1. Genital ulcers caused by sexually transmitted agents,
Abstract Genital ulcers (GUs) represent a diagnostic challenge and can be secondary to neoplastic and inflammatory processes of different causes. Among those of infectious etiology, there are sexually transmitted infections (STIs), a very frequent reason for seeking the health service. The most common agents are herpes simplex virus and Treponema pallidum an

2. USE OF REMOTELY PILOTED AIRCRAFTS FOR THE APPLICATION OF PLANT PROTECTION PRODUCTS
ABSTRACT The use of remotely piloted aircrafts (RPAs) to apply plant protection products has grown a lot in agriculture worldwide. However, little research data are available regarding the efficiency and safety of this method, especially in Brazil. Thus, this review aimed to present the current scenario of scientific research involving RPAs in the applicatio

3. Performance of Water Oxidation by 3D Printed Electrodes Modified by Prussian Blue Analogues
The water oxidation is the limiting step in the water-splitting process. Given this scenario, the development of new catalysts is essential in this field. The emergent demand is the use of Earth-abundant elements and catalysts with high performance under mild conditions. Because of this, catalysts such as Prussian Blue analogues (PBA) have been receiving a l

4. ENRIQUECIMENTO ELEMENTAR POR MEIO DE CULTIVO: PLANTAS E COGUMELOS
The foods enrichment with essential elements is an alternative to supply deficiencies of micronutrients and the fortification by rich cultivation is a promising strategy for the elemental enrichment of agricultural origin products, mainly in regions where there is high prevalence. On the other hand, in elemental enrichment procedures, possible antagonistic a

5. LA PARATRADUCTION DE L’IDENTITÉ DANS LES ESPACES DE TRADUCTION ET D’INTERPRÉTATION EN MILIEU SOCIAL (TIMS)
ABSTRACT When we address the issue of identity in TIMS spaces, we face an essential question. Indeed, the relationship with the other is evident in Health practices. What about these relationships, when the cultural diversity of our current societies redraws the patterns of identity established in previous models? In this paper we will deal with the question

6. PROCESSING OF A METAL CONCENTRATE FROM GROUND WASTE PRINTED CIRCUIT BOARDS IN ACIDIC MEDIA USING HYDROGEN PEROXIDE AS OXIDANT
The recovery of precious and base metals of a metal concentrate from ground waste printed circuit boards (PCBs) is described in detail. Samples were treated with NaOHaq. to remove the soldering mask. Experiments were performed in acidic medium (HF, H2SO4, CH3COOH or H3PO4) using H2O2 as oxidant. Base metals were leached in high yields (>99 wt.%) at ~40 ºC a

7. Quality pattern evaluation of frozen soursop pulps: an assessment based on chemical composition and chemometric analysis
Abstract In the present study, the physicochemical properties and mineral composition of commercially-frozen soursop pulps from the southern region of the state of Bahia, Brazil, were evaluated. The physicochemical parameters such as soluble solids (°Brix), acidity and pH were determined according to reference methodologies. For mineral composition evaluati

8. Minieditorial: Risco de FA após Ablação de Flutter Dependente de Istmo Cavo-Tricuspídeo: Vale a Pena Fazer a Ablação da FA Simultaneamente?
Considering the size of the Amazon region and the need for studies to establish soil trace metal concentrations in natural environments, the objective of this work was to evaluate heavy metal contents in a toposequence of an Amazon State microbasin. Soil samples were collected in three native forest topographic positions. Samples were opened for analysis by

10. Multi-Element Evaluation in Black Pepper (Piper nigrum L.) According to the Processing
Black pepper is one of the most consumed spices worldwide and the evaluation of trace elements content is essential to promote consumer safety. In this study, concentrations of the elements As, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Se, V and Zn was determined in samples of black peppercorn (n = 25) and ground black pepper (n = 25) to verify how processing affects

12. “The interviews were transcribed”, but how? Reflections on management research
Abstract Purpose In qualitative research, it is recurrent to conduct data collection through interviews, which must be first transcribed for the data to be analyzed. Although there is a relationship between the stages of the interview and the data analysis, the link between them (i.e. the transcription) seems to be a neglected methodological procedure. This
