A patient with a brain tumor is undergoing a gamma knife treatment (see Section 31.4). Multiple sources of 60Co emit two gamma rayswith a total energy of 2.50 MeV. If the activity of all the sources combined is 5.00 mCi, what is the biologically equivalent dosedelivered to the brain tumor in one hour? The mass of the tumor is 0.150 kg. Since the half-life of 60 Co is 5.27 yr, we can assume theactivity remains constant during the procedure.NumberUnits

Drug Y is a new agent for a rare fatal disease. Drug Y is said to cost more but more effective than Drug X, which is used for the same disease. On the average Drug X can extend life for 5 years at a cost of $10,000 while Drug Y can extend life for 6 years at a cost of $80,000 Previous research has shown that quality of life of people living with the disease is 0.3. Calculate the QALYs associated with each drug.
The following information has been gathered on the costs and effectiveness of the two treatments, A and B. In this problem, costs and consequences are not discounted. Treatment A Treatment B Mortality rate 2% 5% Life expectancy for survivors 20 years 10 years Initial treatment cost $10,000 $3,000 Follow up costs, year 1 $5,000 $1,000 Annual follow up costs, all subsequent years $1,000 $500 What is the ICER?
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 125 grams of a radioactive isotope, how much will be left after 3 half-lives? Round your answer to the nearest gram.
A proximity sensor attached to the tip of an endoscope could reduce risks during eye surgery by alerting surgeons to the location of critical retinal tissue. If a certain eye surgeon expects that by using this technology, he will avoid lawsuits of $0.6 and $1.35 million 2 and 5 years from now, respectively, how much could he afford to spend now if his out-of-pocket costs for the lawsuits would be only 10% of the total amount of each suit? Use an interest rate of 10% per year.
The COVID-19 pandemic has affected more than 20 million people worldwide with a death toll of over 700 thousand. Continuous Positive Airway Pressure (CPAP) therapy is known to reduce the need for mechanical ventilation (MV) in treating hypoxic COVID-19 patients. We present OxyJet CPAP, an electricity-free low-cost noninvasive positive pressure ventilation (NIPPV) system specifically designed for low and middle-income country (LMIC) hospitals. It can provide a 20cm H2O positive end-expiratory pressure (PEEP), peak inspiratory flow-rate up to 65 liters/min (LPM), and a fraction of inspired oxygen (FiO2) of up to 95%. The device utilizes the mechanics of a jet pump driven by high-pressure oxygen to increase the volumetric flow rate by entraining atmospheric air. We use a snorkeling mask (as helmet/hood) to deliver CPAP therapy to reduce aerosolization risk. Although High Flow Nasal Oxygenation (HFNO) is effective in treating severe COVID-19 patients, it is too expensive for public…
Parasite Engineering is developing a new product for the parasitic market that services parasites. The opportunity is estimated to be worth $1.0B measured in today’s dollars. The company will need to spend $500M today to begin the research. In five years, the company will have to make a decision as to whether to go into full scale production and begin selling the drug. At that time, the company estimates it will cost $1.5B to move forward. If the appropriate risk-free rate is 2.5%, how high must the annual volatility be to make the project worth beginning?
A proximity sensor attached to the tip of an endoscope could reduce risks during eye surgery by alerting surgeons to the location of critical retinal tissue. If an eye surgeon expects that by using this technology, he may avoid lawsuits of Php 0.6 million and Php 1.35 million 2 and 5 years from now, respectively, how much could he afford to spend now provided his out-of-pocket costs for the lawsuits would be only 10% of the total amount of each suit?

Local Hospital (LH) has decided that it would like to send nurses to a local supermarket to provide a free health screening for interested supermarket customers. The screening will consist of measuring the individual’s blood pressure and taking a drop of blood, which will be immediately tested for several critical indicators. The director of public relations at the hospital believes that 100 people will take advantage of the screening each day. The plan is to provide the screening every day for one week; thus, a total of 700 screenings are expected. LH expects the supermarket to provide a $1,000 grant to help defray the costs of the program (since it will likely draw more customers to the store). LH anticipates the following expenses: Test Equipment Rental $500 For 1 week Nurses $50/hr Total of 10 hrs/day for 7 days Blood tests $1 Per individual tested Determine the special purpose budget for the program. Show revenues and expenses by line item, and show the expected profit or loss. If…
Star Inc asked you to evaluate their internal control systems. You believed that Star Inc. has serious flaws in their internal control system. You estimated that the impact associated with this problem is $10 million and that the likelihood is currently 9%. Three procedures can be used to deal with this problem. Procedure A would cost $300,000 and reduce the likelihood to 5%; procedure B would cost $400,000 and reduce the likelihood to 3%. If both procedures were implemented, likelihood would be reduced to 1%. a. What is the estimated expected loss associated with ABC Corporation's internal control problem before any new internal control procedures are implemented? b. Determine which procedure should be implemented. Use computation to support your answer. (
Five years ago, when the relevant cost index was 120, a nuclear centrifuge cost $40,000. The centrifuge had a capacity of separating 1500 gallons of ionized solution Today, it is desired to build a centrifuge with a capacity of 4500 gallons per hour, but the cost index is now 300. Assuming a power-sizing exponent to reflect economies of scale, x, of .075, us the power-sizing model to determine the approximate cost (expressed in todays dollars) of the new reactor. per hour.
. A hospital director is considering two alternative investment programs. Both have costs of $5,000 in year 1 only. Project 1 provides benefits of $2,000 in each of the first 4 years only. Project 2 provides benefits of $ 2,000 for years 6 to 10 only. a. Compute the net benefits using a discount rate of 6 percent. b. Knowing that the calculations are dependent on the discount rate, conduct a sensitivity analysis by re - calculating with a discount rate of 12 percent. Based on your calculations, which investment program should the director choose?
Arctic and Antarctic regions are harsh environments in which to take data. A TempXZ 3000 portable temperature recorder can take and store 32,767 measurements at-40 to 150 °C. A research team from the University of Nova Scotia needs 20 of the recorders, and they are trying to decide whether they should buy them now at $649 each or purchase them 2 years from now, which is when they will be deployed. At an interest rate of 8% per year, how much can each recorder cost in 2 years to render their decision indifferent?
