Influences of tree characters on throughfall and stemflow from rainfall and fog in Popa Mountain Park, Myanmar

引用

Journal of Forestry Research 2024年第6期35卷 210-219页

作者： Yadanar Zaw hiroki Oue The United Graduate School of Agricultural Sciences Ehime University3-5-7 TarumiMatsuyamaEhime 790-8566Japan Graduate School of Agriculture Ehime University3-5-7 TarumiMatsuyamaEhime 790-8566Japan

Available water for communities is insufficient in the central part of Myanmar due to limited rainfall and surface water resources. Over the last two decades, afforestation and reforestation projects have been implemented in this region to provide sufficient water to local communities, expecting forested areas to store more rainwater than other land uses. However, there has been no research and very limited information on rainfall partitioning into throughfall(TF) and stemflow(SF), particularly concerning tree characters. Gross rainfall, TF under different canopy types, and SF of different tree types were measured in 2019. TF and SF were frequently observed even without rain but under foggy conditions. Therefore, both were partitioned into TF and SF from rainfall and fog individually. Sparser canopies resulted in larger TF from rainfall than denser canopies. However, a denser canopy delivered larger TF from fog than a sparser one. TF rates from rainfall in sparser and denser canopies were 54.5% and 51.5%, respectively, while those from fog were 15.2% and 27.2%, respectively. As a result, total TF rate in the denser canopy(70.7%) was significantly larger than that from the sparser one(64.3%). Short trees with small crown projection area and smooth bark(Type Ⅰ) resulted in larger SF from rainfall than taller trees with large crown projection area and rough bark(Type Ⅱ). However, Type Ⅱ trees resulted in larger SF from fog. SF rates by rainfall from Type Ⅰ and Ⅱ trees were 17.5% and 12.2%, respectively, while those by fog were 22.2% and 39.5%, respectively. No significant total SF rates were found for Type Ⅰ(22.5%) and Ⅱ trees(20.1%). A denser canopy results in larger TF, and Type Ⅰ trees result in larger SF. In an area where foggy conditions occur frequently and for a lengthy period, however, Type Ⅱ trees will result in larger SF. These three tree characters(dense canopies, short trees with small crown projection area and smooth bark, and tall trees with large crown p

Relapse of prostate cancer from the viewpoint of total gland volume kinetics theory

引用

Asian Journal of Andrology 2015年第6期17卷 904-907页

作者： hiroki Watanabe Director Watanabe Memorial Choumei ResearchLaboratory Shiga Japan Honorary Professor KyotoPrefectural University of Medicine and Meiji Universityof Integrated Medicine Kyoto Japan.

In many cases of prostate cancer, changes of prostate volume were measured very frequently after castration by means of transrectal ultrasound. For short-term observations, a factor called as ＂reduction time （tau [τ]）,＂ which means the time required for the volume of ＂effective portion＂（volume responded to castration） to be reduced to one-tenth of its original value, correlated very well with patients＇ prognosis. For long-term observations for relapse, changes of prostate volume could be divided clearly into two types, namely, ＂metastatic progressive type＂ with metastasis without volume increase and ＂local progressive type＂ with remarkable volume increase without metastasis. ＂τ＂ in the ＂local progressive type＂ was far shorter than that in the ＂metastatic progressive type.＂ Much longer survival was obtained when the patient belonged to the ＂local progressive type＂ than to the ＂metastatic progressive type.＂ Thus, ＂τ＂ was the most important and the most reliable factor to predict the prognosis. Based upon these observations, a schematic analysis of prostate cancer relapse was shown.

Linear Stability Analysis on the Influences of the Spatial Variations in Thermal Conductivity and Expansivity on the Flow Patterns of Thermal Convection with Strongly Temperature-Dependent Viscosity

引用

Journal of Earth Science 2014年第1期25卷 126-139页

作者： Arata Miyauchi Masanori Kameyama hiroki Ichikawa Geodynamics Research Center Ehime University

A series of linear stability analysis is carried out on the onset of thermal convection in the presence of spatial variations of viscosity, thermal conductivity and expansivity. We consider the temporal evolution of an infinitesimal perturbation superimposed to a static （motionless） and con- ductive state in a basally-heated planar layer. From the changes in flow patterns with increasing the amplitudes of temperature dependence of viscosity, we identified the transition into the ＂stagnant-lid＂（ST） regime, where the convection occurs only beneath a thick and stagnant-lid of cold fluid at the top surface. Detailed analysis showed a significant increase of the aspect ratio of convection cells in ST regime induced by the spatial variations in thermal conductivity and/or expansivity： the horizon- tal length scale of ST convection can be enlarged by up to 50% with 10 times increase of thermal conductivity with depth. We further developed an analytical model of ST convection which success- fully reproduced the mechanism of increasing horizontal length scale of ST regime convection cells for given spatial variations in physical properties. Our findings may highlight the essential roles of the spatial variation of thermal conductivity on the convection patterns in the mantle.
