Device for treatment of a gas flow having at least one body that is adapted to cause a conversion in the composition of the gas. In various embodiments, the musical output is either a music score, or an analog or digital audio file. Data from the preliminary image is used to identify features of interest in the object or to perform other image analyses that do not require a high-resolution image. The housing body and the terminal mounting block define a cavity with the at least one terminal projecting into the cavity from the terminal mounting block. The second structural component is placed in abutting relationship with the first structural component, covering the first recess and resting atop the second leg of the bracket, with the second leg of the bracket positioned in the second recess. The method for measuring jawbone mineral density includes: obtaining a jawbone X-ray image using a support device for jawbone; defining a region of interest from the obtained jawbone X-ray image; and measuring jawbone mineral density from the defined region of interest.
