Dynamics of vacuum-sealed, double-leaf partitions
… and potential effectiveness of using vacuum-sealed, double-leaf partitions for applications in noise control. Substantial work has been done previously on double-leaf partitions where the acoustics of the inner chamber and mechanical vibrations of structural supports are passively and …

Adversarial risk analysis for first-price sealed-bid auctions
First-price sealed-bid (FPSB) auctions have mostly been modelled in auction theory using the decision-theoretic and Bayesian game-theoretic approaches. From a practical point of view, each approach has its limitations. To overcome those limitations, Rios Insua et al. (2009) introduced an approach, …

The structural mechanics behavior of sealed insulating glass units
Aesthetically pleasing, glass sheathed buildings and insulating glass (IG) units have formed a combination that is at once attractive and efficient. The use of IG units has increased in all types of buildings construction. Typical IG units consist of two glass plates separated by a perimeter spacer …

Hermetically sealed encasements for historic document display and preservation
The goal of this thesis was to develop designs and methods for the preservation and display of historic documents. The results were applied via the design, manufacture, and installation of five hermetic display encasements for the original Massachusetts Constitution (1780), a Goddard broadside of …

Sorption and leaching of glyphosate on partly sealed urban areas
Anlass für die Untersuchungen war der Einsatz des Herbizids Glyphosat zur Unkrautbekämpfung auf Gehwegen. Da das für den Gehwegbau eingesetzte Material, geringere Sorptionskapazitäten für Glyphosat als landwirtschaftliche Böden aufweist, war das Ziel dieser Arbeit abzuschätzen, ob nach Applikation …

Buoyancy-thermocapillary convection of volatile fluids in confined and sealed geometries
… change, such cooling devices usually employ a sealed cavity from which almost all noncondensable gases, such as air, have been evacuated. Heating one end of the cavity, and cooling the other, establishes a horizontal temperature gradient that drives the flow of the coolant. Although such flows …

Model for a Shale Gas Formation with Salt-Sealed Natural Fractures
… This study suggests that dissolution of salt-sealed natural fractures in the shale offers a novel explanation for the early boundary dominated flow. We first discuss a plausible diagenetic history for generation of a salt-sealed natural fracture system in shale gas and how core, log, and …

The Background and Meaning of the Sealed Book of Revelation 5
… study was to determine the background of the sealed βιβλίον of Rev 5 and its meaning and significance in its literary context.</p> <p>The historical survey shows that the interpretation of the sealed βιβλίον has undergone significant modifications in the course of time. The earliest documented …

Closure integrity testing of heat sealed aseptic packaging using scanning acoustic microscopy
… online evaluation of the integrity of heat sealed, flexible package structure commonly used in packaging of aseptic and shelf-stable food products. A scanning acoustic microscope (SAM), Olympus UH-3, and image analysis system were used to establish the operational parameters to …

Polyurethane Sealant to Mitigate Crack Effects in Glass-to-Metal Sealed Underwater Connectors
Glass insulated underwater connectors allow for deep sea exploration. However, the long term reliability of the insulation is reduced due to surface cracks formed during manufacturing. In this thesis, we propose and test a sealant to overcome limitations associated with internal cracks. The need …

The design, construction and testing of a hermetically sealed breast platfrom for dual-modality mammography
When ultrasound is used as an adjunct to X-ray mammography in either hand-held or automated mode, the patient typically lies in a prone position. The disadvantages of this approach include: variable image quality; poor co-registration of X-ray and ultrasound images; and increased costs and patient …

Design of a hermetically sealed MEMS resonator with electrostatic actuation and capacitive third harmonic sensing
… into the fabrication to create a hermetically sealed device that can easily be incorporated into other MEMS designs. Most resonators operate in vacuum because air damping at higher pressures greatly decreases both resonant frequency and quality factor. This loss is directly related to the …

A Garden Locked, A Fountain Sealed: Female Virginity as a Model for Holiness in the Fourth Century
<p>Despite centuries of Christian theologians and lay Christians alike assigning and/or accepting an entrenched misogyny in the writings of Ambrose, Jerome, and Augustine, close examination of their work on its own terms and in its own time reveals that, in fact, they did not hold women in lesser …
