Use of fall-cone flow index for soil classification:a new plasticity chart [PDF]

, 2022
Use of the Casagrande-style plasticity chart to classify fine-grained soils using Atterberg’s liquid and plastic limits is ubiquitous in geotechnical engineering.

Nano-cones for broadband light coupling to high index substrates [PDF]

Scientific Reports, 2016
AbstractThe moth-eye structure has been proposed several times as an antireflective coating to replace the standard optical thin films. Here, we experimentally demonstrate the feasibility of a dielectric moth-eye structure as an antireflective coating for high-index substrates, like GaAs.

DETERMINATION OF THE PLASTICITY INDEX USING SLOPE OF FALL CONE FLOW CURVE

, 2023
  This paper presents two simple equations that can be used to compute the plasticity index of soil using the correlation between the slope of the British fall cone flow curve and the plasticity index.

Agricultural Tire Test: Straw Cover Effect on Reducing Soil Compaction by Cargo Vehicles

AgriEngineering
Agricultural cargo vehicles are responsible for applying severe soil pressures. However, the ground straw cover can attenuate the loads applied by wheels to the soil surface.

Fano manifolds of index n-2 and the cone conjecture [PDF]

, 2019
The Morrison–Kawamata Cone Conjecture predicts that the action of the automorphism group on the effective nef cone and the action of the pseudo-automorphism group on the effective movable cone of a klt Calabi-Yau pair have rational, polyhedral ...

Correlação linear e espacial entre o rendimento de grãos do feijoeiro e a resistência mecânica à penetração em um Latossolo Vermelho distrófico Spatial and linear correlation of common bean grain yield with the mechanical penetration resistance in a Dystrophic Red Latosol

Revista Brasileira de Ciência do Solo, 2005
A resistência mecânica à penetração apresentada pelo solo exerce grande influência sobre o desenvolvimento vegetal, uma vez que o crescimento das raízes, assim como o rendimento das culturas, varia de forma inversamente proporcional ao seu valor.

DETERMINATION OF THE  SHRINKAGE LIMIT FROM THE BRITISH FALL CONE FLOW INDEX 

, 2023
   Determining the shrinkage limit using the mercury or wax method is time-consuming and error-prone. This paper presents a model that uses a British cone flow index to compute the shrinkage limit of the soil.
