The accuracy of protein biosynthesis rests on the high fidelity with which aminoacyl-tRNA synthetases discriminate between tRNAs. Correct aminoacylation depends not only on identity elements (nucleotides in certain positions) in tRNA (1), but also on competition between different synthetases for a given tRNA (2). Here we describe in vivo and in vitro experiments which demonstrate how variations...

this article discusses the cession of contract. after presenting the definition of cession of contract, this base on contractual position and has an independent identity. by dividing the cession of contract in to executive and judiciary and contractual, their conditions are investigated. finally the effects of cession of contract discussed.

In this paper we highlight issues related to measuring ethnicity and ethnic identity. We base our discussion on an extensive review of the literature and an intensive consultation process undertaken as part of the development of the ethnicity focused strand of a major new UK panel study, Understanding Society. We conclude that ethnic identity is a multi-dimensional concept and its ideal measure...

A base for a commutative semigroup (S,+) is an indexed set 〈xt〉t∈A in S such that each element x ∈ S is uniquely representable as ∑t∈F xt where F is a finite subset of A and, if S has an identity 0, then 0 = ∑n∈ xt . We investigate those commutative semigroups or groups which have a base. We obtain the surprising result that Q has a base. More generally, we show that an abelian group has a base...

This paper presents the theoretical framework for a project in which we will design, develop and test a personal identity profile that can contribute to an improved mediated collaboration environment for virtual project teams. The profile aims to foster interpersonal trust by enabling better and quicker estimations on trustworthiness. We here describe the mental model for trustworthiness estima...

The task of Coreference (CO) had its origins in Semeval, an attempt after MUC-5 to define semantic research tasks that needed to be solved to be successful at generating scenario templates. In the MUC evaluations, only coreference of type identity was marked and scored [3]. The following example from MUC-7 (New York Times News Service) illustrates identity coreference between "its" and "The U.K...

OBJECTIVE Facial allotransplantation is fast becoming a reconstructive option for severely disfigured individuals, but it is still in experimental stage. Facial allotransplantation will be considered fully ethical only when it addresses the recipient's identity concerns. There exist no such studies that quantify and predict identity changes following change in geometry of underlying facial skel...
