چکیده
We present a construction method of BIB-designs from a finite group G and a group of automorphisms Φ on G such that |Φ(x)| = |Φ| for all x ∈ G, x = 0. By using a generalization of the concept of a difference family we can so unify several previous constructions of BIB-designs from planar near-rings.

متن کاملLetrozole and norethisterone acetate versus letrozole and triptorelin in the treatment of endometriosis related pain symptoms: a randomized controlled trial
BACKGROUND When aromatase inhibitors are used to treat premenopausal women with endometriosis, additional drugs should be used to effectively down-regulate gonadal estrogen biosynthesis. This randomized prospective open-label study compared the efficacy in treating pain symptoms and the tolerability of letrozole combined with either norethisterone acetate or triptorelin. METHODS Women with pa...
