Preliminary studies on reservoir Itupararanga indicate that the seasonal dynamics of plankton community is not being strongly controlled by bottom-up forces. Cianobactéria Cylindrospermopsis raciborskii and clorofícea Monoraphidium contortum are the dominant phytoplankton species in this reservoir. Bosmina freyi, recently described, is the dominant zooplankton in Itupararanga and there is no records of studies feeding habits of this specie. Therefore, the present study aims to assess the importance of the cladoceran Bosmina freyi as consumers of phytoplankton species: Monoraphidium contortum and Cylindrospermopsis raciborkii to better understand the ecological role of this organism in the planktonic food web in reservoir Itupararanga. M. contortum and three types of strain C.raciborskii, toxic strain (Cy.tox), strain with large filaments (Cy.grd) and strain with small filaments (Cy.peq) where ofered for Bosmina freyi. For each treatment, were calculated the density, cell volume, biovolume before and after incubation with B. freyi.Also calculated the ingestion and filtration rates. Qualitative models have also been made to describe and make predictions on the plankton community Itupararanga when there are changes in the population of Chaoborus sp. It was noted that B. freyi is able to efficiently ingest C.raciborskii including toxic strain, but presented difficulties in filter and ingest filaments of Cy.grd.Besides, B.freyi seems to be able to cut up filaments of C.raciborskii for ingestion. No food preference was observed by M.contortum. Qualitative models made in this study corroborate the hypothesis that seasonal variations in plankton reservoir Itupararanga may be being controlled by top-down forces due the presence of Chaoborus sp.

Cancer, is the name given to a set of more than 100 diseases that have in common the uncontrolled growth of cells that invade tissues and organs. It is occurs for several reasons, among them changes in DNA that may be caused by many factors such as oxidative stress, exposure to sunlight and smoking. Many efforts are being made in the search for treatments that may prolong a patient's life or even cure of the disease. In this quest, many chemotherapeutic compounds have been developed in an attempt to combat the different types of cancer. Among these various compounds were developed directly or indirectly from natural products derived from plants or bioactive compounds such as camptothecin, extracted from the bark of Camptotheca acuminata plant and taxol derivative of Taxus brevifolia. Flavonoids are a group of secondary metabolites, which belong to the class of polyphenols. They are found in several species of plants, especially in fruits, seeds and flowers. Many of them were described as having high antioxidant, anti-inflammatory, antiallergic, hepatoprotective and antitumor capacity. The main groups are derived from flavonoids are: flavanols, flavonols, isoflavones, anthocyanidins, flavonones, and flavones. The naringenin belongs to the group of flavonones commonly found in citrus fruits and has shown in previous studies to possess anti-tumor action. To make more effective the action of these compounds, many have been linked to metal complexes which increases the cytotoxicity of the same. One of the biggest challenges in the field of cancer research is to obtain a chemotherapeutic compound that is cytotoxic to tumor cells only and has fewer side effects compared to drugs currently used. Thus, the aim of this study was to evaluate and compare the cytotoxic effect of naringenin and naringenin complexed with copper and 2,2 '-bipyridine, in triple-negative breast cancer cell line, MDA-MB-231 and understand some of the mechanisms molecular action involved.

Neuropathic pain is a type of chronic pain that can causes comorbidities such as generalized anxiety and depression, and, consequently, it produces considerable damage to the quality of life of affected people. Despite it being refractory to most conventional pharmacological treatments, studies evidence that serotonergic drugs, like antidepressants, are effective in treatment of this type of pain. Serotonin is a neurotransmitter with an important role in the modulation of nociceptive stimuli as well as the behaviors related to fear and anxiety. There is evidence that aversive situations, such as predator exposure may cause antinociception as a defensive reaction. Thus, several studies have demonstrated that fear or anxiety stimulus can cause antinociception and the serotonin (5-HT) produces this antinociceptive effect in structures of the central nervous system, such as the periaqueductal gray matter (PAG). In this sense, studies from our group demonstrate that activation of 5-HT2C receptors in PAG is involved in anxiolytic effects and in fear and anxiety-induced antinociception in mice exposed to the elevated plus maze. However, it is unknown what the role of PAG serotonergic receptors in the modulation of antinociception induced by exposure to predator (rat). Thus, the objective of this study was to evaluate the effect of activation of 5-HT2C receptors of PAG on the antinociception and defensive behaviors in mice submitted to sciatic nerve constriction. For this, Swiss-albino male mice were submitted to sciatic nerve constriction on the first day of the experiment and, seven days later, they received implantation of guide cannula in the PAG. Four days after stereotactic surgery, mice received intra-PAG injection of vehicle or mK212 and were exposed to the predator. The test consisted of two phases: a) habituation to the apparatus for 10 minutes for 3 consecutive days, which started the next day after stereotactic surgery; b) exposure to predators or neutral stimulus for 10 minutes. The analysis of variance (ANOVA) of three factors (condition x stimulation x treatment) showed that chronic constrition injured (CCI) mice exhibited increased of scratching behavior, that is indicative of chronic pain. The exposure of these animals to the predator (rat) produced antinociception in CCI mice and increased behaviors related to fear and anxiety such as time spent in protected area and total number of stretched attend posture (SAP) and decreased time of contact with the grid, when compared to mice exposed to neutral stimulus (toy rat). Treatment with mK212 intra-PAG (0.21 and 0.63 nmol) produced no significant change in antinociception and fear and anxiety assessed during exposure to rat. However, the mK212 0.21nmol dose treatment increased scratching behavior, indicating hyperalgesia in CCI mice exposed to toy rat. Thus, we suggest that 5-HT2C receptors of PAG appear to modulate differently this type of antinociception and fear and anxiety in mice. However, further studies should be conducted using more selective subtypes of serotonergic receptors and perhaps other models of nociception to enlarge and clarify the role of 5-HT2C receptors in the processes that modulate antinociception induced by aversive stimuli.

Frameworks are software artifacts that implement the basic functionality of a domain. Its reuse can improve the efficiency of development process and the quality of application code. However, frameworks are difficult to develop and reuse, since they require a complex structure to implement domain variability and be adaptable enough to be reused by different applications. Due to these difficulties, this research presents two approaches: 1) the From Features to Frameworks (F3) approach, in which the developer models the features of a domain and a pattern language helps in implementing a framework based on this model; and 2) the approach that uses a Domain-Specific Language (DSL) built from the identification and analysis of the domain features of a framework to facilitate the reuse of this framework. A tool, called From Features to Frameworks Tool (F3T), was also developed to support the use of these two approaches, providing editors for modeling domains and applications and automating the implementation of code of frameworks, DSLs and applications. In addition to facilitate the development and reuse of frameworks, experiments conducted during this project showed that these two approaches make these processes more efficient and allow the construction of frameworks and applications with less difficulty.

This work presents ethnographic research concerning recent initiatives of cultural revitalization in the Alto Rio Negro region, particularly those initiatives that have been taken by tukano speaking groups in the Uaupés river basin. Therefore, this study is a combination of short-term field work and bibliographic research. The case under analysis is that of the recent repatriation of a set of ceremonial ornaments (basá basá), which had been kept for decades at the Museu do Índio in the city of Manaus. Considering the impossibility of defining the communities to which these pieces had originally belonged, it was decided that the repatriated ornaments would become the collective property of the indigenous peoples of the Uaupés river basin, in custody of an indigenous organization pertaining to the multiethnic group of Iauaretê. This research showed that the ornaments are considered to be people with agency, in such a way that concerns relating to the appropriate uses and circulation of these objects arouse anxiety as to the misfortunes that such objects could bring about to those who used or manipulated them. However, some people from Iauarete affirmed that the ornaments could not only be tamed and revitalized, but also transmit important knowledge to those who used them.

Empathy can be defined as the capacity for perceive emotional signals from others. Among these signals, the ability to perceive pain has clear adaptive and evolutionary value. Pain can be defined as a subjective experience that includes sensorial, emotional and cognitive components. Evidence has emphasized the role of amygdala, anterior cingulate cortex (ACC) and insula in modulation of pain and empathy. Research indicates the capacity of rodents to express empathy to a conspecific in pain or suffering. Works from literature and finds from our laboratory demonstrated that living together with a cagemate is able to alter the nociceptive behavior in mice. However, there are no works evidencing if occur alterations in nociception by living together with a cagemate with chronic pain and which encephalic structures would be involved in this modulation. To overcome this, male Swiss-albino mice were housed in groups or in pairs. The role of amygdala, ACC and insula are accessed by non-selective inactivation with cobalt chloride (CoCl2). Mice housed in groups (Experiment 1), aging 6-8 weeks, underwent a stereotaxic surgery. 4 to 5 days after surgery, these animals received saline or CoCl2 microinjection, and, after 10 minutes, they were submitted to the writhing test during 5 minutes (acetic acid 0.6%, i.p., nociceptive stimulus). On the dyads (Experiment 2), animals lived together for 28 days since weaning. On the 14th day, one animal of each pair were submitted to a sciatic nerve constriction (SNC animal) or not (sham animal). On the 24th day, the cagemate underwent a stereotaxic surgery, and, on the 28th day, they were submitted to the writhing test after microinjection of saline or CoCl2, like the procedure described to Experiment 1. To Experiment 1 were utilized Student s t test to independent samples; to Experiment 2 were utilized two-way analysis of variance (ANOVA; living together x treatment). Duncan s multiple range tests were utilized as post hoc. A p value of 0.05 or less was required for significance in both experiments. In Experiment 1, inactivation of the amygdala increased the number of writhing, while inactivation of ACC and insula did not alter this measure, suggesting a distinct modulatory role of these structures on the sensorial compound of pain. Our results demonstrated that for the mice that lived in groups, while inactivation of the ACC and insula did not change writhing, inactivation of amygdala increased it, suggesting a distinct modulatory role of these structures on sensory component of pain in the writhing test. In Experiment 2, living together with a SNC-cagemate increased writhing on the pair, suggesting that this experience activates the circuitry of neural representation of pain on the observer mouse (state of priming ). Thus, when this animal experienced nociception, its response was exacerbated. In this condition, inactivation of insula and amygdala produces opposite results, i.e., decreased and increased in contortions in those animals that lived together with a SNC animal, respectively. ACC inactivation did not alter writhing behavior. In this sense, our results suggest a different modulatory role of these structures on cognitive, affective-emotional and sensorial components of pain, and on empathy for pain.

This study reports on the information obtained by analyzing actual urban bicyclecommuter routes in São Carlos, using Global Positioning Systems (GPSs) for collecting the data and a Geographic Information System (GIS) for analyzing the data. The characteristics of the routes used by cyclists were compared with the characteristics of the shortest-path routes. The extra distance travelled was computed by the difference between these two lengths, and a multiple linear regression was created for explain the reason for this extra distance. The results showed that 70% of the trips were, at most, 15% longer than the shortest path, the average extra distance was 220 meters and the factors that have an influence was the street hierarchy and pavement quality.

The present study aimed to analyze how an education that prioritizes tasks of exploratory- investigative nature can contribute to the generation and/or mobilization of geometric concepts in the 7th grade students of elementary school. More specifically, the tasks contained in this dissertation fieldwork, contemplated the learning of geometrical concepts involved in the composition of mosaics with regular polygons. The investigation of a qualitative nature, in the form of case study occurred in a public school in the town of Pilar do Sul, the state of São Paulo, where the information was produced and collected between the first and the second semester of 2013. The technique of triangulation of data involved audio, video and photographs records, students written records and observation notes of the participant teacher - researcher. To describe and analyze the process of students learning we support in Ponte (2009 ) and his various studies on exploratory and investigative tasks, in Fischbein (1993 ) with the theory of figural concepts and Tall (1995); who studied the phases of human activity and mathematical reasoning. The survey results allowed to identify the students progress and difficulties to explore the tasks over time they were performed. With the experiences, the students began to develop clearer written records and used a mathematical language with greater mastery of mathematical terms, in particular the geometry. Furthermore, they demonstrated appropriating and/or expand figural concepts like angles, straight, regular polygons and mobilized such knowledge during the exploration of the properties and relations of these objects.

Objective: This thesis investigated the effect of a few minutes of reaching practice under different practice schedules on the reaching behavior of late preterm infants at the onset of goal-directed reaching. Method: This is a blind, three-arm parallel-group, randomized controlled trial. Thirty six late preterm infants (16,7 ± 2,3 weeks, chronological age) were allocated into groups that received reaching practice based on either a blocked schedule, a serial schedule, or no practice. The infants were assessed 3.3 ± 1.4 days after the onset of goal-directed reaching in three tests: pre-test (immediately before practice), post-test (immediately after practice), and retention test (24 h after post-test). Practice was applied between the pre- and the post-test (intrasession) and consisted of a 4 min. session of induced reaching using a toy in three activities guided by a physical therapist. The activities were elicited in separate blocks for the blocked practice group and in a serial order for the serial practice group. The control group stayed in the physical therapist s lap and was not stimulated to reach. During assessments, the infants were seated in a baby chair reclined 45º from the horizontal axis. A toy was presented at his/her midline within reaching distance for 2 min. The assessments were filmed and the images analyzed considering the following variables: number of reaches, proportions of proximal adjustments (uni and bimanual), distal adjustments (hand opening) and grasping outcome (reaches with and without grasping), and kinematic variables (straightness index, deceleration index, movement units, and velocity). Results: The major findings were increased amount of reaches from pre- to post-test for the serial practice group (p < 0.01). At the pre-test, the serial practice group performed unimanual reaches only; at the post-test, those infants increased the proportion of bimanual reaches compared to the pre-test (p = 0.05). There were no diferences between groups. Conclusions: Serial practice schedule may have required less perceptive and motor demands from the late preterm infants. The toyoriented experience, which stimulated the infants to perceive and act upon the toy successfully in a serial practice schedule, may have favored the infants perceptionaction coupling. This may have provided them with new oportunities to explore strategies to potentialize the transport of the hand towards the toy. Such stimuli were enough to lead to immediate, temporary adaptative changes.

The electrodeposition of Cu-Sn-Zn ternary alloys onto AISI 1010 steel from an acid bath with EDTA or NTA salts was investigated, with various proportions of the metal ions in the baths. The concentration of these metals in the baths was determined by factorial design of mixtures with pseudocomponents. From potentiometric titration of these baths were determined regression equations, which led to studies of variance analysis and of surface response. These studies allowed to a pH of stabilization of the Cu-Sn-Zn electrodeposition baths. The Cu-Sn-Zn voltammetric profile showed five cathodic regions: c1, c1 , c2, c3 and c4 (depending on bath composition), and the conditional potentials for the Cu2+, Sn2+ and Zn2+ complexes indicated that these regions were associated, respectively, with reduction of [CuY]2- complex to Cu; [Sn(H2O)6]2+ complex to Sn; [SnY]2- complex to Sn; H2O to H2; and [ZnY]2- complex to Zn. In the presence of NTA, [Cu(NTA)2]4- and [SnNTA]-, [Sn(NTA)2]4-; H2O and [ZnNTA]- and [Zn(NTA)2]4-, respectively, in the regions c1, c2, c3 and c4. Cu-Sn-Zn electrodeposits produced at Ed 1.70 V with qd 3.0 C cm−2 were characterized by EDS, SEM, XRD and confocal optical microscopy (COM) analysis. EDS indicated that a transition potential exists wherein a transition from Cu-Sn binary alloy to Cu-Sn-Zn ternary alloy occurred and, also, that Cu-Sn-Zn co-deposition was normal, preferential or anomalous depending on the bath composition. Moreover, this analyze showed that Zn reduction was facilitated in the presence of NTA. SEM of electrodeposits showed that they were formed by globular and/or irregular crystallites, and, in general, by clusters of crystallites of different sizes dispersed on this layer, depending on the bath composition. COM analysis showed that electrodeposit produced from NTA was more roughness than with EDTA. XRD pattern indicated that the Cu-Sn-Zn electrodeposits, depending on the composition of the baths, presented low crystallinity or crystalline structure with mixture of SnO, η- Cu6Sn5 and Cu5Zn8 phases or pure Sn, η-Cu6Sn5 and Cu5Zn8 phases. Multivariate analysis allows extracting the maximum relevant chemical information from the data.

The problem articulated in this work is to understand how the mato-grossense poet Manoel de Barros has been produced a modern poetry since the start of his career, when he had published the books Poemas concebidos sem pecado (1937) e Face imóvel (1942). To identify such a question, it will support, first in an overview of the barreano themes and stile, following, it will be done interpretative analysis of some poems from both books, in order to see if the modern aspects presented as marks on his poetry have already appeared since the beginning of his writings and if changes occurred in these traits throughout his literary creations. Thus, this research will verify the guiding-up elements of his first poetry, in order to establish relations between his initial poetic project and the rest of his works. This interpretative and comparative approach will contribute to the understanding and affinities of his unconventional lyrical. As it was seen here, both the recurrence of certain themes and some peculiarities of barreano style, it can show various signs of modernity which, in turn, helped to single out his poetics.

The synthesis and characterization of five ruthenium (III) complexes such as mer-[RuCl3(dppb)(N)], where N = pyridine and 4-substituted derivatives were performed in this work. These complexes were evaluated as catalysts in hydrogenation reactions of cyclohexene and some aldehydes. The obtained results were very satisfactory, presenting values higher than 80% of conversion, in 15 h. These ruthenium (III) complexes, two ruthenium (II) complexes containing CO as ligand and other four precursors, were also tested as catalysts in hydroformylation reactions of alkenes. Considering that is known that hydroformylation reactions can form several sub products, in the best reaction conditions, these catalysts were able to produce up to 61% of product, with only 14% of one sub product. These results were considered satisfactory, due to the possibility to work without additives, promoting a "green" reaction. The ruthenium (III) precursor mer-[RuCl3(dppb)(H2O)], was supported in three different polymers (poly-4-vinylpyridina P4VP, chitosan QT e aminopropyl silica APS). The catalytic activities of these polymersupported compounds were tested in hydrogenation of cyclohexene. Due to the possibility to separate the solid catalyst by filtration and easily isolate the product, the results showing 70% of conversion were considered satisfactory and "green". The ruthenium complex chitosan-supported was tested on the formation of a film, which was used to modify a glassy carbon electrode (GCE). This modified GCE was tested as an electrochemical sensor for the detection and quantification of drugs (acetaminophen and sildenafil citrate). The electrode showed a great electrochemical response and high sensitivity when compared to an unmodified glassy carbon electrode and a glassy carbon electrode chitosan modified. The polymeric film was stable to degradation in acids electrolytes showing a linear response evaluated in 1,25 x 10-5 a 4,99 x 10-4 mol L-1 concentration interval.

The demand for air travel has grown each year, both in Brazil and abroad. Researches also indicate an estimated worldwide increase in elderly and obese people. In regards to people with disabilities, studies show that approximately 15% of the world population has some kind of disability and only in Brazil it´s believed that this population represents 25%. There is a growing participation of people with disabilities and people with special needs (such as the elderly and obese) in society, including the use of air transport. These people take use of assistive equipment (assistive technology) in their daily lives, and how air passengers, they take these products on board. That´s the focus of this study: a study in assistive technology. Thus, the goal is to identify products of assistive technology and understand the trends in this field to support future discussions about the implications for aircraft cabin design. First, a literature review was performed in order to better understand assistive technology and universal design. Then, collecting data through research at fairs, internet, survey and interviews related to assistive technology companies was performed. Such procedures indicated what kind of assistive technology products are used and what the emerging products are. Data were collected and analyzed from a descriptive perspective. The conclusions of the study were then formulated. They indicate a large number of assistive technology products for people with physical and visual disabilities and a big trend in multifunctional and electronic products. Assistive technology products bring great impact to the current and future design of the passenger cabin.

This research introduces the use of digital human modeling packages Tecnomatic members (Simens) - Jack software - and Dassout System - Delmia software. This choice is justified by the representation of these packages in terms of industrial applications as well as by the availability of such PSPLab / DEP / UFSCar. The overall study aims: to assess the variability in responses between the results of both software and application of RULA, NIOSH and Snook and Ciriello tools in real environment. And as a specific goal: to characterize the application of these tools in both softwares and compare the performance of different softwares. While search procedures were selected common three softwares analysis tools (RULA, NIOSH and Snook and Ciriello) and applied the same work situations. As base of applications and modeling in software performed the procedures prescribed for application of the tools were made by the researcher. Thus, the same situation was analyzed in three contexts: application of the tool by the researcher in a real environment (P), in Delmia (D) and in Jack (J). The activities were selected according to what each tool aims to analyze. It was observed that the results of the RULA and Snook and Ciriello real environment and digital applications have been coming, since the results of the NIOSH applications in both environments were discrepant . It is concluded that the RULA and Snook and Ciriello tools can be applied in human simulations in softwares Delmia and Jack to assist ergonomic analysis of actual and future activities. Further studies are needed to validate the application of the NIOSH software.

This dissertation details the synthesis with satisfactory reaction yields (between 56.3 and 96.5%) of mono- and bimetallic complexes of copper(II) and of cobalt(III), containing as ligands, tridentate and tetradentate Schiff bases. The compounds were characterized, for different techniques, such as melting point, elemental analysis, solubility in various solvents, conductometry, nuclear magnetic resonance (NMR) spectroscopy and spectroscopy in region of the IR and in the UVvis. The results of melting point indicate that the compounds have high purity and the elemental analysis showed consistent values. The solubility tests indicate different capabilities of intermolecular interactions and labilization distinct between the compounds. The obtained molar conductivities in electrolyte solution indicate proportions expected by the proposed structures. The obtained data by 1H and 13C NMR in compounds with cobalt(III) showed concordance with the proposed structures in solution. The spectra of the compounds in the IV region show proper bands, referring to the stretch of C=N bond, in the range of 1600-1650 cm-1, stretches relating to the bonds of the metal ion with the oxygen of the phenolate group, with chlorides and with the nitrogen atoms of the imine, amine groups, the imidazole and imidazolate were evidenced, besides to help differentiation of monometallic and bimetallic compounds. In the UV-vis region measured spectra were verified the presence of bands that should correspond to the electronic transitions of π → π* type which involve the molecular orbitals imine group (C=N), of bands d-d transitions due to the metal ion present also, but related transitions to the n→π* type were not verified. The compounds were tested as a catalyst in the oxidation of 3,5-DTBC and in studies of catalytic oxidation using O2 at 25°C were obtained values of enzyme kinetics parameters and these values are comparable with the literature, kcat = 1.28 x 10-1 s-1 εcat = 6.79 x 102 L mol-1 s-1 for CuCu3EtOtetraB (best of the series), there is evidence that the mechanism is different for each used complex.

In this work it was looked to establish a relation of as the curricular components of the current course technician in Chemistry of the Center Paula Souza can prepare level professionals technician for the agro-industries of the administrative region of Barretos. First one traced the industrial profile of the State of São Paulo and the industrial profile of the administrative region of Barretos, using itself given on employability and added value of some industrial subsectors. After that a survey on the industrial and laboratory processes of agro-industries of citric, bovine meat and sugar and ethanol was made, becoming related after that, of that it forms these processes if they relate with the curricular components of the current course technician in chemistry. From interviews in four different agro-industries of the region in study, if it evidenced the economic importance of the analysis laboratories, where if it believed that the technician in formation would be being prepared. But it was observed that the formed technician could work in any industrial sector, evidencing that its final formation if gave inside of the proper industry. It was verified that the curricular components take care of the demand for qualified professionals, since few industrial processes were not inserted in the curricular grating of the course. It was concluded that it is not necessary to change the plan of course and yes, to adapt it, guided for the industrial profile of the region. Work this that can be made by the proper professors of the course technician, guided for specialists in professional education of average level and studies of the recent changes in the industrial processes.

Among the challenges of educational inclusion, it stands out to ensure children with intellectual disabilities effective conditions for the development of their learning to read potential. To provide opportunities since early childhood education, in order to make students have active contact with reading and writing, shows itself as a favoring factor of Emergent Literacy development, that is, the knowledge and abilities related to reading and writing increase the chances of the child to succeed on learning to decode and understanding texts. This study had as main objective to build, implement and to analyze an Emergent Literacy promotion program for preschool students with intellectual disabilities guided by a teaching approach characterized as shared reading. The study had as specific objectives: to obtain a characterization of students Emergent Literacy abilities, in order to support the planning of the interventions; to describe the activities and adaptations of the material used by teachers and students in shared reading situations, considering the sessions held; to describe students engagement in shared reading activities; to analyze the main activities developed by the researcher in shared reading context, focusing the development of the different components of Emergent Literacy, as much as the adaptations in face of the different characteristics of the students. The participants were two students with Down syndrome, aged 3 to 5 years old, that attended a municipal center of early childhood education. This is a descriptive and exploratory study, because it searches a better comprehension of a so far little studied phenomenon. The program was applied individually, and was conducted by the researcher responsible for the study. The shared reading sessions were filmed, in order to obtain the descriptions related to activities and adaptations made by the teacher, as well as descriptions of students engagement on the activities. Shared reading sessions were made, which proposed activities that could promote familiarity with Emergent Literacy components. The program results point that the participants had systematic opportunities to explore books, choose them independently, of observing and listening to the researcher read a wide range of stories, and of participating in activities that required the presentation of behaviors associated to different components of Emerging Literacy. The results referred to the engagement on the activities point that through the sessions occurred an increase of the interest by books and readings, of the participation during readings, of the comprehension of the stories, on the proper handle of the books, and on the use of concepts about reading and its functions. The participants had opportunities to be involved in make believe readings and recognizing this concept. It is discussed the possibilities of continuing the study in view of the importance of demonstrating possibilities that come of efficient approaches for the promotion of Emergent Literacy among students with intellectual disabilities, in order to guide teachers work on early childhood education context.

In a context wich parties new dynamics, goals and articulations are object of analysis, this paper means to analyse the transformation in one of the most fundamental element of the political parties: it's ideological preferencies. Through the operationalization of a new variable called "emphasis on social politics", which uses the concepts of "left and right", this paper measures the ideologial preferencies by analysing the PT's and PSDB's 2002 and 2006 manifestoes. The main objective of this paper ir to test the operationalization of the method of analyse in the brazilian context through the hypothesis that the social politics were the main object in those two elections. Assuming that social politics were the main demands of the public in general, this theme may be also the main element that defines if a party is in the left side of the political spectre or in the right side of it.

The growing interest in studies of functional diversity allows to address the relationship between the functional characteristics of species with variations in the environment attempt to understand the organization of biological communities. We examined the relationship between physical and structural characteristics of 19 stretches of headwater streams in the Atlantic Forest and morphological characteristics related to swimming ability of fish species. The environment was described by altitude, distance from species pool, substrate composition and depth of the channel. The functional characteristics were described by 11 morphological measurements. The RLQ analysis was used and the first two axes explained 97.8% of the total variation. The first axis was interpreted as the action of the altitudinal/longitudinal gradient in the structuring of assemblies of fish which varied with morphological measurements of length of caudal fin and caudal peduncle. We can say that there are two distinct assemblies positioned at the extremes of the environmental gradient separated by capacity of swimming of the species. Within these groups we can say that on a local scale the physical structure of the channel generates subgroups related to the use of the niche, suggesting the action of environmental filters. Thus, we present evidence that environmental attributes of headwaters of the Atlantic Forest are related to the structure of the assemblies of fishes that inhabit these environments.
