Artemia salina L.is an important model organism for the world ecosystem, which is very sensitive, easily available, allows to work in laboratory environment, used toxic effect studies, and gives safe results. This study was designed evaluate of water extract fresh underground parts some species five geophyte genera (Arum rupicola var. virescens (Stapf) P.C. Boyce, Cyclamen cilicium Boiss. &...

A common approach in designing relational databases is to start with a universal relation schema, which is then decomposed into multiple subschemas. A good choice of subschemas can be determined using integrity constraints defined on the schema, such as functional, multivalued or join dependencies. In this paper we propose and analyze a new normal form based on the idea of minimizing overall st...

Given the fact that relational and object-relational databases are the most widely used technology for storing data and that XML is the standard format used in electronic data interchange, the process of converting relational data to XML documents is one that occurs frequently. The problem that we address in this paper is an important one related to this process. If we convert a relation to an ...

THE design and use of laser photocoagulators for the treatment of pathological conditions in the eye has been described by Ingram, Manson, and Smart (1965) and Ingram (1966). When lesions need to be made close to the fovea, extremely precise positional control of the lesion is necessary. Involuntary eye movements (Boyce, 1967; Ditchburn and FoleyFisher, 1967) and human reaction times become imp...

Development of a suitable measure of quality of movement, or gross motor performance, for children with cerebral palsy is a complex undertaking. A variety of conceptual, methodological, and practical issues inherent in such a project are discussed in this article. We report on the methodology used in the planning and construction of the Gross Motor Performance Measure. The measure has been deve...

We present a three-dimensional nonlinear finite element formulation for dielectric elastomers. The mechanical and electrical governing equations are solved monolithically using an implicit time integrator, where the governing finite element equations are given for both static and dynamic cases. By accounting for inertial terms in conjunction with the Arruda–Boyce rubber hyperelastic constitutiv...
