1. METHODS FOR EXTRACTION AND ISOLATION OF AGATHISFLAVONE FROM POINCIANELLA PYRAMIDALIS
Agathisflavone is a natural biflavone with restricted occurrence in plants. This biflavone presents several biological activities and can be important to developing new drugs. Obtaining such a molecule on a large scale for in vivo tests is a challenge. To date, there are no reports regarding its synthesis; thus, it is important to improve and develop methods

2. Use of flash glucose-sensing technology in patients with type 2 diabetes treated with liraglutide combined with CSII: a pilot study
Glycemic variability (GV) may be linked to the development of diabetic complications by inducing inflammation, oxidative stress, and endothelial dysfunction. Flash glucose monitoring (FGM) provides a novel method of continuously monitoring interstitial glucose levels for up to 14 days. This study randomly assigned poorly controlled type 2 diabetes mellitus p

3. QUADRATURE ALGORITHMS FOR PHASE EQUILIBRIUM OF CONTINUOUS MIXTURES
Abstract Several methods for computing the Gauss-Christoffel quadrature used for the adaptive characterization of continuous mixtures were compared as to their efficiency and robustness. Two mixtures with molar fraction distribution given by truncated gamma distributions were used. We analyzed the Product-Difference, the Golub-Welsch, the Long Quotient-Modif

4. Effect of Welding Heat Input on the Microstructure and Mechanical Properties of Dissimilar Friction Stir-Welded Copper/Brass Lap Joint
Dissimilar lap welded joints of copper and brass metals were fabricated by friction stir welding (FSW) method at various welding heat inputs. The effect of welding heat inputs on the microstructure and mechanical properties of overlap welded joints at at two different join configurations (i.e. Advancing side and Retreating side joint configurations) was inve

5. Simulação do Processo de Soldagem Elétrica por Centelhamento de um Aço para Trilhos Ferroviários. Parte 1: Análise de Tensões Residuais Via Elementos Finitos
Resumo Trilhos longos, soldados pelo processo Flash Butt Welding (FBW), são a realidade das ferrovias brasileiras de média e alta carga por eixo. Embora apresentem características desejáveis do ponto de vista do comportamento dinâmico da via, as soldas são regiões de descontinuidade estrutural e mecânica onde se originam tensões residuais, e que est

6. Repeatability of the “flash-replenishment” method in contrast-enhanced ultrasound for the quantitative assessment of hepatic microvascular perfusion
This study aimed to evaluate the feasibility and repeatability of the flash-replenishment method in contrast-enhanced ultrasound (CEUS) perfusion imaging and assess quantitatively microvascular perfusion in the liver. Twenty healthy New Zealand rabbits were submitted to CEUS perfusion imaging with continuous intravenous infusion. Using flash-replenishment ki

7. Efficiency assessment of Flash Profiling and Ranking Descriptive Analysis: a comparative study with star fruit-powdered flavored drink
Abstract The objective of this study was to assess the efficiency of Flash Profiling (FP) and Ranking Descriptive Analysis (RDA) methods regarding sensory characterization using star fruit-flavored drink as matrix. Sample A was used as a standard. Other three samples were prepared based on sample A, by adding sugar, citric acid, carboxymethylcellulose or dye

8. Method to Determine the Electrical Energy for Ignition of Electro-Explosive Devices
ABSTRACT: During field trials, it was observed that the delay of ignition of electro-explosive devices (EED) depends on ratings of power supplies or dynamo and also on the firing cable lengths. The change in ignition delay of EEDs due to altered supplied current will detoriate the repeatability of sequence of actions in time-critical armament applications. I

9. Multi-model MPC with output feedback
In this work, a new formulation is presented for the model predictive control (MPC) of a process system that is represented by a finite set of models, each one corresponding to a different operating point. The general case is considered of systems with stable and integrating outputs in closed-loop with output feedback. For this purpose, the controller is bas

11. A simple method to evaluate, correlate and predict boiling and flash points of alkynes
Pontos de ebulição (T B) de alcinos acíclicos são preditos a partir de seus números de ponto de ebulição (Y BP) com a relação: T B(K) = -16,802Y BP2/3 + 337,377Y BP1/3 - 437,883. Os valores de Y BP, por sua vez, são calculados a partir da estrutura dos compostos utilizando a equação: Y BP = 1,726 + Ai + 2,779C + 1,716M3 + 1,564M + 4,204E3 + 3,905

12. Corrosion behavior of mild steel and SS 304L in presence of dissolved nickel under aerated and deaerated conditions
In dual purpose water/power co-generation plants, the presence of high concentration of Cu and Ni in the re-circulating brine/condensate as a result of condenser tubes corrosion has been attributed as one of the several causes of corrosion damage of flash chamber materials and water touched parts of the boilers. The present investigation deals with the effec
