O Brasil é o primeiro produtor mundial de citros e o maior exportador de suco concentrado de laranja - principal produto do complexo agroindustrial da citricultura brasileira. O cultivo da laranja também é o mais importante do Brasil, entre as espécies frutíferas. A cultura da laranja é distribuída desigualmente no Brasil, concentrado um pouco mais de 70% no Estado de São Paulo, e o restante distribuído nos estados: Sergipe, Bahia, Minas Gerais, Paraná e Rio Grande do Sul. Possuindo o Estado de São Paulo mais de 80% da capacidade de processamento, dado esse fato o motivo do foco neste estado. A laranja existe no Brasil desde o tempo da colonização, mas foi em 1930 que essa cultura adquiriu importância comercial. Neste trabalho estão delineadas as etapas da citricultura brasileira e a formação do complexo agroindustrial paulista, tendo em vista os produtores agrícolas e os processadores industriais, destacando a influência do mercado internacional no seu desenvolvimento. No capítulo 1 é feito uma discrição da trajetória da laranja pelo mundo até a sua chegada ao Brasil, no início era apenas para a função de reserva de vitamina C, a partir disso desenvolveremos a sua história no Brasil, sendo no início destinado para o comércio da laranja “in natura”, e depois de constituído o complexo agroindustrial ocorre a sua destinação às empresas processadoras, todo esse desenvolvimento apoiado no mercado internacional. No capítulo 2 apresentamos a estrutura na agroindústria citrícola, a caracterização deste setor, e as relações entre os setores através de contratos de compra e venda de laranja. No capítulo 3 são analisados os processos de fusões e aquisições das empresas processadoras de laranja, e um estudo de caso do município de Matão, mostrando a influência da agroindústria no desenvolvimento socioeconômico nos municípios por onde passaram

Technology always advances and thus the device miniaturization and improved performance, besides multifunctionality, they become extremely necessary. A wave of research on the area tends to grow in number and importance in today's market, it is necessary to search for new materials, new applicability of the existing ones and new processes for increasingly cheaper costs. Dielectric materials are considered a key element in this sector being the main electrical properties its high dielectric constant and low dielectric loss. The Polymeric Precursor Method appears as a good alternative because is a low cost, simple process with controlled stoichiometry. In this method, two steps were performed. In a first step, the precursor solution was decomposed into powders and in a second step the precursor solution was converted in thin films. In this work, was used the polymeric precursor methods to get thin films where they were heat treated and characterized by XRD, SEM and AFM. We have obtained Bi3NbO7 thin films with good homogeneity and uniform distribution of grains were noted. We observed that the best condition to obtain the tetragonal phase is annealing the film at high temperatures for a longer soaking time and with excess of bismuth. Several oxides electrodes were evaluated aiming to obtain textured dielectric thin films

The study takes as its object the evaluation process of a graduation discipline at the School of Arts, Sciences and Humanities, University of São Paulo (USP), developed through the methodology of Problem Based Learning (PBL). We consider three distinct and complementary aspects: procedural review (partial and final) student peer assessment and self-assessment. The sample consisted of 17 students from the undergraduate courses. Data collection occurred in two stages through questionnaires with open and closed questions. The qualitativeinterpretative analysis allowed two comparisons: cross (intra-step) and longitudinal (inter-steps). The results point to a trend of students evaluating objective aspects of the work as well as to overcome some difficulties in the development of the project.

This study aims to conduct an analysis on the social aspects present in the works of the Argentine economist Raúl Prebisch (1901-1986). Based on the author's research on the economic development of the peripheral countries, it will be demonstrated how the social and economic factors have interconnected in the developmental theory of the peripheral worldwide economy. To achieve this goal, the six works of Prebisch considered essentials by Economic Commission for Latin America and the Caribbean (ECLAC) were used as main bibliographic axis. Such texts are: Introduction to Keynes, The Economic Development of Latin America and Its Principal Problems, Economic development or monetary stability: the false dilemma, Towards a Dynamic Development Policy for Latin America, .Change and Development: Latin America's Great Task, Capitalismo periférico: crisis y transformación, Five stages in my thinking on development. Firstly the topics essential to economic development according to the author will be exposed, such as industrialization of peripheral countries as a means of raising the income of masses and the way it should be coordinated beyond the theoretical author's choice on historical events, the evolution of the deterioration of terms of trade between peripheral and central countries and the need for productivity gains to increase the income of the worker. Afterwards it will be exposed how such terms align with social inequalities and which definitions are incorporated by the author on the subject

This study aimed to develop, implement and evaluate the performance of a new type of bioreactor for anaerobic treatment of wastewater using different filling materials like trickling filters post-reactor. This bioreactor has mixed characteristics of the UASB reactors and horizontal flow from the point of view of removal of BOD (Biochemical Oxygen Demand) ssed (settled solids), TS (Total Solids), SS (Suspended Solid), SD (Dissolved Solids) and turbidity. The experimental model consists of a bioreactor with a volume of 12 m³, 2/3 filled by fluidized bed and 1/3 for fixed. The fluidized bed is made of polystyrene plates used as a system percolation and compartmentalized trickling filters, where each compartment was filled with a support medium with different characteristics (gravel number 4, plastic rings of polystyrene, PET and HDPE) . In addition, the output of a filter system was installed three entries filled with activated carbon. The bioreactor was installed in private residence in the city of Igarapava-SP (20° 02'40.18"S and 47° 45'01.36" W). The system was highly efficient as the removal of organic contaminant load 92% on average reducing the BOD, a significant result when compared to other anaerobic systems. For the other parameters, the mean reduction was 96% for turbidity, 99% ssed, 67.5% ST, 57% SD and 88% of SS. As for its operation the system was capable of operating in continuous flow without the need for maintenance during the entire period of evaluation and without energy, as it operates taking advantage of the natural slope of the terrain where it is installed. The environmental impacts were minimized due to the preservation of local vegetation allowing the ecosystem to remain unchanged beyond the prototype was completely sealed preventing exhalation of odors and therefore not causing inconvenience to neighboring populations. Given these facts it was concluded that the prototype is shown to be highly feasible deployed as a new alternative for treatment of sewage in rural and urban settings (individual homes, condos, farms, ranches, etc.) Due to ease of design and operability, and sustainability at all stages of execution.
