1. O que é e o que define se um paciente deve ou não realizar cirurgia para catarata?
A catarata se caracteriza pela nebulosidade na lente do olho, levando a uma visão embaçada, comprometendo a qualidade de vida ou limitando as atividades do dia a dia, como ler e dirigir. A cirurgia é o único tratamento que, além de ser coberta pelo Sistema Único de Saúde (SUS), é recomendada pela Organização Mundial da Saúde (OMS) por ser a cat

2. Budbreak of pecan cultivars subject to artificial chill
ABSTRACT Chill is a limiting factor in commercial production of temperate fruit due to their dormancy mechanism. Thus, knowledge of chill requirements of cultivars is important to reach successful production. This study aimed at evaluating responses given by different pecan cultivars subject to artificial chill. Pecan branches were collected from twelve 9-ye

3. A novel fluorescence sensor for the detection of chloride ion in artificial sweat and environmental water with nitrogen-doped graphene quantum dots
A new fluorescent detection route for chloride ion was designed with Nitrogen-doped graphene quantum dots (N-GQDs), which were prepared by a traditional hydrothermal method with citric acid as carbon source and urea as nitrogen source. The prepared N-GQDs solution was light yellow, and the freeze-dried solid was black. It emitted blue light under ultraviolet

4. Light-Assisted Batch Injection Analysis of Glucose Exploiting a p-n-Homojunction Based on Cu2O
This work describes the development of a photoelectrochemical sensor for glucose quantification exploiting a light assisted-batch injection analysis (BIA) cell. A light-emitting diode (LED) lamp was employed to control the incidence of light on the p-Cu2O/n-Cu2O/fluorine-doped tin oxide (FTO) photoactive platform in BIA cell. The p-Cu2O/n-Cu2O/FTO platform w

5. Morphophysiological adjustments to shade of jaboticaba tree saplings
ABSTRACT We aimed to verify the morphophysiological changes in jaboticaba tree (Plinia peruviana (Poir.) Govaerts) saplings under shade gradient to improve knowledge on the appropriate light environmental conditions for the saplings production and field homogeneous or intercropping cultivation of this species. The saplings were grown under full sun and artif

6. PERFORMANCE AND WELFARE OF FINISHING PIGS SUBJECTED TO CLIMATECONTROLLED ENVIRONMENTS AND SUPPLEMENTARY LIGHTING
ABSTRACT An adequate thermal environment in pig farming facilities is essential to ensure productivity and animal welfare. The objective of this study was to evaluate the behavior and performance of finishing pigs, subjected to climate-controlled environments and supplementary lighting. Twenty-seven pigs (3/4 Duroc, 1/4 Pietrain) were kept in pens with no cl

7. Inverse Design of Tapers by Bio-Inspired Algorithms
Abstract The efficiency of optical power transferred between two bidimensional waveguides, continuous waveguide and periodic subwavelength waveguide has been designed and optimized by using a taper composed by variable length segments (0.03 − 0.27 µm). Waveguides with variable width (270 − 330 nm) have been considered and the number of segments on the t

8. THE VALO GRANDE CHANNEL IN THE CANANÉIA-IGUAPE ESTUARY-LAGOON COMPLEX (SP, BRAZIL): ENVIRONMENTAL HISTORY, ECOLOGY, AND FUTURE PERSPECTIVES
Resumo Inaugurado em 1852, o canal artificial do Valo Grande (VG), no rio Ribeira de Iguape (SP), configura-se como um dos maiores desastres ambientais da costa brasileira. Este artigo apresenta uma síntese sobre o tema, abordando suas dimensões histórica, ecológica, geográfica e sociopolítica. O VG tem causado a desestruturação do ecossistema e a re
