Determination of sorbate and benzoate in beverage samples by capillary electrophoresis - Optimization of the method with inspection of ionic mobilities
(ELSEVIER SCIENCE BV, 2008)
The aim of this study was to develop a fast capillary electrophoresis method for the determination of benzoate and sorbate ions in commercial beverages. In the method development the pH and constituents of the background ...
Development of a fast capillary electrophoresis method for the determination of propranolol-Total analysis time reduction strategies
(ELSEVIER SCIENCE BV, 2009)
The aim of this study was to develop a fast capillary electrophoresis method for the determination of propranolol in pharmaceutical preparations. In the method development the pH and constituents of the background electrolyte ...
Vision-based heading angle estimation for an autonomous mobile robots navigation
(07/01/2014)
Autonomous mobile robots navigation and control systems are still hugely important in real time robotic applications. When moving towards fully autonomous navigation, guidance plays a vital task for successful autonomous ...
Modeling of Cooling Curves in Zn-Al Diluted Alloys
(IJEIT, 2013-11)
In this paper we analyze the effect of size and the movement of a zone of coexistence of two phases which release latent heat during solidification on the cooling curves of pure Zn and Zn-1wt.%Al; Zn-2wt.%Al; Zn-3.wt%Al; ...
Comparison of panoramic stereoscopic sensors based on hyperboloidal mirrors
(IEEE, 2009)
Panoramic distance maps can provide valuable information for mobile robot navigation. An approach to obtain such distance maps is to implement a stereoscopic system using two hyperboloidal catadioptric sensors. This paper ...
Regulação coordenada da mobilização de lipídios e proteínas por hormônios, fontes de carbono e nitrogênio durante o crescimento pós-germinativo em Girassol
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em BioquímicaBioquímica; Biologia Molecular, 2012-10-17)
The mobilization of food reserves in storage tissues and allocation of their
hydrolysis products in the growing axis are critical processes for the establishment of
seedlings after germination. Therefore, it is crucial ...
Smooth global and local path planning for mobile robot using particle swarm optimization, radial basis functions, splines and Bézier curves
(2014)
An approach to plan smooth paths for mobile robots using a Radial Basis Function (RBF) neural network trained with Particle Swarm Optimization (PSO) was presented in [1]. Taking the previous approach as an starting point, ...
A novel approach based on capillary electrophoresis coupled to augmented multivariate curve resolution-alternating least-squares modeling for the determination of pKa of 2-hydroxy-4,6-dimethylpyrimidine in nicarbazin
(Elsevier Science, 2016-01)
The determination of the dissociation constant of 2-hydroxy-4,6-dimethylpyrimidine in nicarbazin was carried out by means of capillary electrophoresis using a dynamic coating of a fused-silica capillary with high-molecular-mass ...
Growth Rate and Acceleration Analysis of the COVID-19 Pandemic Reveals the Effect of Public Health Measures in Real Time
(2020-05-22)
Background: Ending the COVID-19 pandemic is arguably one of the most prominent challenges in recent human history. Following closely the growth dynamics of the disease is one of the pillars toward achieving that goal. ...
Monitoramento de múltiplos perímetros dinâmicos com robôs móveis
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE CIÊNCIA DA COMPUTAÇÃOPrograma de Pós-Graduação em Ciência da ComputaçãoUFMG, 2020-03-30)
The usage of mobile robots to perform tasks that were previously done only by station- ary objects or humans has been one of the main focus of studies nowadays. Activities such as patrolling, surveillance, rescuing, tracking, ...
