a. Compare the pathway for synthesis and delivery of anterior vs posterior pituitary hormones.

b. Discuss the conduits that deliver these hormones to their targets.

c. Trace the pathways by which hormones will take to reach all bodily tissues (i.e., head, fingers, toes, viscera).

d. Predict possible medical conditions that can arise if the endocrine and cardiovascular systems fail to work with each other to maintain homeostasis. Discuss possible anatomical and physiological changes in the body.

1) A sample of gas in a balloon has an initial temperature of 45C and a volume of 1.28×10³ L . If the temperature changes to 62C , and there is no change of pressure or amount of gas, what is the new volume, V2 of the gas?

V2=?

2) What Celsius temperature T2, is required to change the volume of the gas sample in Part A (T1=45C, V1=1.28×10³ L) to a volume of 2.56×10³ LL ? Assume no change in pressure or the amount of gas in the balloon.

T2=?

PROBLEM 2 A part of a machine is subject to the following fluctuating stress of σmax = 55 kpsi and σmin = 20 kpsi applied for 7 (104 ) cycles. If the load changes to σmax = 48 kpsi and σmin = -30 kpsi, how many cycles should the spring survive, using the Gerber criterion? The material is AISI 1040 CD and has a fully corrected endurance strength of Se = 27 kpsi. Assume that f = 0.9. Use Miner’s method.

Exothermic Vs. Endothermic Reaction

Reaction progress diagrams for single-step endothermic and exothermic reactions.

a. Devise a general statement about the relationship between Ea and the rate of a reaction. 


b. Describe the effect of temperature on the energy of collisions, and explain how this effect changes the rate of a reaction. 


c. State three things that resulted in an increase in the rate of the reaction. For each of the three things, explain at a molecular level what happens to cause the rate of the reaction to increase. 


Imagine that we are studying the colour coat of a population of chamoix in the Alps. There are two morphs, white and dark brown, which we know to be genetically determined.

(a) We observe that the frequency of brown decreased quite substantially between 2010 and 2011. Give 4 different potential explanations for this decrease

(b) Imagine that we observe that the frequency of brown varies erratically over the next 4 years. Give two potential explanations for the changes in the frequency of brown

Inga consumes only Noodles (N) and Salad (S). Her preferences are of the following form: U (N,S)= N^4S^2

a.If her income is $100 and noodles cost $1 while Salad costs $5, what does she consume?

b. The price of noodles changes to $2. Find her new optimal bundle. The income increases to 200. Find the new optimal bundle.Are noodles a normal or inferior good?

A 5 m wide rectangular channel carries a flow of 20 m³/s. The slope of the channel is 0.005 and the Manning’s n is 0.03. The flow encounters a 0.5 m step up that is 0.1 m long. The depths far upstream and downstream are normal.

1. Classify this channel
2. Qualitatively sketch this scenario, label gradually varied flow curves and provide appropriate depths.
3. Draw this scenario on an E-Y cycle graph, and label all depth changes.

Discuss the evolution of the U.S current account deficit and net foreign assets: how much of the evolution of the deficit (as a share of GDP) is due to changes in private savings, public savings (fiscal deficits) and investment rate (all as a share of GDP) and how much has the role of different factors changed over time? - Based on this analysis, are the U.S. current account and external debt sustainable? Does the U.S. differ or not from emerging markets or not and why?

Rising Edge Detector: The rising-edge detector is a circuit that generates a short one-clock-cycle tick when the input signal changes from 0 to 1. It is usually used to indicate the onset of a slow time-varying input signal. Moore machine state diagram for the rising-edge detector is shown in Figure 6. a. Draw the state diagram for the rising edge detector b. Adapt the Code Example 1 to implement the detector in Verilog
