3. 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

4. Rheological Parameters of Shear-Thickening Fluids Using an Experimental Design
Abstract: The influence of important factors related to fluid preparation on shear-thickening fluids (STF) is not well explored in literature. Thus, this paper aimed at analyzing the statistical significance of experimental conditions, such as fumed silica concentration (Cs), stirring time (tst), stirring speed (Sst) and sonication time (tso ), on the rheolo

5. Evaluation of the Acid Baking Technique to Decrease the Phosphorus Content of the Iron Ore
Unlike the available mineral resources, the steelmaking processes have demanded raw material with lower phosphorus content to decrease the costs, energy use, and the residue generated within the steel plant. One alternative is to develop pretreatment of the iron ore concentrates producing raw materials with lower phosphorus. Depending on the mineral structur

6. Corrosion Behavior of AA7075-T73 Aluminum Alloy During Machining of Aeronautical Components
Corrosion of AA7075-T73 aluminum alloy during machining process was studied. An experimental device was proposed in order to simulate machining procedure. A design of experiments - DOE was used in order to evaluate what process parameter is significant. Some electrochemical tests based on open-circuit potential vs time measurements and potentiodynamic polari

7. Analysis of quartz floatability using design of experiments
Abstract Quartz floatability in cationic reverse flotation depends on the suitable choice of surfactant type and the conditions under which they are applied. The design of experiments (DOE) allows the evaluation of process variables, in a structured and independent way, with statistical validation and a limited number of tests. Tests of microflotation of qua

8. 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

9. Análise da rugosidade superficial de barras de aço SAE 1045 após torneamento
RESUMO Neste trabalho foram investigadas as influências de alguns dos principais fatores do torneamento sobre o acabamento da superfície e a rugosidade de uma peça torneada. Foram analisadas barras de aço SAE 1045 torneadas em um torno controle numérico computadorizado (CNC), com auxílio da técnica de Planejamento de experimentos (DOE) para formar tri

10. Guerra de Xangô: ritual, perseguição e conflito na formação do campo religioso afro-sergipano
Resumo: O artigo procura investigar a formação do campo religioso afro-sergipano. Seu argumento central é de que, associados às práticas de “feitiçaria” e “bruxaria”, os adeptos das religiões afro-brasileiras eram por vezes envilecidos pela imprensa, perseguidos pelas forças de repressão e tratados como “fetichistas” pela Justiça.

11. Optimization of Atmospheric Pressure Photoionization for the Crude Oil Analysis Using Ultra-High Resolution Mass Spectrometry
Design of experiments (DOE) applied to mass spectrometry (MS), mainly focusing on the optimization of ionization techniques, has been applied to optimize experiments in order to provide the highest amount of information with the lowest number of experiments. However, DOE has not been used in petroleomics. For the first time, we applied DOE to optimize the ma

12. Physiological responses and animal behavior in Bonsmara-Hereford crosses vs. Hereford purebred on environment stress
ABSTRACT: Adaptative traits (rectal temperature-RT, respiratory rate-RR) and grazing behavior (Grazing, Ruminating and Rest time, and Sun or Shade time) of Bonsmara-Hereford crossbred-BH, n = 15, and purebred Hereford-HH, n = 18, yearling heifers, in a grazing system of Uruguay. Environment characterization was made using THIadjusted by radiation and wind sp
