combinations." Portrait painting can depict the subject "full-length" (the whole body), "half-length" (from head to waist or hips), "head and shoulders" (bust)
Watercolor Watercolor painting allows artists to use many techniques, including wet-on-wet painting, in which the paint moves freely on wet paper. Another

binder. It has been the most common technique for artistic painting on canvas, wood panel, or copper for several centuries. The advantages of oil for
The Beauty (Russian: Красавица, romanized: Krasavitsa) is an oil-on-canvas painting executed in 1915 by the Russian artist Boris Kustodiev. The painting
Wet-on-wet, or alla prima (Italian, meaning at first attempt), direct painting or au premier coup, is a painting technique in which layers of wet paint
Shams Charania: The NBA will return to painting the Larry O'Brien trophy at center court and Finals script logo on the home team's floor for the Finals starting this season, per sources. The last ti...
Aqueous cations permeate subnanoscale pores by crossing free energy barriers dominated by competing enthalpic contributions from transiently decreased ion-solvent and increased ion-pore electrostatic interactions. This commonly accepted view is roote...
Proteins change their charge state through protonation and redox reactions as well as through binding charged ligands. The free energy of these reactions are dominated by solvation and electrostatic energies and modulated by protein conformational re...
In this work, we analyzed an isotropic colloidal model incorporating both short-range sticky attractions and long-range electrostatic repulsions. We computed the zero-shear viscosity and second virial coefficient for a dilute colloidal suspension (i....
We have studied the electrostatic screening effect of NaCl solutions on the interactions between anionic lipid bilayers in the fluid lamellar phase using a Poisson-Boltzmann based mean-field approach with constant charge and constant potential limiti...
We consider an electrostatic attractive-repulsive differential system in the nonnegative quadrant. Under some condition on the constants there exists a unique global solution. The main difficulty is to prove uniqueness when starting at the corner of...
We consider general aspects of the physics underlying the flight of Gossamer spiders, also known as ballooning spiders. We show that existing observations and the physics of spider silk in the presence of the Earth's static atmospheric electric field...
Seagate SeaShield was a physical electrostatic protection shield feature of Seagate Medalist series hard drives, and followed by the Barracuda series
A recently developed lattice field theory approach to the statistical mechanics of charged polymers in electrolyte solutions [S. Tsonchev, R. D. Coalson, and A. Duncan, Phys. Rev. E {\bf{60}}, 4257, (1999)] is generalized to the case where ground-s...
We study the steady-state expansion of a collisionless, electrostatic, quasi-neutral plasma plume into vacuum, with a fluid model. We analyze approximate semi-analytical solutions, that can be used in lieu of much more expensive numerical solutions....
This note revolves on the free Dirac operator in $\mathbb{R}^3$ and its $δ$-shell interaction with electrostatic potentials supported on a sphere. On one hand, we characterize the eigenstates of those couplings by finding sharp constants and minimiz...
The electrostatic problem of two coaxial parallel charged disks of different radii in infinite space is solved by expansion in terms of complex potentials. For perfectly conducting disks a pair of coupled integral equations is derived for the two wei...
The ultrasensitive electroscope is a precision instrument designed to detect extremely small amounts of electric charge and weak electrostatic fields that are undetectable by conventional electroscopes. It operates by converting minute electrical charges into…
COSY INFINITY uses a beamline coordinate system with a Frenet-Serret frame relative to the reference particle, and calculates differential algebra-valued transfer maps by integrating the ODEs of motion in the respective vector space over a differenti...
