Methane is one of the important greenhouse gases and plays an important role in atmospheric chemistry. Its contribution to the current greenhouse effect is about 22%. Since the beginning of the industrialization the atmospheric methane concentration has increased by a factor of 2.5. This increase continues until present, however, since the early 1990s the growth rate has decreased. Superimposed...

For the hydrogen oxidation reaction (HOR), platinum group metal (PGM) catalysts are still norm, and their large initial catalytic activity is counterbalanced by uncertain durability in alkaline environments: harsh degradations proceed, like detachment agglomeration of metallic nanoparticles from carbon support, as witnessed dedicated accelerated stress tests (AST). Herein, a strategy to increas...

INTRODUCTION Methane is a highly efficient greenhouse gas, approximately 21 times more effective than CO2 at trapping infrared radiation from Earth (Seinfeld and Pandis, 2006). Although the importance of methane in the climate system is recognized, its global budget is poorly constrained. The atmospheric reservoir is easily estimated using measured methane concentrations; residence time and pri...

Wetlands are the world’s largest natural source of methane, a powerful greenhouse gas. The strong sensitivity of methane emissions to environmental factors such as soil temperature and moisture has led to concerns about potential positive feedbacks to climate change. This risk is particularly relevant at high latitudes, which have experienced pronounced warming and where thawing permafrost coul...

KLEMAS, V., 2011. Remote sensing of wetlands: case studies comparing practical techniques. Journal of Coastal Research, 27(3), 418–427. West Palm Beach (Florida), ISSN 0749-0208. To plan for wetland protection and sensible coastal development, scientists and managers need to monitor the changes in coastal wetlands as the sea level continues to rise and the coastal population keeps expanding. Ad...

Wetland species identification is a very important process when determining wetland ecosystem types and wetland composition. Hyperspectral data with the merit of high spectral resolution have become a powerful tool for ground feature identification compared with multi-spectral data. This paper investigated the hyperspectral characters of wetland plants by considering the two prominent attribute...

Bu araştırmanın amacı, sınıf öğretmenlerinin bireysel yılmazlıkları ve akademik iyimserlikleri arasındaki ilişkinin incelenmesidir. Çalışma, ilişkisel tarama modeli kullanılarak gerçekleştirilmiştir. Araştırmanın örneklemini tesadüfi örnekleme yöntemiyle seçilen 350 öğretmeni oluşturmaktadır. Araştırmada veri toplama araçları olarak “Yetişkin Yılmazlık Ölçeği” “Akademik İyimserlik kullanılmıştı...

Evaluating the significance of protected areas for biodiversity and ecosystem services is important for nature conservation. In a recent issue of PNAS, Xu et al. (1) present valuable information on provision of biodiversity and ecosystem services by China’s nature reserves. They conclude that reserves serve bird populations moderately well. However, the importance of coastal wetlands for migrat...
