Aortic Injury From High-Speed Deceleration Against a Lap Belt in a 10-year-Old
The American Surgeon™, 2023Traumatic aortic injuries in children and adolescents are rare, and even more rare are blunt traumatic injury to the abdominal aorta in this population. Therefore, there are few reports discussing the presentation and repair of such injuries, especially within the pediatric population.

High-speed nanometer lapping photonics elements
SPIE Proceedings, 2005This paper discusses some problems about nanometer lapping photonics elements. The solid abrasives high speed lapping method and the theory of lapping tool wearing uniformly are used in machining photonics elements. It makes workpiece machined surface roughness reach to Ra0.88nm, flatness reach 19nm. That not only realizes nanometer machining, but also

High Speed Chemical Image Sensor With Digital Laps System
Proceedings of the International Solid-State Sensors and Actuators Conference - TRANSDUCERS '95, 1996A high speed two-dimensional surface photovoltage (SPV) sensing system based on a digital data processing was developed and applied to an in-situ monitoring of chemical images. The SPV signal generated by a scanning light spot was directly memorized in a computer and signal integration of all measurement points was carried out in parallel in allocated ...

High-speed chemical imaging system based on front-side-illuminated LAPS
Sensors and Actuators B: Chemical, 2013Abstract The chemical imaging sensor is a semiconductor-based chemical sensor that can visualize the spatial distribution of specific ions on the sensing surface. The conventional chemical imaging system based on the light-addressable potentiometric sensor (LAPS), however, required a long time to obtain a chemical image, due to the slow mechanical ...
