In this paper, we propose Viola, which can define CMG grammar graphically and execute a visual system on the same screen. By using Viola, the user can define various visual systems interactively. It became possible to define grammars using graphical expressions and construct visual systems dynamically, while checking the grammar at the execution time. We have actually implemented Viola in Java ...

BACKGROUND The genus Gavialis comprises a single living but endangered species, G. gangeticus, as well as fossil species recorded in the Miocene to Pleistocene deposits of the Indian subcontinent. The genus is also represented in the Pleistocene deposits of Java by the species G. bengawanicus, which was recently recognized to be valid. Surprisingly, no detailed report of the genus exists betwee...

In vitro evaluation of sun protection activity of some medicinal herbs by SPF determination, to find out which herbal extracts have the best protection activity and can be used as sunscreen agent. Sun rays are the most environmental harmful factor which affect skin, cause sun burn and photo aging. According to the previous studies the plant’s flavonoids are suitable absorbents for UV rays. In t...

To obtain high yields of winter wheat, it is important to control the contamination crops with weeds. It known that yield losses can be 30% or more due presence segetal vegetation in wheat crops. With intensive technology growing chemical method protection against weeds an extremely element. The paper highlights data on species composition and class agrocenosis. effectiveness herbicides their t...

Between October 2001 and March 2002, 103 specimens of A. tricolor from Angra dos Reis (23 degrees 01' S, 44 degrees 19' W), in the coastal zone of the State of Rio de Janeiro, Brazil, were analyzed in order to study their metazoan parasite infracommunities. Ten species of metazoan parasites were collected: 4 digeneans, 1 cestode, 1 acantocephalan, 2 nematodes, 1 copepod, and 1 hirudinean; 77.7%...

The dietary niche and morphological adaptations of a species should be highly correlated. However, conflicting selective pressures may make predictions about diet difficult without additional knowledge of a species’ life history. We tested the reliability of predicting a bat’s diet from its wing morphology using data for Spix’s diskwinged bat (Thyroptera tricolor). The species had been predicte...

Management of the few regulated ornamental fisheries relies on inadequate information about the life history of the target species. Herein, we investigated the reproductive biology of the most heavily traded marine invertebrate in the western Atlantic; the blue-legged hermit crab Clibanarius tricolor. We report on density, individual-level, and population-level reproductive parameters in 14 pop...
