Seroprevalence of Toxoplasma gondii antibodies in wild dolphins from the Spanish Mediterranean coast.

2004

Although Toxoplasma gondii infection has been found occasionally in cetaceans, little is known of the prevalence of antibodies to T. gondii in wild dolphins. Antibodies to T. gondii were determined in serum samples from 58 dolphins stranded in the Spanish Mediterranean coast. Modified agglutination test was used to determine T. gondii antibodies, and a titer of 1:25 was considered indicative of T. gondii infection. Antibodies to T. gondii were found in 4 of 36 striped dolphins (Stenella coeruleoalba), in 2 of 4 common dolphins (Delphinus delphis), in 4 of 7 bottlenose dolphins (Tursiops truncatus), and in 1 harbour porpoise (Phocoena phocoena). Antibodies were not found in 9 Risso's dolphin…

From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…

2007

After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…

Fra stato di necessità ed (illecito) intervento economico: il terzo "bail out" della Grecia

2015

Il lavoro affronta due questioni poste dall'intervento economico del Fondo monetario internazionale e del MES nella crisi del debito greco: da un lato, quello della sostenibilità del debito stesso e dell'applicabilità dei principi di diritto internazionale in tema di stato di necessità; da un altro lato, quello del carattere particolarmente intrusivo delle condizioni poste alla Grecia e della sua valutazione alla luce del principio di non intervento negli affari interni.

Mismatches between objective parameters and measured perception assessment in room acoustics: a holistic approach

2014

Psychoacoustic research in the field of concert halls has revealed that many aspects concerning listening perception have yet to be totally understood. On the one hand, the objective room acoustics of performance spaces are reflected in parameters, some standardized and some not, but these are related to a limited number of perceptual attributes of human response. In general, these objective parameters cannot accurately describe the acoustic details due to their inherent simplification. Under these premises, impulse responses (576 receivers) are measured in 16 concert halls, according to standard procedures, and the perception and satisfaction of the occupants of the rooms are evaluated by …

Class Actions or Collective Redress: The Need for an Efficient European Tool

2014

Collective redress makes sense both in court-based litigation and in alternative dispute resolution (ADR). Yet while the courts generally have a good sense of collective redress (though arguably there is room for improvements), in the second framework, there are some contradictions from a dogmatic point of view. When collective interests come up in conflict, judicial coercion and a judicial structure are often needed to resolve the conflict. In addition, the absence of a voluntary agreement, especially from the abuser’s side, makes it more difficult to resolve conflicts using ADR. The future EU Directive in Consumer Collective Redress aims to bring a new era to the field. In this paper, I s…

Contextualization of Open Educational Resources in Asia and Europe

2014

Open Educational Resources (OER) are a promising concept for international collaborations: sharing, utilizing, and collaborating around OER across borders might help educational institutions and their staff to internationalize their activities. However, several barriers exist keeping stakeholders away from engaging in international collaborations. In this paper, we discuss the main challenges of OER uptake in international settings. Three case studies show potential solutions for OER uptake and collaboration in the European-Asian context. The case studies identify good practices, success factors and challenges. This paper provides a starting point for systematic analytical as well as design…

Metal-organic magnets with large coercivity and ordering temperatures up to 242°C.

2020

International audience; Magnets derived from inorganic materials (e.g., oxides, rare-earth–based, and intermetallic compounds) are key components of modern technological applications. Despite considerable success in a broad range of applications, these inorganic magnets suffer several drawbacks, including energetically expensive fabrication, limited availability of certain constituent elements, high density, and poor scope for chemical tunability. A promising design strategy for next-generation magnets relies on the versatile coordination chemistry of abundant metal ions and inexpensive organic ligands. Following this approach, we report the general, simple, and efficient synthesis of light…

Polarization of SrBi 2 Ta 2 O 9 ceramics at infra‐low frequencies

2009

Dielectric response in the SrBi2Ta2O9 ceramics is studied over a wide range of temperatures at fields up to Emax ≈ 18 kV/cm. Dependence of dielectric permittivity on field intensity is analyzed at different temperatures. A series of polarization loops are obtained at frequencies 0.1 Hz, 1 Hz, and 10 Hz. The hysteresis at switching polarization is displayed by the shape of polarization loops changing with the field amplitude from bi-angles to quasi-saturated loop patterns of a high degree of rectangularity. The ratio of remnant polarization to maximum polarization as function of field amplitude is presented. Thermal behaviour of the coercive field and the half-width of polarization loops is …

Anti-inflammatory Effects of South American Tanacetum vulgare

1998

Abstract In recent years the role of phenolic compounds and sesquiterpene lactones, particularly parthenolide, in the anti-migraine and anti-inflammatory effects of Tanacetum parthenium (Asteraceae) has attracted much attention. However, the closely-related cosmopolitan species T. vulgare has remained outside the mainstream of research in this field. After treating the aerial parts of T. vulgare with dichloromethane and methanol, and applying conventional column and thin-layer chromatographic techniques, it was possible to isolate from the moderately lipophilic fractions the principles responsible for the anti-inflammatory activity of this plant against the mouse-ear oedema induced by 12-O-…
