Apparatus for the inspection of cargo containers for nuclear materials comprising one or more arrays of modules comprising grounded, closed conductive tubes filled with an ionizing gas mixture such as, but not limited to, Argon:CO2. A first method infers host location based on the DNS names of the host of interest or other nearby network nodes. This object is met, according to the invention, in that a gas preparation unit is provided for defined control of the temperature and pressure of a tin-containing work medium and the flow thereof into the vacuum chamber in gaseous state. In particular, capillary suction capacity is measured in terms of a member’s capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section. The stored data is then used in an assessment of a project. For instance, some implementations may generate a user interface data structure representing a user interface, the user interface data structure being generated based at least in part on state data and imperative programming code.
