Scattering Field Intensity and Orbital Angular Momentum Spectral Distribution of Vortex Electromagnetic Beams Scattered by Electrically Large Targets Comprising Different Materials
Authors: Sun Minghao , Liu Songhua , Guo Lixin
Published: February 2024

In this study, we obtained the intensity and orbital angular momentum (OAM) spectral distribution of the scattering fields of vortex electromagnetic beams illuminating electrically large targets composed of different materials. We used the angular spectral decomposition method to decompose a vortex beam into plane waves in the spectral domain at different elevations and azimuths. We combined this method with the physical optics algorithm to calculate the scattering field distribution. The OAM spectra of the scattering field along different observation radii were analyzed using the spiral spectrum expansion method. The numerical results indicate that for beams with different parameters (such as polarization, topological charge, half-cone angle, and frequency) and targets with different characteristics (such as composition), the scattering field intensity distribution and OAM spectral characteristics varied considerably. When the beam parameters change, the results of scattering from different materials show similar changing trends. Compared with beams scattered by uncoated metal and dielectric targets, the scattering field of the coating target can better maintain the shape and OAM mode of beams from the incident field. The scattering characteristics of metal targets were the most sensitive to beam-parameter changes. The relationship between the beam parameters, target parameters, the scattering field intensity, and the OAM spectra of the scattering field was constructed, confirming that the spiral spectrum of the scattering field carries the target information. These findings can be used in remote sensing engineering to supplement existing radar imaging, laying the foundation for further identification of beam or target parameters.

Published: February 2024

Walking speed is a significant aspect of evacuation efficiency, and this speed varies during fire emergencies due to individual physical abilities. However, in evacuations, it is not always possible to keep an upright posture, hence atypical postures, such as stoop walking or crawling, may be required for survival. In this study, a novel 3D passive vision-aided inertial system (3D PVINS) for indoor positioning was used to track the movement of 20 volunteers during an evacuation in a low visibility environment. Participants’ walking speeds using trunk flexion, trunk–knee flexion, and upright postures were measured. The investigations were carried out under emergency and non-emergency scenarios in vertical and horizontal directions, respectively. Results show that different moving directions led to a roughly 43.90% speed reduction, while posture accounted for over 17%. Gender, one of the key categories in evacuation models, accounted for less than 10% of the differences in speed. The speeds of participants under emergency scenarios when compared to non-emergency scenarios was also found to increase by 53.92–60% when moving in the horizontal direction, and by about 48.28–50% when moving in the vertical direction and descending downstairs. Our results also support the social force theory of the warming-up period, as well as the effect of panic on the facilitating occupants’ moving speed.
Evaluation of Welded Lap Joints Using Ultrasonic Guided Waves
Authors: Altammar Hussain , Faseeulla Khan Mohammad
Published: February 2024

Welded lap joints play a vital role in a wide range of engineering structures such as pipelines, storage tanks, pressure vessels, and ship hulls. This study aims to investigate the propagation of ultrasonic guided waves in steel welded lap joints for the baseline-free inspection of joint defects using the mode conversion of Lamb waves. The finite element method was used to simulate a single lap joint with common defects such as corrosion and disbonding. To identify the propagating wave modes, a wavenumber–frequency analysis was conducted using the 2D fast Fourier transform. The power loss of the transmitted modes was also determined to identify damage in the lap joints. The results indicate that the A0 incident in pristine conditions experienced significant transmission losses of about 9.5 dB compared to an attenuation of 2.8 dB for the S0 incident. The presence of corrosion was found to reduce these transmission losses by more than 28%. In contrast, introducing disbonding in the lap joint increased the transmission loss of the S0 incident, while a negligible loss was observed for the A0 incident. The mode-converted S0 (MC-S) and mode-converted A0 (MC-A0) incidents were found to exhibit a unique sensitivity to the presence of corrosion and disbonding. The results indicate that MC-S0 and MC-A0 as well as Lamb mode incidents interact differently in terms of corrosion and disbonding, providing a means to identify damage without relying on baseline signals.
Multifunctional Polypyrrole-Based Textile Sensors for Integration into Personal Protection Equipment
Authors: Gleissner Carolin , Mayer Paul , Bechtold Thomas , Pham Tung
Published: February 2024

Integrated safety sensors for personal protection equipment increasingly attract research activities as there is a high need for workers in delicate situations to be physically monitored in order to avoid accidents. In this work, we present a simple approach to generate thin, homogeneous polypyrrole (PPy) layers on flexible textile polyamide fabrics. PPy layers of 0.5–1 µm were deposited on the fabric, which thus kept its flexibility. The conductive layers are multifunctional and can act as temperature and gas sensors for the detection of corrosive gases such as HCl and NH3. Using three examples of life-threatening environments, we were able to monitor temperature, atmospheric NH3 and HCl within critical ranges, i.e., 100 to 400 ppm for ammonia and 20 to 100 ppm for HCl. In the presence of HCl, a decrease in resistance was observed, while gaseous NH3 led to an increase in resistance. The sensor signal thus allows for distinguishing between these two gases and indicating critical concentrations. The simple and cheap manufacturing of such PPy sensors is of substantial interest for the future design of multifunction functional sensors in protective clothing.
Design and Implementation of a Linear Active Disturbance Rejection Control-Based Position Servo Control System of an Electromotive Valve for Exhaust Gas Recirculation
Authors: Cheng Xin , Yin Jianzhong , Li Xiaokang , Zhou Rougang , Fu Chong
Published: February 2024

An exhaust gas recirculation (EGR) valve is used to quickly and dynamically adjust the amount of recirculated exhaust gas, which is critical for improving engine fuel economy and reducing emissions. To address problems relating to the precise positioning of an electromotive (EM) valve under slowly varying plant dynamics and uncertain disturbances, we propose a servo control system design based on linear active disturbance rejection control (LADRC) for the EGR EM valve driven by a limited angle torque motor (LATM). By analyzing the structure of the LATM and the transmission, the dynamic model of the system is derived. In addition, to solve the problems caused by slowly varying plant dynamics and uncertain disturbances, we combine the effects of uncertain model parameters and external disturbances as the total disturbance, which is estimated in real time by an extended state observer (ESO) and then compensated. In addition, accurate angular information is obtained using a non-contact magnetic angle measurement method, and a high-speed digital communication channel is established to help implement a closed-loop position control system with improved responsiveness and accuracy. Simulation and experimental results show that the proposed servo system design can effectively ensure the precision and real-time performance of the EM valve under slowly changing plant dynamics and uncertain disturbances. The proposed servo system design achieves a full-stroke valve control accuracy of better than 0.05 mm and a full-stroke response time of less than 100 ms. The controlled valve also has good robustness under shock-type external disturbances and excellent airflow control capability. The repeatability of the airflow control is generally within 5%, and the standard deviation is less than 0.2 m3/h.

Accessibility to Andrology Medical Devices in Arab-Muslim Countries
Authors: Jamali Mounir
Published: February 2024

Highlighting the restricted access to andrology medical devices in Arab Muslim countries, where unjust associations with sexual instruments lead to prohibitions, this commentary underscores the challenges in providing appropriate medical care for andrological conditions. Despite the crucial role of devices like penile extenders, vacuum devices, and vibrators in treating conditions such as Peyronie’s disease and erectile dysfunction, cultural and religious biases condemn them in certain regions. This lack of understanding deprives many patients of andrological treatments, limiting therapeutic options and equitable healthcare access. The commentary advocates for urology societies to raise awareness, engage policymakers, and use media to distinguish these devices from sex toys, emphasizing their medical nature for the benefit of patients.
Time Preferences, Land Tenure Security, and the Adoption of Sustainable Land Management Practices in Southeast Nigeria
Authors: Olumba Cynthia Nneka , Garrod Guy , Areal Francisco Jose
Published: February 2024

Sustainable land management (SLM) practices are important for tackling agricultural land degradation. This study investigates the association between farmers’ time preferences and their adoption of SLM practices (agroforestry, terracing, and land fallow practices) with intertemporal benefits, and further documents the moderating role of land tenure security in this relationship. The analysis in the paper is based on data from a survey of 480 farmers in south-east Nigeria, complemented by semi-structured interviews. Farmers’ time preferences were elicited using both a survey and experiments with hypothetical payouts. Land tenure was conceptualised as a composite concept to suit the legally pluralistic context of the study area. This study found that many of the sampled farmers have high discount rates. The result further shows that farmers’ time preferences are negatively associated with their adoption of agroforestry and land fallow practices. Moreover, the result shows that both legal and de facto tenure security encourage the adoption of SLM practices. Other factors influencing the adoption of SLM practices include gender, household size, education, credit constraints, marital status, risk attitude, farming experience, and farm characteristics (e.g., erosion problems and steepness of slope). Furthermore, this study found that the security-enhancing effect of land tenure security (de facto) can alleviate the negative influence of time preferences on farmers’ adoption of SLM practices. The findings suggest that farmers with higher discount rates, who have secure tenure rights to land, are more likely to adopt SLM practices, compared to similar farmers without tenure security.
A Review of Renewable Energy Communities: Concepts, Scope, Progress, Challenges, and Recommendations
Authors: Ahmed Shoaib , Ali Amjad , D’Angola Antonio
Published: February 2024

In recent times, there has been a significant shift from centralized energy systems to decentralized ones. These systems aim to satisfy local energy needs using renewable resources within the community. This approach leads to decreased complexity and costs, improved efficiency, and enhanced local resilience and supports energy independence, thereby advancing the transition toward zero carbon emissions. Community energy plays a pivotal role globally, particularly in European countries, driven by citizen engagement in generating power from renewable sources. The European Union, known for its focus on social innovation and citizen participation, recognizes the essential role of energy communities in its latest energy strategy. The concept for creating local energy communities or community-based energy projects has gained worldwide attention, demonstrating the economic, environmental, and efficiency benefits for using renewable energy sources. However, there is a noticeable gap in research covering all the updated aspects of renewable energy communities. This article provides an in-depth review of energy communities, especially renewable energy communities, exploring their concepts, scope, benefits, and key activities. It also sheds light on their progress by presenting results and analyses. Some countries have shown significant advancement, others are in the initial stages, and a few have partially adopted REC implementation according to the Renewable Energy Directive II. Additionally, it discusses the main challenges and potential recommendations to enhance the growth of renewable energy communities. This work is a valuable resource, emphasizing the importance of citizen involvement and offering insights into various aspects of community energy for sustainable energy transition. It also provides practical insights and valuable information for policymakers, researchers, industry professionals, and community members who are keen on promoting sustainable, community-driven energy systems.

Published: February 2024

This paper aims to provide a contribution to understanding the role of sludge macro-components (lipids, proteins and carbohydrates) on the yield/quality of bio-crude obtained via hydrothermal liquefaction (HTL). This was pursued by analysing the HTL process of real sludges and the mixtures thereof at different compositions, a topic that has been explored in a very limited way in the pertinent literature. The HTL experiments were run with municipal sludge, tannery sludge and a mixture of them in 25:75, 50:50 and 75:25 weight ratios in a batch reactor at 350 °C and for different residence times. The outcomes for a single sludge showed a greater bio-crude yield for the municipal one (42.5% at 10 min), which is linked to its significant carbohydrate content. The results obtained from the sludge mixtures suggested that a carbohydrate-to-protein mass ratio of 2:1 would maximise the bio-crude yield (average value of about 38%). Moreover, LC-MS and NMR analyses highlighted that the mixed sludges contributed to the formation of a higher number of compounds after the HTL treatment, with respect to the pure municipal or tannery sludge, with an increase in amine, alcohols and aromatic compounds.
Special Discrete Fuzzy Numbers on Countable Sets and Their Applications
Authors: Qin Na , Gong Zengtai
Published: February 2024

There are some drawbacks to arithmetic and logic operations of general discrete fuzzy numbers, which limit their application. For example, the result of the addition operation of general discrete fuzzy numbers defined by the Zadeh’s extension principle may not satisfy the condition of becoming a discrete fuzzy number. In order to solve these problems, special discrete fuzzy numbers on countable sets are investigated in this paper. Since the representation theorem of fuzzy numbers is the basic tool of fuzzy analysis, two kinds of representation theorems of special discrete fuzzy numbers on countable sets are studied first. Then, the metrics of special discrete fuzzy numbers on countable sets are defined, and the relationship between these metrics and the uniform Hausdorff metric (i.e., supremum metric) of general fuzzy numbers is discussed. In addition, the triangular norm and triangular conorm operations (t-norm and t-conorm for short) of special discrete fuzzy numbers on countable sets are presented, and the properties of these two operators are proven. We also prove that these two operators satisfy the basic conditions for closure of operation and present some examples. Finally, the applications of special discrete fuzzy numbers on countable sets in image fusion and aggregation of subjective evaluation are proposed.

Published: February 2024

The article reveals the mechanism of the reverse impact of anti-Russian sanctions of 2022–2023 on the economics of the countries-sanctioners with justification of the reasons for their falling into the Russian big country trap. The leading directions of Russian negative infl uence under the infl uence of a certain boomerang eff ect on the national economies of the countries of the Western coalition led by the United States are shown. The main among them is the development of an unprecedented fuel and raw materials crisis here, intensifying the real danger of another drop of the "Golden Billion" countries into a stagflation funnel similar to the events of half a century ago. The threat of going into a state of economical recession for a number of Western countries is associated with the irrevocable loss of a vast and promising national market by their companies while it is impossible to quickly fi nd alternative sales markets. The increasing risks of accelerating the process of de-dollarization and de-euroization of the global economy are regarded in the work as a direct result of the freezing of the Bank of Russia’s international reserves. The European Union, the macroregion of the world economics, is considered most aff ected by its own restrictions, while their main initiator, the United States, mostly manages to avoid the economic losses associated with them. The conclusion is that the destructive influence of restrictions against Russia on the short-term economical dynamics of Western countries is combined with the inevitable exhaustion of the big country effect already in the mid-term, which dictates the need for the Russian state to maximize the use of time to implement the overdue structural reforms.

Published: February 2024

Foreign trade in goods is one of the most important tools for the development of the Russian economy. On the one hand, foreign trade meets the country’s needs for various goods, the production of which is absent or does not fully satisfy domestic demand. On the other hand, foreign trade allows Russian goods to gain access to international markets, diversifying sales channels. It is important to note that foreign trade activities are impossible without a developed international settlement mechanism, which provides buyers of goods with the opportunity to pay sellers, and sellers with the opportunity to receive foreign exchange earnings for goods supplied. According to established practice in world trade, most international payments are carried out using two reserve currencies: the US dollar and the euro. At the same time, in relation to Russian foreign trade, the use of the US dollar and euro in international payments has become extremely difficult due to the introduction by Western countries of a large number of anti-Russian sanctions, which also affected the sphere of international fi nance. The article analyzes the problems of implementing international payments, based on the results of which specifi c proposals were developed that will contribute to the development of Russian foreign trade. The problems of international payments caused by the introduction of anti-Russian sanctions by Western countries in the fi eld of international fi nance can be solved through an active transition to the national currencies of counterparty countries when concluding international purchase and sale transactions. When trading with countries with which Russia applies a free trade regime, it is advisable to use the Russian ruble as the currency of international settlements. In addition, in order to speed up international payments, it is proposed to switch to electronic document management, which implies the signing of international sales and purchase agreements and the exchange of transaction documents in electronic form using an electronic signature.

The article discusses theoretical issues regarding the personnel reserve, the formation of the "Random Forest" DL model for the selection of applicants for the Russian federal reserve in modern conditions. The relevance of the study lies in the fact that in modern conditions artifi cial intelligence systems based on cognitive modeling, the use of artifi cial intelligence and the formation of digital ecosystems are increasingly being used. The scientific novelty lies in the fact that in the study conducted, a deep learning model DL-model "Random Forest" was formed, which allows the selection of applicants when forming the federal reserve. The practical significance of the study is that the results obtained can be recommended for implementation in practice to provide support for management decisions in the formation of the federal reserve. The cognitive model was developed in the GraphViz environment using a semantic frame network in the form of graphs in the DOT programming language. A questionnaire was developed to identify the qualitative characteristics of applicants, which made it possible to create a "Random Forest" DLmodel dataset. The criterion for the success of the predictive properties of the DL model was the value of the average forecast error (MAE). The proposed DL model uses the best decision tree, which has optimal hyperparameter settings, for example, the depth of the tree is six layers, the number of estimators (trees) in the ensemble is ten. In the experiment, the hyperparameters of the neural network did not change; the input parameters to various trees were selected randomly by the algorithm.
Derechos culturales y afrodescendencia: alcances de la experiencia del pueblo tribal afrochileno
Authors: Antón Sanchez John Herlyn
Published: February 2024

En el año 2022 los ciudadanos de Chile rechazaron en dos ocasiones propuestas de reforma a la actual constitución, vigente desde los años 80s. El proyecto de reforma constitucional proponía que la población afrodescendiente de Chile fuera reconocida como pueblos afrodescendientes tribales y poseedores de derechos culturales. Esta situación generó un debate sobre la conveniencia de este posible reconocimiento. En este artículo exploramos el alcance que para el derecho internacional pudieran tener los derechos culturales a la afro descendencia de las Américas. Principalmente se explora: ¿Qué significan estos derechos en el contexto de pueblos étnica y racialmente determinados como los afrodescendientes?, ¿Qué pudiera aportar esta caracterización de derechos en la coyuntura del proyecto de declaración universal de derechos de los descendientes de africanos en el mundo, que actualmente discute las Naciones Unidas?

Authors: Özen Doğukan , Bıçakcı Nail Mert , Salgırlı Demirbaş Yasemin
Published: February 2024

This study examined the factors influencing pet attachment by investigating attachment dimensions and exploring the relationship between demographic factors and pet attachment. The study utilized the Pet Attachment Questionnaire (PAQ) to assess the level of attachment between pet owners and their animals. A demographic questionnaire was also administered to gather socio-cultural, economic, and health-related data from pet caretakers. Confirmatory factor analysis was applied to confirm the scale factor structure. Hypothesis testing procedures were used to reveal the relationship between the demographic characteristics of the participants and the attachment relationships. The study involved 304 volunteers who visited the animal hospital at Ankara University, Faculty of Veterinary Medicine, Türkiye. The findings revealed significant impacts of various factors on attachment dimensions, including age, household income, participant and household member anxieties and traumas, number of pets owned, pet health, and previous pet ownership. These results contribute to our understanding of the complex dynamics that shape the attachment between humans and animals. Further research is needed to understand the underlying mechanisms and potential interactions among these factors, advancing our knowledge of human-pet attachment.

Les Phéniciens dans l'historiographie romaine et la sous-évaluation du rôle joué par les influences sémitiques dans la République avant les guerres puniques
Authors: Camous Thierry
Published: February 2024

Rome connut dans sa plus haute histoire une influence phénicienne notable. Les témoignages archéologiques révèlent les traces du passage des commerçants phéniciens dans un Latium ancien idéalement situé entre Étrurie et Campanie. Les plus anciens cultes de Rome et des environs -Satricum, Pyrgi -ont été, à l’image de l’Hercule de l’ara Maxima, fortement influencés par les Phéniciens. De même on ne doute plus guère aujourd’hui de l’historicité des traités romano-carthaginois. L’historiographie romaine qui se forge avec les premiers annalistes qui ont connu la guerre d’ Hannibal a consciemment évincé de la «vulgate » l’élément phénicien, alors même qu’elle n’a pu ignorer l’importance de son influence sur les origines de Rome et la première histoire de l'Vrbs.

The coincidence of data which relate to Socrates and are present in the works of Aristophanes, Xenophon and Plato may configure a historic basis of Socrates’ personality and to demonstrate that Aristophanes ’Socrates responds to a historical reality in comic code. Aristophanes has built a figure that is deformed by the conventions of the comical genre, but that is established upon a historical base, which coincides in its essential traits with the testimonies of various genres and epochs. Aristophanes’ construction of Socrates is not negative ; it was wrongly interpreted by the audience and also largely so by the critics.

L’Odyssée d’Homère se base-t-elle sur une île réelle ou imaginaire ? Malgré le fait que la description que le poète en a fait (en IX, 19-26) ait longtemps paru énigmatique, de récentes recherches sur la péninsule de Paliki à Képhallénie (www.odysseus-unbound.org/results.html) permettent de penser plutôt à un endroit existant réellement. Ceci révèle la probabilité excitante qu’un lieu tel que la Porcherie d’Eumée ait également existé à la fin de l’Âge du Bronze et souligne l’importance de la connaissance détaillée qu’ils avaient de leur géographie locale.

According to his friend Hermogenianus, Augustine «defeated » the Academicians in the Contra Academicos. According to his personal opinion, the real achievement of the treatise is solely to have demonstrated that it is probable that the wise man has a share in truth and to have revived the hope of finding it. Augustine’s belief that New Academicians pretended to be sceptics, together with his concept of philosophy, provides the explanation for such a judgement.

Klaus Tausend's Verkehrswege der Argolis postulates that archaeological evidence should be assessed independently of ancient texts. However concerning the reconstruction of the criss-crossing network of ancient roads in the Peloponese, Pausanias' description of Greece is in a class of its own. In relation to some topographical problems, a re-reading of the Periegesis in the the light of archaeological evidence leads to find alternative solutions to the explanation of the roads and the borders they run across.

Digital Teaching Competence and Educational Inclusion in Higher Education. A Systematic Review
Authors: Zarceño García de Soriano Ada Janeth , Agreda Montoro Miriam , Ortiz Colón Ana María
Published: February 2024

This article presents a systematic review of the literature with the aim of providing an updated framework for the scientific production developed in the field of digital competence and inclusive education in Higher Education, as indexed in the Web of Science (WoS) and SCOPUS databases. Twenty-one scientific articles published between 2016-2023 were included and analyzed, with no temporal cohort established. The search matches yielded a first document of the topic of study in 2016 in the Social Sciences Citation Index. The results obtained on the conceptual structure of the analyzed documents were carried out through a multiple correspondence analysis (MCA) observing the existence of two dimensions composed of three clusters. Cluster one was composed of studies on digital competence, virtual learning environments, digital divide, and functional diversity, among others. Cluster two comprised studies carried out on digital tools and competencies, inclusive education, educational processes, and digital strategies; while cluster three was made up of educational inclusion related to interculturality and digital competence. Among its limitations, there were aspects related to the heterogeneity of the studies, which make it difficult to compare the data, and the sample and size of the study, which makes the results obtained and the generated data have a lower percentage of generalization compare to studies that use larger simples. This study has implications for researchers and Higher Education institutions interested in research on digital competence for inclusive education, with the possibilities of digital competence for inclusive education being established from the studied variables, allowing teachers to adapt and personalize learning to meet individual student needs. All of this is in line with the goals of the 2030 Agenda, concerning the empowerment of citizens and the digitization of public services to ensure the population's access to such services via the internet.

Socio-affectiveness and alternative figures of care for girls, boys and adolescents in Argentine legal praxis
Authors: Notrica Federico Pablo
Published: February 2024

Both the legislation and the doctrinal and jurisprudential creation have begun to recognize the notion of socio-affectivity as a structuring element of family relationships among its members, often granting it primacy over the biological bond or relationships derived from kinship. Although affection has always been a constitutive component of human relations, the classical approach refused and refuses to recognize in it a source of Law and, as such, share the halo of legitimacy that kinship ties have enjoyed since ancient times. This resistance was able to generate many problems in reality, since the lack of legal recognition in some of the figures ruins the advances in the field of human rights. A clear example in Argentine legislation turns out to be the contents of articles 611, 643 and 657 of the Civil and Commercial Code on the prohibition of de facto guardians except the kinship bond between parents and guardians; or the delegation of the exercise of parental responsibility and the granting of custody of a child or adolescent, limiting it only to a relative. Well, while this legal limit occurs, reality prevails and, in some cases, the affective bond overlaps the biological one, owing value to the guiding principle of the best interest of the child to solve the problem raised. From this, the present work will try to demonstrate, through the analysis of the jurisprudence, the solutions reached that combine said guiding principle with the notion of socio-affectivity.

Politicidad y performatividad en las prácticas gráficas
Authors:   , Valente Alicia Karina
Published: February 2024

La presente tesis se propone estudiar las relaciones entre gráfica, politicidad y performatividad a partir de una serie de prácticas colectivas, y los modos en que intervienen en la esfera pública, con el análisis de casos de la ciudad de La Plata, Argentina, en el periodo 1993-2017. Esta investigación se propone evidenciar una amplia y compleja trama local donde se vinculan –en diferentes grados y formas– artistas, colectivos artísticos, movimientos políticos y sociales, y ciudadanos en general, a partir de una serie de objetos de estudio significativos. En ese entramado, a su vez, puede reconocerse la inserción de los mismos en una genealogía amplia de gráfica colaborativa entendida como una red de prácticas caracterizadas por su voluntad de intervención y la puesta en discusión de los modos consagrados de producción y circulación del arte. La hipótesis que sustenta esta investigación sostiene que desde la gráfica artística se promovieron prácticas colaborativas que contribuyeron de formas diversas a crear comunidad. De forma particular, se considera a la ciudad de La Plata como un terreno particularmente connotado para este tipo de prácticas cuya presencia en el espacio público urbano fue creciendo de forma exponencial en el trascurso del periodo que abarca esta investigación. En esa línea, a lo largo de esta tesis se propone identificar y analizar en algunos proyectos locales las estrategias de agenciamiento desarrolladas para la creación de comunidades. De igual forma, y en relación con lo mencionado anteriormente, se pretende indagar en los aportes particulares de estas prácticas desde lo que se estudia aquí como gráfica expandida, entendida como un campo de problemas. Es decir que, más allá de una serie de procedimientos técnicos y repertorios formales, se propone aquí una mirada particular sobre los modos de operar con las imágenes caracterizados fundamentalmente por una condición procesual, serial y múltiple. A su vez, se incorpora una perspectiva de análisis donde se vinculan práctica estética y práctica política para pensar en los modos de politicidad de la gráfica, más allá de un repertorio de temas, considerando sus modos de intervención en lo público, tanto en la irrupción en el reparto de lo que puede ser visto y enunciado como en la habilitación de espacios de encuentro colectivo y activación performativa.
Entre fantasmas y promesas

Esta investigación analiza los sentidos sobre el trabajo de un grupo de jóvenes nacidxs y/o criadxs en el barrio Nueva York de Berisso (Provincia de Buenos Aires, Argentina). Este barrio es uno de los más antiguos de Berisso y es reconocido por su pasado ligado a la cultura del trabajo y por su presente vinculado a la instalación de la Nueva Terminal de Contenedores (NTC) TecPlata. Además, ha sido objeto de múltiples investigaciones que apuntaron a caracterizar su “cultura del trabajo” en la época de auge laboral de la mano de los emprendimientos saladeros y, posteriormente, de los frigoríficos. En esta Tesis nos preguntaremos cómo lxs jóvenes construyen en la actualidad sus sentidos sobre el trabajo en el contexto de un territorio atravesado por la desocupación y la precariedad laboral pero también por un discurso sobre el futuro del trabajo que, a partir de la instalación de la NTC TecPlata, aparece como prometedor para ese grupo. La comprensión del modo en que lxs jóvenes configuran sus sentidos se realizó a partir de reconstruir las memorias colectivas del barrio y de mirar sus narrativas. En este sentido, además de realizar numerosas entrevistas y conversaciones con lxs jóvenes, también analizamos sus producciones comunicacionales, participaciones en experiencias de organización sociocomunitaria, experiencias vividas y experiencias transmitidas en relación con lo laboral. La aproximación al tema-problema fue desde una perspectiva de investigación situada y comprometida con lxs sujetxs de la investigación y sus vidas. En esta Tesis sugerimos que los sentidos sobre el trabajo de jóvenes, configurados en territorios con una fuerte impronta de la “cultura del trabajo” consolidada en contextos de inmigración, se comprenden teniendo en cuenta las condiciones de producción. El análisis de dichas condiciones no sólo nos permiten comprender los sentidos sino también identificar las posibles transformaciones y cuestionamientos a los sentidos transmitidos. En particular, en las experiencias de organización sociocomunitaria es donde se habilitan y construyen instancias de discusión de los sentidos instituidos que habilitan la configuración de nuevos sentidos y la ampliación de horizontes en las trayectorias laborales de lxs jóvenes.
JUSTIFICATION OF A NEW MODEL OF MUNICIPAL DISTRICT MANAGEMENT IN THE CONTEXT OF TERRITORIAL PLANNING
Authors: Alekseeva N.A.
Published: February 2024

Since 2003, the administrative-territorial division in Russia existed as part of rural and urban settlements, municipal districts, urban districts, intracity territories. This system of territorial division showed its ineffectiveness in terms of the timeliness of solving local problems and the quality of territorial planning, since local authorities constantly experienced personnel "hunger," lack of funding. In addition, external and internal migration of the population contributed to the change in population density in certain territories, to the demand for existing objects of social, engineering and transport infrastructure. Since 2019, municipal districts have been introduced, which, according to the criterion of population density and with the consent of citizens, unite rural settlements. Accordingly, changes are predicted in the compilation of territorial planning documents - master plans for rural settlements. The main problems of drawing up and applying master plans for the development of territories were considered, the economic effectiveness of creating municipal districts in the context of territorial planning was justified on the example of one of the districts of the Udmurt Republic. Centralization of management will save budget funds, establish information collection and optimize territorial planning processes, update and create new master plans for the development of territories, and increase the investment attractiveness of territories.

The resistance change of magnetic tunnel junctions (MTJs) is used to store digital information in spin-transfer-torque magnetoresistive random-access memory. In some MTJs, intermediate (IM) states occur between two stable resistance states just after the application of a switching pulse. In this study, the effect of IM states on switching is investigated. IM states increase the switching voltage, and their probability is significantly high at a narrow pulse width. For no-error switching, MTJs with IM states require higher voltages and wider pulse widths compared with MTJs without IM states. A 300 nm MTJ has multiple IM states, whereas a 120 nm MTJ has only one IM state. Overall, a large MTJ’s free layer has multiple regions with different switching characteristics, and switching occurs stepwise through IM states.
