This is an introductory course into some aspects of the physics of granular materials. Three theoretical questions are looked into more detail corresponding to the 3h of the course: I present some statistical models to describe the shape of a heap under impact and present a way to calculate the...

A gas kinetic method for simulating ideal fluids based on the BGK equation is described. The method is extended to model nonideal fluids. The method developed is used to simulate systems described by a Cahn–Hilliard equation coupled to a fluid equation. The results of simulations of binary...

In the present work we derive hydrodynamic equations for the infinite, rarified, smooth, non-homogeneous spherical granular gas. The long-time behavior of these equations is analyzed and we show that the diffusive modes become negligible compared to the propagating modes of the system. This...

We investigate several means of coupling between a sonoluminescing bubble and an applied magnetic field. Recent experiments show a strong quadratic dependence between the forcing pressures required for stable sonoluminescence and magnetic field amplitude. However, all coupling mechanisms...

Shallow groundwater with high arsenic concentrations from naturally occurring sources is the primary source of drinking water for millions of people in Bangladesh. It has resulted in a major public health crisis with as many as 70 million people possibly at risk. The International Atomic Energy...

Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic...

Current debates on threats to social integration in times of multiple crises call for a better understanding of the relationship between socioeconomic inequality and sociocultural value conflicts. The aim of this article is to (re)introduce the concept of social milieus as a promising approach...

This paper aims to show that economic theory has become ‘desocialised’ and separated from social theory through the adoption of individualistic methods and neglect of social relations and structures. A historical overview traces how the social content of economic theory has diminished,...
