Trading Mechanism in National Stock Exchange 1. Introduction 1.1 Meaning of Trading Mechanism The trading mechanism in the stock exchange is based on a transaction between a buyer‚ seller‚ and a trading specialist who actually executes transactions in a stock exchange.

Active and passive transport are biological processes that move oxygen‚ water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand‚ passive trasport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.

Transport for London (TfL) aims to keep London moving and to continuously improve the standard of living in the city. The constant growth in population however is making this aim increasingly challenging. It is crucial for Transport for London to continue to improve their service if the city’s success is to continue. (Transport for London‚ 2015) In 2014 TfL identified their main priorities for the foreseeable future‚ safety and reliability‚ maximising capacity from the existing network and meeting
