Bioactive glasses were developed by Hench in 1969, and are widely known to have the ability to rapidly form a chemical bond with hard and soft living tissues. Currently, these glasses have been used clinically as biomaterials that act in bone regeneration in dental and orthopedic applications. However, their use is still very limited due to their fragility and also the limited commercially available forms, such as powders and granules. Therefore, the development of processes that make possible their conformation in fibers and fabrics (meshes) is indeed promising and highly desired, as this new shape could significantly expand the usage spectrum of this excellent biomaterial. Thus, this project aimed to develop and improve the production of highly bioactive glass fibers by the downdrawing process, as well as optimize the production of unwoven fabrics and characterize them in relation to their physicochemical and biological properties. Therefore, a new bioactive glass composition previously developed at the Vitreous Materials Laboratory was used (LaMaV - UFSCar). This new bioactive glass presents a fast interaction with the body fluids to rapidly promote the healing process and reduced crystallization tendency for its processing into fibers, as crystal formation difficult or even impossible to obtain the same. The obtained results showed that this new bioactive glass composition is more suitable to undergo through working processes involving high temperatures than other currently known bioactive glasses, being then, possible to produce highly flexible fabrics and meshes by the downdrawing process. Concurrently, this new biomaterial presents similar physical-chemical and biological properties to gold standard bioglass 45S5, making this new biomaterial suitable for several applications aiming in situ tissue regeneration.

The present work is based on the literature related to the Bi2Se3 compound, which is present in current researches as a topological insulator and is also well known for thermoelectricity applications. In this work the electrochemical synthesis of a material containing Bi, Se and X (X = Cu, Fe or Co) was carried out searching for a composition of Bi and Se in accordance with the stoichiometry of Bi2Se3. The third element, X, was used in the electrodeposition baths considering the Bi2Se3 literature, which presents doping and interaction with other elements for this compound. The synthesis conditions were determined based on studies using cyclic voltammetry. The main material studied was the ternary compound containing Bi, Se and Cu. The films obtained were characterized using scanning electron microscopy, energy dispersive x-ray spectroscopy, x-ray diffraction and Raman spectroscopy. It was found out that baths containing sulfuric acid were adequate for obtaining films of Bi, Se and Cu but a bath containing glycerol and sodium citrate was necessary for including Fe on the material. Some magnetic properties of the films obtained were also studied and paramagnetic behaviour was observed for the samples.

Burn injuries represent a high risk of morbidity and mortality worldwide. In severe and deep injuries, the wound healing process is complex and requires the participation of different types of cells. Among the existing treatments, biomaterials and LLLT are highlighted for having properties that favor and stimulate the healing process. Thus, three studies were conducted to evaluate the effects of bacterial cellulose membranes in its pure state or enriched with lidocaine and LLLT (660 nm) in two different fluences (12.5J/cm2 and 25J/cm2) used independently or associated, on third-degree burns in rats. The burn was induced with an aluminum plate at 150°C, pressed onto the animal's back for 10 seconds. In the first study the action of bacterial cellulose membrane in its pure state and enriched with lidocaine, as biological dressings was evaluated. Therefore, the rats were divided in three experimental groups, CG (control group), MG (group treated with the pure bacterial cellulose membrane), and MLG (group treated with the bacterial cellulose membrane with lidocaine). The treated groups showed an advanced wound healing when compared to the control group. In the immunohystochemical analysis of COX-2, the treated groups showed a light immunoexpression, with the characteristics of repaired tissue. Thus, bacterial cellulose-based biological dressings were effective and provided a favorable environment for the development of the healing process. In the second study, the effects of LLLT with two different fluences (12.5J/cm2 and 25J/cm2) in three experimental groups, divided into CG (control group), LG12.5 (burning treated group 12.5 J/cm2) and LG25 (burn group treated with 25 J/cm2) were evaluated. The animals received laser application immediately after the induction of the lesion and the subsequent doses 2, 4, 6 and 8 days after the induction, at five different points, four on the edges of the wound and one in the central region. The LG25 had better results, with higher number of blood vessels, increased immunoexpression of VEGF (Vascular Endothelial Growth Factor) and decreased immunoexpression of COX-2 (Cyclooxygenase-2) when compared to CG and GL12.5 groups. The LG12.5 showed the longest delay in the progression of the healing process, due to its intense inflammation and tissue fibrosis when compared to CG and LG25. In the third study the association of pure bacterial cellulose membrane and LLLT (660 nm, 25 J/cm2) was investigated. Four groups were evaluated, CG (control group), MG (burn group treated with pure bacterial cellulose membrane), LG (burn group treated with laser 25 J/cm2) and MG + L (burn group treated with bacterial cellulose membrane + LLLT). Histological findings demonstrated that the treated group showed better results in the healing process. The (GM + L) showed results similar to those found in the GL, evidencing the stimulatory effects of angiogenesis provided by the laser light. GM showed improvement in the healing process, indicating the proliferative phase. However, although LLLT presented the expected proinflam matory effects, which modulate the inflammatory phase and favor tissue regeneration, the isolated action of the bacterial cellulose membrane proved to be advantageous by presenting tissue characteristics, which are compatible with a more advanced phase of the healing process.

The term interculturality is increasingly in evidence in the studies focusing mainly on the educational, political, economic and social contexts. Therefore, also in the field of foreign language teaching and learning, there are many works based on intercultural issues (Byram, 2000; Fantini, 2000; Mendes, 2004). However, it is possible to identify different approaches, and one of them which often stands out in discussions of the area is related to intercultural (communicative) competence. In this work we aim to develop a reflection on the relationship between the terms communicative competence and interculturality, in order to understand the potential uses of the term intercultural (communicative) competence and its implications, and to identify possible referrals for understanding the term interculturality in context of language teaching and learning. This Applied Linguistics research is characterized as a bibliographical, interdisciplinary and qualitative-interpretative based study. Through this research, we could understand more deeply ideas as competence, intercultural (communicative) competence and interculturality, and we have critically approached the relationship that has been established between these terms in the field of foreign language teaching and learning, especially in the context of Portuguese as a foreign/ second language. We believe that the discussions that bring out the notion of interculturality are symptoms of a society that aims to build a common horizon, so that the otherness can have its free space of expression assured. We understand, therefore, that intercultural issues should not be restricted to the level of skills/ competences in the practice of foreign language teaching. Interculturality could be understood as an invitation to reflection and action committed to the difference and the (co)experiences that take place inside and outside the classroom; a kind of driving force able to assist and guide teachers in their pedagogical planning, in the approach adopted by them to develop the communicative competence of their students, as well as in their attempt to raise students' and the other agents' awareness in the learning process for a careful and respectful attitude towards the “other”.

La recherche visait à analyser dans quelle mesure les femmes insertion dans'S pêche professionnelle dans les changements Amazon et les influences de l'activité quotidienne des pêcheurs artisanaux de Barreirinha (Amazonas). Il a cherché à comprendre comment l'exercice de la pêche professionnelle interfère avec les dimensions matérielles et symboliques des relations entre les sexes au travail; dans les relations avec les instances organisatrices des pêcheurs; et, par rapport au bénéfice de l'assurance-chômage Fisherman Artisanal (PDSA). Nous émettons l'hypothèse que l'SDPA change les rôles sociaux, de fournir un avantage pour les pêcheurs artisanaux. La politique a conduit les femmes à se joindre à la colonie de pêcheurs (Z-45), afin d'avoir accès à la prestation, sans toutefois modifier les fondements de la famille de l'homme en tant que fournisseur. La méthodologie, nous avons choisi la recherche qualitative, dont les entretiens et la recherche du lieu d'observations directes ont été formés en techniques indispensables à connaître, audelà de la pratique de la pêche quotidienne, les relations entre les sexes et la démystification de mythe Panema, selon le que la femme apporterait un état de jeu, de se livrer à la pêche. Cependant, la recherche a conclu que la femme toujours pêché, et avec la mise en oeuvre de SDPA intérieure, à condition que la reconnaissance professionnelle conduisant elle à surmonter les mythes et prouver que, en même temps que la figure masculine peut être un pêcheuse professionnel et fournisseur de unité familiale.

The use of amorphous metals becomes a large market in the industry of micro-components and/or milimetric machine parts, presenting excellent magnetic and mechanical properties and high glass forming ability such as the recent developed iron based alloys in the [(FexCo1-x)0.75B0.2Si0.05]96Nb4 compositions, where x = 0.1-0.5 at.%. Wherever, these properties are reached when this material is processed by techniques that impose and maintain higher cooling rates (103-106 K/s), limiting factors in order to obtain amorphous parts with centimeters in dimension. In this study, the Fe43.2Co28.8B19.2Si4.8Nb4 alloy was processed by spray forming as an alternative route to obtain amorphous deposits with large sizes. The study conducted depositions onto rotating copper rollers generating a co-lamination condition, producing larger ribbons. In a second step, depositions in industrial scale were performed using preheated cylindrical and flat substrates moving longitudinally at various speeds, producing deposits with different thickness. In a third deposition, subsequent layers were deposited due the came and back longitudinal movement of the cylindrical substrate. The microstructure of all materials were evaluated by optical and scanning electron microscopy, differential scanning calorimetry, and X-ray diffraction. The powders of all experiments and the spray-co-laminated ribbons presented fully amorphous microstructure. The first and second deposits exhibited a 1 to 2.5 mm thickness amorphous layer formed in direct contact with the substrate. The median/central regions (10 to 15 mm thickness) presented a mix of crystalline and amorphous phases or fully crystalline microstructure depending the thickness of the deposit. The third deposit was formed by ~10 layers with ~2 mm thickness each presenting fully amorphous or a mix of crystalline and amorphous phases. These results suggesting that this process is a promising potential for the production of amorphous alloys in large volumes and sizes, expanding the use of these materials.

The National Curricular Guidelines (DCN) of the 2002 Dentistry Undergraduate course are guidelines to be observed in curricular organization that must be necessarily adopted by all higher education institutions (HEI). The overall objective of this study was to analyze the pedagogical projects of the courses (PPC) Dental Public Universities of the State of São Paulo (SP) in the light of DCN. This research is qualitative. The study subjects were five dental courses of SP who had their PPC reformulated after the DCN. The first collection of information was through secondary data obtained from the PPS of each educational institution. The documentary analysis of PPC courses was held in the light of DCN for graduation in dentistry and PPC courses were analyzed using an array of analytical categories. The eight analytical categories used in the analysis of PPC were divided into two areas: 1. Professional profile (general profile, health care, health management and health education) and 2 Course structure (organization of the course, design of teaching learning, teaching methods and learning and assessment). The second source of information consisted of primary data collected through semi-structured interview with the five coordinators of the courses, defined as the study subjects. The semi- structured interviews were conducted in person with three coordinators and through Skype with two coordinators of the courses, and were composed of questions about PPC and student education from the perspective of DCN and acting for the NHS. Qualitative analysis of the interviews took place from the content analysis technique, thematic modality defined by Bardin. The analysis of PPC in the light of DCN demonstrated suitability in general, with some observations regarding verbatim parts of the DCN in PPC, not matching the reality of course, little detail in relation to health management at all PPC analyzed and teaching methodologies learning and assessment still on traditional modes of education in relation to the powers described in DCN.

Brazil is the world’s second largest producer and exporter of bovine fresh meat, what in 2014 accounted for about US$23.31 billion in Gross Value of Production (GVP) in a market of US$62.97 billion per year, generating about 7 million jobs. The most evaluated parameters about meat, can be divided into physical-chemical like temperature (T), water activity (Aw), redox potential (Eh), hydrogen ion potential (pH), maturation or tenderization, cooking method and sensorial like color, softness, texture, juiciness and flavor - combination of aroma and taste. As 75% of muscle composition is water, in the muscle conversion into meat there is a release of 2 to 5% of this total water, due evaporation and exudation, characterizing a high Aw value. This obtained solution is rich in amino acids, peptides, nucleotides, sugars and although the vacuum packaging is considered an efficient way to preserve in natura chilled beef, a serious problem, known as blown pack may occur if microbial contamination is significant or not respect the cooling minimum temperature (4 ± 2 °C). Therefore, the reduction of microbial proliferation in food is necessary. The goal of this work was to use a coating based on chitosan at 1% (w/w) and glycerol at 0.5% (w/w) which can be applied to food protection, especially as edible films and coatings. In parallel, was evaluated the effects of extract (PEE) and propolis nanoparticles (PNs) on some bacterial genders commonly found in fresh meat in natura. The permeability of the film produced in this work, respectively to O2 and CO2 gases was 1.53 ± 0.73 • 10-15 g•m•(Pa•s•m2) -1 and 1.20 ± 0.06 • 10-12 g•m•(Pa•s•m2) -1, relatively larger, when compared to literature. This film has relatively high moisture content and low solubility, what is interesting for application in meat, because it keeps its barrier property and integrity, even under high humidity and possible high Aw. Regarding the color (Hue) of meat samples (Longissimus dorsi) used in this experiments, on the 7th day presented a small disadvantage of coated and vacuum samples relative to that were not vacuum. However, on the 14th day, brightness (Chroma) of the samples in this condition was better than the other samples and, there was no significant difference in color. Therefore, this condition yet can be considered more advantageous when we wish to extend the shelf life time. The coating developed in this work, improved water holding capacity (WHC) of meat samples, which helps the desired juiciness of the product. Besides that, this film inhibits the growth of enterobacteria, lactic acid bacteria (LABs) and total psychrotrophic, which certainly can increase the shelf life of the product. The used PEE has a relatively high phenolic content and antioxidant capacity. For all tested concentrations of PEE and PNs with all bacterial species, better results were obtained with PNs.

Brazil is characterized as an essentially urban country, because more than 80% of the population lives in cities. By the end of the 20 th century, the Brazilian cities, mainly the large and medium ones, started to face problems of difficult solution as a consequence of the overpopulation in the urban centers. Urban centers, which usually shelter the historical and cultural heritage of the city, in other words, its memory, today is constituted by run down areas, harboring slums, deteriorated buildings, decadent commerce, among other problems that intensify the deconstruction of this space. The Statute of the City serves to equip the municipal districts, so that these can develop and execute their urban policies assuring the right to the sustainable city, which involves, among others, the protection, preservation and recovery of the environment as well as of the historical, cultural and landscape heritage. The present study analyzes how the partnership involving the government, the private sector and the estate owners, interacting with each other, destined for the users and the community, can revert the process of degradation of the historical centers through the “Alegra Centro” program, currently on the way in the city of Santos. This study can still be a contribution to revitalization programs of port areas.

This study aimed to contribute to the understanding of the dynamics of water resources in the watershed of Sorocaba river and establish relationships between availability and water demand. Initially it was proposed a quantitative model of how to distribute the water in the different stages of the water cycle, from the moment of the rains, to flow to your river mouth, considering the intermediate steps between these two events, including human interventions represented by withdrawals of water from springs. For it was carried out the survey and analysis of hydrological data available and estimated those without measurements through the water balance. Set up for the series evaluated the climatological normal temperatures and rainfall and the average flow rate in river mouth, ie the watercourse that is base level of the watershed. The following parameters were estimated: potential and real evapotranspiration, surplus and water deficit. The average rainfall in the basin for the period 2006-2012 was 1,337 mm.year-1 , the average annual temperature 21.2°C, the ETP and ETR 1,011 mm.year-1 and 999 mm.year-1 , respectively, the water surplus 338 mm.year-1 , the average flow in river mouth 360 mm.year-1 and the flow derived and actually consumed by the users of 16 mm.year-1 . The water availability was adopted as the flow with 95% permanence (Q95%), estimated at 24.1 m3 .s-1 and the demands were obtained based on data from granting processes and by other methodologies, enabling a comparison between the results. Demands for major consumptive uses identified in the watershed were calculated with the following results: human supply 6.20 m 3 .s-1 ; industrial 1.83 m 3 .s-1 ; irrigation 3.59 m 3 .s-1 ; and animal consumption 0.24 m 3 .s-1 . The relationship between availability versus demand was considered and the results allowed indicate that the current situation of water resources across its use is very critical.

This research, elaborated from theoretical grounds in the area of design and ergonomics, has as its object of study an improvement project implemented in a producer of cellulosic fiber packaging (molded pulp) for packaging eggs and fruit, located inside the State of São Paulo. This project aimed to improve the operation conditions of the workers who took care of finishing activities at the apple trays production line. The research question is to discuss how the use of the Ergonomics concepts in the development of workspace design projects can help to prevent against new constrains on the development of activities. Specifically, it seeks to highlight the need of using tools that provide to the design process deep details about the activities involved in carrying out the tasks of the workspace where the improvement project will be implemented. Considering that the Ergonomics in workspace design can contribute for the collective construction to solve problems related to work reducing the probability of new constraints following the implementation of the project. It was used the approach of Situated Ergonomics, the Future of Activity Analysis and the method of Ergonomic Work Analysis. The obtained results showed that the design process used was not built with the effective participation of the users and the interaction between the actors involved in the operation lacked from an important knowledge about “how to do” of the operation. It was observed that the new situation brought difficulties in the development of activity as well as the creation of new constrains. It was concluded that the Ergonomics applied in the development of projects promotes the collective construction between the different actors in the process, resulting in a deep detail of the activities involved to develop the tasks and, as a consequence, better information being possible to design systems that meet the workers needs.

How a brazilian viola come to its existence inside an artisan and manufacture environment? The materials allocated in such environment of craft arrange under specific conditions variable routes for one task: the precise and risky establishment of material compatibility degrees in each technical circumstance. When contouring the artisan and manufacture environment the object viola refracts the discourses about its existence in favor of the resources which assure its well defined boundaries. Whatever the discourses about the web-frames of that craft surrounding, it is through its functional inboard where the technical activity exposes its irreducibles: the technically articulated resources. A craft environment from Sao Paulo’s countryside thus assign to this research a problem of Comparative Technology, limiting this research to a focal descriptive procedure as a methodological experiment guided by rhytms of construction and repair of brazilian violas inside the craft environment – as far stand its instruments, tools, machinery and products. The frame of this Comparative Technology study is the processes of internal compatibility of a craft environment: the object viola is a process, a topical serie able to reconfiguration.

The research is linked with the Education StrictuSensu Post-Graduation Program of UFSCar – Sorocaba and started with the participation in a group of homosexual/transgenderparents that used to arrange meetings of mutual help to fight against homophobia in the family context, the GPH, that has been established as a public policy in Sorocaba-SP since April/2013. The investigation was takento find out the limits and possibilities of this homophobia combat space through the presentation and analysis of categories and social conventions that merge there. From the theoretical field of gender and post-structuralistsexuality, it was sought to investigate the relations between families and homosexual/transgender, particularly the lives of the parents with the objective of comprehending and integrating their children. Because learning and investigating this relationship space is a process that cannot be measured to quantifiable variables, this research is qualitative. The methodological work was accomplished through the bibliographical research of documents and field studies, using the following procedures: documental analysis, interviews, prioritizing the participating observation and speech quantitative analysis in the perspective of events that took place in the maternity. The most difficult elements of this journey is the binary speech inheritance – man/woman, male/female, straight/homo – produced and reproduced daily inside the homophobic speech as in those that in some way are favorable to gender diversity and sexual orientation. The difficulties felt and supposedly faced by the GPH parents and the categories and social conventions mobilized in this journey were considered to be linked to differences built – social and culturally – translated in power relationships that rank gender, rendering inferior all forms that do not correspond to the linearity of sex, gender, desire and sexual practice. The implementation and participation at the GPH Sorocaba shown, not only the strength of heteronormativity, but also that the different fugitive form of being and living the genders and sexualities, generally not accepted but tolerated, highlighting that there is no social convention detachment in this context. At the same time, the attribution of new senses, the questioning of built “truths” that, for a long time, were naturalized and reproduced by these LGBT parents shows that public policies aimed to homophobic confrontation in family context have an important role to mitigate it.

Green Photochemistry: Development of transition metal complexes for activation of luminescent singlet oxygen and its application in the disinfection of wastewaters contaminated with pathogenic microorganisms (Escherichia coli and Enterococcus faecalis). The development of the perylenes derivatives complexes Ru (II) and Re (I) has received increasing attention in energy transfer. Here in we investigated, the synthesis, characterization, energy transfer studies and biological testing of three complexes of Ru (II) and Re (I) cis-RuCl2(PDI1)2, cis-RuCl2(1,10- phen)(PDI1 ), fac-[Re(CO)3(PDI1)Br] and [Ru(1,10-phen)2(PDI2)]2+. The complexes are simple and stable preparation of both solid as well as DMSO solution (in the absence and presence of light) and are resistant to hydrolysis at pH 4 to 8. All compounds were characterized by 1H NMR, IV, elemental analysis and theoretical calculations whose results were consistent with the proposed structural. The complexes exhibit intense absorption in the visible region (500 nm, ε = 20,000 mol-1Lcm-1) and an intense band emission around 600nm, long emission lifetime 500 nsec and a small Stokes shift (600 cm-1), consistent with the rigid structure of the perylene chromophore. We observed that some complexes have paramagnetism ability in the ground state and both solution and on solid medium which was confirmed by RPE and theoretical calculation. These complexes were not able to produce photochemical 1O2. However, [Ru(1,10-phen)2(PDI2)]2+ presented photochemical generation of 1O2 dissolved in methanol, ethanol, acetone and acetonitrile and quantum yield of the formation of this species (Φ1O2) in order 0.30. Thus, we immobilize this complex on silica gel functionalized with aminopropyl group and it produced 1O2 with Φ1O2 around 0.20. The ability microbicide of these complexes were tested against the yeast Candida and values obtained show they are toxic for these microorganisms.

Agile development principles ensure that continuous attention to technical excellence combined with a good design contributes to increased agility ensuring products with higher quality. Usability is one of the quality attributes, and is related to making the experience enjoyable user through an efficient and intuitive interface design. Agile methods are committed to deliver valuable software to the satisfaction of the customer. At times, they deliver only the utility, without covering aspects of usability. Design solutions providing greater usability and more appropriate to the users’ context is the main concern of the Interaction Design (IxD). The IxD is based on user-centered design, which takes into account the users needs and wants, aiming to promote interaction more enjoyable experience. In recent years, the attention in integrating user-centered design practices into agile methodologies has increased. However, a very limited number of contributions have addressed the integration into a broader level, gathering practices and providing guidance to the organization of work within a software development roadmap. This dissertation presents an approach to integrate user interaction design into Scrum process through activities and artifacts. In the first stage of the study, a literature study was performed to determine possible strategies for integrating IxD into Scrum process. Furthermore, an action research approach was applied to define and evaluate the artifacts that would support the ScrumUX integration approach, closely with the professionals in the software development industry. In the second stage, an experimental study was carried out to evaluate the proposed ScrumUX integration compared to traditional Scrum approach. The experiment was carried out in an academic context, in which nineteen students divided into five teams worked in software development projects, in the ERP systems domain. Statistical tests confirmed a significant difference between the experimental and control groups, noting that the teams who used the ScrumUX approach produced software with better degree of usability in the task support perspective, considering ERP systems’ users opinion.

Poly(vinyl alcohol) - PVA is a high hydrophilic semicrystalline polymer which has excellent properties such as good chemical resistance and high biodegradability and biocompatibility. Due to its semi-crystalline nature, crystalline domains, under controlled conditions, may act as physical crosslinking points, while maintaining the integrity of the structure under swelling. This feature makes PVA hydrogels promising for the development of drug, or other bioactive substances, delivery systems. Another interesting feature of this kind of hydrogels is the ability to form high stable network from crystalline domains formed through freezing and thawing cycles. This method shows the formation of crystallites which act as physical crosslinks while maintaining the insolubility of the material in water. Recently many studies show the use of nanostructures to improve mechanics properties and diffusional behavior of small molecules. Paromomycin is an aminoglycoside antibiotic widely used for cutaneous leishmaniasis therapeutics in Brazil. In the last years some studies have revealed that the patience adhesion to the treatments of cutaneous leishmaniasis with ointments form is low. Therefore hydrogels are an interesting alternative to the ointment forms. As the main objective of this work was the preparation and characterization of poly(vinyl alcohol) hydrogels containing sepiolite nanoparticles for the preliminary feasibility of using as controlled release system for paromomycin, hydrogels were prepared by cryogelation process. This ensures the formation of the hydrogel, as long as the crystalline domains formed during the PVA cycles act as crosslinking points, allowing the membranes water transport measurements of the drug in the presence of sepiolite. In this investigation membranes were characterized by differential calorimetry, thermogravimetry and X-ray diffraction. Furthermore polymer retention, swelling in simulated body fluid, hemocompatibility and drug delivery were studied to establish structure-properties correlations. The results show that cryogelation cycles significantly alter the swelling of the membranes; interactions polymer-nanoparticle increases the rigidity of the amorphous phase. Comparing to pure PVA hydrogels, in nanocomposites hydrogels the hemolysis decreased. Increasing the percentage of nanoparticles the membrane crystallinity decreases. The samples degradation profile, the thermal stability and drug delivery profile are not modified by the amount of nanoparticles incorporated.

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.
