Abstract: Systems for visualization and management of a clinical study have a processor, an input device, a database storing data related to the clinical study, and a visit schedule interface. The data have a study visit schedule. The study visit schedule has nodes and a track having a step sequence. Each node has a node position and node attributes. The node position has a node track identifying the track and a node step. The data may also have a visit travel policy and the node attributes may have a visit policy label associated with the visit travel policy.

Abstract: Systems for visualization and management of a study have an input device, a user interface, controls, and a database storing a visit schedule about the study and visit data about a participant. Visit schedule has a first node and second node. The participant visit data has a current visit associated with the first node. The user interface visually associates the first node with a first graphic and with a current visual attribute, and the second node with a second graphic. Responsive to the controls, the user interface associates the second node with the current visit and visually associates the current node graphic with the second node. Visit schedule may have a third node selected from a jump, cycle, exit, and other nodes. The third node is associated with an occurred visit in the visit data, and the user interface can visually associate an occurred visual attribute with the third node.

Abstract: A system for visualization and management of participants in studies having a graphical user interface (GUI), a database (DB) storing studies data, visit schedules, travel policies, sites data, and participants data having a first participant in a first study. The GUI has controls including system control, data controls (being one or more of a travel policy control, visit schedule control, and participant control), navigation control associated with the study, and selection control associated with the participant. The GUI responsive to using the controls can a) switch GUI views; b) receive and display participants data; c) receive and display visit schedule and travel policy associated with the first participant and with the first study; d) receive input data from the input device and cause the DB to update the studies data, participants data, travel policies, and visit schedules with the input data. DB may store a second participant.

Abstract: A mortar ammunition round which contains at least three fragment producing regions covered by a threadably removable aluminum cowling. Detachment of the cowling provides access to several of the fragment producing regions which are located on a removable cup device. A different cup device may then be selectively inserted and the cowling replaced, forming a new mortar round of different select performance capabilities.
