ナスカ ダイチ ノ チケイ ブンルイズ ト チジョウエ [PDF]
, 2007 ナスカ地上絵の考古学調査にかかわる地形分類図を試作した｡目的にあわせて,3種類の縮尺精度の地形分類を例示できる｡人工衛星QuickBird画像を画像処理して地形分類の指標とすることが,本章で述べる研究の中心であり,さらにこれらをナスカの地上絵の調査にどのように関連させることができるか,すなわち微地形分類によって分析できる地表面の変化速さ(安定度･不安定度)と地上絵との関係であり,地上絵の作成当時に土地条件が考慮されたのか否か,地上絵の損傷と土地条件(微地形) との関係 ...

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites
Rare Metals, EarlyView.ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.

Some Geomorphic Studies of East Ongul Island; Landform Classification and Morphometry
Antarctic Record, 1961 目的と方法 種々の制約の多い南極地域の地学部門現地調査に側面から協力するために,第1次観測隊の撮影した1万分の1空中写真とそれから図化した5千分の1地形図を基にして,東オングル島の予察的地形分類図の作成と2,3の図上計測を行なった.地形分類は斜面の傾斜(4階級に区分)と表面物質の性状(細粒,粗粒,薄く点在,岩盤露出の4種)を規準に,これら2要素の組合せによって分類単位を設定し,2,3の微地形記号とともに類別図示した.計測は島内に無作為に配布した200地点(Fig.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.
