the effect of zinc nano-particles (zn- nano- complex) on bull sperm quality after freeze-thawing process studied. ejaculates collected from four holstein bulls twice a week. on the day of semen collection, four ejaculates were pooled and diluted with bioxcell extender containing 0, 10-6, 10-5, 10-4, 10-3, 10-2 molar of zinc nano-complex and frozen. after thawing, sperm motility and motion param...

The paper reports the ongoing functional specification of a virtual archaeology system. Taking into account the goals of ISO standards MPEG-7 and SEDRIS, we have summarized methodologies from related IT fields (visualization, multimedia, HCI and VR) relevant for virtual archaeology system functionality. One part of the ideas has been used to specify the functionality of a particular system for ...

Supramolecular Polymers with Orthogonal Functionality Report Title Supramolecular polymers with orthogonal interactions are of broad interest, and reports on such materials with multifunctional stimuli-responsive behavior are rare. Polymer blends based on a poly(ethylene-co-butylene) core (PEB) terminated with either 2-ureido-4[1H]-pyrimidinone (UPy) hydrogen-bonding motifs (UPy-PEB-UPy) or 2,6...

To support a vast set of user requirements, flexibility and extensibility are essential features of a metasystem architecture. We present an execution model, the Reflective Graph and Event Model, and demonstrate its use in Legion, an object-oriented metasystem project. Reflective features of the model are key in meeting our design goals of flexibility and extensibility.

Autonomic computing aims to provide self-management and adaptation in the implementation of complex (large, heterogeneous, distributed) systems over time. Such adaptations must be stable, in the sense of maintaining the system’s high-level goals across environmental changes, which may lead to functionality loss. In this paper we present FReSH, a decentralised component-based framework which mai...

For the last few years, Peer-to-Peer systems were created with the purpose of distributing information across a very large set of hosts. The scalability demands of such systems lead to the design of Distributed Hash Tables algorithms[1, 2, 3, 4], which are capable of locating an object anywhere on the system given a key value using logarithmic (or constant) message hops while maintaining logari...
