Sensory neuron cultures derived from adult db/db mice as a simplified model to study type-2 diabetes-associated axonal regeneration defects
Authors: De Gregorio Cristian , Ezquer Fernando
Published: December 2020

Diabetic neuropathy (DN) is an early common complication of diabetes mellitus (DM), leading to chronic pain, sensory loss and muscle atrophy. Owing to its multifactorial etiology, neuron in vitro cultures have been proposed as simplified systems for DN studies. However, the most used models currently available do not recreate the chronic and systemic damage suffered by peripheral neurons of type-2 DM (T2DM) individuals. Here, we cultured neurons derived from dorsal root ganglia from 6-month-old diabetic db/db-mice, and evaluated their morphology by the Sholl method as an easy-to-analyze readout of neuronal function. We showed that neurons obtained from diabetic mice exhibited neuritic regeneration defects in basal culture conditions, compared to neurons from non-diabetic mice. Next, we evaluated the morphological response to common neuritogenic factors, including nerve growth factor NGF and Laminin-1 (also called Laminin-111). Neurons derived from diabetic mice exhibited reduced regenerative responses to these factors compared to neurons from non-diabetic mice. Finally, we analyzed the neuronal response to a putative DN therapy based on the secretome of mesenchymal stem cells (MSC). Neurons from diabetic mice treated with the MSC secretome displayed a significant improvement in neuritic regeneration, but still reduced when compared to neurons derived from non-diabetic mice. This in vitro model recapitulates many alterations observed in sensory neurons of T2DM individuals, suggesting the possibility of studying neuronal functions without the need of adding additional toxic factors to culture plates. This model may be useful for evaluating intrinsic neuronal responses in a cell-autonomous manner, and as a throughput screening for the pre-evaluation of new therapies for DN.

It is essential that patients are worked up appropriately and referred promptly to a specialist unit for consideration of replantation. This review summarises the acute management of a patient presenting to the emergency department with an amputated digit. It discusses the assessment, initial management in the emergency department, how to make the decision to replant and operative steps.
The influence of Catholicism on social work: from classic conservatism to critical renewal
Authors: Quintero Sergio
Published: December 2020

This article takes a journey through history to demonstrate the defining role of social and political conditions on the professionalisation of social work in Latin America. An analysis is made of the influence of the Catholic Church, showing the transition from classic conservative thought towards conservative modernisation and up to aggiornamento and Liberation Theology. Some specific features of the case of Colombia are presented, highlighting the experience of Camilo Torres and Golconda. Through documentary qualitative analysis the influence of the critical renewal of the Catholic Church on Reconceptualisation can be seen, clearly demonstrating the incorporation of a certain degree of Marxism that excludes a critique of political economy.

Published: December 2020

Sub-aperture tool polishing of precision optics requires a detailed understanding of the local material removal [tool influence function (TIF)] at the contact spot between the workpiece and tool to achieve high removal determinism and hence precision of the optic relative to the desired/design surface figure. In this study, the mechanisms influencing and the quantitative prediction of the removal rate and shape of TIF spots during polishing of fused silica glass with cerium oxide slurry using a rotating hemispherical pad-foam tool for a wide variety of process conditions (including tool properties, kinematics, and applied displacements) are investigated. The TIF volumetric removal rate can be estimated utilizing the average relative velocity and contact area using a simple analytical model. In addition, stability of the volumetric removal rate for fixed process conditions is shown to be greatly dependent on the pad preparation and amount of tool use (affecting both pad topography and slurry buildup), whose general behavior shows an increase in removal rate followed by stabilization with polishing time. The determination of the TIF removal shape is more complex. An extended version of the Preston removal model is developed to explain a comprehensive set of measured TIF removal shapes to within

. This model incorporates a number of phenomena impacting the TIF removal shape including: (a) temporal and spatial dependent relative velocity between the workpiece and tool; (b) an elastic mechanics based, as well as hydrodynamic, pressure distribution; (c) a spatially dependent friction coefficient possibly caused by both reduced slurry replenishment in low velocity regions and pad slurry islands (100 µm scale) and porosity (millimeter scale); and (d) a shear-based removal mechanism on the periphery of the contact spot.
Relationship between cardiac biomarker concentrations and long-term mortality in subjects with osteoarthritis
Authors: Rehm Martin , Büchele Gisela , Peter Raphael Simon , Brenner Rolf Erwin , Günther Klaus-Peter , Brenner Hermann , Koenig Wolfgang , Rothenbacher Dietrich
Published: December 2020

Osteoarthritis (OA) is associated with adverse cardio-metabolic features. N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity troponins T and I (hs-cTnT and hs-cTnI) are well-characterized cardiac markers and provide prognostic information. The objective was to assess the association of cardiac biomarker concentrations with long-term mortality in subjects with OA. In a cohort of 679 OA subjects, undergoing hip or knee replacement during 1995/1996, cardiac biomarkers were measured and subjects were followed over 20 years. During a median follow-up of 18.4 years, 332 (48.9%) subjects died. Median of hs-cTnT, hs-cTnI, and NT-proBNP at baseline was 3.2 ng/L, 3.9 ng/L, and 96.8 ng/L. The top quartile of NT-proBNP was associated with increased risk of mortality (Hazard Ratio (HR) 1.79, 95% confidence interval (CI) 1.17–2.73) after adjustment for covariates including troponins (hs-cTnT HR 1.30 (95% CI 0.90–1.89), hs-cTnI HR 1.32 (95% CI 0.87–2.00) for top category). When biomarker associations were evaluated as continuous variables, only NT-proBNP (HR per log-unit increment 1.34, 95% CI 1.16–1.54) and hs-cTnI (HR 1.38, 95% CI 1.11–1.72) showed robust results. Elevated cardiac biomarker concentrations predicted an increased risk of long-term mortality and strongest for NT-proBNP and hs-cTnI. These results might help to identify subjects at risk and target preventive efforts early.

Published: December 2020

We evaluate the ocular effects of proton beam therapy (PBT) in a single institution, in Korea, and identify factors contributing to decreasing visual acuity (VA) after PBT. A total of 40 patients who received PBT for choroidal melanoma (2009‒2016) were reviewed. Dose fractionation was 60‒70 cobalt gray equivalents (CGEs) over five fractions. Complete ophthalmic examinations including funduscopy and ultrasonography were performed at baseline and at 3, 6, and 12 months after PBT, then annually thereafter. Only patients with at least 12 months follow-up were included. During the follow-up, consecutive best-corrected visual acuity (BCVA) changes were determined, and univariate and multivariate logistic regression analyses were performed to identify predictors for VA loss. The median follow-up duration was 32 months (range: 12‒82 months). The final BCVA of nine patients was > 20/40. The main cause of vision loss was intraocular bleeding, such as neovascular glaucoma or retinal hemorrhage. Vision loss was correlated with the tumor size, tumor distance to the optic disc or fovea, maculae receiving 30 CGEs, optic discs receiving 30 CGEs, and retinas receiving 30 CGEs. Approximately one-third of PBT-treated choroidal melanoma patients with good pretreatment BCVA maintained their VA. The patients who finally lost vision (VA < count fingers) usually experienced rapid declines in VA from 6‒12 months after PBT. Tumor size, tumor distance to the optic disc or fovea, volume of the macula, and optic discs or retinas receiving 30 CGEs affected the final VA.
Prediction of itraconazole minimum inhibitory concentration for Fonsecaea pedrosoi using Fourier Transform Infrared Spectroscopy (FTIR) and chemometrics
Authors: Koehler Alessandra , Corbellini Valeriano Antonio , Heidrich Daiane , Scroferneker Maria Lúcia
Published: December 2020

Fonsecaea pedrosoi is one of the main agents of chromoblastomycosis, a chronic subcutaneous mycosis. Itraconazole (ITC) is the most used antifungal in its treatment, however, in vitro antifungal susceptibility tests are important to define the best therapy. These tests are standardized by the Clinical and Laboratory Standards Institute (CLSI), but these protocols have limitations such as the high complexity, cost and time to conduct. An alternative to in vitro susceptibility test, which overcomes these limitations, is FTIR. This study determined the minimum inhibitory concentration (MIC) of itraconazole for F. pedrosoi, using FTIR and chemometrics. The susceptibility to ITC of 36 strains of F. pedrosoi was determined according to CLSI and with the addition of tricyclazole (TCZ), to inhibit 1,8-dihydroxynaphthalene (DHN)-melanin biosynthesis. Strains were grown in Sabouraud agar and prepared for Attenuated Total Reflection (ATR)/FTIR. Partial least squares (PLS) regression was performed using leave-one-out cross-validation (by steps of quintuplicates), then tested on an external validation set. A coefficient of determination (R²) higher than 0.99 was obtained for both the MIC-ITC and MIC-ITC+TCZ ATR/PLS models, confirming a high correlation of the reference values with the ones predicted using the FTIR spectra. This is the first study to propose the use of FTIR and chemometric analyses according to the M38-A2 CLSI protocol to predict ITC MICs of F. pedrosoi. Considering the limitations of the conventional methods to test in vitro susceptibility, this is a promising methodology to be used for other microorganisms and drugs.
Scenarios from the margin: Narratives of adolescents and adults about their theatre experience in contexts of social exclusion in Santiago, Chile
Authors: Retuerto Iria , Glass Penelope , Guzmán Estefanía , Dumas Teresita , Formantel Andrea , Pozo Fernanda
Published: December 2020

This article problematizes the notion of ‘transformation’ in socially engaged theatre practice. A more nuanced understanding of the impact of theatre practice in marginal contexts is constructed from narrative analysis of the theatre workshop experiences of adolescents in a rights reparation program and men serving long prison sentences. In these contexts of double exclusion (poverty combined with the condition of being prisoners and homeless or violated adolescents), the participants’ long-term remembrances make constant reference to the theatre experience having signified a transit from one space or place to another. The theatre space was identified as a place of discovery, a place of validation and a place of relocation. Their theatre experience drew meaning from its implicit contrast to their everyday reality. It was a place they decided to make their own, because within it they truly experienced feelings of wellbeing not present in the marginal spaces they were inhabiting.
Becoming a FaciliActor: Playing at fiction on the borderlines of culture
Authors: Rajendran Charlene
Published: December 2020

This article interrogates the idea of the drama educator as a FaciliActor within the sociocultural and political context of Singapore, drawing on Jacques Ranciere’s (2015) notions of fiction and dissensus to examine how the FaciliActor can expand the potential of play-based embodied learning. The term FaciliActor, coined to combine facilitator and actor capacities, and thereby emphasize the acting skills involved in facilitating a dynamic drama process, points to imaginative options that drama educators negotiate when planning and executing their roles. In particular, it highlights an educator’s ability to play with experimental options and trust the ingenuity of imagination that prods a review of what is. This includes having theatrical presence, which commands attention and invites response. Given the escalating tensions of cultural difference in plural societies, the growing need for dialogic pedagogies that develop twenty-first century competencies such as critical thinking, empathy and self-awareness points to the FaciliActor as well placed to do this through play-based and creative frameworks that allow multiple perspectives. I consider how the FaciliActor can expand dialogic options for participants when creating and facilitating a drama process, and suggest that it is useful to engage with an ‘actor’s dramaturgy’ (Barba 2010) to gain critical skills when performing.

Published: December 2020

As prevalências de excesso de peso são cada vez maiores na população infantil. A obesidade precoce em crianças pode induzir a alterações do metabolismo paralelamente a elevação do sistema oxidativo e inflamatório conduzindo a complicações cardiometabólicas a curto e em longo prazo. A detecção precoce de alterações da composição corporal em crianças pode auxiliar na modificação do estilo de vida e evitar o desenvolvimento e progressão de comorbidades associadas. Comparar as prevalências de excesso de peso e de adiposidade excessiva em crianças brasileiras matriculadas em escolas municipais centrais e periféricas. Trata-se de um estudo transversal realizado com 938 crianças de 7 a 10 anos no município de Viçosa, Minas Gerais, Brasil. Para avaliação antropométrica, foram aferidos peso, estatura e as dobras cutâneas tricipital e subescapular. O Índice de Massa Corporal (IMC) foi classificado de acordo com as recomendações da WHO (2007). A gordura corporal foi estimada pela fórmula proposta por Slaughter et al (1988) e classificada segundo McCarthy (2006). A análise estatística foi realizada no software SPSS versão 20.0, sendo considerado o nível de significância estatística de 5%. Foi realizado o teste de Mann Whitney para comparar as medianas do IMC e da gordura corporal segundo a localização das escolas municipais (centrais ou periféricas). Este estudo foi aprovado pelo Comitê de Ética em Pesquisa com Seres Humanos da Universidade Federal de Viçosa. Foram encontradas altas prevalências de excesso de peso 243 (25,9%) e de gordura corporal excessiva 284 (30,3%). Crianças de escolas periféricas apresentam maior mediana de gordura corporal (p<0,05). Não foram encontradas diferenças estatísticas para as prevalências de excesso de peso entre crianças de escolas centrais e periféricas. As crianças matriculadas em escolas periféricas apresentam maior risco nutricional em relação ao percentual de gordura corporal quando comparadas àquelas de escolas centrais. Hipóteses sugeridas para estes achados é que as famílias de crianças residentes em bairros periféricos tendem a ter um menor poder aquisitivo, limitando, portanto, a participação das crianças em aulas de esportes, além da falta de espaços públicos adequados para essa prática nas localizações em que residem. A realização de ações em saúde voltadas para a prática da alimentação adequada e incentivo a atividade física devem ser adotadas na infância como forma de reduzir o impacto causado pelas doenças crônicas na população infantil.

URBAN MOVEMENTS IN THE PROCESS OF THE LEGITIMATION OF LIBERAL DEMOCRACY: ANALYSIS OF THE ACTIVITIES OF ALTERNATIVE GROUPS AND CIVIL ORGANISATIONS AT A TIME OF EUROPEAN CRISIS
Authors: LEWENSTEIN BARBARA
Published: December 2020

This paper constitutes an analysis of urban movements, marked in the research as alternative groups and civil organisations, in terms of the new politics characteristic of new social movements. In particular it indicates that these movements, ostensibly urban, actually express demands towards the broader social system, delegitimating it in a twofold manner.  Firstly, the acceptance of certain general principles in democratic values and rules is coupled with criticism of how the system functions in practice and of the political elites in Poland, via protest, lobbying, and watchdog activities. A separate type of delegitimation embraces organisations among which we may list cooperatives and squats, as well as organisations managing concrete spaces and withdrawing from participation in public life, shutting themselves away within autonomous spaces and realising a different cultural and democratic model. In both of these groups we are thus dealing with a strongly accentuated anti-systemic and anti-capitalist attitude towards the political reality of the period of transformation in Poland. The research delivered confirmation of the overall research hypothesis adopted in the Lifewhat project, according to which in response to economic crisis civil society responds with the emergence of alternative forms of resilience, not only alleviating the consequences of the crisis but which also, as time passes and the scale of their activities increases, may give rise to a new quality – including in a political sense. The research constitutes a part of the international Lifewhat project. It was conducted on a sample of eighteen purposefully selected civil groups and organisations operating in large cities in Poland, using the method of in-depth interviews.

Published: December 2020

This article presents a detailed history of the development of a particular immersion program to teach English to young Polish students. The program draws support from two organizations, the Kościuszko Foundation and the Polish Scouting Organization. Kościuszko Foundation is dedicated to strengthening the ties between the United States and Poland as well as to increase knowledge of Poland’s history and culture in the United States. The cooperation of these two organizations developed an experience of immersion in language and cultural exchange. Both the teachers and the students in this program benefited from the opportunity to engage in a number of different types of language activities and cultural events through a summer camp experience. This program is, of course, unique, but the elements of context, culture and immersion could be used in other programs to develop English skills and knowledge in the context American culture.
Development of Intelligent Smart Metering System through Remote Monitoring and Control under Robust Conditions
Authors: Priyadharshini S. G. , Subramani C. , Preetha Roselyn J.
Published: December 2020

This paper discusses the development of intelligent smart metering infrastructure for smart buildings based on information and communication technologies. The system collects electrical parameters, like real power, reactive power, voltage, current, power factor, and energy consumption, and physical parameters, such as temperature, humidity, and occupancy of the building. The electrical data are collected using Raspberry Pi 3B along with Smart Pi module. The physical parameters are collected by using a wide range of sensors communicating with the data acquisition module wirelessly by Wi-Fi technology. The monitoring platform is developed both in the customer end for the energy user and remote end for monitoring and control by the system operator. The developed system also has a parallel mode of communication based on LoRa technology, which will come into the picture if the primary mode of communication fails, ensuring there is always a continuous transfer of data under natural disaster situations. In addition, the system has an occupancy detection–based Internet of Things control module through which the system operator can remotely control selected appliances in the customer side based on the occupancy of the building as well as during disaster situations. The developed system also paves the way for secured smart buildings by continuous tracking of the building physical parameters, like temperature, humidity, and occupancy of the building during emergency situations like floods, earthquakes, and terrorist attacks, by which relief operations can be provided.

Published: December 2020

Many studies have explained temporomandibular joint (TMJ) sounds in children are frequent with TMJ disorder. In addition to multiple divergent findings are designed to evaluate the relationship between bruxism and TMJ disorder in children. Aim: study was designed and conducted to assess the possible relationship between bruxism and joint sounds in schoolchildren. Subjects and Methods: The sample comprised 60 schoolchildren participants between 6 to 10 years of age, of whom 30 children with bruxism as study group G1 and another 30 without bruxism as a control group G2 who were scheduled and randomly selected for treatment at (Outpatient Dental Clinics, Zagazig University Hospital). Examiner performed assessment who was blinded allocation of the groups. Assessment involved of (manual palpation, lateral and dorsal extra-auricular auscultation of TMJ by stethoscope for detecting of joint sounds, differentiating between joint sounds as a click/pop or crepitation) Three readings were performed on each participant. Collected data were checked, entered and statistically analyzed to test different variables by chi-square test with the level of significance (p< 0.05). Results: There were statistically significant association between joint sounds with regarding to bruxism and age, which showed the higher prevalence rates of joint sounds were found in children aged eight to ten years in comparison to those aged sex and seven years. However, there were statistically insignificant association between joints sounds and type in relation to gender. Conclusion: The bruxism in children may be associated with the symptoms of joint sounds with significant association regarding to age.

La cronología del yacimiento protohistórico de Cancho Roano (Zalamea de la Serena, Badajoz, España): dataciones radiocarbónicas, meseta de Hallstatt y efecto madera vieja
Authors: Mederos Martín Alfredo , Jiménez Ávila Javier
Published: December 2020

Este trabajo revisa dos series de dataciones radiocarbónicas del yacimiento protohistórico de Cancho Roano (Extremadura, España) obtenidas por el Instituto Rocasolano (CSIC) y el Laboratorio de Radiocarbono de la Universidad de Barcelona (UBAR) entre 1978 y 1987. Las fechas del CSIC se encuentran dentro del rango cronológico que los materiales arqueológicos establecen para la secuencia del yacimiento (en torno al s. V a.C.), pero las de la UBAR, más numerosas, presentan una gran dispersión, afectadas por la meseta de Hallstatt y el uso de carbón de madera, que dificulta su lectura y su encaje cronocultural, lo que ha provocado que hasta ahora no se hayan integrado en los debates científicos sobre el yacimiento.

Celeberrimo Sisaponensi regione in Baetica miniario metallo… Vías de investigación sobre el cinabro hispano en época romana
Authors: Zarzalejos Prieto Mar , Esteban Borrajo Germán , Hevia Gómez Patricia , Pina Burón María Rosa
Published: December 2020

El cinabrio (HgS) en época romana fue un producto muy apreciado por su uso como pigmento rojo en la pintura mural, convirtiéndose, gracias a su elevado precio, en un indicador de estatus. Pero sus aplicaciones no acaban aquí, dada la capacidad del mercurio (Hg) para amalgamar metales nobles, lo que explicaría el férreo control de la explotación y gestión del mineral por el Estado romano. Su papel en la economía antigua se ha analizado tradicionalmente desde la interpretación de las fuentes escritas, pero la aplicación de técnicas arqueométricas sobre diferentes objetos de estudio abre nuevas vías para dimensionar su producción y difusión. En esta tarea colabora también el estudio diacrónico de la ciudad que gestionó su beneficio -Sisapo- y la investigación sobre su territorio de explotación. En este trabajo se sintetiza el avance en el conocimiento sobre estos tópicos de investigación realizados en el marco del proyecto Sisapo, iniciado por Carmen Fernández Ochoa y en el que ha trabajado desde sus inicios.
Inscripciones altomedievales sobre una basa romana hallada en el sector de Puerta Obispo (León)
Authors: Morillo Cerdán Ángel , García Marcos Victorino
Published: December 2020

durante las excavaciones desarrolladas en 1996 en el sector de Puerta Obispo, situado junto a la puerta oriental del recinto romano y medieval de la ciudad de León, se encontró una basa romana que en época altomedieval fue reutilizada como capitel de una pilastra adosada a un muro, como demuestra la presencia de varias inscripciones religiosas en tres de sus caras. Los epígrafes indican que dicho capitel formó parte o estuvo en las proximidades de un sagrario o altar de una capilla relacionada posiblemente con la catedral prerrománica erigida a comienzos del siglo X y que sufrió graves daños por los ataques andalusíes de finales de esa centuria a León. La estratigrafía confirma la amortización del capitel a finales del siglo X o primera mitad del XI. Este marco temporal coincidiría con desescombro tras dichos ataques o el derribo de la catedral prerrománica para erigir la románica a partir de 1073.

Three Steps Towards the Phenomenology of Literature with Arūnas Sverdiolas
Authors: Levina Jūratė
Published: December 2020

The paper outlines the methodological orientation of Arūnas Sverdiolas’s scholarship and his school towards the praxis of the hermeneutic understanding of concrete cultural phenomena and takes this approach into the field of the phenomenology of literature. The attempt begins with a definition of the literary work in the hermeneutic framework of discourse, in which the work is considered to be an utterance that expresses an originary grasp of world phenomena. This capacity of the work to express is enabled by the operative mechanism of discourse, which binds, by the means of grammar and reference, the linguistic form of the work to the intentional structure of experience. To show this mechanism at work, the paper looks into Alfonsas Nyka-Niliūnas’s project of self-creation: Sverdiolas examines the poet’s diaries to reconstruct his effort of cultivating his poetic ego along the hermeneutic lines of the existential time, while Nyka-Niliūnas himself expresses this self-conception poetically as a more general phenomenon – the phenomenon of poetic self-consciousness as such – in the poem “Autobiography 1986”.

The reliability of causal inference from data (by independence-based methods) is analyzed. We uncover some mechanisms which may result in model inadequacy due to sample bias and hidden variables. We detect some specific problems in recognition of direction of influence when some causes are hidden. Incorrectness of known rule for edge orientation (under causal insufficiency) is revealed. We suggest the correction to the rule aiming to retain model adequacy.

One of the most common tasks that arise in building intelligent machine vision systems for intellectually autonomous machines is the problems of classification and regression. Classification problems are used for the reflexive action of autonomous machines. Prediction tasks can be used to build machine vision systems to provide intelligent autonomous machines with environmental knowledge, which in turn is important for planned predictable movements. Defining a class of task instances is an important procedure for the effective design of deep learning systems. In this context, the possibility of using a multilayered neural network as a regressor to construct elementary functional mappings is explored for further prediction. The study outlines the peculiarities of functioning and configuration of a specialized robotics system, considered in this paper as an intelligent autonomous machine or physical agent, generates a set of data points for elementary functions, analytical modeling and modeling of training systems. Input graph was constructed, neural network architecture was defined, gradient descent algorithm was implemented, and output schedules were finally constructed: learning process, results prediction and comparative graph of predicted results superimposed on the input graph. As a result of the study, an assessment of the machine's intellectual ability to predict was made.
O espiritografista contemporâneo
Authors: Krause de Campos Maria Idalina , Rodrigues Dinarte Luiz Daniel , Corazza Sandra Mara
Published: December 2020

O texto dá a ver um fazer poético tradutório espiritográfico possível na educação contemporânea. Defende que o espiritografista ocupa três lugares funcionais e de auto formação constante – do estudante, do escritor e do educador (EEE) – em laboratório próprio e singular que age através da variação de si. Toma o método espiritográfico como agente capaz de movimentar corpo-espírito-mundo, para realizar processos tradutórios didáticos no espaço da aula. Utiliza-se dos variados procedimentos de escrita do pensador e poeta Paul Valéry e os transforma em processos experimentais e literários que ativam o eu-empírico de um espírito aventureiro que lê e escreve. Mostra e conclui que o professor-pesquisador, ao valer-se dos procedimentos de tal método, dissemina aventuras didáticas do desejo de educar, transcriando por esta via a realidade curricular.
A literatura enquanto práxis educativa emancipatória e as possibilidades formativas dos Bildungsroman
Authors: Oliveira Neiva Afonso , Amaral Filho Fausto dos Santos
Published: December 2020

O texto discute o modo de compreensão dos Bildungsroman, da arte e da formação humana nos formatos da Bildung alemã. Levanta questões, em primeiro lugar, sobre os caminhos que a racionalidade moderna foi tomando, com prejuízo da arte e da filosofia como maneiras do conhecer realizar-se. Em segundo lugar, e tendo presente o que foi dito relativamente às necessidades de produção de sentido para além do que é racional, detecta-se que a literatura pode exercer um papel fundamental para a formação humana. Ainda que pensemos que, em última instância, toda a literatura é formativa, debruçamo-nos sobre um caso emblemático: os romances de formação, dimensões literárias da formação do eu. Como caso exemplar de literatura que descreve, retrata a formação do sujeito, ainda na segunda parte do texto, trazemos uma abordagem sobre os Bildungsroman como oportunidade de resgate entre o que se perdeu na modernidade em termos de uma subjetividade que aflorara, apesar do progresso das ciências e do avanço da técnica. O texto traz como conclusão a necessária ênfase nos processos formativos que promovam os interesses integrais da multiplicidade das possibilidades humanas, entre eles, a emancipação dos sujeitos.

Published: December 2020

This paper is an analysis and systematization of modern research in the field of cyber-physical system information security. The problematic issues of information security of such systems are considered: «what is being attacked?», «who is attacking?», «why is someone attacking?», «how is someone attacking?» and «how to protect the system?». As an answer to the first question, the paper proposes a definition and classification of cyber-physical systems according to such criteria as complexity, connectivity, criticality and social aspect. As an answer to the second and the third questions, the paper describes a classification of attacker according to such criteria as type of access, method of access, intentions, knowledge and resources. As  an answer to the fourth question, the paper contains a classification of attack actions according to such criteria as subject and object, method of influence, prerequisites and consequences. As an answer to the fifth question, the paper proposes a classification of protection methods and security tools according to such criteria as principle of operation, object of protection and task to be solved. The scientific significance of the paper is systematization of a current state of the art in the subject area. The practical value of the paper is providing information about security issues that are specific to cyber-physical systems, which will allow one to develop, manage and use such systems in a more secure way.

Haemagglutination assay and haematological analysis of 143 poults generated as F1 individuals by artificial insemination from randomly selected turkeys of White, Black and Lavender genotypes which are classified by antibody titre was carried out so as to confirm their antibody titre levels in response to sheep red blood cells (SRBC). Results showed that mean values obtained for high and low antibody titres were 7.31 and 2.67 respectively, resulting in the classification of the turkeys into Black high and low, Lavender high and black, and White high and low antibody titres. The genotype’s titre had significant (P <0.05) effect on the packed cell volume (PCV), haemoglobin (Hb), red blood cells (RBC), white blood cells (WBC) and basophil (BAS) of the basal haematological parameters. Genotype’s titre had no significant (P >0.05) effect on the primary response haematological parameters. Meanwhile, the primary response haematological parameters to SRBC antigen varied along the genotypes with the WBC increasing drastically in all the genotypes, signifying the presence of an antigen. The study concluded that the F1 turkey poult population studied diverged along the high and low antibody titre in response to SRBC. Thus, the F1 generation of the high antibody titre genotypes (Black high, White high and Lavender high) can be used as foundation stock for selection of local turkeys for high antibody titre.

Published: December 2020

Alginate beads attract attention as a encapsulation matrix of bioactive substances in food. However, the stability of beads depends on calcium ion and sodium alginate concentration, gelling time and others factors. The aim of this study is to investigate the influence of different types of calcium salts on the structural and mechanical parameters - the rupture force and rupture deformation at different gelling times of the pear jam prepared with soluble dietary fibers and inulin. The relationships between the rupture force and rupture deformation of the fruit jams were established. By increasing the gelling time from 24 hours to 48 hours, the rupture deformation of jams with 7% calcium lactate were reduced and in those with 7% CaCl2 the rupture forces increases. Any change in rupture force was observed for the jam with 3.5% CaCl2. This study demonstrated the practical application of different calcium salts for preparation of stable pear jam.

Phomopsis viticola (Sacc.) Sacc. (syn. Cryptosporella viticola Shear, Diaporthe viticola Nitschke, Diplodia viticola Desm, Fusicoccum viticolum Reddick, Phoma flaccida Viala & Ravaz, Phoma viticola Sacc.), is the causal agent of the grapevine disease named ‘Phomopsis cane’ and ‘Leaf spot’ in the U.S.A. or ‘Excoriose’ in Europe. This study aims to evaluate the influence of the microclimate on Phomopsis viticola attack in Aiud-Ciumbrud vineyards. The observations were done on four plots in Aiud-Ciumbrud vineyards in the period March-August 2020. Up to the end of August 2020, ten treatments with contact and systemic products based on metiram and sulphour were done together with the other standard agro-technological operations. In the ecological conditions of spring-summer 2020, with higher temperature than the average in January, February, March and June, more rain than the average in February, March and June and less rain in January, April and May, we found frequency of the excoriosis in the range of 4%-12% at the beginning of the season. After the fungicide treatments, the attack frequency decreased up to 0%-7%. In the present research work, we show that in Aiud-Ciumbrud vineyards Phomopsis viticola attack was present and influenced by the microclimate conditions and also it was reduced by the fungicide treatments.
