Let T be the genealogical tree of a supercritical multitype Galton–Watson process, and let 3 be the limit set of T, i.e., the set of all infinite self-avoiding paths (called ends) throughT that begin at a vertex of the first generation. The limit set3 is endowed with the metric d(ζ, ξ) = 2−n where n = n(ζ, ξ) is the index of the first generation where ζ and ξ differ. To each end ζ is associated...
the purpose of this study was to investigate the relationship between family functioning and marital adjustment humor couples are due to the nature and objectives of the research and application of methods for its implementation correlation was used. the study population consisted of all the couples in the city who uses random cluster sampling of 200 students were selected as sample. data from ...
Introduction: Family function has been changed by the couplechr('39')s simultaneous employment and presents particular problems ahead of them. The children dimension is one of the dimensions that strongly influences the family function. The purpose of this study was to extract the lived experience of the dual-career couple from the influence of the children dimension on family functioning. Met...
طی بررسی هائی که جهت جمع آوری و شناسائی فون کنه های بادام در استان چهار محال و بختیاری در سال های 88-1387 انجام شد مجموعا، 23 گونه متعلق به 18 جنس و 8 خانواده جمع آوری و شناسائی شد که 2 گونه برای اولین بار از ایران معرفی گردید که با (*) مشخص شد، و تعداد 3 گونه برای اولین بار در دنیا شناسائی و توصیف گردید که با علامت (**) مشخص شده اند. لیست گونه های گزارش شده بر اساس طبقه بندی راسته و خانواده ب...
We construct a family of spaces with “nice” structure which is universal in the class of all compact metrizable spaces of large transfinite dimension ω0, or, equivalently, of small transfinite dimension ω0; that is, the family consists of compact metrizable spaces whose transfinite dimension is ω0, and every compact metrizable space with transfinite dimension ω0 is embeddable in a space of the ...
A family of connected graphs G is said to be a family with constant metric dimension if its metric dimension is finite and does not depend upon the choice of G in G. In this paper, we study the metric dimension of the generalized Petersen graphs P (n, m) for n = 2m + 1 and m ≥ 1 and give partial answer of the question raised in [9]: Is P (n, m) for n ≥ 7 and 3 ≤ m ≤ bn−1 2 c, a family of graphs...
anxiety is one common disorder during childhood. in curing anxiety disorders, there are different types of psychological remedies, pharmotherapy, family therapy, and music therapy that can improve the individual’s anxiety, but we need some other remedies to improve social and emotional relationship and interactions. considering the importance of curing the anxiety disorders, the effect of sand ...
The dimension D(S) of a family S of subsets of n = (1,2, . . . . n> is defined as the minimum number of permutations of n such that every A E S is an intersection of initial segments of the permutations. Equivalent characterizations of D(S) are given in terms of suitable arrangements, interval dimension, order dimension, and the chromatic number of an associated hypergraph. We also comment on t...
زنجرک های fulgoromorpha، حشراتی با طیف میزبانی وسیع هستند که از آوندهای آبکش موجود در ریشه، طوقه و ساقه گیاهان علفی وگاهی آوند آبکش برگ های گیاهان چوبی تغذیه می کنند و در جمعیت های بالا می توانند خسارت های فراوان و جدی را به محصولات کشاورزی وارد نمایند. منطقه ی گرگان مشتمل بر دو شهرستان گرگان و آق قلا در استان گلستان، در شمال شرقی ایران از اقلیم های متنوعی شامل شش نوع اقلیم خشک، نیمه خشک، مدیتر...
