17. Survival of Ucides cordatus (Decapoda: Ocypodidae) megalopae during transport under different conditions of density and duration
Target areas for Ucides cordatus (Linnaeus, 1763) restocking programs are often located far from the laboratory where larval rearing is developed. During translocation, the larvae are submitted to highly stressful conditions due to handling, packing, and transport activities. The aim of the present study was to assess the mortality rates of U. cordatus megal

19. Evaluation of CTMP pulp´s behavior towards hydrogen peroxide bleaching: utilization of sub/supercritical carbon dioxide / Avaliação do comportamento de polpa CTMP frente ao branqueamento com peróxido de hidrogênio: utilização de dióxido de carbono no estado sub/supercrítico
The bleaching of chemithermomechanical pulp (CTMP) is usually performed using hydrogen peroxide (H2O2) in alkaline medium. This stage produces high quantity of effluent to be treated, increasing the costs of the industrial process. The usage of liquid carbon dioxide (CO2) under sub/supercritical conditions can help in reducing the amount of liquid effluents

20. Dry material losses and qualitative evaluation of corn grain stored in hermetic units / Determinação da perda de matéria seca e avaliação qualitativa de grãos de milho armazenados em bolsas herméticas
A significant increase in the grain sector has been observed over the last few years, leading to the expansion of the balance of trade. However, in various Brazilian States, storage systems are composed of old structures, precarious for storage which end up compromising the quality of the product during storage. In order for the sector to increase exports an

21. Talauma ovata St. Hil. seed conservation / Conservação de sementes de Talauma ovata St. Hil.
The research aimed to study the influence of the seed moisture content and storage temperature on Talauma ovata seed conservation. Thus, two seed lots with initial moisture content of 23.5% (lot 1) and 23.8% (lot 2) were dried and obtained tree moisture content levels in each lot, and the moisture contents were 17.4 %, 10.9% and 7.1% for lot 1 and 15.8%, 13.
