Theoretical Thermodynamic Properties Of Low Temperature Fluids, Zul Azhar Zahid Jamal

Masters Theses

The thermodynamic functions for low temperature fluids are computed using parametric integral equations and perturbation theory. Parametric integral equation N is applied to a low temperature Lennard-Jones gas. It is found that there is no significant improvement over the better known parametric integral equation C. The two parameter integral equation T is applied to a low temperature square-well potential and is found to be unsatisfactory at reduced temperatures of T*= 1.4 and 1.6, but quite accurate at T* = 2.2. The equation T results for T* = 2.2 are used as the reference system in perturbation theory computations. Tables of …

Deposition, Diagenesis, And Porosity Development Of The Middle Devonian, Lucas Formation In The West Branch Oil Field, Ogemaw County, Michigan, Scott Gregory Park

Masters Theses

The Lucas Formation in the West Branch Oil Field contains over 1000 feet of carbonates and evaporites deposited in restricted marine environments. Deposition ranged from a tidal flat environment (Richfield Member) to subaqueous basin central type deposition (Iutzi and Horner Members).

Early diagenesis of the Lucas Formation carbonates included dolomitization and related porosity development in certain depositional facies where physiochemical conditions were favorable. Significant porosity and permeability reduction occurred during burial resulting from anhydrite, celestite, and halite cementation. Calcite pseudopar and microspar (a neomorphic product) also reduced porosity.

Hydrocarbon production from the Lucas Formation in the West Branch Field is …

The Effects Of Unilateral Brain Damage On Analogical Reasoning By Stroke Patients, Letitia Lynn Gillespie

A Comparison Of Awareness Training And Competing Response Training In The Treatment Of Muscle Tics And Nervous Habits, Gregory A. Wright

Masters Theses

This study examines two components of Azrin and Nunn's (1973) habit reversal procedure in an attempt to separate the effects of awareness training from the effects of competing response training. Research (Miltenberger, Fuqua, & McKinley, 1985) has indicated that an intervention combining awareness training and competing response practice is as effective as the entire habit reversal package in suppressing muscle tics. However, because the competing response component is always administered in conjunction with awareness training, the effects of each component are obscured. Four subjects, two with muscle tics and two with nervous habits, received an intervention of either awareness training …

Intracellular Protein Degradation In A Mesophile And A Thermophile Of The Genus Bacillus, Cameron C. Hoover

Masters Theses

¹⁴C-leucine was incorporated into th e proteins of the mesophile Bacillus licheniformis and the thermophile Bacillus stearothermophilus. Aliquots of the cell suspension were treated with chloramine-T in order to decarboxylate the ¹⁴C-leucine that was released as the proteins degraded. The ¹⁴CO₂ was trapped and counted. This allowed for the determination of the extent of intracellular protein degradation at various tem peratures and at various stages of the growth cun/e. For the mesophile, the extent of degradation increased with temperature from 30° C to 55° C. For the thermophile, no significant amount of degradation occurred until …

The Effect Of Range Training On The Vocal Accuracy Of Restricted And Complete Range K -3 Singers, Jane Mary Rooks

Masters Theses

The study investigated the effects of remedial vocal training on inaccurate singers. A pretest given to inaccurate singers in kindergarten through third grade differentiated inaccurate complete range singers from inaccurate restricted range singers. Three equivalent groups of these singers were given vocal instruction through a Systematic Vocal Training method in either their low, high, or high/low range. A posttest was administered to ascertain gain scores.

The results demonstrated that the gain scores of the restricted range singers were significantly greater than those of the complete range singers. The results also indicated that the scores in the low range of the …

The Evolution Of Text Formatting Languages, Dirk Herr-Hoyman

Masters Theses

Text, as seen in books and magazines, can take on three forms: string, graphic (two-dimensional), and image (digitized pictures). Text formatting processes text into a representation suitable for printing. Since a printer is really a computer, this representation is machine code for the printer. ASCII is one such code.

Six historically significant text formatting languages are surveyed: Runoff, Troff, TeX, Bravo, Scribe, and Postscript. The emphasis is on the text types available and the code generated. The main evolutionary forces are the changes in printers. Comparisons are made with programming languages.

Each of the six languages has ASCII as its …

Each one of the field supervisors demonstrated the ability to fit his/her personality to different situations. Each was different in his/her basic styles but yet shared several common traits. Finally, it …

Responding Under Homogeneous Versus Heterogeneous Chained Variable-Interval Schedules, Stephen P. Starin

Masters Theses

Four pigeons responded under chained variable-interval schedules in which the required response topographies were either similar [i.e., a homogeneous chain] or dissimilar Ci.e., a heterogeneous chain]. Subjects were exposed to all possible combinations of initial-link key pecking or treadle pressing and terminal-link pecking or treadling. Three of four subjects displayed higher initial-link response rates under the homogeneous chains. The present results were explained in terms of an induction effect in which the strengthening effect of reinforcing a particular terminal-link response topagrapahy generalizes to similar responses earlier in the chain, but not to topographically different responses.

Structural Geology And Geothermal Investigation Of The White Sulphur Springs Area, Montana, William G. Gierke

Masters Theses

Sevier thrusting in the White Sulphur Springs area was associated with left-lateral movement along the Lewis and Clark line . During Middle Miocene time, the Lewis and Clark line exhibited right-lateral movement, forming extensional features that either truncated Sevier structures or followed preexisting Sevier zones of weakness.

The Smith River Valley is a pull-apart basin that is filled with Tertiary volcanic ash and clay-rich sediments that are thermally nonconductive relative to surrounding rocks.

Hydrothermal activity in the area is associated with a structurally controlled circulation system accompanied by a high thermal gradient. Thermal discharge is constrained along the north-trending White …

The Effect Of Well Efficiency On In-Situ Permeability Test Results, Scott T. Dennis

Masters Theses

The purpose of this study was to determine what effect well efficiency has upon the results of in-situ permeability tests.

Several in-situ permeability tests were performed on wells during various stages of their development. The well efficiency was determined each time an in-situ test was performed. An accurate value of permeability was determined by performing local aquifer pumping tests. The accuracy of the results of the in-situ tests with respect to the aquifer pump test results were then compared to the efficiency of the well at the time of the test.

Test results showed that a linear relationship exists between …

A Comparison Of Wais-R Scores With Wais-R Scores For Mentally Handicapped Students With Iqs Below 70 And For Regular Education Students, Kimberly A. Brennan

Masters Theses

The purpose of the present study was to investigate the utilization of WISC-R scores as a basis for placement and continuation of services for mental retardates in special education classes throughout their school careers. A comparison of the WISC-R Verbal, Performance, and Full Scale IQs with the WAIS-R counterparts and a statistical analysis was conducted. Regular education students were also tested to determine if the two scales were equal.

The WAIS-R was found to yield higher Verbal and Full Scale IQ scores, but comparable Performance IQ scores. These results suggest that the differences between the two instruments for children of …

A Study-Support Program For High-Risk, Black College Freshman Enrolled In A General Psychology Course, Angela Michelle Williams

Masters Theses

As a replication of Jackson's (1984) work, this research compared the performance of three groups of college freshmen. The groups consisted of black, high-risk students who voluntarily enrolled in a study-support group because of their initial quiz scores. The support program required the students to study each week's psychology objectives in four smaller segments, rather than studying all the week's material at once. The assumption was that this would increase the students' contact with the study material and improve their performances. An ABA design was used. The participants in the support program received higher quiz scores and final grades than …

The J-Curve: An Empirical Investigation Of The Trade Balance And Balance Of Payments In Seven European Countries, Sabine Beate Bomke

Masters Theses

The effects of exchange-rate changes on the trade balance and the balance of payments of selected European countries is examined in this paper. Of particular interest are estimates of the existence and length of the J-curve effect, which describes the curve the trade balance may follow over time after devaluation. Contrary to popular expectations, the trade balance may deteriorate further after devaluation before "turning around" and improving.

Quarterly data from 1973 to 1985 for Belgium, Denmark, France, West Germany, Ireland, Italy and the Netherlands were used in this study. Out of a total of 84 realignments the J-curve was observed …

Performance Predictions For Oil Reservoirs Under Water Influx, Briareus Mitchell Wilkinson

Masters Theses

"The intent of this thesis is to develop a program that will give reasonable recovery predictions for oil reservoirs under water influx. The main advantage is to avoid the massive storage and computational requirements of numerical simulators while achieving roughly comparable results. There are many methods already in existence that have not received their full benefit, mainly because they were developed prior to the recent advances of the computer age. This thesis therefore brings some already proven methods together with new techniques in a program which, with the aid of the computer, stimulates new life in these methods. The main …
