Automatic Multidocument Summarizarion (AMS) is a computational alternative to process the large quantity of information available online. In AMS, we try to automatically generate a single coherent and cohesive summary from a set of documents which have same subject, each these documents are originate from different sources. Furthermore, some methods of AMS select the most important information from the collection to compose the summary. The selection of main content sometimes requires the identification of redundancy, complementarity and contradiction, characterized by being the multidocument phenomena. The identification of complementarity, in particular, is relevant inasmuch as some information may be selected to the summary as a complement of another information that was already selected, ensuring more coherence and most informative. Some AMS methods to condense the content of the documents based on the identification of relations from the Cross-document Structure Theory (CST), which is established between sentences of different documents. These relationships (for example Historical background) capture the phenomenon of complementarity. Automatic detection of these relationships is often made based on lexical similarity between a pair of sentences, since research on AMS not count on studies that have characterized the phenomenon and show other relevant linguistic strategies to automatically detect the complementarity. In this work, we present the linguistic description of complementarity based on corpus. In addition, we elaborate the characteristics of this phenomenon in attributes that support the automatic identification. As a result, we obtained sets of rules that demonstrate the most relevant attributes for complementary CST relations (Historical background, Follow-up and Elaboration) and its types (temporal and timeless) complementarity. According this, we hope to contribute to the Descriptive Linguistics, with survey-based corpus of linguistic characteristics of this phenomenon, as of Automatic Processing of Natural Languages, by means of rules that can support the automatic identification of CST relations and types complementarity.

Some conservation actions require the knowledge of the geographical distribution of species, however, this knowledge is far from being achieved for most species. The species distribution models (SDMs) have proved a useful tool to predict the distribution of species and guide field research to find new records. The SDMs using field data occurrence and environmental variables to indicate potential sites for the occurrence of a species. The quality and quantity of the data used are important to a successful result prediction models and application to conservation. The choice of environmental data and the algorithm and their settings are important for the development of models, the choice of these variables have directly influences to the quality of the models. Another very important step in modeling is the quality assessment and validation of the model, is that it may decrease the risk of accepting as true models with gross errors. The objective of this study is to evaluate the applicability of models generated by MaxEnt to find new populations of plants considering different data configurations used. For this, considering that the field validation is the most appropriate in the literature, but the most costly, the first chapter proposes a validation methodology of the models as easy application field. The methodology was able to find new records in the field, therefore, indicated for the validation of models. In the second chapter, knowing of the existence of a wide variety of variables that influence the performance of the models, the aim was to test the influence of the sample size, the spatial bias, the set of climate data and settings available for the MaxEnt algorithm in the areas of prediction potential distribution. The results demonstrated that the use of sampling and climate data restricted to the limit of the study area and also the use of soil data generate more accurate models.

The popularization of mobile devices capable of communicating via wireless network technologies allows us to consider different scenarios in which these devices may autonomously interact with each other. The envisioned communications would occur in a P2P fashion, as each device could simultaneously provide and consume services. A mechanism for dynamically discovering nearby devices and the available services would be necessary. Although a few existing applications already provide the direct interaction among devices they are purpose-specific and rely on pre-configured information for identifying other devices. A service-oriented architecture (SOA), based on HTTP requests and the REST or SOAP protocols, is commonly used in this type of communication. However, automatically finding available known services is still challenging. Service discovery is usually based exclusively on service name, which is not very flexible. This work proposes a new model for the direct interaction between computing devices. In an attempt to facilitate service discovery and selection we propose a content centric model in which interactions are defined according to an object’s type and the action to be applied to it. The proposed approach can workatop of existing discovery protocols, based on extensible metadata fields and on existing service data. Our proposal is evaluated according to i) the viability of direct communication between nearby devices, even when carried by users or associated to vehicles; ii) the proposed service discovery and matching using the content centric approach; iii) the effectiveness of a middleware to support the development of generic applications for direct device communication. Simulation results show our proposed model is viable. A preliminary implementation of the middleware was also evaluated and the results show that spontaneous, opportunistic, service-based interactions among devices can be achieved for different types of services.

The object of this work was to develop a panel about the installed institutional capacity in the municipalities of Ribeirão Bonito and Dourado – State of São Paulo, while characterized as small municipalities around an important country development center, the city of São Carlos. Therefore, it was made an analysis starting from the polysemic concept of Development, dissociating it from a mere economic growth, but adding to it the New-Developmentalism characteristics experienced in Brazil from the XXI century forth related to income distribution policies and popular empowerment. After that, it explains the difference between this phase and the nationaldevelopmentalism era of the second half of the XX century, when the logic of development was mostly an economic subject. Leather then go to an analysis of the characteristics of the state capacities required to this State in order to understand how this can promote the development of remote or small communities and devoid of endogenous possibilities for social transformation. It concludes with the presentation of a diagnosis of the State presence in these cities, in order to demonstrate how the regional public university, understood as an entity of the federal State, can contribute greatly to the training of agents of those communities in order to promote the development of their territories.

In this work, a photometer/fluorometer micro-controlled (P2FM) multifunctional, portable, communicated by USB 2.0, robust, easy handling and with low consumption of energy was developed. The P2FM was built using a micro-controlled (PIC-18F2455) as central unit of process (CPU), two tricolors LEDs (470, 528, 621 nm) as source of radiation, a multichannel sensor (TCS3200) and the management program wrote in Visual Studio. One of the two LED was used as radiation source for photometric mode. The TCS-3200 is a multichannel sensor with four photosensitive tracks: 480, 540, 750 e 830 nm, being that selection of track is performed by program controlled. The management program operates sending functions for microcontroller, record of dates and storage of signal (*.txt) through of USB port 2.0 (5.0 VCC, 300 mA). The P2FM is compact, with 3.5 cm × 7.0 cm × 8.5 cm size and 159.4 g of weight, considered as a portable device. In the program is selected of function mode: photometer or fluorimeter. In the analytic performance test by photometric mode, were used three solutions amaranth (AM), blue light (AB) and tartrazine (TT). The detection limits obtained were 1.6 × 10−7, 5.4 × 10−7 e 1.9 × 10−6 mol L−1 for AM, AB and TT, respectively. The quantification limits obtained were 4.8 × 10−7, 1.6 × 10−6 e 5.9 × 10−6 mol L−1 for AM, AB and TT, respectively. The correlation coefficients were AM = 0.997, AB = 0.975 and TT = 0.994. The analytic performance for fluorometric mode was carried using in both fluorescein (FL) and Rodamine 6G (R6G) solutions, were obtained a detection limit of 8.3 × 10−8 and 4.79 × 10−8 mol L−1, respectively for FL and R6G. The correlations coefficients were 0.997 for FL and 0.999 for R6G. Also, the proposed device was successfully used to sulphite determination in drinks, total hardness in water, determination of stability constant and study of stoichiometry of a chromogenic complex, aiming to show any applications of photometer/fluorimeter. The constant of formation obtained was 5.04 × 1018 is concordant with that presented in previous reports 6.2 × 1018. In sulphite determinations on eight samples of drinks, the paired studen’s t-test showed that reference method and photometric method using P2FM was 0.66 times smaller than critic value (2.36, α = 0.05). The total hardness in water was determined by fluorometric method, being that the P2FM showed best sensibility 8.94 × 106 that a determination using the RF5301/PC spectrofluorometer. The paired studen’s t-test (α = 0.05) no showed significant differences, calculated t (0.36) small than tabulated t (2.01).

A software concern may be defined as a set of requirements related to the same purpose. A CrossCutting Concern (CCC) (or Early-Aspect) is a concern whose requirements cutacross other concern requirements and the inadequate modularization of this type of concern may hinder the software development and evolution. The Aspect-Oriented Requirements Engineering (AORE) area provides more appropriate strategies for CCC identification, representation and composition. A commonly reported issue on AORE approaches is the low effectiveness provided by them, regarding to the concern identification and classification. This is due to two main causes: (i) the lack of a broader understanding about software concerns domain; and (ii) the lack of appropriate resources to support software engineers during the identification and classification of software concerns. This work aims to mitigate the reported issue by dealing with its main causes. To do this, we present: (i) a reference ontology for software concerns domain, called O4C (Ontology for Concerns), that aims to make clear and precise the description of the elements of this domain; (ii) an ontologically-based AORE approach, called ObasCId (Ontologically-based Concern Identification); and (iii) a computational tool, called OBasCId-Tool, that automates some activities of the ObasCId approach. The evaluation of the proposed approach and its computational support was carried out through experimental studies, in order to verify the effectiveness and efficiency of these research products regarding to concern identification and classification. The results indicate the ObasCId approach may contribute positively to the recall of software concerns without harming the precision and the execution time of the approach. Regarding to the ObasCId- Tool, it has been considered approved by its users, regarding to its usefulness and easeof- use features.

The popularity of social networks have attracted attention of companies. The growing amount of connected users and messages posted per day make these environments fruitful to detect needs, tendencies, opinions, and other interesting information that can feed marketing and sales departments. However, the most social networks impose size limit to messages, which lead users to compact them by using abbreviations, slangs, and symbols. Recent works in literature have reported advances in minimizing the impact created by noisy messages in text categorization tasks by means of semantic dictionaries and ontology models. They are used to normalize and expand short and messy text messages before using them with a machine learning approach. In this way, we have proposed an ensemble of machine learning methods and natural language processing techniques to find the best way to combine text processing approaches with classification methods to automatically detect opinion in short english text messages. Our experiments were diligently designed to ensure statistically sound results, which indicate that the proposed system has achieved a performance higher than the individual established classifiers.

Background: Shoulder impingement syndrome (SIS) is a common cause of shoulder pain complains and numerous treatment strategies are available in the clinic. Questions remain regarding the effects of Thoracic Spinal Manipulation (TSM) on SIS and concerning the efficacy of available techniques on the treatment of this population. Objectives: In a clinical trial, the objective was to evaluate short-term effects of a TSM on pain, function, scapular kinematics and scapular muscle activity in individuals with SIS. In a systematic review, the objective was to summarize current evidence regarding effectiveness of physical therapy to improve pain, function and range of motion in this population. Methods: In the clinical trial, participants were randomly allocated to TSM group (n=30) or sham-TSM group (n=31) and attended 2 intervention sessions over a 1-week period. Shoulder pain, shoulder function (DASH and WORC questionnaires), scapular kinematics and scapular muscle activity were measured. A blinded assessor evaluated the outcomes at day 1, day 2-pre, day 2-post and day 3. In the review, Pubmed, Web of Science, CINAHL Cochrane, Embase, Lilacs, Ibecs and Scielo databases were searched up to April 2015. Randomized controlled trials investigating different modalities of physical therapy in the treatment of patients with SIS on pain, function/disability or range of motion were included. Results: In the clinical trial, TSM group improved pain (1.1 points) and tended to improve function (5.0 points on WORC) over the sham-TSM group after 2 intervention sessions. Scapular upward rotation increased 4.0°, 5.3° and 3.3° at day 2-pre, day 2-post and day 3, respectively, in the TSM group during lowering of the arm. Changes in scapular internal rotation and tilt were not different between groups. Upper and lower trapezius activity decreased in the TSM group and both groups, respectively, during elevation and lowering of the arm. Serratus anterior activity increased in the sham-TSM group. In the review, sixty-two RCTs were included. The majority had a low to moderate risk of bias. Exercise therapy provided high evidence of improvements to the treatment in the short, mid or long-term. Dynamic humeral centering, proprioceptive exercises and manual therapy associated with conventional exercises enhance the improvements in the short-term. Low-level laser, ultrasound, pulsed electromagnetic field and kinesio taping provided moderate and high evidence level towards no benefits to the treatment of SIS. Microwave diathermy, transcutaneous electrical nerve stimulation and isolated manual therapy or acupuncture provided limited evidence of benefits. Conclusion: TSM may be worthy to achieve short-term reduction of shoulder pain, increase of scapular upward rotation and decrease of upper trapezius activity facilitating the application of other movement-based interventions in individuals with SIS. Exercise therapy should be used as the first choice to improve pain, function and range of motion, and the association of manual therapy should be the best choice to accelerate symptoms decrease and progress exercise therapy quickly. Low-level laser therapy, ultrasound, pulsed electromagnetic field and kinesio taping do not provide significant effects to the therapy and therefore could be avoided. More studies are necessary to improve evidence concerning effects of diacutaneous fibrolysis, microwave diathermy, transcutaneous electrical stimulation, acupuncture and isolated manual therapy techniques in the treatment of SIS.

The aim of this work is to clarify the problematic relationship between subjectivity and transcendence in the Logical Investigations of Edmund Husserl. To this end, we draw a genesis of this problem, from the period prior of this work in question, until the end of his explicitness on Prolegomena. Such problematic relationship arises in Husserl combat against the psychologists conceptions of the end of sec. XIX, and, we sustain, is the biggest concern of this author throughout the course of the Investigations. What we will show in our work is how at the end of refutation of psychologism, is left to Husserl explain how can subjectivity and transcendence get in relation, since Prolegomena put such instances as separate natures, the legacy problem to the rest of the Investigations is to show how an act of judgment, which is a subjective experience, the subject enters into a relationship with the object judged by this act, the instance that transcends such subjectivity. The Husserl's answer is to present a discipline, phenomenology, which seeks to describe within the subjective, in the experiences of knowledge, the essence of the modes this subjective dimension refer to objects that transcend itself. We will explain how even after denying psychologist attempt, such a notion operates negatively throughout elaboration of the phenomenological method, that is, the phenomenology is as an overcoming of psychologism, in its most fundamental flaws.

Electricity in Brazil is mostly generated by hydroelectric plants that depend on the volume of water in their reservoirs. Due to the fact that rainfall is decreasing, other methods with higher costs to generate energy are required. These costs are passed to users, increasing the energy bill. Futhermore, the wasting of energy and overconsumption also contribute to increase the energy bill. At the same time, the wasting of energy are not noticed by the user. To avoid such wasting, an alert could be sent as soon as an anomalous event is detected. In this way, we propose a system that sends an alert of any novelty detection in energy consumption through the analysis of the methods Sliding Window, Exponentially Weighted Moving Averages, Clustering, Average per Circle, Average per Stage, Gauss Distribution and Self-Organizing Novelty Detection. Results demonstrate that the methods evaluated are efficient in real time detection of novelties, presenting 90% of accuracy and 10% of recall, besides a low delay to send the alert.

The Health care is characterised as a social practice – where the people who learn and teach – influenced from values and culture, that vary according to the social groups and the family, economic and social system. In the pregnancy, the woman experiences several changes, becoming a propitiated period for restructuration, including the way that she cares about her health. The objective of this research is the understanding of the meanings of the popular practical’s and knowledge of the pregnancy’s health, starting from the perspective of the pregnant women that attended an educational action at a Unit of Family’s Health (USF) from Piracicaba. This is a research with a qualitative approach and inspired in the assumptions of the participative observation, having as collaborators, five pregnant women, whose made part in the course offered in the USF São Francisco, in which the researcher was inserted. The database collection occurred in the period of October 2014 to July 2015 and involved chat groups and interviews in depth, that were recorded and reproduced. The analysis of the data were based in the Thematic Analysis. For the collaborators, the health is related to the wellbeing and self-care, involving physical, emotional and psychological aspects. The pregnancy was described as like a magic moment, a momento of joy, grace and achievements, but scary in the beginning involving adaptation and difficult moments. They felt more sensitive, anxious, with intense emotions, ambiguous and unsteady. As positive points, they have mentioned the interaction with the baby and a better treatment received form the Family and the unfamiliar. Among the practices considered positives, appeared healthy food and water intake; physical exercises; prenatal, tests and vaccines; rest. The practices considered damaging, were to be nervous; marital fights; excessive physical attempts; consumption of alcohol, cigarettes and/or drugs. Although they praise healthy food, the food culture and the habits dominated and the collaborators claimed that ate what they felt like eating. The main highlighted discomforts were sickness and nausea; pain in the legs, backache and headache; low pressure and difficulty to sleep. Among the practices to minimize, were to be more selective in what to eat, be alone, lay down, put the feet up, breath, rest, find other positions to sleep. The majority avoided to use medicine during the pregnancy, perhaps they were afraid to prejudice the foetus, perhaps because of the side effects or even inefficiency. In relation to the educational processes related to the health care, the collaborators mentioned that learned with relatives (specially women), colleagues, experienced people, health professionals, sharing knowledge, through the intimacy, talks, warnings; lectures, lessons, courses and queries; internet research, mobile applicative and television programmes. When living the maternity, they claimed that they felt more mature, wise, responsible, more careful and also more kind and comprehensive with other people, noticing priority changes, in the way of thinking and facing the world and the problems, retrospection their values. This research, besides the investigation of the knowledge and popular practices, also clarified the form, with who and where the women learned and taught about the health care. Thus, we aim to bring contributions to the health and educational area, encouraging the popular education, the humanization, the dialogue and the shared construction of knowledge.

This paper presents a model which aims to stimulate the creation of academic spin-offs by Brazilian Scientific and Technological Institutions (STI), based on experiences of the University of Georgia, University of California, Polytechnic University of Valencia and University of Porto - institutions with high rates of business creation and environment articulate entrepreneur. This model consists of a set of actions or activities that aim to strengthen the entrepreneurial ecosystem. The research that led to the model took place in six stages: Characterization of North American Universities (Phase I); Ecosystem Analysis Entrepreneurs (Phase II); Research (Phase III); Development Model to Business Creation (Stage IV); Model Validation by Expert Panel (Stage V) and Settings (Stage VI). The first version of the model was based on the Babson Entrepreneurship Ecosystem Project, stimulus bill entrepreneurship, developed by Daniel Isenberg. The project unfolded in a model that shows that an environment to encourage entrepreneurship is not made up of only one element, but by a group of structures that working together strengthen this ecosystem. The initial model constructed by this research we used the six elements specified by Isenberg, namely: policies, financial resources, culture, supporting institutions, human capital and markets. The first version of the created model was then validated by the Expert Panel for Technical. The second version of the model, now validated - Model for Spin-offs Creation of Academic Based on Ecosystem Entrepreneurs - consists of three basic elements: the institutional arrangements, policies and entrepreneurial culture. The institutional arrangements are formed by agencies that facilitate technology development, the Technology Transfer Office (TTO), the Center for Entrepreneurship (CE), the Business School (BS), the Incubators and Science Parks (I / SP), the Junior Enterprise (EJ) and Entrepreneurs Network (RE). In addition to the institutional arrangements, the model is composed of other permeable layers, which are the policies that regulate the actions in this ecosystem and the entrepreneurial culture that disseminates the concept within the institution. Permeable layers are justified because they represent a border that information, knowledge and financial resources circulate between these elements that make up the entrepreneurial ecosystem and the external environment. And in that ecosystem also move new ventures. The model provides guidance in three of STI ripening stages: initial, intermediate and mature. The first STI fits into one of these stages and then uses the appropriate guidance to its stage.

This work aims, through an analysis of the Sartre’s pre-reflective cogito, verify how is implicit in the structures of the being-for-itself (consciousness) the presence to itself, the presence to the other (otherness) and the presence to the world. For this, will be explored some notions connected directly to the concept of consciousness, such as intentionality, human reality, image, ego, nihilation, being-in-itself, being-for-itself, being-for-other, among others, as well as how these concepts are engendered so arises, within the cogito itself, otherness and the world. In other words, how the circuit of ipseity, to say the very personhood, indicates the presence of the other and the world. For this, we shall discuss certain works of the early period of philosophical publications of Sartre, Situations I (especially the article on Husserl, titled A fundamental idea of phenomenology of Husserl: intentionality), The Transcendence of the Ego, The Imagination, The Imaginary and a few chapters of Being and Nothingness dealing with the issue which this study aims to investigate.

This work presents a new proposal of approach for proporcionality, whose focus is the Brazilian Elementary 7th grade student. This work is the record of a work of didactic engineeering that generated a sequence made by four didactic sessions. The main goal of this dissertation is to present ways for the student to determine, based on mathematical de_nitions, if two magnitudes are proportional and, in a_rmative case, if the relation is directly or inversely proportional. In order to do so, we propose the employment of a software called Geogebra as a teaching tool, to allow the integration with geometry, direct and inverse proportionality relations and practical experiments to assign a greater meaning to the presented content.

The object of this research is to work was analyze the spending cof individuals that consume goods and educational services, and school performance. The comparison of these two quantities was motivated by the expectations created by individuals in the acquisition of the such good in relation to the pursuit of their economic product that according Buckhan and Hannun (2001), is defined by mobility, occupational status and income. The product happens from the evolution of the individual through the gain or technical, academic and knowledge improvement, based on theories such as human capital (Schultz, 1973), market segmentation (Doering and Piore, 1971) and reproduction (Bordieu, 1978). From the empirical theories surveyed by Pinheiro and Fontoura (2007), Carvalho and Kassouf (2008), Santana and Menezes (2008), among others, which analyzed characteristics of individual or the individual’s families such as gender, color, inclusion of elderly, the and size of families that have influenced the distribution of funds for allocation of expenses and, indirectly, the expectations. In this context, a model for the evaluation of these characteristics associated with per capita income over expenditure using data from the Consumer Expenditure Survey (POF) was built. The model showed that the characteristics affect the educational spendings. The POF data about the expenditure data were compared to the data of educational performance of the tests conducted by the National Institute for Research Studies (INEP) such as Prova Brasil and ENEM, by geography region. The data for this comparsion showed similarities between five of six possible comparisons in relation to the Brazil average. These similarities may indicate in order to answers that satisfy the expectations of the individuals about educational products

SILVA, R.M. “Only the Strong Win”: The Hazing Barbarism in Agricultural Education. Dissertation (Doctorate in Education) - Programa de Pós-Graduação em Educação da UFSCar, Federal University of São Carlos, São Carlos, 2015. Traditional hazing practices in educational institutions date back to the 15th century in the first European universities and continue to the contemporary college hazing. Through literature review, gaps have been pointed related to this subject in the context of Brazilian agricultural schools. Adorno state that to “fight barbarism", hazing used in the German holocaust should be avoided. Based on this perspective, this research discusses the revival of the Nazi-fascist authoritarian personality nowadays. The research hypothesis is that the institutional culture medium in an agricultural school supports hazing barbarism. This study aimed to analyze the traditional hazing in the former Colégio Agrícola de Uberlândia (Agricultural College of Uberlândia) from 1969 to 1985, investigate the relations between institutional culture, hazing and the development of students' subjectivity in a hazing context. Therefore, the theoretical ground and discussions were based on the writings of Adorno, Horkheimer and collaborators about the "Authoritarian Personality Syndrome" and on Adorno's and Freud’s sociological works. The research methodology consisted of the semistructured interview with 10 participants. Empirical data were compared with the theory. The hypothesis was confirmed: the culture medium of Colégio Agrícola carries features that supports hazing. Five categories were applied to the interviews. The data were submitted to content and document analysis. It was observed that a committee consisted of students and public servants institutionalized hazing. Traditional hazing such as nicknaming and mud bathing were pointed. Due to hazing violence that resulted in some serious injuries, the hazing committee was disbanded in 1983. The institutionalized hazing expressed prejudices and the thinking of the ticket, by means of group exclusions and derogatory nicknames. The culture of machismo was detected in the viewpoint of student and hazing, masculine institutions. The Freudian ground to the concept of mass based the evidence that the student leaders were the ablest to conduct hazing; however, their involvement was reinforced by hazing institutional elements. The academic community was divided into segments in the context of hazing, but on the in general it was widely institutionalized. The conclusion is that hazing was an institutional phenomenon in Colégio Agricola de Uberlandia. Furthermore, hazing served students as a training for academic life and job market, by means of Taylorist and Fordist Technical Education. Hazing, courses and the teaching and learning processes of Technical Education during the time range under consideration was in compliance with military principles. In the last stage of this research, a CPI (Parliamentary Inquiry Commission) set up to investigate hazing in São Paulo universities revealed injuries and sexual abuses. To definitely stop hazing, it depends on a change in mind of students and leaders who disseminate prejudice and barbarism. Thus, the idea that "only the strong win", that shapes the human subjectivity and supports the hazing practices in the Technical Education, must be understood and immediately fought.

Peroxiredoxins (Prx) are antioxidant proteins capable of decomposing a variety of hydroperoxide are very abundant in the cell and in eukaryotes are distributed in many cell compartments. The Prx are able to reduce their substrates using a highly reactive cysteine residue, named peroxidatic cysteine (CP-S-), which is maintained in the thiolate form as a consequence of the active site environment. In hydroperoxide decomposition process the CP is oxidized to cysteine sulfenic acid (CP-SOH). These vast majorities of these proteins are obligate dimers and has a second cysteine involved in the catalytic cycle, named resolution cysteine (CR), which forms a disulfide with CP and is often reduced by the enzyme thioredoxin (Trx). In addition to the reduction of Prx, the Trx are involved in several other biological processes such as cell growth, inhibition of apoptosis, transcriptional activation and DNA synthesis. When cell are exposed to oxidative stress, the CP can suffer overoxidation, forming species such as cysteine sulfinic acid (CP-SO2H) and cysteine sulfonic acid (CP-SO2H), which are not reduced by Trx. However, the CP overoxidation results in a change of the of Prx quaternary structure, resulting in the formation of high molecular weight structures (HMW) with molecular chaperone property and related to signal transduction triggered by hydroperoxides. Saccharomyces cerevisiae, have two isoforms of cytosolic Prx (Tsa1 and Tsa2), which shares high similarity (86% identity and 96% similarity), but differ in cellular abundance and expression levels. However, these enzymes are often considered redundant proteins. This study aimed the comparative analysis searching for functional and structural differences between Tsa1 and Tsa2. We evaluated Tsa1 and Tsa2 relationships with its oxidizing (hydroperoxide) and reducing substrates (Trx1 and Trx2). We also performed structural and kinetic analysis showed a significant relationship between maintaining the decameric structure the activity of enzymes which occurs by a series polar interactions but not equal to the active site amino acids. Highlighting the Thr44 of Tsa1 (Ser in Tsa2) which is involved in decamer structure stabilization by a CH-π interaction type with the Tyr77 and through the Oγ atom (from Thr) polar interactions with Phe45 and Leu41. Overoxidation susceptibility assays were performed using Tsa1 and Tsa2, and our results revealed that organic hydroperoxides were able to promote the CP overoxidation more efficiently when compared to H2O2. In turn, Tsa2 was very more resistant to CP overoxidation than Tsa1. This difference was also investigated concerning the catalytic triad Thr (Tsa1) to Ser (Tsa2). We generated mutants carrying reciprocal substitutions Tsa1T44S and Tsa2S44T and our results revealed that Tsa1T44S become more resistant to CP overoxidation and Tsa2S44T become more sensitive. The formation of high molecular weight structures (HMW) of Tsa1, Tsa2 and mutants were also investigated by size exclusion chromatography (SEC) and transmission electron microscopy (TEM). The Tsa1, Tsa2 and mutants HMW formation were analyzed by size exclusion chromatograph (SEC) and transmission electron microscopy (TEM). The results showed an increase of HMW formation after Trx system reaction using high concentrations of CHP. Were observed the stacking of the ring-shaped structures besides spherical species. Our results demonstrate that Tsa1 and Tsa2 proteins differ significantly in overoxidation susceptibility and HMW complex formation, indicating that these proteins have not redundant biological roles and small changes in active site promote high functional and structural changes in these enzymes.

The main aim of this work is to develop alternative queuing models to M/ G/l, in which arrivals follow a Poisson process, the total number of customers on the system and the total number of service channels are unknown. Our interest is just to observe the service channel that will offer the maximum or minimum service time. Wherefore, the service distributions are obtained from the composition of the Conwav-Maxwell-Poisson distribution truncated at zero, used to model the number of service channels, with the general distribution to the maximum and minimum service time. Thus, we obtain new distributions for service time, which are called Maximum-Conwav-Maxwell-Poisson-general, denoted by MAXCOMPG distribution, and Minimum-Conwav-Maxwell-Poisson-general, denoted by MINCOMPG distribution, consequently, we obtain the queue models M/MAXCOMPG/1 and M/MINCOMPG/ 1, respectively. As general distributions, we use the distributions exponential, Weibull and Birnbaum Saunders, To illustrate the proposed queue models, a simulation study is done and also real data are used.

In recent decades, the lead time reduction has become crucial to ensure the competition of enterprises. To address this, plus the abandonment of the tradit ional mindset based on efficiency and cost, to a mentality based on the reduction of lead time, companies began to incorporate in production management, principles and practices related, outstandingly, to the Quick Response Manufacturing (QRM) and the Lean Manufacturing (LM). In this context, this work aims, according to companies located in Brazil, Europe, and in the USA: (I) Verify if the degree of knowledge of the exclusive principles of QRM approach is equal to the degree of knowledge regarding common concepts to LM and QRM, (II) Verify if the degree of knowledge of the exclusive principles of QRM is greater due to factors such as training, dissemination, and awareness, (III) Check if the mindset based on economies of scale and cost reduction is still the main obstacle in the degree of knowledge of the companies surveyed, (IV) Verify if the concepts / elements / exclusive practices QRM less adopted by companies are those related to the change of economies of scale and cost-based mindset, still fairly entrenched in enterprises, (V) Verify if there is a significant difference between the degree of implementation of QRM practices due to the region studied, and (VI) Check whether the use of concepts / elements / practices of LM favors the adoption of QRM. For this, it was carried out an exploratory survey with an intentional sample of companies in these regions who wish to reduce the lead time. Data were analyzed using descriptive statistics and non-parametric tests. Concerning to the knowledge of the companies surveyed about the QRM, it was concluded that the level of knowledge about the exclusive practices of QRM is lower than in relation to the common practice at LM and QRM. The companies’ knowledge degree about the exclusive principles of QRM is possibly greater due to training, dissemination, and awareness and such factors are present more at the region of US. The mindset based on economies of scale and cost reduction is possibly the main barrier in the degree of knowledge in the companies surveyed. Concerning to the application of the QRM practices by companies surveyed, it was concluded that the extent of implementation of practices regarding the key concept "power of time" is lower than the other key concepts; there was not observed any statistically significant differences in the degree of implementation of QRM practices due to the region; the LM practices helps and contribute to the effort of implementation of QRM in companies that seek to reduce the lead time and; the concepts, elements and practices of QRM less adopted by companies are those related to the abandonment of the mindset based on economies of scale and cost reduction.

The increase in the consumer electronics equipment, especially, the cell has aroused the academia and society in general interest. Such equipment when obsolete became part of the so-called junk mail. Among the components of this type of waste, are the printed circuit boards (PCB’s). The concentration of toxic elements such as Cd, Cr and Pb these PCB has proved high. Because of this situation becomes important to develop analytical methodologies for evaluation of these dangerous elements in PCB. Among the analytical techniques available, the most used in the determination of these elements has been the ICP OES. The evaluation of samples PCB by ICP OES performed in this study revealed that in addition to the regulated elements by RoHS (Cd, Cr and Pb), are present in high quantities, the elements Ba (2% w/w) and As (400 mg/kg). The Cu element was the one with the highest levels of concentration in some samples amounted to 35% (m/m). The use of a multivariate analysis such as PCA, showed some correlation between certain elements of the PCB. This is observed for the elements Ba and Ni, and also to the As, Cr and Fe. Alternatively to the use of techniques that require a pretreatment of the samples comes LIBS. The obtained emission spectra provided important information about the composition of these PCB’s. An analysis of the spectra reveals the presence of emission lines of elements such as Ba, Cd, Pb, Ni, Cu, Fe, Sb, among others. The elements that provide the most intense emission lines were Cu and Ba. Based on the obtained reference concentration by ICP OES and the values of the area and intensity of the spectra obtained, the construction of multivariate calibration models has been proposed. Employing MLR was possible to build the multivariate calibration models for elements of interest. However, due to lack of verified correction, among the area parameters, maximum intensity and reference concentrations, the proposed models are considered viable. However, the use of LIBS for characterization purposes samples for the presence of an element, shown to be feasible from a qualitative point of view.
