drought stress is a major factor limiting crop production. investigation of physiological characteristics related to drought tolerance and crop production may be useful in selecting drought tolerant cultivars as well as in improving crop yield. two drought tolerant (azar2 & back cross roshan) and two drought susceptible (marvdast & shiraz) cultivars were investigated in both greenhouse and fiel...

The operational stability and continuity are key production characteristics of actual refinery processing units, which plays important role to safe and efficient production. While few literatures have given a sufficient and comprehensive expression of such characteristics. In view of the problem, this paper discussed refinery operations optimization based on operational stability and continuity...

stability studies play a critical role in assuring product quality at all points in the vaccine life cycle and havea major impact on the success of immunization programs worldwide. the purpose of stability study isdetermination of the vaccine quality under the variety of environmental factors and to establish a re-testperiod or a shelf life and recommended storage conditions. in this study thre...

Pistachio paste is produced from ground roasted kernel. This study focused on the influence of the milling process on colloidal stability, rheological behavior and color of pistachio paste. The colloidal stability of pistachio paste samples increased with a reduction of particle size from 31.4 to 15.10µm. The Herschel-Bulkley model was found to be the best model to describe the flow behavior of...

This paper presents a voltage stability constrained optimal power flow that is expressed via a bilevel programming framework. The inner objective function is dedicated for maximizing voltage stability margin while the outer objective function is focused on minimization of total production cost of thermal units. The original two stage problem is converted to a single level optimization problem v...

Conservative agriculture is considered as an alternative to tackle the need for increased agricultural production based on sustainable agriculture activities with the aim of increasing production and product stability along with preserving the environment. Tillage is one of the most important factors affecting soil structure. Selection of appropriate tillage systems varies according to the cond...

In this paper numerical results are reviewed ([13]) that demonstrate that common second-order operator-splitting methods can exhibit instabilities when integrating the Brusselator equations out to moderate times of about seven periods of oscillation. These instabilities are manifested as high wave number spatial errors. In this paper we further analyze this problem and present a theorem for sta...
