1. What questions (hypotheses) are addressed in the paper? Look in the Abstract.
Can we calculate the equilibrium for the entire MgO-SiO2 range? If so, can we use these values to create a phase diagram for these minerals?
What minerals are present in this composition range?
2. What are the main conclusions of the paper? Look in the Abstract and Conclusions.
The main conclusions of the paper are that the most accurate part of the MgO-SiO2 range to calculate equilibrium is the middle compositions. This is because they are thinner than the silicon end and do not need as high temperatures to reach equilibrium as the Mg end. The Si-rich end composition is less accurate because it is too thick to measure accurately. On the Mg rich end the temperatures …show more content…
The previous data that they used in this experiment does not give a consistent melting temperature but gives a range (between 2,800°C and 2,500°C) which shows that the melting temperature is too big to be accurate with. Another piece of evidence is the fact that only the middle compositions are completely plotted on the phase diagram for this system. Another piece of evidence that supports the conclusion is the fact that Forsterite (1890° C) and Enstatite (1577°C) had lower melting points than Magnesia. Forsterite also had a higher melting point than Cristobalite (1625°C). The phase diagram shows the highest recordable point in the middle composition range (middle of phase diagram) and not on the phase diagram ends. This is again supporting the conclusion that the most accurate part of this system is the middle compositions. Also, the fact that the liquidus was harder to create on the silicon end of the phase diagram helps support the conclusion that the middle compositions are the most reliable and accurate. All the above support the conclusion that the middle part of the diagram is the most accurate part of the system to calculate the equilibrium

are found, they are then compared to normative data to obtain the SNR loss. List pairs 1-8 have ten sentences in each list, with one sentence at each SNR of +21, +18, +15, +12, +9, +6, +3, 0, -3, and -6 dB. List pairs 9-18 have eight sentences in each list, with one sentence at each SNR of: +21, +18, +15, +12, +9, +6, +3, and 0 dB. Scoring…

It causes the bext axon to open up its gates 5. What is the role of the voltage-gated sodium channels for producing an action potential? The gated channels allow the sodium into the axon which causes the membrane potential above the threshold 6. What is the role of the voltage-gated potassium channels? Potassium gates close after sodium gates close too 7. What would happen if the voltage gated sodium and potassium channels opened a. at the same…

three quarters did not like the outside preparation. The one quarter liked the outside preparation because they felt that the research gave them more background about the lab they were doing. They could spend the time researching online exactly what the experiment wanted us to do. The other three quarters of the group felt that the labs were too difficult, and that the descriptions on canvas didn't provide enough information to create a procedure. They would prefer to have a procedure given to them. New…

The balance of protons and neutrons in a nucleus determines whether it will be stable or unstable. If the nucleus has too many protons or too many neutrons this will upset the balance. The upset of the balance disrupts the strong nuclear forces and the nucleus becomes unstable. The graph below demonstrates the neutron to proton ratio: From the graph shown many stable nuclei have an equal number of protons to neutrons, these are elements in the lighter sections of the periodic table. The heavier…

block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling? 0.04(300) =0.5+0.04v 12=0.24v V=22.22m/s 6. Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass…
