1. IDENTIFICAÇÃO DE ADULTERANTES DE BIODIESEL METÍLICO DE CRAMBE EM MISTURAS COM DIESEL, USANDO FT-MIR E CARTAS DE CONTROLE MULTIVARIADAS BASEADAS NO SINAL ANALÍTICO LÍQUIDO
Adulterants in biodiesel/diesel blends modifies its physical and chemical properties. In this work, Fourier Transform Mid-Infrared spectrometry (FT-MIR) and multivariate control charts based on Net Analyte Signal (NAS) were used to monitor the quality of Crambe methyl biodiesel in relation to the biodiesel content and the presence of adulterants. The calibra

2. Is there a difference between presence of single stone and multiple stones in flexible ureterorenoscopy and laser lithotripsy for renal stone burden <300mm2?
ABSTRACT In this study, we aim to evaluate and compare the effectiveness of flexible ureterorenoscopy (f-URS) for solitary and multiple renal stones with <300 mm2 stone burden. Patients' charts who treated with f-URS for kidney stone between January 2010 and June 2015 were reviewed, retrospectively. Patients with solitary kidney stones (n:111) were enrolled

3. EFICIÊNCIA DOS GRÁFICOS DE CONTROLE NA DETECÇÃO DE OUTLIERS EM PROCESSOS AUTORREGRESSIVOS E DE MÉDIAS MÓVEIS / EFFICIENCY OF CONTROL CHARTS TO DETECT OUTLIERS IN AUTOREGRESSIVE AND MOVING AVERAGE PROCESS
This research approaches the prediction models application along with the usage of residual control charts to evaluate productive processes with characteristics of autocorrelation in its samples. The overall objective was to determine the Individual Measurement Control Charts (IMCC) and the Exponentially Weighted Moving Average (EWMA) efficiency when applied

4. Aplicação de quimioterapia e espectroscopia no infravermelho no controle de qualidade de biodiesel e mistura biodiesel/diesel / Application of chemometrics and infrared spectroscopy in the quality control of biodiesel and biodiesel blend
Multivariate control charts in jointly with near infrared spectroscopy were developed to verify the quality of biodiesel blends (2% of biodiesel and 98% of diesel). The control charts were built using the net analyte signal, generating three charts: the NAS chart that corresponds to the analyte of interest (biodiesel in this case), the interference chart tha

5. Utilização do sinal analitico liquido para avaliação de modelos de calibração multivariada atraves do calculo de figuras de merito e de cartas de controle / Utilization of net analyte signal for validation of models of multivariate calibration by using figure of merit and chart control
This study was mainly intended to elaborate the validation of multivariate calibration models based on the determination of figures of merit and multivariate control charts constructed with data from Nimesulide tablets upon near-infrared spectroscopy use. A total of 69 synthetic samples were prepared containing the active principle (Nimesulide) in the range
