Published: July 2023

In this study, magnetic resonance imaging (MRI) based on a deep learning algorithm was used to evaluate the clinical effect of the small-incision approach in treating proximal tibial fractures. Super-resolution reconstruction (SRR) algorithm was used to reconstruct MRI images for analysis and comparison. The research objects were 40 patients with proximal tibial fractures. According to the random number method, patients were divided into a small-incision approach group (22 cases) and an ordinary approach group (18 cases). The peak signal-to-noise ratio (PSNR) and the structural similarity index (SSIM) of the MRI images before and after the reconstruction of the two groups were analyzed. The operative time, intraoperative blood loss, complete weight-bearing time, complete healing time, knee range of motion, and knee function of the two treatments were compared. The results showed that after SRR, the PSNR and SSIM of MRI images were 35.28 and 0.826 dB, respectively, so the MRI image display effect was better. The operation time in the small-incision approach group was 84.93 min, which was significantly shorter than that in the common approach group, and the intraoperative blood loss was 219.95 mL, which was significantly shorter than that in the common approach group (P < 0.05). The complete weight-bearing time and complete healing time in the small-incision approach group were 14.75 and 16.79 weeks, respectively, which were significantly shorter than those in the ordinary approach group (P < 0.05). The half-year knee range of motion and 1-year knee range of motion in the small-incision approach group were 118.27° and 128.72°, respectively, which were significantly higher than those in the conventional approach group (P < 0.05). After 6 months of treatment, the rate of good treatment was 86.36% in the small-incision approach group and 77.78% in the ordinary approach group. After 1 year of treatment, the rate of excellent and good treatment was 90.91% in the small-incision approach group and 83.33% in the ordinary approach group. The rate of good treatment for half a year and 1 year in the small incision group was significantly higher than that in the common approach group (P < 0.05). In conclusion, MRI image based on deep learning algorithm has a high resolution, good display effect, and high application value. The small-incision approach can be applied to the treatment of proximal tibial fractures, which showed good therapeutic effects and a high positive clinical application value.

Published: July 2023

Wheat pests and diseases are one of the main factors affecting wheat yield. According to the characteristics of four common pests and diseases, an identification method based on improved convolution neural network is proposed. VGGNet16 is selected as the basic network model, but the problem of small dataset size is common in specific fields such as smart agriculture, which limits the research and application of artificial intelligence methods based on deep learning technology in the field. Data expansion and transfer learning technology are introduced to improve the training mode, and then attention mechanism is introduced for further improvement. The experimental results show that the transfer learning scheme of fine-tuning source model is better than that of freezing source model, and the VGGNet16 based on fine-tuning all layers has the best recognition effect, with an accuracy of 96.02%. The CBAM-VGGNet16 and NLCBAM-VGGNet16 models are designed and implemented. The experimental results show that the recognition accuracy of the test set of CBAM-VGGNet16 and NLCBAM-VGGNet16 is higher than that of VGGNet16. The recognition accuracy of CBAM-VGGNet16 and NLCBAM-VGGNet16 is 96.60 and 97.57%, respectively, achieving high precision recognition of common pests and diseases of winter wheat.
Probabilistic derivation of droplet velocity using quadrature method of moments
Authors: Jasim Noor M.
Published: July 2023

Accurately prediction of dispersion and polydispersity of droplet flow is not a trivial task due to the complex behavior of the droplet size distribution (DSD) and the strong state of the instantaneous velocity of a droplet on the shape and size of the droplet. Describing the distribution of sizes and velocities of droplets initially formed in sprays is an essential piece of information needed in spray modeling, which is used to define the initial state of the spray droplets in the downstream two-phase flow fields’ predictive computations. The predictive model for the droplet size and velocity distributions in sprays is formulated as the droplet’s velocity magnitude has a power–law relationship with the droplet in this study. The present model incorporates the deterministic and stochastic aspects of the spray formation process. The quadrature method of moments (QMOM) is applied to solve numerically the transport equations of the probability density function coupled with conserved source terms incompressible Navier-Stokes equations for the liquid phase. The sub-models are connected by different source terms signifying the liquid-gas interaction. Equations of transport for spray moments are derived from DSD, and closure is attained using a gamma distribution. The integer spray moments concerning the volume are used to construct the continuous distribution of QMOM. In contrast, the velocity moments are used to determine the droplet velocity as a constant function of the droplet diameter. The model is first applied to simulate a diesel spray tip penetration under nonreactive conditions with different droplet velocity profiles to validate the approach with experimental data. An additional case of a liquid nitrogen spray is applied to show the gamma distribution’s ability to describe spray drop size distribution. The model generally predicts reasonable agreement with the experimental for both cases.

Published: July 2023

The hydrodynamics of airlift bioreactors, which offer an interesting alternative to conventional stirred-tank bioreactors, has generally been evaluated using experimental approaches, requiring time, energy, and reagents. However, computational fluid dynamics (CFD) has emerged as an important and valuable tool for the analysis and design of these devices, saving time and experimental effort, while providing a large amount of information. In this study, four geometries of a square cross-section 10-L split airlift bioreactor operating with distilled water were simulated using CFD, and the hydrodynamics variables gas hold-up and liquid velocity were evaluated. CFD satisfactorily predicted the hydrodynamic parameters, when compared to experimental data, allowing adequate prediction of the shear rate distribution in airlift bioreactors. The results indicated that different shear rate distributions were obtained by geometric modifications in the bioreactor, showing that its design should be considered to satisfy different specific bioprocess requirements.

Para isso, visito as fronteiras da memória e do esquecimento nas falas que seguem seus caminhos, nos discursos sobre e dos brasileiros, e sobre o Brasil. Sentidos latentes, que se tensionam entre a estabilidade e o equívoco.
PRESENCES TSIGANES EN FRANCE (ET DIVERS PAYS D’EUROPE): LE TRAITEMENT POLITIQUE ET LA PERCEPTION DE L’AUTRE
Authors: Filhol Emmanuel
Published: July 2023

L’histoire des Tsiganes en Europe remonte à la fin du Moyen Âge. La très grande diversité des groupes familiaux, sous les désignations autonymes qu’ils se donnent (Manouches, Roms, Sinté, Sinti, Gitans, Gypsies, Travellers, Yéniches, Voyageurs…) ou selon les noms plus ou moins péjoratifs qu’on leur attribue (Égyptiens, Bohémiens, Romanichels, Nomades) s’accompagne d’une pluralité des façons d’être au monde et de pratiques de l’espace, entre circulations et ancrages. En dépit de leur valorisation auprès des populations médiévales et à la Renaissance, la politique qu’adoptent les pouvoirs publics à l’égard des minorités tsiganes témoigne par la suite de mesures constantes discriminatoires et persécutives. Rien d’étonnant alors si, à quelques exceptions près, la langue romani, objet d’une non reconnaissance officielle, en France notamment, s’est vue réduite à un silence. La production iconographique consacrée aux Tsiganes révèle malgré tout un mélange contradictoire d’attitudes faites d’hospitalité et d’hostilité.
ENTRE FINAIS DE SÉCULOS: A CONDIÇÃO FEMININA E SUA REPRESENTAÇÃO FICCIONAL EM KATE CHOPIN E LÍDIA JORGE
Authors: Silvestre Marcela Cucci , Dunder Mauro
Published: July 2023

Uma das questões que se têm colocado, no que diz respeito à constituição do cânone literário, é a da representatividade feminina. É seguro afirmar que, ao longo dos séculos, a produção literária de autoria feminina vem sendo deixada em condição de marginalidade, em relação às obras de autoria masculina. Uma das consequências dessa relação de desigualdade é o surgimento, em meados da década de 1980, da Ginocrítica, vertente da Crítica Literária Feminista que traz ao centro da discussão a questão da existência de mulheres que escrevem - particularmente sobre questões que dizem respeito à condição feminina nas diferentes sociedades. Sob tal perspectiva, este artigo discute, comparativamente, a representação da mulher e de sua condição em dois contos de tempos e culturas distintos: "The Story of an Hour" (1894), da norte-americana Kate Chopin (1851-1904), e "Marido" (1996), da portuguesa Lídia Jorge (1946), levando em conta as estratégias estéticas e narrativas de que lançam mão para discutir, em seus contextos, diferentes formas de opressão a que a sociedade submete as mulheres. Servem de arcabouço teórico as reflexões de, entre outros, Gilbert e Gubar (1984), Muecke (1995) e Bachelard (2003).
THE ROLE OF NARRATIVE STRUCTURE IN THE ACQUISITION OF EUROPEAN PORTUGUESE PERFECTIVE AND IMPERFECTIVE MORPHOLOGY BY L1 MANDARIN CHINESE LEARNERS
Authors: Yang Aoran , Zhu Linke
Published: July 2023

The study of the acquisition of L2 tense-aspect and the development of aspectual distinctions has been conducted according to various theoretical hypotheses, among which the Discourse Hypothesis stands out nowadays. In order to examine the relationship between the use of perfective/imperfective morphology and the narrative grounding, the present study is oriented by three research questions: (1) what is the temporal base like in the past narratives produced by L1 Mandarin Chinese learners of European Portuguese? (2) is the choice of perfective and imperfective verbal morphology influenced by the narrative grounding? (3) do the learners of different proficiency levels mark the narrative grounding with different verbal forms? On the basis of a quantitative analysis on the data collected from the narratives produced by 12 L1 Mandarin Chinese learners of European Portuguese, the results revealed that the temporal base for narratives is clearly perfective-imperfective and that the foreground was mostly marked by the perfective morphology, whereas the imperfective tended to be used to mark the background, irrespective of the learners’ proficiency levels.

A SÁTIRA COMO INSTRUMENTO DE DENÚNCIA POLÍTICA E LUTA SOCIAL NA OBRA LITERÁRIA DE JOANIM PEPPERONI, PhD
Authors: Mendes Junior Jerson Oliveira , Arendt João Cláudio
Published: July 2023

Este artigo procura analisar a produção literária de Joanim Pepperoni, PhD, destacando o recurso da sátira como instrumento de denúncia e luta social. A análise recai sobre a retomada do mito medieval da Terra da Cocanha como escolha estratégica para ambientar poemas e ações das personagens, apontando o uso da paródia de textos tradicionais, consagrados pela literatura, e os de domínio popular, como recurso constante para desenvolver seu projeto literário. Nesse sentido, o texto destaca e analisa a sátira política em poemas envolvendo questões tanto da localidade do autor (a região da Serra Gaúcha), quanto as de âmbito nacional (das eleições presidenciais de 2018 à atual gestão). A base teórica e crítica do trabalho advém de estudos realizados por Propp (1992), Franco Júnior (1998), Sant’Anna (2003), Cei e Pelinser (2017) e Arendt (2020).
UMA VIAGEM AO PATÍBULO: a teoria do romance de Ernesto Sabato
Authors: Hülsendeger Margarete V.C.
Published: July 2023

O ensaio, mesmo quando expõe uma teoria, nunca o faz de maneira doutrinal e dogmática, pois não tem a pretensão de oferecer conteúdos acabados, limitando-se a coordenar ideias. Por essa razão, na história da literatura é comum encontrar escritores que dedicaram parte de seu tempo à escrita de ensaios com o objetivo de expressar seus pontos de vista sobre temas ligados ao campo literário. Entre esses escritores encontra-se Ernesto Sabato (1911-2011), que utilizou o ensaio para expor, de maneira clara, concisa e interessante, suas concepções sobre arte, literatura, criação de romances e o papel do escritor. Este artigo analisa, em um primeiro momento, os conceitos do autor argentino sobre a criação artística, para, depois, examinar sua “teoria do romance”, com o propósito de esboçar um amplo panorama das ideias do escritor sobre esses temas. Para fundamentar essa análise foram utilizados, além de parte da sua fortuna crítica, alguns dos ensaios escritos por Sabato, em especial aqueles reunidos na obra El escritor y sus fantasmas.
AIRA Y GERHARD RICHTER PATRULLAN EL PROCEDIMIENTO CRÍTICO
Authors: Corral Wilfrido H.
Published: July 2023

Entre 1996 y 2022 la preponderancia en la ficción latinoamericana de novelizar el arte pictórico, a los artistas y sus cavilaciones críticas ha engendrado interpretaciones interdisciplinarias. El voluble César Aira está al frente de esa práctica, discutiblemente como precursor de una nueva autobiograficción. Con atención a Walter Benjamin y al arte contemporáneo, es factible que, al comparar la historia del argentino con la de un artista igualmente volátil, el alemán Gerhard Richter, al codificar sus opiniones sobre el “realismo”, el arte no representativo y el papel de la crítica controlan la interpretación de su obra.

Published: July 2023

Este artigo tem como tema a vocalização do texto poético escrito concebida como uma experiência na linguagem, na particularidade do Projeto Invasão Cultural, uma proposta constituída por perfórmances poéticas vocalizadas em espaços escolares. A investigação busca refletir, a partir da análise de dizeres de dois participantes protagonistas da experiência, sobre os arranjos enunciativos decorrentes da vocalização, uma vez que, via mobilização da voz, novas significações se presentificam na particularidade do discurso poético. O trabalho se pauta na abordagem enunciativa benvenistiana e a concepção poética assumida se volta para os arranjos singulares e inusitados da língua-discurso. Os resultados mostram que a experiência de vocalização do texto poético evoca sentidos particulares vivenciados na historicidade do sujeito na linguagem e exerce importante papel na sua constituição.
Religion and the Protest Movement
Authors: Zakharov Nikolay , Lastouski Aliaksei , Mudrov Sergei
Published: July 2023

This article analyzes the position of the Christian churches on the protests in Belarus in 2020. This study contributes to the research on the state-society relationship in autocratic regimes by nuancing the thesis that civil society is either marginalized or fully co-opted by the authoritarian state. The protest wave showed that the initiatives of religious groups fostered collective action in a state system that is punitive of any dissent. The article identifies churches as an ambivalent space: one where the state can exercise social control, but where potential resistance to the repressive state might also occur since they enjoy a greater degree of freedom than other organizations in authoritarian Belarus. Moreover, our study argues that religion can be seen as a privileged arena of protest within existing legal frameworks of the “contract” between the state and the church. By looking at the societal engagement of different religious confessions campaigning for their rights and promoting their visions of desirable political development on the grassroots level, this article addresses a range of opportunities to engage in civic activism in Belarus.
ENGRAILED‐1 transcription factor has a paracrine neurotrophic activity on adult spinal α‐motoneurons

Published: July 2023

Several homeoprotein transcription factors transfer between cells and regulate gene expression, protein translation, and chromatin organization in recipient cells. ENGRAILED‐1 is one such homeoprotein expressed in spinal V1 interneurons that synapse on α‐motoneurons. Neutralizing extracellular ENGRAILED‐1 by expressing a secreted single‐chain antibody blocks its capture by spinal motoneurons resulting in α‐motoneuron loss and limb weakness. A similar but stronger phenotype is observed in the Engrailed‐1 heterozygote mouse, confirming that ENGRAILED‐1 exerts a paracrine neurotrophic activity on spinal cord α‐motoneurons. Intrathecal injection of ENGRAILED‐1 leads to its specific internalization by spinal motoneurons and has long‐lasting protective effects against neurodegeneration and weakness. Midbrain dopaminergic neurons express Engrailed‐1 and, similarly to spinal cord α‐motoneurons, degenerate in the heterozygote. We identify genes expressed in spinal cord motoneurons whose expression changes in mouse Engrailed‐1 heterozygote midbrain neurons. Among these, p62/SQSTM1 shows increased expression during aging in spinal cord motoneurons in the Engrailed‐1 heterozygote and upon extracellular ENGRAILED‐1 neutralization. We conclude that ENGRAILED‐1 might regulate motoneuron aging and has non‐cell‐autonomous neurotrophic activity.

Published: July 2023

Research on the relationship between GRDP and income inequality shows that there is a spatial autocorrelation, however, empirical data shows that there is still income inequality that differs between regions, so it is necessary to re-examine the relationship. The island of Java is the main pillar of Indonesia's economic cycle, but the income inequality between the provinces is still high. This study aims to identify the magnitude of income inequality in Java. Identify the autocorrelation of GRDP and income inequality spatially, and in clusters and identify the causal relationship between GRDP and income inequality in Java. The analysis method uses the Williamson Index, Moran Index, Local Indicator of Spatial Autocorrelation (LISA) using the LISA Clustermap, and Granger Quality. This study is on the level of income inequality in each province in Java based on the Williamson Index value in the category of high inequality, having a negative autocorrelation value (the pattern tends to spread) and there is no spatial autocorrelation. Autocorrelation based on LISA Clustermap there is a pattern of cluster linkages (clustering and influencing each other) which has a High-Spot value so that there are areas that can be used as areas of cooperation for development.

The number of Free Trade Agreements (FTA) based on each region or so called as Regional Trade Agreements (RTA) has been increased rapidly after the World Trade Organization (WTO) continues to increase from year to year. This cause of international trade are becoming autonomous. The Indonesia's participation at the ASEAN-India Free Trade Agreement (AIFTA)greatly affect to the economy due to strategic trade partnership which tied between Indonesia and India. This research has intention to explore more relates to impact of trade creation and trade diversion from the implementation of AIFTA on Indonesia's exports and imports through aggregate and disaggregated data which consisting of 6 commodities. The sample used in this research are consisted of 25 countries during year of 2006-2017. Poisson Pseudo Maximum Likelihood (PPML) were applied as estimation method. With estimation results shows that the implementation of AIFTA has significantly negative affect towards the export trade diversion. This indicates that there is a decline occurs in Indonesia's exports to non-AIFTA member countries. In disaggregated data, net trade creation is found in food-drinks,tobacco and livestock, energy products also raw materials. Furthermore, this net trade diversion were also found in other manufactured goods and machinery and transport equipment.
Assessing treatment adherence is crucial to determine adequacy of mineralocorticoid therapy

Published: July 2023

Background

There is no consensus strategy for mineralocorticoid (MC) therapy titration in patients with primary adrenal insufficiency (PAI). We aim to measure serum fludrocortisone (sFC) and urine fludrocortisone (uFC) levels and to determine their utility, alongside clinical/biochemical variables and treatment adherence to guide MC replacement dose titration.

Methods

Multi-centre, observational, cross-sectional study on 41 patients with PAI on MC replacement therapy. sFC and uFC levels (measured by liquid chromatography-tandem mass spectrometry), plasma renin concentration (PRC), electrolytes (Na+, K+), mean arterial blood pressure (MAP), total daily glucocorticoid (dGC) and MC (dMC) dose, and assessment of treatment adherence were incorporated into statistical models.

Results

We observed a close relationship between sFC and uFC (r = 0.434, P = 0.005) and between sFC and the time from the last fludrocortisone dose (r = −0.355, P = 0.023). Total dMC dose was related to dGC dose (r = 0.556, P < 0.001), K+ (r = −0.388, P = 0.013) as well as sFC (r = 0.356, P = 0.022) and uFC (r = 0.531, P < 0.001). PRC was related to Na+ (r = 0.517, P < 0.001) and MAP (r = −0.427, P = 0.006), but not to MC dose, sFC or uFC. Regression analyses did not support a role for sFC, uFC or PRC measurements and confirmed K+ (B = −44.593, P = 0.005) as the most important variable to guide dMC titration. Of the patients, 32% were non-adherent with replacement therapy. When adherence was inserted into the regression model, it was the only factor affecting dMC.

Conclusions

sFC and uFC levels are not helpful in guiding dMC titration. Treatment adherence impacts on clinical variables used to assess MC replacement and should be included as part of routine care in patients with PAI.
Lymphangioleiomyomatosis: where endocrinology, immunology and tumor biology meet
Authors: Gibbons Erin , Minor Briaunna M N , Hammes Stephen R
Published: July 2023

Graphical abstract

Lymphangioleiomyomatosis (LAM) is a cystic lung disease found almost exclusively in genetic females and caused by small clusters of smooth muscle cell tumors containing mutations in one of the two tuberous sclerosis genes (TSC1 or TSC2). Significant advances over the past 2–3 decades have allowed researchers and clinicians to more clearly understand the pathophysiology of LAM, and therefore better diagnose and treat patients with this disease. Despite substantial progress, only one proven treatment for LAM is used in practice: mechanistic target of rapamycin complex 1 (mTORC1) inhibition with medications such as sirolimus. While mTORC1 inhibition effectively slows LAM progression in many patients, it is not curative, is not effective in all patients, and can be associated with significant side effects. Furthermore, the presence of established and accurate biomarkers to follow LAM progression is limited. That said, discovering additional diagnostic and treatment options for LAM is paramount. This review will describe recent advances in LAM research, centering on the origin and nature of the LAM cell, the role of estrogen in LAM progression, the significance of melanocytic marker expression in LAM cells, and the potential roles of the microenvironment in promoting LAM tumor growth. By appreciating these processes in more detail, researchers and caregivers may be afforded novel approaches to aid in the treatment of patients with LAM.
Electroless nickel deposition on Fraxinum mandshurica veneer modified with APTHS for EMI shielding
Authors: Liu Haibing , Wang Lijuan
Published: July 2023

Electroless nickel deposition was carried out on Fraxinus mandshurica veneers for EMI shielding under a new activation process. In the process, Pd(II) was ed on the surface of veneers modified with γ-aminopropyltrihydroxysilane (APTHS) obtained from the hydrolysis of γ-aminopropyltriethoxysilane (APTES). After the reduction, electroless plating was successfully initiated, and Ni-P coating was deposited on the veneers. The activation process and resulting coating were characterized by XPS, SEM-EDS, and XRD. The metal deposition, surface , and electromagnetic shielding effectiveness were measured. XPS analysis proved that Pd(II) was bonded to the amino group of APTHS and reduced to Pd(0). The coating was continuous, uniform, and compact. It consisted of 97.4 wt% nickel and 2.6 wt% phosphorus. XRD analysis showed that the coating was crystalline, which was related to the low phosphorus content. The plated Fraxinus mandshurica veneers exhibit good electro-conductivity with surface resistivity of 0.21Ω·cm-2 and higher electromagnetic shielding effectiveness of over 50dB in frequencies from 10 MHz to 1.5 GHz.
Characterization of key parameters for biotechnological lignocellulose conversion assessed by FT-NIR spectroscopy. Part 1. Qualitative analysis of pretreated straw
Authors: Krongtaew Chularat , Messner Kurt , Ters Thomas , Fackler Karin
Published: July 2023

Wheat straw (Triticum aestivum L.) and oat straw (Avena sativa L.) were subjected to acid and alkaline pre-treatments partly in combination with hydrogen peroxide. The aim was to remove lignin and increase the accessibility of the polysaccharides to enzymatic digestion. Accessibility was evaluated by digestion with a cell wall degrading enzyme complex to yield reducing sugars that may serve as precursor substrates for biofuels or building block chemicals. Changes in lignin, hemicelluloses, as well as amorphous, semi-crystalline, and crystalline regions of cellulose moieties of pretreated straw were efficiently characterized by Fourier transform near-infrared (FT-NIR) reflectance spectroscopy. These alterations of the chemical structure of straw after different pre-treatment methods were powerfully differentiated by principal component analysis (PCA). Characteristics of the different samples owing to the different pre-treatment methods could be clustered from the PCA loadings spectra.

The present study aimed at producing high yield pulp and the best mechanical strength properties with minimum impact on environment by SAS-AQ, and NSSC-AQ pulping processes. A total alkali of 13% (as Na2O), an alkali ratio of 0.80, and a Na2SO3 charge 11.70% (as Na2O) were found optimum to reduce maximum kappa number. A lower kappa number and good strength properties were achieved by increasing total alkali and Na2SO3 charge. SAS-AQ pulps showed good response towards CEHH bleaching. The NSSC-AQ pulping was conducted at a total alkali charge of 8% (as Na2O) by varying the ratio of sulphite-to-carbonate (100:0-0:100), and cooking time (60-120 min) at 1600C. A ratio of sulphite-to-carbonate 60:40 was suitable for corrugating medium (cooking time 60 min), while a ratio of sulphite-to-carbonate 70:30 showed better strength properties (longer cooking time).

The peroxymonocarbonate mono-anion (HCO4─) is generated when the bicarbonate anion is added to a H2O2 solution. The mono-anion is believed to have a pKa value of ca. 10 and as such would start dissociating to the di-anion (CO42─) at pH ca. 8. The mono-anion should demonstrate electrophilic properties, while the di-anion should be a nucleophile. In an alkaline, non-sulfur pulping process such as soda/AQ, Na2CO3 could be obtained from the chemical recovery system and carbonated with CO2 from a flue gas stream to produce NaHCO3. In such a case only H2O2 would need to be purchased to generate the peroxymonocarbonate (PMC) anions. Bicarbonate anions could also be produced from the carbonation of solutions containing NaOH, Mg(OH)2 or mined Na2CO3. One or both of the PMC anions was found to be effective in oxidizing two lignin model compounds as well as lowering the lignin content of kraft and soda/AQ hardwood pulps. The PMC anions were generated in-situ by NaHCO3 or Na2CO3 + CO2 addition to dilute H2O2 solutions.

Authors: Jia Boyang , Wang Lijuan
Published: July 2023

Nickel-based activated carbon was prepared from coconut shell activated carbon by electroless plating with palladium-free activation. The materials were characterized by scanning electron microscopy (SEM), X-ray energy dispersion spectroscopy (EDS), vibrating sample magnetometry (VSM), and vector network analyzer, respectively. The results show that the surface of the activated carbon was covered by a Ni-P coating, which was uniform, compact, and continuous and had an obvious metallic sheen. The content of P and Ni was 2.73% and 97.27% in the coating. Compared with the untreated activated carbon, the real permeability μ′ and imaginary permeability μ″ of Ni-based activated carbon became greater, whereas the real permittivity ε′ and imaginary permittivity ε″ became smaller. Also, the plated activated carbon was magnetic, making it suitable for some special applications. In general, the method reported here might be a feasible procedure to coat activated carbon with other magnetic metals, which may find application in various areas.
Actualization. Sexual abuse, imprinting, and Tourette’s syndrome. Protagonist, deuteragonist, tritagonist, and hybris
Authors: Cuevas-Sosa Alejandro
Published: July 2023

I propose the examination of imprinting resulting from sexual abuse as a potential factor that may influence various outcomes, including homosexuality, stuttering, and autism in both men and women. It is suggested that imprinting originally triggered by sexual abuse might contribute to the development of these conditions. One possible sequence, among others, could involve the following: Sexual abuse imprinting (leading to imprinting of homosexuality) may be associated with imprinting of stuttering and autism in both men and women. These conditions, observed with an average ratio of four men to one woman, are known to be challenging to modify. These collective observations give rise to the imprinting syndrome of sexual abuse. The purpose of the first part of this update opinion article is to expand both the references and the information that supports it by including Tourette's syndrome as another possible consequence of child sexual abuse. For more information on the background and procedures used, it is suggested to read reference 22. Through bioenergemal communication, we establish interaction with human bioenergemes (BEGs) that arrive at the bioenergemal (BEL) universe after people biocollapse (die). This BEL information does not intend to ratify or rectify the official version of these facts; it only presents the bioinformation that some BEGs shared with us.

The publication highlights some technical issues related to the design of equipment for monitoring the distribution of plastic waste on sea beaches, in particular within the surf zones. Sample selection procedures, alternative to the existing ones, were considered, and certain methods and technical means were proposed to optimize the sampling process. The expediency of creating traps for macro- and microplastics, the long-term continuous use of which can open new methodological approaches to regular observations of these pollutants, is substantiated. Such field observations combined with the recording of hydrometeorological data (winds, currents, and dynamics of wave activity) will allow to determine the intensity of the introduction of plastic material from certain geographical locations and to investigate probable sources of input depending on the characteristics of its composition.
Operator Formulation for Centered Optical Systems
Authors: Demydenko I.V.
Published: July 2023

Currently, there are many mathematical methods in use in geometric optics. This paper presents a new mathematical apparatus: an operator formalism, which describes centered optical systems in the paraxial approximation. This work is an ideological continuation of author’s previous research. The refraction and reflection operators of spherical surfaces are defined here. The mathematical properties of the operators are studied, and their physical interpretations are established. In addition, the relations between the lensing operator and the refraction operators of a spherical surface are determined. The behavior of rays is also considered, which helped to establish the injectivity and nondegeneracy for points with infinite coordinates. The operator formalism is helpful for finding a centered optical system that performs a given transformation. Moreover, the interchangeability of the optical operators is investigated, and it is found that each operator has a unique effect.

O objetivo é observar a Lei nº 12.990/2014, analisando os municípios de Pelotas e Rio Grande no Rio Grande do Sul. Ao levantar a base teórica que discute as ações afirmativas no Brasil, surgiram questionamentos, principalmente sobre a Lei nº 12.990/2014 e seus reflexos na aplicação na esfera municipal. Contudo, ainda que ocorra alusão às legislações já existentes, foram observadas lacunas e discussões equivocadas nos editais que datam até o ano de análise, 2019. Entende-se que a participação dos negros e negras nos órgãos públicos visa possibilitar não só a mobilidade social e quebra do padrão hegemônico branco de manutenção do poder, mas, sobretudo, uma forma de desenvolver um letramento racial crítico visando atingir o campo da reflexão e da ação de todos os servidores públicos.

O presente trabalho relata a formação de professores da Educação Básica com o aprofundamento da metodologia de Experimentação Investigativa no Ensino de Ciências durante a Pandemia que causou a Covid-19 por infecção pelo coronavírus SARS-CoV-2. O artigo tem por objetivo analisar os Experimentos Investigativos elaborados durante a formação continuada de professores no formato de minicurso online, com a duração de duas semanas, em encontros síncronos e assíncronos. Nos encontros síncronos foram abordados os aspectos epistemológicos e pedagógicos da Experimentação Investigativa e os exemplares de Experimentos Investigativos. Após, os professores elaboraram atividades investigativas que podem ser implementadas em seus contextos de aulas remotas. Os experimentos foram analisados a partir de categorias a priori, sendo elas: (1) Natureza: teórico x prático ou laboratório virtual; (2) Experimentos de natureza Disciplinares ou interdisciplinares; (3) Nível de ensino que abrangem os experimentos; (4) Forma de resolução; (5) Tipos de questões levantadas pelo professor a partir do experimento; (6) Relatório a partir dos Experimentos Investigativos. Essa experiência sinalizou que os experimentos elaborados durante o curso de formação têm natureza teórico-prática, pouco são interdisciplinares, foram elaborados para o Ensino Fundamental e Médio. No Ensino Fundamental sugerem a elaboração de vídeos para socialização dos conhecimentos a elaboração de relatório e vídeo conferência, com o objetivo de socializar os resultados dos experimentos investigativos.

¿Cómo se promueve la competencia matemática en los libros de texto de educación infantil?: un análisis de la demanda cognitiva
Authors: Vásquez Claudia , Pincheira Nataly , Alsina Ángel
Published: July 2023

En este trabajo se presenta el análisis de las tareas matemáticas presentes en libros de texto chilenos para la educación infantil. Para ello, hemos optado por un enfoque cualitativo de carácter descriptivo utilizando como método de investigación la técnica de análisis de contenido para analizar y describir la demanda cognitiva de las tareas matemáticas propuestas en los libros de texto. Nos centramos en la demanda cognitiva de las tareas matemáticas propuestas, puesto que gran parte del aprendizaje está condicionado por el tipo de tareas que se plantean a los niños, por tanto, es un elemento clave para favorecer el desarrollo de la competencia matemática desde edades tempranas. Los resultados muestran la presencia de tareas vinculadas a la memorización y a procedimientos con conexión. De ello se desprende que  es necesario que el profesorado cuente con los conocimientos disciplinares y didácticos que le permitan enriquecer las tareas que se presentan en los libros de texto para favorecer que los niños, a través del andamiaje colectivo, coconstruyan y reconstruyan nuevos conocimientos y desarrollen gradualmente la competencia matemática.
