Trace abstraction is typically required to compute statistics of complex system metrics that are not directly computable from the low-level trace events [34].
One method for low-level (trace) N-terminal labeling is based on the use of an Escherichia coli initiator tRNAfMet misaminoacylated with methionine modified at the α-amino group.
These low-level traces are used to create a machine code coverage report.
However, Zielinski et al. (2011) showed that Jordanian PG contained low levels in trace elements.
Moreover, the use of straw for biogas production is restricted by its high C/N ratio and low levels of trace elements, limiting microbial growth and activity.
In many areas now, we're measuring parts per billion, which is very, very low levels of trace gas in exhaust".
Silicon carbide is cheaper than a combination of ferrosilicon and carbon, produces cleaner steel and less emissions due to low levels of trace elements, has a low gas content, and does not lower the temperature of steel.
Evidence suggests that even low levels of trace metal exposure, such as cadmium and lead, are linked to numerous negative health outcomes, including cognitive deficits and other delayed developmental milestones [ 34, 35, 37].
Research investigating the properties of uncombusted coal, collected from coal mines and from homes of Xuanwei and Fuyuan residents has shown that smoky coal contains high amounts of volatile organic compounds (i.e., hydrocarbon content) and quartz but generally low levels of trace elements when compared to smokeless coal.
The inconsistent observation of low levels or traces of infection in certain non-neural and non-lymphoreticular tissues is in general a feature of both natural and experimental TSE.
Members of the public are to be asked if they find low levels - or "trace contamination" - of horse and other species in beef products acceptable.
