Authors: Fauzah Zafira , Wafiqoh Risnina , Hevitria Hevitria
Published: March 2024

This research is driven by the low of student’s critical thinking ability in learning Mathematics as well as teachers that still use conventional models during teaching and learning activities. This research aims to determine the effect of the Means Ends Analysis (MEA) learning model on students' critical thinking ability. The quasi-experimental method is used in this research along with a quantitative approach. The research design uses a non-equivalent control group pre-test post-test design. This research applied the MEA learning model to the experimental class and the conventional model to the control class. The population in this study was the fifth-grade students at one of the Pangkalpinang State Elementary Schools. Purposive sampling is used as the sampling technique. The samples in this research were Class V-A as the experimental and Class V-B as the control class. The data collection technique uses a critical thinking ability test in the form of essay questions consisting of a pre-test and a post-test. The data analysis technique in this research uses the normality test (Kolmogorov Smirnov test), homogeneity test (Fisher test), and hypothesis test which uses the dependent sample t-test (pooled variance). Based on the results of the hypothesis test using the dependent sample t-test (pooled variance), the value of tcount = 5,185 > ttable = 1,995. So, it can be concluded that Ha is accepted; it means that there is an influence of the MEA learning model on students' critical thinking ability in class V on fraction topic.
Net Zero Carbon Emission
Authors: Jathot Harshad
Published: March 2024

Abstract: With the rapid growth of digital services and the increasing reliance on data centers, energy consumption and carbon emissions from server infrastructure have become significant environmental concerns. This abstract outlines a novel approach for carbon detection from servers, aiming to improve the sustainability of data centers. Carbon emissions from data centers are increasingly a cause for concern, as the world grapples with the realities of climate change. According to recent studies, data centers are responsible for a significant share of global electricity consumption, and subsequently, carbon emissions. It’s evident that addressing the sustainability of data centers is not just a technological challenge; it’s a moral and environmental imperative.

Published: March 2024

O texto apresenta reflexões acerca do relato de experiência do II Seminário de Extensão “Pensadores Sociais e o Esporte no Cinema”, realizado no âmbito do curso de formação de professores de Educação Física da Universidade Federal de Sergipe, no ano de 2023. Nesse seminário propusemos interpelar o esporte sob as lentes do cinema problematizando questões sociais emergentes na contemporaneidade. Foram indicados os conceitos de: espetáculo, por Guy Debord; fascismo, por Umberto Eco; imunidade, por Roberto Esposito; estigma, por Erving Goffman; e drama social, de Roberto DaMatta. Esses conceitos foram analisados em diálogos, respectivamente, com os filmes Rollerball – os gladiadores do futuro (1975), A Onda (2009), Raça (2016), Tá dando onda (2007) e Boleiros – era uma vez o futebol… (1998). Concluímos que o diálogo com o cinema na formação de professores permite-nos compreender que a dinâmica social do presente, com o avanço de discursos e práticas autoritárias, de preconceitos sociais, de banalização de nossas desigualdades, precisa ser problematizada e combatida na raiz de suas problemáticas.

obsceno contra e pela democracia:
Authors: Oliveira Veiga Roberta , de Carvalho Penido Fábio
Published: March 2024

Dois escândalos midiáticos de impacto para a frágil democracia brasileira, o Kit Gay e o Golden Shower, são retomados no sentido de refletir sobre os diferentes modos como Jair Bolsonaro e sua equipe se apropriaram de imagens obscenas para naturalizar sua ficção política. Na narrativa da extrema-direita, o obsceno é um instrumento de reestabelecimento da ordem conservadora que, através de dispositivos audiovisuais, instiga o pânico moral e a guerra cultural como pilar ideológico. Diante dos mesmos escândalos, um olhar dissidente à proliferação de imagens bolsonaristas pode deslocar essa noção de seu léxico moralizador para diversas formas de alteridade e subjetivação política, como o uso da pós-pornografia e da dimensão abjeta dos corpos pelas experime ntações performáticas e cinematográficas LGBTQIA+.
Sentidos produzidos sobre Clarice Lispector em podcasts
Authors: Scorsolini-Comin Fabio , Rodrigues Loise Ishikawa , Pacífico Soraya Maria Romano
Published: March 2024

O objetivo deste estudo é conhecer os principais sentidos sobre Clarice Lispector produzidos em podcasts. Foram analisados quatro podcasts, totalizando 17 episódios produzidos no ano de 2020 em comemoração ao centenário de nascimento da autora. Os podcasts analisados representam a celebração de Clarice como figura da nossa literatura, definindo-a como figura excêntrica, genial, capaz de apresentar várias faces e de surpreender permanentemente os seus leitores. As análises de suas obras são apresentadas ancoradas na vida da autora, sem que um processo mais crítico em relação ao conceito de autoria seja compartilhado. Clarice é representada como uma autora ainda em movimento, o que vem sendo fomentado, por exemplo, pelo modo como Clarice tem circulado nas malhas do digital, o que põe em destaque fortemente os podcasts. O podcast torna-se, por excelência, um veículo capaz de evidenciar a escuta de Clarice, produzindo, ao mesmo tempo, leitores e ouvintes que promovem a circulação da autora e de seus escritos em um espaço que não é o livro tradicional, mas uma mídia na qual a palavra deve ser escutada, em um importante processo de percepção sensorial.
Uma perspectiva feminina sobre traduzir Xenofonte no Brasil de hoje
Authors: Sano Lucia
Published: March 2024

O texto discute minha trajetória como pesquisadora de literatura grega antiga, da qual resulta a tradução de duas obras de Xenofonte de Atenas usualmente consideradas historiográficas: Ciropédia (2021) e Anábase (publicação prevista em 2024). Procuro refletir sobre como minha relação com a tradução dos clássicos se definiu (e se alterou) a partir do contexto mais amplo dos Estudos Clássicos no Brasil no século XXI, considerando-se, entre outros fatores, a expansão da nossa área de pesquisa no país resultante de políticas públicas; as condições de trabalho no campo acadêmico e a ascensão do pensamento conservador e extremista no país nos últimos anos.
A tradução da comédia aristofânica: reescrita de resistência à tradição
Authors: Sansone Bosco Giglio Stefania
Published: March 2024

Este artigo busca fazer uma análise comparativa de duas traduções da peça Acarnenses, de Aristófanes, realizadas por SILVA (1988) e POMPEU (2021), examinando ações estratégicas de tradução do texto cômico para a língua portuguesa, como resultado de uma prática ideológico-discursiva em seus contextos de tradução.  Entende-se a tradução como um processo de reescrita (LEFEVERE, 2007) que dialoga não só com a Teoria dos Polissistemas (EVEN-ZOHAR, 1979) mas também com uma releitura de “resistência” (VENUTI, 2002) para pensar os processos de estrangeirização e domesticação em um tipo de composição considerado menor. Procura-se defender que o processo de domesticação faz parte de um grito de resistência, a fim de propor novas formas de considerar a comédia aristofânica em traduções no Brasil, situada à margem do que é considerado clássico ou canônico, como construção de um discurso dissidente.

Parásitos en la salud pública
Authors: Hernandez Arenas Diana Paola
Published: March 2024

La parasitología, estudia la relación existente entre los organismos parásitos y sus huéspedes, pudiendo o no causar daños a su hospedador. Al igual que los parásitos, los sistemas de producción se desarrollan en un medio físico, biológico y social; y es en este último en donde suele influir de manera significativa para la salud pública de las regiones y poblaciones consolidándose como un factor importante en la presentación de enfermedades zoonóticas parasitarias y por ende causal del detrimento sanitario de las poblaciones que se ven afectadas. Por ello, la parasitología tomada desde el punto de vista de la salud pública, proporciona herramientas que permiten conocer y fortalecer la prevención y el control de los agentes parasitarios que afectan la población humana y animal debido a su carácter zoonótico, ayudando a reducir el impacto que ocasionan dichas zoonosis parasitarias en la salud pública; Sin embargo, es poco frecuente hallar bibliografía actualizada que logre demostrarlo claramente. Teniendo en cuenta lo anterior, la parasitología se instaura dentro del proceso académico de los estudiantes de Zootecnia como un eje encaminado a la comprensión no solo del ciclo de vida del parasito, sino también de las consecuencias que pueden traer para las explotaciones productivas y la población, por tanto, la presente nota de campus tiene como finalidad dar a conocer al estudiante las generalidades de las zoonosis vistas desde la salud pública, dando a conocer algunos aspectos concernientes con el impacto de la parasitología en esta, así como algunos de los parásitos zoonóticos más frecuentes. Inicialmente, se presenta el concepto de zoonosis parasitarias, los factores asociados a su transmisión y otros conceptos fundamentales que enmarca la temática, la cual se desglosa en cada uno de los capítulos que incluye el documento. Dicho contenido que puede ser usado como apoyo en el curso de Parasitología, el cual hace parte del componente disciplinar de la malla curricular de los programas de Zootecnia y Tecnología en Producción Animal.
Probabilistic petrophysical reconstruction of Danta's Alpine peatland via electromagnetic induction data
Authors: Zaru N , Silvestri S , Assiri M , Bai P , Hansen T M , Vignoli Giulio
Published: March 2024

Peatlands are fundamental deposits of organic carbon. Thus, their
protection is of crucial importance to avoid emissions from their
degradation. Peat is a mixture of organic soil that originates from the
accumulation of wetland plants under continuous or cyclical anaerobic
conditions for long periods. Hence, a precise quantiﬁcation of peat
deposits is extremely important; for that, remote- and proximal-sensing
techniques are excellent candidates. Unfortunately, remote-sensing can
provide information only on the few shallowest centimeters, whereas
peatlands often extend to several meters in depth. In addition,
peatlands are usually characterized by difficult (flooded) terrains. So,
frequency-domain electromagnetic instruments, as they are compact and
contactless, seem to be the ideal solution for the quantitative
assessment of the extension and geometry of peatlands. Generally,
electromagnetic methods are used to infer the electrical resistivity of
the subsurface. In turn, the resistivity distribution can, in principle,
be interpreted to infer the morphology of the peatland. Here, to some
extent, we show how to shortcut the process and include the expectation
and uncertainty regarding the peat resistivity directly into a
probabilistic inversion workflow. The present approach allows for
retrieving what really matters: the spatial distribution of the
probability of peat occurrence, rather than the mere electrical
resistivity. To evaluate the efficiency and effectiveness of the
proposed probabilistic approach, we compare the outcomes against the
more traditional deterministic fully nonlinear (Occam’s) inversion and
against some boreholes available in the investigated area.
A new method for the detection of siliceous microfossils on sediment microscope slides using convolutional neural networks

Published: March 2024

Diatom communities preserved in sediment samples are valuable indicators
for understanding the past and present dynamics of phytoplankton
communities, and their response to environmental changes. These studies
are traditionally achieved by counting methods using optical microscopy,
a time-consuming process that requires taxonomic expertise. With the
advent of automated image acquisition workflows, large image datasets
can now be acquired, but require efficient preprocessing methods.
Detecting diatom frustules on microscope images is a challenge due to
their low relief, diverse shapes, and tendency to aggregate, which
prevent the use of traditional thresholding techniques. Deep learning
algorithms have the potential to resolve these challenges, more
particularly for the task of object detection. Here we explore the use
of a Faster R-CNN (Region-based Convolutional Neural Network) model to
detect siliceous biominerals, including diatoms, in microscope images of
a sediment trap series from the Mediterranean Sea. Our workflow
demonstrates promising results, achieving a precision score of 0.72 and
a recall score of 0.74 when applied to a test set of Mediterranean
diatom images. Our model performance decreases when used to detect
fragments of these microfossils; it also decreases when particles are
aggregated or when images are out of focus. Microfossil detection
remains high when the model is used on a microscope image set of
sediments from a different oceanic basin, demonstrating its potential
for application in a wide range of contemporary and paleoenvironmental
studies. This automated method provides a valuable tool for analysing
complex samples, particularly for rare species under-represented in
training datasets.
Quantifying Regional Efficiency of Marine Carbon Dioxide Removal (mCDR) via Alkalinity Enhancement using the ECCO-Darwin Ocean Biogeochemistry State Estimate and an Idealized Vertical 1-D Model
Authors: Suselj Kay , Carroll Dustin , Menemenlis Dimitris , Zhang Hong , Beatty Nate , Savage Anna , Whitt Daniel Bridger
Published: March 2024

As a marine Carbon Dioxide Removal (mCDR) approach, Ocean Alkalinity
Enhancement (OAE) is emerging as a viable method for removing
anthropogenic CO2 emissions from the atmosphere to mitigate climate
change. To achieve substantial carbon reduction using this method, OAE
would need to be widespread and scaled-up across the global ocean.
However, the efficiency of OAE varies substantially across a range of
space-time scales and as such field deployments must be carefully
planned to maximize efficiency and minimize logistical costs and risks.
Here we develop a mCDR efficiency framework based on the
data-assimilative ECCO-Darwin ocean biogeochemistry model, which
examines two key factors over seasonal to multi-decadal timescales: 1)
mCDR potential, which quantifies the CO2 solubility of the upper ocean;
and 2) dynamical mCDR efficiency, representing the full-depth impact of
ocean advection, mixing, and air-sea CO2 exchange. To isolate and
quantify the factors that determine dynamical efficiency, we develop a
reduced complexity 1-D model, rapid-mCDR, as a computationally-efficient
tool for evaluation of mCDR efficiency. Combining the rapid-mCDR model
with ECCO-Darwin allows for rapid characterization of OAE efficiency at
any location globally. This research contributes to our understanding
and optimization of OAE deployments (i.e., deploying experiments in the
real-world ocean) as an effective mCDR strategy and elucidates the
regional differences and mechanistic processes that impact mCDR
efficiency. The modeling tools developed in this study can be readily
employed by research teams and industry to plan and complement future
field deployments and provide essential Monitoring, Reporting, and
Verification (MRV).

When the velocity shear between the two plasmas separated by Earth’s
magnetopause is locally super-Alfvénic, the Kelvin-Helmholtz (KH)
instability can develop. A crucial role is played by the interplanetary
magnetic field (IMF) orientation, which can stabilize the velocity
shear. Although, in a linear regime, the instability threshold is
equally satisfied during both northward and southward IMF orientations,
in-situ measurements show that KH instability is preferentially excited
during the northward IMF orientation. We investigate this different
behavior by means of a mixing parameter which we apply to two KH events
to identify both boundaries and the center of waves/vortices. During the
northward orientation, the waves/vortex boundaries have stronger
electrons than ions mixing, while the opposite is observed at their
center. During the southward orientation, instead, particle mixing is
observed predominantly at the boundaries. In addition, stronger local
ion and electron non-thermal features are observed during the northward
than the southward IMF orientation. Specifically, ion distribution
functions are more distorted, due to field-aligned beams, and electrons
have a larger temperature anisotropy during the northward than the
southward IMF orientation. The observed kinetic features provide an
insight into both local and remote processes that affect the evolution
of KH structures.
Rift zone architecture and inflation-driven seismicity of Mauna Loa volcano
Authors: Wilding John D. , Ross Zachary E.

The 2022 eruption at Mauna Loa, Hawai‘i, marked the first extrusive
activity from the volcano after 38 years of quiescence. The eruption was
preceded by several years of seismic unrest in the vicinity of the
volcano’s summit. Characterizing the structure and dynamics of
seismogenic features within Mauna Loa during this pre-eruptive interval
may provide insights into how pre- and co-eruptive processes manifest
seismically at the volcano. In particular, the extent to which
seismicity may be used to forecast the location and timing of future
eruptions is unclear. To address these questions, we construct a catalog
of relocated seismicity on Mauna Loa spanning 2011-2023. Our earthquake
locations image complex, sub-kilometer-scale seismogenic structures in
the caldera and southwest rift zone. We additionally identify a set of
streaks of seismicity in the volcano’s northwest flank that are radially
oriented about the summit. Using a rate-and-state friction model for
earthquake occurrences, we demonstrate that the seismicity rate in this
region can be modeled as a function of the stressing history caused by
magma accumulation beneath the summit. Finally, we observe a mid-2019
step change in the seismicity rate in the Ka‘oiki region that may have
altered the stress state of the northeast rift zone in the three years
before the eruption. Our observations provide a framework for
interpreting future seismic unrest at Mauna Loa.

Autoantibodies to glutamate decarboxylase (GADA) are widely used in the prediction and classification of type 1 diabetes. GADA radiobinding assays (RBAs) using N-terminally truncated antigens offer improved specificity but radioisotopes limit the high-throughput potential for population screening. Luciferase-based Immunoprecipitation System (LIPS) assays are sensitive and specific alternatives to RBAs with the potential to improve risk stratification. The performance of assays using the Luciferase (Nluc-) conjugated GAD65 constructs, Nluc-GAD65(96-585) and full length Nluc-GAD65(1-585) were evaluated in 434 well-characterised sera from recent-onset type 1 diabetes patients and first-degree relatives. Non-radioactive, high-throughput LIPS assays are quicker and require less serum than RBAs. Of 171 relatives previously tested single autoantibody positive for autoantibodies to full-length GAD65 by RBA but had not progressed to diabetes, fewer retested positive by LIPS using either truncated (n=72) or full-length (n=111) antigen. The Nluc-GAD65(96-585) truncation demonstrated the highest specificity in LIPS assays overall but in contrast to RBA, N-terminus truncations did not result in a significant increase in disease-specificity compared with the full-length antigen. This suggests that binding of non-specific antibodies is affected by the conformational changes resulting from addition of the Nluc antigen. Nluc-GAD65(96-585) LIPS assays offer low blood volume, high specificity GADA tests for screening and diagnostics.

El uso de medicamentos con condición de venta con fórmula médica sin contar con la prescripción es una práctica que se ha denominado “auto prescripción” y que puede traer riesgos para la salud de las personas, al Utilizar medicamentos que no se necesitan o que no estarían indicados para las condiciones de salud de un paciente en particular. Con el fin de evaluar el aporte a las prácticas de auto prescripción por parte de los establecimientos farmacéuticos minoristas (droguerías) de la localidad de Chapinero Bogotá D.C. Colombia durante el año 2022, se realizó un estudio descriptivo y de corte transversal, por medio de simulación de compra realizada a través de entrevista presencial en 65 droguerías seleccionadas, en donde se realizaron 155 simulaciones con 11 casos diferentes que incluyen medicamentos como azitromicina, metoclopramida, Anticonceptivos orales, complejo b y diclofenaco inyectables, bisacodilo, sildenafil, misoprostol, amitriptilina, dihidrocodeína, tramadol, difenoxilato y atropina. Se encuentra que en el 81.9% de las simulaciones se accedió a la venta del medicamento sin la presentación de la fórmula médica y en el 22% de los casos se recomendó usar otro medicamento diferente para sustituir o complementar el medicamento solicitado. En las droguerías de la localidad de Chapinero estudiadas se restringió la venta de medicamentos a la presentación de la fórmula médica en el 18.1% de las simulaciones realizadas. Los medicamentos en los cuales se encontró más restricción para su venta fueron misoprostol, azitromicina y tramadol.

Published: March 2024

When a patient is interrupted by velopharyngeal closure or defects in the hard palate, air escapes inappropriately through the nose in nasal speech sounds. The obturator prosthesis with extension to the oropharynx is currently the best indication for maxillary defects, but it also represents a challenge for manufacturing and oral adaptation. The aim of this study was to report a clinical case of successful prosthetic rehabilitation of a 65-year-old woman who presented with a defect in the maxilla, soft palate, tonsil, and oropharynx after treatment for polymorphous low-grade adenocarcinoma. With her considerable loss of structure and tissue, she reported difficulties with impaired functions such as chewing, swallowing, and speaking and difficulty interacting with people. The oral rehabilitation was performed with an oropharyngeal obturator prosthesis with an extension to the oropharynx and a total mandibular denture. This case demonstrates that the rehabilitation with an oropharyngeal obturator prosthesis with an extension to the oropharynx and a total mandibular denture provides speech, chewing, and phonetics, directly interfering with her social life in the mutilated patient.

Background: Transurethral Resection of the Prostate (TURP) is the gold standard for surgical treatment of benign prostate hyperplasia (BPH). One of the postoperative complications of TURP is urinary tract infection (UTI). Symptomatic UTI occur despite preoperative sterile urine, prophylactic antibiotics and a closed drainage system. We studied the incidence of such symptomatic UTI and the microbial pattern observed.
Material and Methods: This was a prospective study of 220 patients who had monopolar TURP in our centre from 2015 to 2020. All patients had sterile urine before surgery. Catheters were removed three days postoperatively. Patients presenting with symptoms of UTI were subjected to urine culture and antibiotic sensitivity. The recorded variables include patient demographics, co-morbid factors; Diabetes, hypertension, presence or absence of preoperative catheterization, duration of surgery, presence of postoperative UTI, microbial patterns and antibiotic sensitivity patterns.
Results: The mean age of the patient was 66.25 years. 35.5% had preoperative catheterization. 42 (19%) patients were established to have symptomatic UTI. Age ≥ 65 years, duration of surgery ≥60 mins led to higher infection rates but preoperative catheterization, diabetes and hypertension did not influence UTI rates. The commonest organism was E. Coli and the most common sensitive antibiotic was levofloxacin (quinolone).
Conclusions: Symptomatic UTI post-TURP still occurs despite preoperative sterile urine and routine prophylactic antibiotics.
