	EO Library: The Water Cycle
		The notion that water is continually circulating from the ocean to the atmosphere to the land and back again to the ocean has interested scholars through most of recorded history.
		Water is everywhere on Earth and is the only known substance that can naturally exist as a gas, liquid, and solid within the relatively small range of air temperatures and pressures found at the Earth's surface.
		In all, the Earth's water content is about 1.39 billion cubic kilometers (331 million cubic miles) and the vast bulk of it, about 96.5%, is in the global oceans.

	The effect of low water content on seed longevity - Hu, C., Zhang, Y., Tao, M., Hu, X. & Jiang, C.
		Because water content at a given relative humidity increases as temperature decreases, these authors proposed that the optimum water content for seed storage would increase as the storage temperature was lowered.
		This detrimental effect was apparent during the final drying stage in wheat, rice and millet when water contents were reduced from 3 to 2% (wheat, 96±1 to 93±1% germination and rice, 96±1 to 90±5% germination) or from 1.8 to 0.85% (millet, 92±3 to 51±3% germination).
		The decline in germination percentage was fastest for seeds stored with higher water contents (9.8% for wheat, 7 and 8.8% for rice, 9.4 and 5.8% for millet, 4.4% for peanut) and lower water contents (2.2 and 3% for wheat, 2 and 3% for rice, 0.85 and 1.8% for millet, 1% for peanut).

	The effects of water content during storage on physiological activity of cucumber seeds - Zeng, X.Y., Chen, R.Z., Fu, ...
		Water content and temperature are the main factors influencing seed longevity during storage.
		Conductivity of the soak water was assayed in 2 or 4 h intervals for the first 12 h of imbibition, and the rate of electrolyte leakage was calculated from the linear regression of the conductivity versus time relationship.
		Associated with the decline in germination at all water contents was a decrease in the growth of the embryonic axis (Abdul-Baki and Anderson, 1973) (Tables 1 and 2), an increase in the leakiness of membranes (Simon and Raja Harun, 1972) (Tables 1 and 2) and a decline in the activity of antioxidant enzymes (Table 2).

	Narrow Mental Content
		Similarly, a narrow content of a belief or other mental state is a content that could not be different unless the subject who has the state were different in some intrinsic respect: no matter how different the individual's environment were, the belief would have the same content it actually does.
		What determines the broad content of their thoughts is not merely the environment they are in at the moment, but also the environment in which they first acquired their thoughts and beliefs about watery stuff.
		We can easily find a content of the subject's perception that is a content of the very same perceptual state but which characterizes it more narrowly: the subject sees the facing surface of the apple, and it is by virtue of seeing the facing surface that she sees the apple as a whole.

	On the identification of macroscopic root water uptake parameters from soil water content observations
		For this study, the macroscopic root water uptake is considered to be linearly decreasing with depth with A and B parameters conditioning, respectively, the maximum root water uptake at the surface and the decreasing rate with depth.
		Results show, for soils with different textures, that the soil water content and, to a lesser extent, the time derivative of soil water content are quite insensitive to root water uptake parameters, at least compared to soil hydraulic parameters.
		Therefore a robust identification of root water uptake parameters by means of a full SVAT inversion is unlikely to be achieved during a dry period with soil water content observations at least when some other parameters driving the system, like soil hydraulic properties, are not error free.

	Water content in Our Body
		Water content in the body influences the functions of the various proteins and enzymes that are dissolved in it.

		However, water from natural sources may contain minerals that can be beneficial to the body in specific conditions due to their reaction and affinity towards the mineral content in the food.

	What is unfreezable water? Is it the same as bound water or water of hydration?
		Water that doesn't freeze under certain conditions is sometimes called 'unfreezable water' by various workers in the fields of cryobiology, anhydrobiology, food science and elsewhere.
		The freezing point of water may be lowered by the osmotic effects of dissolved solutes or by the hydration effects of macromolecules or biological ultrastructures such as membranes.

		Therefore, the water content of materials containing extraneous matter (such as cement etc.) may require special treatment or a qualified definition of water content.
		This is especially important if the water content will be used to calculate other relationships such as moist mass to dry mass or vice versa, wet unit weight to dry unit weight or vice versa, and total density to dry density or vice versa.
		This occurs since 1 plus the water content (not in percent) will have four significant digits regardless of what the value of the water content is; that is, 1 plus 0.1/100 = 1.001, a value with four significant digits.

	ARS \| Publication request: Dielectrics - Beyond Water Content
		Technical Abstract: To properly understand dielectric methods for determining soil water content, it is necessary to study the frequency relation of the complex dielectric properties, known as dielectric spectroscopy.
		The frequency analysis of the real and imaginary dielectric components were used to calculate the square root of the apparent dielectric number, ADN, which is the measured value from TDR and impedance dielectric systems.
		The ADN back-calculated for bound water increased 59% at a frequency of 0.1 GHz compared with that for the square root of the real dielectric at 1 GHz frequency.

	The effect of water content
		Note that part of the reason for the low water vapour content of the atmosphere above Antarctica is that, at these low temperatures, the saturation vapour pressure of water is low.
		When the relative humidity profile of the original model was doubled, it actually exceeded 100% at one level, and had to be reset to 100%.
		It seems, therefore, that at a very dry site such as the Antarctic plateau, the exact value of the water content is not an important factor in determining the observing conditions in the dark regions of the near- and mid-IR spectrum.
