Fingerprint Assignment

In 1978, Carroll Bonnet was stabbed to death in his apartment. Police collected evidence, including latent fingerprints and palmprints from the victim’s bathroom (officers believed the killer was trying to wash off blood and other evidence before leaving the apartment). The victim’s car was then stolen.

The car was found in Illinois, but after collecting additional latent prints, investigators couldn’t develop any new leads. The crime scene evidence was processed, and latent prints recovered from the scene and the car were searched against local and state fingerprint files. Investigators also sent fingerprint requests to agencies outside Nebraska, but no matches were returned and the case soon went cold.

I chose this article because I found it interesting that no one could figure out who the culprit was until looking back at the case and matching fingerprints with already convicted felons.

Vehicle Safety

I'm Volvo V40 Hatchback -

1. Structure:
Seven percent of the safety cage in the original V40 was made of hot-formed boron steel. The structure in the upcoming cars built on the new Scalable Product Architecture (SPA) feature over 40 per cent hot-formed steel, which translates into significantly improved strength but without adding mass or weight.

2. Safety Features:
 It's major two safety features are known as "world-firsts": auto braking when turning in front of an oncoming vehicle and run-off-road protection.

3. Technological Features For Safety:
Volvo has technology that can protect pedestrians, and self steering system that's designed to stop cars from running off the road.

The Future of Transportation - Article Review

http://www.citylab.com/tech/2014/09/los-angeles-is-building-an-e-highway/380914/


In Los Angeles, they are building a highway called the E-Highway. Which will eliminate truck emissions. Specially outfitted hybrid or all-electric trucks can attach to the system using automated current-transfer devices called pantographs. Once connected, the trucks will pull all their power from the overhead lines, effectively becoming emission-free vehicles.

Past & Future Methods of Transportation

First Helicopter Paul Cornu - 1907

I was interested in this aircraft because it was an open-framework structure built around a curved steel tube that carried a rotor at either end, and the engine and pilot in the middle. Power was transmitted to the rotors by a drive belt that linked both rotors and spun them in opposite directions. Control was to be provided by cables that could alter the pitch of the rotor blades, and by steerable vanes at either end of the machine intended to direct the downwash of the rotors. The way it was built was very simple and I was surprised at how well it worked. 


This updated future aircraft design concept from NASA research partner Lockheed Martin shows a few changes from another concept seen eight images earlier in this gallery. It is a good example of how simulations and wind tunnel tests, conducted over time, generate data that tell researchers how to improve a design to achieve goals. The goals for a future supersonic aircraft are to produce a much lower-level sonic boom and to reduce emissions. The ultimate goal is to achieve a low enough boom that a current ruling prohibiting supersonic flight over land might be lifted.

Paper Airplane Challenge


The plane closest to you is the distance plane, and the plane farthest is the time plane. 

The four forces that are acting on the plane include thrust, lift, drag, and weight. 

Longest distance was one meter, flight time was three seconds. 

Boat Building

1.

2. The boat took 80 coins to sink 

3. I would probably have made my boat more sturdy and more easily floatable than I did.

Science & Tech - Chemical Safety Research

Mercury:
  1. Mercury can be used to make thermometers, barometers and other scientific instruments. Mercury conducts electricity and is used to make silent, position dependent switches. 
     The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.
    Mercury can be handled safely by a professional chemist, although you should minimize or eliminate its use whenever possible.

Science & Tech - Interim Report

Work Habits:
My attendance is not the best, but when I am in class I don't arrive late and I have all my supplies with me. I would say 50 percent of the time I focus on my assignments and the other half I have trouble concentrating. When we are in the lab I always follow all the safety rules. 

Assignment Completion:
All of my assignments have been completed besides a lab I missed during class and the Chemisty project blog post.
The reason why I have not complete the Chemisty project is because it seems to be one of the hardest assignments we have been assigned.

Assignment Quality:
I believe I am showing my learning in all my assignments because all my marks are either a high B or an A. I am happy with the quality of my assignments. I would say my best assignment would be the WHMIS booklet because I got perfect on it. 

Plan For Success:
Three specific things that I need to work on would be using my class time effectively, attending class regularly, and paying full attention during class. 

Work Habit : Good

Part 2:
Empty aerosol cans are safe for the trash; Leftovers should be brought to your Household Hazardous Waste Collection Site
Empty cleaning products can be recycled or discarded with other household waste. Unused amounts of cleaning products can generally be safely disposed of down the drain or in the trash. That's not the case with all products found around the home. For those products that do require special handling, such as solvent-based paints, used motor oil and certain pesticides, household hazardous waste collection programs are an important resource
Chemicals in illegally disposed hazardous waste can be released into the environment and contaminate our air, water, soil, and possibly the food we eat, potentially causing serious health problems in humans and wildlife.

Air Freshner -

1. Glade
Febreze
2. The active ingredient in Febreze is hydroxypropyl beta-cyclodextrin (HPβCD). 

3. BHT - Known as a neurotoxin, endocrine disruptor, immunotoxicity, non-reproductive organ system toxicity, skin eye and lung irritator 
Acetaldehyde - Known to cause cancer, toxic to reproduction and development, immunotoxin, non-reproductive organ system toxin, skin, eye and lung irritator

4. They contain volatile organic compounds (VOC’s) called 1,4 dichlorobenzene(1,4 DCB) which cause soil, groundwater, as well as air pollution. 

5. Air fresheners contain a variety of ingredients, some of which may be harmful if swallowed. They also may be irritating to some people. Use only in a well ventilated area. 

6. Use up the air freshener in its entirety before disposing. Recycle the empty vessel. If you have not used all of the air freshener, bring it to your local community collection center. 

7. Rather than masking odors with other, more potent odors, or disabling your sense of smell all together, there are ways to absorb unwanted odors. Sodium carbonate (otherwise known as baking soda) has been safely used as an odor sponge for generations with no known ill effects. There are also ways to employ specific types of charcoal products to scrub unwanted odors from indoor air. You
