Microbe-Mediated Amelioration of Salinity Stress in Crops
Salinity is the key constraint that affects the crop growth, metabolism, and yield because of high abundance of salts present in the soil. The area and agriculture crop affected by salinity stress are increasi...

Formation of Coherent Structures and Impact on Turbulence Scaling in Solar-Wind Plasma
The governing dynamical equations of the right-handed circularly polarized dispersive Alfvén wave (DAW), which becomes dispersive owing to the finite frequency of the wave, and the slow Alfvén wave have been o...

Potential role of kinetic Alfvén waves and whistler waves in solar wind plasmas
Spacecraft observations indicate the signatures of highly oblique kinetic Alfvén waves (KAWs) and whistler waves in the solar wind plasma. In the present work, we explore the possible role of KAWs and whistler...
