L' esport a la Televisió de Catalunya: la creació d'un canal esportiu-cultural: Canal 33

Aquest treball es va presentar a l’Assignatura de Campus “Esport, Olimpisme i Societat” del curs 1995/96 i tracta de l'evolució de la programació esportiva a la Televisió de Catalunya des de la seva creació, així com dels orígens i història del Canal 33.

Microdiálisis cerebral de alta resolución: Estudio del perfil funcional y estructural de las membranas de 100 kDa

La microdiàlisi és una tècnica de neuromonitoratge que permet el mostreig continu del contingut molecular i iònic de l’espai intersticial cerebral. Aquesta tècnica es basa en la implantació d’un catèter en el parènquima cerebral humà de manera mínimament invasiva. Actualment, la microdiàlisi s’ha implantat de manera rutinària en moltes unitats de cures intensives pel neuromonitoratge de pacients amb lesions cerebrals agudes. No obstant, l’estudi in vivo del perfil temporal del proteoma en aquestes lesions i la correcta avaluació de la concentració de les molècules d’interès en el líquid extracel•lular cerebral requereix la determinació prèvia in vitro del percentatge de recuperació relativa de les proteïnes d’estudi.

Bowling for fascism: Social capital and the rise of the Nazi Party in Weimar Germany, 1919-33

Social capital a dense network of associations facilitating cooperation within a community typically leads to positive political and economic outcomes, as demonstrated by a large literature following Putnam. A growing literature emphasizes the potentially "dark side" of social capital. This paper examines the role of social capital in the downfall of democracy in interwar Germany by analyzing Nazi party entry rates in a cross-section of towns and cities. Before the Nazi Party's triumphs at the ballot box, it built an extensive organizational structure, becoming a mass movement with nearly a million members by early 1933. We show that dense networks of civic associations such as bowling clubs, animal breeder associations, or choirs facilitated the rise of the Nazi Party. The effects are large: Towns with one standard deviation higher association density saw at least one-third faster growth in the strength of the Nazi Party. IV results based on 19th century measures of social capital reinforce our conclusions. In addition, all types of associations veteran associations and non-military clubs, "bridging" and "bonding" associations positively predict NS party entry. These results suggest that social capital in Weimar Germany aided the rise of the Nazi movement that ultimately destroyed Germany's first democracy.

Study on the removal of biodegradable NOM from seawater using biofiltration

Despite the low biodegradability of seawater NOM, problems associated with biofouling are common in facilities that handle seawater. In this work, a fixed-film aerobic biofilter is proposed as an effective unit for preventing biofouling in such facilities. A packed-bed biofilter with an EBCT = 6 - 11 min was employed. The results demonstrated that the DOC is reduced by 6% and the BOD7 is reduced up to 15%. The LC-OCD analysis revealed that biofiltration abates the LMW neutrals and biopolymer fractions by 33 and 17%, respectively. However, the fractionation with UF membrane showed that the biofiltration process is able to degrade the more biodegradable compounds that have molecular weights that are greater than 1 kDa and compounds with molecular weights of less than 1 kDa. After biofiltration, the biological activity measured in terms of ATP removal was reduced by 60%. Finally, a test to evaluate the biofilm formation capacity of a water sample revealed reductions of ~94% when comparing biofiltered and non-biofiltered seawater. Therefore, a fixed-film aerobic biofiltration process could be a useful treatment for the removal of biodegradable organic matter from seawater and for improving the water quality in terms of less biofilm formation capacity.
