In order to differentiate and characterize Madeira wines according to main grape varieties, the volatile composition (higher alcohols, fatty acids, ethyl esters and carbonyl compounds) was determined for 36 monovarietal Madeira wine samples elaborated from Boal, Malvazia, Sercial and Verdelho white grape varieties. The study was carried out by headspace solid-phase microextraction technique (HS-SPME), in dynamic mode, coupled with gas chromatography–mass spectrometry (GC–MS). Corrected peak area data for 42 analytes from the above mentioned chemical groups was used for statistical purposes. Principal component analysis (PCA) was applied in order to determine the main sources of variability present in the data sets and to establish the relation between samples (objects) and volatile compounds (variables). The data obtained by GC–MS shows that the most important contributions to the differentiation of Boal wines are benzyl alcohol and (E)-hex-3-en-1-ol. Ethyl octadecanoate, (Z)-hex-3-en-1-ol and benzoic acid are the major contributions in Malvazia wines and 2-methylpropan-1-ol is associated to Sercial wines. Verdelho wines are most correlated with 5-(ethoxymethyl)-furfural, nonanone and cis-9-ethyldecenoate. A 96.4% of prediction ability was obtained by the application of stepwise linear discriminant analysis (SLDA) using the 19 variables that maximise the variance of the initial data set.

Andryala (Asteraceae: Cichorieae) is a little-known Mediterranean-Macaronesian genus whose taxonomy is much in need of revision. The aim of the present biosystematic study was to elucidate species relationships within this genus based on morphological and molecular data. In this study several taxa are recognised: 17 species, 14 subspecies, and 3 hybrids. Among these, 5 species are Macaronesian endemics (A. glandulosa, A. sparsiflora, A. crithmifolia Aiton, A. pinnatifida, and A. perezii), 4 species are Northwest African endemics (A. mogadorensis, A. maroccana, A. chevallieri, and A. nigricans) and one species is endemic to Romania (A. laevitomentosa). Historical background regarding taxonomic delimitation in the genus is addressed from Linnaean to present day concepts, as well as the origin of the name Andryala. The origin of Asteraceae and the systematic position of Andryala is shortly summarised. The morphological study was based on a bibliographic review and the revision of 1066 specimens of 13 herbaria as well as additional material collected during fieldwork. The variability of the morphological characters of the genus, including both vegetative taxonomic characters (root, stem, leaf and indumentum characters) and reproductive ones (inflorescence, floret, fruit and pappus characters), is assessed. Numerical analysis of the morphological data was performed using different similarity or dissimilarity measures and coefficients, as well as ordination and clustering methods. Results support the segregation of the recognised taxa and the congruence of the several analyses in the separation of the recognised taxa (using quantitative, binary or multi-state characters). The proposed taxonomy for Andryala includes a new infra-generic classification, new taxa and new combinations and ranks, typifications and diagnostic keys (one for the species and several for subspecies). For each taxon a list of synonyms, typification comments and a detailed description are provided, just as comments on taxonomy and nomenclature, and a brief discussion on karyology. Additionally, information on ecology and conservation status as well as on distribution and a list of studied material are also presented. Phylogenetic analyses based on different nuclear and chloroplast DNA markers, using Bayesian and maximum parsimony methods of inference, were performed. Results support three main lineages: separate ones for the relict species A. agardhii and A. laevitomentosa and a third including the majority of the Andryala species that underwent a relatively rapid and recent speciation. They also suggest a single colonization event of Madeira and the Canary Islands from the Mediterranean region, followed by insular speciation. Biogeography and speciation within the genus are briefly discussed, including a proposal for the centre of origin of the genus and possible dispersal routes.

The goal of the research was to investigate the energy performance of residential vertical buildings envelope in the hot and humid climate of Natal, capital of Rio Grande do Norte, based in the Technical Regulation of Quality for Energy Efficiency Level in Residential Buildings (RTQ -R), launched in 2010. The study pretends to contribute to the development of design strategies appropriate to the specific local climate and the increasing of energy efficiency level of the envelope. The methodological procedures included the survey in 22 (twenty two) residential buildings, the formulation of representative prototypes based on typological and constructives characters researched and the classification of the level of energy efficiency in the envelopment of these prototypes, using as a tool the prescriptive method of the RTQ-R and the parametric analyzes from assigning different values of the following variables: shape of the pavement type; distribution of housing compartments; orientation of the building; area and shading of openings; thermal transmittance, and solar absorptance of opaque materials of the frontage in order to evaluate the influence of these on the envelopment performance. The main results accomplished with this work includes the qualification of vertical residential buildings in Natal/RN; the verification of the adequacy of these buildings to local climate based from the diagnosis of the thermal energy of the envelopment performance, the identification of variables with more significant influence on the prescriptive methodology of RTQ-R and design solutions more favorable to obtain higher levels energy efficiency by this method. Finally, it was verified, that some of these solutions proved contradictory in relation to the recommendations contained in the theoretical approaches regarding environmental comfort in hot and humid weather, which indicates the need for improvement of the prescriptive method RTQ-R and further research on efficient design solutions

In Brazil, the Free Political advertising time (HGPE) represents one of the main venues for the contest between political parties, revealing a tool that streamlines the electoral dispute and enables all sectors and social classes of important information about dispute over candidates. In HGPE, political groups have the opportunity to present their programs of government and discuss issues that relate to the demands of the population. This research sought to examine the role played by so-called "government programs" in the electoral race for governor of Rio Grande do Norte in 2006, which had as main candidates, two traditional characters of the political landscape in Natal: Wilma de Faria (PSB) and Garibaldi Alves Filho (PMDB). According to our analysis, discussion of government programs such candidates in HGPE had not meant to enlighten the voters about the political projects designed, not just the desire to build an image of seriousness and competence of candidates, but appeared as a means to meet the schedule imposed by the opponent and as a strategic resource to select a specific segment of the electorate.

Pathogens in seeds imply quarantine constraints for exportation. This research aimed to quantify nematodes and fungus populations in seed samples of forage grasses from the main Brazilian producing states, and to multiply the nematodes in vitro, as well to study the taxonomy of the nematodes detected. Seed samples of 237 lots of different forage grasses from São Paulo, Minas Gerais, Mato Grosso do Sul, Mato Grosso, Bahia, and Goias States were collected and shipped for analyses in the Nematology and Plant Pathology Laboratories at FCAV[long dash]UNESP [long dash] Jaboticabal( SP) by Comercio e Industria Matsuda Imp., Exp. Ltd. Nematodes were extracted from 10 g of seeds. To detect the fungus, the Blotter-test was applied. The identifications were done by using a photonic microscope and a stereomicroscope. For the study of in vitro multiplication of the nematodes, the following parthenogenetic species were selected: Aphelenchoides sexlineatus, Aphelenchus sp. and Ditylenchus montanus. Cultures of the fungi Fusarium sp. and Didymella brioniae were used as substrate to multiply the nematodes in Petri dishes. Each plate was inoculated with 10 mature females, then incubated in B.O.D. at 25 [plus or minus]1 [degree]C, in the dark. Thirty days after inoculation, the nematodes were extracted. The populations obtained in the suspensions were estimated in the microscope using Peters counting chamber, and the reproduction factor estimated. For the taxonomic study of the nematodes, morphological characters of specimens were recorded under the light and scanning electron microscopes. The results indicated a large distribution of nematodes and fungus in seeds of forage grasses in Brazil. The nematodes identified in the present study were: Aphelenchoides besseyi, A. bicaudatus, A. fragariae, A. sexlineatus, Ditylenchus myceliophagus, D. dipsaci, D. montanus, and Aphelenchus sp. In addition, species of the fungi Fusarium, Helminthosporium and Phoma were recovered.

This study deals with a historical, descriptive and exploratory approach aiming to recall the origin and trajectory of the Pediatrics Hospital at Universidade Federal do Rio Grande do Norte. This research also deals with the insertion of the nursing department in the same Hospital. This was realized through existing records and discourse collected through interview of professionals-doctors, nurses, midwifes, nursing attendants and psychologists. Thus, a network was established and consisted of qualified informants, composed through reference analysis. Data treatment and analysis was performed based on the collection of oral data. The data was considered according to the font s context, all of which depending on process of comprehension and interpretation. The research was based on the main theme, through oral history used in order to build a historical background. These main themes were then subdivided and other discourses were made present such as: the historical scene, the dream came true and the insertion of nursing, present in the history construction; all of which enabled the research. Thus, in this process, it was possible to identify the most important characters of the origin of children s health services organization and assistance at Rio Grande do Norte. It was possible to perceive that this institution aimed to initiate health services that dealt with an education for future generations. This was observed through the creation of the Faculty of Medicine of Natal and as a consequence, the installation of a Pediatrics Hospital that dealt with medical education. The research made evident that the nursing contributed for a structuring of quality health assistance towards children, even though the resources and working conditions were scarce, extensive work shifts and low professional qualification. It was observed that the there was change in the category s profile, once nurses were introduced in the service. Once this happened, changes in mentality, and innovative processes as well as professional conducts were established. The distinctive relation between acting and doing of doctors and nurses were also dealt with. Thus, the first item is done towards the idealization, projection and prescription. The second issue deals with concretization in realization of something that was not projected and realized, causing suffering and unsatisfaction. At the end, it was possible to confirm that oral history is a very rich element and it is possible through subjects that build history, through their perceptation of the facts and the context in that their are inside

We have been living in a world of packed products. The package and the labels support the companies to communicate with the customers in addition to give protection, storage and convenience in proportion to the products that move in the price list. The labels mainly add up a value which helps the companies differ their products and increase the value of the brands among the final customers. However, the information given in the label are not clear sometimes. It displays a verbal-visual defective language resulted from a poor visibility, legibleness and comprehensibleness of the verbal and visual marks. The aim of this research is to verify, according to the costumers‟ view, the level of the clarity in the informative texts, harmony and ergonomic conformity of the package labels in the chocolate powder of the Claralate brand, considering the linguistic aspects presented on the labels. The criteria to evaluate the chocolate package selected were based on the linguistic field: the organization and the structure of the text derided from the classification of the textual genre; the clarity and the comprehension of the language utilized on those labels. From the ergonomic view, the informative and ergonomic conformity, based on the following requirements: legibility, symbols, characters, reading fields and intermission of the written lines. Therefore, the research done july 2007 and added july 2011 had a structured questionnaire in the interview put to the 118 customers of the chocolate package that go shopping in one of the two supermarkets in Floriano, Piauí São Jorge and/or Super Quaresma. The main results of the investigation show that the linguistic aspects in the informative texts of the labels provide the customers‟ expectancy partially, while the consideration of the informative ergonomic analyzed can contribute to the improvement of the information and consequent visual progress of those, on the labels of chocolate package investigated. As recommendation towards the maker of the product, the outcome of the research indicates: harmonize the proportion of the letters and numbers; enlarge the letters size; make the visual information more comprehensive determined by the reading field; put the expiry date in a better visual place

Os reguladores de crescimento podem retardar o desenvolvimento vegetativo das plantas de gramas e, assim, reduzir a frequência de cortes; contudo, existem poucas informações referentes aos efeitos desses produtos sobre as estruturas da anatomia foliar. Dessa forma, o presente trabalho teve por objetivo avaliar os efeitos da aplicação sequencial de duas doses de trinexapac-ethyl sobre a anatomia foliar das espécies de gramas São Carlos (Axonopus compressus), Batatais (Paspalum notatum), Santo Agostinho (Stenotaphrum secundatum) e Esmeralda (Zoysia japonica). Os tratamentos utilizados foram constituídos de duas aplicações sequenciais de trinexapac-ethyl nas doses de 56,5+56,5 e 113,0+113,0 g ha-1; além de uma testemunha sem aplicação, para cada espécie avaliada. Os gramados foram cortados à altura de 3 cm, com auxílio de um aparador de grama motorizado, e, em seguida, foram realizadas as aplicações dos tratamentos. Após 20 dias da primeira aplicação de trinexapac-ethyl, as parcelas foram novamente aparadas à altura de 3 cm e foi realizada a segunda aplicação dos tratamentos. O delineamento experimental utilizado foi o de blocos ao acaso, com quatro repetições. Aos 70 dias após a segunda aplicação dos tratamentos, foram realizadas as amostragens do material foliar, para as quatro espécies estudadas. Os dados das variáveis quantitativas foram submetidos ao teste estatístico multivariado de análise de componentes principais. Os resultados evidenciaram a formação de três e dois grupos principais, para os caracteres da região da quilha (nervura mediana) e da região da asa (situada entre a nervura mediana e a margem do limbo foliar), respectivamente. de modo geral, em cada formação dos agrupamentos, os tratamentos com trinexapac-ethyl apresentaram maior similaridade entre si, em relação às respectivas testemunhas. Conclui-se que a aplicação sequencial de trinexapac-ethyl alterou algumas estruturas anatômicas da região da quilha e da asa do limbo foliar das espécies de gramas estudadas.

This study is connected to the research line Poéticas da Modernidade e Pós -Modernidade, of the Programa de Pós-Graduação em Estudos da Linguagem, in the subarea: Comparative Literature - CCHLA/UFRN. Its main goal is to see fragmentation of writing as an aesthetic resource highlighted in the work of Tutaméia by Guimarães Rosa (1908-1967), and in Livro sobre nada by Manoel de Barros (1916). We undertake as a starting point the view that these works are allegorical expressions. We have as a basis the German philosopher Walter Benjamin (1984) conception about baroque allegory, that uses amorphous fragment and constitutes a dialectical expression, in which each person, each thing, each relation, may mean any other one (1984, p. 196). We see the stylistic features as used by Guimarães Rosa and by Manoel de Barros in the construction of poetics capable of breaking the boundaries between artistic genres, literary and discursive, adding oral, musical and plastic elements to writing. We also analyze the development of fragmentary poetics, in which the voice of the narrator/lyrical I, the characters, space, plot and time exhibit the fragment as a factor that contributes to the great ambiguity of the two works and to create a new language, performative and vibrant, rich in alluring images, allegories
