Beverages are among the most popular types of products that attract attention of researchers for enrichment with functional ingredients. The introduction of probiotics into the food matrix can increase the usefulness of food products, including beverages. However, probiotics are extremely sensitive to extreme environmental conditions, which significantly limits their ability to survive in food. The aim of the research is to establish an effect of encapsulation on the preservation of bifidobacteria in an enriched juice-containing beverage. Capsules from sodium alginate were used to protect probiotic microorganisms (bifidobacteria of six strains in the symbiotic starter) from unfavorable conditions of the environment of the food system and the gastrointestinal tract. The capsules were obtained by the drip method. The stability of the capsules was determined under different conditions. Their solubility in water and at pH values typical for the stomach (1.1–1.6), small intestine (7.8–8.2), and large intestine (8.0–8.5) were studied. The tests were carried out upon keeping in buffer solutions for 15 and 30 min. In addition, the stability of the capsules in apple juice with a pH of 3.82 when stored at 4±1°C for 7, 14, 21, and 28 days was assessed. Capsule losses during heat treatment were analyzed. The amount of bifidobacteria extracted from the capsules after mechanical destruction with their subsequent inoculation on the GMK1 medium was also monitored during juice storage. The results of the studies showed that the greatest destructive effect was observed in an acidic environment typical for the stomach, where losses amounted to 47.4% after 30 min. Capsule losses at pH values typical for different parts of the intestine ranged from 25.3 to 30.9%. The selected food system, apple juice, turned out to be a less aggressive environment for the capsules, in which the destruction of capsules was 8.7% after 28 days of storage. Capsule losses under the selected juice pasteurization modes ranged from 60.17% during processing for 10 minutes at 85°C to 67.42% during juice processing for 30 minutes at 98°C. The differences were statistically significant (p≤0.05). Thus, using the obtained data, it is possible to predict the total loss of capsules and probiotic microorganisms during the digestion and storage of the product and inoculate the required amount to impart probiotic properties to the product. The research has development prospects taking into account the possibility of varying the taste and aroma properties of both the food system and the capsules.

Giant salamanders are the world’s largest amphibians and keystone predators in riverine ecosystems where they face global declines. Identifying environmental variables influencing their distribution is, therefore, an essential step for their conservation. This study aims to assess the current habitat suitability and distribution of the Japanese giant salamander (Andrias japonicus) and to predict changes under future climate scenarios. We used species distribution models (SDMs) over a 282,916 km² area, including 477 high-resolution occurrence data of giant salamanders and seven remote-sensing environmental predictors (climatic, topographic and land use). We projected the prediction maps, identified the most contributing variables and calculated the shifts of suitable areas for three periods (2050, 2070 and 2090) under projected climatic conditions. Climatic variables highly contributed to the distribution of giant salamanders (76% of the total), with preferences for areas with moderate precipitations during cold and wet seasons and mild summer temperatures. A moderately steep surrounding environment was favourable for salamanders, whereas the land-use variables had less influence. Future climate predictions indicate a major decrease of suitable areas. Altogether, our results highlight the habitat preferences of giant salamanders at a broad scale and the negative impact of climate change on future suitable areas. These findings provide important steps for upcoming conservation actions for this threatened species in delineating favourable distribution ranges and priority areas that should be directly affected by climate change. Finally, they emphasise the need for new research at a fine scale on disturbances to the aquatic habitat to enhance the conservation of giant salamanders.

We used a species distribution model (MaxEnt), high-resolution occurrence data and remote sensing data (climatic, topographic and land use) to identify suitable habitats for the Japanese giant salamander in Japan.

The most suitable environments for the Japanese giant salamander are located both within and beyond its current distribution range, with the ‘Japanese Alps’ forming an impassable natural barrier.

Among the variables studied, precipitation of the warmest quarter, precipitation of the coldest quarter, mean temperature of the warmest quarter and mean temperature of the wettest quarter were the most important environmental predictors of the species’ distribution.

Climate change is expected to severely reduce the potential suitable geographical areas for the Japanese giant salamander in the future.

The present work calls for new surveys based on the projected maps to improve the mapping of salamander distribution and to focus on ecological features and threats at the aquatic habitat level to understand the risks to their populations.

Letters are one of the most common forms of communication in people's daily lives. Activities related to letters are commonly referred to as correspondence. Duta Wacana Christian University Yogyakarta is one of the institutions where correspondence activities are still carried out for internal organizational purposes Initially, correspondence activities at UKDW were still done manually by using physical letters, which were sent to the intended address by asking people to deliver them directly. However, the correspondence process is becoming less efficient. The process that must be passed is quite long, so it takes a lot of time and energy.
This incoming and outcoming lettters management website was designed to help and facilitate UKDW employees in carrying out correspondence activities, which were formerly performed manually, through the use of a website. This research uses design thinking as the design method. The Design Thinking method consists of several steps: Empathize, Define, Ideate, Prototype, and Testing. For the testing phase, the author uses the Usability Testing as a method to evaluate the effectiveness, efficiency, and user satisfaction of the website.
Codebase release 1.0 for DanceQ

Published: February 2025

The complexity of quantum many-body problems scales exponentially with the size of the system, rendering any finite-size scaling analysis a formidable challenge. This is particularly true for methods based on the full representation of the wave function, where one simply accepts the enormous Hilbert space dimensions and performs linear algebra operations, e.g., for finding the ground state of the Hamiltonian. If the system satisfies an underlying symmetry where an operator with a degenerate spectrum commutes with the Hamiltonian, it can be block-diagonalized, thus reducing the complexity at the expense of additional bookkeeping. At the most basic level required for Krylov space techniques (like the Lanczos algorithm), it is necessary to implement a matrix-vector product of a block of the Hamiltonian with arbitrary block-wavefunctions, potentially without holding the Hamiltonian block in memory. An efficient implementation of this operation requires the calculation of the position of an arbitrary basis vector in the canonical ordering of the basis of the block. We present here an elegant and powerful, multi-dimensional approach to this problem for the U(1)U(1) symmetry appearing in problems with particle number conservation. Our divide-and-conquer algorithm uses multiple subsystems and hence generalizes previous approaches to make them scalable. In addition to the theoretical presentation of our algorithm, we provide DanceQ, a flexible and modern – header only – C++20 implementation to manipulate, enumerate, and map to its index any basis state in a given particle number sector as open source software under https://DanceQ.gitlab.io/danceq.

Published: February 2025

This paper aims to analyze the influence of local revenues, unconditional grants, and total population on regional expenditure in six provinces in Sulawesi, Indonesia. Panel data covering the period from 2013 to 2023 were analyzed using the fixed effects model (FEM) using the STATA software. The results show that local revenue has a significant positive effect on regional expenditure (β = 0.366; p-value 0.000 < 0.05), unconditional grant has a significant positive effect on regional expenditure (β = 0.501; p-value 0.000 < 0.05), and total population has a significant positive effect on regional expenditure (β = 1.207; p-value 0.001 < 0.05). The results show considerable regional disparities, with Southeast Sulawesi and North Sulawesi displaying the highest dependency on central funds, while South Sulawesi exhibits relatively greater fiscal independence. These findings highlight the need for policy reforms to strengthen local revenue generation, minimize reliance on central government transfers, and prioritize investments in infrastructure. Such strategies are crucial for ensuring fiscal sustainability, enhanced local autonomy, and long-term regional growth.
La vida en México (1839-1841) de Madame Calderón de la Barca: un análisis de las fuentes documentales empleadas por la autora y sus influencias en el estudio del México decimonónico
Authors: López-García Ana-Belén
Published: February 2025

Travel stories about Mexico in the 19th century have been recognized as one of the most prolific literary genres throughout history. From ancient times to the present there has been a constant interest in leaving in writing the testimony of the places visited, their education, folklore and heritage. Life in Mexico stands out among these works for its ability to transcend initial criticism and for being written by a foreign woman with an Anglican mentality, which represented a challenge in 19th century Mexico. This article analyzes the documentary sources that influenced the author in the creation of her work, as well as those that allowed her to delve into the Mexican society of the time, and that are cited in Life in Mexico. His influences come from reading various publications that addressed the history of Mexico, including the work of the German historian Humboldt, among others. It is important to highlight that the main themes addressed in her writings are supported by printed sources such as periodicals of the time and women’s literary magazines. In summary, Life in Mexico was a set of letters that generated controversies and ambiguities in the perception that the author offered about the country, even in the use of sources that support her work and those that inspired the protagonist to explore Mexico. of the 19th century.
ART EDUCATION AND THE WORLD OF LIFE: MICHEL HENRY ON THE CULTURAL VALUE OF ART
Authors:   Department of Philosophy, University of Prince Edward Island, SCHAEFER MAX
Published: February 2025

A commonplace criticism of Michel Henry’s phenomenology of life is that it denies that the subject’s existence in the world is of any importance to life’s flourishing. Henry’s phenomenological study of art and aesthetics, including his study of the work of Russian art-theorist and painter Wassily Kandinsky, has typically been understood as reinforcing this very position. This paper will argue that those who critique Henry's study of art, and indeed his phenomenology more generally, on these grounds are both right and yet mistaken. They are right in that the flourishing of absolute life does not depend on the subject’s worldly existence. However, they are mistaken in that from the point of view of human beings, the finite subject’s existence in the world, particularly her engagement with the arts, does play a part in the well-being of their life. In support of this position, I will argue that Henry’s study of art and aesthetics reveals that our worldly relationship with art plays a role in educating our feelings, and that this education is vital to the flourishing of the life of finite living beings. Our engagement with art does this, as I will show, by enhancing our attunement to ourselves, others, life, and the world, and in allowing us to experience and understand the world as an expression of life, and as therefore being important to us personally. As further testament to the importance of our worldly engagement with art for life, I will show how, in Henry’s view, our worldly engagement with bad art plays a part in the corruption of life and thereby stunts our emotional growth and leads us to feel increasingly alienated from the world.
SPACE AND TIME IN AN AESTHETIC EXPERIENCE
Authors:   St. Petersburg State University of the Ministry of Emergency Situations of Russia, SHEVTSOV KONSTANTIN , KUKSO KSENIA ,   Herzen State Pedagogical University of Russia
Published: February 2025

The article addresses the experience of depth and volume of space as a key issue of sensory existence and, accordingly, a key issue of aesthetics. In Kant’s philosophy, space and time correlate and oppose each other as forms of external and internal feeling, however, for judging the reality of the world, the possibility of mutual reflection of space and time turns out to be fundamentally important. The depth of space opens up inside this reflection, so it actually becomes an expression of the principle of the real. Depth perception involves many forms of refraction and embedding of internal and external into each other, requiring careful phenomenological analysis, but the main question remains the location of consciousness in space. The experience of such an arrangement is given by a medium, whose role is a part of the body or a fragment of sensual openness to the world, which begins to be perceived as part of the world itself. In our perceptual experience, the distinction of sensory modes of reality (channels of perception) comes to the fore and the selection of one of them as a leader, which allows it to become a carrier of meanings belonging to other modes. The leading channel actually becomes a representative of the holistic experience of sensuality, and its isolation reveals the work of the medium hidden behind the surface of perception. As such a medium, a person acts as an attitude to the eventfulness of the world, a form of openness, which is due to a constant level of tension, mobilization of feeling, support for one sensory mode by another, readiness for perception. The work carried out by the medium leads to the emergence of an image as a form of entry into space and time, in which the sensual presence acquires its integrity. Aesthetic experience returns to the primary phenomenon of the presence in sensuality and the openness of sensuality to time and space, so that sensuality is lived not only as a given, but also as an opportunity for the subject to grow in relation to both himself and the world.
ARTHUR SCHOPENHAUER: PHENOMENOLOGY OF THE BODY AND AESTHETICS
Authors:   St. Petersburg State University, SIDOROV ALEKSEY
Published: February 2025

The main thesis of this article is that Arthur Schopenhauer was the first to formulate clearly the problem of corporeality as an essential problem of philosophical thought. Schopenhauer can be understood as a philosopher and even as a phenomenologist of corporeality. For the first time in the European thought he explicitly describes the relation between consciousness and the body and offers a phenomenological description of the experience of embodiment, bringing his thought closer to M. Merleau-Ponty’s future phenomenology. The article considers the role of the body in the formation of subjectivity as well as the correlation between the concept of body and the concept of will in the structure of Schopenhauer’s philosophy. Both Schopenhauer and Merleau-Ponty understood the body as a key to the experience of the world and to overcoming the object-subject dichotomy. Hence, while Merleau-Ponty welcomes this conclusion, Schopenhauer considers it is a source of pessimistic sarcasm: the will of which I am the materialization is completely indifferent to my individual existence and uses me as material for its meaningless reproduction. The emphasis on corporeality has important intersections with the development of aesthetics in the 18th century. T. Eagleton thus suggests that Schopenhauer’s philosophy makes a crucial contribution to the modernist project of aesthetics by its “implicit” aesthetics, presupposed by the development of the theme of embodiment, to which he attributes the unexpected “comicality” of Schopenhauer’s philosophy, well suited to the interpretation of absurdist art. The article also considers the influence of Schopenhauer’s philosophy on Beckett’s work, which S. Garner interprets through Merleau-Ponty’s phenomenology of the body, proving that their reflections on body and flesh can be correlated with Beckett’s theater where the bodily presence of actors is emphasised.
PHENOMENOLOGY OF LIGHT IN THE AESTHETIC VIEWS OF J. FOSSE ON THE EXAMPLE OF HIS WORK “ANOTHER NAME. SEPTOLOGY I–II”
Authors:   Herzen State Pedagogical University of Russia, MASLIAKOVA ANNA ,   Kyrgyz National University named after Jusup Balasagyn
Published: February 2025

The aim of this article is to study the phenomenology of light, which plays a significant part in the aesthetics of Jon Fosse, the Norwegian writer who was awarded the Nobel Prize in Literature in 2023. According to Jon Fosse, art is not only a way of perceiving the world around us but also a necessary condition for harmonious existence in it, which is most fully reflected in the work “The Other Name: Septology I–II,” first published in 2019. One cannot help but agree that the deep religiosity of the author, who converted to Catholicism in 2013, has had a huge influence on his work. Many hundreds of years ago, the Nativity of Christ illuminated the “darkness” of the pagan world, and the degree of “manifestation” of this “Divine Light” in works of art, according to Jon Fosse, is one of the main criteria for their authenticity. As for “darkness,” it acts as the primary source of light, the very same “Nothing” that from time to time peeks through “Being,” and against the background of which the light “sounds” especially prominently and brightly. According to the concept of the “Septology I–II,” art not only activates the process of self-determination of the individual, who is in continuous dialogue with “others-in-themselves” (the painter Asle and his “alter ego”), but also the work of art as such has its own identity, which is constantly evolving, opening “in-itself-for-us” new facets and shades. Moreover, according to Jon Fosse, the artist’s mission, in the broad sense of the word, is to show people the path to the “Divine Light” in the “tunnel” of quantum uncertainty, especially during transitional periods of history.
THE PREFACE TO THE TRANSLATION OF DRAGAN PROLE’S ARTICLE “EQUALITY OF THE UNEQUAL. PHENOMENOLOGY AND EARLY AVANT-GARDE MOVEMENTS”
Authors:   Herzen State Pedagogical University of Russia, SHEVCHENKOVA ANASTASIA
Published: February 2025

The paper is a translation of an article by D. Prole which examines the difference and the resemblance of the phenomenological project and the early avant-garde movements. Responding to the crisis of the classical in the realms of aesthetics and strict philosophy both phenomena strive for authenticity, approaching it each in their own way: the Dadaists and the Expressionists fundamentally reject all the rationality and oppose academicism, while phenomenologists do not dispute the academic tone of philosophizing, even when they go beyond the Husserlian methodology. Phenomenology absorbs the classical spirit and places it at the heart of modern philosophizing. Exploring the kindship of phenomenology with the early avant-garde, the author focuses on the concept of neutralization, which replaced the concept of negation in the 20th century. Turning to the understanding of neutralization by Husserl, Heidegger, Sartre, Adorno, the author shows that both in the field of the free artistic experiment and within the framework of the strict philosophical discourse, neutralization enables contemporary subjectivity to present itself as a distant individuality. The preface to the translation discusses the possibility of placing phenomenology in a situation of dialogue with the theories and practices of the Russian avant-garde. The similarity of two approaches is evidenced by the examples of the Russian avant-gardists’ appeal to the tradition and their sensory approach to the experience of reality.

Authors: Christophoridis Christophoros , Touloupi Myrto , Bizani Erasmia A. , Iossifidis Dimitri
Published: February 2025

This study investigates the sustainable management and utilization of water resources in the fruit processing industry, focusing on a case study from the EU-funded ULTIMATE project. Conducted in a juice factory in Nafplio, Greece, the primary objective is to explore the recovery of polyphenols from water by-product streams generated during orange juice production. The research aims to evaluate the effectiveness of a mobile wastewater treatment unit in selectively adsorbing polyphenols onto a polymeric resin. The following three extraction methods are compared: conventional solvent extraction, subcritical water extraction (SWE), and supercritical CO2 extraction (SFE). To determine the most efficient extraction method, the polyphenol profiles of the extracts were analyzed using UHPLC-Q-Orbitrap-MS/MS, identifying flavonoids, terpenes, coumarins, and anthocyanins. SFE not only was the most efficient method but provided the most diverse and abundant profile. The research highlights the potential of converting industrial by-products that would otherwise be treated as wastewater, into valuable resources that generate revenue, promote circular economy practices, and enhance sustainability in the fruit and vegetable processing sector. The economic viability of polyphenol extraction is also discussed, emphasizing its significance and impact on various industries. The findings support integrating advanced extraction technologies to maximize resource recovery and minimize environmental impact.

O proposito desse estudo foi avaliar a atividade antimicrobiana do extrato de geoprópolis da
abelha jandaíra (Melipona subnitida Ducke) em Salmonela sp. isoladas de carne bovina e
frango comercializadas no Município de Mossoró/RN como alternativa aos antibióticos. Para
a condução dos experimentos as amostras foram adquiridas na forma de consumidor em 30
estabelecimentos espalhados pela cidade. Foram coletadas 60 amostras, sendo 30 de carne
bovina (coxão mole) e 30 de frango (peito). Para detecção de Salmonela sp. seguiu-se os
procedimentos descritos na instrução normativa n° 62 de 2003. Amostras positivas foram
submetidas a dois testes, ambos usando o método de difusão a disco. No primeiro, foi
avaliada a susceptibilidade aos antimicrobianos de uso clínico e no segundo, as amostras
foram submetidas ao extrato de geoprópolis da abelha jandaíra, diluídos em três
concentrações diferentes (100%, 75% e 50%) a fim de avaliar o seu potencial antimicrobiano,
foram considerados positivos halos ≥ 6 mm. Como resultado obteve-se 18 amostras positivas
para Salmonela sp., 12 (20%) de frango e 6 (10%) de carne bovina. Na avaliação aos
antibióticos de uso clinico os resultados demostraram um índice de resistência de 72% (13/18)
a ampicilina, 11% (2/18) a sulfametoxazol/trimetropim, cefoxitina e amoxicilina/ácido
clavulânico e 6% (1/18) a cefotaxima. 100% apresentaram-se sensíveis a amicacina,
meropenem e clorafenicol, 94% (17/18) a ciproflaxaxino, 89% (16/18) a
sulfametoxazol/trimetropim, cefoxitina, cefotaxima e amoxicilina clavulânico, 83% a
ceftazidima e cefepima e 28% (5/18) a ampicilina, apresentaram ainda reação intermediária a
cefepima e ceftazidima 17% (3/18) e ciprofloxaxino e cefotaxima 6% (1/18). E como resposta
ao extrato de geoprópolis, nas diluições de 100% e 75% os halos mediram em média 8mm e
em 50% apresentaram medida de 9mm. Conclui-se que há necessidade de mais atenção no
controle de qualidade dessas carnes, visto que foi verificado presença de Salmonela sp. em
30% (18/60) das amostras analisadas, bem como resistência das mesmas a alguns antibióticos
testados. Em contrapartida verificamos que o extrato de geoprópolis apresentou-se como uma
alternativa antibacteriana eficaz.

Objetivou-se com esse estudo avaliar as respostas termorreguladoras de ovinos em confinamento na região do semiárido, quando submetidos a inclusão de extrato etanoico de própolis marrom na dieta. Para isso, foram utilizados doze ovinos machos, sem padrão racial definido (SPRD) pesando aproximadamente 22kg, recebendo dieta a base de volumoso e concentrado na proporção de 40:60, a alimentação foi dividida em duas refeições que foram fornecidas às 08h00min e às 16h00min, sendo permitidas sobras de 10% do total fornecido. Os animais foram divididos em dois tratamentos, TC - sem inclusão de própolis e TP - com inclusão de própolis, para o grupo com inclusão de própolis o extrato foi fornecido antes da dieta para que se tivesse a confirmação da ingestão total dos 8ml fornecidos. Os animais foram submetidos a 59 dias de experimento, sendo 14 dias para adaptação e 45 dias para coleta de dados dos parâmetros fisiológicos. Para avaliar a resposta dos cordeiros ao estresse térmico foram aferidos os parâmetros fisiológicos em três momentos, começo, meio e fim do período experimental, iniciando as 7 horas da manhã e finalizando as 17 horas, a cada 120 minutos. Foram observadas a frequência respiratória, temperatura retal, temperatura do ar, umidade relativa e velocidade do vento. Foi observado que, para os animais do grupo controle a frequência respiratória diferiu quando a TA foi inferior a 28ºC e quando foi superior a 36ºC, enquanto que para o grupo própolis houve diferença apenas quando a TA foi inferior a 28ºC. Para os dois grupos não foram observadas diferenças significativas (P<0,05), na variável da temperatura retal. Com base no estudo realizado, observou-se que a inclusão de 8ml/dia de extrato etanoico de própolis a 30% na dieta de ovinos possibilitou uma menor variação nos parâmetros fisiológicos indicativos de estresse térmico, proporcionando um efeito positivo na homeotermia desses animais.

Avaliou-se desempenho zootécnico dos peixes cultivados, em função do peso médio, da taxa de sobrevivência, fator de conversão alimentar aparente, ganho de peso e biomassa. Para análise econômica utilizou-se a estrutura de custo operacional e indicadores de viabilidade econômica para avaliar a produção. O cultivo sem oferta de ração (M1), gerou prejuízos econômicos em razão dos baixos índices zootécnicos, dos altos custos de produção e lucro negativo, comprovando a importância da ração para o desenvolvimento adequado de O. niloticus. A oferta de ração atrelada a fertilização (M2), foi mais viável economicamente, pois seus índices de Rentabilidade e Lucratividade foram significativamente superiores aos demais tratamentos. Investir em manejos que possam reduzir a oferta do alimento natural (M3) pode influenciar negativamente na sobrevivência dos peixes, influenciando negativamente no lucro operacional e nos índices de rentabilidade e lucratividade durante o ciclo de produção. Concluímos que cultivos semi-intensivos de O. niloticus que utilizam ração em conjunto com o incremento do alimento natural na coluna d´água dos tanques, por meio da fertilização dos sistemas de cultivo, pode trazer benefícios econômicos ao produtor e minimizar os custos com a alimentação artificial.

Um dos principais entraves da caprinocultura no Brasil são as perdas econômicas causadas por parasitas gastrointestinais. Que além de diminuir a produção, ainda causa um aumento dos custos com aplicações de anti-helmínticos para o controle das parasitoses. Para diminuir esse custo foi desenvolvido o método FAMACHA©, que consiste na avaliação individual de cada animal para determinar o grau de anemia baseado no nível de infecção por parasitas hematófagos e tomar a decisão se o animal deve ou não ser tratado, diminuindo a pressão seletiva sobre os parasitas. No entanto, em raças localmente adaptadas, podemos encontrar mudanças fisiológicas adaptativas nas quais os animais apresentam parâmetros clínicos diferentes de animais de raças exóticas. Com isso, o objetivo deste trabalho foi avaliar eficácia da aplicação do método FAMACHA© em caprinos da raça Canindé, criados em sistema extensivo no semiárido brasileiro. Para tanto, foram utilizadas 161 cabras da raça Canindé, as quais foram examinadas clinicamente, e classificadas através do escore F© em 5 categorias, F©1, F©2, F©3, F©4 e F©5. Os animais foram diagnosticados como anêmicos (F©3,4 e 5 ou F© 4 e5) ou não anêmicos (F© 1, 2 e 3 e F© 1 e 2). Foi coletada amostra sanguínea para realização de hemograma e contagem do hematócrito, padrão ouro, para detecção de anemia, de cada animal, e realizada a coleta de fezes para contagem de ovos por grama de fezes (OPG) e realização de coprocultura para confirmação da presença de H. contortus através da identificação da sua larva infectante, em dois períodos do ano, seco e chuvoso. Diante dos dados obtidos, não houve diferenças significativas entre o os dados de HTC e F© entre os períodos analisados. No entanto, ao avaliar o F©, foi observado que a média da classificação dos animais permaneceu semelhante nos dois períodos, e a anemia não foi confirmada em nenhum animal pelo HTC, houve apenas diferença significante na contagem de OPG entre o período chuvoso e seco, no qual, os animais apresentaram uma menor média de OPG. Portanto, estudo concluiu que há uma relação contraditória entre a classificação da anemia através do método F©, valores de OPG e HTC relacionadas infecção por H. contortus, não sugerindo o uso do método F© para caprinos da raça Canindé e ainda propõe a elaboração de novas faixas de HTC associadas aos escores de F© de 1 a 5.

Os consumidores de energia residenciais brasileiros, enquadrados no grupo B pelo padrão da
ANEEL, atuam como agentes passivos quando o tema abordado tem relação com o controle
de consumo de energia em seus próprios domicílios, visto que os medidores de energia
instalados em seus padrões de entrada são de propriedade das concessionárias de energia e
apenas estas empresas tem acesso completo aos padrões de consumo dos seus clientes. Apesar
de se tratar de uma informação relevante, principalmente quando se trata de realizar alterações
e adoção de alternativas aos elevados valores de consumo de energia elétrica, os
consumidores deste grupo possuem pouca ou nenhuma informação que possa os auxiliar no
processo de conhecimento dos seus hábitos e padrões de consumo. Além disso, por se tratar
de um processo que utiliza equipamentos específicos e que, por vezes, necessitam de
profissional habilitado para seu correto manuseio, a obtenção de conhecimento específico
acerca deste tema torna este processo caro e muitas vezes inacessível à população geral. Desta
forma, com a visão de prover aos consumidores residenciais um meio para monitorar o
consumo de seus equipamentos elétricos de forma simplificada, de fácil instalação e fácil
acesso às informações, para este trabalho foi realizado o projeto simulado de um dispositivo
inteligente de medição de grandezas elétricas para utilização por consumidores residenciais.
Este dispositivo tomou como base outros dispositivos similares desenvolvidos em pesquisas
acadêmicas e também analisadores de energia comerciais profissionais para verificação do seu
funcionamento que, para as cargas testadas e comparadas, apresentou resultado satisfatório
em comparação com os demais equipamentos mencionados. O dispositivo desenvolvido de
forma simulada também servirá de base para trabalhos futuros, com o desenvolvimento físico
do mesmo para testes em ambientes residenciais reais

Published: February 2025

A agricultura de precisão objetiva a melhoria da eficiência nas atividades agrícolas através do
uso de técnicas de monitoramento das condições do plantio. Nesse contexto, um dos parâmetros
monitorados é o teor de umidade do solo, cuja medida indica o volume de água presente em
determinado volume de solo e cujo conhecimento permite direcionar as atividades de irrigação
para as áreas de campo que mais necessitam. Como alternativa aos sensores de umidade do solo
comerciais, surgem os dispositivos baseados em ressoadores de anel partido complementar, os
quais são estruturas metálicas planares artificiais que podem ser classificadas como um tipo de
metamaterial. Tais ressoadores são sensíveis as alterações dielétricas do meio em que inserem e
podem ser utilizados no projeto de sensores de micro-ondas, haja vista que é possível relacionar
a variação da sua resposta em frequência com o parâmetro de natureza física ou química a ser
quantificado. O objetivo desse trabalho é projetar e conceber um dispositivo planar baseado na
topologia metamaterial mencionada, que possa ser utilizado como sensor de micro-ondas para
estimar o teor de umidade do solo. Com o intuito de minimizar os impactos ambientais que
possam ocorrer devido ao esquecimento ou danificação do dispositivo durante sua utilização, o
material utilizado como substrato dielétrico é o poliácido lático, um termoplástico biodegradável
comumente utilizado na construção de objetos impressos em 3D. Os resultados de simulação
e de uso experimental do sensor quando submetido a situações hipotéticas e reais de variação
do teor de umidade em solos de diferentes texturas são apresentados. Por fim, um sistema de
monitoramento autônomo foi desenvolvido e integrado ao dispositivo. Os resultados obtidos
indicam a viabilidade do sensor proposto, haja vista que foi possível correlacionar a variação do
teor de umidade do solo com base no deslocamento da frequência de ressonância do mesmo

O crescente desenvolvimento das tecnologias em sistemas de comunicação sem fio, bem como
a variedade de dispositivos com operação em várias faixas de frequência, trazem o conceito
de antenas reconfiguráveis para funcionamento com múltiplos dispositivos receptores. As
antenas reconfiguráveis possuem a capacidade de irradiar mais de um padrão em diferentes
frequências que sejam necessárias nos sistemas de radar e de comunicação modernos. Algumas
antenas reconfiguráveis funcionam com alteração da frequência de funcionamento mantendo
suas características de radiação, outras funcionam a partir da reconfiguração do padrão de
radiação e também da polarização. Esse trabalho tem como objetivo o desenvolvimento de uma
antena de microfita reconfigurável utilizando o Ressonador de Anel Fendido Complementar
(Complementary Split Ring Resonator - CSRR), com intuito de analisar possíveis alterações
nos parâmetro de frequência de operação. Para tanto, foi realizada uma análise paramétrica do
metamaterial inserido no plano de terra de uma antena de microfita retangular para verificar
um comportamento de reconfiguração. Os parâmetros simulados, foram também comparados
com resultados de medições da antena e feita uma análise sobre a reconfiguração da antena.
Os resultados mostram uma boa correspondência entre simulação e medição. Para a antena
retangular padrão, a simulação mostra uma frequência de ressonância de 6,43 GHz e perda de
retorno de -13,02 dB, com largura de banda de 6,14 GHz a 6,78 GHz e os resultados da medição
mostram uma frequência de ressonância de 6,64 GHz, perda de retorno de -11,96 dB com largura
de banda de 6,41 GHz a 6,80 GHz

Authors: Losetty Venkatramana
Published: February 2025

This chapter discusses the application of polymers in cosmetics and personal care products and also explores how they are hazardous to harm human health and the environment. Cosmetics are used globally for beauty and contain many chemical substances, especially different types of polymers added during formulation. The quality, functionality, and shelf life are increased by the presence of these polymer substances which act as additives, fragrances, preservatives, stabilizers, surfactants, dyes, and shine enhancers. However, many toxic and hazardous polymer-based substances are present in cosmetics beyond acceptable levels. Cosmetic formulations become more attractive and marketable to consumers when bonded with polymers. The polymers are mixed with cosmetic products as modifiers and stabilizers including makeup, skincare, and hair care products. Some polymers are responsible for serious skin damage and even organ damage and can lead to cancer. This chapter will discuss the usage of polymers in cosmetics, and determine their types, like natural, semi-synthetic, and synthetic polymers present in cosmetics, and how their unique properties enhance the need in cosmetic applications. Many of these polymers are bioactive and tend to bio-accumulate and environmental impact which gives significant risk to human health and ecosystems. Therefore, natural polymers are highly valued in cosmetic formulations for their biocompatibility, safety, and environmental friendliness.
