Millora en la creació i configuració automatitzada de dispositius a la xarxa lliure Guifi.net

Guifi.net es una red libre de telecomunicaciones construida a iniciativa de los propios participantes que, mediante un acuerdo entre iguales, se interconectan para compartir servicios y recursos. Del vínculo filosófico con el software libre deriva que toda la información sea pública, mientras que del agnosticismo tecnológico, la utilización de cualquier dispositivo del mercado. Por esto existe el 'unsolclic', una secuencia de órdenes de confi guración genérica de dispositivos y verdadero factor de éxito. El objetivo del proyecto es mejorar el proceso de incorporación de nuevos dispositivos a la aplicación actual. Mediante una nueva gestión web y un sistema de plantillas estándar, los usuarios avanzados podran crear los confi guradores 'unsolclic' para los nuevos dispositivos del mercado y mantener los existentes con más facilidad y eficiencia.

Arte y desacuerdo: un estudio del proyecto Megafone.net de Antoni Abad a partir de las tesis estético-políticas de Jacques Rancière

Este trabajo tiene por objeto el estudio de las relaciones entre arte y política en el contexto del capitalismo neoliberal. Propone una lectura e interpretación de las tesis estético-políticas de Jacques Rancière incidiendo en dos ejes fundamentales de las mismas. De un lado, la elaboración de su concepto de política, planteado como un desacuerdo respecto a la hegemonía contemporánea del pensamiento neoliberal. Del otro, el modo en que su razonamiento se sostiene sobre una original reflexión estética, la cual desemboca en unaredefinición de las prácticas artísticas como medios eficaces de intervención política en la realidad. Es importante subrayar que esta investigación no se limita a una simple paráfrasis del pensamiento del filósofo francés. Así, sus ideas serán puestas en diálogo con lasaportaciones de otros autores y disciplinas y, sobre todo, se ensayará su pertinencia en el análisis de un caso concreto de estudio: el proyecto Megafone.net del artista catalán Antoni Abad, tomado como un ejemplo terminado del concepto de “arte político” elaborado por Rancière.

Contagion and efficiency in gross and net interbank payment systems

The increased fragility of the banking industry has generatedgrowing concern about the risks associated with the paymentsystems. Although in most industrial countries differentinterbank payment systems coexist, little is really knownabout their propierties in terms of risk and efficiency. Wetackle this question by comparing the two main types ofpayment systems, gross and net, in a framework whereuncertainty arises from several sources: the time ofconsumption, the location of consumption and the return oninvestment. Payments across locations can be made either bydirectly transferrring liquidity or by transferring claimsagainst the bank in the other location. The two mechanism areinterpreted as the gross and net settlement systems ininterbank payments. We characterize the equilibria in the twosystems and identify the trade-off in terms of safety andefficiency.

Rat splanchnic net oxygen consumption. Energetic implications

1. The blood flow, PO2, pH and PCO2 have been estimated in portal and suprahepatic veins as well as in hepatic artery of fed and overnight starved rats given an oral glucose load. From these data the net intestinal, hepatic and splanchnic balances for oxygen and bicarbonate were calculated. The oxygen consumption of the intact animal has also been measured under comparable conditions. 2. The direct utilization of oxygen balances as energy equivalents when establishing the contribution of energy metabolism of liver and intestine to the overall energy expenses of the rat, has been found to be incorrect, since it incorporates the intrinsic error of interorgan proton transfer through bicarbonate. Liver and intestine produced high net bicarbonate balances in all situations tested, implying the elimination (by means of oxidative pathways, i.e. consuming additional oxygen) of high amounts of H+ generated with bicarbonate. The equivalence in energy output of the oxygen balances was then corrected for bicarbonate production to 11-54% lower values. 3. Intestine and liver consume a high proportion of available oxygen, about one-half in basal (fed or starved) conditions and about one-third after gavage, the intestine consumption being about 15% in all situations tested and the liver decreasing its oxygen consumption with gavage.

Seasonal dynamics and net production of disolved organic carbon in an oligotrophic coastal environment

To understand dissolved organic carbon (DOC) seasonal dynamics in a coastal oligotrophic site in the north-western Mediterranean Sea, we monitored DOC concentrations monthly over 3 yr, together with the meteorological data and the food-web-related biological processes involved in DOC dynamics. Additional DOC samples were taken in several inshore−offshore transects along the Catalan coast. We found DOC concentrations of ~60 µmol C l−1 in winter, with increasing values through the summer and autumn and reaching 100 to 120 µmol C l−1 in November. There was high inter-annual variability in this summer DOC accumulation, with values of 36, 69 and 13 µmol C l−1 for 2006, 2007 and 2008, respectively. The analysis of the microbial food-web processes involved in the DOC balance did not reveal the causes of this accumulation, since the only occasion on which we observed net DOC production (0.3 ± 1 µmol C l−1 d−1 on average) was in 2007, and the negative DOC balance of 2006 and 2008 did not prevent DOC accumulating. The DOC accumulation episodes coincided with low rates of water renewal (average 0.037 ± 0.021 d−1 from May to October) compared with those of winter to early spring (average 0.11 ± 0.048 d−1 from November to April). Indeed, the amount of DOC accumulated each year was inversely correlated with the average summer rainfall. We hypothesize that decreased DOC turn-over due to photochemical or biological processes mostly active during the summer and low water renewal rate combine to determine seasonal DOC accumulation and influence its inter-annual variability.
