In general, John Aitchison defined compositional data to be proportions of some whole in 1982. [1] In particular, a compositional data point (or composition for short) can be represented by a real vector with positive components. The sample space of compositional data is a simplex: = {= [,, …,] | >, =,, …,; = =}.
Ballistic gelatin is traditionally a solution of gelatin powder in water. Ballistic gelatin closely simulates the density and viscosity of human and animal muscle tissue, and is used as a standardized medium for testing the terminal performance of firearms ammunition. While ballistic gelatin does not model the tensile strength of muscles or the ...
Gelatin is used as a binder in match heads [39] and sandpaper. [40] Cosmetics may contain a non-gelling variant of gelatin under the name hydrolyzed collagen (hydrolysate). Gelatin was first used as an external surface sizing for paper in 1337 and continued as a dominant sizing agent of all European papers through the mid-nineteenth century. [41]
Bloom is a test used to measure the strength of a gel, most commonly gelatin.The test was originally developed and patented in 1925 by Oscar T. Bloom. [1] The test determines the weight in grams needed by a specified plunger (normally with a diameter of 0.5 inch) to depress the surface of the gel by 4 mm without breaking it at a specified temperature. [2]
The closer this value is to 1.0, the better the data fit to a hyperplane representing the relationship between the response variable and a set of covariate variables. A value equal to 1.0 indicates all data fit perfectly within the hyperplane. λ: Gas mean free path (cm) D 50: Mass-median-diameter (MMD). The log-normal distribution mass median ...
Leaf protein concentrate (LPC) refers to the proteinaceous mass extracted from leaves. It can be a lucrative source of low-cost and sustainable protein for food as well as feed applications. It can be a lucrative source of low-cost and sustainable protein for food as well as feed applications.
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
Specific leaf area is a ratio indicating how much leaf area a plant builds with a given amount of leaf biomass: = where A is the area of a given leaf or all leaves of a plant, and M L is the dry mass of those leaves. Typical units are m 2 /kg or mm 2 /mg.
