In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A test patch should be as clean as possible. Contamination of a patch can influence the results significantly. Bresle patch injected with 15ml water as in ISO 8502-6 Annex A. The ISO 8502-6 standard prescribes in annex A that certified patches shall be used. This annex describes a stress test to ensure patch adhesion and wash ability.
The development of quantitative methods for livestock production includes mathematical modelling based in plant-herbivore or predator-prey models to forecast and optimise meat production. An example is the Predator-Prey Grassland Livestock Model (PPGL) [7] to address the dynamics of the combined grass-animals system as a predator-prey dynamical ...
The paint fills the grooves, and the location where a regular, significant "pepperyness" in the appearance of the coating appears, marks the coarsest-ground dispersed particles. [3] This is the point where oversized particles start to appear in high density and determines the rating for that material. [ 4 ]
A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
For the 2023 testing year in Wisconsin, 1,586 deer were CWD-positive out of 17,314 analyzed, or 9.2%, according to the DNR. The number and the percentage of positives were highest since the DNR ...
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
MADISON — The Wisconsin Department of Natural Resources confirmed cases of viruses that cause epizootic hemorrhagic disease (EHD) in the counties of Chippewa, Jackson and Waukesha, according to ...
