1. Evaluation of OSEB and SEBAL models for energy balance of a crop area in a humid subtropical climate
ABSTRACT This study evaluated the adequacy of the One-Source Energy Balance (OSEB) and Surface Energy Balance Algorithm for Land (SEBAL) models to estimate evapotranspiration in grain growing areas with humid subtropical climate in Rio Grande do Sul, southern Brazil. The dataset was obtained from a micrometeorological station (Eddy Covariance) and MODIS (Mod

2. Estudo do campo de radiação neutrônica em torno do cíclotron GE PETtrace-8 de 16,5 MeV do CDTN / Study of the neutron radiation field around the GE-PETtrace-8 cyclotron do CDTN
Os radionuclídeos utilizados na tomografia por emissão de posítrons (PET) são produzidos utilizando um acelerador cíclotron. Os nêutrons produzidos durante a operação do cíclotron contribuem para exposição direta ou indireta dos Indivíduos Ocupacionalmente Expostos (IOEs), devido ao aumento da radiação de fundo da casamata. Além disso, há um

3. Caracterização da relaxação por compressão de borracha acrílica irradiada. / Compression relaxation characterization of irradiated acrylic rubber.
Este trabalho tem como objetivo investigar a redução da relaxação por compressão de borracha acrílica modificada (ACM) irradiada por feixe de elétrons, através da caracterização de seu comportamento mecânico e de sua estrutura molecular. O material, nas condições original e irradiado, foi inicialmente submetido a ensaios uniaxiais de tração e

4. Estudo prospectivo randomizado do tratamento endoscópico da coloproctopatia actínica crônica hemorrágica: eletrocauterização com plasma de argônio versus bipolar. / Randomized and prospective study of endoscopic treatment to hemorrhagic chronic radiation coloproctopathy: argon plasma eletrocauterization versus bipolar.
Introduction: Chronic radiation coloproctopathy (CRCP) is a well-recognized complication of radiotherapy. Rectal bleeding is the most common symptom of radiation injury and the optimal endoscopic treatment of bleeding due to CRCP is still controversial. Aim: To compare the efficacy and safety of bipolar eletrocauterization (BEC) and argon plasma eletrocauter

6. Evaluation of parameters associated with UV/EB cured clearcoats degradation used in outdoor environment / Avaliação da formação e degradação de filmes de vernizes curados por radiação ultravioleta e feixe de elétrons e expostos ao envelhecimento acelerado
The materials curable by ultraviolet (UV) or electron beam (EB) radiation such as inks, adhesives and coatings are reactive compounds made up of resin, monomer, photoinitiator and additives which undergo polymerization and crosslinking under irradiation producing thermoset products. This technology has been used in a great variety of industrial applications,

7. Intraoperative radiation therapy following pancreaticoduodenectomy.
OBJECTIVE: To determine the morbidity and mortality of pancreaticoduodenectomy followed by electron-beam intraoperative radiation therapy (EB-IORT). SUMMARY BACKGROUND DATA: Local recurrence following pancreaticoduodenectomy occurs in 50% to 90% of patients who undergo a potentially curative surgical resection for adenocarcinoma of the pancreatic head. To im

8. Heterogeneity of thymic epithelial cells in promoting T-lymphocyte differentiation in vivo.
To study in vivo the contribution of different thymic epithelial cells to T-lymphocyte differentiation, we have established several nontransformed thymic epithelial cell lines and developed an in vivo assay, not involving exposure to drugs or radiation, that permitted us to study the capacity of these epithelial lines to support T-cell differentiation. We fo
