Measurement of hardness is a useful non-destructive testing method used to determine the applicability of the crystal in the device fabrication. Microhardness study was carried out on 2PPA single crystal using a Vickers microhardness tester fitted with a Vickers diamond pyramidal indenter in order to evaluate its mechanical stability. The static indentations were made at room temperature and 323 K with a constant indentation time of 5 s for all indentations. As grown polished sample of 2PPA was used

Emergence of Liquid Fund as a Prominent Option for Treasury Management Executive Summary All organisations maintain current accounts in banks to ensure prompt deposit and withdrawal of money‚ while the money in the current account does not fetch any return. With increase in competition and squeezing of profit margins‚ measures were required to utilize the money lying idle in the current account without hampering the prompt flow of money. Liquid funds provide the solution for utilization of

In this experiment I conducted a test to see if solid crystals would form better between sugar and unionized salts. Also under two different temperatures‚ would this effect the size at all. My overall hypothesis was to test at what rate and size would crystals grow in sugar vs salt at different temperatures‚ and that I thought the salt would produce a greater amount of crystal deposits. My method was hanging a string from a pencil immersed in the different solutions. My results were similar in both

Abstract The history of the head-up display dates back to World War II. Since then‚ the head-up display has gone through a variety of changes and upgrades. Both the Airline Pilots Association and the Airline industry pursued the development of the head-up display because of the advantages it offers. As with any new technology‚ the head-up display has advantages and shortfalls. Education however‚ is the key to fully understanding new technology including the head-up display.

How to maintenance of liquid assets to ensure frm has adequate cash? Asking the above-referenced question without statistics makes it impossible for anyone to give you a proper answer. Generally speaking‚ you must limit expenses and ensure that some of your assets are in the form of short term assets. The higher your short term assets and the less your short term debt‚ the better your ability to pay the debt (short term liquidity ratio / liquidity ratio help you determine this). There is no

Discuss one or more evolutionary explanations of group display in humans. (25 marks) Group display in humans has been studied by a variety of psychologists both classic and contemporary. Psychologists such as Le Bon believe that crowd behaviour is explained through the individual taking on the ‘psychology’ of the crowd’. Essentially‚ the actions of a crowd can be explained through situational factors‚ such as convergence in one location‚ or the result of normless situations where people look to

Throughout the centuries‚ people have often wished they could somehow know what would happen in the future before it actually happened. Sometimes‚ however‚ certain consequences are hinted at ahead of time‚ giving you a chance to take care of it before it is too late. In his book 1984‚ George Orwell uses foreshadowing through Winston ’s dreams and memories to predict what will happen in later events‚ which then explain what took place before. (S) One memory that was foreshadowed was the last time
