1. Evening chronotype as a bipolar feature among patients with major depressive disorder: the results of a pilot factor analysis
Objectives: The bipolar spectrum concept has resulted in a paradigm shift that has affected both the diagnosis and therapy of mood disorders, with bipolarity becoming an indicator of treatment resistance in depression. Evening circadian preference has also been linked to affective disorders. The aim of our study was to confirm the relationship between the se

2. Multimodal Neuromonitoring During Pediatric Cardiac Surgery
Abstract Introduction: Neuromonitoring (electroencephalogram [EEG] and cerebral oximetry) is essential for appropriate anesthesia and neuroprotection assessment during pediatric cardiac surgery. Methods: We describe the intraoperative pediatric multimodal and multiparametric neuromonitoring pattern of the software system Neuron-Spectrum (Kandel®) that con

5. Effect of Quiet and Noise on P300 Response in Individuals with Auditory Neuropathy Spectrum Disorder
Abstract Introduction Auditory neuropathy spectrum disorder (ANSD) is a clinical condition in which individuals have normal cochlear responses and abnormal neural responses. There is a lack of evidence in the literature regarding the neural discrimination skill in individuals with ANSD, especially when the signal is presented in the presence of noise. Obje

6. INTERACTIONS BETWEEN ADJUVANTS AND THE FUNGICIDE AZOXYSTROBIN+BENZOVINDIFLUPYR IN HYDRAULIC SPRAYING
ABSTRACT Adjuvants are tools to maximize pesticide spray quality. This study aimed to evaluate the interaction effects between adjuvants and the fungicide azoxystrobin + benzovindiflupyr on the physicochemical characteristics, droplet evaporation time, and spray droplet size. The experiment was carried out using a 2×6 factorial scheme, in which the first fa

7. SPECTRUM AND VELOCITY OF DROPLETS OF SPRAY NOZZLES WITH AND WITHOUT AIR INDUCTION
ABSTRACT The aim of this study was to evaluate the spectrum and the velocity of droplets produced by nozzles with and without air induction, under different pressures and flow rates. The experiment was conducted in a completely randomized design with five replications, in a factorial 2 x 3 x 3 (two spray nozzles, three flow rates and three operating pressure

8. Benign familial fleck retina: estudo multimodal incluindo OCT angiography
RESUMO O objetivo do presente relato é demonstrar um estudo multimodal de um paciente com diagnóstico de Benign Familial Fleck Retina (BFFR) (OMIM 228980), uma alteração retinana muito rara. Retinografia colorida demonstrou “flecks” na retina posterior ao equador, poupando mácula. Tanto autofluorescência quando imagem “infrared,” nota-se padrã

9. Discerning the Fatigue Crack Growth Behavior of API X65 Steels Under Sequence Loading
Abstract This paper presents the effect of sequence loading on fatigue crack growth of API X65 steel tested in room temperature. Most of pipeline steels are subjected to wide spectrum of loading during the length of service. Influence of load history effect can cause a trickier assessment to the fatigue behaviour. The objective of this study is to determine

10. Avaliação da propagação de trinca associada à corrosão da liga 7475 T7351 submetida a carregamentos de voos simulados / Evaluation of corrosion fatigue crack growth for 7475 T7351 alloy under spectrum loading
A análise da vida em fadiga em amplitude variável associada à corrosão é bastante complexa, devido a combinações entre as interações eletroquímicas ocorridas, tendo em vista a exposição da frente da trinca à névoa salina somada aos efeitos deletérios do carregamento de amplitude variável. Esta combinação de efeitos ainda não é modelada ma

11. Avaliação dos efeitos de exercícios vocais em vozes normais com análise perceptivo-auditiva, acústica e de imagens laríngeas obtidas por videolaringoscopia de alta velocidade / Immediate effects of vocal exercise in normal voices using perceptual, acoustic analysis and of the high-speed videolaryngoscopy images
The aim is to detect the immediate effect of vocal exercises in normal voices. Thirty healthy subjects from 19 to 45 year old with no vocal complains participated in the study. The sustained vowels /a/ and /E/ were recorded in two moments: the first, we recorded the habitual voice, before any exercises; and the second, after from 1 to 5 minutes of continuous

12. Tecnologia de aplicação aérea e terrestre na cultura da batata / Aerial and ground application technology in potato crop
A batata é a principal olerícula cultivada no Brasil, porém apresenta grandes desafios quanto à tecnologia de aplicação de fitossanitários. A alta frequência de aplicações desses produtos, principalmente fungicidas, é a grande responsável pelo seu elevado custo de produção. Dessa forma, é necessário estudar métodos que otimizem a tecnologia
