The Role of Money in the Business Cycle

The aim of this paper is to reemphasize the money theory of exchange which is centered on the function of exchange medium of money, and make a contribution towards linearization of the quantity equation of exchange. A dynamical quantity equation is presented and an important balanced path of economic evolution is derived. To understand the business cycle we propose a hypothesis of natural cycle and driving cycle concerning the evolution of the balanced path and plentiful conclusions can be made.

The effects of solid-liquid interfacial tension on the settlement of sediment flocs

In this paper, the effects of interfacial tension between the sediment solid particle and liquid on the settlement of sediment flocs are investigated. After a discussion of mechanical and physical chemistry, we give a settling velocity expression including such dynamical information of the floc growth as interfacial tension and primary particle size \textit{etc.}. The resulting expression indicates the average settling velocity of sediment flocs increases with increasing solid-liquid interfacial tension in a form of power law and deceases with the primary particle size. We report on a general method for analyzing settling behaviors of sediment flocs under different flocculation conditions and verify the rationality of the assumption of tension-induced flocculation by fitting typical experimental data to the electrolyte concentration-dependent sedimentation model which can follow from the relationship between interfacial tension and electrolyte concentration.

A conjecture for turbulent flow

In this paper, basing on a generalized Newtonian dynamics (GND) approach which has been proposed elsewhere we present a conjecture for turbulent flow. We firstly utilize the GND to reasonably unify the two phenomenological methods recently proposed of the water movement in unsaturated soils. Then in the same way a modified Euler equation (MEE) is yielded. Under a zero-order approximation, a simple split solution of the MEE can be obtained that shows flow fluids would have a velocity field with the power-law scaling feature (power-law fluid) for the case of high Reynolds number.
