This system is coupled to one extra degree of freedom (extended system) acting as a heat reservoir. In this work, we study the dynamical of the prototype system: the harmonic oscillator thermalized in the Nosé-Hoover dynamics. We observe periodic and quasi periodic regular trajectories in the phase space for different initial conditions. However, the oscillator is non-ergodic and non-canonical in the Nosé-Hoover dynamics, when we add one reservoir degree of freedom (thermostats chain), the momentum distribution tends to the canonical one. The second system studied is an Argonne gas with 4000 particles which interact by means of a Lennard-Jones potential. For this system, we observe phase transitions, momentum distributions in agreement of canonical ensemble, as well, the thermostat efficiency to keep constant the average temperature. / A dinâmica de Nosé-Hoover é determinística e reversível no tempo e realiza uma amostragem estatística de um sistema de muitos corpos no ensemble canônico diretamente a partir da dinâmica do sistema. Esse sistema é acoplado a um grau de liberdade extra (sistema estendido) que desempenha o papel de um reservatório térmico. Neste trabalho, estudamos a dinâmica do sistema protótipo mínimo: o oscilador harmônico na dinâmica de Nosé-Hoover. Observamos trajetórias regulares periódicas e quase periódicas no espaço de fase para diferentes condições iniciais. Embora, o oscilador não seja ergódico e não reproduza as médias do ensemble canônico na dinâmica de Nosé-Hoover, ao adicionarmos mais um grau de liberdade ao reservatório (cadeia de termostatos), a distribuição de momentos tende a canônica. O segundo sistema estudado é um gás de Argônio constituído de 4000 partículas que interagem segundo um potencial de Lennard-Jones. Para esse sistema, observamos transições de fase, distribuições de momento em concordância com o ensemble canônico, assim como a eficiência do termostato de Nosé-Hoover em manter a temperatura média constante.

This is an American Indian ethnographic study for the Hoover Dam Bypass Project. The study sites included three bypass bridge alternatives, each located within one mile from where United States Highway 93 (U.S. 93), at the time of the study, crossed over the top of Hoover Dam at the Arizona-Nevada state line. Due to growth in population and commerce in the Southwest, the roadway at Hoover Dam has experienced a tremendous increase in traffic over the past 30 years, resulting in increased safety hazards to motorists, pedestrians, and the dam itself. Federal, state, and local governments have worked to find a solution to the impacts of increased traffic across Hoover Dam. This project was a continuation of EIS efforts that began in 1989. The goal of this project was to evaluate alternative crossings of the Colorado River near Hoover Dam. The goal of this study was to evaluate the potential impacts to American Indian cultural resources related to the three proposed crossing alternatives. This report is an expanded version of the draft produced in 1998. In 2000, funding became available to carry out further ethnographic research and involve Mohave, Hualapai, and Southern Paiute people.

As part of the American Indian consultation process for the Hoover Dam Bypass Project the Federal Highway Administration (FHWA) consults regularly with representatives of tribal groups that have an interest in cultural and traditional resources affected by the project plans and activities. The focus of this document is on information particular to understanding cultural landscapes and the long standing connections between the Southern Paiutes, Hualapais, and Mohaves and the revered sites of Sugarloaf Mountain and Goldstrike. In the end, these layered intertribal and geographic connections which link these sites met the criteria for establishing the eligibility of Sugarloaf Mountain and Gold Strike Canyon as Traditional Cultural Properties (TCPs). This report was prepared as part of the nomination process. Maps containing locations have been redacted from the public document. Tribal members who want a copy of the un-redacted report please contact Special Collections. Sugarloaf Mountain and Goldstrike Canyon officially were designated TCPs on September 4, 2004.

Má diplomová práce by měla mít ve větší míře analytický charakter. Rozdělila jsem ji na dvě hlavní kapitoly: hospodářský vývoj USA ve 20. letech 20. století a pokusy o obnovu bankovního systému. V první kapitole se věnuji analýze situace, v jaké se Spojené státy nacházely ve dvacátých letech, kdy můžeme pozorovat známky nastupující recese. Spojené státy změnily své postavení a staly se světovou mocností a hlavním vítězem první světové války. Hospodářskou politiku výrazně ovlivňovala válečná zkušenost tohoto konfliktu. S tím však přicházely i nové hospodářské, sociální a politické důsledky. Ze světového dlužníka se staly světovým věřitelem. Narůstala investiční aktivita, lidé si zvykli žít svůj ,,život na půjčku? a stále více se zadlužovali. Měnila se také politická situace, kde vládu demokratů vyměnila na dlouhé období vláda republikánů. V hospodářské politice to znamenalo zejména nižší daně, vyšší cla, omezení přímé regulace a decentralizace rozhodování. Rozpočtová politika se přizpůsobila zejména splácení válečných půjček, což znamenalo po celé období dvacátých let přebytkové rozpočty.

This presentation was prepared for a conference focusing on risk assessment and facility siting issues in Sweden in 2001. This talk presents key findings from the Hoover Dam Ethnographic Studies.
