Visible, near infrared, mid infrared or combined diffuse reflectance spectroscopy for simultaneous assessment of various soil properties
TL;DR: In this article, partial least squares regression (PLSR) was used to construct calibration models which were independently validated for the prediction of various soil properties from the soil spectra, including soil pHCa,p H w, lime requirement (LR), organic carbon (OC), clay, silt, sand, cation exchange capacity, exchangeable calcium (Ca), exchangeable aluminium (Al), nitrate-nitrogen (NO3-N), available phosphorus (PCol), exchangeability potassium (K) and electrical conductivity (EC).

The Relationship Between Sphere Size And Settling Velocity
TL;DR: In this paper, the settling velocities in water of 216 glass spheres ranging in size from 50mu to 5000mu in diameter were determined and an empirical equation was derived to give the relationship between sphere size and settling velocity.
