This study based on longitudinal Zeeman effect magnetograms and spectral line scans investigates the dependence of solar surface magnetic fields on the spectral line used and the way the line is sampled in order to estimate the magnetic flux emerging above the solar atmosphere and penetrating to the corona from magnetograms of the Mt. Wilson 150-foot tower synoptic program (MWO). We have compar...

This study presents Quantitative Field Observations (QFOs) of educationally relevant affect and behavior among students at three schools using Reasoning Mind, a game-based software system designed to teach elementary-level mathematics. High levels of engagement are observed. Possible causes for these high levels of engagement are considered, including the interactive pedagogical agent and other...

This study measures pedestrian walking speeds in New Zealand to estimate the influences of mean walking speeds as these concern urban planning and pedestrian facility design. Research was conducted using field observations of walking speeds under different conditions: gradient and urban/rural townships. The data show complex interrelationships between environment, personal characteristics of pe...

in this research work the classification of the southern coasts of the caspian sea is performed using sedimentary and morphodynamic indices. this includes field study of morphodynamic characteristics of the shore structures. field measurements include in situ samplings of sediments and actual observations of structures on site. these field activities were done along six transects in the dry coa...

Direct measurements of magnetic fields in low-mass stars of spectral class M have become available during the last years. This contribution summarizes the data available on direct magnetic measurements in M dwarfs from Zeeman analysis in integrated and polarized light. Strong magnetic fields at kilo-Gauss strength are found throughout the whole M spectral range, and so far all field M dwarfs of...

We report on prompt and afterglow observations of GRB 000615 detected by BeppoSAX. The study of the high-energy prompt event is presented along with the search for its X–ray and optical after-glow. Spectral fits seem to suggest a temporal evolution of the GRB prompt emission. We possibly find evidence for intrinsic N H (at 90% confidence level) and for a transient spectral emission feature arou...
