The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start

The Giving Tree : Deep Meaning Do you want something so so bad like a video game or new clothes? Even if you think you haven’t‚ you probably have. We always want the new thing as soon as it comes out. Sometimes our parents will say no and most will think they have terrible parents and they will feel like they never get what they want. Before you ask yourself what you don’t have ask yourself what you do have.In The Giving Tree‚ Shel Silverstein uses the character of the tree to represent one’s parents

transmission systems Pulse Modulation Pulse Modulation consists essentially of sampling analog information signals and then converting those samples into discrete pulses and transporting the pulses from a source to a destination over a physical transmission medium. Pulse Modulation is a method of modulation that represents information as a train of pulses‚ wherein one or more characteristics of each pulse change with the input signal’s variation. Methods of Pulse Modulation • Pulse Width Modulation

History of Pulse Oximetry Before the Pulse-Oximeter the only way to measure SpO2 was by using a painful arterial blood gas which took a minimum of 20-30 minutes to view the result. In 1974 Takuo Aoyagi a Niigata University student disclosed his first Pulse-Oximeter for the use of pilots in World War 2. He set about searching for a non-invasive way of monitoring arterial blood oxygen saturation. Nellcor’s pulse oximeter was put on the market in 1983 and this used his theory developed in 1974. By

Pulse Polio Pulse Polio is an immunization campaign established by the government of India in 1995-96 to eradicate poliomyelitis (polio) in India by vaccinating all children under the age of five years against polio virus. This project deals with the ways to fight poliomyelitis through a large scale immunization programme‚ co-operating with various international institutions‚ state governments and Non Governmental Organizations. In India‚ vaccination against Polio started in 1978 with Expanded

detected by a photo diode sensor. The changing blood volume with heartbeat results in a train of pulses at the output of the photo diode‚ the magnitude of which is too small to be detected directly by a microcontroller. Therefore‚ a two-stage high gain‚ active low pass filter is designed using two Operational Amplifiers (OpAmps) to filter and amplify the signal to appropriate voltage level so that the pulses can be counted by a microcontroller. The heart rate is displayed on a 3 digit seven segment display

Morning Walk The proverb “Early to bed and early to rise” is well- Known and oft-repeated. It also reflects the wisdom and experience of life embodied in it. But only a few are there who are lucky to act according to this gem of a saying. Unfortunately‚ I am a late riser because I go to sleep quite late.
