1. REHYDRATION KINETICS OF DEHYDRATED BERRIES
ABSTRACT Cranberries and blueberries are small fruits known for their antioxidant properties. However, due to their high water content and short shelf life, they are generally marketed as dehydrated berries. The present work aimed to model the rehydration of dehydrated berries. Rehydration tests were conducted at 7 and 29°C using milk as a solvent and at 7,

2. In silico Evaluation of Cucurbit[6]uril as a Potential Detector for Cocaine and Its Adulterants Lidocaine, Caffeine, and Procaine
Illicit drugs and their trafficking require worldwide efforts in investigation, detection, and control. Colorimetric tests are often applied to identify drugs. Cocaine has some well-known adulterants that can provide a false positive response. Cucurbit[6]uril (CB[6]) has been suggested as a potential detector for cocaine and other illicit drugs. This work us

3. Duas décadas de premiação, quantas de inovação? O papel da difusão no Prêmio Enap
Resumo Este estudo mapeia dimensões e variáveis explicativas da difusão da inovação em serviços públicos e testa sua aplicação ao caso do Prêmio Enap. Por meio de revisão de literatura, compõe-se um modelo teórico conceitual explicativo da difusão da inovação aplicável a serviços públicos para posterior teste empírico. Esse modelo tem 10

4. Austenitic Grain Size Prediction in Hot Forging of a 20MnCr5 Steel by Numerical Simulation Using the JMAK Model for Industrial Applications
Yield strength and toughness in steels are directly associated with hot forging processes, especially by controlling austenitic grain size and cooling conditions. The phenomenological JMAK model in macroscale has been applied in different material classes to predict grain size after hot forming. However, on an industrial application, there is still a lack of

5. Family interactions and the involvement of adolescents in bullying situations from a bioecological perspective
Resumo A exposição ao bullying escolar é uma realidade para crianças e adolescentes, porém ainda não foram exploradas suficientemente algumas complexidades do fenômeno. Assim, este estudo objetivou sintetizar em um modelo teórico evidências empíricas sobre a relação entre bullying e variáveis familiares. Com delineamento misto, a amostra total f

7. Actual evapotranspiration and crop coefficient of sweet orange during the initial development phase in the Rio Largo region, Alagoas
RESUMO: A determinação da evapotranspiração real da cultura (ETa) é importante para o manejo da irrigação. Os principais métodos e modelos físicos de estimativa da ETa requerem dados que não são facilmente disponíveis. Neste trabalho, obteve-se o coeficiente da cultura (Kc) da laranja lima na fase inicial de desenvolvimento e avaliou-se o desemp

8. Evaluación de caminos de difusión de Al en UAl4
ABSTRACT Once the stable structure of point defects and concentrations of defects in thermal equilibrium were obtained for each composition of Al of the compound UAl4, we identified, in this work, the more likely mechanisms for Al mobility in UAl4, and we analyzed transition states in the diffusion of Al in UAl4 by the Nudged Elastic Band (NEB) method implem

9. Modelamiento de la respiración del mango (Mangifera indica l.) usando el método de sistema cerrado a diferentes temperaturas
Abstract Measuring the respiration rate of fresh products is essential to design correct of packaging systems. For such effect, rates of consumption of O2 and production of CO2, usually are taken are initial data of system comportment. The aim of this work, was modelling the respiration of whole mango (Mangifera indica L.), variety Tommy Atkins using a clos

10. Photoluminescence of Solvent-Selected Fluorescent Moieties in MEH-PPV Solutions and Films
In this work, we examined how photoluminescence in poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) is affected by morphology, dictated by the mode of preparation. For that, MEH-PPV dilute solutions in good and non-solvents, thick cast films with poly[methylmethacrylate] (PMMA) as inert matrix and spin-coated thin films were prepared. Thes

11. Solubility of 1-Adamantanamine hydrochloride in Six Pure Solvents between 283.15 K and 333.15 K
Abstract The solubility of 1-adamantanamine hydrochloride (1-AH) in ethanol, acetic acid, distilled water, N -methylpyrrolidone (NMP), N,N -dimethylformamide (DMF) and dimethylacetamide (DMAC) between 283.15 K and 333.15 K was measured using a laser monitoring observation technique. Results of these measurements were correlated with the NRTL equation and a s
