We present a new mechanism for inflation which exhibits speed limit on scalar motion, generating accelerated expansion even steep potential. This arises from explicitly integrating out the short modes of additional fields coupled to inflaton $\phi$ via dimension six operator, yielding an expression effective action includes nontrivial (logarithmic) function $(\partial\phi)^2$. The appears at br...

the effects of plant densities (25, 35 and 45 plants m-2 as d1, d2 and d3 respectively), and inoculation with rhizobium bacteria (without rhizobium, with rhizobium and rhizobium + microelement application), on growth and yield were studied in chickpea (cicer arietinum l.). experiment was carried out in 2008 at research farm of the faculty of agriculture of university of mohaghegh ardabil, a fac...
