Gestation
In the introductory chapter of this book it is explained that in the lower vertebrates there are lymphatic vessels but no lymph nodes; the lymphoid tissue in fish and amphibia is associated with myeloid tissue in such organs as the intestines, kidney, and liver. Lymph nodes first appear in certain birds, but it is only in mammals that they are invariably present. However, even in mammals, where...

term "large granules." It is of some interest that these granules behave in many ways like the granules of the adrenal medulla which contain the pressor amines. By differential centrifugation it has been shown that the granules with the greatest density contain the largest amount of histamine, and also, that the intravenous injection of a preparation of these granules has less vasodepressor act...
متن کاملNeighbourly Irregular Derived Graphs
A connected graph G is said to be neighbourly irregular graph if no two adjacent vertices of G have same degree. In this paper we obtain neighbourly irregular derived graphs such as semitotal-point graph, k^{tℎ} semitotal-point graph, semitotal-line graph, paraline graph, quasi-total graph and quasivertex-total graph and also neighbourly irregular of some graph products.
متن کاملGestation
Of the seven chapters, the three written by the editor are the most original and challenging. "Protein Biology" describes some of the characteristics of enzymes as proteins, discusses the role of enzymes in the structure and function of living matter, and touches on biological relativity. The final two chapters by Martin are a rather delightful if eclectic mixture of technical examples and phil...
متن کاملSolving Irregular Problems through Parallel Irregular Trees
This paper presents PIT, a library for the parallelization of irregular problems on distributed memory architectures. All the strategies underlying the definition of the library can be expressed in terms of operations on a PITree, a parallel version of the tree data structure oriented to irregular problems. We consider the application of PIT to two well known irregular problems: adaptive multig...
