From quartz hazard to quartz risk: the coal mines revisited.
Following the classification of quartz as a human carcinogen by the IARC, many standard-setting committees are currently trying to convert this hazard into their national or EU standards. Since human data to set a safe exposure limit for quartz are limited, we hypothesized that lung burden data on quartz in coal miners' lungs after lifetime exposure could be used to set a non-carcinogenic lung ...
متن کاملQuartz-enhanced photoacoustic spectroscopy.
A new approach to detecting a weak photoacoustic signal in a gas medium is described. Instead of a gas-filled resonant acoustic cavity, the sound energy is accumulated in a high- Q crystal element. Feasibility experiments utilizing a quartz-watch tuning fork demonstrate a sensitivity of 1.2x10(-7) cm(-1) W/ radicalHz . Potential further developments and applications of this technique are discus...

متن کاملResolving Quartz Overloading
Quartz is a new declarative hardware description language with polymorphism, overloading, higher-order combinators and a relational approach to data flow, supporting formal reasoning for design verification in the same style as the Ruby language. The combination of parametric polymorphism and overloading within the language involves the implementation of a system of constrained types. This pape...
متن کاملQuartz Crystal Based Microgravimetric Immunobiosensors
Piezoelectric crystal immunosensors have attracted considerable interest in the last few years since the monitoring of a specific substance is central in many applications. These sensors work on the principle of measuring a small change in resonant frequency of an oscillating piezoelectric crystal due to change in mass on the sensor surface. Because of their low cost and high Q-factors, these m...
