This thesis presents thermodynamic evaluations of various biomass-fueled combined-cycle power plants using a computer model developed for simulating such plants. The combined-cycle systems Investigated are characterized by having a wood-fueled combustor, an indirect-fired gas turbine, and a steam cycle. This work was part of a larger biomass energy project at...
The purpose of the study was to survey aspects of environmental
knowledge and beliefs among Grade 10 students in Australia, in the
belief that such information would be useful for workers in the developing
field of environmental education there.
A survey instrument prepared and used for a similar purpose in...
Transcriptomics and gene expression profiling enables the elucidation of the genetic response of an organism to various environmental cues. Transcriptomics enables the deciphering of differences between two closely related organisms to the same environment and in contrast, enables the elucidation of genetic responses of the same organism to different environmental...
Stephen Biko was a black leader in South Africa who
died in police custody on September 12, 1977. Biko's death
echoed within the Republic of South Africa and around the
world, showing that racial tensions in that country were
severe. At his death he was a hero to the black...
Considerable evidence exists to suggest the notion that selected
personality traits may be related to specific aspects of academic
achievement. This study was directed toward the investigation of this
relationship in the case of non-science majors enrolled in a college
course in physical science.
Personality was assessed with the California...
Acquisition of divergent-productive thinking skills by using
elementary science materials constitutes the basic idea of this experiment.
The data collected was used to determine statistically if
the materials had a significant role in inducing such skills.
The Ss were fifth-grade students obtained from two public elementary
schools in Oregon. Those...
The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is...
This research was conducted to compare the performance of
community college students to four -year institutional students both
of which were enrolled in one of three different programs of general
college chemistry for nonscience majors during the 1967 -68 academic
year. The three programs were defined as follows:
Program A...
