Confronto di solutori FEM e solutori BEM per lo sloshing in contenitori

Ė stato studiato il fenomeno di sloshing attraverso due diversi algoritmi numerici: il primo consiste in una discretizzazione con elementi finiti dell’equazione di Navier Stokes in formulazione Arbitrary Lagrangian Eulerian, è indicato nel seguito come FEM ed è descritto in [3]; il secondo è basato sulla discretizzazione delle equazioni agli integrali di contorno e delle equazioni di evoluzione della superficie libera ed è indicato come BEM e descritto in [2]. Per verificare la validità dei due codici sono stati confrontati i loro risultati con quelli presenti in letteratura, sia derivanti da altri codici numerici, sia ottenuti come risultati sperimentali. Il confronto è stato effettuato per un’ampia gamma di situazioni, in modo da studiare il comportamento dei due codici al variare delle caratteristiche della sollecitazione e delle dimensioni del dominio

The Relationship Between the Teachers\u27 Instructional Repertoire and the Students\u27 Perceptions of the Teachers Meeting Their Educational Needs

A portion of a recent radio and television commercial produced for the Nebraska State Education Association states that, Teaching is to touch a life forever. Practically everyone who has been involved in the educational process as a student can reflect upon particular teachers who have made some impression upon them. Whether that impression can be positive or negative, the fact remains that the student\u27s life was indeed touched forever by the teacher. Since the teacher plays such a vital role in the educational life of a student it would be interesting to see what research reports about teaching skills as they relate to student performance

Shock wave interaction with a toroidal air plasma

The University of Missouri--Columbia has recently developed an experimental test stand for the purposes of studying the interaction of shock waves with plasmas in ambient air. An exploding-wire-triggered shock tube is used to produce the shock wave for interaction with plasma in air. For the plasma source, an exploding wire discharge has been confined in a cylindrical geometry to form a freely propagating toroid-shaped plasma. The initial plasma is formed by discharging a 11 [micro]F, 4.4 kJ capacitor bank through a thin wire. This discharge is then forced to expand toward a secondary discharge region which further heats and energizes the plasma. The confining geometry coupled with the secondary heating produces a multi-millisecond duration toroidal air plasma, or TAP. The TAP has a sufficient duration to observe its interaction with the incoming shock wave. Pressure sensors, high speed photography, Schlieren imagery, emission spectroscopy, as well as current and voltage probes have been configured as a full diagnostic suite to observe the interaction of the shock wave and the TAP discharge. The novel TAP discharge is characterized and explored and the experiments within provide qualitative and quantitative results on the effects of interacting a shock wave with a plasma in ambient air.Includes bibliographical references

Controls of bedrock properties, climate, and biota on hillslope and fluvial denudation in the Coastal Cordillera of Chile

This thesis describes the effects of bedrock properties, climate, and biota on erosion, weathering, and landscape morphology along the Coastal Cordillera of Chile. Field sites sit along a climate and vegetation gradient, and include a semi-arid, mediterranean, and humid site, all underlain by granitoid lithology. In situ 10Be cosmogenic radionuclide analysis was used to measure erosion and weathering rates of bedrock, boulders, soils, and stream sediment in each field site, and topographic analysis tools (Topotoolbox in MATLAB) were used to quantify topographic metrics such as slope and drainage density. Field surveys were additionally conducted, including sediment and boulder grain size distributions, and bedrock geochemistry and mineralogy. The first study focuses on the effects of bedrock fractures and immobile boulders on differential denudation rates within in each field site. Results from cosmogenic radionuclide analysis and field measurements indicate that unfractured bedrock and large hillslope boulders erode more slowly than the surrounding soil, and form topographic highs. The second study focuses on boulders in streams, and results from cosmogenic radionuclide analysis indicate that boulders in more humid climates are more easily transported and therefore have shorter residence times in streams. The third study focuses on lithological controls on landscape morphology, and results imply that subtle differences in granitoid lithology can set drainage density through differences in infiltration and erodibility.Diese Doktorarbeit beschreibt die Auswirkungen von Grundgesteinseigenschaften, Klima und Biota auf Erosion, Verwitterung und Landschaftsmorphologie entlang der Küstenkordillere Chiles. Feldstandorte liegen entlang eines Klima- und Vegetationsgradienten, einschließlich halbtrockener, mediterraner und feuchter Standorte, die alle von Granitoidlithologie unterlegt sind. Zur Messung der Erosions- und Verwitterungsraten von Grundgestein, Felsbrocken, Böden und Bachsedimenten an jedem Feldstandort wurde eine In-situ-10Be-Analyse kosmogener Radionuklide verwendet. Darüber hinaus wurden topografische Analysetools (Topotoolbox in MATLAB) zur Quantifizierung topografischer Metriken wie Neigung und Entwässerungsdichte verwendet . Darüber hinaus wurden Felduntersuchungen durchgeführt, einschließlich der Korngrößenverteilung von Sedimenten und Geröll sowie der Geochemie und Mineralogie des Grundgesteins. Die erste Studie konzentriert sich auf die Auswirkungen von Grundgesteinsbrüchen und unbeweglichen Felsbrocken auf die unterschiedlichen Entblößungsraten innerhalb der einzelnen Feldstandorte. Ergebnisse der Analyse kosmogener Radionuklide und Feldmessungen deuten darauf hin, dass ungebrochenes Grundgestein und große Felsbrocken an Hügeln langsamer erodieren als der umgebende Boden und topografische Höhen bilden. Die zweite Studie konzentriert sich auf Felsbrocken in Flüssen, und Ergebnisse der kosmogenen Radionuklidanalyse deuten darauf hin, dass Felsbrocken in feuchteren Klimazonen leichter transportiert werden können und daher kürzere Verweilzeiten in Flüssen haben. Die dritte Studie konzentriert sich auf lithologische Kontrollen der Landschaftsmorphologie, und die Ergebnisse deuten darauf hin, dass subtile Unterschiede in der Granitoidlithologie die Entwässerungsdichte durch Unterschiede in der Infiltration und Erodierbarkeit beeinflussen können

Social media campaign and food waste challenge raises awareness and reduces food waste in the home

It is estimated that nearly 40% of the food produced in America is wasted. Households comprise the largest contributor to this total food waste, with retail and food service coming in a close second. The goal of this study was to explore awareness about the issue of food waste in an effort to reduce food waste in the home. A social media campaign and 30-day challenge was developed. A pre- and post-survey was developed and administered to observe the attitudes and awareness of the issue of food waste. There was 1167 pre-survey responses, 17 post-survey responses, and 15 individuals participated in the 30-day challenge. There was a slight decrease in preventable food waste observed when comparing baseline to challenge weeks. Overall most participants believed the social media posts were informative and reported they learned strategies they can use to reduce food waste. Further research and education is needed to teach mindful shopping, storage, and cooking techniques to minimize food waste in the home. Due to the magnitude of the food waste issue in the U.S., there is a need for dietitians and other food and nutrition professionals to educate others, implement food waste reduction strategies in their place of work, and advocate for policy change that limits food waste from farm to landfill

“The Tremendous Products of a Son of the Gods.” Missa solemnis (Op. 123), Overture (Op. 124), and Ninth Symphony (Op. 125)

The premiere of Beethoven’s Ninth Symphony at the Kärntnertortheater in Vienna on May 7, 1824, is generally considered a milestone in music history. This article argues against the common characterization that Beethoven, in this, his (last) academy, programmed a monumental symphony and, perhaps with some embarrassment, a few filler pieces, but instead very consciously chose to highlight his three most recently composed orchestral works: the overture to the festival play Die Weihe des Hauses op. 124; Kyrie, Credo and Agnus Dei of the Missa solemnis op. 123; and the Ninth Symphony op. 125. Listening to these three works together opens up interesting perspectives on the expressive potential of Beethoven’s late orchestral works: despite the different occasions of composition and genre conventions, Beethoven implemented similar aesthetic ideas in them which manifest themselves, among other things, in numerous fugues, similar symbolic motifs, and interpolated war reminiscences

Working Forest Conservation Easement Our Forests today and for the Future

Abstract A Working Forest Conservation Easement is an efficient and effective present-day approach to solving the problem of dwindling quantities of reasonably unspoiled land in America.  The United States of America, from the time of the signing of the Declaration of Independence, allowed and encouraged private ownership of land.  As population increased, demand for agricultural products increased.  As science and technology advanced, so did our ability to fully extract and deplete natural resources from the land.  Historically, landowners used their land as they saw fit, with little concern for the long-term consequences.  Public and private conservation groups today continue to recognize that without change in attitude, increased incentives, and specific laws that regulate land use, America will eventually consume and ruin the land.Purchase College SUNYEnvironmental StudiesBachelor of ArtsTaylor, Ryan W
