Rainfall erosivity and erosivity density in Eastern Ghats Highland of east India

Natural Hazards, 2019
The rainfall erosivity (R-factor in USLE) is the long-term average of the sum of the product of rainfall kinetic energy and its maximum 30-min intensity. Therefore, at most 30-min time intervals pluviograph records are required to calculate R-factor.

Influence of Weft Density on Runoff Erosion Control Performance of Rolled Erosion Control Systems

2021
Rolled erosion control systems (RECSs) used in erosion control application mitigates runoff erosion through micro-barriers created by cross-laid weft yarns of RECS. Increase in number of cross-laid weft yarns (weft density) of RECSs is expected to improve its performance, so coir and jute RECSs with different weft density were prepared and evaluated ...

Chemical Erosion of CFC at High Ion Flux Densities

Physica Scripta, 2001
Former measurements at PSI-1 have been completed by new investigations of the chemical erosion yield for a D+ flux density of 1.8 D+/m2 s in the upgraded plasma generator PSI-2. Si doped CFC samples (NS 31) were exposed to a deuterium plasma. By increasing the neutral gas pressure the electron temperature could be kept below 10 eV.

AB0818 Bone Mineral Density and Metabolic Risk Factors in Patients with Non-Erosive and Erosive Hand Osteoarthritis

Annals of the Rheumatic Diseases, 2014
Background Hand osteoarthritis (OA) and its severe subset erosive hand OA are common causes of pain and morbidity in western world. Few studies investigated differences in systemic bone loss and metabolic diseases between non-erosive and erosive hand OA.

Dependence of rate of physical erosion on orientation and density in mineralised tissues

Anatomy and Embryology, 1984
Bone, dentine and enamel samples were treated with a gas-propelled jet of an abrasive, NaHCO3, which is physically much softer than any of these tissues in their fully mineralised condition. It was nevertheless found that they are all eroded by this treatment, which can therefore be used as a new kind of qualitative test of physical properties relating

MnBi particles with high energy density made by spark erosion

Journal of Applied Physics, 2014
We report on the properties of low-temperature phase (LTP)-MnBi particles produced by the rapid-quenching technique of spark-erosion. The as-prepared powder consists of amorphous, crystalline, and superparamagnetic particles, mostly as porous aggregates. The major fraction of the powder consists of 20–30 nm particles.

Soil Erosion by Concentrated Flow: Shear Stress and Bulk Density

Transactions of the ASAE, 1994
Soil detachment by concentrated flow is often predicted using hydraulic shear stress (t) as a predictor variable. The nature of this relationship is uncertain, however, and may depend on many factors that influence soil resistance to detachment. Research was conducted to better understand the relationship between soil detachment from concentrated flow ...

Investigation of carbon chemical erosion with increasing plasma flux and density

Nuclear Fusion, 2001
The possible reduction of the chemical erosion yield of carbon Ychem with increasing hydrogenic ion flux is a critical issue for the use of carbon based plasma facing materials in future high flux confinement devices. The PISCES linear plasma device is used to assess carbon Ychem through nearly an order of magnitude scan in flux (≤ 1023 s-1 m-2) and ...

Shadow photometric method for measurements of electron density in erosion plasma

International Journal of Heat and Mass Transfer, 2013
Abstract The purpose of this work is property investigation of quasi-stationary plasma formations with high energy content for practical applications in high thermal physics and diagnostic of materials under extreme conditions. Investigated plasma formations are the result of two plasma counter-flows interaction process which is based on high-current

Erosion of a stable density gradient by sedimentation-driven convection

Nature, 1991
STABLE density gradients are common in the world's oceans and lakes, and play a crucial part in their physical, chemical and biological evolution. It has recently been suggested1 that turbidity currents provide an indirect mechanism for eroding this stratification.
