Second Skin : an antithesis to hermetic architecture
… with air, water, and heat in a world post hermetic seals. Rather than simply protecting us in another mini bubble, they function as a layer of mediation between us and our environment.

Sustainable design of hydrocarbon refrigerants applied to the hermetic compressor
International environmental concern led to the control and phase out of traditional chlorofluorocarbon refrigerants (CFCs) under the terms of the Montreal protocol. CFCs used in domestic applications were initially replaced with hydrofluorocarbons (HFCs) such as R134a which has a zero ozone …

Dynamic finite element modeling and analysis of a hermetic reciprocating compressor
… efforts were made to accurately represent the hermetic shell which presents several inherent modeling difficulties due to its geometry and other characteristics which result from a deep drawn manufacturing process. The importance of physical simplifications such as geometry representation, …

Hermetic heresies: a sculptural revision of the iconography of the classical muse
Concentrating on the object as vestige of function in the portrayal of muses in ancient Greek sculpture, my aim is to dismiss their traditional representations, and to reconstruct the choir of the muses by iconographic substitution. The hypothesis is that if the muses are prototypes rather than …

Color and Consciousness: Research and Painted Process of Inundate, Intumesce, Hermetic, and Luminiferous
… of the two phenomena. With Inundate, Intumesce, Hermetic, and Luminiferous, I aimed to supplant written language with visual language in this co-dependent relationship by creating hyper-saturated, figurative paintings that allow for the viewer to expand their self-consciousness alongside their …

The Path to Personal Salvation: The Hermetic Trope of Self-Mastery in Shakespeare, Bacon, and Milton
… examines Renaissance authors investment in the Hermetic tradition. This tradition is based on the Hellenistic Egyptian philosophical-theological writings ascribed to Hermes Trismegistus, which emerged in parallel with early Christianity, Neoplatonism, and Gnosticism. The Hermetic tradition …

Identification of sound transmission paths within a hermetic reciprocating refrigeration compressor via multiple-input/single-output modeling
Through the use of multiple-input/single-output (MISO) modeling, the propagation paths of sound within a reciprocating refrigeration compressor have been investigated and ranked. By investigating the nature of sound propagation within reciprocating compressors, it is hoped that compressor …

Effects of Storage Conditions of Aspergillus Growth and Aflatoxin Production in Peanuts. A Study in Ghana
… aim was to determine the impact of the switch to hermetic storage on peanut farming and marketing profitability in Ghana. Different peanut treatments, with and without Aspergillus flavus fungi, were packaged in different systems; specifically, polypropylene woven sacks and hermetic packaging. …

Sustainable development of refrigerator systems using replacement environmentally acceptable refrigerants
… in the electrical power drawn by a reciprocating hermetic compressor, was used under different experimental conditions. Furthermore, a detailed life cycle assessment on a domestic refrigerator was performed to help quantify the ensuing environmental burdens. In this way, a relation between …

Hermetically sealed encasements for historic document display and preservation
… design, manufacture, and installation of five hermetic display encasements for the original Massachusetts Constitution (1780), a Goddard broadside of the Declaration of Independence (1777), an original copy of the Bill of Rights (1789), the 1629 Charter of Massachusetts Bay, and the 1692 …

Design, Fabrication and Testing of Conformal, Localized Wafer-level Packaging for RF MEMS Devices
… Silver are used to seal a monolithic localized hermetic pack- age. The cavity protecting the device is formed using standard lithography-based processing techniques. Metal walls are built up from the substrate and encapsulated by a glass or silicon lid to create a monolithic micro-hermetic …

Mechanical design and analysis of implantable components for a retinal prosthesis
… Chronic testing of a working prosthesis requires hermetic encapsulation of all implanted electronics; any direct contact with the fluid in the eye will damage the circuitry and render the device ineffectual. A metal housing, which has provided effective protection of other prostheses, would …

Three essays in experimental and behavioral economics of technology adoption in India
… countries. I study the impact of on-farm hermetic storage technology on four dimensions of food security availability, access, utilization and stability. Postharvest losses during storage manifest in reduced quantity of food available to households and reduced quality of stored grain, …

Ishmael: The Dissolution of a Romantic and the Emergence of a Poet.
… beginningsùthe womb of the mother. Through his hermetic voyage into nature and back to the unconscious, he is able to reconnect to his origins. No longer is he the alienated wanderer, but recreated as the artist, able to create his own myth and identity.</p>

Fault detection methods for vapor-compression air conditioners using electrical measurements
… electrical and mechanical measurements on a semi-hermetic compressor. The final diagnostic method detects refrigerant leakage in a residential air conditioning system by identifying changes in the system's cycling behavior. This method also uses measurements of the compressor's electrical power, …

Manufacturing and characterization of welded, sintered condensers for a loop heat pipe
… and a welded flange design for the creation of a hermetic seal, resulted in a more reliable condenser, which functioned in a similar manner to previous designs. Additionally, the performance of the condenser under air restriction was addressed.

Western esoterism : Ultimate Sacred Postulates and Ritual Fields
… matrices. This branch of esoterism, rooted in a Hermetic milieu, is labelled dialectical esoterism because of the dialectical relationship between the ‘lower’ (man, earth) and the ‘higher’ (heaven, the divine, God). These five matrices are: I: Purpose (pronoia), rather than karma or sin. II: The …
