Authors: Thalau Janis , Uhlmann Eckhart , Muthulingam Arunan
Published: July 2021

Die stetige Weiterentwicklung von Abrichtwerkzeugen führt zu vermehrt neuartigen Formrollen. Jedoch sind die Wirkzusammenhänge der unterschiedlichen Abrichterspezifikationen auf den Abrichtprozess derzeit unzureichend untersucht worden. Dabei hat der Abrichtprozess einen wesentlichen Einfluss auf das gewünschte Schleifergebnis. In technologischen Untersuchungen soll daher das Einsatzpotenzial von neuartigen Voll-CVD-Formrollen analysiert werden.

 

The continuous development of dressing tools leads to an increase in new types of dressing rollers. However, the interaction between the various dresser specification and the dressing process has not yet been adequately investigated. The dressing process has a significant influence on the grinding result. It has already been shown that the use of full-CVD-dresser leads to a less tool wear. Therefore, the potential of the new full-CVD-dresser is to be analyzed in technological investigations.

Assessment of the influence of intensity of optical signal on the probability of erroneous data registration in a single-photon communication channel
Authors: Timofeev A. M.
Published: July 2021

When measuring low-power optical signals in single-photon communication channels, the receiving modules must ensure the minimum probability of erroneous data recording. In this regard, it is advisable to use photon counters. They are highly sensitive, but are characterized by data recording errors. The aim of the work was to determine the effect of intensity of optical signal on the probability of erroneous data recording in a single-photon communication channel with a receiving module based on a photon counter.

Based on the results of experimental studies, the dependences of the probability of erroneous registration of binary symbols «0» Perr 0 on the intensity of the optical signal J0 , used to transmit these symbols for various supply voltages of the avalanche photodetector U, were obtained. It was found that with an increase of intensity of the optical signal, the dependences Perr 0(J0) first decrease, reaching their lowest value, and then increase. The performed assessment showed that the lowest probability of erroneous registration the binary symbols «0» for the investigated communication channel is equal to 17,56 • 10-2 and corresponds to J0 = 52,41 • 10-2 rel. units and U = 52,54 V.

Authors: Vasileva Oksana Y.
Published: July 2021

The article is devoted to the problem brake power prediction at the feasibility study of inland ships design. The analysis of the existing methods of calculating the brake power is presented: based on the theory of ship traction calculations, based on the regressions of L. I. Fomkinsky, based on the use of the admiralty coefficient. The problems that arise when using the considered methods at the feasibility study of ship design. The results of calculations of the brake power and an assessment of the results obtained for a sample of ships are given, allowing conclusions to be drawn about the possible use of existing methods. A method is proposed for calculating the brake power of a ship using the relationship between the dimensionless quantities, which allow taking into account both experimental data and the physics of phenomena. It is shown that the proposed method, when used at the feasibility study of inland ships design, has a higher accuracy in comparison with the considered methods for calculating the brake power.

Published: July 2021

The solubility of triclocarban in ultrapure water and in several natural aqueous solutions is influenced by several environmental factors. In this study the variation of temperature, pH, ionic strength and concentration of the organic matter over the solubility of triclocarban was analysed. The results show that the solubility of triclocarban increases by increasing the contact time, longer than the time of equilibrium and the temperature. It is less influenced by the variations of pH and strongly influenced by the variation of ionic strength and by the natural organic matter into the studied aqueous matrices.
GMRT Observations of the Exoplanetary Systems τ Boötis and 55 Cancri
Authors: Narang Mayank , P. Manoj , Ishwara Chandra C. H.
Published: July 2021

We present archival Giant Metrewave Radio Telescope (GMRT) observations of two exoplanetary systems, τ Boötis, and 55 Cancri, at 610 MHz and 150 MHz, respectively. Theoretical models predict these systems to have some of the highest expected flux densities at radio wavelengths. Both τ Boötis and 55 Cancri have been previously observed at low frequency (∼30 MHz) with Low-Frequency Array. τ Boötis shows tentative signatures of circularly polarized emission at 30 MHz, while no emission was detected from 55 Cancri. We do not detect radio emission from both the systems, but the GMRT observations set 3σ upper limits of 0.6 mJy at 610 MHz for τ Boötis and 4.6 mJy at 150 MHz for 55 Cancri. The sensitivity achieved at 610 MHz in these observations is comparable to some of the deepest images of an exoplanet field.

We present a regional photometric analysis of asteroid (101955) Bennu, using image data from the MapCam color imager of the OSIRIS-REx Camera Suite (OCAMS). This analysis follows the previously reported global photometric analysis of Bennu, which found that Bennu’s roughness was difficult to photometrically model owing to unresolved surface variation. Here we find that, even with a high-resolution shape model (20 cm per facet) and automatic image registration (<1 pixel error), Bennu remains a challenging surface to photometrically model: neither a suite of empirical photometric models nor the physically motivated Hapke model were able to eliminate the scatter in the data due to pixel-scale variations. Nonetheless, the models improved on the global analysis by identifying regional variations in Bennu’s photometric response. A linear empirical model, when compared with independent measures of surface roughness and albedo, revealed correlations between those characteristics and phase slope. A regional Hapke analysis showed the same structure in its single-scattering albedo and asymmetry factors; although the Hapke parameters were loosely constrained, complicating interpretation of their spatial variation, the regional variation in relative parameter sensitivity also correlated with shallower phase slope, higher albedo, and less macroscopic roughness.

Published: July 2021

Since 2013, the olive landscapes have gradually degenerated due to the spread and establishment of Xylella fastidiosa subsp. pauca (hereafter Xf) in Apulia, southern Italy. From 2013 to 2019, a total of approximately 54,000 hectares of olive orchards in the south of this region have been seriously damaged, and their restoration will progressively regenerate the economic, social, cultural and environmental nonmarket benefits. Since there is a willingness to restore the affected landscape in the best interest of the local citizens, this research aims to predict their preference heterogeneity and willingness to pay (WTP) to improve this landscape and continue research and experimentation in relation to Olive Quick Decline Syndrome Disease by the bacterium. For this purpose, a choice experiment method is used. The social field survey includes a representative sample of 683 respondents in three major cities (Foggia, Bari and Lecce) of Apulia region. The results reveal that for the local citizens interviewed, the most appreciated olive landscape services are cultural heritage and aesthetic values. In addition, the findings revealed citizens’ positive appreciation of improving the damaged olive landscape, while respondents are not willing to pay a premium for research. The results show that the average value that Apulians are willing to pay for landscape restoration is about 5.7 million of € per year. Further, this research has implications for land use planners in the study area, which faces issues of harmful pathogen management and land revival.

It is established existence of ground and bound state solutions for Choquard equation considering concave-convex nonlinearities in the following form

   \begin{document}$ \begin{equation*} \begin{cases} -\Delta u +V(x) u = (I_\alpha* |u|^p)|u|^{p-2}u+ \lambda |u|^{q-2}u \, {\rm{\;in\;}}\, \mathbb{R}^N, \\ \ u\in H^1( \mathbb{R}^N) \end{cases} \end{equation*} $\end{document}

where \begin{document}$ \lambda > 0, N \geq 3, \alpha \in (0, N) $\end{document}. The potential \begin{document}$ V $\end{document} is a continuous function and \begin{document}$ I_\alpha $\end{document} denotes the standard Riesz potential. Assume also that \begin{document}$ 1 < q < 2 $\end{document}, \begin{document}$ 2_\alpha < p < 2^*_\alpha $\end{document} where \begin{document}$ 2_\alpha = (N+\alpha)/N $\end{document}, \begin{document}$ 2_\alpha = (N+\alpha)/(N-2) $\end{document}. Our main contribution is to consider a specific condition on the parameter \begin{document}$ \lambda > 0 $\end{document} taking into account the nonlinear Rayleigh quotient. More precisely, there exists \begin{document}$ \lambda^* > 0 $\end{document} such that our main problem admits at least two positive solutions for each \begin{document}$ \lambda \in (0, \lambda^*] $\end{document}. In order to do that we combine Nehari method with a fine analysis on the nonlinear Rayleigh quotient. The parameter \begin{document}$ \lambda^*> 0 $\end{document} is optimal in some sense which allow us to apply the Nehari method.
Heterogeneous discrete kinetic model and its diffusion limit
Authors: Kim Ho-Youn , Kim Yong-Jung , Lim Hyun-Jin
Published: July 2021

A revertible discrete velocity kinetic model is introduced when the environment is spatially heterogeneous. It is proved that the parabolic scale singular limit of the model exists and satisfies a new heterogeneous diffusion equation that depends on the diffusivity and the turning frequency together. An energy functional is introduced which takes into account spatial heterogeneity in the velocity field. The monotonicity of the energy functional is the key to obtain uniform estimates needed for the weak convergence proof. The Div-Curl lemma completes the strong convergence proof.

Published: July 2021

Objectives: The Indonesian government issued large-scale social restrictions (called Pembatasan Sosial Berskala Besar, or PSBB) at the beginning of the coronavirus disease 2019 (COVID-19) pandemic to control the spread of COVID-19 in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Greater Jakarta). Public compliance poses a challenge when implementing large-scale social restrictions, and various factors have contributed to public non-compliance with the regulation. This study aimed to determine the degree of non-compliance and identify the factors that contributed to public non-compliance with the PSBB in Greater Jakarta, Indonesia.Methods: This was a quantitative study with a cross-sectional design. A total of 839 residents of Greater Jakarta participated in this study. Data were collected online using a Google Form, and convenience sampling was undertaken. Univariate and multivariate analyses were performed to explore the relationships between public non-compliance with the PSBB regulation and socio-demographic variables, respondents’ opinion of the PSBB, and social capital.Results: A total of 22.6% of subjects reported participating in activities that did not comply with the PSBB. The variables that most affected non-compliance with the PSBB were age, gender, income, opinion of the PSBB, and social capital.Conclusions: Strengthening social capital and providing information about COVID-19 prevention measures, such as washing one’s hands with soap, wearing masks properly, and maintaining social distancing, is essential. Robust public understanding will foster trust and cooperation with regard to COVID-19 prevention efforts and provide a basis for mutual agreement regarding rules/penalties.

Published: July 2021

This manuscript introduces the designing and emulation of a wireless, intelligent health surveillance device based on the internet of medical things, with GSM alert technology by health caregivers. In hospitals or medical centers where the body temperature of the patient needs to be constantly checked or other vital signs have to be checked, this is normally achieved by a specialist or another paramedicine personnel by continuously checking the temperature, pulse rate and keeping records of these arguments. This approach is really repetitive and can be very tiring, especially in medical centers crowded with patients. The main system task is to surveillance the patient's body pulse rate and the patient's body temperature and sending the information to the specialists wirelessly via the liquid crystal display. The transmitting unit of this suggested system continuously surveillance the patient's body temperature, as well as the heart rate with digital sensors, and ultimately, displays the outcomes on the liquid crystal display transmitter to present to the specialists. The receiver device is placed in the specialist chamber for continuous wireless surveillance   of the patient's body temperature and heart rate. At the receiver end where the specialist will be, an alarm is often triggered and triggered When the patient's heart rate or temperature is below/above the normal human threshold of 37 ° C and 70 beats/min (bpm), then, send an SMS to the specialist if he or she is absent as a means of continuous update. The suggested framework was implemented utilizing Proteus Tools and programs, composed in Embedded C. The obtained outcomes indicate an effective way to relay details on duty to the specialists for urgent patient care.

1994 – « Oral Participation: A Question of Motivation? »
Authors: Thomas David
Published: July 2021

The teaching of ESP can be helped greatly by judicious use of sources of motivation which push the individual student to greater efforts in the learning of a foreign language. This article explores some of the psychological investigations into human motivation, based on cognitive theories and then attempts, using group dynamics, to put this knowledge to use in the classroom situation. Students are provided with a fixed objective, in the form of a pluridisiciplinary ECLANE (foreign language case study), in an attempt to increase active oral participation and to improve the level of acquisition of English for Specific Purposes.
2010 – « Comment susciter la prise de conscience phonologique de l’anglais : cas d’étudiants en formation LANSAD-sciences »
Authors: Chaplier Claire
Published: July 2021

Cet article vise à montrer que la transmission d’un message cohérent en anglais ne peut pas être réussie sans une prononciation intelligible. Pour ce faire, il convient de mettre en place une prise de conscience phonologique, avant tout entraînement à la phonétique et à la phonologie, dans le cadre d’une médiation avec l’enseignant et la participation active de l’étudiant.Cette recherche-action porte sur un groupe d’étudiants en formation LANSAD (LANgues pour Spécialistes d’Autres Disciplines)-sciences. Tout d’abord, la spécificité LANSAD-sciences sera présentée, puis seront définis le dispositif et les conditions de déclenchement de la prise de conscience phonologique (responsabilité, médiation) ainsi qu’une démarche théorique et pratique. Enfin, des applications par le biais d’enregistrements et de questionnaires seront analysées.
2014 - « Quelle grammaire pour le LANSAD ? De l’enseignement de la langue à l’apprentissage du discours : éléments pour l’acquisition de l’interaction verbale »
Authors: Rouveyrol Laurent
Published: July 2021

Ce travail traite du rapport que la grammaire peut/doit entretenir avec le public LANSAD. Nous partons du principe que ce qui doit désormais être acquis, c’est la capacité à interagir avec autrui, à argumenter, à agir sur les systèmes de valeur et les représentations : on passe de l’enseignement de la langue et de sa grammaire à l’acquisition du discours. Comment favoriser une telle acquisition ? La première étape consiste à étudier les débats authentiques pour déterminer quelles stratégies sont adoptées par les locuteurs natifs pour gérer les contraintes du genre ; nous prendrons le débat Question Time pour corpus. La deuxième étape a pour objet de faire prendre conscience aux apprenants de l’existence de ces stratégies, culturellement marquées. Nous nous demandons ensuite quel parcours didactique mettre en place. De façon plus large, il est question ici de déterminer l’apport de l’analyse de discours pour favoriser l’acquisition de certaines compétences langagières inhérentes à l’interaction sociale dans le monde contemporain.
2018 - « Lorsqu’Artémis rencontre Hermès : confiance et reliance mises à l’épreuve »
Authors: Puozzo Isabelle Capron
Published: July 2021

Le lien entre la confiance et la reliance offre des pistes innovantes et fertiles à explorer tant sur le plan conceptuel que sur celui empirique. Il permet, en effet, de porter un regard nouveau sur le thème, déjà bien connu, de la confiance en soi en explorant son rôle dans la capacité de l’individu à se relier à lui-même, mais aussi à se relier aux autres. De même, la notion de reliance soulève le débat de la confiance en l’autre, en son enseignant et en ses pairs. Cet article de fond vise ainsi à proposer une définition des concepts pour ensuite questionner les phénomènes entre la confiance et la reliance dans le contexte bien spécifique de l’apprentissage des langues.
2019 - « Apprendre un contenu disciplinaire en langue étrangère : enjeux politiques, théoriques et pratiques pour l'internationalisation des formations dans l'enseignement supérieur »
Authors: Roussel Stéphanie
Published: July 2021

L'internationalisation des formations revêt plusieurs formes. La mise en place de cours de nombreuses disciplines universitaires en langue étrangère en fait partie. Les raisons politiques (attractivité internationale, professionnalisation) sont claires et consensuelles. Mais la question essentielle reste de savoir si l'enseignement d'une discipline dans une langue étrangère est synonyme à la fois d'un meilleur apprentissage du contenu disciplinaire et de la langue étrangère. Un état de l'art du domaine et une réflexion sur les fondements théoriques de ces pratiques ont mené à la mise en place d'expérimentations contrôlées, qui permettent de mieux comprendre ce qui se joue sur le plan cognitif, lorsque la langue et le contenu disciplinaire doivent être appris simultanément. De ces résultats empiriques découlent certaines pistes d'aménagement didactique pour les cours en langue étrangère. Les enseignants de langues pour spécialistes d'autres disciplines ont alors un rôle important à jouer pour que ces pratiques participent à une internationalisation réussie.
La Dirección de Inteligencia de la Policía de la Provincia de Buenos Aires y el espionaje a la movilización indígena en 1992
Authors: Lenton Diana , Nagy Mariano
Published: July 2021

La Dirección de Inteligencia de la Policía de la Provincia de Buenos Aires (DIPPBA) fue creada en 1956 y disuelta en 1998. La DIPPBA orientó sus acciones a través de la articulación de una lógica de orden nacional, destinada a sostener la proscripción del peronismo, y otra de orden internacional, en relación con la Doctrina de la Seguridad Nacional y la creación del enemigo interno en el marco de la Guerra Fría. En este artículo analizamos el fondo documental de la DIPPBA para señalar la riqueza de esta fuente para la comprensión de las políticas de represión del movimiento indígena en la segunda mitad del siglo XX. En particular, enfocamos los registros producidos por las acciones de seguimiento e inteligencia respecto a los festejos y contrafestejos motivados por el V Centenario de la Conquista de América, en 1992. Se trata de legajos que reúnen información acerca de distintas acciones de inteligencia desplegadas en la provincia de Buenos Aires para espiar, especialmente, a quienes mostraban una postura crítica en relación con la llegada de Colón a América, pero también, sorprendentemente o no, a aquellos que reproducían el tono celebratorio de la efeméride. En efecto, la DIPPBA atribuía a las actividades y grupos observados la gestación de frentes opositores o revolucionarios con apoyo internacional vinculados al terrorismo. Observamos también la incomodidad que generan las organizaciones y los reclamos indígenas en tanto no responden al imaginario colectivo al que se los suele reducir.
La lengua de los tobas bolivianos en un vocabulario inédito del franciscano Hermán Cattunar (c. 1911)
Authors: Carpio María Belén , Mendoza Marcela
Published: July 2021

Mucho de lo que sabemos sobre la sociedad de los tobas del Chaco boliviano se encuentra en publicaciones de misioneros franciscanos que interactuaron con ellos en el siglo XIX. Exploradores y etnógrafos europeos publicaron breves descripciones etnográficas y anotaron palabras sueltas en lengua toba que resultan insuficientes para analizar su lengua. La falta de datos lingüísticos impide corroborar nuestra presunción acerca de vínculos culturales y sociales que históricamente habrían vinculado a los tobas bolivianos con los llamados tobas occidentales de Argentina. En este trabajo, sistematizamos los datos lingüísticos de un vocabulario toba inédito atribuido al franciscano Hermán Cattunar (c. 1911), atendiendo al contexto histórico de su producción. Presentamos la estructura del vocabulario y describimos, desde una perspectiva funcionalista, los pronombres libres, los índices pronominales verbales (Haspelmath 2013; Cysouw 2003), las estrategias de negación (Miestamo 2000, 2006), y los números cardinales registrados por Cattunar. Nuestro análisis contribuye al estudio de posibles procesos de gramaticalización entre lenguas guaycurúes, no detectables al estudiar cada lengua sincrónicamente, y proporciona materiales para investigar la hipótesis de contacto entre los tobas bolivianos y otros tobas de la región.

Crowdsourcing platforms have gained importance in recent times, and their success is dependent mainly on the participation of the crowd. Participation is a function of both intrinsic and extrinsic motivation. Moreover, with the growing scale of information, the participants would need to focus on the quality of information to achieve sustainable participation. Our study uses game elements and information quality grounded in Motivational Affordance Perspective (MAP) to study the intrinsic and extrinsic participation on a crowdsourcing platform. We collected responses from 337 participants who are actively contributing to any crowdsourcing platform. Warp PLS uses partial least square structured equation modeling. The results confirm that the use of game elements positively promotes the participant’s intrinsic and extrinsic participation. We also confirmed that motivation is also positively moderated by the quality of information that the crowdsourcing platform shares with the participants. The results help in extending the theoretical arguments of MAP and self-determination theory.
