Study of Surface Tension and Surface Properties of Non-Ideal Binary Liquid Mixtures [PDF]
In this research, surface tension and surface properties of binary mixtures of water with a series of aliphatic carboxylic acids (C1-C4)were investigated by different models at temperature range between (288.15 and 328.15) K.

Two dimensional time evolution of beam-plasma instability in the presence of binary collisions [PDF]
Energetic electrons produced during solar flares are known to be responsible for generating solar type III radio bursts. The radio emission is a byproduct of Langmuir wave generation via beam-plasma interaction and nonlinear wave-wave and wave-particle ...

The study of direct dye sorption on flax fibers during dyeing [PDF]
This article presents the study of direct dye sorption onto the flax fiber during the dyeing process in the presence of an inorganic electrolyte. The previously prepared linen fabric was subjected to dyeing by a standard process, varying in concentration

On Langmuir’s periodic orbit [PDF]
Niels Bohr successfully predicted in 1913 the energy levels for the hydrogen atom by applying certain quantization rules to classically obtained periodic orbits. Many physicists tried to apply similar methods to other atoms. In his well-known 1921 paper, I.~Langmuir established numerically the existence of a periodic orbit in the helium atom considered

Observations of narrow bipolar events reveal how lightning is initiated in thunderstorms
How lightning is initiated inside storms has been a long-standing and fundamental question. Here, the authors report observations of a previously unrecognized type of discharge, called fast positive breakdown, that is found to initiate many and ...

Fast negative breakdown in thunderstorms
Recent studies have shown that lightning is initiated by a newly-recognized discharge process called fast positive breakdown. Here, the authors present observational evidence of fast breakdown but of negative polarity, seemingly contrary to current ...
