... maintained by 2.5% sevofluran. Normoglycemia was confirmed by determining blood glucose content (plasma glucose concentration 4.4 to 7.6 mM). The animal experiments were approved by the local ... constant determined by the ratio between B max and K d . Therefore, BP can be altered without any change in receptor affinity (K d ). By contrast, B max can be affected by several f...

The notched cube (see Figure 1) has already been shown by Stein [St] to tile R d by a lattice (Conlan [Con] has done this ... notched cube, which is a very explicit function (see (11)). We find all the tilings discovered by Stein, which, by a deeper theorem of Schmerl [Sch], is the complete list of possible tran...

Alternatively, multiplying the recursive formula (3) by x n−1 /(n − 1)! and summing over n ≥ 1 yields d dx F 112 (x; k) = F 112 (x; k) + (1 + x) d dx F 112 (x; k − 1). Multiplying this...
