1. Gestantes podem ser submetidas a radiografias durante o tratamento odontológico?
As radiografias odontológicas são consideradas seguras para as mulheres grávidas em qualquer período da gestação
. Entretanto, o profissional deve utilizar todas as medidas de precaução: utilizar o avental de chumbo e o protetor de tireoide, utilizar filmes radiográficos ultrassensíveis (filme E) e de menor tempo de exposição e evitar ra

2. Functional status of individuals with osteogenesis imperfecta: data from a reference center
Abstract Objective: To evaluate the functional status of individuals with Osteogenesis Imperfecta (OI) followed up at a reference center in the state of Bahia. Materials and methods: This is an observational, cross-sectional, descriptive study, which evaluated individuals with OI, based on a non-probabilistic sampling. To assess motor function, the Motor F

3. Prevalence of thyroid dysfunction in neonates receiving parenteral nutrition in the intensive care unit
Abstract Objective: The use of parenteral nutrition (PN) formulations that do not contain iodine can contribute to the deficiency of this mineral, potentially leading to hypothyroidism and, ultimately, neurocognitive impairments. This study aimed to evaluate TSH alterations in newborns receiving PN. Methods: Retrospective study of neonatal intensive care u

4. Bullous Melanoma: should the thickness of the bullous lesion be included in Breslow depth measurement?
Abstract Bullous melanoma represents a rare variant of melanoma, especially in patients without underlying bullous cutaneous disease. Few cases have been described in the literature, including cases of melanoma in patients with bullous epidermolysis or Hailey-Hailey disease. The histopathological diagnosis of bullous melanoma does not show any difficulties,

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. The nutritional status of healthy children using bioelectrical impedance and anthropometric measurement
Abstract Objective: Monitoring of healthy children should include precise assessment of their nutritional status to identify children and adolescents at risk of nutrition disorders. Therefore, the aim of this study was to assess the nutritional status of healthy children using different nutritional risk screening tools. Method: The study sample consisted o

7. MIMO-PLC Communications in an Experimental Medium Voltage Network: Measurement and Analysis
Abstract This paper presents measurements at a mock-up medium voltage network to verify the feasibility of Broadband Power Line Communication (BPLC). We use the data extracted within the frequency range 2 − 30 MHz to characterize a MIMO PLC network using different phase combinations, defining the best and worst use case scenarios. The empirical data shows

8. Determination of Electric and Magnetic Field Calculation Uncertainty in the Vicinity of Overhead Transmission Lines
Abstract This paper presents a new approach for uncertainty determination of the electric field intensity and magnetic flux density calculation in the vicinity of overhead transmission lines. The proposed method is based on the law of propagation of uncertainty as defined in the Guide to the expression of Uncertainty in Measurement. A mathematical model is d

9. Allometric models for estimating the leaf area of lisianthus (Eustoma grandiflorum) using a non-destructive method
ABSTRACT Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in the post-harvest. The leaf area measurement is fundamental in plants because the leaves are directly related to several processes such as transpiration, radiation interception and CO2 fixation that enable the plant to grow. The objective of t

10. Design and Implementation of Microwave Dual-Band Pass Interdigital Filter Using an Analytical Approach
Abstract In this paper, benefiting from frequency transformation between the normalized frequency domain of low-pass prototype frequencies and the real frequency domain of the filter, a purely analytical procedure for dual-band filter design is used. The coupling matrix of the filter is analytically extracted, without the need to perform numerical optimizati

11. An inconvenient status in anti-osteoporotic treatment process: corticosteroid use
SUMMARY OBJECTIVE: There are limited studies investigating the comparison of the efficacy of anti-osteoporotic drugs in different conditions resulting in osteoporosis in older adults. This study aimed to compare the effectiveness of anti-osteoporotic agents in older adults with or without glucocorticoid-induced osteoporosis. METHODS: This retrospective stu

12. AOPs são o futuro da ecotoxicologia?
ARE AOPs THE FUTURE OF ECOTOXICOLOGY? AOPs (Adverse Outcome Pathways) were introduced in the field of ecotoxicology due to the need of replacement of the classic system for assessing adverse results (considering only the mortality of organisms exposed to certain substances or mixtures) to a predictive system based on the measurement of biological events occu
