1. Grazing management under integrated crop-livestock system on physical soil attributes and grain yield soybean
ABSTRACT Integrated crop-livestock system (ICLS) can help improve the soil physical attributes, increasing the nutrients cycling and yield potential. We evaluated the effect of forage height management under ICLS on physical soil attributes and water infiltration. Field experiment was carried out for two consecutive years in a randomized complete block desig

2. Evaluation of Ventricular Remodeling and Prognosis in Patients with Aortic Stenosis Who Underwent Surgical or Percutaneous Transcatheter Aortic Valve Replacement
ABSTRACT Introduction: Aortic stenosis is the most common heart valve disease in the world, and patients that present with symptoms have a high mortality rate. Aortic valve replacement has the objective of promote left ventricular remodeling, reduce symptoms, and increase overall survival. The objective of this study is to evaluate reverse remodeling of the

3. Aquamarine from Massangana batholith, Rondônia State: mineral chemistry and fluid inclusion data
Abstract Beryl is usually found in granite-pegmatite systems. The addition of chromophore elements (V, Cr, Mn, Fe) into the crystalline structure favors color changes in beryl and thus generates some of the world’s expensive gems such as emerald, morganite, heliodor and aquamarine. The Massangana polyphasic batholith is a well-known cassiterite, wolframite

5. Estruturas invisíveis de segregação na Região Metropolitana de Goiânia
Resumo Este artigo visa investigar a estrutura invisível de segregação da Região Metropolitana de Goiânia (RMG), a partir das inter-relações entre processos de produção do espaço urbano, princípios de planejamento e dinâmicas populacionais. Essas inter-relações são fundamentais para compreender a estruturação de desigualdades socioeconômica

6. Autofluorescência em um caso de distrofia macular anular concêntrica benigna
Resumo A distrofia macular anular concêntrica benigna (DMACB) é uma patologia retiniana rara e provavelmente subdiagnosticada em nosso meio, que se caracteriza por um defeito retiniano em bull’s eye sem uso prévio de antimaláricos, associado à preservação relativa da acuidade visual. Devido à escassez de publicações sobre o tema, existem poucos d

9. Mapping of equipotential surfaces using the free Quantum Geographic Information System software
Abstract In this work, we report the mapping of electrical equipotential lines (1D) and equipotential surfaces (3D) using the free Quantum Geographic information system (QGIS) software. For this purpose, experiments taking into account, four different electrical configurations were performed on physics classes of undergraduate students, using two conductors

10. Is hepatojugular reflux a good predictor of heart failure with preserved ejection fraction?
RESUMO A hipertensão pode cursar com disfunção diastólica de ventrículo esquerdo (VE) e a consequência disso pode ser sintomas e sinais de insuficiência cárdica (IC). O refluxo hepatojugular (RHJ), descrito como sinal de regurgitação da valva tricúspide, pode refletir alterações estruturais e funcionais do VE no paciente hipertenso. O sinal pode
