1. Topdressing nitrogen fertilization associated with trinexapac-ethyl on industrial quality of oat grains
ABSTRACT Nitrogen fertilization, besides increasing productivity, can favor the production of well-formed, large, and heavy grains, which are traits valued by the oat processing industry. However, high nitrogen (N) doses may lead to plant lodging, which could be solved by using growth retardant. This study aimed to evaluate the industrial quality of white oa

3. Uso de técnicas electroquímicas para determinar la resistencia a la corrosión localizada de un acero inoxidable súper dúplex UNS S-32760
ABSTRACT Super duplex stainless steel UNS S-32760 is one of the most commonly used alloys in several industrial applications, due to its high corrosion resistance. However, this characteristic is affected when the alloy is exposed to aggressive environments. In this work, the effect of temperature on the critical potential of super duplex stainless steel was

5. Tolerance of crambe (Crambe abyssinica Hochst) to salinity and water stress during seed germination and initial seedling growth
RESUMO Crambe é uma oleaginosa adequada para vários fins industriais, como a produção de biodiesel, plásticos, borrachas e cosméticos. Há relatos da rusticidade desta espécie e seu potencial para o plantio em ambientes áridos e semi-áridos, onde a escassez de água e salinidade do solo são comuns. Entretanto, estudos sobre a tolerância de semente

6. Brazilian Bioluminescent Beetles: Reflections on Catching Glimpses of Light in the Atlantic Forest and Cerrado
ABSTRACT Bioluminescence - visible and cold light emission by living organisms - is a worldwide phenomenon, reported in terrestrial and marine environments since ancient times. Light emission from microorganisms, fungi, plants and animals may have arisen as an evolutionary response against oxygen toxicity and was appropriated for sexual attraction, predation

7. SOLUBILIDADE E REATIVIDADE DE GASES
This paper deals with the solubility and reactivity of gases, especially in water, covering the main aspects that influence the dissolution process, namely polarizability of atoms or molecules in gas phase and their ability to react with the solvent. The discussion highlights the importance of solubility of gases in several biological processes, such as resp

8. Oxidative stress and antioxidant response in a thermotolerant yeast
Abstract Stress tolerance is a key attribute that must be considered when using yeast cells for industrial applications. High temperature is one factor that can cause stress in yeast. High environmental temperature in particular may exert a natural selection pressure to evolve yeasts into thermotolerant strains. In the present study, three yeasts (Saccharomy

9. Influence of Ferrite Phase Content on the Electrochemical Properties of Duplex Stainless Steels
Duplex stainless steels have a large number of industrial applications and may replace high cost materials, especially in chloride-containing environments like seawater in off-shore platforms due to their high mechanical properties and good corrosion resistance. The influence of the ferrite content on the performance of duplex stainless steels in these corro

10. REALIGNED MODEL PREDICTIVE CONTROL OF A PROPYLENE DISTILLATION COLUMN
Abstract In the process industry, advanced controllers usually aim at an economic objective, which usually requires closed-loop stability and constraints satisfaction. In this paper, the application of a MPC in the optimization structure of an industrial Propylene/Propane (PP) splitter is tested with a controller based on a state space model, which is suitab

11. Phytoremediation potential of aquatic herbs from steel foundry effluent
Discharge of industrial effluents in aquatic environments is a serious threat to life due to toxic heavy metals. Plants can be used as cheap phytoremedients in comparison to conventional technologies. The present study was conducted to check the phytoremediation capability of two free-floating plants, i.e., Pistia stratiotes and Eichhornia crassipes, for the

12. Corrosion resistance of 2024 aluminum alloy coated with plasma deposited a-C:H:Si:O films
AA 2024 aluminum alloy is widely employed in aeronautic and automobilist industries. Its hardness and low density are attractive properties for such industrial areas. However, since it contains copper, it undergoes severe corrosion in aggressive media as saline or low Earth orbit environments. In this work, it was investigated the properties of films deposit
