Estabilidad de los docentes curriculares de institutos privados reconocidos o adscriptos a la enseñanza oficial : en tiempos de normalidad y en el de la pandemia.
Authors: Seco Francisco 
Published: June 2021

En tiempo de pandemia, el DNU Nº329/2020(B.O.,31/3/2020) del Poder Ejecutivo nacional se dictó en el marco de la emergencia sanitaria por el coronavirus y sus prórrogas decididas por el DNU Nº487/2020 (B.O.,19/5/2020) y el DNU Nº 624/2020 (B.O.,29/7/2020) prohibieron los despidos sin justa causa y por causas económicas y por fuerza mayor por el plazo de 60 días contados a partir de la fecha de su publicación en el Boletín Oficial, desde el 31 de marzo hasta el 29 de mayo de 2020, luego hasta el 28 de julio y más tarde hasta el 26 de setiembre de 2020. Se ha establecido un régimen de estabilidad propia o absolutapara todos los trabajadores privados a los que alcanzan esos DNU, incluidos los docentes privados de cualquier nivel, curriculares o no- pero pro tempore, porque es limitada al plazo de veda. La decisión del Poder Ejecutivo Nacional aparece como constitucional y convencional, adecuada a normas supra legales que él mismo cita y a otras ut supra referidas, como a la jurisprudencia de la CSJN y la CIDH. Pasada la emergencia y la vigencia del DNU, la incógnita está en si se volverá para todos los trabajadores privados en Argentina al sistema de estabilidad relativa impropia o se podrá pasar a una intermedia, como es la que acompaña a los docentes privados mencionados desde 1947, parecida a la del Estatuto de los Trabajadores español para el caso de despido improcedente, o laexcepción del DNU se volverá regla.ABSTRACT: In times of pandemic, DNU No. 329/2020 (BO, 3/31/2020) of the national Executive Power was issued within the framework of the health emergency caused by the coronavirus and its extensions decided by DNU No. 487/2020 (BO, 19 / 5/2020) and DNU No. 624/2020 (BO, 7/29/2020) prohibited dismissals without just cause and for economic reasons and force majeure for a period of 60 days from the date of its publication in the Official Gazette, from March 31to May 29, 2020, then until July 28 and later until September 26, 2020. A regime of own or absolute stability has been established for all private workers to those who reach these DNU, including private teachers of any level, curricular or not - but pro tempore, because it is limited to the closed period. The decision of the National Executive Power appears as constitutional and conventional, adequate to supra-legal norms that it cites itself and to other supra-referred ones, such as the jurisprudence of the CSJN and the IACHR. After the emergency and the validity of the DNU, the question is whether it will return for all private workers in Argentina to the system of improper relative stability or it will be possible to move to an intermediate one, such as the one that accompanies the private teachers mentioned since 1947, similar to that of the Spanish Workers' Statute in the case of unfair dismissal, or the exception of the DNU will become the rule.
Feeding ω-3 PUFA enriched rotifers to Galaxias maculatus (Jenyns, 1842) larvae reared at different salinity conditions: effects on growth parameters, survival and fatty acids profile

Published: June 2021

Despite the well known importance of ω-3 polyunsaturated fatty acids (PUFA) in marine and freshwater fish larvae, there are few studies on how essential fatty acid requirements and composition on whole body can be altered by changes in water salinity. The present study aimed to determine the effect of salinity on ω-3 PUFA requirements, larval growth survival and fatty acid composition of G. maculatus larvae cultured at two different salinities (0 and 15 g∙L-1) for 20 days while fed rotifers containing two different levels of ω-3 PUFA (1.87 and 3.16%). The results denoted a marked difference in ω-3 PUFA requirements and in the pattern of fatty acid deposition in the whole body of larvae reared at different salinities, depending of ω-3 PUFA in diets. Thus, to improve growth and survival larvae of G. maculatus reared at 0 g∙L-1 require higher levels of ω-3 PUFA, principally 18: 3ω-3. Larvae reared at salinities of 15 g∙L-1 require low levels of ω-3 PUFA for optimal survival, especially 18: 3ω-3. Eicosapentaenoic acid and docosahexaenoic acid content in the whole body of larvae was also affected by water salinity.

Authors: Soto Eulogio , Caballero Williams , Quiroga Eduardo 
Published: June 2021

A quantitative study of metazoan meiofauna was carried out in Valparaiso Bay (33°S 71°W) which is affected by seasonal hypoxia in central Chile. The contents of bottom water, dissolved oxygen (BWDO), organic carbon, chloroplast pigments and composition of stable carbon isotope (d13C) in the sediment were used as a measure of the contribution of primary production in the water column, which accumulates in the sediment. Meiofauna abundances in the three sampling stations (80-140 m depth) ranged from 2.218 ± 643 to 1.592 ± 148 ind 10 cm-2. Nine upper metazoan meiofauna groups were recorded, with nematodes as the dominant group, contributing with more than 95% of total abundances. The abundance vertical distribution was concentrated in the first layers of sediment in most groups except Acari and nauplii larvae. Canonical correspondence analysis revealed significant correlations (P < 0.05) between the meiofauna abundance and organic content, depth and redox potential from sediments. These results represent a first approach to understanding the ecology of meiofaunal assemblages in the Valparaiso Bay and may be useful as a baseline for future comparisons and descriptions of the ENSO (El Niño Southern Oscillation) and seasonal variations of these unknown benthic communities.

The aim of this study was to evaluate the effect of probiotic Bacillus amyloliquefaciens on the growth performance, blood profile and intestinal morphometry in Nile tilapia (Oreochromis niloticus) reared in cages. 936 Nile tilapias were distributed in 12 cages (1.5 m3). Fish were fed for 90 days on basal diets containing 0 (control); 1×106 CFU g-1; 5×106CFU g-1; and 1×107CFU g-1 of the probiotic. The results showed no significant difference on performance and proximal composition of fish. Blood glucose and hemoglobin were lower in 1×107 CFU g-1 group, suggesting improves of the homeostatic state of the fish. Other hematimetric indices did not differ between groups. It was observed significant increase of villi height and in the number of goblet cells of the intestine in fish supplemented 5×106 CFU g-1 and 1×107 CFU g-1 of food suggesting that fish improved the digestion and absorption of nutrients. However, more studies are needed to determine the efficacy of this probiotic in field conditions in Nile tilapia.
Inhabiting fauna in holdfasts of Lessonia nigrescens complex. Is it an indicator of ecological integrity in exploited kelp beds in northern Chile?
Authors: Vega Reyes J.M. Alonso 
Published: June 2021

Lessonia nigrescens complex holdfasts habitats are home to a wide diversity of invertebrates. The holdfasts associated fauna is sensitive to the kelp fishery in northern Chile because one of the management recommendation is to harvest the whole plant. Considering the above, and the ecological role play by brown algae as foundation species, this study proposes the use of fauna inhabiting the holdfasts as an ecological indicator to monitor the integrity of exploited kelp beds. To accomplish this objective, the morphology of plants and holdfasts was evaluated together with the composition, abundance and community structure associated in three types of resource conservation strategies based on fishery management spatially explicit: open access areas and management areas (to harvest), and marine protected areas (with no harvest), in Atacama and Coquimbo (26-32°S). The results show that high harvest pressure on exploited kelp beds transforms the plant morphology and holdfast, altering the colonization process and species aggregation predicted for these biogenic habitats modifying the expected biodiversity. Thus, associated fauna in open access areas has lower species richness, abundance and biodiversity of organisms than their counterparts in management areas or marine protected areas. Moreover, the structure of the holdfast associated communities, are more variables in open access areas. The results suggest that holdfasts are representative micro-ecosystems of the intertidal environment, and can be used as sampling replicable and comparable units to monitor exploited kelp beds integrity in fisheries open access areas. This ecological indicator is easy to evaluate and disseminate among users of the kelp productive chain.

Published: June 2021

The high density of vehicles that run to and fro University campus to town has become of great concern for assessment of health status of the ambient air around the Universities motor parks. Moreover, some of the University’s parks are unpaved while the paved ones are old and unmaintained. Dust fall samples in parks of Universities of Ilorin, Ibadan and Kwara State University were collected for five months spanning from 1st November 2014 to 31st March, 2015 using open bucket sampler based on ASTM D 1739 of 1998 (2010). A 0.1 g of dust sample was digested with 20 ml of HNO3, HClO4 and HF in ratio of (3:2:1) respectively and heavy metals (Mn, Cu, Zn, Cd, Pb, and Ni) were analysed using atomic absorption spectrophotometer (Buck Scientific model 210 VGP). Results of heavy metal concentrations showed decrease in the following order: 1479.75, 1255.68, 241.50, 128.00, 85.25, and 9.63 mg/kg for Mn, Zn, Pb, Ni, Cu and Cd respectively for University of Ibadan. The decreased in concentrations of heavy metals obtained for University of Ilorin motor park dust-fall were found to be 1145.75, 797.75, 219.63, 133.51, 58.25 and 23.13 mg/kg for Mn, Zn, Pb, Ni, Cu and Cd respectively. For Kwara State University, decrease in the following order: 778.5, 323.88, 259.38, 101.38, 34.38, and 4.63 mg/kg for Mn, Zn, Pb, Ni, Cu and Cd respectively were obtained. Generally for the three sites used, the heavy metal concentrations decreased in the following order: Mn>Zn>Pb>Ni>Cu>Cd. This implies that dust-fall in the parks are heavily loaded with some heavy metals that are of concentrations above Romania standard threshold limit for Cd and Pb while concentration values obtained for Ni are higher than US- EPA values (75 mg/kg). The regulatory agent or management should ensure that the roads are paved and there should be intermittent wetting of the roads with water.Keywords: Dust Fall; Heavy Metals; University Motor Parks

Effect of plant growth regulators and nitrogenous compounds on seed germination of pepper (Capsicum frutescens L)
Authors: Eremrena P.O. , Mensah S.I. 
Published: June 2021

The seed germination of Capsicum frutescens L. was investigated through various methods, namely, washing and air dry storage treatments, applications of gibberelic acid (GA3), Kinetin, potassium nitrite (KNO2) and potassium nitrate (KNO3) to improve germination of seeds in view of poor germination reported. The seeds were subjected to the following treatments namely washing to remove the slimy coverings; air-drying at various time-intervals; incubated in different concentrations of GA3, Kinetin, KNO2 and KNO3. The treatments were subjected to light or dark germinations at 300C and radicle emergence scored after 15days. The various results showed that washing treatment, and light germination had a significant effect on the germination of Capsicum frutescens seeds. For air-drying treatment, germination increased from 0-48hrs and decreased after 72hrs, 48hrs air-drying duration gave the highest percentage germination. Application of GA3, kinetin, KNO2 and KNO3 in low concentrations promoted the germination of freshly harvested Capsicum frutescens seeds. Generally the KNO2 and KNO3 gave the best germination results. The findings of this study have significant implications in the commercial production of Capsicum frutescens in view of its economic and medicinal importance.Keywords: Growth regulators, Nitrogenous compounds, Capsicum frutescens
Excellency of Converse Scalping Forehead Flap for Reconstruction of External Nasal Soft-Tissue Defects
Authors: Chaudhuri Gaurab Ranjan 
Published: June 2021

Introduction

Reconstruction of external nasal defects poses a challenge for the plastic surgeons. The scalping forehead flap, first described by Converse in 1942 is a versatile technique for subtotal and total external nasal reconstruction. The flap is extremely reliable with robust vascularity and provides excellent colour and texture match for the external nose with minimal donor-site morbidity.

Materials and Methods
In this series, eleven patients with external nasal soft-tissue defects (post traumatic and post excisional) were reconstructed with scalping forehead flap; among them four presented with congenital naevus, three with post-traumatic external nasal defect, two presented with basal cell carcinoma, and two with arterio-venous malformation. The age of the patients ranged between 24 and 67 years; eight male and three female patients were included in this study. Among them three had comorbidities like diabetes mellitus and/ hypertension.
Results
All the flaps survived nicely. I didn’t face any complication in any of my patients. The external nasal defects were reconstructed with scalping forehead flap in two stages with an interval of three weeks in between.
Conclusion
The Converse scalping forehead flap is an excellent option in the armamentarium of plastic surgeons for subtotal and total nasal reconstruction because of its reliability, vascularity, and simplicity even in the era of microvascular free tissue transfer.
SERVIÇOS ECOSSISTÊMICOS DE ÁGUAS LÓTICAS E OS POSSIBILISMOS AMBIENTAIS PARA O USO SOCIAL DOS RECURSOS HÍDRICOS. SOB A LEITURA DA ETNOECODESIGN
Authors: Sena Paulo Sergio de 
Published: June 2021

O saber ambiental humano que se estabelece com a relação entre os grupos sociais culturais com os ecossistemas é capaz de transformar os recursos naturais em produtos e serviços possíveis de serem utilizados para a subsistência cotidiana e a manutenção das culturas das diversas sociedades, com bens materiais e imateriais. Os ambientes hídricos lóticos possibilitam serviços e produtos ambientais: consumo de água, microclima local, alimentos, nutrientes para agricultura, mobilidade, energia, paisagem (estético) e lazer que necessitam ser classificados quanto ao tipo de serviço e produto - regulação, suporte, produção e cultural para que se possa pensar numa sustentabilidade possível que responda as questões de expressão cultura local, conectividade entre os humanos e os ecossistemas e os possíveis agravos que as culturas podem gerar em ecossistemas. O objetivo é testar uma ferramenta de etnoecodesign para avaliar os serviços ambientais. Quando ao Material e Métodos recorreu-se à metodologia para Ecodesign de Back (1983) que contempla aspectos do desenvolvimento sustentável como sistematização para leitura de sistemas e subsistemas. Este trabalho mostrou que a conectividade humano e ecossistema ficou prejudicado pela intensa expressão cultural e seus agravos ao ambiente lótico, contribuindo para criar não lugares antropológicos.

Este texto problematiza o processo de incorporação e desenvolvimento da Agroecologia em áreas de reforma agrária proposto pelo principal movimento socioterritorial do campo no Brasil, o Movimento dos Trabalhadores Rurais Sem Terra (MST). Para tanto, analisa as práticas agroecológicas no acampamento Herdeiros da Terra de 1º de Maio, localizado nos municípios de Rio Bonito do Iguaçu e Nova Laranjeiras, no Paraná. Por meio de pesquisa participante, realização de entrevistas e análise de documentos, o artigo detalha como a Agroecologia foi sendo construída em meio ao processo de reorganização territorial do acampamento. O texto examina uma etapa fundamental para a consolidação da Agroecologia nas áreas de reforma agrária, dado que as experiências do período da ocupação orientam os sistemas produtivos desenvolvidos após a conquista da terra. Apesar das dificuldades para sua territorialização, a pesquisa identificou a permanência da Agroecologia ao longo dos cinco anos do acampamento e um potencial para a consolidação das práticas agroecológicas, considerando-se os recursos territoriais e o interesse dos sujeitos, desde que a área seja destinada para a reforma agrária.Como citar este artigo: MELLO, Juliana Cristina de; FINATTO, Roberto Antônio; EDUARDO, Márcio Freitas.

A juventude camponesa constituiu uma agenda de formação política, socioeconômica e cultural, com mobilizações de luta pelo acesso à terra, ao trabalho e à educação pública de qualidade, no campo e na cidade. O objetivo deste artigo é analisar o protagonismo da juventude sem-terra, no Ceará, no processo de democratização da universidade pública, a partir da prática política nos cursos de formação sobre a realidade brasileira para jovens do campo (2001 a 2019). Em tempos de ameaças aos movimentos socioterritoriais e à educação pública brasileira, o resgate da memória, estimulado ao longo dos períodos de formação, passa a ser um caminho de fortalecimento de outras leituras e projetos de desenvolvimento no país. A metodologia foi baseada na leitura de artigos referentes à temática, na observação participante, em entrevistas diretas e na coleta de matérias escritas em revistas, jornais e mídias sociais. O protagonismo da juventude tem-se configurado na constituição de uma agenda própria, desenvolvida por diferentes coletivos e eventos, como marchas, ocupações e jornadas de luta em defesa da terra e do território, da reforma agrária popular, da educação pública de qualidade e de um projeto de vida a favor da diversidade social no campo e na cidade.Como citar este artigo: OLIVEIRA, Alexandra Maria de.

Carcinoma neuroendocrino primario de la glándula mamaria, reporte de caso y revisión de la literatura.
Authors: Bonilla González Carlos Eduardo , Russi Noguera July Andrea , Gómez Carolina , Lasso Miller 
Published: June 2021

El carcinoma neuroendocrino primario de la glándula mamaria pertenece al grupo de tumores neuroendocrinos de la mama. Dada su baja incidencia, la mayor parte de la literatura se basa en series de casos, por lo tanto, su comportamiento biológico y pronóstico muestra resultados divergentes. Su característica principal es el hallazgo histopatológico de la expresión dual en el tumor de marcadores epiteliales y neuroendocrinos en mayor o menor grado que, en algunos casos, inclusive pueden coexistir en la misma célula. Se presenta el caso de una mujer con diagnóstico de carcinoma neuroendocrino de la mama, con una revisión de la literatura sobre las características clínicas y opciones de manejo.
