An overview of asymmetric synthesis in continuous flow and microreactors is presented in this review. Applications of homogeneous and heterogeneous asymmetric catalysis as well as biocatalysis in flow are discussed.

A digital filtering algorithm for continuous base flow separation is compared to physically based simulations of base flow. It is shown that the digital filter gives comparable results to model simulations in terms of the multiyear base flow index when a filter coefficient is used that replicates the watershed-specific time delay of model simulations. This way, the application of the heuristic ...

We consider semi-continuous network flow problems, that is, a class of network flow problems where some of the variables are restricted to be semi-continuous. We introduce the semi-continuous inflow set with variable upper bounds as a relaxation of general semi-continuous network flow problems. Two particular cases of this set are considered, for which we present complete descriptions of the co...

A time-dependent numerical simulation is performed to examine the flow separation control with action of a hybrid jet (the combination synthetic and continuous jets) over NACA23012 airfoil. The unsteady Reynolds-averaged Navier–Stokes (URANS) Spalart-Allmaras (SA) turbulence model simulate field around airfoil analyse effect jet. combined placed at point on upper surface which located 12% chord...

Babies with one pumping ventricle need a series of medical and surgical procedures in order to have an adequate blood flow to the lungs and consequently to survive and grow. The Fontan operation is usually the final stage of surgeries and isolates the systemic and pulmonary circulation. This study focuses on the second stage of surgeries, in which the superior vena cava (SVC) is connected direc...

An Enhanced genetic algorithm (EGA) which is used to the solution of the optimal load flow (OPF) with both continuous and discrete control variables. The tenuous control variables modeled are unit active power outputs and generator–bus voltage magnitudes while the discrete ones are transformer – tap settings and switchable shunt devices. A number of functional operating constraints, such as bra...

Both the continuous and batch transesterification of linseed oil were examined in order to maximize the fatty acid methyl esters (FAME) yield. The continuous process was conducted in a packed bed reactor using calcium oxide as a heterogeneous catalyst. In addition, the impact of two variables, namely the molar ratio of methanol to oil and the flow rate (ml/min), on the FAME yield were stu...
