This research aims to understand the process of initiation into teaching of graduates of Institutional Scholarships Program initiation into Teaching (PIBID) at the Federal University of São Carlos, in the area of Mathematics. In order to identify the contributions and limitations of this formative process, under the gaze of the scholars graduating from the same, we seek to answer the following question: what are the main guiding perceptions of the graduates of the PIBID/UFSCar of Mathematics in its process of initiation to teaching, about difficulties and learning of teaching career? We left a few theoretical assumptions of the learnings teachers (MIZUKAMI ET. AL., 2003; TANCREDI, 2009, GUARNIERI, 1996, 2005), and in particular, the initial stage of career (HUBERMAN, 1995; VEENMAN, 1988; CAVACO, 1995; MARCELO GARCIA, 1999; TARDIF, 2012), which has its own characteristics and is usually marked by feelings of "survival" and "discovery" that may influence the permanence or not on teaching career. For recognition of the scenario, identifying the dynamics and particularities of the programme at the national level and institutional, were used documents, projects and publications. For data collection we chose three steps. First perform the mapping of the scholars who participated in the program, in which count 35 scholars in 3 years of subproject and routing of a questionnaire. The initial questionnaire included data about initial training, training in the PIBID and professional experiences, including teaching jobs or not, in order to draw the profile of the scholars and alumni. This step also seek to identify the graduates who followed the teaching career for the deepening of the data thus followed five subjects for the second step. This was created by the analysis of the reflective writings of graduates still at the beginning of their careers, in order to identify and: the main activities developed in the PIBID. In the third and final step, we conducted interviews with four subjects employees (Amanda, Beatriz, Olavo and Viviane), teachers graduates, in order to understand perceptions about the process of training, entry into the profession and future prospects. We look to analyze data from graduates of the PIBID/UFSCar/Mathematics through their difficulties and learnings narrated, composing two axes of analysis: (1) Characteristic Aspects of early career and (2) Dichotomies and joints of training and professional practice. The characteristics and feelings of teachers beginners pointed by literature are revealed in all the subjects ' initiation process, starting in experiences in the following program in the early years of teaching, but with few indications that some difficulties are overcome by the learnings generated at the time of formation, which contributes to the professional insertion. The program also seeks to provide the articulation between theory and practice to licenciandos, seeking to overcome the dichotomies between School Mathematics and mathematics academic training that reflects directly in professional practice. Also highlight the continuing training, realize their trajectories, their gaps, difficulties arising from inexperience. However, are reflective and interested in becoming increasingly better teachers and to develop professionally in career.

(Universidade Federal de São Carlos, 2014-05-29) Macedo, Vanessa Marcele; Kupper, Katia Cristina; https://lattes.cnpq.br/7900622063392740; https://lattes.cnpq.br/2809177515064081
The species of fungi belonging to the genus Trichoderma can be found in many environments, especially in the rhizosphere, as colonizers of roots and plant growth promoters, for their ability in facilitating the absorption of nutrients and protecting them against attack by pathogens. Thus, this study aimed to test isolates of Trichoderma spp. for application as growth promoting agents and inducers of resistance to Phytophthora nicotianae in citrus rootstocks. First, eighteen isolates of Trichoderma were tested in vitro for their ability in inhibiting mycelial growth of P. nicotianae, in terms of: production of volatiles or termostable antifungical substances and cell free compounds. The growth promotion test was done with three rootstocks: Sunki tangerine, Swingle citrumelo and Rangpur lime, whose height and number of leaves were measured at 30, 60, 90, 120, 150 and 180 days after treatment with the antagonistic; and in the end of the test, the measuring of dry weight for shoots and roots of plants was measured. The seeds of the rootstocks were treated with the Trichoderma spp isolates and, 180 days later, was tested their capacity of resistance induction through pathogen inoculation on stem, assessed by lesion length. The Phytophthora control assay was carried out by seeds microbiolization of tangerine Sunki and Rangpur lime. By the results, it was found that all Trichoderma spp. isolates provided more than 50% inhibition of the pathogen colony, however, no one produced volatile metabolites. Five isolates produced cell free metabolites and, only the ACB-38 produced termostable antifungal substances, capable of inhibiting the pathogen growth. Trichoderma spp. has the potential for rootstocks growth promoting and resistence inducing to P. nicotianae, but the responses vary according to the plant genotype and the type of isolate antagonist applied. Most isolates of Trichoderma spp. tested were able to control P. nicotianae in Sunki tangerine and Rangpur lime plants.

(Universidade Federal de São Carlos, 2014-05-29) Santos, Tiago Pomponet Carmo dos; Teixeira, Cesar Augusto Camillo; https://lattes.cnpq.br/1123376648713853; https://lattes.cnpq.br/4243557646613152
Since its creation television has undergone major paradigm shifts, from black and white images to color displays, from analog systems to digital transmissions, from low quality display to high quality displays, from passive programs for fully interactive programs. Currently the term Social TV is gaining popularity in television and innovating once again the way people watch TV, combining computing and communication mechanisms to provide new ways to entertain and inform the viewer. The object of this work lies in the context of Social TV, explores the concept of support agents that have the role to stimulate social interactions, having the aim of enrich the quality of experience in watching television. This paper proposes a model of interaction between the agent and the viewers in Social TV systems and tests with users using a tool developed for the interaction model. Finally the paper compares the results of interactions to investigate the influence generated by inserting the support agent in an environment of Social TV.
Efeito anti-inflamatório do extrato etanólico da Harpagophytum procumbens durante a inflamação intestinal de camundongos infectados com Salmonella Enteritidis (ATCC13076)
(Universidade Federal de São Carlos, 2014-05-29) Bisinotto, Rosalia do Carmo; Anibal, Fernanda de Freitas; https://lattes.cnpq.br/4918261968772806; https://lattes.cnpq.br/9254279796721990
Salmonellosis is an illness caused by bacteria of the genus Salmonella, a leading infectious disease worldwide. Due to the importance of this infection forward to eating habits, the search for a new compound that can contribute to current therapy against intestinal inflammation caused by Salmonellosis is of great value. The goal of this research was evaluate of this treatment effect with extract of Harpagophytum procumbens ( Hp ) in murine intestinal salmonellosis . In this research were realized counting of total cells and differential cell ( leukocytes, neutrophils and mononuclear cells) , dosages of cytokines (TNF- α , IL-12 , IL-10 and IL-4 ) and histopathological analysis of the liver and small intestine, at third and seventh day after the infection on animals treated with Hp and with animals didn t treated with. The animals were divided in: infected ( SE ) , infected and treated with Hp ( SE + HP ) and control group( C ). Balb / c mice ( female) were infected ( v.o ) with S. Enteritidis ATCC 13076 ( 1x108 UFC - 100 mL / animal) . The SE + HP group was treated with 150 mg / animal daily with Hp . The pathology of the liver and small intestine was prepared and stained with HE. Our results showed that there was an increase of leukocytes, specifically mononuclear cells analyzed in different compartments ( blood and CSF ), increased neutrophils in the blood in animals infected with SE on day 7 after infection. However, treatment with Hp was able to down modulate the recruitment of mononuclear cells on day 7 into the peritoneal cavity and negatively modulates the number of neutrophils in the same period. The levels of TNF-α showed a decrease on day 7 after treatment with Hp, suggesting a biological effect - down regulation - the inflammatory process in these animals . Furthermore, we also observed that animals treated with Hp infected with SE had a reduction in the number of neutrophils and mononuclear cells in the blood and decrease of IL -12. The production of IL-4 showed an increase in the + SE group HP suggesting that animals infected with S. Enteretidis and treated with H. procumbens appears to favor a microenvironment that directs the immune response profile of Th2 to Th1, whereas IL- 12 showed a decrease. IL- 10 has important regulatory effects on immunological and inflammatory responses mediated predominantly by macrophages. Our results show an increase of IL-10 in animals infected with SE, and this increase seems to be related to the severity of salmonellosis. Treatment with Hp stimulated inhibitory activity of IL - 10, favoring slight inhibition of the inflammatory process, on day 7 after infection. In the histopathological analysis of the liver observed that there was no difference between the groups, suggesting a local infection, since the blood culture was negative, carrying no systemic infection. In the small intestine was observed after 72 h in the SE group discrete wrinkle this epithelium, suggesting the invasion of S. Enteritidis, which was also observed hypertrophy of the wall of the villi and mild inflammatory infiltrate. In animals that received treatment with Hp hypertrophy was reduced with preservation of the villi of the intestinal architecture 7 days after infection. Thus, we suggest a possible role of Hp in modulating immune factors involved in the recruitment of inflammatory cells in the intestine of animals infected with SE, favoring discrete modulation of the inflammatory process in this model.
Um motor para jogos digitais universais
(Universidade Federal de São Carlos, 2014-05-29) Garcia, Franco Eusébio; Almeida, Vânia Paula de; https://lattes.cnpq.br/0268728255033469; https://lattes.cnpq.br/2935753656974386
Digital games are being played gradually more for entertainment, leisure and as a tool for education. However, one does not observe an increase in gaming accessibility corresponding to the ascending importance and use of these software systems. Universal Design provides an alternative approach to design more usable and accessible solutions to as many people as possible, regardless of their physical, cognitive and emotional capabilities. The Universal Design for games is in its early stages: so far, only a few universal titles have been created. Those few games were designed following the Unified Design, a process which leads the game design to a more abstract and modality independent way. However, albeit aiding designing the game, the implementation is left to the developer. Game engines are software created to ease the development and the implementation of digital games. Hence, this work describes a game engine for universal games UA-Game Engine (UGE), which purpose is to ease the development of universal games. UGE explores data-driven, event-driven and entity component systems to ease the development of run-time flexible and adaptable games. This dissertation introduces the concepts of Abstract Game World, Concrete Game World, Meta-Game and Game. To achieve this result, this dissertation informally demonstrates that is it possible to construct a universal game by decomposing any game world into three elements: entity (actor), component and event. These elements are used to create an Abstract Game World without a user resulting into an input-output free Meta-Game. Afterwards, it is suggested that it possible to combine the three elements to reconstruct one or more Concrete Game Worlds from the Abstract Game World to suit the interaction needs of the users. With this result, the UGE game engine was developed. UGE uses an extensible and flexible user profile to, during run-time, tailor the Meta-Game into an accessible Game, by defining all the input and output interactions according to the user s interaction needs. Finally, it is described the evaluation and validation process, currently in progress the obtained results so far classify the project as promising.

(Universidade Federal de São Carlos, 2014-05-29) Hayashi, Ana Paula; Ganga, Gilberto Miller Devós; https://lattes.cnpq.br/9062191157466610; https://lattes.cnpq.br/0025664168663096
Qualitative studies show that Lean Manufacturing implementation in Small and Medium Enterprises (SME) is performed in an informal way. Within this context, the main goal of this paper is to investigate the most commonly used Lean Manufacturing practices that are being implemented within Brazilian SME’s companies. In addition, this paper also aims at presenting what is lean manufacturing in the view of SME in Brazil. The research method used in this paper was an exploratory survey. The results show that the studied companies use practices in a fragmented way, not having a holistic view of lean manufacturing which is considered as being one of the most important part of such philosophy. This represents an opportunity for the studied companies.
Microrganismos e substâncias antimicrobianas presentes em biofertilizantes para o controle de Phytophthora nicotianae
(Universidade Federal de São Carlos, 2014-05-29) Silva, Aline Caroline da; Kupper, Katia Cristina; https://lattes.cnpq.br/7900622063392740; https://lattes.cnpq.br/8211851564787698
Among the phytosanitary problems faced by citrus sector it is highlighted the root rot caused by Phytophthora spp. which affects all stages of development of the citrus trees. Preventive measures associated with chemicals are used to control the disease, but the problems arising from the intensive use of fungicides have increased the interest in developing alternative techniques aimed at agricultural sustainability, among them the use of biofertilizers . Because of these facts, this study aimed to: (i) assess the effect of microbiota and metabolites present in biofertilizers produced from aerobic digestion (BSA) and anaerobic (BSAN) of swine manure on the mycelial growth of P. nicotianae; (ii) determining the effect of the products on inoculate of P. nicotinae in soil and roots of citrus tree, (iii) observing the effect on germination of citrus rootstocks . The results obtained in this study showed that the existing microorganisms and metabolites in biofertilizers affected the development of the colony of P. nicotianae; biofertilizer produced by aerobic digestion of swine manure (BSA) had the best efficiency in the elimination of inoculum of P. nicotianae ; BSA at concentrations of 5 and 10% and BSAN at concentration of 10% favored the germination of mandarin Sunki in substrate infested by the pathogen. Moreover BSA at concentration of 5% had a promising effect on seed germination of Rangpur lime under the same conditions.
