The influence of laterality on mastitis incidence in dairy cattle - preliminary study
During summer (June to August) of continental weather conditions treated mastitis episodes at a large Hungarian dairy farm were studied to determine the relationship between the distribution of mastitis among quarters of the udder and the lying behaviour (laterality) of the cows. There was a significant difference in laterality between cows that developed mastitis and cows that did not. Cows that developed mastitis, had an increased left laterality in lying, which was related to the increased probability of a right-sided mastitis episode. However, the effect was not significant due to the large variation in the data. At the same time, significantly more cows with clinical mastitis had a somatic cell count (SCC) higher than that of cows without clinical mastitis. While a significant correlation was found between the occurrence of treated mastitis cases and SCC ≯ 1,000,000, no statistically significant differences could be observed in milk production between the two groups

Slow, Stored and Stationary Light
Slow light has received growing interest since 1999 when the propagation velocity of light was reduced in an experiment to 17 m/s, i.e. almost 20 million times slower than in vacuum. Two years later light pulses were stopped, or more specifically stored in an atomic medium and subsequently released after some time. This provided the basis for important applications in photon-based quantum information technology. The present chapter explains what slow light is and what it is good for, how to understand the physics of it and how one can practically make light go so slow. To answer these questions, the chapter uses simple pictures, on the one hand, and supplements them with a little bit of details, on the other hand, for those who want to go slightly deeper into the field. The chapter also discusses more recent generalizations of slow light, such as stationary and spinor slow light which are interesting model system and can be used to understand more complex quantum systems
