The support of a set A is the crisp subset of A with nonzero membership grades. Similarly, the core of a set A is the crisp subset of A with membership grade equal to one. So, supp(A) = {x|μA(x) > 0} and core(A) = {x|μA(x) = 1}. (1.1.4) The α-cut Aα of a set A is the crisp subset of A with membership grades of at least α. So, Aα = α-cut(A) = {x|μA(x) ≥ α}. (1.1.5) Note that core(A) = 1-cut(A). ...

The uptake of formalin-denaturated homologous albumin (FDA) by rat liver sinus-lining cells was studied using ultrastructural, cytochemical, and immunocytochemical techniques. Three minutes after intravenous injection of: 1) FDA, 2) peroxidase-coupled FDA (HRP-FDA), 3) ferritin-labeled FDA (FE-FDA), 4) colloidal gold-labeled FDA (CG-FDA), or 5) 0.85% NaCl, livers were fixed by perfusion with tw...
