UV-light-driven cadmium sulphide (CdS) nanocatalysts: synthesis, characterization, therapeutic and environmental applications; kinetics and thermodynamic study of photocatalytic degradation of Eosin B and Methyl Green dyes
Authors: Ali Sundas , Akbar Jan F. , Ullah Rahat , Wajidullah  , Ullah Naimat , Salman
Published: December 2021

Cadmium sulphide (CdS) nanoparticles (NPs) were synthesized through hydrothermal route and characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), Energy dispersive X-ray analysis, Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy and Thermo gravimetric analysis (TGA).The band gap of CdS nanoparticles was found to be 2.38 eV. CdS NPs are crystalline aggregates with hexagonal structure as shown by SEM and XRD analysis. TGA study revealed that the synthesized nanomaterials were very stable to temperature and only 6.54% total loss occurred during heating range (25 °C–600 °C).The CdS NPs were used for the first time against the degradation of Eosin B (EB) and Methyl green (MG) dyes in aqueous solution.The degradation of EB and MG over CdS nanocatalysts followed second order kinetics. The predicted activation energies for both the dyes' reactions were 61.1 kJ/mol and 32.11 kJ/mol, respectively. About 95% and 90% dye degradation was observed at the time interval of 160 minutes for EB and MG, respectively. High percent degradation of EB was observed at high pH (pH 0) while at low pH (pH 4) high percent degradation was found for MG dye. Maximum dye degradation was found at the optimal dose (0.03 g/L) of the catalyst and at low dye concentration. The rate of EB and MG dye degradation was found to increase with increase in temperature up to 45 °C. The recyclability study showed that CdS nanoparticles could be reused for the degradation of the given dyes. Good antibacterial activity against Staphylococcus aureus was shown by CdS NPs. From the biocompatibility it was confirmed that CdS NPS are bioincompatible compatible.

RESUMO

 

O presente artigo propõe uma reflexão acerca da importância do ensino da literatura dentro de uma proposta pedagógica na Educação Infantil preocupada com a Educação das relações étnico-raciais no Brasil. Ademais, busca pensar a formação do leitor literário numa perspectiva identitária para a promoção de uma Educação antirracista continuada. O trabalho reúne os seguintes aportes teóricos: Cosson (2012), Bordini e Aguiar (1993), Brasil (2004; 2017), Munanga (2005), entre outros. Quanto à metodologia, consiste em uma pesquisa bibliográfica e uma análise descritiva das seguintes obras literárias infantis: Amoras (2018), de Emicida, e Meu crespo é de rainha (2018), de bell hooks[1]. Conclui-se que esta pesquisa se torna relevante uma vez que segue as determinações da Lei 10.639/2003, que alude à obrigatoriedade do ensino da questão étnico-racial, temática que carece mais atenção na Educação Básica, desencadeando e propondo atender a questões presentes no ensino na Educação Infantil, oferecendo possibilidades por meio da literatura para um letramento étnico-racial efetivo e precoce.

ABSTRACT

The present article aims at discussing the importance of teaching literature for children within the scope of a pedagogical approach concerned with ethnic-racial relations education, from children`s education on, in Brazil. Furthermore, it aims at thinking about the literary reader`s literacy according to an identity perspective so that it promotes antiracist education over the time. The paper brings the following authors together: Cosson (2012), Bordini e Aguiar (1993), Brasil (2004; 2017), Munanga (2005), among others. It consists of a bibliographical survey approach and a descriptive analysis of the following children books: Amoras (2018), by Emicida, and Meu crespo é de rainha (2018), by bell hooks. The relevance of the work lays on the fact it has followed Federal Law n. 10.639/2003, which has imposed the teaching of ethnic-racial issues in Brazil. This theme wants to be given more attention in Basic Education so that it answers issues that are present in early education, in order to offer children many possibilities through literature to ethnic-racial effective and early literacy.

 

Keywords: Training of readers; childhood education; representativeness; ethnic-racial literacy.
Gêneros textuais e sequência didática: ferramentas para o desenvolvimento das práticas sociais de leitura e de escrita numa perspectiva sociodiscursiva
Authors: De Sousa Martins Suely , de Oliveira Luiz Henrique , Nonato da Silva Salviano Raimundo , França José Marcos Ernesto Santana de
Published: December 2021

O ensino de Língua Portuguesa ainda é problemático, principalmente, no que diz respeito em desenvolver no alunado as habilidades de leitura e de escrita de forma proficiente, como pretendem os documentos oficiais PCN e BNCC. Em vista disso, defendemos que os gêneros textuais, quando mediados por práticas pedagógicas significativas, podem atuar no desenvolvimento das capacidades de linguagem, bem como podem despertar o interesse do aluno para a aprendizagem e desenvolvimento das habilidades de leitura e de escrita, evidenciando que essas atividades educativas não estão apenas dentro da sala de aula, mas que se configuram como instrumentos para o exercício de cidadania no mundo real e no convívio social. Sendo assim, este trabalho tem como objetivo discutir e apresentar os gêneros textuais e a sequência didática como ferramentas para o desenvolvimento da leitura e da escrita como práticas sociais e discursivas de linguagem para o exercício sociopolítico de cidadania. E para ilustrar como isso é possível, propomos uma aplicação didático-pedagógica, ou seja, um uso prático com o gênero textual notícia, explorando o processo de retextualização de um poema em uma notícia. Essa perspectiva de abordagem de ensino de língua segue a orientação teórico-metodológica do Interacionismo Sociodiscursivo (ISD), a partir de autores como Bronckart (1999), Schneuwly e Dolz (2004).
O ensino de morfologia na educação básica: algumas reflexões e propostas
Authors: Araújo Oliveira Fábio
Published: December 2021

Neste trabalho, buscamos refletir sobre a cena contemporânea do ensino de morfologia no Brasil, na educação básica, e, a partir daí, propor atividades que privilegiem o funcionamento da gramática no texto. O nosso trabalho está inserido no campo da Linguística Aplicada, por ser uma área interdisciplinar que aborda questões de ensino e aprendizagem de línguas. Nesse sentido, refletimos sobre contribuições da Linguística Textual e da Análise do Discurso para teorias e documentos que provocaram uma mudança na perspectiva de compreender o ensino de gramática. Concluímos que há um descompasso entre teorias pedagógicas e práticas de ensino quanto ao trabalho com a gramática na escola, inclusive no campo da morfologia, por isso se faz necessário contribuir com reflexões e propostas nessa área.
Uma Proposta linguística de classificação de constituintes morfológicos que compõem formas verbais latina
Authors: Chain Soraya Paiva , De Lima Serudo Victor
Published: December 2021

Tomando como base a comutação que se faz no eixo paradigmático para a identificação e classificação de morfema (SAUSSURE, 2012, p. 171-175) e (CASTILHO, 2010, p. 46-48), inquietamo-nos quanto à classificação apresentada nas Gramáticas Latinas, a respeito de alguns constituintes (vogal de ligação, desinência modo-temporal e desinência número-pessoal), em determinadas conjugações. Por conta disso, apresentamos este estudo, no qual discutimos a classificação de alguns constituintes, com base na Teoria Estruturalista – que estuda a estrutura e a formação dos vocábulos, colocando o morfema no centro da análise –, para demonstrarmos todos os morfemas/elementos que constituem cada forma (pessoa/modo-tempo/conjugação) verbal latina da diátese ativa, nos tempos do infectum, e, com isso, apresentarmos uma proposta de classificação de alguns constituintes verbais latinos, condizente com estudos linguísticos modernos.
Leitura e escrita como práticas de resistência: construindo agenciamentos na escola
Authors: De Queiroz Atauan Soares , De Freitas Dias Juliana
Published: December 2021

Este artigo propõe considerações reflexivas sobre discursos e práticas de (micro)resistência crítica e criativa relacionadas ao debate sobre gênero social no contexto escolar. Para delinear traços da conjuntura global, inicialmente, apresenta os pressupostos que sustentam os discursos conservadores no campo da educação, considerando suas conexões com processos históricos e socioculturais. Em seguida, aborda práticas de (micro)resistência no contexto do EM que envolvem práticas de leitura crítica e produção de textos autorais marcados por discursos antissexistas, tomando como referência as experiências sociopedagógicas construídas no Projeto Mulheres Inspiradoras. Por fim, coloca em evidência as práticas de escrita autoral que concorrem para a reelaboração reflexiva e identitária e para a cidadania ativa. Em termos de microanálise, mobiliza categorias linguístico-discursivas do significado acional do discurso (FAIRCLOUGH, 2003), especificamente a intertextualidade e a pressuposição, que apontam para agenciamentos sociodiscursivos por parte dos/as estudantes.
Os territórios do hospício e o domínio da loucura na imaginação literária de Guillermo Rosales
Authors: De Moura Isaque
Published: December 2021

A trajetória biográfica do escritor cubano Guillermo Rosales é atravessada por um extenso histórico de violência, desajustes e frustrações. Perseguido por vozes e visões que o atormentavam, Rosales foi diagnosticado com esquizofrenia ainda durante a adolescência, tendo passado por diversas instituições psiquiátricas ao longo da vida. Parte dessas experiências estão expostas em sua obra de maior destaque, o romance Boarding Home, publicado originalmente em 1987. No livro, Rosales dá voz a seu alter ego, o protagonista William Figueras, escritor exilado da ilha de Cuba que narra sua rotina na condição de interno em um sanatório particular nos Estados Unidos. O personagem expõe os abusos, as situações precárias do hospício e as constantes agressões físicas e psicológicas às quais ele e outros pacientes são submetidos, descrevendo um cenário no qual os sujeitos tornam-se progressivamente despojados de individualidade. Assim, tomando como referência o espaço asilar do manicômio e seu contexto de aniquilação de subjetividades, este artigo busca refletir sobre as dinâmicas de deterioração identitária no mundo do internado e os processos de desfiguração pessoal aplicados ao regime de confinamento na home. Nessa perspectiva, mobilizam-se os pressupostos teóricos do sociólogo canadense Erving Goffman (1987), nas discussões acerca das instituições totais, e os principais mecanismos de mortificação associados a tais estabelecimentos. As análises foram realizadas com base na edição original do romance, publicada pela editora espanhola Siruela, em 2003. Argumenta-se que a Boarding Home, enquanto suposta casa de saúde mental, desvia-se gravemente de sua finalidade terapêutica, na medida em que os personagens incorporam e reproduzem a violência da estrutura institucional que os suplicia. Nessas circunstâncias, compreende-se que o espaço manicomial não opera como local de acolhimento ou cuidado, mas como engrenagem de opressão, abandono e extermínio de vidas humanas.
Práticas de letramento, tecnologias digitais e gêneros discursivos no ensino médio técnico
Authors: Batista Júnior José Ribamar Lopes , Peixoto Gercivaldo Vale , Lima-Neto Vicente
Published: December 2021

Embora sejam um conceito discutido desde a década de 1990 na área acadêmica brasileira, as práticas de letramento (BARTON, 2007) não têm tido grande destaque nas salas de aula de língua portuguesa, mesmo sendo enfatizadas desde os PCN, há mais de vinte anos. Atrelada a esta questão, está a ineficiência curricular e pedagógica do uso de tecnologias digitais na escola, que ainda insiste em se manter mais tradicional e marginalizar tecnologias que são utilizadas todo dia pelos alunos da educação básica (COSCARELLI, 2016; RIBEIRO 2016). É sobre essa temática que este relato de experiência, de natureza descritiva e interpretativa, se debruça, o qual objetiva-se apresentar como o Laboratório de Leitura e Produção Textual do Colégio Técnico de Floriano/UFPI tem desenvolvido projetos de letramento que envolvem tecnologias digitais em propostas de leitura e produção textual, com o fim de enaltecer o protagonismo juvenil. Metodologicamente, selecionamos dois projetos específicos, intitulados “Quer que eu desenhe?” e “Cais Cultural”, ambos envolvendo o uso de tecnologias. Os resultados apontam para um aumento das capacidades linguísticas orais e escritas, melhoria no uso de tecnologias digitais e um bom desenvolvimento de habilidades de convivência social.
O caráter linguístico regional-popular da poesia de Ascenso Ferreira
Authors: Sá Edmilson José de
Published: December 2021

Este artigo tem por objetivo apresentar uma reflexão sobre o regionalismo na literatura popular pernambucana. Para tanto, o corpus foi construído a partir de poemas do escritor Ascenso Ferreira, pelo fato de o autor pertencer a uma geração de escritores preocupados com a linguagem, a literatura e os problemas da sociedade em transição. As marcas regionais encontradas em seus poemas serviram de aproximação com a realidade do leitor. Por isso, para entender um pouco sobre a maneira como a sua linguagem se manifesta nos poemas modernos de cunho regionalista, optou-se por analisá-los sob os pontos de vista lexical e morfossintático. Percebeu-se, com a análise, que os exemplos de lexias simples, expressões idiomáticas e construções de tradição oral são comuns na linguagem espontânea falada em Pernambuco, mas que também podem ser encontradas em outros estados do Nordeste, o que só ratifica a importância de estudos dessa natureza, cujo propósito mais amplo é entender além da “cor local” do falante, a heterogeneidade da língua que ele fala.
Denominações para o “homossexual masculino” no ALiMA: lendo e discutindo imagens sociais
Authors: Silveira Theciana Silva , Serra Luís Henrique
Published: December 2021

Neste texto, busca-se mostrar como a análise do léxico pode ser um importante caminho para desvelar conceitos e imagens sociais cristalizadas e pode contribuir para discutir padrões sociais vigentes. Nesse sentido, a pesquisa centra-se na hipótese de que as denominações dadas ao homossexual masculino resultam de uma ideologia dominante com relação à imagem e à sexualidade do homem na sociedade. O estudo foi feito com base em um conjunto de dados lexicais coletados para a produção do Atlas Linguístico do Maranhão (ALiMA) e conta com um total de 29 denominações. O estudo ancora-se nas discussões de campos teóricos como a História da Sexualidade e a Linguística. Neste último campo, o trabalho fundamenta-se nos estudos das Ciências do Léxico, da Dialetologia e da Geolinguística. Os dados foram organizados em tabelas e em grupos de denominações dicionarizadas ou não, em seguida, foram analisados no sentido de tentar reconstruir valores e imagens do homossexual no imaginário popular. Os dados mostram que as denominações dadas ao homossexual masculino muitas vezes estão relacionadas à aspectos físicos e sexuais do homem gay e, também, tem como base uma ideologia heteronormativa que ainda predomina na sociedade. Desse modo, é possível concluir que, muito embora haja uma intensa discussão sobre padrões existentes na sociedade, ainda há um longo caminho para a desconstrução dessas imagens idealizadas.
Os Ethé do parecerista de pareceres publicados na revista Encontros Bibli
Authors: Sipavicius Seide Márcia
Published: December 2021

Observa-se, a partir de 2003, uma proliferação de revistas científicas on line no Brasil fomentada pelo uso da plataforma Open Journal System cuja versão em língua portuguesa foi fomentada pelo IBICT como uma primeira etapa do movimento da Ciência Aberta. Etapas posteriores desse movimento inclui a abertura do processo de avaliação dos artigos entre outras como o compartilhamento de dados primários e o depósito antecipado de artigos em repositórios de pré-print. Como consequência da implementação desta agenda existem revistas que publicam pareceres o que oportuniza que este gênero seja melhor descrito e conhecido. Neste contexto, este artigo analisa o ethos (a imagem de si) do autor de parecer publicado mediante identificação dos recursos linguísticos e das estratégias retóricas empregadas para tanto. Na primeira seção, apresentam-se as teorias nas quais a pesquisa se embasa, a Linguística Funcional e a Retórica, e alguns estudos anteriores sobre o assunto; na segunda seção, descrevem-se a metodologia empregada para a constituição do corpus formado por 10 publicados na revista Encontros Bibli em 2019 e em 2020; na terceira seção, há a identificação e descrição das estratégias empregadas no corpus para constituição do ethé do pareceristas e, ao final, são feitas considerações finais sobre as contribuições e limitações da pesquisa. As qualidades do ethos clássico, segundo Aristóteles se centram na equidade, no senso de justiça, imparcialidade, isenção e neutralidade. Os resultados da análise da amostra de pareceres mostram que o contexto da avaliação de artigos científico, os ideais da Ciência Aberta e a imagem de si buscada pelos pareceristas dos pareceres do corpus analisado reconfiguraram as qualidades apontadas pelo filósofo em três ethé: a do parecerista objetivo de neutro, a do parecerista respeitoso, polido e educado e a do parecerista democrático e aberto.
Poder e humor em tempos de pandemia as deepfakes de Brunno Sarttori

Em que medida o humor pode ser considerado como exercício de poder? Em tempos de pandemia, o que há de revolucionário nesse humor que enseja um riso contra o alto escalão do governo de um país? Essas são questões gerais que abordo neste artigo, tomando como material de análise dois vídeos produzidos/assinados por Brunno Sarttori. O objetivo é ilustrar a tese de humor como prática de resistência a partir do tema da Covid-19, sobretudo a partir de um procedimento clássico no campo discursivo do humor: a paródia.
Genomics of Pulmonary Hypertension
Authors: Welch Carrie Lynn , Chung Wendy K.
Published: December 2021

Background -

Pulmonary hypertension (PH), defined by mean pulmonary artery pressure >20 mmHg, is a common physiologic manifestation of many diseases. Pulmonary arterial hypertension (PAH) represents a smaller subgroup of patients who have PH, and PAH causes significant cardiorespiratory morbidity and premature mortality. PH can manifest across the lifespan, with similar incidence for both pediatric- and adult-onset disease. However, pediatric-onset disease is particularly challenging because it is frequently associated with a more severe clinical course and comorbidities including lung and heart developmental anomalies. For PH Group 1/pulmonary arterial hypertension, causal genetic variants can be identified in ~13% of adults and ~43% of children.

Clinical implications –

Education about the option for genetic testing is strongly recommended for all pediatric and adult HPAH/IPAH patients. Both gene panel and exome/genome sequencing tests can be useful in diagnosis, but exome/genome sequencing provides a comprehensive dataset for reanalysis over time for cases without an initial diagnosis. Knowledge of genetic diagnoses can immediately impact clinical management of PH, including multimodal medical treatment, surgical intervention, transplantation decisions, and screening for associated conditions.

Conclusions -

There is a need for large, diverse, international consortia with ever-improving analytical pipelines to confirm previously implicated genes, identify additional genes/variants, assess penetrance, and clinically characterize each genetic subtype for natural history, prognosis and response to therapies to inform more precise clinical management.
Psychic wholeness in the context of Anna Terruwe and Conrad Baars’ theory of repressive neuroses
Authors: Lipska Anna
Published: December 2021

In the 1970s, two Dutch psychiatrists, Anna Terruwe and Conrad Baars, developed an innovative theory and therapy of repressive neuroses. Their theory was founded on the philosophical anthropology of Saint Thomas Aquinas. This approach to neuroses stemmed from the observation that contemporary psychiatry and psychology lacked philosophical underpinnings and that sciences thus formed were unable to help people. The key concept in the theory of repressive neuroses is psychic wholeness—the unity of the senses, the intellect, and will under the natural guidance of the last two of these. Stressing the great importance of this wholeness of human sensory and intellectual faculties for mental health has its consequences in the approach to and treatment of repressive neuroses. Every neurotic disorder is a kind of disintegration (repression of emotions and lack of intellectual control); therefore, the therapeutic process is supposed to effect a reintegration of distinct human faculties. The article presents the concept of psychic wholeness in the context of the theory of repressive neuroses, with special focus on Aquinas’ anthropology as the philosophical basis for this theory. Bowen’s concept of differentiation of self is also discussed and its similarities to psychic wholeness are pointed out.
Uważność i jej pomiar
Authors: Radoń Stanisław
Published: December 2021

Uważność może być rozumiana jako stan lub cecha. Z tego powodu istnieje wiele niejasności, które wynikają głównie z braku precyzji dotyczącej zakładanego modelu uważności. Podobne rozbieżności dotyczą stosowanych narzędzi badawczych służących do pomiaru nasilenia uważności. Jak dowodzą liczne badania, narzędzia te mierzą nieco odmienne konstrukty psychologiczne. Dlatego badacze coraz częściej podejmują próby wyróżnienia oraz bardziej precyzyjnego rozdzielenia dwóch odmiennych aspektów uważności, tj. cechy i stanu, oraz opracowania na tej podstawie bardziej trafnych narzędzi badawczych. Niniejszy artykuł to przegląd istniejących miar uważności, z uwzględnieniem polskich adaptacji i ukazaniem ich specyfiki.
Kontrowersje wokół pojęcia trafności

Published: December 2021

W artykule zrelacjonowano zmieniające się na przestrzeni ponad 100 lat koncepcje pojęcia trafności pomiaru testowego. Aktualnie pojęcie trafności odnosi się do stopnia, w jakim dane empiryczne oraz teoria uzasadniają interpretację wyników testowych w zakładanym kierunku (American Educational Research Association, American Psychological Association, National Council on Measurement in Education [AERA, APA, NCME], 2007, s. 31). Przedstawiono 5 podstawowych źródeł danych dotyczących trafności oraz problemy związane z integracją dowodów na rzecz trafności w spójną argumentację. Podkreślono użyteczność zaproponowanego przez Kane’a podejścia do walidacji opartego na argumentacji, odwołującego się do logiki nieformalnej i struktury argumentu wprowadzonej przez Toulmina. Omówiono także różnice stanowisk zajmowanych przez badaczy w odniesieniu do 2 podstawowych kwestii: czemu przysługuje trafność i jaki jest właściwy sposób jej ustalania?
A Rare Case Report of Inguinal Herniation with Urinary Bladder as its Content
Authors: Pawar Samadhan , Borde Chaitanya , Patil Atul , Ramesh Yasam Venkata , Nagarkar Raj
Published: December 2021

Background:

Although inguinal hernias are common, cases of inguinal hernia involving the bladder were observed to be very rare (<5%). Diagnosis of Inguinal
Bladder Herniation (IBH) is very challenging, and it was reported to be identified only in ≤10% of cases prior to an operation and ≤20% during
surgical intervention. The majority of the patients are asymptomatic or have non-specific symptoms, making the condition difficult to diagnose
pre-operatively. In many cases, the condition is usually diagnosed intraoperatively. Therefore, diagnosis, surgical planning, and careful
management can play a vital role in avoiding any unwanted complications.

Case Presentation:

In the present case, a 60-year-old male patient with a known history of malignancy was presented to our hospital without any symptoms related to
inguinal hernias.

Conclusion:

During his routine check-ups, the patient was fortuitously diagnosed with IBH. The patient underwent surgery, and the defect was repaired using
Bassini hernioplasty without any complications. Postoperative recovery was uneventful. On follow-up, no pain or urinary-related symptoms were
reported.
Immunotherapeutic Approaches for the Treatment of Neurodegenerative
Diseases: Challenges and Outcomes
Authors: Mondal Amal Chandra , Sushma
Published: December 2021

Background:

Neurodegenerative diseases, being rapidly increasing disorders and the
seventh leading cause of death worldwide, have been a great challenge for researchers, affecting
cognition, motor activity and other body functioning due to neurodegeneration. Several neurodegenerative
diseases are caused by aggregation of proteins which induce the alteration of neuronal
function leading to cell death. These proteins are amyloid-β peptide, tau, α-synuclein, and mHTT,
which cause Alzheimer’s disease, Frontotemporal dementia, Corticobasal degeneration, Progressive
supranuclear palsy, Parkinson’s disease, Multiple system atrophy, Dementia with Lewy-body
and Huntington’s disease. Currently available treatments only reduce symptoms and increase life
sustainability; however, they possess side effects and are ineffective in curing the diseases.

Objectives:

Literature survey of neurodegenerative diseases and immunotherapeutic approaches is
used to evaluate their pharmacological effects and future endeavours.

Methods:

A literature search was performed to find the relevant articles related to neurodegenerative
diseases and immunotherapies. Clinical trials data were analysed from clinicaltrial.com.

Result:

According to literature study, it was found that researchers have explored the effect of active and passive vaccines generated against amyloid-β, tau, α-synuclein and mHTT. Few clinical trials have shown severe side effects and terminated, despite of that, few of them produced desirable effects for the treatment of AD and PD.

Conclusion:

Several immunotherapeutic trials have shown promising outcomes against amyloid-β,
tau and α-synuclein. In addition, various preclinical studies against mHTT and prion proteins are
under scrutinization. These clinical outcomes indicate a promising role of immunotherapies against
neurodegenerative diseases.
Residual Magnetic Moment Influences the Features of Fe3s XPS Spectrum:
A Case Study
Authors: Sahu Ranjan K.
Published: December 2021

Background:

Fe 3sXPS spectrum exhibits doublet peak instead of predicted singlet
peak based on spin-orbit coupling theory. This anomalous behavior is considered to be of magnetic
origin. However, the effect of residual magnetic moment on the features of Fe3s doublet
peak is not understood fully.

Objective:

This study aims to verify the effect of residual magnetic moment on the spectral features
of Fe3s XPS spectrum of magnetic material.

Method:

As a case study, we have carried out a high-temperature XPS study of the Fe 3s spectrum
of magnetic domain aligned (MDA) sample with composition composed of SrFe10.8Al1.2O19.
In addition, the XPS data have been compared with the data acquired at different temperatures of
magnetic domain non-aligned (MDNA) sample.

Results:

The results show that the majority peak intensity and minority peak width of Fe 3s spectrum
of MDA are smaller than those of the MDNA sample, and they increase systematically with
increasing temperature. However, it is noted that the features of Fe3s spectrum of both MDA and
MDNA samples completely overlap near and above the Curie temperature, Tc ~ 670K.

Discussion:

The residual magnetic flux in the MDA sample alters the interaction between 3s
electrons and valence 3d spin. In addition, the presence of residual magnetic moment leads to deviation
of the escaped electrons from their path, therefore the majority peak intensity of MDA
sample becomes smaller than the MDNA sample at below the Curie temperature. Consequently,
the spectral features of MDA samples are different than the MDNA samples at below the Curie
temperature.

Conclusion:

The analysis of XPS data suggests that the residual magnetic moment influences the
spectral features of the Fe3s spectrum. These results provide evidence that it is important to consider
the contribution of the residual magnetic moment while deriving information from the Fe 3s
XPS spectrum of the MDA sample.
Chemical Sulphate Corrosion on Cement Composites in Various Model
Environments
Authors: Estokova Adriana , Kovalcikova Martina
Published: December 2021

Background:

Cementitious composites, which are subject to increasing demands, are
often exposed to various external attacks, such as aggressive groundwater and surface water,
chemicals in the soil, gas penetration, or phenomena related to water freezing and melting. One
of the most common reasons for the deterioration of cement composites is the corrosion process.
Corrosion results in irreversible damage that occurs during the chemical reaction of the material
with the components of the environment.

Methods:

The paper deals with experimental study of chemical sulphate corrosion of cement
composites prepared from three types of cement: ordinary Portland cement; sulphate-resistant
cement; and special hybrid cement, and industrial by-products and wastes: silica fume, zeolite
and a special mineral admixture based on blast furnace granular slag as cement partial substitutes.
Samples of cement composites were subjected to corrosion experiments in a sulphate environment,
which took place in the laboratory under model conditions for 180 resp. 270 days.

Results:

The deterioration parameters: changes in the weight and thickness of the samples, surface
and mineralogical changes, leachability of the basic components of the cement matrix as well as
changes in the liquid phase proved the degradation process due to chemical sulphate corrosion,
model solutions of H2SO4 with pH 3 and 4, and solution of MgSO4 with c (SO4
2 -) = 3 and 10 g /L.

Conclusion:

By comparing the leachability of the alkali components from cement composites, it
can be concluded that for the most aggressive model solution (H2SO4 with pH 3), both slagcontaining
formulations are the most stable in terms of the total ratio of leached calcium and silicon.
This finding is also supported by the results of water absorbency tests, which confirmed that
despite the increase in absorbency after chemical corrosion, cement composites with slag content
reach the lowest values.
choice of surgical tactics for the treatment of children with destructive pathological dislocation of the hip after hematogenous osteomyelitis
Authors: Djuraev Akhror Makhmutovich , Alpisbaev Khojaakhmed Shaykhislamovich , Tapilov Elyar Abduvalievich
Published: December 2021

A surgical approach to the treatment of destructive pathological dislocation of the hip in children has been substantiated, depending on age, the severity of destruction of the proximal femur and acetabulum. Reconstructive - restorative operations in most patients ensure the stability of the hip joint and thereby improve the patient's gait and statics, reduce the pelvic misalignment and eliminate the Trendelenburg symptom. The experience of surgical treatment of patients with pathological hip dislocations has shown that the most favorable outcomes are achieved with the use of open reduction of the stump of the head or neck of the femur with intertrochanteric detorsion shortening and varizing osteotomy with rotational pelvic osteotomy according to Salter and acetabular plasty according to Pemberton.

Objetivo: A restrição na participação é uma consequência significativa para indivíduos pós-Acidente Vascular Cerebral (AVC). No Brasil, não há instrumentos disponíveis que contemplem de forma abrangente a participação nesta população. Portanto, o objetivo deste estudo foi adaptar transculturalmente o Subjective Index of Physical and Social Outcome(SIPSO) para uso no Brasil. O SIPSO é um questionário com 10 itens, abrangendo questões de participação consideradas significativas para indivíduos pós-AVC. Métodos: O processo de adaptação transcultural envolveu as seguintes etapas: tradução, retrotradução, síntese das traduções, análise por um comitê de especialistas e teste da versão pré-final. Resultados: Observou-se equivalência semântica adequada entre as versões original e retrotraduzida. Durante a reunião de especialistas, foi realizada adequação dos itens às regras gramaticais da língua portuguesa. No teste da versão pré-final, em um item do instrumento foi reportada dificuldade de compreensão, sendo acrescentado um exemplo para ampliar a possibilidade de compreensão do item. Conclusão: O SIPSO-Brasil apresentou satisfatório grau de equivalência semântica, idiomática, cultural, conceitual e operacional. Contudo, estudos posteriores devem ser realizados para a continuidade da investigação da validade da versão adaptada do instrumento.

Objective: to identify the frequency of food consumption in children aged zero to 23 months. Methods: this analytical research with a quantitative approach was conducted with 911 mothers/guardians of children aged under 23 months. In data collection, sociodemographic information and information on the frequency of food consumption of the child in the last 24 hours were obtained through a questionnaire of food consumption markers from SISVAN. Results: more than two-thirds of the participants reported having offered inappropriate foods for the child's age the day before. Among children under six months of age, inadequate food consumption had a prevalence of 38.3%. In the age group from 6 to 23 months, this frequency of consumption was 88.4%. The most inappropriate foods consumed by children under six months of age were water/tea, fruit, and salty foods. Between the ages of six and 23 months, the consumption of non-breast milk, sugary drinks, stuffed biscuits, sweets, and candies predominated. Conclusion: the consumption of inappropriate foods for age was highly prevalent, especially in children above six months old.
The relationship between overweight and female infertility

Published: December 2021

Excessive weight seems to negatively influence fertility, and as it is a modifiable factor, understanding this relationship can contribute to infertility treatment. Adipose tissue is responsible for releasing several hormones and cytokines related to the reproductive system, such as leptin, TNF-a, and Interleukin-6, substances that can negatively impact female fertility. Additionally, a woman's diet and lifestyle can influence body weight and fertility. Food consumption, characterized by a high intake of foods with high energy density, high levels of sugar, saturated fat, and poor nutrients, as well as physical inactivity, can favor excessive weight. Thus, losing body weight obtained through a healthy diet associated with physical activity may restore fertility in overweight women.

Objective: To compare the prevalence of cardiovascular risk factors in university students from a Brazilian public higher education institution between three surveys. Methods: Cross-sectional surveys were conducted with 1,084, 1,085, and 1,041 university students in 2010, 2012, and 2014, respectively, from an institution located in Bahia, Brazil. Outcomes were cardiovascular risk factors: overweight, leisure-time physical activity for < 150 min per week, low consumption of fruits and vegetables, consumption of meat and chicken with fat, fried snacks, soft drinks or artificial juices, smoking, drinking alcohol abuse, and negative self-assessment of stress in life. The independent variable was the year of the survey.The measure of association was the Prevalence Ratio (PR). The significance level was 5%. Results: In all surveys, there was a higher prevalence of college students with insufficient leisure-time physical activity, low consumption of fruits and vegetables, consumption of fatty and savory meat, and negative self-assessment of stress. Overweight and consumption of chicken with fat increased over the years of the survey. Prevalence decreased in the last survey among college students concerning the consumption of fruits, vegetables, snacks, and artificial soft drinks or juices (PR: 0.66; 95% CI: 0.52–0.84). Conclusions: There was an increase in overweight; however, there were also positive modifications in eating habits among college students.

Published: December 2021

A Anemia de Fanconi (AF) é um distúrbio genético raro, herdado de maneira autossômica recessiva, e caracterizado por uma depressão medular progressiva, alterações morfológicas, como manchas café-com-leite, ausência de quirodáctilo, atrofia de genitália, hipogonadismo, baixa estatura, susceptibilidade a eventos mielodisplásicos, dentre outros. Trata-se de um paciente de 10 anos que procurou atendimento médico para avaliação de fimose e testículo retrátil bilateral. Verificou-se ausência do primeiro quirodáctilo direito, manchas café-com-leite e de fácies sindrômica, além de plaquetopenia e dores abdominais. O teste de fragilidade cromossômica confirmou a suspeita clínica de AF. A investigação é complexa e a clínica essencial para confirmação. O tratamento mais adequado é o transplante de medula óssea, podendo acarretar a cura dos sintomas hematológicos, como foi o caso em questão.

Objectives: to evaluate the association of the greater saphenous vein (GSV) diameter in the treatment of patients with severe chronic venous insufficiency (C6 CEAP classification) with ultrasound-guided polidocanol foam sclerotherapy (UGFS).  Methods: A prospective, descriptive and analytical study of 28 patients (30 limbs) that underwent UGFS. Patients were divided into 2 subgroups by GSV diameter (< 8 mm and ≥ 8 mm). Variables analyzed were ulcer healing, clinical intercurrences, clinical CEAP classification, Venous Clinical Severity Score (VCSS), diameter of the treated vein and presence of occlusion or recanalization by Doppler ultrasound. Patients were analyzed at the 1st, 3rd, and 6th months post-treatment. Results: The average age was 68.7 ± 10.5 years, 23 (82,1%) were women, and the average body mass index was 29.2 kg/m2. Although an improvement in VCSS score was observed during follow-up, no significant intergroup difference was noted. Seventeen (56%) limbs presented occlusion of the treated vein at the 1st month, 11 (36%) at the 3rd month, and 9 (30%) at the 6th month of follow-up. The ulcer healing rate was 56,6%. The average ulcer healing time was 90 days. Three (10%) patients presented with ulcer recurrence at the 6th month.  Survival analysis showed no significant difference in ulcer healing rate between subgroups after one year of follow-up (log-rank, p = 0,178). Conclusion: There was no difference between the subgroups of large and small VSM diameter in terms of symptom severity. However, significant reduction of VCSS and pain relief was observed after foam sclerotherapy.
Chronic obstructive pulmonary disease and atrial fibrillation
Authors: Glova S. E. , Razumovsky I. V.
Published: December 2021

Chronic obstructive pulmonary disease (COPD) has a close relationship with the development of heart failure and atrial fibrillation (AF). In the pathogenesis of AF in patients with COPD, decreased oxygenation, hypercapnia, pulmonary hypertension, diastolic dysfunction, oxidative stress, inflammation, changes in atrial size, and the use of respiratory drugs for the treatment of COPD are important. Understanding the relationship between COPD and AF is of particular importance because the presence of arrhythmias has a significant impact on mortality, especially in exacerbations of COPD. In the presence of COPD, patients with AF have a more rapid progression of AF, recurrence of AF after catheter ablation, and an increase in mortality from cardiovascular diseases. Treatment of the underlying disease, correction of hypoxia and acid‑base imbalance is the first line therapy for patients with COPD who develop AF. Cardioselective β‑blockers are safe and can be used for COPD. AF ablation is effective and safe and improves the quality of life of these patients.

The high risk of developing adverse drug reactions (ADRs) among elderly and senile patients is caused several reasons. Firstly, the age‑associated changes organs and system cause certain changes in pharmacodynamics and pharmacokinetics of drugs and, as a consequence, atypical ADRs. Secondly, polymorbidity, which is often present in this category of patients, causes the phenomenon of polypharmacy, thereby exacerbating the aspect of drug‑drug interactions – one of the risk factors for the development of ADRs. Finally, low level of knowledge in this area healthcare practitioners causes reason developing of «pharmacological cascades». The active applying of geriatric pharmacology in clinical practices gives the chance do better live the quality of life and the prediction of diseases for elderly and senile patients.
