Composição química e atividade antioxidante de maracujá-roxo (Passiflora edulis Sims edulis)em diferentes graus de maturação

O maracujá-roxo é um fruto tropical que tem ganho destaque devido ao seu valor nutricional, organolético e às emergentes descobertas acerca das suas propriedades farmacêuticas e antioxidantes. Durante o processo de maturação decorrem várias reações de ordem física e química, e no intuito de enriquecer o conhecimento acerca de como a composição química e as propriedades do maracujá-roxo evoluem ao longo da maturação, este trabalho consistiu na caracterização física do fruto inteiro e na caracterização química geral das sementes, casca e polpa em frutos separados em cinco graus de maturação diferentes (G1 a G5). Foi também avaliada a atividade antioxidante (atividade antiradicalar e poder redutor), e o teor em compostos fenólicos (fenóis totais, derivados do ácido hidroxicinâmico e flavonóis) das diferentes matrizes que compõem o fruto ao longo da maturação. A partir dos resultados obtidos verificou-se na casca que o teor em cinza bruta aumenta essencialmente entre G1 e G2 enquanto se verificou uma diminuição da proteína. Em relação à semente, o teor em cinza bruta aumenta gradualmente, e o teor em proteína aumenta de G1 para G2, estabilizando posteriormente nos 8% (base seca). O teor em gordura aumenta gradualmente ao longo da maturação, verificando-se um maior acumulo entre G1 e G2 (9,9 e 19,1% respetivamente). No que respeita à polpa, há uma diminuição nos teores de cinza e proteína e aumento dos sólidos solúveis totais.Verificou-se um aumento ligeiro do pH ao longo da maturação (entre 2,8 a 3,1) e uma diminuição da acidez (entre 12,1 e 6,7 g de ácido cítrico 100 mL-1). Constatou-se que os açúcares predominantes na polpa foram a sacarose, frutose e glucose. Quanto aos ácidos orgánicos, o ácido cítrico foi o maioritário em todos os graus de maturação e teores mais baixos foram quantificados para os ácidos málico e ascórbico. Entre as diferentes partes do fruto estudadas, as cascas foram a matriz mais antioxidante, aumentando o seu potencial bioativo durante a maturação. As sementes apresentaram valores mais elevados de fenóis totais, derivados do ácido hidroxicinâmico e flavonóis. Foi verificado que a atividade antioxidante esteve correlacionada com os valores de fenóis totais presentes nas diferentes partes do fruto ao longo da maturação. De acordo com o conhecimento dos autores, este é o primeiro estudo que toma em consideração as alterações sofridas pelas diferentes partes do maracujá-roxo produzido em Portugal, ao longo da maturação.

El postgrado para el acceso a la profesión de abogado: seguimiento y balance en la Universidad de Oviedo

La Ley 34/2006 y su reglamento de desarrollo, aprobado por Real Decreto 775/2011, introdujeron una reforma esencial en el acceso a la profesión de abogado en España, para cuyo ejercicio había bastado tradicionalmente con la Licenciatura de Derecho, pasando a exigir la realización de estudios de postgrado y prácticas externas para lograr una capacitación profesional, a la postre evaluada con una prueba estatal unificada. Tras obtener la verificación de la ANECA en la modalidad de “formación impartida conjuntamente por las Universidades y las Escuelas de práctica jurídica”, el Máster Universitario en Abogacía de la Universidad de Oviedo, con la participación de los colegios profesionales de abogados de Oviedo y de Gijón, se implantó en 2012/2013. Una vez graduados los integrantes de la primera promoción, procede reflexionar sobre la consecución de objetivos y plantear cuantas modificaciones sean necesarias para asegurar mejoras notables en el futuro; propuestas que pueden resultar exportables a otros postgrados de este tipo. Tal es el objetivo del presente trabajo que, desde la experiencia atesorada por su autora como miembro de la Comisión Académica y secretaria de la Comisión de Calidad del citado Máster, analiza la experiencia cubriendo vertientes que van desde la planificación y coordinación docente a la evaluación de competencias.

Síntese e impregnação de peneiras moleculares Fe MCM-41 derivada de sílica da casca do arroz

The mesoporous molecular sieves of the MCM-41 and FeMCM-41 type are considered promissory as support for metals used as catalysts in oil-based materials refine processes and as adsorbents for environmental protection proposes. In this work MCM-41 and FeMCM41 were synthesized using rice husk ash - RHA as alternative to the conventional silica source. Hydrothermal synthesis was the method chosen to prepare the materials. Pre-defined synthesis parameters were 100°C for 168 hours, later the precursor was calcinated at 550°C for 2 hours under nitrogen and air flow. The sieves containing different proportions of iron were produced by two routes: introduction of iron salt direct synthesis; and a modification post synthesis consisting in iron salt 1 % and 5% impregnation in the material followed by thermal decomposition. The molecular sieves were characterized by X ray diffraction XRD, Fourier transform infrared spectroscopy FT-IR, X ray fluorescence spectroscopy XFR, scanning electronic microscopy SEM, specific surface area using the BET method, Termogravimetry TG. The kinetic model of Flynn Wall was used with the aim of determining the apparent activation energy of the surfactant remove (CTMABr) in the MCM- 41 porous. The analysis made possible the morphology characterization, identifying the presence of hexagonal structure typical for mesoporous materials, as well as observation of the MCM41 and iron of characteristic bands.

Otimização e análise mecânica de pastas geopoliméricas para uso em poços sujeitos à injeção cíclica de vapor

Oil wells subjected to cyclic steam injection present important challenges for the development of well cementing systems, mainly due to tensile stresses caused by thermal gradients during its useful life. Cement sheath failures in wells using conventional high compressive strength systems lead to the use of cement systems that are more flexible and/or ductile, with emphasis on Portland cement systems with latex addition. Recent research efforts have presented geopolymeric systems as alternatives. These cementing systems are based on alkaline activation of amorphous aluminosilicates such as metakaolin or fly ash and display advantageous properties such as high compressive strength, fast setting and thermal stability. Basic geopolymeric formulations can be found in the literature, which meet basic oil industry specifications such as rheology, compressive strength and thickening time. In this work, new geopolymeric formulations were developed, based on metakaolin, potassium silicate, potassium hydroxide, silica fume and mineral fiber, using the state of the art in chemical composition, mixture modeling and additivation to optimize the most relevant properties for oil well cementing. Starting from molar ratios considered ideal in the literature (SiO2/Al2O3 = 3.8 e K2O/Al2O3 = 1.0), a study of dry mixtures was performed,based on the compressive packing model, resulting in an optimal volume of 6% for the added solid material. This material (silica fume and mineral fiber) works both as an additional silica source (in the case of silica fume) and as mechanical reinforcement, especially in the case of mineral fiber, which incremented the tensile strength. The first triaxial mechanical study of this class of materials was performed. For comparison, a mechanical study of conventional latex-based cementing systems was also carried out. Regardless of differences in the failure mode (brittle for geopolymers, ductile for latex-based systems), the superior uniaxial compressive strength (37 MPa for the geopolymeric slurry P5 versus 18 MPa for the conventional slurry P2), similar triaxial behavior (friction angle 21° for P5 and P2) and lower stifness (in the elastic region 5.1 GPa for P5 versus 6.8 GPa for P2) of the geopolymeric systems allowed them to withstand a similar amount of mechanical energy (155 kJ/m3 for P5 versus 208 kJ/m3 for P2), noting that geopolymers work in the elastic regime, without the microcracking present in the case of latex-based systems. Therefore, the geopolymers studied on this work must be designed for application in the elastic region to avoid brittle failure. Finally, the tensile strength of geopolymers is originally poor (1.3 MPa for the geopolymeric slurry P3) due to its brittle structure. However, after additivation with mineral fiber, the tensile strength became equivalent to that of latex-based systems (2.3 MPa for P5 and 2.1 MPa for P2). The technical viability of conventional and proposed formulations was evaluated for the whole well life, including stresses due to cyclic steam injection. This analysis was performed using finite element-based simulation software. It was verified that conventional slurries are viable up to 204ºF (400ºC) and geopolymeric slurries are viable above 500ºF (260ºC)

Obtenção de filtro cerâmico a partir da diatomita e casca de arroz carbonizada visando tratamento de efluente têxtil

The effluents released by the textile industry have high concentrations of alkali, carbohydrates, proteins, in addition to colors containing heavy metals. Therefore, a filter was prepared aiming primarily to the removal of color. In order to prepare this filter, rice hulls and diatomite were used, which have in their structure, basically amorphous hydrated silica. The silica exists in three crystalline forms: quartz, tridymite and cristobalite. In accordance with the above considerations, this study was divided into two stages; the first corresponds to the preparation of the filter and the second to carry out the tests in the effluent/filter in order to verify the efficiency of the color removal. First, the raw material was subjected to a chemical analysis and XRD, and then the diatomite was mixed, via humid, with a planetarium windmill with 20 %, 40 %, 60 % and 80 % of rice husk ash. To the mixture, 5 % carboxymethylcellulose (CMC) was added as a binder at room temperature. The samples were uniaxially compacted into metallic matrix of 0.3 x 0.1 cm² of area at a pressure of 167 MPa by means of hydraulic press and then sintered at temperatures of 1,000 °C, 1,200 °C and 1,400 °C for 1 h and submitted to granulometry test using laser, linear retraction, water absorption, apparent porosity and resistance to bending, DTA, TMA and XRD. To examine the pore structure of the samples scanning electron microscope (SEM) was used. Also tests were carried out in a mercury porosimeter to verify the average size of the pores and real density of the samples. In the second stage, samples of the effluent were collected from a local industry, whose name will be preserved, located in Igapó, in the State of Rio Grande do Norte - RN. The effluent was first pretreated before filtration and then subjected to a treatment of flotation. The effluent was then characterized before and after filtration, with parameters of color, turbidity, suspended solids, pH, chemical and biochemical oxygen demand (COD and BOD). Thus, through the XRD analysis the formation of cristobalite α in all samples was observed. The best average size of pore was found to be 1.75 μm with 61.04 % apparent porosity, thus obtaining an average 97.9 % color removal and 99.8 % removal of suspended solid

Adição do resíduo de biomassa da cana-de-açúcar em pastas para cimentação de poços petrolíferos produtores de óleos pesados

The Potiguar basin has large fields of viscous oil where the used method for recovering is based on vapor injection; this operation is carried out by injecting vapor in the oilwell directly, without the protection of a revetment through thermal insulation, what causes its dilation and, consequently, cracks in the cement placed on the annular, and lost of hydraulic insulation; this crack is occasioned by the phenomenon of retrogression of the compressive resistance due to the conversion of the hydrated calcium silicate in phases calcium-rich, caused by the high temperatures in the wells, subjected to thermal recuperation. This work has evaluated the application of composite pastes with addition of residue of biomass of ground sugar-cane bagasse as anti-retrogression mineral admixture for cementation of oil-wells subjected to thermal recuperation. The addition of the mineral residue was carried out considering a relative amount of 10, 20, 30, 40 and 59% in relation to cement mass, trying to improve the microstructure of the paste, still being developed a reference paste only with cement and a paste with addition of 40% of silica flour - renowned material in the oil industry as anti-retrogression additive. Pozzolanic activity of the ash was evaluated through XRD, TG/DTG, as the resistance to compression, and it was also determined the physical and mechanical behavior of the pastes when submitted to cure at low temperatures (22 and 38º C); besides it was evaluated the behavior of the pastes when submitted to two cycles of cure at high temperature (280ºC) and pressure (7 MPa). It was verified that the ash of the sugar-cane biomass presents pozzolanic reaction and has great efficiency in decrease the permeability of the paste by filler effect, as well as that addition of ash in a relative amount of 10, 20 e 30% increases cured compressive resistance at low temperatures. It was also showed that the ash in a relative amount of 40% and 59% has very significant efficiency as anti-retrogression additive, since it prevents the decrease of compressive resistance and forms hydrated calcium silicate type xenotlita and tobermorita which have more resistance and stability in high temperatures

Mesoestruturas porosas a partir de materiais naturais

The MCM-41 mesoporous synthesis was done using rice hulls ash and chrysotile as natural alternative silica sources. For the using of these sources, chemical and thermic treatments were done in both materials. After chemical and thermic treatments, these materials were employed on the MCM-41 mesoctructures synthesis. The natural materials treated and employed in the synthesis were characterized by several techniques such as X-ray diffraction, N2 adsorption and desorption, scanning electronic microscopy and thermogravimetric analysis. MCM-41 standart samples synthetized with aerosil 200 commercial sílica were used to evaluation. The formed material from rice hulls ash showed values from BET specific area about 468 m².g-1, N2 adsorption and desorption isotherms and loss mass similar to reference materials. The silica from chrysotile calcined and leached was employed to mesoporous materials synthesis. The BET specific area showed values about 700 m².g-1, N2 adsorption and desorption isotherms type IV and loss mass similar to mesoporous materials. The formed material from calcined and leached chrysotile, without calcination, applied to phenol remotion carried high performance liquid chromatography and evaluated with organophilic clays with different treatments. By the characterization techniques were proved that mesoporous materials with lesser order that reference samples. The material formed from rice hulls ash without the calcination step achieved better adsorption results than organophilic clays

Síntese de pigmento cerâmico ferrita de cobalto utilizando planejamento experimental

Synthetic inorganic pigments are the most widely used in ceramic applications because they have excellent chemical and thermal stability and also, in general, a lower toxicity to man and to the environment. In the present work, the ceramic black pigment CoFe2O4 was synthesized by the polymerization Complex method (MPC) in order to form a material with good chemical homogeneity. Aiming to optimize the process of getting the pigment through the MPC was used a fractional factorial design 2(5-2), with resolution III. The factors studied in mathematical models were: citric acid concentration, the pyrolysis time, temperature, time and rate of calcination. The response surfaces using the software statistica 7.0. The powders were characterized by thermal analysis (TG/DSC), x-ray diffraction (XRD), scanning electron microscopy (SEM) and spectroscopy in the UV-visible. Based on the results, there was the formation of phase cobalt ferrite (CoFe2O4) with spinel structure. The color of the pigments obtained showed dark shades, from black to gray. The model chosen was appropriate since proved to be adjusted and predictive. Planning also showed that all factors were significant, with a confidence level of 95%

Estudo da potencialidade da incorporação de resíduo de granito e da queima da casca do café em cerâmica vermelha

The industrial production of ornamental rocks and the burning of coffee husk generate waste that is discarded into the environment. However, with the study of the incorporation of these residues in ceramic products, may be found an alternative to reducing environmental impacts and detrimental effects on human health caused by its indiscriminate disposal of waste in nature. Thus, this work aimed to study the addition of ashes of the coffee husk and granite residue in matrix of red ceramic. The raw materials were dry milled and sieved to mesh 100. To characterize the raw materials were carried out analyzes of X-ray diffraction (XRD), X-ray fluorescence (XRF), particle size analysis (PSA), differential thermal analysis (DTA) and thermogravimetric analysis (TG). Six formulations were prepared where the clay content was kept constant (70%wt) and ashes contents and granite residue varied from 10, 15, 20 and 30%. Dilatometrics analyzes were performed at four selected formulations, containing them: 100% clay (A100); 70% clay and 30% ashes (A70C30); 70% clay and 30% granite residue (A70G30); and 70% clay, 15% granite residue and 15% ashes (A70G15C15). The samples were prepared by uniaxial compaction with pressure of 25 MPa, and fired at temperatures of 800°C, 850ºC, 900ºC, 950ºC, 1000ºC and 1100°C. Assays were performed to determine the linear shrinkage of burning (LSB), water absorption (WA), apparent porosity (AP), density (D) and tensile bending. Also were performed analyzes of X-ray diffraction (XRD) and scanning electron microscopy (SEM) of the samples fired. The formulations incorporating granite residue and/or ashes reached the required limits of water absorption according to NBR 15270-1 and NBR 15310 and tensile bending according to classical literature (SANTOS, 1989) necessary for the production of tiles and ceramic block for masonry sealing

Estratégias para intervenções de reparação e reforço em estruturas de betão armado

Já se passaram algumas décadas desde que o betão é o principal material de construção que ergue cidades e estruturas nas civilizações contemporâneas. Num passado não muito longínquo, a área da durabilidade, manutenção e prevenção das estruturas de betão não foi vista como prioridade, chegando a ser negligenciada, por consequência hoje existem graves problemas nalgumas construções de betão. Por outro lado, devido ao excedente de construção habitacional em Portugal e à, a atual conjuntura económica/financeira que a Europa atravessa, o setor da construção tem sofrido um abrandamento acentuado. A consciência e postura de sustentabilidade das novas gerações e entidades competentes, acentuou a necessidade de preservar, reparar e reforçar muito do património no parque habitacional português e europeu. O projeto de intervenção numa estrutura nunca é abordada da mesma maneira, não existem duas estruturas iguais, e há particularidades neste tipo de projetos que não existem num projeto de uma estrutura nova. Para intervir numa estrutura já construída é necessário um conhecimento abrangente em várias temáticas, tais como: regulamentação, métodos de avaliação de segurança, definição das características mecânicas dos materiais, técnicas de reparação e reforço, metodologias de diagnostico e intervenção, comportamento estrutural, etc. Atualmente existe muita informação acerca da temática de reparação e reforço de estruturas de betão armado, no entanto há ainda alguma falta de documentação onde a informação aparece de forma integral e objetiva. Consideando o apresentado anteriormente, tentou-se compilar informação sobre os principais assuntos que interessam a um projeto de reparação/reforço de estruturas de betão armado, nomeadamente as normas e legislação aplicável, exemplos de metodologias de inspeção e intervenção, os principais ensaios em laboratório e in situ para caracterização dos materiais, principais técnicas de reparação/reforço. Sobre este tópico e a título de exemplo, aprofundou-se com mais detalhe as considerações relativas ao dimensionamento com reforço com FRP´s.
