Visualizing Healthcare Data with Tableau (Toronto Central LHIN Presentation)Stefan Popowycz
This is the presentation I gave to the Toronto Central LHIN about using Tableau to visualizing healthcare metrics (April 16 2013). I also have a section on how Information Design best practices can be leveraged in order to effectively communicate your key messages to your end users.
A presentation outlining the method of colorimetry & spectroscopy. Also detailed information regarding spectrophotometer, calculation of absorbance and transmittance according to Beer & Lambert's law
It is the most common analytical technique used in biochemical estimation in clinical laboratory.
It involves the quantitative estimation of color.
A substance to be estimated colorimetrically, must be colored or it should be capable of forming chromogens (colored complexes) through the addition of reagents.

Guidelines for Lab Report
Lab 2: Quantification of Protein (Bradford Assay)
Your report for Lab 2: Quantification of Protein (Bradford Assay) is due the week of October 7/8/9/10. Please include the following information in your report:
Hypothesis: as usual
Introduction:
• Background/theory of Bradford Assay
• Purpose of the experiment
Results:
In addition to the specific data discussed below, your Results section should always include one or more paragraphs of text that provide:
• A brief description of the procedure
• Explanations of any charts, graphs, figures, or calculations that are included
• Statements about the most interesting/noteworthy data
Data:
1. Table of measured absorbances (like Table 2 on p. 31).
2. Table showing protein concentrations of unknowns (like Table 3 on p. 31). Say which unknowns—1, 2, or both—you used.
**Please re-make the tables for your report. DO NOT simply tear out p. 31 from your lab manual and staple it to your report.
3. Standard Curve:
• Label with title and caption
• Label axes: x-axis = Concentration (μg/ml); y-axis = Absorbance at 595 nm. Be sure to include units on Concentration. Remember that absorbance (optical density; OD) has no units.
• Plot points, leaving room to plug in your unknown absorbances to find their concentrations
• Connect the dots
(Note: Do NOT draw a straight line—unless your data really looks like a straight line. The samples we measured did not fall into the “linear range” of the spectrophotometer, and everyone’s data that I saw flattened out a lot at the high concentration end of the range. Connect your data points with a curve.)
• Indicate by drawing horizontal and vertical lines how you found the concentration of your unknowns.
Discussion:
• Did your results match your expectations? If not, why not?
• Did you have any difficulty finding the concentration of any of your unknowns?
• Do you think your measurement of protein concentration was accurate? Did your duplicates agree well? For your standards, did your absorbances increase as your protein concentrations increased?
Conclusion: as usual
Lab Report Rewrites
You may rewrite TWO of your first FIVE lab reports in an effort to improve your grade.
You do not need to rewrite the entire report; just fix the problems that caused you to lose points the first time around.
You MUST hand in the original version of your report along with your corrected version. If you do not have the original attached, we will not accept your rewrite.
Your final grade on the rewritten report will be ...
Today’s laboratories want more from their liquid chromatography system: Higher performance. Better reliability. More consistent and comprehensive analytical workflows. And most of all, more predictable and reproducible results. At the same time, you want

2. DATA LOGGING
Theprocess where computer used
to collect data through sensors,
data analyzed and saved, and the
results of the collection and
analysis become the output.
The data logger is the electronic
instrument that records the
measurement over time.
4. Sensors
- Sensor is device that Computer
measure physical - used to record the
quantity and send the data and display the
data in terms of data as table or
voltage to the graph by using
computer to represent specific software
the quantity
Interface
-used to connect between sensors and
computers,
-responsible for converting the voltage from
sensor into digital voltage that can be read by
the computer and prevent excessive voltage that
can damage the computer
5. ADVANTAGES AND
DISADVANTAGES
Advantages Disadvantages
1. New innovative 1. If the data logging
experiments and equipment breaks down,
dangerous some data could be lost

as there is no expensive even if it is
possibility of human just for a small task

3. Caused loss of
3. Easier to understand conventional methods of
scientific data collection and
experimentation and reduced the practice of
scientific concept, and graphing skills
better graphing.
7. What we know about acid and bases?
Acids
- Level of pH: 1 to 6
- Example: Lemons, orange juice and vinegar are
examples of acids.
Bases
- Level of pH: 8 to 14
- Example: Mustards and medicines are examples of a
base. Flavor is added to medicines to offset the bitter
taste.
Water
- Level of pH: 7, Natural
12. QUESTIONS
1. What does the graph tell you about the amount of
hydrochloric acid and sodium hydroxide needed for
the titration?
2. What does the first derivatives graph represents?
3. Explain the difference between an endpoint and
equivalence point in a titration.
4. Can we titrate a solution of unknown concentration
with another solution of unknown concentration and
still get a meaningful answer? Explain.
5. What is the chemical equation involved in this acid-
base titration?
13. ENHANCE
1. Citric acid
- Plays a role in one famous stomach remedy, or
antacid.
- Antacids are more generally associated with alkaline
substances, used for their ability to neutralize stomach
acid.
Example : The fizz in Alka-Seltzer;
14. 2. Aluminum hydroxide
-Is an interesting base, because it has a wide number of
applications, including its use in antacids.
- It reacts with and neutralizes stomach acid
(Hydrochloric acid, HCl).
Example: found in commercial antacids such as Di-
Gel™, Gelusil™, and Maalox™(relief of heartburn and
acid indigestion).
16. 3. Baking soda (sodium bicarbonate and sodium
hydrogen)
- Use in baking and other application such as in Alka-
Seltzer (addition of citric acid to improve the flavour),
fighting fires (smoothers flames by obstructing the
flow of oxygen to the fire)
- Baking Powder = Baking soda + weak acid = carbon
dioxide
(causes dough and batters to rise)
17. QUESTION :
Why Stomach Acid might need to be neutralized?
substance inside the body that is able to digest the
living tissue around itrequire some of it to be
neutralized.
when the acid leaks upward through a valve into the
oesophagus, causing what is known as acid reflux or
heartburn.
heartburn is when the stomach acids get into the
oesophagus and eat away at the lining, causing a
burning sensation in the chest and throat.
to reduce the leakage of stomach acid into the
oesophagus, neutralization of some of the acid would
be required, avoid the oesophagus receives permanent
damage. In order to do this antacids
