Friedensbrücke für Lyon
Authors: Keil Andreas , Zimmermann Michael , Deillon Arnaud 
Published: February 2015

AbstractDie 220 m lange Fußgängerbrücke in Lyon überspannt die rund 160 m breite Rhône in einem Bogen mit flachem Stich. Dickwandige Stahlrohre bilden einen Dreigurt, der an den Ufern eingespannt ist. Die Stahlkonstruktion ist mit einem leichten Holzbelag versehen. Durch die Minimierung der Elemente wird eine maximale Transparenz erreicht. Die Treppen, die entlang der Bögen nach unten geführt werden, erschließen die Uferbereiche und bilden eine spannende Wegeführung vom Ufer der Rhône zum zentralen Platz. Zusammen mit dem Architekturbüro DFA Dietmar Feichtinger Architectes, Paris, und der Unterstützung des Bauherrn GRAND LYON, konnte dieser gestalterisch und technisch anspruchsvolle Brückenentwurf realisiert und auf die örtlichen Bedingungen maßgeschneidert werden. Im Folgenden werden Entwurfsidee, Konstruktion und Berechnung dargestellt sowie ein Überblick über Fertigung und Montage der Brücke vermittelt.Peace bridge for Lyon. The 220 m long pedestrian bridge in Lyon spans in a smooth way over the 160 m wide river Rhône. The elements of the three‐chord truss alter their position along the bridge and create a flat, wide V in the middle of the bridge. The steel structure is covered with light wooden planks. Through minimization of the elements maximum transparency is achieved. Between the direct connection straight to both city parts stairs are leading to the path along the shore, attached to each side of the bridge along the side of the three‐chord truss. Together with the architects DFA Dietmar Feichtinger Architectes, Paris, and the support of the client GRAND LYON, this technically challenging bridge design could be realized and adapted to local conditions. The following text provides details about the design idea, design and structural analysis, as well as an overview of assembly and erection of the bridge.
An analytical expression to determine “realistic” shear buckling stress in cold‐formed lipped channels
Authors: Bedair Osama 
Published: February 2015

AbstractCurrent North American and European design provisions ignore the rotational restraint when evaluating local web shear buckling stresses in cold‐formed steel channels. This paper offers a new analytical expression for computing local buckling shear stresses in cold‐formed channel members taking into account the rotational restraints imposed by the flanges and the lips. The expression derived is suitable for hand calculations and can replace current code expressions in order to achieve economical steel designs. Comparisons with existing design formulas currently used in practice for the limiting conditions show a difference within 5 %.
Tensile load‐carrying behaviour of elastomeric bearings
Authors: Mano Toshihisa , Mangerig Ingbert 
Published: February 2015

AbstractElastomeric bearings for seismic isolation applications can be subjected to tensile loads depending on the geometrical configuration, high vertical seismic motion or excessive horizontal deformation due to the elongated‐period horizontal motion. It is a known fact that cavities develop within elastomeric material when it undergoes a certain amount of tensile force in a very constrained condition since a high hydrostatic tensile stress builds up. Once these cavities have developed, the tensile stiffness of the bearing drops dramatically. This paper contributes to understanding this phenomenon itself and its influence on the basic properties of elastomeric bearings. For this purpose, two types of elastomeric bearing were tested and the cavitation phenomenon observed. Moreover, those test results are compared with the FE simulation results from the modified hyperelastic material model with the cavity damage criterion. The two‐phase softening model presented here can simulate the real softening behaviour of elastomeric bearings well, and it may even help us grasp a better insight into the cavitation phenomenon.
Traffic‐induced vibration analysis of a steel girder bridge compared with a concrete bridge
Authors: Tsubomoto Masahiko , Kawatani Mitsuo , Mori Kengo 
Published: February 2015

AbstractAt the preliminary design stage for a highway bridge 81 m long, a three‐span continuous girder, including a span of about 30 m, is preferable from the point of construction cost. Generally, the concern is that girder bridges with spans of 30 m, which have a fundamental natural frequency of about 3 Hz, have large traffic‐induced vibrations due to the coupling dynamic response with heavy vehicles having a bouncing natural frequency of about 3 Hz. Furthermore, large traffic‐induced vibration in girder bridges causes low‐frequency sound (LFS) as one of the environmental vibration problems. Two kinds of girder bridge with a length of 81 m – a concrete hollow slab bridge and an eight‐girder steel bridge with the same spans – are proposed. For assessing the low‐frequency sound radiated from bridges, firstly, the traffic‐induced vibrations of two kinds of girder bridge are compared with each other by analysing the coupling dynamic response of bridges due to moving heavy vehicles in a dynamic system.

Published: February 2015

ABSTRACTObjectiveTo define the contribution of maternal variables which influence the measured level of maternal serum placental growth factor (PlGF) in screening for pregnancy complications.MethodsMaternal characteristics and medical history were recorded and serum levels of PlGF were measured in women with a singleton pregnancy attending for three routine hospital visits at 11 + 0 to 13 + 6, 19 + 0 to 24 + 6 and 30 + 0 to 34 + 6 or 35 + 0 to 37 + 6 weeks' gestation. For women delivering phenotypically normal live births or stillbirths ≥ 24 weeks' gestation, variables from maternal demographic characteristics and medical history important in the prediction of PlGF were determined from a linear mixed‐effects multiple regression.ResultsSerum levels of PlGF were measured in 38 002 cases in the first trimester, 10 281 in the second trimester and 12 392 in the third trimester. Significant independent contributions to serum PlGF were provided by gestational age, maternal age, weight and racial origin, cigarette smoking, diabetes mellitus, and gestational age at delivery and birth‐weight Z‐score of the neonate in the previous pregnancy. The machine used to measure serum PlGF was also found to have a significant effect. Allowing for other factors, the effect of maternal age on PlGF changed over the three trimesters, whereas other variables had constant effects over the three trimesters. Random‐effects multiple regression analysis was used to define the contribution of maternal variables that influence the measured serum PlGF and express the values as multiples of the median (MoMs). The model was shown to provide an adequate fit of MoM values for all covariates, both in pregnancies that developed pre‐eclampsia and in those without this complication.ConclusionsA model was fitted to express the measured level of maternal serum PlGF across the three trimesters of pregnancy as MoMs, after adjusting for variables of maternal characteristics and medical history that affect this measurement.

AbstractBackground
Post‐pancreatic surgical morbidity is frequent but often manageable by less invasive means than re‐operation. Yet, some complications can become hazardous and life threatening. Herein, the results of a completion pancreatectomy (CP) to cope with severe post‐operative pancreatic fistulas (POPF) and bleeding complications after major pancreatic resections for suspected pancreatic malignancy are presented.MethodsCPs to treat severe post‐pancreatic index‐surgery complications between January 2002 and January 2012 were selected out of a prospective database. Indications for CP as well as perioperative data were prospectively collected and retrospectively assessed.ResultsIn 20 of 521 Kausch–Whipple Resections (3.8 %), a CP was necessary to treat post‐index surgery morbidity. Indications included insufficiency of the pancreaticojejunal anastomosis with resulting POPF in 14 (70.0 %) patients, severe bleeding complications in 6 (30.0 %) patients, and a severe portal vein thrombosis in 1 (5.0 %) patient. In 7 (35.0 %) of the 20 patients, the course was complicated by remnant pancreatitis. Eleven (55.0 %) of the 20 patients died during the hospital stay. Median time to re‐operation did not significantly differ between survivors and in‐hospital deaths (10.0 vs. 8.0 days; p = 0.732). Median hospital stay of the surviving patients was 31.0 (range 10–113) days. Re‐operations following CPs were necessary in 5 (55.6 %) of the 9 patients who survived and in 9 (81.8 %) out of 11 patients who died.ConclusionsPost‐pancreatic resection complications can become hazardous and result in severely ill patients requiring maximum therapy. CP in these cases has a high mortality but serves as an ultima ratio to cope with deleterious complications.

AbstractBackgroundPostoperative pain remains a significant challenge following laparoscopy. Aerosolized intraperitoneal local anesthetic (AILA) is a novel method to deliver local anesthetic. The aim was to evaluate aerosolized ropivacaine in pain management following laparoscopic Nissen fundoplication (LNF) and cholecystectomy (LC).MethodsThis prospective randomized double‐blinded placebo‐controlled trial enrolled consecutive patients undergoing LNF and LC. The treatment group (TG) received intraperitoneal ropivacaine (5 mL 1 %Naropin®) at CO2 insufflation via the AeroSurge® aerosolizer device through the camera port. The control group (CG) received 5 mL of saline in the same manner. Postoperative shoulder tip pain at rest 6 h postoperatively was the primary study endpoint, with secondary endpoints of shoulder and abdominal pain within the first 24 h, recovery room stay, hospital stay, and postoperative analgesia use. Pain scores were collected using the Verbal Rating Score.ResultsEighty‐seven patients were included in the final analysis (TG n = 40, CG n = 47). There was no significant difference between CG and TG at the primary endpoint. In the LC group, AILA significantly reduced shoulder tip pain at rest at 10 (p = 0.030) and 30 min (p = 0.040) and shoulder tip pain on movement at 10 (p = 0.030) and 30 min (p = 0.037). In the LNF group, AILA significantly reduced postoperative abdominal pain at rest at 6 h (p = 0.009). AILA reduced overall incidence of shoulder tip pain in the LC group (11.8 vs. 57.9 %, p = 0.004).ConclusionThis study did not demonstrate a significant difference between TG and CG in the primary endpoint, pain at 6 h postoperatively.
Macrometastasis, Micrometastasis, and Isolated Tumor Cells in Sentinel Lymph Nodes of Early Breast Cancers: A 10‐Year Histopathological and Survival Analysis of 537 Asian Patients
Authors: Co Michael , Kwong Ava 
Published: February 2015

AbstractBackgroundIn patients with negative sentinel lymph node biopsy (SLNB), axillary dissection (AD) can be avoided to reduce morbidities. However, there is only limited data on the rate of positive non‐SLN (NSLN) in those who have micrometastasis and isolated tumor cells (ITC) in the literature.MethodsWe did a retrospective review of all clinically node‐negative breast cancer patients with SLNB done at our unit from January 2001 to June 2011. Multivariate analysis was adopted to evaluate the risk factors for NSLN metastasis. Difference in 5‐year disease‐free survival (DFS) was evaluated with log‐rank test.ResultsFive‐hundred and thirty‐seven patients underwent SLNB; 161 (30 %) had positive SLN on frozen section (FS), 50 of these patients (31 %) had NSLN metastasis, 25 patients had negative SLN on FS but were found to have micrometastasis on histopathology, and only 1 (4 %) of them had NSLN metastasis, while 14 patients were found to have ITC in SLN; none of them had NSLN metastasis. Multivariate analysis found that the number of SLN harboring micrometastasis is the only independent risk factor for NSLN metastasis in patients with micrometastasis (p value = 0.008). On the contrary; tumor size, grade, and biology were not associated with NSLN metastasis. 5‐year DFS in patients with macrometastasis in SLN was 94.2 %, while that in patients with micrometastasis and ITC was 100 % (p value <0.001).ConclusionNSLN metastasis in those who only have micrometastasis and ITC is rare, and 5‐year DFS is significantly better in this group of patients as well. It is therefore a routine practice in our unit to omit AD in patients with micrometastasis and ITC on SLN.
The syntax of anaphoric possessives in Hungarian
Authors: Dékány Éva 
Published: February 2015

AbstractStarting with the seminal work of Szabolcsi, morphologically unmarked and Dative-marked possessors in Hungarian have been the subject of rich investigation. Anaphoric possessive constructions, however, have remained poorly researched. In these possessives the possessor bears the mysterious-ésuffix and the covert possessum is interpreted under identity with an antecedent. This paper presents new evidence in favour of Bartos’ (2001) analysis of anaphoric possessives, which holds that-éis the Genitive case. I further argue that anaphoric possessives in Hungarian involve a pro-form rather than deletion of a lexical noun, and this accounts for the restricted modification of the possessum.

AbstractBackgroundOutcomes related to prophylactic catheter ablation (PCA) for ventricular tachycardia (VT) before implantable cardioverter‐defibrillator (ICD) implantation in non‐ischemic cardiomyopathy (NICM) are not well characterized. We assessed the efficacy of single endocardial PCA in NICM patients.MethodsWe retrospectively analyzed 101 consecutive NICM patients with sustained VT. We compared clinical outcomes of patients who underwent PCA (ABL group) with those who did not (No ABL group). Successful PCA was defined as no inducible clinical VT. We also compared the clinical outcomes of patients with successful PCA (PCA success group) with those of the No ABL group. Endpoints were appropriate ICD therapy (shock and anti‐tachycardia pacing) and the occurrence of electrical storm (ES).ResultsPCA was performed in 42 patients, and it succeeded in 20. The time to ES occurrence was significantly longer in the ABL group than in the No ABL group (p=0.04). The time to first appropriate ICD therapy and ES occurrence were significantly longer in the PCA success group than in the No ABL group (p=0.02 and p<0.01, respectively).ConclusionSingle endocardial PCA can decrease ES occurrence in NICM patients. However, high rates of VT recurrence and low success rates are issues to be resolved; therefore, the efficacy of single endocardial PCA is currently limited.

AbstractBackgroundDifficulties with performance of functional activities may result from cognitive and/or physical impairments. To date, there has not been a clear delineation of the physical and cognitive demands of activities of daily living.ObjectivesTo quantify the relative physical and cognitive demands required to complete typical functional activities in older adults.DesignExpert panel survey.SettingWeb‐based platform.ParticipantsEleven experts from 8 academic medical centers and 300 community‐dwelling elderly adults age 70 and older scheduled for elective noncardiac surgery from 2 academic medical centers.MethodsSum scores of expert ratings were calculated and then validated against objective data collected from a prospective longitudinal study.Main Outcome MeasurementsCorrelation between expert ratings and objective neuropsychologic tests (memory, language, complex attention) and physical measures (gait speed and grip strength) for performance‐based tasks.ResultsManaging money, self‐administering medications, using the telephone, and preparing meals were rated as requiring significantly more cognitive demand, whereas walking and transferring, moderately strenuous activities, and climbing stairs were assessed as more physically demanding. Largely cognitive activities correlated with objective neuropsychologic performance (r = 0.13‐0.23, P < .05) and largely physical activities correlated with physical performance (r = 0.15‐0.46, P < .05).ConclusionsQuantifying the degree of cognitive and/or physical demand for completing a specific task adds an additional dimension to standard measures of functional assessment. This additional information may significantly influence decisions about rehabilitation, postacute care needs, treatment plans, and caregiver education.

OBJECTIVETo better understand tuberculosis (TB) infection control (IC) in healthcare facilities (HCFs) in Georgia.DESIGNA cross-sectional evaluation of healthcare worker (HCW) knowledge, beliefs and behaviors toward TB IC measures including latent TB infection (LTBI) screening and treatment of HCWs.SETTINGGeorgia, a high-burden multidrug-resistant TB (MDR-TB) country.PARTICIPANTSHCWs from the National TB Program and affiliated HCFs.METHODSAn anonymous self-administered 55-question survey developed based on the Health Belief Model (HBM) conceptual framework.RESULTSIn total, 240 HCWs (48% physicians; 39% nurses) completed the survey. The overall average TB knowledge score was 61%. Only 60% of HCWs reported frequent use of respirators when in contact with TB patients. Only 52% of HCWs were willing to undergo annual LTBI screening; 48% were willing to undergo LTBI treatment. In multivariate analysis, HCWs who worried about acquiring MDR-TB infection (adjusted odds ratio [aOR], 1.7; 95% confidence interval [CI], 1.28–2.25), who thought screening contacts of TB cases is important (aOR, 3.4; 95% CI, 1.35–8.65), and who were physicians (aOR, 1.7; 95% CI, 1.08–2.60) were more likely to accept annual LTBI screening. With regard to LTBI treatment, HCWs who worked in an outpatient TB facility (aOR, 0.3; 95% CI, 0.11–0.58) or perceived a high personal risk of TB reinfection (aOR, 0.5; 95% CI, 0.37–0.64) were less likely to accept LTBI treatment.CONCLUSIONThe concern about TB reinfection is a major barrier to HCW acceptance of LTBI treatment. TB IC measures must be strengthened in parallel with or prior to the introduction of LTBI screening and treatment of HCWs.Infect Control Hosp Epidemiol 2015;00(0): 1–7
A thermodynamically consistent phase-field model for two-phase flows with thermocapillary effects
Authors: Guo Z. , Lin P. 
Published: February 2015

AbstractIn this paper, we develop a phase-field model for binary incompressible (quasi-incompressible) fluid with thermocapillary effects, which allows for the different properties (densities, viscosities and heat conductivities) of each component while maintaining thermodynamic consistency. The governing equations of the model including the Navier–Stokes equations with additional stress term, Cahn–Hilliard equations and energy balance equation are derived within a thermodynamic framework based on entropy generation, which guarantees thermodynamic consistency. A sharp-interface limit analysis is carried out to show that the interfacial conditions of the classical sharp-interface models can be recovered from our phase-field model. Moreover, some numerical examples including thermocapillary convections in a two-layer fluid system and thermocapillary migration of a drop are computed using a continuous finite element method. The results are compared with the corresponding analytical solutions and the existing numerical results as validations for our model.
Thermocapillary migration and interaction of drops: two non-merging drops in an aligned arrangement
Authors: Yin Zhaohua , Li Qiaohong 
Published: February 2015

AbstractA numerical study on the interaction of two spherical drops in thermocapillary migration in microgravity is presented. Unequal drop sizes in the axisymmetric model lead to strong drop interaction if the leading drop is smaller. The effect of the ratio of the two drop radii, their initial distance apart, and non-dimensional numbers on the interaction is studied in the case of non-merging drops in detail. The Marangoni number adopted in this paper is fairly large (around 100) so as to reveal the phenomena of real flows. As a result, the heat wake behind the leading drop plays an important role in drop interaction, and obviously different final drop distances and transient migration processes are observed for various sets of non-dimensional numbers. The influence of drop deformation on drop interaction is also investigated for relatively large capillary number (up to 0.2). Finally, some simulations are performed to explain the phenomena of drop interaction in previous experiments, and some suggestions for future experiments are also provided.
