The effects of different combinations of fixed and moving bed bioreactors on rainbow trout (Oncorhynchus mykiss) growth and health, water quality and…
2019
The effect of bioreactor design on nitrification efficiency has been well studied, but less is known about the overall impacts on water quality. Besides nitrification, submerged fixed bed bioreactors (FBBR) trap fine solid particles, whereas moving bed bioreactors (MBBR) grind solids, possibly increasing solids and particle accumulation in the system. In this experiment, the effects of different combinations of fixed bed and moving bed bioreactors on water quality, solids removal, particle size distribution, fish health based on histopathological changes and nitrification efficiency were studied in laboratory scale recirculating aquaculture systems (RAS) with rainbow trout (Oncorhynchus myk…

La solitudine dell'intellettuale in Una donna di casa di Vitaliano Brancati
2001
Carattere precipuo della produzione drammaturgica di Brancati - a torto considerata marginale rispetto a quella narrativa e saggistica dell'autore - è l'impegno etico-civile, perseguito con costanza sin dagli esordi. Significativa, inoltre, è l'importanza acquisita dalla figura femminile; risulta esemplare, in tal senso, la commedia "Una donna di casa", qui esaminata sia in relazione alle scelte formali dell'autore che ai successivi adattamenti scenici.L'articolo è arricchito inoltre da un'intervista inedita al regista e agli interpreti di una recente messinscena brancatiana: Alvaro Piccardi, Paola Gassman, Ugo Pagliai.
Iniciativas pedagógicas para el “uso responsable” de los dispositivos móviles en centros de educación secundaria obligatoria
2014
Los dispositivos tecnológicos móviles son utilizados intensivamente por los jóvenes en edad escolar, con independencia del lugar en el que se encuentren. Según un estudio reciente, el 85% de los jóvenes de la unión europea utiliza Internet casi diariamente, el 77% ve televisión y el 66% maneja las redes sociales (VVAA 2014. Jóvenes y comunicación. Madrid: Centro Reina Sofía). Pese a los indudables beneficios que se le atribuyen al manejo de estas tecnologías, aparecen también algunos riesgos ante los que los menores pueden verse afectados al realizar un ‘uso no responsable’. Dados los posibles conflictos que pueden surgir y el aumento de la preocupación entre los distintos agentes escolares…
Yleisten kielitutkintojen laatijoiden käsityksiä kielestä ja tehtävien laadinnasta
2012
YLEISTEN KIELITUTKINTOJEN LAATIJOIDEN KÄSITYKSIÄ KIELESTÄ JA TEHTÄVIEN LAADINNASTA Jyväskylä: Soveltavan kielentutkimuksen keskus, Jyväskylän yliopisto 2012, Lisensiaattitutkielma. Tutkimuksessa tarkasteltiin yleisten kielitutkintojen laatijoiden käsityksiä kielestä ja heidän kokemuksiaan ja näkemyksiään tehtävien laadinnasta. Yleisissä kielitut-kinnoissa toimii jokaisessa yhdeksässä tutkintokielessä laatijatiimi, jossa työskentelee 3–10 laatijaa tutkintokielestä riippuen. Aktiivisesti toimivia laatijoita on noin 40 laatijaa, joista tutkimukseen osallistui 32 laatijaa eri tutkintokielten laatijatiimeistä. Tutkimusaineisto kerättiin vuosina 2008–2010, ja se koostui kirjallisesta kyselystä ja…

Gill area explains deviations from body size–metabolic rate relationship in teleost fishes
2022
Whether gill area constrains fish metabolism through oxygen limitation is a debated topic. Here, the authors provide insights into this question by analysing mass-specific metabolic rates across 44 teleost fishes extracted from FishBase. They explore whether species deviations from metabolic rates predicted by body mass can be explained by species gill area. They show that the gill area explains c. 26%–28% of species-level deviations from mass-specific metabolic rates. Their findings suggest that gill area might indeed be one of the factors limiting metabolic rate in fishes.

Prenatal thyroid hormones accelerate postnatal growth and telomere shortening in wild great tits
2021
AbstractEarly-life environment is known to affect later-life health and disease, which could be mediated by the early-life programming of telomere length, a key hallmark of ageing. According to thefetal programming of telomere biology hypothesis, variation in prenatal exposure to hormones is likely to influence telomere length. Yet the contribution of key metabolic hormones,i.e. thyroid hormones (THs), has been largely ignored. We recently showed that in contrast to predictions, exposure to elevated prenatal THs increased postnatal telomere length in wild collared flycatchers, but the generality of such effect, its underlying proximate mechanisms and consequences on survival have not been i…
