The present research discusses the relations between leadership and organizational culture in the Brazilian public sector. The objective of the study was evaluate the effect of leadership on the organizational culture of thirteen agencies of the Instituto Nacional do Seguro Social (INSS) of the Araraquara administrative region, located in the interior of the State of São Paulo. The work was carried out through a survey, namely, a data collection for the accomplishment of a correlational study. For this purpose, two models of survey questionnaires for quantitative analysis were used: the Multifactor Leadership Questionnaire, developed by Bass and Avolio (1990), and the Competing Values Framework, produced by Cameron and Quinn (2006). The assertions of the questionnaires were adapted to the 5-point Likert scale. The questionnaires were applied to the organizational individuals of the agencies under study, obtaining a valid sample of 166 respondents, being 13 managers and 153 employees of the agencies teams surveyed. For the treatment of the data collected in the survey, descriptive and exploratory analyzes were carried out, using the partial least squares approach of the structural equation modeling method (HAIR; RINGLE; SARSTEDT, 2011). It was possible to validate the relationships identified between the leadership and organizational culture constructs in the INSS agencies of the Araraquara administrative region. The results demonstrate the predominance of the transformational leadership style (BURNS, 1978; BASS; AVOLIO, 1993) and the type of clan culture (CAMERON; QUINN, 2006), as well as the correlation between these two constructs as the one that most stood out among the several correlations present between leadership and organizational culture in the INSS agencies surveyed. Finally, it was possible to conclude that, in the perception of the respondents, leadership influences the culture of a public organization, through a positive correlation of high statistical significance (COHEN, 1992).

Several machine learning applications use classifiers as a way of quantifying the prevalence of positive class labels in a target dataset, a task named quantification. For instance, a naive way of determining what proportion of positive reviews about given product in the Facebook with no labeled reviews is to (i) train a classifier based on Google Shopping reviews to predict whether a user likes a product given its review, and then (ii) apply this classifier to Facebook posts about that product. Unfortunately, it is well known that such a two-step approach, named Classify and Count, fails because of data set shift, and thus several improvements have been recently proposed under an assumption named prior shift. However, these methods only explore the relationship between the covariates and the response via classifiers and none of them take advantage of the fact that one often has access to a few labeled samples in the target set. Moreover, the literature lacks in approaches that can handle a target population that varies with another covariate; for instance: How to accurately estimate how the proportion of new posts or new webpages in favor of a political candidate varies in time? We propose novel methods that fill these important gaps and compare them using both real and artificial datasets. Finally, we provide a theoretical analysis of the methods.

The Ecological-Economic Zoning (EEZ) formulation must, necessarily, be a participatory process, comprising the methodological adaptations according to the regional peculiarities. This research aimed to study, from the perspective of the participatory mapping, in three failed attempts of the Vale do Ribeira EEZ to formalize this legal instrument (1st period: from 1980 to 1998; 2nd period: from 1999 to 2005; 3rd period: from 2010 to 2014). The methodology was based on case study and content analysis, from four data sources: Geographic Database (GDB), Minutes of Meetings, Processed Documents and Interviews. Only documents and interventions directly related to the map were analyzed, discarding the conceptual and theoretical character ones. In the three periods, it was noted the existence of social participation strategies. In the first two periods, there was a predominance of participatory mapping based on cartographic (on paper), while in the third period, there was also participatory mapping with GIS Desktop. The minutes of 122 meetings and registrations of 191 geographical interventions were analyzed, most of them from the third period. A low processing of documents was observed, with a majority (65%) sent by the coordinating body of the EEZ. Regarding the records in the BDG, of the 1,495 existing polygons, 65.2% presented some description or justification of the framework. The approach of key actors with geotechnical tools is also important to evaluate the process as a whole, and not just the results. The evaluation showed that all forms of registration (meeting minutes, GDB and documentation) complement each other in the understanding of the process dynamics. Minutes of meetings are fundamental to record the conceptual discussions and details of the arguments that led to the decision making by the group, but they also make it difficult to retrieve the discussions in future meetings and to do the direct correlation with the map. On the other hand, the direct insertion in the attribute table during the discussion, proves to be effective both for the agility of the registry and for the subsequent rescue of the discussion. This study sought to demonstrate that there has been progress in the development of participatory techniques, but also to highlight the needs to improve the debate about these works’ methodologies and criteria. The approach of the stakeholders with geotechnology is also be seen as a positive result, since it brings empowerment and greater knowledge about the work. The use of GDB as a complementary method for the registration of participatory processes deserves to be improved, with the development of new techniques that allow the storage of the history of modifications made on the map.

In recent years, organocatalysed reactions have become an important field in asymmetric synthesis. Particularly, Michael addition reactions using various donors and acceptors have been explored to generate substrates that can be used as building blocks in other transformations. Chalcones, for example, are widely used as Michael acceptors not only because of their privileged reactivity but also due to their biological activities already reported. On the other hand, the α,α-dicyanoolefins proved to be a very versatile reagent, capable of acting as Michael acceptors as well as vinylogous nucleophiles in organocatalysed reactions. However, to date, the addition of α,α-dicyanoolefins to chalcones has not yet been explored. Considering the potential biological activity of the products, in this study, we report the use of a bifunctional catalyst derived from the alkaloid cinchona to perform the enantioselective addition of α,α-dicyanoolefins to chalcones. Based on preliminary results obtained in our research group, the Michael addition reaction was optimized by investigating time, acid additive, temperature, catalyst loading and solvent. Looking for more environmentally sustainable conditions, we have tested a series of greener solvents and the bio-derivative 2-MeTHF at 15 mol% of catalyst proved to be the best for this transformation. Having established the best reaction condition for this reaction, we investigated the scope and limitations of the developed protocol, where 17 new compounds were synthesized with yields in the range of 28-66% and 71-98% enantiomeric excesses. With the goal to increase the structural diversity, attempts to cyclize the Michael adducts were performed using different bases and acids.

This paper analyzes how the legal mechanisms for the education of people with disabilities in the National Constituent Assembly (ANC), 1987/1988, the historical moment that culminated in the Constitution of the Federative Republic of Brazil promulgation, on October 5th 1988, as well as the participation of people with disabilities and entities involved in public hearings in the Subcommittee of Black people, Indigenous Populations, People with Disabilities and Minorities, as well as the discussion on education in the Subcommittee on Education, Culture and Sports. The research was subdivided into four chapters: the first chapter is composed of the knowledge production, based on the research carried out using the keywords "Social Movements", "National Constituent Assembly" and "People with Disabilities" at Digital Databank of Thesis and Dissertations - BDTD, of the Brazilian Institute of Information in Science and Technology - IBICT; the second chapter dealt with the events during the civil-military dictatorship (1964/1965), the Brazilian Democratic Movement the performance in opposition to the Arena and the called by the Constituent; chapter three covers the end of the civil-military dictatorship, as well as the historical process that culminated in the indirect election of Tancredo Neves to president and José Sarney as vice president; the fourth chapter dealt with the civil Society profile that participated in the discussions on people with disabilities, its organization to elaborate the proposals presented at a public hearing in the Subcommittee on Blacks, Indigenous Populations, Disabled People and Minorities, in addition to the other constituent phases and works, with a view to articles aimed at the people with disabilities education and philanthropic institutions. As a research result, it was pointed out that many claims of people with disabilities were contemplated in the Constitutional text. It was found that the participation of Deputy Nelson de Carvalho Seixas influenced the process of some subjects for people with disabilities. It was noted the parliamentarians lack of knowledge about the proposals of these people discussed during the ANC, and that education became the right of everyone, the State and the family duty, as well as guaranteeing specialized educational service, preferably in the regular network of education.

The Edicaran period (635-541 Ma) was characterized by great changes on the planet, among them, important modifications on the biosphere. In this time interval there was a diversification of unicellular Eucarya, including their macroscopic forms. A representative of the Ediacara-Cambrian boundary is the fossil Corumbella werneri, scyphozoa, firstly described in the pellets of the Tamengo Formation. Corumbella werneri might have been one of the first animals capable of synthetising hard-parts, in a context in which active predation was still being stablished. Due to this, the work here presented, had as objectives: (1) to verify mineralogical and chemical composition of the carapace of Corumbella; (2) to investigate palaeoecological aspects of this organism; (3) To narrow the evolutionary affinities; (4) to ascertain the existence of other taxa associated. For this, it was used non-destructive techniques, such as MicroCT and spectroscopy, allied with petrography. Different intensities of calcite and kerogen were verified on the carapace of Corumbella, indicating a possibility of an organo-mineralized skeleton. Data about the taxonomy of Corumbella revealed that it is a sister-group of conulariids. As for the other components of the paleobiota of Tamengo Formation, microfossil studies showed ovoids structures and acritarches. These ovoids structures have been found associated with Corumbella specimens, and have been interpreted as a result of the interaction between microbial mats and the substract. For the acantomorphic acritarches, here described for the first time in a new locality of Tamengo Formation. They were characterized, mostly, as Bavlinella sp e Leiosphaeridia spp.. In an important way, the identification of acritarches strengthens biostratigraphic studies, which might stablish biozones for the Late Ediacara, in this unit. Therefore, this work presents new data which contribute both for the general knowledge about paleoecology and taxonomy, and generates new insights and questions that might be answered in future studies.

The present work presents a comparative study between different steel structures on shallow foundations (single footing) and deep foundation (piles) with the purpose of identify the effects of the consideration of the soil-structure interaction (SSI) on the structural analysis. The SSI consideration is a refinement of the structural analysis, currently allowed through the evolution of the computer science and where the deformability of the soil in the structural model is taken into account. In the literature are found several studies on the effects of SSI in the structural analysis regarding the structures of reinforced concrete, however for steel structures there is a need to deepen the studies. In this work 5 steel structures and their respective shallow and deep foundations were designed, where the number of floors was varied (4, 8, 12, 16 and 20 floors), and consequently the types of bracing. Initially the structures were analyzed considering the rigid support, then they were analyzed considering the deformability of the soil and the obtained results were compared to each other. For the SSI consideration, the Winkler Hypothesis was used, through the coefficients of reactions (vertical and horizontals). An application was developed in order to streamline the process of obtaining coefficients. Were analyzed the results of support reactions and bending moments at the base of the columns, global stability coefficients B2, lateral displacements and soil displacement. The results show that the axial compression forces, bending moments and soil displacements were not significant, possibly due to the lightness of the steel structures, since the lateral displacements show major changes due to the withdrawal of the rotation restriction of the support and consideration of the real rotation stiffness of the column-footing connection, the coefficients of global stability also suffered significant variations, where there were changes in the classification of the steel structure from small to medium displacement, which would imply different considerations in the structural analysis. The work carried out intends to initiate the studies of the SSI consideration in the analysis of the steel structures, thus improving the degree of refinement of the structural analysis.

The goal of this paper is to evaluate the implications of electoral justice activism in political-party competition by creating new law in this current republic. That is, although it is not within its competence, the TSE has been carrying out these functions, through new rules that, in turn, have implications both in the system of political representation, and in the relation of horizontal accountability and between the Powers of the Republic. We start from the premise that the model of electoral governance adopted in Brazil favors judicial activism through resolutions issued by the Superior Electoral Court, since such an independent and specialized model excludes political parties from managing the electoral process, making the production of consensus of political party competition is left to the TSE. Resolutions will be analyzed according to their origin, scope and political consequence in order to assess whether the Court has acted as a "legislative power" or have taken decisions of mere interpretive character in the light of the Federal Constitution. The hypothesis is that judicial activism of the Higher Electoral Court has been used as an instrument of horizontal accountability by the Judiciary, that is, control of the electoral and legislative action of the Executive and Legislative Branch, atypically by means of the creation of law in addition to its constitutional competence to regulate electoral matters.

Ex-situ conservation has become a common strategy, often used to save threatened species from extinction. However, captive animals are exposed to the risk of pathogenic transmission, both by domestic and wild free-living animals. This study aimed to sample free-lived wild birds found in bird enclosures in a zoo park in southeastern Brazil, assessing the risk of transmission of pathogens. We proceeded focal observations in all bird enclosures to identify the most visited ones and to study the behavior of visitors. We analyzed an interaction network to estimate the interactivity between free-living and captive animals. Next, we settled mist nets near the precincts with the highest frequency of visitation, to capture free-lived birds and collect biological samples. The network of interactions was represented by 14 visitor species and 10 visited enclosures. Passer domesticus and Columbina talpacoti were the most frequent visitors. Foraging on the ground and foraging on feeders were the most-frequent observed behaviors. The network presented low connectivity (26%) and a nested pattern (NODF = 53.39, p = 0). We captured 56 free-living birds from four species and collected 68 biological samples. Escherichia coli was the most frequently isolated agent (63.6%). Although enterobacteria were regularly identified in the collected samples, the impact of this relationship could not be directly measured. However, we have shown a latent risk of pathogen transmission, due to regularity and visit behavior of some free-lived bird species, which frequently host enterobacteria and intestinal parasites.

High Availability is the most important aspect when discussing resiliency over telecommunications systems in the context of the adoption of the cloud computing paradigm, a big challenge for telecommunications service providers. Initiatives of NFV platform implementations like OpenMANO (strongly based on NFV standardization from ETSI) serve as base to run experiments like the one proposed in this master project, in which we describe our contribution to an implementation of management for high availability on top of platform proposed by Open Source MANO (OSM). The high availability implementation presented in this project is adherent to ETSI standardization and contributes to one of the most important NFV frameworks that up to now has not presented support to such feature. In this project, we present an experimentation over OSM implementation which involves the whole environment with its technological complexity. In concrete terms, our contribution addresses two main aspects: a proposal for information modeling based on ETSI standardization on high availability and its implementation in the OSM framework. Such implementation consists in the detection of failure by the orchestrator implying in a network reconfiguration as a mechanism to support redundancy in an active-active scenario. The experiment was tested and evaluated in a real minimalist environment to demonstrate the implementation performed to manage high availability information and re-orchestrate data flows between redundant VNFs.

Angiogenesis, a process by which new capillaries are formed from pre-existing vasculature, is essential in both physiological and pathological conditions. Inadequate balance between pro and antiangiogenic factors can contribute to the progression of tumors and development of metastases. The αvβ3 integrin is considered an angiogenic regulatory receptor due to its cross-talk with vascular endothelial growth factor receptor 2 (VEGFR2). Understanding how these components functionally interact as angiogenic repressors is crucial for the identification of new therapeutic strategies. Disintegrins comprise a family of low molecular weight, cystein-rich peptides from snake venoms that specifically bind to integrins, inhibiting their functions. DisBa-01, a recombinant RGD (Arginine - Glycine - Aspartic acid)-disintegrin from Bothrops alternatus venom, has high affinity for αvβ3, exhibiting anti-metastatic and anti-angiogenic properties. However, its role in the cross-talk between β3 integrin and VEGFR2 in addition to its involvement in downstream signaling pathways, has not been explored. The present study has shown in vitro evidences regarding the direct association between DisBa-01 and the β3/VEGFR2 complex in human umbilical endothelial cells. DisBa-01 inhibited VEGF-induced viability, migration, invasion, adhesion to vitronectin and tubulogenesis, thus decreasing the angiogenic response. DisBa-01 treatment did not affect β3 expression, however, it decreased VEGFR2 protein expression. VEGF-mediated phosphorylation of both receptors was inhibited, causing downregulation of ERK1/2 and PI3K signaling pathways. DisBa-01 positively regulated FAK/Src/Paxillin downstream signal, affecting actin cytoskeleton reorganization, cell migration and adhesion. In conclusion, DisBa-01 impairs the β3/VEGFR2 cross-talk in HUVECs, which interferes in the signaling pathways of ERK1/2, PI3K, FAK, Src and Paxillin, resulting in anti-angiogenic action and cellular morphological alterations. Moreover, these results indicate a strong regulatory role of αvβ3 integrin on VEGF-induced angiogenesis.

Despite the historical exploitation and fragmentation of its native area, the Atlantic Forest still houses a significant diversity of wildlife species. Due to its importance for the maintenance of fauna representatives, getting knowledge of species diversity, and how they interact with each other and with the physical environment in strategic Atlantic Forest areas, is fundamental for effective species management and conservation plans. Thus, this study aimed to analyze the bat community from Carlos Botelho State Park (CBSP), a protected area with a high preserved Atlantic Forest and no ecological studies with bats until now. For this, we evaluated two aspects: (1) what is the influence of local altitude on bat abundance, species richness and diversity at CBSP and; (2) how the interaction network between bats and plants (flowers and fruits) is structured at the Park. In spite of varying considerably in abundance and species composition, species richness and alpha diversity of bats does not seem to be influenced by altitudinal variation found at CBSP area (1000 m). Measures of beta diversity indicate that the variation found in bat species composition between lower and higher altitude is driven more by species replacement between points (spatial turnover), than by orderly disaggregation of assemblages from the same species pool (nestedness). Through the analysis of a multilayer network of bat-plant interactions at CBSP, we found a nestedness pattern of interaction (NODF = 0.62, p < 0.0001) and few overlap on interactions between bats and flowers and bats and fruits. The results also showed that the bats A. geoffroyii, C. perspicillata and A. caudifer are central, acting as keystone species for the structure and maintenance of interaction network. In addition to filling an important knowledge gap for CBSP, by evaluating the bat species diversity in an area with no studies with bats until now, the results presented here reinforce the important of analyzing species diversity at spatial scales. Besides that, they help us to better understand the structure of bat-plant interaction networks in Atlantic Forests, and also which bat species are central to maintain these interactions. We suggest that more effective local conservation strategies should go beyond local diversity data, and also consider spatial variation and data on interactions between different species that comprise the natural systems.

Technical Intelligence and Information Quality are areas of knowledge that are important for decision making in the organizational context. Some challenges that deserve attention emerges when we approach both areas. First, in the up-to-date scenario of high volumes of data and information, the collectors are running information practices to facilitate the retrieval of accurate data and information for decision making. This goal aggravates when intelligence is direction of the functions for science and the technology, as is the Technical Intelligence. The tesis of this research is that tools, models, and methodologies, especially those used in the management and improvement of the quality process, manufactured products and services , also used by Quality of Information, can be applied to the process of Technical Intelligence to improve it. Although recent research points to the possibility of evaluating and improving Information Quality through methodologies used in Quality Management, these do not correlate directly with Technical Intelligence. The focus of the improvement was to optimize the levels of precision of the collection of patent documents by applying and inserting Quality Management contributions through the Define Measure Analyze Improve Control approach. The method adopted was the case study and the case unit the Nucleus of Technological Information in Materials of the Federal University of São Carlos. The development of the research comprised the stages of: a) definition of a conceptual-theoretical structure through literature mappings; b) planning the case; c) execution of the case, by mapping the processes, by developing an experimental method to increase the precision of the results of the collection, the survey, prioritization and proposals for improvements of the causes of low precision; d) elaboration of a new process incorporating the improvements. The results obtained were: a) model of intelligence process; b) subprocess model of collecting patent documents; c) proposals for corrective actions for improvements; d) choosing the best collection scenario; e) incorporation of the proposals into a new subprocess. It is concluded that the mapped processes are instruments that can be used by organizations and managers to more effectively manage the intelligence activity and collection of patent documents, being able to act as a driver for the implementation of activities, in the execution of training, in addition to allow greater knowledge and greater systemic vision of the activity and to solve incremental and radical problems and improvements. The new collection model can also be implemented to choose the patent databases to be used in Text Mining and Data Mining activities for Technical Intelligence.

The phenomenon of vagueness has been studied for centuries and is detected, among other characteristics, for creating the Sorites paradox. Vagueness is identified when we face the lack of precise limits of terms (or their use), as for example, ‘careca’ (‘bald’): where is the delimitation for someone to be, or not, characterized as bald? Could it be the delimitation the quantity of hair on one’s head that makes us say that one person is bald? If it is the quantity of hair that delimits this characteristic, what happens when one single hair stranded is added to one’s head; is the person not bald anymore?, or what if one single hair strand is removed from one’s head; has the person become bald? It seems that simply counting hair strands is not the solutions to our problem and doesn’t suit our purpose. Another matter debated regarding vagueness is about its origin, some authors believe that its nature is epsitemic: the objectis in the world that we refer to are vague; others say that its nature is linguistic: the terms used to refer to things are vague. Assuming the linguistic nature of vagueness as a problem on the terms or on use of the terms, Sauerland and Stateva (2011) elaborate a hypothesis to interpret this phenomenon, identifying two types of vagueness: (i) epistemic and (ii) scalar. As an argument in favor of this idea the authors propose the linguistic category of approximators: lexical items or construction that modify vague predicates making them more or less precise. Following this hypothesis, the approximators can be divided between two classes according to their compatibility with one of the two proposed types of vagueness. In this dissertation we aim to describe some approximators in Brazilian Portuguese (BP), and verify the duality of phenomenon in analysis, contributing to the description of (BP) and the comprehension of vagueness. In order to do so we delimit the vagueness phenomenon from the linguistic point of view separating it from other natural language phenomena; we then introduce a precise definition of vagueness and approximators and a method to investigate the linguistics mechanisms of the vague predicates, proposing a semantic and pragmatic description of some BP approximators.

This work copes with different processes of urban space production (“down” and “up”) and their relations to the land use, spatial planning, and to the social arrangement found in peripheral and poor areas – resulting of the integrated actions of the state, the capital, and other distinct social actors, such as public-private partnerships – which give sense to the local everyday life, specifically in the contemporaneous periphery of the city of Sao Carlos (state of Sao Paulo, Brazil). This thesis aimed to comprehend from the Federal Programa Minha Casa Minha Vida, Class 1(PMCMV-1), the urban space production and its processes of social arrangement in their varied scales, in the neighborhoods Jd. Zavaglia and Eduardo Abdelnur, through the state and its interrelations with other agents: real estate, non-profit sector, and residents. Also, processes of appropriation and reproduction of daily urban life by these residents, in the physical and symbolic dimensions, were considered. This study was carried through three main scales: federal, municipal, and local. In the federal scale, it was observed the juridical composition of the Program, the ways of production, and its target market. Specifically, the conceptual structure behind the indicators related to the habitational deficits and demands, and in which way they are related to the program productive chain and, consequently, to the urban space production and social arrangement, were analysed. The same structure with respect to the housing indicators was observed under the municipal scale. We wanted to understand why the municipality had produced an unexpected high number of residences though the PMCMV. Complementarily, we identified how the public and private agents acted towards the materialization of the studied neighborhoods. Lastly, in the local scale, ethnographic incursions were conducted in the two mentioned neighborhoods, through formal and informal interviews. Thereby, we made an analytical effort to think and understand the role of the PMCMV and its relations to the urban space, to the social arrangement, to private and non-profit sectors, and, finally, to the assisted population, addressing to comprehend: the current state plan under the neoliberalism and lulismo contexts, and the contours or limits of the public-private, legal-illegal, formal and informal relations. Some of the main research findings are: (i) the PMCMV presents a “super production by demand”, aiming to meet the real estate interests rather than the housing deficit; (ii) the public and private agents seems to work with harmony with the market needs at both national and municipal levels; (iii) the social policies tend to privatizing their financings and outsourcing their actions, leading to a private social management and a private urban space production through private institutions, such as general contractors and NGOs; (iv) the private management, sometimes called as mediation agent, is imbued with moralization, depoliticization of the state, and is accompanied with the introduction of business management practices; (v) the access to the social rights seems to be understood from a chance or individual merit point of view; and, finally (vi) a neoliberal ideology seems to be present in some levels of contemporary life, from social politics to the production of the neoliberal individual, presenting a continuous dynamic and porous infection between the spheres.

Carbon nanotubes presence in the environment increases every year as a result of exponential production around the world. In aquatic environments, carbon nanotubes can interact with other pollutants based on their nanoadsorbent characteristics. Heavy metals ions represent one of the biggest concerns in water resources nowadays, as a consequence of anthropogenic actions, in which cadmium (Cd) is one of the most harmful metal for aquatic organisms. This study investigates the effects of oxidized multiwalled carbon nanotubes (ox-MWCNT), of Cd ions and two interaction protocols in zebrafish liver cell line (ZFL): Incubation Protocol A, the ox-MWCNT were incubated in RPMI/L-15 (Roswell Park Memorial Institute and Leibovitz's-15) medium + 10% FBS for 30 min (step 1) and, subsequently, the CdCl2 were added and incubated for more 30 min (step 2); and (B) Incubation Protocol B, the ox-MWCNT were incubated with CdCl2 for 30 min (step 1) and, thereafter, the RPMI/L-15 medium + 10% FBS were added and incubated for more 30 min (step 2). Ox-MWCNT were physical and chemical characterized and its Cd adsorption capacity and colloidal stability in cell culture medium were determined. Cytotoxicity was investigated by four assays and the necrosis and apoptosis events and cell cycle were determined using flow cytometer. Cd content and uptake in cells was analyzed and ten biochemical biomarkers and the effects on DNA damage were evaluated. In this study, Cd presence in medium did not interfere in the protein corona composition of ox-MWCNT but the order of interaction of FBS and Cd can change its colloidal stability and metal adsorption rate. This study demonstrates that ox-MWCNT can increase the ZFL content of cadmium. The treatment with only oxidized ox-MWCNT promotes depletion of catalase, glutathione peroxidase, and glutathione S-transferase and led to alterations in cell cycle with a reduction of cells in G2/M phase. The ox-MWCNT affects Cd toxicity probably due to a “Trojan horse” and synergistic effects of both contaminants and induce apoptosis and necrosis in ZFL cells. We verify that the two co-exposure treatments performed increases the biological cadmium effect in ROS production and led to more genotoxicity damage in DNA. Thus, we show that an alteration in the order protocol method used for ox-MWCNT and Cd interaction in in vitro assays can modify the MWCNT-metal complexes formed and led to different biological effects. This study evidence the modulation of ox-MWCNT on Cd biological effects and contributes to future co-exposure investigations and legislation about with nanomaterials interactions with aquatic pollutants.

Rocky shore communities represent an important component of the biodiversity in coastal regions, but are subject to environmental impacts resulting from anthropogenic activities. Thus, understanding the mechanisms involved in regulating the populations of these organisms is necessary to predict responses to the various impacts to which these communities are subject. In the intertidal zone, mussels form bands that can harbor high diversity of associated organisms. Density increases in mussel populations, due to the intensity of intraspecific competition, can result in self-thinning processes (ST) that affect individual morphometry and, consequently, habitat availability for the associated fauna. This thesis consists of three chapters focused on incorporating the effects of the formation of individual layers in this cascade of effects (ST - individual morphometry - habitat availability). In the first chapter, we evaluated the relation of ST in two sympatric species of mussels with different environmental tolerances, using a tridimensional model with density measurements that incorporate the presence of layers. The tridimensional model better described the biometric responses to density increases in relation to the bidimensional models traditionally used to describe the ST relation, by incorporating the number of layers and a measurement of effective density. In the second chapter, the same measurements were used to evaluate the influence of density increase on the morphometric variation of the mussels. Again, density indicators derived from the tridimensional model were more effective in estimating intraspecific competition when there was overlap of individuals in the rocky shore. The layers can act as a mechanism of competitive relief and favor the growth of mussels. In the third chapter, we evaluated whether these new biometric indicators derived from the tridimensional ST model would be better descriptors of the structure of communities associated with mussel beds. We found that, even at a reduced scale (10 cm), the layers add physical structures that influence the distribution of the fauna and favor their abundance and richness. Therefore, the use of traditional density measures may result in the inability to detect effects of density-dependent processes in populations with spatial overlap of individuals. New models that better describe the packaging of individuals can contribute to a better understanding not only of population responses to increased density, but also provide a better description of the diversity of the associated fauna.

The degradation of lignin, which together with cellulose and hemicellulose constitutes the cell wall of plants, is generally hampered by its complex structure, its high molecular weight and its insolubility. However, fungi are able to degrade the lignocellulosic biomass by employing specific enzymes such as Laccases, Manganese peroxidases and Lignin peroxidases. This work aimed to identify and purify ligninolytic enzymes produced by four fungi: Mucor racemosus CBMAI 847, Penicillium oxalicum CBMAI 1996, Penicillium sp. FPZSP 151 and Chaetomium cupreum URM 5066. Through plaque activity using ABTS as substrate it was observed that C. cupreum and M. racemosus are the best producers of oxidases. The two fungi were then selected and cultivated in liquid medium, with the highest values of enzymatic activity observed on the 7th day of growth for both, and presenting 37.50±2.67 U L-1 for C. cupreum and 0.231±0.007 U L-1 for M. racemosus. It was possible to purify four enzymes present in the crude extract of M. racemosus, which have activity with veratryl alcohol, indicating that they may be lignins peroxidases. Three oxidases present in the crude extract of C. cupreum were purified and characterized, which have activity with substrates ABTS and SYR, at least one of the enzymes belonging to the subclass of laccases. Qualitative tests demonstrated that the enzymes produced by C. cupreum fungus were capable of degrading lignin. The results obtained in this work show that the fungi M. racemosus and C. cupreum are ligninolytic enzymes producers and that C. cupreum fungus has great potential for application in biotechnological processes, acting in the degradation of lignins. Moreover this is the first time that a purification of oxidases enzymes expressed by these fungi is reported.

The orchids of the genus Phalaenopsis are the most important in the segment of potted flowers in the national floriculture, being currently leader in volume of production and commercialization. However, obtaining genetic and phytosanitary quality seedlings at a competitive price has been one of the main obstacles for producers. Thus, the establishment of protocols of commercial applicability and that aim the production of clonal seedlings of hybrids is of great interest for the self-sufficiency of this sector. For this, micropropagation, through the production of somatic embryos (PLBs) or adventitious buds in somatic tissue segments in vitro, may be a viable alternative for the production of Phalaenopsis seedlings. This work aimed to establish efficient micropropagation protocols for Phalaenopsis hybrids using shoot induction techniques in inflorescence segments and induction and regeneration of somatic embryos (PLBs) in vitro from leaf segments of commercial hybrids. Based on the results, it was concluded that the use of the NDM culture medium plus 0.1 g L-1 inositol, 20 g L-1 sucrose, 0.1 mg L-1 NAA, 1.0 mg L-1 of BA, 1.5 mg L-1 of GA3, pH 5.7, is the most suitable for propagation of Phalaenopsis using inflorescence segments in the induction of shoots in vitro, being able to generate up to 1.7 shoots / segment and 71.5% of living segments. The contamination of the segments of inflorescence by yeast was the main difficulty found, reaching an average of 30% of contaminated segments. As for the induction of PLBs from leaf segments, the use of plant regulators BA and TDZ at a concentration of 1.5 mg L-1 each was beneficial for the regeneration of PLBs, whereas the different salt formulations used (MS and NDM) had little influence. The best results were 41% of regenerating segments and up to 5.3 PLBs / segment with the use of leaves with 20 days of subcultivation segmented in Thin Cell Layer. Under the culture conditions evaluated, it was not possible to obtain embryos using as explant segments of young leaves collected from plants under greenhouse conditions. According to the results, it was possible to prove the influence of the genotype factor on the induction and regeneration of PLBs.
