Open symbols indicate exposed tracers and closed symbols indicate buried
tracers. Competent flow duration was estimated using published information
about flow duration exceedence frequency in Allt Dubhaig and an individual
hydrograph analysis in Carnation Creek. Published values taken from Hassan (
1990), Haschenburger (2011), and Lenzi (2004), plus original observations for

The top soil of this area measuring 7 m x 7 m was removed to expose the surface
of the chalk. At the centre of this area, a borehole (cased to 20 m) was drilled to
24 m below ground level and a sampling pump installed with an intake at 23 m
below ground level. 0.5 i 1.0 2.0 3.0 4.0 5.0 Effluent volume (ml) 200 « 100' 12

The most commonly applied nuclides for erosion rate measurements are 3He,
10Be, 26Al and 36Cl. Until recently, use of these nuclides was restricted to
determining denudation rates of exposed bedrock outcrops; recently, several
research groups have begun to measure nuclide abundances in sediments with
the goal of estimating basin-scale rates of denudation. 19.2.1 Cosmogenic
nuclides in exposed outcrops The abundance of a cosmogenic nuclide in a
sample of outcropping ...

This required two separate tracers that both labeled all of the neurons to which
they were exposed, that could be applied to different tributary nerves and
transported through different pathways to the same parent neuron, and that could
then be co-localized in that neuron (Figure 6-3). The process of simultaneous
double-labeling from distal tributaries A and B of a repaired nerve asks three
questions: (1) Which neurons project their axons only down branch A? (2) What
other neurons ...

Tracers were most often belted at every fifth round, seeing one tracer meant you
had not seen four other rounds fired at you. Typical scheme was to fire nothing
until the FAC was flying AWAY from given gun position, then fire one clip before
the aircraft could be turned and thus the firing position was not exposed by the
tracers coming from it. Usually the first indication of the event was a stream of
tracers going past the FAC aircraft from the rear forward. Troll (Trolling) The
dubious FAC ...

Green labeled particles that were deployed at 15 m were in accordance to the
thermocline fluctuation alternately exposed to epilimnetic and hypolimnetic
mixing processes directed either offshore or towards the shore and therefore
dispersed in a much wider radius as can be seen by their recovery at station 10S.
The red and yellow tracers were exposed solely to eplimnetic mixing and
therefore affected strongly by resuspension processes. The dispersion of shallow
sediments ...

The old maximum permissible concentrations (MPC) are to be replaced with a
new set of numbers given in appendix B of the proposed regulations as Table 1
for occupationally exposed workers, Table 2 for unrestricted areas, and Table 3
for disposal into the sewer. The values for occupational exposure to some
common waterflood tracers were abstracted from Table 1 above and appear in
Table 2.4 in this chapter. For the first time, these regulations also go into detail on
how the ...

Next, the sorbent is carefully extracted to quantify the mass of all contaminants
intercepted by the flux meter and the residual masses of all resident tracers. The
contaminants' masses are used to calculate time-averaged contaminant mass
fluxes, while residual resident tracer masses are used to calculate cumulative
fluid flux. Depth variations of both water and contaminant fluxes can be measured
in an aquifer from a single flux meter by vertically segmenting the exposed
sorbent ...
