Manufactura y desarrollo de nonogeneradores piezoeléctricos de óxido de zinc
No full textEn esta investigación se fabricaron recubrimientos micro y nanoestructurados de óxido de zinc a partir de pintura en aerosol anticorrosiva o galvanizado en frio con un 93% zinc, aplicado en sustratos de aluminio, vidrio y acero para luego ser tratados con diferentes métodos de síntesis basados en oxidación a alta temperatura. La caracterización de la microestructura se realizó mediante microscopía electrónica de barrido (SEM), microscopía de fuerza atómica (AFM) y difracción de rayos X (XRD). Además, se evaluó el material como nanogenerador piezoeléctrico mediante un circuito de amplificación de voltaje medido através de un osciloscopio. La microscopía confirmó la generación de nanoalambres en la síntesis desarrollada con el uso de un horno, el análisis por XRD confirmó la formación de óxido de zinc y las pruebas con osciloscopio demostraron la funcionalidad piezoeléctrica.Ingeniero Mecatrónicopregrad

Efecto de las adiciones de polvos de acería (eafd) en las propiedades de concretos asfálticos
No full textRESUMEN: El polvo de acería o polvo de horno de arco eléctrico (EAF dust) es un desecho peligroso disponible en millones de toneladas generados por la industria metalúrgica en todo el mundo. El principal objetivo de esta investigación es evaluar este desecho en mezclas con asfalto. Se evaluó la microestructura y la distribución de partícula por microscopia óptica y microscopia electrónica de barrido (SEM). Los resultados muestran una buena distribución de los polvos en la matriz de asfalto. La mayoría de los ensayos mecánicos muestran un ascenso en las propiedades mecánicas del asfalto (punto de ablandamiento, penetración y viscosidad) hasta la mezcla de 10%, luego ocurre un descenso de las propiedades mecánicas, lo que se puede explicar por la interacción entre el asfalto y el desecho usado.MaestríaMagíster en Ingenierí

Henry McPherson land grant paperwork
No full textA variety of records regarding James and Henry McPherson's land grants within the Seneca reservation as provided in the treaties of St. Mary's and Lewistown. The documents include an affidavit from James McPherson in which he chooses a section of land as laid out the 1817 Treaty of St. Mary's. The second image is a plat of the area showing James and Henry McPherson's land claims. In regards to Henry McPherson's claim of a full section of 640 acres, the documents include a copy of deed from the Seneca Nation for a half-section of land, and a draft of a letter from Henry McPherson to General Joseph Vance in support of his claim to a full section. It appears that these white men were granted land within the area reserved to the Seneca by the Treaty of St. Mary's and the Treaty of Lewistown. Apparently, the tribe granted them land in recognition of their friendship for, and service to, the Seneca
Yellowstone National Park: through the lens of time

Henry Adams, Jr. letter to father, February 5, 1952
No full textThis letter was written by Henry Adams Jr. to his father, Henry Adams, expressing his feelings and experiences during his time in the army. Junior, as he was called in the family, had been posted to Alaska after his basic Army training, and assigned to an otherwise all-white company.
In this three-page letter written on decorative notepaper, Junior writes about his army experiences, and says that he feels like Jackie Robinson, a test case for integrated units in the military. The United States Army was not integrated during World War II; African Americans and whites served in separate units. Harry Truman issued an executive order intended to end segregation in the Army in January of 1948, and letters such as this indicate that the executive order took some time to become fully effective
View of Henry Mountains from the White Canyon Processing Plant, Utah

The Vanadium Corporation of America's White Canyon Processing Plant was located in Hite, Utah. This plant was built in 1949 by the Vanadium Corporation of America under contract with the US Atomic Energy Commission to process copper-uranium ores from nearby mines. The small mill operated as a pilot plant to supply uranium concentrate to the AEC until it was shut down in 1953. The mill was dismantled in about 1954. The site was inundated by the formation of Lake Powell in 1965 after an impact study was done and some high-grade tailings were removed from the mill site.Sponsored by the Colorado State Library, the regional library systems of Colorado, and the Institute of Museum and Library Services
