27. Study of the process of osmótica dehydration and drying of filés of it will mapará (Hypophthalmus edentatus). / Estudo do processo de desidratação osmotica e secagem de files de mapara (Hypophthalmus edentatus).
It was studied the influence of the osmotic dehydration process using binary (water + NaCl) and ternary (water + NaCl + sucrose and water + NaCl + corn syrup) solutions in the convective drying of mapará catfish (Hypophthalmus edentatus). The influence of temperature, salt concentration, sugar concentration, immersion time on the responses of weight los

28. Identificação de resíduos de disparos de armas de fogo por meio da técnica de espectrometria de massas de alta resolução com fonte de plasma indutivo
The violence derived from crimes involving firearms represents one of the main concerns of society. For this reason modern techniques have emerged in forensic science to identify suspects at crime scenes. This work describes a methodology to identify residues present in the hands of suspect by using a high resolution inductively coupled plasma mass spectrome

29. Evaluation of the nitrate text in folhosas hortaliças produced by different systems of culture. / Avaliação do teor de nitrato em hortaliças folhosas produzidas por diferentes sistemas de cultivo.
Nitrate is naturally present in vegetables as a nitrogen source for their growth, the amount depending on genetic factors, the availability of this nutrient for the plant and environmental factors. It has been estimated that more than 70% of the nitrate ingested daily by man is supplied by vegetables. The present work evaluated the nitrate content in leafy v

30. Collection of acerola (Malpighia punicifolia L.) in passing processes using combined osmotic dehydration and drying / Obtenção de acerola (Malpighia punicifolia L.) em passa utilizando processos combinados de desidratação osmotica e secagem
In the present work it was studied the influence of the osmotic dehydration process using binary (sucrose+water) and ternary (sucrose+salt+water) solutions in the convective drying of acerola fruit (Malpíghía punícífolía L.). Pretreatments were evaluated by influences of immersion time (30 and 90 minutes), temperature (25 and 60°C) and sucrose concentr

31. Osmótica dehydration in ternary solutions, thermal drying and transistions of filé of tilápia (Oreochromis niloticus) / Desidratação osmotica em soluções ternarias, secagem e transições termicas de file de tilapia (Oreochromis niloticus)
In this work the osmotic dehydration in ternary solutions (NaCl-water-sucrose) and drying processes of Tilapia fillet (Oreochromis niloticus) were studied. Moreover the calorimetric study of impregnated fillet with sodium cWoride, sucrose or both solutes was developed and denaturation and glass transition temperatures were determined. The osmotic dehydration

32. Preparo e caracterização de microcapsulas obtidas por polimerização ionica para alimentação de larvas de peixe / Preparation and characterization of microcapsules obtained by polymerization Ionica feeding of fish larvae
This research aimed at producing microcapsules capable of retaining proteins, with the objective of substituting the live organisms used in larval fish feed. Four different polysaccharides: alginate, carrageenan, gelan gum and pectin were used, all having the capacity to form gels by ionic polymerization both individually and in association, in order to prod

33. Utilização de microemulsões como agentes modificadores de superfícies para remoção de íons metálicos
The heavy metals are used in many industrial processes and when discharged to the environment can cause harmful effects to human, plants and animals. The adsorption technology has been used as an effective methodology to remove metallic ions. The search for new adsorbents motivated the development of this research, accomplished with the purpose of removing C

34. Estabilidade de fases em ligas Mo-B-Si ricas em molibdenio
In recent investigations it has been proposed that equilibrium microstructures constituted by a refractory metal and an intermetallicphase are the best choice for high temperature structural applications at temperatures higher than 1400°C. Based on the information available in the literature it has been identified the existence of a Mo (solid solution) + in

35. SELF-ASSEMBLY AND COMPLEX PHASE BEHAVIOUR IN THE AMMONIUM PENTADECAFLUOROOCTANOATE / WATER / AMMONIUM CHLORIDE SYSTEM.
The ammonium pentadecafluorooctanoate in heavy water system (APFO/\ pot.2\ H\ ind.2\ O) exhibits exceptional phase behaviour stemming from strong tendency of the surfactant to form disc-like micelles which are stable over a wide concentration and temperature intervals. An understanding of this phase behaviour requires exposing the factors which govern the st
