Building a model of the impact grinding mechanism in a tumbling mill based on data visualization
Authors: Naumenko Yuriy , Deineka Kateryna
Published: July 2023

A mathematical model was built based on data visualization for the impact grinding mechanism in a tumbling mill, which is mainly implemented during coarse grinding.
The determination of impulse interaction parameters is problematic due to the difficulty of modeling and the complexity of hardware analysis of the behavior of intramill loading.
Conceptually, it was envisaged to identify the relative dynamic parameters of the impact action as components of the model, which are criteria for the similarity of the loading movement and the grinding process. Impact power was taken as an analog of grinding performance. The initial characteristic of the impact was considered to be the averaged vertical component of the speed of loading movement in the flight zone at the boundary of contact with the shear layer. The formalization of the model revealed the effect on the performance of the mass fraction of the flight zone and the reversibility of loading.
The method of numerical modeling was applied, based on experimental visualization of the behavior of granular loading in the cross section of a rotating chamber.
The influence of the rotation speed on the performance at a chamber filling degree of 0.45 and a relative particle size of a milling load of 0.0104 was estimated by experimental simulation. The maximum productivity value was found at the relative speed of rotation ψω=1–1.05. A rational condition for impact grinding at ψω=0.75–0.9 has been established.
The test proved the effectiveness of using visualization to evaluate dynamic loading interaction analogs. Verification of modeling results was implemented by comparison with the data of the technical standard. The use of similarity criteria unifies approaches to modeling different mechanisms of destruction.
The model built makes it possible to predict the rational parameters of the grinding processes by impact, crushing, and abrasion
Determining the sequence of elimination of impurity ions from the surface of historical cold iron weapons

Published: July 2023

Confirming the authenticity of historical cold weapons and determining their age is an urgent problem in practical examination. One of the promising directions for its solution is the experimental study of the process of elimination of impurity ions from iron, which occurs throughout the long history of life.
This paper describes a model that explains the sequence of elimination of impurity ions from near-surface parts of the metal. Deformation indicators of the crystal lattice of iron were calculated and sorted in order of decreasing ionic radius of the impurity chemical element. A diagram of the deformation effect of impurity chemical elements on the volume-centered crystal lattice of iron was constructed. Ions that are larger in diameter are more actively eliminated from the surface layers of the metal, while ions that are smaller are removed to a lesser extent.
With the help of the authors’ methodology, a study of the chemical composition of the surface of collection samples of iron cold weapons of the 20th, 19th, and 18th centuries was carried out. It has been established that a metal alloy made in the recent past ‒ up to 100 years ‒ is characterized by a very active release of impurity chemical elements on the surface when it is heated. Iron weapons made up to 200 years ago have a significantly lower ability to release chemical impurities because most of the latter have already been eliminated. At the same time, samples of cold weapons of this age already have microdefects in the form of cleavage cracks and caverns, so their surface contains a significant number of compounds of eliminated chemical elements that have accumulated during the long history of their use. Older cold weapons, made 300 years ago or earlier, have impurity ions that are smaller than ferric ions, particularly silicon.
The results of the research are important for the identification and authentication of historical iron cold weapons
Improving the energy characteristics of a four-quadrant converter with pulse-width modulation
Authors: Dubravin Yury , Tkachenko Viktor , Morneva Maryna
Published: July 2023

The characteristics of the input energy converter of an electric locomotive with an induction traction electric drive were studied. The efficiency of the 4QS converter has been increased and the level of current harmonic distortions in the power supply system has been reduced. The research resulted in proposals for improving the control algorithm of the input energy converter to improve the traction-energy indicators of the electric drive and reduce the emission of high-frequency harmonics into the contact network. The results were obtained on the basis of simulation modeling of the "traction transformer – 4QS-converter" system on the example of the alternating current electric locomotive DS3 (Dnipro-Simens-3).
Modeling of the operation of the 4QS-converter of the electric locomotive was performed for the case of the maximum load of the drive under a traction mode. Two versions of the input converter control algorithm were studied and compared: the basic version of the DS3 electric locomotive and the modified version proposed by us. It was found that in the case of the basic variant of the converter control algorithm, conditions are created at certain time intervals when the capacitor of the constant voltage link on the secondary winding of the traction transformer is discharged under a traction mode. The consequence of this is a decrease in the efficiency factor of the converter and a deterioration of the harmonic distortion factor of the rectified voltage. In the modified algorithm, the discharge time of the capacitor of the constant voltage link on the secondary winding of the traction transformer is significantly reduced and the efficiency of the 4QS converter is increased
Peculiarities of the effect of antiepileptic drugs on seizures in mice with corneal kindling against the background of low-dose premedication with carbamazepine and sulthiame
Authors: Boiko Yurii , Тantsura Yevhen , Boiko Irina , Tantsura Liudmyla
Published: July 2023

The aim. The aim of the study was to evaluate the effectiveness of antiepileptic drugs (AED) with a different mechanism of action against the background of prior use of low doses of carbamazepine and sultiam in the model of corneal kindling in mice.
Materials and methods. The corneal kindling model in mice was used. The convulsive model was reproduced under the parallel preliminary administration of carbamazepine and sulthiame 30 minutes before electrostimulation. The anticonvulsant activity of AED (sulthiame, levetiracetam, carbamazepine, valproate, lamotrigine and retigabine) was studied under conditions after the formation of a stable syndrome of the generalised convulsive activity.
Results and discussion. The administration of carbamazepine and sulthiame drugs modulates the activity of the cytochrome P450 enzyme system. Thus, carbamazepine in the dose of 7 and 12 mg/kg showed no significant anticonvulsant activity (the convulsive intensity – 4.42±0.25 points; 4.44±0.32 points) after its preliminary chronic administration, the same doses of carbamazepine showed a noticeable anticonvulsant effect in the control group of animals (3.52±0.26 points; 3.2±0.6 points, respectively). The anticonvulsant activity of lamotrigine changed both in the case of the preliminary chronic administration of an inducer (carbamazepine), and an inhibitor (sulthiame) of the cytochrome P450 system.
Conclusion. Changes in the pharmacological effects of AED observed against the background of chronic administration of carbamazepine and sulthiame, in our opinion, may be due to both the modulation of the cytochrome P450 system and other groups of enzymes involved in the AED metabolism
Pollution and damage to land resources of Ukraine as a sign of criminal offenses against peace, human security and international law and order in the context of russian military aggression
Authors: Shulha Andrii
Published: July 2023

The article deals with the issues related to the legal protection of land resources of Ukraine, which were significantly negatively affected during the military aggression and hostilities by the so-called rusian federation. The article identifies and analyzes the types of pollution and damage to land resources arising from military aggression and hostilities by the rusian federation as an aggressor country. Such pollution and damage to land resources is called military-technogenic pollution of land resources. It is stated, that the conduct of not only active but also passive hostilities causes irreparable damage to land resources. This is manifested in mechanical, physical, chemical, and biological contamination of the soil cover of lands of various categories. Also, for example, digging trenches, fortified areas, ammunition and personnel storage facilities, and caponiers for military equipment causes degradation of the soil cover. The consequences of these actions indicate the presence of signs of such a criminal offense as "Ecocide" – Article 441 of the Criminal Code of Ukraine.

It is concluded, that: 1) military-technogenic contamination of the soil cover causes direct soil contamination with hazardous substances of a military nature, as well as their degradation; 2) such consequences are socially dangerous for humans and the environment, given the system of interaction "soil-plant", "soil-plant-human" 3) in general, such contamination of the soil cover should be classified under Article 441 "Ecocide" of the Criminal Code of Ukraine without applying the provisions of Section VIII "Criminal Offenses Against the Environment"; 4) the establishment of the evidence base should be carried out by joint efforts of national and international law enforcement agencies; 5) compensation for the damage, caused by the pollution and damage to land resources, should be made by way of contribution and reparation from rusia as the aggressor state

Introdução: O rugby tem elevado número de lesões que necessitam de estratégias preventivas e de recuperação pós esforço. Não se tem relatos sobre como os clubes brasileiros desenvolvem suas estratégias de prevenção de lesões e recuperação pós esforço. Objetivo: Apresentar as estratégias de prevenção de lesões e recuperação pós esforço desenvolvidas pelos clubes masculinos de rugby brasileiros. Métodos: Aplicou-se questionários online, respondidos por profissionais de 125 clubes de rugby brasileiros das séries A, B e C, questionados sobre: (1) lesões no rugby, (2) estratégias para prevenção de lesão, (3) métodos de recuperação pós esforço e (4) caracterização dos profissionais. Resultados: Foram relatadas lesões articulares e/ou ligamentares (49,6%), músculo-tendíneas (43,2%), concussões (4%) e ósseas (3,2%), associadas a gestos técnicos inadequados, principalmente ao tackle. Estratégias preventivas de lesão eram realizadas por 102 clubes (81,6%), com ênfase em fortalecimento, resistência e alongamento musculares. Avaliação para estabelecer as estratégias preventivas foram relatadas por 73 (58,4%) clubes. A recuperação pós esforço foi desenvolvida por 94 (75,2%) clubes, com principalmente alongamentos e exercícios ativos de baixa intensidade. O profissional de educação física era o principal responsável em 50 (40%) clubes, seguido pela associação entre educadores físicos e fisioterapeuta em 32 (25,6%) clubes. Os clubes que não realizavam prevenção ou recuperação apontaram a falta de verba e interesse dos profissionais e dirigentes como as principais causas. Conclusão: É necessário maior empenho e organização dos clubes brasileiros de rugby para que possam desenvolver estratégias de prevenção e recuperação de lesão mais adequadas.
CONDIÇÕES SOCIOECONÔMICAS E PREVALÊNCIA DE SÍFILIS GESTACIONAL E CONGÊNITA EM PORTO ALEGRE - RIO GRANDE DO SUL
Authors: Netto Francine Oliveira , Jacociunas Laura Vicedo
Published: July 2023

Introdução: A sífilis é uma infecção sexualmente transmissível causada pelo Treponema pallidum. Neste estudo abordamos a Sífilis gestacional, quando o diagnóstico ocorre durante o pré-natal, parto ou puerpério, e congênita, quando a causa é por transmissão vertical. É considerada uma infecção importante, mesmo com métodos de prevenção e tratamento já bem estabelecidos. Desta forma, o presente estudo teve como objetivo avaliar a prevalência de sífilis gestacional e congênita em Porto Alegre e verificar se há possibilidade de estabelecer uma relação entre a condição econômica dos pacientes e prevalência desta infecção.Métodos: Estudo transversal retrospectivo utilizando as informações dos bancos de dados da Biblioteca Virtual da Atenção Primária à Saúde e do Instituto Brasileiro de Geografia e Estatística, referente ao município de Porto Alegre. Foram selecionados dados referentes a pessoas diagnosticadas com sífilis gestacional ou congênita entre 2019 e 2020 e de rendimento médio dos responsáveis por domicílio, em salários mínimos.Resultados: Houve diminuição de 13% nos casos de sífilis gestacional e aumento de 5% nos casos de congênita em 2020, em relação a 2019, bem como observou-se uma relação pouco representativa entre maior renda e menor número de casos por região. Conclusão: A sífilis continua sendo um importante problema de saúde pública, ainda que o estudo aponte redução dos casos de sífilis gestacional, houve aumento de sífilis congênita em 2020, quando comparado a 2019. A relação socioeconômica reforça que a doença não afeta somente uma população específica. Entendemos que mais estudos em períodos distintos de tempo devem ser estimulados.

Tras las huellas de la mujer de Job, la Sophía y las narrativas de lo femenino en el libro de Job (2,9-10; 28)
Authors: Piñango Rebeca Cabrera
Published: July 2023

El presente artículo quiere ser una contribución al estudio del libro de Job desde la perspectiva femenina. Este libro bíblico es desestabilizador porque cuestiona las ideas arraigadas en el imaginario judío sobre la teología de la retribución. Job se presenta como un personaje cuya fe se va purificando con el tiempo. Pasa de pedir un mediador a creer en un Dios liberador en medio de una constante actitud de queja. En este contexto, la mujer de Job contrasta con su marido. Los estudiosos la cuestionan, olvidando que ella, a excepción de la enfermedad, tuvo las mismas pérdidas que Job. ¿No le asiste ninguna razón? Hay que seguir sus huellas y buscar la sabiduría en palabra de mujer.

Development and financing of the high-tech sphere in the Eurasian Economic Union countries
Authors: Dokhoyan Zohrab
Published: July 2023

The degree of innovative development and implementation of high technologies determines the competitiveness of not only individual companies, but also the entire countries. High-tech companies, as a key element in the value chain, play an important role in the industrial transformation and restructuring of the current economic model, thus becoming a driver of structural shifts in the economy. In this regard, a well-developed state policy in the sphere of high technologies with effective financing tools acquires special relevance.
The article deals with the peculiarities of development of the high-tech sphere in the countries of the Eurasian Economic Union. A special emphasis in the research is placed on Russia as the leading country of the Union. It is revealed that in the conditions of international sanctions pressure the technological policy of Russia is focused on achieving such strategic goals as technological sovereignty, commercialization of technologies and restoration of the system of technological and production relations.
The paper analyzes government support measures for the high-tech sector and startup financing mechanisms in the countries under consideration. The study showed that the driver of high-tech activity in most countries of the Eurasian Economic Union is the sphere of information technologies. At the same time, Kyrgyzstan has the most modest results.
The article reveals the main problems hindering the development of the high-tech sphere, including unfavorable market conditions, underdeveloped institutional environment, lack of financial resources and lack of local investors. At the same time in the majority of countries of the Eurasian Economic Union there is a shortage of highly qualified specialists, however in Armenia the problem of the young specialists deficit is the most acute.
The study also identifies the main vectors of further development of the sphere of high technologies, taking into account the current geopolitical instability.

Authors: Minakov Andrey
Published: July 2023

The article presents an assessment of the state of trade, economic and investment cooperation between the Far Eastern regions of Russia and the key countries of the Asia-Pacific region: China, South Korea and Japan. The authors studied the contribution of the countries of the Asia-Pacific region to commodity exports and commodity imports of Russian regions included in the Far Eastern Federal District, which made it possible to identify the predominance of energy resources and seafood in the export of this region. The most dependent on supplies to China are the Amur Region, the Jewish Autonomous Region, the Baikal Territory, on supplies to Japan — the Kamchatka Territory, on supplies to South Korea — the Sakhalin Region. The countries of the Asia-Pacific region supply cars, machinery and equipment, various consumer goods with high added value to the Far East. After the start of the military conflict in Ukraine, Japan joined the anti-Russian sanctions, South Korea remains neutral, and China uses the opportunities that have arisen to deepen economic cooperation with the Far Eastern regions and Russia as a whole. At the beginning of 2022, $113 billion of foreign investment was accumulated in the Far Eastern Federal District, incl. $84 billion — in the Sakhalin region, where large oil and gas projects are being implemented, but offshore territories are the main investors, which does not allow us to reliably assess the contribution of China and other countries of the Asia-Pacific region to the investment activities of the Far Eastern regions. At the same time, according to the Chinese side, by the end of 2022, Chinese investments in the Far Eastern Federal District exceeded $13 billion, there are significant opportunities for further development of bilateral trade and investment cooperation between the Far Eastern regions and the People's Republic of China.
A UNIVERSIDADE E A ARTE TRANS-FORMAM (PARA) A(S) VIDA(S)
Authors: Bessa-Oliveira Marcos Antônio
Published: July 2023

De uns tempos para cá, mas não somente, a Universidade se tornou instituição malvista em lugares em que a sociedade prima por questões não voltadas a uma formação crítico-social como primeira prerrogativa. Em certas situações dessas, até mesmo a Ciência mais essencial à humanidade está sendo destituída de importância. Em relação à arte a questão não se diferencia muito porque ao limitar uma liberdade social crítica, a arte acaba por ser obstruída na sua intenção transformadora primeira. Ao certo, nas culturas ocidentais em que os propósitos em relação à Universidade, a ciência e a arte são restritos à político-partidários, ambas têm perdido interesse da sociedade jovem, mais especialmente, mas de modo mais amplo até para adultos também quando se fala em sobrevivência no contexto atual dessas sociedades: prima-se mais pelo trabalho e riquezas (inovações, internacionalização, tecnologias) ao invés de trans-formação sócio-crítico-cultural para revivermos a convivência com os pares. Deste princípio, buscando fazer um resgate dos primórdios básicos da criação/intenção da Universidade, até mesmo da lógica científica, e da arte como relevantes “instâncias” aos processos de trans-formação (para) da(s) vida(s), este trabalho discutirá a crescente derrocada da Universidade e da arte no contexto político-sociocultural atual a fim de comprovar a necessidade de continuarmos acreditando em ambas, mas, ao mesmo tempo, defendendo a necessidade de mudanças nessas como as percebemos/entendemos hoje no século XXI.
Spalling of concrete in fire -an overview and local relevance
Authors: van der Merwe J E
Published: July 2023

Concrete has traditionally been considered as a material with favourable fire resistance. The development of modern concretes with low permeability has, however, resulted in the increased occurrence of spalling when exposed to fire. Recent fire damage in South Africa during the riots in July 2021 resulted in such damage. This paper presents an overview of explosive spalling of concrete in fire, recent local observations, and developments in the field. It is shown that various (often interrelated) factors influence the susceptibility of concrete to spall in fire, and that much research is still needed to fully understand the phenomenon and, specifically, how to accurately predict its occurrence. Recent observations in South Africa support conclusions in the literature that, as an accidental loading case or as life-safety performance criteria, overall structural integrity is rarely compromised. However, as the use of higher concrete grades increases, the relevance of this risk should be considered by practising engineers.
El imaginario cultural en la obra de Gilbert Durand
Authors: Herrera Martha Cecilia , Torres-Carrillo Alfonso
Published: July 2023

La categoría de imaginario, también denominada imaginario social o cultural, no contó con mucho prestigio en el pensamiento moderno y las ciencias sociales clásicas debido a la hegemonía del racionalismo —que dio preeminencia a lo racional y a las ideas claras e indistintas— y del positivismo —que privilegió solo aquellos fenómenos fácticos y observables—. Se deben a Gilbert Durand las elaboraciones más acabadas de esta categoría y su instauración en el campo de las ciencias sociales y humanas para abordar las problemáticas contemporáneas en las que lo simbólico ocupa un lugar central. En esta dirección, este artículo de reflexión aborda la reciente revaloración de la dimensión imaginaria en el pensamiento contemporáneo, para luego abordar la conceptualización elaborada por Durand sobre lo imaginario. Este autor lo entiende como un conjunto de imágenes mentales y visuales con el cual un individuo o una sociedad organizan y expresan simbólicamente sus valores existenciales y su interpretación del mundo. También se exponen los rasgos que le atribuye al imaginario: su fluir transhistórico y magmático, y su capacidad de operar desde una lógica de sincronicidad acausal y recuperar el principio de numinosidad. Finalmente, se presentan algunas posibilidades del uso de los imaginarios en los estudios sociales.

Okul öncesi eğitim, yaşam sürecinde örgün eğitim merdiveninin ilk basamağını oluşturur. Bu basamakta öğrencileri karşılayan okul öncesi öğretmenleri onların ilk öğretmenleri olma özelliğini taşır. Okul öncesi öğretmenlerinin öğrencilerin yaşamlarında ilk kalıcı izler bırakan, özellikle günlük yaşam becerileri, bilgi ve davranışları kazandıran öğretmenler olması onların algı ve görüşlerinin önemini artırır. Okulunun parçası olduğunu düşünen, görüş ve önerileri dikkate alınan, işbirliği içinde ortak amaçlar için hareket eden, okullarında olumlu kültür oluşturulan öğretmenler değerli, önemli olduklarını hissederek performanslarını olumlu yönde sergileme eğilimi gösterir. Bu olumlu enerjinin okulun diğer paydaşları üzerinde bütünleştirici ve sıcak bir yansıma oluşturması beklenir. Okul kültürünün okul öncesi öğretmenleri üzerindeki etkileri nedeniyle çalışmada, onların okul kültürüne ilişkin algılarının metaforlar kullanılarak belirlenmesi amaçlanmıştır. Çalışma nitel araştırma yönteminden fenomonolojik desende yürütülmüştür. Araştırmanın çalışma grubunu Giresun’da kamu bağımsız anaokullarında 2021-2022 eğitim öğretim yılı bahar döneminde görev yapan 50 okul öncesi öğretmeni oluşturmaktadır. Okul öncesi öğretmenlerinin okul kültürüne ilişkin algılarını belirlemek amacıyla ‘Okul kültürü……… gibidir, çünkü ………………..’ ibaresi yazılı yarı yapılandırılmış formlar araştırmanın veri toplama aracı olarak kullanılmıştır. Araştırmada okul öncesi öğretmenleri okul kültürüne ilişkin birliktelik/bütünlük, doğa/doğanın parçası, samimiyet, yiyecek, başlangıç/zamanın parçası, şekillendirici ve yansıtıcı olarak okul kültürü olmak üzere yedi kavramsal kategori altında toplam 42 metafor üretmiştir. En fazla üretilen metaforlar birliktelik bütünlük olarak okul kültürü kategorinde yer almakta olup bu metaforların tümü olumlu yöndedir.

Designing Exploratory Serious Games with Learning Supports
Authors: AKPINAR Yavuz , KUTBAY Ekrem , AKKAYA Ali
Published: July 2023

Serious games are computer games with learning objectives, and present stimulating contexts with interactive, engaging and immersive activities. The brain wave analysis and the neuro-functional correlates of game-based learning revealed that game-based learning is a powerful tool to enliven processes of learning through providing reward and emotional engagement. Implementing a game design model that effectively incorporates game mechanics and pedagogical mechanics is essential in the development of a serious game as an interactive learning environment. The current literature provides many serious game development framework, however, no single framework is sufficient to cover interdisciplinary field of exploratory serious games. This study aimed to develop a framework for designing exploratory serious games. In order to ensure that learners would attain objectives of the learning unit in the game, the proposed conceptual design framework was based upon (a) Kiili’s experiential gaming model (2005), (b) 4C/ID instructional design model (Van Merrienboer, Clark, & de Croock, 2002), (c) ARCS motivation model (Keller, 1987), and (d) Activity theory (Engeström, 1987). The framework pays particular attention on learning support mechanisms of the game because students may have difficulty in, miss or avoid learning curricular content of an exploratory serious game when they focus on merely game mechanics. Finally, the study also stresses and discusses enhancing players’ flow experience and enriching adaptability of the game through design of task regimes.
Prescription and reality in advanced academic writing

The byzantine conventions of advanced academic writing in English are notoriously difficult for graduate students and junior scholars to gain control over. Global higher education and academic publishing have seen a massive expansion in recent years, so that the ability to demonstrate insider disciplinary competence and a grasp of scholarly persuasion has become essential for academic success. With courses in English for Research and Publication Purposes (ERPP) in their infancy and unknown in many countries, writers often turn to the advice of style manuals for guidance. Here they often find recommendations to follow general principles of clarity, brevity and objectivity and are given advice on specific features to achieve this. In this paper we examine three of the most commonly referred to features: demonstrative ‘this’, existential ‘there’ and first-person pronouns. With the aid of a diachronic corpus of articles from four disciplines over the past 50 years, we find that expert use of these features has increasingly departed from the advice in the guides. We describe how the use of these features has changed and stress what instructors in ERPP courses might teach
Understanding students’ approach to discipline-specificity when learning eap writing
Authors: Wang Wei
Published: July 2023

While the teaching of discipline-specific writing has drawn increasing attention in recent EAP writing research, much remains to be investigated regarding what constitutes teaching specificity. This study, adopting a learner-focused perspective, examines how students respond to discipline-specificity when learning in an EAP writing class and what the relationship is between learning the writing of disciplines and general academic writing. It used an in-depth qualitative approach and documented three focal students’ learning trajectories of a business-specific genre – case analysis – in an Academic English for Business course at a Chinese university, drawing on data from interviews, the students’ course reflections, and their multiple drafts of case analysis texts. It was found that the students grasped the genre-specific move structure and the specialized vocabulary of case analysis writing, and they also sharpened their academic skills for business study, including assessing information, applying disciplinary knowledge, and making evaluative analysis. However, the students’ learning of case analysis was affected by problems regarding their general academic writing skills, including argumentation and the formality and clarity of language in the academic written register. The issues of learning disciplinespecific writing in combination with disciplinary ways of knowing and doing, and the interplay between learning discipline-specific and general academic writing are discussed. Pedagogical implications for teaching specificity in EAP writing classes are also suggested
Can comparable corpora be compared?
Authors: López Arroyo Belén
Published: July 2023

Podemos afirmar que, hoy en día, no existe un acuerdo unánime sobre los criterios para compilar un corpus comparable o sobre cómo evaluar la comparabilidad de un corpus. Un corpus comparable es una colección de textos en diferentes lenguas o variaciones que son similares en ciertos aspectos. Pero, ¿en cuáles? Según McEnery y Wilson (2007: 20), la proporción en las muestras, el género, campo y tiempo deben ser los criterios principales a la hora de compilar un corpus comparable y deben ser los mismos en las diferentes lenguas. Sin embargo, estudios previos (López-Arroyo & Roberts, 2017) demuestran que estos criterios pueden no ser válidos en todos los campos. En el presente estudio, analizamos la comparabilidad desde el punto de vista del propósito del corpus. Para ello, hemos compilado un corpus comparable de 150 fichas de cata en inglés y 150 en español escritas por dos autoridades del campo y publicadas en las mismas décadas; según McEnery y Xiao (2007) nuestros subcorpus reúnen todos los requisitos para ser comparables. Sin embargo, nuestra metodología, centrada en el análisis de otros factores tales como El formato, el contenido y el estilo, demostrará que únicamente la proporción, el género, el campo, el tiempo y el tamaño no son siempre suficientes a la hora de comparar corpus
