From Global Cities to Global Governors: Power, Politics, and the Convergence of Urban Climate Governance
… addresses the puzzling ability of the C40 Climate Leadership Group to achieve internal coherence. Leveraging a novel dataset of over 4700 discrete urban climate governance actions, I demonstrate empirically that the cities of the C40 have come not only to cohere around a common project, …

Efforts towards the Total Synthesis of Azaspiracid-3
… of azaspiracid-3.The C1-C21 domain and C22-C40 domain have been synthesized, which aims to assemble the molecule through Yamaguchi esterification. The ABCD domain involved an efficient NHK coupling reaction between C1-C12 segment and C13-C22 segment. The trioxadispiroketal skeleton was …

Organic Sulfur-Bearing Species as Subsurface Carbon Storage Vectors
… Sulfurized compounds including C20-28, C35 and C40 species were detected with double bond equivalent values suggesting the occurrence of sulfurized lipids. Laboratory sulfurization experiments on lipids yielded products with up to 7 sulfur atoms, which suggests labile biomolecules can be altered …

Las Relaciones Internacionales y un nuevo actor: las ciudades en el contexto del cambio climático
… más importantes a nivel internacional (ICLEI y C40) y una red local RAMCC. donde se expondrán cualidades de las ciudades que las ubica en el sistema internacional. Nuestro argumento es que la disciplina está mutando y sigue en ese proceso. Una disciplina marcada y liderada por los estados …

Biogeochemical applications of compound-specific radiocarbon analysis
… and diols, sterols, hopanols, and ether-linked C40-biphytanes of Archaea. The data show that the carbon source for most of the biomarkers is marine euphotic zone primary production or subsequent heterotrophic consumption of this biomass. Two lipid classes represent exceptions to this finding. …

Volatility properties of the ambient and laboratory generated aerosol
… the saturation vapor of the N-alkanes (C12 - C40), and carboxylic acids using measurement of gas-particles partitioning of these compounds in ambient aerosols. For normal alkanes with molecular weight between 275 - 375 g/mol, most of the estimated values were very close (within 20 %) to …

Sea + Survival: choreographing dune systems to defend against sea-level rise
… impacts of rising seas and storm surges (C40 Cities, n.d.). In particular, coastal towns and cities are under immense pressure as major solutions are needed to ensure the resilience of these spaces. Langebaan, in the Greater Saldanha Region along the Western Cape, South Africa is suffering …

Mass spectrometric studies of ether lipids in Archaea and sediments
… from individual losses of both ring-containing C40 alkyl chains, allowing the reported structures to be verified with respect to the distribution of the rings within the two chains. A number of additional, hitherto unreported isomers and higher homologues of the ring-containing structures were …

Unravelling the impacts of palaeoecology, palaeoenvironment and lithofacies on sedimentary organic NSO compounds
… biomolecules via sulfurization, such as C40 carotenoids, C35 bacteriohopanepolyols, C30 unsaturated tetracyclic polyprenoid alcohols, C30 or C25 highly branched isoprenoid (HBI) polyenes. The strong enrichment of sulfurized C35 bacteriohopanepolyols can be developed as an indicator of the …

Characterisation of waxy gas-condensates by high temperature capillary gas chromatography and oxidative degradation
… CC) discriminated against HMW compounds above C40 whereas adsorption onto alumina in a warm cyclohexane slurry provided an aliphatic fraction still rich in HMW compounds and suitable as a biodegradation substrate. A waxy Indonesian oil was subjected to 136 day biodegradation by Pseudomonas …
