This paper presents the boundary-type schemes of the first-and the second-order sensitivity analyses by Trefftz method. In the Trefftz method, physical quantities are approximated by the superposition of the T-complete functions satisfying the governing equations. Since the T-complete functions are regular, the approximate expressions of the quantities are(More)

If the delayed hypersensitivity reaction caused by costus root oil were to be used as a means of aggregating lymphoid cells, these cells(More)
