Numerical simulation of effect of convection-diffusion on oxygen transport in microcirculation

引用

Applied Mathematics and Mechanics(English Edition) 2015年第2期36卷 179-200页

作者： N.ZHAO K.IRAMINA graduate school of Systems Life Sciences Kyushu University Department of Informatics Graduate School of Information Science and Electrical Engineering Kyushu University

The entire process of oxygen transport in microcirculation by developing a3 D porous media model is calculated numerically with coupled solid deformation-fluid seepage-convection and diffusion. The principal novelty of the model is that it takes into account volumetric deformation of both capillary and tissues resulting from capillary fluctuation. How solid deformation, fluid seepage, and convection-diffusion combine to affect oxygen transport is examined quantitatively：（1） Solid deformation is more significant in the middle of capillary, where the maximum value of volumetric deformation reaches about 0.5%.（2） Solid deformation has positive influence on the tissue fluid so that it flows more uniformly and causes oxygen to be transported more uniformly, and eventually impacts oxygen concentration by 0.1%–0.5%.（3） Convection-diffusion coupled deformation and seepage has a maximum（16%） and average（3%） increase in oxygen concentration,compared with pure molecular diffusion. Its more significant role is to allow oxygen to be transported more evenly.

Livelihood Factors and Household Strategies for an Unexpected Climate Event in Upland Northern Laos

引用

Journal of Mountain Science 2015年第2期12卷 483-500页

作者： Phanxay INGXAY Satoshi YOKOYAMA Isao HIROTA Department of Geography Graduate School of Environmental Studies Nagoya University graduate school of Bioagricultural Sciences Nagoya University

Climate events pose major challenges to food production and the livelihoods of rural inhabitants in northern Laos, where upland rice using swidden production is an important crop. The onset of the rainy season in this area is one such climate event, and it has occurred earlier and with less regularity in recent years. Not all households are able to cope with these changes. This study examines the ability of local farmers to cope with rice insufficiency. This investigation also clarifies household strategies in dealing with the climate event. We randomly interviewed 63 of 95 household heads, and performed a paired sample t test to examine the significance of differences in three household groups between the 2010 normal climate and the 2011 climate event. The groups were categorized according to rice selfsufficiency in 2011: groups I are households with rice self-sufficiency, group II are those facing a rice shortage of up to 3 months, and group III are those with insufficient rice for over 3 months. We also conducted a one-way ANOVA to examine the significance of differences in livelihood strategies among the three groups. We found that the household labor force was the most important factor in enhancing the villagers' ability to deal with the climate event and that the level of impact of that event shaped their coping strategies. Households with substantial labor force had more options for coping strategies than those with smaller ones. The villagers faced different levels of impact and adopted differentcoping strategies accordingly. Non-timber forest product collection was the principle livelihood strategy in response to non-climate factors such as education, access to health services, provision of equipment and clothing, and overcoming the impact of the climate event. Households heavily affected by the early rainy season onset tended to engage in intensive activities such as off-farm activity and outside work, rather than their major livelihood activities in the v

Molecular Functions of Oxygen-Evolving Complex Family Proteins in Photosynthetic Electron Flow

引用

Journal of Integrative Plant Biology 2010年第8期52卷 723-734页

作者： Kentaro Ifuku Seiko Ishihara Fumihiko Sato graduate school of Biostudies Kyoto University

Oxygen-evolving complex （OEC） protein is the original name for membrane-peripheral subunits of photosystem （PS） II. Recently, multiple isoforms and homologs for OEC proteins have been iden- tified in the chloroplast thylakoid lumen, indicating that functional diversification has occurred in the OEC family. Gene expression profiles suggest that the Arabidopsis OEC proteins are roughly categorized into three groups： the authentic OEC group, the stressresponsive group, and the group including proteins related to the chloroplast NAD（P）H dehydrogenase （NDH） complex involved in cyclic electron transport around PSI. Based on the above gene expression profiles, molecular functions of the OEC family proteins are discussed together with our current knowledge about their functions.

Measurement of modulation induced by interaction between bubble motion and liquid-phase motion in the decaying turbulence formed by an oscillating-grid

引用

Particuology 2013年第2期11卷 158-169页

作者： Yasuyuki Nagami Takayuki Saito graduate school of Engineering Shizuoka University graduate school of Science and Technology Shizuoka University

In multiphase flows, dynamical gas-liquid interactions are essential for in-depth understanding of their multi-scale phenomena and complicated structures. The purpose of the present study is to clearly extract the modulation in bubble motion and liquid motion induced by bubble-liquid interaction and to discuss the relations between bubble motion and liquid-phase motion. For this particular purpose, the decaying turbulence formed in a cylindrical acrylic pipe （diameter 149 mm, height 600 mm） by using an oscillating- grid was employed. Uniform single bubbles were launched from an in-house bubble launching device into the decaying turbulence. By comparing the bubble motion in the stagnant water with that in the oscillating-grid decaying turbulence, the transition of the 2D bubble motion （i.e., zigzagging motion） to 3D motion was enhanced in the latter. In addition, the initial conditions of the bubble motion that was not influenced by the ambient turbulence were carefully confirmed. In the area where the bubble motion started to translate from 2D motion into 3D motion, the modulation of ambient liquid-phase motion was obtained by PIV/LIF measurement. By combining these results, we quantitatively discussed the modulation of the bubble motion and ambient liquid-phase motion and considered the dominant factor for the enhancement to be the bubble-liquid interaction.

Fabrication of Co2Fe（Al,Si） and Co2Fe（Al,Si）/MgO on Ge（111） Substrate and Its Magnetic Properties

引用

Journal of Electronic Science and Technology 2019年第2期17卷 109-115页

作者： Kohei Kataoka Nobuki Tezuka Masashi Matsuura Satoshi Sugimoto graduate school of Engineering Tohoku University

We investigated the interfacial effects on magnetic properties in Co2Fe(Al,Si)/Ge (CFAS/Ge) and CFAS/MgO/Ge systems to demonstrate the effects of the interface structure on magnetic properties. CFAS and CFAS/MgO were deposited on the i-Ge(111) substrate. In-situ reflection high energy electron diffraction (RHEED) patterns showed epitaxially grown CFAS and MgO on Ge(111). According to the X-ray diffraction (XRD)φ-scan of CFAS(220), we determined that the crystallographic orientation relationships were CFAS(111)//Ge(111) and CFAS(111)//MgO(111) Ge(111). The magnetic properties were measured by the vibrating sample magnetometer (VSM) and the saturation magnetization Ms value of CFAS with 2-nm thick MgO reached the value of L21 ordered one. A uniaxial magnetic anisotropy behavior was observed both in CFAS/Ge and CFAS/MgO/Ge structures after annealing. We confirmed the behavior did not only originate from the CFAS/Ge interface but also CFAS/MgO and the ordering structure.

PREDICTING RELEVANT EMPTY SPOTS IN SOCIAL INTERACTION

引用

Journal of Systems Science & Complexity 2008年第2期21卷 161-171页

作者： Yoshiharu MAENO Yukio OHSAWA graduate school of Systems Management Tsukuba University school of Engineering University of Tokyo

An empty spot refers to an empty hard-to-fill space which can be found in the records of the social interaction, and is the clue to the persons in the underlying social network who do not appear in the records. This contribution addresses a problem to predict relevant empty spots in social interaction. Homogeneous and inhomogeneous networks are studied as a model underlying the social interaction. A heuristic predictor function method is presented as a new method to address the problem. Simulation experiment is demonstrated over a homogeneous network. A test data set in the form of market baskets is generated from the simulated communication. Precision to predict the empty spots is calculated to demonstrate the performance of the presented method.
