None of this could have happened The Editor’s offering without our authors submitting their work for consideration. Without them there is, of course, no journal. Not unnaturally All our readers will have a basic understanding of the Ideal there is often pressure to publish in major mainstream Gas Law and of diabatic and adiabatic phenomena, either journals, but it is important that EUBS and SPUMS members from their school-days physics or from their diving/diving support their own specialty journal as much as they possibly medicine training.1,2 Those working in hyperbaric chambers can. Only by doing so will DHM continue to grow in stature experience thermodynamic affects every day with changes in and Impact Factor. Whatever one thinks about IF, it is temperature − warming with compression and cooling with often the yardstick by which researchers’ publications are decompression − and pressure − the fall in pressure after measured by their employing institutions. A concerted effort compression if the operator does not ‘top up’), as the heat to support DHM is still needed from you all. generated from compression dissipates into the heat sink of the chamber’s metal walls.
