This work deals with the application of two arrays of sensors composing an electronic tongue for the quality evaluation of UHT-type milk, with the specific aim of detecting the antibiotic tetracycline in this dairy product. The electronic tongue device was made up by sensing units composed by gold interdigitated electrodes assembled onto glass substrates. Polyamide 6 (PA6) nanofibers and PA6/polyaniline (PAni) blends were deposited on the electrodes via the electrospinning technique. The nanofibers were characterized by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), FTIR spectroscopy, Raman spectroscopy, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA/DTG). The electronic tongue measurements were carried out using an impedance analyzer to collect capacitance and resistance data at 1 KHz. As chemometric tool we employed the Principal Component Analysis (PCA) technique to verify the efficiency of the electrospinning nanofibers-based electronic tongue in distinguishing different types of milk, as well as those contaminated by tetracycline. The results showed that the use of PAni for obtaining polymer blend fibers caused some small changes on the physical chemical properties compared to the neat PA6 fiber. However, PAni addition allowed a great reduction on the fiber diameter. Our results demonstrated that the electronic tongue system is a potential methodology to be used for classifying milk samples, in terms of fat content and quality regarding the presence of antibiotic tetracycline. The electronic tongue system system was able to detect milk samples contaminated up to 1ppb of tetracycline, regardless of milk fat content.

In recent years we observed an increase in the number of computers, internet, software and other technologies and technological resources of information and communication in school environments (ALONSO, 2008; KENSKI, 2007; 2012). The educational use of technological information and communication resources requires the development of teacher knowledge (TARDIF, 2012) that allow the contemporary teacher pedagogical work through the digital society (KENSKI, 2012). In this context, the process of literacy and literacy remains fundamental. Thus, the main objective of this research is the reflection of teaching knowledge (TARDIF, 2012) for the use of these resources, specifically of educational software for literacy and literacy. Therefore, we aimed specifically: 1) mapping the use of digital technology resources in the investigated school units; 2) description and analysis of teaching experience with the use of educational software in the early years of primary education, specifically in literacy and literacy process (KLEIMAN, 1995; MONTEIRO, 2010; SOARES, 2004; 2013); c) research and analysis of the conceptions and methods of literacy and literacy activities that support the selected educational software. The research was guided on the qualitative method (LÜDKE; ANDRÉ, 1986), with a theoretical framework on the technological resources of information and communication, teacher training and literacy and literacy; mapping the use of educational software in six public schools in the early years of elementary schools of São Carlos/SP through questionnaires; interviews in two public schools, with teachers about their teaching and methodological experiences with the use of educational software in the literacy process and literacy and epistemological analysis of educational software. We seek to build theoretical knowledge that will permit the teaching critical look at these resources, basing the assessments of their potential and limitations for literacy and literacy. At the same time, scoring undertake knowledge teachers needed for teacher training, both initial and ongoing, for the critical use of these resources in order to insert them as educational and methodological resources complementary teaching practices. We observed that the educational context is a rich and important source in the consolidation of teaching knowledge (TARDIF, 2012) for both the use of ICT, and in relation to the methods and conceptions of literacy and literacy, and the experiential knowledge a rich source of learning and professional development. However, we also see the need for strengthening of knowledge on which to base concepts, methodologies and teaching about the literacy and digital literacy (FANTIN; GIRARDELLO, 2009) and media literacy (WILSON et al, 2013).

The fluid catalytic cracking (FCC) is one of the most important process in the petroleum refining industry, being responsible for the increase of the yield of the most valuable light hydrocarbons. On the other hand, the FCC process generates big amounts of CO, NOx and SOx emissions. The CO emissions from the most of pollution sources are abatement using noble metal based catalysts. However, the growing demand and scarcity of those metals have caused an increase in the process cost and consequently promoting studies to find alternative catalysts with comparable efficiency and lower in cost. In this respect, the literature had presented interesting results with transitions metal catalysts. Thus, the objective of this work was to prepare exchanged or impregnated Fe or Mn on H-mordenite or Ce-mordenite, which were evaluated between 150 and 550 oC in the CO oxidation with O2, in the presence or absence of interfering compounds (water steam or SO2). The catalysts were characterized by ICP-OES, DRX, DRS-UV-VIS and Mössbauer spectroscopy. The results showed that the preparation procedures of the interchanged or impregnated Fe or Mn catalysts were adequate, and no mordenite crystallinity loss was observed. Contrary to the exchanged Fe or Mn based catalysts, those based on impregnated Fe or Mn oxides showed a important potential as catalysts in the CO oxidation with O2. Then, in the applied operational conditions the Ce-MOR/Fe10, Ce-MOR/Mn5, Ce-MOR/Mn10 e H-MOR/Mn5 catalysts were able to produce an effluent with CO content lower than 500 ppm, which is the allowed limit by the environmental regulations related with FCC units. In the presence of water steam the evaluated Fe or Mn catalysts presented activity loss that was recovered after the elimination of that interfering from the feed. Nevertheless, in the presence of SO2, the tested catalysts showed an irreversible and significantly activity loss.

This current research, of qualitative nature, has been led by the question: which senses and meanings can be produced by undergraduate and graduate students while they experience, study and create teaching activities from a logical-historical perspective? Our aim was to identify and analyze the senses and meanings manifested by two subjects that composed a group of ten undergraduate and three graduate students, who gathered virtually and in person, over a semester, to reflect collectively upon the organization of teaching by means of teaching activities founded by the logical-historical perspective. To conduct the research, we sought theoretical fundaments in the logical-historical dialectical perspective on theoretical constructs that deal with Teaching Orienting Activities (AOE in Portuguese) and with the concepts of sense and meaning studied by Vygostsky. The gatherings took place in the context of the Integration, Teaching, Research and Extension Curricular Activity (ACTEPE in Portuguese) entitled: “When the history of Mathematics becomes a teaching methodology,” and they were split in three blocks: the first was aimed at motivation to work under a logicalhistorical perspective; the second one, at the study and deep analysis of it; and the third one, at the organization of teaching activities founded by this perspective. The following instruments were used to constitute research data: a field journal; narratives; audio recording of the gatherings, which were transcribed; forums held in a virtual environment; and propositions of activities that were designed or adapted by the participants and presented in the last gatherings. Upon these propositions and three specific criteria, two participants, whose trajectories were followed along the sixteen gatherings, were selected. The senses and meanings manifested by the subjects, in the context of the present study, show that organizing teaching from a logical-historical perspective can allow the involved students to seize the concepts through the exercise of thinking about them, making it possible for the learners to feel the need for developing the concept. They also show that the conceptual nexuses - both internal and external - are important theoretical constructs when working under this perspective, for they perceive internal nexuses as those which are not made explicit to the students by a formal concept representation, but they are fundamental to understand it. This meaning makes it important to evince these nexuses to organize teaching. Nevertheless, it is necessary to learn them and history can make it possible, for it holds the conceptual development process and the product of that development.

Leaf-cutting ants are considered the most derived insects on the planet. The performance in maintaining the aseptic conditions of the colonies is a key factor of the ecological success of these ants. Several defenses are used by ants, among them stand out chemical defense and mutualistic associations. The last of which is variable as it is dependende the species and / or environment in which they are the nests. So this article aims at a more detailed study the action of chemical defense mode, the form it manifests itself in different species of leaf-cutting ants, which have different degrees of derivation. The study was divided into two parts, the first investigated the chemical and histochemical composition of metapleural and labial glands of five species of leaf-cutting ants. Acids and hydroxy acids were identified and quantified, as main cosntituintes. These have antimicrobial action to pathogens present in the colony. The concentration and ratio of the compounds is directly related to species and variety. Histochemical analyzes revealed great similarity between species, demonstrating a relationship with the function of these glands. Enzymes that play an important role in the social order were evidenced by histoenzimáticos experiments. In the second part, as it was known the morphology of the glands, the search for inhibitors of enzymes present in the gland that provide natural protection to the colony to break the natural chemical defense. An enzyme that plays a major role in the secretion of acid is the fatty-acid synthase (FAS). At the present stage, cerulenin analogues were synthesized, known inhibitors of FAS in order to study the structure-activity relationship of these compounds.

This study analyzes the discourse on the success produced in contemporary Brazilian society. The corpus consists of editions of the magazine Caras and arising from the self-help literature books. More precisely, our research aims to describe and interpret the success of senses and subjects production process, to the extent that this is built by discursive practices of media and self-help literature, considering the fact that these discursive fields are privileged place of establishment of new subjectivities and new desires. Thus, this research aims to: 1) understand the meanings and the subjects produced among media, more specifically, in the magazine "Faces" in the issues of the first half of 2013, focusing on language resources, enunciative and textual employed in discursive constitution its publications, seeking to infer its recurrence in the production of certain effects of sense of success and their relationship with the interlocutors; 2) understand the meanings and subjects made in self-help literature, filigree, books whose titles are O sucesso está no equilíbrio (2006), O sucesso passo a passo (2010) and O sucesso de amanhã começa hoje (2005), in order to interpret their operating modes as tutorials to rise to success; 3) analyze the relationship of differences and similarities between the senses and subject these two forms of (re) production and spread of successful speech. Thus, we consider the postulate of speech analysis of formulated as follows by Orlandi (2012, 88 p.): subject and constitute sense while being identification processes based on the fact that a movement identity is history . If the subject and the senses are simultaneously at the meeting of the tongue with history, this meaning, speech, subjects and meanings of success will also be produced by speech. Before this situation, we propose in this dissertation expose a brief investigation of the senses on the speech of success in the current Brazilian society. Therefore, the methodological procedures used in the development of this work are based on qualitative research, the development of which we seek to identify linguistic-discursive regularities of statements of success and interpret the production of its subjects and senses through the development of parafrastics chains in order to infer its discursive formations.

This dissertation aims to investigate the medicalization device (dispositif) of children and teenagers inside the Brazilian public school (elementary to high school) in order to understand which effects have been produced in their subjectivities and their treatment, school and familiar history. We have used in this research the category named ?inconvenient? to speak of children and teenagers: those who do not learn what the school and the society want them to do but they can learn inside the school what this one does not expect them to do, i.e., they break the school discipline and the established order; they do not adapt themselves to the hegemonic models; they differ from what is expected, and therefore they are the abnormal and are deviant in relation to the existing rules. Discussing about medicalization is to talk about the way the management of life in all its instances has been built, it is to think of a dispositif that operates through the biopowers and produces biopotency. This research was performed in two moments, one quantitative approach and another, qualitative one. At first, we established the diagnoses of children and teenagers who were seen at the Mental Health Service system whose reports were taken from the diagnoses study found in the database of this health service. Subsequently, the main diagnoses of children and teenagers were identified related to the school complaints, according to the age and gender. From the descriptive analysis of the data, that is, from the diagnoses identified, we have found as a meaningful datum, the diagnosis of a disorder of school skills (F81) in a great proportion in the ages between 8-12 and 13-17 years-old. However, in the ages between 18-22 years-old, this diagnosis decreased and got a significant proportion in the diagnosis of Mental Retardation (F70). Hence, we have discussed that these provisional diagnoses in ..

Distillation is one of the most important industrial separation techniques. It requires high quantity of energy, corresponding to around 40% of the total energy consumption of chemical industries. As such, the optimization of a distillation column is indispensable, and it is only possible from the knowledge of the fluid dynamics phenomena occurring within the column. Some of models used for this, such as the models based on equilibrium and non-equilibrium stage concepts, usually provide useful results, but consider empirically many of the fluid dynamics phenomena by assuming a perfect mixture in each phase. In recent years, the advent of the high-speed computers combined with the development of accurate numerical methods for solving physical problems has revolutionized the way we deal with fluid dynamics phenomena. Computational fluid dynamics (CFD) techniques allow a microscopic description of the physical characteristics of the fluid motion. The main purpose of this study was develop a computational fluid dynamics model for gas-liquid flows that was able to predict the hydrodynamics and mass transfer on a sieve tray. A two-phase, three-dimensional and transient model, in an Eulerian-Eulerian framework was proposed for air/water (25°C) and ethanol/water systems at 1 atm. The continuity, momentum and mass equations were used to describe the gas and liquid phases. The sieve tray geometry simulated was based on experimental work of Solari e Bell (1986). The variables predicted were the velocity profiles, volume fraction of each phase, clear liquid height, recirculation areas, mass fraction and efficiency. The hydrodynamic and mass transfer model predictions were compared with experimental and numerical data from some authors and presented good agreement. This study shows that CFD can be used as a powerful tool for sieve tray simulation.

The Doctor-Patient Relationship has been identified as an important variable in Health Care’s adherence, efficiency, and effectiveness; The Doctor’s Social Skills, seem to be essential components in its establishment. The general aim of this study was to evaluate doctors’ social skills who works in social and private health systems, examining the relations between these skills and patient satisfaction with regard to the medical consultation. The Study 1 describes the Matched-Pair Instrument (MPI)’s translation and cultural adaptation; the instrument assesses doctor’s social skills during a consultation. Nineteen (19) individuals were involved in the translation and adaptation process. Psychometric analyzes showed satisfactory internal consistency for the patients version (Cronbach's alpha: α= 0,893), presenting similar properties to the original version. The Study 2 aimed to evaluate the social skills of doctors in both Social and Private Health System, considering the self-perception of the professional and the patient’s perceptions, and, examining how the interaction of these variables influence on patient satisfaction. The participants were 195 patients and 30 physicians, distributed in both health systems. The instruments used in the study were: the translated and validated version of the Matched-Pair Instrument (MPI), a Partial Version of the Social Skills Inventory (HIS-Del-Prette), and the Medical Care’s Patient Satisfaction Evaluation Questionnaire (QASPAM). The overall average scores in the MPI for both Patients (M = 77.5, SD = 12.3) and Physicians (M = 76.5, SD = 11.8) showed low, positive and statistically significant correlation (r = 0.16, p = 0.030); The Patients showed significantly higher ratings than the Doctors’ one. The professionals of social health system evaluated themselves as less skilled (M=69,93; SD=13,55) than the participants of private system (M=76,5; SD = 10.1). These data were similar to those obtained in the analysis of the patient’s questionnaires, since the overall average of public system patients (M=72.31; SD= 12.25) was significantly lower than the average of the private system (M=80.80; SD= 10.59). The professionals who worked in both health systems rated themselves, and were rated by their patients, as significantly (p <0.000) more skilled in the private system consultation than in the social one. Patients showed satisfaction with the service offered in both social and private health systems; however, private attended patients presented higher satisfaction’ scores. The scores levels of discontentment in the socials’s attended patients were relatively higher than those of the private system, especially in the following items: The Waiting Time in the office, before the consultation; the duration of the medical consultation and Medical Sensitivity. Future research have been suggested to increase the validity of the instruments used for the investigation. The results of this study seem to show that physicians who work in the private service evaluated up and received more satisfactory evaluations of their patients, in relation to social skills and satisfaction with care, than those who work in the public service. The data obtained in this study emphasized the relevance of both evaluation and training social skills for health professionals.

The 1940s is marked by a significant interest in the history of the portuguese language providing for themselves the moment of eruption of the Brazilian linguistic. Although there were already before this period of study, many studies seeking to understand and investigate the language in Brazil especially from the viewpoints grammatical, historical and dialetological and textual criticism, is the publication of Principles of General Linguistics in 1941, of Joaquim Mattoso Câmara Jr., a paradigm shift was seen in the Brazilian language of history and its moment of eruption in this scenario. This work would, strictly speaking, the transition between a traditional linguistic and modern (structural). Over the past few years, such studies in Brazil have grown a lot, we can say that came out of complete anonymity with Mattoso of pioneering work and they arrived, in 2015, as one of the most prolific Brazilian science, given the large number of presentations and publications work relevant events and magazines in the area in Brazil and abroad. The Brazilian linguistic also has little research, especially in the context of discourse studies, seeking to explain the history. Thus, this final work, we aim to investigate the event of reception Course of General Linguistics (CLG) in three Brazilian linguistics manuals: Princípios de Linguística Geral, of Mattoso Câmara Jr.; Fundamentos da Linguística Contemporânea, of Edward Lopes and; finally, Para Compreender Saussure, of Castelar de Carvalho, considering as an object of reflection the concepts of language and speech. Therefore, we anchor our work in theoretical and methodological assumptions of the french orientation of Discourse Analysis. We mobilized, more specifically, the contributions of Jacques Guilhaumou (2009) with respect to event concepts and discursive event of the narrative. We attend a corpus consisting of linguistic manuals published in Brazil from the forties of the last century, seeking to explain and / or didactic of the CLG. We seek to investigate the role that such textbooks assume from the interpretation of the reading of Saussure's Course, contributing in this way to a discursive elucidation of historical paths, beside, how they pass or passed the linguistic practiced in Brazil, as well as analyze the different effects directions created from different narratives produced.

This research is in the context of Brazilian historic farms that were responsible, especially at national economic development from the cultivation of coffee between the seventeenth and nineteenth centuries. Different research groups have come together to develop and implement a methodology for cataloging and inventory cultural property of these farms making them available in a free software called Virtual Memory (VM). The VM is a system developed on an open source platform under GPL (General Public License), and allows you to store different types of historical collections, whether bibliographic, museum, archives, architectural and natural in a single database. It was initially developed by Science course researchers Computing, University of São Paulo (ICMC / USP), on the campus of São Carlos - SP, with its prototype ready for testing. Currently these surveys were concentrated in the project "Criteria and methodologies for carrying out the São Paulo cultural heritage inventories", supported by FAPESP. One of the results of this project was the development of a Standard Description Information (SDI) that supports the provision of content on VM. With this approach the following specific objectives were established: Compose a descriptive mapping of the studies developed in the Brazilian Information science concerning the development of concepts, theories, methods and tools focused on description, organization and representation of the National Rural Heritage. Recover, detail and describe the procedures already developed in earlier research, focused on the collection of words related to Paulista Rural Heritage. Specifically consider international standards for Organization and Retrieval in Information Science among them the ANSI / NISO Z39.19-2005. Develop an introductory structure of taxonomy, to be incorporated into the VM as a resource for indexing of cultural goods which are likely to be registered, listed. As a result, an initial structure was built in 3639 with taxonomy terms, hierarchically structured and with signs of use. The largest order related to the development of this memory environment ranges from the preservation of references of tangible and intangible heritage of Brazilian historic farms to the systematization of information that can improve the formulation of public policies for heritage education, and in this sense, any tool that allow optimize the recovery processes of information about cultural property, are welcome.

The Post-Graduation system in Brazil is a strategical factor to the socioeconomic and cultural development process of brazilian society, marched by a strict evaluation process and recognition of the Post-Graduation Program (PGP) by the national and international scientific community. The evaluation process stands in this system managed by "Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)" and besides the initiatives of CAPES in endow the country with an efficient database about the situation and evolution of Post-Graduation, there is a underutilization of information by the factors involved on National Post-Graduation System (NPGS) due to form and volume of available data. The general object of this own paper work is the elaboration and review of indicators based on data of NPGS present on Indicators Notebooks of Courses Recommended and Recognized by CAPES, in area of Engineering II. The method used was the exploratory case study and the case unity was the knowledge area from CAPES Engineering II: subarea Materials Engineering and Metallurgic. Collected the data from Notebooks of Bibliographic Production of PGP on area as a documental strategy. Also, was used bibliometrics as technique of information analysis to the elaboration of Bibliometrics Indicators with the support of Software VantagePoint. As results was elaborated and reviewed the indicators of scientific production from PGP: collaboration between the PGP, the evolution of publications, the representativeness of PGP, ranking of periodic and main areas of knowledge. It concludes that the Indicators Notebooks by CAPES consolidate a national source of information, public and with easy access of scientific production national that enables the construction of suitable indicators to decision making process ordering improvement of PGP and the public politics of C&T.

It starts from assumption that primary health care has not been able to significantly change the model. The objective of this study was to analyze the merger of shares and public health technologies in the production of primary health care in different cities in the state of São Paulo from the perspective of Organisers of primary care. This is a descriptive and exploratory qualitative research. Study participants were the organizers of basic health care for the RRAS 13. To collect the data, we used semistructured interview technique and data analysis to thematic content analysis of Bardin. The results of this research are presented in the form of three articles, the first article, entitled "Primary Health Care: perceptions, knowledge and experience of the organizers of primary care" discussed the categories: a basic health care "is not staying on the base basic "; the articulator of primary care, professional approach and key in strengthening the link between state, county and health teams; the organizers of primary care program: a right initiative. The second article "The development of public health actions in articulating perspective of primary care" discussed the concepts that support the actions of public health; difficulties in the development of public health actions; facilitators contexts of public health actions; proposals to advance the construction and development of public health actions. The third article "public health practices in primary care" discussed collective health practices in primary care; and health surveillance practices. The results showed that the health teams have been building heterogeneously actions of public health in primary care.

Stroke is one of the chronic diseases that cause impairment, mainly motor and cognitive ones, which can compromise the functional capacity, making the subject dependent of care. In this context, it is family s responsibility to take care for the ill individual, assisting him in several everyday activities. The possibility of being a caregiver causes many changes in family dynamics, in the roles and in people's everyday lives. The extended period of care dispensed to the ill individual can also generate overburden and pain and hence threats to the quality of life of caregivers. This study aims to verify the presence of correlations between the level of independence and cognition in subjects with stroke and the level of overburden, pain and quality of life of their family caregivers. We sought to identify if the variables: age of the subject with stroke and caregiver, length of injury, rehabilitation and dispensed care, per capita income, physical, psychological, social and environmental aspects of family caregivers interfere in this relationship. Therefore, we adopted a correlation research with a quantitative approach. The sample consisted of sixty (n = 60) subjects, of which thirty (n = 30) were adults, male, with stroke diagnosis for more than six months and placed in rehabilitation services; and the other thirty (n = 30) their respective family caregivers, who had dispensed care to these individuals for more than six months. To collect data, we proceeded with the application of an (i) Form with data about the subject with stroke, (ii) Mini-Mental Scale and (iii) the Functional the Independence Measure (iv) Form caregiver identification, to (v) Zarit Burden Interview Scale, the (vi) Visual Analogue Scale of Pain and (vii) WHOQOL Bref, and (i), (ii) and (iii) were applied to subjects with stroke and (iv), (v), (vi) and (vii) to their family caregivers. Data analysis is based on a quantitative approach, using three forms of analysis, namely the simple descriptive, factorial and the Pearson correlation coefficient. In results, we presented findings that subjects with higher dependence levels were related to a greater number of cognitive impairment resulting from stroke and the need for further rehabilitation time as well as caregivers of over burdened stroke subjects showed higher levels of pain, with the latter conditions also related to lower levels of quality between them. It s concluded that this research provided important data which can foster new public policies, as well as actions related to Occupational Therapy, especially the ones which include the familiar caregiver.

In this work, different commercial carbon materials that could be used as electrodes for capacitive deionization were investigated: carbon cloth, carbon foam, carbon felt, carbon fiber, carbon veil and activated carbon powder (AC). The materials were characterized by scanning electron microscopy (SEM), surface resistivity, wettability and cyclic voltammetry (CV). The performance in terms of electrosorption of NaCl was evaluated for different cell potentials. The AC electrode showed the best capacity of removing ions, and presented good values of charge efficiency (QE) and specific energy consumption (η) and, thusly, it was chosen to be modified using different techniques in an attempt to improve its characteristics aiming better results of electrosorption. Part of the strategies was the addition of carbon black and sodium chloride in order to improve the electrode conductivity and its macroporosity, respectively. A factorial experimental design was used to evaluate the effect of the AC mass, NA, mass of sodium chloride used in the electrode preparation and also the cell potential, on the capacity of removing ions (R), QE and η. The variables that showed the greatest effect on the CDI process was the cell potential and the AC mass (that create different thickness for the electrode). In spite of increasing the electrode conductivity, the NA did not show any improvement on the electrosorption of the electrode. Afterwards, an individual analysis showed that the use of sodium chloride to increase electrode macroporisity improved the capacity of the electrode to remove ions but just for the thickest electrode. However, it was verified that the increase of the thickness did not implied in a linear increase of the ion removal capacity. This behavior may be attributed to the non-uniform distribution of the electric field on the porous film. Thusly, even the thicker electrode showing a better capacity of removing ions, a great part of its mass was not being used for electrosorption. Additionally, the increase of the thickness led to a decrease on desorption. Those results indicate that the electrode thickness must be optimized. Another strategy to improve the electrode wettability and capacitance was the deposition of silica and alumina. It was observed an improvement on the wettability of the electrode, however those electrodes voltammograms showed an increase on the resistivity and as result, besides not presenting any improvement on the capacity of electrosorption, there was still a reduction of the ion removal kinect. Finally, the last strategy used to improve the AC electrode was the addition of the conducting polymer polypyrrole aiming to improve the electrode capacity of removing ions through the pseudo capacitance effect. The addition of polypyrrole increased the total of ions removed from solution, however, in all the cases, the values of QE and η were worse than those observed for the AC electrode. Due to the polypyrrole characteristics, the drying temperature used to prepare the electrode was reduced from 130°C to 80°C and when this temperature was reduced, it was verified that this variable had a strong effect on improving the capacity of removing ions and the energy efficiency of the AC electrode.

In this work the application of electrodes based on a composite of Vertically Aligned Carbon Nanotubes and Graphene Oxide (VACNT-GO) as electrochemical sensor for the determination of pharmaceuticals from the statin class was explored. The VACNT-GO composite was synthesized by the Microwave Chemical Vapour Deposition (MWCVD) method, followed by oxygen plasma treatment. Using high-resolution scanning electron microscopy, Raman spectroscopy and X-Ray photoelectron spectroscopy, it was possible to verify the exposition of graphene sheets functionalized with oxygenated groups (graphene oxide) in the VACNT tips after the oxygen plasma treatment. The oxygen content increased from 4.9% for the VACNT sample to 21.4% in the VACNT-GO sample case. Furthermore, the C:O ratio was equal to approximately 1.5 for the VACNT-GO sample, in accordance with the expected range for graphene oxide. Moreover, by measurements of the contact angle with distillated water, it was noted a drastic change of the sample surface wettability, changing from superhydrophobic for VACNT (contact angle = 157o) to superhydrophilic for VACNT-GO (contact angle ≈ 0o), enhancing the electrochemical application of the material in aqueous systems. From cyclic voltammetry assays conducted for the potassium hexacyanoferrate (III) probe, it was diagnosticated an electroactive area equivalent to approximately 80% of the geometric area and a high heterogeneous electron transfer rate constant (3.4 × −2 −110 cm s ) for the VACNT-GO electrode, demonstrating the good electrochemical performance of the proposed electrodic material. Next, voltammetric methods for determination of the statins atorvastatin calcium (ATOR) and rosuvastatin calcium (ROS) were developed. Using Differential Pulse Adsorptive Anodic Stripping Voltammetry (DPAdASV) under optimized conditions, the constructed analytical curve for ATOR was linear in the range −8 −6 −1 −9from 9.0 × 10 to 3.8 × 10 mol L , with a limit of detection of 9.4 × 10 mol −1L . In the ROS drug case, the Square-Wave Adsorptive Anodic Stripping Voltammetry (SWAdASV) technique showed the better analytical performance, and also under optimized conditions, the analytical curve was linear in the ROS −7 −5 −1concentration range from 4.8 × 10 to 4.7 × 10 mol L , with a limit of −8 −1detection of 6.0 × 10 mol L . Both the voltammetric procedures were successfully applied in the ATOR and ROS determination in pharmaceutical formulations and synthetic biological samples (urine and human serum).

For many people, text proofreading is something purely exclusively technical, in virtue of their disregard for the complexity of the proofreading processes, such as suggestions made on another person’s text: which has a normative dimension, and thus ideological implications. In this context, we analyze discourses about reganding proofreading, materialized in texts collected from different forums. The goal is to understand the dynamics in which certain discourses are told (or untold), and how they are constructed by others in the traces where emerges a figure of the reviewer. Our corpus consists of a set of data: (i) discourses about the proofreading practices, putted into circulation in different spaces, such as foruns and specific courses for professional readers; (ii) texts relating to text revision practices in a Facebook community called Reviewers; and (iii) notes from editorial Co-enunciator engaged in a process of editing a distance learning textbook. The discussion is based on the theoretical concepts developed by Dominique Maingueneau (2008, 2010) in order to apprehend the Discursive machinery as enunciation scenes that implies a discursive ethos. It allows us to analyze the discursive place occupied by the editorial mediators, looking for the figure of text reviewer. Considering this issue, we also investigate, through the notion of editorial genetic rites proposed by Salgado (2011), the historical, opaque and heterogeneous conditions of the linguistic material with the text reviewer works. The theoretical and methodological guidelines are justified as far as the reflections leads us to a collective complexity, connecting different places and memories, revealing the central position of proofreading activity the publishing.

Background: Patellar tendinopathy (PT) is an overuse injury, but the factors that contribute to tendon overload are still unknown. The high prevalence of this injury in jumping athletes may be related to hip extensor and ankle plantar flexor weakness, which could lead to a preferential use of the quadriceps to absorb the impact forces acting on the lower limbs during landing. However, no previous study has evaluated hip and ankle strength in subjects with PT. Therefore, the aim of this study was to evaluate the eccentric hip and knee extensor and ankle plantar flexor peak torques and the knee/hip and knee/ankle ratios in athletes with symptomatic PT (SPTG), athletes with asymptomatic patellar tendon ultrasonographic abnormalities (APTG) and healthy controls (CG). Methods: Seventeen athletes (volleyball, basketball and handball) between 16 and 35 years of were enrolled in this study. They were divided into three groups: SPTG (n=6), APTG (n=5) and CG (n=6). Eccentric peak torque was evaluated with an isokinetic dynamometer. Differences between groups were evaluated by multivariance analysis (MANOVA) and the Tukey post-hoc test (α=0.05). Results: The SPTG had a lower eccentric knee extensor torque than the APTG (p=0.047) and the CG (p=0.035), and the APTG had a higher knee/ankle ratio than the SPTG (p=0.015). Conclusions: The SPTG had lower knee extensor torque than the other groups, which may have been due to pain inhibition. Additionally, the APTG had a higher knee/ankle ratio than the other groups, which may have been related to increased patellar tendon load. Prospective studies are needed to investigate whether these aspects are risk factors for PT.
