13. How do stress, sleep quality, and chronotype associate with clinically significant depressive symptoms? A study of young male military recruits in compulsory service
Objective: Although studies have shown an association between poor sleep and chronotype with psychiatric problems in young adults, few have focused on identifying multiple concomitant risk factors. Methods: We assessed depressive symptoms (Beck Depression Inventory [BDI]), circadian typology (Morningness-Eveningness Questionnaire [MEQ]), sleep quality (Pit

14. Egg quality of laying hens fed diets with plant extracts
ABSTRACT. The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was

15. Automatic calibration of a large-scale sediment model using suspended sediment concentration, water quality, and remote sensing data
RESUMO A calibração e a validação são duas etapas importantes na aplicação de modelos de sedimentos que requerem dados observados. Nesse contexto, este estudo investigou o potencial de uso dos dados de concentração de sedimentos em suspensão (CSS), qualidade da água e sensoriamento remoto na calibração e validação de um modelo hidrossedimentol

16. Managing severe tuberculosis and its sequelae: from intensive care to surgery and rehabilitation
RESUMO A tuberculose multirresistente e a tuberculose extensivamente resistente ainda são um desafio para médicos e especialistas em saúde pública. Os desfechos globais do tratamento ainda são insatisfatórios; apenas 54% dos pacientes têm um desfecho positivo. Os desfechos globais são ainda piores em pacientes infectados por cepas altamente resistent

17. Structural Health Monitoring of Sandwich Structures Based on Dynamic Analysis
Abstract This work aims to contribute to the development of SHM systems based on vibration methods to be applied on sandwich structures. The main objective is focused on experimental damage identification via changes in the Frequency Response Function (FRF) with the usage of damage metrics. Specimens of sandwich structures made from skins of epoxy resin rein

18. Expert-Driven and Citational Approaches to Assessing Journal Publications of Brazilian Political Scientists
In this study, we seek to contribute to discussions on how the quality of academic production in the field of political science should be evaluated using Brazil as a case study. We contrast the 'expert-driven approach' that is followed by CAPES, an agency of the Brazilian federal government with the 'citational' approach, which is based on the ranking of jou

19. A wavelet-based method for power-line interference removal in ECG signals
Abstract Introduction The analysis of electrocardiogram (ECG) signals allows the experts to diagnosis several cardiac disorders. However, the accuracy of such diagnostic depends on the signals quality. In this paper it is proposed a simple method for power-line interference (PLI) removal based on the wavelet decomposition, without the use of thresholding t

20. APPLICABILITY OF AN ASSESSMENT MODEL FOR HEALTHCARE INFORMATION SYSTEMS IN A PUBLIC HOSPITAL
ABSTRACT Assessment processes are essential to guarantee quality and continuous improvement of software in healthcare, as they measure software attributes in their lifecycle, verify the degree of alignment between the software and its objectives and identify unpredicted events. This article analyses the use of an assessment model based on software metrics fo

21. Sensitivity analysis of ordinary kriging to sampling and positional errors and applications in quality control
Abstract Data quality control programs used in the mineral industry normally define tolerance limits based on values considered as good practice or those that have previously been applied to similar deposits, although the precision and accuracy of estimates depend on a combination of geological characteristics, estimation parameters, sample spacing and data

22. Assessing biomass based on canopy height profiles using airborne laser scanning data in eucalypt plantations
This study aimed to map the stem biomass of an even-aged eucalyptus plantation in southeastern Brazil based on canopy height profile (CHPs) statistics using wall-to-wall discrete return airborne laser scanning (ALS), and compare the results with alternative maps generated by ordinary kriging interpolation from field-derived measurements. The assessment of st
