1. Wnt3a but not CDX-2 expression is associated with differentiated thyroid cancer
SUMMARY OBJECTIVE: Thyroid neoplasm incidence has increased worldwide, mostly due to the advancements in medical imaging and screening rates. The aberrant Wnt/β-catenin pathway has been identified as a key mechanism, and it has also been related to the metastatic activity of differentiated thyroid cancer. We aimed to verify the difference in the expression

2. “Infrastructural geopolitics” of climate knowledge: the Brazilian Earth System Model and the North-South knowledge divide
Resumo Este artigo examina como a geopolítica se insere nos esforços das nações do Sul de construção de novas infraestruturas de conhecimento climático. Para tanto, analisa-se a composição da base internacional de modelagem climática do Painel Intergovernamental sobre Mudanças Climáticas (IPCC), sob a perspectiva do Modelo Brasileiro do Sistema T

3. Grade uncertainty embedded in long term scheduling: stochastic mine planning
Abstract The inclusion of grade uncertainty for multivariate mineral deposits is of great importance for the correct management of subsequent decisions involved in mining planning. Mapping grade uncertainties allows maximization of profit and resource extraction. In this article, the co-simulation turning band algorithm is applied with the aim of predicting

4. Monitoramento de Longo Prazo e Climatologia de Campos Estratosféricos quando da Ocorrência dos Eventos de Influência do Buraco de Ozônio Antártico sobre o Sul do Brasil
Resumo O monitoramento de longo prazo dos eventos de Influência do Buraco de Ozônio Antártico sobre o Sul do Brasil foi realizado no período de 35 anos entre 1979 e 2013 e calculada a climatologia e anomalias dos campos estratosféricos quando de sua ocorrência. Para isso, foram analisados os dados da coluna total de ozônio (CTO) obtidos através de Es

5. Influence of the geometry of nanostructured hydroxyapatite and alginate composites in the initial phase of bone repair
Abstract Purpose: To analyze, histomorphologically, the influence of the geometry of nanostructured hydroxyapatite and alginate (HAn/Alg) composites in the initial phase of the bone repair. Methods: Fifteen rats were distributed to three groups: MiHA - bone defect filled with HAn/Alg microspheres; GrHA - bone defect filled with HAn/Alg granules; and DV - e

6. PRODUCTIVE RESPONSES FROM BROILER CHICKENS RAISED IN DIFFERENT COMMERCIAL PRODUCTION SYSTEMS - PART I: FUZZY MODELING
ABSTRACT Broiler chickens are classified as homoeothermic animals and require a production environment within well-defined thermal comfort intervals. Therefore, the development of algorithms (mathematical models) to control the environment that can be embedded in microcontrollers becomes necessary. Hence, this work aimed to develop a fuzzy model for predicti

7. Comunicação da morte: modos de pensar e agir de médicos em um hospital de emergência
Resumo Este estudo objetivou compreender como os médicos lidam com o processo de comunicar a morte aos familiares em um hospital de emergência. Trata-se de uma pesquisa qualitativa, embasada na antropologia interpretativa e médica. A coleta dos dados deu-se em um dos maiores hospitais públicos de emergência da América Latina, ao longo de nove meses de

8. Territórios e alianças políticas do pós-ambientalismo
RESUMO O objetivo deste artigo é contribuir com o debate acerca do desmatamento no contexto da evolução das políticas de gestão fundiária e territorial na Amazônia, destacando seu papel relevante para o reconhecimento de direitos políticos de categorias sociais minoritárias. A associação do desmatamento na Amazônia sempre esteve correlacionada a

9. Polydimethylsiloxane as a Matrix for the Stabilization and Immobilization of Zero-Valent Iron Nanoparticles. Applications to Dehalogenation of Environmentally Deleterious Molecules
A wet-synthetic method is described to obtain magnetic, air-stable, zero-valent iron nanoparticles coated with an alkanedioic acid. The particles can be immobilized in an amino-substituted polysiloxane matrix to provide materials capable of dechlorinating, debrominating, and deiodinating a wide variety of halogenated organic molecules dissolved initially in

10. All-Optical Logic Gates Devices based on SPP Coupling between Graphene Sheets
Abstract The aim of this work is to propose all-optical logic gates based on surface plasmon polaritons (SPP's) coupling among spatially separated graphene sheets. This model consists of graphene nanoribbons embedded in silica (SiO2) substrate place in a distance such that allow an efficient coupling between the plasmonic modes of the waveguides. It was nume

11. Improving short-term grade block models: alternative for correcting soft data
Abstract Short-term mining planning typically relies on samples obtained from channels or less-accurate sampling methods. The results may include larger sampling errors than those derived from diamond drill hole core samples. The aim of this paper is to evaluate the impact of the sampling error on grade estimation and propose a method of correcting the impre

12. Application of Short Fibers Reinforced Composites in Power Transmission Coupling
Abstract In this study the use of short glass, carbon and hybrid glass-carbon fibers reinforced polymeric composites in power transmission coupling is investigated. The presented work is generalized to thermoplastic and thermoset polymeric matrix composites. The effects of the constituents weight percentages, and average fibers length on the composite tensil
