Natural fiber composites with polymeric matrix has been the focus of studies by having good mechanical properties and low weight, which allows its use in various environments, including hospital, radiotherapy and radiology rooms. Its major difficulty is the lack of affinity of the component materials, causing detachment of the interface and lower load transfer between matrix and reinforcement. An alternative may be composites based on natural fibers and polyurethane derived from castor oil. The incidence of radiation can lead to degradation of polymeric material and change its mechanical properties. The objective of this study was to obtain and characterize composites of dispersed sisal fibers and sisal fabric with polyurethane matrix based on castor oil without addition of compatibilizing agents, which may be used in environments that receive radiation at high intensity. The composites were obtained by cold pressing, irradiated with gamma radiation, dose of 25 kGy, and evaluated before and after irradiation with thermal, infrared, surface and mechanical testing. It was observed that there may be chemical affinity between the reinforcing material and the matrix, since was not observed detachment from the fiber / polymer interface. The materials can be considered hydrophilic by contact angle analysis. Maximum values of bending stress of 80.33 MPa and elastic modulus in bending of 4.40 GPa for the sisal fabric / polyurethane composite without irradiation were obtained...

Many industrial processes like crude oil transportation in pipelines operate on two-phase flow regime, especially in slug flow pattern. Slug flows are characterized by the intermittent succession of liquid slugs having a large momentum, followed by long bubbles of compressible gas. This kind of flow has been a topic of research over the last decades; however, few mathematical models for this complex flow can be found in the literature. Among those, one might mention the Eulerian two-fluid and drift flux, and the Lagrangian slug-tracking. Based on the work of Renault (2007), this work presents a Lagrangian methodology to capture the process of slug initiation for horizontal and near horizontal pipes. Starting from one dimensional two-fluid model, the equations of momentum and mass conservation were simplified. The motion generated by the dynamic pressure of the gas was decoupled from the slow movement of the liquid film. The resulting system of equations for the gas phase was discretized using the finite difference method and solved with the tri-diagonal matrix algorithm (TDMA). The liquid motion in the bubbles was then modeled by a modified version of shallow water equations. A software using Intel Visual Fortran language to simulate the process of slug initiation in a gas-liquid stratified flow was developed. Wave growth in the liquid-gas interface was numerically monitored until one of those waves reached the top of the pipe to form a slug. Numerical simulations were performed for different gas-liquid flow conditions...

This study presents a methodology, based on the Galerkin method, to quantify the uncertainty in the stochastic bending problem of an Euler-Bernoulli beam resting on a Pasternak foundation. The uncertainty in the stiffness coefficients of the beam and foundation is represented by parametrized stochastic processes. The probability limitation on the random parameters and the choice of an appropriated approximate solution space, necessary for the subsequent demonstration of uniqueness and existence of the problem, are considered by means of theoretical hypothesis. The finite dimensional space of approximate solutions is built by tensor product between spaces (deterministic and randomic), obtaining a dense space in the theoretical solution space. The Wiener-Askey scheme of generalizes chaos polynomials is used to represent the stochastic process of the beam deflection. The stochastic finite element method is presented and employed in the numerical solution of selected examples. The results, in terms of statistical moments, are compared to results obtained through Monte Carlo simulations.; Este trabalho apresenta uma metodologia, baseada no método de Galerkin, para quantificar a incerteza no problema de flexão estocástica da viga de Euler-Bernoulli repousando em fundação de Pasternak.

The aim of this paper is to describe the use of the Flexibility Method to solve two classical problems pertained by structural analysis knowledge area, in engineering context: the matrix analysis of framed structures. Two beams statically indeterminated are solved. There are three specific motivations to make a presentation of a complete solution for those problems, by this method. The first one is its pedagogic fashion. At graduation level in engineering, it is important to encourage the students to acquire perceptions about the relation existent between actions and deformations of a given framed structure under a given pattern loading. The deflections can be determined precisely and the redundant actions are known by hand work, spite to access directly the set of data localized at suitable tables of reference textbooks. We think that, in academic terms and for academic problems, the analyst must know the complete process to calculate them, precisely, without computers and reference tables. The second one is about the characteristic of Flexibility Method. With it, the analyst can choose alternative paths to implement the compatibility equations associated with the supports configurations. Then, he uses the superposition principle to calculate de deflections and rotations. The third one is that this method represents a good opportunity for the students to learn the basis for the Force Method...

Coffee flavor is a mixture of volatile components found in the oil obtained from the roasted coffee. Soluble coffee loses part of its aroma due to processing conditions which could be reintroduced to the product by the direct addition of the coffee oil. However, some studies point out difficulties in obtaining good results when working with in natura oil because of the high volatility and the flavor degradation. The incorporation of nanocapsules containing coffee oil could be an alternative to minimize these losses, because the encapsulating polymer could act as a protecting barrier and promote its controlled release. The aim of this work is obtain PLLA nanocapsules containing roasted coffee oil by the miniemulsification/solvent evaporation technique. The spectrophometric UV- Vis method used to quantify the coffee oil was validated. Formulations with different PLLA and oil concentrations and kind of surfactant were evaluated in respect to the average nanocapsules size and polydispersion index and oil recovery. All formulations demonstrated oil recovery values above 80 % demonstrating that the technique is adequate and can be consider a promising alternative to coffee oil nanocapsules production.

The connection of wind generation to distribution systems can cause power quality problems such as voltage sags and voltage fluctuations. The wind generation can also detrimentally affect the operational and control strategies employed in the distribution systems. On the other hand, the use of suitable control strategies may allow wind generation to mitigate power quality problems related to voltage regulation and to improve the reliability of distribution systems. In this context, this work proposes strategies for coordinated voltage control in distribution systems with wind generation. The proposed control strategies aim at enabling wind generation to contribute to coordinated voltage regulation in the distribution system. The proposed coordinated control with the typical operations of On Load Tap Changer (OLTC) transformers and switched capacitor bank, allows the wind power attenuates voltage variations and voltage fluctuations caused by normal changes in system load and wind speed. The focus of this work is the voltage regulation at the medium voltage bus in the substation, considering the connection of wind generation at this point the system. Control strategies involving the prediction of wind speed are also proposed to improve the performance of the voltage control system...

Encouraging distributed generation is a worldwide trend to diversify and strengthen the network of power generation. The normative number 482, 2012, reduces bureaucracy in accessing micro and mini single phase distributed generators to the power grid, allowing residential consumers act as electric power generators elements. Among the forms of renewable primary energy available in nature, wind and solar are the most promising for generating residential units. This paper presents a unified approach to connecting a unit of micro generation to the single-phase weak grid via AC-DC-AC converter. A structure of connection allows the adjustment of the DC bus voltage and the output current is defined. It is proposed a control structure in the synchronous reference frame (dq), whose reference voltage is fixed at the common connection point. The dq magnitudes synchronization is obtained by means of an estimator based on Kalman filter with fixed gains. The mathematical model of the single phase connection step in the time domain is determined, both in static as in the synchronous reference frame. The mathematical approach in the complex domain is also considered. Based on the principle of superposition, the frequency responses of the variables of the proposed generation system are determined. The parameterization of the controllers is performed considering a dynamic system of reduced order model based in the synchronous reference frame. The state equations of the controllers are included in the plant model...

This work presents an approach to control demand for residential low voltage consumers, aiming to improve energy efficiency in Smart Grids. Initially, an emulator of residential electric loads is modeled based on the literature. The emulator consists of a reservoir for water heating model, the model of an air conditioner and also models of consumption for lighting, televisions and a refrigerator. The implementation and simulation were performed using software Matlab. The demand control algorithms are investigated in order to verify its performance when applied to the set of residential loads. These algorithms typically perform control demand from a system of priorities. Still, from this analysis it demonstrates that these algorithms consider levels of user comfort, but do not allow the drive of two or more loads in the same period of residence if the demand exceeds the limit. Therefore, we propose a control algorithm that uses Rosenbrock search of demand adaptive method, aiming to overcome these limitations. The proposed procedure performs the operation of residential loads gradually considering priority levels and parameters of comfort of users. It is shown through simulations and experiments using the proposed method can perform the activation of several concurrently loads...

The insertion and expansion of distributed generation bring about intrinsic challenges, especially concerning to the reliability and operation of the electric power system, which results in a paradigm shift imposed on power distribution systems. Among the challenges and opportunities associated to distributed generation, the islanded operation of distribution systems and microgrids has grown considerably. In this context, this paper proposes operational and control strategies to properly allow the operation of a wind generation system. The proposed control is based on a supplementary control loop, added to the speed control loop of the wind turbine. The proposed control loop consists of a paradigm shift to control the DC-link voltage, since in traditional systems the DC-link voltage is usually controlled only by the BESS. The proposed supplementary control loop reduces the number and duration of the BESS actuations. Furthermore, the proposed strategy can contribute to enhance the reliability and the life cycle of the energy storage device. This work also proposes a new methodology for minimum sizing of battery energy storage systems to allow the islanded operation of wind power systems. The methodology considers a maximum load step to be supplied by the system. Finally...

The world market of polysaccharides has attracted large industrial companies interested in gaining new and profitable fields. Polysaccharides with technological and biological properties can be obtained from plants, algae and microorganisms. Among the polysaccharides with biological properties, glucans have been highlighted by demonstrate immunostimulatory activity and potential for treating diseases such as cancer, hypercholesterolemia, diabetes, multiple sclerosis and cardiovascular diseases. Recent studies demonstrate the production of exocellular β-glucans by filamentous fungi in submerged cultivations. Modifications in the chemical structure of glucans by carboxymethylation is considered an important route to improve its properties, may contribute to the increased solubility of the molecule as well as biological activities, especially those associated with antioxidant and antiproliferative mechanisms of action. Therefore, the present work aimed the production of β-1,6-D glucan (lasiodiplodana) by the Lasiodiplodia theobromae MMPI fungus in submerged cultivation and carboxymethylation of the molecule, characterization and evaluation of cytotoxicity and antioxidant activity. The carboxymethylation of the molecule was confirmed by checking specific chemical signals identified by FT-IR and NMR and 13C spectroscopy. Carboxymethylated molecule presented degree of substitution (DS) of 1.27. Thermal analysis (TG / DTA) indicated that native and carboxymethylated samples had four stages of mass loss. The first stage was at 125 ºC (loss of water) and there were two consecutive events of weight loss (200 ºC - 400 ºC) attributed to the degradation of the molecule. The fourth stage occurred between 425 ºC and 620 ºC (final decomposition) with exothermic peak at 510 ºC. SEM analysis indicated that the raw lasiodiplodan presents granular structures which are broken after carboxymetylation. XRD analysis showed that native and carboxymethylated biopolymers have no crystalline structure. Carboxymethylation aided to improve water solubility the molecule (60% increase) and to improve antioxidant activity assessed by ability to capture the ABTS...
