Améfrica Ladina e a crítica à democracia racial em Lélia de Almeida Gonzalez
Authors: Portela Júnior Aristeu , Lira Bruno Ferreira Freire Andrade
Published: June 2022

Resumo Este trabalho se insere no esforço coletivo de promover uma releitura do pensamento político-social brasileiro a partir de autoras e autores cujas reflexões foram historicamente silenciadas em virtude de suas pertenças étnico-raciais e/ou de gênero. Mais especificamente, partimos do pensamento de Lélia de Almeida Gonzalez (1935-1994) para refletir sobre o mito da democracia racial enquanto estruturante de um projeto de nação no Brasil. A questão orientadora aqui é: como a noção de Améfrica Ladina, enquanto fundamento de uma nova leitura da formação da sociedade brasileira, complexifica a crítica ao mito da democracia racial? A hipótese a ser desenvolvida é que o diferencial da crítica da autora está na identificação, ainda nas décadas de 1970 e 1980, de uma tripla forma de discriminação entre raça, classe e gênero que marginaliza brutalmente as mulheres negras - e que não pode ser silenciada na compreensão da formação nacional do Brasil. Ademais, a intelectual em questão ainda apresenta a definição de racismo por denegação como aspecto particular do mito da democracia racial.
Antinegritude: ser negro e fobia nacional
Authors: Soares Maria Andrea dos Santos
Published: June 2022

Resumo Este artigo introduz as proposições da corrente de pensamento conhecida como Afropessimism propondo pensar a questão negra a partir do conceito de antinegritude - que pode ser entendida como a especificidade do racismo dirigido às pessoas negras, e a posicionalidade singular do sujeito negro no mundo inaugurado pela modernidade. Considerando a produção de antropólogos e antropólogas brasileiras oriundas do programa de antropologia da diáspora africana, da University of Texas at Austin, procura-se demonstrar como a antinegritude tem se materializado em esferas da sociedade brasileira como segurança pública, saúde e educação. Nesse sentido, o artigo procura revelar e discutir como antropólogas(os) negras(os) brasileiras(os) oriundas(os) dessa escola têm construído suas análises e revelado as estruturas e dinâmicas de poder racializadas - e especificamente demarcadas pelo que aqui definimos como antinegritude.
As musicovivências do reggae e suas pulsões de (re)existência
Authors: Costa Anderson de Jesus
Published: June 2022

Resumo O presente artigo versa sobre as musicovivências do reggae, enquanto estética musical que emerge das condições impostas pelos processos de colonização, racialização e subalternização na Jamaica. Busco discutir as relações estabelecidas entre os elementos de formação do estilo musical jamaicano e sua constituição como expressão do processo de (re)existências das populações afrodiaspóricas nas Américas. A metodologia de análise utilizada para consecução da pesquisa atrelou dois elementos: uma revisão de literatura, reconstituindo os processos sócio-históricos e culturais que serviram de base para a formação do reggae, e o seu intercruzamento com os elementos biográficos dos principais músicos de reggae jamaicano, entre as décadas de 1960 e 1980. Busca-se assim delimitar a peculiaridade da relação entre música reggae e o cotidiano periférico vivenciado pelos músicos na composição do reggae. Demonstro as condições e estratégias de produção de um estilo que considero outsider, em relação ao estilo estético ocidental.
Ouve, meu filho, o silêncio: a experiência racial de Dorival Caymmi e a epistemologia silenciosa dos candomblés
Authors: Queiroz Vítor
Published: June 2022

Resumo A discussão sobre relações raciais, no Brasil e em outras margens do Atlântico, tende a privilegiar alguns signos exteriorizados, discursos e traços demarcadores da diferença. Porém, a condição de sujeitos reflexivos, capazes de analisar não apenas suas experiências, mas também de pensar múltiplas relações e alteridades, costuma ser negada a pessoas e grupos negros de diversas formas, mesmo na bibliografia especializada. Proponho neste artigo, na contramão dessas duas tendências, uma reflexão de cunho epistemológico sobre as noções de silêncio e segredo, centrais para o candomblé e para outras comunidades afrorreligiosas, a partir da trajetória do músico baiano Dorival Caymmi. Com isso, pretendo evidenciar certas dimensões não ditas, íntimas, dos processos de racialização brasileiros, que incluem o caráter estratégico do silêncio e das alianças solidárias, micropolíticas. Espero salientar, dessa forma, as possibilidades de agência e sobretudo a importância conceitual das ideias e histórias atualizadas pela vivência dos candomblecistas, suas entidades e seus terreiros.

Racional: Há ainda lesões que podem ser perdidas nas colonoscopias. Muitas delas poderiam ser serrilhadas superficialmente elevadas ou deprimidas. Objetivo: Comparar as características histopatológicas destas lesões e seus riscos para carcinoma invasivo para a submucosa. Método: Estudo retrospectivo, transversal, observacional comparando 217 lesões serrilhadas superficialmente elevadas com mais de 5 mm e ressecadas por colonoscopias (G1) com 558 lesões deprimidas (G2). Resultados: As 217 lesões do G1 foram encontradas em 12653 colonoscopias (1,7%) enquanto as 558 do G2 ocorreram dentre 36174 colonoscopias (1,5%). No G1, 63,4% eram mulheres e no G2 não houve predominância de gênero. O tamanho médio foi no G1, 16,2 mm e no G2, 9,2 mm (p<0,001). G1 predominaram no cólon proximal e G2, no distal e reto (p<0,001). No G1, ocorreram 214 (98,6%) neoplasias mucosas de baixo grau e três de alto grau (1,4%). Excluídos 126 pólipos hiperplásicos e considerados os 91 adenomas sésseis serrilhados, no G1 observou- se 88 (96,7%) neoplasias mucosas de baixo grau e três (3,3%) de alto grau, e no G2, 417 (74,7%) neoplasias mucosas de baixo grau 113 (20,3%) de alto grau e 28 (5,0%) adenocarcinomas invadindo a submucosa (p<0,001). Conclusões: As lesões deprimidas apresentaram significativamente mais neoplasias mucosas de alto grau e carcinomas invasivos para a submucosa do que as serrilhadas superficialmente elevadas e mais do que os adenomas sésseis serrilhados superficialmente elevados.
Cone penetration tests in saturated and unsaturated silty tailings
Authors: Russell Adrian R. , Vo Thanh , Ayala Juan , Wang Yanzhi , Reid David , Fourie Andy B.
Published: June 2022

Laboratory-controlled cone penetration test results for two silty tailings in a variety of saturated and unsaturated states, obtained using two calibration chambers, are presented then interpreted using a state parameter-based approach. For each, the cone penetration resistances, which increase due to the presence of suction when the tailings are unsaturated, can be normalised using the initial mean effective stress to establish a relationship with the initial state parameter. The relationship is applicable to saturated and unsaturated conditions, as long as the presence of suction hardening as well as the influence of suction on the mean effective stress are accounted for, and as long as the cone penetrations occur under drained conditions. The relationships enable state parameters to be back-calculated from normalised cone penetration resistances. The state parameters enable estimations of the tailings’ peak friction angles for drained loadings as well as their propensities to liquefy during undrained loadings. Application is demonstrated using cone penetration test soundings in the tailings storages from which the samples were taken, showing how in situ void ratios and state parameters, as well as future state parameters if the tailings were to become saturated, can be determined. Close agreements with direct measurements of void ratios are shown.

EVOLUTION OF THE HYDRAULIC NETWORK AS A FACTOR IN THE FORMATION OF GOLD PLACERS WITHIN THE VISHER-VISIM DEPRESSION IN THE WESTERN URALS
Authors: Kovrizhnykh S.B.
Published: June 2022

A brief history of placer formation and patterns of formation of river valleys in the Mesozoic and Cenozoic are considered. The evolution of the hydraulic net-work, its inception along weakened ore-bearing zones determines the patterns of the position of gold placers in the Western Urals. The formation of gold-bearing placers within the structural-erosion depression is due to the sources of gold, the conditions of their destruction, the erosional incision of river valleys along thrust zones within the Visher-Visim depression. Five types of potentially productive gold placers have been identified, depending on the ratio of the erosional incision of river valleys and gold-bearing eluvium.
AUTHIGENIC MINERAL FORMATION AT THE TOP OF THE CLAY-ANHYDRITE STRATA OF THE VERKHNEKAMSKOE SALT DEPOSIT (IZVERSKY AREA)
Authors: Korotchenkova O.V.
Published: June 2022

The mineral composition and textural features of rocks formed at the boundary between the underlying rock salt and the clay-anhydrite strata of the Verkhnekamskoe Salt Deposit have been investigated. The transformations of sulfate-carbonate rocks revealed here are associated with recrystallization processes that occurred during plastic deformations. All this led to the formation of celestine with an admixture of barium, anhydrite, quartz and pyrite. Crystallization of newly formed minerals oc-curred due to hydrolysis of aluminosilicate material and sulfate reduction

Published: June 2022

The article considers the geological aspects of engineering-geological surveys at the construction site of an underwater river crossing over the Kama River with a length of more than 700 meters. For the first time, an unmanned aerial vehicle has been effectively used to conduct engineering and geological surveys in the study area. The second innovative technology applied at the site was underwater echo sounding of the river bed and bottom. During surveys at the construction site of the crossing, the capabilities of a complex of traditional methods of engineering-geological surveys (geomorphological, geophysical, hydrogeological, physical-mechanical, etc.) were combined with innovative technologies: the use of a drone for reconnaissance and selection of the crossing site and echolocation of the river bottom to ensure minimization of the risks of destruction object. The passage of argillite-like calcareous sandy light hard clays of the Kazan stage (engineering-geological element-8) along the horizon is substantiated.

Published: June 2022

Solid inclusions in chromite grains of Geofizicheskoe VII deposit located in Dzharlybutak area hosting the largest ophiolitic chromitite resources in the world are described. We show that mineralogical composition of inclusions (olivine, serpentine, chlorite, pargasite, PGM, base metal sulfides) is more various in comparison to that of host ultramafic rocks (olivine, enstatite, serpentine). PGM are predominantly disulfides of refractory PGE, rarely – native Ru-Os-Ir solid solutions. PGM inclusions always locate in chromite grains and they often form intergrowth with chlorite. We infer that the inclusions in chromite grains would been formed by solid state processes (deformation-induced breakdown of pyroxenes, impurity segregation in spinel, etc.) during high-T plastic flow and recrystallization at upper mantle conditions.

TITANIUM-MAGNETITE DEPOSITS AS A PROMISING RAW MATERIAL BASE FOR METALLURGY IN THE URALS (BASED ON THE EXPERIENCE OF DEVELOPING THE KACHKANAR GROUP OF DEPOSITS)
Authors: Buzmakov V.N. , Volodina Y.V.
Published: June 2022

Since the depletion of reserves of magnetite ores, profitable for mining, the role of titanomagnetite ores increases. In addition, the presence of V2O5 in the ores significantly increases their value, which is why the deposits are used only for the ex-traction of vanadium, and titanium and vanadium go to the waste of metallurgical pro-duction. If the titanium cannot be removed to the proper extent, then the ores are not mined. However, for the successful application of modern technologies for processing the ores of these deposits, it is necessary to take into account a number of mineralog-ical and genetic factors, and as a result, to conduct technological research at the early stages of geological study of ore objects. Even in the process of assessing a deposit, it is necessary to consider not only the enrichment technologies, but also the metallur-gical processing, as well as to carry out geological and technological mapping, which will effectively manage the quality of products at all stages of the production process.

Published: June 2022

A study of 11 samples of sandstones, mudstones, limestones from copper occurrences in the villages of Yug and N. Lyady, Perm region, was carried out using the ICP-MS method. It was found that the instrumental rocks are relatively barren, enriched in Cu, Ag, Au, Cd, V, Os, Ru, Rh. An analysis of the results obtained made it possible to show that the Ufa deposits of the Middle Urals are quite comparable with the Tatar deposits of the Orenburg Cis-Urals, differing from them in a larger share in the petrofund of the area of demolition of basic and felsic rocks. It was suggested that some of the Permian copper was transported in the form of vanadates, and the Orenburg copper - in the composition of chromates under strongly oxidizing conditions. The low contents of light REEs in the accompanying mudstones, as well as the low contents of titanium in all sedimentary rocks, suggest that the areas of drift of clastic material were covered by significant weathering changes.
Existence and Intellect in Nicholas of Cusa

Published: June 2022

Varlığın mahiyeti meselesi, insanın varlığa hangi açıdan muhatap olduğu ile doğrudan ilgilidir. Felsefe tarihinde ortaya çıkmış olan farklı ekoller arasındaki ayrımı oluşturan da, temelde bu mesele karşısındaki tutumlarıdır. Nicholas of Cusa düşüncesinde varlık, insanın salt epistemik yetileri ile vukufiyet kesp edebileceği bir alan değildir. Bundan dolayı Mutlak Varlık, olduğu haliyle kendi mükemmelliği içerisinde kavranamaz. Bunun için öncelikli olarak gerekli olan, aklın bütün olumlayıcı bilgi iddialarından vazgeçtiği bir tür zihinsel arınmadır. Bu, aslında bir bilinç durumudur ve bu düzeye erişen idrak, varlığı kendi kaynağında temaşa eder. Zıtlığın uyumda, çoğulluğun ise birlikte herhangi bir çelişki olmaksızın göründüğü bu hâl içerisinde, Tanrı artık bir bilgi konusu olmanın ötesinde bir tecrübe konusudur. Cusa’ya göre, insanın iç tecrübesinden hareket eden mistik karakterli bir varlık görüşü ile ancak idrake dayalı yetkin bir bilinç sağlanabilir. Burada artık asıl olan bilme değil, asla bilemeyeceğini bilmedir. Cusa’ya göre, bu idraki seviyeye ulaşmanın yolu ruhsal bir eğitimin yanında Tanrısal lütuftur.
Descripción del desarrollo ontogénico inicial de la dorada Brycon moorei (Characiformes: Bryconidae)
Authors: Villada Julieth , Castañeda-Álvarez Germán , Jiménez -Segura Luz F.
Published: June 2022

La ontogenia está relacionada con la presencia de nuevas características o pérdida de rasgos ya existentes; poco se conoce de la ontogenia de peces andinos. Brycon moorei pertenece a la familia Bryconidae. En las épocas de mayor pluviosidad, migran hacia pequeñas quebradas y riachuelos, con el fin de reproducirse. Este trabajo tiene como objetivo analizar el desarrollo ontogénico inicial de B. moorei. Las muestras fueron obtenidas de parentales mantenidos en cautiverio. Se registraron las horas post-fertilización HPF en las que aparecen estructuras. La vesícula ótica fue evidente a las 14 HPF, la cápsula óptica a las 9 HPF, la vejiga natatoria a las 48 HPF, la abertura de la boca a las 23 HPF y del ano se observó a las 24 HPF. La duración de las fases durante el periodo embrionario: clivaje (4 h), gastrulación (3 h), embriogénesis (7 h) y, del periodo larval: larva vitelina (28 h), pre-flexión (61 h), flexión (80 h) y post-flexión (>170 h). En cada periodo y fase se realizó el análisis de su forma usando medidas de distancia. Las longitudes de las larvas tuvieron un aumento considerable con las HPF. El número de miómeros totales se mantuvieron constantes a partir de la pre-flexión. Estos resultados pueden usarse para explicar el panorama general de los primeros estadios embrionario y larval en condiciones de cultivo, pueden ayudar al desarrollo de mejores métodos de cría de larvas en la producción y a encontrar caracteres diagnósticos que puedan utilizarse en la taxonomía.
Investigación de restauración ecológica en bosques Andinos Colombianos: un análisis bibliométrico y vacíos de información
Authors: Rodríguez González Iván Camilo
Published: June 2022

La investigación es la base para el desarrollo de estrategias de restauración ecológica y por tanto tiene responsabilidad por la frecuencia del fracaso de esta práctica. La investigación experimental se considera una de las herramientas más poderosas para establecer la causalidad de un fenómeno ecológico y proveer información relevante en términos de gestión de ecosistemas. En este trabajo se realizó una revisión del conocimiento científico específico en restauración ecológica de bosques andinos y alto andinos, con el fin de realizar un análisis a partir de indicadores bibliométricos de importancia (Índice de Price, Índice de aislamiento e Índice de colaboración) e impacto científico (índice de inmediatez e Índice de impacto de las publicaciones) y posteriormente, identificar vacíos de información respecto a la investigación experimental. Se analizaron 186 documentos, entre artículos científicos, documentos técnicos, libros, secciones de libro y tesis de grado. En general, la investigación experimental en términos de restauración ecológica en bosques andinos y alto andinos, solo se utiliza en 17% de las investigaciones, con especial énfasis en estudio de flora. Los vacíos de información más grandes, derivados de investigación experimental, se encuentran en los campos de la agroecología, socioeconomía y estudios multitemáticos o multidisciplinares. La mayoría de las investigaciones experimentales corresponden a documentos técnicos o tesis de grado, con resultados parciales o no publicados, por lo que el potencial de generación de conocimiento en restauración ecológica es alto, siempre y cuando las investigaciones se culminen y se realicen con suficiente rigor científico.
Daños estructurales de las injusticias epistémicas. El caso de la Iglesia católica
Authors: Cely Ávila Flor Emilce
Published: June 2022

En este texto expongo las consecuencias estructurales generadas por las continuas y sistemáticas injusticias epistémicas llevadas a cabo en determinadas comunidades o instituciones. Estas injusticias contribuyen a construir una estructura de silenciamiento, negación de autoridad epistémica, encubrimiento e impunidad. Se expondrá la importancia del aspecto normativo que guía las reflexiones acerca de estas injusticias en dos sentidos: por un lado, en tanto es necesario contar con criterios que permitan establecer la verdad en el marco de evaluación de injusticias epistémicas y, de otro, en el sentido de precisar la manera en que atentar sistemáticamente en contra de esta produce daños epistémicos casi irreversibles y garantiza la perpetuación de la estructura. Se mostrará cómo sucede esto en el marco de una institución poderosa como es la Iglesia católica, que desde hace décadas exhibe un patrón de injusticias testimoniales y de encubrimiento de abusos en su interior.

Published: June 2022

El estrés ha sido una de las reacciones de mayor impacto ante las medidas de aislamiento social originadas por la covid-19. Así pues, el objetivo de esta investigación fue describir el nivel de estrés percibido en estudiantes universitarios durante la cuarentena decretada por la pandemia de covid-19. Para ello, se trabajó bajo un enfoque cuantitativo con alcance descriptivo, un diseño no experimental y un corte transversal a través de la aplicación de la escala de estrés percibido (eep-10). Asi mismo, se contó con la participación de 213 estudiantes de Santander, Colombia. Con relación a los resultados, se plasmaron las medidas de tendencia central, como también se identificaron diferencias de género, siendo las mujeres quienes presentan mayores niveles de esta reacción. Finalmente, se concluye que la presencia de estrés en altas cotas está correlacionada con otros factores que tienen graves incidencias en la salud mental de los universitarios, lo que exige con urgencia el diseño y ejecución de programas preventivos e interventivos, junto a un enfoque de género.

Published: June 2022

Introduction. Inadequate sleep hygiene (SH) is considered factor contributing to insomnia. However, the practice of SH by depressed patients with comorbid insomnia has not been explored. Objective. We aimed to compare the practice of SH between patients with major depression, comorbid insomnia, primary insomnia, and good sleepers. Method. One hundred and eighty-two adult individuals participated: 62 outpatients with major depressive disorder with comorbid insomnia (MDD), 56 outpatients with primary insomnia (PI), and 64 good sleepers (GS). All participants were assessed with a structured psychiatric interview, an insomnia interview, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and the Sleep Hygiene Practice Scale. We compared the practice of SH as a whole and by domains between the groups and the relation between SH practice, insomnia, and sleep quality. Results. Patients with PI and MDD showed a significantly worse practice of global SH. In the comparison by SH domains, MDD and PI groups had significantly worse scores than GS in all domains. Individuals with MDD showed a significantly worse practice of sleep schedule and arousal related behaviors than PI group. Although, SH practice was significantly related with insomnia and sleep quality in the whole sample, this association remained significant only in the PI. The arousal-related behaviors domain was the main predictor of insomnia and sleep quality. Discussion and conclusion. Although patients with insomnia comorbid with MDD or with PI have a worse SH practice than GS, only arousal-related behaviors and drinking/eating habits contribute significantly to insomnia severity and sleep quality.

Introduction. The rapid spread of the pandemic due to the SARS-CoV-2 virus, more commonly known as COVID-19, required sanitary measures, such as social distancing and quarantining, which represented non-normative stressors for Mexican families. Objective. Obtaining evidence of the validity and reliability of a family coping scale in the face of the COVID-19 pandemic. Method. A questionnaire was developed containing 48 items, and responses were collected using Google forms with a total of 558 participants. Exploratory and confirmatory factor analyses were conducted to obtain the reliability and validity of the scale. Results. The instrument is made up of six factors that explain 67.27% of the variance. The scale had a McDonald’s omega coefficient of .82, and the model had a good fit with most values equal to or higher than .90. Discussion and conclusions. The final items showed proper theoretical congruence and good indicators of fit. These results allow for the assertion that factors 1, 2, 5, and 6 allude to a good family adaptation in the face of the pandemic. Meanwhile, factors 3 and 4 indicate a poor family adaptation. Among the main contributions of this study is that this is one of the first scales to address the subject in Mexico, followed by statistical data that suggests the scale possesses appropriate psychometric properties to be used in the Mexican population.
Oil-Sponsored Exhibitions and Canada’s Extractive Politics of Cultural Production
Authors: Sharp Camille-Mary
Published: June 2022

Focusing on the Canadian Museum of History’s newest permanent exhibition, The Canadian History Hall (2017), and its sponsorship by the Canadian Association of Petroleum Producers (), this article discusses oil-sponsored museum exhibitions and the extractive politics within which Canadian culture is produced. This article begins with an overview of The Canadian History Hall and the activist response to its sponsorship by Big Oil. It then situates the exhibition within a larger history of oil and museums in Canada, reflecting on the controversial, Shell-sponsored The Spirit Sings (1988) exhibition at the Glenbow Museum. The article argues that, as it reproduces the longstanding relationship between Canadian museums and the oil industry, the Canadian Museum of History’s recent partnership exemplifies the ongoing role of extractive politics in cultural production. While European museums increasingly face pressures to divest from fossil fuels, the entanglement of culture and extractive interests in Canada suggests the need for a unique and critical approach to sponsorship in Canadian cultural institutions.

Authors: Agishina Tatiana А. , Kontsevaya Anna V. , Gambaryan Marine G. , Drapkina Oksana M.
Published: June 2022

AIM: Tо assess the impact of anti-tobacco measures under federal anti-tobacco law on the hospital admissions for pneumonia of various diagnoses, and other acute respiratory infections of the lower respiratory tract, bronchial asthma, and asthmatic status in the Samara, Arkhangelsk regions, and the Chuvash Republic.
MATERIAL AND METHODS: A retrospective analysis of monthly hospital admissions for pneumonia (ICD-10 J12J18), and other acute respiratory infections of the lower respiratory airways (ICD-10 J20J22), asthma (ICD-10 J45), and status asthmaticus (ICD-10 J46) was carried out in the three selected regions of the Russian Federation from the 1st of January, 2012, till the 31st of December, 2017, and in subgroups (014, 1559, 60 years, and older). The analytical approach used was the interrupted time series method, which was performed using the STATA 15.0 software package.
RESULTS: From this study, it was revealed that there was a decrease in the hospital incidence of respiratory airways infections after each stage of enacting the anti-tobacco policy in all the three selected regions of the Russian Federation. In the Arkhangelsk region, this decrease amounted to 19% in 2013, and 22% in 2014. In the Samara region, 20% and 23% respectively, and the Chuvash Republic, 31% and 39% respectively. A significant decrease in hospital admissions for asthma and status asthmaticus was observed only in the Chuvash Republic (the decrease occurred by 11% in 2013, and by 12% in 2014). In other regions, the observed decrease was not significant.
CONCLUSION: From this study, the results obtained have shown that the anti-tobacco measures introduced in Russia in 2013 and 2014 were responsible for the decrease in the number of hospitalizations for lower respiratory airways infections within the same period.
Variations of human heart bioelectrical signals at hypoxic exposure
Authors: Bocharov Mihail I. , Shilov Aleksandr S.
Published: June 2022

BACKGROUND: In the area of physiology and medicine, special emphasis is placed on the study of hypoxic conditions. Hypoxic responses of some major physiological systems, including blood circulation, are described. However, the cardiological component of these individual responses, and their variability at different levels of acute hypoxia (AH) remains a poorly-studied aspect.
AIM: To study the individual characteristics of the response types in conjugated ECG parameters, and their variations at different stages of mild and medium AH.
MATERIAL AND METHODS: The experiments were performed on male subjects (1826 years old) divided into two groups (n1=30 and n2=29), who were exposed to AH of 14.5% at 12.3% O2 for 20 min. Amplitude (P1II, RII, T1II, BAL, BAR) and temporal (RR, QT) ECG parameters, and blood oxygenation (SpO2) were determined at AH periods (at 5, 10, and 20 min respectively). In subgroups (clusters), the features of types with low and high responses, and their stability in AH are described.
RESULTS: Clustering of ECG variations with AH of 14.5% and 12.3% O2 identified two subgroups (clusters), that differed at least in the magnitude of the decrease in the total BAL and RR. With AH of 14.5% O2, the number of different ECG parameters between subgroups gradually increased: at 5 min BAL (p 0.001), at 20 min RII (p=0.047), T1II (p=0.016), BAL (p 0.001), RR (p=0.035), QT (p=0.008), and with AH 12.3% O2 only BAL (p 0.001). It was found that at all periods of AH of 14.5% O2, in 60% of individuals, the type of response remained. Regarding AH of 12.3% O2 in 55.2% of the other cases, the type of response of ECG parameters changed. At the same time, no parallels were observed between the types of reactions and deviations in SрO2.
CONCLUSION: From this study, It can be assumed that there are two types of conjugated reactions of ECG parameters in response to mild and medium AH, and their variability is absent in 40% and 44.8% of cases, respectively, as well as the independence of differentiation of ECG responses types from hypoxemia.

LATAR BELAKANG

 

Plantar fasciitis merupakan salah satu penyebab nyeri paling sering di daerah tumit pada orang dewasa. Kondisi ini merupakan suatu peradangan yang terjadi akibat adanya microtrauma yang terjadi secara berulang ulang. Nyeri yang muncul biasanya paling terasa saat pertama kali berdiri pada pagi hari, atau setelah menumpu pada kedua kaki dalam jangka waktu yang lama. Indeks massa tubuh (IMT) salah satu faktor yang dinilai dapat berkontribusi dalam timbulnya plantar fasciitis. Namun demikian  sampai saat ini masih terdapat pro dan kontra pendapat mengenai peran  IMT tersebut. Studi ini bertujuan untuk melihat hubungan antara kedua variabel tersebut dengan plantar fasciitis.

 

METODE

Penelitian ini merupakan penelitian analitik yang dilakukan dengan pendekatan potong lintang atau crosssectional untuk melihat adanya hubungan antara IMT dan  kejadian plantar fasciitis.  Data yang diambil merupakan data sekunder dari salah satu RS Swasta di  Wilayah Tangerang dengan periode waktu antara bulan Agustus sampai Oktober 2021.Pengujian data di analisa dengan  menggunakan uji Fisher exact dengan batas kemaknaan < 0,05.

This study evaluated the milk production and persistence of the crossbreed Holstein cow during lactation. The study was conducted at the Balcashi and Chambo herds located in the Chimborazo province at an altitude of 2980 m.s.n.m. and an average temperature of 11ºC. The research included 88 first-time heifers maintained on a rotational grazing system inside an electric fence. The feeding was based on Lolium multiflorum, Dactylis glomerata, and Trifolium pratensis. Milk production was recorded and analyzed by lactation thirds, peak, and persistence using descriptive statistics. Weekly production was measured using the fifth-order regression model. The results showed that in the first third of lactation, the production was 1559.75 ± 181.25 liters of milk, the cost per feed consumption of $1.91, an income of 5.32 dollars per day, and a benefit of 2.78. The curve of production in the first lactation, productivity, and weekly increase responded to a fifth-order model. The authors concluded that the best feed conversion, weekly production, income, and cost-benefit were reached in the first third of lactation.
Keywords: lactation, persistence, peak production, third lactation.

Published: June 2022

The objective of this study was to compare the two methods of reproduction used for the Alpine goats at a sheepfold located in the province of Pichincha. A hormonal protocol was followed for heat synchronization based on intravaginal sponges impregnated with fluorogestone acetate (FGA) combined with prostaglandin F2α (PGF2α) and equine chorionic gonadotropin (eCG). In total, 24 two-to-four-year-old does were randomly divided into two groups: one for natural breeding (NB) with a five-year-old male goat of proven fertility and another for intracervical artificial insemination (IC-AI) with refrigerated semen collected from the same goat. The parameters evaluated were: the conception rate (CT), the fertility rate (FR), and the prolificacy index (PI). The CT and FR were compared using Pearson’s Chi-square test, while PI was analyzed with the student’s t-test. None of the reproductive parameters evaluated showed a significant difference between the two methods of reproduction. Therefore, MN or IC-AI in goats with previously synchronized heat could be an alternative to improve reproductive efficiency.
Keywords: estrus synchronization, artificial insemination, natural mating, Alpine, goats.
RESUMEN
El objetivo de este estudio fue comparar dos tipos de técnicas reproductivas en un aprisco ubicado en la provincia de Pichincha en cabras de raza Alpina aplicando un protocolo hormonal para sincronización de celo basado en esponjas intravaginales impregnadas con acetato de fluorogestona (FGA) combinado con prostaglandina F2α (PGF2α) y gonadotropina coriónica equina (eCG). Se utilizaron 24 hembras de 2 a 4 años de edad, divididas de manera aleatoria en dos grupos: uno para monta natural (MN) con un macho cabrío de 5 años de edad, de fertilidad probada, y otro para inseminación artificial intracervical (IA-ic) con semen refrigerado obtenido del mismo macho cabrío. Los parámetros productivos evaluados después de la realización de los dos tipos de técnicas reproductivas fueron: tasa de concepción (TC), tasa de fertilidad (TF) e índice de prolificidad (IP). La TC y la TF se compararon mediante la prueba de Chi cuadrado de Pearson, mientras que el IP fue analizado con la prueba de t student. Ninguno de los parámetros reproductivos evaluados mostró diferencia significativa entre ambos tipos de reproducción. Por lo tanto, la MN o la IA-ic en cabras con celo previamente sincronizado podría ser una alternativa para mejorar la eficiencia reproductiva.

Asertive Communication in the Food Industry: A Case Study on the Use of a Natural Beta-carotene Dye in Foods and Its Economic Impact
Authors: Ávalos María Belén Bravo , Herrera Carlos Andrés Mancheno , Álvarez Luis Fernando Arboleda
Published: June 2022

Food safety has gained great importance in recent years. Food marketing has significantly influenced the eating habits of our society, which proves the importance of real-time and authentic communication. As a result of it, an urgent need has arisen in the food industry to find substitutes for additives that can potentially cause toxic or allergic reactions in humans. In addition, the so-called “functional foods” have introduced new trends in the demand and production of foods. One such trend has been the substitution of artificial colorants with beta-carotene – a natural colorant with a strong pigmenting power. However, many countries including Ecuador have still not been able to exploit this colorant at industrial levels as a total substitute for artificial colorants. Therefore, this analytical study concludes that an assertive communication is relevant for the industry, as investigated in this practical case.
Keywords: communication, food industry, beta-carotene, economic impact.
RESUMEN

Authors: Novillo José Francisco Falconí , Rogel Carlos Jefferson Valdiviezo , Cando Lenin Javier Ramírez
Published: June 2022

The araza, also known as quince or Amazon guava, is a climacteric fruit typical of the Ecuadorian Amazon region. The fruit has a vitamin A, B1, and C content of 7.75%, 9.84%, and 74%, respectively, with the vitamin C content being twice that of the orange. However, as a fruit that needs to be stored at 90% humidity, it is very perishable. Therefore, the current study was carried out to determine the physicochemical characteristics, thermal properties, and freezing time of the fruit through mathematical models using the RStudio software to simulate the freezing process and thus preserve the vitamin content. The arazá freezing time was 2.98 hr at –18ºC, which is well within the normal parameter for freezing fruits while maintaining their nutritional characteristics.
Keywords: araza, thermal properties, freezing, Rstudio.
RESUMEN
El arazá conocido también como membrillo o guayaba amazónica es un fruto climatérico propio de la región amazónica ecuatoriana que posee un contenido de vitamina A, B1 y C de 7,75%; 9,84% y 74% respectivamente, sobresaliendo el contenido de vitamina C cuyo porcentaje es el doble que el que posee la naranja, sin embargo, al ser un alimento con un 90% de humedad es muy perecible, por lo que se determinaron las características físico – químicas, propiedades térmicas y tiempo de congelación de la fruta, mediante modelos matemáticos empleando el software RStudio para simular el proceso de congelación y de esta manera preservar el contenido vitamínico. El tiempo de congelación del arazá fue de 2,98 h a -18∘C y está dentro del parámetro normal para frutas en el cual se mantienen sus características nutricionales.
