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

Water is one of the main inputs in agribusiness and is traded indirectly through the sale of agricultural products such as orange (juice or fresh) and cane sugar (ethanol and refined sugar). This study aims to estimate the proportional mass of water present in the products exported in the form of agricultural commodities considering the amount of water incorporated into the product in its genesis by plant photosynthesis, reinforcing a reflection on virtual and real water export, as well to indicate subsidies to management, planning and taxing of water resources

With the market more and more disputed and negotiations where the customer is the main factor who decides whether the companies have conditions or not to dispute the market, industries must search improvements in products and processes targeting lower costs and better quality. With that in mind, this work will study the actual situation of a line of Tension Leveler, after cold mill process, for aluminum coil, and search new technologies, precisely the Scrap Baller machine, which will raise the quality level and the line’s productivity. It will be analyzed the justifications (reasons) for these new technologies, the history, the involved concepts, the operation, functions, the material that will be tension leveled, the limitations and tech and economic viability in comparison with the actual system. Also it will be taken a brief about the aluminum coil production in Brazil, especially the ones which destiny is aluminum beverage can, and the recycling process, that is very well done in Brazil, worldwide leader in aluminum recycling

O cultivo de citrus é uma das principais atividades agrícolas no Estado de São Paulo, sendo realizado em solos gerados a partir de diferentes materiais que conferem, naturalmente, variações na constituição química e mineralógica destes, além de poderem, ou não estar contaminados por metais tóxicos oriundos dos métodos defensivos. Com o objetivo de quantificar os atributos químicos e os teores de metais pesados do solo foi realizado um estudo comparativo entre solos assim cultivados, das regiões das cidades de Mogi Guaçu e São José do Rio Preto. Este estudo envolveu a determinação do pH do solo, análises volumétricas para quantificação dos teores de matéria orgânica, Ca+2, Mg+2 e Al+3 , espectrofotômetro de chama para o estabelecimento dos teores de Na+ e K+ e espectrofotômetro de absorção atômica para determinação dos teores de Cobre, Zinco, Cádmio, Cromo, Níquel e Chumbo. O solo da região de Mogi Guaçu apresentou-se mais ácido devido, provavelmente, a uma maior concentração de Al3+. Apresentou, também, teores mais elevados de matéria orgânica. Os solos de ambas as regiões apresentaramse deficientes em Na+ , K+ , Ca+2 e Mg+2 . A análise realizada para os metais pesados mostrou uma elevada quantidade de Níquel observada nas amostras de solo da região de São José do Rio Preto e, Níquel e Cobre, nas de Mogi Guaçu, com valores classificados como de prevenção, de acordo com os Parâmetros Orientadores da CETESB (2005). Estes teores de alerta devem-se, muito possivelmente, à adição exagerada de defensivos agrícolas.

Objective: To assess the attitudes and knowledge about hepatitis by scholars and dental practitioners from Recife and its metropolitan region. Method: The research protocol was submitted and approved by the Ethics and Human Research Committee of the Federal University of Pernambuco. There were included 230 undergraduate students in dentistry and 104 dentists who exercise their professional activity in Recife and its Metropolitan Region. They signed a consent form and answered a questionnaire, the evaluative instrument, with objective questions about biosafety, transmission of hepatitis and sexually transmitted diseases. Results: About the types of hepatitis 133 (57.8%) students and 61 (58.7%) professionals claimed to know the types A, B and C. Concerning transmission 31 (13.5%) students and 25 (24.0%) professionals said that the main route of transmission were sexual and bloodstream respectively. Relating to imunization 221 (96.1%) students and 99 (95.2%) professionals reported that have been vaccinated against hepatitis B, however, only 126 (54.8%) students and 55 (52.9%) professionals have followed the immunization’s schema. Regarding the cleaning of the office equipment, 18.7% of the students replied that they do not know who does it. 56.7% of professionals said that it was performed with alcohol 70 ° GL.Conclusions: The findings indicate that there is a concern for biosafety but the knowledge about the forms of hepatitis transmission and biosecurity measures need to be better settled.

The global energy scenario is currently a widely discussed topic, with growing concern about the future supplies. Thus, much attention has been dedicated to the utilization of biomass as an energy resource. In this respect, orange peel has become a material of great interest, especially to Brazil, which generates around 9.5 million tons of this waste per year. To this end, the authors studied the kinetics of the thermal processing of dried orange peel in inert and oxidizing atmosphere. The thermodynamic parameters were determined by the Ozawa-Flynn-Wall method for the global process observed during heating from the 25 degrees C up to 800 degrees C. The thermal analysis in air and nitrogen showed 3-2 stages of mass loss, respectively, with approximately 20% residual mass under a nitrogen atmosphere. The increase in the values of activation energy for the conversion points between 20% and 60% for thermal effects in air and nitrogen atmosphere was observed. The activation energy obtained in an oxidizing atmosphere was higher than that obtained under a nitrogen atmosphere. The fourier-transform infrared spectroscopy and X-ray diffraction analysis showed that the material has a high level of complexity with the presence of alkali and alkaline earth groups as well as phosphate, plus substances such as pectin, cellulose and lignin.

The aim of the present study was to verify, through the response surface methodology, the optimum conditions for the combined use of aqueous extract of white lupine (Lupinus albus L.) and tropical pitanga juice (Eugenia unifl ora L.) in the development of a drink. Therefore, the independent variables were represented by the volume of aqueous extract of lupine (mL) and by the volume of pitanga juice (mL). The dependent variables (responses) were obtained through sensory test of acceptance (“appearance”, “aroma”, “taste” and “overall acceptability”). The combined optimization of the variables pointed the second formulation (50mL of aqueous extract of lupine and 30mL of pitanga juice) of the experimental project as the most adequate. In conclusion it was possible to get a drink with attractive sensory characteristics using aqueous extract of white lupine and tropical pitanga juice. The usage of response surface methodology made possible the determination of regions of maximum acceptance for each attribute evaluated in the formulation of a drink with aqueous extract of white lupine and pitanga juice, with a minimum of tests.
