1. Analytical method validation for the identification and quantification of dissolved gold and gold nanoparticles in cosmetics products by single particle inductively coupled plasma mass spectrometry
Nanoparticle (NP) applications have recently gained more space in the development of many products, especially in cosmetology. The aim of the present study was to validate a single particle inductively coupled plasma mass spectrometry technique for the detection and quantification of gold nanoparticles (AuNPs) and gold ions (Au (i)) in different cosmetics cu

2. Effects of Temperature and Concentration on the Determination of PET Viscosity
This work describes the use of experiment planning to investigate the effects of the variables temperature and concentration of the polymer solution on the viscosity test of polyethylene terephthalate (PET). For this, the response surface methodology was based on a central composite rotatable design (CCRD) to optimize the combinations of the analytical condi

3. Comparative study of inclusion removal from liquid steel in the RH and argon purging processes
Abstract In order to improve steel quality, it is necessary to increase the cleanliness of the liquid steel; that is, to reduce the number and size of the inclusions in the liquid steel, as well as to control their chemical composition. For this purpose, processes (with different operating costs) are used, such as the bubbling of inert gas in the steel ladle

4. Two Years Monitoring of Ethyl Carbamate in Sugar Cane Spirit from Brazilian Distilleries
This paper describes the monitoring of ethyl carbamate concentration in sugar cane spirit from industrial distilleries in Brazil. In total, 18 distilleries from Minas Gerais and São Paulo states were evaluated, with, a total of 336 samples from August 2017 to August 2019. The ethyl carbamate was analyzed using a previously validated mass spectrometric metho

7. Advances in the propagation of Brazilian Cherry tree
Resumo A Pitangueira é fruteira nativa da família Myrtaceae com ampla adaptação as diferentes condições edafoclimáticas do país, o que a torna muito conhecida. Todavia, ainda existem poucos pomares comerciais com a cultura, o que talvez seja em breve revertido uma vez que estudos vem demonstrando a importância do consumo de seu fruto para saúde hu

8. Effects of waterlogging stress on plant-pathogen interaction between Fusarium poae and wheat/ barley
ABSTRACT. Waterlogging stress is one of the abiotic factors which causes damage to crops affecting yield components and grain quality of wheat and barley. On the other hand, Fusarium poae is one of the most common Fusarium species isolated from wheat and barley. The aim of this study was to evaluate the effects of waterlogging and F. poae on disease paramete

10. Selection of materials for blast furnace injection using quality indicators
Abstract The injection of pulverized materials is a technique used in most of the blast furnaces in the world to reduce coke and charcoal consumption. In addition, injection is one of the main variables of the blast furnace heat control. Coal is the most used material for the injection, but some industries have been attempting to use other materials, usually
