Reliability Of Existing Bridge Inspection And Evaluation Procedures, Leroy R. Klouser

Theses

In general, bridge inspection is subjective since visual observation and the basic inspection tools cannot reveal hidden structural deterioration, such as corrosive and delaminated rebars embedded in the concrete. Based on the NJDOT SI&A report, a scale (9 to 0) is used in rating five bridge components. This approach seems reasonable, since the time span, manpower and cost are limited throughout the counties of New Jersey. On the other hand, based on the scaling system, the SI&A reports can vary depending upon the exposed surface appearance and the experience of the bridge inspector.

Morphological Analysis Of Microvessels Using High Voltage Electron Microscopy (Hvem), Ibm Personal Computer And 3-D Reconstruction Software, Wieslaw Slawomir Krajewski

Theses

The mesenteric arterioles (outer diameter < 100 µ) from a normotensive and a hypertensive dog were perfused in situ, excised, post-fixed and embedded in Spurr medium block. Thick serial cross sections (0.5 µ) of the vessels were obtained from hand formed mesas and placed on Formvar coated slot grids.

The cross sections were subjected to High Voltage Electron Microscopy (HVEM) and five or more electronmicrographs were taken to cover the individual cross sections. The prints of electronmicrographs were linearly enlarged (3X) and made into photomontages of sections. The membrane contours in the montages were traced on transparent overlays, producing polygons which in turn were traced on GTCO digitizing pad. All polygons were labeled, color coded and stored in IBM PC's filing system. The vessels were reconstructed from up to 100 whole cross sections and subjected to cell compartmentalvolume analysis.

The emulator communicates with the IBM Personal Computer through the I/O channels on the mother board instead of the serial port, so its speed is much faster than that of the serial port. …

Use Of Latex Modified Concrete For Repairs And Overlays, Chen-Hoang Lo

Theses

Latex modified concrete and polymer concrete have been widely used for bridge deck overlays and crack repairs for the past decade. In recent years, many of these repaired structures were found to be defective. The causes of these failures are not clearly confirmed. Some blame the quality of the latex products while manufacturers accuse the contractors of improper placement and/or surface preparation. While most of these failures largely appeared to be debonding and delamination of the overlays, excessive cracks, possibly shrinkage cracks, were also reported in the overlaid LMC.

To evaluate the suitability of using latex modified concrete for crack …

Optimizing Tone Production On A 300 Spot Per Inch Laser Printer, James R. Hamilton

Theses

Digital halftones as output on plain paper are the focus of this study. A new terminology is suggested to allow proper description of digital halftones. The most important of these terms is the use of "addressability" to replace the often misused term "resolution." Also important is the use of the term "spot" rather than "dot" to describe addressability. A means of properly describing digital halftones is suggested to avoid confusion with analog (ie., conventional photographic) halftones. Halftone patterns were created to test the efficiency of different designs at 300 spot per inch addressability on a laser printer. The page description …

N-Values And Paper Opacity, Robert Eric Aronson

Theses

The n-value is a factor which allows the Murray-Davies equation to be correctly solved for physical dot area or tint density. This equation becomes known as the Yule-Nielsen equation when the n-value is used.

Many variables affect the value of n; paper characteristics, screen ruling, even the equation variables themselves. The level of solid ink density may have a very significant effect on the n-value. This fact, although suspected, has not been investigated until now.

A study into this variance was undertaken in Appendix II with a method for adjusting the value of n to a standard solid ink density …

Covering Power And Speed Characteristics Of Silver Bromide Core/Shell Emulsions Etched With Sodium Thiosulfate Solution, Julie C. Bishop

Theses

A pure silver bromide 0.55µm core/shell emulsion of high internal sensitivity and low surface response was evaluated for its covering power and speed characteristics when the shell was removed in a 0.05M sodium thiosulfate etching bath following exposure. The etched core/shell emulsion was chemically developed and compared with the 0.36µm AgBr core alone at approximately constant developed silver weight per unit area at maximum density. It was observed that the etched core/shell emulsion displayed ~0.44 Log H units greater speed than the core alone when both were examined at approximately the same covering power.

A Christian Counseling Handbook For The Lay Counselors, Debra K. Olson-Demmie

Theses

Counseling psychology advocates a position of neutrality where religious issues are concerned. This position appears benign at first glance, but upon closer examination we find that psychology has been strongly influenced by modern humanistic thought. In his book Psychology as Religion: The Cult of Self-Worship, Paul Vitz (1977) states, "Psychology has become as religion, in particular, a form of secular humanism based on the worship of self" (p. 9). Vitz alleges that humanistic psychology is being practiced as an anti-Christian religion.

Christian mental health and pastoral care providers need to be alert to the infiltration of humanistic thought into psychological …
