1. Como diagnosticar o bruxismo na infância?
O diagnóstico do bruxismo do sono, em crianças, depende inicialmente do relato dos responsáveis, durante a anamnese odontológica, de sons produzidos como resultado do aperto durante a noite, bem como de sensibilidade dos dentes aos alimentos quentes ou frios, dor facial, dor de cabeça ou desconforto matinal queixados pelo paciente infantil. Ao exame

2. Chromosome diversity in Buthidae and Chactidae scorpions from Brazilian fauna: Diploid number and distribution of repetitive DNA sequences
Abstract In this work, we analyzed cytogenetically eight Chactidae and Buthidae, including the localization of repetitive DNA sequences. The chactids possess monocentric chromosomes and the highest diploid numbers (2n=50 in Brotheas amazonicus, 2n=36 in Chactopsis amazonica, 2n=30 in Neochactas sp.) when compared with buthids (2n=10 in Tityus bahiensis, 2n=1

3. ECG Signals Classification Using Overlapping Variables to Detect Atrial Fibrillation
ABSTRACT In the present work a method for the detection of the cardiac pathology known as atrial fibrillation is proposed by calculating different information, statistics and other nonlinear measures over ECG signals. The original database contains records corresponding to patients who are diagnosed with this disease as well as healthy subjects. To formulate

4. REFLEXIVITY, ROLE CONFLICTS, AND THE MEANING OF ENGLISH SELF PRONOUNS
Abstract This study offers an innovative, sign-based analysis of English self pronouns (myself, yourself, herself, etc.). While rejecting the traditional characterization of these forms as reflexive pronouns, the study borrows from the tradition by analyzing these forms as a kind of emphatic pronoun. The forms’ distribution can be explained by positing tha

5. Equipment for Monitoring Synchronous Generators Condition through External Magnetic Field Waveforms
Abstract This paper presents an equipment for monitoring synchronous generators condition through characteristics of the time derivative of the external magnetic field. The developed monitoring methodology allows the identification of established or incipient faults, by detecting changes in the magnetic signature of the synchronous generator. In this methodo

6. Estimation and Mapping of the Received Power Level of Digital Signals TV Using Spatial Interpolation Methods
Abstract The signal digitization process of the open television system is still in progress, therefore, the study of the digital signal propagation has great importance so that broadcasters can develop and improve the transmission service. The field measurement of digital signal parameters is one of the most reliable means to analyze the signal propagation i

7. Cascade Modeling of the Measuring System Used to Assess S-Parameters of Anchor Rods on Power Transmission Lines Guyed Towers
Abstract The structural condition of the cable-stayed towers anchorage on power transmission lines requires constant monitoring. Maintenance routines must be able to identify faulty anchor rods and substitute them to avoid tower collapses and power delivery interruptions. Modern statistical diagnostic systems based on machine learning requires the generation

8. Smartphone-Based Screening for Cardiovascular Diseases: A Trend?
Abstract Cardiovascular diseases are the leading cause of death in the world. People living in vulnerable and poor places such as slums, rural areas and remote locations have difficulty in accessing medical care and diagnostic tests. In addition, given the COVID-19 pandemic, we are witnessing an increase in the use of telemedicine and non-invasive tools for

10. Relationship between primary monosymptomatic enuresis and process toilet training: a case-control
ABSTRACT Objective: Primary monosymptomatic nocturnal enuresis (PMNE) is a prevalent condition in childhood, and the pathophysiology is multifactorial. This study investigated the relationship between the toilet training process (TT) and PMNE in children and adolescents. Patients and Methods: A case-control study was carried out from 2015 to 2020. The pres

11. Is there a change in P300 evoked potential after 6 months in cochlear implant users?
Abstract Objective: There are few studies on long-latency auditory evoked potential (P300) in people with hearing loss who use a cochlear implant. Central auditory system evaluation with behavioral and electrophysiological tests is believed to help understand the neuroplasticity mechanisms involved in auditory functioning after cochlear implant surgery.

12. Popular knowledge of stroke in São Paulo: a cross-sectional study within the World Stroke Campaign
ABSTRACT BACKGROUND: Stroke is the second leading cause of death in Brazil and the main cause of disability. Inability to identify alarm signals causes delays in seeking emergency services, thereby leading to a worse prognosis. OBJECTIVES: To assess the population's knowledge of how to recognize and prevent stroke. DESIGN AND SETTING: Prospective cross-se
