Twelve patients with dextro-transposition of the great vessels (age eight months to four years) were studied by echocardiography following Mustard's procedure. Nine of them had also been studied preoperatively. Postoperatively all patients demonstrated structural echoes in the atrial cavity behind the pulmonary root. In ten, the motion pattern generally resembled that of a stenotic atrioventric...

Colonization of the south-western European mountain ranges is suggested to have predominantly progressed from the Iberian Peninsula eastwards, but this hypothesis has never been tested in a statistical framework. Here, we test this hypothesis using Androsace vitaliana, a high elevation species with eight mostly allopatric subspecies, which is widely but disjunctly distributed across all major s...

This essay addresses the methodology of philosophy of science and illustrates how formal and empirical methods can be fruitfully combined. Special emphasis is given to the application of experimental methods to confirmation theory and to recent work on the conjunction fallacy, a key topic in the rationality debate arising from research in cognitive psychology. Several other issue can be studied...

A new agricultural flood losses prediction method using digital elevation data combined with agricultural economic data is presented. The method is based on dynamically simulating the procedure of flood out. An example in Huangdunhu flood detention area, Jiangshu province of China has been given to describe how to use it to predict the incoming agricultural losses. Compared with prior methods, ...

where p is prime. In our paper we use the latter name. In this form numbers Mp at the first time were studied by Marin Mersenne (1588-1648) at least in 1644 (see in [1, p.9] and a large bibliography there). In our paper we show that all composite Mersenne numbers belong to a class S of pseudoprimes of base 2 which is a subclass of super-Poulet pseudoprimes. Analysis of properties of pseudoprime...

Pachylaelaps (Pachylaelaps) pyrenaicus sp. n. and Pachylaelaps (Longipachylaelaps) brevipilis sp. n. (Acari, Pachylaelapidae) are described and illustrated based on specimens from litter and soil detritus of forest habitats in Spain (Pyrenees Mts) and Portugal (Serra da Labruja Mts), respectively. An identification key to European species of the genus Pachylaelaps Berlese, 1888 is provided.

The Alboran Basin and the surrounding Betic-Rif Cordilleras (see Fig. 1) constitute an arc-shaped thrust-belt that exempli®es contemporaneous internal extension and frontal thrusting in an overall compressional setting. The complex tectonic evolution of the region is the result of ongoing convergence between Africa and Eurasia since late Mesozoic. Until the amalgamation of Iberia with Europe, f...
