A population of 1200 was recruited for a 5-year study of heart disease. Upon initial exam prior to the start of follow-up, 200 cases of heart disease were diagnosed and excluded from further study. Over the 5-year study period, 320 cases of heart disease developed, and 70 of those incident cases died from the disease. The study participants contributed a total of 3,800 person-years of follow-up time. ______________________________________________________ Calculate the cumulative incidence of heart disease over the 5-year study period. Express as a percentage, and round to the nearest whole number. Include only the numerical answer (no units) in the answer box.

4. What is the oligomeric state of E. coli beta-glucuronidase? What is the overall size of the protein? What kind of secondary structures do you see in the protein? You may need to use protein visualization software like ICM-Pro (what we used in CHEM 471 to look at protein structures) or go to the rcsb.org website and look at the structure that is described in the article given to you (PDB ID: 3LPF – don’t forget to use the BioMolecule Generator, if using ICM-Pro).

Q2. A cellphone signal at 900 MHz propagates in the grey matter of the brain which has constitutive parameters $\epsilon_r$ = 50, $\sigma$ = 0.8 S/m, and $\mu_r$ = 1. (i) Determine the loss tangent tan $\delta$, the loss angle $\delta$, the propagation constant $\gamma$, the attenuation constant $\alpha$, the phase constant $\beta$, the skin depth $\delta$, the wavelength $\lambda$ and the phase velocity $u_p$. (ii) Find the distance inside the brain at which the magnitude of the fields is 10% of that at the surface. State any assumption made. Ans: tan $\delta$ = 0.32, $\delta$ = 17.74$^\circ$, $\gamma$ = 21.34 Np/m + j134.95 rad/m, $\alpha$ = 21.34 Np/m, $\beta$ = 134.95 rad/m, $\delta$ = 0.0469 m, $\lambda$ = 0.0466 m, $u_p$ = 4.19 × 10$^7$ m/s, 0.108 m

Sec6.6: Problem 16 (1 point) Book Problems 43 Enter T if the given statement is true or F if it false. Only three attempts are allowed on this problem. 1. $\int_1^{\infty} \frac{dx}{x - e^{-9x}}$ is divergent because $\frac{1}{x - e^{-9x}} \ge \frac{1}{x}$ and $\int_1^{\infty} \frac{dx}{x}$ is divergent 2. $\int_1^{\infty} \frac{dx}{x + e^{9x}}$ is convergent because $\frac{1}{x + e^{9x}} \le \frac{1}{x}$ and $\int_1^{\infty} \frac{dx}{x}$ is convergent 3. $\int_1^{\infty} \frac{dx}{x + e^{9x}}$ is divergent because $\frac{1}{x + e^{9x}} \le \frac{1}{x}$ and $\int_1^{\infty} \frac{dx}{x}$ is divergent 4. $\int_1^{\infty} \frac{dx}{x + e^{9x}}$ is convergent because $\frac{1}{x + e^{9x}} \le \frac{1}{e^{9x}}$ and $\int_1^{\infty} \frac{dx}{e^{9x}}$ is convergent
