Cavitating Langmuir Turbulence in the Terrestrial Aurora [PDF]
, 2012 Langmuir cavitons have been artificially produced in the earth's ionosphere, but evidence of naturally-occurring cavitation has been elusive. By measuring and modeling the spectra of electrostatic plasma modes, we show that natural cavitating, or strong,

Generalization of the Langmuir–Blodgett laws for a nonzero potential gradient [PDF]
, 2015 The Langmuir–Blodgett laws for cylindrical and spherical diodes and the Child–Langmuir law for planar diodes repose on the assumption that the electric field at the emission surface is zero.

Removal of Copper (II) Ions from Polluted Water Using Modified Wheat Bran
Environmental and Climate Technologies, 2021 The discharge of wastewater containing heavy metals into waterbodies is a major environmental issue that can influence the quality of the water supply; therefore, it is important to remove the pollutants dangerous to living organisms.

Two dimensional time evolution of beam-plasma instability in the presence of binary collisions [PDF]
, 2016 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 ...

Observations of narrow bipolar events reveal how lightning is initiated in thunderstorms
Nature Communications, 2016 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 ...

Phosphorus behavior under long-term fertilization in the intensive rice cultivation system
Plant, Soil and Environment, 2023 Advocating proper phosphorus (P) fertilisation is necessary to save this limited natural resource and to save the investment in rice cultivation. This study aimed to evaluate changes in phosphorus availability, total phosphorus in soil, phosphorus ...

Stopping Frequency of Type III Solar Radio Bursts in Expanding Magnetic Flux Tubes [PDF]
, 2015 Understanding the properties of type III radio bursts in the solar corona and interplanetary space is one of the best ways to remotely deduce the characteristics of solar accelerated electron beams and the solar wind plasma.

Zakharov simulation study of spectral features of on-demand Langmuir turbulence in an inhomogeneous plasma [PDF]
, 2007 We have performed a simulation study of Langmuir turbulence in the Earth's ionosphere by means of a Zakharov model with parameters relevant for the F layer.
