Combustible de Aviación Sostenible (SAF), como alternativa para la reducción de gases de efecto invernadero en el sector aeronáutico en el Perú
Authors: Bravo Artica José Luis
Published: November 2024

La industria aérea, responsable del 2,5% de las emisiones globales de CO2 y otros gases nocivos, busca reducir su impacto ambiental. El aumento en la demanda de vuelos ha llevado al Reino Unido a contemplar un aumento del 10% en los precios de los boletos para gestionar la demanda y reducir vuelos comerciales. Los biocombustibles, especialmente el Combustible de Aviación Sostenible (SAF), destacan como alternativas prometedoras al ser fabricados con recursos renovables y al utilizarse en algunos aeropuertos. Un estudio evalúa los beneficios del SAF en la reducción de emisiones de gases de efecto invernadero, comparándolos con combustibles fósiles en términos de costos y rendimiento. En 2019, en Perú, el uso de SAF demostró una reducción del 28% en emisiones. La investigación se centra en la viabilidad de los biocombustibles, especialmente el SAF, para disminuir emisiones en la industria de la aviación. La metodología implicó comparar las emisiones de combustibles fósiles con SAF al 30%, elaborado con aceite usado de cocina, logrando una reducción del 28% en las emisiones de gases de efecto invernadero. A pesar de las ventajas del SAF, se destacan desafíos como el alto costo y el rendimiento comparativo con combustibles convencionales, subrayando la necesidad de abordar aspectos económicos para una implementación efectiva.

Authors: Arteaga Chango William Francisco , Arias Villamarin Alicia Ángela , Andrade Mantilla Fernanda Dayana , Llerena Carrera Gerardo Marcelo
Published: November 2024

La investigación se fundamenta en la recopilación bibliográfica y experiencias de campo desarrolladas un largo periodo de tiempo dentro del distrito minero "Ponce Enríquez", ubicado en las estribaciones de la Cordillera Occidental en el sur del Ecuador, provincia del Azuay. Desde los años 80 en este distrito minero se han extraído minerales de valor económico, principalmente, oro, plata, cobre y zinc, cambiando drásticamente la economía de la región.Mediante la información recolectada se ha identificado que este distrito minero es conocido por depósitos de Au principalmente en estructuras (vetas y vetilleos), brechas hidrotermales, stockworks y diseminaciones, relacionadas con pórfidos (±Au, Cu, Mo). La edad de mineralización del distrito minero se estima del Mioceno Medio al Superior. Es una faja metalífera que se extiende aproximadamente 100 km en dirección NE-SW, asociada con los cinturones metalogénicos de Ecuador y Perú (con pórfidos conocidos como La Granja, El Galeno, Conga, Cerro Corona, entre otros) y guarda similitudes con depósitos en Colombia (La Colosa).
Variaciones de alfa-amilasa salival relacionadas con edad, sexo e índice de masa corporal en estudiantes universitarios
Authors: Juárez Rolando Pablo Alejandro , Celía Armando Cesar
Published: November 2024

Objetivo. Determinar la presencia y dirección de la relación entre alfa-amilasa salival (AAs), edad, sexo e índice de masa corporal (IMC) en adultos jóvenes. Métodos. Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.

Authors: Villacres Boris , Carvajal Juan , Rockenbach Maria Cristina , Carvajal Camila
Published: November 2024

Objective. Determine the antimicrobial efficacy of Lysol® and quaternary ammonium during the evaluation of three critical areas of the dental unit (control tray/buttons, dental chair back, and triple syringe handle). Methods. Through a cross-sectional comparative experimental study, a total of 8 dental chairs were analyzed: three were disinfected with Lysol®, three with quaternary ammonium, and two armchairs were selected as controls (positive and negative). All dental chairs were sampled twice a day: before use and at the end of use, for three days. Sampling was carried out at the Hemisferios University Clinics before and after the application of the disinfectant. The samples were transported in thioglycollate broth for analysis. 1:2 and 1:10 dilutions of each sample were plated on Plate Count Agar and incubated for 24 hours at 37°C. Subsequently, duplicate colony counts were performed, analyzing a total of 864 samples. Results. Lysol® and 5% quaternary ammonium showed equal antimicrobial effectiveness against the three areas analyzed (p>0.05). The area with the highest number of microorganisms was the tray (including control buttons). Conclusion. It was determined that both Lysol® and 5% quaternary ammonium are highly effective in eliminating microorganisms present on the critical surfaces of the dental unit. Furthermore, the tray, including the control buttons, was found to be the most contaminated area before treatment.
Identificación de Leishmania spp en caninos de tres departamentos del centro de Colombia y su correlación clínica
Authors: Lopez-Medina Nova Katherine , Rondon-Barragan Iang Schroniltgen
Published: November 2024

The species Leishmania infantum and L. chagasi are considered causal agents of visceral leishmaniasis, a relevant disease due to its zoonosis and severity in humans. Canines are the main reservoirs, hence the need to implement precise diagnoses to identify the Leishmania species involved. The aim of the study was to perform a molecular diagnosis of leishmaniasis (conventional PCR and Sanger sequencing) in 29 tissue samples from canines clinically suspected of leishmaniasis, previously diagnosed by non-molecular methods. The presence of the parasite could be identified by PCR in 9/29 samples (L. infantum, n=4; L. chagasi, n=4; L. braziliensis, n=1), evidencing a predominance of L. infantum and L. chagasi in canines with cutaneous and mucocutaneous leishmaniasis. The PCR allowed to clarify previously negative diagnoses; however, limitations were found, such as the absence of Leishmania DNA in some samples and the inability to obtain additional samples due to inaccessibility to patients. Despite these limitations, the study highlights the importance of molecular diagnosis to identify the species causing leishmaniasis.
Factores que influyen en la inseminación artificial con semen fresco en alpacas (Vicugna pacos)
Authors: Cardenas Suares Nilton , Catacora Flores Nuvia , Pacheco Curie Joel , Garcia Vera Wilber
Published: November 2024

The aim of the study was to evaluate factors that affect the fertility of artificial insemination (AI) with fresh diluted semen in alpacas. In Exp. 1, females with preovulatory follicles with diameters ≥7-≤ 9 or ≥10-≤12 mm were inseminated; in Exp. 2 the females were inseminated at 24, 26, 28 and 30 h after ovulation induction; In Exp. 3, alpacas were inseminated with semen at four concentrations: 15, 25, 35 and 45x106 sperm/ml; and in Exp. 4, using the best results from the previous experiments, 350 alpacas were inseminated in two peasant communities. Semen was collected by the post-copulatory method, using ejaculates with motility ≥60%, diluted in Tris-glucose-citric acid and egg yolk. Alpacas with preovulatory follicles ≥7 mm were selected for AI. Ovulation induction was done with a GnRH analogue and pregnancy diagnosis was made 30 days after service. Pregnancy rate was not affected by follicular size. AI 24 to 26 h after ovulation induction obtained a higher pregnancy rate (50 and 55%, respectively; p<0.05) compared to those inseminated at 28 and 30 h (35 and 30%). AI with 15x106 sperm/ml resulted in low pregnancy rates (30%) compared to 35 and 45x106 sperm/ml (50 and 55%, respectively). In the peasant communities, 55% pregnancy rate was obtained. The results suggest that the success of AI with fresh semen in alpacas is highly dependent on sperm dose and timing of insemination.
Variabilidad de la frecuencia cardiaca en caninos saludables, adultos, y residentes en hipoxia hipobárica (Bogotá, 2600 metros sobre el nivel del mar)
Authors: Guerrero S. Claudia Marcela , Eduardo Cruz Luis , Vargas-Pinto Piero
Published: November 2024

Heart rate variability (HRV) refers to beat-to-beat fluctuations in heart rate and represents the neurovegetative and endocrine influence on the heart. In the present study, HRV values were obtained in healthy adult canines of both sexes, residing in the city of Bogotá (2600 meters above sea level). Time-domain and frequency-domain HRV parameters were obtained using 60-minute Holter recordings. The distribution of the data was determined using the Shapiro-Wilk test. The dogs were distributed into two subgroups to study their behaviour in relation to sex and age. ANOVA and Kruskal Wallis tests were used to determine statistical differences. In general, the mean HRV values differ from those reported by other authors in studies at sea level and at lower altitudes. The differences in HRV in relation to sex were significant in the RMSSD and pNN50 parameters. There were no differences in the relationship between HRV and age.
Methods of corpus analysis of the frequency and dynamics of language units in 2024
Authors: Borzenko Ekaterina
Published: November 2024

The article “Methods of corpus analysis of the frequency and dynamics of language units in 2024” presents possible methods and sources of searching, frequency analysis and diachrony (microdiachrony, nanodiachrony) of Russian language units using not only well-known linguistic corpora such as RNC and GICR, but also “natural corpora” of Yandex (including Yandex. News) and Google, as well as other search sources, such as LiveJournal, VKontakte and Telegram. The author indicates the possibility of using the official English-language corpora in the study of loanwords-neologisms in the modern Russian language. There is a discussion of the pros and cons of each service with special attention to the search tools that allow a linguist to specify the data. In the article there also are considered search services in the databases of digitized books: in Google Books (including the Google Books Ngram Viewer) and the electronic catalog of the Russian State Library. There is a presentation of the services (Yandex. Wordstat and Google Trends) that show user interest in a language unit – a word or phrase. All or almost all of the services, the possibility of using which is analyzed in the article, have already been used in one way or another in linguistic analysis in scientific papers. However, it should be considered that, firstly, it is often necessary to use several sources at once for an adequate analysis, and, secondly, the choice of priority sources depends on the type of the information a linguist is looking for. Conclusions are drawn about the possible order of use of the services discussed for different categories of words (long-known; words of the Runet era; very new and rare words; words for which it is necessary to find out the frequency by half-year or by month) and the need to be able to use each of these tools is justified.
A dictionary of locutons from liturgical books by protopriest A. I. Nevostruev (понасилую — посредѣ)
Authors: Davydenkova Maria , Kaluzhnina Nadezhda , Strievskaya Maria , Strievskaya Olga
Published: November 2024

The “Dictionary of Locutions from Liturgical Books” by Protopriest A. Nevostruev, completed in the middle of the 19th century and never published, can be regarded both as a significant achievement of Church Slavonic studies and as a valuable lexicographic source. The manuscript is kept in the Russian State Library. The decrepit state of the manuscript has determined the necessity of its urgent study and edition. The significance of this project is primarily due to the fact that the text of the dictionary is being made accessible to linguists for the first time. The orthography and grammar of the dictionary reflect the linguistic views of the time of its creation and can be of interest for those who study the history of Russian linguistics. This paper contains the 6th part of dictionary entries beginning in letter P. The characteristic features of the publication of this Dictionary, the lists of sources, abbreviations and symbols were described in detail in the previous issues of St. Tikhon’s University Review. All previously published parts of the Dictionary together with the critical apparatus can be found at the website of St. Tikhon’s University for the Humanities.
Artificial intelligence wrote a fairy tale: simulation of text impact against the background of natural word-containing semiosis
Authors: Vdovichenko Andrey
Published: November 2024

Artificial intelligence (AI) is developed and improved as a “"language model”" of natural intelligence (NI). A superficial understanding of the relationship between text and meaning-making may be misleading regarding the capabilities and actions of AI. In this article, the AI phenomenon is presented within the framework of a communicative rather than a linguistic paradigm. The theoretical basis of the communicative approach can be considered the concepts of semiotic impact and the cognitive state of a semiotic actor, which are the cause of the generation of signs and meaning-making in natural semiosis (including word-containing, grapheme-containing, or textual). Postulating a system of semantic-formal modules “"sign body-meaning”" in the linguistic paradigm provokes an incorrect interpretation of the AI phenomenon, as a result of which the sign sequence (text) itself, corresponding to autonomous linguistic rules, becomes a sign of thinking (intelligence). The linguistic interpretation of AI is a problem (misunderstanding of the causes and consequences of AI “speaking”), which is removed by using a communicative approach.
G. Hauptmann’s novel «Phantom» and its cinematic embodiment
Authors: Voronovsky Alexander
Published: November 2024

The article deals with the theme of the interaction of literature and emerging cinema on the example of the work of the prominent German writer Gerhart Hauptmann (1862–1946). He was one of the first to see in the new art new opportunities for self-expression. Hauptmann’s attitude to cinema was ambiguous and changed over the years, but finally his direct involvement in the film adaptations of his works determined the nature of his artistic pursuits. Inspired by the new ideas the German writer returned to his unfinished novel «Phantom» (Phantom, 1922). Despite the exact reproduction of the storyline, the film director Friedrich Wilhelm Murnau and screenwriter Thea von Harbow adapted seriously Hauptmann’s work to their needs. In particular, the accents in the interpretation of the problem of individual freedom are changed, the central character is viewed differently. The director, using brilliantly the visual possibilities of cinematic art, emphasizes the themes and motifs crucial for Hauptmann. Murnau stresses the role of the unconscious discussing the origins of the spiritual enslavement of individual. The director shows how the person loses his self-control due to irrational forces. In the film he demonstrates the private world of the «nervous» person, moving away from the external reality into the world of hallucinations. He shows the central character frustrated and confused in front of the subconscious. In addition, Murnau, unlike Hauptmann, associates the human loss of self-control with the late 19th and early 20th century popular problem of the war of the sexes with its irrational and even demonic elements. Hauptmann’s novel, initially coldly received by critics who reproached the writer for its predominantly entertaining nature, was later reevaluated largely because of Murnau’s interpretation.
Cross vs. Serpent. Different approaches to the interpretation of the theme of Serpent and Cross (Gen 3; Num 21; John 3. 14) in early Christian and Gnostic sources
Authors: Nesterova Olga
Published: November 2024

The article examines the peculiarities and fundamental differences in the approach to the interpretation of a group of biblical narratives, united by the theme of the serpent and the tree, in the exegesis of the Gnostic sects of the "Ophite" (from Greek ophis - "serpent") currents and in Christian typological exegesis. The interpreters who belonged to the Grate Church (as opposed to "heretical" movements) were guided by the text of John 3:14, where Jesus compares Himself to the brazen serpent who had saved the people of Israel in the wilderness from death caused by the bites of poisonous serpents. The correlation of this text with the complex of prophetic "testimonies" about the Saviour "hanging on a tree" allowed them to see in it a reference to Christ's crucifixion. However, the same image of the brass serpent evoked inevitable associations with the story of the temptation of Adam and Eve, which also featured the "tree" and the "serpent". The soteriological doctrine of most Gnostic sects was based on the idea of salvation through "knowledge", so the Gnostics did not share the biblical concept of the Fall of Man, considering the access of Adam and Eve to the fruit of the Tree of Knowledge as a beneficial act and reassessing from this point of view the role of the biblical serpent, which in church sources was associated mainly with the Devil. The most interesting position in this respect was taken by the followers of the sect of "Perates", who regarded the "ancient serpent", the bronze serpent of Moses and Jesus as epiphanies of the divine Son-Logos, i.e. the spiritual Christ. In the biblical story of the Tree of Knowledge they saw the reflection of the conflict between the God-Demiurge together with his subordinate archons, who were hostile to human salvation, and the higher spiritual power acting through the serpent, which was further reproduced in the story of the transformations of the rod of Moses, in the story of the Brazen Serpent, in the story of Joseph and his brothers, and in the story of Jesus, who was crucified by the Jews, the worshippers of the Demiurge. In contrast to the Ophites, the Church exegetes sought to exclude the possibility of establishing a symbolic link between Christ and the serpent of Genesis. Taking the figure of the Brazen Serpent as a type of the Crucifixion, they correlated it not with the image of the Tree of Knowledge, but with the image of the Tree of Life, from which they developed an independent line of types of the Lord's Cross, based on the adjoining motifs of tree-wood and staff-rod, which in turn determined the character of the typology of Baptism, where the two above-mentioned motifs were combined with the motif of water.
Staging Heart Failure with Preserved Ejection Fraction by Assessing Cardiac Chamber Involvement
Authors: Shchendrygina Anastasia , Giverts Ilya , Tokmakova Mariya , Kharchenko Ekaterina , Vlasova Alisa , Rogova Anastasia , Zakharov Nikita , Mukhina Nadezda
Published: November 2024

The management of heart failure with preserved ejection fraction (HFpEF) remains largely unresolved due to our limited understanding of the underlying mechanisms of the pathology and the challenges in accurately phenotyping this heterogeneous syndrome. A paradigm shift is required to personalise care and unify our approaches to HFpEF patients for future clinical trials. Accordingly, we propose a staging classification for HFpEF based on the identification of the involved cardiac chambers by echocardiography.

O presente trabalho objetiva analisar as atualidades nos artigos publicados sobre formação de professores e o processo inclusivo de alunos com altas habilidades e superdotação. Quanto às categorias metodológicas, o trabalho possui abordagem qualitativa, optou-se pelo método procedimental revisão narrativa da literatura. Em relação à etapa de filtragem e seleção, foram selecionados um total de quatorze artigos que comporão o escopo textual de discussão sobre a temática mencionada, o recorte temporal estabelecido foi 2021 a 2024 (últimos quatro anos). Destaca-se que a busca dos trabalhos para a análise foi realizada nas seguintes bases: Portal Periódicos da Capes, Directory of Open Access Journals (DOAJ), Scientific Electronic Library Online (SciELO Brazil), Google Acadêmico e Web of Science. Os resultados evidenciaram a relevância de trabalhos voltados à formação inicial e continuada enfatizando uma perspectiva inclusiva, uma vez que pesquisas relacionadas a este público ainda são exíguas, e há muitas concepções historicamente errôneas e segregadoras.  Por fim, conclui-se que a temática formação de profissionais da educação é vital para a inclusão bem-sucedida de alunos com altas habilidades e superdotação, pois aumenta sua capacidade de identificar, apoiar e acolher esses alunos dentro do sistema educacional.
From the Village to the Táncház: The Revival Metamorphosis of a Peasant Flute Player
Authors: Salamon Soma
Published: November 2024

During an inevitable rural-to-urban conforming process, the Hungarian revival movement, known as táncházmozgalom, has left marks of change on the knowledge of tradition bearers, which is the very source and condition of its existence. The aim of preserving original cultural frames of music and dance in its new environment was obvious, and still active village musicians and dancers have been respected (or even idolized) as the protagonists of the movement from the onset. Still, their original social roles as well as the status and function of their knowledge have been misinterpreted in multiple cases. Despite deliberate attempts to maintain authenticity, the result is a brand-new milieu with new musical phenomena, differing greatly from the original forms of musical tradition. The case study presented here concerns one of the last living Hungarian peasant musicians, András Hodorog. He and his unique technique of playing the furulya (flute) are highly regarded in the movement. After nearly two decades of recording, learning, and researching Hodorog's flute technique, comparatively monitoring changes in his instrumental style and repertoire, I have discovered that certain aspects of his musical profile would not have evolved without the impact and demands of the Hungarian revival movement.
Among-population variation in sexual size dimorphism of Nepa cinerea (Heteroptera: Nepomorpha)
Authors: Bakonyi Gábor , Seres Anikó
Published: November 2024

Nepa cinerea is a common aquatic predator. It is widely distributed in various aquatic biotopes of the Palaearctic. Body size is an important trait that impacts the fitness and survival of animals and thus their evolution. Like most insects, N. cinerea males are smaller than females, but sexual size dimorphism (SSD) has not been investigated. We investigated the extent of SSD, the validity of Rensch's rule, and morphological differences between nine populations based on 51 morphological parameters. Females were found significantly and marginally significantly larger than males in all but one population. However, no difference in body length was found between the populations. Population had a significant effect on 12 traits for females and only on 5 for males, showing that females are more variable than males. Specifically, differences were found in the length of the second and third leg pairs. We did not find any support for the Rensch's rule. Nevertheless, female body size and SDI (sexual dimorphism index) were positively correlated. We suggest that fecundity selection accounts for female-biased SSD in N. cinerea.
Korean Religious Texts in Iconic and Performative Rituals
Authors: Yoo Yohan
Published: November 2024

This book examines the ways in which scriptures are accepted and appropriated by religious people in Korea. It explores how sacred texts in various religions, including Protestantism, Buddhism, Confucianism, and Shamanism, attain their sacred status and power. It also delves into how the performative aspect of scriptures is often intrinsically linked to their iconic status. The book highlights the close relationship between the performative use and the iconic nature of these scriptures, showing how they are ritualized and performed in religious practices. In Korea, a distinct mix of religions coexists, each contributing to the country’s religious diversity. Christianity, as the largest religion, represents a significant portion of the population, yet Buddhism, as Korea’s major traditional religion, holds a comparable influence. Confucianism, with its deep historical roots and impact on Korean customs and values, continues to shape the society, particularly through ancestral rites and customs that prioritize elders. Many contemporary Koreans still resort to shamanic rituals and divinations, which have prevailed among the common people for thousands of years. Examples from these religions in Korea vividly illustrate that the iconic and performative dimensions of scriptures are generally witnessed in religions that recognize sacred texts. The interplay and complementary functions of these dimensions in the lives of the religious are also examined. The book presents compelling examples showing how the content, physical form, recitations, written characters, and imagery of scriptures are ritualized to exert sacred power.
Acolhida da Igreja Metodista aos imigrantes venezuelanos: uma perspectiva decolonial
Authors: Fonseca do Nascimento Fabio , De Franco Clarissa
Published: November 2024

Este artigo é resultado da pesquisa de mestrado que investigou os princípios e práticas de acolhimento da Igreja Metodista aos imigrantes venezuelanos no Brasil. As imigrações venezuelanas tornaram-se pauta política, social, religiosa e midiática, o que explica o interesse e demanda por este tema nos estudos de religião. O artigo propõe uma reflexão sobre o acolhimento da Igreja Metodista aos imigrantes sob a perspectiva decolonial, abordando alguns aspectos pós-coloniais e a teologia do compromisso social wesleyano. Para atingir este objetivo, trouxemos as vozes dos principais expoentes da Igreja Metodista que trabalham com projetos socais que acolhem a população imigratória no Brasil. Destaca-se neste artigo uma análise crítica sobre a ambivalência presente no entendimento da missão metodista como colonialista e ao mesmo tempo contracultutral da lógica hegemônica. Esta análise parte do olhar sobre as práticas de acolhimento aos imigrantes venezuelanos desenvolvidas pela Igreja Metodista, apresentando considerações para aprofundar a reflexão na perspectiva decolonial.
A religião na pós-modernidade: uma análise psicanalítica
Authors: Brandão Hugo
Published: November 2024

Objetivamos compreender como a negação da figura de alteridade da Transcendência e a atual crise de legitimação característica da pós-modernidade têm impactado na Religião. Para tanto, partimos de uma análise psicanalítica, uma vez que a psicanálise nos oferece, especialmente a partir de Jean-Pierre Lebrun, importantes subsídios para entendermos parte desse fenômeno de luta por oferta de gozo pleno no campo religioso, a partir de sua observação do declínio da Transcendência enquanto figura de alteridade, gerando uma crise de legitimação e de autoridade na pós-modernidade. O que tem gerado uma mutação do laço social que resulta em todas as transformações percebidas com o advento da pós-modernidade, as quais impactaram decisivamente no fenômeno religioso e como demonstraremos, acarreta mudanças na Religião e nas experiências religiosas, em um duplo movimento: negação da Transcendência como representância de limites e/ou ressiguinificação da mesma.
Debatendo o conceito de κεφαλὴ em 1Cor 11,3
Authors: Gonzaga Waldecir , Dantas da Silva Júnior Marcelo
Published: November 2024

O presente artigo aborda as novas possibilidades interpretativas para o vocábulo “cabeça” usado pelo apóstolo Paulo em 1Cor 11,3. Durante anos, uma hermenêutica religiosa patriarcal hierarquizou os gêneros usando textos como esse para difundir e popularizar uma supremacia masculina. Entretanto, hodiernas pesquisas acadêmicas têm produzido novas possibilidades para o entendimento da metáfora paulina. Entre as mais difundidas estão a ideia de origem e de proeminência. Assim, este artigo procura apresentar os argumentos favoráveis e desfavoráveis para cada uma dessas novas visões. Por fim, observa-se, a partir de uma visão libertadora e cristocêntrica, qual opção promove a humanização, a ressignificação do ser e a igualdade entre os gêneros.
Paulo e a forma do discurso farisaico
Authors: Gomes SIlvio
Published: November 2024

As informações sobre a seita farisaica estão presente nos evangelhos e na Mishiná e no Talmude. Essas fontes, porém, não podem ser confiáveis para uma reconstrução histórica da seita. Os evangelhos estão em disputa, em momentos de tensão e reproduzem o farisaísmo como se fossem um grupo uníssono, hipócrita e representava o mau judeu. Não são confiáveis como o Talmude não o é para falar sobre Jesus, historicamente. Por outro lado, nem ele e nem a Mishiná podem ensinar sobre o farisaísmo de forma segura, posto que algumas mudanças ocorreram em resposta ao cristianismo e mesmo em resposta às mudanças do próprio judaísmo rabínico, filho do farisaísmo, depois do II século, data da escrita da Mishiná. Paulo, portanto, confiados na informação dele mesmo, foi um fariseu, e pode ser o elo que faltava para a reconstrução do que seria um fariseu antes de 70. A análise do discurso pode ajudar a identificar as “coincidências” dos discursos paulinos e do Talmude que podem apontar para a preservação, ainda que disforme, do discurso farisaico original.

Resultados: los puntajes medios del instrumento Conocimiento, Actitud y Práctica resultaron inadecuados antes de la intervención educativa; después de la intervención, permanecieron inadecuados, pero con discreta mejora; la actitud mostró una inadecuación acentuada. Dicho instrumento, antes de la intervención, se asoció con edad, escolaridad, número de embarazos y haber realizado prenatal; después de la intervención, además de estas, tuvo asociación con otras variables, como lugar de residencia, estar estudiando y haber usado método contraceptivo. Los tres dominios tuvieron asociación entre sí antes y después de la intervención. Conclusión: la intervención educativa, mediada por la enfermera, fue efectiva para promover conocimiento, actitud y práctica de las puérperas adolescentes en el uso adecuado de la minipíldora como contracepción posparto.
Household availability and sources of carotenoids important to health in Brazilian urban centers by income in 2017/2018
Authors: Padovani Renata Maria , Amaya-Farfan Jaime
Published: November 2024

ABSTRACT Objective Low carotenoid intake is associated with the incidence of chronic noncommunicable diseases. Given the large diversity and specificity of chemical structures and functions, along with the wide Brazilian geodiversity, it should be important for health to examine the cross-sectional distribution of carotenoid availability. Considering family incomes, the authors have calculated and analyzed the individual household availability of α-carotene, β-carotene, β-cryptoxanthin, lycopene, and lutein/zeaxanthin according to income in the eleven largest Brazilian urban centers in 2017-2018. Methods Data from the Brazilian Institute of Geography and Statistics’ latest Family Budget Survey on monetary food acquisitions and food composition tables were used to calculate the individual carotenoid contents of both vegetable and animal food sources. Results The family acquisitions of carotenogenic foods showed to be insufficient for most families living in these urban centers, except Salvador, Belem, Belo Horizonte, and Porto Alegre, where certain key-carotenoid sources did reach the higher income groups. The main foods identified that contributed to the supply of carotenoids were carrot and common squash (α-carotene), common squash, carrot, scallion/parsley, mango, and tomato (β-carotene), papaya, orange, and tangerine (β-cryptoxanthin), tomato sauce, tomato paste, guava, watermelon and papaya (lycopene) and scallion/parsley, kale, egg, corn meal and corn flakes (lutein/zeaxanthin). Conclusion Based on the home availability of specific carotenoids estimated in the present study, it is concluded that the population was not reasonably well protected against chronic diseases given the low acquisition of key carotenoid sources in these urban centers, especially among the lower-income class.

Published: November 2024

ABSTRACT Objective Resting metabolic rate is an important measure for nutritional monitoring in anorexia nervosa. This study aims to investigate the differences in resting metabolic rate measurements across various methods between underweight and recovered anorexia nervosa patients, as well as healthy controls. Methods Participants were categorized into three groups: active anorexia nervosa, recovered anorexia nervosa, and healthy individuals. Indirect calorimetry, the gold standard for resting metabolic rate measurement, was used to evaluate the performance of the Harris-Benedict, Schebendach, FAO/WHO, and Buchholz equations. Body mass index and fat free mass were also measured. Mean and median resting metabolic rate values across evaluation methods were compared, and Bland-Altman plots along with percent difference tables were employed to compare the different methods. Results In the active anorexia nervosa group, the Buchholz, Harris-Benedict, and FAO/WHO equations overestimated resting metabolic rate, whereas the Schebendach equation did not. In the recovered anorexia nervosa group, Schebendach’s equation underestimated resting metabolic rate, while the other equations, with the exception of FAO/WHO, did not. Bland-Altman analysis supported the adequacy of the Schebendach equation in active anorexia nervosa. In recovered anorexia nervosa, proportional biases observed for the Harris-Benedict, Buchholz, and FAO/WHO equations indicated its inadequacies for this group. Conclusion In patients with active anorexia nervosa, the results indicate that the Schebendach equation may be adequate for estimating resting metabolic rate. However, none of the equations showed adequacy for estimating resting metabolic rate in recovered patients.

ABSTRACT This review discusses observed hydroclimatic trends and future climate projections for the Amazon. Warming over this region is a fact, but the magnitude of the warming trend varies depending on the datasets and length of the analyzed period. The warming trend has been more evident since 1980 and has further enhanced since 2000. Long-term trends in climate and hydrology are assessed. Various studies have reported an intensification of the hydrological cycle and a lengthening of the dry season in the southern Amazon. Changes in floods and droughts, mainly due to natural climate variability and land use change, are also assessed. For instance, in the first half of the 20th century, extreme flood events occurred every 20 years. Since 2000, there has been one severe flood every four years. During the last four decades, the northern Amazon has experienced enhanced convective activity and rainfall, in contrast to decreases in convection and rainfall in the southern Amazon. Climate change in the Amazon will have impacts at regional and global scales. Significant reductions in rainfall are projected for the eastern Amazon.

It is well known that prolonged rainwater erosion can adversely affect the surface texture of asphalt pavements, leading to a rapid decline in their skid resistance. This study utilized a small-scale accelerated loading device, a high-precision 3D scanner, and digital image processing technology to investigate the surface texture wear process and skid resistance decay trends of basalt asphalt pavement and steel slag asphalt pavement under water erosion and traffic load. The results indicate that under submerged conditions, the skid resistance (BPN) of asphalt pavement declines rapidly during the first 500,000 load cycles, and the rate of decline gradually stabilizes after 500,000 cycles. After 1.2 million load cycles, the BPN of basalt pavement decreased by 28.10%, while that of steel slag pavement decreased by 21.18%, indicating that the skid resistance of steel slag pavement is significantly better than that of basalt pavement. Texture parameters—namely, root mean square height, peak material volume, core material volume, void volume of the core, and valley void volume—exhibited the same decay trend as BPN. The average correlation coefficients between BPN and texture parameters were 0.846, 0.848, 0.898, and 0.916, respectively, indicating that texture parameters can be used as evaluation indicators for skid resistance decay. Finally, the decay of pavement skid resistance was predicted using an exponential decay equation.

To enhance the bioactive functionality of viscose fabrics by way of a new eco-friendly approach, novel green zinc oxide nanoparticles (ZnO-NPs) were biosynthesized and incorporated as functional additives in the finishing formulations encompassing citric acid as a green cross-linking agent and sodium hypophosphite as a potential catalyst using pad-dry-cure method. For this purpose, ZnO-NPs were biosynthesized using zinc acetate as a processor and our formerly prepared and fully characterized starch nanoparticles having particle size ranged of 80–100 nm as a green reducing and stabilizing agent for substituting the traditionally used toxic reducing agents. The Zetasizer determined that the ZnO-NPs were approximately tailored at 18–20 nm in size, while the ultraviolet–visible spectra revealed highly symmetric single-band absorption with a maximum peak around 382 nm. In contrast, both Fourier transform infrared spectroscopy and scanning electron microscopy of finished viscose fabric in the presence of ZnO-NPs-III confirm the presence of ZnO-NPs and the formation of agglomerated nanostructures on the fabric surface. The finished fabric had an ultraviolet protection factor of 34.07 compared with 4.0 for untreated fabric, and the antibacterial activities had very good bacteriostatic activity against Staphylococcus aureus and Escherichia coli bacteria, compared with zero for untreated fabric. Furthermore, how the finishing bath ingredients interact with the fabric was projected.

There are some special features in calorimetry signal introduced by the ferromagnetic ↔ paramagnetic phase transitions in magnetic materials. The purpose of this study was to investigate, by means of high-resolution differential scanning calorimetry, the effects of heat flux change during direct and reverse second-order phase transformations of the type ferromagnetic ↔ paramagnetic in some high-purity metals possessing natural ferromagnetism: iron, cobalt, and nickel. The literature review indicates that so far there has been no research describing such phase transitions with the help of differential scanning calorimetry. Our study detected anomalies in the dependences of heat flux intensity on temperature. There was noted a shift to the region of higher temperatures during heating in the range of thermocycling rates of 5-10-20-40 K/min. A shift to the region of lower temperatures during cooling in the same range of thermocycling rates was observed in the area of registration of second-order phase transition. The possibility of using calorimetric measurements for estimating the Curie temperature at ferromagnetic ↔ paramagnetic transitions in the metals is shown. The authors highlight that, when conducting high-resolution calorimetric measurements, it is essential to take into consideration in the total heat flux balance the possible contribution from the effects associated with second-order phase transitions, including, in particular, ferromagnetic ↔ paramagnetic transitions.

Oil-well equipment for oil production operates under complex and changing circumstances. Well pressure and temperature can reach 100 MPa and 200 °С. Chemicals are pumped into oil-wells to enhance oil yield. However, this leads to an accelerated corrosion and contributes to the equipment breakdown. Adverse effects on the equipment can be decreased through use of protecting coatings with multi-function properties.Epoxy coatings are popular. However, they are limited by operating temperature of 130 °C. If the temperature is exceeded, epoxy coatings lose their protective properties. However, researches claim that the heat resistance can be modified through epoxy resin fillers. This allows to create new composites with advanced properties. To create composites that can function under an elevated temperatures we need to research the components selection further.The article describes how the composite components influence its heat resistance. The research is based on the Wick's method. The composites matrix is ED-16, ED-20 and ED-22 epoxy-diane resin. The hardeners are PO-300, HT-450 and PEPA. The fillers are carbon nanotubes, carbon fiber, carbonaceous filament and graphene. If we add fillers to the composite based on ED-22 and HT-450 hardener, the heat resistance doubles compared to the unfilled cured resin. It is hypothesised that the epoxy free groups or hardener's free aminogen groups effect the heat resistance, because these groups can react with the fillers and result its spacious structure. This effects the composites properties.The findings serve as the basis for developing composite coatings for oil-well equipment to protect it against harsh environment.
