Maritime, and even river and lake navigation, continues to be the most widely used means of world trade. And the ports are the necessary interfaces between the forelands and the hinterlands of the different connected regions. Although this is an age-old activity, in the second half of the nineteenth century it took an exponential boost in what was called the "first globalization". The information became a crucial input for all those involved in the import and export trade, and the press of each port city began to record it day by day in singular detail. This paper is a methodological essay over a short period of time with one of these sources. To do this, we implemented computer tools for data collection and prepared a table with a series of indicators that could be analyzed with this type of source. This similarity is very marked throughout the press of the world. Although we can't offer diachronic results with this cut, its execution does allow us to build the themes and problems, the containers of information, and some instruments that we intend to use in the larger project in which our research is inserted.

Authors: Alhazmi Anwar S , Shqaidef Abedalrahman , Mohamed Elsayed Mohamed Abdelaziz , Alam Mohammad Khursheed
Published: February 2025

Background A crucial component impacting the efficacy of orthodontic therapy is the frictional resistance between orthodontic archwires and brackets. Archwires with surface coatings may greatly decrease this resistance, allowing for better tooth movement with fewer side effects. In this simulated clinical investigation, the frictional resistance of orthodontic archwires and brackets with various surface coatings is investigated. Materials and Methods A total of 90 orthodontic brackets and archwires were categorized into three groups (n=30 per group) based on the surface coatings of the archwires: Group A (uncoated stainless steel), Group B (Teflon-coated stainless steel), and Group C (nano-diamondcoated stainless steel). Testing was conducted using a universal testing machine with a simulated dry environment. Frictional resistance was measured by applying a 500 g load, and the readings were recorded in Newtons (N). Results The mean frictional resistance values observed were: Group A (5.4 ± N), Group B (4.2 ± 0.5 N), and Group C (3.1 ± 0.4 N). Nano-diamond-coated archwires (Group C) exhibited significantly lower frictional resistance compared to Tefloncoated (Group B) and uncoated archwires (Group A) (p < 0.05). Conclusion Surface coatings, particularly nano-diamond coatings, significantly reduce the frictional resistance between orthodontic archwires and brackets. This finding suggests that nano-diamond-coated archwires may improve the efficiency of orthodontic treatment by reducing frictional forces. Further clinical studies are warranted to confirm these results.

La educación patrimonial centrada en los vínculos como educación en valores
Authors: Fontal Merillas Olaia
Published: February 2025

El cambio que ha experimentado el concepto del patrimonio en las últimas dos décadas ha permitido resituar el acento en las relaciones entre las personas y los bienes –los vínculos–. La educación es la disciplina que se ocupa de generar estos vínculos, de forma que las personas pasen de considerar que no tienen ningún tipo de relación con los bienes patrimoniales a ser conscientes de los potenciales valores que estos tienen y proyectarlos sobre ellos. Por eso, la educación patrimonial puede ser entendida como una educación en valores que da respuesta al cumplimiento de los Derechos Culturales en el acceso, la participación y la contribución al legado cultural, garantizando la igualdad y la no discriminación, respetando el derecho a identificarse con comunidades, protegiendo las prácticas culturales dentro del marco de los derechos humanos, eliminando barreras para el acceso cultural y promoviendo la participación de minorías y comunidades en la formulación de políticas.

El IAPH y la US investigan cómo proteger como espacios patrimoniales y urbanos los jardines históricos de Andalucía
Authors: De Tomás Medina Carmen , Castellano Bravo Beatriz , Torres García Miguel
Published: February 2025

El Instituto Andaluz del Patrimonio Histórico y la Universidad de Sevilla han colaborado en el desarrollo de una investigación que propone la creación de un catálogo de protección específico para los jardines históricos de Andalucía. La novedad que aporta la propuesta radica en el entendimiento de estos, como zonas verdes imprescindibles de la ordenación urbana y como espacios con un incuestionable valor patrimonial.
Esta consideración provoca que los aspectos a proteger que recoja el catálogo propuesto se determinen a partir de la importancia que tienen los jardines históricos para ambas perspectivas, independientemente de que las competencias en cuanto a ordenación, protección y gestión de las mismas pertenezca a distintas Administraciones de la Comunidad Autónoma. Además, hace que el documento del catálogo se proponga como Instrumento complementario de la Ordenación Urbanística. Lo que implicaría que su tramitación y entrada en vigor se llevasen a cabo de forma conjunta con los Planes de Ordenación Urbana definidos en la Ley 7/2021, de Impulso para la Sostenibilidad del Territorio de Andalucía, consiguiendo que la identificación y protección de los jardines históricos de Andalucía sea efectiva en el mismo momento en el que se apruebe dicho instrumento de planeamiento.
El trabajo se ha desarrollado en el marco de una estancia de investigación realizada por la profesora de urbanismo Carmen de Tomás Medina, en el Departamento de Proyectos del Instituto Andaluz de Patrimonio Histórico.

Published: February 2025

This study aims to test the effectiveness of sawdust as an alternative fuel to replace coal in a 50 MW power plant in an effort to reduce dependence on fossil fuels and have a negative impact on the environment. The use of coal in power plants produces high carbon emissions that contribute to climate change. Sawdust, as a by-product of the wood industry, is considered an environmentally friendly fuel because of its abundant availability and its calorific value close to coal. This study was conducted by measuring the calorific value, fuel consumption, and electrical energy output produced during power generation using sawdust compared to coal. The measurement results show that the calorific value of sawdust is 3900 kcal/kg, slightly higher than coal, which has 3878 kcal/kg. Although the fuel consumption of sawdust is almost equivalent to coal, the energy output produced by sawdust (47,090 kWh) is lower than coal (50,900 kWh). The thermal efficiency of sawdust is recorded at around 25.72%, slightly lower than coal, which has an efficiency of 27.76%. Despite its lower efficiency, these results suggest that sawdust can still be a viable alternative fuel, especially if emission reduction and desirability are priorities. This study shows that sawdust has the potential to be a more environmentally friendly energy source and support efforts to transition energy towards a more sustainable system.

The waste problem is one of the serious problems faced by every city in Indonesia, including Bengkulu City. To overcome the problem of waste production which continues to increase every day, the government's role is needed in efforts to transport waste with various facilities and support from the surrounding community. One effort to solve the problem of waste piling up in Temporary Disposal Sites (TPS) is to schedule effective transportation to Final Disposal Sites (TPA). To do the scheduling, one possible approach is a mathematical approach. The purpose of this research is to build a Vehicle Routing Problem (VRP) model using Ant Colony Optimization (ACO), and determine the solution of this model to determine the optimal solution to the problem of transporting waste from all TPS to TPA. This research involved 29 TPS in Bengkulu City. This model is solved using Python 2.7 programming language and PuLP modeller and CPLEX Solver. With 2000 iterations, solutions were found in a relatively short time, which is less than 10 minutes. There are 6 garbage transportation routes in Bengkulu City which are considered as a VRP problem by using ACO which can transport garbage and considering the capacity of garbage trucks. From this route, a total distance of 128 km is obtained.

Studying and mastering the English language is highly important in the current era of globalization. Considering that the influence of globalization has expanded into various fields such as technology, economy, politics, trade, and more. Technology plays a crucial role in understanding and keeping up with changes in the era of globalization. It helps us acquire information, communicate, enhance productivity, expand opportunities, and adapt to changes. The advancement of information technology has entered various aspects of life, including the field of education. Smartphones are one of the widely favored information technology devices, and Android, as the most widely used smartphone operating system, holds a global market share of 70.48%. There are various learning applications on the Google Play Store, but these apps tend to have monotonous and less interactive content, leading users to quickly feel bored. To address these challenges, this research proposes a solution through the implementation of gamification in English language learning applications. Gamification is a concept aimed at enhancing motivation and learner engagement. The researcher uses the Octalysis Framework as a method or framework for designing effective gamification. The researcher selects Madrasah Tsanawiyah Pembangunan UIN Jakarta as the testing ground for the created application. The User Acceptance Testing (UAT) results reach a score of 83.7, interpreted as 'Very Good.' Post-application usage evaluation also indicates an 18% increase in student motivation. These results show that the M-Learning English application with a gamification approach using the Octalysis Framework can facilitate the learning process, meet the needs of teachers at Madrasah Pembangunan UIN Jakarta, and enhance student motivation and interest in learning.
MIKHAIL TCHÉKHOV – DO DIÁLOGO COM A ANTROPOSOFIA A UMA TEATRALIDADE DO INTANGÍVEL
Authors: Dias Natacha
Published: February 2025

O presente  artigo analisa o modo como o ator, diretor e pedagogo teatral russo Mikhail Tchekhov (1891-1955) desenvolveu sua abordagem teatral da imaginação a partir de um diálogo com a Antroposofia, ciência espiritual fundada por Rudolf Steiner no início do século. Conhecido com o mais brilhante discípulo de Konstantin Stanislávski, Mikhail Tchekhov foi obrigado a se auto exilar, em 1928, ao se descobrir investigado por associações com essa importante corrente esotérica, proibida na Rússia a partir de 1923. Pelo mesmo motivo, sua obra seria censurada em seu país natal até o final dos anos oitenta. O artigo demonstra o modo como a perspectiva antimaterialista e não determinista da Antroposofia comporá, em Tchekhov, uma pedagogia capaz de explorar objetivamente os fenômenos suprassensíveis da cena. Por fim, transpondo a reflexão sobre a formação e do treinamento teatral, busca-se demonstrar que tal legado antecipa aspectos de uma teatralidade performativa e transcendente, conforme noções utilizadas por Fischer-Lichte e J. Féral, a compor uma visão do teatro como fenômeno que dá a ver o intangível.
O O CORPO HIEROFÂNICO: O TEATRO DA CRUELDADE DE ANTONIN ARTAUD ENQUANTO TRANSFORMAÇÃO FÍSICO-ESPIRITUAL DAS CORPOREIDADES
Authors: Rodas Ramalho Daniel
Published: February 2025

O presente estudo tem como objetivo discutir as possíveis interações entre Arte, corpo e transformação físico-espiritual no Teatro da Crueldade de Antonin Artaud, refletindo acerca das propostas teatrais artaudianas enquanto caminho para a transformação espiritual das corporeidades. A princípio, situamos brevemente o surgimento do Teatro da Crueldade artaudiano no contexto da França do século XX, discutindo a crítica explícita de Artaud ao teatro “textocêntrico” da época. A seguir, interpretamos a concepção de crueldade no teatro artaudiano, refletindo acerca de seus possíveis sentidos e relações com as “corporeidades”. Por fim, relacionando às considerações de Nietzsche (2007), Villagómez (2020), Barbara (2017) e Eliade (2018), analisamos as proposições de Artaud em suas obras ensaísticas O teatro e seu duplo (2006) e Linguagem e vida (2008), evidenciando a relação que as mesmas estabelecem com uma concepção “dionisíaca” de Arte – a partir de Nietzsche –, através da comunhão entre o teatral, o “espiritual” e o ritualístico, numa verdadeira hierofania dos corpos.
