We describe some recent development on the theory of formal Frobenius manifolds via a construction from differential Gerstenhaber-BatalinVilkovisk (DGBV) algebras and formulate a version of mirror symmetry conjecture: the extended deformation problems of the complex structure and the Poisson structure are described by two DGBV algebras; mirror symmetry is interpreted in term of the invariance o...

The differential diagnoses for acid-base problems can be reduced to a workable few by using a minimal amount of laboratory data. Following well-established principles and formulas, the presenter will help you resolve common acidbase problem cases. • Identify etiologies of anion gap and non-anion gap acidosis. • Explain the principle of osmolar gap. • Differentiate the causes of acid-base distur...

A case of lipoma of the floor of the mouth presenting as an acute swelling in a 72-year-old man is reported. The clinical presentation and differential diagnosis are discussed.

There is a group of diseases characterized by inflammatory nodules which generally located on the lower leg. They have certain clinical appearances in common, which often makes a differential diagnosis difficult or impossible on clinical grounds alone. There is a great variation in histopathologic appearance, which depends on the duration of the lesions and sites from specimens are obtained for...

This chapter will be structured in the following manner. A specifi c histological term that may provide a diagnostic clue will be precisely defi ned. Along with the histological defi nition, the clinical correlate will be described so that there is the beginning of the essential clinicopathologic correlation that is always necessary in order to make the best possible diagnosis. After presenting...

OBJECTIVES the objective of this study was to evaluate the items contained in the Brazilian version of the Power as Knowing Participation in Change Tool (PKPCT). METHOD investigation of the psychometric properties of the mentioned questionnaire through Rasch analysis. RESULTS the data from 952 nursing assistants and 627 baccalaureate nurses were analyzed (average age 44.1 (SD=9.5); 13.0% me...

This paper discusses the issue of differential item functioning (DIF) in international surveys. DIF is likely to occur in international surveys. What is needed is a statistical approach that takes DIF into account, while at the same time allowing for meaningful comparisons between countries. Some existing approaches are discussed and an alternative is provided. The core of this alternative appr...

We show how to find all the integrating factors and corresponding first integrals for any system of Ordinary Differential Equations (ODEs). Integrating factors are shown to be all solutions of both the adjoint system of the linearised system of ordinary differential equations and a system that represents an extra adjoint-invariance condition. We present an explicit construction formula to find ...

OBJECTIVES The main objective of this study is to learn more on the image use and search requirements of radiologists. These requirements will then be taken into account to develop a new search system for images and associated meta data search in the Khresmoi project. METHODS Observations of the radiology workflow, case discussions and a literature review were performed to construct a survey ...
