Mainstreaming Gender Into Project Cycle Management in the Fisheries Sector

This manual has been prepared to facilitate gender analysis and project planning in fisheries development projects. It is intended to be a toolkit to help project managers and implementing counterparts (such as extensionists, government and non-government field workers, and private- and public-sector development consultants, community organizers and leaders of local groups), to facilitate the integration of gender issues into the project cycle

Modeling Structure and Resilience of the Dark Network

While the statistical and resilience properties of the Internet are no more changing significantly across time, the Darknet, a network devoted to keep anonymous its traffic, still experiences rapid changes to improve the security of its users. Here, we study the structure of the Darknet and we find that its topology is rather peculiar, being characterized by non-homogenous distribution of connections -- typical of scale-free networks --, very short path lengths and high clustering -- typical of small-world networks -- and lack of a core of highly connected nodes. We propose a model to reproduce such features, demonstrating that the mechanisms used to improve cyber-security are responsible for the observed topology. Unexpectedly, we reveal that its peculiar structure makes the Darknet much more resilient than the Internet -- used as a benchmark for comparison at a descriptive level -- to random failures, targeted attacks and cascade failures, as a result of adaptive changes in response to the attempts of dismantling the network across time.Comment: 8 pages, 5 figure

Motif-based communities in complex networks

Community definitions usually focus on edges, inside and between the communities. However, the high density of edges within a community determines correlations between nodes going beyond nearest-neighbours, and which are indicated by the presence of motifs. We show how motifs can be used to define general classes of nodes, including communities, by extending the mathematical expression of Newman-Girvan modularity. We construct then a general framework and apply it to some synthetic and real networks

Systemic inflammation and residual viraemia in HIV-positive adults on protease inhibitor monotherapy: a cross-sectional study.

Increased levels of markers of systemic inflammation have been associated with serious non-AIDS events even in patients on fully suppressive antiretroviral therapy. We explored residual viremia and systemic inflammation markers in patients effectively treated with ritonavir-boosted protease inhibitor monotherapy (PImono)

Modelling diffusion of innovations in a social network

A new simple model of diffusion of innovations in a social network with upgrading costs is introduced. Agents are characterized by a single real variable, their technological level. According to local information agents decide whether to upgrade their level or not balancing their possible benefit with the upgrading cost. A critical point where technological avalanches display a power-law behavior is also found. This critical point is characterized by a macroscopic observable that turns out to optimize technological growth in the stationary state. Analytical results supporting our findings are found for the globally coupled case.Comment: 4 pages, 5 figures. Final version accepted in PR

Reducción cerrada y osteosíntesis con agujas percutáneas en las fracturas del radio distal

Se presentan 185 casos de fractura compleja del radio distal tratados con reducción ortopédica y estabilización con agujas de Kirschner introducidas de forma percutánea y asociadas a vendaje escayolado antebraquial. Los resultados funcionales finales fueron buenos o excelentes en 156 de los 185 casos (84,3%). Teniendo en cuenta los resultados, consideramos que el método es sencillo, útil y económico y debe valorarse su uso en la mayoría de las fracturas del radio distal.We report 185 cases of distal radius fractures treated by closed reduction and percutaneous Kirschner wire fixation. Final functional results were good or excellent in 156 of the 185 cases (84,3%). In view of the results, we think that the method is simple, useful and cheap, and must value its use in the majority of the distal radius fractures

Electrochemical corrosion and inhibition mechanisms of galvannealed steel

10 páginas, 11 figuras, 2 tablas.[ES] Se ha estudiado el mecanismo de corrosión de un acero galvanorrecocido, en 0,6 M de cloruro sódico, mediante espectroscopia de impedancia electroquímica. Los resultados revelan que el sistema, para tiempos mayores de 48 h de inmersión y hasta 1 mes en NaCl, está controlado por un proceso de difusión en capa finita. A su vez, se ha estudiado la efectividad de sales de cerio como inhibidor añadido en el medio agresivo, obteniéndose porcentajes de inhibición del 85% para concentraciones de 500 y 1.000 ppm a las 24 h de exposición. Además, los espectros de impedancia electroquímica revelan un cambio en el mecanismo de corrosión del galvanorrecocido por la adición del cerio en el medio.[EN] The corrosion mechanism of galvannealed in 0,6 M NaCl has been evaluated by means of electrochemical impedance spectroscopy (EIS). After 48 hours and for longer immersion time, up to 1 month, in sodium chloride, the system is controlled by a diffusion process at finite layer. Moreover, the effectiveness of cerium salts as inhibitor added in the electrolyte has been studied. Inhibition percentages of about 85% for 500 and 1000 ppm at 24 hours have been found. On the hand, changes in the corrosion mechanism due to the cerium presence were shown.Peer reviewe
