1. Violent behavior, perceived safety, and assault experiences among adolescents: results from the Brazilian National Adolescent School-based Health Survey
Objective To investigate factors associated with violent behavior in a large nationally representative sample of Brazilian adolescents. Methods The data were derived from the 2015 National Adolescent School-based Health Survey (Pesquisa Nacional de Saúde do Escolar [PeNSE]). The independent variables of interest included feelings of safety while on the way

2. ARTEMISININA E DERIVADOS: DESCOBERTA, ESTRATÉGIAS SINTÉTICAS E OBTENÇÃO INDUSTRIAL
Artemisinin, a natural sesquiterpene isolated from the Artemisia annua L. plant, represents a remarkable achievement in the treatment against malaria. Since its discovery in the 1970’s, researchers readily started synthesizing this complex natural product containing an unusual endoperoxide fragment. Despite various total syntheses reported, only in the las

3. Phase Adjustment of S-Parameters from Coupled Resonator Filters
Abstract This paper presents a method to cancel the constant phase loading and transmission line that are added to the S-parameters of coupled resonant networks. Thus, the phase-corrected S-parameters may be used to obtain a rational model together with its representative coupling matrix. This method is applicable to lossy and lossless coupled resonator netw

4. Unveiling the Bacterial Sesquiterpenome of Streptomyces sp. CBMAI 2042 Discloses Cyclases with Versatile Performances
Terpenes are the most abundant class of natural product that exist in nature. They possess a myriad of industrial applications including pharmaceutical, perfumery and flavors, bulk chemicals, and fuel. Intriguingly, until today, the vast majority of characterized terpenoids have been isolated from plants and fungi, and only in recent years bacteria were foun

5. RECENT ADVANCES IN CYANATION REACTIONS
Transformations involving structurally complex molecules, natural products and representative molecules are extremely important to obtain key reaction intermediates, in addition to accessing molecules with bioactive properties. The development of cyanation methodologies in those molecules becomes important, because nitriles are versatile and important buildi

6. Testing the consumption-based CAPM using the stochastic discount factor
Abstract This article investigates the problem of optimal intertemporal consumption in the CCAPM setup from a new empirical perspective. The econometric analysis is based on use of the equality between the stochastic discount factor (SDF) and the marginal rate of intertemporal substitution of consumption, which in the CCAPM is equivalent to the Euler equatio

7. Olfactory Performance among Hospital Residents
Abstract Introduction Smell plays an important role in the maintenance of health and quality of life of the general population. Health workers with olfactory impairment may not be able to help diagnose certain diseases, and subsequently increase the risk of hazardous events and mortality among those affected. ‘Odor learning’ requires repeated experience

8. Does physical activity moderate the association between device-measured sedentary time patterns and depressive symptoms in adults?
Objectives: To investigate the association between sedentary time (ST) patterns and depressive symptoms, and whether moderate-to-vigorous physical activity (MVPA) can moderate this association. Methods: This cross-sectional study included a representative sample of 243 adults (mean age 41.8±16.7 years, 56.4% women) from a city in Southeast Brazil. Depressi

9. Barriers to physical activity among adults in primary healthcare units in the National Health System: a cross-sectional study in Brazil
ABSTRACT BACKGROUND: Many factors may negatively impact physical activity (PA), but studies lack evidence of individual predictors of perceived barriers to PA among adults in primary healthcare units. OBJECTIVE: To analyze associations between sociodemographic characteristics, health conditions, leisure-time physical activity (LTPA), PA counseling and perc

10. Projeções de vazão para avaliação de estimativa de carga de nutrientes afluentes à lagoa Mangueira, Rio Grande do Sul, em cenários de mudanças climáticas do Quinto Relatório de Avaliação das Mudanças Climáticas
RESUMO As mudanças climáticas podem causar alterações drásticas nos ecossistemas lacustres especialmente em razão da elevação da temperatura e das alterações na precipitação, provocando, entre outros fatores, aumento no aporte de nutrientes e, consequentemente, eutrofização. Este trabalho apresenta a estimativa de projeções de vazão e carga

11. Accuracy of the Simplified Version of the Global Risk Score in Detecting Cardiovascular Risk in Women from Quilombola Communities in the State of Alagoas, Brazil
Abstract Background: Cardiovascular risk (CVR) monitoring is important for defining preventive actions against cardiovascular disease; this condition prevails more intensely in scenarios with less infrastructure such as African descent communities. The Framingham Risk Score (FRS) and the Global Risk Score (GRS) have been used in Brazil for CVR monitoring ba

12. Associations between countertransference reactions towards patients with borderline personality disorder and therapist experience levels and mentalization ability
Abstract Objective This exploratory study locates countertransference as a pan-theoretical concept, comprising of thoughts, feelings, and behaviors expressed or experienced by therapists toward their patients. It aims to understand the patterns of countertransference experienced in working with borderline personality disorder. Associations between countert
