小学校の学習内容と中学校技術・家庭科技術分野との関連<教育科学>

The relation between learning content in the elementary school and Technology education in junior high school was investigated. The object of the investigation was ministry’s curriculum guideline. As the result, the relation between Technology education and Society, Science, Arithmetic, Drawing and Handicrafts and Life Environment Studies was confirmed. It is important to make the guidance plan in respect of this relation, when the technology education course studys it.textapplication/pdfdepartmental bulletin pape

Observation of the Ψ(4415)→ D\bar{D}_2^* (2460) Decay Using Initial-State Radiation

We report measurements of the exclusive cross section for e^+e^-　→D^0D^-π^+ over the center-of-mass energy range 4.0 GeV to 5.0 GeV with initial-state radiation and the first observation of the decay Ψ(4415)→D^0D^-π^+. From a study of the resonant substructure in Ψ(4415) decay we conclude that the Ψ(4415)→D^0D^-π^+ decay is dominated by Ψ(4415)→D\bar{D}_2^*(2460). We obtain B(Ψ(4415)→D^0D^-π^+_nonresonant)/ B(Ψ(4415)→D\bar{D}_2^*(2460)→D^0D^-π^+)<0.22 at 90% C.L. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 673 fb^{-1}.journal articl

Tritrophic interactions between a fungal pathogen, a spider predator, and the blacklegged tick

Data used in publication: "Tritrophic interactions between a fungal pathogen, a spider predator, and the blacklegged tick." Please see paper for study details

Effects of Acorn Density on Mouse and Chipmunk Densities

<p>Shows effects of acorn density (acorns per square meter) in year <i>t</i>−2 on (A) mouse <i>(P. leucopus)</i> density (number per 2.25-ha grid) in year <i>t</i>−1 and (B) chipmunk <i>(T. striatus)</i> density (number per 2.25-ha grid) in year <i>t</i>−1. (C) Correlation between mouse density and chipmunk density across plots and years. </p

Effects of Population Density of Eastern Chipmunks <i>(T. striatus)</i> on DON

<p>Shows relationship between number of chipmunks per 2.25-ha grid in year <i>t</i>−1 and DON (number per 100 m²) in year <i>t.</i> This regression model for DON had the most support. </p

Effects of Acorn and Rodent Densities on DIN

<div><p>(A) Effects of the product of acorn density (acorns per square meter) in year <i>t</i>−2 and mouse <i>(P. leucopus)</i> density (number per 2.25-ha grid) in year <i>t</i>−1 on the density of B. burgdorferi-infected nymphs (number per 100 m²) in year <i>t.</i> This regression model for DIN had the most support. </p> <p>(B) Effects of the product of acorn density (acorns per square meter) in year <i>t</i>−2 and chipmunk <i>(T. striatus)</i> density (number per 2.25-ha grid) in year <i>t</i>−1 on the density of B. burgdorferi-infected nymphs (number per 100 m²) in year <i>t.</i> This regression model for DIN had nearly as much support (AIC_corr) as the mouse model (A) and a higher <i>r</i>² value. </p></div

Time Series of Acorn, Tick, and Chipmunk Densities on Study Plots

<p>Shows time series of acorn density (acorns per square meter), chipmunk density (number per 2.25-ha grid), and DON (number per 100 m²) on the two longest-established study plots, Henry Farm (A) and Teahouse (B). Note that, typically, chipmunk density tracks acorn density with a 1-y lag, and DON tracks chipmunk density also with a 1-y lag. </p

Diagram of Life Cycle of the Blacklegged Tick <i>(I. scapularis)</i>

<p>Shows the four life stages, egg, larva, nymph, adult, and the times during the life cycle that both abiotic (GDD, PPT), and biotic (acorns and various hosts) factors might exert influence. Year <i>t</i> is the year during which nymphal ticks seek hosts, including humans, and represents the focal year with respect to risk of exposure. </p
