The alkaliphilic bacterium AV1934, isolated from human feces, recent has indicated novel potassium ion coupling to motility in this extremophile. We report draft sequences that will facilitate an examination of whether that coupling is part of a larger cycle of potassium ion-coupled transporters. This draft genome has 4,095 predicted genes and 4,063 predicted proteins. The whole-genome shotgun project has been deposited in Genbank under the accession no. ALPT02000000. In addition to the 
genes encoding the MotPS channel that uses either potassium or sodium coupling, two loci encoding multisubunit Mrp-type antiporters, were found. The 
AV1934 genome reveals no tripartite ATP-independent (TRAP-T family) uptake systems, a major sodium-coupled complement in the other two alkaliphiles. The AV1934 genomic data will enable us to test the hypothesis of a major role of potassium in ion coupling in this extremophile.

The ITER device is currently under construction. To fulfil its mission, it will need a set of measurement systems. These systems will have to be robust and satisfy many requirements hitherto unexplored in Tokamaks. Typically, diagnostics occupy either a removable item called a port plug, or installed inside the machine as an intricate part of the overall construction. Limited space availability has meant that many systems have to be grouped together. Installation of the diagnostic systems has to be closely planned with the overall schedule. This paper will describe some of the challenges and systems that are currently being progressed.
