    Tetsuya Theodore Fujita (1920-1998) was born in Kitakyushu, Japan. After receiving his doctorate from Tokyo University in 1950, he began a career as an associate professor at the Kyushu Institute of Technology. In 1953, he began to teach at the University of Chicago, at which he served as a professor until his death in 1998. During his career, Ted Fujita researched meteorology, focusing on severe storms such as microbursts, tornadoes, and hurricanes. He pioneered new techniques for documenting severe storms, including aerial photography and the use of satellite images and film. He also created the Fujita Scale for assessing tornado strength based on a given storm's wind speed and the amount of damage it caused.The Dr. T. Theodore Fujita Collection contains published manuscripts, draft manuscripts, charts, graphs, maps, photographs, photographic negatives, slides, and miscellaneous other materials pertaining to his four decades of meteorological research. A complete set--over 200--reports from Satellite and Mesometeorology Research Project (SMRP) are present. This was his most significant project, documenting for the first time such phenomena as downbursts, multiple-vortex tornadoes, and other groundbreaking meteorological observations and discoveries. Publications, conference proceedings, and research materials from the SMRP, as well as from the National Severe Storms Project (NSSP) and JAWS (Joint Airport Weather Study), comprise the bulk of the collection.Exclusive of these projects is a geographically and chronologically diverse collection of newspapers documenting such events as 1974’s tornadic Superoutbreak, the F-5 Lubbock tornado of 1970, the large Joplin, Missouri tornado of 1973, and dozens of other incidents. Charts--both printed and hand-drawn with attendant graphs, hundreds of photographs, and a wide variety of other research material formats documenting these occurrences is also present.The audio/visual portion of the collection contains such items as the first full-motion satellite images of the Earth, the use of which he pioneered as a meteorological assessment and prediction technique. Audio cassettes and CDs, VHS tapes, 8mm and other sizes of film, and a handful of diskettes are a part of the audio/visual component as well.Access Restrictions: Open for Research.Box 83, Folder 61

    広島湾においてクロダイ稚魚の着底・成育に適した環境条件を把握する目的で,同湾沿岸の稚魚の生息密度を明らかにした。稚魚は2006–2009年6–7月に広島湾内18定点で採集した(n=2,488)。さらに,調査定点のうち最も高い稚魚密度(35.83 inds./100m2)を観測した能美島鹿田において,2013–2016年の7–9月にかけて稚魚を採集し(n=1,588),密度の年変動を観察した。その結果,広島湾の全平均密度は3.78 inds./100m2となり,密度の高い4定点はいずれも厳島,能美島西岸であった。密度が高い定点の特徴として,潮流が物理的に遮られた静穏域の砂浜帯で,淡水流入があることが挙げられた。密度には年変動があり,近年は減少傾向にあることが判明した。広島湾クロダイの資源加入量が低下している可能性が示唆された。To obtain basic information on the optimal nursery grounds for black sea bream Acanthopagrus schlegelii recruits, juvenile density in Hiroshima Bay was calculated. Juveniles (n=2,488) were collected from 18 sampling stations around Hiroshima Bay using surf zone nets during the early summer from 2006 to 2009. to assess the annual fluctuations of juvenile density, samples were continuously caught from one station (St. 1) on the western side of Noumishima Island from 2013 to 2016. Relatively high densities were recorded from four stations (St. 1, 2, 6 and 10) located along the Ohno Seto Strait and the western side of Noumishima Island. These sampling stations shared three common characteristics that likely explain the observed higher juvenile density, namely (1) moderate currents with calm areas protected by physical barrier, (2) sandy muddy beaches (tidal flats) and (3) freshwater inflows or run-off. Juvenile density showed an annual decreasing trend, suggesting that fish stock levels of black sea bream are declining in Hiroshima Bay

    Intranuclear topological distribution of HIV-1 trans-activators

    AbstractSubcellular localization of human immunodeficiency virus type 1 (HIV-1) Tat and Rev was examined using a confocal laser scanning microscope (CLSM). In transfected COS-7 cells, Tat resided exclusively in the perinocleolar region, while Rev infiltrated fully into the nucleoli. The chimeric Tat in which the nucleolar targeting signal was replaced by that of Rev, which retains trans-acting activity of Tat, remained still in the perinucleolar region as wild-type Tat. Perinucleolar distribution of Tat protein suggests the existence of a novel nucleolar architecture that affects transcription

    Humidity Dependence of Charge Transport through DNA Revealed by Silicon-Based Nanotweezers Manipulation

    AbstractThe study of the electrical properties of DNA has aroused increasing interest since the last decade. So far, controversial arguments have been put forward to explain the electrical charge transport through DNA. Our experiments on DNA bundles manipulated with silicon-based actuated tweezers demonstrate undoubtedly that humidity is the main factor affecting the electrical conduction in DNA. We explain the quasi-Ohmic behavior of DNA and the exponential dependence of its conductivity with relative humidity from the adsorption of water on the DNA backbone. We propose a quantitative model that is consistent with previous studies on DNA and other materials, like porous silicon, subjected to different humidity conditions
