Authors: Atri Faezeh , Rasaie Vanya , Nikzad Jamnani Sakineh , Mohammadi Saba
Published: January 2023

Background. Zirconia has been used as a reliable core material in dental restorations for years; however, its bonding to resin cement is a matter of challenge. Physical, chemical, and combinations of these techniques have been investigated to boost the properties of zirconia surface bonding. The objective of this work was to evaluate the effect of hydroxyapatite coating as a chemical therapy in combination with physical modifications on the microshear bond strength of the resin cement over zirconia. Methods. In the present research, 60 sintered zirconia blocks (4 × 4 × 4 mm) were randomized into four groups of 15, including Al2O3 particle abrasion (group 1), HA coating (group 2), Al2O3 particle abrasion + HA coating (group 3), and Er, Cr: YSGG laser irradiation + HA coating (group 4). The microshear bond strength was determined by bonding the blocks to the resin cement. Results. The bond strengths (mean ± standard deviation) of modified zirconia surfaces were 16.93 ± 4.94 MPa, 16.14 ± 5.4 MPa, 19.4 ± 5.27 MPa, and 16.21 ± 3.7 MPa in groups 1–4, respectively. Test results of the ANOVA test revealed no significant difference regarding the bond strength values of zirconia surfaces to the resin cement between the studied preparation modalities (

). Conclusion. Observations from the present study showed that HA coating can be as effective as the air-borne particle abrasion technique in improving bond strength to zirconia surfaces. Moreover, sandblasting by an aluminum oxide or Er, Cr: YSGG laser irradiation prior to HA coating of zirconia showed no significant effect on the reinforcement of bond strength values when compared to HA coating alone. The clinic hydroxyapatite coating alone or in combination with physical treatments improves the bond strength of zirconia to resin cement.

Published: January 2023

Introduction: Bone-anchored hearing devices (BAHD) are well-known good solution for single-sided deafness (SSD). Despite power extension of recently introduced BAHD with implanted active transducer, with indications up to 65 dB Hl of bone conduction (BC) threshold on the implanted side, their indications for SSD still remain better than 25 dB on the good ear, with regards to bone conduction thresholds. The aim of this study was to assess the possibility to enlarge BAHD indications for SSD by means of a newly proposed candidacy evaluation protocol, which includes a new software-aided method. Methods: 20 SSD patients (mean age 56 years, 9 females, and 11 males) were divided into two groups: group A (10 patients, BC <25 dB Hl on the hearing side) and group B (10 patients, BC between 25 and 35 dB Hl). Recipients were submitted to bisyllabic words speech audiometry in silence and to authors’ newly proposed IFastSRT50 test by means of software which shift noise intensity of a single word list on the basis of correct recipient recognition responses. A sound speaker for signal (bisyllabic words) and noise (babble) was disposed at 1 m from the deaf side of the patient. An earphone covering only the good ear of the recipient was used in order to perform its air conduction masking with white noise. A BAHD test device was disposed on the mastoid of the deaf side. Both signal and masking intensities were set to 55 dB SPL in order to mask airway conduction on the good ear without masking its bone way interaural conduction from the BAHD tester. Results: With BAHD tester turned off, no recognition was detected. Speech audiometry with BAHD tester turned on revealed mean values of 92% for group A and 89% for group B, with a difference of 3.0% (χ2 = 0.285 and p = 0.5935). As for IFastSRT50 with BAHD tester turned on, mean signal-to-noise ratio value to obtain 50% of recognition was −6.89 for group A and −6, with a difference of 0.89 (t = 1,201 and p = 0.2453). Conclusion: BAHD are confirmed to be a good solution for SSD cases. The absence of statistically significant differences in our two tested groups suggests that newer implanted active transducer device indications should be extended up to 35 dB Hl on the hearing ear. The IFastSRT50 is a reliable and quick method to enhance preoperative candidacy evaluation.
Quando a Cultura é Política: Teatros Negros e Políticas Culturais no final do século XX e início do século XXI
Authors: Terra Terra Johari
Published: January 2023

Neste artigo, evidencio algumas trajetórias dos teatros negros brasileiros, com foco em São Paulo, Rio de Janeiro e Salvador, no período entre a ditadura civil-militar na década de 1970 e a primeira década dos anos 2000, analisando a centralidade da articulação entre cultura e política que possibilitou sua expansão contemporânea. Ao longo desse período, enquanto a reorganização dos movimentos negros pavimentava o caminho para incidir nas políticas do Estado brasileiro e conquistava avanços na Constituição de 1988, os teatros negros passaram por transformações e atuaram nas políticas culturais, conquistando maiores possibilidades materiais, estéticas e técnicas, porém ainda enfrentando os obstáculos persistentes impostos pelo racismo no país. Para realizar esta análise, mergulho na bibliografia pertinente ao tema e na Revista Legítima Defesa, uma publicação desenvolvida pelo grupo paulista de teatro negro Cia. Os Crespos, com o qual dialoguei ao longo de minha pesquisa de mestrado.

The presence of Shiga toxin-producing Escherichia coli (STEC) and resistance to beta-lactams in healthy sheep represents a potential public health risk. This study aimed to characterize STEC isolates in sheep feces for toxin production and resistance to beta lactam antibiotics. In the present study, among the 40 isolates, we found a predominance of subtype Stx1 (22/40), followed by subtype Stx1 + Stx2 (11/40), while the less prevalent group was Stx2 (7/40). Also, we found phenotypical resistance to beta-lactam antibiotics in 50% (20/40) of the strains analyzed, forming two groups, one with resistant isolates and the other with non-resistant isolates. The cytotoxicity of the isolates did not vary among the groups. In addition to having this characteristic, some multiresistant isolates produced significant amounts of toxins. This leads to the conclusion that the mechanisms of antimicrobial resistance via beta lactamases are present in sheep STEC and that the cytotoxicity of those isolates is variable regarding such resistance.
Silenciamentos, invisibilidades e subversões de gênero em A vida invisível de Eurídice Gusmão, de Martha Batalha
Authors: Lebkuchen Jessé Carvalho , Zimmermann Jian Marcel
Published: January 2023

Este trabalho analisa diferentes experiências de gênero no romance A vida invisível de Eurídice Gusmão, de Martha Batalha. Nota-se que a realidade vivida pela protagonista não é a mesma das personagens que ocupam papéis antagônicos ou secundários, existindo vários níveis de invisibilidade de gênero. Nesse sentido, o que pode ser considerado como uma forma de subversão para Eurídice Gusmão é uma ação cotidiana de outras mulheres da narrativa, que sofrem outros tipos de silenciamentos, necessitando também novas formas de resistência.

Authors: Gomes Jodie Elly Silva , Martins Edson Soares
Published: January 2023

Este artigo analisa os aspectos que denotam a complexidade do romance Eu sou umalésbica (1983), de Cassandra Rios, diante de três direcionamentos: os elementos sociais da época emque o romance foi produzido, o confronto de duas consciências e a identificação de pensamentos eações eróticas na linguagem da narradora. Pretendemos abordar como a sociedade brasileira dadécada de 1980 enxergava a mulher e como esse fator influenciou a autora no momento daelaboração do romance, pois há a presença de personagens mulheres que seguem o padrãoheteronormativo ao tempo que há aquelas tidas como transgressoras. Contamos com a teoria deButler (2002), Freud (2014) e Bakhtin (2011) para uma investigação do conteúdo e da linguagem

Authors: Nazareth Eduardo Fernandes
Published: January 2023

Em trabalho de campo para uma pesquisa sobre esportes coletivos, uma série de relatos de um jogador de basquete chamou a atenção. Tratava-se de descrição de suas dificuldades de adaptação ao modo de jogar da nova equipe, algo comum entre jogadores nos esportes coletivos. O presente artigo se debruça sobre o caso dessejogador, explorando várias dimensões de seu relato e mobilizando alguns importantes referenciais teóricos no tratamento da questão. A análise dos relatos nos permitiu melhor compreender a complexidade dos aspectos envolvidos nos processos de construção do corpo atlético, sua relação com o ser jogador, e com o contexto em que isso geralmenteocorre – o da constituição de uma equipe –, revelando ainda a formação da dimensão intercorporal própria do jogar coletivo e da experiência dos mundos dos jogos esportivos coletivos.

Além disso, demonstramos como o histórico de enfrentamento de doenças infecciosas da clínica a equipou para adaptar os serviços preventivos às necessidades dos pacientes durante a pandemia. Nossa parceria acadêmico-comunidade utilizou uma abordagem multidisciplinar, contando com a análise de dados históricos, dados etnográficos e experiência clínica direta. Identifi camos estratégias de prevenção específicas juntamente com áreas de melhoria. Concluímos que a clínica serve como modelo para continuidade de cuidados em ambientes urbanos durante a pandemia.
O conto Assombramento, de Afonso Arinos: o medo, a mente e o horror entre símbolos e sombras
Authors: Pimenta Fernando Januário
Published: January 2023

Propõe-se a análise comentada de elementos diversos, porém interrelacionados, presentes na narrativa do conto “Assombramento” (1898), do escritor brasileiro Afonso Arinos de Melo Franco (1868-1916). São aspectos referentes à naturezado medo e do horror, da perturbação da mente, de símbolos e de superstições, buscando referências nas crenças e nas máximas populares como  documentadas pelo etnógrafo e folclorista brasileiro Luís da Câmara Cascudo (1898-1986), em seus livros Coisas que o povo diz (2009) e Lendas brasileiras (2020).
House of Ashes e as mecânicas de uma narrativa interativa de horror
Authors: Sasse Pedro
Published: January 2023

Nascido do gótico literário, o horror, a partir do século XX, abraçou o cinema como um de seus principais meios. No século XXI, os jogos digitais ganham força como um novo espaço de produção de narrativas de medo, demandando da crítica especializada um esforço de compreensão das novas formas de se produzir horror que dele surgem. Nesse sentido, um gênero específico chama a atenção por se encontrar em posição fronteiriça entre os games e o cinema: os jogos de  narrativa interativa, em que um jogador determina, por suas ações, o desenrolar de uma narrativa majoritariamenteapresentada através de cinemáticas. Tomando como objeto o jogo House of Ashes (2021), da Supermassive Games, propomos, aqui, uma análise crítica das mecânicas utilizadas nesse tipo de jogo, tendo em vista seus obstáculos para a produção dos efeitos estéticos do horror – sobretudo quando comparado ao já consolidado gênero survival horror.
“Fiel até a morte”: uma análise do passado gótico em A sucessora (1934) e Rebecca (1938)
Authors: Santos Ana Paula
Published: January 2023

O presente artigo procura entender a conexão existente entre A sucessora (1934), de Carolina Nabuco, e Rebecca (1938), de Daphne Du Maurier, para além da suspeita de plágio e, assim, estabelecer ambas as obras como pertencentes à tradição literária do Gótico feminino. Para esse fim, serão utilizados como suporte teórico sobre Gótico literário estudos de David Punter (1996) e Júlio França (2016, 2017), e as considerações de Anne Williams (1995) no que diz respeito à vertente feminina do Gótico. No desenvolvimento deste trabalho, será demonstrado como as narrativas de Nabuco e Du Maurier exploram os efeitos do medo provenientes de um passado gótico, personificado na figura fantasmagórica de uma esposa morta, responsável por colocar em xeque a felicidade matrimonial das personagens femininas de ambas as tramas. Ao fazê-lo, essas escritoras utilizam tanto características formais próprias da ficção gótica – o retorno fantasmagórico do passado – quanto temáticas próprias do Gótico feminino – os casamentos fadados ao fracasso.

A flor e a palavra: sobre a linguagem da natureza em Hölderlin e Heidegger
Authors: Fernandes João Evangelista
Published: January 2023

O artigo defende a hipótese de uma linguagem da natureza a partir da interpretação ontológica da poesia de Hölderlin, contrária à interpretação estética feita por Benjamin e acolhida por Adorno. A exegese heideggeriana da φύσις grega, que ele compara à de Hölderlin, será o fio condutor para diferenciar a leitura ontológica da leitura estética e para defender a possibilidade de a natureza falar ao coração do poeta de modo pré-discursivo. O artigo termina com a análise do poema místico de Angelus Silesius, cujo objetivo é reafirmar tal hipótese e não defender uma mística em Heidegger e nem em Hölderlin.
Inversão real e inversão ideal: a crítica da ideologia em A ideologia alemã
Authors: Zanola Gisele
Published: January 2023

Este artigo apresenta o conceito de ideologia em A ideologia alemã, de Marx e Engels, a partir da relação entre a inversão real gerada pela divisão do trabalho e a inversão ideológica, considerando o problema de a ideologia ser caracterizada como a inversão da realidade das relações de produção ao mesmo tempo que a expressão dessas mesmas relações. Por meio da análise do conceito procura-se reavaliar a importância dos manuscritos inacabados de “I. Feuerbach”, tendo em vista que a discussão bibliográfica mais recente atribui ao texto um caráter menor se comparado ao capítulo dedicado a Stirner.

Rupturas e fragmentos: a gênese da obra em prosa de Annette von Droste-Hülshoff
Authors: Nowinska Magdalena
Published: January 2023

Poucas autoras alemãs em geral, e menos ainda autoras alemãs do século XIX, são hoje em dia tão extensivamente pesquisadas e estudadas como Annette von Droste-Hülshoff (1797-1848). Essa recepção intensa, no entanto, é um fenômeno relativamente recente e oculta o contexto da gênese e a história da publicação de seus escritos. Embora Droste-Hülshoff tenha conseguido ainda em vida se estabelecer como autora de obras líricas, o cenário dos seus projetos em prosa é bem diferente: aqui predominam fragmentos, textos não-publicados, projetos abandonados e rejeição por parte da crítica. Este artigo propõe-se a explorar as razões por trás desse cenário, por meio da análise da gênese da obra em prosa de Droste-Hülshoff. Com base em uma discussão das circunstâncias dessa gênese, busca-se identificar alguns fatores que influenciavam a produção literária de mulheres no século XIX na Alemanha.

Reflexões sobre a autoria poética da mulher em "Nada, esta espuma", de Ana Cristina Cesar
Authors: Gueiral Mariana Borda Anderson
Published: January 2023

Em Cenas de Abril (1979), Ana Cristina Cesar surge para inovar o discurso poético produzido por mulheres. A escrita esfíngica da autora contribui para as contemplações do ser mulher em relação ao desejo que envolve a escrita. No poema “Nada, esta espuma”, selecionado para a análise, Ana Cristina Cesar revela uma voz que insiste na “maldade de escrever” ao personificar, pela presença das figuras da deusa e da sereia, o acossamento ou a libertação do fazer poético como forma de expressão: ambivalências que permeiam o discurso da eu-lírico. Dessa forma, o presente artigo analisará os deslocamentos da mulher perante a escrita, de acordo com a obra O riso da medusa (2022), da autora Hélène Cixous. Para analisar os significados das figuras apresentadas no poema de Ana Cristina, como a deusa que “castiga” e a sereia que possui seio livre, esse trabalho abordará as leituras teóricas Um é o outro (1986), de Elisabeth Badinter e “Sereias: sedução e saber” (2020), de Adelia Bezerra de Menezes.
Anni Albers e sua obra: a busca da excelência como processo
Authors: Golia Francine Ferreira de Nardi , Bamonte Joedy Luciana Barros Marins
Published: January 2023

Dentre o que poderia simplesmente ser compreendido como subestimação ao ser colocada na oficina têxtil da Bauhaus, ao invés do ateliê de pintura, a atuação de Anni Albers na icônica escola alemã demonstrou a excelência em criar a partir dos desafios e superar-se constantemente. Assim, o presente texto foi desenvolvido para se compreender melhor a trajetória da artista, bem como as metodologias de ensino e as práticas dos projetos desenvolvidos por ela. O estudo de seus próprios registros enquanto documentos de processo, bem como de textos de Otto & Rössler, Ambler, e de Salles, constituem os aportes teóricos para o trabalho aqui apresentado, de modo a compreender sua trajetória e pensamento, tão relevantes para a arte e o design na contemporaneidade.
Nos rastros do arquivo: um olhar possível sobre o Fundo Hilda Hilst
Authors: Shcolnik Fernanda
Published: January 2023

Neste trabalho, apresentamos um olhar possível sobre a formação do Fundo Hilda Hilst, arquivo da escritora, localizado no Centro de Documentação Cultural Alexandre Eulálio (CEDAE/UNICAMP). Partindo do pensamento de Serge Margel sobre os arquivos e do conceito de “arquivamento do eu”, de Philippe Artières (1998), tecemos uma breve reflexão sobre o processo de construção do arquivo de Hilda Hilst e seus sentidos possíveis. Materiais como fragmentos de cartas e diários evidenciam aspectos do processo de criação literária da escritora e fornecem elementos para a análise de seus projetos artísticos e sua relação com os espaços do circuito literário, como editoras e outros meios de divulgação de sua obra. Por outro lado, o resgate histórico da venda de materiais do arquivo pela própria escritora para a UNICAMP na década de 1990 constitui aspecto crucial na tentativa de mapear a construção do acervo pela autora, pois permite pensar intencionalidades de Hilda Hilst, apontando para a compreensão do arquivo como parte de sua obra e como estratégia de consagração.
Cause‐Specific Mortality of Patients With Atrial Septal Defect and Up to 50 Years of Follow‐Up
Authors: Muroke Valtteri , Jalanko Mikko , Haukka Jari , Sinisalo Juha
Published: January 2023

Background

This study aimed to evaluate the long‐term mortality and cause‐specific mortality of patients with atrial septal defect (ASD) in a nationwide cohort.

Methods and Results

All patients diagnosed with simple ASD in the hospital discharge registry from 1969 to 2019 were included in the study. Complex congenital defects were excluded. Each subject was matched with 5 controls according to sex, age, and municipality at the index time. Adjusted mortality risk ratios (MRRs) were calculated using Poisson regression models. The median follow‐up time was 11.1 years. Patients with ASD had higher overall mortality during follow‐up, with an adjusted MRR of 1.72 (95% CI, 1.61–1.83). Patients with closed ASDs also had higher total mortality (MRR, 1.29 [95% CI, 1.10–1.51]). However, no difference in mortality was detected if the defect was closed before the age of 30 (MRR, 1.58 [95% CI, 0.90–2.77]), and transcatheter closed defects had lower mortality than the control cohort (MRR, 0.65 [95% CI, 0.42–0.99]). Patients with ASD had significantly more deaths due to congenital malformations (MRR, 54.61 [95% CI, 34.03–87.64]), other diseases of the circulatory system (MRR, 2.90 [95% CI, 2.42–3.49]), stroke (MRR, 1.89 [95% CI, 1.52–2.33]), diseases of the endocrine (MRR, 1.88 [95% CI, 1.10–3.22]) and respiratory system (MRR, 1.71 [95% CI, 1.19–2.45]), ischemic heart disease (MRR, 1.62 [95% CI, 1.41–1.86]), and accidents (MRR, 1.41 [95% CI, 1.05–1.89]).

Conclusions

Patients with ASD had higher overall mortality compared with a matched general population cohort. Increased cause‐specific mortality was seen in congenital malformations, stroke, and heart diseases.

Behavioral studies revealed that time perception is affected by the presence of a reward. Both the experience of time and the reward processing were shown to be distorted in major depressive disorder (MDD). We aimed to investigate how neural correlates of time perception and reward anticipation interact in patients with MDD. Participants (17 healthy, seven MDD) performed a time perception task during fMRI scanning that requires estimating the speed of a moving rectangle which was briefly occluded. In the control condition, participants attended to the change in color tone of the rectangle. Half of the runs were rewarded with a monetary payment per correctly done trial to evaluate the effect of a reward. The fMRI data were acquired with a 3T scanner and analyzed with repeated-measures analysis of variance (ANOVA) using SPM12. The activations related to the integration of time with reward were different between both groups in the supplementary motor area, intraparietal sulcus, thalamus, frontal eye field and caudate nucleus. Increased coupling between supplementary motor area and caudate/putamen region during timing was found in MDD patients more than in controls. Overall, our findings suggest that functional differences related to the interaction of time perception with reward anticipation in MDD occur via dysfunction of the cortico-striatal-thalamic network.

Estimating the Significance of the Added Skill from Initializations: The Case of Decadal Predictions
Authors: Christiansen Bo , Yang Shuting , Matte Dominic
Published: January 2023

A considerable part of the skill in decadal forecasts often comes from the forcings, which are present in both initialized and uninitialized model experiments. This makes the added value from initialization difficult to assess. We investigate statistical tests to quantify if initialized forecasts provide skill over the uninitialized experiments. We consider three correlation-based statistics previously used in the literature. The distributions of these statistics under the null hypothesis that initialization has no added values are calculated by a surrogate data method. We present some simple examples and study the statistical power of the tests. We find that there can be large differences in both the values and power for the different statistics. In general, the simple statistic defined as the difference between the skill of the initialized and uninitialized experiments behaves best. However, for all statistics the risk of rejecting the true null hypothesis is too high compared to the nominal value. We compare the three tests on initialized decadal predictions (hindcasts) of near-surface temperature performed with a climate model and find evidence for a significant effect of initializations for small lead times. In contrast, we find only little evidence for a significant effect of initializations for lead times longer than 3 years when the experience from the simple experiments is included in the estimation.
Webs of oppression: An intersectional analysis of inequalities facing women activists in Palestine
Authors: Nazzal Amal , Stringfellow Lindsay , Maclean Mairi
Published: January 2023

How can we understand the multiple, intersecting webs of oppression that Palestinian women activists face in their everyday organizing? With a long tradition of counter-hegemonic organizing, the Palestinian context presents opportunities and challenges for women pursuing activist causes in the public domain. Adopting an intersectionality framework, we uncover how gender, class and settler-colonized domination interact, engendering dynamics of oppression differentiated by activists’ social positions. Activists’ stories captured at interview reveal they were not victims across all categories of difference, experiencing forms of relative privilege, characterized as safeguarded, secured and sheltered. We connect relative privilege to the patchwork nature of Palestinian institutions, whereby women’s agency intermingles with a patchwork of historically constituted structures and conditions. Our fine-grained study contributes to literature on feminist and activist organizing and to theorizations of intersectionality by identifying forms of relative oppression and privilege as women actively resist hegemonic gendered structures in Palestine.
Doing inclusion as counter-conduct: Navigating the paradoxes of organizing for refugee and migrant inclusion
Authors: Kangas-Müller Laura , Eräranta Kirsi , Moisander Johanna
Published: January 2023

Are organizational projects for refugee and migrant inclusion always trapped with the logic of exclusion and inequality that they seek to dismantle? Existing literature on critical diversity and inclusion studies has demonstrated how the “doing” of inclusion in organizations tends to come with paradoxical effects: well-intended efforts to include migrants and refugees construct them as vulnerable, non-autonomous subjects who need help, within a hierarchical order that is taken for granted. Based on ethnographic fieldwork, this article explores how three civil society organizations (CSOs) navigate these paradoxical effects and the unduly constraining power relations involved through practices that we theorize as counter-conduct against the pastoral government of a national refugee and migrant integration regime. The analysis identifies three practices of counter-conduct through which organizations “do inclusion differently”: contesting constraining categorizations, problematizing hierarchical power relations, and questioning the assimilationist goals and principles of the integration regime. We argue that through continuous critique and renegotiation of the ways in which boundaries of inclusion/exclusion are drawn within the integration regime, organizations work toward conditions in which power relations remain fluid and allow for strategies to alter them.
Therapeutic work with clients living in poverty
Authors: Ballo Elvera , Tribe Rachel
Published: January 2023

Background:

Financial inequalities appear to be increasing and poverty is becoming ubiquitous. Poverty affects mental health but its impact on mental health and wellbeing is rarely highlighted within health research.

Aims:

The Covid-19 pandemic, the Ukrainian invasion and other international and national events have led to a cost-of-living crisis for many people. This is likely to lead to an increase in related referrals and therefore active consideration of the relevant issues relating to poverty appears vital. This paper reports a study which sought to understand how therapists experienced their work with clients who self-refer due to living in poverty.

Method:

Eight therapists participated in semi-structured interviews analysed using Interpretative Phenomenological Analysis (IPA).

Results:

Three superordinate themes were elicited: firstly ‘Resilience in the struggle to engage with therapeutic work’, secondly ‘Struggling to promote social activism’ and thirdly, ‘Navigating multiple challenges and barriers’. Each superordinate theme contains two or three sub themes.

Conclusions:

Issues of structural inequality (including but not limited to poverty) impact significantly on people’s lives but are often ignored or minimised in therapeutic work. It is important that therapists are aware of poverty and take this into account when working with clients.
Friction force estimation in pneumatic cylinders by full automation of experimental procedures
Authors: Dağdelen Mustafa , Sarıgeçili Mehmet İlteriş
Published: January 2023

The effective utilization of pneumatic cylinders in precise control applications requires the correct determination of unpredictable, variable, and non-linear friction resistance characteristics. Even though the friction characteristics depend on many structural and operating variables, the existing expensive experimental methodologies are prone to error, time-consuming, and have excessive computational burden. In this study, the full automation of friction force estimation processes has been designed and implemented with MATLAB/Stateflow including the execution of all experimental steps, processing of signals, extraction and classification of data, and estimation of parameters. An operational graphical user interface has been developed for entering the required input values of the experimental procedures, connecting to testing equipment, carrying out experiments, and presenting obtained model parameters. The friction force parameters of three pneumatic cylinders, two of which were identical, have been determined both with the automated method and the manual method. The automated method has produced better results compared to the manual method while reducing the total estimation duration drastically. The pressure tracking performance tests conducted to verify the friction model parameters have exhibited better tracking performances with the automated method results.

Authors: Stojanović Milan , Vračar Ljubomir , Živaljevic Dragana , Neden Dimitriu Ilija
Published: January 2023

Designing of the vehicle magnetic signature generator is presented in this paper. The basic concept used in designing is distortion of the Earth’s magnetic field that occurs in the presence of ferromagnetic materials. The experimental setup for measuring the magnetic field distortion caused by a vehicle is presented, and based on the obtained values of the magnetic field, input data for signature generator are obtained. The magnetic signature generator consists of a solenoid with a copper wire wound on the bobbin made by the three-dimensional (3D) printer, and an arbitrary function generator RIGOL DG1022Z. Determination of the solenoid parameters and a voltage level of a generator are described thoroughly. In order to demonstrate performances of the generator, magnetic signatures of four different vehicles are generated by proposed design and compared with measured ones by Pearson’s correlation coefficient, indicating a greater correlation than 0.993.

Authors: K Muralidharan , Vaira Vignesh R , Govindaraju M
Published: January 2023

Copper-based brake pad materials with various fractions of praseodymium oxide and yttrium oxide are fabricated through the powder metallurgy processing technique. The influence of praseodymium oxide and yttrium oxide on the microstructure, microhardness, and tribological characteristics of the fabricated specimens are analyzed. The specimen with desired density, high hardness, wear resistance, and optimal friction coefficient is fabricated with gradient layers (pure copper at the brake pad – brake caliper interface and composite at the brake pad – brake disc interface). The result suggested that as the load gradually increases, the wear rate also increases. The surface morphology, elemental composition, and phase composition of the fabricated specimen and worn surface were characterized using advanced instrumental characterization.
Diffracting the Global: Exploring the Implementation of WHO’s COVID-19 Protocols in Sub-Saharan Africa
Authors: Sebeelo Tebogo
Published: January 2023

The coronavirus disease 2019 (COVID-19) has impacted the world in unprecedented ways. To deal with the virus, countries across the world implemented COVID-19-related protocols that include social distancing, washing hands, wearing masks and restricting movements of people. While the literature on the impact of COVID-19 is emerging, it is still relatively unknown how the virus affected countries in sub-Saharan Africa. This article explores the impact of COVID-19 protocols in sub-Saharan Africa. The article broadly argues that an all-assuming and globalised approach of COVID-19 protocols is antithetical to the sub-Saharan African continent with its vast territories and unique populations. The article highlights that the African continent that houses the world’s poorest populations cannot be adequately served by COVID-19 protocols in similar ways to Western countries. It is further suggested that COVID-19 protocols that reify universalism may need to be adapted and domesticated to fit the African context. The article provides critical insights into the experience of COVID-19 protocols that has several policy implications for future pandemics and disease outbreaks in the African continent.

Parental burnout (PB) is a chronic stress-related condition resulting from long-lasting exposure to overwhelming parenting stress. Previous studies showing the seriousness of this condition stressed the urgent need to provide researchers and practitioners with effective assessment tools. Validated PB measures are the Parental Burnout Inventory (PBI) and the Parental Burnout Assessment (PBA). The good psychometric properties of these instruments have been replicated across different samples and countries, but thresholds for identifying impairing PB levels (i.e., cutoff scores) have not yet been established. The present study aims to fill this gap by adopting a multi-informant and multimethod approach to a sample of 192 burned-out and control parents. PBI and PBA cutoffs were derived from the combination of several PB indicators, based on a preregistered analysis strategy. Results identified a score of 74.6 (95% confidence interval (CI) = [69.48–79.68]) for the PBI and 86.3 (95% CI = [79.49–93.03]) for the PBA as indicators of the most severe PB levels.

Published: January 2023

Background

Surgical smoke can be a hazard because e it contains toxic gases with carcinogenic effects that may threaten health. This study aims to determine the effect of surgical smoke containing toxic chemicals on indoor air quality and examine employees’ physical symptoms in the operating room.

Method

The study was conducted in the operating room between June 2020 and July 2020. In the study, 45 air samples were taken before, during, and after surgery using the active sampling method. Nineteen employees working in the operating room were asked about their physical complaints and their throat cultures were taken before and after surgery. These results were compared with those of the employees working in internal units.

Results

The Total Volatile Organic Compounds value at the time of surgery was significantly higher ( p ≤ 0.05). Benzene concentrations remained constantly high ( p ≤ 0.05) throughout the surgery, exceeding the limit values. Other VOCs (Volatile Organic Compounds) were significantly higher during surgery and remained below the limit values ( p ≤ 0.05). When compared in terms of open and laparoscopic surgery, no difference between VOC concentrations was observed ( p ≤ 0.05). The physical symptoms of the surgical team increased during the operation, and they experienced more complaints of tearing, burning in the eyes, hair odor, nausea, and cough than those working in the internal units (e.g., internal medicine, dermatology; ( p ≤ 0.05).

Conclusions

Surgical smoke was an important contaminant for indoor air quality in the operating room.
The Financial Risks of Unpaid Caregiving During the COVID-19 Pandemic: Results From a Self-reported Survey in a Canadian Jurisdiction

Published: January 2023

As health service delivery shifts from institutions to the home, greater care responsibilities are being imposed on unpaid caregivers. However, gaps remain concerning how these responsibilities are contributing to caregivers’ financial risk. This study describes results from an online survey conducted in late-2020 in Ontario, Canada, about the financial risks of unpaid, homebased caregiving throughout the first year of the COVID-19 pandemic. Among 190 caregivers, salient findings include difficulties paying for care expenses after the pandemic was declared than before ( P = .002); more caregivers retiring or becoming unemployed during the pandemic than before ( P = .013); and a significant relationship between paying out-of-pocket for a home care worker and experiencing a decrease in the availability of such support during the pandemic ( P = .029). Overall, the financial stressors of caregiving during the pandemic contributed negatively to caregivers’ mental health, with 64.2% noting could be partly offset by greater government and employment-based assistance in managing care expenses and productivity losses. Findings from this study will better inform policies that aim to protect unpaid caregivers from financial risk in pandemic recovery efforts and beyond. Results may also be useful in other welfare states where unpaid caregivers provide the majority of home care services.
Spanish Twitch streamers: Personal influence in a broadcast model akin to television
Authors: Sixto-García José , Losada-Fernández Diego
Published: January 2023

Following the migration of influencers from YouTube to Twitch and the boom in popularity experienced by the latter social network, this paper explores if brands are capitalizing on the influence capacity of streamers or if streamers might be getting money from their own content. In order to investigate this, it was necessary to perform a quantitative analysis on the publication schedules and broadcast formats used by streamers. This facilitated the simultaneous identification of another main finding: Spanish streamers are using a broadcast model on Twitch that resembles that of open linear television. Although they only broadcast content related to videogames, trends towards other types of audiovisual content have already been identified. Moreover, it has been found that influential streamers prioritize Twitch over other social networks even though feedback flows have been detected, especially from Twitch to other platforms. This work represents a contribution to knowledge in terms of understanding Twitch and understanding platforms and influencers. It is important to determine whether these new forms of broadcasting and interaction could be considered a hybrid model between linear television and social media streaming.
Pharmacokinetics of zanamivir in critically ill patients undergoing continuous venovenous hemofiltration
Authors: Wieringa André , ter Horst Peter GJ , Wagenvoort GertJan HJ , Koch Birgit CP , Haringman Jasper J
Published: January 2023

Background

Limited data exist for dosing of zanamivir in the setting of CVVH in the intensive care unit (ICU). Our objective is to report the pharmacokinetics and sieving coefficient (Sv) of zanamivir in patients receiving continuous venovenous hemofiltration (CVVH).

Methods

In this prospective observational study, patients of ≥18 years admitted to the ICU with a life-threatening Influenza A or B infection, treated with zanamivir i.v. undergoing CVVH were included. Patients received a zanamivir loading dose of 600 mg i.v., 12 h later followed by maintenance dosages two times daily according to the treating physician. Per patient, nine CFT plasma and nine ultrafiltrate samples were drawn on day 2 of treatment and analysed with a validated HPLC-MS/MS method.

Results

Four patients were included in the study. The zanamivir elimination half-life was prolonged with 5.6–9.9 h, compared to patients with normal renal function. A Sv of approximately 1.0 was identified, with unrestricted transport of zanamivir to the ultrafiltrate.

Conclusions

Zanamivir is well cleared by CVVH. In absence of the possibility for therapeutic drug monitoring, the ultrafiltration rate seems as a good surrogate parameter to estimate the CLCVVH and may help guide the dosing of zanamivir.
