Amaranth seeds contain oil with important nutritional properties, in particular, because of the presence essential fatty acids, high content minerals, vitamins, lysine and squalene. In this study, kinetics supercritical fluid extraction from three amaranth seed varieties has been investigated. The average was 58.2 g/kg, ranging 54.6 to 61.1 g/kg depends on varieties, while squalene ranged 3.3 3...

in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...

The performance of sulfate-reducing permeable reactive barriers (PRB) used for the treatment of acid-mine drainage is critically affected by kinetics of cellulose decomposition and substrate production, as well as by kinetics of sulfate reduction and methanogenesis. When biofilm models are considered, the rate of substrate diffusion into the biofilm also affects performance. In this regard, res...

Mathematical modeling is an essential tool for the comprehensive understanding of cell metabolism and its interactions with the environmental and process conditions. Recent developments in the construction and analysis of stoichiometric models made it possible to define limits on steady-state metabolic behavior using flux balance analysis. However, detailed information on enzyme kinetics and en...
