Friedrich Hölderlin en la obra de Luis Cernuda

Cernuda tradujo a Hölderlin sin saber alemán, sin ser traductor. La obra de Hölderlin apenas era conocida y casi no había sido editada en lengua española. ¿Cómo lo hizo? ¿Realmente influyó la obra del poeta alemán en su poesía, como él lo afirmaba? He aquí una aproximación a estas cuestiones

Colonic perianastomotic carcinogenesis in an experimental model

Background To examine the effect of anastomosis on experimental carcinogenesis in the colon of rats. Methods Forty-three 10-week-old male and female Sprague-Dawley rats were operated on by performing an end-to-side ileorectostomy. Group A:16 rats received no treatment. Group B: 27 rats received 18 subcutaneous injections weekly at a dose of 21 mg/kg wt of 1–2 dimethylhydrazine (DMH), from the eighth day after the intervention. Animals were sacrificed between 25–27 weeks. The number of tumours, their localization, size and microscopic characteristics were recorded. A paired chi-squared analysis was performed comparing tumoral induction in the perianastomotic zone with the rest of colon with faeces. Results No tumours appeared in the dimethylhydrazine-free group. The percentage tumoral area was greater in the perianastomotic zone compared to tumours which had developed in the rest of colon with faeces (p = 0.014). Conclusion We found a cocarcinogenic effect due to the creation of an anastomosis, when using an experimental model of colonic carcinogenesis induced by DMH in rats.

La tradición inglesa en la obra de Jorge Luis Borges

En este artículo analizo las afinidades existentes entre la"tradición inglesa", en sus expresiones filosóficas y literarias, y la obra de Borges, quien llegó a considerarse"escritor inglés en lengua española". En la primera parte estudio la enorme simpatía filosófica y estética que Borges sentía por el pragmatismo de William James. En la segunda parte trato de mostrar que dicha simpatía no se detenía en el autor de Pragmatism sino que se extendía a toda la"tradición inglesa". Ciertamente, lo que podemos considerar las características generales de la tradición inglesa-escepticismo, nominalismo, antisistematismo, librepensamiento y un determinado sentido del humor-, forman un temperamento filosófico-literario enormemente afín al que constatamos en la obra de Jorge Luis Borges. En la tercera y última parte analizo cómo dicho"espíritu" filosófico no forma parte de una supuesta idiosincrasia nacional, concebida en términos esencialistas, sino de un determinado proceso histórico que hizo que permitió que en Inglaterra perdurasen ciertos valores del humanismo mientras que en el resto de Europa el racionalismo arramblaba con ellos. De este modo, tanto el temperamento filosófico de Borges como el de la tradición inglesa se remiten a una tradición humanística que supuso, a su vez, en el siglo XVI, el renacimiento de una milenaria tradición escéptica que había sido arrinconada por el dogmatismo de la era medieval.

Does ear C sink strength contributes to the overcoming of photosynthetic acclimation of wheat plants exposed to elevated CO2?

Wheat plants (Triticum durum Desf., cv. Regallo) were grown in the field to study the effects of contrasting [CO2] conditions (700 versus 370 μmol mol−1) on growth, photosynthetic performance, and C management during the post-anthesis period. The aim was to test whether a restricted capacity of sink organs to utilize photosynthates drives a loss of photosynthetic capacity in elevated CO2. The ambient 13C/12C isotopic composition (δ13C) of air CO2 was changed from-10.2 in ambient [CO2] to-23.6 under elevated [CO2] between the 7th and the 14th days after anthesis in order to study C assimilation and partitioning between leaves and ears. Elevated [CO2] had no significant effect on biomass production and grain filling, and caused an accumulation of C compounds in leaves. This was accompanied by up-regulation of phosphoglycerate mutase and ATP synthase protein content, together with down-regulation of adenosine diphosphate glucose pyrophosphatase protein. Growth in elevated [CO2] negatively affected Rubisco and Rubisco activase protein content and induced photosynthetic down-regulation. CO2 enrichment caused a specific decrease in Rubisco content, together with decreases in the amino acid and total N content of leaves. The C labelling revealed that in flag leaves, part of the C fixed during grain filling was stored as starch and structural C compounds whereas the rest of the labelled C (mainly in the form of soluble sugars) was completely respired 48 h after the end of labelling. Although labelled C was not detected in the δ13C of ear total organic matter and respired CO2, soluble sugar δ13C revealed that a small amount of labelled C reached the ear. The 12CO2 labelling suggests that during the beginning of post-anthesis the ear did not contribute towards overcoming flag leaf carbohydrate accumulation, and this had a consequent effect on protein expression and photosynthetic acclimation.

Runoff and sediment production in a Mediterranean basin under two different land uses

This study analyses the infl uence of two diff erent land uses on the hydrology of the Vernegà experimental basin between the years 2005 and 2009. It is located in the Northeast of the Iberian Peninsula and is infl uenced by a Mediterranean climate, with an average annual rainfall of 646 mm. The study of rainfall distributi on in the 1982 to 2009 period shows that the majority occurs during autumn, winter, and spring representi ng 33.2%, 25.5%, and 25.7% respecti vely of the total annual rainfall. Surface runoff is concentrated from October to June. Between 2005 and 2009, total runoff was 242.38 mm at the"Bosc" gauging stati on, which drains an area of 1.60 km2, and 298.54 mm at the"Campàs" gauging stati on, which drains an area of 2.57 km2 and is located at the outlet of the basin. More than 80% of the total surface runoff yielded during the study period corresponds to the 2005-2006 hydrologic year. Finally, Campàs gauging stati on registers a higher total runoff than Bosc gauging stati on. Part of this phenomenon may be due to the intercepti on of rainfall and plant biomass in the forested area of the basin. In relati on to the sediment yield, an overall increase in the two basins has been detected. Recent forest management practi ces undertaken in the catchment area are considered to be one of the most important reasons for this change.

El escepticismo identitario en la obra de Jorge Luis Borges

Este trabajo estudia la actitud de Borges respecto de la identidad, en general, y la identidad nacional, en particular. En la primera parte realizo una breve exposición de la tradición escéptica, de la que Borges es deudor, centrándome especialmente en el tratamiento que ésta le da al tema de la identidad. En la segunda parte, estudio de qué modo el escepticismo identitario se concreta en la obra de Jorge Luis Borges ; ABSTRACT: This paper explores the attitude of Borges with regard to identity, specifically the national identity. In the first part I study the skeptic tradition, that is predominant in Borges works, specially in connexion with the subject of identity. In the second part, I study how identitary skepticism appears in borgean litterature. KEYWORDS: Jorge Luis Borges. Skepticism. Identity. Nationalism. Latin american literature. Michel de Montaigne.

Terror cognoscitivo y terror metafísico en la obra de Jorge Luis Borges

Los cuentos de Jorge Luis Borges pertenecen, de algún modo, al género de la literatura de terror. No en un sentido estricto, claro está, pero tampoco en un sentido meramente metafórico. Ciertamente, los cuentos que integran Ficciones o El Aleph aterrorizan a todo el mundo, pues muchos no los leen por miedo de no entenderlos y el resto, al leerlos, se ven embargados por ese terror metafísico que provoca la violentación de nuestros modos de entender la realidad. Borges es, pues, un terrorista, pero un terrorista apaciguador, puesto que busca aterrorizarnos con el objetivo de liberarnos del miedo. Se trata, por así decirlo, de un miedo homeopático, de un purgante que ha de ser expulsado junto con todo aquello que buscaba eliminar. Mi intención es estudiar de qué modo podemos sostenerle la mirada a los cuentos de Borges, con el doble objetivo de posibilitar su lectura a aquellos que los evitan por miedo a no entenderlos y de ayudar a aquellos que osan leerlos a superar el miedo mediante el cual Borges pretende serenarnos.

Escepticismo y conservadurismo progresista en la obra de Jorge Luis Borges

A lo largo de más de dos milenios los pensadores escépticos han compartido concepciones políticas semejantes. El hecho de que muchos de estos rasgos sean reconocibles en Borges refuerza la interpretación escéptica de su obra que he defendido en mi tesis doctoral y en diversos artículos. Analizaré, en primer lugar, la actitud política, conservadora, tradicionalmente asociada al escepticismo; en segundo lugar, el modo en que Borges participa de dicho conservadurismo progresista; y, en tercer lugar, aquellas características del pensamiento borgeano que pueden llevarnos a considerarlo como un intelectual según la definición que propone del mismo Edward W. Said en Representations of the intellectual.

Improving Label Space Usage for Ethernet Label Switched Paths

Ethernet is becoming the dominant aggregation technology for carrier transport networks; however, as it is a LAN technology, native bridged ethernet does not fulfill all the carrier requirements. One of the schemes proposed by the research community to make ethernet fulfill carrier requirements is ethernet VLAN-label switching (ELS). ELS allows the creation of label switched data paths using a 12-bit label encoded in the VLAN TAG control information field. Previous label switching technologies such as MPLS use more bits for encoding the label. Hence, they do not suffer from label sparsity issues as ELS might. This paper studies the sparsity issues resulting from the reduced ELS VLAN-label space and proposes the use of the label merging technique to improve label space usage. Experimental results show that label merging considerably improves label space usage

Optimal Traffic Grooming in WDM using Lighttours

Recent developments in optical communications have allowed simpler optical devices to improve network resource utilization. As such, we propose adding a lambda-monitoring device to a wavelength-routing switch (WRS) allowing better performance when traffic is routed and groomed. This device may allow a WRS to aggregate traffic over optical routes without incurring in optical-electrical-optical conversion for the existing traffic. In other words, optical routes can be taken partially to route demands creating a sort of "lighttours". In this paper, we compare the number of OEO conversions needed to route a complete given traffic matrix using either lighttours or lightpaths
