41. A protein is subjected to cyanogen bromide treatment, which hydrolyzes peptide bonds after methionine side chains. One of these cyanogen bromide fragments is purified and split into two tubes. Trypsin is added to one tube, while chymotrypsin is added to the other tube. The tryptic and chymotryptic fragments were then sequenced. The sequencing results for each fragment are listed below. Tryptic Fragments Chymotryptic Fragments T1: Y-T-K T2: W-I-L-E T3: A-D-R C1: I-L-E C2: A-D-R-Y C3: T-K-W What is the sequence of the original fragment that was produced by the cyanogen bromide treatment? A. ADRYTKWILE B. YTKWILEADR C. ADRWILEYTK D. YTKADRWILE E. ILEYADRWYTK

Question 1 (6 points) a) The macroeconomic system of a country is described by a standard IS-LM model. Denote by "E?" the initial equilibrium. For unknown reasons, the local consumers suddenly decrease their autonomous level of consumption ($c_0$). Denote by "E?" the new equilibrium. Represent on the graph below the old and the new equilibria. Explain carefully the effect of this change in $c_0$ on Output, Consumption, and Investment. b) Suppose the Central Bank reacts to the change in $c_0$ and implements a change in monetary policy designed to exactly counteract any effect on the level of Output. Denote by "E?" this new equilibrium and represent it on the previous graph. Compare the levels of Output, Consumption, and Investment in equilibrium "E?" (i.e. before the change in $c_0$) to those in equilibrium "E?" (i.e. after the reaction of the Central Bank).

Problem.2 (30 pts) Oil($\rho$ = 888 Kg/m$^3$, $k_p$ = 0.145 W/m$^\circ$C, $\nu$ = 901 x 10$^{-6}$ m$^2$/s, $c$ = 1880 J/kg $^\circ$C, Pr = 10440) is to be heated from 10$^\circ$C to 80$^\circ$C as it flows through a D = 30 cm-internal-diameter, 70-m-long tube. Assume fully developed flow with a velocity profile described as $u = 0.4 \left(1 - \frac{r^2}{D^2}\right)$ The tube is equipped with an electric resistance heater, which provides uniform heating throughout the surface of the tube. The outer surface of the heater is well insulated, so that in steady operation all the heat generated in the heater is transferred to the water in the tube. 1. Determine the mean velocity $u_m$ and and the volume flow rate V. 2. Determine the power rating of the resistance heater 3. Determine the pressure drop and the pumping power requirement to overcome this pressure drop

Question 4: Econometrics Consider the following bivariate regression model: yi = a + Bxi + ui for i = 1..n. The regressor is stochastic and exhibits variability in the sample, i.e. xi = -0. The error term ui is i.i.d. with mean zero and constant variance of Ïƒ^2 for any value of i. Given a random sample of observations {(yi, xi)} from the population of interest, consider the following estimator: Li = 1/xi (a) (3 marks) Under which assumption is Li an unbiased estimator of B? (b) (5 marks) Let us assume that the assumption in (a) is satisfied so that Li is unbiased. Will this assumption also ensure that Li is consistent? In your answer, discuss the difference between unbiasedness and consistency.
