Una asociación de trilobites del Furongiano tardío del sector este de la Cordillera Oriental (Formación Santa Rosita; Jujuy, Argentina) y su significado bioestratigráfico

La Zona de trilobites de Parabolina frequens argentina está ampliamente representada en el Furongiano superior del noroeste argentino. En este trabajo se describe una asociación fosilífera del tramo inferior de la Formación Santa Rosita aflorante en la Quebrada de Abra Blanca, Provincia de Jujuy. Parabolina frequens argentina (Kayser) y Parabolinella coelatifrons Harrington & Leanza fueron previamente citados en otras localidades de la biozona, mientras que Lotagnostus hedini (Troedsson) es descripto aquí por primera vez para Sudamérica. Este último taxón aporta datos precisos sobre la edad de la Zona de P. frequens argentina en el sector este de la Cordillera Oriental, en donde aún no se han hallado rocas portadoras de faunas de conodontes. Lotagnostus hedini posee un rango bioestratigráfico corto, limitado al Furongiano más tardío de China (Xinjiang, Zona de Bulbolenus; oeste de Zhejiang, Zona de Lotagnostus hedini), Kazakstán (Zona de Euloma limitaris-Taoyuania) y ?Canadá (oeste de Newfoundland, Fauna de Phylacterus saylesi). En China y Kazakstán se registra asociado a, o unos pocos metros por debajo de la primera aparición del conodonte Cordylodus proavus, lo cual incrementa el potencial para realizar correlaciones globales.The trilobite Parabolina frequens argentina Zone is widely represented in the upper Furongian of northwestern Argentina. A fossil assemblage from the lower Santa Rosita Formation at Quebrada de Abra Blanca, Jujuy Province, is described herein. Parabolina frequens argentina (Kayser) and Parabolinella coelatifrons Harrington & Leanza have previously been reported from other localities of the biozone, whereas Lotagnostus hedini (Troedsson) is here described from South America for the first time. The latter provides high resolution data on the age of the P. frequens argentina Zone in the eastern Cordillera Oriental, where conodont-bearing strata have not been found yet. L. hedini exhibits a short biostratigraphic range, restricted to the latest Furongian of China (Xinjiang, Bulbolenus Zone; western Zhejiang, Lotagnostus hedini Zone), Kazakhstan (Euloma limitarisTaoyuania Zone) and ?Canada (western Newfoundland, Phylacterus saylesi Fauna). In China and Kazakhstan, it occurs in association with, or a few meters below, the first appearance of the conodont Cordylodus proavus; a fact that increases the potential for global correlation.Facultad de Ciencias Naturales y Muse

Switchgrass and Giant Reed Energy Potential when Cultivated in Heavy Metals Contaminated Soils

Funding Information: This work was supported by the Mechanical Engineering and Resource Sustainability Center—MEtRICs, which is financed by national funds from Fundação para a Ciência e Tecnologia, FCT/MCTES (UIDB/04077/2020 and UIDP/04077/2020). Publisher Copyright: © 2022 by the authors.The cultivation of energy crops on degraded soils contributes to reduce the risks associated with land use change, and the biomass may represent an additional revenue as a feedstock for bioenergy. Switchgrass and giant reed were tested under 300 and 600 mg Cr kg−1, 110 and 220 mg Ni kg−1, and 4 and 8 mg Cd kg−1 contaminated soils, in a two year pot experiment. Switchgrass yields (average aerial 330 g.m−2 and below ground 430 g.m−2), after the second year harvest, were not affected by Cd contamination and 110 mg Ni kg−1, but 220 mg Ni kg−1 significantly affected the yields (55–60% reduction). A total plant loss was observed in Cr-contaminated pots. Giant reed aboveground yields (control: 410 g.m−2), in the second year harvest, were significantly affected by all metals and levels of contamination (30–70% reduction), except in 110 mg Ni kg−1 pots. The belowground biomass yields (average 1600 g.m−2) were not affected by the tested metals. Contamination did not affect the high heating value (HHV) of switchgrass (average 18.4 MJ.kg−1) and giant reed aerial fractions (average 18.9 MJ.kg−1, stems, and 18.1 MJ.kg−1, leaves), harvested in the second year, indicating that the biomass can be exploited for bioenergy.publishersversionpublishe

Ensayo comparativo de rendimiento de maíz - Campaña 2023

La elección de un cultivar considera un conjunto de características como el ciclo, la velocidad de secado de grano, el comportamiento sanitario, la resistencia al quebrado y al vuelco de la caña, los rendimientos y relación precio/rentabilidad. Cada uno de estos aspectos puede tener una importancia relativa distinta según las características de producción de la empresa agropecuaria. El objetivo de este trabajo es la identificación de híbridos comerciales de maíz de genética moderna, estables y con alto potencial de rendimiento que ayude a asesores y productores en la elección de los materiales, en el área de influencia de la localidad de San Antonio de Areco, en el norte de la provincia de Buenos Aires.EEA PergaminoFil: Mousegne, Fernando.

Evaluation of comprehensive care for older adults in primary care services

OBJECTIVE: To evaluate the performance of comprehensive care for older adults in primary care services in the Brazilian Unified Health System in the state of Sao Paulo, Brazil. METHODS: A total of 157 primary care services from five health regions in midwestern Sao Paulo responded, from October to December 2014, the pre-validated 2014 questionnaire for primary care services assessment and monitoring. We selected 155 questions, based on national policies and guidelines on this theme. The responses indicate the service performance in older adults' care, clustered into three areas of analysis: health care for active and healthy aging (45 indicators, d1), chronic noncommunicable diseases care (89 indicators, d2), and support network in aging care (21 indicators, d3). Performance was measured by the sum of positive (value 1) or negative (value 0) responses for each indicator. Services were clustered according to k-means of the performance scores of each domain. After weighting the domains (Z tests), we estimated the associations between the scores of each domain and independent management variables (typology, planning and evaluation of services), with simple and multiple linear regression. RESULTS: Chronic noncommunicable diseases care (d2) showed, for all clusters, better average performance (55.7) than domains d1 (35.4) and d3 (39.2). Service performance in the general area of planning and evaluation associates with the performance of older adults' care. CONCLUSIONS: The evaluated services had incipient implementation of comprehensive care for older adults. The evaluation framework can contribute to processes to improve the quality of primary health care. OBJETIVO: Avaliar o desempenho da atenção integral ao idoso em serviços de atenção primária do Sistema Único de Saúde no estado de São Paulo, Brasil. MÉTODOS: Um total de 157 serviços de atenção primária de cinco regiões de saúde do centro-oeste paulista respondeu, de outubro a dezembro de 2014, o instrumento pré-validado Questionário de Avaliação e Monitoramento de Serviços de Atenção Básica 2014. Foram selecionadas 155 questões, com base nas políticas e diretrizes nacionais sobre essa temática. As respostas indicam o desempenho do serviço na atenção ao idoso, agrupadas em três domínios de análise: atenção à saúde para o envelhecimento ativo e saudável (45 indicadores, d1), atenção às doenças crônicas não transmissíveis (89 indicadores, d2) e rede de apoio na atenção ao envelhecimento (21 indicadores, d3). A medida de desempenho foi a soma de respostas positivas (valor 1) ou negativas (valor 0) para cada indicador. Os serviços foram agrupados segundo k-médias dos escores de desempenho de cada um dos domínios. Após a ponderação dos domínios (testes Z), foram estimadas as associações entre os escores de cada domínio e variáveis independentes de gestão (tipologia, planejamento e avaliação dos serviços), por meio de regressão linear simples e múltipla. RESULTADOS: A atenção às doenças crônicas não transmissíveis (d2) mostrou, para todos os agrupamentos, melhor desempenho médio (55,7) do que os domínios d1 (35,4) e d3 (39,2). O desempenho do serviço na área geral de planejamento e avaliação esteve associado ao desempenho da atenção ao idoso. CONCLUSÕES: Os serviços avaliados apresentaram implementação incipiente da atenção integral ao idoso. O quadro avaliativo pode contribuir para processos de melhoria da qualidade da atenção primária à saúde.publishersversionpublishe
