2. Application of quality by design approach in RP-HPLC method development for simultaneous estimation of saxagliptin and dapagliflozin in tablet dosage form
A simple, sensitive, precise, accurate and robust high performance liquid chromatographic method has been developed for simultaneous estimation of saxagliptin (SAXA) and dapagliflozin (DAPA) in pharmaceutical formulation. Design of experiments (DoE) was applied for multivariate optimization of the experimental conditions of RP-HPLC method. Risk assessment wa

3. Monitoramento de Longo Prazo e Climatologia de Campos Estratosféricos quando da Ocorrência dos Eventos de Influência do Buraco de Ozônio Antártico sobre o Sul do Brasil
Resumo O monitoramento de longo prazo dos eventos de Influência do Buraco de Ozônio Antártico sobre o Sul do Brasil foi realizado no período de 35 anos entre 1979 e 2013 e calculada a climatologia e anomalias dos campos estratosféricos quando de sua ocorrência. Para isso, foram analisados os dados da coluna total de ozônio (CTO) obtidos através de Es

4. Investigation on the Effects of Process Parameters on Laser Percussion Drilling Using Finite Element Methodology; Statistical Modelling and Optimization
Abstract In the present research, the simulation of the Nickel-base superalloy Inconel 718 fiber-laser drilling process with the thickness of 1mm is investigated through the Finite Element Method. In order to specify the appropriate Gaussian distribution of laser beam, the results of an experimental research on glass laser drilling were simulated using three

5. Recycling assessment of multilayer flexible packaging films using design of experiments
AbstractThe viability of recycling post-industrial packaging waste, compounded from multilayer laminated PET-PE films, for production of polymer blends with good physico-mechanical performance is analyzed. Initially, several PET-PE model-blends were prepared from fresh polymers and were compounded with different formulations, based on design of experiments (

6. A DOE based approach for the design of RBF artificial neural networks applied to prediction of surface roughness in AISI 52100 hardened steel turning
The use of artificial neural networks for prediction in hard turning has received considerable attention in literature. An often quoted drawback of ANNs is the lack of a systematic way for the design of high performance networks. This study presents a DOE based approach for the design of ANNs of Radial Basis Function (RBF) architecture applied to surface rou

7. Avaliação da influência dos parâmetros do processo de soldagem TIG sobre a qualidade de uma peça fabricada em aço elétrico silicioso / Influence of TIG welding process parameters on the quality of a piece fabricated with silicon electrical steel
The TIG welding process (Tungsten Inert Gas), also known as GTAW (Gas Tungsten ArcWelding), is the most commonly used process for welding of thin plates where there is a need for an excellent control of the temperature applied on the piece. This paper presents a study carried out in partnership between the Department of Graduate Studies in Scienceand Materia

8. Impacto da assimilação de dados de precipitação no sistema RPSAS/CPTEC: um estudo de caso de complexo convectivo de mesoescala / Impact of precipitation assimilation in CPTEC s RPSAS system: a case study of mesoscale convective system
This work presents the results of a impact study of estimated precipitation data assimilation in RPSAS from CPTEC, during January 2003. In this study, the precipitation assimilation was performed during the generation of first guess by the regional Eta model using a methodology similar to nudging. From this first guess, the RPSAS system generates an analysis
