Its implementation is a POSIX-compliant filesystem-level encryption layer, aiming to offer functionality similar to that of GnuPG at the operating system level, and has been part of the Linux kernel since version 2.6.19... |
https://en.wikipedia.org/wiki/Pho1%20family | The Pho1 phosphate permease family (TC# 2.A.94) is a family of phosphate transporters belonging to the ion transporter (IT) superfamily. Representative members of the Pho1 family include the putative phosphate transporter PHO1 of Arabidopsis thaliana (TC# 2.A.94.1.1), and the xenotropic and polytropic murine-leukemia v... |
https://en.wikipedia.org/wiki/Calcium%20sulfate | Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO4 and related hydrates. In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. It has many uses in in... |

https://en.wikipedia.org/wiki/FOIL%20method | In elementary algebra, FOIL is a mnemonic for the standard method of multiplying two binomials—hence the method may be referred to as the FOIL method. The word FOIL is an acronym for the four terms of the product:
First ("first" terms of each binomial are multiplied together)
Outer ("outside" terms are multiplied—tha... |
https://en.wikipedia.org/wiki/Runt | In a group of animals (usually a litter of animals born in multiple births), a runt is a member which is significantly smaller or weaker than the others.

https://en.wikipedia.org/wiki/New%20production | In biological oceanography, new production is supported by nutrient inputs from outside the euphotic zone, especially upwelling of nutrients from deep water, but also from terrestrial and atmosphere sources (as opposite to regenerated production, which is supported by recycling of nutrients in the euphotic zone). New p... |
