Gestión del riego en las llanuras argentinas. Poderes locales y provinciales en perspectiva comparada : Santiago del Estero y Buenos Aires entre la segunda mitad del siglo XIX y 1915

La vinculación productiva de los diferentes espacios agrícolas regionales argentinos al mercado mundial, durante la segunda mitad del siglo XIX, fue llevada adelante mediante diferentes políticas públicas en torno a la propiedad de los bienes, la gestión del territorio y los recursos. Y cada una de estas políticas impactaron en la relación entre las comunidades locales y los poderes provinciales. ;Con respecto a la gestión de los recursos hídricos, un tema aún poco abordado por la historiografía concentrada en las grandes llanuras, en este trabajo nos proponemos estudiar los modos en que fue cambiando el uso del agua para beneficiar a la agricultura en las provincias de Santiago del Estero y Buenos Aires, entre mediados de la década de 1870 y 1900. En la primera, estudiaremos la forma en que la cuenca del río Dulce se verá atravesada por canales principales que, tomando agua del curso principal, la derivarán a través de una red de canales subsidiarios e hijuelas, que trazaron una compleja red hídrica principalmente en el ejido urbano de la ciudad de Santiago del Estero para desarrollar cultivos novedosos para la provincia como la vid y la caña de azúcar, dando lugar a una serie de pequeñas villas. En la segunda observaremos cómo la demanda de grandes propietarios de las tierras de reciente ocupación criolla del suroeste provincial posibilitaba la construcción de canales de desvío de ríos y arroyos para regar sus campos, como así también la provincia desarrolló una serie de estudios de canalización para generar colonias agrícolas. ;Nos proponemos avanzar sobre las relaciones entre las tramas políticas y económicas y las confluencias de intereses públicos y particulares, que hicieron posible que los gobiernos provinciales tomaran bajo su responsabilidad la provisión de agua para el desarrollo de la agricultura; identificaremos las instituciones involucradas en el gerenciamiento del aprovisionamiento de agua y las cuestiones técnicas que se pusieron en juego, las dificultades que debían sortearse y los límites que planteaba el esquema de desarrollo. Por último, y teniendo en cuenta que para la administración del agua de riego el gobierno de Santiago del Estero organizó un esquema sindical centralizado con apoyaturas departamentales, nos adentraremos en la historia del primer espacio democratizador en la provincia con instituciones cuyas autoridades eran elegidas por los propios regantes propietarios de tierras y renovadas anualmente. Esto contrasta con el modelo bonaerense en el que la iniciativa privada de los grandes propietarios tuvo respuesta individuales a través de decretos y disposiciones ad hoc.

MANEJO TÉCNICO DO ATENDIMENTO PSICOLÓGICO EM AMBULATÓRIO DE REPRODUÇÃO HUMANA ASSISTIDA

O presente estudo teve por objetivos: descrever o manejo técnico do atendimento psicológico, ilustrado pelo caso de uma paciente infértil de um ambulatório de reprodução humana assistida; descrever as vicissitudes no campo analítico nestes atendimentos; e sistematizar esse manejo técnico em intervenções ambulatoriais em que se privilegia a compreensão das relações transferenciais. O instrumento utilizado para a coleta de dados foram os próprios atendimentos, ou entrevistas psicológicas, baseadas no método clínico de abordagem psicanalítica. A análise e a discussão dos resultados se basearam na apresentação de um único caso, que ilustrou a técnica que se objetivou sistematizar e descrever. É apresentado o caso da Sra. S., uma mulher de 41 anos, com parceiro em união estável há cinco anos, que realizava tratamento de infertilidade no ambulatório de reprodução humana. A paciente foi atendida pela psicóloga no próprio ambulatório durante o período da segunda tentativa de gravidez. Foram realizados efetivamente três (3) atendimentos e, no período de dois meses, a paciente não compareceu a três (3) sessões. Foram criadas cinco (5) categorias de análise: 1) Escuta; 2) Configuração de Queixa Psicológica; 3) Manejo dos Conflitos; 4) Manejo da Transferência; e 5) Enquadre. Estas categorias representaram elementos do atendimento. A divisão do atendimento em categorias teve propósito didático, no entanto, a sistematização do manejo deu-se a partir do desenvolvimento destas categorias, mas não numa ordem pré-estabelecida. A Escuta refere-se à capacidade do psicoterapeuta compreender a relação estabelecida com o paciente, assim como os elementos metapsicológicos depositados no campo, a partir de seu quadro de referência teórico-metodológico. A Configuração de Queixa Psicológica refere-se à aproximação do sofrimento psíquico e dos conflitos que subjazem à queixa orgânica ou manifesta. O Manejo dos Conflitos representa o modo como são interpretados e devolvidos a um paciente os conteúdos trazidos para a sessão. Ressalta-se, no manejo dos conflitos, a eleição de um foco de trabalho em que se privilegia a situação atual da vida do paciente relacionada especificamente à sua queixa. O Manejo da Transferência refere-se à forma como os aspectos transferenciais são compreendidos e devolvidos ao paciente. A neurose e psicose de transferência são evitadas e o trabalho é preferencialmente desenvolvido a partir da interpretação de situações extra-transferenciais. Por fim, o Enquadre engloba todos os aspectos formais e dinâmicos que constituem o campo emocional sobre o qual se trabalha. Este tipo de atendimento pode ser situado entre a entrevista psicológica e o atendimento em psicoterapia breve com objetivos e tempo limitados, variando de acordo com a qualidade adaptativa do paciente e sua motivação para o atendimento psicológico. Concluímos que este modelo de atendimento ambulatorial engloba aspectos tanto diagnósticos quanto de intervenção e que o papel do psicólogo neste contexto é auxiliar o paciente atendido a compreender sua queixa em seus aspectos latentes e manifestos, além de propiciar um espaço de escuta em que os conteúdos trazidos podem ser pensados e compreendidos

Extrafiscalidade: análise da norma potiguar regulamentadora do imposto sobre propriedade veicular automotora à luz da tutela ambiental

From the second half of the twentieth century the state bega n to use exaction beyond your fiscalist character, also as a means of alignment deformities economic and social balance, influencing in different directions, according to economic, social and political policy. It is what is usually called the extrafiscalit y. It is in light of this phenomenon and the constitutional perspective, the present work aims to analyze item IV of article. 8 of Law n. 6.967/96, regulatory Property Tax Vehicle Automotive (property taxes) in the State of Rio Grande do Norte, in view of its possible incompatibility with the principles of the Basic Statute and with international guidelines for protection of the environment The problem of this research is Seated in art. 225 of the Constitution, which provides that everyone has the right to an ecologically balanced environment. From the reading of this standard, extracted it is the responsibility of the state protecting the environment, which requires the adoption of suitable actions to that end. However, we look to state law cited follows th e constitutional path, since it exempts the collection of property taxes automotive vehicles with over 10 years of manufacturing, which could encourage the conservation of a fleet of old vehicles, mostly more polluting and harmful to the environment and hu man health. Would the state legislature oblivious to the constitutional principles and the global trend of environmental preservation? Thus questions whether such an incentive for more polluting vehicles, emitting more gases in the atmosphere. Moreover, th e international community is already moving through important conventions in an attempt to minimize and control global warming and climate change. Predicting the theme in CF/88 demonstrates that the country is no stranger to the issue. Thus, the work is a retelling of Law No. 6.967/96 order to check whether it is compatible with the existing system. The methodology consists of a documentary, deductive, dialectical literature. At the end of the survey, it was found that provide a tax benefit to these vehicle s is encouraged to maintain them in circulation and contribute to the increase in air and noise pollution, in addition to the traffic problems generated. Thus, this potiguar anything standard can be expressed extrafiscality because the medium and long term there is encouragement and worsening environmental problem. Despite the ability to pay clause, but this remission is an affront to legally protected interests. Thus, this device goes in reverse order compared to the values of the legal system and in relat ion to sustainable development. Modern Tax Law should be used as a tool to achieve the purposes collimated by the State, and not otherwise. It was noticed that the vast majority of Brazilian states does not follow this rule, including Mato Grosso and Minas Gerais have no such exemption. Therefore, the RN State does not constitute a model for sustainable public policies, nor example of environmental protection by state law.

Otimização da síntese do AlSBA-15 para produção de biodiesel por transesteri-ficação do óleo de coco

Stimulus encouraging the production and consumption of biodiesel favors the policy of pre-serving the environment, contributing to the reduction of greenhouse gas reducing climate change. The current trend of research in this field focuses on improving these processes with the use of heterogeneous catalysts, seeing has significant advantages such as: low contamination of products, ease of separation of the catalyst from the reaction medium, possibili-ty of reuse of the catalyst, decreased corrosion problems. The objective of this research was to optimize the synthesis of AlSBA-15 for the production of biodiesel through transesterification process via ethyl route. For the optimization of hydrothermal synthesis of type AlSBA-15 catalyst has assembled a 23 factorial experimental matrix with eleven trials. The stoichiometric amounts of starting materials were varied according to different ratios Si / Al which is a factor in the experimental design, in addition to the time and temperature of aging of the synthesis gel. The material showed the best results of characterization (SBET = 591.7 (m2 / g), Vp = 0.83 (cm3 / g), Dp = 5.59 (nm), w = 6.48 (nm) was synthesized at 100 ° C for 24 hours, with a ratio Si / Al = 10.This material was applied as a heterogeneous catalyst in the reaction of ethyl transesterification as raw coconut oil in natura. Coconut oil presented suitable for obtaining biodiesel via ethyl route.The visual aspects and physical-chemical characteristics of the reaction products show that AlSBA-15 catalyst favored the reaction. According to physical-chemical analysis the order of oxidative stability of the product of the transesterification reaction was: catalytic reaction at 1500 ° C> non-catalytic reaction at 100 ° C> 100 ° C catalytic> catalytic reaction at 200 ° C Reaction. The results of oxidative stability and kinematic viscosity shows that the biodiesel produced in the catalytic sandblasting held at 150 ° C which was maintained within the ABNT NBR 7148, ABNT NBR 10441 and EN 14112.

A evolução do turismo no Seridó: uma análise à luz do modelo de Butler

Tourism is configured as an activity that presents constant movement could boost local development in the economic, sociocultural and human in locations with potential for structuring and such. Because it is a dynamic activity, tourism allows changes in its flow, extending the periods of seasonality. To this end, in view of the aforementioned dynamics, it becomes relevant to the presence of tourism planning, initially starting from the government so that it create laws and standards and develop projects for the management of activities in an orderly way, seeking citizen participation, making essential the presence of actors and agents in local tourism, expanding democracy and knowledge of their place of origin. In this scenario, the Ministry of Tourism is emerging with the National Tourism Plan which incorporates among its actions, the Regionalization Program Guide, adopting a model of regional local management, a participatory manner, through the bodies of governance imposed at the poles, and the shares of public policy in their various departments most responsible for promoting tourism in pole Seridó. This scientific work aims to analyze the pole Seridó, under the theory of tourism area life cycle (TALC) proposed by BUTLER (1980), locating actions for tourism and chronology of the locality applied the proposed process activity. For both the methodology is descriptive and exploratory, qualitative approach, historical, descriptive and narrative level, non-probability sampling, using secondary sources, through documents and other records occurred during the planning processes in the region, in order to have access to information related to the planning process of tourism in Seridó, using as a way to research the data collected the technique of content analysis. As a conclusion of this study it is observed that from the survey in relation to the history of tourism in the region, economic activities of livestock, cotton industry, mining and ceramics industry were responsible for the initiation of tourism in the locality through the flow directed to the same, the insertion of the first hotels and performing traditional events, giving rise to the demand for public policies that aided in directing the activity being, therefore, inserted into the engagement phase, the second phase proposed by BUTLER (1980) model, and the study was terminated with suggestions for the continuation of tourism in the region.

Análise wavelet e modelo de manchas em curvas de luz estelares dos telescópios espaciais Kepler e CoRoT

Analogous to sunspots and solar photospheric faculae, which visibility is modulated by stellar rotation, stellar active regions consist of cool spots and bright faculae caused by the magnetic field of the star. Such starspots are now well established as major tracers used to estimate the stellar rotation period, but their dynamic behavior may also be used to analyze other relevant phenomena such as the presence of magnetic activity and its cycles. To calculate the stellar rotation period, identify the presence of active regions and investigate if the star exhibits or not differential rotation, we apply two methods: a wavelet analysis and a spot model. The wavelet procedure is also applied here to study pulsation in order to identify specific signatures of this particular stellar variability for different types of pulsating variable stars. The wavelet transform has been used as a powerful tool for treating several problems in astrophysics. In this work, we show that the time-frequency analysis of stellar light curves using the wavelet transform is a practical tool for identifying rotation, magnetic activity, and pulsation signatures. We present the wavelet spectral composition and multiscale variations of the time series for four classes of stars: targets dominated by magnetic activity, stars with transiting planets, those with binary transits, and pulsating stars. We applied the Morlet wavelet (6th order), which offers high time and frequency resolution. By applying the wavelet transform to the signal, we obtain the wavelet local and global power spectra. The first is interpreted as energy distribution of the signal in time-frequency space, and the second is obtained by time integration of the local map. Since the wavelet transform is a useful mathematical tool for nonstationary signals, this technique applied to Kepler and CoRoT light curves allows us to clearly identify particular signatures for different phenomena. In particular, patterns were identified for the temporal evolution of the rotation period and other periodicity due to active regions affecting these light curves. In addition, a beat-pattern vii signature in the local wavelet map of pulsating stars over the entire time span was also detected. The second method is based on starspots detection during transits of an extrasolar planet orbiting its host star. As a planet eclipses its parent star, we can detect physical phenomena on the surface of the star. If a dark spot on the disk of the star is partially or totally eclipsed, the integrated stellar luminosity will increase slightly. By analyzing the transit light curve it is possible to infer the physical properties of starspots, such as size, intensity, position and temperature. By detecting the same spot on consecutive transits, it is possible to obtain additional information such as the stellar rotation period in the planetary transit latitude, differential rotation, and magnetic activity cycles. Transit observations of CoRoT-18 and Kepler-17 were used to implement this model.

Análise da influência do efeito esteira de aerogeradores no microclima na superfície do solo: o caso do parque eólico piloto de Macau/RN

This study aimed to evaluate the microclimate changes surrounding the wind farm Macau Pilot / RN, present in the municipality of the same name. To achieve this goal made use of remote sensing techniques using Landsat - 5 TM and 7 ETM +, from which made it possible evaluation of temperature changes on the surface, this around the park in periods prior to its implementation, to the today. For evaluation of the temperature data that has been generated by applying a template was performed its correlation with field data collection and evaluated the degree of correlation, in order to confirm the validity of the data acquired by satellite. Also held was a characterization of the climate of the region based on the data of this climatological station in Macau. Once collected this data made possible the evaluation of climate change policy in the study region. After validation of the temperature models, an analysis of the generated temperature histograms was performed visually could not identify any significant change. However when analyzing the temperature data at a higher level of detail, a data pattern of behavior was detected for both periods evaluated, yet could not see a distinction between the periods of pre-operation of the park, and post-operation . From this result was levantas hypotheses to explain the behavior of the data, the first of which is the presence of moisture in the soil, and the second to the soil composition. In order to validate the hypotheses were applied PDI techniques, involving a combination of different RGB bands of Landsat 5 and the implementation of Reason bands procedure that might show the elements present on the soil surface.

Petrologia e geologia estrutural do plutão granítico Barcelona, província Borborema, NE do Brasil

The Dissertation aimed to advance the geological knowledge of the Barcelona Granitic Pluton (BGP). This body is located in the eastern portion of the Rio Grande do Norte Domain (RND), within the São José do Campestre subdomain (SJC), NE of the Borborema Province. The main goal was to understand the geological evolution of the rocks of the pluton and the tectonic setting of magma generation and its emplacement. The BGP has an assumed Ediacaran age and outcropping area of approximately 260 km2, being composed of three varied petrographic/textural facies: (a) porphyritic biotite monzogranite; (b) dykes and sheets of biotite microgranite; (c) dioritic to quartz-dioritic enclaves. The rocks of the BGP have the following structures: (i) a NE-SW and NW-SE directed magmatic fabric (Sγ), accompanied by a magmatic lineation (Lγ) with gentle dip to NE-SW and NW-SE. In the southern portion, there is the concentric pattern of this foliation with medium to high dip, and (ii) a solid state foliation, in part mylonitic (S3+), mainly on the eastern edge with slightly plunging to west. The integration of structural and gravity data permitted to interpret the emplacement of the BGP as controlled by the transcurrent shear zones systems Lajes Pintadas (LPSZ) and Sítio Novo (SNSZ), both of dextral strike-slip kinematics. Mineral chemistry data show that the amphibole form the porphyritic biotite monzogranite facies is hastingsite with moderate Mg / (Mg + Fe) ratios, indicating crystallization under moderate to high ƒO2 and cristallization pressure of around 5.0-6.0 kbar. The biotite tends to be slightly richer in annite molecule and plots in the transitional field from primary biotite to reequilibrated biotite. In discriminant diagrams of magmatic series, the biotite behave like those of subalkaline affinity, consistent with the potassium calc-alkaline / sub-alkaline geochemical affinity of the hosting rock. The opaque minerals are primarily magnetite, with some crystals martitized to hematite indicating relatively oxidizing conditions during magma evolution that originated the BGP. Zoning in plagioclase, K-feldspar and allanite crystals suggest fractional crystallization process. Lithogeochemical data suggest that the facies described for the BGP have similar magma source, usually plotting in the fields and trends of the subalkaline / high potassium calc-alkaline series.

Utilização de sismos regionais para a determinação de um modelo 1D de velocidades da onda P na Província Borborema - NE do Brasil

In this work it was performed a study to obtain parameters for an 1D regional velocity model for the Borborema Province, NE Brazil. It was used earthquakes occurred between 2001 and 2013 with magnitude greater than 2.9 mb either from epicentres determined from local seismic networks or by back azimuth determination, when possible. We chose seven events which occurred in the main seismic areas in the Borborema Province. The selected events were recorded in up to 74 seismic stations from the following networks: RSISNE, INCT-ET, João Câmara – RN, São Rafael – RN, Caruaru - PE, São Caetano - PE, Castanhão - CE, Santana do Acarau - CE, Taipu – RN e Sobral – CE, and the RCBR (IRIS/USGS—GSN). For the determination of the model parameters were inverted via a travel-time table and its fit. These model parameters were compared with other known model (global and regional) and have improved the epicentral determination. This final set of parameters model, we called MBB is laterally homogeneous with an upper crust at 11,45 km depth and total crustal thickness of 33,9 km. The P-wave velocity in the upper crust was estimated at 6.0 km/s and 6.64 km/s for it lower part. The P-wave velocity in the upper mantle we estimated at 8.21 km/s with an VP/VS ratio of approximately 1.74.

A escrita da escrita em (d)enunciação no espaço sócio-escolar: um espaço (em vão) para a (cri)atividade escrita

This thesis is a writing of (d)enunciation because it reveals the language experiencies of those individuals who take, in social school space, the social role of the teacher and of the student, for some reason, they feel restrained by a demand which prevents them of teaching and learning how to write – and, even, their own writing. On this basis, we consider some questions concerning Benveniste‘s theory of enunciation and the teaching and learning process in Portuguese from the triad among teacher – teaching of writing/ knowledge – student, making this theoretical area closer to the pedagogical one. We support in the working hypothesis that is based on the position of the loosening of this triad has its effects in the process of intervention-interference to the point where it does not leave a scar which can remain working on productive effects on the student‘s writing. As a consequence, we show two findings which allow us to think the teaching of writing in Portuguese is a space for writing creativity in such a way it reveals itself as a sine qua non condition for the institutionalized and subjective writing. The first finding is that taking genre as a model has some implications in the teaching and learning process of writing according to the instructions of the official documents. The second finding, as a result of the first one, is the assumption that genre is at the same time a model and a transgression and taking it as a (ex)sample opens space for writing creativity which ―is a transposition of the interior language‖ (BENVENISTE, 2014 [1968-1969], p. 132) in a way this creativity makes it intelligible and highlights what is a model (interactiveness) and a transgression (inventiveness). From such findings, we organize our heterogeneous corpus according to these procedures: recording the classes in audio; recording the interviews we made with teachers and students in audio; and constituting an archive with the students‘ writing production. From this corpus, we analyzed the (d)enunciative mo(ve)ments in the teacher – teaching of writing/ knowledge – student triad and the history of (d)enunciations, of language experiences. Besides, we analyzed the teacher‘s discourse in relation to the way he plans his classes based on the knowledge that must be taught and his own way of managing this knowledge in order to understand his interference in his students‘ writings. Our analyses (re)affirm that when the loosening of the triad happens, the students become lost, what makes them unable of working upon their own writing epilinguisticaly. Because of it, schools have lost their specificity as a place for teaching students how to read and write as they open space for training, only. On this basis, we consider that the effect of such a loosening generates complaints and denunciations. Therefore, based on such (d)enunciations, we present the Primary sketches of a proposition for intervention-interference in teaching how to write and we aim at introducing much knowledge to teachers and students in order to allow them to think about possible ways out.

Validez de un modelo reducido de items del DSM-IV según respuesta de padres y profesores en el diagnóstico del Trastorno por Déficit de Atención con Hiperactividad Combinado

El objetivo es buscar un modelo reducido de síntomas del Trastorno por Déficit de Atención con Hiperactividad subtipo Combinado (TDAH-C), que presente adecuada validez de criterio para su diagnóstico. La metodología se basa en contexto de estudio epidemiológico. Muestra de 1095 casos entre 6 y 16 años [4.38 % TDAH-C]. Se realiza una selección de casos con primera fase psicométrica de sospecha TDAH-C que requiere que ADHD RS-IV, implementado por padres (PA) y profesores (PR), supere el PC 90. En la segunda fase, los casos seleccionados se evalúan mediante entrevista clínica modelo DISC-IV (DSM-IV) para confirmar TDAH-C. Se implementa regresión logística para buscar modelo parsimonioso de ítems que permita predecir TDAH-C. El modelo de ítems que permite predecir TDAH-C contiene 8 de los 36 ítems del ADHD RS-IV contestados por PA y PR. Considerando las odds ratio del modelo de regresión logística, los ítems del ADHD RS-IV seleccionados son los siguientes 15PR, 1PA, 16PR, 12PA, 17PA, 10PA, 14PA y 4PR. El modelo presenta validez de criterio para TDAH-C clínico (sensibilidad: 97.9 %. Especificidad: 93.8%. Razón de verosimilitud: 16.02). Es posible reducir la lista de síntomas de TDAH-C con buena validez de criterio, manteniendo los que proporcionan mayor discriminación entre TDAH-C y población general.

Modelo de decisão multicritério para seleções interciclo das universidades novas: estudo na Universidade Federal do Rio Grande do Norte

The discussions wherein develop proposals for university reform in Brazil include, among other things, the conception of the university titled "New University", whose structural origin comes from the bill of higher education reform and unification of the foundations of education European upper (Bologna process). At its core, the Bologna process has imposed a series of transformations, among which, the promotion of mobility, as a stimulus to interinstitutional cooperation to enable an better and bigger qualification of the students. Nevertheless, what we see is that this point is one of the main points made flawed by Brazilian institutions that have adopted this model of higher education. An example is the Bachelor of Science and Technology - BC&T, Federal University of Rio Grande do Norte - UFRN, where there are problems of the internal order, represented by the problem of the reusing of the disciplines, such also of external order, in cases of transfers interinstitutional. Because of this, and knowing that this is a typical problem in which multiple criteria are involved, the aim of this study is to propose a multicriteria model for selection of interciclo of the BC&T of the UFRN which addresses the issue of mobility. For this, this study was of exploratory and study case nature, use as tools of data collection, the bibliographic and documentary research, as well as semi-structured interviews. For the elaboration of the model, were used the five phases most commonly used in the modeling of problems in operational research in a sample of 91 students of BC&T. As a result, we obtained a model that addresses the issue of internal and external mobility of the school and that, moreover, was also more robust and fair than the current model of BC&T and also what is used in other courses of the UFRN, taking into consideration the expected results by the decision makers
