Particulate inorganic carbonParticulate inorganic carbon (PIC) can be contrasted with dissolved inorganic carbon (DIC), the other form of inorganic carbon found in the ocean. These distinctions are important in chemical oceanography. Particulate inorganic carbon is sometimes called suspended inorganic carbon. In operational terms, it is defined as the inorganic carbon in particulate form that is too large to pass through the filter used to separate dissolved inorganic carbon. Most PIC is calcium carbonate, CaCO3, particularly in the form of calcite, but also in the form of aragonite.
Dynamique des fluidesLa dynamique des fluides (hydrodynamique ou aérodynamique), est l'étude des mouvements des fluides, qu'ils soient liquides ou gazeux. Elle fait partie de la mécanique des fluides avec l'hydrostatique (statique des fluides). La résolution d'un problème de dynamique des fluides demande de calculer diverses propriétés des fluides comme la vitesse, la viscosité, la densité, la pression et la température en tant que fonctions de l'espace et du temps.
Forensic materials engineeringForensic materials engineering, a branch of forensic engineering, focuses on the material evidence from crime or accident scenes, seeking defects in those materials which might explain why an accident occurred, or the source of a specific material to identify a criminal. Many analytical methods used for material identification may be used in investigations, the exact set being determined by the nature of the material in question, be it metal, glass, ceramic, polymer or composite.
