Scientists apply their knowledge of evolution to improve vaccines. Instead of delivering a dead virus or its some vaccines induce an immune response by delivering a live virus. Scientists must first weaken the virus using the process of so that no serious illness results. To produce a live polio vaccine, for instance, researchers force the virus to evolve in the cells of a species in which it does not naturally replicate. The virus manages to survive, mutating as it slowly replicates. As the virus adapts to these cells, it becomes increasingly able to infect human cells. However, injected in the human body, it can still elicit a strong immune response. Scientists are also using their knowledge of evolution to create vaccine. Instead of formulating a new vaccine every season, scientists are trying to develop one that stimulates the production of that would target all strains of the virus. Standard vaccine antibodies bind to the tip of the stalk, which continually mutates. However, the new antibodies would bind to the which is nearly identical across all strains and not likely to mutate without causing harm to the virus.

The budgeted unit sales are 12,500 units, 37,000 units, 15,000 units, and 29,000 units for quarters 1-4, respectively. Notice the company experiences peak sales in the second and fourth quarters. The budgeted selling price for the year is $29.00 per unit. The budgeted unit sales for the first quarter of the following year is 13,000 units. All sales are on credit. Uncollectible accounts are negligible and can be ignored. Seventy-five percent of all credit sales are collected in the quarter of the sale and 25% are collected in the subsequent quarter. Each quarter's ending finished goods inventory should equal 15% of the next quarter's unit sales. Each unit of finished goods requires 2.5 yards of raw material that costs $3.00 per yard. Each quarter's ending raw materials inventory should equal 10% of the next quarter's production needs. The estimated ending raw materials inventory on December 31 of next year is 5,000 yards. Seventy percent of each quarter's purchases are paid for in the quarter of purchase. The remaining 30% of each quarter's purchases are paid in the following quarter. Direct laborers are paid $18 an hour and each unit of finished goods requires 0.25 direct labor-hour to complete. All direct labor costs are paid in the quarter incurred. The budgeted variable manufacturing overhead per direct labor-hour is $3.00. The quarterly fixed manufacturing overhead is $145,000 including $20,000 of depreciation on equipment. The number of direct labor-hours is used as the allocation base for the budgeted plantwide overhead rate. All overhead costs (excluding depreciation) are paid in the quarter incurred. The budgeted variable selling and administrative expense is $2.00 per unit sold. The fixed selling and administrative expenses per quarter include advertising ($25,000), executive salaries ($64,000), insurance ($12,000), property tax ($8,000), and depreciation expense ($8,000). All selling and administrative expenses (excluding depreciation) are paid in the quarter incurred. The company plans to maintain a minimum cash balance at the end of each quarter of $30,000. Assume any borrowings take place on the first day of the quarter. To the extent possible, the company will repay principal and interest on any borrowings on the last day of the fourth quarter. The company's lender imposes a simple interest rate of 3% per quarter on any borrowings. Dividends of $15,000 will be declared and paid in each quarter. The company uses a last-in, first-out (LIFO) inventory flow assumption. This means the most recently purchased raw materials are the "first-out" to production and the most recently completed finished goods are the "first-out" to customers. 1.The budgeted unit sales are 12,500 units,37,000 units,15,000 units,and 29.000 units for quarters 1-4,respectively.Notice the company experiences peak sales in the second and fourth quarters.The budgeted selling price for the year is $29.00 per unit.The budgeted unit sales for the first quarter of the following year is 13,000 units 2.All sales are on credit.

Example 9.18 As we have seen in exercise 9.2, the function $y_1(x) = 1/x$ solves the equation $x^2y'' + \frac{3}{2}xy' - \frac{1}{2}y = 0$. We divide by $x^2$ to bring the equation into the form required for Abel's theorem. Then $p(x) = 3/(2x)$. Hence, the Wronskian of two solutions, $y_1$ and $y_2$ satisfies $W'(x) = -\frac{3}{2x}W(x)$. This is a linear first-order equation that we can solve to find $W(x) = \frac{c}{x^{3/2}}$ for some constant $c$. We can choose $c$, so we choose $c = 1$. Now we expand $W$ in terms of $y_1$ and $y_2$ and substitute the expression that we have for $y_1$. We find $W = y_1y_2' - y_1'y_2 = \frac{1}{x}y_2' + \frac{1}{x^2}y_2 = \frac{1}{x^{3/2}}$. This is now a first-order equation for $y_2$, which we can solve by integrating factors. We obtain $y_2(x) = \tilde{c}\sqrt{x}$ for some constant $\tilde{c}$.
