The breast can be diffusely affected by a variety of specifi c and unique disorders, including benign disorders that are closely related to physiologic changes and infl ammatory and infectious diseases, as well as by benign and malignant tumors. The clinical manifestations include unilateral or bilateral breast enlargement with/without a palpable masses, shrinkage and breast asymmetry. Thus, kn...

To show the impact of sensor behaviour on the control result, four strategies for aeration control are tested using different sensor characteristics. It is demonstrated, on the one hand, how an increasing response time will limit the achievable control quality and, on the other hand, how a given sensor characteristic can be taken into account for the controller design. The presented tests show ...

Primary hyperaldosteronism is described in a 27-year-old Brazilian woman from an endemic area of schistosomiasis. She presented with hypokalaemia, cramps and polyuria, refractory hypertension, plasma aldosterone of 40.7 ng/dL and aldosterone/renin activity ratio higher than 100, due to an associated long-standing unsuspected aldosteronoma. Computed tomography showed a well-defined ovoid right a...

(This can be shown using a basis argument, which would amount to what most of you wrote anyway.) Thus, given S ∈ L(V ) such that imS ⊆ imT , we can define R = (T |W )−1S, from which it follows TR = S. Conversely, if S = TR, then since linear operators preserve inclusion and R(V ) ⊆ V , we have S(V ) = (TR)(V ) ⊆ T (V ); that is, imS ⊆ imT . 2. Let T be a linear operator on V with distinct eigen...

Objective: The aim of this study was to identify factors related to the prevalence of caries in 12-year-old schoolchildren. Methods: A cross-sectional study was carried out using a representative sample (n = 1217) of the population of 12-yearold schoolchildren in Galiza (northwest Spain). Independent variables were measured through a questionnaire, and dependent variables were determined throug...
