Evaluation of microstructural properties of ti-6al-7nb alloy for biomedical application

The choice of metallic materials for use in orthopedic and dental implants is made by evaluating physical, chemical and biocompatibility properties. Among these materials we highlight titanium-based alloys, such as those from the Ti-Al-Nb system, which have high chemical stability and biocompatibility attributed to the presence of niobium.

Four-year outcomes of aflibercept treatment for neovascular age-related macular degeneration: results from real-life setting

The authors are commenting on the study entitled: “Four-year outcomes of aflibercept treatment for neovascular age-related macular degeneration: results from rel-life setting” published by Lukic et al. in European Journal Ophthalmology 2020 (Doi: 10.1177/1120672120938565. Published on June 25, 2020), which assessed 4-year structural and functional outcomes in intravitreal aflibercept treatment for 89 patients (94 eyes) with neovascular age-related macular degeneration in a real-world setting.

Geodiversity and geoconservation in territorial dynamics: the example of the chapada diamantina - Bahia – Brazil

The occupation process of The Chapada Diamantina - located in the central part of the state of Bahia, Brazil - is directly associated with its peculiar Geodiversity, where geological and geomorphological aspects stands out. The region's growth was associated with two economic cycles: firstly, mineral exploration, which promoted the emergence of important cities and towns; and then what tries to explore the tourist possibilities of the Plate. It is worth noting that this second cycle is based on the roughness left by the first cycle, as well as on the scenic beauty, wells and waterfalls.

Analysis of pressures in a storage silo of bean cultivars with different types of steel

The Brazilian agricultural production exceeds the storage capacity, with that the construction of silo becomes essential, being the loads exerted by the product stored in the structure, the main factor for disasters in silos. In view of this, the present work aims to determine the pressures exerted by bean cultivars, according to EUROCODE 1.

Estudo numérico comparativo da potência disponível entre ondas regulares e irregulares: estudo de caso de um dispositivo de coluna de água oscilante na costa de rio grande – rs

A energia das ondas é um recurso pouco aproveitado, devido ao custo atual elevado de produção. Simulações realísticas do estado de mar são necessárias para avaliar a viabilidade e eficiência da instalação de dispositivos conversores da energia das ondas do mar em energia elétrica. Nesse contexto, o presente trabalho apresenta uma comparação da potência disponível em um conversor do tipo Coluna de Água Oscilante (CAO) quando submetido a ondas irregulares ou ondas regulares.

Epidemiological analysis and results from colonoscopies in patients from 84 municipalities between 2015 and 2019

Theaim of this study was to trace and describe the epidemiological profile of patientsundergoing colonoscopy through an observational cross-sectional cohort study whichfocused on patients from a macro region comprised of 84 municipalities in the inland of the state of São Paulo from 2015 to 2019. Results from 610 patients undergoing colonoscopy at the Regional Hospital of Jundiaíwere used to develop a comparative analysis betweenexam requests and main endoscopic findings, including prevalent colorectal pathologies.

Seed sweet potato production in aeroponics

The objective was to verify the possibility of the production of tuberous roots of sweet potatoes in an aeroponic systemin order to use these roots as seeds. The research was developed at the State University of Ponta Grossa (PR – Brazil). There were performed four attempts for the developing ofone aeroponic system in a greenhouse, involving experiments with structures and nutrient solutions for seven sweet potatoes genotypes.

Microbiological and physico-chemical quality of moist and natural pet foods sold in Brazil

This study evaluated the microbiological and physico-chemical quality of moist and natural foods for dogs and cats sold in Brazil. Three lots of 12 samples were collected, 4 correspond to diets categorized as economic, 2 for each species, 6 as premium, 2 feline and 4 canine, and 2 diets as natural, 1 for each species. The most pet foods analyzed are in accordance with the physico-chemical parameters, except the results of neutral and acid detergent fibre and fat values. All categories of pet foods evaluated comply with the maximum limit defined for coliforms at 45ºC.

Tratamento cirúrgico de queratocisto em região anterior de Maxila: Relato de caso

O queratocisto odontogênico é uma alteração patológica na cavidade íntra-óssea originária de resíduos da lâmina dental, possui caráter proliferativo lento e assintomático, dependendo do tamanho da lesão. O diagnóstico do queratocisto é um achado radiográfico, baseada na característica histopatológica. A descompressão é uma técnica elementar no tratamento conservador e mostra alta taxa de sucesso na literatura. O presente estudo tem como objetivo relatar um tratamento de queratocisto em região anterior da maxila, visando uma menor morbidade, através de um relato de caso clínico.
