Abstract: objective: to evaluate physical performance on the six-minute walk test (6mwt) in patients with non-cystic fibrosis bronchiectasis and to investigate its relationship with quality of life (qol). to identify predictors of exercise performance, we also investigated whether six-minute walk distance (6mwd) is associated with clinical and spirometric findings. methods: this was a cross-sectional study involving patients with non-cystic fibrosis bronchiectasis (age, > 18 years), with at least one respiratory symptom for > 2 years and an fev1 < 70% of predicted. patients underwent clinical evaluation, pulmonary function tests, the 6mwt, and qol assessment with the medical outcomes study 36-item short-form health survey (sf-36). results: we included 70 patients (48 females). mean age was 54.5 ± 17.7 years, and mean fev1 was 44.9 ± 14.5% of predicted. the patients were divided into two groups: 6mwd-low (6mwd below the predicted lower limit; n = 23); and 6mwd-norm (normal 6mwd; n = 47). the following variables were significantly lower in the 6mwd-low group than in the 6mwd-norm group: age; age at diagnosis of bronchiectasis; proportion of former smokers; body mass index (bmi); fev1% of predicted; and mep% of predicted. there were no significant differences in the sf-36 scores between the groups. in the logistic regression model, lower age and lower bmi were significantly associated with lower 6mwd. conclusions: in this sample, there was a high proportion of patients who presented a lower than expected 6mwd. although 6mwd was not related to qol, it was associated with age and bmi.

Abstract: La mancha en red de la cebada (Hordeum vulgare) es la enfermedad más importante de este cultivo en la Argentina. El tratamiento químico de semillas es una medida importante de control para impedir la introducción y dispersión de Drechslera teres. Los objetivos de este trabajo fueron 1) evaluar la fungitoxicidad específica in vitro de diferentes dosis del fungicida iprodione y sus mezclas con thiram y triticonazole y compararlos con los fungicidas más utilizados (flutriafol y tebuconazole), y 2) valorar a campo, el mejor tratamiento obtenido in vitro. Los resultados mostraron que los fungicidas actualmente en uso en Argentina fueron menos eficientes en el control de D. teres que el iprodione sólo (50 g i.a.) o en mezcla con triticonazole y thiram. En parcelas apareadas con iprodione + triticonazole versus testigo se evaluaron el número de focos de infección primaria, incidencia, severidad y el rendimiento agronómico. Las diferencias entre tratamientos fueron significativas indicando la importancia epidemiológica de la semilla infectada. Se concluye que la mezcla de iprodione + triticonazole fue eficiente en el control de D. teres en semilla, in vitro y a campo, permitiendo disminuir significativamente la epidemia de la mancha en red.
New Actors on Stage: Analysis of the Emergent Forms of Collective Action in the European Context  [PDF]
Dora Fonseca
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.21005
Abstract: In this article our focus will be on civil society’s responses triggered by the imposition of the societies of austerity. The analysis will be centred on an emerging collective actor, the indignados, and on the conditions that fostered its formation and processes involved in the construction of its identity. To accomplish this task, we retrieved Ernesto Laclau’s political logic of populism and the concept of political developed by Chantal Mouffe and applied them to the formation of the indignados’ identity. This process is conceived in terms of the construction of antagonistic frontiers which divide the social into two opposing fields. This conception allows us to develop an analysis based on the notion of social conflict, as well as a reflection on the potentialities embodied by this new social actor, despite their presentation by the dominant discourse as utopic and therefore impossible. In this proposal, it is our aim to provide a better understanding of what is at stake when we talk about the indignados and a clearer perception of the political dimension of both struggle and resistance.
Duplicación apendicular Appendicular duplication

Abstract: El apéndice cecal es un órgano pródigamente estudiado, debido a la gran frecuencia con que se producen inflamaciones agudas en él, no obstante, son menos conocidas las anomalías congénitas que resultan en una duplicación apendicular, por ser esta una entidad rara. Se presenta un caso de una paciente que se interviene quirúrgicamente por una apendicitis aguda, en la cual se encontró otro apéndice cecal. Se realiza discusión y revisión del tema. Cecal appendix is much studied organ due to the high frequency of its acute inflammations, however, the congenital anomalies are less associated resulting in a appendicular duplication because of it is a rare entity. This is the case of a female patient operated on due to acute appendicitis founding another cecal appendix.

Abstract: regression logistic techniques were used to study the environmental variables associated with fumonisin content in maize grain. the dependent variable consisted of 29 values of fumonisins b1 and b2 (fb1 and fb2) from samples of susceptible hybrid sowed in several sites of the pampas region from 2006/07 to 2008/09. meteorological variables were recorded in relation to the silking stage. the np2 variable (number of periods of two days with simultaneous recording of rainfall and relative humidity >= 81 % (day 1) and relative humidity > 70 % at the second day) was the most strongly correlated with fb1 and fb2 (kendall coefficient: τ: 0.63 and 0.52 respectively) and was included in simple and bivariate regression logistic models with txm (mean maximum temperature). a trivariate model integrated for two interactive variables and txm achieved the highest accuracy of prediction, classifying correctly 93 % of cases. the environmental variables identified in this study stimulate f. verticillioides infection and can explain the variability in fumonisin levels at harvest. these results could be useful for the rational management of both disease and mycotoxin.
Analysing a Pricing Policy for a Home Centre: A Case Study  [PDF]

Abstract:

One critical aspect of retailer category management is pricing the items in order to maximize total profits. To define an appropriate pricing policy, a retailer should evaluate how changes in prices of a set of items may impact their shelves or inter demands. In this setting, elasticities play a major role. In addition, a proper policy can be defined from different points of view. In this paper, estimation of a profit function and its maximization under different scenarios is used as a tool to analyze such policy. Estimation of this function is performed through a previous selection of items within a home center category. Then, an adequate AIDS model allowing calculation of elasticities is fitted. Moreover, a profit function is defined in terms of prices and demands. This functionis linearized for the following two purposes, to express it in terms of elasticities, and to maximize it more easily under the consideration of different sets of item prices defined in a convex set. Then, confidence intervals for the total and marginal profits were built to gather the randomness of demands. The results are applied to the selected items in a home center that behaves as a monopoly in the area.

Advances in Historical Studies (AHS) , 2016, DOI: 10.4236/ahs.2016.52008
Abstract: This paper presents the role of the tobacco warehouses in the urban transformation of the provincial Greek city of Agrinio. It covers the period from the establishment of the Greek state in 1830 to the end of the interwar period, with special focus on the 1920s and 1930s. The study of this particular city is done within the broader historical environment of the Greek state, in which urban planning and architecture are among the more general issues raised by the historical conditions. The new data brought to light by the study show the significance of the tobacco warehouses in shaping the city of Agrinio, as well as the influences from Central Europe on local industrial architecture during the interwar years.
