Periodic Electro-Optical Characteristics of PDLC Film Driven by a Low-Frequency Square Wave Voltage
Crystals, 2022 The electro-optical features of the PDLC films applied with a low-frequency square wave voltage were investigated. The transmittance curves indicated the double frequency of the applied voltage at 0–50 Hz, which resulted from the relaxation of an ...

Transhumanism Between Human Enhancement and Technological Innovation [PDF]
, 2016 Transhumanism introduces from its very beginning a paradigm shift about concepts like human nature, progress and human future. An overview of its ideology reveals a strong belief in the idea of human enhancement through technologically means.

Ion channels and ion selectivity [PDF]
Essays in Biochemistry, 2017 Specific macromolecular transport systems, ion channels and pumps, provide the pathways to facilitate and control the passage of ions across the lipid membrane. Ion channels provide energetically favourable passage for ions to diffuse rapidly and passively according to their electrochemical potential.

CeROArt : Conservation, Exposition, Restauration d'Objets d'Art, 2021 Ion exchange resin was first synthesized in 1930 and is still widely used, mainly for water purification. The compound has already been used in certain restoration operations; however, at present there is no literature dealing with the exchange processes

Note on Four Dp-Branes at Angles [PDF]
, 2000 In this note we analyse the dynamical potential of a system of four $Dp$-branes at arbitrary angles. The equilibrium configurations for various values of the relative angles and distances among branes are discussed.

Dynamic ion-ion and water-ion interactions in ion channels
Biophysical Journal, 1992 The dynamic interactions among ions and water molecules in ion channels are treated based on an assumption that ions at binding sites can be knocked off by both transient entering ions and local water molecules. The theory, when applied to a single-site model K+ channel, provides solutions for super- and subsaturations, flux-ratio exponent (n') greater

Nutrient homeostasis within the plant circadian network
Frontiers in Plant Science, 2015 Circadian clocks have evolved to enhance adaptive physiology in the predictable, fluctuating environment caused by the rotation of the planet. Nutrient acquisition is central to plant growth performance and the nutrient demands of a plant change ...
