BACKGROUND Research about collaboration within teams of learners in intensive care is sparse, as is research on how the learners in a group develop into a team. The aim of this study was to explore the collaboration in teams of learners during a rotation in an interprofessional education unit in intensive care from a sociocultural learning perspective. METHODS Focused Ethnographic methods wer...

During the latest Neoproterozoic to Mid-Cambrian time (580–505 Ma ago), the Earth underwent significant changes in palaeogeography that included rifting of a possible supercontinent and the near simultaneous formation of a second, slightly smaller supercontinent. It is against this tectonic backdrop that the Cambrian radiation occurred. Although the general tectonic setting during this interval...

The first aerosol indirect effect over a clean, northern high-latitude site was investigated by determining the aerosol cloud interaction (ACI) using three different approaches; ground-based in situ measurements, combined ground-based in situ measurements and satellite retrievals and using only satellite retrievals. The obtained values of ACI were highest for in situ ground-based data, clearly ...

The last two decades have witnessed a dramatic growth in interest in the interaction between economic activity and geophysical variables. A major hurdle for current research is the complete disjunction of socioeconomic and geophysical data. The present study describes the results of the GEcon project, which has developed a geophysically based data set on economic activity. The G-Econ data prese...

Adjustments to data observed at pairs of climate stations have been recommended to remove the biases introduced by differences between the stations in time of observation, temperature instrumentation, latitude, and elevation. A new network of climate stations, located in rural settings, permits comparisons of temperatures for several pairs of stations without two of the biases (time of observat...

A general Recursion-Transform method is put forward and is applied to resolving a difficult problem of the two-point resistance in a non-regular m × n cobweb network with an arbitrary longitude (or call radial), which has never been solved before as the Green's function technique and the Laplacian matrix approach are difficult in this case. Looking for the explicit solutions of non-regular latt...

The aims of this paper are (1) briefly to describe the plasma devices onboard the MAGION-4 satellite, launched on 3 August 1995, of the INTERBALL project, and (2) to discuss first observations made near the magnetopause region. During the presented boundary crossings the MAGION-4 observed quasiperiodic pulses of magnetosheath-like plasma in a region of low plasma density. This region is located...

[1] At low latitudes, cirrus are ubiquitous and can be in excess of 100 C colder than the surface, limiting the amount of sunlight absorbed by the earth’s atmosphere and surface, and reducing its loss of heat. Here we present aircraft measurements within cirrus over southern Florida indicating that ice crystals have smaller sizes and are more reflective than is assumed in most current climate m...
