Se evaluó el comportamiento productivo de gallinas Rhode Island Rojas (RIR) y Plymouth Rock Barradas (PRB), durante el primer ciclo de postura, bajo las condiciones ambientales de la región del Altiplano en el estado de Michoacán, México. Para ello se utilizaron 26 gallinas doble propósito, distribuidas aleatoriamente en dos grupos: 13 RIR y 13 PRB de 20 semanas de edad, colocadas en jaulas individuales convencionales tipo batería; durante el período experimental (noviembre de 2019 a octubre de 2020), recibieron alimento comercial especial para gallinas en postura y agua, ambos ad libitum. Las variables bajo control fueron: peso vivo inicial (PVi), peso vivo final (PVf), consumo de alimento (CA), peso del huevo (PH), porcentaje de postura (%P), huevos por ciclo (HPC), masa de huevo (MH), índices morfométricos (IM), índices productivos (IP). Los resultados más relevantes en los genotipos RIR y PRB fueron: PVi y PVf, 2.019 vs. 2.160 kg y 2.105 vs. 2.300 kg respectivamente (P<0.05); CA, RIR 124.1 vs. PRB 131.8 g (P<0.05); PH y %P para RIR y PRB: 59.4 vs. 61.2 g, 82.5 vs. 64.8 % (P<0.05) respectivamente; HPC y MH: 287.3 vs. 226.8 y 17.217 vs. 13.721 kg para RIR y PRB (P<0.0001) en su orden. En conclusión, las gallinas del genotipo Rhode Island Rojas mostraron mejor comportamiento productivo que sus contemporáneas Plymouth Rock Barradas.

Influence of sodium hydroxide (NaOH) concentration on the behavior of modified 9Cr-1Mo (P91) steel weldment with respect to stress corrosion cracking (SCC) resistance was studied in this work. Weldment of this steel was prepared using a shielded metal arc welding process using modified 9Cr-1Mo electrode followed by weld heat treatment at 1,033 K/1 h. Stress corrosion cracking experiments were performed at 473 K at a strain rate of 1 × 10−6 s−1 in millipore water (MP) (inert medium) as well as in 1 M, 2 M, 3 M, and 4 M NaOH medium. Ultimate tensile strength (UTS), yield strength (YS), and % total elongation (%TE) determined from stress-strain plots were found to decrease with increasing concentration of NaOH. The SCC susceptibility index (Iscc) evaluated using UTS and %TE was highest for the specimen tested in 4 M NaOH. The number density of cracks determined by optical microscopy increased with the concentration of NaOH. Also, it was higher in number in the base metal than in the weld metal. However, at highest concentration of 4 M NaOH, cracks were observed in the heat affected zone of the weld metal. Fractographic studies by scanning electron microscopic showed mixed mode from intergranular to transgranular cracking and vice versa at all concentrations of NaOH. Failure in the base metal was attributed to coarse precipitates, facilitating easy pitting at the precipitate/matrix interface. From the studies it was inferred that weld metal showed better resistance than base metal to SCC in 1 M to 4 M NaOH concentrations.

El Jardín Japonés de Buenos Aires se ha convertido en uno de los paseos turísticos destacados de la ciudad. En él se concentran los principales monumentos de la historia de las relaciones entre ambos países. Por otra parte, su actual administración, ha reunido allí las principales expresiones con las que, en Argentina, se identifica a la cultura japonesa.
Este trabajo busca presentar cómo surgió y por qué también podríamos considerarlo consecuencia de la globalización de la cultura japonesa, qué particularidades tiene la forma de difusión de esta cultura y en el caso de la Argentina, se analizará la forma en que esas expresiones iniciaron lo que podría interpretarse como un proceso de creolización. Es decir qué sucede con las expresiones japonesas cuando se integran en otro contexto cultural, ver no solo su transformación, sino también sus transmisores que dejan de ser japoneses y se convierten en nikkei
Assessment of Item and Test parameters: Cosine Similarity Approach
Authors: CHAKRABARTTY Satyendra Nath 
Published: July 2021

The paper proposes new measures of difficulty and discriminating values of binary items and test consisting of such items and find their relationships including estimation of test error variance and thereby the test reliability, as per definition using cosine similarities. The measures use entire data. Difficulty value of test and item is defined as function of cosine of the angle between the observed score vector and the maximum possible score vector. Discriminating value of test and an item are taken as coefficient of variation (CV) of test score and item score respectively. Each ranges between 0 and 1 like difficulty value of test and an item. With increase in number of correct answer to an item, item difficulty curve increases and item discriminating curve decreases. The point of intersection of the two curves can be used for item deletion along with other criteria. Cronbach alpha was expressed and computed in terms of discriminating value of test and item. Relationship derived between test discriminating value and test reliability as per theoretical definition. Empirical verifications of proposed measures were undertaken.

ABSTRACT
Objective: This study aimed to evaluate the therapeutic effect of Oleanolic acid (OA) on experimentally induced Gastroesophageal reflux disease (GERD).
Materials and Methods: GERD was induced in twelve albino Wister rats by daily administration of 2 mL of acetic acid 15 %, pH: 2.41 for 30 days, while another group of three rats received the same volume of distilled water during the same period. The twelve rats being administered acetic acid were divided into four groups of three rats each and treated as follows; Group 1-the control group, with intra-peritoneal administration of 0.2 mL saline solution; Groups 2 and 3, with intra-peritoneal administration of 0.2 mL of OA 20 mg/kg and 40 mg/kg respectively and Group 4 with oral administration of 2 mL of Lansoprazole 20 mg/kg. All treatments were given simultaneously with the acetic acid daily for 30 days. All rats oesophagus were harvested for histological analysis.
Results: Rats treated with 20 mg/kg and 40 mg/kg OA revealed a more intact oesophageal lining compared to the detached saline group one, there was no damage of blood vessels and the mucosal protective barrier was thick.
Conclusion: Our results suggest that OA may protect the oesophagus against GERD.
De la iconografía histórica al santoral político
Authors: Guerra Gómez Amparo 
Published: July 2021

En las primeras décadas del presente siglo, y coincidiendo con aniversarios y publicaciones ad hoc, triunfan las pantallas televisivas españolas series y miniseries históricas, gracias al auge del biopic desarrollado desde los años 90. Mezcla de ficción y no ficción, este género se constituye en soporte ideal para la representación y (de) construcción de toda una galería de personajes y cargos públicos, constituidos en iconografía y santoral político de la España reciente.
A través del análisis de tres miniseries estrenados en cadenas generalistas,: 23-F: el día más largo del Rey (2009), Adolfo Suárez, el presidente (2010), y De la ley a la ley (2017), el estudio se aproxima a un tipo de representación y de relato sobre los considerados responsables del milagro político del post franquismo. En fechas de celebración del 40 Aniversario de la Constitución Española de 1978, las figuras de la monarquía moderna, del primer Presidente de Gobierno en democracia, y del considerado su arquitecto legal y parlamentario, son mostradas a modo de salvífica trinidad a la medida de una memoria colectiva reciente.
Que tal uma pausa para um "Café Cultural"? Interculturalidade e (trans)formações de identidades de professores de línguas
Authors: Walesko Angela Maria Hoffmann , Portinho-Nauiack Catarina 
Published: July 2021

Este artigo objetiva discutir (trans)formações identitárias de professores de línguas a partir de interações interculturais vivenciadas com falantes nativos de contextos culturais diversos. Para isso, tem como recorte experiências entre professores de inglês em formação inicial e falantes nativos dessa língua durante as edições de 2017 a 2020 do evento de extensão “Café Cultural” na Universidade Federal do Paraná (UFPR), em Curitiba (Paraná). Este estudo, qualitativo e de cunho etnográfico, relaciona esse cenário empírico a concepções teóricas bakhtinianas de língua como discurso e prática social, de ensino-aprendizagem de Inglês como Língua Franca (ILF) e o mito do “falante-nativo”, bem como de interculturalidade e translinguismo e de crenças e identidades docentes. Apresenta, como resultados iniciais, nossas percepções, como professoras-formadoras, sobre como determinadas interações no evento quebraram estereótipos e desmistificaram crenças, formando e transformando o modo como os professores participantes concebiam a língua inglesa e seus falantes nativos e como se identificavam enquanto docentes de inglês. O estudo ressalta, ainda, a importância da promoção de oportunidades de diálogo intercultural entre professores em formação e falantes nativos em busca da legitimação de linguascultura diversas em prol de uma educação em línguas cada vez mais ética e cidadã.
Online Proctoring of High-Stakes English Language Examinations: A Survey of Past Candidates’ Attitudes and Perceptions
Authors: Coniam David , Lampropoulou Leda , Cheilari Angeliki 
Published: July 2021

This paper reports reactions by candidates to the use of online proctoring (OLP), &lsquo;invigilation&rsquo;, in the delivery of high-stakes English language examinations.&nbsp;
The paper first sets the scene in terms of the move from face-to-face to online modes of delivery. It explores the challenges and benefits that both modes offer, in terms of accessibility, fairness, security and cheating.
Evidence is then presented from a survey exploring the reactions to and perceptions of OLP by candidates who had taken an English language examination via OLP. A strong endorsement of OLP was generally recorded. Feedback revealed that respondents perceived OLP to be a more personal as well as a more efficient way of taking a test. Some pertinent negative comments from a smaller number of respondents could be construed as constructive and are also discussed. The results are indicative of a broad acceptance of OLP, pointing to strong future uptake of the OLP mode of test delivery.&nbsp;

Hoe SyRI het belang van transparantie onderstreept
Authors: Selbach Tosja , Brink Barbara 
Published: July 2021

How SyRI stresses the importance of transparency
The Dutch digital fraud detection system SyRI was announced to set up to detect social security fraud quickly and effectively and by doing so, maintain support for the social security system. It was the formal position that for the sake of effectiveness, no information about the algorithm and very limited information about the application of the system should be shared. The authors argue on the basis of a policy analysis, a legal exploration and a literature study that the lack of transparency about the chosen method and the application of the digital fraud detection system in social security can have far-reaching consequences for both the individual and society . The information sharing and the use of algorithms can lead to suspicion of and declining confidence in the government, and a reduced motivation to comply with the prevailing rules. This could undermine the original purpose.
Cancelverhalen: maak het nog wat enger dan die ene slechterik

The blind spot
The most relevant part of a discussion is not what is discussed but what cannot be spoken of. The real taboos are those for which it is taboo to call them taboos. The status quo defines itself as non-ideological while denouncing any challenge to itself as radical.Therefore the column ‘De blinde vlek’ frames the framers, politicizes the status quo and articulates what is not heard of.
Traumatization of the Past and Martyrological Thinking in the Soviet Union and the Post-Soviet Space
Authors:   Moscow State University, Russia, Anikin Daniil ,   Tomsk State University, Russia
Published: July 2021

The purpose of the article is to analyze the mechanisms of the transformation of martyrological thinking in the Soviet Union and in post-Soviet Russia. The methodological basis of the study is constituted by the works written by the representatives of functionalism (E. Durkheim, M. Halbwachs, P. Bourdieu, J.C. Alexander), who raise the issue of the important role of religious rituals and forms of thinking in social space. Martyrological thinking creates martyrdom cults, performing an ambivalent function. On the one hand, this thinking is a way to maintain a collective identity, and on the other, a way to damage and destroy it. The author concludes that in Soviet society two main stages that formed martyrdom cults can be distinguished: the periods of the Civil War and the Great Patriotic War. In both cases, martyrological thinking was an important factor in the consolidation of the society. In post-Soviet society, martyrological thinking becomes a factor that causes the deconstruction of the symbolic space and a hidden factor in the destabilization of the political organization. The perception of the conservative part of the Russian society is expressed in the formation of the cult of the last Russian emperor, Nicholas II, which, on the one hand, allows to mitigate the historical responsibility, and on the other becomes a moral justification for criticizing the continuity of modern Russian power in relation to the Soviet Union.
HepGentox: a novel promising HepG2 reportergene-assay for the detection of genotoxic substances in complex mixtures

Published: July 2021

Background
In risk assessment, genotoxicity is a key factor to determine the safety for the consumer. Most in vitro genotoxicity assays were developed for the assessment of pure substances. However, in recent years more attention has been given to complex mixtures, where usually low amounts of a substance are present. For high-throughput screening, a toxicologically sensitive assay should be used, covering a broad range of genotoxic substances and detecting them at low concentrations. HepG2 cells have been recommended as one of the prime candidates for genotoxicity testing, as they are p53 competent, less prone towards cytotoxic effects and tend to have some metabolic activity.

Methods
A HepG2 liver cell line was characterized for its suitability for genotoxicity assessment. For this, a luciferase based reporter gene assay revolving around the p53 pathway was validated for the analysis of pure substances and of complex mixtures. Further, the cell’s capability to detect genotoxins correctly with and without an exogenous metabolizing system, namely rat liver S9, was assessed.

Results
The assay proved to have a high toxicological sensitivity (87.5%) and specificity (94%). Further, the endogenous metabolizing system of the HepG2 cells was able to detect some genotoxins, which are known to depend on an enzymatic system. When complex mixtures were added this did not lead to any adverse effects concerning the assays performance and cytotoxicity was not an issue.

Discussion
The HepGentox proved to have a high toxicological sensitivity and specificity for the tested substances, with similar or even lower lowest effective concentration (LEC) values, compared to other regulatory mammalian assays. This combines some important aspects in one test system, while also being less time and material consuming and covering several genotoxicity endpoints. As the assay performs well with and without an exogenous metabolizing system, no animal liver fractions have to be used, which application is discussed controversially and is considered to be expensive and laborious in sample testing. Because of this, the HepGentox is suitable for a cost-efficient first screening approach to obtain important information with human cells for further approaches, with a relatively fast and easy method. Therefore, the HepGentox is a promising assay to detect genotoxic substances correctly in complex mixtures even at low concentrations, with the potential for a high throughput application. In a nutshell, as part of an in vitro bioassay test battery, this assay could provide valuable information for complex mixtures.

In 2019 December, a bunch of respiratory disorder cases associated with city’s South China seller spot for sea food of unknown pathology was identified by the health authorities of Wuhan, China. And has been designated a public health emergency of international concern. Consequently, it was concluded that the virus spreads from individual-to-individual, and carriers are the most common source of Coronavirus growth. Novel Coronavirus, SARS–COV-2, was revealed by subsequent investigations and that was the initiative agent now at the core of a major outburst. To prevent or to reduce transmission, special focus and efforts were applied to vulnerable population including elderly people, children and health workers. And large scale measures were taken to lower communicable spread of COVID-19 from surveying a relation of (SARS) Severe Acute Respiratory Syndrome and (MERS) Middle East Respiratory Syndrome, where beta corona virus, which strike the lower respiratory tract and shows pneumonia in human being, was the causative agent. WHO announced outbreak of COVID-19 in the early First light of January 31, 2020 (Korea Standard Time) as “Public Health Emergency of International Concern” (PHEIC).An important collective goal was to reduce the outbreak and to flatten the peak of the outbreak curve. Delays result in significantly higher death tolls. In this review, we are trying to highlight the clinical features, investigations, WHO declaration of PHEIC, mode of transmission, effective Infection protocol to prevent this virulent infection from expansion and WHO 5 Movements because Hand Washing is a way of disinfecting a person’s hands that considerably decreases likely pathogens (deadly germs) on the palms.
