Econometric Analysis of Milk Value Chain

This article deals with the basic analysis of price transmission in the milk agri-food chain. The analysis is aimed at deriving the fundamental relationships between milk prices at the individual levels of the chosen vertical. The results are then validated with the use of statistical hypotheses testing. From the derived single equation models, it is clear that there is a strong difference in the leverage of individual factors influencing the price at different levels of the milk value chain. The results were elaborated within the research intention IVZ MSM 6046070906Agri-food Chain, Milk, Price Transmission, Statistical Test, Demand and Price Analysis, Financial Economics, Research Methods/ Statistical Methods, GA, IN,

In situcharacterization of floc morphology by image analysis in a turbulent Taylor-Couette reactor

Flocculation of bentonite was performed in a turbulent Taylor–Couette reactor under various shear rates. Image processing enabled to determine various morphological characteristics of individual flocs. Not only their mean values but also their distributions were studied under various hydrodynamic conditions. Relevant properties were selected. The temporal evolution of radius of gyration and circularity distributions was monitored during the flocculation process. Although size and shape are obviously correlated, this article points out that their dependency to hydrodynamics is different, showing that flocs of similar sizes produced under different hydrodynamic conditions exhibit different shapes. The sizes are calibrated by the turbulence as the double radius of gyration is close to Kolmogorov microscale, whereas the circularity seems correlated to the rotation speed. © 2014 American Institute of Chemical Engineers AIChE J, 60: 2389–2403, 201
