Cultura y história en exílio: las obras de Otto Maria Carpeaux e Villém Flusser

Esta ponencia esta inclusa en una investigación más amplia cuyo objectivo es hacer una análisis desde a producción de intelectuales que llegarán en Brasil como exilados entre los dos conflictos mundiales. Brasil es frecuentemente visto como un país de inmigrantes o viajeros, y no a través de la mirada del exilado. Como si el país no había recibido un importante grupo de exilados y que muchos de ellos no han dejado importantes relatos de su condición de desplazamento. El exilio impregna la literatura como una metáfora, incluso siendo considerada como el arquetipo de la situación del escritor o artista. Hace importante recordar aquí Adorno cuando dice que el sentimiento de extrañeza, de no sentirse en casa estando en casa, es la única postura moral aceptable. Si analizamos la literatura y la producción intelectual de los exiliados en Brasil a lo largo del siglo XX, encontramos ejemplos de todas estas manifestaciones de la condición impuesta en la eliminación del exilio. Esta comunicación se centra en la experiencia del exilio dos intelectuales importantes, a saber: Otto Maria Carpeaux y Flusser Villem. El primer, austriaco y católico, fue un importante crítico literario en Brasil entre los anos de 1945-1968, el segundo, checo e judío, tiene una obra filosófica reconocida internacionalmente.Instituto de Investigaciones en Humanidades y Ciencias Sociales (IdIHCS

First description of Echinococcus ortleppi and cystic echinococcosis infection status in Chile

Cystic echinococcosis (CE), a parasitic disease caused by the cestode Echinococcus granulosus sensu lato (s.l.), is a worldwide zoonotic infection. Although endemic in Chile, information on the molecular characteristics of CE in livestock remains scarce. Therefore we aimed to describe the status of infection with E. granulosus s.l. in cattle from central Chile and also to contribute to the study of the molecular epidemiology of this parasite. According to our results, the prevalence of CE is 18.84% in cattle, similar to previous reports from Chile, suggesting that the prevalence in Santiago Metropolitan area has not changed in the last 30 years. Most of the cysts were found only in lungs (51%), followed by concurrent infection in liver and lungs (30%), and only liver (19%). Molecular characterization of the genetic diversity and population structure of E. granulosus s.l. from cattle in central Chile was performed using a section of the cytochrome c oxidase subunit 1 (cox1) mitochondrial gene. E. granulosus sensu stricto (s.s.) (G1-G3 genotypes) was confirmed by RFLP-PCR to be the dominant species affecting cattle (284 samples/290 samples); we also report for the first time in Chile the presence of E. ortleppi (G5 genotype) (2 samples/61 samples). The Chilean E. granulosus s.s. parsimony network displayed 1 main haplotype. Additional studies using isolates from many locations across Chile and different intermediate hosts will provide more data on the molecular structure of E. granulosus s.s. within this region. Likewise, investigations of the importance of E. ortleppi in human infection in Chile deserve future attention

New insights of the local immune response against both fertile and infertile hydatid cysts

Background Cystic echinococcosis is caused by the metacestode of the zoonotic flatworm Echinococcus granulosus. Within the viscera of the intermediate host, the metacestode grows as a unilocular cyst known as hydatid cyst. This cyst is comprised of two layers of parasite origin: germinal and laminated layers, and one of host origin: the adventitial layer, that encapsulates the parasite. This adventitial layer is composed of collagen fibers, epithelioid cells, eosinophils and lymphocytes. To establish itself inside the host, the germinal layer produces the laminated layer, and to continue its life cycle, generates protoscoleces. Some cysts are unable to produce protoscoleces, and are defined as infertile cysts. The molecular mechanisms involved in cyst fertility are not clear, however, the host immune response could play a crucial role. Methodology/Principal findings We collected hydatid cysts from both liver and lungs of slaughtered cattle, and histological sections of fertile, infertile and small hydatid cysts were stained with haematoxylin-eosin. A common feature observed in infertile cysts was the disorganization of the laminated layer by the infiltration of host immune cells. These infiltrating cells eventually destroy parts of laminated layer. Immunohistochemical analysis of both parasite and host antigens, identify these cells as cattle macrophages and are present inside the cysts associated to germinal layer. Conclusions/Significance This is the first report that indicates to cell from immune system present in adventitial layer of infertile bovine hydatid cysts could disrupt the laminated layer, infiltrating and probably causing the infertility of cyst

Physical activity, grape juice, red wine and resveratrol effects in cardiac remodeling of Wistar rats submitted to a high fat diet

Background: The association between regular physical activity and the polyphenol-rich drinks in models with a high fat diet, has not been sufficiently elucidated. Objective: The objective was to study the effects of the association among regular physical activity and polyphenol-rich drinks consumption in lipid profile and cardiac remodeling of Wistar rats submitted to the high fat diet. Methods: Rats Wistar, 90 days, 05 groups (n=10/group): Control Group (CG); High Fat Group (HG); Resveratrol Group (RG); Grape Juice Group (JG); Red Wine Group (WG); HG, RG, JG and WG received a high fat diet (20%). The animals performed a treadmill running protocol for 60 days. After, blood was collected for biochemical evaluation and heart was removed for histological analysis. Variables were expressed as mean ± standard deviation. ANOVA one way and Bonferroni or Tuckey`s as post-test, when appropriate, p < 0.05. Results: JG show higher total cholesterol (72.0 ±8.9 p<0.05) and HDL (28.0 ± 2.0 p<0.05) in relation to CG (total cholesterol = 57.8 ± 8.1, HDL = 24.4 ± 2.9). Collagen concentration: HG (9.65%, p<0.05) presented higher concentration in relation to the CG (3.68%), RG (4.73%), JG (3.57%) and WG (6.59%). Conclusions: It is concluded that the association between physical activity and drinks rich in polyphenols was able to protect the heart tissue from damage caused by the high fat diet

Milling of the Phosphate Rock Flotation Circuit Circulating Load Aiming Production Increase and Iron Content Reduction in the Final Concentrate

Phosphorus has its main application in the production of phosphoric acid, being the apatite series its main ore. The Brazilian main phosphorus reserves are igneous, as is the case of Catalão alkaline dome, were Copebras/CMOC International has operations. The content of P2O5 in the ROM has been reduced over the years and, as a consequence, the content of the contaminants in the concentrate, produced by flotation, which enhances the difficulty in the phosphoric acid production. Only traces of arsenic, iron, and heavy metals can be present in high-purity phosphoric acid. The circulating load of the Copebras’ phosphate rock flotation circuit was submitted to bench scale flotation tests with addition of a milling step were carried out in order to increase the recovery of P2O5 and the reduction of the Fe2O3 content to values below 5%. Samples were collected from the flow composed by the scavenger concentrate and cleaner tail, with d95 \u3c208 \u3eμm and average content of 26.2% of P2O5 and 13% of Fe2O3 (6% hematite, 5% goethite, 1% magnetite, and 1% ilmenite) and comminuted in a pilot pant rod mill. Three samples with different d95 (2O3 content (for the sample with d95 \u3c150 \u3eμm). The industrial implementation of a milling stage of the flotation circulation load and a subsequent flotation of this material has the potential to increase the overall process efficiency by approximately 5.5%, resulting in a production increase of 62,000 tons/year of phosphate rock concentrate, with higher quality than the one currently produced. The phosphate rock flotation tailings feeds a niobium processing plant, a co-product of extreme importance due to its economic value. The proposed circuit increased the niobium liberation degree and its content in the produced tailings, which will probably lead to a higher recovery of the same

Atlantic mammal traits: a dataset of morphological traits of mammals in the atlantic forest of south America

Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species, but also within species. Mammals are an interesting group for investigating trait-based approaches because they play diverse and important ecological functions (e.g., pollination, seed dispersal, predation, grazing) that are correlated with functional traits. Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from −5.83 to −29.75 decimal degrees of latitude and −34.82 to −56.73 decimal degrees of longitude in the Atlantic forest of South America. We present trait information from 16,840 individuals of 181 species of non-volant mammals (Rodentia, Didelphimorphia, Carnivora, Primates, Cingulata, Artiodactyla, Pilosa, Lagomorpha, Perissodactyla) and from 23,010 individuals of 98 species of volant mammals (Chiroptera). The traits reported include body mass, age, sex, reproductive stage, as well as the geographic coordinates of sampling for all taxa. Moreover, we gathered information on forearm length for bats and body length and tail length for rodents and marsupials. No copyright restrictions are associated with the use of this data set. Please cite this data paper when the data are used in publications. We also request that researchers and teachers inform us of how they are using the data.Fil: Gonçalves, Fernando.

Interference of iron on soil boron determination with azomethine-H in acid solutions

A busca de métodos que permitam a extração do boro para avaliação da fertilidade do solo para a recomendação de adubação é importante, devido aos baixos teores de boro e aos altos teores de Fe na maioria dos solos brasileiros. A extração com água quente, método-referência, é trabalhosa e apresenta dificuldades operacionais. Por outro lado, soluções de CaCl2 5 mmol/L e BaCl2.2H2O 5 mmol/L são usadas com sucesso. O objetivo deste trabalho foi testar a eficiência do ácido tioglicólico na eliminação da interferência do Fe na dosagem de B do solo com azometina-H, após extrações com soluções ácidas de Mehlich-1 e HCl (50 e 100 mmol/L). Dosagem com azometina-H, com e sem ácido tioglicólico, foram feitas para oito solos de Minas Gerais e dois solos do Mato Grosso do Sul. Foi utilizada como referência, a extração com BaCl2.2H2O 5 mmol/L, com aquecimento em forno de microondas e dosagem com azometina-H; a determinação de B com azometina-H em extratos originados de soluções ácidas sofre forte interferência do Fe. A adição do ácido tioglicólico não remove esta interferência. A coloração do complexo B-azometina-H fica menos estável com a adição do ácido tioglicólico na dosagem do boro.The search for methods to extract boron for evaluation of soil fertility to recommend fertilizer application is important due to the low levels of boron and high levels of iron in most Brazilian soils. Extraction with hot water, the standard method, is a hard work method with operational difficulties. On the other hand, solutions of CaCl2 5 mmol/L and BaCl2.2H2O 5 mmol/L have been used successfully. The objective of this work was to test the efficiency of the thioglycolic acid as a remover of Fe interference in the dosage of B with azomethine-H, after extraction from soil with acid solutions (Mehlich-1, 50 and 100 mmol/L HCl). Dosage with azomethine-H, with and without thioglycolic acid, in soil extracts from eight Minas Gerais State soils and two Mato Grosso do Sul State soils was performed. The reference method was the extraction with 5 mmol/L BaCl2.2H2O in the microwave oven and azomethine-H dosage. The determination of B with azomethine-H in extracts originated from acid extractions undergoes strong interference of Fe. The addition of thioglycolic acid does not remove this interference. The color of the B-azomethine-H complex becomes less stable as thioglycolic acid is added
