Esta noção carece de maior especificação. Com efeito, é necessário identificar e classificar os agentes económicos, os objectos económicos e a...
Aqueous two-phase micellar systems (ATPMS) are micellar surfactant solutions with physical properties that make them very efficient for the extraction/concentration of biological products. In this work the main proposal that has been discussed is the possible applicability and importance of a novel oscillatory flow micro-reactor (micro-OFR) envisaged for parallel screening and/or development of industrial biopr...
This paper describes a user-friendly software for the calculation of general piping system networks composed of virtually any parallel and series pipe arrangement. Solution of the network is made with recourse to the iterative method of Hardy Cross. Solution is provided for pressure and flow-rate in each branch. Dimensioning problems, where pump characteristics or a pipe diameter are sought for achieving a pre-...
