Indoor mold levels typically increase after natural disasters, flooding, and water damage. Eurotium herbariorum is the sexual stage of Aspergillus glaucus. Case Presentation A 66-year-old, Japanese male, ex-smoker had been diagnosed with bronchial asthma when he was five years old; he achieved remission at the age of 13 years. He was displaced from his home during the Great East Japan Earthquake on March 11, 2011 and moved to temporary housing in Miyagi Prefecture in June 2011. He experienced the first episode of chest tightness, coughing, and wheezing in February 2012, when he again was diagnosed as having bronchial asthma. Mycofloral surveillance detected high counts of Eurotium in the air of his bedroom, kitchen, and living room, with a maximal fungal count of 163,200 colony-forming units per cubic meter (CFU/m3). Although Cladosporium and Penicillium typically predominate in the indoor air of residential dwellings, only low levels of these organisms were present in the patient's home. Morphologic identification confirmed the isolates as E. herbariorum. The patient had positive reactions to E. herbariorum in skin prick testing and the presence of antigen-specific precipitating antibodies to E. herbariorum. Computed tomography of the chest in August 2013 revealed central bronchiectasis and bronchial wall thickening. The patient experienced late reactions after provocation testing with E. herbariorum. This report presents the rare case of a patient who developed allergic bronchopulmonary mycosis (ABPM) due to exposure to E. herbariorum during temporary housing after the Great East Japan Earthquake.

Atomic absorption analysis has been used to study the impurity diffusion of copper in nickel in the temperature range between 1080 and 1613 K. The linear Arrhenius plot of the impurity diffusion coefficient of Cu in Ni has been expressed as follows:(This article is not displayable. Please see full text pdf.) \ oindentAtomic absorption analysis is found to be useful to measure the penetration profile for the impurity diffusion in metals where suitable radioisotope as a tracer is unavailable or the half-life of radioisotope is very short.

Calculations of temperature coefficients of the elastic surface wave velocity and delay time were performed for the propagation along the X axis of a rotated Y cut plane of LiNbO3 and LiTaO3. Measurements of the temperature dependence of the delay time of the elastic surface wave were also performed for the propagation along the X axis of a 131° rotated Y cut plane of LiNbO3 in the temperature range from liquid He to room temperatures. The experimental value, 70×10-6/°C, of the temperature coefficient of the delay time from 173 K to room temperature agrees with the calculated value, 72.7×10-6/°C. However, the coefficient becomes 16×10-6/°C near liquid He temperatures.
