We propose a massless nonminimally coupled scalar field as a mechanism for stabilizing the size of the extradimension in the Randall-Sundrum I scenario. Without needing to introduce self interactions terms we obtain a potential for the modulus field that sets the size of the fifth dimension. The minumum of this potential yields appropriate values of the compactification scale for small values o...

κ-casein is a glycosilated protein belonging to a family of phosphoproteins (αs1,β, αs2,κ) that represents the major protein component in mammalian milk. κ-casein plays an essential role in the case of micelle stabilization, determining the size and the specific biological function. in the present study, we report the characterization of the partial sequence of κ-casein promoter region in the i...

Composting is a natural process that occurs as result of microbial succession and marks the degradation stabilization organic matter in waste. The use additives during composting believed to be highly efficient, it increases production various enzymes, resulting faster rate waste degradation. converts into humus-like substance can enhance physical, chemical, biological properties soil. In this ...

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...

A complex mechanical-biological waste treatment plant designed for the processing of mixed municipal solid wastes (MSW) and source-selected organic fraction of municipal solid wastes (OFMSW) has been studied by using stability indices related to aerobic (respiration index, RI) and anaerobic conditions (biochemical methane potential, BMP). Several selected stages of the plant have been character...

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 ...

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.

We reduce the problem of proving the convergence of a randomized self-stabilizing algorithm under k-bounded policies to the convergence of the same algorithm under a specific policy. As a consequence, all k-bounded schedules are equivalent : a given algorithm is self-stabilizing under one of them if and only if it is self-stabilizing under any of them.
