p. atlantica subsp. kurdica, with the local name of baneh, is a wild medicinal plant which grows in kurdistan, iran.  the identification of resistance gene analogs holds great promise for the development of resistant cultivars. a pcr approach with degenerate primers designed according to conserved nbs-lrr (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (r) gene...

In this paper,  we determine necessary and sufficient Tauberian conditions under which convergence in Pringsheim's sense of a double sequence of fuzzy numbers follows from its $(C,1,1)$ summability. These conditions are satisfied if the double sequence of fuzzy numbers is slowly oscillating in different senses. We also construct some interesting double sequences of fuzzy numbers.

medicinal use of the opium poppy (papaver somniferum l) has ancient history, but the isolation of morphine was not described until the early nineteenth century. morphine is the most important alkaloid of opium poppy in the last 50 years. in the morphine pathway has been reported to generate morphine in this species, codm has a crucial role as the gene coding the enzyme responsible for demethyla...

Background and Objective: Secretory extracellular Phospholipases are generally involved in hydrolysis of extracellular phospholipids and thus providing nutritive source of carbon, nitrogen, and phosphate. However, intracellular phospholipases perform metabolic functions and adjust biologic activities. Synthesis of phospholipases in different pathogenic microorganisms and their mode of action in...

ابزارهای مولکولی روشهای بسیار دقیق برای تنوع زیستی هستند. روش issr (inter-simple sequence repeats amplification ) روشی نسبتاً نوین برای بررسی گونه های نزدیک به هم می باشند. در ایران، جنس eremias پراکندگی وسیعی در زیستگاه ها متنوع از دشتی، ماسه ای و نیمه صحرایی دارند. همچنین این جنس تنوع گونه ای زیادی دارد بطوریکه تنها در ایران 16 گونه از آن معرفی شده است. به منظور بررسی روابط خویشاوندی بین گونه ...

Optimisation of stacking sequence for composite plates under slamming impact loads using genetic algorithm method is studied in this paper. For this purpose, slamming load is assumed to have a uniform distribution with a triangular-pulse type of intensity function. In order to perform optimisation based on the genetic algorithm method, a special code is written in MATLAB software environment. T...

In this article, we consider pair frames in Banach spaces and   introduce Banach pair frames. Some various concepts in the frame theory such as frames, Schauder frames, Banach frames and atomic decompositions are considered as   special kinds of (Banach) pair frames.  Some frame-like inequalities  for (Banach)  pair frames are presented. The elements that participant  in the construction of (Ba...

Let be a sequence of weakly negative dependent (denoted by, WND) random variables with common distribution function F and let be other sequence of positive random variables independent of and for some and for all . In this paper, we study the asymptotic behavior of the tail probabilities of the maximum, weighted sums, randomly weighted sums and randomly indexed weighted sums of heavy...

  The problem of lot sizing, sequencing and scheduling multiple products in flow line production systems has been studied by several authors. Almost all of the researches in this area assumed that setup times and costs are sequence –independent even though sequence dependent setups are common in practice. In this paper we present a new mixed integer non linear program (MINLP) and a heuristic me...
