The aim of the work was to analyze the effectiveness of the Family Farming Food Acquisition Program for family farming in the municipality chosen for study, Angatuba/SP. The main aim was to understand the effects of the implementation of public policy for farmers during the period from 2011 to 2017, the period in which it was active in the municipality, and finally to understand the effects of the suspension of new institutional purchasing projects via PAA for families of previously benefited producers.
Desenvolvimento de um novo protocolo sequencial três etapas para a síntese de 1,2,3-triazóis 1,4-dissubstituídos assistida por irradiação de micro-ondas
(Universidade Federal de São Carlos, 2019-12-11) Silva, Everton Machado da; Schwab, Ricardo Samuel; https://lattes.cnpq.br/6935890756504964; https://lattes.cnpq.br/1506429039505519
Heterocyclic compounds has received a great attention in the branch of synthetic chemistry due to their wide field of applications, and among these, 1,2,3-triazoles are highlighted. In this work, a new three-step sequential protocol for the synthesis of 1,2,3-triazoles-1,4-disubstituted was developed using reactions under microwave irradiation. The reaction procedure aims at the combination of 3 sequential steps: a cross-coupling reaction of Sonogashira, followed by a deprotection reaction for formation of the terminal alkine and a 1,3-dipolar cycloaddition reaction catalyzed by copper (I) to obtain the 1,2,3-triazoles-1,4-disubstituted. The starting material used was 2-methyl-3-butin-2-ol, also known as MEBINOL, which has a much lower cost when compared to the analogue, trimethylsilacetylene. The deprotection stage represented an obstacle to be overcome in this reaction, considering that the reactivity of the substrates used proved to be extremely susceptible to the electronic nature of the substituents located in the aromatic ring. When electronic density removal groups were used, the 1,2,3-triazoles-1,4-dissubstituted were obtained with yields up to 74%. However, when electron donor groups were used, there was a significant reduction in yield. It is important to mention that for these cases the increase in the temperature of the reaction did not result in any increase in yields. The results which the development of a new three-step sequential procedure for the synthesis of 1,2,3-triazoles-1,4-disubstituted will be presented in detail. It should be noted that the sequential procedure directed at reducing the generation of residues from the purification of the intermediates, as well as at the possible loss of the terminal alkines generated in the deprotection stage, which in their majority are relatively volatile. Finally, it is important to mention that the use of microwave irradiation has reduced the reaction time involved in the three stages, contributing to increase the sustainability of the synthetic route.
Filo Arthropoda: abordagem do tema pelos livros didáticos das escolas públicas de Limeira, SP
(Universidade Federal de São Carlos, 2019-12-11) Xavier, Jessie; Fujihara, Ricardo Toshio; https://lattes.cnpq.br/1863735094370774; https://orcid.org/0000-0003-2776-5559; https://lattes.cnpq.br/8760808023949730
The Phylum Arthropoda constitutes a complex group of invertebrate animals with a wide distribution in environments worldwide, forming the animal kingdom's phylum with the highest number of representatives. In the teaching of Biology, as well as other disciplines, the textbook (TB) remains an important resource for presenting various themes to students, including the "Phylum Arthropoda" of invertebrate beings. Considering the issues surrounding the use of textbooks in the teaching of Science and Biology and the importance of arthropods in various aspects, this study aimed to analyze the treatment of the Phylum Arthropoda in Biology textbooks used by the state public school system in the city of Limeira, SP, and the possible influences of these materials on student learning. For this purpose, ten schools were selected using a sampling method based on regions of the municipality. In total, the educational institutions had six different collections of textbooks in the field, which were analyzed in two ways: first, quantitatively, considering the allocation of pages for the theme, and then qualitatively, through content analysis, following specific criteria. The results suggest some difficulty in generalizing regarding the quality of textbooks, as each criterion of analysis alternated between positive and negative highlights. However, there are reasons to believe that the "Ser Protagonista" and "Biologia Hoje" collections have more positive aspects than other collections, considering the analyzed criteria. On the other hand, the "Biologia - Unidade e Diversidade" collection showed more points to be improved. Studies like this emphasize the importance of a solid initial and continuous training of teachers so that they can have a critical capacity for the selection and use of textbooks in Biology classes, aiming for better results in the teaching and learning process.

(Universidade Federal de São Carlos, 2019-12-11) Mascarenhas, Fernando Júnior Resende; Christoforo, André Luis; https://lattes.cnpq.br/7623383075429186; https://lattes.cnpq.br/7101617534129526
Bridges and viaducts are important in the social and economic dynamics of a nation, and they are very important elements in transportation systems. In Brazil, freight transportation is predominantly by road. Therefore, viaducts and bridges are directly affected by the predominance of the road matrix. In recent years there has been an increase in the flow and weight of vehicles commuting on highways, which requires special attention to the structural performance of bridges and viaducts. Among the several structural problems to which these structures are susceptible, the longitudinal reinforcement fatigue deserves attention, especially in view of the increasing number of heavy vehicles. In spite of the heterogeneity of the real vehicles that travel in bridges and viaducts, the different national and international standards of mobile loads for bridges and road viaducts have their respective load trains for the dimensioning of such structures. The Brazilian Standard, NBR 7188:2013, has the TB 450 as its load train whose configuration represents a type vehicle of 450 kN. Based on that, this dissertation aims to analyze the fatigue in concrete and longitudinal reinforcement of beams of theoretical models of reinforced concrete bridges consisting of two, three and five beams. This estimate is made by considering the actual number of heavy vehicles from 2 to 6 axes of road stretches in the state of São Paulo over 9 years of data. Thus, the objective is to estimate the accumulated damage due to fatigue in concrete and longitudinal reinforcement; estimate the fatigue life of concrete and longitudinal reinforcement of bridge beams with different lengths; evaluate the deleterious impacts of fatigue on the different bridge lengths and built with two, three and five beams; to evaluate whether two-girder reinforced concrete bridges are recommended for design on high-traffic highways and to analyze whether the fatigue check indicated by the Brazilian standard using the Brazilian standard train is capable of representing the flow of real heavy vehicles. The methodology of this research is based on literature review about the phenomenon of fatigue and the necessary calculation procedures. These calculations will be performed using analytical methods and the use of Ftool to determine bending moments due to permanent and mobile loads in the span of the beams analyzed. For the calculation and verification of fatigue, theoretical bridge models with two, three and five beams with spans L of 10, 15 and 20 meters (m). In addition, two calculation scenarios are considered, where in Scenario 1 only the loads of 2 to 6 axle real vehicles are considered; and in Scenario 2, in addition to the actual vehicle loads, the 5 kN/m2 distributed load representing vehicles that can travel on the back and front of the analyzed vehicles is considered. Based on this, at the end of this project the following conclusions were found. The fatigue damage values calculated for the concrete were small and, thus they were considered negligible in all models analyzed in both Scenarios 1 and 2. As described in other studies found in the literature, the deleterious effects of fatigue are more noticeable in the longitudinal reinforcement than in the concrete itself. Thus, the fatigue life found for the longitudinal reinforcement deserves attention because in some cases it is less than the average design time of 75 years. In addition to this, the increasing of the gap makes the bridges have longer fatigue life. In addition, 5-beam bridges proved to be the longest in life, and 2-beam bridges are not recommended for locations with heavy truck traffic. Finally, it was found that the Brazilian normative type train is able to represent the current traffic of heavy vehicles.

(Universidade Federal de São Carlos, 2019-12-11) Sato, Humberto Domingues Thiago; Rezende, Alex Carlucci; https://lattes.cnpq.br/4190869482260889; https://lattes.cnpq.br/1166184740731058
In this monography, we study polynomial functions, starting with a brief historical research about how the general solutions of the first to third degree polynomial equations were constructed, then we proceed to analyze the important points that the National Curricular Parameters stand out in relation to the teachings of algebra and polynomials. In the development of the work, we also address the demonstrations of the Fundamental Theorem of Algebra (analytic and algebraic proofs) and the demonstrations of the general solutions of the polynomial equations up to degree three by means of radicals. Finally, some activities are introduced to be applied in the classroom in order to improve the teaching and learning process through Geogebra computational software. We apply one of these activities in a classroom and we discuss the results.

(Universidade Federal de São Carlos, 2019-12-11) Pedrosa, Luiza; Cabello, Janaina; https://lattes.cnpq.br/4349074907357325; https://lattes.cnpq.br/7486142193021846
This paper presents and discusses the performance of a team of translators / interpreters of Libras (TILS) in a course offered to the community and which aims to bring information to groups of women through training on their rights. The course is offered in a city in the interior of the state of São Paulo and is held weekly, involving different themes that are interconnected to the daily life of the female community (such as, for example, women's health, protection against domestic violence and legal guidance). When the meeting became accessible to deaf women, the work of the TILS team came into question, which began to operate in a context that we characterize here as a community. Therefore, with this qualitative research, it is intended to present the organization of the TILS team active in the weekly meetings of this course, presenting and questioning the need for prior and subsequent organization of the interpretation team considered more appropriate for the work to be developed, investigating the strategies adopted by this team.
Os usos da forma de tratamento de segunda pessoa singular “vos” entre os estudantes na Universidade de Nariño – Colômbia
(Universidade Federal de São Carlos, 2019-12-11) Caliri, Izabel dos Santos; Yokota, Rosa; https://lattes.cnpq.br/9230517686993400; https://lattes.cnpq.br/6927634435188516
El tema de esta investigación es el uso de la forma de tratamiento en la segunda persona del singular vos entre los estudiantes de la carrera Lengua Castellana y Literatura del 3er. semestre de la Universidad de Nariño (UDENAR) en Colombia. Nuestro objetivo es identificar como esos estudiantes utilizan el vos para comunicarse en contexto informal. En cuanto a la base teórica, para comprender la evolución de los pronombres de tratamiento fueron consultadas varias obras en especial, para entender las variedades de las formas de tratamiento en Colombia, Montes Giraldo (1967), Fontanella de Weinberg (1999), Calderón Campos (2010), Jang (2013, 2015), RAE (2014) e Rodríguez (2014). Nuestro estudio metodológico fue de paradigma cualitativo. La recolección de datos fue realizada a través de grabaciones en audio de un grupo de estudiantes universitarios en situaciones espontáneas. Enseguida a la transcripción del material grabado, se hizo el contaje del uso de las formas de tratamiento y la clasificación cuantitativa y cualitativa de acuerdo con los contextos y características de cada participante, ya que no es posible establecer generalizaciones en razón del universo de participantes de la investigación. Como resultado, identificamos que el uso de vos es bastante híbrido en la charla de los participantes y que el uso del voseo a través del habla espontánea entre los participantes representa estrategias de cortesía positiva o de solidaridad. Además, detectamos que el vos es más frecuente que tú cuando los participantes quieren presentar cercanía y confianza.
Imageamento magneto-ótico quantitativo em filmes finos supercondutores bicamada e com gradiente nanométrico de espessura
(Universidade Federal de São Carlos, 2019-12-11) Pinheiro, Lincoln Brum Leite Gusmão; Motta, Maycon; https://lattes.cnpq.br/8340540626164812; Ortiz, Wilson Aires; https://lattes.cnpq.br/0241177338066307; https://lattes.cnpq.br/3237585169182345
Vortex matter in superconductors has been the focus of research of both theoretical and experimental groups around the world. When developing superconducting devices patterned on thin films one should bear in mind that flux avalanches might occur for some materials at a certain range of applied fields and temperatures. For example, technological applications of NbN thin films may be threatened by the occurrence of magnetic flux avalanches of thermomagnetic origin appearing in a large portion of the superconducting phase. This work deals, in parallel, with two distinct superconducting thin film systems by the technique of quantitative magneto-optical imaging: A bi-layered specimen composed by overlapped layers of Nb and NbN and wedge-shaped superconducting thin films of V3Si and Pb. AC susceptibility and DC magnetometry were used to characterize both the single and multiple-layer films. Magneto-optical imaging reveals interesting features of the dendritic flux avalanches in the bi-layer system, including halo-like patterns around them, and crossing avalanches. The wedge-shaped systems opened a new way to tune the critical current in the film and allowed us to study the resulting changes in the flux penetration patterns along the film. The observation of flux avalanches reported here implies that, as usual, attention to this feature must be given when films with variable thickness and bi-layers are envisaged for possible applications.
