...Lab Write-up for Lab #7 CATHETER MODELING BioE431 Abstract Catheters have many uses when it pertains to medicine, a simple design that consists of a long narrow tube connecting to the body externally or internally and the other end to an apparatus or module. It is a negative system meaning the catheter is always connected at both ends making it a closed system. This setup can be / is being used for medicine delivery, fluids input and output, measuring volume displacement and many other operations. We are constructing a similar catheter module to measure and display a step response to a catheter loosing its negative/closed environment. To achieve this data we have a tube filled with water connected to a pressure sensor that doubles up as a transducer converting the pressure change as an electrical signal, which via software is being graphed. The other end of the catheter is connected to a funnel with a balloon atop and this funnel is junctioned using a 3-way stopcock. The tube is filled with water end to end, the balloon attached on the funnel is blown up which in turn puts pressure on the water which puts pressure on the pressure sensor, that transudes the pressure difference in to an electrical signal and LabView software displays that signal as a graph. Documenting and analyzing the step input when the balloon is popped is the purpose of this lab. Introduction The purpose of this lab is to build a catheter system, with an inflated balloon applying pressure to the...

...Biotechnology Incorporated: Is expansion to Germany a good or bad ideal? At Biotechnology Incorporated we are looking towards globalizing our organization into other parts of the world. One of the countries that our organization Biotechnology Incorporated are considering expanding to is Germany. In this report I will go over the different factors such as the economy, political influences, language, culture, and cost of doing business in Germany. From the research I will gather I will give my opinion on wither Biotechnology will benefit from opening an office in Germany and the type of operation we will chose to do business in Germany. Germany and the Economy The Federal Republic of Germany is the European Union’s most populous country, the EU’s largest economy and the world’s fourth largest economy.8 According to the IMF, Germany has achieved a GDP of $US3.4 trillion in 2011, and enjoys a relatively low unemployment rate of 5.7% which is significantly lower than most EU countries.8 Germany’s economy remains strong, focusing on service sectors, science, technology, and specialized manufacturing and engineering. Germany is also a global leader in the development of environmental technologies, with a focus on energy efficiency and sustainability of resources. In Germany the biotechnology sector is growing at a steady pace. The reason for this growth is because biotechnology has become the basis and driving factor behind many applications in medicine, the food and feed...

...Lab #12. The Nervous system. Sensorimotor transformations. EPPS BIOE 2101 Spring 2016 INTRODUCTION The nervous system “is” you. Nervous cells transform signals from the outside world into “spikes,” voltage changes, or chemical signals, perform transformations on these signals, and then may turn on muscles. Muscles, in turn, cause behavior: a smile, or moving across the room. Your nervous system is responsible for your interaction with the world, from sensing it to acting upon it. | Parts of the nervous system: the spinal cord, motor neurons, and sensory neurons. Sense organs in muscles transmit sensory information to spinal cord interneurons, that connect to motor neurons, that in turn activate muscles. (Adapted from Kandell et al., 2000). | | Parts of the nervous system: the spinal cord, motor neurons, and sensory neurons. Sense organs in muscles transmit sensory information to spinal cord interneurons, that connect to motor neurons, that in turn activate muscles. (Adapted from Kandell et al., 2000). | Neurons – The cellular building block of the nervous system is the neuron. These cells are typically excitable: they can “spike,” a process by which their membrane voltage quickly changes, and they transmit information. Neurons can transduce signals from the outside world into spikes, transmit spikes to each other via connections called “synapses,” and connect to muscles, in order to turn the muscle on and make it contract. When spikes happen in neurons...
