Vibration

In the short horror story “The Cask of Amontillado,” Edgar Allan Poe writes about a man who seeks revenge by murdering another man by luring him with alcohol. Then, he traps him in a cellar, leaving him to die. He creates suspense and a dark mood in this story by using many methods, but one that he did was to use first person to narrate the story. This is important because it adds another view of the story, creates a dark mood, and makes a more suspenseful scene. Edgar Allan Poe uses first…

In gloves industry, and for the maximum care of hands, Polyurethane-made gloves has shown the most remarkable effect than any other material. Known as one of the most versatile quality polymers, Polyurethane gloves are in huge demands at the consumer end. Well, what are the qualities that make a Polyurethane glove the best? To be honest, you can't find much stronger grip (and no sticky sensation) in a glove made by Polyurethane than any other material. The other qualities of this material are…

include variations in acoustic parameters of perturbation in vocal fold vibration such as reduced jitter and shimmer (Franca, 2006). Vocal jitter is defined as variation of the frequency (number of cycles or events per unit) of successive vocal folds cycles, whereas vocal shimmer is defined as short-term (cycle-to cycle) variability in vocal fold vibration amplitude (Titze, 1994). Jitter and shimmer are indicators of vocal fold vibration perturbation that draw a parallel with perceptual…

notice it and suspended objects may begin to swing (Rose 48). At an intensity of three, people indoors can feel the vibration, but may not recognize it as an earthquake and hanging objects begin to swing (Rose 48). Damages usually occur once the earthquake has reached a magnitude above four or five ("Earthquake Effects & Experiences"). When an earthquake has an intensity of four, the vibration is like a truck hitting a building; cars rock, dishes rattle, and wooden walls creak (Rose 48). At the…

This article looks at the seismonastic response (the response of a plant to touch or vibration) and how it utilizes the transport of K+ in the pulvinar cells (the thickening at the base of a leaflet that causes the movement of the leaflet based on differing turgor pressure in these cells). They tested many hypotheses regarding the seismonastic reaction in the Mimosa pudica, one of which tested whether there was an increased efflux of K+ from pulvinar cells during stimulation. The experimenters…

There are both similarities and differences between the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. One of the observed differences is that when the quartz is present at different temperatures. The α-FePO4 phase when present at low temperatures, tend towards the values obtained for β-FePO4 at high temperature. In addition, this case is true for all α quartz when at low temperature, in that it will tend to the values obtained for its respective β quartz experienced at…

any movement. After a while, the rocks break because of all the pressure that's built up.This happens when the rock underground breaks suddenly. When the stress finally builds up, it releases, sending seismic waves which are also known as vibrations. The vibrations are responsible for making the ground shake. When the rocks break, the earthquake occurs. Earthquakes are all normal geographical behaviors of the earth. Earthquakes produce three types of seismic waves: primary waves,…

Baseball has been America’s favorite pastime for nearly 150 years, and though the specifics of the game have evolved, the overarching physics allowing the ever-popular sport to achieve the exciting feel it boasts, has not. How well a baseball is hit depends on four factors: angle of contact, location of contact, bat speed, and pitch speed. By looking into the forces of physics that dictate this well-known sport, I hope to gain a better understanding of how and why hitting a baseball works and…

The idea of music playback came from Édouard-Léon Scott de Martinville, a bookseller, and trader from Paris. In 1857, Scott obtained a fascination for the human ear which led him to invent the Phonautograph, an instrument primarily used to study acoustics in laboratory research. The construction of the phonograph was heavily inspired by the anatomy of the human ear. Consisting of three main components that replicated the build of the ear canal, eardrum, and ossicles. Sound waves would be…

Title “ The kind of deep reading that a sequence of printed pages promotes is valuable not just for the knowledge we acquire from the author’s words but for the intellectual vibrations those words set off within our minds. In the quiet spaces opened up by the sustained, undistracted reading of a book…we make our own associations, draw our own references and analogies, foster our own ideas.” Nicholas Carr concludes his article “ Is Google Making Us Stupid? ” by stressing the significance in…
