Alterações morfofisiológicas e moleculares em resposta a estresses abióticos em mamona (Ricinus communis L.)

The use of fossil fuels has been considered one of reason for the increase of pollution in the atmosphere and it may be related to the climate changes. Then, the research of the new sources of fuels will be important. Considering this, the use of biodiesel has been considered not as bad as petrol. The castor bean (Ricinus communis L.) is an important oilseed, which belongs to Euphorbiaceae family, and the oil found in the seed has important characteristics for biodiesel. This plant is considered as “rustic” as it does not need so much water for its development and oil production. Due to this, this plant has been considered to be ideal in semi-arid regions, such as the Northeast of Brazil. The aim of his study is to better understand the responses to abiotic stresses (drought and salinity) from castor bean plants using morphological, physiological and molecular tools. In order to do this, the castor bean plants were subjected to salt stress (50, 100, 150 and 200 mM NaCl) in a controlled environment and drought stress (5, 10, 15 days and 10 days cyclic). After these treatments, these plants were subjected to different analyzes: a) the expansion and retention of water from leaves; b) anatomy using leaves and roots. Based on these results, we found that castor suffered decrease in leaf area with increase drought stress, however restricted water loss, probably by accumulation of compatible solutes in the leaves. The anatomy data showed modifications in the vascular system. These modifications observed suggested that castor bean plant may be resistant to stress as it was verified in 5 days of drought as well as in 100 mM NaCl. In both conditions, these plants were fine. Probably these plants keep some solutes in the cell and then maintain the cell tugor. The data obtained in this study gave a better idea how castor bean plant responds to abiotic stress conditions - drought and salt stress

Abordagem da ergonomia para avaliação do treinamento simulado das equipes de resposta à emergência em lançamentos de veículos aeroespaciais

This dissertation introduces a study that aims to analyze the simulated training of emergency teams and proposes recommendations for the current training system in order to improve the collective skills and resilience of these teams when facing possible critical situations, triggered by possible accident occurrences during aerospace vehicle launching operations in the Barreira do Inferno Launch Center in Parnamirim / RN. This is a field, exploratory, descriptive, explanatory, and a case study with a qualitative approach. Therefore, we adopted the ergonomics approach, using the situated method of ergonomic work analysis (AET), combining observational and interactive methods. The relevance of this research is characterized by the contributions to minimize the human and material hazzards resulting from possible accidents in these operations, the scientific contribution of the AET for simulated emergency training analysis in the launching operations of aerospace vehicles - which are complex and involve risk of accidents - and consequently, the scientific contribution to the current process of recovering the Brazilian Space Program. The survey results point to problems of various kinds in the current simulated training system which compromise the safety of the operations. These problems are grouped into four categories: technological, organizational, team training and from the activity itself, regarding more specifically communication and cooperation (among the team members and these ones with other sectors involved in the launching operation) and regarding the coordination of actions. We propose: a) a new training model, from the creation and application of scenarios based on postulated abnormalities, which could simulate real critical situations, in order to train and improve the skills of the emergency response teams especially in terms of communication, coordination and cooperation; b) restructuring and reorganizing the current training system, based on the formal establishment of a managing staff, on the clear division of responsibilities, on the standardization of processes, on the production of management indicators, on the continuous monitoring, on the feedback from trainees about the quality of the training and on the continuing and frequent training of emergency teams.

A céu aberto: garimpando a memória e a identidade dos mineradores de Brejuí

The Brejuí Mine, situated in the municipality of Currais Novos (RN), was responsible for the local economy growth between the years of 1943 and 1990, causing the interest of miner's working class to its urban center. After the end of scheelita extraction, the mine became a "theme park", in 2004. The company left its mark on the city by building several monuments in reference to the mining activity and the company's founder, Tomaz Salustino. However, there are no written records that describe such activities on its early years, nor their pioneers in the mining subject. Therefore, it is important to investigate the miner’s memories and ask if, along the more than five decades that lasted the heyday of mining, an identity linked to the profession was built; the extent to which workers make reference to this history as membersand what are the symbols that are being triggered in the development of a working class identity. Further, I investigate what memory was mad concerning the pioneers, mostly farmers attracted by miner work. To do so, I make use of audiovisual archival resources and oral records of the interlocutors that were filmed in the preparations of the documentary “Lembranças de velhos garimpeiros". We have noticed that, in the script of the official history of the Brejuí Mine, the "boss" figure overlaps the workers and that the forms patronage, originated from the rural world, followed punctuating the social relations in the mine. Today, with the resumption of the mining activity, it is possible that the strengthening of the working class and the Seridó miner identity desire reborn.

Processos criativos com alunos-atores idosos: caminhos de uma dramaturgia de pertencimento

The present work is to present an experience artistic and pedagogical means of a laboratory-developed with senescent students from their memory files. Unlike other works developed with students of the third age, we make use of the archives of memory, where the drama takes from improvisations developed memories, in other words, the text is built not just recollected by students. Our work, however, is built by a look from the outside. The affective memories narrated by students serve as an engine for text construction and spectacle titled Vamos Falar de Amor. In this experiment the teacher-director also becomes an dramaturgista, and uses her imagination, that also comes filled with her own memories, in order to complete the gaps of the narrative, in a hybrid process in which the collective memory interlace the individual memory, transforming epic into dramatic. Here the route designed to get to the construction of the text and left the text for the second scripture, the spectacle. We want to show that old age is comprised of various hues, and that this phase of human development brings aspects that differ from old to old, and that education and theater can be a resumption of the social role of the elderly in contemporary surroundings. Therefore, the dramaturgy of memory creates the dramaturgy of belonging, facilitating in many aspects the Scenic Play with the elderly ones.

Análise da variabilidade climática sobre a produtividade da soja no município de Bom Jesus (PI)

The climate is still main responsible for the variations soybean productivity (Glycine max (L.) Merrill), exerting a limiting action on these agricultural systems. The bomjesuense cerrado, this culture has proved, over the years, an increase of cultivated areas, however, productivity does not keep the same pace, going through periods of oscillations. Thus, although the crop is added to high technology, culture has great vulnerability to climatic adversities. Thus, the present study aims to analyze possible trends in meteorological variables, which can influence the soybean yield in Bom Jesus. For this purpose, different datasets were used, as follows: i) two periods of daily data (1984-2014 and 1974-2014), both obtained from the National Meteorological Institute (INMET); ii) climate normals from 1961-1990 as defined by INMET; iii) local agricultural production data of soybean-year (1997/1998 to 2012/2013) obtained from the Municipal Agricultural Production (PAM) dataset, which is management by Brazilian Institute of Geography and Statistics (IBGE). The analysis procedures included calculations of climate normals for 1984 to 2014 period and some statistical applications, as follows: i) the Wilcoxon test, used to evaluate differences between climate normals (1961 to 1990 and 1984 to 2014); ii) the Mann-Kendall nonparametric test, in order to analyze the linear trend of agrometeorological variables (rainfall, maximum temperature, minimum temperature and diurnal range of temperature; iii) cluster analysis by Ward method and the Spearman correlation test (rs) to identify the relationship between agrometeorological variable and soybean annual productivity. We adopted a statistical significance level of 5%. The results indicate changes in seasonality of the 1984-2014 climatology with respect to past climatology for all variables analyzed, except for insolation and precipitation. However, the monthly analysis of precipitation indicate negative trend during October and positive trend in December, causing a delay in start of rainy season. If this trend is persistent this result must be considered in futures definitions of the soybean crop sowing date over the region studied. With Mann-Kendall test was possible to identify positive trends with statistical significance in maximum temperature for all month forming part of soybean cycle (from November to April), which in turn tends to cause adverse effects on crop physiology, and consequently impacts on the final yield. Was identified a significant positive correlation between soybean yield and precipitation observed in March, thus precipitation deficit in this month is harmful to the soybean crop development. No statistically significant correlation was identified among maximum temperature, minimum temperature, and DTR with annual soybean productivity due these range of meteorological variables are not limiting factors in the final soybean yield in Bom Jesus (PI). It is expected that this study will contribute to propose planning strategies considering the role of climate variability on soybean crop final yield.

Noção de simetria na cosmologia de Anaximandro de Mileto

Through the philosophical movements in Ionia and through researches made on phýsis (started by the first wise men in Miletus), we elected Anaximander‟s cosmology as a fertile ground for exploring the Greek notion of symmetry. From a geographical perspective, initially, the Greeks‟ originality towards the notion of a due measure will be questioned, since the astrological and mathematical knowledge were common in Babylon and Egypt. Although the cultural environment on the Milesian commercial ports and its architecture show evidences of a possible eastern impact on the Greek thought, it will be noted (from fragments validated by the Doxography tradition) that the problem with the birthplace of the notion of harmony and of due measure is something specific of the Greek culture and inherent to its remote religiosity. The resumption of these notions refers to the issue of arché and to its divinity assumed by Thales, Anaximander and Anaximenes. The divine was not an extrinsic notion to the Milesian thought towards the first element. Therefore, we will have as a result of this investigation some assumptions for which the notion of symmetry in Anaximander, stated in his ápeiron, could be, from the dialogue between philosophy and Orphism, an assimilation of the One, as witnessed in the Derveni papyrus.

“É acompanhante ou usuária?” Implicações sobre a posição da família no atendimento a crianças e adolescentes em um Centro de Atenção Psicossocial da Infância e Adolescência - CAPSi

This study emerged and founded itself with the aim to analyze the position taken by the family – and the implications in this subjective area – in attending children and adolescents in a Childhood Psychosocial Care Center (CAPSi). A secondary goal has come up as the comprehension surrounding the institutional representation made about the family and the service offered to children, adolescents and relatives. For such, the historical perspective on the relation between the State (laws and institutions) and the family was resumed, and the understanding of how it was reconciled by the medical knowledge and attended the ideological and political means. The social and ideological transformations of the 20th century culminated in the need of change required by the Psychiatric Reform and the achievement of patients on the right to return home and to their families. This new situation, permeated by the attempt of building an assistance model in Mental Health, presented a peculiarity–the close relationship between family and Mental Health services. The observations and conversations at CAPSi that were the investigation objects in this research, intended to learn on the quotidian of families and the possible treatment alternatives that would take into account the family circumstances. Conceiving the status of the families in Mental Health services is a germinal matter yet to be adjusted among the active knowledge in the post-Reform devices. The discussion about the family bonds, anchored in the theoretical perspective of Binding Psychoanalysis brought up elementary concepts such as psychic heritage, denial pact, unconscious alliances, the familiar psychic set, among other. The concept of family organizer helped to think of the family trajectories and stablishes a sort of identity for the family, as well as interferes in the establishment of its boundaries. The family path within the institution, as well as the status they establish facing the institutional approach, reflect the ghosts and the organizers shared by the group-family. It follows that the family is an important protagonist to be considered in the current therapeutic and political processes and, thus, is key to welcome the family bonds for the alliances act over the affective destinations, as well as try to remain sealed from the proposed changes.

Circuito regional de performance BodeArte: encontros, coletividade e porítica na performance do Rio Grande do Norte

This dissertation aims to look into the structure of the event Circuito Regional de Performance BodeArte1 to think how it collaborate with its proposal providing theoretical points to relevant questions to the comprehension of Brazilian performance art in contemporaneity, since its conceptual format until its occurrence and practical limitations. From this proposition the dissertation is organized into three chapters guided for the following aspects: the resumption of the events encompassed on the occurrence of Circuit BodeArte as well as a tabulation of the data reunited in its history, the presentation of its conceptual choices, and the metaphors conducted by the use of the term performance and how they can lead us to the idea of a performance-as-BodeArte. The methodological structures moved for this organization are qualitative, and have been formed from printed materials, texts, festival programs, blog, videos, photos, interviews, lectures and forums, plus our own memory as a producer and performer of the event, looking through these set points of the epistemological organization contained on the proposal of the Circuito, expanding and discussing them. This way this research moves between the propositions of this event in its three editions, promoting discussions that dialogue with concepts such as the emergence of Steve Johnson (2004), the metaphors of thought proposed by Christine Greiner (2005), the idea of performance hacker of Maria Beatriz de Medeiros (AQUINO, et al., 2012), as well as other propositions presented by Jan Swidzinski (2005) and Eleonora Fabião (2012)

Para transvalorar a dança contemporânea: potências de dança no (do) corpo-artista

Tanto no contexto acadêmico quanto no artístico e mercadológico, é crescente a discussão sobre o espaço de conceituação da dança contemporânea e suas fissuras, que deixam de abarcar esta ou aquela manifestação artística ou mesmo acaba por abarcar aquelas manifestações que não se encaixam em outros espaços de conceituação. No presente trabalho objetivamos a investigar, a Dança na Contemporaneidade, para além do que se entende por dança contemporânea, em sua capacidade de atravessar os espaços de conceituação já estabelecidos, para implicar em uma pluralidade de fazeres. Objetivamos também pensar a potência que a Dança imprime no corpo do artista criador, pensando também como este se comporta no espaço de entre linguagens . A dissertação que aqui se apresenta encontrou enquanto estratégia metodológica o recurso da metáfora, partindo das ideias de travessia, cartografia e cidades invisíveis para a construção do pensamento sobre o corpo do artista e suas relações com as diferentes linguagens artísticas, tomando por base uma retomada das experiências estéticas e artísticas de sua proponente. Dialogando experiências práticas e referenciais teóricos, inicialmente tratamos da dança contemporânea em seus problemas de classificação que apontam para a necessidade de um pensamento contemporâneo em dança, que pense as manifestações artísticas em seus pontos convergentes, e não nos divergentes que as situam sob diversas nomenclaturas. No capítulo seguinte discutimos a possibilidade de contaminação entre as linguagens artísticas a partir do próprio corpo-artista. Discorremos também sobre a dança enquanto agenciamento e resposta aos impulsos resultantes da relação com o espaço e outros corpos, pensando como o corpo do vivente se organiza nesta relação de compartilhamento de experiências. Mostrando uma potência do corpo artista criador que se dedica à transvaloração das fronteiras entre as linguagens para a organização do seu fazer. Por fim, apontamos para a diversidade na metodologia de processos de criação que variam de acordo com as possibilidades técnicas e necessidades estéticas de cada artista criador

Análise dos impactos do PAC sobre o crescimento do PIB a preços correntes

O Programa de Aceleração do Crescimento (PAC) abrange uma série de medidas de caráter econômico, e teve como finalidade promover a retomada dos investimentos em setores estratégicos da economia. Este trabalho teve como objetivo principal comparar um período sem o programa (1994-2006) com o período em que foi implantado o PAC (2007-2013). Assim, pode-se verificar que o crescimento da economia brasileira, medido através do Produto Interno Bruto (PIB) a preços correntes, foi influenciado pelos investimentos ocorridos através do programa, mesmo que esse intervalo seja marcado por uma grande crise, em 2008. Pois, como apontam os resultados obtidos desse estudo, no intervalo 2007-2013 as taxas médias de crescimento do PIB, Formação Bruta de Capital Fixo (FBCF) e Utilização da Capacidade Instalada (UCI) são maiores do que as do intervalo 1994- 2006.
