A weeding-duration model for Abies sachalinensis plantations in Hok-kaido, northern Japan

引用

Journal of Forestry.Research 2013年第1期24卷 131-136页

作者： Masahiko nakagawa Doto Station Forestry Research InstituteHokkaido Research OrganizationShintoku-choHokkaido081-0038Japan

I developed a weeding-duration model for Sakhalin fir （Abies sachalinensis （Fr. Schmidt） Masters） plantations that employ. a generalized linear model. The number of y.ars following planting that weeding is necessary.is the response variable, and elevation, slope steepness, maximum snow depth, annual precipitation, geology. soil, site index, slope aspect, and vegetation ty.e are explanatory.variables. Among the explanatory.variables, geology. soil, slope aspect, and vegetation ty.e are categorical data. A Poisson distribution is assumed for the response variable, with a log-link function. Elevation, slope steepness, maximum snow depth, annual precipitation, site index, and vegetation ty.e had a significant effect on weeding duration. Among the eight models with the smallest Akaike information criterion （AIC）, I chose the model with no multicollinearity.among the explanatory.variables. The weeding-duration model includes site index, maximum snow depth, slope steepness （angle） and vegetation ty.e as explanatory.variables; elevation and annual precipitation were not included in the selected model because of multicollinearity.with maximum snow depth. This model is useful for cost-benefit analy.es of afforestation or reforestation with Abies sachalinensis.

On the Numerical Modeling of the Deep Mantle Water Cy.le in Global-Scale Mantle Dy.amics:The Effects of the Water Solubility.Limit of Lower Mantle Minerals

引用

Journal of Earth Science 2017年第4期28卷 563-577页

作者： Takashi nakagawa Department of Mathematical Science and Advanced Technology Japan Agency for Marine-Earth Science and TechnologyYokohama 236-0001Japan

Water is the most important component in Earth sy.tem evolution. Here, I review the current understanding of the fate of water in the mantle dy.amics sy.tem based on high-pressure and temperature experiments, geochemical analy.es, seismological and geomagnetic observations, and nu- merical modeling of both regional- and giobal-scale mantle dy.amics. In addition, as a numerical ex- ample, I show that the water solubility.of the deep mantle is strongly.sensitive to global-scale water cir- culation in the mantle. In a numerical example shown here, water solubility.maps as functions of tem- perature and pressure are extremely.important for revealing the hy.rous structures in both the mantle transition zone and the deep mantle. Particularly. the water solubility.limit of lower mantle minerals should be not so large as ~100 ppm for the mantle transition zone to get the largest hy.rous reservoir in the giobal-scale mantle dy.amics sy.tem. This result is consistent with the current view of mantle water circulation provided by.mineral phy.ics, which is also found as a hy.rous basaltic crust in the deep mantle and the water enhancement of the mantle transition zone simultaneously. In this paper, I also discuss some unresolved issues associated with mantle water circulation, its influence on the onset and stability.of plate motion, and the requirements for developing Earth sy.tem evolution in mantle dy. namics simulations.

Is the RENP Process Probable for a Xe Atom Embedded in Quantum Solid?

引用

Journal of Applied Mathematics and Phy.ics 2014年第9期2卷 862-868页

作者： S. T. nakagawa y. Senju Graduate School of Science Okayama University of Science Okayama Japan

We studied the excitation spectra in the case of Xe@(p-H2)n embedded in a solid-state parahy.rogen, making use of the ab initio molecular orbital method (QMO), in order to seek the possibility.of the radiative emission of the neutrino pair (RENP) process that may.be associated with the E1 × M1 transition processes. By.means of a QMO calculation, the remarkable matrix effect was found in the structure of the electronic states. Three E1-ty.e excitation bands (ε1, ε2, ε3, in the order of increasing energy. in the UV absorption were found. In the present preliminary.calculation, the second was too close to be clearly.well distinguished as an independent peak observed in the last experiment. Nevertheless, across the second (ε2) band, two associated bands that may.link to the M1-ty.e transition were found. Therefore, the M1-ty.e de-excitation process may.be probable with the help of intensity.borrowing from the ε2 band, which may.support the probability.of the RENP process.
