Potential energy

The authors created the Accelerated Sensor of Action Potentials 1 (ASAP 1) using a green fluorescent protein source on the extracellular side of the plasma membrane to highlight the membrane potential changes as demonstrated by the fluctuation in the fluorescent brightness. Neuronal action potentials generated are monitored up to 200 Hz in frequency using this device. The general purpose of this experiment was to further understand information processing in the brain and how brain activity is…

resistance in disordered metals, variation in density of states in semiconductors and MOS structures. The noise resulting from these transitions has 1/f spectra.8 Figure 1.4: Two well potential of a two level tunneling system The SNR associated with flicker noise is given by, SNR = q ncΩ γHln( fmax fmin ) Where fmax and fmin are the limits of measurement frequencies. The SNR is independent of applied voltage or current. If 1/f noise dominates…

This experiment’s aim was to find the alcohol with the highest energy output when burnt using specific heat capacity of calorimeters. This data gathered only partially supported the hypotheses stated. There is an apparent trend between the heat energy of the alcohols and the amount of carbon atoms in the alcohols in the graphs shown. The first experiment (first graph) shows the results of the tests with a controlled calorimeter height of 20 centimeters. This means that the calorimeter, rather…

let the the person know they are cold. Dr. Richard L. Mueller defines TRPM8 as "an ion channel, upon activation it allows the entry of Na+ (sodium) and Ca2+ (calcium) ions to the cell that leads to depolarization and the generations of an action potential." In other words the TRPM8 cells open for sodium and calcium. However, in an article by Matt Soniak, he states that the TRPM8 ion cells don't only open to Na+ (sodium) and Ca2+ (calcium), but certain natural chemicals can activate TRPM8 on…

Rankine cycle Figure 2: Rankine cycle As mentioned earlier, the Rankine cycle also includes the possibility of superheating the vapor, as cycle 1–2–3–4–1. If changes of kinetic and potential energy are neglected, heat transfer and work may be represented by various areas on the T–s diagram. The heat transferred to the working fluid is represented by area a–2–2–3–b–a and the heat transferred from the working fluid by area a–1–4–b–a. From…

the body using electrical synapses. While neurons are made up off a cell body referred to as the soma, dendrites, and axon. Nerves consist of axons and sometimes nerve fibers, and each of those axons has the ability to produce an action potential. Action potential is a well-preserved message as a response to a specific stimulus that travels down the axon. Moreover, sodium/potassium pumps are located in the…

Elizabeth. An energy crisis has emerged. Solar energy, though right now unreliable, has the potential to be an answer to this crisis. Solar energy defined…

foods, and 2000 calories worth of healthy food, they both contain the same raw energy. If that's true, then why should you select the healthy option? That’s where nutrients come into play. Nutrients come in six parts, carbohydrates, proteins, fats, vitamins, minerals, and water. The first three in the list are classified as macronutrients. That means we eat them in fairly large quantities, and they contain the energy (calories) we need to get us through our day. The other three are…

The difference between nature and nurture is that nature is the idea that behavior is effected by your chemical and gene make up while nurture is the idea that you are a blank slate and your behavior is distinguished by experiments. They both effect behavior is what was discovered. * Dualism is supported by cognitive psychologists such as George A. Miller and Sigmund Freud * Rene Descartes dealt with Monism vs. Dualism & Interactive Dualism * Monism is the belief that the mind…

Achievement Standard 90936 Credits – 2 Title – Physics in Action Introduction The refrigerator is a common household appliance that is an essential food storage technique in developed countries; it is made up of compartments which are thermally insulated and also has a heat pump which can be mechanical, electronic or chemical. The heat pump is a device which transfers heat from the interior of the fridge to an external environment, this means that the fridge is cooled to a temperature which is…
