The retention of solutes in the ice formed in a falling-film freeze concentrator (multi-plate freeze-concentrator) was analysed. Solutions of fructose, glucose and sucrose and a simulated juice with initial concentrations ...

We consider the following stationary Keller-Segel system from chemotaxis

The progressive freeze concentration of sucrose solutions was tested. The effect of the initial concentration of the solution (C0), the temperature of the refrigerant (T), and the stirring speed (ω) on the final concentration ...

We consider the following singularly perturbed Neumann problem

In this work we deal with the following nonlinear Schrödinger equation: {−^ϵ2Δu+V(x)u=f(u)in ^RNu∈^H1(^RN),(Formula presented.) where N≥3, f is a subcritical power-type nonlinearity ...

The interactive effects of N (6, 9, 12 and 15 mmol L-1) and K (3, 5, 7, and 9 mmol L-1) concentrations in nutrient solutions were evaluated on bell pepper grown in a coconut-coir substrate and fertilized without drainage. ...

AIM AND OBJECTIVE: To evaluated the tissue dissolution of sodium hypochlorite (NaOCl) and peracetic acid (PA) solutions at different concentrations, with or without ultrasonic agitation. MATERIALS AND METHODS: The following ...

We consider the singularly perturbed Neumann problem epsilon(2)Delta u - u + up = 0, u > 0 in Omega, partial derivative u/partial derivative v = 0 on partial derivative Omega, where p > 1 and Omega is a smooth and bounded ...
