In order to create Fe2O3 and Fe2O3·H2O nanoparticles, various polymers were used as dispersing agents, and the resulting effects on the dispersibility and nanoparticulation of the iron oxides were evaluated. It was revealed that not only the solution viscosity but also the molecular length of the polymers and the surface tension of the particles affected(More)
We examined whether an additive treatment with an angiotensin receptor blocker, olmesartan, reduces the mortality and morbidity in hypertensive patients with chronic heart failure (CHF) treated with angiotensin-converting enzyme (ACE) inhibitors, β-blockers, or both. In this prospective, randomized, open-label, blinded endpoint study, a total of 1147(More)
BACKGROUND Bronchial asthma is a chronic inflammatory disease that has a severe impact on health worldwide. METHODS A survey of 10,771 patients with bronchial asthma in the Tama region, Tokyo was conducted for 5 years to examine treatment and quality of life (QOL). Subjects were patients aged ≥ 16 years and their physicians who replied to a questionnaire(More)
For the purpose of exposure assessment in epidemiological studies on mobile phone use and brain cancer risk, 76 Japanese mobile phones were classified, for different use conditions (mobile phone held on left or right side of face, in tilt or cheek position, with the antenna in or out), into a small number of categories by using a cluster analysis of spatial(More)
The microstructure at the interface of diffusion-bonded joints of oxygen-free high-conductivity copper for two kinds of surface conditions, with and without argon ion bombardment treatment, was investigated using scanning and high-resolution transmission electron microscopy and energy-dispersive X-ray spectroscopy. The results showed that argon ion(More)
The measurement of air temperature is strongly influenced by environmental factors such as solar radiation, humidity, wind speed and rainfall. This is problematic in low-cost air temperature sensors, which lack a radiation shield or a forced aspiration system, exposing them to direct sunlight and condensation. In this study, we developed a machine(More)
We propose a method which adaptively selects InfiniBand transport services used for source and destination peers to improve performance while limiting memory consumption of the MPI library. There are two major choices of IB transport services available, i.e., Reliable Connection (RC) and Dynamically Connected (DC), each of which is selected for each pair of(More)
