Coteries may be used to construct permission based distributed mutual exclusion algorithms. One such algorithm is Maekawa's p N algorithm in which the co-terie is constructed based on nite projective planes. This paper presents a token based mutual exclusion algorithm which uses data structures similar to coter-ies, called quorum agreements. The performance(More)

BACKGROUND Direct immunofluorescence (DIF) is the gold standard in the diagnosis of immunobullous diseases. However, it cannot reliably differentiate various subtypes of subepidermal immune- bullous diseases (SIBD). Salt split technique (SST) could be used under such circumstances to differentiate them. There is paucity of reports in the Indian literature(More)
Epidermolysis bullosa acquisita (EBA) is an acquired subepidermal bullous disorder characterized by autoantibodies against Type VII collagen. It usually affects adults; childhood EBA is rare. We describe a 10-year-old girl presenting with recurrent tense blisters predominantly on legs, dorsa of hands and feet accompanied by oral erosions since the age of 5(More)
