published: July 2010

AbstractThis paper presents a neural‐network‐based predictive control (NPC) method for a class of discrete‐time multi‐input multi‐output (MIMO) systems. A discrete‐time mathematical model using a recurrent neural network (RNN) is constructed and a learning algorithm adopting an adaptive learning rate (ALR) approach is employed to identify the unknown parameters in the recurrent neural network model (RNNM). The NPC controller is derived based on a modified predictive performance criterion, and its convergence is guaranteed by adopting an optimal algorithm with an adaptive optimal rate (AOR) approach. The stability analysis of the overall MIMO control system is well proven by the Lyapunov stability theory. A real‐time control algorithm is proposed which has been implemented using a digital signal processor, TMS320C31 from Texas Instruments. Two examples, including the control of a MIMO nonlinear system and the control of a plastic injection molding process, are used to demonstrate the effectiveness of the proposed strategy. Results from both numerical simulations and experiments show that the proposed method is capable of controlling MIMO systems with satisfactory tracking performance under setpoint and load changes.Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society

Published: July 2010

Abstract

Background
Incisional herniation is a common complication of abdominal aortic aneurysm (AAA) repair. This study investigated whether prophylactic mesh placement could reduce the rate of postoperative incisional hernia after open repair of AAA.

Methods
This randomized clinical trial was undertaken in three hospitals. Patients undergoing elective open AAA repair were randomized to routine abdominal mass closure after AAA repair or to prophylactic placement of polypropylene mesh in the preperitoneal plane.

Results
Eighty-five patients with a mean age of 73 (range 59–89) years were recruited, 77 (91 per cent) of whom were men. There were five perioperative deaths (6 per cent), two in the control group and three in the mesh group (P = 0·663), none related to the mesh. Sixteen patients in the control group and five in the mesh group developed a postoperative incisional hernia (hazard ratio 4·10, 95 per cent confidence interval 1·72 to 9·82; P = 0·002). Hernias developed between 170 and 585 days after surgery in the control group, and between 336 and 1122 days in the mesh group. Four patients in the control group and one in the mesh group underwent incisional hernia repair (P = 0·375). No mesh became infected, but one was subsequently removed owing to seroma formation during laparotomy for small bowel obstruction.

Conclusion
Mesh placement significantly reduced the rate of postoperative incisional hernia after open AAA repair without increasing the rate of complications. Registration number: ISRCTN28485581 (http://www.controlled-trials.com).

Consumer response to tobacco smoke in service settings
Authors: Kraft Frederic B. , Benet Suzeanne B. 
Published: July 2010

Abstract

Establishing smoking policies which accommodate customers' smoking preferences is a major problem for restaurants, bars, hotels, and other firms in the service industry. This study is based on the premise that tobacco smoke can be considered a component of both the physical and ambient retail service environment. Because of legal and ethical concerns, the presence or absence of environmental tobacco smoke (ETS) in two types of eating facilities (bar and fine dining restaurant) was operationalized by the presentation to respondents of photographs which pictured customers in a setting where smoking was either present or absent. The success of this method of manipulation of the treatment variable was assessed with a thought listing procedure. Thought listing responses indicate that both treatments (type of facility and smoking policy) were adequately conveyed by the photographs. Results indicate that cognitive, emotional, and behavioral responses were all negatively affected by the presence of tobacco smoke. The conclusion is that managers who permit smoking in their facilities risk losing non‐smoking patrons while smokers are little affected by either the presence or absence of smoke.
The major contributions of this study include both the exploration of tobacco smoke as part of the retail service environment for eating establishments and the use of thought listings as a manipulation check for variables which were manipulated through use of photographs depicting the treatment conditions.

Haplotype analysis of the CYP2J2 gene associated with myocardial infarction in a Chinese Han population
Authors: Jie Zeng , Hong Kong , Jianhong Tao , Biao Cheng , Yongmei Zhou , Jingchuan Lai 
Published: July 2010

AbstractThe cytochromes P450 epoxygenases CYP2J2 synthesize epoxyeicosatrienoic, which regulate endothelial function. The aim of this study was to assess the association between the human CY2J2 gene and myocardial infarction (MI) in a Chinese population using a haplotype‐based case–control study. There were 440 Chinese Han MI patients and 440 age‐matched control subjects genotyped for three SNPs (rs2271800, rs11572223, and rs14493270) of the human CYP2J2 gene. Haplotypes were constructed and their frequencies compared between the MI patients and the controls. The CC genotype of rs2271800 was found more frequently in the MI group than in the control group (p = 0.004). The frequency of the C–C–G haplotype was significantly higher in MI patients than in control subjects (p < 0.001). The present results indicate that MI is associated with the CC genotype of rs2271800 in the human CYP2J2 gene. The C–C–G haplotype appears to be a useful genetic marker of MI in Chinese Han people.

Authors: Hayashida Kentaro , Louvard Yves , Lefèvre Thierry 
Published: July 2010

AbstractThe “Mother and Child” technique has emerged as a powerful tool for providing additional backup force to conventional guiding catheters. In this report, we show five consecutive cases (including six lesions), in which the “mother and child” technique (five‐in‐six system) solved the problem of lesion access in various coronary arteries and clinical contexts. These cases illustrate the wide‐ranging applicability of the five‐in‐six system for complex lesion treatment in the modern era. © 2010 Wiley‐Liss, Inc.

AbstractObjectives: To evaluate the effectiveness and safety of percutaneous pulmonary valve implantation (PPVI) with routine prestenting with a bare metal stent (BMS). Background: PPVI is a relatively new method of treating patients with repaired congenital heart disease (CHD). Results of PPVI performed with routine prestenting have never been reported. Methods: Consecutive patients who underwent PPVI for homograft dysfunction with prestenting with BMS were studied. The schedule of follow‐up assessment comprised clinical evaluation, cardiovascular magnetic resonance, transthoracic echocardiography, and chest X‐ray to screen for device integrity. Results: PPVI was performed with no serious complications in all patients (n = 10, mean age 26.8 ± 4.0 years, 60% males). In nine patients with significant pulmonary stenosis, peak right ventricular outflow tract (RVOT) gradient was reduced from a mean of 80.6 ± 22.7 to 38.8 ± 10.4 mm Hg on the day following implantation (P = 0.001). At 1‐month and 6‐month follow‐ups, mean RVOT gradient was 34.0 ± 9.8 and 32.0 ± 12.2 mm Hg, respectively. In patients with significant pulmonary regurgitation, mean pulmonary regurgitation fraction decreased from 19% ± 6% to 2% ± 1% (P = 0.0008). Relief of RVOT obstruction and restoration of pulmonary valve competence were associated with significant decrease in right ventricular (RV) end‐diastolic and end‐systolic volumes (125.5 ± 48.6 to 109.2 ± 42.9 mL/m2; P = 0.002 and 68.4 ± 41.5 vs. 50.9 ± 40.6 mL/m2; P = 0.001) as well as improvement in RV ejection fraction (48.8% ± 13.1% to 57.6% ± 14.4%; P = 0.003) and New York Heart Association class (P = 0.003). All patients completed 6‐month follow‐up. No stent fractures were observed. Conclusions: PPVI with routine prestenting with BMS is a safe and effective method of treatment in patients with repaired CHD. © 2010 Wiley‐Liss, Inc.

Published: July 2010

AbstractTraining for structural and adult congenital heart disease interventions remains undeveloped. With the advent of recent percutaneous interventions for the treatment of structural and valvular heart disease, such as transcatheter aortic and pulmonary valve implantation, mitral valve repair, and the expansion of shunt closure procedures, there is a clear need to define the training requirements for this category of procedures. The training needs to be aligned with the goals and priorities of a basic or advanced level and be categorized into acquired and congenital. This document will define the training needs and knowledge base for the developing field of structural heart disease intervention. © 2010 Wiley‐Liss, Inc.
Membrane Bioreactors in Waste Water Treatment – Status and Trends
Authors: Kraume M. , Drews A. 
Published: July 2010

AbstractDue to their unique advantages like controlled biomass retention, improved effluent quality, and decreased footprint, membrane bioreactors (MBRs) are being increasingly used in waste water treatment up to a capacity of several 100,000 p.e. This article reviews the current status of MBRs and reports trends in MBR design and operation. Typical operational and design parameters are given as well as guidelines for waste water treatment plant revamping. To further improve the biological performance, specific or hybrid process configurations are shown to lead to, e.g., enhanced nutrient removal. With regards to reducing membrane fouling, optimized modules, advanced control, and strategies like the addition of flux enhancers are currently emerging.
Are Different Protein Crystal Modifications Polymorphs? A Discussion
Authors: Jones M. J. , Ulrich J. 
Published: July 2010

AbstractDefining terminology and nomenclature in such a manner that important features and properties of a system or phenomena for which a description is sought are succinctly captured is a task fraught with difficulty, in particular when dealing either with complex or subtle issues. The recent exchanges in the literature regarding the terminology applied to co‐crystals and solvates (pseudopolymorphs) is a case in point. The result of these discussions is that there is still no consistent usage, and perhaps there will never be. Nonetheless, it is one thing to disagree about nomenclature and quite another to misuse it and it is one of these misuses that this paper will broach, namely the designation of different crystalline phases of one and the same protein as polymorphs. Based upon the crystallization behavior and the structural properties of the resulting protein crystals, it will be shown that the term is anything but appropriate. The nature of protein crystals will be discussed here with reference to structural aspects and crystal types of small molecules and ionic crystals in order to identify the similarities to crystalline proteins as well as any differences. It will become clear that protein crystals are always solvates and, as far as experimental evidence allows to make a clear statement, often solvates of salts. Quite clearly, however, the use of the term polymorph to describe different crystal modifications cannot be justified unless it can be clearly shown that the modifications it is applied to have exactly the same chemical composition. In practice, this has yet to be shown and it is therefore recommended merely to use the word modification to distinguish different crystalline phases of a given protein.
Design, Synthesis, Photophysics, and Anion‐Binding Studies of Bis(dicyclohexylphosphino)methane‐Containing Dinuclear Gold(I) Thiolate Complexes with Urea Receptors

Published: July 2010

AbstractA series of bis(dicyclohexylphosphino)methane (dcpm)‐containing gold(I) thiolate complexes with urea receptors, 1–3, has been successfully designed and synthesized, and their photophysical and anion‐binding properties have been studied. The linker between the thiolate and the urea group, and the electronic environment of the urea moiety, have been found to exert a great influence on the photophysical and anion‐binding properties of the complexes. Complex 3 displays an intense long‐lived orange‐red luminescence at around 620 nm in the solid state and in the glass state at 77 K, which is considerably red shifted from the band seen in a solution of dichloromethane at room temperature, suggesting the presence of Au⋅⋅⋅Au interactions. Upon introducing an electron‐withdrawing NO2 group, complex 1 was found to show high selectivity and sensitivity for F− through a drastic color change from yellow to red. The anion‐binding constants of the complexes have been determined from electronic absorption and 1H NMR spectroscopy titration studies and the data were found to fit well to a 1:1 binding model for the interactions between the complexes and the anions. Complexes 1 and 2 show the same anion selectivity trend of F−>AcO−>H2PO4−>Cl−≈Br−≈I−, which is consistent with the trend in anion basicity. In addition, complex 1 has been shown to exhibit higher binding affinity for anions compared with those of complexes 2 and 3, probably due to the higher acidity of the urea moiety as a result of the introduction of the NO2 group.
