The effect of transportation on blood cortisol and catecholamine levels, lymphocyte glucocorticoid receptor (GR) and beta-adrenergic receptor (beta-AR) concentrations was investigated in calves. Blood samples were collected from 24 six-month-old calves before departure (T(0)), on arrival (T(1)), and at 24 h (T(2)) and one week (T(3)) after arrival. Animals(More)
Susceptibility of sheep to scrapie, a transmissible spongiform encephalopathy of small ruminants, is strongly influenced by polymorphisms of the prion protein gene (PRNP). Breeding programs have been implemented to increase scrapie resistance in sheep populations; though desirable, a similar approach has not yet been applied in goats. European studies have(More)
Postmortem observations of 37 cattle from an outbreak of contagious bovine pleuropneumonia (CBPP) in north Italy in 1993 were made at the abattoir, where samples of lung and tracheobronchial lymph node tissues were taken for culture and identification of Mycoplasma mycoides subspecies mycoides (MmmSC), immunohistochemistry with the peroxidase(More)
The experiment was designed to evaluate the effects of housing system and short-term transportation on the pituitary and adrenal response and on blood progesterone concentrations of beef cattle. Since the use of steroid hormones in farm animals has been banned in the EU (Council Directive 96/22/EC), it seems important to study the possible modifications in(More)
— The paper considers the properties a Multi-Robot System should exhibit to perform an assigned task cooperatively. Our experiments regard specifically the domain of RoboCup Middle-Size League (MSL) competitions. But the illustrated techniques can be usefully applied also to other service robotics fields like, for example, videosurveillance. Two issues are(More)
—We investigate the problem of how to make a multi-robot system performing a cooperative task by inducing a set of emergent actions. We model the environment dynamics by considering some parameters that express the ability of each robot to perform its task. Thus, the members of a group of robots become aware of their ability to realize some tasks by simply(More)
