Using the example of smallholder oil palm production in Papua New Guinea the paper illustrates how elements of a market economy and modernity become enmeshed and partly transformed by local place-based nonmarket practices. The persistence, even efflorescence, of indigenous gift exchange in tandem with greater participation in the market economy challenges conventional notions regarding the stru...
[1] Thermodynamic equilibrium model calculations are used to show thatHNO3 can lower the relative humidity barrier to deliquesce binary ammoniated salts in the upper troposphere, particularly in aerosol solutions with an (NH4)2SO4 composition. Also in the case of (NH4)2SO4 or NH4HSO4 there is no abrupt change in the physical state of the thermodynamic system (instantaneous change of a dry salt ...
Magnesian limestone is a key construction component of many historic buildings that is under constant attack from environmental pollutants notably by oxides of sulfur via acid rain, particulate matter sulfate and gaseous SO(2) emissions. Hydrophobic surface coatings offer a potential route to protect existing stonework in cultural heritage sites, however, many available coatings act by blocking...
Reviewer #2 I have read the article “A Complete Parameterization of the Relative Humidity and Wavelength Dependence of the Refractive Index of Hygroscopic Inorganic Aerosol Particles” by the authors Cotterell et al. submitted to Atmos. Chem. Phys. Discuss. This paper provides the refractive indices for aerosol particles composed of salt and water using several atmospherically relevant salts as ...
