1. Interspecific variation in the allelopathic potential of the family Myrtaceae
Allelopathy is a type of biotic interference wherein a plant releases bioactive metabolites into an environment, thereby affecting the adjacent biota. Stressful environments stimulate the production of these metabolites. The present study tests the novel weapons hypothesis, which postulates that species belonging to the same genus and from the same environme

2. Isothermal seed germination of Adenanthera pavonina
This work reports aspects of seed germination at different temperatures of Adenanthera pavonina L., a woody Southeast Asian Leguminosae. Germination was studied by measuring the final percentages, the rate, the rate variance and the synchronisation of the individual seeds calculated by the minimal informational entropy of frequencies distribution of seed ger

3. The concept of informacional entropy can predict sequence learning, in rats? / O conceito de entropia informacional permite prever a aprendizagem serial, em ratos?
Prediction of environmental events, relying on memories of past regularities, is one of the fundamental functions of complex nervous systems. Sequences of serially ordered stimuli allow extracting information that defines its serial pattern. These patterns allow prediction of the next item in a sequence of events, facultating previous preparation to deal wit

4. Medida da qualidade de imagens de câmeras digitais usando entropia informacional. / Quality measurement of digital camera image using informational entropy.
This is an experimental work which uses the concept of informational entropy for digital image analysis. The researched literature shows that the informational entropy concept is used for image analysis, but the photographic equipment available in the market is not discussed. The aim of this work is to offer ,for photographers mainly, an experimental functio

5. Considerations on nonequilibrium entropy and temperature
Several aspects of the Thermodynamics of systems away from equilibrium are considered. Particular attention is given to the question of the concepts of entropy and temperature in arbitrary nonequilibrium conditions. Even though such state function and thermodynamic variable are elusive in such conditions, it is elaborated and discussed an approach to them th

6. Determinação entrópica do preço racional da opção européia simples ordinária sobre ação e bond: uma aplicação da teoria da informação em finanças em condição de incerteza / Entropic approach to rational pricing of the simple ordinary option of european-type over stock and bond: an application of information theory in finance under uncertainty
This thesis integrates Finance and Information Theory in order to create an alternative environment to the calculation of the rational price of the simple ordinary European option over stocks and bonds. One of the features of this new environment is to allow us to continue using the Newtonian calculus instead of the stochastic one. It creates a precise and c
