Cultural adaptation and reliability of the ISTAP Skin Tear Classification System to Chilean Spanish
Authors: Hevia Heidi , Ríos Lily , Bailey Christine , LeBlanc Kimberly , Santos Vera Lucia Conceição de Gouveia
Published: May 2021

Objective:

The International Skin Tear Advisory Panel (ISTAP) created the ISTAP Skin Tear Classification System with the aim of promoting a common and universal language to describe, classify and document skin tears, and increase awareness of the high prevalence of these wounds. Although there is a Spanish version of the ISTAP Skin Tear Classification System, the authors considered it relevant to have a specific Chilean Spanish version. The aim was to achieve the cultural adaptation of the ISTAP Skin Tear Classification System to Chilean Spanish, and verify its content validity and inter-rater reliability.

Method:

The study consisted of two phases: cultural adaptation of the ISTAP Skin Tear Classification System into Chilean Spanish, and validation of the culturally adapted system. A convenience sample of 150 health professionals classified 30 photographs of skin tears, using the same photographs used in the original ISTAP skin tear classification and validation study. Additionally, the clinical application of the classification system was tested among 20 nurses, who assessed and classified the skin tears (n=24) of hospitalised patients. For analysis of the inter-rater reliability, Fleiss' kappa was used.

Results:

The differences found in the translation referred to a synonym of the terms ‘skin’ or ‘cutaneous’, and the terms ‘flap’ or ‘tear’. Once analysed and discussed, the term ‘desgarro’ was maintained, which is the translation of the English term ‘flap’. There is no equivalent term for ‘skin tears’ in Spanish, but consensus was reached by researchers and collaborators to use the phrase: ‘desgarro de piel’. Once a consensus was reached on the wording for the translation, back-translation was completed and compared with the original English version and reviewed by the original author of the classification for accuracy. The content validity of the translated version of the ISTAP Skin Tear Classification System into Chilean Spanish showed a moderate agreement for the non-specialised nurses' group (0.4804) and for the specialised nurses' group (0.5308). Inter-rater reliability was achieved by obtaining a moderate agreement (Fleiss' kappa=0.53) and an almost perfect level of agreement for clinical application (Fleiss' kappa=0.83).

Conclusion:

The reported content validity and inter-rater reliability support the applicability of the cultural adaptation of the ISTAP Skin Tear Classification System to Chilean Spanish into practice.
Die Prototypensemantik als Möglichkeit der fremdsprachen- didaktischen Lexikographie.
Authors: Pichler Anna Malena
Published: May 2021

It has often been criticized that Learners’ Dictionaries lack a theoretical basis in linguistic theory. Prototype semantics are able to provide a solution to this problem in the context of cognitive linguistics. This article proposes a new approach to pedagogical lexicography based on the fundamental ideas of prototype semantics. In the framework of a culture-based dictionary for German as a Foreign Language (Kulturwörterbuch Deutsch als Fremdsprache), which is implemented as a students’ project at the department for German as a Foreign Language of TU Berlin, the model of a prototype-based semantic explanation is presented.
La percepció de la parla i la parla dels infants
Authors: Ester Subias Glòria
Published: May 2021

Els infants de 2-3 anys, encara no alfabetitzats, solen produir una parla que es considera que presenta característiques diferenciadores respecte del model adult que senten.S’han analitzat els factors que intervenen entre percepció i producció de la parla en interacció  infant-mestra en una mostra de 617 paraules, per conèixer si els processos de simplificació fonològica establerts per a aquesta edat, són la causa de les “errades”, o més aviat són degudes a l’acomodació de l’infant al reproduir el model que percep.El resultat de l’anàlisi en correlació infants-mestres ha demostrat un alt grau de coincidència en les produccions dels dos i per tant es va concloure que les errades no van ser a causa d’un desenvolupament fonològic deficient, atès que eren infants amb capacitats cognitives i comunicatives adequades, sinó a processos de simplificació fonològica que responien a les característiques pròpies de la parla espontània.
Aspectes ètics de l’ús de mesures de contenció coercitiva en l’entorn educatiu
Authors: Puigardeu-Aramendia Oscar
Published: May 2021

INTRODUCCIÓ. En els centres educatius es produeixen situacions en què alumnes amb dificultats de regulació de la conducta pateixen episodis d’agitació deguts a frustracions, conflictes entre iguals o incapacitat per acceptar els límits, entre altres motius. En algunes ocasions aquests episodis generen situacions de risc per al mateix alumne o per als seus companys i companyes o per a altres membres de la comunitat educativa. MÈTODE. S’analitzen diversos documents legislatius, normatius, de referència i d’experts des d’una perspectiva teoricoconceptual i crítica. RESULTATS. Els docents han de respondre a situacions de risc associades a episodis d’agitació de l’alumnat de manera ràpida, eficaç i segura. Les estratègies de contenció de l’alumnat són diverses i poden anar des de les contencions verbals i d’acompanyament emocional fins a intervencions en què sigui necessari restringir temporalment els moviments de l’alumne. DISCUSSIÓ. Les contencions coercitives en l’entorn escolar generen diversos neguits en els docents, ja que suposen una contradicció respecte dels principis de beneficència i autonomia. L’excepcionalitat i els riscos que implica l’ús de mesures de contenció coercitiva en els centres educatius obliga a una reflexió ètica sobre la necessitat, els procediments i les condicions de la seva utilització.

Implantación de la metodología de clase invertida en la asignatura “Marco Jurídico Profesional de la Actividad Física y el Deporte”. Implicaciones en la percepción, motivación y resultados académicos de los estudiantes
Authors: Mendaña Cuervo Cristina , González Fernández Anselma
Published: May 2021

En este trabajo se describe la implementación de la metodología Flipped Classroom en la asignatura “Marco Jurídico Profesional de la Actividad Física y el Deporte”, del Grado en Ciencias de Actividad Física y el Deporte, como respuesta al incremento en el bajo rendimiento de los alumnos desde la implantación del Grado. El objetivo metodológico ha sido potenciar el aprendizaje activo y colaborativo propio del nuevo rol del docente y del estudiante dentro del Espacio Europeo de Educación Superior (EEES). Conscientes de la necesidad de llevar a cabo un proceso de evaluación de las consecuencias que dicho cambio puede suponer en los alumnos, en este trabajo también se describe el estudio acerca de las expectativas y la predisposición que dicha metodología ha suscitado en los estudiantes (antes y tras la experiencia) y las consecuencias obtenidas, tanto en relación a la motivación del alumnado hacia la asignatura, como en la repercusión en los resultados académicos.Como principales conclusiones se pueden mencionar las siguientes. En primer lugar, en relación a la valoración de los alumnos y su posterior opinión sobre la metodología, cabe señalar que la experiencia práctica ha mejorado las expectativas que los alumnos tenían a priori, habiendo sido evaluadas con un instrumento ad hoc previamente validado.En segundo lugar, en relación a la motivación y los resultados académicos obtenidos por los estudiantes, la comparación realizada entre alumnos de dos grupos (experimental y control) ha puesto de manifiesto que, si bien el grupo experimental ha incrementado ambos factores, no ha sido estadísticamente significativo.
Pupil function design for multifocal confocal, STED, and isoSTED microscopy
Authors: Lee Dong-Ryoung , Bewersdorf Joerg
Published: May 2021

Point scanning super-resolution microscopy techniques such as stimulated emission depletion (STED) microscopy are powerful tools to observe biological samples at sub-diffraction limited resolution in three dimensions. However, scanning the sample with only a single beam limits the imaging speed in these microscopes. Here, we propose a concept to increase this speed by introducing highly flexible multifocal illumination and detection. We introduce phase patterns in the objectives’ pupil planes to create arrays of foci in the sample plane with negligible loss of laser power. High uniformity of these foci’s intensities is achieved by iteratively applying a weighted Gerchberg–Saxton phase retrieval algorithm. We characterize the performance of this iterative approach numerically and present simulation results that demonstrate the high quality of the focus arrays for future implementations in laser-scanning STED and isoSTED microscopes. The same approach can also be applied in diffraction-limited confocal laser scanning microscopy.

Published: May 2021

We present a modular implementation of structured illumination microscopy (SIM) that is fast, largely self-contained and that can be added onto existing fluorescence microscopes. Our strategy, which we call HIT-SIM, can theoretically deliver well over 50 super-resolved images per second and is readily compatible with existing acquisition software packages. We provide a full technical package consisting of schematics, a list of components and an alignment scheme that provides detailed specifications and assembly instructions. We illustrate the performance of the instrument by imaging optically large samples containing sequence-specifically stained DNA fragments.

Light scattering has been used for label-free cell detection. The angular light scattering patterns from the cells are unique to them based on the cell size, nucleus size, number of mitochondria, and cell surface roughness. The patterns collected from the cells can then be classified based on different image characteristics. We have also developed a machine learning (ML) method to classify these cell light scattering patterns. As a case study we have used this light scattering technique integrated with the machine learning to analyze staurosporine-treated SH-SY5Y neuroblastoma cells and compare them to non-treated control cells. Experimental results show that the ML technique can provide a classification accuracy (treated versus non-treated) of over 90%. The predicted percentage of the treated cells in a mixed solution is within 5% of the reference (ground-truth) value and the technique has the potential to be a viable method for real-time detection and diagnosis.

Published: May 2021

This paper describes the detailed characterization of a novel InP-Si3N4 dual laser module with results revealing relative intensity noise (RIN) as low as −165 dB/Hz and wide wavelength tunability (100 nm). The hybrid coupled laser is deployed in an unamplified 28 GBd 8 level pulse amplitude modulation (PAM) short-reach data center (DC) transmission system. System performance, which is experimentally evaluated in terms of received signal bit error ratio (BER), demonstrates the ability of the proposed laser module to support PAM-8 transmission across a 100 nm tuning range with less than 1 dB variance in receiver sensitivity over the operating wavelength range. Comparative performance studies not only indicate that the proposed source can outperform a commercial external cavity laser (ECL) in an intensity modulation/direct detection (IM/DD) link but also highlight the critical impact of RIN in the design of advanced modulation short-reach systems.

Published: May 2021

The monitoring of infrared thermal images is reported to analyze changes in skin temperature in the hand fingers when repetitive work is performed to know which finger has a greater risk of injury, besides, the recovery time is analyzed regarding the initial temperature and its relationship with age, sex, weight, height if practice sports, and Body Mass Index (BMI) per individual. For the above, an experimental test was carried out for 10 minutes on a repetitive operation that takes place in the telecommunications industry and 39 subjects participated in which an infrared thermal image of the dorsal and palmar part of both hands was taken in periods of 5 minutes after the 10-minute test has elapsed. The results show that none of the participants recovered their initial temperature after 10 minutes of the experimental test. In addition, it was found that there is a relationship between skin temperature and sex, and that age influences the recovery of temperature. On the other hand, the thumb, index, and middle fingers have a higher risk of injury in the analyzed task. It is concluded that performing repetitive work with all the fingers of the hand does not show that all they have the same risk of injury, besides that, not all the variables studied affect the recovery of temperature and its behavior.

El autor discurre acerca de la importantísima contribución de Michele Taruffo a la renovación del procesalismo convencional y del bagaje teórico de los profesionales de la jurisdicción, mediante la incorporación a la cultura dominante en tales medios del imprescindible conocimiento de la dimensión epistémica subyacente y tradicionalmente sofocada por la propiamente jurídica.
Los anteojos de Taruffo: una concepción de la jurisdicción
Authors: Aramburo C. Maximiliano A.
Published: May 2021

Toda la concepción de Michele Taruffo sobre la prueba judicial —que es la parte de su obra más conocida— toma su punto de partida en una idea de jurisdicción y de juez que le es metodológicamente funcional. La jurisdicción, de esa forma, está condicionada culturalmente en un modelo que determina las formas del proceso y condiciona el fondo de la decisión misma. En este artículo se exploran las bases fundamentales de la concepción de la jurisdicción que subyace a las nociones de decisión judicial y de prueba de la obra de Taruffo, examinando la idea general de cómo es el juez y el papel que desarrolla (es decir: aplicar el derecho), así como describiendo a rasgos generales el modelo burocrático de administración de justicia en el que opera.
Giuliani: Proceso y racionalidad. La relación jurídica procesal «dialéctica»
Authors: Negri Nicolás Jorge
Published: May 2021

De acuerdo con las exigencias actuales del Estado de Derecho constitucional y democrático, el estudio del proceso judicial exige una consideración especial en los aspectos lógicos y racionales del procedimiento, de modo tal que las prácticas forenses se correspondan con la naturaleza más profunda y propia de la relación jurídica procesal. Alessandro Giuliani nos muestra, con bases científicas e históricas, que desde sus orígenes antiguos y medievales, junto con los últimos aportes de la dogmática moderna, el proceso tradicional tiene una naturaleza verdaderamente dialéctica, que él mismo denomina como «controversia», que se corresponde con el modo en que interactúan las partes y el tribunal, y que tiene –a la vez– una fuerte interrelación con la ética y la política.
Portable magnetic levitation technologies
Authors: Alseed M. Munzer , Rahmani Dabbagh Sajjad , Zhao Peng , Ozcan Oguzhan , Tasoglu Savas
Published: May 2021

Magnetic levitation (MagLev) is a density-based method which uses magnets and a paramagnetic medium to suspend multiple objects simultaneously as a result of an equilibrium between gravitational, buoyancy, and magnetic forces acting on the particle. Early MagLev setups were bulky with a need for optical or fluorescence microscopes for imaging, confining portability, and accessibility. Here, we review design criteria and the most recent end-applications of portable smartphone-based and self-contained MagLev setups for density-based sorting and analysis of microparticles. Additionally, we review the most recent end applications of those setups, including disease diagnosis, cell sorting and characterization, protein detection, and point-of-care testing.
Pediatric reference intervals for endocrine markers and fertility hormones in healthy children and adolescents on the Siemens Healthineers Atellica immunoassay system
Authors: Bohn Mary Kathryn , Horn Paul , League Donna , Steele Paul , Hall Alexandra , Adeli Khosrow
Published: May 2021

Objectives

Rapid development in childhood and adolescence combined with lack of immunoassay standardization necessitates the establishment of age-, sex-, and assay-specific reference intervals for immunochemical markers. This study established reference intervals for 11 immunoassays on the new Siemens Healthineers Atellica® IM Analyzer in the healthy CALIPER cohort.

Methods

A total of 600 healthy participants (birth to 18 years) were recruited from the community, and serum samples were collected with informed consent. After sample analysis, age- and sex-specific differences were assessed, and outliers were removed. Reference intervals were established using the robust method (40–<120 participants) or nonparametric method (≥120 participants).

Results

Of the 11 immunoassays studied, nine required age partitioning (i.e., dehydroepiandrosterone-sulfate, estradiol, ferritin, folate, follicle-stimulating hormone, luteinizing hormone, progesterone, testosterone, vitamin B12), and seven required sex partitioning. Free thyroxine and thyroid-stimulating hormone demonstrated no significant age- and/or sex-specific differences.

Conclusions

Overall, the age- and sex-specific trends observed closely mirrored those previously reported by CALIPER on other platforms as well as other internationally recognized studies. However, established lower and upper limits demonstrated some discrepancies between published values from healthy cohorts on alternate analytical systems, highlighting differences between manufacturers and the need for platform-specific reference intervals for informed pediatric clinical decision-making.
Polyhedral oligomeric silsesquioxane (POSS)-modified phenolic resin: Synthesis and anti-oxidation properties
Authors: Wang Bing , Shi Minxian , Ding Jie , Huang Zhixiong
Published: May 2021

In this work, octamercapto polyhedral oligomeric silsesquioxane (POSS-8SH) and octaphenol polyhedral oligomeric silsesquioxane (POSS-8Phenol) were successfully synthetized. POSS-8Phenol was added into the synthesis process of liquid thermoset phenolic resin (PR) to obtain POSS-modified phenolic resin (POSS-PR). Chemical structures of POSS-8SH, POSS-8Phenol, and POSS-PR were confirmed by FTIR and 1H-NMR. TG and DTG analysis under different atmosphere showed that char yield of POSS-PR at 1,000°C increased from 58.6% to 65.2% in N2, which in air increased from 2.3% to 26.9% at 700°C. The maximum pyrolysis temperature in air increased from 543°C to 680°C, which meant better anti-oxidation properties. XRD results confirmed both POSS-8Phenol and POSS-PR-generated crystalline SiO2 in air, which could explain the improvement of anti-oxidation properties. SEM showed that the POSS-PR had phase separation during curing process. Finally, carbon fiber fabric-reinforced POSS-PR (C-POSS-PR) was prepared to verify the anti-oxidation properties of POSS-PR.
A green method for the preparation of phoxim based on high-boiling nitrite
Authors: Dong Changzan , Qiao Jinwen , Zhu Hongwei , Qian Guang , Zhu Jie , He Yupeng
Published: May 2021

Phoxim is a significant insecticide, and its current synthesis method has some shortcomings such as the high risk of explosion and the trans structure (main impurity) is hard to control. Our work solved the above disadvantages by introducing macromolecular alcohol (benzyl alcohol, etc.) as the starting material and optimizing the intermediate reaction conditions. Compared with the current synthesis route, the synthetic method has the following advantages: (1) intermediate benzyl nitrite has a high boiling point and strong safety; (2) intermediate α-cyanobenzaldehyde oxime sodium are almost (≥99%) cis structure, and no further refinement was required, which greatly reduced the amount of waste water produced; and (3) The high yield of phoxim was maintained at 72.9%.
Adjustment models for multivariate geodetic time series with vector-autoregressive errors
Authors: Kargoll Boris , Dorndorf Alexander , Omidalizarandi Mohammad , Paffenholz Jens-André , Alkhatib Hamza
Published: May 2021

In this contribution, a vector-autoregressive (VAR) process with multivariate t-distributed random deviations is incorporated into the Gauss-Helmert model (GHM), resulting in an innovative adjustment model. This model is versatile since it allows for a wide range of functional models, unknown forms of auto- and cross-correlations, and outlier patterns. Subsequently, a computationally convenient iteratively reweighted least squares method based on an expectation maximization algorithm is derived in order to estimate the parameters of the functional model, the unknown coefficients of the VAR process, the cofactor matrix, and the degree of freedom of the t-distribution. The proposed method is validated in terms of its estimation bias and convergence behavior by means of a Monte Carlo simulation based on a GHM of a circle in two dimensions. The methodology is applied in two different fields of application within engineering geodesy: In the first scenario, the offset and linear drift of a noisy accelerometer are estimated based on a Gauss-Markov model with VAR and multivariate t-distributed errors, as a special case of the proposed GHM. In the second scenario real laser tracker measurements with outliers are adjusted to estimate the parameters of a sphere employing the proposed GHM with VAR and multivariate t-distributed errors. For both scenarios the estimated parameters of the fitted VAR model and multivariate t-distribution are analyzed for evidence of auto- or cross-correlations and deviation from a normal distribution regarding the measurement noise.
Bangla hate speech detection on social media using attention-based recurrent neural network
Authors: Das Amit Kumar , Al Asif Abdullah , Paul Anik , Hossain Md. Nur
Published: May 2021

Hate speech has spread more rapidly through the daily use of technology and, most notably, by sharing your opinions or feelings on social media in a negative aspect. Although numerous works have been carried out in detecting hate speeches in English, German, and other languages, very few works have been carried out in the context of the Bengali language. In contrast, millions of people communicate on social media in Bengali. The few existing works that have been carried out need improvements in both accuracy and interpretability. This article proposed encoder–decoder-based machine learning model, a popular tool in NLP, to classify user’s Bengali comments from Facebook pages. A dataset of 7,425 Bengali comments, consisting of seven distinct categories of hate speeches, was used to train and evaluate our model. For extracting and encoding local features from the comments, 1D convolutional layers were used. Finally, the attention mechanism, LSTM, and GRU-based decoders have been used for predicting hate speech categories. Among the three encoder–decoder algorithms, attention-based decoder obtained the best accuracy (77%).
“It’s a Whole Vibe”: testing evaluations of grammatical and ungrammatical AAE on Twitter
Authors: Holliday Nicole , Tano Marie
Published: May 2021

This study focuses on listener perceptions of African American English (AAE) on Twitter, examining both grammatical and ungrammatical usages, as well as how these perceptions may be affected by the race of the speaker and rater. We conducted an experimental survey designed to address the following questions: 1. Does avatar race affect perception of the grammaticality of AAE? 2. Are differences between grammatical and ungrammatical AAE discernible to naive raters of different races? 3. How are various social attributes evaluated for avatars of different races and different linguistic varieties? Results indicate that participants generally do not downgrade avatars who use grammatical AAE on ratings of grammaticality or personal characteristics. However, participants of all races disprefer ungrammatical uses of AAE, with black raters being especially sensitive to ungrammatical AAE. These findings have implications for sociolinguistics in that they demonstrate that participants across racial backgrounds may differentiate grammatical versus ungrammatical AAE online, and that contrary to expectations based on previous literature, AAE is not universally downgraded in these contexts. However, results also indicate that the use of AAE still negatively impacts listeners’ perceptions of speakers as educated, demonstrating that some widespread biases against AAE-speakers persist in an online context.
Clause Structure and Illocutionary Force in Medieval Gallo-Romance: Clitic Position in Old Occitan and Early Old French Sentential Coordination
Authors: Donaldson Bryan
Published: May 2021

This paper analyzes the position of object and adverbial clitic pronouns in coordinated affirmative verb-first declaratives introduced bye(t)“and” in Old Occitan and early Old French, a context in which clitics are variably preverbal or postverbal. An empirical study reveals that this variation is principled and reflects semantico-discursive properties in the same way in these two related and grammatically similar medieval Gallo-Romance varieties. On a theoretical level, I posit that preverbal clitics occur when conjunction occurs at the TP level, and postverbal clitics occur when conjunction occurs at the CP level, and that the choice of clause structure (TP vs. CP) for second conjunct clauses depends on illocutionary force, which in turn depends on discourse coherence relations and the semantics ofverba dicendi(verbs of utterance).

The undoped YVO4 and Ce3+-doped YVO4 single crystals have been successfully grown by the Czochralski method in a medium frequency induction furnace. The X-ray diffraction patterns testified that all samples exhibited the pure tetragonal YVO4 crystalline phase without any parasitic phases. The optical properties of Ce3+-doped YVO4 single crystals with different doping concentrations were investigated via a combination of absorption, emission, and excitation spectra. Dependence of luminescence and absorption intensity on Ce3+ doping concentration was discussed at different excitation wavelengths. The typical transitions of Ce3+ ions and the unusual intrinsic luminescent phenomena of

Epítetos e insultos de grupo en español: Sobre una ambigüedad y sus implicaciones sintáctico-semánticas
Authors: Saab Andrés , Orlando Eleonora
Published: May 2021

In this paper, we further elaborate on a syntactic ambiguity between slurs and epithets first noticed in Orlando, Eleonora & Andrés Saab. 2020b. A stereotype semantics for syntactically ambiguous slurs.Analytic Philosophy61(2). 101–129. Here, we discuss in detail the large theoretical implications of such an ambiguity both for the proper analysis of binominal constructions in Spanish (e.g.,el idiota de Juan) and for the way in which it is advisable to model the expressive content slurs and certain epithets (those deriving from slurs) have. As for the first aspect, we contend that mainstream approaches in terms of predicate inversion for binominal constructions cannot account for why slurs lose their predicative import when occurring as epithets in binominal environments. In consequence, we propose a new analysis for epithets both in simple occurrences and in binominal constructions. This analysis derives the above-mentioned ambiguity as a type of structural ambiguity, according to which certain slurs can occur in predicative and in non-predicative positions. When they occur as predicates, they have a mixed semantics (McCready, Eric. 2010. Varieties of conventional implicatures.Semantics & Pragmatics3. 1–57) reflected both in the truth-conditional and the expressive dimensions, but when they occur as epithets, the truth-conditional dimension is lost and only the expressive content survives. As for the second aspect, we defend a stereotype semantics, according to which stereotypes are modeled as Kratzerian modal bases (i.e., set of propositions) in virtue of which stigmatizing theories of human groups are reflected in a parallel, expressive dimension of meaning. This way of modeling some kinds of expressive contents explains how different slurs and epithets manage to communicate different theories about particular human groups, which are the target of derogation.
Der Einfluss von Humankapital auf die Kaufabsicht von Messeausstellern: Eine Analyse anhand einer Ausstellerbefragung auf der FachmesseBest of Events2018
Authors: Winnen Lothar , Rühle Alexander , Piepiorka Christine , Scherle Nicolai , Groß Jiny
Published: May 2021

Unter der Prämisse, dass das Humankapital ein entscheidender Faktor für die erneute Buchung einer Messe durch einen Aussteller ist, wurde im Januar 2018 eine Befragung von 129 Messeausstellern auf der FachmesseBest of Events(BoE) durchgeführt. Ziel war die Identifikation des Einflusses von Humankapital (u. a. Kompetenzen der Mitarbeiter) des Messeveranstalters auf den Messeerfolg. Auf Basis einer multiplen Regression zeigt sich, dass das Humankapital des Messeveranstalters (u. a. Beratungsqualität, Fachkompetenz, Problemlösungsfähigkeit der Mitarbeiter) signifikant mit der Wiederbesuchsabsicht des Ausstellers, d. h. der Absicht der erneuten Buchung von Ausstellungsflächen auf der BoE korreliert. Die Studie legt daher nahe, dass gut ausgebildetes und kompetentes Personal für den Messeerfolg entscheidend ist. Dies gilt der Studie nach für die Planungsphase, jedoch überraschenderweise hat das Humankapital in der Durchführungsphase keinen signifikanten Einfluss auf die Wiederbesuchsabsicht des Ausstellers. Hieraus lässt sich als Handlungsempfehlung für Veranstalter ableiten, dass ein vorhandenes Budget eher vermehrt in die Planungsphase zu investieren ist, da sich dies positiv auf die Wiederbesuchsabsicht auswirkt.
Strategic Positioning of the Farm Holiday’s Post-Pandemic Competitive Advantages: Fresh Air and Sunlight
Authors: Quendler Erika , Magnini Vincent P. , Driouech Noureddin
Published: May 2021

The farm holiday has the potential to rebound faster following the COVID-19 pandemic than many other forms of tourism. This potential is due to two elements that are abundant in the location of holiday farms: fresh air and sunlight. This conceptual paper synthesizes various streams of research that illustrate how fresh air and sunlight can improve both actual and perceived salutogenesis. This paper then offers a series of recommendations that farm stay venues can adopt in order to, explicitly and implicitly, infuse fresh air and sunshine elements in their marketing messages. Furthermore, there is potential in designing marketing messages for farm holidays that demand further research activities, continuous information and awareness raising.
Efecto de tratamientos pregerminativos en la emergencia de plántulas de Guaiacum sanctum L. (Zygophyllaceae)
Authors: Mex Villalobos María Margarita , Carballo Hernández José Ignacio , González Lazo Edith , Uribe San Miguel Julian Alberto , Dzib Castillo Benito Bernardo
Published: May 2021

En México se encuentra la especie guayacán (Guaiacum sanctum L.), la cual se encuentra registrada como especie amenazada dentro de la Convención Internacional para Comercio de Especies Amenazadas de Flora y Fauna (CITES), grupo II. Una problemática para su reproducción a partir de semillas es que requiere tratamientos pregerminativos si no se siembra después de la cosecha, ya que puede presentar dormancia fisiológica y disminución en su viabilidad. En consecuencia, el objetivo del presente trabajo fue identificar la emergencia de plántulas a partir de tratamientos pregerminativos en semillas. Los tratamientos fueron seis, con cuatro repeticiones; el diseño experimental fue completamente al azar. Los análisis estadísticos se realizaron utilizando una prueba de T con el software INFOSTAT. Los resultados mostraron que sí existen diferencias estadísticas (p < 0.0001) entre tratamientos. Se concluye que los mejores tratamientos pregerminativos fueron el de remojo en agua durante 24 horas y la inmersión en peróxido dehidrógeno diluido en agua (3 ml L-1) durante 15 minutos.

A LaAlO3 carrier was prepared via the sol-gel method, and a Ni/LaAlO3 catalyst was prepared via the homogeneous precipitation method; this catalyst was used for the catalytic pyrolysis of soybean straw for syngas (H2 + CO) production. The analysis of the raw materials (straw) was performed via elemental analysis and industrial analysis. The support and catalyst were characterized and analyzed by X-ray fluorescence spectroscopy, thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, and N2 adsorption-desorption isotherms. The results illustrated that the NiO was uniformly loaded on the LaAlO3 surface. Furthermore, the effects of the Ni loading amount, pyrolysis temperature, holding time, and calcination temperature on the performance of the catalyst were studied. The results showed that the catalyst had the highest increase in production and concentration of H2 and CO when the Ni loading was 10 wt%, the calcination temperature was 500 °C, the reaction temperature was 800 °C, and the holding time was 20 min. Compared with the pyrolysis of straw without a catalyst, the yield of H2 and CO increased from 85 mL/g and 125 mL/g to 238.5 mL/g and 255 mL/g, respectively, and the concentration of H2 and CO increased from 23.5 vol% and 29.4 vol% to 43.1 vol% and 41.9 vol%, respectively.

Permittivity and filtration properties of grout socks for rock bolt installations
Authors: Lam C. , Jefferis S.A.
Published: May 2021

Rock bolts are commonly used to stabilise slopes and underground excavations but their installation can sometimes be difficult in challenging grounds due to excessive leakage or washout of the grout. To manage these problems, tubular geotextile socks have been adopted in the industry but there has been a lack of research on their properties. To advance the understanding of sock behaviour, the water permittivity and filtration properties of two types of grout sock have been investigated in their unstretched state. From the permittivity tests, it is shown that water flow through these socks will be laminar and that using more than one layer in a setup can effectively reduce the flow velocity. Moreover, it has been shown that the effect of the tester should be considered in the analysis or else the permittivity of the geotextile could be underestimated. From the filtration tests, it is shown that both types of grout sock tested are effective in minimising grout loss and that the permittivity of the filter cake will be many orders of magnitude lower than that of the socks. The results also show that the water–cement ratio of the grout will be reduced as a result of the dewatering process.

Formaldehyde is extensively and commonly used in Department of Anatomy for preservation of biological specimens as well as cadavers. Formaldehyde being a noxious chemical, may cause respiratory health problems among 1st year medical students attending dissection periodically as a part of MBBS curriculum. The following study was planned to observe the effect of formaldehyde vapours on heart rate, blood pressure, percentage oxygen saturation (SpO2) and respiratory rate of 1st year medical students who are routinely exposed to formalin vapours periodically. Randomly selected fifty medical students [Mean (SD) age of 18.94 (0.65) years] were assessed within 1week of admission to college and re-examined at intervals of 1 month and 6 months. Data was entered in Microsoft Excel and was analysed using Epi Info software version 7. There was a decrease in heart rate, systolic blood pressure, SpO2 values and respiratory rate (on comparing values after 6 months with that of baseline values) but it was not statistically significant. But it may be statistically significate after 1 year of periodical exposure and it could also be due to lower quantity of formalin exposure owing to the proper ventilation of the dissection hall as per the MCI regulations. KEY WORDS: Formaldehyde, heat rate, blood pressure, SpO2, respiratory rate.

Published: May 2021

The purpose of this article is to assess the reliability of the particular solutions of electromechanical problems obtained in practice by grid methods using the open source software GMSH & GetDP. The paper considers the issues of validation of computer models for calculating the electromagnetic force (EMF) and torque (EMT) obtained in the GMSH & GetDP software package. The results of calculations and compares for electromagnet-ic devices for the TEAM 20 and TEAM 24 test problems from the Compumag international community problems package are presented. A comparative assessment of the obtained results with the test ones was carried out. The relative average deviation between the measured and calculated values is: 7.6 % for induction; 7.5 % for the electromagnetic torque; the maximum deviation in electromagnetic force does not exceed 3.4%. The efficiency of using the GMSH & GetDP software for solving magnetostatic problems in a three-dimensional setting is shown. The presented results will be used to form the verification and validation matrices in assessing the reliability of numerical models, as well as in the development of digital twins of electromechanical devices

Published: May 2021

The issues of developing a combined positioning device for the microtunnel boring machine control system are considered. A device combining laser and inertial methods of determining coordinates is proposed, which provides the possibility of determining the coordinates and spatial position of the tunneling shield during the construction of straight and curved tunnels by the pushing method. A method for connecting the positioning device with the microtunnel boring machine control system based on the RS-485 wired interface is proposed. A method for calculating coordinates has been developed that takes into account the rotation of the local coordinate system relative to the local geodetic coordinate system.
“Massenfertigung” mit Losgröße Eins

Losgröße Eins - die kosteneffiziente Herstellung von individualisierten, einzigartigen Produkten - war von Anfang an das Markenzeichen von Industrie 4.0.

Bei Busch-Jaeger in Lüdenscheid haben wir eine Produktionslinie aufgebaut, in der ein individualisiertes Endprodukt für die intelligente Raumsteuerung in der Gebäudeautomation versandfertig vom Band läuft. In weniger als einem Jahr wurden mehrere zehntausend Produkte nach individuellem Kundenauftrag gefertigt und ausgeliefert, und das Werk wurde mit dem Industrie 4.0 Award 2019 ausgezeichnet.

Im Hinblick auf die Anwendungsszenarien von Industrie 4.0 betreiben wir eine wandlungsfähige Fabrik, in der die Produktion auftragsgesteuert abläuft und tief in B2C- und B2B-Prozesse integriert ist, in der sich Materiallogistik selbst organisiert und in der menschliche Bediener leicht mit Maschinen interagieren können. Der Bau dieser Produktionslinie war nur durch einen fertigungsorientierten Front-End-Designprozess möglich, bei dem zunächst ein digitaler Zwilling der gesamten Produktionslinie in OPC UA definiert und erst dann die mechanische und elektrische Konstruktion gestartet wurde.

Um eine Fabrik auf diese Weise effizient zu gestalten, gibt es jedoch keine ausreichenden Standards und Werkzeuge für ein nahtloses digitales Engineering; plug-and-produce-fähige Maschinen können nicht einfach von der Stange bestellt werden; auch ist die Einhaltung höchster Qualitätsansprüche für einzigartige Produkte eine eigene Herausforderung. Darüber hinaus beginnen Kunden, eine Individualisierung zu fordern, die nicht allein durch Neukonfiguration bestehender Maschinenfähigkeiten erreicht werden kann, sondern die eine kontinuierliche Umgestaltung der laufenden Maschinen im Hinblick auf das erfordert, was wir eine " Evergreen Factory " nennen.

In diesem Papier stellen wir die Bausteine und besten Praktiken für die Planung, den Bau und den Betrieb einer solchen automatisierten Produktion in Losgröße Eins vor. Darüber hinaus zeigen wir die Lücken und Herausforderungen auf, mit denen Fabrikbetreiber, Maschinenbauer und Systemintegratoren gegen Ende des ersten Jahrzehnts von Industrie 4.0 noch immer konfrontiert werden. Wir schließen mit Erwartungen, wie diese Lücken geschlossen werden können, einschließlich der Rolle der Industrie 4.0 Verwaltungsschale.
