Different Types of Metaphors

Different Types of Metaphors Metaphors arent merely the candy sprinkles on the doughnut of language, not just embellishments to the music of poetry and prose. Metaphors are ways of thinking- and also ways of shaping the thoughts of others. All people, every day, speak and write, and think in metaphors. In fact, its hard to imagine how people would get by without them. And because figurative comparisons lie at the heart of language and thought, they have been picked apart by scholars in a variety of disciplines. Types of Metaphors There are countless ways of looking at metaphors, thinking about them, and using them. There are countless ways of looking at metaphors, thinking about them, and using them. But in deference to the metaphorical blackbirds of Wallace Stevens (The blackbird whirled in the autumn winds./It was a small part of the pantomime), here are a few of them. Absolute: A metaphor in which one of the terms (the tenor) cant be readily distinguished from the other (the vehicle).Complex: A metaphor in which the literal meaning is expressed through more than one figurative term (a combination of primary metaphors).Conceptual: A metaphor in which one idea (or conceptual domain) is understood in terms of another.Conventional: A familiar comparison that doesnt call attention to itself as a figure of speech.Creative: An original comparison that calls attention to itself as a figure of speech.Dead: A figure of speech that has lost its force and imaginative effectiveness through frequent use.Extended: A comparison between two unlike things that continues throughout a series of sentences in a paragraph or lines in a poem.Mixed: A succession of incongruous or ludicrous comparisons.Primary: A basic intuitively understood metaphor such as knowing is seeing or time is motion that may be combined with other primary metaphors to produce complex metaphors. Root: An image, narrative, or fact that shapes an individuals perception of the world and interpretation of reality.Submerged: A type of metaphor in which one of the terms (either the vehicle or tenor) is implied rather than stated explicitly.Therapeutic: A metaphor used by a therapist to assist a client in the process of personal transformation.Visual: The representation of a person, place, thing, or idea by way of a visual image that suggests a particular association or point of similarity. Regardless of the types of metaphors you favor, keep in mind Aristotles observation 2,500 years ago in Rhetoric: Those words are most pleasant which give us new knowledge. Strange words have no meaning for us; common terms we know already. It is metaphor which gives us most of this pleasure.

Nuclear Power Plant Safety System Research Paper

Nuclear Power Plant Safety System - Research Paper Example It is for this reason that extreme safety measures are normally adopted in nuclear power plants. The safety measures are normally taken to prevent any leak of the radioactive materials into the environment as a result of accident, breakdown and/or waste (INSAG). This paper therefore, aims at discussing the safety systems present in nuclear power plants’ reactors. The heart of a nuclear power plant is a nuclear reactor. It is in the reactor that those nuclear reactions (nuclear fusion or fission reaction) that produce heat energy (heat energy used to heat steam) take place. Therefore, all nuclear radiations are produced in the reactors as either leaks or wastes. It is for this reason that extreme systems are incorporated in these nuclear reactors. The objectives of nuclear reactor safety systems include: The above objectives of nuclear reactor safety systems are usually accomplished by use of a variety of equipment and machinery. These different equipment and machinery usually perform different specific roles in relation to nuclear power plant (reactor) safety (Nuclear Energy Agency). The safety systems and equipment that are usually available in all nuclear power plants include but not limited to following. In case nuclear reaction in the reactors is needed to be stopped urgently (as in the case of an accident) safety injection system can be used to bring the reaction to a halt. This is usually done by injecting a fluid (liquid) directly into the core of the reactor that usually absorbs the neutrons (INSAG). Basically, for boiling water nuclear reactors, the injecting liquid is usually a boron based solution, for instance boric acid. The boric acid (or any other boron associated liquid) is injected so as to displace water that is in the reactor core.
