Introduction: In current upsurge in economic condition globally brought on by competition and uncertainty‚ all organisations are impacted with need for changes to remain viable in performance of duties. This trend have prompt companies in adopting suitable approach which are unique to its operation and thus being effective in achieving goals objectives and prospect for development.

Checks and Balances‚ the constitutional controls whereby separate branches of government have limiting powers over each other so that no branch will become supreme. Perhaps the best-known system of checks and balances operates in the U.S. government under provisions of the federal Constitution. Most national‚ state‚ and local governments have at least the mechanics of a system of checks and balances. Even dictatorial governments‚ otherwise scorning restraints on powers‚ provide internal checks to

these branches‚ they also created a system. This system was called “checks and balances”. “Each branch has powers that it can use to check and balance the operations and power of the other two branches.” With this system‚ each of the three branches can limit the powers of the others. Congress created this system to help ensure that no branch became too powerful. Each branch has powers that can be used to “check and balance the operations and power of the other two branches.” For example‚ in the constitution

I.Cerebrospinal Fluid Cerebrospinal fluid is a clear‚ colorless liquid produced within spaces called ventricles in the brain. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and the spinal chord. It bathes the exposed surfaces of the central nervous system‚ and completely surrounds the brain and spinal cord. In addition‚ a space inside the spinal chord called the central canal also contains cerebrospinal fluid. CFS acts as a cushion for the neuraxis

Current Balance PHY 114 10/29/2013 Abstract: The purpose of this experiment was to understand the current balance‚ current balance is an apparatus that allows measurement of the small force between two current carrying conductors. It consists of two parallel horizontal bars‚ which are connected in series. The current flows in opposite directions in the two conductors so there is a repulsive force between them‚ by Newton’s third law there are equal and opposite forces on both wires. In the

7 (a) Explain the current and financial accounts in the balance of payments. Balance of Payment or also called as BOP is a statistical statement that systematically records of all economic transactions between one country and the rest of the world during a given period of time. For example‚ BOP shows the details of the total payments made by a country and also the total receipts by it. There are three major components that are summarized in the BOP which are Current account‚ Capital account and
