Background: The quality of chicken meat, essential for consumer satisfaction, is influenced by skin pigmentation. The lack of carotenoids in conventional diets motivates the search for cost-effective alternatives to enhance these aspects in poultry production. Objective: This study assessed the impact of partially replacing commercial balanced feed with different levels of carrot flour (Daucus carota subsp. sativus) on productive parameters and the pigmentation of broiler chickens. Methods: 64 Cobb 500 birds were randomly assigned to four experimental diets, each with eight replicates of two birds. The control group (T1) received a standard diet, while experimental groups received a diet with 10% (T2), 15% (T3), and 20% (T4) replacement with carrot flour. Variables such as feed consumption, weight gain, feed conversion, mortality, skin pigmentation, and profitability were evaluated. Results: Treatments with 15% and 20% carrot flour showed higher feed consumption. Birds in experimental groups exhibited higher weight gain and improved feed conversion, with no reported mortality. Regarding pigmentation, carrot flour influenced skin color as its concentration in the diet increased. In terms of profitability, the 15% replacement treatment stood out by generating higher income and a superior cost-benefit ratio. Conclusion: Orange cultivar carrot flour can be a viable dietary source of natural pigment for broiler chickens. It may also be beneficial in promoting weight gain and reducing mortality, translating into economic advantages.
ENERGY EFFICIENCY AND DIGITALIZATION: CHALLENGES AND OPPORTUNITIES FOR UKRAINE'S CONSTRUCTION INDUSTRY IN THE CONTEXT OF ENERGY SHORTAGES
Authors:   VUSI, Plovdiv, Bulgaria, Pimenow S.
Published: December 2024

Against the backdrop of global challenges such as geopolitical instability, environmental threats, and social crises, Ukraine's energy system has come under unprecedented pressure, requiring tactical responses to the destruction of energy infrastructure as well as long-term strategic solutions to ensure its resilience and energy efficiency. Currently, state efforts focused on operational measures, including the restoration of damaged power plants, support for decentralized energy sources, and mobilizing foreign aid to meet seasonal demands. However, despite existing national programs, such as the National Energy Efficiency Plan, several unresolved aspects require further detailing and adaptation to current conditions. Specifically, there is a lack of concrete steps for integrating decentralized sources into building projects, flexible mechanisms to operate during infrastructure disruptions, and incentives for the widespread use of green technologies in large-scale construction.

This research aims to analyze the opportunities and challenges related to enhancing the energy efficiency of Ukraine's construction sector through innovative solutions such as artificial intelligence (AI), machine learning (ML), digital twins, and eco-friendly materials. The study utilizes methods of content analysis, comparative and situational analysis, as well as expert evaluation to develop practical recommendations for both construction companies and government bodies. The results indicate that technologies enhancing building autonomy and resilience, particularly digital twins and IoT, are the most effective during wartime. Larger-scale solutions, such as smart energy-efficient buildings, require foreign investment and they may be implemented in the post-war period. The introduction of AI and ML not only improves energy efficiency but also helps reduce the carbon footprint, which positively affects at the environment and aids in adapting to climate change.

Authors: Baksiyan Galust A. , Zavialov Alexander A. , Lishchuk Sergey V.
Published: December 2024

BACKGROUND: Primary pulmonary meningioma is a rare and clinically non-diagnosable tumor. Foreign literature describes not more than 70 cases of this disease. The tumor represents a single solid node, not having any specific features, which does not allow for setting the clinical diagnosis before the pathologic examination. The disease has various occurrence rates both among women and men. The diagnosis is to be set based on the morphological examination of the surgical material with small dimensions of the tumor (or biopsy samples for cases of large tumor). CLINICAL CASE DESCRIPTION: The patient А. (54 years of age) with a history of combined treatment 9 years ago due to being diagnosed with рТ2аN1М0, stage IIIB cervical cancer. According to the results from the computed tomography of the chest cavity organs, in segments S8/9 of the lower lobe of the right lung, the findings included a subpleural solid mass lesion with the size of 14×11 mm. According to data from further examinations (computed tomography of the chest cavity organs, of the abdominal cavity and of the minor pelvis; magnetic resonance tomography of the brain; esophagogastroduodenoscopy; colonoscopy), no other abnormalities were detected. Surgical treatment was arranged at the extent of thoracoscopic atypical resection of the lower lobe of the right lung. Anatomic pathology examination report on the resected tumor indicates the presence of “Pulmonary meningioma”. CONCLUSION: This clinical case represents the first documented experience of surgical resection of primary pulmonary meningioma in Russia.

Authors: Skvortsov Dmitry V. , Lobunko Danila A. , Ivanova Galina Е.
Published: December 2024

BACKGROUND: The stroke represents a significant medical-social problem due to its high morbidity and mortality with a tendency towards increasing the overall occurrence rates. A total 80% of the patients show persisting impaired functions of the upper limb. The current approaches, such as Clinical scales and Questionnaires, are being criticized for subjectivity and insufficient precision. It is necessary to develop an instrumental method for evaluating the functions of the upper limb, the method that is applicable in the clinical settings. AIM: To develop a functional test for the objective diagnostics of the wrist joint functions, applicable in the clinical settings. METHODS: A functional test was proposed for evaluating the biomechanics of the radiocarpal joint by means of using the inertial sensors. The research sample was a group of 15 healthy volunteers (5 males and 10 females aged from 23 to 33 years), not having any joint diseases or neurological disorders. The research was carried out within a period of one year (2022–2023). The primary endpoint was the determination of the amplitude, the time and the motion trajectory in the wrist joint when performing two tests - the “Wrist-0” and “Wrist-flex”. An assessment was done of the duration of the motion cycle, of the motion maximal amplitude and phase. RESULTS: The evaluation of the upper limb functions using the clinical scales (ARAT, FMA-UE, MRC) has demonstrated, that the parameters correspond to the ones in healthy individuals. When using the “Wrist-0” test, the motion amplitude was significantly lower than in the «Wrist-flex» test (p 0.05). No statistically significant differences were found in the motion amplitude between the right and left limbs determined using both tests (p 0.05). The maximal flexion phase for the “Wrist-0” tests occurs significantly earlier than for the “Wrist-flex” test for the right hand (p 0.05). The duration of the motion cycle did not significantly differ between the tests for the right hand (p 0.05) and was significantly higher for the “Wrist-flex” test in the left hand (p 0.05). CONCLUSION: A set of reference values was established for the functional tests. Insignificant differences were reported for the functions of the right and left radiocarpal joints. The test proposed requires insignificant time for its implementation and it can be used for objective diagnostics of the radiocarpal joint functions in patients.
Research on multi-path quadratic convolutional neural network-based bearing fault diagnosis
Authors: Ji Yingying , Gao Jun , Shao Xing , Wang Cuixiang
Published: December 2024

In real-world complex situations, high levels of noise from the surroundings and other component resonances frequently distort collected vibration signals, giving the collected data non-linear features. This research presents a multi-path quadratic convolutional neural network (MPQCNN)
for bearing fault diagnosis in response to the issue of the low generalisation performance of traditional deep learning-based bearing fault diagnosis methods and their limited diagnostic capabilities in noisy situations. The proposed MPQCNN combines an attention mechanism and a residual structure,
utilising the potent feature representation capability of quadratic neurons to process the input in noisy situations. By using dilated convolutions with different dilation rates, the receptive field of the MPQCNN is expanded and the multi-scale features obtained are fused to enhance the fault
diagnosis capability. Moreover, a dynamic balance adaptive threshold residual block is used to enhance the robustness of the model. To perform pertinent experiments, the MPQCNN uses bearing datasets from the Southeast University and Case Western Reserve University (CWRU). The results show
that the suggested approach has strong noise immunity. The diagnostic accuracy of the MPQCNN for the CWRU and Southeast University bearing datasets can reach up to 100% when the signal-to-noise ratio (SNR) is 6.

How might the title of Quinnopolis vs. Hamlet preliminarily inform our reading of this play? The "versus" seems to promise pugilistic as well as legal antagonism; more speculatively, this review posits an antagonism between staged productions and filmic conventions, with special attention to the song (and John Ford film) My Darling Clementine (1946).
The "Shakesteen" genre: Claire Danes's Star-Body, Teen Female Fans, and the Pluralization of Authorship
Authors: Keam Angela
Published: December 2024

Deploying a broadly cultural studies (and multidisciplinary) approach, this paper focuses on the emergence of what I term the "Shakesteen" genre. It considers this genre as performing a powerful and under-researched role in shaping adolescent gender and sexual identities. I focus specifically on the star-body of Claire Danes and the role that first catapulted her to stardom — that of Juliet in Baz Luhrmann's William Shakespeare's Romeo + Juliet. I argue that Danes's body offers her teen female following an alternative, private, unregulated site through which to access Shakespeare, his text and the character of Juliet. Through star/fan relations, which ultimately exceed the constraints of the filmic narrative, the teen female fan is able to experiment with different models of femininity and appropriate some of Shakespeare's cultural power for her own political means.

Through-thickness damage distribution in sheet bending employing the workability diagram
Authors: Lyamina E. A.
Published: December 2024

A semi-analytical solution is constructed to determine the through-thickness distribution of the average stress triaxiality parameter included in the ductile fracture criterion in sheet bending under the action of a bending moment and tensile force. It is assumed that the condition of the sheet is plain-strain. The sheet material is elastic-plastic, and the uniaxial yield stress is an arbitrary function of the equivalent plastic strain. The solution allows for predicting the occurrence of plastic fracture and the distribution of the degree of use of the plasticity reserve over the sheet thickness.
Computational and experimental studies of a pressure pulsation damper for pipeline systems
Authors: Mironova T. В. , Rekadze P. D. , Prokofiev A. B. , Rodionov L. V.
Published: December 2024

A generalized-structure analytical model of a pressure pulsation damper for pipeline systems is presented. The model was obtained using the four-pole method. The model is obtained in lumped and distributed parameters. The distributed-element model and finite element model are used for calculating the inherent characteristics of the pressure pulsation damper. The analytical distributed-element model takes into account the distribution parameters of the central inertial channel by introducing into the analytical model a matrix for the distributed element instead of the matrix of inertial resistance. A finite element parametric model of a two-stage reactive-type oscillation damper is developed in the Ansys software. Pulsation processes in the damper are modeled using acoustic analysis. The frequency-dependent coefficients of the damper transfer matrix are calculated for three models using three numerical experiments with a section of the pipeline system with the dynamic characteristics known in advance. The characteristic parameters of the pressure pulsation damper are calculated. These are the wave input impedance, wave output impedance and the inherent vibration damping. The calculation was carried out using analytical and finite element models. A single-stage reactive pressure pulsation damper is developed. The damper is designed in such a way that its settings such as the resistance of the jets and resonance tubes, the length of the central channel and the capacity of the expansion cavity can be changed. The results of experimental and numerical research of the inherent characteristics of a single-stage reactive of a vibration damper are presented.

Published: December 2024

The paper presents the results of simulation of spray and combustion processes in the liquid-propellant rocket engine chamber using the z77 reduced kinetic mechanism of chemical reactions and a hybrid method for determining spray parameters of a swirl atomizer. Simulation was carried out for the nominal operational conditions in a three-dimensional domain using the ANSYS Fluent software. The process of spraing liquid fuel components (T-1 kerosene and oxygen) by monopropellant injectors was simulated using a model of discontinuous phases. The simulation results (pressure, temperature and velocity) were compared with the data of analytical thermogasdynamic calculation results and experimental results for pressure in chamber and gas temperature near the wall. The difference between the simulation results and the experimental results does not exceed 8%. Thus, it was shown that it is possible to use the mechanism z77 and hybrid method for determining spray parameters of a swirl atomizer presented in this paper to obtain accurate simulation results of the kerosene T-1 and oxygen spray and combustion processes of the investigated liquid-propellant rocket engine.

Published: December 2024

A description of the developed models, algorithms and software for operational assessment of the energy balance on board spacecraft for optoelectronic observation of the Earth’s surface in order to monitor the achievement of the performance targets of a space observation system is given. On the basis of the obtained models and algorithms, a software module was developed for assessing the onboard energy balance in real time, used as part of the software for assessing the target and main design indicators of the space surveillance system. The module’s user interface provides windows for entering and controlling the initial data according to the parameters of the power supply system and cyclograms of connecting on-board system devices, as well as windows for displaying the results of energy balance modeling in digital form and in the form of dynamic diagrams. The use of software based on the proposed models and algorithms makes it possible to more reasonably and quickly develop the initial requirements for the designed onboard systems of remote sensing spacecraft of high-detail and operational observation and to accelerate the process of coordinating design characteristics of the spacecraft at the initial stages of design. The proposed methods, models and software are universal and can be used in the design of Earth remote sensing spacecraft with a wide range of target indicators, target equipment composition and onboard support systems.
Journeying Towards Decolonial Child and Youth Care
Authors: Boody Lois
Published: December 2024

Indigenous Child and Youth Care: Weaving Two Heart Stories Together by Cherylanne James is discussed in this review as a critical contribution to child and youth care education in Canada. James’s Indigenous feminist orientation invites child and youth care students to unlearn colonial narratives, to instead center Indigenous approaches to care. The reviewer highlights the effectiveness of James’s approach in engaging in “difficult knowledge” with learners to foster relational accountability, and shares how this approach models “journeying,” moving from deficit-centered orientations toward Indigenous-led, desire-based approaches for decolonial care. The text guides child and youth care students to reflect critically on their role in supporting Indigenous futurities.

The purpose of the work is to analyze the transport of passive particles in the velocity field of a two-vortex configuration on a plane with a possible presence of a shear flow. We model the system using two point vortices and a shear flow, where the velocity components depend linearly on one coordinate. Scenarios of particle transport and mixing are studied depending on the intensity of one vortex (in the region of [-1, 1]∖{0}) and various shear flows with fixed initial positions of the vortices and an intensity of the second equal to unity.

In the investigation, we mainly use numerical methods of dynamical systems analysis. We apply 8th-order of accuracy integrators to solve the Cauchy problem for a system of ordinary differential equations. The study also involved constructing Poincare sections and fields of local Lyapunov exponents, as well as studying transformations of marker circles (fluid contours) on a plane.

Results. Depending on the signs of the vortex intensities and the direction of the shear flow, the following scenarios were found: mixing of particles near the vortex structure; movement of a vortex pair along closed orbits with the transfer of particles from its vicinity and mixing near the orbits; mixing of particles in a large area on the plane; movement of a vortex pair to infinity with the transfer of particles from the vicinity of its initial position over long distances; disintegration of the pair and movement of vortices in different directions to infinity with the transfer of particles from the vicinity of their initial positions. In the presence of a shear flow, stochastic scattering of passive particles is typical, which is because of their chaotic dynamics.

Conclusion. We show that depending on the signs of intensities and parameters of the shear flow, a vortex pair can be a ’carrier’ moving particles from the vicinity of its initial position over long distances, a ’mixer’ of particles in a limited area of the plane, a ’scatterer’ of particles from a certain area along its path to infinity. The results of the article can be useful in explaining the complexity of transfer processes in fluids and gas flows when vortex pairs arise in them.

Background and Objectives: Understanding the epidemiology of Candida species among cancer patients is crucial for preventing invasive infections. This study aimed to identify Candida species and assess risk factors among cancer patients receiving chemotherapy in Birjand, eastern Iran.
Materials and Methods: The samples were obtained from the oral cavity of 140 patients and the initial identification of Candida species was carried out through fungal cultures. Subsequently, Candida isolates were molecularly identified using the PCR-RFLP method with the restriction enzyme Msp1. Furthermore, the demographic characteristics, risk factors, and clinical history of the patients were extracted and scrutinized using a multiple logistic regression model.
Results: Among the 140 patients examined, 55 individuals (39.3%) tested positive for oral candidiasis (OC). Notably, Hem- orrhagic cancer emerged as the most common type of cancer associated with OC (46.7%). The predominant species isolated was the Candida albicans complex (64.8%), followed by the Candida glabrata complex (26.8%). A noteworthy finding was the significant association between the occurrence of OC and the number of chemotherapy sessions (P<0.05). Conversely, no significant correlations were detected between OC and variables such as sex, age, type of cancer, occupation, residence, underlying disease, and drug use (P>0.05).
Conclusion: The prevalence of Candida spp. and its correlation with the number of chemotherapy sessions underscored the importance of preventive measures. These findings provided valuable insights for designing targeted interventions to miti- gate the burden of oral candidiasis in this vulnerable population.

Published: December 2024

Background and Objectives: Plant growth-promoting rhizobacteria (PGPR) with a diverse set of traits can improve crop yield in agriculture. The current study aimed to evaluate the potential of multi-trait PGPR isolates as inoculants for maize (Zea mays L.) growth.
Materials and Methods: In this study, 23 bacterial isolates were initially screened from maize plant rhizosphere. Ten iso- lates (A1–A10) were selected based on N fixation, P and K solubilization and their in vitro specific PGPR traits, such as solubilization of Zn, and Mn, the production of IAA, siderophore, ammonia, and HCN were assayed. Finally, the potential of selected isolates in enhancing the germination, height, shoot collar diameter, shoot fresh and dry weight biomass, and root dry weight of maize were evaluated.
Results: Among the positive-PGPR colonies, the selected isolates demonstrated the better performance of PGPR traits such as highest nitrogen fixation, P, K, Mn, and Zn solubilization, and production of siderophore, HCN, NH3, and IAA. In addi- tion, the maize seed germination and improvement of maize yield in a pot experiment were observed after their treatment by bacterial inoculants. Biochemical characteristics, 16S rDNA amplification, and sequencing demonstrated a high similarity of PGPR isolates to the strains of Enterobacter, Pantoea, Kluyvera, Lelliottia, Klebsiella, Pectobacterium, and Stenotro- phomonas.
Conclusion: The findings demonstrated that these strains could prove effective PGPR inoculants for the improvement of maize crops as multiple bio-fertilizers.

The most stable conformation of molnupiravir (C13H19N3O7), which is frequently used in the COVID-19 treatment, was elucidated by the Spartan06 program. Using the CAVER program, the potential active binding sites that belong to the spike glycoprotein, ACE2 receptor, and both the apo and holo forms of the main protease enzyme(Mpro) of COVID-19 were identified. To determine the binding affinity of molnupiravir to target receptors, molecular docking analyses were carried out using Autodock Vina. The results of molecular docking calculations of the molnupiravir with the spike glycoprotein (PDB ID:6VXX), ACE2 (PDB ID:6M0J;1R42), the apo form (PDB ID: 6M03) and the holo form of COVID-19 Mpro (PDB ID: 6LU7) showed strong binding affinities at -7.8, -7.7, -7.7, -7.1, and -7.4 kcal/mol, respectively. Moreover, top-scoring ligand-receptor complex of the molnupiravir with ACE2 (1R42) were subjected to 50 ns all-atom MD simulations to investigate the ligand-receptor interactions in more detail.

A problemática relacionada ao conforto térmico abrange uma variedade de desafios e complexidades que surgem da interação entre as condições climáticas, fatores ambientais e arquitetônicos. O objetivo deste trabalho é avaliar o conforto térmico (CT) em um município da Amazônia durante meses do período seco de 2023 e verificar se há uma relação entre o CT e os níveis de material particulado (PM), a fim de fornecer insights relevantes para a compreensão das condições no ambiente. Foram utilizados dados diários de temperatura do ar (°C), umidade relativa do ar (%) e material particulado PM2,5 e PM10 disponibilizados pelo kit de monitoramento da qualidade do ar do projeto Rede Piloto de Inovação no Monitoramento da Qualidade do Ar na Região do Oeste do Pará: Cuidadores do Ar, de julho a outubro de 2023 meses pertencentes ao período seco na região. Utilizaram na metodologia o Índice de Temperatura e Umidade (ITU) e a técnica de correlação linear de pearson. Como resultados principais destaca-se que o ITU para todo o período analisado se mostrou na categoria extremamente desconfortável (ITU> 26) e a correlação entre o ITU e os PMs apresentou classificação positiva de moderada à fraca (0,43 e 0,36). Conclui-se que a elevação de temperatura e umidade no período seco da região gera significativo desconforto térmico (ITU > 26), com uma correlação positiva, embora moderada a fraca, entre desconforto térmico e material particulado (PM). Esses resultados indicam a necessidade de ações coordenadas entre governo, comunidades e instituições acadêmicas para desenvolver intervenções práticas e sustentáveis, indo além do monitoramento e promovendo medidas de mitigação eficazes.

Published: December 2024

Es un hecho que el clima de Cuba ya experimenta algunos impactos específicos del cambio climático global. Entre ellos, la incidencia creciente de efectos meteoro-trópicos extremos, que además de los ya conocidos peligros hidrometeorológicos (huracanes, intensas lluvias, penetraciones del mar, fuertes vientos y sequías), incluyen ahora las sensaciones intensas de calor y frío, los eventos notables de contaminación atmosférica y los cambios bruscos del estado del tiempo. Estos peligros tienen orígenes distintos y ocurren de manera diferenciada en el transcurso de las épocas del año, casi todos son factores predisponentes de diversas meteoropatías, y en los casos más notables, contribuyen al aumento de la mortalidad diaria en exceso. El presente artículo trata de establecer relaciones específicas entre los procesos sinópticos influyentes y las condiciones locales del régimen térmico, con la mortalidad en exceso de las mitades occidental y oriental de Cuba, partiendo de una base de datos de estas variables para el período 2001-2020. Se encuentran relaciones bien definidas entre los días con mortalidad en exceso y la presencia de efectos meteoro-trópicos extremos, identificados entre los tipos y subtipos de situaciones sinópticas influyentes sobre Cuba, los cambios contrastantes del contenido de oxígeno del aire y el comportamiento extremo de la temperatura del aire. Estas relaciones tienen diferencias estacionales en la génesis, características y duración de los máximos de mortalidad, las cuales se explican por diferentes factores que actúan simultáneamente. Se identifican las condiciones de inicio de las posibles meteoropatías asociadas a los extremos del régimen térmico, llegando a una estimación preliminar de la ocurrencia de las olas de calor y frío en las mitades occidental y oriental de Cuba. Dada la amplitud del tema tratado, se recomienda su continuación, en el contexto del desarrollo de los servicios de pronóstico biometerológico como herramienta operativa esencial para enfrentar los impactos de la variabilidad del clima y del estado del tiempo.

Este estudo analisa a relação entre as frequências de Ressonância Schumann (RS) e as taxas de mortalidade por infarto agudo do miocárdio (IAM) no Sul (S) e Nordeste (NE) do Brasil, utilizando dados geomagnéticos coletados entre 1996 a 2022 das estações de São Luís (SLZ) e São Martinho da Serra (SMS). A Transformada Discreta de Fourier (DFT) foi aplicada para identificar as frequências de RS, enquanto uma análise de cluster agrupou os estados em três padrões distintos. A região Sul mostrou maior correlação com as frequências de RS, devido à proximidade com a Anomalia Magnética do Atlântico Sul (AMAS), onde o campo magnético é mais fraco, amplificando os impactos geomagnéticos na saúde cardiovascular. Já no Nordeste, as associações foram menos consistentes, possivelmente influenciadas por fatores locais. Os resultados ressaltam a importância de considerar variações geomagnéticas na análise de riscos à saúde, sugerindo implicações relevantes para a saúde pública em regiões expostas.

O objetivo do trabalho foi quantificar o ganho de calor via radiação de ondas curtas por ovelhas mestiças com diferentes padrões de pelame em sistema de criação a pasto sem oferta de recurso de sombreamento. Foram avaliadas nove ovelhas mestiças com pelame de coloração branca, marrom e preta sem acesso a sombra. A pesquisa foi conduzida na Fazenda Experimental de Iguatemi pertencente à Universidade Estadual de Maringá. Os parâmetros fisiológicos coletados foram a frequência respiratória e a temperatura superficial dos animais. Os parâmetros meteorológicos foram: temperatura (ºC) e umidade relativa dor ar (%) e radiação solar (Wm-2). O ganho de calor por radiação de ondas curtas foi quantificado a partir dos componentes de radiação direta, difusa e refletida e considerando a absortância do pelame das ovelhas.  Os dados foram analisados pelo método dos quadrados mínimos e o desdobramento das médias pelo teste de Tukey a 5%. A temperatura do ar variou entre 30,2°C e 41°C, e a umidade relativa com média de 63%; enquanto a radiação solar ultrapassou 1100Wm-2. O ganho de calor diferiu significativamente entre os pelames (P<0,05), com os animais pretos, marrons e brancos absorvendo em média 1037, 600 e 460Wm-2, respectivamente. Os animais pretos e marrons apresentaram frequência respiratória média de 119resp.min-1, diferindo (P<0,05) dos animais brancos com 109resp.min-1. Logo, animais de pelame marrom possuem melhor adaptação a ambientes tropicais, pois apresentam maior pigmentação de pele em relação aos animais brancos e absorvem menor quantidade de calor que os animais pretos.

Foram utilizadas 5 búfalas submetidas a ambiente com lagoa artificial com sombra e sem sombra. A pesquisa foi conduzida na Fazenda Experimental de Iguatemi. A frequência respiratória (FR) foi monitorada a cada 30 minutos como parâmetro fisiológico. A temperatura, umidade relativa e radiação solar, foram registradas a cada 10 minutos. Utilizando uma câmera infravermelha, foram capturadas imagens das regiões corporais: dorso, olhos, focinho e barbela. A análise de variância dos dados meteorológicos e FR foi realizada pelo método dos quadrados mínimos, com desdobramento das médias pelo teste de Tukey-Kramer. Foi realizada a correlação de Pearson entre a média das temperaturas superficiais e as variáveis meteorológicas para avaliar a janela térmica dos animais. A temperatura do ar variou entre 30,2°C e 41°C, com 63% de umidade, e a radiação solar entre 770 W.m⁻² e 1106 W.m⁻². A FR variou entre 19 e 29 resp min-¹. A correlação entre a temperatura do focinho e a TBS ao sol foi de r = 0.87 e com a UR foi de r = -0.83; para a temperatura do olho, TBS ao sol foi de r = 0.76 e UR r = -0.70; para a barbela, TBS ao sol r = 0.68 e UR r = -0.69; TBS à sombra da barbela r = 0.64. A termografia foi eficaz em capturar a resposta térmica dos animais ao ambiente, validando sua utilidade na avaliação do bem-estar.

Este trabalho avaliou a influência das condições atmosféricas na percepção térmica dos ocupantes, considerando-se diferentes tipos de vidro, observando-se a interferência do turno de exposição e do contato visual com o exterior. Para tanto, 48 voluntários expostos a 3 tipos de vidro (claro e 2 de controle solar) em uma câmara climática walk-in, em condições de céu claro, parcialmente encoberto e encoberto, nos períodos da manhã e da tarde, com e sem contato visual com o exterior. Foram medidas variáveis térmicas ambientais, fisiológicas e aplicados questionários de percepção térmica, posteriormente comparados ao PMV calculado. Os dados coletados foram analisados estatisticamente. Obteve-se que as avaliações térmicas dos ocupantes têm relação com o tipo de céu, mas independem do tipo de vidro, bem como da relação entre ambos. Observou-se também que a percepção térmica tem relação com o turno de participação, assim como com a interação entre este e o tipo de céu. Por fim, que o contato visual com o exterior afetou a forma como as condições atmosféricas influenciaram o voto de percepção térmica dos voluntários. Concluiu-se que as condições atmosféricas influenciaram a percepção térmica dos participantes, independentemente do tipo de vidro, e que a o turno e o contato visual com o exterior podem interferir na maneira como essas condições influenciam os votos térmicos, mas de maneiras distintas. Portanto, a climatização e o leiaute dos ambientes podem se utilizar destes aspectos para a sua otimização tanto na oferta de conforto aos usuários, quanto para o uso racional de energia.

O presente estudo analisa os resultados de mais de uma década de funcionamento do SACDENGUE - Sistema de Alerta Climático de Dengue, elaborado pelo Laboratório de Climatologia - LaboClima, da Universidade Federal do Paraná. Baseando-se no princípio de divulgação de informações científicas à população e aos sistemas de saúde, o estudo tem por objetivo reconhecer e valorizar a importância das atividades de monitoramento, mapeamento e alerta de riscos climáticos para a circulação de enfermidades, permitindo identificar a formação de situações meteorológicas favoráveis à reprodução de vetores e/ou à disseminação de agentes patológicos com potencial de causar prejuízos à sociedade, contribuindo assim para o planejamento e a gestão de riscos climáticos. Para tanto, as atividades possuem vínculo direto com o ensino-pesquisa-extensão, tendo em vista a metodologia estruturada em três pilares que contemplem a difusão dos produtos e conhecimentos gerados, sendo eles: 1) a elaboração e divulgação de mapas e boletins semanais de alerta climático; 2) o desenvolvimento e aprimoramento de Sistemas de Alerta Climático através de revisão de literatura teórico-conceitual; 3) atividades de treinamento de discentes da graduação e pós-graduação em nível técnico, analítico e de pesquisa na área de Climatologia e Geografia da Saúde. Através da análise da série histórica de funcionamento do sistema, foi possível identificar a predominância de uma área de alto risco climático para a dengue nas regiões norte, noroeste e oeste do Paraná. Desse modo, espera-se que, por meio da produção de novos conhecimentos e sua difusão, o projeto possa contribuir diretamente com os órgãos de saúde em diversos níveis e para o benefício da população paranaense e brasileira.
Społeczne wytwarzanie przestrzeni na przykładzie analizy szpitali psychiatrycznych w Łodzi
Authors: Sawiak Joanna
Published: December 2024

W artykule podjęto się szczegółowej analizy organizacji przestrzennej szpitali psychiatrycznych znajdujących się na terenie Łodzi. Jego podstawą jest badanie case study przeprowadzone z zastosowaniem metodologii jakościowej (analiza wizualna i obserwacja). Omawiane w artykule przypadki są prezentowane jako dwa charakterystyczne dla Polski rodzaje szpitali psychiatrycznych, których analiza służy zrozumieniu znaczenia sposobu ich organizacji dla społecznego postrzegania osób z chorobą psychiczną. W artykule znajdują się również odwołania do prac kluczowych dla zrozumienia problematyki chorób psychicznych, ich leczenia w instytucjach totalnych oraz roli społecznego wytwarzania przestrzeni. Zestawienie wyników analizy case study z wcześniej wspomnianymi koncepcjami pozwoliło na wskazanie możliwych sposobów oddziaływania organizacji przestrzennej szpitali psychiatrycznych na sposób ich postrzegania.
Substytucja jako element spójności w dyskursie pacjentów z afazją mieszaną

Substytucja, rozumiana jako zastępowanie docelowego elementu leksykalnego innym, to zjawisko lingwistyczne pojawiające się zarówno w dyskursie zaburzonym, jak i w mowie osób zdrowych. Wszelkie zamiany słów w wypowiedzeniach mają niewątpliwie wpływ na spójność komunikatów, a tym samym na ich interpretację przez interlokutora. W niniejszym artykule zbadano, jakie substytucje pojawiają się w wypowiedziach osób zdrowych oraz osób z afazją mieszaną z komponentami czuciowym i ruchowym. Zweryfikowano wpływ zamian leksykalnych na utrzymanie spójności na poziomie mikrostrukturalnym (kohezji), a także to, jak zakłócenia spójności mikrostrukturalnej wpływają na spójność makrostrukturalną (koherencję). Opis badań i analiz poprzedzono doniesieniami z literatury, które dowodzą zarówno zwiększenia występowania substytucji, jak i obniżenia zdolności do utrzymywania spójności dyskursu w mowie osób z diagnozą afazji mieszanej.
Łże-reportaże i prawdziwe fikcje

Celem autorki było zdefiniowanie i usystematyzowanie gatunków literacko-dziennikarskich powstających współcześnie, w czasie postprawdy, oraz warunkowanych zwrotem performatywnym. Autorka odtwarza historyczne tło narodzin powieści oraz dziennikarstwa, a następnie analizuje realizacje gatunków literacko-dziennikarskich ostatnich dwu dekad w literaturze polskiej. Zjawiska te interpretuje w odniesieniu do analogicznych gatunków w literaturze anglojęzycznej.
Książka stanowi ciekawe studium na temat współczesnego, szeroko rozumianego reportażu. Napisana kompetentnie i ciekawie, będzie, jak sądzę, ważną lekturą dla czytelników zajmujących się formami literacko-dziennikarskimi. Autorka wykorzystała oryginalny pomysł uporządkowania – na tle historycznym i europejskim – nowych gatunków dziennikarskich, wyłaniających się z kolejnych zwrotów w humanistyce. Innowacyjność pracy polega na umiejętnym przełamywaniu przez autorkę stylu naukowego stylem dziennikarskim, felietonowym, co jest niewątpliwie zaletą książki napisanej „z pazurem”, miejscami lekko i dowcipnie, szczególnie gdy autorka włącza w narrację anegdoty. Eklektyczność stylu – zindywidualizowanego i oryginalnego – właściwie koresponduje z rozważanymi przez nią gatunkami-hybrydami.

Background: Currently, new agri-food technologies have unveiled the nutritional value of barley. Our study focuses on the nutritional enhancement of barley (Hordeum vulgare L.). This study compares the nutritional characteristics of fermented and unfermented barley from Tiaret, Algeria. The analysis focuses on various physicochemical parameters, mineral compositionand heavy metals. Methods: The methods applied included the determination of dry matter (AOAC 9001.1), lipids (AACC 86-38), proteins (AOAC 950.09), gluten (AACC 38-10.01) and fibers (AACC 32-01.01). Acidity and pH were measured according to the current AACC standards (02.02.02, 02.52.01). Phenolic compounds were extracted using Kondakova’s methodand antioxidant activity was evaluated by DPPH. X-ray fluorescence spectrometry and atomic absorption spectrophotometry were used to determine mineral compounds and heavy metals. Result: Results revealed the significant differences between fermented and unfermented barley. Fermented barley showed higher water content (9.68% vs 6.34%), less protein (9.06% vs 10.76%), more lipids (1.91% vs 1.55%) and fewer total fibers (6.08% vs 8.06%). Fermented barley had higher acidity and lower pH. It is richer in polyphenols but lower in flavonoids. Mineral composition also varies, with generally higher levels in unfermented barley, except for calcium and chlorine. Both types of barley showed low concentrations of heavy metals.This study highlights the nutritional differences between fermented and unfermented barley, offering interesting perspectives for their use in the agri-food industry. The distinct profiles of these barley types suggest potential for targeted applications in food processing and product development, considering their specific nutritional attributes and functional properties, taking into account the consumer’s consumption habits.
