For a bronze alloy, the stress at which plastic deformation
begins is 300 MPa and the modulus of elasticity is 115 GPa.
What is the maximum load (in kN) that may be applied to a specimen
having a cross-sectional area of 70 mm2 without plastic
deformation?
And if the original specimen length is 100 mm, what is the
maximum length (in mm) to which it may be stretched without causing
plastic deformation?
Name and detail the mechanism(s) through which this DNA damage
can occur. What mechanism(s) have cells developed to deal with this
damage when it is encountered? Detail how this led to the
elucidation of DNA repair enzymes in your answer.
What is the Law of One Price?
Describe the mechanism through which the Law of One
Price leads to the Theory of Purchasing Power Parity. What is the
Theory of Purchasing Power Parity?
a) Describe in less than 300 words ONE type of apparatus (using
a diagram if it helps) that is used to collect diffraction
information using X-rays. Include in your answer why this set up is
used to successfully get diffraction from crystals?
b) Describe in less than 300 words how the equilibrium
one-dimensional band diagram of a pn junction (under zero bias)
evolves based on diffusion and drift currents that occur due to the
differing impurities in the p and...
You may choose more than one answer. Which of the following is a
mechanism of signal amplification in the cAMP-PKA pathway?
One signal molecule, epinephrine, activates lots of
G-proteins.
When activated, adenylyl cyclase synthesizes many cAMP
molecules.
cAMP-activated protein kinase A (PKA) can activate a number of
target proteins by phosphorylation.
Proteins phosphorylated by PKA can further activate other
proteins that make other products
