The clustered protocadherins (cPcdhs) play a critical role in the patterning of several CNS axon and dendritic arbors, through regulation of homophilic self and neighboring interactions. While not explored, primary peripheral sensory afferents that innervate the epidermis may require similar constraints to convey spatial signals with appropriate fidelity. Here, we show that members of the γ-Pcdh (Pcdhγ) family are expressed in both adult sensory neuron axons and in neighboring keratinocytes that have close interactions during skin reinnervation. Adult mice of both sexes were studied. Pcdhγ knock-down either through small interfering RNA (siRNA) transduction or AAV-Cre recombinase transfection of adult mouse primary sensory neurons from floxed Pcdhγ mice was associated with a remarkable rise in neurite outgrowth and branching. Rises in outgrowth were abrogated by Rac1 inhibition. Moreover, AAV-Cre knock-down in Pcdhγ floxed neurons generated a rise in neurite self-intersections, and a robust rise in neighbor intersections or tiling, suggesting a role in sensory axon repulsion. Interestingly, preconditioned (3-d axotomy) neurons with enhanced growth had temporary declines in Pcdhγ and lessened outgrowth from Pcdhγ siRNA.In vivo, mice with local hindpaw skin Pcdhγ knock-down by siRNA had accelerated reinnervation by new epidermal axons with greater terminal branching and reduced intra-axonal spacing. Pcdhγ knock-down also had reciprocal impacts on keratinocyte density and nuclear size. Taken together, this work provides evidence for a role of Pcdhγ in attenuating outgrowth of sensory axons and their interactions, with implications in how new reinnervating axons following injury fare amid skin keratinocytes that also express Pcdhγ.

SIGNIFICANCE STATEMENTThe molecular mechanisms and potential constraints that govern skin reinnervation and patterning by sensory axons are largely unexplored. Here, we show that γ-protocadherins (Pcdhγ) may help to dictate interaction not only among axons but also between axons and keratinocytes as the former re-enter the skin during reinnervation. Pcdhγ neuronal knock-down enhances outgrowth in peripheral sensory neurons, involving the growth cone protein Rac1 whereas skin Pcdhγ knock-down generates rises in terminal epidermal axon growth and branching during re-innervation. Manipulation of sensory axon regrowth within the epidermis offers an opportunity to influence regenerative outcomes following nerve injury.
The Struggle Is Relative: A Comparative Processing Perspective on Academic Self-Concept and Student Mental Health

Published: October 2023

Academic self-concept (ASC) is a prominent predictor of educational achievement and student mental health. Although it is widely accepted that ASC is fundamentally comparative, little is known about different comparison types driving students’ ASC construal and its impact on mental health. Therefore, we examined whether self-evaluations relative to criteria-based, social, temporal, dimensional, and counterfactual comparison standards represent independent factors that contribute to general ASC. Next, we assessed the association of general ASC and its comparison-based facets with achievement emotions and psychopathology. University students (N=348) completed an online survey of general ASC as well as subordinate comparison-based ASC facets, positive and negative achievement emotions, psychological distress, and symptoms of student burnout. We further assessed comparison frequency, student task values, and achievement levels. Factor analysis indicated that criteria-based, social, temporal, dimensional, and counterfactual standards reflect mainly distinct yet correlated comparison domains. General ASC construal was most strongly based on the criteria-based and social facets. Favourable general ASC predicted lower learning-related anxiety, psychological distress, and student burnout. Largely similar correlations emerged for all comparison-based ASC facets, whereby the criteria-based and social facets were particularly strong predictors of learning-related anxiety. Our findings support the view that ASC construal relies on comparisons with multiple standards. Criteria-based and social comparisons were particularly dominant and may be the main drivers of learning-related anxiety. Carefully designed follow-up studies with longitudinal designs and interventions are warranted.

ON THE APPLICATION BY COURTS OF THE CATEGORY “PUBLIC ORDER” IN RELATION WITH DECISIONS OF INTERNATIONAL COMMERCIAL ARBITRATION
Authors:   National University “Odesa Law Academy”, Podtserkovnyi O.P. , Belianevych O.A. ,   Vasyl’ Stus Donetsk National University
Published: October 2023

The article examines the negative tendency towards excessive interference of state courts of Ukraine in international commercial arbitration by cancelling and refusing to enforce arbitral awards on grounds that go beyond the principle of legal certainty as an element of the Rule of Law. It was concluded that the expansive interpretation of the category of public order, applied in some decisions of the Supreme Court, will prevent the normal functioning of international commercial arbitration as an alternative way of commercial disputes' resolution in Ukraine, which not only undermines the investment prospects of Ukraine's economy, but also destroys the possibility of classifying Ukraine as a legal systems of civilized countries of the world, creates ample opportunities for abuses in the process of contesting and recognizing in Ukraine decisions of international commercial arbitration. It is substantiated that a violation of public order as a basis for refusing to recognize and enforce international commercial arbitration awards in Ukraine can be qualified in the case of clear disregard for direct prohibitions established by the state regarding the protection of sovereignty, fundamental human rights and freedoms. One of the ways to solve these problems is to the establish a legal ban on the execution of an arbitral awards in favour of the occupying country and persons related with it. Types of violations of the arbitration procedure as grounds for contesting an international commercial arbitration award or refusing to enforce it are comprehensively regulated in the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (New York, 1958), and cannot be based on expansive interpretation by the court of the arbitration procedure from the point of view of compliance with the norms established by the Civil Procedure Code and the Economic Procedure Code of Ukraine.

Published: October 2023

The article highlights the current issues of formation and use of information to ensure effective management of the economic entity. The components of management information support are substantiated. The interrelationship of the information resource, management information support and management information (including result-outcome) is argued, and the order of information data formation according to the proposed structural-logical scheme is systematized. The ways and possibilities of the most optimal implementation of the process of forming information data at the economic entity level according to their types have been identified. This will allow effective and timely processing of information from the internal and external environment in accordance with information needs. It was established that the main elements of ensuring the quality of analytical information are the stages of its analysis in accordance with the task and control over the process of such assessment. The content of the stages of the analysis, its sources and main elements, as well as control over the process of formation and methods of information analysis are substantiated. It is confirmed that the accounting and analytical system of the economic entity in instability should act as the basis for the analysis, control and audit of its activity. This makes it possible to make the most effective management decisions in the short and long term. It is proposed to consider the audit as an element of control over the implementation of management decisions, which enables the improvement of the processes taking place at the economic entity and ensures better efficiency of the flow of all its processes. Attention is focused on the relevance of the introduction of information technologies for analysis and audit. Popular software products and their capabilities in management issues were analysed, the main information threats associated with the use of IT were identified. The components of information protection, which are proposed to be grouped into three groups (managerial, legal and technical protection), are identified, their content and meaning are identified. The imperfection of information protection at modern economic entities is confirmed and it is proposed to include in this system such elements as the identification of threats in the formation and transmission of information, the selection of a software product, determining the method of calculating economic indicators and their grouping, forming a rational sequence in the process of organizing and processing information. This will make it possible to outline the boundaries of information security and control the confidentiality of information use.

The following documents collect information regarding the calibration and intercalibration of various sensors that were deployed during the North Atlantic field component of the NASA EXPORTS project (EXPORTS NA), which took place between May 4 and June 1, 2021 (Johnson et al., 2023). The EXPORTS NA campaign was designed to to provide a contrasting end member to the earlier North Pacific field campaign, and focused on carbon export associated with the North Atlantic spring bloom in which gravitational sinking of organic particles, the physical advection and mixing, and active transport by vertically migrating zooplankton are all expected to provide significant flux pathways. During EXPORTS NA data sets were collected from a variety of shipbased, autonomously-piloted, and Lagrangian platforms. Intercalibration activities were tasked to different groups within the EXPORTS project team. Team leads and contact information are listed below. The overarching goal of these activities was to identify a trusted sensor, carry out a careful calibration of this sensor, then base any intercalibraiton needs off of this sensor, occasionally propagating information across platforms. Full details of the intercalibration approach, assumptions, and summary are provided in the attached documents. All calibration and intercalibration activities were completed before data set were uplaoded to the NASA SeaBASS data repository. Data related to this cruise can be publicly accessed at: https://seabass.gsfc.nasa.gov/cruise/EXPORTSNA Updates to calibration and intercalibration documents required to reflect revised data sets will also be provided through SeaBASS.

Authors:   Institute of High–Temperature Electrochemistry UB RAS, Kalyakin Anatoly S. , Volkov Alexander N. ,   Institute of High–Temperature Electrochemistry UB RAS
Published: October 2023

A new sensor has been developed for continuous monitoring of oxygen and combustible gases content in the waste gases of thermal units. The target application of the sensor is its installation in shunt pipes of thermal units, directly into the waste gas flow. The sensor is characterized by one reference gas electrode and three measuring electrodes applied on the surface of a solid electrolyte tube made of a zirconia electrolyte (e.g., 8YSZ). The reference gas electrode and one of the measuring electrodes were made of silver, the second measuring electrode was made of platinum, the third measuring electrode was made of a mixture of zinc oxide (95 wt %) and lanthanum-strontium manganite (5 wt %). The oxygen content in the gas mixture was determined by the well-known potentiometric method in accordance with the Nernst equation, i.e. an Ag|8YSZ|Ag electrochemical cell was used. To determine the products of incomplete combustion of fuel, the method of mixed potential between Pt- and Zn-based electrodes was used; the obtained potential value was determined by the difference in the oxidation rate of carbon monoxide as the main component of unburned fuels, on different materials of measuring electrodes. The experimental results of the sensor for the determination of carbon monoxide, hydrogen, and methane in a gas mixture are presented.
The Effectiveness of Blood Flow Restriction Technique Combined with Low-Resistance Exercise in the Postoperative Rehabilitation of Patients Following Knee Surgery: A Narrative Review and Update of Evidence-Based Physiotherapy Practice
Authors: Limbari Maria , Iakovidis Paris , Kasimis Konstantinos , Lytras Dimitrios , Koutras Georgios , Fakontis Christos
Published: October 2023

Background: Blood flow restriction (BFR) therapy has emerged as a promising rehabilitation approach after knee surgery. The technique involves the use of a tourniquet or cuff to limit blood flow to the affected limb during low-resistance exercise, which creates a hypoxic environment thought to stimulate muscle growth and improve muscle function.

Objective: Our scoping review aims to examine the current literature on the effectiveness of BFR combined with low-resistance exercise on rehabilitation after knee surgery.

Method: The Google Scholar, PubMed, and PEDro databases were searched using relevant key-words. Studies that met the inclusion criteria were selected for analysis. The data from the selected studies were analyzed, categorized, and summarized to provide an overview of the findings.

Results: In total, 12 studies met the inclusion criteria and were included in the review. Outcomes such as pain, strength, and range of motion were assessed.

Conclusion: The results suggest that BFR and low-resistance exercise can be effective in improving patient outcomes following knee surgery. However, the heterogeneity of the studies made it difficult to determine the most effective approach. Further research is needed to identify the optimal dosage, frequency, and duration of BFR and low-resistance exercise for knee surgery rehabilitation.
Study on particle size and field effect with sp2/sp3 ratio of hydrogenated diamond-like carbon

Published: October 2023

Hydrogenated diamond-like carbon (HDLC) films were synthesized through a reactive gas-plasma process employing methane (CH4) and hydrogen (H2) as precursor gases on a silicon (100) wafer substrate, conducted at room temperature. The deposition process utilized a biased enhanced nucleation technique, varying the flow rate ratio of hydrogen and methane. The investigations revealed that increasing the methane flow rate led to a reduction in grain size and an augmented nucleation density of HDLC, as evidenced by contact-mode atomic force microscopy (AFM) images. This study demonstrated the effective control of diamond grain growth by introducing high-methane-concentration pulses during deposition. The field emission characteristics of HDLC samples were analyzed, revealing threshold fields of 12.2 V/μm for nanocrystalline films, 8.5 V/μm for subcrystalline films and 4.1 V/μm for microcrystalline films, corroborated by Raman spectra. Surface energy measurements indicated hydrophobic behavior in the samples. Notably, a decrease in the hydrogen/methane ratio was found to increase the sp2 character, which correlated with the emission field. AFM analysis of HDLC samples yielded surface roughness values ranging from 0.2 nm to approximately 0.01 nm, confirming the continuous, non-porous and smooth nature of the surfaces.

Published: October 2023

Este artículo de investigación representa de manera resumida los principales aspectos de la implementación y evaluación de un objeto de aprendizaje (oa) de ciencias, en estudiantes de segundo grado de primaria en la zona rural del municipio de Tuluá, Valle del Cauca, con el fin de establecer la eficacia de este material de enseñanza. Para ello, se utilizó una metodología de enfoque mixto, direccionada por el modelo de evaluación tripartito de Alzaghibi, es decir, este estudio comparó las intenciones de diseño que fundamentan el oa (características claves de diseño, ccd), las acciones del profesor y los estudiantes, y las metas de aprendizaje logradas. Los datos se recogieron a través de fuentes documentales, como: pretest y postest, observación participante, videos, relatos narrativos y reflexión de la profesora. El análisis de datos cuantitativos se realizó por medio del índice normalizado de ganancia de aprendizaje de Hake, y la información de carácter cualitativo fue interpretada con el método de análisis comparativo. Este proceso estableció relaciones de significado entre los tres elementos de la implementación y evaluación antes mencionados, las cuales fueron retratadas a través de una teoría-práctica cuya macroestrutura textual estuvo configurada por la toma de decisiones curriculares e instruccionales propuestas en el oa (ccd), las acciones del profesor y los estudiantes durante la implementación, y los aprendizajes logrados. Se concluyó que la eficacia de este oa no solo depende de la estructura teórica y metodológica que lo funda, sino también de otros aspectos como el sistema de conocimiento, creencias y valores de la profesora, el compromiso de los estudiantes con su aprendizaje, y los recursos tecnológicos con los que cuente la escuela.
Reconocimiento y validez de los derechos de los animales no humanos, y su articulación en el proceso de enseñanza/ aprendizaje de la biología
Authors: García Montes Yurieth
Published: October 2023

En el desarrollo de este artículo de reflexión, se buscó dar cuenta de los derechos de los animales no humanos, comenzando con la relación que establece el hombre con el resto de los animales. Así mismo, desde varios pronunciamientos jurídicos en todos los niveles estatales, es decir, leyes, resoluciones nacionales y decretos, se realizó una reflexión de la relevancia que los derechos de los animales no humanos tienen en el proceso de enseñanza y aprendizaje de la biología. Para esto se utilizó el método de documentación y análisis propuesto por Sabino (1966). Al finalizar la revisión, se encuentra que el reconocimiento a los animales no humanos como sujetos de derecho, en términos jurídicos, es un gran avance en el reconocimiento de la igualdad. Sin embargo, es importante seguir trabajando en la noción de protección, defensa y respeto de los animales no humanos. Así mismo, es claro que tener en cuenta los derechos de los animales no humanos en el proceso de enseñanza/aprendizaje, puede contribuir a la formación de ciudadanos autónomos, responsables, con una conciencia moral, y respetuosos consigo mismos y su entorno

Examination of the Reasoning Skills of 60-72 Months-Old Preschool Students on Socio-Scientific Issues According to Epistemic Profiles: Isparta Example
Authors: YILDIRIM Muhammed Safa , YILMAZ Şirin
Published: October 2023

The purpose of this study is to examine preschool students' reasoning about socioscientific issues (SSI) according to their epistemic profiles. A qualitative case study was used in the study. The participant group of the study consisted of 22 children aged 60-72 months studying in a public kindergarten in the central district of Isparta province in the 2021-2022 academic year. Three scenarios about SBK developed by the researchers and two different question sets related to each scenario were used as data collection tools. Before starting the main study, researcher1 spent time with the participant group as a participant-observer within the scope of naturalistic inquiry approach and the main research process was started after she was seen as a natural member of the group. During the implementation process, researcher1 met with each student in a quiet environment with one-to-one interviews and read the scenarios and aimed to reveal the students' reasoning about the scenarios. The same process was followed for each scenario. The data collection process lasted four weeks. The interviews were recorded and converted into written format. The data obtained in the study were analyzed based on content analysis and Schommer and Kuhn's epistemological belief models. According to the findings, it was concluded that the participant group could not make sufficient reasoning and had naive epistemic profiles even if they had ideas about current issues within the scope of SBK. However, as the practices progressed and the scenarios changed, positive changes were observed in students' reasoning. The findings were discussed with reference to the literature and recommendations were presented.

Precast structural walls and rafts commonly resist lateral load in structures owing to improved traits and faster construction. The behavior of five different types of precast reinforced concrete structural wall and raft connection systems is evaluated in this study. In all five configurations, the cyclic load is applied in the wall systems to observe the lateral load-carrying capacity and hysteretic characteristics. The damage and failure patterns were assessed. To confirm and contrast the behavior of the proposed precast structural wall and raft connection systems with the experimental findings, FEM analysis was used. Only shear and flexural cracks were observed. The specimen with 12 mm dia rods has the maximum load carrying capacity of 10.23 kN in the negative cycle, which is 57% more than the specimen without grouting and connector. The suggested connection can improve the resistance behavior in all key directions by absorbing more energy than precast walls under dynamic load.

In the current studies microstructure and mechanical behavior of Al7085 metal alloy with 4 and 8 wt. % of B4C composites. Liquid metallurgy method was used to create composites of Al7085 alloy with 4 and 8 weight percent of B4C particles. Microstructural analysis by SEM/EDS was performed on the prepared composites. Furthermore, ASTM E8 and E10 standards were used to examine the tensile and hardness properties of Al7475 alloy reinforced with B4C composites. The SEM analysis revealed that the particles were uniformly dispersed throughout the base alloy. EDS spectrums confirmed the reinforcement particles presence in the Al7085 alloy in the form of boron and carbon elements. Moreover, the incorporation of B4C particles into Al7085 alloy has enhanced the material's mechanical behavior. The hardness and tensile strength of Al7085 alloy was improved 27.59% and 35.91% respectively with the combination of boron carbide particles. After boron carbide particles were added to Al7085, the alloy lost some of its ductility and density. The prepared composites were then subjected to tensile fractured surfaces to investigate ductile and brittle modes of fracture.

In the present work, we investigated the effect of glucose concentration in the nutrient medium on the growth of bacterial isolates Enterococcus faecium and Enterococcus sp. from wheat bran, degraded by the action of native microbiota for various periods of time, and lactic acid biosynthesis. The cultures were identified by sequencing the 16S rRNA gene. Cultivation was carried out in a shaker incubator for 50 hours. The kinetics of bacterial growth was evaluated by measuring the optical density of the culture fluid at a wavelength of 600 nm; the lactic acid content was determined by photometric method using iron (III) chloride. Glucose and yeast extract, as well as beet molasses, were used as components of the culture medium for cultivation. It is shown that the maximum optical density characterizing the accumulation of biomass and the lactic acid content for both strains were achieved with a minimum concentration of glucose in the nutrient medium (50 g/l). These observations indicate a low resistance of the studied bacteria to elevated concentrations of glucose in the medium. Glucose concentrations of 100 g/l and above inhibited biomass growth and lactic acid synthesis. The revealed effect allowed us to make an assumption about the belonging of bacterial isolates to oligocarbophiles. When culturing a bacterial culture of E. sp., the highest yield (11.65 g/l) of lactic acid was achieved in comparison with E. faecium. It has been shown that when the glucose content in the culture medium is 50 g/l, the conversion rate of the substrate to lactate reaches 23.3%. When culturing the studied bacterial isolates on a medium containing beet molasses as a carbon source, the lactate yield was 23 g/l for the E. faecium strain and 22 g/l for E. sp. (the degree of carbohydrate conversion to MK is 46% and 44%, respectively). The high content of simple carbohydrates in molasses contributes to an increase in the productivity of biomass for the biosynthesis of lactic acid.

Published: October 2023

The article presents current data on the etiopathogenesis and risk factors of breast cancer (BC). The search for the sources was carried out in the PubMed, Medline, Cochrane Library, eLIBRARY, NHGRI-EBI Catalog of GWAS systems, publications from January 2000 to December 2022 were included. The interaction of definite risk factors, endocrine stimuli and genetic disorders causes activation / inactivation of various signaling pathways that directly or indirectly affect carcinogenesis. According to modern genetic evaluations, the contribution of the hereditary component to the formation of BC reaches 40 %. Interactiones between various risk factors form several molecular subtypes of breast carcinomas, differing in receptor status and clinical course, as well as therapeutic approaches. The details of the interaction of etiopathogenetic factors of BC are not clear, and often have a multidirectional character. Matrix metalloproteinases (MMPs) regulate the mechanisms of proliferation and apoptosis, invasion and metastasis, formation of the tumor microenvironment, neoangiogenesis, as well as intergenic signaling interactions, being an important link in the pathogenesis of BC.

Published: October 2023

Green information systems (green IS) have evolved and expanded over the years, now having a broad scope in organizations. Green IS in these organizations function to help to address climate change challenges. The growing complexity of green IS in organizations needs a conceptual framework that can articulate its different impacts at various levels while taking into consideration a holistic and integrated perspective. This research focuses on how to enhance and ensure green IS-driven green performance in organizations from an operant resources hierarchy perspective. A conceptual model is proposed to examine the role of management support for green initiatives and the role of information assurance in addressing IS misuse and process automation in relationship to green IS capability and green performance. The current study tests the effects of management support as composite operant resources and information assurance as interconnected operant resources for green IS capability in enhancing and ensuring organizations’ green performance using a matched dataset of 73 organizations. We illustrate the application of the proposed conceptual model in two real-world scenarios. This study contributes theoretically by illustrating the application of the operant resources hierarchy perspective in green IS research and provides practical action suggestions for organizations adopting sustainable practices to achieve Sustainable Development Goal (SDG) 13.

Published: October 2023

Bu çalışmanın amacı, psikolojik sermaye ile kurumsal itibar algısı arasındaki ilişki ve bu ilişkide presenteeismin aracı rolünü araştırmaktır. Çalışmanın yöntemini iki yada daha fazla değişkenin betimlendiği ve derinlemesine analiz edildiği ilişkisel tarama yöntemi oluşturmaktadır. Bu amaçla, psikolojik sermaye, kurumsal itibar ve presenteeism arasındaki ilişkiler Yapısal Eşitlik aracılığı ile oluşturulan model çerçevesinde test edilmiştir. Çalışmanın evreni, Konya Organize Sanayi Bölgesi’nde faaliyet gösteren işletmelerde çalışanlardan oluşmaktadır. Literatürde bu üç değişkenin bir arada incelendiği bir çalışmaya rastlanılmamıştır. Çalışmada veri toplama aracı olarak anket kullanılmıştır. Araştırma sonuçları; psikolojik sermayenin kurumsal itibar üzerinde pozitif ve presenteeism üzerinde negatif yönde bir etkiye sahip olduğunu; presenteeismin kurumsal itibar üzerinde negatif yönde etkiye sahip olduğunu ve yapısal eşitlik analizi sonrasında presenteeismin psikolojik sermaye ile kurumsal itibar arasında kısmi aracılık rolü üstlendiğini göstermiştir. Bu sonuçlar, hipotezlerin desteklendiğini göstermektedir. Bu çalışma, literatüre yeni bir perspektif kazandırması açısından önem taşımakta olup bir özgünlük sunmaktadır.

Authors: Leite Alana de Moraes , Schurster Karl
Published: October 2023

Este artigo tem por objetivo central a produção de uma sequência didática, no âmbito da formação de professores, que discuta a Shoah como fenômeno de crise da alteridade e suas condições de permanência no tempo presente, a partir de um diálogo entre a filosofia de filosofia de Emmanuel Lévinas e a relação entre educação, memória e escrita de Emmanuel Taub. Utilizamos o documento “Estas são minhas últimas palavras... cartas póstumas do Holocausto”, material que reúne 117 cartas, organizado pela Escola Internacional para Estudos do Holocausto do Yad Vashem – Museu Israelense, adotamos a análise categórica temática para dividir as cartas em categorias e construir “núcleos de sentido”, temas-eixo. Nossa proposta didática está fundamenta na filosofia educativa do Yad Vashem, especialmente no tocante ao uso de testemunhos no processo de ensino, nesse caso as cartas póstumas, como forma de gerar identificação entre o sujeito que estuda e o evento estudado.
RELÍQUIAS E RELICÁRIOS NA IDADE MÉDIA: ARTE E HISTÓRIA
Authors: Tatsch Flavia Galli , Nascimento Renata Cristina de Sousa
Published: October 2023

A origem complexa do culto às relíquias se estabelece na prática da veneração aos restos mortais dos mártires da fé, de homens e mulheres elevados à santidade. Este prestígio sagrado era conferido a indivíduos e objetos considerados singulares. É também um fenômeno de massas, que confere aos fiéis vestígios palpáveis e concretos. Por sua popularidade os vestígios sagrados foram manipulados e mobilizados pelos diversos poderes. Desde os primeiros cultos aos locais sagrados e às relíquias dos santos, do Cristo e da Virgem, os relicários foram elaborados e percebidos como recipientes extremamente valiosos, cuja riqueza exterior deveria incorporar e transmitir o valor espiritual dos fragmentos em seu interior.
JUSTIÇA, TRABALHO E DIREITOS: A REVISTA DO TRIBUNAL SUPERIOR DO TRABALHO E O PROCESSO CONSTITUINTE (1986-1988)
Authors: Da Silva Avelino Pedro Nunes Bento
Published: October 2023

O presente artigo busca discutir dimensões sociais de conflito na constituição de leis e direitos trabalhistas, a partir da problematização da Revista do Tribunal Superior do Trabalho, periódico produzido pela Justiça do Trabalho que se propõe tratar sobre temas do Direito do Trabalho. Por meio da leitura em série da documentação, investigamos perspectivas daquela instituição acerca de temáticas do Trabalho, Justiça e Direitos, mediante a análise de textos de ministros e magistrados que se posicionavam no âmbito de disputas no período histórico de processo constituinte na década de 1980, podendo ainda contribuir para reflexões sobre o papel ativo daquela Justiça na definição e transformação de leis e direitos trabalhistas, assim como suas perspectivas sobre formas próprias de luta e organização dos trabalhadores. Por fim, pretendemos contribuir para reflexões sobre a construção histórica da Justiça do Trabalho no Brasil.

The weak-form efficiency of cryptocurrencies
Authors: Karasiński Jacek
Published: October 2023

This study aimed to examine the weak-form efficiency of some of the most capitalised cryptocurrencies. The sample consisted of 24 cryptocurrencies selected out of 30 cryptocurrencies with the highest market capitalisation as of October 19, 2022. Stablecoins were not considered. The study covered the period from January 1, 2018 to August 31, 2022. The results of robust martingale difference hypothesis tests suggest that the examined cryptocurrencies were efficient most of the time. However, their efficiency turned out to be time-varying, which validates the adaptive market hypothesis. No evidence was found for the impact of the coronavirus outbreak and the Russian invasion of Ukraine on the weak-form efficiency of the examined cryptocurrencies. The differences in efficiency between the most efficient cryptocurrencies and the least efficient ones were noticeable, but not large. The results also allowed to observe some slight differences in efficiency between the cryptocurrencies with the largest market cap and cryptocurrencies with the lowest market cap. However, the differences between the two groups were too small to draw any far-reaching conclusions about a positive relationship between the market cap and efficiency. The obtained results also did not allow us to detect any trends in efficiency.

This work deals with the optimal design of a stand-alone photovoltaic system (SAPS) based on the battery storage system and assesses its technical performance by using PVsyst simulation. In fact, this study is carried out to determine the optimal orientation and tilt angle of a solar panel for collecting maximum solar radiation. Borj Cedria is taken as a case study site to perform the optimum tilt angle through PVsyst. PV-GIS is utilized to estimate global solar irradiance. The proposed system can produce 1314 kWh of energy for the load, which is considered technically suitable for this area thanks to a performance ratio of 58.3% and high specific efficiency generation, besides the solar fraction of about 92.5%. From an economic point of view, the SAPS can save more than 44,000 Dt per year by purchasing energy from the grid system, while considering the aspect of sustainability, 66.24 kg of CO2 annually can be avoided by utilizing the sun’s energy. Furthermore, efficient solar panel use requires its characteristics to be identified under various conditions. An original experimental setup is carried out in the LPV Lab to identify PV characteristics. Experimental and simulation results performed under PSIM software are in good agreement, which shows the experimental setup’s effectiveness.
