The green tube-like structures are small arteries called arterioles running through the brainstem . An especially important class of objects in GAP are those whose underlying mathematical abstraction is that of a structured set , for example a group , a conjugacy class , or a vector space . This report links to the individual data files as well as other relevant sources , such as eprints , and possibly external structure databases , and presents an interactive visualisation of the derived structure ( Figure 2 ) . This happens frequently ; many kernel structures are located by way of an embedded list_head structure or kobject , for example . Employers must not place construction loads on a concrete structure or portion of a concrete structure unless the employer determines , based on information received from a person who is qualified in structural design , that the structure or portion of the structure is capable of supporting the intended loads . To allow a cut-and-paste operation to work when structures are different , source elements must be transformed to become consistent with the target structure . The increasing use of high-throughput instruments , like those provided by the EPSRC National Crystallography Service ( NCS ) at the University of Southampton ( http://www.soton.ac.uk/~xservice/ ) , means that not all structures are now able to be published in a timely manner ( e.g ., Allen , 2004 ; Hursthouse , 2004 ) . Footnote ( 2 ) Where protective structures are provided , ventilation and confinement of product should be considered . Programs can be edited using a structured editor with full graphics layout capabilities .
