through the cell membrane easily while sodium ions (Na+) have a more difficult time crossing. When a stimulus reaches a resting potential of a neuron it causes gated ion channels to open allowing the sodium ions (Na+) that was on the outside of the membrane to go into the cell. Sodium has a positive charge‚ which makes the neuron become more positive and depolarized. As depolarization reaches threshold of -55mV‚ the action potential is triggered and sodium ions (Na+) rush into the cell. If the neuron

NEW ECONOMY TRANSPORT Principles of Corporate Finance 7th Edition Richard A. Brealey and Stewart C. Myers This is an equipment replacement decision. The objective is to minimize the present value of future costs. But there are a few real-life complications. • Some cash flows are stated in real terms‚ some in nominal terms. We will use a real discount rate for the real cash flows‚ a nominal rate for the nominal flows. The alternative is to convert all cash flows to real

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

Rushing attacks send duplicate Route Request (RREQ) to the neighbor node. If Request RREQ is from the true source address‚ then the system is regular and begins to transmit data packets otherwise repeat the process. This process is illustrated in Fig 1. Check threshold value: Next check the packet delivery ratio‚ if packet delivery ratio drops to threshold then move to next step. The threshold value is calculated using dynamic threshold algorithm indicated in [3]. The source node randomly chooses

1. Triple DES Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm‚ which hackers eventually learned to defeat with relative ease. At one time‚ Triple DES was the recommended standard and the most widely used symmetric algorithm in the industry. Triple DES uses three individual keys with 56 bits each. The total key length adds up to 168 bits‚ but experts would argue that 112-bits in key strength is more like it. Despite slowly being phased out‚ Triple DES still
