Small-angle X-ray scattering (SAXS) is used to demonstrate the presence of density fluctuations in ambient water on a physical length-scale of approximately 1 nm; this is retained with decreasing temperature while the magnitude is enhanced. In contrast, the magnitude of fluctuations in a normal liquid, such as CCl(4), exhibits no enhancement with decreasing temperature, as is also the case for ...

Water cooling by ambient takes place with two mechanisms of heat and mass transfer. Using packings at wet cooling towers has disadvantages such as obstruction, reduction of life expectancy and production of algae and fungi. In shower cooling towers types of towers packings are completely removed and water intake is in direct contact and heat transfer takes place in two ways of latent and sensib...

A whole-tree chamber (WTC) system was installed at Flakaliden in northern Sweden to examine the long-term physiological responses of field-grown 40-year-old Norway spruce trees [Picea abies (L.) Karst.] to climate change. The WTCs were designed as large cuvettes to allow the net tree-level CO(2) and water fluxes to be measured on a continuous basis. A total of 12 WTCs were used to impose combin...

Although otolith Strontium (Sr)/calcium (Ca) ratios have been widely used to reconstruct the past salinity environmental history of anguillid eels, factors affecting the Sr/Ca ratios in otoliths are incompletely understood. Japanese Eel (Anguilla japonica) elvers (mean length 54.7±2.1 mm) were collected in the estuary during their upstream migration and reared at 5 different salinities (0, 5, 1...

We study ion pair dissociation in water at ambient conditions using a combination of classical and ab initio approaches. The goal this is to disentangle the sources discrepancy observed computed potentials mean force. In particular, we aim understand why some models favor stability solvent-separated pairs vs contact pairs. found that differences can be explained by non-converged simulation para...
