    The Applications Of Technology In The First Decade Of The Twenty-First Century


    Words: 3041    Pages: 11    Paragraphs: 39    Sentences: 161    Read Time: 11:03
                  A quote I heard many times when I was in high school and which I now know traces back to Sir Francis Bacon, one of our earliest scientist or philosophers as they were then called, is the statement "Knowledge Is Power." Today, I believe that the fuller, more correct statement is to say, "the application of knowledge is power."

                  The laser is a device that beams a ray of light that is both scientifically and practically of great use, because it is coherent light. The beam is produced by a process known as stimulated emission, and the word "laser" is an acronym for the phrase "light amplification by stimulated emission of radiation."
                 
                  Light is just like radio waves in the way that it can also carry information. The inform

    Scientific Management


    Words: 260    Pages: 1    Paragraphs: 6    Sentences: 14    Read Time: 00:56
                  The first systematic theory of organisation was formulated in the early years of the present century under the driving force of Frederick W. Taylor (1856-1915). An engineer by profession, he is regarded as the father of the scientific management.
                 
                  Taylor was stimulated in his early thinking by a number of predecessors, particularly the American industrialist and engineer Henery R. Towne.

                  Energy can be defined as the capacity to do work, whether that work be on a gross scale as raising mountains and moving air masses over continents, or on a small scale such as transmitting a nerve impulse from one cell to another. There are two kinds of energy, potential and kinetic. Potential energy is energy at rest. It is capable of and available for work.

                  Organisms can respond to environmental stress in such a way that their tolerance zones may change. The genetic changes that occur during the evolution of the species because of mutation and natural selection are called adaptations.
                 
                  Presumably, each species is fairly well adapted or fit, if it has been in its particular environ-ment for many generations. The range of tolerance of a species may b

    Overlapping Niches And Niche Separation

                  Though two popula-tions cannot coexist in a given habitat with precisely the same niche, it is highly probable that the niches of different populations will show varying degrees of overlap.
                 
                  This occurs when two organi-sms use the same resource, such as food. Thus the concept of the niche is clo-sely associated with the concept of competitive exclusion and competitive relationships among spices

                  The tundra presents the most common example of "fragile eco-system" (Clapham, Jr., 1973). Tundra which means "marshy plain", lies largely north of latitude 60?N (i.e., between the Arctic ocean Mid polar ice-caps and the forests to the south) and is characterized by the absence of trees, the presence of dwarfed plants, and an upper ground surface that is wet, spongy and uneven, or hummocky, as a re

                  As a lake fills with silt it changes gradually from a deep to a shallow lake or pond, then to a marsh, and beyond this, in some cases, to a dry-land forest. When a crop field is deserted or a forest is severely burned over, it is just like a plot of bare ground and a series of plant communities grow up there and replace one another- first annual weeds, then perennial weeds and grasses, then shrubs

    Predation : Components & Effects


    Words: 1120    Pages: 4    Paragraphs: 21    Sentences: 69    Read Time: 04:04
                  Predation is a form of disoperation, at least in point of im-mediate effects, since one animal kills another animal or plant for food Like parasitism, predation is important in community dyna-mics but both differ in the point that a predator tends to be large than its and it catches its prey from without, while a parasite is smaller than its host and consumes it from within.

                  Through mutation and introgression followed by selection, modification of gene frequencies (genetic drift) and recombination, many species populations come to be composed of a number of freely interbreeding biotypes or races, each adapted to a particular combination of parameters in the habitat.
                 
                  Such a species is called polytypic species. When the component populations of a polytypic species ar

Pinkerton (1955), Cooke (1967), Margalef (1968), Mc Cormick (1968), E.P. Odum (1969) and Whittaker (1970) to develop a model of succession that suggests the following widely applicable trend.
