The occurrence and bioavailability of retene and resin acids in sediments of a lake receiving BKME (bleached kraft mill effluent)
1999
Retene (7-isopropyl-1-methylphenantrene) is an alkyl substituted PAH derived primarily from bacterial aromatization of abietic type resin acids. Retene has been shown to induce cytochrome P450 1A in rainbow trout whereas e.g. dehydroabietic acid does not induce it. We analysed resin acids and retene in sediments from seven sites receiving pulp and paper mill effluents from 4 mills, and from two reference sites. All mills have employed treatment of waste waters by activated sludge. The highest concentration of retene measured in sediment was 1600 μg/g d.w. (11 700 μg/g organic carbon, OC) while the highest concentration of resin acids was 1500 μg/g d.w. (9 300 μg/g OC). Downstream from the p…
Occurrence of retene and resin acids in sediments and fish bile from a lake receiving pulp and paper mill effluents
1999
Retene (7-isopropyl−1-methylphenanthrene) is a dialkyl-substituted PAH derived thermally and microbially from dehydroabietic acid. We have analyzed for retene and several resin acids in sediments at five depths at several sites in a lake receiving effluents from three pulp and paper mills, and two upstream reference sites. The highest concentration of retene was 1,600 μg/g dry weight (11,700 μg/g organic carbon [OC]) and of total resin acids was 1,500 μg/g dry weight (9,300 μg/g OC). Twelve kilometers downstream from the point of bleached-kraft mill effluent (BKME) discharge, the concentration of retene at a depth of 5 to 10 cm was 16 μg/g dry weight (650 μg/g OC) and of resin acids was 139…

Nuevo Orden Mundial. Narraciones sobre el poder y superhéroes en el cómic mainstream estadounidense de Stormwatch a Black Summer (1996-2008)
2009
Los cómics de superhéroes han sido estudiados por la crítica, sobre todo, como artefactos mitológicos de implicaciones morales y filosóficas. Pero desde finales de los noventa una parte importante del cómic de superhéroes mainstream se ha convertido en una narrativa simbólica sobre el poder en el mundo contemporáneo, alimentándose del discurso y los acontecimientos políticos, textualizando de manera sutil, política y moralmente provocadora, acontecimientos reales como el nuevo terrorismo y las respuestas militares a éste, la polarización de la vida política americana o el (des)equilibrio de poder mundial. Este estudio de la producción de Warren Ellis y Mark Millar muestra la importancia de …

Profetismo político, milenarismo y creencias mesiánicas en el último periodo del reinado de Fernando el Católico (1500-1516)
2019
This study analyzes the presence of messianic and millennial beliefs in the last period of Ferdinand the Catholic?s reign. For this and after a brief state of the art, we analyze the use of the Christian prophecy of the millennium in speeches and memorials arising from the war in Naples, the North African campaign and the Pisan schism.

Confirmation of in situ exposure of fish to secondary treated bleached-kraft mill effluent using a laboratory simulation
1998
To corroborate the responses in whitefish (Coregonus Iavaretus L.) exposed to elemental chlorine free (ECF) bleached-kraft pulp mill effluent (BKME) in situ, a 30-d laboratory exposure was carried out at concentrations simulating the field conditions. The flow-through exposures were conducted at four secondary (activated sludge) treated effluent (STE) concentrations: 1.3, 2.3, 3.5, and 7%. To evaluate the role of the secondary treatment, fish were also exposed to one concentration (3.5%) of pretreated effluent (PTE) from the mill. Compared to the control, whitefish liver 7-ethoxyresorufin-O-deethylase (EROD) activity was twofold in fish exposed to 3.5% STE, which was similar to monooxygenas…
