The term 'Satoyama' refers to traditional and unique secondary forests in Japan that occupy intermediate zones between villages ('sato') and hills or mountains ('yama'). Satoyama landscapes help sustain ecosystem services and the diversity of secondary natural environments. As Japan relies more heavily on foreign timber imports, the traditional role of Satoyama in providing forest products has diminished, and this has led to their abandonment and poor management. The chemical behavior of cations, anions, and dissolved organic matter in throughfall and stemflow from one such threatened Satoyama system in central Japan was investigated. From autumn to winter, the atmospheric deposition of sulfates and nitrates was 2.5–6.0 times higher compared to the amounts in summer due to the intrusion of air masses from the Asian continent. The dissolved organic matter in the throughfall and stemflow was composed mainly of humic substances and protein derivatives. The deposition fluxes of dissolved organic carbon from throughfall (7.31–10.1 g m^(−2) a^(−1)) and stemflow (1.79–3.84 g m^(−2) a^(−1)) in this study were within ranges seen in temperate forests in previous studies. The deposition flux of sulfates was low compared to that in other forest types because canopy interaction was lower, suggesting higher canopy openness than in primary forests. If a shift from a mixed species Satoyama forest to a conifer-dominated forest occurs after the mass mortality of oak, the deposition flux of dissolved organic carbon and K^(+) might decrease by 33% and 62%, respectively, while NO_(3)^(−) might increase by 20%. In the near future, the degradation of Satoyama landscapes might change the levels of dissolved organic carbon and nitrogen loads, resulting in imbalances in river-ocean linkages affecting forested catchments and aquatic ecosystems in Japan.

Fine and well dispersed Pt-Cu bimetallic nanoparticles stabilized by polyvinyl pyrrolidone （PVP） were synthesized by alkaline polyol method. The molar ratio of Pt to Cu was 1 ： 1. Further, the Pt-Cu bimetallic nanoparticles were supported on alumina and their catalytic behavior in methane combustion was investigated. The as-prepared as well as the supported Pt-Cu nanoparticles were characterized by transmission elec- tron microscopy （TEM）, X-ray photoelectron spectroscopy （XPS）, fractal analysis and X-ray diffraction （XRD）. The dependence of methane combustion on the morphology and surface composition of Pt-Cu nanoparticles was analyzed based on the experimental results.

Hydrogen Production with Steam Reforming of Dimethyl Ether

复旦学报（自然科学版） 2005年第5期44卷 721-722页

Steam reforming of methanol and gasoline is actively researched and developed as hydrogen supply methods for the fuel cells of vehicles and so on. However, these materials have the problems such as the infrastructure, toxicity, difficulty of the reforming, and so forth. Dimethyl ether (DME) does not contain the poisonous substances, and is expected as a clean fuel of the next generation. DME is able to take the place of light oil and LPG, and its physical properties are similar to those of LPG. There is possibility that DME infrastructures will be settled more rapidly than those of hydrogen and methanol, because LPG infrastructures existing are able to use for DME. Then, we have been studying on steam reforming of DME for the hydrogen production.

A study on the interaction between ferric ion and silicic acid in hydrosphere: Si-containing ferruginous deposits formed in neutral hot spring waters

Chinese Journal Of Geochemistry 2013年第1期32卷 27-34页

Five ferruginous deposit samples formed from neutral hot springs were analyzed to determine whether they consisted of a mixture of silica, hydrous iron oxide or iron silicate by differential thermal analysis (DTA), infrared (IR) spectroscopy, powder X-ray diffraction (XRD), and 57Fe Mssbauer spectroscopy. The Si/Fe atomic ratios of the deposits ranged from 0.25 to 0.45, and were smaller than those of hisingerite (12), but apparently close to those of siliceous ferrihydrite (0.250.5). Si was confirmed to be present as monomeric or oligomeric silicate from the Si-O stretching vibration frequencies on the IR spectra. Judging from the results of DTA, which minerals starting to produce after heating, and a relationship between Si-O stretching vibration frequency and Si/Fe atomic ratio proposed by Henmi et al. (1981), all the deposits in this study were concluded to be mixtures of various siliceous ferri-hydrites with low and high Si/Fe atomic ratios. Moreover, by comparing the chemical properties of hot spring waters, the formation conditions of siliceous ferrihydrite were also discussed.

Background: Previous studies have shown that the prevalence of irritable bowel syndrome (IBS) is 10% - 15% in the general population. IBS is a functional gastrointestinal disorder characterized by abdominal pain, abdominal discomfort and disordered defecation associated with a stressful lifestyle. However, the cause of IBS has not been clarified yet. Based on a similar, previous study in Japan, this study investigated the prevalence of IBS and the relationship between IBS and stress, lifestyle and dietary habits among nursing and medical school students in China. Methods: Designed to investigate IBS symptoms, life- style, dietary intake, life events, anxiety and depresssion, a blank self-administrated questionnaire was used to survey 2500 nursing or medical students in China. Questionnaires were collected from 2141 stu- dents (85.6%) and responses obtained from 1934 students (90.3%) were analyzed. Results: On the whole, the prevalence of IBS was 32.1% in this study, 26.6% in males and 33.6% in females. In females, the IBS group showed a bedtime later than that in the non-IBS group, and the length of time asleep in the IBS group was shorter than that in the non-IBS group (p p = 0.005). In females, the IBS group showed a frequency for the intake of vegetables and potatoes that was lower than that of the non-IBS group (p = 0.007, p = 0.023). The prevalence of IBS among nursing and medical school students in China (32.1%) was significantly lower than that in Japan (35.5%). Especially, the number of females in the constipation dominant IBS subgroup in China (11.8%) was less than that found in Japan (20.4%). Conclusions: The prevalence of IBS was high among nursing and medical students in China, but lower than that shown in Japan.
