The results of the chemical transport model REM-CALGRID (RCG) were used to demonstrate the significance and impact of the proposed measures. The accuracy measures are defined in such a way that they can be used for any AQ model which is able to simulate AQ concentrations at a 1-h time ...
Since its foundation in 1918, CITIZEN has continued its pursuit of the essence of timekeeping, always challenging new possibilities, while pushing the boundaries of watchmaking technology as a true manufacture d’horiogerie. The Cal.0100 boasts an accuracy of ±1 second during a span of one yea...
The goal of this study was to determine the accuracy of a culture technique and the invA-gen-based PCR, for the detection of Salmonella spp. From caecal samples from slaughtered pigs. For this purpose a Bayesian approach was used. Two hundred and three pigs were used. Animals were grouped...
