To facilitate differential diagnosis and screening of patients with a complaint of dizziness, we discussed in an earlier article1 a diagnostic classification system based on symptomatology and pathophysiology. This classification system included four subtypes of dizziness: vertigo, presyncope, dysequilibrium, and other dizziness. Many tests and measures that are needed for a full differential d...

General practice training schemes currently have no structured methods of assessment and most rely on a variety of subjective ratings of performance. In West Cumbria the ;objective structured clinical examination' has been used to assess training performance in areas covered by small group teaching during the preceding terms. Consultation skills, interpretation of clinical data and a number of ...

PURPOSE The aim of this study was to investigate the use and acceptance of digital radiographic examinations by Brazilian dental practitioners in daily practice and to evaluate the advances that have occurred over the past 5 years. MATERIALS AND METHODS Dental practitioners enrolled in extension courses at the Piracicaba Dental School, University of Campinas, Brazil, responded to a self-admin...

Bollobás, Erdős, and Szemerédi (1975) [1] investigated a tripartite generalization of the Zarankiewicz problem: what minimum degree forces graph with n vertices in each part to contain an octahedral K3(2)? They proved that n+2−1/2n3/4 suffices suggested it could be weakened n+cn1/2 for some constant c>0. In this note we show their method only gives n+(1+o(1))n11/12 provide many constructions if...

Supergravities are usually presented in a so-called 1.5 order formulation. Here we present a general scheme to derive pure 1 st order formulations of supergravities from the 1.5 order ones. The example of N4 = 1 supergravity will be rederived and new results for N4 = 2 and N11 = 1 will be presented. It seems that beyond four dimensions the auxiliary fields introduced to obtain first order formu...

We present efficient algorithms for broadcasting multiple messages. We assume n processors, one of which contains m packets that it must broadcast to each of the remaining n 1 processors. The processors communicate in rounds. In one round each processor is able to send one packet to any other processor and receive one packet from any other processor. We give a broadcasting algorithm which requi...
