Abstract We report on a potential method to separate sugars by using the specific interaction between fullerenes and saccharides in liquid chromatography (LC). Aromatic rings with high electron density are believed interact strongly due CH–π and/or OH–π interactions. In this study, fullerene-bonded columns were used LC under aqueous conditions. As result, 2-aminobenzamide-labeled glucose homopolymer (Glcs) was effectively separated both C60 C70 range of Glc-1 Glc-20 blood level being...

Summary This paper discusses applicability of the microtremor survey to complicated structure in mineral exploration, taking epithermal vein systems as an example through a case study at Hishikari mine, largest and richest gold deposit Japan. In general, itself is relatively difficult target for geophysical exploration. Almost all techniques are deployed aiming detection some physical phenomena associated mineralization, e.g. basement highs hydrothermal alteration. The experimental this...

Diffuse brain injury is classified by coma time clinically. If less than 6 hour, it called concussion, and if hour or more, Axonal Injury (DAI), but the difference of occurrence mechanism these two in neural scale has not been understood yet. Therefore, needed to clarify relationship between deformation parenchyma tolerance function. Although electrophysiological change axonal function important, various studies have conducted based on morphological axon. The purpose this study examine...

It is important to improve the efficiencies of motors overcome problems such as decreasing energy reserves and environmental pollution. Superconductors are promising for developing high-efficiency motors. However, superconducting wires must be kept in critical conditions AC loss needs minimized. In this paper, a design interior permanent magnet synchronous motor (IPMSM) proposed that reduces loss. The characteristics normal-conducting IPMSMs compared. IPMSM has low very high efficiency at speeds.
