Published: May 2024

Aim: To compare composite adverse perinatal outcomes (CAPO) in women with early- and late-onset intrahepatic cholestasis of pregnancy (ICP).
Materials and Methods: This study was designed as a single-center, retrospective study in a tertiary hospital and included a total of 198 patients with ICP, including 36 patients with early-onset ICP (EO-ICP) and 162 patients with late-onset ICP (LO-ICP). ICP that developed before the 28th week of gestation was defined as EO-ICP, and ICP that occurred after the 28th week of gestation was defined as LO-ICP. The existence of at least one of the following criteria was defined as CAPO: umbilical cord arterial pH < 7.20, fifth-minute Apgar score < 5, and neonatal intensive care stay of >24 hours.
Results: The rates of spontaneous preterm birth and neonatal intensive care admission were statistically significantly higher in the EO-ICP group (p0.05), however, the CAPO rate was significantly higher in the EO-ICP group (p=0.028). Receiver operator characteristic analysis revealed an optimal cut-off value of 33.5 μmol/L for the serum bile acid level, at which this parameter had 74% sensitivity and 68% specificity (area under the curve=0.759; p
Exploring the implications of ‘no net land take’ policy for spatial planning: the case of the Netherlands
Authors: Evers David
Published: May 2024

The European Union’s ‘no net land take’ (NNLT) target, which seeks to halt greenfield development by 2050, is very pertinent for planners. The present article investigates its potential impact with special attention for the Netherlands. Given that no single definition or methodology had been established at the EU level, land take was calculated over the 2000–2018 period for alternative definitions. A result is that qualitative approaches oriented to soil quality provide more scope for flexibility than quantitative approaches oriented towards land use. In addition, successful implementation of NNLT will depend on engaging with planners and planning practice.
Possible Anthropogenic Contributions to the LAMP-observed Surficial Icy Regolith within Lunar Polar Craters: A Comparison of Apollo and Starship Landings

Published: May 2024

This work assesses the potential of midsized and large human landing systems to deliver water from their exhaust plumes to cold traps within lunar polar craters. It has been estimated that a total of between 2 and 60 T of surficial water was sensed by the Lunar Reconnaissance Orbiter Lyman Alpha Mapping Project on the floors of the larger permanently shadowed south polar craters. This intrinsic surficial water sensed in the far-ultraviolet is thought to be in the form of a 0.3%–2% icy regolith in the top few hundred nanometers of the surface. We find that the six past Apollo Lunar Module midlatitude landings could contribute no more than 0.36 T of water mass to this existing, intrinsic surficial water in permanently shadowed regions (PSRs). However, we find that the Starship landing plume has the potential, in some cases, to deliver over 10 T of water to the PSRs, which is a substantial fraction (possibly >20%) of the existing intrinsic surficial water mass. This anthropogenic contribution could possibly overlay and mix with the naturally occurring icy regolith at the uppermost surface. A possible consequence is that the origin of the intrinsic surficial icy regolith, which is still undetermined, could be lost as it mixes with the extrinsic anthropogenic contribution. We suggest that existing and future orbital and landed assets be used to examine the effect of polar landers on the cold traps within PSRs.

Published: May 2024

A Agenda 2030 é uma temática imprescindível para a formação dos alunos, já que estes devem estar preparados para os novos desafios que a conjuntura global e local os impõe. É nessa concepção que este estudo objetiva refletir sobre a perspectiva de inserção de agendas ambientais nas escolas a partir de uma ação formativa com professores à luz dos Objetivos de Desenvolvimento Sustentável. O estudo é caracterizado como uma pesquisa de campo, com abordagem qualitativa, e foi desenvolvido com a participação de 65 docentes ligados à Secretaria de Educação do município de Carnaúba dos Dantas, no estado do Rio Grande do Norte-RN. Elaboramos uma oficina formativa sobre a Agenda 2030 e seus objetivos a fim de que os profissionais envolvidos fossem convidados a discutir e propor ações para a criação de uma agenda, de modo participativo, para o município onde trabalham. Com os dados obtidos no processo, foi possível perceber que os moldes propostos para a execução da formação foram propositivos e integrativos; que existem lacunas, principalmente no que diz respeito à Educação para a Sustentabilidade na prática docente, e que a possibilidade de extrapolação das práticas tradicionais nas escolas, quando se trata de sustentabilidade, é real, pois os docentes elaboraram propostas concretas (uma agenda) de forma crítica e participativa. Salientamos que este movimento de formação, construção e execução da agenda pode trazer resultados muito frutíferos, visto tratar-se de um processo construído de dentro para fora por agentes que pensaram no problema e nas demandas para resolvê-los.

Published: May 2024

Electric cars have many advantages over vehicles that require fossil fuels for their use. However, both types of cars are subject to problems related to brake squeal, which is a noise that causes discomfort for those inside the vehicle. In particular, this problem is more significant in electric cars because the motor operates silently compared to internal combustion engines, making the noise more obvious. In this context, the aim of this study is to perform a parametric analysis to verify the influence of design parameters on squeal in a cooled disc brake of an electric car. Therefore, finite element methods were used to analyse the brake geometry, which was subjected to static and modal analyses to extract complex eigenvalues and identify unstable modes. The simulation results indicated that the friction coefficient, stiffness of the components of system, and brake pressure are significant to the performance of the brake system, being the Young's modulus of the back plate the best parameter to minimize the brake squeal.

Published: May 2024

O Imposto sobre a Propriedade Territorial Urbana (IPTU) impacta na vida da população urbana e pode ser uma importante fonte de receita própria dos municípios. Este estudo teve como objetivo desenvolver um método disruptivo de arrecadação do IPTU, que busca reduzir o valor para o contribuinte sem comprometer a arrecadação no município de Feliz. A pesquisa se classifica como estudo de caso, quanto aos objetivos; qualiquantitativa, pela forma de abordagem do problema; e documental, pelos procedimentos técnicos utilizados. Mediante as etapas de definição da zona urbana, de georreferenciamento da área e consequente aumento da base cadastral, da atualização da planta genérica de valores e aplicação do método de cálculo por face de quadra, e do ajuste das alíquotas, chega-se ao novo IPTU. Foi analisado o período de 2014 a 2022, e a reestruturação reduziu para 86% da população contribuinte de 2021, sendo que o IPTU médio previsto para 2022 é 14,8% menor do que o do ano anterior. Porém, mesmo com a redução, a arrecadação prevista para 2022 supera a de 2021 em 6,04%. Conclui-se que a adoção, de forma planejada, das etapas propostas possibilita uma redução da carga tributária da população, sem comprometer o erário. O estudo contribui para o desenvolvimento do município, que aumenta sua arrecadação aplicando um imposto justo para a população, permitindo a continuidade da prestação de serviços públicos. Além disso, o método proposto poder ser replicado para outros municípios.

Authors: Pramanik Sabyasachi
Published: May 2024

Steganography is the practice of hiding confidential information inside apparently harmless media, and it plays a vital role in ensuring secure communication and safeguarding data. This chapter presents a steganography program that is both free and open-source. It allows users to hide plaintext payloads inside halftone photographs. Additionally, the software includes a utility for extracting these payloads from images that were created using the steganography tool. One notable characteristic of this utility is its ability to distribute payloads over many outputs, which increases payload security by preventing illegal extraction and eliminates the need for the original picture during payload retrieval. In addition, the utility offers quantitative evaluations of picture quality for the generated images. These evaluations are used in this study to demonstrate the effectiveness of the steganography approach being discussed.

Published: May 2024

Quantitative examination of human brain development when the individual is still in the womb is essential for aberrant characterisation. Therefore, the segmentation of magnetic resonance images (MRI) is a valuable asset for quantitative analysis. Conversely, there is little variation within cohorts of foetal brain MRI annotated datasets, which makes it difficult to create automatic segmentation methods. Within this framework, the authors suggest harnessing the potential of foetal brain MRI super-resolution (SR) reconstruction techniques to produce several re-creations of a one subject with varied parameters. As a data augmentation strategy, this would work well without requiring any tuning. In general, the latter makes a major improvement to the generalisation of segmentation approaches over pipelines. When it comes to the diagnosis and treatment of neurological illnesses, the accurate segmentation of brain magnetic resonance imaging (MRI) is absolutely necessary.

Authors: Praveena A. , Yogeshwari M.
Published: May 2024

Alzheimer's disease is the most typical neurological disorder. There are about 45 million people who have this illness. Alzheimer's disease (AD) is a neurodegenerative disorder that impacts neurons, brain cells, and neurotransmitters and affects perception, memory, and behavior. Even though the symptoms are mild at first, they always worsen. There is currently no cure for AD. However, taking recommended medications can slow the spread of the illness. Early Alzheimer's diagnosis is, therefore, crucial for both therapy and future research. The main challenges in early AD identification using various classification algorithms are the extremely low numbers of trained samples and greater feature descriptions. The disease rendered sufferers' incapable of thinking, reading, and doing a wide range of other tasks. By anticipating the disease, a machine learning system may be able to lessen this issue. Finding dementia in a range of persons is the main objective.
Evaluation of an Intensive Care Unit Sepsis Alert in Critically Ill Medical Patients
Authors: Rich Rebecca L. , Montero Jennifer M. , Dillon Kyle E. , Condon Patrick , Vadaparampil Mathew
Published: May 2024

Background

Sepsis alerts commonly used for intensive care unit (ICU) patients can lead to alert fatigue because these patients generally meet 1 or more of the criteria for systemic inflammatory response syndrome. To identify ICU patients at greatest risk for sepsis-related consequences, an ICU-specific sepsis alert was implemented.

Objective

To evaluate an ICU sepsis alert based on modified criteria for systemic inflammatory response syndrome among critically ill medical patients.

Methods

This retrospective evaluation was conducted at a comprehensive tertiary referral center. Patients included were at least 18 years old, were admitted to the critical care medicine service, and had at least 1 sepsis alert between January 1 and February 29, 2020. The sepsis alert identified patients meeting at least 2 modified systemic inflammatory response syndrome criteria (white blood cell count, <4000/μL or >12 000/μL; body temperature, <36 °C or >38.3 °C; heart rate, >110/min; and respiratory rate, >21/min), with at least 1 of the 2 criteria being white blood cell count or body temperature.

Results

For 128 alerts evaluated, the positive predictive value was 72%. Of 713 patients who were admitted to the critical care medicine service and did not have a sepsis alert, 7 received a sepsis diagnosis. The ICU sepsis alert had a negative predictive value of 99%, sensitivity of 92.9%, and specificity of 95.1%.

Conclusions

An ICU sepsis alert using modified systemic inflammatory response syndrome criteria was effective for identifying sepsis in critically ill medical patients.
Sources of Sound Exposure in Pediatric Critical Care
Authors: Kalvas Laura Beth , Harrison Tondi M.
Published: May 2024

Background

Sound levels in the pediatric intensive care unit (PICU) are often above recommended levels, but few researchers have identified the sound sources contributing to high levels.

Objectives

To identify sources of PICU sound exposure.

Methods

This was a secondary analysis of continuous bedside video and dosimeter data (n = 220.7 hours). A reliable coding scheme developed to identify sound sources in the adult ICU was modified for pediatrics. Proportions of sound sources were compared between times of high (≥45 dB) and low (<45 dB) sound, during day (7 AM to 6:59 PM) and night (7 PM to 6:59 AM) shifts, and during sound peaks (≥70 dB).

Results

Overall, family vocalizations (38% of observation time, n = 83.9 hours), clinician vocalizations (32%, n = 70.6 hours), and child nonverbal vocalizations (29.4%, n = 64.9 hours) were the main human sound sources. Media sounds (57.7%, n = 127.3 hours), general activity (40.7%, n = 89.8 hours), and medical equipment (31.3%, n = 69.1 hours) were the main environmental sound sources. Media sounds occurred in more than half of video hours. Child nonverbal (71.6%, n = 10.2 hours) and family vocalizations (63.2%, n = 9 hours) were highly prevalent during sound peaks. General activity (32.1%, n = 33.2 hours), clinician vocalizations (22.5%, n = 23.3 hours), and medical equipment sounds (20.6, n = 21.3 hours) were prevalent during night shifts.

Conclusions

Clinicians should partner with families to limit nighttime PICU noise pollution. Large-scale studies using this reliable coding scheme are needed to understand the PICU sound environment.
Reliability-Based Assessment of the Residual Collapse Strength for Damaged Tubes Scanned with Ultrasonic Log

Published: May 2024

This work presents a casing integrity study that begins with data collected from an ultrasonic log inspection and progresses to the estimation of the residual collapse strength of damaged tubes, using a probabilistic-based Finite Element (FE) modeling. The goal is to provide a data-driven enhanced assessment of the structural integrity of tubular components in a high complexity and risk environment, as in the case of the Brazilian pre-salt region. Damage identification employs a technique that seeks an ellipse geometry resembling the probable intact shape of the casing's inner wall. Then, the residual collapse strength is estimated by using physically and geometrically nonlinear FE modeling. The probabilistic analysis is carried out using the First Order Reliability Method (FORM), considering the FE modeling limit state and random variables associated with material and geometry of the tubulars, as well as damage parameters such as maximum depth and position. Geometries of ovalized and eccentric cross sections, associated with multiple damages at various intensities and positions are evaluated. The nonlinear FE modeling allowed the capture of different collapse modes of the element, depending on its slenderness and damage configuration. Through the probabilistic approach, it became possible to account for inherent uncertainties associated with different design and damage parameters, enabling the calculation of the probability of element failure. In the conducted case study, the loads were set equal to the collapse pressures calculated with design equations from the literature. As the obtained probability of failure did not meet a pre-defined target, a finding procedure was implemented to achieve an adequate collapse pressure for design purposes. Although this procedure is computationally expensive and only two critical cross section were assessed, it mitigates many simplifications commonly observed in other works, and the results can significantly contribute to casing design and intervention plans.

Tendencias y desafíos en la comprensión del límite: un estudio exploratorio con estudiantes de Biotecnología en la Universidad Michoacana de San Nicolás de Hidalgo.
Authors: Rojas Maldonado Erick Radaí
Published: May 2024

El Cálculo es esencial en ingenierías, pero entender conceptos como el límite es un desafío. Esta dificultad ha llevado a altas tasas de fracaso y deserción en la Universidad Michoacana de San Nicolás de Hidalgo. Para abordar esto, se implementó una propuesta didáctica de Aquere et al. (2009) para mejorar el aprendizaje de los límites. Se realizó una prueba estandarizada y se analizó su impacto en estudiantes de biotecnología. Los resultados indican que no hay una diferencia significativa entre la estrategia didáctica y la enseñanza tradicional; sin embargo, estos hallazgos pueden guiar a profesores menos experimentados en su práctica docente.
Corporalidad subjetiva, histórica y cultural en torno a la Educación Física latinoamericana. Una perspectiva epistemológica, curricular y decolonial.
Authors: Mujica Johnson Felipe
Published: May 2024

Se ha desarrollado este ensayo que tiene por objetivo comprender parcialmente el giro narrativo hacia lo corporal en América Latina y las posibilidades curriculares que genera en la educación escolar. Se reconoce que en diferentes países de América Latina se ha estado configurando una narrativa sobre la corporalidad humana que promueve una interpretación subjetiva, histórica y cultural de las experiencias educativas enfocadas en lo corporal. Esta narrativa se contrapone a la perspectiva colonial, biomédica y neoliberal del cuerpo en la Educación Física, por lo que se posiciona como una corriente superadora que avanza hacia la diversidad y complejidad de esta disciplina pedagógica. A su vez, permite concebir un currículum escolar de corte experiencial y crítico.

Published: May 2024

El reconocimiento, respeto e inclusión de la diversidad de género y de las personas de la comunidad Trans son indispensables en los entornos universitarios, pero no son fáciles de lograr. A través de una revisión narrativa de la experiencia recogida tanto en países latinoamericanos como en el extranjero se identificaron cinco áreas principales de acción para lograr una inclusión efectiva. Con base en este conocimiento, en este trabajo se propone un Modelo Universitario Trans Inclusivo (MUTI), dirigido a esquematizar y operacionalizar la relación entre la comunidad Trans y las universidades en las áreas de Enseñanza, Investigación, Instalaciones Universitarias, Gestión Institucional y Proyectos de Extensión.
