Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton
Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton
Masters Theses
Chapter I
Introduction
In discussing the basis for teaching high school biology, Van Deventer1 states, "...the present typical course in high school biology serves adequately neither the terminal student nor the college entrance student." He holds that today's courses present watered-down versions of college courses to the student before the intelligence of the student has matured enough to grasp such subject matter. As a result there is very little carry-over value from such courses, and the students may even develop a dislike for biology. This study constitutes an effort to understand these problems and to devise ways of solving …

Certain Trace Element Distribution In The Searchlight, Nevada Quartz Monzonite, Clark County, Nevada, Jai Nandan Shrivastava
Certain Trace Element Distribution In The Searchlight, Nevada Quartz Monzonite, Clark County, Nevada, Jai Nandan Shrivastava
Masters Theses
"The once prosperous gold, silver, copper and lead mines of the Searchlight mining district, Nevada, are situated along the south and western margins of a large quartz monzonite body. This intrudes the Precambrian gneisses and younger lava flows. Associated mineral veins show an eccentric type of zoning around the intrusive.
Seven rock samples of the quartz monzonite representing different parts of the intrusive were analyzed petrographically and spectrographically. Modal analyses and various types of rock alteration were investigated petrographically. Spectrochemical analyses of the rock samples and their major minerals were carried out for certain trace elements. A semi-quantitative method was …

Factors Of The Microclimate Affecting The Activity Of Fox Squirrels In Southwestern Michigan, Frederick K. Courville
Factors Of The Microclimate Affecting The Activity Of Fox Squirrels In Southwestern Michigan, Frederick K. Courville
Masters Theses
The fox squirrel, Sciurus niger rufiventer, is an important small game animal throughout much of the Midwest. Within the last thirty years several scientific investigations have been focused on this animal, the result being that its life history and ecology are fairly well known.
Concerning the range of the fox squirrel, D. L. Allen (1943:33) states that, in Michigan, the range began to increase with the advent of the pioneers. Baumgartner (1940) and J. M. Allen (1952) noted similar occurrences in their respective states, Ohio and Indiana. In Kansas, the fox squirrel, aided by agricultural land-use, has spread westward throughout …
Notes On The Tardigrades Of Southwestern Michigan, James J. Sawtell
Notes On The Tardigrades Of Southwestern Michigan, James J. Sawtell
Masters Theses
Introduction
Tardigrades, comprising fewer than 350 species, are microscopic animals which inhabit mosses, lichens, and algae. Tardigrades or "water bears" are distributed throughout the world. These invertebrates are found in fresh-water substrates (Cooke, 1959; Marcus, 1939, Moore, 1939; Pennak, 1940), marine substrates (Chitwood, 1951; Green, 1950; Jeannel et al., 1940; Marcus, 1927, 1946; Pennak, 1953:240; Wieser, 1959) and terrestrial habitats (Cuenot, 1929; Marcus, 1960; Rodriguez-Roda, 1948; Pennak, 1953:240). The "water bears" have also been found in the psammolittoral zone where they live between grains of sand, (Pennak, 1940) and there feed on algal cells (Marcus, 1929). Tardigrades puncture the cell …

The Separation Of Selected Radioactive Fission Products By Electrodialysis, Jerry David Vie
The Separation Of Selected Radioactive Fission Products By Electrodialysis, Jerry David Vie
Masters Theses
"The recent advent of nuclear energy has opened an era of almost unlimited power and countless problems. A problem of extreme importance is the recovery of unburned nuclear fuel and the claiming of transmutation products, such as Pu239 and U233, from the irradiated fuel elements. The chemical processing must also separate the fission products from the fissionable material if the fuel is to be used again.
At present, the irradiated fuel elements are stored for 90 to 120 days to allow the intense short half-life activity to decay. After "cooling down", the nuclear fuels are separated from …
Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.
Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.
Masters Theses
"Lenticular bodies of massive limestone, flanked by thin crinoidal beds, crop out in southwestern Missouri and northwestern Arkansas. They are within the St. Joe limestone of the Lower Mississippian.
Strata underlying these bodies typically are down-warped, those on the flanks lapping against, finally passing completely over the limestone core. Dips away from the “reef” are commonly around 5 degrees, but reach as much as 30 degrees. Conglomeratic detritus, originating from the core, occurs in flanking beds at their contact with it.
Thin sections of these masses show no more than 15 per cent of the limestone to consist of fossil …

Business-Sponsored Films For Physical Science, Bertha Elizabeth Slye
Masters Theses
For many years business-sponsored films have been used widely in instruction in the science classroom. Because of the potential of the films in helping teachers bridge the gap between the fundamental teaching of scientific principles, and the applications found in the actual experiences of the student's consumer world, requests for them have often exceeded the output of those that are educationally sound. In the last decade in particular, the development of atomic and space technology, as well as the growing interest in science, have made it necessary to teach science beyond the confines of information in the ordinary science textbook. …

A Review Of Fossilization Processes In Different Sedimentary Environments (With Special Reference To The Time Factor Of Deposition Of Ore Minerals Associated With Fossil Material, In Particular The Coprolitic Phosphate Deposits), Giovanna Reggiori Ligasacchi
Masters Theses
"This thesis offers a cross/section through some principal fossilization processes involving organic matter (animals and plants) during and after sedimentation. The influence of different environments during fossilization is considered. The chemical composition of some classes of living invertebrates and plants is compared with the chemical composition of same organisms as found in consolidated sediments as fossils.
Some literature on carbonates, oxides, silicates, phosphates, and sulphides in fossils is reviewed with particular attention to those instances where the fossils are associated with ore minerals. Special consideration is given to the occurrence and composition of fecal matter in recent and consolidated sediments. …
Bonded Joint Strength Versus Loading Rate, Charless William Fowlkes
Bonded Joint Strength Versus Loading Rate, Charless William Fowlkes
Masters Theses
"The purpose of this investigation was to determine the influence of the rate of loading variable on the apparent shear strengths of joints bonded with some of the currently available metal-to-metal adhesives. The effects of this variable are sometimes neglected by testing laboratories. The results of an experimental evaluation of the mechanical behavior of a group on modern metal-to-metal adhesives as a function of the rate of load application are used to more accurately establish the importance of rate of load considerations in adhesive joint testing. An attempt is made to explain observations of other investigators engaged in adhesive joint …

The Effects Of Manifest Anxiety On Stuttering Adaptation, Joseph Agnello
The Effects Of Manifest Anxiety On Stuttering Adaptation, Joseph Agnello
Masters Theses
I. Introduction
When stuttering behavior is viewed as a problem in learning, the phenomenon of adaptation frequently receives attention. A standard adaptation experiment consists of having the person who stutters re-read the same passage, or a passage of equal difficulty, a specified number of times. Under these conditions a relative reduction1 in stuttering frequency usually occurs. Experimentalists and clinicians alike have long been puzzled as to why this decrement takes place, since stuttering is generally considered by many writers2,3 as a self-reinforcing disorder; that is, stuttering produces more stuttering.
The present experiment was designed to investigate the effects, …

Operational Characteristics Of A Small Sewage Oxidation Lagoon, Karlheinz C. Muhlbauer
Operational Characteristics Of A Small Sewage Oxidation Lagoon, Karlheinz C. Muhlbauer
Masters Theses
"With the rapidly increasing population in the United States the adequate disposal of sewage has become one of the major technical problems which the sanitary engineer has to solve. In most areas it is no longer acceptable practice to discharge domestic sewage or industrial waste products directly into streams or lakes because of the resulting pollution of the water, which may later be used for drinking or recreational purposes. Many larger cities have, therefore, adopted some method of sewage treatment which renders such wastes safe and unobjectionable before they are discharged into a lake or stream. Most of these methods …
