2. Estudo comparativo entre métodos de calibração de aplicadores clínicos de radiação beta / COMPARATIVE STUDY AMONG CALIBRATION METHODS OF CLINICAL APPLICATORS OF BETA RADIATION
90Sr+90Y clinical applicators are instruments used in brachytherapy procedures and they have to be periodically calibrated, according to international standards and recommendations. In this work, four calibration methods of dermatological and ophthalmic applicators were studied, comparing the results with those given by the calibration certificates of the ma

3. Restrições da correlação nos testes de germinação de sementes e emergência de plântulas / Restrictions of the correlation in the tests of seed germination and seedling emergence
Coefficient of Pearson r is used to compare scientific tests. In seeds technology it is used to compare results of procedures that measure vigour. When the correspondly similar results are not found in very similar conditions, Persons correlation faces criticism mainly due to two factors. The first one comes from statistics for whose usage of Persons correla

5. Effects of bovine semen cryopreservation on sperm plasmatic, acrosomal, and mitochondrial membranes and chromatin structure using fluorescent probes / Efeitos da criopreservação do sêmen bovino sobre as membranas plasmática, acrossomal e mitocondrial e estrutura da cromatina dos espermatozóides utilizando sondas fluorescentes
The process of cryopreservation causes damages in the sperm cellular function which may lead to a reduction in fertility. New techniques to evaluate sperm viability may improve the process of semen evaluation. The present work was divided in two experiments. Experiment 1 aimed the development and validation of practical techniques with high repetibility for

6. Stability of vitamins and and in foods enriched with different sources of iron. / Estabilidade das vitaminas A e E em alimentos enriquecidos com diferentes fontes de ferro.
The food enrichment with vitamins and minerals is a very common practice nowadays, allowing to improve the nutritional value of the food and to replace nutrients lost during the processing and or stocking. However, the added nutrients can suffer negative interaction during rack life of the food, as it happens with iron (pro-oxidant) and vitamins A and E (ant
