Distribution Of Flurescent Latex Particles Following Clearance From The Hemolymph Of The Freshwater Crayfish,Orconectes Virilis (Hagen), Douglas Merrill, S. Mongeon, S. Fisher Jan 1979

Distribution Of Flurescent Latex Particles Following Clearance From The Hemolymph Of The Freshwater Crayfish,Orconectes Virilis (Hagen), Douglas Merrill, S. Mongeon, S. Fisher

Articles

By using a novel technique we have been able to follow the clearance and distribution of fluorescent latex particles injected into both the midventral sinus and pericardial sinus of the freshwater cray-fish,Orconecte virilis. The fluorescene of various tissues was determined over post-injection periods ranging from 1 h to 20 days. Particles were rapidly removed from the hemolymph (Figs. 1 and 2) and accumulated in the heart (Fig. 3), antennal glands (Fig. 4), gills (Fig. 5) and, to a lesser extent, hepatopancreas (Fig. 6). Other tissues contained fluorescence in concentrations proportional to their supply of hemolymph.


Effect Of Blocking Protein Synthesis At Nonpermissive Temperatures On Temperature-Sensitive Deoxyribonucleic Acid Mutants Of Escherichia Coli, Irene Evans, N. Forrest, A. Lawrence Jan 1979

Effect Of Blocking Protein Synthesis At Nonpermissive Temperatures On Temperature-Sensitive Deoxyribonucleic Acid Mutants Of Escherichia Coli, Irene Evans, N. Forrest, A. Lawrence

Articles

When protein synthesis was blocked in temperature-sensitive deoxyribonucleic acid synthesis mutants of Escherichia coli at nonpermissive temperatures, it reduced the amount of apparent subsequent chain elongation to approximately half that observed in the mutants either at nonpermissive temperatures alone or when protein synthesis was blocked at the permissive temperature. Blocking protein synthesis at the nonpermissive temperatures for periods of 40 min caused the loss of ability to reinitiate deoxyribonucleic acid synthesis at the permissive temperature.


Patterns Of Drinking Among The Deaf, Morton Isaacs, Gerard Buckley, Donna Martin Jan 1979

Patterns Of Drinking Among The Deaf, Morton Isaacs, Gerard Buckley, Donna Martin

Articles

Thirty-nine White deaf persons functioning normally within the general hearing community were surveyed on a variety of factors concerning their use of alcohol, and compared to the data from two comparable hearing samples reported previously in the literature. No significant differences were found between the deaf and heharing samples on patterns of drinking or other parameters of alcohol use. Heavier alcohol use among the deaf correlated significantly with reported frequency of driving after having drunk too much, age of having had first drink, ever having been drunk, feeling guilt over drinking too much, and others criticizing the respondent for drinking …

Readability Determination Using Superimposed Random Noise Patterns, Michael Dennison Jan 1979

Readability Determination Using Superimposed Random Noise Patterns, Michael Dennison

Theses

A readability gauge was constructed which objectively gauges the readability of printed matter. In the past such gauges have been produced using photographically created noise. In this study a gauge was constructed using noise generated by a computer. This gauge was evaluated and compared with a gauge produced using the photographic technique of noise generation. The computer generated gauge proved to be as good as the photographic gauge at detecting differences in legibility of printed type. It was also found that the only two causes of variability in the legibility samples used were letter size and letter contrast. Using only …


Modifications Of A Herrnfeld Sensitometer For Interimage Studies, Charles Tobin Jan 1979

Modifications Of A Herrnfeld Sensitometer For Interimage Studies, Charles Tobin

Theses

An available Herrnfeld Sensitometer has been rebuilt and modified to include a six position filter wheel, three narrow band interference filters, a separate D.C. power supply, and a central control panel. The modified sensitometer expedites the single layer exposure of color film. The system accomplishes this by using interference filters whose band-width peaks are matched to the peak spectral sensitivity of each emulsion layer to be exposed. A D.C. power supply has been included to eliminate lamp ripple caused by the oscillations that occur in the A.C. line. In depth experimentation (approximately 20 rolls of film) produced exposures closely approximating …


Evaluation Of Turbine Blade Root Damping, Curtis Beck Jan 1979

Evaluation Of Turbine Blade Root Damping, Curtis Beck

Theses

A test program has been conducted to measure the vibration damping of three designs of steam turbine blades. These blades were tested in their root attachments, sectioned from retired rotors. Blade loading was accomplished in a new type of blade damping test rig and damping was evaluated in the lowest tangential and axial blade modes. The test environment was room temperature air. The damping rig concept and development is presented in detail as well as results of an intensive test program. The blade designs are designated as Types A, B, and C, where Types A and B were of a …


Concur: A High-Level Language For Concurrent Programming, Karen Anderson Jan 1979

Concur: A High-Level Language For Concurrent Programming, Karen Anderson

Theses

A language CONCUR is defined which permits the definition and initiation of asynchronous processes. The language was inspired by Modula, a language proposed by Wirth for realtime programming. CONCUR removes Modula's restrictions on the placement of process declarations and invocations in order to study the implications of process support more fully- Most of the other sophisticated features of Modula, such as modules, structure types, and procedures, have also been removed to focus attention on processes and their particular requirements. A general methodology is suggested for concurrent programming, and several sample programs are presented which demonstrate concurrent programming with CONCUR. Finally, …

A Software Development System For The Motorola M6800, John Michael Moore Jan 1979

A Software Development System For The Motorola M6800, John Michael Moore

Theses

The goal of this project was to produce a useable software development system for the Digital Group M6800 microcomputer. The design was to have implemented the command language of the Digital Group Z-80 operating system and and have the capability of assembling source programs written using the Motorola M6800 assembly language mnemonics. The program developed to fulfill these requirements was assembled using the Motorola M6800 cross assembler and occupies approximately 7K bytes of memory. The functions provided include an editor package for the entry and modification of source programs, an assembler which meets the design goal and a debugger package …


A Study Of The Mechanism Of The Sabattier Effect, Steven Oshry Jan 1979

A Study Of The Mechanism Of The Sabattier Effect, Steven Oshry

Theses

Conditions for producing the Sabattier effect in Eastman fine grain release positive 5302 film were established. Modifications of the second developer to develop more internal latent image by the addition of potassium iodide or to increase solution ~ physical development by the addition of sodium thiocyanate and sodium sulfite were performed. These modifications made no significant change in the Sabattier effect. When chemical fog (from sodium borohydride) was substituted for the exposure during development, no reversal corresponding to the Sabattier effect was obtained.

Second Stage Autoradiographic Amplification Of Developed Underexposed Tri X Emulsion Images, David Dempster Dec 1978

Second Stage Autoradiographic Amplification Of Developed Underexposed Tri X Emulsion Images, David Dempster

Theses

A series of del iberately underexposed Kodak Film Type Tri-X negatives were first, conventionally developed, the image silver made radioactive with sulfur-35 thiourea, and by using an autoradiographic technique, the image recovered on X-ray film. The resolution and characteristic curve parameters of the final image compared to those of the original donor image were determined by varying the secondary exposure time (contact time between radioactivated film and x-ray emulsion), type of x-ray films and exposure levels. The Tri-X Pan emulsion donor image was amplified using Kodak "NMC", "MA" and "RP" X-ray films as receivers. "NMC" was slightly preferable to "MA", …


An Experimental Comparison Of Emulsions Of The Same Type Of Different Iodide Levels, Seilay Wong Dec 1978

An Experimental Comparison Of Emulsions Of The Same Type Of Different Iodide Levels, Seilay Wong

Theses

Single run neutral type iodobromide emulsions of 1, 5 and 10 mole % were made similarly. On development to 0.7 gamma with Kodak developers D23 and DK50, it was found that the 10% iodide emulsion had faster speed than the 1% iodide emulsion but yet its granularity was no greater than the 1% iodide emulsion. There is no evidence that the performance in D23 as compared to DK50 was improved with increasing iodide percentage.
