Today's software platforms that support the construction of agent systems in accordance with the FIPA specifications essentially provide enabling infrastructure services, and are still far away from adequately rendering support to current methodologies and theories for building agent systems, especially when social concepts play a significant role.(More)
On the assumption that the ability to discriminate facial expressions has adaptive value to infants during early social exchanges, ethologically based theorists have argued that this ability is innate. Guided by this perspective, we investigated the ability of infants, 4-6 months old to recognize and discriminate facial expressions of anger, fear, and(More)
The perception of and memory for faces, with or without emotional content, were studied in 43 patients with temporal lobe epilepsy who had undergone unilateral resection of the hippocampus and the amygdala and in 43 healthy participants for comparison. Each participant performed four tasks from the Florida Affect Battery (Facial Discrimination, Affect(More)
Although neutral faces do not initially convey an explicit emotional message, it has been found that individuals tend to assign them an affective content.

Using functional magnetic resonance imaging in 21 healthy participants, we focus this study on(More)
The pharmacokinetics of the biliary elimination of oxytetracycline (OTC) and tissue concentrations in certain organs were studied in 10 Leghorn hens. The animals were anaesthetized using xylazine/ketamine administered by the intramuscular (i.m.) route and were immobilized for right laparotomy. Both bile ducts were cannulated and a dose of 20 mg/kg of(More)
This paper describes a proposal of a language called Link which has been designed to formalize and operationalize problem solving strategies. This language is used within a software environment called KSM (Knowledge Structure Manager) which helps developers in formulating and operationalizing structured knowledge models. The paper presents both its syntax(More)
Azithromycin is the first of a class of antimicrobial agents designated azalides. The aim of the present study was to investigate the disposition pharmacokinetics of azithromycin in goats and determine its bioavailability. A cross-over study was carried out in two phases separated by 30 days. Azithromycin was administered at a single dose of 20 mg/kg body(More)
