Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]
, 2009 In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).

Soil-water resistivity curve of a tropical soil [PDF]
MATEC Web of Conferences, 2021 The evaluation of soil-water characteristic curve is one of the most important procedures in the matter of understanding the soil behaviour during wetting and drying processes. Even though it might be carried out by established methods, this practice is considered a time-consuming technique, and because of this it is still under-used in comparison with

Effects of Nanoparticles on Double-Stranded RNA Stability in Corn Soil [PDF]
, 2018 Double-stranded RNA (dsRNA) can potentially be used as a pesticide because these molecules trigger an immune response called RNA interference (RNAi). If the expression of essential genes matching the dsRNA sequence are silenced, then the pest dies.

Dinitroaniline Herbicide Resistance and Mechanisms in Weeds
Frontiers in Plant Science, 2021 Dinitroanilines are microtubule inhibitors, targeting tubulin proteins in plants and protists. Dinitroaniline herbicides, such as trifluralin, pendimethalin and oryzalin, have been used as pre-emergence herbicides for weed control for decades.
