Abstract. Stellar rotation influences our understanding of stellar structure and evolution, binary systems, clusters etc. and therefore the benefits of a large and highly accurate database on stellar rotation, obtained by GAIA, will be manifold. To study the prospects of GAIA measurement of projected rotational velocities vrot sin i, we use synthetic stellar spectra to simulate the determinatio...

A Salmonella enterica serovar Typhi gene that is selectively up-regulated upon bacterial invasion of eukaryotic cells was characterized. The open reading frame encodes a 298-amino-acid hydrophobic polypeptide (30.8 kDa), which is predicted to be an integral membrane protein with nine membrane-spanning domains. The protein is closely related (87 to 94% reliability) to different transport and per...

Like most other fundamental mechanical components which form the basis of many mechanical systems, springs have existed since the Bronze Age for storage or release of energy, absorption or utilization of vibration, relaxation or absorption of impact force and when unloaded, return to the original position or to the original shape. Quality, service requirement, performance as well as durability ...

Forthcoming wireless environment is a fusion of numerous networks with diverse technologies deployed by individual operators. In such an environment, innovative network selection methodologies are required not only to provide “always best connected” service to mobile users but also to maximize network operator’s revenue. To fulfill such requirements, multiple attributes from each network are to...

The fundamental objective of supply chain management (SCM) is to integrate various suppliers to satisfy market demand. Supplier evaluation and selection is very important for establishing an effective supply chain. As a matter of fact, supplier selection consists of both qualitative and quantitative criteria, so it is considered as a multi criteria decision making (MCDM) problem. Under incomple...

ESA’s Global Astrometric Interferometer for Astrophysics (GAIA) holds the promise of mapping out the detailed phase space structure of the Galactic halo by providing unprecedented annual proper motion and parallax of 1–10μas astrometric accuracy (Gilmore et al. 1998). Unlike NASA’s Space Interferometry Mission (SIM), which will achieve similar accuracies but is a pointed instrument, GAIA will b...

P ervasive computing environments augment human thought and activity with digital information, processing, and analysis, providing an observed world that is enhanced by the behavioral context of its users. A spectrum of heterogeneous computation and communication devices aim to enhance user productivity and facilitate everyday tasks. Despite the prevalence of such devices, however, no suitable ...

We argue that tracing star formation histories with GAIA using main sequence turn-off (MSTO) point dating will mainly be effective in cases of very mild interstellar extinction (EB−V < 0.5). For higher reddenings the MSTO approach will be severely limited both in terms of traceable ages (t < 0.5 Gyr at 8 kpc; EB−V = 1.0) and/or distances (d = 2 kpc if t ≤ 15 Gyr; EB−V = 1.0), since the MSTO wil...

Gaia theory describes the life-environment system of the Earth as stable and self-regulating. It has remained at the fringes of mainstream biological science owing to historical definition problems and its apparent incompatibility with individual-level natural selection. However, various bodies of ecological and evolutionary research suggest ways in which the biosphere might tend towards stabil...
