Positive and Holistic Couple Relationship Development, the Soul Mates Model, and select Pictograms of Alchemy: A Visual Autoethnography

De La Lama, Luisa 16 September 2015 (has links)
To help contemporary couples successfully navigate the 21st Century’s individualistic, diverse, multicultural, global, postmodern relationship environment, individual, couple, and family counselors, marriage therapists, couple therapists, family psychologists, relationship coaches, marriage educators, counselor educators, and other helping professionals need to understand and promote the positive, strengths-based, holistic, and wellbeing development of couple relationships to help them succeed and flourish in the long- term. This qualitative, narrative, visual autoethnography explores the researcher’s own experience of the culture of her 27-year long soul mate relationship with her partner through the lens of Positive and Holistic Couple Relationship Development Theory (PHRDT), its 7- phase Soul Mates Model, including encounter and dating, commitment, intimacy, building a life, shadow and adversity, renewal, and completion, resulting in the metaphorical development of the philosopher’s stone or gold of the philosophers, and its 12 positive relationship development principles. The study also explores the meanings derived from 8 alchemical pictograms associated with the Soul Mates Model’s 7 phases, which of the 12 positive principles played out in her relationship, and the effectiveness of her and her partner’s deliberate efforts at positive relationship building, as well as how these experiences may inform her teaching and practice. Based on the findings, which include the recall of fourteen years of spiritual, psychic, and visionary encounters with her partner before they met, the researcher concludes that she and her partner are not only soul mates engaged in the soul mating process, but also twin souls, linked together by an unfathomable bond that has helped them develop intimacy, remain bonded through adversity, and flourish as a couple in the long-term. Additionally, the researcher concludes that the Soul Mates Model and 8 alchemical pictograms are useful mythopoeic tools to explore the positive and holistic development of the couple relationship, that all 12 positive principles played out in her relationship, and that the process of soul mating may be taught to others with help of strategic positive, holistic, and mythopoeic interventions, yet that twin- soulship cannot be taught. She thus concludes that soul mates can be grown, yet twin souls must be born.

Ofereceremos, dessa forma, uma contribuição para a compreensão da obra citada, visando dialogarmos sobre os dispositivos da linguagem na configuração do binômio literatura/real. Nesta temática, torna-se necessário perceber a influência da tradição na produção poética contemporânea como forma de revisitação e aprimoramento do sistema de transformação imagético da poesia, bem como compreender como se estrutura e se define o caráter hermético da poesia contemporânea. Tal investigação será feita mediante análise dos poemas que compõem Aleijão na proporção em que utilizaremos referenciais teóricos que visitam desde o embate ontológico, definido por Emmanuel Levinas (2005) e Paul Ricoeur (2008) às referências que tratem dos temas centrais deste trabalho, como: poesia, teoria literária, leitura de imagens, hermetismo e violência. Dessa forma, far-se-ão necessários o arcabouço teórico de Jaime Ginzburg (2012, 2013), Karl-Erik Schollhammer (2012, 2013), bem como Hugo Friedrich (1978), João Alexandre Barbosa (1986), Fábio Andrade (2010), Octavio Paz (2012, 2013). Ao encerrar de nossas discussões, acerca do estudo da imagem de violência, serão utilizadas as contribuições de Gilbert Durand (1988, 2012), Gaston Bachelard (1986), Jean Chevalier e Alain Gheerbrant (2009). Sendo assim, pretendemos mostrar um estudo que permita uma contribuição para a leitura e a seara crítica da obra de Eduardo Sterzi, através do diálogo comparativo entre a literatura e o entorno social que lhes permite a representação. / Looking through the current scenario of poetic production of our literature, influenced by new aesthetic ideologies, bonded to the word that does not exclude the social aspects – although with no extremism – and its disentanglement with the possible inspirational characteristic, we aim to investigate and present how the poetic text, nourished with an ingenious aesthetic work, can present poetic images related to the violence from reading and discussion of the analyzed corpus, Aleijão (2009), by Eduardo Sterzi. We offer, through this matter, a contribution for the comprehension of the cited work, aiming to dialogue about the language devices in the literature/real binomial configuration, on what is related to the current scenario of chaos and renewal of contemporary poetry. Inside this theme, it becomes necessary to perceive the influence of tradition in the contemporary poetry production as a way of revisiting and improving of the imagetic transformation system of poetry, as well as comprehending how to organize and define the hermetic characteristic of contemporary poetry related to this new proposal of the current poetry. Such investigation is made through analysis of poems that are part of Aleijão white proportionally using theoretical references that visit from the ontological debates – defined by Emmanuel Levinas (2005) and Paul Ricoeur (2008) – to the references that talk about the main themes of this paper, like: poetry, literature theory, image reading, hermetics, violence and silence. For these means, it will be necessary the studies of Jaime Ginzburg (2012, 2013), Karl-Erik Schollhammer (2012, 2013), as well as Hugo Friedrich (1978), João Alexandre Barbosa (1986), Fábio Andrade (2010), Octavio Paz (2012, 2013). Concluding our discussions toward the studies of violence images, there will be uses of the contributions by Gilbert Durand (1988, 2012), Gaston Bachelard (2009), Jean Chevalier and Alain Gheerbrant (1986). That said, we intend to present a study that conceive a contribution to the reading and to the aspects of critics for the work of Eduardo Sterzi, through the comparative dialogue between literature and the social surroundings that allows them to have such representation.

Vacuum Brazing of Alumina Ceramic to Titanium Using Pure Gold as Filler Metal for Biomedical Implants

Siddiqui, Mohammad S 08 September 2011 (has links)
One of the many promising applications of metal/ceramic joining is in biomedical implantable devices. This work is focused on vacuum brazing of C.P titanium to 96% alumina ceramic using pure gold as the filler metal. A novel method of brazing is developed where resistance heating of C.P titanium is done inside a thermal evaporator using a Ta heating electrode. The design of electrode is optimized using Ansys resistive heating simulations. The materials chosen in this study are biocompatible and have prior history in implantable devices approved by FDA. This research is part of Boston Retinal implant project to make a biocompatible implantable device (www.bostonretina.org). Pure gold braze has been used in the construction of single terminal feedthrough in low density hermetic packages utilizing a single platinum pin brazed to an alumina or sapphire ceramic donut ( brazed to a titanium case or ferrule for many years in implantable pacemakers. Pure gold (99.99%) brazing of 96% alumina ceramic with CP titanium has been performed and evaluated in this dissertation. Brazing has been done by using electrical resistance heating. The 96% alumina ceramic disk was manufactured by high temperature cofired ceramic (HTCC) processing while the Ti ferrule and gold performs were purchased from outside. Hermetic joints having leak rate of the order of 1.6 X 10-8 atm-cc/ sec on a helium leak detector were measured. Alumina ceramics made by HTCC processing were centreless grounded utilizing 800 grit diamond wheel to provide a smooth surface for sputtering of a thin film of Nb. Since pure alumina demonstrates no adhesion or wetting to gold, an adhesion layer must be used on the alumina surface. Niobium (Nb), Tantalum (Ta) and Tungsten (W) were chosen for evaluation since all are refractory (less dissolution into molten gold), all form stable oxides (necessary for adhesion to alumina) and all are readily thin film deposited as metals. Wetting studies are also performed to determine the wetting angle of pure gold to Ti, Ta, Nb and W substrates. Nano tribological scratch testing of thin film of Nb (which demonstrated the best wetting properties towards gold) on polished 96% alumina ceramic is performed to determine the adhesion strength of thin film to the substrate. The wetting studies also determined the thickness of the intermetallic compounds layers formed between Ti and gold, reaction microstructure and the dissolution of the metal into the molten gold.

INVESTIGATING GERMINATING SEEDS AS OXYGEN SCAVENGERS IN HERMETIC STORAGE: IMPLICATIONS FOR INSECT MORTALITY

Gunakeshari Lamsal (16642938) 01 August 2023 (has links)
<p>Hermetic storage systems have gained global popularity for their ability to minimize stored product losses by depleting oxygen. However, relying solely on insects to deplete oxygen in hermetic storage, when this process takes longer, can result in (further) damage to stored commodities. This study was conducted to investigate: (i) the potential of four different germinating seeds (soybean, rice, cowpea, and corn) in scavenging oxygen within hermetic storage systems; (ii) the impact of container volume and the number of germinating seeds on oxygen depletion; and (iii) the effects of germinating seeds on insect mortality and grain quality. Among the crops tested, cowpea, during their fourth, fifth, and sixth germination stages (T4, T5, and T6), depleted oxygen below 5% within 12 hours. The fourth stage of cowpea (T4) was identified as a potential oxygen scavenger due to its shorter germination time and ease of handling. Moreover, increasing the number of germinating seeds resulted in a faster initial rate of oxygen depletion in all-sized jars. Doubling both the volume of the jars and the number of germinating seeds had a similar rate of oxygen depletion. Additionally, an equation was derived to predict the required number of germinating seeds based on data from different numbers of seed and container volume combinations. Relative humidity levels increased to approximately 90% when empty jars were used but remained consistent at 40% when the jars were filled with grains. Furthermore, using 10, 20, and 30 germinating cowpea seeds with stored grains and insects, oxygen levels were reduced below 5% at different time intervals. Complete adult mortality of <em>C. maculatus</em> was achieved within 3-5 days of exposure, depending upon the number of germinating seeds. 20 and 30 seeds achieved complete mortality within 72 hours, while 10 seeds required 120 hours. As the number of germinating seeds increased, egg counts decreased, and moisture content significantly increased in the treatment involving 30 seeds. Furthermore, no adult emerged after 96 and 120 hours of exposure to normoxia for the 30 and 20 seed treatments, respectively. However, in the 10 seeds treatment, a small percentage of adults (0.29%) did emerge even after 120 hours of exposure.</p>

Design, Fabrication and Testing of Conformal, Localized Wafer-level Packaging for RF MEMS Devices

Collins, Gustina B. 06 December 2006 (has links)
A low-cost, low-temperature packaging concept is proposed for localized sealing and control of the ambient of a device cavity appropriate for Radio-Frequency (RF) Micro- Electro-Mechanical (MEMS) devices, such as resonators and switches. These devices require application specific packaging to facilitate their integration, provide protection from the environment, and control interactions with other circuitry. In order to integrate these devices into standard integrated circuit (IC) process flows and minimize damage due to post-fabrication steps, packaging is performed at the wafer level. In this work Indium and 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 package surrounding a predefined RF microsystem. The bond for the seal is then formed by rapid alloying of Indium and Silver using a temperature greater than that of the melting point of Indium. This ensures that the seal formed can subsequently function at temperatures higher than the melting temperature of pure Indium. This method offers a low-temperature bonding technique with thermal robustness suitable for wafer-level process integration. The ultimate goal is to create a seal in a vacuum environment. In this dissertation, design trade-offs made in wafer-level packaging are explained using thermo-mechanical stress and electrical performance simulations. Prototype passive microwave circuits are packaged using the developed packaging process and the performance of the fabricated circuits before and after packaging is analyzed. The effect of the package on coplanar waveguide structures are characterized by measuring scattering parameters and models are developed as a design tool for wafer-level package integration. The small scale of the localized package is expected to provide greater reliability over conventional full chip packages. / Ph. D.

<b>Accelerating oxygen depletion in hermetic storage using hand warmers to improve pest control</b>

Wenbo Li (19337320) 06 August 2024 (has links)
<p dir="ltr">This study explores the use of hand warmers to enhance hermetic storage. Hand warmers work similarly to conventional oxygen scavengers by consuming oxygen through oxidation. This research aimed to determine how effective hand warmers are in accelerating oxygen reduction and insect mortality in hermetic storage, hence preserving grain quality. The experiments conducted in hermetic containers showed that hand warmers rapidly reduce oxygen levels, achieving insect-lethal conditions much faster than conventional oxygen absorbers like Oxy-Sorb. Our results show that hand warmers brought oxygen levels down to below 5% within 24-48 h and kept them low for an extended period up to 240 h. This quick oxygen depletion led to high insect mortality, reduced oviposition, and inhibited progeny development. Additionally, hand warmers did not negatively impact seed moisture content or germination rates, demonstrating their effectiveness in maintaining grain quality during storage.</p>
