With the spread of the Coronavirus, much of the business community’s traditional way of looking business has changed.  The business community is looking more flexible business operations with minimum human interaction with least amount of stocks goods and services.  Perhaps e-business, efficient customer care and response, electronic billing and payment systems and the Japanese concept of just-in-time delivery are considered to be the components of a viable business operation.  

In your BUS 209 class, you learnt Solving Problems, Some Special Equations and Rates of Change, Summarizing Data, Measuring Uncertainty and Probability Distributions.  Examine the different components of viable business operation by applying quantitative methods to collect and describe data using sampling methods. To assess the components risk and uncertainty, you may use probability distributions, expected value, variance and standard deviation.  

Hint: The following functions are considered to be the most important business functions

1. Management Information Function;

2. Innovation (Research & Development)

Only one answer is correct for each question

Q1:

Lactobacillus acidophilus is responsible for

Find an important engineering failure that involves some of the topics discussed in MSE 350. Describe the failure, why it occurred, the damage (human, environmental, and economic) and the changes that could have been made in the design to avoid the failure. Was the failure caused by lack of engineering knowledge at the time, engineering error, or management/government error? Discuss!!

For each of the following common items, identify what they are commonly made of, the material type (composite, metal, semiconductor, polymer , ceramic, glass. Describe why that material type is used. Include at least two references for your answers (websites are fine, but try and find good ones). If more than one material type is used in the items, include them all! Be careful to use proper engineering vocabulary when answering this question!

Abrasives for grinding metal

Automobiles Integrated circuits

Airplanes Bridges

Solar panels

Latex paint

Soda bottles

Polyvinylchloride (PVC) plumbing pipe

The following stem and leaf diagram show the number of days in a year a team of thirty technicians were absent from their work on medical grounds. Stem and Leaf Diagram of Number of Days Absent from Work Stem (tens) Leaf (ones) 01 1 23 2 017 3 1358 4 23678889 5 01345778 6 0123 a. Calculate the median number of days of absenteeism in the company. b. Calculate the interquartile range of the number of days of absenteeism in the company. c. You are presenting the dispersion of absenteeism rates to your manager who is not trained in statistics. Would you consider using quartiles to present dispersion information or the variance? Explain. d. The human resources manager of the company mentions that the company has always used median to present the absenteeism level of its workers. Based on the stem and leaf diagram, is his choice of measure of central tendency/location justified? Explain.

I am doing a presentation on Phosphorus and am addressing the following (below) and would appreciate information for all of the headings THANK YOU

For assignment 3 you will exhaust your understanding of an assigned biogeochemical element by addressing and TEACHING the following topics in your presentation:

1. Introduction

2. The global cycle/ elemental forms

3. Temporal variation

4. The soil cycle/ elemental forms

5. Role of element in soil and how it is affected by the physical, chemical, and biological environment You may consider answering the following questions within your presentation:

6. What are the global scale pools and fluxes?

7. What are the stable and labile forms of your element and what are the processes involved in creating these elemental forms?

8. How does the cycling of your element influence ecosystem structure and function?

9. What are the environmental implications if the elemental cycle is disturbed?

10. Are there concerns regarding ecosystem health, soil health, human health?

I want you to research how to purify a protein from cell culture. After purification of the protein, you would need to quantify the protein using Bradford Assay and run the protein on SDS-PAGE gel for Western blot analysis to determine the amount of specific in a sample.

1. Write out a protocol for the isolation of protein from human cell culture- you can determine the type of cells you are purifying the protein from
2. Write out a protocol for the Bradford assay including the standard curve and explain how you would determine the amount of protein in your sample from the standard curve.
3. Write out the protocol for the Western Blot analysis making certain to fulling explain:
   1. How an SDS-PAGE gel separates proteins
   2. How proteins are transferred from a SDS PAGE gel to the nitrocellulose filter
   3. Different solutions and their uses
   4. Different antibodies and their uses
   5. How you can visualize the signal and thus your protein

If a firm adjusted their prices to be high enough to cover their Average Total Costs and if they were not concerned with MC=MR, then we could probably assume they are a nonprofit entity.        

True or False

Who will really end up paying for higher taxes on corporate profits if we assume the product that they sell is very inelastic?

Multiple Choice

• The stockholders of the firm will pay this tax when they file their individual tax returns.

• The retail consumer will pay these taxes through higher prices.

• The state government pays these taxes to the federal government

• 1. The senior executives actually pay these taxes when they file their individual tax returns.    

29

If we took an elastic demand curve and raised the price, then this would be the best pricing strategy to maximize total revenue.

True or False

The formula that describes human behavior is which of the following:

Multiple Choice

• MB = MC

• E > 1

• E = 1

• MC = MR

TRUE or FALSE

1. Objective of engineering risk management is early and continuous identification, management, and resolution of risks such that engineering a system is accomplished within cost, delivered on time, and meets performance requirements.

2. A risk is an event that, if it occurs, adversely affects the ability of an engineering system project to achieve its outcome objectives.

3. An event is uncertain if there is indefiniteness about its outcome.

4. Epistemic uncertainty refers to uncertainty about an event due to incomplete knowledge.

5. A system’s elements may include people, cultures, organizations, policies, services, techniques, technologies, information/data, facilities, products, procedures, processes, and other human-made (or natural) entities.

6. General systems theory is a philosophy that considers how to view and pursue scientific inquiry.

7. Daniel Bernoulli formed the idea that valuing monetary loss or gain from a gamble or lottery should be measured in the context of a player’s personal circumstance and existing wealth.

8. Risk management always involves “cost-benefit-risk” tradeoff and analyses.

Malaria is a mosquito-borne disease caused by parasites of the obligate intracellular Apicomplexa family, the most deadly of which, Plasmodium falciparum, prevails in Africa. Malaria imposes a huge health burden on the world’s most vulnerable populations, claiming the lives of nearly a million children and pregnant women each year in Africa alone. Although there is keen interest in eradicating malaria, we do not yet have the necessary tools to meet this challenge, including an effective malaria vaccine and adequate vector control strategies. Here we review what is known about the mechanisms at play in immune resistance to malaria in both the human and mosquito hosts at each step in the parasite’s complex life cycle with a view towards developing the tools that will contribute to the prevention of disease and death and ultimately the goal of malaria eradication. In so doing we hope to inspire immunologists to participate in defeating this devastating disease.
