Follow the Connections! Finding the Big Picture of Internet Communications
Authors: Maireder Axel 
Published: November 2014

Abstract
Many tools can be used to track down, store and comprehensively evaluate digital objects, things like how “buzz” develops and how “sentiments” are determined. This information can be used to develop a general evaluation of certain products or a schedule for releasing marketing material on these products. At the same time, the relevance of individual digital objects (e.g., tweets, blog posts and YouTube videos) and actors (e.g., individuals, media and organizations) frequently remains just as much of a mystery as the high-level networking and dynamics of the discussion do. It is the dynamics of these networks that most significantly contribute to the way that opinions are shaped on the Internet and determine whether videos go “viral” and discussions become “flame wars.” As part of the TANEP (Towards an Analytics of Networked Publics) project, the GfK Verein is funding research on methods that can bring these dynamics to visual life and, as a result, reflect the essence of the Internet as a network.The article demonstartes how information is gathered and what it can tell us.
Numerical Analysis of the Unsteady Propeller Performance in the Ship Wake Modified By Different Wake Improvement Devices
Authors: Bugalski Tomasz , Szantyr Jan A. 
Published: November 2014

Abstract
The paper presents the summary of results of the numerical analysis of the unsteady propeller performance in the non-uniform ship wake modified by the different wake improvement devices. This analysis is performed using the lifting surface program DUNCAN for unsteady propeller analysis. Te object of the analysis is a 7000 ton chemical tanker, for which four different types of the wake improvement devices have been designed: two vortex generators, a pre-swirl stator, and a boundary layer alignment device. These produced five different cases of the ship wake structure: the original hull and hull equipped alternatively with four wake improvement devices. Two different propellers were analyzed in these five wake fields, one being the original reference propeller P0 and the other - a specially designed, optimized propeller P3. Te analyzed parameters were the pictures of unsteady cavitation on propeller blades, harmonics of pressure pulses generated by the cavitating propellers in the selected points and the fluctuating bearing forces on the propeller shaft. Some of the calculated cavitation phenomena were confronted with the experimental. Te objective of the calculations was to demonstrate the differences in the calculated unsteady propeller performance resulting from the application of different wake improvement devices. Te analysis and discussion of the results, together with the appropriate conclusions, are included in the paper.

Authors: Qiao Dongsheng , Yan Jun , Ou Jinping 
Published: November 2014

Abstract
In the deepwater exploitation of oil and gas, replacing the polyester rope by a wire in the chain-wire-chain mooring line is proved to be fairly economic, but this may provoke some corresponding problems. Te aim of this paper is to compare the fatigue damage of two mooring system types, taking into account corrosion effects. Using a semi-submersible platform as the research object, two types of mooring systems of the similar static restoring stiffness were employed. Te mooring lines had the chain-wire-chain and chain-polyester-chain structure, respectively. Firstly, the numerical simulation model between the semi-submersible platform and its mooring system was built. Te time series of mooring line tension generated by each short-term sea state of South China Sea S4 area were calculated. Secondly, the rain flow counting method was employed to obtain the fatigue load spectrum. Thirdly, the Miner linear cumulative law model was used to compare the fatigue damage of the two mooring system types in long-term sea state. Finally, the corrosion effects from zero to twenty years were considered, and the comparison between the fatigue damage of the two mooring system types was recalculated.

CO2 doped γ-irradiated hydroxyapatite for EPR dosimetry
Authors: Ziaie Farhood 
Published: November 2014

Abstract
Synthetic nano-structure hydroxyapatite samples were doped by carbon in furnace via exposing to CO2 circulating gas in different time of 30, 120, and 360 min under 100°C and 400°C of temperatures. FTIR, TEM and XRD analyses results confirmed the doping of carbonate group to the hydroxyapatite structure. The samples were irradiated in absorbed doses of 2, 5, 10, 20, 50, and 80 kGy using a 60Co γ-ray source and subjected to EPR measurement, subsequently. The EPR signal intensities were constructed as a function of radiation dose, were compared with the results of raw sample and were studied from dosimetric point of view. The obtained results show a considerable increment in EPR signal intensities of the samples which were treated at 400°C. At the doses less than 20 kGy the carbon doped samples show a better EPR respond. This is much better for doses below 5 kGy in comparison to the raw samples and the response is quite linear.
Analysis of the flow instability among channels of the OTSG in the naval craft NPP
Authors: Su-xia Hou , Ji-jun Luo , Jun Xu , Jie-yu Liu 
Published: November 2014

Abstract
The instability occurring of the OTSG (Once-Through Steam Generator) in naval craft nuclear power plants is presented by the multivariable frequency domain theory. As concerning coupling interactions of the OTSG tubing, it is more accurate for analyzing the instability of OTSG compared to the common single variable method. A mathematical model for the system is derived from the fundamental equations by using the perturbation, Laplace-transform and the nodalization techniques. The stable boundary and parameters which influence the stability of the system are evaluated through computer simulation.
On an analytical evaluation of the flux and dominant eigenvalue problem for the steady state multi-group multi-layer neutron diffusion equation
Authors: Ceolin C. , Schramm M. , Bodmann B. E. J. , Vilhena M. T. , de Q. B.Leite S. 
Published: November 2014

Abstract
In this work the authors solved the steady state neutron diffusion equation for a multi-layer slab assuming the multi-group energy model. The method to solve the equation system is based on an expansion in Taylor Series resulting in an analytical expression. The results obtained can be used as initial condition for neutron space kinetics problems. The neutron scalar flux was expanded in a power series, and the coefficients were found by using the ordinary differential equation and the boundary and interface conditions. The effective multiplication factor k was evaluated using the power method. We divided the domain into several slabs to guarantee the convergence with a low truncation order. We present the formalism together with some numerical simulations.
Microstructural and Nanostructural FE-SEM, TEM, and STEM Investigations of High Strength Boron-Alloyed Steel Used in the Automotive Sector
Authors: Säglitz M. , Berger D. , Gernert U. , Selve S. 
Published: November 2014

Abstract
More and more steel grades with martensitic microstructure are used for highly stressed structural components in the automobile branch. They are used in the field of light weight construction and for crash safety. Principally, press-hardened boron-alloyed steels with low carbon content are used here. In this study, the fine microstructure is investigated by means of FE-SEM and TEM microscopy. Possibilities but also limits of the FE-SEM investigation methodology are clearly pointed out and demonstrated presenting concrete examples. In addition to that, further microstructural investigations are performed using a modern scanning transmission electron microscope (STEM). The device allowed for switching from the TEM mode to the SEM mode and thus enabled an investigation of one and the same microstructural section in SEM and TEM conditions; first experiences are presented.
Failure of Large High-strength Fasteners by Hydrogen Embrittlement
Authors: Neidel A. , Fischer B. , Ullrich Th. 
Published: November 2014

Abstract
Five out of several tens of large high-strength fasteners, used for attaching compressor-end supports of a large gas turbine engine in a test rig to its foundation, failed by deferred fracture after tensioning. The hexagonal bolt heads fractured off at the fillet of the shaft end. This happened in a delayed manner, in some cases six hours or so after tensioning. Because of this peculiar delayed fracture, hydrogen embrittlement (HE) was suspected as the metallurgical cause of failure. Delayed cracking is typical of and consistent with HE. On the fracture surfaces of the liberated hexagonal heads, some microfractographic fracture features, consistent with hydrogen embrittlement, were found.

Published: November 2014

Objective.In adults, osteoarthritis (OA) is associated with obesity and knee alignment. Whether knee alignment differences develop during childhood and are associated with obesity is unknown. We assessed the distribution of knee alignment in children and adolescents, and determined how knee alignment differs between obese and nonobese children.Methods.This cross-sectional study examined knee alignment in 155 healthy weight and 165 obese subjects. Knee alignment [metaphyseal-diaphyseal angle (MDA) and anterior tibiofemoral angle (ATFA)] and fat mass were measured using whole body dual-energy X-ray absorptiometry (DEXA). National reference data were used to generate age- and sex-specific body mass index (BMI, kg/m2) Z-scores. Multivariable linear regression was used to identify independent factors associated with ATFA and MDA.Results.The mean MDA and ATFA were similar between obese and nonobese subjects. In stratified analyses, females had greater variability in MDA and ATFA values (p < 0.001 and p = 0.04, respectively) at higher BMI Z-scores. Compared with healthy weight controls, obese subjects had less valgus of the MDA prior to the onset of puberty (+ 2.0°, p = 0.001), but had greater valgus at later pubertal stages (−1.9°, p = 0.01).Conclusion.We found significantly greater variability in knee alignment among females at higher BMI Z-scores, and greater valgus alignment in obese adolescents in late puberty. The major limitation is the use of DEXA for assessment of alignment, which needs validation against longstanding radiographs. Longitudinal studies are needed to determine whether childhood obesity is a risk factor for progressive malalignment that may predispose to pain and risk of early osteoarthritis.

Published: November 2014

Objective.To evaluate clinical factors associated with the absence of radiographic progression in patients with spondylitis.Methods.The cross-sectional study included 672 patients. All patients presented a disease evolution of more than 15 years. Patients were classified as with radiographic spinal involvement versus without radiographic spinal involvement. We included clinical variables potentially related to null radiological progression.Results.Seventy-five patients had no radiographic involvement. These patients were predominantly female, had a lower erythrocyte sedimentation rate (ESR), and a lower C-reactive protein level. Multivariate analysis showed an association with the female sex and low ESR.Conclusion.Clinical factors associated with this lack of progression were female sex and low ESR.

Published: November 2014

Objective.To assess the sensitivity of the Patient-Reported Outcomes Measurement Information System 29-item Health Profile (PROMIS-29) and the Functional Assessment of Chronic Illness Therapy-Dyspnea 10-item short form (FACIT-Dyspnea) for measuring change in health status and dyspnea in systemic sclerosis (SSc).Methods.One hundred patients with SSc completed the PROMIS-29, FACIT-Dyspnea, and traditional instruments [Medical Research Council Dyspnea Score, St. George’s Respiratory Questionnaire (SGRQ), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Medical Outcomes Study Short Form-36 (SF-36)] at baseline and 1-year visits. PROMIS-29, FACIT-Dyspnea, and traditional instrument change scores were compared across composite modified Medsger Disease Severity and modified Rodnan Skin score (mRSS) change groups.Results.Moderately high Spearman correlation coefficients were observed between FACIT-Dyspnea and SGRQ (r = 0.57), FACIT-Dyspnea functional limitations and SF-36 physical component summary (PCS; r = 0.51), PROMIS-29 physical functioning and HAQ-DI (r = 0.50), and SF-36 PCS (r = 0.52) change scores. In most validity comparisons, PROMIS-29, FACIT-Dyspnea, HAQ-DI, and SF-36 scores performed similarly. While PROMIS-29 covers more content areas than SF-36 (e.g., sleep), it may do so at the expense of responsiveness of its 4-item physical function scale as compared to the multiitem-derived SF-36 PCS. Statistically significant increases in SF-36 role physical (p = 0.01) and physical component scale (p = 0.016), but not PROMIS-29, were observed in patients with mRSS improvement.Conclusion.PROMIS-29 and FACIT-Dyspnea are valid instruments to measure health status and dyspnea in patients with SSc. In physical function assessment, longer PROMIS short forms or computer adaptive testing should be considered to improve responsiveness to the effect of skin disease changes on physical function in patients with SSc.

Published: November 2014

Objective.To describe the frequency and types of reported adverse events and system improvement recommendations in the Morbidity and Mortality Conference (M&MC) within the Division of Rheumatology at The Hospital for Sick Children, Toronto, Ontario, Canada (SickKids).Methods.A 5-year retrospective review of the M&MC within the Division of Rheumatology at SickKids was completed. Descriptive data including the number and types of events reported were collected. Events were categorized using an adaptation of the National Coordinating Council for Medication Error Reporting and Prevention Index. Recommendations were classified according to the Institute for Safe Medication Practices Canada.Results.Between January 2007 and December 2011, 30 regularly scheduled M&MC were held. Eighty-three cases were reviewed. The most common types of reported events were related to “miscommunication” (34.9%), “treatment/test/procedure” (22.9%), “adverse drug reactions” (12.0%), and “medication errors” (8.4%). Category A events (“an event that has the capacity to cause error”) were the most common with 39.8% of the cases, followed by Category C events (“an event occurred that reached the patient, but did not cause harm”) with 28.9%. Eighty-nine recommendations were made. Over half of these were classified as “information” (58.4%), followed by 11 “rules and policies” recommendations (12.4%). Of the 36 action items generated from these recommendations, most are either complete or ongoing.Conclusion.The M&MC within the Division of Rheumatology reviews a variety of events. Increased reporting of adverse events can lead to system improvements, and has the potential to improve and promote safer healthcare.

Published: November 2014

Objective.To determine the factors associated with severe radiographic hip involvement in patients with ankylosing spondylitis (AS).Methods.A cross-sectional retrospective study was performed. The patients were classified into 3 groups based on the Bath Ankylosing Spondylitis Radiology Hip Index (BASRI-hip): minimal hip disease, moderate hip disease, and severe hip disease. Demographic, clinical, radiographic, and laboratory data were collected and analyzed. To identify factors associated with severe hip disease, ordinal regression analyses were performed.Results.A total of 256 patients were involved in the study. There were differences in the age at onset, delay in diagnosis, bilateral hip involvement, sacroiliitis, Schober’s index, and occiput-to-wall distance among the 3 groups (p < 0.05). The patients with severe hip disease had lower C-reactive protein and erythrocyte sedimentation rate levels than did the minimal group (p < 0.05). The functional status based on the Bath Ankylosing Spondylitis Functional Index and the Harris Hip Score showed significant differences (p < 0.05). The results of the ordinal regression analyses showed that bilateral hip involvement, sacroiliitis, delay in diagnosis, age at onset, and spinal involvement were associated with a higher BASRI-hip (p < 0.05).Conclusion.Bilateral hip involvement, severe sacroiliitis, longer delay in diagnosis, early disease onset, and spinal involvement are associated with severe hip disease in patients with AS. The severity of hip involvement is associated with the functional status in AS.

Objective.We determined whether osteoprotegerin (OPG) concentrations are associated with established cardiovascular disease (CVD) among patients with rheumatoid arthritis (RA).Methods.OPG concentrations were measured by ELISA in 151 patients with RA (54 with CVD) and 62 age-matched control subjects without CVD. Established CVD was composed of documented ischemic heart disease, cerebrovascular disease, and peripheral artery disease.Results.In patients with RA, age, body mass index (BMI), rheumatoid factor (RF) positivity, anticyclic citrullinated peptide (anti-CCP) antibody positivity, and joint erosion status were associated with OPG concentrations [partial R (p) = 0.175 (0.03), −0.277 (0.0009), 0.323 (< 0.0001), 0.217 (0.008), and 0.159 (0.05), respectively]. Median (interquartile range) OPG concentrations increased from 6.38 (3.46–9.31) to 7.07 (5.04–10.65) and 8.64 (6.00–11.52) ng/ml in controls and patients with RA who had CVD and those who did not, respectively (p = 0.0002). Upon adjustment for age, sex, traditional risk factors, and BMI in mixed regression models, OPG concentrations remained lower in controls compared to patients with RA without CVD (p = 0.05) and in the latter compared to those with CVD (p = 0.03); the association of OPG concentrations with CVD among patients with RA also persisted after additional adjustment for RF and anti-CCP antibody positivity, and erosion status (p = 0.04).Conclusion.OPG concentrations are associated with disease severity and CVD prevalence in patients with RA. Whether consideration of OPG concentrations can improve CVD risk stratification in RA merits future longitudinal investigation.
De la transgression des lois du langage
Authors: Mieszkowski Jan , Forain Guillaume 
Published: November 2014

À travers la mise en scène des fantasmes héroïques et les controverses sur le sens de la loi quand c’est sur la scène de l’histoire que les individus doivent faire leur devoir, Le Prince de Hombourg prend la forme d’une série d’échecs à établir un langage où s’exprimeraient clairement les décisions, les responsabilités, et la loi. Sous le regard de Kleist, l’histoire invalide les postulats de la dramaturgie aristotélicienne, elle suspend la capacité à juger éthiquement des identités, des actes et des intentions. Elle confronte le langage de la loi à sa limite indépassable : celle d’un discours performatif qui déclare la loi, mais ne maîtrise pas les conditions de sa performativité.
Parménide. Recommencer le verbe être
Authors: Année Magali 
Published: November 2014

Fruit de la présentation orale du livre Parménide. Fragments, Poème, précédé de Énoncer le verbe être, Paris, Vrin, « Bibliothèque des textes philosophiques », 2012, cet article entend avant tout faire retour sur les intentions et la position qui sous-tendent l’approche résolument linguistique dont il s’agit. Mais en retraçant rapidement les différentes étapes du commentaire, il s’attache également à mettre en évidence le fil directeur qui les relie non seulement toutes entre elles, mais encore tout autant à la traduction des fragments qui découle d’elles. C’est ainsi que l’interprétation contenue dans certains passages particuliers de cette traduction (fr. 8, 4 / 32 / 42 ; fr. 6, 5 et 8-9 ; fr. 1, 31-32 ; fr. 19 ; fr. 8, 38 ; fr. 2, 3-5 et 6, 1), restée implicite dans le livre, se voit, ici, plus explicitement formulée.
Aristote, ses commentateurs et les déficiences délibératives de l'esclave et de la femme
Authors: Veloso Claudio William 
Published: November 2014

Cet article entend montrer que les « déficiences délibératives » qu’Aristote attribue à l’esclave (naturel) et à la femme en Pol. I 13, 1260a 4-15 et qui jouent un rôle explicatif important dans ce premier livre ne trouvent aucune justification théorique dans le corpus aristotélicien, que ce soit dans les ouvrages logico-métaphysiques, psycho-physiques ou éthico-politiques. En effet, il s’agit d’explications idéologiques, pseudoscientifiques, de la condition sociale inférieure de chacun de ces groupes. Ainsi, cet article veut aussi attirer l’attention sur une certaine tendance des commentateurs à chercher à tout prix des circonstances atténuantes pour les thèses d’Aristote en la matière, tendance qui, signe des temps, s’est sans doute aggravée ces dernières décennies et qui, dans des cas extrêmes, va jusqu’à qualifier de « défendable » la défense aristotélicienne de l’esclavage.
