Few studies have evaluated the efficiency of methods for sampling ants, especially in regions with highly variable vegetation physiognomies such as the Cerrado region of central Brazil. Here we compared three methods to collect ground-dwelling ants: pitfall traps, sardine baits, and the Winkler litter extractor. Our aim was to determine which method would be most appropriate to characterize the...

This article presents a study of the factors that influence mechanism soil-structure interaction with pilot building having concrete walls and their impact on performance. To illustrate studies carried out, numerical modeling four-floor wall was performed, subjected to vertical actions, supported by slab-on-ground foundation, using Finite Element Method (FEM), together specific 3D software for ...
The correspondence (1907-1930) between two leading European neurologists, Cornelis Winkler (1855-1941) and Constantin von Monakow (1853-1930), has been preserved in Amsterdam and Zurich. For this paper, letters exchanged during World War I were studied. Professional as well as personal issues were discussed. An international neurology meeting in Berne in September 1914 had to be cancelled due t...
Commercially available prosthetic hands are simple grippers with one or two degrees of freedom; these pinch type devices have two rigid fingers in opposition to a rigid thumb. This paper focuses on an innovative approach for the design of a myoelectric prosthetic hand. The new prosthesis features underactuated mechanisms in order to achieve a natural grasping behavior and a good distribution of...
