Various studies on the interaction of immobilized mammalian fibrinogen and fibrin monomers with some fibrinogen derivatives demonstrated the presence of two sets of polymerization sites in the mammalian fibrinogen molecule. We obtained the same results while investigating the fibrinogen molecules of other classes of vertebrates /Pisces. Amphibia. Aves/. Despite significant differences among their subunit structures, all of them contain polymerization sites homologous to mammalian counterparts. Moreover, due to great functional similarity, fibrinogen or fibrin monomers of the analyzed species of Pisces. Amphibia. Aves and Mammalia interacted in a specific way with immobilized pig fibrin monomers or fibrinogen, respectively. Using these pig affinity adsorbents, fibrinogen and fibrin monomers of different vertebrates were isolated directly from plasma and analyzed by SDS polyacrylamide gel electrophoresis. Polypeptide compositions of eluted proteins were identical to those obtained for corresponding fibrinogen preparations isolated by cold-ethanol fractionation method. It appears to indicate that the nature of polymerization sites in vertebrate fibrinogens is alike.

There are conflicting results as to whether preschool children categorize artifacts on the basis of physical or functional similarity. The present study investigated the effect of the relative distinctiveness of these dimensions in children's categorization. In a physical-distinctive condition, preschool children and adults were initially asked to categorize computer-animated artifacts whose physical appearances were more distinctive than their functions. In a function-distinctive condition, the functional dimension of objects was more distinctive than their physical appearances. Both conditions included a second stage of categorization in which both dimensions were equally distinctive. Participants in a control condition performed only this stage of categorization. Adults in all conditions and stages consistently categorized by functional similarity. In contrast, children's categorization was affected by the relative distinctiveness of the dimensions. Children may not have a priori specific beliefs about how to categorize novel artifacts, and thus may be more susceptible to contextual factors.

Introduction. The article is devoted to the presentation of the results of the study of metaphorization and the study of metaphorical terms, widely represented in the English terminology of veterinary medicine. The purpose of the article is to represent the features of the anthropomorphic metaphorical name in the English terminology of veterinary medicine. Materials and methods of research. The study of metaphorization as a way of forming English veterinary terms was conducted by us on the basis of lexicographic data recorded in English terminological dictionaries of veterinary medicine. Results of the research. The analysis of lexicographic material allowed to identify four donor domains that served as a source of metaphorical names in the terminology of veterinary medicine: HUMAN, LIVING ORGANISM, NATURAL FACT, ARTIFACT. Conceptual analysis of metaphorical terms of veterinary medicine revealed that one of the most productive metaphors used in the creation of terminological units is anthropomorphic. In anthropomorphic metaphorization, the names are transferred from the donor domain HUMAN to the recipient domain VETERINARY. The article attempts to consider the cognitive basis of anthropomorphic metaphor as one of the mechanisms of creation of veterinary terms in English. Based on the theory of conceptual metaphor, it was found that the sources of anthropomorphic metaphor are the biological characteristics of people, the names of body parts and properties of a living organism. Semantic groups of metaphorical terms formed on the basis of cognitive transfer of tokens related to the structure of the human body, its behavior, inherent qualities, life and way of life in the field of veterinary medicine based on external or functional similarity between donor and recipient domains are considered. Сonclusions. Thus, the study allows us to conclude that the terms-metaphors occupy a certain niche in the terminology of veterinary medicine in English and ensure their effective functioning in the language of veterinarians. Conceptual analysis of metaphorical terms of veterinary medicine revealed that one of the most productive is anthropomorphic metaphor. As a result of anthropomorphic metaphorization, new terms of veterinary medicine are formed on the basis of cognitive transfer of tokens that relate to the social characteristics of a person that determine his appearance, behavior or condition, in the field of veterinary medicine on the basis of external or functional similarity between donor and recipient domains.
