Aiman is trying to isolate intracellularprotein of a recombinant microorganismgrowing in hisresearch laboratory. Theprotein is said to be used in medicalsector and cannot withstand temperaturefor more than 40\deg C and has a size of100kD. As a chemical engineer friend toKamal,could you advise him on:a) His firstoption is to recover the intracellularprotein using osmotic pressure. Thepressure dropbetween with outside andinside concentrations are 0.01M and 0.2Mrespectively, what is thepressure dropvalue of if the salts are disassociatecompletely.(5 marks) b) What can be saidof this pressure drop value and why?(5marks)c) His second option is to use apressure valve homogenizer. What is thecell breakage at 0.9? Assuming the value1.77 forof k = 5.91 x 10* MPa and athe range pressure of50MPa. Please showall work.

a) To help Aiman isolate the intracellular protein using osmotic pressure, we need to calculate the…

You are the laboratory manager. The hospital administration wants to penetrate the market and expand the business by performing Parathyroid Surgeries (reimbursement $15,000). They have enticed a prominent surgeon to join the staff He plans on scheduling four surgeries per week - two on Tuesday and two on Thursdays. Every case will need on intact Parathyroid Hormone (PTH) performed STAT during surgery. You currently send this test to your reference laboratory with a minimum 24-hour TAT. None of the analyzers currently in your lab are capable of running this test. The best pricing you obtain is from Siemens Diagnostics for an Immulite 1000. The price of the analyzer is $75,000. The price of the test kit is $800 for 100 tests. The test requires three levels of controls run per 24 hours. The stability of the test kit once opened is eight weeks. Reimbursement for the test is $20. You realize that you will only be able to run on average 32 tests (patient reportable results) before discarding…
You are a manager at Northern Fibre, which is considering expanding its operations in synthetic fibre manufacturing. Your boss comes into your office, drops a consultant's report on your desk, and complains, "We owe these consultants $1.6 million for this report, and I am not sure their analysis makes sense. Before we spend the $29 million on new equipment needed for this project, look it over and give me your opinion." You open the report and find the following estimates (in millions of dollars): Sales revenue - Cost of goods sold = Gross profit - General, sales, and administrative expenses - Depreciation = Net operating income Income tax = Net income 1 2 34.000 34.000 20.400 20.400 13.600 13.600 2.320 2.320 2.900 2.900 8.380 8.380 2.933 2.933 5.447 5.447 9 34.000 20.400 13.600 2.320 2.900 8.380 2.933 5.447 10 34.000 20.400 13.600 2.320 2.900 8.380 2.933 5.447
Your firm has acquired a bag of 29 pills of the cognitive-enhancing, nootropic drug called NZT-48. This has opened up four new potential projects for your firm that would not be possible with only your regular unenhanced employees’ feeble meatbag brains. Each project is non-repeatable and of equal time. You have calculated the NPV of each project as well as the requested number of NZT-48 pills by each project’s exploratory team: Project Codename NPV Pills Requested Commodus $42,800 14 Caligula $70,500 20 Nero $24,150 5 Elagabalus $72,200 19 Assume that you can do partial projects whereby you can allocate less pills than the number requested by the team. This would give you a pro-rata portion of that project’s NPV (i.e. the amount of pills you allocate as a proportion of the number requested). The maximum total NPV your firm can achieve through allocating its 29 NZT-48 pills across these four projects is $$.(Round up to the nearest dollar)

Now that operations for outdoor clinics and TEAM events are running smoothly, Suzie thinks of another area for business expansion. She notices that a few clinic participants wear multiuse (MU) watches. Beyond the normal timekeeping features of most watches, MU watches are able to report temperature, altitude, and barometric pressure. MU watches are waterproof, so moisture from kayaking, rain, fishing, or even diving up to 100 feet won’t damage them. Suzie decides to have MU watches available for sale at the start of each clinic. The following transactions relate to purchases and sales of watches during the second half of 2025. All watches are sold for $491 each. July 17 Purchased 41 watches for $5,781 ($141 per watch) on account. July 31 Sold 31 watches for $15,221 cash. August 12 Purchased 31 watches for $4,681 ($151 per watch) cash. August 22 Sold 21 watches for $10,311 on account. September 19 Paid for watches purchased on July 17. September 27 Receive cash of $20,400…
An IE works in the automation department of a surgical equipment manufacturing company that produces specially ordered equipment for hospitals. To upgrade the quality of the assembly process of the camera used in laparoscopic surgery probes, two approaches are available: make and buy. The make alternative has an initial equipment cost of $175,000, a life of 5 years, a $25,000 salvage value, a processing cost of $3,000 per camera, and an M&O cost of $65,000. The buy alternative requires contracting the assembly operation externally at a cost of $6,000 per camera. If the MARR is 12% per year, how many cameras per year must be assembled to justify the make alternative? cameras must be assembled per year to justify the make alternative.
Polaris Industries wishes to purchase a multiple-use in-plan ”road test” simulator that can be used for ATVs, motorcycles, and snowmobiles. It takes digital data from relatively short drives on a desired surface - from smooth to exceptionally harsh - and simulates the ride over and over while the vehicle is mounted to a test stand under load. It can run continuously if desired and provides opportunities to redesign in areas of poor reliability. It costs $128,000 and its market value decreases 30% each year. Operating costs are modest; however, maintenance costs can be significant due to the rugged use. O&M in the first year is expected to be 10,000, increasing 25% each subsequent year. MARR is 15%. What is the optimum replacement interval? Show screen shots of any formulas used in Excel.
CyberBest started to develop an anti-malware application on August 1, 20X1. It reached technological feasibility on March 1, 20X2, and the application was released on April 30, 20X2.

August 1 through December 31, 20X1 $5,000,000 January 1 through February 28, 20X2 1,600,000 March 1 through April 30, 20X2 1,800,000 Determine the amount of asset and the amount of R&D expenses relating to the development of this anti-malware application. $1,800,000 asset, and $6,600,000 R&D expenses $5,000,000 asset, and $3,400,000 R&D expenses $6,600,000 asset, and $1,800,000 R&D expenses $3,400,000 asset, and $5,000,000 R&D expenses
Three types of bits can be used in an automated drilling operation. A bright high-speed steel (HSS) bit is the least expensive to buy, but it has a shorter life than either gold oxide or titanium nitride bits. The HSS bits will cost $3500 to buy and will last for 3 months under the conditions of use. The operating cost for these bits will be $2000 per month. The gold oxide bits will cost $6500 to buy and will last for 6 months with an operating cost of $1500 per month. The titanium nitride bits will cost $7000 to buy and will last 6 months with an operating cost of $1200 per month. At an interest rate of 12% per year compounded monthly, which type of drill bit should be selected? Use a future worth analysis.
