1. Validation of a classification and scoring system for the diagnosis of laryngeal and pharyngeal squamous cell carcinomas by confocal laser endomicroscopy
Abstract Introduction: Confocal laser endomicroscopy is an optical imaging technique that allows in vivo, real-time, microscope-like images of the upper aerodigestive tract’s mucosa. The assessment of morphological tissue characteristics for the correct differentiation between healthy and malignant suspected mucosa requires strict evaluation criteria. Ob

2. The aquatic species Pontederia azurea and P. crassipes (Pontederiaceae) in the Pantanal, Brazil: evidence of how plant structure can simultaneously reflect phylogeny and ecology
ABSTRACT Hydric fluctuations in the Pantanal comprise annual dry and wet seasons that modify local diversity and plant morphology and anatomy. Widespread in this wetland are the sympatric Pontederia azurea and P. crassipes, which, although primarily aquatic, can also develop in non-flooded environments. This study undertook a comparative investigation of the

3. LAPAROSCOPIC DISTAL PANCREATECTOMY WITH OR WITHOUT SPLEEN PRESERVATION: COMPARATIVE ANALYSIS OF SHORT AND LONG-TERM OUTCOMES
RESUMO Racional: Pancreatectomia distal laparoscópica (PDL) é a abordagem de escolha para ressecção de tumores no pâncreas distal devido a suas muitas vantagens sobre a abordagem laparotômica. Objetivo: Analisar e comparar os resultados em curto e longo prazo da PDL realizada por meio de duas técnicas diferentes: com esplenectomia vs. preservaç

4. IMPROVEMENT OF METHANE STORAGE CAPACITY IN ACTIVATED CARBON BED WITH BIDISPERSE PACKING
Abstract This study presents a numerical investigation of the dynamics of methane adsorption in granular activated carbon beds with bidisperse packing in order to reduce the void spaces between the adsorbent particles and to improve the storage capacity in adsorbed natural gas vessels. Two distinct particle sizes (d and D) were used for the packing of the bi

5. ON THE PERFORMANCE OF DIFFERENT RANS BASED MODELS TO DESCRIBE THE TURBULENT FLOW IN AN AGITATED VESSEL USING NON-STRUCTURED GRIDS AND PIV VALIDATION
ABSTRACT The performances of the Standard κ-ε, RNG, Realizable, κ-ω and RSM turbulence models to describe the behavior of the flow in agitated tank reactors were evaluated. Because most of these tanks have complex geometries, structured meshing schemes are not a practical alternative in engineering. Two particular unstructured meshing schemes composed of

7. SAFETY AND EFFICACY OF EUS-GUIDED COIL PLUS CYANOACRYLATE VERSUS CONVENTIONAL CYANOACRYLATE TECHNIQUE IN THE TREATMENT OF GASTRIC VARICES: A RANDOMIZED CONTROLLED TRIAL
RESUMO CONTEXTO: Uma das complicações mais temidas com o uso de cianoacrilato para tratamento de varizes gástricas é a ocorrência de embolia sistêmica potencialmente fatal. Assim, os endoscopistas estão se aprimorando com novas técnicas, incluindo o uso de coils endoscópico, como uma opção de tratamento potencialmente mais segura e eficaz. No en

8. Relevance of wood anatomy and size of Amazonian trees in the determination and allometry of sapwood area
RESUMO Processos hidrológicos de povoamentos florestais são predominantemente influenciados pela composição de espécies arbóreas e suas características morfo-fisiológicas. No entanto, existem poucos estudos sobre os padrões anatômicos que determinam o sistema hidráulico de plantas em ecossistemas tropicais. Por isso, nosso objetivo foi o de analis

9. First evaluation of semidirect recycling methods for the reclamation of cemented carbides based on a literature survey
ABSTRACT At the moment the industrially applied techniques for cemented carbide reclamation feature several deficiencies. Depending on the process route, obstacles consist in high energy and chemical consumption (indirect recycling methods) or a deterioration of the recycled product in comparison with the primary material (direct recycling approach). Therefo

10. Comparative evaluation between mechanical and pneumatic cells for quartz flotation in the iron ore industry
Abstract Flotation plays a relevant role in the concentration of iron ores. Conventional flotation technology employing mechanical machines and columns and also circuits combining both types of cells have been utilized in the iron ore industry. The top size of particles in the flotation circuit feed is 150 µm and the slimes below 10 µm are removed as overf

12. Humpback whale Megaptera novaeangliae (Cetartiodactyla: Balaenopteridae) group sizes in line transect ship surveys: An evaluation of observer errors
ABSTRACT Accurate estimates of group sizes through line transect sampling methods are important to correctly ascertain the abundance of animals that occur in groups. Since the average observed group size is a component of the distance sampling formula, bias in these data leads to biased abundance estimates. This study aimed to evaluate the potential errors i
