Rosalía de Castro, sombra que se fai teoría

A figura auroral de Rosalía de Castro autorizou a aparición de novas poetas a finais do século XX mais, paradoxalmente, a partir da publicación dos seus libros fundacionais non xurdiu unha lexión de autoras que desde Cantares gallegos (1863) e Follas novas (1880) escribisen incesantemente a nación, ou simplemente, escribisen incesantemente en galego e tivesen por iso un recoñecemento canónico. Sen dúbida a intervención do patriarcadogaleguista provocou esa interrupción, que se entende mellor cando se teñenen conta os condicionantes socioliterarios que coutaban as mulleres escritoras (González Fernández, 2005: 15-19). Porque a finais do século XIX, e malia excepcións rechamantes, o pensamento hexemónicoconsideraba que as literatas eran unhas sabias ridículas, tal como sesancionara desde o coñecido capítulo V do Émile, ou l’Education (1762) deJean Jacques Rousseau en diante, aínda que houbese, por suposto, vocesdisidentes entre os seus contemporáneos, como Benito Jerónimo Feijoo noseu moi lido discurso XVI, Defensa de las mujeres, do seu Teatro crítico universal(1726). Nese sentido depreciativo do termo debe lerse o coñecido artigo deRosalía de Castro, Las literatas. Carta a Eduarda (1865). Por outra banda, noemerxente discurso nacionalista que vai do XIX ao primeiro terzo do XXopérase unha corrección misóxina que afecta á concepción sexuada danación. Se Murguía seguira a Renan na súa defensa do carácter esencialmente feminino dos pobos celtas, unha idea moi espallada naquela...

Low environmental impact bleaching sequences for attaining high brightness level with eucalyptus SPP pulp

The alternatives used for minimizing the usage of chlorine dioxide in bleaching sequences included a hot acid hydrolysis (Ahot) stage, the use of hot chlorine dioxide (Dhot) and ozone stages at medium consistency and high consistency (Zmc and Zhc), in addition to stages with atmospheric hydrogen peroxide (P) and pressurized hydrogen peroxide (PO). The results were interpreted based on the cost of the chemical products, bleaching process yields and on minimizing the environmental impact of the bleaching process. In spite of some process restrictions, high ISO brightness levels were kept around 90 % brightness. Additionally, the inclusion of stages like acid hydrolysis, pressurized peroxide and ozone in the bleaching sequences provided an increase in operating flexibility, aimed at reducing environmental impact (ECF Light). The Dhot(EOP)D(PO) sequence presented lower operating cost for ISO brightness above 92 %. However, this kind of sequence was not allowed for closing the wastewater circuit, even partially. For ISO brightness level around 91%, the AhotZhcDP sequence presented a lower operating cost than the others

Deposição de agrotóxicos pulverizados na cultura da maçã

O objetivo deste trabalho foi avaliar a distribuição da deposição de agrotóxicos pulverizados em duas cultivares de maçã (Malus domestica Borkh). Uma calda com traçador Rodamina B foi pulverizada, com equipamento do tipo carreta com cortina de ar, com dois tipos de calibrações. Em uma calibração foram utilizados bicos cones JA-1, JA-2 e JA-3 e na outra, bicos leque AVI 110 ISO-04 e bicos JA-1. Não houve diferenças entre as calibrações, mas a deposição nas plantas foi decrescente da região apical para a basal. Nas calibrações testadas, 25% do traçador aplicado perdeu-se no solo.

El boom de la calidad en las empresas españolas

In this article we analyze the impact of the implementation on Quality Management Systems (QMS) in the Spanish industry. In order to do it, we study the implementation of the famous standard ISO 9000 and the EFQM model in Spain compared with its impact in the rest of the UE-25. In spite of analyzing the motivations and the results obtained after the implementation of these Quality Management Systems, we present the results of a Delphi?s national study

La consultoría en España ¿consulta o inculcación de principios?

The ISO 9000-2000 standard provides eight quality management principles. They may be used by senior managers as a framework to guide their organizations towards improved performance. The article analyzes the way the specialized consultants implementing the norm enable their costumers to assume the principles. It had been found that the better a consultant transmits the spirit of the norm, the better for himself and for their clients as well. In fact, the consultancy will get a higher recommendation degree; ant the organization will get more benefits

Los estándares internacionales de sistemas de gestión : pasado, presente y futuro

En este artículo se analiza la fuerte incidencia que en los últimos años ha tenido a nivel internacional la difusión de diversos estándares internacionales de sistemas de gestión de empresas. Se analiza la génesis y difusión de las principales normas internacionales de gestión – la familia de normas ISO 9000- e ISO 14000-, subrayándose la especial repercusión de estos estándares en la Unión Europea (UE) y en España, para a continuación analizar cuáles son los nuevos ámbitos de la gestión empresarial sobre los que se han promulgado, o se ha planificado promulgar, este tipo de estándares. Asimismo, se analizan las fortalezas y debilidades de la extensión de este modelo de normalización, y se reflexiona, por último, acerca de evolución futura

Characterization of cerebral glucose dynamics in vivo with a four-state conformational model of transport at the blood-brain barrier.

Determination of brain glucose transport kinetics in vivo at steady-state typically does not allow distinguishing apparent maximum transport rate (T(max)) from cerebral consumption rate. Using a four-state conformational model of glucose transport, we show that simultaneous dynamic measurement of brain and plasma glucose concentrations provide enough information for independent and reliable determination of the two rates. In addition, although dynamic glucose homeostasis can be described with a reversible Michaelis-Menten model, which is implicit to the large iso-inhibition constant (K(ii)) relative to physiological brain glucose content, we found that the apparent affinity constant (K(t)) was better determined with the four-state conformational model of glucose transport than with any of the other models tested. Furthermore, we confirmed the utility of the present method to determine glucose transport and consumption by analysing the modulation of both glucose transport and consumption by anaesthesia conditions that modify cerebral activity. In particular, deep thiopental anaesthesia caused a significant reduction of both T(max) and cerebral metabolic rate for glucose consumption. In conclusion, dynamic measurement of brain glucose in vivo in function of plasma glucose allows robust determination of both glucose uptake and consumption kinetics.

Methodological adaptation for nematodes extration in forest soils of the southern Mata Atlântica

The objective of this work was to clarify whether the method to extract nematodes from European soils is suitable for forest soils and litter in the eastern of Paraná state, Brazil, and whether nematode abundance differs between sites with different ecosystems and levels of human interference. The study sites were situated in the coastal area of the Serra do Mar, near the town of Antonina, in Eastern Paraná, Brazil. Cobb's sieving and decanting method was more appropriate than ISO method, since extraction efficiency was higher and intra-sample variability was significantly lower. In order to achieve an extraction efficiency higher than 90%, Cobb's method was modified. For the extraction of nematodes from litter, the Baermann funnel, with an extraction time of 48 hours, yielded an extraction efficiency higher than 90%. Nematode abundance in litter was higher than in soil. The mean number of individuals extracted from the litter increased with the age stage of the forest sites sampled, and there was no difference in the number of individuals in the soil of the four forest sites. Mean nematode abundance in soil in banana plantations was about twice as high compared to the banana-palmito mixed stands and to the forest sites.
