Thermisch leitfähig modifizierte Funktionskunststoffe
Authors: Amesöder Simon , Ehrenstein Gottfried W. 
Published: February 2022

Abstract
Der Beitrag beschreibt das Potential und wesentliche Einflussgrößen von thermisch leitfähig modifizierten Thermoplasten, die als Funktionskunststoffe zur direkten Wärmezu- und -abfuhr beispielsweise im Spritzgießverfahren zu komplexen Bauteilen geformt bzw. darin lokal integriert werden können. Durch eine gezielte Zugabe sehr gut wärmeleitender metallischer bzw. keramischer Füllstoffe kann die Wärmeleitfähigkeit solcher gefüllter Kunststoffe deutlich verbessert werden. Um Wärmeleitfähigkeiten im technisch interessanten Maßstab zur erreichen, sind Füllstoffanteile von bis zu 60 Vol.-% notwendig. Entscheidende Einflussgrößen neben dem Füllgrad sind die Eigenleitfähigkeit und die Geometrie der Füllstoffpartikel. Durch anisotrope Partikel, wie z. B. plättchenförmiges Kupferpulver mit einem hohen Länge/Durchmesser-Verhältnis, lässt sich die Wärmeleitfähigkeit gegenüber kugeligen Partikeln deutlich verbessern. Verarbeitungsbedingte Orientierungen führen bei anisotroper Füllstoffgeometrie zu einer auch für die Praxis relevanten Vorzugsrichtung beim Transport der Wärme.
Alloying reactions in nanostructured multilayers during intense deformation
Authors: Perepezko John H. , Hebert Rainer J. 
Published: February 2022

Abstract
Under intense deformation of metallic multilayer samples, a nanometer-scale layer thickness and grain size develops during repeated cold-rolling. Along with the evolution of the highly refined microstructure, a nanoscale interfacial alloying occurs that can result in an amorphization reaction. The deformation of multilayers exhibits driven system behavior during alloying. As the length scale of the layer thickness converges to the length scale of the mixing zone during rolling, amorphization develops in appreciable volumes. The results from selected experiments demonstrate that the relative specific interfacial area is the key microstructural metric to describe the deformation-driven alloying.

Abstract
The effects of wet-milling mixtures of α-Fe2O3 and cobalt hydroxide Co(OH)2 over a range of Co/Fe ratios for 215 h have been investigated by neutron diffraction and Mössbauer spectroscopy. The starting materials were mixed according to the stoichiometric formula (Co

c = 0.04, 0.08 and 0.14 for the mixtures with the lowest Co content (x = 0.037, 0.071 and 0.133) and defect concentrations in the range y ≈ 0.1 –0.2. Both the spinel phase and un-reacted α-Fe2O3 are found to occur in the neutron diffraction patterns and Mössbauer spectra for the high Co content mixtures x = 0.234 and x = 0.380. Rietveld refinements of the neutron data indicate that the Co atoms predominantly occupy the octahedral B sites with vacancies also found to be located on the octahedral B sites. Analyses of the Mössbauer spectra of the milled samples confirm the existence of vacancy defects in the B sites and reveal that the vacancies cause similar effects to those of the Co ions, leading to a higher average charge state per iron atom.
A systematic study of motif pairs that may facilitate enhancer–promoter interactions
Authors: Wang Saidi , Hu Haiyan , Li Xiaoman 
Published: February 2022

Abstract
Pairs of interacting transcription factors (TFs) have previously been shown to bind to enhancers and promoters and contribute to their physical interactions. However, to date, we have limited knowledge about such TF pairs. To fill this void, we systematically studied the co-occurrence of TF-binding motifs in interacting enhancer–promoter (EP) pairs in seven human cell lines. We discovered 423 motif pairs that significantly co-occur in enhancers and promoters of interacting EP pairs. We demonstrated that these motif pairs are biologically meaningful and significantly enriched with motif pairs of known interacting TF pairs. We also showed that the identified motif pairs facilitated the discovery of the interacting EP pairs. The developed pipeline, EPmotifPair, together with the predicted motifs and motif pairs, is available at https://doi.org/10.6084/m9.figshare.14192000. Our study provides a comprehensive list of motif pairs that may contribute to EP physical interactions, which facilitate generating meaningful hypotheses for experimental validation.
Surprise questions in spoken French
Authors: Celle Agnès , Pélissier Maud 
Published: February 2022

Abstract
This paper offers a pragmatic account of two wh-questions in French used non-canonically - c’est quoi, ce N and qu’est-ce que constructions. It is claimed that in this non-canonical use, both constructions express surprise. As these constructions may be syntactically ambiguous between an information-seeking reading and a surprise reading, it is expected that the two readings differ in terms of prosody. This hypothesis is supported by the results of a production experiment. Experimental evidence shows significant prosodic differences between syntactically similar information-seeking questions and surprise questions. Surprise questions exhibit an increase in lengthening, slower speech rate and less frequent rising final contours.
Current Perspectives Concerning the Autonomy of Will while Concluding a Fixed-Term Employment Law Relationship
Authors: Zapletal Roman 
Published: February 2022

Abstract
The present text focuses on selected issues with regards to the private law principle of the autonomy of will and its manifestations within the area of labor law. More precisely, its limitations are analysed in the event of concluding an employment law relationship for a fixed term. The major restriction in the given context is seen in the requirement of one of the contracting parties to be procedurally active (while performing the respective juridical act) so that the anticipated legal consequences could be achieved. Firstly, the following paragraphs briefly deal with the general position of Czech labor law within the national regulation, in order to introduce the relevant legal context. Secondly, the main scope of the text represents limited analysis of a current fixed-term employment law relationship regulation from both the national (Czech) and supranational (EU) perspectives. Most importantly, the respective provisions arising out of applicable laws on the domestic level (the Czech Labor Code) have been confronted with those existing on the EU level (Directive 99/70/EC). Therefore, the desirable accordance of the former with the latter could be proven. As far as no less significant practical aspects are concerned, the final part points out actual challenges related to presupposed legal conversion of a fixed-term employment law relationship (based on the concluded employment contract) into an indefinite one. In the light of recent case law which will be mentioned, the conditions as prescribed in the Czech Labor Code are not interpreted unanimously, which naturally affects its application in practice in a more negative manner.

Objetivo: Identificar algunos aspectos relacionados con el estigma de personal asistencial hacia habitantes de calle consumidores de sustancias psicoactivas.
Metodologia: Para lograr este objetivo, se llevó a cabo un estudio cualitativo, con enfoque hermenéutico y de alcance descriptivo, mediante el análisis categorial de las transcripciones de las grabaciones de los discursos de dos grupos focales con 32 participantes, miembros del Sistema de Atención al Habitante de Calle Adulto de Medellín, Colombia. La sistematización y la codificación del análisis se hicieron en un archivo de Excel®, destacándose la emergencia de las categorías: “emociones”, “creencias” y “actitudes”.
Resultados: En los discursos de los participantes, se reiteran contenidos ambivalentes de los estigmas hacia esta población. Por una parte, la frustración en su trabajo, como principal emoción que coincide con las creencias de desconfianza y actitudes evasivas hacia ellos; y, por otro, los sentimientos de gratificación por la labor realizada, acordes con posturas más protectoras y pacientes durante el acompañamiento, pero que no se alejan de un ideal moralista de cero consumos.
Conclusión: Reconocer y discutir abiertamente sobre el estigma podría orientar otras formas más humanizadas en la labor con este tipo de población, en tanto se devela que el rol profesional no nos exime del prejuicio, el estereotipo y la discriminación

Aims of this study to determine the predisposing factors and common presenting complaints of ROCM patients, the knowledge of which will assist in formulation of effective preventive measures at our local level. A retrospective, hospital record-based study was conducted comprising 30 patients that presented to our tertiary care centre from 1st February to 31st July, 2021, admitted under a Multidisciplinary mucormycosis team. Detailed history and examination was supplemented with histopathological and radiological investigations. Preponderance for middle aged to elderly was seen. Only one patient had bilateral presentation. Diabetes mellitus was found to be the primary associated comorbidity. Duration of COVID infection emerged as a significant factor with 70% of cases observed to have a duration &#62; 28 days. Primary presenting complaint was facial edema followed by proptosis and Diminution of vision. Corticosteroid use was the prevailing predisposing factor. All patients received parenteral therapy with Amphotericin B. Of the 30 cases, 76.67% required primary functional endoscopic debridement, and four reported mortality as the final outcome. 10% patients required re-debridement with retrobulbar amphotericin B injection, and only two ended in Orbital exenteration. High index of clinical suspicion in elderly and diabetics especially in corticosteroids and/or oxygen therapy is required. Due attention to warning symptoms and signs, early diagnosis and apt treatment may help optimize the outcome of ROCM in the setting of COVID-19.

To assess the knowledge and awareness of glaucoma among nursing personnel in a rural tertiary care hospital. Questionnaire based study conducted on 106 nursing personnel. A self designed questionnaire combined of 20 closed ended dichotomous and open ended questions were administered. Subjects 'having heard of glaucoma' even before being recruited for the study were defined as aware and subjects who were having some understanding of the eye disease were defined as knowledgeable. A total of 106 subjects participated in the study. The proportion of awareness was 96.22% (102). ‘Good knowledge’ was demonstrated in 26.41% (28) of the participants. 44.3% (47) participants were classified under ‘fair knowledge’ and the remaining 29.24% (31) were deemed with ‘poor knowledge’. Even though the level of awareness of glaucoma among the nursing personnel is good, their knowledge base is still inadequate.

Published: February 2022

Cataract is one of the main causes of preventable childhood blindness. It can be either hereditary or non-hereditary. Paediatric cataracts are idiopathic in majority of cases. Major challenge in pediatric cataract is to overcome amblyopia. Early diagnosis and prompt treatment can result in good visual prognosis.In this case series, we present three siblings having congenital cataract. They presented to our hospital in their mid and late twenties for the cataract surgeries. Detailed examination of these cases were done and many other systemic abnormalities were detected along with ocular findings. Small incision cataract surgery under GVP under GA was done for all three cases.There was no history of congenital cataract in the family. one of the sibling younger brother did not have congenital cataract and other abnormalities. Early diagnosis and treatment avoids long-term adverse sequalae like strabismus and amblyopia. Late presentation, cataract surgery can be done and we can accept visual outcome as shown in these cases. Visual rehabilitation with adequate compliance can have a benefit in improving visual acuity and binocularity.Even though early surgical intervention is mandatory to have adequate visual outcome, nevertheless visual rehabilitation can also be expected in congenital cataracts with late presentation as seen in these cases.
Efectos colaterales del COVID-19: el cuidado del adulto mayor en el hogar
Authors: Matassini Silvana 
Published: February 2022

Este articulo busca explorar los efectos colaterales del COVID-19 en relación al cuidado de la población adulta mayor asegurada al seguro social del Perú y que se encontraban confinadas en sus hogares. Se realizó un estudio de caso sobre el efecto de la pandemia en personas adultas mayores que solían asistir a un centro de atención al adulto mayor (CAM). Se llevaron a cabo entrevistas semi estructuradas vía telefónica a los participantes. El estudio mostró que la pandemia ha ocasionado ciertas reconfiguraciones en los hogares de las personas adultas mayores, tanto en su materialidad como en las dinámicas internas.
Las PAM que participaron en el estudio recibieron el apoyo y cuidado de sus familiares más cercanos, por lo general los que compartían el mismo hogar. Sin embargo, las debilidades en el sistema de salud y en trabajos de protección social podrían vulnerar a aquellas personas adultas mayores con redes de apoyo menos robustas. Los efectos colaterales de la pandemia más resaltantes en la PAM, están relacionados a sus actividades recreativas, ya que han quedado paralizadas, ocasionándoles sentimientos de frustración y aburrimiento. La actual pandemia aun exige un cuidado y seguridad constante que evite poner en riesgo de contagio a la población en general pero que también considere dentro de sus estrategias de cuidado el efecto de la salud a causa de la reducción de sociabilidad. El trabajo conjunto entre el asegurado, familias y EsSalud, garantizará mejores estrategias de prevención y atención
Las personas mayores durante la Pandemia COVID-19: políticas públicas y acceso a las tecnologías de la información y comunicación en Argentina

Published: February 2022

Las personas mayores se encuentran insertas en una sociedad caracterizada por la aceleración tecnológica, la comunicación y la información. Estas transformaciones cambian a un ritmo vertiginoso, generando gran impacto en la vida de los mayores. Partimos de considerar a las personas mayores como sujetos activos y en pleno ejercicio de sus derechos, donde la inclusión digital forma parte la inclusión social. Así, el objetivo de este trabajo es, por un lado, realizar un análisis de contenido de las políticas implementadas en Argentina en materia de inclusión digital, lo que incluye el nivel de cobertura y relevamiento de posibles brechas existentes. Por otro lado, se analizan datos de una encuesta nacional sobre acceso a recursos y uso de tecnologías de información y comunicación por parte de las personas mayores. Las conclusiones muestran que existen brechas importantes tanto en el acceso a recursos comoen la frecuencia de uso. Sobre las políticas públicas nacionales en la materia, observamos que la pandemia evidenció que no hubo un plan estratégico para el logro de una política de inclusión de las personas mayores a las nuevas tecnologías.
