Although it is the focus of a growing number of scholars in communication, computer science, psychology, and cognitive science, there is little agreement concerning the nature and measurement of presence. Marvin Minsky (1980) used the term "telepresence" to refer to teleoperation technology that provides the user with a "remote presence" in a different location via feedback systems that allow h...

background: bone marrow mesenchymal stem cells (mscs) are one of the undifferentiated multipotential cell sources of human body. methods: mscs have the capacity to form a variety of cell types, especially chondrocytes and osteocytes. learning about responses of mscs to external milieu and chemical factors such as ph could recommend new approaches for preparation of suitable scaffolds for bone a...

Abstract: The present study deals the theoretical modeling aspects of coupled conductive and radiative heat transfer in the presence of absorbing, emitting and scattering gray medium within two-dimensional square furnace including two flames. The gray radiative medium is bounded by isothermal walls which are considered to be opaque, diffuse and gray. The well known discrete ordinate method (DOM...

Government agencies and other national and international institutions are asked to perform forecasts over the medium term. In particular, the EU Stability and Growth Pact contains the obligation to formulate stability programmes over four years, covering a general economic outlook as well as the projected development of public fi nances. However, the current practice of performing medium-term e...

OBJECTIVE Depressive symptoms seem to pose a risk factor for mortality among patients on dialysis. It is currently unknown whether the association is only short-lived and whether associations over time depend on specific causes of mortality. METHODS In a prospective nationwide cohort study, 1528 patients with end-stage renal disease starting on dialysis completed the Mental Health Inventory. ...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...
