Chilling Out Warming Up How Animals Survive Temperature
It doesn t matter what the outside temperature is—they must maintain the same internal temperature. For us the commonly accepted average body temperature is 98.6 °F (even though it may vary among individuals). Most other mammals range from 97 °F to 103 °F birds have an average body temperature

Collision Integrals for Interactions Involving Atoms in
Transport collision integrals for low-lying excited states of nitrogen atoms and ions are derived in the framework of a phenomenological approach following where possible also the traditional multipotential procedure. The two sets of results are compared considering critically the observed deviations and finally the proposed model is validated by comparison with oxygen atom−atom
