Imaging and spectroscopy of the knots, clumps, extended arcs in complex ejecta VY CMa confirm a record high mass-loss events over past few hundred years. Hubble Space Telescope/Space Telescope Spectrograph numerous small knots close to star allow us measure their radial velocities from strong K i emission determine separate motions, spatial orientations, time since ejecta. Their ages concentrat...

Vertebral pathology has long been a useful criterion for anthropologists in the assessment of activity patterns, stress, and general health of extinct peoples. This method of analysis, however, has never been applied to the peoples of the Nebraska Great Plains. This study is the first to concentrate on the in­ digenous Native Americans of this region, examining the spinal pathology present in t...

Defining historic grazing pressures and rangeland management is vital if early landscape threshold crossing and long–term trajectories of landscape change are to be properly understood. In this paper we use a new environmental simulation model, Búmodel, to assess two contrasting historical grazing landscapes in Mývatnssveit Iceland for two key periods—the colonization period (ca. Landnám, A.D. ...

the modern infirmary is the evolutional product of the dialectic interface between medical theories at each time and the outcome of their application in clinical practice. the infirmary as we know it today did not exist during antiquity, but the different precursors of the modern hospital emerged as a result of the interaction between medical theory and practice. during antiquity the hippocrati...

studying the prominent iranian-islamic scientific texts of middle ages in the field of ophthalmology may play a role in recognizing the science of traditional ophthalmology and its crucial diagnostic and therapeutic points. the most important and reliable resources in the context of ophthalmology belong to iranian scientists. this study collects these references and provides their relative equi...

In this paper we describe the development of the Church Experience Scale (CES) that allows us to measure visitor experience in historic churches, both with and without multimedia guides and other technologies. This study was carried out with 272 respondents at three historic churches in York, UK. Respondents for this study were visitors to these churches who were asked to complete a questionnai...
