The Law Enforcement community possesses a large, but informal, community memory with respect to digital forensics. Large, because the experiences of every forensics technician and investigator contribute to the whole. Informal because there is seldom an explicit mechanism for disseminating this wisdom except “over the water cooler”. As a consequence, the same problems and mistakes continue to r...

At the University of Twente, a 14.5 K hydrogen-based sorption cooler is under development. It can be used as a stand-alone 14.5 K cooler, or as a precooler, e.g., in combination with a 4 K heliumbased sorption cooler. The advantage of sorption coolers is the absence of moving parts and, as a result, their vibration-free operation and, potentially, a very long life. A 4.5 K helium-based sorption...

The thermal response characteristic of a hybrid cooler that is charged with a “dry” solid-solid phase change compound is evaluated. A mathematical model that simulates the performance of a cooler/heat storage unit is formulated. A prototype heat sink that incorporates heat storage using a “dry” PCM is tested, and used to benchmark the simulation model. Different heating and cooling strategies a...

Construction of a compact 2.4 Tm Cooler Injector synchrotron (CIS) to injection intense polarised proton and deuteron beams into the IUCF 3.6 Tm electron cooled storage ring (Cooler) is complete. Beam commissioning began in 1997 with unpolarized H strip injection and progressed to the extraction of 210 MeV protons from CIS and the injection of 10 protons at 200 MeV into the Cooler for experimen...

The ocean mixed layer response to a tropical cyclone within and immediately adjacent to the Gulf of Mexico Loop Current is examined. In the first of a two-part study, a comprehensive set of temperature, salinity, and current profiles acquired from aircraft-deployed expendable probes is utilized to analyze the three-dimensional oceanic energy evolution in response to Hurricane Lili’s (2002) pass...

We measured temperature variation in a free-ranging ectotherm by attaching microdataloggers to the carapaces of 34 painted turtles (Chrysemys picta) in a farm pond located in Davidson, NC. Water and mud temperatures (Tw) were simultaneously monitored. We successfully recorded external shell temperature (Ts) in 18 turtles from September 2001–April 2002 and 23 turtles from April 2002–October 2002...
