## C Programming Assignment:

Question:

Degrees are a measurement of an angle such that a full rotation of a circle is 360 degrees. Whereas a radian is defined as the angle of an arc with a length equal to the radius of a circle, a full rotation in radians is 2ππ. This is represented on the circle below:

You are to create a program that allows the user to either create a table of degrees to radians, or
radians to degrees. The format and steps are described in ‘Program’.

Solve the problem individually by implementing a program using C code.

## Nursing Report Writing:

Conduct an analysis of the Case: Findings of the Inquest into the death of Shona Hookey addressing the three sections as outlined.

In the report of the Inquest into the death Shona Hookey the Coroner identified the cause of death as peritonitis due to an ischaemic bowel. There were many questions and circumstances surrounding the death of Shona. These questions have been raised throughout the Coroners Case presented. This assignment requires students to focus on the nursing care provided to Shona in relation to patient safety, law and ethics.

Shona Hookey suffered from a severe intellectual disability and had a medical history that included epilepsy, stroke and right sided hemiplegia. She also had a history of consuming foreign objects. Her disability and medical conditions required Shona to reside in a group home managed by NSW Trustee and Guardian. Shona was of Aboriginal descent. Her family loved and missed her and her death on July 19, 2013 deeply affected her carers and her family.

A number of carers, ambulance staff, registered nurses and doctors were involved in Shona’s care on the 18 and 19th July, 2013. The role of the carer, the ambulance officers and the registered nurse were key within the chain of events that transpired and within particular areas that foreshadowed the subsequent chain of events in the deterioration of Shona.

Assignment Section One: Patient Safety

Conduct an analysis of the nursing care (pages 11 – 24) that is outlined by the coroner in the Inquest into the death of Miss Shona Hookey in terms of the involvement of the Registered Nurses in the Emergency Department and their overarching communication and accountability in clinical decision making, care delegation and care provision.

a. Use relevant literature to assist your critique – MINIMUM of three for passing mark – more are expected.
b. It is expected that you will substantiate your points with literature regarding best practice or literature related to Patient Safety and care at times of acute illness and patient deterioration.
c. Note: the literature needs to be greater than practice includes more than psychomotor skills, it is also knowledge, communication, monitoring, reporting, accountability, delegation and responsibility). Do not provide just a synopsis of the case in itself.
d. Approx. 1100 words for this section

Assignment Section Two: The Tort of Negligence

Explain how the tort of negligence would be applied to the registered nurse/clinical nurse involved in this case.

Outline the elements which would need to be proved in order to advance a successful claim for negligence.

In the event that the Coroner decided to refer the Doctors and Registered Nurses involved in the case to the regulating authority AHPRA. What clinical situation may give rise to this situation?

There is also the potential that a civil case could be made against the parties involved. Conditions of negligence would need to be met for a court case to be successful. Using the registered or clinical nurses as an example, outline the elements that would need to be demonstrated in order to substantiate a claim of negligence.

f. Approx. 500 words

Assignment Section Three: Ethical Issues

A number of ethical issues arose in the case that could be discussed in relation to the care provided and the testimonies discussed (30 – 36).

Critique the actions of the Care Workers for Disability Services and the Registered Nurses in the Emergency Department (approx. 2-4 issues) using principles of ethics and considering the care requirements of Shona whilst in
care.

g. Utilise published academic texts and current literature to assist your critique.
h. Approx. 400 words

In the process, students should provide an executive summary, background to the company and the problem they face, a discussion of the marketing problem and research problem, at least 2 research objectives, and least 5 research questions across the research objectives.

## Report Writing Assignment:

Questions:

A hydro scheme has a catchment area of 120 km2, a capacity of 10 billion litres and a head of 200 m. The turbine maximum electrical output is 100 MW and it is 90% efficient. The rainfall data for 2015 (in mm per month) is shown below including an estimate of the percentage of the rainfall that reaches the reservoir.

1.1 Import the data into Microsoft Excel and construct a model that will allow you to determine if it is possible to produce a total of 100 MW of electrical power for a minimum of 2 hours of the day over the entire year;  if not, state the minimum value.

1.2 Show how the problem can be solved in a more flexible way using dedicated modelling software such as Matlab;

OR

Present the strategy or algorithm that could be used to solve the problem rather than a trial-and-error approach;

OR

Explain the advantages to the utility company running the hydroelectric scheme of being able to sell electricity for two hours each day.

The surface area of the reservoir is about 1 km2 and it does not vary significantly as the water level changes.  The utility company that runs the hydroelectric scheme conducted some tests and found a lot of water was lost through evaporation and the quantity lost was independent of usage strategy.

The company are considering installing an array of floating PV panels on the surface to both reduce evaporation and address the imbalance of energy available from the hydro scheme over the year.

The solar energy on 1 m2 of horizontal surface is available from the NASA Surface Meteorology and Solar Energy web site (https://eosweb.larc.nasa.gov/sse/) and the Met Office site can provide the mean monthly temperature (http://www.metoffice.gov.uk/climate/uk/summaries/datasets). The figures for the hydroelectric site are tabulated bleow:

2.1 The empirical equation often used to estimate the rate of evaporation is the Penman formula. Use the simplified form of the equation below to estimate the energy loss per year from the hydro scheme as a result of reservoir surface evaporation:
Q is the total solar energy on 1 m2 of surface in 1 day and is the mean daily temperature for that day in Celsius. Verify the equation is plausible before using it.

2.2 It is decided to float 100,000 m2 of 14% efficient solar PV panels, a tenth of the surface area of the reservoir. Estimate the effect this installation would have on the daily energy production levels. You may assume all the electricity produced is used to pump water back up into the reservoir to raise the level.

There is no need to take the reduced evaporation into account as this was not considered in Part I. You may assume the pumping is 90% efficient.

If the hydroelectric dam were not there the reservoir area could be planted with trees. Sitka spruce grown in that area is known to have a yield of 14 m3 per hectare per year.

3.1 Assess the benefits and disadvantages of afforesting the area. Present your findings as a short report (500 words) with appropriate referencing.

## Report Writing Assignment:

A paper mill has just purchased a 5.7 MW gas turbine for electrical power generation. To increase the overall plant efficiency and reduce the payback time it has been decided to use the exhaust gases to heat water in a heat exchanger. The company requires 12.7 tonnes/hr of steam at a pressure of 18.9 Bar and at a temperature of 315 o C. The temperature and pressure at inlet to the heat exchanger was 29 o C and 0.04 Bar.

The gas turbine exhaust has the following properties:

Table 1: Gas Turbine Exhaust Properties

Design a heat exchanger to fulfil this requirement using the LMTD method. For design purposes assume that the heat exchanger comprises of an economiser, boiler and super heater section. The maximum heat transfer coefficients that can be obtained for this type of heat exchanger design are:

Table 2: Maximum Heat Transfer Coefficients

Initially calculate the product UA for each section, determine the number of tubes and their diameter. The overall tube length in each section should not exceed 4 m.

A pump has been chosen to pump the water and steam around the circuit. The test results are shown below in Table 3.

Table 3: Pump Test Results

The circuit has a static head of 100 m. Using the flow resistance through the superheater and the boiler only, plot the load characteristic in the form H = Z + kQ 2 and hence determine the pump operating point. Find the power required by the pump at this operating point.

The operating point of the pump does not co-inside with the flow rate required in the heat exchanger. What can one do to ensure that they do match?

Describe briefly what is meant by a compact heat exchanger.

## Report Writing Assignment:

Natalie Lawson spent much of her youth playing sports. She passed many hours on the soccer field and in the dance studio. As Natalie grew older, her passion for healthy living continued as she started practising yoga. Now, at the start of her second year in college, Natalie is investigating various possibilities for starting her own business as part of the requirements of the Entrepreneurship program she is taking. A long-time friend insists that Natalie has to somehow include healthy living in her business plan and, after a series of brainstorming sessions, Natalie settles on the idea of operating a smoothie business. She will start on a part-time basis. She will make the product at home, bottle it, and take it to the yoga studio where she exercises because they have agreed to purchase it on a regular basis. Now that she has started thinking about it, the possibilities seem endless. During the summer, she will concentrate on fresh fruit and vegetable smoothies. The first difficult decision is coming up with the perfect name for her business. In the end, she settles on “Healthy Smoothies” and then moves on to more important issues.

During the month of April 2017, the following activities take place:

Apr. 12 Natalie cashes her Canada Savings Bonds and receives \$980, which she deposits in her personal bank account.

13 She opens a bank account under the name “Healthy Smoothies” and transfers \$900 from her personal account to the new account.

15 Natalie realizes that her initial cash investment is not enough. Her mother lends her \$3,000 cash, for which Natalie signs a one-year, 3% note payable in the name of the business. Natalie deposits the money in the business bank account.

18 Natalie pays \$325 to advertise in the April 20 issue of her community newspaper. Natalie hopes that this ad will generate revenue during the months of May and June.
20 She buys supplies, such as protein powder, cups, straws, and fresh fruit and vegetables, for \$198 cash.

22 Natalie starts to investigate juicing machines for her business. She selects an excellent top-of-the-line juicer that costs \$825. She pays for it using her own personal account.

23 Natalie prepares her first batch of smoothies to bring to the yoga studio. At the end of the first day, Natalie leaves an invoice for \$300 with the studio owner. The owner says the invoice will be paid sometime in May.

24 A \$98 invoice is received for the use of Natalie’s cell phone. The cell phone is used exclusively for the Santé Smoothies business. The invoice is for services provided in April and is due on April 30.

28 The yoga studio where Natalie sold her first smoothies orders smoothies for the next month.
Natalie is thrilled! She receives \$125 in advance as a down payment.

PART 1: APRIL MONTH

Requirement 1: Natalie has hired you to be her bookkeeper. Prepare the required journal entries for the above events. Explanations are not required and round to the nearest dollar.
Requirement 2: Post the entries to the general ledger using the t-account format.
Requirement 3: Prepare the unadjusted trial balance as of July 31, 2013.

PART 2: APRIL MONTH END

It is the end of April and Natalie has been in touch with her mother. Her mother is curious to know if Natalie has been profitable and if Natalie requires another loan to help finance her business. Natalie too would like to know if she has been profitable during her first month of operation. Natalie realizes that, in order to determine Santé Smoothies’ income, she must first make adjustments. Natalie puts together the following additional information:

1. A count reveals that \$105 of supplies remain at the end of April.

2. Natalie was invited to deliver smoothies to a summer barbecue at her local community centre. At the end of the day, she left an invoice for \$175 with the facility manager. Natalie had not had time to record this invoice in her accounting records.

3. Because there were so many guests expected to attend the barbecue in item 2, she asked a friend to help with making the smoothies and promised to pay her \$12 an hour. The payment to her friend was made on May 4, 2017, for four hours of work.

4. Natalie estimates that all of her equipment will have a useful life of three years or 36 months. (Assume Natalie decides to record a full month’s worth of depreciation, regardless of when the equipment was acquired by the business.)

5. Recall that Natalie’s mother is charging 3% interest on the note payable extended on April 15. The loan plus interest is to be repaid in 12 months.

Requirement 4: Prepare the necessary adjusting journal entries.
Requirement 5: Post the adjusting journal entries.
Requirement 6: Prepare the adjusted trial balance.

PART 3: FINANCIAL STATEMENTS

Natalie had a very busy May. At the end of the month, Natalie journalized and posted her adjusting entries, and prepared the following adjusted trial balance at May 31, 2017:

Using the information in the adjusted trial balance, do the following:

Requirement 7: Prepare an income statement for the two months ending May 31, 2017.

Requirement 8: Prepare the Statement of Owner’s Equity for the two months ended May 31, 2017,Requirement 9: Prepare a Classified Balance Sheet at May 31, 2017.

Requirement 10: Calculate Healthy Smoothies’
a) current ratio and acid-test ratio.
b) Comment on Healthy Smoothies’ liquidity.

PART 4: CLOSING

Requirement 11: Natalie has decided that her year-end will be May 31, 2017. Prepare closing entries.

## Nursing Case Study Assignment:

Multiple factors influence the care of patients with chronic conditions. As a Primary Heath Care nurse, it is important that care given is prioritised based on both clinical and patient needs. Prioritisation of the patient needs for care is integral to daily nursing practice. This requires integrating and collaborating different aspects of patient needs in order to maximise care activities and the effectiveness of nursing interventions. This case study is designed to demonstrate the integration of various principles of managing care of patients with chronic conditions. Students will be expected to identify and discuss two PRIORITIES OF CARE and apply the clinical reasoning cycle to these as a means of justification. Please refer to the unit outline and marking rubric when writing your assignment.

Case scenario:

Phillip is an active semi-retired person, working part-time in the local specialty tea store. He is married to Klara with three adult children, all of whom live out of home:
Vanessa 35 years old-3 children under 10
Adam 33 years old-new born baby; and
Anton 30 years old with a 1 year-old child.

Each of the adult children is located interstate and has young family. Klara had previously participated in many outdoor activities with her husband and her hobbies include bushwalking, cryptic crosswords and gardening. Phillip and Klara have recently separated and are living separately.

Recently, Phillip has had a number of minor mishaps at work and has been increasingly dropping things. He has been experiencing a slight right-hand tremor and his gait has become unsteady. The tremor appears to worsen at night particularly when sitting down and when resting in bed. Phillip has been increasingly fatigued and forgetful. This was becoming more noticeable and problematic as the tremor did not subside and Phillip felt he was becoming clumsier.

Phillip has been increasingly concerned that he would fall asleep at work so has tried not to sit down unless he is at lunch. It is at work that the hand tremor is particularly troublesome.

Phillip has also had two episodes of losing his balance and once fell over. Phillip also feels as if everything is spinning around and has numbness in his hands. He was also having difficulty speaking and slurring his words. Phillip managed to call an ambulance as he didn’t know what to do. Phillip was reviewed, admitted and seen by a medical officer, and referred to a neurologist for review.

Phillip spent two weeks in hospital and a provisional diagnosis of Parkinson’s disease was made. To rule out any other neurological conditions a series of investigations was conducted including an MRI and PET scan as part of the diagnostic screening process; no abnormalities were detected. Following these investigations and a thorough neurological exam, a firm diagnosis of Idiopathic Parkinson’s disease was made.

Phillip was discharged home, being collected by Klara. Klara indicated that she would not be able to be Phillip’s carer, Phillip was adamant that he would be fine at home on his own. You have been asked to see Phillip in the community as part of his discharge plan.

Symptoms experienced:

Intermittent fatigue for approximately 8 months.
Phillip has been increasingly dropping equipment and stock at work.
He has been unable to deal with hot water at work and was not able to make tea to serve as samples.
Increasing hand tremor for 4 months, most evident at rest.
Emotional lability for 4 months with out of proportion emotional reactions to small incidents.
Unsteady gait for approximately four months including stumbling without cause
Increasing levels of confusion;
Increasing drooling;
Increasingly being told he is hard to hear;
Increasing nausea.

### Exploring & Visualising Data: Descriptive Statistics & Plots- Statistical Analysis Assignment

Internal Code: MAS7294

## Statistical Analysis Assignment:

The spreadsheets provide information for 338 houses. Variables in the dataset include:

• The housing ID
• Region by postcode
• Distance from city in kilometres
• Number of rooms
• Type: Detached (1) Semi-detached (0)
• Age in Years
• Price in Euros

Your task is to “get a feel” for what is going on in this particular housing market. In particular, we want to use simple descriptive statistical techniques as well as plots and graphs to get a first understanding of which variables are likely to influence house prices.

You will, therefore, replicate some of the basic techniques that every marketer needs to know:

1. Create one or more pivot table that shows
(a) the average house price by type of house;
(b) the average price of house by number of rooms;
(c) the average house price by postcode. What do you find?
2. Visualise the pivot table using appropriate plots
