Use of Desirability Function Method in Optimization of Regeneration and Callus Induction of <i>Alhagi camelorum</i>

引用

American Journal of Plant Sciences 2014年第3期5卷 268-274页

作者： Maryam Honari hossein askari Mahmood Khosrowchahli Biotechnology Department of Plant Breeding Faculty of Agriculture and Natural Resources Tehran Azad University Science and Research Branch Tehran Iran Department of Biotechnology Faculty of New Technology Engineering Shahid Beheshti University Tehran Iran Department of Plant Breeding Faculty of Agriculture and Natural Resources Tehran Azad University Science and Research Branch Tehran Iran

In this study, the desirability function approach was used to simultaneously optimize multiple factors. The variables evaluated were combinations of growth regulators, media and organs in affecting the organogenesis of Alhagi. In the first step of this study, various experiments were carried out in order to optimize the callus induction and its growth. The highest rate of callus induction was achieved from the leaf segment on MS medium supplemented with 3 mg·l-1 BAP + 6 mg·l-1 NAA. Moreover, the highest rate of regeneration was recorded on MS medium supplemented with those 4 mg·l-1 BAP using for leaf segments. The optimized condition of roots induction per shoot was observed in the 1/4 MS medium without activated charcoal and supplemented with 0.25 mg·l-1 IAA. The well rooted plantlets were acclimatized and successfully established into soil where 70% plantlets were survived. The data indicate that media, BAP, and NAA levels may be manipulated to increase or decrease quality factors chosen.

REMOVAL OF MERCURY FROM WATER USING POLYPYRROLE AND ITS COMPOSITES

引用

Chinese Journal of Polymer Science 2007年第4期25卷 393-397页

作者： hossein Eisazadeh Faculty of Chemical Engineering University of MazandaranP.O.Box 484BabolIran

One of the suitable methods for removing heavy metals from water is by using surface adsorption process. In this paper, the preparation of polypyrrole and its composites as adsorbents are discussed and the capability of separating mercury from water is investigated. The results indicated that the polypyrrole and its composites are able to remove mercury from aqueous media. Furthermore the adsorption percentage is related to the surface morphology, type of additives and its concentration.

Thermodynamics of 4D dS/AdS Gauss–Bonnet black holes according to consistent gravity theory in the presence of a cloud of strings

By looking at the Lovelock theorem one can infer that the gravity model given by[1]cannot be applicable for all types of 4D Einstein–Gauss–Bonnet(EGB)curved *** reason for this is that in 4D space-time,the Gauss–Bonnet invariant is a total derivative and hence it does not contribute to gravitational ***,the authors of[2]presented an alternative consistent EGB gravity model instead of[1]by applying a break-of-diffeomorphism *** this work,we use the alternative model to produce a de Sitter(dS)/Anti-de Sitter(AdS)black hole metric and then investigate its thermodynamic behavior in the presence of a cloud of Nambu–Goto *** derivations show that the resulting diagrams of pressure vs specific volume at a constant temperature are similar to that for a van der Waals gas/fluid in an ordinary thermodynamic system in the d S sector but not in the Ad S *** this,we infer that the black hole participates in the small-to-large black hole phase transition in the dS background,while it exhibits a Hawking–Page phase transition in the AdS *** the latter case,an evaporating black hole eventually reaches an AdS vacuum space because of its instability.

Correlation of the mean activity coefficient of aqueous electrolyte solutions using an equation of state

引用

Chinese Journal of Chemical Engineering 2016年第10期24卷 1456-1463页

作者： Seyed hossein Mazloumi Chemical Engineering Department Faculty of EngineeringFerdowsi University of Mashhad

Accurate calculation of thermodynamic properties of electrolyte solution is essential in the design and optimization of many processes in chemical industries. A new electrolyte equation of state is developed for aqueous electrolyte solutions. The Carnahan-Starling repulsive model and an attractive term based on square-well potential are adopted to represent the short range interaction of ionic and molecular species in the new electrolyte EOS. The long range interaction of ionic species is expressed by a simplified version of Mean Spherical Approximation theory （MSA）. The new equation of state also contains a Born term for charging free energy of ions. Three adjustable parameters of new eEOS per each electrolyte solution are size parameter, square-well potential depth and square-well potential interaction range. The new eEOS is applied for correlation of mean activity coefficient and prediction of osmotic coefficient of various strong aqueous electrolyte solutions at 25℃ and 0.1 MPa. In addition, the extension of the new eEOS for correlation of mean activity coefficient and solution density of a few aqueous electrolytes at temperature range of 0 to 100℃ is carried out.
