Identity is in Flux Because of Environment

- 1) Identity refers to how one conceptualizes oneself in some form of social context, and is usually considered as a personal attribute in sociological and psychological research. However, one’s identity of self is dynamically mediated by their environment and is constantly in flux. Who someone is and who they want to become are affected by the availability of resources and opportunity in their environment, the expectations of others, and the social, cultural, and historical contexts in which they seek to identify themselves (Holland et al....   [tags: social, science, academics]

Heraclitus - Permanent Flux

- Permanent Flux It is said that every great journey begins with one step. This is not true. A more accurate saying would be, “every great journey begins with the idea of the journey”, thus leading to the idea of the step, and so on. The steps will surly follow an idea, but nevertheless the ideas will always precede any action. Once one gets an idea in one’s head, one must either forget it, or act on it. Such as the case with the first Philosophers, known now as the Pre-Socratics.

- ... This is termed intraspecific competition. These effects can be extended to include pairwise interactions between species (e.g. competition, mutualism, predator-prey), which is termed interspecific competition. To illustrate this concept and how it relates to resource limitations, the concept of predator-prey interactions will be discussed briefly.

What Factors Control Carbon Mineralization and Flux in Bog Soils and How Would These Soils Respond to Global Climate Change?

- I. Introduction: What is a Bog. The word "bog," from the old Gaelic "bogach," is commonly used to refer to any stretch of waterlogged, swampy ground. The words, fen, moor, muskeg, peatland, and mire are also used to describe these areas, which can lead to some confusion over terminology. Specifically, a bog is "a peat accumulating wetland that has no significant inflows or outflows and supports acidophilic mosses, particularly sphagnum" (Gosselink and Mitsch 1993). The vast majority of bogs are located in the moist, cool boreal regions of North America and Eurasia....   [tags: Climate Bog Ecology Papers]

End-Winding Analysis in order to minimize the Circulating Current in a Large Synchronous Generator

- Abstract- This paper deals with the circulating current distribution calculation and its resultant ohmic losses in a large synchronous generator. Circulating currents are produced by the induced voltage differences between parallel strands in a bar that cause high ohmic losses in high power synchronous generators. In this paper, three different cases are assumed for the armature end winding structure, and a 3-D finite element model is adopted to calculate the effectiveness and resultant losses of these cases....   [tags: Research Analysis ]

This phenomenon is called superconductivity; correspondingly, materials which have this property would be called superconductors. Because of this great discovery, in 1913, he won a Nobel Prize in physics for his research in this area.

Maglev Trains And The Technology Behind Them

- Maglev Trains And The Technology Behind Them Introduction Magnets Magnetism is a phenomenon that occurs when a moving charge exerts a force on other moving charges. The magnetic force caused by these moving charges sets up a field which in turn exerts a force on other moving charges. This magnetic field is found to be perpendicular to the velocity of the current. The force of the field decays with distance from the charge.

The Things They Carried by Tim O'Bryan

- Truths are concepts that are not simply recognized, but that are to be discovered or created. One person's truth may be seen by another as a lie. What is the difference between an unnoticed myth and an unrecognized truth. The difference between the two lies within the eye of the beholder. For Tim O'Brien, the author and narrator of The Things They Carried, truth equals what the reader thinks happened and what really happened. Whether or not it actually happened does not matter; something can happen and not be true....   [tags: war, truth, stories]

Arthur Machen’s The Great God Pan

- In “The Great God Pan” (1894) Machen uses ancient Greek god Pan to serve as a symbol of spiritual reality that lies beyond human perception and knowledge. Machen’s use of this divine entity and his success in rediscovering a minor figure of the classical pantheon, yet “mostly neglected by earlier authors of English literature” (Pasi 69), provide what Gilles Deleuze and Felix Guattari argue to be the significant value of a minor author, “…by using a number of minority elements, by connecting, conjugating them, one invents a specific, unforeseen, autonomous becoming” (106)....   [tags: The Great God Pan Essays]

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electric charge is the property of matter that causes it to experience a force when close to other electrically charged matter. Conduction in metals must follow Ohm's Law, which states that the current is directly proportional to the electric field applied to the metal. The key variable in applying Ohm's Law is a metal's resistivity....   [tags: ohm , conductivity, resistivity]

The Magnetic Fields Of The Magnet

- Introduction: Magnetism was not studied or utilized before 1821 as it is today. A few hundred years ago people understood how magnets worked, but didn’t have many applications of the magnet because they were limited by the technology of their time. The applications of magnets today have opened a new door as to how we can harness the power of a magnet. I had a basic working knowledge of how magnets worked, such as polarity, but with researching different aspects of the magnet I have learned that we need to advance the potential capabilities of the magnet and fully understand how we can harness the magnet....   [tags: Magnetic field, Electromagnetism, Magnetism]

The Earth Magnetic Field

- It’s the magnetic field that extends from the earth’s interior to where it meets the solaria stream of charged particles emanating from the sun. The magnetic field resembles the field of a large bar magnet near its center or that due to a uniformly magnetized sphere. Its origin is thought to be generated deep down in the earth’s core. At the surface of the earth, the pole of this equivalent bar magnet, nearest the north geographical pole is actually a south” magnetic pole. This paradoxical situation exists since by convention a north seeking end of a compass needle is defined as pointing north yet must point to a pole of opposite sense or South Pole of the earth’s magnetic field....   [tags: solaria stream, magnetic storms]

Ratio of Charge to Mass for the Electron

- Ratio of Charge to Mass for the Electron Introduction: The object of this lab was to determine the measure of the ratio of an electron to its mass. This is done by accelerating a stream of electrons through a measured potential difference. The stream of electrons moves through a uniform magnetic field. It is perpendicular to the velocity of the electrons. The path of the electrons is circular because of this fact. The ratio of e/m can be found by the relationships between the measured accelerating potential difference, the diameter of the circular path described by the electron, and the magnetic flux density....   [tags: Papers]

Misconceptions about Human Behavior in To Kill a Mockingbird

- How do we define normal human behavior. In order to determine the answer we must first determine what behavior really is, the conclusion is easy enough to reach: Human behavior derives from reactions to internal or external stimuli (Salvador); these reactions bring about emotions that dictate a particular response or behavior. These become part of a person’s personality, which defines their behavior, due to this, a person’s behavior is able to adapt to the stimuli with their environment and thus the definition of “normal behavior” is in a state of constant flux....   [tags: To Kill a Mockingbird Essays]

However, it was not known what value the resistance would approach if the temperature was reduced towards 0K until Onnes, while experimenting with platinum, discovered that, its resistance fell when cooled to a very low value that depended on the metal’s purity. As the temperature of mercury was reduced toward 0K, the value of the resistance would fall smoothly until the resistance fell extremely suddenly at about 4K....   [tags: physics science superconductor]
