Airway management skills are essential for healthcare providers within military and civilian settings. To maintain competency in these skills, it is crucial for the provider to have opportunities for review and retraining. Virtual airway training or telementoring can be an effective means to fulfilling these requirements for healthcare providers located in remote sites. The projection of high quality imagery to far forward locations is essential for health care practitioners in the provision of telemedicine and distance training. The Storz C-CAM was developed to interface with existing endoscopy equipment to facilitate implementation of telemetric devices in remote locations. This work describes the use of the Storz C-CAM in providing medical device training to deployed medical personnel at a far forward location.

Previous Office of Inspector General (OIG) reviews found that Durable Medical Equipment (DME) Medicare Administrative Contractors (MACs) did not ensure that lower limb prosthetic claims met the coverage requirements in local coverage determinations (LCDs). LCDs are decisions by DME MACs on whether to cover a particular service in accordance with section 1862(a)(1)(A) of the Social Security Act (the Act) and are published to provide guidance to the public and the medical community. In response to one of OIGs reviews, on March 5, 2012, the Centers for Medicare & Medicaid Services (CMS) issued a Technical Direction Letter (TDL) directing the DME MACs to develop claim-processing edits for all requirements in LCDs for lower limb prostheses. Noridian Healthcare Solutions, LLC (Noridian), is one of the DME MACs. This review is part of a series of reviews to determine the compliance of DME MACs with LCD requirements for lower limb prostheses. The objective of this review was to determine whether Noridian processed and paid claims for lower limb prostheses according to LCD requirements for the period January 1, 2010, through December 31, 2011.

CO2 lasers use gas as the active laser medium. CO2 lasers are preferred over other lasers such as excimer lasers because they are more reliable, efficient, robust, and easier to operate. They are used for cutting and welding in industries such as Manufacturing, Automotive, Electronics, Healthcare, and Telecommunication. Their superior performance, compact size, high output power, and durability make them the most prominent among all the gas lasers developed.

An experimental campaign was undertaken at the Von Karman Institute, Belgium, aimed at investigating the sliding doors inlet starting mechanism for a hypersonic scramjet inlet. This campaign provides the first step upon a much larger inlet starting investigation, with the results providing a backbone for comparison to future 2D and 3D transient RANS numerical studies. A scaled 2D representation of the SCRAMSPACE-I geometry was constructed, with two steel 3.2mm thick doors extending upstream from the inlet leading edge at an angle of 20 degrees. After achieving steady flow conditions, the doors were then retracted via a pneumatic piston and cabling system, with the resulting flow phenomena captured via visualization as well as quantitative instrumentation. The test campaign was undertaken in the H3 Wind Tunnel Facility, which provided a jet at Mach 6 at various reservoir pressures, with variance in Reynolds number used to simulate changing altitude conditions. Due to limitations with regards to tunnel blockage and diffuser placement, a scaling factor of 5.1 was applied to the model geometry proportionally in both the x and y directions. Successful inlet starting was achieved at conditions simulating flight at an altitude of approximately 29 km. Schlieren visualization techniques were employed, showing that supersonic conditions were indeed obtained in the inlet for approximately 32 flow lengths. Senflex thin film arrays, located on the inner surfaces of the inlet, captured the transient heat flux progression at different locations along the inlet. These profiles accurately captured the phenomena observed via the Schlieren imaging, in particular the propagation of shock structures into the inlet during the inlet starting procedure. Stanton number distributions along both arrays were extracted and showed a close comparison to those expected from numerical simulations reconstructed test flow conditions, which lends credibility to the integrity of the heat flux results.

Injection molding machines are used to produce various plastic products by injecting materials such as nylon, polystyrene, ethylene, polycarbonate, and polypropylene into the mold through the injection molding process. They help in the fast production of plastic parts with reduced waste and low cost. Injection molding of thermosetting plastics and thermoplastics is done with these machines. The machines are used mainly in the Packaging, Automotive, and Healthcare industries. They are also used for various applications in the Electronics and Construction industries.

Penetration of projectiles was measured for hemispherical and conical nose shapes penetrating granular media. Targets were beds of Ottawa sand and Eglin sand. Projectiles were rigid metals. Experimental parameters that were varied included velocity (from 300 to 600 m/s), nose shape, sand density, and scale (from 5 mm to 20 mm). Strong evidence for scale effects is found: 5 mm diameter projectiles are less effective penetrators than 12.5, 15, or 20 mm diameter penetrators.
