Injuries involving the head and neck represent a significant proportion of sportsrelated trauma incurred by youth athletes. Approximately 6.5 % of over 2.6 million children ≤ 19 years treated for sport and recreation-related injuries in an emergency department setting between 2001 and 2009 had sustained traumatic brain injuries or concussions [1]. In this chapter, we will review the history of ...

"In an age of electronic banking and online college degrees, why hasn't the rest of the nation gone to voting on touchscreen computers? The reason is simple and resonates with the contentious debate that has yet to be resolved after at least 15 years of wrangling over the issue of electronic voting. No one has yet figured out a straightforward method of ensuring that one of the most revered dem...

This paper proposes a scheme of building in single chip microcomputer laboratory based on Proteus software simulation, Protel software to make PCB card. It proves the feasibility of scheme by analyzing some application examples. This scheme solves the problems of capital shortage for traditional single chip labs and difficulty in equipment maintenance to a certain extent.

abstract: nowadays, the non-traditional processes such as “laser, edm and awj” used for cutting high thickness sheet metal. hardox is hard and tough steel alloy and it has many industrialize applications. one best process to cut the hardox is abrasive water jet (awj) cutting.  it can cuts complex shape with high quality and accurate tolerance.  awj cutting offers certain unique benefits such as...

Equipment service environment often has a certain corrosive, accelerate equipment corrosion, affect the integrity of equipment. In order to accurately monitor micro-environment corrosion strength equipment, multi-channel quartz crystal microbalance calibration test and vibration sensor temperature supplement were carried out realize frequency-quality signal conversion improve accuracy data acqu...

Formal definitions for the components of efficiency and capacity, mathematical formulas for computing overall efficiency, and data collection strategies are proposed for rigorous measurement of equipment efficiency and equipment capacity. Measurement of overall equipment effectiveness (OEE) under the TPM paradigm is revised to become a true quantitative measure of efficiency that we term overal...
