Quantitative Beurteilung des Gaseintrages in thermische Energieversorgungssysteme aufgrund der GaspermeationSittiho, Mutchima 11 October 2011 (has links) (PDF)
Bei einem thermischen Energieversorgungssystem, insbesondere einer Warmwasserheizungsanlage, spielen die in Wärmeträgermedium (Wasser) gelösten Gase (Sauerstoff und Stickstoff) für einen einwandfreien Betreib eine große Rolle, weil einerseits der im Wasser gelöste Sauerstoff zu einer Korrosionsreaktion an metallischen Anlagenbauteilen führt, was wiederum eine Reihe von negativen Konsequenzen, wie Verschleiß der Bauteile, Verstopfung der Rohrleitungen oder Durchrostung, hat. Andererseits kann der im Wasser gelöste Stickstoff aufgrund seiner reaktionsträgen Eigenschaft zu einer Gasblasenbildung führen, die wiederum eine Zirkulationsstörung im Wasserkreislauf bzw. eine Beeinträchtigung der Wärmeversorgung der Heizkörper bewirkt. Die Folgen dieser Systemstörungen sind hohe Wartungs- und Reparaturkosten sowie Reklamationen bei Planern, Anlagenherstellern und Kunden. Erkennt man die Ursachen für das Vorhandensein der Gase in der Heizungsanlage, so können Gegenmaßnahmen rechtzeitig ergriffen werden. Dadurch kann das Problem zum Teil behoben oder zumindest das Schadensausmaß begrenzt werden. Ziel dieser Arbeit ist es, das Gasproblem aufgrund der Gaspermeation in Heizungsanlagen quantitativ zu beurteilen und anschließend anhand der daraus gewonnenen Erkenntnisse mögliche Lösungsansätze zur Reduzierung bzw. Beseitigung des Gasproblems vorzuschlagen.

Desenvolvimento de novos compósitos destinado a materiais de construção civil, com base em resíduos industriais de solo de decapagem, lodo e sedimentos de dragagem do porto de Antonina e cal virgem comumPan, Roberto Chun Yan 09 June 2015 (has links)
Pesquisa realizada para analisar o compósito de solo de decapagem (SD) considerado resíduos nas jazidas de minérios, em especial de calcário do município de Almirante Tamandaré, da Região Metropolitana de Curitiba neste trabalho, juntamente com o lodo e sedimentos de dragagem marinha do Porto de Antonina, no Estado do Paraná, e o uso cal virgem comum, como aglomerante pertencente à região de Almirante Tamandaré. Foram utilizados vários teores dos materiais para a determinação de 12 (doze) compósitos. Para o solo de decapagem os teores variaram entre 30% a 60%, para o material de dragagem os teores variaram entre 20% a 50% e o teor de aglomerante de cal virgem comum variou entre 15% a 30%. Foram moldadas idades de cura de 3 dias, 7, 14, 28, 60, 90, 180 e 365 dias. O aumento da resistência à compressão durante a cura foi proveniente das reações químicas das partículas sólidas das matérias-primas em ambiente alcalino gerando novas formações amorfas. Também foram analisados os materiais nos métodos de MEV com EDS, DRX e FRX, para a obtenção da composição química e formação estrutural dos novos compósitos. Todos os resultados da resistência à compressão uniaxial, com 28 dias de cura ao meio ambiente das 12 (doze) composições, obtiveram resultados médios de 7,7 MPa, atendendo satisfatoriamente a norma NBR 7170:1983 que determina a resistência à compressão igual ou acima de 4,0 MPa, destinada à produção de materiais de construção para alvenaria de vedação, sem fins estruturais. Comprovando o uso desses compósitos em materiais de construção civil, principalmente para os segmentos de blocos ou tijolos de vedações, sem fins estruturais, sem a necessidade de cozimento ou empreendimento de energia calorífica para a cura das peças, contribuindo para o meio ambiente e a sustentabilidade ambiental. / Research conducted to analyze the composite with pickling soil (SD), considered waste in mineral deposits, especially of limestone in the city of Almirante Tamandaré, the Metropolitan Region of Curitiba in this work, along with the sludge and marine dredging sediment from the Port of Antonina, State of Paraná, and use the common quicklime as binder belonging to the same region of Almirante Tamandaré. Various amounts of materials were used for the determination of twelve (12) composites. For the stripping soil content ranged from 30% and 60%, for the dredging material contents ranged from 20% and 50% and binder common quicklime content ranged from 15% to 30%. Were molded curing ages of 3 days, 7, 14, 28, 60, 90, 180 and 365 days. The increase in compressive strength during curing was derived from the chemical reactions of solid particles of raw materials in alkaline environment generating the new amorphous formations. Also the raw materials were analyzed in the SEM with EDS method, DRX and FRX, to obtain the chemical composition and formation structures of the new composite. All results of the uniaxial compressive strength, with 28 days of curing the environment of the twelve (12) compositions, obtained average results of 7.7 MPa, satisfactorily meeting the NBR 7170:1983 standard that determines the resistance to compression equal or above 4.0 MPa, for the production of building materials for sealing masonry without structural purposes. Proving the use of these composites in construction materials, especially for thread block or brick fences without structural purposes, without the need for cooking or heating energy project for the healing of parts, contributing to the environment and sustainability Environmental.

Doctrine and Covenants Section 110: From Vision to CanonizationAnderson, Trever 07 July 2010 (has links)
This thesis answers the question of how a vision recorded in Joseph Smith's journal found its home in the Doctrine and Covenants and become recognized as canonized scripture. The April 3, 1836, journal entry became known as Section 110. Section 110 serves as a foundation for the current practices and doctrines of The Church of Jesus Christ of Latter-day Saints, involving temple building and temple ordinances. Thus it is important to understand the history of this Section from journal entry to canonization because it is an example of recovering revelation. This thesis also explores contributing factors that could have led to the rediscovery of the 1836 vision. While Joseph Smith and Oliver Cowdery were in the Kirtland Temple with veils drawn around them at the Melchizedek Priesthood pulpits on April 3, 1836, they both saw Jesus Christ, Moses, Elias, and Elijah. Jesus Christ accepted the newly built temple and Moses, Elias, and Elijah committed keys to Joseph Smith and Oliver Cowdery. The vision was recorded, but as of yet, there is no evidence that the vision was publicly taught by Joseph Smith nor by Oliver Cowdery. This thesis follows the pattern established by Section 110 and the reclamation of the revelation and looks at how this section paved the way for other revelations and visions to move from handwritten pages to doctrinal levels of canonization, such as Sections 137 and 138. Joseph Smith had the vision recorded in his journal by Warren Cowdery, who served as a scribe to him. Joseph Smith also had the journal entry written in the Manuscript History of the Church. Although Joseph Smith did not publically declare that the 1836 vision had occurred to him and Oliver Cowdery, he still taught about the visitors in the vision and of their importance. After Joseph Smith's death, the leaders of the Church had his history printed in Church owned newspapers. The first time the vision was published in print was on November 6, 1852, in Salt Lake City, Utah, in the Deseret News. Outside influences of the late 1850s through the 1860s put pressure on the Church. Some of these potentially destructive influences were the Utah War, Civil War, transcontinental railroad, Spiritualism movement, and the lack of understanding of the foundational doctrines of the Church by the rising generation that had been a part of the Church from its beginnings with Joseph Smith as its Prophet. This thesis explores these potentially destructive forces on the Church and its doctrine, and looks at how the leadership of the Church responded to them and how their response influenced the canonization of the 1836 vision. Under the direction of Brigham Young, Orson Pratt oversaw the publication of the new 1876 edition of the Doctrine and Covenants. This new edition contained twenty-six new sections, including Section 110. After the death of Brigham Young in 1877, John Taylor sat at the head of the Church as president of the Quorum of the Twelve Apostles. While Orson Pratt was in England, preparing to print a new edition of the Book of Mormon on electrotype plates, he asked John Taylor about printing the Doctrine and Covenants with the electrotype plates as well. John Taylor agreed on condition that Orson Pratt add cross references and explanatory notes, as he had done with the Book of Mormon. Using the 1876 edition, Orson Pratt made the requested additions and the new edition of the Doctrine and Covenants was printed in 1880 and canonized on October 10, 1880, in a General Conference of The Church of Jesus Christ of Latter-day Saints, where all present voted unanimously to accept the 1880 edition as canonized scripture.

Vývoj injektážních směsí pro dodatečné těsnění sypaných hrází / The development of grouting for additional sealing of embankment damsMichalčíková, Magdaléna January 2015 (has links)
Seal of sand or gravel by chemical injection is known and used for a long time. Chemical grouting are however expensive and sometimes the use of cement does not lead to desire effects. So it is trying to find new materials and methodologies injection arrangement works. To achieve savings of chemical products are added to a mixture clay and cement. Clay-cement grouting mix are used not only in order that they are better quality, but also because in this way proposed mixtures have a tendency to penetrate better into incoherent sediments that need additional sealant of chemical injection. For further possible reductions of economic terms the mixture is trying to replace the classic clay. As a suitable substitute for classic clay is to a certain extent the use of secondary raw materials. Above all it is fly ash. As a part of my thesis I deal with the appropriateness use of these materials and examining their properties in the mixture. It was found that by using fly ash were improving consistency of the fresh mixture, reducing the amount of water-cement ratio and reduce shrinkage of the mixture. On the other hand, by using fly ash has been increasing decantation, permeability atc. In the next stage of my work was examined the influence of the quality of cement, lime and liquefaction in the mixture. The aim of thesis is to propose the optimal injection mixture for additional sealing earth dams.

Flächennutzungsmonitoring - aktuelle Ergebnisse und Entwicklungen im IÖR-MonitorMeinel, Gotthard, Krüger, Tobias, Schumacher, Ulrich, Hennersdorf, Jörg, Förster, Jochen, Köhler, Christiane, Walz, Ulrich, Stein, Christian January 2013 (has links)
Nach Darstellung der Anforderungen an ein zeitgemäßes Flächennutzungsmonitoring werden aktuelle Ergebnisse des Monitors der Siedlungs- und Freiraumentwicklung (IÖR-Monitor) vorgestellt. Diese beruhen insbesondere auf der Analyse topographischen Geobasisdaten von 2012 (mittlere Grundaktualität 2010). Die Siedlungs- und Verkehrsfläche steigt danach weiter ungemindert, sodass keine Entwarnung bzgl. des Erreichens der Flächensparziele gegeben werden kann. Da sich der IÖR-Monitor insbesondere auf die Auswertung des ATKIS Basis-DLM stützt, werden dessen jüngste Entwicklungen mit den Aspekten Aktualität und AAA-Migration vorgestellt. Erstmals werden die Ergebnisse des IÖR-Monitors durch Migrationseffekte geringfügig beeinflusst, die im Detail dargestellt werden. Anschließend werden neue Indikatoren der Kategorie Siedlung (Bodenversiegelungsgrad), Gebäude (Gebäudedichte und -überbauungsgrad) sowie Landschaftsqualität (Anteil naturbetonter Flächen und Hemerobieindex) erläutert. Inzwischen ist auch die kleinräumige Indikatordarstellung in Form von Rasterkarten bis 100-m-Rasterweite in einem integrierten Detailviewer mit GIS-Funktionalität möglich. Die technische Realisierung und die verfügbaren Indikatorkarten werden kurz vorgestellt. Der Beitrag schließt mit einem Ausblick auf die nächsten Arbeiten im IÖR-Monitor ab.
