The paper deals with sets of distributions which are given by moment conditions for the distributions and convex constraints on derivatives of their c d fs A general albeit simple method for the study of their extremal struc ture extremal decomposition and topological or measure theoretical proper ties is developed Its power is demonstrated by the application to bell shaped distributions Extrem...

1. Chapter 4, §1: 2. Suppose that F is a field and that a and b are in F. Suppose that a · b = 0, and that b = 0. Let c be the inverse of b. Multiplying the equation above by c on the left, we get 0 = 0 · c = (a · b) · c = a · (b · c) = a · 1 = a. Thus a = 0. It follows that F is an integral domain. 8. We compute a b c d 1 0 0 0 = a 0 c 0 , and 1 0 0 0 a b c d = a b 0 0. If we have equality, th...

    Background: Giant cell tumor (GCT) of the bone is a benign neoplasm with local aggressive behavior. Distal ulna is a very rare place for GCT. Published studies have mainly focused on case reports, and thus there is no consistent treatment strategy for this tumor at this location. This retrospective study was conducted to evaluate the oncological and functional results of 2 di...

One hundred and twenty cytological smears and 106 histological specimens were obtained from 115 patients using a new technique of endometrial sampling. It proved an atraumatic procedure and was well accepted by the patients. Some problems were encountered in the preparation of satisfactory cytological specimens and in their interpretation. The method was not completely reliable for detecting en...
