Polarity Notes - Embrace Challenge
... Polarity is responsible for many behaviors you see happening in nature. One main concept is that “Like dissolves like.” For example, salt dissolves in water because it is charged and water is polar (has an imbalance of its charge.) Things with charges on them can dissolve in water. Oil, on the other ...

CHAPTER 1 PATHOGENESIS OF GOUSIEKTE 1.1

It belongs to the polyamine group and is similar to spermidine, spermine and putrescine (Bode et al., 2010). Th ...
