A bstract local flavour symmetry acting on the quarks of Standard Model can automatically give rise to an accidental global U(1) which remains preserved from sources explicit breaking up a large operator dimension, while it gets spontaneously broken together with symmetry. Such non-fundamental symmetries are often endowed mixed QCD anomaly, so that strong CP problem is solved via axion mechanis...

Retail stores often offer discounts on purchases of large amounts of meat. Some of the meat is prepared the same day, and some is stored for later use. This study evaluates the effect of retail packaging, freezing and thawing on the quality of beef patties. Loosely ground beef was retail-packed in: (1) highly permeable wrap, and (2) high oxygen MAP. The meat was subsequently refrigerated at 4°C...

In four experiments, rats received flavour aversion conditioning followed by extinction. The flavour was then subjected to retardation and summation tests. Experiment 1 showed that reacquisition of an extinguished flavour aversion was retarded with respect to the performance shown by rats for whom the flavour was novel. No retardation was found, however, with respect to a control group that had...
