    The PRISM (Pliocene palaeoclimate) reconstruction: time for a paradigm shift

    Oct 28, 2013 - Global palaeoclimate reconstructions have been invaluable to our understanding of the causes and effects of climate change, but single-temperature representations of the oceanic mixed layer for data–model comparisons are outdated, and the time for

    Endophytic establishment of Azorhizobium caulinodans in wheat

    Mar 22, 1997 - Nitrogen fixing nodules are formed on the roots and stems of the tropical legume Sesbania rostrata by Azorhizobium caulinodans as a result of crack entry invasion of emerging lateral roots. Advantage was taken of this invasion capability of A.

    A constant shear stress core flow model of the bidirectional vortex

    Dec 4, 2008 - In this paper, we discuss the merits of two models for the swirl velocity in the core of a confined bidirectional vortex. The first is piecewise, Rankine-like, based on a combined-vortex representation. It stems from the notion that a uniform shear

    Costs of immune response in cold-stressed laboratory mice selected for high and low basal metabolism rates

    Oct 7, 2003 - To study whether mounting an immune response is energetically costly, mice from two lines divergently selected for high (H-BMR) and low (L-BMR) basal metabolic rate (BMR) were immunized with sheep red blood cells. Their energy budgets were then
