Direct control of protein level enables rapid and efficient analyses of gene functions in crops. Previously, we developed the RDDK-Shield1 (Shld1) system in the model plant Arabidopsis thaliana for direct modulation of protein stabilization using a synthetic small molecule. However, it was unclear whether this system is applicable to economically important crops. In this study, we show that the...

We use the thermodynamic model introduced by Aptekar’ and Ponyatovskiy for the – transformation in cerium metal to study the properties f plutonium metal. The model describes the – transformation in Pu and explains the minimum in the melting versus pressure curves for both aterials. Ga stabilization of the -phase of Pu is explained in terms of a first order transition between the two phases. Th...

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...

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 ...

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.
