In class we discussed four different methods of peptide fragmentation that can be used for MS/MS-based sequencing. What are the four different methods and what types of ions do each usually produce?
1. Tandem mass spectrometry: A technique in an instrumental analysis where two or more mass spectrometers are coupled together using an additional reaction step to increase their abilities to analyze chemical samples. A common use of tandem-MS is the analysis of biomolecules, such as proteins and peptides.
2. MALDI-MS: Matrix-Assisted Laser Desorption/Ionization is an ionization technique that uses a laser energy absorbing matrix to create ions from large molecules with minimal fragmentation.
3. HR-MS: High-Resolution Mass-Spectrometry features both high resolution and high mass accuracy and is a powerful tool for the analysis and quantitation of compounds, determination of elemental compositions, and identification of unknowns.
4. GPC: Gel Permeation Chromatography is a type of size exclusion chromatography (SEC), that separates analytes on the basis of size. The technique is often used for the analysis of polymers.

2. In class, we discussed several ways that firms can secure financing for their strategies. Discuss the EBIT/EPS model. What are the advantages and disadvantages of each of the methods of securing funds?
Consider the four page replacement algorithms we have discussed in class: FIFO, OPR. LRU, and MFU. Among these, some are subject to ambiguity. That is, if you and another person tried to simulate the algorithm, and followed the idea correctly, you might end up with a different result (meaning pages loaded). For each of the four, indicate which have this problem, and which won't. Justify each
4. We have discussed in class that a monopolist can maximize its profit by charging different prices from two (or more) different groups of consumers. If you were a monopolist and could charge different prices for your product in domestic and foreign markets, how would you set your prices? Which market would receive a larger quantity of your product? Explain carefully how you would make this decision. Make sure to discuss the rationale behind it.
2. Consider a circular array based Queue as we have discussed in the lectures (class definition given below for reference) public class CircArrayQueue<E> implements Queue<E private EI Q private int front-0 indicates front of queue l indicates position after end of queue private int end-0: public CircArrayQueue( public int getSize (.. public boolean isEmpty ( public void enqueue (E e)... public E dequeue ) throws EmptyQueueException... Il constructor We are interested in implementing a Stack class based on the above...
can someone help explain this for me? In the class we discussed the class Account, suppose we have a constructor accepting one number as the parameter to indicate the initial balance for the Account object. What does the computer do when it executes the following statements? What are the differences between the two statements? Try to give as complete an answer as possible. Account[] accl= new Account[30]; Account acc2-new Account (30);
1-List the three types of Java methods discussed during lecture. Explain how each method type is used. 2- Describe the two contexts of a Java-class as discussed during lecture. 3- What is the purpose of the Java "new" keyword?
Answer both required questions: During this class, we discussed threats different marine mammal species face in the world today, as well as how their life histories may make it easier or harder for them to survive these threats. Rank the order in which each of the following four marine mammal species or populations is at risk of extinction (starting with 1 – highest risk and ending with 4 – lowest risk) and provide justification for what makes each group more...
5. Describe three different methods that can be used to get a buffer solution to a particular pH (specifically consider how an acid/base/concentration of ions can be used to calculate the pH). А. В. С. AL Ci
We discussed in class how ligands can affect the A. energy splitting. a. Categorize these complexes by whether their ligands are mainly i acceptors, i donors, or o donors. [Cr(CN)6]4-, [Fe(H20)6]2+, [CO(NH3)6]2+, [Cu(H20).]2+ b. Draw the tag-eg splitting and show the electron count for each complex from part a. Categorize each as high or low spin or write neither if both electron filling methods give the same result. Assume all o and i donors given here are weak-field ligands.
4. In class, we used both graphical and table methods to develop the idea that we can take a series of secant lines (lines that pass through two points of a function) and use them to approximate a tangent line. While the secant lines give us an approximate change, the tangent line gives us an instantaneous rate of change or the slopel/steepness of a graph at a single point. Do you this method always works? Does every point on every...
