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
Estudios en el género Cortaderia (Poaceae). III. Cortaderia peruviana, nuevo sinónimo de C. hieronymi
No full textCortaderia hieronymi y C. peruviana han sido consideradas como dos especies diferentes. Sin embargo, distintos autores difieren en sus límites morfológicos y en su distribución geográfica. Un análisis de componentes principales sobre la base de los caracteres tradicionalmente utilizados para delimitar estas especies no permitió formar grupos discretos para cada taxón. Además, el estudio de los ejemplares tipo y de las descripciones originales, complementado con estudios de campo, permite establecer que C. peruviana es parte de la variabilidad morfológica de C. hieronymi; por lo tanto, se propone su sinonimia. Se amplía la caracterización y distribución geográfica de la especie.Studies in the genus Cortaderia (Poaceae) III. Cortaderia peruviana, a new synonym of C. hieronymi. Cortaderia hieronymi and C. peruviana have been considered as two different species. However, different authors differ in their morphological limits and their geographical distribution. A Principal Components Analysis based on characters traditionally used to delimit these species did not show discrete groupings for each taxon. In addition, the study of type species and their original descriptions, complemented with field studies, allows to establish that C. peruviana is part of the morphological variability of C. hieronymi; therefore, their synonymy is proposed herein. A detailed characterization and geographic distribution of the species is given.Fil: Testoni, Daniel. Consejo Nacional de Investigaciones Científicas y Técnicas.

Studies in the genus Cortaderia (Poaceae) II. Cortaderia atacamensis, a new synonym of C. speciosa
No full textEn esta contribución a la sistemática del género Cortaderia se propone la sinonimización de C. atacamensis y C. speciosa. Hasta ahora el binomio Cortaderia atacamensis ha sido considerado un sinónimo de C. jubata. Sin embargo, el estudio de los ejemplares tipo y de las descripciones originales, complementado con estudios de campo, demostraron que C. atacamensis es un sinónimo de C. speciosa (una especie nativa de las regiones desérticas desde Perú hasta el norte de la Argentina y Chile), distinta de C. jubata (una especie típica de los bosques andinos desde Colombia hasta el norte de la Argentina). Se presentan una caracterización morfológica y una clave para separar ambas especies.In this contribution to the systematics of the genus Cortaderia the synonymization of C. atacamensis and C. speciosa is proposed. Until now the binomial Cortaderia atacamensis has been considered a synonym of C. jubata. Nevertheless, the study of the type specimens and original descriptions, complemented with field studies, demonstrated that C. atacamensis is a synonym of C. speciosa (a species native to the desertic regions from Peru to northern Argentina and Chile), rather than of C. jubata (a species typical of the Andean forests from Colombia to northern Argentina). A morphological characterization and a key to separate the two species are provided.Fil: Testoni, Daniel. Consejo Nacional de Investigaciones Científicas y Técnicas.

(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

No full textabstract: Daniel was a little boy when the war came to his village. He witnessed people being shot and running for shelter. There was no food or water so he drank urine and ate tree leaves.
“Lost Boys Found” is an ongoing, interdisciplinary project that is collecting, recording and archiving the oral histories of the Lost Boys/Girls of Sudan. 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

Insectos hallados en especies de Araujia (Apocynaceae, Asclepiadoideae) en Argentina
No full textThe results of a survey of the natural enemies of moth plant or “tasi”, species of Araujia (Apocynaceae, Asclepiadoideae), present in Argentina are shown in this paper. 57 species of insects were recorded of which 17 are cited as natural enemies of these species for the first time. Their specificity was determined and their potential use as biological control agents for Araujia hortorum Fourn. was hypothesized. Pseudosphex noverca Schaus (Lepidoptera, Arctiidae), is recorded for the first time in the Buenos Aires province, Argentina.Los resultados de un estudio de los enemigos naturales de las "planta polilla" o "tasi", especies del género Araujia (Apocynaceae, Asclepiadoideae), que se encontraron en Argentina se presentan en este documento.
