Jean Watson had planned to write a book about an integrated curriculum for a baccalaureate curriculum in nursing. Instead, she developed a novel structure for basic nursing processes, which was published in the bookNursing: ThePhilosophy and Science of Caring (Watson, 1979). The work presented in that book solved some of Watson’s conceptual and empirical problems about nursing and formed the fo...

We begin with a review of the basic molecules responsible for the functioning of all organisms’ cells. Much of the material here comes from the introductory textbooks by Drlica [4], Lewin [7], and Watson et al. [10]. Good short primers have been written by Hunter [6] and Brāzma et al. [2]. What sorts of molecules perform the required functions of the cells of organisms? Cells have a basic tensi...

We give a necessary and sufficient condition for the convergence in distribution of a conditioned Galton-Watson tree to Kesten’s tree. This yields elementary proofs of Kesten’s result as well as other known results on local limit of conditioned Galton-Watson trees. We then apply this condition to get new results, in the critical and sub-critical cases, on the limit in distribution of a Galton-W...
