13. Optimization and release evaluation for tea polyphenols and chitosan composite films with regulation of glycerol and Tween
Abstract In order to optimize the performance of chitosan-tea polyphenols composite films, effects of glycerol and Tween on the antioxidative activities and physical performance of chitosan composite films were evaluated. The results indicated that both flexibility and water vapour permeability of chitosan/tea polyphenols films were improved with the additio

14. EXPLOITING THE TIMETABLING FLEXIBILITY IN THE CONTEXT OF THE VEHICLE SCHEDULING PROBLEM WITH HETEROGENEOUS FLEET
ABSTRACT In the context of a heterogeneous fleet, the single-depot Vehicle Scheduling Problem is known as the Vehicle Type Scheduling Problem (VTSP). In this paper, we extend a VTSP model proposed in the literature to enable timetabling flexibility. Two strategies were developed to promote flexibility: aggregated trips and time windows. The former allows to

16. Effectiveness of the Pilates method for individuals with nonspecific low back pain: clinical and electromyographic aspects.
Abstract AIMS The aim of this study was to verify the influence of Pilates on muscle activation of lumbar multifidus (LM) and transversus abdominis/internal oblique muscles (TrA/IO) in individuals with nonspecific low back pain. METHODS Twelve individuals of both sexes with non-specific low back pain were evaluated before and after a two-month Pilates prog

17. Modeling and FPGA-based implementation of an efficient and simple envelope detector using a Hilbert Transform FIR filter for ultrasound imaging applications
Abstract Introduction Although the envelope detection is a widely used method in medical ultrasound (US) imaging to demodulate the amplitude of the received echo signal before any back-end processing, novel hardware-based approaches have been proposed for reducing its computational cost and complexity. In this paper, we present the modeling and FPGA impleme

18. An integrated optimization and simulation model for refinery planning including external loads and product evaluation
Abstract Because of its potential benefits, petroleum refineries are increasingly concerned about their planning operations. Although some refinery models for production planning were proposed, they are quite limited in their usefulness. This study describes an integrated approach involving nonlinear optimization and simulation of refinery units in order to

19. Pattern recognition of abscesses and brain tumors through MR spectroscopy: Comparison of experimental conditions and radiological findings
Abstract Introduction The interpretation of brain tumors and abscesses MR spectra is complex and subjective. In clinical practice, different experimental conditions such as field strength or echo time (TE) reveal different metabolite information. Our study aims to show in which scenarios magnetic resonance spectroscopy can differentiate among brain tumors,

20. Productive performance and economic evaluation of tilapia stocked in different times of the year
ABSTRACT This study aimed to determine production cycles based on the stocking period and the influence of the cycles on productive performance indices, production costs, and profitability. The present study was carried out on a fish farm located in Palmital - SP, Brazil, which consists of 2706 m3 of net cages with an annual production of 400 tons of tilapia

21. Optimum Design of Effective Parameters for Orthotropic Plates with Polygonal Cut-Out
Abstract This paper investigates the effect of different parameters on stress analysis of infinite orthotropic plates with central polygonal cutout using gray wolf optimization algorithm. The important features of gray wolf algorithm include flexibility, simplicity, short solution time and ability to avoid local optimums. The effective parameters on stress d

22. Elaboration and acceptability of restructured hams added with jabuticaba skin
Abstract Jabuticaba skin flour (JSF), rich in antioxidants and fibre, was used in order to develop four restructured hams in different combinations with meat: 0% control – without the addition of JSF, with the addition of 0.5% JSF, 1.0% JSF and 1.5% JSF, meeting, therefore, the growing demand for meat products with functional appeal. Physicochemical charac

23. Waterborne hyperbranched alkyd-acrylic resin obtained by miniemulsion polymerization
Abstract Four waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by using benzoyl peroxide (BPO) and ammonium persulfate (AP) as initiators. The reaction between HBR and acrylic monomers was evidence

24. The effect of different training modalities on physical fitness in women over 50 years of age
Abstract It is not yet clear which physical exercise protocols have greater potential to mitigate the functional decline in physical fitness (coordination, flexibility, strength, agility and cardiorespiratory capacity). Thus, the objective of this study was to compare different training modalities on physical fitness in women over 50 years of age and underst
