Today we visited BTEC and learned more about Chromatography. Chromatography is the process of separating different pieces. To exemplify this we separated different pieces of the grape soda. We separated blue and red die and the soda. We then took a tour of the lab in which we saw different sizes of trains which they use. She told us about programs that they support and that many companies use the facilities to contract out work and to do training. Students are able to minor and get hands on training on industry equipment. They set up their facility similar to what they would see in a company so that they would be able to know going into a job industry standards on cleanliness.

In the afternoon, we prepared our 3d prints for use. We sanded down some of the corners of the 3d print so that it wouldn’t hurt the rabbit. We then opened back up the rabbits. We checked the fit of the prosthetics and found that it was a perfect fit. We use super glue to attached the prosthetic to the bone. It took a couple of times but it finally stayed in place. We continued to practice our suturing on the rabbits and were able to close the abdominal cavity and stitched the skin close around the rabbit. We got a lot better at stitching with the amount of stitches it took to close the rabbit. It took three rethreaded needles to sew the rabbit closed. With the bones in the way we were unable to close the thoracic cavity. In the end the rabbit was completely covered by its skin with some stitches. With a couple of stitches over the knee it looked good as new and was completely functional. The knee replacement was a complete success. We then watched a part of a cancer documentary that retold the story of a 14th month child diagnosed with Leukemia. The documentary also told of how over a couple thousands of years we have figured out what makes us sick and what cancer is. It was interesting to hear that at one point in time you never heard about cancer and no one survived. Thanks to the work of wealth socialite, she was able to raise money for research and make it a priority for the nation.

Today we went to Dr. Grifths lab on UNC campus. We heard them speak about some of the work that they have been doing. They presented some photos of DNA and mitochondria. We learned about how they prepare the cells for viewing under the microscope where they cut the cells. They also showed us two of their microscopes and let us try using them. They also demonstrated the process for cutting the cells under a microscope. Dr. Grifth showed us one of the microscopes that he built himself.

Our group found it interesting how strong and how much connective tissue there was. It was also cool and creepy when the skin was all the way off because it is an unusual sight. Our group found it difficult to not break the muscle bellow while pulling hard to break the connective tissue this was not helped by the amount of fat our rabbit had. The amount of fat hidden inside the skin was surprising to us because the rabbit was fairly small and it was not a large factor in the demonstration. We also were surprised to see that the heart was so small compared to the rest of the body. Our group is excited to see the actual internal organs of the rabbit as today we mostly tanned the rabbit.
