Authors: Gomes Letícia Kamille Vidal , Gomes Lívia Helena Vidal , Amaral Jhosefy Conde Martins , Vidal Patrícia Pereira , Gomes Igor Thiago dos Santos , Chaves Neto Antonio Maia de Jesus , Neto Abel Ferreira Gomes
Published: August 2023

Nesta pesquisa realizamos a dinâmica molecular das moléculas de Fipronil e glifosato interagindo individualmente com uma secção de nanotubo de carbono, a fim de verificar o desempenho dessa nanoestrutura no aprisionamento de agrotóxicos através de adsorção física. As simulações foram realizadas adotando o tempo de 50 pico segundos e foram repetidas para diferentes temperaturas na faixa de 273,15K – 323,15K. Observou-se que as moléculas de agrotóxico se mantiveram aprisionadas ao nanotubo de carbono durante todo o tempo de simulação, mesmo para diferentes temperaturas. Além disso, para cada simulação foram calculadas propriedades termodinâmicas (energias cinética e potencial, bem como a entropia dos sistemas), as quais permitiram verificar a estabilidade dos sistemas moleculares. Os resultados indicaram uma boa capacidade de adsorção física dos agrotóxicos na nanoestrutura, o que permite sugerir o nanotubo de carbono como possível matéria-prima para o desenvolvimento de sensores dos agrotóxicos Fipronil e Glifosato.

Authors: Cecilio Silva Wesley , Diniz Oliveira Raquel , Romagnoli Silveira  Lima Frederico
Published: August 2023

O consumo de energia de condicionadores de ar em edificações em regiões quentes e úmido se mostra relevante, em especial, naquelas não adaptadas ao clima. O presente trabalho teve por objetivo comparar o consumo e o rendimento de condicionadores de ar do tipo Split inverter e Split convencional. A análise foi realizada por meio de Simulações termo energéticas, utilizando o programa ©Energy Plus e o aplicativo, ©Open Studio. Condições operacionais e características técnicas dos sistemas foram embasadas na norma NBR 16555. Considerou-se uma Habitação de interesse social real como modelo referência, fundamentando em parâmetros de uso e ocupação do Regulamento técnico da qualidade para o nível de eficiência energética (RTQ-R). Obteve-se o modelo virtual da edificação e o comportamento operacional dos sistemas condicionadores de ar por meio de curvas de desempenho. Concluiu-se que, o uso de condicionadores do tipo inverter nas habitações não adaptadas ao clima, objeto da presente pesquisa se mostrou eficiente quando comparado a condicionadores convencionais. Assume-se que a substituição do equipamento split convencional por split inverter pode reduzir o consumo de eletricidade em até 41% ao ano, considerando os níveis de eficiência energéticas vigentes. Os condicionadores do tipo inverter conseguem minimizar o consumo de energia elétrica, o que tornaria acessível hipoteticamente a utilização de equipamentos mais eficientes as classes menos favorecidas.

Authors: Walger da Fonseca Raphaela , Mariano Pedro Oscar Pizzetti , Pereira Fernando Oscar Ruttkay
Published: August 2023

Muitos países adotam instrumentos regulatórios para a melhoria do desempenho das edificações e a qualidade luminosa é frequentemente abordada em seus escopos. Métodos simplificados facilitam a aplicação de tais instrumentos e a inteligência artificial tem se mostrado útil para esse fim. Assim, o objetivo deste trabalho é a propor um metamodelo, utilizando-se redes neurais artificiais, para verificar o desempenho luminoso de edificações residenciais, considerando o impacto do entorno construído no contexto da revisão da norma brasileira “ABNT NBR 15.575-1 Edificações habitacionais — Desempenho”. Para isto, adotou-se a base de dados simulados para a proposta de revisão da norma, contendo 36.000 casos que relacionam a influência de obstruções externas à edificação ao seu desempenho quanto à suficiência e uniformidade da luz natural. Assim, metamodelos de redes neurais artificias Perceptron Multicamadas foram treinados com dados das cidades de Curitiba, Brasília e Belém. A arquitetura das redes consistiu em 3 camadas, a de entrada, uma oculta e a de saída. Testaram-se aspectos de sua arquitetura e do agrupamento dos parâmetros de entrada, as variáveis da edificação, e de saída, ALNE200lx,50% e ALNE60lx,50%. O seu desempenho global foi considerado aceitável, com erro percentual médio inferior a 10%, sendo necessário o seu refinamento para a redução de discrepantes. Concluiu-se que as RNA podem ser uma alternativa como método simplificado para aplicação na norma, apontando-se como opções de refinamento do metamodelo a variação do algoritmo de aprendizagem, da partição dos conjuntos de treinamento e teste, e a ampliação do seu escopo com outras proporções e transmissões visíveis.
Análise do Impacto do Coeficiente de Pressão na Simulação de Ventilação Natural em Ambientes Internos
Authors: Carvalho Ferreira Camila , Amaral Daniel , Sad de Assis Eleonora
Published: August 2023

Para climas predominantemente quentes, a ventilação possui papel fundamental no conforto térmico ao retirar carga térmica dos ambientes e auxiliar nos processos de trocas térmicas do usuário. No entanto, os processos de ventilação natural não são elementares, demandando modelagens complexas para sua estimativa e verificação das exigências de conforto térmico. O objetivo deste trabalho é comparar diferentes estimativas de coeficiente de pressão de ventos para uma edificação: estimados pelo EnergyPlus e por simulação em CFD, assim como os respectivos impactos na renovação do ar dos ambientes. Foi estudada uma edificação educacional localizada em Palmas, TO, com uma geometria e soluções de ventilação natural complexas. Às taxas de renovação de ar obtidas com os coeficientes de pressão calculados pelo EnergyPlus e os coeficientes nulos, aplicou-se o indicador de desempenho desvio médio (MBD) para avaliar a sub ou superestimação em relação às taxas de renovação de ar resultante da simulação com os coeficientes de pressão obtidos pelo CFD. Os resultados mostram que apesar de o comportamento das curvas de renovação de ar ser similar com os coeficientes de pressão do CFD e do EnergyPlus, os resultados obtidos com o EnergyPlus tendem a subestimar as taxas de renovação de ar. Não é recomendado para edificações com geometria não retangular e/ou complexa o uso do EnergyPlus para o cálculo dos coeficientes de pressão e o uso de coeficientes nulos. Recomenda-se a obtenção dos coeficientes de pressão através de simulações com um CFD.
Introducing piezoceramics to suppress the multimode spacecraft payload vibrations
Authors: Ermakov V.Yu. , Tufan A. , Milanko K.N. , Firsyuk S.O.
Published: August 2023

Current trend in the spacecraft design lies in using large, complex and lightweight space structures to achieve increased functionality with the lower launch costs. Combination of large and lightweight designs results in these space structures becoming extremely flexible and acquiring the low frequency fundamental vibration modes. These modes could be used in various tasks, such as turning, guidance maneuvers and docking with the other spacecraft. Effective vibration suppression is a challenge for the spacecraft designers. One of the promising methods for solving this problem is introduction of the built-in piezoelectric elements as the actuators. The paper analyzes various control systems for the built-in piezoelectric elements to ensure the payload vibration protection. Experimental studies of these systems were carried out to determine the dynamics coefficient levels.
Design, development and approbation of the numerical technique in simulating the wing aeroelastic state based on the finite element and control volumes methods
Authors: Gunchin V.K. , Bolshikh A.A. , Ustinov B.E.
Published: August 2023

The paper considers a current trend in designing structural elements for the modern airliners. Calculation of the aerodynamic loads acting on the aircraft in flight is of primary interest at the initial design and development stages. Based on the experimental data, a CAD model was developed, and a computational grid for the CFD solver and the finite element model were constructed. The proposed technique for determining external loads on the airframe is based on the coupled solution of the aerodynamics and strength dynamic models. When using this technique, the serial data exchange between the solvers was actually implemented making it possible to simulate various periodic processes, including the structural vibrations. This work studies aerodynamic characteristics and eigenforms of the loaded wing using the example of the wing blowing calculated repetition in a cryogenic wind tunnel. The purpose of the work is to develop and test a technique for numerical simulation of the wing aeroelastic state, which allows performing calculations to determine the loads on both the lightly loaded elements and the critical units, including the wing box and the empennage. The results obtained testify to applicability of the developed technique at the transonic speeds, as well as a good convergence of the mathematical simulation results with the experimental data.

Published: August 2023

The paper considers options for constructing the GLONASS system high-orbit space complex in the high elliptical orbits, as the regional addition to the GLONASS orbital constellation. To assess navigation situation on the Earth’s surface, it proposes to consider the virtual consumer space for the navigation information. Civil consumers are considered as the navigation information consumers. An algorithm for calculating the values of spatial geometric factor and accessibility is presented. For various options in ballistic construction of the orbital constellation regional addition, numerical values were obtained of global geometric factor, global navigation accessibility and average geometric factor with two restrictions on the elevation angle: more than 5 degrees and more than 25 degrees. A proposal was formulated on the issue of the GLONASS system orbital constellation further development making it possible to improve positioning accuracy for the navigation information consumers.
Wolne Kozactwo i II Rzeczpospolita
Authors: Komar Vołodymyr , Szymanowicz Adam
Published: August 2023

Począwszy od XVI w. Kozacy byli jednym z narzędzi ekspansji Imperium Rosyjskiego. Służyli również do tłumienia antyrosyjskich i antycarskich powstań oraz buntów. Jeszcze w trakcie wojny domowej w Rosji Kozacy byli przez bolszewików poddawani represjom, a często i eksterminacji. Po zakończonej wojnie rozpoczął się proces rozkozaczania społeczności kozackiej i likwidacji jej odrębności. Nic zatem dziwnego, że Kozacy szukali sojuszników, w tym również w nowo odrodzonej Rzeczypospolitej. W latach 1919–1920 do Warszawy przyjeżdżali przedstawiciele wojsk kozackich w celu nawiązania współpracy wojskowej przeciwko Armii Czerwonej. W trakcie wojny polsko-bolszewickiej u boku Wojska Polskiego walczyło około 6000–7000 Kozaków. Po zakończonej wojnie tysiące Kozaków pozostały na emigracji w Polsce. Inne większe ich skupiska znajdowały się we Francji, w Niemczech, Jugosławii, a także w Czechosłowacji. Jednym z najaktywniejszych działaczy kozackich był Ignat Biłyj. Dzięki jego zabiegom władze polskie udzieliły wsparcia ﬁnansowego kozackiej akcji niepodległościowej, która uzyskała większą przychylność po dojściu do władzy marszałka Józefa Piłsudskiego. W 1927 r. w stolicy Czechosłowacji – Pradze powstał Komitet Wolnego Kozactwa złożony z Kozaków dońskich i kubańskich. Organizacja ta miała swym zasięgiem objąć możliwie najszerzej emigrację kozacką rozsianą w różnych państwach Europy, a nawet poza nią, w celu zjednoczenia jej do walki przeciwko Związkowi Sowieckiemu. Pomoc udzielana tej emigracji była jednym z elementów akcji prometejskiej zainicjowanej przez Józefa Piłsudskiego. Patronat nad akcją prometejską objął Oddział II Sztabu Generalnego / Głównego Wojska Polskiego (czyli organ wywiadu i kontrwywiadu wojskowego II Rzeczypospolitej), przy współpracy z Ministerstwem Spraw Zagranicznych i innymi instytucjami.

Authors: Spytek-Bandurska Grażyna
Published: August 2023

Celem artykułu jest przedstawienie podstaw prawnych funkcjonowania agencji pracy tymczasowej. Ich specyfika polega na tym, że są podmiotami gospodarczymi i zarazem należą do instytucji rynku pracy. Świadczone przez agencje usługi stanowią działalność regulowaną i podlegają wielu wymogom administracyjnym, które zostały szczegółowo omówione. Właściwością wyróżniającą agencje jest praca tymczasowa zaliczana do nietypowych form zatrudnienia ze względu na przypisane jej cechy charakterystyczne, głównie trójstronność konstrukcji prawnej i limitowany okres trwania, które zostały omówione w niniejszym artykule.
Zatrudnienie tymczasowe na podstawie umów cywilnoprawnych – ocena regulacji prawnej
Authors: Walczak Krzysztof
Published: August 2023

Zatrudnienie tymczasowe na podstawie umów cywilnoprawnych budzi poważne wątpliwości. Zdaniem autora agencje pracy tymczasowej, ze względu na swoją specyfikę, powinny zatrudniać jedynie na podstawie umów o pracę. Delegowanie do pracy na podstawie umów prawa cywilnego może być realizowane tylko w formule pośrednictwa. A więc agencja pracy tymczasowej staje się agentem osoby zatrudnionej i w jej imieniu ustala warunki kontraktu. Przy takim założeniu jakiekolwiek ograniczenia ustawowe dotyczące warunków zatrudnienia stanowią naruszenie swobody prowadzenia działalności gospodarczej wynikającej z Konstytucji. Dotyczy to także konieczności przekazywania związkom zawodowym informacji na temat warunków, na jakich ma być realizowana umowa o współpracę. Regulacje te sprawiają, że cywilnoprawny sposób wykonywania pracy staje się fikcją. Natomiast zatrudnienie może być uznane za naruszenie przepisów Kodeksu pracy.
Kilka refleksji na temat uprawnień kierowniczych w zatrudnieniu tymczasowym
Authors: Duraj Tomasz
Published: August 2023

Asumptem do przygotowania artykułu jest obowiązująca od 1 czerwca 2017 r. nowelizacja Ustawy zatrudnianiu pracowników tymczasowych, która dopuściła na szeroką skalę możliwość stosowania umów cywilnoprawnych w zatrudnieniu tymczasowym. Rozwiązanie to budzi szereg wątpliwości i problemów interpretacyjnych, także w kontekście uprawnień kierowniczych, jakie w konstrukcji za-trudnienia tymczasowego, do momentu uchwalenia tej nowelizacji, przysługiwały wobec wykonawcy zarówno agencji pracy tymczasowej, jak i pracodawcy użytkownikowi. Zasadniczym celem autora jest przedstawienie uprawnień kierowniczych w zatrudnieniu tymczasowym na trzech różnych płaszczyznach. Uprawnienia te zostały zaprezentowane: po pierwsze w pracowniczym zatrudnieniu tym-czasowym, po drugie w cywilnoprawnym zatrudnieniu tymczasowym, a po trzecie w outsourcingu pracowniczym, który funkcjonuje na styku z zatrudnieniem tymczasowym i często jest z nim łączony. Rozważania ujęte w opracowaniu pokazują, jak ważną rolę odgrywają uprawnienia kierownicze w kontekście dopuszczalności stosowania analizowanej tu nietypowej formy świadczenia pracy.
Zasada równego traktowania w zatrudnieniu tymczasowym
Authors: Strupp Liliana
Published: August 2023

Zasada równego traktowania pracowników tymczasowych ma swoje umocowanie w unijnej Dyrektywie 2008/104/WE w sprawie pracy tymczasowej. Realizacja tej zasady w polskim porządku prawnym jest gwarantowana zarówno przez ogólne przepisy prawa pracy odnoszące się do równego traktowania i niedyskryminacji pracowników, jak również przepisy Ustawy z dnia 9 lipca 2003 r. o zatrudnianiu pracowników tymczasowych, a w szczególności art. 15 ust. 1 tej ustawy. Obowiązek równego traktowania odnosi się do pracowników tymczasowych skierowanych do wykonywania pracy na rzecz pracodawcy użytkownika oraz pracowników bezpośrednio zatrudnionych przez tego pracodawcę na takim samym lub podobnym stanowisku pracy i dotyczy dwóch obszarów: „warunków pracy” i „innych warunków zatrudnienia”. Pojęcia te nie zostały wprost zdefiniowane w polskim porządku prawnym, a ich prawidłowe określenie i interpretacja stanowią podstawę właściwego rozumienia i realizacji przedmiotowej zasady.

Fuel systems of high power stationary engine
Authors: Kneba Zbigniew
Published: August 2023

The use of alternative fuels and, in the future, synthetic fuels has forced changes in the design of fuel supply systems in internal combustion engines. When operating a stationary engine at constant load, the possibility of using lean fuel mixtures appears. Selection of a precisely operating mixture ignition system requires changes in traditional fuel systems. The article presents the current designs of fuel supply systems and their properties. Attention was paid to operating parameters resulting in acceptable emissions of toxic exhaust gas components. Control systems that make the operation of the fuel system dependent on the properties of fuels are being developed.
Analysis of the potential of electro-waste as a source of hydrogen to power low-emission vehicle powertrains
Authors: Wesołowski Mateusz , Hamid Mohamad , Mońka Piotr , Janicka Anna
Published: August 2023

The decarbonisation of transport is one of the key aspects in the context of environmental protection. These emissions are particularly noticeable in highly urbanised areas, where the possibility of dispersal of harmful substances is much lower. A way to improve emission factors is the introduction of hydrogen vehicles. Burning hydrogen in engines significantly reduces emissions of harmful substances into the atmosphere compared to the combustion of conventional fuels used today. Hydrogen can be obtained by gasifying waste in a steam atmosphere. Electronic waste is a special type of waste characterised by a high degree of commingling, which makes it difficult to treat. The volume of this type of waste is increasing year on year. As a result of this process, we are able to obtain syngas. This gas, after separation processes, can be a source of hydrogen, an energy carrier that could prove crucial in low-carbon energy or transport applications. This paper presents the results of the gasification of electronic waste, the composition of the syngas obtained in the process and an assessment of the potential of this waste treatment technology to power means of transport.

Ley 2/2023, de protección de los informantes. Problemas aplicativos desde una perspectiva laboral
Authors: Puebla Pinilla Ana de la
Published: August 2023

La Ley 2/2023, de 20 de febrero, tiene como finalidad principal fomentar la cultura de la información y proteger a las personas que informan o denuncian la comisión de infracciones o delitos. La Ley tiene un gran impacto sobre el marco de las relaciones laborales. Por una parte, porque impone a las empresas la obligación, hasta ahora inexistente, de implementar un canal interno de información o denuncia para que, entre otras personas, sus propios trabajadores puedan comunicar delitos o infracciones que conozcan con motivo de su trabajo. Por otra, porque incorpora una bateria de medidas dirigidas a proteger a estas personas trabajadoras informantes o denunciantes frente a posibles represalias. El análisis de la Ley desde esta perspectiva laboral desvela la existencia de numerosos interrogantes y dudas interpretativas. En estas páginas se abordan algunas de estas cuestiones (sujetos protegidos, calificación jurídica de los actos de represalia, duración de la protección del informante, delimitación de las empresas obligadas a disponer de canal interno de denuncias, posibilidad o no de compartir un único canal entre las emrpesas de un grupo de sociedades, regimen jurídico del responsable del canal…), ofreciendo pautas para su resolución.

THE USE OF CONE BEAM COMPUTED TOMOGRAPHY TO EVALUATE OF RESULTS OF THE RAPID EXPANSION OF THE HARD PALATE WITH DENTAL ANOMALIES
Authors: Al'-Jafari Attba Kazvan Sami , Bazhenov Dmitry V. , Ul'yanovskaya Svetlana A.
Published: August 2023

The crowding of the permanent incisors with accompanying rotations or anterior cross bite is commonly seen during eruption of the permanent lateral incisors. When crowding is limited to a few millimeters, sufficient space may allow normal growth, but when the upper jaw is narrow and crowding exceeds this amount, rapid expansion of the hard palate may be an effective method. The purpose of this study was to study the method of cone beam computed tomography to evaluate the results of rapid palatal expansion in the narrowing of the upper dentition and the lack of space for incisors and the reaction of intact permanent molars, when fixing the apparatus on primary second molars in the absence of posterior cross bite. The study involved 20 children (age 7-10 years) who were treated with the Haas apparatus. The Haas apparatus was fixed on the upper second primary molars and on the primary canines. Cone beam computed tomography was performed before and after palatal suture rupture. A decrease in incisor crowding was found in all patients. The width between the permanent molars in the diameter has increased significantly, the distance between the tops of the roots of the upper permanent molars has increased more than between the crowns of the teeth. Application of the method shows the possibility of expanding the sky in the transverse direction. The use of a Haas apparatus attached to primary teeth in early mixed dentition in the absence of posterior cross bite is effective and provides a pronounced planned transverse growth of the jaw and can be indicated to expand the anterior part of the upper jaw to eliminate crowding of the upper incisors. With rapid expansion, there are favorable spontaneous changes in the palatal vertical position of the maxillary permanent molars in the opposite direction of expansion and there is the potential to mimic the expected natural transverse growth. Fixation of the apparatus used for this procedure on the primary molars and keeping the permanent molars unused means the prevention of periodontal damage, loss of attachment, demineralization and external resorption of the roots of permanent molars.

Periodontitis is a disease that progresses with age and contributes to the biological aging of the dentition. One of the reasons for this phenomenon is the aging of human gum fibroblasts. Low-intensity laser therapy stimulates the release of growth factors from fibroblasts and their division. The aim of the study was to determine the number, proliferative activity and apoptosis of gingival fibroblasts in people without signs of periodontal inflammation, with chronic periodontitis and after laser therapy. We used biopsy material obtained for periodontal, surgical, orthopedic and orthodontic indications under infiltration anesthesia in two age groups of patients aged 20–40 and 41–60 years. Cell markers Ki-67 and p53 were detected by immunohistochemical methods, the total number of gingival fibroblasts was estimated by staining with hematoxylin and eosin. The results of the conducted studies showed that the number of fibroblasts in the connective tissue lamina of the gums has age-related features. In young people from 20 to 40 years, the number of fibroblasts in gum preparations is 1,12 times higher than in people aged 41–60 years. Among the reasons for the decrease in the number of gingival fibroblasts is a decrease in their proliferative activity and activation of the proapoptotic p53 protein with age. Chronic periodontal inflammation leads to a significant increase in the number of fibroblasts, regardless of the age of the subjects. Fibroblast proliferation and p53 protein expression were more sensitive to microbial inflammation in patients aged 41 to 60 years compared to younger patients. Three-fold laser exposure had a differentiated modulating effect on the state of the gingival fibroblast population, depending on the age of the patients, the number of gingival fibroblasts was restored to the levels characteristic of healthy people, and this was observed only in the group of young patients. Thus, the number of fibroblasts in the human gingival connective tissue lamina changes with age, under conditions of inflammation and under the influence of a diode laser, which must be taken into account in dental practice.

[Purpose] To investigate the effects of a combination of running and food restriction on the chemical properties of the bone in young female rats using Raman spectroscopy. Furthermore, we investigated whether the chemical property parameters correlated with the bone-breaking strength.[Methods] Female Sprague–Dawley rats (7 weeks old) were randomly divided into four groups: sedentary and ad libitum feeding (SED, n = 8), voluntary running exercise and ad libitum feeding (EX, n = 8), sedentary and 30% food-restricted (SED-FR, n = 8), and voluntary running exercise and 30% food-restricted (EXFR, n = 8). The experiment was conducted for a period of 12 weeks. Four parameters measured by Raman spectroscopy were used to evaluate the bone chemical quality.[Results] Exercise and restriction had significant interactions on the mineral to matrix ratio. The mineral- to-matrix ratio in the SED-FR group was significantly higher than that in the SED group and significantly lower in the EX-FR group than that in the SED-FR group. Running exercise had significant effects on increasing the crystallinity and carbonate-to-phosphate ratio. In the ad libitum intake condition, there were significant positive correlations between breaking energy and crystallinity (r = 0.593) and between breaking energy and carbonate-to-phosphate ratio (r = 0.854).[Conclusion] Our findings show that running exercise and food restriction, alone or in combination, affect the chemical properties of bone. Furthermore, under ad libitum intake conditions, positive correlations were found between the breaking energy and crystallinity, or carbonate-to-phosphate ratio.
Ibuprofen and diclofenac in the marine environment - a critical review of their occurrence and potential risk for invertebrate species
Authors: Blasco Julián , Trombini Chiara
Published: August 2023

The presence of the two main non-steroidal anti-inflammatory drugs (NSAIDs), diclofenac (DCF) and ibuprofen (IBU), in marine and estuarine systems has been reported. Although the available information about the toxicity of these compounds in aquatic organisms has increased in recent years, the database about marine organisms, specifically invertebrates, is limited. Consequently, the assessment of potential risks posed by these compounds to aquatic species should be improved, given their relevance for aquatic life and the trophic chain. To fill this gap, we analyze the potential risk of IBU and DCF in marine invertebrates. To assess the risk, the database was built with available information from the scientific literature about the occurrence, bioaccumulation, and toxicity of both compounds in the estuaries and marine environments. Risk assessment of both compounds in these environments is scarce and based essentially on their acute toxicity. Data compiled in this review, including environmental concentrations and toxicity thresholds, were used to calculate risk quotients and classify the risk for invertebrate communities in coastal areas with different contamination levels. The results indicated a higher risk for DCF than IBU. Additionally, the simultaneous presence of the two NSAIDs in the aquatic environment increases the risk for exposed organisms. The use of classical methods (e.g., biochemical markers, gene expression), new approaches (e.g., adverse outcome pathway, AOP), and omic techniques has contributed to understanding the underlying toxicity mechanisms and improving the risk assessment. However, in a global change scenario involving multiple drivers and pressures such as ocean acidification, heat waves, climate change, etc., the risk assessment for these emerging pollutants needs improvement. This can be achieved by increasing our knowledge about the metabolic pathway and biotransformation routes of these compounds in marine species and understanding how these changes can affect the bioaccumulation, toxicity, fate, and behavior of both NSAIDs.

Проаналізована ефективність поглинання електромагнітного (ЕМ) випромінювання компонентами мікрохвильових екрануючих композитів. У поглинаючому матеріалі ЕМ-хвиля втрачає свою енергію під час її взаємодії з молекулярною та електронною структурою матеріалу. Розглянуті механізми поглинання хвиль у діелектриках, напівпровідниках, магнетиках та металах з урахуванням розмірних ефектів. Встановлено, що поглинальна здатність провідникових і магнітних наповнювачів композитів знижується в міру збільшення частоти, тоді як високопоглинаючі діелектрики збільшують свою поглинальну здатність зі зростанням частоти. Даються рекомендації щодо вибору поглинаючих компонентів екрануючих композитів призначених для різних діапазонах частот.

Authors: Kudryashova D. , Rozhkova Z. , Mayorova M.
Published: August 2023

The article analyzes the current state of Russian-Uzbek relations. The main focus is on the main areas of cooperation: economic, political, cultural, military-technical. The formation of the interests of bilateral relations under the influence of internal and external factors is considered, since without understanding the goals, objectives and position of each individual state, it is difficult to count on the development of the optimal foreign policy course and concept of cooperation. Despite some difficulties, at this stage the relations between the Russian Federation and the Republic of Uzbekistan are becoming increasingly consistent, stable and pragmatic. The legal basis for cooperation is being improved, a common educational, cultural and technological space is being formed, logistical corridors are being developed, and measures are being actively shaped to prevent and eliminate security threats in the region.
Digital Dimension of the EAEU Socio-Economic Integration
Authors: Udovenko I.
Published: August 2023

The article analyzes the priorities of socio-economic development of the digital strategies of the Eurasian Economic Union (EAEU) member states in the context of implementing the digital agenda. The author concludes that the formation of disparate national public administration platforms limits the possibilities for integration. Along with technological limitations, the main obstacle to the creation of a single digital space of the EAEU is the difference in approaches to socio-economic policy, which prevents one of the key goals of the Union – to develop a common labor market. The purpose of this article is to identify possible “assembly points” of digital tools for the development of the EAEU labor market as the basis for their socio-economic integration.
