Non Destructive Testing

* Rubbing alcohol (or isopropyl alcohol) is flammable, so be sure to keep it away from high heat or heat sources.

The first norm I violated was sitting with my own “clique” during lunch. This is more than common in high schools and even middle schools. In regards to social control, this norm creates a spot in society for an individual, giving them a sense of belonging. This sense of belonging leads to self-assigned seats and allows people with similar interests or ideals to be better connected. To violate this norm I sat with people who did not know who I am without asking prior to sitting down.

After the trial ran for 10 minutes, we measured the distance travelled by the solutes and the distance travelled by the solvent. The distance the solvent travelled was 5.3 cm. The unknown solute travelled 4.1 cm, the Vis-a-Vis solute travelled 4.9 cm, the sharpie solute travelled 5.4 cm, and the Just Basic solute travelled 5.3 cm. By dividing the distanced travelled by the solute by the distance travelled by solvent we calculated the Rf value for each pen type. The unknown had an Rf value of 0.77, the Vis-a-Vis had an Rf value of 0.92, the Sharpie had an Rf value of 1.0, and the Just Basic marker had an Rf value of

Thin Layer Chromatography (TLC) works in relation to the polarity of chemicals. A plate is first covered with aluminum foil or silica etc. and has solutions of varying polarities placed upon the aluminum foil or silica. When placed in a in a puddle of solvent that moves up the plate, the different inks i.e. the solution will move up the place based on their Rf values. Adherence increases with increasing polarity, so the less polar compounds will be carried farther by the solvent. Eventually the dyes will separate into their compontnets, which can be visibly seen. This is then used to determine who the ink of the unsigned note belonged to along with the pen that it belonged

Dissolve 40g povidone in 120g water. Blend 200g lactose, 4g Blue#1, 0.8g Yellow #10. Screen rough blend for clumps and blend to uniform color. Add povidone solution to povidone and 515.2g lactose to granulate. Add water to appropriate consistency, then dry product to specification. Sift material to correct fleck size (wet granulation of coating). Blend 450g of sodium glycolate to 20g silicon dioxide. Screen material. Blend 2700g starch, 7980g MC, 50g Mg stearate, 800g of blue granulation (above) (press coating). For the core, blend 2675g cyclophosphamide monohydrate to 5g silicon dioxide, blend with 1150g starch, 150g starch glycolate, and 20g magnesium stearate. Compress core, then surround core with coating by second direct compression. Hardness

10.) Use a clean spatula to place a small amount of the sample from the crime scene into wells J,K and L. Record any physical properties of the sample that you observe.

The purpose of the lab is to perform series of tests to determine the physical and chemical characteristics of several unknown powders, and then use that information to classify the unknown powders.

After putting the CH2Cl2 to a beaker containing the drying agent anhydrous sodium sulfate, a sticky white solid was recovered.

The author Joelle Charbonneau wrote the book The Testing. An amusing fact about Joelle is that she taught many students how to sing. In an article Joelle states “My students are a wonderful source of inspiration and continue to teach me life while I teach them about singing” (Charbonneau… New York Times). The Testing by Joelle Charbonneau is about a girl named Cia who is selected to go through a testing program to test her knowledge and see if she can attend a certain college. Cia has many roadblocks, but that does not stop her from doing her best. People should recommend this book because of its connection to the article titled New Surveillance Technology. The message of this book is that knowledge is power, so don’t betray it.

to compare the results, and neither solution was expected to produce an observable chemical reaction. The procedure was the same as used for the test with 6M HNO3 and 0.1M AgNO3 solution and the test with 6M HCl and 0.1M BaCl2 solution. A third experiment used was the flame test. First, a scoopula was used to place 0.1 grams of the unknown compound in a test tube, and a wash bottle was used to add approximately 2 mL of deionized water to create a solution.

Samples were collected from the tabletop, the camera, the window and the refrigerator door. The samples, were then placed in the petri dish, in its designated segment. The other petri dish had samples from the mirror, the stethoscope, the doorknob, and the steering wheel of the car.

Tested in Every Way: the Catholic Priesthood in Today’s Church, written by Christopher Ruddy, is a report and at the same time a reflection on the Seventh Annual Cardinal Bernardin Conference which was held in the Oblate School of Theology in San Antonio, TX in 2003 . Ruddy reports the voices of academic and pastoral expertise sharing about the challenges and the identity of being a priest. Besides of giving a report, the book opens up and finishes with the Ruddy’s insightful reflections.

- Disfigurement or injury by removal or destruction of a conspicuous or essential part of the body.

This is done to evaporate the solvent leaving the white powder of ephedrine or pseudoephedrine.

The next step was to place the strip of chromatography paper on a paper towel. Then dip a capillary tube into the plant pigment extract (spinach pigment extract) provided by the teacher. The tube will fill on its own. We applied the extract to the pencil line on the paper, blew the strip dry, and repeated it three to four times until the line on the paper is a dark
