Stability Constants Of Naco3-, Naso4- And Kco3- In Water At 25°C, Frank Dennis Blum

Masters Theses

A new method for determining ion association constants in aqueous solutions using ion selective electrodes has been developed. This method has been applied to the NaCO₃^-, NaSO₄^- and KCO₃^- ion pairs at 25°C. Association constants for NaCO₃^- and NaSO₄^- were determined at various ionic strengths and extrapolated to zero ionic strength to yield 2.2 ± 0.2 for NaCO₃^- and 5.3 ± 0.4 for NaSO₄^-. Values for the association constants at an ionic strength near sea water (I=0.70) were calculated to be 1.7 ± 0.1 …

It is the conditions that caused a four-year time schedule between application and construction that are focused upon.

This study attempts to chronologically show the life of the Georgetown project and the events that have made it a learning situation. It is also …

A Comparative Study Of The Effects Of Different Types Of Media On Selected Fifth Grade Students At Franklin Elementary School, Mattoon, Illinois, Lester Raymond Burton

Masters Theses

Instructional media is usually used as a supplement to verbal and printed instruction. It is used for the purpose of illustration, exemplification, motivation, and for clarification. Filmstrips, 16mm films, charts, maps, and still pictures, library books, and resource units help students understand their social world.

No one teaching tool reaches the set goals in Social Studies classes. A comparison of different types of media effectiveness in improving student interest, in stimulating class discussion, and in helping to fix vocabulary is the goal of this study.

Identification of the media which produce the best student success provided the Social Studies with …

Videotape Feedback And Its Effects On Two Communicational Modalities, John Joseph Benda

Masters Theses

The present study was concerned with the applicability of various videotape feedback procedures on two communication modalities. The communication modalities studied dealt with the visual and auditory orientation of 80 college students.

The vast and, for the most part, positive findings associated with videotape feedback have fascinated therapists for the last couple of years. However, for the most part, videotape feedback has been used with individuals without taking into consideration the different ways these individuals communicate and/or learn. The purpose of the present experiment was to analyze the various aspects in which individuals communicate. Once their communicational modality was established …

Transfer Of Serial Position Effect To Paired-Associate Learning, James Lloyd Beckles

Masters Theses

The experiment was designed to evaluate the role of position in serial learning. In the position learning task, subjects learned two serial lists presented alternately, then learned a subsequent paired associate list consisting of items of the previously learned serial list. The paired associate list contained three types of pairs; the same position-same pair, different position-same pair, and different position-different pair. The findings of the experiment supported the position hypothesis that if position is the cue for the recall of the item in a serial list, then, a subsequent paired associate list that is made up of the two previously …

The Effect Of Ergosterol On The Desaturation Of 14c-Labeled Oleic Acid In Tetrahymena, Maynard E. Neville Jr.

Masters Theses

The ciliated protozoan Tetrahymena pyriformis-Strain W desaturated ¹⁴C-labeled fatty acid substrate in both sterol supplemented (ergosterol) and nonsupplemented cultures. Cis-octadecenoic acid (¹⁴C-9-18:1), when added to the medium during the log phase of growth, was incorporated into the cells and also desaturated at the Δ⁶ and Δ¹² positions. The ¹⁴C labeled substrate and products, linoleate (9,12-18:2) or linolenate (6,9,12-18:3) were recovered and separated by silver-nitrate Unisil column chromatography. Initially, recovery of ¹⁴C compounds varied widely when expressed as the percent of total counts per minute recovered from column chromotography, and a variety of …

The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace

Masters Theses

A total of 38 Mus musculus were used to compare superovulation to normal ovulation in three different areas of the reproductive cycle. The areas studied include the fertilization and abortion rates, alternation of ovarian function, and normalization of estrus cycling. No statistically significant differences were noted between the two groups in either fertility rates or abortion rates. A distinct difference was noted in alternation of ovarian function. Normally ovulating mice showed a distinct right or left preference in the number of ova ovulated from each ovary. Animals showing a left preference exhibited approximately a 2:1 ratio and animals with a …

A Cytogenetic Study Of Xx/Xy Chimerism And Other Anomalies Of Bos Taurus In A Sampled Dairy Herd, Ferne M. Rogers

Masters Theses

The establishment of normal chromosomal patterns for a wide range of plants and animals has led to the recognition of abnormalities as well as their relationship to phenotypic irregularities. Research dealing with the expression of human karyotype is of prime interest; but, closely rivaling that is the genetic study of domestic animals which are of economic importance to man.

One observed anomaly which has come under scrutiny by cytogeneticists is that of the female member of a heterogeneous bovine twin pair, the freemartin. This is a sterile animal with internal morphology showing varying degrees of intersex. Cytogenetic studies reveal XX/XY …

An Evaluation Of Productivity And Efficiency In Work Scheduling In A Public Works Department, Kraig L. Gordon

Masters Theses

“Managers throughout the world frequently associate the meanings of productivity and efficiency with the capabilities and performance of employees. This approach is limited since productivity entails far more than the output of the labor force. The factors affecting productivity need evaluating to determine the significance they plan in the overall process.

Industry has attempted to improve its productivity posture by utilizing a multitude of concepts. Some of these concepts are time and motion studies and process planning. However, in the public sector, literature shows that little has been attempted to improve the productivity in public organizations.

The greatest portion of …

Dynamic Pullout Resistance Of Anchors Buried In Dry Sand, Chris John Veesaert

Masters Theses

"The vertical pullout resistance of buried anchors subjected to dynamic loading was investigated by means of a laboratory model study. A dry uniformly graded sand, compacted by vibration to 92% of its relative density, was used as the test medium. Tests were performed in a 24-inch square tank using 3.0 and 5.0-inch diameter half and full-anchors. The anchors were tested at depths ranging from 5.0 to 21.0 inches.

It was assumed that the dynamic failure mechanism of earth anchors was the same as the static failure mode, and not distinct behavior. Thus static tests, i.e., tests using a constant strain …

Petrology Of The Rockport Quarry Limestone (Middle Devonian Traverse Group) Alpena, Presque Isle And Montmorency Counties, Michigan, Charles Willard Cookman

Masters Theses

The basal unit of the dominantly carbonate Traverse Group, the Bell Shale, is gradationally overlain by the Rockport Quarry Limestone which has a thickness of approximately 14 m. The Rockport Quarry Limestone is composed of a dark unrestricted marine subtidal organic-mud packstone facies, comprised of an algal-mat-bearing coral packstone subfacies and a shallower water crinoid-bryozoan grainstone subfacies; a shoal forming stromatoporoid biolithite facies; and a lagoonal micrite facies comprised of a subtidal dense subfacies containing gastropods, ostracods, and calcispheres, and an Intertidal to supratidal fenestral subfacies. The local facies tract reconstructed for the Rockport Quarry Limestone is interpreted to be …
