Osbornellus emmeni Dominguez & Godoy 2010, sp. nov.
No full textOsbornellus emmeni Domínguez & Godoy, sp. nov. (Figs. 21a–21e) Description. Length: 5.7 mm. Member of the O. auronitens group (Fig. 1a). General description as in O. eberhardi. Male genitalia: Pygofer less than twice as long as width, moderately projected posteriorly, narrow and rounded at apex; with very long macrosetae dispersed along apical half (Fig. 21a). Valve triangular. Plates very long, rounded at apex and with filamentous setae (Fig. 21b). Style with apophysis short and truncate (Fig. 21c). Aedeagus in ventral view wide basally, then slightly narrowed; shaft with apex truncate and slightly shorter than ventral processes (Fig. 21d). Ventral processes arising at one-third the length of the aedeagus, separated distally, tapered, apices sharp. Shaft in lateral view curved dorsad; dorsal projection short and truncate. Gonopore apical. Ventral processes curved dorsad, tapered, apex sharp, separated distally from shaft (Fig. 21e). Diagnosis. Very similar in appearance to O. barletti, but in ventral view the aedeagal shaft and ventral processes of O. emmeni are slightly curved dorsad. In O. barletti they are more curved, especially the shaft. Distribution. Known only from Costa Rica; 2050 m. Etymology. This species is named in honor of Daniel Emmen in recognition of his loan of specimens and providing laboratory facilities for the first author.

Report on Meteorological Research March 1, 1935 (m-1)
No full textThe object of the report was to elucidate in detail the various features of the research program in meteorology being carried on at the Daniel Guggenheim Airship Institute in Akron, Ohio. Mr. L. J. Fangman, of the U.S. Weather Bureau, was collaborating with the author in carrying out work such as a study of autographic records of the various meteorological elements during frontal passages with a view to the possible prediction of the intensity of the accompanying disturbance as it may affect the operation of aircraft and a study of atmospheric gustiness with a view to finding the dependence between frequency end amplitude of velocity fluctuations and the vertical temperature and velocity gradients
(Fourth) Report on Meteorological Activities at the DGAI (8-1-36)(Weather Bureau Copy)
No full textThis report is on the investigations of frontal phenomena at the Daniel Guggenheim Airship Institute in Akron, Ohio from January 1, 1935 through August 1, 1936. The investigation was carried out with the cooperation of the U.S. Bureau of Aeronautics, the U.S. Weather Bureau, the California Institute of Technology, and the Guggenheim Airship Institute. Mr. R.C. Robinson of the Weather Bureau cooperated with the author in carrying out the investigation. The object of the investigation was to determine the intensity of the atmospheric disturbances (i.e. rapidity of wind shift and gustiness) accompanying the passage of cold fronts, along with a study of the characteristics of the air masses involved and other features which might affect the intensity of the disturbance. The report treated thirty cold fronts which passed the station during 1935 to 1936
Emisiones de metano de novillos en fase de terminación alimentados bajo dietas con diferentes de fibra
No full textEl cambio climático es una problemática mundial, en el cual el metano proveniente de la ganadería es importante por su contribución como gas de efecto invernadero. Esta tesis busca colaborar en el entendimiento de las emisiones de metano entérico en animales alimentados con dietas forrajeras con diferentes niveles de fibra. Para ello, esta tesis se dividió en dos partes. En la primera, se realizó un experimento utilizando 30 novillos para carne, alimentados en comederos automatizados, donde se cuantificó las emisiones originadas de la alimentación utilizando la técnica SF6. Los animales se dividieron en dos grupos con dos dietas forrajeras de distinta calidad y contenido de fibra. En la segunda parte, se evaluó el desempeño (exactitud y precisión) de las predicciones de seis ecuaciones de estimación de emisiones de CH4 y se compararon con observaciones de 29 estudios realizados con dietas forrajeras. En lo experimental, las emisiones absolutas de metano entre ambas dietas no fueron diferentes (p > 0,05). Sin embargo, las intensidades de emisión por kg de materia seca consumida y por kg ganado de peso (g CH4/DMI y g CH4/ADG) fueron inferiores en los animales consumiendo la dieta de baja fibra (p < 0,05). Por otro lado, el modelo que presentó el mejor desempeño fue el modelo del nivel 2 de IPCC 2006 (r² = 0,7, RMSE = 74 g). La utilización de una dieta forrajera de mejor calidad, con menor contenido de fibra, disminuyó las intensidades de emisión de metano. El uso de un modelo de predicción ajustado para dietas forrajeras permitirá predecir mejor las emisiones originadas de animales alimentados bajo este tipo de dietas

The collection is a work-in-progress, seeking to record the oral history of as many Lost Boys/Girls as are willing, and will be used in a future book.Age: 24Region: Upper NileThis picture and bio was donated to the "Lost Boys Found" oral history project from The Arizona Lost Boys Cente
Daniel Emmett postcard
No full textPostcard of Daniel Emmett and his home in Mount Vernon, Ohio. Emmett is considered to be the author of the antebellum song "Dixie," written in 1859, which became the unofficial song of the Confederate soldiers during the American Civil War. He was born in Mount Vernon in 1815 and taught himself the fiddle, and later became associated with minstrel shows and helped to define that genre. Minstrel shows traveled around the United States, presenting skits and musical performances. Emmett also composed many other songs, including "Old Dan Tucker," "Turkey in the Straw," and "The Blue Tail Fly." He died in 1904
