Authors: Afanasyev A. O.
Published: July 2024

The paper provides a comprehensive analysis of the issues of employees’ participation in administration of an organization within the framework of the Eurasian Economic Union. The author begins the research with the history of the emergence of the right of employees to participate in the management of the organization, moving on to the analysis of current trends in corporate governance, where he pays special attention to the role of employees in making key decisions. It is emphasized that the active involvement of employees in the management of the organization not only contributes to the democratization of labor relations, but also directly correlates with increased labor productivity, improved corporate culture and overall job satisfaction. Through a historical review, the development of the idea of employees’ participation in management is shown: starting from the period of the birth of labor law in medieval Europe to modern practices in the member states of the Eurasian Economic Union. A separate section is devoted to the theoretical foundations of employees’ participation in management. The main part of the study focuses on the analysis of general trends and national characteristics of employees’ participation in the management of organizations in each of the EAEU member States. In conclusion, recommendations are presented concerning optimizing the mechanisms of employees’ participation in management at the level of the Eurasian Economic Union. Attention is focused on the need to take into account both common approaches and national characteristics. The author describes key problems and challenges that need to be overcome for the effective implementation of employees’ participation practices in management.

Published: July 2024

BACKGROUND: Luminal HER2-negative breast cancer is the most common type of tumor in women diagnosed with early-stage breast cancer. Stromal cells and immune cells in tumor microenvironment have been reported to play a significant role in cancer prognosis. The prognostic role of tumor-associated neutrophils in early breast cancer remains mostly unclear.
AIM: To study predictive role tumor-associated neutrophils in early luminal HER2-negative breast cancer.
MATERIALS AND METHODS: The dataset consisted of 60 patients with early luminal HER2-negative breast cancer treated in S.P. Botkin City Clinical Hospital (Moscow, Russia). We first estimated basic morphological signs: tumor size, tumor grade (by Nottingham Histologic Score), tumor-infiltrating lymphocytes, lymphovascular invasion, hormonal receptors status, proliferative index, regional lymph nodes status. The expression of intratumoral neutrophils was studied using immunohistochemistry with CD15.
RESULTS: High tumor-associated neutrophils concentration was correlated with tumor size, high grade tumors, proliferative index, tumor-infiltrating lymphocytes, lymphovascular invasion and positive regional lymph nodes.
CONCLUSION: Tumor-associated neutrophils predicted a worse prognosis in early luminal HER2-negative breast cancer.

Authors: Reza Marco , Llamazares Sebastián , Iñiguez Alvaro , Romero Santiago , Fraga Arturo
Published: July 2024

In Latin America, the COVID-19 pandemic, which initially surged and is now a constant presence, has brought about significant health challenges due to disparities and differences in regional responses. Vaccination is not only a necessity but also a responsibility as the primary tool for prevention. However, its implementation has not been consistent across countries, leading to various challenges such as global demand, initial high costs, infrastructure limitations for distribution, public hesitance, and misinformation. Other issues, like vaccine efficacy in immunocompromised patients and the use of different vaccines, were initially questioned but are now regarded as strategies to protect patients. This region, with its unique traditions, also faces several risk factors including vaccine supply shortages, lack of vaccine manufacturing, overcrowded cities, and an increasing migrant population that adds to the vulnerability of the people, challenging countries to strive for equity in prevention strategies. It is important to address individual strategies in communities to increase vaccine uptake as part of public health policy, and collaboration between countries should be encouraged to reach more people. This review will provide information about the COVID-19 vaccines available in the region, their characteristics and composition, their use across countries, and the reported effectiveness in the general population and among those with weakened immune systems.

Authors: Hekal Mahmoud , Eskandar Kirolos
Published: July 2024

Background: Surgical care has evolved significantly over the years, with the introduction of Enhanced Recovery After Surgery (ERAS) programs emerging as a transformative approach. This literature review delves into the essential elements of ERAS, aiming to provide a comprehensive understanding of its impact on perioperative care and patient outcomes.
Main Body: The preoperative phase of ERAS involves meticulous patient preparation, encompassing strategies such as preoperative counseling, carbohydrate loading, and minimizing bowel preparation. These components collectively contribute to reducing preoperative anxiety, enhancing nutritional status, and mitigating the adverse effects of fasting, ultimately facilitating a smoother transition to surgery.
Intraoperative considerations within ERAS focus on techniques that minimize surgical stress, optimize fluid management, and implement pain control protocols. These critical interventions help to reduce surgical complications, accelerate postoperative recovery, and lessen the duration of hospital stays.
The postoperative phase is a cornerstone of ERAS, emphasizing early mobilization, optimized nutrition, and multimodal pain management. By incorporating these elements, ERAS programs aim to expedite recovery, decrease the risk of complications, and enhance patient satisfaction.
However, despite the evident benefits, implementing ERAS programs in clinical practice is not without challenges. This review discusses the barriers to ERAS adoption, including resistance to change, resource allocation, and the need for multidisciplinary collaboration.
Conclusion: Thence, ERAS represents a revolution in surgical care, offering a holistic approach to enhance patient outcomes, reduce complications, and shorten hospital stays. By exploring the key components of ERAS, this literature review provides valuable insights into the potential for widespread adoption and the imperative need to overcome implementation barriers. Ultimately, ERAS holds the promise of revolutionizing the future of surgical care, redefining standards, and improving the overall quality of patient experiences.

Published: July 2024

This article presents the results of the study of multifunctional properties of a new composition, with the conventional name AZ-1, which was prepared from various reagents under laboratory conditions. For this purpose, the results of its effect on a number of rheological parameters of commodity oil and the corrosion rate in hydrogen sulphide formation water have been interpreted. Laboratory experiments were conducted using concentrations of 100, 300, 500, 700 and 900 g/t of the composition, all following established standard methods. For the research purposes, the oil sample was taken from Narimanov field of SOCAR, and the aggressive medium was hydrogen sulphide formation water taken from well No. 1082 of “Bibiheybatneft” OGPD. Numerous experiments have shown that the optimum consumption rate of AZ-1 composition is 700 g/t. AZ-1 composition reduces the freezing temperature from +14°C to –8°C by improving the fluidity of the studied oil sample at optimal viscosity. The value of the shear stress limit of the anomalous oil sample is also drastically reduced. During the experiments carried out using the “cold finger test” method, it was found that AZ-1 composition has a high effect on oil deposits. At the temperature of +5°C of the “cold finger test”, its efficiency was 90% at the optimal consumption rate. During the effect of AZ-1 composition on the corrosion rate in hydrogen sulphide formation water, the protection effect increases at the concentration of 100–700 g/t and varies between 85–98%. At 900 g/t, the value of the protective effect is relatively reduced to 82%, and this is an indicator that the optimum consumption rate of AZ-1 composition is 700 g/t.

Published: July 2024

Background: Crop production relies heavily on essential nutrients. Balanced soil-applied fertilizers, along with foliar sprays, can improve input efficiency and crop performance, particularly in rainfed areas prone to moisture stress. Method: A field investigation was conducted at the experimental farm of School of Agricultural Sciences, Nagaland University, Medziphema campus, during rabi season of 2021. The experiment was laid out in split plot design with three replications with four main factors comprising of soil-application of different doses of N (nitrogen) in two splits (based on RDF of 40 kg N ha-1) viz., 100 % N, 75% N, 50% N and 25% N and five sub-factors comprising of foliar sprays of N viz. Control (water spray), single spray of Nanourea @ 3 ml liter-1, two sprays of Nanourea @ 3 ml liter-1, single spray of Urea @ 2% and two sprays of Urea @ 2 %. Result: Among the different soil application treatments, significantly highest NUE (Agronomic Efficiency), seed yield (996.80 kg ha-1) and stover yield (3032.10 kg-1) was recorded with soil application of 100 % N ultimately recording the highest net return (Rs. 26004 ha-1) and IBCR (5.80). Whereas, two sprays of Nanourea @ 3 ml L-1, among foliar treatments, recorded the highest NUE (Agronomic Efficiency), seed and stover yield (918.44 kg ha-1 and 3032.26 kg ha-1 respectively) as well as net returns (Rs. 22988 ha-1) and IBCR (5.5).

Authors: Wang Yuntao , Xie Jihong , Sun Zhen , Wang Qiqi , Yu Linqing
Published: July 2024

Background: Alfalfa (Medicago sativa L.) is a globally important cool-season forage grass for semiarid regions and the demand for seeds is increasing with the increase of alfalfa planting area. However, its seed yield is often low or inconsistent. Methods: A field experiment was conducted to investigate the response of seed yield and yield components of alfalfa to different sowing dates and phosphorus (P) fertilization levels from 2020 to 2022. This research was conducted using a split-plot design in a randomized complete block, with four replications. The main plots were three sowing dates (20 July, 5 and 20 August) and subplots were five different rates (0, 40, 70, 100 and 130 kg P2O5 ha-1). Result: Our results revealed that delaying the sowing dates reduced seed yield, by influencing its yield components, except for the 1000-seed weight, but P fertilization enhanced the seed yield components affected by late sowing and increased seed yield, it is recommended to apply P fertilizer at 77.6~144.8 kg ha-1. Stem density and seeds per pod were the primary factors determining seed yield and they may be useful to consider in developing traits for high-seed-yield alfalfa.
Vitrina del territorio

Published: July 2024

A través de la revisión de periódicos, cartas, textos e ilustraciones que no son parte de los registros oficiales, este articulo propone reconstruir un relato hasta ahora no contado: la primera participación chilena en una exposición universal, The Great Exhibition of the Works of Industry of all Nations de 1851. Durante esta, Chile exhibió trozos tangibles de su territorio tras una vitrina, y por primera vez, frente al mundo. La revisión de esta asistencia permite repensar el entendimiento de su territorio, identificado en sus inicios como pobre, a uno posteriormente productivo y altamente codiciado. Los hallazgos de estos documentos que, al parecer perdidos en los archivos del tiempo por 171 años, comparecieron orbitando la exposición, mas no son parte de esta. A su vez, permiten completar un vacío en el conocimiento y potencialmente abrir nuevos discursos en la historia cultural y política de esa época.
1499 | Unruhige Zeiten im Fricktal.
Authors:   Kantonsarchäologie Aargau, Brugg (CH), Winkler Andrea , Wälchli David , Hüsser Linus , Doppler Thomas
Published: July 2024

Zwischen 1987 und 2022 stießen die freiwilligen Bodenforscher der Fricktalisch-Badischen Vereinigung für Heimatkunde und die Kantonsarchäologie Aargau in neun Fricktaler Gemeinden auf spätmittelalterliche Brandschichten. Dabei kamen unerwartete Funde zum Vorschein. Sie zeigen einen Wohnstandard, den man im ländlichen Raum nicht erwartet hätte. Davon zeugt etwa die hohe Qualität der Ofenkeramik, die bis anhin vor allem aus dem städtischen Kontext bekannt ist. Die vorliegende Arbeit wertet diese spätmittelalterlichen Brandschichten aus und setzt sie in einen Zusammenhang mit dem im Jahr 1499 tobenden Schwabenkrieg. Historische Quellen belegen, dass eidgenössische Truppen während des Schwabenkriegs von 1499 auch im habsburgischen Fricktal Dörfer plünderten und anzündeten.
O Convento do Carmo do Rio de Janeiro
Authors: Dias Ana Beatriz Mendonça
Published: July 2024

Este artigo abrange a trajetória de mais de quatro séculos do Convento do Carmo no Rio de Janeiro, desde sua construção no período colonial até os desafios enfrentados nos dias atuais. O edifício emerge como um testemunho vivo das transformações políticas, sociais e culturais que marcaram a história da cidade. Ao longo do tempo enfrentou uma desvalorização sistemática, evidenciada pelo pensamento pejorativo acerca do colonial e que culminou numa reforma descaracterizadora da fachada em 1906. Posteriormente, na década de 1980, a inserção de uma torre agravou as ameaças à sua integridade e estrutura. Enquanto isso, os processos de tombamento, iniciados em 1964 e 2008, representam uma resposta consciente, ainda que tardia, à urgência de preservação. A retomada governamental em 2011 e as reformas de 2022 marcam esforços cruciais para revitalizar esse relevante patrimônio histórico e cultural, destacando a necessidade contínua de proteger e celebrar a rica herança da cidade do Rio de Janeiro.

Eccentric Positionality in Addictions - Moral Aspect of Addictions
Authors: Maršić Luka , Vojnović Daniela
Published: July 2024

Aim: The aim of this paper is to review the moral aspect of addictions. With the advancement of technology that brings more and more possibilities to a human being, understanding the principles of one’s own mind and the principles of the epoch in which the same mind lives, becomes necessary for a free life. Materials and Methods: The materials we included into our work include a noteworthy literature dealing with this challenges. Results: In addiction, in which a person has the impression of controlling the substance, enjoying the blissful role of the victor carried on a misbalanced concept of eccentric positionality, until he/she himself/herself becomes the very object he longed for, being a mere object in his own life, so the postmodernist concept of humanity sinks and withers in a bubble of the safety of the supra-cultural mind hooked on the illusion and the power of technique. The concepts of science bring a different view of things, and thus the metaphysical abstract concept of conscience as a divine voice that leads towards the principles that in some epoch arose from the knowledge reached at that time, that is, beliefs, disintegrates. Conclusion: The significance of these theses is that they could be applicable in expanding the view on addictions, which is necessary, taking into account the changes in the mental environment (epoch).
Combined Use of Phosphatidylethanol and the Audit Test for Detecting of Alcohol Abuse
Authors: Razvodovsky Yury Evgeny , Vladimirovitz Schuriberco Aleksey
Published: July 2024

Aim: To estimate the prevalence of alcohol abuse among men by using combined the direct biochemical marker phosphatidylethanol (PEth) and the AUDIT questionnaire (Alcohol Use Disorders Identification Test). Subjects and Methods: The concentration of PEth was determined in 136 blood samples of men aged 15 - 65 years. The blood was obtained from the laboratory of the medical advisory centre, where it was submitted for routine biochemical analysis. Immediately before blood sampling, clients were asked to complete the AUDIT questionnaire. Determination of the concentration of PEth was carried out using the method of high performance liquid chromatography - tandem mass spectrometry (HPLC - MS). Statistical data processing was carried out using the Statistica 10.0 program. Results: Discrimination by the level of alcohol consumption using the concentration of PEth showed that the proportion of abstinents (practically not drinking alcohol) among men was 20.6 %; the proportion of moderate drinkers was 63.1 %; the proportion of alcohol abusers was 16.3 %. The highest average concentration of PEth, as well as the proportion of those who abuse alcohol, was observed in the age groups of 50 - 59 and 60+ years. The distribution by level of alcohol consumption according to the total score of the AUDIT test was as follows: abstinents - 17.9 %; moderate drinkers - 69.6 %; alcohol abusers - 12.5 %. The highest average test score, as well as the highest share of alcohol abusers, was observed in the age group 50 - 59 years. Correlation analysis did not reveal any relationship between the concentration of PEth in the blood and the total score of the AUDIT test in any of the age groups of men. Conclusion: The results indicate a fairly high prevalence of alcohol abuse among men. Alcohol-related problems are especially high among middle-aged men. The outcomes suggest a low concordance between the concentration of PEth in the blood and the AUDIT score.
Aerodynamic Load Variation and Wind-Induced Vibration Analysis of Tower Cranes Under Full Wind Angles
Authors: Liu Qingjie , Zhang Ruijun , Sun Shuai , Zhang Jibin
Published: July 2024

When tower cranes are applied in coastal engineering, the wind-induced vibration under complex wind loads along the coast will be exceptionally obvious. It is increasingly important to explore the wind-induced vibration characteristics of different sections of tower cranes under full wind angles. This paper first establishes a three-dimensional numerical wind tunnel model that can be used for the simulation of tower cranes under full wind angles and analyzes the aerodynamic load variation of the tower crane under full wind angles. Secondly, the tower crane structure is divided into sub-regions, and the AR model method in the linear filtering method is used to simulate the three-dimensional wind speed time history. Further, the wind speed time history is applied to the finite element transient analysis, and based on the Newmark-beta method, the acceleration and displacement responses of different sections of the tower crane structure under fluctuating wind are systematically studied. Finally, the equivalent static wind load of different sections of the tower crane is evaluated by using the gust load factor method. The results indicate that the wind load of the tower crane exhibits an obvious three-dimensional effect, and the crosswind load cannot be ignored in the analysis of wind stability. The different sections of the tower crane structure show low-frequency vibration characteristics, and the low-frequency band is dominated by down-wind vibration, while the high-frequency band often experiences crosswind vibration. The amplification effect of the tower crane on fluctuating wind loads will increase with the increase of the height of the tower crane and the length of the jib, and the amplification effect on fluctuating wind loads in the crosswind direction is more obvious. The equivalent static wind load on the top of the tower crane reaches the maximum when the angle between the jib and the incoming wind is 60°.

In response to the challenges of weak fault characteristics and complex and variable working conditions of roll-ing bearings in strong noise environments, a diagnostic methodology is proposed. This method integrates a multi-scale residual neural network (MResNet) and a long short-term memory (LSTM) neural network to achieve fault diagnosis of bearings under both constant and variable rotational speed working conditions. First, complete an ensemble empirical mode decomposition with adaptive noise (CEEMDAN) that is applied for vibration signal denoising. Secondly, a dropout layer is introduced between multi-scale residual blocks to prevent net-work overfitting, and the powerful time series information capture ability of LSTM is combined to improve di-agnostic accuracy. Finally, experimental verification is conducted using constant and variable speed bearing data sets. The results show that the proposed approach maintains strong diagnostic capabilities when the rotat-ing speed conditions change, and the signal is heavily polluted by noise.

To investigate the damage characteristics of viscoelastic materials under various impact scenarios, this study presents a viscoelastic impact damage constitutive model that incorporates a material coefficient, a variable fractional-order differential operator, and a damage factor. Split Hopkinson Pressure Bar experiments are conducted under single-impact and repeated-impact conditions. The results indicate that nonlinear features in stress-strain curves at different stages, exhibiting prominent strain rate dependency near the stress peak point in the single-impact scenario. In the repeated-impact scenario, the stress peak points decrease as the impact times increase, resulting in a corresponding decline in the material's load-bearing capacity. Furthermore, strain rate escalates the strain rate increases with an increase in impact times, making the material more susceptible to deformation. Parameter fitting and Sobol sensitivity analysis utilizing experimental data from both scenarios have been employed to explore the effects and patterns of single-parameter and multi-parameter coupling on the model, accurately delineating their influence. The findings reveal a strong coupling relationship among various parameters of the viscoelastic impact damage constitutive model in multiple impact scenarios, showing higher sensitivity to fluctuations in the viscoelastic coefficient and damage factor. These analyses have demonstrated the accuracy of the viscoelastic impact damage constitutive model in capturing dynamic impact damage characteristics of viscoelastic materials across various scenarios.

Recent advancements in transfer learning have revolutionized predictive maintenance, enabling cross-domain generalization for components with varying characteristics and operating under different conditions. While traditional transfer learning approaches require labeled data in both source and target domains, unsupervised transfer learning strives for a more cost-effective alternative for which only labels are available in the source domain. This study investigates adversarial transfer learning between two different sensor modalities: vibration and acoustic. The goal is to enable bearing monitoring using microphones, which are, in general terms, cheaper and easier to deploy than vibration sensors; and without the need to label data in the target domain. The research goal is to identify the operating speed of a bearing testbed. The source domain data correspond to vibration measurements taken from an attached sensor, while the target domain uses a microphone array at distance. Artificial Neural Networks are used as the base architecture. Transferability is assessed with two unsupervised adversarial learning techniques: gradient reversal and deep correlation alignment. Their performance is compared to traditional supervised transfer learning via fine-tuning. Experimental results demonstrate that gradient reversal outperforms deep correlation alignment and is able to achieve results similar to those obtained with supervised transfer learning. These findings highlight the feasibility of speed identification using a microphone array and establish a baseline for future condition monitoring research with such sensors. Conclusion. These findings highlight the feasibility of speed identification using a microphone array and establish a baseline for future condition monitoring research with such sensors.

O estudo prático sobre campo magnético e como ele se relaciona com outras grandezas físicas são conteúdos que acabam sendo muito pouco abordados em sala de aula, apesar de ser uma área da Física que desperta a curiosidade dos estudantes. Com o intuito de minimizar esta falha, este trabalho utiliza a Sequência de Ensino Investigativo (SEI) para ensinar campo magnético através da elaboração de um dispositivo eletrônico baseado no efeito Hall utilizando Arduino. O dispositivo utilizado nesta pesquisa foi produzido no Laboratório de Pesquisa em Materiais para Aplicações em Dispositivos Eletrônicos (LABMADE), localizado no Centro de Ciências Integradas (CCI), no campus Araguaína da Universidade Federal do Norte Tocantins (UFNT). O equipamento foi aplicado no 3º ano do Ensino Médio (EM) de uma escola pública da periferia do município de Arapoema. O intuito desta aplicação foi familiarizar os estudantes com este conteúdo da Física e estimular o ensino através da relação entre teoria, tecnologia e prática. Os resultados sugerem que houve avanços nos conhecimentos de Física sobre campo magnético e no desenvolvimento dos cálculos matemáticos utilizados pelos alunos.
O AUTO RRELATO COMO JAZIGO DO SABER: REPENSANDO A PRÓPRIA PRÁTICA DOCENTE POR MEIO DOS ESTÁGIOS SUPERVISIONADOS
Authors: Leopoldino Armando
Published: July 2024

O departamento de História da Universidade Federal de Minas Gerais (UFMG), na reformulação curricular de 2009 a 2020, adotou sete disciplinas nas áreas de prática de ensino e de estágio supervisionado, ministradas tanto na Faculdade de Filosofia e Ciências Humanas quanto na Faculdade de Educação. O objetivo deste relato é refletir sobre minha própria experiência como aluno da primeira turma após essa reestruturação curricular e analisar em que medida ela impactou minha prática docente tanto durante a formação universitária quanto após ela. Como argumenta François Dosse em A História, o relato é um dos “jazigos do saber”, pois expande as formas de inteligibilidade de determinado evento. De um lado, trata-se de conferir sentido ao vivido a partir de inquietações do presente; de outro, abrem-se perspectivas para outros horizontes possíveis, na medida em que esses acontecimentos adquirem novos significados a partir de suas simbolizações pela narração. Defendo que os estágios supervisionados, pelo compartilhamento de experiências que eles propiciam, possibilitam uma ética docente diferente do ideário neoliberal de hiper-individualização e performance. Mais do que uma trajetória individual, o relato envolve modos de estar no mundo frente ao outro e atribuição de sentidos que (re)orientam a própria prática pedagógica.

Robotic coreless filament winding with natural fibres and bio-based resin systems offers potential solutions to address productivity and sustainability challenges in the construction sector. Their use in modular, prefabricated structures enables efficient, controlled, and eco-friendly
production, yielding high-quality building components with minimal production waste. Plant fibres like flax provide good strength and stiffness while requiring less non-renewable energy compared to traditional fibres like glass or carbon. This research focuses on the use and implementation
of flax fibre for coreless filament wound structural components by describing the conceptualization, design, fabrication, and assembly of a full-scale architectural demonstrator, the livMats Pavilion.
On the Interpretation of Cosmic Acceleration
Authors: Gaztanaga Enrique
Published: July 2024

The traditional way to define cosmic acceleration, denoted \( q \), relies on a comoving frame of reference within a 3D space-like coordinate system. This is the acceleration of the background metric in a particular frame rather than the actual acceleration between different observers on time-like geodesics. This traditional choice obscures the true physical processes, much like the Earth-centered model historically obscured the understanding of gravitational forces before the heliocentric shift. In this study, we introduce \( q_E \), a new metric defined by distances between causal events (i.e. acceleration between observes) in 4D null space. We compare \( q_E \) with \( q \) using observational data from supernovae (SN) and radial clustering of galaxies and quasars (BAO). Our results show that \( q_E \) offers a closer alignment with this data. Our analysis reveals that cosmic expansion, when viewed from the rest frame, is actually decelerating, confined by dynamics inside an Event Horizon, similar to conditions within a Black Hole interior. This indicates that \( \Lambda \) acts not as an agent of new dark energy or as a modification of gravity, but as a boundary term exerting an attractive force similar to a rubber band, which resists further expansion and prevents horizon crossing of events. We show how this interpretation of cosmic expansion as deceleration in the rest frame challenges conventional cosmological models and suggests that a reevaluation of these models is necessary.
