Technology in Practice Part II: Intra-Aortic Balloon Pump Background of Technology Before tThe intra-aortic balloon pump (IABP) became a successful piece of technology‚ it was first introduced by Harken in 1958 in hopes of treating left heart failure (IABPumpers‚ 2006). Harken thought that by removing a certain amount of blood from both femoral arteries during systole‚ and rapidly replacing it during diastole‚ he could augment the cardiac output and increase coronary perfusion.

Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

For our group project‚ we chose to create a parody of the short-story “Button‚ Button”. We thought it was best to stick somewhat to the original story. We kept the button aspect of it‚ in which we used a stapler to add a humorous effect. We also decided to keep a form of Mr. Stewart in our story‚ but instead we renamed him “Mr. Predabutn”. We did remove Norma from the story‚ mostly because a lack of actors‚ but also to keep the story a lot simpler. By no means‚ though‚ did we forget about Arthur

UFO or NASA weather balloon? There is a wealth of UFO sightings around the world. There is also always someone around to see it. These videos are full of shaky footage and interesting commentary. It could be a UFO? And the video is put to the test through peer evaluation‚ usually on YouTube. Rational folk always have an answer. A drone. Trump flying around with bat wings. Or a more simpler explanation‚ a NASA weather balloon. It would be difficult to dismiss the chance that a real UFO has been caught

cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct. Baking soda mixed with vinegar and lemon juice caused the balloon to expand. There was no reaction with the balloon when the baking soda was poured into the water or oil. The moment the baking soda hit the vinegar and lemon juice‚ the balloon started
