Middle Spotted Woodpecker

The middle-spotted-woodpecker Dendrocopos medius, which was deemed to have disappeared from the littoral of Neuchâtel,is a species in full expansion today, particularly in the Bois du Devens (MULHAUSER & BLANT en prép.). Without differentiated silvicultural interventions-i.e. differentiated according to area-today this region would be dominated largely by the beech. The article presents the evolution of the forest Bois du Devens, the development of silvicultural practice during the 20th century and its effect on the expansion of the middlespotted-woodpecker. The analysis of the silviculture practised in this forest since 1920, fleshed out with the numerical basis of the silvicultural inventories, provides confirmation of the dependence of the middle-spotted-woodpecker on oaks of major dimensions, with a preference for highly fertile habitats and underlines the importance of mature forest stands. Such heterogeneous stands are rich in microstructures, cavity trees,big trees, trees that accomplish their full life cycle, as well as entire crowns that are left on the ground after trees have been cut.

Household electric blankets are widely used in China, but the problem of quality and safety is also more prominent, which is a serious threat to the health and safety of consumers. The structure characteristics and working principle of household electric blanket are analyzed. The hazards in the each stage of full life cycle are identified, including the stages of designing, manufacturing, packaging, transporting, utilizing and recycling. Hazard identification of each stage is made with methods of scenario analysis, safety check list, fault hypothesis analysis, hazard and operability analysis, failure mode and effect analysis and fault tree analysis, respectively.

Abstract Åström M., and Dekker W. 2007. When will the eel recover? A full life-cycle model. – ICES Journal of Marine Science, 64: 000–000: –. The European eel population has declined over the past decades in most of its distribution area, and the stock is outside safe biological limits. The EU has taken up the challenge to design a management system that ensures the escapement of 40% of spawning-stock biomass, relative to unexploited, unpolluted circumstances in unobstructed rivers. This ultimately aims to restore the spawning stock to a level at which glass eel production is not impaired, i.e. to restore to full historical glass eel recruitment. To explore the trajectory from the current depleted state to full recruitment recovery, we developed a simple model of stock dynamics, based on a simplified stock–recruitment relationship and the conventional dynamic pool assumptions. Recruitment trajectories under different future fishery regimes are explored, for the medium (one generation time) and long time-span (until full recruitment recovery). Reducing fisheries to zero, recovery is expected within ∼80 years, whereas under an ultimately sustainable fishing regime of just 10% of the current rate of fishing mortality, recovery may take more than 200 years. Moreover, management regimes, apparently leading to slight recovery of the stock in the coming 5–15 years, might still be unsustainable in the long run.

The Impact

The WindFloat prototype is a semisubmersible type foundation supporting a 2 MW, 3 bladed, horizontal axis Vestas V-80 turbine. The 8-year project is near its completion. After 3 years of planning, engineering and fabrication, the prototype was installed in 2011 in the northern Portugal Atlantic waters. Following 5 years of operations and electricity production, the unit was decommissioned in the summer of 2016. This paper retraces the prototype project going back to the early objectives, focusing on its 5-year performance and lessons learned. The overall assessment of the impact of the prototype on the incoming pre-commercial projects is discussed. Some emphasis is placed on both the decommissioning of the unit and the economics of the project, as these have not yet been published.

The Creation

Officially launched just over a year ago, the Open Access Network (OAN)offers a transformative, sustainable, and scalable model of open access(OA) publishing and preservation that encourages partnerships amongscholarly societies, research libraries, and other partners (e.g., academicpublishers, university presses, collaborative e-archives) who share acommon mission to support the creation and distribution of open researchand scholarship and to encourage more affordable education, which can be adirect outcome of OA publishing. Our ultimate goal is to develop acollective funding approach that is fair and open and that fully sustainsthe infrastructure needed to support the full life-cycle for communicationof the scholarly record, including new and evolving forms of researchoutput. Simply put, we intend to *Make Knowledge Public*.
