AQUA SILENCER SYNOPSIS Diesel power invitably finds a very important role in the development of the plant’s economy and technical growth. Inspite of their high thermal efficiency‚ one cannot ignore the fact about the effect of their exhaust‚ in the atmosphere. It is a well-known fact that the toxic gases emitted in diesel engines are less than the engines. Due to high cost of petrol‚ diesel engines are more in use. Anticipating the use of diesel engines‚ even more in the near future; this system

In a dry round bottom flask‚ 1.5mL of cyclohexanone was added with 5mL of methanol. The solution was cooled in an ice bath for 3 minutes after which 0.2g of sodium borohydride was measured and added to the solution. Upon mixing‚ a gas was formed (bubbles). The round bottom flask was removed from the ice bath and placed at room temperature. After 10 minutes at room temperature‚ 5.0mL of 3M NaOH and 2.0mL of distilled water was added to the solution. Isolation and Characterization The solution was

Then in order to separate the DNA from the proteins and lipids one must use a filter paper with an appropriate pore size so that the flow rate of the solution is effective. Once the flow rate is minimal‚ the excess in the filter‚ consisting of cell debris and banana residue‚ can be disposed and then the filtrate is focused upon. With the specific amount of

Create a filter by placing the center of the cheesecloth over the mouth of the standing test tube‚ pushing it into the tube about two inches‚ and securing the cheesecloth with a rubber band around the top of the test tube. Cut a hole in the corner of the bag and filter your extraction by pouring it into the cheesecloth. You will need to keep the filtered solution which passes through the
