Bacillus cereus is a foodborne pathogen causing food safety issues due to the formation of difficult to eliminate spores and biofilms.The objective of this study was to investigate the occurrence of B.cereus (conducted as part of monitoring in 2017-2018) and the presence of a toxin gene in strains isolated from retail products (pastries/cakes; vege
A novel photonic approach to generating a frequency-quadrupled millimeter-wave (mm-wave) signal with a tunable phase shift is proposed and demonstrated.Two second-order optical sidebands are generated by using a Mach-Zehnder modulator (MZM) that is biased at the maximum transmission point and an optical notch filter.A polarization-maintaining fiber
Colour reconstructions have provided new insights into the lives of dinosaurs and other extinct animals, by predicting colouration patterns from fossilised pigment-bearing Front End Cover organelles called melanosomes.Although these methods have become increasingly popular, only a small number of dinosaurs have been studied using these techniques,
Fragmentation alters landscape structure and its relationship with organisms, where movement is one of the most affected processes.Movement choices are influenced by a cost and benefit evaluation, associated particularly to risks of predation and access to new resources.We analyzed the effect of matrix type on matrix-transfer success of a bird, Pyr
