12Medium density polyethylene — Medium Density Polyethylene, or MDPE is a type of Polyethylene defined by a density range of 0.926 0.940 g/cm3. It is less dense than HDPE, which is more common.MDPE can be produced by chromium/silica catalysts, Ziegler Natta catalysts or… …
13Low-density polyethylene — LDPE has SPI resin ID code 4 Low density polyethylene (LDPE) is a thermoplastic made from petroleum. It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via free radical… …
14Free range — is a method of farming husbandry where the animals are allowed to roam freely instead of being contained in any manner. The term is used in two senses that do not overlap completely: as a farmer centric description of husbandry methods, and as a… …
15Kernel density estimation — of 100 normally distributed random numbers using different smoothing bandwidths. In statistics, kernel density estimation is a non parametric way of estimating the probability density function of a random variable. Kernel density estimation is a… …
16Home range — is a concept that can be traced back to a publication in 1943 by W. H. Burt, [Burt, W. H. 1943. Territoriality and home range concepts as applied to mammals. Journal of Mammalogy 24:346–352.] who constructed maps delineating the spatial extent or …
17Free-range eggs — The main difference between free range and factory farmed eggs is that the birds are permitted to roam freely within the farmyard and only kept in sheds or henhouses at night. However, not all countries have legal standards defining what free… …
18Dynamic range — For other uses, see Dynamic range (disambiguation). Dynamic range, abbreviated DR or DNR,[1] is the ratio between the largest and smallest possible values of a changeable quantity, such as in sound and light. It is measured as a ratio, or as a… …
19Electronic density — In quantum mechanics, and in particular quantum chemistry, the electronic density is a probabilistic measure of the number of electrons occupying a given element of space. It is a scalar quantity depending upon three spatial variables and is… …
