Aprendizaje basado en proyectos en educación infantil: Una metodología emergente
Authors: Martínez Enríquez Paula 
Published: October 2023

El Método de Proyectos, también denominado Aprendizaje Basado en Proyectos (ABP en adelante), se basa en la creación, indagación y construcción colaborativa en el que un grupo de alumnas y alumnos diseñan, planifican y resuelven entre todos, construyendo su propio aprendizaje de forma significativa y contextualizada. El Aprendizaje Basado en Proyectos (ABP) es una metodología educativa que tiene sus raíces en las corrientes pedagógicas del constructivismo y el enfoque de aprendizaje centrado en el alumno/a (Handrianto & Rahman, 2019). Aunque el ABP ha sido aplicado en diferentes niveles educativos, este artículo estudia su aplicación en la etapa de Educación Infantil. Por lo tanto, en el presente texto se detalla el desarrollo de esta metodología tan relevante en la etapa de Educación Infantil, en la que el alumnado experimenta, busca información, fomenta su creatividad e investiga las diferentes cuestiones que surgen de los desafíos y los problemas planteados.
En definitiva, este artículo profundiza en el origen, conceptualización, rol del docente y Sistema Educativo del ABP en Educación Infantil, una metodología educativa que, lejos de ser novedosa, fue impulsada en el siglo XIX por William H. Kilpatrick (1871-1965) con el fin de consolidar la necesaria práctica del ABP en las aulas de Infantil como método indispensable y consumado.
A Code of Laws, Which Did Not Exist: How Began to Teach the Siete Partidas in the Universities
Authors: Marey Alexander 
Published: October 2023

The author analyzes the history of the Siete Partidas of Alfonso X the Wise to establish when they began to be taught at universities and why the Partidas became the subject of lawyers’study in so late. He emphasizes that the Partidas were perceived by Castilian lawyers and notaries precisely as local law, as opposed to ius commune, represented by the texts of the Justinian Corpus and the norms of canon law. The author sees the reason for this in the language in which the Partidas was composed — the romance language never became a «language for the high culture», which means that the texts created in it had practically no chance of becoming scholastic authorities. At the end of the article, the author shows that at universities began to study the Partidas only in the midst of 18th century, after the creation of the departments of the so-called «derecho patrio». Up to this point, the legal community had kept the texts of royal law out of the university classrooms, although the most intelligent and astute of jurists recognized the need to study it.
Lex Regia in the Writings of Oldrado da Ponte: Pros and Cons for the Emperor
Authors: Ponomareva Maria 
Published: October 2023

The article examines the argument elaborated by Oldrado da Ponte, an Italian postglossator, in one of his legal consultations known as Consilium 69. This piece of Oldrado’s writings is a refutation of the possibility of world monarchy de iure, which means the impossibility of one world laic power, the emperor’s power. In the corpus of Roman law which was studied and commented on by medieval jurists the emperor’s power was substantiated by lex regia, mentioned in the Digests, and according to them the emperor owes his power to the Roman people, who had transferred it into him. Among the glossators this fact was commented in different ways, but the emerging of the ius commune system of legal knowledge allowed Oldrado to create a universal hierarchy of different species of law as a genre. This hierarchy assumes and demonstrates that different species of law have different amount of authority, therefore the emperor’s power as instituted by ius civile can not pretend on the world scale, because ius civile is less authoritative then ius gentium which prescribes the existence of many kingdoms. Consequently, Oldrado refutes de iure the world monarchy and asserts the plurality of laic powers
Dissection as a Method of Modern European Anatomy: Devoted to the 480th Anniversary of “De Humani Corporis Fabrica Libri Septem” by Andreas Vesalius

Published: October 2023

The article is devoted to the 480th anniversary of the publication of Andreas Vesalius’s “De humani corporis fabrica libri septem” and considers its biographical, historical, cultural contexts. The authors compare the results of Andreas Vesalius' investigation to other anatomical studies in the late Middle Ages and the Renaissance, presenting Vesalius’s work as the creation of a new European scientific approach in anatomy, identical to a research experiment in physics. It is demonstrated the significance of the dissection method in the form proposed by Andreas Vesalius for modern anatomy and medicine. The principal work of Andreas Vesalius is considered as the most important source of anatomical vocabulary, which is the prototype of international anatomical nomenclature. The biographical and historical issues presented by the authors allow modern readers to reveal the meanings of Andreus Vesalius’s paper, the original meaning of which was lost with all the time that has passed. The results of modern studies investigating the work of the great Flemish anatomist, little known to the Russian reader, are presented.
Climate change and maritime law: A review of IMO governance mechanism
Authors: Zulfiqar Khadija , Chang Yen-Chiang 
Published: October 2023

<p><strong><em> </em></strong>International maritime trade has long played a pivotal role in human development; however, its environmental impact cannot be disregarded. Air pollution (that includes Carbon and Sulphur emissions—all together Greenhouse Gases) emanating from ships has emerged as a significant contributor to climate change, prompting growing concern among the international community. The combustion of fossil fuels in ship engines releases pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter into the atmosphere, adversely affecting both human health and the climate. In recognition of the need to tackle this issue, international laws have been established to regulate ship emissions. This research paper analysed the IMO’s regulations under international law for mitigating climate change, with a particular focus on various global initiatives controlling sulphur, carbon and GHG emissions. It is suggested that cooperation between public and private interests as well as at regional levels will play a crucial role in combating climate change and promoting global shipping sustainability.</p>
RAÇA E CLASSE NA CONFIGURAÇÃO DA PROSTITUIÇÃO

Published: October 2023

Este artigo buscou interpretar o relato biográfico de Catarina, mulher negra, nortista e amazônida, em situação de prostituição de rua, no município de Nova Olinda-TO. Buscando suporte em uma análise interseccional (DAVIS, 2016) e a partir da história de vida de Catarina, investigamos o destaque que adquiriu o corpo feminino por meio da maternidade, sexualidade e raça, observando como isso se transformou em um instrumento de subalternização da mulher, inclusive por meio da prostituição. Como resultado desta investigação, observamos que os padrões racistas, classistas e de gênero foram mobilizados pelas estruturas de opressão como instrumentos para a exclusão de Catarina, representativa de inúmeras mulheres, principalmente por meio da estigmatização racista e de gênero, o que definiu a prostituição como lugar social dessa mulher negra.
La traducción clásica "como investigación". Evocaciones de un "hombre de letras de su época". A 100 años de su natalicio. Entrevista a Bulmaro Reyes Coria - Centro de Estudios Clásicos
Authors:   Universidad Nacional Autónoma de México, Reyes Coria Bulmaro ,   Instituto de Investigaciones Filológicas,   Centro de Estudios Clásicos
Published: October 2023

Bulmaro Reyes Coria platica sobre su ingreso en 1978 al Instituto de Investigaciones Filológicas y sobre la creación del Centro de Estudios Clásicos en 1966 —entonces llamado Centro de Traductores de Lenguas Clásicas—, uno de cuyos propósitos fue combatir un "desdén oficial” que existía por la traducción, en este caso, por traducción grecolatina. Ello se consolidó con la creación del Instituto de Investigaciones Filológicas a expensas de Rubén Bonifaz Nuño, en 1973. La traducción, “en sí misma, sola ella —nos dice— es una investigación, ya que no hay manera probada de traducir un texto sin estudiarlo”.

FRESHWATER STROMATOLITES FROM AN EARLY PERMIAN WETLAND (MANEBACH, THURINGIAN-FOREST BASIN, GERMANY): STRUCTURE, DEVELOPMENT, AND PALEOENVIRONMENTAL CONTEXT
Authors: HELLWIG ALEXANDRA , TRÜMPER STEFFEN , RÖßLER RONNY , KRINGS MICHAEL 
Published: October 2023

Abstract
Fossil stromatolites enclosing structurally preserved land plant remains have rarely been documented and studied in detail. Permineralized woody Tylodendron sp. conifer axes (slender stems, branches) from a lacustrine sedimentary sequence in the lower Permian fossil Lagerstätte of Manebach (Thuringian-Forest Basin, central Germany) are frequently surrounded by stromatolites that consist of successive, usually asymmetrical microbial layers. The stromatolites show various growth forms ranging from laminar to palisadic. They developed in stagnant water from microbial overgrowth dominated by slender, unbranched sessile cyanobacterial filaments aligned vertically into tufts or turf-like stands. Interspersed among the filaments were other filamentous and coccoid microorganisms. Preservation of the Tylodendron axes can be exquisite and sometimes even includes extraxylary tissues containing remains of fungi, suggesting that stromatolite formation began soon after the axes had entered the water and were perhaps even conducive to their preservation. Structurally similar fossil microbialitic structures from elsewhere likewise demonstrate that they were effective in preserving plant morphology. The Manebach stromatolites and the plant remains they contain contribute to a more accurate understanding of the complex biological processes in late Paleozoic lake ecosystems.
Mitigating Gas Migration Using Foamed Cement on Shallow Thermal Wells in Northeast Alberta
Authors: Sylvestre C. , Oliveira J. , Jiao H. 
Published: October 2023

Abstract
A foamed cement solution was designed and implemented to cement shallow intermediate casing strings in a heavy oil play in Northeast Alberta after conventional area-specific cementing solutions could not prevent surface casing vent flows. Analysis of the challenging well parameters that led to flowing gas identified why conventional solutions were not able to solve the issues. Foamed cement was pursued as a better technical solution and ultimately led to its successful placement in the field. The two primary challenges for cementing these wells was first ensuring full cement annular coverage around the pipe in a large hole that was deviated at 45° right from surface, and secondly to prevent gas flow through optimization of slurry compressibility, gel strength and viscosity as very little hydrostatic pressure and low well temperatures were present. The process of introducing foamed cement involved lab testing to obtain desired cement properties, computer simulations to verify expected pressures and calculate nitrogen concentrations for each section of the wellbore, and finally operational procedures to ensure jobs were completed successfully. Analysis of the conventional job design methodology and the results in the field that continually led to well failures will be described. The advantages of foam cementing will be reviewed leading to the new project design consisting of lab testing and simulation outputs. Next, the foam job design procedure was created to ensure rates and pressures would be sufficient to place the cement effectively while not inducing losses due to the higher viscosity of foamed cement and relatively low fracture gradient. Several cement jobs were analyzed for key success metrics during the pumping phase, including observations and challenges with areas for future improvement. Results of conventional cemented wells will be compared to those cemented with foamed cement looking at economics, operational complexity and ultimately well integrity. Several key conclusions are made to suggest foam cementing solutions should become a standard practice in the area and not remain a last resort. This project introduced foam cementing to very shallow thermal wells which have not typically been treated with foamed cement. Significant technical & operational hurdles were overcome to confirm proper well control and ensure the energized cement could be pumped safely and effectively. The resulting key learnings and suggested best practices will be shared.
Novel E-Line Method Restores Well Barrier by Re-Establishing Communication with Control Lines
Authors: Faraoun A. , Knappskog Ø. , Benguergoura M. 
Published: October 2023

Abstract
An offshore producer well located in the North Sea was designed to include control lines connected to a communication nipple enabling the installation of a wireline retrievable subsurface safety valve (WRSSSV) in case the downhole safety valve (DHSV) failed. However, the DHSV had become stuck in an open position, and attempts to open the communication port had been unsuccessful. This caused the well to be lacking a critical barrier and meant a potentially costly workover re-completion was required.
An alternative solution in the form of an e-line conveyed surface-controlled cutting tool was proposed as a means to establish communication with the control line. The cutting tool was applied at the termination point of the control line. The tool’s expandable machining arms were deliberately limited in their range to a pre-determined extent to prevent damage occurring to the completion, cutting with precision to the minimum required to establish communication. If communication was established, it would be possible to install and operate the WRSSSV via the control line through the newly created hydraulic channel.
A test at the onshore facility was performed and proved the concept. During testing, the pressurized control line was monitored for a drop in pressure as an indication of a successful incision, meaning that once communication was established the WRSSSV could be installed and operated via the control line through the newly created hydraulic channel. In the subsequent well operation, a drop in control line pressure occurred after nine minutes of cutting, indicating a communication breakthrough. A WRSSSV was installed, tested, and operated successfully using the control line. The well barrier was hence restored, and the well was put back in production.
This novel e-line solution not only prevented the need for a costly workover re-completion operation, but also provided a safer and more cost-effective operation, with a reduced C02 footprint. It was a successful first-time application; the well was secured, and production was restored.
How Downhole Conditions Impact Acidizing Performance in Carbonate Reservoirs?
Authors: Sayed M. A. , Chang F. C. 
Published: October 2023

Abstract
Carbonate reservoirs consist mainly of calcite or dolomite or a mixture of both minerals. Hydrochloric acid (HCl) is frequently injected to stimulate the productivity of such formations. At temperatures above 200°F the reaction rate between HCl and carbonate becomes so fast that the treatment can result in shallow penetration and face dissolution. The HCl-carbonate reaction kinetics is complicated by the released carbon dioxide (CO2) phase behavior.
Typical experiments on carbonate acidizing use 1,000 psi system back pressure as a mean to control the release of CO2 and keep it in the solution. The CO2 can be partially in the gaseous phase, which creates forced convection and therefore increase in apparent reaction rate. Acidizing treatments are usually performed at higher pressures, and temperatures, to push the acid to either create wormhole or etched fracture surfaces. The overestimated reaction rate due to the unrealistic experimental parameters can lead to underestimation of acid penetration and over-design of acid volume and injection rate requirements. The insight of pressure effect on acid-carbonate reaction rate has been published before. This paper is aimed at studying the combined effect of downhole condition of pressure and temperature on the acid and rock reaction rates and the overall performance (mainly wormhole propagation and structure) of the acid solution in more depth.
Core flooding experiments are performed to cover a wider range of parameters of permeability, injection rate, and more importantly pressures and downhole temperatures to simulate more realistic reservoir conditions. Core samples were scanned using a micro-CT scanner to evaluate the wormhole propagation inside the core sample. In addition, the kinetics of CO2 phase transition, the solubility of CO2 in water are also investigated as functions of pressure and temperature to help better explain the core flooding results.
It is found that the CO2 solubility in water at 300°F increases 4 times when pressure increases from 1500 psi to 8,000 psi. At 250°F and under similar conditions of injection rate and acid concentration, increasing the system pressure from 1,500 to 7,000 psi caused a 50% reduction in the acid volume needed to achieve breakthrough indicating an improvement in the acid penetration rate into the rock. At injection rate of 5 ml/min and under a pressure of 5,000 psi, 15 wt.% HCl breaks through core even at temperature as high as 350°F without causing any face dissolution. At high pressure, the HCl acid penetrates deeper than the preconceived notion because it is naturally more retarded than previously believed due to its full supercritical phase and higher CO2 solubility. It is very critical that the reaction rate measurements are performed under realistic downhole conditions to better simulate and design the acidizing treatment.
