Knowledge Transfer from Detailed 3-D CFD Codes to System Simulation Tools – CCV Modeling in SI Engine
Authors: Vítek Oldřich , Macek Jan , Poetsch Christoph , Tatschl Reinhard 
Published: June 2016

Abstract
The paper deals with CCV knowledge transfer from reference data (either experiments or 3-D CFD data) into system simulation SW tools (based on 0-D/1-D CFD). It was verified that CCV phenomenon can be modeled by means of combustion model perturbations. The proposed methodology consists of two major steps. First, individual cycle data have to be matched with the 0-D/1-D model, i.e., combustion model parameters are varied to achieve the best possible match of in-cylinder pressure traces. Second, the combustion model parameters (obtained in previous step) are statistically evaluated to obtain PDFs and cross-correlations. Then such information is imposed to the 0-D/1-D tool to mimic pressure traces CCV. Good correspondence with the reference data is achieved only if both PDFs and cross-correlations are imposed simultaneously.
Different engine operating points were evaluated to draw some general conclusions in terms of CCV. It was confirmed that turbulence properties and initial flame kernel development are the dominant factors. However, these factors are neither independent nor random – they seem to be correlated. Operating points with high CCV are more organized in terms of the statistics – they exhibit strong cross-correlations of combustion model parameters.
A Method for Measuring the Radiation Pattern of UHF RFID Transponders
Authors: Jankowski-Mihułowicz Piotr , Węglarski Mariusz 
Published: June 2016

AbstractThe operating principles of RFID antennas should be considered differently than it is applied in the classical theory of radio communication systems. The procedure of measuring the radiation pattern of antennas that could be applied to RFID transponders operating in the UHF band is seldom discussed correctly in the scientific literature. The problem consists in the variability of the RFID chip impedance that strongly influences measurement results. The authors propose the proper methodology for determining the radiation pattern with respect to an individual transponder as well as an electronically tagged object. The advantage of the solution consists in the possibility of using components of different measuring systems that are available in typical antenna laboratories. The proposed procedure is particularly important in terms of parameter validation - the identification efficiency and costs of an RFID system implementation can be evaluated properly only on the basis of real values of considered parameters.
Ecumenical aspirations in the past 25 years in the Evangelical Church A. C. in Romania as reflected in the work of the two church leaders: Christoph Klein and Hans Klein
Authors: Fröhlich Hans Bruno 
Published: June 2016

Abstract
The volume “Geistliche Leitbilder und Weggefährten – Betrachtungen” written by the former bishop D. Dr. Christoph Klein, released in March 2015 (Schiller Verlag Bonn – Hermannstadt) and inspired by the fact, that the former vice bishop Dr. Hans Klein is turning 75 in November this year (2015), led the author to write this article. It is about two church leading personalities: Christoph Klein (commissioned as Bishop of the Evangelical Church A. C. in Romania between 1990 – 2010) and Hans Klein (commissioned as Vice Bishop of the same church between 1994 – 2007), whose commitment for the relationship between the Evangelical Church A. C. and the other churches inside and outside the country is nothing but to be admired. Deeply ecumenically committed, these two personalities have become spiritual models not only for the author of this article but also for many others.
Climatic Fluctuations Reflected in Slope and Fluvial Systems of Polish Carpathians and their Foreland During Upper Quaternary
Authors: Starkel Leszek 
Published: June 2016

AbstractOn continents, besides lake and bogs, we observe non-continuous sedimentation where particular layers or whole members represent time intervals of various lengths separated by breaks of different origin. Both, fluvial and slope sediments or forms carry climatic signal. By analyzing sources of sediments, factors of transfer, duration of deposition we reconstruct climatic changes (mainly temperature, precipitations and circulation of water). We order the collected records after age and tracing longitudinal profiles of slopes and river valleys. The slopes and valley floors inform us about spatial differentiation of extreme climatic-hydrological events and on their reflection in degradation or aggradation. All this information sums up the records collected in various projects or commissions like IGCP-158 and GLOCOPH (Starkel ed. 1982–1996; Starkel et al. 2007), Climatostratigraphy of the Holocene of Polish territory (Starkel et al. 2013) as well INTIMATE (Starkel et al. 2015; Gębica et al. 2015). It may be concluded that fluctuations in temperature combined with expansion of permafrost were the leading factors in transformation of landscape of analyzed area of Southern Poland during last cold stage, which is in contrary to the Holocene, when variations in humidity especially in frequency of extreme events played a leading role. The continental records very well express the role of transitional phases.
The Historical Science Novel and the Narrative of an Emergent Scientific Discourse
Authors: Schaffeld Norbert 
Published: June 2016

AbstractThis paper offers an analysis of three historical science novels, John Banville’sKepler(1981), Tracy Chevalier’sRemarkable Creatures(2009), and Clare Dudman’sWegener’s Jigsaw(2003), to address a number of interrelated questions that cover, for example, specific features of the genre, the narrative mode employed as well as its epistemic advantage, and the fictional integration of an emergent scientific discourse. While Banville’sKeplerestablishes a close affinity between the mathematical, the aesthetic and the narrative form, Chevalier’s neo-Romantic novelRemarkable Creaturesmakes full use of alternating first-person narratives to highlight the exceptional friendship of the historical fossil hunters Mary Anning and Elizabeth Philpot at a time when palaeontology was about to become a scientific discipline. The third novel, Clare Dudman’s imagined autofictionWegener’s Jigsaw, uses an autodiegetic narrator and a device that I refer to as ‘mentor-mentee constellation’ to facilitate a narrative transmission which guarantees that Alfred Wegener and his continental drift theory will find favour with the readership when he falls victim to oppressive scientific discourse.
Patient and Parent-Reported Signs and Symptoms for Group A Streptococcal Pharyngitis
Authors: Lindgren Christina , Neuman Mark I. , Monuteaux Michael C. , Mandl Kenneth D. , Fine Andrew M. 
Published: June 2016

BACKGROUND AND OBJECTIVES:
Identifying symptomatic patients who are at low risk for group A streptococcal (GAS) pharyngitis could reduce unnecessary visits and antibiotic use. The accuracy with which patients and parents report signs and symptoms of GAS has not been studied. Our objectives were to measure agreement between patient or parent and physician-reported signs and symptoms of GAS and to evaluate the performance of a modified Centor score, based on patient or parent and physician reports, for identifying patients at low risk for GAS pharyngitis.

METHODS:
Children 3 to 21 years old presenting to a single tertiary care emergency department between October 2013 and January 2015 were included if they complained of a sore throat and were tested for GAS. Patients or parents and physicians completed surveys assessing signs and symptoms to determine a modified age-adjusted Centor score for GAS. We evaluated the overall agreement and κ between patient or parent and physician-reported signs and symptoms and compared the performance of the scores based on assessments by patients or parents and physicians and the risk of GAS.

RESULTS:
Of 320 patients enrolled, 107 (33%) tested GAS positive. Agreement was higher for symptoms (fever [agreement = 82%, κ = 0.64] and cough [72%, 0.45]) than for signs (exudate [80%, 0.41] and tender cervical nodes [73%, 0.18]). Agreement was highest when no signs and symptoms contained in the Centor score were present (94%, κ = 0.61). The proportion of patients testing GAS positive rose as the modified Centor score increased.

CONCLUSIONS:
For identifying GAS pharyngitis, patients or parents and physicians showed moderate to substantial agreement for 3 of 4 key pharyngitis signs and symptoms.

Authors: Martínez-Ramos Marisol , Arroyo-Cosultchi Gabriel , Mandujano María C. , Golubov Jordan 
Published: June 2016

El género Mammillaria es de los más diversificados dentro de la familia Cactaceae, México es su centro de diversificación, y los estudios que analicen detalladamente los ciclos de vida de especies pertenecientes a este género son necesarios para determinar el estado de sus poblaciones y planear estrategias de conservación. Mammillaria humboldtii (C. Ehrenb, L.) es una especie endémica de Hidalgo, actualmente se encuentra en la categoría de “amenazada” por la NOM-059-SEMARNAT-2010 y en “peligro crítico” por la UICN. Empleamos modelos de proyección matricial para evaluar el estado de conservación de una población de M. humboldtii dentro de la Reserva de la Biosfera Barranca de Metztitlán, durante dos años (2012-2013). Se construyó una matriz de transición para poder calcular la tasa de crecimiento poblacional (?); se simularon los cambios en los elementos de la matriz que corresponden a la permanencia de banco de semillas, transición de semilla a plántula y permanencia de adultos. La tasa de crecimiento poblacional ? es de 0.8044 (0.754-0.846) indicando que la población decrece un 20 %. El proceso demográfico al que ? es más sensible fue la estasis (S = 68.35 %), seguido del crecimiento (G = 18.09 %). El valor reproductivo más alto fue el de la categoría adulto 3, las simulaciones mostraron que al incrementar el establecimiento de plántulas y la permanencia de adultos aumenta el valor de ? > 1, estos procesos son los principales cuellos de botella de la dinámica y crecimiento poblacional. Cualquier estrategia de manejo para la conservación de esta especie in situ deberá considerar el monitoreo a largo plazo de la población así como asegurar el establecimiento de plántulas y sobrevivencia de los adultos.
Intervención contra la violencia de género desde una perspectiva feminista: mujer y terapeuta

<p>En este artículo se pretende hacer patente el doble rol de muchas mujeres terapeutas,</p><p>que cada día disfrutamos, desde el feminismo, del ejercicio de nuestra profesión. Realizando nuestro trabajo como psicólogas no podemos olvidarnos, de que también somos mujeres. Así, si lo consideramos oportuno, no dudamos en acudir a nuestra experiencia como mujer para empatizar con otra mujer que demanda asistencia. Como es evidente, este doble rol nos posiciona en una situación privilegiada, permitiéndonos aplicar los conocimientos científicos, que indudablemente poseemos, con la mayor naturalidad, y sin ningún esfuerzo extra por nuestra parte, a la hora de entender una realidad, realidad que quizá también en algún momento haya sido la nuestra. Porque todas nosotras, antes de elegir ser terapeutas, inevitablemente fuimos mujeres. Al respecto, ADAVAS, asociación a la que pertenezco, me ofrece la posibilidad de<br />ejercer libremente mi profesión, siendo consciente su junta directiva, de mis procedimientos basados, además de en la Ciencia, en la cercanía y en el trato cálido, positivo y afable hacia las víctimas que demandan nuestro servicio.</p><p> </p><p>In this article we would like to focus on the double role that lots of therapeutic women have and enjoy everyday, from the feminism, in the practice of our profession.

Las mujeres y la producción textil en la Roma Antigua
Authors: Medina Quintana Silvia 
Published: June 2016

En las sociedades antiguas una de las principales ocupaciones de las mujeres eran los trabajos textiles, tanto desde un punto de vista socioeconómico como simbólico. Los autores antiguos reflejan y favorecen la idea de una mujer virtuosa trabajando en el telar o hilando, imagen muy presente también en la cultura romana. Sin embargo, la epigrafía nos ofrece una visión menos idealizada, pues nos informa de los oficios ejercidos por<br />mujeres de carne y hueso, sobre todo esclavas y personas de condición humilde en la mayoría de los casos.<br /><br />In Ancient societies, textile labour was one of the main occupations for women, both from a socioeconomic and symbolic point of view. The idea of a virtuous woman spinning or working at a loom is illustrated and supported in the texts of the ancient authors, also a very frequent image in Roman culture. Nevertheless, epigraphic evidence<br />shows a less idealized picture, as it reveals real-life women who were in most cases slaves or from low class condition.<br />

Al rescate de Franco y del franquismo: el hispanismo mexicano en la encrucijada de la Segunda Guerra Mundial
Authors: Sola Ayape Carlos 
Published: June 2016

<p>En 1945, y una vez terminada la segunda guerra mundial, los países vencedores –México, entre ellos– identificaron al régimen franquista como un saldo de guerra y, entre otras medidas en contra, se prohibió el ingreso de España en las Naciones Unidas. En defensa propia, y con un Franco acorralado, los arquitectos del franquismo diseñaron un plan estratégico para aguantar los embates del exterior, contando para ello con la ayuda de hispanistas mexicanos como Alfonso Junco o Jesús Guisa y Azevedo. Así, y teniendo en cuenta los perfiles de esta encrucijada histórica, el objetivo del presente artículo es analizar el discurso del hispanismo mexicano, concebido instrumentalmente para salir en defensa de Franco y del franquismo.</p><p> </p><p><strong> </strong></p>
El carácter multidimensional de la acción colectiva y los movimientos sociales: una problematización teórica
Authors: Kuri Pineda Edith 
Published: June 2016

<p>El presente artículo tiene como propósito fundamental dialogar entre diversas corrientes teóricas que han abordado el tema de la acción colectiva y los movimientos sociales. Así, serán revisados algunos de los preceptos básicos de la teoría de movilización de recursos; la sociología accionalista de Alain Touraine y Alberto Melucci; la teoría del enmarcado y finalmente la Escuela de la Subalternidad. Como veremos a lo largo de este trabajo, pese a que dichos enfoques comparten el reconocimiento de la racionalidad como un componente distintivo de la acción colectiva, mantienen notables diferencias en la forma de concebir un fenómeno sociopolítico que cuenta con varias dimensiones empíricas y analíticas.</p><p> </p>
