The main objective of this thesis is to investigate the microprocessor's
potentials to improve the productivity of Industrial
Engineers engaged in work design and measurement. More exactly, the
following four hypotheses were proposed and investigated:
(1) A Universal Time Data (UTD) structure could be used to
accommodate a variety of...
Coastlines have traditionally been engineered to maintain structural stability and to protect property from storm-related damage, but their ability to endure will be challenged over the next century. The use of vegetation to reduce erosion on ocean-facing mainland and barrier island shorelines – including the sand dunes and beaches on...
Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...
This thesis presents a discussion of the main materialistic theories proposed to explain the process of development among the indigenous population of Latin America. Four theoretical approaches are presented and discussed. The first one deals with the social group referred to as peasants. The second one explains the process of...
Gravity and seismic data obtained by the geophysical group at
Oregon State University on the R/V YAQUINA during 1969, 1971, and
1973 plus other available data over the area just west of Nicaragua
and Costa Rica indicate the tectonic complexity of the region. Gravity
measurements show negative free-air anomalies over...
Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleterious effects for calcifiers, but responses vary greatly across taxa and can be influenced by variations in other environmental characteristics. Scaling...
