Authors: Ammar A. S. M. , Hegab K. K.
Published: February 2025

Flat bread is considered a staple food worldwide and especially balady bread in Egypt and the Middle East region. The most common flat bread types produced all over the world, contents, used leavening agents, properties, and countries were reviewed. Also, balady bread ingredients, formula, preparation, dough rheology, baking conditions, as well as physical characteristics, color attributes, sensory evaluation, and freshness or staling retardation of loaves were presented. Flat bread (balady bread) is processed from attened dough of wheat our, sodium chloride, water, and yeast and is often served freshly baked and produced in both bakeries and homes. The main features of a balady bread oven, such as composition, construction, dimensions, fuels, emissions, and its effect on the environment and energy consumption, were also mentioned. The common specifications and general design of a balady bread industry oven in Egypt on a commercial scale were presented as follows: Oven length could be more or less than 600 cm depending on available space in the baking building. Also, oven width could be more or less than 90 cm, depending on the needed productivity of bread per hour. To “keep the environment, minimize heat losses, maximize quantity and quality of production, and assure economic visibility,” the determination of oven dimensions, selecting construction materials and transmission systems must be done by oven designers using the oven general model.

Indonesia produced 56.54 million tons of paddy (Oryza sativa) dried grain in 2018, with rising demand leading to increased production of by-products such as rice bran. Rice bran, a nutrient-rich by-product, contains high levels of dietary fiber and bioactive compounds with notable anti-cholesterol and anti-diabetic properties. Numerous in vitro and in vivo studies highlight the antioxidant capabilities of rice bran, mainly due to tocopherol, γ-oryzanol, and β-carotene, which function as primary and secondary antioxidants. Effective extraction and fractionation techniques can isolate these antioxidants from rice bran. Cultivation practices significantly impact the nutritional composition of rice bran. The nitrate reductase enzyme (NRA) test can assess growth conditions, which may reflect metabolic activity in paddy plants. Enhanced dietary fiber components (hemicellulose, cellulose, and lignin) and niacin levels make rice bran a promising alternative nutrient source in Indonesia, where unhealthy lifestyles are prevalent. With Indonesia’s significant rice production and bran demand, processed rice bran products hold substantial potential as functional foods for routine consumption, promoting a healthier diet and aiding in prevention of degenerative diseases.

Madalyonun Öteki Yüzü: Toplu İş Sözleşmesinin İşveren Tarafı Olarak Sendikalar
Authors: Göktaş Naim
Published: February 2025

Türkiye’de çalışma ilişkilerinin başat özelliklerinden biri sendikasız ve toplu iş sözleşmesiz çalışmanın yaygınlığıdır. Literatürde, bu sorunun nedenlerini farklı yönlerden incelemiş pek çok çalışma mevcuttur. Ancak sendikaların bünyesinde istihdam edilen işçilerin çalışma koşulları hakkında oldukça az sayıda çalışma bulunmaktadır. Bu çalışmada ise literatürde üzerine yeterince çalışma yapılmamış, sendika işçilerinin sendikal haklardan ne düzeyde faydalandığı sorusuna yanıt aranmıştır. Bu soruya yanıt vermek için çalışmada, sendikal hakların temel parçalarından birini oluşturan toplu iş sözleşmesi hakkına sendika işçilerinin yeterince sahip olup olmadığı araştırılmıştır. Hangi işçi sendikasının işveren olarak toplu iş sözleşmesinin tarafı olduğu, “madalyonun öteki yüzüne” odaklanan bu araştırmada açığa çıkartılmıştır. Çalışmada, sendika işçilerinin kapsamı altına girdiği 10 nolu Ticaret, Büro, Eğitim ve Güzel Sanatlar İşkolu ile 18 nolu Konaklama ve Eğlence Yerleri İşkolu bünyesinde bağıtlanmış toplu iş sözleşmeleri mercek altına alınmıştır. Yöntem olarak ise işkolu barajını geçen ve bu nedenle azımsanmayacak seviyede ekonomik güce ulaşan işçi sendikalarının kurumsal internet siteleri incelenmiş ve ilgili sitelerdeki haber arşivleri taranmıştır. Ayrıca, basın kuruluşlarında yer alan konuyla ilintili haberlerden de yararlanılmıştır. Araştırma sonucunda, sendika işçilerinin büyük çoğunluğunun toplu iş sözleşmesi hakkından yoksun olduğu tespit edilmiştir. Bu yönüyle sendika işçileri diğer işçilerle benzeşmekte ve işveren olarak işçi sendikaları diğer işverenlerden olumlu anlamda ayrışmamaktadır.

Background and Aim: Sudden Sensorineural Hearing Loss (SSNHL) is characterized by a sudden decline in auditory function. While traditional treatments like corticosteroids focus on facilitating hearing recovery, emerging therapies, such as intratympanic platelet-rich plasma (PRP), have demonstrated potential in improving treatment outcomes.This study aimed to evaluate and compare the effectiveness of intratympanic PRP injections and intratympanic steroid therapy in the treatment of SSNHL.

Methodology: After receiving approval from the IEC, 100 patients diagnosed with SSNHL were randomly assigned to two groups: Group A (PRP) and Group B (steroids). Pre- and post-treatment pure tone audiometry (PTA) assessments were performed on all patients, and the results were analyzed to assess the effectiveness of the treatments.

Results: Both groups demonstrated a statistically significant reduction in PTA values after treatment (p < 0.05). Pre-operatively, Group B had higher PTA values [44.165 (36.900-57.325) Hz] compared to Group A [40.0 (33.3225-48.3) Hz]. Post-treatment, PTA values improved to [30.0 (25.0-40.0) Hz] in Group A and [38.665 (28.3-45.4) Hz] in Group B. While intra-group improvements were significant, inter-group differences post-treatment were not statistically significant (p > 0.05).

Conclusion: Intratympanic PRP and steroid therapies are both effective in improving hearing in patients with SSNHL. However, intratympanic steroids remain the preferred first-line treatment. PRP may serve as a secondary option in cases where steroids fail to deliver satisfactory results.
DECOHERENCE-RESILIENT READONLY MEMORY ARCHITECTURE USING QUANTUM TECHNOLOGY

Published: February 2025

Quantum computation draws from theoretical physics, functional analysis, and algorithmic computer science, acting as an interdisciplinary field. The main aim of research in quantum computing is to demonstrate that certain tasks can be completed faster using quantum computers than traditional ones. For this, quantum memory is crucial to developing synchronization tools that coordinate various processes in quantum computers and quantum gates that preserve the identity of quantum states, such as superpositions, and methods to convert preset photons into on-demand photons. Quantum memories are essential for large-scale photonic quantum computing systems, enabling the coherent manipulation, buffering, and retiming of photonic signals. Unlike classical memory, quantum memory allows states to exist in quantum superposition, offering greater flexibility for quantum algorithms than conventional storage systems. While traditional Read-Only Memory (ROM) tends to be slower, quantum computing facilitates the development of novel computer types that operate with qubits as input states, leading to increased storage capacity. This paper proposes a quantum-based ROM (QROM) architecture that utilizes quantum-based binary logic operations and presents an analysis of the systems performance, focusing on heat generation and speed parameters.

The Kawar oasis system constitutes a unique ecosystemlocatedbetween the Tenere erg and the Bilma erg. The oasesmainlyoccupied by date palms are spread out to the east, along the sandstonecliff, of Tertiaryage. The aim of thisstudyis to take stock of the date palm (Phoenix dactylifera L) production system in the Kawar oases. Four municipalities (Dirkou, Bilma, Fachi and Djado) served as study areas. Focus groups and direct observations made it possible to collect data related to the date palm production system. The resultsobtained show that the date palm production system in the Kawar oasesis of the traditional type fromplanting the suckers untilharvest. This speciesplays a key role in the economy of this area. However, itscurrent system does not ensure production in bothquantity and quality. Added to this are the environmental and socio-economicconstraintswhichhamper the sustainable production of dates in the Kawar oases. Therefore, itisnecessary to think about improvingthis system for better production of dates in all the oases of Kawar.

In this work, we have proposed a method for determining the optimum temperature of an n+-p-p+ single-face silicon photocell under polychromatic front illumination using Fossums temperature-dependent diffusion coefficient model Dn (T). The capacitance is therefore determined as a function of temperature and the x and y dimensions of the crystal. The optimum temperature Topt that gives the best short-circuit capacitance is determined from the profile of the logarithm of capacitance versus the logarithm of temperature for different grain sizes.
Demographic risks in the context of a full-scale war in Ukraine
Authors: Posheliuzhnyi Vadym
Published: February 2025

The article examines the impact of the full-scale war initiated by the russian federation on demographic risks in Ukraine. The full-scale war has led to significant changes in the country’s demographic structure, including a sharp decline in the birth rate and an increase in the mortality rate, exacerbating the demographic crisis. The study aims to identify the main demographic risks caused by the war and assess their long-term impact on Ukraine’s socio-economic development. The object of the study is demographic processes in the conditions of the full-scale war. The methodological basis is the demographic analysis of changes in population size, birth, and mortality rates. In 2022, Ukraine’s population was 44.07 million people, but after two years of war, this figure decreased by 15.05%, reaching 37.44 million by early 2024. The birth rate dropped to 5.5‰, and the fertility rate decreased to a critically low level of 0.9 in 2024, one of the lowest rates in the world. Regarding mortality, despite the active hostilities, the mortality rate paradoxically decreased in 2022–2024 compared to previous years (17.1‰ in 2021), likely due to the population reduction caused by mass migration and difficulties in data collection. According to the UN, a total of 22,594 civilians were killed due to military actions, although the actual number of casualties could be much higher. The results indicate a deep demographic crisis that requires urgent government action to stabilize the situation and restore demographic potential. The study's practical significance lies in the potential use of the results to develop government programs to support the birth rate, reduce mortality, and ensure social development in the post-war period.
THE SEARCH FOR THE FOUNDATIONS OF THE AESTHETIC AS EXPERIENCED IN THE PHENOMENOLOGY OF V. SHAPP AND K. STAVENHAGEN
Authors:   Altai State University, POPOV EVGENY
Published: February 2025

The article evaluates the search for the foundations of the aesthetic. In comparison with some positions of analytical and receptive aesthetics, the features of the phenomenological aesthetics of two outstanding students of Husserl—Wilhelm Schapp (1884–1965) and Kurt Stavenhagen (1884–1951) are revealed. The orientation and necessity of searching for aesthetic grounds for these thinkers lies in the possibilities of deviation from the well-known principle of transcendence in the aestheticization of the world of things and the surrounding reality as a whole. For Schapp and Stavenhagen, manifestations of the phenomenological manifestation of the world of things through the experience of being are important—aesthetic. In classical aesthetics, the aesthetic is a certain level of reflection in the sensory-emotional perception of objects from the world of things. As established in the article, Schapp and Stavenhagen propose to identify the aesthetic as the experiential. At the same time, their joint position and beliefs of representatives of receptive aesthetics differ in terms of differentiating aesthetic as an experienced and aesthetic experience as such. The article presents some arguments regarding this orientation in the conceptualization of the aesthetic. The category of aesthetic, interpreted by philosophers as experimental, is revealed through the prism of the correlation of the key concepts of phenomenology—the subjective and the subjective. In this case, the aesthetic is thought of as subjective-subjective, expressed in human individual experience. It was found that Schapp and Stavenhagen, overcoming the inertia of phenomenology and philosophy of history in their theory, evaluated the historicization of the world of things in the aesthetic aspect. Thus, they search for the foundations of the aesthetic in three directions: (1) in the exposition of the subjective/subjective; (2) in the ratio of experience and “quasi-experience”; (3) in defining the boundaries of the experienced existential and experienced social. These directions have opened up the possibility of identifying the aesthetic not as a response to the attributive world of things and not as a given of its aestheticization, but rather as a condition for experiencing being as a result of individual experience. It is concluded that the search for aesthetic grounds for Schapp and Stavenhagen marked a new frontier in phenomenological aesthetics.
PHENOMENOLOGICAL ASPECTS OF GERNOT BÖHME’S AESTHETICS OF ATMOSPHERES
Authors:   National Research University ITMO, IAKOVLEVA LIUBOV
Published: February 2025

This article examines the phenomenon of atmosphere in the aesthetics of the German philosopher Gernot Böhme. It explores the connection between his ideas and those of Hermann Schmitz’s “New Phenomenology” and Martin Heidegger’s ontology. The atmosphere is analyzed through Schmitz’s concepts: the space of human corporeality, and the categories of “contraction” (Enge) and “expansion” (Weite)). Key points of Schmitz’s phenomenology are identified: the absolute space of the felt body, its independence from geometric space; the description of the body's dynamics through bodily impulses and vectors of “contraction” (Enge) and “expansion” (Weite)); the critique of the internal arrangement of feelings; the understanding of feelings and atmospheres as external “forces.” Böhme illustrates illustrated this concepts using the example of the sublime atmosphere in the temple space. Through light and shadow, silence and lines, the atmosphere of the sublime is created. It captivates, astonishes, and directs human corporeality towards spaciousness, providing a perception of the dynamics of human corporeality. Böhme’s description of the atmosphere includes the problem of the subject perceiving the atmosphere. The phenomenon of atmosphere is understood based on the concepts of mood and disposition of a person, derived from Martin Heidegger’s concept of Dasein. Mood is revealed in two ways: as the attunement, the tonality of a person’s own place, and as the tonality of the places in which they reside. It is concluded that perceiving the atmosphere means perceiving the mutual attunement between a person and the world. The final point is the analysis of the concept of ecstasies in Böhme’s aesthetics. The transition from Schmitz’s concept of semi-things to the problem of ecstasies is shown. Ecstasies in Böhme’s aesthetics describe a special space where various qualities of things spread. The radiance of light, the filling of the space with color, the play of light and shadow, the weight of sound—these qualities create an atmosphere. The mood of the place is created by the manifestation of these things, their “resonance,” giving a special aesthetic to the space. It is concluded that the perception of atmosphere includes: the perception of the place of the living body, affected by the mood of the place; the perception of one’s own relationship to the place, the world, and oneself; the perception of how the place reveals its own resonance and mood through the ecstatic properties of things and their ability to fill the entire space.
PHENOMENOLOGICAL ANALYSIS OF BODILY EXPERIENCE IN AESTHETIC STUDIES
Authors:   HSE University, SUKHANOVA OLGA ,   Institute of Scientific Information for Social Sciences of the Russian Academy of Sciences
Published: February 2025

The article considers the trend characteristic of contemporary aesthetic practices, which is connected with the shift of attention to the subject’s corporeality and its mutual influence with the environment, to performativity and active involvement of the subject. The purpose of this review is to analyze the highlighted trend from the perspective of phenomenological philosophy. This will require showing the initial closeness of aesthetic experience to the phenomenological method and the ontological and epistemological grounds for it. The paper will consider the transition from the traditional Kantian understanding of aesthetics as “disinterested” contemplation and the corresponding reflection of this process in the theory of cognition to another model. For this purpose, it is proposed to turn to the theory of “performative turn” proposed by Fischer-Lichte, which demonstrates the irrelevance of hermeneutic and semiotic approach for analyzing aesthetic experience in the modern sense. The article considers the phenomenological approach of J.-L. Marion in its applicability to the analysis of modern aesthetic practices oriented to the radical transformation of the subject. It also suggests tracing the line of criticism of “opticocentrism” in film studies. The cinematic experience is analyzed on the basis of its multisensoriality, as well as the embodiment of the subject and its placement in the environment. For this purpose, the author of the article refers to the theory of M. Merleau-Ponty and its further development in the theory of enactivism. It is concluded that the search for a strategy to reduce the distance between subject and object can be realized in the aesthetic experience, in which subject realizes one's own incorporation to the world. The phenomenological method becomes a tool for analyzing this experience.
PHENOMENOLOGICAL ANALYSIS OF MUSICAL MEANING ON THE MATERIAL OF ROCK MUSIC
Authors:   Lomonosov Moscow State University, KOSILOVA ELENA
Published: February 2025

The article deals with the phenomenological analysis of music perception on the material of rock songs. The structure of a song is simpler than the structure of a classical piece of music, but all the results are valid for any music with appropriate complication. “Listening device”—a computer program that translates sounds into musical notation - perceives individual sounds. But the musical consciousness understands the specific musical thought. It groups sounds into motifs and phrases. F. Tagg introduces the concept of “museme”—a unit of musical meaning. Musemes have meaning only for the understanding consciousness. Musemes of different levels include motifs and phrases, metric signature, rhythm, and the structure of the whole work. In a melody there may be “key sites” in which the concentration of musical thought is maximized. They are constituted by musical consciousness and are largely subjective. The understanding of a musical work takes place in time, and this allows the consciousness to mark out a segment of time, to arrange the intelligible structure in it. A melody is a meaningful whole that has its own logic of unfolding. It encompasses a segment of time and transforms it into something stationary. Melody can be represented in the form of a scheme. The subject of music is the compression of time into such structures. An interesting example of musical perception is psychedelic rock. When listening to psychedelic music, the constitutive activity of consciousness is reduced and an altered state of consciousness occurs. The horizon of meaning narrows, the protention disappears. Here we should recall the notion of “saturated phenomenon” introduced by J.-L. Marion. The saturated phenomenon does not allow for constitution and assimilation. Psychedelic music modifies the horizons of future meanings. The article concludes with a question about computer music: will it make sense to us? So far there is no unequivocal answer to this question.
THE AGE OF THE SYSTEMIC IMPERATIVE. A PHENOMENOLOGICAL DIAGNOSIS OF SOCIAL RESPONSIBILITY
Authors:   Free University of Bozen-Bolzano, DE GENNARO IVO , LÜFTER RALF ,   Free University of Bozen-Bolzano
Published: February 2025

We provide a phenomenological interpretation of the rise of responsibility as a key concept of contemporary ethics. If we consider the philosophical tradition at large, responsibility has emerged as a concern, or even the center of attention, of ethical reflection only in relatively recent times. How can we account for this emergence? We argue that today’s pervasive concern with responsibility envisages a responsibility that is constitutively “social,” and that the thus understood responsibility traces back to a more original trait of sense, which presently informs our relation to the world. This trait we call “responsive.” Hence, our contention is that, when in contemporary ethical discourse we speak of (social) responsibility, the latter has a fundamentally responsive character. The responsive character of the contemporary concept of responsibility is related to the appearance of a new kind of imperative, which we call “systemic.” Originating from the unique imperative of “the system of universal existence,” systemic imperatives have the form of factual urgencies, which, while demanding an urgent and effective response, exclude the scope of what traditional ethics conceives as the perfectibility of beings. Our diagnosis of responsive responsibility in the horizon of the systemic imperative is guided by the phenomenon of “original responsibility”, which we obtain from Heidegger’s hermeneutic phenomenology. “Original responsibility” refers to the relation between man’s being and being itself. The form of this relation is that man’s being consists in a (needed) response to being itself. Based on this hermeneutic framework, we show how the kind of threat which informs the systemic imperative (here exemplified by Hans Jonas’s “ecological imperative”) holds in store the expectability of a new “perfection” of beings.
Caracterização fenotípica e diversidade genética de ovinos da raça morada nova variedade branca
Authors:   , Nunes Samuel Freitas
Published: February 2025

A partir da falta informações técnicas sobre o padrão racial da variedade branca de ovinos da raça Morada Nova e da situação de risco em que a mesma se encontra, o presente estudo objetivou fornecer informações para subsidiar a seleção e a manutenção da variabilidade genética a partir de dados de morfometria, índices zootécnicos, imagens e estudo molecular com uso de marcadores de SNPs para conhecer de forma mais profunda a estrutura e a diversidade genética dos rebanhos. Os animais do fenótipo branco da raça Morada Nova são dolicocéfalos (Ice = 41,9), com boa capacidade torácica (IT = 60,2), desenvolvimento corporal médio (IC = 0,80) e garupa quadrada (IP = 105,8), possuem mucosas, cascos e pele despigmentados ou parcialmente despigmentados e características morfológicas (IRCG = 1,0; ICC1 = 0,6; ICC2 = 0,5; IPT = 32,4; IPL = 30,5 e IRPT = 1,3) que indicam aptidão para a produção de carne. Embora existam algumas variações destas características entre as populações, grande parte pode ser explicada por fatores ambientais, principalmente por diferenças nos manejos nutricionais e reprodutivos. Dentre as variáveis relacionadas, as medidas cefálicas são as que apresentam o maior poder de diferenciação entre os animais. A endogamia entre os indivíduos (FIS < 0,05) está baixa, em contrapartida a diferenciação genética entre a maioria das subpopulações estão baixas (FST < 0,05), resultados que ressaltam a necessidade de se pensar estratégias e fomento para gerir esta população.
Avaliação das condições de cultivo e criopreservação sobre o estabelecimento de linhagens fibroblásticas de onças-pintadas, panthera onca (linnaeus, 1758)
Authors:   , Silva Maria Bárbara
Published: February 2025

O quantitativo populacional cada vez mais reduzido de onças-pintadas, associado à sua importância ecológica, tem resultado no desenvolvimento de estratégias que promovam a sua conservação. Nesse sentido, células somáticas derivadas da pele destes animais podem ser empregadas para essa finalidade, seja na produção de embriões clones, na obtenção de células induzidas à pluripotência e nos estudos genéticos da espécie. Para tanto, o estabelecimento adequado destas amostras é etapa inicial para essas aplicações. Portanto, o objetivo do presente estudo foi avaliar os danos gerados pelas condições de cultivo in vitro e criopreservação sobre o estabelecimento de cinco linhagens fibroblásticas derivadas de onças-pintadas adultas. Assim, fragmentos da pele da região auricular apical de uma fêmea e quatro machos foram cultivados in vitro para a obtenção das células somáticas. Inicialmente, para a identificação do tipo celular, células foram confirmadas como fibroblastos após análise morfológica e de imunofluorescência, e as cinco linhagens (um animal/uma linhagem) foram submetidas a dois experimentos. No primeiro experimento, células foram avaliadas em diferentes passagens do cultivo (primeira, terceira décima) para viabilidade, metabolismo e atividade proliferativa. No segundo experimento, células criopreservadas foram avaliadas quanto a viabilidade, metabolismo, atividade proliferativa, níveis de espécies reativas de oxigênio (EROs), potencial de membrana mitocondrial (ΔΨm) e apoptose após descongelação em uma, três e dez passagens de cultivo. Células não criopreservadas foram utilizadas como controle. O cultivo in vitro após a primeira (26,1 h ± 4,9), terceira (22,9 h ± 1,6) e décima passagem (22,8 h ± 3,7) e criopreservação (30,0 h ± 1,4) não afetaram a atividade proliferativa. Além disso, nenhuma diferença foi observada para a viabilidade após a primeira (98,9% ± 0,8), terceira (92,5% ± 6,2), décima (95,7% ± 1,4) passagem e criopreservação (73,2% ± 9,8). Contudo, células cultivadas até a décima passagem (49,0% ± 3,3) e criopreservadas (32,7% ± 2,8) reduziram seu metabolismo. Adicionalmente, células criopreservadas mostraram em unidades de fluorescência arbitrárias altos níveis de EROs (1,4 ± 0,1) e ΔΨm alterado (0,9 ± 0,0), quando comparados às células não criopreservadas (1,0 ± 0,1 e 1,0 ± 0,2). Finalmente, células criopreservadas e cultivadas após dez passagens reduziram a atividade proliferativa reduzida (45,1% ± 12,0) e número de células viáveis (30,4% ± 5,7), quando comparadas as células criopreservadas e cultivadas após uma e três passagens. Em conclusão, fibroblastos viáveis podem ser estabelecidos a partir da orelha de onças-pintadas e que embora essas células não tenham mostrado alterações na viabilidade e atividade proliferativa, elas sofrem danos durante um longo cultivo e criopreservação nas condições estudadas.

Published: February 2025

A instalação de sistemas eólicos conectados à rede elétrica no Brasil, principalmente na região Nordeste, vem expandindo exponencialmente, e para avaliar a viabilidade de construção de um parque eólico, umas das principais informações da região é o vento, e através de artifícios matemáticos é possível prever e estimar seu potencial. O presente trabalho propõe analisar e aplicar os dados de uma estação meteorológica automática em uma Rede Neural Artificial (RNA) Autorregressivo Não Linear (Nonlinear Autoregressive - NAR). O estudo contribuirá para melhorar a eficiência dos parques, bem como a manutenção dos aerogeradores e ainda colaborar com a distribuição da matriz elétrica no país, uma vez que com a informação prévia do vento será possível realizar agendamento para paradas programadas visando a manutenção dos parques e em épocas de maior produção energética obter um bom escoamento dessa energia. Para o estudo da previsão do vento, foram utilizadas as bases de dados das estações de medição automáticas do Instituto Nacional de Meteorologia (INMET), que tem como finalidade a coleta de informações de campo, como velocidade do vento, temperatura, direção do vento e umidade em determinadas alturas. A partir do histórico dessas variáveis, que foram coletados online nestas bases de dados, foi possível treinar uma Rede Neural Artificial e traçar o perfil do vento na região nordeste do Brasil, para as épocas do ano. Para isto, foi adotada a seguinte metodologia, primeiramente, com o apoio do software Excel da Microsoft®, foi aplicado o tratamento dos dados utilizando técnicas estatísticas, e no segundo momento os dados tratados foram submetidos a uma RNA-NAR. É possível perceber que a RNA-NAR obteve boa resposta quando implementada com os dados do INMET, apresentando uma correlação acima de 90% dos casos e um erro quadrático médio abaixo de 2,0 na predominância das redes testadas. De acordo com os resultados, é conclusivo que as redes NAR são opções viáveis para previsão do vento

O objetivo deste trabalho foi estudar amostras dielétricas de soluções sólidas de ferrita de lantânio (LaFeO3 ou LFO) e titanato de cálcio (CaTiO3 ou CTO): LFO(1-m)CTO(m), para diferentes frações de massa m, como ressoadores para antenas ressoadoras dielétricas operando no modo HEM11δ na faixa de frequências de micro-ondas, devido à escassez do estudo desses materiais nessa faixa. Para isso foram calculadas as frequências de ressonância teóricas das amostras com base nas equações disponíveis na literatura e foram realizadas as medições de seus parâmetros dielétricos e de antena para a observação do comportamento das amostras como radiadores de energia eletromagnética; logo após, foram realizadas simulações para a comparação com os resultados medidos. Para as DRAs, foi possível obter frequências de ressonância nas bandas C, S e L do espectro de frequências, possuindo diagramas de radiação broadside e direcionais com bom ganho, além de bom casamento de impedâncias, operando adequadamente. Ademais, foi obtido que com o aumento da fração de massa m a frequência de ressonância tende a reduzir seu valor e que antenas com fração de massa menor tendem a ser mais eficientes. Também foi possível observar a rotação anti-horária do padrão de impedâncias na carta de Smith para alguns dos ressoadores em dois diferentes setups

Superfícies Seletivas em Frequência (FSS) vem sendo utilizadas nas mais diversas aplicações,
atuando como filtros espaciais para ondas eletromagnéticas. Tais estruturas podem ser
empregadas na melhoria do conforto térmico em ambientes, por meio do bloqueio na troca de
calor entre ambientes externos e internos. Também podem ser aplicadas na melhoria da
segurança e qualidade de sinal em redes de comunicação sem fio, em ambientes indoors.
Logo, houve um aumento nos estudos e desenvolvimento de FSS aplicadas em superfícies de
vidro, para o desenvolvimento de janelas capazes de realizar a filtragem de sinais. Assim, este
trabalho tem o objetivo de realizar o estudo e o desenvolvimento de uma FSS com substrato
de vidro, que realize o bloqueio de sinais na frequência de 2,4 GHz, seguindo os padrões
IEEE 802.11b/g, para aplicação em ambientes de comunicação indoor. Para projetar a
estrutura com desempenho satisfatório, foi realizado um estudo de alguns parâmetros
eletromagnéticos do substrato de vidro e o efeito do tratamento térmico nos mesmos. Foram
construídas duas FSS, uma com substrato de vidro comum e outra com substrato tratado
termicamente. O elemento escolhido foi à espira quadrada simples, sendo a mesma projetada
por meio do Modelo de Circuito Equivalente (MCE), modelada e simulada usando-se o Ansoft
software High Frequency Structure Simulator (HFSS®). As estruturas foram medidas por
meio do método de transmissão e reflexão no espaço livre. As FSS apresentaram desempenho
satisfatório, atuando como filtro rejeita-faixa no intervalo especificado para a maioria dos
ângulos de incidência, sendo observada uma melhora da estabilidade angular da FSS após o
tratamento térmico do substrato, com exceção para o ângulo de 10° na polarização vertical. A
estrutura proposta apresenta potencial para aplicação na melhoria da qualidade do sinal e
segurança dos usuários de redes WLAN

Authors: Caerols Mateo Raquel
Published: February 2025

Las sociedades del conocimiento, entendidas en su origen como modelos transformadores para los retos de un mundo tecnológico y de cambios vertiginosos, parece que están generando colapsos en las propias bases de su modelo. La necesidad de buscar y conformar otros modelos nos obliga a poner la mirada en distintos enfoques, enfoques integrales y sistémicos que nos lleven más allá de la tecnociencia.
El origen etimológico de la palabra saber, que es el mismo que la palabra sabor y que, por tanto, fusiona el conocimiento inteligible y la experiencia sensible, es el leitmotiv para realizar un recorrido conceptual a partir de autores referentes en estas problemáticas, en el intento de conformar los lineamientos de una sociedad del saber a partir del abordaje sistémico de diseño, arte y ciencia.

Although Malaysia's poverty rate has decreased, there are still people who suffer from extreme poverty, especially in rural areas. The agropolitan project aims to eradicate extreme poverty and accelerate development in rural areas. The achievements of agropolitan projects are evaluated through the extent to which they help participants to get out of extreme poverty and are measured using Poverty Line Income (PLI). A study using the Sustainable Livelihood Framework (SLF) was conducted at the Gahai Agropolitan Project, Lipis, Pahang, and involved 45 participants. Research data was obtained through the distribution of questionnaires and analyzed using Statistical Package for the Social Sciences (SPSS) version 22 software and Microsoft Excel. Studies indicate that the Gahai Agropolitan Project can eradicate poverty and contribute to sustainable livelihoods. From the aspect of sustainable living, the study results show that the participants of the Gahai Agropolitan Project experience high vulnerability. Moreover, asset ownership analysis reveals that the Gahai Agropolitan Project participants have good asset ownership.

Understanding the relationship between urban design and physical activities is crucial. Studies have identified three key neighbourhood environment indices that enhance walkability. This research investigates the influences of these indices on residents’ walkability to community facilities in two neighbourhoods in Penang Island, Malaysia. Using geographic information system (GIS) technology, we analyse the effect of the built environment on walkability through buffering and thematic map analyses. Pulau Tikus features medium- and low-density housing with enriched community facilities, whilst Tanjung Tokong has a higher residential density, more road intersections and more diverse housing options. Findings indicate that Pulau Tikus offers better amenity accessibility, whilst Tanjung Tokong’s high-rise residential buildings and diverse housing types enhance walkability. This study highlights the relationship amongst residential density, road intersections, mixed land use and walkability in two residential neighbourhoods. Higher residential density and more road intersections increase walking activity, whilst mixed land use further influences resident mobility patterns. These insights can aid urban planners in designing more walkable, liveable and sustainable neighbourhoods.

Cultural tourism is an expanding sector of the global travel industry, with tourists seeking genuine and immersive experiences that connect them to the cultural heritage of the region. Malaysia’s cultural museums enable visitors to learn about the country’s diverse ethnic groups, religious practices, historical events, and artistic accomplishments. This proposed study aims to fill the existing research gap by conducting a comprehensive evaluation of tourist behavior in Malaysia’s cultural museums. The research employs a quantitative method by collecting data through surveys from 381 respondents. The statements in the survey embody various elements, including education, escape, aesthetics, and entertainment. The results indicate that the aesthetic element is the most valued by the respondents during their visit, while the escape element is the least valued. The majority of the respondents belong to a younger age group, which tends to appreciate aesthetics the most. Almost one-third of the respondents visited the museum for work-related reasons, which explains why the escape element was the least appreciated. Historically, museums have evolved over time, with the earliest known as “Cabinets of Curiosities” in the 1500s. Existing museums can begin to incorporate other attractions or offer more activities to make the visit more engaging and enjoyable for visitors.
