Effect of the Different Ski Length on the Level of Anxiety at Novice Skiers
Authors: Jurečka Jan
Published: December 2020

An efficient teaching of alpine skiing at the beginning of the teaching process should be the main goal of every ski instructor. In our research we were investigating the influence of different ski length on alpine skiing teaching process efficiency as well as on the level of state anxiety during the alpine skiing at ski novices. The research was conducted on 34 participants (19 men, 15 women). Experimental group had skis of 130cm length and 7m radius from brand Lusti. Skis are specialized for very short and aggressive turning including funcarving. Mean height of participants from the experimental group was 178,07cm (±10,89). Control group had skis of standard length according to a person´s height. Meat height of participants from the control group was 177,33cm (±6,87). Mean length of skis were 158,6cm and 14,05m radius. For our research following data were collected: pre-test, continuous test and post – test of state and trait anxiety.  In this presented paper the main intention was to determine the effect of different ski length on state anxiety level at novice skiers. The data were acquired from the questionnaire STAI, which shows the level of anxiety (Künzell, S. & Müler, J., 2008; Koca, 2015). Based on the results we can say that teaching alpine skiing with usage of short skis might be less stressful for novice skiers than with usage of standard length skis.
The Effect of Age and Anthropometric and Somatic Variables on Agility Performance in Adolescent Ice Hockey Players
Authors: Ondra Lukáš , Svoboda Zdeněk
Published: December 2020

Agility, one of the components that affect performance, is beneficial in invasion sports, such as ice hockey. This study aimed to assess the relationship between agility and pubescence in adolescent male ice hockey players. Agility and anthropometric and somatic data were evaluated in 60 male participants (age, 12.98 ± 1.44 years). Participants were divided into 5 groups according to age from 11 to 15 years (11y to 15y). Anthropometric and somatic variables were observed using a bioelectrical impedance device. Agility performance level was evaluated by T-Test and Edgren Side Step Test (EDGREN). Significance level was set at p ≤ 0.05. One-way analysis of variance was used to investigate mean differences. A significant effect of age was found for height, body weight, and skeletal muscle mass percentage. Tukey’s (HSD) post hoc test revealed significant differences in height and body weight between all age groups. The T-Test revealed significant differences between all groups, except between groups 11y and 12y, 12y and 13y, and 14y and 15y. EDGREN showed differences only between groups 11y and 13y and 11y and 15y. Significant Pearson correlations were found between all monitored variables and both agility tasks. Agility improves with age in adolescent male ice hockey players. EDGREN is suitable for testing agility skills in children from the end of middle childhood to early adolescence because it is less influenced by anthropometric and somatic variables. The T-Test should be used in testing agility in late adolescent and adult athletes when maturation is completed.
Phenomenology of Emptiness
Authors: Svigaris Žilvinas ,   Polish Academy of Sciences
Published: December 2020

The living world is expanding thanks to the rapid and massive expansion of new technological capabilities. At the same time, paradoxically, it has been narrowed as thinking itself has become narrower and impoverished. Thinking has been pushed away by knowledge in almost all areas of the living world. Instead of thinking, modern man is becoming more and more curious. The acquisition of massively produced knowledge has become a form of consumption or even of entertainment. New theories that appear every day and reveal the failures of the previous ones only emphasize the limitations and fragmentation of the attitude itself. Although such knowledge is useful in solving practical local tasks, its universal validity is unfounded. What is needed is a more open consciousness which is able to reconcile different modes of experience. The rejection of ancient spiritual contemplating traditions and desacralization have impoverished the ability to express reality. This paper presents—as an attempt to recreate contemplative thinking—the conceptions of Martin Heidegger and Shinichi Hisamatsu, two thinkers living in different cultures. The paper pays a special attention to the way of being. The articulation of the state and the posture of the thinker and his/her attitudes uses concepts, that are often ambiguous, multidimensional, but already capable of articulating phenomena that could not otherwise be named. Such a stance paves the way for creative thinking capable of extending and overstepping the limits of the strict causal Western way of thinking.
The Problem with Trusting Unfamiliar Faculties
Authors: Egeland Jonathan ,   Romanian Academy - Iasi Branch
Published: December 2020

According to accessibilism, there is an accessibility condition on justification. More specifically, accessibilism claims that facts about justification are a priori accessible—where a priori is used in the traditional sense that a condition is a priori just in case it doesn’t depend on any of the sense modalities. The most prominent argument for accessibilism draws on BonJour and Lehrer's unfamiliar faculty scenarios. Recently, however, several objections have been raised against it. In this article, I defend the argument against three prominent objections from the recent literature.
Original Facticity and the Incompleteness of Knowledge
Authors: Gómez-Alonso Modesto ,   Romanian Academy - Iasi Branch
Published: December 2020

This article critically explores Nuno Venturinha’s project of capturing how we are situated in reality, a project grounded in the conviction that the closure of knowledge and the openness of experience are compatible. To this end, I will explore how an approach complementary to Venturinha’s method—one which regards the passive and the active in knowledge as rooted in a single, underlying original form of consciousness—would deal with the issue of justifying contingency without falling into either scepticism or empiricism.
On Contexts, Hinges, and Impossible Mistakes
Authors: Boncompagni Anna ,   Romanian Academy - Iasi Branch
Published: December 2020

In this commentary on Nuno Venturinha’s Description of Situations, after highlighting what in my view are the most significant and innovative features of his work, I focus on Venturinha’s infallibilist approach to knowledge. This topic allows for a wider discussion concerning the pragmatist aspects of the later Wittgenstein’s philosophy. I discuss this in three steps: first, by describing the general similarity between Wittgenstein and the pragmatists with respect to the emphasis on contexts; second, by focusing on the kind of fallibilism endorsed by the pragmatists and its compatibility with Charles S. Peirce’s concept of the “indubitables,” which I take as a precursor of Wittgenstein’s concept of hinges; and, finally, by advancing the hypothesis that it is possible to find a form of fallibilism in the later Wittgenstein too, notwithstanding his insistence on the impossibility of mistakes. My conclusion is that while Venturinha’s contextualism finds support in the later Wittgenstein’s writings, his infallibilism does not.
Social Situations and Which Descriptions
Authors: Lewiński Marcin ,   Romanian Academy - Iasi Branch
Published: December 2020

In this paper, I approach Venturinha’s ideas on contextual epistemology from the perspective of linguistic practices of argumentation. I point to the “thick” descriptions of social situations as a common context in which our epistemic language-games take place. In this way, I explore promising connections of Venturinha’s work to key concepts in recent speech act theory, social ontology and social epistemology.
SPATIAL CHARACTERIZATION OF TELECOMMUNICATION SATELLITES VISIBLE ABOVE THE REPUBLIC OF SERBIA
Authors: Đukanović Slaviša , Mladenović Vladimir , Gligorijević Milan , Milošević Danijela , Radojević Aleksić Ivona
Published: December 2020

This paper deals with the general technical, spatial, and temporal characteristics of satellite telecommunications systems. Particular attention was paid to the peculiarities of the territory of the Republic of Serbia in terms of implementation and use of modern satellite telecommunication infrastructure. The overview shows how and on which way to use various satellite telecommunication systems to configure and exploit next-generation networks, especially modern communications such as 5G technology and IoT. Their work cannot be imagined without the high speeds and high frequencies that allow us to transmit a wealth of information - from short messages/news to HD video on a mobile phone. We need either a base station network or in the case of the high seas or areas where the base station system is difficult to imagine, we need satellite communication. The paper presents data that give a numerical and graphical overview of geostationary satellites visible from the territory of the city of Belgrade, depending on the orbital position and the associated angle of azimuth and elevation, which would also be valid for the leading territory of Serbia.
La posición del verbo en la frase y el ritmo en el sistema de Alviero Niccacci
Authors: Salvador Adriana Noemí
Published: December 2020

A partir de la interpretación dada al onomástico divino veterotestamentario y la partícula waw en las formas verbales reconocemos, dentro del sistema desarrollado por Alviero Niccacci para el análisis del verbo hebreo, el criterio de la posición del verbo en la frase como responsable de la generación del ritmo en los textos bíblicos, tanto narrativos (transiciones temporales) como poéticos (merismos). Criterio que pensamos capaz de alcanzar la ondulación vibrante del origen, ritmo original (Yhwh) y originante (waw/ἰw-hwh), propio de las lenguas primitivas, abriéndose en dos direcciones: con la waw y el Tetragrama, en el contacto con el egipcio, en cuanto lengua afroasiática; y con la categoría de actualidad en el mensaje, hasta nuestra existencia (verbo ser) contemporánea. De este modo, en la posición del verbo, se reconoce una teología implícita en la sintaxis; el ritmo primitivo, original y originante.From the interpretation given to the divine veterotestamentary onomastic and the waw particle in verbal forms we recognize within the system developed by Alviero Niccacci for the analysis of the Hebrew verb, the criterion of the position of the verb in the phrase as responsible for the generation of rhythm in biblical texts, both narrative (temporal transitions) and poetic (merismus). Criterion that we think is able to achieve the vibrant ripple of the origin, original rhythm (Yhwh) and originant (waw/ἰw-hwh), typical of primitive languages opening in two directions: with waw and Tetragram in contact with the Egyptian as an Afroasiatic language, and with the category of actuality in the message until our contemporary existence (verb to be). Thus, at the position of the verb an implicit theology is recognized in the syntax, the primitive original and originant rhythm.

Processos de ensino e aprendizagem em Matemática na Educação Básica: a perspectiva das aulas como experiência formativa no estágio supervisionado
Authors: Costa André Pereira da , Oliveira Anatália Dejane Silva de
Published: December 2020

O objetivo deste artigo consiste em analisar as dinâmicas de aulas de Matemática como processos de ensino e de aprendizagem no Ensino Fundamental e no Ensino Médio, durante vivências realizadas no estágio supervisionado em duas escolas públicas de um município do Oeste da Bahia. Na abordagem teórica, tecemos considerações acerca da significação dos processos de ensino e aprendizagem na constituição de relação pedagógica como ambiente relacional de buscas, trocas e partilhas. Nessa compreensão, a aula está configurada como atividade coletiva produzida conjuntamente entre alunos e professores, em situação pedagógica compartilhada no ato de conhecer a Matemática. O percurso metodológico apresenta uma abordagem qualitativa, na qual realizamos análise documental de protocolos de observação, instrumentos de registro de dados, trabalhados a partir da análise de conteúdo. No âmbito dos resultados, destacamos que nas metodologias de ensino observadas nas aulas de Matemática nos anos finais do Ensino Fundamental, bem como no Ensino Médio, há preponderância da aula expositiva, em especial, no ensino de Álgebra e de Estatística. No entanto, ressaltamos que múltiplas estratégias mobilizaram as atividades de ensino e produziram desdobramentos que diversificaram esse tipo de aula, sobretudo, no trabalho com Números. Concluímos que o estágio supervisionado consiste em espaço significativo de formação inicial de professores e de atualização profissional para quem ensina Matemática na Educação Básica, pois permite ressignificar os processos de ensino e aprendizagem sob o ponto de vista de seus estudantes.

Authors: Corradi Raquel Polizeli , Franco Valdeni Soliani
Published: December 2020

Este artigo é parte de uma pesquisa de doutorado em Educação Matemática e se propõe a analisar a atividade de visualização, colaborando para a discussão da temática em cursos de licenciatura em Matemática, contribuindo para que mais alternativas que favoreçam a aprendizagem em Geometria sejam encontradas. Tem-se por objetivo investigar a atividade de visualização na resolução de uma tarefa de Geometria por acadêmicos de um curso de licenciatura em Matemática de uma Universidade ao norte do estado do Paraná, ao ingressarem no curso e ao concluírem as disciplinas de Geometria constantes na estrutura curricular do referido curso, e também identificar se os conceitos Geométricos requeridos na tarefa estão matematicamente consolidados. Trata-se uma pesquisa qualitativa, na perspectiva do paradigma interpretativo, segundo a modalidade estudo de casos múltiplos. A fundamentação teórica para análise dos dados se pauta nas ideias apresentadas por Duval e por Gutiérrez sobre a visualização em Geometria. Foi observado que os elementos e operações que compõe a visualização ocorrem, de modo geral, nos dois grupos. Porém, notou-se uma diferença -ainda que pequena- entre o desempenho dos integrantes dos grupos. Foram observadas dificuldades em relação ao conceito formal de quadrado e ao emprego de alguns dos elementos e operações que compõe a visualização pela perspectiva adotada.

Published: December 2020

En este volumen se entrecruzan diversos ámbitos que vienen gozando de una paulatina revisión crítica a lo largo de la última década: en primer lugar, las creaciones cinematográficas realizadas en la España de la Transición con un carácter más o menos documental; en segundo lugar, las representaciones culturales de las«minorías sexuales» durante una época tan turbulenta como aquella; en tercer lugar, la recuperación de testimonios marginados por la historiografía más vetusta.
Una aproximación al ecofeminismo en el contexto latinoamericano: desde la perspectiva literaria, social y criminológica
Authors: Romero-Pérez María Isabel , Vásquez-Hernández Yaritza María , Montenegro-Ayala Rocío Belén
Published: December 2020

Frente a una mirada globalizadora desde el contexto latinoamericano, en la cual la vulneración del medio ambiente provoca tensiones y conflictividades que van en detrimento del desarrollo sostenible, se debe estudiar la intervención de la mujer desde una mirada ecofeminista. Este enfoque invita a reivindicar la justicia ambiental desde la sororidad, como una red de apoyo entre la lucha de las mujeres para hacer frente al daño medio ambiental. Tomando como referencia la revisión documental, este artículo se basa en el análisis descriptivo e interpretativo de los principales aspectos vinculantes a la corriente del ecofeminismo, desde la perspectiva literaria, social y criminológica; en el cual se ven perjudicados una serie de derechos como son el derecho al medio ambiente sano, el territorio y los recursos naturales que yacen en los pueblos de América Latina. Además, se hace énfasis en el rol de las ecofeministas como agentes transformadoras del cambio ambiental.

Journalistisk dækning af danske shitstorme: Genmæle, vidensbidrag og kildekontakt
Authors: Olsen Emil , Andersen Nicklas , Zachrau Ida
Published: December 2020

I denne artikel undersøger vi, hvordan danske journalister dækker det relativt nye, online mediefænomen ’shitstorme’. Vi argumenterer først for, at shitstorme er et biprodukt af negativ electronic word-of-mouth på sociale medier, og at shitstorme skal forstås i sammenhæng med allerede eksisterende studier af medieskandaler. Herefter etablerer vi en analyseramme til vores indholdsanalyse ud fra en række journalistiske idealer, som vi mener, at de fleste professionelle journalister bør kunne tilslutte sig – at journalister bør lytte til og give den anklagede part mulighed for genmæle, forsøge at tilføje nye og eksklusive kilder og perspektiver til deres historier og verificere og faktatjekke informationer. Vores empiri er indsamlet via Infomedia og består af i alt 1.107 artikler, der omhandler 10 shitstorme fra 2019. Vi kan ud fra vores analyse konkludere, at de fleste journalister lader den anklagede part komme til genmæle, og at journalisterne også forsøger at tilføje eksklusive og nye kilder og perspektiver til deres historier. Ydermere kan vi konkludere, at shitstorme, hvor kritikken er rettet mod politiske aktører, i højere grad motiverer kildekontakt. Med afsæt i de analytiske konklusioner diskuterer vi afslutningsvis idealernes relevans i dækningen af shitstorme.
Sports Journalism, Interns and #MeToo – did anything change?
Authors: Orgeret Kristin Skare , Røsok-Dahl Heidi
Published: December 2020

Norwegian news media were central actors in the dissemination of information about the #MeToo movement. Simultaneously, the media are made up of institutions and workplaces that are at times characterized by asymmetrical power relations. The aim of this article is to understand how those considered at the bottom of such power relations: young (female) interns in the sports journalism departments, experienced the effects of the #MeToo movement. Addressing the question if #MeToo changed anything, this article emphasizes the importance of combining the position that sexual harassment is not necessarily associated with a specific gender, at the same time recognizing that such harassment has first and foremost been part of a structural suppression of women. The article illustrates how facets of the journalistic culture and the myth of the “male genius” have marginalized those with unequal access to power in sports journalism, but also that the #MeToo movement has the potential to change this.
Dyrenes betydning i religion og filosofi – en oversigt
Authors: Albinus Lars
Published: December 2020

Lars Albinus

ENGLISH ABSTRACT: In this article, I present an overview of the meaning and significance of animals in a religious context, ranging from tribal cultures to a Christian tradition. Furthermore, I will draw a line to current philosophical and eco-critical debates. My thesis is that in many cultures humans have had a tendency to regard animals as a mediating link between life in this world and a transcendent form of being. In animistic and totemistic ontologies animals are closely related to divinities as well as to humanity as such, whereas in more developed forms of religion they become part of a hierarchy as mediators between humans and gods. This is seen, for instance, in sacrificial cult. Later their significance decreases according to their predominant role of being moral similes. In our own times, however, animals seem to regain a significance as beings in their own right owing to our increasing ecological awareness. Prominent philosophers such as Derrida and Agamben have thus questioned the traditional view of human exceptionalism and opened up for a new understanding of the relationship between being animal and being human. I finally suggest that Agamben’s concept of ‘bare life’ and an eco-critical notion of stewardship concerning endangered species, as well as animals in general, both conceive of the animal as a new kind of immanent transcendence.

DANSK SUMMARY: Jeg tegner i denne artikel et omrids af dyrenes betydning i en religiøs kontekst (fra stammefolk til en kristen tradition) samt i en filosofisk og øko-kritisk optik. Min tese er, at dyrene i mange kulturer har ansporet mennesket til at se dem som bindeled mellem livet i denne verden og en transcendent væren. I animistiske og totemistiske ontologier er dyrene tæt forbundet med både mennesker og guder, hvorimod de i de arkaiske religioner indgår i et hierarki, hvor de, blandt andet gennem ofringer, udgør den medierende instans mellem mennesker og guder. Senere antager de hovedsagelig en metaforisk betydning som moralske sindbilleder. Vores egen tid oplever en stigende økologisk bevidsthed om dyrenes egenværdi, og markante filosoffer som Derrida og Agamben har stillet spørgsmål ved den traditionelle grænse mellem dyr og mennesker, som antropocentrismen har levet højt på i århundreder. Jeg hævder i den forbindelse, at der hersker en indbyrdes forbindelse mellem Agambens begreb om det nøgne liv og en øko-kritisk omsorg for dyret, som gør det til en ny form for immanent transcendens.
DECOLONIZING THE REPRESENTATIONS ABOUT COLONIZATION: GEOGRAPHIC REFLECTIONS
Authors: Bernardo Neto Jaime
Published: December 2020

Most representations about the process of spatial expansion of capitalism over the spatial cuts that today constitute what we know as Brazil and Latin America, through the advance of colonization, perpetuates what some authors have been calling ideology of demographic voids, which would be the tendency to represent these spaces before their appropriation and incorporation into the capitalist world system as desert areas, without human beings, thus concealing the violence inherent in it. Despite the advances in Contemporary Social Theory, this type of timespace representation has still been reproduced and perpetuated in many historiographic and academic works from different areas of knowledge. The following article presents reflections on this phenomenon, developed with fulcrum in studies on the spatial profile that today constitutes the State of Espírito Santo, in order to understand the theoretical vices that corroborate the perpetuation of this type of representation.
Socio -Territorial Transformations of the Northeast Region of Uruguay (2000-2018)
Authors: Pereira Rodrigo , Borras Marcel , Scaraffuni Gabril , Cancelier Janete
Published: December 2020

This article aims to understand how socio-territorial transformations have been manifesting in the northeast region of Uruguay between 2000 and 2018. In this period, the territorial expansion of agribusiness through soy monoculture and forestry intensifies, which causes important changes in the productive, social, and landscape base. The objective is, on one hand, to describe quantitatively and in terms of changes in land use, the recent transformations in the agrarian territories of the region and, on the other hand, to understand the impacts of these processes on some social dynamics, especially in the migration of family producers and their families from the agrarian space to the urban one. The methodology included a bibliographic and documentary review, the analysis of statistical data from the General Agricultural Census, and the analysis of land use through satellite images. The results show that monocultures linked to agribusiness have modified the agrarian structure and the use of the territory resulting in increasing pressure on the price of land, which puts the permanence of family producers at risk
THE PANDEMIC AND THE ‘ENVIRONMENTALISATION’ OF GEOGRAPHY. AN EPISTEMIC-POLITICAL CHALLENGE
Authors: Souza Marcelo
Published: December 2020

The purpose of this article is to extract from the COVID-19 pandemic a lesson for geographers: although without intending (or being possible) to simply go back to the past, it is necessary to re-value, nevertheless, the very quintessence of the identity of the geographical discourse, which has been characterised by a way of building epistemic objects that is committed to a dialogue between social research (represented by what we usually call‘human geography’) and natural research (represented by what we usually call ‘physical geography’). This project, presently called ‘environmentalisation,’ does not aim at anything overly ambitious: there is no case here for an exclusionary thesis in the style ‘geography should be this, and nothing else’; in fact, it just defends the idea that an approach such as that of environmental geography, resulting from an attempt at ‘environmentalisation,’ must have its place assured. Environmental geography, being committed to the construction of hybrid epistemic objects, allows us to mobilise the interfaces and knowledge necessary to deal with complex tasks such as the analysis of the short and long-term effects of the pandemic (among many other issues). However, the environmental geography project not only has to deal with intellectual challenges (integrating what knowledge, how and for what purpose?), but, in the end, it must also face political obstacles: the concrete power relations in the academic world and the zeal with which ‘borders’ and ‘territories’ are patrolled and defended, not to mention the resistance of many researchers to leave their thematic and theoretical-methodological comfort zones.
GEOREPRESENTATIONAL PERSPECTIVES IN THE OPERATIONALIZATION OF A TERRITORIAL HERITAGE’S ATLAS. EXPERIMENTATION IN JOÃO NEIVA - ES
Authors: Nossa Damiany , De Almeida Renata
Published: December 2020

Heritage, as a concept and disciplinary field, undergoes conceptual expansions, aimed to overcome the conservation-development dichotomy, in two perspectives: spatial, by embracing scales beyond the object’s scale; and temporal, for inserting the procedural perspective of the territory as a social construction. Heritage enlarged to a territorial scale requires research methods that go through architecture and approach the field of Geography. As a potential method, the Territorialist Information Systems are presented, reviewing base data from the Atlas of Territorial Heritage, in order to compose a diachronic-evolutionary framework, showing processes of dissipation and maintenance of heritage in João Neiva – Espírito Santo.

Capital fluidity, Amazonian cities collapsing notes on the energy and humanitarian crisis in the state of Amapá
Authors: Frabetti Giancarlo
Published: December 2020

This text aims to discuss the foundations of the energy and humanitarian crisis that, in early November 2020, affected the state of Amapá. In order to achieve this goal, we firstly present how the process of Amapá's integration with the National Interconnected System (SIN) took place, and then point out the technical weaknesses that incurred in the interruption of the energy supply in the state. In parallel, we discuss the business structure and financial logic involved in the poor provision of the service offered by the company responsible for the Macapá substation. Finally, we introduce some information about the political causes and consequences of the blackout, raising questions about the privatization process of urban infrastructures whose functioning is essential to life in Amazonian cities.

ELECTRIFICATION, URBAN LIFE AND THE ROLE OF WOMEN
Authors: Seabra Odette
Published: December 2020

Technological innovations have significantly changed the society in many ways. This paper analyses the major changes caused by the development and the spread of electric energy utilization in the production of urban space, in labour, in the organization of family and households, in everyday life and in the role of women, such as the changes brought to the households as an outcome of the introduction of everyday technologies in them, as well as in the role they play, whether in the job market, in the artistic and political vanguards and in the fight for rights, as well as in their role of household management as the person responsible for maintaining the conditions of social reproduction of their families. This debate is supported by the notions of modern, modernization, modernity and utopia, while highlights the contradictions and inequalities that remain and permeate the life of the working class in the cities.
Hypertricosis overlying plexiform neurofibroma in a female patient: a rare presentation
Authors: Shah Faizan Younus , Keen Mohammad Abid , Kitab Ifrah Shafat , Shah Aaqib Aslam
Published: December 2020

Periorbital neurofibromas can occur either in isolation or in association with neurofibromatosis (NF). Neurofibromas in the periorbital region account for 0.5-2.4% of orbital tumours. Hypertrichosis overlying neurofibromas are rarely reported cases in literature. We report a case of localized hypertrichosis overlying neurofibroma in a 27 year old female with no other features of neurofibromatosis. Neurofibromas can occur as solitary lesions or in association with neurofibromatosis. Our patient had diffuse hypertrichosis on a hyperpigmented macule overlying and around the periorbital neurofibroma.

Hypothetical proteins (HPs) are those whose sequence is present but nothing is known about their structural and functional annotations. Elucidation of structural and functional insights would be effective enough in perceiving the protein interactions and their involvement in various pathways and networks. Ananas comosus is considered as third most essential tropical fruit and is given more consideration from the commercial point of view; therefore, in this research, it is taken for analysis using different approaches of bioinformatics. On the basis of subcellular localization and secondary structure analysis, it was suggested that HP is the nuclear protein consisting of α helices and more abundant coils. Homology modeling has been done through Swiss Model to determine their template structure but template identity score is not enough which uncover the fact that the protein OAY63476.1 is unpredicted in-vitro. In order to predict the 3D structure of protein, Phyre 2 server is utilized. Results are validated by different strategies revealing the stability of the developed model. The quality factor of this protein is 45.28. Functional analysis and domain identification have been performed by using NCBI-CDD and Pfam which suggested that protein contains ring variant domain. Comparative genome analysis has been performed with other proteins of plants which demonstrate that the selected protein has the highest similarity. This study paves the way in order to determine the structural and functional annotations of other uncharacterized proteins and effective in exploring other novel proteins along with their functions in the same way as that of this research study.
Power-line Interference Removal from High Sampled ECG Signals Using Modified Version of the Subtraction Procedure

The acquired ECG signals are often contaminated by residual Power-line Interference (PLI). A lot of methods, algorithms and techniques for PLI reduction have been published over the last few decades. The so called subtraction procedure is known to eliminate almost totally the interference without affecting the signal spectrum. The goal of our research was to develop a heuristic version of the procedure intended for ECG signals with high Sampling Rate (SR) up to 128 kHz. The PLI is extracted from the corrupted signal by technique similar to second order band-pass filter but with practically zero phase error. The sample number as well as the left and right parts outside the samples belonging to a current sine wave, which is extracted from the contaminated signal, are counted and measured. They are used to compensate the error arising with the shift between the moving averaged free of PLI signal samples and their real position along the linear segments (usually PQ and TP intervals having frequency band near to zero). The here calculated PLI components are appropriately interpolated to ‘clean’ the dynamically changed in amplitude and position contaminated samples within the non-linear segments (QRS complexes and high T waves). The reported version of the subtraction procedure is tested with 5 and 128 kHz sampled ECG signals. The maximum absolute error is about 20 μV except for the ends of the recordings. Finally, an approach to PLI elimination from paced ECG signals is proposed. It includes pace pulse extraction, signal re-sampling down to 4 kHz and subtraction procedure implementation followed by adding back the removed pace pulses.
Clinical Effects of Vitamin D on the Control of Bronchial Asthma-Is it Relevant?
Authors: Gaude Gajanan S , Kummarganti Sreenija , Hattiholi Jyothi
Published: December 2020

Bronchial asthma is one of the most common chronic respiratory disease worldwide, and is characterised by different phenotypic variations. Acute exacerbations in bronchial asthma are common and leads to repeated hospitalisations leading to increase in direct costs of asthma and thus preventing exacerbations should be an important consideration. Vitamin D has an immunomodulatory action and its deficiency has been associated with asthma epidemics. We hereby critically review the clinical benefits of vitamin D in the control of bronchial asthma and in exacerbations.

On investigation, he was found to be having hypokalemia as well as thyrotoxicosis. His potassium was corrected and was put on non-selective beta blocker and carbimazole. The patient improved within 24 hours and was discharged with advice to continue with Inderal and Carbimazole and report after one month. Hyperthyroidism should be included in differential diagnosis of sudden onset lower limb weakness.

Cortical deafness is a clinical rarity whereby a patient is unresponsive to all types of sounds despite the preserved integrity of the peripheral hearing organs. In this study, we present a patient who suddenly lost his hearing following ischaemic infarcts in both temporal lobes with no other neurological deficits. The CT confirmed damage to the primary auditory cortex (Heschl’s gyrus) of both hemispheres. Initially, the patient was unresponsive to all sounds, however, he regained some of the auditory abilities during 10 months follow up. Pure tone threshold improvement from complete deafness to the level of moderate hearing loss in the right ear and severe in the left was observed in pure tone audiometry. Otoacoustic emissions, auditory brainstem responses, and acoustic reflex findings showed normal results. The middle and late latency potential results confirmed objectively the improvement of the patient’s hearing, however, after 10 months still, they were somewhat compromised on both sides. In speech audiometry, there was no comprehension of spoken words neither at 3 nor at 10 months. The absent mismatch negativity confirmed above mentioned comprehension deficit. The extensive auditory electrophysiological testing presented in this study contributes to the understanding of the neural and functional changes in cortical deafness. It presents the evolution of changes after ischaemic cerebrovascular event expressed as auditory evoked potentials starting from short through middle and long latency and ending with event-related potentials and supported by neuroimaging.

New radionuclide‐labeled targeting nanocarrier systems have generated new opportunities for tumor treatment and imaging. Nevertheless, such therapeutic strategy is clinically unfeasible on anaplastic thyroid carcinoma (ATC) patients, because of lacking suitable targets and resistance to radiation. In order to figure out a potential treatment, immuno‐histochemical staining is performed in human ATC tissue species and high expression of cluster determinant 44 (CD44) is found. Therefore, a CD44‐targeted delivery system is designed and constructed by self‐assembly of tyrosine (Tyr)–hyaluronic acid (HA)–polyethyleneimine (PEI), which can radiolabel 131/125I and load a p53 mutant restoring regent, Prima‐1. The 125I‐labeled nanocomposites display an impressive tumor imaging as well as a long radiation treatment cycle. The 131I‐labeled nanoparticles show remarkable anti ATC‐tumor effects in vitro and in vivo, due to radiosensitization of Prima‐1 by reactivation of the p53 mutants.

The silane treatment on properties of fly ash (FA) and development of its composite using recycled poly(vinyl chloride) (r‐PVC) material retrieve from waste wires and cable insulation are investigated in this work. The use of (3‐aminopropyl)triethoxysilane was employed as a coupling agent with some other essential additives. The composites sheet was prepared by means of the melt mixing process and go along with the compression molding process. The superior properties on compatibility between silane‐modified FA (FA(Si)) and r‐PVC were successfully studied using rheological, thermomechanical, morphological, and water absorption analysis. Primary analysis of r‐PVC and FA was employed using Fourier transform infrared spectroscopy analysis. The thermal stability of composites was stable up to 187°C. In addition, significant enhancement on tensile strength as well as young's modulus of composite as compared to untreated r‐PVC/FA composites. Morphological properties of silane treated FA based composites presented the good distribution and excellent uniformity with higher wettability of FA particles within r‐PVC matrix. The water absorption test showed decrease in water absorption with increase silane treatment concentration FA in the r‐PVC matrix. It was remarkable to note that silane treated FA can be prepared as a composite using r‐PVC matrix with further modified properties.
Medication and healthcare utilization variation among older adults with pain

Published: December 2020

Background

While pain is very common in older adults, the associated impact on daily life, including usage of medication and healthcare, varies considerably and often pain remains inadequately treated. It is not clear what is associated with this variation.

Methods

Latent class analysis (LCA) is a model‐based approach to identifying underlying subgroups in a population. In this study LCA was used to examine biopsychosocial risk classes of adults aged 50 years and older, who were often troubled by pain, from The Irish Longitudinal Study on Ageing (TILDA), (n = 2,896), and the associations with future medication and healthcare use.

Results

Four biopsychosocial risk classes (Low Biopsychosocial Risk, Physical Health Risk, Mental Health Risk, High Biopsychosocial Risk) were identified, with the 'High Biopsychosocial Risk' class accounting for 24% of older adults with pain. This class were much more likely to use medication and healthcare services when followed up across three waves of the TILDA study. In contrast, the Physical Health Risk and the Mental Health Risk classes reported lower usage of medication and healthcare at waves 2 and 3. Amongst the higher risk classes of older adults who are troubled by pain, there is considerable consumption of medication and healthcare services evident.

Conclusion

Given our ageing population and significant number of adults in this high risk class, there is a need to optimize current pain management approaches among older adults. Intensive non‐pharmacological approaches to pain management in older adults, tailored to individual biopsychosocial risk indicators for each individual class, may be worth exploring.

Significance

While pain is very common in older adults, the usage of medication and healthcare varies considerably and often pain remains inadequately treated. Given our ageing population and the significant number of older adults reporting high biopsychosocial risk (24%), there is a need to optimize current pain management approaches. Intensive non‐pharmacological approaches to pain management in older adults, tailored to individual biopsychosocial risk indicators for each individual class, may be worth exploring.
Berry Curvature and Riemann Curvature in Kinematic Space with Spherical Entangling Surface
Authors: Huang Xing , Ma Chen‐Te
Published: December 2020

We discover the connection between the Berry curvature and the Riemann curvature tensor in any kinematic space of minimal surfaces anchored on spherical entangling surfaces. This new holographic principle establishes the Riemann geometry in kinematic space of arbitrary dimensions from the holonomy of modular Hamiltonian, which in the higher dimensions is specified by a pair of time‐like separated points as in CFT1 and CFT2. The Berry curvature that we constructed also shares the same property of the Riemann curvature for all geometry: internal symmetry; skew symmetry; first Bianchi identity. We derive the algebra of the modular Hamiltonian and its deformation, the latter of which can provide the maximal modular chaos to the modular scrambling modes. The algebra also dictates the parallel transport, which leads to the Berry curvature exactly matching to the Riemann curvature tensor. Finally, we compare CFT1 to higher dimensional CFTs and show the difference from the OPE block.

Introduction

The population of American Indians and Alaska Natives (AI/ANs) aged 65 and older is growing rapidly, raising concerns about Alzheimer's disease (AD) in their communities.

Methods

We distributed a survey incorporating the Alzheimer's Disease Knowledge Scale to 341 AI/AN community members attending cultural events. We computed average adjusted predictions and 95% confidence intervals from a linear regression model, used joint F tests to examine differences in scores according to demographic variables, calculated the percentage of correct items for each participant, and computed domain‐specific averages across the sample.

Results

The average score was 19.0 (maximum 30); the average percentage of correct responses was 63%. Higher scores were associated with education but not with age, sex, or rural versus urban residence. Low scores were observed for items on caregiving and disease risk.

Discussion

Participants were moderately well informed about AD, but specific knowledge domains call for community outreach and education.
