Abstract In this paper, we theoretically study the electron Bernstein wave aided Hermite-Cosh-Gaussian laser beam absorption in collisional plasma with a static magnetic field. This may have potential to couple pre-existing coupled frequency <?CDATA ${\omega _1} = \omega + {\omega _0}$?> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msub> <mml:mi>ω</mml:mi> <mml:mn>1</mml:mn> </mml:msub> </mml:mrow> <mml:mo>=</mml:mo> <mml:mo>+</mml:mo>...

In this paper, a theoretical study has been proposed for excitation of electron Bernstein waves in collisional plasma with dc magnetic field by nonlinear interactions two cosh-Gaussian laser beams. The beat wave frequency and vector , exerts ponderomotive force on electrons. This the potential to drive field. convective loss is also discussed. An analytical formalism developed power going into respect total power. variation normalized distribution profile as function beam direction,...
Stimulated Raman forward scattering (SRFS) of an intense X-mode laser pump in a preformed parabolic plasma density profile is investigated. The excites wave and one/two electromagnetic sideband waves. In scattering, the growth rate parametric instability scales as two-third powers amplitude increases linearly with cyclotron frequency.
This paper discusses organic farming economics, focusing on its growth and challenges. Since the 1960s, when green revolution began, utilization of pesticides chemical fertilizers has Enhanced agricultural productivity, but this come at a significant environmental cost. Increasing consumer Awareness benefits for sustainability health have made it more in demand. However, changing to practices faces challenges, especially densely populated areas, where urgency food security is stronger. While...
A new method of observing two-photon optical transients is proposed, namely, by intensity switching incident cw laser beams. This method, which an alternative to the standard dc Stark or frequency-switching techniques, employs second-order (ac) effect throw active levels in out resonance appropriately intensities two Theoretical treatment for three basic nutation, free induction decay, and two-pulse echo thin samples using switching, given both cases: co- counter-propagating The feasibility...
The paper aims to investigate the phenomenon of monetising blogs as an example social media entrepreneurship. Blogging has emerged authoritative source viral marketing owing its potential creating extensive readership base. overwhelming popularity paves way for entrepreneurship allowing bloggers engage in various economic activities. study uses grounded theory methodology explore process monetisation a case by conducting interviews with who have successfully managed leverage their blogs....
