Melt Pool Width Extraction Method in Laser Directed Energy Deposition Based on Variable Step Size Erosion Model

open access: yesIEEE Access
To solve the problem of insufficient melt pool width feature extraction accuracy caused by splash, arc light, and other interferences in the metal deposition process, a melt pool width extraction method based on the variable step size erosion model is ...

Hidráulica do escoamento e transporte de sedimentos em sulcos em solo franco-argilo-arenoso Flow hydraulics and sediment transport in rills of a sandy clay loam soil

open access: yesRevista Brasileira de Ciência do Solo, 2005
A erosão em sulcos caracteriza-se pelo escoamento superficial concentrado de uma lâmina d'água com tensão de cisalhamento suficiente para desagregar o solo, que deforma o sulco e altera as características hidráulicas do escoamento responsável pela ...

Soil Particle-Size Effects on Slope Erosion Under Simulated Rainfall

open access: yesAgronomy
This laboratory-scale study examined how soil particle-size distribution (PSD), especially the median diameter d50, affects slope runoff and sediment yield, and evaluated d50 as a simplified indicator for erosion prediction.

Evaluating the Efficiency of Different Regression, Decision Tree, and Bayesian Machine Learning Algorithms in Spatial Piping Erosion Susceptibility Using ALOS/PALSAR Data

open access: yesLand, 2020
Piping erosion is one form of water erosion that leads to significant changes in the landscape and environmental degradation. In the present study, we evaluated piping erosion modeling in the Zarandieh watershed of Markazi province in Iran based on ...

Pemodelan Pola Transport Sedimen di Perairan Desa Berakit dan Pengudang Kabupaten Bintan

open access: yesRekayasa, 2023
Sedimentation and erosion processes can be influenced by hydro-oceanographic factors. These factors include waves, currents, and tides because they interact directly with the coastal/coastal area.

UAV-Based Soil Erosion Assessment in Mediterranean Agricultural Orchards

open access: yesAgronomy
Unmanned Aerial Vehicle (UAV) imagery has become an important tool for erosion monitoring, but little is known about its application in Mediterranean agricultural systems such as vineyards and olive groves.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Spatial variability of soil water for the entire profile in the critical zone of the Loess Plateau

open access: yesShui kexue jinzhan, 2017
Soil water is central to our understanding of water cycle, groundwater recharge and vegetation restoration in the critical zone of the Loess Plateau. To ascertain the spatial variability of soil water for the entire profile in the critical zone of the ...
