13. Estudo da desidratação osmotica com aditivos e do acondicionamento sob atmosfera modificada de pedaços de mamão formosa / Study of osmotic dehydration with additives and of the packaging under modified atmosphere of Formosa papaya pieces.
Modern life style, allied to an interest for a healthy diet, has been causing a market demand for fresh-like foods, ready for consumption and convenience. In response to this demand the food industry promoted the development of mild processes and technologies, aiming to maintain product final quality and increase its resistance to degradation. Papayas from t

14. Fresh-cut strawberry stored under refrigeration and controlled atmosphere / Morango processado minimamente e conservado sob refrigeração e atmosfera controlada
Strawberries are a temperate vegetable crop highly appreciated by consumers due to their unique characteristics such as bright red color, soft texture and slightly acidified flavor. Due to their high demand both at national and international level, the development of fresh-cut technology for strawberries is highly desirable. The present work was carried out

15. Estudos e desenvolvimento de processos de pós condensação no estado sólido do PET reciclado / Studies and development of solid state polymerization process on poly(ethilene terephalate) recycled abstract
The increasing requirement of Ply(ethylene terephtalate) PET from the package market has made this available to the public discarded, quickly, since the technology of multi way package hasnt been possible due to high cost on the plant and its inadequate reuse. In the PET mechanical recycling, the most used way worldwide to recovery this material, the feature

16. Melhor dose e dose econômica de TBHQ nos óleos de milho e canola. / Best and economical doses of tbhq in corn and canola oils.
The increasing utilization of PET packaging in the last years in Brazil has concerned oil producers regarding oxidation. In this work, corn and canola oils, free from antioxidants and citric acid, were added of different TBHQ concentrations, and submited to accelerated (thermo and light induced) oxidation in a Schaal oven test at 63 0 C for 120 hours and in

17. Tecnologia solar de interesse social e baixo custo para aquecimento de agua na moradia
Low cost technological solutions are defined here as practices that ally thermal efficiency and low investments for the economical and social context of low income populations. These solutions imply in the use of low cost recyde materials and row materials. The present work analyses solar heat water technologies for Brazilian poor people, faced their energet

18. A espectrometria de fluorescencia de raios-X de energia dispersiva na medida de espessura de filmes polimericos e filmes metalicos espessos
In modern technology there is an increasing need for materials with thickness in nanometer ranges. Energy Dispersive X-Ray Fluorescence Spectrometry (EDXRF) can be considered an important tool for measurements in this range, since the intensity of the elemental X-ray line in a thin film is proportional to its thickness. In this work the purpose was to analyz

19. Breast imaging technology: Recent advances in imaging endogenous or transferred gene expression utilizing radionuclide technologies in living subjects - applications to breast cancer
A variety of imaging technologies is being investigated as tools for studying gene expression in living subjects. Two technologies that use radiolabeled isotopes are single photon emission computed tomography (SPECT) and positron emission tomography (PET). A relatively high sensitivity, a full quantitative tomographic capability, and the ability to extend sm

20. Positron emission tomography provides molecular imaging of biological processes
Diseases are biological processes, and molecular imaging with positron emission tomography (PET) is sensitive to and informative of these processes. This is illustrated by detection of biological abnormalities in neurological disorders with no computed tomography or MRI anatomic changes, as well as even before symptoms are expressed. PET whole body imaging i

21. Effectiveness of positron emission tomography for the detection of melanoma metastases.
OBJECTIVE: The purpose of this study was to determine the sensitivity, specificity, and clinical utility of 18F 2-fluoro-2-deoxy-D-glucose (FDG) total-body positron emission tomography (PET) scanning for the detection of metastases in patients with malignant melanoma. SUMMARY BACKGROUND DATA: Recent preliminary reports suggest that PET using FDG may be more

22. Efficient in situ electroporation of mammalian cells grown on microporous membranes.
Electroporation is a common technique for the introduction of DNA molecules into living cells. The method is currently limited by the necessity of applying the electrical discharge to cells in suspension. Adherent cells must therefore be removed from their substratum, which can induce unwanted physiological effects. We report here a new procedure for in situ
