materials and methods a multivariate variance experiment was performed. to assess the effect of essential oil, nisin and the incubation temperature on growth probability (log p%) of s. typhimurium and s. aureus, four concentrations of c. cyminum l. essential oil (0, 15, 30 and 45 µl/100 ml), three concentrations of nisin (0, 0.5 and 1.5 µg/ml) and three storage temperatures (10, 25 and 35°c) we...

consider the random walk among n places with n(n - 1)/2 transports. we attach an exponential random variable xij to each transport between places pi and pj and take these random variables mutually independent. if transports are possible or impossible independently with probability p and 1-p, respectively, then we give a lower bound for the distribution function of the smallest path at point log...

1. The survival and penetration of Salmonella enterica serovar Enteritidis (SE) inoculated on the eggshell was examined upon storage for up to 20 d at real-life conditions (15 to 25 degrees C and 45 to 75% relative humidity (RH)). 2. Penetration was assessed by emptying the egg contents and filling the eggs with a selective medium that allowed visualising Salmonella growth on the inside of the ...

This study aimed to investigate the growth kinetics of Staphylococcus aureus on rice cake and to determine the shelf life based on the probability model of the increase in S. aureus contamination on rice cake. Secondary models were developed based on the growth parameters derived from the Baranyi model at constant temperatures (15, 25, 35, and 45°C). External validation was then conducted using...

We deterministically compute a ∆+1 coloring in time O(∆5c+2 ·(∆5)/(∆1) + (∆1) + log∗ n) and O(∆5c+2 · (∆5)/∆ + ∆ + (∆5) log∆5 log n) for arbitrary constants d, and arbitrary constant integer c, where ∆i is defined as the maximal number of nodes within distance i for a node and ∆ := ∆1. Our greedy algorithm improves the state-of-the-art ∆+1 coloring algorithms for a large class of graphs, e.g. g...
