A Comparison Of The Perception Of Juxtaposed Tones In Newspaper Images When Screened With Conventional And Random Dot Screens, Sylvia Monteiro

Theses

The halftone process has been the conventional means of reproducing photographic artwork on newsprint. The use of relatively coarse screen rulings, dictated by the paper characteristics, produces an image with a noticeable dot pattern. Furthermore, the printing process is susceptible to extreme dot gain variation, which affects tone reproduction and the pictorial communication of the image. There were good reasons to suspect that a random dot screen could give more consistent tone rendition than a conventional halftone screen. A comparative study of the consistency of perception of conventional and randomly screened images when printed on newsprint has not yet been …

Image Quality As A Function Of Unsharp Masking Band Center, Chia-Chin Liu

Theses

Unsharp masking is an image enhancement technique used to obtain a Modulation Transfer Function (MTF) greater than unity within a given spatial frequency band. In unsharp masking, the mask forms a slightly blurred version of the original image. The result is more severe in the high frequency region than at low frequencies. The final image is made by combining the original positive and the blurred negative images. The subjective quality of images resulting from unsharp masking is a function of the frequency response of the human eye. This study evaluates the unsharp masking technique by implementing the Subjective Quality Factor …

The Law And The Nurse Anesthetist, Beverly Ann Krause

Theses

Should the surgeon, as "captain of the ship", be liable for the negligent acts of the Certified Registered Nurse Anesthetist? The Certified Registered Nurse Anesthetist is a highly skilled and educated nurse and is far more informed about anesthesia than the surgeon . The surgeons resent this needless liability , and because of this, the use of Certified Registered Nurse Anesthetists to administer anesthetics might decrease.

To prove that the hypothesis was correct, several methods of research were done . A content analysis showed that the courts are divided on their decisions. There have been many decisions absolving the surgeon …

Obstetrical Anesthesia Curriculum Project, Margaret A. Wittman

Theses

The project idea stems from my work as a clinical instructor in nurse anesthesia. I have noticed that there is a great disparity between the didactic work done in the classroom and the clinical work done in the operating rooms. Instead of applying the classroom material to the actual case work, thereby making it important and meaningful to the student, the link between the two areas is virtually ignored. The aim in developing my project is to remedy this situation. In designing a curriculum for obstetrical anesthesia, I will attempt to utilize teaching methodologies which will not encourage rote memorization …

Prediction Of Small-Scale Densities Using The Chemical And Optical Spread Functions, David S. Cline

Theses

Development adjacency effects and optical spread in photographic systems cause difficulties in predicting small-scale densities. These effects can be quantified as spread functions. The optical spread func tion describes the light scatter of the film. The chemical spread func tion describes the lateral diffusion of development- inhibiting and dev elopment-accelerating reaction products. These spread functions can be used along with the sensitometry and covering power relationships of the system to predict small-area densities from the object exposure profile. A study based on C. N. Nelson's work was undertaken to develop a math ematical model that uses the optical and chemical …

Investigation Of A Method To Increase The Sensitivity Of Counter-Current Immunoelectrophoresis Using Direct-Contact Photography, James E. Hohenberger

Theses

Counter-current Immunoelectrophoresis (CIE) has been used to detect bacterial capsular polysaccharides in both cerebrospinal fluids and blood serum of children with systemic meningococcal diseases. The sensitivity of the method depends upon the titre of the antisera. It was found that the sensitivity of CIE could not be increased by the method of direct-contact ultraviolet photography. The sensitivity could be increased by one serial dilution, on the average, by the treatment of a 0.25% tannic acid wash for 15 minutes.

The Hypoxia Screen As An Indicator Of Alterations In The Number Of Centeral Cholinergic Recpetors Inuduced By Chronic Acetylcholinestrerase Inhibition, Kathleen B. Wallace

Theses

Chronic administration of diisopropyl fluorophosphate (DFP) at 72 hour intervals for a total of 14 doses resulted in a reduction in the number of central muscarinic receptors in mice as measured by the specific binding of [3H]Quinuclidinyl benzilate (QNB) to cortical tis sue homogenates (pmole/mg protein). The number of cholinergic receptors were reduced significantly by 12% in DFP treated animals (0.687 + 0.018 pmoles/mg) as compared to vehicle treated controls (0.781 +0.016 pmoles/ mg) after the sixth dose of DFP (Day 17).
