Water Content and Insect Metabolism [PDF]

open access: bronzeNature, 1958
IT is well known that substantial changes in water content may occur in some insects. The haemolymph, for example, which may be copious and watery in a recently fed individual, may become scanty and treacly in a starved and desiccated specimen1. Reversible desiccation may slow down metabolism; it may be important in promoting survival in species ...

Changes in the Chloride Content of Ground Water in Pinellas County, Florida, Between 1947 and 1956 [PDF]

open access: bronze, 1958
In December 1956 the U. S. Geological Survey, in cooperation with the Florida Geological Survey and the Board of County Commissioners of Pinellas County, collected waterlevel and chloride content of water in 94 wells in Pinellas County. First sampled

Intelligent Monitoring System for Biogas Detection Based on the Internet of Things: Mohammedia, Morocco City Landfill Case

open access: yesBig Data Mining and Analytics, 2021
Mechanization is a depollution activity, because it provides an energetic and ecological response to the problem of organic waste treatment. Through burning, biogas from mechanization reduces gas pollution from fermentation by a factor of 20.

On the Nature of Freezing/Melting Water in Ionic Polysulfones [PDF]

open access: yesMacromolecules 54, 6477-6488 (2021), 2021
We investigate the behavior of hydrated sulfonated polysulfones over a range of ion contents through differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), and molecular dynamics (MD) simulations. Experimental evidence shows that at comparable ion contents, the spacing between the ionic groups along the polymer ...

A Mobile NMR Sensor and Relaxometric Method to Non-destructively Monitor Water and Dry Matter Content in Plants

open access: yesFrontiers in Plant Science, 2021
Water content (WC) and dry matter content (DMC) are some of the most basic parameters to describe plant growth and yield, but are exceptionally difficult to measure non-invasively. Nuclear Magnetic Resonance (NMR) relaxometry may fill this methodological

Identification of water content in nanocavities [PDF]

open access: yesNanoscale Research Letters, 2013
Abstract A tapered dielectric waveguide that scans, at constant height, a sample containing a viral capsid is studied by combining a lattice gas model to simulate water meniscus formation and a finite difference time domain algorithm for light propagation through the media involved.
