A soil quality index to evaluate the vermicompost amendments effects on soil properites

502-510The aims of this work were 1) to evaluate the changes in soil properties with the application of different amounts of vermicompost (10 and 20 Mg·ha–1), and 2) to construct a soil quality index that allows the evaluation of changes in the most sensitive soil parameters. The study was carried out in a cattle field of General Alvear, Buenos Aires, Argentina. Vermicompost application showed a positive effect on most of the chemical and biological soil properties evaluated, especially with the higher dose (20 Mg·ha–1). There were slight but significant increases in electrical conductivity and soil pH with the higher dose of vermicompost. Physical soil properties were not affected by the vermicompost amend-ment. The SQI showed a significant increase of soil quality with the vermicompost dose of 20 Mg·ha–1, especially by enhancing the biochemical and biological properties

Na elucidação do objeto de estudo optou-se pelo método de abordagem qualitativos e tipos de pesquisa bibliográfica, documental e exploratória como resultados podemos inferir que a crise antecede a Pandemia, mas é nela que vai se intensificar, precarizando as condições de trabalho e atuação profissional deixando-a mercê das emergências

Correlates of Smoking Cessation Among Filipino Immigrant Men

A survey on tobacco use among 318 Filipino immigrant men aged 40–75 years was conducted in Los Angeles, California. Those who reported more English language use with their family, friends and neighbors (OR = 1.31) and who lived in households with complete smoking prohibition (OR = 3.82) were more likely to be successful in quitting smoking. Those who endorsed more positive beliefs on physical and social consequences of smoking (OR = 0.69) and who had mostly smoking friends (OR = 0.37) were less likely to be successful in quitting smoking. Our findings suggest that prohibiting smoking in households, creating social networks of non-smokers, and education or counseling are important components of a smoking cessation intervention for Filipino immigrant men

Participative planning: Urban-rural territories in San Juan Province

En los últimos años se registra en Argentina una expansión de las ciudades hacia territorios rurales acentuando procesos de segregación socio-espacial. En la provincia de San Juan, la implementación del Programa Lote Hogar, ha propiciado urbanizaciones en territorios de interfaz urbano-rural en el Área Metropolitana de la provincia. En este contexto, se advierte que las urbanizaciones no han incorporado características particulares de la población, ni las infraestructuras necesarias para generar conexiones con la ciudad, así como tampoco se proyectan espacios suficientes que coadyuven al fortalecimiento de redes sociales al interior del barrio. El presente trabajo expone los resultados de un proyecto de desarrollo tecnológico y social que tiene como objetivo la elaboración de instrumentos de planificación participativa para la intervención de barrios construidos en la interfaz urbano-rural. Para ello, se selecciona como caso de estudio el Barrio Lote Hogar 24. Se sostiene que a través del diseño y aplicación de instrumentos de planificación que incorporen a los actores locales, es posible revertir procesos de segregación socio-espacial. Finalmente, se presentan recomendaciones a las políticas habitacionales haciendo foco en las particularidades que presentan los barrios en territorios de interfaz urbano-rural, con vistas a su vinculación con la ciudad y la cohesión al interior del barrio.The present work let us know the result of a project of technological and social development which has as an aim the elaboration of tools for participative planning in the intervention of neighborhoods built in the urban-rural interface. In recent years it has been detected the expansion of cities towards rural territories producing increas-ingly social and spatial segregation processes. In San Juan province, the implementation of Lote Hogar Program has led to urbanizations in urban-rural interface territories of the Metropolitan Area of the province. These urbanizations neither have incorporated particular characteristics of their population, (as it is the case of Lote Hogar 24) or the necessary infrastructure to generate connections with the city, in fact, there have not been projected enough spaces in these places to contribute to strengthening social networks towards the inside of the district. It is sustained that through the design and application of planning tools which incorporates local actors, it is possible to get a reverse in social-spatial segregation processes. Therefore, recommendations as regards housing policies are put forward, focusing on these particularities of neighborhoods in urban-rural interface territories, with the aim of their further interrelation with the city and their cohesion within the neighborhood.Fil: Romero, Mirta Beatriz.

Environmental selection pressures related to iron utilization are involved in the loss of the Flavodoxin Gene from the plant genome

Oxidative stress and iron limitation represent the grim side of life in an oxygen-rich atmosphere. The versatile electron transfer shuttle ferredoxin,aniron-sulfurprotein,isparticularlysensitivetothesehardships,anditsdownregulationunderadverseconditionsseverely compromises survival of phototrophs. Replacement of ferredoxin by a stress-resistant isofunctional carrier, flavin-containing flavodoxin, is a widespread strategy employed by photosynthetic microorganisms to overcome environmental adversities. The flavodoxin gene was lostin the course ofplantevolution, but its reintroduction in transgenicplants confers increased tolerance to environmental stress and iron starvation, raising the question as to whya genetic asset with obvious adaptive value was not kept by natural selection. Phylogenetic analyses reveal that the evolutionary history of flavodoxin is intricate, with several horizontal gene transfer events between distant organisms, including Eukarya, Bacteria, and Archaea. The flavodoxin gene is unevenly distributed in most algal lineages, with flavodoxin-containing species being overrepresented in iron-limited regions and scarce or absent in iron-rich environments. Evaluation of cyanobacterial genomic and metagenomic data yielded essentially the same results, indicating that there was little selection pressure to retain flavodoxin in iron-rich coastal/freshwater phototrophs. Our results show a highly dynamic evolution pattern of flavodoxin tightly connected to the bioavailability of iron. Evidence presented here also indicates that the high concentration of iron in coastal and freshwater habitats may have facilitated the loss of flavodoxin in the freshwater ancestor of modern plants during the transition of photosynthetic organisms from the open oceans to the firm land.Fil: Pierella Karlusich, Juan José.

Atrazine degradation by wild filamentous fungi

Bioremediation is a promising technology for the treatment of polluted areas due to its minor cost;moreover, indigenous fungi had not been already applied to detoxify contaminated habitats. The kinetic of atrazine degradation by Gliocladium roseum, Mucor alternans and Pycnidiophora dispersa were assessed in soluble and soil sorbed herbicide with different organic matter content. Their half-saturation constants, Km, expressed the affinity for the substrate, being 12.5, 3.8 and 2.7 μg/ml for G. roseum, M. alternans and P. dispersa. Moreover, Vmax, uptake rate/ biomass, assumed by the asymptotes of each fungal curves were 43.5-41.0, 37.5-35.0 and 26.5-24.5 μg Atz/min-1. mg for G. roseum, M. alternans and P. dispersa, respectivelly. The 65-75% was in soluble phase, that was preferentially degraded by fungi. Our results showed that the atrazine transformation were consistent with those in pure cultures, suggesting that the parameters derived from in-vitro studies may be useful to predict the herbicide detoxification in polluted sediments. Fungal kinetic allowed us to predict the atrazine degradation in natural contaminated habitats and was in relation to the herbicide levels especially in soil solutions.Fil: Romero, Maria Cristina.
