categories: acute and chronic.[1][2][3][4] Acute bronchitis is characterized by the development of a cough or small sensation in the back of the throat‚ with or without the production of sputum(mucus that is expectorated‚ or "coughed up"‚ from the respiratory tract). Acute bronchitis often occurs during the course of an acute viral illness such as the common cold or influenza. Viruses cause about 90% of acute bronchitis cases‚ whereas bacteria account for about 10%.[5][6] Chronic bronchitis‚ a type

Quantum Mechanics ~Three physicists were instrumental: Heisenberg‚ De Broglie‚ and Schrodinger ~Their approach stemmed from De Broglie’s matter wave concept known as "Wave Mechanics" or "Quantum Mechanics" ~ Bohr’s model was inefficient for atoms other than hydrogen or poly-electronic atoms ~ This new approach to a model of the atom focused on the concept of wave functions ~ Since electrons are particles and therefore have wave properties ~ Schrodinger viewed the electron as a standing wave

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

Books and Resources • Tom Kibble and Frank Berkshire‚ “Classical Mechanics” • Douglas Gregory‚ “Classical Mechanics” Both of these books are well written and do an excellent job of explaining the fundamentals of classical mechanics. If you’re struggling to understand some of the basic concepts‚ these are both good places to turn. • S.

Celestial Mechanics Orbital Maneuvers Earth‚ Moon‚ Mars‚ and Beyond Rodolfo G. Ngilangil Jr. MBA‚ BSAE Impulsive Maneuvers Impulsive maneuvers are those in which brief firings of onboard rocket motors change the magnitude and direction of the velocity vector instantaneously. The position of the spacecraft is considered to be fixed during the maneuvers. This is true for high-thrust rockets with burn times short compared with the coasting of the spacecraft.

Sports Mechanics Of Tennis The hitting and subsequent motion of a tennis ball in playing a forehand topspin Abstract The forehand topspin is one of the primary techniques that is utilised in modern day tennis. It has been used to enhance a player’s overall forehand skills that result in the maximising of a players groundstroke power output. This report will analyse the motions the tennis player and tennis ball undergo‚ the forces acting on the player and the ball and lastly‚ the force transformation

writing 5 stories in one‚ because the writer leaves gaps in the story that the reader will subconsciously fill in. Because of that the story will be very different from one reader’s perspective to the next. In Raymond Carver’s short story "Popular Mechanics‚" there is no clear ending. He also makes the story pretty vague by leaving out quotation marks‚ not telling the reader who is saying what‚ giving no background‚ and only allowing each character to say a few words at a time. The story as whole leads

Title: Bone Mechanics Objectives:- -To become familiar with LabView software and National Instruments‚ in order to record and observe the strain signals from chicken bone and an aluminum rod. Background: Data acquisition is the use of computer software connected to a measuring device. Signals and measurements are recorded‚ which is converted into a digital signal only understood by a computer. Data is recorded at a certain speed that is processed in real time‚ and can be immediately interpreted
