1. Symptomatology associated with “Purple top”, an emerging disease of solanaceous fruit species
ABSTRACT “Purple top” is an emerging disease that affects solanaceous crops, reported mainly on Solanum tuberosum (potato). Additionally, Bactericera cockerelli has been reported as the insect vector of Candidatus Liberibacter solanacearum (CaLso), a pathogen that has been associated with this disease. However, the information about this disease in Andea

2. Micro-CT evaluation of apical enlargement of molar root canals using rotary or reciprocating heat-treated NiTi instruments
Abstract Objective The aim of this study was to evaluate the root canal preparation and apical enlargement of molar root canals with rotary or reciprocating heat-treated nickel-titanium (NiTi) instruments, by using micro-computed tomography (micro-CT). Methodology Mesial root canals (n=48) of mandibular molars, with a curvature between 20° and 40°, wer

3. Stress-Based Finite Element Methods for Dynamics Analysis of Euler-Bernoulli Beams with Various Boundary Conditions
Abstract In this research, two stress-based finite element methods including the curvature-based finite element method (CFE) and the curvature-derivative-based finite element method (CDFE) are developed for dynamics analysis of Euler-Bernoulli beams with different boundary conditions. In CFE, the curvature distribution of the Euler-Bernoulli beams is approxi

4. Sistemas de sensores ópticos baseados em fibra óptica de perfil-W dopada com Érbio / Optical sensing systems based on Erbium-doped W-fiber
Depressed-cladding (often referred to as dual-clad or "W"- fiber) fibers with fundamental-mode cutoffs provide high distributed losses at long wavelengths and low losses at short wavelengths. The magnitude of the abrupt transition between low-loss at short wavelengths and high-loss at long wavelengths exceeds 200 dB/km and is found to be extremely sensitive

5. Comparação entre mapas de solos obtidos pelos métodos convencional e digital numa área complexa / Comparison between soil maps obtained by conventional and digital methods in complex area
Soil maps are essential for the development of agricultural areas in an economically viable and environmentally friendly manner. So far, Brazil only has soil maps of small scale (1:250,000 to 1:1,000,000), whose use is limited to agricultural and environmental planning at the farm. Despite its importance, in Brazil a few mappings have been carried out by pub

6. Long-term follow-up of penile curvature correction utilizing autologous albugineal crural graft
PURPOSE: Peyronie's disease is an acquired connective tissue disorder of the penile tunica albuginea with fibrosis and inflammation. The disease produces palpable plaques, penile curvature and pain during erections. Usually it results in impairment of the quality of life. Our objective is to review the long-term results of the albugineal grafting harvested f

7. Hypersurfaces with prescribed mean curvature in Riemannian manifolds / HipersuperfÃcies com curvatura mÃdia prescrita em variedades riemannianas
This work shows results existence and uniqueness of graphs with prescribed mean curvature. We demonstrate that a natural fixation Dirichlet problem for graphs of average curvature is required to consider those graphs like leaves on a Riemannian submersion Killing transversal cylinder, the cylinder given by flow lines of a Killing vector field. Using this app

8. Assessing protein stability of the dimeric DNA-binding domain of E2 human papillomavirus 18 with molecular dynamics
The objective of this study is to understand the structural flexibility and curvature of the E2 protein of human papillomavirus type 18 using molecular dynamics (6 ns). E2 is required for viral DNA replication and its disruption could be an anti-viral strategy. E2 is a dimer, with each monomer folding into a stable open-faced β-sandwich. We calculated the m

9. The moving frame method through examples / O metodo do referencial movel via exemplos
The aim of this work is to present the Cartan s Moving Frame Method applied to curves, through several examples, starting with simple problems, going through publications of the 60´s, 70´s, and up to recent results. Although there are general theories for finding Cartan s moving frames, we chose to study a slightly more "handcraft" way of building the requ

10. Avaliação de modelos de regressão não linear na cinética de liberação de potássio de resíduos orgânicos / Evaluation nonlinear regression models on the potassuim kinetic release from organic residues
Potassium (K) is required in great amounts by crops, but its availability in Brazilian soils is less than its demand. Its supply can be efficiently made from organic sources when we know the pattern of release. Nonlinear models are appropriate in these situations since then estimate quantities of practical interest, and they have goodness of fit.

12. Métodos de amostragem e tamanho de amostra para avaliar o estado de maturação da uva Niágara Rosada / Sampling methods and sample size to evaluate the maturation state of the Ni´agara Rosada grape
Sao Paulo state is the main table grape producer in Brazil, being the Niágara Rosada (Vitis Labrusca) the predominant cultivar. To offer quality products to the market, the producers need to determine, periodically, the grapes maturation state, being the content of soluble solids the main variable measured. To determine this content, a sample of fruits in a
