The structure of the title compound, C7H4OS4, at 100 K has ortho-rhom-bic symmetry. In the crystal, tetra-thia-fulvalene mol-ecules form π-stacks along the a axis, with a stacking distance of 3.4736 (6) Å. Along the b axis, parallel stacks are inter-connected with each other through a network of weak C-H⋯O hydrogen bonds and short S⋯S contacts [3.4813 (7) Å]. Additional short S⋯S contacts [3.49...
The asymmetric unit of the title compound, C(8)H(14)N(6)O(2), contains two independent mol-ecules. In one mol-ecule, the amide-substituted N atoms of the tetra-zine ring deviate from the plane [maximum deviation = 0.028 (1) Å] through the four other atoms in the ring by 0.350 (2) and 0.344 (2) Å, forming a boat conformation, and the mean planes of the two carboxamide groups form dihedral angles...
Following a brief survey of the historic development of pneuma tic prostheses the actual principles of prosthetic management in bi lateral shoulder disarticulation or bilateral amelia are explained. The active functions are re stricted to active pronation and supination, active gripping of the terminal device "hook" or "hand", combined with pneumatic locking of free swinging shoulder and elb...
The purpose of the present study was to examine the impact of the congenital absence of one hand on cortical organization of the sensorimotor cortex (S1/M1). We investigated the tongue representation in S1/M1 in nine participants with normally developed limbs, comprising the control group, and in eight persons with a congenitally completely missing hand (i.e. unilateral hand amelia). All partic...
