Açaí is a source of wealth for riverine families and has been promoting the development of the Amazon River estuary. After depulping the fruits to produce the wine, the seeds of açaí are deposited near the houses without proper destination. This problem can become a solution, generating green energy in isolated communities. The aim of this study is estimate the energetic potential of açaí seeds. This work was done in Ilha das Cinzas, Gurupá-PA, Eastern Amazon. The samples were collected with 10 families (n = 40), packed and sent to a forced ventilation oven 105 ± 2ºC. It was done an immediate analysis, in duplicate, in accordance with ASTM D1762-84. The highest heating value (HHV) was determined with volatile material values, fixed carbon and ash content. In addition, the thermogravimetric analysis and differential scanning calorimetry were performed on the PerkinElmer TG-DSC equipment, model DSC-7. The mean values of volatile materials (74.57%), ash content (1.70%) and fixed carbon (23.74%) were similar to those found in the oil seed literature. HHV ranged from 19.91 MJ kg-1 to 20.10 MJ kg-1, indicating that the waste of açaí seeds is an excellent resource to be transformed into a biogas. The mean pulp content was 21% and the açaí seeds was 79%, with a moisture content of 30%. At 200oC, the mass loss increases rapidly, reaching maximum rate of 5% min-1 near 300oC. At a temperature of 500°C, all the organic mass was degraded, passing through the combustion and gasification process, leaving only a small amount of ash. At the beginning of the heating, until the temperature near 100ºC, energy consumption occurs. Thereafter, the release process begins, increasing with increasing temperature, with a small peak near 320oC and maximum enthalpy close to 500oC. The variation of the açaí seed enthalpy, enables it to the energetic use, whose optimization depends on equipment that can keep temperatures above 300ºC. Seasonality production influences the yield of açaí seed considerably. In the off-season production, the pulp proportion decreases and the seed proportion increases. These experimental results confirm the qualitative potential of açaí seeds as a source of bioenergy, and the possibility of its use to help solve the problem of isolated Amazonian communities that still live without regular energy supply.

The cotton boll weevil is an insect that has its life cycle very close with the cotton culture. Its preferences for the strutures of frutifications (squares and bolls), used as feed and reproducing sites, imposes a great number of damages on culture. In this sense, founded at certain levels of population, this insect becomes a serious cotton pest, needing immediactive intervention for culture productivity security. Following the orientations of the Integrated Pest Management Program, it's possible to determine when the insect population reaches hazards levels to the culture and to decrease the number of pesticides applications needs to the pest control. In the Brazilian environment there are a great number of promising natural enemies to be used as biological control agents. But it is very difficult to determine the number of these populations and when to liberate them on the crop, able to secure an efficient pest control. The main objective of this work was to develop a simulation system in order to monitor the populational dynamics of the cotton boll weevil (Anthonomus grandis Boheman, Coleoptera: Curculionidae) at different levels of infestation, interacting the numeric simulation and artificial intelligence techniques. The source program was developed in C language, in a SUN Sparc Station UNIX-OS, sponsored by DOD-EMBRAPA's PhD-Programme, in DENSIS-FEE/UNICAMP (PESSOA, 1994). The program has molecular structure, allowing the inclusion of new modules, as well as modifications in the existing modules to incorporate particular situations of regions that will be studied, without compressing the program structure.
