We describe a method which uses a rather detailed model of coronal loop hosting a siphon flow as a diagnostic tool to interpret solar UV and X–ray observations in selected bands and lines. We apply the method to investigate the deviations from ionization equilibrium induced by stationary plasma flows confined in coronal loops and their effects on the UV and EUV emission lines observed by the in...

The lack of anticipated engagement in e-business by small to medium sized enterprises (SMEs), who are an important contributor to economic activity, is of increasing concern to governments and service providers alike. This paper explores the use of a conceptual framework which includes theoretical contributions from ICT adoption by SMEs, strategic networks and inter-organisational systems and e...

We present an analysis of time series data acquired with the SUMER spectrograph on SoHO in coronal hole regions, being particularly interested to find the fast solar wind origins as low as possible in the solar atmosphere. We study the temporal evolution of the magnetic network as seen in different layers in the transition region (TR). Our results indicate that, in lines originating from low to...

This paper introduces and empirically explores the concept of an organizational reference group: the set of people an individual perceives as belonging to his or her work environment that defines the social world of work in which he or she engages. The concept is proposed to fill a gap in studies of social context. Scholars tend only to infer, not identify, the people an individual is aware of ...

The Coronal Diagnostic Spectrometer (CDS) onboard the SOHO satellite has been used to obtain movies of quiet Sun regions at disc centre. These movies were used to study brightness variations of solar features at three different temperatures sampled simultaneously in the chromospheric He I 584.3 Å (2·104 K), the transition region O V 629.7 Å (2.5·105 K) and coronal Mg IX 368.1 Å (106 K) lines. I...

We compare the substructures of the 1997 February 07 coronal mass ejection (CME) observed near the Sun with a corresponding event in the interplanetary medium to determine the origin of magnetic clouds (MCs). We find that the eruptive prominence core of the CME observed near the Sun may not directly become a magnetic cloud as suggested by some authors and that it might instead become the ”press...

Dynamical processes are progressively introduced in stellar evolution. In this framework, the Sun is a very specific case where both models and observations have been developed in parallel during the last decade in order to progress on our present insight of solar like stars. In this poster I show the recent progress done on both sides for the rotation of the radiative zone. The present knowled...

We examine spectral time-series of two lowerchromospheric lines (N i 1319 Å and C ii 1335 Å) observed with the SUMER instrument on the SOHO spacecraft. We point out differences between (intensity and velocity) power spectra of network and internetwork regions and argue that the behaviour resembles that of Ca ii power spectra. No significant phase differences are found between the intensities of...

Teleworking is the key to a more flexible design of working time and places of work on the way to the modern information society with a knowledge oriented growth of economy. The rapid development of electronic networking systems such as Internet and the penetration of ISDN-based applications have demonstrated the enormous potential of technical facilities for new employment models. This paper d...
