The genus Elaeagnus (Elaeagnaceae) has been introduced in Iran by one or two species, i. e. E. angustifolia and E. orientalis . The species are widely cultivated trees, but native in a few localities. They are extremely variable in shape of leaves and fruits. Fruits used to be eaten highly and as they have variable tastes, the preferred ones have been subject to selection in the course of time....
The goal of the present research was to determine the relationship between Eysenck's "E" personality dimensions and a selection of metaphorical concepts. Researches in the past have emphasized personality and linguistic components in literal language. The present research investigated metaphor as a part of figurative language, and its relation with the two personality dimensions. The initial sa...

Previous studies on negative selection of T cells to sheep erythrocytes in irradiated mice showed that CBA (I-Ak,I-Ek) (kk) T cells comprise two subgroups of cells restricted by I-A (A alpha-A beta) and I-A/E (E alpha-E beta) molecules. Selection of the I-A/E-restricted by I-A (A alpha-A beta) and I-A/E (E alpha-E beta) molecules. Selection of the I-A/E-restricted subset requires that the donor...

Combinatorial auctions are an important e-commerce application where bidders can bid on combinations of items. The problem of selecting the best bids that cover all items, i.e., the Winner Determination Problem (WDP), is NP-hard. In this paper we consider the time constrained variant of this problem, that is the Bid Evaluation Problem (BEP) where temporal windows and precedence constraints are ...
We propose the Hierarchical Product Classification (HPC) framework for the purpose of classifying products using a hierarchical product taxonomy. The framework uses a classification system with multiple classification nodes, each residing on a different level of the taxonomy. The innovative part of the framework stems from the definition of classification recipes that can be used to construct h...
We present estimates of the e ciency for nding QSOs as a function of limiting mag nitude and galactic latitude From these estimates we have formulated a target selection strategy that should net QSOs in the north galactic cap with an average of bers per plate not including bers reserved for high redshift quasars With this plan we expect of the targets to be QSOs The North Galactic Cap is divide...
