A 3He filled proportional counter is a common
detector used for measuring fission neutrons (average energy of
about 1-2 MeV.) What is the basis of this detector - what is really
being measured?
Ionization chambers, proportional counters and Gieger-Muller
counters are all gas-filled radiation detectors. Sketch a graph of
the signal (pulse of charge collected) as a function of the voltage
applied. Describe what happens to the number of ion pairs collected
as a function of Applied Voltage, (from very low voltage to high
voltage). In particular indicate the regions of this graph which
define the three different detector types.
A Geiger–Muller tube is a type of gas‑filled radiation
detector. It can detect particles like X‑rays, alpha particles, and
beta rays (electrons). This is useful in quantizing the activity of
a radioactive source or determining if an area containing
radioactive material is safe to enter. Assuming that you have 1mol
of gas, if a Geiger counter is filled with 9674 Pa of argon gas at
room temperature (T=23.3 °C), what is the density,
ρ, of the gas in this Geiger...
Practice Exercise 14: One -way Analysis of Variance (ANOVA) Use
the One-way ANOVA function in SPSS to answer the questions based on
the following scenario. Select Descriptives from the Options menu
to obtain the means and standard deviations. (Assume a critical
level of significance of .05). Researchers are interested in
determining if the type of medication influences the number of days
it takes for symptoms to cease. Thirty-six patients are randomly
assigned to receive Brand X, Brand Y, or Brand...
One way to remove harmful “NOx” (NO and
NO2) atmospheric pollutants from flue gas is the
“thermal deNOx” process, in which NH3 is used to reduce
the NO to N2:
__4__ NO (g) + __1__ O2 (g) + ____ NH3 (g)
→ ____ N2 (g) + ____ H2O (g)
The research lab has several gas cylinders available for
studying this reaction, including one cylinder containing a mixture
of 3.0 wt% NO and 15 wt% O2 in an N2 diluent,
and...
Burping (also known as "belching" or "eructation") is one way
the human body expels excess gas in your digestive system. It
occurs when your stomach fills with air, which can be caused by
swallowing food and liquids. Drinking carbonated beverages, such as
soda, is known to increase burping because its bubbles have tiny
amounts of carbon dioxide in them.
As an avid soda drinker and statistics student, you notice you
tend to burp more after drinking root beer than you...
One way to identify use of methamphetamine in a population is to
monitor the waste water. Methamphetamine is excreted from the body
up to 23% unchanged and can cause unintended environmental
exposures. It has been detected in the sewage of all major cities,
even after sewage treatment. Methamphetamine is organic base with a
pKaof 10.0 [12].
a. Many sewage treatment facilities induce pH ranges from pH 5
to pH 10 to encourage degradation. Is methamphetamine charged at
these extremes? Also,...
Oddly, one way to protect use of Intellectual Property for the
inventor of software is to provide free access to the public under
the concept of material.
One way to implement a queue is to use a circular linked list.
In a circular linked list, the last node’s next pointer points at
the first node. Assume the list does not contain a header and that
we can maintain, at most, one iterator corresponding to a node in
the list. For which of the following representations can all basic
queue operations be performed in constant worst time? Justify your
answers. Maintain an iterator that corresponds to the first...
