I will be discussing the legal environment of my career choices, taxing authorities, entity structure, graduate school in order to obtain certain license, self-assessment of my chosen careers. First, I will discuss how I can work as a corporate financial analysis in investment banking. After that, I will talk about what I need prepare to be an actuary. 1.corporate financial planning and analysis The responsibility of a corporate financial planing and analysis is to support management planning and decision making by identifying, maintaining, and evaluating information,as well as recommending actions. * Legal environment * Entity structure Investment banking is concerned with the primary function of assisting the capital market in its function of capital market intermediation, i.e. the movement of financial resources from those who have them means investors, to those who need to make use of them means issuer for generating profit. Therefore, it can be inferred that investment banks are those institutions that are the counterparts of banks in the capital market in the function of intermediation in resources allocation. Investment banks carried on carious activities it helps companies and governments and their agencies to raise money by issuing and selling securities in the primary market.

Everything covered in lecture is fair game for the exam. You will be provided with a periodic table, solubility rules, conversion factors and constants (similar to those at the back of the chapter.) The exam will contain a mixture of multiple choice questions similar to those assigned as homework and at the end of each chapter in the textbook. (The Practice Examples are within the chapter, the problems appear at the end of the chapter.) Students must have their Temple photo ID card during lecture exams. TU-ID Numbers must be correctly and completely filled in on exams to ensure your score is properly recorded. Students are not allowed to have cell phones and other PDA devices on their persons while taking an exam. Cell phones/PDAs are to be placed in bags/backpacks which will be kept at the back of the lecture hall. Students may leave cell phones/PDAs on the front bench of the lecture hall. Students who are caught using cell phones/PDAs during an exam will be ejected from the exam and will receive a score of zero. This violation will be reported to the Dean and the Vice-Provost who will then take the appropriate disciplinary action. Only pens/pencils and scientific calculators (non-programmable and non-graphing) are allowed to be with students during exams. Students are not...

So the emphasis of this unit is the biological significance of chemical molecules. As part of the course, there are six biological molecules that you need to know about: CH2OH Carbohydrates O H H OH OH These molecules are one of many vital to life. They are used for energy (for both storing and supplying energy), and in some cases can be used structurally, such as cellulose Lipids H O H H C H H C H H C O C O O C O O These come in many varieties: fats, oils, cholesterol, steroids, and more, and have uses in cellular membranes, insulating and protecting, and also act as a minor energy supply C H Proteins Proteins have several uses, such as for transport and structure; but they are also the basic components of all enzymes, hormones, antibodies, haemoglobin, ribosomes, and many more materials Water H O H Another essential life component, this is the most important content of many reactions forming most of these molecules, and also metabolic reactions; water is also an essential structural component in plants, and in the diet of animals Nucleic acids These are responsible for the formation of both DNA and all forms of RNA molecules, consisting of individual nucleotides www.asbiology101.wordpress.com Enzymes ...

Organic chemistry is a course in which one idea almost always builds on another that has gone before. 2. Study materials in small units, and be sure that you understand each new section before you go on to the next. Because of the cumulative nature of organic chemistry, your studying will be much more effective if you take each new idea as it comes and try to understand it completely before you move onto the nest concept. 3. Work all of the in-chapter and assigned problems. 4. Write when you study. over and over again. Write the reactions, mechanisms...

...CHEMICAL EQUILIBRIUM Equilibrium occurs when the rate of the forward reaction is equal to the rate of reverse reaction. Concentration of the reactants and the products remain the same. Dynamic equilibrium occurs when the processes do not stop and forward and reverse reactions still continue in both directions at the same rate. A homogeneous reaction is a reaction wherein all the reactants and products are in the same phase e.g. all are gases. A heterogeneous reaction is a reaction wherein all the reactants and products are not in the same phase. If there is no interaction between the system and its surroundings, i.e., a system from which no substances in the reaction can escape, we say it is a closed system. Calculation of the substance amount and concentration at equilibrium We can determine the concentration of the substance by dividing the number of mol of the substance at that stage of the reaction by the volume of the container in dm3, i.e.: c= n/V where c or [ ] = concentration of the substance in mol.dm-3 n = number of mol of the substance V = volume of the container in dm3 It is handy to use a table to determine these values. Example 1 A mixture of 5 mol H2(g) and 6 mol I2(g) are placed in a sealed container of 2 dm3 at a temperature of 4580C. The balanced chemical equation for the reaction is: Equilibrium is reached after a certain time. At equilibrium there is 4mol HI(g) in the container. Calculate the concentrations...
