A 5 page paper discussing the physical characteristics, geographical distribution, morphological adaptations and reproduction of the genus Cycas of the Cycadaceae family. The long survival of Cycas is easy to explain, though some species are now endangered because of their commercial value and the slow growth rate of their seedlings. Others are in danger because of loss ...

A 5 page discussion of bacterial growth in the presence of antibiotics. Examines how bacterial growth is dependent on a number of their physiological mechanisms such as enzymes, proteins, and even the communication of one organism with another in a phenomenon referred to as quorum sensing. Emphasizes that it is critical to continue ...

An 8 page paper discussing the research investigating possible paths to genetically altering this opportunistic bacterium so that it is unable to cause disease. The organism is ubiquitous, but rarely causes disease in healthy individuals. In those with compromised immune systems, however, it can be quite devastating. The focus of the research here is on genetically altering ...

This 6 page paper looks at the way in which global change is monitored by different types of remote sensing equipment, from weather balloons to Satellite equipment and the software used to evaluate the data. The bibliography cites 7 sources.

An 18 page paper discussing research in introducing natural gas as an enhancer for diesel fuel. Natural gas cannot fully substitute for any fuel in any type of internal combustion engine, but there have been attempts to use a pilot injection of diesel followed by injection of natural gas. The nature of natural gas is such that ...

A 5 page discussion of destiny as it relates to the actional and nonactional theories. Associates the theory of biological determinism with the nonactional theory but observes other areas of research which indicate numerous factors, particularly parental involvement in our childhood, affect the way we live our lives. Concludes that there is some ...

A 5 page discussion of the design and application of the infrared telescope. Discusses the recent acquisition of our ability to monitor infrared light and the information which can be obtained in so doing. Emphasizes that the infrared telescope, although only introduced in the last four decades, has evolved to be one of ...

An 8 page consideration of the theory of catastrophism in relation to the dinosaur extinction which occurred during the Cretaceous and Tertiary periods. Weighs the geologic evidence of such an event against the environmental effects which would have occurred to contend that such an event would have had much further effects than on the ...

5 pages in length. The Great Dying is historically known as a period of time two hundred and fifty-one million years ago where the earth suffered significant and overwhelming devastation. The most intriguing aspect about this mass extinction of plant and animal life is that scientists still have no concrete evidence why such ...

A 5 page discussion of the concepts of natural selection. Details Darwin's theories in regard to fitness and adaptation to an ecological niche. Emphasizes that much of Darwin's work is supported by a volume of contemporary scientific information. Concludes that while evolution is not a phenomena which can be precisely detailed, and ...

A 5 page paper discussing evolution, natural selection and social Darwinism. There are many who continue to argue today that Darwin was mistaken, that origin of species could not arise in the manner he described. There are many more, however, absolutely convinced that Darwin found the mechanism by which species arise. The controversy surrounding Darwin's theories ...

An 8 page discussion of the events which resulted in the extinction of the dinosaurs. Suggests that a meteoric impact with the earth set in motion a series of environmental events which ultimately translated into dinosaur extinction. Bibliography lists 10 sources.

A 5 page discussion of the factors which can influence our state of happiness. Contends that while some of these are obvious, such as the presence or absence of psychological conditions, and others are less obvious aspects such as sexual fulfillment.
