TL;DR: This article explored the iconography of climate change in contemporary climate action campaigns in the UK and showed how sample images are simultaneously scientific denotations of global warming and cultural connotations of danger and vulnerability.
Abstract: This paper explores the iconography of climate change in contemporary climate action campaigns in the UK. I aim to show how sample images are simultaneously scientific denotations of global warming and cultural connotations of danger and vulnerability. I further demonstrate that while similar images are associated with different agendas and geographical visions, they attach to a shared discourse of vulnerability that has Western (colonial) roots. The paper concludes with an overview of possible ways for climate action campaigns to effectively convey their political messages without recycling colonial visions of the world.

TL;DR: Supramolecular assemblies of 1,2,4,5-benzenetetracarboxylic acid, 1, with aza donor molecules, have been synthesized and characterized by single-crystal X-ray diffraction methods and divide into two classes, host-guest systems and assemblies with infinite molecular tapes.
Abstract: Supramolecular assemblies of 1,2,4,5-benzenetetracarboxylic acid, 1, with aza donor molecules such as 1,10-phenanthroline, 2, 1,7-phenanthroline, 3, phenazine, 4, 4-(N,N-dimethylamino)pyridine, 5, 1,2-bis(4-pyridyl)ethene, 6, and 1,2-bis(4-pyridyl)ethane, 7, have been synthesized and characterized by single-crystal X-ray diffraction methods. All the complexes crystallize in the triclinic, P1 space group. In the complexes of 2 and 4, water is also present in the resultant assembly, but the complexes of 5, 6, and 7 crystallize without any water molecules or solvent of crystallization. However, 3 forms two types of complexes, a hydrate and a nonhydrate complex, depending upon whether water is used as a solvent or not. These assemblies divide into two classes, host−guest systems (with aza molecules being in the channels created by the acid molecules) and assemblies with infinite molecular tapes. While the assemblies of the compounds 2, 4, and 5 belong to the former class, the assemblies of compounds 6 and 7 ...

TL;DR: In this paper, the condensation reaction of 4-oxo-(4H)-1-benzopyran-3-carbaldehydes and of aromatic aldehydes with 3-methyl-1-phenylpyrazolin-5-4H-one were carried out in an ionic liquid, ethylammonium nitrate, at room temperature in shorter times with higher yields of 78−92 and 70−75%, respectively, than found using conventional procedures.

TL;DR: In this article, the authors report on a study to assess the capabilities of the recently launched remote sensing satellite sensor Ikonos, with improved capabilities, for mapping and monitoring upland vegetation using traditional image classification methods.
Abstract: Aim Traditional methodologies of mapping vegetation, as carried out by ecologists, consist primarily of field surveying or mapping from aerial photography. Previous applications of satellite imagery for this task (e.g. Landsat TM and SPOT HRV) have been unsuccessful, as such imagery proved to have insufficient spatial resolution for mapping vegetation. This paper reports on a study to assess the capabilities of the recently launched remote sensing satellite sensor Ikonos, with improved capabilities, for mapping and monitoring upland vegetation using traditional image classification methods.
Location The location is Northumberland National Park, UK.
Methods Traditional remote sensing classification methodologies were applied to the Ikonos data and the outputs compared to ground data sets. This enabled an assessment of the value of the improved spatial resolution of satellite imagery for mapping upland vegetation. Post-classification methods were applied to remove noise and misclassified pixels and to create maps that were more in keeping with the information requirements of the NNPA for current management processes.
Results The approach adopted herein for quick and inexpensive land cover mapping was found to be capable of higher accuracy than achieved with previous approaches, highlighting the benefits of remote sensing for providing land cover maps.
Main conclusions Ikonos imagery proved to be a useful tool for mapping upland vegetation across large areas and at fine spatial resolution, providing accuracies comparable to traditional mapping methods of ground surveys and aerial photography.
