The Des Moines Rapids: A History Of Its Adverse Effects On Mississippi River Traffic And Its Use As A Source Of Water Power To 1860, Donald L. Enders

Theses and Dissertations

During the 19th Century, the Mississippi River was the chief commercial highway in the United States. But for two impediments, the Upper and Lower (Des Moines) Rapids, its entire course of 2400 miles would have offered an untroubled thoroughfare to watercraft.

The federal government, as well as private concerns, attempted throughout the better part of that century to alleviate the river of its barriers and to develop its rapids as a source of power. Those attempts were disappointingly unsuccessful, however, and not until the advent of the 20th Century, when the nation had matured both economically and technologically, was the …

Loci Of Invariant-Azimuth And Invariant-Ellipticity Polarization States Of An Optical System, Rasheed M.A. Azzam, N. M. Bashara

Electrical Engineering Faculty Publications

The loci of polarization states for which either the ellipticity alone or the azimuth alone remains invariant upon passing through an optical system are introduced. The cartesian equations of these two loci are derived in the complex plane in which the polarization states are represented. The equations are quartic and are conveniently expressed in terms of the elements of the Jones. matrix of the optical system. As an exple the loci are determined for a system composed of a π/4 rotator followed by a quarter-wave retarder.

Device For Obtaining From Small Ponds Water Samples Or Lagoons, J. Kent Mitchell, Elbert C. Dickey

Department of Agricultural and Biological Systems Engineering: Faculty Publications

A research project was recently initiated which requires that water quality samples be taken from small ponds and lagoons in west-central Illinois. A method for obtaining these pond water samples was desired that could be handled conveniently by one person and would not require a small boat. The pond water sampler described here was developed to satisfy this need.

The sampler developed allows one person to obtain a water sample at any desired depth while remaining on the shore. After assembling the device it may be floated to any position on the pond surface, lowered to the desired depth, and …

The Four Horsemen, Tim Brady

Publications

From 1956 until 1960, the Air Force's Tactical Air Command (TAC) fielded a team of four C-130 Hercules pilots to perform as an aerial demonstration team. The shows thrilled audiences around the United States and the pilots, known as the Four Horsemen, showed the power and maneuverability of the huge airlifters also known as troop carriers. The aircraft used in the demonstrations were taken from the inventory of whatever air base was closest to the show.

On A Wing And A Strap, Tim Brady

Publications

In 1958, as part of Operation Jingle Bells, a Hercules C-130, ferrying cargo and personnel to the United States from the Far East, encountered weather and abbreviated their flight into Langley. Little Rock Air Force Base was chosen as the alternative landing site. Getting the C-130 down onto the ground proved to be challenging when the controls for the trim system did not operate correctly. Through sweat and ingenuity, the crew got the bird landed and the personnel in the back applauded their efforts. The personnel and cargo were used as ballast to change the center of gravity. After that …

A Water Resource Management Model, Upper Jordan River Drainage, Utah, Bi-Huei Wang, James I. Felix, Rick L. Gold, Craig T. Jones, J. Paul Riley

Reports

As demands upon available water supplies increase within a river basin, there is an accompanying increase in the need to assess the downstream consequences resulting from changes at specific locations within the hydrologic system. This problem is approached in this study by digital computer simulation of the hydrologic system. Modeling concepts are based upon basic relationships which describe the various hydrologic processes. Within a hydrologic system these relationships are linked by the continuity-of-mass principle which requires a mass balance at all points. Spatial resolution is achieved by considering the modeled area as a series of subbasins. The time increment adopted …

Modification Of A Continuous Ice Crystal Replicator, Paul D. Thornley

Reports

A continuous ice-crystal replicator was modified by the addition of a gear drive to the cating wheel. This modification utilizes a positive drive force on the coating wheel rather than the friction force between the coating wheel and the film. The coating wheel operates successfully for at least 12 hours without slippage or damage to the film. Studies have uncovered several deficiencies in the replicator design which could be corrected. The correction of these deficiencies would lead to an improved quality of ice-crystal replicas. The need for continued studies in the fluid properties of Formvar solution is pointed out. Information …
