    Table 2 summarizes the inertia of the first two axes of the PCA and of the MFA applied to Table 1. Group 2 variables contribute to 88.95% of the inertia of the axis 1 of the PCA. The first axis ( F 1 {\displaystyle F_{1}} ) is almost coincident with C: the correlation between C and F 1 {\displaystyle F_{1}} is .976;

  3. Material criticality - Wikipedia

    en.wikipedia.org/wiki/Material_criticality

    Inside an iPhone . Material criticality is the determination of which materials that flow through an industry or economy are most important to the production process. It is a sub-category within the field of material flow analysis (MFA), which is a method to quantitatively analyze the flows of materials used for industrial production in an industry or economy.

  4. Material flow analysis - Wikipedia

    en.wikipedia.org/wiki/Material_flow_analysis

    Material flow analysis (MFA), also referred to as substance flow analysis (SFA), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of human activity on different spatial and temporal scales.

  6. Phosphatidic acid - Wikipedia

    en.wikipedia.org/wiki/Phosphatidic_acid

    PA is a unique phospholipid in that it has a small highly charged head group that is very close to the glycerol backbone. PA is known to play roles in both vesicle fission [12] and fusion, [13] and these roles may relate to the biophysical properties of PA. At sites of membrane budding or fusion, the membrane becomes or is highly curved.

    en.wikipedia.org/wiki/Mercedes-Benz_MFA_platform

    The Mercedes-Benz MFA platform (Modular Front-Drive Architecture) is a car platform that produced by German automotive company Daimler AG. Intended for subcompact front-engine, front- and four-wheel drive applications, the first generation was produced from 2012 to 2019. An evolution of the platform, MFA2, has been in production since 2018.

  8. Material flow accounting - Wikipedia

    en.wikipedia.org/wiki/Material_flow_accounting

    In MFA studies for a region or on a national level the flows of materials between the natural environment and the economy are analyzed and quantified on a physical level. The focus may be on individual substances (e.g. Cadmium flows), specific materials, or bulk material flows (e.g. steel and steel scrap flows within an economy).
