Bees are the most important pollinators of agricultural ecosystems by carrying out pollination of up to 90% of native plants and more than one third of cultivated plants. Studies conducted around the world have been demonstrating a phenomenon called CCD (Colony Collapse Disorder), whose causal agent several factors including diseases that affect this group. Among them, the varroa resulting from the Varroa destructor mite attack, is reported as pathogen major impact factor on the Apis mellifera. In view of this, the objective of this study was to test the efficiency of three methods to control V. destructor: alternative, obtained from the distillation of oregano (Origanum vulgare Linnaeus, 1753), thyme (Thymus vulgaris Linnaeus, 1753) and sugar beet (Beta vulgaris Linnaeus, 1753); biological, run base drones and larvae chemical, carried out with the application of active flumethrin principle. The results were evaluated by statistical analysis in R program to determine the differences between treatments and proposed mergers and select the best method of control. In the analysis, it was observed that the alternative method showed a significant difference by highlighting thyme distillation as more efficient because there is no significant killing of bees and cause the death of all the mites in a shorter time compared to the other distillates. The biological method hornets larvae base is also preferably effective due to mite in these individuals. In chemical control the use of the active ingredient flumethrin caused poisoning in bees, with diarrhea in the first 6 hours after application, and after 48 hours caused a mortality of 100%, which demonstrates be impractical to control the mite.

Known as the Age of Conversation, the present time is marked by horizontal communication, based on connectivity between people and their networking. This setting reconfigures the media landscape from new conversation environments such as podcast. The present dissertationinvestigates the contents of Podcasteros produced by a network of Brazilian fans of the television series Game of Thrones (HBO, United States, 2011-present). The understanding of the series, the strategies used by HBO and content produced by fans aims to discuss a business model based on participatory culture that prioritizes dialogue not always friendly between producers and fans. At first, the series will be presented whose complex narrative universe unfolds through multiple plots, characters and settings - which leads the viewer to search for information on other platforms to understand not only what is narrated as sharing, networking, their impressions and versions of history. Observe the discursive network of fans around the series, therefore, requires the understanding that it is formed from ephemeral and temporary ties and marked by discursive diversity of its members. Finally, the Podcasteros content analysis will be addressed. The methodology proposed merges content analysis and netnography and is an investigative journey that seeks to meet the specific characteristics of the object and its sound nature in the context of discursive networks of fans and their dialogic practices.

This work attempts to the encounter between humans, dogs and streets. The focus is to explore the power of the relationships established among these entities, in the public space, when they meet each other and their homes through art. The goal is to affirm the existence and permanence of dogs on the streets and evoke the production of new feelings and sensitive connections between humans and them. The exhaustion of the thought about some prevailing notions on the distinctions among entities, and also the opening to the sensations and affections evoked when dogs and humans meet each other, on the streets, through art and words, serve to the questioning of the relationships between them and their homes, and also to a resizing effort on those relations, enabling the vision of the stray dogs status as beyond the categories of abandonment and suffering. The methodology is the cartography, as proposed by Gilles Deleuze e Félix Guattari, which takes in the experimentation of the thinking, trying to realize the dynamics, fluxes and intensities of the objects and assuming that the thinking and the knowledge production starts always from multiple connections. In the field of the theory, we performed a bibliographic research on contemporary authors of anthropology, philosophy, psychoanalysis and the arts as a way to resume and shuffle some concepts and also make other means and viewpoints possible for the relationships among entities. In the field of the praxis, the fieldwork involved some walking with the stray dogs in the city of Sorocaba. We also produced some narratives taking the fieldwork as inspirations, and some wheat-paste urban interventions, both as a way to create powerful encounters between humans and dogs on the streets where they come across to each other.

Aspergillus fumigatus is an opportunistic pathogenic filamentous fungus, and the causative agent of aspergillosis, including the invasive pulmonary aspergillosis in immunocompromised individuals, most lethal form of the disease. As in all eukaryotes, the plasma membrane of A. fumigatus is composed of sterols, glycolipids and sphingolipids. The sphingolipids molecules are structural elements that participate in the regulation of the actin cytoskeleton endocytosis, and cell growth. In Saccharomyces cerevisiae, the sphingolipid synthesis is regulated by proteins such as the "AGC kinases" known as Ypk1p and Ypk2p that inactivate Orm1p and Orm2p, which are inhibitory proteins of the serine palmitoyltransferase (SPT) enzyme, the first enzyme that participates in biosynthetic pathway of sphingolipids. Thus, Ypk1/2p are responsible for stimulating the production of sphingolipids in response to several cellular stress factors, such as cell wall stress and heat stress. Here, we aimed to expand the study of sphingolipid biosynthesis in A. fumigatus by functional characterization of the ypkAYPK1 gene by establishing its role in the regulation of sphingolipid synthesis and in the maintenance of cell integrity. To accomplish this goal, one null mutant strain ΔypkAypk1 and a conditional mutant strain niiA::ypkA of A. fumigatus were obtained. The mutant strains were characterized by phenotypic tests aimed at understanding the role of this gene in sphingolipid synthesis, virulence and pathogenicity of this fungus. Subsequently real time RT-PCR experiments were performed to quantify the expression of this gene in conditions of heat stress. The results indicated that deletion of the gene ypkA promotes changes in the development of the fungus, which presents severe defects in the vegetative growth and absence of conidia. In addition, the conditional mutant shows increased sensitivity to lipid synthesis inhibitory drugs. The results also indicate that there is no interaction between genetic ypkA and pathway genes of the cell wall. Thus, we propose that protein kinase YpkA in A. fumigatus is related to vegetative growth and participates in the sphingolipid biosynthesis in A. fumigatus, contributing to the development and integrity of the fungal cell.

In Brazil, there are few studies on mountain ecosystems that aims the biodiversity conservation, even with hymenoptera parasitoids, especially the family Braconidae, a group ecologically important, because they represent the diversity of other groups of insects, that are their hosts. This study aimed to contribute to the knowledge of the diversity of Braconidae fauna into a mountain ecosystem at Parque Nacional do Itatiaia, Rio de Janeiro, Brazil. The sampling were made with Malaise traps (TOWNES, 1972) installed between 987 and 2255 meters, in two mountain slopes (continental and coastal), comprising three vegetation types of the Atlantic Forest existent in the study area (Montane and High Montane Ombrophilous Dense Forest and Campos de Altitude). Four altitudes were sampled for 10 months of sampling between 2011 and 2012 and seven altitudes in 14 months were sampled between 2013 and 2014. In total 9.854 individuals of Braconidae were captured, in which, 8.814 individuals were identified and distributed in 28 subfamilies and 125 genera. The most abundant subfamilies were Alysiinae Microgastrinae, Doryctinae, Braconinae e Opiinae. The most abundant genera were Opius, Heterospilus, e Bracon. The rainy season promoted the major richness and abundance of subfamilies and genera. Two patterns of the richness and abundance distribution were observed: in the gradient sampled in 2011-2012, the richness and abundance increased with altitude showing peak in the highest altitude; in the gradient sampled in 2013-2014 was observed a peak on intermediate altitude, followed by decline with elevation. The richness accumulation curves have not reached the asymptotic stage. However, the richness estimators showed that the sampling period was sufficient to know most of the local fauna. Most of the abundant genera showed high amplitude of altitudinal distribution. It was observed a great number of exclusive genera. Some of the main subfamilies showed preference for higher altitudes. Most of the identified fauna are cenobiont, endoparasitoid solitary of larval stage of Lepidoptera, with small range of hosts. Many identified genera have biological information missing. Apparently the parasitoids community structure was strongly influenced by the vegetation gradient on mountain. The High montane vegetation showed a richer fauna, and the Campos de altitude, showed a more dominant fauna. In the gradient sampled in 2011-2012, cenobionts and idiobionts showed peaks in the highest altitudes, in the gradient sampled in 2013-2014, cenobionts and idiobionts showed a peak in distinct altitudes. In the spatial and temporal distribution of cenobionts and idiobionts, it was observed a typical pattern of competition. In the highest altitudes, ectoparasitoids were more frequent than endoparasitoids. Most of the genera without species recorded for Neotropical Region and Brazil, were more frequent in the highest altitudes. Two genera new for science were recognized, and at least 46 new species were discovered. Studies such as this show the importance of research in altitude ecosystems, allowing the biodiversity and the ecological importance of these habitats to be known.

Since the colonization of Brazil, its indigenous peoples have been facing countless conflicts related to the protection of their territories. In the pursuit of better living conditions, several indigenous communities have been thinking of tourism as a local development alternative based on criteria established by their own ethnic groups. The aim of this research was to identify the possible impacts and consequences for ethnodevelopment which were caused by the ethnic tourism developed and applied to Tabaçú Reko Ypy village, which is located between the municipalities of Itanhaém-Peruíbe on the southern coast of São Paulo, from 2013 to 2015. The community develops and performs this activity as a supporting tool for generating alternative income with the purpose of improving their living conditions and recovering their territory and traditions. Due to the fact that it is a recently formed village, no specific literature about its people has been found. All the documents and information about their politics, social behavior and culture have been obtained through semi-structured interviews, participation in field experiences and documents provided by the indigenous people themselves. The theoretical framework for this research was obtained through the existing literature on anthropology and tourism and its interfaces. This community organizes some field experiences related to tourism in partnership with agencies and also autonomously which were monitored and registered for this research for two consecutive years. Through this study, it was possible to identify several consequences arising from ethnic tourism and to reflect on possible future impacts that can be dealt with. In conclusion, this research showed that, through the actions taken by the Ñandeva people over the two-year period from 2013 to 2015, the possibility of making use of new tools and guidelines will be useful for them to achieve autonomous ethnodevelopment with the perspective of an inclusive model of tourism capable of generating income, respecting local culture and promoting environmental balance.

In the past few decades, following the growing trend to create partnerships between public and private sectors in multiple countries, this topic has been broadly discussed in global academic production. The main purpose of this research is to identify potential relationships in those partnerships’ structure, how they are handled, and the results they aim to achieve. For that matter, this paper presents an overview of the subject, taking into account the context of emergence and development of those partnerships in Brazil and in the world, the different terminologies and concepts used to discuss them, and the multiple possibilities to characterize them. Three aspects were considered for the characterization, namely: 1) the partnerships’ hardware, composed by their standards, constitution and objectives – its physical structure; 2) the partnerships’ software, or how their members relate to one another, to other actors, to their organizations, to society, and to the public and private systems that surround them – its governance; and 3) the results aimed by partnerships. The government program Água Para Todos (APT), one of the measures for the governmental plan Brasil sem Miséria (BSM) – a strategy by the Federal Government (2011-2014), which aims to overcome extreme poverty in Brazil – was selected to approach this theme and to illustrate the rationale behind partnerships between public and private sectors. In the form of different arrangements to achieve the objective of making the access to water universal in the Brazilian semi-arid region, the participation of actors from public and private sectors joining efforts and taking turns on different roles was critical to assure that the goals established by the Federal Government were fulfilled and to foster other benefits for the population as well. It was also possible to observe that the three aspects of partnerships considered for the analysis affect one another. Just as the partnership’s hardware affects its governance, any kind of obstacle faced by the form of operation might result in changes to the previously constituted structural elements. The possibility to reassess the continuous forms of partnerships’ hardware and software might be one of the requirements to achieve the best possible results. At the same time, tracking results along the partnership execution might point to difficulties and bottlenecks which, occasionally, would act as guides to the required changes to its structure and governance.

Manifestations Work-Related Musculoskeletal Disorders (WRMSDs) in the workplace have been of concern, as its growth has forced the society to deal with this problem high economic impact due to the significant increase in the number of absences related to work. After diagnosis and removal, the INSS medical expert, according to conditions / worker capabilities, forwards it to the Vocational Rehabilitation Program INSS, which should provide the means of professional and social rehabilitation, according to the Federal Constitution. However, the difficulties of the Ministry of Social Security in return method of workers away by WRMSDs has been the subject of discussion. This study aimed to understand of the process of return to the employee's work away for WRMSDs, through the activity of ergonomics, focusing on the need for interaction between business, labor and INSS. The methodology was designed / led by a return to work flow chart created by the researcher from the model of inclusion of people with disabilities of Simonelli (2009). The methodology consisted initially of approval of UFSCar's Ethics Committee for the collection and analysis of data in the four companies that agreed to participate, and Term of Consent of workers. For data collection, the workers were interviewed, underwent evaluation capacity for work, from protocols and core set of ICF and were followed in jobs for systematic observation and understanding of the activity, as a presupposition of ergonomics activity. In the study of different cases it was found that the activities analyzed show that the removal station for reintegration post significant changes. Some study companies have a program for approaching the worker in the period of clearance. The professional courses offered by the INSS, mostly do not meet the requirements of the tasks of the companies, therefore, do not help the worker in the process of returning to work. The worker who returns clearance, is generally placed in the position that the company chooses, since it seeks to meet the restrictions that the Vocational Rehabilitation Program prescribes. However, this does not help you during the process of reintegration and skilled professionals of the company did not accompany him regularly. With the observed situations, it is concluded that the actual return depends on the joint work of these three social actors (company, employee and Vocational Rehabilitation), which complement each other, including analysis of activity in the stations selection process for inclusion, aiming discussions generate fruits that benefit workers and, consequently, companies and the INSS.

Alternaria Brown Spot (ABS), caused by Alernaria alternata a fungus which produces a host specific toxin (HST), is a disease of huge importance in mandarin orchards in many producing regions in the world. The selection of varieties resistant to disease is of great economic importance. In this study different hybrids of citrus were evaluated. These hybrids were obtained by directed crosses and preselected by agronomic characteristics that make them potential new varieties of oranges and mandarins, for industry or fresh fruit. The evaluation of these new genotypes is an essential step for the release of new varieties. Seventy-nine hybrids and their parents were subjected to inoculation with an isolated from A. alternaria in detached leaves and plant assays. The severity of disease was measured by the scale described in the literature. The evaluation of Mendelian segregation in hybrids of Murcott tangor and Pera sweet orange, evaluated in greater numbers, allows inference about the genetics of resistance heritability of ABS and to map the genomic region associated with the fungus using an integrated genetic map previously obtained. Different responses were observed after the fungus inoculation. Five hybrids of Willowleaf mandarin like, six hybrids of mandarin like, three hybrids of Murcott like and 21 hybrids of orange like, resistant to ABS, or with few symptoms of the disease were selected. High values of heritability and genetic variability measured indicate that the selection of resistant plants in the progeny can be successful. A resistance gene and molecular markers associated with it were located in the same linkage group 3 of integrated map of Murcott and Pera. The selected genotypes constitute potential material for commercial planting and for the control of disease in the field.

The silviculture activity, as well as other economic activities (industrial, agrarian, farming, etc.), can cause environmental impacts, both positive and negative, according to a number of circumstances, such as in relation to the conditions prior to planting, water regime in the region, the biome of insertion of the activity, the management techniques employed, the integration of the local population, among others. Plantations of exotic species (ex. genera Eucalyptus and Pinus) have been the subject of severe criticism regarding the possible reduction of biodiversity. These criticisms have arisen from situations and relationships that conflict that have occurred, for decades, between those responsible for the implementation and use of these plantations on one side and the other people aware of the need for preservation of biodiversity. In this study we selected 15 Brazilian companies that are certified to the Forest Stewardship Council (FSC) with the aim of assessing whether the Management Plans from forests certified by the Forest Stewardship Council (FSC) had evidence of the use of the results of monitoring of biodiversity (especially fauna) in interventions of forest management aimed at biological conservation. The method used was the documentary analysis of the Public Summaries of the Management Plans, between the years of 2011 to 2015, available on the internet. Among the several results obtained, of note is the fact that the 15 forestry companies, 13 (87%) conducted an inventory of qualitative and quantitative aspects of wild fauna, and analyzing the total hectares of areas monitored in relation to the total number of areas in plantation of eucalyptus, in 8 (53%) forestry companies monitoring is conducted in areas that have a range of 5% to 47% of the areas under certification. We can observe, through critical analysis of their management plans, in which they are sampling of static form the structure of biodiversity, through lists of species. It concludes that there are no concrete evidence of the use of information obtained through monitoring of fauna for making decisions about the best ways of intervention of forest management, indicating uncertainty when the real possibility of same to assist in the conservation of biodiversity. This way, was proposed a protocol model for monitoring of fauna, with specific methodologies for the group of wild mammals. In this case, the results can be used in the assessment of the impacts of forest management of forestry companies contributing to the fitting of the form of forest management compatible with the maintenance of its biodiversity.

The bat community of the Jatai Ecologic Station region, Northeast of São Paulo State, was studied by comparing bat species surveys, in three forest fragments, to investigate the two components of species diversity, richness and abundance. Twentytwo bat species were recorded, with the sum of the species from the three fragments. Three phyllostomid species were dominant in two forest fragments, and two Molossidae species were dominant in other. Many bat species were rare. Species diversity obtained, measured by the Shannon index (He '), was similar in the three fragments, and close to the values of most studies of brazilian Southeastern bat communities (He’close to 2.0). This suggests constancy in the pattern of species diversity of bats in this region, and also in Southeastern Brazil. Of the 22 species recorded, four can be considered highly sensitive to the habitat fragmentation. The diversity achieved was significant, highlighting the value of these protected areas for the maintenance of local and regional biodiversity. The Red List of IUCN (The IUCN Red List) has been used to provide information about the conservation status of the species worldwide, and the same subsidize jobs assigned to this issue, with special focus on endangered species. At the national level, ICMBio (Chico Mendes Institute for Biodiversity Conservation) has the same goal, to discuss the conservation status of the Brazilian species, developing lists that guide actions to protect them. Using the information provided by IUCN and ICMBio, and bats records in the cerrado, considering the Brazilian territory, here are discussed aspects of ecology and conservation of bat species, in order to clarify some aspects of interest in this topic. Using the spatial interpolation method (IDW) to estimate the possible value of species richness in places not sampled species, was evaluated knowledge about the species richness of occurrence of bats in the cerrado of Brazil.

Reinforced concrete structures built in coastal areas, such as electricity distribution poles, are constantly attacked by aggressive environmental agents. Rebar corrosion mechanism is a specific manifestation of electrochemical corrosion in an aqueous medium, thus the mechanism of corrosion of steel in concrete develops only in the presence of water or environment with high relative humidity (R.H.>60%). Chloride is known as one of the most aggressive environmental agents, causing rebar corrosion and consequent degradation of the concrete. Chlorides can reach the steel reinforcement through the pores network present in the concrete, if the device is close to marine atmosphere. The chloride content increases with time, and can attack the entire surface of the rebar, and may result in severe and dangerous corrosion velocity. Corrosion results in a decrease in rebar section and cracking of the concrete in parallel direction. The cracks occur because of corrosion products occupy more space than the original steel. In São Luis, concrete poles located on the coastal area has presented different types of pathology, mostly linked to performance of the chlorine ions. As a consequence, the life of these parts has reduced dramatically, generating maintenance costs. Therefore, this study intended to develop alternatives aimed at increasing the durability of reinforced concrete poles, by reducing the transfer of chlorides in their concrete cover, through variations in trace and concrete chemical composition, evaluating the influence of these parameters on its mechanical resistance. Therefore, many specimens were shaped with different compositions, using Type CPII E-32 Portland cement (compound slag) with water / cement ratio ranging between 0.4 and 0.5. Concrete mixtures containing silica fume (in order to reduce the capillary) and red mud additions (in order to protect the equipment by reducing the free chloride content) were also tested. Durability assessment of concrete was based on the results of its physical and mechanical characterization, on the electrical resistivity evaluation of concrete and rebar corrosion potential. Results show that silica fume and red mud addition reduces porosity and water absorption of concrete samples, as well increases mechanical strength, when compared to currently used concrete for poles manufacturing in São Luis. Additionally, it revealed a drastic reduction in rebar corrosivity when covered by concrete with these additions, tripling the life time of poles.

This study aimed present the máster’s dissertation named Canjerê: uma performance cartográfica em patrimônio cultural, educação e africanidades, held in the Postgraduate Program in Education of the Federal University of São Carlos (UFSCar). This research is proposed to follow the process of an experience lived by individuals and black cultural practices, which resulted in creation of Instituto Baobá de Cultura e Arte – o Ibaô – in Campinas (SP). The movement of this research reveals an experience as possible against what is hegemonic tax as only true culture, from the practice of Capoeira and other black cultural expressivity. Based on the invisibility of issue of black people, this process offers clues to the construction of aternatives that break the dominant models, weaving reflections on the social hostilities that affect the uniqueness and identity construction centered africanities and as the prospect of knowledge of ecology can contribute to the construction of new existential territories.

This thesis explored aspects that can help balance the level of user control and system autonomy for intelligent privacy agents in the context of the Internet of Things. This proposed balance could be reached considering aspects related to wanting to be interrupted to have control and being able to be interrupted to exert this control. Through literature review of interruption and privacy literature, variables related to these two perspectives were identified. This led to the variable set "Intelligent Privacy Interruptions”. To verify and validate this set, two research actions were performed. The first one was an online survey that allowed us to perform a sanity check that these variables were acceptable in this work’s context. The second was an experience sampling user study with 21 participants that allowed us to better understand how user behavior is informed by these variables. Based on these two interventions it was possible to note that the selected variables seem to show relevance and that they can be used to inform the development and design of privacy agents. The limitations of the partial results notwithstanding, through a quantitative analysis of data collected form the user study and the qualitative analysis of the exit interviews, it was possible to note a common mental process between the participants of the user study when deciding whether to withhold or delegate decision control to the agent. Future studies should be performed to verify the possibility of expansion and creation of a behavior and preference model that can be integrated to the decisionmaking system of intelligent privacy agents.

This work falls within the scope of the investigation of the initial teacher training, investigating the Institutional Scholarship Program Introduction to Teaching. This is a case study in which it is carried out an analysis of PIBID-Biology subproject of the Federal University of São Carlos (UFSCar), which is part of PIBID UFSCar-institutional project. From an analysis of all documents relating to the implementation of the project at all levels (national, institutional and subproject) as well as the interview with researchers involved in the construction of these projects, we built a description of the processes involving the construction of the national project, as well as the institutional design and, finally, the subproject Biology UFSCar. This first step was the context for understanding, through analysis of reflective portfolios produced by scholars, the dimensions of teaching knowledge built by undergraduates as scholarship students from PIBID. In light of the training teacher references (NÓVOA, 2009; ANDRÉ, 2012, GATTI, BARRETTO & ANDRÉ 2011, Zeichner, 2010, among others), knowledge of the teachers (PEPPER, 2005 Tardif, 2000, 2007) and also Complexity Theory (BONIL & PUJOL, 2008; RIBERAYGUA, 2012; MORIN, 2004, 2005), we realized that, despite the PIBID have characteristics that approach a complex and dynamic model, students have many difficulties in view their performance as part of a complex system that involves not only the classroom but the entire surroundings. We understand that this may occur because not always the PIBID works in coordination with the context , undermining thus functioning as a dynamic and complex system , requiring several adjustments and improvements in this program.

Sugarcane is a renewable source of energy and has potential for expansion. The economic importance of sugarcane is due to its use as raw material, mainly for the sugar and ethanol production and, more recently for the electricity generation from lignocellulosic residues. The genetic improvement of sugarcane is responsible for releasing more productive and resistant cultivars but, however, is a long process with high cost. Furthermore, the sugarcane is polyploid and often presents aneuploid, which makes the work of breeding programs even more hampered. Thus, the phenotypic and molecular knowledge of the access that are commonly used for the crosses to obtain segregating populations or that are part of genebanks of breeding programs is of extreme importance, because this knowledge may drive the improvement process and increases the chances of selecting superior cultivars that meet the demand of the sugarcane industry. In this work, a panel of 242 genotypes of sugarcane, which compose the Brazilian Panel of Sugarcane Genotypes (PBGCA), was planted in the Agricultural Sciences Center of the Federal University of São Carlos, at Araras-SP, in a completely randomized block design with four replications. We evakuated eight phenotypic traits of economic importance: stalk height (m), stalk diameter (mm), stalk number, total weight (kg), soluble solids content (ºBrix), juice sucrose content (POL%Caldo), cane sucrose content (POL%Cana) and fiber content (FIB%); and also the incidence of brown rust (Puccínia melanocephala) at field and the presence of the resistance gene of this disease (Bru1). The estimate of variance, genotypic correlation analysis and principal component analysis showed the genetic diversity of PBGCA, which has, for example, contrasting genotypes for sucrose content and fiber content. In addition, from all resistant accessions on the field to brown rust, 72.30% present the Bru1 gene, which is strongly associated with resistance. Phenotypic and molecular characterization of PBGCA showed to be an efficiently important guide for the breeding strategies and enables future studies of association between traits of economic importance and molecular markers in order to perform assisted selection in sugarcane.

This research has the general objective to analyze the perceptions that school directors from kindergarten in the city of Araraquara / SP have on their own work in order to identify if they understand their eminently pedagogical nature. For this, a qualitative research was done, interpretative type, using questionnaires and semi-structured interview. The data analysis used the triangulation technique, building a profile and an analysis of their perceptions of the pedagogical and administrative activities. For this analysis, the study is based on the concepts of school administration (PARO 2011, 2015); and formation in school management, autonomy and decentralization of education (LÜCK, 2000). It supports also the idea of the need to build a theory for the administration of public school and valorization of the Pedagogic Political Project (SILVA JR, 2015;. VEIGA, 2009). This study deals with, briefly, the subject of education in postmodernity (Hargreaves, 1998), seeking to establish a relationship of social change - democratization of education and the new clientele; crisis of utopias and knowledge; dynamism and access to information - and its new demand for school, changing roles of agents that act on it. This process resulted analytical axes: "Options for career"; "Insertion in school management"; "School director formations" and "Activities undertaken by the director." Data composed the profile of an overloaded professional, devalued, responsible and hamstrung. In relation to its activities directors emphasize pedagogical is not a priority since the purpose of exclusively bureaucratic overlaps them. In the case of directors of early childhood education in Araraquara, this scenario is intensified due to the lack of a team of administrative and pedagogical support. In this respect, there is a devaluation of this level as the other directors of the network, the other levels and programs, which entered the same process with the same requirements, have these agents. Consequently, perceives the hegemonic thought that the school of early childhood education is a guard location and care of children without educational nature. As for the numerous formations made by the directors, none was cited as something significant in aid of their activities, so this research brought contributions to the initial and continuing education, demonstrating the need for dialogue with the everyday working practices of directors, avoiding also a clash with the real beginner’s directors. As for the results, for the Municipal Araraquara and its supervisory staff, the data show the number of documents requested, sometimes with the same data and the difficulty of the director alone, turn to the pedagogical work, and noted the need reframing of this position, due to the working conditions and depreciation already mentioned. The data also showed that this research brought moments of reflection for directors on the roles they play, including raising the request of some of them to create a study group. Finally, for the researcher and supervisor, which in this movement to stop to listen to these managers, its operations and spurred to seek new knowledge and ways of doing things that enable the pedagogical action of directors in schools.

The identification Selenastraceae family organism is performed by optical microscopy only on diacritic characteristics, what has been questioned from recent molecular studies. Conflicts between phylogenetic, morphologic and genetic results were found after analysis of a large number of species Selenastraceae, and misidentification and consequently error in the classification directly leads to that the underestimation of species from Selenastraceae family. An alternative to these errors in identification and classification would be avoided using a polyphasic taxonomic approach to this family, combining to morphology, genetics, physiology and chemotaxonomy. Therefore, the use of fatty acids found in microalgae as an alternative to contribute assist in identification can be feasible. Using this information, this study considered the fatty acids of sixteen strains of microalgae from Selenastraceae family and found specific fatty acids and may differentiate between strains of microalgae and has presented fatty acids indicators from the Selenastraceae families (C18:3ω3 and C18:4ω6), Scenedesmaceae (C18:2ω6, C18:1ω9, C16:2ω6) and Oocystaceae (C18:3ω6) and also genera Monoraphidium (C16:1ω9 and C16:3ω6), Coelastrum (C18:1ω9) and Nephrocytium (C18:3ω6). Among Selenastraceae was detected potential with fatty acids for the production of biofuels (C18:1ω9), to feeding to animals (C16:0) and polyunsaturated for human nutritional supplements (C18:3ω3, C18:2ω6 and C16:4ω3) according the growing stage of these organisms.
