Sediment transport capacity of concentrated flows on steep loessial slope with erodible beds

open access: yesScientific Reports, 2017
Previous research on sediment transport capacity has been inadequate and incomplete in describing the detachment and transport process of concentrated flows on slope farmlands during rill development.

Centennial- to millennial-scale hard rock erosion rates deduced from luminescence-depth profiles [PDF]

open access: yes, 2018
The measurement of erosion and weathering rates in different geomorphic settings and over diverse temporal and spatial scales is fundamental to the quantification of rates and patterns of earth surface processes. A knowledge of the rates of these surface

High Healthcare Utilization Preceding Diagnosis with Juvenile Idiopathic Arthritis

open access: yesArthritis Care &Research, Accepted Article.
Objective Though early diagnosis improves long‐term outcomes, Juvenile Idiopathic Arthritis (JIA) patients often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize healthcare utilization in the year preceding diagnosis.

Different Selectivity in Fungal Communities Between Manure and Mineral Fertilizers: A Study in an Alkaline Soil After 30 Years Fertilization

open access: yesFrontiers in Microbiology, 2018
Fertilizer application has contributed substantially to increasing crop yield. Despite the important role of soil fungi in agricultural production, we still have limited understanding of the complex responses of fungal taxonomic and functional groups to ...

Erosion and Erosion-Corrosion

open access: yesZairyo-to-Kankyo, 2008
エロージョン・コロージョン現象の複雑な発生機構と紛らわしい用語の定義のために,発電所の配管部に時として発生する「エロージョン・コロージョン」を理解することは非常に難しい.最近,エロージョン・コロージョンの代わりに,FAC (流れによって加速される腐食) という言葉が,発電所に用いられる配管材料の減肉現象として紹介されている.しかしながら,FACは必ずしも良く理解されていないし,エロージョン・コロージョンとも比較がなされていない.そこで,本稿ではエロージョン,エロージョン・コロージョンおよびFAC現象の理解を深め,再確認をするために,まず,エロージョンおよびエロージョン・コロージョンの起源,定義およびこれまでの基礎的な見解についてまとめた.次に,流速と環境の腐食性を軸にし,エロージョン ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Improving water-use efficiency by decreasing stomatal conductance and transpiration rate to maintain higher ear photosynthetic rate in drought-resistant wheat

open access: yesCrop Journal, 2017
In wheat, the ear is one of the main photosynthetic contributors to grain filling under drought stress conditions. In order to determine the relationship between stomatal characteristics and plant drought resistance, photosynthetic and stomatal ...
