A proposta deste artigo é analisar como as tecnologias digitais contribuíram para ressignificar identidades e para potencializar a representatividade dos alunos do Colégio Estadual do Paraná que participaram das manifestações dos professores da rede estadual de ensino durante a greve desta categoria, em 2015. O recorte da investigação teve como foco a apropriação da linguagem audiovisual pelos estudantes e sua interface com o universo tecnológico e com a escola. O estudo utilizou como recurso metodológico uma entrevista semiestruturada com um grupo de alunos e a base teórica tensionou conceitos de Martín-Barbero (2004 e 2014), Orozco Gómez (2006) e Stuart Hall (2014), como comunicação e educação, descompasso, destempo, reconhecimento e identidade. As considerações finais apontam a tecnologia como uma das trilhas para os novos modos de sentir e de aprender, potencializando, assim, a ressignificação das identidades desses jovens e suas representatividades por meio do reconhecimento, do pertencimento e das novas formas de relação professor e aluno.

Abstract
The proposal of this paper is to analyse how the digital techonologies contributed to resignify identities and potentialize the representativity of the students of Colégio Estadual do Paraná who participated at the manifestations of teachers of the State teaching system during the strike of the category, in 2015. The research focused on the appropriation of audiovisual language by the students and its interface with the techonological universe and the school. The study used as methodological resource a semi-structured interview with a group of students and the theoretical basis brought together concepts from Martín-Barbero (2004 e 2014), Orozco Gómez (2006) e Stuart Hall (2014), such as communication and education, mismatches, destempo, recognition and identity. The final considerations point technology as one of the tracks to the new ways of feeling and learning, potentiating, therefore, the resignifying of identities of these young men and women and their representativities through recognition, belonging and new possibilites for the relation teacher-student.
El terror en el cine argentino y brasileño en los años cincuenta. Relecturas de monstruos importados y violencia sexual: entre la ley, el psicoanálisis y la mandinga // Horror in Argentinian and Brazilian cinema in the fifties. Readings of imported monste
Authors: Marino Cecilia Gil 
Published: March 2021

Durante el período denominado clásico, en Argentina y Brasil, el terror se expresó a través y en hibridez con otros géneros más populares en la época, configurándose versiones vernáculas de suma particularidad del policial, del noir, del melodrama fantástico, del gótico, entre otros, y así, articularon un repertorio de miedos, ansiedades, represiones y fascinaciones que dialogaban con los discursos sociales civilizatorios. El asesino serial, el pedófilo y el monstruo, por un lado, constituirían la figura de la alteridad frente al ciudadano civilizado. Por el otro, su naturaleza “anómala” manifestaba las represiones y frustraciones masculinas en un orden patriarcal rigurosamente establecido.
A partir del análisis de tres películas de la época, este trabajo busca indagar sobre las imágenes de la violencia sexual y los femicidas en los primeros años de la década de 1950 en clave comparativa entre el cine argentino y brasileño para pensar las imágenes de los monstruos sociales y los modos de lidiar con ella a través de la ley y de las interpretaciones psicoanalíticas y místico-religiosas en las explicaciones de las anomalías del orden. Estos filmes son Caiçara (Adolfo Celi, 1950), Vampiro negro (Vignoly, 1953) y Si muero antes de despertar (Carlos Hugo Christensen, 1952).

Published: March 2021

In two proof‐of‐concept studies, we established and validated the Bacterial Growth Inhibition Screen (BGIS), which explores recombinant protein toxicity inEscherichia colias a largely overlooked and alternative means for basic characterization of functional eukaryotic protein domains. By applying BGIS, we identified an unrecognized RNA‐interacting domain in the DEK oncoprotein (this study) and successfully combined BGIS with random mutagenesis as a screening tool for loss‐of‐function mutants of the DNA modulating domain of DEK [1]. Collectively, our findings shed new light on the phenomenon of recombinant protein toxicity inE. coli. Given the easy and rapid implementation and wide applicability, BGIS will extend the repertoire of basic methods for the identification, analysis and unbiased manipulation of proteins.

Screening for early‐stage disease is vital for reducing colorectal cancer (CRC)‐related mortality. Methylation of circulating tumor DNA has been previously used for various types of cancer screening. A novel cell‐free DNA (cfDNA) methylation‐based model which can improve the early detection of CRC is warranted. For our study, we collected 313 tissue and 577 plasma samples from patients with CRC, advanced adenoma (AA), non‐AA and healthy controls. After quality control, 187 tissue DNA samples (91 non‐malignant tissue from CRC patients, 26 AA and 70 CRC) and 489 plasma cfDNA samples were selected for targeted DNA methylation sequencing. We further developed a cfDNA methylation model based on 11 methylation biomarkers for CRC detection in the training cohort (area under curve [AUC] = 0.90 (0.85–0.94]) and verified the model in the validation cohort (AUC = 0.92 [0.88–0.96]). The cfDNA methylation model robustly detected patients pre‐diagnosed with early‐stage CRC (AUC = 0.90 [0.86–0.95]) or AA (AUC = 0.85 [0.78–0.91]). Here we established and validated a non‐invasive cfDNA methylation model based on 11 DNA methylation biomarkers for the detection of early‐stage CRC and AA. The utilization of the model in clinical practice may contribute to the early diagnosis of CRC.

AbstractConventional flexible pressure sensors are not suitable for high‐pressure applications due to their low saturation pressure. In this study, an ultra‐wide range pressure sensor is designed based on the optimized microstructure of the polyimide/carbon nanotubes (PI/CNT) nanocomposite film. The sensing range of the pressure sensor is expanded by adopting polyimide (PI) with a high elastic modulus as a matrix material and its sensitivity is improved through functional sensing film with tip‐flattened microdome arrays. As a result, the pressure sensor can measure a wide pressure range (≈ 0–3000 kPa) and possesses the sensitivity of ≈ 5.66 × 10−3–0.23 × 10−3 kPa−1 with high reliability and durability up to 1000 cycles. The proposed sensor is integrated into the hand and foot pressure monitoring systems for workout monitoring. The representative values of the pressure distribution in the hands and feet during the powerlifting are acquired and analyzed through Pearson's correlation coefficient (PCC). The analyzed results suggest that the pressure sensor can provide useful real‐time information for healthcare and sports performance monitoring.

AbstractThe direct and rapid formation of a precise pattern of metallic nanoparticles (NPs) supported and/or embedded in a flexible polymeric substrate is not easy to achive. However, the development of simpler and more reliable procedures is still highly desirable. This paper presents an innovative technique, simple, cheap, and robust, for producing a self‐supported sheet of polydimethylsiloxane (PDMS) embedding periodic arrays of clusters of nickel nanoparticles (NiNPs). The method uses the pyroelectric effect in a periodically poled lithium niobate (PPLN) crystal for producing a surface charge template able to address the patterning of the NPs by applying a simple thermal stimulation. The key advantages are rapidity, single‐step, and electrode‐free operation. The reliability of the technique is demonstrated for different geometries that are called here “dots” and “grid” and for three different periods 50, 200, and 400 µm. The resulting sheets are attractive for both their flexibility and magnetic properties that can be used for detection, entrapment, and/or patterning of micro‐ and nanoparticles in various fields such as microfluidics and biomedicine.

AbstractThe near‐band‐edge emission of Sb2Se3 microcrystals is studied in detail under high photoluminescence excitation density using a pulsed UV laser (λ = 266 nm, pulse width 0.6 ns). Based on the peak energy positions and the excitation power density and temperature dependencies (T = 3–110 K) of the photoluminescence spectra, the emission is interpreted as a recombination of two pairs (A and B) of free excitons and biexcitons appearing because of valence band splitting. The magnitude of the valence band splitting due to the crystal field (Δcr = 20–22 meV) is estimated in the Brillouin zone center. At T = 3 K, the A and B biexciton emission at 1.302 and 1.322 eV, respectively, and the A and B free exciton emission at 1.311 and 1.333 eV, respectively, are observed. The binding energy of A and B biexcitons is 9 and 11 meV, respectively, and the binding energy of A free exciton is 6 meV. The activation energy of thermal quenching for all observed peaks is 20 meV.

Published: March 2021

AbstractIn high‐capacity layered oxide cathode materials, utilization of lattice oxygen as a redox center is considered to be one of the most promising approaches to overcome the capacity limitation set by conventional transition metal redox centers. However, rapid material degradation is often associated with oxygen oxidation, leading to formidable challenges in utilizing oxygen redox. Further mechanistic understanding of the oxygen activities thus becomes critical to better control oxygen redox reactions. This review summarizes recent advances for investigating oxygen redox reactions in cathode materials from a multiscale perspective, i.e., from the atomistic level to the microstructure regime. First the mechanistic aspects of oxygen redox and the consequences of this reaction on various electrode degradation pathways during battery operation (e.g., oxygen loss, transition metal migration, irreversible phase transition), relating structural changes at the crystallographic scale to those at the macro scale, are discussed. Then recent developments based on atomic and microstructure modifications that are promising for improving the reversibility of oxygen redox reaction or mitigating the harmful processes arising from oxidation of the oxygen centers under high operating voltage are recounted. The analysis is concluded with a commentary on further research directions toward optimizing the oxygen activity for high‐capacity charge storage.

Published: March 2021

AbstractDue to the recent innovations in computer technology, the emerging field of materials informatics has now become a catalyst for a revolution of the research paradigm in materials science. Knowledge graphs, which provide support for knowledge management, are able to collectively capture the scientific knowledge from the vast collection of research articles and accomplish the automatic recognition of the relationships between entities. In this work, a materials knowledge graph, named MatKG, is constructed, which establishes a unique correspondence between subjects and objects in the materials science area. An emphasis is placed on the disambiguation of authors, addressed by a deduplication model based on machine learning and matching dependencies algorithms. Specifically, MatKG is applied to perform tracking on research trends in the study of LiFePO4 and to automatically chronicle the milestones achieved so far. It is believed that MatKG can serve as a versatile research platform for amalgamating and refining the scientific knowledge of materials in a variety of subfields and intersectional domains.

AbstractMounded, tallgrass prairie ecosystems are a unique, endangered ecosystem due to severe disturbance for agricultural production and/or urban expansion. Limited research exists on earthworm (Lumbricus terrestris) dynamics in mounded, tallgrass prairies, particularly in the Ozark Highlands region of northwestern Arkansas. The objectives of this study were to evaluate the effects of soil moisture regime (SMR), landscape position (LP), and sample date on earthworm densities in the top 20 cm of soil in two mounded, native prairies in the Ozark Highlands region of northwestern Arkansas. Juvenile and total earthworm densities were five times greater (P < .05) in the udic‐ and aquic‐inter‐mound combinations than any other SMR‐LP combination in October 2018 and May 2019, respectively. Adult earthworm densities were two times greater (P < .05) in the aquic‐inter‐mound at Searles Prairie than any other SMR‐LP combination in either mounded prairie. Juvenile earthworm densities were three times greater (P < .05) in May 2019 than in May 2018 at Chesney Prairie, but adult and total earthworm density did not change over the same period of time. Combined across all data, juvenile and total earthworm densities were positively correlated (P < .05) with moisture (r = .33 and .34, respectively), Ca (r = .20 and .21, respectively), and Fe (r = .53 and .52, respectively), but negatively correlated (P < .05) with Mn (r = –.34 and –.32, respectively). Results of this study extended overall understanding of earthworm population distributions and dynamics in mounded prairie systems.

AbstractCongenital myopathies (CMs) are a heterogeneous group of inherited muscle disorders characterized by muscle weakness at birth, while limb‐girdle muscular dystrophies (LGMD) have a later onset and slower disease progression. Thus, detailed clinical phenotyping of genetically defined disease entities are required for the full understanding of genotype–phenotype correlations. A recently defined myopathic genetic disease entity is caused by bi‐allelic variants in a gene coding for pyridine nucleotide‐disulfide oxidoreductase domain 1 (PYROXD1) with unknown substrates. Here, we present three patients from two consanguineous Turkish families with mild LGMD, facial weakness, normal CK levels, and slow progress. Genomic analyses revealed a homozygous known pathogenic missense variant (c.464A>G, p.Asn155Ser) in family 1 with two affected females. In the affected male of family 2, we found this variant in a compound heterozygous state together with a novel frameshift variant (c.329_332delTCTG, p.Leu112Valfs*8), which is the second frameshift variant known so far in PYROXD1. We have been able to define a large homozygous region in family 1 sharing a common haplotype with family 2 in the critical region. Our data suggest that c.464A>G is a Turkish founder mutation. To gain deeper insights, we performed a systematic review of all published PYROXD1‐related myopathy cases. Our analysis showed that the c.464A > G variant was found in 87% (20/23) of the patients and that it may cause either a childhood‐ or adult‐onset phenotype, irrespective of its presence in a homozygous or compound heterozygous state. Interestingly, only four patients had elevated CK levels (up to 1000 U/L), and cardiac involvement was found in few compound heterozygous cases.

AimThe global outbreak of coronavirus disease (COVID‐19) has had widespread effects on clinical practice, and is reportedly associated with reduced percutaneous coronary intervention (PCI) rates in the US and Italy. This study aimed to ascertain the influence of the COVID‐19 outbreak on PCI practice in Japan.MethodsIn a retrospective analysis of claims data from National Health Insurance and Later‐Stage Elderly Healthcare System enrollees in Kobe City, Japan, we examined the changes in PCI incidence before and during the COVID‐19 outbreak. Percutaneous coronary intervention incidence during the COVID‐19 outbreak in 2020 was compared with that of the same (pre‐outbreak) period in 2019 using a Poisson regression analysis with the monthly number of PCIs as the dependent variable.ResultsA total of 639 patients underwent PCI in Kobe City between February and May 2020. The results showed a 19% reduction in all PCI procedures during the outbreak relative to the pre‐outbreak period (P = 0.001). There were no significant changes in non‐elective PCIs for acute coronary syndrome (ACS) cases, but a 25% reduction in elective PCIs for non‐ACS cases (P < 0.001).ConclusionsThe COVID‐19 outbreak was associated with a decline in elective PCIs for non‐ACS cases, but did not appear to influence non‐elective PCIs for ACS cases in Japan.

AbstractImparting mesopores to organic cages of an intrinsic microporous nature to build up hierarchically porous cage soft materials is a grand challenge and will reshape the property and application scope of traditional organic cage molecules. Herein, we discovered how to engineer mesopores into microporous organic cages via their host–guest interactions with long chain ionic surfactants. Equally important, the ionic head of surfactants equips the supramolecularly assembled porous structures with charge‐selective uptake and release function in solution. Interestingly, such hierarchically porous organic cage can serve as a nanoreactor once trapping enzymes within the cavity, which show 5‐fold enhanced activity of enzymatic catalysis when compared with the free enzymes.
The compressive property of a fiber‐reinforced resin beetle elytron plate and its influence mechanism

Published: March 2021

AbstractTo develop composite material beetle elytron plates (BEPs), short basalt fiber‐reinforced epoxy resin BEPs with hollow trabeculae and honeycomb walls were fabricated exploratively. Through comparison with honeycomb plates (HPs) with the same wall thickness, the basic mechanical performance, failure mode and influence mechanism were studied via out‐of‐plane compression tests. The results show that compared with HPs, the specific strength and energy consumption per volume of BEPs can be at least 18% and 112% higher, respectively; however, the increase is less than half that of BEPs made of ductile materials. The former is due to the synergistic mechanism of the trabecular‐honeycomb structure in the BEP core layer, which endows the composite BEPs with better ductility than HPs, while the latter is caused by the prominent brittleness of the composite material used in this study. Additionally, the height‐to‐thickness ratio of the plate honeycomb wall in this article is not large enough. Thus, the core has great rigidity and fails to buckle in experiments; instead, shear failure of the core material occurs. This study reveals for the first time the mechanical compression properties and failure mechanism of brittle material BEPs and shows a direction for developing BEPs in similar material types.

AbstractObjectiveTo identify circular RNAs as candidates for differential expression in the middle temporal (MT) cortex in a well‐characterized cohort with contrasting Alzheimer disease (AD) pathology and cognition. Top screen candidates were assessed for proof of circularity and then quantified by qPCR in a larger number of samples.MethodsAn initial RNA sequencing screen was performed on n = 20 frozen human tissue samples. Filters were applied to select candidate circular RNAs for further investigation. Frozen human tissue samples were selected for global AD pathology burden and global cognition scores (n = 100). Linear and divergent primers were used to assess circularity using RNaseR digestion. RT‐qPCR was performed to quantify relative hsa_circ_0131235 abundance.ResultsEleven circular RNAs were selected for further investigation. Four candidates produced circular RNA primers with appropriate efficiencies for qPCR. RNaseR treatment and analysis by both basic PCR and qPCR confirmed hsa_circ_0131235 circularity. There was a significant main effect of AD pathology on hsa_circ_0131235 expression.ConclusionsElevated hsa_circ_0131235 expression in the MT cortex was significantly associated with AD pathology.

AbstractObtaining a correct intraosseous epidermal cyst diagnosis is difficult due to the extreme rarity of this cyst. Further, the clinical manifestations and radiographic findings are very similar to those of a malignancy or infection. Early histopathological analysis is required for accurate diagnosis and for avoiding unnecessary antibiotic administration and amputation.
