Stemming from the study of signals via wavelet coefficients, the spaces S\nu are complete metrizable and separable topological vector spaces, parametrized by a function \nu, whose elements are sequences indexed by a binary tree. Several papers were devoted to their basic topology; recently it was also shown that depending on \nu, S\nu may be locally convex, locally p-convex for some p > 0, or not at all, but under a minor condition they are always pseudoconvex. We tackle here some more sophisticated properties: their diametral dimensions show that they are Schwartz but not nuclear spaces. Moreover, Ligaud’s example of a Schwartz pseudoconvex non p-convex space is actually a particular case of S\nu. [less ▲]

A relationship between disaccharidase and diamine oxidase (DAO) activities was looked for by measuring these enzyme activities in histologically normal small intestinal biopsies of 18 children. The range for disaccharidase activities expressed in U g-1 wet weight was 0.1-5.7, 7.1-36.7, and 2.3-8.5 for lactase, maltase, and sucrase, respectively. The range for DAO activities expressed in nmol h-1 g-1 wet weight was 202-974. Significant correlations were found between disaccharidase and DAO activities (lactase versus DAO: n = 17, r = 0.80, P < 0.001; maltase versus DAO: n = 18, r = 0.70, P < 0.001; sucrase versus DAO: n = 18, r = 0.55, P < 0.05). Our results further support the hypothesis that DAO is a marker of small intestinal functional integrity in children. [less ▲]

In recent years, phase mask coronagraphy has become increasingly efficient in imaging the close environment of stars, enabling the search for exoplanets and circumstellar disks. Coronagraphs are ideally suited instruments, characterized by high dynamic range imaging capabilities, while preserving a small inner working angle. The AGPM (Annular Groove Phase Mask, Mawet et al. 20051) consists of a vector vortex induced by a rotationally symmetric subwavelength grating. This technique constitutes an almost unique solution to the achromatization at longer wavelengths (mid-infrared). For this reason, we have specially conceived a mid-infrared AGPM coronagraph for the forthcoming upgrade of VISIR, the mid-IR imager and spectrograph on the VLT at ESO (Paranal), in collaboration with members of the VISIR consortium. The implementation phase of the VISIR Upgrade Project is foreseen for May-August 2012, and the AGPM installed will cover the 11-13.2 μm spectral range. In this paper, we present the entire fabrication process of our AGPM imprinted on a diamond substrate. Diamond is an ideal material for mid-infrared wavelengths owing to its high transparency, small dispersion, extremely low thermal expansion and outstanding mechanical and chemical properties. The design process has been performed with an algorithm based on the rigorous coupled wave analysis (RCWA), and the micro-fabrication has been carried out using nano-imprint lithography and reactive ion etching. A precise grating profile metrology has also been conducted using cleaving techniques. Finally, we show the deposit of fiducials (i.e. centering marks) with Aerosol Jet Printing (AJP). We conclude with the ultimate coronagraph expected performances. [less ▲]

Purpose of review The purpose of this review is to update the knowledge on diarrhoea, a common problem in critically ill patients. Epidemiological data will be discussed, with special emphasis on diarrhoea in tube-fed patients and during antibiotic therapy. The possible preventive and therapeutic measures will be presented. Recent findings The need for concise definitions of diarrhoea was recently re-emphasized. The use of pump-driven continuous instead of intermittent enteral feeding is less often associated with diarrhoea. The discontinuation of enteral feeding during diarrhoea is not justified. Clostridium difficile-associated diarrhoea is frequent during antibiotic therapy with quinolones and cephalosporins. Formulas enriched with water-soluble fibres are probably effective to prevent diarrhoea, and promising data on the modulation of gut microflora with probiotics and prebiotics were recently released. Summary Diarrhoea is common in critically ill patients, especially when sepsis and hypoalbuminaemia are present, and during enteral feeding and antibiotic therapy. The management of diarrhoea includes generous hydration, compensation for the loss of electrolytes, antidiarrheal oral medications, the continuation of enteral feeding, and metronidazole or glycopeptides in the case of moderate to severe C. difficile colitis. The place of enteral formulas enriched with water-soluble fibres, probiotics and prebiotics is not yet fully defined. [less ▲]

In control rabbits, a renal ischemia of 60 min followed by 10 min of reperfusion resulted in an enhanced free radical production in cortical tissue, as assessed by a significant decrease of free glutathione (42%), protein-bound GSH (17%), and vitamin E (49%). In contrast, catalase or glutathione peroxidase activities were not affected by these experimental conditions. Free radical production in this model was also measured directly using electron spin resonance (ESR) spectroscopy associated with a PBN (alpha-phenyl N-tert-butyl-nitrone) spin trap agent in the venous blood arising from the ischemic kidney. The signal consisted of a triplet of doublets. In contrast, no signal could be detected in control blood samples taken prior to inducing ischemia. The burst of free radical production occurred in the early phase after restoration of flow in the kidneys rendered ischemic, as evidenced by a signal of weak intensity which generally appeared within the third minute after reperfusion and progressively increased to form a well-defined asymmetric signal following 10 min of reperfusion. The precise nature of free radicals trapped by the PBN agent remains, however, to be elucidated, but analysis of the coupling constants (aN = 14.5-15 G; a beta H = 2.5-3 G) and asymmetry of the central doublets suggests that the ESR signal may arise from a nitorxy-radical adduct resulting from the spin trapping by PBN of both oxygen- or carbon-centered radicals of lipid origin. As evidenced by both direct and indirect measurements, exchange of rabbit blood immediately after inducing renal ischemia with 30 ml/kg of Diaspirin Crosslinked Hemoglobin (7.5 g/dl in lactated electrolyte) or human serum albumin (7.5 g/dl in lactated electrolyte) did not exacerbate free radical production mediated by an ischemia reperfusion phenomenon, a typical situation found in a resuscitation setting.

This paper focuses on the external vote and wider transnational political participation of Andean migrants from Colombia and Bolivia. Its main aim is to discuss the contributions of these diasporas to democratic and wider political processes in the home countries. The two cases considered offer a good opportunity to do so, since in the last few decades they have put forward new mechanisms for the political inclusion of their nationals abroad, but in different historical, socioeconomic and political contexts. Key amongst these initiatives has been the extension of voting rights to nationals abroad. One of the objectives is thus to compare the different reasons and mechanisms used by states to implement external voting policies, as well as migrant participation in elections. Migrants from the three countries have participated to a lesser or greater degree in the development of such policies and the practice of voting from abroad. A comparison of their participation rates in each case and the reasons for voting or not might allow us to find out more about the success or failure of such processes. Equally, different governments, parties and other state and political institutions in the home countries have related differently to the diasporas, often based on the supposed political allegiances or ideological inclinations of these groups. Based on all this, the two national communities abroad studied have played different roles in key recent political processes in their home countries, such as the emergence of an ethno- nationalist-left government in Bolivia, and efforts for greater democracy and the end of the armed conflict in Colombia. This paper is based on quantitative and qualitative data, as well as secondary information, obtained by the authors through different research projects carried out over the last few years with migrants from the two countries studied. The text looks next at the theoretical framework for the research, before analysing in detail the two cases considered. The last develops a comparative discussion and presents concluding perspectives. [less ▲]

A nivel internacional, 115 países permiten que sus ciudadanos en el exterior ejerzan el derecho de participar en las elecciones de su país de origen. A pesar del desarrollo de la literatura sobre transnacionalismo político, el impacto del voto en el exterior sobre las relaciones entre emigrante, país de origen y país de residencia permanece desconocido. A través del caso de las elecciones presidenciales bolivianas del 6 de diciembre 2009, este libro discute las motivaciones de los estados expulsores por otorgar el derecho de votar a sus emigrantes, las variaciones en el uso de este derecho por los emigrantes según los lugares de destino y el impacto de este voto sobre el empoderamiento de los emigrantes en las sociedades de origen y de residencia. Los resultados presentados en este libro se basan en la observación del proceso electoral en el exterior, en entrevistas en profundidad conducidas con emigrantes y en más de 300 encuestas con electores bolivianos realizadas en las ciudades de Madrid, Buenos Aires, San Pablo y Nueva York.
