- a small downward deflection in the arterial pulse or pressure contour immediately following the closure of the semilunar valves, sometimes used as a marker for the end of systole or the ejection period. Called also dicrotic notch.

Shock waves, the sonic boom and the sound barrier Shock waves, the sonic boom and the sound barrier. This page supports the multimedia chapter The Doppler Effect in the volume Waves and Sound. It gives background information and further details. This page has details about the shock waves caused by a source travelling faster than the wave speed, Mach numbers, the sonic boom, and cloud nucleation.

Sandy Beach Processes This sand movement is caused by the waves that constantly break along coasts. Every wave shifts the sand and changes in the size of the waves and the direction of the waves increases or decreases the intensity of this sand movement.

tidal wave dicrotic wave the second portion of the tracing of a sphygmograph of the arterial pulse or arterial pressure after the dicrotic notch, attributed to the reflected impulse of closure of the aortic valves. Called also recoil wave.

Why does the ocean have waves? The gravitational pull of the sun and moon on the earth also causes waves. These waves are tides or, in other words, tidal waves. It is a common misconception that a tidal wave is also a tsunami. The cause of tsunamis are not related to tide information at all but can occur in any tidal state.

- When two waves arrive at a point in phase their peaks and troughs align, this causes constructive interference. The amplitude of the two waves will add up at this point, the … refore creating a brighter light or a louder sound, for example.alse. Constructive interference is when a larger wave is produced from two waves. If the amplitude were smaller or nonexistent, then that is called destructive interference.

What causes the dicrotic notch? Best Answer: Sudden closure of the aortic valve, causes a momentary elevated rebound in the pressure reading, such that the smooth downward slope of the pressure waveform is interrupted by a very brief upward movement; forming a sawtooth notch.est Answer: Sudden closure of the aortic valve, causes a momentary elevated rebound in the pressure reading, such that the smooth downward slope of the pressure waveform is interrupted by a very brief upward movement; forming a sawtooth notch.

- Standing Waves A standing wave is produced when a wave that is traveling is reflected back upon itself. There are two main parts to a standing wave: Antinodes – Areas of MAXIMUM AMPLITUDE Nodes – Areas of ZERO AMPLITUDE. Sound Waves Sound Waves are a common type of standing wave as they are caused by RESONANCE. Resonance – when a FORCED vibration matches an object’s natural frequency thus producing vibration, sound, or even damage.

- Accessibility links. What Causes a Tsunami? What Causes a Tsunami? A tsunami is a series of large waves generated by an abrupt movement on the ocean floor that can result from an earthquake, an underwater landslide, a volcanic eruption or - very rarely - a large meteorite strike. However, powerful undersea earthquakes are responsible for most tsunamis.

Dystonia In addition, there are forms of dystonia that may have a genetic cause: 1  DYT1 dystonia is a rare form of dominantly inherited generalized dystonia that can be caused by a mutation in the DYT1 gene. 2  Dopa-responsive dystonia (DRD), also known as Segawa’s disease, is another form of dystonia that can have a genetic cause. DYT1 dystonia is a rare form of dominantly inherited generalized dystonia that can be caused by a mutation in the DYT1 gene. 2  This form of dystonia typically begins in childhood, affects the limbs first, and progresses, often causing significant disability.

Science Tsunamis are caused by violent seafloor movement associated with earthquakes, landslides, lava entering the sea, seamount collapse, or meteorite impact. The most common cause is earthquakes. See the percentages on the right for the geological events that cause tsunamis.Note that 72% of tsunamis are generated by earthquakes. A disturbance that displaces a large water mass from its equilibrium position can cause a tsunami.ee the percentages on the right for the geological events that cause tsunamis.

SPONTANEOUS NYSTAGMUS Vestibular imbalance nystagmus (jerk type) Spontaneous nystagmus denotes movement of the eyes without a cognitive, visual or vestibular stimulus. Most commonly spontaneous nystagmus is caused by a vestibular imbalance. Normally, both vestibular nerves fire at a tonic rate.

- It is thought that most cases of primary dystonia are caused by problems with a part of the brain known as the basal ganglia. This is a collection of brain cells that are responsible for sending messages from the brain to various muscles in order to move them.ervical dystonia causes the muscles in the neck to spasm or contract meaning that the head and neck twist, are pulled forward, pulled backward or pulled from side to side.

Overview Causes include: 1  Surgery. Removal of or injury to lymph nodes and lymph vessels may result in lymphedema. 2  Radiation treatment for cancer. Radiation can cause scarring and inflammation of your lymph nodes or lymph vessels. 3  Cancer. If cancer cells block lymphatic vessels, lymphedema may result.  Infection.

- A Tsunami is a series of huge waves that strike a coast. The waves are caused when massive amounts of water are displaced due to an undersea disturbance. Earthquakes, Volcanic Eruptions, Meteorites or even nuclear weapons testing can cause them.

Dacryocystitis-sis-ËtÄ«t-És Dacryocystitis is infection of the tear (lacrimal) sac. The tear sac is a small chamber into which tears drain. The usual cause of dacryocystitis is a blockage of the nasolacrimal duct, which leads from the tear sac into the nose. Dacryocystitis may occur suddenly (acute) or be longstanding (chronic). In acute infection, the area around the tear sac is painful, red, and swollen.

- Piriformis syndrome is most often caused by macrotrauma to the buttocks, leading to inflammation of soft tissue, muscle spasm, or both, with resulting nerve compression. Microtrauma may result from overuse of the piriformis muscle, such as in long-distance walking or running or by direct compression.ome symptoms of piriformis syndrome occur as a result of local inflammation and congestion caused by the muscular compression of small nerves and vessels—including the pudendal nerve and blood vessels, which exit at the medial inferior border of the piriformis muscle.
