This paper presents an introduction to fiber optic cable and the fiber optic communication system. An important phase in the supply of this new technology is to transport the fiber optic cable to the vicinity of service. Cable pulling and cable blowing - laminar flow; piston type - are the two main methods of installing fiber optic cable. Both methods of installation have limiting factors that need to be evaluated in order to perform a successful installation. The limiting factors for laminar type cable blowing are further discussed in this paper. A method was proposed to determine the forces - …
Hydrologic And Temperature Regime Influence On Growth And Recruitment Of Fishes In An Upper Midwest Riverine Ecosystem, Brett Donald Nelson
Hydrologic And Temperature Regime Influence On Growth And Recruitment Of Fishes In An Upper Midwest Riverine Ecosystem, Brett Donald Nelson

The natural flow regime is often identified as the primary driver of ecological integrity in rivers. The Minnesota River basin is characterized by a row-crop agricultural landscape with an extensive network of drainage tiles and ditches to improve land productivity. Intensive surface and subsurface drainage alters flow regimes, increasing the magnitude and frequency of high flows. Changes in river hydrology lead to alterations in geomorphology, including increased bank erosion, channel widening, and downward incision that can lead to floodplain disconnection. Disruption of historical hydrology can alter energy flow and connection to specialized habitats subsequently affecting important aquatic communities and populations …

The United States Environmental Protection Agency (USEPA) has listed much of the Upper Mississippi River (UMR) basin as impaired waters due to excessive turbidity, sedimentation, and nutrient loading. Of particular importance are the associated environmental problems (e.g. eutrophication, habitat and wetland loss, loss of biodiversity, and changes in water quality) that have developed within Lake Pepin, a popular recreational riverine lake of the UMR. Three major drainages contribute to these issues and empty in to the UMR near Lake Pepin - the Minnesota River Basin (MRB), St. Croix River, and UMR. The MRB makes up approximately one-third of the drainage …
Zebra Mussel (Dreissena Polymorpha) Habitat Associations In Four West-Central Minnesota Lakes, April Rose Londo
Zebra Mussel (Dreissena Polymorpha) Habitat Associations In Four West-Central Minnesota Lakes, April Rose Londo
All Graduate Theses, Dissertations, and Other Capstone Projects
In 1989, zebra mussels (Dreissena polymorpha) were first documented in the land of ten thousand lakes in the Lake Superior Basin at Duluth. Zebra mussels are successful invaders because the species attaches to substrates with byssal threads, can adapt to a wide range of environmental conditions, and has a free-swimming veligers that are easily transported. Although invasive mollusks pose a range of economic and ecological threats to inland waters, our understanding of zebra mussels in Minnesota lakes remains limited. To gain additional information regarding zebra mussel ecology in lake systems, I conducted research in four west-central Minnesota lakes that were …
Gis Analysis Of Brownfield Sites In The City Of Minneapolis, Shreya Vaidya
Gis Analysis Of Brownfield Sites In The City Of Minneapolis, Shreya Vaidya
All Graduate Theses, Dissertations, and Other Capstone Projects
Brownfield sites have many negative ramifications on a local area which includes loss of economy, decline in land use value and potential hazard to human health and the environment. Despite the efforts on redeveloping brownfields, Minnesota Pollution Control Agency (MPCA) claims that over 10,000 known contaminated or potentially contaminated sites remain across Minnesota and thousands are likely to exist but have not been identified and recorded. The objectives of this study are to map the brownfield sites in Minneapolis based on the information provided by the regulatory sources and to categorize and analyze all the sites on the basis of …
