Still others suggest that no salt at all is needed to properly lactoferment.
The dawn of the oil age was fairly recent. Although the stuff was used to waterproof boats in the Middle East 6,000 years ago, extracting it in earnest began only in 1859 after an oil strike in Pennsylvania.[…]It was used to make kerosene, the main fuel for artificial lighting after overfishing led to a shortage of whale blubber. Other liquids produced in the refining process, too unstable or smoky for lamplight, were burned or dumped.
If f(x)∈ Z [x], the ring of polynomials with coefficients in Z , then the content of f, denoted by c(f), is the greatest common divisor of the coefficients of f. The polynomial f(x) is called a primitive polynomial if c(f)=1. Since c(fg)=c(f)c(g), by Gauss's lemma [Hungerford, 74], the set S of primitive polynomials in Z [x] is a multiplicatively closed set. Define 𝛬= Z [x]_S, the localization of Z [x] at S, a subring of the field of quotients Q (x) of Z [x]. Elements of 𝛬 are of the form f(x)/g(x) with f(x),g(x)∈ Z [x] and g(x) a primitive polynomial.
Its financing pales next to the tens of billions that the Bill and Melinda Gates Foundation will have at its disposal, especially with the coming infusion of some $3 billion a year from Warren E. Buffett, the founder of Berkshire Hathaway.
