18. DeterminaÃÃo de perdas de frutos nos mecanismos recolhedor e transportador de colhedoras de cafà / Determination of fruit losses at the collector and at the conveyor of the coffee harvesters
The use of the agricultural mechanization is one of the greatest farmers` tools to manage cultures efficiently and to reduce costs. The mechanized harvest is extremely dynamic because every moment new decisions need to be done and modifications in the process need to be accomplished. Therefore, one question to be evaluated is the self-propelling harvester fr

19. Avaliação da atividade antioxidante, mutagênica e antimutagênica de polpas de frutas
Several studies have pointed out that consumption of fruits is related to the reduced risk of diseases, such as coronary heart and neurodegenerative diseases, as well as certain types of cancer. Although several fruits in natura and compounds isolated from them have been already studied, there exist little data on frozen fruits composition and their biologic

20. Polyphenolic Constituents and antioxidant properties of the Juçara Palmtree (Euterpe edulis) fruit pulp / Constituintes polifenolicos e propriedades antioxidantes da polpa do fruto da palmeira Juçara (Euterpe edulis)
Introduction. A large number of studies have pointed out the importance for human health of an enormous variety of phytochemicals occurring in foods because of their role as antioxidants and metabolic signalers. The fruit of the palmtree jussara (Euterpe edulis Mart.) shares both compositional and sensory properties with assai (Euterpe oleraceae Mart.), and

24. Euterpe Olerácea (Açaí) as an Alternative Oral Contrast Agent in MR Imaging (MRI) of the Gastrointestinal (GI) System: Characterization and Clinical Preliminary Results / Caracterização e aplicação preliminares de um agente de contraste oral natural para imagens por ressonância magnética do trato gastrintestinal
The use of contrast agents is a common practice in medical imaging protocols. Paramagnetic properties of certain compounds present in contrast agents can affect Magnetic Resonance Imaging (MRI) signals. For abdominal applications, they are usually injected, but may also be administered orally. However, their use as a routine technique is limited, mainly due
