A Unified Shell model for Buoyancy-Driven Turbulence
No full textWe construct a unified shell model for stably stratified and convective turbulence. Shell model simulation of stably stratified flow in turbulent regime exhibit Bolgiano-Obukhbov (BO) scaling in which the kinetic energy spectrum varies as . However, simulation of convective turbulence shows Kolmogorov's spectrum. These results are consistent with the direct numerical simulations of Kumar {\em et al.} [Phys. Rev. E {\bf 90}, 023016 (2014)]. We also observe a dual scaling ( and ) for a limited range of parameters in stably stratified flow
Sweeping has no effect on renormalized turbulent viscosity
No full textWe perform renormalization group analysis (RG) of the Navier-Stokes equation in the presence of constant mean velocity field , and show that the renormalized viscosity is unaffected by , thus negating the ``sweeping effect", proposed by Kraichnan [Phys. Fluids {\bf 7}, 1723 (1964)] using random Galilean invariance. Using direct numerical simulation, we show that the correlation functions for and differ from each other, but the renormalized viscosity for the two cases are the same. Our numerical results are consistent with the RG calculations
Energy transfers in small-scale and large-scale dynamos
No full textWe study energy transfers during magnetic energy growth in small-scale and large-scale dynamos. We perform direct numerical simulations for magnetic Prandtl number Pm =20 and 0.2 in a periodic box on 1024^3 grid. Energy fluxes and shell-to-shell energy transfers indicate that in small-scale dynamo for Pm =20, the magnetic energy growth takes place due to a non-local energy transfer from large-scale velocity field to small-scale magnetic field. On the other hand, in large-scale dynamo for Pm =0.2, local energy transfers from large-scale velocity field to large-scale magnetic field takes place
Excited-state intramolecular proton transfer of 2-acetylindan-1,3-dione studied by ultrafast absorption and fluorescence spectroscopy
No full textWe employ transient absorption from the deep-UV to the visible region and fluorescence upconversion to investigate the photoinduced excited-state intramolecular proton-transfer dynamics in a biologically relevant drug molecule, 2-acetylindan- 1,3-dione. The molecule is a ß-diketone which in the electronic ground state exists as exocyclic enol with an intramolecular H-bond. Upon electronic excitation at 300 nm, the first excited state of the exocyclic enol is initially populated, followed by ultrafast proton transfer (±160 fs) to form the vibrationally hot endocyclic enol. Subsequently, solvent-induced vibrational relaxation takes place (±10 ps) followed by decay (±390 ps) to the corresponding ground state. © 2015 Author(s)1561sciescopu
“Barley landraces: Ecological heritage for edaphic stress adaptations and sustainable production”
No full textSpontaneous mutation and natural selection pressure have contributed immensely to the genetic diversity of barley; a crop domesticated and grown since antiquity under diverse agro-ecological regions. Similarly, anthropogenic factors like cultural traditions and food preferences have also shaped the evolution of barley genetic diversity in the course of acclimatization under diverse ecosystems. Despite a rich genetic diversity, rapid depletion of barley genetic resources including the virtual extinction of several important landraces due to introduction of high yielding varieties and the loss of traditional farming systems remains a significant concern. Genetic gain in terms of higher grain yield and quality has obviously reduced the resilience of farmers’ varieties and landraces to environmental stresses; that could in fact be explored as an important source of genes and traits for improving barley adaptability to adverse agro-climatic conditions. Unfortunately, landraces are not being fully exploited in barley breeding programs mainly due to lack of inadequate information. In this backdrop, this article attempts to present an overview of the historical trends in barley conservation and the plausible use of barley landraces in modern breeding programs to achieve sustainable production suited to the current needs
Institutional Vacuum in Sardar-Sarovar Project: Framing ‘Rules-of-the-Game’
No full textFew large irrigation projects in India have been as elaborately planned as the Sardar- Sarovar Project (SSP), incorporating as it did the lessons of decades of irrigation project design and management. The project was to blaze a new trail in farmer-participatory irrigation project design and management with water user associations (WUAs) building their own distribution systems. However, as it unfolds, the institutional reality of the project is seen to be vastly different from its plans. If SSP is to chart a different course from scores of earlier large irrigationprojects, it must invent and put into place new rules of the irrigation management game.Length: pp.95-106Irrigation programsRiver basinsGroundwater irrigationSurface irrigationWater users associationsWater allocation
