#' Effects of temperature on decomposition rates according to the DAYCENT model

#' 
#' @param Temp A scalar or vector containing values of soil temperature for
#' which the effects on decomposition rates are calculated
#' @return A scalar or a vector containing the effects of temperature on
#' decomposition rates (unitless).
