NEW APPROACH ABOUT NEOTROPICAL HELMINTHOLOGY

A history of human helminthology

If divines and physicians could not agree, what was the state supposed to do? Evn if a consensus had emerged, was there any administrative body with sufficient authority, efficiency and resources to enforce the necessary measures against an uncertain and unwilling populace? Slack drily tells us that "The postponement of the Lord Mayor's Show and the celebration of James I's coronation in 1603 m...

A New Approach about Lü System

About new hybrid approach in cancer modeling

In the present article we demonstrate a new hybrid model of tumor growth. Our model is stochastic by tumor population development and strongly deterministic in cell motility dynamics and spatial propagation. In addition, it has excellent extendibility property. Described model is tested on general behavior and on avascular tumor growth case qualitatively.

New combinations in Neotropical Thelypteridaceae

288 new combinations of Neotropical Thelypteridaceae taxa are proposed in order to recognize monophyletic genera, based on the results of the most recent molecular phylogeny of the family, as well as the morphological uniformity of characters for each genus. The new nomenclatural combinations correspond to 186 Amauropelta taxa, 77 species of Goniopteris, and 25 Steiropteris taxa. A key to all n...
