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. SEWAGE PERFORMANCE OF A NEW TYPE OF FLAP FILTER
ABSTRACT The drainage performance of a mesh filter determines the water consumption degree of the filter and the efficiency of the next work cycle. Through analysis, we found that the influent flow rate and the sediment content of the influent were important influencing factors. This experiment focused on the drainage time, pressure difference, and cleanline

3. INCREASED ENERGY COGENERATION IN THE SUGAR-ENERGY SECTOR WITH THE USE OF SUGARCANE STRAW, ELECTRIFICATION OF DRIVES, AND HIGH-DRAINAGE ROLLERS IN THE EXTRACTION
ABSTRACT The sugar-energy sector stands out in the production of electrical energy in the Brazilian energy matrix. The updating of Law 9,427 allowed increasing the limit of power injected in the transmission or distribution systems of existing projects from 30 to 50 MW, encouraging studies of expansion and/or implementation of new cogeneration projects. This

4. Uma proposta experimental para o estudo de oscilações acopladas usando um simulador de propagação de ondas mecânicas em meios sólidos
Resumo Neste artigo, apresentamos inicialmente um aparato, construído com materiais de fácil acesso, que pode ser empregado no estudo da lei de Hooke utilizando-se anéis de garrafa PET. Nesta fase da experimentação, esperamos que o professor reconheça junto aos seus estudantes que um anel mais largo possui constante elástica maior do que outro mais es

5. Terrorismo Internacional e Armas de Destruição em Massa: relativizando a liberdade de navegação, a soberania e o direito de visita em alto-mar
Resumo Este trabalho analisa a normatividade internacional produzida para a fiscalização do transporte de armas de destruição em massa pelo mar. A partir da inflação normativa e do surgimento de novos atores preocupados com o assunto, questiona-se: em que medida o terrorismo forçou a reconfiguração dos princípios regentes da navegação em alto-mar

6. Mass Variation Rate, in Acidic Environment, of Polyhydroxybutyrate and Chitosan matrices with Potential Application as Controlled Drug Delivery System
Polymers such as the biocompatible polyhydroxybutyrate (PHB) and the polysaccharide chitosan (Chi), a pH-sensitive polymer, have been studied for drug delivery applications and scaffolds production. In this work, matrices of PHB and Chi were produced by compression molding (SPHB-Chi) and loaded with a broad-spectrum biocide chlorhexidine (CHX) (SPHB-Chi-CHX)

7. OBRIGATORIEDADE ESCOLAR E INVESTIMENTO NA EDUCAÇÃO PÚBLICA: UMA PERSPECTIVA HISTÓRICA (SÃO PAULO, 1874-1908)
RESUMO O objetivo do artigo é discutir como São Paulo foi se organizando administrativa e financeiramente para assumir a responsabilidade pela criação e expansão da escola pública, moderna, obrigatória e de massas, a partir da primeira lei paulista de obrigatoriedade escolar, a Lei n. 9 de 22 de março de 1874. A delimitação temporal final é 1908,

8. Propagation of vibrational modes in classical harmonic lattice with correlated disorder
Abstract: The vibrational modes with nonzero frequency are localized in harmonic lattice with disordered masses. In our work, we investigated numerically the propagation of vibrational energy in harmonic lattice with long-range correlated disordered masses, which are randomly distributed with power law spectrum S ( k ) ∝ k − α. For α = 0, a standar

9. Factors and mass ratio analyses for Reactive Blue 19 dye decolorization using ozone: an experimental and analytical modelling approach
RESUMO Os corantes reduzem significativamente a penetração da luz solar no corpo d’água e, consequentemente, afetam a fotossíntese e a transferência de oxigênio. Realizaram-se modelagens experimental e analítica da remoção do azul reativo 19 por ozônio. Para isso, avaliaram-se os atributos e a taxa mássica por ensaios em batelada. A eficiência

10. Simultaneous determination of five N-alkylamides in the root of Anacyclus pyrethrum by HPLC and profiling of components in its methanolic root extract by UPLC/Q-TOF-MS
ABSTRACT The root of Anacyclus pyrethrum (L.) Lag., Asteraceae, is very widely used for treating various diseases in Traditional Uygur Medicine, particularly in the treatment of vitiligo. However, there have been few studies on the quality standards of A. pyrethrum in China. A. pyrethrum contains abundant N-alkylamides, which are considered to be the princip

11. CHEMOMETRIC TOOLS AND FTIR-ATR SPECTROSCOPY APPLIED IN MILK ADULTERATED WITH CHEESE WHEY
Brazilian law forbids the addition of cheese whey in milk. However, adulteration with cheese whey is one of the most applied fraud due to its low cost. The detection of this fraud is the quantification of Caseinomacropeptide (CMP). The CMP is a constituent of the whey that can be used as adulteration marker. Thus, an analytical method capable of identifying

12. Use of stable isotopes of carbon to detect coconut water adulteration
ABSTRACT: Industrialized coconut water may have been adulterated by adding sugar above the limit permitted by law. According to Brazilian law, industrialized coconut water can receive the maximum addition of 1 g of sugar per 100 mL of the drink. This work aimed to detect adulteration in industrialized coconut water produced in Brazil and measure the relative
