Study Design Clinical measurement. Objectives To translate the German version of the Exercise-Induced Leg Pain Questionnaire (EILP-G) to Greek and English and evaluate the psychometric properties of the Greek version. Background The EILP-G was developed to evaluate the severity of symptoms and sports ability in individuals with exercise-induced leg pain (EILP). Translation of the questionnaire to other languages will provide a standard outcome measure across populations. Methods The EILP-G questionnaire was cross-culturally adapted to Greek and English, according to established guidelines. The validity and reliability of the Greek version were assessed in 40 patients with EILP, 40 patients with other lower extremity injuries, 40 track-and-field athletes with no history of EILP, and 40 young adults without pathology. Participants completed the questionnaire at baseline and again after 7 to 10 days. Results The expert committee and the participants considered the questionnaire to have good face and content validity. Concurrent validity as assessed using the Schepsis score was almost perfect (rho = 0.947, P<.001). Dimensionality analysis revealed a 1-factor solution, explaining 83.8% of the total variance. Known group validity was demonstrated by significant differences between patients compared with the asymptomatic groups (P<.001). The Greek version exhibited excellent test-retest reliability (intraclass correlation coefficient = 0.995 for the EILP group) and internal consistency (Cronbach α = .942 for the EILP group). Finally, no ceiling or floor effects were found, as none of the individuals with EILP scored the maximum or minimum possible values on the questionnaire. Conclusion The Greek version, adapted from the original EILP-G, is a valid and reliable questionnaire, and its psychometric properties are comparable with the original version.

Abstract
Requirements for tribological protective coatings for medical tools, which would increase their wear and corrosion resistance, are very high. The presented paper deals with novel nano-composite, multilayer protective coatings for tissue interaction elaboration and their diagnosis on metallic substrates. A hybrid pulsed laser deposition system was used for coating deposition. In the presented work, nano-composite Cr/CrN + [Cr/a-C : H implanted by metallic nanocrystals] multilayer coatings were developed for surface protection. The mechanical properties of the coatings were investigated by means of micro-hardness and elasticity modulus measurements. Bio-medical tests were conducted using eukaryotic cells. Microstructural analysis by means of transmission electron microscopy indicated that chromium which was implanted into a-C : H layers reacted with carbon forming chromium carbides.
Numerical Analysis and Evaluation of Process and Geometry Specific Transient Temperature Fields for a New Variation of Gas-Assisted Injection Molding
Authors: Moritzer E. , Seidel S. 
Published: April 2015

Abstract
Two-Stage GITBlow, a special injection molding process developed by Polymer Processing Paderborn, combines the advantages of gas-assisted injection molding and blow molding. This is achieved by producing a preform with gas-assisted injection molding, which is then inflated into a larger cavity in the same mold. The inflation behavior is heavily influenced by the temperature distribution over the cross section of the preform. The preform is not rotationally symmetric and features functional geometries that are not inflated during the second process stage. Therefore, the temperature development during the first stage, i.e. the gas-assisted injection molding, as well as cooling and handling of the preform, is essential for the subsequent inflation. If certain thermal conditions are met, inflation and the creation of a homogeneous wall thickness is improved. The development of the necessary temperature profiles for homogeneous inflation is heavily dependent on the geometry of the gas chamber. Due to the preform's geometry, characteristic material accumulations are formed during the gas injection. These create local temperature hotspots that act as heat sources during the temperature equalization before inflation starts. Simulations were conducted to predict the gas chamber geometry and its influence on the temperature distribution and development during the process. The combination of two different simulation approaches creates a new method to analyze GITBlow and similar processes. Simulation results were verified with extensive experimental studies.

Experiences with windthrow in Canton Berne
The winter storms Vivian (1990) and Lothar (1999) hit Canton Berne with its many privately owned forests hard. The main objective of state intervention was to protect the forest areas that had remained intact. Important success factors in the management of the event were the strong attachment of owners to their forest, the swift and clear strategic response by the forestry service, rapid credit approvals by government and parliament, and further the high level of motivation and persistence of all actors involved. Ensuring an open, regular and objective communication in a comprehensible form for all target groups and during all phases of the process was also of great importance. Framework conditions change, such as legal regulations, the political environment, the situation of forest owners and enterprises or the timber market. These present new challenges for those in charge. A next storm will again come unexpectedly and will have other impacts than Vivian or Lothar. But as then, a successful management of the event will depend on the motivation of forest owners, clear strategies, a competent forestry service, the political will to support measures in forests and along the wood chain, together with a good collaborative relationship between all actors.
Mature Cystic Fibrosis Airway Neutrophils Suppress T Cell Function: Evidence for a Role of Arginase 1 but Not Programmed Death-Ligand 1

Published: April 2015

AbstractBacteria colonize cystic fibrosis (CF) airways, and although T cells with appropriate Ag specificity are present in draining lymph nodes, they are conspicuously absent from the lumen. To account for this absence, we hypothesized that polymorphonuclear neutrophils (PMNs), recruited massively into the CF airway lumen and actively exocytosing primary granules, also suppress T cell function therein. Programmed death–ligand 1 (PD-L1), which exerts T cell suppression at a late step, was expressed bimodally on CF airway PMNs, delineating PD-L1hi and PD-L1lo subsets, whereas healthy control (HC) airway PMNs were uniformly PD-L1hi. Blood PMNs incubated in CF airway fluid lost PD-L1 over time; in coculture, Ab blockade of PD-L1 failed to inhibit the suppression of T cell proliferation by CF airway PMNs. In contrast with PD-L1, arginase 1 (Arg1), which exerts T cell suppression at an early step, was uniformly high on CF and HC airway PMNs. However, arginase activity was high in CF airway fluid and minimal in HC airway fluid, consistent with the fact that Arg1 activation requires primary granule exocytosis, which occurs in CF, but not HC, airway PMNs. In addition, Arg1 expression on CF airway PMNs correlated negatively with lung function and positively with arginase activity in CF airway fluid. Finally, combined treatment with arginase inhibitor and arginine rescued the suppression of T cell proliferation by CF airway fluid. Thus, Arg1 and PD-L1 are dynamically modulated upon PMN migration into human airways, and, Arg1, but not PD-L1, contributes to early PMN-driven T cell suppression in CF, likely hampering resolution of infection and inflammation.
Simulation of Acoustic Behavior of Bubbly Liquids with Hybrid Lattice Boltzmann and Homogeneous Equilibrium Models
Authors: Chen Xiao-Peng , Liu Ming 
Published: April 2015

AbstractHomogeneous equilibrium model (HEM) has been widely used in cavitating flow simulations. The major feature of this model is that a single equation of state (EOS) is proposed to describe the thermal behavior of bubbly liquid, where both kinematic and thermal equilibrium is assumed between two phases. In this paper, the HEM was coupled with multi-relaxation-time lattice Boltzmann model (MRT-LBM) and the acoustic behavior was simulated. Two approaches were applied alternatively: adjusting speed of sound (Buick, J. Phys. A, 2006, 39:13807-13815) and setting real gas EOS. Both approaches result in high accuracy in acoustic speed predictions for different void (gas) volume of fractions. It is demonstrated that LBM could be successfully applied as a Navier-Stokes equation solver for industrial applications. However, further dissipation and dispersion analysis shows that Shan-Chen type approaches of LBM are deficient, especially in large wave-number region.
Computational Modeling of Membrane Viscosity of Red Blood Cells
Authors: Gounley John , Peng Yan 
Published: April 2015

AbstractDespite its demonstrated importance in the deformation and dynamics of red blood cells, membrane viscosity has not received the same attention in computational models as elasticity and bending stiffness. Recent experiments on red blood cells indicated a power law response due to membrane viscosity. This is potentially much different from the solid viscoelastic models, such as Kelvin-Voigt and standard linear solid (SLS), currently used in computation to describe this aspect of the membrane. Within the context of a framework based on lattice Boltzmann and immersed boundary methods, we introduce SLS and power law models for membrane viscosity. We compare how the Kelvin-Voigt (as approximated by SLS) and power law models alter the deformation and dynamics of a spherical capsule in shear flows.
Lattice Boltzmann Schemes with Relative Velocities
Authors: Dubois François , Fevrier Tony , Graille Benjamin 
Published: April 2015

AbstractIn this contribution, a new class of lattice Boltzmann schemes is introduced and studied. These schemes are presented in a framework that generalizes the multiple relaxation times method of d’Humières. They extend also the Geier’s cascaded method. The relaxation phase takes place in a moving frame involving a set of moments depending on a given relative velocity field. We establish with the Taylor expansion method that the equivalent partial differential equations are identical to the ones obtained with the multiple relaxation times method up to the second order accuracy. The method is then performed to derive the equivalent equations up to third order accuracy.
How does psychological safety affects employee turnover?
Authors: Staub Selva , Yener Serdar 
Published: April 2015

The issue of employee turnover in a school setting can signal the difference between a stable and
effective environment and an unstable, unhealthy learning environment. The challenge of turnover
may prove particularly vexing in private schools as it results in costly efforts to replace qualified
teachers, in addition to the potentially negative impression it creates among tuition-paying
clientele. Educational leaders have attempted to mitigate turnover rates and improve morale by
attempting the implementation of a Distributed Leadership framework in their administration of
the school. However, this may not always prove successful. The research carried out in this study
indicates that an additional layer of complexity should be taken into consideration when analyzing
the school’s organizational culture, that is Psychological Safety. It has been identified as taking on
the role of a mediator variant between Distributed Leadership and Turnover Intention.The primary aim of this study was to analyze and explain the mediation effect of psychological
safety on the relationship between distributed leadership and turnover intention within seven
private secondary schools in Turkey. The data were collected via survey; respondents consisted of
326 principals, vice-principals, and teachers.
Participants in this session will examine the combined effects of Distributed Leadership and
Psychological Safety relevant to employee turnover in an educational environment. Outcomes of
this session include understanding of mechanisms to assess the perceived level of Psychological
Safety, as well as tools to address sentiments of insufficient Psychological Safety among staff.

El anónimo autor del manuscrito latino Theophrastus redivivus, de la segunda mitad del siglo XVII, sostiene la tesis de la eternidad del mundo frente a los partidarios del creacionismo, inspirados en Moisés. Después de señalar las contradicciones internas del Génesis y su contraste con el Eclesiastés, hace un exhaustivo recorrido histórico sobre las diferentes opiniones de los filósofos grecolatinos acerca de si el mundo ha tenido un origen o no, decantándose a favor de la tesis de la eternidad del mundo, de acuerdo con el aristotelismo renacentista en la vía de Pomponazzi.
Freshly Thawed and Continuously Cultured Human Bone Marrow-Derived Mesenchymal Stromal Cells Comparably Ameliorate Allergic Airways Inflammation in Immunocompetent Mice

AbstractRecent data suggest that freshly thawed previously frozen mesenchymal stromal cells (MSCs) may not have the same effectiveness or breadth of anti-inflammatory activities as do continuously cultured MSCs. This has significant implications for clinical use, in which many infusion schemes use frozen cells thawed at the bedside for administration. The available data, however, predominantly evaluate in vitro MSC properties, and so far there has been limited in vivo analysis. To further assess this issue, we compared freshly thawed (thawed) versus continuously cultured (fresh) human bone marrow-derived MSC (hMSC) administration in a mouse model of mixed Th2/Th17 allergic airway inflammation induced by Aspergillus hyphal extract (AHE) exposures in immunocompetent C57Bl/6 mice. Control cell populations included fresh versus thawed murine bone marrow-derived MSCs (mMSCs) and human lung fibroblasts (HLFs). Systemic administration of both thawed and fresh hMSCs and mMSCs, but not HLFs, at the onset of antigen challenge in previously sensitized mice significantly ameliorated the AHE-provoked increases in airway hyper-reactivity, lung inflammation, and antigen-specific CD4 T-cell Th2 and Th17 phenotype. Notably, there was no difference in effects of fresh versus thawed hMSCs or mMSCs on any outcome measured except for some variability in the effects on the bronchoalveolar lavage fluid composition. These results demonstrated potent xenogeneic effects of human MSCs in an immunocompetent mouse model of allergic airways inflammation and that thawed MSCs are as effective as fresh MSCs. The question of fresh versus thawed MSC effectiveness needs to be investigated carefully and may differ in different in vivo disease-specific models.SignificanceThis study addressed whether freshly thawed mesenchymal stromal cells (MSCs) are as effective in in vivo settings as those that have been continuously cultured. It also provided further data demonstrating that xenogeneic use of MSCs in immunocompetent mice is as effective as murine MSCs. This information provides further support and direction for potential clinical use of MSCs in patients with severe asthma.
Continuous Monitoring of Turbidity and Conductivity in Wastewater Networks

Published: April 2015

Continuous monitoring of the sanitation network of the urban catchment of Pau (southwest France) has been performed since March 2012 using rain gauges, flowmeters, as well as turbidity and conductivity probes. Good correlations were obtained between turbidity, total suspended solids (TSS) and chemical oxygen demand (COD) on the one hand, and conductivity and total nitrogen on the other hand. This allowed an instantaneous and continuous estimation of pollutant concentrations and fluxes since that date. In the present paper we focused on the results of October 2012, which was characterized by alternating periods of dry and rainy events. Turbidity and conductivity raw data show different trends during the study period depending on the parameter and the rain events. A turbidity peak is observed at the beginning of each rain event but its amplitude varies with the intensity of the rain and the length of the preceding dry weather period. Conversely, conductivity decrease during each rain event implying, that rain water acts as a dilution factor. The behaviour of COD and total nitrogen differ markedly due to their partitioning between the dissolved (total nitrogen) and particulate phases (COD). Daily pollutant fluxes allow a global comprehension and monitoring of the sewer system. Important COD fluxes during a rain event preceded by a long dry weather period highlight the importance of erosion of sedimentary deposits in the sewerage network. During these events, important fluxes are discharged into receiving water leading to the question of the impact on aquatic life. Generally, these results highlight the potential of online monitoring to better understand the behaviour of the sewer network on long or short time scales. This could be a useful tool to manage wastewater treatment.
La figura di Cristo nelle nuove credenze religiose contemporanee
Authors: Fuss Michael 
Published: April 2015

La figura di Cristo, cuore della fede cristiana, è esplosa in postmodernità in nuove e strane cristologie, alternative alla Chiesa e in competizione con lei. Catturato nella mistico-esoterica galassia New Age, la figura di Cristo è vista ora come quella della gnostico-cosmica Sofia , ora come il Messia che porta una nuova rivelazione, ora come il Principio interior di guarigione integrale e integrazione universale, ora come la Leggenda fantastica e populista che ritiene confusi ricorsi magici. Sulla figura religiosa e storica di Cristo stanno tutti i tipi di alegorizanti interpretazioni, come quella che lo vede come il ricercatore ed il maestro della saggezza salvatrice . L’atteggiamento della Chiesa nei confronti di tali cristologie mobili è quello di capire come espressione di una cultura disorientata e, in dialogo conloro e in ricupero di suoi punti di luce, offrirne la “diakonia della verità” circa il Cristo della grande tradizione apostolica.
O sufismo e a acolhida da diversidade religiosa
Authors: Teixeira Faustino 
Published: April 2015

Um dos mais admiráveis traços da tradição mística islâmica, conhecida como sufismo (tasawwuf), é sua abertura inter-religiosa. O que mais encanta os que se acercam dessa tradição é o toque de interioridade, a fragrância de cortesia e a delicadeza espiritual. Exemplos significativos dessa abertura podem ser vislumbrados desde o século IX, com místicos como al-Hallâj, executado em Bagdá no ano de 922. Esse espírito de abertura irradia-se por outros grandes pensadores dessa tradição como Ibn ‘Arabi de Murcia (1165-1240) e Jalâl-od-Dîn Rûmî (1207-1273). As diversificadas crenças do universo são percebidas, com alegria, como palavras vinculadas ao hálito do Todo Misericordioso. São como ramos de uma única Fonte.
Keeping workers safe: Does provision of personal protective equipment match supervisor risk perceptions?
Authors: Clouser Jessica M. , Swanberg Jennifer E. , Bundy Henry 
Published: April 2015

BackgroundAlthough farm management may understand agriculture's risks, they may not provide personal protective equipment (PPE). This study describes thoroughbred farm management's risk perceptions, provision of PPE, and factors that influence its provision.MethodsThirty‐five representatives from 26 farms participated in a 1–4hr semi‐structured interview covering perceived risks associated with horse work and perspectives and provision of PPE. Interviews were audio‐recorded, transcribed, entered into ATLAS.ti, and analyzed by three coders.ResultsManagement cited horse‐related tasks as most dangerous, yet horse‐related PPE as least provided because of 1) differences in farm context, 2) the belief that workers were most important agents in their safety, 3) lack of confidence in its effectiveness, and 4) the perception that risk could never be eliminated.ConclusionsPPE provision was limited by management's poor perceptions of its efficacy relative to other factors. Future research should explore workers' perceptions and PPE's effectiveness in averting horse‐related injury. Am. J. Ind. Med. 58:886–896, 2015. © 2015 Wiley Periodicals, Inc.

ABSTRACTOdontocete echolocation clicks are generated by pneumatically driven phonic lips within the nasal passage, and propagated through specialized structures within the forehead. This study investigated the highly derived echolocation structures of the pygmy (Kogia breviceps) and dwarf (K.sima) sperm whales through careful dissections (N = 18K.breviceps, 6K.sima) and histological examinations (N = 5K.breviceps). This study is the first to show that the entire kogiid sound production and transmission pathway is acted upon by complex facial muscles (likely derivations of them.maxillonasolabialis). Muscles appear capable of tensing and separating the solitary pair of phonic lips, which would control echolocation click frequencies. The phonic lips are enveloped by the “vocal cap,” a morphologically complex, connective tissue structure unique to kogiids. Extensive facial muscles appear to control the position of this structure and its spatial relationship to the phonic lips. The vocal cap's numerous air crypts suggest that it may reflect sounds. Muscles encircling the connective tissue case that surrounds the spermaceti organ may change its shape and/or internal pressure. These actions may influence the acoustic energy transmitted from the phonic lips, through this lipid body, to the melon. Facial and rostral muscles act upon the length of the melon, suggesting that the sound “beam” can be focused as it travels through the melon and into the environment. This study suggests that the kogiid echolocation system is highly tunable. Future acoustic studies are required to test these hypotheses and gain further insight into the kogiid echolocation system.
