A complete mathematical description of oscillatory Couette flows within the framework of kinetic theory is not available in the literature. Motivated by this and their vast engineering applications, we present a parametric study of time-periodic oscillatory Couette flows using the unsteady direct simulation Monte Carlo ~DSMC! method. Computations are performed as a function of the Knudsen ~Kn! ...

This paper provides evidence of heterogeneous treatment effects on trade for six different types of exchange rate regime transitions, utilizing data on 218,643 country-pair-year observations all together. Previous research mainly focused on the currency union effect on trade and widely assumed that country-pairs with identical observable characteristics receive the same effect. We test the hypo...

In order to study the effect of zeolite and biologic fertilizers application under different irrigation regime on yield and quantitative traits in sugar beet, a research project was conducted according split-split plot experiment based on randomized complete block design with four replicates. The main factor included irrigation regime at two levels (Normal and stress), sub factor included zeoli...

Reform of the bus sector has been occurring in many countries. One matter central to these reform initiatives is the establishment of a value for money (VM) regime to ensure that operators deliver to the market the best possible service levels consistent with stakeholder needs, and especially with the objectives of government. A key underlying feature of VM is identifying the benefit to society...

In countries where citizens have strong grievances against the regime, attempts to address these grievances in the course of daily life are likely to entail high costs coupled with very low chances of success in any meaningful sense; consequently, most citizens will choose not to challenge the regime, thus reflecting the now well-known collective action problem. When a regime commits electoral ...

Transitions from state socialism generated a startling array of early economic outcomes, ranging from severe economic crises to steady economic growth, and igniting debates about the causal role of policy choices, institutional design, and initial economic circumstances. We depart from prior explanations in two ways. First, we distinguish between causes of initial recessions and causes of varia...

Material moduli of the cytoskeleton (CSK) influence a wide range of cell functions. There is substantial evidence from reconstituted F-actin gels that a regime exists in which the moduli scale with frequency with a universal exponent of 3/4. Such behaviour is entropic in origin and is attributable to fluctuations in semiflexible polymers driven by thermal forces, but it is not obvious a priori ...

Using the lattice Boltzmann multiphase model, numerical simulations have been performed to understand the dynamics of droplet formation in a microfluidic cross-junction. The influence of capillary number, flow rate ratio, viscosity ratio, and viscosity of the continuous phase on droplet formation has been systematically studied over a wide range of capillary numbers. Two different regimes, name...

The injection of gas in a liquid-saturated granular bed gives rise to a wide variety of invasion patterns. Many studies have focused on constrained porous media, in which the grains are fixed in the bed and only the interstitial fluid flows when the gas invades the system. With a free upper boundary, however, the grains can be entrained by the ascending gas or fluid motion, and the competition ...
