ABSTRACT Online Examination System forms the lifeline of the Educational Institutes to thefunctioning of the Examination. It is very essential for an Institute to handle theExaminations and their results. It is very useful for an Institute to test its student scontinuously for their mutual development. This system is helpful for conducting(M.C) Multiple Choice Examinations which can be conducted regularly as well as for surprise tests and provides immediate results saving the precious time of

SULTAN’S BATTERY -Arvind Adiga Summary: Arvind Adiga’s Sultan’s Battery is an intriguing little story. It’s about a man‚ Ratna belonging to that part of the society which feels the weight of class differences the heaviest. He sells fake cures for venereal diseases (STDs) because this is the only way he can raise money for dowries for his three daughters. Ratna uses the astrologer as matchmaker

Osmosis in Potato Tissue Experiment Background Information Osmosis can be defined as the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration. The semi-permeable membrane allows small particles through it but does not allow large particles such as sodium chloride. Osmosis will continue until a state of equilibrium is reached i.e. there is no area with a higher or lower concentration than another area

Abstract An analysis of Bill Clinton’s speech In September 2012 Bill Clinton held a Speech at the Democratic National Convention. The Democratic National Convention was held in Charlotte‚ North Carolina‚ by Bill Clinton‚ the 42nd president of the United States. Our main focus of the analysis was to look what type of language Bill clinton used in the speech‚ sum up the main points of the speech like the message and time and context in connection to what is said in the speech and include the tools

3%‚ was diluted using 10 mL of hydrogen peroxide and 20 mL of water. In the second beaker‚ a ¼ dilution of potato extract was made using 2 mL of potato extract and 6 mL of water. The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase for exactly 5 seconds. It was next dried on a paper towel for 5 seconds‚ and finally placed at the

area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only be seen with a microscope‚ so you are going to use sticks of potato tissue in solutions that have different concentrations of dissolved substances to observe the effects of osmosis on living tissue. There are three basic relative concentrations of solutions. An isotonic solution has a concentration of dissolved particles

Abstract The overall objective of this lab was to a digital oscilloscope to measure various signals. The goal of Part 1 was to measure the mean value‚ the frequency‚ peak to peak voltage‚ and the RMS voltage of a triangular input signal. To meet this goal‚ a function generator was used to generate a 1 kHz triangular wave signal with a 1 V amplitude‚ and the oscilloscope was used to measure the values of that signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage

American Dream by David Kamp and the short story Thank You M’am by Langston Hughes. These three pieces of writing all had the common theme of tackling with expectation versus reality and the way our perceptions of ourselves and others can fail us. Abstract: I was intrigued by the combination of this week’s readings. I could appreciate each one for the individual themes and notions they raised‚ but only until reading Thank You M’am by Langston Hughes could I string the three together cohesively and

Straight blades produce regular chips while rippled blades produce ridged potato chips. * 5 The slices fall into a second cold-water wash that removes the starch released when the potatoes are cut. Some manufacturers‚ who market their chips as natural‚ do not wash the starch off the potatoes. Color treatment * 6 If the potatoes need to be chemically treated to enhance their color‚ it is done at this stage. The potato slices are immersed in a solution that has been adjusted for pH‚ hardness
