The tenets and principles of Gandhi are relevant in present times too. These include: Satya (Truth); Ahimsa(Non-violence); Vegetarianism; Mauna (Silence); Nai Talim (Basic Education). His entire political strategy, satyagraha, ahimsa and fasting was based on the superiority of 'soul force' to physical force. Today, on the one side when we are advancing with technology, its’ responsible use can help in addressing many problems of the society like corruption, lack of transparency, etc. The paper explores how Gandhian principles can be realized by adopting technology-driven interventions. The paper focuses mainly on issue of corruption and transparency and links how technology, can contribute to address the problem and realize ‘truth’ through transparency. The paper is based on review of secondary data

Content available remote Propagation and reflection of plane waves in a rotating magneto-elastic fibre-reinforced semi space with surface stress

The present paper investigates the propagation of quasi longitudinal (qLD) and quasi transverse (qTD) waves in a magneto elastic fibre-reinforced rotating semi-infinite medium. Reflections of waves from the flat boundary with surface stress have been studied in details. The governing equations have been used to obtain the polynomial characteristic equation from which qLD and qTD wave velocities are found. It is observed that both the wave velocities depend upon the incident angle. After imposing the appropriate boundary conditions including surface stress the resultant amplitude ratios for the total displacements have been obtained. Numerically simulated results have been depicted graphically by displaying two and three dimensional graphs to highlight the influence of magnetic field, rotation, surface stress and fibre-reinforcing nature of the material medium on the propagation and reflection of plane waves.
