A Charpy specimen made of iron with dimensions of 10 mm x 10 mm
x 55 mm is irradiated in a thermal reactor with a flux of
1012neutrons cm-2s-1for 30 days. The resultant activity is due to
neutron absorption in the 0.31% 58Fe present in the specimen. Iron
has an effective atomic mass of 55.85 and a density of 7.87
g/cm3.
Determine:a) the activity (Bq) of the Charpy specimen upon
removal from the reactor;

reaction 24 hours a day for 365 days (continuous operation
for a year)? The average molecular weight of the FAMEs is 292.2
g/mol, MW of vegetable oil: 883 g/mol and density: 0.875 g/mL.
Assume that vegetable oil is the limiting reagent. Consider how

Research suggests that it takes about 3,000 raw, unwritten ideas
to produce a single, commercially-successful new product. To learn
marketing lessons and convert potential failures to successes, we
can analyze why new products fail and then study several failures
in detail.
Both marketing and nonmarketing factors contribute to
new-product failures. Using the research results from several
studies on new-product success and failure, we can identify
critical marketing factors—which sometimes overlap—that often
separate new-product winners and losers:
1. Insignificant point of...

A school psychologist is interested in whether time has changed
the problem with student parking that has been discussed for a few
years. As the student population has grown the psychologist fully
suspects that the time to find parking has become worse rather than
better for the student body. Over the past decade the average
amount of time to find parking for students is 15 minutes (µ=15).
The current sample’s information is as follows: M=19 minutes and a
