Jada sei urte igaro dira azkeneko hamarkadetan pairatu dugun krisialdi ekonomiko gogorrena iritsi zela eta, kimuak kimu, oraindik ere egundoko sarraskiak sorrarazten dihardu. Urakan bat bailitzan agertu zen gure artean eta guztiongan aparteko eragina izan du: gure kontzientzia ekonomikoa astintzeaz gain orain arte normaltzat ematen genituen hainbat portaera kolokan jarri ditu. Kaltetuen zerrenda luze horretan herritarrengandik gertuen dauden erakunde publikoak agertzen dira: udalak. Artikulu honetan krisiak Gipuzkoako udalen finantza-egoeretan izan duen eragina aztertuko da, eragin negatiboa pairatu zuten lehendabiziko urtetik abiatu (2008) eta aurrekontu likidatuak dauzkagun azkeneko urtera (2012) iritsi arte. Udalen egoera ekonomiko-finantzarioa zein den jakiteko baliagarriak diren, transferentzia arruntekiko menpekotasuna, funtzionamendu gastuak, aurrezki gordina, aurrezki garbia, legezko zorpetze maila, zor bizia eta gastu orokorretarako diruzaintza-gerakina adierazleen egoera eta bilakaerak aurkeztuko dira.

Papillomaviruses (PVs) are widespread pathogens. However, the extent of PV infections in bats remains largely unknown. This work represents the first comprehensive study of PVs in Iberian bats. We identified four novel PVs in the mucosa of free-ranging Eptesicus serotinus (EserPV1, EserPV2, and EserPV3) and Rhinolophus ferrumequinum (RferPV1) individuals and analyzed their phylogenetic relationships within the viral family. We further assessed their prevalence in different populations of E. serotinus and its close relative E. isabellinus. Although it is frequent to read that PVs co-evolve with their host, that PVs are highly species-specific, and that PVs do not usually recombine, our results suggest otherwise. First, strict virus-host co-evolution is rejected by the existence of five, distantly related bat PV lineages and by the lack of congruence between bats and bat PVs phylogenies. Second, the ability of EserPV2 and EserPV3 to infect two different bat species (E. serotinus and E. isabellinus) argues against strict host specificity. Finally, the description of a second noncoding region in the RferPV1 genome reinforces the view of an increased susceptibility to recombination in the E2-L2 genomic region. These findings prompt the question of whether the prevailing paradigms regarding PVs evolution should be reconsidered.

Poly(dimethylsiloxane) (PDMS) is usually considered as a dielectric material and the PDMS microchannel wall can be treated as an electrically insulated boundary in an applied electric field. However, in certain layouts of microfluidic networks, electrical leakage through the PDMS microfluidic channel walls may not be negligible, which must be carefully considered in the microfluidic circuit design. In this paper, we report on the experimental characterization of the electrical leakage current through PDMS microfluidic channel walls of different configurations. Our numerical and experimental studies indicate that for tens of microns thick PDMS channel walls, electrical leakage through the PDMS wall could significantly alter the electrical field in the main channel. We further show that we can use the electrical leakage through the PDMS microfluidic channel wall to control the electrolyte flow inside the microfluidic channel and manipulate the particle motion inside the microfluidic channel. More specifically, we can trap individual particles at different locations inside the microfluidic channel by balancing the electroosmotic flow and the electrophoretic migration of the particle.

[ES] El objetivo del artículo es explorar la potencialidad de la Evaluación Multi-criterio Social como enfoque metodológico para evaluar Espacios Naturales Protegidos (ENP) e iniciar un proceso de discusión sobre la conveniencia de incorporar esta metodología para la gobernanza de la Red Natura 2000 de la Comunidad Autónoma de Euskadi. Del caso de estudio analizado se desprende que la inclusión de la población local en un proceso participativo dirigido a la planificación y manejo de los ENP contribuiría a reducir el número y calado de conflictos potenciales. Asimismo, facilitaría la gobernanza efectiva de los ENP, lo que parece un reto ineludible para que las áreas protegidas logren sus objetivos y funciones.

Eel trapping seems to be one of the possibilities to replace the German eel trawl fishery on cutters in the Baltic with a high amount of unwanted and discarded bycatch by a more effective method. To prepare our own practical application the highly developed mechanized eel trap fishery on a commercial vessel in the Netherlands was studied. The results of this study are described in the this article.
