Chapter 18, Problem 23RQ
One of the 14 NAE Grand Challenges is Engineering Better Medicines. Part of this Grand Challenge is creating individual medication plans for each patient, rather than sweeping recommendations based upon research using only one subset of the population. For example, in the past most heart attack protocols were created for white mates. It has been discovered in recent years that women have different initial symptoms and respond better to a different treatment protocol than their male counterparts.
To bettor tailor the medicine to the individual, you wish to write a computer program to allow the user to enter several variables. The program will then produce a suggested solution. Write the MATLAB code to:
a. Ask the user to enter his or her name (text).
b. Ask the user to type his or her weight (a number) in pounds-force.
c. Ask the user to select his or her symptom from a menu, given the following choices.
■ Cold
■ Flu
■ Migraine
d. Based upon the answer selected to the menu, set the medicine name, volume [mL] and mass [g] of the medicine tablet
e. Write (a) the function call from the program and (b) a function that will accept the mass and volume of the desired medicine from the main program and return the specific gravity of the desired medicine tablet to the program. Remember: The density of water is 1000 kilograms per cubic meter,
f. Write (a) the function call from the program and (b) a function that will accept the weight of the person, specific gravity of the medicine, and tablet volume from the main program and return the number of tablets recommended for the person to the program. To determine the number of tablets needed, the following equation should be used and then rounded up to the next whole number of tablets. Any calculations or conversions necessary should appear in the function.
g. Write an output statement that appears as follows, where N is replaced by the name of the medicine and x.xxx is replaced by the calculated specific gravity formatted to show three decimal places: The specific gravity of N is X.XXX.
h. Write an output statement that appears as follows, where AAAA is the name of the user, n is the name of the medicine, yyy is the name of their symptom, and Z is the number of tablets recommended
AAAA, your recommended dosage of N to treat a YYY: Z tablets.
Note
Although you may use conditional statements to solve this problem, none are needed if you set up the medicine data table as a cell array.

Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed.
Background information of Ethanol:
Boiling Point = 78 0C
Melting Point = -114 0C
Starting Temperature = -120 0C
After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely.
After eight more minutes, it begins to boil. It boils for six minutes.
Heat is added for two more minutes until ethanol reaches 80 0C.
Label “melting” where this takes place.
Label “vaporization” where this takes place.
Label “phase change” where a phase change occurs.
Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS.
Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.
Cathy Gwynn for a class project is analyzing a "Quick Shop" grocery store. The store emphasizes quick service, a limited assortment of grocery items, and higher prices. Cathy wants to see if the store hours (currently 0600 to 0100) can be changed to make the store more profitable.

- Read the summary below and answer the questions that follow: The Orange Girl – all the juice and nutrition you can ask for Growing up on a citrus farm in Mpumalanga, Yoliswa always wanted to escape to the city. In her little mind, she saw the farm life as the hardest endurance test any individual can be subjected to. She qualified with a mechanical engineering degree and started working in food manufacturing facilities in the city of Jo’burg. The conventional rat race in the city wore Yoliswa down a lot, she started escaping to the farm whenever she got a chance. One day, five years ago, on one of these visits, she found herself wandering on the farm, carried away in childhood memories of how she used to eat oranges directly from trees when they were in season. The farm owner had allowed Yoliswa’s parents to use a section of the farm to grow their own oranges for themselves.

- Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N.
