Forró eletrônico: uma análise sobre a representação da figura feminina

Understanding music as a social manifestation, able to represent the time and culture along with their uses and mores, we look at the female figure in the electronic forró genre. Through a reading of the two genres musical and feminine we seek to identify the discourses present in the compositions, which refer to the feminine with thematic and/or terms referring to women. The study focuses on the compositions between 2009 to 2010 which became hits, ie.: those which have attained the highest number of listeners to 96 FM in a program named Paradão 96, broadcasted daily in the city of Natal/RN. Grounded in such concepts as cultural industry, mass culture, folkcommunication and gender, we analyze the processes of meaning production as a result of using the female figure and more accurately, about the representation of women through the discourse of this specific genre. We have chose the descriptive research with a qualitative approach and Discourse Analysis as a technique to identify the terms that refer to women, reflecting on what would be the possible meanings found in these speeches. We point out that in our investigation the female figure turned into a sexual object, erotic and submissive, in their turn, attributes usually given to women, was not a predominant result in the speech of electronic forró gender. With a variant thematic some playful and others about the betrayal of women we have identified that, to the surprise of many, including ourselves, romantic love was the one who led the audience requests during our time frame and that the female figure has several facets within the studied genre

Aditivos de formulação na formação de filmes isolados de etilcelulose. estudos físico-químicos e morfológicos

Formulation Additives on Formation of Films isolated from Ethylcellulose. Physicochemical and Morphological Studies. In this work were developed free films from Surelease (R), additives alpha-GOS (alfa-glucooligosaccharide) and/or Tween (R) 80 in aqueous solution. It was obtained by Teflon plates casting process. The free films were characterized by thermal analysis (DSC and TGA), infrared spectroscopy (FTIR-ATR) and scanning electron microscopy (SEM). DSC and TO analysis showed that the additives do not influenced in the thermal stability of Surelease (R) films. SEM analysis observed homogeneous morphological characteristics and phase detachment absence. FTIR-ATR spectra were used to confirm the physical mixture between the components of films.

Phytase immobilization on modified electrodes for amperometric biosensing

Phytase (myo-inositol hexaphosphate phosphohydrolase) and phytic acid (myo-inositol hexaphosphate) play an important environmental role, in addition to being a health issue in food industry. Phytic acid is antinutritional due to its ability to chelate metal ions and may also react with proteins decreasing their bioavailability. In this work, we produced biosensors with phytase immobilized in Layer-by-Layer (LbL) films, which could detect phytic acid with a detection limit of 0.19 mmol L-1, which is sufficient to detect phytic acid in seeds of grains and vegetables. The biosensosrs consisted of LbL films containing up to eight bilayers of phytase alternated with poly(allylamine) hydrochloride (PAH) deposited onto an indium-tin oxide (ITO) substrate modified with Prussian Blue. Amperometric detection was conducted in an acetate buffer solution (at pH 5.5) at room temperature, with the biosensor response attributed to the formation of phosphate ions. In subsidiary experiments with the currents measured at 0.0 V (vs. SCE), we demonstrated the absence of effects from some interferents, pointing to a good selectivity of the biosensor.

Europium luminescent polymeric microspheres fabricated by spray drying process

The spray drying method was used to prepare luminescent microspheres. These microspheres were prepared by spraying an aqueous solution of dextrin and an europium(III) complex with subsequent drying in a hot medium. The spray dried powder was characterized by scanning electron microscopy (SEM) and photoluminescence spectroscopy (PL). Particle size distribution was estimated from SEM images. The ultrasonic spray drying technique was successfully applied to yield a microparticulated and red luminescent powder composed by the [Eu(dpa)(3)](3-) stop (dpa = dipicolinic acid) complex incorporated in dextrin microspheres.

Partial characterization of proteins from baru (Dipteryx alata Vog) seeds

BACKGROUND: Baru (Dipteryx alata Vog.) is a fruit distributed throughout the Brazilian savanna and contains a seed with a high protein content, whose properties have been rarely explored. The purpose of this study was to characterize this protein, especially by isolation and quantifying its fractions and measuring some of its molecular properties.RESULTS: Baru seeds contain 244 g kg(-1) protein on a dry weight basis. Solubility profiles showed a preponderance of globulins. This fraction dominated the seed composition, with 61.7 wt% of the total soluble proteins. Albumins and glutelins accounted for 14 and 3.3 wt%, respectively. SDS-PAGE resolution of albumin and globulin showed main bands with molecular weights of 84 kDa and 64,66 and 73 kDa, respectively. The total protein of the flour and the globulin showed values of in vitro digestibility of 85.59% and 90.54%, relative to casein. Total globulin produced only one chromatographic peak, both on Sepharose CL-6B gel filtration and on DEAE-cellulose ion-exchange columns, eluted at a concentration of 0.12 mol L(-1) NaCl.CONCLUSION: The baru seed had high protein content with large quantities of storage proteins. The chromatographic and solubility profiles indicate the predominance of a fraction with characteristics of a legumin-type protein. (C) 2011 Society of Chemical Industry

São Vicente (RN) nos primeiros anos da TV: Memória, sociabilidade e cotidiano

The present work aims to reflect on the everyday and its Vincentian practices of sociability in the early years of the presence of television in the city of São Vicente (RN), from the memories of the protagonists who witnessed the first insertion of TV set sin the beginning sof 1970s.Thus, the research was guided by some questions deemed relevant to the study in order to understand the most significant changes in the daily Vincentian boosted by the arrival of television in some private houses, which soon became a meeting place, recreation and sociability. At that time, filled the role of TV unites and brings people together. These houses, reinvented in spaces of sociability, were sanctioned by the various actors who gathered daily to include television programming. This popularity of television was measured by the joint efforts of people who moved their homes to homes that had this technical device. Each home with their uniqueness sand peculiarity, which attracted the population frequency f these spaces were frequent. Of course people still sit on the sidewalks, to be held the night rides in the streets and square, but soon came to the program schedule Preferred came into leaving their homes or to homes that had TV, watch them in the design of audiovisual programs. We use the oral memory as the principal methodology in order to interpret the memories recounted by people who lived in that time period studied. For this purpose we constructed a narrative that highlights the categories memory, media, social practices, everyday life and thus has the theoretical and methodological contributions of authors of humanities and social sciences its main foundation. In field research in the use of in-depth interviews, since the narratives of our research is interviewed. The importance of a study of such order, is not only in understanding the TV as an essential mediator for the interaction of individuals in society, from 1970 in São Vicente (RN), but also for the unveiling of his relationship with the daily routines of the Vincentians, founded in environments and symbols that regulated the conduct and reordered the social practices and sociability of these subjects. In this sense, the making of a work on the presence of TV in the city of São Vicente (RN) is also of paramount importance for the history of this media at the national level, since this is nothing more than a set of multiple stories

Forró eletrônico: uma análise sobre a representação da figura feminina

Entendiendo la música como una manifestación social, capaz de representar el tiempo y la cultura, junto con sus usos y costumbres, dirigimos nuestra mirada en la figura femenina presente en el género forró electrónico. A través de la lectura de los dos géneros musical y femenino buscamos identificar los discursos, presentes en las composiciones, que se refieren a lo femenino con temática y/o términos que se refieren a las mujeres. El estudio se centra en las composiciones en el período 2009 a 2010 y que se convirtieron en éxitos, es decir, aquellos que han alcanzado el mayor número de oyentes de Radio 96 FM a través del programa Paradão 96, transmitido diariamente en la ciudad de Natal/RN. Basado en conceptos tales como industria cultural, cultura de masas, folkcomunicación y género, se analizan los procesos de producción de sentido como resultado del uso de la figura femenina y con mayor precisión, sobre la representación de las mujeres a través de discursos del forró electrónico. Elegimos el enfoque descriptivo cualitativo y análisis del discurso como una técnica para identificarlos términos que se refieren a las mujeres, reflexionando sobre los posibles significados que se encuentran en estos discursos. Se señala que en nuestra investigación no predominó una figura femenina convertida en un objeto sexual, erótico y sumisa, atributos dados para las mujeres, en los discursos de forró electrónico. Con variaciones en las temáticas algunas juguetones y otras acerca de la traición de la mujer identificamos que, para sorpresa de muchos, incluidos nosotros, el amor romántico fue el que llevó las solicitudes de audiencia durante nuestro período de tiempo y que la figura femenina tiene varias facetas dentro del forró electrónico
