Finite End Intervals in Definable Quotients of ,,It will be shown that in a factor lattice of the lattice of c.e. sets under inclusion with respect to a special congruence relation, there exists a finite end interval which is not a Boolean algebra.

Measuring Crustal Stress: Core-Based Methodsto arithmetical numberings. We prove that principal numberings are complete; completeness is independent of the oracle; the degree of any incomplete numbering is meet-reducible, uniformly complete numberings exist. We completely characterize which finite arithmetical families have a universal number

Stress Fractures of the Pelvis and Sacrumbraic properties; the elementary theory of any Rogers semilattice at arithmetical level . ≥ 2 is hereditarily undecidable; the class of all Rogers semilattices of a fixed level . ≥ 2 has an incomplete theory.
