Within the Flexnode Plus project the long-term degradation characteristics of a proton exchange membrane (PEM) electrolyzer (5.5 kW, AC, 1 Nm3/h H2) and fuel cell (1.0 kW, DC, 0.9 Nm3/h) was experimentally tested. The electrolyzer unit was operated at various loads and pressures for approximately 750 …

Tropical forests are under serious pressure and deforestation and forest degradation are taking their toll. The mixed dipterocarp forests of Sarawak are no exception. The importance of sustainable forest management is evident and growth models are a convenient tool to help in determining sustainable …

The majority of houses in the Groningen gas field region, the largest in Europe, consist of unreinforced masonry material. Because of their particular characteristics (cavity walls of different material, large openings, limited bearing walls in one direction, etc.) these houses are exceptionally vulnerable …

Sharks are ecological important inhabitants of most of the world’s oceans and seas. Still their life-history, which is dictated by slow growth rates and late maturity, makes most species, especially demersal- and coastal sharks, prone to exploitation through target- and nontarget fisheries. Another threat …

Coral reefs are one of the most important ecosystems in the world, in terms of both biological diversity and economy. These ecosystems are under a great amount of threats (e.g. climate change, pollution, coastal development and overfishing), which can lead to reef degradation and decrease of three-dimensional …

This paper utilises a methodology named “Risk SituatiOn Awareness Provision” (RiskSOAP). RiskSOAP expresses the capability of a system to meet its safety objectives by controlling its processes and communicating threats and vulnerabilities to increase the situation awareness of its end-users and support …

Background: Pseudomonas aeruginosa is a nosocomial pathogen that causes severe infections in immunocompromised patients. Biofilm plays a significant role in the resistance of this bacterium and complicates the treatment of its infections. In this study, the effect of lyticase and β-glucosidase enzymes …

Analysis of spontaneous speech is an important tool for clinical linguists to diagnose various types of neurodegenerative disease that affect the language processing areas. Prosody, fluency and voice quality may be affected in individuals with Parkinson's disease (PD, degradation of voice quality, unstable …

Bankrupting Nature: Denying our Planetary Boundaries by Andres Wijkman and Johan Rockström emerges from the original report of The Club of Rome’s The Limits to Growth authored by Meadows and colleagues in 1972. This book demonstrates that an economy built on the …

Forests, both natural and planted, can provide multiple benefits to human society. The loss of these ecosystem services due to deforestation and forest degradation is of global concern and of particular importance to rural populations that rely on natural resources for their livelihoods. One of the (international) …
