Hexagonal ceO2 and Eu-doped ceO2 nanoparticles were obtained using a facile microwave-hydro thermal method under mild conditions and their application towards manganese redox flow battery component were studied. The structural properties were studied by X-ray diffraction and indicate that samples present a fluorite structure. Raman spectroscopy shows Eu3＋ ions substitute ce4＋ and generate oxygen vacancies. Electrochemical properties of pure and Eu-doped ceO2 films deposited at graphite substrates investigated by cyclic voltammetry and galvanostatic charge-discharge indicate that dopant concentration affects the electrochemical properties of ceO2. The increase in the reversibility redox of electrochemical systems observed is attributed to coexistence of ce4＋/ce3＋ redox couple confirmed by ***-discharge tests display coulombic and voltage efficiency values of above 80% and 90%, respectively. The obtained specific capacity for ce（0.99）Eu（0.01）O2（372.49 mAh/g） and pure oxide（334.84 mAh/g）indicates that both samples are promising for application in Mn-batteries.

Are trends in SeaWiFS chlorophyll time-series unusual relative to historic variability

Acta Oceanologica Sinica 2010年第2期29卷 1-4页

作者： James A Yoder Maureen A Kennelly Scott c Doney Ivan D lima Woods Hole Oceanographic Institution Woods Hole MA 02540 USA Graduate School of Oceanography University of Rhode Island Narragansett RI 02882 USA

For selected locations in the Atlantic and Pacific Ocean, we compared surface ocean chlorophyll time series extracted from SeaWiFS imagery from 1997-2004 with the results of an ocean coupled circulation and biogeochemical model covering the period 1958-2004. During the 1997-2004 time period, linear trends in model and satellite time series were significantly correlated at most of the 44 sites we studied. Eleven sites were selected for further study, and we used the longer time series of the model to assess whether trends observed during the SeaWiFS period at these 11 sites were unusual in relation to those observed over the longer historical period covered by the model. The results show that the trends observed during the SeaWiFS period were not unusual and fell well within the range in magnitude of linear trends observed in other 8-year periods of model output. This result implies that the SeaWiFS satellite ocean color time series is not yet sufficiently long, on its own, to directly observe any long term changes in phytoplankton chlorophyll that may be occurring in the surface waters of the open ocean as a result of increased ocean stratification linked to global climate changed.

can Intestinal constipation Be Modulated by Prebiotics, Probiotics and Symbiotics?

引用

Food and Nutrition Sciences 2014年第12期5卷 1106-1113页

作者： Monica de Souza lima Sant’Anna célia Lúcia de Luces Fortes Ferreira Departament of Nutrition Federal University of SergipeSao CristovaoBrazil Department of Food Technology Federal University of VicosaVicosaBrazil

The importance of maintaining a healthy intestinal microbiota in the health of the host has been increasingly clarified. This microbiota may appear unbalanced in diseases such as colitis, diarrhea, irritable bowel syndrome and constipation. To rebalance the microbiota and improve the symptoms of constipation, it is recommended to intake prebiotics, probiotics and symbiotics, which works in the modulation of a healthy intestinal microbiota and favors the production of short-chain fatty acids that have a positive effect on intestinal transit. In addition, some studies indicate that there is a relation between the brain and the intestine that influences the behavior of individuals with intestinal dysbiosis. Thus, the reestablishment of the eubiosis in constipated patients through the functional compounds (prebiotics, probiotics and symbiotics) has been showing promising results regarding the modulation of constipation and improvement of the clinical picture. This review will emphasize the relation of prebiotics, probiotics and symbiotics in the modulation of intestinal constipation. New food sources of these compounds should be evaluated for their efficacy, dose and effect to establish a proper management.
