Alfredo Veiga-Neto, arqueogenealogia intempestiva de um pensamento
Authors: Passetti Edson , Conde Heliana
Published: May 2023

Ele toca piano, é-foi biólogo, só encontra palavras fortes e sutis para seus parceiros. É um tradutor cuidadosíssimo, um arquivista foucaultiano, um ensaísta equilibrado, o generoso companheiro de convivências amplas e nas contingências urgentes.Isso tudo, fomos constatando pouco a pouco, desde a generosidade, evidenciada no primeiro encontro. Curioso é lembrar o espanto (e a alegria correlata) que acompanhou, para um(a) de nós, Heliana, a circunstância já longínqua de se deparar, em uma livraria carioca, com a coletânea O Sujeito da Educação (Silva, 1994): estariam pensadores ligados à Teoria Crítica, marxistas frankfurteanos, “devindo” outra coisa? – o subtítulo do volume (Estudos foucaultianos) não dava muita margem a que a pergunta perdurasse. Notadamente porque, no ano seguinte, Crítica pós-estruturalista em educação, já então organizada por Alfredo Veiga-Neto (1995a), confirmaria as diferenças que se afirmavam por intensidades, mais do que por cronologias ou rotulações político-acadêmicas. Do léxico galego da língua portuguesa, veiga, substantivo feminino, é “planície ou vale suave e fértil; terreno plano, bom, de lavradio; grande chaira de terreno comunal; leira destinada à sementeira de milho, batatas, etc.; lavradio onde vários vizinhos têm uma parcela; terreno sempre húmido, normalmente com outono; estar na veiga: o mesmo que estar na horta, não tomar consciência ou perceber o que sucede; veiga com fame: veiga ou terreno pouco estercada; veiga da porta: veiga que está junto à casa[1]. “Regionalismo: terra de cultivo de centeio ou milho serôdio”[2]. Pré-romana: baika, terreno inundado, chã, campina, várzea. É a floração das ameixeiras, anunciando a primavera japonesa (um dos locais mais renomados para se ver a baika fica a uma hora e meia de trem de Tóquio, na província de Ibaraki)[3]. Baika é também uma prática musical zen-budista[4]. Seria uma aeronave a jato a ser construída no Japão durante a II Guerra Mundial, jamais  produzida[5]. Veiga-Neto, Alfredo-Alfie, é da beleza, da paisagem, da terra, da música, do que é fértil e alimenta[6].[1] https://www.estraviz.org/veiga[2] https://www.infopedia.pt/dicionarios/lingua-portuguesa/veiga[3] https://www.japanhousesp.com.br/artigo/baika-floracao-das-ameixeiras/[4] https://aguasdacompaixao.wordpress.com/atividades/baika-a-pratica-de-musica-zen-budista/[5] https://pt.wikipedia.org/wiki/Kawanishi_Baika[6] Alfie, que não o da canção de Burt Bacharach https://www.letras.mus.br/burt-bacharach/261594/ e muito menos o de Lily Allen https://www.vagalume.com.br/lily-allen/alfie-traducao.html
“VENEZOLANOS EN DOURADOS MS”: UM ESTUDO NETNOGRÁFICO DE COMUNIDADES IMIGRANTES NAS REDES SOCIAIS DIGITAIS
Authors: De Faria Guélmer Júnior Almeida
Published: May 2023

As migrações Sul-Sul evidenciadas no início do século XXI configuram-se como uma expressão dos fluxos migratórios globais. Este artigo discute as sociabilidades migrantes em redes sociais digitais capturadas em uma sociedade global informacional. O objetivo foi de analisar a aplicação do método netnográfico em uma comunidade do Facebook denominada de “Venezolanos en Dourados MS”. Através da netnografia, procurou-se codificar alguns comportamentos, estratégias, situações da comunidade que se configuram neste ambiente online, assim como do fluxo de informações, através da observação e das análises temáticas. Os resultados evidenciam que, essa transposição das relações sociais face a face para o ambiente “entre-telas” favorece a aproximação entre grupos e pessoas. Os imigrantes venezuelano/a/s enxergaram nessas mediações tecnológicas um espaço de desenvolvimento criativo para minimizar as consequências vorazes para quem é marginalizado, e assim, diminuir as lacunas das dificuldades de inserção e acolhimento no país de destino.

A dimensão investigativa na formação em Serviço Social a partir das Diretrizes Curriculares de 1996
Authors: Maroneze Luciane Francielli Zorzetti , Fortuna Sandra Lourenço de Andrade
Published: May 2023

O presente artigo tem por objetivo apreender a dimensão investigativa na formação acadêmico- profissional de assistentes sociais a partir da lógica curricular proposta pelas Diretrizes Curriculares da ABEPSS de 1996. Defende-se a tese de que esta lógica, ancorada no método materialista histórico-dialético, tem na dimensão investigativa uma condição intrínseca na junção entre formação e realidade social. Cabe destacar que as reflexões e análises aqui desenvolvidas são resultado de revisão teórico-bibliográfica de autores do Serviço Social, que discutem a temática em questão aportados na teoria social marxista. Os resultados apontam que captar o lugar que a investigação ocupa na formação é apreender os fundamentos do Serviço Social como unidade, sabendo que cada componente curricular, a partir de suas particularidades na totalidade dos conteúdos, deve pensar em como formar esse perfil investigativo na direção social do projeto profissional.Palavras-chave: Fundamentos do Serviço Social; Diretrizes Curriculares da ABEPSS; Dimensão Investigativa
Gestão e serviço social: desafios para a formação profissional
Authors: Benevides Geis De Oliveira , Lima Maria José de Oliveira
Published: May 2023

O artigo traz reflexões sobre  a gestão na formação profissional do/a assistente social, a partir das Diretrizes Curriculares da ABEPSS de 1996. As considerações apresentadas são resultado de pesquisa bibliográfica, documental e de campo. A motivação para o estudo partiu do pressuposto de que muitos profissionais apresentam resistência em reconhecer a gestão no âmbito do trabalho profissional e, isto se deve à compreensão sobre a gestão apreendidos no processo de formação profissional. Essa investigação conseguiu abordar os determinantes dessa problemática, apontando argumentos a partir da realidade concreta de discentes e docentes, participantes da pesquisa. As análises permitiram entender que para garantir a apreensão da gestão no trabalho do/a assistente social, os conteúdos da disciplina precisam abordar as diferentes perspectivas de gestão, permitindo a construção de mediações que possibilitem apropriar-se da gestão na perspectiva democrática e emancipadora, condizente com os princípios expressos no Projeto Ético- Político do Serviço Social.Palavras chave: Gestão; Serviço Social; Formação Profissional; Gestão democrática e emancipadora.

Inflammatory markers in patients with hypertension
Authors: Yihui Chen , Yanfeng Gong
Published: May 2023

Hypertension is a chronic disease with high levels of morbidity and disability. Elevated blood pressure can lead to many complications and is the main risk factor for stroke, heart failure and nephropathy. Factors associated with hypertension and inflammatory response differ from those associated with vascular inflammation. The immune system plays a vital role in the pathophysiology of hypertension. Inflammation is particularly relevant in the progression of cardiovascular diseases, which has led to extensive research on inflammatory markers and indicators.
Subacute Bacterial Infection Mimicking a Slipped Capital Femoral Epiphysis in an Obese Adolescent Male – A Case Report and Review of Literature
Authors: Modi Nihar , Dave Harshit , Gandbhir Viraj , Keny Swapnil , Mishra Shaswat , Kolur Shivaprasad
Published: May 2023

Introduction: Atypical and subacute presentations of pediatric bacterial septic arthritis are difficult to diagnose due to lack of systemic manifestations and inadequate laboratory data. Furthermore, they may mimic certain well-documented pediatric disorders to confound the diagnosis and management. Case Report: The authors present a case of an adolescent obese male with features suggestive of a slipped capital femoral epiphysis (SCFE). Further investigations revealed bacterial septic arthritis which may have contributed to the slip. He was treated with an initial debridement followed by a definitive pelvic support osteotomy (PSO) with a compensatory distal femoral varus osteotomy. At 12 months, he had a satisfactory clinical and radiological outcome. Conclusion: Clinicians should have a high degree of suspicion for infection in patients presenting with atypical clinical or radiological signs of SCFE. A thorough investigation in such cases is a must, to aid in correct management. PSO is an effective salvage procedure in adolescents with septic hip sequelae.

Management and Outcome of Jeffrey Type 2 Fractures in Paediatric Patients: A Case Series and Review of Literature
Authors: Tupe Rishikesh , Desai Sameer , Tomer Divya , Patil Nilesh
Published: May 2023

Introduction: Fractures of the radial neck are very uncommon in children, accounting for 5–8.5% of all fractures around the elbow in children, and are sometimes found with dislocation of the elbow joint. Jeffery carefully studied and classified these types of radial neck fractures with displaced radial head into several types. Very few cases with Jeffrey fractures are reported in the literature, and most cases were treated by surgery. Only one case of successful closed reduction and cast and two cases of closed reduction and percutaneous pinning have been reported. Case Report: We report two cases of Jeffery Type 2 fractures treated by an open reduction in an 11-year-old and a 13-year-old boy. We describe the difficulties faced in the reduction of the fracture and the complications that occurred in the patients. Conclusion: Jeffery Type 2 fracture is an uncommon and difficult-to-treat injury with the possible complication of the radial head being turned upside down if treated conservatively. Therefore, prompt recognition and careful reduction are essential in this type of injury. Keywords: Jeffery fracture, elbow dislocation, radial neck fracture, pediatric elbow.
Combined Posterior and Convergent Elbow Dislocation in Adult: A Rare Case Report
Authors: Mane Akash Nagnath , Sourav Neel Kamal , Panchnadikar Vijay , Bhandari Abhijit , Venkatakrishna Karthic
Published: May 2023

Introduction: Elbow dislocations are commonly encountered by orthopedic surgeons all over. Management is straightforward and the result is generally satisfactory. However, in a small subset, associated injuries like convergent or divergent dislocations at superior radioulnar joints are present. These associated injuries are often missed initially leading to their delayed treatment and suboptimal elbow function. We report one such rare case of Convergent dislocation at the elbow. Although reported from other parts of the world till date, there has been none reported from India. It is extremely rare in adults. Twenty-three cases in children and only two in adults stand reported so far in world literature. Thus, our reporting it could be the first report of convergent dislocation at the elbow from India. To the best of our knowledge, it is only the third reported adult case in world literature. Case Report: We describe a 68-year-old male visiting a local hospital with a history of fall from a two-wheeler. An initial radiograph revealed an obvious posterior dislocation of the elbow. Closed reduction was performed, and posterior above elbow slab was given. Patient presented to us 10 days later with persistent pain. Evaluation with radiographs confirmed reduction of ulno-humeral joint but translocation of the radius and ulna which is combined posterior and convergent elbow dislocation. Conclusion: Combined posterior and convergent elbow dislocation is a rare scenario. The rarity of these associated injuries is the reason for lack of awareness. We suggest careful scrutiny of pre-reduction anteroposterior radiographic view or 3D CT in suspected cases as well as X-ray/Carm anteroposterior view in extended position of elbow on the operation table immediately after reduction before slab application in every case of elbow dislocation. Significant difficulty was encountered in open reduction in our case. This could be attributed to buttonholing of the radial head through insertion of brachialis fibers. The reporting of this surgical difficulty is important because it will help the surgeon know it beforehand and the awareness would make the surgeon take appropriate measures well in time. Keywords: Convergent elbow dislocation, superior radioulnar joint, buttonholing.
Subchondral fatigue fracture of the femoral head with acetabular dysplasia treated by transposition osteotomy of the acetabulum: a case report
Authors: Miyake Yoshiaki , Mitani Shigeru
Published: May 2023

Introduction: Subchondral insufficiency fracture of the femoral head commonly occurs in older women with osteoporosis. However, subchondral fatigue fracture of the subchondral femoral head is rare. We present a rare case of fatigue fracture of the subchondral femoral head with acetabular dysplasia. Case Report: The patient was a 16-year-old male, height 180 cm, weight 112 kg, and body mass index 34.6 kg/m2. Continuous right hip pain appeared after club activity of table tennis a month before admission to our department. Pain was observed on deep flexion of the right hip joint. The FADIR test was positive. X-ray images showed a depressed deformity of the right femoral head loading area. In addition, the center-edge angle was 10° on the right and 21° on the left, tear drop distance was 12 mm on the right and 8 mm on the left, and bilateral acetabular dysplasia was noted. In magnetic resonance imaging, the T1-weighted image shows low-intensity signal and the T2-weighted image shows high-intensity signal, indicating a fatigue fracture of the femoral head with subchondral depression. Thus, transposition osteotomy of the acetabulum was performed in this case. Postoperatively, the depression portion showed gradual remodeling, and the patient returned to sports after 6 months. Because this patient was highly obese with acetabular dysplasia, a large shear force was applied to the loading portion of the femoral head relative to the acetabular rim. The femoral head was repeatedly forced, resulting in a fatigue fracture. We believe that the stress applied to the depressed portion was dispersed by the transposition osteotomy of the acetabulum, resulting in remodeling. Conclusion: This is the first report of the transposition osteotomy of the acetabulum for a subchondral fatigue fracture of the femoral head with acetabular dysplasia. Thus, this may serve as a reference in the management of such rare occurrences and pave the way for further understanding of this condition. Keywords: Femoral head fracture, acetabular dysplasia, transposition osteotomy of the acetabulum
Chronic Lateral Ankle Instability with Os Subfibulare in a Child Treated with Modified Broström/Gould Surgical Technique – A Case Report
Authors: Grade Dorothea , Cip Johannes , Lengnick Harald
Published: May 2023

Introduction: Patients with lateral instability of the ankle have a much higher prevalence of an os subfibulare compared with the general population. In children and adolescents with known os subfibulare and chronic instability of the ankle, surgical resection of the os subfibulare and the Broström/Gould procedure to reattach the ATFL to the fibula has been described if conservative therapy fails. Case Report: Our case is about a 10-year-old girl with chronic instability of the ankle and a symptomatic os subfibulare, with additional cystic and edematous changes in the distal fibula in the MRI. Due to the reduced bone density, we assumed a higher risk of anchor pullout with the normal refixation at the distal fibula. Therefore, the surgical technique according to Broström/Gould was modified and the ATFL was refixed on the talar side. Conclusion: In cases of symptomatic os subfibulare with clinical instability of the ankle, a Broström/Gould operation and resection of the os subfibulare is recommended after failure of conservative therapy. Our case showed that a very satisfying post-operative result can be achieved with a modification of the Broström/Gould operation, with reattachment of the ATFL to the talus instead of the fibula. Keywords: Instability of the ankle, os subfibulare, Broström/Gould technique, ATFL.

Males have finite resources to spend on reproduction. Thus, males rely on a ‘time investment strategy’ to maximize their reproductive success. For example, maleDrosophila melanogasterextends their mating duration when surrounded by conditions enriched with rivals. Here we report a different form of behavioral plasticity whereby male fruit flies exhibit a shortened duration of mating when they are sexually experienced; we refer to this plasticity as ‘shorter-mating-duration (SMD)’. SMD is a plastic behavior and requires sexually dimorphic taste neurons. We identified several neurons in the male foreleg and midleg that express specific sugar and pheromone receptors. Using a cost-benefit model and behavioral experiments, we further show that SMD behavior exhibits adaptive behavioral plasticity in male flies. Thus, our study delineates the molecular and cellular basis of the sensory inputs required for SMD; this represents a plastic interval timing behavior that could serve as a model system to study how multisensory inputs converge to modify interval timing behavior for improved adaptation.
Rapid screening of sixty potato cultivars for starch profiles to address a consumer glycemic dilemma
Authors: Rivas Rocio , Dratz Edward , Wagner Thomas , Secor Gary , Leckband Amanda , Sands David C.
Published: May 2023

Potatoes are a dietary staple consumed by a significant portion of the world, providing valuable carbohydrates and vitamins. However, most commercially produced potatoes have a high content of highly branched amylopectin starch, which generally results in a high glycemic index (GI). Consumption of foods with high levels of amylopectin elicit a rapid spike in blood glucose levels, which is undesirable for individuals who are pre-diabetic, diabetic, or obese. Some cultivars of potatoes with lower amylopectin levels have previously been identified and are commercially available in niche markets in some countries, but they are relatively unavailable in the United States and Latin America. The high glycemic index of widely available potatoes presents a problematic “consumer’s dilemma” for individuals and families that may not be able to afford a better-balanced, more favorable diet. Some native communities in the Andes (Bolivia, Chile, and Peru) reportedly embrace a tradition of providing low glycemic tubers to people with obesity or diabetes to help people mitigate what is now understood as the negative effects of high blood sugar and obesity. These cultivars are not widely available on a global market. This study examines 60 potato cultivars to identify potatoes with low amylopectin. Three independent analyses of potato starch were used: microscopic examination of granule structure, water absorption, and spectrophotometric analysis of iodine complexes to identify potato cultivars with low amylopectin Differences among cultivars tested were detected by all three types of analyses. The most promising cultivars are Huckleberry Gold, Muru, Multa, Green Mountain, and an October Blue x Colorado Rose cross. Further work is necessary to document the ability of these low amylopectin cultivars to reduce blood glucose spike levels in human subjects.
Toward improvement of knowledge of financial conflicts of interest in a large medical school in France
Authors: Alexandra J. F. , Roux D. , Maisonneuve H. , Chousterman B. , Ruszniewski P. , Dreyfuss D.
Published: May 2023

Introduction

Conflict of interests (COIs) adversely affect the integrity of science and public health. The role of medical schools in the teaching and management of COIs has been highlighted by the publication of an annual evaluation of American medical schools based on their COIs policies by the American Medical Student Association (AMSA). A deontological charter was adopted by French medical schools in 2018 but its impact on COI comprehension by students and its effects on COI prevention were not evaluated.

Methods

A 10-item direct survey was conducted among about 1000 students in Paris-Cité University in order to investigate the respect of the charter regarding COIs both in the medical school and in affiliated teaching hospitals.

Results

Cumulative results show a satisfying respect of prevention policies regarding COIs in the medical school and hospitals despite the fact that the existence of the charter and its major aspects were insufficiently known. Disclosure of COIs by teachers was insufficient.

Conclusion

This first direct study among students shows better results than expected according to current non-academic surveys. Moreover, this study demonstrates the feasibility of this kind of survey whose repetition should be an appropriate tool to improve the implementation of the charter within medical schools and teaching hospitals, in particular mandatory disclosure of COIs by teachers.

People are curious, suspicious, intrigued, or maybe even afraid of what our future will be like. Therefore, we need hope. In this editorial we want to stress the importance of hope and argue that people should not be left alone with suspicion, fear and doubt about how technology will change their future.
Towards the standardised set of stimuli for the uncanny valley phenomenon studies
Authors: Łupkowski Paweł , Ratajczyk Dawid
Published: May 2023

This paper presents a pre-validated set of 12 static 3D stimuli for the needs of uncanny valley-related studies. We provide the set along with guidelines on how to use it, which are based on the aggregated data analysis covering previous laboratory and online studies. Guidelines cover the models’ characteristics (in terms of human-likeness and other visual traits), issues related to the stimuli presentation and study groups. As the set is publicly available, we believe that it enhances future studies aimed at replicating the uncanny valley effect.

Authors: Naranjo Arango Yonatan Andres , Martínez Ríos John Byron , Veintemilla Granados Galo , Martínez Parra Valentina
Published: May 2023

Antecedentes: La hipertensión pulmonar persistente del recién nacido es un síndrome caracterizado por falla respiratoria aguda con hipoxemia ocasionado por el aumento de la resistencia vascular pulmonar de forma sostenida, con hipoxemia acentuada y cianosis generalizada. Dentro de las causas raras se encuentra el secuestro pulmonar. Reporte de caso: El presente caso es un paciente neonato, sin controles prenatales, quien cursó con un cuadro de dificultad respiratoria dependiente de ventilación mecánica invasiva prolongada, con sospecha de neumonía por los hallazgos en la radiografía de tórax y TAC, sin mejoría al tratamiento antibiótico y con deterioro del estado cardiorrespiratorio. Evaluado por cardiología y neumología pediátrica se halló la presencia de ductus arterioso persistente grande con repercusión hemodinámica, e hipertensión pulmonar persistente. Se realiza angio TAC de tórax con evidencia de secuestro pulmonar intralobar en pulmón derecho y circulación aberrante. Requirió resección quirúrgica. Conclusiones: La hipertensión pulmonar persistente es un síndrome con elevada morbilidad y mortalidad en los neonatos, por lo que es necesario realizar un diagnóstico temprano, identificar la etiología y tratarlo adecuadamente basado en medidas de soporte ventilatorio y vasodilatadores con el fin de disminuir la resistencia vascular pulmonar.
Diagnóstico tardío de ingestión de cuerpo extraño en un niño: reporte de caso
Authors: Guzmán Vélez Jorge Enrique , Navarro Holguín Melissa , Montoya Rúa Daniela , Lince Restrepo Manuela
Published: May 2023

Antecedentes: la ingesta de cuerpos extraños es frecuente en la población pediátrica, puede presentarse con una gran variedad de síntomas y en ocasiones su diagnóstico puede ser tardío. Reporte de caso: paciente masculino de 2 años, sin antecedentes personales de relevancia con historia de 4 meses de evolución de estridor inspiratorio y tos húmeda. Al examen físico se encontraba con signos de dificultad respiratoria y estridor inspiratorio continuo. Inicialmente fue diagnosticado con laringotraqueítis aguda y tratado con nebulizaciones hipertónicas y esteroide intravenoso sin mejoría aparente de los síntomas. Se realizó radiografía de tórax en proyecciones AP y lateral que mostró cuerpo extraño de características metálicas localizado en la región superior del esófago. Se realizó endoscopia digestiva superior obteniendo una moneda. Discusión: la ingesta de cuerpos extraños en niños pequeños en común. La mayoría logran pasar el tracto gastrointestinal sin generar daño, sin embargo, algunos cuerpos extraños pueden causar morbilidad significativa. El diagnóstico puede retrasarse especialmente si la ingesta no fue identificada por otra persona o si no se tiene en cuenta esta condición en los diagnósticos diferenciales. Conclusión: este reporte de caso destaca la importancia de reconocer los síntomas respiratorios raros y a menudo olvidados causados por la ingestión de cuerpos extraños para evitar retrasos en el diagnóstico y su tratamiento.

INTRODUCTION:

We determined adverse events after 4 doses of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccine in those with inflammatory bowel disease (IBD), associations between antibodies and injection site reactions (ISR), and risk of IBD flare.

METHODS:

Individuals with IBD were interviewed for adverse events to SARS-CoV-2 vaccine. Multivariable linear regression assessed the association between antibody titers and ISR.

RESULTS:

Severe adverse events occurred in 0.03%. ISR were significantly associated with antibody levels after the fourth dose (geometric mean ratio = 2.56; 95% confidence interval 1.18–5.57). No cases of IBD flare occurred.

DISCUSSION:

SARS-CoV-2 vaccines are safe for those with IBD. ISR after the fourth dose may indicate increased antibodies.

Generic medication is a product that contains the same active substance and pharmaceutical characteristics as brand-name medications. Generic medications are cost-effective and comparable to brand-name medications in terms of clinical endpoints. However, the use of generic medications instead of brand-name medications is a debatable issue among patients and healthcare providers. Two patients with essential hypertension experienced side effects after switching to different generic antihypertensives (one generic medication to another generic medication). Adverse drug reactions, including, hypersensitivity, side effects, and intolerance, should be identified through present and past medical history and clinical characteristics. The adverse drug reactions in both patients were more likely to be side effects of the medications after switching to different generic antihypertensives produced by different companies (patient 1: enalapril and patient 2: amlodipine). The side effects were possibly caused by the different inactive ingredients or excipients. These two case reports emphasise the importance of monitoring adverse drug reactions throughout the course of treatment and communicating with patients prior to switching to a new generic medication.

The article presents results of retrospective analysis of data from tests related to the diagnostics and inspections of vehicles as part of official technical tests carried out in 2016–2022, among the others, at the Automotive Service Centre for Disabled Persons operating at the Motor Transport Institute. The current trend shows that the quality of technical inspection is regularly improved by introducing legal standardization and standards for assessing the technical condition of a vehicle intended for a disabled driver. The subject of technical tests should therefore be adaptive devices designed to adapt the vehicle for their safe use by these people. As a part of this study, an analysis of the literature in the area of mobility and vehicle adaptation was also carried out, indicating the current directions of analyses and technical standards for adaptive devices.
GPU acceleration of Nystrom type method for solving singular integral equations in H-polarized EM waves scattering by strip gratings
Authors: Kaliberda Mstislav E. , Lytvynenko Leonid M. , Pogarsky Sergey A.
Published: May 2023

In this paper, we propose the use of the graphics processing units (GPUs) for acceleration of solution of the H-polarized electromagnetic waves scattering by strip gratings. The approach combines the boundary integral equation method with the Nystrom-type discretization of singular integral equations and is realized with the use of C++ and OpenCL. The elements of the matrix of the resulting system of equations can be calculated independently and, thus, in parallel. The calculation time of the proposed parallelized algorithm on GPU is compared to standard serial algorithm executed on CPU. We considered gratings of graphene strips in vacuum and inside a dielectric slab. The acceleration is up to 35–55 times for the gratings in vacuum and up to 80–140 times for the gratings of 5–20 strips inside the dielectric slab.
Ferrous and manganese oxalate for efficient heterogenous-Fenton degradation of organic pollutants: composite active site and mechanism perception

Composite heterogeneous catalysts of ferrous and manganese oxalate (FeC2O4/MnC2O4) were prepared via simple chemical co-precipitation. The catalytic performance was evaluated by determining the degradation efficiency of rhodamine B (RhB). Under optimum conditions, 6-1FeMn showed the best catalytic performance, and the degradation efficiency exceeded 95 % within 2 min, which was 1.4 times more than ferrous oxalate. Under a wide pH range (1–8), 6-1FeMn showed high degradation efficiency for RhB with good recyclability and reusability. By characterizing the catalysts before and after the reaction and analyzing the degradation process, a possible mechanism was proposed: Mn2+ and Fe2+ synergistically catalyzed and produced a large number of hydroxyl radicals (·OH) by forming a composite active site for efficient reactivation. Mn3+ accelerated the transfer between Fe2+ and Fe3+. In addition, C2O4
2− reactivated the active site in situ and enhanced the catalytic properties. This study provides new insight into the catalytic degradation of organic dyes using composite heterogeneous Fenton catalysts.
Building sustainability research competencies through scaffolded pathways for undergraduate research experience
Authors: Elder Sara , Wittman Hannah , Giang Amanda
Published: May 2023

Addressing complex socio-ecological challenges, from climate change to biodiversity loss, requires collaborative co-creation and application of knowledge that bridges disciplines and diverse research communities. New models of research training are needed that emphasize these competencies and are inclusive of students from underrepresented groups in academia. This article presents learnings from a 2-year pilot project at the University of British Columbia in which we created a new course-based undergraduate interdisciplinary research experience in socio-ecological systems designed to address these twin problems. We evaluated the linkages between pedagogical design, achievement of sustainability research competencies, and overcoming barriers to research participation. We find that mentored and scaffolded learning-by-doing supported by peer group-based learning was successful in catalyzing transformative interdisciplinary learning for students. Our results emphasize the importance of scaffolding at multiple levels to remove barriers to accessing a first research experience and providing an introductory opportunity for students to build research self-efficacy and better equip students for independent research. Shifting toward pedagogies that build sustainability-related competencies and that remove barriers to access is high-reward and thus requires institutional support and investment.
El desarrollo de habilidades en el trabajo matemático: el caso de Lucas, un futuro profesor de matemática, en su práctica profesional
Authors: Verdugo-Hernández Paula , Espinoza-Vásquez Gonzalo
Published: May 2023

[Objetivo] Este trabajo busca caracterizar el trabajo matemático que el futuro profesor de matemática privilegia en el contexto de sus prácticas tempranas, en su formación inicial, particularmente, en la última de estas instancias (práctica profesional), a través de sus propuestas de enseñanza, en relación con el desarrollo de las habilidades disciplinares (matemáticas) establecidas por el currículo chileno. [Metodología] Se trata de un estudio cualitativo, en el cual se analizó la implementación de una clase en línea sobre medidas de posición (cuartiles) y su correspondiente planificación. Se realizó el examen de contenido sobre las tareas matemáticas incluidas en la clase, respecto a sus características matemáticas y las habilidades disciplinares declaradas en la planificación. [Resultados] Los resultados muestran que el trabajo matemático privilegiado en dichas tareas aborda habilidades diferentes a la planificada y que la baja participación de los estudiantes en el contexto de la clase en línea lleva al futuro profesor a resolver por sí mismo las asignaciones que propone, lo que restringe el desarrollo de las habilidades matemáticas del currículo, contempladas en la planificación. [Conclusiones] El trabajo matemático propuesto en las tareas seleccionadas promueve el uso de representaciones semióticas y aspectos operacionales de los cuartiles, pero queda desvinculado del desarrollo de las habilidades disciplinares. Finalmente, se reflexiona en torno a cómo se produce la selección de tareas que comprometan a los estudiantes y que permitan el desarrollo de las habilidades planificadas por parte del futuro profesor, considerando lo que espera desarrollar durante la enseñanza y motiva la observación de los procesos formativos de los docentes.

[Objective] From 1988 to 2018, high school students in Costa Rica had to pass a final exam to graduate from high school and be eligible for public university education. In this context, students had to choose a national science test from the areas of physics, chemistry, and biology. Historically, chemistry was the least chosen (4-6 %) of those sciences. On the other hand, there is a need -at the national level- to increase interest in careers related to STEM (Sciences, technology, engineering, and mathematics). [Methodology] Under both premises, in 2016, the first national camp (called Quimi Camp) to promote scientific vocations was held to encourage high school students in Costa Rica to choose chemistry. Quimi Camp is an event supported by the OLCOQUIM National Chemistry Olympiad and the OLCOCI National Science Olympiad, which are in turn organized by the five Costa Rican State universities and the LANOTEC CENAT National Nanotechnology Laboratory at the National Center of High Technology, with the consent of the Ministry of Education (MEP) and the Ministry of Science, Innovation, Technology and Telecommunication (MICITT). The participating students made the final evaluation of this event. [Results] The results showed an excellent perception of the event regarding its organization and content. [Conclusions] Quimi Camp promoted students' vocation for science and engineering and positively influenced the selection of a University Career in STEM.
