This paper presents a new discretization method to solve the population balance equation (PBE) for batch and unsteady/steady-state continuous perfectly-mixed systems. The numerical technique is valid for any size change ...

We discuss a model derived from the Williams population balance equations, written in mixture form, to represent water-in-oil emulsions undergoing separation by gravity. The model includes the treatment of the disperse ...

We analyse a recent application of homotopy perturbation method to some models for population balances. We show that the only result of the application of this implementation of the perturbation approach is the Taylor ...

Introduction: Institutionalized older adults have fewer opportunities to participate in daily living activities and tasks in an independent manner, with greater deleterious effects on the physiological losses inherent to ...

A population balance model based on a detailed literature review is used to describe coagulation and flocculation kinetics as well as the time evolution of aggregate size distribution in a turbulent shear flow simultaneously ...

The Human Leukocyte Antigen (HLA) loci are extremely well documented targets of balancing selection, yet few studies have explored how selection affects population differentiation at these loci. In the present study we ...

Currently environmental pollution is one of the most important factors affecting natural populations and acting as a strong selective pressure. Therefore, identifying genes and their alleles implied in population ...

Little is known about brain aging or dementia in nonindustrialized environments that are similar to how humans lived throughout evolutionary history. This paper examines brain volume (BV) in middle and old age among two ...

Particle size distribution (PSD) is a key factor in size reduction processes. These processes are widely used worldwide and in the Colombian industry. However, they represent a high energy consumption process, which requires ...
