1. Quimiometria III - Revisitando a análise exploratória dos dados multivariados
In this work, three methods for pattern recognition, used as exploratory data analysis, are revisited. A brief review of principal component analysis, PCA, an unsupervised method, is provided. Next, the Mahalanobis distance and the confidence ellipses usually drawn around the scores samples are discussed. Fisher’s canonical variate analysis (a supervised m

3. Development and Validation of a Rapid and Reliable HPLC-FLD Method for the Quantification of Ciprofloxacin and Enrofloxacin Residues in Zea mays
The accumulation of antibiotics by plants is a currently concern associated to yield reduction and transference of antibiotic residues along the food web. Maize is a staple food in many parts of the world; it is also considered an important ingredient in animal nutrition. Considering the lack of validated analytical methods for the analysis of ciprofloxacin

4. Validation and Application of a Methodology for Quantifying Levels of Parabens in Sports Supplements from Brazil Using Liquid Chromatography-Mass Spectrometry
Although parabens have been reported to be used as antimicrobial preservatives in personal care products, pharmaceuticals, and foodstuffs, little is known about the occurrence of these compounds in sports supplements. In this study, a simple, fast and sensitive liquid chromatography tandem mass spectrometry method for simultaneous determination of five commo

5. Hemodynamic outcome of different ventilation modes in laparoscopic surgery with exaggerated trendelenburg: a randomised controlled trial
Abstract Purpose: To compare hemodynamic effects of two different modes of ventilation (volumecontrolled and pressure-controlled volume guaranteed) in patients undergoing laparoscopic gynecology surgeries with exaggerated Trendelenburg position. Methods: Thirty patients undergoing laparoscopic gynecology operations were ventilated using either volume-contr

6. Effects of Citrus Sudden Death Disease on Fatty Acid Profile of Orange Tree Bark
Citrus sudden death (CSD) is a disease that has affected millions of orange trees in Brazil, leading to economic losses in the order of billions of US dollars. This article examines the effects of CSD on the fatty acid composition of triacylglycerides (TAG) extracted from rootstock and scion bark. The fatty acid profile determined by gas chromatography showe

7. The Effect of Turbinate Injection of Botulinum Toxin A on the Symptoms of Idiopathic Rhinitis
Abstract Introduction Idiopathic rhinitis is a nonallergic and noninfectious rhinitis characterized mainly by nasal obstruction and rhinorrhea, resulting from an autonomic imbalance. Botulinum toxin type A (BTX-A) demonstrated its action in reducing rhinorrhea and nasal obstruction when injected into the nasal turbinates or septum. Objective To analyze the

8. A Numerical Study of Linear Long Water Waves over Variable Topographies using a Conformal Mapping
ABSTRACT In this work we present a numerical study of surface water waves over variable topographies for the linear Euler equations based on a conformal mapping and Fourier transform. We show that in the shallow-water limit the Jacobian of the conformal mapping brings all the topographic effects from the bottom to the free surface. Implementation of the nume

10. Environmental effects of leachate extracts from reclaimed asphalt pavement: determination of metals, polycyclic aromatic hydrocarbon and acute toxicity to Daphnia magna
RESUMO Reclaimed Asphalt Pavement (RAP) has a variety of organic and inorganic compounds that can interact with the environment and promote deleterious effects on human health. This study investigated the potential toxicity of RAP through metal determination, polycyclic aromatic hydrocarbon (PAH) analysis and acute toxicity tests with Daphnia magna. Leached

11. Pretreatment and Enzymatic Saccharification of Water Hyacinth, Sugarcane Bagasse, Maize Straw, and Green Coconut Shell Using an Organosolv Method with Glycerol and FeCl3
A method to pretreatment of biomasses using glycerol as a green solvent was developed. Optimization of organosolv pretreatment was performed using a 23 factorial design, investigating synergism among the variables particle size (from < 0.85 to > 2.0 mm), FeCl3 concentration (0.025-0.175 mol L-1), and temperature (160-220 °C). Although the effects of the var

12. Diagnostic accuracy of lung ultrasound for transient tachypnea: a meta-analysis
Abstract Objective: The objective of this meta-analysis was to study the diagnostic value of lung ultrasound (LUS) for transient tachypnea of the newborn (TTN). Methods: Embase, Cochrane Library, PubMed, Web of Science, and Google Scholar were searched, and the last search date was October 31, 2020. Studies on the diagnostic accuracy of pulmonary ultrasoun
