Neon Afterwords
Authors: Montezemolo Fiamma
Published: December 2024

Neon Afterwords (2016) es una instalación inmersiva en la que siete frases, escritas en tubos de luz LED fluorescentes, flotan en diferentes alturas en el espacio oscuro de una sala. Las frases seleccionadas por la artista provienen de «El Etnógrafo», el cuento de Jorge Luis Borges escrito en 1969.
El espectador, rodeado por las palabras luminosas que se exhiben en el espacio oscuro sin una jerarquía de lectura sugerida, puede captar su interacción y superposición al seguir una capa de significado centrada en la percepción y la experiencia. El contenido de las frases evoca el «secreto» descubierto por el antropólogo en su experiencia de trabajo de campo y su negativa, a su regreso, a explicarlo.
Neon Afterwords incluye la mencionada obra de neón y tres ejemplares del libro de Borges Elogio de la sombra en su versión bilingüe (español/inglés). En él se incluye el cuento «El Etnógrafo». Distribuido el relato en seis páginas y presentado en los tres libros expuestos, las frases clave que se reproducen en neón se borran de los libros con cinta azul, haciendo una clara referencia al artista italiano Emilio Isgrò.

¿No hay nada oculto bajo el sol? El financiamiento de terceros en arbitraje y las obligaciones de revelación bajo el ordenamiento jurídico del Ecuador
Authors: Larrea Savinovich Andrés , Alarcón Peralta Juan Martín
Published: December 2024

El financiamiento de terceros (FPT) o también conocido como Third Party Funding es una figura que ha ganado un espacio importante en el arbitraje internacional en la última década. Esencialmente, el FPT implica que un tercero, ajeno al proceso, decide financiar a una de las partes, en todo o en parte, los costos y gastos relacionados con el arbitraje a cambio de un beneficio económico. Si bien el FPT no es un mecanismo nuevo en Estados Unidos o Europa para garantizar el acceso a la justicia, en América Latina ha aumentado su popularidad en los últimos años y, cada vez más, resulta común encontrarse con arbitrajes en los que participa un financista. En el Ecuador, esta figura aún resulta extraña y novedosa para muchos. Además, la Ley de Arbitraje y Mediación no hace referencia a los financistas en arbitraje ni a las obligaciones de las partes que reciben financiamiento de terceros. Sin embargo, con el incremento de arbitrajes en los que una de las partes cuenta con el respaldo de un financista vale preguntarse: ¿Tienen las partes la obligación de revelar su situación frente a los árbitros? ¿Existe alguna obligación legal de revelación bajo el ordenamiento jurídico ecuatoriano? Este artículo explora la figura del financiamiento de terceros en arbitraje y las obligaciones de revelación bajo las leyes domésticas.
Los casos Burlington y Perenco: Una mirada a las discrepancias ambientales en aspectos de determinación de responsabilidades y cuantificación de daños
Authors: Limongi Izaguirre Emilia , Sánchez Icaza César
Published: December 2024

Las reconvenciones de Ecuador ante el Centro Internacional de Arreglo de Diferencias Relativas a Inversiones (CIADI) por daños ambientales en el territorio ecuatoriano, trajeron como resultado situaciones atípicas para la práctica arbitral: (i) planteamiento de dos reclamaciones paralelas por los mismos daños ambientales producidos en una misma zona geográfica; (ii) pretensión expresa de la reclamante de que escogería la decisión más favorable a sus intereses; (iii) aplicación de reglas distintas para establecer responsabilidades civiles; (iv) contraria valoración de los mismos informes periciales por parte de los Tribunales; (v) expedición de un laudo posterior que “complementó” el laudo anterior, en lo que respecta a la cuantificación de daños; (vi) necesidad de un amplio conocimiento técnico de los peritos y árbitros para resolver sobre daños ambientales derivados de actividades petroleras en zonas de difícil acceso; etc. Estas situaciones hacen necesario el análisis de las consideraciones de ambos Tribunales que justificaron sus decisiones.

El silencio administrativo en el arbitraje nacional ecuatoriano ¿novedad o paradoja en el artículo 5 del Reglamento a la Ley de Arbitraje y Mediación?
Authors: Almeida Vintimilla Gabriel Eduardo
Published: December 2024

Una paradoja es un hecho o proposición aparentemente contrarios a la lógica; por su parte, una novedad, consiste en un cambio reciente producido sobre un objeto específico de forma abstracta o concreta. Ambos sustantivos se caracterizan por expresar atención e interés respecto a un tema en particular. En este caso, el artículo 5 del reciente Reglamento a la Ley de Arbitraje y Mediación, al regular los supuestos jurídicos para la suscripción, celebración y ejecución de convenios arbitrales con instituciones públicas con posterioridad a la controversia, causa sin duda un gran interés y atención en la esfera arbitral; principalmente, porque la configuración de dicha figura jurídica guarda elementos esenciales propios de la institución del silencio administrativo. Como se sabe, el silencio administrativo tiene sus propias características y matices, por lo que incluso le es inherente un procedimiento específico para su ejecución, sin embargo, cuando entra en comparación con el artículo del Reglamento referido, surgen al menos tres hipótesis resultantes de un análisis nacional y comparado, en el que se plasma las posibles consecuencias y situaciones que pueden llegar a tener cabida al momento de iniciar un arbitraje entre un contratista privado y una entidad pública contratante. El presente trabajo demostrará que, en función de las situaciones y supuestos que se presenten en cada caso, el artículo 5 del Reglamento a la Ley de Arbitraje y Mediación producirá una gran paradoja jurídica, o en su defecto, una interesante novedad excepcional en el sistema jurídico ecuatoriano demostrando a su vez, las implicaciones y situaciones que podrían presentarse en cada caso.

Authors: Guerrero del Pozo Juan Francisco , Yépez Idrovo María Victoria
Published: December 2024

En la sentencia No. 1573-15-EP/21, como medida de reparación integral dentro de una acción extraordinaria de protección, la Corte Constitucional dejó parcialmente sin efecto un laudo arbitral, al verificar que se vulneró la garantía de motivación en una de las secciones de dicha decisión jurisdiccional. Sobre la base de esta sentencia, el presente artículo analiza el alcance de la reparación integral en acciones extraordinarias de protección sobre arbitraje en las que se declare la vulneración del derecho al debido proceso en la garantía de motivación. Para ello, se examina la jurisprudencia de la Corte Constitucional relativa a las acciones extraordinarias de protección derivadas de procesos arbitrales y, posteriormente, se realiza un análisis crítico de la medida de reparación dictada en la sentencia No. 1573-15-EP/21, a la luz del principio dispositivo, de la naturaleza de las decisiones jurisdiccionales y de la garantía de motivación.

Construyendo un estándar aplicable: La prueba para mejor resolver bajo el artículo 23 de la Ley de Arbitraje y Mediación
Authors: Toscano Andrade David , Ortega Abad Gabriela , Rodas Merino Adriana
Published: December 2024

La prueba para mejor resolver contenida en el artículo 23 de la Ley de Arbitraje y Mediación (“LAM”) no es una norma que faculta a las partes a solicitar prueba adicional de manera libre e indiscriminada. Se trata de una potestad discrecional del tribunal arbitral y, si bien esta puede operar a petición de parte, su aplicación es excepcional y, por ende, restrictiva. Como consecuencia del carácter excepcional, la solicitud de prueba para mejor resolver debe cumplir con requisitos específicos, sin los cuales esta no puede operar. Por lo tanto, resulta indispensable la construcción de un estándar para la correcta aplicación de esta norma.

Published: December 2024

The paper analyses and compares possible predictive models for predicting pipeline defects using machine learning. As an example of the models, the data from in-tube diagnostics for stress corrosion cracking are selected. Special attention was paid to the description of the learning process of models based on machine learning algorithms based on retrospective data. Extended metrics are presented for the prepared parameters of the defects themselves and related data from the survey reports. The performance metrics of the algorithms are given in comparison to the probabilities of a correct prognosis. Conclusions have been drawn on the correlation of defects of this type with data on the soil composition of the soil of the segment of the analysed pipe. The analysis of statistical data on the defects by the pipe orientation was carried out. An approach has been proposed and tested to improve the accuracy characteristics of the model based on the Random Forest algorithm using preliminary data selection, which made it possible to achieve a heuristic probability of more than 80%.

Authors: Miranda do Nascimento Natalia , Barana Ana Cláudia
Published: December 2024

O vinagre, uma solução aquosa contendo ácido acético e outros compostos, apresenta desafios na análise sensorial devido à sua intensidade de sabor. Sua qualidade é influenciada pela matéria-prima e processos de fermentação. Este trabalho tem o objetivo de realizar uma revisão sistemática e integrativa, da avaliação sensorial e destacar a importância dessa abordagem na caracterização dos vinagres ao longo dos anos. Uma revisão bibliográfica de 27 anos foi conduzida, abrangendo diversas bases de dados. Os estudos empregam metodologias variadas, como Flash Profile, Análise Descritiva, escalas hedônicas de 9 pontos e análises detalhadas de compostos voláteis usando técnicas como cromatografia gasosa-olfatométrica. Os trabalhos envolveram um número limitado de provadores, refletindo a dificuldade em recrutar participantes. Essa característica pode comprometer a formação de um painel sensorial robusto, afetando a qualidade e a precisão das avaliações. A pesquisa destacou a complexidade sensorial dos vinagres, influenciada pela matéria-prima e pelos processos de produção. A análise por gênero revelou diferenças na expressão emocional, destacando a importância de se ter provadores divididos igualmente por gênero. Conclui-se que é fundamental avançar na definição de protocolos que garantam a segurança e a confiabilidade da análise sensorial de vinagres, contribuindo para um melhor entendimento e valorização desse produto complexo.
Adaptation of PCR technique for quantitative estimation of genetic material from different regions of chromosome 21 in cases of trisomy 21.
Authors: Nowacka Joanna , Helszer Zofia , Walter Zofia , Płucienniczak Andrzej , Kazewski Bogdan
Published: December 2024

Pre- and postnatal diagnosis of chromosomal aberrations is generally based on conventional cytogenetic analysis. In this paper, we have devised a quantitative polymerase chain reaction (Q-PCR) method to determine gene dose effects and applied it in cases of regular trisomy 21 as a model. The method is based on quantitative assessment of PCR products after using primers amplifying DNA fragments located in the pericentromeric, heterochromatic, euchromatic and telomeric regions of chromosome 21. A gene dose effect on the amount of PCR product in cases of trisomy 21 was confirmed. Moreover, a correlation between the amount of the PCR product of the examined sequences and their location in the chromosome was observed. The obtained results suggest that the Q-PCR technique can be applied in the diagnosis of aneuploidies.

Characterization of free radical-induced cell injury processes of placenta cells is of vital importance for clinical medicine for the maintenance of intrauterine fetal life. The present study has analyzed cell injury processes in cells of the choriocarcinoma cell line JAR treated with menadione, an anticancer drug, and H(2)O(2) in comparison to osteosarcoma 143B cells using electron microscopic and flow cytometric techniques. Flow cytometry on JAR cells exposed to 100 muM menadione and double-stained with Annexin V and propidium iodide (PI) detected apoptotic cells reaching the maximum after 4 h of incubation with a rapid decrease thereafter. Viable cells became decreased to 46% of the control after 2 h of incubation, reaching 5% after 4 h. Cells stainable with both Annexin V and PI began to increase distinctly after 2 h of incubation, reaching 55% after 4 h. Electron microscopy showed that cells stainable with both dyes specified above had condensed nuclei and swollen cytoplasm, suggesting that they were undergoing a switch of the cell death mode from apoptosis to necrosis. On the other hand, 90% of 143B cells remained intact after 4 h of menadione treatment although the intracellular levels of superoxide were always higher than those of JAR cells treated with the drug. In contrast, JAR cells were more resistant than 143B cells to H(2)O(2)-induced cytotoxicity. These results may suggest that cytotoxicity of menadione cannot be explained simply by oxygen free radicals generated from the drug. The resistance of JAR cells to oxygen free radical-induced cytotoxicity may be advantageous for intrauterine fetal life.

Published: December 2024

Ultrasound is commonly used to treat knee osteoarthritis (KOA), which has unique advantages with regard to relieving pain and inflammation as well as delaying cartilage degeneration, but the underlying mechanisms are less clear. The study aimed to investigate the therapeutic effects of ultrasound on vascular endothelial growth factor (VEGF) expression in cartilage, the synovium, and synovial fluid (SF) in a rabbit model of KOA. Twenty-four New Zealand rabbits were randomly divided into ultrasound (group A), sham ultrasound (group B) and no-ACLT control groups (group C). Six weeks after undergoing anterior cruciate ligament transection (ACLT), group A was treated with ultrasound and group B was treated with sham ultrasound. Two weeks thereafter, the morphology of the synovium and cartilage were observed. Cartilage and synovium were scored using the Mankin scale and Krenn V scores, respectively. VEGF expression in the cartilage, SF, and synovium of ACLT knee joints was analyzed via immunohistochemistry, western blotting, and RT-PCR. Cartilage degeneration and synovitis were the most severe in group B and the least severe in group C. Similarly, Mankin scores and Krenn V scores were highest in group B and lowest in group C (p<0.05). There were also significant differences in the VEGF IOD of cartilage or synovium, VEGF protein content in SF, and VEGF mRNA expression in cartilage or SF (p<0.05). Ultrasound can relieve synovitis and delay cartilage degradation, and the mechanisms of ultrasound for the treatment of KOA may involve inhibition of the expression of VEGF in the synovium, SF, and cartilage.
Estimation of Influence of Target Obliquity on Efficiency of PELE Ammunition
Authors: Catovic Alan , Razic Faruk
Published: December 2024

In the available literature, no research on target obliquity influence on terminal ballistics of PELE could be found. This study aimed to give an insight into this phenomenon. As a part of the research, numerical simulations were performed with four different target obliquity angles, namely 0°, 30°, 45°, and 60°. Before the simulations, the numerical model was validated with available experimental data. It was shown that the case of a target inclination of 30° is the most effective in stopping PELE ammunition, for the given type of materials and design, because it shows the lowest number of fragments created and also the lowest velocity of fragments, with large number of fragments lost in front of the target. Target obliquity leads to the asymmetric deformation of the projectile and at larger target obliquities a good part of the jacket and core is fragmented and lost in front of the target. Residual velocity of projectile is smaller for larger target obliquities. The deformation of the aluminum core is significant for larger target obliquities. Perforation time for larger target obliquity angles is longer. The lower side of the projectile casing is more deformed than the upper side for target obliquities larger than 0°. Fragments that originate from the front part of the projectile jacket are faster compared to fragments originating from the projectile lower sections. The perforation hole is significantly larger for higher target obliquity angles than for smaller ones. For a 60° inclination of the target, several massive fragments are created in front of the target.

Authors: Mahardika Andika , Runturambi Arthur Josias Simon , Revindo Mohamad Dian
Published: December 2024

The current development of online gaming technology can facilitate social interaction, forming a virtual society. This social interaction is continued with economic interaction, namely the consumption of online games. This research uses a multidisciplinary approach to understand consumption behavior in online games. The research takes place in Jakarta, Indonesia, and interviews three key opinion leaders in online game communities. This is qualitative research using grounded theory. The results show that microtransactions in online games are driven by the influence of structural and cultural dimensions in a virtual society, in this case, online games. In the context of virtual society, structural dimensions of pressure are found in the form of exploitation by developers and communities. However, online players resist and reconfirm these structural and cultural pressures, such as stopping consumption. So, there is duality in the social structure of virtual society. This adds new perspectives to existing research more concerned with monetization strategy.

Authors: López-Rodríguez Campo Elías , Gutiérrez Bernal Luis Gabriel , Páramo Renza Luis Alberto
Published: December 2024

This research aims to identify the main findings regarding the measures used to establish brand awareness from the perspective of consumer behavior. To achieve this, a quantitative bibliometric study was conducted on articles published in Scopus, using the Bibliometrix software, and a qualitative systematic review was performed following the PRISMA protocol parameters. The findings indicate that the main metrics, unaided awareness, aided awareness, perceived value, trust, and word of mouth in particular, in virtual scenarios, virtual interactivity, quality of information and market opinions stand out. These measures are fundamental tools for strengthening brand awareness management in companies. Research on brand awareness has relied on similar constructs for decades, without significant conceptual or methodological innovations. Therefore, it is necessary to revitalize brand awareness management by incorporating perspectives adapted to the digital environment, where new constructs related to brand awareness in virtual contexts emerge, such as digital interaction and the influence of user opinions—key elements for the development of corporate brand equity.

Published: December 2024

Entrepreneurship is born from the initiative of a person to establish their business idea in a legal field to generate impact in the social and economic field. Likewise, the person's perceived level of education is a variable that can also influence the intention to start a business, an indicator of growth in the rate of entrepreneurship. The present research aims to identify what factors and attitudes graduates in higher education from Guayaquil-Ecuador have regarding the entrepreneurial approach. Being a type of exploratory and descriptive research, where the business values and intentions (VIE) questionnaire was applied as an instrument, which incorporates the factors of the theory of planned action and Schwartz's theory of personal values, to a sample of 439 professionals to correlate the dimensions that affect entrepreneurial intention, such as entrepreneurial attitude, subjective norm, entrepreneurial self-efficacy, and values; and for its estimation, structural equations were used to validate the variables of the proposed research model and the incidence of the factors on entrepreneurial intention.

Published: December 2024

The purpose of this research is to determine 1) the development of Augmented Reality Atlas Volcano Series media (ARAVS) that is suitable for use; 2) increasing student learning outcomes from the cognitive aspect; and 3) find out students' responses to interest after using the ARAVS media. This research and development (R&D) process refers to design model of Dick and Carey. The trial of the developed product was carried out at Model Terpadu Bojonegoro State High School with a field trial sample of 120 class X students. Data were analyzed using descriptive statistics, paired sample t-test, and discriminant test. The results of the product development validation test from social studies learning developer experts and learning media experts are in the very feasible category. The results of small group trials are in the feasible category, and field trials are in the very feasible category. The results of the t-test on cognitive aspects showed that there was an increase in student learning outcomes on volcanism in social studies subjects after using AR media. Students have a positive interest in using the ARAVS because the media (ARAVS) is considered concrete, innovative, and interactive. Media (ARAVS) is not boring and is not difficult to adapt to social studies learning. In general, the formative evaluation shows that the product resulting from this development is very suitable for use as an alternative to virtual and digital-based media in social studies learning on Volcanism material.

Authors: Mehridiz Hassan , Ghasemi Mohamad Sadegh , Saeedi Hassan , Varmazyar Mahsa , Garosi Ehsan
Published: December 2024

Introduction: Lifting loads in awkward postures is a main cause of low back musculoskeletal disorders. In this context, researchers have used various indicators to determine the relationship between biomechanical variables and the risk of these disorders. This study aimed to investigate the correlation between plantar pressure distribution and the values of UTAH back-compressive forces (BCF) and lifting index (LI) during symmetrical load-lifting tasks.
Material and Methods: Thirteen healthy men, aged 25 to 35, took part in this study. The participants were instructed to symmetrically lift loads weighing 7.5 kg and 15 kg in 15 different postures, considering three horizontal distances (A, B, C) and five different heights (1-5). Pressure on the foot soles was recorded using 16 force-sensitive resistors (FSR) corresponding to eight anatomical areas on each foot. The BCF and LI were also calculated using the UTAH method and the NIOSH equation, respectively. Statistical analysis was performed using SPSS (version 21) software.
Results: Based on the results, when the load was closest to the body (A1-A5), the highest pressure was recorded in the heel and the 4th and 5th metatarsal of both feet. In lifting a load of 15 kg in the A2, B1, B2, C1, C2 postures and lifting a load of 7.5 kg in the C2 posture, the average BCF exceeded 700 pounds. The LI was greater than 1 for specific postures (B1, B2, B4, B5, C1-C5) at 15 kg and (C1, C2, C4, C5) at 7.5 kg load-lifting. During the 7.5 kg and 15 kg load-lifting, there was a significant correlation between the plantar pressure and the values of LI and UTAH (p-values < 0.05) in most postures.
Conclusion: The results showed a significant correlation between plantar pressure distribution and load- lifting postures. The study findings, which identify risk levels associated with lifting postures, lay the groundwork for future research aimed at categorizing safe and unsafe plantar pressure patterns
Application of Three-Dimensional Risk Matrix Approach for Occupational Injury Risk assessment in an Automotive Factory
Authors: Mohammadiyan Mahdi , Ahmadi Omran , Yaseri Mehdi , Karimi Ali
Published: December 2024

Introduction: Risk assessment matrix is a tool used in a project’s risk assessment process to identify the probability of risks and evaluate the potential damages caused by those risks. Generally, a risk assessment matrix is drawn in a two-dimensional form, with two factors: the severity of the accident and the probability of its occurrence. So, the purpose of this study is to develop a specific risk assessment matrix in a three- dimensional form by using the accident severity grade (ASG) rating system, the accident probability, and taking into account the preventive approach that helps occupational injury risk assessment in the automobile industry.
Material and Methods: This cross-sectional study was conducted in 1402 (2023) in one of the automobile assembly industries. One hundred cases were randomly selected by examining the reports of this industry’s past accidents. The ASG scoring checklist was designed and completed by the experts to assess the severity of accidents. Then, considering the ASG score, the frequency of the accident, and its preventability, a three-dimensional risk assessment matrix specific to this industry was presented.
Results: According to the findings of the accident analysis, a total of 658 accidents and 15,019 lost working days were recorded in this period. The most influential factor in the occurrence of accidents is related to “surface condition” (influence factor = 0.6), and the least of them belongs to the “weather conditions” (influence factor = 0.028). The results of the three-dimensional matrix show that when the ability to prevent accidents increases, the risk of accidents decreases.
Conclusion: Using the accident severity grade (ASG) and preventability in the proposed three-dimensional risk assessment matrix, the accident severity can be quantified immediately after the accident. This approach allows monitoring workplaces during the accident, leading to timely control and risk management implementation.

Published: December 2024

Introduction: One of the questions that always arises in the minds of researchers, especially young researchers, is what pattern the progress of science follows in their field of expertise and what is the direction of the studies. The purpose of this study is to analyze the content of the studies published from 2011 to 2022 in Persian scientific journals in the field of workplace safety and determine the direction and scientific process of studies in this field
Material and Methods: All the studies published from the years 2011 to 2022 in the Persian scientific research journals ”Iran Occupational Health”, “Occupational Health and Safety”, “Occupational Health Engineering”, ”Iranian Journal of Ergonomics”, “Occupational Medicine” and “Occupational Health and Health Promotion” were gathered using census method from the websites of the journals. In total, 595 published articles were categorized according to the thematic codes determined by the opinion of experts, the theme of “risk analysis, assessment, and risk management” had the highest percentage of frequency (18.66 percent), while the theme of “safety application in other industries or specific workplaces” had the lowest frequency of percentage (0.34 percent). Approximately 50 percent of the variance of the published studies explained the themes of “risk analysis, risk assessment, and management”, “inspection, analysis and modeling of accidents”, “human error and safety”, “social, organizational factors, culture, safety climate, and behavior-based safety”.
Conclusion: The existing trends emphasize the importance of learning lessons from accidents as a reactive approach and risk management, human factors, and behavioral aspects in safety interventions as a preventive approach. The research development of the country’s safety at the workplace should be further improved with new policies in different fields while taking advantage of international scientific advances on the specific functions and challenges of the country and with a problem-oriented approach.
Multipolarity, Alliances and Internal Balancing: Opportunities for Brazil

Published: December 2024

El objetivo de este artículo es obtener una visión sobre el papel de Brasil en un esce­nario multipolar desequilibrado. Para lograr este objetivo, se presentan los principales conceptos y supuestos del neorrealismo y el neorrealismo ofensivo. Se argumenta que la estrategia óptima para Brasil en este momento es perseguir un balance interno para mejorar su posición de negociación entre las grandes potencias y competidores similares. En este sentido, el artículo es normativo, aunque sus recomendaciones se derivan de los imperativos del sistema, como las vulnerabilidades de las alianzas en un mundo multipolar. Estados Unidos está involucrado en áreas clave en Asia y Europa, lo que crea un margen de maniobrabilidad en América Latina, históricamente una zona de influencia para Estados Unidos. Además, Brasil debe fortalecer su poder material, ya que es un país de considerable riqueza y tamaño, y, por lo tanto, de inte­rés para las grandes potencias. Para lograr una posición de negociación sólida, deben abordarse problemas estructurales como el gasto en defensa y la inversión. Concluimos que, independientemente de si Brasil “elige un lado” o mantiene una posición neutral, el balance interno es necesario para alcanzar sus objetivos.

Najbardziej ekologicznym paliwem kopalnym jest gaz ziemny, który charakteryzuje się niską emisją CO2 i brakiem zanieczyszczeń pyłami podczas jego spalania. Obecnie w Polsce eksploatowanych jest siedem podziemnych magazynów gazu, które stanowią część systemu gazowniczego. Pięć z nich zostało utworzonych w sczerpanych złożach gazu ziemnego, a dwa w kawernach solnych. Do podstawowych zadań podziemnych magazynów gazu należą m.in. zaspokajanie skokowego zapotrzebowania na gaz w sezonie zimowym, możliwość optymalizacji systemu gazowniczego oraz pełnienie roli rezerw strategicznych. Jednakże przeprowadzone ostatnio analizy wykazały, poprzez porównanie pojemności czynnej krajowych magazynów ze średnią z krajów unijnych, że obecne pojemności podziemnych magazynów gazu w Polsce nie są wystarczające i powinny zostać rozbudowane do 7,56 mld m3. W artykule został przedstawiony projekt koncepcji rozbudowy pojemności czynnej wirtualnego podziemnego magazynu gazu, który pozwoli na jej powiększenie do 130% aktualnej pojemności czynnej. W pracy wykonano cyfrowy model symulacyjny 3D za pomocą programu JewelSuite 6.2 firmy Baker Hughes wraz z modelem rozkładu przestrzennego facji oraz modelami parametrycznymi, takimi jak model rozkładu przestrzennego współczynnika porowatości i przepuszczalności geofizycznej, oporności elektrycznej oraz współczynnika porowatości neutronowej, co pozwoliło na wybór optymalnego miejsca na odwiercenie nowych otworów eksploatacyjnych, niezbędnych do zatłoczenia i odebrania nowej pojemności czynnej. W koncepcji określono wielkość pojemności czynnej możliwej do uzyskania, zakładając górne ciśnienie pracy instalacji nieprzekraczające 8,32 MPa, oraz podano podstawowe parametry magazynu po jego rozbudowie do 130% aktualnej pojemności czynnej. W artykule zaproponowano wykonanie pięciu nowych odwiertów horyzontalnych.

The utilisation and processing of crude oil sludge is one of the major global challenges. Therefore, it is necessary to justify the following scientific solutions in the field of oil sludge utilisation and processing worldwide: the study of the physicochemical properties of oil sludge in order to obtain construction grade bitumen; detection of dispersion of solid particles in the composition of oil sludge; development of the optimal technological parameters for the process of obtaining construction grade bitumen from oil sludge; establishing a correlation dependence between process efficiency and the environment, the content of light fractions in the sludge composition, the process temperature. In this work, oil sludge was diluted with a solvent in a ratio of 70:30, with light naphtha used as a solvent. A laboratory distillation column was used to separate the sludge into fractions, and the chemical composition of the oil sludge was investigated. Oil sludge consists of asphaltenes up to 4.2–4.5%, resins up to 21.0%; paraffin-naphthenic hydrocarbons up to 41.2%; monocyclic aromatic hydrocarbons up to 4.6%; bi- and tricyclic aromatic hydrocarbons up to 5.8%; polycyclic aromatic hydrocarbons up to 9.7%. The paper also presents the results of the change in the viscosity and density of the distillate fractions separated during the distillation of diluted oil sludge. Density and viscosity were measured using an areometer and a VPZh-4, respectively. One of the main components of the oil sludge is water. A series of experiments were conducted to determine the water content using the Dean and Stark method. In addition, the sulphur content in oil sludge diluted with solvents – light and heavy naphtha, heavy gas oil – was determined.
Interpretação Analítico-Comportamental para o Transtorno de Ansiedade Social e Proposta de Critérios Funcionais para Diagnóstico
Authors: Iêgo Sandro , Ribeiro Maria Júlia Ferreira Xavier
Published: December 2024

O Transtorno de Ansiedade Social (TAS) é descrito pelo Manual Diagnóstico e Estatístico dos Transtornos Mentais (DSM-5) como uma condição clínica na qual o indivíduo teme, sente-se ansioso e/ou evita ser avaliado em interações sociais. Uma compreensão analítico-comportamental do TAS deve identificar e descrever padrões de comportamento e contingências comportamentais que caracterizam o que determinada comunidade verbal nomeia como TAS. Este trabalho tem como objetivos apresentar um modelo analítico-comportamental de interpretação do que o DSM denomina como TAS, bem como propor um modelo para identificação e avaliação do comportamento socialmente ansioso baseado em critérios funcionais. Para isso, o TAS foi operacionalizado funcionalmente usando os critérios diagnósticos especificados pelo DSM. A operacionalização consistiu em retratar o TAS usando contingências comportamentais, mediante a identificação dos comportamentos socialmente ansiosos, seus antecedentes contextuais e suas consequências. Como resultado, foram identificadas cinco contingências comportamentais que caracterizam o TAS, que basearam a elaboração de critérios funcionais para identificação e avaliação do comportamento socialmente ansioso. Em conclusão, este trabalho demonstra que é possível retratar por meio de contingências comportamentais os fenômenos comportamentais caracterizados comotranstornos mentais em manuais diagnósticos, como no exemplo do TAS.
Science and Human Behavior como sistema de psicologia: Compreendendo o livro por sua estrutura
Authors: Laurenti Carolina , Lopes Carlos Eduardo
Published: December 2024

Publicado em 1953, Science and Human Behavior (S&HB) foi inicialmente escritopor B. F. Skinner com o propósito de auxiliá-lo em suas aulas para alunos de graduação emHarvard. À época, resenhas do livro consideraram a obra uma “nova psicologia”, e um retratobem-acabado do sistema científico de Skinner. Neste ano, S&HB completa 70 anos, o quepode sugerir que o livro é datado. O objetivo deste artigo é defender que a leitura de S&HBainda pode ser proveitosa, mesmo para analistas do comportamento. Para sustentar essa tese,discutiremos a necessidade de uma leitura integral da obra, respeitando sua estrutura sistêmicae recursiva. Por meio dessa estratégia, pretendemos dar relevo a algumas característicasda proposta skinneriana que tendem a ser negligenciadas tanto no ensino quanto na pesquisaem Análise do Comportamento.
MÁ CONSCIÊNCIA: dívida, culpa e crueldade internalizada em a Genealogia da Moral
Authors: Costa José Carlos Rocha
Published: December 2024

O presente artigo analisa o conceito de má consciência a partir da perspectiva de Nietzsche, destacando a conexão entre a consciência moral e a culpa. O filósofo argumenta que a consciência moral é fruto da interiorização de instintos agressivos, que, reprimidos pelas normas sociais, possibilita o surgimento da má consciência. Essa dinâmica se origina da relação credor-devedor em sociedades primitivas, onde o não cumprimento de promessas resultava em punições. Com a ascensão do cristianismo, a culpa se tornou um conceito central, associando a natureza humana ao pecado original, desta forma, a moralidade é vista como obediência a costumes ancestrais, onde a crueldade, inicialmente exteriorizada, é reorientada de volta e se internaliza.
UCRANIZAÇÃO, POLONIZAÇÃO E RUSSIFICAÇÃO: entre a colonização e a guerra da Rússia na Ucrânia
Authors: Cavalcante Junior Claudio
Published: December 2024

Este texto aborda noções como “ucranização”, “russificação” e “polonização” que ao longo da história da Ucrânia tomaram a forma de políticas públicas e tiveram impacto sobre populações ucranianos em situação de dominação sob diferentes impérios. Com a atual guerra russo-ucraniana, a questão dos direitos culturais de determinados grupos étnicos ou nacionais, assim como a necessidade de reforçar a identidade nacional ganha importância no contexto de combate a um genocídio.
NEGRI LEITOR DE FOUCAULT: aportes para se pensar o poder constituinte
Authors: Freitas Lorena Martoni de
Published: December 2024

Este trabalho explora a influência do pensamento de Michel Foucault nos trabalhos de Antonio Negri em torno do tema do poder constituinte. Em "O poder constituinte" (1992), Negri resgata a noção de poder constituinte na prática revolucionária, criticando sua abordagem jurídica e destacando sua natureza extraordinária e ilimitada. Nele, o autor italiano sugere a necessidade de se recorrer aos trabalhos de Foucault para compreender a configuração do "sujeito-potência" que demarca o conceito de poder constituinte. Essa hipótese é então retomada em "assembly" (2017), obra coescrita com Michael Hardt, na esteira de um trabalho voltado a repensar a dinâmica revolucionária no marco dos novos movimentos sociais por eles denominados “multitudinários”. Nesse processo, conclui-se que o filósofo italiano faz uma instrumentalização criativa de Foucault, desconsiderando algumas das premissas fundamentais do filósofo francês expostas em suas reflexões acerca do poder.

Authors: Lu Jiaoyun , He1 Shubin , Wang Zhennan , Yang* Huimin
Published: December 2024

This study aimed to test the hypothesis that stoichiometric ratios of C, N and P change with plant growth during flowering. The C:N, C:P and N:P varied without solid trends during flowering. The C:N was significantly different only between cuts, while the C:P and N:P were influenced by age, cut and their interaction. The C:N and C:P were higher in the 1st cut than in the 2nd cut, while for N:P, it was opposite. No solid trends were observed with the effects of age on both C:P and N:P. The N and P were closely correlated with C:N, C:P and N:P. Conclusively, stoichiometric ratios of C, N and P varied during flowering and changed with stand age and cut.

Authors: Rathod* Pandit S. , Patil D.H. , Dodamani B.M.
Published: December 2024

A field investigation was carried out during winter seasons of 2012-13, 2013-14 and 2014-15 at Agricultural Research Station, Gulbarga (Karnataka) to evaluate the effect of pre and post emergence herbicides on weeds and productivity of chickpea cv. JG-11. Ten treatments were tested in randomized block design with three replications. Among the herbicidal treatments, pendimethalin 38% CS 0.75 kg a.i ha-1PE + hand weeding (HW) at 30-35 days after sowing (DAS) and pendimethalin 30% EC 0.75 kg a.i ha-1+ imazethapyr 2% 1.0 kg a.i ha-1 PE + one hoeing at 30-35 DAS recorded significantly higher seed yield (1198 kg ha-1), net returns (Rs. 25107 ha-1) and B:C ratio (2.10) and lower weed dry weight (11.3 g m-2) and higher weed control efficiency (83%) than all other herbicidal treatments except two hand weedings at 20 and 40 DAS. It may be inferred from the present investigation that these herbicidal treatments could be used effectively as an alternative for controlling weeds and obtaining optimum seed yield of chickpea under rainfed conditions of Karnataka.
