1. Overview In the following we wish to highlight the design and implementation concepts of a non-standard database system (NDBS) called PRIMA and its provision for object orientation. Non-standard database applications such as CAD/CAM, VLSI design, and knowledge-based systems require adequate modeling facilities for their application objects for various reasons [H~.88b]. Data models dedicated ...

Computational grids and other heterogeneous, large-scale distributed systems require more powerful and more flexible authorization mechanisms to realize fine-grained access-control of resources. Computational grids are increasingly used for collaborative problem-solving and advanced science and engineering applications. Usage scenarios for advanced grids require support for small, dynamic worki...

Mesotoga strain PhosAc3 was the first mesophilic cultivated member of the order Thermotogales. This genus currently contain two described species, M. prima and M. infera. Strain PhosAc3, isolated from a Tunisian digestor treating phosphogypsum, is phylogenetically closely related to M. prima strain MesG1.Ag.4.2(T). Strain PhosAc3 has a genome of 3.1 Mb with a G+C content of 45.2%. It contains 3...

Early Cambrian Pseudooides prima has been described from embryonic and post-embryonic stages of development, exhibiting long germ-band development. There has been some debate about the pattern of segmentation, but this interpretation, as among the earliest records of ecdysozoans, has been generally accepted. Here, we show that the 'germ band' of P. prima embryos separates along its mid axis dur...

The logic of actual obligation The logic of An alternative approach to deontic logic. In this paper we develop a system of deontic logic (LAO, the"; logic of actual obligation) with a.rathep limited scope: we are, only interested in obligations as far as they: are; relevant for deciding: what: actions-actually ought to be done in a particular situation, given some normative system, N. In fact w...

This paper focuses on the interpretation of the Italian approximative adverb quasi ‘almost’ by primarily looking at cases in which it modifies temporal connectives, a domain which, to our knowledge, has been largely unexplored thus far. Consideration of this domain supports the need for a scalar account of the semantics of quasi (close in spirit to Hitzeman’s 1992 semantic analysis of almost). ...

This article is concerned with the question of whether Pāli Buddhism endorses vegetarianism and therefore whether a good Buddhist ought to abstain from eating meat. A prima facie case for vegetarianism will be presented that relies upon textual citation in which the Buddha stipulates that a good Buddhist must encourage others not to kill. The claim that the Buddha endorses vegetarianism, howeve...

In Wireless Sensor Network (WSN), QoS (Quality of Service) in sensor application plays a very important role. QoS based routing is required to ensure the best use of nodes in WSN. In this paper, a comparative study of QoS based routing in Media Access Control (MAC) protocols are presented based on the traits to solve problems like prioritization, timeliness, reliability etc. The study mainly fo...

Der folgende Beitrag gibt einen Überblick über den Umgang mit Nullwerten im Molekül-Atom-Datenmodell (MAD-Modell) und dessen Implementierung PRIMA. Zunächst beschreiben wir einige der Lösungen, die im Relationenmodell für die Behandlung von Nullwerten vorgeschlagen wurden, und stellen dann den Umgang mit Nullwerten im MAD-Modell vor, wie wir ihn in PRIMA realisiert haben. Ziel ist es, den Benut...
