Microminiature Joule-Thomson refrigerators have been fabricated using a novel photolithographic process. We discuss the scaling laws which allow one to design these refrigerators of arbitrarily small size and the fabrication process which makes it possible to mass produce them at low cost. Commercial systems are now available for operation with N2 gas from ambient to 80 K with a refrigerator capacity of 250 mW. Lower temperature operation using H2 and He is presently under development. The use of these devices for microcalorimetry, material research Cheap Nike Air Force 1 Mid and other applications is reported. This article describes the experiences of two US teacher groups and their lesson study work. Their stories illustrate some of the dynamics and promise of teacher change spurred by lesson study. The first case is primarily about teacher efficacy, as a group of teachers discover through lesson study that their planning and work can have an impact on student Nike Air Max White Uk engagement in the classroom in a way that they had not realized. The second case is about one teacher's struggle with the move from isolation to collaboration, illustrating the tension between autonomy and collaboration that often occurs during such a transition.
