A strength of materials type solution is obtained for the shear stress state in the adhesive layer of a bonded cantilever beam subjected to an end load.

The shear stress is constant through the thickness of the adhesive layer and varies from zero at the fixed end to a maximum value at the free end. This maximum value can, under certain conditions, be calculat....

Laboratory experiment: were carried out to evaluate the effectiveness of antibacterial substances and antibiotics against Thiobacillus ferrooxidans, the organisms responsible for bacterial mediated acidic mine drainage. Twenty two antibiotics (obtained from Lilly and Co.) and two antibacterial substances were added to bacterial culture ATCC 19859 grown in ....

The activated sludge wastewater treatment process depends upon the formation of biological floc for effective liquid-solids separation, nutrient stabilization and sludge dewatering. Continued research into floc formation, intrafloc interactions and floc hydrodynamics is necessary for improved understanding of the activated sludge process. The overall goal of this resear....

A 4.0 Kb (2.64 Mdal) plasmid was isolated from a fowl cholera strain of Pasteurella multocida (the Larsen strain) by alkaline lysis and cesium chloride purification. The plasmid, designated pLARâ1, was characterized in terms of its size and restriction sites. The restriction patterns produced by fourteen endonucleases were used to generate a restriction map. Fiv....

A room as a symbol of past history of the place, the museum as analogy for passing on knowledge by a book and many questions subjected to a house, but also to architecture and much more to my own person. This is the content of this Thesis book which, by its examples, cannot give definite answers but is to lead to new questions while their response is justified by a subj....

Thyroxine was observed to stimulate the incorporation of radiolabeled amino acids into protein of cell-free Liver systems from treated normal and hypothyroid rats. However, the in vitro addition of the hormone only had a stimulatory effect, though quite erratic in magnitude, on the normal system. This difference in response has not been explained.

The h....

A study of several techniques that may be used to solve exterior electromagnetic scattering problems was made. Analytical methods, moment methods, sub sectional methods, probabilistic methods, integral equation methods, and analog/hybrid computer methods were considered in the study to determine the best method to use in a general approach to scattering problems. It was....

The acceptance rate of a runway at an airport can be considerably increased by proper location of high-speed exit taxiways along the runway downrange. The location, geometry and the exit angle of these high-speed exit taxiways play a crucial role in the successful negotiation of the turnoff and in reducing the runway occupancy times. This reduction in ROT increases t....

Since the collapse of modernism, the study of traditional urban design principles have increasingly drawn the attention of architects interested in the development of an enduring theory and practice of architecture. This thesis supports the position that an architect be able to comprehend the concept of . a city as a prelude to architectural design. As the architect Fra....

A study was made in an effort to seek an evaluation of the "How to Study" instruction given to Freshmen Air Force ROTC Cadets at VPI, and also to determine the degree to which Corps life aided or hindered these Cadets in their academic pursuits in both their freshman and sophomore years.

Utilizing two techniques, continuous observation and a questionnaire, a ....

The passive components such as inductors and capacitors are bulky parts on circuit boards. Researchers in academia, government, and industry have been searching for ways to improve the magnetic energy density and reduce the package size of magnetic parts. The âconstant-fluxâ concept discussed herein is leveraged to achieve high magnetic-energy density by distributing ....

The dynamic nuclear polarization of hydrogen nuclei by the solid effect in single crystals of samarium doped lanthanum magnesium nitrate (Sm:LMN) has been studied theoretically and experimentally. The equations of evolution governing the dynamic nuclear polarization by the solid effect have been derived in detail using the spin temperature theory and the complete exp....
