Item type:Item, Melhoria dos processos de manutenção em prédios públicos(Universidade Federal de São Carlos, 2012-08-22) ;Carlino, Alex Elias ;Serra, Sheyla Mara Baptista ;https://lattes.cnpq.br/8528385567782505https://lattes.cnpq.br/9663590426279761To avoid the maintenance, in other words, to look for forms of avoiding the flaws and not of correcting them. This concept summarizes the current scenery of the function maintenance. It is known that the maintenance activities generate great earnings to the productive processes. Being like this, the maintenance contributes in an essential way to the conservation, valorization, increase of the productivity, in addition the lack of the same can generate great economical problems, social and environmental. Regarding the property maintenance, it is verified that this is still on this side of the ideal. The objective of this work is now it of evaluating the processes used in public entities for accomplishment of the activities of property maintenance. For this end, studies of the bibliography were accomplished related to the maintenance in addition case studies in three entities of the indirect public administration, located in the city of São Carlos/SP. The results obtained through the observations, ally to the bibliographical references contributed to map the processes now developed by the studied entities, in addition to identify the "bottlenecks", in other words, limitations of the efficiency capacity inside of the necessary processes for accomplishment of the services of property maintenance. Finally, some points for improvement of the installment of the services of property maintenance were proposed.Item type:Item, O discurso eleitoral da Folha de S.Paulo e O Estado de S.Paulo na campanha eleitoral de 2010(Universidade Federal de São Carlos, 2012-08-22) ;Orlandini, Romulo Augusto ;Azevedo, Fernando Antonio Farias de ;https://lattes.cnpq.br/6291864794986993https://lattes.cnpq.br/0134197554076226The objective of this thesis was to discuss the election of 2010 under the bias of print journalism. The analysis was made by the editorial in the Folha de S.Paulo and O Estado de S.Paulo. We had as hypothesis that newspapers represent concepts and ideas of the reading public medium that would influence the editorial published in the coverage of the three major presidential candidates. Then, we compare the final result of the election with the different approaches of the editorials in relation to candidates in order to know whether an editorial could influence the election or not. The theory was founded on the philosophy of language, concept and method created by Mikhail Bakhtin and based on ideological correctness of the text and context, relating the socio-historical moment. The theory was founded on the philosophy of language, concept and method created by Mikhail Bakhtin and based on the correlation of the text and ideological context, relating the socio-historical moment. The qualitative results showed that O Estado de S.Paulo quoted 14.02% of 442 collected texts cited presidential candidates, while the Folha de S.Paulo quoted presidential candidates in 22.8% of 285 texts - with the name appearing Rousseff on average 59 times, Jose Serra quoted 37.5 and Marina Silva quote 10.5. The qualitative result proved the trajectory of incandescent Election: Nine themes were prevalent in newspaper articles and revealed a complex scenario of the race to the presidency. We observed that the effect of former President Luiz Inacio Lula da Silva and political scandals have earned high relief - generating protests from editorial writers - highlighting the role of the press watchdog - to the point of the O Estado de S.Paulo first take position in an election. In the other one was related issues directly with the electoral rules, the relationship with government plans while the other (FARC, Abortion/religion and Privatization) resumed discourses that traditionally appear at critical moments in which it is called when it is necessary to trigger the review publicItem type:Item, Adoção de práticas de manejo da agrobiodiversidade e estratégias de diversificação dos meios de vida das comunidades rurais em Pirenópolis - Goiás(Universidade Federal de São Carlos, 2012-08-23) ;Mutadiua, Celso Américo Pedro ;Stolf, Rubismarhttps://lattes.cnpq.br/5120473662251086The agroecological principles applied on agrobiodiversity management have been seen as a strategic tool for sustainability in agro-ecosystems for rehabilitation of socioeconomic and environmental conditions and for food security purposes. The present research analyzes the adoption of these basic recommended practices on the agrobiodiversity management, considering livelihood strategies. For this purpose are analyzed twelve agricultural establishments, six under the PAIS (Integrated and Sustainable Agroecologic Program) and six out of the PAIS. In this context are identified by a hand, the strategies by which rural families opt for a set of agricultural activities, non-agricultural and social support capabilities to sustain themselves and survive the risks and environmental crises. On the other hand gives to know the main agroecological practices in use in the establishments and the bottlenecks in the process of adoption of agroecological transition. The results shows a positive correlation between the numbers of practices adopted based on agroecologic principles and the number of alternative income generating sources for the farmers.Item type:Item, Proposta metodológica de medição da resiliencia agroecológica em sistemas sócio-ecológicos: um estudo de caso nos Andes colombianos(Universidade Federal de São Carlos, 2012-08-23) ;Salazar, Alejandro Henao ;Schlindwein, Marcelo Niverthttps://lattes.cnpq.br/9690898537150950In the last tree centuries the capitalistic economic model introduced deep changes and with no precedents into the ecosystems with the aim to satisfy its own food demands, potable water, wood, fiber and energy. Those changes helped to improve the life of thousands of people, but at the same time weakened nature s regulation capacity. The most evident consequence is the actual threat of a world climate change, which causes a special worry between agriculture scientists once the agriculture could be seriously injured when climate and rainfall regime change, putting in danger food sovereignty in local and global levels. Maybe the most important found in the latest years were the revealing of many agricultures whom can deal with the climate variation and also prepare themselves to minimize the lost of income by using alternative cultural treatment. This study proposes a methodology to measure agroecological resilience in socio ecologic systems, comparing forms of agroecological cultural systems (a) within the conventional cultural systems(c). A technical team gathered with peasantries measured agroecological resilience indicators in agroecological and conventional properties in the central ridge of Colombian Andes. The selected indicators discuss: a) the characterizing of a climate event (threat), b) the estimative of vulnerability level, c) the sustainable agriculture technique capacity to response. This study identified resilience differences between agroecological and conventional properties, showing that agroecological treatments tend to show a bigger resilience capacity in face to climates risks. The definition and the identification of those capacities show the vii potential risk management from the approach to the response and adaptation capacity. And It is especially those peasantries with alternative cultural treatments that were able to deal, resist and recover from extreme meteorological events.Item type:Item, Desenvolvimento de protótipo de sensor de umidade cerâmico(Universidade Federal de São Carlos, 2012-08-24) ;Ito, Amadeu Rodrigues Pereira ;Souza, Dulcina Maria Pinatti Ferreira de ;https://lattes.cnpq.br/4100119317525940https://lattes.cnpq.br/4941893403738344Humidity sensor is a special type of gas sensor which is sensitive only to H2O molecules. It has a large variety of applications in industrial, household and agricultural equipments. Humidity ceramic sensors have been considered interesting due to their chemical and thermal stability. The lack of a national manufacturer of humidity sensors was the main motivation to accomplish this master thesis, whose objective was to develop a prototype of resistive ceramic humidity sensor. The objective was reached using Mn doped-MgAl2O4 powder, forming thin plates (650 a 750 μm) through tape casting process, appropriate sintering to obtain proper microstructure and the performance characterization of sintered plates as humidity sensor, especially with regard to sensibility and reproducibility. The tape casting process was successful for providing plates with excellent sensibility in the range 20-90% relative humidity and the response time of 120 and 20 seconds in the adsorption and desorption steps respectively. The correlation between the good performance and the porosity was established through the detailed interpretation of impedance spectra measured at several levels of humidity. Simultaneously to the porous plate preparation, it was developed a microcontrolled electronic transducer circuit with firmware written in C, which allows the immediate use of the electric signal produced by the humidity sensitive plate by a variety of equipments already available in the market. At the final step, the humidity sensor prototype was assembled through the insertion of the humidity sensitive plate, appropriately covered with silver electrode, to the electronic system.Item type:Item, Avaliação quali-quantitativa do fitoplâncton presente em reservatório de sistema de aproveitamento de água pluvial para irrigação(Universidade Federal de São Carlos, 2012-08-24) ;Corrêa, Thais Helena Prado ;Moruzzi, Rodrigo Braga ;https://lattes.cnpq.br/9408665052901005https://lattes.cnpq.br/0668892738076635The use of rainwater can be an effective alternative to minimize the use of water sources. Within this perspective, stormwater play a key role in planning and sustainable management of water resources as a substitute for the use of water for agricultural purposes, irrigation, residential uses such as watering flowerbed and garden, cleaning floors, sidewalks and playground and car wash. Agriculture is the major user of water in the world, according to the World Resources Institute, UN agriculture uses 70% of existing drinking water. In Brazil, 88% of drinking water is used by agriculture and 5% of Brazilian crops are irrigated and 55% of farmers use archaic methods that lose more than half of the water used. Thus, alternative techniques of water management for irrigation must be proposed and implemented to mitigate the conflicts generated by the deficiency of water considering the use of rainwater as part of a broader activity, related to the expansion of water supply. Therefore, one should consider rainwater as an alternative source to conventional sources and it should investigate the potential qualitative and quantitative agreement with the intended uses. In this work the intended use is irrigation of vegetable crops for research on sustainable agricultural management techniques were therefore investigated the existence of species of phytoplankton and physical and chemical analyzes made reservoir built in the Research Center of the city-Ipeúna-SP.Item type:Item, Zoneamento (geo)ambiental analítico da microbacia do Córrego do Rosário (Descalvado, SP)(Universidade Federal de São Carlos, 2012-08-24) ;Inêz, Eliezer Bernardes ;Lorandi, Reinaldo ;https://lattes.cnpq.br/7794241793056671https://lattes.cnpq.br/2337238348941685Adopting a river basin as a landscape management unit constitutes a major achievement in planning and management due to socio-environmental interactions and their unfoldings that take place in this area. Among the variety of environmental planning and management tools used in river basin contexts, (geo)environmental zoning is noteworthy in that it helps decision makers and aims at reconciling socio-economic development with environmental quality. Along these lines, the purpose of this study focused on the microbasin of the Rosário stream in Descalvado, SP, Brazil was to present an analytical (geo)environmental zoning proposal generated from a set of thematic mapping documents at a 1:10000 scale, field studies, and geo-technologies that seeks to analyze capacities and susceptibilities of this microbasin terrain in the face of urban occupation. Thus, the findings of this study can serve as a basis for discussion and construction of public policies capable of guiding a right and proper local urban expansion process.Item type:Item, Análise do controle autonômico cardíaco e do metabolismo muscular durante o exercício descontínuo dinâmico e resistido em homens jovens e idosos(Universidade Federal de São Carlos, 2012-08-24) ;Simões, Rodrigo Polaquini ;Silva, Audrey Borghi ;https://lattes.cnpq.br/4855616925791895https://lattes.cnpq.br/2731345085062145The thesis consisted of three studies described below. Study I, which aimed to investigate the effect of aging on kinetic responses of heart rate (HR) and oxygen consumption (VO2) during rest-exercise (ontransient) and exercise-recovery transitions (off-transient), and to investigate the influence of exercise intensity (mild and moderate) on the kinetic parameters of these variables. 28 apparently healthy men were evaluated, and 14 constituted the young group (YG) and 14 the elderly group (EG). The evaluation consisted of applying an incremental exercise testing of ramp protocol on cycle-ergometer (IET-R) to determine the maximum power (MP) and discontinuous exercise test on a cycle ergometer (DET-C), which started with an initial power load of 10% of MP with subsequent increase of 10% until exhaustion. Were recorded ventilatory and metabolic variables, the HR and blood lactate at rest and during exercise. The lactate threshold (LT) was closed between the groups (approximately 30% of MP). The EG showed higher values of the kinetic responses, both on and off transitions of HR and VO2 (p<0.05), and the values were higher in moderate compared to mild in YG (p<0.05). We conclude that the elderly have slower kinetic responses of HR and VO2 in relation to young and that at moderate intensity; the kinetic responses were slower in relation to mild intensity in young. Following, the study II aimed to investigate the behavior of the heart rate variability (HRV) responses during a discontinuous resistance exercise (RE) protocol and check whether they agree with the blood lactate responses in the determination of anaerobic threshold (AT) in apparently healthy young and elderly. For this proposal, in the same volunteers in the study I, was applied the test of one repetition maximum (1RM) on the leg press 45º and the discontinuous exercise test on the leg press 45 (DET-L), initiated in 10% of 1RM subsequent increments of 10% until exhaustion, and the HR and blood lactate were obtained at rest and during exercise. The AT was determined at approximately 30% of 1RM in both groups and both methods of analysis (blood lactate and HRV), the HRV index decreased with increasing load and stabilized from the load corresponding to AT in both groups, additionally the blood lactate remained practically stable until the load of AT, and increased significantly after this intensity. The EG had lower HRV values in lower loads of AT, and lower values of HR and blood lactate in loads above of AT in relation to the YG. We conclude that the HRV responses to determine the AT are according to blood lactate, and that the increase in load during the discontinuous RE promoted gradual vagal withdrawal followed by sympathetic activation in both young and the elderly, however, these responses are attenuated with the aging process. Finally, the study III, aimed to determine the AT during discontinuous dynamic and resistance exercise protocol by analyzing blood lactate and HRV in healthy older adults, comparing the cardiovascular, metabolic and autonomic variables between these two exercise modalities. We evaluated the elderly group of individuals during the tests: IET-R, DET-C, 1RM and DET-L. The AT within about 30% of maximum intensity in both the DET-C and DET-L by both methods (blood lactate and HRV). There were no differences in HRV variables between the modalities of exercise and a significant increase in systolic blood pressure and blood lactate after AT load in the DET-L. We conclude that HRV was effective in determining the AT and that the parasympathetic modulation responses were similar between dynamic and resistance exercise.Item type:Item, Estudos cristaloquímicos e teóricos de derivados do decahidrofenantreno(Universidade Federal de São Carlos, 2012-08-24) ;Machado, André Tivagus Lousada ;Schpector, Júlio Zukerman ;https://lattes.cnpq.br/4252331837170383https://lattes.cnpq.br/3662422395254441This work is a contribution to the study of the crystal, molecular and supramolecular structures as well as the conformation in vacuum of decahydrophenantrene derivatives. (4aS,4bR,7R,10aS)-3,7-Dimethyl-10a- (propan-2-yl)-1,4,4a,4b,5,6,7,8,10,10a-decahydrophenanthrene-1,4-dione (Compound 1) In this compound, C19H26O2, the A ring adopts a chair conformation, whereas the B and C rings both adopt distorted half-chair conformations with the quaternary C atom common to both rings lying 0.577 (3) and 0.648 (3) Å out of the approximate plane defined by the remaining five C atoms (r.m.s.deviations = 0.1386 and 0.1156 Å for the B and C rings, respectively). Molecules are assembled in the crystal through C—H…O interactions involving both carbonyl O atoms, which lead to supramolecular chains aligned along the b axis. (4R,4aS,4bS,7R,10aR )-4-Hydroxy-4a,7-dimethyl-2-(propan-2- yl)-1,4,4a,4b,5,6,7,8,10,10a-decahydrophenanthren-1-one (Compound 2) In this compound, C19H28O2, the A ring adopts a chair conformation, and each of the B and C rings adopts a distorted half-chair conformation with the methine C atom in the CH2C(H)C( O) residue, common to both rings, lying 0.6397 (19) and 0.6328 (18) Å out of the approximate plane defined by the remaining five C atoms (r.m.s. deviations = 0.0791 and 0.0901 Å for rings B and C, respectively). Helical supramolecular chains along the a axis mediated by hydroxy– carbonyl O—H…O hydrogen bonds feature in the crystal packing. (4R,4aS,4bS,5R,10aR)-4-Hydroxy-4a,5-dimethyl-2-(propan-2-yl)- 1,4,4a,4b,5,6,7,8,10,10a-decahydrophenanthren-1-one (Compound 3) In this compound, C19H28O2, the A ring adopts a chair conformation. Both the B and C rings adopt envelope conformations with the C atoms common to both rings and adjacent to the carbonyl and hydroxyl groups, respectively, lying 0.604 (3) and 0.634 (3) Å out of the mean planes defined by the remaining five C atoms of rings B and C, respectively (r.m.s. deviations = 0.0100 and 0.0157 Å, respectively). The formation of linear supramolecular chains along the a axis mediated by hydroxy-O—H…O(carbonyl) hydrogen bonds is the most prominent feature of the crystal packing. The calculated and crystallographic structures are shown to be similar so that, in this case, the intermolecular interactions and consequently the crystal packing has almost no influence on the molecular conformation.Item type:Item, As disciplinas de história da educação na UAB/UFSCar: possibilidades para a graduação em pedagogia e para a formação de professores(Universidade Federal de São Carlos, 2012-08-26) ;Batista, Aldrei Jesus Galhardo ;Bittar, Marisahttps://lattes.cnpq.br/0853894851232611This work aimed at understanding the role of the disciplines of History of Education of Pedagogy by Distance course from the Brazil Open University Program at the Universidade Federal de São Carlos, in his first four offers for the formation of educators. The theme chosen is justified amid a context of devaluation of formation courses such as Foundations of Education courses in Pedagogy before the postmodern paradigm of education in the world and in Brazil. I chosen to do the work guided by bibliography retrieval about the theoretical critical Works based on Dermeval Saviani, José Carlos Libâneo, Selma Garrido Pimenta, Bernadette Gatti, Elba Smith and Miriam Baker Warde, and legislation relating to formation courses and distance education and on the other count on statements from students, virtual tutors and teachers participating in the disciplines of History of Education I and II of the UAB / UFSCar in the search for the synthesis of multiple determinations of disciplines. Thus, the procedure followed was one that considers a singular phenomenon on its universal context in which both form an organic unity. I started from the resumption of the history of Teacher Formation and Pedagogy in Brazil and then to address the National Curriculum Guidelines of Teacher Formation and Pedagogy. The situation of Brazilian higher education in XXI century and with an emphasis on public policies for the growth of distance education, beyond to traditional models of distance education. Presented the situation of studies in History of Education as a field of science and reality (historical) in the disciplines of History of Education in formation courses and Pedagogy, and then present the disciplines within the context of Pedagogy course in UFSCar. Finally, you can find a resumption of all studies from the testimony of the participants with reference to the theoretical frameworks used in previous chapters. So, we can conclude that the UAB Pedagogy course / UFSCar, as well as their subjects of History of Education, constitutes positive experiences and are a reference for the formation of educators in the midst of a context in spite of the numerous problems that need to be overcome by distance education.Item type:Item, Caracterização de práticas de melhoria contínua e seus impactos : estudo de caso em uma empresa de bens de consumo(Universidade Federal de São Carlos, 2012-08-27) ;Segundo, Ronaldo Aparecido ;Oprime, Pedro Carloshttps://lattes.cnpq.br/9291517431456908Competitiveness of companies demands strategies that respond to competitive challenges in the organization. One way to address these challenges is related to Total Quality Management, in particular the continuous improvement of products, processes and management. In this way the literature shows some approaches and tools for the deployment of continuous improvement. Although it has been focused by several authors, the participation of people is still a critical factor for success in continuous improvement initiatives. But it was not fully evident in the literature the importance of collaboration and interaction of people during the programs and continuous improvement projects. As a result, the goal of this research is to investigate the importance of collaboration and interaction in the results and maintenance of continuous improvement programs. The research method it was a case study and the research was conducted in a consumer goods company with experience in implementing several programs of continuous improvement. Empirical evidence shows that the results and the maintaining continuous improvement programs are influenced by interaction and collaboration between individuals especially in the long term. This dissertation contributes to both organizational and for academia, for understanding the importance of interaction and collaboration between people can help correct the actions of organizational actors to better utilization of continuous improvement programs.Item type:Item, Avaliação da temperatura de indução e de fontes de nitrogênio na produção de proteína de superfície de Streptococcus pneumoniae em Escherichia coli recombinante(Universidade Federal de São Carlos, 2012-08-27) ;Santos, Mauricio Possedente dos ;Zangirolami, Teresa Cristina ;https://lattes.cnpq.br/4546701843297248https://lattes.cnpq.br/7270825006141856Diseases caused by Streptococcus pneumoniae are one of the main problems of public health in the world. The pneumococcal surface protein A(PspA) is a potential canditate as carrier in a conjugate vaccine against this bacteria. Considering the inherent high losses of the purification and conjugation steps, it is fundamental to adopt a strategy of cultivation and expression that allows the obtainance of large quantities of protein. Thus, the use of Escherichia coli as expression system as well as its cultivation in complex medium constitutes promising alternatives for reducing the cost and increasing the productivity of the process. The goal of this work was to study the influence of the temperature and cultivation medium composition over the production of a PspA belonging to clade 4 protein fragment (PspA4Pro) during rE coli cultivations, aiming at to evaluate the possibility of employing vegetable-based nitrogen sources (soybean protein hydrolisates) instead of the Triptona, an animal-derived nitrogen source. The experiments were carried out in both shakers and benchscale bioreactor, using a complex medium which contained glucose and glycerol as carbon sources, lactose as inducer and Soytone, Phytone or Triptone as nitrogen sources, besides yeast extract. Samples were collected during the experiments to follow the cell growth (measurements of absorbance, dry cell weight and permittivity signal from biomass sensors), the carbon sources consumption and the production of organic acids by HPLC analysis. The stability of the plasmid (agar plates with or without kanamycin) and the production of recombinant protein (Bradford and SDS-PAGE electrophoresis followed by densitometry) were also evaluated. Preliminary experiments were performed in shake flasks, incubated at 300rpm and 37ºC, employing both complex and defined media. The highest productivity was achieved in complex medium, with a 42% superior protein production. Subsequently, nine complementary experiments were conducted in shake flasks with complex medium, under the agitation of 300rpm and temperatures of 37ºC (growth phase) and 25, 31 or 37ºC (induction phase). The largest specific production of soluble PspA4Pro was verified at 25ºC, reaching, respectively, 209±6, 192±5mg/g dry cell mass for Phytone and Triptone, with final absorbance values (after 12h of induction) of 9.0±0.4 and 8.5±0.4. The best protein production for Soytone (124±4mg/g dry cell weight) was observed at 31ºC, yielding a final absorbance 8.0±0.4. From the results obtained in the preliminary tests, the nitrogen source Phytone was selected for experiments in bioreactor. Four batch cultures were conducted in bench-scale bioreactor (5L), containing a modified auto-induction complex medium (10g/L glucose, 60g/L glycerol and 20g/L lactose), being three of them with Phytone and one with Triptone, for comparison. The best results in terms of protein production (245±7mg of PspA4Pro soluble/g dry mass) were obtained in the presence of Phytone, corresponding to an increase of 16% towards the maximum value achieved in the cultivation with Triptone. These results demonstrate the potential of vegetable-based nutrients as alternatives to animal-derived nitrogen sources in complex media, contributing to adequate these media formulations to the current guidelines of good manufacturing practices.Item type:Item, Gestão financeira e econômica da propriedade rural com multiproduto(Universidade Federal de São Carlos, 2012-08-27) ;Osaki, Mauro ;Batalha, Mario Otávio ;https://lattes.cnpq.br/1015001063418091https://lattes.cnpq.br/9357773852218630Farmers have always neglected management procedures in their enterprises in detriment to initiatives regarding production technology. Overall, producers and technicians know the answer to what, how and when to produce, but they don t know the cost or profitability of this technology. The present study shows the importance of the sustainability of agricultural enterprises with reduced governmental intervention and the risk involved in a double crop production system. Therefore, the aim is to propose a model to support the decision-making process, focused on production planning in a representative multi-product farm under conditions of risk. Using quantitative applied research, a theoretical model of agricultural planning was combined with operational research to explain and understand different allocations of resources within the decision-making process. For that purpose, two production regions of Mato Grosso state in Brazil were selected: Sorriso (SRS) and Campo Novo do Parecis (CNP). In SRS, a production system with 76.9% early soybean (SP) and 23.1% soybean (SN) for the first harvest and 76.9% corn (MS) for the second harvest generated a high gross margin and risk. On the other hand, a production system with 90% SN and 10% SP implied less risk. Diversifying the cultivated area with SP and SN in the first crop and MS in the second crop is interesting for farmers; however, land allocation decisions depend on how much risk the producer is willing to take. Since this farm planning strategy reduces SP and MS areas in the production system, gross margin and risk are also decreased. The following distribution of arable land produced the maximum gross margin value in CNP: 62.5% SP, 18.8% SN and 18.7% cotton (ALG) in the first harvest and 62.5% MS for the second harvest. The resulting maximum gross margin of the farm was R$754,260.77, which was R$122,525.78 under high risk conditions. As the area of cotton production is reduced, the representative exposure to risk is protected. In this case, a production system with multiple products does not exactly mean reduced risk for the farm, since the addition one particular product in the production portfolio generates a specific cost, called the sunk cost. Thus, a production system becomes feasible when the use of specific machinery and equipment is maximized, but in the end this procedure penalizes the performance of other products. The decision to allocate land for these products should remunerate the opportunity cost of soybean and corn. The efficient frontier curves correspond to the most efficient investment strategies for the two farms.. The frontier curve for SRS was the allocation of average land used in the last six seasons (2004/05 to 2009/10), showing that the production system adopted (32.5% SP and 67.5% SN for the first crop and 32.5% MS for the second crop) has productive efficiency to minimize risks for a certain income level. This decision corresponds to an aversion rate to risk of 1.05. In the case of CNP, the average combination of crop area used was very close to the efficient frontier curve, indicating that the farm planning production system with 28% SP, 54% SN, 18% ALG for the first harvest, and 28% MS for the second harvest also minimizes risk for a certain income level. On the other hand, the aversion rate to risk corresponds to 3.71.Item type:Item, Programa de Aquisição de Alimentos (PAA) da agricultura familiar no município de São Carlos: impactos socioeconômicos nos agricultores familiares beneficiários(Universidade Federal de São Carlos, 2012-08-28) ;Rossi, Fabiana Ribeiro ;Souza Filho, Hildo Meirelles dehttps://lattes.cnpq.br/3203702000103304The Food Acquisition Program from Family Farm (PAA) was created in 2003, within a group of policies with structural significance of the Zero Hunger Program, in order to promote actions in the scope of agricultural policies and food security. Its operation is made through modalities that purchase products from family farmers, without bidding. The PAA, since its institutionalization, has been the focus of several analyzes, as their impacts on the family farmers beneficiaries. This dissertation aimed to evaluate the impacts on family farmers beneficiaries of the Direct Purchase Local with Simultaneous Donation (CDLDS), executed since 2006, in the city of São Carlos, by the Municipal Agriculture and Food Supply (SMAA). The data collection was done by applying a structured questionnaire to a representative sample of 30 beneficiaries of the program in São Carlos and adjacent municipalities. The data were analyzed using descriptive statistics and hypothesis testing, which allowed the identification of positive impacts of the program in aspects related to their life conditions, land use, crop production, commercialization of products, agricultural income, association, family assets, investment properties, access to rural extension and information, agricultural practices, quality management, among others. No significant impacts were identified in aspects related to property management techniques and production, access to rural credit, participation of women, among others. The PAA can be considered an important program for family farmers beneficiaries because it is an alternative market channel to sale the production, collaborating, through its set of actions, with a more sustainable inclusion of its beneficiaries in other markets.Item type:Item, Reminiscência e dialética no diálogo Fedro de Platão(Universidade Federal de São Carlos, 2012-08-28) ;Müller, Nestor Reinoldo ;Souza, Eliane Christina de ;https://lattes.cnpq.br/5658382257368048https://lattes.cnpq.br/7145572432457857This dissertation aims to investigate, in Phaedrus text, the concepts of recollection and of dialectic, in order to explore some hypothesis of possible relation between them. The inquiry of the first concept is accomplished in the second section of the dialogue, where recollection reveals itself as an experience of access to the essential realities on the intelligible level. The research discriminates three aspects of recollection and seeks to analyze their implications to the main question represented by the connections between the sensible and the intelligible levels. The study of dialectic proceeds from de distinction among a wider and original sense of the word, denoting the conversation through questions and answers on any one subject, and the more precise and systematic sense developed by Plato, signifying the operation of synthesis and analysis. The research examines the entire dialog but privileges the six descriptions of dialectical technical procedures that can be found in the third section, presented as a new method to a real rhetorical art. Giving attention to some signs of approximation and some fields of convergence between recollection and dialectic, the dissertation raises four hypothesis aiming at possible intersections between the two concepts.Item type:Item, A função social e a refuncionalização do território ferroviário da Cia Mogiana em Ribeirão Preto(Universidade Federal de São Carlos, 2012-08-28) ;Zamboni, Débora Prado ;Falcoski, Luiz Antonio Nigro ;https://lattes.cnpq.br/3200660670856698https://lattes.cnpq.br/5585378083851286This paper investigates the relationship between the railroad present in Ribeirão Preto and urban organization of this township. Its principle the importance of the use of public assets in minimizing social inequalities from the use of part of the heritage of the Brazilian railway network, the non-operating properties, present in Ribeirão Preto in the perspective that all property should fulfill its function given the social regulation of urban policy in Brazil. Contrary to this end it is important the historical fact of the heritage railway in Ribeirão Preto have been mainly used for the consolidation of routes in the city, urban decision that gives value to certain areas of the municipality. This paper investigates the enhancement of areas of the county through the use of rail assets, whether public or private. Finally, it appears as if nowadays gives the relationship between the urban municipal legislation and the use of what is now public property rail in reducing social inequalities. As a goal, it is expected to act positively on the stage of understanding and minimizing social differences in urban space.Item type:Item, A aprendizagem cooperativa nas aulas de matemática : uma experiência nas turmas de 8º e 9º anos(Universidade Federal de São Carlos, 2012-08-28) ;Gouvêa, Mariangela Salviato Balbão ;Sampaio, João Carlos Vieira ;https://lattes.cnpq.br/8286887389013685https://lattes.cnpq.br/6105754049240250The objective of this study is to establish whether mathematical activities, prepared based on cooperative learning, produce changes in how students learn and confront with mathematics. Thus, were designed, developed and analyzed six math classes cooperatives, which occurred in an 8 and a 9 th grade of elementary education at a private school. The proposed group of activities consists of mathematical problems written in the form of clue cards. Each group receives an envelope containing six cards, which must be distributed among team members. To solve the problem all students must contribute explaining their clues and sharing ideas. The teacher provides various materials to support the activities such as ruler, squares, compasses, paper, scissors, calculators, colored cubes, dice, straws, beans, charts etc. The results obtained by each group are described in the answer sheets, previously prepared by the teacher. Before and after cooperative classes, a questionnaire was applied in order to know the opinion of students about group work and their skills in mathematics. The results achieved with the cooperative activities were fruitful discussions on mathematical concepts and their properties, greater clarity from teachers regarding students' mathematical difficulties, greater social involvement, respect for ideas and opinions of group members, ability to represent mathematical situations by using concrete materials, drawings, graphics and text.Item type:Item, Uma ontologia evolucionista: considerações sobre a noção de "desenvolvimento" na obra de Darcy Ribeiro(Universidade Federal de São Carlos, 2012-08-28) ;Moreira, João Paulo Aprígio ;Lanna, Marcos Pazzanese Duarte ;https://lattes.cnpq.br/8355559441138016https://lattes.cnpq.br/5542752158910620This work investigates possible relations between a modern anthropological theory and discourses about "development". These relations are presented in theories of cultural change which will be consider with focus on the role mediators play in the production of specific meanings to the notion of "development". The analysis focus on Darcy Ribeiro´s 'The Civilizing Process: stages of sociocultural evolution', published in 1968. In thhis book Ribeiro presents his theory articulating a neoevolucionist anthropological perspective with a project of development for the Brazilian nation based on the concept of "technological revolutions". This concept is one of the foundations of Ribeiro's idea of cultural change at the same time offers a critique of dependency theory in Latin America, in the form of placing in th epolitical field debates on the underdevelopment-"Development" constrast. From the concept of technological revolutions, Ribeiro returns to the issue of cultural dynamics, dear to the theories of modern anthropology and grounded in an evolutionary perspective, as well as to the values of the national-developmentalism defended by Labour politicians - values that reside in the critical dependence of Latin countries' economic and the search for political autonomy, as well as in the defense of nations "underdeveloped" as the path to development.Item type:Item, A política de governo eletrônico no Brasil: uma análise dos governos FHC e Lula(Universidade Federal de São Carlos, 2012-08-28) ;Mantovane, Solange AparecidaCapella, Ana Cláudia NiedhardtThis dissertation is proposing to make an analysis on how Information Technology and Communications became part of the structure of state administration in Brazil, taking into account their different stages of merger and consolidation in the context of the restructuring of the state late twentieth century. Specifically, it is to examine how the use of Information Communication Technologies was incorporated into the routine of public administration and translated into the creation and development of a policy for electronic government (or e- Government) in the period extending from first mandate of Fernando Henrique Cardoso to the last term of the government of Luis Inacio Lula da Silva. This analysis is done through a historical reconstruction of what has to be such a policy, covering all phases of development, beyond the key actors for implementation. We assume that the analysis of influence of theses mechanisms is fundamental to understanding the path that takes politics in this country. From this we make a balance between the two government studied in order to check the continuities, innovations and setbacks of e-government policy in the period. This balance is organized from the checklist used by Chahin (2004), is based on best global practices of e-government, and includes the following dimensions: leadership and coordination, policy formulation and evaluation, cultural environment, infrastructure and standards.Item type:Item, Efeito da imunização com enzimas recombinantes do metabolismo de nucleotídeos de Schistosoma mansoni sobre o desenvolvimento da esquistossomose mansônica experimental(Universidade Federal de São Carlos, 2012-08-29) ;Neris, Débora Meira ;Anibal, Fernanda de Freitas ;https://lattes.cnpq.br/4918261968772806https://lattes.cnpq.br/8420021026488937Schistosimiasis mansoni is a neglected chronic parasitic disease that affects thousands of people worldwide, caused by the trematode Schistosoma mansoni. In the infected host the disease is characterized by the presence of granuloma, imunnopathological response of the cellular infiltration against egg antigens. Thus, the host-parasite relation favors hepatosplenomegaly, acite and hepatic fibrosis. Current chemotherapy is based on the use of Praziquantel (PZQ), used against all species of Schistosoma spp for over 30 years. The main issue is that the PZQ is practically inactive against immature schistosomula and favors the resistance growth of the existent lineages, which makes the study for new drugs and vaccines that can contribute to the control of this disease even more urgent. One of the paths on the search for new therapeutic targets is the study of essential enzymes to the S. mansoni. In particular, it is known that the enzymes Adenylate Kinase 1 and 2 (ADK), Uridine cytidine Kinase 1 and 2 (UCK), Hypoxanthine guanine phosphoribosyltransferase (HGPRT) e Purine nucleoside phosphorilase 1 (PNP) are found on the metabolic pathways of the parasite s nucleotide, participating in the metabolism of purines and pyrimidines. Our goals in this study were to assess the immunization with these enzymes, using the S. mansoni cercariae infected murine model, and subsequently analyze the acting in oviposition and growth of adult worms. Our results showed that the immunization in Balb/c mice with the UCK enzyme was capable of inducing a specific immune response, which favored a significant reduction of the parasitic load (adult worms). However, it was not possible to observe significant reduction in the number of eliminated eggs. Regarding the immunization with PNP and HGPRT enzymes, the mice had a reduction in the number of eggs per gram of feces. The data obtained are considered interesting and can be new targets for immunotherapy against schistosomiasis mansoni. Thereby, new assays must be made with different dosages of the enzymes for a better assessment on how these enzymes modulate the parasitic load through the eggs reduction, reduction in the adult worms retrieving, as well as the antibody levels during the murine infection by the S.mansoni.
