One of the disputed consequences of global economic integration is the possible effect that foreign economic liberalization exerts on social cohesion. Proponents of commercial liberalism see stabilization as an indirect consequence of growing economic interdependence, while globalization critics are much more skeptical. They expect, at least during the liberalization process, destabilizing effe...

The adoption of a common currency has fostered European economic integration and provided many European countries with an e¢ cient tool to reduce in‡ation and …nancial volatility. It is well understood, however, that a single monetary policy also opens a stabilization gap at national level, relative to an ideal benchmark in which output gaps and marginal costs are e¢ ciently stabilized in each ...

Abstract Waste treatment using thermal technologies, such as incineration, leads to the production of pollutants and wastes, including fly ash (FA). Fly contains heavy metals (HMs) other contaminants can potentially pose high risks environment negatively impact health safety. Consequently, stabilizing prior either use or landfilling is crucial. The toxicity through metal leaching be assessed te...

Thermostable chitinases are useful for industrial and biotechnological applications. This paper reports the stabilization of chitinase from Serratia marcescens B4A through rational mutagenesis. Changing of Ser 390 to Ile in S. marcescens. The stabilization was enhanced through entropic stabilization by reduction of the loop length and also by increasing of the beta chain length. With this repla...

aims: in biological wastewater treatment processes, a large amount of sludge is produced. stabilization of sludge is essential before disposal because of the risks to human health and environment. therefore, selecting an appropriate process for stabilization this sludge may efficiently decrease risks. the aim of this study was to examine the compound efficiency of the advanced fenton and ozonat...

today, environmental crisis and loss of natural resources are the principle causes of the creation of environmental management systems. the optimal management of natural resources requires the assessment and classification of ecological and environmental potentials. using this method, the abilities and restrictions of resources can be recognized, and their future trends can be predicted. nebka ...

economists were interested in economic stabilization policies as early as the 1930’s but the formal applications of stability theory from the classical control theory to economic analysis appeared in the early 1950’s when a number of control engineers actively collaborated with economists on economic stability and feedback mechanisms. the theory of optimal control resulting from the contributio...

Maintaining spanning trees in a distributed fashion is central to many networking applications and selfstabilizing algorithms provide an elegant way of doing it in fault-prone environments. In this paper, we propose a self-stabilizing algorithm for maintaining a spanning tree in a distributed fashion for a completely connected topology. Our algorithm requires a node to process O(1) messages on ...

In this paper, we address the unison problem. We consider the self-stabilizing algorithm proposed by Boulinier et al. We exhibit a bound on the step complexity of its stabilization time. In more details, the stabilization time of this algorithm is at most 2Dn + (α + 1)n + (α− 2D)n steps, where n is the number of processes, D is the diameter of the network, and α is a parameter of the algorithm.
