You should read chapter 3 (Osteogenesis Imperfecta) from your Clinical Studies in Medical Biochemistry textbook (by Rosenthal and Glew) then answer the following questions;

1.Why is a bluish discoloration of the sclera a common finding in type I OI ?

2.Examination of type I collagen from a patient with type IV OI revealed normal electrophoretic mobility but altered thermal stability. Which region of the molecule is likely to contain the mutation ?

3.Why do mutations in C-propeptides cause significant posttranslational overmodification of type I collagen ?

4.Why does a reduction of collagen thermal stability by 6°C prevent incorporation of the corresponding mutant molecules into bone matrix ?

5.A teenager with a history of fractures but no skeletal deformities and no acute dis- tress was diagnosed with moderate type IV OI. After learning that radiographic analysis revealed low bone mineral density in their child, the parents inquired about a possibility of bisphosphonate therapy.

Introduction

Spreadsheets have a wide variety of uses in both the business and academic worlds. The study of

physics is no exception to this, and spreadsheets are a useful tool in the laboratory for both modeling

and computation. This lab will introduce you to the spreadsheet program Microsoft Excel and will

provide you with an opportunity to use what has been learned.

Equipment/Supplies

1. Computer equipped with Microsoft Excel software

Section 1

This section contains basic information and terminology regarding the use of spreadsheets. It is

intended for those students who have no previous experience working with spreadsheets. For those

students with a working knowledge of spreadsheets, this section can serve as a review.

Basic terminology

1. A column is a complete vertical set of cells. It is designated by a letter .

2. A row is a complete horizontal set of cells. It is designated by a number.

3. A cell is one item in the spreadsheet. It may contain text, a number, or a function. It is identified by a

letter/number pair (e.g., A2 or DD38), where the letter is the column and the number indicates

the row.

4. A range is a set of cells that may be horizontal, vertical or rectangular. It is designated by the first

and last cells in it, separated by a colon (:).

5. A function is literally a mathematical function. It may contain numbers, operators, basic functions,

and references. Note: a function must always start with an equals sign.

6. An operator is one of the familiar mathematical operators: +, –, *, /, and ^.

7. A basic function is also from math, examples are sum(), exp(), sin(), atan(), and sqrt().

8. A reference is the value in another cell, named by its column and row as a pair, e.g., A1 or D3.

References will often serve as the “variable” in our functions.

9. Syntax for special functions:

Function Excel notation Syntax

p PI() p/2 => PI()/2

exponential EXP(x) ex = EXP(x)

Scientific notation 3E-3 3×10-3 => 3E-3

Numbers or expressions as text Enclose in quotes “sin(PI()/2)+6”

Physics 251 Laboratory Spreadsheets Fall 2002

In the figure above several cells are shown as examples. Cell A3 has text typed into it. Cells C3 and E3

have constants (numbers). Cells D3 and F3 have functions. The text in cells C4:F4 shows how the

functions and constants in row 3 were typed (without the quotation marks, though). There are entries

in range C3:F3. There are no entries in B1:B4. The entire area shown is A1:F10. Note that for

rectangular ranges the first and last cells are the upper left and lower right respectively.

To enter information in a cell just click in it and start typing. What you type will appear in the cell and

on a line near the top of the window (Edit Bar). If you need to edit what you have typed, work in the

Edit Bar. Use the mouse move the cursor around in the Edit Bar, the arrow keys will not work, as

these will move you to a new cell. If you type a function, the function will be evaluated when you hit

return (or arrow to a new cell).

You can highlight a cell with a function in it, click and hold the little box in the lower right

corner and drag. This will “fill” a whole range with the equation you want, furthermore, the

spreadsheet will automatically increment the row # or column letter as it goes.

The example above shows the usefulness of automatically incrementing rows. In cells A2 & A3, I typed

the numbers 1&2. Highlighting both cells and dragging the corner down I get a list of counting

numbers. In cells B2 and B3, I typed the dates for two consecutive Wednesdays. Again, highlighting

both and pulling down I get a column with the dates for the next 5 Wednesdays. Incrementing can be

done with formulas as well. In cell C2, I typed in the equation =A2^2+3, then “pulled down” to

calculate the equation for all the numbers in column A. Double clicking on a cell shows the function.

Physics 251 Laboratory Spreadsheets Fall 2002

Note that when I pulled down, the spreadsheet automatically incremented the index from A2 to A6.

Sometimes we do not want the cells to increment automatically, to prevent the spreadsheet from

incrementing use a ($) before the column letter to stop columns from incrementing or before the number

to prevent the rows from incrementing. If you are using a cell to store a constant, put ($) before both

the column letter and the row number.

Using only the ideas mentioned so far, we can already get a glimpse of how to do physics with a

spreadsheet. In the following example, it is illustrated how to calculate a basic 152 problem: the height

of a ball that is thrown upwards with initial velocity v0. We remember the kinematic formulas for the x

and y motion of an object subjected to gravitational acceleration as 2

0 0

2 y = y + v yt + ayt and

0 0x x = x + v t .

To plot the function, highlight the numbers in columns B and C, click on the chart icon on the toolbar at

the top, select XY Scatter plot and click OK. The right column will be used as the independent variable

(x) axis and the column on the left will be used as the dependent variable (y) axis. Adding a trendline

and displaying the equation on the graph are options in the chart menu.

Section 2

In this section, you will apply the information in section 1 to create several spreadsheets.

1. Create a spreadsheet that reproduces the ball thrown upwards as in the example in section 1 but on

this spreadsheet add x motion to it. Remember to add constants for initial x velocity and position.

Make plots of x vs. t, y vs. t and x vs. y

2. Make a spreadsheet that produces a “wiremesh” plot of the potential of a dipole. Remember the

equation for the potential of a dipole is

è ø

.

Steps:

1. Keep everything in the region of the x-y plane bounded by x = [-2,2] y = [-2,2].

2. Offset your grid so the charges don’t sit precisely on grid points. Set your first point at

(2.001,2.001).

3. Set up constants, k=9e9, q1, q2, x1, x2, y1, y2 (the charges and locations of your two charges)

and delta (the step size in x and y – should be between 0.1 and 0.3).

4. Create a horizontal range representing x values.

5. Create a vertical range representing the y values.

6. Create a formula that will calculate the potential due to q1 at the origin. Fill your x-y region and

check the results. Check to be sure the automatic increment feature is working the way you

want it to.

7. Modify your formula to move q1 to a value on the +x axis, recheck. Does the graph make

sense?

8. Now, modify to move q1 to a point with positive x and y, recheck. Does the graph make sense?

9. Add in the other charge.

10. Excel has a “surface plot” feature in the chart wizard.

11. Plot and print wiremesh plots of your charges in quadrants I &III and I &II.

The following is an example of a wire mesh plot with charges at (0.5,0.5) and (-0.5,-0.5).

1. Respond to the following in a minimum of 175 words:

Search for a criminal justice-related case study that gives examples of how forensic science contributes to the criminal justice process. You may use current events, books, the internet, etc. Briefly describe the circumstances and then give a synopsis of a way in which forensic science was or is being used in the case, either in evidence collection, laboratory analysis, or otherwise.

2. Forensic science plays a major role in solving crime. The field of forensic science spans multiple disciplines. Over the years, as technology has advanced, the capabilities of forensic science units have increased. The purpose of this assignment is to show that you understand the scope of work in forensic science.

Write short-answer responses between 100 and 225 words each in response to the following:

• Describe the evolution of forensic sciences over time, including the role of key pioneers.
• Differentiate 2-3 of the 11 forensic science disciplines outlined in this week’s reading used to aid law enforcement officials in conducting their investigations. Provide examples of their scope of work and the role it plays in criminal investigations.
• Explain how forensic science is used in the criminal justice system.

Cite the sources used to support your assignment.

Note: In the criminal justice field, your written communication skills are paramount since much of these career options require report writing. Be certain to follow the rules of grammar so that flow of thought is maintained for the reader.

Operations Management and Factors Affecting Productivity (100 points)

Maduro Cleaning is a small organization that provides cleaning services to both residential and commercial clients. As a small organization, the owner assigns crews of two, three, or four employees to jobs each morning but the owner does not have a good method of determining a reasonable amount of time that each cleaning should take. The owner decided to keep data on job times and crew sizes in the hopes of developing a productivity measure.

Address the following requirements:

• Calculate which of the crew sizes has the best productivity per worker, and explain your method.
• Evaluate your outcome and the possible reasons that would explain those results.
• Project what the productivity might be for a crew size of five and explain your reasoning.

Crew Size Avg: Productivity per Crew

• 2: 3765 square meters per day
• 3: 4915 square meters per day
• 4: 6309 square meters per day

Directions:

• Your essay is required to be four to five pages in length, which does not include the title page and reference pages, which are never a part of the content minimum requirements.
