گونه های مختلف جنس بلوط سطوح وسیعی را در جنگلهای شمال، ارسباران و زاگرس می پوشانند. رده بندیهایی که تاکنون در داخل کشور در مورد جنس بلوط انجام شده فقط بر مبنای ویژگی های ریخت شناسی برگ و میوه بوده، اما با توجه به گوناگونی این صفات، ناجوربرگی و نیز تولید دورگ های احتمالی، اختلاف نظر در این زمینه زیاد است. امروزه در تمام نقاط دنیا سعی می شود که به کمک میکروسکوپ الکترونی از صفات ثابتی مانند ویژگی ...

let $g$ be a finite group. we construct the prime graph of $ g $,which is denoted by $ gamma(g) $ as follows: the vertex set of thisgraph is the prime divisors of $ |g| $ and two distinct vertices $ p$ and $ q $ are joined by an edge if and only if $ g $ contains anelement of order $ pq $.in this paper, we determine finite groups $ g $ with $ gamma(g) =gamma(l_3(q)) $, $2 leq q < 100 $ and prov...

Abstract We introduce most of the concepts for q -Lie algebras in a way independent base field K . Again it turns out that we can keep same Lie algebra with small modification. use very similar definitions all quantities, which means proofs are similar. In particular, quantities solvable, nilpotent, semisimple algebra, Weyl group and chamber identical ordinary case = 1. The computations sample ...

In the recent decade that research in IR methods for Intellectual Property domain has increased. The rst e orts in observing how information retrieval is done in patent domain were done with the series of Nist workshops (see for example [2]). Lately, more workshops and conferences are dedicated to bringing together IR and IP specialists [3,8]. In 2008, the Irf obtained the agreement to coordina...

The authors compared personality correlates of creative achievement and wise performance in middle-age women of a longitudinal study. In Q-sort descriptions, originality and ambition were particularly salient in creative individuals, whereas meaningmaking and benevolence were salient in wise individuals. Inventory measures of openness, unconventionality, ambition, and autonomy at age 21 predict...

This paper presents the HDG learning algorithm, which uses a hierarchical decomposition of the state space to make learning to achieve goals more efficient with a small penalty in path quality. Special care must be taken when performing hierarchical planning and learning in stochastic domains, because macro-operators cannot be executed ballistically. The HDG algorithm, which is a descendent of ...
