background and objectives: leptospirosis is considered to be the most widespread zoonotic disease in the world and can infect a wide range of animals. although the prevalence of clinical leptospirosis in cats is low, they are probably exposed to leptospires excreted by wild life, rodents etc. this study was performed to determine the serologic reaction of cats to leptospires and their importanc...

background: leptospirosis is a worldwide zoonosis causedby leptospira interrogans. leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. objectives:the aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...

The reasons for emergent behaviour in microscopic models of artificial life are still not well understood. One issue that recurs in the ALife literature is that of the role spatial locality plays in governing emergent properties. We have developed a highly localised microscopic animat model based on interacting species of predators and prey. We report on experiments with open and closed boundar...

The paper deals with reciprocity relations in bianisotropic electromagnetic materials. Conditions for reciprocity are expressed and discussed in connection with macroscopic and microscopic level of consideration and with space-time symmetry properties of media. Newly is the connection between microscopic and macroscopic treatment to reciprocity theorem analyzed namely with respect to composed b...
