The reinvestments into the civil engineering buildings in Germany can be substantially lowered by an extension of their service life. This paper gives an overview of methods which were developed by the Collaborative‐Research‐Center SFB 477 “Life cycle assessment of structures via innovative monitoring” at the Technischen Universität Braunschweig. The main topic is the lifetime assessment of old steel buildings by monitoring, followed by an overview of different methods to determine the inherent damage in the structure. The reliable determination of weak points in the building is described and the correct choice of the monitoring strategy for a weak detail is explained. A procedure is presented to determine the life expectancy of fatigue‐stressed buildings by monitoring and further attempts. The article is closed by a section over the flaw detection at buildings by using piezo arrays.

AbstractDer vorliegende Beitrag erläutert den ersten Abschnitt des baulichen Werdeganges der beiden neuen Brückenbauwerke B0351 “Südbahnhofbrücke“ (Straßen‐, Rad‐ und Fußgängerbrücke) und B0352 “Arsenalsteg“ (Fußgänger‐ und Radfahrersteg), welche die Gleisanlagen im Osten des zukünftigen Hauptbahnhofes Wien überspannen. Mit dem Bau der neuen Brücken im Auftrag der Stadt Wien, Magistratsabteilung 29 (MA 29) – Brückenbau und Grundbau, werden die Stadtentwicklungsgebiete im Nahbereich des künftigen Hauptbahnhofes besser verknüpft. Für Bahnreisende stellen die beiden Brücken eine einladende Geste dar – eine Vorankündigung des zukünftigen Hauptbahnhofes gleichsam als Tor zur Stadt.Construction of the southern section of the Südbahnhofbrücke and the Arsenalsteg in the course of the development of the new central railway station of Vienna, Austria. This article covers the first phase of construction of the new bridges B0351 “Südbahnhofbrücke” (roadway, bicycle lane and pedestrian bridge) and the B0352 “Arsenalsteg” (pedestrian and bicycle lane bridge), spanning the railways in the eastern part of the future central railway station of Vienna, Austria. With the realisation of these new bridges on behalf of the city of Vienna, Municipal Department 29 (MA 29) – Bridge Construction and Foundation Engineering, the urban development areas around the new central railway station will be better connected. The new bridges will act as a new doorway to Vienna and be perceived, by the railway travellers, as an invitation to the city, heralding the future central railway station.

An M‐Rice wind speed frequency distribution
Authors: Baïle R. , Muzy J.‐F. , Poggi P. 
Published: October 2011

ABSTRACTSeveral known statistical distributions can describe wind speed data, the most commonly used being the Weibull family. In this paper, a new law, called ‘M‐Rice’, is proposed for modeling wind speed frequency distributions. Inspired by recent empirical findings that suggest the existence of some cascading process in the mesoscale range, we consider that wind speed can be described by a seasonal AutoRegressive Moving Average (ARMA) model where the noise term is ‘multifractal’, i.e. associated with a random cascade. This leads to the distribution of wind speeds according to the M‐Rice probability distribution function, i.e. a Rice distribution multiplicatively convolved with a normal law. A comparison based on the estimation of the mean wind speed and power density values as well as on the different goodness‐of‐fit tests (the Kolmogorov–Smirnov test, the Kuiper test and the quantile–quantile plot) was made between this new distribution and the Weibull distribution for 35 data sets of wind speed from the Netherlands and Corsica (France) sites. Accordingly, the M‐Rice and Weibull distributions provided comparable performances; however, the quantile–quantile plots suggest that the M‐Rice distribution provides a better fit of extreme wind speed data. Beyond these good results, our approach allows one to interpret the observed values of Weibull parameters. Copyright © 2011 John Wiley & Sons, Ltd.
Applications of Stereospecifically‐Labeled Fatty Acids in Oxygenase and Desaturase Biochemistry
Authors: Brash Alan R. , Schneider Claus , Hamberg Mats 
Published: October 2011

AbstractOxygenation and desaturation reactions are inherently associated with the abstraction of a hydrogen from the fatty acid substrate. Since the first published application in 1965, stereospecific placement of a labeled hydrogen isotope (deuterium or tritium) at the reacting carbons has proven a highly effective strategy for investigating the chemical mechanisms catalyzed by lipoxygenases, hemoprotein fatty acid dioxygenases including cyclooxygenases, cytochromes P450, and also the desaturases and isomerases. This review presents a synopsis of all published studies through 2010 on the synthesis and use of stereospecifically labeled fatty acids (71 references), and highlights some of the mechanistic insights gained by application of stereospecifically labeled fatty acids.
Electroacupuncture alleviates affective pain in an inflammatory pain rat model

Published: October 2011

AbstractPain has both sensory–discriminative and emotional–affective dimensions. Previous studies demonstrate that electroacupuncture (EA) alleviates the sensory dimension but do not address the affective. An inflammatory pain rat model, produced by a complete Freund adjuvant (CFA) injection into the hind paw, was combined with a conditioned place avoidance (CPA) test to determine whether EA inhibits spontaneous pain‐induced affective response and, if so, to study the possibility that rostral anterior cingulate cortex (rACC) opioids underlie this effect. Male Sprague–Dawley rats (250–275 g, Harlan) were used. The rats showed place aversion (i.e. affective pain) by spending less time in a pain‐paired compartment after conditioning than during a preconditioning test. Systemic non‐analgesic morphine (0.5 and 1.0 mg/kg, i.p.) inhibited the affective reaction, suggesting that the affective dimension is underpinned by mechanisms different from those of the sensory dimension of pain. Morphine at 0.5 and at 1 mg/kg did not induce reward. Rats given EA treatment before pain‐paired conditioning at GB 30 showed no aversion to the pain‐paired compartment, indicating that EA inhibited the affective dimension. EA treatment did not produce reward or aversive effect. Intra‐rACC administration of D‐Phe‐Cys‐Tyr‐D‐Trp‐Orn‐Thr‐Pen‐Thr amide (CTOP), a selective mu opioid receptor antagonist, but not norbinaltorphimine (nor‐BNI), a selective kappa opioid receptor antagonist, blocked EA inhibition of the affective dimension. These data demonstrate that EA activates opioid receptors in the rACC to inhibit pain‐induced affective responses and that EA may be an effective therapy for both the sensory–discriminative and the affective dimensions of pain.
COUNTING PERMUTATIONS BY NUMBERS OF EXCEDANCES, FIXED POINTS AND CYCLES
Authors: MA SHI-MEI 
Published: October 2011

AbstractIn this paper we present a combinatorial proof of an identity involving the two kinds of Stirling numbers and the numbers of permutations with prescribed numbers of excedances and cycles. Several recurrence relations related to the numbers of excedances, fixed points and cycles are also obtained.
BOUNDED AND FULLY BOUNDED MODULES

Published: October 2011

AbstractGeneralizing the concept of right bounded rings, a module MR is called bounded if annR(M/N)≤eRR for all N≤eMR. The module MR is called fully bounded if (M/P) is bounded as a module over R/annR(M/P) for any ℒ2-prime submodule P◃MR. Boundedness and right boundedness are Morita invariant properties. Rings with all modules (fully) bounded are characterized, and it is proved that a ring R is right Artinian if and only if RR has Krull dimension, all R-modules are fully bounded and ideals of R are finitely generated as right ideals. For certain fully bounded ℒ2-Noetherian modules MR, it is shown that the Krull dimension of MR is at most equal to the classical Krull dimension of R when both dimensions exist.
AN EXTENSION OF SURY’S IDENTITY AND RELATED CONGRUENCES
Authors: MEŠTROVIĆ ROMEO 
Published: October 2011

AbstractIn this paper we give an extension of a curious combinatorial identity due to B. Sury. Our proof is very simple and elementary. As an application, we obtain two congruences for Fermat quotients modulo p3. Moreover, we prove an extension of a result by H. Pan that generalizes Carlitz’s congruence.
Self-consistent dynamics of electromagnetic pulses and wakefields in laser-plasma interactions
Authors: Bonatto A. , Pakter R. , Rizzato F.B. 
Published: October 2011

AbstractIn the present analysis we study the time dependent, self-consistent propagation of nonlinear electromagnetic pulses in plasmas. Interactions of the electromagnetic pulses and wakefields are fully taken into account, from which one obtains accurate information on pulse time dependent dynamics and stability. While wide pulses may or may not retain the localized shape depending on their power, narrower pulses always tend to delocalize as time evolves.
Consumer perspectives in surgical research and audit
Authors: Ahern Eleanor , Thavaneswaran Prema , Babidge Wendy , Maddern Guy J. 
Published: October 2011

Objectives: The aim was to learn about perspectives of consumers contributing to the work of the Division of Research, Audit and Academic Surgery of the Royal Australasian College of Surgeons. The research arm of the Division has worked with consumers since it was formed in 1998.Methods: Nine consumers who worked with the Division over the past 5 years completed (1) a written survey focused on their background and past experience, and (2) a semi-structured phone interview focused on their motivations for becoming involved in this work; their role; the evolution of the role of consumers in healthcare research; and what health information for consumers should contain.Results: Participants came from various backgrounds and had different motivations for being involved. A common theme was concern about uncertainties in surgery and the need to provide consumers with information about potential benefits and risks of a procedure. Participants believed that a consumer presence was vital in research on surgical procedures, and that the content and wording of consumer information must be chosen carefully in order for the public to use it in a meaningful way. They also acknowledged the changing role of the consumer, who was rapidly becoming a partner in the doctor–patient relationship.Conclusions: In surgical research and audit, the consumer perspective is unique and informed by a wealth of experience. The findings of this study may be of interest to other health technology assessment and associated agencies seeking to involve consumers within their own research process.
Decision aid for women considering breast cancer screening

Published: October 2011

Objectives: The aim of this study was to describe the process and challenges of developing a decision aid for the national public breast cancer screening program in Finland.Methods: An expert team with stakeholder representation used European guidelines and other literature as basis for selecting relevant content and format for the decision aid for breast cancer screening. Feedback from women was sought for the draft documents.Results: A decision aid attached to the invitation letter for screening was considered the best way to ensure access to information. In addition, tailored letter templates for all phases of the screening program, a poster, and a public website were developed. Initial feedback from users (women, professionals, and service providers), was mainly positive. Six months after publishing, the implementation of the decision aid was still incomplete.Conclusions: Providing balanced information for women invited to breast cancer screening is demanding and requires careful planning. Professionals and service providers need to be engaged in the HTA process to ensure proper dissemination and implementation of the information. End user participation is essential in the formulation of information. There is a need to follow up the implementation of the decision aid.

Published: October 2011

AbstractMonoamines, such as serotonin, dopamine, and norepinephrine, play a crucial role in the regulation of emotion processing and mood. In this study, we investigated how polymorphisms of the serotonin transporter (5-HTT) and catechol-O-methyltransferase (COMT) influence emotion recognition abilities. We recruited 88 female undergraduate students and assessed 5-HTT genotype and the COMT Val158Met polymorphism. The subjects completed two computerized tasks: The Penn Emotion Recognition Test (ER40) and the Penn Emotion Acuity Test (PEAT). For the ER40, we found that s-allele carriers performed significantly worse in the recognition of happy faces, but did better in the recognition of fearful faces, compared with homozygous l-carriers of the 5-HTT gene. Neither 5-HTT nor COMT genotypes influenced the ability to discriminate between different intensities of sadness or happiness on the PEAT. Moreover, there was no significant interaction between the two polymorphisms in their effect on performance on the ER40 or the PEAT. (JINS, 2011, 17, 1014–1020)

Authors: Bucknum Michael , Castro Eduardo 
Published: October 2011

AbstractDiffraction data taken from nanocrystalline n-diamond and i-carbon forms is fit to a so-called glitter model, in which the geometry of the C lattice has been optimized by density functional theory (DFT). A calculated theoretical diffraction pattern for glitter is shown to be a close fit to the experimental data for these novel C forms.
The ePetri dish, an on-chip cell imaging platform based on subpixel perspective sweeping microscopy (SPSM)

Published: October 2011

We report a chip-scale lensless wide-field-of-view microscopy imaging technique, subpixel perspective sweeping microscopy, which can render microscopy images of growing or confluent cell cultures autonomously. We demonstrate that this technology can be used to build smart Petri dish platforms, termed ePetri, for cell culture experiments. This technique leverages the recent broad and cheap availability of high performance image sensor chips to provide a low-cost and automated microscopy solution. Unlike the two major classes of lensless microscopy methods, optofluidic microscopy and digital in-line holography microscopy, this new approach is fully capable of working with cell cultures or any samples in which cells may be contiguously connected. With our prototype, we demonstrate the ability to image samples of area 6 mm × 4 mm at 660-nm resolution. As a further demonstration, we showed that the method can be applied to image color stained cell culture sample and to image and track cell culture growth directly within an incubator. Finally, we showed that this method can track embryonic stem cell differentiations over the entire sensor surface. Smart Petri dish based on this technology can significantly streamline and improve cell culture experiments by cutting down on human labor and contamination risks.

Neuromuscular Disorders Associated With Hepatitis B Virus Infection
Authors: Stübgen Joerg-Patrick 
Published: October 2011

Abstract

Approximately 400 million worldwide are chronically infected with the hepatitis B virus (HBV). During the course of illness, approximately 20% of patients develop disease manifestations outside the liver. Neuropathy develops in approximately 5% of patients with chronic HBV infection and rarely during acute HBV infection. The pathogenesis of the various HBV-associated neuropathy syndromes possibly involves deposition of immune complexes in nerves or blood vessel walls. Direct viral infection of nerves has not been demonstrated. Management entailed supportive care with antiviral and immunomodulatory treatment as clinically indicated. Rare cases of muscle disease, mostly inflammatory myopathy, have been associated with HBV infection. Presumably, HBV-associated antigens trigger immune mechanisms directed against components of muscle tissue. There is no evidence of replicative virus infection of muscle fibers. Management entailed immunomodulatory treatment, occasionally with anti-HBV therapy. Physicians should be aware that HBV infection has the potential to trigger presumed immune-mediated neuromuscular syndromes.

Objective To compare different modes of pain management following video-assisted thoracoscopic surgery (VATS) to our national standard. Methods This is an audit based on patient's experiences. One hundred consecutive patients who underwent VATS with or without pleurodesis were managed by one of the following pain relief pathways: (A) thoracic paravertebral block + morphine patient-controlled analgesia (PCA), (B) percutaneous thoracic paravertebral catheter +/– morphine PCA, (C) thoracic epidural +/– morphine PCA, (D) morphine PCA alone, and (E) intravenous or subcutaneous morphine as required. Pain score was documented up to four times per day for each patient. The incidence of severe pain was defined as visual analog scale ≥7. The results were compared with the standard set by the audit commission for postoperative pain relief in the UK. The mean daily pain scores were calculated retrospectively for all patients. Results There were no statistically significant differences in mean daily pain scores irrespective of having a pleurodesis. The percentage of patients experiencing severe pain was 34% [mean visual analog scale = 8 (standard deviation = 1.0)]. This was almost seven times the standard. Among these pathways, B had the least percentage incidence of severe pain (16.7%) followed by A (25.0%) D (33.3%), C (35.7%), and E (52.4%). Conclusions We are not compliant with the standards set by the audit commission. Pain management in theater recovery needs to be targeted. In the light of these results, we recommend the use of percutaneous thoracic paravertebral catheter +/– morphine PCA for postoperative VATS pain relief.

Published: October 2011

Objective The placement of epicardial pacing wires before weaning from bypass during port-access heart surgery can be difficult or impossible. Sometimes, it is necessary to pacing the patient to wean from bypass, and it is problematic to exchange the Edwards pulmonary vent (EndoVent) for a pace catheter under the drapes. Our objective was to devise an effective means of pacing the patient using the pulmonary vent catheter. Methods All patients having aortic valve minimally invasive port-access surgery have a pacing wire deployed through the Edwards EndoVent catheter. We did a retrospective chart analysis of these cases. Results After reviewing the anesthesia records, we determined that we were able to reliably convert the pulmonary vent catheter, which is beneficial for the surgery, into a pacing catheter before weaning from bypass 100% of the time. The mean pacing threshold current was 1.60 mA with the wire in the right ventricular apex. Conclusions We found that in all 25 patients we were able to rapidly convert the vent catheter into a reliable pacing catheter without any complications.
