Procedure: Day 1: Buffer preparation First‚ the buffer was prepared by using the formula as follows: Figure 1: Calculation for prepare 0.5 M Tris buffer at pH 6.8 3.033 g of Tris was weighed and placed in 400 mL beaker. Then‚ 25 mL of distilled water was added into the beaker that contained Tris. The mixture was dissolved using the stirring rod‚ and then the magnetic stirring bar was placed in the beaker for further dissolve when measuring the pH. The pH meter was used to measure the solution

Abstract: The project is done to find out the impact of stock split on the stock market. In our project‚ we have made use of event study methodology to assess the accuracy of stock price reaction of 39 public listed Indian companies in National Stock Exchange (BSE) in the year 2006 and onwards. The abnormal returns (actual returns-returns from regression line) results were taken for 20 days before and after the announcement date to test whether the result is significant or not (Level of significance=5%)

In computer science‚ a buffer is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another. Typically‚ the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers). However‚ a buffer may be used when moving data between processeswithin a computer. This is comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory
