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

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

Meet Daniel Melnick author of The Ash Tree
No full textMeet Daniel Melnick author of The Ash Tree. It tells a timeless story of the romance and marriage between an American Armenian girl and an immigrant who survived the 1915 Armenian Genocide in Turkey. In the aftermath of the Genocide from the 20s through the early 70s, the couple and their three children become vivid, quintessentially American characters, only for tragedy to find them again, echoing the staggering losses of 1915. The cover painting with its frayed, whitewashed frame is by the author’s wife, Jeanette Arax Melnick, and the novel is based partly on the lives of her family. Combining history and fictionalized memoir, The Ash Tree is an important, beautifully written novel of survival, new life, and heartbreak. Available from independent bookstores, Barnes and Noble, and Amazon.com. Further information at www.danielmelnick.com. Price: $25. ISBN: 9780981854762
Determination of the optimal deformation conditions in the new cold pilger rolling process
No full textZawiera bibliogr.The researches presented in this thesis are focused on optimal conditions of metal deformation in the new cold pilger rolling process. Experiments were made on prototype pilger roller, designed due to new concept of tube rolling process. This paper presents physical modelling, numerical simulations, and tube quality assessment, before and after rolling. The strain measurements in working cone were obtained using two methods. The first one is by using professional optical measuring system ARGUS, second one is stereo-photogrammetric method of strain measurement - this technique was proposed by author of thesis. Rolling forces - including metal pressure on rolls, axial force in tube and mandrel, were measured during standard rolling, and also during rolling, where stress variation was added. Tube quality assessment was obtained, by eccentricity and relative wall thickness measurement. In the end, numerical model was prepared, where variety of model calibration was tested. Numerical simulations were verified by comparison with physical modelling results.W pracy zaprezentowano analizę nowego procesu walcowania pielgrzymowego rur na zimno, pod kątem doboru optymalnych warunków odkształcenia metalu. Eksperymenty przeprowadzono na modelowej walcarce pielgrzymowej, wykonanej według nowej koncepcji walcowania pielgrzymowego rur na zimno. Badania obejmowały modelowanie fizyczne, modelowanie numeryczne, oraz ocenę rur przed i po procesie walcowania. Pomiar odkształceń w stożku roboczym wykonano przy wykorzystaniu komercyjnego systemu pomiarowego ARGUS, oraz za pomocą stereofotogrametrycznej metody pomiaru, opracowanej przez autora pracy. Wyznaczono parametry siłowe - nacisk metalu na walce, siła osiowa w rurze i trzpieniu - występujące w czasie procesu walcowania. Zbadano również jak zmienny stan naprężenia wpływa na proces walcowania. Ocena jakości rur po walcowaniu, wykonana została na podstawie pomiarów decentryczności i różnościenności walcowanych rur. Opracowano model numeryczny nowego rozwiązania, na którym testowane były różne kalibrowania urządzenia. Poprawność wykonania modelu, zweryfikowana została na podstawie analizy porównawczej wyników z modelowania fizycznego i symulacji numerycznej.Nr DWM/N75/DAAD/2008 ; N N508 588139 ; 15.11.180.524 ; MCP.ZS.4110-20.4/2008pełny teks
