The waxy monkey tree frog (Phyllomedusa sauvagii) and the Australian green tree frog (Litoria caerulea) benefit from two hygroscopically-enabled hydration processes; transcutaneous uptake of condensation on their skin [15] and reduced evaporative water loss [16] due to the condensed water film barrier covering their skin. Condensation volume is ...
Tree testing is a usability technique for evaluating the findability of topics in a website. [1] It is also known as reverse card sorting or card-based classification. [2] A large website is typically organized into a hierarchy (a "tree") of topics and subtopics. [3] [4] Tree testing provides a way to measure how well users can find items in ...
The biotic pump describes how water vapor given off by trees can drive winds and these winds can cross continents and deliver this moisture to far off forests. With this process and the fact that the foliage in forests have surface area, the forests can deliver more moisture to the atmosphere than evaporation from a body of water or equivalent ...
Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical.
Water vapor can also be indirect evidence supporting the presence of extraterrestrial liquid water in the case of some planetary mass objects. Water vapor, which reacts to temperature changes, is referred to as a 'feedback', because it amplifies the effect of forces that initially cause the warming. Therefore, it is a greenhouse gas. [2]
From the kinetic results, the rate of water uptake and water diffusion coefficients can be determined. The equilibrium mass values at the end of each humidity step were used to calculate the sorption and desorption isotherms (Figure 1b). The difference in water vapor uptake between the sorption and desorption isotherms is called the hysteresis ...
Less volatile than water (vapor pressure lower than water), with easily reversible desorption into water and steam in the boiler; Good solubility in water at low to moderate temperatures; Non-reactivity with other salts in the cycle and chemically stable over the range of temperatures and pressures in the hygroscopic cycle; Are non-toxic and ...
The electrolytic sensor uses two closely spaced, parallel windings coated with a thin film of phosphorus pentoxide (P 2 O 5). As this coating absorbs incoming water vapor, an electrical potential is applied to the windings that electrolyze the water to hydrogen and oxygen. The current consumed by the electrolysis determines the mass of water ...
