Transmission electron microscopy and x-ray diffraction measurements reveal the presence of stacking faults ~SFs! in undoped cubic GaN thin layers. We demonstrate the importance of the defects in the interfacial region of the films by showing that the SFs act…

This paper analyzes inequality systems with an arbitrary number of proper lower semicontinuous convex
constraint functions and a closed convex constraint subset of a locally convex topological vector space.
More in detail, starting from well-known results on linear systems (with…

Cyclic voltammetry (CV) and Fourier transform infrared reflection-absorption spectroscopy (FT-IRRAS) have been combined to analyse the oxidation of methylamine and ethylamine on platinum single crystal electrodes in an acidic medium. The oxidation of both amines on Pt(hkl) electrodes gives rise…

We studied the phylogeny and systematics of the tribe Paragini (Diptera: Syrphidae) using morphological and molecular data. The paper presents separate parsimony analyses of both adult morphological characters and partial DNA sequence data from mitochondrial cytochrome c oxidase I and…

Endpiece to special issue of the Interconnections journal on sustainability: 'Perspectives on sustainability'.

Critical introduction to the special issue of the journal Women: a Cultural Review, written and edited by Maroula Joannou, Lucie Armitt and Paulina Palmer.

Abstract Discussions of conflict of interest (COI) in the university have tended to focus on financial interests in the context of medical research; much less attention has been given to COI in general or to the policies that seek to…

Oligogonotylus mayae n.sp. is described from the intestine of the Mayan cichlid Cichlasoma urophthalmus (Günther) in Ría Lagartos, Ría Celestún, and Estero Progreso, Yucatán State. This is the second species described for Oligogonotylus Watson, 1976, the other being O.manteri Watson,…

This book presents an approach based on Linux operating system, including issues such as kernel per se, units use and construction, different types of them, debugging techniques, as well as time management, interruptions, DMA (direct memory access), different buses and…

This text introduces comprehensively the reader to the distance teaching/learning process.
With this purpose, it presents a model of the Distance Education System to be used for understanding its embedded elements: contents, instructional design, communications, interaction, learning environment, and administration.
