Philosophy and language in young Nietzsche
2015
Resumo:O objetivo deste estudo é a exposição da filosofia da linguagem que Nietzsche apresenta em suas primeiras obras, sobretudo em seu decisivo escrito póstumo de 1873. São considerados três aspectos da trajetória de Nietzsche. Seu interesse pela linguagem poética e musical, desde a juventude; sua formação em filologia clássica; suas investigações filosóficas sobre o tema. Pretendemos mostrar como, nesse período, se parte de uma concepção metafísica para uma visão mais linguística. Nietzsche parte do fundamento metafísico para uma versão da linguagem como relação de signos e símbolos. Abstract:The purpose of this study is the explanation of the philosophy of language that Nietzsche presen…
SOUTH AMERICAN COLLABORATION IN SCIENTIFIC PUBLICATIONS ON LEISHMANIASIS: BIBLIOMETRIC ANALYSIS IN SCOPUS (2000-2011)
2014
Objetivos: Evaluar la producción y la red de colaboración de investigación sobre leishmaniasis en Sudamérica. Métodos: Se realizó un estudio bibliométrico usando la base de datos SCOPUS. La unidad de análisis fueron los artículos originales de investigación publicados desde el año 2000 hasta 2011, realizados sobre leishmaniasis y que incluyeron al menos un autor sudamericano. Se obtuvieron para cada artículo: nombre de la revista, idioma, año de publicación, número de autores, instituciones, países y otras variables. Resultados: 3174 artículos fueron publicados, 2.272 de ellos eran artículos originales. Se identificaron 1.160 firmas institucionales diferentes, 58 países y 398 revistas cient…
Hygrothermal conditions in Cross Laminated Timber (CLT) dwellings
2020
The use of CLT has been increasing the last decade, and a subsequently focus on documentation of the accompanying indoor climate and exposed wooden surfaces on human well-being. This study presents the results of a measurement campaign conducted over one year of a CLT apartment building in Grimstad, Norway. The apartment building consists of three floors with 35 apartments and comply with the Norwegian passive house standard and energy grade A. Measurements of the relative humidity (RH), indoor air temperature and wood moisture content (MC) were performed in the exposed CLT spruce panels in three apartments in two different floors. The results from the three apartments show a relatively sma…
The reconstruction of easterly wind directions for the Eifel region (Central Europe) during the period 40.3–12.9 ka BP
2010
Abstract. A high resolution continuous reconstruction of last glacial wind directions is based on provenance analysis of eolian sediments in a sediment core from the Dehner dry Maar in the Eifel region (Germany). This Maar is suitable to archive easterly wind directions due to its location west of the Devonian carbonate basins of the Eifel-North-South-Zone. Thus, eolian sediments with high clastic carbonate content can be interpreted as an east wind signal. The detection of such east wind sediments is applied by a new module of the RADIUS grain size analyze technique. The investigated time period from 40.3–12.9 ka BP can be subclassified in three units: The first unit covers the periods of …
Numerical study of the October 2007 flash flood in the Valencia region (Eastern Spain): the role of orography
2010
Abstract. A torrential rain event took place in the Valencia region in October 2007, mainly affecting coastal areas and nearby mountains in the center-south of the region, in northern Alicante province. More than 400 mm in 24 h were recorded at some stations in these areas, with lower accumulations in the rest of the region where rainfall was less intense. In the first part of this work a description of the meteorological situation is given. The synoptic frame of the event is characterised by an advection of easterly maritime winds across the Western Mediterranean, lasting for at least 48 h, driving moist air towards the Iberian Peninsula eastern coast and the presence of an upper level iso…
Estimation of synthetic flood design hydrographs using a distributed rainfall–runoff model coupled with a copula-based single storm rainfall generator
2014
Abstract. In this paper a procedure to derive synthetic flood design hydrographs (SFDH) using a bivariate representation of rainfall forcing (rainfall duration and intensity) via copulas, which describes and models the correlation between two variables independently of the marginal laws involved, coupled with a distributed rainfall–runoff model, is presented. Rainfall–runoff modelling (R–R modelling) for estimating the hydrological response at the outlet of a catchment was performed by using a conceptual fully distributed procedure based on the Soil Conservation Service – Curve Number method as an excess rainfall model and on a distributed unit hydrograph with climatic dependencies for the …
Assessment of the changes of COD and color in rivers of Latvia during the last twenty years
1998
Analysis of long-term records of the concentrations of water color and chemical oxygen demand for nine river sites in Latvia is reported. The period of observations lasted for the last 20 years. Characteristic features of data include non-normal distributions, serial correlation, seasonality and presence of mostly significant downward trends. In Latvia, the main water quality changes could be explained by the changes of anthropogenic impact and the type of catchment management over the last 20 years.
Bacterial Diversity in a Dynamic and Extreme Sub-Arctic Watercourse (Pasvik River, Norwegian Arctic)
2020
Microbial communities promptly respond to the environmental perturbations, especially in the Arctic and sub-Arctic systems that are highly impacted by climate change, and fluctuations in the diversity level of microbial assemblages could give insights on their expected response. 16S rRNA gene amplicon sequencing was applied to describe the bacterial community composition in water and sediment through the sub-Arctic Pasvik River. Our results showed that river water and sediment harbored distinct communities in terms of diversity and composition at genus level. The distribution of the bacterial communities was mainly affected by both salinity and temperature in sediment samples, and by oxygen…
Candida spp. Determination and Th1/Th2 Mixed Cytokine Profile in Oral Samples From HIV+ Patients With Chronic Periodontitis
2019
Background: Chronic periodontitis (CP), caused by bacteria and fungi, appears in up to 66% of HIV-patients. The impact and association of HIV-treatment (HAART) and Candida itself has not been properly evaluated in the development and progression of CP. The immunopathogenesis is characterized by CD4+ T-cells activation and the balance between the T-helper 1 (Th1) and T-helper 2 (Th2) or a mixed cytokine profile. Currently, the associated causes of an immune response in HIV-patients with CP is controversial. Our aims were the determination of Candida spp. and cytokine profile in oral samples from HIV-positive patients with CP, considering the CD4+ T cells levels and HAART use.Methods: From 50…
Barcelona vista pels narradors del vuit-cents
2014
L’article s’ocupa de les representacions o imatges de la ciutat de Barcelona en la prosa literària catalana del segle xix, especialment en el quadre de costums i la novel·la, que s’examinen com a expressions de cultura urbana. Aquesta literatura, associada a un cert concepte de modernitat, avança flanquejada per l’historicisme i el ruralisme mitificadors dels escriptors lligats als ideals conservadors de la Renaixença. L’article dibuixa la trama de motius o de trets idiosincràtics urbans en la prosa destil·lada pels escriptors del vuit-cents, primer en llengua castellana i, a partir dels anys 60, en llengua catalana. Així, fa un recorregut per la Barcelona vella i la Barcelona nova, abans i…
