Authors: Negrete Ana Carolina Aguilera , De Albuquerque Yago Abreu , Carelli Renan de Oliveira
Published: January 2025

Este artigo visa contribuir para o conhecimento da sociedade brasileira sob o vasto potencial econômico da área denominada como Amazônia Azul. Neste sentido, parte-se da apresentação do potencial das fontes de riqueza que tem crescido desde a descoberta da camada do pré-sal e da exploração do petróleo. Além disso, busca-se ratificar a importância que deve ser dada as políticas adotadas e aos investimentos nos meios operativos que devem ser empregados para o processo de dissuasão e projeção de poder da Marinha do Brasil sob seu patrimônio em vista de um cenário global. Atualmente, a utilização e aperfeiçoamento da Base Industrial de Defesa se tornam cada vez mais significativos e vultosos para a sociedade brasileira, tanto nos aspectos civis e militares. Devido a essa valorosa visão positiva relativa ao engrandecimento da Indústria de Defesa Brasileira sobrevém os impetuosos projetos que vem sendo desenvolvidos pela MB: o Programa de Obtenção das Fragatas Classe Tamandaré (PFCT), tendo em vista a significativa importância para a indústria naval e para a nação brasileira como um todo, pois as fragatas estão sendo construídas em território nacional. Por fim, busca-se demonstrar a relevância da manutenção dos programas estratégicos como o PROSUB no longo prazo e a necessidade de sensibilizar as autoridades políticas para o desenvolvimento do setor de defesa do país.

Authors: Peres Roberio , De Souza Gomes Jacqueline
Published: January 2025

Este trabalho traz reflexões sobre a modalidade Educação de Jovens e Adultos (EJA) desenvolvida no município de Aperibé/RJ. Metodologicamente, utilizamos a pesquisa bibliográfica de cunho exploratório. Com o avançar da pesquisa, concluímos que, até então, não havia sido realizado nenhum trabalho anterior a este respeito sobre o município de Aperibé/RJ. Assim, toda esta investigação busca trazer referenciais iniciais e questões que possam ecoar dos projetos de EJA desenvolvidos em cada instituição de ensino do município, quer na rede municipal, quer na rede estadual. Consultamos, ainda, o acervo da Casa de Cultura de Aperibé, no qual foram resgatadas as memórias da fundação e história da cidade. Trazemos reflexões sobre a EJA que se desdobram destas memórias e nos revelam desafios diários pulsantes na história do município. Este artigo busca pensar o ser humano a partir da educação, pensar a educação a partir da EJA e pensar a EJA como reflexo das estruturas sociais, como uma modalidade que pode se configurar em uma rede de relações cooperativas entre indivíduos a fim de mudar o funcionamento da sociedade em que vivem. Pessoas que, para isto, buscam ampliar os próprios conhecimentos, o que apenas será possível se respeitarmos o sujeito como protagonista nesta ação.
A dependência dos municípios do Estado do Rio de Janeiro em relação aos repasses federal e estadual
Authors: Rodrigues Cordeiro Daniel , Siqueira da Cruz Sérgio , Da Costa Oliveira Beatriz , Rabelo Sá Rego Henrique , Elias Montibeler Everlam
Published: January 2025

O objetivo geral do presente trabalho foi o de verificar o nível de dependência dos municípios do estado do Rio de Janeiro em relação aos repasses federal e estadual. Os objetivos secundários estavam relacionados a identificar os municípios que se agrupam em relação a dependência dos repasses e verificar se havia concentração por região desses municípios agrupados. A técnica de análise de dados utilizada foi a da análise de cluster. Os dados foram coletados no portal SICONFI/FINBRA e nos portais das Prefeituras e a amostra foi composta pelos municípios do estado do Rio de Janeiro. Notou-se que dos dez maiores municípios, em termo populacional, cinco deles tiveram a média de repasses maior do que a média de arrecadação própria, sendo eles: Duque de Caxias, Campos dos Goytacazes, Belford Roxo, São João de Meriti e Volta Redonda, o que significa que os municípios maiores também dependem dos repasses para seu funcionamento, porém, com uma proporção menor do que a dos municípios pequenos. O presente trabalho demonstrou resultados importantes para o contexto regional do estado do Rio de Janeiro, demonstrando que as cidades que demonstraram uma capacidade arrecadatória maior são as que possuem atividades portuárias e de apoio à bases offshore, como o caso do Rio de Janeiro, Macaé, Niterói e Itaguaí. Outro resultado importante demonstrado no trabalho foi o de que os municípios menores tem um alto índice de dependência dos repasses dos entes federativos e contam com pouca atividade produtiva, ocasionando uma baixa capacidade arrecadatória.
Estudo sobre a viabilidade econômica dos campos maduros na Bacia de Campos
Authors: Bastos Matheus , Das Chagas Ribeiro Alcimar
Published: January 2025

As áreas maduras são ativos de produção de óleo e gás natural que estão próximos ao fim de sua vida útil econômica, mas que, no Brasil, são abandonados precocemente. Este estudo tem como objetivo avaliar essaoportunidade de negócio que até então não tem sido explorada. A produção nacional de petróleo e gás naturalcresceu nos últimos anos, porém, se analisada mais a fundo, isso se deve aos projetos ocorridos no pré-sal da Petrobras, enquanto grande parte dos projetos do pós-sal apresentam declínio de produção. Com os recentes incentivos públicos, aliados à uma evolução da engenharia e barateamento de processos, foi possível estender a vida útil de diversos campos em produção no país, aumentando a viabilidade econômica dos mesmos por um período maior. Para embasar essa teoria, será feita uma análise de indicadores financeiros e operacionais dealguns poços na bacia de Campos, que se encontravam em declínio de produção e sub-explorados, até serem arrematados em leilões da ANP, por empresas focadas na exploração de campos maduros. Desde então, após uma série de decisões e estratégias tomadas por essas empresas, possibilitou-se a revitalização dos campos e o cenário se tornou outro, muito mais lucrativo. Além do aspecto operacional, serão levantadas nas consideraçõesfinais aspectos sociais e ambientais, além de uma análise global do trabalho.

el ideal de ciudadanía democrática en el proyecto de filosofía para niños de matthew lipman
Authors: Mora alonso César augusto , Cruz rivera Bibiana judith
Published: January 2025

Uno de los pilares del proyecto de Filosofía para Niños de Matthew Lipman lo constituye su concepción de ciudadanía democrática, en razón de que es la encargada de promover y preservar el establecimiento de una democracia de alta calidad, que representa mucho más que la mera idea de sistema de gobierno o de régimen político. En efecto, la ciudadanía democrática asume esta forma de organización de la sociedad como una manera de vivir, lo que debe traducirse en que las acciones de las personas sean solidarias y transformadoras, algo que resultaría del despliegue de las habilidades superiores del pensamiento. Por tanto, no es gratuito que esta propuesta de educación filosófica para la infancia apunte a la formación de ciudadanos razonables, ya que una tarea así requiere de la propiciación de ciertas condiciones que favorezcan el desarrollo del pensamiento multidimensional en las aulas de clase; en este sentido, el arribo a una democracia plena y reconstructiva requiere de una preparación integral en las comunidades de investigación, de cara a un ejercicio efectivo de la ciudadanía democrática. De modo que el propósito de este artículo consiste en evidenciar el lugar privilegiado que ocupa dicha ciudadanía en el constructo del filósofo y pedagogo norteamericano.

Recepção, crítica e homossexualidade em Bom-crioulo, de Adolfo Caminha
Authors: Alves de Souza Giovane
Published: January 2025

Neste trabalho, pretendemos analisar a homossexualidade em Bom-Crioulo, de Adolfo Caminha, a partir da estética realista-naturalista, em voga na época, e das noções acerca da sexualidade vigentes no fim do século XIX. Para tal, nos respaldamos nas contribuições de Howes (2005), Priore (2011), Green (2019), dentre outros(as). A análise visa compreender como, a partir da representação de um homem negro, marinheiro, ex-escravizado, alcóolatra e homossexual, Caminha, apesar de dialogar com os discursos de sua época, acabou criando uma narrativa que possibilitou se falar acerca da homossexualidade de uma maneira inédita na literatura brasileira da época.

Multimodal treatment of skin during hormonal changes
Authors: Dennison Tracey
Published: January 2025

Treatment planning can be difficult. We have a finite number of resources compared to an often seemingly infinite number of issues which our patient may present with. Skin health is not a one size fits all approach and therefore we need to review patients holistically and understand the physiology beyond ‘skin deep’. During hormonal changes, symptoms such as hot flushes, night sweats, itching, dryness and anxiety are commonly reported and are interlinked with gut health, stress, and sleep issues. This paper explores the multimodal treatment of skin during menopause, examining the physiological changes and related interventions to maintain skin health.

Microneedling: monotherapy or adjuvant treatment?
Authors: Ramadan Francesca
Published: January 2025

Microneedling, a minimally invasive procedure involving repeated puncturing of the skin with sterilized microneedles, has gained popularity for treating various dermatological concerns. Its ability to stimulate collagen production makes it effective for skin rejuvenation, scar reduction, and hair regrowth. Recent studies demonstrate its enhanced efficacy when combined with other treatments, such as minoxidil, platelet-rich plasma, and exosomes for hair regeneration. Additionally, microneedling shows promise in managing conditions like vitiligo and melasma when used alongside topical therapies. The expanding applications of microneedling highlight its versatility, with combination therapies proving more effective than monotherapies for optimal patient outcomes.

Authors: Mahmoodi Nima
Published: January 2025

This case study explores the use of the Emerald Laser™ for whole-body fat loss, enhanced cellular health, and improved wellness. Aesthetic practices are shifting toward a more holistic approach that integrates aesthetics with wellness, addressing not just appearance but overall health. The study highlights the increasing demand for non-invasive fat loss treatments like low-level laser therapy (LLLT), which provides a safer alternative to traditional methods like surgery or weight loss drugs. The Emerald Laser™ targets fat cells, shrinking them without side effects, while promoting mitochondrial health and cellular regeneration. The case study of a 43-year-old woman demonstrates significant fat loss and improved wellbeing, illustrating the potential for this treatment to enhance both physical appearance and overall health, particularly by reducing inflammation and slowing premature aging. This fusion of aesthetic and wellness treatments reflects a broader trend towards preventative care and holistic health in medical practices.
Effective management of chronic urticaria
Authors: Lawton Sandra
Published: January 2025

Urticaria (also known as welts, hives, weals, wheals or nettle rash) is usually divided into acute and chronic forms, becoming chronic when daily or almost daily wheals continue for 6 weeks or more, although many attacks of acute urticaria settle much more quickly. The most common underlying mechanism is the release of histamine from mast cells with consequent capillary dilatation and tissue oedema. In the UK, approximately 15% of people experience urticaria at some time in their lives and for around 40–50% of people with urticaria, the cause of their condition is unknown. This article will provide an overview of chronic urticaria to include the clinical signs, history, diagnosis and management principles, signposting to current guidance, patient information and further resources.

Grief Capital, Grief Activism: The Brief Life of Mamie Till Bradley's NAACP Tour
Authors: Williams Rhaisa Kameela
Published: January 2025

Abstract: In 1955, Mamie Till Bradley spoke throughout the country on behalf of the National Association for the Advancement of Colored People (NAACP) to bring justice to her recently murdered son, Emmett Till. While most scholarship focuses on Bradley's choice to publicize her son's mutilated body, I analyze her understudied NAACP-sponsored grief tour and her ensuing public fallout with the organization. Focusing on her attempts to create an infrastructure of care and compensation for herself, I forward the concept of grief capital to demonstrate how Black women and institutions make decisions based on the financial substrates of Black maternal grief.
On the design of efficient fiber-wireless architectures to enable multigigabit visible light communication
Authors: Loureiro Pedro A. , Brandão Bruno T. , Yahyaoui Salma , Guiomar Fernando P. , Monteiro Paulo P.
Published: January 2025

The surge in demand for wireless communication has placed significant strain on existing radio networks, which are struggling to accommodate the rapidly increasing number of mobile and fixed wireless devices. In response to this challenge, industry and academia have collaborated to explore alternative radio access technologies capable of supporting this continuous growth. Visible light communication (VLC) has emerged as a promising alternative due to the hundreds of terahertz of unlicensed bandwidth available for wireless communication. Despite its undisputable potential for ultrahigh-speed communication, the interface between the VLC wireless access and the fiber distribution network is still largely unexplored. Notably, this issue becomes more challenging when dealing with multicolored VLC systems, such as those employing RGB multiplexing. Following this research gap, in this work, we focus our attention on the design of efficient optical/electrical interfaces that can synergistically merge the fiber and VLC sections of an integrated fiber-wireless network. To that end, two fundamental architectural options are proposed and experimentally assessed, resorting to either optical or electrical multiplexing of the VLC constituent colors. From our experimental analysis, similar RGB-VLC data rates of 13–15 Gbit/s could be achieved using both fiber-wireless interface architectures. The choice of the most adequate solution is then fundamentally dependent on a number of network design options and requirements. While electrical multiplexing is deemed to enable more spectrally efficient utilization of the fiber transport network, optical multiplexing provides a simpler infrared-to-visible interface using cost-efficient commercial off-the-shelf equipment.
On the performance and fiber nonlinearity modeling of learned digital back-propagation in the presence of DAC and ADC quantization noise
Authors: Li Qingyuan , Chen Bin , Lei Yi , Liang Zhiwei
Published: January 2025

The noise and nonlinear signal distortion introduced by transceiver and signal propagation limit the achievable signal-to-noise ratio in coherent optical communication systems. As an efficient nonlinear compensation (NLC) scheme, digital back-propagation (DBP) algorithm is known to compensate for deterministic nonlinear interactions, but not for signal-noise interactions. In contrast, learned digital back-propagation (LDBP), which utilizing data-driven optimization based on physical models, offers what we believe to be a new approach to end-to-end compensation. In this paper, we investigate the impact of quantization noise due to the finite resolution of digital-to-analog converter and analog-to-digital converter on the performance of LDBP, and propose a modified analytical nonlinear interference (NLI) model by accounting the nonlinear beating between transceiver quantization noise and signal for LDBP. The split-step simulations show that the parameters of LDBP, which trained at an ideal link without quantization noise, demonstrate significant adaptability to the link with quantization noise. The results also indicate that the impact of quantization noise on LDBP can be less than that on DBP. Meanwhile, based on the simulations, the effectiveness of the proposed modified analytical NLI model is validated, and the results show excellent agreement between the proposed modified analytical model and the simulations, with discrepancies within 0.2 dB.
Analysis of a photonic crystal fiber SPR sensor based on dual polarization direction and two different metal layers
Authors: Jiao Shengxi , Gao Zhenqiu
Published: January 2025

A photonic crystal fiber (PCF) with a dual-groove-based surface plasmon resonance (SPR) sensor is designed. The two grooves are positioned on the upper and right sides of the sensor. The gold (Au) and silver (Ag) films are plated on the inner walls of the two groove-shaped detection channels as the plasmonic materials. A thin layer of titanium dioxide (TiO2) is applied to the outer layer of the gold (Au) and silver (Ag) films to enhance the sensitivity of the sensor and prevent oxidation of the metal layers. The sensor designed in this paper uses different directions of polarization combined with the characteristics of different metals when the SPR effect occurs to realize the detection of two parameters. The effect of structural parameters on the sensing properties and loss spectrum is numerically analyzed by finite element method (FEM). The detection range of the refractive index sensor is from 1.36 to 1.41. In the upper channel, the maximum wavelength sensitivity (WS) can reach 14,500 nm/RIU, corresponding to a resolution of 6.90 × 10−6 RIU. In the right channel, the maximum WS can reach 13,600 nm/RIU, corresponding to a resolution of 7.36 × 10−6 RIU. The simulation results suggest that the designed dual-channel sensor can realize highly sensitive detection of two analytes simultaneously, offering wide applications in biomedical analysis and environmental monitoring.

Published: January 2025

By using polarization-resolved common-path diffraction phase microscope
coupled with spin-to-orbit converter, we experimentally study
two dimensional in-plane distributions of amplitude and phase
of light transmitted through a spherulite formed in a frustrated
cholesteric liquid crystal cell.
These distributions measured at different orientations of the output linear polarizer (analyzer) are used to obtain the orbital angular momentum (OAM) spectra characterizing OAM content of the beam.
The experimental data are found to be in good agreement with
the theoretical results describing both the distributions and the OAM spectra based on analytically designed model of toron-like localized liquid crystal structures.
We show that the OAM spectrum can be controlled by
changing the analyzer azimuth angle
so that the dominant mode evolves between
the limiting cases of the vortex mode with Ι=-2
and the vortex-free mode with l=0.
Evaluation of Global South’s efficiency at the Summer Olympics
Authors: Klöcker Julian Alexander , Daumann Frank
Published: January 2025

States differ significantly in international sports competitions in how they use the resources they have and whether they do so in an efficient manner. In this paper, we investigate the efficiency of the nations from the so-called “Global South”, in total 52 states, during the 2000–2024 Summer Olympics. By doing this, our paper is the first using the Bayesian stochastic frontier analysis for exploring the performance of the states of the Global South. We perform an age decomposition, which shows that the 25–29 and 30–34 age cohorts contribute the most to Olympic performance. Our findings also suggests that transient efficiencies are higher than persistent efficiencies in a majority of the analyzed nations. Our analysis represents an important contribution in analyzing developing states‘ efficiency in elite sports.
Electroconvulsive shock and transcranial magnetic stimulation do not alter the survival or spine density of adult-born striatal neurons
Authors: Gaertner Tara , Zhang Tian Rui , Askari Baran , Vila-Rodriguez Fidel , Snyder Jason S.
Published: January 2025

Adult neurogenesis has most often been studied in the hippocampus and subventricular zone-olfactory bulb, where newborn neurons contribute to a variety of behaviors. A handful of studies have also investigated adult neurogenesis in other brain regions, but relatively little is known about the properties of neurons added to non-canonical areas. One such region is the striatum. Adult-born striatal neurons have been described in both rodents and humans, but the regulation of these neurons is poorly understood. Since striatal dysfunction occurs in Parkinson’s disease, which is amenable to neurostimulation therapies, we investigated whether electroconvulsive shock (ECS) or transcranial magnetic stimulation (rTMS) modulate neuroplasticity of adult-born striatal neurons. Adult-born cells were labelled in transgenic mice and 8 days later mice were given 10 stimulations over the course of 3 weeks. Adult-born striatal neurons were consistently observed in all groups. Their dendritic morphology and expression of DARPP32 and NeuN indicated a medium spiny neuron phenotype. However, neither ECS nor rTMS altered the number of new neurons, and both treatments also had no effect on the density of dendritic spines compared to unstimulated controls. These results suggest that neither ECS nor rTMS alter early neuronal survival or morphological plasticity at postsynaptic sites in the striatum.

The objective of this study was to develop and to test the validity and reliability of a survey aimed to evaluate internal and external factors associated with college food insecurity. Researchers used a mixed methods approach to evaluate the College Perspectives around Food Insecurity survey. Survey items were constructed from interview data and assigned a social cognitive theory concept (environment, personal, or behavior). Two rounds of expert reviews established content validity (Round 1, n = 3; Round 2, n = 2). Researchers evaluated face validity through two rounds of cognitive interviews with college students 18+ years old (Round 1, n = 9; Round 2, n = 16) and tested survey reliability (n = 105). Researchers used descriptive statistics, test-retest reliability statistics, and Cronbach’s alpha scores for data analysis. The initial survey contained 143 items. After feedback from expert reviewers and cognitive interviews, the final survey contained 99 items. Test-retest reliability was 0.99, and Cronbach’s alpha scores were 0.74 for environment, 0.47 for personal, and 0.39 for behavior. The College Perspectives around Food Insecurity survey can be used to better understand internal and external factors associated with food insecurity in college students, which can inform interventions aimed at assisting this population.
Open seas, open systems
Authors: Collins Susan
Published: January 2025

This article traces the author’s utilization of the sea as both generative device and communications channel, from an early student experiment sending out messages in bottles, and Transporting Skies, an exhibition made in response to the pioneering telegraph communications station at Porthcurno near Newlyn in Cornwall, one of the first places to be ‘on-line’ in a contemporary sense, to the present day. Reflecting on an ongoing series of works employing imagery captured and transmitted by network cameras pixel by pixel in real time from remote locations, including Seascape, which took in the panorama of the south-east coast of England, to the most recent, Current II, where the camera is situated within the sea itself, the article explores the sea as both an actual and metaphorical open system for generating artworks. It examines its role as collaborative ‘actor’ in the making of the author’s works, reflecting on the parameters it offers in the form of real-world analogue variables – comprising light, day, night, weather, the sun, the moon, the tides and the seasons and how this can surface new ways of observing and understanding temporality, our environment and ourselves.
The Constitution of the Sea: New boundaries and identity through watery, transdisciplinary artistic practice
Authors: Austen Kat
Published: January 2025

What is it to be the sea? Explorations of the constitution of the sea – what it comprises, where its borders are, how it incorporates novel entities – offer meaningful insights into the nature of boundaries and identity that are as relevant for humans as they are for the imperilled oceans. At the advent of the post-Anthropocene, when global processes perceptibly react to human impacts, this article elaborates on watery artistic investigations inspired by the mutability and permeability of seas. Anchoring its arguments in wide-ranging examples from transdisciplinary artistic practices, the article challenges conventional notions of boundaries and identity, proposing a new way of conceiving of the self, inspired for and by the seas: The Constitution of the Sea.
Reflections on sea, listening and sound installations: A conversation with Félix Blume
Authors: Blume Félix , Psarras Bill
Published: January 2025

Both the sound and the sea are characterized by a constant fluidity and transformation, which has been considered as a creative foundation for expanded sonic practices that identify, capture and experiment with natural elements. The text aims to explore how the idea of sonification as a process of translating qualities and data into sound constitutes the departure point towards contemporary sound practices that encourage deeper listening and immersive experiences. Taking the sea-responsive sound installations of French artist Félix Blume, Rumors from the Sea and Suspiros as a foundation, the article presents a reflective conversation between Félix Blume and Bill Psarras on aspects of such artworks that highlight ideas of sea and limens, listening experience, sound ecology and sonic instruments through performative, inventive and participatory lenses.

Published: January 2025

Background and Aim: The IPB-D2 chicken, a potential disease-resistant local Indonesian line, has been developed to improve poultry health and productivity for small-scale farmers. This study aimed to characterize the disease resistance traits of IPB-D2 chickens by analyzing key immunological parameters, including immunoglobulin Y (IgY) concentration, Newcastle disease (ND) antibody titers, and leukocyte profiles.

Materials and Methods: A total of 100 IPB-D2 chickens were studied. Blood samples from 21-week-old chickens were collected for analysis of IgY concentrations using indirect enzyme-linked immunosorbent assay, ND antibody titers using the hemagglutination inhibition test, and leukocyte profiling using the Giemsa staining method. Correlations between parameters were determined using Pearson’s correlation analysis in RStudio.

Results: The findings revealed that IPB-D2 chickens exhibited higher IgY concentrations, leukocyte counts, heterophil levels, and monocyte counts compared to their IPB-D1 progenitors. However, ND antibody titers in IPB-D2 chickens were lower than the protective threshold. Significant positive correlations were observed between leukocytes and lymphocytes, and negative correlations were identified between heterophils and lymphocytes.

Conclusion: IPB-D2 chickens demonstrated a well-balanced immune system with enhanced non-specific (leukocyte and heterophil) and specific (IgY) immune responses. These traits highlight their potential as a disease-resistant poultry line. Future research should focus on molecular selection through transcriptomic analysis to identify candidate genes associated with disease resistance traits, enabling further genetic improvements.

Keywords: IPB-D2 chicken, immunoglobulin Y concentration, ND antibody titer, leukocyte profile.

La exploración de nuevas aplicaciones de materiales y productos existentes para la construcción es una estrategia para agregar valor a sistemas tradicionales. El propósito de esta investigación es estimar el rendimiento térmico de la implementación de placas de fibrocemento y paja como sistemas constructivos de aislamiento en muros tradicionales de gres y concreto. La metodología es experimental y se divide en dos partes: el diseño del sistema y el análisis de la transferencia de calor. En primer lugar, el diseño explora cuatro tipologías de aislamiento exterior y cuatro tipologías de aislamiento interior conformadas con placas de fibrocemento y paja en muros conbloques de concreto y bloques de arcilla cocida. En segundo lugar, el análisis de la transferencia de calor determina la transmitancia térmica, distribución de temperaturas, flujos de calor a través decálculos y simulaciones en ANSYS. Los resultados indican que el aislamiento más eficiente está conformado con placa de fibrocemento porque disminuye la transmitancia entre el 50,50 % y el 63,59 % y reduce las temperaturas de las superficies interiores entre 13,61 °C y 14,33 °C. Por otra parte, las tipologías con placa de fibrocemento y paja mejoran en menor medida la transmitancia, entre el 36,41 % y 49,46 % y reducen las temperaturas interiores alrededor de 7 °C, comparados con los muros tradicionales. En definitiva, el sistema de revestimiento ofrece una alternativa de amortiguamiento de la transferencia de calor en muros de bloque de concreto y arcilla cocida en zonas de clima cálido como Cúcuta, Colombia.

Authors: Fraile-Narváez Marcelo
Published: January 2025

El diseño biodigital y la inteligencia artificial (IA) son dos disciplinas emergentes que ofrecen un enfoque prometedor para la creación de soluciones innovadoras en la construcción de un futuro sostenible. La convergencia de ambas disciplinas busca desarrollar una arquitectura viva, que imite el pensamiento biológico, con el objetivo de producir sistemas autónomos y sostenibles. Los edificios generados desde este punto de vista pueden obtener energía mediante la fotosíntesis, regular su temperatura de forma autónoma, purificar el aire interior y optimizar su rendimiento, y reducir así su impacto ambiental. Este trabajo tiene como objetivo explorar los procesos que buscan la integración del diseño biodigital y la IA para producir resultados innovadores y sostenibles en el campo proyectual. A través del análisis de casos, se examinan las ventajas y desventajas de la unión del diseño biodigital y la IA, considerando su efecto tanto ambiental como social. Este artículo ofrece una nueva perspectiva sobre la interacción entre ambas disciplinas, resaltando su potencial para transformar la arquitectura actual y lograr un futuro habitable y respetuoso con el medio ambiente.

En los inicios de la formación del arquitecto generalmente se ensaya con diversos ejercicios de empírea pura con argumentos lógicos y proceso de toma de decisiones propios de la experiencia de cada docente que replica a manera de modelo en los estudiantes. El propósito es que cada estudiante por medio del aprendizaje de toma de decisiones de la estrategia didáctica asuma sus propios procesos para resolver su proyecto arquitectónico. La investigación de diseño fue cuasiexperimental, tuvo como muestra a 18 estudiantes del taller de proyecto 1, en el que se examinó el antes y el después de tres ensayos proyectuales correspondientes a cada unidad de estudio, evaluados con la rúbrica analítica. El sistema estructurado de toma de decisiones pre proyectual y proyectual del proyecto arquitectónico en la formación inicial, condujo a una mejora significativa en el aprendizaje, con un crecimiento del 45 % en comparación con el inicio del estudio. Además, se observó una mejora significativa en las dimensiones del sentido artístico, sentido de diseño, imaginación plástica y sentido constructivo. Los resultados revelan que los estudiantes lograron, mostrar una tendencia ascendente de 25  % en los puntajes finales de cada unidad, la implementación de la estrategia didáctica se mostró como un factor relevante en la formación inicial del arquitecto, fomentando el desarrollo de habilidades de toma de decisiones propias y contribuyendo al conocimiento autónomo de los estudiantes.

Authors: Morales-Guzmán Carlos César , Ceballos-Vargas Jesus
Published: January 2025

Esta investigación presenta una alternativa tecnológica para el reúso de un material, actualmente en condición de desecho en la ciudad, que representa un contaminante obstructivo y visual. El porcentaje de aprovechamiento del reciclado de tereftalato de polietileno (PET, por sus iniciales en inglés) es bajo o nulo, por lo que en este trabajo se plantea el aprovechamiento de dicho material en condición de desuso. Se ha identificado una nueva cadena de valor con el diseño de una mezcla de concreto en la que se emplee el reciclado de PET como agregado. En este estudio se  hizo un trabajo de recolección, limpieza, triturado y tamizado de PET, con el fin de utilizar el producto reciclado en el diseño de la mezcla para la fabricación de mobiliario urbano. En consecuencia, los resultados indican la probable factibilidad del uso del PET como agregado en una concentración del 5 % con potencialidad de hasta el 10 % con una resistencia compresiva entre 167-132 kg/cm2.

Este artículo aborda la pregunta de investigación: ¿cómo percibe la juventud madrileña la arquitecturahostil y los efectos que esta provoca? Se centra en el impacto de la arquitectura hostil en Madrid,destacando su influencia en los jóvenes. Se realizó un estudio cualitativo, utilizando la técnica dePhotovoice, el cual reveló que esta práctica arquitectónica genera malestar, desidentificación conel entorno y discriminación entre adolescentes. La limitación del ocio saludable y la promoción deun estilo de vida individualista son consecuencias adicionales. Mediante este estudio exploratoriose recogieron testimonios de ocho jóvenes, se destaca la necesidad de considerar sus experienciaspara mejorar el entorno urbano. La arquitectura hostil no solo afecta a grupos vulnerables, comopersonas sin hogar, sino que también mina el Derecho a la Ciudad de toda la población. Los hallazgossubrayan la importancia de escuchar a los jóvenes para revitalizar el espacio público, promover lainclusividad y crear una ciudad más igualitaria y solidaria.

The stay-green character is a crucial trait linked to delayed leaf senescence, which enables the plant to continue photosynthetic activity for an extended time under early and terminal drought. Reduced water availability causes early leaf senescence, lower chlorophyll content and eventually poor yield in maize. The objectives were to quantify the effects of irrigation regimes, nanocomposite levels physiological parameters, yield attributes and yield of maize. The main plot treatments comprised of well irrigated and withheld irrigation, while the sub plot treatments consisted of different nanoparticles viz., ZnO, MnO, (ZnO + MnO), TNAU nano revive and ZnSO4 + MnSO4. The results revealed that higher dry matter production (5282 and 9891 kg/ha), leaf nitrogen (44.28 and 39.97), grain filling rate, grain filling duration (34.44 days), green leaf area (92.50%) and proline content (0.59 and 1.28 mg g -1) were recorded at tasseling and grain filling stage, respectively under well-irrigated conditions. Foliar spraying of ZnO (100 ppm) and MnO (20 ppm) nanocomposite, registered higher root biomass (24.21 and 32.11 g/plant), leaf nitrogen (44.6 and 39.1), dry matter production, green leaf area, lowest proline content which ultimately resulted in a higher number of cobs/plant, number of grains row/cob, number of grains/grain row, test weight (1000 grains weight), shelling percentage, crop water use (18.79 kg/ha/mm), grain yield (8.20 t/ha), stover yield (12.2 t/ha) and benefit cost ratio of 2.4. Thus, it could be concluded that well-irrigated condition followed by foliar spray with ZnO (100 ppm) and MnO (20 ppm) registered higher growth, yield attributes, yield, and economics.

Ti/IrO2–Ta2O5 coated anodes were widely used in the production process of aluminum foil that is vital raw material for high-performance electronic components, exhibits excellent service durability in sulfuric acid medium, but its lifespan is significantly reduced when used in ammonium citrate neutral electrolyte. The evolution of constant current accelerated lifetime process of Ti/IrO2–Ta2O5 anodes in 100 g/L ammonium citrate aqueous solution was systematically studied. The corrosion mechanism was revealed by physical characterization and electrochemical measurements. During electrolysis, IrO2 was gradually dissolved due to the interaction of IrO2 coating and the electrolyte. Consequently, the corrosion mechanism of the compact IrO2–Ta2O5 coating is the effect of substantial dissolution of the active components.
