The spouted and fluidized bed technologies are usually employed in operations of drying, coating and granulation of particles by the chemical and pharmaceutical industries. The use of these techniques in agronomy is limited to the treatment of some species of seeds. In this work, the objective was to analyse the fluid-dynamics of fluidized and spouted beds when broccoli (Brassica oleracea L. var. Italica) seeds are used and also to verify the influence on seed germination after 60 min of seed exposition to spouting or fluidization, at room temperature. The fluid-dynamics was defined by the measurements of the bed pressure drop as a function of the air flow rate for different seeds loads. The experimental conditions were based on the physical properties of the seeds and were limited by the apparatus dimensions. The cone-cylindrical bed was constructed in plexyglass to permit flow visualization. The values of the parameters: maximum pressure drop, minimum spouting flow rate and pressure drop, and stable spout pressure drop were experimentally obtained from the fluid-dynamic analysis and were compared with the values calculated by empirical equations found in the literature. The same procedure was carried out with the fluidized bed and the important parameters for this regime were the air velocity and the bed pressure drop at minimum fluidization. The analysis of seed germination indicated that no damage was caused to the seeds by the spout or fluidization processes.

This article reports the results from the research work which objects the critical and profound study about the ADHD (Attention Deficit/Hyperactivity Disorder) in the courses for teachers' development in College Education, under its various dimensions - social, cultural, pedagogical, biological. The investigation focused on five adults with diagnosis for ADHD. The methodology used was the Case Study, developed from the Oral History as a source of data. The results that were obtained suggest that the study, proposed in the research, may contribute significantly for the teachers to know determining factors of the school performance of students with this disorder, as well as to guide them in the search of partnership with other professionals - doctors and psychologists, for example - when such partnership becomes necessary.
