Precision mass measurements of neutron-rich nuclei between N=50 and 82
2012
Our knowledge of binding energies of neutron-rich nuclei has experienced a major revision during the last five years due to the introduction of Penning-trap based mass measurements. New mass values for nearly 300 nuclides produced in fission with uncertainties of 10 keV or less have become available. The data produced at three Penning trap facilities at Jyvaskyla, CERN-ISOLDE and Argonne cover all isotopic chains from Ni to Pr, except iodine. In this talk some of this data is reviewed and applied using the mass differentials such as two-neutron binding energy and odd-even staggering to probe their sensitivity on changes in nuclear structure and on the strength of the N=82 shell gap and asso…

Population of neutron-rich nuclei around 48ca with deep inelastic collisions
2009
The deep inelastic reaction 48Ca+64Ni at 6 MeV/A has been studied using the CLARA–PRISMA setup. Angular distributions for pure elastic scattering and total cross-sections of the most relevant transfer channels have been measured. The experimental results are compared with predictions from a semiclassical model, showing good agreement for the presently analyzed few neutrons transfer channels. The decay of the most intense reaction products has also been studied, giving indications of the population of states with very short lifetimes. Gadea Raga, Andrés, Gadea.Andres@ific.uv.es
Food plant diversity as broad-scale determinant of avian frugivore richness.
2007
The causes of variation in animal species richness at large spatial scales are intensively debated. Here, we examine whether the diversity of food plants, contemporary climate and energy, or habitat heterogeneity determine species richness patterns of avian frugivores across sub-Saharan Africa. Path models indicate that species richness of Ficus (their fruits being one of the major food resources for frugivores in the tropics) has the strongest direct effect on richness of avian frugivores, whereas the influences of variables related to water–energy and habitat heterogeneity are mainly indirect. The importance of Ficus richness for richness of avian frugivores diminishes with decreasing sp…

Enriched Environments for Rodents and their Interaction with Nicotine Administration
2012
An active lifestyle throughout the life cycle seems to delay cognitive aging and dementia and has also been evaluated as an intervention against addiction to cocaine and other drugs of abuse. In epidemiological studies with humans, it has proved difficult to separate the cognitive, social and physical components from other variables that influence lifestyle. Studies in animal models are useful for evaluating the impact of each of these factors and for uncovering the underlying mechanisms of the benefits of complex environments. Preclinical studies have employed the Environmental Enrichment paradigm (EE) which has been proposed as a preclinical model of positive life experiences in humans. E…
Individual Differences in Novelty-Seeking and Behavioral Responses to Nicotine: A Review of Animal Studies
2010
Individual differences in the behavioral responses to a novel environment have been proposed as a research tool to predict responsiveness to other behavioral tasks, response to certain events and individual vulnerability to nicotine addiction. In rats and mice, novelty seeking (defined as enhanced specific exploration of novel situations) is a complex behavior confirmed by a large body of neurochemical, endocrinological and behavioral data. We review the main standardized procedures employed to measure the novelty seeking trait in rodents and the ontogeny of this behavior throughout the life-span taking into account that novelty seeking can be permanently modified as a consequence of partic…
Tragedia katharsikseen tähtäävänä toimintana ja dionyysis-apollonisten voimien pariutumisena : Aristoteleen ja Nietzschen tragediakäsityksistä
2016
Tämän pro gradu -työn päätarkoituksena on tarkastella Aristoteleen (384‒322 eaa) ja Friedrich Nietzschen (1844‒1900) käsityksiä tragediasta sekä vertailla niitä keskenään. Lisäksi sivuan tragedian kuolemasta käytävää keskustelua pohtimalla näiden kahden ajattelijan kautta sitä, onko tragedia mahdollinen nykypäivän teatterissa. Aristoteleen Runousoppi (n. 330‒320-luku eaa) on länsimaisen draaman klassikkoteos, joka käsittelee tragediaa ennen kaikkea poetiikan näkökulmasta. Sen juonta korostavalla tragedian määritelmällä ja katharsiksen käsitteellä on ollut kauaskantoinen vaikutus. Aristoteleen määritelmän ydin on, että tragedia on esitys loppuunsaatetusta ja kokonaisesta toiminnasta, joka sä…
